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.

"Somehow inconvenient" will inevitably become a "visible cost" if left unattended. When small inconveniences and anxieties accumulate in the HR and general affairs field, they manifest as a significant burden during peak times at the end and beginning of the month. This time, we will introduce the process of a fresh food sales company with about 200 employees that articulated this vague discomfort and took the first step. When we articulate "somehow inconvenient"... The company's challenges were clear: 1) Managing attendance with paper time cards requires a lot of effort for aggregation and Excel transcription. 2) Transcription errors undermine the reliability of payroll data, and inquiries about remaining paid leave require opening Excel each time for confirmation, increasing the workload on-site. 3) Low IT literacy creates psychological resistance to the introduction of new systems, acting as a barrier. Information from iBP To organize "where to start," we first clarified priorities. The conclusion is simple. You can read the continuation without entering personal information.
