Zipper CMOS PLA 의 설계 및 테스트

이건기,한석붕,이문수 慶尙大學校生産技術硏究所 1988 生産技術硏究所論文集 Vol.4 No.-

In this paper, a new circuit type, the Zipper CMOS PLA, is described. Then a testable design and testing method for it will be discussed. The Zipper CMOS PLA has the regular structure of PLA and a NAND-NAND logic Zipper CMOS circuit. Therefore it incorporates all the advantages of dynamic CMOS circuit and array logic. In the testable design, feedback loops are formed in Zipper CMOS PLA by adding simple extra circuits. The oscillation, in test mode, occurs through the loops and can be observed at the outputs. By the proposed method, test application and evaluation are easy. The fault coverage is improved. The algorithms are also proposed, which add the extra circuits to the Zipper CMOS PLA and generate the test patterns. The validity of the designs is verified by performing the logic level simulation. Also the proposed algortithms are realized on VAX 11/750(UNIX) in C language.

First of all, the writing juding from background and reason is obviously a matter of the national consciousness on the study of Korean morden history of physical education. I indicates a national consciousness as to whether the subject of a thesis for a doctorate or master on the study of Korean morden history of physical education, have classified 6 step with limit and problem. Finally, when I think on study of Korean morden history of physical education, I indicate three types of theory about study object and project it. To the better a scientific study of Korean morden history of physical education, the result has been a concept of national consciousness with a point of study and attitude as usual, and I hope that a method of study will help both interest in and debate over the issues to continue.

소아의 치아우식증을 예방하기 위한 불소의 국소도포는 소아치과 영역에서 널리 시행되고 있다. 하지만 이러한 잇점에도 불구하고 최근 수복물 표면을 거칠게 한다는 부작용에 대해 논란이 되고 있다. 이에 본 연구에서는 불소도포가 심미 수복물의 표면변화에 미치는 영향을 평가하기 위해 수종의 복합레진에 국소도포용 불소젤을 도포시킨 후 변화를 관찰하였다. 시판용 레진인 Z 250(3M ESPE, USA), Ultraseal XT^(®)(Ultradent, USA), Filtek flow^(®)(3M, USA) , Revolution^(®)(Kerr, USA), Denfil^(®)(Vericom,Korea)를 이용하여 시편을 제작하고, 불소젤은 Topex^(®)(Sultan Dental Products,Canada)을 각각 1분과 4분동안 도포시켰다. 각 제품마다 불소젤을 도포하지 않은 5개의 시편을 대조군으로 사용하였다. 그 후 이 시편들의 표면 거칠기(Ra value,㎛)와 무게 차이를 측정하고 주사전자현미경을 이용하여 다음과 같은 결과를 얻었다. 1. 불소젤을 도포시키지 않은 대조군에서 가장 평활한 표면을 보였으며 1분군, 4분군 순으로 표면 거칠기가 증가하였다. 그리고 Revolution을 제외한 모든 제품에서 유의한 차이를 보였다(p<0.05). 2. 국소도포용 불소젤을 도포한 각 레진 시편의 무게 차이를 비교한 결과 대조군, 1분군, 4분군 간에 유의한 차이는 없었다(p>0.05). 3. 주사전자현미경 관찰시 불소젤에 도포시킨 실험군은 대조군에 비해 거친 표면을 나타냈다. 이상의 결과로 국소적 불소도포는 복합레진의 표면 거칠기에 영향을 미치며 이를 고려하여 사용한다면 4분보다는 1분간의 불소도포법을 이용하는 것을 추천할 수 있을 것으로 사료된다. Topical fluoride application for children is a widely performed procedure in the field of pediatric dentistry to prevent dental caries. However, it is recently recognized as having some unwanted effects on several esthetic restorative materials as it roughens the surface of the restorative materials. The aim of this study was to evaluate the surface changes in composite resins to topical fluoride. Composite resins(Z 250^(®),Ultraseal XT^(®),Filtek flow^(®),Revolution^(®),Denfil^(®))in topical fluoride agents were immersed and their surface roughness, weight loss and SEM were evaluated. The results were as follows: 1. The 4 minutes-immersion groups showed more roughened surface than 1 minute-immersion groups and the control groups showed the smoothest surface among all the materials, and there was statistically significant difference except the revolution between the groups. 2. There was no significant difference between the 1 minute-immersion groups and 4 minutes-immersion groups in weight loss. 3. The experimental group treated with topical fluoride gel showed the generally mere roughened surface than control group in the SEM findings.

2단 평행구조 로보트 프로그램 개발

박근우,이민기 國立 昌原大學校 産業技術硏究所 1996 産技硏論文集 Vol.10 No.-

This paper introduces the development of program for the double parallel robot which is applied to a machining work. The robot system consists of a robot, PC (personal computer), DMC (DSP Motion Controller), and machining tools. We analyze the motions of robot by an inverse kinematics +and drive the motions by DC Servo motors. In order to actuate the motor, we use the motion functions of the DMC, which is implemented in "C" language. Without adding a teaching box, we teach the robot with keyboard itself. Furthermore, we develope a 3-D graphics simulator to investigate the feasibility for application program in off-line.

心電圖 信號의 雜音 除去와 R-점 檢出을 爲한 웨이브렛 解析의 適用

One of the main techniques for diagnosing heart disease is by examining the electrocardiogram(ECG). Many studies on detecting the QRS complex, P, and T waves have been performed because meaningful information is contained in these parameters. However, the earlier detecting techniques can not effectively extract those parameters from the ECG that is severely contaminated by noise source such as 60Hz power-line interference, muscle artifact and baseline drift. In this paper, we performed the extracting of parameters from the ECG signal and recovering using wavelet transform that recently been applying to various fields.

유전체 연구를 위한 Well-plate 자동 교환 시스템의 개발

나건영,김기대,이현동,이영규,김찬수 충남대학교 농업과학연구소 2004 농업과학연구 Vol.31 No.1

In this study, the automatic system exchanging well-plates was developed as a basic stage of the genome project. The developed system consisted of the plate fixing well-plates, the well-plate cassette, the head to move a well-plate from the well-plate cassette to the plate fixing well-plates before genome work or from the plate to the cassette after the work, the manipulator to move the head on the X, Y and Z axes and the control system. The performance test to exchange well-plates with the robotic system developed was carried out. The time to set an well-plate from the weD-plate cassette onto the board fixing well-plates was 55 seconds and the time for 9 ones was 8 minutes and 15 seconds. It took 57 seconds to move a well-plate from the board to the cassette and 8 minutes and 33 seconds for 9 ones.

The purpose of this study was to investigate the relationships among trunk muscle, knee, and ankle strengths using Cybex770, the isokinetic muscle functioning measurement device. 41 K and Y University soccer players who did not have any experience about back pain or spine surgery were recruited as subjects. The results of the study were as follows. 1. Trunk extension was significantly higher than trunk flexion and muscle strength was diminished with increasing load speed. 2. Trunk flexion/extension ratio was well balanced at 30。/sec but this balance was broken with increasing load speed. 3. At 60。/sec of load speed, the knee extension and flexion of the left side were higher than those of the right side. 4. At 60。/sec of load speed, the ipsilateral muscle strengths of the left knee were well balanced but those of the right side were imbalanced. 5. At 60。/sec of load spped, the ratio of bilateral muscle strength of knee was -18.5±32.3% and this implies the possibility of knee injury. 6. Plantalflexion and dorsiflexion of the right ankle were higher than those of the left side, and dorsiflexion/plantalflexion ratio of the left side was higher than that of the right side. 7. The ratio of bilateral muscle strength of ankle at 60。/sec of load speed represented a balanced muscle development but this balance was broken with increasing load speed.8. There were partially significant relationships between trunk muscle and knee strengths. and between knee and ankle strengths. In conclusion, the trunk muscle strength of soccer player might be a very important factor to improve performance. In addition. a training technique which considering strength and speed is needed to develop not static but dynamic strength. This training not only develops well balanced muscle strength but also protects sport injury. Thus, the isokinetic training of trunk could improve the trunk muscle strength. and increase the ability of flexion/extension of knee and ankle.
