This study was attempted to investigate the properties of brucellosis in Korean indigenous cattle at the Yeongwol and Pyeongchang county. Brucella spp was differentiated and identified from cotyledons, amniotic fluids and supramammary lymph nodes which confirmed with clinical, serological, epidemiological evidences (69 cases) from January to June, 2004. Isolation frequency of this causative agent from supramammary lymph nodes, cotyledons and amniotic fluids from 38 pregnant Korean indigenous cattle were $39.1\%,\;87.5\%,\;and\;63.2\%$, respectively, and finally confirmed with Brucella abortus biotype 1 through biochemical and serological test. A Brucella specific DNA with 711bp band was detected by PCR assay using BCSP primer. The two cases were definite epidemiological evidences that infected Korean indigenous cattle acrossed the border to Yeongwol and Pyeongchang from near two provinces. Effective prevention programs are urgently needed for further spreading this epidemics.

Purpose: The purpose of this study was to evaluate the current level of sleep quality among Korean middle-school students using the Pittsburg Sleep Quality Index (PSQI), and to analyze the factors influencing sleep quality. Methods: The study used a descriptive cross-sectional design and a self-report questionnaire. The participants were 744 middle-school students. The questionnaire included the PSQI and health-related questions, such as the types of diseases they had been diagnosed with and the frequency of hospital admissions. The data were analyzed using the independent t-test, analysis of variance, Pearson correlation coefficients, and linear multiple regression. Results: The global PSQI score was 4.21, which indicated good sleep quality. The major factors that were associated with the sleep quality of middle-school students were the number of diseases they had been diagnosed with (β=.54, p=.001) and atopic dermatitis (β=.32, p=.001). In addition, asthma and the frequency of hospital admissions were significant factors influencing each component of the PSQI. Conclusion: The findings from this study suggest that sleep quality was associated with several health-related factors. Thus, nurses, school nurses, and nursing researchers may need to assess the health-related factors associated with adolescents' sleep quality as part of efforts to improve their sleep quality.

The purpose of this study was to evaluate the polymorphism in parotid middle-band protein(Pm) of the patients with diabetes mellitus. Saliva from the parotid glands was collected from 60 healthy Korean who were live in Kwan-ju and from 33 diabetes mellitus patients who had more than 140mg/dl of fasting blood sugar for on week. In the saliva collected from parotid glands, Pm was analyzed to evaluate the distribution of phenotype using acid-urea starch gel elecrophores is The following results were obtained : 1. The phenotypes of parotid middle band protein(Pm) observed in parotid saliva of the control group(60 people) were Pm(+) in 38 people (63.3%) and Pm(-) in 22 people (36.7%). The gene frequency of Pm+ was0.394, and that of Pm- was 0.606. 2. The phenotypes of parotid middle band protein(Pm) observed in parotid saliva of the diabetes mellitus patient group(33 patients) were Pm(+) n 21 patients(63.6%) and Pm(-) in 12 patients (36.4%). The gene frequency of Pm+ was 0.397, and that of Pm- was 0.693 3. Pm dose not have significant differences between phenotypes on both the control group and the diabetes mellitus patient group.

Species composition and community structure of marine benthic community were studied in the intertidal zone of Jijindo Island, Gwangyang Bay. A total of 85 species of benthic marine plants including the 5 Cyanophyta, 9 Chlorophyta, 13 Phaeophyta, 56 Rhodophyta and 2 Magnoliophyta that were listed. The community structure was represented by Gelidium divaricatum in the upper zone, Celidium divalicatum and Ulva pertusa in the middle, and Ulva pertusa, Chondria crassicaulis, Chondracanthus intermedia and Sargassum thunbergii in the lower intertidal zone. The dominant species in the rnscro-zoobenthic community were Chthamalux challengeri in the upper and middle, Littorina brevicula between the upper and middle, and Mytilus edulis and Crassostrea gigas in the middle and lower intertidal zones. The economic benthic organisms such as Undaria pinnatifida, Mytilus edulis, and Crassostrea gigas found in the lower intertidal zone were frequently disturbed due to their collection by local resident. Therefore, it is necessary to record the correct information pertaining to these cases. The species diversity indices estimated kom different sources were quite different. They were 2.22 derived from frequency, 1.67 based on coverage, 2.17 based on sum of frequency and coverage and 2.04 derived from importance value. Species diversity and number of algal species in Gwangyang Bay have noticeably decreased, compared with their previously reported status. It is estimated that their decreases were caused by changes in the marine environment, especially pertaining to the polychaete community resulting from reclamation and dredging activity undertaken for the industrial development.
