In this study, we examined the cases of online video classes conducted under the COVID-19 situation for 46 first-year students majoring in electrical engineering at a 3-year college in Gyeongnam. The research was carried out according to the course development process so that classes could be conducted efficiently, focusing on electromagnetism(1) course in the second semester of the first year. The online class consisted of uploading PPT recorded videos and lecture materials to the LMS and giving assignments. The contents of the study were in the scope of examining learners' perceptions through online learning contents, assignment submission, mutual feedback between instructors and learners, university-level lecture evaluation, and free opinions on online video-based electromagnetism(1) classes. As a result of the study, it was confirmed that online lecture review and problem-solving are particularly important for understanding lecture materials, and also given the nature of engineering subjects that require plenty of mathematical expressions, the detailed and immediate feedback provided by instructor enhances learners' class satisfaction and understanding. Based on these, the direction of online classes to be developed after the COVID-19 pandemic and teaching and learning methods suitable for the characteristics of subjects were discussed.

The purpose of this study was to develop a high school home economics financial consumer education program based on backward design and validation by experts. The program was designed and developed by first selecting learning content elements through a review of existing research and an analysis of relevant literature. The next step was to categorize these elements into seven themes and apply the backward design instructional design model 2.0. The program was prepared in the form of a 21st teaching-learning course plan and workbook and was verified by nine home economics teachers with working experience in high school. The evaluation revealed that the average value for all questions was 3.81 (out of 4 points) and the CVR was .99, indicating that the program was valid. In addition, positive evaluations were received in terms of learning goals, content level, and learner participation by class. This study has significance in that a systematic financial consumer education program was developed by Education of Home Economics to improve the financial literacy of high school students. It can therefore be used as an elective course (mini-course) in Home Economics in the high school credit system. A follow-up study will be required to assess the improvement in financial literacy after implementing this program.

Ultrasound scanning of a peripheral nerve along its expected course is a simple and useful method for determining the cause of peripheral neuropathy. We present 3 cases of peripheral neuropathy in which the pathology was detected by simple ultrasound scanning of the affected nerve. There were 2 cases of entrapment neuropathy due to mucoid cyst and 1 case of nerve sheath tumor. All lesions were visualized by simple ultrasound scanning of the involved peripheral nerve. Our results suggest that if a lesion affecting the peripheral nerve is suspected after history and physical examination or electrophysiologic studies, ultrasound scanning of the peripheral nerve of interest throughout its course is very helpful for identifying the causative lesion.

Rupture of a bronchus is an unusual result of blunt trauma to the chest. We experienced a case of bronchial rupture caused by blunt chest trauma without external wound or rib fracture. This case was a 13 years old male who was elementary school student. He was compressed on anterior chest by basket ball goal post being failed down on the afternoon of admission day. After this accident, he was suffered from progressive dyspnea and chest pain. The bronchial rupture was confirmed by bronchogram, The operation was performed through standard posterolateral thoracotomy incision along the 5th rib course. The right upper lobe bronchus and intermediate bronchus was completely transected. The right upper lobectomy was done. The ruptured intermediate bronchus was connected direct simply. Post-operative course was uneventful. Thus we report this case of traumatic bronchial rupture with review of literature.

This study has explored the elements of e-teaching portfolio for enhancing teaching expertise in higher education. This study is carried out through the literature review and expert's focus group interview. As the result of this study, seven elements of e-teaching portfolio for enhancing teaching expertise in higher education have been found. First, 'personal background' include curriculum vitae, course responsibility, and other educational activities. Second, 'teaching philosophy' include the principals on teaching and learning, statements of teaching philosophy. Third, 'learning environment' include the characteristics of students, the previous learning contents, and physical environment. Forth, 'course contents and methods' include teaching strategies and instructional materials, Fifth, 'instructional evaluation' includes the principals of evaluation and the examples of learning outcomes. Sixth, 'endeavor for improvement of instruction' include evidence of activity for teaching improvement and instruction feedback from peer and students. And e-teaching portfolio also includes research career and awards history element.

The term megajournal is used to describe publication platforms, like PLOS ONE, that claim to incorporate peer review processes and web technologies that allow fast review and publishing. These platforms also publish without the constraints of periodic issues and instead publish daily. We conducted a yearlong bibliometric profile of a sample of articles published in the first several months after the launch of PeerJ, a peer reviewed, open access publishing platform in the medical and biological sciences. The profile included a study of author characteristics, peer review characteristics, usage and social metrics, and a citation analysis. We found that about 43% of the articles are collaborated on by authors from different nations. Publication delay averaged 68 days, based on the median. Almost 74% of the articles were coauthored by males and females, but less than a third were first authored by females. Usage and social metrics tended to be high after publication but declined sharply over the course of a year. Citations increased as social metrics declined. Google Scholar and Scopus citation counts were highly correlated after the first year of data collection (Spearman rho = 0.86). An analysis of reference lists indicated that articles tended to include unique journal titles. The purpose of the study is not to generalize to other journals but to chart the origin of PeerJ in order to compare to future analyses of other megajournals, which may play increasingly substantial roles in science communication.

The purpose of the study is to identify the influence of learning participation on learning outcomes in programming courses. Based on the literature review, learning participation is composed of three sub components: participation in preview, class, and review. Learning outcomes are categorized by academic achievement, learning satisfaction, and learning motivation. A survey was conducted with 267 students enrolled in programming courses from three IT departments at Myongji College. Findings revealed that participation in review and participation in class predicted all sub components of learning outcomes. Participation in review was found to have a greater effect on learners' achievement and participation in class was found to have a greater impact on learning satisfaction and motivation. However, the results showed that participation in class was not an influential factor for learning outcomes. Implications for enhancing learning participation and suggestions for future research are also discussed.

According to the participants, the current K-MOOC (Korean Massive Open Online Course) has a few problems, such as too few courses, low content quality, and useless learner management system compared to MOOCs abroad. These problems caused diminished learner motivation. Consequently, the K-MOOC service has recorded a low course completion rate despite high expenses spent to develop the contents and thus requires remedies to fix the issues. This study drew research subjects from a pool of college and graduate students representing the primary users of the K-MOOC. This study limited the research scope to the four categories: motivation, learning experience, recognition, and performance of the Biggs' 3P Learning System Model. Based on the literature review, ten variables were selected and explored how the subjects perceived four categories using the survey questionnaire. This study also examined the relationship between ten variables and generated suggestions for the instructors, course managers, and platform developers to make the K-MOOC better.
