It is very important to understand system behaviors in collective pattern for each knowledge domain. However, there are structural limitations to represent collective behaviors because of the size of system components and the complexity of their interactions, causing the state explosion problem. Further composition with other systems is mostly impractical because of exponential growth of their size and complexity. This paper presents a practical method to model the collective behaviors, based on a new concept of domain engineering: behavior ontology. Firstly, the ontology defines each collective behavior of a system from active ontology. Secondly, the behaviors are formed in a quantifiably abstract lattice, called common regular expression. Thirdly, a lattice can be composed with other lattices based on quantifiably common elements. The method can be one of the most innovative approaches in representing system behaviors in collective pattern, as well as in minimization of system states to reduce system complexity. For implementation, a prototype tool, called PRISM, has been developed on ADOxx Meta-Modelling Platform.

It was argued that the collectivism found among Koreans are quite differenct from the collectivism defined by Western theories. The study aims to define the dimensions of the Korean collectivism (Uri, we-ness) and to examine the influence of Uri dimensions on various interpersonal communication behaviors. Result found that Uri was composed of six dimensions: Mental support, group-selfishness, group-skepticism, individual sacrifice, group-oriented attitude, and emotional intimacy. The six dimensions were able to be integrated into positive collectivism (mental support, group-oriented attitude, emotional intimacy) and negative collectivism (group-selfishness, group-skepticism, individual sacrifice). It was found that positive collectivism generally influenced on constructive communication behaviors while negative collectivism generally influenced on deconstructive communication behaviors.

This study explores high school gifted students' perception of cheating in school using the concept mapping method. The map shows the gifted students' concept structure and the different perception between gifted and non-gifted students on cheating. For the purpose, 63 high school gifted students participated at the brainstorming stage to gather the possible related statements. Finally, 64 statements were confirmed and these were divided and evaluated by 13 focus group students. Then, they were analyzed by multidimensional scaling and processed by hierarchical cluster analysis. The results compiled from this procedure show that high school gifted students' perception of cheating is classified into five clusters: "unacceptable cheating behaviors of friends", "an inseparable relation among social structure, giftedness and cheating", "conflict, coping skills, and tolerance related to the cheating", "immorality in one's inner person" and "the judgement based on morality and social justice". In addition, 150 gifted students and 160 non-gifted students checked the degree of agreement to each statement with the likert 6 points scale and the result showed that there was no significant difference in two clusters, "unacceptable cheating behaviors of friends" and "the judgement based on morality and justice", while it turned out that there were significant perception gaps in three clusters, "inseparable relation among social structure, giftedness and cheating", "conflict, coping skills, and tolerance related to the cheating" and "immorality in one's inner person". Implications of the study related to the gifted students' moral behaviors were discussed in depth.

This study suggests internal and external virtuous behavior in organization influenced employees' organizational citizenship behavior (OCB), organizational loyalty and emotional exhaustion through mediated effect of affective commitment and collective self-esteem. Virtue in organization has received attention as critical attribute of positive organizational scholarship. Cameron(2003) defined the study of virtue as a study of the capacity, attributes, and reserve in organization that facilitates the expression of positive deviance among organization member. Accordingly, this study presumed that virtuous behaviors within organization positively associate with OCB, and organizational loyalty through affective commitment whereas the virtuous behaviors negatively influence emotional exhaustion. On the other hand, we assumed that external virtuous behaviors positively associate with OCB and organizational loyalty and negatively associate with emotional exhaustion individually. In study 1, we conducted interview with Korean employees created items for internal and external virtue, and implemented empirical study for 253 employees of domestic companies in study 2. This study contributes to the empirical investigation on how internal virtue (i.e. the employees' virtue for their organization) and external virtue (i.e. the organization's virtue for society), used as independent variables, influence employees' organizational citizenship behavior (OCB), organizational loyalty and emotional exhaustion after creating items for the two virtuous behaviors through qualitative research.

The purpose of this study was to test the structural model for the effect on abnormal eating behavior targeting 493 nurses. Results, The direct effects of variables affecting abnormal eating behavior were in the order of eating abstinence and socially imposed perfectionism, and these variables explained 85% of abnormal eating behavior. Explicit narcissism had a significant effect on abnormal eating behavior through socially imposed perfectionism and eating restraint, and sociocultural attitude toward appearance through eating restraint. In the multi-group moderating effect, the path coefficients between job stress and abnormal eating behavior, socially imposed perfectionism and abnormal eating behavior were different between groups. Therefore, it is necessary to find a way to lower the socially-imposed perfectionism and nursing intervention that can escape excessive eating abstinence.

This study investigates whether earnings management behavior of chaebol firms differ from that of non-chaebol firms. The ownership structure of chaebol firms is characterized by the dominance of one largest shareholder and his family members who typically participate in the management of the firm directly or indirectly and influence most of the important management decision. This study adopts the random effect model and the hausman and talyor model, using a panel of 5092 firm-year over a period from 1991 to 2010 to control for potential heterogeneity and endogeneity that may cause sever bias. This study finds that there is no difference in accrual based earnings management level between chaebol firms and non-chaebol firms. However, chaebol firms appeared to engage less real earnings management that is known to negatively affect future earnings and share prices. The results are consistent when controlling for potential heterogeneity and endogeneity in the hausman and taylor model. The results may be of interest to various stakeholders, policy makers, standard setters and academic researchers.

Globally, awareness about obesity is increasing rapidly. In Korea, obesity is recognized as a disease and steps are being taken to treat it. From the health governance point of view, such standardized measures amplify the risk of obesity and thus play an important part in the prevention of the disease. In this context, various obesity treatments act as a medium for the problem-solving process. In recent years, obesity surgery has been viewed as a rational solution to the problem of obesity. In the context of standardization of treatment, Callon's "Process of Translation" in STS theories highlights the importance of the central actor (Obligatory Passage Point; OPP). However, in the case of obesity, it is difficult to identify a single OPP to project different perspectives of an actor's needs. "Lapband surgery" often acts as a "boundary object" in this context. This article assesses this absence of central actors in the process of problem solving through a case study of adoption of Lapband surgery in Korea. Further, we attempt to suggest an analytical framework with a boundary object and multiple translation concepts to aid solving the problem of obesity.

The purpose of this study was to explore 1) the illness experiences, 2) health behaviors (causal thoughts), and 3) health beliefs (health behavior changes after cancer diagnosis) among Korean breast cancer survivors using focus groups, which is a form of qualitative research methods. Thus, this study intended to understand how the illness experiences and health beliefs are associated with health behaviors. Three focus groups composed of 16 breast cancer survivors living in Seoul and GyeongGi were conducted with 5 to 6 people in each group. For illness experiences, health beliefs, and health behaviors of breast cancer survivors, some major themes related to physical, behavioral, psychological, and social domains were identified. Understanding health beliefs and health behaviors for Korean breast cancer survivors will be an important step toward developing social work interventions for enhancing health promotion.

정보시스템 분야에서 성공적인 정보시스템 개발을 위하여 사용자 참여, 몰입, 만족 과 관련된 많은 연구가 진행되었다. 초기의 연구에서는 사용자 참여와 몰입의 개념이 혼용 되었으나 현재는 구분되는 개념으로 사용되고 있다. 초기 연구에서 몰입과 만족에 관한 연 구가 있었으나 구분되는 개념으로 보았을 때 몰입보다는 참여와 만족에 관한 연구로 보아야 할 것이고, 그후 진행된 대부분의 연구가 사용자 참여와 만족간의 관계에 대한 것이었다. 이들 연구에서는 사용자의 참여 정도가 사용자 만족에 어떠한 영향을 미치는가를 분석하였 다. 그러나 이들의 연구는 일관성 있는 결과를 제시하지 못하였는데, 이와 같은 결과가 나 타난 데에는 다른 여인도 작용하였겠지만, 개발에 참여한 사용자의 주관적 심리 상태인 사 용자 몰입 정도의 차이가 결과의 불일치를 가져오는 요인으로 작용하였을 수 있다. 본 연구 에서는 사용자 참여와 몰입간의 관계를 분석하기 위하여, 시스템 개발에서 사용자와 개발자 간의 관계를 집단으로 간주하여, 집단의 구조적 측면과 집단의 행위적 측면에서 이들 관계 를 분석하였다. 이들 관계에 영향을 주는 조절변수로 구조적 측면에서는 공식화, 집권화 정 도를, 행위적 측면에서는 갈등의 정도, 집단 응집성, 의사소통 수준을 사용하였다.
