The recent inference of sulfur dioxide (SO2) in the atmosphere of the hot (approximately 1,100 K), Saturn-mass exoplanet WASP-39b from near-infrared JWST observations1–3 suggests that photochemistry is a key process in high-temperature exoplanet atmospheres4. This is because of the low (<1 ppb) abundance of SO2 under thermochemical equilibrium compared with that produced from the photochemistry of H2O and H2S (1–10 ppm)4–9. However, the SO2 inference was made from a single, small molecular feature in the transmission spectrum of WASP-39b at 4.05 μm and, therefore, the detection of other SO2 absorption bands at different wavelengths is needed to better constrain the SO2 abundance. Here we report the detection of SO2 spectral features at 7.7 and 8.5 μm in the 5–12-μm transmission spectrum of WASP-39b measured by the JWST Mid-Infrared Instrument (MIRI) Low Resolution Spectrometer (LRS)10. Our observations suggest an abundance of SO2 of 0.5–25 ppm (1σ range), consistent with previous findings4. As well as SO2, we find broad water-vapour absorption features, as well as an unexplained decrease in the transit depth at wavelengths longer than 10 μm. Fitting the spectrum with a grid of atmospheric forward models, we derive an atmospheric heavy-element content (metallicity) for WASP-39b of approximately 7.1–8.0 times solar and demonstrate that photochemistry shapes the spectra of WASP-39b across a broad wavelength range.

Monitoring sustainable urban development requires comparable geospatial information on cities across several thematic domains. Here we present the first global database combining such information with city extents. The Global Human Settlement Urban Centre Database (GHS-UCDB) is produced by geospatial data integration to characterise more than 10,000 urban centres worldwide. The database is multi-dimensional and multi-temporal, containing 28 variables across five domains and having multitemporal attributes for one or more epochs when the UC are delineated (1975-1990-2000-2015). Delineation of urban centres for the year 2015 is performed via a logic of grid cell population density, population size, and grid cell contiguity defined by the Degree of Urbanisation method. Each of the urban centres has 160 attributes, including a validation assessment. The novel aspects of this database concern the thematic richness and temporal depth of the variables (across geography, socio-economic, environmental, disaster risk reduction, and sustainable development domains) and the type of geo-information provided (location and extent), featuring an overall consistency that allows comparative analyses across locations and time.

Authors: Hanafy Hassan , Tlili Iskander
Published: January 2024

Owing to recent development in the thermal sciences, scientists are focusing towards the wide applications of nanofluids in industrial systems, engineering processes, medical sciences, enhancing the transport sources, energy production etc. In various available studies on nanomaterials, the thermal significance of nanoparticles has been presented in view of constant thermal conductivity and fluid viscosity. However, exponents verify that in many industrial and engineering process, the fluid viscosity and thermal conductivity cannot be treated as a constant. The motivation of current research is to investigates the improved thermal aspects of magnetized Maxwell nanofluid attaining the variable viscosity and thermal conductivity. The nanofluid referred to the suspension of microorganisms to ensure the stability. The insight of heat transfer is predicted under the assumptions of radiated phenomenon. Additionally, the variable thermal conductivity assumptions are encountered to examine the transport phenomenon. Whole investigation is supported with key contribution of convective-Nield boundary conditions. In order to evaluating the numerical computations of problem, a famous shooting technique is utilized. After ensuring the validity of solution, physical assessment of problem is focused. It is claimed that velocity profile boosted due to variable viscosity parameter. A reduction in temperature profile is noted due to thermal relaxation constant.

Published: January 2024

To evaluate the diagnostic performance of dual-layer spectral detector CT for differentiation of breast cancer molecular subtypes. This study was done in a retrospective approach including 104 female patients histopathologically proven to have breast cancer. These patients underwent chest arterial and venous phase dual-layer SDCT. CT values, iodine concentrations (IC)s, and Z-effective (Zeff) values of the lesions and arteries in the same layer were determined for both arterial and venous phases. Parameter values were normalized, and slopes of the spectral curves (λHu) were calculated. Breast cancer biomarkers were also analyzed. Afterward, correlations between the obtained parameters and biomarkers were analyzed. Eventually, the diagnostic performance was assessed using ROC curves. ER or PR-negative patients generally showed significantly higher mean iodine concentrations, CT, and Z-effective values. HER2-positive patients showed significantly higher CTVE, ZeffVE, N-ZeffVE, ICART, ICVE, NICART, NICVE, and λVE. Only ICVEand ZeffVEdiffered significantly between Ki67-positive and negative patients. All parameters showed significant diagnostic value for subtypes except N-ZeffART.Luminal and non-luminal types differed significantly and ROC curves indicated that multi-factors had the best diagnostic efficacy. The dual-layer SDCT distinguishes breast cancer biomarker expression and molecular subtypes. Thus, it can be used for preoperative assessment of breast cancer.
Critical analysis for nonlinear oscillations by least square HPM
Authors: Rafiq Muhammad , Kamran Muhammad , Ahmad Hijaz , Saliu Afis
Published: January 2024

In this study, a novel adapted homotopy perturbation method (HPM) is used to treat the nonlinear phenomena of free vibration in a system with one degree of freedom. This adaptation involves the integration of HPM with a least-squares optimizer, resulting in a hybrid method called the least square homotopy perturbation method (LSHPM). The LSHPM is tested on various nonlinear problems documented in the existing literature. To evaluate the effectiveness of the proposed approach, the identified problems are also tackled using HPM and the MATLAB built-in function bvp5c, and then the results are compared with those obtained using LSHPM. In addition, a comparative analysis is carried out with the results of the AG method as found in the literature. The results show that LSHPM is a reliable and efficient method suitable for solving more complicated initial value problems in the fields of science and engineering.

Published: January 2024

The decongestion ability in response to diuretic treatment plays a crucial role in the treatment of acute heart failure. This effectiveness is evaluated through the assessment of sodium concentration and urine volume, which are also treatment goals themselves. However, the bidirectional interconnection between these factors remains not fully understood. The objective of this study is to provide mechanistic insights into the correlation between spot urine sodium concentrations (UNa+) and urine dilution. This aims to better understand of the decongestive abilities in acute heart failure (AHF). The study was single-center, prospective, conducted on a group of 50 AHF patients. Each participant received a standardized furosemide dose of 1 mg per kg of body weight. Hourly diuresis was measured in the first 6 h of the study, and urine composition was assessed at predefined timepoints. The study group presented the exponential (rather than linear) pattern of relationship between UNa+ and 6-h urine volume, whereas relationship between eGFR and 6-h urine volume was linear (r = 0.61, p < 0.001). The relationship between UNa+ and all other analyzed indices of urine dilution, including the change from baseline in urine creatinine concentration, urine osmolarity, and urine osmolarity corrected for urine sodium, also exhibited an exponential relationship. Patients who were chronically exposed to furosemide demonstrated a significantly lower urine dilution (1.78 [1.18–3.54] vs 11.58 [3.9–17.88]; p < 0.001) in comparison to naïve individuals. In conclusion, it should be noted that in AHF higher UNa+ is associated with disproportionally higher urine dilution, and patients naïve to furosemide have significantly greater ability to dilute urine when compare to chronic furosemide users.
Effect of histidine protonation state on ligand binding at the ATP-binding site of human protein kinase CK2
Authors: Winiewska-Szajewska Maria , Paprocki Daniel , Marzec Ewa , Poznański Jarosław
Published: January 2024

Histidine residues contribute to numerous molecular interactions, owing to their structure with the ionizable aromatic side chain with pKa close to the physiological pH. Herein, we studied how the two histidine residues, His115 and His160 of the catalytic subunit of human protein kinase CK2, affect the binding of the halogenated heterocyclic ligands at the ATP-binding site. Thermodynamic studies on the interaction between five variants of hCK2α (WT protein and four histidine mutants) and three ionizable bromo-benzotriazoles and their conditionally non-ionizable benzimidazole counterparts were performed with nanoDSF, MST, and ITC. The results allowed us to identify the contribution of interactions involving the particular histidine residues to ligand binding. We showed that despite the well-documented hydrogen bonding/salt bridge formation dragging the anionic ligands towards Lys68, the protonated His160 also contributes to the binding of such ligands by long-range electrostatic interactions. Simultaneously, His 115 indirectly affects ligand binding, placing the hinge region in open/closed conformations.

Published: January 2024

At the molecular level, triple-negative breast cancer (TNBC) is frequently categorized as PAM50 basal-like subtype, but despite the advances in molecular analyses, the clinical outcome for these subtypes is uncertain. Long non-coding RNAs (lncRNAs) are master regulators of genes involved in hallmarks of cancer, which makes them suitable biomarkers for breast cancer (BRCA) diagnosis and prognosis. Here, we evaluated the regulatory role of lncRNA SOX9-AS1 in these subtypes. Using the BRCA-TCGA cohort, we observed that SOX9-AS1 was significantly overexpressed in basal-like and TNBC in comparison with other BRCA subtypes. Survival analyzes showed that SOX9-AS1 overexpression was associated with a favorable prognosis in TNBC and basal-like patients. To study the functions of SOX9-AS1, we determined the expression levels in a panel of nine BRCA cell lines finding increased levels in MDA-MB-468 and HCC1187 TNBC. Using subcellular fractionation in these cell lines, we ascertained that SOX9-AS1 was located in the cytoplasmic compartment. In addition, we performed SOX9-AS1 gene silencing using two short-harping constructs, which were transfected in both cell models and performed a genome-wide RNA-seq analysis. Data showed that 351 lncRNAs and 740 mRNAs were differentially expressed in MDA-MB-468 while 56 lncRNAs and 100 mRNAs were modulated in HCC1187 cells (Log2FC < - 1.5 and > 1.5, p.adj value < 0.05). Pathway analysis revealed that the protein-encoding genes potentially regulate lipid metabolic reprogramming, and epithelial–mesenchymal transition (EMT). Expression of lipid metabolic-related genes LIPE, REEP6, GABRE, FBP1, SCD1, UGT2B11, APOC1 was confirmed by RT-qPCR. Functional analysis demonstrated that the knockdown of SOX9-AS1 increases the triglyceride synthesis, cell migration and invasion in both two TNBC cell lines. In conclusion, high SOX9-AS1 expression predicts an improved clinical course in patients, while the loss of SOX9-AS1 expression enhances the aggressiveness of TNBC cells.

Published: January 2024

Due to the complex nature of safety culture and process industries, several factors influence process safety culture. This paper presents a novel framework that combines the hidden content analysis method with Decision Making Trial and Evaluation Laboratory (DEMATEL) and Fuzzy logic to achieve a comprehensive set of influential factors and their relationship. The proposed methodology consists of two primary stages. Firstly, combined methods of literature review and Delphi study were used to identifying influential factors of process safety culture. Secondly, the Fuzzy-DEMATEL approach is employed to quantify and determine the relationships between different influential factors. A diverse pool of experts’ opinions is leveraged to assess the impact of each factor on others and process safety culture. In the first stage, 18 factors identified as influential factors on process safety. The findings of second stage revealed that eight variables were identified as causes, while ten variables were classified as effects. Also, the Organization management's commitment to safety factor had the greatest influence among all of the factors. As well as, the most significant interaction was associated with the risk assessment and management aspect. The integrated approach not only identified the influential factors, but also elucidates the cause-effect relationships among factors. By prioritizing factors and understanding their interconnections, organizations can implement targeted safety measures to improve process safety culture. Its effectiveness in quantifying qualitative data, identifying influential factors, and establishing cause-effect relationships make it a valuable tool for enhancing safety culture in process industries.

Published: January 2024

Several studies have demonstrated that exosomes (Exos) are involved in the regulation of macrophage polarization and osteoclast differentiation. However, the characteristics as well as roles of exosomes from human periodontal ligament cells (hPDLCs-Exos) in M1/M2 macrophage polarization and osteoclast differentiation remain unclear. Here, periodontal ligament cells were successfully extracted by method of improved Type-I collagen enzyme digestion. hPDLCs-Exos were extracted by ultracentrifugation. hPDLCs-Exos were identified by transmission electron microscopy (TEM), nanoparticle tracking analysis (NTA) and western blotting (WB). Osteoclast differentiation was evaluated by real-time quantitative polymerase chain reaction (RT-qPCR), WB and tartrate-resistant acid phosphatase (TRAP) staining. M1/M2 macrophage polarization were evaluated by RT-qPCR and WB. The results showed hPDLCs-Exos promoted osteoclast differentiation and M2 macrophage polarization, but inhibited M1 macrophage polarization. Moreover, M1 macrophages inhibited osteoclast differentiation, whereas M2 macrophages promoted osteoclast differentiation. It has shown that hPDLCs-Exos promoted osteoclast differentiation by inhibiting M1 and promoting M2 macrophage polarization.

Authors: Kolbadinejad Somayeh , Ghaemi Ahad
Published: January 2024

This study is focused on the optimization of effective parameters on Cadmium and Zinc recovery by atmospheric acid leaching of low-grade waste by response surface methodology (RSM) and using the Central Composite Design (CCD) method. The effects of parameters including time (0.5–2.5 h), temperature (40–80 °C), solid/liquid (S/L) (0.05–0.09 g/cc), particle size (174–44 mic), oxygen injection (0–1%) and pH (0.5–4.5) were statistically investigated at 5 surfaces. The sample of low-grade waste used in this study was mainly zinc factory waste. Two quadratic models for the correlation of independent parameters for the maximum recovery were proposed. The properties of waste were evaluated by X-ray diffraction (XRD) and X-ray fluorescence (XRF). Atomic absorption spectroscopy was used to determine the amount of Cadmium and Zinc in the leaching solution. The correlation coefficient (R2) for the predicted and experimental data of Cadmium and Zinc are 0.9837 and 0.9368, respectively. Time, S/L and size were the most effective parameters for the recovery efficiency of cadmium and zinc. 75.05% of Cadmium and 86.13% of Zinc were recovered in optimal conditions of leaching: S/L 0.08, pH 2.5, size 88 µm, 70 °C and 2.5 h. with air injection.

Published: January 2024

X-ray sources have a strong social impact, being implemented for biomedical research, material and environmental sciences. Nowadays, compact and accessible sources are made using lasers. We report evidence of nontrivial spectral-angular correlations in a laser-driven betatron X-ray source. Furthermore, by angularly-resolved spectral measurements, we detect the signature of spatial phase modulations by the electron trajectories. This allows the lateral coherence function to be retrieved, leading to the evaluation of the coherence area of the source, determining its brightness. Finally, the proposed methodology allows the unprecedented reconstruction of the size of the X-ray source and the electron beam emittance in the two main emission planes in a single shot. This information will be of fundamental interest for user applications of new radiation sources.

The Communicative Participation Item Bank–Gender-Diverse Version: Item Bank Calibration and Short Form
Authors: Baylor Carolyn , Bamer Alyssa , Brown Cait , Jin Jingyu Linna , Teixeira Jeffrey , Nuara Michael
Published: January 2024

Purpose:

The purpose of this study was to calibrate an item set for a new version of the Communicative Participation Item Bank (CPIB) specifically for use with gender-diverse clients. This new version contains a new item stem as well as other minor wording changes from the original CPIB in order to be acceptable to gender-diverse respondents.

Method:

Survey data on 47 candidate items were collected from 434 transgender individuals: 219 assigned female at birth (AFAB) and 215 assigned male at birth (AMAB). Item response theory analyses included evaluation of unidimensionality, local dependence, fit to a graded response model, and differential item functioning (DIF) between AFAB and AMAB respondents.

Results:

The original set of 47 items was unidimensional, but 16 items were removed due to local dependence, resulting in a final item bank of 31 items. There was no evidence of DIF between AFAB and AMAB participants. Reliability of the full item bank is good (i.e., > 0.8) between
T
scores of 20 and 76 and high (i.e., > 0.9) between
T
scores of 20 and 68. The short form had good reliability (i.e., > 0.8) between
T
scores of 24 and 64.

Conclusions:

The Communicative Participation Item Bank–Gender-Diverse (CPIB-GD) version provides a new option for person-reported outcome measurement with gender-diverse clients. Clinicians are cautioned to use only the new CPIB-GD with gender-diverse clients, and not the original CPIB due to unacceptable wording in the original version for this population. The original CPIB remains valid and appropriate for the populations for which it was developed.

Published: January 2024

Purpose:

This systematic review represents an update to previous reviews of the literature addressing behavioral management of respiratory/phonatory dysfunction in individuals with dysarthria due to neurodegenerative disease.

Method:

Multiple electronic database searches and hand searches of prominent speech-language pathology journals were conducted in accordance with Preferred Reporting Items for Systematic Reviews and Meta-Analyses standards.

Results:

The search yielded 1,525 articles, from which 88 met inclusion criteria and were reviewed by two blinded co-investigators. A large range of therapeutic approaches have been added to the evidence base since the last review, including expiratory muscle strength training, singing, and computer- and device-driven programs, as well as a variety of treatment modalities, including teletherapy. Evidence for treatment in several different population groups—including cerebellar ataxia, myotonic dystrophy, autosomal recessive spastic ataxia of Charlevoix–Saguenay, Huntington's disease, multiple system atrophy, and Lewy body dementia—were added to the current review. Synthesis of evidence quality provided strong evidence in support of only one behavioral intervention: Lee Silverman Voice Treatment Program (LSVT LOUD) in people with Parkinson's disease. No other treatment approach or population included in this review demonstrated more than limited evidence, reflecting that these approaches/populations require urgent further examination.

Conclusion:

Suggestions about where future research efforts could be significantly strengthened and how clinicians can apply research findings to their practice are provided.

What School-Based Speech-Language Pathologists Need to Know About Pediatric Swallowing and Feeding Development and Disorders
Authors: Garcia Raquel
Published: January 2024

Purpose:

School-based speech-language pathologists are at the frontline for treating children with pediatric feeding disorders (PFDs). Often, speech-language pathologists are the primary allied health professionals who are charged with maximizing safety, supporting nutrition and neurodevelopmental growth. Due to the increasing need for assessment and treatment of PFDs in schools, it is fundamental that PFDs and dysphagia are detected, differentially diagnosed, and addressed to support developing children. This tutorial addresses the anatomy, physiology, and development of functional feeding and swallowing patterns across the spectrum of childhood for both PFDs and dysphagia.

Method:

A clinical expert review of the anatomy, physiology, and development of functional feeding and swallowing patterns in children across the spectrum of childhood will be completed.

Conclusions:

The aim of this tutorial is to support school-based speech-language pathologists in their understanding of the anatomy and physiology of feeding and swallowing. School-based speech-language pathologists should complete this tutorial with an increased understanding and breadth of knowledge related to typical anatomy and physiology versus atypical or disordered presentations. This tutorial would support school-based speech-language pathologists in determining whether a child presents with characteristics of oropharyngeal dysphagia and/or a PFD.

Published: January 2024

Aceh is one of the provinces in Indonesia which has a very large area of rice field production. However, there are many pests that hinder agriculture in Indonesia. One of them is the rice field conch shells which has the potential to cause very high losses to the rice crop harvest. The aim of this research was to determine the ratio of the split tensile strength of concrete using rice field conch shells as a partial replacement for cement and fine sand against normal concrete by 0%, 5%, 10%, and 15%. In addition, it was also seen the effect of immersing concrete specimens using rice field conch shells substitution in tap water and water collected from paddy's farm. This study used the ACI (American Concrete Institute) 211.1-91 and ASTM (American Society for Testing and Materials) methods. The specimens consisted of cylinders with dimensions of 15 cm x 30 cm, totaling 40 specimens with a design concrete compressive strength of 17.00 MPa. The curing of the specimens was carried out using tap water and water collected from paddy's farm for 28 days in the soaking tub. The results showed that 5% substitution of rice field conch shells in cement and fine sand using the tap water immersion method showed a 3% increase in the tensile strength of concrete in comparison with normal concrete. Meanwhile, immersion using the water collected from paddy’s farm method showed a decrease in the value of the split tensile strength of the concrete.

The Aceh region itself has a location that is within the scope of the Sumatran fault, areas on active faults can experience a high possibility of earthquakes. Earthquake epicenters on the mainland can occur due to shifts in the Sumatran fault which is indicated by the number of earthquakes along the fault and generally has shallow depths. The research was conducted to determine the value of the earthquake acceleration on the ground around the East Aceh Alue Genteng bridge. The results of this study found that the magnitude of the earthquake can affect the level of acceleration of the earthquake that occurs, the acceleration of the earthquake increases with the magnitude of the earthquake. Based on the results of calculating the acceleration of the earthquake using magnitude 7, 5 SR-9.3 SR, the earthquake acceleration occurred significantly and continues to increase. Earthquake acceleration data is one of the important data that can be used in earthquake mitigation such as in planning strong building structures that are able to withstand loads caused by earthquakes.

The use of rattan and bamboo fibers increases the compressive strength, tensile strength and improves the ductility of concrete. Shell ash also contains pozzolanic compounds that can improve the properties of concrete. In this study, rattan and bamboo were used as concrete fibers and seashell ash was used as filler. The purpose of this study is to measure the compressive and tensile strength of concrete. In this study, rattan and bamboo fibers were added to the concrete mix with a mix design 25MPa. The additive variation is 0%, 0.5%, 1%, 1.5%, 2%. The results showed that the average compressive strength at 28 days was 0.26.29 MPa, 0.5, 19.71 MPa, 1.21.69 MPa, 1.5, 24.72 MPa and 2.18 MPa. Accordingly, the average tensile strength after 28 days was 0.736 MPa, 2,359 MPa, 2,312 MPa, 2.453 MPa and 2,595 MPa. These results show that the addition of rattan and bamboo fibers to concrete can increase the crack resistance of concrete, while the optimal increase in compressive strength with the addition of rattan fiber is achieved only with the change of 1.5%. This indicates that the addition of 1.5% natural fibers improves the tensile strength of concrete.

Dam construction provides benefits to improve socio-economic status through the availability of food self-sufficiency, irrigation, conservation efforts, hydropower, flood control, and many other benefits to the community around the development. Before the construction process is carried out, a study is needed to present the flow behavior at side spillway of the dam to be safe against hydraulic failure, namely cavitation. The safety evaluation of this dam was carried out on the Krueng Kluet Dam located in South Aceh Regency, Aceh Province, using computational fluid dynamics. The method used in this study is a calculation of analysis from the results of numerical modeling at Krueng Kluet Dam with a discharge flow of Q1000. Cavitation analysis takes flow velocity and pressure data on the side spillway. Results show that crest of the spillway, side channels, and transition channels are safe from cavitation damage. In chute channel, cavitation damage occurs at distances of 450-465 m, 485-505 m, and 560-580 m. This cavitation arises due to a considerable negative static pressure value that can erode the channel surface slowly. A design to prevent cavitation is installing an aerator on chute channel or building a sill on transition channel at a distance of 430 m.

West Aceh district is one of the districts that was affected by the earthquake and tsunami that occurred in 2004. As a district that is in a strong earthquake condition, the aspect of earthquake-resistant buildings is an important object of concern. The Mess Ex KOREM 012 building is one of the buildings that was affected by the 2004 earthquake and tsunami tragedy, resulting in damage to structural elements. There are still very few alternative rescue buildings in Meulaboh, so the former Korem 012 Mess Building is an alternative that can be used to build this building. So this study aims to determine the structural capacity of the Mess Existing Korem 012 building which is intended as an alternative rescue building. This research method uses response spectrum analysis using the Structural Analysis Program (SAP2000) to obtain a structural response to the internal forces of the structure. These data were then processed again with SNI 2847-2019 in order to obtain data on the interaction of forces and moments of the P-MM column ratio and the joint ratio of beam-column relations (HBK). To produce data on the ability of structural elements in accordance with the Requirements for Special Moment-Bearing Frame Systems (SRPMK). The results of the analysis show that in the column area, there is a P-MM condition and the joint ratio HBK > 1. This shows that the ratio of structural capabilities exceeds the capability of the structure, thus the structure of the Mess Ex Korem 012 Building must be repaired to meet the earthquakeresistant building requirements of the SRPMK so it deserves to be used as an alternative rescue building in Meulaboh.

The existing HSD tank F-6302 has suffered damage in the form of corrosion which has caused the plate thickness to decrease. Developments in analysis methods and tank design standards have an effect on determining the stable capacity of the tank, so it is suspected that this tank is unstable. This study aims to analyze the stability of the existing HSD tank F-6302 to seismic response. The analysis was carried out by collecting structural property data of the tank, modelling the tank in FEM with a combination approach of finite element model and auxiliary mass, and evaluating the stability value of the tank using the equation issued by API 650:2020 to assess whether the tank is stable or not. The analysis results confirmed that the tank was unstable to earthquake loading. This is shown by the tank anchorage ratio values of 2.59 for the empty condition and 3.21 for the full condition. Both are greater than the stable limit value of 1.54. In the future, it is recommended to perform tank shell design and anchorage design on the tank.

The earthquake that occurred in Central Sulawesi province on September 28, 2018, devastated parts of Palu City, Sigi Regency, and Donggala Regency. The earthquake and tsunami caused damage to various facilities and infrastructure, resulting in a significant number of casualties. To minimize the risk of casualties during disasters, a rescue strategy is needed, one of which is providing evacuation centers in disaster-prone areas. Therefore, it is necessary to identify which areas can be proposed as temporary evacuation sites during disasters. This research aims to assess the benefits of school infrastructure by examining the suitability of school infrastructure when utilized as temporary evacuation centers. The recommended locations consider the availability of toilets, classrooms, schoolyard area, and service radius. The weighting criteria use Spatial Multi-Criteria Decision Analysis (SMCDA) with the Weighted Overlay method. The analysis is carried out using ArcGIS Pro software, and the weighting of each criterion/layer uses the Analytical Hierarchy Process (AHP) method, considering the criteria of classroom availability, schoolyard area, and service radius. The results of this study indicate that of the 72 schools reviewed, there are 24 schools with a high level of conformity, 19 schools with a moderate level of conformity and 29 schools with a low level of conformity.

The physiological response of motorcyclists, which is substantially correlated with driving stress, can be utilised to assess traffic safety. Heart rate and respiratory rate can be used to measure driver tension using the heart rate variability method. This investigation was conducted in Aceh province along the urban arterial roads Jl. T. Nyak Arief and Jl. T. Muhammad Daud Bereueh. This study seeks to provide the anticipated empirical findings for determining the stress threshold of motorcyclists on Banda Aceh's primary arterial roads. The Polar Vantage V2 Smartwatch Multisport measures the pulse rate and respiratory rate of voluntarily participating motorcycle riders. This research was conducted using direct observation and direct observation related to volunteer travel activities as a sample, with volunteers selected at random and questioned about their willingness to participate. Direct interview surveys with volunteers were used to collect socioeconomic information about volunteers. The Multiple Indicators Multiple Causes (MIMIC) model empirically examined which road conditions and land use variables influence driving tension among motorists. The results revealed that the highest heart rate (HR) was recorded in the commercial land use area, at 94.029 beats per minute, while the highest HR was recorded at road bends, at 94.244 beats per minute. The time domain stress model is influenced by land use variables, with the most significant types of land use being offices and education, with the forming variables consisting of SDNN, RMSSD, and TINN.

In Banda Aceh City, signalized intersections are a strategic approach to mitigate conflicts such as accidents and traffic congestion. This was achieved by efficiently managing the flow of vehicles passing through intersections, enhancing their overall capacity. Currently, the management of signalized intersections in Banda Aceh still adheres to the guidelines stipulated in the 1997 Indonesian Highway Capacity Manual (MKJI 1997). Given the considerable variation in driver behavior and vehicle composition, particularly motorcycles, within Banda Aceh, a need for updated practices arises. Therefore, this research determined the comparison of PCEs values at the initial and saturation time based on the PKJI 2023 and the new calculations. It was conducted at four-legged intersections, namely Pocut Baren, AMD, Lhong Raya, and Jambo Tape. The primary dataset comprised intersections geometry, effective green time, traffic flow composition captured through drone recordings, and signal configurations. Statistical analysis in this research used multiple linear regression analysis to estimate the Passenger Car Unit (PCU) model parameters using video data recorded at the four-legged intersections. The result showed that PCE values for motorcycles during the initial time was 0.16, higher than the average saturation time values of 0.08.
