In civil engineering sites such as mountainous areas, construction sites, and river works, it may be necessary to use mats not only on flat surfaces but also on slopes and inclined access roads. Hyper CLT mats are civil engineering materials utilizing wood CLT. In addition to temporary roads, access roads, heavy machinery work yards, and measures against muddy conditions, installation on sloped areas can also be considered after confirming site conditions. They possess surface characteristics unique to wood, creating a different driving environment compared to metal steel plates. On sloped areas, it is important to check the gradient, ground conditions, vehicle weight, and the effects of rain and mud, and to implement anti-shift and securing measures as necessary. The 5×10 mats weigh approximately 230 kg, and the 5×20 mats weigh about 460 kg, making them lightweight and easy to install and remove even with small machinery, as well as easy to handle in narrow spaces. They can also be utilized for safety measures and creative solutions in sloped civil engineering sites, registered as a Ministry of Land, Infrastructure, Transport and Tourism NETIS technology "TH-250021-A."

In civil engineering sites, the size of heavy machinery used for the installation and removal of ground plates also affects construction efficiency and costs. Heavy steel plates may require large machinery, but depending on the site, issues such as workspace and machinery arrangement can arise. Hyper CLT ground plates are civil engineering materials utilizing wood CLT. The 5×10 plate weighs about 230 kg, and the 5×20 plate weighs about 460 kg, making them lightweight and easy to install and remove even with small machinery. They can be widely used as alternatives to steel plates for temporary roads, access routes, heavy machinery work yards, material storage areas, and mud prevention measures. Due to their lightweight nature, they are easy to move and replace on-site, leading to labor savings and reduced work time. Additionally, they offer unique advantages of wood, such as glare reduction, noise suppression, and CO2 fixation. These wooden ground plates are registered as a technology with the Ministry of Land, Infrastructure, Transport and Tourism under NETIS as "TH-250021-A," and can be utilized for construction efficiency, safety measures, environmental considerations, and innovative ideas in public works.

In civil engineering sites, workers often stand for long periods and move repeatedly between material storage areas, break areas, and work locations. Uneven ground or muddy areas can make walking unstable, which may increase the burden on the feet and lower back as workers try to protect their footing. Hyper CLT mats are civil engineering CLT materials that utilize laminated CLT wood. By laying them down in worker pathways, assembly areas, around break areas, and material storage sites, they can reduce ground unevenness and mud, ensuring stable walking paths. Creating a more walkable surface helps reduce the burden on workers' feet and prevent falls. The 5×10 panels weigh approximately 230 kg, and the 5×20 panels weigh about 460 kg, making them lightweight and easy to handle even with small machinery, which also contributes to labor-saving in installation and removal. Additionally, they have unique characteristics of wood, such as glare reduction, noise suppression, and CO2 fixation. These wooden mats are registered as a technology with the Ministry of Land, Infrastructure, Transport and Tourism under NETIS as "TH-250021-A," and can be utilized for safety measures, improving work environments, and innovative ideas in public works.

ANGEWORK Co., Ltd. used the Raspberry Pi 3 Model B (RAM 1GB) from about 10 years ago to implement and optimize generative AI and verify the operation of small LLMs, publishing two technical articles. In the porting of small AI for ESP32, the generation speed was accelerated approximately 6.3 times from 31.22 tok/s to 195.81 tok/s through software optimization. Furthermore, multiple small LLMs were compared, and a model capable of Japanese conversation was confirmed. The approach to design, model selection, and optimization to establish AI in limited CPU and memory environments is introduced, rather than relying solely on expensive GPUs and the latest equipment. This content is aimed at corporate representatives and engineers considering AI utilization in existing devices, IoT, manufacturing equipment, and closed environments.
