權純錫,金奉坤,柳秉郁 東亞大學校 1988 東亞論叢 Vol.25 No.1

A Study has been conducted experimentally on natural convection heat transfer charact-eristics for various Rayleigh numbers at vertical and horizontal plates with the rectangular corner. The results are as follows: 1) While temperature field is formed by the interaction of the heated fluid between verti-cal and horizontal plate, thermal boundary layer is pulled to the vertical plate near co-rner. 2) In case of constant Rayleigh number, the mean Nusselt number of the vertical plate is 28.8% more than that of the horizontal plate at ??. 3) Local Nusselt number increases at the trailing edge of the vertical plate and the lea-ding edge of the horizontal plate but decreases at the corner combined in vertical and horizontal plates. 4) In the vertical plate, the mean Nusselt number has a similar tendancy, but has 38.5% less than by the results of Schmidt and Beckman's study at ??. 5) In the horizontal plate, the mean Nusselt number has a similar tendancy, but has 38.4%iess than by the results of Rotem and Classen's study at ??.

404 nurses and nurse-aids rated their experiences of 45 symptoms(Moos' Menstrual Distress Questionnaire) of the menstrual, premenstrual and intermenstrual phase on a 4 point scale separately. The 45 symptoms were inter-related and factor analyzed separately for each phase. six common clusters of symptoms emerged from 3 phases, which were labeled concentration, motor tension, pain, pleasurable affect, autonomic reactions and water retention. Four clusters of symptoms emerged from premenstrual phase. These clusters were labeled instabillity, withdrwal reactions, depression and headache. The factor named unpleasurable affect emerged from intermenstrual and menstrual phase. Above findings were differed from the results of Moos' study in which eight basically replicated clusters of symptoms emerged from three phases. Through discussion of validity of this scale, and differences between results of Moos' and this study, we came to the conclusion that sampling of subjects, prospective longitudinal symptoms reporting, amount of variance in a symptom over the course of menstrual cycle and proper choice of factor analysis method would be salient variables to construct valid scale for measuring menstrual cycle symptoms.

The purpose of the study was to determine whether a 15.6mg.Kg ??' does of glutamate given one hour prior to incremental exercise test would reduce the lactate formation. Five well trained cyclists served as subjects in this experiment which included a placebo and glutamate trial. The subjects initially work on treadmill 200m/min for 3 minutes and here increased the workload by 20m/min every 3minutes until exhaustion. Blood lactate were collected from finger-tip. Subjects in the glutamate trial showed significantly lower lactate formation during exercise then they did in the placebo trial. In both groups no significant difference was found on heart rate. During the recovery lactate and heart, rate were unaltered in either the glutamate or placebo trials. In summary, glutamate ingestion may reduce lactate formation resultly improvement of performance.

연구목적 : 협조적이고 비주장적이며 인내심이 많고 부정적인 감정(특히 분노)을 잘 표현하지 않는 C형 성격 또는 1형 성격특성과 암 발병과의 관련성에 대해서는 일치된 결과가 없는 실정이다. 특히, 대장암 환자를 대상으로 이루어진 연구는 소수이며 분노의 억압 및 부정이 암 발생과 관련을 보였던 연구결과가 보고되었던 것과 대조적으로 공격적 적대감이 대장암 발생과 관련이 있다는 상반된 연구결과가 있다. 본 연구에서는 대장암 환자를 대상으로 1형 성격과 대장암 발병과의 관련성을 살펴보고, 분노의 경험과 표현 특성을 세분화하여 평가해서 암 발병과의 관련성을 밝혀 보고자하였다. 방 법 : 대장암 환자 35명과, 정상인 37명을 대상으로 Grossarth-Maticek의 성격-스트레스 검사 단축형중, 1형 성격을 반영하는 10문항과 Spielberger의 분노 검사 44문항을 이용하여 양군을 비교하였다. 자료 분석을 위해 환자 집단과 정상 집단 간 차이를 보고, 환자 집단과 정상 집단을 가장 잘 판별해줄 수 있는 변인을 찾기위해 판별분석을 실시하였다. 결 과 : 대장암 환자집단이 정상집단에 비해 분노 경험, 상태 분노, 분노 기질의 총점이 유의한 수준에서 높았고 그외의 다른 소척도나 1형 성격 스트레스 검사에 있어서는 유의한 차이는 나타나지 않았다. 판별분석 결과, 분노 기질 변인만 환자집단과 정상집단을 유의하게 판별하였다.(정준상관계수=.33, 판별율=65.8%). 결 론 : 평상시에 특별한 일 없이도 생리적 각성 상태를 동반하는 분노를 자주, 심하게 경험하는 특성과 대장암 발병이 관련성이 있음을 시사한다. Objectives : Although previous studies have suggested that Type 1 or Type C personality may be associated with the development of cancer, the results have not been consistent. There have been some evidences that repression, denial, or non-expression of anger are related with the incidence of colorectal cancer. However, according to the results of recent researches, aggressive hostility was related to the development of colorectal cancer. This study attempted to delineate psychological characteristics or personality patterns of the patients with colorectal cancer based on multidemensions of anger and Type 1 personality for cancer development. Method : The subjects were composed of 35 patients with colorectal cancer and 37 normal controls. Grossarth-Maticek personality questionnaire and the Spielberger state-trait anger expression inventory were administered. Results : In comparison with the normal control group, the colorectal cancer patient group showed significantly higher scores on anger experience, angry temperament and state anger but no significant differences on Type 1 personality scale and other subscales. In the discriminant analysis patients and control groups were classified by means of state anger, angry temperament, angry reaction, anger-in, anger-out and anger control variables. When angry temperament variable was selected as a discriminant variable, 65.8% of cases had been correctly classified. Conclusions : These results suggested the relationship between the disposition to experience and express anger without particular provocation and the development of cancer.
