The rapid industrial and technological development has made the human activities for the utilization of marine resources more complex. Marine spatial management is a space-based approach. It is a comprehensive and integrated management approach. The ultimate goal of marine spatial management is the "sustainable use" of marine resources. The partial approach is applied in the existing marine spatial management, mainly coastal zones which involves integrated approach. Also this showed various limitations including restricted mostly to coastal zones, and limitation to implementation tools. However, for marine spatial management to have a reasonable approach that attaches importance to the relationship between humans and the holistic ecosystem, it is important to internalize a central principle in marine spatial management that focuses on the sustainable use of marine resources. In the present study, four central principles are proposed that will eventually be applied through marine spatial management planning tools. These principles are 1) the establishment of a cooperative decision making and planning system that is based on stakeholder participation; 2) scientific assessment of the current status and impact on the basis of ecology, sociology, and economics; 3) reasonable and optimal spatial assignment based on the forecasting of future-use characteristics and environmental changes; and 4) ascribing importance to the implementation of the results of rational planning processes.

This study is given that on the bridge construction in marine by GPS, specially, choice of station for footing construction of marine bridge. You can get positive datum in the checking of marine excavation, if you use together Total Station and GPS. In the result of comparision of upper surveying methods, Surveying datum is gotten error of less than 30mm(The depth of water 10～l5mm, station 7～10mm). This study show that hereafter if you use GPS in bridge construction in marine you can get accurateiy datum.

This study is to suggest the legal issues and some question to solve on the approved books in fisheries and marine sciences education. The results of the study are following. First, It discuss the legal meaning on the approved books. The meaning of the approved books means the curriculum books are subject to an approval by the Minister of Education, Science and Technology in order to use term in case where there exist no government-designated books and authorized, or where it is difficult to use term or it is necessary to supplement them. Second It deals with the legal issues on the approved books in fisheries and marine science education. The main issue is in harmony with the regimentation and self-regulation of education. This matter is the legal problems on the power for the standards of the textbooks approval and the rights for the organization of the textbooks. Third, It treats the problems of the approved books in fisheries and marine sciences education. The problems is system of statute and concept of approved books, the rights of nation and local government, standards of approved books, and writing and practical use of approved books. I generalize legal issues on the approved books in fisheries and marine sciences education. Hence, it is necessary to deeply study each subject in the legal aspect of the approved books in fisheries and marine sciences education.

The use of ionizing radiation and radioactive elements is becoming increasingly popular with the rapid developments in nuclear technology, radiotherapy, and radio diagnostic methods. However, ionizing radiation can directly or indirectly cause life-threatening complications such as cancer, radiation burns, and impaired immunity. Environmental contamination with radioactive elements and the depletion of ozone layer also contribute to the increased levels of radiation exposure. Radioprotective natural products have particularly received attention for their potential usefulness in counteracting radiation-induced damage because of their reduced toxicity compared with most drugs currently in use. Moreover, radioprotective substances are used as ingredients in cosmetic formulations in order to provide protection against ultraviolet radiation. Over the past few decades, the exploration of marine algae has revealed the presence of radioprotective phytochemicals, such as phlorotannins, polysaccharides, carotenoids and other compounds. With their promising radioprotective effects, marine algae could be a future source for discovering potential radioprotective substances for development as useful in therapeutics.

The biodiesel used as an alternative fuel for diesel engines is well- known, however the price of the bio-diesel is still higher than conventional diesel oil (DO) by 10% to 15% depending on a kind of bio-oil and a country producing the bio-diesel. One of idea to reduce the price of bio-diesel is to use the pure bio-oil as fuel for marine diesel engines, because to use the pure bio-oil as fuel without the esteritification process can reduce the price of bio-fuel. At present time, some experts in some countries who have been carrying out experiments on the use of pure bio-oil produced from rape seeds, sunflower seeds... as fuel for marine diesel engines have achieved important results. In recent years, at Vietnam Maritime University we also have been using the pure palm oil and its blended fuel (Palm oil and DO) as fuel for marine diesel engines in laboratory and on board of ships. The blended fuel is a mixing fuel of the pure palm oil and diesel oil with content of pure palm oil by 5%, 10%, 15%, 20% and 35%. In this paper, we would like to present some results from our experiments to investigate the impacts of using the palm oil and its blended fuel on the important technical features of the fuel supply system of marine diesel engines such as the fuel supply amount for one cycle, fuel supplying pressure, ignition delay time and so on. The results from the research will be good fundamental parameters to support proper operation of marine diesel engines using bio-oil and blended fuels as alternative fuel in near future.

Many marine wastes such as seaweeds are casted aside at the seasides. So, the objective of this study is to apply the marine wastes to the concrete. To this end, mortar and concrete tests with the marine wastes have been conducted. The results of the present mortar and concrete tests indicate that the mortar and concrete with marine wastes admixtures exhibits very low permeability. The present study provides a firm base for the use of very low permeable concrete and the application of the marine structures and the submerged structures.

국민의 여가시간 증대로 친수시설에 대한 해양관광 수요의 증가가 예상되며, 이에 주요 항만이나 지역의 어촌, 경승지 및 명소에 어울리는 조형미를 갖춘 등대시설을 관광자원화하여 이러한 수요를 충족시킬 필요가 있다. 또한 우리나라에 등대가 들어선지 어언 100여년이 지나면서 훼손된 등대를 새롭게 신축하고 있는 시점에서 우리나라 등대건축을 진단하고 그것들의 보존과 적극적인 해양관광자원으로서의 활용방안 연구가 필요하다. 이제 등대는 전통적인 기능과 역할에 충실한 항로표지일 뿐만 아니라 온 국민이 향유하고 체험하는 새로운 관광시설이자 공간으로 적극 개발되어야 할 것이다. 이러한 맥락에서 본 연구는 국내 등대 개발사례를 검토하여 등대의 해양관광자원으로서의 개발을 위한 방안을 제시하였다.

This study aimed to explore sustainable fashion design plans and directions by analyzing Marine Serre's collection. Previous research was reviewed to derive classifications of the aesthetic characteristics of sustainable fashion design. This classification was then used to analyze the characteristics of the Marine Serre collection. Design analysis was conducted on Marine Serre's 2018 FW to 2023 SS collections. Marine Serre's sustainability characteristics are functionality, surprise, handicraft, and inclusion. The results are as follows. First, functionality is the highest among the four characteristics and includes the functionality of movement, the functionality of form, and futurism. This characteristic was observed in the use of all-in-one body suits, pockets, and workwear, showing the will and values of designers who value daily activity. Second, surprise includes the scarcity of materials and the unexpectedness of composition. The value of the clothing is enhanced by the use of scarce materials not typically used in clothing. In addition, Marine Serre is highly regarded for expanding clothing into life by incorporating material upcycling into the theme of the collection. Third, handcrafted features include exaggerated decorations, logo, retro designs, and natural properties, and intentional utilization is differentiated. Marine Serre's signature pattern suggests a suitable expression for the fabric to use the crescent moon for the season. Fourth, the collection expresses themes of inclusivity and cultural diversity. The results indicate that Marine Serre wants to contribute to a better future characterized by global coexistence.
