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.

보유하고 있는 자원이 소수로 제한적이고 환경이 열악한 중소 제조 기업은 자신의 핵심 역량을 발굴하여 선택하고 집중함으로써 경쟁력을 확보해 나가는 것이 기업 경영의 성장과 지속성을 유지해 나가는 지름길이다. 이러한 관점에서 중소 제조 기업의 특성에 맞는 핵심 역량을 도출하고 우선순위를 결정하는 것은 매우 중요한 것이다. 본 연구에서는 경기도에 소재하고 있는 중소 제조 기업을 대상으로 핵심 역량을 도출하고 핵심 역량 모델을 제시하고자 한다. 또한 애로 역량을 동시에 파악함으로써 중소 제조 기업이 제한된 자원을 집중하여 시급하게 우선적으로 강화해야 할 역량을 밝혀내고자 한다. 기존의 많은 연구가 기업의 업종, 업력, 규모 등의 분류 기준에 의해 이루어진 것과 달리 기업의 고객유형별, 납품방식별, 생산 프로세스별, 전략유형 등의 기준에 따른 핵심 역량과 애로 역량을 파악하여 현실적이고 실용적인 중소 제조 기업의 경쟁력 강화 방안을 제시하고자 한다. 결과적으로 기술 역량과 CEO 역량이 가장 시급하고 중요하게 육성되어야 할 역량으로 파악됨에 따라 이에 대한 다양한 육성방안 및 프로그램 제공이 필요하다. This research suggests the approach method to preferentially search and improve core competencies of small and middle manufacturing companies in Korea. The middle-small size companies that have very limited internal resources, should concentrate on their core competencies for growth and sustainability of business. In this scope, it is the most important thing to deduct the core competency’s order of priority for reinforcement. In first, we deduct the core competencies, Secondly suggest the model of core competency for the middle-small size companies. Additionally as we deduct the bottleneck competencies of them, we are going to determine the order of priority through the comparison of core and bottleneck competencies. In this process, we deduct core and bottleneck competencies by using the differentiated criteria of customer, manufacturing, manufacturing process and strategy types. But much studies were accompanied by company size, types of business, period of business and so on. But we suggest the practical approach for reinforcement of competitiveness. Consequently, the results show the practical implications and the order of priority for competencies reinforcement.

The damage mechanism of Cr₂O₃ plasma coated soda-lime glass and uncoated glass by steel ball particle impact was analyzed in this study. And the shape variation of the cracks was investigated by stereo-microscope according to the impact velocity and steel ball diameter.<br/> In order to improve the damage reduction effect by Cr₂O₃ coating layer, crack size was measured and surface erosion state was observed for both of two kinds of specimen after impact experiment. And the results were compared with each other. The 4-point bending test was performed according to ASTM D790 testing method to evaluate the effect of coating layer for bending strength variation. As a result, it was found that the crack size of Cr₂O₃ coated specimen was smaller than that of uncoated one, because of the impact absorption by interior pores in the coating layer and the load dispersion by the structural characteristic of the coating layer. For the specimens subjected to the steel ball impact, the bending strength of coated specimen was higher than that of uncoated specimen.

While the aggregate demand for electronic goods has nationally been on the constant decrease since 2012, retail distribution dealing in electronic goods has become supersaturated and distributors are fiercely competing with one another to make a sale and attract customers. To meet this challenge, electronic goods distributors try to improve store management and make better performance. Therefore, the purpose of this study is to determine the causal relationships among the qualitative factors affecting performance of stores in search of a breakthrough in managing electronic goods retail stores. The theoretical framework of the Balanced Scored Card (BSC) suggested by Kaplan and Norton was used to determine the causal relationships. This study aims to make organizational members understand an efficient work process and proceed in one direction with the objective of improving performance. Checking the value creation process model would help electronic goods distributors establish an efficient management strategy. A survey was conducted in 267 persons at 72 retail stores of S Electronics. The partial least squares(PLS) path model, one of the structural equation models, was used to determine the relationships. The causal relationships among the concepts directly and indirectly affecting performance of electronic goods retail stores were reviewed. The first attempt was made to check the value creation process model for electronic goods retail stores.

Until now, many kinds of treatment modalities for mandibular angle fractures have been proposed. But among them, the semi-rigid fixation using miniplates has become a most popular procedure due to its simplicity and good clinical results in nowadays. When we use miniplates according to Champy s ideal osteosynthesis line principles for mandibular angle fracture treatment, we generally perform reduction and fixation procedures under the condition of maxillomandibular fixation(MMF) using arch-bars. But in so doing, due to various reasons, we occasionally observe gapping or torqueing of inferior border of mandibular angle after completion of miniplate fixation. In contrast to MMF state, we can observe intimate reduction of inferior border of mandibular angle due to compressive force and gapping of superior border due to tensile forces during wide mouth opening state. So we developed a new technique which uses bone reduction forceps(or modified towel clips) as a temporary fixation device during wide mouth opening state for intimate reduction and stability along the entire fracture line. By applying this new technique for mandibular angle fracture treatment, it was possible for us to perform easy and accurate miniplate fixation for last 1 year period with clinical success. This article presents some case reports of mandibular angle fracture patients who were treated by this new technique and discussions about the reliability and advantages of this technique.
