본 연구는 이동도서관에서 집중적으로 많이 이용되는 도서의 특성을 조사하고 이용자의 유형을 조사하였다. 본 연구를 통하여 얻은 결론은 도서 대출 분포는 브랫포드의 분산법칙, 지프의 법칙같은 현상이 존재한다는 것이다. 즉, 대출 횟수의 약 80%가 장서의 약 30%이내에서 오며 도서 대출 경향에서 수확 체감 현상이 나타났다. 그리고, 도서의 내용, 출판 후 경과 년수, 대출 경과 일수, 인구학적 특성이 장서의 이용에 영향을 준다. 즉, 아동 도서, 한국 소설, 외국 소설 순으로 많이 대출되며 출판 후 경과년수가 5-6년 이내의 도서가 핵심 도서이며 출판 후 경과년수가 짧은 도서일수록 대출횟수가 많다. 그러나, 아동 도서, 한국 소설, 외국 소설이 대출 횟수는 많지만 도서 이용가치수명은 기타 도서의 1/2에 불과하다. 대출 도서의 대부분(80%)은 6주이내에 최종 대출되며 이용자는 여자가 30, 40대가, 가정주부가, 고졸이상이 많이 이용한다.

In spite of the usefulness of migration statistics in spatially understanding social processes and identifying social effects of spatial processes, services and analyses of the statistics have been restricted due to the complexity of their data structure. In addition, flow mapping functionality which is a useful method to explore and visualize the migration statistics has yet to be fully represented in modern GIS applications. Given this, the purpose of this research is to demonstrate the possibility of flow mapping and the exploratory spatial analysis of the migration statistics in a Web GIS environment. For this, the characteristics of the statistics were examined from database, GIS, and cartographic perspectives. Then, O-D structure of the migration statistics was converted to spatial data appropriate to f low mapping based on the characteristics. The interface of Web GIS is specialized the migration statistics and provides exploratory visualization by allowing dynamic interactions such as spatial focusing and attribute filtering.

The purpose of this study is to investigate the effect of cultural and demographic factors (age and gender) on the perception of product information. The theoretical frameworks of interest in the current study are two cultural models: Hofstede's individualism (IND) and Hall's context. In examining the research questions, this research discovers that the cultural changes are occurring for the Korean young generation, even though Korean students are still within collectivistic culture. The correlation results suggest that the younger students have the higher individualism values compared to the older students. Using two multiple regression analyses (one set for high-context condition and one set for low-context condition), the study finds that cultural value and age significantly predicts the perception of product information in high-context (visual) condition. However, there is no significant difference in the perception of product information between male and female.

This study examines the sampling bias that may have resulted from the large number of missing observations. Despite well-designed and reliable sampling procedures, the observed sample values in DSFH(Demographic Survey on Changes in Family and Household Structure, Japan) included many missing observations. The head administerd survey method of DSFH resulted in a large number of missing observations regarding characteristics of elderly non-head parents and their children. In addition, the response probability of a particular item in DSFH significantly differs by characteristics of elderly parents and their children. Furthermore, missing observations of many items occurred simultaneously. This complex pattern of missing observations critically limits the ability to produce an unbiased analysis. First, the large number of missing observations is likely to cause a misleading estimate of the standard error. Even worse, the possible dependency of missing observations on their latent values is likely to produce biased estimates of covariates. Two models are employed to solve the possible inference biases. First, EM algorithm is used to infer the missing values based on the knowledge of the association between the observed values and other covariates. Second, a selection model was employed given the suspicion that the probability of missing observations of proximity depends on its unobserved outcome.

The present study applied Bayley Scales of Infant Development to Infants with High Risk to investigate the effects of determinants such as variables related to demographic variable, prenatal and perinatal and postpartal environments, and developmental indices in infancy. First, mental and motor development index were high in infants whose mothers had high in education, mothers had not had a disease during the pregnancy, mothers had not taken medicine during the pregnancy. Second, mental and motor development index were high in infants who had used an oxygen inhaler, incubator, and in infants who had been given a timely birth. Third, mental and motor development index were higher in infants whose mumbling and the initial speaking was normal than in infants whose development was late.

Stress is a common risk factor for health and is associated with the endocrine gland and immune system. Studies on the association between stress and biochemical factors have been conducted worldwide, but studies on the association have been rare in South Korea. Therefore, the aims of this study are to analyze the relationship of stress with demographic information and biochemical factors for domestic adults and derive risk factors for stress. For data analysis, stress and normal groups were analyzed using binary logistic regression. In both men and women, age and average daily sleep time during the weekday were highly associated with stress, and the depression score (Patient Health Questionnaire-9) was also highly related with stress. In women, white blood cell levels were highly associated with stress, and in men, red blood cell levels were highly related with stress. These findings will contribute to the prevention of stress and the national health in the future.

The Construction Technology Information System collects, processes, and provides the public with free of charge 16 types of construction technology-related texts or index information, such as construction standards, construction practices, and construction reports, required at construction sites to enhance domestic construction technology. This study judged that user satisfaction could be increased if the budget was allocated first to the most effective construction technology information DB establishment. For each type of construction technology information, the level of satisfaction felt by the population for the quantity provided and the value of use according to the acquisition and utilization of information were investigated. Reliability between independent variables and dependent variables through a multiple regression analysis process to identify how the demographic characteristics of the population affect user satisfaction and the factors that affect the use value of information for each type of construction technology information. and the correlation was analyzed. The correlation between the demographic characteristics of respondents and users' satisfaction with the provided quantity was generally low, but construction experience, age, etc. were found to have an effect on satisfaction with the provided quantity. In particular, among the demographic measurement items of respondents, the more construction experience they had, the higher their satisfaction level with the quantity provided of low-level technical standards, and it was analyzed that older age had an impact on satisfaction with the quantity provided for small and medium-sized business support information.

The purpose of this study is to examine how the commonly known profile of public library users was described, by reviewing the literature published in the United States before the 1990s, when information environment of the public has been drastically changed. The profile of users as the socio-economically advantaged, active participants, and communication elites, has little changed since Berelson's study in the 1940s. Continuing research on users, however, are still needed to better understand their needs and behavior, facing the change since the 1990s.
