The results of COD researched on August of 2004 were 6.8 ppm in North Mokpo inner Bay, 4.4 ppm in front of YongSang Bank and 4.6 ppm in front of ShinAn Beach Hotel which is over III level Marine-Environmental Standard. The other five stations sea water quality of Mokpo inner bay were reached II-III level. Concentration of total nitrogen range from 1.23 ppm to 3.56 ppm and total phosphorous was range from 0.07 ppm to 0.12 ppm which were II-III level. This results show that the Mokpo inner bay is unsuitable for aquaculture and growth of fish and for use of marine resort, it can be only available for industrial and harbour use. In results of estimated point source flow into Mokpo inner bay, the occupation ratio from YoungSang river in total inflow of TN and TP were up to 49-89 % respectively. It is indicate that in order to improve the water quality of MokPo inner bay have to control the discharge from YoungSang river first of all, then control the discharge from North Harbour domestic wastewater treatment, InAm river and NamHae domestic wastewater treatment.

Manila Bay is home to the Port of Manila with three harbors: North Harbor, South Harbor and MICT(Manila International container Terminal). There is an adjacent fishing port to the north and another port across the Bay, the Limao Port. This study focuses on the volume of traffic movement in the Bay area taken from Manila VTMS raw data of the arrival and departure movements only. It is a two-year period of study of 2010 and 2011 traffic volume. It divides the data according to their numbers; to their sizes measured in gross tons; to the time of vessels' movements, whether daytime or night-time; and to each voyage trade: domestic or foreign. Quantitative values are calculated from the raw data based on the whole population of the two-year period. The results are illustrated by tables and graphs. Statistical measures are applied to determine the spread and frequencies of the data and test any significance from the hypotheses. These are shown in the tabulated form and interpreted to give a better picture of the frequency and volume of traffic. In the end, a summary is offered where it is hoped that this paper will propel further studies of improving the safety behavior in the premier port of the country.

The study investigated the physicochemical characteristics and the ecological risk of the Northport sediment in B city and the releasing properties of heavy metals into seawater during the resuspension also studied. The major components of the sediment are fine silt and clay which contains high organic matter and AVS (Acid volatile sulfide) and the ecological risk of the heavy metals in sediment also very high. The release rate of heavy metals into seawater was in order of Pb>>Cu>Cr>>Zn>Cd during the resuspension in a batch experiment, and the heavy metal release mainly attributed to the oxidation of metal sulfides. Heavy metals which came from easily oxidisable metal sulfides rapidly contaminated seawater within about 1.0 h of the sediment resuspension. The sulfide oxidation during the resuspension increased the residual fraction of heavy metals in the sediment, decreased the organic bound fraction, and changed the other fractions of heavy metals in the sediment. The release of heavy metals from the sediment during resuspension was affected by the resuspension time, the oxidation rate of metal sulfides and resuspended concentration of the sediment particle.

The results of COD concentration on August of 2004 were 6.80 ppm in North Mokpo Inner Bay, 4.42 ppm un front of YongSang Bank and 4.60 ppm in front of ShinAn Beach Hotel which is over III level Marine Environmental Standard. The others researched five stations sea water quality of Mokpo inner bay are reached II-III level. The concentration of total nitrogen range from 1.23 ppm to 3.56 ppm and total phosphorous concentration was range from 0.07 ppm to 0.12 ppm which are to be II-III level. This results show that the Mokpo inner bay is unsuitable for aquaculture and for use of marine resort, it can be only avaliable for industrial and harbour port use. In this study, we researched 12 point source flow into Mokpo Inner bay. The rate from YoungSang river in total inflow of TN was up to 70-93 % and rate of TP was up to 31-91 % respectively. In this results, we have to control the discharge from YoungSang river first of all then control the discharge from North Harbour domestic wastewater treatment, InAm river and NamHae domestic wastewater treatment in order to improve the water quality of Mokpo Inner bay.

The steel cargoes as the core raw materials for the manufacturing industry have important roles for increasing the handling volume of the port. In particular, steel cargoes are fundamental to vitalize Port of Incheon because they have recognized as the primary key cargo items among the bulk cargoes. In this respect, the IPA(Incheon Port Authority) ambitiously developed the port complex facilities including dedicated terminals and its hinterland in northern part of Incheon. However, these complex area has suffered from low cargo handling records and has faced operational difficulties due to decreased net profits. In general, the import and export steel cargo volumes are sensitively fluctuated followed by internal and external economy index. There is a scant of research for forecasting the steel cargo volume in Incheon port which used in various economy index. To fill the research gap, the aim of this research is to predict the steel cargoes of Port of Incheon using the well established methodology i.e. System Dynamics. As a result, steel cargoes volume dealt with in Incheon port is forecasted from about 8 million tons to about 10 million tons during simulation duration (2011-2020). The Mean Absolute Percentage Error (MAPE) is measured as 0.0013 which verifies the model's accuracy.

This study was conducted to investigate the benthic condition around Busan Port by analysing spatio-temporal distribution pattern of polychaete community and some benthic environmental factors. Field survey was seasonally carried out at 15 stations covering in and outside of Busan Port from February to December, 2007. Water temperature, salinity and the type of surface sediment showed little changes among the stations, but factors related to organic enrichment such as TOC, AVS, coprostanol showed an obvious contrast, especially between in and outside of Busan Port. A total of96 species occurred and mean density was 1,814 ind./$m^2$. Species richness was higher at outer port than inner port, but density was higher at inner port. Dominant species were Aphelochaeta monilaris, Magelona japonica, Pseudopolydora paucibranchiata, etc. and many of them were typical species of organically enriched area. From the multivariate analyses, the whole study area was composed of two distinct polychaete communities located at the inside and outside of the port, and seasonal changes didn't have any influential effects on the structure. Coprostanol and AVS, indicators of organically enriched condition, well explained the community structures of polychaete worms in the vicinity of Busan Port. In this context, the innermost area of North Harbor was in a highly enriched state.

The purpose of this paper is to show the clustering measurement way for Korean container terminals by using neural network based SOM(Self Organizing Map). Inputs[Number of Employee, Quay Length, Container Terminal Area, Number of Gantry Crane], and output[TEU] are used for 3 years(2002,2003, and 2004) for 8 Korean container terminals by applying both DEA and SOM models. Empirical main results are as follows: First, the result of DEA analysis shows the possibility for clustering among the terminals and reference terminals except Gamcheon and Gwangyang terminals because of the locational closeness. Second, the result of neural network based SOM clustering analysis shows the positive clustering in clustering positions 1, 2, 3, 4, and 5. Third, the results between SOM clustering and DEA clustering show the matching ratio about 67%. The main policy implication based on the findings of this study is that the port policy planner of Ministry of Land, Transport and Maritime Affairs in Korea should introduce the clustering measurement way for the Korean container terminals using neural network based SOM with DEA models for clustering Korean ports and terminals.

This study analyzes the process of growth of Busan from a fishing village to the capital city of South Gyeongsang Province and the central city of transportation and commerce, and an industry with records. The results of the analysis are as follows: after the port opened in 1876, there has been a decline in settlement spaces in Dongnae; on the other hand, there has been an increase in migration spaces around the port of Busan. Waegwan (倭館) nearby Yongdusan Mountain (龍頭山) was changed to the Japanese concession; thus, the number of Japanese moving into Busan had rapidly increased. As a result, the Japanese government carried out reclamation work for securing available lands for the construction of port facilities and other facilities. The Japanese government built public offices and houses, as well as production facilities for daily necessities around the port of Busan. The opening of the Seoul Busan railway (京釜線) and the cross-channel liner between Busan and Shimonoseki (釜關連絡船) led to the growth of Busan and the development of its status. At this time, as the main industry of Busan was trade, Busan had grown as a commercial city. As Busan had grown as a central city of transportation and commerce, the provincial government building of Gyeongsangnam-do (慶尙南道) moved to Busan. Thus, Busan became the central city of local politics and administration. After the Land Survey Project, a large scale of farmers were recruited for low-wage work in the new port. Because of the abolition of the corporation law, Japanese capitalists moved into their colony in Busan. There, large-scale factories, such as the Joseon cotton textile factory, were established. Through this process, the locality of Busan was changed from a fishing village to a commercial city and, finally, to a city of commerce and industry.
