With the development of information and communication technology, information literacy and utilization are emerging as basic skills necessary for modern people. Accordingly, information education is becoming a basic literacy education for a nation. Unplugged computing is in the spotlight as a major educational method of information education. The main advantage of unplugged computing is that it is easy to convey basic theories or principles of computer science to students through play activities without the help of special information devices such as computers and tablet PCs. However, studies on student evaluation on unplugged computing have been very insufficient. In this study, students' evaluation standards are developed to maximize the educational effect of unplugged computing. The evaluation standards consist of four areas: participation, interest, satisfaction, and understanding of concepts. The results of this study can be used as a basic study for student evaluation of unplugged computing in the future.

The survey participant of 282 older people(47.7%), 42 family caregivers(7.4%), and 266 staff members(44.9%). Results: Whereas most of the older adults living in their home(87.3%) did not experience difficulty while eating, older adults residing in facilities(26.4%) expressed difficulty with the process of putting food into a spoon. The difference between the two groups was statistically significant(p<.001). Wile the older adults living in home considered assistive eating devices(34.5%) as the most important requirement for self-feeding, older adults in facilities considered receiving help(39.3%) as their biggest requirement(p<.009). Older adults, family caregivers, and nursing home staff were not familiar with assistive eating devices and were not aware of their necessity. Conclusion: The study could help increase awareness about assistive eating devices and the importance of self-feeding in research and nursing educational settings.

Smart devices have a variety of affordances to foster meaningful learning in elementary school. For the design of smart learning environments, more research is needed to understand students' smart device usage and their perception of learning with smart devices. In order to capture smart device usage profiles among elementary school students in South Korea, this study carried out Latent Profile Analysis with three constructs: information search, communication, and study. Participants (n=253), who ranged from the fourth to the sixth grade students, were classified into three profiles of smart device usage: low-activity, communication, and high-activity groups. The smart device usage profiles varied depending on smartphone usage experience, and the profiles were significantly related with smart device addiction, not with smart device usage ability. Perceptions of smart education were also significantly associated with the profiles. The high-activity group showed more positive attitudes toward smart education than the others, but no significant difference was found in regard to negative attitudes. Based on the findings, this study discussed implications for the use of smart devices in elementary school.

This paper presents a new method for improving teaching aids with the design and development of a chemistry education platform - the Mixed Reality (MR) Chemistry Lab. Our system provides a new educational experience in which students can simulate a chemistry experiment in a virtual lab and interact with objects using Oculus Helmet-Mounted Displays (HMD) and hand controller devices. The proposed system aims to familiarize students with experimental procedures and safety knowledge before conducting actual experiments. Moreover, students will be able to observe microscopic atomic structure models in three dimensions. Our research also includes a five-part, quantitative evaluation system user tests perform using a quantitative questionnaire consisting of five items, including hardware equipment, immersion, education, interaction sense of control, and degree of difficulty. The evaluation results confirm that this system will be helpful to the educational experience of conducting chemistry experiments with scientific evaluation methods, and the proposed system is also expected to have a broad range of applications in many other subjects.

Objectives: This study was aimed at investigating the oral hygiene device use by cardiovascular disease patients and assessing related factors. Methods: We used data of 1,630 cardiovascular disease patients (including hypertension, stroke, and myocardial infarction) from the 7th Korean National Health and Nutrition Examination Survey (2016-2018). The χ² test and logistic regression analysis were performed to analyze the oral hygiene device use by the subjects and assess related factors. All statistical analyses were performed with the IBM SPSS Statistics, version 20.0. Results: The oral hygiene device use and related factors were significantly higher in patients with an educational level of middle school or below high school, with a score of 1.85 (95% confidence interval [CI] = 1.35-2.53), or college, with a score of 1.93 (95% CI = 1.19-3.14), compared to those with an educational level below primary school. Further, the oral hygiene device use and related factors were significantly higher in patients who answered 'yes', with a score of 1.96 (95% CI = 1.42-2.73), compared to those who answered 'no' to the question on oral examination. Conclusions: More patients with cardiovascular disease did not use oral hygiene devices than those who did. It is necessary to expand the approach of preventive treatment to increase the utilization rate of oral hygiene devices.

This thesis attempts to investigate and analyze the structure of educational simulation devices implemented thus far. conducting a close analysis of their strengths and weaknesses. On this basis the author Presents and implements a new method of simulation, and continuously upgrades it for increased stability and convenience. The most important aspects of the educational simulation device described in this thesis are: first removing the editing function (scenarios. single line diagrams, and point DB), which the instructor finds time-consuming and inconvenient to use; second, developing and installing the program so as to calculate electric power flow that can measure fluctuations measurements after changing the system status; and third. implementing a Client/server mode to build a system that will make it possible to train many people at a time in remote locations. When compared to simulation devices of the Psst. the greatest differences are that algorithm-based scenarios make scenario inputs unnecessary. and that the amount of work required for the point DB and single line diagrams were minimized.
