정용준,배종홍,권구호,민경석 한국물환경학회 2004 한국물환경학회지 Vol.20 No.6

An upflow BAF(Biological Aerated Filter) equipped with an expanded clay media was applied to reuse weaving wastewater of water jet loom. The performance of lab-scale biofilter was investigated by the adjustment of EBCTs(Empty Bed Contact Time) and the packing ratio of media, which were changed 1.1 to 3.7hr and 38 to 63%, respectively. In most conditions except 1.1hr of EBCT, BOD, CODcr, SS and Turbidity of the effluent were 1∼4㎎/L, 7∼16㎎/L, 1∼5㎎/L and 5∼14NTU, where their removal efficiencies were 76∼95%, 82∼93%, 63∼94% and 59∼81%, respectively. From the observation of SEM(Scanning Electron Microscope) photographs of porous clay media, it was revealed that this media provided good performance of retaining microbes effectively. In addition, 0.44∼0.49㎏VSS/㎏BOD_(rem). of low sludge reduction was expected. The most efficient back washing cycle and procedure were once per 4 to 9 days and air including collapse-pulsing method, respectively. Therefore, this system can be of use as an weaving wastewater treatment for reuse

최준호,김판구 조선대학교 전자정보통신연구소 2001 電子情報通信硏究所論文誌 Vol.4 No.1

Many kinds of viruses have been occurring in the computer systems. These are able to destroy some critical data and even make the computer system halt their function. Consequently, its damage was enormous. So we need a more efficient method that detects the computer viruses, different from the existing one. As first storage-second detecting method which is inspected by supervisor after storing in the file system can't confront actively the virus intrusion, we propose viruswall system which is able to play a role in warning and data blocking in this paper. In addition, we propose the method that integrates into viruswall system for virus detection and blocking in order to introduce firewall system for this system design.

Semantic interpretation of image IS incomplete without some mechanism for understanding semantic content that is not directly visible For this reason, human assisted content-annotation through natural language is an attachment of textual description (ie a keyword, or a simple sentence) to image However, keyword-based retrieval is in the level of syntactic pattern matching In other words, dissimilarity computation among terms is usually done by using string matching not concept matching In this paper, we present a solution for qualitative measurement of concept-based retrieval of annotated image We propose a method for computerized conceptual similarity distance calculation in WordNet space. Also we have introduced method that applied similarity measurement on concept-based image retrieval When tested on a image set of Microsofts Design Gallery Live, proposed method outperforms other approach.

해수유동모델 결과를 3차원적으로 가시화하기 위한 그래픽 유저 인터페이스를 구축하는 과정에서 지리정보시스템(GIS) 기술을 활용하였다. 연안역 관리에서 GIS 기법은 산재되어 있는 방대한 자료들을 저장하고 이를 3차원으로 가시화하는 기능을 제공하며 해석적, 통계적, 모델링 도구로써 주어진 상황에 적합한 데이터 변환이 가능하도록 해준다. 해수유동모델은 개방경계에서 조석, 바람, 수온, 염분, 강물 유입 및 태양복사 등과 같은 모델입력값을 부여함으로써 구동되며 대상해역은 진해만으로 하였다. 녈 연구에서는 국산 GIS 소프트웨어인 GeoMania (v2.5)를 사용하여 진해만을 대상으로 시뮬레이션된 해수유동모델 결과의 3차원 가시화 모듈을 구축하였다. This study presents an application of GIS technologies to construct the graphic user interface for 3-dimensional exhibition of the results obtained by ocean hydrodynamic model. In coastal management studies, GIS provide a receptacle for scattered data from diverse sources and an improvement of the 3D visualization of such data. Within the frame of a GIS a variety of analytical, statistical and modeling tools can be applied to transform data and make them suitable for a given application. A 3D hydrodynamic model was driven by time-dependent external forcing such as tide, wind velocity, temperature, salinity, river discharge, and solar radiation under the open boundary condition. The Jinhae bay was selected as a case study. Here, we have used GeoMania v2. 5 GIS software and its 3D Analyst extension module to visualize hydrodynamic model result that were simulated around the Jinhae bay.

주길재,박희동,최준호,이인구,이오석,권달호 慶北大學校農業科學技術硏究所 1998 慶北大農學誌 Vol.16 No.-

농산폐자원으로부터 기능성물질인 xylooligo당을 생산하기 위해서 내열성 균주인 S.thermocyaneoviolaceus가 생산하는 xylanase의 생산최적조건을 검토한 결과 0.8% 밀기울, 0.06% yeast extract, 0.06% bactopeptone, 0.05% MgSO₄·7H₂O, 0.005% FeSO₄·7H₂O, 0.05% KH₂PO₄및 0.2% K₂HPO₄를 함유한 배지(pH7.0)에서 50℃, 24시간 배양시 최고효소활성(2.47 unit/ml)의 배양상징액을 얻을 수 있었다. 효소의 최적반응조건은 pH5.5, 65℃였다. 또한 pH안정성을 조사한 결과 pH4.5∼9.5사이에서 4℃에서 12시간후에도 80% 이상의 효소활성을 유지하였고, 열 안정성은 60℃에서 1시간 처리후 94%이상의 효소활성을 유지하는 내열성이 있는 효소였다. 생산된 xylanase birchwood xylan 반응생성물을 TLC 및 HPLC로 확인해 본 결과, pH가 낮을수록(pH 5.0∼6.0) xylobiose와 xylotriose및 소량의 xylose의 양이 증가하였고, pH가 높을수록 (pH8.0∼9.0) X₄이상의 각종 xylooligo당의 양이 상대적으로 증가하였다. 또한 24 시간후에는 xylan의 상대량이 25% 이하로 감소하면서 주분해산물로 xylobiose가 생산되었으며 xylotriose와 xylose 및 X₄이상의 각종 xylooligo당이 생산되었다. A thermotolerant bacterium, Streptomyces thermocyaneoviolaceus which produced xylan-degrading enzymes, utilized excellently xylan of wheat bran by producing the enzymes in comparison with that of birchwood or oat spelts. Optimal enzyme production was achieved in WB medium containing 0.8% wheat bran, 0.06% yeast extract, 0.06% bactopeptone, 0.05% MgSO₄·7H₂O, 0.05% FeSO₄·7H₂O, 0.05% KH₂PO₄ and, 0.2% K₂HPO₄(pH 7.0) at 50℃ for 24 hrs. The optimal pH and temperature for the hydrolysis of xylan were pH 5.5 and 65℃, respectively. The enzyme activity was retained more than 80% at the range from pH 4.5 to pH 9.5 at 4℃ for 12 hrs and 94% on the heat-treatment at 65℃ for 1 hr. Xylobiose, xylotriose, xylose, and other xylooligosaccharides were produced as end products from hydrolysis of birchwood xylan by the xylanase of S. thermocyaneoviolceus.

박성은,최우정,이원찬,구준호,정래홍,박종수 한국지리정보학회 2004 한국지리정보학회지 Vol.7 No.3

연안 양식어장의 정보 관리에 실용적인 지리정보시스템(GIS)을 적용함으로써 어업종사자와 연안 관리자에게 실현 가능한 관리방안을 제시하고 수산업 발전을 위한 유연한 의사결정의 기반을 마련하고자 하였다. 연안 양식어장의 효과적 관리는 경제적 실행 가능성과 운영비용에 영향을 미치며 양식 대상생물의 생산 및 사망률과도 관계가 있으므로 매우 중요하다. GIS는 양식어장 정보의 효율적인 관리도구로서 개인 및 공공분야에서 폭넓게 사용되고 있으며 해양수산 관련분야에서도 활발히 적용되고 있다 본 연구에서는 진해만을 대상으로 연안 양식장 자료의 3차원 가시화 모듈을 구축하였다. This paper illustrates some practical geographic information system (GIS) applications for aiding fishery managers and coastal area planners in analysing the likely control scheme of coastal farming areas, and in providing a flexible framework for decision making on fishery development and zoning issues. The effective management of marine farming operation is vitally important since it can greatly influence economic availability by determining capital outlay and by affecting running costs, rates of productions and mortality factors. GIS has been widely adopted elsewhere as a potent management tool in both the private and public sectors. GIS is now being extensively adopted in marine-associated activities. Here, we have used GeoMania v2. 5 GIS software and its 3D Analyst extension module to visualize marine farming areas data that were collected around the Jinhae bay.

오은숙,강무일,이원영,오기원,임동준,이소영,이정민,고승현,김성래,안유배,손현식,윤건호,차봉연,이광우,손호영,강성구 대한당뇨병학회 2000 임상당뇨병 Vol.1 No.1

연구배경: 감염질환은 혈관질환과 함께 당뇨병의 중요한 사망원인의 하나이며, 혈당조절이 불량할수록 감염 빈도가 증가됨은 잘 알려져 있다. 간농양의 발생이 있어서도 당뇨병은 중요한 기저질환 중의 하나이다. 일반적으로 간농양의 가장 흔한 원인균은 Escherichi coli라고 알려져 있으나, 최근 당뇨병을 가진 간농양 환자에서 Klesiella pneumoniae의 검출이 증가되고 있다. 또 최근 연구에 의하면 K.pneumonie가 간농양의 가장 흔한 원인균이며, K. pneumoniae에 의한 간농양은 K.pneumoniae 이외의 균주에 의한 간농양보다 당뇨병과 밀접히 관련되어 있다고 보고된 바 있다. 이에 저자들은 간농양 환자를 대상으로 당뇨병환자의 빈도를 알아보고, 그 원인균 및 특징을 비당뇨병 환자들의 경우와 비교해 보고자 하였다. 방법: 1992년 1월부터 1999년 6월까지 방사선학적 검사 혹은 수술에 의해 간농양이 확인되거나, 경피적 천자나 수술을 통한 배농액 배양, 혹은 혈액 검사에서 원인균이 증명된 182명의 환자를 대상으로 후향적 임상고찰을 실시하였다. 결과: 화농성 농양을 가진 167명의 환자(남:94명, 여:73명)중 당뇨병을 가진 환자는 54명 (남:30명, 여:24명)으로 32.3%를 차지하였다. 환자의 평균나이는 당뇨군에서 62.1 ± 13.4세, 비당뇨군에서는 55.1 ±15.5세로 당뇨군에서 높았으며(p=0.0021), 남녀간의 평균나이 비교 시 두 군 모두 여성의 나이가 의미있게 높았다. 비당뇨군에 비하여 당뇨군의 경우 저알부민혈증의 빈도와 aspartate transaminase가 증가되어있었다. 원인균주는 K. pneumoniae (당뇨군54%, 비당뇨군 39.1%), E. coli(당뇨군 17.5%, 비당뇨군 18.8%), Pseudomonas aeruginosa, Streptococcus viridans, Enterococcus 순이었으며 두 군간의 의미는 차이는 없었으나 K. pneumoniae의 경우 다른 균종에 비해 단독감염의 빈도가 높았다(82.8%). 사망률은 당뇨군에서 16.7%, 비당뇨군에서 7.1%로 당뇨군에서 의미있게 높았으며(p=0.019), 당뇨군에서의 사망환자는 모두 패혈증이 동반되어 있었다. 당뇨환자의 사망군은 생존군에 비해 당뇨병 이환기간이 길고 혼합감염의 빈도가 높았다(p=0.046). 검사실 소견에서는 총 빌리루빈 및 알카리성 포스파타제의 증가가 관찰되어 있었다. 결론: E. coli가 간농양의 주된 원인균이라는 기존 보고와는 달리 당뇨군과 비당뇨군 모두 K. pneumoniae가 간농양의 주된 원인균이었다. 또한 당뇨 유병기간이 길고 당뇨조절이 불량한 환자에서 혼합감염이며 총 빌리루빈 및 알카리성 포스파타제의 증가등과 같은 위험인자가 존재할 경우 사망률이 증가될 수 있으므로 이들 군에서는 적극적인 치료가 필요할 것으로 사료된다. Background: Liver abscesses are commonly associated with underlying disease, particularly diabete mellitus. The number of the liver abscesses caused by Klebslella pneumoniae in diabetic patient has been increased in Korea nowadays. This study was conducted to clarify the clinical presentation and prognostic factors of pyogenic liver abscesses, especially in diabetic patients and to determine the proportion of K. pneunomiae as a pathogen in liver abscess in Korea. Methods: Medical records of 167 patients treated for pyogenic liver abscess from January, 1992 through June, 1999 were reviewed retrospectively in detail. Major Pathogenic organism, clinical manifestations, prognostic factors, the importance of diabetes mellilus as an underlying disease and its effect on clinical features and prognosis were analyzed. Results: Among 167 cases of pyogenic liver abscess, underlying diabetes mellitus was present in 32.3%. The mean age of patients was 62.7 13.4 years in diabetic liver abscess group and 55.1 15.5 years in non-diabetic liver abscess group. Most liver abscesses were cryptogenic in origin or secondary to the billary tree diseases. The clinical presentations among the two groups were not significantly different. When compared to patients without diabetes, patients with diabetes had significantly higher proportions of hypoalbuminemia and elevated aspartate transaminase level. The most common organism of the pyogenic abscess was K. pneumoniae in both groups. Percutaneous drainage of the abscess with appropriate antibiotics was the most commonly used therapeutic modality in liver abscess. The mortality rate of diabetic liver abscess is 16.1 % and 7.1% in nondiabetic liver abscess. Complications, especially septicemla, were found more frequently in patients with diabetes than in patients without diabetes (64.8% vs 28.3%, septicemia : 31.5% vs 9.7%). The factors influencing mortality in the diabetic liver abscess were disease duration, mixed infection, presence of septicemia, elevated bilirubin and alkaline phosphatase. Conclusions: In contrast to prior report that the E. coli was the most common pathogen in liver abscess, we found that K. pneumoniae was the most common organism cultured in liver abscess. Diabetic patients have more complications and higher mortality than patients without diabetes. Early detection and proper treatment are needed to improve the outcome for diabetic patient with liver abscess.

The purpose of this study is to observe the effect of elasticity of taping on ankle muscles’activity and endurance after plyometric training that easily causes ankle injury, and provide baseline data for physical therapy intervention methods. The study subjects are 24 male students in their 20s who attend N University in Choongnam. They were divided into three groups; 8 subjects in the elastic taping group, 8 in the non-elastic taping group, and 8 in the non-taping group(control group). They had plyometric training for 6 weeks. After the training, this study measured their maximum voluntary isometric contraction(MVIC) and muscle endurance of the muscles around ankle joint. The experiment result is as follows. After the training, all three groups showed improvement in muscle strength and endurance. The elastic taping group showed insignificant improvement in muscle strength but significant increase in muscle endurance in plantarflexion. In dorsiflexion, both muscle strength and endurance increased significantly. The non-elastic taping group showed insignificant improvement in muscle strength but significant increase in muscle endurance in plantarflexion. Taping during plyometric training had a little or insignificant effect on muscle endurance and strength compared to the non-taping group.
