To find elements which enable improving Quality of image of chest radiography, we attempted to make comparison between chest radiography used currently with that of the past, and following conclusion was reached: 1) It could be confirmed that a dependance on chest radiography was declining, because proportion of chest radiography against overall radiography decreased. 2) There was a change of kVp to a high voltage in a chest radiography, and use of high kVp became a generalization 3) Exposure time was reduced and exposure dose was curtailed accordingly. 4) Apparatus was mainly comprised of 3-phase rectifier circuit and inverter type. 5) It could be confirmed that frequency of applying additional filters for high kVp radiography was insufficient. 6) There was almost no difference in the condition of exposure between hospitals using film/screen and hospitals using CR. But when CR is used for radiography, it was increase in exposure dose due to increase in tube current and it will be necessary to have continuous study on exposure dose by an increase use of CR in the future.

Estrogen is believed to decrease coronary artery disease. Protein kinase C-α(PKCα)appear to be important in signal conduction pathways. Estrogen treatment increases catalytic activity of PKCα,and activation of PKCαcan modulate estrogen receptor levels and responsiveness. And it was reported that activation of PKC can protect cells from apoptosis induced by Fas ligation. But the beneficial effect of estrogen on PKCαwas not clearly demonstrated. The objective of this study was to evaluate the role of PKCαafter ovariectomy and estrogen therapy in rat aorta. The results were summarized as below: 1. The significant pathological changes were not observed in the rat aorta irrelevant to ovariectomy and estrogen therapy. 2. The expression of Fas was decreased in the aorta of estrogen-treated rats than that of ovariectomized rats without estrogen therapy. 3. Increased expression of PKCαwas more marked in the aprta of estrogen-treated rats than that of ovariectomized rat without estrogen therapy. In conclusion,PKCαmay be important in signal conduation pathway on the effect of estrogen. Activation of PKCαby estrogen reduced Fas expression, suggesting that PKCαactivation may play a role in protection against atherasclerosis. Further studies are needed to elucidate the role of PKCαafter estrogen therapy.

Purpose : Diabetic nephropathy is a serious complication of diabetes and accounts for much of its morbidity and mortality. It is well known that the overt clinical phase of diabetic nephropathy is preceded for many years by the presence of microalbuminuria. Microalbuminuria is thought to be a marker of widespread vascular damage and may underlie the propensity toward severe extrarenal vascular disease in microalbuminuric patients. Metalloproteinase-9 has a broad substrate specificity for native collagens as well as proteoglycan and elastin. One study reported that an increased plasma metalloproteinase-9 concentration precedes the development of microalbuminuria in type 2 diabetic patients. Another study reported that a high glucose concentration cause a abnormality on the activity of metalloproteinase by the mesangeal cell. The purpose of the present study was to examine whether palsma metalloproteinase-9 concentrations are altered at various complications in type 2 diabetic patients. Methods : Sixty patients with type 2 diabetes and thirty healthy control were recruited for the present study. No patient had any malignancy or history of heart disease, liver disease, collagen disease. We recorded age, duration of diabetes, and blood pressure. After an overnight fast, blood was drawn from an antecubita1 vein of measurement of glucose, metalloproteinase-9, HbA1C, and serum creatinine. To measure plasma concentration of metalloproteinase-9, a one step sandwich enzyme immunoassay using two monoclonal antibodies was used. Patients were divided into two group according to the presence or abscence of microalbuminuria. The groups were then compared with regard to clinical and laboratory characteristics and serum concentration of metalloproteinase-9. Results : The mean serum levels of metalloproteinase-9 in diabetic patients (62.32±25.83ng/㎖) were significantly higher than in healthy controls(12.92±4.97ng/㎖) (p<01). The mean serum levels of metalloproteinase-9 in diabetic patients with microalbuminuria(81.16±41.43ng/㎖) were significantly higher than in those with normoalbuminuria(31.48±7.34ng/㎖) (p<01) and much more than in healthy control(12.92±4.97ng/㎖) (p<05). Furthermore, the severity of nephropathy were closely associated with the serum metalloproteinase-9 level and the serum metalloproteinase-9 level was significantly correlated with microalbuminuria. The mean serum level of metalloproteinase-9 in diabetic patients with retinopathy(61.74±39.07ng/㎖) was significantly higher than in those with no retinopathy(34.98±9.02ng/㎖) (p<05). But, in diabetic patients with normoalbuminuria, there is no difference between the groups with retinopathy versus no retinopathy. Conclusion : In summary, a sustained increase in serum metalloproteinase-9 in patients with type 2 diabetes is associated with a high risk for the development of microalbuminuria. The results of this study suggest that the serum rnetalloproteinase-9 was a useful and noninvasive marker for the development of diabetic nephropathy. It could be also used to predict the development of diabetic complications and to assess therapeutics or the prognosis of diabetes. The usefulness of this model will be clarified by a larger scale and serial study.

The POE (Post Occupancy Evaluation) was carried out to provide basic behavioral knowledge for its planning and management of the Rose garden at Yong-In Farmland. Through its users a total of 1545 questionnaire were completed. They were designed by four sets of variables, such as behavoir pattern, motivation for visting, post-use evaluation, and users demographic variables. The findings are as follows: Firstly, descriptive statistics were employed to analyze behavoir pattems and users' demographic varialbes. As a result, 86% of visitors lived in Kyoung-Ki Do and Seoul : most of the vistiors is in their twenties and thirties : most of visitors were accompanied by their families, relatives and lovers : 66% of vistiors came by cars to Yong-In Farmland : 47% of visitors stayed for 1-2 hours in average. Secondly, factor analysis was used in order to group satisfaction factors. Five factors are : 'manegement of the garden', 'rose appearance', 'design and aesthetics', 'lighting and sound', and 'theme display'. Thirdly, regression analysis was used to examine the sources of satisfaction. The results of regression analysis shows that 42% of total variances was explained by ten variables. The most effective variable is 'the aspect of rose condition and appearance'. The overall evaluation for the new rose garden was 'satisfied' though the level of the 'satisfied' varies according to their ages. Twenties and thirties prefer that image of fantastic European style which was frequently showed on T.V or movies. Forties and fifties like more abudant scenery of roses of an Europenan style garden but unsatisfied with shortage of roses.

As society has been changing rapidly, so the evaluation of women's position and the value of leisure has been changing. Women's demanding of leisure activities is also increasing today. I studied on the factors which have effected on the satisfaction of leisure time's married women in cities with involvement of leisure and sports activities. The results are as follows ; 1. Married women's leisure and sports activities by ages & educational level. (a) As for married women in cities, the older they are the more they took experiences in sports activities for a year. I think it is desirable but in health care it is concerned that young married women in cities don't take part in sports activities. (b) The higher their ages are, the more time is required for exercise in a time. (c) The old age group at 60s expressed the most active attitudes in joining sports clubs. (d) The young age group of 20s preferred to join clubs in their work and public centers while the old age group of 60s, 88.9%, definitely prefered to join clubs in public centers. (e) In the joining sports clubs, married women in 30s will was highest, while the old age group of 60s and over was lowest. (f) In the last one year, housewife participating in 20s was comparatively lower. (g) In the satisfaction of leisure time, the old age group of 60s and over was highest while the young age group of 20s was lowest. That is, the more ages were highter the more the satisfaction of leisure time was. (h) In the percentage of participating in sports activities in the last one year, the married women who finished only middle school was highest, 95.7%, So the higher educational level is the lower the percentages of that is, (i) In the time required, the higher educational level is, the shorter the time became. (j) In the facilities, many married women who finished university used them in their works or schools, or public centers. (k) In the time of moving to the facilities, there was little difference in educational levels, but the time of married women who finished university was less than others. (l) In the participating in several lectures, the higher educational level was, the higher the percentage was. (m) In the satisfaction of leisure time, the higher educational level was, the lower the percentage was, So I don't think the programs and condition of leisure and sports activities satisfy married women of high educational level. 2. The list of factors which have effected on the satisfaction of leisure time, are as follows ; (a) the attitudes of leisure time or sports activities, (b) the result of leisure time or sports activities(treatment for hypochondria and anxiety) (c) the result of leisure time or sports activities(treatment for shoulder pain and backache, and relief of worries) (d) the time required in a time. (e) confidence of body activities (f) the result of leisure time and sports activities(they got confidence and satisfaction) (g) the frequency of participating in leisure and sports activities in the last one year. (h) the result of leisure time and sports activities(they became to be friendly with and became kind to others) (i) the result of leisure time and sports activities(they became to plan their life-styles actively) (j) health condition. From these lists I could understand the most important factor is the body activity-oriented leisure time activities of married women in cities.

This study seeks to analyze and examine factors which affect and leisure leader's organizational behavior. The data for this study were collected at nine sports and leisure training institutes in Busan. At these sites 890 questionaires were distributed to a random sample of sport and leisure leaders. Of these, 849 were used for this study. The results were as follows. 1. Generally all background variables(sex, accupation, age, working conditions and experience of turnover) were related to work-related variables. Education, however, was not so related. Among background variables and organization-related variables, age, marital status and experience of turnover were related to level of pay, organizational commitment and institutional security. 2. The greater the satisfaction with job, working conditions and position, the less the turnover. In the organization-related variables, all variables (level of pay, coworker relations, organizational commitment and institutional security level) had a significant impact on turnover. 3. Work-related variables, organization-related variables, and nonwork- related variables had an impact on turnover intent in all sport categories: taekwondo (42.08%), swimming (32.09%), body-building (30.79%), bowling (29.96%) and golf (27.18%). Also, these variables displayed a significant impact on turnover attempt in all sports categories, except for taekwondo.
