The information system control includes organizational structure, control mechanism, and management tools which contribute to accomplish the goals of information system: asset safeguarding, data integrity, effectiveness, and efficiency. Information system audit is the process to evaluate whether the information system accomplishs the goals. Information system auditor examine the reliability of information system control and suggest recommendations to improve the information system control. Both information system control and information system audit activities contribute to prevent and detect the computer crime for the organization. This paper proposes a causal model of information system control/audit and the perceived risk of computer crime, and tests the model using a survey on 38 financial institutions in Korea. Statistical results show that information system control and audit significantly reduce the computer crime risk perceived by the user group. The general control has a stronger impact than the application control. In addition, it turns out that the greater the deviation between the importance and the actual level of information system control is, the higher the perceived risk of computer crime is.

With the development of AI, multimedia tools in education offer personalized learning environments, which foster individual competencies. This study aims to examine the effectiveness of smart education as perceived by learners through a case study of university writing classes utilizing multimedia learning tools, and to explore potential applications. To achieve this, a writing course incorporating various multimedia tools to promote interaction was designed and implemented over the course of one semester, targeting 42 university students. Through the semester, student reactions and survey results were analyzed to investigate the effects and satisfaction levels regarding the use of multimedia learning tools in writing instruction as perceived by students. The analysis revealed that multimedia-assisted writing classes effectively fostered learners' autonomy by focusing on individual needs, while also promoting interaction and encouraging spontaneous participation. Students reported recognizing the presence of diverse perspectives by comparing and communicating about each other's writing, leading to an expansion of their own thinking. In using ChatGPT, it was found that students attempted to refine their questions until they obtained the desired answers. They reported that this process deepened their understanding of the essence of the questions. These benefits led to results of high levels of students' active class engagement and satisfaction. This study contributes foundational and empirical data regarding the effectiveness and potential applications of learner-centered smart education as part of fourth industrial revolution integration research.

Objective: This study investigates the influences of vibrations on hedonic satisfaction based on four kinds of perceptions (perceived ease of use, perceived usefulness, perceived enjoyment, cognitive concentration) when mobile gaming. Background: As mobile gaming is becoming more and more popular for smartphone users, they might want to have more hedonic satisfaction instead of focusing on traditional usability criteria such as efficiency, effectiveness, and satisfaction. Method: We conducted a human-factors experiment with 35 male subjects to evaluate hedonic satisfaction in the mobile game configured by 7 vibration types having different levels of intensity and length. Results: The results revealed that the use of vibration significantly increases the perceived ease of use, perceived usefulness, and cognitive concentration. In addition, the intensity of vibration makes differences of perceived usefulness and cognitive concentration. Conclusion: Vibration can be effectively used to improve hedonic satisfaction of smartphone users in mobile gaming when they are not allowed to turn the sound effects on. Application: This study helps game designers effectively provide vibration feedback of mobile games for smartphone users.

Purpose: Waiting occured frequently in the service industry. Because waiting time is perceived as a loss by customers, perceived waiting time affects positive and negative responses to restaurants. If the waiting time is perceived as long, the waiting receptivity to accept the wait may also decrease. Therefore, restaurant stores need to increase waiting satisfaction so that customers can feel the waiting time shorter. Therefore, in this study, the effect of perceived waiting time and waiting satisfaction of customers visiting Taiwanese restaurant companies on waiting acceptability, emotions (positive and negative emotions) and satisfaction is investigated. Research design, data, and methodology: This study examines the structural relationship between perceived latency, waiting satisfaction, emotion, and satisfaction. To verify the purpose of this study, a research model and hypothesis were developed. The questionnaire items were modified and used according to the content of this study based on previous studies. All configurations were measured with multiple items tested and developed in previous studies. Data collected from 407 Taiwanese restaurant customers were analyzed using SPSS 22.0 and SmartPLS 3.0 programs. Confirmatory factor analysis was performed to measure the reliability and effectiveness of the measurement tool. Structural model analysis was performed to validate the study model. Results: The study results are as follows. Perceived waiting time was found to have a positive effect on negative emotions. In addition, it was found that waiting acceptability had a negative effect on negative emotions, and had a positive effect on positive emotions and customer satisfaction. Positive emotions were found to have a significant positive effect on customer satisfaction. Also, waiting satisfaction was found to have a positive effect as a moderating variable on the relationship between perceived waiting time and waiting acceptability. Conclusion: According to the results of this study, perceived waiting time was found to have a negative effect on eating out consumers. However, if the waiting time is satisfied, waiting time will increase the waiting time acceptability. Therefore, if customers are satisfied with the waiting environment by improving the quality of the waiting environment, it will be possible to establish a marketing ^*strategy^* that stimulates the positive effect of the perceived waiting time.

This study aims to investigate the relationship among the learning flow, perceived effectiveness of online learning and learning burnout in college online classes. A total of 149 college students participated in the study and completed the survey including learning flow, learning burnout and demographic information. The results showed that participants with higher learning flow showed less learning burnout. In addition, the perceived effectiveness of online learning partially mediated the relationship between cognitive learning flow and learning burnout, but did not mediate the relationship between defined learning flow and learning burnout. Since learners with higher cognitive learning flow perceived online learning as more effective, it is necessary to find out how to build learners' cognitive learning flow to decrease learning burnout. The results imply that universities should provide students with administrative support and an appropriate online learning environment.
