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.

We prospectively analyzed the corneal topography of 26 eyes in 26 patients who had undergone scleral expansion for correcting presbyopia. We examined 26 eyes of 26 patients which were devided into 2 groups (mean age: 51 years, range 40-60 years) according to type of scleral expansion band, with computerized corneal topographic analysis system. Preoperatively and 5 times postoperatively (1day, 1week, 2weeks, 1month, 2months), quantitative descriptors of corneal topograpgy such as Sim K (simulated keratometry value), SRI(surface regularity index), and SAI(surface asymmetry index) were measured at each visit. The mean follow-up period was 43 days. Sim K of the operative eyes ranged from 0 to 2.5 (mean, 0.93) before operation, and mean 2.24 at postoperative 1 day in group Ⅰ. In group Ⅱ, Sim K was mean 2.20 at postoperative 1 day and decreased thereafter. SRI was from 0.54 to 1.39 and SAI was from 0.09 to 0.45 before operation. After operation, mean SAI was maximum at postoperative 2 week and mean SRI was maximum at postoperative 1 day and decreased thereafter. After two months, it became minimum. This study demonstrates that quantitative topographic change after scleral expansion for correcting presbyopia were great during first 1 week after surgery but this change diminished thereafter. Further long studies are in progress to evaluate the long term effects of this procedure.

The object of these analyses is to calculate stretching forces of inter changeable shadow mask inside the perfect flat monitor. There are millions of holes in a shadow mask. For the realistic finite element analysis, effective elastic modulus and Poisson ratios are calculated using unit cells. The linear superposition of load cases is used to determine the optimum stretching forces for uniform strain field in a mask array. The finite element analysis results are good agreement with test results.

노지에서 비적기재배를 위한 재배연도 및 파종기(4월 15일-조파, 5월 15일-적파, 6월 15일-만파)에 따른 유색콩(대추밤콩, 검정콩1호, 진주1호, 푸른콩)의 생육 및 수량형질의 특성과 유전력을 조사하여 특수콩 품종육성 및 재배 생리적 특성에 대한 기초 자료를 제공하고자 2001년부터 2002년까지 수행한 시험 결과는 다음과 같다. 1. 파종기에 따른 경장은 조파에서 만파로 갈수록 감소하였고, 경직경과 주경절수는 조파와 적파에 비해 만파에서 적었다. 품종에는 경장, 경직경, 주경절수 모두 푸른콩이 가장 크고 굵고 많았다. 2. 분지수와 분지절수는 조파에서 만파로 갈수록 감소하였으며, 분지수는 품종간 차이가 없었고, 분지절수는 푸른콩이 가장 많았다. 3. 100립중은 조파에서 높았으며, 품종 중에는 대추밤콩이 가장 컸고, 진주1호가 가장 작았다. 입중과 10a당 종실수량은 조파에서 만파로 갈수록 감소하였으며, 입중은 검정콩1호가 가장 무거웠고, 10a당 종실수량은 대추밤콩이 가장 많았다. 4. 생육형질의 유전력은 경장이 92%로 가장 높았으며, 수량형질은 100립중이 99%로 가장 높았다. For two years, from 2001 to 2002, this experiment was conducted to investigate growth and yield characters as influenced by different planting dates and cultivation years in order to non-optimal cultivation at field in colored soybean. Varieties used in the experiment were four varieties such as Daechubamkong, Pureunkong, Geomjeongkong 1, and Jinju 1. These varieties were planted on April 15 (early planting), May 15 (optimum planting), and June 15 (late planting), respectively. Stem height rep-resented by different planting dates as early, optimum and late planting had gradually decreased from early to late planting and stem diameter and number of stem nodes were lower in late planting than in early and optimum plantings. Stem height, stem diameter, and number of stem nodes were the tallest, the thickest, and the most Pureunkong of varieties. The number of branches and number of branch nodes had gradually decreased from early to late planting. The number of branches of all varieties was not different and the number of branch nodes was largest Pureunkong of varieties. One hundred seed weight was higher on April 15 as early planting and Daechubamkong was the highest among varieties whereas Jinju 1 was the smallest. Seed weight and seed yield per ten are had gradually decreased from early to late planting. Seed weight was the heaviest Geomjeongkong 1 of varieties and seed yield per ten are was the largest Daechubamkong of varieties. Heritability mean in growth characters tested for two years was the highest in stem height that was 92%. Heritability mean in yield characters was the highest in one hundred seed weight which was 99%.

박재선,박두병,이길홍 大韓神經精神醫學會 1989 신경정신의학 Vol.28 No.4

The present study was to examine the relationship between psychiatric inpatients' occuputions and their anxiety level. The sampling subjects were randomly selected by 3 stage probability proportional culster extraction method among psychiatric who were admitted to the psychiatric clinics and hospitals nationwide. Four hundred and twenty eight subjects including 249 males and 179 females were undergone by questionnaire survey while measurement of anxiety was done by using Zung's self-rating anxiety scale. Collected data were processed by IBM PC AT computer using SPSS program and statistically analyzed by chi-square test and analysis of variance. 1) It was revealed that these psychiatric inpatients showed relatively higher rates of the unemployed (34.6%), single(43.2%), and divorce(5.1%). 2) Patients with higher classes of occupation such as administrative, managerial or clerical workers showed higher rate of divorce. 3) In the occupational distribution of psychiatric disorders, psychotic disorders were more prevalent among high or low occupational classes, neurotic disorders more prevalent among middle occupational classes, while psychoactive substance use disorder more prevalent among farmers and sales workers. 4) Overall the mean anxiety score of the whole subjects is 39.28 ±14.67. The mean anxiety score (39.71±14.89) of the pschiatric inpatients with job is higher than that (36.59±14.20) of the unemployed. 5) In the anxiety tendency according to occupational classification, the unemployed showed less anxiety compared with the employed. Patients with middle occupational classes such as fishing workers and sales workers showed higher levels of the cardiovascular, musculoskeletal, respiratory and skin system anxiety, while patients with higher or lower occupational classes showed lower anxiety. In the relationship between occupational classes and level of anxiety, it showed profiles of inverted V curve. 6) The lower occupational classes such as sales workers showed higher anxiety level, while the higher occupational classes such as clerical workers showed lowest one. Particularly the fishing group exposed in the higher stress situation showed the highest level of anxiety.

박시호,권영식,이길재 韓國敎員大學校 敎育硏究院 2009 敎員敎育 Vol.25 No.3

본 연구는 제7차 교육과정이 적용되고 있는 중학교 3학년,고등학교 3학년 그리고 교사를 대상으로 우성과 열성,불완전 우성,완전 우성,공우성에 대한 개념에서 나타나는 오개념을 알아보고자 하였다. 중학교 3학년 264명,고등학교 자연계열 3학년 학생 103명,생물 교사 53명의 응답을 분석하였다. 이 연구의 결과에 따르면,특히,학생과 교사 모두 우성은 '열성을 억제하고 표현되는 형질이다.' 열성에 대해 학생들은 '부모로부터 유전자를 전달받지 못하여 나타난다.’라는 오개념 비율이 높게 나타났다. 둘째,중학생의 24.4%, 고등학생의 19.4%가 '교배 결과 많이 출현하는 형질이 우성이다.’라는 오개념을 가지고 있었다. 셋째,중학생의 48.1%. 고등학생의 36.9%가 '열성은 생활에 불리하거나 우성이 우수한 형질이다.’라는 오개념을 가지고 있었다. 넷째,완전 우성,불완전 우성,공우성에 대해 교사와 학생 모두 높은 비율의 오개념을 가지고 있었다. 이 연구를 통해 교사는 교육을 실행하는 동안 '우성이 열성을 지배한다’ '억제한다’ '누른다’ 등의 표현은 사용하지 않는 것이 타당할 것으로 생각된다. 또한 개체 수준의 전달 유전과 분자 수준의 형질 발현과정을 통합하는 수업전략이 필요함을 알 수 있었다. The purpose of this study was to analyze the misconceptions of definition of dominance and recessive traits, law of dominance, incomplete dominance and codominance which middle and high school students and teachers have. For this purpose, we analyzed a questionnaire of 103 natural science students in the third grade and 264 middle school students in the third grade and 53 biology teachers. According to the results of analyzing the questionnaires, most of the students and teachers had various misconceptions on the concepts of dominance. Expecially, They had the misconception that 'dominance is controls completely recessive and then it is expressed' and the students about recessive characteristic shows because of gene isn't handed down from parents to progeny. Second, 24.4% of middle school students and 19.4% of high school students had the misconceptions many expressed trait is dominance. Third, 48.1% of middle school students and 36.9% of high school students had the misconceptions the recessive characteristic have a disadvantage in life or the dominance is predominance characteristics. Fourth, most of the students and teachers had very high misconceptions on complete dominance, incomplete dominance and codominance. According to this study, such expressions as 'dominant characteristics governs, controls, or suppresses recessive characteristics,' don't have to use in lessons of gene. Lessons for middle and high school students need to integrate transmission heredity at the object level and the process of characteristics expression at the molecular level.
