Purpose: Human Papillomavirus(HPV) vaccination is the best prevention for cervical cancer. Therefore, this study was to examine the best predictors of HPV vaccination status in female nursing university students. Methods: Five hundred and forty junior and senior female nursing students from Seoul and provinces of Kyunggi, Chungcheong and Gyungsang completed paper and pencil questionnaires. Descriptive statistics, $x^2$ test, t-test, and multiple logistic regression with dummy variables were conducted using SAS 9.2. Results: Of the total students, 56.8% were vaccinated. As a result of the analysis of the bivariate relationships, family economic status, school type, perceived susceptibility, perceived benefit and perceived barriers (cost, time, distance from hospital and side effects) were significantly related to vaccination status. After controlling for the general characteristics and the HPV related knowledge score, higher family economic status (Adjusted Odds Ratio [AOR]: 3.78, 95% Confidence Interval [CI]: 1.21~11.76), private university (AOR: 1.69, 95% CI: 1.14~2.53), higher perceived benefit (AOR: 1.80, 95% CI: 1.47~2.20), lower perceived barrier (cost) (AOR: 0.86, 95% CI: 0.74~0.99), lower perceived barrier (time) (AOR: 0.71, 95% CI: 0.61~0.84), and lower perceived barrier (side effects) (AOR: 0.82, 95% CI: 0.72~0.94) were significantly related to HPV vaccination. Perceived benefit, perceived barrier (time) and perceived barrier (side effects) were the top 3 predictors of HPV vaccination status. Conclusion: This study suggests that vaccinated female nursing students were more likely to be from higher family economic status and private universities and have a higher perception of benefit and a lower perception of barriers (cost, time, and side effects). Thus, efforts to increase HPV vaccination rates of female nursing students should focus on improving their perception of benefit while lowering their perception of barriers, particularly cost, time and side effects.

Attention on daylighting should be focused not so much on a simple maximization of the natural light available in a space, as on improving the quality of lighting by ensuring as even but intense distribution of illumination in inner areas. An architectural means of optimal daylight distribution is by using so-called light shelf systems, horizontal shading and redirecting devices. The overall performance of the daylighting system can be improved by the incorporation with electric lighting control devices. This paper aims to exemplify the benefit of daylighting in term of economic consideration. In such a case a reasonable technique to compare system costs is by life-cycle costing. Stated simply, a life-cycle cost represents the total cost of a system over its entire life cycle, that is, the sum of first cost and all future costs. Four different electric lighting system designs are proposed and a lighting control system that is continuously operating according to the level of daylight in the space has been adapted. The result shows clearly that although denser layout of lighting fixtures might be more effective to interface to the level of daylight ceaselessly changeable, its economic benefit may not meet the expected criterion the reason of increased initial investment and maintenance cost for the fixtures and control devices.

Crop yield insurance program in Korea has rapidly grown not only in quantity but in quality for 15 years since it was introduced in 2001. Despite growth of Crop insurance, performance evaluation for crop yield insurance has not fully been evaluated at the farm, consumer and national level. The purpose of this study is to conduct the performance evaluation for crop yield insurance through estimating the effects of farm revenue stabilization and social welfare increase with three popular insurance items: apple, pear and sweet persimmon. Based on the analysis of social welfare effect, cost-benefit analysis of operating crop yield insurance was conducted at the national level. We found that crop yield insurance stabilizes farm revenue based on the estimated four risk indicators: Coefficient of Variation, Value at Risk, Certainty Equivalence, and Risk Premium. The result of cost-benefit analysis shows that crop yield insurance increases social net benefit by 44.1 billion won for the three items. As a result, crop yield insurance program has contributed remarkably on social welfare as well as farm management and its role will be more important in the future.

정보화사업의 편익을 평가할 때 학계에서는 많은 경우 현금흐름이 분명한 직접적 편익만을 고려했다. 본 연구는 한국형 공간정보시스템 도입을 사례로 하여 학계가 그동안 소홀히 한 간접적 편익을 추정한다. 한국형 공간정보시스템은 외국산 소프트웨어에 의존하던 기존의 시스템을 국산 소프트웨어로 대체하고, 클라우드 시스템을 도입하는 것이다. 이에 따른 간접적 편익으로는 선택가치, 국가 브랜드 강화, 대민 서비스 품질 향상, 국내 경쟁력 향상 등을 들 수 있다. 이러한 편익은 시장에서 거래되지 않기 때문에, 본 연구에서는 조건부가치추정법으로 추정했다. 본 연구에 따르면 한국형 공간정보시스템의 간접적 편익이 적지 않은 것으로 나타났다. 간접적 편익을 실제로 비용편익분석의 편익항목으로 포함시킬 것인지는 학계에서 더 논의할 필요가 있다. 실제로 외국의 경우, 간접적 편익 가운데 일부는 비용편익분석의 편익으로 인정하는 것을 권하고 있다. 본 연구는 앞으로 그러한 논의의 토대가 될 수 있을 것으로 보인다.

본 논문에서는 정량적 위험성 평가 결과 위험경감조치로 제시한 ILI (In-line inspection, 배관내부검사)가 합리적으로 이행가능한지를 판정하기 위해 비용-편익 분석을 실시하였으며, 비용-편익 분석을 통해 ILI의 합리적인 이행시기를 결정하였다. 본 논문에서 편익의 산정은 인간의 생명 가치를 측정하는 VPF (Value of Preventing a Fatality; 사망자를 막는 가치)를 이용하였으며, 국내의 도시가스 고압배관의 위험경감조치에 대한 비용-편익 분석에 적정한 VPF 값은 20억원으로 하였다. 두 개의 사례연구 결과 위험경감조치로 제시된 ILI의 이행시기는 13년을 주기로 2회 (13년 및 25년) 또는 15년이 되는 해 1회 실시하는 것이 가장 합리적임을 알 수 있었다.

재해위험지구 정비사업의 질적 수준제고를 위하여 재해위험지구 정비 사업을 대상으로 비용 대비 편익을 분석하였다. 최근의 재해이력을 고려하여 8개의 분석대상 지구를 선정하였고, 비용편익비(B/C)를 사용하여 투자효과를 분석하였다. 편익 산정은 해당지역의 과거재해이력을 활용하였으며, 비용은 총사업비로 평가하였다. 8개의 분석대상 지구에 대한 분석결과는 영향범위, 할인율 등의 인자에 따라 다른 범위에서 1보다 큰 B/C를 보여주고 있다. 분석결과에 따르면, 4% 할인율과 5 km 영향거리 조건에서 8개 대상 지구에 대한 평균 B/C는 4.1로 1이상을 나타내는 것으로 확인되었다. 이러한 결과로 볼 때 재해위험지구 정비 사업은 비용 대비 효율이 높을 것으로 판단된다.

The purposes of this study are to assess pig farmers' preference for highly pathogenic porcine reproductive and respiratory syndrome (PRRS) vaccine, and estimate the cost and benefit of PRRS vaccination in Vietnam. This study employed an integrated epidemiological and economic analysis which combined susceptible-infectious-recovered (SIR) model, choice experiment (CE) and cost-benefit analysis (CBA) together. The result of SIR model showed the basic reproduction number ($R_0$) of PRRS transmission in this study is 1.3, consequently, the optimal vaccination percentage is 26%. The results of CE in this study indicate that Vietnam pig farmers are showing a high preference for the PRRS vaccine. However, their mean willingness to pay is lower than the potential cost of PRRS vaccine. It can be considered to be one of the reasons that the PRRS vaccination ratio is still low in Vietnam. The results of CBA specified from the whole society's point of view (Social perspective), the benefits of PRRS vaccination are 2.3 to 4.5 times larger than the costs. To support policy making for increasing the PRRS vaccination proportion, this study indicates two ways to increase the vaccination proportion: i) decrease vaccine price by providing a subsidy, ii) provide compensation of culling only for PRRS vaccinated pigs.

The volume of B2C products rapidly increases according to the activation of the electronic commerce. Small and medium electronic commerce companies request the establishment of Parcel Warehouse &Distribution Center(PWDC) that is invested by the post office. This paper presents an economic evaluation method for PWDC from the perspectives fo PWDC and the post office. Two types of warehouses are considered as alternatives for PWDC. One is the conventional warehouse, and the other is the automamic warehouse that is characterized by AS/RS and automatic dispenser system. A benefit/cost analysis method is used to evaluate PWDC since it has the property of public enterprise. A PWDC which will be located in Seoul and adjacent to a concentrated post office is selected as a case study to illustrate the procedure of economic analysis.

This study attempts to analysis of the 1'ole and B/C(Benefict/Cost)of National Supported Supercomputing Center in process of the promotion for informatization in Korea. ETRI Supercomputing Center, as National Supported Supercomputing Center, was established in 1967 as a laboratory of KIST(Korea Institute of Science and Technology). ETRI Supercomputer Center have acted a leading role as National HPCC(High Performance Computing and Communication) in Korea. The result of B/C analysis of En Supercomputer Center showed that it is twenty times benefit as many as cost for the last 30 years. As soon as possible, it was Suggested that ETRI Supercomputer Center must be developed as National Supercomputing Center(NSC).
