클라우드 컴퓨팅은 정보가 인터넷 상의 서버에 영구적으로 저장되고 데스크탑이나 테이블 컴퓨터, 노트북, 벽걸이 컴퓨터, 휴대용 기기 등과 같은 클라이언트에는 일시적으로 보관되는 패러다임을 뜻한다. 가용성과 사용상의 편의에 대한 요구의 증가로 최근들어 빠른 속도로 발전하는 모습을 보이고 있다. 클라우드 컴퓨팅은 제공하는 서비스의 유형에 따라 IaaS(Infrastructure as a Service), PaaS(Platform as a Service), SaaS(Software as a Service)로 나뉜다. 이 중 IaaS는 인프라를 서비스로 제공하는 모델이다. 이를 구현한 오픈소스 클라우드 플랫폼으로 오픈스택과 클라우드 스택이 대표적이다. 시트릭스는 자사가 개발중인 클라우드 플랫폼인 클라우드스택을 아파치 라이센스로 전환하겠다고 발표했다. 이전까지 같은 종류의 클라우드 플랫폼인 오픈스택의 회원사로 참여하고 있던 시트릭스가 오픈스택 그룹에서 탈퇴하고 클라우드스택을 지원한다는 발표는 큰 관심을 받았다. 본 논문에서는 여러 오픈소스 클라우드 플랫폼 중 오픈스택과 클라우드스택을 비교해보고, 이를 통해 향후 오픈소스 클라우드 플랫폼의 발전가능성에 대해 고찰해보고자 한다.

Recently, through the development of IT and mobile technology, spatial information plays a role of infrastructure of the people life and the national economy. Many kinds of applications including SNS and social commerce is to leverage the spatial information for their services. In the case of domestic, spatial open platform that can provide national spatial data infrastructure services in a stable manner has been released. And many people have been interested to the open platform services. However, the open platform currently has many difficulties to analyze its service status and load in real time, because it does not hold a real-time monitoring system. Therefore, we propose a method that can analyze the real-time service status of the open platform using the analysis of the web server log information. In particular, we propose the results of the analysis as follows: amount of data transferred, network bandwidth, number of visitors, hit count, contents usage, and connection path. We think the results presented in this study is insufficient to understand the perfect service status of the open platform. However, it is expected to be utilized as the basic data for understanding of the service status and for system expansion of the open platform, every year.

본 연구의 목적은 오픈 러닝과 소셜 러닝 플랫폼의 핵심요소 비교분석 결과를 바탕으로 학습자와 학습 환경 개선을 위해 고려해야 할 핵심 요소와 방향에 대한 시사점을 고찰하는 데 있다. MOOC로 대변되는 오픈 러닝 사례들의 핵심요소를 분석하여 각각의 공통점과 차이점은 무엇인지 알아보고자 했다. 소셜 러닝 플랫폼을 활용한 사례들을 살펴봄으로써 소셜 러닝 플랫폼의 정의와 특이사항을 살펴보았다. 오픈 러닝과 소셜 러닝 플랫폼의 특이사항은 서로 어떤 상호작용을 가질 수 있을지 비교분석 내용을 바탕으로 오픈 러닝에서 발견 된 장단점과 소셜 러닝 플랫폼의 장단점으로 대치하여 서로 보완해줄 수 있는 진화한 러닝 플랫폼을 구상해보는 것은 유의미 할 것이다.

According to the NGIS (National Geographic Information System) project conducted since 1995, the central and local government has been accumulating huge amount of geospatial data. Korean Ministry of Land, Infrastructure and Transport started its GeoSpatial open platform (V-World) service in January 2012, also offering a wide range of functions and services. However, the National GeoSpatial open platform is still woefully deficient for the users to find their desired data, lack of data for private business area, insufficient in publicity of local government and public-private partnerships. Through analyzing current research trend after GeoSpatial open platform served for three years, study on overseas expansion, system links, service improvement, utilization and future strategy has been mainly conducted. This study, by analyzing the advanced overseas GeoSpatial platform as well as domestic research trend and combining the concept of new technology, business platform and SMG (Seoul Metropolitan Government)'s GeoSpatial platform, proposes a policy for the construction of future GeoSpatial Open Platform model.

Since the Spatial Information Open Platform service started in January 2012, the number of service users and the size of the system has increased significantly. However, we could not know the analysis result about how much the hardware resources of the Open Platform system can handle user services. Thereafter, whenever the number of service users are rapidly increased, we simply have solved the service delays using the hardware extension. So, this study presents the obvious solution to avoid the same problem in the future, by pinpointing the system performance of the Open Platform. In this study, through the performance analysis of hardware using NMON and the load test of web service using nGrinder, we intend to get an accurate performance of the Open Platform system. Then we intend to present the resource reallocation method in order to provide better performance of the system.

As the concept of open source extends beyond the scope of software, many companies are also introducing business models using open source concepts. This study is a study on how to create a web-based open-source platform using a 3D printer and aims to create an open-source platform modeled on the Kidults community where users are highly willing to participate. The research method established the direction of initial platform production by collecting basic data through the usability of the platform and Toy design preferences and propensity analysis through research on open source use cases by various companies and user surveys in the Kidults Community. Features unique platform Toy sources that are freely reinterpreted by the user and re-shared and sold to the platform. Research should continue to boost user motivation by activating communities within the platform.

Recently, the utilization of geospatial open platforms has been constantly increased and the interest in 3D geospatial data such as terrain, building and shopping mall has been increased significantly. In particular, rather than simplified 3D geospatial data, interest in high-precision 3D geospatial data which similarly represents the real world objects has increased significantly. In order to satisfy the demand for such the high-precision 3D geospatial data, various kinds of 3D geospatial open platforms has been developed and has provided services on the web. However, most of the 3D geospatial open platforms have been used plug-in module in order to ensure a fast 3D rendering performance on the web, despite the many problems such as difficulty of the installation, no supporting of cross browser/operating system and security issues. In addition, recently, the existing 3D geospatial open platforms based on plug-in module are facing a serious problem, by declaring the NPAPI service interruption in Chrome and Firefox browsers. In this study, we presents the design and implementation of a new 3D geospatial open platform based on HTML5/WebGL technology without the use of plug-ins. Such the new 3D geospatial open platform based on HTML5/WebGL may support cross browsers such as IE, Chrome, Firefox, Safari and cross OS platforms such as Windows, Linux, Mac and mobile OS platforms.

In order to expand the market of the domestic space information industry, which is currently saturated, overseas expansion is essential, but the prospects are limited. Therefore, an effective strategy of overseas expansion is needed. Given the current state of such spatial information industry, V-World is expected to play a very important role. In the world market for space information, in order to ensure the export competitiveness of the domestic space information industry, in the present study, research and development was carried out on the V-World-based packaged goods model as one possible method. First of all, to analyze the current situation and characteristics of the spatial information industry, to grasp V-World as a commodity and derive the relationship between foreign demand and V-World, the sales destinations and methods were defined. To formulate the basic strategy of the fusion-composite package export utilizing V-World on the basis of the basic concept of the product, the necessary components were designed. In response to this fusion-composite package product mix, the overseas promotion of spatial information-related companies it to be expected.
