The purpose of this study was to identify the behavioral, attitudinal, and demographic correlates of light, medium, and heavy users of eating out at family restaurants. Among 358 reponses from the subjects, 224 responses were utilized for the analysis, and 134 responses were reserved for validating the discriminant function. Descriptive statistics, reliability analysis, stepwise discriminant analysis, canonical discriminant analysis, and anova analysis were used for this study. The findings from this study were as follows: First, He behavioral characteristics were found to discriminate among the three usage groups. Second, it was found that heavy users expressed greater difference between perception and expectation on the quantity of food that are appropriately served and the consistent quality of food at every visit. Third, the usage rate of eating out was not dependent on the sex, but dependent on the companion, average expenditure, and the time of eating out in chi-square test. Finally, the results of the study provide some insight into the pattern of marketing strategies that can be successfully used by the managers of family restaurants.

Objectives: This study investigated the association between the frequency and pattern of eating alone and the mental health status according to region in Korean adults. Methods: The data of 10,040 Korean adults aged ≥ 19 years from the Korea National Health and Nutrition Examination Survey (KNHANES) 2017 and 2019 were used. Participants were divided into 4 groups based on their frequency of eating alone: none (all meals together), 1, 2, and 3 meals/day alone. The regions were divided into urban and rural areas. Mental health status was assessed by stress recognition, depressive symptoms, and suicidal ideation. Multivariable logistic regressions were conducted to estimate the adjusted odds ratios (AORs) with 95% confidence intervals (CIs) on the association of the frequency and pattern of eating alone with poor mental health after controlling for covariates. Results: Among Korean adults, 74.1% ate more than one meal a day alone. Individuals having 3 meals a day alone tended to be less educated, single, single person households, or living in urban areas (all P < 0.05). In rural areas, those having 3 meals/day alone had higher odds of stress recognition (AOR: 1.55, 95% CI: 1.02-2.35) than those having all meals together. In urban areas, individuals eating alone 3 times/day had higher odds of stress recognition (AOR: 1.60, 95% CI: 1.31-1.96), depressive symptoms (AOR: 1.61, 95% CI: 1.23-2.12), and suicidal ideation (AOR: 2.14, 95% CI: 1.42-3.22) compared to those having all meals together. Urban residents having dinner alone had higher odds of depressive symptoms (AOR: 1.29, 95% CI: 1.05-1.58) and suicidal ideation (AOR: 1.66, 95% CI: 1.19-2.33) than those having dinner with others. Conclusions: Our findings showed that the frequency and patterns of eating alone were differentially associated with increased odds of poor mental health according to region of residence. Nutrition education is needed for those frequently eating alone, particularly those living in urban areas, to highlight the advantages of eating together and to ensure that they have balanced and healthy meals even if they eat alone.

Objective: The present study was carried out to evaluate the effect of high dietary cation and anion difference (DCAD) rations on diurnal variations in eating and meal patterns, water intake and urination patterns in dairy goats fed under high ambient temperature (HTa). Methods: Ten crossbred dairy goats during peri-parturition period were selected and divided into two groups of five animals each. Experimental diets were control DCAD (control, 22.8 mEq/100 g dry matter [DM]) and high DCAD (DCAD, 39.1 mEq/100 g DM). The composition of two diets consisted of 44% corn silage and 56% concentrate. From the 2nd week to 8th week postpartum, goats were fed ad libitum twice daily either with the control or DCAD total mix ration with free access to water. The spontaneous eating and drinking patterns were determined. Results: The environmental conditions in the present experiment indicated that goats were fed under HTa conditions (average peak THI = 85.2) and were in heat stress. In addition to the typical HTa induced tachypnoea in both groups, the respiratory rate in the DCAD group was significantly higher than the control group (p<0.05). Although the goats from both groups showed comparable level of eating, drinking and urination during experiment, the meal pattern and water intake were different. High DCAD apparently increased eating and meal patterns compared with the control. At week 8 postpartum, goats from high DCAD group had significant (p<0.05) bigger meal size and longer meal duration. Moreover, high DCAD appeared to increase night-time water intake (p<0.05). Conclusion: Both meal pattern and night-time drinking effects of DCAD suggested that feeding with high DCAD ration may alleviate the effect of heat stress in dairy goat fed under HTa conditions.

The objective of this research was to explore the influences of 'having a meal with someone' on individuals' eating pattern. Eating is not a simple matter of energy intake but also serves to anchor daily routines being cultivated by people and society. This study was conducted using a cross-sectional eating behavior survey of university students (N = 893, 380 men, 513 women) aged 20 to 24 years. Results were analyzed and presented as frequencies, means and ${\chi}^2$-test with SPSS 14.0. Differences in dietary habits by commensality and solo-eating were observed; Students who ate alone, spent 15 min for a meal and ate convenience food items when they didn't feel hungry. Compared to students who ate alone, those who ate together with someone spent 30 min for a meal and ate more amount of food. Eighty percent of respondents ate more various menus in commensality than solo-eating. They felt lonely when they ate alone and preferred to eat together. In conclusion, university students start to decide and select their own meals by themselves after junior and high school food services which are fixed with regard to menu and the amount. Dietary habits of Koreans rapidly changed concomitant with social changes over the past half century. Governments and health experts recognize that unbalanced meals cause lifestyle-related diseases, in particular obesity. Our research findings will contribute to more comprehensive efficient nutrition education programs in order to prevent obesity and other lifestyle-related diseases in early stages of adulthood.

Rapid shift to western dietary patterns and social drive of thinness would lead to increase the likelihood of developing eating disorders. This study was performed to analyze the associated factors between dietary pattern and self visualization in terms of body shape, which may increase the risk of disturbed eating attitudes among high school students in Korea. A cross-sectional study was conducted from 2009 to 2010 for high school students including both male and female students, from 6 schools in Gyunggi Province, Korea. A total of 766 students self-reported a questionnaire, including weight control practice, perceptions of self body image and ideal body image, dietary habit, and EAT-26 (Eating Attitude Test-26). Logistic regression analysis was used to fine the factors potentially associated with disturbed eating attitudes. Statistical analysis was conducted using SAS program (version 9.1). Results showed that disturbed eating attitudes were found in 8.7% of male high school students, and in 20.8% of female high school students. Experience of body weight control was reported by 56.2% of male students and by 87.3% of female students. According to multiple logistic regression analysis, obesity was independently associated with high risk of disturbed eating attitudes in male students [Odds Ratios (OR) 2.96, 95% Confidence Interval (CI) 0.90-9.71]. Body image dissatisfaction (OR 2.77, 95%CI 1.37-5.62) and extended family type (OR 2.70, 95%CI 1.05-6.90) were independently associated with high risk of disturbed eating attitudes, especially in female students. In conclusion, proper efforts in education for obesity and developing self-esteem to reduce the risks of disturbed eating attitudes should be implemented in high school nutrition program.

This study was undertaken to assess eating habits and food consumption pattern of 365 adolescent girls in Kwangju area. Subjects were divided into 3 groups based on relative body weight as obesity index. Anthropometric data showed that mean height and weight were $161.9{\pm}19.0cm$ and $53.3{\pm}7.2kg$ respectively which are similar to those in the Korean Standard Growth data. Mean BMI and relative body weight were 20.50 and 97.1%. Age of menarche in the subjects significantly influenced the obesity index. Food habit score in the underweight group was significantly lower than that in the normal group at ${\alpha}=0.2$ level by multiple range test. Obesity was significantly associated with more frequent and irregular eating. It seems that students in the obese group were concerned on their body weight and tended to consume much vegetable. Obese group consumed more fruits, less butter and fruit juice compared to other groups. It might be suggested that more effective nutrition program might be developed and implemented to ensure good food habit of adolescent girls including obese as well as underweight group.

Objectives: The purpose of this study was to evaluate the consumption pattern of sugar-sweetened beverages (SSB) and compare body composition changes by SSB consumption based on 28 days of dietary records from a four-week time-restricted eating intervention among young adults in Korea. Methods: A total of 33 participants completed the four-week dietary intervention with 8-hour time-restricted eating (TRE). The body composition was measured by bioelectrical impedance analysis at baseline, and daily dietary records were collected for 28 days during the intervention after 4 weeks. Results: Based on 924 days of dietary records, the average eating occasion of SSB was 0.9 times per day, and the average amount of SSB was 205.8 g/times. Based on an individual's usual intake of 28 days, the average eating frequency of SSB was 16.6 times out of 28 days, and the average amount of SSB was 184.0 g/day. The average energy intake from SSB was 131.0 kcal /day (8.7% of energy), and sugar intake from SSB was 18.2 g/day (4.9% of energy). The sugar intake was 2.6% of energy from sweetened dairy products, followed by 2.0% from coffee drinks, 0.5% from soda and juice and 0.2% from others. When subjects were divided into high (14 days or more) and low (less than 14 days) SSB groups based on eating frequency, the weight change in the low SSB group was -2.0 kg over 4 weeks, which was significantly lower than -0.7 kg in the high SSB group. However, no significant difference was found in muscle mass, fat mass and body fat percent between the two groups. Conclusions: This study suggests that low consumption of sugar-sweetened beverages is more desirable in weight management despite having the dietary intervention of time-restricted eating without counting calories. Thus, further longitudinal studies on the association between SSB and obesity in Korean adults are necessary.

The survey was conducted from Sep. to Oct. 2001 by questionnaires in order to investigate the patterns and preference of eating out of 321 workers men in JinJu. The frequency of eating out was different with the age of subjects and the purpose for which meals were eaten. However the price of a meal was not different with the purpose of eating out except for purchasing foods at lunch or dinner. Even though small group in 30s and 40s over aged, there are some peoples willing to pay for expensive foods for family or friends. So it needs to develop luxury food items which appeal to these target customer groups. Bibimbab(rice with assorted vegetables) and Naengmyun(cold noodle) had higher ranking for a lunch on the 26-list of famous dishes of commercial restaurents in JinJu. Subjects also preferred Hanjungshik(basic type of Korean menu pattern) and Haemultang(sea food casserole) for a dinner. They had preferences Hanjungshik, Sashimi, Beef Bulgogi for business, social, family meetings. They recommended Hanjungshik, Bibimbab, Beef Bulgogi, Jangeogui(grilled eel), Sashimi to foreign tourists for the best JinJu food with pride. Subjects liked Pizza, Hamburger, Soondae(Korean sausage) for a snack in a day and Pizza, Soondae, Yangnyeumtongdak(spicy fried chicken) were preferred for a snack at night.

We examined the evolutionary and ecological processes shaping current geographical distributions of a Korean wood-eating cockroach species, Cryptocercus kyebangensis. Our research aims were to understand evolutionary pattern of DNA sequences, to construct genetic network of Cryptocercus kyebangensis local populations and to understand evolutionary and ecological processes shaping their current geographical distribution patterns via DNA sequence information and genetic networks, using sequence data of two genes (ITS-2 and AT region) from local populations of C. kyebangensis. The results suggest that the ITS-2 and AT region are appropriate molecular markers for elucidating C. kyebangensis geographic patterns at the population level. The MSN-A based on the ITS-2 showed two possible routes, the Hwaak-san and Myeongji-san route and the Seorak-san and Gyebang-san route, for migration of ancestral C. kyebangensis into South Korea. The MSNs (MSN-A and -B) elucidate migration routes well within South Korea, especially the route of Group I and Group II.
