  • Co-firing incompatibility between the low temperature sinterable Glass/ceramic and Ag-thick film was studied. The dielectric material, which has been developed for microwave frequency applications, consists of $SiO_2-TiO_2-Bi_2O_3$-$Bi_2O_3$-RO system(RO:BaO -CaO-SrO) crystallizable glass and $Al_2O_3$as a ceramic filler. The large camber in the sintered specimen and cracks at the Ag-film under the influence of the camber occurred due to the difference of densification rate between the ceramic sheet and the Ag-film $B_2O_3$addition to the Glass/ceramic mixture reduced the severe camber. The cambers decreased with increasing the $B_2O_3$ content, and completely disappeared with 14 vol% $B_2O_3$addition. With additions of $B_2O_3$, $\varepsilon_{r}$ decreased abruptly, Q$\times$f value increased largely and the $\tau_f$ value of the material quickly shifted to positive one.

  • To elucidate the mechanism underlying the regulation of hST8Sia I gene expression in FenR-induced SH-SY5Y cells, we characterized the promoter region of the hST8Sia I gene. Functional analysis of the 5'-flanking region of the hST8Sia I gene showed that the -1146 to -646 region functions as the FenR-inducible promoter of hST8Sia I in SH-SY5Y cells. Site-directed mutagenesis indicated that the NF-&B binding site at -731 to -722 was crucial for the FenR-induced expression of hST8Sia I in SH-SY5Y cells. To investigate which signal transduction pathway was involved in FenR-stimulated induction of hST8Sia I in SH-SY5Y cells, we performed Western blot analysis using phospho-specific antibodies in order to measure their degree of regulatory phosphorylation. Phosphorylations of AKT and RelA (p65) subunit of NF-${\kappa}B$ were significantly elevated in cytosolic and nuclear fractions of FenR-stimulated SH-SY5Y cells, respectively, than in control or DMSO-treated SH-SY5Y cells. These results suggest that FenR induce transcriptional up-regulation of hST8Sia I gene expression through translocation of RelA (p65) subunit of NF-${\kappa}B$ to nucleus by AKT signal pathway in SH-SY5Y cells.

  • A content based pub/sub (Publish/subscribe) services at the peer-to-peer network has the requirements about how to distribute contents information of subscriber and to delivery the events efficiently. For satisfying the requirements, a DHT(Distributed Hash Table) based pub/sub overlay networking and tree type topology based network construction using filter technique have been proposed. The DHT based technique is suitable for topic based pub/sub service but it's not good contents based service that has the variable requirements. And also filter based tree topology networking is not efficient at the environment where the user requirements are distributed. In this paper we propose the R-Tree algorithm based pub/sub overlay network construction method. The proposed scheme provides cost effective event delivery method by mapping user requirement to multi-dimension and hierarchical grouping of the requirements. It is verified by simulation at the variable environment of user requirements and events.

  • This paper presents the results of research on developing marine unified communications to provide VoIP service based on marine satellites. With the recent popularity of smart-phones and other mobile devices, the demand for Internet-based wired and wireless unified technology has been growing in marine environments, and increasing interest is being directed to VoIP products and service models with high price competitiveness and the ability to deliver a variety of services. In this regard, this research designed three instruments, developed their unit modules, and verified their performances. These three instruments included the following: (1) a marine VoIP module equipped with an analogue gateway that can be linked to the existing devices used in vessels, which is more than 80% smaller than that of a land system; (2) a text/voice/video engine for marine satellite communications that runs on technology that minimizes communication data usage, which is a core technology for a marine VoIP service; and (3) a unified communication service that can support multilateral cloud-based message conversations, telephone number-based call functions, and voice/video calling between a private space in a ship and shore.

  • In this study, patterns of proteome expression were monitored and specifically expressed proteins in human milk were detected in collected human milk after 1 week, 3 weeks, and 6 weeks from delivery. A quantitative shotgun proteomic approach was used to identify human milk proteins and reveal their relative expression amounts. For each sample, two independent human milk samples from two mothers were pooled, and then three replicated shotgun proteomic analyses were carried out. Casein, which is a highly abundant protein in human milk, was removed, and then trypsin was treated to produce a digested peptide mixture. The peptides were loaded in the home-made reversed-phase C18 fused-silica capillary column, and then the eluted peptides were analyzed by using a linear ion-trap mass spectrometer. The relative quantitation of proteins was performed by the normalized spectral count method. For each sample, 81-109 non-redundant proteins were identified. The identified proteins consisted of glycoproteins, metabolic enzyme, and chaperon enzymes such as lactoferrin, carboxylic ester hydrolase, and clusterin. The comparative analysis for the 63 proteins, which were reproducibly identified in all three replications, revealed that 25 proteins were statically significant differentially expressed. Among the differentially expressed proteins, Ig lambda-7 chain C region and tenascin drastically decreased with the delivery time.

  • This study was carried out to propose improvement planting method by the research and analysis of planting concept, planting density, planting style and pattern in apartment complex, Seoul. Survey sites were selected by reflecting the change of green area ratio : Hawgok Jugong apartment complex, Gangseo-gu(1974), Samik-green apartment complex, Gangdong-gu(1980), Dongsindaea apartment complex, Gangseo-gu(1992). Green area in apartment complex was classified with front green area, side green area, and back-side green area. Planting concept that composed of landscape planting concept but anyother concept was not, was similar to all sites not differ from creation time. And planted species was not differ from planting style. Planting density was of both conopyㆍunder story layer was 0.0∼0.2 tree/$m^2$, and that of shrub layer was 0.0∼0.5 tree/$m^2$ Shrub layer planting density was insufficient and the density was not changed according to the creation time. Canopyㆍunderstory and shrub was planted to another green space, not concern with multi-layer structure. Planting pattern was utilized to single planting, linear planting, and random triangle planting, but it was not to the change that in each green space planting concept. Green area in apartment complex should be variety according to planting density, planting structure and planting pattern. And we should get the function of covering and beauty in case of front green space, that of ecological environment and increasing green volume in case of back-side green area, that of increasing green volume in case of side green area, apartment complex.

  • The project management information system (PMIS) has recently been developed by using the information technology(IT) in order to implement advanced information management technology to construction industry in Korea. The PMIS has been applied not only to domestic construction projects, but also to some overseas projects executed by Korean construction companies. This study was performed to develop the PMIS that is tailored to the US construction IT market. It has been monopolized by the US-based IT companies, but other companies are recently emerging with competitive technology and market strategy. As a preceding study, existing commercially available systems were analyzed, and the required features of the PMIS were identified by analyzing the core elements of contract, process and cost management about construction projects in the US. Then, the PMIS was developed based on the aforementioned analysis results. The system includes the document management module with an internal electronic approval system, the cost-plus-based automatic labor cost calculation module, and the progress management module to support the integrated project cost management. In addition, the functionality of the developed system was verified by experts about construction management in the US via questionnaire survey. The developed PMIS, in this study, is expected to be applied not only to the US construction IT market as a system specialized for the US construction industry, but also to other oversea markets in the future.

  • The proximities of Cheonggye creek was a maj or space for the gathering of large populations from the past times and it is also a place containing the joy, anger, sorrow, pleasure and lives of the citizens. The Cheonggye creek which flowed downtown of Seoul throughout many historical events had disappeared into history completely in the modernization process due to the contamination with life sewages and overflow. However, the city authority of Seoul decided to restore it to its shape before covering the creek by means of dismantling the old elevated ways in Cheonggye creek in line with the Large Scale City Movement Project to revive the grey city and to improve the quality of the city landscape in 2002. The cultural space was created by activating the old town sphere in Cheonggye Creek and the amenities of the giant city was improved by the cultural and natural wave created along the creek. In addition, the educational opportunity has been provided to the citizens by means of reviving its historical nature. The design and cultural value of the Cheonggye Plaza were restored for the mean time and the urban environment requested during modem times was established. The Cheonggye Plaza which heightened the balanced development in Seoul which has been developed in an unbalanced way by dividing into northern and southern area of the river is very meaningful in the viewpoint of the landscape architect who designs the urban space. The re-birth as a cultural space of downtown owing to the efforts of the said cultural catalysts is meaningful.

  • This paper critically studies Meidner's wage-earner funds project. On the basis of this, this paper intends to create new prospects for a universal welfare regime. From the perspective of the welfare system, the funds project is a correction or supplement of the Swedish welfare system of the Swedish model centered on 'redistribution'. However, the funds project shares the ideology of Swedish model and its fundamental premise, I.e. guild socialism and labor-centrism. This paper discusses the limitations of the funds project resulting from this, especially with regard to its three purposes: equalization of property distribution, economic democracy and the correction of excess profit. It then highlights that the alternative to overcome the limitations of the funds project and the Swedish universal welfare system should be based on a new ideology and fundamental premise that is cut off from guild socialism and labor centrism. As an alternative fulfilling this, this paper focuses on theories that suggest that the Common Wealth Fund should be created and basic income should be implemented in the form of dividends as its dividend. As a result, Commons Capital Stock and the basic income as its dividend are presented as alternative prospects for the funds project.
