Purpose This study provided empirical support for the model that explain the formation of privacy concerns in the perspective of Information Boundary Theory. This study investigated an integrated model suggesting that privacy concerns are formed by the individual's disposition to value privacy, privacy awareness, awareness of privacy policy, and government legislation. The Information Boundary Theory suggests that the boundaries of information space dependends on the individual's personal characteristics and environmental factors of e-commerce. When receiving a request for personal information from e-commerce websites, an individual assesses the risk depending on the risk-control assessment, the perception of intrusion give rise to privacy concerns. Design/methodology/approach This study empirically tested the hypotheses with the data collected in a survey that included the items measuring the constructs in the model. The survey was aimed at university students. and a causal modeling statistical technique(PLS) is used for data analysis in this research. Findings The results of the survey indicated significant relationships among environmental factors of e-commerce websites, individual's personal privacy characteristics and privacy concerns. Both individual's awareness of institutional privacy assurance on e-commerce and the privacy characteristics affect the risk-control assessment towards information disclosure, which becomes an essential components of privacy concerns.

The purpose of this paper is to investigate a possibility of applying multimethodological approach for solving a dilemma. The motivation of this attempt is that the two different approaches, the system dynamics and the theory of constraints, resemble each other in having mental models for describing the target system and using graphic tools for representing those mental models. After a brief discussion on the comparison of the two approaches, a combined method applying to the problem of dilemma is suggested. For an experimental example, the proposed approach is applied to the sales and finance conflict on an inventory issue. The study shows that the suggested approach is able to complement each other's drawbacks. Especially constructing a stock-and-flow model and implementing a computer simulation would be very useful for quantifying the system's behavior which is hardly tracked down when applying the theory of constraints alone.

In recent decades, the socio-hydrology community has developed several socio-hydrological frameworks to understand the complexity of the coupled human-water system. Although there have been efforts to relate sociology and hydrology, there still have been some insights that remain debatable. As for this study, the Value-belief-norm theory was used to represent the human behavior in order to connect the human-water system. The theoretical framework of values, beliefs and norms was developed to understand the human culture towards the environment. In addition to the theory, norms are legislation of human behavior in the society while the values are the guiding principle to motivate beliefs and norms. The overview of this study implied on developing a socio-hydrological model consisting of the four systems defined as hydrology, socio-economy, technology and institutional. The interconnectors between the four systems are the key variables and parameters representing a module namely the causal loop diagram. Moreover, water quality, size of population, infrastructure capacity and norms are the key variables to connect the four systems. The developed model will be applied to Han River to represent the coevolutionary of the dynamics of human-water systems.

The purpose of this thesis is to study on the philosophical analysis model and its methodological application of information systems research evaluation from critical realist perspective. Fist of all, I examine ontological epistemological methodological assertions of critical realism. Because the philosophy of critical realism is an opportunity for information systems study. I examine Dobson and Mutch's critical realist perspective on actors-structure model. I suggest a critical realist actors-praxis-structure model. This model provides the potential for a new approach to social investigations in its provision of an ontology for the analytical separation of structure and agency. Of most importance might be the incorporation of non-humans into the analysis of social interaction and of technology into the elaboration of structures. I also examine Tsoukas's critical realistic meta-theory of management. I suggest a critical realist IS management model. This model elucidate the nature of management and delineate the scope of applicability of various perspectives on management. The causal powers of management reside in the real domain and, taken together, their logics are contradictory, the effects of their contradictory composition are contingent upon prevailing contingencies. I analyze Carlsson's theory of design knowledge. His framework builds on that the aim of IS design science research is to develop practical knowledge for the design and realization of different classes of IS initiatives, where IS are viewed as socio-technical systems and not just IT artefacts. The framework proposes that the output of IS design science research is practical IS design knowledge in the form of field-tested and grounded technological rules. The IS design knowledge is developed through an IS design science research cycle. In conclusion, I think that IS actors-praxis-structure model, meta-theoretical IS management model, and IS design knowledge model according to critical realistic approach are very useful for IS research evaluation. Nevertheless, important problems are left not resolved.

This study examines how marital dissatisfaction is connected with extramarital relations among married women. To explore this subject,1 am using in-depth interview techniques. The data from 16 married women who involved (and are involving) extramarital relations are collected in semistructured interviews. In this article, I describe four specific types of extramarital relations with particular relevance to marital dissatisfaction: (1) temporary extramarital relations caused by marital dissatisfaction, (2) positive extramarital relations as maintaining dissatisfied marriage, (3) unavoidable extramarital relations as breaking dissatisfied marriage, and (4) extramarital relations as a part of life with satisfied marriage. With these results, I believe that equity theory could be applicable in explaining the relationships between marital satisfaction and extramarital relations. There are limitations when the qualitative research is analyzed. One problem is measurement. It is difficult to measure equality (or equity), life dissatisfaction, and other concepts. furthermore, this study is not abbe to explain causal relationships among equality, life dissatisfaction, actual extramarital relations. The future study should perhaps be in quantitative research focused on the causal model in which all exchange variables are conceptualized and properly measured for the intimate relationship.

본 연구는 지역별로 차별적인 문화축제가 왕성하기 이루어지는 사회적 수요에 대응하여 문화 축제참가자의 만족과 재방문 관계를 규명하기 위하여 시도되었다. 본 연구는 기존의 연구설계와 차별적으로 측제참가자의 전반적인 만족도와 프로그램별 만족도를 측정하여 만족도 변수가 재방문 의사에 미치는 영향관계를 분석하였다. 연구결과, 모형 1은 각 프로그램별 만족도와 각 설명변수 중 축제 재방문 의사표명 결정인자를 도출하는 것이다. 분석결과 축제 재방문 의사결정인자로 작용하는 변수는 설명변수 중 프로그램 만족도, 방문횟수, 관람일수 등은 정의값을 보여 긍정적으로 작용하는 것으로 나타났다. 반면 소요시간은 거리마찰력의 작용으로 인하여 부의 값을 보여, 거리가 멀수록 축제 재방문 의사가 부정적으로 표출된다는 것을 보여 주었다. 모형 2는 종합적인 축제 만족도와 각 설명변수 중 축제 재방문 의사결정인자를 도출하는 모형이다. 분석결과 축제 재방문 의사결정인자로 작용하는 변수는 종합적인 축제 만족도, 출발지와 목적지간 소요시간, 방문횟수, 관람일수 등으로 나타났다. 모형 2는 모형 1과 동일하게 종합적인 축제 만족도, 방문횟수, 관람일수는 회귀계수값이 정의 값을 갖는 반면에 소요시간은 부의 값을 갖는 것으로 나타났다. 결론적으로 모형 1에 비하여 모형 2의 회귀계수값이 통계적으로 보다 유의한 것으로 보인다. 이러한 분석결과는 개별적인 프로그램 만족도를 바탕으로 만족도를 측정하는 방식과 더불어 종합적인 축제 만족도를 설명변수로 모형을 설정했을 경우, 종합적인 축제 만족도 측정이 보다 유용할 면이 있다는 것을 보여주고 있다. 그러나 축제관리가 축제의 본원적인 목적을 달성하기 위해서는 축제의 프로그램별 만족이 선행되어야만 한다는 점에 유의하여야 할 것이다.

Purpose: This study was to develop a substantive theory on the conquering experience of group-bullies among teenagers, and thereafter suggest a model for solving the problems. Method: Data collection and analysis was proceeded by a method of Grounded Theory. Data was collected by interviewing the participants. Five teenagers participated in this study who had already overcome the situation. Result: In the analysis 31 concepts, 6 categories, and 14 subcategories are extracted from the raw data, and all are constituted on the paradigm model. The causal condition is a painstaking of participants. The context is affirmative reconsidering and the phenomenon is conquering difficulties. The intervening condition is a positive intervention of a supporting system and the strategy for action/interaction is building a relationship. The consequences of this analysis is harmonizing. Conclusion: The results of this study suggest adequate ways of conquering group-bullies. These are positive attitudes towards solving problems and the full use of support systems surrounding them.

This paper presents an exploratory research on the application of the Technology Acceptance Model(TAM) to the domain of object orientation to investigate the validity of TAM in the perspective of its causal relationships. In the Management Information Systems(MIS) area, TAM has been applied to computer usage behavior as a specific technology adoption model. This paper also suggests the factors that affect the technology acceptance of object orientation in U.S. organizations through a modified TAM. Two major research questions are addressed. First, this research investigates the effect of these external variables on the dependent variable, the actual usage of object orientation in the viewpoint of knowledge interaction between structured methods and object orientation. Second, is TAM valid for the technology acceptance of object orientation in terms of its causal relationships? This study empirically explores the impact of the external variables on the level of actual usage of object orientation via the mediating variables in TAM. A structured questionnaire is administered to Data Processing Management Association(DPMA) professionals in US. The result of this study reveals one important contradictory finding that is not consistent with expectations based on related theory. TAM does not accommodate the technology acceptance of object orientation perhaps because object orientation is a complex and organization-level adoptive technology or the measures for the mediating constructs in TAM may not be appropriate in industry settings.

The present study examined the causal relationships among nurses' job environment /job characteristics(work overload, lack of autonomy, professional role conflict, interpersonal relationships), maturity, job stress, job satisfaction and turnover intention by constructing and testing a theoretial framework. Based on Katz and Kahn's (1978) theory of organizational open system and Kahn, Wolfe, Quinn, and Snoek's (1964) theory of stress, nurses' turnover intention, job satisfaction and job stress were conceived of as outcomes of the interplay between personal characteristics and work environment. Personal aspects associated with outcome variables included professional knowlege and skill, and maturity(challenge, commitment, control, responsibility). The work environment factors involved work overload, lack of autonomy, professional role conflict, and interpersonal relationships (social support). Three university hospitals located in Seoul were selected to participate. The total sample of 443 registered nurses represents a response rate of 96 percent. Linear structural relationships (LISREL) technique was used to test the fit of the proposed conceptual model to the data and to examine the causal relationships among variables. The result showed that both the proposed model and the modified model fit the data excellently, revealing considerable explanatinal power for job stress and job satisfaction. The explanatory power of turnover intention was relatively lower than those of stress and satisfaction. In predicting nurses' stress, satisfaction and turnover intention, the findings of this study clearly demonstrated that professional role conflict might be the most important variable of the all the environmental variables and personal characteristics. The results were dis-cussed, including directions for the future research and practical implications drawn from the research were suggested.
