Due to the rapid growth of publications, librarians have been facing the problems caused by the shortage of stack as well as the quality deterioration of library collections. This naturally disappointed the user communities and the present library activities are weak and inadequate. It seems to the author that one of the desirable actions in remedying this problems is to weed library collections properly and regulraly. The purpose of this study is to establish weeding criteria in library collections, particulary in the fields of polictical science, economics and law In order to establish weeding criteria, shelf-time period which is the length of time that a book remains on the shelf between the last two users of a volume, was measured by examining the book cards or date-due slips of circulating books and collections which remained in the stack. The results of this study are as follows: (1) In the fields of political science economics and law, the shelf-time periods of general materials in Korean for circulation was measured. (2) This study shows shelf-time periods that vary in different subject fields. (3) Combining the shelf-time periods of books in active circulation and the total collection including books which have never been circulated, the size of library holdings which may satisfy a certain percentage of the current circulation can be estimated.

The objective of this study was to provide fundamental data on somatotype for elderly women by classifying the somatotype and analysing the 3 characteristics of their somatotype. The subject were 368 women of 60~84 years old, they were analyzed indirect photography. To find out differences among the age groups, the 368 subjects were grouped into two age groups (Group 1 ; age 60 to 69, Group 2 ; aged 70 to 84). Data were analyzed using Factor analysis, Cluster analysis, duncan test and Analysis of variance. Through the factor analysis, 27 items from photometric measurements respectively. Cluster analysis was applied for classification of somatotype. The results of this study were as follows. 1. The characteristics of Elderly women's somatotype were bending of the upper-torso, fatness of the waist and abdomen, drooping of the bust and shoulder and hip. In addition, height, girth, depth and width items were decreased in their sizes respectively. 2. The characteristics of clusters were as follows. Type 1 was straight somatotype in which the plumb line through tragion, the bust depth and under bust depth region laterally. Type 2 was swayback somatotype in which the upper portion of protruding point on the back was bent forward but the lower portion of protruding point had a characteristics of turning over somatotype. Type 3 was bending somatotype. Namely, this type was shorter than average and below the average fatness. Generally, the lateral view silhouette of elderly women was the straight type and changed into bending type as the age increases.

The purpose of this study was to explore consumption status of scented textile products and to determine differences in consumption behaviors of scented textile products among subject groups separated by demographic (sex, age) and lifestyle (health concern, fashion involvement, innovativenss) characteristics. A total of 530 consumers who had used scented textile products participated in the web survey for the study. Consumer data were analyzed through descriptive statistics, chi-square test, factor analysis, t-test, ANOVA, and LSD test. In the results, the most often used products were small commodities, socks, bedding, and underwear of hub and flower scents. Consumers considered a product test as the most crucial information source and scent as the most significant decision making factor for purchase. Demographic and lifestyle group differences were found in some of the product types in use as well as in purchase behaviors (total spending amount, purchase venue, information source, considering factors when purchasing). The applicability of the study result to the theory of innovation adoption was discussed. Marketing implications were suggested based on the study results.

The issue of children′s education is the most important issue for all households in Korea. It is certain that the issue of private education for children is the first issue among household′s issues. This study is to recognize the current pictures of household primate education of Korean households. Also, whether the expenditure of private education effect the economic will-being of household. The data for this study was"the 3th Korean Labor Panal", conducted by Lobor in Korea. The sample was 1950 households from the panel data. The results of this study was as following: 1. The mean of monthly private education expenditure was 149273won for all households and 217,100won for households with high school students. 2. Almost 70% households had economic burden for private education expenditure. 0% households had no economic burden. 3. The factors of influencing the level of economic burden for private education were mother′s education level, mother′s job, the number of children, living location, monthly income, total asset of household′s. The factors of influencing the amount of monthly private education expenditure positively were living in 4. The economic well-being of household was analyzed by socio-economic variables, household′s financial variables, monthly private education expenditure, the level of economic burden of private education. The economic well-being were sub-categorized 4 divisions; the level of economic problem, the level of satisfaction for household′s income, the level of satisfaction for general living, the level of subject economic condition)

The purposes of this study were to examine: (1) the extent to which school-age children used computer games; (2) whether there were differences between children who played computer games to a greater extent and children who played computer games to a normal extent in their levels of depression, anxiety, self-esteem, and social anxiety; and (3) whether children's social withdrawal, aggression, and mothers' psychological control explained the extent of children's computer game playing. The subject were 270 children in the 6th grade. It was found that $55.6\%$ of the children were normal users, $39.3\%$ of the children were somewhat heavy users, and $5.2\%$ of the children were heavy users of computer games. There was a gender difference in the proportions of heavy computer game playing. That is, there were more heavy users among boys than among girls. It was also found that social withdrawal, aggression, and mothers' psychological control were significant predictors of the extent of children's computer game playing. That is, the levels of children's social withdrawal, aggression, and their perceptions of mothers' psychological control predicted the degree to which children played computer games.

This paper investigates the extent of global and regional integration in East Asia using stock price index as a measure of economic performance. We employ a structural VAR model to separate the underlying shocks into "global", "regional" and "country-specific" shocks. The estimation results show that country-specific shocks still play a dominant role in East Asia although their role appears to have declined over time, especially after the 1997 financial crisis. Global and regional shocks are responsible for small but increasing shares of stock price fluctuations in all countries. The results indicate that the stock markets in East Asia remain dissimilar and are subject to asymmetric shocks in comparison to European countries.

The subject of the ongoing research work is to analyze the composite action of the structural elements of composite slabs with profiled steel decking by experimental and numerical studies. The mechanical and frictional interlocks result in a complex behaviour and failure under horizontal shear action. This is why the design characteristics can be determined only by standardized experiments. The aim of the current research is to develop a computational method which can predict the behaviour of embossed mechanical bond under shear actions, in order to derive the design characteristics of composite slabs with profiled steel decking. In the first phase of the research a novel experimental analysis is completed on an individual concrete encased embossment of steel strip under shear action. The experimental behaviour modes and failure mechanisms are determined. In parallel with the tests a finite element model is developed to follow the ultimate behaviour of this type of embossment, assuming that the phenomenon is governed by the failure of the steel part. The model is verified and applied to analyse the effect of embossment's parameters on the behaviour. In the extended investigation different friction coefficients, plate thicknesses, heights and the size effects are studied. On the basis of the results the tendencies of the ultimate behaviour and resistance by the studied embossment's characteristics are concluded.

This study investigated the relationships between inter-cultural experience and socio-psychological adjustment to the current life among children who have refilmed from living abroad. The subject of research consisted of 102 boys and 110 girls from fourth grade through sixth grade who returned to their home country after living in a foreign correlation Data were collected from 5 elementary schools in Seoul. Descriptive statistics, t-tests, correlation analysis and regression were used for data analysis. The results of children's social-psychological adjustment were represented by 3 categories: school/friend relationship, stress/strain and language/learning. The following are the summarized results; First, girl students were more likely to adapt to school/friend relationships in Korea and had lower stress/strain than boys. Second, the children having shorter period of residence in foreign county, lower adaptation ability to different culture and extrovert personality showed higher socio-psychological adjustments after returning to Korea. Third, the adjustment to school/friends was influenced by period of residency in the foreign county, the experience of different culture, and extrovert personality. The experience of different culture and extrovert personality effected stress/strain, and the adjustments to language/learning were influenced only by the ewperiecne of different culture. Lastly, the experience of different culture was the most important variable influencing all 3 categories of socio-psychological adjustments.
