In this study, a vehicle vector using cryptic plasmids was constructed for gene transfer in Helicobacter pylori. pHP51(3.9 kb) and pHP489(1.2 kb) were selected for constructing vectors from cryptic plasmid of H. pylori isolates in Korea. The HindⅢ-digestedDNA fragment(1.2kb) of pHP489 and 1.6kb DNA fragment of pHP51 were ligated with a kanamycin resistance gene(aph3'-Ⅲ) from C. jejuni to produce the recombinant plasmids pHP489K and pHP51K, respectively. Transformation frequency of pHP51K by electroporation was low. But pHP489K could be effectively transformed into various H. pylori strains. In order to design an intermdiate vehicle vector for gene transfer into H. pylori, pBlueHP489K was prepared by recloning pHP489K DNA into pBluescript and pTZ19R vector. This vector permitted the DNA fragment containing pHP489 sequence, aph3'-Ⅲ, and cloned DNA to be cut and self-ligated in the SacⅠ site after cloning. ureA and ureB gene were inserted into pBlueHP489K, resulting in pBlueHP489K/AB. The DNA fragment containing pHP489, kanamycin resistance gene(aph3'-Ⅲ), and urease structural gene was cut away from pBlueHP489K/AB and self-ligated to generate pBlueHP489K/AB. pBlueHP489K/AB made urease-negative H. pylori strains restore their urease activity. By this experiment, pBlueHP489K was confirmed to be the vehicle system for transferring H. pylori genes.

As a result of the enlarging pool of unvaccinated children and young adults, there has been an increase in measles in our countries. In these situation, it has been reported that measles associated pneumoinia is easily complicated with fatal respiratory failure, espycially in immunocompromised patients. Herein we report the case of lethal measles pneumonia after allogenic hematopoietic stem cell transplantation in adults proven by autopsy. Recently, one case of measles was encountered in 39-year-old female patients after allogenic bone marrow transplanted case (chronic myelogenous leukemia), who progressed into interstitial pneumonia pattern, despite treatment including antibiotics, immunoglobulin. The patient died of giant cell pneumonia compatible with that of measles which was comfirmed in the section of necropsy lung specimen. (Korean J Infect Dis 33:301∼309, 2001)

超急冷法에 의한 非晶質薄膜의 合成과 熱特性硏究

白彩鉉,趙映球 三陟大學校 1993 論文集 Vol.26 No.-

非晶質薄膜의 合成과 그 薄膜의 熱的特性에 關한 硏究는 많은 흥미와 注目의 對象이 되고있다. 그런데 Electrochyromism 特性을 갖는 MoO₃, WO₃는 單獨으로는 非晶質薄膜이 形成되지 않고 여기에 alkali를 첨가하면 비로소 일정한 mole비의 領域에서 晶質薄膜이 形成되거나, 또는 超急冷法의 方法을 사용할 때에 可能하다. 本 硏究는 超急冷法을 사용하여 MoO₃- WO₃계에 alkali대신 Al₂O₃를 첨가시켜 Al₂O₃- MoO₃- WO₃三成分系 非晶質薄膜을 合成하고, 이 系에 대한 物性을 檢討하였다. 이 때 Al₂O₃의 첨가로 이 薄膜이 熱的으로 安定化 되었고 IR-spectrum의 Ptern은 Alkali를 함유할 때 比하여 正常的인 spectrum이 얻어지지 않았고 Al₂O₃- MoO₃- WO₃三成分系로 되는 Glass化 領域은 Al₂O₃10-25 mole(%),MoO₃0~10 mole(%), WO₃75~85 mole(%)의 範圍에 존재함을 알 수 있었다. The study on the amorphous film synthesis and the thermal characteristic of that film has became the object of public attention and interesting a lot. However, MoO₃, WO₃with the charactersistic of electrochyromism independently couldn't make the amorphous film, when the addition of alkali in here, the amorphous film can form in the limits of the constant mole ratio or by using super cooling method. This study synthesized the amorphous film of ternary component system Al₂O₃- MoO₃- WO₃, adding as Al₂O₃instead of alkali to the system MoO₃- WO₃by supper cooling method, and then investigated the physical properties of this system. At this time the film was stabilized in thermal on account of the addition of Al₂O₃and the patern of IR-spectrum resulted in failure, an abnormal spectrum, by comparision the addition of alkali. Glasses in the tenary component system Al₂O₃- MoO₃- WO₃were showed 10-25 mole% of Al₂O₃0~10 mole% of MoO₃and 75~85 mole % of WO₃in limits.

연구목적 : 청소년을 대상으로 장애가 있는 식이태도 및 식이행동과 관련된 요인들에서 인종과 문화적 차이가 있는가를 보는 것이다. 방 법 : 1996년도에 3129명의 중고등학교 남녀 학생을 대상으로 학교 장면에서 신체 계측과 설문지를 통하여 수집하였으며 연령은 13세부터 16세 사이의 학생들로 분포되었다. 학생들의 분포는 서울 지역의 663명, 양평 지역의 821명, 조선족이 사는 연길 지역의 830명 그리고 한족이 사는 길림 지역의 815명이었으며, 그들은 모두 키, 몸무게, 신체질량지수, 부모의 수입, 아버지의 학력, 체중조절 설문지, 신체상 척도 및 식이태도검사 등의 내용을 완성하였다. 결 과 : 신체질량지수(BMI)에서는 지역, 성별, 사회경제적 상태에 따른 차이가 없었다. 연길과 길림 지역의 학생들이 서울과 양평 지역의 학생들보다 심한 저체중과 심한 과체중을 갖는 학생들이 많았다. 연길과 길림 지역의 학생들이 서울과 양평의 학생들보다 식이태도검사(EAT-26)의 평균치가 높아 식이태도와 식이행동이 나빴다. EAT-26의 20점 이상인 식이장애의 고위험군은 연길 지역의 학생이 6.9%로 네 집단 중에서 가장 많았다. 한국의 양평지역과 서울 지역의 학생들이 신체상 척도(BIS)의 평균치가 연길 지역과 길림 지역의 학생들보다 의미있게 높았다. 즉 한국의 학생들이 중국의 학생들보다 자신의 신체에 대하여 부정적인 생각을 갖고 있었다. 체중조절 행동의 유병율은 서울 지역 학생들이 26.7%, 양평 지역 학생들이 23.2%, 연길 지역 학생들이 10.6%, 그리고 길림 지역 학생들이 4.6%이었다. 식이조절과 운동은 한국의 학생들이, 식이조절과 약물사용은 중국의 학생들이 가장 많이 하는 방법이었다. 결 론 : 본 연구를 통하여 한국과 중국에서도 식이장애가 결코 적지 않을 것이라는 사실을 확인하였고, 식이장애는 인종과 사회문화적 요인에 의해 크게 영향을 받는다는 것, 마지막으로 식이태도와 식이행동 및 그와 관련된 요인들을 통해서 네 지역간의 문화전이 상태를 확인할 수 있었다. Objectives : The goal of this research was to attempt to examine ethnic and cultural differences in factors associated with disordered eating attitudes and behaviors. Methods : Data were collected from the four groups of 3,129 high school students aged between 13 and 16 years who completed school-based survey conducted in 1996. The students (663 Korean urban, 821 Korean rural, 830 Korean-Chinese and 815 Chinese adolescents) completed an instrument which assessed weight, height, Body Mass Index(BMI), parental income, father's level of education, weight control questionnaire, Body Image Scale(BIS), and eating attitudes and behaviors using the Eating Attitude Test-26(EAT-26). Results : BMI did not vary significantly by race, sex, and socioeconomic status. There were many severely underweight and severely overweight students among Korean-Chinese and Chinese than among Korean urban and Koran rural students. The EAT-26 mean scores of Korean-Chinese and Chinese subjects were significantly higher than those of Korean urban and Korean rural subjects. The EAT-26 mean score of Korean-Chinese was the highest among the four racial groups. The prevalence of high risk EAT-26(EAT-26≥20) students of Korean-Chinese was 6.9% which was the highest among the four groups. The BIS mean scores of Korean rural and Korean urban subjects were significantly higher than those of Korean-Chinese and Chinese subjects. The Korean subjects were more dissatisfied with their body than the Chinese. The prevalences of weight control behaviors were 26.7% in Korean urban, 23.2% in Korean rural, 10.6% in Korean-Chinese, and 4.6% in Chinese subjects. Dieting and exercise were most popular for weight reducing in Korean subjects. Dieting and drug use were most popular in Chinese subjects. Conclusion : These data suggest that there must be many eating disorder patients in Korea and China, and the eating attitudes and behaviors are influenced by ethnic and cultural factors. Implications for understanding sociocultural influence on eating attitudes and behaviors and acculturation are discussed.

강영규,김현우,백기청,이경규,임명호 大韓神經精神醫學會 2002 신경정신의학 Vol.41 No.6

연구목적 : 본 연구에서는 근래에 와서 건강을 위협하는 중요한 변인으로 강조되고 있는 흡연이 어떤 심리적 요인과 관련이 있는지 검증하고자 하였다. 여러 가지 심리적 변인 중 아마도 흡연과 가장 관련이 높을 것으로 생각되는 우울, 불안 그리고 충동성 정도가 흡연자와 비흡연자 간 뿐 아니라, 같은 흡연자라 할지라도 성별에 따른 차이가 있는지 검증하고자 하였다. 이러한 연구는 흡연을 예방하고 치료하는 데 있어 다른 물질중독의 경우와 마찬가지로 우울, 불안 및 충동성 등의 심리적 요인의 고려가 중요한 변인으로 간주되어야할 지를 알 수 있는 지표가 될 수 있을 것이다. 방 법 : 이 연구는 크게 BIS-11의 신뢰도 검증을 위한 예비연구와, 흡연과 정신건강과의 관계를 알아보기 위한 본 연구로 대별될 수 있다. 예비연구의 대상으로는 BIS-11을 한글로 번역하고 그 신뢰도를 측정하기 위해 일반인 187명을 대상으로 한 설문작업이 이루어졌으며 이중 30명에 대해서는 1주일 간격의 검사-재검사의 과정을 거쳤다. 본 연구의 연구대상으로는 천안 소재의 대학생 총 550명을 대상으로 하였다. 본 연구에 사용된 설문지는 ① 사회인구학적인 변인에 대한 문항들 ② Barrat 충동척도 임시 번안판 ③ Beck의 우울증 척도 한글판(Beck Depression Inventory : BDI한글판) ④ 상태-특성 불안척도 한글판(State-Trait Anxiety Inventory) 중 특성불안 척도 이렇게 총 4개의 부분으로 구성되었다. 통계분석은 SPSS Win 9.0을 이용하였으며 주로 이원변량분석법(Two-Way ANOVA)과 independent T-test 등을 이용해 분석하였다. 결 과 : 흡연군이 비흡연군에 비해서 'Barrat 충동척도 임시 번안판' 총 점수, 그 하위 3개요인 중 즉흥성(제 2 요인), Beck의 우울증 척도 점수 그리고 이들을 합한 '불안-우울-충동성 표준종합점수합'이 유의미하게 놓았다. 또한 여성이 남성에 비해 특성불안 점수, BIS-11 총점수, 그 하위 3개요인 중 즉흥성(제 2 요인), 운동성(제 3 요인), Beck의 우울증 척도 점수 그리고 이들을 합한 '불안-우울-충동성 표준화 점수의 합'이 유의미하게 높았다. 또 성별 및 흡연여부의 상호작용효과가 있는 변수로는 'Barrat 충동척도 임시 번안판' 총점수, 그 하위 3개 요인 중 즉흥성(제 2 요인), 운동성(제 3 요인), Beck의 우울증 척도 점수 그리고 이들을 합한 '불안-우울-충동성 표준화 점수의 합'이 있었다. 이러한 상호작용 효과를 검증하기 위하여 남성 흡연-비흡연군, 여성 흡연-비흡연군을 비교한 결과 남성의 경우 흡연군과 비흡연군 사이에 이들 모든 척도에서 통계적으로 유의미한 차이가 없었으나, 여성의 경우 흡연군이 비흡연군에 비해 이들 모든 영역에서 유의미하게 높은 점수를 보였다. 결 론 : 이상의 연구결과는 그것이 원인이지 결과인지는 알 수 없으나 흡연자가 대체로 우울, 불안, 충동성 등의 심리적 영역에서 문제가 있으며 특히 여성 흡연자의 경우 그 정도가 심해 흡연의 예방 및 치료에 있어 단순히 신체적 문제만을 부각시킬 것이 아니라 이러한 심리적 요인을 고려해야 함을 시사한다 하겠다. Objective : The study aims to determine whether smokers are more likely to have depression, anxiety and impulsiveness than nonsmokers. In addition, the difference between male and female smokers in terms of psychiatric symptoms are also to be looked at, particularly considered that there is still social stigma against female smokers in Korea. Ultimately, conclusions of the report can decide whether the psychiatric factors should be regarded important in treating smokers and prevention of smoking. Methods : The study is composed of two parts, a preliminary study to check confidence level of BIS-11 and the main study to examine relations between smoking and mental health. For the preliminary study, BIS-11 was translated into Korean to check its confidence level by interviewing 187 people, among whom 30 respondents had gone through an examination and a reexamination with one-week interval. Respondents of the main study were total 550 college students in Cheonan area. The questionaires were categorized into five parts ; 1) sociodemographic variants 2) temporary Korean version of Barrat Impulsiveness Scale(Version 11 : BIS-11) 3) Korean version of Beck Depression Inventory 4) trait anxiety scale from Korean verison of State-Trait Anxiety Inventory. SPSS Win9.0 has been run to analyze the outcome mainly using Two-Way ANOVA and independent T-test. Results : Difference between genders/smokers and nonmokers : The overall score of BIS-11, one of its three subcategories : impromptuness, Beck Depression, and the combined score for multi scales were significantly higher among smokers. Female smokers showed significantly higher scores than male smokers in trait anxiety, overall BIS-11, and two of its three subcategories(indiscretion and motor), Beck Depression and the combined score for multi scales. Overall BIS-11, two of its three subcategories(indiscretion and motor), Beck Depression and the combined score for multi scales were meaningful variants in comparison between male smokers/nonsmokers. While there was no significant difference between smokers and nonsmokers among men, significant difference was identified among women who showed higher scores across all variants. Conclusion : Although it is not sure whether it is the result or the cause of smoking it is confirmed that smokers have problems in psychiatric areas such as depression, anxiety, and inpromptuness, particularly among female smokers to greater degree. Therefore, it strongly implies that psychiatric aspects should be considered in preventing and treating severe smoking problems of female smokers along with physical ill effects.
