다수의 색상 및 거리 정보로 구성된 몰입형 영상 부호화를 위한 MPEG immersive video (MIV) 표준은 각 시점의 영상 간 중복성 제거 및 잔여 영상 병합을 통한 압축률 향상을 목표로 한다. 시점에 따른 카메라 그룹핑을 통해 압축률 향상이 가능하나, 그룹 기반 MIV 부호화 기술은 최근 활발히 논의되고 있지 않다. 따라서 본 논문은 최신 버전의 MIV 참조 소프트웨어에 그룹 기반 부호화 기술을 이식하고 적응적 스트리밍을 위한 그룹 기반 부호화 기술의 효율을 검증하였다.

This study seeks to prove three points through the research. The first point is to examine the changes of international attitudes with actual experiences using synchronous international distance learning. The second point is to examine the effectiveness of a synchronous international distance system. And the final point is to compare international attitudes among middle school and undergraduate school students in Korea and Japan. The study used the DVTS for audio and video communication tools and automatic translating chat as a text communication tool. This combination of communication tools was very effective for students from both countries to communicate for international collaborative learning activities. The study found several interesting patterns of attitude change from the results of the study. For whole category analysis, there are positive changes in four categories of international attitudes: consciousness to foreign countries, consideration for other's viewpoints, motivation for international education, and recognition for the counterpart country. However, there was no change in the nationality category.

Purpose: This study was conducted to investigate the effects of core basic nursing education using cellular phone video recordings on self-confidence in performance, achievement, and practice satisfaction. Methods: The research design was a nonequivalent control group modified and non-synchronized design. The participants were assigned to either the experimental (n=60) or control group (n=67). During one semester, the experimental group received training for 10 selected core basic nursing skills using cellular phone video recording. The control group, also for one semester, received training with traditional practices. Self-confidence in performance and practice satisfaction were measured using a questionnaire, and achievement was evaluated by professors at the conclusion of the semester. Collected data were analyzed using t-test and Pearson correlation coefficients. Results: Self-confidence in performance increased significantly after training in the experimental group (t=7.94, p<.001). The experimental group showed significantly higher self-confidence in performance (t=2.39, p=.018) and achievement (t=2.40, p=.018) compared to the control group. However, the difference in practice satisfaction was not statistically significant. Conclusion: The results indicate that cellular phone video recording is effective in improving self-confidence in performance and achievement of core basic nursing skills.

The purpose of this study was to investigate the relationship between the quantitative analysis of biomechanical movement and the qualitative analysis of video software in order to evaluate for the walking movement. The fourteen collegiate students who agreed with the purpose and method of this study participated as subjects. The slow walking and fast walking of the subjects in the place of experiment were photographed, and calculated several mechanical factors. This empirical evidence from the experiment indicated the significant difference(p<.001) between each distant factors of the walking movement for both analyses methods, but there was no statistically significant difference between the spacial factors observed in the experiment. For more detail, no significant difference between the walking ratios that expressed the coordination between stride length and stride frequency was found. The findings also indicated the high coefficient of correlation(over r=.9) which supports higher explanation force for the biomechanical method and the Dartfish video software method. Therefore, if the data was gathered by using the proper experimental method, the video software method could be used just like the quantitative data of biomechanical method.

In or automotive engineering education is introduced. Main objective of the system is teaching disassemble/assemble procedure of automatic transmission of a vehicle to students, who study automotive engineering. System includes vehicle transmission, set of tools and mechanical facilities, two video cameras, computer with developed software, HMD glasses and two LCD screens. Developed software gives instructions on assembling and disassembling processes of real vehicle transmission with the help of augmenting virtual reality objects on the video stream. Overlaying of 3D instructions on the technological workspace can be used as an interactive educational material. In disassembling process, mechanical parts which should be disassembled are augmented on video stream from video cameras. Same is done for assembling process. Animation and other visual effects are applied for better indication of the current assembling/disassembling instruction. During learning and training, student can see what parts of vehicle transmission and in which order should be assembled or disassembled. Required tools and technological operations are displayed to a student with the help of augmented reality, as well. As a result, the system guides a student step-by-step through an assembly/disassembly sequence. During educational process a student has an opportunity to return back to any previous instruction if it is necessary. Developed augmented reality system makes educational process more interesting and intuitive. Using of augmented reality system for engineering education in automotive technology makes learning process easier and financially more effective.

This study was conducted with a non-equivalent control group experimental design to investigate the effects of a video-based infection control program through the application of the social cognitive theory on caregivers. Forty-six caregivers were recruited, with 23 pairs being randomly assigned to the control and experimental groups each. While the experimental group took part in the video-based education, the control group was involved in typical lectures. For two weeks, both groups were educated on the principles of infection control, medical and external handwashing, standard precautions, and quarantine. Their knowledge, performance, and self-efficacy were evaluated before and after the program. There was a significant increase in knowledge (p<.001 and p=.005) and infection control performance (p<.001) in the experimental and control groups. Similarly, self-efficacy, self-regulatory efficacy, task-difficulty preference and confidence significantly increased in the experimental group (p<.001). In the control group, only task-difficulty preference significantly increased (p=.005). Consequently, the online video-based infection control education program applying the social cognitive theory proved effective in improving the caregivers' knowledge and performance in infection control, and their self-efficacy. We suggest the use of this program in effective infection control education for caregivers in the future.

The aim of this study to provide basic reference data for the development of video contents used in pattern drafting education and to explore the possibility of utilizing YouTube videos in such education. Subject videos were selected using the number of views. A total of 596 videos and 28 channels were analyzed for the period July to September 2019 and the results are as follows. With regard to content, there were 27 pattern drafting items, the majority being dress, pants, skirt, blouse and sleeve drafting, although high-level content such as cowl, bustier, corset patterns were also available. Therefore, there is a high likelihood that YouTube videos could be used as educational material, especially as supplementary references to provide specific examples and easy explanations for difficult concepts or method, for students majoring in this field. However, as most videos currently focus on a few items, expanding video content to features a wider variety of clothing items at different levels is necessary. With regard to video length, it mostly ranged from 10 to 15 minutes. It is not advisable to create lengthy lecture-style videos expounding on different principles or variations in pattern drafting when developing educational video material.

디지털 비디오 압축과 인터넷 기술의 발전으로 비디오에 대한 수요가 폭발적으로 늘어나고 있으며, 사용자 제작 콘텐트(UCC)도 대량으로 생산되고 있다. 따라서, 디지털 비디오 라이브러리 구축과 검색에 대한 기술 연구가 어느 때보다 시급하게 요구되고 있다. 그러나 사용자가 전체 비디오의 일부 내용을 의미기반으로 검색해서 보고 싶은 욕망을 충족시켜주기는 매우 어려운 상황이다. 본고에서는 디지털 비디오를 의미 검색하기 위하여 장면을 뽑아내고, 내용을 분석하는 방법을 제안하고, 5개의 스포츠(축구, 야구, 골프, 농구, 배구) 뉴스 비디오를 자동 분류한 실험 결과를 소개하였다.
