This study aims to empirically analyze the differences between groups of customers who prefer delivery food, which is rapidly growing amid the COVID-19 pandemic, and those who prefer the traditional practice of visiting offline restaurants. Based on the eating out lifestyle, participants were divided into three groups: participants who prefer food delivery, those who prefer to visit restaurants, and those who favor both. The comparison of differences between the groups was analyzed. A total of 215 questionnaires were distributed, and reliability and validity were verified with a sample of 201 copies, excluding 14 unreliable respondents. Then, a multivariate analysis of variance was used to compare the groups. The results showed that regarding offline restaurants, the group of customers who prefer to visit restaurants valued their atmosphere, while the customers who prefer delivery food valued the reputation of the restaurant. Regarding delivery-specialized restaurants, the group of customers who prefer delivery placed greater value on coupon events and payment convenience than other groups. The results revealed that the difference between the customers who prefer to visit restaurants and those who prefer delivery food was identified through empirical analysis, which provides strategic implications for catering companies and restaurant industries during COVID-19 in Korea.

One group pretest-posttest design was used to evaluate the program effectiveness. Anthropometric measurements and measurements on nutrition knowledge, eating attitudes and eating behavior were done before and after education. Data were analyzed using paired t-test, t-test and ${\chi}^2-test$. After completing nutrition education, body mass index (from 19.3 to 18.9), fat mass (from 10.9 kg to 10.1 kg), percent body fat (from 25% to 23.3%) of subjects decreased significantly (p < 0.001). Percentages of overweight or obese children were 24.6% at pretest and decreased to 20.3% at posttest, although it did not reach statistical significance. Total score of nutrition knowledge increased significantly from 11.9 (59.5/100) at pretest to 14.7 (73.5/100) at posttest (p < 0.001). After nutrition education, percentages of correct answers increased significantly in 10 knowledge items out of 20 items. These included items such as desirable weight control, energy requirements for boys, food groups, snack, and function of fat and balanced meals (p < 0.001). Total score of eating attitudes increased significantly from 35.1 to 36.9 (p < 0.001). Attitude of applying nutrition knowledge to daily life (p < 0.001), interest toward nutrition and health (p < 0.001), attitude of moderating food intake (p < 0.01), and attitude toward eating habit and future health (p < 0.05) were significantly different between pretest and posttest. Total score of eating behaviors increased significantly from 46.7 (possible score: 20-60) to 49.5 by nutrition education (p < 0.001). Improvement in eight eating behaviors were noticed after nutrition education. These included eating meals slowly, eat protein foods (p < 0.001), eating breakfast, eating meals regularly, eating meals with diverse foods, having dairy foods, eating foods using plant oils (p < 0.01), and having grains (p < 0.05). Subjects evaluated quite positively in attractiveness of program, understanding of program contents, helpfulness of program in improving nutrition knowledge and meal management.

To investigate effects of the shared living on nutrient intakes,250 college male students who were living alone (104 men) or sharing accommodation with friends (134 men) were participated. Their average age was 22.6 years, their average height was 171.8 cm, their average weight was 65.6 kg and their average Body Mass Index (BMI) was 22.2. The caloric intakes of the men living alone or sharing accommodation were 55.9% and 72.5% of the Korean Recommended Dietary Allowance (RDA), respectively. The decreased caloric level of the group living alone seemed to be due to their decreased protein and fat consumption as compared to that of the group sharing accommodation. The group living alone consumed increased amounts of fiber for breakfast and half the carbohydrates, but more fat (p < 0.05) in snacks than the group sharing accommodation. The daily carbohydrate : protein : fat (C : P : F) ratio averaged 58.6 14.1 27.3, which is a lower carbohydrate and a higher fat ratio than the Korean recommended ratio. However, the group living alone was closer to the Korean recommended ratio than the group sharing accommodation. The food intake habits were evaluated as being poorer in the group living alone as compared to the group sharing accommodation, less frequent consumption of fried / pan-fried dishes, and fruits / juices, but more frequent consumption of instant / processed foods. In comparing the eating patterns of the two groups, the group living alone showed better eating habits, such as more“breakfast eating”and less“snacking in the morning, afternoon or late at night”whereas the group sharing accommodation showed better eating habits such as less“picky eaters”and less “eating out”. In the group living alone, their lower caloric intake was assumably due to their fewer side dishes, however they showed higher eating frequencies of instant i processed foods. Since the lifestyle of living alone seems to grow gradually among young men, we strongly recommend dietary education for them.

This study investigates differences in middle school male students' anthropometric variables and dietary habits using BMI (Body Mass Index) classifications. $\chi^2$ -test for frequency and ANOVA test for mean value and duncan value were used to analyze results. Averaged results of three groups of middle school male students' anthropometry including height (normal group 164.4 cm, overweight group 165.0 cm, obese group 167.0 cm), weight (normal group 56.0 kg, overweight group 70.0 kg, obese group 83.2 kg) and waist circumference (normal group 20.7 cm, overweight group 79.8 cm, overweight group 89.6 cm) were resulted. Classification of obese group was based upon 2007 growth charts using BMI criteria. This study indicates the normal weight group boys have over-eating related dietary habits and the obese groups have less calorie dietary habits. They answered oppositely to normal recognition. The obese group reflected dietary problems, such as preferences for sweet fruit rather than normal group males. Dinnertime of the groups were significantly different and obese group's earlier dinnertime can influence on their late night snack eating. Forty precent of obese male group like fruits as late night eating food. Three meal amount of three groups were significantly different, as obese group answered they ate same amount at every meal. It can mean obese group ate more amount of food in every meal. Overweight and obese male students have dietary problem of fast eating and answers of unbalanced eating were higher in normal group. These could mean obese group eats well in every food and fast eating habit could lead a lot of food eating habit. Obese group chooses out-going food of less calorie and frequency of fast food eating was lower than normal group. In result, obese group answered that they have less calorie related dietary habits, it could mean their answers were false or fixed dietary habit. Therefore, more researches should be followed.

This study was carried out to compare the nutrition knowledge, nutrition attitudes and eating behaviors of dietitians and non-dietitians. The subjects of this study were 148 dietitians and 195 non-dietitians who are working in the metropolitan area. The general characteristics, nutrition knowledge, nutrition attitudes and eating behaviors of the subjects were surveyed using a self-administered questionnaire. The results were as follows: The result of anthropometric data and body mass index showed no significant differences between dietitians and non-dietitians groups. The dietitian group ($16.61{\pm}1.82$) showed a significant difference (p < 0.001) compared to the non-dietitian group ($14.60{\pm}2.17$) in nutrition knowledge scores. Nutrition attitudes of the dietitian group ($36.66{\pm}6.91$) was a little higher than the non-dietitian group ($36.21{\pm}7.95$), but not a significant difference. The dietitian group ($61.52{\pm}9.37$) and the non-dietitian group ($62.50{\pm}11.25$) were no significant difference in eating behaviors. The correlation between nutrition knowledge scores and nutrition attitudes score of dietitians and non-dietitians groups were no significantly difference and also the correlation between nutrition knowledge scores and eating behaviors scores were not statistically significance. Whereas, the correlation between nutrition attitudes and eating behaviors showed a significant difference (dietitian r = 0.40829, non-dietitian r = 0.51914). From these results, we could see the necessity of emphasis of nutrition knowledge by mending the education is necessary to enable dietitians to apply that in real life. Also it is important to guide non-dietitians to adjust their nutrition knowledge, nutrition attitudes and eating behaviors.
