본 연구는 두만강 유역국가(북한, 중국, 러시아) 및 인접국가(한국, 몽골, 일본) 간의 협력과정과 현안을 1991년부터 현재까지 광역두만강개발계획(Greater Tumen Initiative: GTI)을 통해 검토함으로써 동아시아에서 지역개발계획을 통한 공동의 이익창출과 공유가능성을 짚어보고 정책적 시사점을 찾고자 한다. 분석이론으로 이익공유(Benefit Sharing)이론을 적용하여 국제하천에서 한 유역국가가 독단적인 계획과 사업을 통하여 얻는 이익보다 모든 유역국가의 참여를 바탕으로 추진하는 지역개발을 통한 이익이 더 크다는 점을 확인하고자 한다. 두만강 유역은 1991년 UNDP 주도 하에 두만강지역개발프로그램(Tumen River Area Development Program: TRADP)을 시작으로 지역개발협력이 진행되어 2005년 광역두만강개발계획으로 발전되었으나 2009년 북한의 GTI 탈퇴, 리더쉽 부재, 재원부족 등으로 현재 답보 상태에 빠져있는 실정이다. 그럼에도 불구하고 프로그램 진행 과정 속에서 회원국 간의 공통 관심사항을 도출하고 직간접적으로 동아시아 평화안보 구축에 도움을 주었으며 교통, 물류, 에너지, 관광 및 환경 관련 사업을 추진하여 동아시아 공동 지역개발의 단초를 마련하는 성과를 거두었다. 아직 풀어가야 할 숙제가 많지만 GTI는 2014년 이후 본격으로 추진하고 있는 국제기구로의 전환을 통해 새로운 전기를 마련하고자 노력하고 있다. 또한 GTI는 북한 핵무기 개발과 미사일 발사 등으로 경직되어있는 동북아 상황을 완화하고 현 정부의 신북방정책의 발전을 위한 교두보 역할을 할 수 있을 것이며 역내 국가 간 협력을 지속적으로 추진할 수 있는 밑바탕이 될 수 있을 것이다.

해양사고는 도로교통과 달리 지속적으로 증가하고 있으며, 인명피해가 주로 발생하는 주요 사고의 치사율은 도로교통의 11.7배 이상이다. 해양사고는 외부 환경에 따라 사고 위치가 변하고 즉각적인 조치가 어려워 타 교통에 비해 대형 사고로 이어질 가능성이 매우 크다. 그러나 여전히 사고가 발생하고 난 후 대응하는 등 사후적 관리 단계에 무르고 있어 사고의 주요 요인을 사전에 식별·관리하는 선제적 관리단계로의 전환 필요성이 대두되고 있다. 따라서 본 연구에서는 해양사고 발생 지점 밀도 기반의 가변 공간 군집체계를 반영한 해양사고 예측모델을 개발하였다. 반복적인 공간 가산분석을 통해 밀도가 높을수록 작은 규모의 격자 체계를 가질 수 있도록 상세한 공간 군집체계를 구성하였으며, 단순 사고 위험도 예측뿐만 아닌 사고 인과관계를 설명할 수 있는 BN(Bayesian Network) 기반의 모형을 사용하여 해양사고 위험예측 모델을 개발하였다. 또한, Cost-of-Omission을 통해 해양사고 예측확률의 변화와 각 변수들의 영향력을 확인하였으며, 월별 해양사고예측 결과를 GIS를 활용하여 2D/3D 기반으로 시각화하였다.

Bioconversion and fermentation of onion extract by lactic acid bacteria were carried out to enhance the bioavailability of quercetin through the increase of quercetin recovery and aglycone formation. Lactobacillus casei, L. plantarum, and Kluyveromyces lactis were selected as the optimum strains for bioconversion. The environmental conditions to maximize the conversion ratio between glycoconjugate and quercetin aglycone have been evaluated. The concentrations of quercetin after fermentation of onion slurry by K. lactis and L. casei increased to 260% and 318%, respectively; however, the quercetin concentrations decreased after 48 hours of fermentation. Additionally, the quercetin hexose concentration increased to almost 141%. Controlling the initial pH of the onion juice increased the lactic acid production by L. casei and L. plantarum by more than two-fold. Meanwhile, the concentration of quercetin hexose decreased rapidly with the increased production of aglycones. The scale-up experiments showed the same fermentation efficiency; however, thermal sterilization reduced the quercetin glycone concentrations drastically.

China has transformed her strategies for economic development from exogenous development founded on foreign capitals to endogenous development based on enhancing technology innovation capabilities since 2000. More specifically, Chinese business activities have coupled with new institutional settings which enable them to facilitate advanced technology and management methods. As a result, the characteristics of the spatial economy in China are likely to transfer from export-led developmental space to technology-oriented developmental space. In this context, this paper aims to identify the characteristics of technology-oriented space by investigating intra-, inter- and extra-firms relations of Korean FDI firms in Shanghai, China. In terms of intra-firm relations, Korean FDI firms adopted strategies for maximizing business efficiency and effectiveness by transforming their personal networks into formal networks. In terms of inter-firm relations, the distinction of Korean FDI firms' networks has been found in accordance with firm size, industrial sectors, ways of investment etc. Finally, Korean FDI firms has formal networks resulted from institutional involvement, as well as informal (personal) networks based on guanxi (inter-personal relations) in extra-firm relations. Therefore, two types of processes affecting the networks and institutional legacies of the Soviet system can be identified. First is the interaction of institutions and restructuring of pre-existing networks. Second is the insulated institutions and endurance of preexisting networks. And these two governance types have created regional economies which are embedded and over-embedded.

Magnetic materials has been applied to various fields due to their energy convertible properties between electrical and mechanical energy. Particularly, permanent magnets have been currently attracted much attention because they produce external magnetic field without any electrical current. For high efficiency, a demand for permanent magnets containing rare earth elements has been continuously increased, which abruptly raises the price and causes the supply difficulty of rare earth materials. Therefore, the development of permanent magnets with less or without rare earth elements become a urgent issue. In this report, the current trend and major issues on high efficiency permanent magnets, particularly exchange-coupling magnets, are discussed.

With the low birth rate and the inner city decline, the number of small schools is expected to increase. In this trend, the Ministry of Education has consistently used the number of students as a standard for the merger and abolition of schools since 1982, but it seems that has generated a vicious circle of education in rural areas and also it did not reflect realistic requirements and changes in the times although it is efficiency of local education finances. With the number of students constantly decreasing, it has a high probability to make villages without schools in urban areas if decisions are made by the number of students. In this sense, it is suggested that regional contexts and socioeconomic environment should be taken into account rather than to conduct the merger and abolition of small schools with economic logic. It is necessary to change the direction of improving the quality of education through the operation of small schools for coexistence of schools and villages and a cultivating the manpower needed in the 21st century knowledge information society and the 4th industrial revolution era. Therefore, we tried to find tasks for expanding small schools of the local community and developing small schools suitable for future social change.

In the trend of digital transformation and the increase in non-face-to-face services triggered by the Fourth Industrial Revolution, the demand for cloud computing services is being sharply stimulated. Currently, the cloud is being introduced in various industrial sectors including public, IT, and finance, and the manufacturing industry is also adopting the cloud to secure future sustainability and is promoting innovation through smart manufacturing. However, it has been found that there are constraints in the adoption of cloud by manufacturing companies due to concerns about security. Existing studies that have identified cloud security risks have been limited to presenting general cloud security risks or technical security risks rather than focusing on the manufacturing industry. Therefore, this study aimed to identify cloud security risks in the manufacturing industry based on the actual concerns in the field. For this, expert interviews and literature research were conducted to newly identify cloud security risks in the manufacturing industry, and the adequacy and urgency of the selected security risks were verified through surveys. Based on this study, if a cloud security management system for the manufacturing industry is designed in the future, it is expected that the adoption of cloud in the manufacturing industry will be more activated.

This study explored the development and applicability of a classics book reading program in the nursing curriculum as a character education program in order to enhance nursing students' holistic growth and development. An increasing number of universities in Seoul have introduced a classics book reading program as part of the curriculum and some have even designated it as an essential subject. Various such programs have been developed in addition to the regular education curriculum. The following aspects are important to consider in a classics book reading program for nursing students: trust, respect, responsibility, fairness, caring, citizenship, endurance, healthy self-concept, and self-sustained growth performance. Classics book selections need to take into account the level of the students, and the efforts should be made to ensure the accuracy of the translation and the level of students' understanding. It is difficult to form character through short-term education. Despite difficulties, character formation requires continued interest and systemic education that will lead nursing students to show inbuilt positive characteristics. Inclusion of character education in the nursing curriculum should be considered with the agreement of the university, based on political decision-making.
