[Update] One request from the "K&i Web Academy" has been added.

Are you smoothly acquiring units such as CPDS and CPD? KF and Isabou Net are here to assist everyone in the construction and civil engineering industry with obtaining their units!

K&F Corporation and Isabou Net are jointly holding the "K&i Web Academy" (hereinafter referred to as the joint webinar) regularly to support everyone in obtaining CPDS and CPD credits. **Background of the Webinar Business** For civil engineering and construction contractors, it may be required to obtain credits for continuing education as part of the qualification application review for bidding by various regional development bureaus of the Ministry of Land, Infrastructure, Transport and Tourism, as well as some prefectures and municipalities. However, due to the impact of the COVID-19 pandemic, seminars and events that gather people have been canceled or held on a smaller scale. In response to this situation, K&F Corporation has decided to promote the webinar business "KF College" to help those in the construction and civil engineering industry efficiently obtain credits through webinars. Since August 2021, in collaboration with Isabou Net, operated by Godai Development Corporation, we have been hosting various learning webinars aimed at obtaining CPDS and CPD credits for everyone involved in the civil engineering and construction industry, offering webinars that can be attended with reduced costs and time even in the with-COVID era.

**Improvement of Spoofing Prevention Accuracy and Performance** With FaceMe SDK 7.8, we enhance measures against increasingly sophisticated spoofing attacks by improving authentication accuracy and processing speed, thereby increasing the safety and reliability of facial recognition. - IR + RGB Spoofing Prevention: Detection accuracy improved by up to 35%, processing speed improved by up to 15% - 3D Spoofing Prevention: Detection accuracy improved by up to 56.8% for Intel RealSense D415 **Reducing Development Burden with the New Integrated API "FaceMe Authenticator"** We have integrated multiple processes that previously required individual implementation into a single API. Integrated Functions: - Face Detection + Feature Point Extraction + Spoofing Prevention + Authentication Processing Features: - Compatible with Windows / Ubuntu x64 / Android - 2D cameras, 3D depth cameras, and IR + RGB cameras can be used through a single interface - Significantly reduces development burden while maintaining high-accuracy authentication

Crittec Industries Co., Ltd. published a newspaper advertisement (black and white, full-page 15 columns) for the bridge expansion device "Hybrid Joint" in the February 26, 2026 issue of the Sankei Shimbun Tohoku 6 Prefectures edition. In Japan, the number of bridges over 50 years old is rapidly increasing, making the longevity of bridges a critical issue. The expansion devices, which are considered a cause of bridge damage, require high water-tightness and long-term durability. Our expansion device "Hybrid Joint" offers multiple types tailored to different bridge types and conditions. Among them, the "Hybrid Joint 3LII type" has demonstrated a durability of 100 years in fatigue loading tests conducted by a third-party organization. It has successfully passed 12 million cycles of repeated loading at a maximum load of 260 kN, confirming performance equivalent to a 100-year design service life for bridges. We have numerous delivery records in the six Tohoku prefectures and can accommodate a wide range of bridge types, including steel and PC bridges. The special website linked to the advertisement allows for the review of detailed materials and inquiries or requests for documents. Please make use of it for comparing and considering bridge renewal and repair plans. Crittec Industries will continue to contribute to the longevity of bridges nationwide, starting with the Tohoku region.
