In this thesis examine and analyze the items for the absent oneself from tests in the rule of school record about each senior high school in Cheju area, and then fair rules in statistics are suggested. Real data were collected from all schools in this area and they were compared and tested by experimental methods. The best idea is ①M2 for 3 more tests in one semester and ②M1 or M7 for 2 tests. and those are shown in main results.

To evaluate the effect of stress on immunological functions, lymphocyte subpopulation measure by flow cytometry technique, lymphocyte stimulation test using Con A and PHA, and the NK cell activity measure were performed on 12 medical students during test and vacation periods. The results were as follows : 1. The scores of GARS, SAS and SDS were significantly increased during test compared to the vacation periods (P<0.001). 2. There were no differences in the absolute numbers and percentages of the total lymphocyte, B-cell, T-cell, T-cell subset and NK cell between the test and vacation periods. 3. NK cell activities were significantly decreased during the test periods compared to the vacation periods (P<0.001 or P<0.01). 4. Lymphocyte proliferation response by PHA was significantly decreased during test periods compared to the vacation periods (P<0.05). 5. There were no significant correlations between the amount of increase in stress and the amount of decrease in NK cell activity or lymphocyte proliferation response.

In recent years, it has been believed that the DNA synthetic time (S-phase) is between 7 and 9 hours, however, the reports on this subject were vastly variable and also variable on G_2-phase (postsynthetic time) We presumed that S-phase would not be constant but S+G_2 phase would be constant. And we estimated the percent of labeled mitosis with one day postnatal chick stomach, and calculated as followings: 1. The S-phase was 4.5 hours, G_2-phase was 8.8 hours. 2. Minimum S-phase was 3 hours. 3. The total generation time was 19.5 hours and similar with the other reports, and the second curve was irregular, so it was computed by means of a formula using the labeling index and S-phase. It could be concluded that there were some relations between shortened S-phase and prolonged G_2-phase, and S+G_2phase were constant, however, it is needed more consideration and further study.

To investigate the components of general health in schizophrenia, the author applied the Korean version of Goldberg and Hillier's General Health Questionnaire on the 57 schizophrenic patients, and tried factor analysis using SPSS/PC+based on the scores of each items. The result of factor analysis were summarised as following 6 factors: Factor 1 was somatic symptoms and depression factor, factor 2 was indecisiveness factor, factor 3 was role dysfunction factor, factor 4 was insomnia factor, factor 5 was neurasthenia and escape factor, and factor 6 was nervousness and inefficiency factor. This results were thought to be as the concentration of genreal health in schizophrenia.

Retroperitoneal fibrosis is a fibrotic process of the retroperitoneum that frequently produces ureteral obstruction. It can occur as an idiopathic disease or in association with various non-malignant and malignant condition. In the early phase of the retroperitoneal fibrosis ; symptoms originate from the disease process itself, while in the late state the clinical features represent the effect of obstructive uropathy and renal failure. Treatment consist of steroid therapy, urinary diversion and ureterolysis with jntraperitonealization or lateralization or wrapping with omentum. Herein we present 5 cases of retroperitoneal fibrosis.

Endothelin(ET) is a 21-residue peptide originally isolated from the cultured porcine endothelial cells. There are at least three genes for endothelin:endothelin-1(ET-1), endothelin-2(ET-2), and endothelin-3(ET-3). Endothelins are present in various human biological fluids including plasma, urine, breast milk, and saliva and have been found elevated plasma ET concentrations in patients with diabetes mellitus, Patients undergoing maintenance hemodialysis due to chronic renal failure, patients with acute myocardial infarction, and patients with subarachnoid hemorrhage. Endothelial cell damage is suspected to occur in diabetic patients and may be one important cause of angiopathy, a major complication in diabetes mellitus. The elevation of ET in diabetic patients may be a marker of, and further exacerbate, their vascular disease. We measured the levels of ET-1 in plasma of 50 patients with non-insulin dependent diabetes mellitus(NIDDM) and 25 normal subjects by radioimmunoassay. The plasma ET-1 concentration (mean±S.D.) in NIDDM was 6.461 A2.510 f㏖/ ㎖, and was significantly higher than in normal subjects (4.567±1.155f㏖/㎖) (P<0.05). The plasma ET-1 concentration (mean±S.D.) in diabetic retinopathy group( 7.15±2.454 f㏖/ml) was significantly elevated than those in otherwise uncomplicated groups (5.348±2.390 f㏖/㎖)(P<0.01). The correlation between any clinical parameters and plasma ET-1 levels in NIDDM was not significant, In conclusion, this study suggest that the elevated levels of ET-1 in diabetic patients may be play a important role in the pathogenesis of diabetic complications.

In this paper, we report some sorts of result obtained by investigating the exhibits which had been submitted for "The National Exhibition of Science"and "The Science Exhibition for the Students of Cheju-do"during the last ten years and by putting the questions to the science teacher of the teacher of the middle and high schools in Cheju-do. Up to the half number the exhibits are occupied by the field of physics and biology. Almost the exhibits (above 90%) have the contents related to those of the current curriculum. However, 30.2% of the respondents only believe that their students may put the exhibits to practical use in learning. Many respondents replied that they could have not participated in the exhibition of science because they were in heavy duty and the fiscal support were not only so limited but also not sufficient enough to make an excellent work.
