This study provides the unified Korea with military integration method in order to prepare the reunification of South and North left only divided country in the world after World War Ⅱ and the sudden change in N. Korea. And also, it presents preceding conditions for military integration by case study of Germany, Yemen and Vietnam. Agenda includes theoretical consideration, a lesson from the cases of reunified countries, national defense policy and military strategy for the unified Korea, some military integration types and preparatory task list, and conclusion ; the best military integration method to fit the Korean peninsula issue. Preparatory task list to accomplish consensual unity of absorption presented as conclusion in this paper includes following: First, the most important thing is maintaining strategic superiority by overwhelming military force since only overwhelming power guarantees stability of unification. Second, diplomatic effort should be concentrated in shaping international condition for reunification - 4 powers around the Korean peninsula support reunification of South and North - since reunification is almost impossible without their support. Others, installing promotion organization and training professional to lead military integration, estimate of initial the unified Korea military force, efficient method for assumption and management of N. Korea military force are extra issue to solve after military integration As if any international politics scholar could not forecast reunification of Germany, the Korean peninsula reunification would be also happen without any warning. Therefore, the future unified Korea is crying out for understanding and bond of sympathy on reunification and military integration in order to mitigate risk of trial and error and make reunification progressed by our intend.

The modified in-line mixer which was suggested in this study for small water treatment facilities was evaluated on the performance of coagulation. For the objectives of this research, computational fluid dynamics(CFD) simulation was applied for analysis of flow characteristics within the modified in-line mixer. For verifying the results of CFD simulation, wet tests for the pilot plant were conducted. The wet test was to measure the actual coagulant dispersion distribution on the overall crosssection at a distance of 5.5D from the chemical injection point. From the results of CFD simulation and wet test, it was shown that the coagulant dispersion within the modified in-line mixer was occurred more uniformly than within the existing PDM(Pump diffusion Mixer). The results have confirmed the modified in-line mixer had several advantages compared with the existing PDM in terms of dispersion efficiency.

Rapid sand filters in water treatment plants (WTP) is one of the most important step in order to remove fine particle including pathogens such as Criptosporidium and Giardia. Filters should be assessed based on their capability to achieve a treated water quality of less than 0.1 NTU on a continuous basis to ensure the integrity of the filtration process as a viable barrier in the treatment scheme. This is less than the 1.0 NTU standard, but operation of filters to produce filtered water quality confidence that pathogens are being removed prior to the last barrier, disinfection. In this study, to optimize existing filtration unit process, rapid sand filters working in S-WTP were evaluated for various factors. The results of comprehensive performance evaluation were followings. From the filter media analysis, effective size and uniformity coefficient of media was 0.90∼1.0 ㎜ and 1.44∼1.47, respectively. Therefore, the replacement of media is needed to optimize filter performance. Media loss was caused by air binding in the filter bed and improper operation of backwashing process. The ratio of the water used for filter washing to the amount of filtered water was 2.5∼3.0% during the winter and 1∼2% in the summer. At the beginning of a filter run, filtered water turbidity was over 0.5 NTU during about 20 min. Shorter filter run lengths was attributed to an overabundance of filter clogging algae (Synedra. sp), air binding, and too much floc in the filter influent.

The artificial aeration in the middle and the small scale reservoirs is widely used to destroy the stratified layer and algal boom. This study has been conducted at the Youncho reservoir located in Keoje island since Jan. 2000 to suggest the most suitable control strategy of the artificial aeration and reduce the side effect. The main results obtained from this research are as follows. The starting time of aeration for destratification was adjusted from the end of March to the beginning of April when the natural stratification is started. In order to prevent an anoxic condition the artificial mixing should be started by the middle of April when the DO in hypolimnion is dropped to less than 5mg/ℓ. The decrease DO, caused by the increase in water temperature, spreads rapidly from hypolimnion to themocline. Thermal stratification disappeared after the onset of artificial aeration within 7 days in the Yuncho reservoir. The air diffusers decrease water temperature in the layer of epilimnion and thermocline, but rise it in hypolimnion. The continuous operation of air diffuser prevent the stratification and anoxic condition in hypolimnion despite of the rising of water temperature and algal abundance. The algal abundance is not observed in effective zone by aeration, The turbidity rising problem induced from the aeration is avoided by keeping an air diffuser about 1.5m high from the bottom of lake. During the summer season, ceasing the aeration should be decided carefully. And also, it is necessary to operate the system it considering weather and temperature, and depending on the number and the position of aerators.
