The steps related to the nutrient solution management were divided into 4 categories. The resistance for water movement in every steps was proposed. The priorities among the steps were set according to the cultural situation, which were used as the basis for the management in perlite bag culture. The enhancement of historical root development is especially critical, as well as how to supply essential water efficiently by minimizing the water movement distance to the root, which is the narrowest neck of a bottle in solution management.

To improve the cooperative efficiency of node cooperation and multiple access performance for multihop wireless networks, a priority-differentiated cooperative medium access control protocol with contention resolution (CRP-CMAC) is proposed. In the protocol, the helper selection process is divided into the priority differentiation phase and the contention resolution phase for the helpers with the same priority. A higher priority helper can choose an earlier minislot in the priority differentiation phase to send a busy tone. As a result, the protocol promptly selects all the highest priority helpers. The contention resolution phase of the same priority helpers consists of k round contention resolution procedures. The helpers that had sent the first busy tone and are now sending the longest busy tone can continue to the next round, and then the other helpers that sense the busy tone withdraw from the contention. Therefore, it can select the unique best helper from the highest priority helpers with high probability. A packet piggyback mechanism is also adopted to make the high data rate helper with packet to send transmit its data packets to its recipient without reservation. It can significantly decrease the reservation overhead and effectively improve the cooperation efficiency and channel utilization. Simulation results show that the maximum throughput of CRP-CMAC is 74%, 36.1% and 15% higher than those of the 802.11 DCF, CoopMACA and 2rcMAC protocols in a wireless local area network (WLAN) environment, and 82.6%, 37.6% and 46.3% higher in an ad hoc network environment, respectively.

Global attention to the greenhouse gas emissions from deforestation and forest degradation is increasing. There is a growing recognition of reducing emission from deforestation and forest degradation plus (REDD+) as an effective way to reduce greenhouse gas emissions in the forestry sector. The Republic of Korea is implementing REDD+ pilot projects in four Southeast Asian countries as part of its efforts to reduce greenhouse gas emissions. This study evaluates countries with the potential to become priority partner countries for Korea's REDD+ programs, using the following five criteria: The first criterion is that a country should include the forest sector and REDD+ in its national plan for reducing greenhouse gas (GHG) emissions. The second and third criteria refer to an average forest coverage rate of over 44% and a forest change rate of over - 0.1%, among the countries with forest cover of more than 10 million ha. The fourth criterion is that the country should meet the Forest Reference Emission Level requirements, one of the four elements of the Warsaw REDD+ Framework. The fifth criterion is that the country should have bilateral relations with the Republic of Korea in forestry while at the same time be a partner country for cooperation on climate change as well as a REDD+ pilot country. Based on our evaluation, we conclude that the first priority countries are Indonesia, Cambodia, and Myanmar. The second priority countries include Brazil, Ecuador, and Peru. Finally, the third priority countries are Columbia, Congo, and Mozambique. This study suggests that for the selection of priority partner countries, Korean REDD+ programs should center on existing REDD+ pilot countries.

The aim of this study was to investigate the priority partner countries for technical vocational education and training (TVET), using the cluster analysis. The partner countries were prioritized for finance supports and knowledge sharing. We had also redesigned the TVET assistance process as well as reflected the needs of recipient countries for TVET. Especially, by redesigning the methodological support process, we also increased the effectiveness and efficiency of TVET official development assistance. In research method, potential 24 priority partner countries have been designated by the international development cooperation committee and selection criteria of international cooperation agencies and banks. Then, we conducted the cluster analysis, using three main variables: economic factor, labor market factor, education factor. In results, we clustered four and three types of the priority partner countries for TVET. In future, we suggested the new approach for selecting the priority partner countries in terms of employment and labor as well as non-designated partner countries, which will need to cooperate for TVET.

The purpose of this paper is to examine the current status of the SW industry and technology in Korea and India, and to suggest future strategies for cooperation. To accomplish the goal, this study outlines the characteristics of the SW industry, its market size, and the current statuses of SW technologies in the two countries; and presents strategies for future cooperation by comparing the level of technology in the two countries while considering the need for vitalizing their cooperation. For comparing level of the SW industry's technology, so-called 4P evaluation (professionals, patents, papers, and products) was used, and a total of 21 projects were selected as future projects for cooperation through the analysis. In addition, the new approaches for future cooperation were presented; the exchange of manpower as a form of priority cooperation, more effort to develop and accumulate intellectual property rights to build conditions suitable for cooperation from India as well as a cooperation fund to bring continuous cooperation between the two countries.

Objectives: The purpose of this study is to draw priorities for candidate projects so that future inter-Korean traditional medicine cooperation can be promoted efficiently and effectively. Methods: This study used the Delphi-AHP method to derive priorities for the inter-Korean traditional medicine cooperation project. First, 33 candidate projects were selected through a data survey. In addition, the priority importance score was calculated through a 2-round mini-Delphi survey of 20 experts. The importance of 33 candidate projects was calculated by three evaluation criteria, and the weights for these three evaluation criteria were derived through the AHP method. Results: As for the weight by item, 'feasibility' was the highest with 0.6749 points, followed by 'social ripple effect' (0.1811) and 'instrumentality' (0.1439). As a result of calculating the importance score by reflecting the weight of the evaluation criteria for each project, the South's sole project, "Understanding the Status of North Korea's Korean Medicine," was the top priority, followed by the "Establishment of Strategy for Inter-Korean Traditional Medicine and Cooperation." Conclusions: As a result of this study, experts now believe that it is important to prioritize the highly feasible South Korean independent project in the field of traditional medicine between the two Koreas. This will serve as the basis for promoting cooperative projects in the event of future changes in the inter-Korean situation.

This study tried to suggest South-North Korea's S&T cooperative strategies and priority areas using mixed-methodology. First, survey research was conducted to analyze the understanding of scientists how they think about these issues. We surveyed scientists whose names are on the KOFST mailing list and analyzed 485 questionnaire responses. After that, experts who are participating in FGI discussed more deeply about the survey results and suggested the feasible strategies and projects. The results suggest some findings about priority cooperation area, new projects and strategies. Priority areas of S&T cooperation are following; agriculture, electricity & energy, and health care. However, more important thing than these priority areas is how to approach the inter-Korean S&T cooperation. More strategic approach is needed while promoting exchange and cooperation projects with north-korea. Also more long-term approach is needed to maintain the sustainability of this S&T cooperation.
