Authors: Karimah Fatimah Isyti , Rusmana Dadan , Rahtikawati Yayan
Published: November 2022

Perempuan dipandang sebagai makhluk yang inferior dibandingkan laki-laki. Posisinya sering terpinggirkan dalam segala aspek kehidupan manusia. Bahkan agama menjadi salah satu dasar untuk menempatkan perempuan di bawah laki-laki. Hal ini terlihat dalam beberapa tafsir klasik yang pengarangnya adalah laki-laki. Amina Wadud dan Zaitunah Subhan adalah dua tokoh perempuan yang merasa ketidakadilan terhadap perempuan di sekitarnya harus dihilangkan. Penelitian ini bertujuan untuk mengkaji perbandingan metodologi tafsir Zaitunah Subhan dan Tafsir Amina Wadud dalam mengkaji masalah “Perempuan”. Metode yang digunakan dalam penelitian ini adalah deskriptif-analisis. Hasil penelitian ini adalah sebagai berikut: Secara umum metodologi Tafsir Zaitunah Subhan dan Tafsir Amina Wadud menggunakan metode maudhu'i, karena sama-sama fokus membahas tema-tema tertentu. Namun dalam proses analisisnya, Tafsir Zaitunah Subhan menggunakan metode tafsir maudhu'i dengan mengacu pada tiga kitab utama dari tiga generasi, yaitu Tafsir Al-Qur'an karya Ibnu Katsir, Tafsir Al-Azhar karya Hamka dan Al-Qur'an dan terjemahannya. Sedangkan Tafsir Amina Wadud menggunakan model interpretasi hermeneutik.

Published: November 2022

Se midieron seis rasgos funcionales del tallo y hoja de especies que tuvieran diámetros basales mayores o iguales a 5 cm, en ocho parcelas permanentes con coberturas arbustivas sucesionales, en la Cordillera Oriental de Colombia, para describir sus comportamientos funcionales. Para cada rasgo se obtuvieron frecuencias de distribución y correlaciones que permitieron determinar estrategias de tipo adquisitivo y conservativo. La mayoría de las 45 especies registradas tenían hojas pequeñas, área foliar específica baja, asimilación fotosintética máxima baja y altura máxima baja; la densidad de madera más frecuente estaba centrada en la mediana de la distribución. No hubo correlación entre los rasgos foliares y la densidad de madera o la altura máxima. Nueve  especies tenían rasgos adquisitivos, con altas tasas de asimilación fotosintética máxima, alta área foliar específica, bajo contenido foliar de materia seca y baja densidad de madera. Por el contrario, 36  especies con rasgos conservativos mostraron bajas tasas de asimilación fotosintética máxima, baja área foliar específica, alto contenido foliar de materia seca y densidad de madera media.

Esta investigación tuvo como objetivo realizar un estudio prospectivo del sector del deporte que facilite el diseño de escenarios futuros desde la perspectiva de los actores y el análisis de los futuros plausibles, que permitan alcanzar la apuesta competitiva del deporte para el municipio de Guadalajara de Buga, Colombia. Se utilizó una metodología de tipo descriptiva, teniendo como unidad de análisis el sector del deporte del municipio, aplicando herramientas de la prospectiva: Delphi, Abaco de Regnier, MIC-MAC y Morphol. Como resultado se identificaron tres escenarios futuros: optimista, pesimista y retador, los cuales entrevén una visión estratégica para el horizonte en el 2030. Todo esto compone un insumo importante que contribuye al sector y sus actores para la toma de decisiones, determinación de acciones y recursos clave para la definición de una agenda prospectiva, que impacte positivamente el deporte formativo y competitivo en este municipio, mejorando su posicionamiento a nivel nacional e internacional. Los resultados muestran, entonces, una orientación a priorizar aquellos factores que mejoren las condiciones organizacionales, políticas, económicas y sociales, pues aquellos factores que aparecen en la extrapolación de manera desfavorable son considerados por los actores como los más retadores y resistentes al cambio, puesto que corresponden a centros de poder y decisión que escapan de su voluntad, mientras que los factores más favorables, son considerados deseados y podrían incidir, es decir, son posibles y realistas.
Equilibrio trabajo-vida y su relación con la salud mental en trabajadores de diferentes profesiones: una revisión sistemática
Authors: Ramírez-Angel Lina María , Riaño-Casallas Martha Isabel
Published: November 2022

La globalización y la búsqueda de la eficiencia organizacional han desdibujado la línea que equilibra el trabajo y la vida personal. Cada vez es más difícil separar los roles y evitar extender los horarios laborales, lo cual puede conllevar a una sobreexposición de factores de riesgo psicosocial, afectando la salud mental de los trabajadores e incrementando costos para las organizaciones. El objetivo del artículo es caracterizar la relación existente entre el equilibrio, vida laboral y personal —WLB, por sus siglas en inglés Work-Life Balance— y la salud mental de los trabajadores —estrés, depresión, ansiedad, burnout, angustia y fatiga—, para lo cual se realizó una revisión sistemática de la literatura, y mediante el análisis de 43 estudios se logró aclarar el concepto del WLB. Se presentaron los hallazgos generales sobre la relación WLB y salud mental, y se analizó el contexto de los estudios haciendo énfasis en sectores u ocupaciones. Así, se concluye que algunos estudios no se centran verdaderamente en el WLB, ya que prefieren enfocarse en la perspectiva negativa —conflicto —, y en el caso de la salud mental los estudios se centran en los síntomas de la enfermedad. En otros hallazgos, se determinó que no hay consenso en resultados por género, ni frente al impacto de la flexibilización laboral en la relación —WLB y la salud mental—. En lo metodológico, la mayoría de estudios analizados son cuantitativos, transversales y con muestras homogéneas, que contemplan la perspectiva individual —autoinforme— y tan solo uno estudia las condiciones de trabajo.
An Inca Tern in the Hawaiian Islands: First Record for Hawaii and the United States
Authors: VanderWerf Eric A.
Published: November 2022

An Inca Tern (Larosterna inca) was observed and photographed at several locations in the Hawaiian Islands from 10 March 2021 to 8 January 2022, constituting the northernmost and westernmost record for this species, which breeds on the Pacific coast of South America, and the first for the United States. Here I provide details about the appearance and inter-island movements of this individual, along with evidence indicating that only a single individual was involved in all sightings. The Hawaiian Islands occurrence, along with recent documentation of the Inca Tern in Central America north to Guatemala, points to yet another South American seabird moving north with increasing frequency in the Pacific Ocean.

Published: November 2022

Landfills have been identified as one of the main threats to wildlife, such as amphibians, since landfills as they contaminate the aquatic and terrestrial habitat and act as stressors, negatively affecting the development and morphology of amphibians. However, few studies have been realized to know the morphological variation of anurans under environmental disturbances. In this study, we compared the morphological patterns of Rhinella marina in contrasting habitats: a temperate forest and a landfill, in the San Martín de las Cañas dam, Jalisco, Mexico. We analyzed morphology, body traits size and allometric patterns. The Body shape of the landfill toads was more elongated and thinner than that of the forest toads. We found that toads from the forest had greater sizes in most of the morphological traits in comparison to toads from the landfill. Allometric patterns showed that most of the morphological characters had a negative allometric patterns in many traits in toads from both conditions. Rhinella marina has showed affinity for disturbed areas or sites around human settlements, and persists in habitats altered by urbanization. However, our results showed an increase in stress levels in toads that inhabit landfills.
Using Machine Learning Models for Predicting Culex Mosquito Habitats and Breeding Patterns in Washington D.C.
Authors: Xia Iona , Singirikonda Neha , Hellman Landon , Watson Jasmine , Hanna Marvel
Published: November 2022

Culex mosquitoes pose a significant threat to humans and other species due to their ability to carry deadly viruses such as the West Nile and Zika. Washington D.C., in particular, has a humid subtropical climate that makes it ideal as a habitat for mosquito breeding. Thus, tracking mosquitoes’ habitats and breeding patterns in Washington D.C. is crucial for addressing local public health concerns. Although fieldwork techniques have improved over the years, monitoring and analyzing mosquitoes is still difficult, dangerous, and time-consuming. In this work, we propose a solution by creating a Culex mosquito abundance predictor using machine learning techniques to determine under which conditions Culex mosquitoes thrive and reproduce. We used four environmental variables to conduct this experiment: precipitation, specific humidity, enhanced vegetation index (EVI), and surface skin temperature. We obtained sample data of these variables in the Washington D.C. areas from the NASA Giovanni Earth Science Data system, as well as mosquito abundance data collected by the D.C. government. Using these data, we created and compared four machine learning regression models: Random Forest, Decision Tree, Support Vector Machine, and Multi-Layer Perceptron. We searched for the optimal configurations for each model to get the best fitting possible. Random Forest Regressor produced the most accurate prediction of mosquito abundance in an area with the four environment variables, achieving a mean average error of 3.3. EVI was the most significant factor in determining mosquito abundance. Models and findings from this research can be utilized by public health programs for mosquito-related disease observations and predictions.

The article explores the nexuses between carbon dioxide (CO2) emissions, economic growth, renewable energy consumption, and trade openness in the fast-growing MINT (Mexico, Indonesia, Nigeria, and Turkiye) and BRICS (Brazil, Russia, India, China, and South Africa) economies for the period 1990–2019. The study utilized threshold regression to provide a policy threshold on carbon emission metrics tons per capita of 0.96, 0.36, for the fast-growth emerging markets. The study also provides complementary thresholds for renewable energy consumption and trade policies. The novelty of the study is in the light of the contemporary literature that stems from the premised on providing the policymakers in the fast-growing economies with avoidable policy thresholds for CO2 emission along with the complementary thresholds on renewable energy consumption, and trade policies in the nexus between green growth and environmental degradation.
Carbon-dependent net-zero emission energy systems without reliance on fossil fuels and bioenergy

Published: November 2022

Existing climate change mitigation scenarios for attaining the 1.5°C goal generally phase out hydrocarbon use through decarbonization of the energy system to eliminate fossil fuel usage. However, they require rapid changes in energy-demand technologies and human behaviors or extensive reliance on bioenergy for carbon dioxide removal (CDR). Carbon capture and utilization (CCU) presumably could support to alter such energy systems, considering recent technological advancements in direct air capture (DAC) and renewable-based hydrogen. Here, we developed a CCU-based scenario under the 1.5°C climate goal using a global energy system model. In the scenario where CCU is mainly introduced by limiting demand-side electrification, bioenergy, and CDR, CCU-based synthetic fuel reaches 30% of global energy demand to achieve net-zero emissions by 2050. In contrast to existing 1.5°C scenarios, this CCU scenario is characterized by greater availability of hydrocarbons in energy demand, reaching 280 EJ in 2050, whereas fossil fuel and bioenergy supplies decrease to 60 EJ and 100 EJ, respectively. Despite moderate demand-side electrification, this scenario involves rapid upscaling of renewable energy and DAC, which reach 600 EJ and 10 Gt-CO2 per year by 2050, respectively. While the CCU-based scenario involves multiple challenges on energy supply transformation and associated energy investments, it provides an alternative mitigation option that considers the difficulties in rapid demand-side changes and the risks of bioenergy and CDR.

Authors: Luo Feng , Jiang Jiapei , Yang Linxin , Liang Yan , Cao Yuan , Zhou Xuexiao , Wan Qianbing
Published: November 2022

Background: Students' internship year is critical for dental interns to develop the skills and knowledge to perform complete denture rehabilitation (CDR). Online learning is recommended because students can't go to the clinic with the outbreak of COVID-19. This study aims to assess students' intentions toward online learning to improve teaching quality and ensure students master the CDR.
Methods: A questionnaire-based online survey was conducted to evaluate internship students’ background and attitudes to online learning of CDR. The questionnaire consists of three parts and 20 structured questions regarding students’ experience with online learning, students’ knowledge background about CDR, and students’ attitude about online learning CDR. 63 dental interns, including 19 male and 44 female undergraduate dental students, participated in this survey.
Results: 93.65% of the 63 students have participated in online learning, 76.19% believe it is necessary to provide online instruction, and 80.95 % plan to join in the future. 71.42% of the students think they are ready for online learning on CDR. Then, we evaluated students’ knowledge background about CDR. Survey results indicate most students believe they are unprepared to perform CDR in the clinic and only a small percentage of students are familiar with the diagnosis, treatment process, and operation of CDR. Fortunately, interns are incredibly optimistic about the prospect of learning complete dentures online. According to our survey, 60.90% of students enjoy learning online, 71.43% are motivated to continue online learning, and 82.54% believe online learning of CDR is helpful.
Conclusion: According to the survey results, adopting online learning may be a practical solution to guarantee students' quality of oral clinical placements and address the growing shortage of clinical placement opportunities worldwide. Furthermore, the effectiveness and efficiency of online learning need to be further evaluated to ensure they can enhance dental interns’ knowledge level and practical ability of CDR.
Purna River Pirated by a Lineament and Converted its Path into Paleochannel
Authors: siyol laxman , ROJH B.R , Jakhar S.R
Published: November 2022

A paleochannel of the Purna River basins in the basaltic terrain in the proximity of the village- Daher, and Uga, in Subir Taluka, in the Dang district of Gujarat was discovered by the first author. The discovery of paleochannel is based on a study of satellite imagery, the presence of perennial water springs, and the presence of dense trees with green leaves during summer close to the Purna River. With the help of satellite imagery and ground check, a lineament wasdiscovered near the Purna River paleochannel, which was later renamed as village Girmal- Pipalpada lineament, after the village in which it was found. The total length of this lineament is approximately 22km and the Purna River flows through this lineament for about 1.4km,the Purna River is pirated by this lineament. Due to this piracy of the Purna River, its crescent-shaped old path with the passage of time was converted into a paleochannel. The paleo course of the river is clearly visible in the satellite imagery. This paleo river channel is a good site for sustainable groundwater sources. Presently two open wells are dug in this paleochannel supplying water to four villages. Surprisingly,there is very less depletion of pumping water level (PWL) in the well because of the continuous charging of open wells by this paleochannel.
Children with mild hyponatremia at the emergency department are at higher risk of more severe infections and hospitalization.
Authors: Pintaldi Stefano , Zago Alessandro , Pizzolon Carlo , Magni Elena , Cozzi Giorgio , Andrade Stefanny , Barbi Egidio , Amaddeo Alessandro
Published: November 2022

Background
Mild hyponatremia is frequently encountered in the pediatric emergency department (PED). Although it is usually of little clinical concern, its prognostic meaning as a possible marker of more severe disease is not well established.
Methods
We retrospectively analyzed data from children and adolescents who performed a blood sample with plasmatic sodium measurement on admission to PED of IRCCS "Burlo Garofolo" Pediatric Hospital in Trieste, Italy, in 2019. We compared the clinical and laboratory characteristics of patients with hyponatremia to those with normal sodium.
Results
Among 807 subjects, hyponatremia (sodium < 135 mEq/L) was present in 17.6%, being mild (134 − 130 mEq/L) in 16.5%. Hyponatremic patients were younger, more frequently males, with an infection diagnosis, mainly of the respiratory tract and of viral aetiology. They presented higher C-reactive protein (CRP) levels and erythrocyte sedimentation rates (ESR). Compared to normonatremic individuals, hyponatremic patients presented a higher risk of an underlying infection (aOR 2.02; 95%CI 1.33–3.08), higher risk of hospital admission (aOR 1.72; 95%CI 1.06–2.48), and a longer hospital stay (aOR 1.99; 95%CI 1.03–3.85). When considering only subjects with mild hyponatremia, we found similar results.
Conclusion
Hyponatremia and mild hyponatremia in the PED are associated with an increased admission rate and longer hospital stay. Mild hyponatremia should be considered a warning sign for a possibly more relevant condition.

Background Human immunodeficiency Virus (HIV) and consequently the acquired immune deficiency syndrome (AIDS) remain a significant public health problem, having claimed 36.3 million lives so far. In 2020, approximately 680,000 people died from AIDS-related illnesses worldwide. Despite increased access to antiretroviral treatment (ART), the burden of mortality and morbidity due to advanced HIV disease (AHD) has not significantly changed over the years. AHD individuals are more prone to opportunistic infections– includingMycobacterium tuberculosis(MTB) andCryptococcal meningitis(CM). CM has been reported as a significant cause of mortality among people living with HIV (PLHIV), accounting for 15% of the global AIDS-related deaths in 2019. To keep track of the global commitments made by governments to end the AIDS epidemic as a public health threat by 2030, knowledge of the burden of AHD and its risk factors are essential. Methods A hospital-based cross-sectional study was conducted from February 2020 to February 2021. HIV-infected individuals on ART at the Buea Regional Hospital were screened for AHD using World Health Organization (WHO) consolidated guidelines. A pre-tested semi-structured questionnaire was administered to the consented participants, and blood, sputum, and urine samples were collected. Acid fast bacilli microscopy detection and TB culture were carried out following standard microbiological procedures. Cryptococcus antigen lateral flow tests were performed using sera. Chi-square and regression analysis were carried out on SPSS at a p < 0.05 significance level. Results From a total of 3,229 PLHIV adults on care in the study period, 327 (10.1%) were suspected of having AHD, and were enrolled in the study. Most of the enrolled individuals were women (62.4%) and the mean age of the participants was 40.5 ± 24.7 years. A total of 130 (39.8%, [95% CI, 34.41–45.29]) participants presented with AHD and 41 (35.7%, [95% CI, 26.94–45.12]) and 7 (6.7%, [95% CI, 2.72–13.25) had TB and Cryptococcal infections, respectively. AHD was associated with male gender (aOR; 3.9, 95% CI; 1.40–11.70), and being on ART for more than 12 months was protective (aOR; 0.1, 95% CI; 0.01–0.35). Conclusion Even when ART uptake has dramatically improved in Cameroon, AHD (35.7%) is far beyond the UNAIDS reduction target of 10% by 2020 and thus, improvement in the management of PLHIV is warranted.

According to the characteristics of rotary direct drive electro-hydraulic pressure servo valve, the lumped parameter modeling and three-dimensional (3D) field analysis methods are integrated. The lumped parameter method is used for mathematical modeling for system parts with clear physical concept, and for complicate structures difficult to simply and derive, the 3D mathematical model is employed to analyze the magnetic field, flow field and structural field. Moreover, numerical fitting is carried out to the field analysis results, and the model recognition methods, such as neural network, are used for modeling. Specific mathematical algorithms are used to represent the mathematical relationship between the input parameters (such as structural parameters and environmental parameters) and the feature output parameters. Finally, the algorithm which can be used to evaluate the relationship between the input parameters (such as structural parameters and environmental parameters) of the analyzed object and its static and dynamic performances is obtained. For similar research objects, the user only needs to change the values of input parameters to complete the analysis and evaluation of the static and dynamic performances of system.

Authors: Çallı Ümit , Çoban Fatih , Sevimli Neslihan
Published: November 2022

Background
To evaluate the the effects of seasonal allergic counjunctivitis (AC) and its treatment upon choroidal structure such as choroidal thickness (ChT) and choroidal vascular index (CVI) through the use of topical antihistamine agents.
Methods
The 60 eyes of 30 patients were included in the AC group. Another 30 patients were included in the control group. The choroid was imaged by using enhanced depth imaging optical coherence tomography (EDI-OCT) instrument without pupillary dilation. ChT was defined as the area between the outer hyperreflective border of the RPE and the sclerochoroidal border at the fovea, 750 µm temporal to the fovea and 750 µm nasal to the fovea. Image J was used to measure CVI. With the images obtained from EDI-OCT, the total choroidal area (TCA), luminal area (LA), stromal area (SA), and CVI were calculated using the binarization method.
Results
The mean ChT value in the AC group was 358.5 ± 93.8 µm at baseline and 356.8 ± 86.6 µm following 1 month of treatment. Meanwhile, the mean ChT in the control group was 316.6 ± 60.7 µm. The mean CVI value was 66.65 ± 2.98 in the control group, 70.75 ± 3.26 in the AC group at baseline, and 69.50 ± 3.17 following 1 month of treatment. Statistically significant difference was tracked between control and AC group (p = 0.028) and control group and posttreatment values (p = 0,031). There were no statistically significant difference between initial AC treatment values and posttreatment values for all of the measurements.
Conclusions
ChT and CVI can increase in patients with AC due to inflammation and increased vascular permeability. Although symptoms and signs related to AC may disappear after the treatment, effects in the choroid do not immediately normalize.

Purpose

This study aims to compare the clinical outcomes between a superficial quadriceps autograft and a hamstring autograft.

Methods

A total of 47 consecutive patients with patellar instability, who underwent QA and HA for patellar stabilization at a specified center between 2012 and 2020, were retrospectively reviewed. The final radiographic and outcome measurements included; the knee’s range of motion and the Kujala and Lysholm scores were reviewed and analyzed with a minimum follow-up period of 12 months.

Results

22 QA and 25 HA patients met the eligibility criteria. There were 50% of males and females with a median age of 25 years (range 12–58) in the QA group, while 40% were males with a median age of 25 years (range 14–51) in the HA group. The mean follow-up period was 38.4 months (range 12–70) in QA and 59 months (range 16–96) in the HA group. At the final follow-up, no complications were observed with either technique. No patients presented with recurrent dislocations or subluxations after surgery. There was no statistically significant difference in postoperative mean Kujala scores (QA = 94.6 +/- 4.1 and HA = 94.0 +/- 7.6, p = 0.36) or the mean Lysholm scores (QA = 93.9 +/- 4.9 and HA = 93.0 +/- 6.6, p = 0.30).

Conclusion

MPFL reconstruction for patellar instability surgery using either QA or HA achieved good clinical outcomes during a minimum follow-up of 1 year. No significant differences in clinical outcome scores were observed in both groups.

Three-dimensional (3D) ceramic network has advantages over conventional ceramic nanoparticles in achieving high-performance flexible polymer dielectrics. However, the energy storage capacity cannot be substantially improved due to the relatively large dielectric loss and low breakdown strength. In this study, hierarchical 3DBT/EP-GO (GEBT) dielectric hybrid composites with greatly improved permittivity and energy storage density were obtained by reversely introducing the mixed graphene oxide (GO)/epoxy (EP) solution into three-dimensional BaTiO3 (3DBT) network, which was facilely constructed by sol-gel method using cleanroom wiper as template. A relatively high dielectric constant (ε′ = 15.6) and breakdown strength (E0 = 239.8 kV·mm− 1) were simultaneously achieved for the GEBT-4 system with ~ 15.4 wt% of 3DBT and 0.75 wt% of GO (to the epoxy), which were much superior to the GEBT-1 with only 15 wt% 3DBT (ε′ = 9.2, E0 = 128.8 kV·mm− 1) and epoxy nanocomposite with even 25 wt% BT nanoparticles (ε′ = 6.3, E0 = 121.0 kV·mm− 1). The continuous 3DBT ceramic network provided effective polarization pathway within epoxy matrix, while GO was helpful to prevent electrical breakdown of composites, thereby resulting in the significantly enhanced energy storage performance.
Mathematical model and a block-centered difference approximation for a semiconductor device problem with heat and magnetic influences *
Authors: Yirang Yuan , Changfeng Li , Yunxin Liu
Published: November 2022

In this paper, we present a mathematical model with initial-boundary values and a block-centered approximation for a new semiconductor device type. Two factors, heat and magnetic influences are considered. This discussion is an important and basic simulation problem in information science. The mathematical model is formulated by four nonlinear partial differential equations (PDEs), determining four major physical variables. An elliptic equation is given for the potentials, two convection-diffusion equations are for the concentrations of electronic and hole, and a heat equation is for the temperature. The potentials affects the whole physical movement. The elliptic equation is treated by a block-centered method, and the law of conservation is preserved. The computational accuracy is improved one order. Other equations are convection-dominated, thus are approximated by block-centered differences. Furthermore, the unknowns and adjoint functions are computed at the same time. These characters play important roles in numerical computations of conductor device problems. Using the theories of priori analysis such as energy estimates, the principle of duality and mathematical inductions, an optimal estimates result is obtained. Thus, this important problem is solved.
