  • It is difficult to make an accurate estimate of the economic value and effects on societal economy of Nano-technologies. This research measures an economic value of Nano-technologies quantitatively and analyzes its influences on societal economy. This paper chooses some major industries as analysis targets and adapts the DEFRA comparative methodology model which has been developed in the UK and recommended by OECD. For this reason, some industries which are in range of economic value assessment were investigated and related data were collected. Also, the economic value and societal influences of Nano-technologies were calculated, through the procedure of the model. In addition, this study conducts a questionnaire to experts for the validity of measurement results and procedures. This paper suggests a guideline for economic value and effects on societal economy of Nano-technologies assessments through quantitative Defra comparative methodologies.

  • 본 연구는 경제적 불확실성이 경영혁신에 미치는 영향을 분석하는 것을 목적으로 한다. 이를 위하여 관심변수인 경제적 불확실성은 Ahir et al.(2018)의 World Uncertainty Index(WUI) 지수로 측정하고, 경영혁신을 대용(proxy)하는 변수는 총연구개발투자(RD), 자산화된 연구개발투자(RD_A), 비용화된 연구개발투자(RD_E), 자산화된 연구개발투자비 중(RD_R)을 선정하였다. 연구결과, 경제적 불확실성(WUI)은 총연구개발투자(RD), 자산화된 연구개발투자(RD_A), 자산화된 연구개발투자비중(RD_R)과 통계적으로 유의한 양(+)의 관계가 나타났으며, 경영자의 기회주의적인 회계선택 행위(DACC; 재량적발생액)를 통제한 후에도 동일한 결과가 나타났다. 이러한 연구결과는 기업이 경제적 불확실성하에서도 연구개발투자에 집중하여 경영혁신의 기회로 활용한다는 것을 시사하며, 경제적 불확실성하에서 산업진흥을 위해 제공하는 정부지원의 타당성과 효과성을 밝히는데 의의가 있다.

  • 본 광역권별 경제력 비교분석은 정부의 지역경제정책에 대한 기초연구로서 콜드스타트(cold start)된 5+2광역경제권의 상이한 경제여건과 펀더멘털을 고찰하고 설정된 비교지표를 중심으로 전국 7대 광역권의 지역경제력을 비교 분석해 봄으로써 글로벌 경쟁력 확보 차원에서 자립적 광역경제권을 육성한다는 정부의 지역경제정책의 타당성과 향후 광역경제권의 정책방향을 고찰하는데 목적을 두고 있다. 경제력지수 비교결과, 수도권의 경제력지수가 절대 우위에 있는 반면 강원권, 호남권, 제주권은 상대적 열위상태인 것으로 조사되었다. 지역의 특성과 경제적 펀더멘털이 다르기 때문에 향후 지역발전 및 광역경제권 정책을 추진함에 있어서는 이를 고려한 세심한 배려와 발전계획 수립이 필요할 것으로 보인다. 그리고 정부는 지역경제여건을 감안한 광역경제권사업의 지역안배와 조정을 통하여 지역사업의 중복성 문제를 원천 차단함으로써 재정의 효율성을 제고시켜야 할 것이다. 또한 수요분석에 기초한 demand-based policy와 demand-pull policy, 지역낙후성을 감안하여 예산균등할(豫算均等割)정책보다는 비균등할 지원책을 탄력적으로 사용함으로써 지역균형발전을 도모하여야 할 것으로 사료된다.

  • The current method of rate adjustment for inflation is based on the evaluation of the financial performance of hospitals. The method has the disadvantage such as too complicated, expensive process as well as low reliability. This study, therefore, develops the 'Korean Medical Insurance Economic Index(MIEI)' as a new model for the rate adjustment with the use of the macro economic indices. In addition, we calculate the 1992∼1998 rate adjustment with the MIEI, and examines the validity of the MIEI by comparing with the conventional method. Medical costs are classified into nine categories : physician salaries, nurse·pharmacist·medical technician salaries, assistants & others salaries, material cost(by imports), material cost(by domestics), depreciation & rent paid(by imports), depreciation & rent paid(by domestics), power utilities, other administrative costs. Then the category weight which is the ratio of category in the total cost is calculated. Macro economic indices are selected for each cost category in order to reflect the concept of the each cost category and inflation during the year of 1992∼1998. Finally MIEI which integrate all category according to the category weight and selected macro indices is calculated. The mean of hospital MIEI which weighting by amount paid by insurers was cacluated. The result from the application of empirical data to the MIEI model is very similar to that of the current method. Furthermore, this method is very simple and also easy to get social consensus. This MIEI model can be replaced the current method based on the analysis of the financial performance for the adjustment of medical fees.

  • Humanity is facing a number of serious issues associated with increased energy consumption and environmental pollution. Various studies/guidelines concerning sustainable building construction have suggested solutions to these disastrous problems, including: net-zero energy buildings, the green building certification system, and others. Sustainability pursues three expected effects: environmental, social, and economic merits. Korean Green Building Council (K-GBC) has also announced the Korean Green Building Certification System (K-GBCS) since 2003 based on sustainability. Some positive social and environmental aspects of the K-GBCS have already been reported. However, it is somewhat difficult to verify its economic merits, which are crucial to ensuring the validity of the K-GBCS. This research aims to verify the economic merits of the eco-friendly Korean-style condominiums accredited by K-GBCS. Following this, the expected economic effectiveness of K-GBCS will be examined in terms of sustainability. The underlying assumption is that the potential economic effect should reflect the actual economic merits, and should reflect the value of the housing in particular. According to the analysis of the variance, it can be concluded the value of green certified buildings is statistically higher than the value of non-certified buildings. Furthermore, it was also observed that this tendency was more dominant in Gyeonggi Province than in the City of Seoul. This may be caused by one of the variables: the proximity to downtown. In future studies, this variable should be studied in greater detail.

  • Purpose: The objective of this study is to verify the economic validation of quality management integrated train freight car by analyzing economic evaluation indicators such as benefit and cost, net present value, and inter rate of return. Methods: First, we itemize benefit and cost field by reviewing literatures; Benefit consists of 1)Safety, 2)Operation, and 3)Maintenance; Cost consists of 1)Set-up fee, 2)Wireless internet fee, and 3)Cloud storage using fee. Second, based on these estimated values, we conduct an economic evaluation analysis. Among them, benefit and cost, net present value, and internal rate of return are selected. Results: As a result, all estimated values are highly over criterion of economic validity($$B/C{\geq}_-1$$, $$NPV{\geq}_-0$$, $$IRR{\geq}_-R$$); 1)benefit over cost ratio is 28.22, 2)Net present value is 8,121.66million KRW, and 3)Internal rate of return value is 2272%. Conclusion: The findings of this study will help making a decision when train industry adopts IoT technology for improving the effectiveness.

  • Green gas emissions Trading System(ETS) came into effect in the Europe last year 2005. All transport modes have tried to reduce green gas emission and EU member countries are promoting the use of environmental friendly transport mode to avoid economic loss due to green gas emission. Besides ETS, rapidly rising of oil price and peak oil urge to invest more in the environmental friendly public transport mode and to discourage the use of private cars. The operation of KTX is estimated to bring external cost reduction up to 570 bil. won in 2004 based on European external unit costs of transport modes. This result implies that the expansion of high speed rail network and reconsideration of East-West high speed rail network which is not considered because of weak economic validity is required.

  • This provided a basic frame to analyze the investment effect on the road, railroad, airport and port as a national dimension but it still has a limitation to analyze the specific economic and financial validities to consider the characteristics of the traffic facilities within the area. Conclusively, the aims of this study provide the reasonable evaluation guidelines effectively to the local automatic groups, especially Chungju in the frame of the present evaluation guidelines. We provide the adaptive alternatives on the present systems which are difficult to adapt to the present investment evaluation guidelines; the estimation method of the social economic index and the estimation method of the traffic demand. Additionally, we discuss the research method of the passage actual state for a reasonable estimation of the traffic demand. The result of this study will be activated for the validity check and construction plan of the reasonable traffic investment plan of Chungju city.
