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.

Objectives: The study was conducted to evaluate the effects of the students majoring in dental hygiene on their oral health beliefs and oral health behavior. Methods: The survey was conducted using selfadministered questionnaires targeting 619 female students majoring in dental hygiene at three Universities in k and J province. The stronger health oral belief means higher score in susceptibility, severity, benefit and salience, but the higher score in barrier means stronger recognition in obstacle. Results: There was significant correlation between susceptibility and experience of not-treated oral disease (OR [odds ratio] 2.40; 95% CI [confidence interval] 1.73-3.34)' and 'dental caries (OR 2.36; 95% CI 1.25-4.45)'. Benefit had significant correlation with 'visiting dental clinic (OR 1.58; 95% CI 1.14-2.19)'. Salience had significant correlation with 'experience of not-treated oral disease (OR 0.70; 95% CI 0.52-0.94)'. Barrier had significant correlation with 'visiting dental clinic (OR 0.73; 95% CI 0.56-0.95)' and 'removing oral plaque (OR 0.71; 95% CI 0.52-0.95)'. There was no significant correlation between oral health belief and 'using of oral hygiene device' or 'regular tooth brushing'. Conclusions: Diverse oral health behaviors were affected by susceptibility, benefit, salience and barrier in oral health belief. The programs for oral health education and preventing oral disease should be prepared to change oral health belief to promote the oral health systematically based on the results of this study.

This research carried out an analysis on input cost and leakage reduction effect by leakage reduction method, focusing on the project for establishing an optimal water pipe network management system in the Taebaek region, which has been executed annually since 2009. Based on the result, optimal cost-benefit analysis models for water distribution network rehabilitation project were developed using DEA(data envelopment analysis) and multiple regression analysis, which have been widely utilized for efficiency analysis in public and other projects. DEA and multiple regression analysis were carried out by applying 4 analytical methods involving different ratios and costs. The result showed that the models involving the analytical methods 2 and 4 were of low significance (which therefore were excluded), and only the models involving the analytical methods 1 and 3 were suitable. From the result it was judged that the leakage management method to be executed with the highest priority for the improvement of revenue water ratio was installation of pressure reduction valve, followed by replacement of water distribution pipe, replacement of water supply pipe, and then leakage detection and repair; and that the execution of leakage management methods in this order would be most economical. In addition, replacement of water meter was also shown to be necessary in case there were a large number of defective water meters.

The most representative fruit in Yanbian area is Applepear(Ping Guo Li). It has been a important resource of farm income. According to the economic growth and income Increase of individual consumers, food consumption pattern will be changed from grain to high value cash crops such as Applepear and vegetables. The globalization and adapt ion of free market oriented economic policy of China government have led to change the collective farming system to individual farm management system. The institutional transformation have brought about high productivity of farm products and incomes of farmers. Therefore the plantation area of Applepear and requirement of investment cost for establishment of Applepear farms have increased rapidly since the 1980's, the time of perestroika and glasnost in Chinese economy. In prosperity of Chinese agriculture, individual farmer's decision making as free selection of farmland use, selection of high pay-off crops, free sale of the products in free market and credit support for the project might be the most important factors. In case of Applepear farm development, net present value of the project net benefit was estimated at 55.518won per hectare and financial rate of return was 21%. The benefit/cost ratio of the project was 2.11. Considering 10% of discounting rate or the opportunity cost of capital in China the Applepear farm development project showed us economically feasible in the light of the above efficiency indices. The Chinese government has to support Applepear farm development project financially and institutionally considering the high-payoff benefit of the fruit and farmer's in come increase in the future.

Purpose: This study conducted an economic evaluation of hospital-based home care services for the patients who had undergone breast cancer surgery. Methods: A total of 12,483 patients over 18 years of age who had received breast cancer surgery in 26 tertiary hospitals in 2018 were analyzed with the claim data from the Health Insurance Review & Assessment Service using cost-minimization analysis and societal perspectives. Results: There were 156 patients who utilized hospital-based home care services within 30 days after breast cancer surgery, and they received 2.17 (SD=1.17) hospital-based home care service on average. The average total cost was 5,250,028 KRW (SD=1,905,428) for the group receiving continuous hospital-based home care and 6,113,402 KRW (SD=2,033,739) for the group not receiving continuous hospital-based home care (p<.001). The results of the economic evaluation of continuous hospital-based home care services in patients who had undergone breast cancer surgery indicated a total benefit of 953,691,000 KRW, a total cost of 819,004,000 KRW, and a benefit-cost ratio of 1.16 in 2018. Conclusion: Continuous hospital-based home care was considered economically feasible as the total costs for the group receiving continuous hospital-based home care were lower than those of the group not receiving continuous hospital-based home care. Therefore, policy modification and financial incentives are recommended to increase the utilization of hospital-based home care services for patients who had undergone breast cancer surgery.
