Non-face-to-face classes continue due to Covid-19. There have been e-learning classes since the past, but the difference is that the current non-face-to-face classes are blended classes that combine real-time and recording classes or combine face-to-face and non-face classes. It is also characterized by being able to self-filmed or choose various lecture platforms in a place other than a dedicated studio. The advantages of non-face-to-face classes can be learned beyond time and space, and repetitive viewing and learning speed can be adjusted. Greening classes have no time and place constraints, and real-time classes have the advantage of high communication effects with learners. Evaluating whether non-face-to-face classes provide sufficient quality compared to face-to-face classes or e-learning will be necessary if branded classes are considered for post Covid. In this paper, for the evaluation of the service quality of non-face-to-face classes, the essential attributes desired by the instructors were derived from the viewpoint of Kano quality attributes and a quality improvement plan was proposed. After expressing the degree of functions that non-face-to-face classes should have on the X-axis and the satisfaction of learners on the Y-axis, 23 quality attributes were classified into 6 quality dimensions. In addition, satisfaction coefficient, dissatisfaction coefficient, and customer satisfaction improvement index were derived. As a result, 50% of learners were satisfied with non-face-to-face classes, but the preference was slightly higher than satisfaction, suggesting the sustainability of non-face-to-face classes. In terms of the customer satisfaction improvement index, the ranking of attributes with the largest increase in satisfaction when improving class quality was as follows. Professors' quick answers to learners' questions, content that can fully explain the subject, what the professor explains easily, develop high-quality content that can be learned on mobile phones, fairness of attendance checks, and real-time classes should start on time.

Basic nursing core skills are the essential skills required of nurses to effectively care for their patients. This study introduces an on-campus practicum using a mobile-based reflective journal, and attempts identify the challenges faced by students when performing core clinical nursing skills. The on-campus practicum was operated based on Kolb's experiential learning cycle. For each class, students used mobile devices to write an online reflective journal. Analyzing contents of the reflective log helped in identifying difficulties experienced in executing core skills, and classifying them in terms of knowledge, skill, and attitude. The level of difficulty, importance, and confidence in the core clinical nursing skills were also assessed. Students were found to be struggling with various aspects of performing core nursing skills, especially in the skill category. Students also showed a lack of confidence in items they perceived as "high" difficulty, such as IV injection and indwelling catheterization. Moreover, over 50% students considered IV injection and vital sign checking as the most important core clinical nursing skills. Our data suggests the necessity to develop various contents and apply instructional strategies to solve the core skills difficulties faced by nursing students, and to continuously generate evidence for the same.

This study was a pilot test of serious educational game content(named Roly Poly 160) designed to enhance self-care by elderly diabetics. Roly Poly 160 was developed in eight steps (literature review, demand survey and consultation, extraction of serious content using games, development of Roly Poly 160, pretest for users, workshop for health care workers, final completion of Roly Poly 160 and user satisfaction survey of Roly Poly 160). Roly Poly 160 is intuitively structured in three modules (self-management, card games, and quiz games) that can be self-managed by the elderly and is designed based on six principles. First, we constructed an intuitive interface considering the age of users. Second, the menu was selected as the main menu for Koreans and calorie learning was made at the same time. Third, the calories and nutrients (carbohydrate, fat, protein, calcium, sodium) of selected foods are analyzed, and all test data recorded in the questionnaire chart are graphically displayed by year, month and week so that the change trends can be grasped at a glance. Fourth, necessary data were saved and output and used as educational data. Fifth, user data are made compatible and aggregated and up to 100 million members can be registered. Sixth, it is designed to be developed as a mobile app if necessary. Using Roly Poly 160, 119 diabetic patients were diagnosed with diabetes, and the satisfaction score was 4.26 out of 5. These findings indicate that Roly Poly 160 is appropriate as a diabetes self-care tool and suggests that there is a possibility to use it as a program to educate people about diabetes in public health centers, hospitals and clinics.

Problems caused by malicious comments occur on many social media. In particular, YouTube, which has a strong character as a medium, is getting more and more harmful from malicious comments due to its easy accessibility using mobile devices. In this paper, we designed and implemented a YouTube malicious comment detection system to identify malicious comments in YouTube contents through LSTM-based natural language processing and to visually display the percentage of malicious comments, such commentors' nicknames and their frequency, and we evaluated the performance of the system. By using a dataset of about 50,000 comments, malicious comments could be detected with an accuracy of about 92%. Therefore, it is expected that this system can solve the social problems caused by malicious comments that many YouTubers faced by automatically generating malicious comments statistics.

Context-aware adaptive service for overcoming the limitations of wireless devices and maintaining adequate service levels in changing environments is becoming an important issue. However, most existing studies concentrate on an adaptation module on the client, proxy, or server. These existing studies thus suffer from the problem of having the workload concentrated on a single system when the number of users increases md, and as a result, increases the response time to a user's request. Therefore, in this paper the adaptation module is dispersed and arranged over the client, proxy, and server. The module monitors the contort of the system and creates a proposition as to the dispersed adaptation system in which the most adequate system for conducting operations. Through this method faster adaptation work will be made possible even when the numbers of users increase, and more stable system operation is made possible as the workload is divided. In order to evaluate the proposed system, a prototype is constructed and dispersed operations are tested using multimedia based learning content, simulating server overload and compared the response times and system stability with the existing server based adaptation method. The effectiveness of the system is confirmed through this results.
