본 연구는 의료에 대한 관심의 증가로 병원에서 도입하고 있는 전자의무기록 시스템의 성과에 대한 연구를 수행하려고 한다. 전자의무기록 시스템은 병원 업무 처리를 신속하게 할 수 있고 환자와 의료진과의 원활한 커뮤니케이션을 지원할 수 있다. 그러므로 본 연구는 전자의무기록 시스템의 특성을 지각된 이익, 호환성, 이용 편리성으로 분류하고, 신뢰를 정보신뢰와 기술신뢰로 분류하였다. 또한 전자의무기록 시스템의 특성, 신뢰, 성과와의 관련성을 살펴보기 위하여 연구모형을 설계하였다. 전자의무기록 시스템을 도입한 병원에 근무하고 있는 의사, 간호사, 직원들을 대상으로 설문조사를 수행하였으며, AMOS 7.0을 활용하여 경로분석을 수행하였다. 분석 결과, 지각된 이익, 호환성, 이용 편리성은 정보신뢰와 기술신뢰에 긍정적인 영향을 미치고 있었으며, 정보 신뢰와 기술신뢰는 전자의무기록 시스템의 성과에 긍정적인 영향을 미쳤다. 또한 지각된 이익과 호환성은 전자의무기록 시스템의 성과에 긍정적인 영향을 미치고 있었지만 이용 편리성은 긍정적인 영향력을 가지지 못하였다. 본 연구의 결과는 전자의무기록 시스템을 도입하고자 하는 병원에게 의미 있는 시사점을 제공할 수 있을 것이다. We examine a performance of electronic medical record which is adopted by the hospitals. Electronic medical record (EMR) can quickly handle tasks of the hospital and support communications in the relationships between patients and medical workers. This study investigates the effects of EMR characteristics(perceived benefit, compatibility, and ease of use) and EMR trust(information trust, and technological trust) on the EMR performance. We design a research model in order to investigate the relationships among characteristics, trust, and performance of EMR. This study conducted the survey of doctors, nurses, and medical workers which work in the hospital adopting EMR. The results of path analysis are as follows. First, perceived benefit, compatability, and ease of use had a positive effect on the information and technological trust. Information and technological trust had a positive influence on the EMR performance. Perceived benefit and compatability had a significant effect on the EMR performance, but ease of use had no effect on their performance. This study can provide valuable guidelines to hospitals which are going to introduce the EMR into the hospitals.

The purpose of this research is to identify the impact factors and the moderator of incentives of knowledge transfer process. Impact factors of knowledge transfer consist of three distinct characteristics: Individual characteristics(self-directness, individual information capability), cognitive community characteristics(trust, community-identity), quality characteristics(quality of knowledge, quality of community-construct). The incentives of knowledge transfer consist of psychological incentive and physical incentive. Knowledge transfer consists of three distinct process: knowledge acquisition, knowledge sharing and knowledge use. To verify we conducted a survey and collected data from 345 members of online community. Data were analyzed to test the hypotheses by SPSS 17.0, and LISREL 8.54. The results of this study founded that individual information capability, trust, community identity, quality of knowledge, and quality of system were statistically significant in knowledge transfer, however, self-directness was not statistically significant in knowledge transfer. Interact effect of knowledge acquisition and physical incentive on knowledge use was statistically significant. This study integrated and verified impact factors of individual characteristics, cognitive community characteristics, and characteristics of quality. This study proposes that existing communities can revitalize by promoting trust, community identity, quality of knowledge, quality of community construct, and incentives.

The purpose of this paper is to examine the relation between the investment opportunity set and capital structure, dividend policy, and executive compensation policy variables, as a major corporate policy. Using the data of 150 listed firms from 1987 to 1996, the factor analysis has been conducted in order to classify as growth firms and non growth firms, then the regression analysis has been used between corporate policy variables and the investment opportunity set. The results of empirical test indicate the investment opportunity set has a significantly negative relation to debt financing. This means because equity financing controls the potential underinvestment problem associated with risky debt, firms with more growth options have lower debt/equity ratios than nongrowth firms. This relation is consistent with contracting arguments and inconsistent with signaling hypothesis. Also as expected, firm size is positively related to the use of debt financing. The dividend policy variable has a negative relation with the investment opportunity set. This provides qualified evidence that growth firms pay lower dividends than nongrowth firms due to lower free cash flow. Firm size is significantly positively related to dividend payout. The results for compensation policy present that growth firms pay higher levels of remuneration to their executives than nongrowth firms. The estimated coefficient on investment opportunity is significantly positive on the regression of compensation.

기업의 자본조달 행태에 관한 실증적 연구

This paper is an empirical test of the corporate financing behavior on the basis of the pecking order hypothesis in the capital structure by examining of firms that actual sales growth exceeded sustainable growth. According to the pecking order theory, firms typically employ a pecking order of financing choices, using internal equity before the issuance of external debt, followed by the issuance of external equity. Using the data of 363 listed firms from 1987 to 1988, contingency table analysis and multinomial logit analysis performed in this paper. The results are as follows: 1. The faster firms are growing, the more they use up available internal financing and, thus, must raise funds externally. 2. The firms with lower asymmetric information tend to raise the majority of their funds externally, with debt being the primary choice. When external financing is required, firms increase debt financing first, followed by new equity. 3. The rate of sales growth and the size of the company have an important bearing on the choice of financing. These results provide indirect support for the pecking order theory since it appears that firms use available internal financing, then debt, then new equity to finance growth.

기업의 인수합병에 있어서 시너지 효과와 소유구조의 영향

This paper attempts an integrated explanation of the wealth experience of the bidder and target shareholders in terms of the synergy and ownership structure as a kind of agency problem while controlling for the bid dynamics variables. The synergy effects in mergers and acquisitions(M&A) include operational, managerial and financial synergy. The ownership structure is the status of the shares showing to the extent of equity for the interest parties. The synergy effects and ownership structure impact significantly on shareholder returns. Through the literature research, the effects of these factors on the abnormal returns to the shareholders are as follows; 1) the positive effect of the size of the synergistic benefits from M&A suggests the smaller the target the greater the wealth gains to target and bidder shareholders, but the industry relatedness is not significant for abormal returns of shareholders and does not lead to operational synergy. 2) the managerial efficiency is the positive impact on target shareholder returns and supports the managerial synergy hypothesis, but it is the significant negative coefficient to the bidder returns. 3) as the proxies for the financial synergy, the complementarity of the mismatch of resources and growth opportunities is the positive effect and a source of added value in mergers, but the difference between bidder and target in the ratio of liabilities to assets is the negative impacts on both shareholders groups. 4) although not significant, the managerial shareholdering has a positive coefficient to shareholder wealth gains. 5) large shareholdings decrease abnormal returns to both bidder and target shareholders whereas bidder toehold decreases the returns to target shareholders.
