This study was planned to determine the subjective and objective refraction under Mydrin P (Sansei Do Pham. Co.) among 758 Korean high school girls in Seoul area age of 12 to 18 years. Brightness (illumination) of 6 class rooms out of 30 in junior high school and 11 class rooms out of 24 in senior high school was measured with a sight meter (Western model 703-60, type 7, Western Co.) and a sun light illumination meter (Western model 756, Weston Co.). 1. Among 758 high school girls, error was 80.34% and emmetropia 19.66%. 2. As to the distribution of refractive erros, 30.02% was hyperopic refractive error and 69.98% was myopic refractive error. 3. The incidence of each refractive errors was the following order: hyperopia 15.44%, myop4 37.40%, compound myopic astigmatism 15.04%, compound hyperopic astigmatism 5.54%, simple myopic astigmatism 3.23%, simple hyperopic astigmatism 2.9%, mixed astigmations 0.73%. 5. The incidence of refractive errors in relation to age reveals the myopic refractive error increases from 37.35% at the age of 12 years reaching to 97.06% at the age of 18 years, while the hyperopic refractive error decreases from 62.65% at the age of 12 years decreasing to 2.94% at the age of 18 years. 6. Emmetropia was most frequent at the age of 16 years and there after tends to decrease. 7. Hyperopic refractive error under 1.00D was 23.99% and myopic refractive error under 1.00D was 26.62%. 8. As to the type of astigmatism, "with the rule" was 52.88%, "against rule" 40.14%, "oblique" 4.33% and mixed astigmatism 2.64% only. 9. The brightness of classrooms reveals averaing 75.5 F.C. in senior high school and 30.2 F.C. in senior high school. The day light factor measured at the same time was average 6.2% in junior high school and 1.8% in senior high school. The balance of illumination measured at the sametime was average 69.8% in junior high school and 52.6% in senior high school.

The purpose of this study was to compare the comfort level between healthy people and adult in-patients in Korea. The sample consisted of 248 adults (healthy adults: 124, patients admitted in university hospitals in Seoul and Jinju: 124). The research tool used for the study was General Comfort Questionnaire(GCQ) which was developed by Kolcaba(1992) and was translated by Korean. The research tool consisted of 28 items (6 items on physical dimension, 9 items on psychospritual dimension, 7 items on environmental dimension, 6 items on social dimension). Data were analyzing using the SPSS, yielding t-test, ANOVA. The results are as follows: 1) Mean scores for comfort level in healthy adults were 2.92 on a 4 point scale. 2) Mean scores for comfort level in-patient adult were 2.72 on a 4 point scale. 3) There was a significant difference between the two groups on the comfort level. The healthy adults had higher comfort level than in-patients (t=4.44, p=0.000). 4) There was a significant difference between the two groups on the comfort level of physical and environmental dimension. The healthy adults had higher comfort level than in-patients (t=2.99, p=0.003) and environmental dimension (t=8.81, p=0.000).

BACKGROUND: Hemorrhage itself has been shown to produce abnormalities in immunity, particularly depression of the lymphocyte function. In order to better examine the amount of hemorrhage required to suppress the lymphocyte function, we determined the effect of graded fixed-volume hemorrhage on splenocyte proliferation and the lymphocyte subpopulation. METHODS: Male Sprague-Dawley rats(weight, 350~400g) were anesthetized, subjected to hemorrhages of 7.5ml/kg, 15ml/kg, and 22.5ml/kg by percutaneous cardiac puncture with 26G needles. After 1, 2, 4, and 7 days, animals were killed to obtain the blood and spleen. The splenocyte proliferative capacity was measured by using the tritiated thymidine incorporation technique, and the peripheral lymphocyte subpopulation was determined using flow cytometry with the following monoclonal antibodies: T cell(CD3+), T helper cell(CD4+), T cytotoxic cell(CD8+), and B cell(CD45RA+). RESULTS: Hemorrhage of 7.5ml/kg did not induce depression of splenocyte proliferation. However, for hemorrhage greater than 15ml/kg, the splenocyte proliferative capacity was significantly depressed at 2 days after hemorrhage and recovered at 4 days. Hemorrhage induced no changes in the relative percentage of lymphocyte subpopulations and in the number of each cell in peripheral blood. CONCLUSION: This study suggests that cellular immunity is depressed at 48 hrs after a hemorrhage greater than 15ml/kg without any change in the peripheral lymphocyte subpopulation.

A modern development of ambulatory ECG monitoring gave great advances in the diagnosis and evaluation of various cardiac conditions. Fifteen cases of ischemic heart disease, 11 cases of nonischemic heart disease, 5 cases of noncardiac disease and 9 cases of normal healthy subjects were studied from January 1980 to July 1981 in national Medical Center, with the following results: 1) The heart rate was decreased during night time, with less decreasing tendency in patients with ischemic heart disease. 2) Among 30 cases, including 12 patients with ischemic heart disease, who didn't show arrhythmia on routine 12 lead ECG, 12 cases, including 6 patients with ischemic heart disease, showed arrhythmia on Holter monitoring. 3) Among 5 cases with ischemic heart disease who showed premature ventricular contraction on day time monitoring, 2 cases didn't show premature ventricular contraction on nigh time monitoring. 4) The S-T segment and T wave were changed during night time in 2 cases with ischemic heart disease and in 2 normal subjects. From these results, we could assert that Holter monioring or ambulatory ECG tracing would be a good method for diagnosis and evaluation of ischemic heart disease, and other cardiac conditions. Several another studies with this equipment have to be performed and would give more distinctive outcomes.
