  • Unused land is a new load of building and a linear improvement, expanding the loss of function of the road abandoned road construction sites, as well as existing roads is possible additional advantage. However, some space is overcharge checkpoints, materials yard, make this vehicle utilization and maintenance of the unfavorable situation, as vehicle rest area but unused land most of the space required for the use of the system management plan. We are analyzed the location, topographical features, cultural property and in the space which is geospatail open platform set up to classify the type of unused land. Depending on the type of unused land using the geospatial open platform performs a 3D model and a proposed model development and application taking into account the environment and landscape. To derive the Gangwon development Plan and design of future route unused land was becoming helps you make better use of unused land.

  • As open data(public data) began to be recognized as a source of national economic development, many countries began to build public data portals and provide open data to the private sector. In accordance with this trend, open source communities have begun to develop open data platform such as CKAN and enable to share dataset among open data platforms by applying metadata standard technology. However, many governments and local governments are still making it difficult to share data between data portals because they build their own platforms. In this paper, we propose a DCAT-based metadata transformation tool to solve these problems, and show how to transform a dataset into DCAT.

  • Current strategic trends in service distribution and software development in response to Web as a platform represent a paradoxical concurrent pursuit of 'economy of scale' and 'service'. From the software perspective, the major novel elements of the Web 2.0 era are Web as a platform and the emergence of long-tail service enabling web sites to function as an independent distribution channel. The current study analyzed the platform strategy for establishing a community of interactive developer and customers taking the issue of economy of scale into consideration. Software industry should face the new reality and utilize the open source community for cost minimization and securing customer base. Furthermore, Lego-style software development should be adopted for maintaining cost-competitiveness in customized software development.

  • The era of IoT in which all objects are intelligent and are connected to the Internet has been started. In order to establish and activate an IoT eco system, open services platform is very important. In this paper, we developed a BLE sensor module as a component of the open service platform based on the IoT and the open source hardware Blutooth4.0. To verify the functionality and performance of the developed BLE sensor module was built to evaluate the performance of the test environment.

  • The era of IoT in which all objects are intelligent and are connected to the Internet has been started. In order to establish and activate an IoT eco system, open services platform is very important. In this paper, we developed a gateway that utilize the Raspberry Pi which is open source hardware for IoT open service platform. The gateway supports a variety of wireless interface and equipped with MQTT, a standard messaging protocol for IoT. To confirm main function of developed gateway, we built a IoT test bed and verified normal operation of our gateway.

  • Open source software allows revising and adding a new idea on them as well as debugging themselves. The open source software can be utilized as various educational programs as well as development of a commercial software products using them. MIT App Inventor, one of the block-based visual programming environments for education, supports building a local server and even revision of the platform itself by providing its own source codes. In this paper we implement App Inventor open sources on the local server. Especially we present how to revise and implement a new App Inventor platform reflecting their own requirements in schools or educational institutes and how to build a local server operating the revised App Inventor platform. They can provide more interactive educational environments to students and improve educational satisfaction through the active customizing of the platform itself such as adding new programming block components requested by students.

  • 본 논문에서는 다양한 하드웨어를 능동적으로 관리할 수 있는 미들웨어 시스템을 제안한다. 최근 WII Remote, KINECT와 같은 게임기에서 사용되는 하드웨어를 일반 데스크톱에서 사용하고자 하는 노력들이 많이 이루어지고 있다. 뿐만 아니라 RFID, 블루투스, 이동전화 등 기존에 나와 있는 다양한 기기들도 데스크톱에서 이용할 수 있도록 많은 기술적 접근이 이루어지고 있다. 각각의 디바이스를 관리하기 위해서는 그에 맞는 디바이스 드라이버와 API를 만들어야만 한다는 단점이 있다. 제안하는 시스템은 시대적 흐름에 맞추어 다양한 하드웨어 시스템을 효율적으로 관리할 수 있으며, C, C++, C#, JAVA의 다양한 언어로 구현된 어플리케이션을 하나의 미들웨어 위에서 동작시킬 수 있는 큰 장점이 있다. 기존의 미들웨어는 이종 다바이스간의 데이터 호환 및 처리를 수행하였지만 본 논문에서 제안하는 시스템은 이종 플랫폼간의 데이터 호환까지 지원한다.

  • Embedded linux system cann't take up the X-window-based GUI platform commonly used in PC platforms because of low performance in hardware. For the GUI implementation in embedded linux system, the lightwieight graphic library is needed, which supports simplified functions and the usage of little resource. In this paper, several of popular open-source graphic libraries are selected and evaluated for the adoption of an efficient library in the GUI implementation for multimedia embedded system requiring the simple and intuitional user interface.

  • 구글 안드로이드 플랫폼은 오픈소스 형태로 응용프로그램을 손쉽게 개발할 수 있는 환경을 제공하며 이러한 특징으로 인해 빠른 속도로 시장 점유율을 높이고 있다. 하지만 오픈 소스의 특징으로 인해 보안 취약점에 대한 우려가 증가하고 있다. 안드로이드 고유의 보안모델은 응용프로그램의 시스템자원에 대한 부적절한 접근을 제어하기 위한 권한을 중심으로 이루어진다. 본 연구에서는 안드로이드의 권한 기반 보안모델에 대한 취약성을 테스트 코드수행과 플랫폼 소스분석을 통해 알아보고 이에 대해 간단한 해결방안을 제시한다.
