TDI-induced bronchial asthma is an important occupation-related disease. The prevalence rate of this asthma is 5-15% of people exposed to TDI. The patients of cases complained of chronic cough, sputum and dyspnea after exposure to TDI. Serum IgE and total eosinophil count were within normal range. In case 1, FEV₁was 59.9% of predicted value on initial visit. FEV₁was decreased to 62.9% of baseline and wheezing sound was detected on 15 minutes after inhalation of TDI by bronchial provocation test. Only immediate reaction was observed. FEV₁was improved to normal ragne 10months later after cease of exposure to TDI. In case 2, FEV₁was 74.2% of predicted value on inital visti, and 44.6% on the second visit. After inhalation of bronchodiator. FEV₁was improved 18.1%. FEV₁was decreased to 40.6% and 49.8% of baseline on 15 minutes and 350minutes, respectively, after inhalation of TDI by bronchial provocation test. Dual reaction was observed. In case 3, FEV₁was 48.2% of predicted value on initial visit. FEV₁was decreased to 58.6% and 62.0% of baseline on 20 minutes and 310 minutes, respectively, after inhalation of TDI by bronchial provocation test. Dual reaction was observed. On follow up examination, the patient complained of an intermittent dyspnea and FEV₁was 51.1% of predicated value.

The purpose of this research is to investigate, with reference to majoring-in-dance undergraduates' participating in a dance, the influence upon self-concept. The subjects were 283 undergraduates who are majoring at dance in senior colleges of Seoul and Gyeonggi province as of 2001. As for a self-concept questionnaire, on the basis of the hypothetical model of Shavelson, Hubner and Stanton(1976) the measuring and testing paper used by Kang Sin-wook(1992), Kang Jin-hong(1998) and Jin Seong-yong(1999) was finally used by being modified and supplemented to suit the purpose of this research. The factor-analysis results show 54.5% and its reliability coefficient was .8957∼.8423. For data processing, Correlation Analysis and Multiple Regression Analysis were carried out, and the results are as follows. First, majoring-in-dance undergraduates' degree of participating in a dance did not have an influence on a social self. Second, their degree of participating in a dance had an influence upon a cognitive self. In more detail, the variable of participation terms had a statistically significant influence at p<.001 level, but participation frequency and participation intensity did not exert a significant influence. Third, their degree of participating in a dance had an influence upon a physical self partly. Concretely, the variable of terms of participating in a dance had a statistically significant influence at p<.01 level. However, participation frequency and participation intensity did not have a significant influence.

수면, 기억 그리고 학습의 연관성은 실제 매우 복잡하다. 많은 연구에도 불구하고 명확한 연구결과는 아직 없다. 우리는 이 연구에서 평소와는 달리 시험 전날 수면 변화 양상이 집중력에 어느 정도 영향력을 미치는지 알아보고자 하였고, 이를 이용해 효율적인 수면 관리를 할 수 있는 기초자료로 삼고자 하였다. 동국대 의대 본과 1학년생 중 지원자 30명과 본과 2학년생 10명을 대상으로 평상시 상태와 시험 직후 수면이 부족한 상태에서 각각 K-PES TEST를 실시하여 총 8항목에 걸쳐 암기력, 판단력, 단순반응의 변화정도를 검사하였다. 또 설문조사를 병행하여 결과에 영향을 미칠 수 있는 다른 인자들도 파악하였다. 수면량에 대한 부호 숫자 짝짓기(순간 판단력)을 검사한 결과, 인간의 최대 생리학적 기능은 꼭 수면부족에 의해 좌우되는 것은 아니다. 그러나, 수면감소는 피로를 증가시키고, 동기부여를 감소시키나 단, 새로운 사실을 학습하는 데에는 큰 영향을 끼치지 않는다. 즉, 수면부족으로 장시간 깨어있는 것은 정확성과 반응성을 떨어뜨린다. 흡연에 대한 부호 숫자 짝짓기(순간 판단력)을 검사한 결과, 니코틴의 수면에 대한 상호관계는 알려지지 않았고, 인간의 감정이나 의식, 인식에 영향을 주는 것으로 알고있지만, 장기적은 측면에서 흡연이나 알코올은 인식능력과 무관한 것 같다. 카페인에 대한 숫자 외우기(암기력)검사 결과, 카페인은 spacial selective attention에는 특별한 영향을 주지 않지만 지각과정이나 주의 집중에 큰 효과를 주며, 인간의 의식 수행에 긍정적인 효과를 준다. 즉 카페인은 활력, 혼란, 피로상태를 변화시키고 visual analog scales에서 휴식상태에 가까운 양상을 나타낸다. 또 48시간 동안 수면을 취하지 않은 사람에게 카페인은 집중력과 장시간의 좋은 기분을 유지하게 하였다. 그러나 규칙적, 비규칙적으로 먹는 사람간에는 인지수행력의 차이를 보이지 않으며 상용자에서는 상당한 내성이 보인다. 수면패턴에 대한 숫자 더하기(순간 판단력)검사 결과, 집중력은 수면패턴에 의해서도 영향을 받고, 수면패턴이 바뀌게 되면 순간판단력을 저하시킨다. This study was performed to evaluate relationship of sleep and attention, and to control sleep effectively. We conducted a K-PES test of 40 medical students. K-PES contains eight elements, for example, simple response, selective response, color pairing, OddEven discrimination, number addition, number-symbol matching, memory, right-tapping, left tapping. Through these, we tested changes of memory, judgement, simple response. And we conducted a questionnaire survey to exclude bias. Results are as follows. As a results of number-symbol matching test, we know that sleeplessness is not complete responsible for physiologic function for humans. But, decreased sleep increases fatigue and decreases motivation, but no influence on learning new materials. So, long term sleeplessness decreases precision and responsibility. As a results of number-symbol matching test on smoking, a relationship of nicotine and sleep is not certain. A point of view in long term period, smoking and drinking is not related cognition, even if we know that those influence mood, consciousness and cognition. As a results of memory work test on caffeine, caffeine does not influence spacial selective attention, but mainly does perception, attention and consiousness process. Namely caffeine changes energetic activities, chaos, fatigue states and shows resting state in visual analog scales In sleeplessness for 48 hours, caffeine produced attention and good mood for a long time. But, in case of cognitive process no significance shows in regular or irregular diet. Regular diet shows high resistance. As a results of number addition test on sleep patterns, seep patterns influence attention, changes of sleep patterns decrease a moment judgement.

Objectives : To investigate the applicability of thermography as severity measurement in the patients with osteoarthritis (OA) of the knee. Methods : Data were obtained from 80 patiens with OA of the knee. They were asked to answer two disease-specific questionnaire (Western Ontario and McMaster Universities (WOMAC) OA index, Lequesne's Functional Index (LFI)), one generic instrument (Korean Health Assessment Questionnaire (KHAQ)), VAS in order to assess the severity of disease, quality of life, degree of pain and taken thermography in standardized environment. Results : The thermal difference between ipsilateral side and contralaterla side of lateral aspect of knee was correlated with that of medial aspect of knee, and the thermal difference of anterior thigh was correlated with that of lateral, medial aspect of knee and patella region. Age, duration of disease, duration of morning stiffness, sex, crepitus, and painful side of knee were not correlated with the thermal differences of each region. LFI, WOMAC, WOMAC pain subscale, WOMAC stiffness subscale, WOMAC physical function, KHAQ,, VAS were not correlated with the thermal differences of each region. Conclusion : Further study on the thermography on OA of the knee in population with appropriate severity grade and the standardization of analysis of thermographic data were recommended.

본 연구는 초등학생의 과학에 대한 인지모니터링 기능이 어느 정도인지, 또한 학년별 수준은 어떠한지를 알아보는데 그 목적이 있다. 연구 대상은 대전시에 위치하는 5개 학교에서 2~6학년까지 각 1개반을 표집하여 총 1001명을 대상으로 2~4학년용인 과학 인지모니터링 검사지Ⅰ(TSCMⅠ)와, 4~6학년용인 과학 인지모니터링 검사지Ⅱ(TSCMⅡ)를 개발하여 검사를 실시하였다. 학년별, 성별 과학 인지모니터링 기능의 효율성에 차이가 있는지를 알아보기 위해 분산 분석과 Scheffe´검증을 실시하였다. 연구 결과에 의하면 2~4학년의 인지모니터링 기능은 63.4%, 4~6학년에서는 57.4%의 효율성을 갖는 것으로 나타났다. 인지모니터링 기능의 효율성을 학년별로 구분 할 때, 3, 4학년은 2학년보다 유의미하게 높게 나타났으며, 5, 6학년이 4학년보다 더 높게 나타났다. 성별로 보면 2, 3학년은 여학생이 남학생보다 높았으며, 4~6학년은 성별 차이가 나타나지 않았다. The purpose of this study was to investigate the effectiveness of cognitive monitoring skills of elementary students on science by the grade and sex. The subject of this study was 1001 elementary students of 2~6 grade from 5 schools. The instrument of study, TSCM Ⅰ(Test of Science Cognitive Monitoring Ⅰ) for 2~4 grade and TSCM Ⅱ for 4~6 grade were developed. The results of this study showed that the effectiveness of cognitive monitoring skills was 63.4% for 2~4 grade and 57.4% for 4~6 grade. The effectiveness of cognitive monitoring skills of 3 and 4 graders was significantly higher than 2, while 5 and 6 was higher than 4 graders. Girls were higher than boys for 2 and 3 grade, but 4?6 graders were not significantly different by the sex.

Objectives : In order to investigate the efficacy and safety of the newly developed herbal medicine Jetongdan, a placebo-controlled randomized clinical trial of patients with osteoarthriotis of the knee was undertaken. Methods : Data were obtained from 80 patients with OA of the knee. After the enrollment, they were asked to answer a disease-specific questionnaire (Western Ontario and McMaster Universities (WOMAC) OA index) and analyzed with the erythrocyte sedimentation rate (ESR) in order to evaluate the efficacy of Jetongdan, and analyzed for aspartate transaminase (AST) level, alanine transminase (ALT) level, blood urea mitrogen (BUN) level, and creatinine (Cr) level in order to evaluate the safety of Jetongdan. Results : The liver function and renal function did not deteriorate after treatment with Jetongdan. Composite WOMAC score and physical function subscale was improved, but pain subscale, stiffness subscale, and ESR were not improved by Jetongdan. This was possibly because the baseline characteristics of the two groups were not homogenized after randomization. Conclusions : Jetongdan could be a promising treatment option for osteoarthritis of the knee. Further study in a larger population with appropriate severity grades is recommended.
