The purpose of this study was to compare and analyze dietary self-efficacy and Nutrition Quotient (NQ) according to the degree of food-related content use in university students. From October to November 2022, a total of 332 college students (140 males and 192 females) attending universities in Chungcheongbuk-do were surveyed to collect data on general information, food-related content use level, dietary self-efficacy, and NQ for adults. The average dietary self-efficacy score of the group that did not use food content was 3.08 points, which was significantly higher than the group that watched it sometimes (2.89 points) and the group that watched it often (2.83 points) (p=0.0191). The total NQ score of 48.85 points was the highest among the three groups (p=0.0270). For subjects who responded that they had no experience of eating food at all after using food content, their dietary self-efficacy was 3.03, which was significantly higher than the group with occasional or frequent food consumption experience (p=0.0194). Results of this study can be used as basic data for clarifying the relationship between the use of food-related content and eating habits in university students and for proper eating habits education for university students.

The main objective of this research was to investigate the Korean food (Hansik) Curriculum of Culinary Art & Science related department of mainly four-year universities in Korea. To accomplish this study, we performed an analysis regarding curriculum data from the homepage of nine universities. The method of this research was conducted by content analysis. The classification according to content analysis was conducted to 1) current status regarding Korean Food related curriculum, 2) a study on the Korean food related theoretical curriculum, and 3) a study on the Korean food related practical curriculum. As a result of this study, the most common opened curriculum was 'a study on the Korean food related practical curriculum'. The largest curriculum among 'a study on the Korean food related practical curriculum' was the Korean cooking skill of basic and intermediate. The following curriculum was the Korean traditional and royal cuisine related curriculum. These two curriculum were found based on data of Culinary related departments of mainly four-year universities in Korea. To summarize these results, in the cases of the general culinary-related departments, Korean food-related classes will need expansion. In addition to Korean food-related departments, increasing the opening of classes to learn regarding Korean foods will be needed.

It has emerged Food-content among various forms of 1-person media through social media. Food-content influencer also market products through 1-person media, generating revenue through increased views and subscribers of 1-person media. It also sells products through sponsorship. In general, there is a profit structure through 1-person media viewing, but research on how restaurant companies generate profits directly through food-content is insufficient. In addition, research on converting subscribers to consumers through food-contents is minimal. In this paper, we propose an experiential application system based on the behavior of food-content creators. The proposed system collects and categorizes food-content information, and maps between highly related words to organize into keyword categories. The ontology tag-based concept network applied to the proposed system connects representative information by pre-extracting/mapping information related to information requests among a wide range of data. This method maps relevant food-content information to provide the user with data collected/storage in the form of an application. The user uses the application while watching the food eaten by the influencer and creator. And, it is meaningful that the user could be provided is provided with information about the food they want to eat.

BACKGROUND/OBJECTIVES: This study investigated the relationship between adolescent food-related lifestyles and food-related media use and eating behavior in Korea. SUBJECTS/METHODS: Participants were 392 Korean adolescents, ranging in age from 12 to 18, recruited via convenience sampling. They completed a self-report questionnaire survey consisting of questions about food-related lifestyle, food-related media use, food consumption behavior, food literacy, and nutrition quotient. Data analysis was conducted using SPSS 29.0. (IBM Co., Armonk, NY, USA). RESULTS: The factor analysis of food-related lifestyles identified four factors. Based on the cluster analysis results, participants were classified into three clusters reflecting different levels of interest: high interest in food, moderate interest in food, and low interest in food. The analysis revealed significant differences between groups in food-related liestyle factors (P < 0.05). Notably, the high-interest group demonstrated proactive engagement with food-related content, a willingness to explore diverse culinary experiences, and a conscientious consideration of nutritional labeling during food purchases. In contrast, the low-interest group reported tendencies toward overeating or succumbing to stimulating food consumption post-exposure to food-related content, coupled with a disregard for nutritional labeling when making food choices. A stronger inclination toward a food-related lifestyle was positively correlated with higher levels of food literacy and nutrition quotient. CONCLUSION: This study proposes that the implementation of a nutrition education program using media could effectively promote a healthy diet among adolescents with a high level of interest in their dietary habits. For adolescents with low interest in their dietary habits, it suggests that introducing an education program with a primary focus on enhancing food literacy could be beneficial in fostering a healthy diet. Our research findings provide insight for the development of tailored nutritional education programs and establishment of effective nutrition policies.

The purpose of this study was to evaluate the important changes and the trends in Korean newspaper articles related to 1) food habits and food consumption patterns 2) nutrition, health and diseases 3) food safety and policy. The method used in this study was content analysis of the articles pressed in Donga ilbo and Choseun ilbo from January 1960 to June 1996. Among the total 1814 articles, those on nutrition, health and disease were 922 (50.8%), food safety and policy were 490 (27%) and food habits and consumption patterns were 402 (22.2%). The articles related to food habits and consumption patterns dealt with four contents, food habits reformation, changes in food consumption patterns, nutritional status and food habits. The frequencies of food habits content were highest (51.1%) and especially increased in 1980's and 1990's as the concerns on health and pursuit of convenience were increased. Most of contents related to food habits were health and longevity diet (44%) and eating out (27.5%). The percentile of food habits reformation, the changes in food consumption patterns and nutritional status were 20.1%, 18.4% and 10.0%, respectively. The contents of food habits reformation were most interested in 1960's when food shortage and poverty prevailed. Nowadays, the major subjects of food habits reformation were changed to the problem of wastage and the use of our agricultural foods. The frequencies of change in food consumption patterns were gradually increased from 1960's (7 item) to June 1996 (34 items). And the most of contents related to nutritional status were focused on suffering from food shortage especially in 1960's.

Excessive sodium intake leading to hypertension, stroke, and stomach cancer is mainly caused by excess use of salt in cooking. This study was performed to estimate the salt content in school meals and to compare differences in perceptions related to sodium intake between students and staffs working for school meal service. We collected 382 dishes for food from 24 schools (9 elementary, 7 middle, 8 high schools) in Gyeonggi-do and salt content was calculated from salinity and weight of individual food. The average salt content from elementary, middle, and high school meals were 2.44 g, 3.96 g, and 5.87 g, respectively. The amount of salt provided from the school lunch alone was over 80% of the recommended daily salt intake by WHO. Noodles, stews, sauces, and soups were major sources of salt intake at dish group level, while the most salty dishes were sauces, kimchies, and stir-fried foods. Dietary knowledge and attitude related to sodium intake and consumption frequency of the salty dishes were surveyed with questionnaire in 798 students and 256 staffs working for school meal service. Compared with the staffs, the students perceived school meals salty and the proportions of students who thought school meals were salty increased with going up from elementary to high schools (P < 0.001). Among the students, middle and high school students showed significant propensity for the preference to one-dish meal, processed foods, eating much broth and dipping sauce or seasoning compared with the elementary students, although they had higher nutrition knowledge scores. These results proposed that monitoring salt content of school meals and consideration on the contents and education methods in school are needed to lower sodium intake.

Content analysis of food advertisements was undertaken to investigate the nature of the messages related to health, nutrition or consumer-promotion in 2001 women's magazines. Advertisements on baby foods were collected from three women's magazines and the final samples obtained were 42 different copies of advertisements. All the messages in each sample were counted and calculated for their frequency (％). Messages were categorized into four areas (health, nutrition, non-nutrition, consumer promotion), and each area was classified into more detailed categories. Results showed that all the messages in 42 samples and average messages per advertisement were 1288 and 30.7, respectively. The most common type of promotional messages was health related (e.g., appeal to enhanced immune function and disease prevention and brain development), followed by consumer related, nutrition and non-nutrition messages in order. Messages about high quality and all natural ingredients were more emphasized in the consumer related category. Messages on fats (DHA, lecithin and arachidonic acid), proteins (neucleotides, taurine) and mineral (calcium, iron) were most frequently found in nutrition category. Amongst the three kinds of baby foods, formula ads had the most numerous messages related to health and nutrition. There were more consumer related messages in the ads of weaning foods, and more promotional messages about no addition of antiseptic, artificial additives, and food colors in the ads for older infant foods. Messages violating regulation (e.g., exaggerated or inaccurate or non-scientific messages) were frequently found in the advertisements of three kinds of baby foods. In conclusion, tighter supervision of food advertisements and nutrition education is required to protect the consumers from misleading advertisements.

Various cell wall polysaccharides and related enzyme activities in hot pepper fruit were determined at different stages of maturity. The uronic acid content of cell walls decreased between immature green and turning stage fruit and then increased by red ripe stage. In contrast, cellulose content of cell walls changed only a little during ripening. Total neutal sugar content of cell wall material decreased 50% and galactose content of the walls decreased about 80% by the turning stage. Polygalacturonase and ${\beta}-galactosidase$ activities, as well as total hemicellulose from isolated cell walls of ripening hot pepper fruit were studied using gel filtration chromatography. Polygalacturonase activity was not detectable but 5 isozymes of ${\beta}-galactosidase$ were resolved. The activities of the enzymes were relatively high and gel filtration showed that they differed in molecular weight. Hemicellulose content decreased during ripening and softening. The molecular weight profiles shifted from high molecular weight to low molecular weight polymers during ripening. The changes in cell walls that may be associated with fruit softening involve the alteration of hemicellulose prior to the degradation of wall-bound uronic acid. It is suggested that the decrease in cell wall galactose involved changes in turnover of new cell wall components.

The aim of this study was to compare the American, Chinese, and Japanese consumers' usage behavior of marketing communication towards overseas Korean restaurants. The survey included both on and off-line method and self-administered questionnaires were written in three languages- English, Chinese and Japanese. The sample was collected from 5 hub cities for globalization of Korean food- LA, New York, Tokyo, Beijing, and Shanghai. The most important factor of searching for Korean restaurants-related information was 'the interaction' and the least one was 'the diversity'. The most commonly informed Korean restaurants-related content through the on and off-line media was 'the general information, such as location, telephone number, and operation hour'. Korean restaurants-related content that the respondents' most interested in was 'the information of menu and price'. Results of this study can expectedly be used from a practical point of view by providing empirical data of foreign consumers for effective marketing communication strategies of overseas Korean restaurants.
