In the future, infotainment systems are expected to play a pivotal role in mobility ecosystems connecting users and vehicles. This study draws user-experience factors from reviews of Android Auto, a car infotainment application, and analyzes factors that affect satisfaction. The user-experience factors of infotainment have been redefined based on previous studies. To analyze actual user-experience factors, topics are obtained, applied, and interpreted from user discourse through topic modeling. Sentiment analysis and logistic regression are used to determine positive and negative user-experience factors that affect satisfaction. Results of the empirical analysis show that Ease of Use and Understandability are factors that have the greatest impact on satisfaction, and Flexibility, Safety, and Playfulness are factors that have the most critical effect on dissatisfaction. Therefore, this paper suggests ways to improve the satisfaction level of the infotainment system, and establishes a strategy accordingly.

The purpose of this study is to study the user experience that provides psychological stability when paying for mobile e-commerce pay one-touch. Through literature and case studies, e-commerce pay one-touch payments were identified, and user experiences were investigated through surveys and in-depth interviews. The survey based on Aaron Walter's model of user needs received a high average of functionality and usability for one-touch payments, but reliability and stability were somewhat low. Afterwards, four design improvement plans were presented to supplement psychological stability by analyzing in-depth interviews conducted based on the User's Eye View of User Experience Design model. This study is expected to be helpful in basic research on the payment experience where you can feel stable when taking one-touch payments.

Objective: We aimed to investigate current expectations and clinical adoption of artificial intelligence (AI) software among neuroradiologists in Korea. Materials and Methods: In April 2022, a 30-item online survey was conducted by neuroradiologists from the Korean Society of Neuroradiology (KSNR) to assess current user experiences, perceptions, attitudes, and future expectations regarding AI for neuro-applications. Respondents with experience in AI software were further investigated in terms of the number and type of software used, period of use, clinical usefulness, and future scope. Results were compared between respondents with and without experience with AI software through multivariable logistic regression and mediation analyses. Results: The survey was completed by 73 respondents, accounting for 21.9% (73/334) of the KSNR members; 72.6% (53/73) were familiar with AI and 58.9% (43/73) had used AI software, with approximately 86% (37/43) using 1-3 AI software programs and 51.2% (22/43) having up to one year of experience with AI software. Among AI software types, brain volumetry software was the most common (62.8% [27/43]). Although 52.1% (38/73) assumed that AI is currently useful in practice, 86.3% (63/73) expected it to be useful for clinical practice within 10 years. The main expected benefits were reducing the time spent on repetitive tasks (91.8% [67/73]) and improving reading accuracy and reducing errors (72.6% [53/73]). Those who experienced AI software were more familiar with AI (adjusted odds ratio, 7.1 [95% confidence interval, 1.81-27.81]; P = 0.005). More than half of the respondents with AI software experience (55.8% [24/43]) agreed that AI should be included in training curriculums, while almost all (95.3% [41/43]) believed that radiologists should coordinate to improve its performance. Conclusion: A majority of respondents experienced AI software and showed a proactive attitude toward adopting AI in clinical practice, suggesting that AI should be incorporated into training and active participation in AI development should be encouraged.

The purpose of this study is to develop and secure the human resources of SMEs by examining the causal relationship between job characteart-time job experience and career development of youth. In order to achieve the purpose of the study, 10,119 youths in the middle and high schools in Korea who participated in the panel data collection by the Korea Youth Policy Institute were surveyed from May 20 to July 12 in 2013, Panel data were used. The results of the study are as follows. First, it was found that the part-time job experience had a statistically significant effect on the planning, which is a sub-area of career development. Second, the part-time job experience has a statistically significant effect on attitude, a sub-domain of career development. Third, it was found that the part-time job experience had a statistically significant effect on the self knowledge, which is a sub-domain of career development. Fourth, it was shown that the part-time job experience had a statistically significant effect on career behavior, one of the sub-areas of career development. Fifth, it was found that the part-time experience characteristics had a statistically significant effect on the independence of sub-domains of career development. Therefore, since the part-time work of youth has a positive effect on career development, it is expected that the human resources of the future of SMEs will be secured if they create a place for career experience and job experience in connection with middle, high school and SMEs.

In recent years, coding education has been globally emphasized and the Free Semester System will be executed to the public schools in Korea from 2016. With the introduction of the Free Semester System and the rising demand of Computational Thinking (CT) capacity, this research aims to design 'learning environment' in which learners can design and construct mathematical objects through computers and print them out through 3D printers. Furthermore, it will design learning mathematics by constructing the figurate number patterns from 'soma cubes' in the playing context and connecting those to algebraic and combinatorial patterns, which will allow students to experience mathematical connectivity. It is expected that the activities of designing figurate number patterns suggested in this research will not only strengthen CT capacity in relation to mathematical thinking but also serve as a meaningful program for the Free Semester System in terms of career experience as 3D printers can be widely used.

With the rapid growth of the internet, Social Network Services (SNSs) have played an important role. As the use of SNSs increases, users experience a sense of responsibility to respond to other people's messages or requests, and consequently experience an social overload, feeling too much social support for other users. In this study, we examined the effects of social overload on loneliness and SNS discontinuous usage intention. To verify the research model, data were collected from 83 SNS users and analyzed using SmartPLS, a structural equation modeling tool. The results of this study showed that the communal orientation and the degree of use of SNS influenced the social overload, and the social overload had a significant effect on loneliness and SNS discontinuous usage intention. The findings of this study are expected to help understand the social overload and loneliness in the use of SNS, and may also provide a strategic direction for SNS service providers.

Under social changes focusing diversification, human-oriented ecological values and emotional and pscyhological satisfaction have been considered more important in space. Such trend has developed into interest in the effect of architectural space and shape on human perception and consciousness, and space has been considered as interactive in ecological, psychological and behavioral, and aesthetic terms rather than physical environment. In particular, exhibition space where interactive sympathy between environment and users through emotional experiences is more important, can have appropriate interaction through intended relationships between environment and humans in space. Therefore, this study aims to understand affordance, an internal mechanism of space recognition and human behaviors. Then it analysed representative types of exhibition space for emotional experiences as a characteristic of affordance Based on the results analysed, it is expected that introduction of affordance as real information in space will be helpful for effective connection of space with human emotional experiences.

Globally the interest of large-scale structure has been increasing for the use in various social and cultural events. However various problems for building large-scale structure in South Korea are expected in terms of construction method and site management due to the lack of experience. Construction method and planning significantly affects on making decisions. There are only theoretical approach for constructing large-scale building in domestic with the limited experience of constructing constrained size structure. Through Analytic Hierarchy Process with experts, derived decision factors mostly used construction method in construction of large-scale structure. Derived factors from this study will support making decisions for field management in constructing large-scale structure.
