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 IoT services platform is very important. In this paper, we develop an open IoT services platform and verified the function by building a testbed. Our platform based on the open source hardware and commercial cloud services such as AWS which is a component of an open service IoT platform.

Open-pit mining method, is safe relatively work as compared with underground mining. And high yield, low production cost, has the advantage that it can provide a lot of production. But deforestation, tailings and slag deposition, mineral debris, dust, water, noise, land subsidence, sediment runoff discharge, I have internalized environmental disaster predisposing factors, such as landslides. Thus, it may be noted, also by typical environmental regulations. We try to deal with the changes in open pit terrain and environment related issues. Then, use the recovery period and the open pit mine and ecology off the gun, environment-friendly development of accurate monitoring methods, systems of this development is required. The use of open platforms and open source GIS tools have been developed during this period, it needs to develop spatial information environment monitoring system open pit mine construction.

The interest on the Open Source Software(OSS) has been increasing as the Microsoft's latest Windows XP support ended. In this light trend, this study can contribute to the OSS marketing area. Specifically, it examined that the activation of online brand community about the OSS can affect to prosumer marketing of the OSS utilizing social media platform. In addition, the OSS social media platform users' loyalty for the OSS was investigated. The findings show that content, consumer support, UI, and reward among the activate factors of online brand community significantly affected to the activation of OSS social media platform. The brand reputation, however, was found insignificant to the activation of OSS social media platform. In addition, the activation of OSS social media platform can positively affect to their loyalty for the OSS. It means that participation to the social media activities about OSS and interaction with others in the network can help to form positive attitude for the OSS. In conclusion, the prosumer marketing utilizing social platform can be an important strategy as a new solution of the OSS business in the rapidly changing ICT ecosystem environment.

Moving forward on smart society, change of the way to solve the spatial issue used in information society is required. In order to be competitive and sustainable spatial information service, existing "spatial information open platform" strategy needs to be transformed into "spatial information social platform". The requirement for the spatial information open platform to be socialized and evolved into the spatial information social platform is investigated with respect to the characteristics of social platform P. Savalle(2010) suggested. Based on the investigation, the definition of spatial information social platform is formulated. Several roles of the government as a platformer to create and manage the spatial information social platform are suggested.

Recently many countries have established data platforms to disclose government-owned data that include administrative data-sets and provide free access to the public via Web. This research analyzes the "Socrata" and "CKAN", the most popular representative open data platforms in the world, and reviews functions and their practical cases in operation in several cities of various nations. It also examines the current status of the data-set services in the City of Seoul to provide conceptual bases for management and service of the local governments' data-sets using open data platform. Then it suggests measures that ensure the long-term preservation and management of data-sets as archives for services, which includes the aspects of preparing systems, creating and managing data, providing services, and selecting platforms.

Opened platform is called that anybody can be a producer and consumer in some platform. And many opened platforms are using in various area such as general goods, smart phone application and contents. In this paper, we will propose the opened platform system for the problems for evaluation the level of learners. Any user can register problems as public or private-type in this system and use them. So our proposed system has the advantage in selecting the high quality problems by continuous reviews about that even after they have been registered. Proposed system has three different modules such as submit, evaluate and produce problems modules. A user can submit various kind of problems in the submit module. The evaluation module is a module that allows the user who is not the problem registrant to evaluate the registered problem. The production module can use the registered problems for online and offline evaluation.
