This study was conducted to investigate the relationship between general characteristics and the eating-out behaviors of 643 male/female industrial workers. The results of the study was summarized as follows. 1. The frequency rate of eating-out was higher for male than female, college graduates than high school graduates, high income earner than low income earner, and unmarried than married(p<0.05). 2. Average cost for eating-out was higher for male than female, for high educated and high income earner than low educated person. Age, married or not, personal health conditions and BMI, however, didn't make any difference in the average cost for eating-out. 3. Reasons fur eating-out was very different due to gender, age, degree of education income rate, married or not, BMI(p<0.05) but basically eating-out was due to get together with friends or colleagues. Also, people who thought they were not in good health answered that they did not eat-out in any conditions. Overweighted people ate out more often than normal or under-weighted people. 4. The method in gathering information about eating-out was different according to the level of education and whether married or not. On the other hand, gender, age, income rate, personal health condition and BMI did not make a big difference in its method. However, most People who Participated in the survey gathered information from people around them, such as friends/colleagues. 5. Taste was the most important factor in deciding the actual eating-out restaurant among the respondents and gender, age, level of education, married or not also made significant differences (p<0.05). 6. Besides personal health conditions and BMI, all the general characteristics including age made significant differences in selecting the most frequently visited restaurant. 7. Besides the personal health conditions, the transportation vehicle was different due to gender, age, level of education, income rate, married or not and BMI. As seen from the results, the eating-out behaviors mostly differed due to general characteristics. In order to searching for a new eating-out market, the general characteristics and the trend of the target customers has to be analyzed to activate the eating-out industry. In addition the need for highly nutritional food with low calorific value has to be emphasized along with the taste.

The purposes of this study were to segment female consumers on the basis of their clothing image preference, and to investigate the clothing purchasing behaviors of each segmented market. The research method was a questionnaire survey and participants were 700 women aged from 20's to 60's in Daejeon and Chungnam province. The questionnaire consisted of items for clothing image preference, clothing purchasing behaviors and the participants' demographic characteristics. The data were analyzed by Cronbach's ${\alpha}$, factor analysis, cluster analysis, ${\chi}^2$ test, ANOVA and the Scheff$\'{e}$ test. The results were as follows. Female consumers were divided into 7 types(sophisticated, natural, characteristic, elegant, active, feminine, and neat type) by clothing image preference. The 7 segmented market groups differed in many ways in terms of demographic characteristics and various clothing purchasing behaviors(clothing selection criteria, purchasing motives, fashion information sources, places of purchase, shopping frequency, and quantity and cost of purchases). The results of this study supported the view that clothing image preference can be a useful and effective variable for female market segmentation.

This study was to investigate the consumption pattern, behaviors, and motivational attitudes related to fruit and vegetables. Data were collected from 344 mothers whose children were attending an elementary school and a middle school in Kimcheon. The average vegetable expenses were under 10,000 won per week. The frequency of purchasing vegetables was 2-3 times a week. Housewives usually bought the vegetables at local markets and grand shopping centers. As for buying vegetables, housewives considered the organic vegetables, preference, price, and nutrition in order. In the family, the vegetables were favored by husbands most and by sons least. The average fruit expenses were under 10,000 won per week. The frequency of purchasing fruit was 2-3 times a week. Housewives usually bought the fruit at local markets and grand shopping centers. As for buying fruit, housewives considered preference, price, and nutrition in order. The fruit were favored by all members most and by husbands least. Housewives identified barriers to increasing vegetables and fruit consumption, including preference for other foods, lack of availability, cost, and time and effort to prepare. Several implications for nutrition interventions were suggested. First, a key motivation for these women was eating healthy food when they are pregnant, suggesting a persuasive appeal to use in interventions. Second, review of the women's current behaviors led to an identification of four specific behaviors that had the most potential for increasing overall consumption. Finally, the findings suggested ways in which nutrition interventions could address each of the barriers identified.

This study was conducted to provide basic data and insight into behaviors that result in increased continuous sales and competitiveness. This was done by examining the effect of personal involvement on customer satisfaction and trust, the effect of customer satisfaction on switching cost and loyalty, the effect of trust on switching cost and loyalty and by analyzing the indirect effect of trust and loyalty to personal involvement on switching cost and loyalty of the patrons of casual dining restaurants. In order to achieve the goals of the study, a hypothesis and structural equation were proposed based on preceding research and the proposed model was analyzed using LISREL 8.30 to prove the hypothesis and better understand the interactions between the cause and effect. The results were as follows: Six proposed hypothesis were chosen and the indirect effect was verified. In other words, customers' personal involvement was shown to have an effect on trust and devotion and satisfaction influenced switching cost and loyalty. Trust had an effect on switching cost and loyalty and by analyzing the indirect effect the customers' personal involvement was shown to affect the switching cost and loyalty through satisfaction and trust. The result of this analysis provides clues to better understand the eating-out behavior of customers and proves that personal involvement, satisfaction, trust, switching cost and loyalty are directly and indirectly related.

This paper proposes the concept and the general framework of the risk-based seismic design. Because earthquakes and the behaviors of structures are very unpredictable, probabilistic seismic design methods have been proposed after deterministic design methods. Considering these changes, we can find that the important point of seismic design is not the structural behavior itself, but the consequence of structural behavior under possible earthquakes. Risk-based seismic design can tell these consequences under any earthquakes. In this paper, structural confidences are considered by using fragility curve, and risk is modeled by failure probability and consequence-property damage cost, casualty cost.

For the personal robot to serve humans as a companion in our daily life, it is obviously important that the robot should have a long-term relationship to users. In this paper, we introduce a simple idea on how to make the long-term relationship by using just low-cost and simple robots. We also describe the robotic artificial creature system to implement this idea. The artificial creature robots respond not only physical environment changes but also the logical information changes in the virtual world such as the Web. They consist of a control robot and several simple robots, which show users various group behaviors. Users have a relationship with them by observing these behaviors, rather than interacting with them. We separate physical robots and software applications in order that artificial creature robots can have more various behaviors made by various software applications. Finally, we implemented the system using a robot simulator to show some example cases.

The purpose of this study is searching for hemodialysis nursing bahaviors by hemodialysis room nurses and analyzing them. Then, it estimates hemodialysis nursing costs and obtains basic data for development of proper nursing costs. First, it searched for hemodialysis nursing behaviors at a tertiary hospital hemodialysis room in Seoul and classified them. After the content validity was verified by 6 experts, Tool of hemodialysis nursing behaviors was developed. patients who recived hemodialysis were classified by dialysis patient classification tool. The searcher observed hemodialysis nursing behaviors applied to classified patients per 5 minutes. Then hemodialysis nursing hours spent to classified patients were calculated respectively. The direct expenditures and indirect expenditures were estimated. Ultimately, hemodialysis nursing costs were estimated. The results of the study were as follows ; 1. hemodialysis nursing behaviors were grouped by the same knowledge and skills. then, the content validity of them was verified by evaluation tool of nursing intervention classification by expert groups. They consisted of 9 hemodialysis activity domains and 71 hemodialysis nursing behaviors. The predialysis activity domain included 15 nursing behaviors, the activity domain of start-dialysis included 12 nursing behaviors, the activity domain of during- dialysis included 9 nursing behaviors, the activity domain of finish-dialysis included 5 nursing behaviors, the activity domain of after-dialysis included 5 nursing behaviors, the nursing documentation & undertaking and transfering included 5 nursing behaviors, the supply, drug, equipment & environment management activity domain included 7 nursing behaviors, the patient emotional support & education activity domain included 4 nursing behaviors, the emergency activity domain included 9 nursing behaviors. 2. The acute hemodialysis nursing hours were 106.42 minutes per a dialysis and the chroni hemodialysis nursing hours were 72.23 minutes per a dialysis. 3. The direct expenditure was 11.971 won per hour and indirect expenditure was 288won. 4. Finally, the cost of acute hemodialysis was 21,745 won and that of chronic hemodialysis was 14,759 won. By search of hemodialysis nursing behaviors, they will be used as hemodialysis nursing care standard and will be tended toward high qualitative care. Estimation of hemodialysis nursing costs will be used as fundamental data for development of proper nursing costs.
