IT environment gets more complicated in terms of open platform, network standards, device design and hardware, etc. Smart network and application are in the fields of corporate as well as national competition for future fusion technology. In development environment focused on computers, the ideas of authoring tool have been presented in terms of improved software productivity. In smart environment where subdividing works are consecutively done, current authoring tool should be effectively updated for effective development of programs and easier access to business works. The basic concept of a new conceptual App development tool, Smart App Authoring Tool, which has been designed in this study and enables to apply on-site requirements to smart phones, is to develop Apps on the level using easy-to-learn Word or Excel in a computer. Therefore, this study is intended to design a conceptual Smart App Authoring Tool to optimize the cost and time for developing and maintaining new application services under various smart phone platform environments. Based on the performance of smart app authoring tool herein, every people can develop a smart app program at moderate level. So this paper have designed a conceptual smart app authoring tool. This study presented educational efficiency of the authoring tool by developing business Apps under various business environments and applying them under university and high school environments.

Technology of GIS evolved as a means of assembling and analyzing diverse spatial data. Many systems have been developed, and almost of systems are proprietary. There is a lots of lack of interoperability and reusability between them. This paper describes the development of Open GIS component software. The developing system have an end in view of GIS tool software which is interoperable and reusable. To increase the interoperability and reusability, the system is based on the OGC(Open GIS Consortium)'s Open GIS Simple Features Specification for OLE/COM. The OGC's specification is announced to increasing the full interoperability of various geospatial data and geoprocessing resources. With the Open specification, component based software ensures the reusability. We implement three kinds of component: Geometry component, Spatial Reference System Component, and MapBase Component. The first two components are compatible to the OGC's specification and the third one is designed to GIS tool software for variant GIS applications. The Open GIS component software system is developed on object-oriented computing environment, ATL/COM and Visual C++. As we made application programs using Visual Basic, the advantages of component based Open GIS software was proved.

오픈 소스 프로젝트가 다수의 개발자들에 의해 진행될 때 동일한 파일에 대한 여러 버전을 관리해 주는 버전 관리 시스템은 매우 유용한 도구로 사용되고 있다. 그러나 대부분의 기존 버전 관리 시스템들(SVN, Git 등)은 소스 코드 혹은 문서의 변경 이력을 주로 관리하고 있기 때문에 개발 환경의 변경이 발생할 때마다 개발자마다 직접 변경해야 하는 불편함이 있다. 이러한 불편함을 해소하기 위하여 본 논문에서는 오픈 소스 프로젝트를 위한 버전 관리 기법을 제시한다. 제시한 기법의 기본 개념은 컨테이너 방식의 가상화 도구인 도커를 이용하여 개발 환경을 포함한 이미지를 생성하고 이를 새로운 버전으로 관리한다. 제시한 기법의 기능적 타당성을 검토하기 위하여 서로 다른 OS(우분투12.04, 센트OS7)를 사용하는 호스트에 도커를 구축한 후 개발 환경의 변경 이력이 포함된 버전 관리를 실험하고 기존 버전 관리 시스템들과 비교 평가하였다. 그 결과 제시한 기법은 오픈 소스 프로젝트를 위한 편리한 버전 관리 기법이 될 수 있을 것으로 보인다.

In this paper, we focus on the process of using open source software (OSS) and factors that should be considered when using project-based OSS. We also elaborate on how to avoid using OSS licenses in an OSS-based technology development process, why dual OSS licenses and security threats should be avoided, and the method of notification after use. In addition, the OSS license verification method and environment are described in the course of project development. In the verification method, the OSS license used for technology development in the course of project execution is validated in advance by the person who decides whether or not to use the OSS, and then additional verification using the tool after technology development. It is expected that this paper will be helpful for establishing the OSS usage consideration and the license verification procedure, and environment in the future.

In this paper, we developed a Windows 95 version off-line programming system which can simulate a track vehicle model in 3D graphics space. The track vehicle was adopted as an objective model. The interface between users and the off-line program system in the Windows 95's graphic user interface environment was also studied. The developing language is Microsoft visual C++. Graphic libraries, OpenGL, by Silicon Graphics, Inc. were utilized for 3D Graphics.

Detailed analysis of the neutron pathway through matter inside the nuclear reactor core is exceedingly needed for safety and economic considerations. Due to the constant development of high-performance computing technologies, neutronics analysis using computer codes became more effective and efficient to perform sophisticated neutronics calculations. In this work, a commercial pressurized water reactor (PWR) presented by Virtual Environment for Reactor Applications (VERA) Core Physics Benchmark are modeled and simulated using a high-fidelity simulation of OpenMC code in terms of criticality and fuel pin power distribution. Various problems have been selected from VERA benchmark ranging from a simple two-dimension (2D) pin cell problem to a complex three dimension (3D) full core problem. The development of the code capabilities for reactor physics methods has been implemented to investigate the accuracy and performance of the OpenMC code against VERA SCALE codes. The results of OpenMC code exhibit excellent agreement with VERA results with maximum Root Mean Square Error (RMSE) values of less than 0.04% and 1.3% for the criticality eigenvalues and pin power distributions, respectively. This demonstrates the successful utilization of the OpenMC code as a simulation tool for a whole core analysis. Further works are undergoing on the accuracy of OpenMC simulations for the impact of different fuel types and burnup levels and the analysis of the transient behavior and coupled thermal hydraulic feedback.

In the future, a machine-tool will be more improved in the form of a knowledge evolution based device. In order to develop the knowledge evolution based machine-tool, this paper proposes the structure of standard M2M(Machine To Machine) and the scheme of agent communication in environment. The communication agent such as dialogue agent has a role of interfacing with another machine for cooperation. To design of the communication agent module in M2M environment, FIPA(Foundation of Intelligent Physical Agent) and ping agent based on JADE(Java Agent Development Framework) or FIPA-OS(Open Source) are analyzed in this study. Through this, it is expected that the agent communication can be more efficiently designed and the knowledge evolution based machine-tool can be hereafter more easily implemented.

본 논문에서는 사용자 인터페이스(UI) 모델로부터 모바일 웹앱을 자동으로 생성하는 도구를 제시한다. UI 모델은 UI 중심적인 내장형 시스템을 UI 모델링을 통해 효율적으로 개발하기 위한 방법인 PELUM(Pattern and Event based Logical UI Modeling)을 기반으로 한다. 본 논문에서 제시하는 도구는 모델 편집기와 코드 생성기로 이루어져 있다. 모델 편집기는 웹 상에서 논리적 UI 모델(LUM)과 프로그래밍 인터페이스 모델(PIM)을 모델링하는 환경을 제공한다. 코드 생성기는 LUM을 기반으로 앱의 화면구성 및 이벤트 동작을 설정하고 PIM을 기반으로 로컬 데이터베이스 스키마를 자동으로 구성하여 모바일 웹앱을 생성한다. 또한 PIM에서 외부 혹은 open API 주소를 입력 받아 매쉬업 웹앱을 생성하는 기능도 제공한다. 생성된 모바일 웹앱은 사용자가 손쉽게 최적화할 수 있도록 Model-View-Controller(MVC) 아키텍처로 구현하였다. 이를 통해 사용자는 웹 상에서 UI를 모델링하여 여러 기기에서 동작 가능한 모바일 웹앱을 생성할 수 있다.

본 논문은 구성원들 사이의 자원공유를 원천적으로 봉쇄하는 일반적 협업개발 지원도구의 한계를 극복하고, 조직의 여러 사용자들에게 자원 공유의 기회를 제공함과 동시에 자원공유에서 발생하는 버전관리와 충돌문제를 해결하기 위한 방법을 제시한다. 개발된 소프트웨어 협업개발 지원도구는 전통적인 낙관적 기법을 적용하되 충돌해결에 드는 비용과 노력의 절감을 위한 개선된 알고리즘을 사용한다. 시스템의 구조는 전통적인 Client/Server 방식에 개인간 정보교환을 지원하는 P2P(peer-to-peer) 방식이 결합된 형태로 이루어져 있으며, 공개 소프트웨어인 CVS(Concurrent Version System)를 기반으로 구현되었다. 이를 바탕으로 대표적인 기존 협업개발 지원도구들과의 유용성 비교를 통해 기능적 효율성을 확인하였다.
