The purpose of this study was to examine children's consumption level and related factors in an effort to lay the foundation for teaching children to lead rational consumer life and for improving consumer welfare, as it's assumed in this study that children's consumption problems would affect themselves throughout their lives. This study specifically intended to find out (1) child consumer problems, (2) how children's consumption problems were affected by their demographic variables, (3) whether consumer-education experience made any differences to their consumption problems at school, home and society, and (4) what types of demographic and consumer-education variables exercised influence on consumption problems. The findings of this study were as follows： First, children investigated were found to have middle level of consumption problems. Purchasing goods scored the lowest, and using goods scored the highest among consumption problems. Second, it turned out that boys suffered more consumption problems than girls. The reason seemed that as boys generally have lower experience in consumption attitude. Third, as to the correlation of the children's consumption problems to their consumer-education experience, money management was significantly associated with the presence or absence of experience to learn at school how to manage and save allowances. Also, the experience of consumer education by parents made a significant difference. The children's consumer consciousness and attitude varied with their experience to receive consumer education from mass media.

In this paper, important design parameters for parallel kinematic robots are defined, paying special attention to machining errors which may cause kinematic errors at the end effector of a robot. The kinematic effects caused by each design parameter, as well as their upper/lower limits, are analyzed here. To do so, we have developed a novel software program to compute kinematic errors by considering its defined design parameters. With this program, roboticists designing parallel kinematic robots can understand the important design parameters for which upper/lower allowances have to be strictly controlled in the design process. This tactic can be used for the design of high-speed, parallel kinematic robots to reduce the design/manufacturing costs and increase kinematic precision.

Apparel purchase behaviors were investigated for the high school girls grouped by attitude toward fashion. Differences in attitudes toward fashion were also investigated among the groups determined by demographic characteristics. Data were collected by a self-administered questionnaire survey to 600 high school girls living in Seoul, and 480 were used for the data analysis. Cluster analysis, Chi-sguare analysis, ANOVA, and Duncan\`s multiple range test were used for data analysis. Technical school students and those who spending higher amount of monthly allowances showed favorable attitudes toward fashion. Based on the attitudes toward fashion, respondents were classified into 3 groups : fashion-oriented(32.3%), fashion-conformed(47.3%), and unconcerned(20.4%). Among the 3 groups, the Fashion-oriented tended to make purchase decision for clothing based on there own, or peer\`s opinions, to use personal sources for information search, to spend more money for clothing, and to consider design and brand names as the most important criteria when purchasing apparel products than the less fashion-oriented did. Among clothing styles popular to students, the most appropriately perceived for student wear were semi-formal style, and the least appropriate ones were wearing bold colored and patterned underwear for the purpose of showing out. Most of the popular styles among high school girls were perceived less than appropriate student\`s attire.

This study was conducted to develop a web expert system for nutrition counseling and menu management. This program manipulates a food, dish and menu and search database that has been developed. Clients can select a recommended general and therapeutic menu using this system. The web expert system can analyze nutrients in menus and compare nutrient contents of menus with Korean Recommended Dietary Allowances. It can access the food, dish and menu database. The expert menu database can insert, store and generate the synthetic information of age, sex, and therapeutic purpose of disease. With investigation and analysis of the client's needs, the menu planning program on the internet has been continuously developed. This system consists of the database that reaches to the food composition, the dishes and the menu. Clients can search food composition and conditional food based on nutrient name and amounts. This system is able to draw up the food with its order in dish. The menu planning can be organized and nutrients analysis can be compared with Korea Recommended Allowance. This system is able to read the nutrient composition of the each food, the dish and the menu. The results of analysis is presented quickly and accurately. Therefore it can be used by not only usual people but also dietitians and nutritionists who take charge of making a menu and experts in the field of food and nutrition. It is expected that the web expert system can be useful of nutrition education, nutrition counseling and expert menu management.

This study was designed to compare general characteristics and dietary habits between volunteers for a nutrition survey and non-volunteers using a questionnaire. Volunteers were recruited by advertising on the homepage of a university to assess nutritional status by examining dietary intake for three days and blood analysis. Non-volunteers were selected from some classes not related to nutrition. There were no significant differences in sex, monthly allowances, eating-out cost, drinking and exercise between the two groups, while the proportion of self-boarding was higher in the volunteer group than in the non-volunteer group, and smoking rate of volunteers was approximately 2.4 times lower than that of non-volunteers. Volunteers were less concerned about their diet than non-volunteers. No significant differences in concern about health, considering factors in their diet, self-evaluation of their diet, learning experience about nutrition, and vitamin/mineral supplement use were observed. The frequency and the place of eating-out for dinner were significantly different between the two groups. More proportions of volunteers tended to eat regularly and eat breakfast. Volunteers consumed seaweeds more frequently, and milk, fruits and fast foods less frequently than non-volunteers. Our results indicate that some characteristics and dietary habits of volunteers are different from those of non-volunteers. However, we could not show that volunteers were more interested in their diet and had desirable dietary habits than non-volunteers. Further research on the characteristics of volunteers who participate in nutrition survey may be helpful to interpret and generalize the survey results.

The purpose of this study is to examine the level of conspicuous consumption and resource-saving behavior in primary school students, and to discover the factors that influence these behaviors most strongly. The research was conducted in 2011 using a written questionnaires that were completed by 500 primary school students residing in Seoul, South Korea. The data was analyzed using statistical methods, including frequency, percentiles, means, standard deviation, Cronbach's coefficient, ANOVA, and hierarchical multiple linear regression analysis, using SPSS 18.0. As a result of these analyses, the average level of conspicuous consumption was found to be 2.65 relatively rational score. Next, it was shown that the conspicuous consumption of respondents differed significantly based on variables, such as allowances, family income, socialization process in childhood, family cohesion, and parental child rearing method. Finally, the greatest influences on respondent's resource-saving behavior was seen to be the child's socialization process in childhood, family cohesion, parental child rearing method, and conspicuous consumption. These variables must therefore all be considered when teaching primary school students and encouraging them to assume rational resource-saving habits in their daily lives.

The objectives of this study were to determine whether older Americans would provide valid energy intake information using a 24-hr recall method and to determine which characteristics were predictive of under-report of energy intake. We conducted 24-hour recalls on 83 male and 105 female community-dwelling older adults(66-87y) in the USA to assess energy(EI) and nutrient intakes. Basal metabolic rate(BMR) was calculated from age-and gender-specific equations of Schofield. Under-reporting was defined a priori as EI : BMR<0.9. Subjects volunteered demographic information, underwent depression and cognition exams, and completed a Level II Nutrition Risk Screen. Differences between under- and adequate-reporters were assessed using t-tests for characteristics and macro-nutrient profile. Stepwise regression analyses were used to predict under-reporting status. Under-reporting of EI occurred in 34% of the sample. Neither geriatric depression scale(GDS) score, nor self-reported weight loss were related to under-reporting. On average, under-reporters had higher body mass indices. The most significant variables for the main effect to predict the ratio of energy intake to estimated basal metabolic rate(EI : BMRest) were BMI and age. Using a standard cut-off of 76% of the recommended dietary allowances for Americans, under-reporters were consistently more likely to be classified as having inadequate nutrient, as well as energy, intakes.
