IFC based open BIM has internationally developed as a solution for interoperability problem among different software applications. Despite much interest and effort, the open BIM technologies are rarely introduced to the construction industry and need more technical development for a practical application as well. This research aims to develop automated code checking modules for quality assurance process of BIM data. The research have analyzed domestic regulations focusing on super-tall buildings and developed open BIM-based code checking modules for the evacuation regulations. The modules are able to validate evacuation regulations such as installation of emergency elevator and fire safety zone. The authors expect to improve the process of BIM quality assurance and enhance the quality of BIM data by this research on automated checking system.

The installation of the elevator ARD(Automatic Rescue Device) system has been forced into law in these days in order to safely rescue passengers during power failure. The configuration of the ARD system consists of energy storage device, power converter and control systems. The EDLC(Electric Double Layer Capacitor) are used as energy storage device for rapid charge/discharge purposes. The power conditioning system (PCS) consists of bi-directional converter, 3-phase converter and control system. The dead-beat control system is adopted for most systems however it requires complex mathematical calculations, the high performance microprocessors are mandatory and thus it can be a cause of high manufacturing cost. In this paper the new control method for average current mode control is presented for simple structure. The control algorithm is applied to the single phase system and then expands to three phase system to meet the sysem requirements. The mathematical modeling using average modeling method is presented and analysed by PSIM computer simulation to verifie the validity of the proposed control methods.

Supply Capability of the generator, if the maximum demand occurs, refers to the maximum power that can be stably supplied and it is possible to maintain stable power supply to be greater than actual load. However, unexpected power demand and reduction in supply Capability due to stop of unexpected generator in operation can temporarily make a big chaos in power system. In fact, due to a lack of power supply Capability in the country, enforced emergency load adjustment to the September 15, 2011, the circulation power outage has occurred in several cities. As the result, interrupted operation of the elevator and stopped hospital medical equipment led to a great deal of trouble to people's lives, causing a social problem. At that time, it was found that a failed frequency control because of smaller actual supply Capability than that of predicted. The difference was about 1,170 MW with Gas turbine power plant. By accurately calculating the generator supply capability, we can not only grasp the power reserve rate, but also correspond to the time of power supply instability.

The regional trauma center should be a trauma treatment center equipped with facilities, equipments, and manpower capable of providing optimal treatment from emergency surgery to a severely traumatized patient upon arrival at the hospital. In order to establish a medical system for effective severe diseases, it is necessary to prepare architectural planning guidelines for the regional trauma centers. This study analyzes the connectivity, control, integration, and mean depth of current trauma centers using the convex map of space syntax, And to provide basic data for building for more efficient regional trauma center. The major areas that must be included in the regional trauma center are trauma resuscitation room, trauma operating room, trauma intensive care unit, and trauma general ward. It is necessary to carry out the architectural planning to increase the interconnection of the four areas. Also, the elevator plan for trauma patients should be emphasized. In addition, a regional trauma center should be separated from the existing facility for independent operation. According to the case analysis of the space configuration of the regional trauma center, the location of the operating room is most important considering the connection with each department of the hospital and the treatment flow of the severe trauma patients.

This study evaluated non-liturgical space of catholic churches based on the four principles of universal design; accessible design, supportive design, safety-oriented design, and adaptable design. To design those spaces in terms of supportive design principle, diaper exchanging station needs to be placed in the restroom. Findings of this study are as follows: In terms of accessible design, valid width of entrance door to each room(more than 800mm), installation of elevator, height of riser in the stair, and width of step board were appropriate, but there were many spaces where door sils were not removed. In terms of supportive design, notice board at teacher's room and installation of storage closet, and width of passage to office(more than 1,200mm) were also appropriate, but storage closet at a meeting and prayer room, and space for storing flowers appeared inappropriate. To design those spaces in terms of supportive design principle, diaper exchanging station needs to be placed in the restroom. In terms of safety-oriented design, installation of round-edged furniture, use of non-slip flooring material, installation of safety emergency bell at a restroom, and installation of wall handle were required. In terms of adaptable design, space for wheelchair users at each room, installation of the furniture that can adjust the height, installation of desk with different height at an office, installation of toilet and basin considering children were considered to be necessary.
