IMPLICATIONS OF CONSTRUCTIVISM LEARNING THEORY ON STUDENTS' CRITICAL THINKING SKILLS: A THEORETICAL STUDY
Authors: Hidayatullah Umar Hasan
Published: August 2024

Education is an important foundation in the development of individuals and society. In the challenging modern era, the education system must be able to develop critical thinking skills in students. Constructivism learning theory, which emphasizes students' active role in constructing knowledge, offers a relevant approach for this purpose. This study explores the implications of applying constructivism theory to the development of student's critical thinking skills through a qualitative method with theoretical review and literature study. The findings show that problem-based learning strategies, group discussions, and collaborative projects are effective in improving critical thinking skills. However, the implementation of this theory varies depending on the educational context and teacher readiness. In developed countries, the implementation of constructivism is more successful than in developing countries, which face challenges such as lack of resources and teacher training. The results of this study offer practical guidance for educators and policymakers in designing curricula that are responsive to student's needs, as well as making a significant contribution to the education literature.

The study of Nahwu, a branch of Arabic grammar, focuses on changes in word endings related to i'rab (inflection) and bina (construction), as well as sentence structure. Within Nahwu, the concept of tawabi’ refers to words that follow another in agreement with case, definiteness, and other grammatical aspects. Tawabi’ is categorized into na’at (adjective), taukid (emphasis), badal (substitute), and athaf (conjunction). This research specifically analyzes na’at and its types in the book "Washôyâ Al-abâ Lil Abnâ" by Muhammad Syakir Al-Iskandarî, which is widely used in Islamic educational institutions. The objectives are to identify and categorize the types of na’at in the text. Using a literature research method, the study employs documentation and data analysis based on the Miles and Huberman theory, involving data restriction, grouping, and presentation. The findings reveal 97 instances of na’at in the book, with 96 being na’at haqiqi (direct adjectives) and 1 being na’at sababi (causal adjective). The types of na’at identified include mufrod (single words), jumlah (sentences, both nominal and verbal), and syibhul jumlah (prepositional phrases), with the majority being na’at haqiqi mufrod. The study suggests further research to deepen the exploration of tawabi’, particularly na’at.

Published: August 2024

Computational thinking skills can help students in solving problems. Teaching materials such as student worksheets are still limited to textbooks. Physics learning can use GeoGebra to help visualise phenomena. This study aims to analyse the computational thinking ability of students through the implementation of GeoGebra integrated student worksheets on motion material on indicators of abstraction, decomposition, algorithm thinking, and generalisation. This type of research is a combination of quantitative and qualitative. Quantitative data analysis uses formula calculations to assess student worksheets. Meanwhile, qualitative data analysis uses an interactive approach by Miles and Huberman. The results showed that the students' computational thinking ability on the abstraction indicator of as many as 25 people, decomposition on as many as 20 people, and algorithmic thinking on as many as 25 people are classified as very good. This is indicated by students being able to determine important information, identify problems to be simpler, and explain steps systematically. In the generalisation indicator, students' average computational thinking ability is in a good category. In short, most students in computational thinking skills on abstraction, decomposition, and algorithm thinking are classified as very good, while the generalisation indicator is classified as good.

Published: August 2024

This research aims to identify a decrease in students' misconceptions about dynamic fluid material after learning is implemented Three Stay Two Stray (TSTS) with the help of ARaRaT in experimental and learning classes and TSTS in the control class. This research uses mixed methods with a research design embedded in an experimental design. The research sample involved 65 students (22 male and 43 female) in class XI MIPA at one of the public high schools in Cimahi City. The technique for collecting data on students' misconceptions used the test instrument Four-Tier Fluid Dynamic Concept (FT-FDC), which consists of 10 questions that are analyzed using the reducing quantity misconceptions equation to see the decrease in the number of students' misconceptions after being given treatment. The results of the data analysis in the experimental class showed a change in the percentage of students experiencing misconceptions from 38.8% to 10%, with an average decrease of 28.8%. Meanwhile, the percentage change in the number of students' misconceptions in the control class was obtained from 36.1% to 23.9%, with an average percentage decrease of 12.2%. This research implies that students become more skilful in conducting experiments with the help of ARaRaT and better understand concepts that are not only in the form of verbal statements but with various forms of representation of images, graphs, tables, mathematical equations, and even 3D media with the help of Augmented Reality. Thus, implementing TSTS learning assisted by ARaRaT can be an alternative to physics learning to reduce students' misconceptions.

Authors: Rahmanniar Revista Rizky , Supriana Edi , Purwaningsih Endang
Published: August 2024

The student worksheets development activity was carried out because its use in learning was still relatively simple, thus influencing students' enthusiasm for mastering concepts and developing creative thinking skills. This is due to limited teacher innovation in developing teaching materials that suit student needs. This research aims to determine the feasibility of project-based student worksheets learning and its influence on mastery and creative thinking skills. The feasibility of Projrct-based Learning (PjBL)-based worksheets learning was measured using the validation results of media experts, teaching module experts, and field practice experts, with scores of 78.45%, 86.11%, and 92.70%, respectively. Mastery of concepts and creative thinking abilities were measured using the Independent Sample T-test based on pretest and post-test data. The implementation results show an increase in mastery of concepts and creative thinking skills in classes that implement PjBL-based worksheets compared to classes that do not implement PjBL-based worksheets. The values are 0.003 and 0.032, respectively (significance level <0.05).

The Effect of The Audit Committee on The Voluntary Risk Disclosure In Jordanian Commercial banks: the moderating role of Family Ownership .
Authors: Maani Abdullah , Buraik Ola , Al-amarneh Asmaa , Almashaqbeh Mohmmed
Published: August 2024

Corporate governance has received increasing attention from practitioners and politicians after the collapse of large companies due to accounting errors and failure to disclose information that reflects the true financial condition of companies. Voluntary risk disclosure includes several aspects, including financial risks, including risks of interest rate, exchange rate, liquidity as well as risks of operations. In Jordan, the most common type of business is family businesses, where boards of directors usually serve the interests of the family that owns the majority stake in the company.This study identifies the moderate effect of family in the link joining the audit committee with the voluntary risk disclosure of financial institutions in Jordan. It's population is the Jordanian commercial banks registered and operating in Jordan during the period extending from 2017 to 2023.Significantly, it concluded with revealing that the characteristics of the audit committee; namely, independence, experience, and committee size, obviously impact disclosure of voluntary risk in the selected banks. However, the results made it obvious that the number of audit committee meetings did not affect the degree of voluntary risk disclosure. In addition, the results view family ownership as moderately affecting the relationship joining some audit committee characteristics with voluntary risk disclosure.

Betrayed, Beaten, Banished: The Stigma of Being a Rural Tongqi in China
Authors: Tsang Eileen , Fang Yueyao
Published: August 2024

Tongqi - women married to men who have sex with men (MSM) – from rural China encountered multi stigma with their male partners, family, community, local bureaucracies, and national laws, such as the hukou system, form a complex tapestry of life. The analysis navigates through various dimensions of stigma, reflecting systematically on their mutual implications. Social structures, including class and gender, shape societal norms and behaviors. This study explores the under-researched influence of social interaction, community relationships, and macrostructural factors contributing to the enacted stigma experienced by Tongqi Data collected from 59 rural Tongqi, 11 of whom contracted human immunodeficiency virus (HIV) or acquired immunodeficiency syndrome (AIDs), reveals the significant role of extended kinship networks and macrostructural elements, such as hukou (household registration) and government officers, in shaping the stigma faced by Tongqi. The importance of village-level lineage structures and dynamics highlights how these lineage relationships, interwoven with gender practices, contribute to the enacted stigma, physical and psychological health, and well-being of Tongqi. These include mental health, post-traumatic stress, depression, functional impairment, and permanent disability. Others include reproductive health, unwanted pregnancies, sexually transmitted infections (STIs), and pregnancy complications.
Self-Tumor Antigens in Solid Tumors Turned into Vaccines by α-gal Micelles Immunotherapy
Authors: Galili Uri
Published: August 2024

A major reason for failure of the immune system to detect tumor antigens (TA) is the insufficient uptake, processing, and presentation of TA by antigen-presenting-cells (APC). Immunogenicity of public and private TA of the individual patient can be markedly increased by in situ targeting of tumor cells for uptake by APC, without the need to identify and characterize the TA. This is feasible by intra-tumoral administration of alpha-gal micelles comprised of glycolipids presenting the carbohydrate-antigen “alpha-gal epitope” (Galalpha1-3Gal beta1-4GlcNAc-R). Humans produce a natural antibody called “anti-Gal” (constituting ~1% of immunoglobulins) which binds alpha-gal epitopes. Tumor injected alpha-gal micelles spontaneously insert into tumor cell membranes, so that multiple alpha-gal epitopes present on tumor cells. Anti-Gal binding to these epitopes activates the complement system, resulting in killing of tumor cells, and recruitment of multiple APC (dendritic cells and macrophages) into treated tumors by chemotactic complement cleavage peptides C5a and C3a. In this process of converting the treated tumor into personalized TA vaccine, recruited APC internalize anti-Gal opsonized tumor cells and cell membranes, process the internalized TA and transport them to regional lymph-nodes. TA peptides presented on APC activate TA specific T and B cells to proliferate and destroy metastatic tumor cells presenting the TA. Studies in anti-Gal producing mice demonstrated induction of effective protection against distant metastases of the highly tumorigenic B16 melanoma following injection of natural and synthetic alpha-gal micelles into primary tumors. This treatment was further found to synergize with anti-PD1 antibody. Phase-1 clinical-trials indicated that this immunotherapy is safe and can induce infiltration of CD4+ and CD8+ T cells into untreated distant metastases. It is suggested that in addition to converting treated metastases into autologous TA vaccine, this treatment should be considered as neo-adjuvant therapy administering alpha-gal micelles into primary tumors immediately following their detection. Such immunotherapy will convert tumors into personalized anti-TA vaccine for the period prior to their resection.
The Collatz Conjecture "The Nonexistence of Divergent Orbits, through a Dynamic Diophantine Linear Analysis of Codification
Authors: Fuentes Giovanny
Published: August 2024

We define the function $Col: \mathbb{N} \to \mathbb{N}$ as the Collatz function, given by $3n + 1$ if $n$ is odd and $\displaystyle\frac{n}{2}$ if $n$ is even \cite{Lagarias1990}. The conjecture postulates that for any positive integer, at some point, its iteration will reach 1, or equivalently, every orbit will fall into the periodic cycle $\{4, 2, 1\}$. Two conditions would invalidate the conjecture: the existence of a divergent orbit or the presence of another cycle. In 2019 Terence Tao \cite{tao} proved that almost all orbits converge to the trivial cycle of $\{1,4,2\}$, in this work we will prove the non-existence of divergent orbits. The central idea is to decompose the dynamic system $Col$ into a binary dynamic system, generated by different compositions of two functions. This differs from a typical dynamic system, which is generated by the iteration of a single function. We consider the system generated by the functions $\theta, \psi: \mathbb{R} \to \mathbb{R}$, defined as $\displaystyle\theta(x) = \frac{x}{2}$ and $\displaystyle\psi(x) = \frac{3x + 1}{2}$, denoted as $\langle \theta, \psi \rangle$. We examine sequences of functions in $\langle \theta, \psi \rangle$ of the form $S_k(x) = s_k \circ S_{k-1}(x)$ with $s_k \in \{\theta, \psi\}$. We define a function that assigns to each element of these sequences an integer, called the minimum value positive integer or simply the minimum value. This corresponds to the smallest positive integer $n$ such that $S_k(n)$ is an integer. As we will prove later, the minimum value is monotonically increasing, meaning that increasing the terms of the sequence will never result in a value lower than the previous one. Based on this behavior, we distinguish two types of sequences: stable ones, where the minimum value is constant from a certain point, and unstable ones, where the minimum value is divergent. The main result for unstable sequences is that when the slope of the sequence is divergent, the sequence is unstable. From this result, we can prove that there are no divergent orbits for the function $Col$.

Research on the Application of RAP Fine Aggregate Based on HMAC Design Concept
Authors: Xiao Kou
Published: August 2024

In order to apply RAP fine aggregate to High Modulus Asphalt Concrete(HMAC), this study first extracts aged asphalt from RAP fine aggregate through extraction and distillation, and adds it to high modulus modified asphalt in proportions of 20%, 40%, 60%, and 80%. The performance changes of the recycled asphalt were investigated using conventional performance tests and dynamic shear rheological tests (DSR). Microscopic techniques such as four‐component analysis and infrared spectroscopy were employed to explain macroscopic performance changes in terms of component and functional group changes in the asphalt. Using HMAC‐20 gradation as an example, uniaxial compression dynamic modulus tests, rutting tests, freeze‐thaw splitting tests, and low‐temperature bending tests were conducted to evaluate the performance changes of recycled asphalt mixture with different RAP fine aggregate contents through four indices: dynamic modulus, dynamic stability, tensile strength ratio (TSR), and maximum bending strain. The results indicate that for every 20% increase in aged asphalt, the penetration at 25°C, ductility at 25°C, and dynamic viscosity at 60°C decrease by approximately 6.2%, 15.4%, and 3.9%, respectively, while the softening point increases by approximately 13.3%. It is concluded that the addition of aged asphalt significantly affects the ductility at 25°C and the softening point. As the aged content increases, the complex shear modulus (G*) and phase angle (δ) of the recycled asphalt decrease, while the rutting factor increases. The four‐component analysis and infrared spectroscopy of the asphalt demonstrate that the incorporation of aged asphalt is merely a physical blending phenomenon, involving changes in the content of the four components without the formation of new functional groups (new peaks). When RAP fine aggregate is applied to high modulus recycled asphalt mixture, compared to high modulus modified asphalt mixture, the recycled mixtures exhibit higher dynamic modulus and dynamic stability, but significantly reduced water stability and low‐temperature performance.

Post-infectious cough during epidemics of acute respiratory infections is observed in 50% of children. The diagnosis of postinfectious cough is considered as clinical diagnosis. The expediency of treating post-infectious cough is debated. It is indicated that the effectiveness of all described methods of treatment of post-infectious cough has not been proven. Objective. Assessment of the expediency of pos-tinfectious cough therapy and the possibility of optimizing. Patients and methods. An observational study of the effectiveness of treatment of post-infectious cough was conducted. The observed patients were divided into the main (n = 940) and the comparison group (n = 936). Patients in the comparison group were treated with butamirate citrate in age-related doses for 14 days. The patients of the main group were treated with the herbal medicine Bronchipret® (Bionorica CE, Germany) at an age dose for 2 weeks. The effectiveness of treatment was assessed by the dynamics of clinical symptoms: complaints of coughing during the day and at night, auscultation of the lungs. Results. In the observed patients of both groups, day and night cough, cough during the day was observed equally often, in 2 weeks after the treatment, cough persisted in 12.8% of patients in the main group, and in 54.9% of patients in the comparison group. (p = 0,0000). Day and night cough after 2 weeks in the compared groups were equally common in 3.6% and 3.1% of patients in the main group, and in 7.9% and 7.2% of children in the comparison group (p = 0.0001; 0.0000).In 3 months after the start of follow-up, cough persisted in 1.8% of patients in the main group, and in 26.3% of children in the comparison group (p = 0.0000). Conclusion. Therapy of post-infectious cough is advisable. A possible option for optimizing the treatment of post–infectious cough in children and adolescents is two week therapy with Bronchipret® at an age-appropriate dose, which can be recommended in all cases.

Inflammatory bowel disease (IBD) is a group of chronic idiopathic recurrent inflammatory diseases of the gastrointestinal tract. The association between the increasing incidence of IBD worldwide and increased consumption of the Western diet suggests that host nutrition may influence the progression or treatment of IBD through the microbiome. The role of diet therapy in the treatment of patients with IBD is widely studied today. Although the mechanisms of their action have only been partially studied, existing studies suggest that diet-induced changes in microbial composition and functions underlie a variety of dietary therapy mechanisms. Despite existing treatments for IBD nutrition is an important treatment option due to its excellent safety profile, potentially low cost, and benefits for growth and development. In this review, we describe the clinical efficacy of various enteral nutrition options in inducing and maintaining remission of IBD. Exclusive enteral nutrition is currently the first-line therapy in the induction of Crohn’s disease (CD) remission in pediatric patients. The use of partial enteral nutrition and Crohn’s Disease Exclusion Diet has not proven effective in inducing remission of CD, but based on improved tolerance profiles, it shows good results in maintaining remission. Most researchers and the opinions of the conciliation documents conclude that a more in-depth study of the effectiveness of partial enteral nutrition and Crohn’s Disease Exclusion Diet in patients with CD is necessary.

Abstract
This research is intended to synthesize UPR/core-shell composites based on rice husk as a microwave absorber. In this study the materials used are silica, and magnetite. Silica material is produced from rice husk using sol-gel method, while Fe3O4 is produced from electrolysis process. These two materials are then combined into one forming a shell-core where the magnetite (Fe3O4) is the core (core part) and the silica (SiO2) as the shell (the outer). The composite was then made with Fe3O4-SiO2 composite core as the filler and as a UPR matrix with certain composition. Composites are made with some compositions then do the microwave absorption try using VNA (Vector Network Analyzer) at the frequency of 8 GHz - 12 GHz. VNA test results show that UPR/core-shell material is able to absorb the best microwave, with the composition of 80%: 20% and absorption at 11 GHz frequency with absorption of -19. 009 dB.

Objectives. To assess differences in contextual factors by intent among pediatric firearm injury patients and determine factors associated with data missingness.

Methods. We retrospectively queried the American College of Surgeons Firearm Study database (March 1, 2021–February 28, 2022) for patients aged 18 years or younger. We stratified preinjury, firearm-related, and event-related factors by intent and compared them by using Fisher exact, χ2, or 1-way analysis of variance testing. Secondary analysis estimated the adjusted odds of missingness by using generalized linear modeling with binominal logit link.

Results. Among 17 395 patients, 2974 (17.1%) were aged 18 years or younger; 1966 (66.1%) were injured by assault, 579 (19.5%) unintentionally, and 76 (2.6%) by self-inflicted means. Most contextual factors differed by intent, including proportion of youths with previous adverse childhood experiences, mental illness, and violent assaults or injury, firearm type and access, perpetrator relationship, and injury location. In adjusted analyses, age, trauma center designation, intent, and admission status were associated with missingness.

Conclusions. Contextual factors related to pediatric firearm injury vary by intent. Specific predictors associated with missingness may inform improved future data collection.

Public Health Implications. Contextual factors related to pediatric firearm injury can be obtained in a systematic manner nationally to inform targeted interventions. ( Am J Public Health. 2024;114(10):1097–1109. https://doi.org/10.2105/AJPH.2024.307754 )

Published: August 2024

Case:

(1) A 69-year-old man sustained a proximal humeral fracture-dislocation. During emergency surgery, copious bleeding occurred. A pseudoaneurysm was identified 30 days postoperatively. (2) A 69-year-old man sustained a proximal humeral fracture and axillary artery injury. Physical examination demonstrated a cold but pink hand. Hemiarthroplasty and bypass vein grafting were performed. (3) An 86-year-old woman sustained a proximal humeral fracture and axillary artery injury. Her hand had turned cold and pale. Reverse shoulder arthroplasty and bypass vein grafting were performed.

Conclusion:

In cases of proximal humeral fractures with significant displacement, concomitant axillary artery injury must be assessed and if there is a high index of suspicion, prompt advanced imaging is necessary.
Applicability of fatigue design recommendations for thin plate welded joints by assessment of fatigue crack initiation and propagation life
Authors: Kanna Sohei , Takanashi Masahiro
Published: August 2024

Fatigue design guidelines for welded joints are primarily based on tests of around 10mm thick joints. Fatigue strength generally decreases with increased thickness, likely due to increased stress concentration or changes in stress distribution. Thus, guidelines correct and reduce the fatigue strength of thicker joints. However, for thinner plates commonly used in railway cars, there is limited test data and it is unclear if the guidelines apply. This study conducted a 4-point bending fatigue test on a 3mm thick fillet welded joint to determine fatigue strength. Contrary to expectations, fatigue strength decreased when thickness reduced from 9mm to 3mm. However, test results showed higher fatigue strength than the recommended value, confirming that the guidelines can apply to 3mm thickness. Additionally, the study investigated the reduced fatigue strength of thin plates using the relationship between the number of cycles to crack initiation, local stress range, and crack growth analysis based on Paris' law. It found that as thickness decreases, the stress concentration at the weld toe decreases and the number of cycles to crack initiation increases. However, the ligament also shrinks, resulting in a shorter crack propagation life.
A Lumped Parameter Modelling Study of Idiopathic Intracranial Hypertension: Does the CSF Formation Rate vary with the Capillary Transmural Pressure?
Authors: Bateman Grant Alexander , Bateman Alexander Robert
Published: August 2024

Studies simultaneously measuring the intracranial pressure (ICP) and sagittal sinus pressures in idiopathic intracranial hypertension (IIH), suggest either a reduction in the CSF outflow resistance or the CSF formation rate. A study maintaining the ICP at zero showed a significantly elevated CSF formation rate. The purpose of this study is to define the most feasible explanation for these findings. A lumped parameter model originally developed to study normal pressure hydrocephalus was extended to investigate IIH. The model was used to estimate the CSF formation rate and the capillary transmural pressure (TMP), utilizing the data from 4 experiments published within the literature. When the CSF formation rates of these 4 studies were plotted against the estimated capillary transmural pressures, a straight line with an R2 of 0.999 was returned. The model suggests the CSF formation rate in IIH varies with the capillary TMP. A reduced capillary TMP secondary to a reduced blood flow in IIH moderates the ICP. The variation in formation rate is most likely a function of the blood brain barrier (BBB) breakdown known to occur in this disease. Drugs which stabilize the BBB may trigger IIH.
