The CanSat was designed as an educational satellite simulation program that implements the overall system of the satellite such as the command processing unit, the communication unit, and the power unit in a structure of the size of a can. In particular, the training effect is very excellent because the trainee can learn a process similar to the actual satellite development process by designing, manufacturing, testing, and launching. Republic of Korea Air Force Academy has been using the CanSat production kit used by the domestic can satellite contest experience department for education, but since it was produced based on PCB, it was impossible to show creativity and operation was restricted even with small mistakes. In this paper, we analyze the existing CanSat kit and propose a new educational CanSat kit that can be used in creative engineering design and practice subjects that will be reorganized into a regular course from 2021, and a lesson plan. In conclusion, by using the proposed CanSat kit for lectures, it is possible to achieve educational purposes and effects, improve lecture satisfaction, and provide stable instruction.

Purpose: This study was conducted to develop Web-based multimedia contents for supporting student nurses' clinical practice on critical care, and to evaluate learners' responses. Methods: Based on the steps of Assessment, Design, Development, Implementation, & Evaluation(ADDIE) model, a total of 13 self-directed learning modules including live lectures and real video clips were developed through faculty collaboration of nine nursing colleges in Gwangju and Chonnam province. The finally developed multimedia contents were published on the Web of the learning management system at a local e-learning center. Results: The Web contents were evaluated after self-learning by 81 junior college nursing students who were encouraged to study it at their own pace during their two-week clinical practice at a medical or surgical intensive care unit of a university hospital and two hospitals. The knowledge (t = -27.66, p < .001) and self-evaluated clinical performance level(t = 7.54, p < .001) were significantly increased after learning of the Web contents and clinical practice, and satisfaction level that measured post-test only was 4.0 out of 5 point. Conclusion: The use of Web contents for critical care need to be extended as a complimentary material in a class room lecture or clinical practice of students to increase their self-learning ability and understandings of clinical knowledge and situation.

Sentiment analysis is one of the promising approaches for developing a point of interest (POI) recommendation system. It uses natural language processing techniques that deploy expert insights from user-generated content such as reviews and feedback. By applying sentiment polarities (positive, negative, or neutral) associated with each POI, the recommendation system can suggest the most suitable POIs for specific users. The proposed study combines two models for POI recommendation. The first model uses bidirectional long short-term memory (BiLSTM) to predict sentiments and is trained on an election dataset. It is observed that the proposed model outperforms existing models in terms of accuracy (99.52%), precision (99.53%), recall (99.51%), and F1-score (99.52%). Then, this model is used on the Foursquare dataset to predict the class labels. Following this, user and POI embeddings are generated. The next model recommends the top POIs and corresponding coordinates to the user using the LSTM model. Filtered user interest and locations are used to recommend POIs from the Foursquare dataset. The results of our proposed model for the POI recommendation system using sentiment analysis are compared to several state-of-the-art approaches and are found quite affirmative regarding recall (48.5%) and precision (85%). The proposed system can be used for trip advice, group recommendations, and interesting place recommendations to specific users.

This study was designed to set up more developed curriculum in Nursing department of a junior college. The sample for the study were fifteen curriculums of fifteen selected junior colleges in Seoul and Kyunggi area. The credits and hours of each curriculum were analyzed into means and compared with the one of the example college. The data were categorized into seven sections; cultural subject, basic medical science, major subjects such as Nursing, Fundamental Nursing, electives, teaching and non-teaching subjects, and clinical practice. The data were analyzed by means of descriptive statistics. The results of the study were as follows; 1. Credit hours of Cultural subjects of each college ranges from $5.8\%\;to\;25.7\%$ of the total graduate credit hours; most commonaly lectured subjects are English 05 colleges), Korean (11 colleges), psychology (10 colleges), and computer (10 colleges). 2. In the case of the example college, Anatomy and Psychology were jointed as one subject, Basic Nursing Science, and some more study in depth should be made to develop more of this type of conjunction among related subjects on basic medical science. 3. As for the mendatory subjects of the example college, subjects on Adult Nursing was fourteen credits (14 hours), which was higher than the average 12.9 hours of other colleges compared. 4. Credit hours of Basic Nursing Laboratory were eight to ten credits (12-18 hours), which was higher than actual class hours. As more and more hospitals test clinical aptitude when recruiting nurses, more emphasis should be paid to the clinical practice. 5. Among fifteen sample curriculums six to twelve electives were offered with twelve to twenty-three credits. Most commonly opened subjects were Physical Examination (5), Nursing English (14). and Geriatrics Nursing (13). Nursing English are considered to be more important in the view of clinical practice. and Oriental Nursing, Nursing Information and Health Insurance Management should be considered as specialized subjects. 6. Teaching and Non-teaching subjects In case of the example school. Clinical Emergency Medicine, Introduction to Emergency Medicine were offered for these non-teaching class students so they could prepare for the qualification examination. 7. Clinical Practice The average credit hours for clinical practice of the sample college were 20.9 credit hours $(66.5\%)$ and the example school offered twenty credit hours which was slightly lower than the other forteen.

One challenge with teaching practical programming classes is the standardization of development tools on student computers. This is particularly true when a complicated setup process is required before beginning to code, or in remote classes, such as those necessitated by the COVID-19 pandemic, where the instructor cannot provide individual troubleshooting assistance. In such cases, students who encounter problems during the setup process may give up on the class altogether before even beginning to code. Therefore, this paper recommends using GitHub Codespaces as a tool for implementing standardized student development environments from day one. Codespaces provides Docker containers that an instructor can configure in such a way as to enable students to practice installing various coding tools within a controlled space, while also providing a language-specific, fully optimized development environment. In addition, Codespaces may be used more effectively in collaboration with GitHub Classroom, which helps instructors manage both the starter code and coding environment in which students work. In this paper, we compare two semesters of university Node.JS programming classes that utilized different development environments: one localized on student computers, the other containerized in Codespaces online. Then, we discuss how GitHub Codespaces and GitHub Classroom can be used to increase the effectiveness of practical programming classes while also increasing student engagement and programming confidence in class.

본 논문은 멀티미디어 교육자료와 전통적 수업방식의 효과성을 실질적으로 검증하고자 전문계 고등학교의 수업 방법을 비교분석하였다. 실업계의 전문교과 중 유통관리실무과목을 학습내용으로 선정하고, 멀티미디어 교육자료를 MS파워포인트로 디지털화하였다. 이를 위하여 30명의 학생들을 각각 실험집단과 통제집단의 표본집단으로 하고 동질성과 학업성취도를 고려하여 구성하였다. 동일한 교사가 두 집단을 같은 자료로 가르쳤다. 차이점은 두 집단간의 전달방법인데 두 유형의 교수방법으로 학습효과성과 만족도를 분석하기 위하여 사후검증을 실시하였다. 방법은 사전검사 점수를 공변인으로 통제한 후, 학생들의 학업성취도 사후검사 점수를 종속변인으로 공변량분석을 수행하였으며, 결과는 집단 간에 통계적으로 유의미한 차이가 있었다.(F=5.06, p<.05). 그것은 멀티미디어 교육자료를 활용한 수업의 학업성취도가 교과서 위주의 전통적 설명식 수업보다 더 높은 것으로 나타났다. 수업방식에 대한 만족도는 실험 통제집단 검증에서 통계적으로 유의미한 차이가 나타났다(t=5.65, p<.001). 따라서 멀티미디어 교육자료를 활용한 실험집단의 수업방식이 전통적 수업방식을 적용한 통제집단 보다 수업성취도와 만족도 측면에서 더 높은 것으로 나타났다.
