Published: August 2024

Students' abilities in mathematics are very necessary in learning mathematics. One way to determine the level of students' ability to solve mathematical problems is with the SOLO taxonomy. This taxonomy consists of five levels: Prestructural, Unistructural, Multistructural, Relational, and Extended Abstract. This research is descriptive qualitative research. The research subjects were taken from 3 students in class X-4 of SMA Negeri 1 Jombang, and the criteria were that students had high, medium, and low mathematics abilities. The data collection methods used were tests, interviews, documentation, and supporting instruments in the form of problem-solving tests, interview guides, and documentation. Time triangulation was carried out to check the validity of the research data. The results of research on mathematical problem-solving abilities based on the SOLO taxonomy for subjects with high mathematical abilities and subjects with moderate mathematical abilities show that the subjects are at the Extended Abstract level, which means that the subjects can prove the truth regarding the results obtained so that the results obtained are relevant so that the subjects can make hypotheses in the form of formulas, patterns, or rules for solving problems. Students can generalize or apply mathematical concepts involved in the problem to similar situations or problems. Subjects with low mathematical ability indicate that the subject is at the Multistructural level, which means the subject can describe the steps in solving the problem, but there are still calculation errors.

The importance of education and role of educational institutions in climate change mitigation and achieving UN SDG 13 Climate Action
Authors: Priatna Dolly , Khan Shujaul Mulk
Published: August 2024

Climate change is a long-term shift in weather patterns driven by natural and human activities, leading to global warming and extreme weather events. Education - both formal and informal, plays a crucial role in climate change mitigation by enhancing awareness, fostering critical thinking, and promoting sustainable practices. It equips individuals with the knowledge and skills necessary to understand the complexities of climate change and engage them in informed decision-making. Education also promotes innovation and solutions, supports policy and advocacy, builds resilience, and empowers vulnerable populations. Climate change mitigation strategies align with Sustainable Development Goal 13 (SDG 13) “Climate Action”, but they also present synergies and trade-offs with other SDGs. Large-scale implementation of technologies can positively impact economic growth and job creation, but environmental issues linked to mineral extraction can detract from other SDGs. Careful management is essential to balance these interactions and minimize trade-offs. Educational institutions play a crucial role in achieving Sustainable Development Goal 13 (SDG 13) by fostering knowledge, research, advocacy, and sustainable practices. They contribute to climate education and awareness through curriculum development, research and innovation, leadership and institutional action, policy advocacy, capacity building, community engagement, ethical and sustainable values education, and monitoring and reporting. Higher education institutions can integrate climate change education into curricula, equipping students with the necessary skills to address environmental challenges. They can also promote global citizenship and empower individuals to contribute to climate solutions. By incorporating multidisciplinary approaches, educational institutions can bridge gaps in climate education and promote innovative solutions to mitigate climate impacts.

Studi Komparasi Ahli Waris Pengganti (Plaatsvervulling) Dalam Perspektif KUH Perdata dan Kompilasi Hukum Islam
Authors: Muhammad  , Ahmad Syahrial , Ramdhan Abdul Wahid Bagoes Timor Ali
Published: August 2024

According to Pasal 185 of the Compilation of Islamic Law, a feeling of justice serves as the basis for institutionalizing alternative inheritance. In contrast, KUH Perdata includes clauses addressing replacement and replacement heirs (plaatsverfuling). Due to the continued application of customary law, Islamic law, and western law, inheritance law in Indonesia is still generally pluralistic. However, KUH Perdata and KHI are those pertaining to substitute heirs. Therefore, the authors are motivated to compare alternative heirs from the viewpoints of KUH Perdata and KHI. The author's preparation for the piece includes qualitative research with descriptive analytic techniques. The three stages of the data analysis process—description, formulation, and interpretation—are used in comparison analysis. According to the study's findings, if one heir dies before another heir, the child of the heir is then entitled to take the place of his father, in accordance with KHI and KUH Perdata of inheritance law. There are differences in the amount of the accepted heir's share; for example, KUH Perdata receives an equal share to the replacement, unlike KHI, which is not always the same as the replacement and does not exceed the share of equal heirs, and may even be reduced based on the replacement heir's sex. Additionally, KUH Perdata differs in that they enter information to determine the heirs.

Authors: Bani Maulidan Al , Islam Ahmad Fakhruddin Fajrul
Published: August 2024

In this study, there are two problem formulations, namely: (1) What is the communication pattern of fostering students with ODGJ through Islamic values in Padepokan Tahfidhul Qur'an Ibn Rusydi? (2) What are the aspects that support and hinder the communication process in fostering ODGJ students in Padepokan Tahfidhul Qur'an Ibn Rusydi? To answer the two formulations of the problem. The researcher adopts a qualitative approach with a descriptive type in this study. The results of this study can be concluded that the communication pattern of ODGJ students at Padepokan Tahfidhul Qur'an Ibn Rusydi between caregivers, administrators, and ODGJ students uses verbal and nonverbal interactions to teach and provide an understanding of Islamic values to ODGJ students. That way, ODGJ students will be encouraged to think critically and adapt well in the social environment. Supporting factors such as an open attitude and active interaction accelerate the coaching process. Meanwhile, the inhibiting factors such as ODGJ students who have difficulty communicating can hinder the understanding and application of Islamic values. Effective social interaction is the key to achieving the vision and mission of making students noble individuals.

Perforation of the skin by fragment impact is a key determinant of the severity of an injury and incapacitation during modern asymmetric warfare. Computational models validated against experimental data are thus desired for simulating the responses of a skin simulant against fragment impact. Toward this end, experiments and concurrent computational modeling were used to investigate the dynamic responses of the skin simulant against fragment impact. Fragment simulating projectiles (FSPs) of masses 1.10 g and 2.79 g were considered herein, and the responses of the skin simulant were investigated in terms of the threshold velocity, energy density, peak displacement, and failure mechanisms. The results illustrate numerous salient aspects. The skin simulant failure involved cavity shearing followed by elastic hole enlargement, and these results were sensitive to the strain rate. The best agreement between the simulated and experimental results was achieved when the input stress–strain curves to the simulation were based on the full spectrum of strain rates. When a single stress–strain curve corresponding to a specific strain rate was used as the input, the threshold velocity and peak displacement of the skin simulant were either underpredicted or overpredicted depending on the strain rate considered. The threshold velocity was also sensitive to the input failure strain; here, the best agreement was obtained when the failure strain was based on the theoretical limiting strain. When the FSP materials were changed to plastics, the threshold velocities increased by up to 33%; however, the energy densities and generated stresses exceeded the contusion and laceration thresholds of the skin.

Objective

The purpose of this study was to determine the effects of hammer rotation on performance in hammer throwing.

Methods

The hammer’s velocity increment at different stages, the duration of rotations at different phases, and the horizontal azimuth angle and rotation radius at critical instants were calculated and compared between the long and short trials for 26 female athletes in actual competitions.

Results

Compared to short trials, female throwers’ long trials exhibited significantly larger release velocity (p < 0.001, ES = 1.42), greater velocity increment during the double support phase (p = 0.006, ES = 0.59), shorter duration during the single support phase (p ≤ 0.043, ES = 0.42–0.83), lower horizontal azimuth angle (p ≤ 0.027, ES = 0.46–0.57), and longer rotational radius at critical instants (p ≤ 0.021, ES = 0.48–0.73).

Conclusion

During the process from the hammer head’s low point to high point, athletes should focus on increasing the rotation radius of the hammer head and accelerating the right foot’s landing speed during the single support phase. This approach aims to reduce the hammer’s horizontal azimuth angle at the right foot touchdown, enhance the acceleration performance during the double support phase, and increase the release speed.

The development of concrete with excellent water and frost resistance providing high level of sound and thermal insulation has triggered the formulation of foamed concrete. However, multiple laboratory studies are required to produce reasonable data to design the relevant codes and mathematics with which design of mixes is made easier at low cost. In this research paper, the artificial intelligence (AI)-based symbolic regression technique estimation of the compressive strength of foamed concrete has been reported. Foamed concrete has been a subject of serious research in sustainable built-environment due to its lightweight and structural functionality. In this research work, data gathering method was applied to gather a globally representative data base comprising concrete density to water density (concrete density g/cm3) (γ/γw), water-cement ratio (W/C), and sand-cement ratio (S/C) as input variable and the compressive strength (Fc) as the study output. The dimensionless factors have been derived to eliminate data handling complexities and improve model performances. The 230 data entries from foamed concrete mixes were partitioned into 75% and 25% for training and validation data, respectively. At the end of the model execution, it was found that the response surface methodology (RSM) produced a symbolic closed-form equation like the genetic programming (GP), evolutionary polynomial regression (EPR), and the group method of data-handling-neural network (GMDH-NN). Even though the RSM closed with a minimum error, the GP, EPR and GMDH-NN were faster in runtime. The overall outcomes show that the GP outclassed the EPR, RSM and the GMDH-NN, though with minor margin. Meanwhile the EPR produced the highest outliers from the ±25% test of accuracy envelope. Overall, the present models outperformed those reported in the literature due the parameter reduction through dimensionless factors derivation and provided a decisive model to predict the Fc of foamed concrete.
Glial modulation of synapse development and plasticity: oligodendrocyte precursor cells as a new player in the synaptic quintet
Authors: Akinlaja Yetunde O. , Nishiyama Akiko
Published: August 2024

Synaptic communication is an important process in the central nervous system that allows for the rapid and spatially specified transfer of signals. Neurons receive various synaptic inputs and generate action potentials required for information transfer, and these inputs can be excitatory or inhibitory, which collectively determines the output. Non-neuronal cells (glial cells) have been identified as crucial participants in influencing neuronal activity and synaptic transmission, with astrocytes forming tripartite synapses and microglia pruning synapses. While it has been known that oligodendrocyte precursor cells (OPCs) receive neuronal inputs, whether they also influence neuronal activity and synaptic transmission has remained unknown for two decades. Recent findings indicate that OPCs, too, modulate neuronal synapses. In this review, we discuss the roles of different glial cell types at synapses, including the recently discovered involvement of OPCs in synaptic transmission and synapse refinement, and discuss overlapping roles played by multiple glial cell types.
Case Report: Unmasking sustainable left ventricular recovery in chronic heart failure with axillary temporary mechanical circulatory support
Authors: Desai Aarti , Sharma Shriya , Luce Caitlyn , Ruiz Jose , Goswami Rohan
Published: August 2024

Background

Mechanical circulatory support (MCS), temporary or durable, is essential in patients with acute heart failure presenting in cardiogenic shock (CS). MCS is fundamental in patients with advanced heart failure when used as a bridge to decision, transplant or left ventricular recovery. Limited data on acute-on-chronic heart failure (HF) patients exists in the era of axillary mechanical circulatory support with the Impella 5.5. We describe a case of chronic ischemic cardiomyopathy, HF-CS, in a patient who underwent Impella placement, medical optimization, and explant, now with sustained normalization in ejection fraction.

Case summary

A Caucasian female in her 50 s was referred to our center for evaluation for advanced therapies, including transplantation or durable left ventricular assist device placement. Her initial ejection fraction was 30% with comorbidities including multivessel coronary artery disease revascularized with 3 vessel bypass grafting ten years prior, type 2 diabetes (A1c 8.6%), and peripheral vascular disease. During her evaluation, she had acute decompensation leading to cardiogenic shock and required hospitalization with inotrope initiation, which was unable to be weaned. She was approved for organ transplant and listed; however, she required escalation of support and eventual placement of right axillary Impella 5.5. While on Impella support, her vasoactive needs reduced, and she was found to have left ventricular recovery and tolerated the initiation of guideline medical therapy. After three weeks of support, the Impella was weaned and explanted, and the patient was discharged. She remains stable with a sustained ejection fraction of greater than 50% with NYHA class 1 functional status at follow-up. One year later, the patient showed sustained myocardial recovery with guideline-directed medical therapy (GDMT).

Conclusion

Our case highlights a unique approach in patients with long-standing (>5 years) heart failure who may benefit from early consideration for axillary support and concomitant optimization with guideline-directed medical therapy to assess for explant and native heart recovery.

Published: August 2024

Studies have shown that primary cardiac tumors are exceptionally rare and among them myxomas represents approximately half. Although majority of these benign tumors are located in left atrium, they can also emerge in the right cardiac chambers and also on cardiac valves. In rare instances, they may extend into the great vessels. In this case, we present a teenage girl with a past medical history of successfully cured acute lymphoblastic leukemia, who presented with progressive dyspnea and lower limbs edema. Based on history, laboratory, and echocardiographic evidences, she was initially treated for high-risk thromboembolism but after inefficient response, she underwent surgery, with a large right ventricular outflow tract myxoma being diagnosed.

Subsidence refers to the gradual lowering or sudden sinking of the ground surface and is known to impact human lives in terms of damages to the infrastructures, utility lines, and buildings as well as changes in the surficial drainage systems and groundwater conditions. The impacts of land subsidence will be greater in the future, considering the sea level rise, population growth, intensification of coastal erosion and extreme events, as well as increase in flood risk or freshwater salinization, mostly in coastal cities. The main aim of this work is to provide an open-source, peer-reviewed, and comprehensive database identifying the main and secondary causes of land subsidence in 143 coastal cities. We highlight the potential impacts of subsidence that are still unknown in some at-risk cities and non-existence of mitigation measures. The database additionally shows that mitigation measures, specifically those addressing subsidence due to groundwater extraction, have proven successful in the past. The proposed database aims to increase the knowledge on the subsidence phenomenon and also global awareness of land subsidence issues among researchers, the scientific community, stakeholders, and policymakers in terms of urban planning and development.
