In order to investigate the eating out behavior of university students, this survey was conducted using the questionaires for 710 students(369 male, 341 female) from 11 universities in Seoul. It was revealed that 39.4% of the subjects spent $60,000{\sim}100,000$ won for monthly eating out cost and 57.8% of them ate out more than once a day. Most of them expended less than 3,500 won for lunch, while 36.5% of them spent $4,000 {\sim}5,000$ won for dinner. Dinner was regarded more important than lunch. Korean foods were the most preferred menu for eating out with friends and fast foods were the second. But Boonsik(snack bar foods), Chinese foods and Japanease foods were rarely selected. Frequency of selecting fast foods was 8 times greater than that of Boonsik. This indicates that the preference of western flavor and the pursuit of convenience is getting more obvious. While dating, western foods were preferred, followed by Korean foods, fast foods. The 80 kinds of foods were reported as favored eating out foods. Although 50 among 80 were Korean foods, the rest of them were Koreanized foreign foods most of those were western style. This may suggest that when the students become adults, they will be much fond of western dish for their dinning out. This tendency of preferring western flavor were much apparent in foods for dinner compared with lunch. In both sexes, the standard of food choice was in the order of taste, price, mood, hygiene, service and brand name. But male students were more conscious of price and service while female students were more concerned about taste and hygiene. Most unsatisfying feature in restaurant was unstable atmosphere for both sexes. Taste was the most important sensory factor in selecting the foods, followed by appearance, smell and texture. Major source of restaurant information was recommendation by friends or relatives. But the use of internet or magazine was negligible. Female students had more positive attitude, compared with male students, in using restaurant information and pursuing eating out for gourmet. The dining out menu of which price ranges about $3,000{\sim}5,000$ won could be preferable foods for most people. Therefore, instead of blaming them for eating too much fast foods, new menus which fit the food preference and affordability of the students should be developed.

The purpose of this study was to investigate food safety awareness, knowledge, and behavior in college students, to provide basic data for the increase in food safety awareness. Data were collected from 252 college students in Gyeonggi region, using a self-administered questionnaire. In results of concern about food safety, subjects responded 3.48 of 5.00 and have knowledge about food safety education revealing significantly higher awareness and concern than subjects without knowledge about food safety education. Food safety awareness of distributed food was 2.55, considered unsafe. Among reasons in perceiving food as unsafe, 62.3% of subjects expressed distrust about safety relative food production. As for risk factors relative to food safety, subjects responded that the highest risk factor was food additives (2.35), followed by heavy metal (2.38) and endocrine disrupters (2.38). Correlation analysis resulting in risk factors for food had positive correlation with each other, heavy metal revealed highest correlation with pesticide residue (r = 0.674), than with endocrine disrupters (r = 0.672). Also, genetically modified food revealed high correlation with radiation irradiated food. Regression analysis demonstrated that concern about food safety significantly influenced pro-actively engaging in food safety education. Meanwhile, 63.5% of subjects correctly responded to food safety knowledge items. The item 'the heavy metals are contaminated the most, in the roots of vegetables' revealed the lowest correct answer rate (38.1%). In food safety behavior, the item 'always wash hands before handling food and meal's revealed 3.85, and subjects with awareness and concern about food safety education, responded in significantly higher numbers than subject without awareness and concern about food safety. The most neglected concern was relative to frozen food thawed at room temperature. Together, students recognize that distributed foods are unsafe, and students with awareness and concern about food safety education showed higher knowledge compared to without awareness and concern experience about food safety eduction. So, systematic education using accurate and objective data is required to reduce anxiety and raise the level of awareness and concern about food safety.

Objectives: The study was performed to investigate the relationship between snack intake and oral health behavior in middle school students in Gyeonggi-do area. Methods: The survey questionnaire was recorded by middle school students from July 6 to August 24, 2011. The questionnaire included items on general characteristics, snack intake status, and oral health behavior. Among collected survey questionnaire, a total of 620 questionnaires (320 males and 300 females) were analyzed using SPSS 15.0 program. Results: Frequencies of snack and beverage intakes were significantly higher in males than in females (p < 0.001). Oral health behavior was significantly higher in students with lower snack intake compared to those with higher or average snack intake (p < 0.05). Oral health behavior for tooth brushing and toothbrush care were significantly higher in females than in males (p < 0.05). Conclusions: Oral health behavior score that reflected better oral health of the subjects were higher as the snack intake was lower. Oral health behavior score was higher in females than in males. We conclude that the contents for oral health and nutrition education focused on snack intake need to be developed to induce changes in oral health behavior in middle school students.

Objectives: The purpose of this study was to investigate the correlation between soft drink consumption and subjective oral symptoms in Korean adolescents. Methods: Data of 65,528 adolescents were derived from the twelfth Korea youth risk behavior web-based survey, which was conducted from 1st June 2016 to 30th June 2016. Sociodemographic factors, dietary habit, and oral health behavior were collected as independent variables. The subjective oral symptoms were used as a dependent variable. The chi-square test and logistic regression analysis were performed to identify the correlation between dental caries and the other variables. Results: A multiple logistic regression analysis revealed that subjective oral symptoms were correlated with sex, age, subjective economic status, soft drink consumption, sweet drink consumption, tooth brushing frequency and dental sealant experience. Conclusions: Since the intake of soft drink adversely effects subjectively perceived oral symptoms in Korean adolescents, oral health education should include information on the pH levels of food and beverages including carbonated drinks, the effects of sugar on the teeth, and precautions to preventing tooth damage.

Objectives: The purpose of the study was to investigate the effect of gender in the association between the oral symptoms experience and health behavior. Methods: The subjects were 54,219 adolescents selected from the web-based survey of the 11th (2015) Korean Youth Risk Behavior of Korean Center for Disease Control. Data were analyzed using SPSS 18.0. The subjects consisted of 27,198 male students(50.2%) and 27,021 female students(49.8%) from 400 middle schools and 400 high schools. Results: Multiple logistic regression analysis after adjustment to demographic characteristics and oral health behavior showed experience with drinking and smoking in adolescents increased oral symptoms experienced by both male and female students (OR = 1.3, 95% CI = 1.20-1.34 / OR =1.3, 95% CI = 1.18-1.33), (OR = 1.3, 95% CI = 1.24-1.40 / OR = 1.4, 95% CI = 1.43-1.30). But the difference was not significant between genders. In terms of diet, consumption of carbonated beverages, snacks and fast food saw an increase in oral symptoms experience both gender compared with those whose "No(weekly)" in particular to women, alternatively vegetable, fruit consumption(weekly) were having less intake adolescents increase oral symptoms experience than "time daily(weekly)" intake adolescents both boy and girl especially to girl. Conclusions: There was a correlation between oral symptom experiences and health behaviors. There was also slight differences between genders, with more effect shown on female students. Based on this study, proper and systematic education of oral health management should be carried out at schools.

The paper investigates the antecedents of Organic Food (OF) produce in Vietnam and the intentions and behavior of OF purchasers. A theoretical framework is developed and evaluated by simulation of the structural model. Data was collected from a convenient sample of 222 consumers from Ho Chi Minh City in Vietnam. The selection included 159 (72%) women, who were identified as being the primary buyers of organic food for their family (73%). Findings suggest food hygiene issues and conscientious self-identity as the much beneficial determinants of organic production perceptions. Because of the results in this report, the consideration for food security has gained little research consideration throughout the field of organic produce. Food safety concerns are also related to academics exploring consumer confidence as they might be regarded as one of their aspects in selecting standard, natural or health food products. Findings suggest food security as one of the essential determinants of motivation, while health awareness purports to become the least significant motivation, contrary to observations from certain previous studies. However, it is observed that moral personality-identity influences both perceptions and willingness to buy organic food, stressing that the association of participants with ethical concerns influences their perceptions and eventual choices of consumption.

Coronavirus disease-2019 (COVID-19) has led to a decline in restaurant visits, which in turn has changed the decision-making process of consumers. This study aimed to investigate the factors influencing visit intention during the COVID-19 endemic by employing the expanded theory of planned behavior. A total of 291 samples were collected through an online survey for the analysis. Confirmatory factor analysis, correlation analysis, and structural equation path analysis were performed on the collected data using the Analysis of Moment Structures (AMOS) statistical program. The findings of the study revealed the positive effects of attitude and perceived behavioral control and the negative effects of subjective norms on desire. Second, desire played a mediating role between antecedent variables (attitude, subjective norm, perceived behavioral control) and the visit intention. These findings are meaningful in that they expand the theory of planned behavior during the COVID-19 endemic based on factors that affect visit intention.

As a link in the studies on the extracellular polysaccharide by lactic acid bacteria, the experiment was conducted to investigate the viscosity variations and rheological properties of 10% reconstituted skim milk and 12% reconstituted whole milk, respectively. 1. 10% reconstituted skim milk cultured by Str. thrennophilus 510 showed strong flow property of pseudoplastic fluid depending upon the production of exopolysaccharide. And the viscosity reached the highest value within 14% concentration. 2. 12% reconstituted whole milk cultured by lactic acid bacteria indicated flow property of pseudoplastic fluid. But there was a big difference in the viscosity as compared with 10% skim milk. 3. The maximum consistency index (k) and the minimum flow behavior index (n) of the fermented milk by Str. thermophilus 510 were 43 and 0.09, respectively. They were 35 and 0.09, in case of Lb. bulgaricus.

This study was conducted to evaluated dental health promotion behavior and dental health belief of dental hygiene students in Gwangju and Chunnam. The results of this study were as follow: (1) Higher perceived susceptibility was more decreased grade(p<0.001) and more decreased economic level(p<0.05), more perceived dental healthy(p<0.001). Higher perceived benefit was more increased grade(p<0.001), at perceived health was very unhealth(p<0.05), at perceived dental health was very unhealth(p<0.05), in case of dental office visit before 1 year was highier(p<0.01). Higher perceived seriousiness was at middle economic level(0.01), more increased perceived unhealth status(p<0.05) and perceived unhealthy dental status(p<0.01). Higher perceived salience was more increased grade(p<0.001), in case of dental office visit before 1 year was highier(p<0.001). Higher perceived barrier was more increased grade(p<0.001), more increased economic level(p<0.05), at perceived health was very unhealth(p<0.01). (2) Higher dental health promotion behavior was more increase grade in preventive dental utilization and user dental health recomended device and selection eating case of healthful food to dental health and selection uneating case of harmful food to dental health(p<0.05). (3) performance in dental health promotion behavior was significantly correlated with perceived susceptibility(r=-0.081), perceived benefit (r=0.133), perceived seriousiness(r=0.210), perceived salience(r=0.187).
