FDI can either be absorbed in the production cycle with domestic investment and create an inducement effect or it can remain as an exogenous factor and increase the volatility of GDP. The purpose of this paper is to research these different impacts that FDI could have. For that, the endogenous growth theory was employed. The statistic method used are the panel model for sectoral analysis, and GARCH model and VAR for time series analysis. Myanmar was selected as this paper's research subject because it is one of countries which had a colossal amount of FDI inflow recently. The panel analysis did not confirm the causality between sectoral FDI and sectoral GDP. The reason for this could be in the lack of data, since sectoral data exists yearly only during 2006-2016. Therefore this study conducted the times series analysis. According to the results, during 2006 until 2010, it showed signs of GARCH but the effect of FDI on GDP was nonexistent, which means FDI was not integrated into the domestic production cycle but stayed in residual terms. During 2011 to 2016, FDI seemed to affect the growth of Myanmar's GDP. The estimation confirmed the existence of GARCH and the Granzer causality test confirmed that FDI influenced the GARCH, which signified FDI increased the volatility of GDP. The VAR analysis showed responses of GDP to FDI was small(about 0.0007). This research assumes that FDI can be divided in two parts: one part which can be assimilated in the domestic production cycle and the other where it stays outside of the production cycle. The former creates production inducement effect and the latter only increases the volatility of GDP. According to this study, the latter outweighs the former impact in Myanmar.

The purpose of this research is to propose a plan on migration policy based on features, through analyzing the migration adaption process and the farming life of the back-to-countryside population throughout the nation. For this, survey has been conducted to find out urban-to-rural migrants' motives and characteristics. The major reason for the migration was the household's financial condition, and the most of migration decisions were made by either one's spouse or parents. The migration fund was primarily spent in early agricultural activities and it was the neighbors who aided them the most whilst teaching them many farming techniques. Some government-supported policies are being highly demanded regarding the lower level of income (than urban life) and difficulties of raising cultivation funds; these two things are what migrants consider as the most inconvenient and suffering matters in farming life. Many surveyee have responded that they would constantly stay in the rural area and continue on their life as a farmer, giving a promising prospect for future farmland life. Based on these trends and features, development strategy regarding elaborate settlement plan of urban-to-rural migration is necessary.

BIM (Building Information Modeling) is a new paradigm that includes construction life-cycle, and BIM has become mandatory regulation according to the Public Procurement Service since 2016, which accelerates its application. BIM is now expand from architectural field to infrastructure industry. Through pilot projects, BIM has been challenged with verification process. This trend has affected to maintenance and operation (M&O) phase of construction life-cycle. Advanced country has already published their research and result with feasibility study and guidelines. In this paper, we conduct the feasibility study to adopt BIM-based infrastructure management system. Bridges and tunnels were selected as application target, and benefit/cost ratio were used. The result shows that BIM-based infrastructure management system is feasible when the level of detail is more than "Medium" in bridge, and "High" in tunnel.

제10회 아카시아 토론회가 본 협회(KIRA) 주최로 오는 9월 13일부터 17일까지 인터컨티넨탈호텔 국제회의장에서 개최된다. "아시아에서의 기술, 전통 그리고 건축"을 주제로 열리는 이번 토론회에는 우리나라를 비롯해 중국, 일본 등 아시아지역 16개 회원국 대표단과 행사관계자, 그리고 일반참가자 등 약 1천여명이 참가해 아시아지역 건축사들간 유대를 강화하고 주제 토론을 통한 기술교류 및 건축정보를 교환하게 된다. 5박6일간의 일정으로 진행될 이번 행사는 토론회와 함께 공식행사로 아카시아 이사회와 교육위원회 회의가 열리며 아시아건축상 시상식과 각종 전시회, 건축탐방, 한국건축소개 등 다양한 부대행사가 열린다. 특히 "건축문화의 해"를 맞아 개최되는 이번 ARCASIA Forum 행사에는 지명도가 높은 외국 건축사들이 상당수 우리나라를 찾을 것으로 예상돼 많은 건축인들의 관심이 모아지고 있으며 아울러 한국에서의 대규모 국제행사 개최를 계기로 침체돼 있는 우리 건축계에 활력을 불어넣고 한국건축의 위상을 한단계 끌어 올리는 기회가 될 것으로 보인다. 그동안 우리 협회는 88년아카시아대회를 제외하고는 국제관련 행사가 주로 외국에서 열렸던 관계로 직접적으로 행사에 관계했던 인사나 일부 관심있는 국내 건축사 이외에는 아카시아의 성격과 역할 등에 대한 이해가 부족했고 그만큼 관련행사에 대한 관심도가 적었던 것 같다. 그러나 국제사회는 국가간의 개방과 정책에 따라 사회 전 분야에 걸쳐 새로운 시도가 이루어지고 있으며, 건축관련부문은 민간사업뿐 아니고 정부 조달시장까지도 개방되어 외국 업체가 참여하고 있는 실정이다. 건축설계 또한 시장개방의 압력을 직간접적으로 받고 있을 뿐 아니라 그것이 점차 현실로 다가오고 있다. 이같은 상황에서 우리 건축계는 지속적인 국제교류를 통해 세계 건축시장이 어떻게 변화되고 있는지를 확인하고 그에 대한 정보를 토대로 적절한 대처가 필요한 상황이다. 그동안 아카시아는 회원국의 현안에 대해 서로의 정보교환과 토론이 있었으며, 아시아 각국의 입장을 대변하여 서방세계와 의견교환을 통해 지속적인 대화를 해 왔다. 이와 관련하여 본지에서는 ARCASIA Forum의 서울개최를 계기로 ARCASIA에 대한 독자 여러분의 이해를 돕고자 아카시아의 연혁과 성격 그리고 관련행사 및 회의구성 등을 요약하여 소개하고 또한 지난 85년 이후 우리 협회가 한국대표로 참가해 활동한 내용 등을 정리해 이번호부터 게재코자 한다.

The purpose of this study is to identify the determinants of new venture performance in the view of integrated research framework and to investigate key determinants of superior and inferior ventures. We propose the integrated new ventures performance model which is composed of entrepreneur, organization/resources, industrial environment, strategy/foundation process and availability of supporting systems as corresponding variables to new ventures performance. The superior venture performance is affected mainly by entrepreneur's managerial ability and industry expertise, but the inferior by resources and management strategy. Though this study has limitation of small sample, limited questionnaire and performance measure, it has contribution of identifying key determinants of new venture performance with the integrated frame of study.

Cloud computing helps big data processing to make various information using IT resources. The government has to start the RPS(Renewable Portfolio Standard) and induce the production of electricity using renewable energy equipment. And the government manages system to gather big data that is distributed geographically. The companies can purchase the REC(Renewable Energy Certificate) to other electricity generation companies to fill shortage among their duty from the system. Because of the RPS use voluntary competitive market in REC trade and the prices have the large variation, RPS is necessary to predict the equitable REC price using RPS big data. This paper proposed REC price prediction method base on fuzzy logic using the price trend and trading condition infra in REC market, that is modeled in cloud computing environment. Cloud computing helps to analyze correlation and variables that act on REC price within RPS big data and the analysis can be predict REC price by simulation. Fuzzy logic presents balanced REC average trading prices using the trading quantity and price. The model presents REC average trading price using the trading quantity and price and the method helps induce well-converged price in the long run in cloud computing environment.

교통사고가 중요한 사회 문제로 대두되어 정부는 교통안전대책의 실질적인 추진 방안으로 "교통사고 잦은 곳"과 "위험도로" 개선사업을 제시·시행하고 있다. 이에 "교통사고 잦은 곳" 개선사업은 추진현황에 따라 각 년도별 기본 개선계획의 평가 및 경제적 타당성에 대한 효과분석이 이루어지고 있다. "위험도로"'의 경우 모든 사업을 건설교통부 산하 국도유지사무소에서 진행을 하고 있으나, 광범위한 사업으로 인한 업무과중 및 개선사업비 조달 등의 문제로 개선된 현황의 체계적인 효과분석이 이루어지지 못하고 있는 실정이다. 이에 따라 본 연구에서는 "위험도로" 개선사업에 대한 효과분석을 수행하여 보다 비용-효율적인 개선사업이 될 수 있는 기반을 마련하고자 한다. 이를 위해 전체 위험도로 구간 중에서 '광주국도유지사무소' 및 '순천국도유지사무소' 관할 구역 내의 "위험도로"로 선정(1995년)된 도로구간 중 1999년 이전에 도로개선공사가 완료된 후 현재 교통소통이 원활하게 진행되는 18개 도로구간을 연구 대상으로 선택하였다. 선택되어진 18개 구간에 대한 도로개선공사 전후의 교통사고건수 및 교통사고율을 효과척도로 삼고 각 사고에 대한 소요비용을 기준으로 경제성 평가를 실시하였다. 이를 근거로 "위험도로" 개선사업에 대한 타당성조사 및 효과분석을 실시한 결과 "위험도로" 개선사업의 타당성이 입증되었다. 연구 분석결과가 전라도 권역의 사업을 중심으로 진행되어져 전국적인 개선사업에 대한 대표성을 가지고 있다고 볼 수는 없으나, 체계적인 분석을 통한 개선사업의 효과를 구체화 할 수 있는 대안을 제시할 수 있을 것으로 사료된다. 더불어 공사 완료된 도로구간에 대한 상세한 공사비 내역과 다수의 개선방안별 자료가 갖추어지면 위험도로의 사고율과 개선방안별 상관관계를 관련 비용을 중심으로 도출함으로서 비용-효율적인 개선 방안을 제시할 수 있을 것이다. 또한 비용-효율적인 개선 방안을 기반으로 한 각각의 사업 투자우선 순위 결정방안에 관한 지속적 인 연구가 요망된다.
