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.

Lipomyelomeningocele is the most common malformation leading to spinal cord tethering. Nonetheless, these lesion continues to pose a challenge in patient management. The purpose of this study was to identify the clinical feature, candidate for surgical repair, and outcome of lipomyelomeningocele in young children and adults. We studied the magnetic resonance images and/or lumbar myelo-CT of lipomyelomeningocele performed between January 1987 and September 1995 at our institutions and reviewed the pertinent medical records and radiologic studies to determine clinical feature, surgical candidate, and outcomes of these patients. Of the 14 cases(11 female and 3 males) studied, the most common factor that caused these patients to seek help was the cosmetic effect of the mass on their back, followed by urinary incontinence, and weakness of lower extremities. The patients' age ranged from 2 months to 21 years(mean, 5.0 years). All the patients underwent immediate surgical management that consisted of removal of lipoma, untethering of the cord, and complete dural sac repair. Follow up for these patients ranged from 6 to 82 months(median, 54 mo). None of the patients that underwent surgical correction before the emergence of neurological deficit had ever developed neurological deficits at the end of the follow up. However a few of the patients, despite presented with neurological deficits or urinary incontinence at the time of surgery, improved significantly. In conclusion, early detection and prophylactic surgery is imperative to prevent permanent neurological deficits and urinary dysfunction.

The purpose of this study is to define the variation of spatial composition in Frank L. Wright's architecture focusing on the houses of Prairie in the early period(1892~1910). The view point of architectural organization, the classified principle of spatial composition be related to the geometric space and the organic space in that period. We select the houses of Frank L. Wright : Blossam House(1892), Winslow House(1893), Heller House(1896), Willits House(1902), Martin House(1904), Coonley House(1907). The result of this study shows that the spatial composition on the houses of Prairie is variated from the linear symmetry to symmetrical axial centripetal and non-symmetric expansion.

This paper presents the robust control of a composite beam using μ-synthesis. The natural frequencies of the composite beam featured by a piezo-film sensor and piezo-ceramic actuator are calculated by using the modal analysis method and then modal coordinates are introduced to obtain the state equations of the structural system. Two-natural frequency were considered in the modelling, because robust control theory which has inherent robustness to structured uncertainty is adopted to suppress the transients vibrations of a glass fiber reinforced(GFR) composite beam. A robust controller satisfying the nominal performance and robust performance is designed using μ-synthesis theory based on the structured singular value. Simulations and experiments were carried out with the designed controller and effectiveness of the robust control strategy was verified by results.

This paper presents the vibration characteristics of an intelligent cantilever beam in contact with fluid using PZT actuator and PVDF film. The effect of liquid level on free vibration of composite beam in a partially liquid-filled circular cylinder is investigated. The dynamic behaviors of a flexible beam-water interaction system are examined. The coupled system is subject to an undisturbed boundary condition in the fluid domain. In the vibration analysis of wetted beam, the decoupled analyses between beam and fluid have been conventionally employed by considering firstly the composite beam vibration in air and secondly performing the correction taking account for surrounding fluid effects. That is, this investigation was to look at how natural frequencies, mode shapes, and damping are affected by liquid level variations. Using the coupled modal reanalysis method employing the governing equations and the clamped-free and free-free boundary conditions, the vibration analysis of beam in contact with fluid is performed. We also carried out the experimental verification about reliability of theoretical methods to inclusive vibration analysis of the fluid-structure system with PZT actuator and PVDF film. It was found that the coupled natural frequencies decrease with the fluid level for the identical composite beam due to added mass effect.

The purpose of this paper is to investigate if KWL model is applied to not only lessons of reading expository text but also any other lessons. For this, we developed KWLA model for lessons of reading persuasive text, KWLE model for lessons of reading narrative text, KPWL model for lessons of speaking and listening, KWWL model for lessons of writing, kwPl model for lessons of inquiry-oriented subjects(social study, science, mathematics etc.), kwAl model for lessons of expression-oriented subjects(athletics, musics, arts etc.) through expanding and transforming basic KWL model. The results are such as : First, we confirmed that KWL model can be applied to not only lessons of reading expository text but also any other lessons of korean language subject if transformed appropriately. Second, we confirmed that KWL model can be applied to not only lessons of korean language subject but also lessons of any other subject if transformed appropriately. Third, we are able to use effectively KWL learning paper in order to assess holistically knowledge about topics and attitudes on learning, products of learning and process of learning etc. This is a kind of performance assessment. But we have to transform the basic KWL model in order to fit to new fields, to operate actively KWL class, and to assist students-initiated learning activity. If not, the effects of KWL model will be reduced to half. 이 연구는 KWL이 설명문 읽기뿐 아니라 다른 분야에도 적용이 가능한지 탐색하는 것을 목적으로 한다. 이를 위해 KWL의 기본 수업 모형을 확대·변형하여, 논설문 읽기 수업을 위해서 KWLA를, 이야기 글 읽기 수업을 위해서 KWLE를, 말하기·듣기 수업을 위해서 KPWL을, 쓰기 수업을 위해서 KWWL을, 사회과·과학과·수학과 등 탐구형 교과의 수업을 위해서 kwPl을, 그리고 체육과·음악과·미술과 등 표현형 교과의 수업을 위해서 kwAl을 만들어 수업에 적용하였다. 그 결과, KWL은 설명문 읽기 수업뿐 아니라 다른 장르의 읽기 수업에도, 읽기뿐 아니라 국어과 내 다른 영역의 수업에도, 나아가 국어과뿐 아니라 여타 교과의 수업에도 적용이 가능하며, 효과 또한 작지 않다는 것을 확인할 수 있었다. 그리고 활동의 결과물인 KWL 학습지는 학습자들의 지식뿐 아니라 태도도, 그리고 학습의 결과뿐 아니라 과정까지도 평가할 수 있게 해 주는 비형식적 수행평가의 자료로 훌륭하게 활용할 수 있다는 점도 확인할 수 있었다. 이와 함께 확대 적용의 효과를 극대화하기 위해서는 모형의 적절한 변형, 교사의 능동적인 역할, 학습자들의 자기 주도적 학습 조장 등의 조건이 갖추어져야 한다는 제언도 하였다.
