  • Along with the evolution of wireless internet environment, information services in mobile internet are being explosively increased. However, due to the high expense for the use of those services, it is not easy to collect the devoted customers. In order to overcome the adverse conditions, the service should be supported by a strategic application system which facilitates easier and fast service for customer's information needs than that of traditional on-line internet. In this paper, we investigate the strategy how to provide the information service under the customer satisfaction, and also consider some ways of personalization of information service and information provision in real-time. As a result of the works, we develop a system, MoSA-CRM(Mobile Service Application based on CRM) to support customer-oriented information service. We believe that the MoSA-CRM system can provide some benefits for information providers in mobile e-commerce market such as flexibility in business strategy, systematic customer relationship management, and growth in financial ability.

  • Object-oriented development methodologies require consistent and seamless object-oriented paradigm to be applied from analysis to testing. Testing must focuses on the state of aggregated objects. This paper suggests testing methods that satisfy such requirements. In order to confirm appropriate implementation of the user requirements, the methods apply extended use case[Jacobson et al., 1992] that are prepared form analysis stage. Testing must be performed based on the use cases because the user requirements are formally documented in the use cases. The notations of the original use case are modified for the state-based testings. The testing methods consist of a unit testing and four-level of integration testing. Particularly, the level 0 testing is based on FREE state machine [Binder, 1995, 1996]. The testing methods have been applied to 3 projects and proved their practicability.

  • It has been argued theoretically and empirically that the analysis of business processes requires the decomposition of an integrated system. However, in order to innovate a business process, cognitive integration activities that try to understand the decomposed features of the business process as an integrated system are essential. This research aims at 1) empirically investigating the cognitive process of integrating multiple diagrams while using object-oriented methodologies in process modeling ; 2) identifying a cognitive integration strategy that supports the successful comprehension of business processes with the use of multiple diagrams ; and 3) proposing guidelines for developing supporting tools for effective business process engineering by using object-oriented process modeling.

  • Intranet emerges as a key technology for building enterprise information system. This paper proposes a scenario-based object- oriented technique for designing intranet hypermedia information systems. The method consists of six phases such as domain analysis, object modeling, view design, navigational design, implementation design and construction. Users requirements are analyzed in the form of scenarios by the use fo a responsibility-driven object technology. Object-oriented views are generated from the resulting object model and then used for the subsequent navigational and implementation design. Implementation design phase deals integrating enterprise databases with distributed hypermedia systems by employing Java language. To demonstrate its usefulness, a real-life bank case is illustrated.

  • This study aims at providing basic data for the beauty industry to establish more reasonable marketing plans for women in identifying their Lifestyles, observing and analyzing their purchase behavior for beauty service. Women were classified into four types: fashion appearance oriented type, sociable personality oriented type, brand oriented type, fashion indifferent type. The result of the differences between their lifestyles and purchase behavior for beaty service is as followed. Purchasing behaviors, such as motives of purchase beauty service, beauty service information search, beauty service estimation standards were made a difference in lifestyle types.

  • There are a lot of shopping malls in Internet and most of consumers want to buy good goods in cheap price through the shopping malls. To support them, many sites for price comparison are constructed. But man or woman search many shopping malls and insert their price informations into database that the price comparison sites own. To overcome this disadvantage, virtual shopping malls are builded. These virtual shopping malls are connected and cooperated a lot of affiliated existing shopping malls for the cheapest price information. But, these virtual shopping mall are connected to those existing shopping malls in synchronous. So If they are connected to many existing shopping malls, we have to wait long time because of searching for many existing shopping malls. In this paper, we designed and implemented a virtual shopping mall that connect to many existing shopping malls in asynchronous. For a asynchronous communication between this virtual shopping mall and many existing shopping malls, we used JMS (Java Message Service) that is a standard Java API for MOM (Message-Oriented Middleware).

  • An understanding of quality attributes is relevant for the software organization to deliver high software reliability. An empirical assessment of metrics to predict the quality attributes is essential in order to gain insight about the quality of software in the early phases of software development and to ensure corrective actions. In this paper, we predict a model to estimate fault proneness using Object Oriented CK metrics and QMOOD metrics. We apply one statistical method and six machine learning methods to predict the models. The proposed models are validated using dataset collected from Open Source software. The results are analyzed using Area Under the Curve (AUC) obtained from Receiver Operating Characteristics (ROC) analysis. The results show that the model predicted using the random forest and bagging methods outperformed all the other models. Hence, based on these results it is reasonable to claim that quality models have a significant relevance with Object Oriented metrics and that machine learning methods have a comparable performance with statistical methods.

  • HLA (High Level Architecture) 는 모델링과 시뮬레이션 분야에서 상호 이질적인 서비스에 따른 어플리케이션의 상호운용성(interoperability)과 재사용성(reusability)을 증진시키기 위해 필요한 infrastructure를 개발하기 위한 청사진이다. RTI(RunTime Infrastructure)는 HLA 의 소프트웨어적 도구로써 IibTRI, FedExec, RTIExec의 세 가지 컴포넌트로 구성되어 있다. RTI는 분산환경에서 동적으로 다수대다수간의 통신을 제공하는 미들웨어 (middleware)이다. 대규모의 분산 시뮬레이션의 실행은 지리적으로 퍼져있는 많은 양의 컴퓨팅 자원을 필요로 할 수 있는데 이러한 환경이 가지는 보안과 동적 자원 할당이라는 문제점을 Globus Toolkit3(GT3)안의 Open Grid Service Arcitecture(OGSA)를 사용해서 해결할 수 있는 RTI-G를 개발해 왔고 이를 service-oriented RTI-G라 부른다. 이 논문에서는 service-oriented RTI on Grid 의 구조와 앞에 제시된 문제점들의 해결방안을 제시하고 실험한다.
