  • The purpose of the study was to develop a Web site for the middle-aged women and test the usability of the site. Users' need for information were identified via online survey of 189 middle-aged women. It was found that they had various health problems but very few did any health prevention or health promotion activities. A web site for the middle-aged women was developed based on the result of needs assessment. The site includes content on exercise, diet including weight control, osteoporosis, climacteric, aging, breast and cervical cancer. Besides this health information, FAQ on women's health, my health knowledge test, statistics, link to related institutes and web sites, newspaper articles/mass media clips, journal articles, conferences, papers and other educational information were added. The site was developed as a subsystem of the Healthguide(http://healthguide.kihasa.re.kr). As a way of utilizing the homepage, twenty two women aged 40-50 were recruited at a community-based gathering and health promotion education program was conducted. To test the effectiveness of the education, knowledge, attitude and behavior changes of before and after education were compared. There were significant differences of knowledge and behavior in breast cancer, cervical cancer, osteoporosis, menopause and sexual life. It is expected that Web-based women's health information will contribute to women's health promotion and provide an effective learning media for health education.

  • The purpose of this study was to provide the basic data for developing a program for effective education about GDM(Gestational Diabetes Mellitus) by investigating the knowledge and learning needs of pregnant women about GDM. The subjects were 192 pregnant women who visited obstetrical clinics for prenatal care. The data were collected from October, 1998 to December, 1999, using a 50-item questionnaire(knowledge ; 30 items, learning needs ; 20 items), and analyzed by SAS program for t-test, ANOVA, Ducan test, and Pearson correlation coefficients. The results were as follows. 1. The knowledge level about GDM 1) Pregnant women had very little knowledge(total means ; 15.1 of 30.0) about GDM. 2) Pregnant women more than 30 years old, pregnant women from Seoul, and pregnant women who had more than a bachelor's degree were more knowledgeable about GDM. 3) Pregnant women who didn't experience spontaneous abortions, pregnant women who had DM(Diabetes Mellitus) patients in their families, and pregnant women who received education about DM were more knowledgeable about GDM. 4) Pregnant women knew very well that GDM women have more maternal and fetal complications than normal pregnant women. Although they were knowledgeable about the importance and ways of controlling blood glucose level, they knew very little about the causes, symptoms, or management of hypoglycemia. 2. The learning needs about GDM 1) Pregnant women had high learning needs (total means ; 85.0 of 100.0) about GDM. 2) The learning needs of pregnant women who had more than a bachelor's degree and pregnant women who earned less than two million won in monthly income were higher than that of other groups. 3) Pregnant women had high learning needs about the health of their baby and themselves, but their learning needs related to weight control and exercise-things that play important roles in controlling blood glucose level-were relatively low. As a result of the above findings, a systemic and individualized program is required for pregnant women and GDM patients, In addition to that, further studies that investigate the effects of education and retention of learning obtained by education are required in the near future.

  • Childhood obesity has rapidly increased worldwide and is one of the most serious health problems in this age group. In order to prevent and manage childhood obesity, we developed a nutrition education website. The website consisted of three parts. The first part was made for self-assessment with regard to obesity index, dietary habits, food frequency, dietary attitude, nutrition knowledge, nutrient intake, energy expenditure, and the stage of behavioral change, and tailored messages and advice according to the assessment results. A total of 612 real-size food photos as well as a nutrient database of 3,346 foods and 541 dishes were created to help children estimate nutrient intakes accurately. In addition, an energy expenditure database of 156 activities for children was established to calculate calorie consumption. The second part was made for setting long-term and short-term goals and keeping track of the changes in energy intake and expenditure in one's own page. The third part was made for education. Various types of nutrition information were provided; texts, pictures, calculators and games. The readability and design of the website were evaluated by 46 obese children. Usefulness, design and readability of the website were found to be desirable for children. This website is expected to be used by an obese child alone or with parents or nutrition teachers in order to control body weight through healthy dietary habits and physical activities. In addition, a non-obese child can also use this website for maintaining healthy dietary habits and preventing obesity.

  • Corn silk (Okmi-su) was anciently adopted as a material for tea or beverage. Corn silk extracts (CSE) contain bioactive phytochemicals such as phenolic acid, flavonoids, ascorbic acid, tannins, and glycosides. Under the impact of these functional components, CSE has benefits for antioxidation, diuresis, anti-diabetes, and dyslipidemia recovery. Nonetheless, its role in whole-body adiposity was not investigated; therefore, the effects of CSE on obesity were evaluated in high-fat diet-induced obese mice. Mice were assigned to either group (n=12); 1) normal diet (18% kcal from fat), 2) high-fat diet (45% kcal from fat, the control), 3) high-fat diet with CSE (800 mg/kg diet), and 4) high-fat diet with orlistat (500 mg/kg diet, a comparable control for weight loss). Our results showed that body weight, adiposity, and energy expenditure in obese mice were not altered by CSE. Lean body mass tended to decrease by CSE, which can be explained by stimulation of diuresis (p=0.06). In conclusion, our results suggest that dietary consumption of CSE does not influence the adiposity and underlying substrate utilization in high-fat diet-induced obese mice.

  • Appearance has become an important means of expressing oneself in modern society, and women often desire to lose weight. Therefore, this study examined the diets of female college students with high weight loss needs and analyzed the effects of their body image, sociocultural attitude, body stress and diet behavior on intake weight loss products. Data were collected from 220 Korean female college students from June to July using an online survey program. The questionnaires included body image scale, Sociocultural Attitude Towards Appearance Questionnaire (SATAQ), Body Attitudes Questionnaire (BAQ) and diet behaviors scale. Data were analyzed by descriptive statistics, the $x^2$-test, Pearson's correlation coefficients, and logistic regression analysis using the SPSS 22.0 program. There were significant differences in body image, SATAQ, obesity stress and diet behavior between groups. All variables were significantly correlated with each other. Factors influencing weight loss products intake by female university students were SATAQ (OR=1.15, CI=1.03-1.29), obesity stress (OR=1.13, CI=1.06-1.20), diet behaviors (OR=1.21, CI=1.10-1.33), and knowledge regarding the side effects of weight loss products (OR=3.86, CI=1.62-9.20). Thus, it is necessary to teach female college students to recognize healthy weight control methods. Moreover, if weight loss products are needed, appropriate information should be provided regarding the ingredients and side effects of the product.

  • Research on the hormones of insect has followed by the special opportunities and problems arising from pollution. Since then, the main frame of it has been energetically exploited by ligation, decapitation and so on. In the meanwhile, knowledge of the biochemistry of hormone action as well as other aspects of biochemistry in insects has been gradually disclosed. Since 1966, practical use of active analogs of the hormones has been also worked out as an insecticide and brought the features of it to the light. On the other hand, it is expected to afford the increase of silk productivity resulted from control of the fifth larval period by delaying normal development. With these regards, some of analogs have been tried to apply practically to the silkworm. One of them is "Manta" produced by Zoecon Chemical Company and it is presently used for the increase of silk productivity in Japan. Another one is "R-20458", not registered one, issued by Stuffer Chemical Company. It is still pending for the silkworm growth regulator For the possibility of practical use, two chemicals are tested on the increase of silk productivity by topical application and the obtained results are summarized as follows. 1. It is evident that the fifth larval period was extended by topical application of the tested chemicals "Manta"and "R-20458"at the fifth instar after 51 hours of the last ecdysis, ranging from 12 hours to one day, as compared to. the control 2. In survival rates, there is no significance at 5% level between control and treatments. It proved that there was no toxity to silkworm by topical aprication. 3. There is an increase of cocoon yield in both chemical treatments. It was resulted from increase of weight of single cocoon. "Manta"2.5ppm produced 22.2kg of cocoon. It is equal to 9% increase in index, as compared to that of control. In case of R-20458, the increasing rates were varied at the different concentration; 21.4kg of cocoon production with 5% increase at 5ppm, 20.9kg of it with 2% increase at 2.5ppm and 20.6kg of it with 1% increase at 1. 25ppm in index, respectively, as compared with that of control. 4. Percentage of cocoon shell was increased by topical application. In case of "Manta" 2.5ppm, it is 25.6% which is equal to 6% increase in index, as compared with that of control. For "R-20458", the increasing rates of percentage of cocoon shell were varied with the different level of chemical concentration. They are 25.0% of 4% increase at 2.5ppm, 24.9% of 3% increase at 1.25ppm and 24.7% of 3% increase at 5ppm. 15% increase was attained at "Manta" 2.5ppm in the weight of cocoon layer based on cocoon yield and percentage of cocoon shell in index, as compared with that of control. The rates for "R-20458"are 5% increase at 2.5ppm and 4% increase at 1. 25ppm in index.

  • This study was conducted to compare the dietary characteristics of middle-aged people with different obesity index or food habits. Questionnaires were collected from 480 subjects in Daejon. The data were analyzed by $X^2$-test and ANOVA. The subjects were distributed into the normal weight group(66.3%), overweight group(18.3%) and underweight(15.4%) based on BMI. Twenty-five percent of males and 23.0% of females in the 50's belonged to the overweight group. The least consumed food was milk or milk products among the five basic food groups. The frequency of exercise was low in their daily life. The had better food habits than the males. The overweight group had worse food habits than the normal weight or underweight group. The underweight group ate light meal and ate slowly. The better the subjects had, the more regularly they took breakfast(p<0.001). The good food habits group were more interested in their dietary life and were more careful in selecting foods for their health than the bad food habits group(p<0.001). Based on the results of this study, the practical education programs should be focused on more intake of milk or products and on daily exercise for the self-health maintenance of middle-aged people. Also, proper education programs should be developed for males and females in their 50's to practice weight control and regularity of meals in their life, and to utilize nutrition knowledge in dietary life. Further research on the comparision of dietary characteristics are needed with consideration of the subjects ratio according to BMI.
