Background : This study was identified the effects of a video CD Rehabilitation program on the range of knee angle and activities of daily living in patients with a total knee replacement Method : The data was collected from March 1 to May 31 2009 for the control group and from July 1 to September 31 2009 for the experimental group. The control and experimental groups contained 19 subjects each. A video CD Rehabilitation program configured to 8 minutes in length was shown 8 times every other day. Result : 1. On the day of Hemovac removal, the knee angle and CPM angle in the experimental group increased significantly, but they remained relatively constant on post operation day 21. 2. The activities of daily living were significantly different in the experimental group. Conclusion : 1. On the day of Hemovac removal, the knee angle and CPM angle in the experimental group increased significantly, but they remained relatively constant on post operation day 21. 2. The activities of daily living were significantly different in the experimental group.

Computer programs are required from all areas in society including machine, space, aviation, and medicine. However, the programming curriculum is getting hard despite a lot of teaching materials and video lessons. Programming languages are very diverse, but most of them use the same structure, and they only have different expression methods. Therefore, if one learns one programming language, then it doesn't need to spend a lot of time and efforts to learn another programming langue. Most programming languages use the structure of sequence, selection, and repletion in general. The important thing for programming learners is the structure or algorithm of programming not the grammar of program. This study designed and implemented the language learning system to learn structured programming by using a flowchart.

There have been many trials for development of games using augmented reality. This paper presents a 2D puzzle game system using HSV color space to detect hand posture from an input image by smart device's cameras in real time. The developed game in this paper brings smart devices and the computer vision closer. Also this game can be a new interactive technology utilizing both the mobility of smart devices and the tangible interactivity of virtual reality in education and entertainment environments.

Purpose: The purpose of this study was to identify the effects of CD-ROM education on anxiety and self-care compliance in patients undergoing spinal surgery. Method: This study used a nonequivalent control time difference design. A sample of 51 participants received both CD-ROM education (n=25) or booklet education (n=26) regarding spinal surgery procedure and postoperative self-care. The data were collected using a self-administered questionnaire containing State-Trait Anxiety Inventory (STAI Form Y-2), Visual analog scale, and self-care compliance. Result: The level of trait anxiety in the experimental group was not significantly different from that in the control group (t=-6.44, p=.523). The level of state anxiety in the experimental group was significantly lower than in that the control group according to time changes (F=4.17, p=.018). State anxiety showed significantly negative correlation to self-care compliance (r=-.30, p=.034). Conclusion: The education program using CD-ROM for spinal surgery patients can be applied to nursing practice for relieving state anxiety and promoting self-care compliance.

Purpose: The aim of this study was to identify the effect of video programs of cardiopulmonary cerebral resuscitation (CPCR) education of cardiopulmonary cerebral resuscitation of nurses. Methods: The subjects of the study were 64 nurses working in a university hospital. Nurse's CPCR performance have been measured four times (pre-test, post-test at immediately, 3 months and 6 months after intervention). Data were collected from February to August 2013. Results: There were significant differences in knowledge, attitude, self-efficacy, and performance between groups by measure time. And there were significant interactions in knowledge, self-efficacy, and performance between groups, within groups, except for the attitude. The video programs of CPCR interventions appear to be effective in the improvement of knowledge, self-efficacy, and performance, as compared to the control group. Conclusion: The video programs of CPCR education was an effective intervention to improve and retain the level of knowledge, attitude, self-efficacy and performance. And the video program of CPCR education have an advantage of self-learning effect for nurses with shift work. Therefore video programs of CPCR education will be utilized for continuing nurse's education.

The purpose of this study is (a)to identify reading effect on the imagination, and (b)to compare reading effect with audio-visual materials. For these purposes, 25 elementary school students and 11 university students participated in the reading project. The participants of this project painted a car and a beast after reading a book and watching a movie, Main findings and conclusions made in this study are summarised as follows : (1)Reading is better than a movie for the people's imagination. (2)Children can imagine much more freely than the adults. It is expected that these results can be used for the children's reading education and programs.

Digital literacy is an important factor in the discourses on the knowledge sharing on the campus. This article analyzed the impact of digital literacy of knowledge-sharing capabilities in the university. As a result, digital literacy was found to significantly affect student knowledge-sharing capabilities in the university studied. Results show that video and animation literacy is the most influential factor and image literacy is the second-most influential factor for student knowledge-sharing. Those results can be used as a framework for developing digital literacy program.

Recently, as the demand for the mobile platform market in the virtual/augmented/mixed reality field is increasing, experiential content that gives users a real-world felt through a virtual environment is drawing attention. In this paper, as a method of tracking a tracker for user location estimation in a virtual space movement platform for motion capture of trainees, we present a method of estimating 3D coordinates of the 3D cross covariance through the coordinates of the markers projected on the image. In addition, the validity of the proposed algorithm is verified through rigid body tracking experiments.
