Spinal deformity is an abnormality in the spinal curves and can seriously affect the activities of daily life. The conventional way to treat spinal deformities, such as scoliosis, kyphosis, and spondylolisthesis, is to use spinal orthoses (braces). Braces have been used for centuries to apply corrective forces to the spine to treat spinal deformities or to stabilize the spine during postoperative rehabilitation. Braces have not modernized with advancements in technology, and very few braces are equipped with smart sensory design and active actuation. There is a need to enable the orthotists, ergonomics practitioners, and developers to incorporate new technologies into the passive field of bracing. This article presents a review of the conventional passive braces and highlights the advancements in spinal orthoses in terms of improved sensory designs, active actuation mechanisms, and new construction methods (CAD/CAM, three-dimensional (3D) printing). This review includes 26 spinal orthoses, comprised of passive rigid/soft braces, active dynamics braces, and torso training devices for the rehabilitation of the spine.

Purpose. Analysis of methods of manufacturing centrifugal blades by 3D printing methods on the example of a modernized cooling system of the AI-450M engine of the Mi-2MSB helicopter. Research methods: calculation method of finite elements, analytical. Results. Studies have shown that the use of layer-by-layer printing technology of the centrifugal wheel of the cooling system provides the following opportunities and improvements: - reduce the percentage of rejection of finished products by 8–9 times; - reduce material consumption by 300–400 %; - increase the speed of production, experiments and testing the manufacture of working elements through the development of new technologies for rapid production (rapid fabrication); - easy printing of previously “impossible” geometry. The analysis of possible types of manufacturing of  working centrifugal wheel and the calculated estimation of thermodynamic parameters in the course of step-by-step drawing of layers of metal is carried out. The problem of a large percentage of defects in the process of classical-mechanical milling of blades was solved by changing the type of production to additive one. Scientific novelty. In today's world, the spread of CAD / CAM / CAE / PLM technologies and the accumulation of a wide library of materials open up a large number of new and more efficient, in terms of economy and quality, methods of manufacturing components and units. Following the example of such giants in the production of aircraft engines as Rolls-Royce Motor, General Electric and Pratt & Whitney, it is clear that the use and development of the latest methods of three-dimensional printing is appropriate. Practical value. The obtained results are important in the further process of production and modernization ofMi-2 helicopter of all modifications with the latest engines, as well as for projects for the development of helicopter construction in Ukraine - МСБ-2 “Hope”, МСБ -6 “Otaman”, МСБ-8 and others. The ability to increase the efficiency of manufacturing the main working elements - blades allows you to reduce the cost of components, their further repair, operation. The most important factor is to increase reliability, as in the manufacture reduces the likelihood of defects, which will not be detected at the stages of intermediate and final control.

The new and innovative technologies are unprecedentedly improving the level of proficiency in orthodontics in the recent history of this area of expertise. The proliferation of advances, such as self-ligating systems, temporary anchorage devices, shape-memory wires, robotically wire bending, intraoral scanners, cone-beam computed tomography, bring the virtual planning, and confection of dental devices through CAD/CAM systems to the real world. In order to get efficiency and efficacy in orthodontics with these new technologies, we must understand the importance of systemically managed clinical information, medical, and dentistry history of the patients, including the images resources, which ensures the use of a communication that is assisted by the technology, with an interdisciplinary team so that the database is able to help and support the process of therapeutic decision-making. This paper presents the clinical case of a borderline patient for orthognathic surgery who had his final treatment planning supported by these new tools for three-dimensional diagnosis and virtual planning.

Tunable Mechanical Properties

Recent advances in additive manufacturing, specifically direct ink writing (DIW) and ink-jetting, have enabled the production of elastomeric silicone parts with deterministic control over the structure, shape, and mechanical properties. These new technologies offer rapid prototyping advantages and find applications in various fields, including biomedical devices, prosthetics, metamaterials, and soft robotics. Stereolithography (SLA) is a complementary approach with the ability to print with finer features and potentially higher throughput. However, all high-performance silicone elastomers are composites of polysiloxane networks reinforced with particulate filler, and consequently, silicone resins tend to have high viscosities (gel- or paste-like), which complicates or completely inhibits the layer-by-layer recoating process central to most SLA technologies. Herein, the design and build of a digital light projection SLA printer suitable for handling high-viscosity resins is demonstrated. Further, a series of UV-curable silicone resins with thiol-ene crosslinking and reinforced by a combination of fumed silica and MQ resins are also described. The resulting silicone elastomers are shown to have tunable mechanical properties, with 100–350% elongation and ultimate tensile strength from 1 to 2.5 MPa. Three-dimensional printed features of 0.4 mm were achieved, and complexity is demonstrated by octet-truss lattices that display negative stiffness.

Mandibular reconstruction with fibula flap shows a 3D discrepancy between the fibula and the remnant mandible. Eight patients underwent three-dimensional reconstruction of the fibula flap with iliac crest graft and dental implants through virtual surgical planning (VSP), stereolitographic models (STL) and CAD/CAM titanium mesh. Vertical ridge augmentation and horizontal dimensions of the fibula, peri-implant bone resorption of the iliac crest graft, implant success rate and functional and aesthetic results were evaluated. Vertical reconstruction ranged from 13.4 mm to 10.1 mm, with an average of 12.22 mm. Iliac crest graft and titanium mesh were able to preserve the width of the fibula, which ranged from 8.9 mm to 11.7 mm, with an average of 10.1 mm. A total of 38 implants were placed in the new mandible, with an average of 4.75 ± 0.4 implants per patient and an osseointegration success rate of 94.7%. Two implants were lost during the osseointegration period (5.3%). Bone resorption was measured as peri-implant bone resorption at the mesial and distal level of each implant, with a variation between 0.5 mm and 2.4 mm, and with a mean of 1.43 mm. All patients were rehabilitated with a fixed implant prosthesis with good aesthetic and functional results.

A Value

The industry has a relevant spatial and socioeconomic importance in most of the Spanish cities and nowadays is one of the main urban economic activities. However, in many situations, and despite recent advances in the past two decades, industrial heritage is a value that is still not sufficiently widespread in society. The factories, their activity, and their historical evolution are often disconnected and isolated from the daily life of the cities, being quite an unknown aspect for most of the citizens. This contribution presents the result of various experiences of knowledge transmission on the heritage value of industry, through the use of games and storytelling technique as an educational tool and the combination of different technologies (3D modelling, videomapping, virtual reality) as useful tools to spread the explanation of this phenomenon.

This chapter examines Virginia Woolf’s private writings as ethical and political technologies of privacy. In the light of Michel Foucault’s ethics of self-writing, Woolf’s notebooks, letters, and diaries are read as various ‘techniques of living’ rehearsing an elusive tension between immediacy and self-consciousness. The chapter considers in turn the archival impulse of her notebooks, the pragmatics of intimacy at work in her letters, and the aesthetics of daily life outlined in her diaries. Through these daily ‘notes’, Woolf configured various acts of self-making ranging from social critique to psychological immunity. She was also keenly aware of the extent to which her daily ‘scribbling’ or ‘scratching’ was becoming increasingly entangled with new technologies of recording and communication. By relating these archaic media to the social rise of ‘the very private’ in modernity, Woolf mobilized her private writings as untimely techniques of resistance, generating founding, if vulnerable, forms of micro-power.
