Art in the modern sense takes the lead to reform the society through constant interaction with members in society. Therefore the works of Art should be understood as social compositions that are reconstructed creatively according to the social environmental impact. Recording, collecting and preserving the references are compulsory for the constant social reform, so the importance of Archive is stressed. However, the Art Archive in Korea is operating very limitedly just to provide simple references to the users. Thus, We need to seek for various ways and user-focused service to utilize the digitalized Art culture records, and need positive research on Art Archive to enhance the creative activities. So in this study, we subdivided the interactivity and applied TAM model. Our analysis on the effect on the purpose of use shows that the users need to be provided with useful informations easily for their creative activities. It also shows that the purpose of use increases through awareness of interactivity. However, the result of this study has a limit of the sample so further studies for the purpose is suggested.

Purpose Despite the recent increase in the use of selection tools using artificial intelligence (AI), far less is known about the effectiveness of them in recruitment and selection research. Design/methodology/approach This paper tests the impact of AI-based initial screening and interview on intentions to apply. We also examine the moderating role of individual difference (i.e., reliability on technology) in the relationship. Findings Using policy-capturing with undergraduate students at a large university in South Korea, this study showed that AI-based interview has a negative effect on intentions to apply, where AI-based initial screening has no effect. These results suggest that applicants may have a negative feeling of AI-based interview, but they may not AI-based initial screening. In other words, AI-based interview can reduce application rates, but AI-based screening not. Results also indicated that the relationship between AI-based initial screening and intentions to apply is moderated by the level of applicant's reliability on technology. Specifically, respondents with high levels of reliability are more likely than those with low levels of reliability to apply for firms using AI-based initial screening. However, the moderating role of reliability was not significant in the relationship between the AI interview and the applying intention. Employing uncertainty reduction theory, this study indicated that the relationship between AI-based selection tools and intentions to apply is dynamic, suggesting that organizations should carefully manage their AI-based selection techniques throughout the recruitment and selection process.

Objective : Recently many kinds of food therapies have sprung up to prevent or manage disease and to promote health. Seeing Korean history, the Korean medical doctors have been applying food therapy based on the thought that the dietary sources were as important as the medicine. Therefore, in this study, we designed a mobile edutainment game prototype with the goal of providing education about healthy food knowledge for users who belongs to different constitutional types. Materials and Method : We adopted the Sasang Constitutional Medicine as the medical background knowledge for our edutainment game design. Based on the user study, we developed the process of edutainment system which is composed of 'My game', 'My constitution', and 'My food'. Among the whole process, we developed a prototype for the core module - the 'My game' part. This prototype used a jumping game for mobile devices that is composed of training, level 1 and level 2 stages. Results : From the target user evaluation, it was proved that 1) in terms of the learning effect of healthy diet, the edutainment game we developed has a significant advantage over the conventional learning media. 2) after playing the edutainment game, the good and bad food identification accuracy based on picture and text format were increased by 44% and 42% respectively, and 3) target users perceived enjoyment while using this prototype, as well as showed positive intention to use this game as edutainment tool in the future. Conclusion : We designed and developed mobile edutainment game prototype to educate healthy food knowledge based on Sasang Constitutional Medicine. Through user evaluation, we proved that our prototype enhanced healthy food knowledge and that user accepted the prototype as a beneficial edutainment tool.

Learning accounting has always been a challenge for non-accounting students and managers. Understanding accounting information requires more than a numerical description of financial and income statements. Current accounting practice presents accounting reports in the form of tables with values or in two or three dimensional graphs generated by a spread sheet program. The present study proposes an alternative visualization with metaphor from nature as a learning device for novice users and managers. After surveying various kinds of plants, the lotus flower was chosen as an attractive analogy because every part of the plant from leaves to roots is usable and can have economic value. Moreover, lotus flowers, whether man-made or natural, can easily be part of a familiar, natural ecology representing both beauty and serenity. Results from online survey respondents (n = 220) showed that there was no significant difference on overall usability of the Lotus visualization between expert users and novice users. However, verbally-oriented users differed Significantly from visually-oriented users in their usability assessment, perceived usefulness, and intention to use the Lotus visualization.

The main function of plastic materials in food packaging is to preserve a food for safe transportation and storage. The interactions between food and plastic materials in food packaging have become increasingly important for food quality and safety because monomer, low molecular weight components, or additives of plastic packaging materials can migrate into a food. The use of antioxidants in plastic materials can help protect the degradation of film itself and retard the oxidation of a packaged food containing lipid, through the migration of antioxidant from the packaging to a product via an evaporation / sorption mechanism. Nowadays, antioxidant (BHT) impregnated plastic materials are used for commercial food packaging application with the intention of achieving an extended shelf life of food in USA. Alpha tocopherol, as one of the most important free radical scavengers, has been well known in biological systems. Moreover, the potential use of alpha tocopherol as an additive for polymers used in the packaging industry may offer the most positive perception from both consumers and manufacturers. Alpha tocopherol has been used as an antioxidant for polyolefin resins fabricated to both bottles and film and has applications in the food packaging industry as a replacement for BHT. Today, alpha tocopherol offers an attractive choice for use as an antioxidant in polymers. This paper provides an overview of antioxidant effectiveness and applications for its use by the food packaging industry based on the evaporation-sorption mechanism of a packaging model product, where quality is associated with lipid oxidation. Important analytical techniques for predicting antioxidant interaction between the package system and product are discussed.

Virtual communities have been suggested to play important roles such as attracting customers, building customer loyalty, and leading to commercial transactions. Little research in marketing has focused on virtual communities in spite of its importance indicated by many practitioners and conceptual studies. More specifically, little research has empirically examined factors of customer participation and its consequences. This research investigate if customers' participation motives in virtual communities affect their sense of community and if sense of community affects customers' loyalty towards and purchase intentions from the website offering the community service. One hundred ninety six questionnaires were collected from individuals who have participated in and have been involved in online activities in various virtual communities. Major results of this research can be summarized as follows. First, participation motives employed significantly affected customers' sense of community and more specifically, perceived ease of use and perceived playfulness had a large influence on the customers' sense of community. Second, customers' sense of community positively affected their loyalty toward the community and more specifically, membership and emotional connection had a large influence on loyalty. Third, customers' sense of community did not affect directly their purchase intentions. Fourth, customers' loyalty toward virtual communities had a significant, positive, although marginal, influence on their purchase intentions.

Online communities are getting more popular with the development of information technology. It is essential that community members participate actively and share their contents or opinions continuously for the success and growth of online communities. However, it is revealed that most of members just take the role of passive observer. They are lurking community information and contents without any contribution. In this sense, this study focuses on explore lurking behavior of online community members. This study investigates the effect of the characteristics of online community, community members, and personal traits on user's lurking intention. Member familiarity and community identity have a strong positive effect on de-lurking intention, while the perception of usefulness and ease of use for communities and member expertise have a negative effect on de-lurking intention. Interestingly, users with a low level of self-esteem have higher level of motivation of participation than those with a high level of self-esteem. Finally, this study proposes several strategies to enhance information and contents sharing in online communities.

The purpose of this study was to examine the development trend of smart fiber by textile companies in Daegu/North Gyeongsang Province. This examination includes the development fields of smart fiber, investment size, information sources and the use degree of those, research-related infrastructure, relationship between companies' characteristics and their interests in smart fiber. Research data were collected by a survey. The definition and classification(4 areas and 12 development products) of smart fiber followed ones of Smart Fiber Technology Roadmap by the Ministry of Commerce, Industry and Energy. Data were analyzed using SPSS 11.0 program for frequency, means, t-test, and $X^2$-test. Among respondents, the numbers of dying and finish companies and export traders were the highest. It revealed that 19.6% of companies were developing smart fibers. Within 12 development products, vapor permeable/waterproof fiber showed to be most being developed, while medical fiber for human has not been developed and wasn't made an investment plan for developing. It was discovered that the biggest problem of smart fiber development was the lack of experts and the best outcome of smart fiber development was preoccupation of future market. It showed that companies got information from textile fairs but didn't often use information sources. The companies appeared to have a weak intention about research of smart fiber. The more important a company considered functionality of textile products and the more innovative and stabler the company was, the higher interest in smart fiber companies had. It was concluded that textile companies in Daegu/North Gyeongsang Province were aware of the importance of smart fiber development but they were not strongly interested in it and not enthusiastic in taking action on it.

With the development of ICT, the use of software has become essential for organizations to exchange information or manage operations. However, security and software management issues that have increased with the development of ICT are issues that need to be continuously addressed. In 2021, the U.S. government has standardized and established SBOM as one of the countermeasures for software security. This research was initiated as a study to lay the groundwork for the introduction of SBOM in Korea. Based on the effects of SBOM characteristics on adoption intention, we tested management support and institutional support as moderating variables. As a result, security management was found to be a significant moderating variable for management support, and transparency was found to be a significant moderating variable for government institutional support. This study verified that SBOM adoption requires both corporate and government efforts, and the variables that are important from each perspective are different. We hope that this study will contribute to the development and adoption of SBOM.
