  • To solve the problem of low inter-operability of systems and low reusability caused by not being standardized and common-shared development foundation between software developers, the government has proposed e-Government(eGov) standard framework. However, the development method based on eGov standard framework is not easy to learn and to use fluently, because it is so dissimilar the existing traditional development method. In this paper, we propose an approach for developing web applications by reusing common components of eGov standard framework, and describe about the case study of developing Can_Pro(Computer Aided Nutritional analysis program for Professionals) based on eGov standard framework. Consequently, we show improvement in productivity and reduction budget through reusability of common components and eGov standard framework.

  • In order to reduce a product life cycle and to improve productivity, it is required to automate the design/analysis processes. In general, since the design/analysis processes need a lot of time and resources, the various engineering resources should be integrated and utilized effectively in the distributed environments. KIMM (Korea Institute of Machinery and Materials) constructed the SOA-based e-Engineering framework to automate the execution of the design/analysis processes and to integrate the engineering resources in the distributed environments. This paper presents the concepts and the structures of the e-Engineering framework. Also it classifies the exceptional cases that will be able to occur in the e-Engineering framework and suggests the recovery techniques from the exceptional cases with viewpoints of the engineering process and the task, respectively.

  • 네트워크 서비스에 있어서 품질을 정확히 측정하고 품질지수를 도출하는 것은 매우 중요하다. 종래의 네트워크 서비스에 대한 품질지수는 QoS(Quality of Service)로서 많은 연구가 있어왔다. 하지만 QosS를 통한 사용자 품질지수는 실제 사용자의 서비스 만족도를 효과적으로 표현해 주지 못하였다. 그래서 본 연구에서는 QoE(Quality of Experience)라는 개념을 도입하여, 사용자가 실제로 느낀 서비스의 만족도를 도출하고자 하였다. 사용자의 서비스 만족도를 잘 표현해주는 QoE를 도출하기 위하여 본 연구에서는 QoE Framework를 제안한다. QoE Framework는 framework를 위해 동작하는 agent들로 구성된다. QoE Framework의 agent는 크게 서비스 제공자측과 서비스 사용자 측으로 나눌 수 있는데, 서비스 사용자 측의 agent는 서비스를 이용하다가 사용자가 서비스 불만족을 감지하였을 때, 서비스 제공자측 agent는 사용자측 agent로부터 받은 서비스 불만족에 대한 feedback으로부터 QoE도출 알고리즘을 사용하여 최적의 QoE를 도출하는 기능을 한다. 서비스 제공자측 agent의 QoE도출 알고리즘으로 GA(Genetic Algorithm)을 사용하여 최적의 값을 구하게 된다. QoE framework의 알고리즘에서는 불만족 feedbaek을 이루는 QoS 파라미터들간의 중요도와 관계를 도출하여, 주어진 서비스 개선 비용으로 최적의 QoE를 도출함으로써, 네트워크 서비스에 대한 사용자의 만족도를 최대로 높이는 결과를 도출하게 된다.

  • An e-catalog system provides whole product data and services by publishing newly updated information that connects PDM systems in an enterprise. With its capability to connect customers, suppliers, producers, distributors and downstream manufacturing activities, the e-catalog system can be applied to integrate e-business and provide immense business opportunities. In this paper we propose a framework focusing on constructing an efficient e-catalog system that can be used for online mass customization. The effectiveness of the proposed framework is validated with experimental results.

  • This paper describes an e-Engineering framework to support collaborative design of automotive suspension systems developed at KIMM(Korea Institute of Machinery and Materials). The e-Engineering framework is proposed and developed on the base of the multi-layered software agents including engineering task agent which is generated from the domain knowledge of experts. The developed framework is aim to widely spread application to the small and medium enterprises by adopting open source technologies such as JADE (Java Agent Development Framework) and by using the independent characteristics related with applicant H/W and 81W system. This framework can provide an integrated design environment to support distributed personnel, design activities and engineering resources during product development process. For the validation of the system's applicability and efficiency, the several practical design processes for automotive suspension systems of RR/FR lower arms and RR cross member are applied and discussed.

  • The Quality of Experience (QoE) of next Generation wired/wireless network services based upon IP networking is becoming a popular issue in recent years. The user experience of Internet services such as IPTV, online game, web surfing and etc, are becoming the most desirable factors to service providers to improve service performance and customer's satisfaction. However, collecting user experience from customers and obtaining the QoE parameters from the Quality of Service (QoS) parameters such as bandwidth, delay, jitter or admission control algorithm, are difficult subjects because of the various service types and user characteristics. In this paper, we propose a framework which contains service classification, QoE analysis and service enhancement steps for a suitable QoE measurement and management protocol. We define the user satisfaction indicators of the Internet services, classify the categories of each type of services, and analyse the Key Performance Indicator (KPI) in each type of services to perform the QoS parameters and improving the service qualities.

  • A product family design has received much attention over the last several decades, since a product family-based development shortens lead-times and reduces cost, as well as increases efficiency and effectiveness of the product realization process. It is challenging work, however, to define the product family design in the heterogeneous product development environments, due to myriads of products related information described in different ways across products in any companies. In this paper, we provided a way of defining product family design framework using formal concept analysis and ontology language. Based on this, the specific product family can be derived by ontological reasoning, and the new product concept can be also expanded in the framework. The proposed framework is formalized using OWL (Web Ontology Language) and implemented in $Prot{\acute{e}}g{\acute{e}}$. Actual product family design algorithm is carried out using FaCT++ engine, a plug-in to $Prot{\acute{e}}g{\acute{e}}$, and the benefits of the proposed method are also demonstrated through a case study.

  • The analytical experiments for fluid dynamics lead a sequence of complex scientific computations composing of numerical equations and require enormous computing resources with appropriate management tools. Currently most studies on e-Science environment for numerical studies focus on solving specific problems to drag out the best performance of matters and have less interest in providing a common framework to apply for diverse numerical domains in engineering education, especially for fluid dynamics. This paper presents an integrated e-Science experiment tool which could be easily applicable to solve various numerical analyses in fluid dynamics. As a proof-of-concept, an integrated e-Science framework with three numerical analyses has been designed and implemented over UNICORE that runs over grid computing environment.

  • In this paper, in order to improve the execution performance and serviceability of cross-platform applications frameworks based on the existing web applications, we design and implement a new hybrid application framework named as WApplE.js, which enables direct control of native UI(User Interface) of mobile operating systems and various resources via JavaScript. We first present the design results for the overall software structure and the configuration of every layer of WApplE.js, and then analyze the processes for calling and handling APIs in the implemented hybrid application framework. In addition, the results of comparison of features to the existing frameworks are presented.

  • The research in the field of quality engineering has mainly focused on the manufactured products. The philosophy and concept of the existing quality engineering should be equally applicable in the coming e-Business era. However, there would be numerous new quality-related issues in the e-Business environment, due to the fundamental change in the business processes, which did not exist in the past. This paper first proposes a framework for quality engineering research suited for the e-Business environment, and then identifies major quality-related issues that should be resolved in the near future. It also evaluates the potential usefulness and limitations of the existing quality engineering tools in resolving such issues.
