4차 산업혁명의 도래와 더불어 ICT 기계, ICT 금융, ICT 의료, ICT 나노 등과 같이 기술분야별 영역의 장벽이 허물어지고, 학제간 연구(Interdisplinary Research)가 일상화됨에 따라 국가 R&D 과제도 융합기술의 형태로 진화, 발전하고 있다. 부처별 R&D 과제의 결과물에 대한 성과평가는 현 시점에서 정성 평가지표에 대한 전문가의견법 결과를 참조하고 있으며, 일부 과제에 있어서 특허의 상태적 우위도(등급화) 결과를 반영하는데 머물러 있다. 본 연구에서는 과거 3~5년전 기술가치평가가 수행된 정부 R&D 과제에 대해, 가치평가 결과를 매출발생 시점 이후의 매출액 증감분과 비교 분석하여 시사점을 얻고자 한다. 특히 ICT 분야 R&D 과제로부터 산출된 기술적 성과(특허 10건 선정)에 대해, 해당 기술을 사업화한 주체(기업)의 매출액 실적을 비교하여 상호 관련성을 파악하고, 공공 R&D 과제의 평가관리 체계에 포함할 수 있는 실질적 개선 방안을 제시한다. 본 연구에서 제안된 기술가치평가 모형 및 참조정보 활용방안은 R&D 평가년도의 성과물에 대한 경제적 가치 수준 파악을 할 수 있는 평가툴이 되는 동시에, 차년도 국가 R&D 과제에 지원한 우수 기술 보유 기관의 미래 수익성을 파악하여 과제선정의 객관성을 높일 수 있는 정보지원툴로 활용할 수 있을 것으로 기대된다.

The purpose of this study is to study the perceived value of consumers of traditional Chinese music training institutions, and the resulting research on the impact of customers' purchase intentions. This research refers to relevant literature on customer perceived value and customer purchase intention, and divides customer perceived value into five value dimensions: emotion, quality, experience, price and reputation. Questionnaire survey method, using SPSS analysis AMOS tool to conduct empirical research, the research results show that customer perceived value has an important positive impact on purchase intention in five value dimensions of emotion, quality, price, experience and reputation, which is a traditional music training institution. Provide reference and suggestions for improvement.

There have been arguments in Korea that fair value accounting system improves quality of accounting information through the asset revaluation. These arguments are based on the fact that investors prefer fair value to cost value information. Others argue that cost principles may offer more proper information to the investors because financial statements applied the cost principles are more objective and thus more reliable. Prior researches focused mainly on the motives of asset revaluation but I examined the effects of the tangible asset revaluation on the stock prices. The empirical findings indicate that : (1) the gains on the tangible asset revaluation are positively correlated with the stock prices; (2) the net book values applied the cost principles explain stock prices better than the net book values applied fair values. My findings suggest that the gains on the tangible asset revaluation constitute a part of the firms' values but the accounting informations measured fair value are not always useful to the investors in the capital market.

본 연구는 공공재의 사회적가치 추정에 있어, 다가오는 21세기 정보ㆍ통신의 시대 도래와 함께 그 중요성이 더욱 증대될 전력을 대상으로 사회적가치 평가를 공급지장비라는 척도로 삼고, 그 속성과 추정방법에 대한 조사연구를 수행하였다. 공급지장비의 크기는 공급지장 크기와 지속시간, 발생시점, 발생빈도, 사전경고 여부, 소비자속성의 함수로, 추정방법은 크게 간접추정법, 시장정보조사법, 가상상황평가법으로 구분하였고, 이들 방법의 유용성을 필요 자료량, 자료 처리비, 입증성 등에 대해 비교하였다.

본 논문에서는 환경의 변화에 민감한 시계열 데이터인 주가의 변동과정을 보다 효과적으로 설명하기 위한 방안의 하나로 강화 학습 모형의 도입을 제안하며, 특정 시점의 주가 추세를 평가하는 기준으로 가치도 함수를 채택한다. 가치도 함수의 계산에는 강화 학습 알고리즘의 일종인 Monte Carlo 알고리즘을 적용하고, 신경망 구현에 의해 구한 근사 가치도의 적절성을 평가하였다. 실험 결과로 볼 때, 여타 강화 학습 알고리즘을 추가적으로 적용할 경우, 주가 변동의 시계열적 특성을 더욱 잘 반영할 수 있을 것으로 판단된다.

본 논문에서는 Internet Service Provider(이하 ISP)의 네트워크에 위험이 발생할 경우 위험의 출현으로 인한 ISP의 자산손실을 추정하는 방법을 제안한다. ISP의 네트워크를 구성하는 자산들의 가치를 서비스 측면에서 분석하고, 개별 자산이 생산하는 서비스 가치를 근사할 수 있는 방법론을 제시함으로써 네트워크의 장애로 인한 손실액을 추정 가능함을 보인다. 또한, 네트워크의 부하 분산, 우회 경로 및 백업 시스템 등 서비스 연속성을 확보를 위한 잉여 설계가 있을 경우, 자산가치 특성함수를 사용한 손실액 추정모델을 제안한다.

This study is analyzed using the Shanghai stock market and Shenzhen stock market data in order to analyze the usefulness of accounting information to appear from the introduction of international accounting standards in China. Summarized the relevant previous researches for objective study approach, studied the hypothesis based on the empirical analysis and set a hypothesis as adjusting the stuffs to fix in this research model. In this study, Analyzed the hypothesis to input of detailed variables for analyzing the value relevance between periods before fair value and after fair value. Also, in this hypothesis study, analyzed and estimated to affect the quality of information the acceptant period when compare with acceptant periods and before periods of fair value. These results suggested that impact the net asset value per share and earnings per share of the company because the value of the relationship had statistically significant at the level of relevance. Therefore, in the future studies about fair value assessment, will be expected that usefulness of the enterprise value evaluation method enable to discuss it such as critical sucess factors.

This study aims to present a new approach to measure the economic value of the public libraries, identifying and suggesting the modified contingent valuation method (CVM) application. The modified CVM, which applied Dissonance Minimizing (DM) format, is presented as a new approach. A cost-benefit analysis is used as a tool to determine if the benefits of public libraries outweigh the cost incurred in providing the services. The benefits of public libraries are based on estimates of how much the user is willing to pay for the library services and costs are based on the prices of providing the services. A comparison between two methods are conducted in a case study in order to measure the economic value of 'J Public Library'. The study also conducts a case study to analyse the WTP value of the 'J Public Library' and demonstrates how public libraries approach the their local studies.
