Two extreme and one mixed procedures for designing a noise hazard prevention program are discussed in this paper. The two extreme design procedures (engineering-based and HPD-based) yield upper and lower bounds of the total noise control cost, respectively; while the mixed design procedure provides an optimal noise hazard prevention program within a given total budget. The upper bound of the workforce size for job rotation is approximated using a heuristic procedure. Six optimization models are developed and utilized by the mixed procedure to eliminate or reduce excessive noise levels (or noise exposures) in an industrial workplace. The mixed procedure also follows the OSHA’s hierarchy of noise control. A numerical example is given to demonstrate the application of the proposed design procedures.

Korea has the highest suicide rate in the world, and firefighters have the highest suicide rate among the professional population. As a result of the study, post-traumatic stress disorder education is essential in all occupations. Post-traumatic stress disorder is the most common disease and the biggest obstacle for firefighters in Korea. Firefighters who have suffered physical and mental damage in many types of disaster sites due to their extreme occupations are rapidly increasing the suicide rate in recent years. In order to maximize the effect of job training, education on post-traumatic stress disorder from new employees to leadership training is urgently needed.

With the deepening cooperation between China and South Korea in the field of film, the ways of cooperation between China and South Korea are becoming more and more diversified. "One text, two productions" film cooperation mode refers to the filmmakers of two countries sharing script resources, using the same script to create films separately. South Korean Extreme Job(극한직업) and Chinese Lobster cop(龙虾刑警) are the products of this cooperation model. The scripts of the two films originated from the China and South Korea story joint development plan(중한시나리오공통개발프로젝트) in 2015. After winning the award, the script were filmed by Korean and Chinese filmmakers. Filmmakers in two countries adapted the script to different degrees according to their respective cultural backgrounds and aesthetic characteristics. The film cooperation mode of "One text, two productions" promotes the development of transnational cooperation and opens up a new way of film cooperation.

This paper finds a solution in the social context which cannot be explained thoroughly by well-timed release date, revival of comedy films, and the attraction of Lee Byeong-heon's comedy etc. while it throws question of how the film, Extreme Job captivated 16 million audience. The incredible hits of Extreme Job cannot be explained by analyzing the text alone. After this essay investigates a function and a role of comedy as a public sphere, it examines people's desires and wishes in the comedy and other genres since 2008 when the conservative government has seized power. Since 2008 a series of dark tone's action thriller, social problem film, and disaster film have emerged, these genres showed absence of public security, crisis of democracy and criticism against rulling class. On the other hand, hit comedy films have showed escapism such as weepie, nostalgia, and fantasy at the same time, generally. Although Veteran (2015) is not full-blown comedy, after this film's big success, "comic mode" has gradually revived. A light tone's films which are truer to genre rules has started representing the wishes of people toward social reforms and changes. Meanwhile, "Candlelight Protest" served as a momentum to recover the democracy which has been in crisis, but it could not lead changes in economic and daily lives. Exreme Job can be read as a question how we will survive since "Candlight Protest." The lives of detectives as self-employed workers who has taken over a fried chicken restaurant for going undercover are appearances of ordinary persons who must survive in the edless conpetition. Furthermore, this film shows a dream of a "great success myth" which becomes well-known as a famous restaurant and a self-management such as brand-naming and an exapansion of franchise business. We can read ganster's chicken franchises as a huge distribution industry which disturbs market system by delivering drugs secretly. While applauses that we give to the police having identities of self-employed workers which sweeps the ganster are giving support to oridinary neighborhood like us, they are also wishes of people who long for the restoration of publicness of police in the market which is becoming increasingly privatized today. A significance of this essay is to examine Extreme Job in terms of the geography of film genres and the revival of comic mode sicne 2008 at the macro level, and is to read the film in the perspective of the problems of economic and daily lives which has been still unsolved since "Candlelight Protest" at the micro level.

The purpose of this study is to measure family stress, family resources, copying strategies and the types of family system. For this purpose, the data were collected from healthy families(231) and clinic families(103). The main results are as follows: 1. Partially family stress, family resources, copying strategies was different by the demographic chrateristics(age, yeares of marriage, job, education, family life cycle family income religion and types of family system). 2. The type of family system was meaning factor for the family stress study. 3. In the case of healthy family, family stress was negative related with family resources, but healthy families used copying strategies variously. 4. In the case of clinic family, family stress was related with family resources and copying strateges strongly. 5. Classifying the types of family system, clinic families were classified extreme family(20.5%), midrange family(39.7%), balanced family(39.7%) and healthy family were classified extreme(13.1%), midrange family(25.8%) balanced family(61.1%).

When a electric power cable is installed in the air for newly or exchanged working, it is necessary at all time to hold a constant tension for an overhead power cable. And also a pendanted power cable is an extreme job to have work in a high sky. For this reason, the objective of this paper developments working robot for preventing disaster that tension of cable installed automatically power cable to hold a constant. So the working robot works at all the time two tasks for mobil and tension it come into a inference between two tasks, control is difficult. Control methode needs to suppress inference of two tasks. In this paper, for installation of overhead power cable, the scheme and control methode of working robot is presented. the robot work at a same time tow tasks that have hold a constant tension of the power cable and move a constant place while unfasten a winding cable at a drum on a chassis. Working robot consist of three parts with mobile system, tension system and control part. As it is applied the feedback/feedforward control, methode of hybrid control is established to suppress that interference come into between two tasks. The simulation programs is made out using models of mobil and tension system, and a proposed controllers. In accordance with simulation, the model of each systems is discussed to make out proper. And also parameters of controllers is selected a suitable value and the driving performance of robot is evaluated.

This study has an objective to analyze the causal relationship between the emotional labor of the members in the private security firms and its effect on their job stress and validity of the organization. To carry out the study, I established a population of private security guards working at the security firms in Seoul. Then a total of 700 question naires were sent out for the survey using the random sampling method of clusters. The study was carried out over about four months, from May, 2014 to September, 2014. A total of 676 questionnaires were used for the final data. 24 questionnaires were excluded either because they were not returned or contained extreme value. In this study, a statistical package of SPSSWIN 18.0 and AMOS 18.0 were used in the data analysis and the causal relationship was verified using the covariance structural equation. The analysis showed the emotional labor to have a positive effect on the validity of organization but a negative effect on the job stress at the statistical level of p<.001 and the hypothesis was adopted. The hypothesis regarding the job stress was also adopted because job stress was found to have a negative effect on the validity of organization at the statistical level of p<.001. In addition, job stress was found to have a negative effect on the relationship between the emotional labor and validity of organization at the statistical level of p<.001. As a result, the hypothesis about the job stress would function as the parameter was only partially adopted.

Purpose: The purpose was to investigate the literature on depression among South Korean nurses in order to identify overall trends regarding depression. Methods: Forty-five papers published between 1998 and 2017 in three Korean databases-RISS4U, DBPIA, and KISS-were analyzed. Results: Depression showed significant positive associations with job stress, burnout, intent to leave, and somatic symptoms such as fatigue and trouble sleeping. Poor work environments such as staff shortage, work overload, and shift work were also positively associated with depression. Higher job satisfaction, resilience, self-efficacy, self-esteem, and social support were negatively correlated with and acted as significant buffers against depression. Conclusion: These results indicate that healthcare policymakers must pay more attention to the management and prevention of nurses' depression. In order to effectively do so, poor work conditions, which involve long working hours, high patient-to-nurse ratios, and extreme workloads, should be improved. Simultaneously, nursing managers should implement initiatives such as counseling and competency improvement programs, and stress management to reduce and prevent depression among nurses and strengthen their positive competency. Also, further research is required to clarify the prevalence of depression in South Korean nurses, with more meta-analyses also required to identify variations in depression rates owing to various factors.

The aim of this study was to evaluate the prevailing ergonomic conditions regarding low back injury in an assembly factory, In this study, analytic biomechanical model and NIOSH guidelines were applied to evaluate risk levels of low back injury for automobile assembly jobs. Total of 246 workers were analysed. There were 10 jobs with greater back compressive forces than 350kg at L5/S1. Also there were 44 jobs over Action Limit in terms of 1981 NIOSH guidelines. This could in part be explained by the ergonomic conditions of the companys analysed as not hazardous, with a relatively low duration of 'combined' extreme work posture. However, more ergonomic intervention could be done based on those results.
