  • In Vessel Traffic Service, the management information on marine traffic control is almost transported by VHF. It is so difficult to exchange a lot of the related information necessary for marine traffic control exactly and in real time. Aiming at improved visualized data transporting network, we examine the methods for transporting and displaying the data on marine traffic controls. In this paper, we design the information networks established by broadcasting method and by internet method using home page in order to manage marine traffics in Masan port.

  • This study determined that the four corrosive characters of carbon steel in the marine splash zone (MSZ) in China's four sea areas. It has a range and a corrosion peak value. The rust in the MSZ plays the role of "depolarizer" in the cathodic process of corrosion. The growth law of the rust layer in MSZ has a character of "annual ring". In addition the reasons causing serious corrosion of carbon steel in the marine splash zone has been discussed in this paper.

  • The market for anti-inflammatory drugs is large and is expanding rapidly as populations age. Key to the development of new drugs are novel chemotypes. Marine organisms harbour a diverse range of unique compounds with applications in a multitude of disease indications. This review looks at anti-inflammatory compounds isolated from New Zealand marine organisms.

  • Pyricularia oryzae (P. oryzae), the cause of rice blast, is one of the most important fungal pathogens of rice. Seventy strains of marine fungi were isolated from marine algae, and it was measured antifungal activity against P. oryzae. Metabolites of marine fungus A-248 which isolated from marine algae showed strong antifungal activity against P. oryzae. The antifungal substance from the metabolites of marine fungus A-248 was extracted with ethylacetate, and then purified by preparative TLC and reverse-phase HPLC. The minimum inhibitory concentration (MIC) value was $0.18\mu g/mL$ for the antifungal activity of the substance purified from A-248 metabolites. The purified substance was similar to antifungal activity of rhizoxin, which is a commercial antifungal agent.
