This research emphasized that the importance of green marketing activities elements such as green product, green price, green place, and green promotion. Moreover, it focused on verifying the effects of these four elements on purchase intention through environmental involvement. To verify this, an empirical analysis was conducted on Chinese consumers who have experienced or are considering purchasing a new energy vehicle. The research results are as follows. First, all four elements of green marketing activities improve environmental involvement. Second, environmental involvement was found to increase the level of purchase intention. Third, environmental involvement has a partial mediating effects in the relationship between the four elements of green marketing activities and purchase intention. Finally, the limitations of this study and future research directions were discussed.

This research emphasized the importance of consumers' perceived value and verified the mediating effect of innovation in the effect of consumers' perceived value on the purchase intention of new energy vehicles. To verify this, a survey was conducted on Chinese consumers. The verification results are as follows. First, it was verified that environmental value, social value, quality value, and economic value, which are sub-factors of perceived value, all have a significant positive effect on innovation. Second, it was found that innovation had a significant positive effect on purchase intention. Third, it was proved that innovation have partial mediating effects in the relationship between environmental values, social values, quality values, economic values, and purchase intention. Finally, the implications of this study result and future research directions were discussed.

This study compared finding economic and energy information on the WWW to finding the same information on DIALOG, a traditional search service. Professional searchers answered 20 questions for end users using either of DIALOG and one Internet database (general search engine or Web database). The relevance of the results in both sets of answers was ranked by searchers and end-users, respectively. The study found that searching for information on the Web took at least twice as long as it did when using DIALOG. Relevance rating was a little higher for materials found on DIALOG. However, the relevance rating difference between two systems was not so higher than we expected. From the research results, we conclude that Internet database including Web database and general search engines is providing valuable information of economic and energy subject areas.

A Commercial Grade Item Dedication(CGID) for Korean operating nuclear power plants has been implemented since 2012. The CGID implementation and strategies for Korea are established as follows: CGID policy establishment, R&D of a specific methodologies of CGID, enrollment of third party organizations for CGID work, CGID program establishment for enrolled suppliers, establishment of training courses for certification, and CGID process development for quality class Q and A. Consequently, it is expected that these activities are enable to enhance the reliability and the safety of components and/or parts in nuclear power plants.

최근들어 전산유체역학(CFD: Computational Fluid Dynamics)은 빌딩에 대하여 다양한 응용분야에서 사용된다. 이번 연구에서는 측정이 어려운 도심지 건물 군을 지나는 바람에 대하여 CFD해석 방법을 이용하여 고층 빌딩 상공을 지나가는 바람장을 예측 하였으며, 예측 된 결과를 실제 측정치와 비교 검증하였다. 바람장 측정 방법은 마스트를 세워서 측정하는 방법, 풍동 실험실에서 축소된 모형에 대한 실험방법, PIV 측정방법, LIDAR, SODAR측정 방법 등 많은 방법이 있다. 이번 연구에서는 가장 정확한 측정 방법인 LIDAR를 사용하여 측정을 수행하였다. 바람장이 측정된 장소는 서울 잠실 롯데 호텔 상공이며, 불어오는 바람은 롯데 월드를 중심으로 주변의 상가 건물들과 아파트 건물들 때문에 불안정하며 고르지 않을 것으로 예상되었다. LIDAR 측정은 일정 기간 동안 이루어 졌다. CFD해석은 임의의 시간대에 대해서 주 풍향에 대해서 해석이 수행되었다. CFD 해석결과는 최종적으로 측정 데이터와 비교 검증이 이루어 졌으며, 두 데이터간의 일치도가 높음을 알 수 있었다.

CASMO-3 코드의 기존 라이브러리들을 혼합핵연료 격자문제에 대한 검증계산을 수행하였다. CASMO-3 코드와 함께 도입되어 사용되고 있는 E4LIB-JA라이브러리는 플루토늄의 함량이 낮고, fissile 플루토늄 원소의 비율이 높은 조성의 혼합핵연료로 적용범위가 한정되었다. 혼합핵연료에 사용할 목적으로 Studsvik사가 수정한 40에너지군의 E4LIB-KA 라이브러리는 플루토늄의 함량이 약 12%이내로 제한되기는 하지만 비교적 혼합핵연료 계산에 유용한 것으로 나타났으나, 라이브러리의 개선된 내용이 구체적으로 알려지지 않아 앞으로 이를 사용자가 유지 관리하는데 문제점이 따르고 있다. 따라서 혼합핵연료 계산을 위하여 CASMO-3용 E63LIB/A 70에너지군 라이브러리를 ENDF/B-Ⅵ자료로부터 생산하였으며, 이를 알려진 혼합핵연료 임계실험자료를 대상으로 검증계산을 수행하여 그 유용성을 입증하였다.

철도 변전설비를 위한 싸이리스터 듀얼 컨버터 시스템은 기존의 다이오드 정류기로 구성된 변전설비 시스템과는 다르게 전동차 제동 시 발생하는 에너지를 안정적으로 계통(22.9kV)에 전달 가능하다. 본 논문에서는 싸이리스터 듀얼 컨버터의 실증 시험을 통해 기존에 제안된 제어기법을 검증하였다. 실증 시험의 경우 부산 호포 차량기지(전동차 6량 1편성) 시험용 전동차가 기동 시 싸이리스터 듀얼 컨버터에서는 882kW의 에너지를 공급하며, 제동 시 시험용 전동차에서 싸이리스터 듀얼 컨버터로 756kW의 에너지가 회생되는 것을 확인 및 분석하여 본 시스템의 타당성을 검증하였다.

The wind resource assessment for measured wind data over 1 year by using the meteorological mast should be a prerequisite for business feasibility of the wind farm development. Even though the direction of boom mounting the wind vane and anemometer is carefully engineered to escape the interference of wakes generated from the met-mast structures, the shadow effect is not completely avoided due to seasonal winds in the Korean Peninsula. The shadow effect should be properly calibrated because it is able to distort the wind resources. In this study a calibration method is introduced for the measured wind data at Julpo in Jeonbuk Province. Each sectoral terrain conditions along the selected wind direction nearby the met-mast is investigated, and the distorted wind data due to shadow effects can be calibrated effectively. The correction factor is adopted for quantitative calibration by carrying out the WindSim analysis.

'Low Carbon, Green Growth' may be the achievable target in industry section, depending on whether less reliance on fossil-fuels use can bring higher productivity growth in the long run. This paper tests for the short-run and long-run effects of investment on energy-saving equipments on productivity growth in the Korean manufacturing industries. The investment in energy efficiency causes an increase in costs (measurement effect) in the short-run, but in the long-run likely improve energy intensity and reduce costs (positive real effect) despite the delay in new other investment for technical innovation (negative real effect). A 2SLS regression was attempted to deal with endogeneity of energy-saving investment. The productivity effects were tested for five manufacturing sub-industries showing relatively high energy intensity with annual time series data from 1982 through 2006. No productivity effects were accepted for all five sub-industries except Chemical products. Positive real effect was considered to be exceeded by negative real effect, resulting in decreased productivity growth for Chemical products.

This paper aims to create standard forms of MRV plan and report, used when policy funds are applied in accordance with ESCO regulations, when energy savings are measured (the savings would be generated as energy users and ESCOs signed the contract of guarantee for energy savings, and energy saving facilities are installed following the contract). To fully reflect the goals and effects of the installation of energy saving facilities, MRV plans and reports will be completed for the purposes of measuring, verifying, and reporting if the goals of energy savings have been achieved successfully. In this paper, the forms of MRV plans and reports were developed with the detailed descriptions for each form and instructions of completion. Based on the developed forms of MRV plans and reports, future studies need to developed guidelines to explain how to fill out these forms considering the application cases by ESCO technology and facility.
