This study focuses on (1) the relationship between the network intensity of top managers and the R&D investment of Korean firms, and (2) the moderating effects of the type (related-division vs. unrelated-division) and system (physical division vs. spin-offs) of corporate division on this relationship. The sample of this study was all type and/or system of corporate division implemented by Korean firms during 18-years (1999-2016) study periods. The results of multiple regression analyses as follow. First, as was expected in hypothesis 1 the network intensity of top managers has a strong positive linear relation with the R&D investment of Korean firms. Second, regarding the moderating effect of division type the results show that related-divisions significantly intensify the positive relationship of the network intensity of top managers with the R&D of Korean firms although unrelated-divisions did not. Third, in the analysis of moderating effect of corporate division system the results present the stronger positive moderating effect of spin-offs rather than physical divisions. The findings of the study implies that strong network intensity of top managers can be beneficial to long-term decision such as R&D investment of Korean firms. They accords to network theory that emphasize the importance of strong network effect among top managers based on their trust. The findings also implies that researchers and practitioners should consider organizational-level factors such as organizational structure, culture, corporate governance, etc as well as individual-level factors such as the characteristics and relationships of organizational members when making the decision for firm.

This study attempted to analyze technology convergence structure and key technology research sectors in bio-health. For this, network analysis was performed based on the patent outcomes achieved through national R&Ds. Then, a patent network was analyzed to derive problems and collect data from the National Science & Technology Information Service. With the five groups obtained through the analysis of IPC network and national R&D patents in bio-health based on a research frame network, topics were chosen based on the bio-healthcare technology system. Then, the technology with the greatest ripple effects was derived and compared to other sectors, suggesting a direction for national R&D investments. It is anticipated that this study would make a contribution to a search for R&D investment direction by additionally analyzing overseas patent data and improving correlation analysis between technology convergence and government-led R&D expenses.

네트워크 연결형 가상화스토리지 기술의 대표로서 SAN(Storage Area Network)와 NAS(Network Attached Storage) 및 IP SAN이 있다. NAS와 SAN은 시스템 통합, 빠르고 편리한 설치, 중앙 관리, 편리한 백업, 고가용성, 데이터 공유의 장점을 가지고 있다. 현재까지는 SAN 제품들 간 호환성 문제나 투자비용의 문제 등으로 인하여 시장 형성이 빠르지 못하나 SAN 환경에 대한 투자가 증가하고 있다. 그리고 앞으로는 서버 종속적인 가상화스토리지 시스템의 증가세는 둔화되고 NAS 또는 SAN의 가상화스토리지의 성장세가 지속될 것이다. 본 연구에서는 최근의 인터넷 환경으로 인한 컴퓨팅 환경의 변화에 따른 가상화스토리지 시스템에 대한 요구 사항의 분석과 이를 만족하기 위한 스토리지 기술과 네트워크 연결형 가상화스토리지 기술의 NAS와 SAN을 비교하며 네트워크 연결형 가상화스토리지 시스템에 관련된 표준화에 대하여 연구하였다.

최근 급변하는 세계 경제 환경에서 창업기업은 혁신, 고용 및 경제 활력의 핵심 동력으로 등장했다. 그러나 초기 창업 기업이 성장하는 여정에는 많은 어려움이 따르며, 이 과정에서 엔젤투자자의 역할이 필수적이다. 초기 창업 시장의 촉매제 역할을 하는 엔젤투자자는 필요한 자본을 제공할 뿐만 아니라 경영 노하우 및 네트워크를 통해 창업기업이 성공할 수 있도록 지원한다. 그러나 최근 데이터에 따르면 신생 기업 중 엔젤 투자의 혜택을 받는 기업은 1.4%에 불과한 것으로 나타나 창업기업의 잠재력과 지원 사이에는 분명한 공백이 존재한다. 이 연구는 지속가능한 경제 성장을 위해 창업 생태계의 중요한 요소인 엔젤투자자의 위험회피 성향을 이해함으로써 이들의 투자 행동, 의사결정 프로세스에 대한 통찰력을 얻을 수 있다. 위험회피가 엔젤투자에 미치는 영향을 알아보고 엔젤투자가 활성화 될 수 있는 방법을 제안하고자 한다. 본 연구를 통해 위험회피 성향이 엔젤투자에 대한 관심도와 실제 투자 활동 간의 관계를 추정해보고자 한다. 위험회피 성향이 엔젤투자자에 어떻게 영향을 미치는지 탐색하는 것에 중점을 두고, 엔젤투자자의 행동과 관심사에 영향을 미치는 다양한 요인들을 포함하여 진행한다. 연구 표본은 서울 및 경기 지역의 일반 성인과 엔젤투자자로 설문조사를 통해 필요한 데이터를 수집한다. 이 연구는 위험회피 성향이 엔젤투자 결정에 어떻게 반영되는지에 대한 깊은 이해를 제공하고, 엔젤투자 활성화를 위한 정책 및 전략을 수립하는데 중요한 통찰력을 제공할 것이다.

The investment environment in Korea and U.S. dramatically changed since Korea-US FTA. The key reasons for this successful change were liberalization and strengthened protection of investment along with trade liberalization which also brought investment market expansion. As the result of trade-diversion effect, investments between two countries have been enormously increased. Through a FTA with the big economy like US, Korea's FTA network has been largely expanded. Korea further needs to utilize this outcome when competing with other countries in investment markets.

We propose network effects upon the investment decision of cloud-based ERP. Using the survey data collected from 82 companies in 2015, we examine whether IT managers have an intention to adopt real options in order to manage the risk of cloud-based ERP investments and how the network effects influence upon the intention to adopt real options. Based on prior literature, we propose a research model with 4 hypotheses. We find partial support of the hypotheses from the empirical analysis: technological risks has a positive impact upon the adoption of real options such as defer, contract, and abandon. In contrast, we find no significant impact of security risks upon real options. We validate positive network effects upon the adoption of real options such as defer, contract, and abandon. This work empirically find that IT managers in Korean middle and small sized firms have an intention to adopt real options when the managers realize economic, technological, and relationship risks and when they expect network effects.

Since China opened its market to foreign investors, overseas Chinese firms have been the biggest foreign investors. Because of the uncertain market environment, other foreign finns incurred larger liabilities of foreignness than overseas Chinese finns. Some parts of liabilities of foreignness stem from cultural differences and last for quite long time. Therefore better understanding of Chinese culture and guanxi network can give overseas Chinese finns competitive advantages over those from other countries by offering market information and reducing transaction costs. Also better management skills, information about export markets and abundant capital allow them to maintain competitive strengths over local firms. As foreign firms accumulate market knowledge in China, they can reduce liabilities of foreignness. However, it is very difficult for foreigners to understand Chinese cultures and to utilize guanxi network as well as Chinese. It is likely that Overseas Chines firms can have competitive strengths in some industries such as banking, retailing, and foreign trade, where relationship with local contractors and exploitation of worldwide Chines networks can play important roles to make successful business deals.

This study considers an optimal investment planning for improving survivability from an air threat in the layered air defense system. To establish an optimization model, we first represent the layered air defense system as a network model, and then, present two optimization models minimizing the failure probability of counteracting an air threat subject to budget limitation, in which one deals with whether to invest and the other enables continuous investment on the subset of nodes. Nonlinear objective functions are linearized using log function, and we suggest dynamic programming algorithm and linear programing for solving the proposed models. After designing a layered air defense system based on a virtual scenario, we solve the two optimization problems and analyze the corresponding optimal solutions. This provides necessity and an approach for an effective investment planning of the layered air defense system.

In May 2004, Poland with nine other Eastern European countries joined the European Union(EU). After accession to the EU, Poland will accelerate the realization of investment in road sector, and wants to achieve important development of its road network condition in year 2005. Polish government is not able to afford the whole investment needed for construction of its motorways, so it wants to develop effective techniques of project funding based on the Public Private Partnerships(PPP). Without having high-performance transport networks, one country's economy cannot be competitive. It was the reason for establishing the Trans European Network(TEN) in the European Union. It creates the links, which are still missing between the fifteen countries of Western Europe and the new member countries like Poland. Consequently, Poland will also need to establish a proper transport infrastructure network. This paper will discuss how the PPP scheme can be applied for the transport infrastructure development in Poland as a EU member.
