This study was conducted to explore the change in the market issues on HMR (Home Meal Replacements) using local foods after the COVID-19 outbreak. Online text data were collected from internet news, social media posts, and web documents before (from January 2016 to December 2019) and after (from January 2020 to November 2022) the COVID- 19 outbreak. TF-IDF analysis showed that ‘Trend’, ‘Market’, ‘Consumption’, and ‘Food service industry’ were the major keywords before the COVID-19 outbreak, whereas ‘Wanju-gun’, ‘Distribution’, ‘Development’, and ‘Meal-kit’ were main keywords after the COVID-19 outbreak. The results of topic modeling analysis and categorization showed that after the COVID-19 outbreak, the ‘Market’ category included ‘Non-face-to-face market’ instead of ‘Event,’ and ‘Delivery’ instead of ‘Distribution’. In the ‘Product’ category, ‘Marketing’ was included instead of ‘Trend’. Additionally, in the ‘Support’ category, ‘Start-up’ and ‘School food service’ appeared as new topics after the COVID-19 outbreak. In conclusion, this study showed that meaningful change had occurred in market issues on HMR using local foods after the COVID-19 outbreak. Therefore, governments should take advantage of such market opportunity by implementing policy and programs to promote the development and marketing of HMR using local foods.
This study researches the restaurant industry in Seoul during the late 1940s. The research was based on the four major newspapers in Korea. The data included a total of 227 businesses with 164 non-fusion restaurants that served single-nation type food consisting of 101 Korean, 31 Western, 20 Japanese, and 12 Chinese. Some examples of South Korean dishes are Masan, Daegu, and Jeolla-do-style local foods. As for North Korean food, Pyongyang-style bulgogi, Naengmyeon, Hamheung-style janggukbap, and Gaejangguk were introduced frequently. Chinese restaurants that appeared were highend places with Beijing-style cuisine. In the case of Japanese restaurants, they mostly had Sukiyaki with Joseon food served as well. Moreover, Western restaurants were fusioned with Japanese as in pork cutlet and curry rice. Others are comprised of “French Cuisine”, “Indian curry rice”, “Steak”, and “Russian soup”. This analysis indicates that foreign cuisines had actively entered the market.
This study applied the text frequency method to analyze the crops prevalent during the Chosunwangjoshilrok dynasty, and categorized the results by each king. Contemporary perception of grains was observed by examining the staple crop types. Staple species were examined using the word cloud and semantic network analysis. Totally, 101,842 types of crop consumption were recorded during the Chosunwangjoshilrok period. Of these, 51,337 (50.4%) were grains, 50,407 (49.5%) were beans, and 98 (0.1%) were seeds. Rice was the most frequently consumed grain (37.1%), followed by pii (11.9%), millet (11.3%), barley (4.5%), proso (0.8%), wheat (0.6%), buckwheat (0.1%), and adlay (0.05%). Grain chronological frequency in the Choseon dynasty was determined to be 15,520 cases in the 15th century (30.2%), 11,201 cases in the 18th century (21.8%), 9,421 cases in the 17th century (18.4%), 9,113 cases in the 16th century (17.8%), and 6,082 cases in the 19th century (11.8%). Interest in grain amongst the 27 kings of Choseon was evaluated based on the frequency of records. The 15th century King Sejong recorded the maximum interest with 13,363 cases (13.1%), followed by King Jungjo (8,501 cases in the 18th century; 8.4%), King Sungjong (7,776 cases in the 15th century; 7.6%).
In this study, we aimed to explore whether eating alone is associated with mental health conditions in Korean adolescents. The data of 2,012 Korean adolescents aged 12-18 years were obtained from the Korea National Health and Nutrition Examination Survey 2015–2019. Participants were classified into three groups based on the frequency of eating alone: none (all meals with others); 1 meal/day alone; and 2 meals/day alone. Mental health conditions were assessed based on stress recognition, depressive symptoms, and suicidal ideation. Multivariable logistic regressions were employed to calculate the adjusted odds ratios (AORs) and 95% confidence intervals (CIs) of poor mental health conditions according to the frequency of eating alone. Adolescents who ate 2 meals/day alone had higher odds of stress recognition (AOR: 2.65, 95% CI: 1.94- 3.63), depressive symptoms (AOR: 2.55, 95% CI: 1.47-4.42), and suicidal ideation (AOR: 2.53, 95% CI: 1.05-6.08) than those who ate all their meals with others. In addition, having breakfast or dinner alone increased the odds of stress recognition. Considering the continuous increase in the social phenomenon of eating alone, nutritional educations are needed to develop adolescents' ability to choose more nutritionally balanced and healthy meals when eating alone.
The image and emotions associated with Korean food were investigated in 24 food workers (12 Koreans and 12 foreigners) living in Korea. There are a total of 22 terms for the image of Korean food of Koreans and foreigners, including 7 common words, and a total of 33 terms for emotion, including 10 common words. Differences in the images and emotions associated with the perception of Korean food according to the characteristics of the country and region and Korean food experience were established in foreign food workers. In the images of Korean food, Koreans mentioned ‘jeong, sharing, balanced, Korean table setting, seasonal (seasonality), yearning, trust’, whereas foreigners mentioned ‘red, spicy, distinctive flavor, repulsion, sweet, non-salty, tradition and history, and unfamiliarity’. In Korean food emotions, Koreans were “relaxing, friendly, maternal, hospitable, nostalgic, exotic, clean, trust, delicious, touching, and free”, whereas foreigners were “happy, appealing, enthusiastic, excited, uncomfortable, worried, adventurous, nervous, joyful, fusion, food-cultural, and amazing”.
In this study, we identified the differences in food content watching habits and nutrition quotient in adolescent (NQ-A). A total number of 811 subjects were surveyed to establish their general characteristics, food content watching habits, and NQ-A using a self-administered questionnaire. In addition, the mediating effect of watching motivation between the type of food content watched and the NQ-A score was determined. The classification by the type of the food content mainly watched showed that 405 participants (49.9%) watched the Mukbang content, 244 (30.1%) the Cookbang content, and 162 (20.0%) another contents. Among the content watching motives in the Cookbang content group, information acquisition and enjoyment were predominant, whereas emotional satisfaction had the lowest frequency. Compared to the Mukbang content group, when the Cookbang content group mediated information acquisition motivation, the scores of the total, diversity, balance, and practice of NQ-A score areas increased. Compared to the Mukbang content group, the score in the moderation area decreased when the Cookbang content group mediated enjoyment motivation. If food content with accurate information and interesting content are produced and used for adolescent nutrition education, the education will be highly effective.
