The differences between this study and previous studies are as follows. First, by building a cloud-based system using IoT technology, the system was built to monitor the status of buildings in real time from anywhere with an internet connection. Second, a model for predicting the future was developed using artificial intelligence (LSTM) and statistical (ARIMA) methods for the measured time series sensor data, and the effectiveness of the proposed prediction model was experimentally verified using a scaled-down building model. Third, a method to analyze the condition of a building more three-dimensionally by visualizing the structural deformation of a building by convergence of multiple sensor data was proposed, and the effectiveness of the proposed method was demonstrated through the case of an actual earthquake-damaged building.

In Regarding urban geo-spatial information visualization in this study, visualization of physical attribute information is mostly related to the representation of spatial domain and physical objects, and visualization of non-physical attribute information has to do with visualizing citizens and their activity information in the physical environment. In particular, a citizen, one of the non-physical information attributes, is characterized by a constant mobility in the physical environment, and thus visualization of his/her activity information is vital in conveying information because this information may not be depicted with any given, fixed figures. In consideration of this difficulty, this study integrates interrelationship among urban space, human needs, social relations, and lifestyles into a 'high-tech' service where experience in time and space is possible. To analyze the web-service and visualization cases, the study has selected visualization indicators consisting of information representation objective, information representation means, and information representation result. The results of the case analysis through specific indicators set a range in information representation objective, means, and result, thereby forming a user-friendly environment in which representational results are readily available to users, and ultimately expanding the users' selection range coming with a variety of options. This study also assumes that a wide range of service provision is needed to reflect users' needs in developing urban geo-spatial service model, and the display of its results should visualize users' satisfaction to construct the best information needed to users.

This study is centered on the combined use of LiDAR(Light Detection and Ranging) and AR(Augmented Reality) technologies during vertical and horizontal frame measurements in construction projects. The intention is to enhance the quality control procedure, elevate accuracy, and curtail manual labor along with time expenditure. Present methods for accuracy inspection in frame construction often grapple with reliability concerns due to subjective interpretation and the scope for human error. This research recommends the application of LiDAR and AR technologies to counter these issues and augment the efficiency of the inspection process, along with facilitating the dissemination of results. The suggested technique involves the collection of 3D point cloud data of the frame utilizing LiDAR and leveraging this data for checks on construction accuracy. Furthermore, the inspection outcomes are fed into a BIM (Building Information Modeling) model, and the results are visualized via AR. Upon juxtaposing this methodology with the current approach, it is evident that it offers benefits in terms of objective inspection, speed, precise result sharing, and potential enhancements to the overall quality and productivity of construction projects.

Human tend to rely their information about the size of a space on vision. However, it might be a common experience to perceive a certain difference in spaces without any visual difference, in such spaces as rooms for music performance, multimedia environments with multiple sound sources, and car cabins, where auditory experiences have a certain importance. In the present work, apparent auditory room size was measured at different positions in a room through a series of listening experiments. Also, measurement of room acoustic parameters was carried out and their relationships with perceived auditory room size were analyzed. The results suggest that apparent auditory room sizes were largely dependent on musical clarity, distance between a source and a receiver, and sound pressure level at the listening position. Also, the results from acoustic preference test suggest that smaller apparent room sizes were preferred for listening to orchestral, cello and flute music. The relationship between apparent auditory room size and vocal music was found to be statistically insignificant.

Fire accidents in buildings are reported more frequently nowadays. Existing building fire accidents can lead to large-scale accidents as damage to human and physical resources increases over time, so it is necessary to quickly find ways to suppress fires and rescue them. Currently, more attention is being paid to new buildings than the existing buildings. In addition, fire information can not be captured in a real time basis for the buildings. In line with the demands of this technology, this study presents a quick and systematic fire management method to minimize damage caused by fire in buildings. As a way to achieve the purpose of the study, ArduinoTM sensors and ExcelTM and RevitTM-DynamoTM tools have been combined to develop a new fire information management system and develop a real-time 3D visualization model. It is expected to contribute to the real-time smart fire management system by proposing a fire management application as a way to utilize it in the future.

3D VR modeling data can be used for powerful expression in construction, because it gives help to navigate a construction in 3D space easily. But the current status of VR technique visualizes only an external shape of a construction. A construction has not only its external shape data but also its constructive information. The constructive information is very important and can be expressed as the process of construction and deconstruction. Thus we research on recording and replay interface to manipulate 3D structured objects for the process of construction and deconstruction.

The planning stage of an architectural project has much more significant effects on the cost or outcome of the project than other stages of the project. In addition, the importance of architectural planning has been further increasing according to the recent trend of construction projects becoming larger in scale and more complex. In spite of this, the current situation is that the planning stage work is not being systematically managed. Accordingly, the purpose of this study was to develop a BIM-based simulation system for providing support during architectural planning stage such as spatial planning & review, cost review, project owner requirements management, etc. It is easy to review various alternatives using this system that allows not only the modeling of space object modeling but also the instantaneous review of spatial area & layout, cost, etc. based on object information. In addition, it can be used as a communication tool with the project owner as it provides the visualized information and quantitative data of the building model, and the information created through this system can be delivered to the following stage for usage. It is thought that using this system, the entire project work including the architectural planning stage can be supported and even contributing to the advancement of architectural process.
