The objective of this research is to analyze how main social relation network of middle-aged women such as family, friends and neighbors, etc affects the preference for silver town. For this objective, structured questionnaires were distributed to 309 middle-aged women at the age of 40-59 years old living in Seoul and new cities of metropolitan area. Statistics such as ANOVA, Pearson Coefficient and Multiple Regression were adopted for statistical analysis. The main result of this research is as follows: First, housewives showed higher preference for silver town than people involved in other occupations. Second, though the relation of friends and neighbors among the social relation network of middle-aged women affected the preference for silver town, that of family did not affect significantly. The result of this research suggests that it is necessary to adopt policy considering the relation of friends and neighbors among the social relation network of middle-aged women so as to activate silver town.

According to aging society and social network society, the necessary of suitable alternative housing in the era has been increasing. The purpose of this research is to understand housing preference depended on the social relation of the elderly who lives in Beijing, China. The social relation was comprised of contact degree with child, contact degree with friend, contact degree with relative, degree of community participation, satisfaction with spouse and satisfaction with child. The housing preference was comprised of housing ownership, housing location, housing size and housing type. The survey was conducted on the elderly of 150 above fifties who lived in Beijing, China. For the result, the social relation was associated with the housing preference. Particularly, the relationship between the children was related to the housing ownership, housing location and housing size. The relationship between friends was related to the housing type. The level of community participation was related to the housing location. Social independence of the elderly, family cohesion, community attachment and adaption tendency were correlated with the housing preference. In conclusion, it was empirically identified that the social relation of the elderly had a relation with predicting housing preference.

A sequencing problem is to find an ordered sequence of some entities which maximizes (or minimize) the domain specific objective function. As some typical examples of sequencing problems, there are traveling salesman problem, job shop scheduling, flow shop scheduling, and so on. This paper introduces a new type of sequencing problems, named a sequencing problem with fuzzy preference relation, where a fuzzy preference relation is provided for the evaluation of the quality of sequences. It presents how such a problem can be formulated in terms of objective function. It also proposes a genetic algorithm applicable to such a sequencing problem.

The purpose of this study is to investigate the most rational method of grouping peers to understand the impact of peer relationship on individual development of elementary school students. For the study, students at a class of the 3rd year(male) and a class of the 4th(female) year at elementary schools in Busan and Ulsan were surveyed to see the differences between various methods of classification of peer relation subgroup on the basis of cooccurence of perception data and psychological preference data. Two questionnaires were used; a questionnaire of perception and a questionnaire of psychological preference. With the perception data, value of sharing relationship was applied to classify peer relation subgroup and with the psychological preference data, interest relationship was expanded to classify peer relation subgroup of more than third party relationship. The result of this study showed that in the case of girls, there was high congruency between the classifications of peer relation subgroup by perception data and by preference data, whereas in the case of boys, there was difference between the classifications of peer relation subgroup by perception data and by preference data, which implies that boys can form a peer group even if there is psychological difference among members but girls can form a peer group only when there is psychological preference among them. Such a result shows that there is difference between boys and girls in the process of forming peer relationship. It is suggested that comparison of fitness be made between classification of peer relation subgroup by a homeroom teacher, by perception data and by psychological preference for rational classification of peer relationship among male children.

This study is purposed to make sure of the Effects of Enterprise Trust on Relation-Continuing Intention and the Mediation Effects of Relation-Continuing Intention in the effects of Enterprise Trust on Customer Citizenship Behavior. Enterprise Trust consists of two elements(Enterprise Sincerity, Enterprise Ability), Customer Citizenship Behavior is made up of two elements(Guest Preference, Guest Cooperation) and Relation-Continuing Intention has one element itself. As a result, two things have been found. First, Enterprise Trust has a partly positive impact on Customer Citizenship Behavior. In details, both of two elements of Enterprise Trust have positive influences on Guest Preference, one element of Customer Citizenship Behavior, on the other hand, Enterprise Sincerity, one element of Enterprise Trust has a positive influence on Guest Preference, one element of Customer Citizenship Behavior but Enterprise Ability, the other element of Enterprise Trust, has no meaningful impact on Guest Preference. Second, Relation-Continuing Intention has a mediating effect between Enterprise Trust and Customer Citizenship Behavior. In details, Relation-Continuing Intention has a partial mediating role between Enterprise Sincerity and Guest Preference, between Enterprise Ability and Guest Preference and between Enterprise Sincerity and Guest Cooperation. However Relation-Continuing Intention has a full mediating role between Enterprise Ability and Guest Cooperation.

The main purpose of this research was to classify the contents of impulse buying of clothing products and to investigate how the impulse buying was influenced by fashion involvement, recognized brand preference, and impulsiveness. Samples were 238 college women in Seoul, Korea. The results of the research were as follows. 1. Four factors of impulse buying derived by factor analysis; F 1 'sensitive aspects of products stimulation'; F. 2 'utility aspects of products stimulation'; F. 3 'consumer situation stimulation'; F. 4 'marketing situation stimulation'. 2. Impulsiveness had a positive relation with impulse buying, fashion involvement, and recognized brand preference. Fashion involvement had a positive relation with recognized brand preference and impulse buying. 3. Impulse buying was influenced by fashion involvement and impulsiveness. The explanatory power of the 2 variables was 9.3%. 4. Fashion involvement was influenced by sensitive aspects of products stimulation, major, recognized brand preference, income, and grade. The explanatory power of the 5 variables was 23.7%. 5. Recognized brand preference was influenced by income, fashion involvement, and marketing situation stimulation. The explanatory power of the 3 variables was 11.2%.

The purpose of this study is to examine the difference of judge's gender and age groups in preference of S/S men's suit fabrics, and to analyze the relationship between the preference and the texture by gender and age group. For this study, 60 types of S/S men's suit fabrics were used with variously-composed fibers, such as wool, wool-blended, and PET, thickness, and weight. To evaluate the texture and the preference subjectively, nine ranks' semantic differential scale questions of 22 texture adjectives and preference of 4 apparel items were developed, Through the factor analysis, texture adjectives were classified into 7 categories: "stiffness," "elasticity," "bulkiness," "coolness," "smoothness," and "drapability." Depending on gender and age groups of judges, statistically significant differences on texture factors and the preference were observed. Especially, men under 30 years of age showed a higher grade of stiffness and a lower preference on pants than other groups. The relationship between the texture and the preference was different by gender and age group: Women evaluated a preference of men's suit fabrics in relation to stiffness and smoothness, whereas men did so in relation to stiffness, smoothness, coolness, and drapability. A young age group put more importance on drapability for preference of men's suit fabric.

For rational human value judgement and evaluation, provision of clear evaluation data, objective value judgement criteria, and properly generalized methods are required. For instance, this is true for software quality evaluation, and the measure of software quality and the weighting method of evaluation target directly affect final decisions. However it is not easy to find a generalized method for the software quality evaluation or product selection, because of its complex characteristics. In this paper, we apply the qualitative preference method based on quantitative belief functions to find a general weighing method for the software quality evaluation. In particular, the qualitative preference method, in which the differentiated preference expression is possible, is conceptually expanded for general applications in future. For this purpose, we hierarchically differentiate the strong preference relation from the weak preference relation, and show an example of quantification of software quality evaluation on different applications, by comparing the qualitative preference method with AHP. We believe that the application domain of this method is not limited to the software quality evaluation and it is very useful to apply this results to other SE areas, e.g., metric selection with different views and riority determination of practices to be assessed in the SPICE.

To examine closely the relations between food habits, food preferences and personality traits, 141 boys and 146 girls in the 5th and the 6th grade of primary school in Incheon were studied by questionaires. The results of this study were as follows: 1. In food habit scores, girls got 2.28/3.00 and boys got 2.24/3.00 which meant boys and girls had the similar food habits. 2. The higher were their activity, sociability, responsibility, reflectiveness, and superiority, the higher score they showed in food habits. 3. Meats, fats and processed foods had much to do with emotional stability, and those who belonged to high group in emotional stability high preference for them. But girls who had high preference for meats were low in emotional stability. 4. Fishes of which bones we can eat, and potatoes had relation to activity, and those who belonged to high group in activity showed high preference for them. 5. Vegetables and processed foods had relation to sociability. Those who belonged to high group in sociability showed high preference for vegetables, but those who belonged to middle group in sociability showed highest preference for processed foods. 6. Meats and potatoes had much to do with responsibility. Those who belonged to low group in responsibility showed high preference for them. 7. Those who belonged to the high group in emotional stability, and superiority showed the high preferene for foods respectively, and superiority showed the high preference for foods respectively.
