This study investigated relationships between primary caregivers' life satisfaction and abuse mediated by children's life satisfaction. We included term panel data for 3 years (2013-2015) from the 4th year to the 6th year of 2,067 children in the first grade of elementary school of the Korean Youth and Youth Panel(KCYPS)(2015); in addition, three years' longitudinal panel data (2013-2015) were analyzed utilizing SPSS 18.0 and AMOS 22.0 to measure Latent Growth Model(LGM) term relationships between variables. Analysis results were as follows. First, the life satisfaction of the primary caregiver, the life satisfaction of the child, and abuse gradually decreased from the fourth grade to the sixth grade. Second, the initial status of primary caregivers' life satisfaction influenced the initial status of the children's life satisfaction, and the initial status and change in the abuse rate. Third, the rate of change of life satisfaction of the primary caregiver did not have a significant effect on the change in the abuse rate and the rate of change of life satisfaction of the child. The initial value of the life satisfaction of the child played a partial mediating role in the relationship between the initial value of the life satisfaction of the primary caregiver, initial value of the abuse, and abuse change rate. The results suggest that a program to improve the life satisfaction of the 4th grade elementary school should be developed and applied.

A house is basic unit of human being living space and it reflects an occupation, family relation, a life style and sense of value of resident. The purpose of this study was to research the continuity of traditional elements and contemporary change of Japanese houses by field study and literature research. The subject of this study was sixteen houses of Miyashiro, Saitama pref. in Japan. The results of this study are as follow as. First, the traditional elements of contemporary Japanese houses are tatami floor room, tsuzukima, zashiki, dokonoma, butsudan, amado. Second, the tatami is symbol of Japanese living space. Wasizus maintains a traditional characteristic, but it is developed and fixed properly change in contemporary life. Third, the traditional elements of Japanese houses are continuing in the modern houses, and they are continuously changed the feature from recreate. It can be a connection of a hereditary factor of residential culture. Four, the continuity of modern change and traditional element of the Japanese houses can be understood the change of the structural and spatial responding method to accommodates a life.

The purpose of this study ws6 to find out women's informationized conditions and their life changes. The subjects of this research were 482 women living in large and small-medium sized cities. The data analysis used average, pearson's correlation, one-way ANOVA and multiple regression by SAS/PC. The major findings were as follows: 1. Women's level of informationized conditions is under median in computer using and information technology. The effect of informatization is over median about improving the ability, recognizing from family and neighbor, achieving the occupation. The change of individual and family is under median except educational stimulus, life vitality and educational effect on the family. 2. The effect of informatization was influenced by ability of using computer, necessity and purpose of informatization. The change of individual was influenced by ability of using computer, purpose and effect of informatization and also the change of family was influenced by handicapped reason in information education and the effect of informatization.

This study empirically investigates the effect of self presentation on SNS to interpersonal relation and quality of life. Especially, we performed exploratory analysis that how SNS affect to quality of life and wether the change of interpersonal relation is mediating effect to quality of life and intention to use. And we also suggest that the capability of communication would be a moderator. In the results, firstly, the using SNS has significantly positive effect on the change of interpersonal relation. And it as mediation variable can positive impact on the relationship between the using SNS, quality of life, and Intention to use. In the moderating analysis, SNS users who responded higher communication capability have significantly more higher effect on the change of interpersonal relation and quality of life. Secondly, the change of interpersonal relation after use of SNS as a mediation variable serves to enhance the relationship between the use of SNS and the quality of life in the positive direction.

The development of industrial society brought about the highly-aged society, facilitated urbanization and nuclear families and changed conventional society and even the values. Also, development of Information Technology is represented digital technology makes general life-style of economy, society, culture and life. This paper offers there is sense to offer aged residing zero that equip amenities, safety, convenience considering enough request of aged by change of life-style. Hereupon, architecture enemy of aged residing, I wish to quote direction of unit planning of smart silver town that is intelligence style residing space that can correspond to various life-style that bring by information society by diagnosing change factor of residing space and internal and external study trend of smart groove that extract Needs of old age by change of special Quality and life-style and appears in digital environment.

This paper investigates an optimal consumption, portfolio, and life insurance strategies of a family when there is a borrowing constraint and risk aversion change at the time of death of the breadwinner. A CRRA utility is employed and by using the dynamic programming method, we obtain analytic expressions for the optimal strategies.

We studied the trend change of failure rate function and uncertainty of residual life function in terms of location of their trend change points. It is shown that the trend change of uncertainty of residual life takes place before the failure rate changes its trend. Like DIFR(IDFR) does not necessary implies IDMRL(DIMRL), we find the fact that DIFR(IDFR) does not always imply IDURL(DIURL) under certain conditions, through the exponentiated-weibull distribution.

The safety and the durability of the shock absorber as an automotive chassis part under the fatigue load can be predicted in this study. The fatigue life becomes constant from 0.5 to 0.75 at the change of load which is the amplitude load divided by average load. But its life is sharply decreased at the change of load from 0.75 to 1.5. The influence of fatigue life according to the change of load can be predicted by these results. As the value of maximum damage is 9.61 at the middle part of upper side on shock absorber under the concentrated load, there is the greatest possibility of destruction at this part. The spring of shock absorber becomes nearly the state of pure shear and the uniaxial or biaxial stress exists at the rest part of it under the fatigue load.

The more the lift environment eastern idea, culture, factory automation system and information technology complicates, the more the various human error brings about. It brings about all kind of accidents and occupational diseases. Also the death and sickness or injury by psychological stress among the human error has increased every year. Therefore this paper describes the Korean lift change unit model through statistical testing with the proposed life change unit factors on the married workers living the middle area. The proposed model can be simply used in order to minimize the industrial accident and human error in real fields. Finally, the result will be helpful for the better safety management.

The part of women was limited in a large family of the past and the benefit of a family was more valuable than the advantage of an individual. But social activity of the individual who is a member of the family is increased by the industrialization and rapid changes of society. As a result importance of the family is on the decrease in a society. All such phenomenons make new family types that we could not imagine at past and various life-style. This research proposes life-style of the near future and investigated by life-style stream process according to change members of the family with various documentary record. In conclusion, life-style of the near future is changed individualistic, rationalistic and material.
