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.

This paper examines the applicability of formal safety assessment to the passenger ships. This is followed by an analysis of passenger ship characteristics and a proposed formal safety assessment methodology. Five interlocking steps are described to construct a safety model including novel risk assessment, cost-benefit analysis and decision-making approaches. A case study is carried out in order to demonstrate the proposed methodology. Further development in formal safety assessment in the context of passenger ship safety is finally discussed in detail.

There has not been any scientific analysis on appropriate size of workforce and salary for civilian workers in military so far. Thus, this paper conducted analysis on propriety in employment size of military doctrine researchers using system dynamic methodology based on annual military doctrine workload. Vensim software was mainly used to measure complement of the research group based on data from job analysis. Secondly, a multiple regression analysis was performed to study an appropriate wage for researchers based on their expertise and working condition. The data from twenty public research institutions and twenty eight job positions that are performing similar duty with military doctrine researchers was obtained and utilized to create a salary-estimation regression equation in the analysis. Finally, with cost-benefit analysis method this paper studied financial effectiveness of hiring military doctrine researchers. Contingent valuation method, which has been recognized as one of the most effective methodologies in cost-benefit analysis on intangible value, was utilized to measure benefit of hiring the researchers. The methodology presented in this paper can be applied to measure and improve the efficiency of military organization not only in military doctrine research area but also in several military functional area (military training, logistics, administration, combat development, and combat support).

본 연구에서는 중국 고등학생의 고등교육의 수익에 대한 기대를 탐색적으로 분석하였다. 고등교육수익은 금전적 투자적 수익, 비금전적 투자적 수익, 소비적 수익으로 구분하였고, 학생개인변인 및 가정배경변인에 따른 기대 차이도 분석하였다. 본 연구는 중국 산동성 연태시의 2개 고등학교에서 각각 300명 학생과 그들 학부모 300명, 총 1,200명을 대상으로 설문 조사하였다. 수집된 자료는 SPSS를 활용하여 교차분석, 일원분산분석 등을 통해 집단 간, 항목 간 차이를 검증하였다. 주요 결과는 다음과 같다. 첫째, 중국 고등학생들은 전반적으로 고등교육의 수익에 대한 기대가 높았다. 둘째, 성별, 학년, 성적 등 학생개인변인에 따라 고등교육수익에 대한 기대에 차이가 있다. 셋째, 가정배경변인에 따라 고등교육수익에 대한 기대에 차이가 있다. 넷째, 학부모와 학생 간에 고등교육수익에 대한 기대에 차이가 있다. 앞으로 고등교육정책이나 대학운영에서 이러한 다양한 기대와 차이를 고려해야 할 것이다.

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.

지형공간정보체계에 대한 투자의 타당성을 조사하는 방법으로 비용효과분석을 하는 경우가 많다. 경제학분야의 비용/효과 분석기법을 일반적인 정보체계도입의 타당성조사에 대해서 많이 활용하여 왔으며 최근 GSIS에 대해서도 적용시키려는 노력이 많이 진행되고 있다. 본 연구에서는 국내 GSIS에 적합한 비용/효과 모델을 확립시키고 이모델을 시설물관리 업무에 적용시켰다. GSIS의 구축에 필요한 비용의 항목을 결정하고 각각의 항목에 필요한 단가를 조사하여 결정하므로서 국내실정에 맞는 비용모형을 제시하였으며 효과모형의 확립에서는 지형공간정보체계를 도입하므로서 얻을 수 있는 효과를 특성에 따라 분류하였으며 분류된 항목 중 정량화 가능한 항목을 세부적으로 분류하였다. 확립된 비용/효과 모형을 국내의 대규모의 도시가스공금 업체에 적용시켜 100명 이상의 직원수와 300,000 가구이상의 수용가를 관리하는데 필요한 GSIS를 설계하였으며 이러한 GSIS를 구축할 때의 비용과 GSIS의 도입 없이 수동식으로 운영하는 비용을 계산하여 비교하였다.

Objectives: This study aims to evaluate the economic efficiency of a nutrition management program for children under 5 years of age in Kenge, Kwango District, Democratic Republic of the Congo (DR Congo) from 2014 to 2016. Methods: The economic efficiency of a nutrition management program for children under 5 years of age who have recovered from malnutrition status was evaluated using a cost-benefit analysis. The costs were analyzed according to the executed budget incurred during the project period. The benefits were estimated as the monetary value of the saved lives of children under 5 years of age. The economic efficiency of the program was determined by the Benefit-Cost Ratio (BCR). The BCR was calculated by dividing the total discounted benefit by the total discounted costs. The project is economically efficient when the BCR is greater than 1. Results: The costs of the nutrition management program were calculated as 1,677,609,648 Korean Won (KRW). A total of 2,466 children survived with improved malnutrition status through this program. The benefit for the reduction of mortality for children under 5 years of age was estimated to be 6,814,354,467 KRW, the estimated value of life for 2,466 children. The BCR was 4.06. Conclusions: The nutrition management program for children under 5 years of age in DR Congo was found to be a cost-effective project. Successful and efficient Official Development Assistance (ODA) for a health project requires integrated and comprehensive strategies and specialized international development consulting to improve efficiency. Future nutrition management programs should take into account the national health program to maintain the sustainability of the project.

제조업을 중심으로 분석한 환경관련투자 효율성의 주요 연구 결과는 다음과 같다. 내부수익률과 편익의 현재가치를 가변비용절감부문, 투자비용절감부문, 임대수입부문으로 분해함으로써 기존 연구의 범위를 확장했다. 그리고 단기총비용과 임대수입의 역할을 탐구하여 편익의 현재가치는 편익의 크기만을 나타내는 반면, 내부수익률은 효율성의 존재여부를 나타냄을 발견했다. 그리고 내부수익률과 시장이자율을 비교하는 투자효율성 방법론으로 환경관련투자와 관련된 투자효율성과 편익을 분석함으로써 사후 비용편익분석을 수행했다. 그 결과 환경투자, 공해방지투자 모두 비효율적인데, 공해방지투자가 환경투자보다 더 비효율적임을 발견했다.

Objective: The purpose of this study is to propose the benefits of reduction measures according to the occupational radon reference level in order to present basic data for radon management guidelines considering domestic circumstances. Methods: This study uses radon data measured in the subway stations from 2015 to 2016. Of the total of 4,643 cases, 4,231 cases were analyzed excluding the 412 cases where the values were below $300Bq/m^3$. Results: Cost-Benefit analysis was done on the results of the field survey on subway work sites. At the exposure level of $400Bq/m^3$, the ratio between the cost and the benefit was highest at 1 : 1.81(the cost was KRW 1,398,568,032, while the benefit KRW 2,5248,772,841). At the exposure level of $600Bq/m^3$, the ratio of cost and benefit was 1: 1.80, at $300Bq/m^3$ it was 1.72, at $800Bq/m^3$ it was 1.71, at $200Bq/m^3$ it was 1.54, and at $100Bq/m^3$ it was 1.40. Conclusions: Radon management in the workplace provides economic benefits and appropriate reduction strategies are needed. In addition, it is necessary to establish and distribute radon exposure assessment procedures and guidelines for the safety and health of employees when exceeding the exposure standard, and guidelines for radon management in the workplace should be established.
