Korea has recently experienced a large change in civil architecture and urban environment. However most of civil architectures and urbanization have been accomplished without considering economic efficiency and impact. This study focuses primarily on an analysis on the relationship between architecture and economic efficiency through the foreign and domestic case studies. Secondly, it is going to elucidate the economic properties on Korean architecture recently established. With perspectives of the analysis, we need to consider the following factors in the production of architecture; labor intensive industry, seasonal industry, strong and domestic demand.

The demand for demolition of steel structures is recently increasing in Korea. Most of flexible linear-shaped charges(FLSC) for steel demolition are now imported from foreign countries. Some basic experiments have been studied to determine the optimum parameters of design for domestic development of FLSC. Domestic FLSC were used to check cutting of steel structures and other materials in this study. The result shows that domestic FLSC is very effective to cut steel structures.

The introduction of BIM-based project has increased in the domestic recently. Therefore the demand of BIM professionals is surging combined with the necessity of BIM education. However BIM education done in the domestic industry and public organization is only focusing on the 3D modeling, As a result an educatee could not put the real intention of BIM into practice. Thus through this study the wrong recognition of BIM will be corrected and this study analyzes the problems of domestic BIM-based project. This study examines the improvement of domestic BIM education cases by drawing the capability of BIM professionals.

The aims of this study are to provide future prospects of the Korean ornamental fish industry and to seek for its development direction based on analysis of its problems and its domestic and foreign situations and circumstances. The ornamental fish market has continuously grown due to increase of domestic and international demand. In this respect, the Korean ornamental fish industry has also high potential. However, the industry still has several problems such as artisanal industrial structure, a lack of investment related with R&D, poor information on the domestic and international ornamental fish industry, underdeveloped regulations and policies, low public awareness and less effort to expand the market, and a lack of regulatory and policy support. Therefore, overcoming these problems above, the Korean government has to carry out following things : establishment of institutional and industrial foundation, intensive R&D investment, exploitation of domestic and foreign markets, and systematic information gathering for ornamental fish industry.

Recently, ESG bond issuance has been gradually spreading to banks and non-financial private companies in Korea. However, the Korean ESG bond market is still in its infancy in terms of size, diversity and investor base compared to the global ESG bond market. In other words, ESG bonds are rapidly forming in the global market, but are still in the formation stage in the domestic market, and various policy and practical measures such as system, incentives, and infrastructure are needed to activate them. In this paper, we examine the domestic and international status of ESG bonds in relation to responsible investment. In addition, this paper explores specific measures to revitalize the domestic ESG bond market in four aspects: establishing ESG bond standards, procedures and regulations, increasing ESG bond investment demand, increasing ESG bond issuance, building market infrastructure and market efforts. This study is expected to contribute to the development of the domestic ESG bond market and responsible investment.

A survey was conducted on the awareness and demand for the Multi-crew Pilot License (MPL) to prepare the legal institutional basis for the MPL certification system. A total of 288 airmen were asked questions about the awareness and demand of the MPL certification system, and factors affecting the establishment and participation of MPL training programs. The survey results show the understanding of the MPL certification system is significantly lower than that of the current pilot certification system. The demand for the MPL training program was found to be significant, trainees and low-skilled airmen was greater demand. The factor that has the greatest influence on the establishment and participation of the MPL training program was identified as employment connection (airline recruiting). It is expected that the result of this study will be used as basic data necessary for establishing MPL certification system policy.

Explicitly spatially distributed and reliable data on industrial water demand is very much important for both policy makers and researchers in order to carry a region-specific analysis of water resources management. However, such type of data remains scarce particularly in underdeveloped and developing countries. Current research is limited in using different spatially available socio-economic, climate data and geographical data from different sources in accordance to predict industrial water demand at finer resolution. This study proposes a random forest regression (RFR) model to predict the industrial water demand at 0.50× 0.50 spatial resolution by combining various features extracted from multiple data sources. The dataset used here include National Polar-orbiting Partnership (NPP)/Visible Infrared Imaging Radiometer Suite (VIIRS) night-time light (NTL), Global Power Plant database, AQUASTAT country-wise industrial water use data, Elevation data, Gross Domestic Product (GDP), Road density, Crop land, Population, Precipitation, Temperature, and Aridity. Compared with traditional regression algorithms, RF shows the advantages of high prediction accuracy, not requiring assumptions of a prior probability distribution, and the capacity to analyses variable importance. The final RF model was fitted using the parameter settings of ntree = 300 and mtry = 2. As a result, determinate coefficients value of 0.547 is achieved. The variable importance of the independent variables e.g. night light data, elevation data, GDP and population data used in the training purpose of RF model plays the major role in predicting the industrial water demand.

원자력 인력 고령화는 원전 수출에 따른 새로운 인력 수요 증가에 못지 않는 중요한 인력 문제를 야기할 수 있다. 고령화된 숙련 전문인력의 대거 퇴직에 따른 고급 인력난과 원자력 기술능력 약화는 한국 원자력의 경쟁력을 크게 약화시킬 수 있다. 본 연구는 한국 원자력 관련 기관 및 업체들에 대해 2001년과 2010년 국내원자력 기관의 인력 현황에 대한 통계조사에 근거하여 약 10년의 기간 동안 원자력 인력 변동 추이 등의 인력 현황 통계자료를 활용했다. 이를 토대로 조사대상 기관별로 그리고 통합적으로 원자력 인력의 고령화 수준을 검토한다. 그리고 원자력 인력 고령화 문제에 대비하기 위한 인력 충원의 방향과 한국 원자력 인력 수급의 문제점을 해소해 나가기 위한 대응방안을 제시할 것이다.

개념적 집중형 일 유출모형인 DAWAST모형을 선정하여 용수수요를 고려할 수 있는 가능성을 검토하였다. 기존 모형에 의한 모의 유량을 자연유량으로 보았고, 농업용수, 생활용수, 공업용수 등 회귀수량을 더한 값을 하천유량으로 가정하였다. 농업용수의 수요량은 회귀수량이 논으로부터만 발생하는 것으로 보아 논 용수량만을 고려하였으며, 수정 Penman공식에 의한 증발산량, 침투량, 재배관리수량, 유효우량 등을 고려한 일별 감수심에 의해 일별로 계산하였다. 생활용수, 공업용수 수요량은 일 평균값에 월별 변동계수를 고려하여 일별로 계산하였다. 신뢰도가 높은 대청댐 운영실적의 유입량 자료를 이용하여 용수수요를 고려한 DAWAST 모형의 적용성을 평가하였다. 농업용수의 회귀율은 35%, 생공용수의 회귀율은 65% 적용하였으며, 1983년∼2001년 연평균하여 강우량 1184.6 mm 관측 유입량 667.3 mm 모의 유입량 652.6 mm 로 용수수요를 고려하지 않은 경우의 모의 유입량 606.8 mm에 비해 45.8 mm 가 높게 나타났으며, 모의/관측 유입량 비율도 90.9 % 에서 97.8% 로 개선되는 결과를 얻었다.
