세계 각국은 과거부터 경제성장과 성장동력의 확보를 위해 꾸준히 외국인직접투자를 유치해왔으며 이는 우리나라도 예외가 아니다. 실제로, 각종 정책적 지원을 통해 양질의 투자를 유치하고 있고, 정부차원에서도 하나의 성과로 홍보하고 있다. 기존의 연구가 대부분 국가경제적 차원에서 외국인직접투자의 성과를 분석하고 있는 것에 그치고 있는 것에 착안, 본 연구는 이러한 외국인직접투자가 기업의 경영성과와 혁신성과에 긍정적인 효과를 미칠 것으로 가정하고 PSM 방법을 통해 실증분석을 하였다. 분석결과 매칭 전에는 외국인직접투자가 경영성과와 혁신성에 모두 양(+)의 효과를 미치는 것으로 나타났으나, 매칭 후에는 모두 통계적 유의성을 상실하여 외국인직접투자가 기업에 미치는 긍정적인 효과가 생각보다 부진하다는 것을 알 수 있었다. 이러한 분석결과는 정부의 외국인직접투자 인센티브 효과가 기대했던 것에 비해 적으며, 추후 정책에 대한 개선이 필요한 것으로 판단할 수 있다.

바이오가스화는 유기성폐기물을 안정적으로 분해하여 처리하는 과정에서 발생하는 메탄(CH₄)가스를 이용해 환경친화적인 연료를 생산하는 기술이다. 바이오가스화는 수분함량이 높은 유기성폐기물의 에너지화에 가장 많이 활용되는 방법이며, 직매립(2005) 및 해양투기(2013) 등의 금지에 따른 유기성폐기물 처리에 유용한 공법이다. 최근 국내에서 발병한 아프리카돼지열병(ASF, African Swine Fever)으로 습식사료화 재활용이 금지되고, 건조 사료화 및 퇴비화 등의 생산제품 수요처가 부정적으로 인식되면서 음식물류폐기물의 처리에 어려움을 겪고 있다. 이에, 음식물류폐기물의 처리 및 자원화를 위해 바이오가스화가 더욱 주목받고 있다. 우리나라 에너지소비 규모는 268.41 10⁶toe에 이르며 세계 9위 수준이다. 하지만 공급에너지의 약 95.8 %를 해외수입에 의존하고 있는 에너지 빈곤 국가이다. 따라서 국내에서는 신·재생에너지 공급의무화제도(RPS, Renewable energy portfolio standard)를 도입하고 있다. 국내의 RPS 제도는 다른 신재생에너지와 비교하여 폐기물에너지의 신·재생에너지 공급인증서(REC, Renewable energy certificate)의 가중치를 낮게 설정하고 있다. 따라서 폐자원에너지의 활성화를 위한 추가적 인센티브 제도가 요구된다. 본 연구에서는 음식물류폐기물, 음폐수 및 다양한 유기성폐기물이 처리되는 혐기소화조의 운영방식을 알아보고, 일정 기간의 정밀모니터링을 통해 폐자원에너지 인센티브제도를 마련하는 기초자료로써 활용하고자 하였다. 유기성 폐기물로 바이오가스를 생산하여 발전과 중질가스로 활용하는 4개소를 대상시설로 선정하였고, 현장조사 및 시료채취를 실시하였다. 채취된 유기성폐기물의 유입물 시료와 처리공정에 따른 유출물 시료의 기초 성상분석을 수행하였다. 성상분석 결과, 소화조 유입물의 총 고형물은 평 균 12.11 %이며, 총 고형물 중 휘발성 고형물은 85.86 %로 확인되었다. BOD와 CODcr 제거율은 소화조의 유입·유출 대비 각각 60.8 %와 64.8 %로 나타났으며, 유입물의 휘발성지방산은 평균 55,716 mg/L로 나타났으며, 혐기소화 후 감소율이 평균 92.3 %로 대부분 분해되어 제거된 것을 확인할 수 있다.

Introduction of BIM(Building Information Modeling) was led by public institutions, and all buildings over a certain size were obligated to apply BIM. However, through various attempt to apply BIM to actual practice, people had doubt whether it is a usable technology in reality appeared. Therefore, this study investigated cases about implementation strategies of foreign countries, and conducted survey on BIM performances and preparation in architectural design firms. On the basis of this, it suggests the long-term development strategy of BIM and the basic direction of road map to adopt BIM effectively to domestic architectural design market. After considering the cases abroad and the results of survey, it is identified that incentive policies supporting finance and education should be carried out together with partially obligation method led by government in order to introduce BIM into architectural design market effectively by reflecting current situation of architectural design firms.

This study takes an issue of efficiency analysis in the presence of network effect utilizing the DEA (Data Envelopment Analysis) framework. Network effect has important policy implication for the regulation of local monopolies which undertake their business through physical network, such as electricity, natural gas, local telephony, etc. If the difference in spatial condition between companies is not controlled properly, the performance comparison and associated incentive regulation bear significant bias. In this study, we propose a methodology to measure the true managerial or technical efficiency apart from efficiency difference accruing from the difference in spatial condition. A series of modified DEA efficiency models are combined to investigate the extent of exogenous and endogenous efficiency component in the Korean natural gas distribution companies. Empirical results show that the network effect plays significant role in determining superficial performance difference.

This paper addresses the bidding strategies of generating firms in a competitive market where the firms are provided with payment for generating reactive power. Reactive support for voltage control is an integral and critical part of power system operations. Since reactive support is unbundled in a competitive market under open access transmission, it is treated as one of ancillary services. The operation costs and opportunity costs for reactive support are compensated by payment to the firms, hence their bidding strategies will be affected. The opportunity costs are evaluated from the foregone profits of a generator in making sales in real power market by providing reactive support instead of real power. Game theory approach is used to analysis the transaction strategies of real power by the bimatrix method in this paper. Through computing the Nash equilibrium in a sample system, an incentive of a generator for improving the reactive generating capacity is found to be effective and the variations of the profits are analyzed as the demand power factor changes.

It is very necessary to find how to develop international government procurement by analyzing functions and roles of information providing circumstance and existing total international government procurement information system. In addition, it would require to draw up a way of improving current international government procurement information system based on the problems of existing system. In this study, we analyze the current status of Korean international government procurement information system and give an idea of mutual cooperating with DGMARKET, a good example of international government procurement information system. As a practical method, cooperating with DGMARKET by building each countries' gateway will be very helpful in cost saving and providing information. It will also complement the limitation of Korean system's one way service. But supplying only international government procurement information is insufficient in realization of e-trade in international goverment procurement market. To settle these problems, treating international government procurement as a same field of trade and giving political support and incentive to company which hopes to participate international goverment procurement are absolutely needed.

Purpose: This study aims to determine the conceptual properties of work engagement in nursing professional groups, and to provide basic data for nursing personnel management. Methods: To identify a nurse's work engagement, data were analyzed according to Walker & Avant's concept analysis method. Results: The analysis identified four work engagement attributes in nursing professional groups, namely: vigour, dedication, absorption, and zest. Conclusion: To bolster nurses' engagement with their duties, it is necessary to provide opportunities and implement interventions such as incentive system in performance evaluation based on work engagement in nursing, appropriate education program, and positive work environment.

It has become mandatory to designs by BIM in construction. It is urgent to make accurate decisions through the linkage between complex and various types of data in projects. In particular, block-chain based data sharing process (using BIM files, general construction submitted files) is essential to support reliable decision making in complex data flood systems. Prior to developing data sharing system based on block-chain, in this paper, a data linkage method is proposed so that practitioners can simultaneously utilize existing construction information and BIM data. Examples are shown based on the construction classification system and file expression, and incentive strategies are explored through a survey so that heterogeneous information can be used at the same time in overall projects.

The dramatic growth of social networking sites (SNS) has created a myriad of privacy concerns. Our study focuses on how much monetary incentive SNS users are willing to accept in exchange for disclosing their SNS information by accepting friend requests. First, we focused on information privacy in SNS, and estimated the value of information privacy by using the contingent valuation method. Second, we attempted to estimate how SNS users' willingness to accept would change when demographic information and additional information vary. Privacy-sensitive SNS users have the following characteristics: higher education, less SNS experience, and higher security consciousness. On the contrary, those who make good use of SNS and use open-based SNS are less sensitive to privacy. In summary, privacy-sensitive SNS users are fearful or uneasy when they have insufficient control of SNS information. Considering 14 conditions on the value of information privacy on SNS, the mean value of SNS information per person is 173,957 won. If we apply this value to Facebook users, the total Facebook information value would be 1.91 trillion won, considering that there are 11 million users in Korea.
