광중합 개시제 첨가량의 변화에 따른 Bisphenol A diacrylate UV 경화 film의 역학적 거동
노재호 한국인쇄학회 1994 한국인쇄학회지 Vol.12 No.1
This syudy analyzed the main bodies, marginal space, Position of the main bodies of current textbooks in high schools and "the eriteria of reading system for textbooks" which was suggested the Department of Education and Provided some suggestions for the improvement. The research methods used for the study were both literature review and survey rdsdarch with a questionaire. Inorder to research for the main body of textbook, space of margin, the optimum position of the main body, sizes of litters, spaces between letters, words, lines, length of lines, sizes of main body and margin, and margin and position of main body were checked through a related literature review. For the questionaire experiment, a questionaire based on data drawn from analysis of current textbooks, :criteria for reading system of textbook" suggested by the Department of Education, and some suggestions for improvement by the researcher was made and used for the test, targetting 384 body and girl student in high schools.n high schools.

The signal fading distortion has effect on the capacity of cellular mobile communication systems. The short term fading is solved by signal processing techniques depending on the radio communication methods, but another distortion compensation techniques are necessary to combat long term fading. in this paper, we have simulated the call processing in DS-CDMA system using distributed antennas to overcome the long term fading. From the simulation results, we have conformed that the blocking probability of a new call andthe forced probability of handoff-request-call have decreased by increasing the number of distributed antennas.
CRT 표시장치에서 내삽 추정치에 대한 구간크기의 효과
노재호 江原大學校 産業技術硏究所 1989 産業技術硏究 Vol.9 No.-
This study is concerned with the accuracy, the pattern of error with which subjects can interpolate the location of a pointer or a target between two graduation mrkers with various size on CRT display. Stimuli were graphic images on CRT with a linear, end-marked, ungraduated scales having a traget for t base-line sizes. The location of a target is estimated in units over the range 1-99. Smallest error of estimates was at the near ends and middle of the base-line. The median error was less 2 units, modal error was 1, and most error(;99.6%) was within 10. Subjects had a more tendency to overestimate than to underestimate at the left-part of base-line in all siges, and an opposite tendency at the right-part. A proper size to minimize the interpolation error exists such that size 500. It is suggested that interpolation of fifths and even tenths will give a reguired accuracy for certain situations, and relative location and base-line size has a relevant attribute to interpolate.
