China's new Maritime Policy Law (MPL) purports to regulate the duties of China's maritime police agencies, including the China Coast Guard, and safeguard China's sovereignty, security, and rights and interest. The MPL has potentially far-reaching application, as China claims extensive maritime areas off its mainland and in the South China Sea. This expansive application of maritime law enforcement jurisdiction is problematic given that most of China's maritime claims are inconsistent with international law. To the extent that the MPL purports to assert jurisdiction over foreign flagged vessels in disputed areas or on the high seas, it contravenes international law. Numerous provisions of the MPL regarding the use of force are also inconsistent with international rules and standards governing the use of maritime law enforcement jurisdiction, as well as the UN Charter's prohibition on the threat or use of force against the territorial integrity or political independence of any state. China could use the MPL as a subterfuge to advance its illegal territorial and maritime claims in the South and East China Seas and interfere with coastal State resource rights in their respective exclusive economic zone.

This paper explores the limited role of alliances in preventing maritime territorial disputes among member states, using the ongoing conflict between Greece and Türkiye, two NATO allies, as a case study. Drawing on Institutionalist theory, we seek to explain the mechanisms that have contributed to the failure of the alliance to prevent this dispute, despite constant cooperation and transparency. Unlike land disputes, maritime territorial disputes are complex and multi-layered, with fluid boundaries that can change with climate or natural resource availability. Moreover, the lack of constant surveillance creates ambiguity about territorial encroachment thresholds. These factors have exacerbated the dispute between Greece and Türkiye, drawing other NATO members into the conflict and undermining the strength of the alliance. This paper concludes by providing policy implications for the Republic of Korea in its own potential maritime disputes, and contributes to the broader literature on the role of alliances in preventing territorial disputes.

The paradigm of warfare is undergoing a revolutionary transformation due to the advancements in technology brought forth by the Fourth Industrial Revolution. Specifically, the U.S. military has introduced the concept of mosaic warfare as a means of military innovation, aiming to integrate diverse resources and capabilities, including various weapons, platforms, information systems, and artificial intelligence. This integration enhances the ability to conduct agile operations and respond effectively to dynamic situations. The incorporation of mosaic warfare could facilitate efficient and rapid command and control by integrating AI staff with human commanders. Ukrainian military operations have already employed mosaic warfare in response to Russian aggression. This paper focuses on the mosaic war fare concept, which is being proposed as a model for future warfare, and suggests the strategy for introducing the Korean mosaic warfare concept in light of the changing battlefield paradigm.

국가 에너지원의 다원화와 환경공해 저감은 정부의 저탄소 녹색성장 정책과 에너지 안보를 위해 달성해야만 하는 필수불가결한 과제로 자리 매김한지 오래이다. 또한, 화석연료의 환경문제 유발과 석유자원의 고갈위기 등으로 인해 이를 대체할 수 있는 신재생에너지 개발에 대한 관심이 고조되고 있으며 이러한 과제를 해결하기 위한 친환경 연료로써 DME(Dimethyl ether)에 대한 관심이 날로 증가하고 있는 추세이다. 특히 높은 세탄가를 지니고 물성이 LPG와 유사하여 디젤차량 및 LPG 대체 연료, 연료전지 등의 다양한 용도로 사용할 수 있고 수송 저장 수단, 인프라 구축 등의 장애가 적다는 장점이 있으며, LPG와 물리적 특성이 비슷해 기존 LPG 인프라를 개조하지 않고도 LPG와 혼합해 난방 및 취사뿐 아니라 차량 연료용으로도 시범사업이 활발히 추진되고 있는 상황이다. 그밖에도 액화상태로 저장 운송 등의 취급이 용이하다는 장점이 있다. 한국가스공사의 경제성 분석 결과, 본격 보급시 LPG대비 20~30% 저렴하게 공급가능하다고 판단되어짐에 따라 LPG사용자 부담을 완화할 수 있는 기대를 가지게 한다. 이에 우리협회는 지경부 한국가스공사등과 함께 프로판에 DME가 20%의 혼합된 DME혼합연료 소비자에게 보급하는 시범사업을 전개하고 있으며 현재까지 진행된 내용과 향후 계획등을 소개함으로써 DME에 대한 이해를 높이고자 한다.

In order to survive the on-going natural resource war, Korea needs various efforts such as enhancing self-exploitation ratio, increasing the supply of new-reuse energy, strengthening cooperation with resource rich countries. Central Asian countries are geometrically far away from Korea. However, Korea should try to develop political, economic and ethnic relationship with those countries into much higher dimension to secure various natural resources. Major countries including U.S., EU. Japan and China are approaching Central Asian countries with long term perspective. Improving country-image through enlargement of ODA is the first concern of those countries. Korea should try to follow their practices. Government should try to improve Korea's image in the first place and lead economic cooperation with very detailed supportive measures to induce Korean firms' investment into the Central Asian countries. In the due process, a lot of information about those countries' political climate, social situation, ethnical composition, major religions, educational system, current state and structure of economies and industries, etc should be made available to Korean firms.

The Global Framework on Climate Services (GFCS) will guide the development of climate services that link science-based climate information and predictions with climate-risk management and adaptation to climate change. GFCS structure is made up of 5 pillars; Observations/Monitoring (OBS), Research/ Modeling/ Prediction (RES), Climate Services Information System (CSIS) and User Interface Platform (UIP) which are all supplemented with Capacity Development (CD). Corresponding to each GFCS pillar, the Commission for Agricultural Meteorology (CAgM) has been proposing "Global Initiatives in AgroMeteorology" (GIAM) in order to facilitate GFCS implementation scheme from the perspective of AgroMeteorology - Global AgroMeteorological Outlook System (GAMOS) for OBS, Global AgroMeteorological Pilot Projects (GAMPP) for RES, Global Federation of AgroMeteorological Society (GFAMS) for UIP/RES, WAMIS next phase for CSIS/UIP, and Global Centers of Research and Excellence in AgroMeteorology (GCREAM) for CD, through which next generation experts will be brought up as virtuous cycle for human resource procurements. The World AgroMeteorological Information Service (WAMIS) is a dedicated web server in which agrometeorological bulletins and advisories from members are placed. CAgM is about to extend its service into a Grid portal to share computer resources, information and human resources with user communities as a part of GFCS. To facilitate ICT resources sharing, a specialized or dedicated Data Center or Production Center (DCPC) of WMO Information System for WAMIS is under implementation by Korea Meteorological Administration. CAgM will provide land surface information to support LDAS (Land Data Assimilation System) of next generation Earth System as an information provider. The International Society for Agricultural Meteorology (INSAM) is an Internet market place for agrometeorologists. In an effort to strengthen INSAM as UIP for research community in AgroMeteorology, it was proposed by CAgM to establish Global Federation of AgroMeteorological Society (GFAMS). CAgM will try to encourage the next generation agrometeorological experts through Global Center of Excellence in Research and Education in AgroMeteorology (GCREAM) including graduate programmes under the framework of GENRI as a governing hub of Global Initiatives in AgroMeteorology (GIAM of CAgM). It would be coordinated under the framework of GENRI as a governing hub for all global initiatives such as GFAMS, GAMPP, GAPON including WAMIS II, primarily targeting on GFCS implementations.

As the Korean navy's capabilities increase, it becomes increasingly necessary to develop sufficient navigational capabilities and train proficient seafarers. However, in terms of securing personnel resources, seafarers will need to be utilized more effectively due to the population decline of recent years. This paper reviews the use of civilian maritime personnel to research potential resources and uses the U.S. military sealift command as a benchmark. As a result, it has been found that it is possible to increase naval combat capability through the establishment of like a military sealift command organization to operate defense civilian support vessels. In addition, it is possible to train civilian seafarers by utilizing the current national education system through existing maritime universities. Furthermore, taking these actions will allow the ROK navy to operate its onboard ship reserve service and designated international ship system more efficiently.
