본 논문에서는 워크플로우 모델링 도구인 ICN(Information Control Net) 모델을 이용하여 워크플로우 역할 의존성 분석 메커니즘을 제안하였다. 즉, ICN 모델로 정의된 워크플로우의 각 액티비티(activity)들 간에 존재하는 역할 의존 관계를 표현하기 위하여 역할 의존 넷(Role Dependency Net)을 정의하였고, ICN 모델로부터 역할 의존 넷을 생성하는 알고리즘을 제안하였다. 본 논문에서 제시된 알고리즘을 이용하여 생성된 역할 기반의 워크플로우 모델은 any-cast 워크플로우와, multi-cast 워크플로우 작업환경을 제공함으로써 현재 대부분 조직에서의 작업 환경인 객체지향 작업 환경 및 분산 작업 환경에서 워크플로우 관리 시스템을 구축할 수 있다.

본 연구는 어머니의 스마트폰 과의존과 부모역할지능의 관계를 확인하여 어머니의 스마트폰 과의존 예방교육이 필요하다는 기초자료를 제공하는데 목적을 두고 있다. 연구대상은 충북 청주시의 15개소의 어린이집에 다니고 있는 만 0~2세 어머니 220명이다. 연구도구는 스마트폰 과의존척도, 부모역할 지능척도를 사용하였다. 연구의 분석을 위하여 Pearson 적률상관관계, 회귀분석을 실시하였다. 분석결과 어머니의 스마트폰 과의존은 부모역할지능과 부적인 상관이 있었으며 발달적 자극, 양육 및 지지, 관리의 하위요인 모두에 부적상관이 있었다. 다중회귀분석을 통한 스마트폰 과의존과 부모역할지능 및 하위요인 모두에 부적으로 유의한 영향이 있는 것으로 나타났다. 이는 바람직한 영유아의 양육을 위하여 어머니를 위한 스마트폰 과의존 예방교육이 필요함을 시사한다.

In this paper, this model ensures confidentiality and integrity of mandatory access cotrol policy which based on fuzzy function with importance of information. And it solves authorization abuse problem through role graph creation algorithm and flowing policy that security grade is applied. Because this model composes role hierarchy which bind similar role concept to apply to commercial environment, it has expansile advantage by large scale security system as well as is easy that add new role.

The purpose of this study is to investigate the impact of Argument-Based Inquiry (ABI) strategy on student's character competency. For this study, 51 grade 11 students (two classes) were selected to the role assignment (ABI-R group) and 46 students (two classes) were assigned to the non-role assignment group (ABI group). In the result, the role assignment group (ABI-R group) showed a statistically higher change in character competency than the group without role assignment (ABI group). Particularly, the ABI-R group has significantly higher grade than ABI group in empathy, responsibility, and respect among the sub-factors of character competency. However, in the case of the cooperation factor of character competency, the ABI group showed statistically significant higher grade than ABI-R group. The results of this study showed that Argument-Based Inquiry (ABI) as teaching and learning strategies in science can contribute to the enhancement of human character competency. In addition, we suggest that students should be actively involved in the class through role assignment, but it is necessary to present the class situation so that they can be actively engaged according to the problem situation rather than being fixed in a given role.

This study examined the relationship between emotional labor, job stress and job performance for 226 social workers. The main results are as follows. First, the degree of attention to emotion expression, a sub-concept of emotional labor, had a positive effect on role conflict, a sub-concept of job stress, and emotional disharmony had a positive effect on role overload and role conflict. Second, attention level, emotional disharmony, and frequency of emotional labor, which are sub-concepts of emotional labor, did not have a statistically significant effect on both job performance and sub-concepts, role conflict, role conflict, and job ambiguity. Third, role overload and role conflict, which are sub-concepts of job stress, have a statistically significant negative impact on both in-role performance and out of role performance.

This study investigates the relationships between parental efficacy and parental practices among Korean immigrant parents in the US. Parental efficacy constitutes a special aspect of parental belief systems focusing on the beliefs that parents have the capabilities to manage the tasks of nurturing and socializing their children. Results showed that parental efficacy was positively related to the authoritative dimension of parental practices. However, there was no significant negative relationship between parental efficacy and the authoritarian dimension of parental practices. Interestingly, the authoritative and authoritarian dimensions of parental practices were highly correlated among Korean immigrant parents. This finding is in contrast to much of the research on Anglo American parenting that indicates that authoritarian practices are not compatible with authoritative practices. For Korean immigrant parents, authoritarian practices seem not to have detrimental connotation. Therefore, it can be assumed that Korean immigrant parents parental practices have different underlying mechanisms compared to Anglo American parents. We need to focus parenting research with a broader perspective on the sociological and historical context from which parental practices arise.

The Knowledge Creation in early stages of new service development plays a critical role in the success of the service. The user is a crucial resource in creating knowledge in early stages of development, and user involvement is necessary. There are three roles the user can take part as in service development: informative, consultative, or participative. Based on these different roles, the process of knowledge creation varies. With this background, we proposed to investigate which creative processes need to be passed through in order to positively affect service development based on the role of the user in early stages of Internet service development. This case study was undertaken based on two new projects. The results of this study reveal the relationship between the knowledge creation process and user in early stages of development and at the same time provide guidelines regarding user involvement in actual service development.

This study look into a role change and geographical inertia of the central place. The place is selected and progressed as the center which is the joining of physical condition and social situation of the region. The central place is the role change according to social change but it has geographical inertia as the central place. The result is as follows. Firstly, the role of regional center is changed. This sample region is the center of a national defense and administration and traffic in Three-Country period. But the role of the national defense is disappeared with the unity of the three countries. A traffic center facility was lost because of traffic axis changed from the east-west line to the north-south line when Ko-Ryo period. A facility loss as a traffic center leads to diminish the administration function and the movement of the regional center within that area. Secondary. the new regional center function was maintained by the joining of an outside and inside peoples. It maintained the geographical inertia by Confucianism culture instead of administration function. Thirdly, it had geographical location movement within the area.

The network analysis is done to explore what kind if issues are diffused about earthquake and the role of social media. The types of disaster information is classified into formal and informal. The role of actor is classified based on the concentrativeness and the diffusion of issue. Youttube is functioned as a formal channel and an informal channel when disaster happened. In case of government's video, issue contractiveness is high but the diffusion is low. In case of media's video, issue contractiveness and the diffusion are all high. In case of individual channel, issue contractiveness is low, but diffusion is high. In disaster, youtube is a tool to respread the disaster issue. Government needs to try diffusion of government's news actively in disaster.
