Building Information Modeling, which was applied mainly in the construction sector, is expanding to the road sector, and the government recently recommends preparing individual application guidelines considering the characteristics of detailed fields such as railways, ports, and complexes through BIM implementation guidelines. Compared to general construction projects, a lot of the works such as signals, electricity, and power, and the railway BIM 2030 roadmap has been presented to apply BIM to railway construction projects that require business consultation and work environment review with various local governments, and pilot projects are in operation. Unlike a general building, in which the construction begins after the detailed design is completed, in the railway project, the detailed design of other works proceeds along with the roadbed construction. Because construction and design work together, railways need to coordinate detailed engineering interfaces such as trajectories, signals, and power, and the application of BIM in design interface coordination has the advantage of maximizing the effectiveness of pre-review. Overseas railway construction projects actively used BIM to adjust design interfaces and had a collaboration process to modify BIM models and create construction details from the revised models through regular meetings with suppliers. Therefore, this study aims to derive the factors necessary for establishing a BIM collaboration environment based on a survey of practitioners as a preliminary step for establishing the BIM collaboration process of the railway construction project.

The elderly rate in South Korea in 2013 is over 12%. Especially, the elderly rate in rural area is 36%, i.e., in rural area, one of three is people aged 65 and over. Senior community project in rural that is being promoted by the government. This project is to improve the quality of life health and welfare services for the elderly in rural Area. This paper investigates cases used as living space by interview and remodeling senior centers (village community center) for the elders living alone in rural areas. In Gimje two the nation's first senior centers were remodeled in 2006 (for both the village community center) and were begun to use these as group homes. Evaluation was a success. Since then, these were increased by approximately 20 centers per year by year and are currently 108 centers at the end of 2011. In Chungcheongnam-do, a pilot project has been begun for communal living by remodeling the senior center (for both the village community center) and elderly housing. Municipalities are similar in their business (is mostly). Senior community center projects can proceed smoothly in the direction of some of the following tips and suggestions to promote. Senior community center should be expanded for 'private room type'. Government must support the operating costs. It will increase employment in rural areas. Senior community center should be 'Home Atmosphere'.

Stream Pilot Project, which began in May 2003 and finished in December 2003, was selected to develop effective methods applicable to nature-like streams. Stream restoration projects aim to maintain or increase ecosystem goods and services while protecting downstream and coastal ecosystems. Fields environmental monitoring such as flow discharge and precipitation were conducted along the Idong stream for amount of channel zone change in 2007. This study selected three monitoring positions to measure the water level and discharge of flowing water. A stage-discharge relation is obtained from direct discharge measurements for three stations by fitting an empirical relationship to the data set. Since discharge measures are made only for low flow conditions, a curve of discharge against stage can then be built by fitting these data with a power curve. And this study used data obtained from floodmark checkup as well as HEC-RAS model to analyze the hydrodynamic characteristics of monitoring sites. Reach-averaged hydraulic parameters for the supply reach were calculated from the small area's HEC-RAS model for Idong stream, and a HEC-RAS model used to analyze hydraulics for a period in 2007, after the stream was considered bank stabilization.

Technology transfer (TT) has been defined as the shared responsibility between the source and the destination for ensuring that technology is accepted and at least understood by someone with the knowledge and resources to apply and/or use the technology. The adoption of TT in construction industries is necessary for economic growth to occur in developing countries such as Thailand. This process should provide numerous benefits for the host sector in areas such as increased productivity, enhancement of product quality, cost savings, improvements in market share and entry to new markets. However, there are many factors, which may impact on the TT process and its subsequent outcomes for Thai construction firms and individuals, including, the transfer environment, learning environment, transferor characteristics and transferee characteristics. The performance and interaction of these enablers will influence the degree of value added to the local construction sectors in areas such as economic advancement, knowledge advancement and project performance. This paper presents a conceptual framework for international TT that accommodates the numerous factors believed to impact on the processes effectiveness. Through a Pilot Study, where 27 industry professionals from Thailand were interviewed, the significant factors which impact on the TT process have been identified along with the strength of interrelationship between individual and groups of factors. Future research seeks to target a greater sample of respondents with the view to validate the conceptual model and apply it on a number of large Thai projects where international TT was incorporated into the project agreement.

Ubiquitous application is in need of high-level technology to meet various requests for ubiquitous service. In order to adopt ubiquitous technology in not only pilot projects but also regional services, many projects like u-City are implemented in and outside the country. RFID has been known as one of the important technology to provide with core benefits of Ubiquitous services. Because each band of RFID technology has merits and demerits concurrently, single-band RFID system has limitations for various RFID services. Thus, we developed dual-band RFID system enable to provide with 13.56MHz and 2.45GHz RFID service at the same time to compensate the shortage of single-band RFID system. Also we have considered the way that the firmware would control signals without collision, studied battery life and range for tag, and made hardware for dual-band RFID service.

The core infra-technology in the ubiquitous era, RFID which has taken action from the public institution with the pilot projects as well as the practical projects is gradually extending its spectrum to the private enterprises. Along with its expansion, the audit required on the RFID-based information system is also growing in the industry. Especially, since RFID-based information systems, especially compared to other information systems, are likely to be exposed to many threats, the security audit for them is being emphasized. This paper suggests security audit checking items for the RFID-based information system, which can be used to perform the efficient security audit. The security audit checking items consist of eight basic checking items, each of which consists of detailed review items and can be applied for each building steps of the system(analysis, design, implementation, testing, and development). Finally, this paper confirmed the efficiency of the security audit checking items proposed in this paper through survey by the experienced auditors and analysis of practical audit cases.

In many construction projects, progress and efficiency are hampered by poor communication of discipline-specific models. For example, architects use 2D or 3D CAD models and builders use CPM diagrams, Gantt charts, and spreadsheets to show their view of the project. Nowadays, advanced computer visualization tools, 4D CAD or VR, can show these disparate models to understand cross-disciplinary impacts of design and construction decisions. In Korea, several leading companies have tried to apply these tools to their pilot projects from the design phase to the maintenance phase. These companies have expected that more project stakeholders could understand a construction schedule more quickly and completely with 4D visualization than with the traditional construction management tools. However, modeling of the 4D CAD or VR can be quite time-consuming and expensive to generate manually and has therefore limited the spread and use of these models. In order to adopt widely those models in construction industry, the areas that those tools could support to take large benefits in diverse functional areas of construction management need to be analyzed. In this study, researchers analyze the usefulness and limitations of the 4D models and VR in the construction industry, develop the strategy of application priority, and improve the 4D modeling method.
