Modern art is getting more comprehensive and diversified regardless of genre in many forms due to the pluralism and anti-aesthetic trend of the time which is impacted by post modernism. This atmosphere is also applied to fashion illustration which creates synergy effect in cooperation with many different genres. This study selected Matisse' paper cut-out as the subject which would reflect the minimalism and ionism of modern plasticity. By taking this as the motive for fashion illustration, I made seven illustration works with the subject of minimalism of form and color. The conclusion of this study is as following. First, Matisse's paper cut out has controlled plasticity related to the modern ionism and it well fits the modern trend and sensibility which is appropriate for motive of fashion illustration. Second, by upgrading the technique of Matisse' paper cut-out in a modern way such as combination of hand drawing and computer graphic using Photoshop, I was able to make originative and creative illustration works with background and patterns that were closely connected with each other. Third, applying the fashion illustration to other various products is being well received now and I made my illustrations that could lead to follow up studies to apply the fashion illustration to other different products. Matisse' paper cut-our has forms, colors and patterns that can contain both commercial and artistic value. Therefore it is quite feasible for follow up research to apply into many different areas.

The purpose of this study is to investigate the level of role stress perceived by employed housewives working in sales departments, and further, to devise coping strategies that can help reduce stress resulting from their multiple roles The sample of this study consisted of married women who were working in sales departments, who have at least one child, and who live in the greater Seoul metropolitan area. A total of 343 out of 450 originally distributed questionnaires were used for the analysis in this study. The findings of the study are: 1 The housewives in sales departments felt stress most severely in their role as a mother. Next were the roles as a wife, housewife, daughter, daughter-in-law, and working woman, in that order. 2. It appeared that age and the motive for employment affected the overall level of role stress among housewives. The two variables (age and the motive for employment) explained about 23% of the variance. The younger they were the higher was the level of role stress. Also, if they were working for an economic reason (to support the family), they tended to be more stressed out. The results of this study could be utilized as baseline data for policy-making, consultation, and development of educational programs for housewives working in sales departments, an area that has hardly been explored.

The purpose of this study was to collect baseline data for women＇s needs for social education, in order to eventually contribute to improving the quality of women's social education. In the needs survey, information on the motive to participate in social education programs, obstacles to participation, and program preferences was collected. The data were then analyzed by women＇s socio-demographic characteristics. Survey participants were married women between the ages of twenty to fifty, who were sampled from Seoul, six metropolitan areas, and nine provinces. For the final analysis, 1,026 survey forms were used. The motive for participating in women＇s social education programs was examined by each category. Overall, the participants showed the highest level in educational achievement motif. The motivations for lifestyle change, self-realization, and social accomplishment were also high and at a similar level. As for obstacles to participation, social obstacle received the highest rate, followed by family obstacle and personal reasons. As for the type of social education programs, home management programs were the most preferred, followed by psychological education, family education, leisure activity programs, physical education, and social education programs.

This study aimed to examine the water consumption of urban households according to pro-environmental attitude for environmental protection. In contrast to preview studies, this study purposed to include various related independent variables, motive to environmental behavior, in special, in the model, and suggest informative data for research, education and strategies related to environmental protection. The data were from 665 housewives living in five urban areas. For the analysis of data, frequencies, means, percentages, GLM analysis, DMR test and Chi-square test were used. The main results of this study were as follows; 1. The respondents held high pro-environmental attitude that pro-environmental behaviors are important to protect environment. The pro-environmental attitude among the respondents were statistically different from the independent variables : spouse's occupation, living area, help of housekeeper, knowledge about environmental protection, convenience to check water consumption, and perception of voluntary conservative behavior among neighborhood 2. There were great difference on water consumption among respondents. The significant independent variables to have effects on water consumption were different between water consumption per person and higher/lower average water consumption. The relationships of pro-environmental attitude and motive to pro-environmental behavior with two water consumption as dependent variables were unique. Also, living areas and knowledge about environment protection were consistently important to explain the difference of water consumption.

In order to measure steel corrosion in mortar by a transient electro-magnetic (TEM) Method, the development of the sensors have been studied. The sensors were made of enamelled wire with diameter of 0.25mm and Acril. The sensor configuration was used as a coincident loop type. The secondary electro motive force(EMF) was measured with SIROTEM III. The accelerator was equipped with the SIROTEM III. The accelerator permits the transmitter to turn off approximately 10~15 times faster than normal. The high resolution time series used for very shallow or high resistivity investigation was selected. The steels were embedded in mortar which were made from sand : cement : water ratio of 2 : 1: 0.5. The mortar specimen was 50cm long, 20cm wide and 10cm thick. To investigate steel corrosion in mortar, the sensors used were with 2$\times$2$cm^2$(3, 6, 9$\Omega$), 3$\times$3$cm^2$(3, 6, 9$\Omega$) and 6$\times$6$cm^2$(3, 6, 9$\Omega$). The obtained result obtained showed that the sensor 8(6$\times$6$cm^2$, 6$\Omega$) was the proper sensor for the measurement of steel corrosion in mortar.

This paper presents the over-modulation strategy and indirect vector control drive of NPC type PWM inverter. NPC inverter has three level phase voltage output.It can perform in high voltage through assembling switching components. It has less harmonics and surge voltage stress at motor terminals than the 2 level inverter in same switching frequency through 3 level voltage. The conventional railway vehicle has used the vector control to MI=0.907 and the slip-frequency control from MI=0.907 to six-step mode. The slip-frequency control has bad motive power and slow torque control response. But vector control has good motive power and can instant torque control. In this paper, output voltage is controlled linearly from linear region to six-step mode by using over-modulation strategy. And NPC inverter is used.

In this study, we have dealt with a design characteristic of outer-rotor type permanent magnet (PM) motor applied for Engine Cooling Fan (ECF). When we design a motor with structure like this type, it is required as a requisite to consider 3-Dimensional (3-D) effect by implementing a non-linear Finite Element Analysis (FEA) due to a yoke-ceiling, which is perpendicular to the axis of rotation. We have analyzed identical models under three different conditions. The analysis has been performed through a non-linear 2-Dimensional (2-D) and 3-D FEA. Finally, the results have been compared with Back Electro-Motive Force (BEMF) value of actual motor model. As a result, a yoke-ceiling function as an additional flux path and the operating point on B-H curve of rotor material is shifted to non-saturation region relatively. Accordingly, magnetic flux linkage can be increased and motor size can be decreased under same input condition to satisfy ECF specification, such as torque.

The paper aims to investigate the impacts of long-term savings motives on fostering household participation and contribution to savings mechanisms in rural Vietnam. The paper is organized in five parts: introduction, data description, methodology, empirical results, and conclusion. The quantitative methodology is employed and three simultaneous estimation methods, including instrumental variable model, two-step model, and Heckman model are used to test these impacts as well as the robustness of results. In each model, the paper examines the impacts of independent factors on both household participation and household contribution to savings mechanisms. Two sets of independent variables: long-term savings motives (profit-making investment, accumulation for big expenditure, providing for old age, and cost of educations) and control variables (dependency rate, number of people in household, and household wealth) are in each model. A set of dataset of 2,314 households for analysis is obtained from household survey in rural Vietnam. Robust statistical findings indicate that profit-making investment emerged to be the strongest motive fostering household participation to savings mechanisms while other long-term savings motives have little or no impact on fostering household participation to savings mechanisms. In addition, education investment encourages household contribution to savings mechanisms in rural Vietnam.
