The research was conducted by center for children's foodservice management in Hanam-si. In order to improve job satisfaction, a survey was carried out by working conditions and job satisfaction in children foodservice employees working at child daycare centers registered from January to April. Ninety-five surveys out of 120 were collected, and 76 surveys were analyzed. Job satisfaction consisted of four elements, working environment, welfare, human relationships, and job-itself, analyzed by general characteristics. Pearson's correlation was carried out between job satisfaction and intention to change job by Likert 5 scales using SPSS statistic program. The percentages of child daycare centers owned by civilians was 52.6%, high school education level was 65.8%, permanent workers was 68.4%, and less than 1 year of foodservice was 34.2%. Average scores of job satisfaction were as follows: working environment scored 20.6 out of 25 points, welfare scored 10.3 out of 15 points, human relationships scored 17.5 out of 20 points, and job-itself scored 13.2 out of 15 points. The lowest job satisfaction average was 'I get paid fairly regarding the working hours and the amount of work' with a score of 3.6 points. Job satisfaction based on facility type, age, education level, and working period did not show significant differences, whereas hired status, numbers of foodservice children, and intention to change jobs showed significant differences. Hired status showed significant differences with welfare satisfaction (P<0.05). Numbers of children showed a significant difference with welfare and human relationship satisfaction (P<0.01, P<0.05). Intention to change job showed a significant difference with four elements of job satisfaction (P<0.05, P<0.01, P<0.01). In conclusion, to improve job satisfaction of children foodservice employees, working conditions and welfare satisfaction should be increased.

Background: We hypothesized that the growing demand of Korean workers for work-life balance would change the factors influencing job satisfaction. We sought to verify our hypothesis by conducting a conjoint analysis based on the Korean Working Conditions Survey (KWCS). Methods: We analyzed the raw data of the KWCS, conducted by the Occupational Safety and Health Research Institute from 2006 to 2017. To complete the analysis, we counted on a conjoint model of analysis, typically used in the analysis of customer satisfaction. The dependent variable was the satisfaction of workers with their working conditions, and the independent variables were the job quality indicators identified by Eurofound. Results: The factors that have the greatest impact on working conditions satisfaction are summarized as follows: "physical environment" for the first wave, "adverse social behavior" for the second wave, "occupational status" for the third and fourth waves, and "management quality" for the fifth wave. "Earnings" were not a major factor in determining employee job satisfaction, and the relative importance index is decreasing. Conclusion: According to the results of the analysis of the tendencies of Korean workers, the factors that affect the satisfaction with the working conditions have changed over time. It is crucial to identify factors that affect working conditions to assure the health and productivity of workers. The results of this study demonstrate that policymakers and employers are required to attentively consider human relations and social environment at work to improve working conditions in the future.

This paper presents a new mode of expressing a 3D assembly work for creating a 3D CG animation without judgment by human from minimal required information. In the field of manufacturing, there are favorable movements in the utilization of 3D CAD for 3D simulation to shorten lead time for product development and pre-production. But simulating an assembly work has troubles to need huge quantity of manually input data. This paper discusses what minimal necessary information for creating 3D CG animations of assembly works is, focusing on the features of assembly works. Furthermore, a new mode of expressing a 3D assembly work is proposed as "state/change transition diagrams" (SCTD), which express arbitrary scenes in an assembly work as "state" and describe a sequential assembly work with "state" and "change", and the outline of its stepwise generation algorithm is also described. SCTD can be converted to a 3D CG animation of an assembly work without judgment by human. This paper focuses on the creating 3D CG animation of assembly works which workers use only their both hands.

This paper summarized the results of previous and recent studies on cumulative trauma disorders (CTD) and provides a prevention strategy for CTD and showed the results from a quite extensive survey with tables and figures. This is a follow-up study of Kwon (1993) 〔2〕. From the previous studies, Kwon (1993) showed that many people are exposed on CTD, but they did not only know the clear reasons why they got CTD, but also how to prevent or change their workstation〔2〕. Lee (1996) showed the result from both field survey and medical examination. He found that most frequent symptoms are CTS (nerve disorders) and tendon disorders 〔6〕. From these previous results, it is obvious that CTD patients will increase in Korean industries if we did not pay attention to this CTD problem. Therefore a proper education of Ergonomics, CTD prevention for workers and moderate changes in workplace are necessary. From 1998 and 1999 follow-up studies, there are still many people(23％) did not hear about CTD, CTS, or MSD. Only 42％ of respondents is exercising during or after work for short-time. Therefore, there are many rooms for prevention strategy of CTD and education for preventing CTD.

To investigate the risk factors of low back pain, an epidemiological study was carried out among male workers aged 20-55 employed in an automobile industry in Korea during the time period from February 1993 to October 1995. Workers participated to this study were divided into low back pain group(LBP) and control group, according to the self-reports by written questionnaires. General characteristics, medical history, work related factors, fatigue, and MMPI were compared between two groups. To clarify the relationship between job related low back pain and radiologic features of lumbar spine, radiographic study was carried out. The resultant data were processed for $x^2-test$, t-test, and stepwise logistic regression to confirm the adjusted odds ratios. The results were as follows: 1. History of back disease, lifting and carrying work, excessive physical fatigue, and weakend back strength of individual workers were directly associated with low back pain. Odd ratios of these 4 risk factors of low back pain were 5.07, 3.34, 1.49, and 1.22 respectively. 2. The frequency of low back pain history was significantly higher in LBP group. 3. Back muscle strength of lumbar spine of LBP group were significantly lower than control group. 4. The workers in LBP group revealed high fatigue symptoms. 5. In MMPI test LBP group showed higher scales in hypochondriasis, depression, hysteria, psychopathic deviate, paranoia, psychasthenia, schizophrenia, and hypomania. 6. LBP group were more frequently involved in lifting and carrying, working in awkward position, bending, twisting and using lower extremities. 7. LBP group were exposed more to vibration during working. 8. In the Analysis of radiographs of lumbar spine, Jacob's line not crossing fourth lumhar disc space, transitional vertebrae and lumbar displacement more than 4.4mm in standing lateral view were more frequently observed in LBP group than control group. Through these results, it is concluded that identification of previous history of back problem, change of work or working environment for workers with previous back problem and measures to relieve both physical and psychological fatigue of the workers are required for optimal management of work-related back problems among workers. In the present study, several results were different from the previous reports: Jacob's line not corssing fourth lumbar disc space, lumbarization, and vertebral slipping (spondylolisthesis) more than 4.4mm are related to backache. Meticulous studies are required to elucidate the difference.

미국 건설산업은 숙련된 기능공의 부족이라는 도전적 과제를 경험해 오고 있다. 이 문제는 다음과 같은 여러 원인들에 의해 야기된것이다. 건설산업의 이미지 저하, 훈련과 교육의 부족, 불분명한 경력관리, 임금의 저하, 노동인력의 구성변화. 건설인력과 관련된 이러한 문제점들을 근본적으로 해결하기 위해 Two-Tier Work Force Strategy라는 획기적인 접근방법이 Center for Construction Industry Studies (CCIS)에서 제안되었다. Two-Tier Work Force Strategy는 Tier I과 Tier II Strategy로 구성되어 있다. Tier I 전략은 기술이 떨어지고 단순작업이 가능한 기능인력을 활용하며, 많은 수의 현장관리인원을 필요로 한다. Tier II 전략은 상대적으로 잘 교육받고, 기술수준이 높은 소수의 기능인력을 활용하며, 그들은 기능능력과 더불어 관리능력도 갖추고 있어야 한다. 그들은 더 높은 급여를 받지만, 높은 기술수준으로 인해 더 생산적으로 일할 수 있고, 다중기술의 보유로 더 오래 현장에머물며, 안전, 품질, 공정, 그리고 원가적 측면에서 향상된 프로젝트 성과를 가져온다. Two-Tier Work Force Strategy는 근래의 기능인력에 대한 문제점을 해결하고, 미래에 더 나은 노동환경을 가져올 수 있는 방안이 될 수 있을 것이다.

This paper describes a web-based design review system as a knowledge management system relating reliability and safety system design. Since people's consciousness for safety and security become sensitive and increases the need of establishing a proactive prevention method for internal failures and relating risks in products. It also means that prevailing tacit knowledge in retired workers, in order to transform them to be easily used to support new system development, become more important. When considering safety and reliability design, at least two data sheet are necessary; Failure Modes and Effects Analyses (FMEA) and Risk Assessment (RA). These two data are practically made separately. However, it includes the concerns that a risk by failures during long-term use may not be noticed. To overcome this insufficiency, a support tool for integrating reliability evaluation and risk assessment data simultaneously is expected to be revealed. The authors have then developed a web-based design review system for reliability and safety system design. The system include various profitable functions; making FMEA and RA sheet, retrieving past data sheet for engineering change management and new product development and web-based discussion to increase the efficiency of discussion. The system is applied to one practical development works in order to demonstrate its effectiveness that is to be made clear by interviewing user's qualitative comment.
