Comparative analysis of Generation Z's digital history literacy in history education majors on Java Island: A study of history digital literacy
Authors: Kumalasari Dyah , Purwanta Hieronymus , Suranto
Published: January 2024

The purpose of this study is to determine the level of digital literacy related to history among students at Universitas Pendidikan Indonesia (UPI) and the State University of Malang (UM). The recent decline in historical literacy among Indonesians has piqued historians' interest.  In this context, the gap between technological potential and literacy problems may be advantageous for initiatives to enhance Indonesian young historical literacy. This research uses a quantitative-descriptive approach. The respondents were first-year and second-year history students at UPI and UM. The data collection technique used was a historical literacy test that has Higher Order Thinking Skills (HOTS) levels 1-4. This study used descriptive data analysis and an independent sample t-test. The results of this study show that students from both universities have a low level of historical literacy, both in first-year and second-year students. This condition is a signal for teachers to start improving. Gadget technology is suggested as a solution to the problem because these students belong to Generation Z (a generation that is very aware of current events and technological advancements). The methodology of Scholarship of Teaching and Learning (SOTL) was selected because its principles are appropriate for fostering digital historical literacy. It is student-focused, context-based, collaborative, methodical and well-developed in the community.
Assessment of the impact of sampler housing on indoor passive air sampler measurements of SVOCs
Authors: Vojta Šimon , Melymuk Lisa , Prokeš Roman , Klánová Jana
Published: January 2024

Passive air sampling (PAS) using a polyurethane foam (PUF) sorbent is a widely used technique to characterize air concentrations of semi-volatile organic compounds (SVOCs) in indoor environments; however, there is little consensus on the type of housing used in sampler housings and how sampler masses are converted to air concentration. We systematically evaluate the three types of PUF-PAS sampler housings most commonly used indoors, and characterize uptake rates for > 50 SVOCs, covering legacy persistent organic pollutants, pesticides, combustion by-products, and flame retardants for all three housing types. There is a clear association between the amount of shielding of the PUF disk and equivalent air volumes for PUF-PAS, with median sampling rates for double-bowl housings of 0.72 m3/day (0.62-0.92 m3/day), 1.3 m3/day (1.0-1.7 m3/day) for single bowl, and 1.8 m3/day (1.4-2.2 m3/day) for PUFs without any housing. Combining these outcomes with a meta-analysis of existing data on PUF-PAS indoor uptake, we provide recommendations for the range of applicability and selection of sampling rates for PUF-PAS in indoor environments.
How Much Cosmic Time Does It Take for a Star to Collapse Forming a Black Hole?
Authors: Haro Jaume
Published: January 2024

The concept of a black hole is examined through a historical lens, emphasizing the distinctions between its mathematical definition and the observed phenomena in the cosmos. An essential point of contention is highlighted, the challenge of reconciling the ultimate state of gravitational collapse, conceptualized as a black hole with its associated future event horizon, with the vast age of the universe as measured in cosmic time. The work delves into the evolution of black hole theories, tracing their development from the early mathematical solutions, such as the Schwarzschild solution, to the contemporary understanding shaped by contributions from Hawking and Penrose. The complex interplay between mathematical descriptions and observational realities is explored, shedding light on the difficulties inherent in merging theoretical concepts with astrophysical observations. A particular focus is placed on the discrepancy between the theoretical formation of a black hole and the seemingly infinite cosmic time required for the collapse process according to the seminal work of Oppenheimer and Snyder. This apparent incongruity raises questions about the nature of objects labeled as black holes in astrophysics and prompts a critical examination of how observational data align with theoretical predictions. In essence, this exploration underscores the need for a nuanced and critical analysis of the concept of black holes, considering the intricate interplay between theoretical constructs and empirical observations within the framework of General Relativity.
Mengatasi Overdispersi Menggunakan Regresi Binomial Negatif dengan Penaksir Maksimum Likelihood pada Kasus Demam Berdarah di Kota Makassar
Authors: Fadil Muhammad , Raupong Raupong , Ilyas Nirwan
Published: January 2024

The basic assumption in Poisson regression is that the mean value is the same as the variance value, which is called equidispersion. However, in some cases, this assumption is not met. A variance value that is greater than the average is called overdispersion and is called underdispersion if the variance value is smaller than the average value. So the Poisson regression model is no longer suitable for modeling this type of data because it will produce biased parameter estimates, therefore a negative binomial regression model is used. The research results show that estimating the parameters of the negative binomial regression model uses the maximum likelihood estimation method and then continues with the Newton-Raphson iteration method. The results obtained show that the negative binomial regression model overcomes the overdispersion that occurs in data on the number of dengue fever cases in Makassar City with the model  and an AIC value of 236.06647. The negative binomial regression model produces many models and then the best model with the smallest AIC criteria is selected.

The efficacy of nationwide population control initiatives in Indonesia ought to be uniformly dispersed throughout all provinces. The decentralization policies implemented by each local government and regional differences in characteristics have, nevertheless, resulted in substantial discrepancies in TFR across all provinces in Indonesia. The efficacy of long-acting contraceptives is widely acknowledged as the primary prerequisite for mitigating the pace of population growth. In addition to reducing the TFR, the government has established goals for the equitable distribution of family planning programs across Indonesia. The implementation of family planning programs in an equitable manner will impact the birth rate reduction. The objective of this research is to examine the potential impact of contextual elements on fertility reduction via contraceptive methods in Indonesia. The findings of this research indicate that the proportion of women utilizing long-acting contraceptive methods has the most significant impact on TFR reduction in Indonesia, at -0.562. In contrast, the HDI and the number of family planning villages each have an influence of -0.12 and -0.36, respectively, on TFR reduction.

Authors: Orellana Samanta , Girón Duque Jennifer C.
Published: January 2024

Anthribidae is a small family of beetles known as fungus weevils, for which the state of knowledge for Colombian species has never been synthesized. Anthribids are scarce in Colombian biological collections and are usually only identified at the family level. We updated the list of species of fungus weevils recorded from Colombia. There are 37 species of anthribids recorded for the country, placed into 14 genera, 10 tribes, and 2 subfamilies. Three additional genera have been observed in the country based on records from the online platform iNaturalist. Verification of these records and species-level identifications require the revision of national biological collections. We discuss the biodiversity of Colombian fungus weevils compared to neighboring countries and provide a key to identify the genera present in Colombia. The species Domoptolis championi Jordan, 1906 is recorded for Colombia for the first time.

La utilización de harina de grillo en la alimentación humana es un tema que ha ganado tracción en los últimos años debido a sus beneficios nutricionales y ambientales. La cría de grillos es una práctica sostenible que requiere menos recursos naturales en comparación con la producción de carne tradicional. Los grillos requieren menos agua, espacio y alimentos, y generan menos emisiones de gases de efecto invernadero. La harina de grillo es rica en proteínas, fibra, vitaminas y minerales. Contiene todos los aminoácidos esenciales, lo que la convierte en una fuente de proteína completa, reemplazando y modernizando la forma de alimentación humana, lo cual es muy interesante para la industria alimentaria y el medio ambiente. En muchos países, la harina de grillo ha sido aprobada para consumo humano. Sin embargo, es fundamental que los grillos sean criados, procesados y preparados adecuadamente para garantizar su seguridad alimentaria. La incorporación de la harina de grillo en productos alimenticios convencionales, como panes, barras de proteínas y snacks, puede facilitar su aceptación.

Published: January 2024

Los reguladores de crecimiento para plantas han sido evaluados en varias especies de algas rojas para estimular su desarrollo, dando respuestas positivas. Así mismo, se encuentran escasos protocolos en el uso de estas fitohormonas en la regeneración celular adaptados al cultivo de Chondracanthus chamissoi, como mecanismo de optimización de los procesos de fijación y crecimiento inicial de plántulas de esta especie, es por ello que se buscó experimentar con reguladores de crecimiento para plantas comerciales. En tal sentido, se llevó a cabo una evaluación del desarrollo y crecimiento de los talos de C. chamissoi en condiciones controladas de laboratorio bajo el efecto de un bioestimulante hormonal comercial (TRIGGRR®) en este proceso. El experimento se diseñó con ocho tratamientos diferentes. Los tratamientos 1, 2 y 3 fueron expuestos a concentraciones de 0.5, 5 y 50 µl L-1 respectivamente y a su vez los tratamientos 4, 5 y 6 fueron expuestos a las mismas concentraciones, pero se les adicionó 0.2 ml L-1 de nutriente (Bayfolan®) a cada uno de ellos. Por último, se incluyeron dos controles: el tratamiento 7, que contenía 0.2 ml L-1 de Bayfolan®, y el tratamiento 8, al cual no se le añadió ningún compuesto. Los mejores resultados obtenidos para cada variable fueron 5.02 ± 0.45 % dia-1 para la tasa de crecimiento en talla, procedente del tratamiento 4; y los otros provinieron del tratamiento 5 siendo la tasa de crecimiento en peso 0.52 ± 0.16 % dia-1, la proporción de brotes 49.35 ± 4.86 brotes g-1 y la tasa de brotes 0.66 ± 0.06 brotes g-1 dia-1. No se encontraron diferencias significativas en ninguno de los tratamientos.

Authors:   , Quiroz Pinto Katerin Brillit
Published: January 2024

El fenol es considerado como uno de los compuestos orgánicos más tóxicos por su baja tendencia a biodegradarse, permaneciendo en el ambiente y conservando su carácter nocivo. Debido a su complejidad en la degradación, se utilizó un tratamiento con microburbujas de oxígeno (O2) generadas por electrólisis. El tratamiento fue evaluado con cinco concentraciones de fenol (1.0 M, 0.8 M, 0.4 M, 2.0 M y 3.0 M), cuatro valores de pH (2.0, 2.5, 3.0 y 3.5) en un volumen de 500 mL. Los electrodos de acero inoxidable (AI-304) y carbono fueron conectados a una fuente de energía de 12V y 40A. Se extrajeron dos muestras experimentales por cada tiempo de tratamiento de 1 a 30 min. El análisis cinético fue evaluado con tres concentraciones de fenol (1.0 M, 0.4 M y 2.0 M) en un intervalo de 1 a 20 min. La degradación del fenol fue cuantificada por análisis fotométrico método colorimétrico 4-aminoantipirina. Se realizó un análisis estadístico ANOVA de tres factores, permitiendo demostrar que el tamaño del efecto de la variable “concentración inicial del fenol” es mayor con un 76%, la degradación máxima fue de 70.8% (concentración inicial del fenol 3.0 mg/L, pH 2 y tiempo de 30 min). Concluyendo que el sistema de microburbujas de O2 generadas por electrólisis se presenta como un tratamiento eficiente en la degradación del fenol.

Published: January 2024

Los cambios en las futuras temperaturas generan un impacto en la productividad y calidad de las variedades de cultivos a nivel mundial. La quinua, es un importante cultivo por su tolerancia frente a la salinidad y sequía, y su respuesta al cambio climático. Por ello, este estudio tiene como objetivo comparar la respuesta de la transpiración a la sequía progresiva del suelo, y mecanismos fisiológicos asociados con esta respuesta en las variedades nativas de quinua peruana con importancia para la pequeña agricultura altoandina. Para ello, se utilizaron cuatro variedades comerciales INIA 420 Negra Collana, INIA 415 Pasankalla, INIA 433 Santa Ana e INIA 427 Amarillo Sacaca, el experimento se estableció a nivel de invernadero, contando con un testigo con riego normal y unos tratamientos de riego de estrés hídrico progresivo. El análisis de resultados demuestra que existe diferencia significativa en cuanto a la adaptación a la sequía; demostrando que cuando hay sequía en el suelo las cuatro variedades de quinua generan igual número de hojas; así como, difieren en su respuesta adaptativa de transpiración (NTR) ante la sequía progresiva del suelo reflejada en la fracción de agua transpirable que retiene el suelo (FTSW); en esta investigación se concluye que la variedad INIA 433 Santa Ana, presentó variación en la transpiración cuando hay déficit hídrico en el suelo entre sesenta por ciento y cincuenta por ciento, siendo la única variedad que potencialmente soportaría las nuevas condiciones de incremento de temperaturas en relación a la disponibilidad hídrica reducida en el suelo agrícola.

In-sensor and near-sensor computing architectures enable multiply-accumulate operations to be carried out directly at the point of sensing. In-sensor architectures offer dramatic power and speed improvements over traditional von Neumann architectures by eliminating multiple analog-to-digital conversions, data storage, and data movement operations. Current in-sensor processing approaches rely on tunable sensors or additional weighting elements to perform linear functions such as multiply-accumulate operations as the sensor acquires data. We implement in-sensor computing with an oscillatory retinal neuron device that converts incident optical signals into voltage oscillations. We introduce a computing scheme based on the frequency shift of coupled oscillators that enables parallel, frequency multiplexed, non-linear operations on the inputs. Simulation elucidates how this computing occurs. We experimentally implement a 3×3 focal plane array of coupled neurons and show that functions approximating edge detection, thresholding, and segmentation occur in parallel. An example of inference on handwritten digits from the MNIST database is also experimentally demonstrated with a 3×3 array of coupled neurons feeding into a single hidden layer neural network, approximating a liquid state machine. This network demonstrated a reduction in classification error from 2.16% to 1.84% compared to the same neural network with standard photodetector inputs. Finally, the equivalent energy consumption to carry out image processing operations, including peripherals such as the Fourier transform circuits, is projected to be < 20 fJ/OP, possibly reaching as low as 15 aJ/OP.

Background:
Endovascular techniques are advancing with the change of treatment paradigm for abdominal aortic aneurysms. Fenestrated EVAR (fEVAR) and branched EVAR (bEVAR) are used for complex aortic aneurysm repair. Both fEVAR and bEVAR have their own advantages and disadvantages. Semi-branches are a new feature that attempt to combine the advantages of both fEVAR and bEVAR.
Technique:
We describe the use of a 4-vessel semi-branched EVAR in a failed EVAR case with a type 1a endoleak.
Conclusion:
The novel feature of semi-branches in custom-made EVAR devices in endovascular aortic treatment following failed EVAR appear to be a feasible option.
Arrhythmogenic Right Ventricular Cardiomyopathy with Sustained Ventricular Tachycardia: A Case Report
Authors: Ban Ying , Yao Feng-juan , Li Wei
Published: January 2024

Introduction:
Arrhythmogenic right ventricular cardiomyopathy (ARVC) is a rare genetic disorder characterized by fibrofatty replacement of the right ventricular myocardium, which predisposes individuals to life-threatening arrhythmias. We present a case of an ARVC patient who experienced recurrent episodes of sustained ventricular tachycardia (VT). In this case, we mainly discuss the application of myocardial contrast echocardiography (MCE) in displaying myocardial fibrosis in ARVC.
Case presentation:
A 43-year-old male experienced three unexplained ventricular tachycardias within an eight-year period, accompanied by symptoms of chest discomfort, palpitations and dizziness. Coronary angiography revealed no significant coronary stenosis. The electrocardiogram (ECG) results indicated characteristic epsilon waves in right precordial leads, and subsequent echocardiography revealed right ventricular enlargement and right ventricular systolic dysfunction. MCE identified regional myocardial ischemia at the epicardium of left ventricular apex. Finally, cardiovascular magnetic resonance imaging (CMR) confirmed the presence of ARVC based on the linear intensification observed in the RV during the delayed enhancement.
Conclusion
To make sure timely intervention and management, early recognition is of paramount importance. MCE may offer an effective and valuable technique for the detection of myocardial involvement in ARVC patient.

The incidence of esophageal adenocarcinoma (EAC) has significantly increased, particularly in Western countries. Cathepsins are a group of lysosomal proteolytic enzymes; they are associated with the occurrence and progression of various tumors. However, the causal relationship between the cathepsin family and EAC remains unelucidated. To investigate this association, Mendelian randomization (MR) and bioinformatics analyses of single-cell RNA sequencing (scRNA-seq) data were performed. MR analyses revealed that high cathepsin B (CTSB) levels decreased EAC risk. Furthermore, scRNA-seq revealed that CTSB expression was primarily distributed in macrophages. In addition, MR analysis of CTSB and macrophage scavenger receptor types I and II verified their interrelationship; CTSB primarily affects the proinflammatory phenotype of macrophages. Our findings suggest that CTSB levels affect EAC progression by regulating the expression of macrophage scavenger receptor types I and II, which induce the proinflammatory phenotypes of macrophages. Therefore, targeting CTSB may provide avenues for EAC diagnosis and treatment.

Background To compare the clinical and radiological outcomes of modified mini-open transforaminal lumbar interbody fusion (mMO-TLIF) via posterior midline approach for "targeted limited dissection" versus minimal invasive transforaminal lumbar interbody fusion (MIS-TLIF) via Wiltse approach in lumbar degenerative diseases.Methods A total of 60 consecutive patients in our center from January 2019 to March 2020 were enrolled, including 30 patients who were treated with mMO-TLIF via posterior midline approach and 30 were treated with MIS-TLIF through the Wiltse approach. Perioperative parameters were recorded. The questionnaires of Oswestry Disability Index (ODI) and Visual Analogue Score (VAS) were conducted before the operation and after the operation (3 days, 1 week, and 2 years). CT and MRI radiological outcomes were evaluated before the operation and at a 2-year follow-up.Results All patients were successfully operated without intraoperative complications. The mMO-TLIF group was superior to MIS-TLIF group regarding the operation time and intraoperative bleeding. There was no difference in ODI and VAS scores between groups pre- and post-operatively, but they were both significantly improved compared to those before the operation (p < 0.01). At a 2-year follow-up, the paraspinal muscle atrophy and fat infiltration increased more than before the operation, but the difference was also not statistically significant (p > 0.05). In addition, both the two groups' fusion rates were more than 90% at a 2-year follow-up, however, no difference was detected between the two groups.Conclusion mMO-TLIF via midline approach for "targeted limited dissection" could achieve similar clinical and radiological outcomes as MIS-TLIF for lumbar degenerative disease.

Authors: He Chengwei
Published: January 2024

Introduction:
The efficacy of tralokinumab for atopic dermatitis remains controversial. We conduct a systematic review and meta-analysis to explore the efficacy of tralokinumab in patients with atopic dermatitis.
Methods
We search PubMed, EMbase, Web of science, EBSCO, and Cochrane library databases through September 2023 for randomized controlled trials (RCTs) assessing the efficacy of tralokinumab for atopic dermatitis. This meta-analysis is performed using the random-effect model.
Results
Three RCTs are included in the meta-analysis. In patients with atopic dermatitis, tralokinumab is associated with improved IGA score of 0/1 (RR = 1.77; 95% CI = 1.39 to 2.27; P < 0.00001) and EASI 50 (RR = 1.73; 95% CI = 1.31 to 2.29; P = 0.0001), reduced SCORAD score (SMD=-9.28; 95% CI=-11.58 to -6.99; P < 0.00001) and increased SCORAD 50 (RR = 2.28; 95% CI = 1.78 to 2.91; P < 0.00001), but reveals no obvious impact on adverse events (RR = 0.97; 95% CI = 0.91 to 1.03; P = 0.30) or serious adverse events (RR = 0.88; 95% CI = 0.49 to 1.60; P = 0.68).
Conclusions
Tralokinumab may be effective and safe to treat atopic dermatitis.

Engineering silk fibroin-based biomaterials with tunable functional properties is pivotal for the next generation of tissue engineering and regenerative medicine. We introduce a novel surface engineering technique that harnesses the unique chemistry of silk fibroin to fabricate films with controlled release of copper (II) ions (Cu2+), known to enhance wound healing processes. By employing a facile film-forming solution and subsequent modification with polydopamine (PDA), we developed silk fibroin (SF) films coated withCuNPs, termed SF-PDA-CuNPs (SPC). This innovative methodology is not only straightforward and reproducible but also effective in functionalizing silk fibroin. Our engineered SPC films demonstrate a slow and sustained release of bioactive Cu2+ for a marked acceleration in wound closure of living mammalian cells. These findings underscore the potential of Cu2+-loaded SF films as a novel strategy for enhancing wound repair, opening new avenues for the application of silk fibroin in advanced wound care solutions.

In this study, a lever was designed for manual shelling of maize. The lever is made up of a 30 mm diameter rod with a 10 mm diameter hole drilled at one end and a 20 mm diameter rod welded vertically to the rod, 400 mm from the other end. The maize ear is placed inside a 70 mm diameter tube before shelling and when the lever is pushed the maize ear is forced through the shelling tube, and in the process the seeds fall off the cob. Explicit Dynamic Analysis of the lever done in Ansys showed that the lever will effectively shell maize ears without damage to both seed and cob. Results of the Analysis gave 0.26485 m and of -9.7419e− 8 m as maximum and minimum values of directional deformation, 76386 Pa and 0 Pa respectively as maximum and minimum values of equivalent stress, 9,4005e− 6 m/m and 0 m/m as maximum and minimum values of equivalent strain, 29.507 m/s2 and 7e− 2 m/s2 as maximum and minimum values of total acceleration, and 21085 Pa and − 23604 Pa as maximum and minimum values of shear strain respectively. This study therefore develops and new and cost-effective means of shelling maize ears which requires neither electricity nor any sort of fuel to operate.

Published: January 2024

Currently Seismic impacts getting very serious concern when designing multi-storied reinforced concrete structures. Seismic tremors have occurred in numerous parts of the globe. High-rise structures should have proper stiffness to resist lateral loads caused by Earthquakes and Winds. Consequently, Engineers are extremely concerned about finding suitable solution that will allow structures to survive without major damage. Shear walls are structural members which are designed to carry earthquake loads and opposes lateral loads significantly. They are good choice to increase stiffness of high-rise structures. This paper aims to use shear walls in various location of a G+13 multi-storied residential building and to determine the best shear wall placement in high slender building by analyzing storey displacement, storey drift, base shear and fundamental time period in various seismic zones according to IS 1893:2016. Three models are prepared and compared under different seismic zones. Shear walls at core of building, shear walls at four corners of building and the combination of both. Our study's goal is to test a structure's ability to bear lateral load applied to it according to Code and also when it exceeds the limit of allowable deformation. The prepared model for this experimentation is considered to be located on medium soil and wind velocity is high like 148mph. The experiment concluded that, building with shear wall combination of both core and corner will show better result to resist lateral forces though the combination isn’t enough to help withstanding the high slender structure against very powerful earthquake attack like Zone-v.

Published: January 2024

The advancement of Human-Robot Collaboration (HRC) in industrial environments has underscored the importance of establishing harmonious and symbiotic relationships between humans and robots. This study, in line with the principles of Industry 5.0, proposes an approach to support the integration of human capabilities with advanced robotics, enhancing collaborative productivity and fostering a paradigm shift towards a more interactive and beneficial human-robot symbiosis. Prior research has established the basic principles of Symbiotic Human-Robot Collaboration (SHRC), but has often neglected the critical problem of how to conduct collaborative tasks to exploit the potential of these symbiotic interactions. This paper presents a novel methodology to support the design of protocols for collaborative tasks, with the aim of promoting positive symbiotic interactions between humans and collaborative robots. The focus is on developing tasks that naturally integrate positive symbiotic interactions, which involves determining task performers and optimizing the mutual benefits derived from task execution. A case study is presented to illustrate the practical application of this methodology in a real-world context.

Despite decades of research, questions remain about the persistence of neutralising antibodies (nAb) and serological correlates of polio vaccine efficacy. In a cross-sectional study among 299 children in Hong Kong, we estimated that the mean nAb titres against polioviruses type 1, 2 and 3 (PV1, PV2 and PV3) one month after receiving the 4th dose of inactivated polio vaccine (IPV) at 19 months of age were 2,068 (95% credible interval: 1,517 – 2,864), 4,705 (3,439 – 6,436) and 2,758 (1,894 – 4,086), but declined substantially in 4 years to 268 (222 – 325), 751 (630 – 900), and 411 (323 – 521), respectively. Administration of the 5th dose of IPV restored nAb titres among children aged 6-7 years, and the decline in nAb titres was slightly slower with the estimated mean titres of 355 (272 – 462), 538 (427 – 681), and 548 (378 – 786) against PV1, PV2, and PV3 at 4 years post the 5th dose. We estimated that the proportion of children who were seroprotected against PV1, PV2 and PV3 would drop below 90% at: (i) 8.2, 10.8, 8.7 years after the 4th dose; and (ii) 11.6, 11.2, 11.0 years after the 5th dose, highlighting the importance of maintaining populational immune persistence at high nAb levels.
