  • We analyze the error in the p version of the of the finite element method when the effect of the quadrature error is taken in the load vector. We briefly study some results on the $H^{1}$ norm error and present some new results for the error in the $L^{2}$ norm. We inves-tigate the quadrature error due to the numerical integration of the right hand side We present theoretical and computational examples showing the sharpness of our results.

  • Effective use of debugging in computer science education is a topic that has received little attention. Existing tools either are too overwhelming for the novice or are too basic and inflexible. Furthermore, the integration of the debugger into complex IDEs have unfamiliar debuggers from students, resulting in a harmful proliferation of console I/O. In this paper, a new stand-alone educational debugging tool is presented, with simple but powerful tools for easily observing and modifying program execution state. This tool is analyzed from an user perspective, and is compared with existing tools.

  • This paper describes a new mechanism of detecting object of interest from a noisy image, without using any a-priori knowledge about the target. It employs a parallel set of filters inspired upon biological findings of mammalian vision. In our proposed system, several basic features are extracted directly from original input visual stimuli, and these features are integrated based on their local competitive relations and statistical information. Through integration process, unnecessary features for detecting the target are spontaneously decreased, while useful features are enhanced. Experiments have been performed on a set of computer generated and real images corrupted with noise.

  • In the present paper we first establish some basic results for a substantially more general class of functions defined below. The results include simple differentiation and fractional calculus operators(integration and differentiation of arbitrary orders) for this class of functions. These results are then invoked in determining similar properties for the generalized Wright's hypergeometric functions. Further, norm estimate of a certain class of integral operators whose kernel involves the generalized Wright's hypergeometric function, and its composition(and other related properties) with the fractional calculus operators are also investigated.

  • This study aims both to find the desirable orientation of the home management which have been often discussed in the academy of the home management since 1970's and to present a curriculum as a practical way of solving the problem of orientation. We conclude that the problems of the orientation have due partly to unprofessionalized mixture of sub-areas in the home management and partly to narrowed specialization in each sub-area. We suggest that the problems can be solved when 'family lives' is the main object of the home management and when the home management is approached on the viewpoint of 'integration' rather than 'specialization' The curriculum based on the analysis is consisted of 4 spheres; 1) basic subjects of family lives ) basic concepts and theories 3) subjects for Korean family lives 4) subjects for family counseling and policy.

  • Nude mice (BALB/c) were grafted with human 293 cells and PERV (porcine endogenous retrovirus)-IRES-EGFP (a packageable retroviral vector plasmid containing an internal ribosome entry site-enhanced green fluorescent protein)-producing pig PK15 cells in order to determine whether the pig cells could transmit PERV-IRES-EGFP to mice and human 293 cells in vivo. None of the transplanted human 293 cell lines were infected by PERV, but PCR analysis identified PERV-B provirus integration into both the heart and salivary gland of the inoculated nude mice. Our data indicate that hearts and salivary glands can be used to identify PERV-B receptors.

  • Before an actual military communications satellite is designed and constructed, a feasibility study should take place. The basic functions of such system can be observed and demonstrated in an X-Band payload simulator. For this purpose a Payload Concept Model (PCM) for X-Band payload subsystem has been developed to simulate the workings of an actual military communications payload. This paper explains and illustrates the mechanical design, manufacture, and integration of the PCM. Basic RF tests also have been performed in order to verify the design requirement of the system. The results demonstrate successful development of the PCM and operation without RF losses.

  • In this paper, we propose a multi-layered architecture of workflow management systems based on CORBA (Common Object Request Broker Architecture). The system aims to support product development processes in distributed environment. Many companies have started to adopt workflow management systems to manage and support their business processes. However, there are many problems in direct application of those systems to product development environments. These mainly resulted from the dynamic features of product development processes. It is strongly required to support dynamic processes as well as static and procedural ones in an integrated and consistent manner. To meet these requirements, a basic workflow management system has been developed as the core component of the integrated architecture. This performs the basic functions of workflow management system. Second, a dynamic workflow management system based on a bidding mechanism has been developed to manage processes that cannot be easily defined or are likely to be modified, Finally, an SGML workflow management system, which is the third layer in the architecture, has been developed to manage documents processing workflows by integration SGML documents contents and process information into the structured SGML document.

  • Developing tailor made Multimedia courseware ensuring effective implementation of instruction strategies is a challenge that manifests in myriad problems of software design and coding. In this paper an attempt has been made to analyse and identify coding and implementation problems, in the backdrop of using two different multimedia software development tools i.e. Visual Basic and Toolbook, which underpin the development and effectiveness of use of multimedia courseware. Solutions to such problems have been discussed in context of Tool book. The examples presented in this paper are based on the experience of designing and implementation of two large scale professional quality Multimedia courseware development projects.

  • Purpose: The purpose of this study was to develop and apply a simulation-problem based learning(S-PBL) package in basic life support(BLS). Methods: This study was used to developed BLS' S-PBL package throughout 12 steps of PBL package development model. Then, BLS' S-PBL methodology was implemented in second year student in the undergraduate emergency medical technology, and survey was done. Results: 1. S-PBL package model was presented based on conceptual model II of PBL ; PEL for professional action. 2. Quantitative analysis of survey was to the effectiveness of learning, 3.59 points ; 4.15 of BLS and 3.84 of integration and practical use of knowledge. 3. As to the satisfaction of student, S-PBL package management, tutor and self-satisfaction' score was 3.59, 3.82, 3.39 respectively. Conclusion: This study was suggested that S-PBL education would be necessary with improved tutor skill and achieved advantage of simulation and PBL.
