Objective: This study was performed to examine the relationship between community-based social support and psychosocial distress in workers. Methods: The study subjects were 596 workers recruited from 11 companies in Chungju city. A structured questionnaire was used to assess sociodemographics, health-related behaviors, job characteristics, job stress, work-based social support, community-based social support and level of psychosocial distress. Results: Hierarchical multiple regression analysis showed that workers with no chronic disease, exercise and sufficient sleep had a higher score of psychosocial distress than those with chronic disease, no exercise, and not enough sleep. Coworker's work-based social support and community-based social support were negatively associated with psychosocial distress. The R square value of total independent variables on psychosocial distress was 0.409, and that of community-based social support on psychosocial distress was 0.052. Conclusion: This study showed that community-based social support served as a protective factor against psychosocial distress in some workers. We recommend the establishment of a worksite stress reduction program in occupational level as well as community-based social support.

Based on the observation on 20, 23 and 26 July 2004, the distributions of temperature, salinity and stratification was investigated in relation to ebb, turn of tide and flood. The results are as follows: 1) The high temperature and low saline water with 23.5-24.0℃ and 32.4~33.0psu existed at Naro Island. 2) The cold surface water below 21.00 and 33.0~33.4psu appeared in the area near Gae Island and Geumo Island. 3) The cold and saline water, below 24.0℃ at the surface and 17.0℃ near the bottom, 32.8~33.8psu at the surface and 33.8~34.0psu near the bottom, existed in Sori Island. These waters were more saline compared to the South Sea Coastal Water with about 31.8psu. This suggests that the oceanic saline water intruded into the Bottol Bada through the area near Sori Island. The stratification appeared during all the observation periods due to a high solar radiation of 22MJ/m², and a weak wind speed of 2.9m/s on the average while the mean speed of wind in July is around 3.9 m/s. It qualitatively suggested that the stratification was maintained during the observation periods because of a high solar radiation, a weak wind speed and intrusion of saline oceanic water.

최충식,채정호,우동원,최영희,함웅,이규항,장미화 대한신경정신의학회 2001 신경정신의학 Vol.40 No.1

연구목적: 정신분열병 환자에서의 재활치료는 개인의 극복 기술과 능력을 향상시키고 재발을 유발시킬 수 있는 스트레스의 부정적인 영향을 중화시킴으로써 질병의 만성화를 막고 사회기능을 호전시킬 수 있기에 점차 그 중요성이 대두되고 있다. 본 연구는 만성 정신분열병 입원 환자에서 재활치료의 하나인 단축형 증상관리 훈련이 정신장애에 대한 자기 인식에 미치는 효능을 알아보기 위하여 시행되었다. 방법: 정신분열병으로 진단받고 입원 중인 환자들에게 재발경고징후를 규명하는 것, 재발경고징후를 관리하는 것, 지속증상을 극복하는 것, 술과 불법 약물을 피하는 것 등으로 구성된 승인-UCLA 사회기술 및 독립적인 생활기술훈련 단위 중 증상관리단위를 기초로 한국실정에 맞게 축약한 증산관리 훈련을 주 1회, 60분씩, 4∼5주간 실시하였고 실시 전후에 전신장애 비인식 평가 척도(Scale to Assess Unawareness ofMental Disorder; 이하 SUMD)로 자신의 정신장애에 대한 인식을 평가하였으며 임상적 전반적 인상(Clinical Global Impression;이하 CGI)로 임상 상태를 조사하였고 각 인구학적 변인들을 조사하였다. 결과: 환자 30명이 훈련을 완수하였으며 이들의 평균 연령은 36.6±7.6세였고 남자가 14명(46.7%), 여자가16명(53.3%)이었다. SUMD 점수는 훈련 전 16.9±4.0점에서 훈련 후 12.9±4.2점으로 유의하게 줄어 정신장애에 대한 자기 인식 정도가 향상되었으며(p<0.01), CGI도 훈련전의 3.7±0.9점에서 훈련 후 2.8±0.8점으로 유의하게 호전되었다(p<0.01). 환자의 연령, 발병시 연령, 유병 기간, 입원 기간, 항정신병약물 사용 용량, 교육 정도, CGI로 평가한 임상 상태등은 정신장애의 자기 인식 정도와는 관련성이 없었다. 결론: 정신분열병 입원 환자에서 단축형 증상관리 훈련은 정신장애에 대한 자기 인식을 증가시킬 수 있는 방법이 될 가능성을 확인하였으며 이 방법이 정신분열병 재활치료의 중요한 요소가 될 수 있음을 알 수 있었다. Objectives : The purpose of this study was to examine whether Symptom Management Module-Korean Brief Version(SMM-B) is effective as a psychosocial treatment of the inpat-ients with chronic schizophrenia. We also questioned which of demographic and clinical characteristics could be predictors of differential treatment response. Methods : The subjects were composed of 30 inpatients with chronic schizophrenia, who were trained with weekly session of SMM-B for 5 weeks. Before and after the training, the level of psychopathology, knowledge about schizophrenia were assessed as dependent variables by using Clinical Global Impression(CGI) and Scale to Assess Unawareness of Mental Disorder(SUMD). Results : Overall, patients showed improvement over the treatment period on psychopath-ology as well as knowledge about psychosis. Total scores of SUMD were changed from 16.9±4.0 before training to 12.9±4.2 after training(p<0.01) and scores of CGI were improved from 3.7±0.9 to 2.8±0.8<p<0.01). Howver age, gender, years of education, age of onset, duration of illness, duration of admission, numbers of psychiatric admission, and clinical status evaluated by CGI were not correlated with unawareness of psychosis. Conclusion : These results suggest that SMM-B could be a reliable method to improve self-aw-areness of psychosis in patients whth chronic schizophrenia and one of important elements in rehabilitation.

생체내 흰쥐 해마 CA1 세포에서 가바성 억제에 대한 전기생리학 특성

가바성 억제 신경세포는 해마의 정상적인 기능을 조절하는데 중요한 역할을 하며 해마 병변을 유발하는 중요한 요소이다. 본 연구는 in vivo실험법을 사용하여 해마 CAI영역에서의 전기 생리학적 반응을 측정함으로써 가바성 신경세포의 기능을 분석하고 이를 슬라이스 실험법과 비교하고자 하였다. Fimbria-fonix 전기자극시 전형적인 Population spike가 나타났고 10μm bicuculline 존재하에서는 전기자극에 의해 burst 형태의 population spike가 나타났다. Population spike의 크기는 자극 강도에 비례하였으며 그 숫자도bicuculline 전극사용시와 같이 동일한 양상을 보였다. CAI영역의 흥분성 수준을 측정하기 위해 paired-pulse자극을 하였는데 짧은 자극 간격에서 억제성 반응을 보였고 burst형태의 afterdischarge를 나타내었다. CAI영역에서 in vivo 실험법을 사용한 가바성 신경세포반응의 결과는 추체세포의 흥분성 조절을 효과적으로 분석할 수 있으며 in vitro 실험법에 비해 기능적 평가가 더욱 이상적임을 알 수 있다. Inhibitory cells are critically involved in shaping normal hippocampal function and are thought to be important elements in the development of hippocampal pathologies. The present study was carried out in hippocampal CA1 area in vivo to compare with hippocampal slice studies. Intracellular and extracellular recordings with or without bicuculline electrodes were obtained in the intact brain of anesthetized rats, and cells were intracellularly labelled with neurobiotin. Electrical stimulation of fimbria-fornix resulted in an initial short-latency population spike. In the presence of 10μM bicuculline, orthodromic stimulation resulted in bursts of population spike. The amplitude of population spikes in the CA1 region increased with stimulus intensity. as did the number of population spikes when the field recording electrode contained 10μM bicucilline. We measured the level of excitability in the CA1 area, using a paired-pulse stimulus paradigm to evoke population spokes. Population spikes showed strong paired-pulse stimulus. These result suggest that hippocampal CAI inhibitory interneurons can affect the excitabillity of pyramidal neurons that can not be appreciated in conventional in vitro preparation.

The enrichment triad model(Renzulli, 1977) which was originally developed for teaching and learning of gifted and talented children consists of three types of enrichment activities. Type Ⅰ enrichment activities build knowledge for later use in 'gifted behaviors', and type Ⅱ enrichment activities focus on the 'how-to skills,' attitudes and values the student must develop to become and effective investigator, problem solver and producer. Type Ⅲ enrichment activities, the pursuit of real problems and realization of gifted behavior, are the fundamental goal for this model. In this study we developed enrichment activities for high school earth science class. We could summarize enrichment activities as follows: In studying the fossil section, after reporting their research activities on fossil data, students can understand the fossil theory through questioning and answering their homeworks. They can enhance their interest and curiosity by watching the movie 'Jurassic Part'(type Ⅰ enrichment activities). After making replica of fossil samples(type Ⅱ), they can write their research reports or articles concerning fossils(type Ⅲ). Students can extend their knowledge about fossils through these types of enrichment activities. In studying weather map section, after collecting newspaper clippings or searching internet, students present their knowledge about weather and weather maps(type Ⅰ enrichment activities). Learning how to make weather maps and investigating how to analyze them, student can extend their knowledge(type Ⅱ). Through these activities, students can apply their knowledge to everyday life experience(type Ⅲ). The third program is 'igneous rock' section. Students investigate the fossil formation in Korea(type Ⅰ enrichment activities). They can understand the principle of volcanic activities through experiment of volcano eruption model type Ⅱ. Through drawing pictures, writing assignment of experiment activities and playing the role play of igneous rocks, teachers can help students to acquire cause or interest to study the igneous rocks(type Ⅲ). In conclusion, within a classroom instruction teachers would be utilizing all three types of activities, moving from one to the other as class, and individual needs, demand. By selecting what students want to do and making them to produce results of their activities, we are expecting that teachers can cultivate creative thinking and enhance problem solving ability of students.
