The flag State is primarily responsible for implementing international maritime conventions(IMO conventions) and national laws and other standards as far as its own vessels are concerned, on the other hand the port State exercise its rights for the safety and marine environment under international law especially UNCLOS within port and territorial sea. In particular, the port State may take appropriate measures including detention of ships identified as sub-standard vessels which are considered as port State's supplementary role aiming for implementing international and national and regulations. But in the course of implementing port state control, international disputes may happen between port state, coastal state and flag state in spite of making all possible efforts to avoid these disputes. This paper aims to consider legal grounds on port state control(PSC) in international conventions and national laws concerned and deals with contradictions between international and national law arising from exercising PSC by port state control officers(PSCOs).

온대와 열대의 연안해역에 형성되어 있는 해초지는 해양생태계 중 생산성이 높고, 작은 크기의 해양동물들이 큰 동물들로부터 보호되고 있는 해양환경을 이루고 있다. 특히 본 조사해역인 호주 동북부 해역은 Cleat Barrier Reef과 더불어 열대성 해초가 많이 밀생되어 있어서 많은 동물들이 서식하고 있다. 어류의 먹이습성 연구는 그 어류가 속해 있는 생태계의 기능적인 면을 이해하기 위한 기초자료를 제공한다. (중략)

The COVID-19 pandemic reminded us again of the importance of essential workers who perform their roles in maintaining the stability of people's daily lives worldwide. Therefore, the International Maritime Organization and overseas countries designated seafarers as essential workers and proposed relevant measures for their protection to enable them to perform their role. In particular, the International Maritime Organization (IMO) urges related associations and member states to support safe boarding and disembarkation of seafarers. However, Seafarers were restricted from boarding or disembarking, shore leave and hospital treatment in certain countries owing to extreme nationalism. This study compares and analyzes the cases of international organizations and major overseas countries to provide a logical basis for the protection of seafarers who play an essential role in the safety of the global supply chain despite the COVID-19 pandemic. This study identifies the need to protect seafarers and their roles as essential workers in the shipping industry and suggests necessary aspects and institutional improvement measures for improving seafarers' working environment to strengthen the shipping industry's resilience. This study is expected to serve as future basic data for national policies aimed at reflecting the roles of seafarers as essential workers and the need to protect them.

Oil fences effectively prevent the spread of oil spilled in the sea, thereby reducing the damage to the marine environment. However, the fence is damaged by oil and structures at the accident site and is discarded. When incinerated disposal method for discarded fences, fine dust, and harmful materials are generated. Moreover, as a part of the damaged fence is dumped into the sea, it may cause secondary environmental pollution, such as microplastics. Therefore, in this study, durability was measured using the most common solid foam type oil fences. As a result, the reduction rate of after five days of contact was 13 % in seawater and 3 % in oil, affected by temperature changes. Thus, the durability of the fence should be improved because it is exposed to seawater and oil and affected by wind, light, and waves depending on the weather conditions. Therefore, we suggest a method to improve the oil fence inspection to strengthen the durability of the fence's fabric part.

4차 산업혁명 기반의 자율화, 무인화 등 선박기술의 새로운 패러다임이 지속적으로 제시되고 있으며, 이는 자율운항선박울 둘러싼 주변 환경에도 큰 영향을 미칠 것으로 예상되고 있다. 이 중 항만 및 연안 수역의 선박교통 안전 및 효율성의 확보와 해양환경 보호를 위하여 시행되고 있는 해상교통관제 서비스의 경우에도 자율운항선박의 출현에 대비한 사전 준비가 필요하다. 본 연구에서는 현행 해상교통관제업무 분석 및 현직 관제사를 대상으로 한 설문조사를 통하여 자율운항선박에 대한 관제업무 절차 마련을 위한 기초 연구를 수행하였다. 연구의결과로 무인 자율운항선박을 고려한 디지털 정보교환 체계 기반 해상교통관제 시스템에 대한 개념을 제시하였다.

Zostera marina (ZM), a type of seagrass registered as a marine protected species in South Korea, provides valuable ecosystem services to humans, such as improving marine water quality, providing food, spawning grounds and habitats for marine life, and absorbing carbon dioxide. Therefore, the government is seeking to preserve ZM by designating ZM-protected areas. This study examined the public willingness to pay (WTP) for the preservation of ZM using contingent valuation. The one-and-one-half-bounded model was adopted for WTP elicitation, and the single-bounded model was also applied for comparison. The spike model was employed to deal with many zero WTP responses. The household average WTP was estimated as KRW 4,087 per year, securing statistical significance. The national value was KRW 84.1 billion per year. The preservation value of ZM estimated in this study can be used as important data for economic analysis of various projects or policy implementation for its preservation.

As GNP increases, many peoples need the seafood with high quality. In Korea, aquaculture is one of major incomes for fishing households and records $50.6\%$ of total incomes for domestic fishery. The loss of aquaculture farm due to thievery at sea increases every year. In this research, we propose the system model for development of radar surveillance system, which protects aquaculture farms. For the proposed system, general requirements are described Our system is cost-effective when it is applied to domestic fishing households.

While fishery has been continuously suffering from deteriorating economic feasibility, the amount of the deposited marine litter has been increasing due to an increased number of marine leisure tourists which are caused by an improved quality of life and five-day work week. In addition, the fishery area has been reduced by the reclamation projects and it is being destroyed by marine pollution with a variety of contaminants coming from land and sea. To protect and improve fisheries in these poor conditions, Korean governments have implemented the submerged marine litter collection projects. However, previous research results on the marine environment and resources indicate that it requires a lot of time investment to achieve tangible results of such improvement. The 300 billion won marine environment and resource investigation project has been executed since July 2004 by Korean governments, which demands strategic approaches to obtain more effective and satisfactory results before the project expires in 2013. Ocean environment research institutes and governments need to cooperate each other to gain efficient and reasonable achievement by identifying and linking related projects. This study suggests that the marine environment and resources investigation projects should run parallel with the submerged marine litter collection projects on mutually agreed research items in the identical area of the ocean to obtain cost-effective improvement of marine environment and fishery conditions.

All people have human rights that should be protected, and today, the importance of protecting human rights is emphasized in all areas of society. The industry is also carrying out activities to protect the human rights of workers, such as implementing human rights education for human rights management and preparing a response system for human rights violations. However, due to the closed environment and special working conditions, seafarers on board are often placed in a blind spot in human rights protection. In particular, a number of cases of human rights violations concerning beginner seafarers, including cadets, have been identified, and relevant research is insufficient compared to other occupational groups. Jobs that restrict basic human rights cannot be envied by anyone. In this study, implications and problems were derived based on the results of a human rights survey of cadets, and cases of human rights violations, and improvement measures were proposed. The cadets had a very negative perception of human rights violations before boarding. However, it was found that their perception changed after boarding. It was confirmed that cadets have unnecessary fears and concerns before boarding. Improvement measures include the establishment of a legal system for the status of cadets, measures to alleviate non-physical human rights violations, improvement of human rights violations handling procedures and response systems, and enhancing the effectiveness of human rights education.
