컴퓨터 소프트웨어는 이제 우리의 일상적인 삶에서 필수불가결한 요소이며 시스템의 운용에 중요한 요인이 되었다. 최근에 들어서는 소프트웨어 비용이 하드웨어 비용을 초과하게 되면서 소프트웨어를 개발하는데 필요한 비용과 더불어 소프트웨어 고장에 의한 비용의 중요성이 더 커지게 되었다. 본 논문에서는 Non-Homogeneous Poisson Process(NHPP)에 기초한 소프트웨어 비용 모형을 제안하려고 한다. 개발초기단계에서 출시 전까지의 소프트웨어 개발비용과 테스트비용, 출시이후의 보증기간동안의 제반비용, 소프트웨어 고장에 의한 위험비용 등을 포함하는 소프트웨어 비용 모형을 제안하고 소프트웨어의 최적 출시시기를 결정하는 효과적인 정책을 제시하려고 한다.

This paper presents an efficient software reliability testing method for the model based auto-generated code and reify a dynamic test procedure. The benefits of executing the model-based each static/dynamic reliability test before the code-based static/dynamic reliability test are described. Also, The correlations of code/model based reliability test are demonstrated by using model testing tool, Model Advisor and Verification and Validation, and the code testing tool, PolySpace and LDRA. The result of reliability test is indicated in this paper.

This paper aims to empirically analyze the factors of difference in trust level for Internet-only bank by age groups. The purpose of this study is to provide clues and a research data in developing differentiation strategies that can increase consumer's trust by age group. In this study, above all, the financial consumer group was divided into the 2030s and 4050s based on age. The study explored the trust determinants of the two groups and compared the differences between the two groups using a multi-group analysis method. As results, in all age groups, financial consumer's trust was seen as a determinant of convenience, security and benefit of financial transaction costs. The difference of the determinant of trust between 2030s and 4050s occurred in the factor of benefit. Moreover, it reconfirmed that consumer's trust is later strongly extended to relationship commitment. These findings suggest that trust is of paramount importance to the Internet-only bank, whose market competition will intensify in the future.

In this paper, MOS-Capacitor and MOSFET devices with a Low Level Leakage Current of oxide thickness, channel width and length respectively were to investigate the reliability characterizations mechanism of ultra thin gate oxide films. These stress induced leakage current means leakage current caused by stress voltage. The low level leakage current in stress and transient current of thin silicon oxide films during and after low voltage has been studied from strss bias condition respectively. The stress channel currents through an oxide measured during application of constant gate voltage and the transient channel currents through the oxide measured after application of constant gate voltage. The study have been the determination of the physical processes taking place in the oxides during the low level leakage current in stress and transient current by stress bias and the use of the knowledge of the physical processes for driving operation reliability.

The most widely used data mining technique for big data analysis is to generate meaningful association rules. This method has been used to find the relationship between set of items based on the association criteria such as support, confidence, lift, etc. Among them, confidence is the most frequently used, but it has the drawback that we can not know the direction of association by it. The attributably pure confidence was developed to compensate for this drawback, but the value was changed by the position of two item sets. In this paper, we propose four symmetrically and attributably pure confidence measures to compensate the shortcomings of confidence and the attributably pure confidence. And then we prove three conditions of interestingness measure by Piatetsky-Shapiro, and comparative studies with confidence, attributably pure confidence, and four symmetrically and attributably pure confidence measures are shown by numerical examples. The results show that the symmetrically and attributably pure confidence measures are better than confidence and the attributably pure confidence. Also the measure NSAPis found to be the best among these four symmetrically and attributably pure confidence measures.

현재 한국전기연구원에서는 년간 약 1,000여대 이상의 차단기류에 대하여 사용전 검사 시험을 실시하고 있다. 차단기류의 사용전 검사 시험 항목은 개폐 특성에 대한 검증이 주를 이룬다. 현재 사용하고 있는 차단기 개폐특성 시험 설비는 약 20여년을 사용하여 보수가 필요한 시점에 도달하였다. 본 논문에서는 차단기류의 개폐특성 시험에 사용하던 차단기 특성 시험 시스템의 단점을 보완하여 시험의 신뢰성 및 사용자 편의성을 향상시킨 시험 시스템을 개발하고자 한다.

프랑스에서는 사르코지 정부 출범 전후에 여러 가지 개혁 동향들이 발표되어왔다. 프랑스는 오래 전부터 대학제도의 불합리성을 잘 알고 있었다. 20년 전부터 3번에 걸쳐 대학제도개혁을 시도하였으나 번번이 실패한 바 있으며, 지금도 대학의 전반적인 개혁이 시급한 문제로 대두되고 있다. 특히 수요자인 대학생에게 신뢰를 주지 못한 것이 대학의 가장 큰 문제점으로 지적되어왔다. 피용 내각의 고등교육제도개혁 방향을 소상히 살펴보기에 앞서 먼저, 프랑스 정부가 시급히 개혁을 추진하지 않을 수밖에 없었던 이유를 진단해 봄으로써 프랑스 고등교육의 문제점을 심도 있게 관찰해 보도록 한다.

The purpose of this study was to examine whether corporate sports marketing strategy using professional teams changes corporate image. In particular, this study was intended to analyze the effects of origin and corporate reputation on the change of corporate image in the process of persuading corporate image. Finally 211 effect data were secured by pre-test and post-test. The change of corporate image and the moderating effect of origin perception and corporate reputation were analyzed. The results were as follows. First, corporate trust image and social contribution image showed statistically significant increase. Second, corporate image had a difference before and after the test according to origin perception and after the test, corporate trust image and social contribution image were increased. Third, corporate image had a difference before and after the test according to corporate reputation. After the test, corporate trust image and social contribution image were increased and trust image confirmed the mediating effect according to corporate reputation. Based on the findings, this study suggests that corporate sports marketing strategy using professional teams has an effect on the persuasion of corporate image. Moreover, it demonstrates that the strategy is an important marketing tool to change consumers' corporate image.

This research focuses on the effect of consumer's innovativeness and the trust in other domain affecting the intention to use mobile payment services. The result of this paper reveals that consumer's innovativeness has both a direct impact on the intention to use mobile payment services and a indirect impact. Relative advantage and image play a mediating role between consumer's innovativeness and the intention to use mobile payment services. Moreover, the study reveals that the trust in other domain not only directly affects on the intention to use mobile payment services but also indirectly affects by mediating relative advantage, image, and perceived risk. This study indicated that a customer's established trust in other domain influences his or her trust in mobile payment services. Electronic payment service providers should consider that the trust-building process encompasses other domain as well as mobile relationships. And electronic payment firms should do their best to reduce customers' perceptions of risk.
