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.

In order to lock stability of geotextile filer to clogging or blocking, small scale laboratory tests were accomplished, considering to drainage conditions, on domestic and foreign nonwoven geotextile products used for filter, and permeable capacity of the geotextile filter was analyzed. The results obtained are as follows: 1. The permeable flow rate through the geotextile filter appears to be decrease remarkably in the initial stage of duration time but gradually afterward and is stabilized at 300 hours∼400 hours of duration time. 2. The increase ratio of permeable flow rate through the geotextile filter due to rising hydraulic head appears to be higher with protected soil having lower comparative content of fine particles, and the effect of rising hydraulic head finds to be higher with that protected soil. 3. The permeable flow rate through the geotextile filter appears to be higher with protected soil having lower content of fine particles and the increase of it trends to be considerable and to be decrease according to the elapse of time. From the fact, the flow rate finds to be more influenced by clogging or blocking with protected soil layer having lower content of fine particles. 4. It seems generally that the thicker the geotextile filter is, the higher the permeable flow rate is, but the decrease ratio of it in the initial stage finds to be lower in the case of thicker geotextile.

본 논문에서는 축약 분산 기억 장치(Sparse Distributed Memory, SDM)를 사용한 신경망 호 수락 제어(Call Admission Control, CAC)를 제시한다. 호 수락 제어는 ATM 망 트래픽 제어의 핵심 요소이다. 이것은 ATM 네트워크 환경의 다양한 변화와 빠른 변화에 적응적이어야 한다. 기존의 ATM 호 수락 제어 방식은 가능한 모든 망 분석을 요구한다. 따라서 최적의 설계는 어렵다. 최근 신경망 방식이 이러한 문제를 해결하기 위해서 도입되었다. 그러나 이것 역시 적응적 제어를 제공하지 않았다. 이것은 부가적인 학습 데이터 테이블과 학습 기간을 요구하였기 때문이다. 우리는 CAC 기능 구현에 더 현실적인 SDM을 기반으로 한 신경망 호 수락 제어 방법을 제안하고, 이것을 기존의 신경망 호 수락 제어 방법과 비교했다. 제안된 방식은 급격한 변화에 적응적인 호 수락 제어를 제공한다. 실험 결과 SDM은 별도의 학습 테이블과 싸이클을 필요로 하지 않아, 빠른 적응력과 안정성을 가짐을 확인할 수 있었다. In this paper, we propose a Neural Call Admission Control(CAC) method using a Sparse Distributed Memory(SDM). CAC is a key technology of ATM network traffic control. It should be adaptable to the rapid and various changes of the ATM network environment. Conventional approach to the ATM CAC requires network analysis in detail in all cases. So, the optimal implementation is said to be very difficult. Therefore, neural approach have recently been employed. However, it does not meet the adaptability requirements. Because it requires additional learning data tagles and learning phase during CAC operation. We have proposed a neural network CAC method based on SDM that is more actual than conventional approach to apply it to CAC. We compared it with previous neural network CAC method. It provides CAC with good adaptability to manage changes. Experimental results show that it has rapid adaptbility and stability without additional learning table or learning phase.

This study was carried out to investigate in connection with seeding rate according to the fertilizer application method and water management in direct seeding on flooded paddy surface. The total nitrogen and chlorophyll contents was decreased as increasing amount of seeding. The total nitrogen and chlorophyll contents were high in the strong drainage methods than the custom water management. LAI and dry mater recording where the seeding amount will increase to the fertilizer application method it increases consequently were low tendency from the site which omits the omitted the top dressing at tillering stage. The number of panicles per square metre was increased according to amount of seeding, but the number of spikelets per panicle was decreased. When omitted the top dressing at tillering stage and increasing the amount of seeding, the rice yield was high and amount of seeding was 89 kg per hectare. The results indicate that increasing of seeding rate and omission of fertilizer application with strong drainage at tillering stage was to reduce field lodging degree, to economy of water culture and to save labor for fertilization.

ROTDR 센서의 감지부로는 넓은 면적을 감지할 수 있는 매설형 광섬유 센서 탐지판을 제작하고, 인가된 침입물체의 위치와 무게에 따른신호특성을 고찰하였다. ROTDR 센서는 펄스 폭이 30 ns이고, 광섬유의 길이는 10 km 이상이다. 위치탐지오차는 약 2m 이내였으며, 무게에 따른 탐지능력은 20 kgf, 40 kgf, 60 kgf, 80 kgf의 네 단계를 구분할 수 있음을 알 수 있었다. 넓은 지역에 걸친 침입자의 침투를 감시하기 위하여 수십 km의 광섬유 길이 전체를 감지부로 사용할 수 있는 광섬유 BOTDA 센서를 개발하였다. BOTDA 센서는 한 개의 레이저 다이오드와 두 개의 광전 변조기(electro-optic modulator)를 사용하여 간단하게 구성하였다. 침입자에 의한 광섬유의 변형률 벽화를 탐지하는 실험을 수행하기 위하여 광학테이블 위에 광섬유에 변형률을 인가하기 위한 실험 장치를 설치하여 실험을 수행하였다. 이 실험으로부터 시간간격 1.5 초동안 광섬유 약 4.81 km의 길이를 거리분해능 3 m로 침입자를 탐지할 수 있음을 확인하였다. We have studied the detection techniques, which can determine the location and the weight of an intruder into infrastructure, by using fiber-optic ROTDR (Rayleigh optical time domain reflectometry) sensor and fiber-optic BOTDA (Brillouin Optical time domain analysis) sensor, which can use an optical fiber longer than that of ROTDR sensor. Fiber-optic sensing plates of ROTDR sensor, which are buried in sand, were prepared to respond the intruder effects. The signal of ROTDR was analyzed to confirm the detection performance. The constructed ROTDR could be used up to 10 km at the pulse width of 30 ns. The location error was less than 2 n1 and the weight could be detected as 4 grades, such as 20 kgf, 40 kgf, 60 kgf and 80 kgf. Also, fiber optic BOTDA sensor was developed to be able to detect intrusion effect through an optical fiber of tens of kilometers longer than ROTDR sensor. Fiber-optic BOTDA sensor was constructed with 1 laser diode and 2 electro-optic modulators. The intrusion detection experiment was peformed by the strain inducing set-up installed on an optical table to simulate a11 intrusion effect. I11 the result of this experiment, the intrusion effect was well detected as the distance resolution of 3 m through the fiber length of about 4.81 km during 1.5 seconds.
