Electronic educational environments in the conditions of quarantine restrictions of COVID-19 have become a common phenomenon for the organization of distance educational activities. Under the conditions of Russian aggression, Ukrainian proof of their use is unique. The purpose of the article is to analyze the role of electronic educational environments in the process of training applicants for higher education in Ukraine in the realities of a large-scale war. General scientific methods (analysis, synthesis, deduction, and induction) and special pedagogical prognostic methods, modeling, and SWOT analysis methods were used. In the results, the general properties of the Internet educational platforms common in Ukraine, the peculiarities of using the Moodle and Prometheus platforms, and an approximate model of the electronic learning environment were discussed. The reasons for the popularity of Moodle among Ukrainian universities are analyzed, but vulnerable elements related to security are emphasized. It was also determined that the high cost of Prometheus software and less functionality made this learning environment less relevant. The conclusions state that the military actions drew the attention of universities in Ukraine to the formation of their own educational platforms. This is especially relevant for technical and military institutions of higher education.

In subjects dealing with when historically important events took place, the application of memory laws can enhance the educational effectiveness. Methods to increase memory rate by applying additional information such as dots, lines, bars, etc. are being studied in numerical memory-based studies. This study proposes a method of applying the long-term memory mechanism that was lacking in the previous study. This is a mechanism that corrects the error data entered by user's mistake, and tries to increase the memory rate by giving a memorable effect. To this end, we propose the unique processes that are carried out in the mobile environments and we implement and evaluate the error correction numerical algorithms.

In the field of year-based interpretation of important data, memory laws can be used as a way to enhance educational effectiveness. Studies related to how to remember numbers are conducted in the form of increasing memory rates by presenting information in the form of conventional simple images. We attempt to supplement the method proposed in the paper of numerical algorithm for modifying errors based on mnemonic system in mobile environments. We want to complement the error correction numerical algorithm proposed in previous work. The study was a way to compensate the errors that occur when users enter numerical information in the apps they use. In this work, we want to increase the memory rate based on two-dimensional information by imposing the concept of angles, rather than simply showing data to help recall memories from mistakes. To this end, we propose a problem-solving process using developed app, and implement and evaluate the short distance valid algorithms.

The purpose of this study is to investigate the views on utilizing ICT material, especially the reasons for ICT material choice. Numerous recent studies have demonstrated increased use of electronic devices including smartphones in educational settings. But the reasons for using it as a learning tool have not been relatively researched from the point of view of pre-service teachers. Therefore, this study analyzed the pre-service teachers' thinking about utilizing ICT material and their learning experience. In that regard, data was collected in various ways such as surveys, interviews, and brief writings of participants. According to the study result, pre-service teachers were motivated in utilizing ICT material rather than text material. That is the reason why, as adult learners, especially pre-service teachers could be more motivated in self-directed learning environments. This study will be useful in considering ideas for the instructional design of pre-service teachers.

In introducing memory methods in various educational fields, programs in a mobile environment can be used for the purpose of increasing accessibility and enhancing the effectiveness of education. It is much easier to remember words with meaning than to remember numerical information such as years. From the standpoint of increasing the educational effect, the part that needs to be supplemented with the help of the application can be said to be numerical information. Most studies related to conventional numerical memory have focused on the form that helps memory by imaging numbers. In the paper on memory-based meta-record algorithms in the mobile environment, the application developed in the previous study attempts to supplement this by discovering and simply modifying the user's mistakes in the entered numerical information. In this study, we aim to increase the memory rate by constructing metadata based on personalized log information and correcting mistakes. To do this, applications suitable for the mobile environment are developed, a structure of meta-record data is proposed, and meta-record application algorithms are implemented and evaluated.

In order to construct a system for big data processing, one needs to configure the node by using network equipments to connect multiple computers or establish cloud environments through virtual hosts on a single computer. However, there are many restrictions on constructing the big data analysis system including complex system configuration and cost. These constraints are becoming a major obstacle to professional manpower training for big data areas which is emerging as one of the most important national competitiveness. As a result, for professional manpower training of big data areas, this paper proposes a Raspberry Pi Board based educational big data processing system which is capable of practical training at an affordable price.

Arduino is one of the commonly used microcontroller platforms, and widely used not only in education but also in industrial fields because it enables rapid development and has excellent expandability. However, since there are only a few microcontrollers officially used by Arduino, attempts have been made to use various microcontrollers in the Arduino environment. As part of the Arduino expansion, in this paper, we implemented 128duino, ATmega128-based Arduino-compatible board, and its operation was verified. ATmega128 is one of the microcontrollers commonly used for educational purpose, so it was chosen for Arduino expansion. Since 128duino has advantages in terms of hardware configuration and price by implementing serial and ISP style upload with one USB connection, it is expected to be used in various environments including Internet of Things as well as in education.

The purpose of this study is to propose a new teaching method of the digital logic circuit so that students can cultivate digital literacy in diversifying future educational environments. In this paper, we analyzed the previous studies related to teaching methods for Tinkercad and digital logic circuits and suggested how to apply Tinkercad to the specific instruction design of the digital logic circuit. In addition, after showing the class design using Tinkercad to the actual lessons, It turns out two significant facts in a survey: to create a circuit that can implement the operation of the basic gate and to make it easier to understand the principles of the basic gate. The teaching method suggested in this study can be informative for students to acquire basic knowledge of electricity and electronics. Since Tinkercad is an open software based on cloud systems that are used not only in Korea but also foreign countries, it can be utilized in the lessons of digital logic circuits in the near future.

As electronic environment is changed owing to the developments of computers and telecommunication technique, the meaning of working process is changed because individual working process is shifted to overall working process of each groups while main frame is transferred to server environments. By using groupware, productivity of office work's is increased not only quality matter but also quantity matter and rapid and various services are provided. In order to realize united office automation, when educational programs are assembled at office automation related departments in junior colleges, it will help to stress importance of groupware.
