Purpose: A survey was conducted to investigate the role, priority, and awareness of physical therapists in the community care system for the elderly. Methods: Nine hundred ninety-three physical therapists were invited to an online survey from 1st to 30th June 2020. Results: While the awareness of physical therapists for the community care system for the elderly was found to be low, the role priority and performance ability were found to be high. Fall training scored the highest for the job duties of physical therapists, and functional training scored the highest for the performance ability of physical therapists. For the role priority by the education status regarding the community care system, the participants who received the education program showed higher scores in the performance ability than those who did not. For the role priority and performance ability according to the education levels, higher education levels resulted in higher scores in both outcomes. Regarding the clinical experience, low scores were found in the participants with less than five years of experience. Conclusion: Physical therapy establishes itself as an essential area of expertise in the community care system for the elderly. Therefore, these results can be utilized in developing a model for Korean community care for the elderly.

This qualitative study investigated different interaction patterns in an online discussion. The data was collected from asynchronous discussion occurred in a graduate course. The data analysis methods include inductive analysis and mapping strategy. The results of the study suggest three layers of interaction: response sequences, interaction amongst participants, and concept map of messages. The visualization of response sequences enabled the researcher to discover complex and dynamic interaction patterns amongst participants. The many-to-many communication feature of online discussion does not always enable direct one-on-one interaction between two participants. Rather, one message contributed to multiple threads in the stream of conversation. In terms of interaction amongst participants, the interaction amongst participants, as indicated in the data, the messages also bind each participant and consequently a group(s) of participants together. It appears that the contribution of one message may not only enable a response to one participant, but also connect many participants to each other. The concept map of messages proposes that response sequences and interaction amongst participants can also be viewed between concepts within messages in the discussion. On the surface, the messages posted by individuals are linked by the system in a linear fashion as they are posted. However, the interaction extends to collaborative conversation amongst participants. Ultimately, a conceptual network of interrelated ideas including multiple perspectives is built in asynchronous discussion.

Nowadays, the public as well as science educators pays much attention to the fourth industrial revolution and wonders what will happen to the societies in the future. Thus, this study aimed at predicting the education environment which will be brought from the fourth industrial revolution, and suggesting the solutions or tasks to be investigated in science education. Through the literature review, this study categorized the major changes of future society into a wild fluctuation of job market, the shift from possession-based economy to sharing economy, post-urbanized and distributed system, and the crisis of dehumanization. According to the four major changes, this study predicted the future environment that will occur to the educational system. First, the students should the competences necessary for the future and the school curriculum will be changed in terms of width and depth. Second, sharing economy may bring about the open platform similar to MOOC (Massive Open Online Course) or TED. Third, the manifestation of artificial intelligence in education will enable the individual and paced learning, and thanks to the change, the concept of distributed cognition will be more focused in education research. Fourth, the collaborative learning and character education should be more stressed to resist the dehumanization. This study suggests relevant tasks and issues that should be tackled for the successful change in primary and secondary schools.

Human Adaptive Mechatronics(HAM) is a new concept which was proposed in our university's research project sponsored by Japanese Ministry of Education, Sports, Culture, Science and Technology(MEXT), and is defined as "intelligent mechanical systems that adapt themselves to the user's skill under various environments, assist to improve the user's skill, and assist the human-machine system to achieve best performance". In this paper, the concept and key-items of HAM are mentioned. And the control strategy to realize a HAM human-machine system is explained in the case of physical-interface system, i.e. haptic system. The proposed assist-control of a force-feedback type haptic system includes online estimation of a operator's control characteristics, and a `force assist' function implemented as a change in the support ratio according to the identified skill level. We developed a HAM-haptic device test system, executed evaluation experiments with this apparatus, and analyzed the measured data. It was confirmed that the operator's skill could be estimated and that operator's performance was enhanced by the assist-control.

This paper is an overview of key elements of Korea National Open University's smart mobile learning system, and an attempt to evaluate its main services relative to the FRAME model and the Mobile Learning Development Model for distance learning in higher education. KNOU improved its system architecture to one based on xMOOC e-learning content delivery while also upgrading its PC-based online/mobile learning services to facilitate an easier and more convenient access to lectures and for better interactivity. From the users' viewpoint, the upgraded 'U-KNOU Campus' allows for a more integrated search capability coupled with better course recommendations and a customized notification service. Using the new system, the students can access not only the school- and peer-issued messages via online bulletin boards but also share information and pose questions to others including to the school faculty/officials and system administrators. Additionally, a new mobile payment method has been incorporated into the system so that the students can select and pay for additional courses from anywhere. In spite of these advances, the issue of device usability and content development remain; specifically U-KNOU Campus needs to improve its instructor-learner and learner-to-learner interactivity and mobile evaluation interface.

This study was conducted to explore the applicability and effects of Smart Support System for Creative Problem Solving(S3CPS) in engineering education. S3CPS is an online system developed to support learners' creative problem solving activities based on the CPS model proposed by Treffinger et al.(2000). In this study, it was applied in an engineering course in which students work in teams to design and produce creative robots with the purpose of verifying its effects on creative problem solving and team projects. To address the purpose, interviews and surveys were carried out to examine the effects of S3CPS. The qualitative data were analyzed through a generic coding process. Three ways to apply S3CPS in an engineering course based on team project were derived and effects of the system were also analyzed. It implies that specific design guidelines are required for the optimal use of the system for existing engineering courses.

Objectives: This study was aimed to develop a pharmacovigilance practice training course for future doctors of Korean medicine, the graduate students of a college of Korean medicine, and to verify the educational effect of the curriculum. Methods: Fifty-six students were given a training course designed as follows: 1) pre-class homework (basic theory self-study, online course, causality assessment, and adverse event reporting simulation); 2) in-class: homework submission and case discussion; 3) after-class: homework revision and resubmission. An online survey to assess the change of the level of basic knowledge and attitudes toward pharmacovigilance, the willingness to report adverse events, and self-efficacy for the causality assessment and adverse event reporting was conducted before and after education. Results: The survey participation rate was 96.5% in pre-education and 64.3% in the post-education survey. After education, knowledge level was improved (mean score from 4.3±2.11 to 6.7±1.96 points, modal value from 3 to 8 points) and positive changes were observed in almost all questions on attitudes. In the post-education survey, more students felt that they could do causality assessment (from 13% to 80.5%), could report adverse events to the agency in charge (from 7.4% to 96.2%), and expressed their strong willingness to report adverse events in the future (from 77.8% to 88.9%) than in the pre-education survey. Conclusions: More schools of Korean medicine need to adopt pharmacovigilance training courses in their curriculum to foster future doctors of Korean medicine with pharmacovigilance capabilities. Such efforts will be the basis for achieving an evidence-based, safe use of herbal medicine.
