Generation Z(Gen Z), which is referred to people in their late teens to early 20s, becomes one of new major consumer groups in the society. More than 80 percent Gen Z use YouTube content as a main information channel. In this study, we investigate what kind of factors make Gen Z immersed when watching YouTube content. In the background study, we examined immersion and set the cognitive conditions of immersion as reality, fascination, control, and driving as a framework for analysis of case study. In the case study, we analyzed the most popular YouTube channels of each category among the Gen Z with the established framework and then identified 3 main factors: reality, 5 senses, and unpretentiousness and 8 characteristics of them. By conducting survey with Gen Z, we wanted to verify the validity of the characteristics and find out the difference among categories. Subjects answered on a five-point scale how the characteristics of each immersion factor corresponded to their favorite channels. As a result, seven characteristics: 1) familiarity of background, 2) reality of acting, 3)familiarity of material, 4)YouTubers' appearance and 5) voice, 6)multi-sensory, and 7)YouTuber's ability to resemble viewers influenced more than 50% of users' immersion. Although there was no significant difference among categories, the familiarity of the material and the five senses stimulus (YouTube's appearance, voice, audiovisual and surrogate taste) were the most important factors in the entertainment category.

Recently the Ministry of Health and Welfare, Republic of Korea, announced the “Dietary Guidelines for Korean Adults (DGKA)”, which includes ten Dietary Goals, six Dietary Guidelines, and twenty-three Action Guidelines. DGKA are developed as the revision of the 2003 Dietary Guidelines for Koreans, targeting adult population. Dietary Guidelines are developed for general purpose as well as for different age groups. They are revised periodically to accommodate changes in diet and health problems of the population. The process of developing new DGKA can be summarized as 1) selection of focus areas, 2) analysis and review of available data for each area selected, and 3) derivation of guidelines based on the analyzed data, and 4) finalizing the guidelines after open discussions among the experts and general public. Five focus areas were selected by examining the Nutrition Goals of the Health Plan 2010 of Korea, soliciting proposals from the experts in the related fields, and reviewing existing and international guidelines. Five areas selected were 1) adequate intake of nutrients and foods, 2) balance of energy intake and physical activities, 3) alcohol intake, 4) food security and nutrition service, and 5) food safety. Adequacy of nutrient and food intakes of the Korean adult population was assessed using 2005 Korea National Health and Nutrition Examination Survey (KNHANES) data. Newly developed Dietary Reference Intakes for Koreans were used as reference values to assess the prevalence of inadequacies and excesses in nutrient intakes. Energy balance was examined with energy intake of 2005 KNHANES survey and results of physical activity questionnaire in the survey. Alcohol intake was also examined using 2005 KNHANES results of dietary intakes as well as the results of questionnaire survey on alcohol intakes. Food security, nutrition services, and food safety were analyzed using various government data and published results on the issues. Ten Dietary Goals and six Dietary Guidelines were developed after data analysis and were subjected to reviews of experts and general public. The final DGKA are: 1) Eat a variety of foods from each food group, 2) Increase physical activity and maintain healthy weight, 3) Eat proper amount of clean foods, 4) Avoid salty foods and try to eat foods with bland taste, 5) Avoid foods with high fat contents and deep-fried foods, and 6) When you drink alcohol, limit the amount. Twenty-three action guidelines are developed in order to achieve these guidelines in actual diet and life among the population. The government is disseminating the guidelines with “337” slogan and emblem. “337” indicates everyone should practice “3” guidelines of promoting good eating practice, “3” guidelines to limit or decrease in your diet, and you should practice them for “7” days a week. The guidelines will be useful in promoting healthy food habits and good nutritional status which will result in decrease nutrition related health problems in Korea.

The taste and quality of soy sauce, a fermented liquid condiment, is greatly influenced by microbial metabolism during fermentation. To investigate the microbiological characteristics of ganjang during the initial fermentation process, we prepared meju (fermented soybean) blocks fermented with starter cultures and solar salts and analyzed the microbial community quantitively using 16S rRNA gene profiling from ganjang that had been fermented over a five-week period. The ganjang samples were collected and analyzed after soaking for week one (1W), three (3W), and five (5W) weeks. We found that Halomonadaceae was significantly higher in the 1W group (89.83%) than the 3W and 5W groups (14.46%, and 13.78%, respectively). At a species level, Chromohalobacter beijerinckii and Chromohalobacter canadensis were the dominant species in the 1W group but several taxa such as Bacillus subtilis, Pediococcus acidilactici, and Enterococcus faecalis were more abundant in the 3W and 5W groups. Pearson correlation analysis of the relative abundance of the bacteria showed a negative correlation between Chromohalobacter and two bacterial genera Bacillus and Enterococcus. Beta-diversity showed a statistical distinction between the 1W and the 3W and 5W groups, while no significance was evident between the 3W and 5W groups. Linear discriminant effect size analysis was used to identify biomarkers and significant differences in the relative abundance of several halophilic bacteria, Bacillus sp. and lactic acid bacteria at 1W, 3W, and 5W, recpectively, which indicates the important role of the bacterial community at these time points.

Improving the taste of rice in the breeding process is one of the important goals. However, it takes a lot of time and effort to select lines with good grain quality. MAS related to rice quality can help quickly and accurately select the elite lines in breeding programs. QTL qTV9, derived from Wandoaengmi 6, has been reported as a marker associated with improved glossiness of rice (Park et al., 2019). To confirm the function of QTL qTV9, 186 RILs derived from Hwayeong/Wandoaengmi6 were cultivated on ordinary planting cultivation for five years. The average DTH of Hwayeong and Wandoaengmi 6 was not significant at 99 and 97 days, respectively, but the averages of TV (toyo value) were 72.6 and 86.0, respectively. The DTH and TV of RIL vary from year to year. In 2017-2018, the average DTH was 98 days, which was significantly higher than the other three years. In 2018 and 2021, the average TV was 79.5 and 86.5, respectively, which were significantly higher than in other years. As a result of correlation analysis, DTH in the different years showed highly significant positive correlations (r = 0.71-0.92) from 0.71 to 0.92, whereas TV showed positive but weaker correlations (r = 0.42-0.71). The correlation between DTH and TV in each year was significant but weak (r = 0.25-0.64) and there was no correlation in 2017. The TV (77.6-88.7) of RILs with QTL qTV9 was significantly higher than that of RILs without qTV9 (72.6-84.9) for all five years. As a result of analyzing TV by DTH group, the TV of the lines with qTV9 in DTH groups (93-97) and (98-103) showed a significantly higher trend for all 5 years. And TV was not significant in DTH groups A, B, E, and F. This may have been influenced by factors such as insufficient populations between groups or differences in harvest timing. This study is expected to be used as data for improving the glossiness of cooked rice in breeding programs, and further study of the QTL qTV9 marker is required.

Varietal difference of eating quality by milling degree was investigated for total nine rice varieties comprised of three varieties each as excellent, good, and normal according to sensory evaluation results of cooked rice. Nine varieties were analyzed for their physicochemical properties and for the sensory evaluation according to five different degree of milling(5.5~13.5% based on brown rice). Overall score obtained through sensory evaluation was found the best in the milling degree at 9.5% and 11.5%. The overall score by rice variety was categorized into type A that showed high score at milling degree 9.5%, type B at milling degree 11.5%, and similar type C at both milling degrees 9.5% and 11.5%. The best eating quality was observed in Ilmibyeo and Koshihikari having overall eating quality excellent at milling degree 9.5% and in Chucheongbyeo and Dongjinbyeo having overall eating quality good at milling degree 11.5%. While, Palgongbyeo and Nonghobyeo having eating quality normal showed the best eating quality at milling degree 9.5% and 11.5%. Correlation analysis between overall score and physicochemical properties and five sensory evaluation items by three types of rice showed that Mg content and stickiness of type A, protein content and taste of type B, and K content and appearance of type C were highly significant correlation on overall score by panel test. Therefore, Mg contents might have affected on the stickiness of cooked rice in type A, protein contents on the taste in type B, and K contents on the appearance in type C, respectively.

The objectives of this study were to explore food-related lifestyle segments of the older consumers, to identify its socio-demographic characteristics, and to investigate the differences in variables regarding health beliefs. A survey was conducted of adults 55 years of age and older living in Seoul, South Korea from March 28 to April 10, 2007. Out of the 500 distributed questionnaires, 361 were retained for final analysis: a response rate of 72.2%. As a result of cluster analysis, five consumer segments were identified; health-managing group, diet-unconcerned group, convenience-oriented group, taste-oriented group, unpracticed group. Significant differences were found among the five segments in terms of socio-demographic characteristics and variables regarding health beliefs (i.e., perceived self-efficacy, perceived barriers, perceived benefits). In the health-managing group and taste-oriented group, mean scores of perceived self-efficacy (p<0.001) and perceived benefits (p<0.001) were significantly higher than other groups. However, in the diet-unconcerned group and convenience-oriented group, the mean scores of perceived barriers (p<0.01) were significantly high. This study shows that foodservice operators targeting the older consumers should consider characteristics of each segment to develop a customized program.

This research investigated the eating out and snack intakes situation of five hundred eighty five $5^{th}\;and\;6^{th}$ graders living in the city and rural parts of Jeonbuk province. The results of this study are as followed: Nuclear families in urban area and rural community are 84.5% and 64.7% respectively. On the other hand, extended families are 7.9% in urban area and 18% in rural communities. Out of all the households, 34.3% (urban: 37.2%, rural community: 31.5%) answered they like to eat out. Over 50.3% preferred eating Korean style food and the reason was 'the taste': urban (71.4%) and rural community (67.8%). People living in urban communities seemed to eat out more frequently than rural places and $3{\sim}4$ times a month was the average. Usually people seemed to eat out during the weekends and in the evening time 84.3% (after 7:00 p.m.). Based on each family's living standard, people answered 'we hardly ever eat out' for those in the lower class (59.1%), the middle class said once or twice a week (47.1%), and the upper class (35.7%). It was obvious that people in the middle and upper class tend to eat out more frequently than those in the lower class. The most common period of time which snacks were taken was after school (38.5%), on the way back from educational institute (35.0%) and the choices of snacks which they purchased were frozen sweets (56.4%)chips & cookies (25.2%) beverages (9.9%) Fast foods (4.6%) and fried foods (3.9%) in order. Urban children seem to eat more frozen sweets and rural children ate more chips & cookies. Also, amount of snacks between meals showed a higher percentage to those who had more pocket money, The type of snacks were fruits (37.1%) chips and cookies et cetera (19.2%) instant foods (12.8%) dairy products (11.1%) confectionary (10.3%) fried foods (5.1%) in order. The result shows that urban children eat out more frequently than those in rural areas, Eating around 7:00 p.m. was most common and the middle and upper class tend to eat out more frequently than those in the lower class, Also, snacks were most often bought before and after school. After 10:00 p.m frozen goods and chips were the most preferred choice. Specially, the reason for eating fast foods was because of the pleasing taste. From this study, it is clear that eating out and having snacks became pervasive into our lives in both urban and rural areas. Hereafter, an appropriate eating habit should be correctly educated to elementary students by spoken words and textbooks in a curriculum. In reality, snacks are classified as being the leading factor of obesity. Therefore more products containing balanced nutrition should newly develop rather than snacks with high fat content.
