With the recent slowdown of R&D budget growth rate, efficient resource allocation, operation and management of national R&D is becoming more important. At this point, recognizing the necessity of systematic and scientific research on the national R&D itself, this study analyzed previous researches on national R&D of Korea. In this study, based on the previous researches and laws, national R&D was classified according to the major stages such as planning, selection, management, performance and so on. Secondly, by using the classification criteria forged, previous researches on the national R&D published in domestic journals for the last 5 years were divided into 12 categories, and the status of researches in each field was analyzed. Lastly, through network analysis, linking status and influence of each fields were identified by using co-classification information of research literatures. As a result of this research, the performance related fields were the most active ones in terms of the number of research literatures, and connections with other fields, while the fields such as selection and infrastructure were lacking in the number of research and linkage. This study can find its meaning in identifying research fields that need more studies and connections with other areas by systematic analysis of previous studies on Korean National R&D.

A multiple-trait stochastic computer simulation model was constructed to predict the breeding schemes and selection methods on Hanwoo(Korean cattle). The model could be used four kinds of selection criteria (random, phenotype and true or estimated breeding values). At the test run in various population size for 20 years, all estimated parameters of the each simulated populations were resulted similar to input parameters. The deviations between input and output values of parameter in the large population were smaller than in the small population. The simulated results obtained from ten small populations consisted with one sire and ten dams in each population for 500 years were as follows; Inbreeding coefficients of population were similar to theoretical estimating function. Mean values of each traits selected were randomly drifted by generation, but they were converged into a value when inbreeding coefficients came close to one. Additive genetic variances within each population were reduced by generation, and they were converged into zero when inbreeding coefficients came close to one. These results indicated that the simulated populations hold to statistical properties of input parameters.

The importance of international science and technology cooperation is growing more and more, but we do not know much about what criteria could be used to choose a science or a technology that needs international cooperation first and foremost among many kinds of competing sciences and technologies. Moreover, this selection process is affected by evaluators' or science/technology experts' perception, but we do not quite know what they actually see when they evaluate the needs of international cooperation. This study investigates the conditions that international science and technology cooperation is encouraged by scholars and researchers in various areas. Based on theoretical arguments of Transaction Cost Economics, Measurement View, and Knowledge-Based View, we drew hypotheses on when experts perceive greater needs of international cooperation. Using the classification categories of 10 major sciences and technologies, we collected data from 151 respondents from scientists in research institutions and colleges. As a result, we found that experts in science and technology areas perceive strong needs of international cooperation when the importance of focal science or technology is high and the relative national level of focal science or technology is low. Also, we found that the importance and relative level of focal science and technology have positive moderating effects each other. Lastly, we found that when experts evaluate their own major areas, the strength of positive relationship between the importance of science and technology and needs of international cooperation is diminished.

While deforestation and forest degradation has continued globally, global society has been making efforts to prevent deforestation towards sustainable development. Reforestation in developing countries is linked to Sustainable Development Goals (SDGs) such as climate change mitigation, conservation of biodiversity, eradication of poverty and upholding of human rights. Forest official development assistance (ODA) restores the global forest land, and increases the public benefit. Bilateral forest ODA projects of the Republic of Korea have gradually increased and most of those projects have currently been concentrated in Asian countries. Selecting recipient countries for forest ODA requires more comprehensive approach since the global goals for sustainable development has been widely adapted to ODA strategic plans. We proposed potentially promising countries that are eligible for receiving 'Green ODA' in perspective of economic, social and environment to implement reducing emissions from deforestation and degradation (REDD+), conserving biodiversity, and combating desertification. As a result, the study suggests that forestry cooperation could be expanded from Asian countries more toward South America and African countries. In addition, we emphasized the need to promote convergence and integration with green technology to fundamentally solve the negative impacts of deforestation such as food, energy, water resource shortages, and forest fires. We advocated expanding bilateral ODA in the forestry sector through diversification of project activities, financial sources, and participants. Our study can contribute to the provision of basic information for establishing long-term strategies to expand bilateral cooperation in the forestry sector.

Purpose: This review is to figure out evidence that suggest effectiveness of Korean Medicine treatments against cervical dysplasia. Methods: Studies on cervical cancer and cervical dysplasia were searched through 6 databases: Korean Studies Information Service System(KISS), National Discovery for Science Leaders (NDSL), Korea Institute of Science and Technology Information (Korean TK), Oriental Medicine Advanced Searching Integrated System (OASIS), the Journal of Korean Medicine, and the Journal of Korean Obstetrics & Gynecology. After that, the articles were extracted with reference point of Korean Traditional Medicine. Results: 37 articles were included lastly according to selection criteria. 3 of them were case reports on cervical dysplasia, and 34 were in-vitro studies on Human Papilloma Virus (HPV) positive cancer cell. In case reports, acupuncture, moxibustion, medical herbs and pharmacoacupuncture were used for treatments of cervical dysplasia with about 3 months. Experimental studies on cervical cancer cell showed that several herbs function with clear heat, eliminate stasis (淸熱解毒, 化瘀消腫) have anti-cancer effects inducing apoptosis. Conclusions: The results of articles are not enough to use in practice. Therefore, we indicates more advanced research methodology as follows: development of Korean Medicine treatment protocol with oral and external, in-vivo experimental study, and evaluation immunity index.

PURPOSES: The purpose of this study is to develop a methodology to prioritize sidewalk construction on rural national highways. METHODS : In order to determine an appropriate prioritization for sidewalk construction, we developed a specific methodology. The proposed methodology includes three main steps: 1) Analytic Hierarchy Process (AHP) methods, 2) Subjective evaluation of relevant road agencies for the candidate sidewalks along rural national highways, and 3) Field study conduction. Each step has four phases. The primary feature of this methodology is the addition of expert consultation and survey data, as well as a field study. In addition, the method could guarantee flexibility in selection for evaluation criteria. As a result, the proposed methodology could be used as a general procedure for application to other roadway classifications when considering sidewalk construction. RESULTS: In order to demonstrate the reasonableness of the proposed methodology, a case study was performed for exactly 100 candidate sites for sidewalk construction on rural national highways. All required evaluation scores were properly produced for each candidate site. By doing so, decision-makers can determine the priority for sidewalk construction at these sites by reviewing quantitatively and qualitatively considered data. CONCLUSIONS: The results of the case study can be applied to a long-term fundamental plan for sidewalk construction on rural national highways. Furthermore, this methodology could be employed to prioritize a small-scale SOC project(e. g. bicycle or pedestrian roads).

Mold industry has the difficulty to employ young people as the successors of the skilled workers, because it has been regarded as a 3D-jobs(dirty, difficult, and dangerous). To overcome this situation, thus, manufacturing technologies maintained in the factory should be systemized, and engineering systems should support unskilled workers to do their jobs without any difficulty. As a research of developing the supporting system, this study proposes a decision support system that facilitates unskilled workers to easily select high quality NC-data, as well as to increase productivity. The proposed system is assumed to follow a CAM operation scenario that consists of next three steps: 1) identifying several process plans and enumerating feasible unit machining operations (UMOs) from material and part surface information, 2) creating all feasible NC-data based on UMOs using a commercial CAM system, 3) selecting the best NC data among the feasible NC data using four screening criteria, such as machining accuracy, machining allowance, cutting load, and processing time. A case study on the machining of a camera core mold is provided to demonstrate the proposed system.

This paper suggests facility planning ideas for recreational fishing complexes suitable for family anglers. Existing recreational fishing parks are only equipped with facilities for angling. There are many needs for recreational fishing complexes in coastal fishing villages that include not only angling facilities but also various marine leisure and sports facilities. In this paper we suggest concepts for recreational fishing complexes and define four types of complexes in terms of facilities planning. These four types of complexes are: 1) suburban leisure sports, 2) suburban healing and relaxation, 3) penturban experience and activities, and 4) penturban culture and recreation. Then we propose facility composition in detail for each type. Also we suggest site selection criteria for the village complex, facility infrastructure planning ideas, and leisure facilities (elementary and specialized) for recreational fishing complexes.

Researchers have suggested successful risk management as a key factor in successful IT outsourcing projects implementation. The documented investigations, however, have mainly addressed risk management only from a single perspective of either clients or IT vendors. This study explored the potential perception inconsistency regarding the risks between the client and the vendor for IT outsourcing projects by using a quasi-Delphi approach. The analysis results indicated some inconsistencies in the risks perceived by the two parties: (1) the clients regarded (a) lack of vendor commitment to the project and (b) poor vendor selection criteria and process as top critical risks but the vendors didn't; and (2) on the other hand, the vendors perceived (a) unclear requirements and (b) lack of experience and expertise with project activities as significant risks but the clients didn't. Insights into how the client and the vendor perceive risks may help both parties determine how to partner and manage project risks collaboratively to succeed in outsourcing.
