The consumption of ready-to-eat side dishes is rapidly growing in South Korea. These foods are particularly vulnerable to microbiological contamination as they are often cooked without any treatment, such as heating or stored at room temperature after cooking. Hence, in 2022, we analyzed the ready-to-eat side dishes sold in Gyeongsangnam-do, South Korea for microbiological contamination. We collected 100 samples from supermarkets in 7 cities, and then examined them for presence of food-borne pathogens and sanitary indicator bacteria. In the analysis of the food-borne pathogens, Bacillus cereus and Clostridium perfringens were isolated from 51 samples (51.0%) and 3 samples (3.0%), respectively. However, both quantitatively met the Korean Food Standards Codex. Genes of five different enterotoxins and one emetic toxin were analyzed from the 51 isolated B. cereus strains. We detected enterotoxin entFM (100.0%), nheA (94.1%), hblC (58.8%), cytK (56.9%), and bceT (41.2%) in 51 isolates, and emetic toxin gene, CER, in only one (2.0%) isolate. We did not detect C. perfringens toxin gene (cpe) that causes food poisoning in any one of the three C. perfringens isolates. In the case of sanitary indicator bacteria, Kimchi had the highest levels of total aerobic bacteria and coliforms, followed by Saengchae, Jeotgal, Jeolim, Namul, and Jorim, respectively. We counted total aerobic bacteria at two different storage temperatures (4oC and 20oC) to determine the effect of storage temperature. When stored at 20oC, total aerobic bacteria count increased in most of the ready-to-eat side dishes, except for Jeotgal. This result conclusively shows the need for refrigerating the ready-to-eat side dishes after purchase. Further research is needed to assess the risk and safety of the ready-to-eat side dishes available in the market and determine appropriate safety management practices.

The costs associated with law enforcement have seen a sharp increase, driven by rising personnel costs and the growing demand for policing services (Gascón, 2010; Urban Institute, 2020). Considerable discussion has arisen about how science can potentially help law enforcement “do more with less”, and some scholars have suggested introducing new crime control technologies to address this problem (e.g., Roach, 2022; Weisburd & Neyroud, 2011). With the onset of the COVID-19 pandemic, police departments around the world had additional demand, as they were made responsible for overseeing and ensuring compliance with COVID protocols. As a response, some countries (e.g., Singapore and China; Barrett, 2021) resorted to employing service robots either alongside or in place of police officers to assist with COVID-related compliance tasks.

The popularity of live streaming is driving the emergence of a new business model, known as live-streaming commerce (LSC). While there are more and more broadcasters in LSC, their behaviors and performance of them are significantly different. To have a better understanding of broadcasters, we employ different machine learning models to identify different portraits in both static and dynamic dimensions. We collect a rich live-streaming dataset from one leading platform in China. Our dataset features information for both broadcasters and viewers, including viewers’ purchasing behaviors, viewers’ records of posting words, broadcasters’ gender, the number of followers for broadcasters, and the live streaming show information, including the start and end time, and the viewers in each live streaming show. The rich textual information in broadcasters’ profile induction provides us a good opportunity to uncover different static portraits and the records in live streaming shows give us a chance to identify different dynamic behavioral portraits for broadcasters.

Artificial intelligence (AI) is transforming healthcare, yet little is known about how consumers experience and make decisions regarding follow-up care with medical AI. We take an interdisciplinary approach combining behavioral research and neuroscience to examine how anthropomorphism and personalization influence well-being and follow-up decisions. Study 1 found that consumers felt well-being after interacting with a highly personalized interaction, whether human or AI doctor. However, they preferred follow-up visits with the human doctor. Empathy mediated these effects. Study 2 used fMRI to show that the anterior cingulate cortex had greater activation when interacting with the human doctor, indicating more emotional processing and conflict resolution. These findings suggest that medical AI cannot currently replace human doctors, who remain vital for actual medical consultations and treatment. However, consumers viewed AI doctors positively and expressed a belief that AI will enhance well-being. By integrating neuroscience, this research provides biological evidence complementing behavioral findings.

In recent business activities, well-being-based management approaches have become increasingly important. Consideration of consumer well-being is one of them. In particular, social demand and interest in health are incredibly high, and the health-related services market has significantly expanded. However, since the WHO's definition of health was established, the concept of health has become multi-dimensional. There is much overlap with other concepts, such as well-being and quality of life. As a result, even for health-related services that are supposed to contribute to consumers' health, the critical term "health" is still used ambiguously by both service providers and consumers. It could increase the uncertainty of the benefits of the services and cause difficulties in the continued use of services for consumers.

Recently, the luxury sector has witnessed a significant rise in luxury consumption, reaching £233 Billion in 2022 (Statista, 2022). This rise demonstrates the growing popularity of the luxury consumption phenomenon globally. However, the climate crisis may impact future trends in luxury consumption (Gardetti and Muthu, 2019). The luxury sector has endorsed a considerable growing demand for sustainability from environmental and ethical luxury consumers. In recent years, concerns have grown around the ethicality of supply chains, where consumers develop contradictory feelings and beliefs, veering between conscious and hedonistic decision-making (Kleinhaus, 2011; Helm, 2020; Wang et al. 2021). Moreover, consumers face a conflict between choosing what they believe is ethically right and indulgence (Hennigs et al. 2013). The supply chain plays an important role in achieving sustainability goals, and yet some researchers argue that the luxury supply chain can involve ethical and environmental breaches in terms of labour and raw materials, such as use of leather and fur (Klerk et al. 2018). However, some luxury brands such as Stella McCartney and Vivienne Westwood are focused on sustainability and the use of vegan raw materials (YNAP, 2021).

This paper tests firms’ strategic response to negative consumer sentiment. We use sentiment analysis on social media posts to detect and proxy for negative consumer sentiments toward the firms and operationalize the number of ESG positive news about the firms as the strategic response to the sentiment. We document a surprising phenomenon that negative sentiment toward a firm is positively associated with future ESG news announcements by the firm. The effect is stronger for B2B firms than for B2C ones. We argue this is the firm’s strategic reaction rather than being a true change in the firm’s ESG policy, because (1) The ESG effect only lasts for a short period, and (2) the negative sentiment toward the firm decreases after the ESG news. Using former US president Trump’s tweets as external shocks, we show the causal relationship in a DID framework.

Virtual reality (VR) has been set with an expectation of becoming the technology to enable new electronic businesses on metaverse platforms. VR is an application of three-dimensional computer graphics to create a convincing virtual environment where users can interact (Cowan & Ketron, 2019). The most used immersive VR devices are head-mounted displays. Importantly, in addition to visual sense, auditory, haptic, and olfactory senses stimulating devices are used in conjunction with head-mounted displays to reach a multi-sensory VR experience (Xi & Hamari, 2021). VR has been part of the brand strategy for various marketing endeavours (Cowan & Ketron, 2019) such as viewing furniture or kitchen setups by IKEA or creating virtual customer experiences in the real estate sector. However, VR’s impact on the consumer thought model has not been thoroughly examined. This extended abstract contributes to this shortcoming.

This study aims to empirically investigate how corporate strategy mitigates consumer boycotts caused by animosity toward economic sanction. First, the study focuses on the cross-culture emotions (i.e., animosity and affinity) and explores the direct and indirect effect of animosity toward economic sanction on boycott attitude (via consumer affinity). Additionally, it focuses on the moderating effect of brand strength and corporate social contribution on boycott attitude. We conduct a longitudinal analysis of boycotts by South Koreans on the Japanese products, which started in South Korea in 2019; and additionally, we employ PROCESS macro to test the moderated mediation hypothesis, using the data collected from South Korea in 2020 and 2021. Our findings reveal that the data collected in 2020 and in 2021 have the same implications. The main findings are as follows. First, while animosity toward economic sanction directly increases boycott attitude, it also indirectly increases boycott attitude via consumer affinity. Second, the assumption that both brand strength and corporate social contribution weaken the positive and direct effects of animosity toward economic sanction on boycott attitude was not supported. Third, we find that corporate social contribution weakens the positive and indirect effect of animosity toward economic sanction on boycott attitude. However, unlike our prediction, brand strength strengthens the positive and indirect effects of animosity to economic sanction on boycott attitude. The three key theoretical implications are as follows. First, while many studies have examined the role of animosity as a cause of boycott, only a few studies have simultaneously addressed the conflicting emotions of affinity (Kim, Yan, Kim, Terasaki, & Furukawa, 2022). This study extends boycott research by exploring the relationship between animosity and boycott attitudes by considering the mediating effect of affinity. Second, to our best knowledge, only a few boycott studies have explored corporate strategies that adequately respond unanticipated country boycotts where the companies are not directly associated with the causes or motives of such boycotts (Kim & Kinoshita, 2023). This study extends boycott research by investigating brand strength and corporate social contribution as corporate strategies in the context of consumer boycotts. Third, although it is known that consumer boycotts change with time, only a few boycott studies are based on longitudinal analyses (Ettenson & Klein, 2005); hence, this study examines consumer boycotts longitudinally to improve the generalization of our findings. Our findings also present some managerial implications for global companies facing unexpected country boycotts by local consumers. When boycotts are caused by economic sanctions between countries, brand strength exerts a two-sided effect. Regarding consumer sentiment, the higher the brand strength, the higher the affinity for the country represented by the brand, and vice versa; however, consumers may also choose to boycott a brand with high strength. Consumers may feel angry and engage in boycotts when they feel betrayed by a brand with strong brand strength. However, corporate social contribution reinforces a sense of closeness in the country it presents and contributes toward mitigating the boycott attitude; this is because consumers consider their corporate social contribution as a beneficial activity for their country. Therefore, global companies that expand overseas should not only use their brand strength, but also engage in activities that are beneficial to the country and enhance the familiarity of the consumers of the country to develop a sense of cultural affinity. In addition, this study also has implications for policymakers. Economic sanctions against a specific country not only lower consumers’ affinity, but also leave a negative impact on the global companies with high brand strength. Therefore, policymakers must proceed with caution when they make an economic sanction for a certain country.

본 연구는 가상현실 지질학습장을 개발하여 학교 현장에서 겪는 어려움으로 인해 소홀히 여겨지는 야외 답사를 대체하는 방안을 찾고자 하는 데 목적이 있다. 이를 위해 교육과정 내용 요소와 가상현실 개발 가능성을 검토하여 적 상산 일대를 중심으로 총 5곳의 지질학습장을 선정하였다. 가상현실 지질학습장은 학생들이 주도적으로 가상의 공간에 서 암석과 지질구조를 관찰하고 탐구할 수 있도록 구성하였으며, 구상화강편마암, 응회암, 역암, 사암, 층리, 절리 등 학 습 요소를 포함하였다. 개발한 학습장이 갖는 교육적 가치를 알아보고자 중학교 1학년 학생 7명에게 적용하고 반-구조 화된 면담을 실시하였으며, 학생 반응 결과를 언어 네트워크를 이용하여 단어 간 의미 있는 관계를 분석하였다. 그 결과로 학생들은 가상현실일지라도 현실감을 느낄 수 있었으며, 이는 곧 암석의 특징을 이해하고 기억하는 데 긍정적인 영향을 주고 있었다. 이는 가상현실 야외지질학습 프로그램을 통해 야외에서 이루어지는 현실감을 학생들에게 간접적으 로 경험하게 함으로써 학습에 긍정적인 영향을 줄 수 있음을 시사한다. 본 연구를 바탕으로 무주군이 지닌 지질 학습 자원이 가상현실을 통해 학교 현장에서 유의미한 학습 자료로 활용되기를 기대한다.

견과류는 영양가가 우수하고 다양한 기능성 생리활성을 가져 건강한 식단에 중요한 요소이다. 멜라토닌은 뇌의 송 과선에서 분비되는 호르몬으로 각종 조직의 산화적 손상을 방지하는 것으로 알려져 있으며, 식물체에서도 중요한 역할 을 한다. 본 연구는 견과류의 멜라토닌 추출 및 정량을 위 한 분석법을 마련하였고, 견과류의 높은 지방함량을 고려한 최적화된 추출 절차를 이용하여 경기도에서 유통되는 견과 종실류 등의 멜라토닌 함량을 조사하였다. 땅콩 또는 견과 류, 유지종실류 및 두류의 평균 멜라토닌 함량은 각각 1200.83 (409.76-2223.56), 934.83 (454.10-1736.60), 616.46 (494.70- 825.12) pg/g으로 나타났다. 호두와 밤의 경우 속껍질을 포 함한 반탈각 상태와 과실만 있는 경우의 멜라토닌 함량을 비교한 결과, 반탈각 상태에서 멜라토닌 함량이 유의적으로 높았다. 또한 호두, 밤 및 땅콩의 경우 2022년 재배된 햇 견 과보다 2021년 재배 후 저장된 견과에서 멜라토닌 함량이 유의적으로 높았다. 이러한 결과는 견과종실류 등의 멜라토 닌 함량이 높아 우수한 기능성 식품임을 시사하였다.

본 연구에서는 경기도 내 유통 중인 견과 종실류의 잔 류농약 실태를 조사하고자 온라인 또는 유통매장을 통해 131건을 수거하여 조사하였다. 총 14품목의 견과종실류 를 수거하였으며 339종의 잔류농약을 분석한 결과 131건 중 총 8건에서 검출되었으며 범위는 0.01 mg/kg-0.07 mg/ kg 수준으로 나타났다. 검출된 시료 8건 중 7건이 잔류 농약 기준을 초과하여 부적합으로 판정되었으며 부적합 7건 중 6건은 수입농산물에서 판정되었다. 중국산 호박씨 의 경우 PLS가 적용된 피라클로스트로빈이 5건 검출되 었으며 범위는 0.02 mg/kg-0.04 mg/kg 수준으로 나타났다. 인도산 참깨와 국내산 참깨에서도 펜디메탈린, 보스칼리 드, 비펜트린이 각각 0.04 mg/kg, 0.05 mg/kg, 0.06 mg/kg 으로 검출되어 부적합 수치를 보였다. 또한 검출된 8종 의 농약에서 EDI/ADI (%) 값이 0.002%-0.372%으로 낮 은 수준임을 확인하였다.

In this study, sustainable utilization plans were proposed by reviewing the current status and problems of water infrastructure, focusing on water supply and sewage system in Chungcheongnam-do. Due to the regional characteristics of the rural areas in Chungcheongnam-do which has a very low urbanization rate, there is a difference in the level of water welfare services between local governments. Compared to other governments, there are relatively many small water facilities, resulting in a service imbalance in terms of tap water safety. In addition, Chungcheongnam-do has a structure that is very vulnerable to water security to cope with climate change and drought due to its high dependence on wide-area water supply. Therefore, it should be considered in consideration of population reduction and local extinction due to low birth rate and aging population. Rural areas should clearly establish marginal areas for the supply of water and sewage, and implement regional customized water and sewage projects in consideration of local extinction. Water supply projects should be implemented in a distributed water supply method using various water sources. In order to respond to climate change and establish water security, a distributed water supply system should be established through a multi-source water loop system using various water sources. Sewage projects should be establish public sewage treatment facilities in consideration of the priorities of each local government, focusing on local governments with low sewage treatment population rates. In consideration of regional characteristics, it is necessary to consider the installation of private sewage treatment facilities or nature-friendly treatment facilities such as soil infiltration and artificial wetlands. An integrated management system using Internet of Things(IOT) or Information and Communications Technology(ICT) should be established and operated to improve the operation and management efficiency of small-scale water supply and sewage facilities.

2022년 4월에 군형법 제92조의 6 추행죄에 관하여 나온 대법원 전원합의 체 판결(2019도3047)은 법학방법론적으로 다양한 문제지점들을 담고 있어 서도 관심을 끈다. 그 판결에서 다수의견과 별개의견들 및 반대의견은 적용 법조항의 의미를 두고서 전통적인 법학방법론의 네 가지 방법인 문언, 체계, 역사, 목적은 물론 법해석과 법형성의 구별 및 허용되지 않는 법형성, 헌법합 치적 해석과 헌법정향적 해석, 그리고 법해석 일반론에 이르기까지 상이한 의견을 제시하였다. 특히 다수의견이 법원의 법해석권한을 넘어서 국회나 헌 법재판소의 권한을 침해하는지가 명시적으로 다투어진 점은 법원의 법해석권 한의 한계에 관한 관심을 불러일으켰다. 이 연구에서는 이 판결을 법학방법론상 다음과 같이 분석하고 평가하였다. 1. 문언해석의 차원에서 군형법 추행죄에서 대표적인 예시적 구성요건인 ‘항문성교’는 이성 간에도 가능한 일상적 의미가 아니라 남성 간의 행 위를 가리키는 일종의 전문용어로 해석하는 것이 동 조항의 입법의도를 포함한 역사적 맥락에 부합한다. 이 판결의 다수의견은 이와 달리 그 단어를 일상적 의미로 해석해서 항문성교의 대표적인 예시적 구성요건 으로서의 의미를 탈각시키고 소극적 구성요건을 창설하였다. 법문언에 반하는 이러한 목적론적 축소해석은 민주적 법치국가에서 재판의 법률 구속성 요청에 따르는 엄격한 정당성 심사를 받아야 한다. 2. 체계적, 목적론적 해석의 차원에서 동 조항의 보호법익으로 군기 이외 에 성적 자기결정권을 포함시킨 다수의견은 군형법과 형법의 체계에 맞 지 않다. 3. 역사적 해석의 차원에서 다수의견은 입법자의 의사를 지나치게 경시하 였다. 4. 입법자의 의도에 반하는 법해석 또는 법형성의 정당성은 예외적으로만 인정될 수 있다. 국회의 입법권과 헌법재판소의 위헌법률심판권을 침해 하여 법치국가원리를 침해하기 때문이다. 이 판결 다수의견의 법형성은 그러한 예외적 정당성이 인정되는 경우가 아니다. 5. 헌법합치적 해석은 헌법의 기본권 조항들 뿐 아니라 민주적 법치국가의 권력분립존중 요청에도 부합하게 이루어져야 한다. 이 판결 다수의견은 그런 요청에 부합하지 않아서 헌법합치적 해석으로 타당하지 않다. 결론적으로 이 판결의 다수의견과 별개의견들은 민주적 법치국가 원리에 따라서 존중해야 하는 국회의 입법권과 헌법재판소의 위헌법률심판권을 침해 하여 부당하다.
