Analysis of Data Point Cloud Preprocessing and Feature Angle Detection Algorithm

Background: The two main stages are utilized for feature extraction, from which the first stage consists of a penalty weight to the neighbor graph’s edges. The edge penalty weights are minimized by the neighbor sub-graph extraction to produce the set of feature patterns. For noisy data, the second stage is helpful. Methodology: In order to realize the measurement of the geometric dimensions of the ship block, this paper uses the theory of computer vision and reverse engineering to obtain the data of the segmented-hull with the method of digitizing the physical parts based on the vision, and processes the data by using the relevant knowledge of reverse engineering. Result: The results show that the efficiency of the edge extraction algorithm based on mathematical morphology is 30% higher than that of the mesh generation method. An adaptive corner detection algorithm based on the edge can adaptively determine the size of the support area and accurately detect the corner position. Conclusion: According to the characteristics of the point cloud of ship hull segment data, an adaptive corner detection algorithm based on the edge is adopted to verify its feasibility.

Evaluating the Symmetry in Plantar Pressure Distribution under the Toes during Standing in a Postural Pedobarographic Examination

Pedobarography is a safe, non-invasive diagnostic method that enables estimation of plantar pressure distribution. This article aims to describe the symmetry between right and left toes in the Polish adult population using data obtained during postural pedobarographic examinations. Eighty-two patients, both sexes, with a mean age of 42.12 (range 19–70), without significant pathologies, participated in the study. Plantar pressure was evaluated using a PEL38 pressure plate. The study applies the elements of Cavanagh’s classification to identify the foot sole regions: Hallux, Second Toe and Lateral Toe areas and the entire foot surface. The parameters measured included maximal and average pressures, total support area for each foot, and contact area of the foot with the ground at individual moments of standing. The results showed significantly greater loading under the right Hallux in women. As regards men, higher values in the whole foot pressure distribution were noted on the left side. Plantar pressure distribution does not increase along with the global factors such as age and body mass. The findings suggest that the asymmetry in the morphological structure of the foot does not determine the asymmetry in the plantar pressure distribution. None of the feet studied had full symmetry on the entire surface.

Prenatal Prognostic Factors for Isolated Right Congenital Diaphragmatic Hernia: A Single Center’s Experience

Background: Right-sided congenital diaphragmatic hernia (RCDH) is relatively rare. Clinical data of RCDH, especially with respect to antenatal prediction of neonatal outcome, are lacking. This study aimed to report the treatment outcome of newborn infants with RCDH and to identify prenatal prognostic indicators. Methods: We retrospectively reviewed the medical records of newborn infants with isolated RCDH who were born at a gestational age of ≥35 weeks. We analyzed and compared the clinical and prenatal characteristics including the fetal lung volume, which was measured as the observed-to-expected lung area-to-head circumference ratio (O/E LHR), between the survivors and non-survivors. Results: A total of 24 (70.6%) of 34 patients with isolated RCDH survived to discharge. The O/E LHR was significantly greater in survivors (67.0 ± 19.9) than in non-survivors (42.4 ± 25.0) (P < .05). In multivariate analysis, the O/E LHR was found to be a good predictor of mortality or requirement for extracorporeal membrane oxygenation (ECMO) support (area under the curve [AUC], 0.870; P < .01) and mortality (AUC, 0.789; P < .05). The best O/E LHR cut-off value for predicting mortality and mortality or requirement for ECMO support in isolated RCDH was 47. Conclusions: The survival rate of patients with isolated RCDH was comparable to that of patients with left-sided CDH. The O/E LHR of the contralateral lung was a reliable predictor of short-term postnatal outcome in RCDH.

Evaluation and comparison of oral function after resection of cancer of the upper gingiva in patients who underwent reconstruction surgery versus those treated with a prosthesis

Background We retrospectively analyzed the articulation, mastication, and swallowing function of patients who underwent reconstruction or used a prosthesis after resection of the upper gingiva. Methods This study included patients who underwent resection of cancer of the upper gingiva from January 2014 to December 2018. Articulatory function was evaluated with Hirose’s conversational function evaluation criteria. Mastication function was evaluated with the Yamamoto’s occlusion table. Swallowing function was assessed with the MTF (Method of intake, Time, Food) score. Results The mean articulatory function score was 8 points in the Reconstruction Surgery Group (RSG) and 8.8 points in the Prosthesis Group (PG). The mean mastication function score was 2.8 points in the RSG and 3.3 points in the PG. The mean swallowing function score was M3T4F4 in the RSG and M4T4F4.3 in the PG. Conclusions The prosthesis depends on the remaining occlusal support area. Our study suggest that prosthesis is better indication when there is more than one occlusal support area.

Rockburst simulation using dynamic tests on the support system

Ground support for dynamic conditions must be able to withstand the associated loads and deformations and the support scheme must work as a system. In order to prove the suitability of such support systems with high-tensile steel mesh and bolts and to analyze the bearing behavior of them, a large-scale test setup was commissioned in Walenstadt, Switzerland. On this test rig it is possible to apply large energies on variable ground support systems with variable bolt patterns and meshes with a total support area of 3.6 × 3.6m in a full-scale way. The test site is instrumented by load cells, high-speed video analysis and accelerometers. In this paper the analysis of the load cells, the accelerometers and the high-speed video cameras is given, and results of system tests are discussed.

The Impact of Visual Input and Support Area Manipulation on Postural Control in Subjects after Osteoporotic Vertebral Fracture

Osteoporosis is a prevalent health concern among older adults and is associated with an increased risk of falls that may result in fracture, injury, or even death. Identifying the risk factors for falls and assessing the complexity of postural control within this population is essential for developing effective regimes for fall prevention. The aim of this study was to assess postural control in individuals recovering from osteoporotic vertebral fractures while performing various stability tasks. Seventeen individuals with type II osteoporosis and 17 healthy subjects participated in this study. The study involved maintaining balance while standing barefoot on both feet for 20 s on an Advanced Mechanical Technology Inc. (AMTI) plate, with eyes open, eyes closed, and eyes closed in conjunction with a dual-task. Another three trials lasting 10 s each were undertaken during a single-leg stance under the same conditions. Fall risk was assessed using the Biodex Balance platform. Nonlinear measures were used to assess center of pressure (CoP) dynamics in all trials. Reducing the support area or elimination of the visual control led to increased sample entropy and fractal dimension. Results of the nonlinear measurements indicate that individuals recovering from osteoporotic vertebral fractures are characterized by decreased irregularity, mainly in the medio-lateral direction and reduced complexity.

SPACE CONTROL IN MIXED DENTITION - SPACE MAINTAINERS

Maintaining the child's oral cavity in optimal health by preserving the morpho-functional integrity of primary teeth, given the influence they have on the growth and development of the stomatognathic system is the duty and responsibility of the pedodontist. In addition to prevention, increased attention should be granted to the space control in case of early loss of primary teeth in the support area, recommending the use of space maintainers until the eruption of permanent successors, to intercept the appearance of future anomalies.
