본 연구에서는 인체 내에서 방사성핵종의 거동에 관하여 국제방사선방호위원회에서 권고한 최근 호흡기 모델, 소화기 모델 및 생체동역학 모델을 사용하여 생물학적분석 자료로부터 섭취량과 예탁유효선량을 평가하기 위한 BIDAS 프로그램을 개발하였다. 프로그램은 생물학적분석 자료를 관리하는 데이터베이스 모듈, 각 방사성 핵종에 대한 예측 생물학적분석 양을 내장하고 있는 모듈, 측정된 생물학적분석 양에 근거하여 급성 및 만성 피폭으로부터 섭취량과 선량을 평가하는 계산모듈 등으로 구성되어 있다. 본 논문은 프로그램의 특성과 검증결과에 대해 기술한다.

방사성핵종의 특성, 섭취형태 그리고 내부피폭 감시주기는 작업자의 방사성핵종 섭취량 및 내부피폭선량 평가 결과에 중요한 영향을 줄 수 있다. 따라서 방사성핵종이 흡입섭취 될 경우 섭취형태(급성 또는 만성) 및 내부피폭 감시주기에 따른 섭취량 평가 오차를 계산하였다. 섭취 핵종으로는 /I(Type F), Cs(Type F), U(Type M, Type S)를 고려하였고, 방사능입자크기(AMAD)는 1 와 5 를 고려하였다. 섭취형태에 따라 평가된 섭취량의 상대오차는 방사성핵종, 흡수형태 그리고 내부피폭 감시주기에 따라 달랐으나, 입자크기에 의한 영향은 거의 없었다. 섭취형태 가정에 따른 섭취량 평가 오차를 10% 미만으로 줄일 수 있는 내부피폭 최대감시주기는 /I(Type F)에 대해 60일, Cs(Type F)에 대해 180일, U(Type M)에 대해 90일, 그리고 U(Type S)에 대해 360일로 나타났다.

공급수가 원판틀형 모듈에 잘 분포될 수 있는 역삼투형 하우징(HY)을 개발하여 설계 제작하였으며 상용화된 Rochem(RC)시스템과 투과성능을 비교하였다. 자체 개발한 HY시스템은 RC시스템에 비하여 투과유속이 약간 떨어지는 반면, NaCl 배제율은 전반적으로 높았다 원판틀형 모듈인 type A, B, C에 대한 투과유속 및 배제율을 NaCl, sucrose 및 butanol 수용액으로 측정하였다. NaCl 및 sucrose의 경우, type C, A, B의 순으로 투과성능이 우수하였으나 butanol의 경우는 type B, C, A 순이었다. Type A에 대한 type C의 butanol 투과유속은 농도가 감소할수록 그리고 28 bar 범위내에서 운전압력이 증가할수록 향상되었다.

Many higher fungi were collected at Mt.Sunun, Mt.Kangchon and Mt.Moak from June, 1991 to April, 2003. They were identified and surveyed with references. According to the result, Cordyceps clavata, C. cocciniocapite, C. ryougamimontanna, C. tuberculate J. moelleri and C. yakushimensis are unrecorded species to Korea. They were designed Korean common names by authors. Common names: Cordyceps clavata, C. cocciniocapite, C. ryougamimontanna, C. tuberculate f moelleri, C. yakushimensis, unrecorded species, common names.

This study was carried out obtain basic information for growth characteristics by different age of Dendropanax morbifera in chonnam, such as Yosu, Sunchon, Haenam, Gangjin, Wando. The pH of soil in cultivation area was 5.2 to 5.6 and organic matter was very high up to 10.6% . P205 content of soil in cultivation area was 35.3 to 42.1 mg/L, C.E.S was 13.9 to 14.4 me/100g, and moisture rate was 19.2 to 21.1 % . The flowering of Dendropanax morbifera began from 6~7 years old tree. The flowering date was at 10th of July at Wando. The growth characteristics of 12 years old tree was 929.5cm in stem height, 134.1mm in stem diameter, and 15 years old tree was 1,117.9cm in stem height, 160.8mm in stem diameter. The number of leaf was 13.9 at five years old tree, and the petioles length was 12.6 at five years old tree. Xylem sap can be had at more than 10 years old tree with good growth more than 10 em stem diameter.

Many ascomycetes were collected at Mt. Minjuji, Mt. Manduck, Mt. Odae, Mt. Yonsuk and Mt. Sunun from August 1999 to September 2000. They were identified. According to the reusulting, Helvella villosa (Hedw.: O. Kuntze) Dissing and Nannfedt, Dasychyphus corticalis (Pers.:Fr.) Mass., Lachnellula fuscosanguinea(Rhem) Dennis, Lachnellula subtilissima (Cke.) Dennis and Scutellina erinaceus (Schw.) Kunrze are newly to Korea. They were designed Korean common names by authors.

Narcotic drugs generally refer to serious and habitual hidden rash such as opium, heroin, methyphetamin, nabinol, cocaine, and so forth. At present, narcotic drugs are spread unchecked and are causing a big social problem. So many countries and narcotists are making every effort to set up a barricade against narcotic drugs. And there is a limit suitable treatment for them. Thus Tuo Yin Tang Jiang is developed. As indicated by Chinese letters, Tuo Yin Tang Jiang(TYTJ) is a crude drug. It is a traditional chinese medicine developed by the study done from June in 1998 to June in 1999 that Hubeisheng was entrusted with by People's Republic of China. This study is a treatise on etiology and syntomatology of narcotism. TYTJ is a medicine which is in accord with Pharmacopeia of the People's Republic of Chinal) in order to remove from the body the toxic materials resulting from narcotic drugs such as opium and heroin. According to the standard diagnosis on narcotism, 105 cases are studied and treated at the Rehabilitation Center attached to Enshi Autonomous Region Hospital in Hubeisheng. 105 cases are divided into 2 groups by double-blind method. One is the experimental group which has 56 cases. The other is the control group which has 49 ones.13 cases among 105 cases are addicted by intravenously injections. 9 cases are by oral takings. It took 10 days for this experiment to be performed. Two groups didn't show a striking individual variation based on the age, gender, period of taking drugs, withdrawal symptoms, complication, and state of health. The experimental group had a higher effect of treatment than the control group had. TYTJ treats diseases effectively and has no side effect, irrespective of the serious or slight addiction to opium and morphine.
