With the application enlargement of RFID technology in the field of logistics, it is needed to analyze the relation adoption factors of RFID with logistics performance. That is, this study aims at analyzing how RFID adoption would give an effect to logistics performance in logistics company, stating its implications. More specifically, this study tests empirical relation of CEO's support, technical competence, trading partner, compatibility, relative advantage and logistics performance of applying RFID in logistics company. Based on previous studies which are related to RFID in the field of SCM, logistics, distribution and manufacturing, this study established research model and hypothesis, and surveyed employees of logistics company. To analyze the data, exploratory factor analysis, reliability analysis, confirmatory factor analysis and structural equation model were applied. The results are follows. Applying RFID in logistics, CEO's support and trading partner gives significantly positive effect to logistics performance. But compatibility and relative advantage do not give meaningful effect to logistics performance. Additionally, though technical competence does not have statistical significance to logistics performance, it is necessary to consider it can have meaningful influence on logistics performance substantially.

The purpose of this study is to identify the determinants of new venture performance in the view of integrated research framework and to investigate key determinants of superior and inferior ventures. We propose the integrated new ventures performance model which is composed of entrepreneur, organization/resources, industrial environment, strategy/foundation process and availability of supporting systems as corresponding variables to new ventures performance. The superior venture performance is affected mainly by entrepreneur's managerial ability and industry expertise, but the inferior by resources and management strategy. Though this study has limitation of small sample, limited questionnaire and performance measure, it has contribution of identifying key determinants of new venture performance with the integrated frame of study.

Recently, the mobile game industry is explosively extending and advancing. Nevertheless, although research on IT acceptance has been actively performed, the effective studies have not been accomplished in the acceptance of mobile game. This study, therefore, explores the factors affecting customer's intention to use mobile game. Five external factors(service quality, social influence, instant connectivity, self-innovativeness, and self-efficacy) are proposed to test the several hypotheses. The factors are classified to three dimensions - system, individual, and society. The research model is based on various studies on TAM(Technology Acceptance Model) and mobile service. A survey of mobile game users collected 270 cases, and we used 261 cases for statistical analyses. The analyses show that service quality, instant connectivity, self-innovativeness, and self-efficacy have an indirect effect on the intention to use through perceived usefulness and perceived ease of use. We provide the important factors that should be focused on when an enterprise develops and promotes new mobile game products.

The need for estimating the real transaction price of land is increasing in order to build foundation for transparent land transaction and fair taxation. This study looked into the applicability of cokriging combining real transaction price of land, altitude and gradient for effective price estimation on the points where the real transaction does not take place in the course of using the real transaction price of land. The real transaction price of land have been estimated using the real transaction materials of Yeongcheon, Gyeongsangbuk-do from January 2012 to June 2014, and the results have been compared with the estimation results of ordinary kriging. As a result of analyzing the mean error and root mean square error (RMSE) of the estimated price and 2,575 verification points, it was found that compared to ordinary kriging, cokriging results were more effective in terms of the real transaction price estimation and actualization. The reason that cokriging is more effective in the real transaction price estimation is because it takes account of altitude and gradient which are the forces influencing the land value.

Recently, online environment is actively used so it will be needed to identify the factors influencing satisfaction for continuous success. In this paper, we explain the users' satisfaction of online purchasing IT and verify them through the empirical analysis. We select basic variables from TAM (Technology Acceptance Model) and add specific variables from former research about user's trait. We chose satisfaction, perceived easiness, perceived usefulness, regret and maximizing tendency. Data collected from 150 user who had prior experiences with online purchasing IT were empirically tested against the research model using partial least square (PLS). The results show that perceived easiness, perceived usefulness and regret are significantly related to satisfaction and maximizing tendency has positive impact on perceived easiness, perceived usefulness and regret significantly.

주식시장에서 환율위험프리미엄의 존재유무는 기업의 투자 및 자본조달, 외환헤징재무활동, 개인의 투자전략 등에 중요한 영향을 미치게 된다. 본 연구에서는 차익거래모형을 이용하여 우리나라 주식시장에서 환율위험노출을 측정하고, 그 환율위험이 시장에서 보상되는 위험인가를 검정한다. 전체 표본기간은 1980년부터 1998년까지이며, 외환자유화와 자본시장 개방이 본격적으로 이루어진 1992년 이전과 이후를 하위기간으로 구분하여 분석하였다. 표본하위기간의 설정, 다각적인 환율위험요인 측정, 다양한 모형설정과 복수의 통계추정방법의 적용 등을 통하여 환율위험 프리미엄의 유무에 관련된 신뢰성있는 결론을 도출하고자 하였다. 1980년대 표본전기 하위기간에는 주식시장에서 통계적으로 유의한 환율위험노출을 확인하기 어려웠으나, 외환자유화와 자산시장개방이 본격화된 표본 후기 하위기간에는 뚜렷한 환율위험 의 존재를 확인할 수 있었다. 후기 하위기간을 대상으로 시장위험과 실효환율위험만을 포함한 차익거래모형을 적용하였을 때에 통계적으로 유의한 환율위험 프리미엄이 확인되었다. 그러나 달러환율과 엔화환율위험을 별개의 환율위험으로 설정한 경우 각 환율위험에 개별적으로나 결합적으로 통계적으로 유의한 위험프리미엄을 발견하지 못하였다. 더구나, 실효환율위험에 추가하여 산업생산위험, 인플레이션위험, 기업부도위험 등의 기본적 경제요인 위험을 함께 통제변수로서 포함하여 차익거래모형을 적용하였을 때에도 환율위험 프리미엄은 존재하지 않았다.

이 논문에서는 자산의 수익률과 공통요인이 시간가변적 변동성을 갖는 경우의 APT를 검증하고자 시도하였다. 이를 위하여 1980년 1월부터 1995년 12월까지의 17개업종별 포트폴리오 수익률로부터 주성분분석에 의하여 4개의 공통요인을 추출하였다. (이중 첫 번째 요인은 동일가중 시장수익률과 거의 1에 가까운 상관성을 갖고 있으므로, 추출된 첫 번째 요인 대신에 시장수익률을 사용하였다.) 17개 업종별 포트폴리오에 대한 ARCH모형을 추정한 결과, 12개 포트폴리오의 수익률이 조건부 이분산성을 보이고 있다. 또 네 개의 공통요인 중 시장수익률을 포함한 3개의 요인은 뚜렷한 조건부 이분산성을 보이고 있다. 따라서 요인위험--즉, 공통요인에 대한 개별자산의 민감도$({\beta}_{ij})$--은, 개별자산과 공통요인의 상관계수가 일정하다고 가정하여, ARCH모형에 의해 측정된 자산 및 공통요인의 시간가변 표준편차로부터 계산되었다. 이와 같이 계산된 요인위험에 대하여 어느 정도의 위험프리미엄이 주어지고 있는가는 일반화 적률법(GMM)에 의하여 추정하였다. 그 결과, APT의 추정에 사용된 4개의 공통요인 중 시장수익률을 포함한 3개의 요인에 대하여 유의한 위험프리미엄이 추정되었다.

This research focuses on what factors determine firm's decisions on R&D outsourcing and how R&D outsourcing affect R&D performance. In recent years many firms outsource R&D activities instead of internalizing it. Thus, further investigation is necessary to find out this recent trend. Based on several theoretical background the study developed three determining factors of R&D outsourcing which are transactional level, firm level, and risk level. Transactional level composes of independent variables such as R&D cost saving, asset specificity and uncertainty which mainly comes from Transaction Cost Economics theory. Firm level composes of openness to technology from outer source, R&D capability, and outsourcing experience. Risk level composes of technological risk, cost-related risk and managerial risk. The result shows that R&D outsourcing is significantly related to cost saving aspect, low asset specific firms, firms without solid technological background, firms which are open to external technology, firms with other types of outsourcing experience, and firms which take technological risks. However, proposed relationship between degree of R&D outsourcing and R&D performance found out to be insignificant. This research is contribute to the field of outsourcing study since it will give guidance to managers who need to make strategic decisions on R&D outsourcing activities.
