In this study is the tide Saemangeum embankment management and sea side slope behavior analysis, and surveillance and management of the numbers 1 and 3 tide embankments installed in each of the previous years was conducted. Results of the numbers 1 and 3 devices showed that sideways movement by the clinometers were slight, and in the case of the subsidence meter, efflux of find wire dredging caused by damage to the filter mats resulted in serious subsidence at the STA. No. 20+30 row 1 EL+3.0m, EL-6.0m, row 2 EL-2.0m points of device number 1. Results of the piezometer showed that changes in the tide levels at low and high tide caused changes in water pressure at regular intervals. Therefore, it is established that tide embankments are stable in all areas save the STA. No. 20+30 point of device number 1.

A tide embankment is one of the socially important structures so as to increase the capacity of agricultural and industrial water, to expand the land such as farmland and building sites, and to improve the capacity of drainage. Therefore, a tide embankment should be maintained as safely as possible so that any hazardous troubles could not happen since all sort of disasters related to tide embankments can cause casualties and damage national finance. The main purpose of this study, hence, is to help staffs in charge who build and maintain tide embankments with establishing the maintenance criteria of tide embankments in order to evaluate the safety of tide embankments based on the results derived from setting a measuring instrument and then analyzing the measurements for effectively maintaining the OO tide embankment that will be designed and built.

Generally, as the sea dyke permits certain amount of seawater permeation, the structure is the one that allows a freshwater lake to take form due to the disparity of density between seawater and freshwater, and the permeating characteristic of filling material. In case of a sea dyke which deteriorated, the phenomenon of excessive permeation occurs due to the minute filling material being washed away for a long time; Although an excessive amount of permeation occurs in the sea dyke which is built recently in the deep sea at large scale section, the investigation and evaluation method about it is absent, which requires a research on the long-term safety of sea dyke and the effect upon a freshwater lake that takes form. Saemangeum is the world's largest and longest sea dyke built in the deep sea; Especially, even if the 2.7㎞-long final closure section segments extends a bottom protection into the lakeside, the layer where the permeability is relatively high is connected with seaside and lakeside. Consequently, in this study, after the construction of final closure section for Saemangeum the amount of permeated water is examined and analysed; Is also analysed the effect of seawater that permeates the sea dyke section upon stability of the sea dyke and its freshwater lake that takes form; Based on comprehensive result of research, some protective counter measurement against excessive permeation are suggested.

스텝 붙이 활주형 모터보트 선미부가물의 횡요저감효과에 관한 연구
강병윤(BYUNG-YOON KANG),박충환(CHUNG-HWAN PARK) 한국해양공학회 2008 한국해양공학회지 Vol.22 No.4
It is hard to find experimental data for a model test of small high-speed planning boats. It is difficult to verify the performance seen in a model test for ahigh-speed boat because the ship-model scale-ratio is very small and the flow velocity of the circulating water channel and the X-carriage speed of the towing tank are restricted. Therefore most hull-form designs for high-speed small boats depend on the sea-trial test results for similar boats or evaluation through numerical calculations. This study investigated the anti-rolling effect of the stern sub-body in a 50-knot class planning boat. To carry out this work, new model test procedures were set up in the actual sea. Using this method, the anti-rolling effect of the stern sub-body was investigated. A stern sub-body attached to a planning boat was proved to be effective in reducing the roll and pitch angle.

This study carried out a series of field scale test for estimating field application of electrokinetic grouting technologies which was new method to improve a shear strength in low permeable ground using electrokinetic phenomenon. For configuring field application effectively, various factors affecting the electrokinetic grouting method in bench scale test were used to design the field scale test. The test was conducted 3 kinds of condition such as electrode decomposition, electrokinetic injection and hybrid method. The cone penetration test was conducted to obtain the change of cone penetration resistance values of improved field ground during field test. After the sampling process which in the same point, the various geotechnical test, three axial compression test and standard consolidation test to analyze the origin of strength increase.

A study was performed to examine the soil environment, vegetation type to the inside slope of sea dike. The soil pH was about 8.5, electric conductivity was 4.59 dSm<sup>-1</sup>, soil strength was 12.1mm, organic matter was 0.21 %. The vascular plants of the inside slope of sea dike were consisted of 101 taxa such as 26 families, 80 genera, 93 species, 8 varieties, 1 hybrid. The life cycle of the plants was annual 38.6%, biennial 14.8%, perennial 46.5%. As it compared with consistency ratio in the flora of korea, the distribution of annual, biennial appeared highly. From this examine, it appears that the environment need soil improvement using water holding materials and organic supplements.

In-situ soil remediation mechanism through the vertical drains (VDs) is analyzed with numerical model as the error and complementary error function. Results from in-situ test and analysis indicate that the contaminant concentration ratio as initial one ( C/$C_0$) increases as the radius ratio ( r/R) increases from the injection well, and also increases as the depth ratio ( z/ H) increases from the top of contaminated area. The elapse time needed to attain $50\%$ and $90\%$ clean up level ($ t_{50},\;t_{90}$) increases as the radius ratio ( r/R) and the depth ratio ( z/ H) increase. As above results, the procedure of soil flushing in contaminated area using vertical drains makes progress from the top of injection well to the bottom of extraction well.

Various kinds of ballast water treatment systems (BWTS) have been developed corresponding to reinforced IMO rules for marine environment. Some of them got the certificate of IMO and others are waiting for it. Selection of optimum BWTS is very important. Optimum BWTS means not only functional requirements but also economic efficiency. This paper presents economic analysis model for optimum BWTS according to ship type and size. In this study 10 kinds of BWTS whose initial installation cost and maintenance cost are known are analyzed based on present worth method. It is assumed that all BWTS satisfy minimum functional requirements and we need to consider different economical efficiency. Through the economic analysis we could select optimum BWTS.

In this study is field test and monitoring performed at the Saemangeum area to identify field applicability and improvement plan of collapsing protection method. Considering ground characteristic and external condition, the target site divided in six sections (application of 6 type method) which were 25m width on 00 area in November 2007. After tests, the monitoring by 6 type valuation basis performed to assessment of field applicability for collapsing protection method from December 2007 to October2008 (11 seasons). The results of monitoring in field, flow out of soil particles happened by wave, freezing & thawing in foundation and back part. Therefore, there is need the reinforcement by materials for prevents flow out of soil particles. In case of application of vegetation method, construction season and management is important for determination of suitable vegetation and stable taking root.
