The purpose of this study is to evaluate the efficiency and productivity change of Regional Public Hospitals in applying DEA and Global Malmquist productivity index and identify variables affecting productivity changes through panel regression analysis. Data used for this analysis consisted of financial statements and the managerial performance data of 34 Regional Public Hospitals from 2015 when the MERS outbreak occurred to 2020 when the COVID-19 situation was prevalent. It was found that few papers studied changes in efficiency and productivity of Regional Public Hospitals using the latest data. Therefore, the results of this study using the latest data can be used not only for management evaluation of Regional Public Hospitals, but also for the implementation of efficient provision in public medical care through government support policy directions and cooperation with private medical institutions. We found, as a result of the study, first that medical personnel, expenses, and medical revenue of regional medical centers increased every year, and medical revenue increased by 45% and cost by 32% on average in 2019 compared to 2015. On the other hand, the number of beds increased by only 4% in 2019 compared to 2015, and it seems that the external scale expansion of Regional Public Hospitals after the MERS outbreak in 2015 was actually insignificant. Second, as a result of analyzing the operational efficiency using the DEA technique, it was found that Regional Public Hospitals had shown an average of 2-4% scale inefficiency(SE) from 2015 to 2019 and the technical efficiency of Regional Public Hospitals was more affected by the scale efficiency than the pure technical efficiency. It is judged that the operational efficiency has generally improved as the medical income of Regional Public Hospitals has increased due to policy factors such as the introduction of the new diagnosis-related group(DRG). Meanwhile, the COVID-19 in 2020 had a negative impact on the efficiency indicators of all local medical centers, including the efficiency group. Third, as a result of the global Malmquist Productivity Index (MPIG) analysis, the productivity of Regional Public Hospitals had improved from 2015 to 2019, and that productivity improvement during this period had been more affected by Best Practice Change(BPC) than by efficiency change (EC). EC occurred through management efficiency improvements such as cost reduction and staff reduction, whereas technical changes were caused by continuous and long-term phenomena such as government policy changes, the introduction of the latest equipment, the application of new technologies, and the modernization of hospital facilities. In addition, the decrease in the productivity index of regional medical centers in 2020 was due to a significant decrease in the number of inpatients and outpatients at regional medical centers due to the impact of COVID-19. Fourth, the results of panel regression analysis using a fixed model showed that medical personnel and costs negatively had effected to the change in the productivity index. In order to improve productivity, it is necessary to reduce costs due to reasonable manpower management and appropriate personnel cost, and to find ways to efficiently utilize manpower through attracting patients and increase medical profits. Based on a result of the above study, the following implications could be derived to improve the operational efficiency and productivity of Regional Public Hospitals. Regional Public Hospitals should adjust the size according to their environmental characteristics and maintain balanced resource input and allocation to improve the performance efficiency and productivity. Also, the central and local governments need to develop the policies supporting Regional Public Hospitals that can continue even after the COVID-19 situation is over. It is the time when the central government and local governments need an active support policy for the chronic deficit problem of local medical centers and the external expansion of hospital beds, medical personnel, and medical equipment. In the face of a national crisis such as the recent COVID-19, the role and necessity of Regional Public Hospitals as a provider of public health care to local residents is being emphasized more and more. The results and implications of this study will be suggestions for the expansion plan of public health currently being discussed in the government.

The purpose of this study is to find the success factor of Dongbu Insurance`s home-based call center as a service innovation model. Nowadays, home-based call center spreads widely all over the wolrd. Dongbu Insurance home-based call center case was analyzed using Suh & Kim(2012)`s 「home-based call center fit model」 which consists of four factors such as human resource, hardware resource, organizational characteristics and job characteristics. As a result, it was found that made Dongbu Insurance`s home-based call center successful wrere its employee autonomy, organizational support, customer centric service level management and home-based specialist training programs. The benefits of Home-based call center model are high quality jobs, cost reduction, better customer service, and more women employees. We hope that the result of this case study provides practical guideline for the companies which try to adopt Home-based call center model and a wider perspective for the researchers.

Recently, CSR and Business ethics are the most important factors in terms of sustainability of business. SHINSEGAE has accompanied business ethics with many activities for 13 years in Korea. This paper shows the SHINSEGAE``s various legal and ethical behavior practices through the ISO 26000 Criteria and Malcolm Baldrige Model. They conducted systematic programs and various activities about legal and ethical behavior. Through this case, many corporations that are pursuing legal and ethical behavior can have a role model and benchmarking issues. This study has several implications for business ethics. The first, every corporation must have the active preparation plans with the illegal and unethical activities. Second, they must be able to control the internal and external unethical activities throughout continuous monitoring process. Finally, corporation must have the system that can be assured employees legal and ethical behavior.

본 연구는 공급기업과 구매기업의 특성을 함께 가지는 벤처 제조기업들을 대상으로 적절한 경영성과를 창출하기 위한 공급체인 설계 시사점을 제공할 목적으로 실시되었다. 연구결과에 의하면 공급체인 유형이 공급체인 방향성 구축에 미치는 영향력에서 정보 활용성이 커질수록 외부 지향적 공급체인 구축에 영향력을 미치고 장기적 관계, 가격 이외의 기준에 의한 공급기업 선정 방침은 공급체인의 내부 지향적 구축에 영향력을 가지는 것으로 나타났다. 한편 단순한 공급체인의 지리적 확대는 공급체인 방향성의 외부 지향에 영향력을 가지지 못하는 것으로 나타났다. 마지막으로 재무성과는 공급체인이 내부 지향적일수록 높은 성과를 가지며 적절하게 공급체인에 대한 환경과 전략을 연계한 기업에서 높은 성과 수준을 보이는 것으로 나타났다. This research addresses the effective designing policy of supply chain to enhance the corporate performance. We suggest the research model including design factors such as type of supply chain, locational dispersion and direction of supply chain, and business performance. We assume that the design factors of supply chain are interlinked and affect business performance of the corporate in the supply chain. These hypotheses are tested empirically. Consequently, the results are summarized as follows. First, as the level of information application was higher, the effectiveness of establishment of external-oriented supply chain was higher. Second, there was a negative relationship in between geographical diversification and external-oriented direction of the supply chain. Third, the supply chain pursuing a higher externality showed higher financial performances significantly. Also the results showed that the firms well aligned with environment strategy had high performances in the four BSC(Balance Score Card) category except an internal process performance.
