This study focused on the decreased effect of the work load on using the lower extremity supporter in kneeling posture. Fatigue measures included subjective discomfort ratings through the use of the Borg's CR-10 scale based parameters. The resting period and work method were considered as independent variables. The break time conditions are grouped into 10 seconds after work for 1 min and not exist break time. The method of work conditions are divided into four types. There are kneeling with the lower extremity supporter, kneeling with the knee protector, just kneeling and squatting. The result of the ANOVA of the shift value of subjective discomfort showed the followings: 1) There were differences as regards to the method of the work, the break time and the part of body($p{\leq}0.05$). 2) The lower extremity supporter showed the least subjective discomfort in other part of body except the upper leg.

본 연구는 청소년들의 시간제 노동경험이 비행경험에 영향을 미치게 되는 경로를 규명하고자 하는 목적으로 이루어졌다. 이를 위해 서울시내 고등학생 중 한 달 이상의 기간동안 시간제 노동을 경험한 학생 201명을 대상으로 자료를 분석하였으며, 주요 비행이론인 차별접촉이론, 사회통제이론, 권력자원이론에 기반하여 연구모형을 설정하고 구조방정식을 통해 이를 검증하였다. 그 결과, 청소년들의 주당 노동시간이 증가할수록 동료의 비행성향이 증대되고, 용돈의 소비수준이 증가하며, 학교적응 수준이 떨어지게 되고, 이것이 다시 비행수준에 영향을 미치는 것으로 나타나 세 가지 주요 비행 이론들이 적용될 수 있음을 검증하였다. 특히 주당 노동시간은 중비행보다는 경비행의 증가에 미치는 영향이 컸으며, 중비행의 경우 동료의 비행성향만이 유의미한 매개변인으로 확인되었다. 이러한 연구를 통해 주당 노동시간과 비행의 매개변인을 검토함으로써 비행의 증가를 막기 위한 개입지점을 찾을 수 있었으며, 이에 기반하여 노동경험 청소년들의 비행성향을 감소시키기 위한 학교, 가정, 노동현장에서의 실천방안에 대해 논의하였다.

Purpose: The purpose of this study was to identify the degree of satisfaction of part-time work of the mentally disabled and the factors affecting their job satisfaction. Methods: The subjects of this study were 106 part-time workers with mental illness in the city of B and Y. The data were collected from February 1, 2012 to May 30, 2012 using self-report questionnaires including the measurement scales of job satisfaction, family support, work volition and the degree of satisfaction with work environment. The data were analyzed using t-test, ANOVA, Pearson correlation coefficients, multiple regression with the SPSS/WIN 18.0 program. Results: The mean of score for job satisfaction was $61.8{\pm}13.84$. Job satisfaction was highly related to family support, work environment and work volition. The associated factor of the subjects job satisfaction were family support, work environment, work volition, and the period of employment. The combination of these four factors showed an explanation for job satisfaction at the rate of 80.2%. Conclusion: The results imply that job satisfaction needs to be increased for the job continuity of employees with mental illness. In addition to this, work environment, work volition and family support should first be improved for the increase of job satisfaction.

This paper presents a method of an automatic work time evaluation based on the verification of a disassemblability and assembly configuration. Even though a work time evaluation is an important field of concern for planning assembly lay-out, there are some limitations using cumbersome user query or approximated work time data without considering assembly condition. To overcome such restriction, this paper presents a method to mathematically verify assembly conditions based on the disassemblability, which is defined by the separability and stability cost. The separability cost represents a facility of the part disassembly operation, and the stability cost which represents a degree of the stability for the base assembly motion. Based upon the results, we propose a new approach of evaluating work time using neural networks. The proposed method provides an effective means of solving the work time evaluation problem and gives a design guidance of planning assembly lay-out in flexible manufacturing application. Example study is given to illustrate the concepts and procedure of the proposed schemes.

The purpose of this study was to empirically describe the everyday life of middle-aged adults in terms of their time-use activities. From the original '2004 Time dairy' Data, developed by the Korean National Statistical Office (KNOS), 17,684 respondents aged between 35-59 were selected. In order to categorize their activity patterns, work/labour, domestic labour, and spare leisure time were classified according to the action classification system. As a result, four dominant types were found: namely work-leisure, work-oriented, family-oriented, and leisure-oriented activities. Results of multinomial logistic analysis revealed that gender, age, socioeconomic status, job characteristic, and family structure were the major determinants on time-use. Compared with work-leisure, young middle aged women holding a part-time job with less income tended to be involved in a family-centered time use. Dual earners with lower SES status were likely to have work-oriented time schedules. Older men with relatively lower income were more likely to be involved in leisure-oriented activities rather than work-leisure activities. Multitasking behavior was a significant variable in explaining the four different types of time-use. Work-oriented group showed the highest level of time pressure as well as fatigue. Group differences in these measures, however, was not as large as expected.

Recently, Korean health care industry managers are paying more attention to customer oriented service, the rationalization of business administration, and quality control of service to adjust their business to outer environment since IMF bailout program. They are focusing on the cost reduction through remodeling the size and structure of man power, viz. labor flexibility. Nurses are not free from this juncture and contingent nurses are increasing fast. This article intends to verify the actual condition of two types of contingent nurses -part-time nurses and internship nurses-and to compare their job satisfaction to provide basic resource for efficient management of nurse man power. The concrete goals of this article are; Firstly, to verify the actual condition of their employment. Secondly, to compare their job satisfaction. And Thirdly, to the relation between employment condition and job satisfaction. To accomplish these research goals, a statistical survey was executed, in which 384 questionnaires - 66 for manager nurses, 318 for contingent nurses-were given to nurses working at 66 general hospitals-which have at least 100 beds-in Seoul. Among them, 121 questionnaires-of 28 general hospitals-were returned. Then, the data coded and submitted to mean, standard deviation, T-test, variance analysis (ANOVA), correlation analysis, multiple regression analysis with SAS program. The research results of the contingent nurses are followings: 1. Two types of contingent nurses shows similar age spans: they are mostly 21 - 30 years old and unmarried. But internship nurses have high level of educational career. Part - time nurses spread at general beds, out -patient part, intensive care part, operation part, etc, but internship nurses work mostly at general beds. 2. Two groups shows difference in actual employment condition: average employment career of part -time nurses is 7.0 months but internship nurses' is 2.0 months: average duty-on days per month of part - time nurses are 23.7 days but internship nurses' are 24.8 days. But there are little difference in average working time per day: 7.7 hours for part -time nurses and 0 hours for internship nurses. 3. The average wage per month for part -time nurses is 836,026 won but for internship nurses is 557,428 won-66.7% of part-time nurses'. Both groups are enjoying little additional pay. 4. Both groups are getting job not so much through advertisement of newspaper or hospitals as through acquainted person or college. 5. Both groups show very high level of job satisfaction: 3.2195 for part -time nurses and 3.2881 for internship nurses. But they show very low satisfaction on payment level compared with other categories and two groups show meaningful difference(P<.0001). 6. The multiple regression test reveals the factors related with job satisfaction: wage level, working part(OR or ICU), age, job career, and motive of contingent job-taking('because I can take care of family duties at the same time') influence positively: motive of contingent job-taking('because I can work regularly without alternation') influences negatively.

Background: Return to work after treatment completion is important for both cancer survivors and society. Financial distress is one of the factors that may influence the return to work in cancer survivors. However, this relationship has not been well investigated. This study aimed to determine the rate of return to work and its relation to financial distress among Iranian cancer survivors. Materials and Methods: This descriptive-correlational study was undertaken among 165 cancer survivors who completed their initial treatments and had no signs of active cancer. The Return to Work questionnaire and Financial Distress/Financial Well-Being Scale were used for data collection. Data were analyzed using SPSS statistical software. Results: After initial treatments, 120 cancer survivors (72%) had returned to work, of which 50 patients (42%) had returned to full-time work and 70 (58%) reduced their work hours and returned to part-time work. Cancer survivors also reported high levels of financial distress. In addition, the financial distress was lower among patients who had returned completely to work, in comparison to patients who had quit working for cancer-related reasons (p= 0.001) or returned to work as part-time workers (p=0.001). Conclusions: The findings showed that a high percent of Iranian cancer survivors had not returned to their jobs or considerably reduced working hours after treatment completion. Accordingly, due to high levels of financial distress experienced by participants and its relation to return to work, designing rehabilitation programs to facilitate cancer survivor return to work should be considered.
