The Hurt Locker When There Is Nowhere Else Left to Run

The Hurt Locker When There Is Nowhere Else Left to Run Introduction. Diving into the Psychology of the Hurt Locker: PTSD For those who have seen the terror of war, the given experience is a point of no return – there is no way for one to look at the world in a different view; the bloodbath becomes the only way possible picture of reality. Because of the horrible experience that the characters in The Hurt Locker had, the resulting acute post-traumatic stress disorder comes as a fee for surviving through this hell.Advertising We will write a custom essay sample on The Hurt Locker: When There Is Nowhere Else Left to Run specifically for you for only $16.05 $11/page Learn More Locking their pain within, as if concealing it in a secret locker, the characters are to suffer from the PTSD for the rest of their lives. As a matter of fact, the above-mentioned means that peaceful life becomes impossible for the lead character, the only survivor in the battle, forcing him to leave the realm of the family and enter th e battlefield once again. Revealing the Symptoms: Watch the Characters Agonizing However, there is a considerable difference between a movie and reality. In the real world, the people with PTSD are supposed to display certain symptoms that can be attributed only to the specified disorder, case in pint being the PTSD, while in a movie, some symptoms can be more subtle or, on the contrary, exaggerated for the sake of the dramatic atmosphere. Considering The Hurt Locker in particular, one must mention that the key symptoms of the PTSD are revealed quite soon: â€Å"Sgt. JT Sanborn: Im not ready to die, James. SFC William James: Well, youre not gonna die out here, bro† (The Hurt Locker). In addition, the above-mentioned symptoms correspond to the standard PTSD symptoms for the most part, since PTSD patients can be characterized by distressing, persistent anxiety or maladaptive behaviors to reduce anxiety (Myers). Concerning the Casual Factors: The Underlying Message There is a rh yme and reason for every change in the life or personality of a human being; the given rule is especially true for mental and psychological disorders, which are, as a rule, a result of a severe psychological trauma (Xenakis). Analyzing the movie, one has to mention that for William James, the leading character, the key factor that caused the PTSD was the war itself, with all its violence, murder and pointless sacrifice. The given state displays a lot of similarities with the definition of key PTSD factors offered by Myers: â€Å"The complaints of battled-scarred veterans [†¦] recurring haunting memories and nightmares, a numbed social withdrawal, jumpy anxiety, and insomnia- are typical of what once was called â€Å"shellshock† or â€Å"battle fatigue† and now is called post-traumatic stress disorder (PTSD)† (Myers 604), namely, the one that severe war traumas and the explosion to violence lead to a complete reestablishment of one’s life values. The Received Treatment: When Actions Are More Efficient than Medicine As it has been explained above that the PTSD can hardly be cured; in the light of the above-mentioned, it would be a silly idea for a movie claiming to be realistic to the last scene to offer a plot where William is successfully treated or even offered certain medicine. Quite on the contrary, The Hurt Locker makes it obvious that some of the war wounds cannot be healed, and PTSD is one of those wounds (Serlin).Advertising Looking for essay on psychology?

At some point William’s PTSD stops seeming a disorder and rather appears to be a different vision of reality, which is completely incompatible with the civil life. Hence, William’s return to the army can be conside red as the fact that, completely changed by war, he no longer belongs in the civil society and chooses the realm where he belongs. A peculiar portrayal of escapism, the given scene adds much to the character development. PTSD and the Characters’ Personal Life: Concerning the Impact Because of the awful slaughter which William saw in the battlefield, he is not able to live among the rest of the people anymore. He even cannot look at his son playing carelessly without a bitter remark: â€Å"And then you forget the few things you really love. And by the time you get to my age, maybe its only one or two things. With me, I think its one.† (The Hurt Locker). William no longer can live in civil society. Walking in the Characters’ Shoes: Life with PTSD It seems that living with this kind of a mental disorder is much like feeing completely out of place all the time. As a matter of fact, William must have felt like a living dead waking among the living ones, since he coul d not share their emotions; neither could he be happy just for a while – constantly on alert for something bad to happen, he felt that peaceful life is no longer his realm. Overall Reaction and the Portrayal of the PTSD Disorder Hence, it can be considered that the idea of the PTSD disorder developing within the minds of the people who have faced the dread of war has been portrayed in the movie in a rather impressive way. Making the audience go through all the tortures that the lead character faces, the movie creates a very authentic atmosphere, portraying the people whose idea of reality has been replaced with the war strategy and the heat of the fight. It is important that the actors play their roles in a rather subtle way, which makes the impression even greater, and the images of the people suffering from PTSD even more memorable. Hurt Locker.

My concept of Modernism in Literature

My concept of Modernism in Literature ÂÆ'‚‚ ÂÆ'‚‚ ÂÆ'‚‚ ÂÆ'‚‚ ÂÆ'‚‚ ÂÆ'‚‚ ÂÆ'‚‚ ÂÆ'‚‚ The movement known as "Modernism" began in the first decade of the 20th century and was a reaction against all aspects of Victorianism. Literary interest shifted from the external to the internal, to the psychology and motivation of characters and their roots in deeply shared experience, influenced by the theories of Sigmund Freud and Carl Gustaw Jung. Joseph Conrad, D. H. Lawrence, E. M. Forster among others, explored mind and feeling in fiction still largely conventional in narrative and dialogue. Virginia Woolf and James Joyce, however, experimented with the "stream of consciousness" to express a character's thoughts more directly. Poetry broke even more with the past, replacing traditional prosody with "free verse" and favoring the shorter poem with sharp, concrete imagery. This period was marked by a more colloquial and relaxed use of language. New styles allow ed the reader a more open and less directed approach to the text. Scenes and topics once banned from literature were now.Admitted, with taboo words appearing in print and a more explicit presentation of sexuality and human differences.What is more, the 20th century is above all, in art and in literature, the century of the individual. Main concern of the comparatively new science of psychology is personality. The psychology of personality development describes an evolution within the lifetime of a person. A whole series of tensions are created between the "known" and the new, the static and the dynamic. The tension between the idea of freedom and the idea of responsibility. Culture and personality interact, and help shape and explain each other. In Modernism, there is reflected the modern view of man, an understanding of his motives, of the forces, which shape him, and of the values, images and meanings, which are both his interpretations of experience and the shapers of his...

Perception Assignment Example | Topics and Well Written Essays - 250 words

Perception - Assignment Example In addition, we continue to modify our schemas as we experience new events or situations and learn from them, which enable our ideas and perceptions to evolve with time (Kesteren et al, 2012). Generally, schematic perceptions are based on events that we compare to other events, running the risk of oversimplifying events. Indeed, due to all the information that we take in, coupled with the need to simplify events and experiences, people tend to categorize events, which allows for immediate response based on established perceptions about these events (Kesteren et al, 2012). As a result, we do not need to perceive each football player whether from Spain, England, or Italy as unique categories, for example, instead identifying them as members of the football player category, which enables us to respond accordingly. Similarly, when one encounters other people, they tend to perceive them in terms of category, instead of unique individuals they have not encountered before, based on nationality, religion gender, or race. These categories are referred to as schemas and constitute cognitive or knowledge structures that organize incoming information, hence influencing how the individual perceives further information about events and people and responds to them (Kesteren et al,

Negligence Case Study Example | Topics and Well Written Essays - 750 words

Negligence - Case Study Example does not have a policy of requiring a background check on persons hired for any positions with ABC Properties, Inc. In addition, when you investigate Rob's background you find that Rob has a criminal record including convictions for robbery, sales of narcotics, and attempted rape. Mary wishes to sue ABC Properties, Inc. for damages as a result of the assault on a negligence theory. Negligence may be defined as intentional or unintentional breach of duty one is obliged to perform under existing laws. Under the United State of America laws, negligence is equivalent to tort. A tort is a private or civil wrong or injury, other than breach of contract, for which a court of law may provide a remedy through a lawsuit for damages or payment of compensation. When a person violates his/her duty to others created under general or statutory law, a tort has been committed ("What is a tort) In order for tort to exist, four elements must exist namely: 1) the existence of a legal duty owed by a person to others; 2) the breach of the duty by one person (negligence); 3) the breach of the duty being the proximate case of damages suffered by a person; and, 4) damages incurred by a person. Each of the four elements of a tort typically must be present to be compensated ("What is tort"). An example of compensable negligence is negligent hiring. ... parties to actions which can create legal liability ('Negligent hiring practices"). In the United States of America, an employer is obliged to take several measures before hiring an applicant ("Negligent hiring"). The most important of these measures is to conduct a background check and references to determine whether the applicant has a criminal record or has a dangerous or untrustworthy character. If an employee performs a violent or criminal act while working, such as rape, murder, or robbery, the employer can be held liable for torts for negligent hiring if it will be found out that he/she did not exert effort to perform the required obligation to conduct a background check before the employee who caused the unlawful act (Employer Liability for Employee's Bad Acts). In this case, it is very evident that the employer was negligent in hiring Rob as an employee and holding a key position in the company. First, the employer did not perform a background check that is required for him to do under the US laws before hiring Rob. Should he have conducted a background check, he should have found out about the criminal record of Rob and probably, could not have accepted him in the company. And should Rob was not accepted in the company, he will not have any access in entering the room of Mary, thus, the crime committed against her could not have been possible done. The four elements of tort were all consummated, therefore, Mary have a cause of action for negligence against ABC Properties Inc. Works Cited "What is tort". FreeAdvice.com. (Online).

Response paper - Essay Example Although the demise of the Aztec empire opened up the New World for European settlers, it is a tragic event when seen from the viewpoint of the natives. Their millennia long indigenous culture and civilization was abruptly and most violently cut short by the foreign conquest. In my opinion, rather than merely being a historical fact, this tragic facet to this historical episode should serve as a warning for contemporary politicians and policymakers, and make them realize that greedy ventures lead to humanitarian losses. I would like them to understand that while Spain and later European contingencies benefited from this conquest, from broader perspective humanity was the loser. Another aspect of the book I was most impressed with is its objectivity. Although author Miguel Leon-Portilla was trained in western scholarly tradition, his analysis and presentation does not betray this fact. At the same time, the empathy shown toward the disadvantaged Aztecs is matter of fact and not melodramatic. In this regard I like the subaltern approach adopted by the author in constructing history. I appreciate this book for features such as these. The extensive research conducted by the author is also quite impressive. Not only did he peruse primary sources for gathering evidence (which are in indigenous Aztec language), he also gives numerous cross references for further study, which is useful for college students like me. The detailed list of bibliographical entries at the end of the book is another handy feature. As I read through the book, I was able to appreciate the effort that went into researching this book. For example, previous to this work there was scarce scholarship on pre-Columbian culture in Mexico and the Americas. This book fills that void that its value cannot be overstated. The author also succeeds in bringing lots

Gender-role in Advertisement Essay Example for Free

Gender-role in Advertisement Essay This paper explores gender-role in modern advertisement. Sample modern-day advertisements will be analyzed in relation to gender-roles. Gender-role refers to a person’s way of actions and thinking that is identified as either related to male or female characteristics (Haig, 2004). It is a set of expectations on how females or males should think, behave, and feel. It is in the adolescence stage that male and females start to define their roles while their gender is intensified by conformity to transitional gender-roles in during puberty (Hill Lynch, 1983), which indirectly signals that they begin to act in ways that resemble the stereotypic female or male of their culture (Huston Alvarez, 1990). In addition to the demands of work and changing trends in the society and the increased number of employed mothers in the mid twentieth century, adolescents exposure to the media is considered to have a possible impact on their attitudes and perceptions about gender relationships, identity formation, and gender-roles (ODonnell ODonnell, 1978; Durkin, 1986; Lovdal, 1989; Richards Duckett, 1994; Dietz, 1998; Hovland et al. , 2005). The effects of advertisements to the perpetuation of gender-role stereotypes have received considerable importance in research and it has been debated whether it stereotyped advertisements have long term or short term impact on people’ own gender-role and whether advertisements with stereotypic portrayals gain more profit or does not have significant influence in people’s buying behavior at all. Effects of media in gender-role There are many factors that that affect gender-role development and the media is considered to be one (Golombok Fivush, 1994; Durkin, 1995). Dietz (1998) asserted that the media, in addition to environmental or social factors, affects people’s perception of gender-roles. The impact of advertising on audiences is often explained by social learning theory or by theories that are based on it. The argument is that, as people are repeatedly exposed to advertising images, they tend to internalize the advertisers views of themselves and others. The more ubiquitous the images are in advertisements, and the more frequently they see the advertisements, the deeper the audience identifies with the images. In addition to social learning theory (Bandura, 1977), framing research or frame analysis, introduced Goffman (1974), was used to obtain empirical evidence regarding the effects of media portrayals in people’s thoughts and consciousness. Framing assumes that the media frame reality is used to explain how people perceive and think about gender-roles because of the things they see and experience. Framing is used as a remedy sort in selecting a particular aspect of a perceived reality in order to emphasize, convey, or interpret something. However, framing may directly or indirectly influence people’s judgments on recognizing ideas presented in advertisements (Entman, 1993). Another issue on the effects of media is identified by Mead (1962) in his theory, arguing that individuals’ characterizations in the media affect children’s attitudes, relationships with other people, and behavior expectations. When traditional feminine or masculine roles become distinctive and children starts to identify with a particular gender-role, they are likely to expect specific characteristics and behaviors from females and males. Gender-role stereotyping negatively affects young individuals’ attitudes towards males and females since traditional portrayals of women are usually portrayed as dependent, obtaining approval from family and males, weak, victims, supportive of mens roles, sex objects, and adornment rather than individuals (Hall, Iijima Crum 1994; Artz, Munger, Purdy, 1999). As a result, these negative or substandard characteristics of women adversely affect children’s perception that women may ever find it difficult to attain gender equality and function as effective as men do in the society. This female portrayal restricts young females to think of achieving beyond their potential because many attributes, activities and traits are being designated as inappropriate for their gender (Dietz, 1998). Traditional stereotyped gender-role portrayals in advertisements Most advertisements portrayed both males and females stereotypically. Since 1950s, significant changes in gender-roles have occurred as the division of labor has become less distinctive and the entry of increased number of women into the workforce where professional positions, which were used to be exclusively for men, have opened opportunity for them to progress. Images of men and women in advertising in the early times have been heavily stereotyped. Men were depicted as independent, active, assertive, work-oriented while women were portrayed as dependent, passive, and domestic. Advertisements in the 1970s to 1980s continued to portray gender-stereotyping due to the difficulty of presenting people without specific gender-roles, especially when advertising specific products of particular gender. The strategies of advertisers in attracting people’s intentions and behaviors were more likely to favor gender-stereotyped representation since the public was more familiar and comfortable with gender-stereotyped advertisements (Morrison Shaffer, 2003). Gender portrayals in the context of advertisements were found to be predominantly stereotypic with dominant males and nurturing females in the mass media, music, film, as well as the print media. Although changes in the society and culture have been apparent, advertisements still rely upon women’s roles as subordinate. Women’s subordination was a useful tool in selling a wide variety of products such as alcohol, medicine, cigarettes, perfume, and vehicles. Constant exposure to derogatory portrayals of females in advertisements may result to socially induced depression and lowered levels of aspirations in achieving ones goals. Women portrayal as subordinates has been consistently practiced and presented in advertising until today although some changes and reversions have been observed (Mclaughlin Goulet, 1999). Advertisements usually portray men as being strong who are expected to have jobs that require much physical strength. They are portrayed as being the authority, dominant, having higher intelligence, becoming public figures, belonging to upper-middle class, being able to take medicine, law or business courses, aggressive, and sometimes gentlemen or bad guys. At home, men are portrayed to use car wax, auto parts, carpentry tools, motor oil, and lawn mowers. Women are rarely depicted as professionals in advertisements (Dietz, 1998). When women in advertisements are presented as professionals or experts in the products they advertise, they are often backed up by male figure or an authoritative male voice-over to strengthen the efficiency of convincing the audience since males were viewed as the authority (Lovdal, 1989). In traditional male magazines (e. g. , Esquire and Field Stream), gender-role stereotyped advertisements that portrayed men with masculine or manly activities have not decreased as much as the traditional female and general interest magazines. Although there have been some trends toward less stereotypic portrayals of masculine images in some print media advertisements, the traditional stereotype of the male gender still provides cultural representation (Furnham Thomson, 1999) Women are stereotypicly depicted in relation to beauty, physical attraction, family, domestic responsibilities, parenting, occupations such as teacher, waitress, masseur, bride, actress, secretary, vendor, household cleaners, maid, model, guest relations officer, and the like, as well as negative representation like evil, witch, possessions of men, passive, deferent, object for men’s pleasure. At home, women are portrayed to take care of every member, do all the chores, and maintaining relationships. They are often portrayed as supportive wives, mothers, sex objects, dependents, lack exploration, skills, knowledge, credibility, self-expression, and sense of mastery. Advertisers market products in magazines, like in television, using young, professional women as a product of beauty techniques and methods in order to attract and keep handsome, lucrative, and sophisticated men. Comic strips and children’s books also continued to adopt and support traditional portrayals of women in the society. For instance, illustrations show traditional female activities or a situation in which there is a dutiful wife in the bathroom or kitchen wearing an apron to model cleaning products, kitchen wares and appliances or food (Dietz, 1998; Peirce, 2001).

Batch Reactor As A Plant Engineering Essay

Batch Reactor As A Plant Engineering Essay What is a plant unit. All Equipment that make up a plant can be divided into 3 different categories or levels, the highest being the Plant as a whole, then the plant units and the lowest are the plant items. While the actual plant performs an overall production, the Plant unit refers to the main components of a Plant which perform a major production function of the Plant and without which the Plant can not continue its operations. A Plant unit is made up of items but it can be replaced as a whole (Anthony Kellyà ¢Ã¢â€š ¬Ã‚ ¦) In this Plant, the Batch Reactor receives raw materials from the raw material storage, processes them for a certain amount of time then transfers them to the centrifuge feed vessel. From the above diagram, it is obvious that the Batch Reactor is a major component of the plant and from its function it is seen that the reactor must process the raw material for progress to be made to the next stage of production. I am therefore concluding this as my explanation as to why the Batch reactor is a plant unit. Explain Your Reasons For Concluding That This Unit Is Critical For Production. Several Factors determine how critical a piece of equipment is to production. They include: Will the Equipment affect safety in the plant? Will the Equipment not working cause downtime in the plant? How easily can the Equipment be maintained? What is the cost of this maintenance? What is the current situation of the Equipment? (Paul Wheelhouse) Now each of the factors can be used to examine the Batch Reactor and after which an educated decision can be made. The Batch Reactor affects the safety in the plant because its function involves the heating of chemicals under pressure and its failure might cause the leakage of these chemicals or at the worst lead to an explosion in the Plant. If the Batch Reactor was to stop working, there would be prolonged downtime until it is fixed; this is due to the fact that the Reactor performs a major function in the Plant without which further production would come to a halt. The Batch Reactor is made up of a number of different items, some of which can be run-to-failure, but for the most an established schedule of maintenance must be made for. Without such a schedule, maintenance would be most difficult to carry out. The cost of maintaining the Batch Reactor may vary but if is not properly attended to; one fault might lead to another even bigger one so the cost of maintaining might increase. The items in the Batch Reactor have a life plan which is currently not being kept to; this means the Equipment requires monitoring to avoid random failure or prolonged breakdown and downtime. On the account of the above facts, it is my belief that the Batch Reactor needs to be labelled as critical. Extract Any User Requirements For This Designated Unit From The Plant Description. Are There Any Production Windows? What are User requirements? This simply refers to the specifications that are inbuilt in a piece of equipment so that it might be able to fulfil the end users needs according to those tasks which it is used to perform. In line with the plant description given on this particular Batch Reactor, a number of user requirements can be ascertained and these are listed below: To receive 18te of raw materials from the raw material storage. To remain sealed and heat its contents through a preset temperature / time profile by use of a temperature control system consisting of a thermocouple in a temperature pocket, a temperature controller and a control valve. That the control valve regulates the supply of low pressure steam. That its temperature alarm signal when the temperature exceeds 1250C. That all safety relief valves work in event of an increase of temperature past the safety limit of 1250C. That the bottom run off valve opens when the operation is complete and releases the contents from the Batch reactor to the centrifuge feed vessel by the discharge pump. That the operation lasts 10 hours only. What is a production window? This is a period during production in which maintenance procedures can be carried out without causing a halt in production. With emphasis on the Batch reactor it can be seen that there is a production window and this can be explained below. While the batch reactor makes 18te of product every 10 hours, the centrifuge processes this product at a rate of 1.5te an hour i.e. it would have completely used up the 18te of product in 12 hours. Since it takes 10 hours for the batch reactor to work, this would give a 2 hour production window in which it can be properly maintained. Also depending on the capacity of the centrifuge storage vessel, it is possible for the batch reactor to work overtime filling this feed vessel up and then be switched off and maintained while the centrifuge is operated using the previously stored produce in the centrifuge feed vessel. Extract Any Corporate Requirements for This Unit From The Plant Description. What are corporate requirements? These are the requirements which the upper management or Business sector of the company running plant desire from its industrial operations in order to make a suitable return on its investments (ROI). From the plant description the following corporate requirements can be made below: That its keeps to its scheduled annual shutdown period of 16 hours during week 40 each year. That all maintenance pertaining to the batch reactor abides by the permit to work system which controls all maintenance activities. That the batch reactor achieves a 25 year life and that the gearboxes achieve a 15 year life as well. That the batch reactor remains well-painted, clean and tidy at all times. Extract Any Legislative Requirements for This Unit From The Plant Description. What are legislative requirements? These are Plant requirements made by the Law, rules or regulations or the Country in which the Plant operates. They must be implemented in order for the plant to avoid sanctions or being shut down. In this particular plant description they include: That the Batch Reactor abides by the rules by the FDA and British pharmaceutical Society put in place for their license holders. All production and maintenance activities involving the Batch reactor comply with the Good Manufacturing practise (GMP). That the processes involving the Batch Reactor are as okayed by the quality standard ISO 9002. That the batch reactor conforms to the environmental standard ISO14000. That if used by the Pharmaceutical inspection team, the batch reactor must pass any risk-based inspections based on a DNV methodology that might be carried out. Comment On If Some of The tasks Designed For Shutdown Could be Done During Production Windows Or When The Plant Is Online. Could Any Of These Tasks Be Designated For Completion During Production Windows Be Completed Online? We have previous explained what production windows are and when a Plant is online refers to when the plant is carrying its usual operational procedures. From the work done previously in section 1.3, we now know that there is a definite 2 hour production window during which the batch reactor can be maintained while the centrifuge is working. In looking at the life plan for the batch reactor unit, there are a certain amount of tasks that could be done in 2 hours and should be moved from shut down to production window, these are: The replacement of the trim of the CV1 every 2 years. The pressure testing and inspection of the SV1 every 6 years. The visual check of the Agitator every 6 years. The SV2 pressure testing and inspection every 6 years. There is only one task put to be completed when there is a production window and it can be done while the Plant is online. This is the weekly visual check on the Agitator coupling, because if it is checked while online it might lead to the location of which wouldnt have being seen if the equipment was offline. Analyse The Recorded Jobs From The Computer Maintenance Management System (CMMS) For This Unit. Is There Any Evidence Which Confirms That The Life Plan Is Being Carried out? Is There Any Evidence To Say If The Life Plan Is Effective Or Not? What is a Life plan? All plant units or manufacturing stages in production are designed to have a certain life. To fulfil this, maintenance plans are put in place to achieve this expected equipment life and if possible, to exceed it. These maintenance plans are called Life plans. (Wheelhouse, 2008) On comparing the life plan of the batch reactor to the computer maintenance management system (CMMS) it can be seen that the life plan isnt being carried out. This is due to the factor that there is a remarkable difference between the standard time taken to maintain every single unit item in the reactor and the actual time the job was done in hours, meaning the maintenance done cannot be adequately planned for and could lead to excessive downtime. It can be seen that for this singular reason the life plan of the batch reactor is not capable of being effective. Use The Figures, Plant Description And The Data From The CMMS To Analyse The Unit Into Its Maintenance Causing Items. Using the figure 1 shown previously and the figure 2 shown directly above as well as the Life plan and the CMMS, the maintenance causing items can be broken down as done bel Batch Chemical Reactor CV1 Agitator Coupling Temperature controller Gearbox Motor bearing Oil seal Agitator Trim Agitator gear box Reactor Vessel Temperature sensor Pump Motor Pump bearing SV1 SV2 P1 V1 Vessel Jacket Figure 3: The Maintenance Causing Items in a Batch Chemical Reactor Develop your own life plan for these maintenance causing items using the task selection logic for Reliability Centred Maintenance.

Compare and contrast between your Life plan with the one described previously, comment on any similarities and differences. There are a number of ways in which my Life plan differs from the one previously given but there are also ways in which both are similar. Some of them are as listed below: To begin, the first detail that can be noticed when comparing both life plans is that since I used the RCM selection logic, my life plan carries much more details as I included the functions, functional failures, failure modes, failure effect and criticality of each subsystem or item. This will be particularly useful in settling up priorities as the criticality of each subsystem is set at low, medium or high depending on the considerations of safety, performance and impact of the subsystem or item on the rest of the plant. I brainstormed and added more failure modes and their activities than had being previously discovered or had activities planned for in the previous life plan so as to further prepare maintenance personnel to be able to tackle these failures if and when they do occur. I changed the time frame for certain activities to take into consideration the new 2 hour production window that was discovered earlier. This will help reduce the amount tasks that are done during a shutdown and therefore cut down the downtime which the plant undergoes. I increased the amount of time to be used to accomplish most tasks due to the fact that in the previous life plan, insufficient time was allocated to these tasks so therefore they couldnt be planned or executed properly within the targets set for them. Now in terms of similarities, I observed that the preventive maintenance and condition monitoring carried out on the Batch Reactor had ensured breakdowns were kept to a minimum so bearing this in mind, I retained all the activities from the old life plan and continued using them for the various items. I also continued to carry out maintenance activities at the same frequency that was mapped out in the old life plan as I believe that the punctuality with which activities were carried out improved the reliability of the equipment. CHAPTER 2 Describe The Philosophy of Total Productive Maintenance. What is TPM? Total Productive Maintenance (TPM) refers to a management system for optimizing the productivity of manufacturing equipment through systematic equipment maintenance involving employees at all levels.   Under TPM, everyone is involved in keeping the equipment in good working order to minimize production losses from equipment repairs, assists, set-ups, and the like. (http://www.siliconfareast.com/tpm.htm). The goal of TPM is to increase production while at the same time boosting employee morale and job satisfaction. (Venkatesh. J) This is possible because there would be less downtime as TPM is carried out by the Operators on the items or machinery which they use as they, the maintainers and Designers work as a team towards the total elimination of equipment defects in the Plant (Paul Wheelhouse). History of TPM TPM is a Japanese idea that can be traced back to 1951 when preventive maintenance was introduced into Japan from the USA. Nippondenso, part of Toyota, was the first company in Japan to introduce plant wide preventive maintenance in 1960. In preventive maintenance operators produced goods using machines and the maintenance group was dedicated to the work of maintaining those machines. However with the high level of automation of Nippondenso, maintenance became a problem as so many more maintenance personnel were now required. So the management decided that the routine maintenance of equipment would now be carried out by the operators themselves. This is known as Autonomous maintenance, one of the features of TPM. The maintenance group then focussed only on maintenance works for upgrades. For pioneering TPM, Nippondenso became the 1st company to receive TPM certification (wikipedia). Why Use TPM? For TPM to be used in an Organisation, everyone from senior management to the operators on the floor must be carried along and made to understand why this particular system is being used. For this to happen effectively, the Motives, Objectives and benefits must be fully stated out and properly absorbed. The table below gives a generic illustration: Motives of TPM Adoption of life cycle approach for improving the overall performance of production equipment. Improving productivity by highly motivated workers which is achieved by job enlargement. The use of voluntary small group activities for identifying the cause of failure, possible plant and equipment modifications. Uniqueness of TPM The major difference between TPM and other concepts is that the operators are also made to involve in the maintenance process. The concept of I (Production operators) Operate, You (Maintenance department) fix is not followed. TPM Objectives Achieve Zero Defects, Zero Breakdown and Zero accidents in all functional areas of the organization. Involve people in all levels of organization. Form different teams to reduce defects and Self Maintenance. Direct benefits of TPM Increase productivity and OPE (Overall Plant Efficiency ) by 1.5 or 2 times. Rectify customer complaints. Reduce the manufacturing cost by 30%. Satisfy the customers needs by 100 % (Delivering the right quantity at the right time, in the required quality.) Reduce accidents. Follow pollution control measures. Indirect benefits of TPM Higher confidence level among the employees. Keep the work place clean, neat and attractive. Favourable change in the attitude of the operators. Achieve goals by working as team. Horizontal deployment of a new concept in all areas of the organization. Share knowledge and experience. The workers get a feeling of owning the machine. Figure 4 .TPM table Source: An Introduction to Total Productive Maintenance (Venkatesh. J) For TPM to start properly, the OEE (Overall Equipment Effectiveness) should be calculated and a loss analysis performed to give both a baseline for continuous upgrading and ascertain the improvement priorities. This will allow the operator/core maintenance team to prioritize and then tackle the 6 classic losses of: Breakdowns Set-ups and changeovers Running at reduced speeds Minor stops and idling Quality defects, scrap, yield and rework Starting up losses The above losses add to the direct costs. Implementation of TPM attacks these and other direct (visible) costs as well as indirect (hidden) costs and follows each step in the production and supply chain from Management to the human resources to the Machine to the process, then to suppliers and finally to the customers (Willmott and McCarthy). Components of TPM Figure 4: Pillars of TPM Source: An Introduction to Total Productive Maintenance (Venkatesh. J) As shown above, TPM is made up of 8 main aspects which when combined present the full TPM package. They are: The 5 S which are primarily the foundation of TPM and involve organising the workplace. These are sorting, systematising, sweeping, standardising and self-discipline. Autonomous maintenance which refers to the operators handling most or in cases all of the maintenance concerning the machines which they operate. Kobetsu Kaizen means small improvements or changes for the better of the organisation. Planned maintenance entails scheduled maintenance which is done to ensure trouble free machines and equipments producing defect free products for total customer satisfaction. Quality maintenance is aimed at providing customer satisfaction by providing the highest quality through defect free manufacturing. Training to give employees a multi skilled edge. Office TPM to ensure administrative efficiency as well. Safety, health and environmental awareness to ensure zero accidents, zero health damages and zero fires (Venkatesh. J). Describe a Case Study Where TPM has been successfully applied The case study which I wish to use is that of RHP Bearings. This RHP Bearings branch which is in Blackburn, manufactures cast iron bearing housings for a variety of uses from agricultural machinery to fairground rides, and is one of seven RHP manufacturing sites in Europe owned by Japanese group NSK, the worlds second largest bearings manufacturer. How TPM was carried out. NSK acquired RHP in 1990, when the Blackburn site was under the imminent threat of closure because of high costs and the subsequent lack of competitiveness. Employing a staff of 93, TPM was then introduced to the site in 1993 but it didnt see much success till 1996 due to the fact that the earlier efforts to drive TPM had been largely theoretical and the workforce faded to see its relevance to the everyday running of the plant. In 1996 a maintenance company was brought in to do a scoping study of the plant, conduct a workshop and support two pilot TPM projects. The Plant Manager and the TPM facilitator then began to implement measures to ensure TPM was made directly relevant to the jobs of the staff. Operators were sent off to climb over their machines and log problems through a detailed condition appraisal, to establish a foundation for future TPM improvements. TPM was piloted on two key machines, the PGM core making machine in the foundry and the Shiftnal sphering machine in the machine shop, using a detailed seven-step TPM implementation programme: Collection and calculation of Overall Equipment Effectiveness (OEE) Data Assessing the six losses Criticality assessment and condition appraisal Risk assessment Refurbishment plan Asset care and best practice routines Regular review for problem solving TPM is applied to machines of all ages from new to 30 years old, ensuring that older machinery is brought up to modern specification and newer machinery is kept in as-new condition. The TPM was applied at the site by 9 different equipment teams focusing on specific machinery and involving 60% of the workforce. These teams included operators, maintainers, quality technicians and group leaders also drawing on help from personnel with specialist skills when necessary. Each Team developed a standard routine for their respective machines using: Autonomous Maintenance System (AMS) boards which show a schematic of the machine then tags with labels to show losses affecting availability, performance and quality. These labels are then used to generate TPM agendas for team meetings. TPM step notices which illustrate the machines progress in TPM seven step programme. Mainpac database which is used to gather machine performance details and calculate the OEE. Key performance indicators which the teams use to accesses their improvement and progress in areas of waste sand, Gas emissions, Kaizen, Customer returns, lost time incidents, injurious accidents, Audit and product conformance. Each team then has an activity board covering subjects such as milestone activities and previous days conformance result among others. To ensure TPM succeeded, Teams had to dedicate substantial time to carrying out laid down activities and held meetings as needed. Benefits of TPM Implementing TPM had both direct and indirect effect on the production system a combination of which generated major savings at RHP, Blackburn. Major Site-wide benefits were scored in the following areas: à ¢Ã¢â‚¬Å¡Ã‚ ¬400,000 running costs saved Unit cost reduced by 21% Scrap reduced by 8% Attracting increased capital investment currently at 15% of turnover and Customer returns reduced by 11% Increased customer satisfaction Improved safety record Environmental and quality awards Improvement in staff morale The two key machines (The Shiftnal sphering and the PGM core making machine) also had major total cost saving OEE improvements as well as other time saving and cost reduction achievements making the TPM well worth it (Willmott and McCarthy). Reliability Centred Maintenance (RCM) As Applied in a Section of a Plant What is RCM? RCM is a method for developing and selecting maintenance alternatives based on safety, operational and economical criteria. RCM employs a system perspective in its analyses of system functions, failures of functions and prevention of these functions (Jones, R.B). So RCM requires in-depth of the machinery, detailing all logic problems and their maintenance solutions and as such can be quite time consuming, for this reason it is usually used only on the critical equipment. The use of RCM methodology requires that 7 questions be answered: What are the functions of the Asset? What are the functional failures? What causes the functional failures? What happens when the failure occurs? How much does each failure matter? Can we predict or prevent failure and should we be doing so? How should we manage the failure if prediction or prevention is not an option?(Paul Wheelhouse) Now in order to answer the above questions, a System analysis process is used to begin RCM on any section of the plant. This System process will implement several steps, all of which define and characterize RCM and will methodically delineate the information required for the maintenance: Step 1. System selection and Information collection: Taking decisions as to what level of the plant at which to do the RCM and also choosing this system or section based on criticality i.e. based on function and impact on plant and environment. Step 2. System Boundary Definition: This involves creating an accurate list of what is or is not part of the section so an accurate list of components can identified and to establish what comes in and what leaves the System(IN and OUT interfaces). This is necessary to ensure the accuracy of the Systems analysis process. Step 3. System description and functional Block diagram: This is used to identify and document the essential details of a system that are needed to perform the remaining steps in a thorough and technical fashion. The five separate items are developed in this step: System Description Functional Block Diagram IN/OUT interfaces System Component list Equipment history Step 4. System Functions and Functional failures: involves classifying each OUT interface of the system into its functions and identifying the failures which might hinder these functions. Step 5. Failure Mode and Effect analysis (FMEA): involves analyzing each component failure to discover which have the potential to disruption their function and then detailing what exactly these effects could be. This is done using functional failure-equipment matrix. Step 6. Logic (Decision) Tree Analysis (LTA): the failure modes which pass through effects analysis will now go through this process. The purpose of this step is to further prioritize the emphasis and resources that should be devoted to each failure mode on the basis that all Authority (TVA). TVA is a power production plant wholly owed by the US government and equipment, functions and failures are not the same. The LTA identifies the failure modes in 3 aspects: Safety Downtime Economics (Finance) Step 7. Task selection: In this step, applicable maintenance tasks which are most effective to combat the detailed failure modes are listed, at the same time decisions on whether to run-to-failure or design out
