The purpose of the study is to present implications for the management performance and improvement of enterprises through the study of the simplicity of meals, individual values, inhuman relationships, attitude formation, awareness and solitary eating behaviors. The research method was investigated by the judgment sampling method. The collected effective samples were validated using a confirmed factorial analysis to ensure the validity of the discriminatory validity and the internal validity of the convergent validity. First of all, the company should provide information to the people who eat alone to A recognize the simplicity of their meals. Second, we should ensure that the individual values of the Honbab people can be formed through various promotional strategies that can lead to the formation of attitudes. Third, companies should pursue diverse event strategies that can lead to the formation of attitudes of the people of the Honbab family. Fourth, event development such as the provision of a very special service for customers only will have to be conducted when visiting the stores of the Honbap people. Finally, companies should focus on promoting the convenience, convenience, and time-consuming advantages of eating alone through a variety of marketing, and strive to increase their customers.

As the role of online reviews has become increasingly crucial, numerous studies have been conducted to utilize helpful reviews. Helpful reviews, perceived by customers, have been verified in various research studies to be influenced by factors such as ratings, review length, review content, and so on. The determination of a review's helpfulness is generally based on the number of 'helpful' votes from consumers, with more 'helpful' votes considered to have a more significant impact on consumers' purchasing decisions. However, recently written reviews that have not been exposed to many customers may have relatively few 'helpful' votes and may lack 'helpful' votes altogether due to a lack of participation. Therefore, rather than relying on the number of 'helpful' votes to assess the helpfulness of reviews, we aim to classify them based on review content. In addition, the text of the review emerges as the most influential factor in review helpfulness. This study employs text mining techniques, including topic modeling and sentiment analysis, to analyze the diverse impacts of content and emotions embedded in the review text. In this study, we propose a review helpfulness prediction model based on review content, utilizing movie reviews from IMDb, a global movie information site. We construct a review helpfulness prediction model by using an explainable Graph Neural Network (GNN), while addressing the interpretability limitations of the machine learning model. The explainable graph neural network is expected to provide more reliable information about helpful or non-helpful reviews as it can identify connections between reviews.

In response to the COVID-19 pandemic, the global airport industry is actively introducing 4th Industrial Revolution technology-based systems for quarantine and passenger safety, and test bed construction and prior verification using airport infrastructure and resources are actively being conducted. Analysis of recent cases shows that despite the changing travel patterns of airport users and the diversification of airport service demands, most testbeds construction studies are still focused on suppliers, and task prioritization is also determined by decision makers. There is a tendency to rely on subjective judgment. In order to find practical ways to become a first mover that leads innovation in the aviation industry, this study selected tasks and derived priorities to build testbeds from a service perspective that reflects various customer service needs and changes. Research results using the AHP analysis method resulted in priorities in the order of access transportation and parking services (29.2%), security screening services (23.4%), and departure services (21.8%), and these analysis results were tested in the airport industry. It shows that innovation in testbeds construction is an important factor. In particular, the establishment of smart parking and UAM transportation testbeds not only helps strengthen airports as centers of technological innovation, but also promotes cooperation with companies, research institutes, and governments, and provides an environment for testing and developing new technologies and services. It can be a foundation for what can be done. The results and implications produced through this study can serve as useful guidelines for domestic and foreign airport practitioners to build testbeds and establish strategies.

Today, researches on logistics service quality or supply chain management are highlighted due to intensification of competition and diversification of needs for customer service. This study have done a comparative analysis on supply chain partnership members' perception difference about importance of logistics service quality factors. It measured perception about logistics service quality which suppliers, carriers, and buyers regard as important and then conducted t-test in order to compare perception difference. It was found that quality factors of logistic service which suppliers, carriers, and buyers in supply chain partnership perceive as important were different. And disagreements among members were found in most items when market orientation and long term orientation was low while there was no difference among most members when market orientation and long term orientation was high.

The most widely used data mining technique is to explore association rules. This technique has been used to find the relationship between items in a massive database based on the interestingness measures such as support, confidence, lift, etc. Association rules are frequently used by retail stores to assist in marketing, advertising, floor placement, and inventory control.In general, association rule technique generates the rule, 'If A, then B.', whereas negative association rule technique generates the rule, 'If A, then not B.', or 'If not A, then B.'. We can determine whether we promote other products in addition to promote its products only if we add negative association rules to existing association rules. In this paper, we proposed the negatively attributable and pure confidence to overcome the problems faced by negative association rule technique, and then we checked three conditions for interestingness measure. The comparative studies with negative confidence, negatively pure confidence, and negatively attributable and pure confidence are shown by numerical examples. The results show that the negatively attributable and pure confidence is better than negative confidence and negatively pure confidence.

귀농귀촌 문화가 유행하고 농업의 미래 가치에 대한 인식이 변화되면서 농산업으로의 새로운 진출을 계획하는 인구가 늘고 있다. 우리의 농업은 자급자족경제로부터 상업경제로 발전되어 왔고, 글로벌 시장 개방 및 생산 기술의 지속적 발전으로 공급이 수요를 초과하며 가격이 점점하락하는 추세를 보이고 있다. 농업 현장의 여러 어려움에도 불구하고 농산업의 긍정적인 여건들도 형성되고 있다. 올바른 먹거리를 추구하는 식품 소비패턴의 변화, 환 생태 치유 자연에 대한 소비자의 관심고조, 스마트 팜과 같은 생산환경의 자동화, 지역 자원을 근거한 공동경영체 운영 등과 같은 현상이 두드러지게 나타나고 있다. 이러한 시점에 농산업분야에 새로이 진출하고자 하는 개인 또는 소규모 사업주체들은 자신의 사업에 대한 정체성을 이해하고, 효율적인 사업운영을 위한 차별화 전략을 확보할 필요가 있다. 본 연구는 개별 또는 소규모 조직의 농업인과 예비농업인들이 자신의 사업에 대한 정체성을 이해하고, 사업운영을 위한 전략 선택을 돕는 비즈니스모델 템플릿 개발을 목표로 하였다. 이를 위해 농업 전문가, 창업 전문가, 비즈니스모델 전문가 풀을 구성하여 농산업 특성을 이해하고 최근 농업 농촌에서 이슈가 되고 있는 농업비즈니스 트랜드를 분석하였다. 근거 자료 및 전문가 토론을 통해 농산업 비즈니스를 '시장가치 추구형', '사회적가치 추구형', '연대하는 시장가치 추구형', '연대하는 사회적가치 추구형'의 4가지 유형으로 구분하고, 각 유형별 사례기업을 조사하여 비즈니스모델을 분석하였다. 비즈니스모델은 비즈니스모델 젠 캔버스를 이용하여 표현하였다. 비즈니스모델 젠은 비즈니스 유형에 따라 일반 창업형, 협동조합형, 임팩트비즈니스형 등 차별화된 캔버스 모델을 제공하고 있으며, 고객중심의 비즈니스 관점을 보다 세밀히 제공하는 툴이다. 본 연구에서는 비즈니스모델 젠을 통해 4가지 유형의 농산업 비즈니스 모델을 분석하였다. 본 연구의 결과는 농산업에 진출하는 사업주체의 사업진행 방향 및 전략선택을 위한 교육 컨설팅 현장에서 널리 이용될 수 있을 것으로 판단된다.

국내 항만공사는 항만공사법이 2003년 제정되고 부산항만공사가 2004년 설립된 이후 인천항만공사, 울산항만공사, 여수광양항만공사가 설립되어 운영되고 있다. 그러나 항만공사의 운영이 비효율적인 방향으로 흘러감에 따라 정부를 중심으로 공기업 통 폐합 등의 조직 개편 움직임의 목소리가 나오고 있다. 정부에서 구상하는 개편 방안 중 항만관리에 대해 통합적 운영이 적절한지, 분권적 운영이 바람직한지에 대해 보다 심층적인 논의가 필요하다. 본 연구는 항만공사 운영방식 개혁에 대한 논의에 대비하여 이러한 통합적인 접근방식과 분권적인 접근방식에 대한 비교분석을 하는 것을 그 목적으로 한다. 이를 위해 항만공사제도의 도입배경과 현황, 조직의 통합운영과 분산운영에 대한 이론적 배경, 국내 공기업 통합 사례 및 해외항만 운영 사례, 항만공사 운영 방식의 대안별 비교를 실시하였다. 이를 통해 다음과 같은 결론을 얻을 수 있었다. 첫째, 항만공사제도는 기존의 항만관리제도 개선을 위한 노력이라는 역사적 맥락을 기반으로 하여 기존 관리제도의 문제점을 개선하기 위한 대안으로 도입된 제도이며, 이러한 제도적 목적을 기반으로 항만공사 운영개선방안 논의가 되어야 한다는 것이다. 둘째, 공공기관 운영에 있어 내재되어 있는 문제점을 개선하기 위해 기관통합, 기능 조정, 부분통합 등 다양한 방식으로 개선이 가능하며 반드시 하나의 방법으로 이루어 질 수는 없다는 것이다. 셋째, 해외 주요 항만의 경우 개별 항만에 항만공사를 운영하는 개별적 운영방식을 택하고 있으며 대만이 유일하게 통합 운영하는 방식으로 개편하였으나 그 통합으로 인해 기대하는 효과가 실현되고 있지 않아 통합운영 방식의 근거가 되기는 어렵다. 넷째, 항만의 운영 자료를 분석한 결과 항만별로 처리하는 화물과 선대의 특성이 차이가 나고 운영방식과 대상이 되는 시장이 다름을 알 수 있었다. 이러한 항만별 운영과 고객의 차이를 감안하면 개별적 운영방식이 바람직하다고 판단된다. 결과적으로 통합 운영방식의 운영 효율성 개선 효과가 있을 수 있음에도 불구하고 항만공사제도의 목적과 취지를 감안할 때 현행 개별운영 방식을 유지하는 것이 바람직하다는 결론을 제시한다.
