본 연구는 팔당댐 상류부(충주댐$\sim$팔당댐 구간)의 수리학적 홍수예측 모형 구축시 한강본류 내에 위치하고 있는 충주조정지댐을 고려하는 모의 방안을 제시하였다. 충주조정지댐은 특정 유입량 이하일 경우 일정하게 수위를 유지하며 그 규모 이상의 홍수에서는 모든 문비의 개방이 이루어지기 때문에 이러한 운영특성을 수리학적 홍수예측 모형에 반영하는 것은 어려움이 따른다. 따라서 본 연구에서는 충주조정지댐 운영특성을 수리학적 홍수예측시 반영할 수 있도록 수문을 완전히 개방하는 시점을 기준으로 2단계의 수위-방류량 관계를 적용하는 방안을 검토하였다. 먼저 2단계 수위-방류량 관계의 작성을 위하여 1990년$\sim$2008년까지의 17개 홍수사상에 대한 충주조정지댐의 운영시계열 자료를 분석하여 기준 방류량을 설정하였으며 기준방류량 이하일 경우 일정하게 수위가 유지되는 수위-방류량관계 곡선을 내부경계조건으로 이용하고, 기준방류량을 초과할 경우 수문 개방시 관측된 저수위와 방류량 자료를 토대로 작성된 수위-방류량관계를 이용하는 방안을 제시하였다.

최근 국내에서 저해상도 위성영상을 이용한 적설 분포의 추출연구가 융설과 관련된 수문학적 연구에 이용되기 시작하였다. 한반도와 같이 넓은 지역을 대상으로 추출하는 과정에서 대기에 의한 방해가 너무 큰 영상은 구름 아래 지표면의 정보를 얻을 방법이 없어 해당 날짜의 영상을 제외 할 수밖에 없는 문제가 생긴다. 본 연구에서는 센서의 특성과 영상의 촬영 시간, 그리고 촬영 각도가 달라 서로 다른 대기의 영향을 받는 Terra MODIS 위성영상과 NOAA AVHRR 위성영상을 이용하여 각각의 적설 분포를 추출하는 방법을 비교 연구함으로써 영상을 분석하는데 있어 구름의 영향을 최소화 하고자 하였다. 2004년부터 2006년까지 겨울철의 적설이 발생한 기간을 대상으로 총 3개년의 영상을 분석한 결과를 바탕으로 두 영상으로부터 추출된 적설분포의 차이를 우리나라의 충주댐 유역을 중심으로 비교하였다. 밴드별 파장대의 반사 특성을 이용한 MODIS snow cover와 임계값을 선정하여 구하는 NOAA AVHRR는 서로 다른 적설분포를 보였다고 판단되며, 이는 해상도와 영상 합성, snow cover 추출 알고리즘의 차이 및 대기 현상의 영향 등으로 인하여 추출면적 값이 차이를 보이는 것이라 생각된다. 두 영상에 의한 추출면적의 비교분석 결과, 적설분포의 추출에 있어서 두 영상을 서로 절충하여 사용할 수 있다고 판단된다.

The following case studies illustrate the application of oriental medical treatment of patients diagnosed with neurogenical bladder. The outstanding symptoms of two cases were general weakening and voiding difficulty, urinary retention and lack of urine sense. In one case, neurogenical bladder was caused by an operation on the femur, and in the other case, by diabetes and anemia. Western medical treatment didnot have any effect in these cases, but after oriental medical treatment, self-voiding was possible. These resu1t suggest that oriental treatment should be considered for patients with neurogenical bladder.

The objective of this study was to assess the variation in the concentration of assimilable organic carbon (AOC) in a drinking water resource, and investigate the characteristics of AOC derived from algae. The seasonal change in AOC at the Kamafusa dam corresponded to changes in the algal cell number. In order to understand the relationship between AOC and algae in a water resource and water purification plant, two kinds of laboratory experiment were performed. The algal culture experiment showed that extracellular organic matter (EOM) that was released during the growth of Phormidium tenue with M-11 medium led to significant increases in the AOC concentration, but no significant variation in the AOC concentration was observed with CT medium containing a high dissolved organic carbon concentration. The chlorination experiment showed that the AOC included in EOM was not easily removed by chlorination, although the AOC included in intercellular organic matter released from the algal cells by chlorination was removed under conditions where residual chlorine was detected.

I. Introduction The essence of Oriental medicine consists of ancient books, experienced doctors and succeeded skills of common society. Many famous doctors studied medical science by their fathers or teachers. So the history of medical science is long. $\ll$DangDaeMyeongIImJeungJeongHwa(當代名醫臨證精華)$\gg$ written by SaWoogWang(史宇廣) and DanSeoGeon(單書健) has many medical experience of famous doctors. So it has important historical value. Bi(痺) means blocking. BiJeung is one kind of symptoms making muscles, bones and jonts feel pain, numbness or edema. For example it can be gout or SLE etc. So I studied ${\ll}BiJeungJuJip{\gg}$. II. Final Decision Following decisions of Chinese doctors of 20th century are as follows ; 1. JuYangChun(朱良春) emphasized on IkSinJangDok(益腎壯督) to treat BiJeong. And he devided WanBi(頑痺) as PungHanSeup(風寒濕), DamEo(痰瘀), YeolDok(熱毒), SinHeo(腎虛). He used insects for medicine. 2. ChoSuDoek(焦樹德) introduced past prescription. He used ChiBiTang(治痺湯) to treat HaengBi(行痺), TongBi(痛痺), ChakBi(着痺). He insisted that Han(寒; coldness) and Seup(濕; dampness) be Eum(陰) and Pung(風; wind) can change his character to be Eum. After all BiJeung is usually EumJeung. So he used GaeJi(桂枝) and BuJa(附子). By the way he used ChungYeolSanBiTang(淸熱散痺湯) for YeolBi, BoSinGeoHanChiWangTang SaBok(王士福) emphasized on the importance of medicine. He introduced many treatments like CheongYeol(情熱) for YeolBi and YiO(二烏) for HanBi. And he divided BiJeung period for three steps. At 1st step, we must use GeoSa(祛邪), at 2nd step, we must use BuJeong(扶正) and at 3rd step, we must use BoHyeol(補血), he insisted. And he introduced many herbs to treat BiJeung. 4. JeongGwangJeok(丁光迪) said that GaeJi(桂枝), MaHwang(麻黃), OYak(烏蘖) and BuJa(附子) are very important for TongRak(通絡). And pain usually results from Han(寒), so he liked to use hot-character herbs. 5. MaGi(馬志) insisted that BiJeung usually result from ChilJeong(七情). And he liked to use insects for treatment of BiJeung. 6. WeolSeokMu(越錫武) introduced 8 kinds of treatments and divided BiJeung period. Also he divided BeJeung for PungBi(風痺), HanBi(寒痺) and SeupBi(濕痺). 7. SeoGeaHam(徐季含) observed many patients and concluded that 86.7% of BiJeung is HeuJeung(虛症). 8. YuJiMyeong(劉志明) said that YeolBi is important and CheongYeol is also important. So he emphasized on DangGyuiJeomTongTang(當歸拈痛湯) and SeonBiTang(宣痺湯). 9. WangLiChu(汪履秋) studied cause of WanBi. Internal cause is GiHyeolHeo(氣血虛) and GanSinHeo(肝腎虛) and external cause is SaGi(邪氣) he insisted. 10. WangSaSang(王士相) said that YeolBi can be SeupYeolBi or EumHeuYeolBi(陰虛熱痺) and HanSeupBi(寒濕痺) is rare. He use WooBangJaSan(牛蒡子散) and BangPungHwan(防風丸) for SeupYeolBi, DangGyuiSaYeokTang(當歸四逆湯) for HanSeupBi. 11. JinTaekGang(陳澤江) treated YeolBi with BaekHoGaGyeJiTang(自虎加桂枝湯) and SaMyoSan(四妙散). If they don't have effect, he tried to cure BiJeung step by step. And he used e term of GeunBi(筋痺) and BangGiMogwaEIInTang(防己木瓜薏苡仁湯) was good for GeunBi. 12. MaSeoJeong(麻瑞亭) said that PungSeupYeokJeul(風濕歷節) is BiJeung and it is related to GanBinSin(肝脾腎; liver, Spleen, Kindey). And he emphasized on balance WiGi(衛氣) and YoungHeul(營血). 13. SaJeJu(史濟桂) said that GeunGolBi(筋骨痺) is similar to arthritis and sometimes called ChakBi. And SinBi(腎痺) is terminal stage of ChakBi, he said. He also used insects for treatment. 14. JeongJeNam(丁濟南) tried to cure SLE and used GyeJi, CheonCho(川椒), SinGeunCho(伸筋草), SunRyeongBi(仙靈脾), HyconSam(玄蔘) and GamCho(甘草). 15. JinGYungHwa(陳景和) emphasized on diagnosis of tongue. If the color of tongue is blue, it usually has EoHyeol(瘀血), for example. And he also used insects. 16. JuSongI(朱松毅) tried to devide YeolBi with OnByeong(溫病), Wi(衛), Gi(氣) and Hyeol(血). 17. RuDaBong(蔞多峰) said that JyeongHeo(正虛), OiSa(外邪) and EoHyeol are closely related. And he explained BiJeung by deviding the body into the part, for example head, neck, shoulder, waist, upper limb and lower limb. 18. YuMuBo(劉茂甫) defined PungHanSyubBi as chronic stage and YeolBi as acute stage.

This paper not only aims to establish a plan to acquire the water stage data in a constant and proper manner by using limited manpower and costs, but also establishes the fundamental technology for acquiring the water level observation data or the stage data. For this, this paper focuses on how to acquire the stage data, in a uniform manner, that can represent each basin by developing the technology for establishing the optimal observational network. For that, this paper identifies the current status of the stage gauge stations installed in the ChungJu dam including wetland basin mainly along the national rivers. Then, thus obtained factors are used to develop the representative unit hydrograph. After that, the data are converted into the probability density function. Then, the stations are calculated information transfer amount. As a last step, we establish the optimized stage gauge network by the location of the stage station and space impact that takes into account for the combinations of the number of the stations. In other words, we consider the combination of the stage gauge station with information transfer amount and spatial correlation analysis for estimation.

In this study, there has been investigated the simulation of irradiation dose using Monte Carlo methodology and experimental substantiation for the biological control of wooden cultural property. In the evaluation of fungal contamination on wooden cultural property, Dongyae, from exhibition storage, Aureobasidium pullulans was mainly identified. But these microorganisms were completely inactivated by 20 kGy gamma irradiation. For dosimetry simulation of Dongyae, Monte Carlo methodology with MCNP was used. The real dosimetry was measured using alanin dosimeters (at 7 different points on the front plan and 7 points on the back plan). Simulated and experimental results are compared and good agreement is observed. These result shows that irradiation can offer biologic control of wooden cultural property by optimal irradiation dose through high penetration power and Monte Carlo simulation.
