This study examines the wearing conditions of working clothes according to the working environment and working processes at machinery, automobile, shipbuilding industry sites. It also investigates the relationship between the wearing sense of working clothes and the overall comfort according to work processes. The hazardous working environment was high in the order of the shipbuilding industry, machinery, and automobiles. The findings on the harmful overall work environmental factors were the noise, heavy dust, and noxious fumes, respectively. In general, the satisfaction with the wearing performance of working clothes was low especially with regard to sweat absorbency, sweat permeability, body protection and covering, and the work motion suitability. In respect of the correlation between the overall comfort and the wearing sense of working clothes, the satisfaction was decreased in the order of movement comfort, sensual comfort, and physiological comfort.

Objectives: In order to prepare measures to enhance construction workers' satisfaction with their working environment, the effects of working conditions and the mediating effects of safety and health information on workers' satisfaction with their working environment in the construction industry have been studied. The results of this study can be used as basic data for further studies in this field. Method: Data on 1,361 male construction workers from the 5th Korea Working Condition Survey (KWCS) were used for this study. The effects of working conditions were analyzed using SPSS 25.0 and the mediating effects of health and safety information were analyzed with SPSS PROCESS macro using the bootstrap method. Results: The safety and health management system and the self-determination of break time had a statistically significant positive effect on satisfaction with the working environment. Chemical and ergonomic risk factors had a statistically significant negative effect on satisfaction with the working environment. The provision of safety and health information, the mediating variable, had a statistically significant positive effect on satisfaction with the working environment. Therefore, it had a mediating effect between working conditions and satisfaction with the working environment. Conclusion: In order to enhance construction workers' satisfaction with their working environment, the above results suggest that the safety and health management system should be well established; self-determination of break times should be guaranteed; and chemical and ergonomic risk factors should be controlled. In addition, workers should be provided with necessary health and safety information related to their work. This study will be useful if these findings are used as basic data in further studies in related fields.

In this study, methyl methacrylate (MMA) - modified polymer mortar(MMPM) was developed and its setting shrinkage and working life properties were surveyed. In order to study the setting shrinkage, setting shrinkage test for the 24 batches were also conducted with taking the MMA monomer content to the UP resin and the mixed content of shrinkage reducing agent(SRA) as variables. Furthermore, in order to study the working life measured gel time, working time, setting time of MMPM and binder. Experimental resurts show that the workability remarkably improved as the mixed MMA content increased. The working life was proportional to MEKPO content and was shorted. also, showed high interrelationship of binder gel time and MMPM working life. Setting shrinkage markedly reduced as the content of MMA and the SRA increased.

In this paper, we analyzed the relationship between employment stability, wage level, welfare system, working condition, job satisfaction and organizational commitment in order to find out ways to develop and competitiveness of the nano-convergence industries. Through this study, we conducted the possibility of deriving organizational commitment by job satisfaction which is given through employment stability, wage level, welfare system, and working condition for continuing their work life. In order to find relationships between each concepts, we used a multiple regression analysis with job satisfaction and commitment as dependent variable and employment stability, wage level, welfare system, and working condition as independent variables. Through this study, it was expected to increase the organizational commitment through the job satisfaction of the employees if a changing method of employees management is centered on some tasks suggested for the sound working condition and efficient utilization policies.

A fast and inexpensive approximate analysis method to predict power output characteristics of the Stilting engines in a preliminary design stage was investigated. In basic equations proposed by Walker, typical temperatures of working fluids in expansion and compression spaces were treated as those of working fluids in heater and cooler respectively. While the temperature of working fluid in the expansion space was actually lower than that of working fluid in the heater, the temperature of working fluid in the compression space was higher than that of working fluids in the cooler. In this paper, the working fluid temperature of expansion space was treated as lower than the heater temperature and that of compression space was treated as higher than the cooler temperature. Also, according to them, the power output characteristics of the Stirling engine were evaluated with respect to the GPU-3 and 4-215 Stilting engines. The following conclusions were drawn from the analysis. 1. Using the available experimental data from the GPU-3 Stirling engine, it was shown that the approximate analysis predicts the brake power with a maximum error of 19 percent at 1, 000rpm and with a minimum error of 3 percent at 2, 000rpm. 2. The approximate analysis data which for the GPU-3 Stirling engine were much closer to the experimental data than those of adiabatic 2nd order and 3rd order analysis within 1, 500rpm to 2, 500rpm. 3. The approximate analysis data which for the GPU-3 and 4-215 Stilting engines were much closer to the experimental data than those of the Beal number analysis.

The purpose of this study is to draw up a plan for improving working conditions of distant water fishing vessel crew in order to revitalize the declining distant water fishing industry. Land-based employment has increased as the result of industrialization, which in turn created shortage in marine crew supply for distant water fishing vessels. Pressure on increasing wages for sea farers is put on the industry for this reason, making the labour market in the distant water fishing industry tougher and tighter. Multiple issues have yet to be addressed for distant water fishing vessel crew. They suffer from excessive work compared to other industries. Crew management is another issue, as sea farers face poor labour conditions, working on board vessels in a collective way where no autonomous actions are allowed. Other issues include unqualified crew supply, increasing ratio of labour costs for crew to sales, and intensified implications of labour unions, which are as well making crew supply difficult as a whole. To this end, more well-qualified workers should take part in production operations in the distant water fishery. Both wage increase and working condition improvement should be achieved in order to strengthen motivation towards qualified sea farers. Sustainable crew supply can be achieved when working environments, gender-based working conditions, welfare are prioritized and improved as a whole.

The saying likely as "In the rapidly-changing outside management environment, the light-weighted body only able to survive" means the 'lightness' in working space, reducing expenditure for immovable property and unnecessary facility, and also means the flexibility of facility which is ready to cope promptly with the approaching situation. For such reason, as many enterprises do not support an individual workstation for each person but by introduction of sharing system, also reducing the area for working space, they have made the immovable property expense per person curtailed. Though the reduction of the immovable property expense that subsequently gained by merely decreasing of working space brings a remarkable effect of retrenchment, there is also a worrying opinion that because of the narrowed working space than before, or by disappearing of private space, a possible non-productive effect which let working enthusiasm falls down might be brought. By practicing such investigating method, at the first stage survey, the Satisfaction of non-territorial and territorial office user and the order of required improvement are figured out, also arranged the appraisal items as 6 factors in total, and all of the factors were being influenced to the entire satisfaction in statistically meaningful level.

The study was aimed to develop men's working pants patterns through the computerized 3-D virtual clothing simulation system and to verify the effects of the 3-D simulated outfit by comparing it to the images of the actual outfits. The average body measurements of South Korean men aged between 30 and 39 used for the simulation in order to generate a 3-D virtual model and to realize outfits of men's working pants for the workers in the heavy industry in South Korea. And also the preliminary questionnaire survey results on certain aspects of the working pants such as type, detailed design preference and discomforting parts were taken into consideration. Both the simulated and real images of the developed working pants were compared in terms of the ease amount according to parts of the working pants, the position of seam lines, the appearance of darts and pleats, and the effects of the fabric surface according to expertise panels' subjective 5-point scale evaluation. The results throughout the study were (1) the basic working pants item worn by subject workers were the straight one pleated pants. The most discomforting parts of the working pants were in the order of body rise, thigh, hip, waist, pants hems and knee girth. (2) the drafting factors of pants patterns differed by the men's body features, which was related to the allocation of suppression amounts between waist and hip girths into darts and hip curve amounts on the waist line level of the pants. (3) the similarity of the virtually simulated and real images of men's working pants resulted in an average of 4.5 to the ease of appearance, 4.6 to the seam lines, 4.1 to the fabric surface effects in a 5-point scale, which means that the two were highly alike.

Objective : We proposed fundmental rules of prospective on legal and institutional position and role of Korean medicine doctors working at public health center. Methods : By the result of this research on the current situation, the grade and allowance given to the Korean medicine doctors working at public health center were different every self-governing body. Results : The reason the Korean Medicine Doctor can't serve as a regular order of 5th grade is that the 'The Enforcement Regulation about Administrative Organization and the Standard of Pixed Number of person of Self-Governing Body(지방자치단체의 행정기구와 정원기준등에 관한 규정 시행규칙)' prescribes the number of regular order of 5th grade is regulated within 7% among the number of regular order officials. But not appointing to office as the regular order of 5th grade infringes on the Constitution, the highest law. The reason the Korean Medicine Doctors can't be appointed to office as the regular order officials by the self-governing body is that 'The Enforcement Order of the Law of Preservation of good health of Local Area(지역보건법시행령)' prescribes the Korean Medicine Doctors are not indispensable to Public Health Center. But in fact, the Korean Medicine Doctors can execute many kinds of work such as medical examination or instructing house nursing. Conclusion : The Korean Medicine Doctors working at Public Health Center serve at low positions as daily use or common use, not receiving a regular order. All laws including the Constitution(헌법), the Medical Services Law(의료법), the Law of Preservation of good health of Local Area(지역보건법), the National Public Service Law(국가공무원법), the Local Public Service Law(지방공무원법) and the Law of Higher Education Law(고등교육법) describe that the Korean Medicine Doctors and the Western Medicine Doctors are equal to their position and right.
