The purpose of this study was to investigate the nutritional status of antioxidant vitamins in relation to serum malondialdehye(MDA) level in postmenopausal women with common occurance of cardiovascular disease(CVD). Data about general characteristics including smoking, drinking and exercise status, dietary intake and serum level of antioxidant vitamins, and serum MDA level were collected from eighty-five postmenopausal women. Mean serum MDA level was 1.62$\pm$0.03nmol/ml, and general characteristics and serum lipid profiles were not significantly different among the three group: low MDA(<1.45nmol/ml), midium MDA(1.45-1.74nmol/ml) and high MDA($\geq$1.74nmol/ml). Total mean vitamin A intake was 472.8$\pm$37.7RE, 68% of RDA, vitamin C intake was 134.3$\pm$8.7mg, 192% of RDA and vitamin E intake was 8.6$\pm$0.5mg, 86% of RDA for Korean. In takes of antioxidant vitamins from the diet were not significantly different among the three groups. However significant negative correlation(r=-0.242, p<0.05) was observed between vitamin E intake and serum MDA level in total subjects. Total mean serum vitamin A, $\beta$-carotene and vitamin C level were 0.59$\pm$0.01$\mu\textrm{g}$/ml, 0.25$\pm$0.01$\mu\textrm{g}$/ml and 9.02$\pm$0.28$\mu\textrm{g}$/ml, respectively. Total mean serum vitamin E and vitamin E/total cholesterol level were 9.15$\pm$0.42$\mu\textrm{g}$/ml and 4.09$\pm$0.17$\mu\textrm{g}$/mg, respectively. Serum antioxidant vitamins levels were not significantly different among the three groups. However serum vitamin C and E level were negatively correlated to serum MDA level. We can conclude that it will be helpful for postmenopausal women with common occurance of CVD to improve nutritional status of antioxidant vitamins by increasing intakes of antioxidant vitamins, especially vitamin C and E.

This study was undertaken to examine the degree of knowledge and compliance of breast self-examination with women. The subjects for this study were 474 women aged 35-65 receiving health examination from Yonsu-ku Public Health Service Center in Inchon. Data collection was conducted through the use of 2 questionnaires. Analysis of the data was done by used of descriptive statistics, t-test, ANOVA, and Pearson Product Moment Correlation Coefficient. The results of this study were as follows: 1. There were significant differences in the breast self-examination compliance rate according to age(F=5.82, p=.000), marital status(F=2.67, p=.047), educational level (F=5.83, p=.000) and household income (F=3.41, p=.018). 2. The correct answer rate for each items of breast self-examination knowledge scale was between 14.1% of a minimum rate and 65.0% for a maximum rate of 100. The degree of knowledge for relation of breast cancer and menopause, the time of the highest occurance of breast cancer, the best time of breast self-examination and inspection methods of breast self-examination shows relatively low understanding. 3. The average score of breast self-examination was 1.34 from a maximum score of 6. The score of breast self-examination with palpation methods was higher than with inspection methods. 4. A positive correlation was found between breast self-examination knowledge and compliance rate (r=.417, p=.001). According to the results, it is necessary to provide knowledge of the relationship of breast cancer and menopause, the time of the highest occurance of breast cancer, and the best time of breast self-examination and inspection methods of breast self-examination. Also, it is necessary to provide detail guidance for inspection methods and develop a program for promoting the compliance of breast self-examination.

Introduction: The surgical treatment of Graves' disease has several advantage such as rapid and long lasting therapeutic effect, relatively low incidence of postoperative hypothyroidism and recurrence. Because of less frequent but serious postoperative complications, the operation have not been casually used for treatment of Graves' disease. Hypoclacemia, hoarseness and hematomas are common complications after operative treatment. However, the causative mechanisms of these complications have not been well explained. Objective: We aimed to analyze the risk factors affecting the occurance of complications in surgical treatment for Graves' disease and to evaluate what are the causative mechanisms of postoperative complications. Patients and Methods: From January 1985 to December 1998, a total of 668 surgically treated patients for Graves' disease were enrolled in this study. The incidence of postoperative complications were analyzed in relation to types of surgery, preoperaive preparation, specimen weight, bleeding amount and remnant weight. Results: Postoperative complication was developed in 108(16.2%) of 668 patients. The most common complication was transient hypocalcemia in 85 cases(12.7%). Other complications were: Hematoma in 9 cases(1.3%), transient hoarseness in 5 cases(0.7%), permanent hypocalcemia in 6 cases(0.9%), permanent hoarseness in 3 case(0.4%). The important etiologic factors affecting the occurance of complications were preoperative preparation, perioperative thyroid weight, and remnant thyroid weight. Since 1993, the incidence of complication was more decreased than that in before. Conclusion: To decrease the incidence of postoperative complications of Graves' disease, the patients should be selected carefully, sufficient preoperative preparation should be achieved, and the operation should be performed by well-experienced surgeons.

The main purpose of this study was to find out variables relevant to self-care activities of physically disabled person. The subjects of this analysis were 1277 person which is between 15~64 years, the data came from the 1985 National Interview Survey on Disabled Person in Korea. For this analysis, Breakdown, Oneway and Discriminant Analysis were used. The finding of the analysis can be summarized as follows: First, the mean of self care activities was 2.57 (SD: 0.69, range: 1-3). The relevance for the self-care activities by several variables is as follows. 1. The relevance for the self-care activities by socioeconomic status is significant at age, education level, occupation of household members variables. Especially, in the case of high age, low education level, the self-care activities are shown low score. 2. The relevance by impairment characteristics is shown high significance at all input variables. When disabled person have double impairment. paralysis, late occurance age, and is due to diseases the self-care activities score is lowered. 3. The relevance by health care services variables. is not shown significant at all input variables. Second, the relevance for social activities by sev-eral variables was conducted by discriminant analysis. The relative importance of social activities discriminant function is 0.344 of eigenvalue. The-canonical correlation between the social activities discriminant function and 9 dummy variables is 0.51, total variance of dummy variables for social activities is shown 26 persent. The self-care activities variable represents the highest contribution of its associated variable to the function (canonical coefficient: -.56). The occurance age, the occupation of household members, the education level variables are shown comparatively high contribution to the function. To sum up, this analysis suggests that the self-care activities variable is the highest contributed to the social activities. In relation to self-care concept, this finding will be useful in rehabilitation nursing care.

The problem of the crack which occures from the reinforced concrete structure could be caused by the complexed factors. When the crack happen, it caused fatal blemish to manage and maintain the structure such as structural problem, licking, spalling, viewing Even though they study and work hard to solve this kind of problem in the world, there are no countermeasure for perfect prevention of crack. After the crack checked out, a method of repair-reinforcement has been studied and operated actively, Generally, occurance of the crack in the concrete structure could be taken as granted, no need to mention the damage from the crack, domestic construction try to hide it rather than repair basically, In many cases the construction amount for repairing the crack has to be made in the construction area and the amount is very expensive. To save the repaing fee, companys repair it under the meeting of their desire. it can be expected for the effection of the construction. For this reason, we compare a new injection method to solve the demerits of the present method, to save and use the merit of the present method.

The fluvial phenomena in the bended natural river course are studied experimentally. Some theoretical and empirical conclusions were derived in prior to this study by some authors but the limitation of applicability of those results are not clearly known because of the sensitibitys of the flow regime in the reach. The main objective of this study is directed to evaluate the mechanism of sedimentation and the cross sectional changes in the equilibrium status. the most governing factor influenced to the cross sectional changes in the bended reach is the occurance of spiral flow. In this study, the streamlines and velocity distributions are checked at given interval by the hydraulic model to find out the place where spiral flow are existing under the various flow magnitudes.

In this study, we developed a fog classification algorithm to classify fog type based on fog generation mechanism. For the analysis period of 1986-2005, 15,748 fog events had been reported from the 40 observational sites in South Korea. Thus, practically, it is almost impossible to individually classify the fog type of the whole fog events occurred in South Korea manually. In this study, the characteristics of fog during the research period were investigated and the fog classification flowchart were developed base on the analysis, and the fog classification algorithm was applied for the classification of fogs occurred at the observational sites. Finally, the classified fog-type and hindcasted fog occurance results obtained from the flowchart were evaluated for verification.
