Factors Affecting the Fairness of China s Tutoring After
the Implantation of Double Reduction Policy
Authors: Bao Xinwei
Published: November 2024

Chinese government introduced the double reduction policy, advocating the elimination of exams and written assignments for the
first and second graders of primary school and closing down numerous extracurricular tutoring institutions to reduce the burden of students in
primary school and middle school. The double reduction policy has reduced students homework time and regulated the chaotic proliferation of inadequately qualified tutoring institutions in the market. However, the double reduction has not narrowed the disparities caused by
extracurricular tutoring. This paper demonstrates how family background and teacher attention influence the distribution of educational opportunities. This paper suggests that society can enhance education equity by respecting children s desire for free development, enabling teachers
to provide personalized instruction to meet student needs.

La conectividad forestal en el Parque Nacional Natural Alto Fragua Indi Wasi de la región andino-amazónica de Colombia
Authors: Castro Carlos Fabio , Rosas Patiño Gelber
Published: November 2024

El Parque Nacional Natural Alto Fragua Indi Wasi (PNNAFIW) está constituido por un tipo de bosque crucial para la región andino-amazónica debido a su función como ecotono de transición altitudinal que beneficia la biodiversidad. A pesar de su estatus de área protegida, la intervención humana ha afectado su conectividad forestal. Esta investigación se enfocó en analizar el impacto de las acciones humanas en la conectividad forestal del bosque utilizando datos de cobertura de tierra y un enfoque basado en patrones morfológicos espaciales. Se evaluaron los cambios en el bosque y la conectividad durante los periodos 2002, 2007, 2012 y 2018, considerando la influencia histórica de los agentes humanos en la zona. Los resultados revelaron que la creación de áreas protegidas contribuye a mantener y restaurar los hábitats forestales. Por otro lado, la expansión de cultivos ilícitos y la colonización tienen un impacto negativo en la conectividad, especialmente en el patrón núcleo. El estudio identificó dos áreas adyacentes con diferencias significativas en la afectación de la conectividad forestal: el PNNAFIW, con baja afectación, pero con intrusiones agropecuarias localizadas, y el sector de piedemonte, donde la presión humana ha llevado a una disminución de los hábitats. La creación del PNNAFIW se destacó como un factor positivo para la conservación del bosque y la conectividad forestal. En esta investigación se destaca la importancia de considerar los procesos históricos de poblamiento y ocupación como factores clave que pueden influir en la conectividad forestal en áreas protegidas como el PNNAFIW.

Computational and Experimental Studies on the Behaviour of Spray with Different Orifice Characteristics and Fuel Properties of Biodiesel Crude Palm Oil (CPO) on a Premix Injector – A Comprehensive Review
Authors: Chin Ronny Yii Shi , Didane Djamal Hissein , Khalid Amir
Published: November 2024

The search for higher energy efficiency of industrial-scale burners to attain low emission especially Nitrogen Oxide (NOx) has demanded experimental studies that are complemented with Computational Fluid Dynamics (CFD) simulations. While there exist numerous emission control techniques, the passive control technique was the main focus of the present review study. Biodiesel fuel crude palm oil (CPO) was found to reduce emission components, particularly carbon components and particulate matter (PM). Biodiesel CPO has the capability to mitigate cavitation inside the injector’s orifice which contributes to damage reduction on the orifice. Moreover, although cavitation can improve spray atomization and produce finer spray droplets, it also causes damage to the orifice of injectors. Orifice characteristics such as orifice’s diameter and pattern can also reduce cavitation inside the orifice. Orifice’s pattern is divided into cylindrical shape orifice and conical shape orifice. The conical orifice is found to reduce the cavitation inside the orifice while cylindrical orifice was indicated as a highly cavitating orifice. Alternatively, as rapid swirling motion is capable to enhance the fuel and air mixing, a new concept of swirling fuel-air premix inside the injector is invented and it is proven to reduce emissions. It was, however, learned that spray characteristics are still playing an important role in the prediction of combustion performance, particularly droplets Sauter Mean Diameter (SMD) which is a worldwide parameter that needs further investigations in order to predict the fineness of spray production and combustion.
Design Optimization of a Parallel-Serial Manipulator Considering Stiffness Criteria
Authors: Antonov Anton
Published: November 2024

In this paper, we analyze stiffness and perform geometrical optimization of a parallel-serial manipulator with five degrees of freedom (5-DOF). The manipulator includes a 3-DOF redundantly actuated planar parallel mechanism, whose stiffness determines the stiffness of the whole mechanical system. First, we establish the kinematic and stiffness models of the mechanism and define its stiffness matrix. Two components of this matrix and the inverse of its condition number are chosen as stiffness indices. Next, we introduce an original two-step procedure for workspace analysis. In the first step, the chord method is used to find the workspace boundary. In the second step, the workspace is sampled inside the boundary by solving the point-in-polygon problem. After that, we derive stiffness maps and compute the average stiffness indices for various combinations of design variables. The number of these variables is reduced to two geometrical parameters, simplifying the representation and interpretation of the obtained results. Finally, we formulate the multi-objective design optimization problem, whose main goal is to maximize the lateral stiffness of the mechanism. We solve this problem using a hierarchical (ε-constraint) method. As a result, the lateral stiffness with optimized geometrical parameters has increased by 54.1 % compared to the initial design.
Tunable Sub-THz and THz Lasing Effect Using FETs at Room Temperature
Authors: Elkhatib Tamer
Published: November 2024

I report on the first observed self-amplification by stimulated emission of 0.2THz and 1.63THz radiation using InGaAs/GaAs HEMT operating in the deep saturation regime at room temperature. I demonstrate both theoretically and experimentally that the Sub-THz and THz FETs response is due to rectification of the nonlinear dependence of the device current-voltage characteristics. FETs do operate as a nonlinear THz mixers and rectifiers and its open-drain responsivity is given by a similar expression to that of zero-bias Schottky diode detector. However, operating FETs deep in the saturation regime does allow the accurate tuning of the device to the resonance condition or the negative resistance mode at room temperature, hence FETs can be tuned in the deep saturation regime to enable sub-THz and THz lasing effect. This observed sub-THz and THz laser phenomena using FETs will revolutionize human technology in all fields of life in the near future.

The subject matter of the study in the article is the method for approximating the convolutional operator for edge detection using a genetic algorithm for segmentation of complex-structured images. The goal is to develop a method for approximating the convolutional operator for edge detection using a genetic algorithm for the segmentation of complex-structured images. The tasks are: analysis of known methods of segmentation of optoelectronic images, development of a method for approximating the edge detection convolutional operator using a genetic algorithm for segmenting complex-structured images, practical validation of the method for approximating the edge detection convolutional operator using a genetic algorithm for segmenting complex-structured images. The methods used are: digital image processing methods, data clustering techniques, matrix theory mathematics, swarm intelligence methods, the genetic algorithm, mathematical modelling techniques, optimization theory methods, as well as analytical and empirical methods for image comparison. The following results are obtained. The advantages and disadvantages of the main known methods for segmenting optoelectronic images have been identified. It has been established that the most effective segmentation methods for images from space-based optoelectronic observation systems (complex-structured images) are those based on swarm intelligence and genetic algorithms. An important case of segmentation – binarization (segmentation into two classes), has been considered. The task of binarization has been formalized, and the concepts of structural and amplitude predicates have been introduced. The method for segmenting complex-structured images has been improved, in which, unlike existing methods, a genetic algorithm is used for approximating the edge detection convolutional operator, facilitating segmentation of images at various scales with later integration of the results. A visual assessment of the quality of the segmented image has been conducted using the improved method. Conclusions. The method for segmenting complex-structured images has been improved, in which, unlike existing methods, a genetic algorithm is employed to approximate the edge detection convolutional operator, easing segmentation of images at various scales with later integration of the results. A visual assessment of the quality of the segmented image using the improved method shows a significant reduction in the number of noise objects present in the segmented image.

Sağlık Teknikerliği Öğrencilerinin İşitme Sağlığı ve Gürültüye Bağlı İşitme Kaybı Konusundaki Farkındalıklarının Belirlenmesi
Authors: Mungan Durankaya Serpil
Published: November 2024

Amaç: Küresel bir sorun olarak da kabul edilen Gürültüye Bağlı İşitme Kaybını (GBİK) önlemenin en etkili yollarından birisi bu konuda farkındalık oluşturmaktadır. İşitme sağlığı ve korunması odyoloji biliminin ilgi alanıdır. Çalışmanın amacı, sağlık teknikerliği bölümlerinde okuyan öğrencilerin işitme sağlığı ve işitme kaybını önleme konusundaki farkındalıklarını belirlemek, bu farkındalığın eğitim alanı ile ilişkisini ortaya koymaktır.
Gereç ve Yöntem: Çalışma kesitsel araştırma olarak planlandı. Araştırma kapsamında, 18-30 yaş arasındaki 219 sağlık teknikerliği öğrencisine gürültüye bağlı işitme kaybına yönelik farkındalıklarını ölçmek üzere 10 sorudan oluşan anket yapıldı. Katılımcılardan elde edilen bilgiler tanımlayıcı istatistik ile değerlendirildi. Odyometri teknikerliği ile diğer sağlık teknikerliği programları arasındaki farkın anlamlılığı için ki-kare analizi yapıldı.
Bulgular: Odyometri öğrencilerinin diğer sağlık teknikerliği öğrencilerine kıyasla tüm sorulara doğru yanıt verme oranı daha yüksekti. Ancak gürültünün işitmeye etkilerini sorgulayan sadece 4,5,6. sorularda istatistiksel olarak anlamlı farklılık elde edildi (p<0,05). GBİK’nın önlenebilir sorun olduğuna ve yüksek seslere maruz kalmanın işitme kaybına neden olabileceğine dair soruları öğrencilerin %76'sı doğru yanıtladı. Gürültüye bir defa maruz kalmanın işitme kaybı yaratmadığını düşünenlerin oranı %26,5 iken bu konuda bilgisi olmayan birey oranı %11 idi. Konser gibi yüksek gürültülü ortamlarda bulunmanın işitme kaybı yaratacağını düşünenlerin oranı %66,5 ile sınırlı kaldı. Kulak tıkacı kullanmanın müziği net duymayı engelleyeceği fikri ise %59,8 oranındaydı.
Sonuç: GBİK’den korunmanın önemli ve etkili yolu bu konuda farkındalık oluşturmaktır. Sağlık teknikerliği alanında okuyan üniversite öğrencilerinin gürültü ve etkileri konusunda bilgi eksiklikleri olduğu görüldü. Bu konuda farkındalık oluşturmanın yanında işitmeyi koruyucu önlemler hakkında eğitimlerin verilmesi küresel bir sorun olma potansiyeli taşıyan GBİK’nın önlenmesi açısından değerli olacaktır.

Hasta 77 yaşında hafif düzeyde Parkinson hastası (UPDRS:19) demansı olmayan ve yürüyüşte donma izlenmeyen erkek bir bireydi. Olguda son dönemde düşme hikayesi gözlenmemiştir. Olgu bir hafta içinde iki defa çalışmaya alınmış olup kendisinden en sevdiği müzik türü ve bu türe ait bir eser belirtmesi istenmiştir. Olgu ilk gün ritim belirleme için gerekli olan yürüyüş süresi ve adım sayısı ile ayrıca adım uzunlukları ölçülmüştür. İkinci görüşmede ise ritmik işitsel uyarım ve kişisel müzik tercihi ile ritmik işitsel uyarımın birleştirilmiş haliyle yürümüş ve sonuçlar tekrar ölçülmüştür. Bütün parametrelerde ritmik işitsel uyarım pozitif anlamda etkili olmuştur. Ritmik işitsel uyarım ve kişisel müzik tercihin birleştirilmesi ise ritmik işitsel uyarımın tek başına kullanılmasına göre daha etkili bir sonuç göstermiştir. Bu olgu çalışmasının sonucunda hafif düzeyde Parkinson hastalığı olan bireyde yürüyüşte akut iyileşme görülmüştür. Bu yaklaşımın etkinliğinin tam olarak belirlenebilmesi için daha fazla birey ve daha fazla zamana yayılan bir çalışma yapılması gerektiğini düşünmekteyiz.

Las amenazas ambientales, climáticas y ecológicas se han agudizado y representan ahora una triple crisis planetaria. Estas crisis interactúan entre sí y con las condiciones sociales del entorno, lo cual se traduce en un incremento de enfermedades crónicas, en el surgimiento de nuevas enfermedades y en el resurgimiento de otras. En este contexto, se requiere de la construcción de enfoques innovadores y holísticos de salud pública. Por lo anterior y con base en el diagnóstico global y nacional, proponemos una estrategia integral de salud planetaria que, desde la base comunitaria, atienda las sindemias resultantes de la interacción sinérgica de las amenazas ambientales, climáticas, ecológicas y sociales. Dicha estrategia se enriquece con una perspectiva en derechos humanos y se fortalece con un novedoso esquema para la formación de recursos humanos de alta calidad, tanto a nivel de educación superior y posgrado, como para el incremento de capacidades del talento local. Se plantea finalmente afrontar los determinantes sociales y ambientales desde la salud en función de proteger los derechos de la naturaleza. Así pues, se propone una agenda nacional basada en la acción interinstitucional y la creación de un programa nacional con estructura y presupuesto propios, y con un consejo científico asesor.
Active Disruption Avoidance and Trajectory Design for Tokamak Ramp-downs with Neural Differential Equations and Reinforcement Learning
Authors: Wang Allen , So Oswin , Dawson Charles , Garnier Darren , Rea Cristina , Fan Chuchu
Published: November 2024

The tokamak offers a promising path to fusion energy, but disruptions pose a major economic risk, motivating advances in disruption avoidance. This work develops a reinforcement learning approach to this problem by training a policy to safely ramp-down the plasma current while avoiding limits on a number of quantities correlated with disruptions. The policy training environment is a hybrid physics and machine learning model trained on simulations of the SPARC primary reference discharge (PRD) ramp-down, an upcoming burning plasma scenario which we use as a testbed. To address physics uncertainty and model inaccuracies, the simulation is massively parallelized on GPU with randomized parameters during policy training. The trained policy is then transferred to a transport simulator where it successfully ramps down the plasma. We directly address the crucial issue of safety criticality by demonstrating that a constraint-conditioned policy can be a trajectory design assistant that designs a library of feed-forward trajectories to handle conditions and user settings, a promising approach for the safety-critical context of burning plasma tokamaks. Finally, we demonstrate that the training environment can be a useful platform for other feed-forward optimization approaches by using an evolutionary algorithm to optimize feed-forward trajectories that are robust to physics uncertainty.

Background
The incidence of depression among college students is increasingly high, significantly impacting their daily lives. This study aims to utilize electroencephalography (EEG) to assess the effects of varying intensities of single-session aerobic exercise on depression symptoms in college students.
Objective
This study aimed to explore the effects of single sessions of aerobic exercise at varying intensities on depressive symptoms in college students through changes in BDI-II (Beck Depression Inventory-II) scores and resting-state EEG lateralization.
Methods
Depressed college students were randomly assigned to low, moderate, high-intensity exercise, and control groups. The study investigated the relationship between BDI-II scores and resting-state EEG frontal cortex lateralization and the impact of single sessions of aerobic exercise at different intensities on depressive symptoms.
Results
BDI-II scores were negatively correlated with frontal α2 (P < 0.01) and β1 (P < 0.05) lateralization in depressed students. Low-intensity exercise significantly reduced BDI-II scores (P < 0.05). Moderate-intensity exercise resulted in significant changes in BDI-II scores (P < 0.001), α2 lateralization (P = 0.002), and β1 lateralization (P = 0.006). Post-test comparisons showed significant differences in BDI-II (P = 0.048), α2 (P = 0.002), and β1 (P = 0.041) compared to the control group, and differences in α2 (P = 0.021) and β1 (P = 0.041) compared to the low-intensity group. High-intensity exercise also significantly altered BDI-II scores (P < 0.001) and α2 (P = 0.035). Post-test comparisons showed differences in BDI-II compared to low-intensity (P < 0.001), moderate-intensity (P = 0.01), and control groups (P < 0.001), and differences in α2 compared to the control group (P = 0.011). BDI-II changes were negatively correlated with changes in α2 (P < 0.01) and β1 (P < 0.05).
Conclusion
All intensities of single-session aerobic exercise can improve depressive symptoms in college students according to BDI-II scores. From the perspective of resting-state EEG frontal cortex lateralization, moderate and high-intensity exercise can improve depressive symptoms, with moderate intensity showing the most significant effect. The improvement in depressive symptoms is associated with increased frontal cortex synchronization.

Background Our primary focus was Schistosoma mansoni infection and schoolchildren. Within communities the social environment may promote individual risk of infection for the school-aged children. There will also be demographic groups who are not targeted or reached by preventive chemotherapy campaigns. The behaviours of these other groups will interact with those of school-aged children, resulting in further infection risk through exposure-related behaviours. Furthermore, perception of the disease may significantly influence the schoolchildren’s lived experience of the infection and associated disease. It is therefore crucial to document the daily experiences of schoolchildren living in schistosomiasis high transmission areas along Lake Albert, Hoima District.Methods An ethnographic study explored schoolchildren's perspectives and daily life organisations that shape their risk of schistosomiaisis and their perceptions of the disease. The study was conducted between November 2022 and August 2023. It involved in-depth interviews with schoolchildren and their parents, key informant interviews, focus group discussions with schoolchildren, and participant observations. Data was analysed using a reflexive thematic analysis. Code reports were generated inductively using ATLAS.ti (Version 7).Results The study revealed a significant level of knowledge and awareness about schistosomiasis among schoolchildren. They had understanding of the risk factors, continued exposure, and experiences of illness, though they had little autonomy to address these through their own behaviour as they were influenced by the behaviour of others and macro-factors such as WASH provision and economic need. Study participants experienced individual-level effects of schistosomiasis such as educational impacts and isolation as a significant form of stigma.Conclusions There is a need for continued community sensitisation and awareness campaigns to address social stigma, educational impact, and contamination and exposure-related behaviours. National and regional policies and programmes on WASH, livelihood and poverty eradication programmes need to be revisited in schistosomiasis high transmission areas to help provide alternatives and improve schoolchildren’s lived experiences.

Published: November 2024

Background. Implementation of problem-based learning has proven difficult in the majority of Arabic higher education institutions, including International Maaref University (IMU) due to deficiencies in the secondary education system. This study aimed to explore the effect of problem-based learning (PBL) practices on students’ satisfaction at IMU, Libya.
Methods. An online questionnaire was prepared and distributed to the third and fourth semester students of faculty of medicine at IMU.
Results. It was observed that the majority of students were satisfied with the PBL and declared that PBL had enhanced their problem-solving abilities, critical thinking, and develop social skills. However, the impact of PBL on social skills and leadership roles shows variability among students, reflecting diverse experiences.
Conclusions. These findings indicated that PBL effectively develops certain competencies; however, there is room for growth in fostering a comprehensive skill set among students.

Aim: This study examines the influence of visionary leadership on nurse interns' creativity and organizational effectiveness, with a particular focus on the mediating role of perceived organizational support.
Background: Leadership, particularly in healthcare care, significantly influences employee experiences and outcomes. Visionary leaders support their employees to gain organizational commitment and improve their creativity. However, the impact of visionary leaders on creativity among nurses and organizational effectiveness requires further exploration. Organizational support plays a crucial mediating role in the relationship between visionary leadership and nurses' creativity. When nurses perceive strong organizational support, they feel more valued and are more likely to engage in creative behaviors.
Subjects and Methods: A descriptive correlational design was conducted among nurse interns in Mansoura University Hospitals, Egypt. Four standardized questionnaires were used to examine perceptions of visionary leadership, organizational support, creativity among nurse interns, and organizational effectiveness perception; 464 nurse interns were polled. The study's hypothetical model was examined using AMOS structural equation modeling (SEM).
Results: Visionary leadership perception significantly affects nurse interns' creativity, organizational effectiveness, and perceived organizational support. As well, nurse interns' creativity significantly affects organizational effectiveness. Moreover, perceived organizational support mediates the relationship between visionary leadership as regards nurse interns' creativity and organizational effectiveness,
Conclusions: In sum, fostering a supportive environment and employing visionary leadership can empower nurse interns to be more creative, leading to enhanced problem-solving, improved processes, and better overall performance within healthcare organizations. This emphasizes the importance of leadership and support in driving innovation and effectiveness in healthcare settings.

Object recognition memory (ORM) allows animals to distinguish between novel and familiar items. When reactivated during recall in the presence of a novel object, a consolidated ORM can be destabilized and linked to that generated by the novel object through reconsolidation. The CA1 region of the dorsal hippocampus contributes to ORM destabilization and reconsolidation through mechanisms involving theta/gamma cross-frequency coupling (hPAC) and synaptic plasticity modulation. Ca2+/calmodulin-dependent protein kinase II (CaMKII) is vital for hippocampus-dependent memory processing and has been associated with theta activity-dependent plasticity in dorsal CA1. However, the specific role of hippocampal CaMKII in the lasting storage of reactivated ORM remains unclear, and its potential impact on memory-related oscillatory activity has not been previously investigated. To explore these questions, we employed a combination of behavioral, electrophysiological, and pharmacological approaches at various stages of ORM processing, and found that CaMKII is not necessary for ORM recall or reconsolidation but does regulate novelty-induced ORM destabilization by modulating hPAC.
