An article about the IoT earthquake observation service was published in the Construction Communication News on April 11.

Simple estimation of earthquake damage to mid-rise buildings! Guidance on the necessity of inspections!

**Overview** The Earthquake Safety Chart estimates the damage status of three categories: "structural elements," "exterior walls and interior finishes," and "furniture and fixtures," based on the measured results of seismic sensors installed on the first and upper floors of the target building, specifically the "maximum inter-story drift angle" and "maximum acceleration." It also provides guidance on the necessity of inspections. **Target Buildings** 1 to 8-story steel structures (S) and 3 to 8-story reinforced concrete (RC) or steel-reinforced concrete (SRC) structures. **Provided Price** Free of charge, provided that the IoT earthquake observation service (with two seismic sensors) is utilized. **Utilization Scene** It is intended for use in initial response during earthquakes in mid- to low-rise buildings and offices.

We have introduced our commercial aroma diffuser "Majesta Fragrance" at a karaoke bar located in the city. The model we installed is [MF-02S]. From the moment customers open the door, a gentle fragrance spreads throughout the store, enhancing the atmosphere. We hope to create a memorable store that customers will want to visit again through the use of fragrance. Majesta Fragrance is available for a free trial installation exclusively in the Kanto area. If you are interested in our fragrance services, please feel free to contact us.

We have introduced our Majesta Fragrance in the restrooms of a company located in the city. The model we implemented is the compact-sized MFmini. By adding fragrance to the clean space, we have created an environment where users can spend their time more comfortably. The restroom, which is used daily, has become a more pleasant and high-quality space.

Thank you very much for always using Majesta Fragrance. Our company will be open as usual during the Obon period. Please feel free to contact us for inquiries about scent arrangements or the introduction of commercial aroma diffusers.

High Strength, Low Cost: The Economic Advantages of Carbon Steel Frames Carbon steel is inherently strong, and this high structural strength ensures stable wind resistance while allowing for a simple support structure, reducing the need for extra components. This also lowers the wear rate during transportation, enabling further savings in material costs and installation expenses. Transportation and Construction: Streamlining the Entire Project The advantages of carbon steel frames are also evident in the transportation and construction phases. Standardized designs simplify on-site installation and shorten construction periods. For example, carbon steel frames can be packaged using a combination of wooden sticks and iron ties, improving unloading efficiency and increasing transport volume. This reduces construction time and labor costs, distributing the overall burden of the project across all stages. Technological Innovation: Breakthroughs in Corrosion Resistance With the evolution of material technology, the corrosion treatment of carbon steel frames has also significantly advanced. Grace Solar has adapted to the technological trends in process development, and all current carbon steel frames utilize AlMgZn coating. At the same time, to meet the special requirements of each project, our company offers custom options for hot-dip galvanizing.
