The analog image based system consisted of a simulator and medical linear accelerator (LINAC) for radiotherapy was upgraded to digital medical image based system by exchanging the X-ray film with Computed Radiography (CR). With minimum equipments shift and similar treatment process, it was possible that the new digital image system was adapted by the users in short time. The film cassette and the film developer device were substituted with a CR cassette and a CR Reader, where the ViewBox was replaced with a small size PC and a monitor. The viewer software suitable for radiotherapy was developed to maximize the benefit of digital image, and as the result the convenience and the effectiveness was improved. It has two windows to display two different images in the same time and equipped various search capability, contouring, window leveling, image resizing, translation, rotation and registration functions. In order to avoid any discontinuance of the treatment while the transition to digital image, the film and the CR was used together for 1 week, and then the film developer was removed. Since then the CR System has been operated stably for 2 months, and the various requests from users have been reflected to improve the system. 방사선치료를 위한 아날로그영상기반의 시뮬레이터와 의료용 선형가속기로 이루어진 시스템을 X-ray 필름을 Computed Radiography (CR)로 교체하여 디지털영상기반의 시스템으로 개선하였다. 장비교체를 최소화하였고 기존의 치료과정과 유사하도록 하여 사용자들이 짧은 시간에 적응할 수 있도록 하였다. 필름카세트와 필름현상기는 CR카세트와 CR리더기로 대신하였고, ViewBox는 소형PC와 모니터로 대체되었다. 디지털영상의 장점을 충분히 활용하기 위해 방사선종양학과에 적합한 Viewer 소프트웨어를 개발하여 업무의 편리성과 효율성을 도모하였다. Viewer 소프트웨어는 2개의 이미지를 동시에 볼 수 있으며, 이들 영상의 비교도 가능하다. 다양한 검색기능과 Contouring 기능, 윈도우폭/레벨 조절기능을 갖추었다. 업무의 중단이 없도록 하기 위해 1주일간 기존 필름과 CR을 공동으로 운용하며 문제점을 수정한 후 필름시스템을 제거하고 CR시스템을 운용하였다.

The fractions of Uncariae Ramulus et Uncus seemed to be closely related with the levels of amino acids and other components which concerns with formation and metabolism of neurotransmitters in brain. The pretreatments of methanolic extract and its fractions prohibited the pentylenetetrazole (PTZ) induced convulsion. In such cases, lowered levels of ${\gamma}-aminobutyric$ acid and glutathione in brain were significantly recovered. And also the increased levels or activities of lipid peroxide, ${\gamma}-aminobutyric$ acid aminotransferase, xanthine oxidase, aldehyde oxidase, superoxide dismutase, catalase and glutathione peroxidase by PTZ-convulsion were lowered to normal state.

한국${\cdot}$일본 전통건축공간의 지향성

As a circumstantial-existance character (the human character who takes action after grasping circumstances and fears things with reason) the Japanese were more interested in the active doctrines of Wang Yang-ming than other speculative studies. All of people were inhumanely incorporated into the rigorous class system under pressure in the samurai society. In the atmosphere of the society a natural phenomenon was understood as the ksana of change, and instead of the whole, the part was mainly described with emphasis on the reality. Therefore nature came near to the man after being reduced and then was symbolized in the Interior space. Also the classification of spaces, that is to say, the settlement of borders by the social position was shown in the great interior space like a labyrinth. As a self-existance character(the human style who carves out for and does not have a regard other's feeling), however, the Korean were much influenced by the Taoist Idea as they tried to be similar to nature in nature itself. Therefore the idea of Asaniskrota was in their origin. There was a tendency for space to be extended toward the outdoor in Korea, since the Korean people who are speculative and like to be natural tried to be close to nature. Therefore the division of spaces according to class and sexuality and the settlement of borders were already shown in outside by Che-Na-Num(Divided-Mass:Koren's own style). These are closely related with that houses were built after a village settle down in Korea while built before a village settle down in Japan. Architectural space consists of the interior and the exterior. The layout and (on of architectural space has a great variety of characters by region and culture. In other words, it can be understood which has a priority between the interior and the exterior in developing the layout and the form of architectural space. Belonging to the culture area of Chinese characters with Korea, Japan has maintained its own Identity. It has an identity in the layout and form of architectural space as well. Therefore, the architecture and architectural theories of the two countries were compared and analyzed with priority given to the traditional architecture, also the backgrounds of architecture and architectural theories of two countries were examined in this study. This study shows that each country has different characters in how to introduce nature, how to expand space and how to compose windows, including the view of nature and the cult of space. As a result, the space in Korean architecture has relatively the exterior-oriented character but in Japan architecture spatial character is interior-oriented. The interior-oriented character can be relevant to the word 'reduction' and the exterior-oriented character to 'extension' after all. Also it can be thought that each character has a great relation with climate and idea of people in power.

In general, the function of university dormitory includes residental, educational and many other functions for students who need quite environment and energetic living life. This functions influence the residental satisfaction of university dormitory. So this study attempts to evaluate many functions of the D-university dormitory according to the residents (students) needs and satisfaction. In the present work, SPSS window version 12.0 programs Anova (duncan, scheff, T-test. etc.) was used for analysis of statistical data which obtained from survey. The field surveys carried out for a total samples of 159 residents such as male (86), female (73), in the D-university dormitory. The result appears that the most dissatisfied factor of resident was the space and facilities of wash room. and students demand that various room and program in the dormitory except main space (unit room).

Radio Frequency 회로 모듈 BGA(Ball Grid Array) 패키지

김동영,정태호,최순신,지용,Kim, Dong-Young,Jung, Tae-Ho,Choi, Soon-Shin,Jee, Yong 대한전자공학회 2000 電子工學會論文誌-SD (Semiconductor and devices) Vol.37 No.1

We presented a BGA(Ball Grid Array) package for RF circuit modules and extracted its electrical parameters. As the frequency of RF system devices increases, the effect of its electrical parasitics in the wireless communication system requires new structure of RF circuit modules because of its needs to be considered of electrical performance for minimization and module mobility. RF circuit modules with BGA packages can provide some advantages such as minimization, shorter circuit routing, and noise improvement by reducing electrical noise affected to analog and digital mixed circuits, etc. We constructed a BGA package of ITS(Intelligent Transportation System) RF module and measured electrical parameters with a TDR(Time Domain Reflectometry) equipment and compared its electrical parasitic parameters with PCB RF circuits. With a BGA substrate of 3${\times}$3 input and output terminals, we have found that self capacitance of BGA solder ball is 68.6fF, and self inductance 146pH, whose values were reduced to 34% and 47% of the value of QFP package structure. S11 parameter measurement with a HP4396B Network Analyzer showed the resonance frequency of 1.55GHz and the loss of 0.26dB. Routing length of the substrate was reduced to 39.8mm. Thus, we may improve electrical performance when we use BGA package structures in the design of RF circuit modules. 본 논문은 RF 호로 모듈을 구현하기 위한 방법으로서 BGA(Ball Grid Array) 패키지 구조를 제시하고 그 전기적 변수를 추출하였다. RF 소자의 동작 주파수가 높아지면서 RF 회로를 구성하는 패키지의 전지적 기생 성분들은 무시할 수 없을 정도로 동작회로에 영향을 끼친다. 또한 소형화 이동성을 요구하는 무선 통신 시스템은 그 전기적 특성을 만족시킬 수 있도록 새로운 RF 회로 모듈 구조를 요구한다. RF 회로 모듈 BGA 패키지 구조는 회로 동작의 고속화, 소형화, 짧은 회로 배선 길이, 아날로그와 디지탈 혼성 회로에서 흔히 발생하는 전기적 기생 성분에 의한 잡음 개선등 기존의 구조에 비해 많은 장점을 제공한다. 부품 실장 공정 과정에서도 BGA 패키지 구조는 드릴링을 이용한 구멍 관통 홀 제작이 아닌 순수한 표면 실장 공정만으로 제작될 수 있는 장점을 제시한다. 본 실험은 224MHz에서 동작하는 ITS(Intelligent Transportation System) RF 모튤을 BGA 패키지 구조로 설계 제작하였으며, HP5475A TDR(Time Domain Reflectometry) 장비를 이용하여 3${\times}$3 입${\cdot}$출력단자 구조을 갖는 RF 모튤 BGA 패키지의 전기적 파라메타의 기생성분을 측정하였다. 그 결과 BGA 공납의 자체 캐패시턴스는 68.6fF, 자체 인덕턴스는 1.53nH로써 QFP 패키지 구조의 자체 캐패시턴스 200fF와 자체 인덕턴스 3.24nH와 비교할 때 각각 34%, 47%의 값에 지나지 않음을 볼 수 있었다. HP4396B Network Analyzer의 S11 파라메타 측정에서도 1.55GHz 근방에서 0.26dB의 손실을 보여주어 계산치와 일치함을 보여 주었다. BGA 패키지를 위한 배선 길이도 0.78mm로 짧아져서 RF 회로 모튤을 소형화시킬 수 있었으며, 이는 RF 회로 모듈 구성에서 BGA 패키지 구조를 사용하면 전기적 특성을 개선시킬 수 있음을 보여준 것이다.

The ethyl acetate fraction of Uncariae Ramulus et Uncus, which showed anticonvulsant effects against pentylenetetrazole (PTZ) treated mice, were subjected to column chromatography to isolate ursolic acid and hyperin from active eluate. Hyperin decreased the elevated activities of GABA-T and xanthine oxidase and lipid peroxide level dose-dependently in PTZ treated mice brain tissue in vitro, but no effect on superoxide dismutase activity. The effects on such enzyme and component seemed to be related with biosynthesis or metabolism of neurotransmitters.
