Objective: The main purpose of this study was to examine the direct and indirect effects of parent-adolescent communication (through adolescent optimism) on adolescent conflict-coping styles. Methods: A total of 337 high school students participated in this study. They completed questionnaires about communications with their parents and their own optimism and conflict-coping styles. Data were analyzed using t-tests, correlations, and SEM. Results: Neither father- nor mother-adolescent communication had direct effects on adolescent conflict-coping styles. However, mother-adolescent communication had an indirect effect on conflict-coping styles, mediated by adolescent optimism. Adolescents who had open communication with mothers displayed higher levels of optimism, which led to more positive conflict-coping styles. In addition, multigroup analyses revealed that there were significant gender differences in direct and indirect effects. For boys, mother-adolescent communication directly influenced adolescent conflict-coping styles; however, father-adolescent communication did not directly or indirectly affect adolescent conflict-coping styles. For girls, neither father- nor mother-adolescent communication had direct effects on conflict-coping styles; only optimism had a significant effect on conflict-coping styles. Conclusion: The findings from this study suggest that communication with mothers and fathers have different effects on adolescents' conflict-coping styles. These findings have implications for future research and practice by emphasizing the importance of parent-adolescent communication and optimism in designing conflict-coping programs for adolescents.

As the demands for the safety and convenience applications of the vehicles increase, the data load for the In-vehicle Network has increased significantly. As a result, a deterministic and fault-tolerant communication system is required to implement the safety critical applications such as X-by-wire systems. FlexRay communication system is a new standard of network communication system which provides the high speed serial communication, time triggered bus and fault tolerant communication between electronic devices. In addition to time-triggered communication, as providing of the event-triggered communication such as CAN, FlexRay protocol is able to manage the restricted communication resource more effectively. This paper presents the development of FlexRay driver which will be applied to the future ECU's communication system. To develop the FlexRay driver, the FlexRay requirement specification and FlexRay specification is analyzed. The developed FlexRay driver is implemented by using MPC5567 microprocessor of the Freescale semiconductor. To verify the developed FlexRay driver, the waveform of the FlexRay driver was measured and compared with the CAN communication system. As a result, the bus load is reduced about 13% compared with the CAN communication system.

This study aims to understand the consumers' negative responses to communication failure of chatbots caused by their imperfections. Specifically, this study examines 1) the relationship among chatbot's communication failure, dissatisfaction, negative behavior (complaint, negative word-of-mouth (nWOM), and inertia); 2) the moderating effect of technostress on the relationship between chatbot's communication failure and dissatisfaction; 3) the differences in the negative responses between the generation MZ and the previous generations. Data were collected via an online survey. First, the participants interacted with the chatbot developed for this survey, to experience the chatbot's communication failure. Thereafter, they responded to a questionnaire. PLS-SEM was conducted using the R software environment to test the hypotheses. This study empirically identified that chatbot's communication failure positively affected dissatisfaction. In addition, the customers who were more dissatisfied with the chatbot's communication failures were more likely to complain than engage in nWOM. Compared to the generation MZ, chatbot's communication failure caused a higher level of dissatisfaction in previous generations. The results suggest that online shopping malls should carefully introduce an improved chatbot service after minimizing its communication failure rate. The chatbot developers of online shopping malls targeting middle-aged and elderly consumers should strive to develop and implement strategies to further alleviate consumers' dissatisfaction in the situation of chatbot's communication failure.

Uncrewed aerial vehicles (UAVs) have become a vital element in nonterrestrial networks, especially with respect to 5G communication systems and beyond. The use of UAVs in support of 4G/5G base station (uncrewed aerial vehicle base station [UAV-BS]) has proven to be a practical solution for extending cellular network services to areas where conventional infrastructures are unavailable. In this study, we introduce a UAV-BS system that utilizes a high-capacity wireless backhaul operating in millimeter-wave frequency bands. This system can achieve a maximum throughput of 1.3 Gbps while delivering data at a rate of 300 Mbps, even at distances of 10 km. We also present the details of our testbed implementation alongside the performance results obtained from field tests.
