최근에는 사회구조가 복잡해 짐에 따라 각 분야의 전문성이 두드러지고 있다. 이러한 흐름은 음식점에도 영향을 주어 기존의 형식에서 벗어난 자신들만의 독특하고 차별성 있는 요리 메뉴의 개발을 가속화시켰다. 그로 인해 한식, 중식, 양식으로 구분하는 전통적인 음식점 분류 방식이 한계를 보였고, 기존의 분류를 포함하면서도 새로이 등장하는 음식점들을 다룰 수 있는 방식이 필요하다. 본 논문에서는 최근 폭발적으로 늘어나는 음식점 추천 웹 사이트의 데이터를 토대로 자동적으로 음식점 분류를 수행하는 방법을 제안한다. 본 연구에서는 각 음식점이 갖고 있는 특징을 메뉴 정보를 통해 파악하려 하였다. 음식점 사이트에서 수집한 2 천개의 음식점, 6 만개의 메뉴 정보를 미리 정의된 필터로 정제한 후 Sequential Information Bottleneck Clustering 알고리즘을 적용하여 구분해 보았다. 실험결과 제안한 방법이 다른 Clustering 방법에 비해 높은 성능을 보였으며 음식점주가 수동적으로 음식점 분류를 입력하는 수고를 줄일 수 있는 가능성을 보였다.

Purpose: The purpose of this study was to measure accessibility and to examine distribution of restaurants in the local community. Methods: The target area of this study was two urban areas and a rural area in a city. We collected location information on all restaurants in target areas and classified all restaurants according to Korean food restaurants and Non-Korean food restaurants. We measured restaurant density per 100 m from the residences of the study population and calculated the distance of the nearest restaurant from the residences of the subjects using the Geographic Information System (GIS) analysis method. We compared the accessibility and distribution of restaurants in urban areas with that of the rural area, and compared the accessibility and distribution of Korean restaurants with that of Non-Korean restaurants. Results: Restaurants in urban areas were more dense than those in the rural area, and, in urban areas, restaurants were intensively distributed around the subjects' residence. Also, there were more Non-Korean food restaurants than Korean food restaurants in urban areas, and it was opposite in the rural area. Conclusion: It is important that we understood the current state of the restaurant environment in the local community using GIS analysis for the first time in the field of food environment. Further research is necessary on the association of restaurant environments and the dietary life of the population.

Purpose: This study analyzed the perception and importance of country-of-origin labeling at restaurants in 500 college students in Jeju surveyed from April 15 to May 5, 2016 with the aim of providing basic data. A total of 465 questionnaires out of 500 were used as base data for this study. Methods: The data were analyzed using descriptive analysis, ${\chi}^2-test$, and t-test using the SPSS Win program (version 21.0). Results: Regarding food safety-related dietary behaviors, average score was 3.65 points (out of 5), and 'put the food in a refrigerator or freezer immediately (4.07)' showed the highest score, whereas 'cool rapidly hot food prior to putting it in the refrigerator (3.08)' showed the lowest score. Regarding the awareness of country-of-origin labeling at restaurants, 67.5% of subjects were aware of it. With regard to dietary behavior of food safety, the high group showed a higher score than the low group (p < 0.001). Regarding reliability of the system, 4.9% of subjects indicated 'very reliable' and 45.4% 'somewhat reliable'. For perception of subject's country-of-origin labeling, the average score was 3.77 (out of 5). Regarding checking country-of-origin labeling at restaurants, 68.0% of subjects checked country-of-origin labeling, and the high group in the safety-related dietary behavior score ranking showed a higher rate (79.3%) than the low group (57.1%) (p < 0.001). With regard to importance by item, 'honest country-of-origin labeling of restaurants' showed the highest score at 4.27 (out of 5). Conclusion: It is necessary to provide continuing education for college students in order to enhance their perception of country-of-origin labeling at restaurants. Moreover, a systematic and appropriate support and control system by the government and local government needs to be developed in order to improve country-of-origin labeling at restaurants.

사람들은 각자 원하는 조건에 부합한 식당과 카페를 찾곤 한다. 그러나 개인별로 원하는 조건들이 다양하고 그 조건들이 모두 부합하는 음식점을 찾기에는 적지 않은 시간과 노력이 필요한 일이다. 이 불편함을 해소하고자, 사용자가 원하는 조건을 입력하면 그 조건에 부합하는 몇 개의 음식점들을 추천해 주고, 지도상으로 위치를 표시해 주는 개인 맞춤형 음식점 추천 시스템을 개발하였다. 본 연구에서 제안하는 추천 시스템은 사용자가 입력한 우선순위에 따라 차별화된 음식점 추천을 받을 수 있으므로, 시간과 노력을 투자하지 않고도 자신이 원하는 음식점을 쉽게 찾을 수 있을 것으로 예상된다.

As review text contains the experience and opinions of the customers, analyzing review text helps to understand the subject. Existing studies either only used sentiment analysis on online restaurant reviews to identify the customers' assessment on different features of the restaurant or network analysis to figure out the customers' preference. In this study, we conducted both sentiment analysis and network analysis on the review text of the restaurants with high star ratings and those with low star ratings. We compared the review text of the two groups to distinguish the difference of the two and identify what makes great restaurants great.

The cleanness of Korean(n=292), Chinese(n=46), Japanese(n=114) and Western(n=74) styles restaurants in 25 districts in Seoul was evaluated in terms of kitchen area(6 criteria), handling of raw materials(3 criteria), hygiene practice for cook(1 criteria), treatment of wastes(2 criteria) and hall(2 criteria). The western-style restaurants were scored the highest points in all criteria. The other three restaurants were poorly evaluated compared with western-style ones in kitchen area, including cleanness of inside of the kitchen, hygiene practice, ventilation and working environment, drainage, and storage of utensils. The most critical criterion which represents the overall evaluation was the ventilation and working environment of the kitchen for Chinese, Japanese and Western-style restaurants, and was the cleanness of inside the kitchen for Korean-style restaurants.

Purpose: The aim of this study was to assess the food environment, particularly focusing on restaurants in three areas (Suwon city, Hwaseong Byeongieom-dong, and Bibong-myun). Methods: A total of 662 persons were surveyed on customers' perceptions of the food environment in restaurants. A structured questionnaire composed of 30 questions on 7 factors, sanitation (4 items), displaying information (5), food quality (12), information on nutritional and healthy food choice (6), restaurant's accessibility (1), availability (1), and affordability (1) was used. In addition, an expert assessment of restaurant sanitation, and information on nutritional healthy food choice was conducted through visiting 126 restaurants. Results: Scores (range of score : 1~7) for each factors assessing the restaurant food environment were 5.06 for sanitation factors, 5.05 for displaying information factors, 5.13 for taste appearance factors, and 4.35 for healthy menu factors. Informations on nutritional healthy food choice showed a low rate: only 16.24% of the subjects answered that there is a message encouraging choice of healthy foods and 27.4% answered that menus contain nutritional information. Significant differences in food environment were observed by region (city, town, rural). The restaurants food environment in the rural area turned out to be poorer than that of the other two areas. In comparison of customer perception and expert assessment, significant differences were observed for 'Employee appearances and uniforms are clean and tidy' (p < .05), and 'There is a message encouraging the choice of healthy foods' (p < .05). Conclusion: This study provided evidence for differences of restaurant food environment by regions. In the rural area, there is a problem in restaurant's accessibility, availability, and affordability because of a lack of variety in menu items and restaurants. This results suggest that there is a need for more healthy food restaurants in the rural area.

Contamination levels of total aerobic bacteria, coliforms, Esherichia coli, Staphylococcus aureus, Bacillus cereus, and Listeria monocytogenes of Kimbab and its main ingredients sampled from general and specialized restaurants were compared. Total aerobic bacteria and coliform counts of Kimbab samples from both restaurant types were not significantly different (p>0.05), showing approximately $4\;to\;6\;log_{10}CFU/g$. E. coli counts were significantly higher in kimbab from general restaurants ($65%:\;0.7-2.6\;log_{10}CFU/g$) than those from specialized ones ($8.33%:\;0.70log_{10}CFU/g$), whereas those of S. aureus and B. cereus were not significantly different (p>0.05). L. monocytogenes was not detected in all Kimbab samples. These results indicate hygiene of Kimbab and its main ingredients are deleterious. Contamination levels of pathogens determined in the present study may be used as primary data for microbial risk assessment.

This study identifies the impact of social network service (SNS) on the spatial characteristics of retail stores locations in the hyper-connected society, which have been closely related to the everyday lives of urban residents. In particular, we focus on the changes in the spatial distribution of restaurants since the information retrieval process was added to the decision-making process of a consumer's restaurant selection. Empirically, we analyze restaurants in Seoul, Korea since the smart-phone was introduced. By applying the kernel density estimation and Moran's I index, we examine the changes in the spatial distribution pattern of restaurants during the last ten years for running, newly-open and closed restaurants as well as SNS popular ones. Finally, we develop a spatial regression model to identify geographic features affecting their locations. As the results, we identified geographical variables and online factors that influence the location of restaurants. The results of this study could provide important groundwork for food and beverage location planning and policy formulation.
