The article highlights the problems of the digitalization of the educational process, which affect the pedagogical cluster and are of a psychological nature. The authors investigate the transformational changes in education in general and the individual beliefs of each subject of the educational process, caused by both the change in the format of learning (distance, mixed), and the use of new technologies (digital, communication). The purpose of the article is to identify the strategic trend of the educational process, which is a synergistic combination of pedagogical methodology and psychological practice and avoiding dialectical opposition of these components of the educational space. At the same time, it should be noted that the introduction of digital technologies in the educational process allows for short-term difficulties, which is a usual phenomenon for innovations in the educational sphere. Consequently, there is a need to differentiate the fundamental problems and temporary shortcomings that are inherent in the new format of learning (pedagogical features). Based on the awareness of this classification, it is necessary to develop psychological techniques that will prevent a negative reaction to the new models of learning and contribute to a painless moral and spiritual adaptation to the realities of the present (psychological characteristics). The methods used in the study are divided into two main groups: general-scientific, which investigates the pedagogical component (synergetic, analysis, structural and typological methods), and general-scientific, which are characterized by psychological direction (dialectics, observation, and comparative analysis). With the help of methods disclosed psychological and pedagogical features of the process of digitalization of education in a mixed learning environment. The result of the study is to develop and carry out methodological constants that will contribute to the synergy for the new pedagogical components (digital technology) and the psychological disposition to their proper use (awareness of the effectiveness of new technologies). So, the digitalization of education has demonstrated its relevance and effectiveness in the pedagogical dimension in the organization of blended and distance learning under the constraints of the COVID-19 pandemic. The task of the psychological cluster is to substantiate the positive aspects of the digitalization of the educational process.

본 연구에서는 정유사 탈황석고의 탄산화물 대체에 따른 ALC 제조 원료 적용 가능성을 검토하였으며, ALC 제조 실험을 통한 기초 특성 평가를 수행하였다. 탈황석고 및 탄산화물의 주성분은 CaO, SO₃등으로 나타났으며, 광물탄산화 반응에 따른 강열감량 증가를 확인하였다. 탄산화물의 결정상은 CaCO₃, CaSO₄, Ca(OH)₂ 및 CaSO₄·2H₂O로 나타났다. ALC 제조 원료인 탈황석고를 탄산화물로 대체할 경우 발포 높이 및 기공 형상은 모든 시편에서 유사하게 나타났으며, 절건 비중, 압축강도 또한 유사한 것을 확인하였다. 아울러 결정상 분석 및 미세구조 관찰을 통해 모든 시편에서 ALC의 주결정상인 토버모라이트 결정 생성을 확인할 수 있었다.

In this paper, a digitalization of Induction Motor Vector Control System is proposed, where all processings are executed by using a processor. In Vector Control System, where the motor voltages are controlled by using the motor voltage model, the variation of the rotor flux-interlinkage is very small however the deviation of the torque becomes large. Thus, in order to enhance the torque performance, voltage model based vector control scheme with minor current loops, which can eliminate the high frequency current harmonics is used.

Thesis is very valuable primary and secondary infomation resource in that it contains systematic research methods, comprehensive and detailed data, and creative research results in specific areas. But thesis has been neglected in many libraries and information centers due to the problems of accessibility and obtainabiliy problems as one of a Grey Literature. As information technology and networks have been developing rapidly, the digitalization of thesis full-text and the possibility of online access arc also increasing. In this study, value and the characteristics of thesis is firstly reviewed. Secondly, by analyzing the current digitalization state of some domestic and foreign universities and institutions, some principles for the effective electronic transmission and effective management of thesis are suggested as one of knowledge management. Furthermore useful information is suggested for the users in terms of the online access and obtainability.

Fuse is the initial equipment of Protective Relay The installation standard of Fuse has been used for long time in Power Facilities. However according to the innovative development of Electric & Electronic element(=semiconductor) Technology, Protective Relay and other Power Equipments are being changed into Digitalization and Multi-Functional Convergence. In contrast with it, the installation standard of Fuse is just the same. There is a need to give careful consideration to it. This study will bear a Part of producing a safe and efficient Power by examining the current installation of primal 8f secondary 1'use in multi-functional PT of Power plant, giving a problem careful consideration and suggesting suitable countermeasures.

Recently, welding technology of nonferrous metals which were difficult to implement by arc welder has become available through digitalization of arc welding machine. Among them, the welding quality improvement of aluminum welding is very noticeable. These results increase the arc stability by controlling arc current and voltage waveform precisely, and control wire feed speed by synchronizing with arc current which the feed rate of filler wire is controlled by a precise motor control of servomotor and not by a simple constant speed feeding. Not only through the hardware digitalization of arc welding machine but also through advance of software of arc welding, it became possible to implement a certain level of welding quality by a simple operation. These led to CMT welding process implementation which requires low heat input than current arc welding and highly increased the applicability of the aluminum welding.

Many system devices for fluoroscopic and general X-ray studies in diagnostic radiographic system have been being changed from analog mode to digital mode. In addition, among diagnostic imaging and radiologic examinations, fluoroscopic studies that requires functional diagnosis is being widely used. The video recording method of fluoroscopic studies has been useful in functional image diagnosis and dynamic image observation, but the utility of its image quality is being reduced because of limitation in setting play segments of the video player, inconvenience of play, difficulties in preserving reproduced images, the change of image quality, etc. In order to complement these shortages, it is necessary to facilitate access to patient diagnosis information such as storing, editing and sharing functional diagnosis images in response to the trend of the digitalization of digital radiographic & fluoroscopic system(DRF). Thus this study designed and implemented a device of storing functional dynamic images real time using a computer rather than existing video recording, aiming at contribution to functional image diagnosis.
