Oregon’s Coastal Bridge Program was designed to preserve the economic and cultural resources invested in Oregon’s coastal bridges. The Oregon Coast Highway contains a significant concentration of bridges listed on or eligible for the National Historic Register. Many of these reinforced concrete structures are suffering extensive corrosion damage resulting from years of exposure to the marine environment. Oregon has developed this program to evaluate, prioritize, and preserve these magnificent bridges. Preservation of these bridges has relied on the innovative application of cathodic protection technology. This new technology has been applied successfully through a project design and construction process that includes ongoing interaction among design engineers, researchers, construction project management personnel, and contractors.

This paper describes a system; CODESSEAL can provide protection and evaluation to system software. CODESSEAL was designed to protect embedded systems with sufficient expertise and resources to capture attack equipment and manipulator, not only to protect software but also to protect hardware. By using the reconfigurable hardware allows CODESSEAL to provide confidentiality, integrity of security services and a platform-independent program flow without having to redesign the processor. System uses software and data protection technology and designs cycle simulation methods for data analysis. Experimental results show that the protected instructions and data with a high level of safety can be realized a low, which in most cases the performance loss can be reduced to below 10%, so the research of software protection methods of the embedded operating system of hardware compiler has important practical significance.

Ecological environment detection and environmental protection technology becomes an important means to ensure the sustainable development of human beings. Under the premise of the common development of the world’s environmental protection, environmental protection is becoming more and more important. Under the background of the development of science and technology, human beings should also fundamentally solve the ecological environmental protection problem. At the same time, multi-domain ecological environment monitoring data will be used to improve the data processing technology capacity to meet the government’s multi-source control needs and improve the government’s scientific decision-making effect. Starting from the significance of applying ecological environment detection and environmental protection technology, this paper explores and defines the problems existing in the ecological environment detection and environmental protection technology, and puts forward corresponding optimization strategies in combination with big data technology for reference.

Abstract Background Treatment of perforator involving aneurysm (piAN) remains a challenge to open and endovascular neurosurgeons. Our aim is to demonstrate a primary outcome of endovascular therapy for piANs with the use of perforator preservation technologies (PPT) based on a new neuro-interventional classification. Methods The piANs were classified into type I: aneurysm really arises from perforating artery, type II: saccular aneurysm involves perforating arteries arising from its neck (IIa) or dome (IIb), and type III: fusiform aneurysm involves perforating artery. Stent protection technology of PPT was applied in type I and III aneurysms, and coil-basket protection technology in type II aneurysms. An immediate outcome of aneurysmal obliteration after treatment was evaluated (satisfactory obliteration: the saccular aneurysm body is densely embolized (I), leaving a gap in the neck (IIa) or dome (IIb) where the perforating artery arising; fusiform aneurysm is repaired and has a smooth inner wall), and successful perforating artery preservation was defined as keeping the good antegrade flow of those perforators on postoperative angiography. The periprocedural complication was closely monitored, and clinical and angiographic follow-ups were performed. Results Six consecutive piANs (2 ruptured and 4 unruptured; 1 type I, 2 type IIa, 2 type IIb, and 1 type III) in 6 patients (aged from 43 to 66 years; 3 males) underwent endovascular therapy between November 2017 and July 2019. The immediate angiography after treatment showed 6 aneurysms obtained satisfactory obliteration, and all of their perforating arteries were successfully preserved. During clinical follow-up of 13–50 months, no ischemic or hemorrhagic event of the brain occurred in the 6 patients, but has one who developed ischemic event in the territory of involving perforators 4 h after operation and completely resolved within 24 h. Follow-up angiography at 3 to 10M showed patency of the parent artery and perforating arteries of treated aneurysms, with no aneurysmal recurrence. Conclusions Our perforator preservation technologies on the basis of the new neuro-interventional classification seem feasible, safe, and effective in protecting involved perforators while occluding aneurysm.
