The purpose of this study was to propose theoretical-practical strategies of family-based intervention for the "Healthy Family-Support Center." The theoretical background used was an ecological approach, that is, taking viewpoints of client family's microsystems as well as those of exo- and macrosystems. This study raised several critical points in researching and developing family-based intervention programs. Based on a review of the literature, the study indicated why an ecological, family-based intervention model was a relevant alternative to investigate issues in family welfare and to deliver possible assistance and solutions for them.

The purpose of this study was to analyze difference in clothing preference based on the perceived body types. The objects of this study were to prepare for the establishment of a marketing strategy and alternative plan intended for users operating in a subdivided market, after analyzing the differences in clothing preference based on the perceived body types. The respondents comprised 192 female adults, who were residents in Busan. The questionnaire was composed of three sections: style, textile, and color of clothing. Data were analyzed by frequency, factor analysis, cluster analysis, discriminate analysis, and ANOVA. Cluster analysis was employed to identify groups of respondents based on the five delineated measure items. Based on the findings, three distinct groups were formed: thin, normal, and obese. The result of this study showed statistically significant differences among the three groups in terms of style, textile, and color of clothing, as well as in terms of demographic characteristics. Marketing and management implications for effectively targeting the segments are discussed.

The purpose of the study was to investigate the relationships of maternal attachment, social competence and interpersonal cognitive problem-solving skill. fifty-four children aged 5 and 6 years and their mothers were observed and videotaped in a strange situation. Children were interviewed in order to assess interpersonal cognitive problem solving skill. teachers rated children's social development using modified ISCE(Iowa Social Competency Scale : Preschool Forma). The results showed that there were significant relationships of maternal attachment, social competence and interpersonal cognitive problem-solving skill. children of the secure attachment to mothers were greater social activator, cooperative, alternative solution thought and consequential thought. In contrast, children of insecure attachment to mother were less social activator and cooperative, and more hypersensitive and apprehensive. Children's social competence was related to the interpersonal cognitive problem-solving skill.

The deteriorated apartments make a social problem in now a days. After all a new alternative plan for deteriorated apartments such as the remodelling concept must be considered. This study aims to survey the needs levels among residents in deteriorated apartments relating to remodelling. It might provide the basic data which could be used for the analysis of consumers in the future implementation of deteriorated remodelling projects. The analytical methods applied for this study were t-test, one-way ANOVA, post-hoc estimation(Scheff test) by the SPSS 10.1 for Windows program. The analysis of the need levels for the areas of remodelling, by the family characteristic variable, residence value viewpoint, and residence satisfaction level, indicated that the demand level for ‘equipment ’was the highest, followed by the order of ‘structure’ and ‘interior’. The need levels for ‘security’, ‘parking lot’, ‘public facilities in apartment block’, and ‘landscape’ were generally low but in the group of high income, the need levels were comparatively high.

The purpose of this study is to construct the family support system and suggest various policies for work-life balance to create the family-friendly society. For this purpose, this study showed the theoretical background for constitution of integrated family support system-community, government and business. Especially, this study emphasized that family-centered viewpoint to the policy is needed and that support for worklife balance not work-family balance should be enlarged. Various policies were suggested in three parts and the role of community was emphasized. Finally, this study presented the necessity of laws and committee for work-life balance and role of healthy family-support center for work-life balance.

The heat demand prediction is an essential issue in management of district heating system. Without an accurate prediction through the lead-time period, it might be impossible to make a rational decision on many issues such as heat production scheduling and heat exchange among the plants which are very critical for the district heating company. The heat demand varies with the temperature as well as the time nonlinearly. And the parametric specification of the heat demand model would cause a misspecification bias in prediction. A nonparametric model for the short-term heat demand prediction has been developed as an alternative to avoiding the misspecification error and tested with the actual data. The prediction errors are reasonably small enough to use the model to predict a few hour ahead heat demand.

This paper examines the alternative method to measure the state of overall economic activity. The macroeconomic variables, used for business cycle, take more than a month after a period for collection and aggregation. The electricity generation data is compiled in mechanical ways just after the period. Based on this fact, we develop the two stage estimation method for coincident economic indicators in order to detect the business cycle in an earlier period, using Stock-Watson's Dynamic Factor Model. Using monthly data from 1970 to 1999, it is found that the experimental coincidence economic indicators are well-fitted to data and also that the estimates of two stage estimation method have good explanatory power, equivalent to the experimental coincidence economic indicators. While the RMSE of coincidence economic indicators is found to be 1.27%, that of the experimental coincidence economic indicators is found to be 1.31% and that of the two stage estimation method is around 1.44%. If we take consideration into the fact that it measures the business cycle in one month earlier, we come to the conclusion that the two stage estimation is of great use.

The flat slab is well-known as a structural system to reduce the story height, so it is broadly used for recent building. However, the normal RC flat slab is not appropriate for the long span, and the quantity of reinforcement bar and concrete is raised. Recently, the post-tensioning system has been introduced and used widely as an alternative method. Nevertheless, in Korea, it is not used broadly due to lack of the understanding and field experience. Especially, the post-tensioning system is hesitated to use due to uncertainty of construction ability and economics. This paper will introduce applicability to site and economics of unbonded post-tensioning system through construction examples.
