This study investigated how much EVA which evaluate firm's value can explain hospital bankruptcy prediction as a explanatory variable including financial indicators in Korea. In this study, artificial neural network and logit regression which are traditional statistical were used as the model for bankruptcy prediction. Data used in this study were financial and economic value added indicators of 34 bankrupt and 34 non-bankrupt hospitals from the Database of Korean Health Industry Development Institute. The main results of this study were as follows: First, there was a significant difference between the financial variable model including EVA and the financial variable model excluding EVA in pre-bankruptcy analysis. Second, EVA could forecast bankruptcy hospitals up to 83% by the logistic analysis. Third, the EVA model outperformed the financial model in terms of the predictive power of hospital bankruptcy. Fourth, The predictive power of neural network model of hospital bankruptcy was more powerful than the logit model. After all the result of this study will be useful to future study on EVA to evaluate bankruptcy hospitals forecast.

As Cho-Son had difficulty in the preservation of national prestige owing to the growth or power of the western countries after the opening of a port, both government andmany pioneers promoted the enlightenment movement for our strenuous efforts. The enlightened ideology, which was founded on the ideological system derived from the korean historical conditions, was formed and developed by the influence of enlightened ideology and Japanese cultural enlightenment ; the enlightened party, which was formed after that, pushed forward the enlightenment policy actively. The enlightened parties developed the modernized system and many kinds of facilities, sent the students for studying abroad, established many schools, published magazines and so on ; further more they sent many Ryoung - Son missionaries and Shin - Sa sightseeing parties for the development of the modern commercial and industrial business and on the other hand they made efforts to develop establishment of companies and the industrial development. Thus the popular enlightenment was made diversely.

Data Envelopment Analysis/Window 모형과 Global Malmquist 생산성지수 모형을 이용한 지방의료원의 효율성과 생산성 변화 분석
양동현 한국보건행정학회 2013 보건행정학회지 Vol.23 No.1
This study empirically analyze efficiency and productivity changes of public hospitals of Korea using data envelopment analysis/Window model and global Malmquist indices model. We use the ten-year data from 2001 to 2010 of 30 regional public hospitals listed database from the Association of Korean Regional Public Hospitals. The main focuses are to reveal whether the technical inefficiency are improved as time goes by, and efficiency and productivity are affected by environmental factors. The results can be summarized as follows. First, the efficiencies of public hospitals rise in trend as time passes. Second, regional public hospitals show the different average efficiencies according to their regional type, hospital type, operational type, medicaid type, and demand and supply conditions by Mann-Whitney U-tests. Third, technical efficiency changes mainly contribute to 4.4% annual average growth rate of productivity of regional public hospitals during that period. Our findings have some policy implications. It is confirmed that there exist some environmental inefficiencies, and those inefficiencies can not be overcome through just improving the inner management system. Thus, policy and institutional changes are necessary for regional public hospitals to improve efficiency and productivity overall.

DEA-AR/AHP 결합모형을 이용한 지방의료원의 효율성 분석
양동현,Yang, Dong-Hyun 한국보건행정학회 2010 보건행정학회지 Vol.20 No.4
The purpose of this empirical study is to evaluate efficiency of the regional public hospitals, using DEA(Data Envelopment Analysis). to do this, we design a DEA-AR/AHP Hybrid model to evaluate efficiency of 34 Regional Public Hospitals. the proposed model is developed by adding Acceptance Region(AR). using analytical hierarchy process(AHP). this model is compared with those of typical DEA models. Financial data used in this study were obtained from Database of the Korea Association Regional Public Hospital and analyzed using DEA model. As a result of analysis, This study found that the DEA-AR/AHP Hybrid model was superior to those typical DEA models in determining the priority among efficient hospitals. the result of this study can provide helpful information to evaluate the efficiency of public hospitals for efficient operational management, to develop more precise measurement for the priority of the efficient hospitals.

The Japanese impeialism declared that they should establish the educational bureau which was aimed at the colonial education to control korea eternally since the Japanese annexation of Korea. And by the name of a subject of the Crown, or the domestic equalism, they tried to stike out the character and the tradition of Korea and to japanize Korean people. And in the contents of their education they pactised the differential education devided into the primary and industrial education, which is foced to rear the low working men to be necessary for the colonial control. Though the Japanese impeialism was puzzled by the resistance of the Samil Independence Movement of Korea, they claimed to stand for the cultural reign to found a stable colonial education.

마제부신은 양측 부신의 내측 변연이 융합되어 있는 드문 선천성 기형으로, 흔히 심혈관계, 신경계, 비뇨생식기계 기형을 동반하는 것으로 보고 되었다. 저자들은 마제부신과 잘 동반되는 심혈관계 기형 중 하나인 우이성체가 있는 신생아에서 초음파로 진단된 마제부신을 경험하였기에, 이를 보고하고자 한다. Horseshoe adrenal gland is a rare congenital abnormality associated with multiple congenital anomalies that may involve the cardiovascular, central nervous, and genitourinary systems. In this report, we describe the sonographic findings of horseshoe adrenal gland in a newborn with right isomerism a frequently associated cardiovascular anomaly.

The surgical technique of mitral valvuloplasty or transcatheter mitral valve (MV) replacement has been developed recently. Surgeons and interventionists require detailed anatomical information on the MV for the purpose of treatment planning. In this review, we discussed the anatomic features of the MV on CT and the method of evaluating the MV for treatment planning, as well as its preservation, for interventional procedures. 최근 들어 승모판(mitral valve) 질환에 대해 승모판 성형술(mitral valvuloplasty) 또는 중재시술을 통하여 인공판막을 넣어주는 시술(transcatheter mitral valve replacement)이 발전하고 있다. 이러한 치료 계획을 위해서는 승모판의 해부학적인 정보를 수술자 혹은 시술자의관점에서 조금 더 자세하게 알려줄 필요가 있다. 본 리뷰에서는 승모판의 보존 수술 및 중재적 시술의 치료 전 계획을 위한 승모판의 해부학 및 CT를 이용한 승모판막 주변의 평가 방법에 대해 다루고자 한다.
