This study is carried out to examine the effect of applying Feldenkrais method, elastic band training and combined training on trunk muscle. The subjects of this study were 32 modern dance majors and they were divided into four groups which consists of 8 peoples each, Feldenkrais method group(modern dance + Feldenkrais method), elastic band training group(modern dance + elastic band training), combined training group(modern dance + Feldenkrais method + elastic band training), and control group(modern dance). Measurement variables which are trunk muscle were measured before training, and after 4 and 8 weeks training and the results are as follow: In the left muscle strength change at Centaur 0°, Feldenkrais method group, elastic band training group and combined training group showed significant increase after 8 weeks training compared to before training. In the right muscle strength change, Feldenkrais method group and combined training group had significant increase after 8 weeks training. In the left muscle strength change at Centaur 45°, Feldenkrais method group and combined training group showed significant increase after 8 weeks training compared to before training and after 4 weeks training. Also elastic band training group showed significant increase after 8 weeks training compared to before training. In the right muscle strength change, Feldenkrais method group and elastic band training group significantly increased after 8 weeks training compared to before training. In the left muscle strength change at Centaur 90°, Feldenkrais method group and combined training group showed significant increase after 4 and 8 weeks training compared to before training. In the right muscle strength change, Feldenkrais method group showed significant increase after 4 and 8 weeks training compared to before training, and elastic band training group significantly increased after 8weeks training compared to before training. In the left muscle strength change at Centaur 135°, there was no significant changes. In the right muscle strength change, elastic band training group and combined training group showed significant increase after 8 weeks training compared to before training. In the left muscle strength change at Centaur 180°, combined training group showed significant increase after 4 and 8 weeks training compared to before training. In the right muscle strength change, combined training group showed significant increase after 4 and 8 weeks training compared to before training. From above results, applying 8 weeks regular program of Feldenkrais method, elastic band training and combined training to modern dance majors showed positive changes on improvement of trunk muscle strength and physical strength. Also this study implemented to verify the effects of trunk muscle strength and body balance through supplementary training program, and showed the effects in the training group and control group after 8 weeks trunk muscle strengthening program. Feldenkrais method, elastic band training and combined training are very effective to improve trunk muscle strength of modern dance majors so that continuous implementation and application of these effective training program shall be provided for strengthening trunk muscle.

권오상,송기준,박상훈,송진원,김재선,김종헌,변관수,이창홍,연종은,백락주,박영태 대한간학회 2000 Clinical and Molecular Hepatology(대한간학회지) Vol.6 No.3

$quot;목적: 한국에서 과거 A형 간염은 낙후된 개인위생 및 자연환경으로 유소아기에 불현성 감염으로 앓고 지나가게 되어 청소년 및 성인에서 HAV에 대한 항체 보유율이 매우 높고 성인에서의 급성 A형 간염은 매우 드물게 보고되었다. 그러나 고도의 경제성장과 더불어 식생활, 위생상태의 개선, 상하수도의 보급 등으로 유소아기의 A형 간염 이환율이 현격히 감소하면서 청소년 및 성인에서 HAV 항체가 없는 인구집단 즉 HAV에 감염되면 현증 간염이 발생할 수 있는 인구 집단이 증가되어 최근 수 년 사이에 현증 A형 간염이 폭발적으로 증가하게 되었다. 이에 저자는 HAV의 유전자형을 알아보고 이미 보고된 각국의 HAV와 연관성을 알아보고자 본 연구를 시행하였다. 대상과 방법: 1994년부터 1998년까지 한국에서 산발적으로 발생한 18예의 A형 간염 환자의 혈청에서 HAV RNA를 추출, 역전사-중화효소 연쇄반응법(RT-PCR)으로 증폭하여 직접 염기서열의 분석을 통해 국내 HAV 사이에 염기서열, 아미노산의 차이 등을 알아보고 세계 각국에서 보고되었던 HAV 분리주들과 비교하였다. 결과: HAV 게놈의 특정부위인 VP1/2A 연결부위 168 bp 길이에서 시행한 염기서열 분석 결과 한국에서 분리된 18예의 HA이러스는 최근 해외에서 유입된 바이러스일 가능성은 적으며 따라서 장기간 국내에서 토착화된 바이러스일 것으로 생각된다. $quot;Background/Aims: Studies of genotypes and changes in nucleotide and amino acid sequences of hepatitis A virus (HAV) may provide valuable information on the epidemiological aspects of a particular region. In Korea the prevalence of anti-HAV in the 1 - 20 year age group declined from 60% in 1980 to 9% in 1995. As a result this age group has a high risk of HAV infection. Actually over 1,500 cases of clinically overt hepatitis A occurred in 1998 while few cases of clinical hepatitis A had been reported until the early 1990s. The aims of this study are to determine the genotypes of HAV which have been circulating in Korea and to define the phylogenetic relationships of geographically defined isolates. Method: From 1994 - 1998 a total of 18 serum specimens was obtained from patients in Korea with sporadic form acute hepatitis A. The HAV nucleic acid from serum specimens was subjected to genomic sequence analysis following viral RNA extraction, reverse transcription and amplification of the cDNA by PCR. DNA sequencing was performed in both directions of each PCR product. Results: All isolates clustered within the subgenotype IA irrespective of the geographic locations and timing of the clinical hepatitis. Among 18 Korean isolates, 9 isolates had 2 amino acid sequence changes and 2 isolates had 1 amino acid sequence change. These changes in the amino acid sequences are unique and have never been reported in HAV subgenotype IA. Conclusions: All isolated HAV had genotype (IA). Eleven of 18 isolates had unique changes in amino acid sequences. These data indicate that the endemic HAV has been circulating in Korea over a long period of time.

통증사진에 대한 반복적 통증평가가 의대생의 인지적 공감과 정서적 공감에 미치는 영향

이상권(Sang-Kwon Lee),천경주(Kyung-Ju chun),장철훈(Chulhun L. Chang),김성수(Sung-Soo Kim) 한국콘텐츠학회 2017 한국콘텐츠학회논문지 Vol.17 No.1

본 연구의 목적은 의대생들의 공감능력 수준에 따른 타인의 통증인지 수준 평가와 공감능력의 변화를 파악하여 짧은 시간 내에 공감능력이 낮은 의대생들의 공감능력을 높일 수 있도록 하는 공감교육 컴퓨터 프로그램 개발에 있다. 총 145명 대상자들의 공감능력을 고집단과 저집단으로 나누었다. 또한, 타인의 통증인지 수준 평가를 측정하기 위해 개발한 컴퓨터 프로그램인 ‘Pain Assessment Computer Program(PACP)’을 사용하였다. PACP 수행 후 공감 고집단은 인지적 공감능력만 유의미하게 증가한 반면, 공감 저집단은 인지적 공감능력과 정서적 공감능력 모두 증가하였다. PACP 수행과정에서 두 집단 모두 인지적 공감능력이 공통적으로 증가하였는데 이는 대상자들이 인지적 요소를 우선적으로 사용함으로써 인지적 공감이 상승된 것으로 보이며, ‘인지적 노력’에 따른 인지적 공감능력의 향상에 긍정적인 영향을 준 것으로 판단된다. 이처럼 PACP는 짧은 시간 내에 공감능력이 낮은 의대생들의 공감능력을 향상시키는 보조 수단으로서 활용할 수 있을 것이다. To develop a more efficient computer-based empathy program that enables medical students to increase their empathy ;evels, and to test its applicability to medical students. We developed PACP (the Pain Assessment Computer Program) for measurement of medical students’ levels of recognition of another’s pain. An empathy questionnaire was administered to 145 medical students before and after the PACP. In the high empathy group, the scores for cognitive empathy increased significantly after completion of the PACP, while affective empathy scores showed no significant change. In contrast, in the low empathy group, both cognitive and affective empathy scores increased significantly after the PACP. The PACP effectively increased cognitive empathy for the high empathy group, and increased both cognitive and affective empathy, particularly for the low empathy group. Given the fact that existing empathy education programs are time-consuming and costly, and the demand for more efficient empathy education is high, the PACP as a useful tool can be applicable to medical students, particularly those with low empathy in order to enhance their empathic abilities within a short period of time.

장기간 숙성에 따른 죽초 및 목초액의 이화학적 변화

구창섭,문성필,박상범,권수덕 한국목재공학회 2002 목재공학 Vol.30 No.4

졸참나무, 맹종죽 및 소나무로부터 제조한 미정제 죽초 및 목초액을 약 1년 간 저장하고, 이들의 이화학적 변화를 주기적으로 분석하였다. pH, 유기산·용해타르 함량 및 비중은 전 숙성기간 중 큰 변화가 관찰되지 않았다. 그러나 색차의 경우 7∼10개월 사이에서 현저한 변화를 나타내었다. 또한 이 기간동안에 이들 죽초 및 목초액의 색깔은 연한 노랑 띤 오렌지색에서 자주색과 오렌지색으로 크게 변화하였다. 죽초 및 목초액 중 유기산 및 중성 성분(dihydro-2(3H)-furanone, furfural, furfuryl alcohol, 2-hydroxy-1-methyl-1-cyclopenten-3-one, 1-hydroxy-2-propanone, methanol)들의 함량은 3개월 간격으로 주기적인 증감을 나타내었다. 특히 유기산류와 중성 성분들의 관계는 0.92 정도의 높은 상관관계를 나타내었다. 페놀류의 함량은 비록 유사한 주기적인 증감이 관찰되었으나, 그 함량의 경우 숙성 전 기간에 걸쳐 감소하였다. Three different kinds of the crude vinegars obtained from oak(Quercus serrata), bamboo(Phyllostachys pubescens) and pine(Pinus densiflora) species were stored for approximately one year and periodically analyzed to monitor their physicochemical changes. Small changes in physical properties, such as the pH, specific gravity and amount of organic acids as well as water-soluble tar were observed in the entire course of aging period. However, the color difference of the vinegars showed a remarkable change between 7 and 10 months. In addition, these vinegars' colors changed from light yellowish orange to much deeper purple and orange during this period. The amount of organic acids and neutral compounds(dihydro-2(3H)-furanone, furfural, furfuryl alcohol, 2-hydroxy-1-methyl-1-cyclopenten-3-one, 1-hydroxy-2-propanone and methanol) in the vinegars increased or decreased periodically every three months. A good linear relationship (correlation coefficient of ca. 0.92) was obtained between the amount of organic acids and the amount of neutral compounds in such changes. However, although the amount of phenols increased or decreased periodically, its amount was decreased over the entire aging period.

출산에 따른 그레이브스병의 재발 및 관련이자

Background: Pregnancy affects the course of Graves' Disease (GD), and patients who initially maintain euthyroid function into their middle trimester with minimum doses of antithyroid drugs become exacerbated after delivery. Even patients who are completely cured, requiring no treatment during pregnancy, can relapse after delivery. In this study, we examined the postpartum changes in the thyroid functions of patients with GD, and attempted to determine the factors contributing to these changes. Methods: The study subjects were recruited from pregnant women visiting our outpatient clinic for routine prenatal evaluations. 45 women previously diagnosed with GD, who had been treated and cured with hyperthyroidism, and were no longer taking any thyroid medications, were evaluated for 1 year post delivery. Results: Among 45 patients, 20 (44.4%) developed thyroid disorders following delivery. Postpartum thyroiditis (PPT) developed in 8 patients (17.8%), and GD developed in 12 (26.0%). The onset of the PPT disease 3.1 ± 1.4 months following delivery, which was significantly earlier than the 6.7 ± 2.7 months required for the post delivery onset of GD (p=0.003). The TBII values, measured during the thyrotoxic state in each womaen, were negative in women with PPT and positive in 71.4% of women with GD (p=0.030). The duration of treatment for hyperthyroidism prior or pregnancy, the number of recurrences, and the time interval without treatment, were not associated with the development of postpartum thyroid disorders. Whereas, the mean number of past pregnancies for women who developed PPT was 3.9 ± 2.1, and was significantly higher than the 2.2 ± 1.7 for women developing no thyroid dysfunctions (p=0.044). In 13 women their initial onset of GD occurred within one year postpartum, 7 (53.8%) having had a recurrence, which was significantly higher than in women whose disease onset occurred unrelated to delivery (5 of 32 women: 15.6%). Conclusion: Women with GD developed postpartum thyroid dysfunctions in 44.4% of cases. Women whose initial disease onset occurred within one year postpartum had higher recurrences of GD, and women who developed PPT had a history of higher gravidity compared to the euthyroid women postpartum. Therefore, if women with GD develop postpartum thyroid dysfunctions, the diagnosis should be made, and a treatment modality planned, following careful considerations of the patients' past obstetric history, changes in clinical manifestations and the TBII values

Background/Aims: Westernization in many Asian countries have changed lifestyles and diets, so once rare diseases have now become prevalent. The aim of this study is to investigate the changing pattern of digestive and liver disease in Korea, from 1990 to 2006. Methods: We extracted data specific gastrointestina (GI) disease based on the International Classification of Diseases code from the in-patients records at the Kangnam St. Mary`s Hospital in 1990, 1996 and 2006. This hospital is a tertiary-care hospital in Seoul, Korea, which has a capacity of 800 beds. Results: The admission rate for GI disease increased between 1990 and 2006. Overall in-patients were 1,623 persons in 1990, 2,368 persons in 1996 and 4,166 persons in 2006. The mean age of in-patients increased as time went by. A stomach cancer was the most common diagnosis during all periods, but its prevalence has decreased. Colon cancer ranked the 7th in 1990, but markedly increased and now ranks the second. The third was a hepatocellular carcinoma. The bile duct and gallbladder cancer, pancreas and esophageal cancer ranking followed with little interval change. In cases of cancer patients, a regular admission dramatically increased for chemotherapy. The number of patients admitted with pre-malignant neoplasm of stomach and colon increased remarkably with the development of endoscopy. The liver transplant, inflammatory bowel discase, and reflux esophagitis emerged form mid-1990s with greater frequencies, yet much below the levels found in the West. The admission rate for peptic ulcer, especially ulcer bleeding remained relatively stable, despite a decreased rate for ulcer perforation. Liver cirrhosis, hepatitis, cholelithiasis with cholecystitis-cholangitis, appendicitis, hemorrhoid and gastritis all decreased. Conclusions: The stomach cancer is the leading cause of admission, despite a recent decline. Colon cancer showed a marked rise. The liver transplant, inflammatory bowel disease and reflux esophagitis were new diagnosis with an increased tendency.

천봉희,권성민,장진열,조성남,조 웅,권도훈 대한생물치료정신의학회 2002 생물치료정신의학 Vol.8 No.2

저자들은 양국성 장애 조중삽화 및 혼재성 삽화의 단독 치료제로서 새로운 항경련제인 topiramate의 항조증 효과와 안정성을 평가하기 위하여 본 연구를 하였다. 양극성 장애 조증 삽화와 혼재성 삽화로 진단이되어 입원을 한 환자 14명(남자 6명, 여자 8명)을 대상으로 topiramate를 단독으로 6주간 투여하였다. Young's Manic Rating Scale(YMRS), Brief Psychotic Rating Scale(BPRS)로 환자들의 증상정도를 평가하였으며, 추가해서 체중변화도 측정하였다. 연구결과, YMRS, BPRS 평균점수 및 체중은 topiramate 치료 전에 비해 6주 치료 후에 유의하게 감소되었다. 또, YMRS 점수가 20미만일 때 조증상태가 안정된 것으로 본다면, 본 연구에서 치료 6주 후 YMRS 점수가 20미만인 환자는 14명 중 7명으로 topiramate의 치료 반응률은 50%라 할 수 있다. 가장 흔한 부작용은 위장관 증상으로서 식욕감퇴, 구역, 설사 등이었으며, 이는 6주 연구 후에 topiramate 치료를 중단하게 하는 원인이었다. 진전이나 이상감각은 대체로 topiramate를 투여한 후 1∼2주 내에 나타났다가 1∼2주 지속된 후 사라졌다. 향후 연구에서는 본 연구의 제한점을 보완하는 대조군 연구가 필요하며, 부작용을 줄이기 위한 보다 적절한 topiramate의 증량방법도 고안되어야만 할 것이다. Objectives : Topiramate is a newly developed anticonvulsant agent with possible mood-stabilizing properties. The purpose of this study is to explore the antimanic efficacy and the tolerability of topiramate as monotherapy in bipolarⅠdisorder, most recent episode manic or mixed. Method : In this study, fourteen hospitalozed patients who met the DSM-Ⅳ criteria for bipolarⅠdisorder, most recent episode manic or mixed were given topiramate monotherapy for up to 6 weeks. The response to topiramate was assessed with Young's Manic Rating Scale(YMRS) and Brief Psychotic Rating Scale(BPRS). Body weight changes were also measured. The Ratings were completed at baseline nad then on 1,2,3,4, and 6 weeks. Results : The mean Young's Manic Rating Scale(YMRS) score improved from 38.36(25-42) at baseline to 22.29(12-37) at the end of the study. The Brief Psychotic Rating Scale(BPRS) score improved from baseline mean of 44.64(35-60) to a last observation of 28.92(13-43). The mean body weight decreased from 62.43kg(47-81kg) to 58.64kg(45-81kg). At the end of study, seven patients scored less than 20 on the YMRS score, three of them were less than 13, Adverse events included anorexia(N=9), nausea(N=6), diarrhea(N=4), paresthesia(N=4), tremor(N=2), and rash(N=1). Conclusion : In this study, the response rate to topiramate was 50% as a treatment agent for bipolarⅠdisorder, most recent episode manic or mixed and topiramate might be associated with weight loss. But the adverse effects such as gastrointestinal sympotoms decreased the compliance of topiramate. Inthe future, double-blind controlled studies are needed to further investigate the antimanic efficacy and tolerability of topiramate.

최근 30년간 스포로트리쿰증 임상 병형의 추세에 대한 관찰

임채성,권경술,장호선,정태안,오창근 대한의진균학회 1997 대한의진균학회지 Vol.2 No.1

Background: The clinical types of sporotrichosis are generally classified into four group: lymphocutaneous, fixed cutaneous, and cutaneous disseminated, and hematogenous. Of these, the lymphocutaneous variety is the most frequently encountered pattern, constituting 80% of sporotrichosis patients and the fixed cutaneous sporotrichosis is the next. Potassium iodide (KI) was the most commonly used drug for the treatment of sporotrichosis. Many studies about these clinical findings of sporotrichosis have been reported, but comparative study on the changes in clinical findings has not been reported. Objective: The purpose of this study is to clarify the changes of the clinical findings in sporotrichosis in Korea. Methods: A total of 58 patients with sporotrichosis who had visited the Department of Dermatology, Pusan National University were divided into 2 groups according to the period and then the clinical findings of sporotrichosis were compared. Results: The results of study are summarized as follows: 1. During this period, there were 58 cases of sporotrichosis. In the past period (1967~1979) there were 35 cases of sporotrichosis, and there were 23 cases in the recent period (1980~1997) 2. In the past period, most cases (71.4%) were lymphocutaneous type, however in the recent period, most cases (69.2%) were fixed cutaneous type. 3. The most commonly affected site was right upper extremity in the past period, but face fright upper extremity were the most commonly affected sites in the recent period. 4. In the past period, 2nd and 3rd decades were prevalent age group, but 5th to 7th decades were prevalent age group in the recent period. 5. In the treatment of sporotrichosis, potassium iodide (KI) was the choice of treatment in the past period, however itraconazole is gradually used in the recent period. Conclusion: According to this study, many changes in clinical findings of sporotrichosis were noted, especially in the clinical type. We found that clnical type of sporotrichosis changed from lymphocutaneous type to the fixed cutaneous type with time. And we suggest that further observation would be necessary to define the meaning of these changes.

The purpose of this study proposed an effective method improving obesity of adolescents who attend a combined exercise program during 12 weeks, by obesity stress, changes in blood levels of Appetite control hormone(ghrelin, leptin). The subjects of study were a total of 18 persons each 9 people, allocating combined exercise group (CG), control group(C) that divided by using the simple method conducted obese boys who had more than 25 percent body fat from pre-test. Combined exercise took four days a week, 45 minutes per a day and continued total 12 weeks. Measurement and analysis of all participants were measured after 12 weeks of pre-and post-test. For comparison of each group repeated measurements were performed among groups (repeated measure analysis of variance). The level of statistical significance in all analysis was set at α =. .05. Then that produced through the research process and how conclusions are as follows:1)changes of Ghrelin :CG group showed significant difference(p<.05) in group that ghrelin was decreased from 772.19pg/㎖ at 0 day to 429.77pg/㎖ at 12th week. 2)changes of Leptin : In CG group, the amount of leptin was increased from 12.38ng/㎖ at 0 day to 17.83ng/㎖ at 12th week(p<0.05). 3) Change of obesity stress: In CG group obesity stress was reduced from 109.33 at 0 day to 52.17 at 12th week, respectively. In CG group, obesity stress were significant difference (p<.05). In summary of above results, it showed that ghrelin and leptin hormone concentrations in blood were significantly changed. Therefore, we confirmed that continuous combined combination of exercise were positively effects for obese adolescents as a tool associated with a interventions of obesity.
