본 연구의 목적은 트위터에서 수집된 트윗들의 감성을 분석하고 각 문장의 감성 정보를 반자동으로 부착하여 감성 말뭉치를 구축할 수 있는 시스템의 구현이다. 트위터 API를 이용해 트윗을 수집한 후 각 트윗이 어떤 감성을 갖는지 감성사전을 이용해 분석한다. 사용자는 감성 분석 결과를 확인하고 누락된 감성 정보를 추가하거나 의존구조 사이에 존재하는 감성 정보를 추가할 수 있다. 감성 정보는 JSON 구조로 부착함으로써 감성 말뭉치 구축 및 활용에 용이하게 하였다. 제안 시스템은 긍정, 부정, 중립 문장에 대한 감성 분석 결과 약 76%의 성능을 보였다.

Epidemic malaria is prevalent in the demilitarized zone and the northern area of Kyonggi province in Korea. Malaria has broken out in Gangwha-Gun since 1997 due to geographical condition. The results obtained from an epidemiological surveillance for the malaria that happened in 1999 were as follows ; Anopheles sinensis collected in UV-light traps in the barn in Wolgogri and Dangsanri of Songhaemyon showed the distribution of 27,156 of 49,280 figures, corresponding to 55.1%, between July and August. The numbers of patients with malaria were 48(32.4%) in July, 36(24.3%) in August, and 38(25.7%) in September with a prevalence with the ages of the twenties to the seventies. Of a total 154 patients, the male were 86(58.1%) and the female were 68(41.8%). The annual parasite index(API) were 6.44, 5.89 and 4.45 in Songhaemyon, Yangsamyon and Kyodongmyon, respectively. A high infection rate was found Particularly in the areas within 2km from the Han river. By the immunofluorescence assays(IFA), 26 cases were positive with an antibody titers of $\geq$ 1 : 32, of 220 residents in Songhaemyon and 336 ones with a potential case and contacted with the patients. By the blood test, there was no significance in alkaline phosphatase, alanine aminotransferase, total cholesterol, glucose, hemoglobin, hematocrit, white blood cell, red blood cell, and platelet between residents with an antibody titers of $\geq$ 1 : 32 and < 1 : 32 in Songhaemyon.

미래의 해양 전장 환경에 대비하고 다양한 요구사항을 만족하기 위해 함정을 구성하는 여러 체계의 기능이 고도화되고 다양화되고 있다. 함정의 승조원 수는 제한되어 있어 결국 한명의 승조원이 담당하는 임무와 운용 화면의 수는 늘어나고 있다. 본 논문에서는 REST 아키텍처를 이용하여 함정 내 각 체계와의 연동을 통해 체계의 정보와 서비스를 자함 객체로 통합하고 HTTP와 JSON 기반의 API 형태로 제공하는 함정 통합 서비스 프레임워크를 제안한다. 그리고 이를 전투체계 테스트베드에서 구현하고 성능을 측정하여 해군함정에 적용 가능함을 입증하였다. 본 논문에서 제시된 프레임워크를 실제 함정에 도입한다면, 체계 간의 기능이 통합된 화면의 설계가 가능하게 되어 승조원이 효율적으로 함정을 운용할 수 있을 것이다.

Strain NK181 was isolated for probiotic use from jeotkal and based on results of API 50 CHL kit and 16S rDNA sequencing was tentatively named Lactobacillus plantarum NK181. L. plantarum NK181 was highly resistant to artificial gastric juice (pH 2.5) and bile acid and demonstrated strong adherence to Caco-2 cells. In test using API ZYM kit, eight enzymes were produced. Supernatant of L. plantarum NK181 exhibited about 30% 1,1-diphenyl-2-picyryl hedrazyl (DPPH) radical-scavenging activity and reduced cholesterol by 70%. These results demonstrate potential use of L. plantarum NK181 as health-promoting probiotic.

We have developed an information management tool for the EDISON (EDucation-research Integration through Simulation On the Net) open platform. EDISON is, at present, a web-based simulation service for education and research in five computational areas, namely, nanophysics, fluid dynamics, chemistry, structural dynamics, and computer aided optimal design. The EDISON open platform consists of three tiers: EDISON application framework, EDISON middleware, and EDISON infra-resources. The platform provides web portals for education and research in areas such as computational fluid dynamics, computational chemistry, computational nanophysics, computational structural dynamics, and computer aided optimal design along with user service. The main purpose of this research is to test the behavior of the release version of the EDISON Open-Platform under normal operating conditions. This management tool has been implemented using the RESTful API designed in EDISON middleware. The intention is to check co-operation between the middleware and the infrastructure. Suggested tools include User management, Simulation and Job management, and Simulation software (i.e., solver) testing. Finally, it is considered meaningful to develop a management tool that is not supported in other web-based online simulation services.

A disease with mass mortality characterized exophthalmia and abdominal distension by ascites occurred in farmed starry flounder, Platichthys stellatus in Pohang since October of 2007. Severe necrosis and infiltration of inflammatory cells were observed in tissue histopathological sections from liver, kidney, spleen and heart of the diseased fish. The catalase-negative and gram positive cocci with -hemolysis were isolated from moribund fish. Analysis of the API profiles and the multiplex PCR of the isolates showed that strains were identified as Streptococcus parauberis. In API profiles, S. parauberis isolated from starry flounder differed from those of olive flounder, Paralichthys olivaceus to the test of arginine dihydrolase, D-mannitol, D-sorbitol and α-lactose. And the strains, PH0710 and PH0711, were strongly lethal for starry flounder (LD50 ranging from 4.2×103~4.2×102 cfu/fish at 7 days after intraperitoneally inoculation). This is the first report on a S. parauberis infection in starry flounder.

The genus Proteus has been rarely isolated from cultured fish. In this study, we reported Proteus vulgaris isolated from fish skin lesion of Black-spotted porcupine fish (Diodon hystrix). Identification of f vulgaris was performed by general biological test, including API 20E and API ZYM. The sensitivity of isolated strains to different groups of antibiotics was evaluated using the disc diffusion method. It showed that the isolate is sensitive to ciprofloxacin $(5{\mu}g)$, norfloxacin $(10{\mu}g)$, enrofloxacin $(5{\mu}g)$, cefotaxime $(30{\mu}g)$.

Flavobacterium johnsoniae was isolated from farmed rainbow trout Oncorhynchus mykiss in Korea, and its biochemical and molecular characterization was determined. Yellow-pigmented bacterial colonies were isolated from 18 of 64 fish samples (28.1%) on trypticase soy agar plates, and their biochemical profiles were characterized by API 20E and API 20NE test kits. F. johnsoniae was identified by biochemical phenotyping of factors including rapid gliding motility, Gram-negative condition, oxidase- and catalase-positive status, Congo red absorption, nitrate reduction, ${\beta}$-galactosidase production, acid production from glucose, and gelatin and casein hydrolysis. PCR and subsequent sequencing of 16S rRNA confirmed that the yellow-pigmented colonies were most similar to F. johnsoniae. The alignment analysis of 16S rRNA sequences also showed that all 18 rainbow trout isolates had highly similar homologies (97-99% identity). One isolate was selected and named FjRt09. This isolate showed 98% homology with previously reported F. johnsoniae isolates, and in phylogenetic analysis was more closely grouped with F. johnsoniae than with F. psychrophilum, F. columnare, or F. branchiophilum. This is the first report on the occurrence and biochemical characterization of F. johnsoniae isolated from rainbow trout in Korea.

This study was investigated to isolate identify the total bacteria and fungi from the indoor air of work-place of the shoes, paint, stainless steel, and plastic industries. The number of bacterial colonies on the nutrient agar plates were calculated by the open petridish method for 30 minutes in indoor air of work-places at the autumn and winter. The isolated bacteria were identified by Gram stain and biochemical test using API Staph and API 20E kits. The isolated fungal colonies were identified by gross appearance of the giant colonies and microscopic examination of their spore and hyphal characteristics on the slide culture method. The minimum inhibitory concentration (MIC) of several antibiotics against isolated bacteria was determined by the microdilution method with Mueller-Hinton broth. The 70-400 colonies in autumn and 54-236 colonies in winter were isolated from the indoor air of work-places of several industry. The isolation rates of Gram positive cocci, Gram positive bacilli, Gram negative bacilli, and Gram negative cocci were 46.3%, 19.8%, 17.3%, and 16.1%, respectively. In Gram positive cocci, the most strains were identified as Aerococcus spp, Micrococcus spp, and Staphylococcus spp. In Gram positive and negative bacilli, and Gram negative cocci were identified as Bacillus spp, Pseudomonas spp, and Neisseria spp, respectively. The frequently isolated fungi were Aspergillus spp, Penicillium spp and Rhizopus spp, respectively. The frequently isolated Aerococcus spp, Micrococcus spp, and Staphylococus spp were highly resistance against ampicillin, erythromycin, methicillin, and tetracycline. These results arouse our attention to microbiologic pollution in the indoor air of work-places of industries.
