In a 36-month period, 23 selected Patients with Acute Cerebral Infarction were studied utilizing Computerized Tomography, Barthel Index in an attempt to correlate Brain Computerized Tomography findings with 1week, 4weeks rehabilitation and evaluate the influences of the size and location of the lesion. The study suggested that the size of the lesion had impact on 4 weeks rehabilitation. There was significant different between the patients with Middle Cerebral Artery Pial Territory Infarction(I.P.B.M.C.A.) lesion and the patients with Lacunar Infarction(L.I.), Striatocapsular Infarction(S.C.I.), Internal Watershed Infarction(I.W.I.) lesion, but there was no significant difference between the patients with L.I. lesion and the patients with S.C.I. lesion and the patients with I.W.I. lesion. The size and location of the lesion should be considered together in predicting the functional outcomes of Acute Cerebral Infarction.

In this paper, I present a MPEG4 decoding system modeling in SystemC, a new C/C++ based system simulation approach, In the modeling, MPEG4 decoding behavior is modeled and verified. And I partitions the MPEG4 decoding system into several hardware components which will be implemented at low level hardware design flow and I model a synchronized hardware block communication through data ports.

In the study, PPTMDSO(plasma-polymerized tetramethyldisiloxane) films were deposited on on glass substrate in a paralled plate reactor. As the function of RF power increased from 20 W to 110 W, and the substrate temperature increased from $25^{\circ}C$ to $100^{\circ}C$, the deposit ion rate, increased. When oxygen was intentionally added in monomer vapor, the concentration of Si-O-Si bonds increased while C-H, Si-H, -CH3, Si(CH3)x, -CH3, and Si-C bonds decreased in IR spectra. Thermal stability of PPTMSDO film were investigated and weight loss at $800^{\circ}C$ was 7.3 %.

This paper aims to develop an optimized inventory management method for safety critical Instrument and Control (I&C) components. In this regard, the paper focuses on estimating the consumption rate of I&C components using demand forecasting methods. The target component for this paper is the Foxboro SPEC-200 controller. This component was chosen because it has highest consumption rate among the safety critical I&C components in Korean OPR-1000 NPPs. Three analytical methods were chosen in order to develop the demand forecasting methods; Poisson, Generalized Linear Model (GLM) and Bootstrapping. The results show that the GLM gives better accuracy than the other analytical methods. This is because the GLM considers the maintenance level of the component by discriminating between corrective and preventive.

In this Paper, We are going to propose the fire protection system with using CAN(Controller Area Network). The larger, higher and deeper buildings are, the more dangerous people are when fire happens. We are aware of the problems of prior Fire protection system. Therefore, we construct embedded system based on CAN communication that is capable of N:N communication, and build independent Fire protection system.

본 연구에서는 육군 지상전술 C4I체계(ATCIS)의 전력화 초기단계에서 주요국가의 C4I 체계와 한국의 체계에 대한 특성을 살펴보았으며, 또한 정책이나 기술적인 분석에서 한 단계 더 나아가 이론적 배경과 더불어 운용과 사용자 요구와 관련된 자료를 수집하여 분석을 실시하였다. 따라서 운용자 요구 수준에 맞는 체계의 보완과 C4I체계의 디지털화 등 발전방안을 도출하였다.

Interface-engineered junctions with $YbBa_2$$Cu_3$$O_{7}$ as the counter electrode were demonstrated. The junctions exhibited excellent Josephson characteristics with a Josephson critical current ($I_{c}$) ranging from 0.1 mA to 8 mA and a magnetic field modulation of the $I_{c}$ exceeding 80% at 4.2 K while maintaining complete c-axis orientation of the counter-electrode layer. The$ 1\sigma$ spreads in $I_{c}$ for junctions with an average $I_{c}$ of 1-2 mA were 5-8% for 16 junctions within a chip, and 9.3% for a 100-junction array. Our dI/dV measurements suggest that a theoretical approach taking into account both a highly transparent barrier and the proximity effect is required to fully understand the Junction characteristics.ristics.

소나무 단일개체에서 채취한 풍매종자 중 임의로 선택한 96개의 반수체 genome을 이용하여 RAPD 및 I-SSR PCR 증폭산물을 분석하였다. RAPD 분석용 primer 200개와 I-SSR 분석 용 primer 90개를 screen하여 증폭산물의 분획양상이 선명한 RAPD primer 45개와 I-SSR primer 22개를 선택하여 PCR을 수행하였다. 45개의 RAPD primer중 25개와 22개의 I-SSR primer중 18개를 사용한 PCR 분석결과에서 멘델의 유전양식을 만족하는 52개 (2.08/primer)와 46개 (2.56/primer)의 다형성 유전자좌를 각각 확인하였다. 멘델의 유전양식을 만족하는 96개의 다형성 유전자좌를 대상으로 LOD 3.0에서 two-point 연관분석을 수행한 결과 총 63개(35개의 RAPD와 26개의 I-SSR)의 유전자화가 20개의 연관군에 속하는 것이 확인되었다. 총 연관거리는 1097.8 cM이었으며, 유전자좌간 평균연관 거리는 25.5 cM, 최소 및 최대연관 거리는 각각 4.3 cM 및 54.9 cM이었다. 그리고 20개의 연관군 중 14개의 연관군이 RAPD와 I-SSR 유전자좌의 통합에 의해서 형성된 연관군이었다. 즉, 52개의 RAPD와 46개의 I-SSR 유전자좌를 각각 분석한 결과보다 길고 새로운 연관군이 형성되었다. 보다 정밀한 유전자 연관지도를 작성하기 위해서는 보다 많은 수의 DNA marker가 필요하다고 판단되며, 본 연구의 결과는 소나무의 유용 유전자의 확인 및 생장과 재질과 같은 유용형질에 대한 QTL의 위치를 결정하는 데 기초자료가 될 것이다.
