Background : In recent years, gonorrhea has been panedemic and remains one of the most commom STDs in the world, especially in developing countries. Objective & Methods: For the detection of a more effective therapeutic regimen and assessing the prevalence of PPNG, we have been trying to study the patients who have visited the VD Clinic of Choong-Ku Public Health Center in Seoul since 1980 by means of the chromogenic cephalosporin method. Results: In 1996, 139 strains of N. gonorrhoeae were isolated, among which 53(39.0%) were PPNG. Conclusion: Our results suggests that after a peak of 74.3% in 1993, the prevalence of PPNG in Seoul is gradually declining.

The web 2.0 is leading a rapid change of internet services. The UCC(User Created Contents) service is one of the representative internet services with web 2.0 paradigm. in this paper, we design and implement the UCC services prototype system for image and video. The proposed system does not need to install ActiveX and client programs on devices of users to edit their contents. All processes for editing UCC are conducted on the server. Our proposed system consists of the two components such as the multimedia editing subsystem and the metαdαtα management system. They provide the API to UCC service developers or vendors. The multimedia editing subsystem supports editing for image and video. and the streaming services of video. The metαdαtα management subsystem supports the metαdαtα management and retrieval of image and video.

<P><B>Objectives</B></P><P>To explore options of cell sources for regeneration of cartilage, turbinate fibroblasts were tested for their differentiation potential when cultured in three-dimensional scaffolds with growth factors and co-cultured with septal chondrocytes.</P><P><B>Methods</B></P><P>Fibroblasts and chondrocytes were seeded on to an alginate sponge in different proportions and were stimulated with TGF-β1 and IGF-I. Chondrogenic differentiation of fibroblasts was assessed by histology including immunohistochemical staining, which was examined by reverse transcriptase polymerase chain reaction (RT-PCR).</P><P><B>Results</B></P><P>Chondroid cells with extracellular matrices occupied the porous structures of alginate sponge and immunolocalizations for type II collagen became prominent at four weeks in culture. Expression of type II collagen and aggrecan mRNA were detected by RT-PCR. Co-culture of fibroblasts and chondrocytes showed comparable expansion of cells and extracellular matrix to culture of chondrocytes only.</P><P><B>Conclusion</B></P><P>These findings suggest that human turbinate fibroblasts are apparently redirected toward chondrogenic phenotype by in vitro culture system under specific conditions. Co-culture of turbinate fibroblasts with septal chondrocytes would be an effective method to expand cartilage specific extracellular matrix.</P>
