From this year, KIGAM, one of Korean government-supported research institutes, has started new national program for digital geologic/natural resources infrastructure building. The goal of this program is to prepare digitally oriented infrastructure for practical digital database building, management, and public services of numerous types of paper maps related to geo-scientific resources or geologic thematic map sets: hydro-geologic map, applied geologic map, geo-chemical map, airborne radiometric/magnetic map, coal geologic map and off-shelf bathymetry map and so forth. As for digital infrastructure, several research issues in this topic are composed of: ISP (Information Strategy Planning), geo-framework modeling of each map set, pilot database building, cyber geo-mineral directory service system, and web based geologic information retrieval system upgrade which services Korean digital geologic maps scaled 1:50K. In this study, UML (Unified Modeling Language)-based data modeling of geo-data sets by and in KIGAM, among them, is mainly discussed, and its results are also presented in the viewpoint of digital geo-modeling ISP. It is expected this model is further progressed with the purpose of being a guidance or framework modeling for geologic thematic mapping and practical database building, as well as other types of national thematic map database building.

As project opportunities for the Architecture, Engineering and Construction (AEC) industry have grown more complex and larger, the utilization of Building Information Modeling (BIM) technologies for three-dimensional (3D) design and simulation practices has been increasing significantly; the typical applications of the BIM technologies include clash detection and design alternative based on 3D planning, which have been expanded over to the technology of construction management in the AEC industry for virtual design and construction. As for now, commercial BIM software has been operated under a single-user environment, which is why initial costs for its introduction are very high. Cloud computing, one of the most promising next-generation Internet technologies, enables simple Internet devices to use services and resources provided with BIM software. Recently in Korea, studies to link between BIM and cloud computing technologies have been directed toward saving costs to build BIM-related infrastructure, and providing various BIM services for small- and medium-sized enterprises (SMEs). This study addressed development of the usage metering functions of BIM software under cloud computing architecture in order to archive and use BIM data and create an optimal revenue structure so that the BIM services may grow spontaneously, considering a demand for cloud resources. For the reason, we surveyed relevant cases, and then analyzed needs and requirements from AEC industry. Based on the relevant cases, customizing for cloud BIM and design for the development was performed. We also surveyed any related-law to support cloud computing-based BIM service. Finally, we proposed herein how to optimally design and develop the usage metering functions of cloud BIM software.

CPR in High-rise building is one of the challenging tasks to 119 paramedics, evacuating patient from the narrow and vertical area. This study was built to compare the method of mechanical CPR and manual CPR is to maximizing on-scene treatment time, and minimizing the hand-off time in cardiac arrest, transporting patient as fast as possible. The electronic data research (Science, Pubmed, Medline, Medline and 55 academic DB interworking) was conducted, and five articles were included by reviewing and excluding through the Covidence program and Review Manager version 5.4(Cochrane Collaboration). OHCA occurring on the higher floor indicates lower in survival. A total studies uniformly reported mechanical CPR is more effective during the high-rise building evacuation, than manual CPR in rate, depth, and hands-on time of chest compression. Use of mechanical CPR device is more suitable in case of High-rise building OHCA to improve the survival rate which is affected by high-quality CPR.

The IB is normally defined in terms of BA, OA, security system, information processing and telecommunications services However, the buildings being already in existence are deficient in two areas. One of these areas is building envelope and plan. The other area is mechanical, electrical and structural systems which do not provide the environmental quality required by IB. Existing technology and design knowledge are available to address these deficiencies. Especially, the office buildings being already in existence must meet IB requirement in order to achieve desirable office environment. They are a building envelope, moisture control, properly-located windows, shafts for duct, telephone and electric closets and acoustical environments. In this paper, a new approach to construct the work scope of remodelling the office building being already existence is described by contrasting the building performance criteria of IB. It concludes by speculating on the consequences of extrapolating the results of study to remodelling the office building being already existence.

Water flow characteristics of an apartment complex consisting of 12 buildings and 635 units in total have been investigated numerically. The complex incorporates two zone booster pump water supply system, and some units have pressure reducing valves in them. Input data to a commercial code Flowmaster7 include survey results on the water usage for the last three years, dimension of the water supply system and its operation condition, etc. Calculated static pressures at the inlet of all units are compared with their design and measured counterparts, and they agree quite well with each other. Then, the pressure distributions and volumetric flow rates at all 635 units are estimated. Flow balancing is also attempted by varying the ratio of angle valve of each unit to improve the non-uniformity of flows.

In recent years, BIM services have been used in many construction projects. However, they are raising the question that there are many differences between what was initially proposed and what was actually done. In the IT sector, a method called as SLA is used to perform an assessment of the services delivered to the IT service project. In this respect, this study intends to introduce this method into building construction projects to use BIM in order to propose evaluation criteria and the evaluation process for SLA-based BIM service. The BIM service assessment process and criteria presented are judged to help introduce consistent and systematic BIM services in construction projects.
