Published: October 2023

A parking slot monitoring system prototype has been produced using the JSN-SR04T ultrasonic sensor and vehicle license plate recognition with ESP32-CAM. The system was created to make it easier for motorists to monitor the availability of parking slots remotely by utilizing Telegram which is connected to the ESP32-CAM module and Arduino Mega 2560. The ultrasonic sensor detects the distance of vehicles entering or exiting the parking lot, then a servo motor opens the entry and exit bars. Vehicle users can monitor the availability of parking slots on the Telegram bot. In each slot there is an ultrasonic sensor that detects the distance so that it can find out whether there is a vehicle in the slot. The test results show that the ultrasonic sensor has an average error percentage of 0.65%. The parking barrier can be opened when the ultrasonic sensor detects the presence of a vehicle at the entrance or exit and the ultrasonic sensor can detect the presence of a vehicle according to the conditions in the slot. The system is equipped with vehicle license plate character recognition using the Optical Character Recognition (OCR) method. Through the ESP32-CAM module camera webserver, the OCR program can detect vehicle plates with the furthest distance of 140 cm using video resolution (400x296) and 300 cm using video resolution (1600x1200). The OCR program can read the vehicle plate characters correctly and the results for the number of characters obtained correspond to the license plate being tested, then the vehicle plate data is stored in the database

Published: October 2023

This research studies the numerical simulation of the finite element method for bird strike using a hemispherical-ended cylinder bird model with varying length-to-diameter (L/D) ratio, namely 1.4; 1.5; 1.6; 1.7; 1.8; 1.9; and 2.0. Birds are modelled with elastic, plastic, and hydrodynamic behaviour. The bird model uses the Coupled Eulerian-Lagrangian (CEL) method with impact speeds of 100 ms-1, 200 ms-1, and 300 ms-1. The simulation results show that the Hugoniot pressure value is around 15-36 times higher than stagnation pressure in L/D 1.4; 14-36 times in L/D 1.5; 13-30 times in L/D 1.6; 12-32 times in L/D 1.7; 12-26 times in L/D 1.8; 13-30 times in L/D 1.9; and 13-29 times in L/D 2.0. It was found that the highest Hugoniot and stagnation pressure were in L/D 1.5 and 1.8, while the lowest Hugoniot and stagnation pressure were in L/D 2.0 and 1.5, respectively. In addition, the error of the numerical results of the average Hugoniot and stagnation pressure value compared to the analytic was 2.9% and 7%, respectively.Â
Perbandingan Profil Vertikal Divergensi dan Vortisitas Model ECMWF dan Luaran SATAID saat Kejadian Hujan di Mamuju
Authors: Asmita Arizka , Malago Jasruddin Daud , Subaer Subaer
Published: October 2023

Divergensi dan vortisitas merupakan parameter meteorologi yang sering digunakan untuk analisis kondisi atmosfer karena berkaitan dengan proses konveksi atau pembentukan awan. Model numerik yang biasa digunakan untuk menampilkan kedua parameter cuaca ini adalah model European Centre for Medium-Range Weather Forecast (ECMWF) dan Satellite Animations and Interactive Diagnosis (SATAID) khususnya saat kejadian cuaca buruk seperti hujan. Penulisan ini mencoba membandingkan nilai divergensi dan vortisitas hasil pengolahan kedua model tersebut pada kejadian hujan yang terjadi di wilayah Kalukku, Mamuju tanggal 24 Oktober 2021 sehingga dapat diketahui model yang baik dalam menampilkan kondisi atmosfer yang berkaitan dengan pembentukan awan saat kejadian hujan khususnya pada musim hujan. Hasil pengolahan data menunjukkan adanya perbedaan yang signifikan yaitu nilai divergensi dan vortisitas model ECMWF lebih tinggi dibandingkan SATAID. Kemudian, pola pergerakan nilai divergensi dan vortisitas secara temporal pada tiap lapisan isobarik berbeda sehingga menyebabkan nilai korelasi yang rendah dan nilai RMSE yang besar antara model ECMWF dan SATAID. Namun, jika dibandingkan dengan hasil pengamatan curah hujan pada Agroclimate Automatic Weather Station (AAWS) Kalukku sebagai acuan proses pembentukan awan terlihat nilai divergensi dan vortisitas model ECMWF lebih fluktuatif sehingga mampu mengidentifikasi potensi pembentukan awan sebelum terjadi hujan dan peluruhan awan setelah terjadi hujan dengan baik pada kasus kejadian hujan di musim hujan.
Digital Communication Recovery Strategy for Business Continuity amid Covid-19: Small and Medium Tourism Enterprises in Gauteng
Authors: Mbatha Blessing
Published: October 2023

This study examined the adoption of digital channels to support business continuity following the outbreak of Covid-19. The population of the study comprised small and medium enterprises (SMEs) as tourism service providers in the City of Tshwane, Gauteng, South Africa. The study employed a quantitative approach and collected data using a self-administered questionnaire. The sample frame was 100 tourism SMEs registered with the Gauteng Tourism Authority, and the sample consisted of 65 business owners selected using purposive sampling. The data were analysed using descriptive statistics. The results show that SMEs have adopted a variety of digital channels such as Skype, MS Teams, Zoom, emails, and so forth. Most of the respondents have shown skills in using digital channels such as Skype, MS Teams, Zoom, emails, and more. The most common applications, such as Skype, MS Teams, Zoom, and emails were used very effectively. The pandemic has substantially increased the diffusion and adoption of collaboration platforms to maintain business productivity and creativity. By linking the workforce beyond the limitations of location or workstation, digital channels allow workers to build communities of interest and collaborate while supporting business continuity. This study targeted only tourism SME service providers in the City of Tshwane. It would have been ideal to include SMEs in other provinces as well, but this would have required more time and resources, which the researcher simply did not have. Therefore, future studies should include SMEs from other provinces to understand how they are using digital channels to support business continuity following the outbreak of Covid-19.
Gerrymandering in Municipal Demarcation Processes in South Africa: Selected Cases of the Collins Chabane and JB Marks Local Municipalities
Authors: Netswera Mpfareleni Mavis , Clapper Valiant
Published: October 2023

This article focuses on political processes, specifically redistricting, which is the political process of redrawing electoral boundaries within which people contest local government elections. It has, however, become common practice for the political party in power to review electoral boundaries in its favour, a practice known as gerrymandering. In South Africa, municipal boundary review, which takes place every five years to either determine new boundaries or re-determine existing boundaries for the purposes of municipal elections, has always given rise to objections. The reasons for such objections range from the lack of public participation in the demarcation process to public perceptions of the value of belonging to one municipality as opposed to another, tribalism, and service delivery concerns. The main findings emanating from the scrutiny of literature on municipal boundary determination protests and the two municipal case studies in South Africa revealed elements of gerrymandering motivated by the political aspirations of those in power.
PROGRAMAS DE INTELIGENCIA ARTIFICIAL (IA): límites en el ámbito jurídico.
Authors: Galindo Fernando
Published: October 2023

El trabajo da cuenta de la relevancia que tiene tomar precauciones ante actitudes que se muestran a favor de señalar que las actividades profesionales de jueces, abogados y profesionales del derecho en general, pueden ser realizadas / ejercidas directa o indirectamente por el propio funcionamiento de las Tecnologías de la Información y la Comunicación (TICs). Ello es así porque este auxilio a las actividades jurídicas (interpretación, aplicación, creación de normas, creación de dogmas y acceso a textos jurídicos), realizadas siempre con relación a textos jurídicos, debe ser regulado precisamente. La reflexión es necesaria porque existen varias propuestas que contradicen, aparentemente, esta idea; es el caso del desarrollo de “programas de IA” que realicen actividades jurídicas profesionales, en cuanto que su posible puesta en acción, constituye una amenaza al funcionamiento del Estado de Derecho.

Ion mobility mass spectrometry unveils conformational effects of drug lead EPI-001 on the intrinsically disordered N-terminal domain of the Androgen Receptor
Authors: Ahmed Ikhlas M. M. , Rofe Adam , Henry Martyn C. , Jamieson Craig , McEwan Iain J. , Beveridge Rebecca
Published: October 2023

Intrinsically disordered proteins (IDPs) are important drug targets as they are integral components of cell signalling networks. Accordingly, their dysregulation is highly implicated in a range of disease states. However, the conformational plasticity of IDPs renders them challenging to characterise both experimentally and theoretically, which is a major bottleneck in the development of small molecule drugs that bind to IDPs and alter how they behave. In relation to this, ion mobility mass spectrometry (IM-MS) is a useful tool in the investigation of IDPs, as it can reveal their conformational preferences when they are ionised from different conditions. It also has the potential to offer important insight to the drug discovery field as it can measure binding stoichiometry, and unveil conformational shifts of IDPs exerted by the binding of small drug-like molecules, which will affect their associated pharmacology. In the current study, we have used IM-MS to investigate the effect of drug lead EPI-001 on the intrinsically disordered N-terminal domain of the Androgen Receptor (AR-NTD). Despite structural heterogeneity rendering the NTD a challenging region of the protein to drug, this domain is responsible for most, if not all, of the transcriptional activity. We quantify the stoichiometry of EPI-001 binding to various constructs that correspond to functional domains of the AR-NTD, and show that it binds to separate constructs containing transactivation unit (TAU)-1 and TAU-5, respectively, and that 1-2 molecules bind to a larger construct containing both sequences. We also identify a conformational shift upon EPI-001 binding to the TAU-5 containing construct, and only to a much lesser extent with TAU-1. This work provides novel insight on the interactions of EPI-001 with the AR-NTD, and the structural alterations that it exerts, and positions IM-MS as an informative tool that will enhance the drugability of IDPs, leading to better therapies.
Novel Computational Chemistry Infrastructure for Simulating Astatide in Water: From Basis Sets to Force Fields Using Particle Swarm Optimization
Authors: Espinosa Kennet , Kananenka Alexei , Rusakov Alexander
Published: October 2023

Using the example of astatine, the heaviest naturally occurring halogen whose isotope At-211 has promising medical applications, we propose a new infrastructure for large-scale computational models of heavy elements with strong relativistic effects. In particular, we focus on developing an accurate force field for At– in water based on reliable relativistic DFT calculations. To ensure such calculations' reliability, we design novel basis sets for relativistic DFT, via the particle swarm optimization algorithm to optimize the coefficients of the new basis sets and the polarization-consistent basis set idea's extension to heavy elements, to eliminate the basis-set error from DFT calculations. The resulting basis sets enable the well-grounded evaluation of relativistic DFT against "gold-standard" CCSD(T) results. Accounting for strong relativistic effects, including spin-orbit interaction, via our redesigned infrastructure, we elucidate a noticeable dissimilarity between At– and I– in halide-water force field parameters, radial distribution functions, diffusion coefficients, and hydration energies. This work establishes the framework for the systematic development of polarization-consistent basis sets for relativistic DFT and accurate force fields for molecular dynamics simulations to be used in large-scale models of complex molecular systems with the elements from the bottom of the periodic table, including actinides and even superheavy elements.

Authors: Carvalho Maria Adriana Santos , Nicolli Aline Andréia , Silva Janaína Costa e , Oliveira Quitéria Costa de Alcantara
Published: October 2023

Os Temas Transversais (TT) são assuntos urgentes no âmbito das diferentes áreas do conhecimento que compõem o currículo da educação básica, pois propõem uma articulação entre os conteúdos escolares e as questões sociais. Eles foram inseridos no currículo nacional quando da publicação dos Parâmetros Curriculares Nacionais (PCN) como alternativa para o desenvolvimento de um ensino mais integrador e contextualizado. Neste estudo, o objetivo foi analisar a produção científica dos Programas de Pós-Graduação stricto sensu no Brasil entre os anos 2017 e 2021, que investigou a abordagem dos Temas Transversais na educação básica. Foram realizadas buscas no Catálogo de Teses e Dissertações da CAPES, utilizando os descritores e as combinações “temas transversais”; “temas transversais” AND “prática docente”; “temas transversais” AND “professores”; e “temas transversais” AND “ensino”, sendo inventariados 42 trabalhos acadêmicos. O panorama traçado demonstrou algumas lacunas em termos de produção sobre o tema. Dentre elas, destacaram-se a distribuição geográfica dos estudos, que se limita, prioritariamente, às regiões Sul e Sudeste do país, e a necessidade de uma maior abrangência em relação aos temas abordados. Concluiu-se que, apesar de mais de duas décadas terem se passado desde a publicação dos PCN e da inclusão dos Temas Transversais no currículo, a proposta de um ensino na perspectiva da transversalidade e interdisciplinaridade, que adota como foco central do trabalho pedagógico temas de relevância social e buscam promover uma educação cidadã, ainda requer muitas reflexões nos campos escolar e acadêmico.
Fatigue life prediction of a Durga flyover bridge at vijayawada using wireless sensors
Authors: V. Guru Rupesh , Vidya B.
Published: October 2023

It is essential to inspect and assess any fatigue damage to the components of a structure in order to determine how long it will last. This is necessary for constructions such as concrete bridges, which are subjected to fluctuating loads with high intensity and frequency. This study presents a computer application method for calculating the fatigue life of the Durga flyover (reinforced concrete) bridge. The damage to bridge components can be evaluated based on the dynamics of the interaction between the bridge and vehicles caused by actual traffic. The computer code initially calculates the fluctuation of stresses caused by the passage of various types of vehicles in a given segment of a bridge. The other module has a continuous set of loads to measure the strains and calculate the stress variations across the section components. The rainflow method is used to count stress cycles owing to the fact that the peak intensities of the stress cycles are not steady, and the appropriate S-N curves are utilized to determine the damage caused by each cycle. In this analysis, the stress range amplitude waveform and fatigue toughness characteristics of bridge elements were employed to systematically detect continuous bridge girder fatigue damage. The most severe flexural stresses induced by vehicles were detected, and a stress-range frequency waveform was created while accounting for the total traffic volume. Linear damage accumulation theory was used to calculate the cumulative damage index and bridge fatigue life. The Miner's rule was used to calculate the overall damage caused by the passage of the vehicles. The major factors affecting the fatigue life are the effects of the span, pavement quality, increase in the speed of operation, weight, and suspension characteristics of the bridge.

Background: Stunting describes the condition of failure to thrive in children under five years old (toddlers) due to chronic malnutrition and recurrent infections, especially in the first 1,000 days of life as a golden period with proper nutrition. This study aimed to examine the effect of prelacteal feeding and vitamin A on the incidence of stunting in children aged 6-59 months using a meta-analysis. Subjects and Method: The meta-analysis was carried out using the PRISMA flowchart and the PICO model. Population: children aged 6-59 months. Intervention: giving prelacteal feeding and vitamin A. Comparison: not giving prelacteal feeding and vitamin A. Outcome: stunting. The online databases used are Google Scholar, ProQuest and Elsevier with the keywords “Stunting” AND “Prelacteal feeding” AND “Vitamin A” AND “Children Aged 6–59 Months” AND “Multivariate” AND “Cross Sectional”. There were 15 cross-sectional studies published in 2013-2023 that met the inclusion criteria. Analysis was performed with RevMan 5.3. Results: A meta-analysis of 15 articles with a cross-sectional study design from different countries, namely Ethiopia, Uganda, Somalia, Indonesia and Sudan in children aged 6-59 months with a total sample of 94,212 research subjects. The results of the meta-analysis showed that there was an effect of not being given prelacteal feeding on the reduced risk of stunting in children aged 6-59 months. Children who were not given prelacteal feeding had 0.57 times the risk of stunting compared to those who were given prelacteal feeding (aOR= 0.57; 95% CI= 0.38 to 0.84; p= 0.005), Children who were not given vitamin A had a risk of being stunted 1.19 times compared to children who were given vitamin A (aOR= 1.19; 95% CI= 1.00 to 1.41; p= 0.050). Conclusion: Children who are not given prelacteal feeding and children who are given vitamin A reduce the risk of stunting in children aged 6-59 months. Keywords: prelacteal feeding, vitamin A, stunting, children aged 6-59 months.

Background: Obesity is a condition that shows an imbalance between height and weight. Obesity in women poses a risk to future pregnancies and their pregnancy outcomes. One of the risks of preg¬nancy in obese women is the birth of babies with excess weight or macrosomia. Excess birth weight can increase the risk of death for both mother and baby. This study aims to examine the effect of obesity in pregnant women on child birth using macrosomia. Subjects and Method: Meta-analysis was performed with the PRISMA flowchart using PubMed, Science Direct, and Google Schoolar databases. Keywords used ((maternal obesity OR obesity in pregnancy) AND (macrosomia OR large for gestational)). There were 11 studies with a cohort design published in 2012-2022 that met the inclusion criteria. Analysis was performed using Revman 5.3. Results: There were 11 articles originating from three continents, namely Asia (2 studies from China, 2 from Saudi Arabia, 1 from Taiwan), the Americas (3 from the United States, 1 from Brazil), and the European continent (1 from Poland and 1 from Spanish). The heterogeneity of effect estimates between primary studies showed I² = 95% (p<0.001), so the analysis used the Random Effect Model (REM). Obese pregnant women had a 2.03 times risk of having a baby with macrosomia compared to pregnant women without obesity (aOR=2.03, 95% CI=1.88 to 2.18; p<0.001). Conclusion: Obesity in pregnant women increases the risk of having a baby with macrosomia. Keywords: maternal obesity, macrosomia.

Background: Exclusive breastfeeding is highly recommended because the nutrition is suitable for babies. However, there are still many babies who do not get exclusive breastfeeding. For this reason, there is a need for innovation that can be used as an effort to increase the production and adequacy of breast milk for breastfeeding mothers with a combination of Accupresure and Moringa oleifera extract. This study aimed to prove the potential of a combination of acupressure and Moringa oleifera extract as an intervention in increasing the production and adequacy of breast milk for breastfeeding mothers. Subjects and Method: This study used quasi experiment and pretest-posttest design with control group conducted at the Kelingi IV/C Health Center, Musi Rawas Regency, from December 2022-January 2023. It consisted of an intervention group consisting of a combination of 2x4 minutes of acupressure and 650 mg of Moringa oleifera extract and a control group of counseling for breastfeeding mothers, namely 40 breastfeeding mothers with babies 0-6 months. The dependent variables were the hormone prolactin and baby's weight. The independent variable was the combination of acupressure and extra Moringa oleifera. The data were analyzed by Wilcoxon. Results: The indicator affected by the combination of acupressure and Moringa oleifera extract was an increase in milk production using the prolactin hormone indicator after intervention (Mean= 304.60; SD=131.22) than before intervention (Mean= 162.85; SD= 140.44), and this was statistically significant (p<0.001). There was an increase in the adequacy of breastfeeding using the infant's weight indicator after intervention (Mean= 5550.00; SD=1240.75) than before intervention (Mean= 5015.00; SD= 1444.87), and this was statistically significant (p=0.030). Conclusion: The combination intervention of 2x4 minutes of acupressure and 650 mg of Moringa oleifera extract for 10 days effectively increases the production and adequacy of breast milk for nursing mothers. Keywords: acupressure, Moringa oleifera, prolactin hormone, baby's weight.

Published: October 2023

Decision making is part of the daily duties of researchers, engineers, and consultants, and taking the right decisions requires quantitative assessment which usually needs data and analysis. In construction industry, data collection or detailed analysis are practically complicated that cannot drive the right results. This fact leads to the common use of qualitative assessment where the numbers are not available, and the evaluation involves various criteria from diverse perspectives. As a Lean tool, Choosing by Advantage (CBA) is used predominately in the Design process. This paper's characteristics and contributions to the existing body of knowledge presents the CBA practice as a qualitative assessment tool in construction phases in the Lean Construction implementation in infrastructure projects, proposing equations through the technique which determines exactly how to assess the percentage advantage for each factor for qualitative factors with different grades or different ranks. The flexibility of CBA as a multicriteria decision-analysis (MCDA) model helped overcome the differences between criteria, categories, and value-based analysis. This paper describes the experience of selecting the option that considers advantages from various criteria in an extensive assessment.

Construction Enterprise Resource Planning (CERP) systems started to infiltrate the construction world after ERPs became crucial in modern enterprises. In simple terms, CERP integrate and keep track of the various processes within construction companies. As a minimum, these possess include management of general contractors, subcontractors, financial work, accounting, payroll, logistics, workflow processes ... data related to different processes are stored within one unique database. Despite this intuitive objective, developing and standardizing CERP systems to fit the needs of all construction companies is not a straightforward course. This research focuses on the development of a framework that integrates the minimum required modules to be included within a CERP, specifically for road and infrastructure construction companies. This objective is achieved based on literature review on CERP despite its shortage, in-depth interviews with construction professionals requiring CERP, and the results of a structured questionnaire filled by CERP users and developers. The developed framework identifies the procurement module linked to the on-site deliveries as the first stone that should be developed and implemented. Then, budgeting and work progress modules must be added. After that, timesheet and equipment follow-up modules need to be implemented. Limitations encountered highlighted the main considerations to be considered in future work such as the cost, the company's size, development and implementation period, and type of work.
L1-L2 congruency as a criterion to identify collocations based on contrastive analysis

In second language learning research, L1-L2 congruency refers to the similarity in form and meaning of the way a word or phrase is said between two languages. If there is low L1-L2 congruency, the learning burden of a word or phrase can be higher, and thus, such items should be focused on more in teaching to help learners avoid errors. For example, an unacceptable structure could be produced when second language learners use direct or literal translation to formulate multiword units (MWUs) in the target language. This study used L1-L2 congruency as a criterion to identify English MWUs with low congruency with their Persian equivalents to create a resource for Persian-speaking English learners. An L1-L2 contrastive analysis was conducted on a list of approximately 11,000 high-frequency MWUs. This list was translated, and the items were given ratings regarding their congruency in Persian. The results revealed that more than 65% of the items examined were incongruent with their word-for-word translations, demonstrating that L1-L2 congruency is a significant factor in selecting MWUs for Persian-speaking English learners. Since focusing on incongruent items may help learners avoid errors, the results of this study can help improve the efficacy of English acquisition by Persian-speaking learners through its identification of particular MWUs that have low congruency between the two languages.
Inspired by Dance: A Future for Kinesiology
Authors: Noton Emily
Published: October 2023

Although the beginning of North American post-secondary level dance education is often traced to physical education, dance programs have since migrated to Fine Arts Faculties. Despite these developments, dance has not entirely disappeared from physical education contexts which are now often under the umbrella of kinesiology. This context can hold new possibilities for dance-inspired movement education.  In this paper, I, as a trained dancer with a research degree in the broad field of kinesiology, reflect upon my experiences of designing an undergraduate dance-inspired movement fundamentals course in a multidisciplinary, research-led Faculty of Kinesiology, Sport, and Recreation in Canada. I further contemplate possible positive implications of including dance research, dance practices, and dance education in this context and the undergraduate kinesiology curriculum.
