Open innovation is known to have a significant impact on the performance of enterprise innovation. The role of open innovation is more critical due to small scale and limitation on the available resources for the venture company. This study focused on the relationship among Entrepreneurship(ENT), Innovation Capability(IC), and External Cooperation(EC), which affect Technological Innovation Performance(TIP) to maximize TIP. Empirical study was proceeded to analyze the relationships among ENT, IC, EC, and TIP for venture companies in Busan. ENT was verified to have a positive impact on IC, EC, and TIP. IC was done on EC and TIP. EC was done on TIP. Each of IC and EC showed positive mediating role in the relationship between ENT and TIP. Finally, IC and EC together performed positive mediating role in the relationship between ENT and TIC.

External linkages affect the performance of small and medium enterprises in diverse ways. This study delves into the impact of inter-organizational collaboration by looking at different facets of performance, such as innovation, sales growth, profit growth, and firm survival. In addition, it explores the influence of informal knowledge spillover from collaborative partners as well as from formal collaborations. The impact is carefully investigated by dividing firm samples into three different sectoral innovation categories: supplier-dominant, production-intensive, and science-based sector suggested by Pavitt (1984). The result highlights the different influence pattern of collaborative relations by partner types according to sectoral categories. The positive results of collaborating with universities and public institutions are identified, and the sales growth by customer linkage is witnessed. The impact is apparent in science-based sectors. The result implies that the risk associated with collaborating with competitors may be moderated by linking performance enhancing collaborative linkages with universities and government institutes.

The paper analyzes the effects of Korean venture businesses' external collaborations on their innovation performances, according to their collaboration partners and collaboration activities. The results show that the collaborations between Korean venture businesses and research institutions, and those between venture businesses and other venture businesses have significant positive effects on venture businesses' innovation performances, in terms of the numbers of the intellectual property rights, while the collaborations between venture businesses and large companies have significant positive effects on medium-sized venture businesses only. In addition, collaborative research and development, and technology transfer from big companies to venture businesses have given significant positive effects on venture businesses' innovation performances, while collaborative employee training and collaborative marketing have given significant negative effects on venture businesses' innovation performances. Furthermore, collaborations between large companies and their subcontracting venture businesses have shown even more significant effects on venture businesses' performances. The results show that the effectiveness of external collaborations of Korean venture businesses depends on collaboration partners, types of collaboration activities, and the size of collaborating venture businesses, implying that government programs for encouraging venture businesses to collaborate with external institutions should be carefully chosen for their innovation performance improvement.

The purpose of this study is to investigate the external collaboration factors that affect the performance of Korean venture businesses. We use 1,567 firm data (from Venture Business Survey by Small & Medium Business Administration) and analyze the effect of the external collaborations with large business, research institutions, other small business, and foreign companies, on their sales increase between 2008 and 2009. Our analysis shows that Korean venture business' collaborations with research institutions or foreign companies increase their sales statistically significantly, while their collaborations with large business decrease their sales significantly. In the mean time, their collaborations with other small businesses show no significant result. Additional analysis on the collaboration categories between venture businesses and large businesses shows that collaborative R&D, employee training and collaborative marketing help venture business to increase their sales significantly, while financial collaborations have a significant negative effect on sales increase. Technology transfers and profit-sharing mechanism have no significant effect. The result shows that venture business' collaborations for the increase in the fundamental capability of innovations and for searching new markets rather than simple transfer of technology or financial collaborations, have significant positive effects on the increase in sales.

최근 이러닝의 발전과 함께 다양한 표준들이 주목받고 있으며 그중에서도 SCORM 표준은 자기 주도적 학습 중심에 초점을 두고 있으므로 협력학습을 지원하기 위해서는 외부 도구를 별도로 이용해야 한다. 하지만 IMS LD 표준에서는 협력 학습을 지원하기 위해 컨퍼런스 서비스를 이용하여 콘텐츠를 저작할 수 있으며, 컨퍼런스 서비스는 LD 실행 엔진에 포함되어 실행되거나 외부 도구로 실행될 수 있도록 유연성을 제공한다. 이에 본 논문에서는 LD 표준에 기반하여 협력 학습을 실행 엔진 내부에서 지원할 수 있도록 개발된 내용에 대하여 설명할 것이다. 개발된 LD 실행 엔진은 LD 표준을 준수하며, LD 콘텐츠에 기술된 협력 학습 설계 내용에 따라 협력 학습을 진행할 수 있어 설정된 역할에 따라 협력 학습에서의 권한을 달리하여 협력 학습을 진행할 수 있다는 특징을 가지고 있다.

In this paper, we propose out-of -band collaborative spectrum sensing scheme in the cognitive radio (CR) base station operated by the multiple frequency channels. Also this paper presents the signal detection results for ATSC digital TV signal as an incumbent signal and derives signal detection probability and false alarm probability for the out-of-band collaborative spectrum sensing scheme in frequency selective Rayleigh fading channel. Numerical results demonstrate that the sensing performance is improved by the out-of-band collaborative spectrum sensing in the case that the incumbent signal powers measured by the CR terminals of the multiple frequency channels are almost similar.

With a view to deepening the research stream on the factors positively influencing the export growth and the employment increase of South Korean small and medium companies, this research has developed the research model about the impact of small and medium companies' external technology R&D collaboration network heterogeneity on their export growth and employment increase, and has empirically tested the research model with the 2,200 data collected from the small and medium companies in the South Korea. This study illuminates the two points from the empirical testing results. One point is that small and medium companies' external technology R&D collaboration network heterogeneity significantly and positively influences their employment increase from technology development. The other point is that small and medium companies' export growth from technology R&D partially mediates the impact of the external technology R&D collaboration network heterogeneity on their employment increase from technology R&D.

Firm’s social network has been known as an important firm strategy because it could promote technological innovation and also minimize economic uncertainty. In this study, we identify four types of firm’s social network activities such as Collaboration, Manufacturing/Marketing/Distribution Agreements, Financing, and M&A, and analyze how these activities affect firm performance using U.S biotechnology firm data. We found that Manufacturing/Marketing/Distribution Agreements increased firm performance in short-run. Also, collaboration with pharmaceutical and biotechnology firms had a positive effect on firm performance, too. However, collaboration with public institutes or universities had a negative effect on firm performance in short run, which implies its collaboration would be mainly focused on research in pure science area. These empirical results provide two policy implications. First, social network strategy should be encouraged in the Korean biotechnology industry. Secondly, governments should consider developing polices that support collaboration of biotechnology with public institutes or universities, to promote technological innovation.
