We have developed an information management tool for the EDISON (EDucation-research Integration through Simulation On the Net) open platform. EDISON is, at present, a web-based simulation service for education and research in five computational areas, namely, nanophysics, fluid dynamics, chemistry, structural dynamics, and computer aided optimal design. The EDISON open platform consists of three tiers: EDISON application framework, EDISON middleware, and EDISON infra-resources. The platform provides web portals for education and research in areas such as computational fluid dynamics, computational chemistry, computational nanophysics, computational structural dynamics, and computer aided optimal design along with user service. The main purpose of this research is to test the behavior of the release version of the EDISON Open-Platform under normal operating conditions. This management tool has been implemented using the RESTful API designed in EDISON middleware. The intention is to check co-operation between the middleware and the infrastructure. Suggested tools include User management, Simulation and Job management, and Simulation software (i.e., solver) testing. Finally, it is considered meaningful to develop a management tool that is not supported in other web-based online simulation services.

The market of platform business is typically served by a few dominant players, presenting "winner-takes-all" phenomenon. This study aims to find service characteristics leading to the phenomenon. Six different service-characteristics were considered : Same-side network effect, cross-side network effects, entry barrier, multi-homing cost, switching cost, and heterogeneity of preference. To assess the degree of concentration of market share, HHI (Herfindahl-Hirschman Index) is calculated for top three major players. Based on the HHI value, 10 most eminent platform businesses are classified into three different segments and each segment is characterized with key factors. The results from this study provide some insight into the strategic management of platform business.

Radiation work always carries the risk of radiation exposure, so regulatory agencies manage it through licensing when high exposure is expected. However, due to passive management methods using TLD, etc., there are cases where risk management is done after an incident occurs or the incident is covered up. In this study, we developed a system to manage the location of radiation work and the risk of workers in real time through a safety management platform and a location-based personal dosimeter. The safety platform server receives data from the developed personal dosimeter in real time and manages risks in three steps for each worker using location and dose rate, and can predict risks and generate alarms in real time. The personal dosimeter transmits the location and dose rate of the worker in real time using GPS and LTE communication. The developed safety management platform and personal dosimeter were verified through a field test to receive real-time data of the location and dose rate data of the worker, and the risk management function according to the individual dose rate was verified.

With the energy paradigm shift from supply side management to demand side management, many researches have been done on demand side resource management and demand response. At the same time, Obix, BacNet-WS and OPC-UA are popularly used in buildings and industry energy management system. However, it is not easy to interchange the data and information among the systems cause a variety of protocols are used in buildings and factories. Therefore, in this paper, we are proposing an open business platform not only to integrate and manage the demand resources using various protocols and standards, but also to allow to plug-ins a new business service on top of the platform.

This study focuses on the network externality effect related to the platform supplementary services. This study designs the network externality of platform and suggests a supplementary service adoption model. Additionally, this study examines the moderating effect of demand forecasting for the platform. Using AMOS program, a structural equation modeling has been used to analyze the research model. The findings can be summarized as follows : First, we find out the structural relationship among the factors (usefulness, perceived value, purchase intention) affecting adoption of the supplementary services. Second, positive perception of platform flow can promote the platform interaction. Third, positive perception of present users based on platform can arouse friendly evaluation in the platform interaction. Fourth, loyalty to the platform brand can improve the perceived usefulness of supplementary services, but cannot lessen the resistance to supplementary service cost. In addition, the moderating effects of demand forecasting for the platform in the path leading from platform factors to supplementary service factors were identified. In conclusion, traditional brand strategy may be effective in platform marketing activities but the extent of performance in the strategy can appear to be quite different. Therefore, taking the relationship with network externality into consideration should be involved in the marketing strategy in platform.

유비쿼터스 도시의 개념이 등장하면서 도시 관리에 대한 중요성이 점차 높아지고 있다. GIS는 도시를 효율적으로 관리하기 위한 기반이며 u-City 구축사업에 있어 필수적인 기술이다. 시민의 삶의 질 향상을 목표로 하는 u-City는 공공서비스를 중심으로 발전된 IT기술과 접목되어 다양한 서비스의 제공을 시도하고 있으며 기술의 진화에 따라 더 많은 서비스를 추가로 적용할 예정이다. 이러한 추가 서비스가 쉽게 개발되어 더 많은 양질의 서비스를 시민에게 제공할 수 있게 하며 유기적인 정보공유 환경을 제공하는 것이 u-City 통합운영플랫폼이다. 이러한 통합운영플랫폼에 u-City 서비스를 위한 GIS 요구 기능을 정의하고 공통 구현이 가능한 기능들을 통합하여 제공한다면 보다 효율적인 도시 관리를 실현할 수 있을 것이다. 이에 본 연구에서는 u-City 서비스를 위해 구축되는 통합운영플랫폼들에 적용되고 있는 GIS 요구 기능을 분석하고 이를 기반으로 실제 u-City 서비스 중가로등관리 및 화재감시에 대한 GIS 모듈을 구현하였으며 이의 서비스 시뮬레이션을 수행하여 통합운영플랫폼의 GIS 공통 기능 적용에 대한 활용성 검증을 수행하였다.

Efficient management of the construction heavy equipment is required to reduce the rate of carbon emissions and on-site accidents. The intelligent excavation system (IES) will improve the construction quality and productivity through information technologies and efficient equipment operation, especially in large earthwork projects. Three-dimensional digitized ground data should be required for identifying the path of heavy equipment and work-site environment. Rapid development of terrain laser scanners (TLS) is more readily to acquire the digital data. This study suggests the '3D ground terrain processing platform (3DGTPP)' including data manipulating module and analyzing module of the scanned data for intelligent earthmoving equipment operation. The processing platform consists of six modules, including scanning, registering, manipulating, analyzing, transmitting, and storing. 3D ground terrain processing platform presented in this study will provide fundamental information for intelligent excavation system (IES), which will increase the efficiency of earthworks and safety of workers in significant.
