Summary: With the increasing popularity of online shopping, the practice of buying shoes without trying them on has become more common. This has resulted in a higher rate of product returns, leading to significant financial and ecological burdens. In order to address this issue, this paper provides an overview of the current measurement methods available on the market for determining foot size. The different commercial systems are categorized based on their underlying technology, and the most promising methods are implemented and tested. The results of these tests are compared to identify the strengths and weaknesses of each technology. The study finds that measurement using a Time-of-Flight (ToF) sensor is currently the most robust, easiest, and among the most accurate methods for measuring foot dimensions.

Summary: This systematic review aimed to identify podometric measurement tools used to classify footprints in individuals with Down syndrome (DS). The study found a lack of research on the specific morphotype features of feet in DS subjects, indicating a need for further investigation into the reliability and validity of footprint measurement methods for clinical classification. The footprint measurement tools identified in the study, such as podoscope and 3D scanner, can play a crucial role in early diagnosis of foot abnormalities and improving the quality of life for DS patients.

Summary: This study found that both body mass index and arch height were associated with specific ankle and knee joint mechanics during walking in healthy young adults. Higher BMI was linked to greater peak internal ankle plantar-flexion moment, while lower arch height was linked to greater peak internal ankle eversion and abduction moments, as well as peak internal knee abduction moment.

Summary: This study evaluated the validity and reliability of three-dimensional joint kinematic outcomes obtained by IMUs for runners. The results showed high reliability in the sagittal plane, especially for RFS runners, while caution is needed when using IMUs data in the frontal and transverse planes.

Summary: The purpose of this clinical study was to compare the color difference among three different shade selection methods during the fabrication of ceramic crowns. The results showed that digital shade selection with photographs acquired using a digital camera and a smartphone with a light-correcting device had smaller color differences compared to visual shade selection.

Summary: This study investigated the color accuracy of digital photographs taken by a single-lens reflex (SLR) camera and a smartphone camera in a clinical setting. The results showed that calibrating the white balance for the SLR camera can improve color accuracy, while using a polarizer does not significantly improve color accuracy. A smartphone camera with an external light source can serve as a viable alternative.

Summary: Assessment of progress in chronic wound healing is crucial, with wound healing societies recommending using the rate in wound surface area reduction as a marker of therapy effectiveness. Different methods for wound surface area measurements exist, varying in technology, accuracy, and level of contact with the patient's skin or wound. Advanced techniques range from linear measurements to 3D analysis of skin curvature.

Summary: This study compares the application of multiple stripe analysis (MSA), cloud analysis (CLA), and incremental dynamic analysis (IDA) methods in the seismic fragility analysis of arch dams. A comprehensive dam-reservoir-foundation rock system is used as a numerical example, considering factors such as the opening of contraction joints, nonlinearity of dam concrete and foundation rock, radiation damping effect of semi-unbounded foundation, and compressibility of reservoir water. 225, 80, and 15 earthquake records are selected for MSA, CLA, and IDA, respectively. The results show that MSA provides satisfactory fragility analysis, while CLA and IDA have assumptions that may lead to deviations. Therefore, MSA is considered the most reliable method for the fragility analysis of arch dams. It is also found that the choice of demand level affects the reliability of fragility curves, and the effect of material uncertainty on dam fragility is not significant.

Summary: This paper proposes an automatic spacer bar segmentation algorithm, CM-Mask-RCNN, which combines the CAB attention mechanism and MHSA self-attention mechanism to automatically extract spacer bars and calculate center coordinates. By using UAV inspection video data and classical algorithms, arc sag measurement with low cost and high efficiency is achieved. Experimental results show that the CM-Mask-RCNN algorithm achieves better performance compared to other algorithms, with an AP index of 73.40%. The fused CAB and MHSA attention mechanisms significantly improve the segmentation performance of the model, with an AP improvement of 2.24%. Experimental measurements on 10 different transmission lines validate the effectiveness of the proposed arc sag measurement method.

Summary: Public participation is crucial for promoting the quality of the built environment. This research compares a digital twin park and a physical replica in a participatory workshop using Nancuiping park in China as a case study. The results suggest that the digital twin model provides better interactivity and efficient scene simulation and visualization quality, while the physical replica is easier to use. Age is identified as a barrier to promoting digital twins for older participants, while younger and well-educated participants are attracted to the highly interactive features and high-resolution visualization capability of the digital twin model.

Summary: Ankle-foot orthoses (AFOs) are braces worn to support ankle motion, with rotational stiffness being a key mechanical property that affects gait biomechanics. The AFO Stiffness Measurement Apparatus (SMApp) was designed to measure torque and angle as an AFO moves through a range of motion, providing high reliability for all measured AFO properties. The SMApp can be used for AFO material fatigue testing, validating finite element models, and evaluating speed effects on AFO properties in future studies.

Summary: This study evaluated the effect of different data acquisition methods on the trueness and precision of mandibular complete-arch implant scans. The results showed that the data acquisition methods significantly affected the surface and angular deviations of the scans. The tested data acquisition methods were found to be feasible for digitizing mandibular complete-arch implants, considering the deviations within the previously reported thresholds and the high precision of scans. However, the frameworks fabricated with the direct digital workflow involving scans of the stereoscopic camera might require more adjustments.
