In recent years, gonorrhea has been pandemic and remains one of the most common STDs in the world, especially in developing countries. For the detection of a more effective therapeutic regimen and assessing the prevalence of Penicillinase Producing Neisseria gonorrhoeae(PPNG), we have been trying to study the patients who have visited the Venereal Disease Clinic of Choong-Ku Public Health Center in Seoul since 1980 by menas of the chromogenic cephalosporin method. In 1998, 93 strians of N. genorrhoeae were isolated, among which 60(64.5%) were PPNG. The prevalence of PPNG in Seoul, which had been decreased to 39% in 1996 after a peak of 74.3% in 1993, is increased to 64.5% in 1998.

황재호,임우재,안석환 釜山水産大學校 1994 釜山水産大學 硏究報告 Vol.34 No.1

In this paper, stress corrosion cracking behavior, and stress corrosion cracking behavior under cavitation-erosion of water injection were investigated. Main result obtained were as follows 1) The weight loss of stress corrosion under stress is less susceptive than that of stress corrosion under stress and cavitation environment. 2) Cracking growth rate of stress corrosion under stress and cavitation is faster than that of stress corrosion under stress. 3) Corrosion potential of stress corrosion under stress and cavitation is less noble than that of stress corrosion under stress. And corrosion current density under stress and cavitation is higher than that of stress corrosion under stress.

치환된 perovskite형 복합 산화물 LaCo_1-xCu_xO_3(x=0, 0.1, 0.3, 0.5)의 환원 반응성에 대한 연구

황호순,이규석,박일현 성균관대학교 기초과학연구소 1993 論文集 Vol.44 No.1

B site substituted mixed oxides LaCo_(1-x)Cu_xO_3(X=0, 0.1, 0.3, 0.5) were prepared by citrate sol-gel method in air, 850℃. By the thermal gravimetric analysis(TGA) and XRD analysis all of these oxides were single phase perovskite of rhombohedral structures. A as the amount of substituent increases, the amount of oxygen decreases and the lattice volume increases. Oxygen stoichiometry and lattice parameters of these oxides are as follows. LoCoO_3.0(a=5.44, c=13.10 Å), LaCo_0.9Cu_0.1O_3.0(a=5.44, c=13.2 Å), LaCo_0.7Cu_0.3O_2.92(a=5.46, c=13.14 Å), LaCo_0.5Cu_0.5O-2.84(a=5.45, c=13.27Å) According to the TPR results, LaCoO_3 and LaCo_0.5Cu_0.5O_2.84 undergo two-stage reduction stages, but LaCo_0.9Cu_0.1O_3.0 and LcCo_0.7Cu_0.3O_2.92 undergo three stages. The first reduction reaction of these oxides is one electron reduction reaction(oxygen 0.5mole). Reoxidated oxide in air at 1000℃, LaCoO_2.94 shows oxygen defect but the TPR result is similar to that of as-prepared oxide. By the reaction kinetics, the activation energy of LaCo_09.Cu_0.1O_3 is found to be the lowest value among those of the substituted oxides LaCo_(1-x)Cu_xO_(3-y).

The object oriented visualization of situations is an essential component part in many applications. We simulated spatial moving objects of situation using multi-media environment. An object is composed of multimedia datas that can express graphic and sound. By composing these objects we can have group cbject. Also, we can execute event by defining stuations that are occured according to be animating object.

채윤석,강호종,황서진 진주산업대학교 농업기술연구소 2007 農業技術硏究所報 Vol.20 No.-

고온기 고추육묘에 처리한 생장억제제 처리 효과 및 정식 후 생육억제를 회복하기 위하여 GA, 관수, 고온처리 효과에 대한 연구 결과는 다음과 같다. 1.생장억제제 트리아졸계 처리 횟수에 따라 초장 및 주경장은 뚜렷한 차이를 나타냈고 근장도 2회 처리를 함으로 1회 처리를 한 것보다 발달하지 않았다. 2. 왜화된 고추묘의 생육억제 해소에 미치는 영향은 초장 및 주경장의 생장에는 GA처리구가 뚜렷하였으나 다른 처리구는 비슷한 경향이었고 경경은 변화가 없었다. 3. 생육회복을 위한 처리별 생체 및 건물중은 정식 후 30일까지는 변화가 거의 없었으나 그 후 45일까지 급격히 증가하였는데 고온 및 관수처리구에서 뚜렷한 차이를 보였으며 45일 이후에는 모든 처리구에서 비슷한 경향을 보였다. 4. 정식 45일 경 처리구간 엽록소 함량은 GA처리구에서 가장 낮았으며 다른 처리구간에는 비슷했다. This study was carried out to find effects of restoration of hot pepper seedling dwarfed by the treatment of diniconazole by introducing GA₃, Irrigation and high temperature at knight and the results obtained are summarized as follows. The main results of this research are summarized as follows. 1. In the case of plant height and main stem hight treated with the first time and second time diniconazole showed the strongest effect than untreatment. The root length treated with diniconazole the first time effect gradually disappeared than the second time. 2. Sprays of GA₃100ppm to the dwarfed seedlings by diniconazole pretreatment were effective in counteracting the plant height and main stem height growth inhibition caused by diniconazole pretreatment. 3. The fresh and dry weight of pepper seedling were not significantly different untill 30days in planting, but were increased to 45days from 30days in planting. 4. The chlorophyll content were decreased more or less treatment of GA₃ 100ppm after 45days in planting.

최석근,김명호,황창섭 한국지리정보학회 2003 한국지리정보학회지 Vol.6 No.3

본 연구는 대축척 수치지도 ver. 2.0(1/5,000)을 이용하여 소축척 수치지도 ver. 2.0(1/25,000)으로 제작하기 위한 처리공정을 개발하였다. 기존 수치지도와 달리 수치지도 ver. 2.0은 속성정보 및 면처리 등 많은 정보들을 포함하고 있기 때문에 이를 효율적으로 처리하기 위하여 소축척 수치지도의 지형·지물코드에 포함되지 않는 레이어를 삭제하고, 자료처리를 8대 지형·지물별로 분류하여 처리한 후, 자료를 병합하는 과정으로 작업공정을 도출하였다. 따라서 본 연구에서 개발한 작업공정은 향후 최적 자동일반화시스템 개발시 기초자료로 이용할 수 있을 것이고, 소축척 수치지도 및 각종 주제도 제작에 기여할 수 있을 것이다. This paper proposes a work procedure for generalizing large-scale digital maps ver. 2.0(1/5,000) into a small-scale digital map)1/25,000). Unlike a existent digital map, the digital map ver. 2.0 has a variety of attribute data as well as graphic data. To perform an efficient map generalization with these structural properties, we establish a work procedure as follow; firstly, delete layers which don's exist in small-scale digital map's feature code, and secondly, generalize features which have been classified into 8 layers, and finally merge 8 layers which have been generalized into 1 layer. Therefore, we expect that a work procedure which is proposed in this paper will play a fundamental role in automated generalization system and will contribute to small-scale digital mapping and thematic mapping.

웹기반의 가축전염병 발생자료 관리시스템(AIMS) 개발

박병호,김석재,황인진,김시동,남향미,위성환 한국농업정보과학회 2003 농업정보과학 Vol.4 No.1

The AIMS(Anima1 Infectious Disease Data Management System) was developed to collect and analyze data on animal infectious disease outbreak (62 diseases). When an animal infectious disease is confirmed at a diagnostic laboratory, the disease outbreak is then reported to the regional government through AIMS. After the regional government confirms the number of animals infected or dead, outbreak date and etc, this information is reported to the Ministry of Agriculture & Forestry and the National Veterinary Research & Quarantine Service through AIMS. The AIMS analyzes the outbreak data and reports the outbreak statistics by region, month and year to them. In addition, the AIMS can identify the farm where there was an outbreak of the animal infectious disease. There are four user roles : 1) Administrator, responsible for the overall operation of the system. 2) Inspector, responsible for confirmation of the animal infectious disease outbreak. 3) Pathologist, responsible for input to an animal infectious disease at first. 4) Gallery, only able to read the outbreak statistics. The AIMS has been implemented using the ASP technology and is operated on the web to allow easy access. The data, middle and presentation tier are based on MS-SQL 2000 server, Microsoft transaction server and Internet Explorer, respectively. The database's stored procedure was used to improve the performance. In addition to above software, the dextupload software is used to upload the files. By using the AIMS, a more accurate statistics for the animal infectious disease outbreak is expected.

We propose SKKU Multimedia Distance Education System for distance education between nature science campus(Suwon) and social science campus(Seoul) in Sung Kyun Kwan University on DooRae (Distributed Object Oriented Multimedia Application Crafting Environment for Collaboration) framework (or platform). We support ONE : N study mode for a group lecture and discussion between two campus, and also we support mediation for floor mode of a group lecture and brain storming for floor mode of discussion. The communication portocol of this system is composed of TCP/IP and UDP, and the network type is composed of WAN(El line)for between the Suwon campus and Seoul campus, ATM LAN for each campus(local site). And, this system supports the application development of the collaborative multimedia environment connected with the various network in the CBM (Computer based Multimedia) based. Also, it does not restrict on space between a teacher(s) and a student(s) into cyberspace which made by network. This system has an interaction, late comer, a question and an answer, multi-session, application sharing and whiteboard which resembles chalkboard. Also, various supplementary functions such as video conference and voice conference for this system are what makes face-to-face education effective. Also it supports real or non-real type. The operation system developed on windows 95.
