Purpose: This study was performed to investigate the dietary behaviors and stress-related factors among male and female college students. Methods: A total of 405 college students (male-195, female-210) were recruited, of whom a questionnaire-based survey was conducted. The study investigated the general characteristics, health-related factors, dietary behaviors, and stress-related factors of the respondents. Results: The body mass index was significantly higher in males. The rates of underweight and overweight were significantly different between male and female respondents. The scores for workout frequency, health concerns and health condition were significantly higher in males, while the score for watching TV & playing computer games was significantly higher in females. The scores for meal regularity, frequency of breakfast consumption, and smoking were significantly higher in males. Eating problems showed a significant difference between males and females. The biggest source of stress was social factors, followed by college study and individual factors and the most experienced stress-induced symptom was anxiety, followed by headache and stomachache. The most popular way to overcome stress was taking a rest, followed by drinking & smoking and outdoor activity. The most preferred food under stressful conditions were alcohol or beverages, followed by hot & spicy food and sweet food, which showed a significant difference between males and females. Conclusion: These results indicate that stress affects dietary behaviors, drinking, smoking, and health status. Stress not only changes dietary behaviors, but is also related to health status. Therefore, it is necessary to develop appropriate programs for emotional stability and stress relief targeting college students which provide continuous nutrition education focused on desirable dietary behaviors and nutritional aspects.

Purpose: This study analyzed the dietary patterns of Central Asian immigrant workers (Mongolia, Kazakhstan, Uzbekistan, and Kyrgyzstan) living in South Korea to determine the food acculturation and how their dietary practices have changed after immigration. Methods: Self-administered questionnaires were completed by 186 Central Asian immigrant workers living in South Korea. A food frequency questionnaire (FFQ) was used to obtain information on the consumption frequency of 22 food items before and after their immigration to Korea. Results: Central Asians switched to Korean meat consumption patterns, which consume mainly pork, chicken, and beef, showing a decrease in the intake of beef and lamb and an increase in that of pork. Their consumption of Namul (cooked vegetable), Kimchi, rice, and marine products increased while that of potatoes decreased during acculturation to Korean food culture. Positive changes were observed in Mongolians' eating habits. Their meat-based diet turned into a healthy one in which nutritional balance was achieved by consuming the various food groups. Negative dietary changes were also observed; intake of instant foods and coffee increased while black and green tea consumption decreased. Intake of Namul (p < 0.01), Kimchi (p < 0.01), rice (p < 0.001), ramen (p < 0.001), pork, chicken (p < 0.01), fish (p < 0.01), seafood (p < 0.001), and coffee (p < 0.001) increased significantly in the group that responded and their health improved after moving to Korea. This result suggests that health improved among those who were well settled in Korea and ate the various food groups. Conclusion: These findings can help understand the acculturation process to Korean food culture and provide a basis for developing policies to help them adjust to Korean food culture.

This study was conducted to identify the major dietary patterns of Korean adult men and to examine the relationship between subjective stress perception and these dietary patterns using data from the 2014~2016 Korean National Health and Nutrition Examination Survey (KNHANES). Of the 23,080 total subjects, adult men between the ages of 19 and 64 who did not take the questionnaire or answer the questions relating to depression, and cases where the daily energy intake was less than 500 kcal or more than 5,000 kcal in the Food Frequency Questionnaire were excluded. This left a total of 3,464 subjects who were included in the final analysis. We performed a factor analysis based on the yearly mean intake frequency of 41 food groups to identify the major dietary patterns. Three major dietary patterns were identified (factor loading >0.3), including the 'Healthy pattern', 'Processed meat pattern', and the 'Alcohol pattern'. The 'Healthy pattern' was characterized by higher intake of beans, tofu, vegetable, fish, and fruits. The 'Processed meat pattern' was characterized by high consumption of processed meats and instant foods. The 'Alcohol pattern' was characterized by a higher intake of alcohol. As a response to the subject's subjective perception of stress, the most answered 'a little' according to age, marital status, occupation, income, residential area, smoking status, drinking status, and exercise status. People whose diets followed the 'Processed meat' and 'Alcohol' patterns had significantly higher scores on subjective stress perception compared to people following the 'Healthy pattern'. To manage subjective stress, it is more effective to maintain health by relieving stress through a healthy method that combines healthy eating and exercise rather than following an unhealthy diet as characterized by the 'processed meat' and 'alcohol' dietary patterns.

Objective: The aim was to compare the behavioral response to full separation of cows and calves maintained together for 100 days or 24 h. Methods: Twelve Holstein-Friesian cow-calf pairs were enrolled into either treatment or industry groups (n = 6 cow-calf pairs/group). The treatment cows and calves were maintained on pasture together for 106±8.6 d and temporarily separated twice a day for milking. The Industry cows and their calves, were separated within 24 h postpartum. Triaxial accelerometer neck-mounted sensors were fitted to cows 3 weeks before separation to measure hourly rumination and activity. Before separation, cow and calf behavior was observed by scan sampling for 15 min. During the separation process, frequency of vocalizations and turn arounds were recorded. At separation, cows were moved to an observation pen where behavior was recorded for 3 d. A CCTV camera was used to record video footage of cows within the observation pens and behavior was documented from the videos in 15 min intervals across the 3 d. Results: Before separation, industry calves were more likely to be near their mother than Treatment calves. During the separation process, vocalization and turn around behavior was similar between groups. After full separation, treatment cows vocalized three times more than industry cows. However, the frequency of time spent close to barrier, standing, lying, walking, and eating were similar between industry and treatment cows. Treatment cows had greater rumination duration, and were more active, than industry cows. Conclusion: These findings suggest a similar behavioral response to full calf separation and greater occurrence of vocalizations, from cows maintained in a long-term, pasture-based, cow-calf rearing system when ompared to cows separated within 24 h. However, further work is required to assess the impact of full separation on calf behavior.

This study was conducted to examine the effect of globalization of Korean food according to well-being value perception and the foreign visitor Korean food experience. An analysis of variance and a linear regression analysis were conducted to analyze the hypotheses. The findings are summarized as follows: (1) The most important quality when eating Korean food was "taste" (37.3%). (2) The most important well-being value recognition items for Korean food were "kimchi" and "bulgogi". "Bibimbap is well-being food" (3.82 points) and "Korean food is healthy because it consists mainly of cereals and vegetables" (3.56 points). (3) The subjects highly recognized the "improvement in service quality of Korean restaurants" (3.59 points) with regard to the importance of a globalization strategy for Korean food. (4) High-intake Korean foods were "bibimbap", "baechookimchi", "galbigui", "pajeon", and "bulgogi", in that order. In contrast, the intake frequency for "songpeon", "sikhei", and "guksu" was very low. (5) The subjects thought that the globalization possibility for Korean food was high, as foreigners ingested a lot of baechookimchi. (6) The most effective well-being value recognition item for globalizing Korean food was "Korean food is nutritious and good for the health" followed by "I have much interest in Korean well-being food". and "Korean food is a well-being food because it contains many fermented and seasonal items", in that order. (7) The most effective food for globalizing Korean food with a high-intake frequency was "baechookimchi", followed by "galbigui", "guksu", and "bibimbap".

Mercury is a chemical pollutant widely present in the environment. Humans are generally exposed to mercury in the form of organic Hg (methylmercury) through the consumption of seafood. Koreans enjoy eating fish therefore blood mercury concentration is usually higher than in developed countries. By investigating blood mercury concentration according to the frequency of seafood consumption and sociodemographic factors, we aimed to identify recent trends in blood mercury concentration in Korean adults. This study was conducted using KoNEHS cycle 4 (2018~2020) from the National Institute Environmental Research Survey. The geometric mean concentration of blood mercury of the subjects was 2.959 (±1.018) ㎍/L, which was significantly higher in men than in women. It was observed that as the frequency of fish and shellfish consumption increased, the blood mercury concentration increased. In adjusted logistic regression, fish consumption was associated with 36.7% increased risk of blood mercury levels [Odds ratio, 1.367; 95% confidence interval (CI), 1.246~1.500], and shellfish consumption was associated with 26.5% increased risk of blood mercury levels [Odds ratio, 1.265; 95% confidence interval (CI), 1.134~1.410]. Blood mercury concentration was also found to increase as the socioeconomic level increased. In conclusion, the geometric mean concentration of blood mercury was increased compared to the one in the 3rd KoNEHS (2015~2017) and seafood consumption and socioeconomic level were still significantly associated with increasing blood mercury concentration in Korea. Therefore, it is necessary to encourage healthy seafood consumption habits and conduct continuous monitoring considering various factors to reduce blood mercury levels.

The purpose of this study was to evaluate vegetable intakes according to body mass index (BMI) of adolescents. For this, 400 middle and high school adolescents living in Buyeogun, Chungnam were classified into underweight group, healthy weight group, and overweight group according to BMI, after which eating habits, daily intake levels of vegetables, perception of vegetables, and vegetable-related eating habits were compared and analyzed. As the reason for skipping breakfast, 'Lack of time (44.3%)' was the most frequently cited. In the case of unbalanced food intakes, the underweight group and overweight group showed the highest response for 'grain' while the healthy weight group showed the highest response for 'vegetables' with significant differences (P<0.001). Daily intakes of one serving size of vegetables was 3.3 in the underweight group, 3.8 servings in the healthy weight group, and 3.8 servings in the overweight group, but there was no significant difference. However, frequency of vegetable intake at lunch was once in the underweight group, which was significantly lower than 1.3 servings in the healthy weight group and 1.4 servings in the overweight group (P<0.05). Regarding perception of vegetables, perception of 'Vegetable consumption helps to get beautiful skin' (P<0.01) and 'I eat vegetables or don't eat depending on a cooking method' (P<0.05) were significantly higher in the underweight group. In the evaluation of vegetables-related eating habits, preference for vegetables in the underweight group was lower than that in the healthy weight and overweight groups (P<0.05). Summarizing the above results, vegetable intake by adolescents was generally low, and the frequency of vegetable intake at lunch as well as preference for vegetables were significantly lower in the underweight group. Studies to identify the relationships between adolescent body types and vegetable intakes are required.

The purpose of this study was to investigate the perceptions and preferences held by the general public concerning jeungpyun. Self-administered questionnaires were collected from 484 residents in Daegu and Gyeongbuk. The questionnaires contained questions on the recognition of jeungpyun, purchasing, frequency, purchasing factor, and preferences for and purchasing of jeungpyun containing different kinds of makgeoilli. According to the survey, females were higher than males (31.4%) by 69.7%, and that for ages 20~30' was the highest. Most of them were students (39.7%), and 81.7% of them had an income of under 4,000,000 won per month. The results of the eating frequency rate showed that over half of the people had jeungpyun once a month, and the recognition of jeungpyun for females (3.63) was higher than that for males (3.09). The respondents who joyed eating jeungpyun mentioned 'good taste and texture' as the top reason for eating jeungpyun, and 'different food and bad flavor' was mentioned as the reason for disliking it. As a result, popularization of jeungpyun was based on two factors: 1) fundamental factor and 2) external factor, and both significantly influence the preference for and purchasing of jeungpyun,-. Therefore, future studies should be conducted to improve preference for jeungpyun as a functional food. The results of preference and purchasing show that jeungpyun prepared with rice, rubus coreanum miquel, black bean, grape and green mume makgeoilli.
