[For Civil Engineering and Construction Supervisors] Regarding the Heat Index (WBGT) and Physical Work Intensity

Supervised by Sysmet Co., Ltd. Weather Forecasters! A simple explanation of the Heat Index (WBGT) and physical work intensity!

Thank you for always reading. This time, we will deliver an article related to heatstroke. In the previous article, we explained the heat index (WBGT) as an indicator to measure the risk of heatstroke, stating that high temperature alone does not define "heat." WBGT is an index that quantifies the risk of heatstroke based on "temperature," "humidity," and "radiant heat." However, the factors contributing to heatstroke are not limited to the outside air. The work being performed at that time and the clothing being worn also significantly affect the risk of heatstroke. Therefore, to prevent heatstroke, it is necessary to consider two factors: "correction based on clothing combinations" and "WBGT standard values according to physical work intensity." In this article, we will introduce these two aspects. *For more details, please visit our company website.

The exclusive meteorologist of Sysmet Co., Ltd. will provide easy-to-understand explanations of weather-related terms and the characteristics of weather for each season!

Thank you for always watching. This time, I would like to address the topic of heatstroke. Some of you may be thinking, "What? It's still spring, and we're talking about heatstroke?" However, considering that the number of heatstroke cases tends to increase around May, it's not too early to start preparing now. *For more details, please visit our company website.

Measures for the mandatory implementation of heatstroke prevention at the workplace starting from June 1: Notification of heatstroke information via business chat.

In light of the recent increase in heatstroke-related deaths due to extreme heat, the Ministry of Health, Labour and Welfare has announced the revision of the Occupational Safety and Health Regulations, which will take effect on June 1, 2025. There are three measures that businesses should implement: 1. Establishing a system 2. Creating implementation procedures 3. Informing stakeholders Given the heightened risk of heatstroke that has not been seen before, your company is likely taking careful measures for outdoor work. However, in addition to daily operations, monitoring the heat index (WBGT) and sharing information with all stakeholders can be labor-intensive. This is where we would like to introduce a feature! The natural disaster prevention system ZEROSAI provided by Sysmet supports smooth information sharing by automatically notifying heatstroke information through integration with business chat tools! The compatible business chat tools are "LINEWORKS," "direct," "Wowtalk," and "Microsoft Teams." For more details, please visit our website or feel free to contact us.

The "HA-T Series" is an energy-saving automatic door sensor that opens only for those who want to enter, whether on a busy street or in a narrow passageway. The automatic door opens simply by bringing your hand close, addressing hygiene concerns even in facilities used by a large number of people. Depending on the application and installation location, you can choose between "Non-vision Mount Type/HA-T401" and "Non-vision Built-in Type/HA-T520." 【Recommended for such places!】 ☑ Entrance facing a busy passageway ☑ Presence of counters or signs near the door ☑ Buildings facing narrow passageways ☑ Buildings that prioritize aesthetics ☑ Hospitals and facilities that consider hygiene ☑ Large facilities with many doors 【Features】 ● Adaptable to various door types with four detection spot settings ● Reduces unnecessary opening and closing to minimize power consumption, contributing to energy-saving effects ● Equipped with a light touch function, allowing the door to open and close simply by waving your hand, ensuring hygiene ● Can also be used as a wide detection range non-vision infrared sensor ◎ For more details, please download the materials or contact us.

Our seminar, “Back-Office DX in the Era of Digital Salary Payments,” was featured on HAB News Squash (Hokuriku Asahi Broadcasting) This seminar was co-hosted by Kort Valuta Inc. and Schult Social Insurance & Labor Consultant Office, and was held on January 19, 2026, for companies based in Ishikawa Prefecture https://www.hab.co.jp/news/article/202601217724.php As cashless payments continue to expand, digital salary payments are gaining attention across Japan. The coverage highlights current challenges faced by regional SMEs, including limited information and know-how, as well as key considerations and benefits for implementation. ▶️The seminar video featured in the news is now available on YouTube https://www.youtube.com/watch?v=GlHcFSTrFHM

Starting from January 2026, we are pleased to announce that by linking the measurement data collected on the "Fieldroid Cloud" with the BIM/CIM cloud "KOLC+" provided by Cork Inc., it has become possible to centrally display measurement data summaries on the digital twin. (Examples) Measurement of various environmental data using Cloud Logger LTE Forecasting wind speed, rainfall, and heat index using Signroid 2 Temperature and humidity measurement during concrete curing using Ondroid Slope monitoring using Guraloid Displacement measurement using the shape displacement measurement system "G-Gauge" The data measured by the above services is sent to the cloud, enabling graph displays and alert email notifications. With the implementation of the data linkage function, it is now possible to visualize the latest measurement data from the Fieldroid Cloud on the digital twin constructed in "KOLC+". For more details, please check the content on the linked page.

Regarding the "quotation" used at the forefront of sales activities: "Do we need to save everything when we revise it to Ver.1, Ver.2, etc., every time the amount or specifications change?" "Should we also keep the data from other companies that were not selected in competitive quotations?" Have you ever wondered about these questions? The Electronic Bookkeeping Act strictly demands the "authenticity" of data, but saving all processes is a significant burden for the field. This time, we will clearly explain the boundaries of the preservation obligation in a case study format, incorporating interpretations from the latest National Tax Agency Q&A. *You can read the full text from the note in the "Related Links." [Contents of this article] 1. The boundary of the preservation obligation lies in "sending to external parties." Items sent externally are "generally required to be preserved." Items that have not been sent externally have "no preservation obligation." 2. Judgment from the sending side: "Is it linked to a transaction?" 3. Judgment from the receiving side: "The perspective of the 'Corporate Tax Act' is important." ■ Note! "Version revisions" and "corrections/deletions" are different things. ■ A smart way to ensure reliable "version management." ■ Summary.
