  • As the nonlinear viewing patterns are getting generalized, the needs for VOD service of consumers are increasing in TV, webTV. But today's VOD system is all automated, except the part for posting contents. This study proposes the method for automation of the content posting. For this we analyzed the broadcast program structures by genre in order to detect the transition point between the advertisement and the contents. It was found that regular black frames were set in the transition during fade in and out. We propose an efficient approach to automatically detect the black frames using RGB values of each frame that enable VOD content posting and replace an advertisement in VOD service.

  • Lately, Digital Photogrammetry has been increasingly applied to various hightech industries and becomes one of more interesting focuses of study than ever. Thus, this study aims to develop a Road Horizontal Alignment Information System by means of digital photogrammetry. Data acquired from digital photographic techniques were processed using Delphi, an object oriented programming language to develop a computer aided program, that allows us to build the information on Road Horizontal Alignment(Beginning Point of Curve, Ending Point of Curve, Radius, Intersection Point). The developed program could maximize visualization for better analysis compared with traditional programs because it utilizes many image data. Comparing with data from traditional horizontal alignment extraction programs based on the principle of least square method, the data acquired by Horizontal Alignment Information and kinematic GPS showed out of the developed road information systems the improved accuracy of IP value up to about 2m in the direction of X, Y axes, where the accuracy of curve radius(R) becomes enhanced up to about 2.5 m.

  • In this study, the problem of discontinuous contact in two functionally graded (FG) layers resting on a rigid plane and loaded by two rigid blocks is solved by the finite element method (FEM). Separate analyzes are made for the cases where the top surfaces of the problem layers are metal, the bottom surfaces are ceramic and the top surfaces are ceramic and the bottom surfaces are metal. For the problem, it is accepted that all surfaces are frictionless. A two-dimensional FEM analysis of the problem is made by using a special macro added to the ANSYS package program The solution of this study, which has no analytical solution in the literature, is given with FEM. Analyzes are made by loading different Q and P loads on the blocks. The normal stress (σy) distributions at the interfaces of FG layers and between the substrate and the rigid plane interface are obtained. In addition, the starting and ending points of the separations between these surfaces are determined. The normal stresses (σx, σy) and shear stresses (τxy) at the point of separation are obtained along the depth. The results obtained are shown in graphics and tables. With this method, effective results are obtained in a very short time. In addition, analytically complex and long problems can be solved with this method.

  • This study was aimed to identify the effect of abdominal moxibustion on premenstrual syndrome and dysmenorrhea in university students. The data were collected by using questionnaires from April 25, 2005 to June 20, 2005. The subjects were university students from in the Pusan metropolitan area who had complained of menstrual discomfort. Thirteen students were assigned to the experimental group and fourteen students to the control group. The research design of this study was a nonequivalent control group pretest-posttest design. In the research method pretest were conducted through measurement based on scores of general character, menstrual character, premenstrual syndrome and dysmenorrhea in the experimental group and the control group. Experimentation was conducted by abdominal moxibustion being applied on the kwan-won hole and Ki-hae hole for 25 minutes at a time, three times a week, form the ending of one menstrual cycle to the beginning of the next menstrual cycle were in the experimental group. After treatment was finished, post tests conducted through measurement based on scores of premenstrual syndrome and dysmenorrhea in the experimental group. The control group conducted a point of same time and same measurement with the experimental group. The instruments used in this study MDQ(Menstual Distress Questionnaire) developed by moos(1968) and the VAS(Visual Analogue Scale) developed by Cline(1992). The data were analysed by SPSS/ win 12.0 program with ${\chi}$2-test and t-test to verify identification among subjects' general characteristics and menstrual characteristics. Hypothesis verification was analysed with t-test. The results of the study are as follows: The hypothesis, 'the experimental group who received abdominal moxibustion will decrease premenstrual symptoms more than the control group', was supported (t= -2.121, p=.022). The hypothesis, 'the experimental group who received adbominal moxibustion will decrease dysmenorrhea compared to the control group', was supported (t=-4.424, p=.001). As a result of this study, abdominal moxibustion will be used as a nursing aide to improve and prevent menstrual discomfort of university students who have premenstrual syndrome and dysmenorrhea.
