The purposes of this study were to classify consumer types and to analyze purchase behavior depending on food safety attitudes related to the Fukushima nuclear accident. Based on the consumer survey data, factor analysis and cluster analysis were done to classify consumer types. Applying factor analysis, six factors with a total variance of 73.4% were extracted from 22 basic variables. The 6 factors were termed 'anxiety from ingesting agricultural and fishery products after the nuclear accident', 'importance of food safety when purchasing food', 'reduced rate of purchases of agricultural and fishery products after the accident', 'importance of food prices', 'socio-demographic characteristics' and 'family composition'. Using cluster analysis, consumers were classified into 5 types using the factor scores of 6 factors. The main results are as follows. For every consumer type, the anxiety about imported agricultural and fishery products was higher than that for domestic products after the nuclear accident. The food safety attitudes of consumers were mainly formed by the socio-demographic characteristics. Consumer types with high-education and high-income responded flexibly to the food safety concerning the accident; especially, the consumer type with a high-income and kids under 19 responded very reasonably to the accident. However, consumer types with a low-income and aged over 50 or less than 30 years were the least responsive to the accident, mainly due to financial restrictions. Thus, we suggest some food safety strategies and policy implications based on consumer type for food safety after the accident.

Recently, the waterproofing performance of high-voltage connectors in automotive vehicles has attracted increased interest. In this study, an optimal cross-sectional shape was derived to obtain uniform contact pressure and strain by considering stress relaxation problems caused by initial tension when mounting a seal. A high strain of 52.1 was distributed in the round region, owing to excessive initial tension. The finite element method (FEM) analysis indicated that the strain corresponding to the optimal initial tensile was 11. We adopted six design factors to optimize the seal cross-section and three factors as the main design factors. An orthogonal arrangement table was prepared using Minitab. FEM analyses of 16 study models were conducted to determine the optimized model. The contact pressure of the optimization model is the most evenly distributed while satisfying the waterproof performance of 0.47 MPa. Compared to the initial model, the difference in strain decreases from 35.5% to 19.6%. Finally, the derived cross-sectional shape can reduce the strain of the round region by 33.8% and the differences in the contact pressure at the upper and lower surfaces by 42% and 76%, respectively.

The hakgil is the important disease in the oriental medicine historically. In the preseant time also this disease continually appear all over the world. So purpose of this study is that consider the symptoms and pathogenesis of hakgil(瘧疾) with the point of view of oriental medicine. And in this study, the results are summarized as the followings. 1. The symptos of hakgil(瘧疾). 1) Rigor and heat spasm : The main symptoms of hakgil is the severe and periodical rigor and heat spasm. Generally the rigor first appear and later the heat spasm appear. According to the first and last, severe and weak, the hakgil is classified to hanhak(寒瘧), onhak(溫瘧), danhak(癉瘧), binhak(牝瘧). 2) The regulation of the time of spasm : The spasm occour in the same time daily or one time in two days, three days or several days. And the spasm time is regulary in day or night. 3) The term between the spasm and next one become later or faster. It can be decided that the becoming worse and better in the disease with the signs. 4) The seasonal property Generally the hakgil appear in summer and early autumn. 5) The other kind of hakgil there are five-organ hakgil(五臟瘧), six-kyung hakgil(六經瘧), janghak(瘴瘧), kuihak(鬼瘧), six-gi hakgil(六氣瘧), damhak(痰瘧), sikhak(食瘧), and so on. 6) The pulse condition of the hakgil is chiefly hyun(弦). 2. The pathogenesis of the hakgil 1) The cause of the hakgil The causes of the hakgil first are the seo(暑) or heat(熱) that make the problem in the cycle of five phases(五行). In the consequence, il open the hole of skin so that the pathogenic factors easily invade the humanbody and at the same time the pathogenic factor in the inside easily come out, that make the spasm. In the second time the pathogenic factor of yin(陰) - wind(風), cold(寒), water(水) invade through the opened skin to combine with the factor in the inside. Such condition make the hakgil and the accessory spasm. 2)The pathogenesis of hakgil(瘧疾) (1) The rigor and heat spasm of hakgil(瘧疾) appear because in summer the human body don't accomplish a task of summer because of hot weather or heat, so in autumn the ki(氣) of human body separate into yin(陰) and yang(陽), and the skin of human body is weaken so the saki(邪氣: pathogenic factors) is easily come into the human body. At this time the circulation of ki(氣) is obstructed, so the jungki(精氣: vital substance) apply to straighten the circulation of ki(氣), if the jungki(精氣: vital substance) help the yin(陰) the rigor spasm appear in the opposit direction the jungki(精氣: vital substance) help the yang(陽) the heat spasm appear. (2) The period of circulation of ki(氣) and jungki(精氣: vital substance) is one day, so the general period of spasm of hakgil(瘧疾) is one day, But if the saki(邪氣: pathogenic factors) come into the human body deeply, the jungki(精氣: vital substance) cannot apply 10 straighten the circulation of ki(氣) every day so the period of spasm become longer.

The purpose of this study was to identify the categories and contents of the cognitive inferences of both men and women regarding the style and color of clothing. The study was conducted by survey method, using open-ended questions. The data were collected from 420 male/female university students and analyzed by the qualitative method. The main results are as follows: First, cognitive inferences are formed from stereotypes that fall into six categories--appearance, personality, background, behavior, situation, and reaction. Second, there are some differentiations in these stereotypes depending on clothing style and color. Specifically, the amount of exposure represented in the clothing style is a salient features, one that shows situational attribution. Third, the strength of stereotype differs depending on the sex of perceivers: women indicate a stronger tendency to stereotype-based on clothing-than do men. In conclusion, each of cognitive inferences occurs between wearer and the actual perceiver. Stereotypes are important determining factors fDr making cognitive inferences.

The main concept of social carrying capacity is based on the principle that 'there are limits to the number of users a given recreation site can accommodate in order to provide quality of recreation experience'. The quality of the experience is revealed as user's satisfaction and perceived crowding. In this respect, studies of social carrying capacity have been frequently conducted by measuring perceived crowding and satisfaction. The purpose of this study is to identify the variables affecting perceived crowding, and causality bet-ween satisfaction and perceived crowding. Four hundred seventy six visitors were selected at Naejangsan National park on peak day of autumn excursion through on-site survey. The collected data were applied by factor analysis for categorizing the research variables, and multiple regression for finding the causality among variables. The study results are follows. The expectation of crowding, as a normative variable for perceived crowding, are categorized by three factors; circulation, user facility, and landscape. The circulation factor is the most powerful affecting perceived crowding among three factor. The landscape factor, however, do not have statistical significance on perceived crowding. The causality between satisfaction and perceived crowding is found. Although this relation is significant in statistics, magnitude of the coefficient is very small. It might be interpreted that satisfaction cannot be predicted simply from a user's perception of crowding, but a multi-dimensional concept such as adaptation and coping behavior.
