This paper analyzed the efficiency of 50 education franchise brands having more than 100 franchisee from the perspective of franchisees. For this purpose, candidate set for input and output variables of the DEA model has been formed and the partial efficiency scores have been calculated based on Tofallis' profiling method. Then we conducted an correlation analysis to these partial efficiency scores, resulting in the input variable as initial investment, as well as output variables as annual average sales amount, number of franchisee stores, promotion budget, net profit, number of new member stores, brand age, number of employees, and total amount of capital. Our findings are as follows. First, Out of 50 brands, only 8 brands have been turned out to be efficient in terms of technical efficiency of the CCR model. In terms of pure technical efficiency of the BCC model, 19 brands are efficiency. Second, huge fluctuations among efficiency score have been observed and we showed that the pure technical efficiency (rather than scale efficiency) mainly caused these fluctuations. Third, we showed that 11 brands are operating under constant return to scale while the remaining 39 brands are under decreasing return to scale. It means that these 39 brands need to reduce initial investment amounts and improve management efficiency to increase their efficiency scores, rather than expansion which is more likely to result in efficiency score drop. 본 연구는 100개 이상의 가맹점을 가진 50개 교육 프랜차이즈 브랜드들의 효율성을 가맹 점주 관점(초기 투자 비용 대비 단기적 및 장기적 효율성)에서 DEA 모형을 이용하여 분석한 결과 다음과 같은 결과를 도출하였다. 첫째, CCR 모델 기준으로 효율적인 브랜드는 총 8개(대성독서논술리딩게임, 매쓰캔, 빨간펜수학의달인, 셀파우등생교실, 셀파중등논술, 장원교육, 제3교실, 한솔독서논술교실)이며 BCC 모델 기준으로 효율적인 브랜드는 상기 8개 브랜드에 11개 브랜드(YBM리딩클럽, 비상 IVITZ, 삼성영어, 셀파수학교실, 와이즈만영재교육, 윤선생영어교실, 한솔플러스수학교실, 한우리독서토론논술, 해법공부방, 해법독서논술교실, 해법영어교실)가 추가된 총 19개 브랜드임을 확인하였다. 둘째, 교육 프랜차이즈 브랜드의 효율성이 브랜드 간 큰 편차를 나타냈으며 비효율의 주 원인이 규모의 비효율보다는 순수 기술 비효율인 경우가 더 많음을 확인하였다. 셋째, 규모의 경제를 분석한 결과 최적 규모에서 운영중인 브랜드는 11개이며 나머지 39개 브랜드는 규모 수익 감소 상태임을 확인하였다. 이는 규모 수익 감소 상태에 있는 이들 교육 프랜차이즈 브랜드들이 초기 투자 비용의 상승을 통한 외형 확대시 일반적으로 효율성이 더 낮아지므로 초기 투자 비용의 감소 및 경영 효율화를 지향해야 비효율적 브랜드에서 효율적인 브랜드로 변화할 수 있음을 의미한다.

종합병원 간호사의 셀프리더십과 직무몰입이 임상수행능력에 미치는 영향
한용희,박영례 한국간호과학회 간호행정학회 2013 간호행정학회지 Vol.19 No.4
Purpose: This study was a retrospective survey to examine economic feasibility of home care services for patients with diabetic foot. Methods: The participants were 33 patients in the home care services (HC) group and 27 in the non-home care services (non-HC) group, all of whom were discharged early after inpatient treatment. Data were collected from medical records. Direct medical costs were calculated using medical fee payment data. Cost-effectiveness ratio was calculated using direct medical costs paid by the patient and the insurer until complete cure of the diabetic foot. Effectiveness was the time required for a complete cure. Direct medical costs included fees for hospitalization, emergency care, home care, ambulatory fees, and hospitalization or ambulatory fees at other medical institutions. Results: Mean for direct medical costs was 11,118,773 won per person in the HC group, and 16,005,883 won in the non-HC group. The difference between the groups was statistically significant (p=.042). Analysis of the results for cost-effectiveness ratio showed 91,891 won per day in the HC patients, and 109,629 won per day in the non-HC patients. Conclusion: Result shows that the cost-effectiveness ratio is lower HC patients than non-HC patients, that indicates home care services are economically feasible.

美國에 있어서의 Populism에 관한 硏究 : 革新主義와 關聯하여
韓庸熙 淑明女子大學校 1975 論文集 Vol.15 No.-
Populism in America is a precursory movement of Progressivism which is, as C.M. Merriam said, a liberal and progressive theory of stronger government under more democratic control with a broader social program. Therefore progressivism is distinguished from the mere liberal reformation movement. Progressivism at the end of 19th century is, so to speak, meant to attempt to purity politics and regulate popular-politics. Populism was not merely a peasant-movement of western frontier but a great movement of American farmers including South, and it was a spacious popular-movement to head for the cooperation with urban laborers as well as negros. Populism made a start with the organization of the People's Party at St. Louis in Feb. 1892. The occurrence of populism was caused by the Economic Revolution especially by rapid agricultural revolution which brought about the over production of agricultural products and depreciation in price. The reformation movement of American peasants and laborers caused Granger Movement, Anti Monopoly Party, Reform Party and Independent Party to be appeared. It was extended to the culmination by Green Party and Labour Reform Party. The characteristic of populism were shown distinctly through the programs of the farmer's alliance in 1880's and Populist Party organized in 1892. The Ideology of Populist Party, as Hofstadter said, was stimulated by corruption and degradation of political party, poverty of farmers, the conflict between labour and capital during the great depression in 1870's, and the wide spread of social discomposure. Populist party declined with the problem of Free Silver, and came to an end to join with the Democratic Party at the presidential election in 1896.

뇌 대사물질 팬텀을 이용한 뇌의 자기공명 온도측정법에 관한 기초 연구
한용희,장무영,문치웅,Han, Yong-Hee,Jang, Moo-Young,Mun, Chi-Woong 대한의용생체공학회 2010 의공학회지 Vol.31 No.5
In this study, we measured the chemical shift change of metabolite peaks in the brain-metabolite phantom according to the temperature variation using nuclear magnetic resonance(NMR). The temperature range in NMR system was controled from 25 to 80 (5 step) by internal temperature controller. Temperature coefficients of each metabolite peaks were also calculated from the measured chemical shift depending on the temperature. The chemical shift changes depending on temperature were validated by linear regression method for each metabolite peaks. The temperature coefficients of $_{tot}Cr$, Cho, Cr, NAA, and Lac were 0.0086, 0.0088, 0.0091, 0.0089, and 0.0088ppm/$^{\circ}C$, respectively. This study shows that chemical shift change of brain metabolite and temperature variation have linear relationship each other. This also makes authors believe that brain temperature measurement is possible using MR spectroscopic imaging technique.
