A control program of an engine control module (ECM) was developed, and its control performance was verified on a 750Ps marine diesel engine. The control method was designed for an engine rotational speed control system. For ECM hardware, the commercial rapid control prototype (RCP) ECM was used. The programming tool for control algorithm development was the MatLab/Simulink. The main control algorithm assembled many control models as engine cranking, run, and stall. Each model has sub-models to input/output control signals. The target engine speed was input signal from a speed control lever, and control output signal of the ECM was sent to the unit-injectors for fuel injection. The engine test was performed under various conditions of engine rotational speeds and dynamometer loads. The test results show that the control function of the ECM is suitable for electrical marine diesel engines.

로봇의 기능이 다양해지며 복잡해지고 있다. 주위의 환경을 감지하는 센서로는 거리정보 뿐만 아니라 영상 정보, 음성 정보까지 이용하고 있다. 본 논문에서는 다양한 입력정보를 가진 로봇을 제어하기 위한 알고리즘으로 2-layer fuzzy control을 제안한다. 장애물 회피의 경우에 다수의 거리 센서를 이용하는데 이것을 앞쪽, 왼쪽, 오른쪽으로 분류하여 3개의 sub-controller를 가지고 퍼지 추론을 한 다음, 2단계에서는 이 3개의 sub-controller의 출력으로 조합된 퍼지 추론을 하여 통합적인 제어를 한다. 본문에서는 2-layer fuzzy controller와 비슷한 구조를 갖는 hierarchical fuzzy controller와 비교를 하였으며 robot following에도 적용하여 각각에 대한 시뮬레이션과 실험을 통해 성능을 확인한다. The ability of robot is being various and complex. The robot is utilizing distance, image data and voice data for sensing its circumstance. This paper suggests the 2-layer fuzzy control as the algorithm that control robot with various sensor information. In a obstacle avoidance, it utilizes many range finders and classifies them into 3parts(front, left, right). In 3 sub-controllers, the controller executes fuzzy conference. And then it executes combined control with a combination of outputs of 3 sub-controllers in the second step. The text compares the 2-layer fuzzy controller with the hierarchical fuzzy controller that has analogous structure. And the performance of the 2-layer fuzzy controller is confirmed by application this controller to robot following, simulation to each other and real experiment.

조현호,윤광섭,Cho, Hyun-Ho,Yoon, Kwang-Sub 대한전자공학회 2005 電子工學會論文誌-TC (Telecommunications) Vol.42 No.11

본 논문은 WLAN에 이용되는 상위 6비트 온도계 코드의 전류원 셀 매트릭스와 중간 2비트 온도계 코드의 전류원, 그리고 하위 2비트 이진 가중치 코드의 서브 블록으로 구성된 10비트 210MHz의 CMOS 전류구동 디지털-아날로그 데이터 변환기(DAC)을 설계하였다. 제안된 새로운 글리치 억제회로는 입력된 신호의 교차되는 위치를 조절함으로써, 글리치 에너지를 최소화하도록 설계하였다. 또한 제안된 10비트 DAC는 CMOS $0.35{\mu}m$ 2-poly 4-metal 공정을 이용하여 설계하였으며, 유효 칩 면적은 5mm2이다. 제안된 10비트 DAC 칩의 측정결과, 변환속도는 210MHz, DNL/INL은 각각 ${\pm}0.7LSB/{\pm}1.1LSB$이며, 글리치 에너지는 $76pV{\cdot}sec$이고, SNR은 50dB, SFDR은 53dB((a)200MHz), 전력소비는 83mW((a)3.3V)로 측정되었다. This paper describes a 10-bit 210MHz CMOS current-mode Digital-to-Analog Converter (DAC) consisting of 6 bit MSB current cell matrix Sub-DAC, 2 bit mSB unary current source Sub-DAC, and 2 bit LSB binary weighting Sub-DAC for Wireless LAN application. A new deglitch circuit is proposed to control a crossing point of signals and minimize a glitch energy. The proposed 10-bit CMOS current mode DAC was designed by a $0.35{\mu}m$ CMOS double-poly four-metal technology rate of 210MHz, DNL/INL of ${\pm}0.7LSB/{\pm}1.1LSB$, a glitch energy of $76pV{\cdot}sec$, a SNR of 50dB, a SFDR of 53dB at 200MHz sampling clock and power dissipation of 83mW at 3.3V

Lim, Shin-Il,Kim, Jin Woo,Yoon, Kwang-Sub,Lee, Sangmin The Institute of Electronics and Information Engin 2013 Journal of semiconductor technology and science Vol.13 No.2

This paper describes a low power asynchronous successive approximation register (SAR) type 12b analog-to-digital converter (ADC) for biomedical applications in a 0.35 ${\mu}m$ CMOS technology. The digital-to-analog converter (DAC) uses a capacitive split-arrays consisting of 6-b main array, an attenuation capacitor C and a 5-b sub array for low power consumption and small die area. Moreover, splitting the MSB capacitor into sub-capacitors and an asynchronous SAR reduce power consumption. The measurement results show that the proposed ADC achieved the SNDR of 68.32 dB, the SFDR of 79 dB, and the ENOB (effective number of bits) of 11.05 bits. The measured INL and DNL were 1.9LSB and 1.5LSB, respectively. The power consumption including all the digital circuits is 6.7 ${\mu}W$ at the sampling frequency of 100 KHz under 3.3 V supply voltage and the FoM (figure of merit) is 49 fJ/conversion-step.

可罰的 違法性의 理論 및 效用性에 關한 硏究

朴光燮 충남대학교 대학원 1977 論文集 Vol.8 No.-

This study aims to investigate the "Strafbare Rechtswidrigkeit" recently discussed in Japan. The "Strafbare Rechtswidrigkeit" depends on the theory which a certain behavior need not to be charged to punishment despite its illegality, because of the slight damage it commits. Such a behavior can escape the punishment for the crime liability by reason of the lack of punishableness the consititutional factors of the criminal law expect. Just as the theory of "Zumtbarkeit" was brought forward through the efforts to get rid of the formal interpretation of the law in Germany of disorder after the First World War at the beginning of the twentieth century, so this theory is resulted from the realization of practical efforts to preserve the rationality of the right to punish. This study concentrates in the light of judicial precedents on the theoretical structure of the "Strafbare Rechtswidrigkeit", together with the discussion on the effectiveness to the practical use. The contrast between the rejecting opinion on the theory organizer of the "Strafbare Rechtswidrigkeit" and a system of crime is focussed from the theoretical viewpoint on: 1) the estimation of material illegality of the behavior before a crime is committed, and 2) the estimation of material illegality on the stage of illegality itself. The former estimation, however, embraces the questions to be considered the contradiction in the traditional system of crime ("Tatbestand-Rechtswidrig-Verant-wortlichkeit"). What is the criterion which takes this theory for granted then? The criterion of the unpunishable trifling behavior is based on the slightness of damage, and the behavior reasonableness recognized by the common opinion of the society. The diverse criticism should be done to the theory of "Strafbare Rechtswidrigkeit" organized by fundamental. 1) The protective function of the criminal law is likely to fall in danger of interpretativ waywardness by a person in charge of the case. 2) The conditions can be dealt with as a factor which will determine a crime constitution. 3) This theory is not necessarily to be adopted to practical use because of the possible decision of the insignificant case by means of the pertinent application of suspension of indictment. 4) The prosecutor's burden to prove the quality of the crime is tend to make the case delayed. The application of "Strafbare Rechtswidrigkeit" could be criticised from the various points of view, but no objection will, I think, be brought forward to the purport and effort of the advocators who virtually interpret the complicated social phenomena in favor of the appropriate and resonable adoption of the punishment. This theory should, therefore, be appreciated for its scientific significance and value that explored what foundation and limit of the capacity of punishment it has which has not yet been studied firmly. The Introduction of this theory to practical use in our country seems not to have a good practical effect because there is a difference of the legislation between Japan and Korea (whose criminal law has the system of conditional release and the stipulation of Article 20) as it was discussed in my formerly investigation of judicial precedents. I admit, before going into the controversy on the theory itself, that the theoretical ideas primarily has its good effectiveness to practical use form the motives of the theory.

The prupose of this study was to examine the effects of the fibrin adhesive (Beriplast??) on healing of full-thickness wounds in the rat's hard palate. Twenty Spraque-Dawley strain white male rats, each weighing 250-300 gm were used. Creation of full-thickness wounds of 4 × 4 mm in size were performed on the hard palate. Beriplast??, a wound dressing material , was applied immediately in the experimental group, but not applied in the control group. All wounds were protected with palatal resin splints. The animals were sacrificed on the 2nd, 4th, 7th, 14th, and 28th day after the operation for macroscopic and microscopic examinations. Results obtained were as follows ; 1. On the 7th day after the operation, epithelial proliferation was greater in the experimental group than that in the control group. 2. The inflammatory reaction of the experimental group was less than the control group on the 2nd and 4th day after the operation. Beriplast?? was resorbed on the 7th day after the operation. 3. In the control group, the epithelial proliferation occurred from the 7th to the 14th day after the operation, and in the experimental group, epithelial proliferation occurred from the 4th day after the operation. 4. On the 14th and 28th day after the operation, there was no prominent difference between the two groups in histological findings. These results suggest that the use of fibrin adhesive (Beriplast??) as a palatal wound dressing results in greater epithelial proliferation and less inflammation in the early stage of wound healing.
