The objectives of this study, an analysis of the variation for leaf and fruit characteristics among the selected ten populations of Sorbus commixta Hedl. could be used for the conservation of gene resources and could provide information to superior trees selection. The results obtained from this study can be summarized as follows; Approximately, the Mt. Sungin population at Ulleung island showed larger values in overall characteristics and populations. On the other hand, Mt. Halla population at Jeju island showed the smaller values of the overall characteristics and populations. ANOV A tests showed that there were statistically significant differences in all leaf characteristics among the populations as well as individual trees within populations. But, for fruit characteristics, differences were statistically significant only among the populations. Cluster analysis using single linkage method based on leaf and fruit characteristics showed that ten selected populations of S. commixta in Korea could be clustered into three groups. Group I is Mt. Sungin at Ulleung island, Group II is Mt. Halla at Jeju island, and Group III comprises Osan, Mt. Kaji, Mt. Duckyoo, Mt. Balwang, Mt. Sobaek, Mt. O-dae, Mt. Jiri, and Mt. Taebaek. The selection level based on major agronomic traits, which are the Number of Fruit per Fruiting Lateral(NFL) over 50, and Fruit Length(FL) and Width(FW) over 10 mm, and Weight of 100 Fruit(WFI00) over 66 g, was applied on 100 sample trees, and five trees were selected. The selection effects from selected trees in NFL, FL, FW, and WF100 were evaluated as 132%, 151 %, 142%, and 264% compared to the mean of those 100 sample trees, respectively. Especially, Ulleung 2 showed excellent values that NFL and WFI00 were 95, and 69 g, respectively, suggesting a promising new cultivar for larger fruit and high productivity.

Diabetic foot infection is one of the important complications in patients with advanced diabetes mellitus. Limb threatening infections such as osteomyelitis, abscess, and necrotizing fasciitis are frequently accompanied by the disease. Non-tuberculous mycobacterium (NTM) is a rare causative organism of diabetic foot infection. Thus, if one is not suspicious or meticulous, infection due to NTM will be easily overlooked and this will result in delayed diagnose and treat. Therefore, it is necessary to consider NTM as the causative organism if the wound does not respond to the conventional antibiotic treatment and the culture from the adequately obtained specimen reveals atypical acid-fast bacilli. We present a case of diabetic foot infection with osteomyelitis and abscess due to Mycobacterium mageritense, one of the rapid growing mycobacteria, that was successfully treated with surgical debridement and appropriate antibiotic treatment.

미래 사회를 대비하기 위한 개인의 개성을 존중과 창의적인 능력을 지닌 인간을 양성을 목적으로 충청남도 지역의 초 ㆍ 중고등학생들을 대상으로 한 창의력 경연대회가 공주대학교 과학교육연구소에서 개최되었다. 충청남도 초 ㆍ중 ㆍ 고등학생들을 대상으로 실시한 창의력 경연대회는 창조적 아이디어를 내어 스스로 문제를 해결해 나갈 수 있는 교육 프로그램을 제공하는 좋은 기회였음이 확인되었으나, 일부의 팀에서만 참신하고 재미있는 아이디어들이 제안되었다. 여학생의 참가자 수가 상당히 증가하였으며, 대체적으로 입상권의 학생들의 상당 부분이 여학생이라는 것이 특이할만하다. 학년이 올라감에 따라서 창의적인 아이디어를 내는 양이나 질에 있어서 뒤떨어지는 것으로 분석되었으며, 토론 학습의 적응력이 미흡하고 발표력 및 청취력에 있어서도 떨어지는 것으로 나타났다. 따라서 중 ㆍ고등학교의 학교교육에서도 학생들에게 프로젝트형 탐구학습 프로그램의 적용은 물론 토론식 수습을 통한 학생들의 사고의 전환의 기회를 제공해야 할 것으로 사료된다. The creativity competition was held to foster the creativity of elementary and secondary school students in the Institute of Science Education, Kongju national University. It was found that the creativity competition effected on the improvement of inventing creative ideas and problem solving activities. But, only some competitors participated in semifinal and final contests, presented original and interesting ideas. More female students participated in competition than last year. More female participants were awarded a prize than males. Totally, participants were defective in discussion and communication, and presentation and listening ideas. Increasing grades correlated inversely with creativity and originality. There is need of inquiry project teaming programs and presenting opportunities of conversion of thinking by discussing instructions in school

Background and Objectives: This study was performed to evaluate the usefulness of early operation in children with traumatic subdural hygroma. Materials and Methods: The subjects were eleven patients (Glasgow coma scale (GCS) score was below 10 and age was below 10 years old) who developed subdural hygroma after trauma between January 2000 to December 2002. Subduroperitoneal shunt was performed in one group and not performed in the other group. We analyzed the GCS score on admission and at 1 year after operation. Overall clinical results were evaluated retrospectively. Results: Patients who underwent operation exhibited higher GCS scores at 1 year after trauma compared to those in the patients who were treated by conservative therapy (p<0. 05). Conclusion: The early operation could be an effective treatment to children with subdural hygroma who showed delayed improvement of consciousness and to patients with hygroma that didn't decrease or was above moderate amount.

Backgroud : Drug resistant virus has been seen with all effective antiretroviral drugs in current practice. The isolation of resistant virus from subjects is associated with more rapid clinical outcome. The presence of resistance-conferring mutations in a patient in whom therapy is foiling indicates that other antiretroviral drugs should be considered. So, the identification of drug resistant Human Immunodeficiency Virus (HIV-1) mutations is of increasing importance. Zidovudine monotherapy for HIV-1 infection has been widely used in Korea since 1990. So, the prevalence of zidovudine resistant virus has been expected to be high. The purpose of the present study is to determine the prevalence of zidovudine resistant HIV-1 among zidovudine-naive Korean patients. Methods : We tested drug susceptibility of HIV-1 isolated from 19 zidovudine-naive Korean patients. We amplified a portion of gene reverse transcriptase of HIV-1 by RT nested PCR method. The susceptibility of HIV-1 to zidovudine was determined by sequencing the DNA base pairs of gene reverse transciptase. Results : Two (10.5%) of 19 HIV-1 isolates from zidovudine naive patients showed resistance conferring mutations to zidovudine. Two (2.1%) of 95 codons analysed from zidovudine naive patients showed mutations conferring resistance to zidovudine. Conclusion : The prevalence of zidovudine resistant HIV-1 was 10.5% among zidovudine-naive Korean patients. (Korean J Infect Dis 33:40~45, 2001)

This study was undertaken to grasp health-promoting behavior of the elderly and to identify self-rating health status, demographic characteristics related to them in order to facilitate nursing intervention for health promotion of the population. The subjects for this study were 225 old persons visiting five general social welfare centers located in Tague. Data were collected by self-reported questionnaires from August, 2002to February, 2003. Questionnaires were Northern Illinois University's Health Self-Rating Scale, Walker and others' health Promotion Lifestyles Profile. Analysis of the data was done by the SAS program for descriptive statistics, t-test, ANOVA, and pearson Correlation Coefficient. The results were summarized as follows: 1. There were significant differences in health-promoting behavior according to sex)t=3.28, p=.0011), marital status(F=8.98, p=.0003), and average monthly pocket money(F=4.99, p=.0007). 2. For the participation in health-promoting behavior, the mean score was 2.96 and range was from 3.40 to 2.34. The factors of high mean score were sedentary life(3.40), regular diet(3.37), and factors of low mean score were stress management(2.34), accountability for health(2.60). 3. The mean score of health self=rating was 2.19(range 4-14) and was considered low. 4. Self-rating health status was correlated positively with health-promoting behavior(r=.1783, p=.0106). On the basis of the above findings, the followings are recommended; 1. Nursing strategies need to be developed considering personal demographic characteristics of the elderly. 2. Nursing interventions enhancing self-actualization, accountability for health, stress management of the elderly must be provided.

이 연구에서는 장파 (Chou et al., 1994) 및 단파(Chou, 1992)복사 모델을 이용하여 중위도 겨울철 조건하에서 구름의 고도, 구름의 중첩이 대기 가열 및 냉각율에 미치는 영향을 조사하였다. 모델의 입력자료로 사용한 중위도 평균적인 기온, 비습, 오존의 구조는 McClatchey et al.(1972)로부터 얻었다. Based on the longwave and shortwave radiation model, the effects of cloud height and overlapping on the atmospheric heating and cooling rate was studied in midlatitude winter condition. The vertical profiles of air temperature, specific humidity, and ozones was obtained from McClatchey et al.(1972).
