  • The purpose of this study was to investigate some influencing variables related to the management behavior on environmental preservation of housewives in Pusan. The subject of this study were 411 housewives and interviewed with a questionnaire. The data was analyzed by SPSS/PC+ Program for the frequency, mean, standard deviation, Cronbach's$\alpha$, t-test, F-test, Duncan's multiple range test and regression. The major result of this study were as follows : 1. The level of Environmental Management Knowledge was relatively high. The perceived level of environmental pollution was relatively high. The score of perception on water pollution was the highest. The level of management behavior on environmental preservation was relativity low. The score of management behavior on food pollution was the highest. 2.

  • The purpose of this study is to analyze the principal causes of increases in air temperature on platforms of railway station. We analyzed the distribution of air temperature on Shinkansen platforms at Station 'A' using Computational Fluid Dynamics (CFD). We focused on the factors that influence the temperature dynamics associated with heat generated by trains and station buildings and their effect on the ambient temperature on platforms. In the case of heat generated by trains, air temperature on Shinkansen platforms increased by 4 to 7 degrees compared to when trains generated no heat. When a 50-m high station building was located on the windward side of the platforms, air temperature on Platform X was 2 degrees higher than when the station buildings were absent. Air? temperature on platforms VII to IX increased progressively, and the maximum air temperature on platform VIII was 3 K higher than if station buildings were absent.

  • The purpose of this paper is to study the influence of hypersensitiveness in accident reports and usefulness on admission of atomic power generation. By the result of study we can look forward to understanding obstacles and promotion factors in constructing atomic power plants. The results of hypothesis testing can be summarized as follows: First, the hypothesis that hypersensitiveness in accident reports has a plus effect on reliability is accepted. Secondly, the hypothesis that hypersensitiveness in accident reports has a plus effect on anxiety is accepted. Thirdly, the hypothesis that reliability has a plus effect on anxiety is accepted. Fourthly, the hypothesis that reliability has a minus effect on receptiveness is accepted. Fifthly, the hypothesis that anxiety has a minus effect on receptiveness is accepted. Sixthly, the hypothesis that usefulness has a minus effect on necessity is accepted. Seventhly, the hypothesis that usefulness has a plus effect on receptiveness is rejected. Eighthly, the hypothesis that necessity has a minus effect on receptiveness is accepted.

  • Hybrid machine is based on hardware technologies of machine tool and software technologies of open architecture controller. In machining technology, combination technology of turning, milling, and grinding and in machining energy technology. combination of mechanical, electrical, and chemical technology are developed. This paper describes hybrid machine technology for combination of machining, on-machine measurement, on-machine CAM, and on-machine remote monitoring and control in open architecture controller environment. For on-machine measurement, non-contact measurement technology based on CAD information is developed. For on-machine CAM, interactive CAM program for automatic NC program generation and tool path simulation is developed. For generation on-machine remote monitoring and control, suitable interface method between web program and CNC is proposed. The developed hybrid machine technology is implemented in 3 axes milling machine for evaluation of operablity.

  • The purpose of this study was to evaluate the effect of basic needs and demographic variables of adult woman on the modesty and aethetics In the selection of clothes. The results of the study were as follows: 1. There are factors which have effect on variables of need. School careers have effect on physical need. Age, marriage status and household type have effect on safty need. Native community and household type have effect on self-esteem. School career, native community, household type and frequency of contact with mass media have effects on need of self-actualizing and native community has effect on the aesthetic need. 2. Physical bleed, self-esteem, self-actualization, safety need, fiequency of contact with mass media, age, native community and income have direct effect on the modesty of clothing. 3. Aethetic and self-actualization need, frequency of contact with mass media and income have direct effect on the aethetics of clothing.

  • The purpose of this research is to clarify the effect on personality of the child which may be infuenced by occupation and rearing attitude of the mother. Conclusion I. Mother with occupation does not give good effect on personality of the child, that is general Activity, Stability and Sociality. Conclusion II. Child attitude of mother effects greatly on personality of the child ; i.e. (a) good relationship between husband and wife makes good effects on the personality of the child ; and (b) rejecting attitude renders effects on the Stability of the child ; and (c) dominating attitude gives effects on Reflectiveness and Sociability of the child ; i.e. (d) overprotective attitude gives effect on Stability and Dominance of the child. Conclusion III. Whereas attitude of mother with occupation is dominaning, attitude of the mother without occupation is rejective. This difference in attitude gives effect on Reflectiveness, Dominance, Impulsiveness and Sociability of the child. Conclusion IV. Economic status of the famuly renders great effects on personality of the child, and this status effects Reflectiveness, Impulsiveness and Sociability.

  • On-off differential controller is one of the very important components which affect the system performance of the active solar thermal system. In this study, analyses were made regarding the influence of "on-off" setting temperature on the system efficiency and on the electrical consumption by circulation pump. This study was performed by experiment as well as the computer simulation using TRNSYS program. The simulation system was developed in this study was verified the its reliability by the experimental results. As a results, the turn off temperature(${\Delta}T_{off}$) is much more influence than the turn on temperature(${\Delta}T_{on}$) on the system efficiency. It is more clear and sensitivity in winter season. Finally the optimum on-off setting value and the system on-off pattern according to the several different kind of system was also represented.

  • The main purpose of this study is to examine the effect of ethical management on job performance. For the study, CEO's will, ethical management system and external ethical activity are selected as subordinate variables of ethical management. Therefore, the concrete purpose of this study are four issues: (1) to examine the effects of CEO's will on organizational trust,. (2) to examine the effect of ethical management system on organizational trust, (3) to examine the effects of external ethical activity on organizational trust, (4) to examine the effects of organizational trust on organizational performance. The sample for this empirical study is collected from 334 employees of 5 different companies executing ethical management. The results of analysis are as follows. First, there is a positive effect of CEO's will on organizational trust. Second, there is no effect of ethical management system on organizational trust. Third, there is a positive effect of external ethical activity on organizational trust. Last, there is a positive effect of organizational trust on organizational performance.

  • It was performed to find out the influence of duck meat on human serum cholesterol level. The duck meat was canned and given to the subjects. In case of human, the subject was divided into two groups; such as a male group and a female group. Blood sample was collected from each subject during feeding period and the serum cholesterol was determined by Bloor method. The results were as follows: 1. In the male group, serum cholesterol level was 187mg% on the initial day, 184mg% on the 3rd day, 181 mg% on the 6th day, and 178.8mg% on the 9th day after feeding period passed. 2. In the female group, serum cholesterol was 184mg% on the initial day, 181.4mg% on the 3rd day, 178.2mg% on the 6th day, and 173.8mg% on the 9th day after feeding period passed.
