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.

It is critical to select an appropriate technology valuation method when the characteristics of a technology and valuation environment are variable. To ensure high quality decision making when selecting a technology valuation method, it is necessary to understand the principles of a good technology valuation method, and define and apply a decision making theory for selecting an optimal method. The authors propose that Axiomatic Design Principles can be applied as a decision making theory. In order to apply Axiomatic Design for this problem, this paper describes four domains(customer, functional, physical, and process domain) and four axioms(independence, information, cost, time axiom) for the decision making process for the optimal technology valuation method. The result of this study will contribute flexibility to the dynamic technology valuation process.

This study was to investigate categories of valuation and make the standard on developing valuation of natural dyes by Delphi method. The three-round Delphi tests were performed with 36 professional in the academic, the industrial, and the art field.'Dyeability property' meant levelling, adsorption, color diversity with mordant, color stability, 'marketability', possibility of mass production, economical efficiency, functionality, demand and supply of natural dyes, 'color', yield, beautiful color, value of color and 'color fastness', washing, perspiration and light fastness. Indigo, persimmon, cochineal, safflower and onion in dyeability property were evaluated highly, functional natural dyes in marketability, red and purple color ones except indigo in color and ones containing tannin in color fastness.

Functional values for wastewater treatment and atmospheric regulation in coastal wetland and rice paddy ecosystems are quantified, and an illustration is given on how to integrate biophysical parameters into a valuation framework. This is one of most controversial issues in economic analysis for wetland preservation versus wetland conversion to agricultural use. This paper includes theoretical considerations for estimating functional values of environmental ecosystems, and the integration of biophysical data and replacement cost method employed. Specific physical and geographical characteristics and data on ecosystem functions and services in coastal wetlands and rice paddies are addressed for evaluating their values in economic terms. In particular this paper indicates double counting problems and overestimation in the previous studies, and demonstrates how to avoid them and to maintain the consistency of valuation process involving a least-cost method, thus enables an accurate integration of the coastal wetland ecology and wetland economics. As a result which is far away from the previous studies, the total economic present value of wastewater assimilation by coastal wetland is estimated at 7,484,640 won/ha, and the net present value of positive effect for atmospheric regulation, negative effects for air pollution and water pollution by rice paddy is estimated at -37,934 won/ha, assuming that resources are infinitely long-lived and the annual value and the rate of discount (10%) is constant every year. In conclusion, for further reliability and validity of functional values for natural resources it is very noteworthy that a general equilibrium framework that could directly incorporate the interdependence between ecosystem functions and services would be preferred to the partial equilibrium framework.

Often in practice, the implied volatility of an option is calculated to find the option price tomorrow or the prices of, nearby' options. To show that one does not need to adhere to the Black- Scholes formula in this scheme, Figlewski has provided a new pricing formula and has shown that his, alternating passive model' performs as well as the Black-Scholes formula [8]. The Figlewski model was modified by Henderson et al. so that the formula would have no static arbitrage [10]. In this paper, we show how to construct a huge class of such static no arbitrage pricing functions, making use of distortions, coherent risk measures and the pricing theory in incomplete markets by Carr et al. [4]. Through this construction, we provide a more elaborate static no arbitrage pricing formula than Black-Sholes in the above scheme. Moreover, using our pricing formula, we find a volatility curve which fits with striking accuracy the synthetic data used by Henderson et al. [10].

자전거 도로 건설 같이 공공사업 성격이 강한 경우, 생활환경개선, 지역균형발전, 양호한 경관형성 등 다양한 도로기능 편익을 지니고 있는데 이들 항목은 기존 경제성 분석의 경우에서는 간과되는 측면이 있다. 이에 본 연구에서는 비시장재 가치를 평가하기 위하여 환경경제 분야에서 많이 적용하고 있는 조건부가치측정법(CVM : Contingent Valuation Method; 이하 CVM)을 이용하여, 실제로 자전거도로가 건설(해안선 자전거 일주 도로 건설의 예)됨으로써 발생하게 될 지역균형 발전 및 자전거 이용활성화를 고려하여, 시민들에게 직접 설문조사(전국 256가구)를 수행하고, CVM 방법론에 따른 지불의사액(Willing to Pay : WTP) 및 편익을 추정하였다. 그 결과 평균 WTP는 최소 2,114원 정도로 나타났다. 향후, 이러한 CVM 기법은 기존 경제성 분석을 활용한 편익 산출로는 한계가 있는 도로 건설 분야 중 도로교 건설에 따른 경관평가, 환경 개선에 따른 편익, 삶의 질 향상 등에 널리 활용될 수 있으리라 판단된다.

Engineering valuation is a specialized discipline requiring expert knowledge and judgment, which scientifically estimates the economic value of industrial properties. By industrial properties, we mean engineering structures such as mines, factories, buildings, machines, and other industrial facilities as well as facilities of public enterprises. Particular industrial properties can have longer economic life if their performance is excellent and they are still suitable for current manufacturing needs. If not, its economic life will be shorter. As speed of technological progress becomes rapid, life-cycle and development period of a product is becoming shorter. In an industry characterized by rapid development of technology, industrial properties can become obsolescent faster. Even if they are in good working order, they could be no longer suitable for manufacturing new products based on radically different technology. In our research, we apply engineering approach to estimating functional economic life by factoring in technological obsolescence in such an industry.

The purpose of this paper is to estimate the economic value of Multi-functionality Roles including landscape and so on, which traditional stone fences in Korea possess, using Dichotomous Choice Contingent Valuation Method (DC-CVM). The stone fences is life cultural heritance of regional residents. It has functions like Development of Favorable Landscapes, Maintenance of Cultural Heritage, and Recreation/Relaxation. Expectation from regional visitors shows that the existence and inheritance value of the stone wall is higher then we expected. According to the research that we had done from the people that had agreed to contribute the stone wall. moreover the public commercial value of regional tradition stone was not only 2,900 billion won but also it will increase an economic gain in every year. Therefore, preserving the stone wall that has Multi-functional Roles and values can lead to huge economic value in the future. But farmhouses in the stone wall conservation area are being supported 9 billion won in every year. This is only 0.03% of the income that farmhouse earns per year. Thus, stone wall preservation policy and plan can raise green-tour commercial value of inland area as a long-term inside measurement. Those will have to be propelled continuously.
