The present study was performed to evaluate energy and nutrients intakes of stroke patients in Daegu Gyeongbuk region, and to analyze the relative risk of stroke related to the intake levels of energy and nutrients. The case subjects (n=100) were selected from newly diagnosed stroke patients at Kyungpook National University Hospital. The control subjects (n=150) were selected from community residents who did not have stroke history and were sex and age-matched with the case subjects. The survey was conducted by individual interviews by trained dietitians using semiquantitative food frequency questionnaires. The odds ratios were calculated by using unconditional logistic regression. In male subjects, patient group had significantly higher consumption than the control group in mean daily intakes of energy, all energy yielding nutrients, vitamin $B_1$, $B_6$, niacin, folic acid, vitamin E, phosphorus, potassium, zinc and dietary fiber, and also in the ratio of energy intake from protein and fat. In women subjects, the patient group consumed significantly lower intakes than the control group in fat, vitamin C, folic acid, vitamin E, iron, but vice versa in carbohydrate energy ratio. As for men, the increased intakes of energy, protein, carbohydrate vitamin $B_1$, E and niacin, zinc, total fatty acids, monoand poly-unsaturated, n-6 fatty acids significantly raised the relative risk of stroke. As for women, the increased intakes of fat, vitamin A, $B_2$, $B_6$, niacin, vitamin C and E, iron, sodium, potassium, selenium, mono-, poly-unsaturated, n-6 fatty acids, cholesterol, taurine and dietary fiber significantly lowered the relative risk of stroke. The results of the study demonstrated that the effect of several nutrient intake levels, such as niacin, vitamin E and fatty acids, on the relative risk of stroke was inconsistent between sex. The reason for this sex difference needs to be elucidated in a larger scale study.

Purpose : Iron-deficiency anemia remains the most common nutritional deficiency in young infants. This study aimed to survey the actual condition of feeding patterns and weaning diet and to study the association between these factors and the prevalence of anemia in infants aged over 9 months. Methods : We studied 171 infants aged 9-24 months who were hospitalized in the general ward with mild to moderate acute illnesses. The mothers answered a questionnaire about the feeding patterns and the status of the weaning diet of their infants. The infants were divided into three groups: infants who were exclusively breast-fed, those who had been given mixed feeding, and artificial milk feeders. Results : The incidence of anemia was significantly higher in exclusively breast-fed infants (23/68, 33.8%) than in the infants with mixed feeding (11/62, 17.7%) and artificial milk feeders (5/41, 12.1%). The mothers' awareness about the state of their infants󰡑 weaning diet was not related to the presence of anemia in the exclusively breast-fed infants. About 70% of the infants had started the weaning diet before age 6 months in all three groups, without any difference according to feeding patterns. Conclusion : The incidence of anemia was significantly higher in the breast-fed group than in the other infants. Many mothers of breast-fed infants with anemia also believed that their infants were taking sufficient weaning foods. Therefore, further education of the mothers about iron-rich weaning foods and the importance of iron intake during infancy is needed to prevent anemia, especially in breast-fed infants.

This study seeks to analyze various aspects of women's fear of sexual crime committed against them within the Seoul metropolitan subway system, which takes center stage in public transportation today in Korea; that is, among different kinds of fear of crime, women's fear of sexual crime is empirically examined, and it is expected that the results of this study shall serve as an important basis for future policy-making, so that the fear of sexual crime against women in the subway system could be reduced. To the end, this study aims first, to investigate the real picture of women's using the subway and their attire, second, to look into the amount of information on such crime obtained and the level of its awareness, third, to analyze the characteristics of the fear of sexual crime in the subway system, and lastly, to empirically examine the relationship between women's regular women's regular attire/their level of information on such crime obtained and their fear of sexual crime. As a quantitative research method to discover facts, this study utilizes reality-analyztical and technical research methods, and for its final statistical analysis, uses questionnaire answered and returned by 509 women, out of a total of 520 female commuters on the Seoul metropolitan subway system who had originally been requested to participate in the survey. The result of this study demonstrates that the level of women's fear of sexual crime on the subway is relatively high. In detail, the higher their monthly income is, the more fearful women feel on the subway; it has also been found that women living in housing they own or in leased housing on deposits (Jeonse) fear sexual crime on the subway more than those living in the other forms of housing. However, the level of fear has been found to be low for those types of sexual crime judged to be relatively unlikely to be committed. Lastly the result of the relationship between women's regular attire/their level of information on such crime obtained and their fear of sexual crime is relatively high and very effective.

Purpose: The aim of this survey was to analyze the choice of sedative drugs and their side effects during pediatric endoscopic sedation in Korea. We also evaluated doctors, caretakers and patient satisfaction with the procedures. Methods: Between June 2006 and July 2006, a 16-item survey regarding current sedation practices, during one month, was mailed to 28 hospitals in Korea. The results of the survey responses were then analyzed. Results: Endoscopy performed under conscious sedation was reported in 89.0% of the responders and endoscopy under general anesthesia in 0.9% of 465 endoscopic procedures. Endoscopy under conscious sedation was performed in 89.1% for upper gastrointestinal endoscopy (GFS) and 88.1% for lower GFS. Midazolam was used for conscious sedation during the endoscopy in 84.5% of cases and propofol was used in two cases (0.5%). In addition, a bezodiazepine/opioid combination was used iin 84.6% (44 cases) for lower GFS. Patients were monitored with pulse oxymetry, EKG (91.4%) as well as automatic BP (5.1%). Transient hypoxia was the only side effect noted and was treated with supplemental oxygen (4.6%). Flumazenil was used in 2.71% of cases. The choice of sedation was made by the endoscopist (84%). The satisfaction rate for endoscopists was 68%, and for the patients and caretakers was 84% (as reported by the endoscopists). Conclusion: Midazolam was used only for the upper GFS and benzodiazepine/opioid combination was used for the lower GFS in Korea. The rate of satisfaction was relatively high and there were no significant side effects noted during the endoscopy under conscious sedation.

In the past, the design education focused on the technique and skill to satisfy the production and consumption activities of a corporation based on beauty and practicality in the industrial age. Now, it's time to switchover to a life-quality enhancing education by harmonizing and meeting the public's physical and mental needs because design education is a character education which enhances the quality of life by uplifting people's aesthetic sense. This paper has emphasized on the importance of public education of design through the theoretical investigation on social environmental changes caused by the emergence of information society,,education problems, public education, and the necessity of design education. The reason why this study should be done has been suggested by investigating the necessity of this research and bringing up the issue. Furthermore, the current status and problems of public education on design have been analyzed. Then, based on the result, the development direction of design education has been suggested. This study can be concluded as follows: First, the design education should change from its vertical structure to a horizontal one. It should be widely spread to the public, getting off from its privatization for a certain group. Second, designers and the public should correct their way of thinking about design. The ordinary people as well as the designers should cultivate their capability to find and take care of design related issues in their everyday lives. Third, all people should be the subject of design education for the public. As a part of cultural education on the public's aesthetic sense, design education should be reborn as a field of study in which a sound public culture can be developed by the integration of human life and culture, exceeding the limit of school curriculum.

Consumer survey(n=1,343) was carried out to investigate the consumer's perception, purchase behavior and demand on the processed meat products. Most consumers purchased the ham and sausage products once a month (40.73%). Consumers(47.19%) didn’t distinguish between ham and sausage products due to the similarity of meat contents and additives in products. Consumers(72.75%) considered the product label when they purchased whereas 27.25% of consumers were not interested in the product label. Consumers(47.65%) were not satisfied with ham and sausage products because there were too much additives other than meat, there were many similar processed products in kinds and appearance(27.70%) and they could hardly detect meat taste(11.62%). Consumers demanded to produce the ham and sausage products which contain high meat contents(64.04%). Consumers were favored with establishment of the price differential system depending on the quality based on meat contents in the product(83.54%). In conclusion, the establishment of the price differential system depending on quality as well as the quality grading system for processed meat products is needed not only to increase the processed meat market but also increase the pork consumption especially for non-preferred pork portions.

This study was conducted to investigate the elementary school students' consciousness of safety, activities to prevent their accidents and factors causing such accidents. For this aim, a research was conducted from Nov. 19 through Dec. 22, 2007 by means of questionnaires distributed to 800 students enrolled in the 5th and 6th grades of 4 elementary schools in a urban-rural combined city. Out of the questionnaires distributed, 785 were collected and put to analysis by using SPSS 13.0 program to determine t-test, ANOVA, logistic regression, etc. 1. The maximum scores of safety consciousness revealing relatively high level of safety consciousness. There was, however, statistically significant difference by grade, type of residence, school life and academic achievements. In detail, 5th graders featured higher level of safety consciousness and those who live in apartments, lead a pleasant life at school and get better academic scores tended to keep higher level of safety consciousness. 2. The subjects of the high scored of activities to prevent accidents, with a statistically significant difference by gender, grade and individual personality. Females, 5th graders and active students were found to be more conscious of preventive activities for accidents. 3. In general, 6th graders and active students turned out to have experienced more accidents. 4. The main factors exerting influence on occurrence of accidents on the part of elementary school students are known to be preventive actions and consciousness of traffic safety in the category of safety consciousness. The significant variable in preventive actions was preventive actions of traffic accidents, burns and intoxication by category of accidents, but individual personality by category of general characters. Sixth graders and male students experienced more accidents, without significantly significant difference, though. As a result, From the above findings, prevention of safety accidents is found to be very important for elementary school students. It is therefore suggested that schools as well as homes should continue to conduct practical education to prevent accidents with priority placed on familiarizing students with preventive activities in daily life in consideration of their personal characters.

The objective was to know if seed potato farmers in Kangwon alpine area control weeds effectively and use herbicides properly to control weeds. Seed potato farmers in Pyongcbang, Hoengsong, and Kangnung have noxious weeds, such as marsh pepper, lambsquarters, barnyard grass, mugwort, asiatic dayflower, hairy carbgrass, ladysthumb, common chickweed, field horsetail, and common purslain, in their farmyard. These are controlled by a combination of physical and chemical weed control methods. However, several weeds such as marsh pepper, field horsetail and, mugwort are poorly controlled by 2-fold amount of several herbicides, including paraquat, pendimethalin, and metribuzin (58% of the answered). Herbicides are not selected and used in a proper manner by seed potato farmers: most of farmers selected herbicides by their experience (51% of the answered) and dealers recommendation (34% of the answered), while only a few farmers of the answered took advantage of the Farmers Handbook for Herbicide Application. In addition, the selected herbicides, including non-registered ones such as paraquat and fluazifop-butyl, are applying three to five years in a succession. With these improper selection and usage of herbicides, sixty-seven percent of the answered farmers have experienced crop damage and seventy-five percent have poisoning. We conclude that a systemic educational program for the proper selection and use of herbicides is needed for seed potato farmers in Kangwon alpine area.

In this study. we tried to provide basic materials for teachers to develop consumer's guide of internet shopping for middle and high school students through surveying their Purchase realities, clothing purchase behaviors. and clothing purchase attitudes when they use internet shopping mall. The questionaires were distributed to middle and high school students in Seoul, Daegu, Kyunggi, Chungbuk, Chungnam, Kyungbuk, and Kyungnam November, 2004. The followings are the results of this study. First, clothing items which were bought in internet shopping malls were shirts. shoes, pants, bags in order and they were below $20,000\~30,000$ won. Main payment method used was sending money to seller's account. Second, clothing purchase satisfaction degree was comparatively high but the satisfaction degree for the compensation policy was low. If they had any claims for the products. they were likely to behave more actively than passively. Third. returned items were shirts, pants, shoes in order which are the same as purchasing items and they were due to the size and the difference between the products recognised by computer screen and the real products. The $89.0\%$ of the subjects who have purchased clothing through internet expressed high intention to purchase in the future through internet. Forth the degree of attitude toward the internet shopping concerned with clothing purchase was high in the factor of 'convenience of shopping', especially they thought that the purchase through internet had the advantage of varieties and prices. The significant differences were found (1) in the experience of purchase and clothing purchase through internet according to their regions. school years, allowances per month, (2) in the purchased items through internet according to only their sexes, and (3) in the desired Purchase items through internet according to school years, their sexes. regions. The more frequently the middle and high school students use internet, the more goods they purchase through internet, especially the portion of the purchased clothing is getting bigger year by year. This suggests that we need to develope well-organized programs to teach good consumer's attitude to the middle and high school students when they purchase through internet.

Background : The statistical analysis is an essential procedure ensuring that the results of researches are based on evidences rather than opinion. The purpose of this study is to evaluate which statistical techniques are used and whether these statistical methods are used appropriately or not in the journal of Tuberculosis and Respiratory Diseases. Materials and Methods : We reviewed 185 articles reported in the journal of Tuberculosis and Respiratory Diseases in 1999. We evaluated the validity of used statistical methods based upon the checklist that was developed on the basis of the guideline for statistical reporting in articles for medical journals by International Committee of Medical Journal Editors. Results : Among 185 articles, original articles and case reports were 110 (59.5%) and 61 (33.0%) respectively. In 112 articles excluding case reports and reviews, statistical techniques were used in 107 articles (95.5%). In 94 articles (83.9%) descriptive and inferential methods were used, while in 13 (11.6%) articles only descriptive methods were used. With the types of inferential statistical techniques, comparison of means was most commonly used (64/94, 68.1%), followed by contingency table (43/94, 45.7%) and correlation or regression (18/94, 19.1%). Among the articles in which descriptive methods were used, 83.2% (89/107) showed inappropriate central tendency and dispersion. In the articles in which inferential methods were used, improper methods were applied in 88.8% (79/89) and the most frequent misuse of statistical methods was inappropriate use of parametric methods (35/89, 39.3%). Only 14 articles (13.1%) were satisfactory in utilization of statistical methodology. Conclusion : Most of the statistical errors found in the journal were misuses of statistical methods related to basic statistics. This study suggests that researchers should be more careful when they describe and apply statistical methods and more extensive statistical refereeing system would be needed.
