The purpose of this study is to compare the speed, confidence, and ease of endotracheal intubation in a transfer posture by using the SALT(Supraglottic Airway Laryngopharyngeal Tube), and a direct laryngoscope to improve the ability to implement professional airway management. The subject of the study was an experimental study by a randomized crossover design, targeting 28 first-class emergency medical technicians working in J-do fire station, and the SPSS 20.0 version was used for data analysis. The endotracheal intubation by using SALT showed a significant difference in speed compared to endotracheal intubation by using a direct laryngoscope(p<.001), and also showed a significant difference in confidence and ease(p<.001). If it is transfer to endotracheal intubation by direct laryngoscope, or in the case of transfer patients, if SALT is used, safe and rapid intubation will be possible.

With internet development, many peoples use their email to exchange documents, register for web services, and much more. Some individuals/organizations (including educational institutions) use their own domain name for email instead of a domain provided by commercial email services. However, suppose the domain used for custom email expires. In that case, other individuals/organizations can reuse the domain, and the new domain owner can send and receive all emails incoming to the domain. It makes us concerned about Privacy violations. Email that new domain owners can look into also contains sensitive emails like password reset notifications, credit card statements, order history, and more. In this research, we would like to describe the privacy violations caused by the expired domain used for email that did not remove all dependencies of email users and propose a solution.

To assess the risk level of a public restroom implemented in virtual reality, we sought to evaluate the spatial elements present in the restroom. To provide the theoretical foundation for the evaluation subjects and criteria, we introduced prior research that proposed a checklist to entance the safety of public restroom. To set up evaluation criteria, we analyzed and established based on the theories of Paul J. Brantingham and Patricia L. Brantingham, focusing on the interaction between space and criminals. Ronald V. Clarke's "Routine Activity Theory" was also introduced and incorporated into the evaluation approach. We analyzed based on the correlation between the criminal, user, and spatial elements of the public restroom in terms of the criminal's actions, the spatial relevance to crime, and user exposure during use. Using these criteria, we developed an algorithm to evaluate th spatial elements of public restroom. Based on this, we created an application, demonstrating the feasibility of developing on evaluation tool.

In recent years, the ROK military is promoting Defense Innovation 4.0 with the goal of fostering strong military based on science and technology equipped with artificial intelligence(AI) to prepare for the upcoming population cliff. In particular, at the present time of increased threats of North Korea, the South Korean military is seeking to deal with a decrease in military service resources through the introduction of a Scientific Guard System using advanced technology. TICN which is a core basic communication system to ensure the integrated combat capability of the ROK military is, however, limited to use as a based network for the emerging Scientific Guard System due to the narrow transmission bandwidth with widely spread poor reception area. To deal with this problem, this paper proposes TVWS-based Scientific Guard Systems with TVWS-based wireless network construction technology that has been available for free in Korea since 2017. The TVWS-based Scientific Guard System proposed in this paper, when compared to the existing wired network-based Scientific Guard Systems, has various advantages in terms of minimizing operational gaps, reducing construction costs, and flexibility in installation and operation.

Recently, since the importance of the information communication ethics education for primary and secondary schools has being highlighted, researches and new instructional materials have been published actively. On the other hand, with the advance of e-learning, the various kinds of educational methods which consider the characteristics and the requirement of students are being developed. The educational method for Information Communication Ethics education is no exception. If the practical method for Information Communication Ethics education which considers students' requirements is developed, then a better educational effect can be acquired. In this paper, we decompose instructional design features into 4 components such as goal, model, contents, and media in order to design a better instruction for Information Communication Ethics education. And then, we analyze the relative importance of the instructional design components by using Conjoint method based on our questionnaire result. Finally, we propose an instructional design method for Information Communication Ethics as well as examine the differences among the instructional design components.

While great efforts are being exerted on the reform of teacher training to provide integrated use of ICT in a teaching-learning process with educational informatization, it is still indicated that a teachers' training school fails to prepare leachers for incorporating information Communication and Technology (ICT) properly into an instructional process. Based on this awareness, this study aims at examining and analyzing the ability level of In utilization training for preservice teachers and thus at providing basic data to perform ICT utilization teaching-learning according to the seventh curriculum in a school. For this purpose, a survey was conducted with preservice teachers (seniors) in a college of education, Kongju National University and the collected data were analyzed using a Statistical Package for the Social Science (SPSS) 12.0 program.

The modern society has become full-fledged entry into the information age since spread of Internet. In the information age, internet was developed from the wired access to the wireless Internet access. When a surge in demand for wireless Internet access, efficiency and performance of 2.4GHz band which leads to saturation of the communication was significantly fall. Accordingly, the communication of the 5GHz band came to be interested. In this paper, we studied the design and fabrication of u-slot microstrip patch antenna to be used in wireless communication systems operating at around 5GHz band. To obtain antenna parameters such as patch size, inter patch space, antenna was simulated by HFSS(High Frequency Structure Simulator). From these parameters, u-slot microstrip antenna is fabricated using FR-4 substrate of dielectric constant 4.4. The characteristics of fabricated antenna were analyzed by network analyzer.

In this paper, We suggest electricity power management system which makes a good efficient and minimize wasteness of electricity power. We made electricity power management system based USN(Ubiquitous Sensor Network) for industries, factories, public offices and so on, with optimized system. Simply, we can measure and control electricity power as we plug it outlets. This system can monitor and control electricity power, organizing network of PLC(Power Line Communication) and TCP/IP with the sensor for electricity power. Through the acquisition data, this proposed system can manage and save the electricity power efficiently and also we can connect this system to server, anytime, anywhere with Android phone.
