This paper deals with the process and requirements of a capstone design project performed by undergraduate students. We discuss about the preliminary study for the capstone design, the derivation of a subject, the level descriptor of the subject, and the system requirements. And then, we summarize the results of the capstone design project entitled as Microsoft Azure based IoT (Internet of Things) system which is performed by 4 undergraduate students during 10 months. This system is composed of a Zigbee sensor network, the TCP/IP Internet, an IoT server, and a smartphone application program, with which we can gather the sensor data and control actuators at the far away area.

본 논문에서는 최근 유아대상으로 무분별한 스마트폰 기기 노출 등으로 인한 피해의 심각성을 알고 유아교육에서 인터넷 윤리 및 스마트폰 기기의 올바른 사용이 제대로 이루어 질수 있도록 교육 방법을 제안하는 것이다. 제 4차 산업혁명으로 인하여 연령과 상관없이 과도하게 스마트기기에 많이 노출되고 있다. 따라서, 유아기때부터 올바른 정보 윤리 의식 및 적절한 컴퓨터 사용을 할 수 있는 교육이 이루어지며, 유아 스마트폰 증후군을 예방하여 건전하고 안전한 사이버 세상이 이루어지도록 해야 한다. 그러나 아직까지 유아교육분야에서 정보 윤리 및 스마트폰 중독에 대한 프로그램이 특강형태로 이루어지고 교재교구들이 부족하며, 다양한 활동이 개발되어지지 않고 있는 실정이다. 따라서, 본 연구는 정부차원에서 각 센터와 기관들과 잘 협업이 이루어지도록 유도하며, 전문가들에 의해 다양한 활동이 개발되고 교재교구가 제작될 수 있는 방안을 제안하고자 한다.

유아기는 언어를 습득하는데 있어 가장 중요한 시기이다. 이런 중요한 시기에 언어를 습득하는데 흥미를 느끼지 못하고 학습에 쉽게 지루함을 느껴 올바르게 언어 습득을 하지 못하는 유아들이 많다. 이에 대하여 시각 정보와 청각 정보의 결합을 통한 멀티미디어 매체를 이용해 언어 습득에 대하여 올바른 유아 시기를 보내게끔 본 논문에서 제안하고 있다. 또한 햅틱 기술을 이용하여 학습자가 쓰기 학습에 흥미를 느낄 수 있게 하였으며, 피드백 과정을 통하여 올바른 언어 습득에 기여한다.

Purpose: This study was conducted to confirm the usability of virtual reality-based anatomy education programs for nursing college students and to identify factors that affect their usability. Methods: Data were collected from 143 nursing college students in Gyeonggi-do using a structured questionnaire from May to June 2022. The data analysis was analyzed using real numbers, percentages, means and standard deviation, ANOVA, Scheff's test, Pearson's correlation, and multiple regression using the SPSS/WIN 23.0 program. Results: The subject's usability was 4.26 points (out of 5). The variable that has the greatest influence on the usability of virtual reality-based anatomy education programs is perceived innovation (β=.370, p<.001), followed by perceived pleasure (β=.295, p=.001), perceived ease (β=.253, p<.001), smartphone usage time per day (β=.102, p=.031). These variables explained 70.6% of the usability of virtual reality-based anatomy education programs. Conclusion: The results of this study can be utilized as basic data for a virtual reality-based anatomy education program that will be developed and applied to nursing students in the future.

Recently, school violence problem has increased serious. And this is not only an individual issue but also this is a social problem. Realistically, not only physical violence, cyber violence using the smartphone is very serious. And if the elementary school students are exposed to cyber violence, it becomes even more serious problem. Therefore, we proposed an Smart Monitoring app that protect the smart safety such as as a countermeasure against cyber violence to elementary school students. This Conversion Smart app can support grasp service for children using location based service on the smartphone when he will come to the home. And it can support another service that abuse or vulgar language in messenger. Grasps the degree of use of the language that is prohibited friendship in elementary school through this process, it can be derived. And we have future works that is the search rate and response time an inappropriate word on the proposed system.

In college, you can view the online quiz through the cyber education, and online learning. However, if there is no computer has a problem that can not be many students it is in place or not the Internet watch online quizzes. In recent years, many college students have a smart phone, from anywhere, using smartphone, you have utilized various Web surfing, news, and Messenger. In addition, office workers and students, have to learn to put to PDF necessary materials through the smartphone. Advantage of smart phones, have a feature that can be easy to carry and use anywhere at any time. Online learning from anywhere via a smart phone, so that you can see the online quizzes, in this paper, the system that not only online quizzes through a smartphone using the Hybrid-App, you can see in real time the results and scores of the person I proposed.

This study was done to identify the effects of self-monitoring method using smartphone video on self-directed learning ability, competency in nursing skills self-confidence and practice satisfaction of nursing students. It was designed a quasi-experimental study with a pre-post test. The participants were 54 students in the experimental group and 51 students in the control group. There was no significant difference in self-directed learning ability (p = .450) between the groups, but there was a significant difference between the pre-post scores of the experimental group. There was no significants difference of competency in nursing skills, self-confidence and practice satisfaction between the two groups. In conclusion, the self-assessment learning method using smartphone video during the self-practice is considered to be an effective method to improve the self-directed learning ability and to ensure the accuracy and skill of the technique.

Increasingly important user based service on the smart media era, and increasing awareness about the user experience. In this study, by considering these realities, what impact location based constructs on smartphone environment, continuous intention to use you want to identification. Thus, this study conducted of preference the influencing factors for location based constructs. First steps, based constructs known empirical studies were categorized information, entertainment, safe&emergency, navigation&tracking and advertising& commerce. Second Steps, the categorized factors were analyzed preference relationship between constructs using AHP(analytic hierarchy process) technique. Questionnaire survey was conducted to those who employees S Telecom in Busan city and Gyeongnam province during 2000. 4. 15 and 2014. 4. 30. The result of the analysis might be summarized that the navigation(0.133) has the highest preference ran in the constructs. Based on these findings, several theoretical and practical implications were suggested and discussed.

Recently, the importance of the internet of things (IoT) education has been emphasized due to the progress of research on IoT technology. Therefore, universities require an efficient IoT course. In this paper, we propose an undergraduate IoT course using the Bluetooth function of smartphone and Arduino kit. The proposed embedded IoT class uses the Bluetooth capabilities of the smartphone to connect Arduino and activate various sensors to encourage students to become interested in the class. According to students' midterm and final exam scores, students programming skills have been improved since students' projects were in progress during the course. Further, according to students' survey, the proposed IoT class is very effective in understanding the embedded IoT and 75% of the students satisfied with the proposed course.
