Type 1 diabetes is on the rise worldwide. Although nutrition education for patients with diabetes has become a routine practice, specifics and impacts of such educations need to be more researched. This study examined the status of nutrition knowledge, dietary attitude, and dietary behavior among children and adolescents with type 1 diabetes (9-19 year-old) and explored factors influencing dietary behaviors related to diabetes by applying the Theory of Planned Behavior. Face-to-face interviews, using a pre-tested structured questionnaire, were conducted with 32 participants (11 boys and 21 girls) with type 1 diabetes followed by a diabetes clinic in a university hospital. This study found that the level of nutrition knowledge related to diabetes was generally low at 4 points out of a possible 10, however, the dietary attitude related to diabetes was found to be generally good at 26 points out of a possible 30. Participants were motivated to follow medical staff recommendations the most; however, their family was also important. Perceived behavioral control was low especially for eating-out and portion control. The dietary behavior related to blood glucose control showed low at 13 points out of a possible 20. Regression analysis showed that perceived behavioral control (p < 0.001) was significantly related to the dietary behavior related to blood glucose control. This rare study with children and adolescents with type 1 diabetes showed that nutrition education should include a component to improve perceived behavioral control through high-risk situation management.

The study examines an empirical case that explores the key constructs of the Unified Theory of Acceptance and Use of Technology (UTAUT) (Venkatesh, Morris, Davis & Davis, 2003) and the relationship between security and privacy of the Theory of Perceived Risk (TPR) (Bauer, 1960). This study employs survey data of 200 young Internet users aged 18 to 25. The study was conducted through two steps: preliminary research by qualitative research method to form the official research scale then formal research by quantitative research method using CFA and SEM to test the research model. The research results show that performance expectancy and social influence significantly predict behavioral intention to use e-wallets in payment. In contrast, the factors, namely, security and privacy, and effort expectancy, are statistically insignificant on behavioral intention. Nevertheless, the facilitating conditions factor still affects the behavior of using e-wallets. The study proposes a model to generalize the online payment environment through the integration of UTAUT and TPR models that are important for online payment management and researchers in the technology environment. The findings of this study suggest that social influence significantly affects the intention of young people to use e-wallets instead of security and privacy.

Purpose - Digital trade, which started in the early 2000s, is showing a sharp increase due to the recent pandemic. However, despite this proliferation, users' acceptance of innovation is very slow. Cloud services are at the center of digital trade activation. This study aims to contribute to the spread of digital trade through empirical analysis of the resistance factors that hinder the use of cloud service-based digital trade using the innovation resistance theory and the status quo bias theory. Design/Methodology/Approach - In order to achieve the research purpose, this study was conducted with 171 entrepreneurs using cloud service-based digital trade. Structural equation model(SEM) was used through empirical analysis. Findings - As a result of the study, it was found that the complexity of technology, perceived risk, compatibility, and trust in service providers had a significant effect on innovation resistance, and policy trust did not affect innovation resistance. Also, security concerns and institutional trust were analyzed to have a significant effect on the trust of service providers. Research Implications - This study is meaningful to help the rapid diffusion of innovative technologies through empirical analysis of factors that lower the intention to accept cloud service-based digital trade.

Purpose Global fintech industry is proliferating. Although domestic investment in fintech service is also increasing fast, user acceptance of fintech payment service seems slower than expected. Previous fintech literature mainly focuses on overall characteristics and technical aspects of fintech including security issues and explores factors affecting the service adoption. This study aims to examine crucial factors affecting user's resistance intention to fintech payment service adoption. The research model was formulated based on innovation diffusion theory and status quo bias theory and validated empirically. Design/methodology/approach The proposed research model was empirically validated with 149 responses from college students who have used fintech payment service. The component-based SEM was employed for data analysis. Findings The significant findings are as follow. First, compatibility has significant negative effect and complexity, and perceived risk has a positive effect on user resistance. Second, institutional trust does not show a significant effect on user resistance but has an indirect effect through the mediation of trust in service provider. Finally, trust in service provider shows the significant negative effect on user resistance.

인터넷을 통해 중고차가 유통되기 위해서는 구매자가 눈에 보이지 않는 판매자와 중개인에 대해 편안함을 느끼면서 거래를 할 수 있어야 한다. 이에 신뢰는 인터넷을 통한 거래(유통)에 있어서 주요한 요인으로 인식되고 있다. 인터넷에서 중고차 거래는 구매자와 판매자는 서로 볼 수 없고 모르기 때문에 신뢰는 더욱 중요하다. 특히, 중고차 사이트의 신뢰는 매우 중요하다. 본 연구는 중고차 거래에서 구매자의 신뢰형성에 중요한 역할을 하는 요인이 무엇인가를 파악하는 것이다. 특히 품질위험을 높게 지각하고 있는 구매자가 단지지각된 이점만으로 구매의도가 늘어나지 않고 중고차 사이트의 신뢰형성이 되어야 구매의도가 늘어난다는 것을 보이고자 한다. 이를 위해 인터넷 중고차 사이트 이용 경험자중 품질위험을 높게 지각하고 있는 사람을 대상으로 실증분석을 실시하였다. 연구모델은 독립변수(지각된 이점, 구매자의 신뢰성향, 구전효과, 구매자의 지각된 크기, 검사 및 보증정책), 매개변수(중고차 사이트 신뢰도), 그리고 종속변수(구매의도)로 구성되어 있다. 분석결과, 지각된 이점만으로 구매의도가 증가되는 것이 아니라 중고차 사이트 신뢰가 형성되어야 구매의도가 높아진다는 즉, 중고차 사이트 신뢰가 중요한 역할을 하고 있는 것을 입증하였다. 중고차 사이트의 신뢰에 중요한 영향을 미치는 요인은 검사 및 보증 정책으로 일반적인 인터넷 쇼핑몰과는 다른 중고차 거래 특유의 신뢰 특성을 보여주고 있다. 지각된 이점은 중고차 사이트의 신뢰를 통해서만 구매의도에 영향을 미치는 완전매개효과가 있었다. 따라서 인터넷을 통한 중고차 거래의 활성화를 위해서는 인터넷 중고차 사이트의 신뢰를 향상 시키는 것이 선결 과제임을 본 연구결과는 시사하고 있다.

Health Belief Model is a socio-psychological theory of decision making to individual health-related behaviors. This study was aimed to develop an effective education program for hypertension based on health belief model. The main factors of health belief model were investigated by focus group interview (FGI) with 23 hypertensive or prehypertensive subjects aged over fifty years. 'Perceived susceptibility' to hypertension was family history, neglect of health care, preference for salty food, broth of soup and stew. Lifelong medication, complications, and medical costs were reported as 'perceived severity' of hypertension. 'Perceived benefits' of hypertension management were decrease of medicinal dose, reduction of medical costs, and healthy eating habits of the family, while 'perceived barriers' were lack of palatability of low salt diet, convenience-oriented dietary habits, and limited choice of foods when eating out. Subjects mentioned TV health programs, public health center programs, and advice from doctors and family as 'cues to action' of hypertension management. These qualitative information provided basis for developing a nutrition education program for hypertension which could be implemented in the public health center. Eight week program was composed of understanding hypertension, risk factor management (eating habits, weight), low salt diet (principles, cooking), advanced management for healthy diet in 2 sessions, and summary. Each session was designed to alert the susceptibility and severity, to emphasize the benefits, and to reduce the barriers by providing dietary monitoring, practical advice, and action tips.

This study aims at understanding gender difference in trust and the related factors affecting the intention to purchase voice speakers VS. VS are one of the innovations that are emerging at a fast pace in the market. Although it seems to be widely embraced by both genders, people do not intend to use them in some cases due to a lack of trust and the rumors circling these types of technologies. Nevertheless, there are particular barriers to the acceptance of VS technology between females and males due to unfamiliarity with the effective components of such technologies. Therefore, assuming that increasing the knowledge-based familiarity with an effective technique is essential for accepting it. So far, only little is known about VS and its concepts to increase the familiarity and, as a consequence, the acceptance of effective technology. Technology adoption in gender has been studied for many years, and there are many general models in the literature describing it. However, having more customized models for emerging technologies upon their features seems necessary. This study is based on Theory of Reasoned Action and trust-based acceptance which provides a background for understanding the relationships between beliefs, attitude, intentions, and subject norms and how it's affecting gender trust in VS. The statistical analysis results indicate that perceived system quality and perceived interaction quality have stronger influences on trust for males, while privacy concern and emotional trust have stronger influences on trust for females with the intention of purchase for both genders. Our study can be beneficial for future research in the areas of Perceived risk and Perceived utility and behavioral intention to use and human-technology interaction and psychology.
