본 연구에서는 최적관리기법(BMP)을 실제 영농지역에 보급하여, 광역단위 논에서 발생하는 비점오염물질의 저감효과를 분석하고자 하였다. 현재까지 선행 연구들을 통해 다양한 BMP 효과 검증이 이루어졌으나, 실제 영농지역 농민들에게 BMP를 보급하여 그 효과를 측정한 연구는 부족한 실정이다. 이에 본 연구에서는 광역단위 논 지역을 대상으로 물관리기술(물꼬)과 시비관리기술(완효성 비료)을 보급하고 강우시와 비강우 모니터링을 통해 BMP 효과를 측정하였다. 연구 대상지구는 전라북도 부안군 백산면 용계리 일대로 새만금 지역에 위치하여 있다. BMP 보급 효과를 분석하기 위하여 먼저 참여농민과 농지를 선정하였으며, 관개지역과 배수면적을 구분하여 모니터링 조사 지점을 선정하였다. 연구대상지구는 SO#1(완효성 비료 95%, 비참여 농가 5%), SO#2(완효성 비료2%, 물꼬 8%, 완효성비료 + 물꼬 40%), SO#M(완효성 비료 96%, 비 참여 농가 4%) 총 3개의 배출구로 구분하였다. 각 지구별 오염부하량을 측정한 결과, 대조구 대비 SO#1에서는 수질항목별로 10.6 ∼ 85.5%, SO#2는 8.1 ∼ 45.9%, SO#M은 10.7 ∼ 86.2%의 범위로 저감된 것으로 분석되었다. 특히, SS의 단위면적당 오염부하 저감율이 가장 큰 것으로 나타났으며, TOC의 단위 면적당 오염부하 저감율은 가장 작은 것으로 나타났다. 하지만 본 연구 결과는 7월부터 10월까지 측정한 데이터를 활용하여 산정한 결과로 써레질, 이앙기간에 발생한 단위면적당 오염부하량은 포함되지 않은 결과이다, 따라서 추가적인 연구를 통해 효과를 검증할 필요가 있을 것으로 판단된다.

Purpose: The purpose of this study was to identify the needs of health education in students, their parents and teachers in the elementary, middle and high schools and the current situation of health education class. Method: The subjects of this study were a total of 9450 persons including students, their parents and teachers from 279 schools throughout the country. They were selected through convenient sampling. Data were analyzed through x^(2)­test and ANOVA. Result: Students, their parents and teachers replied that 18 dimensions of health education class (DHEC) are necessary. The four DHEC - healthier life style, sex education, mental health and safety education - showed high educational needs in students, their parents, and teacher. High school students had higher educational need of 'symptom management for daily living' than elementary and middle school students. Students, their parents and teachers in elementary school had higher educational needs of 17 DHEC that those in middle and high school. The percentages of schools with health education class taught by health teachers were 99.2%, 75.5% and 66.0% respectively in elementary, middle and high schools. Health education was given mainly using physical education classes at elementary schools, and creative class hours at middle and high schools. In general, health education took 1-3 hours per week at elementary schools, and less than an hour at middle and high schools. Conclusion: Therefore, based on the results, systematic health education class should begin from elementary school to meet the need of health education in students, their parents and teachers, and further study should be made on the number of hours required and the amount of contents of 18 DHEC.

Background: The purpose of this study was to document the incidence and clinical characteristics of patients with tuberculosis (TB) in combat and auxiliary police, living in a group, in Korea where the incidence rate of active TB in a general population is higher than in Western countries. Materials and Methods:We retrospectively reviewed the medical records of all tuberculosis patients diagnosed at National Police Hospital from January 2002 through December 2004. Results:In 2002-2004, a total of 156 cases of tuberculosis were identified with the mean (Standard deviation) age of 20.6 (±1.0) years. Of these, 134 (85.9%) patients were registered as new cases, 11 (7.1%) as relapse, 2 (1.3%) as failure, 5 (3.1%) as treatment-after-default cases whereas 4 (2.6 %) patients were not included in any categories. Average annual new TB rate and smear-positive TB rate were 86.5/10^(5) and 17.4/10^(5) person-years, respectively. In 12 of 31 smear-positive cases, time from onset of symptoms to diagnosis was more than 30 days. Two multidrug-resistance TB cases were identified and two suspected outbreak episodes of TB had occurred during 3 years. Conclusion:There was no statistically significant difference in the incidence rate of new cases of TB between the general population aged 20 to 29 years and combat and auxiliary police in Korea. 배경 : 국내 결핵의 발생은 감소 추세에 있으나 여전히 후진국형 발생양상을 보이고 있다. 특히 집단생활을 하는 젊은이들에서 발생하는 결핵의 유행이 간헐적으로 알려지고 있어 우려를 낳고 있다. 이에 저자들은 최근 전경대원의 결핵 발병 양상에 대해 알아보고자 본 연구를 시행하였다. 재료 및 방법 : 2002년 1월부터 2004년 12월까지 3년간 경찰병원에서 결핵 진료를 받은 전경대원의 의무기록을 후향적으로 분석하여 연도별 결핵 신환발생률, 도말양성결핵 신환율, 진단 지연, 집단발병, 다제내성결핵을 조사하였다. 결과 : 연도별 결핵 신환자 수(10만명당 발생추정치)는 2002년 50명(83.6명), 2003년 42명(83.7명), 2004년 42명(93.5명)이었고 도말양성 폐결핵 신환자 수는 2002년 10명(16.7명), 2003년 11명(21.9명), 2004년 6명(13.4명)이었다. 3년간 도말양성 폐결핵 환자는 31명이 있었고 그 중 12명은 호흡기 증상 발생 30일이 지나서 진단을 받았다. 다제내성 결핵은 2명이 있었으며 결핵의 집단발병이 의심되는 사례는 2차례 있었다. 결론 : 전경대원과 20-29세 연령군 일반인의 결핵 신환발생률, 도말양성 폐결핵 발생률의 통계적으로 유의한 차이는 없었다.

Streptomyces albus KSM-35의 amylase의 유전자를 Bacillus subtilis LKS88에서 발현시킨 균주를 사용하여 amylase의 생산에 미치는 몇가지 요인들을 조사하였다. 본 실험에 사용한 탄소원들중에서 sodium citrate와 왕겨의 효소 생산량이 가장 높았고, 이들을 1:1의 비율로 혼합하여 첨가하였을 때 효소의 생산량은 대조군으로 사용한 가용성 전분에 비하여 20배 이상 증가하였다. 질소원으로 대두박을 사용하였을 경우 yeast extract의 첨가량을 줄이면서 효소의 생산량을 증가시켰다. 배양을 위한 초기 pH를 60으로 조절하고 SDS를 0.01%첨가하였을 때 대조구조보다 높은 효소 생산량을 나타내었다. Bacillus subtilis LKS88 (pASA240)을 sodium citrate와 왕겨 각각 1.5%, K_2HPO_4 0.66%, yeast extract 0.3%, 대두박 0.7%, SDS 0.01% 및 초기 pH를 6.0으로 조절한 배지에서 37℃에서 배양시 최대 효소 활성은 배양 후 36시간에서 나타났으며 이때 효소 활성은 56.6 U/ml이었다. The effects of culture conditions on the production of amylase expressed by Bacillus subtilis LKS88 with a cloned gene from Streptomyces albus KSM-35 were investigated The production of amylase was increased significantly by using sodium citrate and rice hull as a carbon source. In addition, the use of a mixture of sodium citrate and rice hull(1:1) resulted in increase of enzyme production by 20-fold when compared to that of soluble starch. The soybean meal as the nitrogen source could be partially replaced with yeast extract without changing the enzyme production yield. The amylase production was also increased by adjusting initial pH to 6.0 or by adding 0.01% SDS. Maximum amylase production was observed in the medium containing 1.5% sodium citrate, 1.5% rice hull, 0.7% soybean meal, 0.3% yeast extract, 0.66% K_2HPO_4, 0.05% MgSO_4·7H_2O, 0.08% CaCl_2·2H_2O, 0.01% SDS with initial pH of 6.0. The maximum yield of amylase reached 56.6 U/ml when B. subtilis LKS88(pASA 240) was cultured at 37℃ for 36 hr.
