This study designed to explore the patterns of housing life-styles and the characteristics of apartment housing residents and to examine the relationships between housing life-styles and the characteristics of apartment-housing residents. The data for this study was collected by questionnaires administered to 278 homemakers living in apartment housing over 20s pyong(66$m^2$) in the Kwangju area. The major findings of this study can be summarized as follows; 1. Housing life-styles were grouped into 9 sub-categories : the Anbang-centered, the dining-centered, the pursuit of conspicuosness and conformity, orientation to change, the pursuit of orderliness, the pursuit of decoration, orientation to community, pursuit of individuality and the orientation to a natural environment. 2. Housing life-styles were significantly different according to age, educational background, and employment status of homemakers, occupation of the primary income provider, family-life cycle stage, total household income, and housing size.

This study explores the effects of rural migrant characteristics and conjugal communication on life satisfaction of baby boomer rural migrants. A total of 205 Korean baby boomers, who are living in rural areas in the year of 2013 that had migrated from cities back in 2003 with their families, were analyzed. Their age ranged from 49 to 57 years. The statistical methods used for data analysis were descriptive statistics, t-test, and hierarchical regression analysis, with SPSS Win 20.0 program. The results of this study are summarized as follows: the reasons these baby boomers chose a rural lifestyle were 'for life after retirement,' 'because rural life is good,' 'for health reasons,' and 'for chosen profession.' The level of conjugal communication (M=3.69) and life satisfaction (M=3.23) were higher than average (M=3.0). The variables influencing life satisfaction of baby boomer rural migrants were 'increased property size,' 'better conjugal communication,' 'better health condition,' 'lower levels of money,' and 'length of time spent farming.' Furthermore, in terms of life satisfaction, the relative contributions of these variables are as follows: general characteristics 20%, rural migrant characteristics 10%, and the level of conjugal communication 6%. These results show that conjugal communication is a very important variable, as well as a rural migrant characteristic when it comes to life satisfaction of these baby boomers. Therefore, to improve life satisfaction of baby boomer rural migrants, support programs need to focus on both farming and conjugal relationships.

Purpose: The purpose of this study is to evaluate the life of the capsule, which is a core part of the heat storage cooling system. This paper will develop a life test mode that can reproduce environment conditions through the analysis of capsule shrinkage and expansion characteristics. Methods: In order to determine the life test mode of the capsule, this paper analyzed the case of field failures and analyzed the deformation characteristics according to the pressure fluctuation of the capsule. The method to find out whether the field failure and deformation analysis results are consistent is the testing with the construction of the repetition pressure test equipment and the thermal cycle test to reproduce the freezing and thawing characteristics. Results: In this study, failure mode analysis and analysis of freezing and thawing characteristics regarding to the capsule positions were completed. Based on this test & analysis results, this paper have been able to determine the main parameters for determining the life test mode, the freezing and thawing time. Conclusion: Determining the lifetime mode of the capsule can be used to improve the life and performance of the thermal storage system.

The purpose of this study is to investigate children's emotional problems (attention problem, aggression, somatic symptom, social withdrawal, depression) and to examine the relationship between children's emotional problems with family characteristics (parent education, parent job, family income), life-styles (gaming times, TV times, sleep time). The sample was 2,140 collections of second grade children and their parents who participated in Korea Youth Panel Survey on 2011. We analyzed the data which were collected by means of questionnaires and the data were analyzed with t -test, ANOVA, Pearson correlation analysis, and regression analysis with SPSS ver. 19.0. The results were summarized as follows. The level of children's emotional problem was relatively low on average. There is a significant difference in the children's emotional problems according to family characteristics and life-styles. There was a relationship between children's emotional problems (attention problem, aggression, somatic symptom, social withdrawal, depression) and life-styles (gaming times, TV times). The significant factors influencing the children's emotional problems are connected with father's education, mother's job, family income, family characteristics, gaming time and TV time of life style. It is noted that parent education level was an important factor for children's attention problem and aggression. Amongst children's life-styles, gaming time and TV time are negative factors for social withdrawal and depression.

This study examined the psychological aspects of a single life with particular focus on the personality ＆ emotional characteristics, the social ＆ behavioral characteristics, marriage, happiness, and sex of singles. The sample consisted of 160 single male and female aged 30 to 49. The results of the questionnaire survey showed that the singles tended to be self-centered, especially when they did not have a plan to get married, and that most of the singles in the 30s wanted to have a friend of the other sex. In the view of marriage, young, male singles were more likely to form a family than old, female singles. Also, female singles, bereaved or divorced, were shown to have fear about marriage and negative attitudes toward marriage more than male, never-married singles did. Regarding the extent of happiness, old, female (rather than young, male) singles tended to be more satisfied with a single life. Besides, old, religious singles were less likely to feel lonely than young, unreligious singles. In addition, it appeared that college-graduated singles had rather liberal view on sex although singles generally showed rather conservative toward sex in this study. Therefore, the findings reveal that singles were self-centered, social, positive view on marriage, somewhat happy of a single life, and having a conservative attitude about sex. Further understanding of a single life in modem society is needed in future studies.

As the steam temperature of fossil power plant boiler is increasing, the use of 9Cr-1Mo high alloy material is prevalent and it is needed to investigate the characteristics of low cycle fatigue for high alloy and austenite stainless steel that has used up to recently. As a result of test, in 9Cr-1Mo high alloy steel, the relation of strain and fatigue life is non-linear and the crack mode of low cycle fatigue is brittle but in the austenite stainless steel, that of strain and fatigue life is linear and the crack mode of low cycle fatigue is ductile. Comparing the fatigue life between high alloy and austenite stainless steel, there is no consistent characteristics as to strains. But the fatigue life of 9Cr-1Mo steel is longer by 25% than that of STS304 stainless steel in the relatively low, 0.3% strain. In the other strain, the fatigue life of two materials is similar.

This study has a purpose to analyze trajectories of life satisfaction of the elderly after their retirement and how the characteristics of individual, retirement and family relationship have an effect on the life satisfaction. This study has investigated the Korean elderly, who had been retired, using the data from three waves(1st wave(2005)~3rd wave(2009) of the Korean Retirement and Income Panel(KReIS). Data analysis has been used to identify the predictors of the intercept and slope related to the life satisfaction after retirement, focusing the trajectories of the life satisfaction after retirement and individual characteristics, retirement characteristics and family relationship with application of the growth curve model by Amos 20.0. First, the intercept of the life satisfaction after retirement was somewhat below average. Life satisfaction averagely increased little by little from 1st wave to 3rd wave. Second, by conducting the conditional growth curve model, the study revealed that the intercept of the life satisfaction after retirement is high on individual characteristics(sex, educational level, income, health status) and in retirement characteristics(voluntary retirement) and satisfaction with family relationship and married life). Furthermore, health status, voluntary retirement, and satisfaction with family relationship asserted the meaningful variables in the slope of life satisfaction after retirement.

The aim of this research is to investigate the demographic characteristics of the purchase tendencies and shopping trends amongst female golfers and how these are influenced by their life style and to analyse their selection criteria for purchases of golf-related items. The research methodology was through the use of questionnaires, completed by female golfers in Gyeongnam. The results are as follows: life style trends of male golfers were analysed to be categorized into one of the following: the shopping-addicted, fashion-conscious, rationalist and family oriented spenders. The characteristics of these categories are described as one of the following: utilitarian-complacent, rationalist, self-worshipping, inconsiderate. The demographic characteristics showed notable variations only in age differences. The obtained results show that the influences of the variables are minimal and there was no notable correlation. Significant differences were observed from one life style group to another, in selection criteria for purchase, which mainly depended on style, design, colour, pattern, designer-label, co-ordinated looks, similarity, ease of maintenance and functionality. Comparisons were made between the previously categorized life-style-groups and notable differences were present in such characteristics as ostentatious, trendy, aesthetically pleasing and functional.
