Since the first HDV(High Definition Video) camcoder, HDR-FX1 with 1080i resolution, had been launched at 2004, the image capture and record with HD resolution have been possible by the various types of camcoder and recorder which can support the HDV format. At a present day, a non-linear editing system, which is composed of only one computer, can capture, edit and export the image with HDV format. The HDV format has the same class of resolution with HD and the same data transfer bit rate of DV(Digital Video). Additionally, the image with HDV format can be recorded in 6mm DV cassette tape. It is possible because the HDV format uses the concept of Long GOP(Gorup of pictures) method for its compression. In this paper, the characteristic feature of HDV format, the essential factors in editing with HDV format and the concept of Long GOP method for its compression have been studied for the way of effective HDV editing.

Purpose: Our research team developed two types of hepatitis B prevention materials: video tape and leaflet. We showed them to two groups of subjects separately, and the effect of education was compared to find out a more effective educational material for preventing hepatitis B. Method: Students at a middle school and a high school, one class for each school year, participated in the five areas of this study. They were educated for hepatitis management using the video tape and the leaflet. Before and after the education, they were tested for knowledge on hepatitis and health belief to analyze the effect of education. Results: 1) The video tape was more effective than the leaflet in delivering hepatitis knowledge and enhancing sensitivity & severity in health belief. 2) Hepatitis knowledge was improved significantly after the education. 3) Sensitivity & severity in health belief was improved significantly after the education. 4) Benefit in health belief was improved significantly after the education. 5) Barrier in health belief decreased significantly after the education. 6) There was a correlation between hepatitis knowledge, sensitivity & severity in health belief and benefit in health belief. Conclusion: We suggest that for preventing hepatitis B it would be helpful to educate students in middle school and high school face to face with educational materials.

Present, we cannot expect the maximum studying effect in a home economics and the drill unit of secondary schools because of several problems. Such problems can be enumerated as follows. 1. The explaination of a making process in texts would be difficult for the students who have a poor understanding to grasp. 2. The much effort would be made due to teacher’s repeated exhibition, by which the progress of a text might be unreasonable. 3. The teachers unaccustomed to the drill might treat it carelessly and become to avoid it. 4. The skill to grasp a general work flow might be lack. Baseing on such problems, this researcher did using a medium of Video in teaching method of home economics. For this purpose, the quality of Video Tape would be important. Above all, we made out the script of Video Tape through advices of specialists in Video medium, majors in home economics, and the students teaching of home economics and the concerned persons, by which we recorded a gather skirt, as a finished goods, especially of the characteristics of each kind of a skirt. Next, we recorded and produced the total steps from a preparation of skirt-making to a finishing as using a V.T.R. shot technique. The Video would be screened and the supplemented explaination of a teacher would be added in a step of instruction. In the development of instruction, students would begin the making. The expected effects according to using Video Tape are as follows. 1. The making order of text would be exhibited by a model directly and the explaination of a narrator would be added concurrently, by which students would understand it easily as confirming each step. 2. All students can watch these steps owing to a close up, one of the V.T.R Techniques. Accordingly, the teacher’s efforts would be decreased and the proper progress of a text could be maintained because of no repeated exhibition of a teacher. 3. To the teachers unaccustomed to and interested in a drill, the medium would become a subsidiary means. 4. Study all steps of a making, students would become to understand the general flow of a work. Therefore, it might be possible to generalize another units of a making. However though this study was designed don a basis of such effects, the using effects based on only the existing study results, and was focused on the production of a medium. Because this research would be a teacher and there was noncooperation of secondary schools, it was impossible to experiment in schools, which was the prime limitation of this study. Therefore we should be experiment further for the continuous studying.

In one VTR(Video Tape Recorder), two or more heads are used to record or reproduce video signals. To obtain a uniform quality of a VTR, video heads should have similar charcteristics such as geometrical shapes and electro-magnetic performances. This research is aimed to develop a visual inspection system that can measure four geoemtrical parameters;HO, HI, Tw and Cw. To obtain a high realable results, DSP based image board and target based image processing algorithms were used. A series of experiments was performed for one thousands of video heads. From observation of the experimental results, the system is found to show good performance for inspection of video heads.

In Korea the vehicle enforcement system(VES) detects speeding vehicle using two inductive loop detectors. And the speed reliability of theirs are evaluated through the analysis of image frame which is captured from video camera. This method is validated to evaluate VES on Korea Laboratory Accreditation Scheme(KOLAS) but it needs much time and expense for the analysis of image frame. Because the number of VES are increasing rapidly, the requirement of new evaluation method is necessary. On this paper, the tape switch sensor as a substitution of existing method was introduced and its application on the site are discussed. On the site test we compared the tape switch sensor on the speed measurement of vehicle with the video image frame. As a result we have founded that the tape switch sensor is evaluated to be feasible system on site in respect to measure the overspeed vehicle.

Periodic longitudinal vibrations of a video and audio tape and the like used for transducing pictures and sounds may be induced by self-excited vibrations which are caused by frictions against the heads and guides, and their eccentricity, noncircularity or irregularity. It is important to analyze the longitudinal vibration of a tape because it causes distortions of a reproduced signal. It is difficult to measure directly the longitudinal vibration. In this paper a method estimating longitudinal vibration using impulse responses in the transverse direction is presented. And, the parameters boundary domain where the transverse and longitudinal vibration can be decoupled is introduced. In the domain where the both vibrations are decoupled, analytic methods using frequency characteristics and transient responses of the transverse vibration, respectively, are presented. The time domain method predicted more exactly the instantaneous phase of the longitudinal vibration than frequency domain method did.
