This study aimed to compare the dietary habits, nutritional knowledge, and health-related behaviors of students by high school type using questionnaires. The subjects were 586 male students (academic high school students (AS); 294, specialized high school students (SS); 292) in Jinju, Gyeongnam. The frequencies of eating breakfast and snacks were higher in AS than in SS (p<0.05), whereas the frequency of drinking was higher in SS than in AS (p<0.05). The main reason for skipping breakfast was 'poor appetite' in AS (45.2%) and 'lack of time' in SS (56.5%) (p<0.05). Favorite snacks included 'pizza, hamburger' (33.0%) and 'bread, noddle, ramyun' (31.0%) in AS as well as 'pizza, hamburger' (32.5%) and 'fruit, fruit juice' (26.0%) in SS. A mean of 56.2% of students ate an unbalanced diet, and the main reason was 'untasty' (47.2%). The frequency of eating out was higher in SS than in AS (p<0.05), and the main menu while eating out was 'Korean food' in AS (96.3%) and SS (90.3%). The frequency of 'meat, fish, egg, beans' was higher in AS than in SS (p<0.05). On the other hand, the frequencies of 'fruit, fruit juices' (p<0.05), 'milk, milk products' (p<0.01), 'seaweeds' (p<0.05), 'instant foods' (p<0.001) and 'soda and ion drinks' (p<0.001) were higher in SS than in AS. The mean rates of drinking and smoking in students were 84% and 29.5%, respectively. The main reason for drinking and smoking was 'to relieve stress' in AS (38.0%) and SS (30.9%) (p< 0.001). In general, the nutritional knowledge level of SS was higher than that of AS. In conclusion, there were significant differences in the frequencies of eating breakfast, food intake, drinking and reasons for eating snacks, unbalanced diet, drinking and smoking between AS and SS. Therefore, it's necessary to provide proper nutritional education for students according to high school type.

This study was conducted to examine relationships between drinking patterns and metabolic syndrome among Korean adolescents. Statistically weighted data from the Sixth(2013-2015) Korea National Health and Nutrition Examination Survey data were analyzed. Multivariate logistic regression was used to determine relationships between adolescent drinking patterns and metabolic syndrome risk factors with adjustments for individual covariates. A total of 1,698 Korean adolescents (Men=901, Women=797) were identified. Among male adolescents, drinking frequency in the past year was significantly associated with triglyceride level (p for trend=0.03); and men who usually consumed ${\geq}5$ drinks on a typical occasion had a greater risk of high-triglyceride level (adjusted odds ratios: 2.72, 95% confidence intervals: 1.00-7.34, p=0.05). Among female adolescents, drinking frequency in the past year was significantly associated with blood high-density lipoprotein cholesterol level(p for trend=0.01). Drinking frequency and amount were associated with higher triglyceride level among male adolescents, indicating that adolescent drinking may be associated with increased metabolic syndrome development in adulthood. The study results suggest that continuous drinking prevention education and further research for adolescents and metabolic syndrome predictors are needed to prevent development of metabolic syndrome in adulthood.

The Korea Convergence Society. The aim of this study was to evaluate the association between alcohol consumption and periodontal diseases in Korea adults. The date from the 2014 Korean National Health and Nutrition Survey were used, and 4,328 subjects over 30 years were included in the analysis. Periodontal disease was assessed using the Community Periodontal Index. The adjusted odds ratio of drinking experience, drinking frequency, the drinking amount and the drinking duration were calculated from the logistic regression model with the never-drinkers as a reference group and the logistic model controlled for age, gender, education, and diabetes. This study found that the risk of periodontal disease according to the drinking status of adults over 30 years of age was 1.39 times (95% CI=1.01-1.90) higher than that of non-drinking group when the number of drinks consumed at one time was more than seven glasses. The frequency of binge alcohol consumption, amount of alcohol consumption and duration of alcohol consumption were significantly associated with the risk of periodontal disease in a dose-response pattern among over 30 years. Alcohol consumption was discovered to be a potential risk indicator for periodontitis. Dental practitioners need to be aware that patients who drink may be at higher risk of periodontitis and could benefit from advice to quit drinking and maintain regular dental visits.

Objectives: This study intends to understand the difference within group of social support level and the effect of social support to health behaviors and health status of the elderly by selecting the old of local society as target. Methods: Data were obtained from self-administered questionnaire of 8,688 persons, older than 65 years, living in a community. We measured the sociodemographic characteristics, social support(family support, other support, quality of support), physical health state(subjective health status, number of chronic disease), physical function state(activities of daily living; ADL, instrumental activities of daily living; IADL), cognition state(mini-mental state examination-Korean; MMSE-K) and depression state(short form of geriatric depression scale; SGDS), health behaviors(smoking, drinking, exercise, eating habit). Univariate, multinominal logistic regression and covariance structure analysis were employed to analyze factors affecting on the social support of the elderly. Results: When considering the degree of social support by the sociodemographic characteristics of the older adults, the family support, other support and quality of support is better when the old is male, young, high education and self-reported living status is good and it has significance statistically. When considering the relation between social support and health status, the family support, other support and quality of support is better when the old's subjective and objective physical health status is good. The family support, other support and quality of support is better when the old's subjective health status is better. The other support and quality of support is better when the old's ADL(activities of daily living) and IADL(instrumental activities of daily living) are good. The family support, other support and quality of support is better when the old's cognitive function and depression state is better. When considering the relation between social support and health behaviors, in case of smoking and drinking, the quality of support, family support and other support is better when the old smokes and drinks rather than the old does not. In case of exercise and eating habit, the family support, other support and quality of support is better when the old exercises and eats regularly rather than the old does not. It has significance statistically. From the result of performing covariance structure analysis by structural equation modeling(SEM) with two endogenous variable(health behaviors and health status) and one exogenous variable(social support), factor loading of health status is 0.74 and factor loading of health behaviors is 0.05. The social support explains health status of 55.4% and health behaviors of 2.9%. Conclusions: This study has the meaning that it finds the difference of social support generating from inside of the group for the old residing in city and country and specifies the effect that the difference of social support influences to health status and health behaviors. From now on, in the development of health improvement strategy of the olds, it is necessary to approach from inclusive aspect while considering psychosocial factor such as social support and social economical factor as well as health status.

Hydrogen sulfide ($H_2S$) is a by-product of metabolism of amino acids including sulfur and alcoholic fermentation, it is generally thought of in terms of a poisonous gas. Though $H_2S$ can have a negative impact on the perceived quality of fermented drinks due to an undesirable aroma, it plays prominent roles as a neuromodulator in the mammalian brain as well as a smooth muscle relaxant. Nowadays studies on the proteins which produce $H_2S$ are carried out in various fields such as structure, function, and metabolism. Here we propose to develop a simple and rapid $H_2S$ forming assay method, which will lead to speed up preparing the $H_2S$ forming proteins for identification by MALDI-TOF MS analysis. We detected three kinds of proteins which produce $H_2S$ in the crude extract of Saccharomyces cerevisiae. Those proteins were cystathionie $\beta$-synthase, O-acetylserine sulfhydrylase, and cystathionine $\gamma$-lyase.

This study was performed to investigate the correlation between Premenstrual syndrome (PMS) and nutritional intake, blood composition of female students. One hundred and one female students were selected as the experimental subjects at Gyeongsang National University. To assess the PMS symptoms of the subjects, a questionnaire (PAP) score based on the methods of Halbreich, Endicor and Nee was prepared with 34 different items. Dietary survey was conducted by 24­hour recall method for 3 days and nutrient intakes were analyzed by the CAN-Pro. Blood composition of WBC, RBC, Hb, Hct, Ca and Mg was measured. The average height, weight and BMI of subjects were $160.7\pm4.6cm,\;54.1\pm5.7kg\;and\;21.2\pm1.9$, respectively. Average intakes of energy, calcium, iron, zinc, vit $B_2$, and folic acid per day were $1810.2\pm344.9kcal(90.5\%\;of\;RDA),\;621.1\;197.3mg(88.7\%\;of\;RDA),\;15.9\;pm4.9mg\;(99.3\%\;of\;RDA),\;8.1\pm3.4mg(80.5\%\;of\;RDA),\;1.1\pm0.6mg(88.3\%\;of\;RDA)\;and\;234.3\pm78.6{\mu}g(93.7\%\;of\;RDA)$, respectively. Score of the behavioral symptoms, psychologic symptoms, physical symptoms and other symptoms were recorded $1.79\pm0.86,\;2.11\pm1.08,\;2.31\pm1.11\;and\;1.58\pm0.86$, respectively. The relation between PMS and menstrual cramps was significant. A significant difference was observed for menstruation amount in physical symptoms (p<0.05) and other scores (p<0.05). The group who drinks alcohol over 30g per day showed higher scores at total PAP (p<0.05), psychologic symptoms (p<0.05), physical symptoms (p<0.05), and other scores (p<0.05) than those who don't drink alcohol. Calcium in the blood showed a negative correlation with total PAF score (p<0.05), behavioral symptoms (p<0.05), physical symptoms (p<0.05) and other scores (p<0.01). Magnesium in the blood showed a negative correlation with physical symptoms (p<0.05), other score (p<0.05). WBC was negatively associated with psychologic scores (p<0.05). Hb and Hct were negatively associated with other scores (p<0.05). In conclusion, calcium intake showed a level of $88.7\%$ of RDA and this study revealed that there is a correlation between PMS and blood composition in female college students. Therefore, calcium and magnesium supplements can be beneficial to relieve PMS symptoms.

The purpose of this study was to conduct nutrition education using animations for the establishment of proper eating habits among elementary school students and to evaluate its effectiveness. The subjects of this study were two classes of fourth grade students in an elementary school located in Daegu-city. There were 29 students in each class. One class, the "nutrition-education" group, received nutrition education; the other class, the "no-education" group, did not receive the education. After completing the eight nutrition lessons, the effectiveness of the education was analyzed by measuring changes in the nutrition knowledge, eating habits and food preferences of the nutrition-education group vs. the no-education group. Before nutrition education, there was no significant difference between the two groups in terms of nutrition knowledge. However, after the nutrition education, the nutrition-education group's nutrition knowledge was significantly improved, compared to that of the no-education group (p < 0.001). Following education, the nutrition-education group's responses to the "eating habit" item, "I eat fruits every day," were significantly more positive, compared to the responses of the no-education group (p < 0.01). However, for the ten food groups listed as food preferences, except for fish and shellfish (p < 0.05), there was no significant difference in the responses of the two groups. Following the education, the nutrition-education group showed significantly increased preferences for 12 food items (red beans, mackerels, yellow corvinas, dried laver, kelps, radish, lettuce, pears, kiwi fruits, plums, grapes and sweet drinks made from fermented rice) out of 112 items, compared to the selected preferences of the no-education group. After education, 75.9% of the students in the nutrition-education group indicated changes in their eating habits, and 89.6% of them answered that the nutrition education helped them change their eating habits. The most helpful medium for changing their eating habits was animations (31.0%), followed by songs (20.7%) and lectures (17.2%). As a result of this study, after completing the nutrition education, students in the nutrition-education group showed significant changes in food preferences, and their level of nutrition knowledge was significantly increased. However, their eating habits did not actively change. Therefore, in order to establish proper eating habits, a longer period of consistent education is required, using various educational media and learning methods such as extracurricular activities and discretionary activity programs.

This study was conducted to develop a processing procedure for soft drink and wine from purple sweetpotato and to determine the color stability of purple sweetpotato anthocyanin pigment after production. Purple sweet potato soft drink was found to have 15.6% of total extraction, $11.8\;Brix^{\circ}%$ of sugar and pH 4.1, whereas wine had 12.6% of alcohol, $7.8\;Brix^{\circ}%$ of sugar and pH 4.9.Color stabilities of the soft drink and wine showed little difference after four-month storage from the time right after processing. The public found the soft drink that was made from 90% of purple sweet potato, 5% of citron and 5% of honey, more to their taste, rather than other soft drinks that were either made from 100% purplesweet potato or made from 80% of purple sweet potato, 10% of citron and 10% of honey. The public also found $45^{\circ}C$. of fermentation temperature more agreeable than that of $30^{\circ}C$. Powder, vinegar and anthocyanin pigment earned from purple sweet potato showed high stability, as they showed no change in color after four months in storage.

This study was conducted to develop and evaluate food menus after investigating eating behaviors and food preferences of preschool children. Parents of the preschool children In 2 Gumi City day-care centers completed questionnaires in July 2003, which were used to assess eating behaviors and food preferences of their preschool children. Analysis of the questionnaires led to the development of the menus. Menus (n=10) were developed for five different categories (two menus were developed for each category) including general menu, unbalanced menu, anemia menu, obese menu, and traditional menu. The preschool children(n=656) evaluated the menus as they were provided with each them throughout October 2003. The five score scale method was used to evaluate taste, smell, looks, texture and general preference of each menu. Results in eating behaviors showed that 70.7% of preschool children had unbalanced eating behaviors. No gender based differences in eating behaviors were found, but in regard to food preferences boys tended to prefer carbonated drinks more than girls. Results indicated that among all menus, fruit ranked highest $(3.97{\pm}0.65)$ for food preference, and vegetables ranked lowest for food preference $(2.46{\pm}0.68)$. Food preference in regard to cooking process indicated the highest preference was for fried foods $(3.80{\pm}0.68)$ and the lowest preference was for raw vegetables $(2.61{\pm}1.27)$ and namul $(2.85{\pm}1.13)$. Preference for taste ranked the highest $(4.30{\pm}0.91)$ but preference for looks recorded the lowest $(3.95{\pm}0.89)$. Of all the foods in the menus, steamed tofu rated the highest for individual food item preference, while tuna sesame leaf rice rated the lowest preference. Statistical analysis of interrelationships among food taste, smell, looks, texture and general preference were significant (p<0.0l). Results from this study suggest that various factors including food taste, smell, looks, and texture influence the food preferences of preschool children. Therefore, it is concluded that by developing a variety of appetizing menus for use at home and in day-care centers, containing varied food items and cooking methods, preschool children will be encouraged to increase their food preferences and to establish appropriate eating behaviors.

Methods: The samples to achieve the purpose of this research are composed of 386 students in J industrial high school, OO city, Kyounggido, the number of male students 286, and female students 100. Data were statistically analyzed by frequency analysis, cross tabulation by using SPSS WIN Ver. 12.0. Results: First, The answers in terms of oral symptoms were in the order of 31.8% for gum hurt and bleeding, 31.4% for pain in teeth by drinking or eating hot and cold drinks or food, 27.1% for broken or cracked teeth, 25.7% for aching and throbbing teeth, 20.6% for unpleasant mouth smell, and 5.7% for pain of tongue and soft oral tissues. Second, In terms of behavior for oral health, 88.4% answered that they consume cariogenic snacks, while 29.2% of them, 2.5% of male and 6.3% of female enjoy consuming them but hardly brush their teeth after consumption. Third, In terms of timing for brushing teeth, the results show that 50.0% do so before breakfast, 47.9% after breakfast, 15.2% after lunch, 36.9% after dinner, 65.5% before going to sleep, and 3.5% after consuming snacks, whereas 64.2% answered that they are not aware of fluorine mouthwash. Fourth, In terms of oral health condition. proportion of children with one or more caries in permanent teeth was 71.0%, while 51.4% have $2{\sim}3$ cariogenic teeth, and 16.8% have more than 4 cariogenic teeth. Considering sex, female students have somewhat higher ratio showing 68.5% for male and 78.0% for female, but the ratio was 53.1% for male and 46.7% for female in case of $2{\sim}3$ cariogenic teeth, and 17.5% for male and 15.8% for female in case of more than 4 cariogenic teeth. 9.3% of students turned out to have decayed teeth. Fifth, In terms of oral hygiene condition, only 7.9% of them had excellent condition, and 38.4% need to improve. More specifically, 41.1% of male students and 30.6% of female students need to improve their oral hygiene condition. Conclusions: The study results suggest that School Dental health programs increase and need to be community-incorporated and comprehensive from elementary to high school.
