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 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.

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.

A linkage map for Japanese red pine (Pinus densiflora) was constructed on the basis of two DNA marker systems of random amplified polymorphic DNAs (RAPDs) and inter-simple sequence repeats (I-SSR). Haploid genomic DNAs were extracted from megagametophyte tissues of 96 individual seeds in a single tree. A total of 98 DNA markers including 52 RAPD markers amplified by 25 primers and 46 I-SSR markers amplified by 18 primers were verified as Mendelian loci showing 1 : 1 segregation in 96 megagametophytes which were ${\chi}^2$-tested at 5% significance level. Of them, 63 segregating loci turned out to be linked into 20 linkage groups by the two-point analysis. However, 35 loci (17 RAPD and 18 I-SSR) of the 98 segregating loci did not coalesced into any linkage groups at a LOD of 3.0. The linked 63 loci were separated by an average distance of about 25.5 cM, which were spanned 1097.8 cM as a whole. The minimum and maximum map distances of the linkage groups were 4.3 cM and 54.9 cM, respectively. Incorporation of I-SSR loi into linkage map of RAPD loci resulted in extended and partially more saturated linkage blocks.
