BACKGROUND/OBJECTIVES: This study aimed to assess the dietary behaviors of preschool children using the nutrition quotient for preschoolers (NQ-P) and analyzed the difference in the scores of the children's dietary behaviors in regards to the parents' health consciousness. SUBJECTS/METHODS: The subjects were 257 children aged 3-5 years and their parents residing in Seoul and Gyeonggi-do, South Korea. The questionnaire is composed of demographic characteristics, the NQ-P questions, and health consciousness. All data were statistically analyzed by SPSS program (ver. 25.0) and the statistical differences in variables were evaluated by χ2 test, Fisher's exact test, t-test, 1-way analysis of variance and Tukey's multiple comparison test. RESULTS: There was a significant difference on the intake frequency of processed meat by region and fast foods by age, region, and weight status (P < 0.05). There was also a significant difference in not moving around while eating by weight status and parents' effort to have healthy eating habits by sex (P < 0.05). The mean score of NQ-P of the total subjects was 59.47, which was within the medium-low grade. The mean score of balance was 61.62, and the boys were significantly higher than girls (P < 0.05). As the age of children increased, the mean score of the moderation was significantly decreased (P < 0.05). The scores of NQ-P (P < 0.05), balance (P < 0.01), and environment (P < 0.05) were significantly higher in the high group of parents' health consciousness than the low group. CONCLUSIONS: According to the results of the evaluation by NQ-P, the dietary behaviors of preschoolers residing in Seoul and Gyeonggi-do need to be improved. For improving their eating behavior and nutritional health status, parents and children need customized nutrition education programs based on sex, age, region and weight status of preschool children as well as the degree of parents' health consciousness.

The digital environment has become an integral part of human lives today. This study aimed to investigate Mukbang watching status and its association with eating behaviors, eating habits, and the nutritional status of children. We conducted a survey of the actual status of Mukbang watching, and nutrition quotient of children (NQ-C) among 222 students in elementary schools in Daejeon. The prevalence of viewing Mukbang content was 68.9%, the most common frequency of viewing was 1~2 times per month (36.5%), and the duration of watching a single episode was less than 10 minutes (54.9%). Overall, 31.4% of students responded that they ate while watching a Mukbang and, 66.0% said they felt hungry after watching a Mukbang. YouTube (82.4%) was the most common source of viewing Mukbang. The most common reason for watching Mukbang was because all the students found the content entertaining. The NQ-C score of all the subjects surveyed was 58.95, which is a moderate grade. The scores of NQ-C, balance, and practice factors were significantly higher in boys than in girls. In addition, the scores of NQ-C, and balance and moderation were significantly higher in Mukbang non-viewers than viewers for all subjects and more specifically boys. These results suggest that watching Mukbang is associated with poor nutritional status in elementary school children. Therefore, it is necessary to consider the Mukbang watching status when providing nutrition guidance to instill healthy eating habits in children.

Subsocial behavior of the genus Cryptocercus cockroaches has been believed as primitive traits of termite eusociality. Thus, it has been believed that understanding Cryptocercus subsociality is a pre-requisite stage to infer evolutionary route of the eusociality in termites. Woodroaches of Cryptocercus are also well known because of its peculiar characteristics including adults living monogamously in pairs, semelparous reproduction, xylophagy, obligatory association between adults and their offspring, slow development, and anal trophallaxis by adults. Based on the previously accumulated data, we try to understand two major components of Cryptocercus life history, development and reproduction. We hypothesize that harsh winter and length of winter might be one of the main causes driving the appearance of the delayed development and semelparous reproduction in Cryptocercus life history.

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.

The purpose of this study is to investigate snacking behavior of high school students. The subjects were 1,587 students (684 male, 903 female) in Seoul and Paju. The highest number of eating snacks was 'once(39.9%)' per day, and they preferred 'milk and cookies' and 'fruit.' For the result of reasons for choosing a snack, they chose 'what I want to have (59.6%)' most and 'snacks don't affect eating meals (48.0%).' Also, compared with the ones with 'an elementary school diploma,' the percentage of those with 'a middle school diploma' was higher in 'having snacks once or three times' according to father's education level(p<0.05). In snack types and general characteristics, they chose 'milk and cookies' when their expenses range 'under 50000 won' and '100,000 won' and 'fruit' when '70,000won' and 'over 100,000 won (p<0.05).' In the reasons for choosing a snack, younger mothers(30-50ages) said 'what I want to have' while elder mothers($$\geq_-51ages$$) 'depending on my mood.' Also, the respondents whose mothers had 'a high school diploma' answered 'what I want to have' the most (p<0.05). Especially, in case of effects after eating snack, they answered 'poor meals (35.5%)' whose mother's job was professional. These results suggest that the general characteristics of family environment may affect snacking behavior among high school students. They need a guideline to help select healthy snacks for desirable eating behavior.

This study investigated eating behaviors (life-style, breakfast pattern, eating environment, snack pattern, and awareness of breakfast) by breakfast frequency (0~2 times, 3~6 times, and 7 times per week) of high school students (146 males and 165 females) in the Yongin region. The percentage of 'mother' as breakfast preparer increased with elevated breakfast frequency, whereas 'myself' was lower for females (P<0.001). Regarding reasons for skipping breakfast, 'getting more sleep' increased with elevated breakfast frequency, whereas 'loosing appetite' decreased in males (P<0.001). Regarding family reaction to skipping breakfast, 'advising' increased with elevated breakfast frequency in females (P<0.001). Skipping breakfast by eating snacks was higher in females (51.6%) than in males (35.6%), and skipping dinner was higher (53.4%) in females. Awareness of breakfast importance increased with elevated breakfast frequency in males (P<0.05) and females (P<0.001). Perception of correlation between health and breakfast was higher in females (54.8%) compared to males (43.9%), and the most important reason was 'energy supplement'. 'Eating now and will eat' increased with elevated breakfast frequency in males (P<0.001) and females (P<0.001), whereas sum of 'not eating now and will not eat' and 'eating now but will not eat' were 19.2% and 14.2% in males and females, respectively. Therefore, appropriate education programs emphasizing importance of eating breakfast and environmental improvement for regularly eating breakfast for high school students are highly required.
