The characteristics of agricultural water rights in multi-purpose dams in Korea was examined. The river system with multi-purpose dams can be divided into national river system and WRC(Water Resources Corporation) river system according to ownership of dam use rights. While the national river system have permitted water rights, the WRC river system have vest water rights and contract water rights. The two river systems have different characteristics of agricultural water rights, and therefore the water right of two system need to be unified. It is also known that water release from multi-purpose dams against water demand does not satisfy agricultural water rights.

In this paper, we presented the exact Riemann solver for the air-water two-phase shock tube problems where the strength of the propagated sock wave is moderately weak. The shock tube has a diaphragm in the middle which separates water medium in the left and air medium in the right. By rupturing the diaphragm, various waves such as rarefaction wave, shock wave and contact discontinuity are propagated into water and air. Both fluids are treated as compressible, with the linearized equations of state. We used the isentropic relations for the air and water assuming a weak shock wave. We solved the shock tube problem considering a high pressure in the water and a low pressure in the air. The numerical results cleary showed a left-traveling rarefaction wave in the water, a right-traveling shock wave in the air, and the right-traveling material interface.

The characteristics of agricultural water rights were examined for the national rivers in Korea. We suggest that the national rivers could according to the actual management organization of agricultural water right be categorized into national management rivers KOWACO(Korea Agrcultural & Rural Infrastructure COrporation) management river. The agricultural water right between the national and KOWACO management rivers have different characteristics for irrigation period permit procedure water charge and type of water right. The agricultural water rights are granted in the natural discharge less than reference droughty discharge for most of national management rivers and in the developed discharge for the KOWACO and KARICO management rivers. The current system of agricultural water rights is complicated inconsistent and incapable of coping with unusual drought and therefore it needs to be improved.

The concrete pipe used to distribute irrigation water to the right place now available is commonly made up of cement , sand, earth, pebble, etc. These materials with right ratio and right amount of water were mixed and squeezed through the pipe-making machine called vertical squeezed pipe-making machine, and then a cement prefabricated pipe is produced . This kinds of pipe has been expanding by leaps and bounds. Being little cement contents and low cost, the length of pipe is 1.0m or so with weight of 50kg, which is easy to be made and to be transported. The demolish pressure of it is 0.2 MPa or so, which meets the needs of agriculture irrigation . The buried pipe irrigation system, has been popularized in Jining Municipal , Shandong Province. By the year of 1995 , the irrigation area under pipe conveyancesystem usign this type of pipe has reached 74000 hectares. By calculation, about 27.7million ㎥ water, 2.88 million kWh power , 0.167 million man power and 1528 hectares cu tivated land will be saved one year, adding value of agriculture output increased by 10 million kg. The total economic benefits amount to 0.92 million US$ a year. The paper presents the pipe making course and its application on a large scale area.

본 연구의 목적은 삽교천 유역에서 하천수 사용 허가량 뿐만 아니라 허가이외 수리권을 모두 고려한 시공간적 물부족을 분석하는 것이다. 분석 결과, 전체 용수이용량 중 농업용수 이용량은 98%를 차지하고 있으며, 이중 허가이외 농업용수의 비율이 83%로 해당유역에서 농업용수가 차지하는 비율이 매우 높은 것으로 나타났다. 2001~2011년간의 물수급에서는 삽교천 16개 표준유역 중 곡교천 상류에서만 물부족이 예측되었으며, 2009년 관개기 농업용수 사용으로 인한 물부족량이 가장 많은 것으로 분석되었다. 특히 강수량이 부족하고 이앙용수가 많이 사용되는 4~5월에 집중되는 것으로 나타났다. 그러나 허가이외 수리권을 제외하였을 경우에는 물부족이 발생하지 않아, 허가이외 수리권 관리의 시급함을 알 수 있다.

Objective : The purpose of this study was to evaluate water distribution differences of the right and left low limb in patients who had low back pain with sciatica or not. Methods : Water distribution differences of the right and left low limb by body composition(INBODY 2.0, Biospace, seoul, korea) were analysed in the views of groups(low back pain with and without sciatica) and duration of disease. Results : 1. In the case of low back pain patient, there was no significance in variance of water distribution of the right and left lower limbs regardless of suffering period, but significance difference in patients that have suffered low back pain with one side sciatica showed according to suffering period. 2. Within 2 weeks, there was no significant deflection between low back pain with and without sciatica in water distribution of the right and left lower limbs, More than 2 weeks significant deflection showed. Conclusion : Loss of lower limb's muscle that ensue in contracting a disease period was observed in Low Back Pain with Sciatica. The continuos studies about pathological change of lower limb in low back pain have to be perfomed.

This study, regarding curved channel, was performed to compare and analyze hydraulic characteristics and the speed of water and water level for left bank and right bank through hydraulic model experiments and numerical analysis. Real channels that had characteristics of curved channel were selected as objectives. In order to easily operate one and two dimensional numerical analysis and comparison for total 2.4Km model channel, measuring point was set up as 200m. HEC-RAS model was applied as one dimensional numerical analysis program and SMS model was used as two dimensional numerical analysis program. In respect of speed of water, the average speed of water for right bank recorded 8.33m/s in a model experiment and 3.08m/s, 8.57m/s were average speed of water for right bank in one dimensional and two dimensional numerical analysis. The average speed of water of two dimensional numerical analysis was quite similar to that of model experiments. Also, as for water level, maximum observational errors between one and two dimensional numerical analysis for right and left bank of model experiments were 0.66m, 0.84m and 0.28m, 0.48m for each. It was found that two dimensional numerical analysis had a similar result to hydraulic model experiments. Accordingly, from the result of this study, two dimensional numerical analysis should be used rather than one dimensional numerical analysis, when numerical analysis for curved channel is conducted.

We could summerize the concept of the right and left mentioned in Nai-Gyung and some literature of oriental medicine as follow At first the right and left is a directional right and left which implys left-liver-right-lung(左肝右肺), left-yang-right-eum(左陽右陰), secondly it is also the road of eumyang which implys man-left-woman-right(男左女右), left-blood-right-ki(左血右氣), left-sinsu-right-myungmon(左腎水右命門), and left-right of pulse. left-liver-right-lung(左肝右肺), left-yang-right-eum(左陽右陰) and man-left-woman-right(男左女右) are expressions of the movement of yang which is a core of chang, at the same time, left-blood-right-ki(左血右氣), left-sinsu-right-myungmon(左腎水右命門), and left-right of pulse are expressions of the eum in response to the movement of yang. (go up and down of water and fire) Finally, both a directional right and left and a road of eumyang mean a road of going up and down of eumyang so, this is very important index in circulation and keeping ballance of eumyang (ki-Hyul:氣血) in the human body therefore, we can treat a disease with acupuncture in the use of this charater, for example when a disease occurs in the left side, we can treat it with acupuncture in the right side, the same applys to right.

Built-out issue of copper processing appearing recently in the Paldang watershed is a critical problem to deteriorate the basic framework of national water management policy as well as to be simply a copper-related problem. Up to now, Korea government has invested hard and relevant upstream areas have been victimized readily in a variety of field to comply its goal of 'Safe Water Supply'. Because of the reason, the desirable water quality level of the Paldang watershed has been maintained regardless of its dense population. Paldang drinking water management policy is based on residents' understanding which is considered as a 'social capital'. The issue raised in the aspect of water quality management policy should be reviewed on the basis of the 'social capital' concept. One regarding semiconductor industry as a potential industry to export many products in 10 years insists that the industry not be a simple private business but be a prominent part for national competitiveness. There is no doubt about this opinion. However, a nation should support environmental right-to-life of its people prior to any other tasks. In other words, it is really risky to give up people's right due to economic benefits. Therefore, it should not happen to trade 'life', the dignity of man, with national competitiveness which is likely to be preferred in these days. In addition, coherent policy not to destroy 'social capital' promoting Paldang drinking water resource management policy should be maintained.
