  • To support business service interoperability, it is necessary to extend WSDL and develop Business Service Document(BSD) to contain various business service informations. W3C delegates extension of WSDL to the user groups for their usages and objectives. Therefore this article defines BSD, which is extended version of WSDL. This article also presents Business Web Service Framework(BWSF), which supports business service interoperability and uses BSD. BSD Creator is developed to create correct, valid and well-formed BSD which is core component of BWSF. This article is expected to be used as base concepts for industrial adoption of business service interoperability architecture, and it is also expected to contribute for revitalize business service interoperability.

  • Failures of super large projects like IT Upgrade of Shinhan Financial Group can be a heavy blow not only to the company but even to the national economy. Research on the practices of risk management in those projects will provide invaluable lessons, enhancing capabilities and chances of successfully executing mission critical projects of the companies and the national economy as a whole. This paper analyzes the risk management of the Core Systems Reconstruction which was the most critical component of IT Upgrade. The analysis covers risk management plans, and identification and evolution, and control and monitoring of risk factors. This study confirms the major results of previous research on risk management in Korea. However, the analysis found as well some discrepancies of practices from the previous research results. This research also tracked the trajectories of evolution of risk factors and management. In particular, in depth analysis of control and monitoring is the first research in Korea on the "management" of risks in IT projects. The result of this research is expected to be a useful guide for theory development and practices of risk management in the future.

  • As a core component of a hydropower station, hydro turbines play a vital role in the integration of a power station. Research on the technology of hydro turbine is continuously increasing with the development of water electricity. On the basis of one-dimensional loss analysis, for three-dimension design, there are a lot of dimension of the internal flow passage shapes that are determined by experience. Therefore, the effect of the internal flow passage shapes on the performance and internal flow characteristics of a Francis hydro turbine model is investigated in this study. In this study, the small curvature of runner blade trailing edge shape is good for improving the efficiency of Francis turbine. The straight stay vane leading edge is good for suppressing the secondary flow. Moreover, suitable tongue passage shape and stay vane number improve the performance of the turbine considerably.

  • In order to build a conceptual design program for a liquid rocket engine system, performance based sub-programs for each core component of the engine system were made. Parts included were the combustion chamber, supersonic nozzle, centrifugal pump, and impulsive turbine. Simple mathematical models based on classical thermodynamic and inviscid theories were adopted with proper tuning by empirical data. In Part I, aiming to validate each sub-program, we examined the results of each program qualitatively, and parametrically investigated the sensitivity due to the change in design parameters.

  • EPCIS(EPC Information Services) system is a core component of EPCglobal Architecture Framework offering information of the freights, the time of awareness and the location of awareness on the EPCglobal Network. The role of EPCIS is to exchange information based on EPC. There are four kinds of event data which are object event data, aggregation event data, quantity event data, and transaction event data. These EPCIS events data are stored and managed in EPCIS repository. This study suggest the quantitative modeling about total number of EPCIS event data under the assumption to aware the RFID tags of items, cases(boxes), vehicles(carriers, forklifts, auto guided vehicles, rolltainers) at a time on the reading points. We also estimate the number of created EPCIS event data by the suggested quantitative modeling under scenario of process in the integrated logistics center based on RFID system And this study compare the TO-BE model with the AS-IS model about the total sizes of created EPCIS event data using the simulation, in which we suggested the TO-BE model as the development of the repository by skipping the overlapped records.

  • The psbC gene, encoding the intrinsic chlorophyll-binding protein of CP43, one of the PS core complex polypeptides, was cloned from the Panax ginseng chloroplast, which is composed of 1,422 nucleotides and the overall nucleotide sequence shows more than 84% identity to those of eukaryotic photosynthetic organisms. The predicted topology of CP43, based on hydropathy analysis, includes six membrane-spanning ${\alpha}-helices$ resulting in three lumenal and four stromal loops. The putative translation start codon for the psbC gene is located at 48 nucleotides upstream from the stop codon of the psbD gene whose product is also a component of the PSII reaction center, implying that the promoter of the psbC gene is possibly located in the middle of the structural gene of the psbD gene. Northern blot analysis of the in vivo accumulation of the psbC transcript from the plants grown under the various growth light intensities (5%, 10%, 20%, and 100%) of daylight indicated that the steady-state level of the psbC transcript was not significantly affected by light intensity.

  • We report molecular line observations of CO(1-0), $^{13}CO(1-0)$, CS(2-1), and HCN(1-0) with SRAO 6m telescope toward L1014-IRS which is thought to be a very faint infrared source embedded in previously known 'starless' core L1014. The CO(1-0) observations find several components with different velocities along the line of sight of L1014, $4km\;s^{-1}$ and between $40{\sim}50km\;s^{-1}$. We find a parsec scale CO molecular outflow at the $4km\;s^{-1}$ component for the first time the direction of which is coincident with that of the small scale (${\sim}500pc$) outflow previously found. Although the observation is not covered for whole area of the outflow, the size of the molecular outflow seems not very inconsistent with the expected age of L1014-IRS. More accurate size and shape of the molecular outflow from L1014-IRS will be determined from the full coverage mapping in CO over the outflow region in very near future.

  • Purpose: The purpose of this study was to explore the main prerequisite for Korean Advance Directives [KAD] to ensure their better use. Methods: Data were collected from two focus group interviews and individual email responses. Study participants were 5 doctors and 6 nurses. All interview data were transcribed and analyzed using qualitative content analysis. Results: Three main themes emerged; establishing a philosophy of KAD, protocol to practice KAD, and the KAD document itself. A philosophy is needed to ensure individual needs, consensus to practice AD and identify principle agents. The core of protocol was found to be as follows; 1) process, 2) premise, 3) procedure, 4) contextual preparation, 5) timing, 6) feasibility. Component and feasibility need to be established for the document itself. Conclusion: For a positive acceptance of KAD in Korean society, a culture sensitive, reality based, and user friendly AD needs to be developed.
