시설원예산물 중 DON 생성능이 있는 균주의 오염 여부를 조사하기 위해 진주를 비롯한 서부 경남 일원과 경북 안동 근교에서 총 192점의 시료를 분리하여 균 분리를 실시한 결과 Fusarium속 103균주를 분리하였다. 분리된 균을 YES배지로 $28^{\circ}C$, 15일 배양한 후 ethyl acetate로 추출하여 thin layer chromatography(TLC)법으로 확인한 결과 DON 생성 균주 8개가 확인되었다. Enzyme amplification system immunoassay법을 이용하여 DON 생성 균주 8개를 정량한 결과 검출범위는 $0.007-1.21\;{\mu}g/mL$ 이었다. 이 중 남해 토양에서 분리한 32-D-3 균주가 $1.21\;{\mu}g/mL$로 가장 높았다.

Purpose: The purpose of this study was to identify the influencing factors on osteoarthritis in Korean. Method: Data from the Fourth Korean National Health and Nutrition Examination Survey(KNHANESIV-3, 2009) were obtained, and 1,116 subjects who responded certainly yes or no to the question for osteoarthritis were selected. Data were analyzed ${\chi}^2$-test, t-test, and binary logistic regression using the SPSS V18.0. Results: Significant differences in gender, age, menopause, weight, BMI, frequency of walk, days of flexibility exercise, days of strength training, and limitation of activity were found between subjects with osteoarthritis and non-osteoarthritis. Age and BMI were found to be risk factors for osteoarthritis in Korean. Conclusion: This study suggested that nursing intervention should include weight control program for the obesity patient in order to reduce the prevalence of osteoarthritis.

Single serologic tests may occasionally influence clinicians in making diagnoses. The antistreptolysin O (ASO) test is a frequently used tool for detecting recent Streptococcus pyogenes infection and is helpful in the diagnosis of diseases like rheumatic fever. Using data from a 1989 prospective study of 600 healthy male military recruits, in which 43% experienced S. pyogenes upper respiratory tract infection (2-dilution rise in ASO), this report compared two methods of interpreting a single ASO titer. Using the 'upper limit of normal' (80 percentile) method, recruits with an ASO titer of greater than 400 showed evidence of recent S. pyogenes infection. This method had a sensitivity and specificity of only 65.9 and 81.9% respectively. In contrast to the 'yes-no'. dichotomy of the 'upper limit of normal' method. the likelihood ratio method statistics were ASO value specific, more consistent with clinical judgment, and better emphasized the caution clinicians must use in interpreting a single ASO test.

Purpose: Perceived barriers to exercise were investigated for adults. Method: A total 1266 subjects were selected by a quota sampling method with age, gender, and residence. Perceived barriers were categorized under 4 groups: knowledge, psychological, physical, and external factors. All 23 items of perceived barriers were responded on a dichotomous (yes/no) scale. Result: Mean number of perceived barriers was 4.61 and 87.9% subjects perceived at least one barrier which prevented involvement in exercise. External barriers ranked highest, followed in order by psychological, knowledge, and physical barriers. Most factors of perceived barriers were found to be different by age, gender, and residence, in that, the younger, female, living in Daejeon subjects were found to respond with more barriers than the older, male, living in Chungju or Seoul. Conclusion: Perceived barriers to exercise are differenct by age, gender, and residence. Therefore, it is recommended that age, gender, and residence of subjects must be considered in order to develop exercise programs and public campaigns.

The purpose of this study was to explain the performance pattern of health education and related factors in elementary school. The data were collected from school nurses who have been working elementary school. Sample of 77 were analyzed by percent distribution, ${\chi}^2$-test, discriminant analysis. The performance rates of health education was 74%, Only 19% of total carried out health education of 6 hours per week. Important variables that was showed significant association with health education level were as follows: Perception of importance about health education among personal characteristics of school nurses and size of school c1ass, cooperation level of school administrator, operation method of school health clinic, the difficulty of school health clinic among school organization characteristics. The canonical correlation between the health education (yes or no) and important independent variables was 0.52. Among them, operation method of school health clinic. perceiveness of health education, size of school class represented the significant contribution (canonical coefficient: 0.66, 0.54, 0.52) to school health education. These findings suggest that structure and management variables of school organization are more important than personal variables of school nurses related to activation of school health education. Therefore, it is expected that the quantity and quality improvement of school health education be able to accomplish through the systematic support of school organization and government demension.

최근 인터넷 환경에서 시스템 불법 침입은 계속적으로 증가하고 있다. 이러한 침입을 탐지하기 위한 기법들은 크게 비정상 탐지와 오용 탐지로 분류할 수 있다. 전자는 통계적 방법, 특징 추출 등을 이용하며, 후자는 조건부 확률, 전문가 시스템, 상태 전이 분석, 패턴 매칭 둥을 적용한다. 현재 연구된 침입탐지 시스템들은 결합된 방법을 사용하고 있다. 본 연구에서는 상태전이 기법과 연관 마이닝 기법을 결합한 새로운 침입 탐지 알고리즘을 제안한다. 이를 위해 첫 번째 단계는 네트워크를 통해서 입력된 명령어에 대해서 상태 테이블을 작성하는데, 이는 기존의 상태전이 분석 방법과 유사하다. 다음 단계는 연관 마이닝 기법을 이용하여 침입의 유형을 판정한다. 이러한 처리 과정에 따라 본 연구에서는 자동화된 침입 시나리오 생성 알고리즘을 제안한다.

In this paper, we place the focus on suggesting a method of forecasting demand for PCS resale service with survey data in Korea. It is important for the service provider to forecast the diffusion process when designing marketing strategies and analyzing the costs and benefits. For the reason, we conduct a survey of three groups composed of non-subscribers, cellular subscribers, and PCS subscribers in order to forecast the demand according to several possible scenarios and business strategies. We consider the survey item that is measured by multiple point scales in response to a question if he would subscribe to the mobile telephone service in the future. We propose a method to forecast the size of market potential by classifying each individual into the two extreme groups, that is, yes or no. Then, by integrating survey data and historical data, we forecast the demand for PCS resale service that varies according to scenarios and strategies. From the results, we can find several implications for the provider of PCS resale service.
