In this paper, the structural characteristics of Industry-University cooperation networks are analyzed using network analysis. Recent studies have shown that technological cooperation and joint research has a positive effect on R&D performance. In order to boost innovation performance, various types of cooperative activities and governmental policy supports for major R&D stakeholders(i.e. universities, laboratories, etc.) are provided. However, despite these efforts, the outcome is still insufficient, so it is time to prepare for a plan to build an innovative network to strengthen university-centered Industry-University cooperation activities. Specifically, this study builds the networks according to the form of Industry-University cooperations(i.e. patent, paper, joint research, and technology transfer), and different types of Industry-University cooperation networks are analyzed from a statistical viewpoint by using QAP correlation and regression analyses. The analysis results show that joint research network is closely related to paper network, and is related to other Industry-University cooperation networks. This study is expected to shed a light on supporting innovation activities such as establishing Industry-University cooperation strategies and discovering cooperative partners necessary for creating new growth engines for universities.

Recently many companies build interfirms cooperation based on their trust. These typology of partnerships play important roles for good results especially for joint product development. Therefore the purpose of this article is to investigate the role of interfirms communication in B2B market. We also investigate interfirms communication affecting the result of new product performance through two relationship factors(trust, conflict) in B2B market. Data were gathered from respondents who work in industrial buying center. Major findings of this study are summarized as follows: First, communication has positive effects on trust but negative effects on conflict. Second, trust is shown to have positive effects on cooperation and new product performance. However, conflict is shown to have negative effects on cooperation and new product performance. As a result, interfirms communication derives new product performance. In conclusion, this study means that we tried to investigate the human relationship in B2B market.

Using small and medium sized firms located on 3th seongseo industry complex in Daegu, this study investigated the effects of technology development factors on innovation performance, and suggested the implications in terms of technology policies. Technology development factors are categorized into both fundamental based factors and external cooperation based factors as independent variables. According to the research results, external cooperation based factor positively affects innovation performance, and this positive effect is reported in firms having more than average firm size. Under environment uncertainty, external cooperation based factor plays a key role to increase innovation performance to firms having more than average firm size. Therefore, policy making should be focused on external cooperation, not on fundamental base such as people and infrastructure, and also dissimilar policy suggestion based firm size is needed to be considered.

In this paper, we propose a new adaptive cooperation scheme with multi-relay nodes which achieves higher performance and spectral efficiency than that of some conventional cooperative schemes. The relay-selection is applied to choose the most potential relay among K ones. Afterward, the instantaneous signal-to-noise ratio (SNR) differences between S-D, S-R and R-D channels are considered for adaptive selection between the direct and the cooperation transmission strategy. In the proposed adaptive protocol, if the direct link is of high quality, the source will transmit to destination directly with all power consumption. Otherwise, the source broadcasts the signal with a lower power and requires the help of the chosen relay if it decodes correctly, else the source will transmit again with remaining power. Firstly, the spectral efficiency is derived by calculating the probability of each mode. Subsequently, the BER performance for the adaptive cooperation scheme is analyzed by considering each event that one of K relays is selected and then making the summation of all. Finally, the numerical results are presented to confirm the performance enhancement offered by the proposed schemes.

As the open innovation paradigm spreads, the ability to search for new external knowledge and combine it with the organization's existing knowledge has been cosidered to play an important role in improving business performance of a company. This study empirically analyzed the influence of such organizational variables as empowering leadership, organizational learning culture, and interdepartmental cooperation on business performance of innovative technology SMEs focusing on the mediating effects of absorption capacity. For this purpose, a survey was conducted on 15,227 INNOBIZ SMEs, and 326 usable questionnaires were collected and analyzed using the structural equation model. Statistical analyses showed that the direct influence of empowering leadership, organizational learning culture, and interdepartmental cooperation on business performance was not found, but indirect effects of three organizational variables on business performance proved significant using absorption capacity as a mediating variable. This result also indicates that empowering leadership, organizational learning culture, and interdepartmental cooperation are important antecedent variables of absorption capacity.

We analyse the impact of R&D cooperation on Industrial R&D programs of Government (Ministry of Trade, Industry & Energy, MOTIE), specially performance differentiating between type of R&D partners, type of R&D project leader organizations. And considering five performance measures: paper, patent, technology transfer, commercialization, new employment. Using data on a large sample of post-performance survey of MOTIE in Korea (2013), we examine the impact of R&D cooperation in 2008-2012. The method of analysis is binary logistic regression models operated by SPSS. The results of this study are follows; the performance is statistically significantly different between type of R&D partners, type of R&D project leader organizations on R&D cooperation. Specially, when a private enterprise cooperate with non-profit institutions, performance has a greater success of paper, patent, new employment. On the other hand, when a private enterprise cooperate with a private enterprise cooperate, performance decrease success of paper, technology transfer. Lastly, when non-profit institutions cooperate with a private enterprise, performance has a greater success of patent, technology transfer.

Small- and medium-sized enterprises (SMEs) have strong incentives to engage in open innovation to enhance innovation efficiency and effectiveness due to their 'liability of smallness.' Previous research examined the performance effects of various open innovation practices, but whether coupled open innovation practices positively affect SMEs' firm performance is somewhat controversial. To resolve the issue, this study examined the effects of coupled open innovation activities on SMEs' firm performance using Heckman's two stage model to control endogeneity of the firms' self-selection bias in open innovation engagement. This study used the Korean Innovation Survey (KIS) 2020 collected by the Science and Technology Policy Institute (STEPI), and tested the effects of SMEs' coupled open innovation activities, R&D and non-R&D cooperation, on their innovative and financial performance indicators. The results showed that SMEs' R&D cooperation positively affects the new-to-market (NTM) product innovation only. Moreover, SMEs' non-R&D cooperation has positive effects on the product innovation, business process innovation, new-to-the-market product innovation, and new-to-firm (NTF) product innovation. However, the results showed that both R&D and non-R&D innovation cooperation activities have no significant effects on SMEs' financial performance indicators. This study contributes to research on SMEs' open innovation and provides insights for SMEs' managers and policymakers.

In this study, modal analysis and equivalent static load analysis for valve supports of 26" gas piping in gas stations were conducted and the existing straight and inclined types of valve supports were compared using seismic performance testing. Also, a new valve support shape was suggested by optimizing position of fastener holes, width and thickness of the support, and size of bracket. Improvement in seismic performance by design optimization was verified through equivalent static load analysis. The seismic performance of the newly proposed valve support was greatly improved and the maximum displacement and maximum stress of the seismic load was about 20% lower than those of the existing valve support.
