The Korean government is planning to invest a lot of funds for conservation of the soil. Accordingly, it needs quantitative information on the soil. This paper attempts to analyze the total value of soil quantitatively: the total economic value of soil can be divided into use value and non-use value. To this end, we apply a replacement cost method (RCM) and contingent valuation method (CVM). Especially, CVM is most widely used to measure the non-use value such as environment goods. We employed the one-and-one-half-bounded dichotomous choice (OOHBDC) for willingness to pay (WTP) elicitation and a spike model. The monthly mean WTP was estimated to be KRW 3,949 per household for the next 10 years, which is statistically significant at the 1% level. Expanding the value to the relevant population gives us KRW 897.9 billion per year and as of the end of 2015, the non-use value of soil was assessed to be KRW 838.6 billion. Meanwhile, use value is subdivided into direct use value and indirect use value. This value was calculated KRW 3,277 trillion and KRW 51.8 trillion, respectively. As a result, total economic value of soil is estimated to be KRW 3,330 trillion in Korea.

The contingent valuation method (CVM) is one of the most commonly used and effective methods to evaluate non-use value of resources. Reasonable application of CVM to value the cultural heritage is the key process of evaluation. CVM was used to evaluate the non-use value of cultural heritage of Taishan Mountain combined with questionnaire survey and field research in this study. The results indicated that the importance of the degree of the three components of non-use value was heritage value ranked highest (40.22%) > followed by existence value (38.58%) >then option value (21.20%). In addition, the rate of willingness to pay was 54.52%, the average and median values of per person were 40.17 CNY·a^-1 and 20.00 CNY·a^-1 and the non-use values of Taishan Mountain cultural heritage was 33 million CNY·a^-1. The median value of WTP was consistent with Asian countries but was lower than European and American countries. Factors influencing WTP showed that monthly income and satisfaction with Taishan Mountain were correlated to WTP, and family location and willingness to revist were correlated remarkably with WTP. In addition, monthly income was correlated remarkably with WTP value, however other factors were not. The results showed the importance and necessity of protective development of Taishan Mountain cultural heritage, which would be used as an important reference for decision makers.

With the increasing concern about natural resources that is being devastated and lost its reproductivity, Non-use value of resources for future use is considered more important than the present use value in the resource valuation. This study aims to measure Total Non-use value in Namsan Park, Kwanak and Paldal Mountain with CVM(Contingent Valuation Method). CVM is the method which can evaluate Non-use value of tourism resource to find the future value of the given resource. This study is carried on the assumption that respondents give answers not to real situation but to imaginary circumstances. After analysing benefit value by estimating conservation value and separate use value, we can conclude that conservation value of tourism resource is given much weight.

This study estimated the non-use values of the Gum river estuary which are not related to the direct or indirect use of the Gum river estuary using the contingent valuation method (CVM). The non-use values of the Gum river estuary were explained and asked to be evaluated in the CVM questionnaire and estimates of the WTPs(willingness-to-pay) were elicited using the Turnbull nonparametric estimation methods on the dichotomous choice CV data. Results found the Turnbull lower bounded mean WTP per year for non-use value of the Gum river estuary was estimated at 5,822 won (95% C.I. 5,295 ~ 6,349 won) from single dichotomous CV data, and 6,205 won (95% C.I. 5,701 ~ 6,710 won) from double dichotomous CV data. The mean of two WTP estimates, 6,014 won (95% C.I. 5,498 ~ 6,529 won), was used to calculate the annual total non-use value of the Gum river estuary. Therefore, the non-use value of the Gum river estuary was estimated at 220.3 billion won (95% C.I. 201.4 - 239.2 billion won) annually. This non-use value of the Gum river estuary was composed of the bequest value totaling 68.3 billion won (95% C.I. 62.5 - 74.2 billion won), the existence value of 58.0 billion won (95% C.I. 53.0 - 63.0 billion won), the option value of 57.7 billion won (95% C.I. 52.7 - 62.6 billion won), and the vicarious consumption value totaling 36.3 billion won (95% C.I. 33.1 - 39.4 billion won).

This paper considers option and non-use values of rail services. The total economic value of a given transport service can be classified into use, option and non-use values, other grouping rules can be applied though. The use value is the consumer's surplus from the actual rides of a specific mode. The option value, on the other hand, can be defined as a traveler's willingness to pay for reserving a travel mode, which is not his or her main choice, as a standby alternative. Finally, the non-use value represents benefits that are not attributable to the actual use or option use, but to the vicarious, altruistic, functional and existing worth of a transport service. A stated preference survey based on a double-bounded dichotomous choice is conducted. A survival model is applied to the data collected. Calculations of trip makers' willingness to pay for option and non-use values are based on the parameters of the estimated survival model. Some suggestions for transport appraisal are also presented.

The valuation of biodiversity is a fundamental step in conservation. The useful framework for analysing the economic value of biological resources is that of total economic value (TEV) and TEV comprises both use and non-use values, the former related to an actual use made of the resource, the latter to a willingness to pay for the resource independently of any use made of it. There are several valuation approacher in environmental economics literature. However, stated preference approach should be introduced for valuation of biodiversity because it can estimate non-use value as well as use value. Contingent Valuation and Conjoint Analysis are representative methods in stated preference and Conjoint Analysis can be more useful for valuation of biodiversity. Futhermore, the combination of ecology and economics to assess biodiversity leads to an integrated framework. Thus, interdisciplinary work is required, involving both economists and ecologists transferring elements or even theories and models from one discipline to another and transforming them for their specific, mutually consistent purpose.

This study is to develope a user-based economic valuation methodology and model for the economic analysis on the DDS of foreign journals. For this study, the sampling data on the annual subscribed journals by K institution was used and the online questionnaire was used to collect data. There are three aspects of the economic value of DDS journals was classified as use value, non-use value, and expectancy value. We suggested the income and market approach to measure its economic use value. To estimate the its value by individual users, this study applied a contingent valuation method and designed the imaginary scenarios.

The traditional temples located in national parks have various functions, such as religious practice, tourist destination, and conservation for cultural and natural resources. One functions have implicit monetary values in terms of public benefits. The purpose of this study was to estimate both use and non-use conservation values for two traditional temples, Sinheungsa and Haeinsa, using the contingent valuation method. In the study, both single-bounded and double-bounded dichotomous choice methods were used in an application of Turnbull distribution-free model. A total of 659 visitors were interviewed, 350 in Sinheungsa and 309 in Haeinsa. The mean WTP (willingness to pay) for Sinheungsa using single-bounded method was 4,040 Won for the use value, 6,157 Won for the cultural conservation value, and 5,624 Won for the natural conservation value. The mean WTP for Haeinsa using single-bounded method was 6,463 Won for the use value, 8,769 Won for the cultural conservation value, and 8,013 Won for the natural conservation value. The total economic value of each temple accounted for 50% (Sinheungsa) and 80% (Haeinsa) of the total economic value of the associated national park. It was also found that the single-bounded method was more conservative than the double-bounded method in terms of value estimation. The WTP was highest for the cultural conservation value and lowest for the use values in both temples, with natural conservation values falling in the middle, which showed that people perceived traditional temples as the cultural heritage. Based on these results, it was suggested that traditional temples should be designated as an 'multiple heritage area' so that conservation can be used as the main criteria for various use programs.

Purpose : The aim was to compare the implant success rate according to membrane type through a clinical case of patients, who used bio-resorbable membrane and non-resorbable membrane. Methods : A survey was conducted targeting patients with the use of bio-resorbable membrane and non-resorbable membrane who visited H dental clinic in Busan for implant surgery and bone graft for 1 year from May 2010 to May 2011. A chart was made and surveyed for 100 people with non-resorbable membrane and for 75 people with bio-resorbable membrane. Results were compared. Results : 1. As for the measurement value of Periotest M${(R)}$, the value of -8~0 was measured with 92% in case of surgery by using non-resorbable membrane. The value of +1~+9 was measured with 8.0%. In case of surgery by using bio-resorbable membrane, Peiotest M(R) was measured with 78.7% as for the value of -8~0 and 16(21.3%) as for the value of +1~+9. In light of this, a case of using non-resorbable membrane was indicated to be higher(p=0.021) in success rate than a case of using bio-resorbable membrane. 2. As a result of periodontal conditions, namely, bleeding(p=0.914), swelling(p=0.500), inflammation(p=0.074), pain(p=0.571), and itch appearance(p=0.475) according to membrane type, all were insignificant. Conclusions : A case of using non-resorbable membrane is considered to be likely to be more effective than using bio-resorbable membrane during GBR(Guided Bone Regeneration) with the use of membrane in implant surgery.

Purpose - This study aims to develop a valid and appropriate method for measuring the economic value of intangible cultural resources. Design/methodology/approach - Building upon the concepts explored in many studies on the total value regulation of public goods or environmental goods, which are non-market value commodities, with a focus on the intangible cultural property Arirang, this study aims to formulate a new economic value concept for cultural resources that contributes to the overall economic total value, including non-use value. Based on this foundation, the study aim to identify and apply the most efficient model(CVM) among economic value measurement methods, as suggested by Tietenberg (2003). Findings - This involves estimating economic value through consumer behavior, encompassing the use or experience of cultural resources, as well as utilizing statements to estimate economic methods through consumer surveys. Only by presenting individual resource economic values of cultural resources in objective figures can a foundation be established for creating budgets and organizational structures to promote projects and policies. Research implications or Originality - Appropriate decisions can then be made by comparing these values with the expected costs in the management and planning process.
