Recently, As the IT skills development, the different kinds of data (or information) generated by the company are becoming more frequent leaked to outside organizations and individuals. However, it is insufficient situation to reduce the dysfunctional corporate information at the enterprise level. In this paper, we propose a role-based enterprise information processing model to minimize the dysfunctions of corporate information. The proposed model is to allow you to set protect corporate information through the relevant departments for the management and supervision of enterprise information, and rapid and systematic recovery and operating strategy was to improve the efficiency of enterprise information services. The proposed model is caught blocking access to information access to information to establish a rapid and systematic recovery and operational continuity strategy after the administrator user permissions and roles that access to information is centrally managed by the user when the abnormality. In experimental results, virus damage was lower 48.8% than the previous model. In addition, information on the number of dysfunction distribution occurring within the company gained 17.9% lower results than the previous model.

유전 위험 사정과 상담서비스가 임상실무에 널리 적용되어 감에 따라, 다양한 비용효율 면에서 다양한 상담서비스 모델을 사정하고, 대상자의 임상 요구와 건강문제를 해결하는데 어떤 모델이 유용한 지 확인할 필요가 있다. 본 연구의 목적은 114건의 현장 관찰과 문헌고찰을 통하여 3가지 유전상담 모형을 분석하였다. 유전의학 전문가 모델, 유전상담사 모델, 임상연구전문가 모델을 중심으로 각 모델의 구조, 전문가의 역할 및 기능, 목표, 물리적 세팅, 교육도구 등을 분석하였다. 각 모형 안에서 환자에게 기대되는 결과 면에서 질적 서비스가 보장되는지 확인하기 위하여 이론적 분석을 실시하였다. 본 연구를 통하여 각 모형의 상담 전, 중, 후 환자 만족, 지식 변화, 상담 효과 및 커뮤니케이션 효과 등을 분석하였지만, 결론적으로 상담서비스가 이루어지고 있는 기관의 구조를 충분히 고려하지 않은 상태에서 최상의 서비스 모델을 제시하기 어려울 것임을 논의하였다.

인터넷이 발전하고 성장함에 따라 전자상거래(Electronic Commerce)는 초기의 단선적인 관계와 집중화된 구조를 탈피하여, 상호 연관적인 관계 및 분산되고 개방적인 구조를 바탕으로 수행되고 있다. 즉, 인터넷의 본질적인 특성인 네트워크를 기반으로 하는 시장구조가 형성되고 있으며, 이러한 네트워크 시장구조를 기반으로 하여, 새로운 형태의 비즈니스 모델이 출현하고 있다. 네트워크 효과(Network Effect)를 기반으로 하는 네트워킹 비즈니스 모델은 초기의 비즈니스 모델과는 다른 형태의 정보흐름(Information Process) 및 구조(Architecture)를 가지며, 이로 인해 전자시장(Electronic Market)에서 참여자의 역할 및 사업 전략, 수익모델 등이 변화되고 있다. 이 논문에서는 네트워킹 비즈니스 모델이 가지는 구조 및 특성을 규명하고, 사례분석을 통해 다양한 형태의 네트워킹 비즈니스 모델을 분류하여, 네트워킹 비즈니스 모델의 활용가능성을 모색해보고자 한다.

Policy-Based Network Management (PBNM) architecture is to meet various needs of network users and to provide effective management facilities in distributed and large scale networks to network managers. In PBNM, network managers perform network management operations by stipulating a set of rules rather than control each network component. On the other hand, providing security services such as authentication, privacy of messages as well as a new flexible and extensible administration framework, SNMPv3 enables network managers to monitor and control the operation of network components more secure way than ever before. Despite of its enhanced security services, SNMPv3 has difficulties in managing distributed, large-scaled network because it does not provide centralized security management facilities. In this paper, we propose a new security model called Role-based Security Management model (RSM) with security management policy to support scalable and centralized security management for SNMP-based networks. Also, the structure and the operation of the security system as well as the efficiency analysis of RSM in terms of security management are also described.

Role-based Access Control (RBAC) model appears to be the most appropriate technique for access control to minimize the errors likely to occur in managing users and network resources. In this paper, we introduced the Work-concept RBAC model that is the result of the Work concept imported to the role based access control model. Using our extended access control model a user could select a work which is more abstract and more inclusive concept than role to do his work. Additionally even if the user has an authority through selecting a work, if a user has no relation to his assigned job, it will be automatically prohibited.

Problem-Based Learning(PBL) is one of constructionism's model which is learner-centered learning. In this paper, a role-play base PBL using character is proposed to study importance of information security. It is different from the other PBL models in that it reflects the characteristics of learners, learning task. And it is learning support system which the learners preside their own learning activities using Internet and mobile devices. By experimental result showed that proposed method was more effective than traditional teacher-oriented teaching method about information security in self-directed learning, cooperative learning, contents-making and attraction.

The purpose of the study was to examine the role of cognitive costs in the relationship between service quality and store loyalty using structural equation modeling. The findings showed that cognitive costs playa mediating role between service quality and store loyalty. The findings also showed that physical environment indirectly affected store loyalty through cognitive cost. However, personal service had both direct effect and indirect effect on store loyalty. It was also appeared that there were differences in the models between customers and prospects.

분산 가상 환경은 고속 통신망과 컴퓨팅 환경의 고급화로 응용 분야를 넓혀 가고 있으며, 보다 현실감 있는 상호작용으로 인해 만남과 대화, 협력 작업, 상거래, 오락 등의 인간의 사회적 활동을 지원하는 새로운 수단으로 자리잡고 있다. 가상 도시와 같은 대규모의 가상 환경에는 공원이나 거리, 건물의 로비 등과 같은 개방적인 공간과 사무실과 같은 업무 공간, 그리고 쇼핑몰과 같은 상거래 공간들이 공존하게 되므로 접근 제어와 보안이 보다 중요한 문제로 대두된다. 따라서, 이 논문에서는 분산 가상 환경내의 모든 사물들을 객체로 인식하고, 객체에 대한 역할을 기반으로 하는 접근 제어 모델을 제안하고, 제안한 모델을 기반으로 접근 제어 관리자를 설계하였다. 설계된 접근 제어 관리자는 가상 환경내 공간의 객체 뿐만 아니라 공간 자체도 하나의 객체로 인식하여 접근 제어를 하였다. 또한, 대규모 공간에서의 중요한 특징인 관리의 용이성과 동적인 변경을 가능하게 하기 위해, 역할을 기반으로 참여자와 객체를 연결하고, 객체가 갖고 있는 행위까지를 제어할 수 있었다.

This research aims is to confirm the influence of a teacher's teaching style and teaching career on instructional analysis. Through this, the differences in the relevant elements' view points on a class and those in teachers' analysis view points on class criticism and instructional analysis at the education field can be investigated. For this study, the teaching styles of 198 elementary school teachers were categorized, their teaching careers were checked as teaching career and set them as covariate, and the differences in the view points on the analysis of the class climates were verified depending on each teaching style. As the research result, meaningful differences were found in four areas of the elements of class climates analysis, that is, creativity, vitality, precision, and gentleness. In the analysis of the class climates, the teachers with a professional style among the teaching styles gave the highest grades to creativity in the same class, those with a facilitating style to vitality, those with a role model style to precision, and those with a facilitating and role model style to gentleness. On the other hand, those with an authoritative and a delegating style were proved to give the lowest grades in general class climates. It means that teachers with different teaching styles have different viewpoints when analyzing a class, and those with a professional, a role model and a facilitating style have a relatively stronger intention to analyze a class through reflective introspection and permissive recognition.

This research paper aims to provide valuable data to the policy makers in establishing business activation plan through improving university students'entrepreneurial intention by carrying out international comparison research regarding the social environmental factors that influences entrepreneurial intention. There have been multiple researches on personal traits that affect entrepreneurial intention in the past, but this paper examines the social environmental factors that impact entrepreneurial intention. The result of this study is as follows. First, university's assistive activity for entrepreneurship, successful entrepreneurial role model, and business market scale has positive effect on entrepreneurial intention, while government assistive policies for entrepreneurship has no direct effect on entrepreneurial intention. Second, there were some differences of entrepreneurial intention in demographic characteristics. The mean of entrepreneurial intention was highest in Chinese students. Students who have ever started their own business were highest in total mean comparison of entrepreneurial intention. Also entrepreneurial intention mean was higher in men generally. Beside, discussion is made on the implication of the study, the limitations of the study, and some directions for future studies.
