RAPD를 이용하여 국내에 생육하는 4종의 자생 민들레와 2종의 귀화 민들레 종간의 유전적인 유연관계를 분석하였다 Primer Screening을 통해 선발된 30개의 Primer를 이용하여 RAPD를 행한 결과, Polymorphic band 수는 141개로 나타나 민들레 종간의 유전적인 차이 분석이 가능하였다. Primer OPC12, OPD16, OPK16, OPK17, OPK20, OPSI에서는 각 종마다. 특정 밴드가 있는 것으로 조사되었다. 특히 OPS8에서는 564bp에서 귀화종인 서양민들레 종에서만 특이 밴드가 나타났다. RAPD분석결과 자생종과 귀화종 민들레들은 명확히 2군으로 구분되었다. 1군에는 서양민들레. 붉은씨서양민들레 등의 귀화종 그룹이었으며, II군은 민들레, 산민들레, 좀민들레, 횐민들레 등의 자생종 민들레 그룹으로 나뉘어졌다. Bootstrap 방법으로 6종의 유연관계를 분석한 결과도 비유사계수를 통한 방법으로 분석한 결과와 매우 유사하였다 우리 나라에서 자생하는 민들레속 6종의 주요형질을 조사한 결과 I군에 속하는 민들레류는 II군에 속한 종들에 비해 개화일수가 길고, 외총포편의 방향이 다르며 털의 유무 또한 다른 특징이 있었다. ll군에 속하는 횐민들레는 다른 민들레종과는 화색에서 확연한 차이를 보였으며 자생종들 속에서도 잎의 방향과 발아의 생리적 특성 등 유전적으로 여러 다른 점이 복합적으로 작용함으로서 II군내에서도 유전적 거리가 가장 먼 것으로 나타났다.

This study was aimed to establish the evaluating protocol and standard assessment for genetically modified (GM) hot pepper and to find out a proper statistic method to analyze for equality of agricultural characters between GM and non-GM pepper lines. GM and non-GM hot pepper lines were cultivated in two GMO fields in the middle region of Korea and total of 52 agricultural characters were collected during the plant growing season for 4 years, 2007 to 2010. Levene’s test was conducted to confirm the homogeneity of raw data before statistic analysis. Two-way ANOVA in the multivariate tests and t-test were conducted to analyze 52 agricultural characters in order to find out the equality between H15 and P2377. From the statistical analysis through two-way ANOVA, 16 out of 16 plant growth traits, 9 out of 18 green fruit traits and 7 out of 18 red fruit traits among 4 years and 9 out of 16 plant growth traits, 4 out of 18 green fruit traits and 3 out of 18 red fruit traits between H15 and P2377 have shown the statistic differences. With the same raw data of 52 agricultural characters, t-test was also conducted. Based on the result from t-test, only 1 out of 16 plant growth traits, 2 out of 18 green fruit traits and 1 out of 18 red fruit traits have shown the differences between H15 and P2377, so that it was concluded that there is no statistic difference between H15 and P2377 in terms of agricultural characters. Also, the t-test is a proper statistic method to analyze each trait between GM and its control lines in order to evaluate agricultural characters.

Questionnaires were distributed to Radiology departments at hospitals with 300 sickbeds throughout the Pohang region of North Gyeongsang Province concerning awareness and performance levels of infection control. The investigation included measurements of the pollution levels of imaging equipment and assistive apparatuses in order to prepare a plan for the activation of prevention and management of hospital infections. The survey was designed to question respondents in regards to personal data, infection management prevention education, and infection management guidelines. The ATP Public Heath Monitering System was used to measure seven items for pollution levels of imaging equipment and assistive apparatuses in the Radiology Department. Data was analysed using SPSS version 12.0 for paired t-test and Pearson coefficient with a statistically significant level of 0.05. The results of the survey showed a total awareness level of infection management prevention education averaged at 3.73 ± 0.64 and performance levels resulted at 3.39 ± 0.83 which were statistically significant (p = 0.01). Also the measurements of pollution levels for equipment with high patient contact showed a Pearson Coefficient of over 0.5 implying a focus on pathogenic bacterium. There was no statistical significance with the frequency of imaging (p < 0.05). Therefore for general hospitals with high patient contact, there is a need to supply analyzing equipment for real time monitoring and the implementation of disinfection management that uses a Ministry of Health and Welfare approved antiseptic solution twice every minute.
