In this paper, we build a web ERP system that is focused on the logistics, storage, materials management to establish internal enterprise information system for small business. This system is possible to be transformed to separated modules so it is possible to be modified and added easily. And it is also implemented to provide mobile interlace for mobility extension. The ShopE.R ERP system is a solution that can be reorganized flexibly according to variable changes in the corporate business processes.

We constructed four recombinant plasm ids to enhance the production of clavulanic acid (CA) in Streptomyces clavuligerus NRRL3585: (1) pIBRHL1, which includes ccaR, a pathway-specific regulatory gene involved in cephamycin C and CA biosynthesis; (2) pIBRHL2, containing claR, again a regulatory gene, which controls the late steps of CA biosynthesis; (3) pGIBR containing afsR-p, a global regulatory gene from Streptomyces peucetius; and (4) pKS, which harbors all of the genes (ccaR/ claR/ afsR-p). The plasmids were expressed in S. clavuligerus NRRL3585 along with the $ermE^*$ promoter. All of them enhanced the production of CA; 2.5-fold overproduction for pIBRHL1, 1.5-fold for pIBRHL2, 1.6-fold for pGIBR, and 1.5-fold for pKS compared to the wild type.

A cluster of genes for ribostamycin (Rbm) biosynthesis was isolated from Streptomyces ribosidificus ATCC 21294. Sequencing of 31.892 kb of the genomic DNA of S. ribosidificus revealed 26 open reading frames (ORFs) encoding putative Rbm biosynthetic genes as well as resistance and other genes. One of ten putative Rbm biosynthetic genes, rbmA, was expressed in S. lividans TK24, and shown to encode 2-deoxy-scyllo-inosose (DOI) synthase. Acetylation of various aminoglycoside-aminocyclitol (AmAcs) by RbmI confirmed it to be an aminoglycoside 3-N-acetyltransferase. Comparison of the genetic control of ribostamycin and butirosin biosynthesis pointed to a common biosynthetic route for these compounds, despite the considerable differences between them in genetic organization.

기존 논문에서 CCD 카메라를 이용해 3차원 데이터를 획득하는 시스템을 소개했었다. 하지만, 정확도에서는 기존에 개발한 다른 PSD카메라를 이용한 시스템과 큰 차이를 보이지 않았다. 본 논문에서는 정확도를 개선하기 위한 여러 가지 실험을 했으며, 결과를 통해 상당히 향상되었음을 알 수 있다. 제안된 방법은 왜곡제거, z축 보정 등이며, 각 방법의 비교실험을 통해 얼마나 개선되었는지 살펴본다.
