  • Purpose: The present research is a descriptive study aimed at understanding clinical nurses' Video display terminal (VDT) syndrome and identifying the factors that affect their VDT syndrome. Methods: Data were collected from 239 clinical nurses working in two metropolitan cities. Research tools included subject's VDT syndrome assessing musculoskeletal, ophthalmic, dermal, psychiatric, and whole body syndromes. The data were analyzed using frequency analysis, average and standard deviation, t-test, One-way ANOVA, and multiple regression analysis with the SPSS/WIN 20.0 program. Results: The subjects' VDT syndrome score was 1.34 out of 5. There were significant differences in participating subjects' VDT syndrome, hospital's size, working unit, health status, diagnosis of illness, having an Order Communication System (OCS), having an Electronic Medical Record (EMR) System, continuous VDT working for more than one hour, break time during VDT use, VDT use time, comfort of the chair, adjustability of the height of the chair, size of the VDT's desk, distance between the monitor and the user's eyes, resolution of the monitor, and frequency of eye exercise during VDT use. According to the research, influencing factors on VDT syndrome in clinical nurses included size of the VDT's desk, frequency of eye exercise during VDT use, having an EMR system, break time during VDT use, diagnosis illness, and having an OCS' system. Conclusion: The findings from this study can be used as a basis for future VDT syndrome prevention education and programs for clinical nurses.

  • This thesis suggests a methodology of video editing education that is a part of post-production process. The methodology is educating students on contents, theories, technology in phases according to the characteristics of each process. It is based on the training results from the class 'Understanding of Video Contents Production Technology' conducted for high school students between December, 2013 and August, 2014. The result of the satisfaction survey by enrolled students indicated that high educational satisfaction can be obtained by the education methodology.

  • In recent days, research activities on multimedia services mainly focus on the multiplexing system with timing synchromization for media components, such as video, audio and text. The MPEG-4 standard emphasizes object-based coding which includes analysis and understanding of the Image content. Since in MPEG-4 we can define objects and encode them independently, we can manipulate and display each object for different applications. This feature of MPEG-4 is also vero useful for multimedia services, such as video streaming cia different network channels, digital versatile disc, internet TV, video E-mail, and so on. In this Paper, we implement a multimedia streaming system which is compliant with the MPEG-4 system and the MP4 file format.

  • 동영상 콘텐츠는 빠른 인터넷과 동영상을 수요, 공급 할 수 있는 기기가 늘어남에 따라 폭발적으로 성장하고 있다. 이에 맞춰 동영상 콘텐츠에 대한 연구의 중요성은 점점 증가하고 있으며 이러한 연구들을 필요로 하는 소비자들 또한 크게 늘어나고 있다. 그러나 동영상 콘텐츠의 폭발적인 성장과 다르게 동영상의 이해에 관한 연구는 아직까지도 큰 성과 없이 성장을 제대로 하지 못하고 있다. 이 논문에서는 이러한 동영상에 대한 고차원적인 수준의 분석 및 분할 기술을 통해 동영상의 이해를 가능케 하는 모델의 설계와 원리를 소개한다. 또한 이 기술을 활용하여 동영상 콘텐츠의 성장을 활용하는 방법 및 그에 대한 비전을 소개하는 논문이다.

  • This paper proposes a new video-based method of analyzing human gait which is a highly variable dynamic process. It captures a human gait of varying directions as a trajectory in the phase space. The proposed method includes two options of a stochastic process model and a self-organizing feature map as the tool of feature space representation and analysis. Test results show that the model is highly intuitive and we believe it can contribute to our understanding of human activity as well as gait behavior.

  • Ability of understanding students' ideas and thinking is critical to teachers' professional growth. In this study, 'pedagogical reasoning' was conceptualized as teachers' reasoning ability of students' misconceptions and possible causes of misconceptions when they hear and observe students' science discourses. To investigate elementary pre-service teachers' pedagogical reasoning levels, children's science discourses on light reflection and electric circuit were video recorded and 43 pre-service elementary teachers were asked to identify children's misconceptions and possible causes of misconceptions after watching the video clips. In conclusion, pedagogical reasoning levels of pre-service elementary teachers were not high enough, showing significant difference in light reflection and electric circuit. Possible explanations of this difference and educational implications were discussed.

  • In this work, we developed educational contents for ASP programming efficiency. These contents are applied to the cognitive apprentice model, one of the teaching-learning models based in constructivism. Specifically the functions of these contents are as follows: Learners can learn from the lecturing video made of multimedia, they have practical programming training according to the lecturing video showing illustration executed similar to a practical environment, and they grasp level of their understanding by themselves as doing the assigned tasks. Therefore we can anticipate for learning effects, because the contents that we developed can induce learners to learn by themselves and interest them in programming practice.

  • For the applications like video indexing, text understanding, and automatic captions localization system, real-time localization of captions is an essential task. This paper presents a algorithm for localization of captions in MPEG compression images based on I frame. In this algorithm, caption text regions are segmented from background images using their distinguishing texture characteristics and chrominance information. Unlike previously published algorithms which fully decompress the video sequence before extracting the text regions, this algorithm locates candidate caption text region directly in the DCT compressed domain.

  • Understanding actions in videos is an important task. It helps in finding the anomalies present in videos such as fights. Detection of fights becomes more crucial when it comes to sports. This paper focuses on finding fight scenes in Hockey sport videos using blur & radon transform and convolutional neural networks (CNNs). First, the local motion within the video frames has been extracted using blur information. Next, fast fourier and radon transform have been applied on the local motion. The video frames with fight scene have been identified using transfer learning with the help of pre-trained deep learning model VGG-Net. Finally, a comparison of the methodology has been performed using feed forward neural networks. Accuracies of 56.00% and 75.00% have been achieved using feed forward neural network and VGG16-Net, respectively.
