according to increase of vehicles and long length of tunnel load, ventilation of tunnel take a serious view. Purpose of tunnel ventilation is to secure driver's safety from contamination of CO, smoke etc.. by using ventilation Unit. In the meantime ,the contaminant discharge amount of vehicles reduce year by year because performance of a car improves. There is various way to do computation of jet fan. PIARC is way to produce ventilation amount in tunnel as that yield the discharge amount in number of model vehicles. It is true that when calculate number of jet fan of tunnel, PIARC depends on previous basis data in the vehicle‘s quantity of contamination. Therefore, This research apply to calculate number of jetfan by using statistics.

<P>An energy-efficient hardware architecture of complex-valued matrix lower-upper (LU) triangularization for multi-input-multi-output (MIMO) receivers is presented in this paper. In the LU triangularization process, Gaussian elimination operation is expressed as a series of vector-scalar products, where basic common computations can be precomputed and shared to reduce computational complexity. Our computation-sharing-based architecture was implemented using a 0.25-μm CMOS process, and the hardware can perform LU triangularization from 2 × 2 to 8 × 8 matrices. Numerical results show that the proposed architecture has considerable energy savings over conventional matrix triangularization schemes.</P>

Safety of recombinant porcine somatotropin administration on pig was studied using 32 Landrace x Yorkshire crossbred pigs. The starting body weight ranged from 55.5kg to 65.3kg. Eight pigs were allotted to each low dose group of sustained releasing rPST(SL), high dose group of sustained releasing rPST(SH), daily injection group of rPST(DI), and control group(C). Pigs in SL group and SH group were injected subcutaneously twice in 3 week-interval with 1000$\mu\textrm{g}$ and 2000$\mu\textrm{g}$ of sustained releasing rPST per kg body weight, respectively. Pigs in DI group were injected intramuscularly with 100$\mu\textrm{g}$ of rPST everyday for 6 weeks. Blood was collected from anterior vena cava just before the first treatment, and at four weeks and six weeks of experiment. Hematological parameters and blood chemical parameters indicating liver function, kidney function, electrolyte metabolism, mineral metabolism and lipid metabolism were determined. Necropsy and urinalysis were performed after final blood collection. The results were summarized as follows, and it is concluded that rPST administration does not affect pig health negatively. 1. rPST administration did not affect kidney function as manisfested by BUN, creatinine and urinalysis. 2. rPST administration did not affect liver function as manisfested by total protein, albumin, serum AST activity serum ALT activity serum ALP activity, serum LDH activity, serum GGT activity and serum SDH activity. 3. rPST administration did not affect skeletal muscle, cardiac muscle and brain as manifasted by serum AST activity and serum LDH activity. 4. rPST administration increased blood glucose level within normal range. 5. rPST administration did not affect lipid metabolism as manisfested by triglyceride, cholesterol, and phospholipid concentrati on. 6. rPst administration dia not affect mineral metabolism as manisfested by calcium, phosphorus, magnesium and iron concentration. 7. rPST administration did not affect electrolyte metabolism as manisfested by Na, K, chloride concentration. 8. rPST administration did not affect erythrocyte count, leukocyte count, thrombocyte count, and plasma fibrinogen level.
