Algorithm for dynamic, stability problem analysis and vibration control of laminated composite beams and plates with piezoelectric layers is presented. In addition, numerical calculations, considering the effect of factors on static, dynamic, and stability response of piezoelectric laminated composite beams and plates are also clearly presented. The content of this chapter can equip readers with the knowledge used to calculate the static, dynamic, and vibration control of composite beams, panels made of piezoelectric layers applied in the field different techniques
Advancing Wound Filling Extraction on 3D Faces: A Auto-Segmentation and Wound Face Regeneration Approach
Facial wound segmentation plays a crucial role in preoperative planning and
optimizing patient outcomes in various medical applications. In this paper, we
propose an efficient approach for automating 3D facial wound segmentation using
a two-stream graph convolutional network. Our method leverages the Cir3D-FaIR
dataset and addresses the challenge of data imbalance through extensive
experimentation with different loss functions. To achieve accurate
segmentation, we conducted thorough experiments and selected a high-performing
model from the trained models. The selected model demonstrates exceptional
segmentation performance for complex 3D facial wounds. Furthermore, based on
the segmentation model, we propose an improved approach for extracting 3D
facial wound fillers and compare it to the results of the previous study. Our
method achieved a remarkable accuracy of 0.9999986\% on the test suite,
surpassing the performance of the previous method. From this result, we use 3D
printing technology to illustrate the shape of the wound filling. The outcomes
of this study have significant implications for physicians involved in
preoperative planning and intervention design. By automating facial wound
segmentation and improving the accuracy of wound-filling extraction, our
approach can assist in carefully assessing and optimizing interventions,
leading to enhanced patient outcomes. Additionally, it contributes to advancing
facial reconstruction techniques by utilizing machine learning and 3D
bioprinting for printing skin tissue implants. Our source code is available at

Application of Self-Supervised Learning to MICA Model for Reconstructing Imperfect 3D Facial Structures
In this study, we emphasize the integration of a pre-trained MICA model with
an imperfect face dataset, employing a self-supervised learning approach. We
present an innovative method for regenerating flawed facial structures,
yielding 3D printable outputs that effectively support physicians in their
patient treatment process. Our results highlight the model's capacity for
concealing scars and achieving comprehensive facial reconstructions without
discernible scarring. By capitalizing on pre-trained models and necessitating
only a few hours of supplementary training, our methodology adeptly devises an
optimal model for reconstructing damaged and imperfect facial features.
Harnessing contemporary 3D printing technology, we institute a standardized
protocol for fabricating realistic, camouflaging mask models for patients in a
laboratory environment

Functional-Antioxidant Food
Nowadays, people face many different dangers, such as stress, unsafety food, and environmental pollution, but not everyone suffers. Meanwhile, free radicals are the biggest threat for humans because they lead to over 80 different diseases composed of aging. Free radicals can only be eliminated or minimized with antioxidant foods or antioxidants. The chapter on the functional-antioxidant food presents the antioxidant functional food concept, the classification, the structure, and the extraction process of antioxidant ingredients. Various antioxidant substances such as protein (collagen), polysaccharides (fucoidans, alginates, glucosamines, inulins, laminarins, ulvans, and pectins), and secondary metabolites (polyphenols (phlorotannins, lignins, polyphenols), alkaloids, and flavonoids) also present. The production technology, the mechanism, the opportunity, and the challenge of antioxidants functional food also present in the current chapter. The current chapter also gives the production process of functional-antioxidant food composed of the capsule, the tablet, tube, the pills, the powder, and the effervescent tablet
Extraction of anthocyanins from Butterfly pea (Clitoria ternatea L. Flowers) in Southern Vietnam: Response surface modeling for optimization of the operation conditions
In this paper, the Response Surface Methodology (RSM), in conjunction with Central Composite Design (CCD), was used to optimize the extraction of anthocyanins from Butterfly pea (Clitoria ternatea L.Flowers) cultivated in Southern Vietnam. The effect of extraction temperatures of solvent ethanol (50-70 °C), duration of extraction (40-50 min) and solid-liquid ratios (20:1-30:1) was measured as independent variables on the total extraction anthocyanins in the response function. The highest anthocyanin content of 132.756 mg/L of butterfly pea anthocyanin was collected at the solid liquid ratio of 23:1, extraction time of 46 min, and temperature 60.6°C. Butterfly pea anthocyanins yield detailed significant correlation with high F values, low P values (<0.0001), and desirable determination coefficient (R2 = 0.9994)

A sustainable development indication set plays a very important role for assessing, monitoring the sustainable development status in a region, supporting policy, decision makers to propose confident decisions to control economic, social, and environmental themes toward sustainable developmet. The content, procedure, methodology, and methods to establish the sustainable development indicator set in Tay Nguyen (SDI) were figured out; proposing a list of sustainable development indicators for Tay Nguyen consisting of 77 indicators at regional scale, 70 indicators at provincial scale, 49 indicators at district scale. The SDI could comprehensively show overall development process toward sustainable by 13 themes (economic field - 3 themes; social field - 5 themes; and environmental field - 5 themes). The paper outlined the SDI’s definition and indicated SDI’s significance through linkages between the sustainable development indicators and sustainable development themes.ReferencesLê Thạc Cán, Trần Thùy Chi, Nguyễn Thế Chinh, Nguyễn Viết Thịnh, Ngô Đăng Trí, Nguyễn Thanh Tuấn, Trần Văn Ý và James Hennessy, 2013.
