아동에 가해지는 정신적 외상의 충격은 아동의 심리발달에 지울 수 없는 상처를 남김으로써 향후 심각한 정신장애를 일으키는 결정적 원인이 된다. 아동기 외상의 현상학적 특징과 외상에 관여하는 신경생물학적 기전을 살펴보았고, 아동기에 경험하는 외상이 인격의 발달에 미치는 영향과 그와 관련한 정신병리를 알아보았다. 외상에 노출된 아동은 공통적으로 자신이 경험한 공포사건을 시각적으로 재경험하거나 그 기억을 반복하며, 놀이나 행동을 통해서도 외상사건을 반복하려는 경향을 보인다. 일회의 충격적 사건에 노출된 아동은 사건에 대한 지나친 기억과 집착을 보이고 지각왜곡이 심한 반면 장기간 반복되는 외상을 경험하는 아동은 정신적 무감각과 자기최면, 해리, 분노의 경향이 두드러진다. 소아·청소년에서는 외상 후 퇴행이 보다 현저하고 시간감각의 왜곡이 더 심하게 나타나며 아동의 연령이 어릴수록 자율신경계의 반응성이 증가하는 경향을 보인다. 외상적 충격에 노출되면 뇌내에서 즉각적이고 방대한 신경전달물질의 방출이 있게되는데, 자율신경계, 면역계, 시상하부-뇌하수체-부신피질 축(hypothalamic-pituitary-adrenal axis)이 활성화된다. 외상시 internal opiate가 활발한 작용을 하면서 아동으로 하여금 외상에 반응하지 않도록 하고 외상에 대한 감정반응 자체를 봉쇄할 수 있도록 해준다. 아동기 외상의 경우 central noradrenergic system에 변화가 초래되어 카테콜아민에 대해 과민감한 비정상적 소견을 보이게 된다. 체내 순환되는 cortisol 수치는 감소하고, glucocorticoid 수용체 농도와 반응성이 증가한다. 외상 후 발견되는 기억력 장애는 해마의 구조적 변화와 관련이 있는 것으로 보고되고 있다. 아동기 외상은 자기(self)와 대상(object)에 대한 내적 표상(internal representation)이 지속적으로 분화 발전하는 발달과정에서 일어난다는 점에서 인격의 발달에 심각한 영향을 미치게 된다. 해리, 신체화, 자학성, 자기애 장애의 정신병리로 발전하면서 경계성 인격장애, 자기애성 인격장애, 다중인격장애 등을 초래하게 된다.

본 논문은 펀드투자의 유입자금흐름과 유출자금흐름을 별도로 구분하여 결정요인을 실증분석하였다. 과거 성과, 펀드연령, 펀드규모, 판매보수 등 주요 요인의 자금흐름에 대한 효과는 유입자금과 유출자금 사이에 큰 차이가 있었다. 과거 성과와의 양(+)의 관계, 펀드연령과의 음(-)의 관계 등 순유입자금을 기반으로 한 기존 연구에서 확립된 실증 결과는 유출자금에 대해서는 반대로 나타났다. 특히 과거 성과의 유출자금과의 관계는 '처분효과(disposition effect)'의 존재를 시사하였다. 한편, '계열 펀드'와 '비계열 펀드'를 구분할 경우 판매보수의 유입자금과 유출자금에 대한 효과가 두 펀드그룹 사이에 상이하여, 판매사 간의 유인체계 차이가 펀드선택시장에서 중요한 요인인 것으로 나타났다. '처분효과'의 존재 등 본 논문에서 미국의 기존 연구와 다른 분석 결과가 얻어진 이유는 표본의 차이에 기인하였을 가능성이 있다.

The objectives of this study are to conceptualize theoretically and to examine empirically the interrelationships among channel member's satisfaction, dependence, and performance being immanent between dealing partners, by integrating behavioral and economic approach to explain comprehensively the interrelationship between dealing partners in conventional marketing channel which have not studied in previous studies. To attain above objectives, latent variables and observed variables which had been immanent between licenced dealers and wholesalers in fish marketing channel were found out by exploratory study, and pre-test was conducted to select the proper variables, and then the model which could explain the interrelationships among the variables was set up. Three categories of varables were considered in this study. Namely, economic and noneconomic factors were identified as independent variable, the degree of satisfaction and dependence to dealing partner as intervening variable, and performance as dependent variable. The data for the study was obtained from a survey questionnaire of 214 licenced dealers who work in Pusan, Yusoo, and Kunsan and 190 wholesalers who work in whole country. Among them, 264 anayzable questionnaires(including 154 licenced dealers and 110 wholesalers)were collected. Statistical procedure to analyze the data was carried out by LISREL version 7. Major findings obtained from the results of the analysis are as follows. First, economic variables have a great influence on the degree of both licenced dealers' and wholesalers' satisfaction. Among economic variables, the degree of keeping wholesalers' payment date have greater influence on the degree of licenced dealers' satisfaction, and licenced dealers' faculty being able to send good fish in quality have greater influence on the degree of wholesaler's satisfaction than other variables. In short, licenced dealers make great account of wholesalers' payment, and wholesalers make great account of licenced dealers' faculty being able to send good fish in quality in dealing relationship. Second, noneconomic variables have more relevance to the degree of dependence in both sides than economic variables. This means that noneconomic variables as well as economic variables can be a factor to keep up the dealing relationship. Third, the degree of satisfaction and dependence have influence on performance in both sides. In the licenced dealers' side, the degree of dependence have greater influence on performance than the degree of satisfaction, on the other hand, in wholesalers' side, the degree of satisfaction have greater influence on performance than the degree of dependence. This means that wholesalers can easily substitute their dealing partner for another licenced dealer comparatively.

The purpose of this study was to investigate the compliance behavior of hypertensive patients in light of their health belief model that explains an individual's compliance with health maintenance or getting well. Although there are many effective regimens and treatments for hypertension nowadays. the most important point to be taken to consideration in their behavioral aspect is their compliance with regard to the control of body weight. eating habits as to salt and cholesterol intake. stresses. activity patterns and smoking as related to their life style. The important reasons for the failure in the control of hypertensive patients are the complexity of regimens to be complied to. irregular medication and the life long restrictions in their own life style. The compliance of patients to medical regimens and rocommendations or failure to do so is an essential factor. Accordingly. the degree of the patient's compliance is an important determinant as to the success or failure of hypertension control. The subjects for this study were 187 hypertensive patients selected from admitted and out patients of the medical department at seven University Hospitals in Seoul. Data was collected from Dec. 1, 1979 to Feb. 15, 1980 using the questionaire method and was analysed by the use of means. standard deviations, coefficient of correlations, analysis of variance and multiple regression analysis. The results obtained are as follows A. Of the seven independent variables in light of health belief model. benefit. barrier and severity are closely related to patient's compliance behavior. Therefore these variables could be used as determinants to predict and modify the hypertensive behavior. 1. Benefit is the most important and significant of the variables for explaining the dependent variables. It accounts for the highest variance of patient's compliance. (23.62%) 2. Then taking the former together with barrier. the variance of compliance showed on increase. (26.59%) 3. And with the addition of severity to the first two. the variance of compliance was also increased. (28.l2 %) B. Except for susceptibility all the independent variables such as severity. benefit, knowledge. motivation and barrier are correlated to dependent variable compliance. C. Sex. marital status and religion appeared to have significant influence on the dependent variables. Therefore one could conclude that the more the patients are aware that hypertension is a threat to health. the more they understand the benefit of taking actions to prevent such a threat. and the less they perceive any barrier when taking action. the more compliant they become in following medical regimens and recommendations. Age. marital status and religion played a significant influence to their compliance. Accordingly. the selected structural variables and demographic variables which have influenced sick role behavior of the hypertensive patient must be integrated to teaching and counselling programs for better hypertension control.

Objective : The aim of this study was to investigate effects of Angelica gigas Nakai(AGN) on the ischemic injury by intraluminal filament insertion in the rats. Methods : The ischemia was induced by intraluminal filament insertion into middle cerebral artery. AGN herbal acupuncture into SP10 was carried out during 3 weeks after ischemic injury. Eight-arm radial maze was designed for the behavioral task. AGN herbal acupuncture showed neuroprotective agents in cresyl violet, acetylcholinesterase(AchE), choline acetyltransferase(ChAT) and nerve growth factor(NGF)-stain. Then check the effect of regional cerebral blood flow(rCBF) according to AGN herbal acupuncture in rats. Results : The errors in the eight-arm radial maze task were significantly decreased in normal group compared with control group on 1~6days, AGN2(0.02g/kg) herbal acupuncture group on 1~5days, AGN3(0.1g/kg) on 1~3days, AGN4(0.5g/kg) on 1, 3~6days. The rate of correct choice was significantly increased in AGN1(0.01g/kg) and AGN4 herbal acupuncture groups. The density of neurons in the hippocampal CA1 was the most increased in normal group and AGN1, AGN3, AGN4 herbal acupuncture groups compared with control group. The density of AchE in the hippocampal CA1 had a tendency to increase in all the groups when they were compared with control group, but not significant. The density of ChAT in the hippocampal CA1 was significantly increased in normal group and AGN1, AGN4 herbal acupuncture groups compared with control group. The density of NGF in the hippocampal CA1 was significantly increased AGN4 herbal acupuncture group compared with control group. The rCBF was significantly increased in AGN1, AGN3 and AGN4 herbal acupuncture groups without the change of blood pressure. Conclusions : These results suggest that AGN herbal acupuncture can be used for controlling stroke in early stage as herbal medication.

In ordo to investigate the professional job perception and job satisfaction of interns and residents and its related factors, the author conducted survey using self administered questionnaire for 2 months(August and September, 1996). The study subjects were 562 interns and residents who worked at one university hospital(tertiary hospital) and two general hospitals(secondary hospital) in Taegu, Korea. Among them, 297 (52.8%) responded completely. The results were as follows ; Respondents thought that people component was most important, science and status components were next among professional value scales which meant the desirable attitudes required to conduct professional works. But, the score of professional value scales was generally high and not affected by other variables in multiple linear regression analysis. They seemed to have very normative and ideal perceptions about professional values. The score of professionalism scales, which were attitudinal and behavioral traits about professional job, of high grade residents was significantly higher than that of interns and lower grade residents. The score of reference to professional organization and autonomy factor were increasing significantly as the grade increased. Working conditions and perception for socioeconomic status of doctors influenced the score of professionalism scale significantly. It seemed that professional socialization was made during the training periods of interns and residents. Most of respondents answered that current socioeconomic status of doctors were middle and high strata but they responded that the socioeconomic status of doctors would fall in the future. They seemed to have a pessimistic thought about doctor's status. Generally the respondents thought that they were satisfied with doctor job and fit to the job, but 51.9% answered that if possible they would get other jobs. It seemed to reflect their critical thinking on doctors' status. Perceptions about socioeconomic status of doctors, professional value and professionalism influenced job satisfaction significantly. The interns and residents had high sense of calling to doctors and thought that doctors were socially important job. Generally they were satisfied with their job. Interns and residents had normative thoughts about the trait which compentent doctors must have. During the training period, they seemed to have attitude and perception as a professional and to make professional socializations.

본 연구에서는 단각목의 일종인 소백옆새우(G. sobuegensis)를 대상으로 인공수로 하에서 pH 변화를 유도시킬 때 발생되는 개체의 표류행동에 대한 이동특성을 알아보았다. 본 종은 낮은 pH수준의 산성스트레스에서 회피행동이 현저하게 증가한다는 것을 알 수 있었으며, 또한 산성도에 따른 내성범위는 개체의 성숙도 즉 중소형보다 대형개체가 보다 민감하게 반응하는 것을 확인할 수 있었다. 특히 산성 스트레스에 의한 반응이 대형개체에 비해 소형과 중형개체에 있어서 매우 불규칙적으로 나타난 것은, 각종 수환경 변화에 대한 회피능력과도 같은 운동성의 차이 등을 고려해 볼 수 있었다. 전반적으로 인공 수로내의 소백옆새우 대부분 개체들은 전 시기에 걸쳐, pH4.5 이하의 낮은 수준에서 매우 민감하게 반응 한 후, 즉시 하류역 방향으로 수류의 움직임을 따라 능동적으로 회피 이동하는 특성을 보이는 것으로 나타났으며, pH3.0 이하의 강한 산성 스트레스 하에서는 오히려 회피능력을 상실하는 것으로 보여졌다. 또한 ANOVA분석결과, pH(F=353.415, p<0.0005)이외의 몇몇 환경 요인들 중 수온(F=66.596, p<0.0005)과 각 개체의 크기(F=71.386, p<0.0005)등도 낮은 산도에 의한 소백옆새우의 회피행동에 큰 영향을 미치는 주요한 요인이라는 것을 확인할 수 있었다.
