자연환경과 인위적 환경변화에 의한 홍수재해는 하상변동과 밀접한 관계를 갖는다. 본 연구는 금강유역을 대상으로 지리정보시스템(GIS)과 원격탐사(RS)를 이용하여 유역에서의 토양침식과 하상변동의 관계를 규명하고자 하였다. 지리정보시스템에서 범용토양유실공식 (USLE)을 이용하여 토양침식율을 계산하였다. 공주에서 이포까지 하상지형을 측량하였고, 3차원의 하상변화도를 작성하였다. 1982년에서 2000년까지 Landsat TM 영상을 이용하여 금강유역의 하상변동을 추적하였다. 연구결과, 강경일대의 토양침식율은 $1.8\;kg/m^2/$년이며, 하상증가율은 $+5\;cm/m^2/$년으로 산정되었다. 따라서 금강하류의 하상변화는 일정한 비율로 토양침식에 의하여 영향을 받는 것으로 해석된다. 또한 하상변동은 주로 금강의 지류와 본류의 접합부 하류일대에서 발생하였다. 금강하류에서 하상변동은 하성 세골재 채취가 하나의 원인으로 해석될 수 있으며, 골재채취로 인하여 1991년도에서 1995년도 사이 금강하상 위에 노출된 하상면적의 감소를 초래했던 것으로 추정된다. 한편, 금강유역 하상을 따라 교량건설, 경작지 조성을 위한 사주개간, 제방과 같은 수중 구조물들 설치는 퇴적물 집적과 퇴적하상의 노출면적 증가를 초래하였던 것으로 추정된다. Flooding hazard caused by natural and artificial environmental changes is closely associated with change in river bed configuration. This study is aimed at explaining a river-bed change related to soil erosion in the Keum river basin using GIS and RS. The USLE was used to compute soil erosion rate on the basis of GIS. River-bed profiles stretching from Kongju to Ippo were measured to construct a 3D-geomorphological map. The river-bed change was also detected by remote sensing images using Landsat TM during the period of 1982 to 2000 for the Keum river. The result shows that USLE indicates a mean soil erosion rate of $1.8\;kg/m^2/year$, and a net increase of a river-bed change at a rate of $+5\;cm/m^2$/year in the Kangkyeong area. The change in river-bed is interpreted to have been caused by soil erosion in the downstream of the Keum river basin. In addition river-bed change mainly occurred on the downstream of the confluence where tributaries and the main channel meet. Other possible river-bed change is caused by a removal of fluvial sand aggregates, which might have resulted in a net decrease of exposed area of sediment distribution between 1991 and 1995, while a construction of underwater structures, including a bridge, a reclamation of sand bars for rice fields and dikes, resulted in an increase of the exposed area of river-bed due to sediment accumulation.

We investigated the physicochemical properties of brown rice by cultivar to select cultivar suitable for making brown rice porridge. The moisture content of the brown rice ranged from 8.79~11.78% with the highest varieties being 'Geonyangmi'. The crude ash and crude lipid content ranged from 1.02~1.65% and 1.65~3.26%, while the rest were similar except for 'Daebo'. Crude protein also had the lowest 'Daebo' and generally glutinous rice showed higher crude protein content than common rice. The hardness showed that 'Seolgaeng' and 'Keunnun' were the lowest, and 'Haiami' was the highest. In the RVA analysis, the setback was in the range -80.61~22.44 and was low in the order of 'Wolbaek', 'Baekjinju'', and 'Dongjinchal'. As a result of water binding capacity (WBC) measurement, 'Sindongjin', 'Geonyang' and 'Samkwang', were high in common rice, and 'Dongjinchal' and 'Hwaseonchal' were high in glutinous rice. Generally, solubility and swelling power in common rice was found to be lower than in glutinous rice. As a result, 'Samkwang' is considered suitable for brown rice porridge production because of high WBC, breakdown, and low setback.

Purpose: To report a case of rapidly progressing foveal atrophy with tuberculous serpiginous-like choroiditis. Case summary: A 54-year-old female patient had decreased vision of hand motions (os) for 3 days. Fundus examination showed optic disc swelling and yellowish chorioretinal lesions in the posterior pole (os). Optical coherence tomography (OCT) showed intraretinal edema and subretinal fluid in the left macula. Routine laboratory tests, serologic tests, and magnetic resonance imaging results were normal except for erythrocyte sedimentation rate (28 mm/hr). Fluorescein angiography showed the chorioretinal lesions appeared to be early hypofluorescence followed by late hyperfluorescence. Indocyanine green angiography showed hypofluorescence during early and late phases and the result of interferon-gamma release assay was positive. Under diagnosis of tuberculous serpiginous-like choroiditis, anti-tuberculous therapy combined with systemic corticosteroid was started. Despite decreased optic disc swelling, OCT showed a rapid progression of foveal atrophy within 2 weeks. Twelve weeks later, visual acuity was finger count at 10 cm. Six months later, best-corrected visual acuity and foveal atrophy were no interval change. Conclusions: Tuberculous serpiginous-like choroiditis with foveal involvement can show rapidly progressive foveal atrophy and poor visual prognosis.

Antimicrobial activity and bactericidal activity of Caesalpinia sappan L. extracts were investigated against five food-borne pathogens, E. coli, S. aureus, S. typhimurium, B. cereus and L. monocytogenes. Methanol extract of Caesalpinia sappan L. revealed antimicrobial activities against five pathogens. In particular, by paper disc diffusion the highest activity was shown against L. monocytogenes. Antimicrobial activities of methanol extracts showed the most potent activities, but hexane fraction had no activity. Fractions of ethyl acetate and butanol turned out to have higher antimicrobial activities against Gram(+) bacteria than Gram(-) bacteria. The minimum inhibitory concentration against five food-borne pathogens was 1.563 mg/ml on Gram(+) bacteria and 3.125 mg/ml on Gram(-) bacteria. The result of antimicrobial activity in a shaking flask method showed that bacterial growth rate fell by more than 99.999% at 3.125 mg/ml of methanol extract. The highest rate of viable reduction (99.998%) was shown at 0.781 mg/ml of methanol extract against L. monocytogenes. After five minutes of reaction between test strains and methanol extracts, the growth rates of five kinds of bacteria were reduced by more than 99.999% at a concentration of 100 mg/ml. Therefore, it is suggested that methanol extracts of Caesalpinia sappan L. can be developed as a natural sanitizer or disinfectant.

This article aims at finding the ways, on the basis of the studies about the behaviors to search the existing CD-ROM databases, so that the searchers who retrieve the on-line MEDLINE used in the medical libraries can use the data more efficiently than now. We gave the questionnaires to the librarians in 60 medical libraries and searched the literatures and realities on the behaviors of the data uses to examine the search behaviors of the MEDLINE in the medical libraries. The result is as follows: 1) The medical data system rate for single users was $53\%$ and the ons for multi users $43\%$. As for the time which users retrieve for a week, under two hours was $75\%$, between 3 and 8 hours $18.3\%$, and eve. 9 hours $6.7\%$. 2) The increasing factors of the search result are (1) an enough discussion and interview between librarians and users, and (2) the use of the correct indexing terms, Thesaurus, and Keyword. In principle users must search directly. However, the librarians searched instead in case that the retrieval result was under two hours a week$(75\%)$. 3) As for the search fee, $91\%$ was free and $9\%$ was charged. Also search effectiveness was enhanced by the means of Inter-Library Loan Service & Information Network. 4) The medical librarians answered the questionnaire that they need the application education of professional knowledge, medical terms(thesaurus) and electronic medium, and also they need the computer education, interview technique and reeducation to give a satisfactory service. 5) As for the satisfactory degree of MEDLINE application, they answered $44.6\%$ for economy, $38.2\%$ for the conveniency of the time required, and $58.9\%$ for the users' search satisfaction answered respectively. 6) The application of MEDLINE system enhanced the medical libraries' image and had an effect on the users' satisfaction of using the data and search, the data activities and the research achievement. 7) In the past MeSH was used but as the time passes CD-ROM MEDLINE search behavior was preferred to On-line one. 본 연구는 기존의 CD-ROM 데이터베이스 탐색형태에 관한 연구를 기초로 의학도서관에서 사용하고 있는 온라인 MEDLINE을 검색하는데 있어 연구자들이 정보이용을 보다 효율적으로 제공할 수 있는 방안을 모색하는데 그 목적이 있다. 의학도서관에서의 MEDLINE 탐색형태를 조사하기 위하여 정보이용 행태에 관한 문헌조사와 실태조사를 설문지 조사방법으로 60개 의학도서관을 대상으로 의학전문사서의 정보이용 행태를 추출하였다.
