The present study was undertaken in moist temperate forest of Mandal-Chopta area in the Garhwal region of Uttarakhand, India. The aim of the present study was to assess the physical properties of soils in relation to the forest structure and composition. Twelve forest types according to the altitude, slope aspect and species compositions were selected for the study. Physical properties of soil i.e., soil colour, soil texture (per cent of sand, silt and clay), moisture content, water holding capacity, porosity, bulk density (gm/$cm^3$) and void ratio were analyzed for three different depths viz., (i) 'upper' (0-10 cm), (ii) 'middle' (11-30 cm) and (iii) 'lower' (31-60 cm) in all the selected forest types. Phytosociological and diversity parameters viz. total basal cover ($Gha^{-1}$), stem density ($Nha^{-1}$), tree species richness, Simpson concentration of dominance and Shannon-Wiener diversity index were also calculated for each forest type. This study also provides the comparisons between the results of physical analysis of the present study with numerous other previous studies in the temperate Himalayan region of the Uttarakhand.

Spinosyns A and D are potent ingredient for insect control with exceptional safety to non-target organisms. It consists of a 21-carbon tetracyclic lactone with forosamine and tri-Omethylated rhamnose which are derived from S-adenosyl-methionine. Although previous studies have revealed the involvement of metK1 (S-adenosylmethionine synthetase), rmbA (glucose-1-phosphate thymidylyltransferase), and rmbB (TDP-D-glucose-4, 6-dehydratase) in the biosynthesis of spinosad, expression of these genes into rational screened Saccharopolyspora spinosa (S. spinosa MUV) has not been elucidated till date. In the present study, S. spinosa MUV was developed to utilize for metabolic engineering. The yield of spinosyns A and D in S. spinosa MUV was $244mgL^{-1}$ and $129mgL^{-1}$, which was 4.88-fold and 4.77-fold higher than that in the wild-type ($50mgL^{-1}$ and $27mgL^{-1}$), respectively. To achieve the better production; positive regulator metK1-sp, rmbA and rmbB genes from Streptomyces peucetius, were expressed and co-expressed in S. spinosa MUV under the control of strong $ermE^*$ promoter, using an integration vector pSET152 and expression vector pIBR25, respectively. Here-with, the genetically engineered strain of S. spinosa MUV, produce spinosyns A and D up to $372/217mgL^{-1}$ that is 7.44/8.03-fold greater than that of wild type. This result demonstrates the use of metabolic engineering on rationally developed high producing natural variants for the production.

MPEG(Motion Picture Expert Group)과 같은 멀티미디어 스트림은 연속적 재생으로 인해 데이터의 지속적인 디스크 검색을 요구한다. 따라서, 커널의 효율적인 지원이 필요한데, 유닉스 계열의 리눅스 버퍼 캐시 시스템은 비정기적이고 비실시간 데이터인 텍스트 데이터용으로 설계되었다. 대용량의 연속 미디어의 경우 커널 주소공간에서 사용자 주소공간으로의 대량의 복사가 이루어지므로 이 과정에서 CPU의 과중한 오버헤드가 발생한다. 이것은 시스템 처리율을 저하시킬 뿐만 아니라 QOS(Quality of Service)도 보장할 수 없다. 본 논문에서 이 메모리 복사 오버헤드를 감소시키기 위한 direct I/O와 one copy 기법을 리눅스 커널에서 설계 및 구현하였다. direct I/O는 디스크의 데이터를 커널 버퍼로 복사하지 않고 사용자 버퍼로 직접 복사하므로 CPU 오버헤드를 획기적으로 감소시킬 수 있다. 그리고, one-copy는 사용자 버퍼로 데이터를 복사하지 않고 직접 네트워크로 전송하는 기법이다. 구현 결과, CPU 오버헤드의 상당한 감소와 시스템의 처리율이 향상됨을 확인하였다.

Porcine reproductive and respiratory syndrome (PRRS) is characterized by reproductive failures in sows and respiratory problems in piglets. The nucleocapsid(N) protein, encoded by the open reading frame 7 (ORF7) gene, is known to be the most abundant and antigenic protein in PRRS virus. Therefore, it was suggested that the N protein could be a suitable candidate for the detection of PRRS virus-specific antibodies and diagnosis of PRRS. In the present study, the ORF7 gene encoding the N protein was cloned and expressed as a fusion protein with the glutathione S-transferase (GST) in Escherichia coli. The resulting GST-N recombinant protein was used as an antigen for an indirect sandwich enzyme-linked immunosorbent assay (i-ELISA). Expressed GST-N recombinant protein was migrated at 41 kDa and reacted with ORF7-specific monoclonal antibody by Western blotting. In order to increase the specificity of the ELISA for the detection of PRRS virus-specific antibodes, an i-ELISA was developed using an anti-GST antibody as a capture antibody. The sensitivity and specificity of developed i-ELISA were 92% and 96%, respectively. Based on these results, it was suggested that the i-ELISA is a simple and rapid test for screening a large number of swine sera for the anti-PRRS virus antibodies.

The natural plants were screened for new cosmetic materials. Many parts of Nelumbo nucifera has been investigated for anti-wrinkling and anti-furrowing effects. The leaves. flowers and stamens of Nelumbo nucifera were extracted with ethanol or distilled water. The effects of cell viability and $H_2O_2-induced$ cytotoxicity were studied on CCD-986sk human fibroblast cell line by MTT assay. We measured various effects related to skin such as the synthesis of MMP-1 and type I procollagen. The ethanol extract of Nelumbo nucifera leaves (ENL) at concentrations of 30 ${\mu}g/ml$ showed maximum cell viability on CCD-986sk cells by 129.70%. and $H_2O_2-induced$ cytotoxicity was blocked by ENL (5. 10. 20. 30. and 40 ${\mu}g/ml$) concentration-dependently. The synthesis of MMP-1 and type I procollagen were positive in ENL. These results suggest that ENL has anti-oxidant and anti-furrowing effects.
