郭義鍾,尹厚炳,鄭成鍾 全北大學校 1994 論文集 Vol.37 No.-

As the diverse of industry increase information to handle, requirement of automatic input system has been increased. And these automatic input systems have been developed as the font of various kinds of recognition system. Expecially. drawing recognition system which is an automatic input system of drawing has been studied since 1970. But most of those systems are on-line system. On-line system can not continously display a status of making drawing by restriction of size of monitor, And can not input a printed data or hand drawn data with keyboard. In this paper, an off-line system to beautify the input data coming through scanner is proposed, and input data is a hand drawn data or printed data consisting of texts and graphics. To do this process, input data will be separated into line component, loop component, text. As shown in results, hand drawns or printed datas are separated into charater, line, and loop component. And also these separated component are beautified through symbol recognition.

In this paper, fundamental properties of cement mortar using recycled water with stabilizing agent are discussed in order to investigate the applicability of recycled water. Stabilizing agent content, solid contents and open time are varied in this paper. For fresh mortar properties, highest fluidity with 0.15% of stabilizing agent was observed and air content was increased with an increase in stabilizing agent contents. Solid contents and open time of recycled water had nothing to do with fluidity and air content loss. Little difference in setting time was found with the presence of stabilizing agent and without, while it was accelerated with an increase in open time and solid content. For strength properties, the highest strength value was observed at 0.15% of stabilizing agent. An increase in solid contents resulted in an enhancement of strength, while strength decreased with an increase in open time and elapse of age. Drying shrinkage exhibited a reduction with an increase in stabilizing agent contents and open time. From the present paper, the combination of 0.15% of sacharic based stabilizing agent, 3% of solid content and 1day of open time is found to be an optimal condition to perform effectively.

압저항형 스마트 실리콘 압력 센서를 0.6 ㎛ 이중 폴리 실리콘 이중 금속 CMOS 공정으로 구현하기 위하여 설계하였다. 이 스마트 실리콘 압력 센서는 압저항형 저항기들로 된 휘스톤 브리지를 갖는 다이아프램과 op-amp, A/D 변환기, 및 UART 회로 등의 주변회로 들로 구성되어 있다. 브리지 회로의 출력 전압과 압력에 의한 기계적 응력 사이의 관계를 COSMOS-M 상용프로그램으로 다이아프램의 응력 분포를 모의실험하여, 압저항기의 최적의 위치와 크기에 대한 연구를 하였다. CMOS op-amp 회로는 규정된 출력 특성을 얻기 위하여 크기가 다른 트랜지스터들로 설계하여 HSPICE로 모의실험하여 최적화 시켰다. A/D 변화기 회로는 가능한 칩 면적을 줄이기 위하여 서브 레인징 기법과 신경 MOSFET 구조를 이용하여 설계하였다. UART회로는 VHDL 소스 코드와 셀 라이브러리를 이용하고 Synopsys로 합성하여 설계하였다. 회로의 물리적 레이아우트 설계는 Mentor 틀로 설계하였다. 그러나 온도보상회로와 출력오프셋 문제는 아직 해결하지 못하고 다음에 연구할 예정이다. A piezoresistive smart silicon pressure sensor is designed to implement with 0.6 ㎛ double-polysilicon double-metal CMOS precess. This smart pressure sensor is composed of a diaphragm with piezoresistive resistors' Wheatstone bridge and the peripheral circuitry of op-amp, A/D converter and UART. The relationship between the output voltage of the bridge circuit and the mechanical stress by applied pressure was studied by simulating the stress distribution on the diaphragm with COSMOS-M package program to optimize the size and position of piezoresistors. The CMOS op-amp circuit was designed with different CMOS transistor sizes to obtain the defined op-amp output characteristics and simulated with HSPICE. The A/D converter was designed using neuron MOSFET structure and sub-ranging method to minimize the chip area. The UART circuit was designed by using VHDL source code and cell library and by synthesizing with Synopses and the physical layout of the circuit was designed with Mentor tools. The problems for temperature compensation and the output voltage offset were not yet considered.

Cellular transforming genes have been identified in a number of different tumor cell lines and tumor types. A significant number of these oncogenes belong to the ras gene family. The ras gene family consists of three closely related genes:H-ras, K-ras and N-ras which code for a related 21 kDa protein. Mutations in codon 12, 13 and 61 of one of the three ras genes convert these genes into acute oncogenes. The presence of H-ras gene mutations has important prognostic implications in various tumors. Each genomic DNA was isolated from tumors induced by implantation with DMBA, or by treatment with DMBA-implantation/irradiation. When genome DNA was transfected into NIH 3T3 cells and investigated by two-step PCR-RFLP, the following results were concluded: 1. Transformation foci developed in two groups then the genome DNA of two experimental groups were transfected into NIH 3T3 cells. 2. Transformation efficiency was 0.01-0.02 foci/㎍DNA in the experimental group with the DMBA-implantation/irradiation according to results of transfection assay. 3. When the point mutation of H-ras gene was investigated by a two-step PCR-RFLP, there was 13.9%(5/36) in the experimental group with the DMBA implantation, 15.4%(6/39) in the expermetal group with the DMBA-implantation/irradiation. 4. The point mutation in codon 12 and 61 of H-ras was 5.6%(2/36) and 8.3%(3/36) in the experimental group with the DMBA implantation. 5. The point mutation in codon 12 and 61 of H-ras gene was 7.7%(3/39) in the experimental group with the DMBA-implantation/irradiation.

The objective of present paper is to investigate the engineering properties of concrete using recycling water incorporating saccharic based stabilizing agent in order to improve qualities of concrete in the region of normal strength and high strength. According to test results, fluidity and air content do not exhibit significant difference with an increase in stabilizing agent contents. Bleeding was not observed at 30% of W Ie, regardless of stabilizing agent contents, nonetheless, concrete with stabilizing agent of 0.15% was observed to occur the least bleeding at 40 and 50% of W IC. For setting time, although presence of recycled water accelerates setting time, setting time shows to be retarded gradually with an increase in stabilizing agent content. For compressive strength, use of stabilizing agent enhanced compressive strength of concrete compared with that of concrete without stabilizing agent. In the side of strength enhancement, adequate dosage of stabilizing agent is found to be 0.15%. As dosage of stabilizing agent increased above 0.15%, drying shrinkage exhibited a tendency to decrease.
