This study tests the effectiveness of residents' direct evaluation method about the feasibility of cost of public facilities based on their willingness to pay. The main findings are follows. First, residents do not use the public facilities(Cultural Center and Library) frequently. The main reasons are the shortage of complemental supplies, low accessibility, and poor communication to public. Second, the Contingent Valuation Method(CVM) reveals the residents' unwillingness to pay for facilities by agreeing only 46.8% on the cultural center. Third, this study concludes that the CVM is an effective method to measure willingness to pay for public facilities and also an useful tool to aid priority setting in urban planning.

Rural Development Administration (RDA) has developed a manufacturing technology which can increase the amount of platycodin D in Platycodon grandiflorum. A study is needed to estimate the value of this new technology and predict the market demand for a new product. This study estimates additional amount of willingness to pay (WTP) using contingent valuation method (CVM) for a new product with the technology that RDA has developed. The survey was created under virtual health functional foods market of Platycodon grandiflorums. It was conducted with 1,000 adult males and females aged between 19 and 59 years old in 17 major cities and provinces nationwide from December 4 to December 7, 2018. The amount of WTP for the health functional Platycodon grandiflorum was drawn using maxinum likelihood estimation method. The estimated average and median WTP values are 21,933.85 won per person and 10,000 won per person, respectively. The independent factors, including the ratio of monthly average health function food consumption to income, the average monthly income level of a household, and existence of family members or relatives engaged in food and nutrition-related professions in a household, have been shown to have a statistically significant influence on the WTP. This study presents the potential magnitude of health functional food market and the value of the new technology based on health functional food market.

Designing mobile Interfaces is fundamentally different from designing online interfaces. Not only are there differences in underlying technologies, but also in the way people use mobile Interfaces. If these differences are not taken into account in designing mobile interfaces, mobile services are likely to fail. If mobile services do not deliver what people want, these services will fail no matter how excellent the underlying technology is. The user interface design commonly used in mobile services is based on multi-layered approach, which is not very user-friendly. A well designed single layered user Interface will be more user friendly than the conventional one and it will be having edge over others. However, it is quite difficult to Provide a single layered user Interface in a small screen. This study aims at examining how design attributes of mobile interfaces affect customer preferences. In order to explore customer preferences to each design attribute of mobile interfaces, we measure and analyze customer's WTP (Willingness To Pay) toward their different interface designs. Ultimately, throughout the study, we try to answer how to design mobile interfaces in small screen of mobile devices. In addition, we propose an optimal design solution that customers likely prefer.

Philippine fisheries code of 1998 (Republic Act 8550), which is enacted to achieve food security by managing, conserving and protecting fishery resources, obliges local governments to designate no less than 15% of jurisdictional municipal water as fisheries resource protection zone. Accordingly, Marine Protected Areas (MPAs) are the most extensively established as fisheries management and conservation tool and over 1,500 MPAs are reported in the Philippines. But there has been debate on the pros and cons of implementing MPAs because of the positive and negative impacts on local communities and fishermen. A dichotomous-choice contingent-valuation survey was conducted in the two municipalities of Guimaras, Philippines to investigate public opinion in debates over MPAs and to estimate willingness to pay (WTP) for MPAs to protect and conserve marine habitats for fishery resources. For the benefits and costs of MPAs, 43.6% of respondents thought the costs would be larger than the benefit, but 91% respondents voted in favor of increasing MPAs for fisheries resources as a protective measure. Finally, the estimated Turnbull lower-bound mean WTP (36.75ha) was php 493.6(US$ 11.3) per household to establish the additional MPA (36.75ha) in their municipality waters.

Objectives: The economic evaluation of health promotion programs has increasingly become an imperative activity for securing public fund or budget. The purpose of this study is to conduct an economic evaluation for the healthy school canteen program using the contingent valuation method(CVM). Methods: To estimate the benefit from the healthy school canteen program, double-bounded dichotomous choice method as a sort of willingness to pay was employed. Four hundred parents who lived in Seoul and have students at middle or high schools, were administrated by semi-constructive questionnaire containing the necessary information for benefit estimation. Cost estimation of healthy school canteen program was made referring to three types of pilot programs. Finally, the benefit against the cost was worked out according to the three levels of estimated cost. Results: Cost estimate is 8,488 and 9,311 won depending on the two senarios about how to invest on the program, respectably. The results of benefit estimate shows that the average cost willingness to pay(WTP) for healthy school canteen program is 21,275 won(16,963-59,838 won, 95% CI) and total benefits turned out 14.7 billion won. According to the cost-benefit analysis, average benefit-cost ratio is from 2.3 to 3.6. Conclusions: Healthy school canteen program could be economically accepted, and government can take consideration of expanding beneficiaries of healthy school canteen program for health promotion.

The objective of this study is to estimate the economic value of official management and control for invasive insects and diseases in fruits. The direct and indirect effect of this control measure can be the changes in price of fruits and related goods, changes in export volume of domestic fruits, changes in total volume of fruit production, and reduce the risk in food safety. The contingent valuation method with the single-bounded dichotomous choice is employed to estimate each household's willingness-to-pay (WTP) to maintain official management and control measures. The total number of sample consists 2,050 respondents between the ages of 19-60 years, and the survey is conducted using Web-based survey. The estimated results for mean WTP is 5,443won per month per household. Therefore, the total economic value of official management and control on fruit in Korea is estimated to be approximately 94.4 billion won per month.

A marine protected area (MPA) is a spatially designated section of the ocean where the biodiversity is high. Munseom MPA has a unique underwater landscape including soft coral, subtropical fish, and benthos, attracting many scuba divers. This paper intends to evaluate the willingness-to-pay (WTP) for the scuba diving management policy in the Munseom MPA. As a stated preference valuation method, a choice experiment was applied to assess divers' preferences with economic values for the policy. The attributes used in the study included zoning (temporal closure), conservation education, daily permit, soft coral area, and diving fee. We collected 333 questionnaires through online and field surveys and used 296 after excluding incomplete responses for the final data analysis. Study results show that a six-month closure, a decrease in soft coral habitat, and the diving fee were statistically significant. A positive coefficient with regard to the six-month closure variable indicates that divers preferred the policy, and the marginal willingness to pay (MWTP) was estimated to be KRW 8,637 per person per dive. The aggregate WTP of KRW 233 million was obtained by multiplying the MWTP by the number of visiting divers per year. When comparing the levels of recreation specialization, more skilled divers preferred the management option. The results of this study will help predict the priority of management measures and the levels of acceptability among divers when diving management is implemented in Korea in the future. This study suggests that marine environmental policies need to consider divers as one of the important stakeholders for marine conservation.

The purpose of this study is to estimate the biodiversity conservation value of Heory stock in Sun-Cheon. Expected values of residents' Willingness To Pay (WTP) was estimated using Contingent Valuation Method (CVM) which is the most popular method in estimating conservation values of biological diversities. Three different estimation methods were used in statistical estimation, and the results were different from each other. Results of statistical analysis show that the expected value of WTP in logit model is highest, 5,772 Won per month. Those of A model which conducted OLS estimation using open ended questionnaire and B-1 model which conducted OLS estimation using dichotomous choice questionnaire were 1,978 Won per month and 2,391 Won per month respectively. The average expected value of WTP from three model was 3,380. This average value was expected to reduce methodological biases.

While the expansion of protected areas in accordance with Korea's National Biodiversity Strategy contributions to the conservation of biological diversity, it incurs economic losses and poses threats to the livelihoods of local residents. Payment for ecosystem services (PES) compensates local residents for their economic damages in a sustainable manner. To assess feasibility of PES, there is a need to estimate the general public's benefits from biodiversity conservation in protected areas. This study attempted to estimate visitors' willingness to pay (WTP) for biodiversity conservation in Mt. Jiri using the contingent valuation method (CVM). The WTP of respondents for the expansion of protected areas to increase biodiversity conservation was estimated at 16,103 KRW per household per year and this equates to a total of 316.8 billion KRW for all the households in Korea. The higher a respondent's age, education level and household income level, the more willing he or she is to pay for biodiversity conservation. Likewise, respondents who are aware of Mt. Jiri's designation as an Ecosystem and Landscape Conservation Area are more willing to pay for biodiversity conservation. Moreover, the higher the importance placed on biodiversity conservation policy, the higher the willingness to pay for biodiversity conservation. To enhance the feasibility of PES schemes, it is necessary to improve the general public's knowledge and awareness of biodiversity by providing opportunities for education and more information on biodiversity and biodiversity policies.
