The study was carried out to develope quantitative analysis method of individual sugars in licorice extract. Individual sugars were analyzed by HPLC equipped with Refractive Index(RI) Detector. R values of sucrose and glucose were 1.0000 and R values of fructose and maltose were 0.9999. Standard calibration curve showed good linearity. Detection limit of sugars was in the range of 1.58 to 3.92 ${\mu}g$. Recovery rate of fructose, glucose, sucrose and maltose was $99.4\~102.2\%,\;92.3\~97.9\%,\;99.4\~102.0\%,\;91.1\~101.0$ respectively. Measure uncertainty was calculated to confirm trust and accuracy of analytical results. Main uncertainty factors were standard purity and HPLC replication injection. In $95\%$ trust level expanded uncertainty of sugars in licorice extract were fructose $1.98\pm0.047,\;glucose\;1.32\pm0.065,\;sucrose\;11.69\pm1.177,\;maltose\;1.06\pm0.042\;g/100\;g$.

As the number of services available on the Web increases, it is vital to be able to identify which services can be trusted. Since there can be an extremely large number of potential services that offer similar functionality, it is challenging to select the right ones. Service requestors have to decide which services closelysatisfy their needs, and theymust worry about the reliability of the service provider. Although an individual service can be trusted, a composed service is not guaranteed to be trustworthy. In this paper, we present a trust model that supports service discovery and composition based on trustworthiness. We define a method to evaluate trust in order to discover trustworthy services. We also provide a method to perform trust estimation for dynamic service composition, and we present results of two experiments. The proposed model allows for service requestors to obtain the most trustworthy services possible. Our mechanism uses direct and indirect user experience to discover the trustworthiness of the services and service providers. Moreover, composing services based on quantitative trust measurements will allow for consumers to acquire a highly reliable service that meet their quality and functional requirements.

This study aims to determine the behavior of consumer interest in sustainable fashion products in Indonesia and the factors that influence it. Personal values, Green Trust, and attitude toward green products are studied to get a proper picture of the ethical behavior of consumers. The method used is the Structural Equation Model (SEM) technique using AMOS 23 software. A sample of 103 participants used the convenience sampling technique. The study results show that green trust and attitude toward green products successfully mediate personal value and green purchase intention on ethical fashion products in Indonesia. In this study, it was found that personal values cannot directly influence the purchase intention of sustainable fashion products. The influence of Personal Value must first be mediated by green trust or attitude toward green products to further influence green purchase intention of ethical fashion products in Indonesia. This is not in line with previous studies. Indicators of personal values such as self-transcendence, self-enhancement, conservation, and openness directly cannot predict the behavior of purchase intentions for sustainable fashion products in Indonesia. From the descriptive conclusion of the data obtained, there are various types of meanings of individual values, and fashion consumers in Indonesia are more affected by contextual factors.

Purpose Since COVID-19, the demand for online class platforms has increased. However, those platforms have not been clearly defined, and related research is also limited. In the context of the knowledge marketplace (KMs), this study examined the effects of class information and trust in creators on class preferences from the perspective of consumption value theory. Design/methodology/approach By establishing a web crawler through Python, this study collected 1,174 class data in Korea's leading knowledge marketplace, Class 101, focusing on diverse class-related information and the number of Instagram followers for individual class creators. Based on class information, this research analyzed the effects of consumers' utilitarian value, social value, and hedonic value on class preference. In addition, this study examined whether consumers' trust in creators moderates the relationship between class information and class preference. Findings According to analysis results, it was found that the higher the consumers' consumption value for each class on KMs, the more positive their preference for the class. Also, it was confirmed that consumers' trust in creators moderates the relationship between class information and class preference.

Purpose - This study examined the effect of perceived corporate social responsibility (CSR) on cognitive trust, emotional trust, and loyalty among using Korean food buffet franchises. The result of this study is expected to provide practical implication to industry practitioners in expanding their understanding of the CSR effect in the marketing perspective. Research design, data, and methodology - The data was collected from a panel of online research companies who are over 20 years old and dined in at Korean style buffet franchise outlets more than five times. A total of 370 samples were used after eliminating outliers and missing data. the data were analyzed SEM with SPSS and AMOS. Result - The result of this study showed that: 1) social CSR activities have an effect only on emotional trust; 2) food-related CSR activities influence both cognitive trust and emotional trust; and 3) both cognitive trust and emotional trust have a significant impact on customer loyalty in Korean style buffet franchises. However, it is important to note that this study found no significant causal impact from environmental CSR activities. Furthermore, this study found that food-related CSR activities have the greater influence on the cognitive trust, and cognitive trust is more influential on the customer loyalty than the emotional trust. Conclusions - Based on the findings, this study provides practical implications to industry practitioners. First, that CSR has a significant impact on customer trust suggests that Korean style buffet franchises should focus on CSR activities to improve customer trust. Second, that food-related CSR activities have the greater influence on the cognitive trust implies that industry practitioners should reinforce food-related CSR activities as a marketing tool to enhance emotional trust and the overall credibility of their franchise. Third, we need to find CSR measures at the social level that can secure emotional trust so that customer loyalty can be formed. Fourth, Korean food buffet franchise food service companies should concentrate their efforts on CSR activities at food and social level among the three dimensions suggested by researchers in order to form customer loyalty. For next study, perceived concept of CSR on individual customer should be examined.

This study investigates the perception and adoption of ChatGPT (a large language model (LLM)-based chatbot created by OpenAI) among Korean users and assesses its potential as the next disruptive innovation. Drawing on previous literature, the study proposes perceived intelligence and perceived anthropomorphism as key differentiating factors of ChatGPT from earlier AI-based chatbots. Four individual motives (i.e., perceived usefulness, ease of use, enjoyment, and trust) and two societal motives (social influence and AI anxiety) were identified as antecedents of ChatGPT acceptance. A survey was conducted within two Korean online communities related to artificial intelligence, the findings of which confirm that ChatGPT is being used for both utilitarian and hedonic purposes, and that perceived usefulness and enjoyment positively impact the behavioral intention to adopt the chatbot. However, unlike prior expectations, perceived ease-of-use was not shown to exert significant influence on behavioral intention. Moreover, trust was not found to be a significant influencer to behavioral intention, and while social influence played a substantial role in adoption intention and perceived usefulness, AI anxiety did not show a significant effect. The study confirmed that perceived intelligence and perceived anthropomorphism are constructs that influence the individual factors that influence behavioral intention to adopt and highlights the need for future research to deconstruct and explore the factors that make ChatGPT "enjoyable" and "easy to use" and to better understand its potential as a disruptive technology. Service developers and LLM providers are advised to design user-centric applications, focus on user-friendliness, acknowledge that building trust takes time, and recognize the role of social influence in adoption.

The purpose of this study is to review the relationship between transformational leadership(charisma, individual consideration, intellectual stimulation, inspiration) and knowledge management, and the moderating effect of social(trust and interaction) in small business. In order to verify and achieve the purposes mentioned above, questionnaire data are gathered and analysed from 311 subjects in Kangwon-do province. Multiple regression and multiple hierarchical regression analysis were applied to test these hypotheses: 1) the relationship between transformational leadership and knowledge management, 2) the moderating effect of trust on the relationship between transformational leadership and knowledge management, 3) the moderating effect of interaction on the relationship between transformational leadership and knowledge management. Empirical survey's findings are as follows; First, individual consideration and inspiration leadership appeared to be positively related with all knowledge management(knowledge creation, transfer, application). Second, charisma was verified to be positively related with knowledge creation only. Third, charisma and inspirational leaderships were more positively with knowledge creation in higher trust group than in lower trust group. Fourth, intellectual stimulation and inspirational leaderships were more positively with knowledge creation in higher interaction group than in lower interaction group. Fifth, individual consideration was more positively with knowledge application in higher interaction group than in lower interaction group.
