Nowadays, with the development of the internet and e-commerce, opening tea shops online has become an increasing choice for selling tea. However, the product page information of many online tea shops cannot effectively attract consumers, resulting in their profits being compromised. To investigate this, we conducted this paper and hope to provide effective suggestions. This paper is based on 229 questionnaires and selects the product page information of online tea shops as the research object. Using the four dimensions of perceived value theory as independent variables with consumer purchase intention as the dependent variable. A structural equation model was constructed to analyze the role of the perceived value of product page information in online tea shops how influencing consumers' purchase intentions. It was found that information on the perceived functional value of online tea shops did not have a significant positive effect on consumer purchase intentions. However, information on the perceived monetary value, perceived social value, and perceived emotional value of online tea shops had a significant positive impact on consumers' purchase intentions. Based on the above conclusions, online tea shops should focus on the expression of product page information to enhance the level of consumers' perceived value of tea products, thereby enhancing their intention to purchase tea products.

The most important factor in pre-school children's psychological perception is ease of learning, and the closest measure is "natural" interaction. This study aims to explore the potential of tangible user interfaces (TUI) for AR collaboration for children's cognitive development. The conceptual model is constructed by analyzing physical interaction, spatial perception and social collaboration on the usability of TUI, to explore the role of TUI in pre-school children's cognition. In the empirical study, children aged 3-6 were taken as research objects. The experimental tool is "Plugo" education application. Parents answered questionnaires after observing their children's use. Research shows that physical interaction are the most critical factor in TUI. TUI is beneficial to the cultivation of spatial ability. The results are as follows: 1. Cronbach's Alpha and KMO were 0.921 and 0.965, which were significant and passed the reliability and validity test. 2. Through confirmatory factor analysis (model fit index, combinatorial validity), we found that physical interaction were closely related to usability. 3. The path analysis of the relationship proves that usability has a significant impact on the cultivation of pre-school children's spatial ability.

Approximately 40,000 elevators are installed every year in Korea, and they are used as a convenient means of transportation in daily life. However, the continuous increase in elevators has a social problem of increased safety accidents behind the functional aspect of convenience. There is an emerging need to induce preemptive and active elevator safety management by elevator management entities by strengthening the management of poorly managed elevators. Therefore, this study examines domestic research cases related to the evaluation items of the elevator safety quality rating system conducted in previous studies, and develops a statistical model that can examine the effect of elevator maintenance quality as a result of the safety management of the elevator management entity. We review two types: odds ratio analysis and logistic regression analysis models.

This study aims to propose the implementation of innovative payment models in Korea in order to promote the financial sustainability of the national health insurance system by reviewing the current status of the payment system in Korea and examining other countries' experiences with various innovative payment models. Korea primarily uses a fee-for-service payment system and additionally uses various payment systems such as case payment, per diem, and pay-for-performance. However, each payment system has its limitations. Many OECD (Organization for Economic Cooperation and Development) countries have pointed out the limitations of existing payment systems and have been attempting various innovative payment models (e.g., add-on payment, bundled payment, and population-based payment). Therefore, it is essential for Korea to consider innovative payment models, such as a mixed payment model that takes into account the strengths and weaknesses of each payment system, and to design and pilot these models. This process requires stakeholders to work together to build a social consensus on the implementation of innovative payment systems and to refine legal and systematic aspects, develop an integrated health information system, and establish dedicated organizations and committees. These efforts towards innovative payment models will contribute to developing a sustainable health insurance system that ensures the public's health and well-being in Korea.

The demand for metaverse is increasing rapidly due to the development of 3D information technology and the pandemic situation caused by COVID-19. Small and medium-sized enterprises(SMEs) are also in increasing demand for metaverse in the community, meetings, and customer services of their employees. Based on the UTAUT model, this study investigated the acceptance of the Metaverse-type information system(IS) by employees of SMEs. Using the responses from 170 SMEs employees, we conducted the regression analyses SMEs employees' usage intention on Metaverse-type IS. The results of the research analyses were as follows. First, among the variables of the UTAUT model, performance expectations, social influence, and promotion conditions had a significant effect on the intention to use. Second, among the variables derived from the industrial specificity of Metaverse-type IS, only individual innovation had a significant influence on the intention to use. Last but not least, in the relationship between the intention to use Metaverse-type IS and the influencing factors, only individual innovation was significant in the moderating effect according to past metaverse use experience.

This dissertation studied the psychological cost, which converted the mental pain suffered by the victim of a traffic accident and his/her family, friends and people around him/her into social costs. Three methodologies - Choice Experiments, Direct Question and Dichotomous Choice Question - were used to design questionnaires, and models were built for each questionnaire design method. When building models, a logit model was used, which is used most frequently in probabilistic choice model. And the tobitmodel was used to make direct questionnaires. When verifying these models, although there were some differences in each model, suitability of most models and credibility of each coefficient were meaningful around the credibility level of 95%. According to the analysis, domestic psychological cost produced through the assessment model of psychological cost was 15.63 million won per person or 5.1 trillion in total, assuming 37.1% of total traffic accident cost.

Improved nutritional intake contributes to maintaining health and quality of life in elderly population and also reducing individual and social medical costs. Most of nutrition assistance programs for elderly, such as congregate or home-delivered meal programs, are not currently serviced in rural communities mainly due to low cost efficiency of program operation. However, the needs and necessity of such programs are presumed to be higher in rural area where the population density of elderly at nutritional risk is relatively high. Therefore, the purpose of this study was to develop a community-based meal program for the rural elderly. In 2007, four rural communities located in Jeon-Nam province were selected and the pilot meal program was applied for three months. Following are key features of the meal program model developed in this study: 1) meal production and service are operated by elderly participants to overcome the voluntary personnel shortage 2) utilization of locally-produced foods is maximized to reduce the meal cost, 3) traditional cooking methods are applied to adjust the food preference of elderly, and 4) foods are serviced on site to minimize the food safety problem possibly caused by delivery process. The pilot programs resulted in high satisfaction with the programs of participating elderly. The community-based meal program model developed in this study is expected to be used as an effective nutrition and health intervention model for the rural elderly.
