The purpose of this study was to analyse the factors that influence marital conflicts and family life statisfaction, and to predict the future stage of establishment family and extending family, bsed on the theretical model by system approach. For this pourpose, 336 couples of urban households in Seoul were selected. The data were analysed through statistical methods such as, Frequency, percentile, T-test, F-test, ANOVA, Pearson's correlation analysis. The results were as follow : The Martial Conflict and family life satisfaction of surveyed couples were above middle level. It had significantly differences according to family life cycle, husband and wife's educationed levels, husband and wife's occupations, and family income. And Family life satisfaction had significantly differences according to marital conflict. The marital conflict is higher, life satisfaction is lower. In this study, it were appeared that the amount of marital conflict and life satisfaction had differences according to life cycle stages, husband and wife's educational level, husband and wife occupations, and family income, and so that the conflict of phsycho-social system was more affected on family life satisfaction that of managerial system. Such results were indicated that the birth of children was the critical family event affecting on family life satisfaction on and the marital conflict. But the conflict by family's given resources and situational differences also as an environment affection on the family system.

With the competitive pressure and the development of information and communication technology, many organizations have introduced various kinds of enterprise-wide systems like enterprise resource planning (ERP) systems as strategic tools for the purpose of improving organizational performance. Despite their promised strategic benefits, however, their implementation has suffered from a high failure rate and difficulty in realizing the anticipated benefits. Previous studies have indicated that one of the most critical failure reasons is the lack of knowledge sharing and utilization across organizations. As a consequence, many information systems (IS) researchers have paid attention to examining the effect of absorptive capacity closely associated with knowledge sharing and transferring on IS usage performance. ERP systems implementation involves changes not only in systems but also in processes and other social dimensions, which can be related to organizational citizenship behavior (OCB) requiring appropriate communications and interactions among organizational members. A lack of communications and interactions due to a lack of OCB might lead to weak absorptive capacity and thus negatively influence knowledge sharing across organizations, because OCB facilitates a successful collaboration among functional units and positively impacts individual's attitude toward radical organizational change. With this motivation, this study has two research objectives. First, it introduces and tests a theoretical model accounting for the relationships among performance of ERP system usage, absorptive capacity, and OCB. Second, it examines a mediating role of absorptive capacity between OCB and performance of EPR system usage. Theoretical and practical implications of the study ware discussed, along with its limitations.

The adjustment of negative emotions in later life is related to the quality of life and life satisfaction. any studies have examined how to control the negative emotions in related to physical, psychological, and social relationships. As the digital media and contents positively influence elder's mental and somatic well-being, it is significant to examine this problem from IT usage, especially the selection of digital contents. This study validated the theoretical study through a qualitative exploratory study comprising both negative emotions and the selection of digital contents, and empirically tested the proposed research model on the older people. The result shows the pattern of linkages between the grief of loss and the pursuit of digital contents. Loss from being parted by death and loss of relations was positively related to the information seeking contents. Economical loss and loss of physical functions was positively related to the innovation seeking contents. Loss of physical functions and Loss from being parted by death was positively related to the emotion seeking contents. And economic loss and loss of relations was positively related to the entertainment seeking contents.

The purpose of this study is to overview domestic and foreign trends in the study of the landscape evaluation through new framework of landscape evaluation studies. 108 studies on the landscape evaluation are summarized and categorized into theoretical studies, verification of theories, development of evaluation methods and applications in physical planning. Major theories in the landscape evaluation came from the psycho-physics, the evolutionary theory ann the cultural-learning theory, and were verified and applied into physical planning. Early experimental researches on landscape evaluation, based on psycho-physics, were focused on relatively simple responses to landscapes. But many studies have been gradually related to the evolutionary theory and the cultural learning theory, emphasizing biological and cultural effects on landscape evaluation. Especially, Appleton's Prospect-Refuge theory' and Kaplans' 'Information Processing model' have very strong influence in landscape evaluation. Relatively there have been many application researches in Korea, which tells there have been strong needs to solve pending practical problems caused by the rapid economic and social growth for several decades. Almost of applications in physical planning are focused on physical features of landscapes, but for more comprehensive landscape evaluation, many other factors such as cognitive and sociocultural variables should be integrated into the whole evaluation system. As a result of reviewing of landscape evaluation studies, I found the overall domestic and foreign trends and the necessity of more research on the applications in physical planning. Because this study mainly focused on academic researches, for more appropriate landscape evaluation and management there should be more practical researches including various approaches.

Many Koreans have been interested in health functional foods(HHFs). Use of health functional foods is growing rapidly. This study aims to identify the determinants of HFFs use focusing on health related factors. The subjects were 24,626 samples from Korea Health Panel in 2008. The subjects were divided into two group: under the 20 years old and 20 old and over. The logistic regression model was used to examine influence of health-related factors on use of HFFs for each group. About thirty percent of the subjects have used HFFs. The larger family size, higher education level of parents, more stable economic status and chronic diseases were positively related to use more HFFs in younger 20 years old. Higher education level, more stable economic status, chronic diseases were more likely to use HFFs in 20 years of age and over. Health related factors such as disability, chronic diseases, admission, and physician visit affect the use of HFFs in both groups. We confirmed that health related factors as well as socio-demographic and economic factors affect use of HFFs. In-depth knowledge about relationship between health related factors and HFFs is required.

IT consulting is becoming a norm rather than exception in this age of smart work and information revolution. As IT consulting is one of the knowledge intensive services requiring high credence on both sides, maintaining a good trustful relationship is critical in sustenance of strategic partnership between business firms and IT service firms. Trust is known to be one of the salient constructs in service relationships. In this study, building from the social psychology literature, trust is conceptualized as two dimensions : cognitive and affective trust. Using two dimensions of trust as mediators, a research model is constructed for IT consulting specific context : relationship continuance intention as the dependent construct while expertise, service performance, reputation, relationship satisfaction and value similarity as antecedents of cognitive and affective trust. 145 data points were collected through a survey of IT service client project managers retrospectively asking their experience with IT consultants. Findings suggest that cognitive trust is associated with perceived level of expertise and service performance while affective trust with relationship satisfaction and value similarity, respectively. Interestingly, the paths from reputation are found to be statistically insignificant towards both dimensions of trust, indicating IT service context would be more practically outcome oriented than any other professional service context. Also, cognitive trust seems to maintain stronger influence on relationship continuance intention as anticipated. Implications and limitations are discussed at the end.

For business purposes, it is important to identify diffusion power users, a group of users who have big influence on other users in diffusing content. In this paper, we use the independent cascade model for determining diffusion power users, and to do so, we need a method for calculating the assimilation probability between users. This paper proposes the concepts of user delivery power and a way to quantifying the value of this. User delivery power is used to compute the assimilation probability with user content power. We analyze the proposed method by comparing its performance with those of existing methods through experiments using a real blog network data.

Stress at work and in the family is a very common issue in our society that generates many health-related problems. During recent years, numerous studies have sought to define the term stress, raising many contradictions that various authors have studied. Other authors have attempted to establish some criteria, in subjective and not very quantitative ways, in an attempt to reduce and even to eliminate stressors and their effects at work and in the family context. The purpose of this study was to quantify so-called cushioning variables, such as control, social support, home/work life conciliation, and even sports and leisure activities, with the purpose of, as much as possible, reducing the negative effects of stress, which seriously affects the health of workers. The study employs data from the Fifth European Working Conditions Survey, in which nearly 44,000 interviewees from 34 countries in the European Union participated. We constructed a probabilistic model based on a Bayesian network, using variables from both the workplace and the family, the aforementioned cushioning variables, as well as the variable stress. If action is taken on the above variables, then the probabilities of suffering high levels of stress may be reduced. Such action may improve the quality of life of people at work and in the family.

Purpose: This study was performed to investigate the factors influencing health behavior. Method: Data used in this study was drawn from a 2001 National Health survey done by Korea Institute for Health and Social Affairs. Number of samples were 5,085 people between age 20 years and 69 years in whole country. In this study, we modified Green and Kreuter's Precede-Proceed model to analyse influence of factors in health behavior, Hierarchical regression were used in the analysis. Result: 1) Factors that had statistically significant positive relation with overall health behavior were age, educational level, income level, disease in the family, medical examination, subjective weight, and concern about health, 2) Factors that had statistically significant negative relation with overall health behavior were sex, subjective health, stress, and degree of physical activity. Conclusion: 1) It would be necessary to set the target group for the health promotion in advance. 2) It was very important to adopt easy and efficient methods to change the health behavior of target group, for example, ability to control stress.

Objectives: The purpose of this study was to evaluate effects of soda, fast food, and ramen consumption on dietary habit and health behavior of adolescents and to investigate pathway of which junk food influencing health status. Methods: The findings of this study were based on the data obtained from the 2015 11th Korea Youth Risk Behavior Web-based Survey. The analysis was accomplished using structural equation model which was designed based on the ideas that junk food consumption affects health status not only directly but also indirectly through eating habit and health behavior. Results: The structural models of both sexes revealed that the more they consumed junk food, the more negative effects it had on eating habit and health behavior. In addition, junk food consumption had an negative influence on health status directly and indirectly through eating habit and health behavior. Conclusions: The study results imply that school health education regarding proper eating habit should be implemented and that related policies should be established since complex individual, social, and environmental factors contribute to adolescents' eating habit.
