Artificial Intelligence has stimulated every aspect of today's life. Human thinking quality is trying to be involved through digital tools in all research areas of the modern era. The education industry is also leveraging artificial intelligence magical power. Uses of digital technologies in pedagogical paradigms are being observed from the last century. The widespread involvement of artificial intelligence starts reshaping the educational landscape. Adaptive learning is an emerging pedagogical technique that uses computer-based algorithms, tools, and technologies for the learning process. These intelligent practices help at each learning curve stage, from content development to student's exam evaluation. The quality of information technology students and professionals training has also improved drastically with the involvement of artificial intelligence systems. In this paper, we will investigate adopted digital methods in the education sector so far. We will focus on intelligent techniques adopted for information technology students and professionals. Our literature review works on our proposed framework that entails four categories. These categories are communication between teacher and student, improved content design for computing course, evaluation of student's performance and intelligent agent. Our research will present the role of artificial intelligence in reshaping the educational process.

Objectives: This study evaluates and recommends the priority of policy implementation to improve the fire protection clothing management system used by firefighters and the reduction of cross-contamination from contaminated clothing at the scene of a fire. Methods: It consisted of 7 experts and conducted three interviews and two modified Delphi surveys. Through the results of previous research and interviews with experts, a plan to reduce cross-contamination of fire suits and improve the management system was first derived. An improvement plan was presented in the four areas including resources, management, fire protection related work, and laws and regulations, and the priority of policy implementation was derived by analyzing the importance and practicality of the policy at the same time. Results: As a result of the analysis, the first priority was education on the health effects of pollutants at the disaster scene for firefighters, and the second priority was the addition of SOP for the primary decontamination of on-scene personal protective equipment in preparation for the health effects of the disaster scene, and education for fire suppression and rescue workers. The next step was to improve the management system of personal protective equipment such as fire suits and develop a training course for systematic operation. Conclusions: This findings could be used in the implementation of mid- to long-term firefighting policies for the systematic operation and establishment of a systematic management system for personal protective equipment such as fire protective suits.

Background Virtual education is an evolving method for teaching medical learners. During the coronavirus disease 2019 pandemic, remote learning has provided a replacement for conferences, lectures, and meetings, but has not been described as a method for conducting a cadaver dissection. We aim to demonstrate how learners perceive a virtual cadaver dissection as an alternative to live dissection. Methods A virtual cadaver dissection was performed to demonstrate several upper extremity nerve procedures. These procedures were livestreamed as part of an educational event with multimedia and interactive audience questions. Participants were queried both during and after the session regarding their perceptions of this teaching modality. Results Attendance of a virtual dissection held for three plastic surgery training institutions began at 100 and finished with 70 participants. Intrasession response rates from the audience varied between 68 and 75%, of which 75% strongly agreed that they were satisfied with the virtual environment. The audience strongly agreed or agreed that the addition of multimedia captions (88%), magnified video loupe views (82%), and split-screen multicast view (64%) was beneficial. Postsession response rate was 27%, and generally reflected a positive perspective about the content of the session. Conclusions Virtual cadaver dissection is an effective modality for teaching surgical procedures and can be enhanced through technologies such as video loupes and multiple camera perspectives. The audience viewed the virtual cadaver dissection as a beneficial adjunct to surgical education. This format may also make in-person cadaver courses more effective by improving visualization and allowing for anatomic references to be displayed synchronously.

Objectives : This study analyzed the concordance between student self-assessment and peer-evaluation in a role play using the Clinical Performance Examination (CPX) scenario developed based on Korean medical syndrome differentiation. Methods : The subjects of this study are first-year-students majoring in Korean Medicine. The role play based on clinical case was performed in the class of Korean Medicine Classics. Feedback on clinical skill competency got through student self-assessment and peer-evaluation, and this study was compared and analyzed of result. Results : A simple comparison of the results of self-assessment and peer-evaluation in the evaluation results of clinical skill competency may appear to be consistent. However, it was not statistically significant. It is necessary to enhance the discriminative ability in the evaluation of clinical skill competency. It will be possible to improve a bit by relatively increasing the weight of the scores on the items that students expect to respond differently among the evaluation items. In addition, in order to dramatically improve the systemicity and reliability of the evaluation of clinical skill competency itself, it is necessary to introduce the Introduction to Clinical Traditional Korean Medicine (ICTKM) course. Conclusions : Student's self-assessment and peer-evaluation as feedback on clinical skill competency are suitable for the purpose of education and training. However, the reliability of the evaluation was not statistically significant.

The rapid development of small-scale (1-10 MJ) Superconducting Magnetic Energy Storage Systems (SMES) can be explained by real perspective of practical implementation of these devices in electro power nets. However the serious problem of all high mechanically stressed superconducting coils-problem of training and degradation (decreasing) of operating current still exists. Moreover for SMES systems this problems is more dangerous because of pulsed origin of mechanical stresses-one of the major sources of local heat disturbances in superconducting coils. We investigated acoustic emission (AE) phenomenon on model and 0.5 MJ SMES coils taking into account close correlation of AE and local heat disturbances. Two-coils 0.5 MJ SMES system was developed, manufactured and tested at Russian Research Center in the frames of cooperation with Korean Electrical Engineering Company (KEPCO) [1]. The two-coil SMES operates with the stored energy transmitted between coils in the course of a single cycle with 2 seconds energy transfer time. Maximum operating current 1.55 kA corresponds to 0.5 MF in each coil. The Nb-Ti-based conductor was designed and used for SMES manufacturing. It represents transposed cable made of Nb-Ti strands in copper matrix, several cooper strands and several stainless steel strands. The coils are wound onto fiberglass cylindrical bobbins. To make AE event information more useful a real time instrumentation system was used. Two main measured and computer processed AE parameters were considered: the energy of AE events (E) and the accumulated energy of AE events (E ). Influence of current value in 0.5 MJ coils on E and E was studied. The sensors were installed onto the bobbin and the external surface of magnets. Three levels of initial current were examined: 600A, 1000A, 2450 A. An extraordinary strong dependence of the current level on E and E was observed. The specific features of AE from model coils, operated in sinusoidal vibration current changing mode were investigated. Three current frequency modes were examined: 0.012 Hz, 0.03 Hz and 0.12 Hz. In all modes maximum amplitude 1200 A was realized.

Objectives : We tried to propose the direction of Korean medicine education through the consideration of 'professionalism as a competency beyond knowledge-skill' that modern medicine should take and therefore the perspectives of the competency-based curriculum in Korean medicine education. Methods : Competency-based curriculum, professionalism education phase and competency at medical school, student demand survey, Korean medicine education Accreditation Standards, and related research articles were used. Results : Proposed development measures to cultivate students' professionalism in Korean medicine education are as follows. self-care and emotional stability programs, communications between patient and doctor and among the colleagues, career exploration programs based on global medical trends and government policy, standardized professional training programs, and the evaluation of teaching experiences and achievements. Conclusions : The main purpose of the reorganization of the competency-based curriculum should be for improving Korean medicine education. The contents of phase performance, process performance, and course performance should be carefully organized so that the core contents and spirit of traditional Korean medicine can be achieved. In modern medicine, education of professionalism has been used to cover the problems that arise from taking achievement goals only from a biomedical perspectives. Accordingly the education of professionalism is also important in Korean medicine education as the modern Korean medicine follows the aspect of modern medicine,
