This study seeks to analyze trends in Korean government support for marine biotechnology R&D investment. The quantitative analysis proposed in this paper provides useful data to inform government policy making decisions in relation to R&D investment in the marine biotechnology. Data used in this study is from NTIS (National Science & Technology Information Service) DB. Empirical results indicate that national R&D investment in the area of marine biotechnology has recently been increased in terms of the number of R&D programs and the amount of R&D investment. The results also show that the R&D programs in the area of marine biotechnology involve various Ministries of the government of Korea, although the Ministry of Oceans and Fisheries (MOF) performed a key role in the R&D investment in the marine biotechnology. Finally, the results of social network analysis in this study reveals that most of the R&D programs in the area of marine biotechnology seeks the development of new materials using unique features of marine bioresources.

대표적인 상용 CFD 코드 중 하나인 FLOW-$3D^{(R)}$에 포함된 강체에 대한 6-자유도 운동을 적용한 음해법의 GMO 방법을 이용하여 항주파의 재현 가능성을 살펴보았다. 모델에 의한 항주파의 형상 재현시 depth Froude number에 따른 수평 파형이 잘 재현되었으며, 선박의 직선항로 항행시 일정한 수심인 경우와 실제 수심인 경우를 비교함으로써 모델이 수심에 따른 파형의 변화를 잘 재현함을 알 수 있었다. 또한, 모델에 의해 실제 수심조건에서 두 척의 선박이 교차 진행할 경우와 선박이 곡선항로를 항행할 경우에 대한 항주파를 잘 재현할 수 있음을 보였다. 따라서, FLOW-$3D^{(R)}$를 이용하여 항주파를 수치모의할 경우 관측을 통한 모델의 검 보정을 통해 항로와 항구에서의 항주파를 보다 정확하게 예측할 수 있을 것으로 판단된다.

The purpose of this study is to demonstrate, through case studies, the usefulness of utilizing local R&D centers under science and technology ODA programs. For the past few decades, advanced countries have supported ODA projects of developing countries, but there have been negative opinions regarding the results. Through a case study of the black pearl cultivation project between the Korea Institute of Ocean Science & Technology and Micronesia, this study explains the usefulness of actively utilizing Korean R&D centers established and operational in recipient countries. Although black pearl cultivation is not an ODA project, the case study offers valuable insights as it is operated in a similar form and thus highly applicable to future projects. Based on the case study, four implications were derived to ensure the successful operations of science and technology ODA projects in the future. First, there is a need to improve relevance by making use of the technological capacities of local R&D institutes to develop projects that reflect the needs of recipient and donor countries. Second, trust must be established with local communities over the long term in order to enhance the effectiveness and efficiency of project operations. Third, the proportion of science and technology ODA projects must be expanded to acquire sustainability, and more support should be granted to ODA projects involving marine resources, which are an advantage for countries of Micronesia. Lastly, the locals should be offered employment opportunities and regular training programs to allow for the actual transfer of knowledge instead of mere techniques. The implications derived in this study will prove useful in pursuing science and technology ODA projects, especially with Micronesia.

This study examined how national research and development (R&D) in the domain of logistics has changed recently in the Republic of Korea. We conducted basic statistical analysis and social network analysis on 5,327 logistics-related R&D projects undertaken during 2005-2019. Data for performing these analyses were collected from the R&D database of the National Science and Technology Information Service (NTIS). By constructing a co-occurrence matrix with keywords, we conducted degree and betweenness centrality analysis and visualized the network matrix to display a cluster map. This study presents our observations related to the following findings: (1) the chronical trends of logistics R&D, (2) focused fields of logistics R&D, (3) the relations among keywords, and (4) the characteristics of logistics R&D. Finally, we suggest policy implications to boost and diversify logistics R&D.

The development of manganese nodule mining technology is very important in order to secure a long-term and stable supply of rare strategic metals. In the twenty years following the R&D activities with the international consortia in the 1970s, studies on mining technologies have been carried out by several national projects in Korea. The current metal prices such as copper, nickel, cobalt, and manganese have been drastically changed since 2002. Rapid economic growth of Asian countries, especially China, have induced the situation. And the possibility of copper shortage is looming just around the comer. Because of the imbalance between production and consumption, copper is fundamentally the most threatened metal in the future in terms of potential metal shortage. Manganese nodules contain a considerable percentage of copper as the future metal resource. Therefore, it is necessary to concentrate our effects on developing these resources. This paper introduces our evaluation of R&D progress for the development of manganese nodules. The issue and role of manganese nodules during the difficult period of a potential future metal shortage period is discussed and its prospect outlined. Also, this paper tried to emphasize the necessity of continuous R&D efforts for the commercial development of such mineral resources.

포항신항이 단계별로 완공된 후 제기되어 온 항내정온도 불량 문제는 항만가동율 저하의 주요 원인으로 제기되어 왔으며 이의 개선을 위해 2018~2020년 포항신항 외항방파제의 외해 측에 도제(Detached breakwater)를 건설하고 있다. 본 연구에서는 도제의 효과를 검증하기 위하여 도제 설치 전후로 취득된 항내외의 파랑 관측자료를 분석하여 항내에서의 파고감소율을 비교한 결과를 제시한다. 먼저 이전 수치모델 연구를 통해 예측된 파고는 항내 4개 지점 중 3개 지점에서 관측값과 비슷하게 나타났으며 나머지 1개 지점에서의 오차는 수치모델이 부두 안쪽에 발생하는 중복파 현상을 잘 재현하지 못했기 때문으로 판단된다. 도제 건설 전후 기간의 관측값을 비교한 결과 도제 설치가 항내정온도 개선에 기여한 것으로 나타났는데, 항내 4개 관측지점 모두에서 포항신항 정온 목표파고인 0.3 m를 초과하는 파고의 출현빈도가 도제 건설 후에 크게 감소하였다. 또한 항내외 파고를 비교한 항내 파고 감소율도 모든 파향에 대해 도제 건설 후에 유의미하게 개선된 것으로 나타났다. 본 연구결과는 적절하게 설치된 연안구조물이 항내정온도 향상에 기여하는 효과를 증명한 것으로 향후 유사한 경우의 문제 해결에 유용하게 적용될 수 있음을 보여준다.

The marine biotechnology industry is very significant as compared to other industries as one of the driving forces for economic growth in the next generation in Korea. However, the marine biotechnology market has been considered as a component of the biotechnology industry market which made difficult for creating separate research areas in relation to the scope of the relevant industry market as well as making it difficult to establish its own R&D policy strategies. Accordingly, this study was executed to estimate the future long-term market value of the marine biotechnology within the limit of industrial field and to verify the importance of national R&D investment in marine biotechnology on the basis of estimations within the industrial perspective. To this end, we classified the marine biotechnology industry into the four sub-sectors and estimated the domestic and global industrial market in 2010 and 2024. According to the results, the domestic and global market of the marine biotechnology industry will see a remarkable growth by 2024. In particular, the bio-energy, pharmaceutical and functional foods industry markets will achieve astonishing advances. On the basis of the analysis results, Korea has to establish more progressive and aggressive R&D investment strategies to strengthen national competitiveness through the marine biotechnology industry.
