Objectives : This study aimed to examine a correlation between the somatic complaints, emotion, vocabulary and alexithymia as a component of personality in normal persons. Methods : 204 subjects were collected by age-based systematic sampling from the 662 persons without confirmed medical illness. We used the Korean version of 20-item Toronto Alexithymia Scale(TAS-20K) to measure alexithymia. The somatic complaints were checked by the list of somatic symptoms on the diagnostic criteria of somatization disorder and major depressive episode in DSM-IV. The vocabulary was evaluated by the total number of associating-words from the spontaneous association of word and the secondary association to given words. The anxiety and depression were evaluated using 5-point self-report scale. Results : 1) The degree of alexithymia was significantly correlated with the somatic complaints, anxiety, depression. 2) The somatic complaints were significantly correlated with the anxiety and depression. 3) The number of associating-words showed negative correlation with the age. 4) The degree of alexithymia was not correlated with the number of associating-words. Conclusion : The more degree of alexithymia increased, the more somatic complaints appeared. There was a significant correlation between the degree of alexithymia, anxiety and depression. But the degree of alexithymia was not correlated with the amount of vocabulary. 연구목적 : 본 연구는 정상 성인에서 성격의 일반적인 특정으로서의 감정표현불능증과 신체적 호소, 정서상태 및 어휘와의 상관관계를 알아봄으로써 감정표현불능증에 대한 이해를 넓히고자 하였다. 방법 : 신체적 질환을 가지고 있지 않은 정상 성인에서 한국판 20항목 Toronto 감정표현불능증 척도(TAS-20K), 신체적 호소, 연상한 단어의 수, 우울과 불안을 정도를 측정하여 그 결과들간의 상관관계를 알아 보았다. 총 662명을 평가한 후 체계적 표본추출 방법을 이용하여 다시 204명을 선택하였다. 결과 : 1) 감정표현불능증의 정도는 신체적 호소, 불안, 우울의 정도와 유의한 상관관계를 보였다. 2) 신체적 호소는 불안, 우울의 정도와 유의한 상관관계를 보였다. 3) 연상한 단어의 수는 나이와 부적 상관관계를 보였다. 4) 강정표현불능증의 정도는 연상한 단어의 수와 유의한 상관관계를 보이지 않았다. 결론 : 감정표현불능증의 정도가 심할수록 신체적 호소는 더 많으며 이는 불안, 우울의 정도와 연관되어 있었으나 어휘의 양과는 유의한 관계를 발견할 수 없었다.

Small hydropower attracts attention because of its clean, renewable and abundant energy resources to develop. However, suitable draft-tube type is not determined yet because of its complicated internal flow and unstable turbine performance at the partial flow rate by the influence of the draft tube. Therefore, it is necessary to study the influence of draft tube shape. The purpose of this study is to investigate the influence of the draft tube shape to its internal flow using CFD analysis. The results show that large secondary flow occurs at the curve area of the draft tube and the secondary flow goes out to the outlet of the draft tube in the case of no-prerotation condition of the inlet flow.

Objectives : In 2002, the Korean Medication Algorithm Project for Major depressive Disorder (KMAP-MD) was published, but there has been a need for a guideline about detailed issues of depressive disorder. We revised KMAP-MDD andreestablished Korean Medication Algorithm Project for Depressive Disorder (KMAP-DD) in 2006. Methods : A questionnaire had been developed by the executive committee for KMAP-DD. The review committee consisted of 101 experienced psychiatrists. From the total of 22 questions in the questionnaire, 7 questions were evaluated for these subjects . We classified the expert opinions to 3 categories according to its confidence interval; first, second and third line. Results : SSRI and venlafaxine were the first line antidepressants (AD) for atypical and melancholic depression. For dysthymic disorder and minor depressive disorder, SSRI was recommended as the first line medications. Only AD medications was a preferred initial strategy for treating premenstrual dysphoric disorder, mild to moderate and severe non-psychotic postpartum depression. In severe psychotic postpartum depression, combination therapy of AD and atypical antipsychotics was the treatment of choice. SSRI was preferred when considering sedation, anticholinergic and cardiovascular adverse effects. Also, experts recommended mirtazapine against gastrointestinal adverse effects and bupropion in avoiding sexual dysfunction. Conclusion : These results suggest that clinicians have to consider both clinical situations and drug adverse effects in the choice of antidepressant medications.

배경 : 이 연구의 목적은 정신분열병 환자의 신체증상과 인구통계학적, 임상인자들과의 관련성을 알아보기 위함이다. 방법 : 연구 대상군은 입원중인 63명의 정신분열병 환자를 대상으로 하였다. 신체 증상의 정도는 한국어판 신체증상목록을 사용하여 측정하였다. SPSS 11.5를 이용하여 신체증상의 정도와 우울, 불안, 교육정도, 적응상태와의 관계를 피어슨 상관분석을 통하여 평가하였다. 결과 : 1) 신체증상의 정도는 교육기간과 입원 당시의 적응 상태와는 부적 상관을 보였다(p<0.05). 2) 신체증상의 정도는 우울, 불안과는 정적 상관을 보였다(p<0.05). 3) 정신분열병 환자의 신체 증상의 빈도는 다음 순이었다: 두통, 피로, 수면장애, 건강염려, 현기증, 오심, 위장장애, 근력 약화, 허리나 등의 통증, 복부의 가스. 결론 : 정신분열병의 신체증상의 정도는 교육기간이 길고 입원 당시의 적응상태가 좋을수록 감소하였다. 그리고 신체 증상은 우울, 불안의 증상이 심할수록 증가하였고, 이는 특히 신체증상이 우울, 불안과 관련이 있다는 것을 알 수 있었다. Background : The purpose of this study was to examine the correlation between somatic symptoms and demographic and clinical variables in schizophrenia patients. Methods : The subject were 63 schizophrenia patients ; male(n=35, mean age =39), female(n=28, mean=age 40). The degree of somatic symptoms was measured using the Korean versions of Wahler Physical Symptom Inventory(WPSI). The relationship among somatic symptoms, anxiety, depression, education period and adjustment was evaluated by Pearson correlation with SPSS 11.5. Results : 1) The degree of somatic symptoms showed negative correlation with education period and current adjustment at admission(p<0.05). 2) The degree of somatic symptoms was significantly correlated with degree of the depression and the anxiety(p<0.05). 3) The frequent somatic symptoms were as follows in order : headaches, feeling tired, difficulty sleeping, poor health in general, dizzy spells, nausea, intestinal or stomach trouble, muscular weakness, backaches and excessive gas. Conclusion : The somatic symptoms of schizophrenia were decreased in the group of the long education period and the good current adjustment at admission. The more depression and anxiety were increased, the more somatic symptoms were revealed. It suggests that somatic symptoms of schizophrenia may be related to depression and anxiety.

우울 증상을 수반한 만성 정신분열병 입원환자에서의 Paroxetine 효과 : 이중맹검 위약대조 연구

한평주,백영석,오상우,전현태,김지영 대한신경정신의학회 2000 신경정신의학 Vol.39 No.4

연구목적: 우울 증상이 있는 만성 정신분열병 환자를 대상으로 항정신병약물과 항우울제인 paroxetine 20mg을 병합 투여하여 우울 증상, 양성 증상, 음성 증상 및 일반적인 정신병리의 호전 여부를 밝히고자 하였다. 방법: DSM-IV 기준상 정신분열병으로 진단된 입원환자 중 우울 증상이 있는 49명을 대상으로 parox-etine과 위약을 이중맹검을 대조한 전향적 임상 연구로서 Hamilton Rating Scale for Depression (HRSD), Brief Psychiatric Rating Scale(BPRS), Positive and Negative Syndrome Scale (PANSS), Extrapyramidal Symptom Rating Scale(ESRS), UKU side effect rating scale(UKU), Clinical Global Impression(CGI)을 기저선과 1주, 2주, 4주, 6주의 시점에서 다섯 번 반복 측정하여 비교 검토하였다. 결과: 36명의 환자가 6주간의 실험을 마쳤다. Paroxetine군과 위약군을 비교해볼 때 HRSD 총점은 양군에서 의미있게 감소되어(p<.01) 우울 증상이 호전되었으나, 두 군간에 통계적으로 의미있는 차이는 없었다. 시간경과에 따라 항우울 효과는 paroxetine 군에서는 2주, 위약군에서는 4주 후부터 관찰되었다. 그리고 paroxetine군과 위약군 모두 PANSS 총점(p<.01)과 CGI 점수(p<.05)가 감소되어 전반적인 정신병리의 감소와 전체적인 임상적 호전을 보였으나, 두 군에서 양성 증상, 음성 증상, 일반적인 정신병리 그리고 약물 부작용은 유의미한 차이가 없었다. Paroxetine군에서 반응군고 비반응군으로 나누어 비교했을 때, 반응군이 비반응군보다 HRSD의 총점(p<.01)과 우울한 기분, 자살, 정신적 불안, 죄채감의 세부 항목에서 유의한 호전을 보였고(p</01),일과 활동, 초기 불면증, 건강염려증의 세부 항목이 호전되어(p<.05) 현저한 우울 증상의 호전을 보였다. 또한 반응군이 비반응군보다 BPRS 총점(p</01)과 PANSS의 일반적인 정신병리 점수(p<.05)가 낮게 나와, 일반 정신병리의 호전을 보였다. 결론: Paroxetine군과 위약군 모두에서 우울 증상의 감소가 있었지만, paroxetine군에서 항우울 효과가 빠르게 나타났다. 두 군간에 양성 증상, 음성 증상, 일반적인 정신병리와 부작용에 대한 차이는 없었다. Paroxetine군에서 반응군은 비반응군보다 우을 증상과 일반적인 정신병리에서 유의한 호전을 보였다. 즉 우울한 기분, 자살, 정신적 불안, 죄책감, 일과 활동, 초기 불면증, 건강염려증이 심한 정신분열병 환자에게 우울 증상을 회복시키는데 paroxetine 20mg의 병용 투여가 효과가 있었다. Objectives: This double-blind placebo-controlled study was conducted to demonstrate the improvement of depressive, positive and negative symptoms, and general psychopatholgy in depressed chronic schizophrenic inpatients with adjunctive paroxetine 20mg therapy in the morning. Methods: Forty nine chronic schizophrenic inpatients with depressive symptoms were randomly received adjunctive paroxetine of placebo for 6 week study period. Therapeutic effect and side dffects were evaluated by means of the Hamiltom Rating Scale for Depression(HRSD),The Brief Psychiatric Rating Scale(BPRS), the Positive and Negative Syndrome Scale(PANSS), the Extrapyramidal Symptom Rating Scale(ESRS), the UKU side effect rating scale(UKU), and the Clinical Global Impression(CGI) at baseline, first, second, forth, and sixth week of treatment in a controlled double-blind design. Results: 18 patients completed six weeks of paroxetine therapy, and 18 patients placebo therapy. 1) Comparison between paroxetine and placebo groups: (1) HRSD total scores in both groups were significantly decreased(p<.01) but there was no statistically significant difference between 2 groups. This study showed that significant effect in paroxetine group appeared at 2nd week of treatment(p<.01), while in placebo group at 4th week of treatment(p<.01). (2) PANSS, BPRS< CGI, ESRS, and UKU : In both groups, PANSS total scores and CGI scores were significantly decreased respectively(p<.01, p<.05) and thus indicated th im-provement of global psychopathology and entire effects. There were no significant differences between 2 groups in positive, negative symptoms, general psychopathology, and drug side effects. 2) Comparison between responding and nonresponding groups in paroxetine adjunctive therapy : (1) Compared with nonresponding group, responding group had significant decrease in HRSD total score(p<.01), in HRSD subitems such as depressed mood, suicide, psychic anxiety, and feelings of guilt(p<.01), and in other subitems such as work and activity, early insomnia, and hypochondriasis(p<.05). (2) Compared with nonresponding group, responding group had significantly decrease in BPRS total score(p<.01) and in general subscale of PANSS(p<.05). Conclusion: The results suggest that both paroxetine and placebo groups were improved in depressive symptoms, but paroxetine group had more rapid improvement than placebo group. There were no significant differences in positive symptoms, negative symptoms, general psychopathology, and drug side effects between two groups. Compared with nonresponding group in paroxetine adjunctive therapy, responding group had significant improvement in depressive symptoms and general psychopathology.
