준 생산용 퇴비화 장치를 이용하여 생분해성 플라스틱을 포함하는 유기성 도시생활쓰레기기의 퇴비화를 연구하였다. 유기성 도시생활쓰레기는 실제 도시생활쓰레기 구성비에서 무기물을 제외한 유기성 물질만의 비로 만들어 사용하였다. 유기성 도시생활쓰레기를 구성하는 각각의 물질에 대한 생분해도를 ISO법으로 측정하였고, 퇴비의 화학적 물리적 특성도 조사하였다. 구성 물질에 대한 생분해도 결과에서, 생분해성 고분자를 포함한 각 물질들은 퇴비화에 충분한 생분해도를 나타내는 것으로 밝혀졌다. 또한, 유기성 도시 생활쓰레기로부터 비독성의 퇴비를 얻을 수 있음을 알았다. The composting study of organic municipal solid waste containing biodegradable plastic was performed by using pilot scale composting apparatus. The organic municipal solid waste(OMSW) was artificially prepared for composting. The composition of artificial OMSW was the same as that of real municipal solid waste excluding inorganic waste. The biodegradability of individual component of OMSW was studied according to the ISO method. The chemical and physical characteristics were also observed. Biodegradability study revealed that every component of OMSW including biodegradable plastic had sufficient degradability for real composting. And it was found that non-toxic compost could be produced from OMSW containing biodegradable plastic.

In this paper, we apply the controller output error method to the adaptive fuzzy control design. This method employs a gradient descent algorithm to minimize a error function which is beased on the error at the controller output. This contrasts with more conventional methods which use the error at the plant output. The error function is minimized by adapting some or allof the parameters of the fuzzy controller. In this paper, we propose to revise the consequent parameter. The proposed adaptive fuzzy controller is applied to the adaptive control of a nonlinear plant and is shown to be capable of providing good overall system performance.

Aerobic composting apparatus was set up using International Organization for Standardization(ISO) and ultimate biodegradability of plastic films was evaluated by measurement of released carbon dioxide at the end of test. Test materials were polycaprolactone(PCL), PCL/starch composite with various composition, photo-degradable, bio-destructible film, and high density polyethylene(HDPE) film. After 45 days, PCL and PCL/starch(70/30) composite films were degraded to 37% and 60%, respectively. This fact revealed that starch in PCL elevated the biodegradability of matrix PCL. Although photo-degradable and bio-destructible films also evolved carbon dioxide, matrix polymer(HDPE) was not degraded by microorganisms in compost. This fact was indirectly supported thermogravimetric analysis and morphology of film before and after composting.

In mobile communication systems, location information services of mobile staion cover a variety of areas in E119 services, safety of Alzheimer's patients and traffic control in city, etc. In metropolitan environment, NLOS bias makes some errors taking a measure of diatance between mobile sations and base sations. This paper is to track mobile stations in common communication network nuder NLOS environment. When taking measure of distance, we estimate position by TOA method which remaking LOS environment by removing NLOS bias in measured data adn correcting standard noise by appling Kalman filter.

Due to the rugged energy function of the original Hopfield networks, the output is usually one local minimum in the energy function. This paper an analysis on the location of local minima in Hopfield networks and discribes modified network architecture to eliminate local minima. This modified Hopfield networks has been successfully applied to the construction of analog-to-digital converter with optimal solutions. Experimental results on the voltage transfer characteristics of data converter is presented.

In mobile communication systems, location information services of mobile station cover a variety of areas in E119 services, safety of Alzheimer's patients and traffic control in city, etc. In metropolitan environment, NLOS bias makes some errors taking a measure of distance between mobile stations and base stations. This paper is to track mobile stations in common communication network under NLOS environment. When taking measure of distance, we estimate position by TOA and TDOA method which remaking LOS environment by removing NLOS bias in measured data and correcting standard noise error by appling Kalman filter.
