During the past decade, motion simulators have been effectively used for studying the vehicle interaction and developing vehicle system and components in highly controlled and repeatable test environment. Most of motion simulator use a six degree of freedom stewart platform driven hydraulically. Thanks to a high performance 3D graphic accelerator, the visual system generates high fidelity visual scenes, which are displayed on a monitor on the motion platform. But this type of motion simulator has a limited rotational motion. In this paper we designed a new type motion simulator for endless rotational motion and controller for it. This has four degrees of freedom, three rotational and one vertical motion. The real-time simulation system, based on a personal computer with a digital signal processor, supervises overall operation of the simulator.

This study is carried out to investigate the water quality change trends in Pusan Metropolitan streams. The temperature of the streams are moderate except in winter period and this can be explained by the Korean meterological characteristics. The pH does not vary by the time but some points are a little low. BOD_(5) and COD_(Mn), the index of water contaminants, be shown as characteristic domestic waste water patterns. The nutrient matters, such as total nitrogen and total phosphate, are appeared to be low. The chronic water quality, as BOD_(5) and COD_(Mn), shows that the loading rates in 1998 are smaller than the past(1983, 1992). Some points show a little high loading in autumn, but this needs more investigation to make clear the cause(s).

21세기의 교육은 교육 정보화를 기반으로 한 연계·통합 교육으로 발전되고 있으며, ICT 활용교육이 교수-학습 전략과 유형을 제시하며, 기술교과의 수업 지도안에 대한 효율적인 XML 문서 생성 및 저장 시스템에 대한 구현 방안을 제시한다. 그리고 이 논문에서 구현된 XML 교수 문서 시스템을 적용하여 교육 자료의 효율적인 관리과 저장성을 높이고, 동일 업무에 대한 교육 자료의 재편집 과정을 감소시킴으로써 교육 자료의 가치를 높일 수 있는 가능성을 확인하였다. The education of 21st century is developed to the closely connected and integrated education, and the ICT applied education is suggested as an approach to teaching-learning method. In this paper, we suggest an teaching-learning pattern and strategy of Technology course as an example of the ICT applied education, and provide an implementation for the efficient XML document creation and storage system of teacher’s subject data. And we have confirmed the utilization of this system which it improves the efficient management and preservation of educational data and also it raises the value of educational data by decreasing the burden of re-editing the educational documents for similar business.

Transparent organic-inorganic hybrid material was synthesized via the sol-gel method using polyethylene-co-methacrylic acid(PEMA) ionomer and a metal alkoxide, tetraethylorthosilicae(TEOS). The resulting material was characterized using ^(29)Si solid-state nuclear magnetic resonance spectroscopy results prove that silica is formed via the sol-gel reaction. Scanning electron microscopy analysis (SEM) , transmission electron microscopy (TEM) studies indicate that silica particle size is in nanoscopic level (70nm average size), and silica nanoparticles are uniformly dispersed in the polymer matrix after the sol-gel process. Theremogravimetric analysis (TGA) results show that the silica content of the hybrid. The thermal stability of the ionomer increases after hybridization. Material testing machine of the hybrid shows that the stress of ionomer increase after the sol-gel reaction.

박종태,신경진,양윤석,우광만,이숭덕,이승환,이정빈,정연보,조승희,한길로,한면수,홍승범 大韓法醫學會 2001 대한법의학회지 Vol.25 No.1

This paper described a collaborative exercise intended to see what kinds of short tandem repeat (STR) loci are used in different DNA typing laboratories in Korea and to compare their results for the demonstration whether uniformity of DNA profiling results from different laboratory could be achieved in Korea Laboratories were asked to test five tissue DNAs using methods routinely used in each laboratory and to report the results to the coordinating laboratory. The exercise demonstrated that each laboratory was using different STR loci for the typing with different STR numbers,2 VNTRS,36 STRs and amelogenin in total, and the direct comparison of the results from all the laboratory for the 18 loci could not be done as only one laboratory submitted typing results. Among 21 loci for which several laboratories submitted typing results, results for 14 loci were the same and results for the other 7 loci were different depending on the participating laboratory. D1S80, F13A01, D16S539, D21S11, D18S51, D3S1744 were the loci with different typing results. Even in the cases where commercial kits were used, the results were not the same depending on the machines used, that is the capillary electrophoresis or the gel based electrophoresis. The reason for the different results, points about the standardization of the methods arid the profiling data were described.

Objective: The lumbar spinal canal can be devided into the central zone and the lateral zone. The divisions of the lateral zone are the subarticular, the foraminal, and the extraforaminal zone. A common causes of the operation for the spinal stenosis are related to the association with the spondylolisthesis and the central stenosis. There is a paucity of data, however, regarding the operative intervention in the lateral zone stenosis(LZS). Our aim was to analyze the surgical result by the anatomical type and the operative method. Methods: 72 patients of LZS excepting the association with the spondyolisthesis have been operated by six neurosurgeons of our hospital from 30th April, 1994 through 30th September, 2002. The patients had been interviewed about surgical result through telephone by third party persons. The surgical results were analyzed by the four score rating system: ① medication, ② ADL(Ability of daily living), ③ the degree of improvement, ④ the degree of satisfaction. Results: Among 72 patients, there were 25 males and 47 females. The age group of the patients were in their thirties(1), forties(9), fifties(21), sixties(36) and seventies(5). Surgical methods were used on decompression(22), posterior lumbar interbody fusion(PLIF) with cage(1) and PLIF with transpedicular screw fixation system(49). The types of stenosis were subarticular(24), foraminal(16) and extraforaminal(30) and double crush(2). The overall surgical results were Excellent(18), Good(34), Fair(19), and Poor(1). The Non-success rate according to the methods of surgery were decompression(34.8%), PLIF with transpedicular fixation system(24.4%). The overall success rate was(53/72: 73.6%). The success rate according to the types were subarticular(17/24: 70.8%), extraforaminal(21/30: 70%), and foraminal(12/16: 75%). Conclusion: It is suggested that the result was more favorable on the cases of lateral zone stenosis operated with PLIF and transpedicular fixation system. According to the method used, the success rate of decompression was worse than PLIF with transpedicular fixation system.

Gastric small cell carcinoma(SCC) is defined as poorly-differentiated neuroendocrine tumor of the stomach, and their morphologic and biologic features arc similar to those of the lung. It is known that this tumor has poor prognosis even in early pathologic stage, It acounts for only 3% of all gastrointestinal SCC. that has been reported only 33 cases outside and 6 cases inside of the comitiy. Most of these reports are related to advanced gastric SCC. as pathologic stage IIIb or IV. This report describes a case of early gastric SCC. pathologic stage Ib.

Among the inpatients, the diagnosis of neurosis was also the most frequent one, followed by transient situational disturbances, epilepsy, schizophrenia, in order. 7. The number of visiting the outpatient clinc was greater in the patients whose medication were prescribed, compared with the patients whose medication were not prescribed.
