It remains that South and North Korea are the most conflict ridden region of the world and at high risk of military collision despite the appropriateness and necessity of unification between South and North Korea. Meanwhile, our government has pushed ahead with exchange between the two countries in many different fields to defuse this conflict and tension. But, these efforts have made it less meaningful as South-North relations are strained again. This can be because temporary recovery of political relation didn't proceed to system improvement and economic cooperation. This study on exchange cooperation of circulation · distribution between South and North Korea begins with expectation that this study will be based on realizing free circulation · distribution for the unification and making an economic bloc through exchange cooperation of circulation · distribution. To expand economy exchange and cooperation between the two nations, the field of circulation · distribution should be developed. On the basis of this discussion, this study suggests that cooperation relation and the mood of reconciliation created by political declaration are institutionalized in the national consensus and exchange should be expanded in the economic field as well as political field.

Three baggage allocation methods of passenger-baggage hybrid train in restricted railway transportation capacity including round conveyor system, vertical circulation system, and horizontal circulation system are presented. Loading/Unloading time is calculated based on the volume transported from Busan to Seoul via Daegu, Daejeon, and Osong with the parcel company P's logistics data. The horizontal circulation system shows less baggage volume capacity to be allocated and the maximum loading/unloading time with 434 secs. The vertical circulation system presents more loading time, but it shows best result with 408 secs. Loading/Unloading times are compared for each system and useful method is presented to improve transportation efficiency of the train.

The organic farming was begun with principles and values like environmental friendliness, symbiosis, and cooperation and circulation. And there has cut keen market competition, as sales and market size of organic agricultural products have been much larger. Thus producers and consumers have kept up with the market trend making light of the philosophy and principle of organic agriculture. So cases of fraud or false certification have been increased since 2010. Accordingly, not a few consumers have distrusted of the safety of organic agricultural products. And the status of organic agriculture has shown downward trend and market size of organic agricultural products has been reduced since 2012. Thus the income of organic agricultural farmers hasn't been increased. It is thought that present organic agriculture fell into the crisis. Now, organic agricultural farmers should practice farming methods based upon the philosophy and principle of organic agriculture in order to overcome its crisis.

One of the factors influencing the climate around Korea is the oceanic-atmospheric variability in the tropical region between the eastern Indian and the western Pacific Oceans. Lack of knowledge about the air-sea interaction in the tropical Indo-Pacific region continues to make it problematic forecasting the ocean climate in the East Asia. The 'Tropical Indo-Pacific water transport and ecosystem monitoring EXperiment (TIPEX)' is a program for monitoring the ocean circulation variability between Pacific and Indian Oceans and for improving the accuracy of future climate forecasting. The main goal of the TIPEX program is to quantify the climate and ocean circulation change between the Indian and the Pacific Oceans. The contents of the program are 1) to observe the mixing process of different water masses and water transport in the eastern Indian and the western Pacific, 2) to understand the large-scale oceanic-climatic variation including El Nino-Southern Oscillation (ENSO)/Warm Pool/Pacific Decadal Oscillation (PDO)/Indian Ocean Dipole (IOD), and 3) to monitor the biogeochemical processes, material flux, and biological changes due to the climate change. In order to effectively carry out the monitoring program, close international cooperation and the proper co-work sharing of tasks between China, Japan, Indonesia, and India as well as USA is required.

The purpose of this study was to investigate the effects of circulation exercise on health related fitness and metabolic syndrome risk factors obese in middle age women. Twenty, obese middle age women($BMI<25kg/m^2$) composed of circulation exercise group(EX, n=10), the control group(CON, n=10). The variables of health related fitness, metabolic syndrome risk factors were measured in all the subjects before the start and after the end of 12 week circulation exercise program(60~80 %HRR, 3 times per week, 30~40 mins). The test data were analyzed by paired t-test and repeated ANOVA, and the alpha level of p<.05 was set for all tests of significance. Health related fitness and metabolic syndrome risk factors were measured pre and 12 weeks of post exercise training. %body fat(p <.01) was significantly decreased in EX group compared to CON group. LBM(p <.05), muscular endurance(p <.05), flexibility(p <.05) and cardiorespiratory endurance(p <.001) were significantly increased in EX group compared to CON group. WC(p <.05), SBP(p <.01), DBP(p <.05), Glucose(p <.05) and TG(p <.05) were significantly decreased in EX group compared to CON group. HDL-C(p <.01) was significantly increased in EX group compared to CON group. These results suggest that 12 weeks of circulation exercise training improves health related fitness and metabolic syndrome risk factors. Thus, this newly proposed circulation exercise modality can be a useful therapy to improve both health related fitness and metabolic syndrome risk factors in obese middle age women.

This study analyzed a 3D hydrodynamic advection diffusion using the EFDC model (Environmental Fluid Dynamics Code) in the agriculture lake to prevent stratification when we install a water circulator. EFDC model was predicted the range of the water circulator and various operational parameters ware derived for minimize the impact of the internal lake. Through EFDC simulation, water circulation is started overall circulation after 30days and a lake overall circulation showed that it was possible operated the water circulator after about 100days. Also, advection diffusion concentration was low in a lake when water circulator operate intermittent condition than continuous condition. And the entire circulation was stable in this condition. The S/B (Surface/Bottom) ratio can reduce the impact of lake as the surface water mixing a lot of. When the same condition (S/B ratio(3:1)), Case 8 (50days operation: 50days stop) of condition were able to minimize the impact of lake.

A theoretical study on the ground water flow adjacent to buried pipe was conducted. Incompressible and irrotational flow were considered in analytical study. Ground water flow were defined by complex potentials. Firstly, uniform flow without buried pipe was analysed and then the effect of buried pipe was considered by superposition via circle theorem. Although two kinds of flow can be added by linearity of complex potentials, investigation of the singularities of the complex potentials should be done in advance. Finally, ground water flow past a buried pipe was analysed via complex potentials and net force exerted on the buried pipe by the ground water flowing past with circulation was derived.
