Japan is one of the top 10 countries in the world with frequent earthquakes. The 2020 White Paper on Land, Infrastructure, Transport and Tourism has also reported an increase in the probability of major earthquakes occurring. Regarding the Nankai Trough earthquake, the probability of an earthquake with a magnitude of 8 to 9 occurring within the next 30 years is estimated to be 70 to 80%. At Hotron, we recommend the introduction of seismic devices for earthquake countermeasures in buildings and equipment. The seismic device 'HK-2' is a product that automatically performs various controls that have been pre-set when it detects strong shaking equivalent to a seismic intensity of 5 lower or higher. For example, it can automatically execute actions such as: "Open automatic doors and gates to secure evacuation routes and access for emergency vehicles" "Transmit signals to the control room and stop facility equipment" "Unlock the keys to locked lockers" "Automatically play voice guidance" For more details, please download the materials or contact us.

Do you have any concerns or requests regarding wired bed exit sensors? × Tangling or tripping over wired cables × Cable disconnection or damage × Worrying about forgetting to turn the switch back on after temporarily stopping the sensor. × Wanting to be notified of bed exits even from a location far from the nurse call outlet. Such concerns can be resolved simply by connecting our wireless nurse call linked set to the sensor! Our wireless nurse call linked set allows you to connect bed exit sensors like "Ugo-kun," "Foldable Thin Matta-kun," "Ayumi-chan," and "Just Place Pole-kun" to transmitters and receivers, reducing wiring around the bed area, alleviating concerns about tripping or falling due to cables, and contributing to a tidier work environment. Furthermore, it enables the use of bed exit sensors even from locations far from the nurse call outlet, allowing for more flexible equipment placement.

SBS Marketing Co., Ltd., which provides consulting services related to marketing, sales promotion, and customer acquisition mainly in the BtoB (business-to-business) sector based on practical experience in support companies and business companies, has published a page titled "Is it perceived extremely as 'zero or one hundred' or 'white or black'!? 'Zero-Sum Bias'" on December 23, 2025 (Tuesday). The 'Zero-Sum Bias' is a way of thinking that judges things as 'white or black', 'win or lose', 'zero or one hundred', or 'gain or loss', narrowing down choices to 'extreme two options'. The page explains the mechanisms behind its occurrence and methods to overcome it. (Page Overview: Excerpts) ■ What is 'Zero-Sum Bias'? ■ Negative effects caused by 'Zero-Sum Bias' ■ Why does 'Zero-Sum Bias' occur? ■ How to overcome 'Zero-Sum Bias'?
