Pyrolysis system will plat a big role on the resource recovery of wastes without secondary pollution problems comparing usual incineration system. Pyrolysis experiments of municipal solid wastes was conducted and the results are as follows. 1) From tile compression test before the pyrolysis, moisture removal was observed from 70% compression and the variation of the removed moisture amount was detected until 80% compression. Over the 80% compression, there was no change. 2) Non-isothermal pyrolysis reaction constant was found out through the experiment. When the increasing rate of temperature varied from 20 to 40 K/min, the activation energy of cellulose and plastic were 100~160 KJ/mol and 192~239KJ/mo1, respectively. The order of reaction was on the range of 1.2~1.8. As the increasing rate of temperature increased, the activation energy was decreased.

In this paper, we propose a fast small target detection method using multiple filters, and describe system implementation using IPP libraries. To detect small targets in Infra-Red images, it is mandatory that you should apply a filter to eliminate a background and identify the target information. Moreover, by using a suitable algorithm for the environments and characteristics of the target, the filter must remove the background information while maintaining the target information as possible. For this reason, in the proposed method we have detected small targets by applying multi area(spatial) filters in a low luminous environment. In order to apply the multi spatial filters, the computation time can be increased exponentially in case of the sequential operation. To build this algorithm in real-time systems, we have applied IPP library to secure a software optimization and reduce the computation time. As a result of applying real environments, we have confirmed a detection rate more than 90%, also the computation time of the proposed algorithm have been improved about 90% than a typical sequential computation time.

Pyrimidine nucleosides fused with 3',4'-tetrahydrofuran ring were synthesized, starting from l,2;5,6-di-O-isopropylidene-D-glucose and assayed for antiviral activities. Thymine analogue I and its corresponding 2'-deoxy analogue 3 exhibited high cytotoxicity instead of giving antiviral activities.

Renal lymphangiectasia is a rare cystic kidney disorder. This disorder has been termed renal lymphangioma, renal lymphangiomatosis, pararenal lymphatic cyst. We report on a 32-year-old man admitted with complaints of abdominal discomfort, in whom unilateral renal lymphangiectasia with renal vein thrombosis was diagnosed. Abdominal computed tomography revealed left perirenal fluid collection with multiloculation. Left renal vein was completely obliterated due to thrombosis and inferior vena cava (IVC) was partially obliterated. Perirenal fluid collection and renal vein thrombosis were treated initially with percutaneous drainage and anticoagulation therapy. The biochemical features of the drained fluid were compatible with lymphatic fluid. Since there was no decrease in the amount of daily drainage, left nephrectomy and IVC thrombectomy was performed on the 34th day of hospitalization. Left kidney was enlarged (15×10×18 ㎝, 750 g) and composed of numerous smooth, thin-walled cysts. Pathologic diagnosis was renal lymphangiectasia.
