유비쿼터스 환경의 핵심 기술인 USN은 배터리 용량 및 연산능력이 제한된 자원하에서 운영되어야 하며 이로 인하여 USN은 저 전력소비 및 최소의 연산량을 유지하기 위한 경량화된 설계가 반드시 요구된다. 이전의 J$\emptyset$sang의 신용모델에 기반한 USN상호인증 방법은 최소의 연산 기능만을 적용하여 경량화 된 상호인증이 가능하다는 특징이 있으나, 신용을 표현하기 위한 구성요소들의 속성이 경량성의 측면에서 미비점을 갖는다. 본 논문에서는 USN에서의 경량 상호인증에 적용하기 위해 J$\emptyset$sang 모델을 개선한 신용모델을 제안한다. 제안된 USN신용모델은 오직 신용 표현 대상(x)의 믿음(belief)의 정도만을 적용하여 신용정보를 정의한다 정의된 신용정보는 확률 및 논리 연산(AND)에 기초하여 정보를 계산하기 때문에 기존 J$\emptyset$sang의 신용모델 보다 계산량 측면에서 경량성을 가진다.

Intensified competition, splintered mass market, shortened product life cycles, and advanced technology and automation let companies to crease the IT investment to meet the changes, Although IT investment increased, IS didn't show the visible outcome. One of the major interest of IS managers is how to demonstrate the business value of the firm's investment in information technology. This paper proposes the revised model of Nelson & Cooprider(1990) regarding shared knowledge between IS and line groups. Knowledge can be shared through mutual trust, mutual influence and communication between these two groups. The revised model including communication is tested empirically using LISREL. The results show that shared knowledge mediated the relationship between IS performance and mutual trust, mutual influence and communication. And shared knowledge between IS and line groups increase IS performance. IS managers should develop mutual trust, mutual influence and communication between these groups to achieve more shared knowledge and higher IS performance.

This article proposed the authentication protocol for peer-to-peer resource sharing community. The proposed protocol does not require a priori information for generating and exchanging authentication key. Also this protocol can provide the delicate access control by allowing the user(authenticator) to assign the trust level to the authentication supplicant, which can be used to decide if the resource providing node will accept the resource sharing request from a resource requesting node. Trust Relationship Chaining provides the environment where trust levels (included in the trust table) of nodes in the resource sharing community are propagated among nodes when trust tables are exchanged between two nodes engaged in mutual authentication process and authentication refresh so that any two nodes which are not directly mutual-authenticated can assign the trust level each other for the access control for resource sharing. In the proposed protocol a node can implements the authentication refresh continuously to verify the effectiveness of authentication after mutual authentication so that the authentication of new node or authentication revocation(effectiveness cancellation) of the departed node can be propagated to the all the nodes in RSC and eventually safe resource sharing community is configured.

There are many studies which reveal most of the accidents are related to pilot errors. Looking at each phase of flight, the accidents which occurred at the segments of take-off and landing consist of 70%, cause these phases need precise cooperations between pilots and ATC specialists to make sure every instructions understood and instruments to be normal. Therefore, the accidents of these phases leave great regrets and the price was enormous to people and equipments. Until now, most of the studies investigate the accident itself and very few show the relationships between pilots and air traffic controllers. This study analyzes the impacts of inter-dependence to mutual trust, cooperations and relationship efficiency between them who play important parts in flight. Based upon the findings, the inter-dependence has an effect on mutual trust and the latter influences to cooperations. Also, mutual trust and cooperations have a leading role in the relationship efficiency. It implies that mutual trust, cooperations, and the degree of inter-dependence are important factors to improve the relationships between them.

Recently, an effective building and utilization of information system are essential in franchise firms as well as corporate management. Accordingly, this study is to examine the structural relationships among partnership quality of supplier, trust with a supplier and commitment, and franchise information system performance based on Henderson's(1990) information system partnership model and Lee and Kim's(1999) partnership model. For these purposes, the authors developed several hypotheses. The data were collected from 173 franchisors and analyzed with SPSS 18.0 and AMOS 18.0 The results are as following. First, sharing knowledge, interdependence, and mutual benefit influence supplier trust, but do not influence commitment. Second, supplier trust affect commitment and it prove that supplier trust is a full mediating role between partnership quality and commitment of franchise and information system supplier. Third, both supplier trust and commitment have a positive effect on performance of franchise information system. Therefore, it implies that supplier trust is significant factor in an performance of franchise information system. At the end of this paper, managerial and theoretical implications, limitations and future research directions were suggested.

The present research aims to identify the relationship between trust and distrust in an online business environment. To clarify the concepts, cognitive-affective personality system theory was introduced, through which five types of psychological units were proposed. In developing the research model based on the theory, technical effectiveness of the system and content truthfulness of the website were selected as two key stimuli for the coding process of online users. Trust and distrust were selected as mediating factors that generate consequent behaviors. Finally, purchase intention served as a final dependent variable. Assuming that trust and distrust emerge in psychologically different stages, this study hypothesized the mutual causal relationship between trust and distrust, indicating that the relationship will be determined by their contextual emphasis on each dimension. To validate, a survey was conducted with 307 online shopping mall users. Results show that stimuli were more significantly associated with trust. Trust is therefore a more cognitive construct than distrust, and the path from trust to distrust is stronger than that from distrust to trust. This finding implies that the cognitive aspect of trust is stronger than that of distrust. Distrust is rather more affectively emerging than trust.

본 연구는 중소기업의 관계구조가 구매자-판매자 관계를 기반으로 하는 아웃소싱에 있음에 주목하고, 중소기업의 활동에서 신뢰경영과 동반성장이 가진 역할을 검정하는데 목적이 있다. 신뢰경영과 동반성장이 기업의 여유자원, 협력관계 그리고 구매자-공급자 관계를 매개로 아웃소싱의 유형을 결정하면 그 성과를 얻는다는 맥락을 가지고 있다. 이러한 맥락에 따라서 연구가설을 설정하고 연구모형을 구축한 다음, 구조방정식모형으로 실증분석을 하였다. 실증분석을 위해 전국의 206개 중소기업을 대상으로 설문조사에 얻은 자료를 이용하여 가설을 검정하였다. 그 결과, 신뢰경영과 동반성장이 아웃소싱 유형과 성과에 유의한 영향을 미치고 있으며, 그 과정에서 협력관계와 구매자-공급자관계의 매개효과가 있었다.

Cloud computing is an emerging business model popularized during the last few years by the IT industry. Providing "Everything as a Service" has shifted many organizations to choose cloud-based services. However, some companies still fear shifting their data to the cloud due to issues related to the security and privacy. The paper suggests a novel Trust based Mutual Authentication Mechanism using Secret P-box based Mutual Authentication Mechanism (TbMAM-SPb) on the criticality of information. It uses a particular passcodes from one of the secret P-box to act as challenge to one party. The response is another passcode from other P-box. The mechanism is designed in a way that the response given by a party to a challenge is itself a new challenge for the other party. Access to data is provided after ensuring certain number of correct challenge-responses. The complexity can be dynamically updated on basis of criticality of the information and trust factor between the two parties. The communication is encrypted and time-stamped to avoid interceptions and reuse. Overall, it is good authentication mechanism without the use of expensive devices and participation of a trusted third party.

이 논문은 중학생의 개인특성에 따른 부모애착 관계와 부모애착이 진로성숙도에 미치는 영향을 알아보고자 하는 것이다. 연구대상은 충남 아산에 위치한 00중학교 1-3학년 학생이다. 개인특성은 성, 학년, 성적, 부모의 학력, 경제수준이며, 부모애착은 상호신뢰, 소외, 의사소통 이다. 진로성숙도는 결정성, 목적성, 준비성, 독립성, 확신성으로 분류하였다. 연구결과 개인특성에 따른 부모애착의 관계에서는 성, 성적, 부모학력, 경제수준의 요인에서 모두 유의미한 차이를 보였다. 부모 중에 모의 애착에서 남학생보다는 여학생이 더 높게 나타나 성별의 차이를 보였으며, 성적은 부모 모두에서 부모의 성적이 높을수록 애착이 높게 나타났고, 경제수준은 부모 중에 부에서만 경제수준이 높을수록 애착이 높게 나타났다. 그리고 부모애착이 진로성숙도에 미치는 영향에서, 소외는 부모 중에 부에게서만 부(-)적인 영향을 미치는 것으로 나타났으며, 상호신뢰와 의사소통은 모두 부모 중에 모에서만 정(+)적으로 진로성숙도에 영향을 미치는 것으로 나타났다. 또한 진로성숙도의 하위변인 중 확신성을 뺀 결정성, 목적성, 준비성, 독립성에서 유의미한 결과를 보였다. 결정성은 모의 의사소통이 목적성은 모의 상호신뢰가 유의미한 영향을 주었고 준비성은 부의 상호신뢰와 모의 의사소통에서 독립성은 부의 부(-)적 소외와 모의 정(+)적 상호신뢰가 진로성숙도에 영향을 미치는 것으로 나타났다. 이러한 결과는 청소년시기 중에 사춘기를 겪는 중학생들의 부모와의 관계 진로성숙에 대한 행동심리를 이해할 수 있는 참고자료가 될 수 있다고 사료된다. 단 특정 지역과 소수의 중학생을 표본으로 진행한 연구라는 한계점이 있다.
