This study deals with the case of online-based project learning, which was designed for the purpose of university educational innovation and enhancing learners' competencies required by society, operated during the COVID-19 pandemic. The course was applied Python programming language, team-based project learning, and intensive course system, which is required by our society and companies in the era of the 4th industrial revolution. Also it was operated as a non-face-to-face online class, which would have been operated in an offline class if it had not been for Covid 19 pandemic, to explore the possibilities and educational effects of online learning. To do this, 32 university students participated in online-based project learning during 8 weeks, and then conducted a survey. The survey results were analyzed in terms of i) non-face-to-face online learning, ii) team-based project learning, and iii) application of the intensive course system. Results say that most of the learners were satisfied with the online learning, team-based project learning, and the intensive semester system applied in this course at a high level, and also they clearly presented the reasons. Thereby, it has been confirmed that the learners were already well aware of the pros and cons of each learning method. Based on these results, the implications were discussed.

Purpose: This research is a case study on a problem-based learning (PBL) model with blended learning in a nursing college. Methods: The target students were nursing sophomores in a nursing college who agreed to participate in a blended learning course and to be subjects in this study for 15 weeks. The questionnaires developed by Baek (2003) and Lee (2007) were modified and applied to collect data. Results: The students' satisfaction with the blending learning was the highest in the item "Online community activities were helpful in enhancing knowledge." The level of satisfaction with PBL was the highest in the item "It was helpful to listen my classmates' opinions rather than thinking all by myself." Conclusion: This study is suggestive that blended learning is effective to improve learning satisfaction by reinforcing practicality of face-to-face study to online learning. Various learning methods based on students' demands and preferences should be applied in nursing education.

Case-related news filtering is crucial in legal text mining and divides news into case-related and case-unrelated categories. Because case-related news originates from various fields and has different writing styles, it is difficult to establish complete filtering rules or keywords for data collection. In addition, the labeled corpus for case-related news is sparse; therefore, to train a high-performance classification model, it is necessary to annotate the corpus. To address this challenge, we propose topic-enhanced positive-unlabeled learning, which selects positive and negative samples guided by topics. Specifically, a topic model based on a variational autoencoder (VAE) is trained to extract topics from unlabeled samples. By using these topics in the iterative process of positive-unlabeled (PU) learning, the accuracy of identifying case-related news can be improved. From the experimental results, it can be observed that the F1 value of our method on the test set is 1.8% higher than that of the PU learning baseline model. In addition, our method is more robust with low initial samples and high iterations, and compared with advanced PU learning baselines such as nnPU and I-PU, we obtain a 1.1% higher F1 value, which indicates that our method can effectively identify case-related news.

Purpose: The purpose of this study was to investigate the effects of case-based learning (CBL) on learning motivation and learning satisfaction of nursing students in a human physiology course. Methods: The development and application of CBL scenarios was conducted from February to June, 2013. Nursing students (n=142) who registered for a human physiology course were assigned into either a control or CLB group. The control group received traditional lectures for 14 weeks. The CBL group received the same 14-week lectures and an additional 5 CBL sessions. The learning motivation and satisfaction were measured by questionnaires at the beginning and the end of the semester. Seven students in the CBL group were randomly selected for a focus-group interview. Quantitative data were analyzed by ${\chi}^2$-test and t-test, and qualitative data were analyzed by content analysis. Results: The learning motivation and learning satisfaction were not significantly different between the two groups. However, 59% of the CBL group answered with a positive impression on the CBL approach as it helped them to feel a sense of achievement, excitement, to form their identity as nursing students, and so on. Conclusion: These findings suggest that the CBL could be a challenging but useful learning method in a physiology course for nursing students. Further studies with guidance, such as instructors' questions and feedback design are needed to utilize CBL more effectively.

Since MegaStudy started e-learning business for Korean high school students, the Korean e-learning industry began to expand and steadily gain attention. This paper focused on the analysis of the development of the Korean e-learning business for teens and the growth of MegaStudy. The three institutional mechanisms were used to examine the factors that aided the development of the business. The regulatory mechanism was the government policy to prevent the expansion of the offline private education sector, which greatly aided the growth of the e-learning business. The mimetic mechanism was the notion to mimic the characteristics of the Korean e-business initiatives. The normative mechanism involved the widespread social norm suggesting that every student should be given an equal opportunity of private education. This paper also examined the case of MegaStudy as a successful case of the e-learning companies. It analyzed the business model of MegaStudy, which is based on its advantage as the front-runner and its high-quality contents and services.

Purpose: This study is know the home care nursing specialists' copying method for life-threatening emergency situation occurred while changing the tracheotomy tube in the patient's home through case-based learning. Methods: Two cases were analyzed using structured critical reflection while changing the tracheal tube. In the first case, the patient presented with dyspnea, cyanosis, and low oxygen saturation when connected to home mechanical ventilator after replacement of the tracheotomy tube. In the second case, replacement of the tracheal tube was difficult due to a narrowed airway from proliferated granulation tissue. Results: From the case-based learning. using a critical reflection instrument, home care nursing specialists indicated that it was important to explain the possibility of danger to the client and that nurses must check the operation of the ambu-bag to prepare for an emergency when replacing a tracheotomy tube. Moreover, they stated a need for two nurses during client visits when there is the possibility of an emergency. Conclusion: Case-based learning through critical reflection provides actual practice-focused knowledge that is helpful to home care nurse specialists who face emergency situations in a restricted environment. Therefore, we hope that home care nursing specialists will use this method to strengthen their professional knowledge.

The digital transformation and COVID-19 are also causing major changes in teaching-learning methods. The biggest change is the spread of remote training and the emergence of various innovative learning platforms. Distance education has been criticized for not meeting technology trends and field demands..However, the problem of distance education is being solved through a system that supports various interactions and collaborations and supports customized learning paths. The researcher conducted a case study on domestic and foreign learning platforms that provide non-face-to-face ICT education. Based on the case study results, the researcher presented the functional characteristics of a learning platform that effectively supports non-face-to-face learning. In common, these sites faithfully supported the basic functions of the information system. In addition to learning progress check and learning guidance, some innovative learning platforms were providing differentiated functions in practice support, performance management, mentoring, learning data analysis, curation provision, and CDP support. Most learning platforms supported one-way, superficial interaction. If the platform effectively supports a variety of learning experiences and provides an integrated learning experience thanks to the development of IT technology, user satisfaction with the learning platform, intention to continue learning, and achievement will increase.
