Several working fluids for Organic Rankine Cycle(ORC) were recommended by many researchers. However, the recommended optimal working fluids were not exactly same because the operating conditions of ORC and application were different. The major parameter to select the working fluid for ORC was the temperature of available thermal energy. In this study, low-grade thermal energy was used for the heat source for ORC and the appropriate working fluids were searched among 26 candidate working fluids. The requirements to be a working fluid for ORC were reviewed and the cycle analysis for simple cycle was conducted with $75^{\circ}C$ and $35^{\circ}C$ at the turbine inlet and exit, respectively. R600, R601, toluene were best candidates if the system could work without leaking the working fluid. Next, R236ea, R245ca, R245fa were recommended because they are not inflammable working fluids as well as better efficiency.

Purpose: The purpose of this study was to compare health promoting behavior between working and non-working mothers with infants and toddlers, and to investigate factors affecting the mothers'health promoting behavior. Methods: This descriptive study was conducted through conveniently sampled 403 women who visited the child health clinics at two public health centers. The questionnaire included the Health Promoting Life Style Profile (HPLP) and a visual analogue scale for subjective health status. ANCOVA, one-way ANOVA, correlation analysis, and stepwise multiple regression were conducted using SPSS ver. 21. Results: Working mothers' average HPLP score ($2.30{\pm}0.37$) was higher than non-working mother's ($2.15{\pm}0.37$). The score of the physical activity subscale was lowest among the subscales and there was a difference between the two groups. Subjective mental health status was the only predictor of working mothers'health promoting behavior, and it explained 23.2% of variance in health promoting behavior. Subjective mental health status, education, and age were the predictors of non-working mothers' health promoting behavior and they explained 27.2% of variance in health promoting behavior. Conclusion: According to the findings, both working and non-working mothers' health promoting behaviors were low. To promote mothers' health, it is necessary to develop diverse community health promotion programs to support mothers.

This study is about the evaluation of the color arrangements of working clothes that are harmonized with working environment and assist in the protection of workers in industrial sites. This study attempted color arrangement design with the intention of giving order to the colors of working environment and working clothes so as to help improve the safety of work and the management aspects including human resource management, efficiency improvement, and the practice of business ethics. The study method consisted of literature research, empirical research, and evaluation research. The literature research performed theoretical examination about colors, industrial safety, and visibility. Three actual outdoor work sites in the machine industry were chosen and pictures were taken at 20-30 m from workers. The background colors of the work environment of each work site and the colors of the working clothes that were actually worn were analyzed through color values measured with a color-difference meter(CR-400). As a result, it was found that between value and chroma which affect visibility, color arrangement based on differences in chroma could be a greater influence than color arrangement based on differences in value. The results of this study could assist the integration of color schemes among working environment colors, people and working clothes by suggesting color arrangements with improved visibility that are applicable to the working clothes of domestic machine manufacturers that are playing a pivotal role in domestic industries and by presenting appropriate guidelines.

Third, the women who worked bad condition were not healthy. It was bad working condition that working hour was 11-12 per day and did not have holiday and monthly wage was 100,000-200,000 won. Fourth, the women who satisfied the job had higher health status than the women who dissatisfied the job. Fifth, it showed high health status that the women worked the place where health was well managed.

This study analyzed the relationship between stressful life events and state of mental health among middle class non working housewives and working housewives (104 pair) by age from June 5 to June 19, 1995 in seoul. The results of this study are as follows. 1. The degree of stressful life events was not statistically significant, but the degree working housewives group (Mean 1. 448) was higher than that of non-working housewives group (Mean 1.509). 2. The state of mental health showed statistically significant (p<. 01) the degree of non-working housewives group (Mean 7.36) was higher than that of working housewives (Mean 5.52). 3. The correlation between stressful life events and state of mental health showed natural in both non-Working housewives group (r=.497, p<.001) and working housewives (r=.532. p<.000), so increased stress is related to lower mental health. 4. The degree of stressful life events based on social psychological factor, showed statistically significant (p<.05) in the feeling of life, and the state of mental health was statistically significant in the part of feeling of life (p<.05) and subjective health state (p=.000)

This study investigated the general trends and differences in the working life of overseas Korean women. The subjects were 872 working Korean women over 20 years of age living abroad in America, China, and Russia Central Asia. The subjects completed a questionnaire on working life and the data were analyzed using SPSS. The working environment of Korean-American women was not stable. Many Korean-American women worked to help the home economy. They were paid by the hour, day and week. On the other hand, many Korean-Chinese women worked for self-achievement and usually for 8 hours a day. The working life of Korean women in Russia Central Asia was not good. They had a small income and worked to help the home economy. The first variables for changing their occupation were income and bonus. Despite their unstable working environment, overseas Korean women estimated their working life positively. They rated scores higher than the median on job satisfaction, business importance, duty ability, duty adaptation and family support. Job stress showed lower scores than the median. Korean women in Russia Central Asia showed lower scores on job satisfaction, family support, and work time flexibility than the other two groups.

This study aims at suggesting a series of process which envisions the colors of working clothes which is the working environment most adjacent to workers around the workers in the industrial spots. In order to do so, based on the photos of the workplaces, it was made an analysis on the relationship of between the colors of the workplaces as a background and the colors of the working clothes in the color characteristics. The color planning of the working clothes was suggested as a result of analyzing the colors and carried out the evaluation. The results are as follows; First, The colors of working environment and the colors of the working clothes were slightly different but in general, the spectrum was from mid value to low chroma. Secondly, the color modelsuggested was evaluated as a result, every question got a good review and especially, in the shipbuilding company, the working environment of which was the most unpleasant, every question was given a highest score of more than 4.50. The study would serve as the beneficial information for formulating the safer and more pleasant working environment in industrial workplaces as well as a basic material for the subsequent research on colors.

연안 경비함정의 선상근무 환경은 육상근무 환경에 비하여 매우 열악하여 선상근무 기피와 성원고령화의 원인이 되고 있다. 특히 선박내 소음은 난청과 같은 직업병을 유발시키는 원인이 된다. 따라서 안락한 선상근무 환경 및 거주 환경의 확보를 통하여 선상근무 피로도를 경감시키는 것이 필요하다. 본 연구에서는 먼저 선박내 소음 및 진동의 실선 계측을 통하여 선상근무 환경을 체계적으로 평가한다. 그리고 선상근무 환경의 평가 결과에 기초하여 선상근무 피로도 경감대책을 제안한다
