Food webs have received global attention as next-generation biomonitoring tools; however, it remains challenging because revealing trophic links between species is costly and laborious. Although a link-extrapolation method utilizing published trophic link data can address this difficulty, it has limitations when applied to construct food webs in domestic streams due to the lack of information on endemic species in global literature. Therefore, this study aimed to develop a link extrapolation-based food web model adapted to Korean stream ecosystems. We considered taxonomic similarity of predation and dominance of generalists in aquatic ecosystems, designing taxonomically higher-level matching methods: family matching for all fish (Family), endemic fish (Family-E), endemic fish playing the role of consumers (Family-EC), and resources (Family-ER). By adding the commonly used genus matching method (Genus) to these four matching methods, a total of five matching methods were used to construct 103 domestic food webs. Predictive power of both individual links and food web indices were evaluated by comparing constructed food webs with corresponding empirical food webs. Results showed that, in both evaluations, proposed methods tended to perform better than Genus in a data-poor environment. In particular, Family-E and Family-EC were the most effective matching methods. Our model addressed domestic data scarcity problems when using a link-extrapolation method. It offers opportunities to understand stream ecosystem food webs and may provide novel insights into biomonitoring.

기존 질병비용연구(COI)에서 환자의 여가시간 손실에 따른 경제적 영향은 상대적으로 적은 관심을 받아왔다. 또 한, 기존연구들은 주로 만성질환 또는 중질환에 초점을 맞 췄으며, 이로 인해 입원환자나 외래환자가 아닌 상대적으 로 증상이 약한 자가치료환자들에 대해서는 충분히 다루 지 못했다는 한계를 가지고 있다. 이에 본 연구에서는 자 가치료 환자들을 포함하고, 더 나아가 고용 상태와 실제 여가활동 중단 기간 등을 고려하여 식중독으로 인한 여가 손실의 연간 비용을 계산하였다. 이 과정에서 건강과 노 동에 관한 통계 자료를 활용하고, 식중독으로 인한 여가 손실을 정확히 평가하는 방법을 제시하였다. 연구 결과, 국내에서 식중독으로 인한 여가 손실에 따른 연간 경제적 비용은 약 7,845억 원(7억 2,800만 USD)으로 나타났다. 본 연구에서는 자가 치료 환자들을 포함하지 않거나 치 료 시간과 고용 상태를 고려하지 않은 경우, 여가손실비 용이 낮게 추정될 가능성을 제시하고 있다. 즉, 식중독과 같은 질병의 사회적 영향을 평가할 때 자가 치료, 고용 상태, 그리고 영향받는 전체 기간을 포함한 다양한 요소 를 고려하는 것이 중요하다는 것을 의미한다. 이 연구 결 과는 정책 결정자와 의료 전문가들에게 질병의 경제적 영 향을 보다 넓은 관점에서 이해하고, 보건의료 자원을 더 효과적으로 배분하는 데 도움이 될 수 있는 중요한 통찰 을 제공한다.

본 논문에서는 1973년 프랑스 파리에 최초로 한식당을 창업하여 30여 년간 운영한 한인 이민사업가를 대상으로 유럽에서의 요식업 종사 경험 을 구술생애사적 관점에서 고찰한다. 프랑스 한인사회의 역사적 변천 과 정의 맥락에서 구술자의 한식당 창업 동기와 사업에 도움이 되었던 요 인, 한식당 경영의 의미에 대해서 조사한다. 연구 결과에 따르면 구술자 는 유럽에서의 연속적 이주 과정을 통해서 축적한 다양한 사회적 네트워 크를 주요한 민족자원의 하나로 활용하였다. 또한 창업 당시 프랑스 한 인은 200명 남짓의 소규모였고 현지인들 사이에 한국, 한국 음식에 대한 인지도가 매우 낮았기 때문에, 입지 선정에 있어서 주프랑스 한국대사관 과의 근접성이 중요하게 고려되었다. 한식당 경영을 통해서 프랑스 한인 과 한국으로부터의 방문객들이 모국의 음식을 향유하고 한국적 정서를 접할 수 있게 하였고, 또한 프랑스 현지인들에게는 한국 음식문화와 한 인 예술을 알리는데 기여하였다. 본 연구를 통해 프랑스 한인 이주사, 한 인 디아스포라의 자영업 창업, 해외 한식문화의 전파와 의의에 대한 이 해 제고에 기여할 수 있을 것이다.

A checklist of dietary behavior items for the elderly was developed based on Korean dietary guidelines. First, a literature review was conducted, and 63 preliminary items, including 30 items on food intake, 12 on eating habits, and 21 on dietary culture, were obtained to evaluate the dietary guidelines. The preliminary items were evaluated by experts using Lawshe’s method to verify the content validity. They were then revised, resulting in 52 items: 25, 11, and 16 in the food intake, eating habits, and dietary culture domains, respectively. A face-to-face survey was conducted on 331 people over 65 years of age in the metropolitan area, and their one-day food intake was surveyed using a 24-hour recall method in August 2022. The 48 items, including 24, 11, and 13 items on food intake, eating habits, and dietary culture, respectively, correlated significantly with the evaluation indicators of nutrient intake, such as mean adequacy ratio, dietary diversity score, and nutrient intake density. These items were considered suitable for evaluating the elderly's compliance with dietary guidelines.

Food is essential for sustenance and reflects a country’s identity, making it crucial to identify the cultural needs for effectively localizing Korean food. This study surveyed 825 adults from four continents (eight countries) to examine their preferences, familiarity, and attitudes toward Korean food. Significant correlations(p< .001) were found between the familiarity and preference for Korean food, with variations observed across continents. Among the representative Korean food items, the average preference score was 4.67, and the purchase/recommendation intention score was 4.88. Seven items received above-average ratings (e.g., gogi-deopbap and kimchi-bokkeumbap), while some items showed high liking but low purchase/recommendation intention (e.g. dak-jjim and galbi-jjim). In addition, items such as gimbap and tteokbokki had high purchase/recommendation intention but low liking, and kimchi and vegetable foods etc. received low liking and purchase/recommendation intentions. In terms of the preferred meat according to the cooking method and seasoning, beef respondents preferred grilled · stir-fried and soup·stew·hot pot cooking methods, while pork or chicken respondents preferred grilled · stir-fried and frying methods. Soy sauce was the most preferred seasoning for all meat responses, followed by red pepper paste. These research findings provide fundamental data for developing Korean food products, segmented by continent.

We conducted a local survey targeting 300 Filipino consumers and analyzed them through multi-regression to help with the sales strategy of Korean agricultural products in the Philippine market. First, the Korean Wave image and K-food image were statistically significantly related to the intention to purchase Korean agricultural products. A significant positive (+) effect was found, and when Korean Wave stars were used as variables, the intention to purchase Korean agricultural products was strengthened. Therefore, the results of this study are believed to provide practical implications.

이 연구는 식품제조업과 음료제조업에 속한 1,045개의 기업에 대한 재무제표 패널자료를 이용하여 한계기업으로의 전락에 영향을 주는 요인을 분석하였다. 한계기업의 식별 기준으로 이자보상배율이 3년 연속 1보다 작을 경우를 선택하였다. 패널 프로빗 모형의 추정 결과에 따르면, 개별 기업의 성장성 하락은 한계기업으로 전락할 확률을 높이는 반면, 수익성이나 활동성 지표의 상승은 한계기업으로 전락할 확률을 유의미하게 낮추는 것으로 분석되었다. 또한 타인자본 비중이 늘어나거나 또는 차입금의존도가 높은 기업일수록, 한계기업으로 전락할 확률이 높았다. 기업의 유동성 또한 한계기업으로의 전락 확률에 유의미한 영향을 주었다. 기업 규모도 한계기업 여부와 연관되었는데, 소기업이 대기업에 비해 한계기업으로 전락할 확률이 상대적으로 높았다.

This study was to identify the effects of education on Korean foods preferred by elementary students and their sustainability. A survey was conducted on 5th-grade elementary school students. Korean food preferences were classified by exploratory factor analysis as creative, healthy, or considerate, and the effects of education on Korean dietary life were classified as cognitive or emotional. Dietary life sustainability was evaluated separately. Results showed that creative and considerate preferences had significant impacts on cognitive and emotional education effects and that a healthy preference type significantly impacted the emotional effect of education. Analysis showed that creative and considerate food preference types significantly influenced dietary life sustainability and that cognitive and emotional education effects mediated these relationships. Sex was not found to have a significant moderating effect. The study shows that Korean dietary life sustainability is influenced by education on topics that promote the value and excellence of Korean food and suggests that experiential education combining practice and theory should be used to increase interest in Korean food among elementary students. Additional studies are required to determine Korean food preferences to facilitate the development of a dietary life education program that enables students to understand and maintain healthy dietary practices.

This study summarizes the research methods, subjects, research processes, and achievements of major researchers by analyzing previous research results on Korean food history. The goal of the current study aimed to seek the methodology and direction of ‘food history research’. Literature data from 1945 to 2022 were examined. Results of excavation research on ancient food literature were divided into the following stages: the 1980s, when the foundation for ‘cataloging’ was laid, and the 2000s, when ‘digitization’ was achieved. Achievements of each period were collected, and the achievements and limitations were analyzed. Next, the research results were classified into ‘Food technology history’, ‘Recipe change history’, and ‘Food culture and dietary history’. We observed that around the 2000s, anthropology and folklore research perspectives were reflected, and the research on ‘history of diet’ reached a turning point. Our results indicate the possibility that food history can develop as a special historical area. This could be achieved by establishing an exchange system with other disciplines and creating a systematic curriculum.

Sustainable and healthy diet is a challenge in recent world. Despite the global depletion of water resources, Korea has no system for controlling its water footprint. This study established the water footprint tables of Korean food using the Water Footprint Network databases, and applied them into two meal plans for 19~64 year-old adults recommended in the Dietary Reference Intakes for Koreans 2020. Nut, oil, and meat’s water footprints were higher and those of fruit and vegetable were lower. Sesame oil had the highest water footprint of 21,793 L/kg and pineapple had the lowest domestic water footprint of 102 L/kg. Water footprint of one serving size of beef was 925 L, that of chicken was 260 L, and those of soybean were 43 L in global and 81 L in domestic. The water footprint of the recommended 2,400 kcal meal plan was 2,882 L, and that of 1,900 kcal meal plan was 1,915 L. The water resources can be saved by choosing food with lower water footprint. The results of this study can be used in the further researches for more sustainable and healthier Korean diet.

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”.

This study investigated the trend of research on ‘Food science and Nutrition’ in previously published papers in the Journal of Korean Society of Food Culture (JKSFC) from 2000 to 2021. Total number of published papers in this category in the JKSFC was 693 which we classified into 7 main categories and 40 subcategories. Of these, 256 articles were on ‘experimental cooking’ which was the most studied field among 7 main categories. There was a total of 19 published papers under the category of ‘microbiology and fermentation’. A total of 133 articles were published on ‘functional foods’ and provided essential data for discovering new materials under the theme of various physiological active functions of food materials. Furthermore, 107 articles were included in ‘food processing and storage’, which provided integrated knowledge of economy, stability and practicality based on various technologies. A total of 144 articles was included in the category of ‘nutrition’. Under the category of ‘nutrition’, the most actively studied topic was ‘eating behaviors and dietary habits,’ and the trending topic was ‘use of healthcare big data.’ In conclusion, this review would provide trends of various categories of food science and nutrition area for recent 21 years and suggest directions for future research.

This study was performed to develop a Kdiet-index based on the definitions and characteristics of traditional Korean food. The Korean Food Pattern Index (Kdiet-index) for diseases was applied using dietary data from the 2017 National Health and Nutrition Examination Survey (KNHANES) and the association between Kdiet-index and metabolic disease was confirmed. The study subjects were 1,971 Korean adults aged >40, and the components were classified according to 14 criteria used to establish the Kdiet-index. Main ingredients up to the top 3 were designated using dish names, ingredients, and contents using KNHANES dietary data. Kdiet-index was classified using scores of ≤3 points, 4-7 points, and ≥8 points and total Kdietindex were calculated by summing dietary scores. Correlations between Kdiet-index and obesity, hypertension, hyperlipidemia, and diabetes were analyzed. The odds ratio (OR) and 95% confidence interval (CI) for obesity were 0.531, 0.385~0.732 and for elevated cholesterol (≥240 mg/dL) indices were 0.471, 0.282~0.788, respectively, which showed a significant decreased in the risk for each disease for Kdiet-index of ≥8 points. This study confirms that metabolically related clinical results improved significantly as Kdiet-index increased and that higher Korean food pattern indices are associated with lower risks of metabolic disease

This study reviewed Korean food recipes and food culture included in English cookbooks issued in the United States from the 1930s to the early 1970s. In the 1930s cookbook, many types of soup were introduced to Korean food under the influence of the Tangban culture in the Joseon dynasty and a brief description of ‘Sinseollo’ culture. The 1940s cookbooks, introduced Korean table settings, food culture, and cooking methods depending on the use of chopsticks. In the 1950s cookbooks, Korean foods were selected to suit a Western table setting, and detailed explanations were included along with ‘cheopsu’ means the number of dishes served in Korean food. More diverse Korean food was introduced within its culture and origins in the 1960s cookbooks. The 1970s cookbooks explained, the characteristics of Korean culinary specialties that differentiated from oriental food. This study of Korean food and culture from Cookbooks issued in the United States from the 1930s to 1970s, where Eastern and Western multiculturalism coexist, can be used as baseline data to understand the identity of modern Korean food culture and the direction of the globalization of Korean food.

This study examines the trend of research on food and culture in papers published in the Journal of The Korean Society of Food Culture from 1986 to 2020. The journals published a total of 329 papers, which we classified into 5 main categories and 13 middle categories. Of these, 204 articles were on “Korean traditional food culture.” The most studied topic in the entire period was “Perception of Koreans towards traditional food, preference, satisfaction, and usage.” A total of 76 studies related to “Korean contemporary food culture.” The most advanced topic researched concerned “Recognition and attitude”; these studies were consistently carried out throughout the research period. The main classification of “World food culture” encompassed 32 studies, with major research focused on “World's Modern Food Culture” and the most advanced being “Comparison of Food Cultures of Foreign and Korean Food Cultures.” All studies were consistently spaced out during the study period. These studies provide an integrated knowledge in the field of food and culture and can be used as a basic material for related research in the future.

For any research study, in order to achieve the researcher’s intended purpose, the depth of research is added, and the area of the subject is expanded by clearly defining the scope and objective. The study was undertaken to analyze the bibliographic data of 254 papers in the field of foodservice and restaurant published in the Journal of the Korean Society of Food Culture from 2002 to 2021. The study was divided into two periods: 2002 to 2011, and 2012 to 2021. Research topics were derived and research trends according to temporal changes were confirmed through analysis of keyword networks by period. In addition, analyzing the keyword network of simultaneous appearance of “foodservice” and “restaurant”, the research topics were compared and analyzed in relation to which keywords were expanded by period. Our analysis revealed that the research topics were mostly studied for satisfaction and nutrition. Additionally, they were classified into procurement, Korean food before employee menu, marketing, restaurant industry, and quality. In the period from 2002 to 2011, it was confirmed that studies encompassed a wide range of research topics, focusing on foodservice and restaurant; in the second period from 2012 to 2021, the research topics were more classified and subdivided.

The purpose of study was to examine the factors influencing fast food consumption in Korean adolescents. The analysis was conducted using cross sectional study data from the 16th Korea Youth Risk Behavior Web-based Survey in 2020. A total 54,948 middle and high school students participated in this study. The subjects in the analysis were 28,353 males and 26,595 females, 28,961 middle school and 25,987 high school students. In total, 56.6% Korean adolescents consumed fast food once or twice weekly and 25.4% consumed fast food more than three times weekly. Logistic regression analysis revealed that fast food consumption was significantly associated with dietary behavior such as lower breakfast intake (OR: 0.930, 95%CI: 0.891~0.970, p<0.001), higher soda drinks consumption (OR: 2.563, 95%CI: 2.452~2.678, p<0.001), and higher sweet drinks consumption (OR: 1.898, 95%CI: 1.818~1.982, p<0.001). For psychological and health behavior factors, fast food consumption was also significantly associated with higher perceived stress (OR: 1.239, 95%CI: 1.163-1.321, p<0.001), higher smoking (OR: 1.300, 95%CI: 1.164~1.453, p<0.001), higher drinking (OR: 1.193, 95%CI: 1.112~1.280, p<0.001), higher depression experience, higher loneliness experience, and lower subjective health, In conclusion, fast food consumption in Korean adolescents was associated with undesirable dietary habits and psychological and health behavior, suggesting that appropriate education programs are necessary to reduce such behavior.

본 연구의 목적은 한국 외식기업의 해외시장 진입유형 선택의 결정 요인을 제도이론을 적용하여 검증하는 것이 다. 외식기업에게 중요한 시장지원제도인 지적재산권 보호, 무역 자유, 투자 자유가 진입유형 선택에 어떻게 영향 을 미치는지 분석하였다. 통제와 자원투입 수준에 따라 진입유형을 거래형, 제휴형, 투자형으로 구분하여 순서형 로지스틱 회귀분석으로 검증한 결과는 다음과 같다. 첫째, 현지의 지적재산권 보호 제도가 취약할수록 통제와 자 원투입 수준이 높은 진입유형을 선택하는 것으로 나타났다. 이는 외식기업의 경영 성과에 중요한 지적재산권이 제대로 보호되지 않을 경우 기업은 이를 보호하기 위해 투자 부담이 증가하더라도 통제력이 높은 진입유형을 선 택하기 때문인 것으로 해석된다. 둘째, 무역 자유 제도가 엄격하게 시행될수록 통제와 자원투입 수준이 높은 진 입유형을 선택하는 것으로 나타났다. 외식업은 음식의 맛과 가격이 중요하므로 한국에서와 동일한 맛을 외국에서 구현하기 위해서는 식재료의 반입 가능성과 조달 비용이 매우 중요하다. 따라서 자유무역이 보장되면 필수 식재 료를 한국에서 직접 반출하여 맛과 가격경쟁력을 확보하려는 유인이 작용하는 것으로 볼 수 있다. 이렇게 거래를 내부화 하려는 것은 한식 식재료들이 해외 시장에서 활발하게 거래되는 품목이 아니기 때문에 현지에서 구하기 어려울 뿐 아니라 가격도 매우 비싸기 때문이다. 셋째, 투자 자유 제도에 대한 가설은 유의확률이 높아 채택되지 않았는데, 이는 외식기업의 특성상 마스터 프랜차이즈 계약을 하더라도 본사의 통제력이 상당 정도 확보되기 때 문인 것으로 유추된다. 본 연구는 한국 외식기업이 해외시장에 진출할 때 현지의 시장지원제도에 따라 진입 전략 에 변화를 준다는 것을 실증적으로 규명했다는 점에서 중요한 의미를 갖는다.

The purpose of this paper was to analyze domestic patents for food using edible insects. From January 1, 1980 to December 31, 2021, patents filed with the Korean Intellectual Property Office were searched, and a total of 242 valid patents were selected. The trend of Korean patent applications for edible insect food has increased since 2015, with 57 cases (the highest number) in 2017. As for the edible insects used in food, Bombyx mori L. were the most common with 127 cases, followed by Tenebrio molitor L. with 118 cases. By type of applicant, individuals accounted for the most, with 132 cases. As a result of grouping patents by food classification, 67 cases of edible insects were used in snacks, breads, and rice cakes. As a result of patent analysis, an effort was made to supplement insufficient nutrients by adding nutritionally excellent edible insects to existing foods, and efforts were made to improve the sensory properties of insect foods. It is expected that this study will contribute to establishing future R&D directions and patent application strategies related to edible insect food.
