Environmental pressures from such sources an economic condition, the government and inter-institutional competition create managerial challenges. Economic pressures may be forcing dietetic dept, in hospital to utilize cost∙benefit analysis to assist them in their problem solving. Cost∙benefit analysis have been widely used in business, industry and many other fields with only limited application to foodservice. Due to the lack or this information the purposes of this study were to identify use of cost∙benefit analysis in hospital foodservice system to evaluate the economic efficiency of alternatives, and to make recommendation for operation system change. Using the cost∙benefit method, cash flows are separated into cost and benefits. For an alternative to be selected, indicators, such as NPV, benefit-cost ratio (B/C ratio) with 5% discount rate per annum. The sensitivity analysis was also conducted with difference rate 3%, 7% respectively and reduced employee payroll change. The result of this study can be summarized as follows : 1. The total cost of investment for operation system change was 390,570 thousand won and the total benefit through operation system change was 865,808 thousand won. 2. Net present value(NPV) for 5 years was 475,239 thousand won and benefit-cost ratio was 2.22. 3. In sensitivity analysis with different discount rate 3%, 7%, benefit-cost ratio was 2.25, 2.18 respectively, with total reduced employee payroll change, benefit-cost ratio was 2.86. In conclusion, total benefits were exceeded total costs. Therefore, the project of operation system change in hospital foodservice was found to be economically efficient.

고용노동부 "고용보험DB" 의 상실자 종합통계와 실업급여 지급통계를 이용하여 구직급여 수급자격자의 수급과 재취업에 따른 수급자격 상실을 경합적 위험(competing risks)모형으로 분석하였다. 아울러 구직급여 수급률과 경기지수 간의 교차상관관계 분석을 하였다. 분석결과 구직급여 수급률이 실업률과 정(+)의 상관관계를 보이고, 6개월가량 실업률과 경기동행지수를 선행한다. 아울러 수급률이 연령, 학력, 급여지급기간, 소득대체율과 정(+)의 상관관계를 보이고 있다.

Purposes: This study aims to analyze the correlation with the current status of the medical resident application rate, physician's income, and non-benefit rates of majors in each specialty subject and to suggest implications. Methodology: First, it analyzes the correlation between the medical resident application rate by specialty subject and the income of physicians. Second, it analyzes the correlation between the income of specialists and the non-benefit rate for each specialty subject at the clinic level. Findings: First, a significant positive correlation was found between the medical resident application rate and the average physician's income for each specialty subject (r=.718, p<.01). Second, a significant positive correlation was observed between physician income at the practitioner level by medical specialty and the non-benefit rate (r=.726, p<.01). Practical Implications: In this study, the correlation between medical resident application rate by specialty subject and physician's income, non-payment and physician's income was confirmed. Choosing a department that is less risky and can earn higher income is a natural phenomenon, but it is necessary to adjust the physicians crowding phenomenon to a specific specialty subject at the government level to maintain the medical system.

이 연구는 파각란 선별기 도입을 비용 편익분석 목적으로 수행되었다. 계란 파각란 선별기를 도입할 때의 총수입과 총비용 평가액의 추정결과는 다음과 같다. 총비용의 경우 구입가격, 고정비용 및 유동비용의 합계로 나타내었고, 할인율에 따라 5%, 10%일 때 각각 232,904천원과 242,904천원으로 산정되었다. 계란 파각란 선별기 평가액은 할인율에 따라 228,543천원(할인율 5%인 경우)과 218,543천원(할인율 10%인 경우)으로 추정되었다(Table 6). 파각란 선별기 기술가치에 대한 평가는 B/C비율, 순현재가치(NPV), 내부수익율(IRR)의 값으로 판단되었고, 내부수익율 IRR의 값은 가정했던 할인율보다 훨씬 높게 나타났고, 순현재가치도 0보다 큰 값으로 나타났으며, B/C비율도 1.0 이상으로 나타나 경제적 타당성을 가지는 것으로 판단되었다(Table 7).

Purpose: The objective of this study is to verify the economic validation of quality management integrated train freight car by analyzing economic evaluation indicators such as benefit and cost, net present value, and inter rate of return. Methods: First, we itemize benefit and cost field by reviewing literatures; Benefit consists of 1)Safety, 2)Operation, and 3)Maintenance; Cost consists of 1)Set-up fee, 2)Wireless internet fee, and 3)Cloud storage using fee. Second, based on these estimated values, we conduct an economic evaluation analysis. Among them, benefit and cost, net present value, and internal rate of return are selected. Results: As a result, all estimated values are highly over criterion of economic validity($$B/C{\geq}_-1$$, $$NPV{\geq}_-0$$, $$IRR{\geq}_-R$$); 1)benefit over cost ratio is 28.22, 2)Net present value is 8,121.66million KRW, and 3)Internal rate of return value is 2272%. Conclusion: The findings of this study will help making a decision when train industry adopts IoT technology for improving the effectiveness.

Fishing population has been increasing with national income improvement and the five-day workweek in Korea. Recently commercial fishing facilities like pay fishing pond are emerging as demand of saltwater fishing increases, unlike the past when inland fishing was prominent. In order to do businesses, economic analysis should be done in advance. This study aimed to make an Economic analysis of Uljin pay-fishing place by estimating the cost and benefit, and calculating the rate of economic return. The results show the Uljin pay-fishing place's net present value of 3.5 billion won, internal rate of return of 14%, and benefit cost ratio of 1.16 at 5.5% social discount rate.

Objectives: Since 1991, nationwide massive neonatal screening program for phenylketonuria (PKU) and congenital hypothyroidism have been performed in Korea. As in many other countries, efficiency of this program has not been definitely concluded. For the purpose of evaluation of this program, from the perspective of efficiency, a cost-benefit analysis was carried out. Methods: Costs of the detection and the treatment program were compared with the projected benefit(avoided costs) that results from the prevention of the mental retardation associated with the disorders due to PKU and hypothyroidism. Costs and benefits were discounted at an annual rate of 5%, and duration of life-long labor was assumed to be 30 years. Cost and benefit were estimated based on the detection rates of one case of PKU per 5,572 and one case of congenital hypothyroidism per 32,554 babies screened during 1991-1997. Results: The benefit-cost ratio was 0.418. The sensitivity analysis for the discount rates and labor durations showed that most cost-benefit ratios were lower than one(1.0) except when discount rate was changed to 3% and detection rate to two- or threefold and/or labor duration to 40 years. Conclusion: The result of this study suggested that present program of mass screening for PKU and congenital hypothyroidism could not be justified in terms of efficiency. It doesn't coincide with the results of previous studies in major developed countries, presumably because of difference in detection rates and welfare cost for the disabled.

본 논문에서는 현실적으로 실업보험급여가 수급기간별로 차등지급되기 어렵다는 전제하에 가장 바람직한 실업급여체계가 어떠한 것인가를 분석하고 있다. 특히 법정수급기간과 소득대체율이 실업자들의 구직유인과 소득안정에 대해 미치는 영향을 파악하고, 이에 따라 사회후생을 극대화시킬 수 있는 법정 수급기간 및 소득대체율의 조합을 분석하고 있다. 아울러 본 모형을 통해 적정 실업급여체계를 결정하는 여러 가지 요인들을 도출하고, 그에 의거하여 앞으로 우리나라의 고용보험제도의 개혁 방향을 제시하고 있다.

계란 세척기 평가 금액 추정 결과는 다음과 같다. 계란 세척기 총수입(인건비 절감으로부터의 조수입 증대)에서 산정하였으며, 계란 세척기 총비용은 구입가격, 고정비용 및 유동비용의 합계로 나타내었다. 계란 세척기 평가액은 할인율 수준에 따라 최소 44,778천원(할인율 10%)에서 최대 45,778천원(할인율 5%), 평균 45,278천원으로 추정된다(Table 7). 계란세척기의 경제적 타당성을 살펴보면, 내부수익율 IRR의 값은 가정했던 할인율(5%~10%)보다 훨씬 높고, 순현재가치(NPV)는 0보다 훨씬 크며, B/C 비율도 1.0 이상으로 나타나 계란 세척기 개발사업의 경제적 타당성은 있는 것으로 판단된다(Table 8).
