In this paper, as a previous step of software development, through an analysis step in the basic design process of the FPSO crane, ERD, which could help develop common understanding between its developer and the user, was introduced. From the flowchart of the design process, the overall work flow in its development was understood. Then, after the design process of the crane was divided into many entities, the attributes of each entity were defined and the relationships between the entities were established, followed by ERD creation through the use of IDEF1X notation. The results of the analysis can be readily understood even by users who lack of software knowledge, and then their change requirements can be immediately reflected in the developed system that requires modification.

In general, flow analysis programs have been built in not JAVA language but such as Fortran, C or C++ because of a merit in performance of computation. However, most developer of those languages are not free for use. User should purchase the development tools of programs, and install it on their own computer. Fortunately, JAVA is a free software, and can be used to develop WEB-based programs. It is well known that the JAVA language is time consuming for calculating. However, the performance of computer power has been increased continuously, so it is sure that the former states can be overcome. In the present study, a flow analysis program, which is interactive with Graphics, using the Web-based programing language, JAVA, has been developed for solving the two-dimensional flow motion.

인터넷은 다양한 언어로 구성된 정보를 사용자들에게 제공해 준다. 따라서 인터넷 환경상의 정보 다국어화는 앞으로도 점차 가속화될 것으로 보인다. 그러나 각 국가별 지역 코드는 다국어 정보화를 가로막는 하나의 걸림돌이 되고 있다. 본 논문에서는 실사용자(end-user)와 개발자(developer) 환경에서 발생하는 다국어 지원의 문제점에 대해 알아보고, 이를 부산대학교 언어 정보 연구실에서 연구중인 다국어 지원 방법과 연관하여 특히 웹 환경에서 다국어가 동시에 지원될 수 있는 방안에 관해 연구하였다. 한글 환경에서 다국어가 원활히 지원되기 위해서는 유니코드 도입과 함께 다국어 입력 알고리즘이 개발되어야 하며, 이에 따른 다국어 입력 컨트롤 및 라이브러리 개발이 선행되어야 한다. 또한 웹 환경에서도 KS-C-5601 기반이 아닌 Unicode 기반 웹 환경 구축이 진행되어야 할 것이다.

In this paper, we introduce a system which helps to draw a conceptual class diagram from the problem description by combining various class diagram deriving methods. Generally, problem description is a kind of statements including user requirements in the early development phase. The system developer can derive a conceptual class diagram from this document, which playes an important role during the object-oriented software development. Until now, it is not easy for the novice to elicit classes because it requires good experience and intuition. In addition, there are also some difficulties of finding valid conceptual classes by hand when the size of system becomes larger. Therefore, we develop a system to solve these problems so that the developer is able to construct the conceptual class diagram easily.

This study is semiotic analysis about 'dumb ways to die' that is produced by Melbourne Railway of Australia in 2012. By analyzing the symbolic representations through 'Actants model' of A.J. Greimas, extract the relationship between signification of the represented object in 'dumb ways to die'. Greimas' model helps to analyze the semiotic interpretation action that occurs above a layer of discourse. In addition, this study is to compare the property to distinguish the Semiotic 'Actants' to cause the behavior of the recipient by represented in the same ideological situation. This can determine the properties of the signification and gauge the level of symbolic images that are reproduced in the discourse process. Accordingly, guidance to become a developer by extracting the reproduction principle of the video that causes a user's action.

Services for navigation and entertainment through AI-based voice user interface devices are becoming popular in the connected car system. Given the classification of VUI agent developers as IT companies and automakers, this study explores attributes of agent persona and user experience that impact the driver's perceived safety and satisfaction. Participants of a car simulator experiment performed entertainment and navigation tasks, and evaluated the perceived safety and satisfaction. Results of regression analysis showed that credibility of the agent developer, warmth and attractiveness of agent persona, and efficiency and care of the UX dimension showed significant impact on the perceived safety. The determinants of perceived satisfaction were unity of auto-agent makers and gender as predisposing factors, distance in the agent persona, and convenience, efficiency, ease of use, and care in the UX dimension. The contributions of this study lie in the discovery of the factors required for developing conversational VUI into the autonomous driving environment.

To analyze the applications of all types of mechanical systems, general purpose analysis programs have been developed and commercialized. However, it is customary to develop and use customized programs even though they sometimes require more work than a general purpose program. A customized program is simplified to adapt to a particular application from the beginning, is designed for small computers, and developed with hardware-in-the-loop in mind so it can be applied effectively. By adding design knowledge and bundling know-how to an analysis program, analysis time can be reduced. And because an analysis has to work in conjunction with other analysis programs, a proprietary program that the user can easily modify can be useful. In this thesis, a multi-body dynamics analysis system is presented using one of the most useful programming techniques, object-oriented concept. The object-oriented concept defines a problem from the physical world as an abstract object, an abstract model. The object becomes encapsulated with the data and method. Simulation is performed using the object's interface. It is then possible for the user and the developer to modify and upgrade the program without having particular knowledge of the analysis program. The method presented in this thesis has the following advantages. Since the mechanical components of the multi-body system converts independent modeling into a class, the modification, exchange, distribution, and reuse of elements are increased. It becomes easier to employ a new analysis method and interface with other S/W and H/W systems. To employ a new analysis method, there is no need to modify elements of the main solver and the Library. In addition, information can be communicated to each object through messaging. It makes the modeling of new elements easier using inheritance. When developing a S/W for the computer simulation of physical system, it is reasonable to use object-oriented modeling. Also, for multi-body dynamics analysis, it is possible to develop a solver that is user-oriented.
