Polymer is one material that can be used as a fixation to repair fractured or broken bones. However, polymers are soft and ductile, so modifying them by adding hydroxyapatite as a filler is necessary. Polyethylene is a high density polymer with more potent material properties to be utilized as a matrix. The PE-HAp composites were synthesized by compacting and heating the composition percentage of Hap 25%, 35% and 45%. Based on the characterization results using XRD, FTIR, and hardness test instruments, it is concluded that the addition of HAp composition results in better composite mechanical properties. The material properties are improving, increasing the hardness value (shore A) by 63 shore A. The hardness value increases because the composite properties are more compact, and the PE matrix physically binds the HAp filler. This is reinforced by XRD and FTIR characterization results, with no new compounds formed and no new molecular vibrational patterns in the FTIR spectrum.

Human breathing rate is an essential marker for assessing one's health, especially regarding respiratory issues. Precise breathing measurements are vital in medicine as they help detect problems early and devise effective treatment plans. The use of fiber optic sensors to monitor breathing offers excellent potential in health monitoring, both medically and independently. Such sensors have advantages such as ease of manufacturing, high sensitivity, compact size, and affordable cost. In this study, a Singlemode-Multimode-Singlemode (SMS) optical fiber-based breathing sensor was designed by fitting it as a belt around the abdomen to measure abdominal breathing. This SMS sensor has variations in multimode length and wavelength used. Tests were conducted in sitting and standing positions, and the results showed the best performance of the SMS sensor at a multimode length of 3.5 cm with an accuracy rate of 99.2525%, linearity of 0.9997, and sensitivity of 2.9725 Hz/dBm. In addition, the standing body position provides 96.5% accuracy with a multimode length of 3.5 cm, while the sitting position provides 96.8% accuracy with a multimode length of 2 cm.

People with spider phobia experience excessive anxiety reactions when exposed to spiders that will interfere with daily life. Diagnosing and measuring anxiety levels in patients with spider phobia is a complex challenge. Conventional diagnosis requires psychological evaluations and clinical interviews that take time and often result in a high degree of subjectivity. Therefore, there is a need for a more objective and efficient approach to measuring anxiety levels in patients. This study performs anxiety level classification based on electrodermal activity, electrocardiogram (ECG) and respiratory signals using the dataset of Arachnophobia subjects. Each raw data is preprocessed using 24 types of features. Feature performance is processed using the recursive feature elimination method. Data processing was performed in 3 anxiety levels (high, medium, low) and two anxiety levels (high, low) with the support vector machine method and hold-out validation method (7:3). The performance of the model is evaluated by showing the accuracy, precision, recall and F1 score values. The polynomial kernel can perform optimal classification and obtain 100% accuracy in 2 classes and three classes with 100% precision, recall, and F1 score values. This result shows excellent potential in measuring anxiety levels that correlate with mental health issues.

Broken nerves could regenerate when exposed to simple injuries by using a nerve conduit that has appropriate physiological and mechanical ability to support the nerves regeneration around the fissure of trauma. One of the biopolymer for the conduit composition is chitosan because it is biocompatible, biodegradable, non-toxic, and has similarity structure as natural glycosaminoglycans. The aim of research is to synthesize chitosan with variation of Degrees of Deacetylation (DD) and characterize the DD influence on mechanical properties and biocompatibility. Research design is prospective observational. Chitosan was treated with a decrease in the DD method and an increase in the temperature with the strength of alkaline solution, which was NaOH solution with concentrations of 5%, 20%, 35%, and 50% within 2 hours with a heating temperature of 95°C. The results of each DD variation were 23.24, 46.55, 53.48, and 55.06. It was characterized by tensile test with tensile strength values of 0.25 - 1.18 MPa. The degradation test results tend to decrease with the increasing concentration of NaOH proving that samples are biodegradable. The surface morphology of samples shows a pore range of 61.52 Î¼m - 220.3 Î¼m. The best result is the chitosan sample with 35% NaOH because due to the tensile characteristic and a pore in accordance with normal standard. Tensile strength is around 0.41 MPa - 3.69 MPa and pore size around 40 Î¼m – 250 Î¼m to accelerate nerve regeneration. The results are expected to provide alternative solution of nerve conduit development for peripheral nerve defects.
