일반적으로 한국인은 식사를 위해 음식 메뉴를 고를 때 쉽게 결정하지 못하는 비율이 50% 이상으로 높다고 알려져 있다. 이러한 단순 고민 해결을 위해 다양한 음식이나 맛집을 추천해 주는 모바일 앱이나 서비스가 존재한다. 그러나 이들은 사용자가 평소 많이 검색했던 음식이나 맛집들을 위주로 찾아주거나, 랜덤으로 지정된 카테고리 내의 음식들 중 하나를 추천해주는 방식, 혹은 사용자 리뷰 점수가 높은 음식점을 우선적으로 추천해 주는 방식 등을 사용하고 있다. 따라서 기존의 추천 방식은 음식을 추천에 있어 사용자의 의도나 실질적인 연관성이 매우 낮고 평소 먹던 음식의 종류를 크게 벗어나지 않는 경우가 많아 음식 추천이라는 본래의 취지와는 멀어진다. 본 논문에서는 음식 메뉴를 선정하는데 있어 실질적인 영향을 주는 환경 요소인 계절, 기후 등의 날씨 정보를 기반으로 생성형 AI를 통해 적절한 음식을 추천하고 해당 음식을 판매하는 음식점과 그 위치를 알려주는 앱을 개발한다. 개발하는 앱은 바쁜 직장인들이나 매 끼니를 고민하는 학생 등의 메뉴 고민을 해결하는데 도움을 줄 수 있으며, 각종 배달 서비스 앱의 음식 추천 기능의 고도화에 활용될 수 있다.

The purpose of this study is to predict multiplication patterns of foodborne pathogens according to packaging methods and storage conditions in home-delivered meals. Pan fried oak mushroom and meat, soy sauce glazed hair tail and roasted dodok which inoculated $10^6\;CFU/g$ of foodborne pathogens were packaged by wrap packaging, top sealing, vacuum packaging and stored at 25, 4 and $-18^{\circ}C$ during 5 days. The result of study was revealed that the growth and multiplication pattern of the inoculated foodborne pathogens was inhibited in chilling and freezing storage after vacuum packaging, and was significantly influenced by storage temperature. The survival of Listeria monocytogenes was also significantly influenced by storage period. The effective method to preserve the bacteriologic safety of pan fried oak mushroom and meat and soy sauce glazed hair tail in home-delivered meals was stored for maximum three days in chilling storage after vacuum packaging.

This study empirically analyzed the effect of perceived injustice on service recovery measures proposed by online food delivery service (OFDS) companies on consumer disappointment. This study adopted interaction justice, information justice, procedural justice, and distributive justice as sub-variables of justice perception based on the justice theory. In addition, the differences by generation (MZ generation and other generations) were examined in the relationship between negative word-of-mouth behavior and switching intentions due to service recovery failure. An online survey was conducted targeting 250 adult consumers in the U.S for the empirical analysis of this research model. The results of the data analysis demonstrated that negative perceptions about the procedural justice and distributive justice among the service recovery strategies had a positive effect upon the consumer's disappointment. Furthermore, it was confirmed that the consumer's disappointment due to the perceived injustice of the service recovery strategy had a positive effect on the consumer's negative word-of-mouth behavior and switching intentions. The verification results of the moderation effect in the relationship between negative word-of-mouth behavior and switching intention, it was found that the younger the age(MZ generation), the higher the possibility of causing dysfunctional behavior. This study expands the scope of related research by presenting a new perspective on the justice perception in the service recovery process by verifying dysfunctional behavior of consumers caused due to the failure of the service recovery strategy. It is believed that the results of this study will be used as basic data for the establishment of practical strategies for OFDS companies to prevent double defection of their customers.

본 연구는 한국어 자질 기반 감성분석(Feature-based Sentiment Analysis: FbSA)을 위한 대규모의 학습데이터 구축에 있어 반자동 언어데이터 증강 기법(SSP: Semi-automatic Symbolic Propagation)에 입각한 자질-감성 주석 데이터셋 FeSAD(Feature-Sentiment-Annotated Dataset)의 개발 과정과 성능 평가를 소개하는 것을 목표로 한다. FeSAD는 언어자원을 활용한 SSP 1단계 주석 이후, 작업자의 주석이 2단계에서 이루어지는 2-STEP 주석 과정을 통해 구축된다. SSP 주석을 위한 언어자원에는 부분 문법 그래프(Local Grammar Graph: LGG) 스키마와 한국어 기계가독형 전자사전 DECO(Dictionnaire Electronique du COréen)가 활용되며, 본 연구에서는 7개의 도메인(코스메틱, IT제품, 패션/의류, 푸드/배달음식, 가구/인테리어, 핀테크앱, KPOP)에 대해, 오피니언 트리플이 주석된 FeSAD 데이터셋을 구축하는 프로세싱을 소개하였다. 코스메틱(COS)과 푸드/배달음식(FOO) 두 도메인에 대해, 언어자원을 활용한 1단계 SSP 주석 성능을 평가한 결과, 각각 F1-score 0.93과 0.90의 성능을 보였으며, 이를 통해 FbSA용 학습데이터 주석을 위한 작업자의 작업이 기존 작업의 10% 이하의 비중으로 감소함으로써, 학습데이터 구축을 위한 프로세싱의 소요시간과 품질이 획기적으로 개선될 수 있음을 확인하였다.

The purposes of this study were to investigate consumption of home-delivered meals among children from low-income families and to assess their perception of the home-delivered meal service. A survey was conducted on 392 children who had received home-delivered meals, and 208 questionnaires (response rate: 53.1%) were analyzed using SPSS (ver 18.0). The respondents consisted of elementary school students (36.1%), middle school students (33.7%), and high school students (30.2%). Approximately half of children received home-delivered meals during their semester and vacation periods, and 52.2% of respondents shared the delivered meals with their brothers or sisters. Eighty-six point one percent of respondents consumed delivered meals within 4 hours after the meals were received at home, and approximately a fifth of respondents left the delivered meal boxes on a sink counter or table until eating. Leftover foods were kept in the refrigerator (52.2%) or on the sink counter/table (2.5%). The quality of the home-delivered meal service was assessed as 3.3 points based on a 5-point scale. 'Food safety is good' received the highest score (3.62) and 'Food taste is good' received the lowest score (3.07). The results showed that children receiving the home-delivered meal service should be provided information on proper handling and consumption of the delivered meals at home.

The development and generalization of the Internet increased the popularity of food delivery service applications in Korea. The food delivery market based on online-to-offline service is growing rapidly. This study compares the usability of Korean food delivery service application between that of Chinese food delivery service application. This study suggests improvement points for Korean food delivery service applications. To conduct this study, we explore the status of various food delivery service applications and conduct interviews and surveys based on the honeycomb model developed by Peter Morville. This study obtained the following results. First, all restaurants participating in the Korean food delivery service must be able to accept order through the application. Second, the shopping cart function must be able to accept order of all restaurants simultaneously. Third, when users look for menu recommendation, their purchase history and shopping cart functions should appear at the first page of the website. Users should be able to perceive the improved usability of the website using those functions. Fourth, when the search window is fixed on the top of each page, users should be able to find the information they need. Fifth, the application must allow users to find the exact location of the delivery person and the estimated delivery time. Finally, the restaurants'address should be disclosed and fast delivery time should be confirmed to enhance users'trust on the application. This study contributes to academia and industry by suggesting useful insight into food delivery service applications and improving the point of food delivery service application in Korea.

This study examined the mothers' stress level as it related to meal preparation and a change in food consumption during the Covid-19 pandemic. I asked mothers about the difficulties related to meal preparation, changes in food consumption, and their interest in food and health information using in-depth research methods. As a result, food delivery and online food consumption have markedly expanded as eating out has decreased. Mothers tried to serve fresh food at home because they perceived delivery food as unhealthy. They stick to it more vigorously with their younger children. As the result of analysis on determinants of food consumption, their interest in organic food is higher when mothers' ages are younger with higher income. However, mothers with a low level of education tend to be uninterested in it. Therefore, the ages of the children and mothers, household income, and education levels all had an effect on food consumption behaviors.
