It is possible not only to treat high concentration organic matter such as food wastes but also to utilize food wastes as resources according to the bio-energy generation such as methane. The method of co-digestion of mixed wastewater mixed with organic wastes such as sewage sludge concentrated waters together with drinking wastewater is the most ideal method. Radiation not only has germicidal power in water treatment, but also is effective in decomposing degradable organic matter. Second chemical contamination problem is also solved because it does not use chemicals. Introduction of radiation pretreatment system to solve problems caused by mixing of waste water and organic waste resources. Biological electrochemical fusion system is used to remove the nutrients contained in the organic matter-removed mixture. Through the development of a system for treatment of high concentration wastewater, the processing efficiency is verified through the universal water treatment system for wastewater containing high concentration organic matter in addition to treatment of wastewater.

The paper describes the development of a new automatic wrapping machine using paper films as it has not been used so far. The most of the automatic wrapping machine have used the vinyl film causing environmental pollution, the paper films, however, have a weak point in the aspect of high temperature adhesion. Therefore, the mechanism of the existing wrapping machine should be altered to prevent it from curling effect through the technical know-how. A new method and technology reducing the curling effect in the automnatic wrapping machine are demonstrated by using developed blower. Thus it is exqection and will decrease environmental pollution.

Authors administered a questionnaire to 300 clients visited to the K University Hospital during August in 1992 to investigate the degree and related factors of consumer's satisfaction with the hospital services. Clients consisted of 82 in-patients and 158 out-patients, 52.4 percent of them was male. Four dimensions of satisfaction were assessed which were medical management, administration, environment and attitude. In-patients reported as dissatisfied with the waiting time during receipt, investigative medical procedures and pharmacy (64.7%), lack of conveniency facilities for patients and their guardians(48.8%) and provision of conveniency facilities in the ward(42.4%), unsanitary state of out- and in-hospital(41.5%). Out-patients reported dissatisfaction with the course of medical management and the time needed(70.3%), the waiting time during receipt, investigative medical procedures and pharmacy(68.3%), lack of conveniency facilities for patients and guardians(42.4%). But both in-patients and out-patients were satisfied with medical equipments, doctor's diagnosis reliability and medical effects, technician's attitude more than 50%. Canonical correlation analysis was done to find related sociodemographic factors to the four dimensions of satisfaction. Of the four canonical functions, the first was only statistically significant in in-patients. Its eigen value was 0.56 and its canonical correlation coefficient was 0.60. Satisfaction with environment and medical management was selected as important concept in dependent variables. Standardized canonical function of environment and medical management were 0.76 and 0.35 respectively. It was related with woman with high educational attainment and increasing number of hospital visits. In out-patients, the first, second and third function were statistically significant and their eigen values were 0.18, 0.4, 0.08 respectively which were small compared to those of in-patients. Their canonical correlation coefficient were 0.40, 0.35, 0.28 respectively. Low degree of environment but high degree of medical management satisfaction was noted in the first function which was related with old age, woman and professional occupation. Low degree of satisfaction with administration(second function) was related with city resident, non-professional occupation and young age. High degree of medical management but low degree of administration satisfaction(third function) was related with surgical visitor, man and non-professional occupation. The direction of hospital managerial strategies could be planned and general characteristics of dissatisfactory clients might be suggested with these results.

로봇주행을 위한 장애물 탐지 및 거리측정 Ⅱ

김태홍,권갑현,전용식 동양대학교 2001 동양대학교 논문집 Vol.7 No.1

자율 주행 이동 로봇에서 사용될 것을 목표로 미지의 장애물을 탐지하고 그 장애물까지의 거리를 측정하는 시스템을 레이저, CCD, 삼각측량법을 이용하여 소형 경량으로 구현하였다.송신부에서 스캐닝 레이저빔을 이동 로봇 높이의 수평면으로 발사하고 수신부에 있는 한 대의 CCD카메라로 전방의 영상을 촬영한다.삼각측량법을 이용하여 장애물까지의 거리를 측정하기 위해서는 송신부와 수신부 사이의 거리, 송신부에서 본 장애물의 각도, 수신부에서 본 장애물의 각도가 필요하다.송신부의 레이저빔 발사 각도는 이를 구동하는 스텝핑 모터의 회전량 제어 펄스 수에 정비례하므로 공급한 펄스 수로써 구하고 수신부에서 본 장애물의 각도는 카메라영상에서 빙의 위치가 영상의 중앙으로부터 몇 픽셀 떨어져 있는가를 계산하여 측정한다.카메라의 영상은 미디언 필터를 거쳐서 잡음 제거 후 소벨 에지 검출 기법을 적용하여 에지를 검출한다.CCD의 상이 맺히는 위치에 따라 왜곡 오차가 발생하는데 이는 CCD의 시야가 넓을수록 커진다.그러나 이 오차는 계산이 가능하기 때문에 보정할 수 있고 초점거리가 짧으면 다른 오차에 비하여 무시 할만하다.이방법은 근거리에서 초음파 방법보다 정밀한 거리측정값과 우수한 공간 분해능을 가진다. A range measuring system was implemented using laser, CCD and triangulation for autonomous mobile robot located in unknown environment.A scanning'laser beam was introduced as a transmitter which sweeps a horizontal plane. To measure the distance to the obstacles, three parameters are necessary, which are the distance between laser transmitter and receiver, the angle of transmitter, and the angle of receiver to the obstacle.At the transmitter, the angle is measure by counting the number of pulses supplied to the stepping motor of laser.At the CCD camera, the angle was measured by counting the number of pixels from the center of image.The image was pre-treated by median filter to eliminate noises.The edge was detected by Sobel technique in the next step. The distortion error occurred at the CCD is proportional to the angle of view of the camera.However, the magnitude of distortion can be calculated accurately, therefore it can be eliminated from the system error by calibrating This method has better spacial resolution and accurate measurement of distance comparing to the supersonic method.

The purpose of this research is to evaluate indoor office environment using the concentrations of nicotine, 3-enthenyl-pyridine(3-EP), and respirable suspended particulate(RSP), which are indicators for environmental tobacco smoke(ETS) and the correlations between indicators and environmental conditions(smoking density, smoking index). The mean air charge per hour (ACH) in smoking rooms was 10.4 and most of the smoking rooms showed non-compliance withe ASHRAE standard value except only one smoking rooms. The concentrations of RSP, 3-EP, nicotine showed log=normal distributions, and became different statistically depending on smoking condition(p〈0.01). The geometric mean concentration of RSP in smoking room was 441.7 ug/㎡ that is far exceeded environmental standard(150 ug/㎡). This implies that fine particulate in smoking room should be carefully controlled considering smoking density and ventilation fate. The mean concentrations of nicotine and 3-EP were 93.4 ug/㎥, respectively. The correlation coefficients between RSP and SI, 3-EP and SI, and Nicotine and SI were 0.67, 0.84 and 0.74, respectively. The correlation coefficient between nicotine and 3-EP, nicotine and RSP, and RSP and 3-EP were 0.76,0.78 and 0.57 respectively.

This paper proposes the rule-based expert system with auto-turning of PID controller gain and shows the efficiency of fuzzy expert system for the speed control of BLDC motor. The PID controller gain tuned using RZN(refined ZN) formula to initial tuning and fuzzy expert system to subsequent tuning. The fuzzy expert PID control method proposed in this paper results in the reduction of overshoot, the rapid response and the robustness for disturbances and noise.

The currenty offered experiment courses are completely reconsidered and reconfigured. The whole subjects are divided into 10 seperate courses, each of which should represent either basic or advanced stages of differing fields of the electronic engineering. It has been aimed that the courses form an elaborate hierachy so that they are minimally redundant but linked to one another in their fringes. Also, it has been pursued that the new courses should not fall obsolete in at last next five years exploring the maximum possibilities of the currently available equipments.
