남한 중남부에 위치하는 한국교원대학교 단주기 지진 관측망에 1997${\sim}$1998년 사이 포착된 원거리 지진들의 종파 초동 시간의 상대적 도달시간차를 분석하고 향후 있을 한반도 전체규모의 종파속도구조대비의 연구를 위하여 예비적인 토모그라피(tomography) 역산을 실시하였다. 각 지진 관측점에서 측정된 종파의 상대적 도달시간차들은 최대 0.7초로 측정되었다. 경기육괴와 옥천대의 경계 근처의 관측점들에서 계산된 종파의 상대적 도달시간차들은 역방위각의 변화에 따라 비교적 큰 값의 변화를 나타내며 그 지역 지각 하부에 속도구조 이상체가 존재할 수 있음을 지시한다. 조사지역 상부 맨틀이 수평적으로 균질하다는 가정하에 지각 전체에 대한 토모그라피 역산 결과는 조사지역 북서쪽에 북동-남서 방향으로 상대적으로 낮은 종파 속도를 가지는 구조가 나타난다. 역산된 예비적 성격의 상대적 속도 구조이상체는 경기육괴와 옥천대의 경계를 따라 대비되는 듯한 경향을 나타낸다. 이번 연구에 사용된 블록의 크기나 위치 등에대한 입력 파라메터는 차후 자료가 충분히 집적될 경우 정밀분석을 위한 입력 파라메터로서 이용될 것이다. P wave traveltime delays has been measured and a preliminary tomouaphic inversion has been performed using the data collected from the network deployed by Korea National University of Education in the southcentral part Korea. The maximum variation in relative traveltime residuals is almost 0.7 seconds. A large azimuthal variation in traveltime residuals is observed at the stations in the northwestern part of the study area. This might indicate the existence of lateral velocity heterogeneity beneath the study area. Although, the inverted tomographic image seems to be correlated with the tectonic boundary between Kyunggi Massif and Okcheon Belt, the confidence level is presently low. We should place on the importance of this study for finding preferable inversion parameters and predicting probable result. Better tomographic image of the study area can be obtained in the near future when the data are accumulated.

Depression is very common mental disorder, so many people suffer from it, which makes the treatment of depression important. Many drugs to treat depression were developed and being prescripted. But they have a lot of side effects, so it needs to develop drugs without side effects or with less side effects. Herbal medicines have been used to treat not only physical disorder but also mental disorder and it has been reported that they have less side effects. Therefore, there is the need to discover and use herbal medicine with antidepressant effect. The purpose of this study was to reseach Antidepressant effect of Licium chinense Mill. and its influence on serotonin and its metabolite of depression model rats. We used 'forced swimming test(FST)' to know antidepressant effect of Licium chinense Mill. and HPLC to check the influence on serotonin and its metabolite(5-HIAA) of Licium chinense Mill. after rats' brains were divided into cerebral cortex, striatum, hypothalamus and hippocampus. The results were obtained as follows : In the study of antidepressant effect by 'forced swimming test(FST)' method, Licium chinense Mill. had a significant antidepressant effect. In the study of influence on serotonin and 5-HIAA by HPLC, Licium chinense Mill. mainly increased serotonin and 5-HlAA of cerebral cortex and striatum signigficantly among 4 parts of rat's brain above-mentioned. These results suggest that Licium chinense Mill. has antidepressant effect that may be related with the increase of serotonin and its metabolite as its mechanism, but more precise experiments will be need to prove their relation.

일제 말 극단 현대극장의 국민연극 실천과 신극(新劇)의 딜레마

이덕기(Lee Duc-gi) 한국어문학회 2010 語文學 Vol.0 No.107

In march 1941, Hyundae-gukjang had brilliantly made its first step under the flag of the establishment of ‘Gukmin-yeonguk’. As a successor of Gukyeonjwa and Gukyesulyeonguhoi, it criticized conventional theatre companies mainly aimed for profits and advocated the true national art. Hungyongang and Bukjindae were two of the most representative theatre companies for its Gukminyeonguk, planned with great ambitions. Their effects, however, did not seem very huge, only to result in the withdrawal of some members and serious financial problems. Most of all, there were a clear contradiction and a dillema in Hyundae-gukjang just like in former Gukyeonjwa when Hyundae-gukjang tried to professionalize shinguk[one kind of Josoen modern drama]. Gukyeonjwa had been suspicious that local performances were necessary, even if it clearly had clarified the purpose to be a professional theatre, taking a belligerent position to many of the past successful theatre companies. Hyundae-gukjang as well tried to discriminate itself from other successful companies and to raise its status in the theatrical world. This policy contributed to financial problems from which the theatre company attempted to escape by depending on ‘a possible help from others’. As Gukyeonjwa had expected to get financial aids hoping for an appearance of a generous benefactor who would have great interest in plays, Hyundaegukjang wanted the Japanese Empire to financially support itself; however, it never happened, which ultimately led the theatre company to turn its way into popular repertories. In other words, the company decided to operate with its own efforts, also collaborating with some of the most successful theatre companies of those days, such as Sungbo-akukdae, Yakcho-gagukdan. Among the main repertory pieces were Ham-Seduk’s popular works and others’. In brief, Hyundea-gukjang’s early action was failed in professionalizing shinguk. With vague hope of external support, it was impossible. ‘Gukmin-yeonguk’ was sort method for external support and no more. Hyundea-gukjang’s change of direction means Gukmin-yoenguk they advanced was failed, and Hyudae-gukjang’s leadership and status were damaged seriously.

Objectives:This study was performed to evaluate the reliability and Validity of Korean version of Alcohol Use Inventory for the comprehensive assessment of alcohol dependence. Subjects and Methods:Subjects served for the study were 119 Korean alcoholic patients from 3 mental hospitals and 2 general hospitals. Their alcohol history and demographic data were taken and they were asked to fill up questionnaires of Korean version of Alcohol Use Inventory, MAST, ADS, MMPI and SCL-90-R. Results:In summary, the results of this study were as follows:1) Among the scales, the means of MENT ALIM, GREGARUS, HELPBEFR and ENHANCED scales were relatively high. On the other hand the means of GRE GARUS, AWARENES and RECPAWAR scales were relatively low. 2) In the internal consistency analysis, all the AUI scales except QUANTITY showed significant reliability. 3) In the correlation analysis for the test of concurrent validity, the scales associated with ‘motivation of drinking’ and ‘concerns about drinking’ were significantly correlated with the MAST and the ADS. 4) In the correlation with the MMPI and the SCL-90-R, most scales of AUI were significantly correlated with the psychopathology of the subjects. 5) Familial alcoholics were scored significantly higher than non-familial alcoholics in the the means of LCONTROL, ROLEMALA, DELIRIUM, GU ILTWOR, HELPBEFR, DISRUPT1, ANXCONCN and ALC INVOL scales. Conclusions:The results suggest that Korean version of Alcohol Use Inventory showed reasonable reliability and validity, therefore it may be effectively used in the assessment and treatment planning of alcoholic patients.

풍력에너지 연구개발은 1970년대 에너지 위기 이후 시작되어 1980년대 초반까지 가격 경쟁력과 기술 부족으로 상용화에 이르지 못하였다. 그러나 1980년대 중반 미국을 시작으로 상업발전에 성공하여 100kW급 풍력발전시스템이 대량 보급되기 시작하였다. 1990대에는 덴마크, 독일, 스페인 등에서 대규모 풍력시장이 형성되었고, 2000년대 들어 대형화에 성공하여 기존 발전에 대한 시장경쟁력을 확보하게 되었다. 본 논문에서는 풍력에너지 보급 확산을 촉진하기 위해 풍력발전 시장의 동향분석과 함께 기술 특성을 분석하였으며 보급 촉진을 도모할 수 있는 확산 전략들을 제시하였다.

Objectives:The purpose of this study is to classify the personality characteristics of individuals with alcohol dependence through cluster analysis, and to examine clinical characteristics of each subtype. Methods:402 Inpatients with alcohol dependence were received MCMI, AUI, MAST, and ADS. The classification of personality subtypes of alcohol dependence was done through the cluster analysis. Results:1) Personality characteristics of patients with alcohol dependence could be classified into three subtypes. Subtype 1 showed the most severe personality pathology. Subtype 2 showed the relatively milder personality pathology. Subtype 3 showed the intermediate level of personality pathology. 2) There is no difference in age, educational level, marital status, and the onset age of alcohol problem, and the existence or nonexistence of job, family history of alcoholism, medical disease, and smoking among three subtypes. 3) As a result of comparative analysis of alcohol-related variables, mental functioning, compulsive drinking, drinking problem, insight of problem, anxiety, and physical, psychological dependence showed statistically significant difference between subtype 1 and subtype 2 or 3. 4) There was a significant difference in anxiety, somatization, mania, alcohol dependence, posttraumatic stress symptom, thought disorder, major depression, and delusional disorder among three subtypes. There was a significant difference in the degree of drug abuse between subtype 1 and subtype 2 or 3. Conclusion:It is possible to classify personality characteristics of patients with alcohol dependence into three subtypes by means of MCMI in Korea.
