기술의 가치는 다양한 방법에 의해서 평가되어 지지만, 평가자의 주관과 평가 기법에 따라 상이한 결과를 초래하게 된다. 또한 평가 시 고려해야 할 요인 및 적용모형에 따라 결과의 불확실성이 생기게 되며, 특히 자료의 부족 또는 비교 대상이 없는 경우에는 평가 기술에 대한 가치 산정 결과의 신뢰성에 문제가 생길 수 있다. 이러한 평가 상의 불확실성을 감소시키기 위해 본 연구에서는 요인들에 대해 숫자(점수)로 평가하던 기존의 방식 대신 5가지 언어표현(아주 높음, 높음, 보통, 낮음, 아주 낮음)을 이용하는 퍼지 이론 및 이를 정량화 시킬 수 있는 퍼지 포괄 기법을 적용하여 특정 기술의 기술력을 측정하였다. 이를 위하여 국내에서 개발 중인 소음 저감 원천기술을 사례로 하여 기술성 요인과 사업성 요인으로 분류하고 기술의 가치를 평가 하였다. 기술성 요인은 높음, 사업성 요인은 아주 높음으로 평가되었으며, 이 요인들을 고려한 종합 평가에서는 아주 높음으로 평가되었다. 또한, 이는 각 요인별(세부요인, 대요인) 기술의 가치를 계량적으로 평가 할 수 있어 경쟁기술과의 요인별 비교에 도움이 될 것이다. 본 연구의 기법을 적용하면 다양한 분야에서 신규 기술(콘텐츠) 또는 대체 개발 기술(콘텐츠)과 같이 비교 자료가 부족한 경우에 기술력 분석 시 활용될 수 있을 것으로 기대된다.

Data can be considered a core driver of the Fourth Industrial Revolution, and databases are needed to create value by efficiently obtaining, storing and analyzing the data. However, there are currently no adequate valuation methods to handle databases. This study aims first, to understand databases as the subject of valuation and analyze value drivers of databases, and second, to propose a database valuation model based on this finding. To this end, we derive value drivers of databases from the characteristics and value criteria of databases observed in previous studies. Based on survey data from 396 database service firms we verify the value drivers through linear regression analysis. We find that the annual growth rate in database capacity and the data types positively affect sales of databases and offer ways to utilize them when estimating the cash flow, which is the variable to apply the discounted cash flow method-based income approach. This study contributes empirical insights into how to valuate databases considering their value drivers.

This study is to propose the ecosystem service valuation method as a complementary or alternative tool to overcome the limitations of the contingent valuation method(CVM), typically used to assess social benefits in preliminary feasibility studies. With an increasing interest in natural and environmental restoration projects, we assessed social benefits with theses CVM and ecosystem service valuation method from a case of Janghang wetland restoration project and compared the extent of the two social benefits. For quantitative evaluation of ecosystem services, the biophysical quantity for each ecosystem service indicator was calculated and then converted into currency (KRW) units to estimate the economic value of ecosystem services. The four ecosystem regulating service indicators were selected including greenhouse gas capture/storage, air pollution, water quantity and quality regulation. The amounts of CO₂ sequestration and storage as a ecosystem's greenhouse gas regulating service in the study area were 73.04 tCO₂/yr and 5,867.53 tCO₂/yr respectively. The reduction of SO₂, one of air pollutant gases by ecosystems was calculated to be 180.27 kg/yr, the reduction of NO₂ to be 378.90 kg/yr, and the reduction of fine dust (PM10) to be 9,713.92 kg/yr. The amount of freshwater regulating service by the ecosystem was estimated to be 459,394,319ℓ/yr, and the amount of nitrogen in freshwater removed by the ecosystem was 78.00kg/yr. Study results show that the benefits derived from the CVM were KRW 227.8 billion over the 30-year analysis period and those from the ecosystem service valuation method were KRW 41.4 billion for regulatory services and KRW 148.8 billion for cultural services, totaling KRW 189.5 billion. With KRW 184.8 billion of the total costs, the benefit/cost ratio using the CVM was 1.23 and that with the ecosystem service valuation method was 1.03. This study implications include that the CVM and ecosystem service valuation method can be applied together to assess and compare social benefits for natural and environmental restoration projects.

DMB data broadcasting has recently come into the spotlight as a platform for a new business opportunity and an application of various contents. This paper estimates the willingness to pay for the DMB data broadcasting services and explains the demand characteristics for TPEG, BIFS and BWS services, using the Double-bounded dichotomous choice Contingent Valuation Method. Consumers are willing to pay 2,039 Korean won for TPEG service and 1,612 Korean won for BIFS and BWS services per month, which corresponds to the market size 87.6 billion Korean won for TPEG and 195.2 billion Korean won for BWS and BIFS a year respectively. It is also found that the more consumers show usage intentions, have experiences in the similar services, and know of the DMB data broadcasting services, the more they are likely to pay for the DMB data broadcasting services.

The main purpose of this study is to estimate willingness to pay (WTP) by the general publics, assuming that they pay tax or charge for protecting marine living resources and environment through developing and supplying biodegradable fishing nets. This study employed a contingent valuation method (CVM) which is an econometric method. The survey was conducted by using both double-bounded dichotomous choice and open-ended survey. Tobit model was used for the analysis. The variables included concerns about marine environment and fishing net discarded, sex, age profile, number of family members, educational level and personal disposable income. Annual average WTP per family for the biodegradable fishing net development and supply was estimated at 5,294 won and national WTP amounted to some 84.2 billion won. This includes both of use and non-use value of biodegradable fishing nets.

Purpose - Aging and fewer economically active people have challenged the assumption of continuous population increases. A new real estate valuation methodology reflecting changes in population structure is thus needed. Research design, data, and methodology - The relationship between demographic change and changes in real estate prices is analyzed using ordinary least squares (OLS) to estimate the parameters, and a population structure change (PSC)-Binomial Option Model is developed to assess the volatility of the estimated parameters. Results based on Seoul and Shanghai data are compared. Results - Results of the DCF method indicate that investing in Seoul is better than investing in Shanghai, but the binomial option indicates the opposite. The PSC-binomial option model, reflecting changes in population structure, yields higher values (24.6 million won in Seoul and 43.3 million won in Shanghai) than those given by the binomial option model. Conclusions - This study indicates that applying changes in population structure to existing research, such as in the binomial option model, represents a more accurate real estate valuation method. Results demonstrate that the new model is more accurate than existing models such as the DCF or binomial option.

This study intended to estimate the willingness-to-pay amount by farmers for the automatic guidance technology of Combine. Contingent Valuation Method was employed for this estimation using survey data from 65 Combine using farmers. Based on the dichotomous choice model, farmers’willingness-to-pay for the automatic guidance technology was ranged from ￦4,772,000(median) to ￦5,268,000(mean). The estimated willingness-to-pay by the for the new technology was approximately one quarter of the average value based on the willingness-to-pay for the new technology was approximately one quarter of the average value of Combine in sample farms. This implies that there is an economic rationals for developing the new technology as long as it will be available with the cost less than the amount of estimated willingness-to-pay.

This paper proposes a new approach to technology valuation, the market-replacement cost approach which integrates the cost-based approach and market-based approach. The proposed approach estimates the market-replacement cost of a target technology using R&D costs of similar R&D projects previously conducted. Similar R&D projects are extracted from project database based on document similarity between project proposals and technology description of the target technology. R&D costs of similar R&D projects are adjusted by mirroring the rate of technological obsolescence and inflation. Market-replacement cost of the technology is then derived by calculating the weighted average of adjusted costs and similarity values of similar R&D projects. A case of "Prevention method and system for the diffusion of mobile malicious code" is presented to illustrate the proposed approach.
