본 논문에서는 NoC 기반 SoC의 테스트 시간을 감소시키기 위하여 NoC를 TAM으로 재활용하는 구조를 바탕으로 하는 새로운 형태의 스케줄링 알고리즘을 제안한다. 제안한 방식에서는 기존 연구된 NoC 테스트 플랫폼을 사용하여 스케줄링 문제를 rectangle packing 문제로 변환하고 이를 simulated annealing(SA) 기법을 적용하여 향상된 스케줄링 결과를 유도한다. ITC'02 벤치회로를 이용한 실험 결과 제안한 방법이 기존 방법에 비해 최대 2.8%까지 테스트 시간을 줄일 수 있음을 확인하였다.

FCM(Fuzzy Cognitive Map) is proposed for representing causal reasoning. Its structure allows systematic causal reasoning through a forward inference. Authors have already proposed a diagnostic system based on FCM to utilized to identify the true origin of fault by on-line pattern diagnosis. In FCM based fault diagnosis, Temporal Associative Memories (TAM) recall of FCM is utilized to identify the true origin of fault by on-line pattern match where predicted pattern sequences obtained from TAM recall of fault FCM models are compared with actually observed ones. In engineering processes, the propagation delays are induced by the dynamics of processes and may vary with variables involved. However, disregarding such propagation delays in FCM-based fault diagnosis may lead to erroneous diagnostic results. To solve the problem, a concept of FTCM(Fuzzy Time Cognitive Map) is introduced into FCM-based fault diagnosis in this work. Expecially, translation method of FTCM makes it possible to diagnose the fault for some discrete time. Simulation studies through two-tank system is carried out to verify the effectiveness of the proposed diagnostic scheme.

Recently MVNO has been adopted to reform the monopoly structure of mobile telecommunication industry in Korea. MVNO is expected to not only enable mobile telecommunication industry more free, but also provide various welfare service with customers, in particular mobile payment system service. Based on TAM, this paper is to investigate the affecting factors of intention to use of mobile payment system service in MVNO environment. The results indicate that all system quality factors are significantly related to both perceived usefulness and perceived easy of use, but only stability of service quality factor is significantly related to the perceived usefulness. Perceived easy of use was found to be siginificantly related to the intention to use of mobile payment system in MVNO environment, but percevied usefulness was not.

The purpose of this study is to shed light on the driving motivations of contributing social word of mouth on social networking sites (sWOM) toward both tangible and intangible products. In order to develop a research model, this study adopts the motivation theory and TAM model. Data was collected from 904 members of the cosmetic and restaurant communities by using the snowball method. After assessing the validity of all constructs, the structural equation modeling (SEM) is used to test the proposed hypotheses. Results show that personal motivations (satisfaction, opinion leadership, self-enhancement, and economic incentives) and characteristics of sWOM (Perceived Usefulness and Ease of Use) have positive effect on exposure and engagement behaviors. Here are our specific findings, (1) customer satisfaction positively affects online interactions on SNSs such as Like or Sharing a content; (2) sWOM contribution behavior exists in two structures (Exposure and Engagement) and affects each other; (3) This study combines two groups of personal motivation and TAM to conceptualize a research model; and (4) The motivations of contributing sWOM between a specified service and product are rather similar. These findings help digital managers to understand consumers' behavioral contributions on SNSs and also provide interesting insights for marketers.

Korean government is planning to adopt double entry bookkeeping with accrual basis in the government accounting system. This paper attempts to identify influencing attitudes of information producers toward the acceptance of the new service system. Several models are introduced, including Luder's Contingency Model, Cheng's Politico-Economic Model of Accounting Policy Choice, Roger's Diffusion of innovation, and Davis's Technology Acceptance Model(TAM). A set of constructs are developed as fellows : information producers' knowledges, experiences, altitudes toward the reform, characteristics of cash based accounting system and new accrual based system, a chief executive officer's willingness to support, availability of supporting systems, and social Influences from external environment. This study also incudes hey factors used in TAM, such as perceived usefulness and ease of use. Survey responses are gathered from accounting officers in government ministries and agencies as well as from local governments. Regression analysis shows that, for information producers, both 'perceived ease of use' and 'perceived usefulness' of the new system are the best explanatory variable for the dependent variable. It has also found that 'perceived usefulness' is explained best by individual characteristics such as knowledge and experiences, quality of current cash based s1n91e entry bookkeeping system, chief executive's support, Positive supporting systems and social influences. The useful guidelines for implementing double-entry bookkeeping system with accrual basis are also provided.

NoC 테스트는 온칩네트워크를 TAM으로 재사용하기 때문에 SoC 구조 기반의 여러 테스트 기법을 그대로 사용할 수가 없다. 본 논문에서는 네트워크 기반 TAM의 문제점을 크게 감소시킨 새로운 형태의 NoC 테스트 플랫폼을 소개하며 이를 이용한 NoC 테스트 스케줄링 알고리즘을 제안한다. 제안한 알고리즘은 SoC 테스트 용도로 개발된 rectangle packing 방식을 기반으로 효율적이고 체계적인 테스트 스케줄링이 가능하게 한다. ITC'02 벤치회로를 이용한 실험 결과 제안한 방법이 기존 방법에 비해 최대 $55\%$까지 테스트 시간을 줄일 수 있음을 확인하였다.
