With the development of media technology, virtual reality (VR) technology is widely used in education, medical care, aerospace, entertainment and other fields. Among them, application in teaching courseware is a relatively new topic. Compared with traditional coursewares, virtual games visualized and extruded abstract teaching contents. Thus it strengthened teaching effects and expanded dimensions of learning. We hypothesized that virtual coursewares could increase users'sense of presence and enhance their focus. In this study, virtual courseswares were compared with traditional coursewares. At the same time, its feasibility and advantages of application were analyzed through literature researching, practical researching and statistical analysis from questionnaires. Furthermore, we designed a teaching system for VR coursewares and explored its performance in multidimensional and contextual teaching situations. It was found that Virtual coursewares have changed the boring traditional teaching methods. The teaching content was displayed in the form of three-dimensional images, videos and sounds through VR equipment, which effectively improved teaching efficiency. In addition, the feasibility of virtual courseware was demonstrated through factor analysis in questionnaires. Compared with traditional teaching courseware, VR coursewares can attract students' attention and improve learning efficiency. It provides a good example and is valuable for the research of virtual realities in education.

The purpose of this study was to suggest instructional strategies applicable to Blended e-Learning. After examining how traditional universities utilized e-learning, it is attempted to have an interview with three working-level people and seven instructors, who widely applied e-learning to their classes. As a result, it is found that the instructors had some wrong understanding of e-learning, and their wrong perception was rooted in their lack of experience of providing e-learning and their reliance on fragmentary, superficial information. It deterred them from putting e-learning into active practice. Besides, it's additionally attempted to describe how blended e-learning could respectively be applied to different types of lectures, how to improve its social presence and how it could be used for evaluation

Lethargy in newborns usually indicates central nervous system dysfunction, and many conditions such as cerebrovascular events, infections, and metabolic diseases should be considered in the differential diagnosis. Nonketotic hyperglycinemia is an autosomal recessive error of glycine metabolism, characterized by myoclonic jerks, hypotonia, hiccups, apnea, and progressive lethargy that may progress to encephalopathy or even death. Cerebral sinovenous thrombosis is a rare condition with various clinical presentations such as seizures, cerebral edema, lethargy, and encephalopathy. Here, we report the case of a newborn infant who presented with progressive lethargy. An initial diagnosis of cerebral venous sinus thrombosis was followed by confirmation of the presence of nonketotic hyperglycinemia.

This study examined the moderating effect of course satisfaction with class on the relationship between the mode of course delivery and learning presence and performance in university settings. Results showed that there was a moderating effect of the course satisfaction on the relationship between course delivery mode and learning presence. Specifically, higher satisfaction with instructor's teaching activities was associated with improved learning presence in face-to-face, blended, and online learning, in that order. However, there was no significant moderating effect on academic performance. These findings suggest that universities should consider not only the mode of course delivery and highlight the importance of systematic course design by instructors.

Cutaneous leishmaniasis (CL) caused by Leishmania donovani is an endemic vector-borne disease in Sri Lanka. Over 2,500 cases have been reported since 2000 and the number of CL cases has dramatically increased annually. Total 57 clinically suspected CL patients attending the dermatology clinic in Anuradhapura Teaching Hospital were recruited from January to June 2015. Slit skin smears and skin biopsies were taken from each of the subjects. Clinical and epidemiological data were obtained using interviewer administered questionnaire. Forty-three (75.4%) patients among 57 were confirmed positive for L. donovani. The majority (77%) of infected patients was males, and the most affected age group was 21-40 years. Soldiers in security forces, farmers, and housewives were identified as high risk groups. The presence of scrub jungles around the residence or places of occupation (P=0.003), the presence of sandflies (P=0.021), and working outsides more than 6 hr per day (P=0.001) were significantly associated with CL. The number of lesions ranged from 1-3, and the majority (76%) of the patients had a single lesion. Upper and lower extremities were the prominent places of lesions, while the wet type of lesions were more prevalent in females (P=0.022). A nodular-ulcerative type lesion was common in both sexes. The presence of sandflies, scrub jungles, and outdoor activities contributed to spread of Leishmania parasites in an endemic pattern. Implementation of vector control programs together with health education with regard to transmission and prevention of CL are necessary to control the spread of this infection.

The purpose of this study was to identify factors influencing learning satisfaction of nursing students in online non-face-to-face classes during COVID-19 pandemic. 138 undergraduate nursing students were recruited from C nursing colleges of C city in Gyungnam. Data was collected using a self-reported online-questionnaire from 5 January to 18 January, 2022. Collected data were analyzed by SPSS/WIN 27.0 program using descriptive statistics, t-test, ANOVA, Pearson's correlation coefficient, and multiple regression. Factor influencing learning satisfaction among undergraduate nursing students on online non-face-to-face classes during COVID-19 pandemic were teaching presence(presence of teacher)(𝛽=.43, p<.001), instructional quality(content qualities)(𝛽=.41, p<.001), Satisfaction of nursing major(satisfaction)(𝛽=.13, p<.001). instructional quality(interface)(𝛽=.12, p=.036), which explained about 85.3% of total variance(F=192.78, p<.001). Therefore, in order to improve class satisfaction in online non-face-to-face classes, it is necessary to operate classes that prioritize the presence of teacher so that learners can recognize and trust the presence of teacher by passionately professional performing. And, among instructional quality, we should be strengthen the usefulness of learning materials, content factors related to tests and assignments, and strive to improve satisfaction of nursing major. In addition, it is necessary to prepare and operate classes that fully consider the interface factors related to the manual composition and system convenience for online classes among the quality factors of classes.

본 연구는 텍스트 중심의 연기론과 신체 중심의 연기론의 연결링크가 필요하다는 문제점을 인식하며 출발한다. 배우뿐만 아니라 연기교육자에 의해서도 수차례 논의되어 온 재현적 반복 연기를 통한 현존성 상실이라는 난제를 극복해줄 방안으로 브레히트의 연기론을 연구한다. 브레히트의 연기론은 많은 연구자들에 의해 종래의 배우훈련의 대안으로써 이미 언급된 바 있지만 실제 적용이 가능한 연기 훈련방법에 대한 연구는 많이 진행되지 않은 실정으로 브레히트 연기법의 실제에 대한 기초자료가 될 수 있도록 목표한다. 본 연구는 그 중에서도 텍스트 기반의 모순 찾기와 신체 중심의 브레히트 연기론을 연구하고 그의 연기론이 텍스트와 신체 중심 연기론의 연결링크로써 작용할 수 있는 가능성을 탐구한다. 연구방법으로는 먼저 텍스트 중심의 재현적 연기론과 신체 중심의 포스트드라마 연기론의 개념과 한계에 대한 이론적 고찰을 진행한다. 그리고 브레히트의 서사적 연기 중에서 텍스트에 중점을 둔 연기실행도구와 신체에 중점을 둔 연기실행도구를 구분하여 그가 사용한 용어와 개념을 정리하고 연기실행의 과정에서 도달하는 현존적 효과에 대해 확인한다. 마지막으로 필자의 지도경험을 바탕으로 브레히트의 연기이론을 변형하여 개발한 연기교수법 학습모형을 제안한다. 그러나 본 연구에서 제시한 학습모형은 필자의 지도경험만을 바탕으로 하기 때문에 그 효과를 일반화하는 데는 한계가 있음을 밝힌다. 향후 후속 연구를 통해 브레히트 연기론에 대한 깊이 있는 통찰과 다양한 연기교수법 모형을 개발을 통해 현대 연기교육의 다양성에 보탬이 되기를 기대해 본다.

Learning by teaching (LbT) has long been recognized as an important learning behavior that constructs meaning based on interactions between learners. This study aimed to explore the meaning of LbT as an important learning activity for future implementation in education. LbT is based on the cultural historical activity theory and sociocultural learning theory, as developed by scholars including Vygotsky. These frameworks value the construction of meaning based on language, and LbT is reported to be effective in constructing meaning. In addition, within the zone of proximal development posited by Vygotsky, learning through interaction between learners improves academic achievement, higher-order thinking, deep learning, and reflective learning. LbT also promotes students' learning presence, and strengthens various competencies such as collaboration and communication skills. Interactive behavior between learners in the form of LbT has been explored as an approach to teaching and learning, with methods including peer learning, peer tutoring, peer teaching, peer mentoring, Lernen durch Lehren, and peer-assisted learning. LbT has also been applied as a learning method. In the future, LbT has boundless potential to improve learning through activities such as flipped learning or online learning based on interactions between learners.
