배경 및 목적: 본 연구는 전자구개도를 사용하여 한국어의 치경마찰음인 /ㅅ/와 /ㅆ/를 조음운동적 측면에서 비교 분석해보고, 치경마찰음 조음 시 나타나는 혀-구개 접촉에 관한 정보를 제공하기 위한 목적으로 시행되었다. 방법: 한국어가 모국어이며 발음에 문제가 없는 정상 성인 5명이 전자구개도를 착용하여 치경마찰음을 분절음 차원에서뿐 아니라 단어 내 위치 및 모음문맥을 달리하여 녹음한 후 팰라토그램을 분석하였다. 결과: 그 결과, /ㅅ/와 /ㅆ/는 협착의 너비와 혀-구개 최대접촉구간에서 유의한 차이를 보였다. /ㅆ/에서 협착의 너비가 더 좁고 전체 혀-구개 접촉구간은 더 넓게 나타났다. 단어 내 위치에 따른 차이는 유의하지 않았지만, 고모음인 /ㅣ/ 문맥에서는 저모음인 /ㅏ/에 비해 협착의 위치가 후방화되었으며, 지속시간도 가장 긴 것으로 나타났다. 또한 혀-구개 접촉 구간도 가장 넓게 나타났다. 논의 및 결론: 본 연구는 전자구개도를 사용하여 한국어 치경마찰음의 혀와 구개 접촉에 관한 정보를 제공했다는 점에서 그 의의를 갖는다. 또한 본 연구의 결과는 한국형 전자구개도의 개발의 기초자료로써 그 의미가 있다. Objectives: The present study is aimed an electropalatographic investigation of Korean fricatives /s/ and /s*/. All data from this study is based on the production of 5- adult speakers who speak Korean as their first language. Methods: Electropalatography (EPG) is an instrumental technique for showing tongue and palate contact during speech. The participants recorded /s/ and /s*/ in CV (/si/, /sɑ/, /su/, /s*i/, /s*ɑ/, /s*u/) and VCV (/ɑsi/, /ɑsɑ/, /ɑsu/, /ɑs*i/, /ɑs*ɑ/, /ɑs*u/) context using EPG and then, four variables were analyzed: row of medial groove (RMG), medial groove width (MGW), medial groove length (MGL), and maximum contact frame (MCF). Results: There was significantly greater medial groove width and maximum contact frame for / s*/ compared to /s/. The difference between /si/ and /sɑ/ was also found in the row of medial groove, medial groove width and maximum contact frame. /si/ was produced further back, and had a longer medial groove length. Also, it showed more total tongue-palate contact than /sa/. Conclusion: A various range of palatal contact patterns were found between typical adults for perceptually normal /s/ and /s*/. The results provided the information about tongue–palate pattern of Korean fricatives /s/ and /s*/. These findings would be utilized to build the basic data and useful information for Korean EPG system.

Ji?Wook Jung,Sa?Rang Oh,Eun?Mi Ahn,Eun?Ju Yang,Su?Jin Kim 대한의생명과학회 2013 Biomedical Science Letters Vol.19 No.3

Ulcerative colitis (UC) is an inflammatory bowel disease, which is a chronic gastrointestinal disorder. Adenophorae Radix (AR) has been used as a traditional medicine for various diseases including strengthening cardiac function, allaying a fever, and easing pain and cough. However, the regulatory effects of AR in intestinal inflammation are not yet understood. This study attempted to determine the effect of AR in dextran sulfate sodium (DSS) ? induced colitis in mice. The colitis mice were induced by drinking water containing 5% DSS for 7 days. The results showed that mice treated with DSS showed remarkable clinical signs, including weight loss, and reduced colon length. Administration of AR attenuated weight loss, colon shortening and inhibited the levels of interleukin (IL) ? 6 in DSS ? treated colon tissues. These results provide experimental evidence that AR might be a useful therapeutic medicine for patients with UC.

Background: With reports on the relation between smoking and depression appearing since 1980, it has become clear that depression is one of the psychodynamics of smoking, though there has been little or no progress made in the study of whether or not there is indeed a relation between depression and nicotine dependence. Purpose: The purpose of the study was to investigate the effects of depression on the amount and period of smoking and nicotine dependence among university man student smokers. Method: In periodical examination between 14 and 21, May, 2003, using 170 university male. The CES-D(Center for Epidemiologic Studies Depression) Scale and the FTQ(Fagerstrom Tolerance Qustionnaire) were utilized to measure the level of depression and nicotine dependency. The amount of smoking was calculated based on the number of cigarette used. Result: Results indicated that depression had something to do with amount of smoking. Nicotine dependence also was related to depression but total value was relatively low. finally the period of smoking had nothing to do with depression. Conclusion: The results of this study revealed that the amount of smoking of university man student smokers was very high. Both the amount of smoking and nicotine dependence were affected by levels of depression. Accordingly psychiatric nursing access such as emotional support is needed to manage depression and decrease smoking.

이수진,박지영,오상훈,윤영호 대한건축학회 2003 대한건축학회 학술발표대회 논문집 - 계획계/구조계 Vol.23 No.1(구조계)

This study was to investigate the structural behavior of braced-frame systems with slit damper. For this study, push-over analysis was carried out to investigate the difference of structural behavior between the braced frame system without slit-plate dampers and the braced frame system with slit-plate dampers. The braced-frame systems with slit plate dampers were more effective than the braced-systems without slit-plate dampers: (1) The plastic hinges which were happened at damper were decentralized each story so that the plastic deformation of the main frames were decreased. (2) The ductilities of the former structure were increased.

In this paper, the fabrics for Korean folk clothes(KFC) undergoes repeated laundering under given condition. After this cyclic laundering was applied, the mechanical properties of the specimen were measured using KES-F system in order to evaluated the end-use performance of fabrics for KFC. And also, the crease recovery of fabrics for KFC were measured by shirley crease recovery tester. 78 different kinds of commercial silk fabrics and polyester fabrics for KFC were used for this study. The experimental results were analysed statistically to relate the mechanical properties and the crease recovery of fabrics for KFC. Furthermore, these changes in dimensional stability, mechanical properties and handle of fabrics for KFC were discussed in comparison with those values for silk fabrics and polyester fabrics. The results obtained are as follows. 1. Regardless of materials, remarkable increase are observed in shrinkage of the fabrics for KFC about repeated laundering, but dull increase are observed in shrinkage after 10 cycles of the repeated laundering. On the other hand, slack extend are observed in dimensions after 20 cycles of the repeated laundering. The shrinkage of fabrics for KFC after 10 cycles of the lundering showed that the silk fabrics are 1.74±0.33% (warp direction) and 1.35±0.23% (weft direction) and the polyester fabrics are 1.45±0.22% (warp direction) and 1.25±0.23% (weft direction). 2. Except for tensile property, these changes in mechanical properties of fabrics for KFC by laundering have ±16 range of bending, shearing, compression, surface, thickness & weight as compared with before laundering. Particularly, the LT and RT about 1∼3 cycles of the repeated laundering showed remarkable decrease. And SMD, WC, T & W of fabrics for KFC by the laundering were more increased than one for original fabrics. But B, 2HB, G, 2HG, 2HG5 were decreased more than one for original fabrics. 3. "Stiffness", "Anti-drape", "Crispness" and "Scroop" hand values decrease and"Fullness & softness", "Flexibility & softness" hand values increase with repeated laundering. 4. Remarkable decrease are observed in crease recoveries about 1∼5 cycles of the repeated lundering, but slack decrease are observed in crease recoveries after 5 cycles of repeated laundering. The crease recovery of fabrics for KFC have negative(-) correlation with LT, RT, G, RC and MMD, This fact implies that the smaller these values, the larger the crease recovery. The crease recovery of fabrics for KFC has a high degree of correlation with the mechanical properties such as shearing, compression, surface property. And also, the crease recovery are expected by measuring the mechanical properties such as G, 2HG, 2HG5, RC, WC, LC, MIU, MMD and SMD, according to the obtained regression equation.

이학수,이경훈,오지훈 충북대학교 연초연구소 2009 煙草硏究 Vol.22 No.-

본 연구는 담배식물의 바이오에타놀 생산원료서의 가능성을 타진하기 위하여 온실에서 pot재배를 통하여 이식 후 25일부터 80일까지 5일 간격으로 잎과 줄기의 holocellulose와 lignin함량 변화를 조사해 보았다. 생육이 진행됨에 따라 건물 g당 holocellulose와 lignin의 함량도 증가하여 성숙 및노화기로 갈수록 높았다. 건물 g당 holocellulose함량은 잎보다 줄기가 높았고, 줄기의 lignin함량은 최대생장기에 급격히 증가했다. 담배 1주당 총 함량은 이식 후 70일에 최대였는데, holocellulose함량은 건물중의 60%이었고 lignin을 합할 경우에는 67%가 되었다. Changes in holocellulose and lignin contents of tobacco p1ants(var. NC 82) were determined from 25 days after transplanting in a pot to senescence stage at 5 days interval in green house. The amount of holocellulose and lignin per g of dry matters were increased from growing to senescence stage. The hollocellulose content of dry stalk was higher than of leaf, and lignin content of stalk was increased rapidly during the maximal growing stage of tobacco plant. The total amounts of holocellulose and lignin per a tobacco plant were reached maximum at the around 70 days after transplanting. At that time, the ratio of holocellulose only and holocellulose with lignin to dry matter was about 60% and 67%, respectively.

연구목적 : 외환위기 이후에 급증한 노숙자 문제는 경제적인 상황의 호전에도 불구하고 만성화하는 경향을 보이고 있다. 쉼터의 노숙자를 대상으로 정신질환의 유병율과 삶의 질에 대한 조사를 시행하였다. 방 법 : 2000년 3월에 서울의 대표적인 쉼터에 거주하는 노숙자220명을 대상으로 인구학적 자료에 대한 설문조사를 한 뒤 Structured Clinical for DSM-Ⅳ(SCID-I)을 이용하여 AxisⅠ의 주요 정신질환을 진단하였다. 또 SmithKline Beecham Quality of Life Scale(SBQOL)를 사용하여 삶의 질정도를 평가하였다. 결 과 : DSM-Ⅳ AxisⅠ의 정신질환 중 기분장애, 정신병적 장애, 물질 사용 장애에 대한 진단 평가 결과 상기정신질환의 전체 평생 유병율은 73.6%, 현재 유병율은 59.1%이었다. 알코올 의존과 남용의 평생 유병율은 59.5%로 가장 높았고, 기분장애와 장애가 각각 39.5%, 3.6%이었다. 삶의 질은 노숙의 기간이나 실직 기간과 유의한 관계가 없었고, 자신이 지각한 건강상태, 자살과거력, 우울장애 유무와 통계적으로 유의하게 상관관계가 있었다(p<0.01). 결 론 : 노숙자에서 정신질환 중 알코올 장애의 유병율이 가장 높았으며, 우울장애가 있는 경우에 삶의 질이 저하되는 것으로 나타났다. Objectives : Homeless people surged after financial crisis tend to be chronic despite late economic recovery. So we tried to estimate prevalence of mental illness and quality of life of the homeless population living in shelter. Method : The study subjects were 220 homeless peoples who stayed at a shelter in Seoul around March 2000. Questionnaires on sociodemographic data were administered to the subjects, and then diagnoses of major DSM-Ⅳ Axis I mental disorders were made using Structured Clinical Interview for DSM-Ⅳ Axis I Disorders(SCID). And quality of life(QOL) was evaluated by SmithKline Beecham Quality of Life(SBQOL). Results : The lifetime prevalence of major DSM-Ⅳ mental disorders(mood disorders, psychotic disorder, and substance use disorder) of 220 homeless people was 73.6%, and current prevalence was 59.1%. The lifetime prevalence of alcohol dependence and abuse was highest, 59.5% and those of mood disorder and psychotic disorder were 39.5%, 3.6% respectively. Quality of life was not significantly correlated with duration of homelessness and unemploy-ment but marital status, self perceive health status, suicidal attempt history were significant factors. The quality of life in the people with mood disorders were estimated to be lower than those with any other diseases(p<0.01). Conclusion : Alcoholism was the most prevalent mental disorder in homeless people and mood disorder was negatively related to the quality of life scale.

국내 다기관에서 조사한 지역사회획득 메티실린내성 황색포도알균의 빈도와 임상적 특성

송진수,최평균,송경호,조재현,김성한,방지환,이창섭,박경화,박경운,신수,최희정,김의석,김동민,이미숙,박완범,김남중,오명돈,김의종,김홍빈,최강원 대한감염학회 2006 감염과 화학요법 Vol.38 No.6

목적 : 최근 전세계적으로 지역사회획득 메티실린내성 황색포도알균(community-associated methicillin-resistant Staphylococcus aureus, CA-MRSA)의 보고가 증가하고 있다. 하지만, 우리나라에서는 CA-MRSA 감염증에 대한 증례보고만 있을 뿐 아직까지 체계적인 연구결과가 없는 실정이다. 저자들은 국내에서 CA-MRSA의 빈도, 감염증의 임상적 양상, 분리된 균주의 항균제내성 양상을 조사하였다. 재료 및 방법 : 2005년 1월부터 2005년 6월까지 7개 병원에서 MRSA가 분리된 환자의 명단을 파악한 후 의무기록지와 건강보험심사평가원의 자료를 검토하였다. 외래나 응급실에서 혹은 입원 후 72시간 이내에 균주가 분리되고 MRSA 획득과 관련된 위험인자가 없는 경우 CA-MRSA로 정의하였으며, 분리된 균주의 임상적 의미에 따라 원인병원체(pathogen), 집락화(colonizer), 미결정(undetermined)으로 분류하였다. Penicillin과 oxacillin을 제외하고 3개 이상의 다른 계열 항균제에 내성이면 다제내성으로 정의하였다. 결과 : 연구기간동안 총 3,251주의 황색포도알균이 분리되었으며, 이 중 MRSA는 1,900주(58.4%)였다. MRSA 가운데 CA-MRSA는 114주(6.0%) 였으며, 이들이 분리된 부위는 귀(62주), 비뇨기계(14주), 피부 및 연부조직(11주), 호흡기계(10주), 혈액(3주) 등이었다. CA-MRSA 균주 가운데 집락균은 22주, 원인병원체는 22주였으며, 나머지 균주에 대해서는 그 임상적 의미를 결정할 수 없었다. 항균제 감수성 검사를 시행한 73균주 중 47주(64.4%)는 다제내성이었다. CA-MRSA 감염증 22예 중 피부 및 연부조직 감염(9예)과 중이염/외이도염(9예)이 가장 흔하였다. 침습적 감염증(invasive infection)은 4명(원발성 균혈증 3예, 감염성 관절염 1예)에서 확인되었지만, CA-MRSA 감염증으로 사망한 환자는 없었다. 결론 : 병원내 감염증에서는 MRSA가 심각한 문제이지만, 아직까지 지역사회 감염증에서 CA-MRSA는 흔하지 않았다. Background : Methicillin-resistant Staphylococcus aureus (MRSA) infection has emerged in patients who do not have the established risk factors. In Korea, little is known about the epidemiology and clinical features of community-associated MRSA (CA-MRSA). Material and Methods : Clinical microbiology laboratory databases of 7 hospitals were reviewed to identify the patients from whom MRSA was isolated during the period of January to July 2005. Only one isolate per patient was enrolled. In order to identify the risk factors of MRSA acquisition, the medical records and the Health Insurance Review Agency databases were reviewed. CA-MRSA was defined as MRSA isolated from patient without established risk factors. We analyzed patient demographics, underlying medical conditions, characteristics of infection, and antimicrobial susceptibility profiles. Results : Of total 3,251 S. aureus isolates, 1900 (58.4%) were MRSAs. Of the MRSA isolates, 114 (6.0%) were CA-MRSA. Of 114 CA-MRSA isolates, 22 (19.3%) were colonizers, 22 (19.3%) were pathogens, and the clinical significance of remaining 70 (61.4%) could not be determined. Median age of the 22 patients with CA-MRSA disease was 47 years. Nine patients had skin and soft tissue infections, 9 ear infections, 3 bacteremia, 1 septic arthritis. Seven patients had underlying medical disease. None died of the CA-MRSA infections. Of the 73 isolates of CA-MRSA, 47 (64.4%) were resistant to more than 3 classes of antibiotics besides β-lactams. Conclusion : Although MRSA is highly prevalent among hospital-associated S. aureus infection, CA-MRSA infections are not common.

이창섭,송진수,최평균,조재현,방지환,박경화,박완범,김홍빈,김남중,윤성수,박선양,김병국,오명돈,최강원 대한감염학회 2006 감염과 화학요법 Vol.38 No.5

혈액질환 가운데 결핵 발생이 증가한다고 알려진 것은 호지킨 림프종을 포함한 림프증식성질환 그리고 모양세포성 백혈병 등이 있다. 또한 동종 골수이식을 받은 환자에서도 결핵은 증가한다고 알려져있다. Kaplan 등은 골수구성 백혈병 환자에서 결핵 발생이 증가한다고 보고하였다. 그러나 골수구성 백혈병 환자에서 결핵의 발생이 증가하는 이유에 대해서는 아직까지 정확하게 밝혀지지 않았다. 저자들이 2년 동안 후향적으로 조사한 180명의 성인 골수구성 백혈병 환자들 가운데 결핵이 발생한 환자는 4명이었고, 발생 부위는 모두 림프절이었다. 결핵은 골수구성 백혈병의 특정 아형에만 국한되어 발생하지 않았지만, 50%에서 FAB 분류에 의한 M4였다. 림프절이 종대된 골수구성 백혈병 환자에서 특히, 결핵의 유병율이 높은 나라에서는 결핵성 림프절염도 감별진단에 포함시켜야 한다. During the neutropenic phase, leukemia patients receiving chemotherapy are prone to bacterial and, fungal infections; occasionally mycobacterial, viral and protozoal organisms may also cause infections. Mycobacterium tuberculosis infection was reported very rarely in these patients. This report describes four patients with M. tuberculosis infection identified from 185 adult patients who were diagnosed myelogenous leukemia between January 2003, and December 2004. There was no patient with M. tuberculosis infection from 44 lymphoid leukemia and 11 acute biphenotypic leukemia patients. Sites of infection were all lymph nodes. Three among four patients were presented with lymphadenopathy at initial diagnosis of leukemia, and the other one presented with lymphadenopathy after induction chemotherapy. There was no patient presented with lymphadenopathy during the neutropenic phase. Tuberculous lymphadenitis was presented in a patient with three acute myelogenous leukemia (FAB class 2 M4, 1 M2) and a chronic myelogenous leukemia, accelerated phase. An acute myelogenous leukemia patient had a leukemic cell and tubercle bacilli in the same lymph node. Tuberculosis should also be included as a differential diagnosis in myelogenous leukemia patient with lymphadenopathy, especially in the countries in which the disease is endemic.
