The existing CBD development methods deal with the analysis phase in a superficial manner. Applying such a superficial analysis to business applications with a number of subsystems makes analysis models be inconsistent with levels and styles, only depending on experiences of the analysts. This inconsistent analysis might cause more serious problems during the subsequent development phases, resulting in the failure of the projects. In this paper, we propose a rule-based analysis pattern that provides an analysis template for business applications. This pattern analyzes the concepts of business applications by using external events and internal rules that process the events. Employing this pattern, a huge business application can be developed by a couple of co-analysts who work together in a consistent and systematic manner. This paper also describes an efficient way to develop business components with the suggested analysis pattern using banking deposit case study through UML Components development process.

According to 2008 game white paper, it is reported that both the game developer's and the gamer's dissatisfactions about a game design have been increased recently. It is required to enhance the style of the development work flow and the communication manners to reduce such dissatisfactions. This paper suggests a method which can be used not only to simplify the development work flow but also to provide a satisfactory communication skill between the developer and the users. By speculating the mental recognition model, a knowledge representation model based on UML(Unified Modeling language) has been devised. Our approach can be successfully employed to conceive the user feedback and to articulate the original game design elements, thus provides a more concrete and flexible design process.

An Internet of Things(IoT) technology which provides intelligent services by combining context-awareness based intelligences, inter-communication is made of between things and things or between things and person through the network connected with intelligent things is spreading rapidly. Especially as this technology is converged into smart device, mobile, cloud, big data technologies, it is applied into various domains. Therefore, this is different from existing Web or Mobile Application. New types of IoT applications are emerging by adapting IoT into Web or mobile. Because IoT application is not only focused on software but also considering hardware or things aspect, there are limitations existing development process. Existing development processes don't consider analysis and design techniques considering both hardware and things. We propose not only a meta-model for development process which can support IoT application's development but also meta-models for main activities in this paper. Especially we define modeling elements by using UML's extension mechanisms, provide development process, and suggest design techniques how to apply those elements into IoT application's modeling phase. Because there are many types of IoT application's type, we propose an Android and Arduino-based on IoT application as a case study. We expect that proposed technique can be applied into many of various IoT application development and design with a form of flexible and extensible as well as main functionalities or elements are more concretely described. As a result, it brings IoT application's flexibility and the effect of quality improvement.

Recently, the number of people wishing to return to farming is increasing, However, the lack of farming experience and management information of returnees is one of the main reasons for increasing the probability of agricultural failure. This study proposes an interface to support early facility cultivation management decision-making for returnees who want facility cultivation. The proposed interface is designed with UML(Unified Modeling Language) and provides key decision-making information such as land/crop suitability, land/facility costs, and management costs according to input data such as cultivation areas, selected crops, and cultivation types selected by the user. Through the proposed interface, facility cultivators can effectively and quickly acquire initial decision-making information for facility cultivation in the desired target area.

This paper is to describe how to refer to software objects and reuse them through the web browser so that ail the members of the software development team can collaborate with each other on the development procedure, In addition, we describe how to convert the $ ^*$,mdl design information generated from the UML editor into their corresponding XML data, which is arranged to be saved in the relational database system. Furthermore, we provide a facet retrieval system based on which makes use of a object-oriented thesaurus, which supports an integrated environment through which all the project team members can share a lot of source codes and execution files as weil as object files produced from the web-based collaborative development environment. Finally, we have designed and implemented a web version management system that facilitates software developers to manage in their web-based search for the relationship of design informations.

스마트 디바이스(스마트폰, 태블릿PC 등)가 모바일 시장에 핵심으로 떠오르면서 새로운 스마트폰 플랫폼들이 등장하고 있다. 마이크로소프트에서도 스마트폰 경쟁에 뛰어들기위해 스마트폰의 요소를 강화한 윈도우폰 7을 발표하였다. 윈도우폰7 플랫폼이 현재는 스마트폰만 지원하지만 향후에 iOS나 안드로이드와의 경쟁을 위해 다양한 스마트 디바이스를 지원할 수 있을 것으로 예상된다. 그러나 다양한 스마트 디바이스들은 플랫폼은 같으나 디바이스의 용도에 따라 서로 다른 하드웨어 장치와 사용자 인터페이스를 가지고 있기 때문에 애플리케이션 개발에 많은 어려움이 존재한다. 이를 해결하기 위해서는 설계시점에서 다양한 장치들을 반영할 수 있게 모델링이 되어야한다. 이에 본 논문에서는 UML의 확장 메커니즘을 이용하여 윈도우폰7 애플리케이션의 모델링을 위한 확장 프로파일을 정의한다. 이를 위해 윈도우폰7이 가지는 특성을 분석하여 소프트웨어 구성요소와 하드웨어 리소스들을 분류하여 정의하였다. 이에 소프트웨어와 하드웨어 부분을 독립적으로 구현할 수 있으며, 윈도우폰7 플랫폼 기반의 새로운 스마트 디바이스가 출시되더라도 쉽게 확장이 가능하다.

Even though the distance education via web has a great advantage to overcome time and space, its problem is that the management of trainees is not efficient compared with classroom and group education. This problem is a great obstacle to the objects and achievement standards of distance education, giving controversial arguments to the advocators of distance education. Distance educators need to monitor the trainees'participation and responses continuously and offer appropriate feedback to the trainees. However, the existing distance education system only focuses on teaching and learning activities, and as a result, the efficient management function of distance education is not available. Accordingly, the study attempts to find out the appropriate managing elements of distance teacher training in order to effectively achieve the goals of teacher training and the efficient management of distance education. Also, it proposes distance teacher training management system that offers appropriate feedback to trainees, applying the derived elements of distance teacher training to the training processes. To verify the efficiency of the system, hypotheses on related items of distance teacher education and learning types are suggested, and the achievement degree of learning and its relations are investigated through questionnaire of learning types. In addition, a system using UML which is the standard of object-oriented modeling language is devised, so. that mutual management, language independence and convenient development environment as well as reusability can be offered, and so the design standardization and efficient system realization could be achieved, while flexible change of system according to education process and computing environment is possible.

In this paper, a mobile banking system which can provide banking services is introduced. Since a PDA has excellent features like a small-size computer and provides mobility, it has been widely used by salesmen. Therefore, if general banking services can be provided with PDA by using wireless technology, it will be very useful. In addition, it is easy to develop and maintain the client software of PDA because it uses Windows-based operation systems. In this paper, a PDA banking system is introduced. The system is designed and developed based on the techniques of wireless network, security and PDA programming to be used for mobile banking and a prototype system is developed. Moreover, we used the object-oriented modeling technique, UML and Java Beans for programming.
