With the coronavirus outbreak in China at the end of 2019, a global pandemic, most universities held non-face-to-face classes in the spring of 2020. One of the difficulties experienced by universities that abruptly conducted non-face-to-face education was management of the quality of education. Therefore, this study compared and analyzed how the existing indicators used to measure the quality of education in a non-face-to-face education environment changed. The results of the survey on the degree of adaptation and satisfaction of the lecture held at Handong University in the spring of 2020 were compared and analyzed with the previous data of the same lecturer. Overall, both class adaptation and satisfaction scores were found to be similar or slightly higher than before. Compared to lectures conducted by uploading recorded lectures, lectures conducted in real time had higher scores on all satisfaction survey questions. There was no significant change in satisfaction depending on the number of participants and the teacher's previous online lecture experience.

One of the most important factors for the clinical success of adhesive posterior restorations is marginal adaptation. This property is very closely related to mechanical properties and to the shrinkage behavior of composite materials. Most of modem composite materials are light-cured. This is why the first part of this lecture will be confined to our recent research on light curing, such as plasma polymerization, LED polymerization and the power of modem halogen lamps. In the second part of the lecture the shrinkage properties such as dimensional shrinkage and shrinkage forces of different light curing materials and during different curing procedures will be discussed. Finally, in the third part of the lecture, marginal adaptation before and after loading in different cavity classes and by using different restorative techniques and curing procedures will be presented. Data will also be given on wear resistance, abrasiveness against opposing cusps and postcuring of composite materials.(omitted)

Objectives: The purpose of the study was to investigate the satisfaction with instruction medium according to learner attitude and lecture mode in the dental hygiene students. Methods: A web-based self-reported questionnaire was complected by 155 dental hygiene students in Cheonan from May 26 to June 5, 2015. The questionnaire consisted of general characteristics of the subjects, school adaptation, interest to learn, effort to learn, faculty centered lecture, learner centered lecture, self-directed learning, motivation to learn, characteristics of each subject, and satisfaction with lecture mode. The study was approved by institutional review board (IRB) by Baekseok University. Chi-square test and multivariate logistic regression were used to evaluate the satisfaction to medium of instruction according to explanation factors. Results: The lecture mode, opportunity and motivation to learn, interest to learn and effort to learn were the significant factors to satisfaction with instruction medium. In multivariate logistic regression model, the adjusted odds ratio was 6.28 for the opportunity to learn and 4.87 for the interesting to learn. Conclusions: The satisfaction with instruction medium is the most important factor that decides the lecture mode and learner attitude including opportunity to learn and concern to learn.

Purpose: This study proposed to examine the effects of a blended-learning orientation program executed for nursing students' clinical practice. Method: The participants were 61 nursing students in the experimental group and 57 in the control group. For the experimental group, a blended-learning orientation program was executed by e-learning (on-line) and lecture-led training (off-line) from two-week before the start of clinical practice in medical-surgical nursing. For the control group, orientation was given in the traditional lecture-led training by distributing printed materials before clinical practice. A pre-test was conducted on the experimental and control group before clinical practice, and a post-test was conducted after two-week of clinical practice in order to examine the effects of the orientation program. Results: After two-week of clinical practice, differences were observed between the experimental group and the control group in adaptation to clinical practice (F=10.242, p=.002), communication skills (F=4.305, p=.040) and clinical competence (F=6.823, p=.010). Conclusions: The blended-learning orientation program enhanced nursing students' adaptation to clinical practice, improved their communication skill and increased their clinical competence. Accordingly, it is recommended to develop and apply practical education using blended-learning in the area of nursing science.

The purpose of the research was to find out the difference in students' academic achievement in Technology Education between students with a lecture, those who perform a content-related project after a lecture, and those who carry out a content-related project without a lecture. The results of this study are as follows. First, taking advantage of both a lecture and project-based lesson led to better achievement than using only a project in Technology Education subject of an academic high school in academic achievement in 'knowledge' area. I infer that it is because they reviewed what they had learned in a lecture and the preparation and practice of the project caused them to memorize it. Second, there was not a meaningful difference in academic achievement in 'understanding' area among the group with a lecture, the one with both a lecture and a project, and the one with only a project. However, considering the comparison of averages and the p-value of F-test, I can deduce that the test outcome influences students with a lecture and a project positively in terms of academic achievement. Third, there was not a meaningful difference in the academic achievement in 'adaptation' area among the group with a lecture, the one with a lecture and a project, and the one with a project. I can conclude that those results are because the difficulty level of evaluation was high and they produced a model just by copying textbook contents.

The advent of BIM(Building Information Modeling) design process based on the digital media has brought innovation to the production and management of AEC industry. Accordingly the need for educating BIM professionals has been radically increased both in the real world practice and in academia. Some developed countries have already been studying and establishing the optimized curriculum in the academic architecture courses for BIM based education with multi_efforts using the digital media as design processing tools focused on educating architectural professionals with creativity and productivity. However in the domestic education systems, it is hardly found that researches and curriculums deal with the BIM education in the academia. Thus the objective of this paper is to investigate the architectural design pedagogy in the advanced digital media setting in response to the urgent need for BIM education. This study focuses on developing the curriculum based on practical adaptation of BIM programs for architectural education. It aims to provide students with the basic understanding of BIM theory and the practice of BIM tools as an instrument enhancing the creativity for architectural design. Thus this study proposes an BIM curriculum for the students who first encounter the notion and knowledge of BIM during their academic years. And the education result after the application of this curriculum has been analysed through the students questionnaires before and after the lecture.

During the 20th century, humankind went through the most significant changes in history, from industrial and agricultural revolutions to the invention of the personal computers and the internet, and changes continue to come at an even faster rate. One of notable change is emerging multicultural societies. People tended to live in a monocultural society and new cultures were infused in controlled and confined manners, however, people now live and eat in a continuously changing multicultural society Multicultural societies are emerged from the translocation of people (immigration) and, in a larger sense, globalization. Immigrants are faced with various and different cultures from their own, resulting in excitements and agonies in finding balance among many cultures. People who have not translocated themselves must also deal with various imported foreign cultures from fastfood restaurants to food beliefs. This lecture will use Korean Americans as an example to discuss how immigrants navigate different cultures and environments and how acculturation, the process of adaptation, affects their diet and health. In addition, how globalization has changed people's eatery will be briefly discussed. Understanding impacts of living and eating in a multicultural society is meaningful and useful to find effective approaches to promote healthy lifestyles to people in this fast changing times.

A comprehensive mapping project for agroclimatic zoning in South Korea will end by April 2010, which has required 4 years, a billion won (ca. 0.9 million US dollars) and 22 experts from 7 institutions to complete it. The map database from this project may be categorized into primary, secondary and analytical products. The primary products are called "high definition" digital climate maps (HD-DCMs) and available through the state of the art techniques in geospatial climatology. For example, daily minimum temperature surfaces were prepared by combining the climatic normals (1971-2000 and 1981-2008) of synoptic observations with the simulated thermodynamic nature of cold air by using the raster GIS and microwave temperature profiling which can quantify effects of cold air drainage on local temperature. The spatial resolution of the gridded climate data is 30m for temperature and solar irradiance, and 270m for precipitation. The secondary products are climatic indices produced by statistical analysis of the primary products and includes extremes, sums, and probabilities of climatic events relevant to farming activities at a given grid cell. The analytical products were prepared by driving agronomic models with the HD-DCMs and dates of full bloom, the risk of freezing damage, and the fruit quality are among the examples. Because the spatial resolution of local climate information for agronomic practices exceeds the current weather service scale, HD-DCMs and the value-added products are expected to supplement the insufficient spatial resolution of official climatology. In this lecture, state of the art techniques embedded in the products, how to combine the techniques with the existing geospatial information, and agroclimatic zoning for major crops and fruits in South Korea will be provided.
