Many Companies have expected that BPR and ERP implementation could keep up with changes in business management and information technology in Mega-competition era. But we cannot expect the performance improvement of enterprises without conjunction of BPR and ERP implementation This paper points out the problems of BPR ＆ ERP implementation and present solutions to problems by the BPR using ERP system and the concurrent implementation of BPR and ERP.

The management science was concerned about how to use the main point of the management science model and it's technique by the rational primary factors. The problem's definition, estabilished of the model and it's solving. These function are very difficult and important problems, what is more important, are the model of management science's real prosecution to the manager and management scientist. The management science give us a clue to the solution of a business problem. To get needs conclusion and achieving the estabilished object, we must implement a plan, a stratgem, a policy. If we were not implementing the recommended items, we may call the estabilished model and problem solving impractical, ivory-tower theorizing. But, the implementation of management science model is a complicated problem that is involved mutual relations of managers and management scientist, linkage parts member and the resources of organization. And the other problems of implementation are very complicated problems composed of technologic and economic, social and politic, psychological. This paper reports the implementation of a success that possibly studies a fluent and a chief cause to systematic analysis. Then, first of all I will define of implementation and from these, construction of a unity system, I continue with a catch hold of a main point and a fluent for the successful implementation.

This study employs a case study method to examine the current implementation of student teaching program in a particular teacher education institution and its affiliated school. The purpose of this study is to improve the quality of home economics student teaching program by promoting collaboration of teacher education institution and host schools. Following five research problems are addressed : (1)Examining the problems of student teaching from the literature review ; (2)Identifying the problems of student teaching recognized by home economics student teachers ; (3)Identifying the problems of student teaching and plans for improvements suggested in the seminar held for home economics teacher ; (4)Analyzing and comparing the differences of opinion between home economics student teaching program ; and (5)Suggesting alternative implementation plans for improving student teaching program by promoting collaboration of teacher education institution and host schools.

We describe a parallel implementation of a relaxed Hermitian and skew-Hermitian splitting preconditioner for the numerical solution of saddle point problems arising from the steady incompressible Navier-Stokes equations. The equations are linearized by the Picard iteration and discretized with the finite element and finite difference schemes on two-dimensional and three-dimensional domains. We report strong scalability results for up to 32 cores.

The purpose of this study is to suggest a meaningful way of implementing science and engineering integrated lessons in school science settings. To this end, two types of science and engineering integrated lesson units (focusing on the physic concepts of light and wave) were developed based on the core elements of science and engineering integrated lesson; object, context, engineering design, and connection with science. These two units were implemented in free semester program in a middle school in a metropolitan city. Throughout the process of program implementation, instructor's reflection and focus group interview with participant students were collected to reveal problems arising from the field implementation. In addition, engineering education experts were interviewed to discuss the potential problems and possible solutions for the problems. As results of the study, five main problems of implementing escience and engineering integrated lessons in a school science setting were revealed and practical solutions for the problems were suggested by the experts.

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.

In this paper, design and implementation issues for a network-oriented RF emitter localization system with array antenna are discussed. For hardware, the problem of array mismatch and RF/IF channel mismatch are introduced and the calibration schemes for solving those problems are also provided. For software, it is explained how to overcome the drawback of conventional MUltiple Signal Identification and Classification (MUSIC) algorithm in a point of identifying the number of received signals and problems such as Data Association Problem and Ghost Node Problem in regard to multiple emitter localization are presented with some approaches for getting around those problems. Finally, for implementation, a criterion for arranging each of sensors and a requirement for alignment of array antenna' orientation are also given.

GIS의 실행에 있어서는 예상치 못했던 여러 문제점들이 나타나기 마련이고, 이러한 문제점들이 계속 무시된다면 GIS의 도입 및 실행이 더욱 어려워질 것이다. 이러한 문제점들을 해결하고 GIS의 실행을 효율적으로 진행시키기 위해서 다음과 같은 사항들이 요구된다. 첫째, GIS 중장기계획을 세우는데 있어서 한국지방정부들은 재정, 기술부문 뿐만 아니라 조직문화, 도입될 새로운 기술에 대한 직원들의 경험과 인식에 대하여 좀더 깊은 이해가 있어야 할 것이다. 둘째, 중복된 투자나 기술적인 문제들, 예를 들어 수치지도와 기존의 지적도와의 불일치, 제작기관이 다른 수치지도들의 불일치를 해결하기 위해서는 수치지도 제작에 있어서 표준화가 요구되며 각 기관과 부서들의 협력이 절대적으로 필요하다.

By managing not only geographical information but also various kinds of attribute data. GIS presents useful information for decision-makings. Most of decision-making problems using GIS can be formulated into network-optimization problems. In this study we deal with the implementation of network optimization system that extracts data from the database in GIS. solves a network optimization problem and present optimal solutions through GIS' graphical user interface. We design a nitwork optimization system and present some implementation techniques by showing a prototype of the network optimization system. Our network optimization system consists of three components : the interface module for user and GIS the basic network the program module the advanced network optimization program module. To handle large-scale networks the program module including various techniques for large sparse networks is also considered, For the implementation of the network optimization system we consider two approaches : the method using script languages supported by GIS and the method using client tools of GIS. Finally some execution results displayed by the prototype version of network optimization system are given.
