Demographic variables have a great deal of impact on the utilization of health services. In this paper, the use of segmented polinomials is shown to be superior to the simple use of dummy variables and simple polinomials in explaining differences in health care utilization with respect to sex and age differences.

Accelerated ageing with low fertility is one of the most critical problems in Korea. Because of ageing via low fertility, Korea will face a serious demographic cliff. This research primarily focus on the analyzing the dynamics of the marginal ageing state and decreasing population especially in Eup and Myeon region. This study based on the system dynamics approaches for finding causal loop structure of marginal ageing and critical mass of population disappearing. The results of this study are summarized as follows. First, demographic marginalization trends have already begun in the Eups and Myons of Gun. Second, marginal aging speed in Eup/Myeon areas is causing an population disappearing in the near future. Third, critical mass of population disappearing will begin when the rate of marginal aging is exceed 82% after 2023.

The purpose of this study was; 1) to describe consumer preferences for wood~framed housing; 2) to determine factors which affect the preferences for housing environments in wood-framed housing by demographic, current housing, and wood-framed housing-related characteristics; and 3) to identify differences in preferred wood-framed housing related characteristics by demographic and current housing characteristics. From the visitors to a model wood-framed house in Seoul, Korea, 296 persons willing to live in a wood-framed house were selected as the sample for the study. Data were collected using a self-administered survey and analyzed by frequency distribution, factor analysis, chi-square test, t-test, and one-way analysis of variance procedures. The results of the study Indicated that among seven factors based on 32 housing characteristics, Factor 2 - "floor plan and Interior environment" was the major variable which showed significant difference by selected demographic characteristics. Regarding the differences in wood-framed housing related characteristics by demographic characteristics, age, gender, education, and family life cycle showed group differences. Also, housing type was the major current housing characteristic to provide significant group difference in preferred wood-framed housing characteristics.

The purpose of this study was to investigate family-demographic variables (sibling status, maternal attitude and demographic variables) affecting sibling sociability and peer sociability. Mothers and teachers of 291 kindergarten children were sampled. Specifically, 206 children of two-child families were studied by sibling status to investigate differences in sociability among siblings. Factor analysis, F-test, Pearson correlation, and multiple-analysis of variance were conducted. Sibling sociability and peer sociability were affected by sibling status. Maternal attitude and sibling sociability were positively correlated. The important family-demographic variables for both sibling sociability and peer sociability were maternal affective attitudes and sex of child.

Demographic transition drives changes in consumer demand for food products. This study examines how rising incomes and population trends affect spending on food purchased for home. The objective of this study is to characterize the relationships between selected socio-demographic factors and food selection among South Korean households. Panel data from Rural Development Administration (RDA) in South Korea in 2010 was used (n=971). Household food purchases were classified into one of the five food groups from Composition of Foods of RDA. Multiple regression analysis was used to analyze the effects of household size and income based on the expenditure share on each food group. All statistical analyses were performed using SAS/ PC version 9.3. Results show that household socio- demographic characteristics have a strong influence on food purchasing, with the purchase of vegetables and fruit, and processed food and pre-packaged being particularly sensitive.

In many surveys, one of the most important goals is to obtain reliable and valid responses from respondents. To achieve the goal, a researcher have to make efforts to protect respondents' confidentiality and to reduce the effects of social desirability on answers. The key question of this paper is whether the position of demographic questions have an effect on responses. Two types of questionnaires are considered: one puts the demographic questions at the beginning and the other does at the last. On both types, I asked only a small number of demographic questions which are considered as essential on analytic purposes. The results show no evidence of position effects when the risk to threat confidentiality was minimized.

This study investigated the relationship of demographic and psychological variables with job and family-related stress among 293 employed wives. We found that age, job types, working in weekend, and family cohesion significantly contributed to the explanation of job-related stress. We also found that job types, working in weekend, family adaptation, family cohesion, and employment motivation significantly contributed to explaining the variation of family-related stress. Job-related stress was more explained by demographic variables than psychological ones, whereas family-related stress was more explained by psychological variables than demographic ones. Practical implications of the current findings were discussed.

The purpose of this study was to investigate the tendency and characteristics of behavior problems in preschool children. The aim was to acquire basic information that could be used in diagnosis and intervention strategies. The target of this study were 823 preschoolers, the reporting on which was conducted through the responses of 81 teachers. Analysis consisted of partitioning behavioral problems by demographic variables in order to ascertain differences by age, sex, and cut-off score of the high risk group. Overall results indicate significant differences in behavioral problems according to socio-demographic variable. The conclusions of this study offer a foundation for diagnosis, intervention, and therapy for preschoolers with problem behaviors.

Team-members may have diverse backgrounds and characteristics and such diversity is getting increased in teams in terms of demographics(gender, age, and educations) and capabilities(knowledge, skills, and experiences). A meta-analysis of the last 40 years studies, however, concluded that diversity in teams does not have the consistent main effect on team performances. On the other hand, according to theories of selection and socialization, similarity in values, backgrounds, and experiences buttress the positive and effective working environment. Therefore, we conduct an empirical study in favor of similarity in work teams for the sake of team effectiveness. We investigated the importance of the similarity of team-members on IT team effectiveness. Two aspects of similarity, demographic and cognitive, were considered together. The shared mental model(SMM) was introduced as the representative construct for the cognitive similarity. We found that SMM is more important than the demographic similarities on team effectiveness.
