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.

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.

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.

이진영,김강민,강재선,Lee, Jin Young,Kim, Kang Min,Kang, Jae Seon 한국해양바이오학회 2007 한국해양바이오학회지 Vol.2 No.1

바실러스 폴리퍼멘티쿠스 에스씨디는 활성아포를 형성하여 장까지 도달하는 특성 때문에 장기적인 장 질환 치료에 사용되어져 왔다. 뿐만 아니라 강력한 항생물질을 생산하는 장점을 가지고 있다. 현 연구는 바실러스 폴리퍼멘티쿠스 에스씨디와 콩을 함께 발효시킨 것 (BPFS)과 그것의 생균제 특성에 관하여 조사하였다. 바실러스 폴리퍼멘티쿠스 에스씨디는 와 BPFS는 병원성 그람양성 (스트렙토코커스 파라우베리스, 스트렙토코커스 이니에, 락도코커스 가르비에), 그람 음성 (플렉시박터 트렉튜오서스, 비브리오 하베이, 비브리오 불니피쿠스, 비브리오 오다리), 곰팡이 (아스파라질러스 니거, 아스파라질러스 오리자에)에 이르기까지 넓은 범위의 항균성을 가졌다. BPFS에 의한 생존율 증가와 부영양화로 인한 수질오염의 정화작용을 관찰하기 위해서 통영 앞바다 양식장에서 조피볼락을 사용해서 현장 실험을 하였다. 그 결과, 해양 병원성 유해 박테리아에 노출시키고 일반 사료만 복용시킨 군에서는 99%의 폐사율을 보였으나, BPFS를 사료와 함께 복용시킨 군에서는 먹이 유인효과에 의한 성장률의 증가와 부영양화에 의한 수질오염을 정화하는 작용이 관찰되었다. 따라서 BPFS는 양식업에서 항생물질 대체제, 사료첨가제, 부영양화에 의한 정화제로서 개발하여 산업화하기 용이한 후보물질이라고 사료된다. Bacillus polyfermenticus SCD (B. polyfermenticus SCD) has been appropriately used for the therapy of long-term intestinal disorders, because live strains in the form of active endospores can successfully reach the target intestine in humans. B. polyfermenticus SCD produces the most antibiotic-related materials. In the present study, B. polyfermenticus SCD was fermented with soybeans (BPFS) and its probiotic properties were investigated. B. polyfermenticus SCD and BPFS showed a broad spectrum of antimicrobial activity against pathogenic Gram-positive (Streptococcus parauberis, Streptococcus iniae, Lactococcus garviae) and Gram-negative (Flexibacter tractuosus, Vibrio harveyi, Vibrio vulnificus, Vibrio ordalii) bacteria and moulds (Aspergillus niger, Aspergillus oryzae). Sebastes schlegeli were used to examine survival rate and cleanup action by BPFS. Bacterial infection resulted in a mortality of up to 99% in the commercial fodder fed groups. BPFS both enhanced the growth rate of fry by improving their appetite and had cleaned by decreased eutrophication. Therefore, it seems appropriate that BPFS should be developed as an antibiotic replacement, favorable fodder additive, and antifungal material in fish farming systems.

스마트그리드 환경하의 가정용 AMI 자료를 위한 시계열 군집분석 연구

이진영,김삼용,Lee, Jin-Young,Kim, Sahm 한국통계학회 2020 응용통계연구 Vol.33 No.6

스마트그리드 환경하에서 ICT 기술의 발달로 AMI 기기를 통해 가정의 실시간 전력사용량을 수집할 수 있게 됨에 따라 이러한 자료들을 활용하여 보다 더 정확한 가정용 전력사용량 예측을 할 수 있게 되었다. 본 논문에서는 1시간 단위 가정용 전력사용량 자료를 바탕으로 ARIMA, TBATS, NNAR 모형을 사용하여 전력수요를 예측하는 모형을 연구하였는데, 기존과 달리 가구 전체 사용량을 한 번에 예측하는 것이 아닌 유사한 전력사용패턴을 나타내는 가구들을 군집하여 군집별로 예측 모형을 수립하고 각 모형별 예측치를 합산하여 예상 전력사용량을 산출하였다. 특히 전력사용량 자료는 전형적인 시계얼 자료로서 군집분석 방법으로 시계열에 적절한 방법을 선택하였으며 본 논문에서는 동적타임워핑(dynamic time warping)과 Periodogram 기반의 방법을 사용하였다. 연구 결과 사용량이 유사한 가구들을 군집하여 전력사용량을 예측하는 것이 한 번에 예측하는 것보다 예측 성능이 더 우수한 것으로 나타났으며 예측 모형 중에서는 여름철의 경우 NNAR 모형이, 겨울철의 경우 TBATS 모형의 성능이 가장 좋았으며 군집분석 방법은 군집 간 패턴의 차이가 명확히 나타난 동적타임워핑 방법을 사용했을 때 예측 성능의 향상이 가장 많았다. Residential electricity consumption can be predicted more accurately by utilizing the realtime household electricity consumption reference that can be collected by the AMI as the ICT developed under the smart grid circumstance. This paper studied the model that predicts residential power load using the ARIMA, TBATS, NNAR model based on the data of hour unit amount of household electricity consumption, and unlike forecasting the consumption of the whole households at once, it computed the anticipated amount of the electricity consumption by aggregating the predictive value of each established model of cluster that was collected by the households which show the similiar load profile. Especially, as the typical time series data, the electricity consumption data chose the clustering analysis method that is appropriate to the time series data. Therefore, Dynamic Time Warping and Periodogram based method is used in this paper. By the result, forecasting the residential elecrtricity consumption by clustering the similiar household showed better performance than forecasting at once and in summertime, NNAR model performed best, and in wintertime, it was TBATS model. Lastly, clustering method showed most improvements in forecasting capability when the DTW method that was manifested the difference between the patterns of each cluster was used.
