National Geographic Information Institute has installed the first permanent Global Positioning System (GPS) station SUWN in 1995 and, as of today, the number of sites is 14. In this study, we visited all the 14 stations and determined if the site mount and antenna configuration conforms to the international site guidelines published by International GNSS Service and National Geodetic Survey. The environment around each station was also checked for the possibility of causing positioning errors. In addition, the GPS data quality was evaluated using the quality-checking program called TEQC. As a result of site visits, we found that low stations (TABK, CHJU, KWNJ, and WNJU) have unfavorable environment and TEQC results validated it. TEQC results also showed that the GPS receiver change during years 2005-2006 reduced the multipath errors and the number of cycle slips at every station.

This study is to suggest some developmental policies by analyzing the activities of first aid party in Kwangju and Chonnam regions for two years from Jan. 1, 1991 to the end of December, 1995. First, the residents in Kwangju and Chonnam regions have the sufficient benefits of emergency medical center, but it will be desirable that general hospital should be established and managed in Kohung peninsula which forms the wide island area far away from big cities. Second, the classification of the degree of severe case in the field by rescue members should be strengthened as the means which can reduce the number of patients transferred to the emergency room and the legal method which rescue members can select the medical agency. Third, children less than 10 are most frequent emergent patients and it is due to parent's indifference and children's in sensibility to safety. So the safely education in the course of infant and elementary education should be strengthened and the method which can keep the self safety through the legal system. Fourth, to increase the rate of emergency measure by rescue members, the reasons of fail of emergency treatment are suggested, the treatment results of each rescue member are analyzed every year and it is desirable that the system which can evaluate the personal ability should be introduced. Fifth, the medical accidents occurred in the case of medical act, by rescue members must lake the legal responsibility, but such a problem can he solved with the compensation of insurance system by government. Sixth, to reduce the time required for transfer, traveling service system for the fixed period in beach should be complemented and extended more and service system at ordinary times should be examined at mountains, the area of traffic jams and large special industrial park. Seventh, since service system with one team of two members of 119 rescue party in expressway cannot be mobilized when multiple accidents occur at the same time, it is considered that service system of two teams of four members should be extended. Eighth, first-aid service in expressway is conducted with rescue and emergency treatment by the rescue party at the same time, but the professional rescue lacks and it may result in the injury of patients. Therefore the creation of rescue party in expressway is the urgent problem.

저영향개발(LID, Low Impact Development)은 물순환체계 개선을 위해 녹색 공간의 확보, 자연형 공간 조성, 자연상태의 수문순환 기능의 유지 기법 등을 활용한 개발 대상지에서의 강우유출 및 비점오염원의 영향을 최소화할 수 있는 새로운 방법이다. LID는 강우 유출수의 지하침투, 강우 종료시 증발산량의 확보, 강우 유출수의 재이용 등을 통한 강우 유출량을 최소화하는 것에 그 목적이 있다. LID 방법은 우수저류 공원, 생태저류지, 지붕층 저류공원, 보도 저류공간, 인공습지, 완충녹지대, 수목 보존지대, 지붕층 배수관, 강우 저장조, 투수성 포장, 토양 개량, 불투수층 최소화, 비점오염원 저감 등으로 효율성, 경제성, 유연성, 합리성, 토지 가치증대 등의 장점이 있다. 영산강 수계의 BOD 배출부하량이 점오염원(21,019kg/일)과 비점오염원(50,047kg/일)의 비율이 3:7 로 비점오염원 배출부하량이 훨씬 큰 상태이다. 특히, 광주광역시, 농업용 토지, 축산계 등의 비점오염원이 영산강 수질에 크게 영향을 미치고 있다. 따라서 본 연구에서는 비점오염원의 영향이 큰 영산강 수계를 대상으로 앞으로 이루어지는 개발계획을 분석하여 LID 기법을 적용하였을 때 영산강 수질에 미치는 영향을 모델링을 통해 예측하고자 한다. 수질개선에 어느 정도의 효과가 있는지 검증하기 위해 국내 실정에 맞고 QUAL2E 모델을 근간으로 WASP5 모형의 장점들을 접목시켜 Bottle BOD의 반응기작 및 조류의 생산에 의한 유기물 증가, 탈질화 반응 등 정체수역에서 일어날 수 있는 반응기작을 모의할 수 있도록 보완한 QUALKO2 모형을 이용하여 그 효과를 모의하고자 한다. 본 연구를 통해 LID 기법이 도시화에 영향을 얼마나 덜 주는지, 수계의 비점오염원 효과를 통해 물순환 체계의 개선이 어느 정도로 어루어지는지에 대한 효과를 검증을 할 수 있는 계기가 될 수 있을 것으로 판단된다.

최근 한강, 낙동강, 금강, 영산강 등 주요 하천에 설치된 다기능 보는 평수위 및 홍수위의 수위차를 상당히 감소시켰으며, 가동보 운영으로 홍수초기 일정기간동안 수위를 조절할 수 있으므로 친수 목적으로 활용할 수 있는 고수부지 공간과 보로 인하여 유지되는 수면공간 등 새로운 가치를 창출할 수 있는 하천공간이 조성되었다. 새롭게 펼쳐진 하천공간을 다양한 여가 및 문화활동 공간으로 이용하고자 하는 국민적 요구가 증가함에 따라 공원 캠핑장 자전거도로 등 하천내 친수지구를 안전하게 관리해야할 필요성 또한 증가되었으므로, 본 연구에서는 영산강 친수지구를 대상으로 침수예측 현황 및 개선방안을 검토하였다. 지금까지의 국내 하천 홍수관리 정책은 하천의 홍수피해로부터 하천변 저지대의 범람피해를 최소화하는 방향으로 추진되었다. 이에 따라 홍수예보 또한 홍수주의보, 홍수경보 등 비교적 규모가 큰 홍수를 대상으로 사전에 예측하여 발령함으로써 홍수피해를 대비하는 것이 목적이었다. 그러나 하천 친수지구 침수는 지금까지의 홍수예보와는 대상홍수 유량규모에서부터 큰 차이를 나타낸다. 본 연구에서는 친수지구 지형 반영 개선, 지류 유입량의 민감도 분석을 통한 주요 지류유입 유량의 정확도 개선, 다기능 보 운영에 따른 보 배수영향의 반영 등을 통하여 현재 국토교통부의 홍수예측 모형인 FLDWAV 모형의 홍수위 예측 정확도를 개선하였다. 그 결과, 황룡강 합류 상류구간과 하류구간 모두 침수시작 시점의 포착, 수위수문 곡선의 형태 등 다양한 관점에서 수위해석의 정확도가 개선되었다. 삼지 지점의 경우, 홍수초기 수위해석 오차가 크게 줄어서 RMSE가 1.33m에서 0.30m 홍수해석 정확도가 개선되었으며, 광주지점의 경우의 RMSE는 1.60m에서 0.56m로 개선되었다. 황룡강 합류 하류 지점인 본동과 나주지점의 RMSE는 각각 0.30m, 0.39m에서 0.02m, 0.42m로 수정되었으며, 나주지점의 경우 저유량 규모에서 모형의 보정이 좀 더 수행될 필요가 있음을 확인하였으나 침수시점의 포착(본동 7.8 EL.m, 나주 4.0 ELm)에서 크게 개선됨을 확인하였다.

As the spread of DC power distribution systems increases, the occurrence of failures and fire accidents are also increasing. In particular, the ESS fire accident, which is a component of the smart grid, and the fire accident of the solar power system, which is a direct current system, are caused by problems in the electrical connection between system components as the supply of new and renewable energy rapidly increases and old facilities increase. An arc that can cause a direct fire by releasing the induced light and heat has been pointed out as one of the causes of fire. Therefore, the problem of such an arc defect is that it is impossible to block an arc accident in advance with the existing overcurrent circuit breaker and earth leakage circuit breaker. In this paper, we intend to develop a test equipment that satisfies international standardization and to develop a DC arc generator to protect against failure and fire caused by arcing.

Background: In this study, the importance of constipation and back pain was assessed by regression analysis of the effects of stress, dietary habits, and water intake on constipation in women in their twenties and the influence of constipation and body mass index (BMI) To provide basic data. Methods: This study selected 109 having constipation of 120 students attending G University in Gwangju and eating habits, water intake level, stress and BMI. Trigger point at the tip of erector spina was palated with tenderness set in order to examine whether muscle tenderness and actual low back muscle tenderness level were same and left and right parts were measured three times and average of Max values was used. We examined the effect of constipation on low back pain and examined constipation and BMI to determine whether they affected low back pain. Results: There was no significant difference in eating habit although there was a significant difference in the effect of stress and water intake on constipation. Constipation had significant difference in back pain. However, there was no significant difference in BMI, normal weight, overweight, and obesity except for low body weight. Conclusions: This study found that constipation was associated with stress levels, water intake, and back pain. In conclusion, this study suggests basic data to prevent and treat constipation-related back pain, and recommends plenty of water intake, proper exercise and stress management to prevent constipation.
