In this study, the factors affecting the efficiency of 48 projects of private R&D institutes were analyzed using the Tobit model. Influencing factors were selected as open R&D network size, IT industry, interaction between R&D network size and IT industry, and type of R&D network cooperation. As a result of Tobit analysis, the R&D network size, the IT industry, and the type of R&D network cooperation were found to be significant. The larger the open R&D network size, the lower the efficiency, and the IT industry showed lower R&D efficiency than other industries. In addition, cooperation with universities and research institutes showed lower R&D efficiency than cooperation with companies. As a result of these studies, companies will be able to select and focus on cooperation with the outside in relations and investment allocation.

The purpose of this study was to identify obstacles by surveying dieticians' perception in implementing Generic HACCP Plan for school foodservice operations from 2001. The survey was conducted in five areas; Seoul, Kyoung-gi Province, In-cheon, Kwang-ju and Dae-jeon. Five hundred and sixty questionnaire were sent by the e-mail address and the local school dietician's Community Board on the internet, 263 were returned. Two hundred and forty were returned by E-mail, return rate was 42.86%. Twenty three were received by the local school dietician's Community Board on the internet. The obstacles were grouped of six fields and indicated thirteen factors in implementation of the Generic HACCP Plan for school foodservice. The six fields were 'status of cooperation within HACCP team', 'cooperation with the external people' such as teachers, food suppliers, student's parents, 'understanding HACCP system of the dieticians', 'hygiene facilities', 'training & educating employees', and 'difficulty of monitoring'. To assess the factor as a obstacle we used Likert's scale; 5-agree strongly, 4-agree, 3-medial, 2-don't agree, 1-don't agree strongly. Results of this study are as follows; 1) The scores of thirteen factors indicated as obstacles were over 3(medial) except ‘lack of dietician's understanding about HACCP System(2.86$\pm$0.97)'. Also only about 63% dieticians recognized that as an obstacle factor. 2) ‘Deficiency of hygiene facilities(4.41$\pm$0.76), ‘lack of teachers' cooperation(4.23$\pm$0.77)', ‘inadequacy of the kitchen lay-out(4.19$\pm$0.95)' and ‘lack of training and educating program for employees(3.97$\pm$0.85)' scored most highly. Results from this study show that financial resources and educating system are very important to settle down HACCP system for School Foodservices successfully.

This study investigated librarians' perception and preference of cultural programs in the field of cooperation between school and public libraries. The findings are as follows: 1) Librarians and teacher librarians at school and public libraries perceive the importance of cultural programs in library service. 2) Online space was mostly preferred as a means of PR activities by librarians and teacher librarians at school and public libraries. 3) The preferred methods to cooperate projects between school libraries and public libraries were to implement programs through public librarians' field visiting, and to participate linkage program customized to individual school libraries. 4) Preferred types of cooperation were to sign MOU and to make a cooperative system between school libraries and public libraries.

Supply chain management for complex project requires continuous integration activities with the suppliers and subcontractors. This study proposes the firm performances, trust, relational norms, interfirm conflict and cooperation as major research variables, and collected the survey responses from the suppliers and subcontractors having experiences with complex projects. The statistical results indicate that the cooperation and conflict influence the firm performances, and that the inter-firm trust have some impact on the level of cooperation and conflict. It was also found that the inter-firm cooperation is influenced by relational norm. But on the contrary to our expectation, the relational norm has no significant impact on the inter-firm conflict. These findings may offer the significant implications leading to successful implementation of collaborative supply chain management in the context of project engineering area.

The political conflicts and military collisions between the South-North Korea resulted in actions taken at 1 of Dec. in 2008 and 24 May in 2010. Those actions stopped the major economic cooperations such as the relink of a railroad line across the divided peninsula as well as Mt. Geumgang tourist trade, and cast shade on the Gaesung Industrial Complex. This article articulates the current situation of the economic damages, status quo of cooperation and the South Koreans' changed way of thinking about issues between the South and North which provoked by the conflicts. We emphasized the necessities of minimizing unstable non-economic factors on the Peninsula; continuing win-win economic cooperation between the South-and North corporations; guaranteeing safe business conditions; improving the relationship based on the national consensus. Also we suggested ideas on how to manage the economic cooperation and how to explore new business opportunities in the future based on entrepreneurial leadership.

In this paper we are investigating how ubiquitous revolution in knowledge society changes the education system. By the help of ubiquitous computing and networking techniques we estimates the configuration of e-teaming in the age of knowledge -based society, and we examines Education Model with e-teaming and ICT (Information and Communication Technology) at e-School. We also suggest the feasible design of the e-School and a Blended-learning scheme based on cooperative education as a way of teaching Education.

We consider a two-hop multiple-relay network implemented with opportunistic decode-and-forward cooperative strategy, where the first hop and second hop links experience different fading (Rayleigh and Rician). We derive the exact expressions of end-to-end outage probability and analyze the approximate results in high signal-to-noise ratio region. The analysis shows that the same diversity order can be achieved even in different mixed fading environments. Simulation results are provided to verify our analysis.

In the present study, long-term heavy metals (HMs) contaminated soil samples from a well-known Pb/Zn smelting area in the southwest of China were collected, and physicochemical and biological characteristics of these samples were evaluated. Soil samples contained different concentrations of HMs, namely Pb, Zn, Cu, and Cd. Enzyme activity analyses combined with microcalorimetric analysis were used for soil microbial activity evaluation. Results showed that two soil samples, containing almost the highest concentrations of HMs, also shared the greatest microbial activities. Based on correlation coefficient analysis, high microbial activity in heavily HMs contaminated soil might be due to the high contents of soil organic matter and available phosphorus in these samples. High-throughput sequencing technique was used for microbial community structure analysis. High abundance of genera Sphingomonas and Thiobacillus were also observed in these two heavily contaminated soils, suggesting that bacteria belonging to these two genera might be further isolated from these contaminated soils and applied for future studies of HMs remediation. Results of present study would contribute to the evaluation of microbial communities and isolation of microbial resources to remediate HMs pollution.
