A BIM-Based Coordination Support System for Emergency Response
A BIM-Based Coordination Support System for Emergency Response

Abstract: In fire emergencies, timely communication with on-site coordinators and accurate localization of first responders facilitates effective task assignment and resource allocation in harsh, low-visibility environments. Building information modeling (BIM) is widely accepted in the architecture, engineering, and construction industries as a central repository of building information. It could provide both the geometric building data and semantic information; however, the convenient linkage and integration with indoor location technologies for emergency purposes have not been addressed according to the authors’ knowledge.
A stand-alone BIM-based indoor location (BIMIL) framework and portal were designed and tested to enable the automatic extraction, transformation, and visualization of BIM-related data for public safety purposes in this study. Based on current information technology, this research reduces the gap in cross-application by supporting indoor location to overcome the primary shortcoming of existing indoor building models. Eliminating the need for specific software and skill in data processing, this portal will support on-site coordinators’ importation of BIM files, allowing them to convert those files into processed and visualized indoor information containing key yet simplified geometric building data and essential emergency-related information such as fire rating hours, egresses, and hazardous materials. Additionally, the indoor location data can be integrated into a generalized 3D building model to support decision-making activities and management tasks in the field.

Dynamic Exit Signs
Dynamic exit signs are a type of emergency exit signage that uses active illumination and changes in light to draw attention to the nearest exit in case of an emergency. Unlike traditional exit signs that use static or passive lighting to indicate exit locations, dynamic exit signs incorporate lighting systems that respond to specific environmental conditions or power outages, which can help to guide people to safety more efficiently.
There are several types of dynamic exit signs, including:
- Photoluminescent exit signs: These signs absorb and store light energy from ambient sources, such as room lighting or sunlight, and then glow brightly in the dark when the power goes out.
- LED exit signs: These signs use light-emitting diodes (LEDs) to create animated or flashing signs that can better catch people’s attention.
- Electroluminescent exit signs: These signs use electrically charged phosphors to produce a bright, uniform light source that can be more visible in low-light or smoke-filled environments.
Overall, dynamic exit signs are designed to enhance visibility and guide people to safety during an emergency, and they can be an important part of an overall emergency preparedness plan.

Abstract. The SK Telecom Company of South Korea recently introduced the concept of IoST to its business model. The company deployed IoST, which constantly generates data via the LoRa wireless platform. The increase in data rates generated by IoST is escalating exponentially. After attempting to analyze and store the massive volume of IoST data using existing tools and technologies, the South Korean company realized the shortcomings immediately.
The current article addresses some of the issues and presents a big data analytics architecture for its IoST. A system developed using the proposed architecture will be able to analyze and store IoST data efficiently while enabling better decisions. The proposed architecture is composed of four layers, namely the small things layer, infrastructure layer, platform layer, and application layer. Finally, a detailed analysis of a big data implementation of the IoST used to track humidity and temperature via Hadoop is presented as a proof of concept.

“A Prairie Home Companion” is a famous radio variety show created and hosted by Garrison Keillor. The show was known for its mix of humor, music, and storytelling and was broadcast from various venues across the United States. The show often featured live performances and music from various artists and was a cultural staple, particularly in the Midwest.
While Garrison Keillor is best known for his association with “A Prairie Home Companion,” his ties to Macalester College are an important part of his personal and professional history. His experiences at Macalester likely influenced his career in radio and entertainment, and the college takes pride in his achievements as an alumnus.
