In this paper, we implemented a mobile application of location-based augmented reality that combines self-sensing technology and various safety information using technological advancements of the smartphone. Vessel navigation is a suitable area for augmented reality because it requires accurate knowledge of the distance and location of destinations, danger zones, AtoN, and adjacent vessels. Current smartphone applications only provide 2D images and location information. Such applications do not include information about the surrounding environment, and as a result, they can only function using their own sensing information and surrounding information into a location-based augmented reality. If you provide a variety of sensor information embedded in the smartphone to 'BadaGO', the implemented application through this study, 'BadaGO' can provide safe navigation information to the user device in real time with a variety of its own formed information. The user has a high practicality and applicability of a small ship that is supplied with safe navigation information in a changing marine environment only by providing information through the application on the smartphone.

Purpose : Middle school students in the early stages of adolescents need balanced growth and development, and they are in the process of forming healthy lifestyles and are in an important period when they need to lay the foundation for a healthy life through active health management and guidance. Through systematic health-related policies and education, I intend to lay the groundwork for them to form healthy lifestyles in their high schools and adulthood. Methods : For this study, a survey was conducted from September 1 to October 30, 2019, and 300 middle school students based in Busan Metropolitan City were surveyed. Based on the analysis and results of preceding studies, a research model was set up to find out the effect of family support, health control activities and self-efficacy on health promoting behaviors and how health promoting behaviors affect the quality of life. Results : First, if family support is high, health promotion behavior and quality of life are analyzed to be high, so family support is affecting health promotion behavior and quality of life. Second, health control behavior had a significant effect on health promotion behavior, but did not affect the quality of life. Third, self-efficacy was having a significant effect on health promotion behavior and quality of life. Fourth, health promotion behavior was affecting the quality of life. Conclusion : In order to improve the quality of life, middle school students should first increase their health promotion behavior, and it is important to be supported by their family members and strengthen their self-efficacy as variables that increase their health promotion behavior. First of all, they should be given the infinite trust of the family and the strong belief that the family always supports them, and based on this, the student himself will be able to strengthen his or her self-efficacy. In addition, the process of physical and mental change of students comes to everyone, but during this process, members of society, such as families and schools, should send them support and trust so that they can grow up to be the decent members of society.

One of the most important matters in designing network and realizing service, is to grip on the traffic characteristics. Conventional traffic prediction and analysis used the models which based on the Poisson or Markovian. Recently, experimental research on the LAN, WAN and VBR traffic properties have been pointed rut that they weren't able to display actual real traffic specificities because the models based on the Poisson assumption had been underestimated the long range dependency of network traffic and self-similar peculiarities, it has been lately presented that the new approach method using self-similarity characteristics as similar as the real traffic models. Therefore, in this paper, we generated self-similar data traffic like real traffic as background load. On the existing ABR congestion control algorithm, we analyzed by classify into ACR, buffer utilization. cell drop rate, transmission throughput with the representative EFCI, ERICA, EPRCA and NIST twitch algorithm to show the efficient reaction about the burst traffic.

Chronic diseases management can be effectively achieved through early detection, continuous treatment, observation, and self-management, rather than a radar approach where patients are treated only when they visit a medical facility. However, previous studies have not been able to provide integrated chronic disease management services by considering generalized services such as hypertension and diabetes management, and difficult to expand and link to other services using only specific sensors or services. This paper proposes clinical rule flow model based on medical data analysis to provide personalized care for chronic disease management. Also, we implemented that as Rule-based Smart Healthcare System (RSHS). The proposed system executes chronic diseases management rules, manages events and delivers individualized knowledge information by user's request. The proposed system can be expanded into a variety of applications such as diet and exercise service in the future.

With the spread of COVID-19 and the preference for untact services, kiosks, which is one of self-service technologies, have been expanding into various service fields. Kiosks have some advantages of reducing labor costs and increasing work efficiency, but they often cause difficulties in the process of using kiosks. In this vein, this study examines the key antecedents affecting consumer's continuance intention toward kiosks by integrating technology anxiety and innovativeness into the expanded expectation-confirmation model. The research model was verified for the MZ generation to examine the perceptions of MZ generation about Kiosks. This is because if the MZ generation feels technical anxiety or difficualty about using kiosks, customers of other generations can expect to feel even more uncomfortable. As a result of the analysis of this study, it was confirmed that technical anxiety has a significantly negative effect on consumer's continuance intention toward kiosks. However, among the characteristic factors of customers, innovativeness did not significantly consumer's continuance intention toward kiosks. Based on our findings, it is expected that service companies will be able to understand the mechanism of forming consumer's continuance intention toward kiosks and pursuit several management activities for successfully adopting kiosks.
