In Korea, various community investment renewable project models are being implemented to increase community acceptance of renewable energy. An important factor for enhancing local acceptance is that renewable energy projects have a positive effect on revitalizing the local economy such as income increase or job creation for residents and local companies. To maximize the local economic effect of large-scale community investment renewable energy projects, this study developed an evaluation index for local economy activation, whose indicators are the local return on investment, local companies' participation, local job creation, regional cooperation, transparency, and governance. Analysis of existing evaluation indicators and current renewable projects, financial analysis, and expert interviews were used in this research. The pilot evaluation determined that, the local economic effect was high in the following order: a fund investment wind project (Gangwon), benefit-sharing wind project (Jeju), and general wind project. In particular, residents' investment amount, the number of participating residents, and the amount and transparency of the regional cooperation fund were key factors to expand the effect of local economy activation. This evaluation index could be used in public bidding for renewable energy projects such as offshore wind zoning areas of local government.

이 연구는 첨단화 융합화 복합화 경향이 특히 강한 정보통신 분야에서의 평가 신뢰성을 높이기 위해서는 평가의 전문성이 획기적으로 제고되어야 한다는 문제의식에서 출발하고 있다. 이를 위해 지식경제 기술혁신사업 중에서 정보통신 분야의 기반구축과 산업 진흥을 담당하는 정보통신산업진흥원의 평가 전문성을 평가자 선정, 평가자 전문성 발휘여건, 평가자의 이력관리라는 전 과정 평가관리의 분석틀을 활용하여 분석하였다. 분석 결과는 정보통신산업진흥원의 평가제도는 다른 기관에 비하여 평가자 선정과 평가자의 이력관리는 양호하나, 평가자의 전문성 발휘 여건은 상대적으로 개선과 보완이 필요한 것으로 나타났다. 이에 따라 각 분석요소에서의 평가 전문성 향상을 위한 정책대안을 단기와 장기로 분류하여 총 12가지로 논의하였다.

This paper shows the recent changes of national transportation policies in some developed countries and argues that the evaluation method of the effect of transportation investment on national economy should be improved to reveal real impact of the investment. The evaluation method should develope effective performance indicators of the goals set in national transportation policy. To estimate correctly the magnitude of transportation services in national economy, the evaluation method also provides a way to measure in-house transportation services and to overcome the limits of marginal effect equal equation.

최근 디지털 공유 경제가 사회에 가져다 줄 혜택에 대한 기대가 높다. 디지털 공유 경제가 정착되려면 신뢰할 수 있는 사회 구조가 우선 마련되어야 한다. 투명성은 정치나 경제 영역뿐 아니라 우리 삶의 모든 영역에서 가장 중요한 가치 척도로 인정받고 있고, 모든 국가가 '신용과 신뢰기반의 사회'를 지향하지만 현실 사회 곳곳에선 불투명과 부정 비리 비효율이 만연해 있다. 그러므로 신뢰하기 어려운 디지털 환경에 신뢰를 구축하기 위해 '제2의 인터넷 혁명'으로 불리는 블록체인 기술에 대한 관심이 고조되고 있다. 그러나 아직도 블록체인 기술을 평가하는 기준과 방법이 명확하지 않고 표준화되어 있지 않다. 본 연구에서는 디지털 공유 경제에 블록체인을 활용하기 위한 처리속도, 데이터량, 정확도 등의 블록체인 평가지표와 평가방법을 짚어보고, 블록체인 기반의 안전한 디지털 공유 경제 활성화 방안을 제시한다.

Life cycle cost is one of important factors in the evaluation of economy feasibility. Load carrying capacity curves for girders and decks are derived on the basis of bridge diagnostic results and condition grade curves to determine the service life and life cycle profile. The total life cycle costs including initial cost, damage cost, maintenance cost, user cost, and etc for the service life are calculated for steel box girder, PSC-I girder and rationalized plate girder. The optimal designs are performed for various service lifes and different superstructure types. The effects of parameters on the life cycle cost are investigated and the economy feasibility is evaluated through the sensitivity analysis.

The purpose of this study is analysis to vehicle's fuel economy and emission gas characteristics by fuel type. The test vehicle were selected to similar weight and performance, the test vehicle was used three representative mode(CVS-75, HWFET and NEDC) in order to evaluation fuel economy and emission gas. For reference, environment pollution cost was calculated on the basis of the exhaust emissions occurred in the test in progress.

Air transport is at the core of global economic growth. There is a close relationship between the flow of regional elements and the growth of the regional economy. It is easy to misestimate the impact of airports on the regional economy without considering spatial spillover effects. This study attempted to establish an asymmetric economic geographical weight matrix by applying the Spatial Durbin Model with cargo volume and passenger numbers as indicators. The influence of spillover effects on the regional economy, including direct spillover effects and indirect spillover effects are studied. The results revealed that passenger numbers and cargo volume have significant positive spillover effects on the regional economy. The driving effect of the airport on the regional economy was considered from a wider space scope. This study contributes to the scientific evaluation of the aviation economy.

Fuel economy is an important factor in a vehicle owing to recent energy supply and environmental problems. This paper deals with fuel cell hybrid vehicles (FCHVs) and introduces a fuel economy evaluation method. The fuel economy of an FCHV depends on its power management strategy. Two rule-based power management strategies are applied to this paper and their fuel economy is evaluated based on the optimal control theory. The concept of the optimal line is also applied to this paper, which is used to compare the fuel consumption of a power management strategy to the optimal result. The two rule-based strategies are also compared to each other.

An emergy evaluation of the natural environment ant economy of Seoul revealed that Seoul used 1.27 E23 sej/yr of emergy in 1997. The emergy input from the Han River accounted for most of the renewable emergy sources. Emergy imported from foreign countries and other parts of Korea accounted for 97% of the total emergy use in Seoul in 1997, revealing that the economy of Seoul is more dependent on outside emergy sources than for the entire Korean economy. The emergy use per unit area(2.09 E14 sej/$m^2$/yr) was higher than that for the entire country or Pusan, whereas the emergy use per capita(1.22 E16 sej/person/yr) was lower than that for the entire country or Pusan. These results reflect the overcrowded conditions in Seoul where about one fourth of the Korean population now live. They also seem to indicate a lower living standard in Seoul than the average in Korea. The quality of living in Seoul could also be judged by a high environmental loading ratio and a low sustainability index. All there indices suggest that people in Seoul live under a higher environmental stress than the average person in Korea.
