The development of personal computers and the Internet led to changes of instructor-student and student-student relationships in design education. New resources of design education with proper materials and tools have to be offered for teaching and learning. The purpose of this research is to develop Basic Graphic Tools(BGTs) on screen that help students to practice the design principles, and to evaluate the BGTs' usability to enhance the credibility of extra tools for online design learning. The BGTs has to be developed to minimize the gap between the online and traditional classroom settings and to maximize the diverse advantage of lecture content driven from technology. Students were given certain design requirements to explore BGTs and a learning guide/performance test after the lecture to evaluate the tools. The test was performed under the e-learning program serviced by C college. This research has presented some encouraging results and raises questions toward future work: how do BGTs impact the feasibility of an online design lecture.

A lot of efforts have been made to develop a new technology for efficient distance education based on a powerful Internet service like World Wide Web. By developed distance education systems, we can study something we want at anytime and anywhere. However in spite of the excellent achievements we have made, something insufficient still is remained. Distance education methods only depending on static homepages or voices and simple drawings may be insufficient to support as much effects as in real class. So it is necessary to develop a new method for teaching students more feasibly and efficiently In this paper, we try to design and implement a lecture authoring system that offers effective distance education with voices, animations, camera images, drawings and etc.. We can expect the designed system can give more efficient education effects like a face-to-face lecture in real class. The enclosed function of intense compression enables to transmit the lectures more speedily. Besides it has caption processing function to serve additional informations to students with caption texts, messages and hyperlinks.

In 2020, the COVID-19 pandemic has brought dramatic changes in the field of engineering education. Contrary to the traditional engineering education emphasis on content-oriented, design-based, hands-on, experimental, and field experience, most of engineering classes in 2020 had to be undertaken remotely online. However, it has not been explored how professors and students perceive about such a shift in engineering education. The aim of the current study was to investigate the perceptions of professors and students on online classes in engineering colleges during spring Semester 2020. Questionnaire data were collected from 100 professors and 4,152 students in the college of engineering. The results of this study were as following: Students were less satisfied with the online classes than professors. The online lecture method that students were most satisfied with was the recorded lecture. This is likely due to the fact that the recorded lectures can be repeated multiple times anytime, anywhere. Moreover, the experimental classes, which conventionally has more of an emphasis on the hands-on experience, also had to be conducted remotely, showing even lower satisfaction among students. Most of professors reported that the average hours they spent on preparing for online lecture increased compared to face-to-face class. Both professors and students preferred in-person exam as a desirable method of end-of-semester assessment for grading. The results of the current study have important implications for the improvement of online course environments. It is important for professors to design a structured class suitable for online education and understand the challenges students encounter during online classes. Also, professors should communicate more openly about their expectations and rubrics for class goals and assignments. Schools also needs to make effort to provide the support for the internet environment of students.

This study investigated recognition of food labeling of high school students (males 94 and females 85) in Yongin region. Recognition of food labeling was very high at 81.6%. For checking food labeling at the time of purchasing, 53.6% of the respondents always checked and the main reason was healthier food choice (49.2%). Satisfaction of food labeling was very low at 18.4%. In spite of very low satisfaction, 70.9% of respondents recognized necessity for education of food labeling. In terms of education method, respondents preferred 'school lecture' the most with 48.6%, which are in the following order: TV/newspaper/journal/book (37.4%) > internet lecture (10.1%) > education from parents (3.9%). Moreover, 83.2% of respondents answered 'positive change (ex. checking food labeling)' after getting education. Consequently, high school students had low level of utilization of food labeling at the time of purchasing. However, they showed high level of perception and educational need of food labeling as well as possibility of positive change after receiving education. Therefore, appropriate school education for food labeling may be able to lead a healthy eating habit of high school students.

Group oriented multicast service is a prerequisite for the current application system for remote lecture and customer service. IP multicast is used to be generally accepted as an internet standard. IP multicast which is designed to support network based replication model can efficiently use host and network resource, however it has some weak points that it has to support IP multicast in the internet by adding multicast-capable internet infrastructure such as router and is vulnerable to security by using public IP address for group identifier. Therefore we propose the trigger based application level multicast model that can enhance both scalability and security by separating the functions, which send and receive message to solve these problems. Our suggested model is expected to ensure the promotion of quality of service and reliability.

Since the inception of the platform business in educational contents, the prominence of the online educational video has flipped the educational environment. Educational contents have been produced on the internet and allowed learners to access more flexible and student-centered. In fact, the number of people watching the educational content online, such as TED talks and YouTube, has increased during the past decade. The ways of delivering the lecture and the course information in online educational videos are totally different from the traditional lectures. In this paper, we aimed to examine and categorize the online educational videos based on the user's engagement and interest in the course contents. For the study, a negative binomial regression analysis was applied to estimate the effects of the attributes of the traditional lectures by comparatively analyzing the educational videos online. Several values are determined as engaging factors in the online educational videos; hybrid production of education and entertainment, shorter duration, and the number of presenters. From the study, we suggests how to produce engaging educational contents which will appeal the attentions from the users. Moreover, the result of the study may use as a guide to the providers making the productive educational videos.

This internet search was made to collect background information for a short-term training proposal for securing a national critical mass in ecological risk assessment the need of which is drastically increasing in every sector of Korean society due to the advent of new environmental regulations in industrialized countries, such as EU REACH. This study depended mainly on internet search engines and individual home pages of concerned universities, colleges, and organizations involved in short-term training. Out of lecture titles and syllabus of 200 Korean universities, 86 Japanese national universities, and numerous English speaking educational and training institutions in the world, 60 syllabi were selected and analysed for comparison purpose. Conclusion from the analysis is as follows: Firstly, individual component lectures for ecological risk assessment is provided at different departments in Korea, but no lecture is at present given under the sole title of ecological risk assessment. Secondly, several lectures under the title of ecological risk assessment are open in English-speaking industrialized countries. Lectures as well as technical training and field studies are emphasized in those courses. Lecturers from the regulatory authorities are also involved in those courses. Several short-term training courses are also under operation. Thirdly, it was concluded that the difference in the level of education/training in ecological risk assessment is originated from the substantive requirement of ecological risk in the concerned laws and regulations. Therefore, it is suggested that training of domestic man power in this area is urgent to cope with the industrial pressure imposed by the environmental regulations concerned with chemicals/articles import and export from/to industrialized countries and also to upgrade the domestic laws and regulations.

The purpose of this study is to analyze the perception of non-face-to-face online undergraduate lectures experienced by foreign learners, to identify problems of online lectures, and to suggest improvements. For this study, the perception of online lectures was investigated and analyzed by foreign undergraduate students who took online lectures at A and B universities. Through this, I explored the design direction, complementary measures, and direction of online lectures to be held at Korean universities in the future. As a result of this study, non-real-time lectures through E campus were recognized as advantages in that they could learn repeatedly and listen to lectures at home., Real-time lectures using Zoom were recognized as an advantage of being able to communicate between professors and learners. Both types of online lectures had many tasks and had difficulty in focusing on the lecture until the end. In the future, it was found that the amount of lecture contents and the amount of tasks should be reduced and the condition and sound quality of the lecture image should be improved. As for the evaluation method, they preferred online evaluation rather than offline evaluation, and they preferred relative evaluation rather than absolute evaluation. The results of this study were able to closely understand how learners perceive online lectures. Also, when conducting online lectures, I was able to know the points that need to be improved in the future. The results of this study are expected to contribute to the design direction of online lectures and the development of online contents at each university.
