This article examined the effects of self-reflecting journal writing in speaking class on academic performance of science and engineering students. To assess the effect, 27 science and engineering students from the "Speech and Life" class were asked to keep a self-reflecting journal. Pre and post-intervention surveys were conducted, followed by the analysis of learning effect and satisfaction. In addition to the pre and post-intervention surveys, an additional survey on speaking ability was conducted at the same time and the change of the students' ability was assessed. Results showed that after writing self-reflection journals, participants' learning effect and satisfaction has increased, and their speaking performance was also improved.

The goal of this study was to understand the reasons for learning about Korean herbal food by examining the actual conditions in a Korean herbal food course during lifestyle education. The general characteristics of the people learning about or working with the food as well as the correlations between the examined factors were analyzed, focusing on each person's dietary lifestyle. We divided the class participants into five dietary lifestyle groups by analyzing their scores. Group 1 was the"taste-seeking type", group 2 was the "quality-seeking type", group 3 was the"economy-seeking type", group 4 was the"convenience and economy-seeking type", and group 5 was the"convenience and health-seeking type". A person with a cooking career was considered to have more experience with Korean herbal food. The highest motivation for Korean herbal food education was for professional reasons, and the class that was most appreciated was learning about Korean traditional herbal foods. The highest satisfaction for the class was based on the instructor's knowledge, followed by food tastes, foodstuffs, educational materials, and the facilities superintendent. Satisfaction with the class tuition and practical utilization was relatively low.

To enhance customer satisfaction for higher profits, an e-commerce sector can establish a continuous relationship and acquire new customers. Utilize machine-learning models to analyse their customer's behavioural evidence to produce their competitive advantage to the e-commerce platform by helping to improve overall satisfaction. These models will forecast customers who will churn and churn causes. Forecasts are used to build unique business strategies and services offers. This work is intended to develop a machine-learning model that can accurately forecast retainable customers of the entire e-commerce customer data. Developing predictive models classifying different imbalanced data effectively is a major challenge in collected data and machine learning algorithms. Build a machine learning model for solving class imbalance and forecast customers. The satisfaction accuracy is used for this research as evaluation metrics. This paper aims to enable to evaluate the use of different machine learning models utilized to forecast satisfaction. For this research paper are selected three analytical methods come from various classifications of learning. Classifier Selection, the efficiency of various classifiers like Random Forest, Logistic Regression, SVM, and Gradient Boosting Algorithm. Models have been used for a dataset of 8000 records of e-commerce websites and apps. Results indicate the best accuracy in determining satisfaction class with both gradient-boosting algorithm classifications. The results showed maximum accuracy compared to other algorithms, including Gradient Boosting Algorithm, Support Vector Machine Algorithm, Random Forest Algorithm, and logistic regression Algorithm. The best model developed for this paper to forecast satisfaction customers and accuracy achieve 88 %.

Background: To survey and analyze awareness and recognition during a non-face-to-face lecture, and satisfaction with among dental technology students. Methods: Total 179 undergraduates were surveyed from the Department of Dental Technology. Frequency analysis, cross analysis, independent sample t-test, correlation analysis, and multiple regression analysis were used for analyzing statistics. Results: Overall satisfaction with the non-face-to-face lecture was the highest (p=.037) while watching a recorded lecture in the theory curriculum subject. In the case of practical subjects, satisfaction with face-to-face lectures appeared to be higher (p=.039) compared to non-face-to-face lectures. Factors influencing the recognition of non-face-to-face lecture quality included awareness of a place to conduct a class and of face-to-face delivered lecture quality, satisfaction with face-to-face lecture, and satisfaction with non-face-to-face lecture. Factors affecting satisfaction with a non-face-to-face lecture included a place to conduct a class, the most effective theory non-face-to-face class method, the method of having been experienced the most among non-face-to-face lecture methods, and the recognition of non-face-to-face lecture quality. Conclusions: Future educational environment should include combined face-to-face and non-face-to-face lectures. An efficient educational indicator will be needed to evaluate learners' assessments and opinions about online classes, followed by its application to teaching methods.

The aims of this study are to develop the STEAM program focused '3D printing for respiratory system' and to ascertain its influence on elementary student's science process skills, creative problem solving abilities and scientific interest. The developed STEAM program was applied to 5th grade students of O elementary school located in J city. As a result of applying the STEAM program, the experimental group of the STEAM program class improved significantly in creative problem solving abilities and scientific interest than the control group of the theoretical class. The result of learner satisfaction survey of the STEAM program was high. Meanwhile, there was no significant difference in science process skills between the two groups. Therefore, the STEAM program class with the theme of '3D printing for respiratory system' could be meaningful works to encourage students' interest as well as their creative problem solving ability and scientific interest. In future, continuous and systematic studies on STEAM programs focused on 'structure and function of our body' are needed for elementary students' cognitive and affective developments.

Purpose: We investigated the satisfaction of physical therapy course according to teaching ways after COVID-19. Methods: 336 students in major of physical therapy were recruited in this study. Based on the classification of subjects in the national examination, the questionnaire was divided into 6 subjects in the basic field of physical therapy, 2 subjects in the field of physical therapy diagnostic evaluation, 8 subjects in the field of physical therapy intervention, and 3 subjects in other fields. The Likert scale was used. Results: In the basic field of physical therapy, all subjects were shown the high score of the satisfactory in face-to-face classes except for the public health and medical law compared to the non-face-to-face classes and mixed classes. Regarding the field of physical therapy diagnostic evaluation, the principle of diagnostic evaluation was shown the high score of the satisfactory in face-to-face classes compared to the non-face-to-face classes and mixed classes. In the field of physical therapy intervention, all subjects were shown the high score of the satisfactory in face-to-face classes compared to the non-face-to-face classes and mixed classes. Conclusion: We found that the face-to-face classes in most of subjects was shown the high score of satisfactory. We believed that our results can be used as basic data for physical therapy major learning methods.

본 연구는 온라인으로 진행된 두경부 해부학 수업을 수강한 학습자를 대상으로 온라인 강의에 대한 만족도를 조사하고, 지속적으로 진행될 수 있는 온라인 수업에서 더 좋은 교육 효과를 얻기 위한 기초자료를 마련하기 위해 수행되었다. 두경부 해부학 온라인 수업을 수강한 치위생학과 학생 120명을 대상으로 온라인 강의를 수강하는 시간과 온라인 강의 유형을 조사하였다. 수업 이해도와 학업성취도를 주관적으로 평가하도록 하였으며, 온라인 강의의 학습몰입도, 온라인 강의 만족도에 영향을 미치는 요인을 분석하였다. 학업 성취도가 증가할수록 학습 몰입도가 증가하였으며, 과제 시간이 줄어들수록 학습 몰입도가 증가하였다. 수업이해도가 높아질수록 온라인 수업 만족도가 증가하였으며, 과제 시간이 증가할수록 온라인 수업 만족도는 감소하였다. 본 연구의 결과가 포스트 코로나 시대를 맞아 해부학 분야의 새로운 교육과정을 설계할 때 그 방향을 비추는 역할을 할 수 있기를 기대한다.
