Objectives : This study has analyzed the relationship between DEA efficiency of costs-patient revenues, productivity per value added and management performance in mental hospitals. Methods : The relationship between DEA efficiency of costs-patient revenues, the productivity per value added and management performance were conducted with correlation analysis and logistic regression. Results : The DEA efficiency of costs-patient revenues had a significant causal relationship with the value added ratio to gross revenue indexing productivity per value added. On the other hand, it was revealed that the operating margin indexing management performance had a slightly significant causal relation with DEA efficiency of costs-patient revenues. Conclusions : The material costs should be focused on the management stability of mental hospitals, and known to the desirable management orientation for the higher efficiency of costs-patient revenues.

The purpose of this study was to estimate the socioeconomic costs resulting from alcohol drinking among adolescents as of 2006 from a societal perspective. Methods: The costs were classified into direct costs, indirect costs, and other costs. The direct costs consisted of direct medical costs and direct non-medical costs. The indirect costs were computed by future income losses from premature death, productivity losses from using medical services and reduction of productivity from drinking and hangover. The other costs consisted of property damage, public administrative expenses, and traffic accident compensation. Results: The socioeconomic costs of alcohol drinking among adolescents as of 2006 were estimated to be 387.5 billion won (0.05% of GDP). In the case of the former, the amount included 48.25% for reduction of productivity from drinking and hangover, 39.38% for future income losses from premature death, and 6.71% for hangover costs. Conclusions: The results showed that the socioeconomic costs of alcohol drinking among adolescents in Korea were a serious as compared with that of the United States. Therefore, the active interventions such as a surveillance system and a prevention program to control adolescents drinking by government and preventive medicine specialist are needed.

본 연구는 관절병증질환자의 의료이용에 따른 의료비와 생산성손실비용 조사하고자 하였다. 본 연구를 위하여 2012년 한국의료패널 총 5,434가구, 15,872명을 이용하여 만19세 이상 관절병증질환자는 1,370명을 대상으로 하였다. 연구방법은 응급의료이용, 입원의료이용, 외래의료이용에 대한 평균의료이용횟수와 의료비를 구하였고, 연간관절병증 질환자의 응급생산성손실비용은 2012년 1일 평균임금 ${\times}$ N ${\times}$ 평균의료비를 곱하여 산출하였다. 연간응급 의료이용횟수는 1회, 의료비는 42,128,870원, 생산성손실비용은 98,640,000원이였다. 연간입원의료이용횟수는 4.79회, 의료비는 42,128,870원, 생산성손실비용은 945,036,820원이였다. 연간외래의료이용횟수는 12.7회, 의료비는 42,128,870원, 생산성손실비용은 91,252,728,000원이였다. 이상과 같은 결과를 바탕으로 다음과 같은 결론을 얻었다. 관절병증의 발생은 의료비증가와 생산성저하에 영향을 미칠 수 있으며 가구 및 환자에 있어 큰 부담이며 삶의 질도 저하될 것이다, 관절병증질환의 감소를 위한 운동 및 관리에 철저한 검토가 필요하다.

서울의 대중교통체계 개편에 따른 시내버스업체의 생산성 변화를 사고비용 고려여부에 따라 비교분석하였다. 사고비용과 같은 유해한 산출물을 고려하면서 공공기관의 생산성 분석에 적합한 자료포락분석기법의 방향거리함수를 사용하였으며, 그 값을 맘퀴스트 루엔버거 생산성 지수에 적용하였다. 시내버스업체는 운전, 정비, 관리, 차량, 연료의 투입물을 사용하여, 운행거리, 승객수 및 사고비용을 생산하는 기업형태로 상정하였다. 분석결과 사고비용 고려여부와 상관없이 생산성은 약간 증가한 것으로 나타났으며, 사고비용을 고려했을 때가 제외했을 때보다 약간 더 증가한 것으로 나타났다. 이는 시간의 흐름에 따라 운행거리와 승객 수에 대한 투입물의 사용이 줄어들었을 뿐만 아니라 그 이상으로 안전성과 관련한 서비스가 향상되었음을 의미한다. 또한 개편 분야별 생산성 변화에 미친 영향을 분석해본 결과, 운행속도 증가와 승객 수 증가가 생산성 증가에 가장 영향을 미친 것으로 나타났다. 이는 중앙버스전용차로 설치와 대중교통통합요금거리비례제 도입의 결과를 반영하는 것으로 이들이 시간의 흐름에 따라 투입물을 감소시키면서 사고비용을 줄이는데 효과적이었다고 볼 수 있다. 다만 준공영제를 포함한 운영체계의 개편은 생산성 증가와는 관련은 있었으나 큰 영향을 미치지는 못하였다.

Objectives: We wanted to estimate the annual socioeconomic costs of alcohol drinking in Korea. Methods: The costs were classified as direct costs, indirect costs and the other costs. The direct costs consisted of direct medical costs, indirect medical costs and subsidiary medical costs. Particularly, the medical costs and population attributable fraction for disease were considered to reflect the calculation of the direct medical costs. The indirect costs were computed by the extent to which the loss of productivity and loss of the workforce might have occurred due to changes in mortality and morbidity according to alcohol drinking. The other costs consisted of property loss, administration costs and costs of alcoholic beverage. Results: The annual costs, which seemed to be attributable to alcohol drinking, were estimated to be 149,352 hundred million won (2.86% of GDP). In case of the latter, the amount includes 9,091 hundred million won for direct costs (6.09%), 62,845 hundred million won for the reduction and loss of productivity (42.08%), 44,691 hundred million won for loss of the workforce (29.92%), and the other costs (21.91%). Conclusions: Our study confirms that compared with the cases of Japan (1.9% of GNP) and the other advanced countries (1.00-1.42% of GDP), alcohol drinking incurs substantial socioeconomic costs to the Korean society. Therefore, this study provides strong support for government interventions to control alcohol drinking in Korea.

The objectives of this study were to analyze the factors that affect the productivity for university food services. In a survey involving four-year university dining centers throughout the country, and correlations among thriteen different variables that affect productivity were determined. Productivity index (PI) was determined by meals per hour, the average score for 38 institutions was found to be 14.2 meals/hour. For serving methods, the fixed ration had a higher PI than the self-serving. When two types of serving trays were considered, the PI of the compartmantalized trays was higher than that of the tray accompanying saparate small dishes. When single (S)-or. multiple(M)-menu was compared with the cafeteria style, a higher PI was obtained by the S-or M-menu. Among the three operation systems, the PI was found to be the highest by direct operation (17.6 meals/hour), followed by contract operation (11.1 meals/hour) and rent operation (7.9 meals/hour). For the factors that affect the productivity of the university food services, the total number sewed (r=0.54, p＜0.001) and the use of convenient food items (r=0.28, P＜0.05) exhibited positive correlations, while food costs and labor costs showed negative correlations. This suggests that the productivity of university food service increases as the total number served and the use of convenient food item increased, but decreases as the food costs and labor costs per meal increased. A regression analysis showed that three variables - total number sewed, labor cost per meal, number of employees-influenced about 73% components of food service showed a negative correlation with PI and a positive correlation with the labor cost per meal.

본 연구는 한국노동연구원의 사업체패널조사 1-5차년도 자료와 행정자료인 "고용보험 DB"를 결합하여 구축한 "사업체-근로자 연계자료"를 활용하여 사업체 근로자의 연령구성과 생산성 및 인건비와의 관계를 실증분석 하였다. 사업체의 생산성은 1인당 부가가치로, 인건비는 1인당 노동비용으로, 사업체 근로자의 고령화 정도는 근로자의 연령구성으로 측정하였으며 동적패널모형을 활용하였다. 분석 결과, 생산성과 인건비 모두 사업체의 35-39세 연령대 근로자의 비율을 중심으로 역U자의 모습을 보였다. 즉, 35-39세 연령대 근로자 대신 더 젊은층의 근로자 혹은 더 고령층의 근로자 비중이 증가하는 경우 생산성 및 인건비에 부(-)의 영향을 미치는 것으로 나타났다. 특히, 35-39세 연령대 근로자 대신 50세 이상 연령대 근로자가 증가할 때의 생산성 추정계수와 인건비 추정계수와의 차이가 30세 미만 연령대 근로자가 증가할 때의 생산성 및 인건비의 추정계수와의 차이보다 더 큰 것으로 나타났다. 이러한 분석 결과를 통해 고령근로자의 생산성 저하에 대한 기업의 우려는 타당하나, 동시에 기업은 이미 인건비 조정 등의 방법을 통해 고령근로자를 효율적으로 활용해 왔음도 확인할 수 있다.

In general one can find an enormous number of studies about the productivity of land, labor and capital, very little has been done so far to communicate about the productivity of corporate information creating and information-consuming resources in ways that are useful to business executives. In view of the enormous share of corporate spending on information resources it would be useful in planning, budgeting, as well as in performance evaluation to measure how information resources are used in creating EVA(economic value-added). The effectiveness in deploying information resources has potentially a greater effect on corporate financial performance than any other economic influence. That in because corporate executives have greater discretion in directing what their information management staffs will do than in setting the terms for materials purchases, employee compensation, taxes or interest rates. The expenses for information are mostly in the form of overhead costs. Because expenses for information are mostly overhead costs and not for costs of goods, the prudent decision-maker should have a wide array of discretionary options available for allocating this resource. This study is intended for analysis the factors that having effects on the enterprise information productivity and is to description the factor using a foreign enterprise case study.
