최근 소셜 네트워크 서비스는 소비자와의 관계 마케팅 확산 및 확장을 위한 중요한 채널로 인식되며 많은 관심을 받고 있다. 기업이 온라인 환경에서 성공하기 위해서는 기업과 고객 사이의 관계 구축뿐만 아니라 고객들 간의 관계에 초점을 맞출 필요가 있다. 본 연구에서는 페이스북 팬 페이지에 참여하는 사용자들 사이의 네트워크를 분석하여 기업의 비즈니스 성과에 고객 간 네트워크의 구조적 특성이 미치는 영향을 실증적으로 분석하였다. 이를 위해 네트워크 데이터는 코스피 상장 기업 가운데 페이스북 팬 페이지에 100개 이상의 게시글을 올린 54개 기업으로부터 수집하였으며, 수집된 네트워크 데이터는 각 사용자를 노드로 하고 동일한 마케팅 활동에 대해 참여한 사용자간의 관계를 링크로 한 원모드 비방향 이진 네트워크(one-mode undirected binary network)이다. 본 연구에서는 이러한 네트워크 데이터를 핸들링하여 사용자들 간의 활동 관계를 분석할 수 있는 네트워크 지표(밀도, 글로벌 클러스터링 계수, 최단거리평균, 직경)를 도출하였으며, 이러한 고객 간 네트워크의 구조적 특징을 파악할 수 있는 지표와 기업의 과거실적(순이익), 그리고 미래 예측성과(토빈의 Q) 간의 관계를 분석하였다. 본 연구는 학문적 관점에서 소셜 미디어 채널을 비즈니스 관점에서 연구하려는 연구자들에게 소셜네트워크분석 방법을 통한 새로운 접근법을 제시한다. 실무적인 관점에서 본 연구는 소셜미디어를 통해 마케팅 활동을 수행하려는 기업의 관리자들에게 네트워크의 지표를 이용한 지능형 마케팅 서비스를 수행할 수 있는 토대를 제공할 것으로 기대한다.

With the rapid growth of the internet, electronic commerce has become accepted as one of the major purchasing channels for consumers. As more and more consumers search for and purchase products through the internet, intra-industry competition of electronic commerce has become fierce. Therefore, electronic commerce service providers pay attention to factors that prevent existing customers from leaving there services in the service failure situation. In this regard, electronic commerce service providers should make service recovery efforts for consumer recovery satisfaction after service failure. In this study, we suggest that procedural justice, interactional justice, distributive justice and authenticity have positive impacts on recovery satisfaction. In addition, we also propose that involvement plays moderating roles in the relationships between procedural justice, interactional justice, distributive justice, authenticity and recovery satisfaction. We collected empirical data for this study over a period of two weeks from subjects who had service failure recovery experiences through electronic commerce. A total of 224 complete and valid responses were obtained. We carried out data analysis using a two-step methodology with SPSS 20.0 and SmartPLS 2.0. The first step in the data analysis was to establish the internal consistency, convergent validity, discriminant validity of the constructs. In the second step, we examined the structural model. The empirical results support the proposed model and partly identify the moderating effect of involvement differences. The moderate effect results show that procedural justice, distributive justice and authenticity have different impacts on recovery satisfaction in two groups. Cognitive factor such as the procedural justice and distributive justice have stronger impacts on recovery satisfaction in the high-involvement goods than in the low-involvement goods, while emotional factor such as authenticity has a stronger impact on recovery satisfaction in the low-involvement goods than in the high-involvement goods. We expect that this result will provide researchers and managers who are interested in electronic commerce service failure recovery with useful theoretical and practical implications.

신뢰성 수명예측 도구 Sherlock을 이용한 큐브위성용 임무보드의 고장 메커니즘별 수명예측

극초소형 위성으로 분류되는 큐브위성의 경우, 저가/단기간 개발목표 충족을 위해 일반적으로 진동 및 열 환경 규격을 만족하는 상용부품을 선정하여 제작하고 최소한의 검증시험을 통해 발사 및 궤도 운용을 실시한다. 하지만 제한된 회수로 지상에서 실시된 환경시험만으로 장시간에 걸친 궤도상 열진공과 같은 물리적 부하 환경에 노출된 임무보드의 신뢰성을 보장할 수 없다. 본 논문에서는 현재 자동차 분야에서 탑재 전자기기 신뢰도 예측에 폭넓게 활용중인 신뢰성 수명예측 상용도구인 Sherlock을 적용하여 큐브위성용으로 제작된 전자보드를 대상으로 발사 및 궤도환경에서의 고장 메커니즘 별 수명예측 및 임무기간동안의 신뢰도를 분석하였다. A cubesat classified as a pico-satellite typically uses commercial-grade components that satisfy the vibration and thermal environmental specifications and goes into mission orbit even after undergoing minimum environment tests due to their lower cost and short development period. However, its reliability exposed to the physical environment such as on-orbit thermal vacuum for long periods cannot be assured under minimum tests criterion. In this paper, we have analysed the reliability and life prediction of the failure mechanisms of the cubesat mission board during its service life under the launch and on-orbit environment by using the sherlock software which has been widely used in automobile fields to predict the reliability of electronic devices.

  To resolve the problem on lack of house and provide low price land. city development business brought great positive effects. such as. stabilization of housing problem. improvement of welfare. enhanced infrastructure and re-investment of profit from development for the balanced land development. However. the increase of housing diffusion rate and improved level of people"s life. this business had reached to its limit point and the new form of development method was required. Meanwhile. IMF crisis caused real estate developer difficulty of financing and large sized land was hardly sold. In new cities like Bundang and llsan, which was developed according to the land development project. a lot of sold land were developed according to their altered "purpose of land" and this became a problem. land which was sold as a commercial purpose had a long delay in development (or delayed on purpose) to switch to the purpose of residing and had been developed. This conversion of purpose cause the excess of pre-planned infrastructure and problem of self sufficiency. Therefore, after the occupation of house still there were no facilities and residents complained about that.<BR>  Public-private sector cooperation model PF business would provide facilities in time to residents in addition. public sector would obtain public welfare and private sector would not be pressured by financing. This is to use creativity and efficiency of both sides to develop real estates.

1. CONTENTS (1) RESEARCH OBJECTIVES In order to identify the factors determining the success of public-private partnership project financing by survey to the experts. Analysis on the importance of those factors to identify the core factors that affect the performance of public-private partnership project financing. (2) RESEARCH METHOD A survey was conducted to the employees in charge of the public-private partnership project financing through the AHP empirical analysis. The analysis tool for the research was the team version 11.0 of Expert Choice 2000(EC2000) program and Microsoft Excel in order to synthesize the results of the survey. (3)RESEARCH FINDINGS In the existing studies, the topic are mostly the ways of improvement for the legal and systematic problems or the measures to activate the public-private partnership project financing. However, this study is differentiated from the other in a sense that it concerns an empirical analysis on the determining factors of the public-private partnership project financing using the AHP statistical method. 2. RESULTS The results of the empirical analysis are as follows. First, the business environment such as the change in the real estate policies was an important factor for the success and performance of the public-private partnership project financing. Second, in order do effectively carry out the public-private partnership project financing, the public and the private sectors should clarify their roles. Also, the CEO and responsible employees should be highly interested as well. Third, in the settlement management, the disposal by Reits Fund(Real estate finance) was the most preferred method. This shows that disposal by Reits Fund was the most preferred among the types of SPC settlement.

X-band antenna has been widely used to effectively transmit the high resolution image data from the observation satellite to the ground station. To achieve above mission, X-band antenna is mainly composed of the 2-axis gimbal system using stepping motors and gears. However, the micro-vibration induced by the stepping motor actuation and the imperfect gear teeth alignment during this on-orbit operation is the main source of image quality degradation. In this paper, X-band antenna combined with a blade gear for micro-vibration isolation was suggested and investigated. The structural safety of the blade gear with low rotational stiffness was confirmed by structure analysis based on the derived torque budget. The isolation performance of the X-band antenna with the blade gear was verified through micro-vibration measurement test using the dedicated micro-vibration measurement device proposed in this study.
