Public-Private-Partnership(PPP) is becoming a popular form of projects in construction industry worldwide. Normally, the management team of PPP project consists of various experts from different disciplines such as construction engineer, bank financier, contract manager, investors, etc. The diversity of team members causes difficulties in managing the team efficiently and furthermore for the smooth execution of the project itself. One of the solutions to this issue might be the application of citizenship behavior by the team members. This study conducts an empirical investigation of the effect of project citizenship behavior on the project performance. We have collected data by using a questionnaire from those with PPP project experiences in the domestic construction industry. The results show that project citizenship behavior has full mediating effects between PM's leadership and the project performance. This study has an academic significance in that it is the first attempt to apply the concept and to show the effect of citizenship behavior in project management discipline, particularly in construction industry, in Korea. We also expect that the project management teams for PPP projects would benefit from the findings of this study.

In the past, because Korean private venture capital firms could get government support and subsidies, they could be survived in the market without having required management capabilities, advanced venture investment techniques, and professional supporting agencies and institutions. However, business environments have changed a lot recently. Now, only through identifying the optimal financial structures(the ratio of debt to equity), Korean private venture capital firms can minimize investment risks and ensure higher profits. Since Modigliani and Miller(1958) criticized the existence of the optimal financial structure, there have been numerous studies on the optimal financial structure of firms. However, there is no empirical study investigating the financial structure of venture capital firms. The purpose of this article is to analyze the relationship between firm characteristics, financial security indies, and financial profit indices of korean private venture capital firms. We gathered the data from various sources, including the web pages and the financial statements for 2003 and 2004. By using the student's t-test and the correlation analysis, we showed that there are differences in the current ratio and the ratio of net profit to net sales between new and old korean private venture capital firms. Even though it is known that korean private venture capital firms does not have enough knowledge and investment technique to compete with global venture capital firms, our result show that old korean private venture capital firms have already built some knowledge and understanding of venture capital investing.

A number of companies are considering for merger and acquisition (M&A) as one of business strategies for their growth and survival. However, many of them do not create the synergy they had sought, and failed M&A, often result in negative outcomes in terms of productivity, market share, profitability and turnover of qualified employees. There have been numerous research studies conducted to analyze the factors that determine the success and failure of M&A, and it has been found that with the increasing dependence of many companies on information systems, post-M&A IS (information systems) integration success has a critical effect on the success of M&A. However, there have been very few studies on post-M&A IS integration success, and most have been restricted to integration of IS organizations or physical information systems. In order to conduct a comprehensive research on the factors that affect the success of post-M&A IS integration, this study surveyed preceding researches on not only information systems but also strategic management, economics, finance, HRM (human resource management) and organization management. Based on the findings, a comprehensive and integrated model of the influential factors on post-M&A IS integration has been proposed. The proposed model categorizes the factors into perspectives of M&A, strategy, organization, HRM and IS, and provides an empirical evaluation of each factor on the success of IS integration based on comparative case studies.

Korea is concerned with information security industry due to recent leak-out private information of 3 card companies. Executives are aware of damage from breach of security such as personal data spill, is more dangerous than any other financial risks. The information security industry, which was limited in physical security and network security formerly, is evolving into convergence security of public and facility security industry. The field of interest has also been changed into security of smart phone and intelligence image recently, from firewall or Anti-virus. The convergence security is originally about access control of facility, but recently its demand has been increased mostly by public institutions and major companies. The scope of the industry also varies from finance, education, distribution, national defense, medical care to automobile industry. The market of convergence security has been expanded and new various products and services of security of intelligent vehicle, 'U' healthcare, finance, smart grid and key industries are also developed. It is required to create and enhance of new curriculum and cultivate human resources for the development of knowledge information security industry. Raising standard of education and security consciousness of the nation is also necessary to strengthen the global competitiveness.

During the recent years, cyber attacks have been increasing both in the private sector and the government. Those include the DDOS cases in 2009, the Blue House cyber attack, bank hackings etc. Cyber threats are becoming increasingly serious. However, there is no basic law related to cyber security at present, and regulations related to cyber security are scattered in various domestic laws. This can lead to confusion in the application of the law and difficult to grasp the regulations related to cyber security. In order to overcome this situation, the bill on the prevention and countermeasures against cyber crisis was initiated in 2006, but it has been abrogated. Since then, it has been repeatedly proposed, but it has been abrogated repeatedly due to the overlapping of existing laws and concerns about infringement of personal information. The most recent initiative was the National Cyber Security Act, which was initiated by the government in January 2017. The act focuses on resolving the absence of a basic law related to cyber security, strengthening its responsiveness in the event of a cyber security crisis, and fostering security strength. Therefore, this study seeks to contribute to the establishment of National Cyber Security legislation as a basic law of cyber security by examining the necessity of National Cyber Security legislation through comparative legal analysis with existing domestic laws related to cyber security and suggesting policy implications.

외환시장의 효율성을 증대시키고, 기업이나 금융기관들의 원/달러환율 변동위험관리가 보다 원활하게 이루어질 수 있도록 하며, 원/달러 환율과 연계된 다양한 투자전략 구사가 보다 용이하게 이루어질 수 있도록 하기 위하여 미국달러 선물시장과 미국달러 옵션시장에서의 유동성 확대 및 시장 활성화가 요구된다. 본 논문에서는 미국달러 선물시장과 미국달러 옵션시장의 유동성을 제고시키고 시장을 활성화 시키기 위한 방안들을 제시하였다. 미국달러선물의 만기시 최종결제와 미국달러옵션 만기시 옵션매입자가 옵션을 행사할 때 권리행사에 따른 결제는 실물인수도 방식으로 결제되며, 이러한 실물인수도 방식의 결제는 현물환 포지션을 취하여야 하는 불편함과 현물환 거래와 관련된 거래비용 등으로 인하여 투자자들의 시장 참여를 제약하는 주요 요인으로 작용하고 있다. 미국달러선물과 미국달러옵션의 만기시 결제방식을 현금결제 방식으로 바꾸게 되면 헤지거래자 등 투자자들의 참여가 확대되어 시장 유동성이 증대되고 시장이 활성화될 것이며, 차익거래자들도 적극적으로 참여하게 되어 시장의 효율성이 향상될 것이다. 그리고 미국달러선물과 미국달러옵션을 이용한 투자기법 및 투자전략에 대한 투자자들의 이해 수준을 높이고 환율변동위험 관리의 중요성에 대한 기업들의 인식을 제고시키기 위한 적극적인 노력이 요구되며, 중장기적으로 선물회사들의 지점망 확충과 선물거래소 회원사 확대 방안도 모색되어야 할 것이다. 미국달러 옵션은 거래가 매우 부진한 상태이므로 미국달러 옵션시장에서 유동성이 어느 정도 확보될 때까지는 선물회사들의 시장조성 기능 강화가 요구된다.주었다. 둘째, 주가 수익률을 결정하는 유의성있는 요인들은 당기순이익의 증감, 당해연도의 당기순이익의 분포, 자산증가율, 매매 유동성, 매출액 변동, 거래량 추세, 기업크기(시가총액), 과거 1개월간의 주가수익률, 자기자본증가율등으로 나타났다.이 있을 것으로 여겨진다.다중회귀분석에서 각각 일관되게 관찰할 수 있었다. 또한 이러한 결과는 IMF 이후에도 여전히 유지되는 것으로 나타났다.과와는 별개의 PER효과가 여전히 존재하며, 다만 이 PER 효과는 전통적 의미의 일반적으로 낮은 PER종목이 초과수익률을 내는 것이 아니라, 기업규모가 크더라도 그 기업의 개별특성을 고려했을 때 이와 비교해 상대적으로 PER가 낮은 종목에 투자하면 초과수익을 낼 수 있음을 의미한다. 발견하였다.적 일정하게 하는 소비행동을 목표로 삼고 소비와 투자에 대한 의사결정을 내리고 있음이 실증분석을 통하여 밝혀졌다. 투자자들은 무위험 자산과 위험성 자산을 동시에 고려하여 포트폴리오를 구성하는 투자활동을 행동에 옮기고 있다.서, Loser포트폴리오를 매수보유하는 반전거래전략이 Winner포트폴리오를 매수보유하는 계속거래전략보다 적합한 전략임을 알 수 있었다. 다섯째, Loser포트폴리오와 Winner포트폴리오를 각각 투자대상종목으로써 매수보유한 반전거래전략과 계속거래 전략에 대한 유용성을 비교검증한 Loser포트폴리오와 Winner포트폴리오 각각의 1개월 평균초과수익률에 의하면, 반전거래전략의 Loser포트폴리오가 계속거래전략의 Winner포트폴리오보다 약 5배정도의 높은 1개월 평균초과수익률을 실현하였고, 반전거래전략의 유용성을

This study analyzed the influencing factors for urban redevelopment projects with a relatively long project duration in the context of Seoul's increasing urbanization rate and aging. Among the business areas that have been designated since 2005 and have been approved for the management and disposal plan of the entire Seoul area, 75 business areas have been set as targets. A hedonic price model was used to analyze the project area, economic, and locational characteristics as independent variables with the project duration from designation of zones to approval of management and disposal plans as dependent variables. As a result of the analysis, the smaller the project area, the larger the area occupied per union member, the larger the land price change rate, and the smaller the KOSPI index, the shorter the required period. This study has the distinction of empirically analyzing the effect of characteristic variables considering size and economic and locational characteristics on period. It provides implications that the area of the business area, the number of union members, and economic conditions should be considered when establishing a business area.

North Korea's cyber capabilities represent a relatively new threat to global financial institutions and foreign governments, particularly the U.S and South Korean governments. Based primarily on publicly available sources, such as journalistic accounts and scholarly publications, this qualitative paper analyzes the ways in which North Korean leader Kim Jong Un has bolstered his country's asymmetric power and advanced his line of byungjin (dual development in the economy and military). Particularly by merging the cyber and maritime domains, North Korean operatives generate more revenue for the regime and helps keep the heavily sanctioned leadership in power. Despite the increased international attention to North Korean hackers, few analysts have examined the important role of cyber in the DPRK's internal political culture, specifically in advancing Kim Jong Un's byungjin line. Cyber fits into the DPRK's longstanding tradition of irregular warfare and guerilla-based armed struggle. Cyber also further advances Kim's personal reputation in the DPRK as an economic innovator and military strategist. This paper pays particular attention to the role of the DPRK's cyber operations in both ideological and maritime contexts. Recently, North Korean hackers have targeted South Korean shipbuilding industries and developed a blockchain scam, known as Marine Chain. North Korean cyber agents have increasingly paid attention to the nexus of cyber and maritime domains in their activities.
