  • 멀티에이전트 시스템(MAS: Multi-Agent System)에서 에이전트는 각자의 목표 달성을 위해 주위 에이전트들과 상호작용하여 목표의 충돌이 없는 일치 상황에 도달하도록 설계될 필요가 있다. 이러한 상호작용은 MAS에서의 협동, 공조, 그리고 협상 등의 분양에 필수적인 요소이다. 본 연구에서는 MAS에서 믿음(Belief), 소망(Desire), 그리고 의도(Intention)를 에이전트 구조의 핵심 요소로 가정하고, FIPA Agent Communication Language(ACL) 사양과 interaction 프로토콜의 변형에 기초하여 BDI 에이전트를 위한 협상 프로토콜을 소개한다. 또한 Java와 Prolog를 결합시킨 InterProlog 프로그래밍 언어로 목표 충돌을 일으키는 BDI 에이전트들을 생성하고 에이전트들이 협상 프로토콜을 사용하여 협상하는 과정을 시험적으로 구현한다.

  • In this paper, we proposed a downscaled 3D object technique using medical images for telediagnostic use. The proposed system consisted of downscaling/thresholding processes for building a downscaled 3D object and a process for obtaining 2D images at specific angles for diagnosis support. We used 80 slices of Digital Imaging and Communication in Medicine(DICOM) CT images as sample images and the platform-independent Java language for the experiment. We confirmed that the total image set size and transmission time of the original DICOM image set using a down-scaled 3D object decreased approximately $99\%\;and\;98.41\%,$ respectively. With additional studies, the proposed technique obtained from these results will become useful in supporting diagnosis for home and hospital care.

  • In this paper, We designed the robot controller with Linux OS, Cygwin under the Marvell Monahan PXA320 embedded platform. Cygwin is a collection of tools for using the Linux-like environment for commercially released x86 32 bit and 64 bit versions of Windows and is a DLL that acts as a Linux API emulation layer providing substantial Linux API functionality. TinyOS-2. x is a component based embedded OS by UC Berkeley and is an open-source OS designed for interfacing the sensor application with specific C-language. The results of experiment are described to show the improvement of sensor interfacing functionality under the PXA320 embedded RTOS platform.

  • In this study, we proposed a web-based teleoperation system to enhance the productivity and flexibility of the greenhouse since basically, internet-based teleoperation enables cheap, expandable system to be implemented. Platform independent language, Java-based control system can overcome the platform dependency which most of conventional control systems have. One of the merits of the proposed system is the flexibility of the data based system from which some valuable analysis can be implemented on-line. Some basic experiments show the stability and field applicability of the proposed remote control system.

  • Recently, industrial business environments have rapidly changed and face severe competitive challenges. The effective inventory system enables to product and deliver the products quickly for meeting due date of customer's order in this environment. This study have developed a web-based inventory system framework using RFID for a plastic injection molding industry. The system analysis inventory problem issues such as inventory planning, warehouse assignment. In this study, web-based inventory system using Java language is proposed and implemented. As the result of implementation of the system, we expected that it manages to inventory planning continually and systematically.

  • The Web-based simulation was introduced for conducting simulation experiments in the Internet and the Web. Due to the use of the Java language, the Web-based simulation can have such characteristics as reusability, portability, and the capability of execution on the Web. Most of existing Web-based simulation tools have focused mainly on the development of the runtime simulation libraries and mechanisms on the Web. Thus, the model development work in such Web-based simulation tools still requires hand-written coding of model developers. This paper presents a visual model development environment for the Web-based simulation. The proposed environment provides a framework for model development and animation. To show the effectiveness of the proposed environment, we perform simulation experiments for transaction routing algorithms in a distributed transaction processing system.

  • SW 교육에 있어서 입문자의 흥미를 유발하고자 블록 기반인 스크래치와 엔트리가 도입되었고 많은 교육 기관에서는 이후 ARDUINO, C, JAVA, PYTHON 등을 선택 교육하고 있다. 이 과정에서 코딩보다는 사고력을 강조하며 정보 교과 내에서 문법 공부하는 것을 기피하는 풍토를 보인다. 이러한 점은 2015 개정 교육과정 지침에서 특정 언어의 기능습득에 치우치지 않고 학습자의 수준에 맞추어 적절한 도구를 선택하도록 하여 사실상 교수자의 재량에 두고 있는 점에서도 파악할 수 있다. 코딩의 문법학습을 피하는 경향은 코딩교육 도입 초기의 취지와는 다르게 공교육 내에서의 코딩교육의 활성화에 부정적 요소로 작용할 여지가 크다고 우려된다. 따라서 현재 출판된 정보 교과서에서 다루는 프로그래밍 언어의 종류를 조사하고 코딩 문법학습을 최소화를 할 수 있으며 블록코딩에서 텍스트 코딩으로 전환 시 학습자의 부담을 감소할 수단으로 PROCESSING를 통한 과정을 제안하는 바이다.
