Objectives : To propose the referential data to evaluate the health impacts of Vietnam veterans' children whose father were exposed to herbicides in Vietnam War. Methods : Vietnam veterans who visited to Pusan Veteran Hospital for medical care were recruited from April to October, 1998. They were 71 and asked about their own combat history, symptoms and illness, and health status of their 182 children. The informations were collected by direct and phone interview. Exposure estimation was also performed as exposure score depending on year and unit of participation, and personal episodes related to exposure to herbicide in the war. It classified into three groups; lower(<18.0), moderate(18-53), high$(\geq53)$ exposure group. Results : The mean age and the period into the combat of the veterans were 52.8 years and 15.0 months. The mean exposure score was $18.1{\pm}9.9$, and mainly distributed in lower (46.5%) and moderate(52.1%) exposure group. Most(90.1%) of them were diagnosed as sequelae(21 cases) and suspected sequelae(43 cases) of the herbicides by Korean veteran's hospital diagnostic criteria. The major sequelae was peripheral neuropathy 13 cases, chloracne 5 cases, and the major suspected sequelae was hypertension 20 cases, diabetes mellitus 18 cases, liver disease 12 cases, central neuropathy 11 cases, etc. About birth, 42.2% and 16.9% experienced spontaneous abortion and stillbirth, respectively. The mean exposure score was higher in stillbirth experience group(p<0.05). About half of the children(90 cases, 49.5%) hold the abnormal health status: those were skin pigmentation 38 cases, rash 23 cases, congenital anomaly 15 cases, general weakness 12 cases, purpura 8 cases, visual disturbance 8 cases, etc. These health problems had no association with father's exposure level(p>0.05). Conclusions : These results were depend on their own answers, and expectation for compensation did not excluded, therefore, this study may have limitations: inaccuracy of informations due to recall bias and response bias. Nevertheless, through this study, we could image the fundamental aspect for health impacts of Vietnam veterans' children for preparing the national control program and policy. A large scale epidemiologic study with valid exposure assessment on the health impacts of Vietnam veterans' children is recommneded.

하천복원과 환경유량을 위한 기초자료를 확립하고자 금강수계의 초강천에서 생물학적 건강성 및 최적 생태유량에 대하여 조사하였다. 출현한 어종은 총 9과 36종 4,669개체였으며, 잉어과가 66.7%(24종)로 가장 높았다. 참갈겨니가 1,588개체로 34.0%로 우점종이었으며, 아우점종은 피라미로 22.6%, 우세종은 쉬리 13.3%로 나타났다. IBI와 QHEI는 상류로부터 하류로 내려갈수록 값이 감소하는 것으로 나타났으며, IBI 값은 27.9~38.6으로 평균 32.2로 양호상태를 나타냈다. 참갈겨니, 쉬리 및 감돌고기에 대하여 서식도적합도지수(HSI) 및 최적 생태유량을 산정하였다. 참갈겨니의 경우, 유속과 수심의 HSI 값은 각각 0.1~0.4 m/s와 0.2~0.4 m 였다. 감돌고기는 유속이 0.2~0.5 m/s, 수심이 0.4~0.6 m 및 하상재료가 가는자갈~호박돌로 나타났다. 이를 기초로 하여 각 지점의 최적 생태유량은 하류로 내려갈수록 값이 증가하는 것으로 나타났으며, 이에 따라서 WUA 값도 증가하는 것으로 나타났다.
