Fault detection is necessary for yield enhancement and cost reduction in semiconductor manufacturing. Sensory data acquired from the semiconductor processing tool is too large to analyze for the purpose of fault detection and classification(FDC). We studied the techniques of fault detection using statistical method. Multiple regression analysis smoothly detected faults and can be easy made a model. For real-time and fast computing time, the huge data was analyzed by each step. We also considered interaction and critical factors in tool parameters and process.

인간의 두뇌에서는 갖가지 다양한 형태의 입력들을 이용하여 동시에 여러 가지의 판단, 추론 및 기억 등의 기능을 수행한다 이러한 이유로 인간 두뇌는 거대한 지능형 정보처리기라고 할 수 있다 현재 정보처리 메커니즘은 다양한 형태로 발달되고 있지만 그 중에서도 지능형 정보처리 메커니즘으로는 소프트 컴퓨팅 기법을 응용한 것이 대부분이다. 본 논문에서는 소프트 컴퓨팅 기법을 이용하여 두뇌에서의 시각, 청각의 정보처리 과정을 하나의 구조로 모델링하고자 한다. 시각에서의 정보와 청각에서의 정보는 각기 다른 모듈에서 처리되는 방식을 취하고 있으며, 최종적으로 두 감각 정보를 이용한 처리가 가능하도록 모듈형태의 전체적인 구조를 지니고 있다. 상이한 두 가지의 정보를 동시에 처리하는 과정을 모델링함으로써 복잡한 문제의 해결 및 다양한 경우에 대한 고려를 수행하여 인간 두뇌 모델링의 기초를 마련하고자 한다.

The Halliwick concept was developed by James McMillan over 50 years ago, and began as a method for teaching swimming to children with physical disables. After that the Halliwcik concept was developed as a specific strategy(called the Ten-Point Program) for teaching swimming to children with disabilities. Soon after the changes in the physical and emotional behavior were attributed to a unique teaching/learning philosophy and a psycho-sensory-motor learning program that is enhanced by hydrodynamics. Recognizing the therapeutic effects of the Ten-Pont Program adapted the program as a therapeutic intervention called Water Specific Therapy or the Logic Approach to Therapy in Water.

Eosinophilic myelitis (EM) or atopic myelitis is a rare disease characterized by a myelitic condition in the spinal cord combined with allergic process. This disease has specific features of elevated serum IgE level, active reaction to mite specific antigen and stepwise progression of mostly the sensory symptoms. Toxocariasis can be related with a form of EM. This report describes two cases of cervical eosinophilic myelitis initially considered as intramedullary tumors. When a differential diagnosis of the intramedullary spinal cord lesion is in doubt, evaluation for eosinophilic myelitis and toxocariasis would be beneficial.

This paper presents a novel technology for unattented continuous monitoring of radioactive material in hot cell environments. In this monitoring system, the surveillance camera data and NDA data are time synchronized and integrated into the same dimension through data processing. The integrated information is then fed into a neural network to generate diagnostics through data processing. the integrated information of the concept is tested for a spent nuclear fuel transprotation in an operational hot cell at KAERI. The presented integral part of the multi-sensory system and the analytical paradigm may provide an effective technologyical alternative for safeguarding new conceptual hot cell facilities, namely the Dupic facility.

The method of the squid safe made in Kyungsando was examined, and fermentation precess was established. The chemical composition and functional effects of the squid sikhe were examined. In the sensory evaluation, the squid sikhe made from Gampo accepted to be best for traditional Kyungsangdo squid sikhe and it is called standard sikhe. The Gampo sguid sikhe showed higher values in total sugar, free reducing sugar and nitrogen compound analysis compared to the orthers. The sugar of standard sikhe consisted of four kinds including glucose. The contents of free amino acid was increased in the order of glutamic acid, alanine, and methionine. The composition of amino acid in water or salt soluble protein of squid sikhe contained 17 kinds, and the contents was increased in order of glut amine acid, aspartic acid, and proline.

Over a wireless sensor network (WSN), accurate localization of sensor nodes is an important factor in enhancing the association between location information and sensory data. There are many research works on the development of a localization algorithm over three-dimensional (3D) space. Recently, the complexity-reduced 3D trilateration localization approach (COLA), simplifying the 3D computational overhead to 2D trilateration, was proposed. The method provides proper accuracy of location, but it has a high computational cost. Considering practical applications over resource constrained devices, it is necessary to strike a balance between accuracy and computational cost. In this paper, we present a novel 3D localization method based on the received signal strength indicator (RSSI) values of four anchor nodes, which are deployed in the initial setup process. This method provides accurate location estimation results with a reduced computational cost and a smaller number of anchor nodes.

After many years of proliferation, the nuclear industry is indebted for a formidable consequence, the safe management of spent fuel. Naturally, the high radioactivity involved with such process motivates the development of effective telerobotic systems. Nevertheless, the existing master-slave type of tele manipulators are limited in effectiveness by the human operator's limited sensory and manipulation capabilities. This paper presents the result of a research effort to resolve such problems by assigning the slave manipulator a certain degree of intelligence; sensing and actuation. In the presented system, a perception-action loop is achieved using ultrasonic range sensor and laser distance sensor interfaced with the PUMA 760 industrial robot system, and applied to automating impact wrenching task for unbolting the lid of nuclear spent fuel cask. The perception-action loop performs determination of the cask location, collision avoidance and centering of the impact wrench onto the bolt head. To aid the insertion task and to provide versatility a mounting module consisting of an RCC device and an automatic tool changer is designed and implemented. The performance of the developed system is tested on the model cask and the result is given.

Vision is the most important sensing capability for both men and sensory smart machines, such as intelligent robots. Sensed real 3D world and its 2D camera image can be related mathematically by a process called camera calibration. In this paper, we present a novel linear solution of camera calibration. Unlike most existing linear calibration methods, the proposed technique of this paper can identify camera parameters explicitly. Through the step-by-step procedure of the proposed method, the real physical elements of the perspective projection transformation matrix between 3D points and the corresponding 2D image points can be identified. This explicit solution will be useful for many practical 3D sensing applications including robotics. We verified the proposed method by using various cameras of different conditions.
