Published: January 2025

Teori perilaku dalam pendidikan diterapkan melalui program dengan prinsip-prinsip behaviorisme, seperti penguatan positif dan negatif. Misalnya, penghargaan atau pujian diberikan untuk perilaku yang diinginkan, sementara tugas yang tidak disukai siswa dihilangkan ketika mereka menunjukkan perilaku baik. Namun, teori perilaku sering dikritik karena terlalu fokus pada perilaku yang dapat diamati dan kurang memperhatikan proses mental internal seperti motivasi, pemahaman, dan kreativitas. Pergeseran terlihat dengan munculnya teori pembelajaran kognitif dan konstruktivis yang menekankan peran aktif siswa dalam membangun pengetahuan mereka. Tujuan penelitian ini untuk menganalisis teori perilaku dalam pembelajaran dengan metode systematic literature reviewe. Kesimpulan bahwa teori perilaku dalam pendidikan dan kesehatan mental semakin relevan di era komputer dan internet saat ini. Perubahan perilaku yang disebabkan oleh kemajuan teknologi informasi tidak didukung oleh fondasi kepribadian yang kuat, terutama dalam hal agama dan karakter. Degradasi moral dan masalah adaptasi sosial muncul sebagai hasilnya. Teori perilaku seperti kesadaran metakognitif sangat penting untuk membantu siswa belajar, terutama matematika. Siswa yang mampu berpikir secara metakognitif mungkin lebih percaya diri dalam menyelesaikan masalah. Selain itu, literasi digital memainkan peran penting dalam mengajarkan perilaku berpikir kritis dan kreatif sambil mempertahankan nilai-nilai sosial, emosional, dan spiritual. Di era metaverse, teknologi seperti augmented reality dan virtual reality meningkat dalam pengajaran

The Implementation of transformational Leadership and Teacher Work Engagement on Increasing Number of Students
Authors: Manueke Jessica Mellyta Lidya , Tung Khoe Yao
Published: January 2025

The purpose of this study is to identify and describe the implementation of the roles of principals and teachers in increasing the number of school students in the coming year. Additionally, it aims to provide suggestions and ideas to schools, principals, and teachers on maximizing school promotion to increase the number of elementary school students. This research uses a qualitative study involving 11 participants at School House. Data triangulation was analyzed using coding (Strauss, 1990). The principal has implemented a transformational leadership style effectively in developing the school but has not been consistent due to limited infrastructure and resources, including facilities and teachers. This inconsistency is partly because teacher work engagement has not been the principal's main focus in efforts to increase the number of students at SD School House. The results of the study show that the increase in the number of students in the school is due to the implementation of transformational leadership in school operations.
Rural students' pathways to higher tertiary education in Zimbabwe: Overcoming barriers, promoting inclusion and success
Authors: Chidakwa Nowell
Published: January 2025

Accessing higher tertiary education for rural students in Zimbabwe is a complex journey shaped by various socio-economic, cultural, and geographic factors unique to their circumstances. This study examines the experiences of rural students in accessing, participating in, and attaining higher tertiary education through the lens of Freire's theory of critical consciousness. It employs a critical emancipatory research paradigm, utilising participatory action research methodologies. Twenty participants were purposively selected and actively involved as co-researchers throughout the research process to identify empowering practices that can transform their educational realities. Data was collected using focus group discussions and Photovoice, allowing participants to share narratives and visually represent the barriers in their educational journeys. Critical discourse analysis revealed various factors that shape educational trajectories, such as geographic isolation, financial constraints, a lack of collegiate guidance, and the internalisation of negative perceptions about rural identities. Findings also highlighted protective factors, including strong family and community support systems, self-determined mindsets, and engagement with college-bridging programmes. Through critical dialogues, participants explored ways to challenge internalised stigmas and develop critical literacies to navigate systemic barriers. The PAR process enhanced participants' critical consciousness and enabled them to collectively generate rural student-led solutions for equitable educational access. The importance of adopting strengths-based and culturally sustaining approaches that amplify the voices of rural students in transforming policies and practices was highlighted. Importantly, this study demonstrated the emancipatory potential of PAR in fostering resilience and self-advocacy among rural students, thereby promoting higher tertiary education as a means for social and economic mobility.

Published: January 2025

The primary aim of this paper is to assess the effectiveness of a low-cost stereo (depth) camera as a non-destructive tool for the detection and measurement of cracks in concrete surfaces. The experiment was carried out on four concrete beams with cracks, created with different concrete mixes. The mixes of the four beams were made up of lightweight aggregates with 12% of normal weight aggregates. One beam was used as a reference without fibers, while 3D steel fiber reinforcement, 5D steel fibers reinforcement, and a hybrid fibers mix of 5D steel fiber and synthetic were used for the other three beams. The cracks in the beams were measured manually followed by taking their stereo images with a ZED camera. The ZED images were processed to produce 3D models of the concrete surfaces, which are useful for crack measurement in a three-dimensional framework. The project results are particularly significant in the measurement of all three dimensions (length, width and depth), with less than a 10% error between the actual and the experimental procedure. Relatively, multiple differential approaches gave a less accurate result of a 15% error mainly due to syntax errors. Results suggest that the ZED depth camera is an effective tool for robust detection and measurement of cracks in concrete surfaces.

, 48 EBs are detected and two are newly discovered. This specific field has been observed 52 times by the LAMOST Medium-Resolution Survey DR 9, which facilitates a comprehensive analysis of the EBs. For EBs with LAMOST medium-resolution spectra, radial velocity curves were obtained, and their precise orbital parameters were determined by simultaneously analyzing photometric light curves and radial velocity curves. For the other EBs with only photometric light curves, we used the q-search or the temperature ratio method to determine their initial mass ratios and then determined the orbital parameters. It is found that 15 EBs belong to detached systems, one to semi-detached systems, and 32 to contact systems. Based on the O − C analysis for 26 EBs with sufficient eclipsing times, we found a long-term decrease in the orbital period of 11 EBs and a continuous increase of five EBs, which are due to the material transfer between the two components. The O − C curve of 1 EB shows a distinct periodic variation, which is caused by the light travel time effect, and the third body is likely to be a black hole. By applying the spectral subtraction method to 13 EBs with LAMOST medium-resolution spectra, 10 systems exhibit distinct Hα emission lines, in which one system exhibits double-peaked lines near phases 0.25 and 0.75, implying strong chromospheric activity. In the massluminosities and mass–radius distributions, most of the more massive components are less evolved than the less massive ones.
Observational Study of Recurrent Jets: Evolution of Magnetic Flux, Current, and Helicity
Authors: Zhou Chang , Guo Yang , Chen Guoyin , Qiu Ye , Ding M.D.
Published: January 2025

We observed three recurrent blowout jets in an active region with the Atmospheric Imaging Assembly (AIA) aboard the Solar Dynamics Observatory. Using Helioseismic Magnetic Imager data we found that the magnetic flux of an emerging negative pole increases steadily before declining just as the jets erupt. Certain physical quantities, such as the total unsigned vertical current, align with the periodicity of the jets. The differential affine velocity of vector magnetograms reveals strong shear around the negative pole. The Doppler velocity map, calculated from the Hα spectra observed by the Chinese Hα Solar Explorer, shows upflows with large initial velocity before they can be observed by AIA. The magnetic field derived from the nonlinear force-free field (NLFFF) model suggests a topology akin to a fan–spine structure, consistent with AIA images. We calculated the evolution of the volumetric helicity ratio using the NLFFF model and found its phase aligns with the jet flux in AIA 171 Å. These results suggest that recurrent jets may be triggered by the accumulation and release of energy and helicity, driven by emergence, shearing, and cancellation of photospheric magnetic field.

++ Modeling in the Martian Dayside Ionosphere: Insights from Natural Lifetime Analysis
Authors: Cheng Long , Vigren Erik , Persson Moa , Gu Hao , Cui Jun
Published: January 2025

The molecular dication CO2
++ has, as previously reported, been detected in the Martian ionosphere by the Neutral Gas and Ion Mass Spectrometer on the Mars Atmosphere and Volatile Evolution (MAVEN) mission. Photochemical models have also been developed to reproduce the CO2
++ density in the Martian dayside ionosphere but underestimate significantly the observations. In this study, we examine the influence of the CO2
++ natural lifetime against spontaneous dissociation on its modeled density. We show that extending the assumed CO2
++ lifetime significantly reduces the discrepancy between the photochemical model predictions and MAVEN observations. Specifically, when treating CO2
++ as stable against natural dissociation, instead of invoking a lifetime of 4 s as done in previous studies, the data-to-model ratio comes close to unity throughout the altitude range 160–220 km. We argue that stability of CO2
++ against natural dissociation does not necessarily conflict with results from a frequently cited experimental investigation. Our study provides new insights for advancing photochemical modeling of the Martian ionosphere and underscores the need for further laboratory measurements targeting fundamental properties of doubly charged ions.

Published: January 2025

Introduction: Post-COVID-19 syndrome refers to the occurrence of symptoms lasting more than 4 weeks in individuals who have recovered from COVID-19. This study aims to investigate the post-COVID-19 symptoms in healthcare professionals.
Methodology: This descriptive study included 166 healthcare professionals who had tested positive for COVID-19 via PCR at least four weeks prior and subsequently presented to the Family Medicine Clinic at Pamukkale University Training and Research Hospital. Participants` demographic data, medical history, COVID-19 history and ongoing or newly emerged complaints and symptoms were evaluated, and physical examinations were carried out and recorded on a patient information form. Blood tests were conducted, and the results were analyzed.
Results: The most common post-COVID-19 symptoms and complaints observed in our study were difficulty in performing daily activities (32.5%; n = 54), fatigue (26.5%; n = 44), forgetfulness (25.9%; n = 43) and weakness (24.1%; n = 40), respectively. Smoking, alcohol use, hospitalization, the need for oxygen support and having comorbidities such as asthma, diabetes, hypertension and rheumatism were found to be associated with various post-acute symptoms. Post-acute symptoms were most frequently observed in individuals vaccinated with Sinovac (38.5%), followed by those who were unvaccinated (35.7%). Least symptoms were seen in individuals vaccinated with only Biontech (15.4%).
Conclusions: The most common post-COVID-19 symptoms observed in our study were difficulty in performing daily activities, fatigue, forgetfulness and weakness. Having comorbidities was found to be associated with various post-COVID-19 symptoms.

Authors: Fu Linlin , Yao Huimin , Xu Wei , Li Li , Wang Baoyan
Published: January 2025

Introduction: The combination of antibiotics and warfarin is used frequently in clinical practice. However, the impact of this combination on the anticoagulant efficacy of warfarin remains uncertain, posing challenges to clinical decision-making. This study aimed to evaluate the influence of various antibiotics on the international normalized ratio (INR) values in hospitalized patients who were concurrently administered warfarin.
Methodology: This retrospective cohort study enrolled patients who received concomitant warfarin and antibiotic therapy at the Nanjing Drum Tower Hospital, between January 2013 and December 2022. The patients were categorized into 8 groups based on the type of antibiotics they were received. The demographic characteristics were recorded, and the clinical outcomes were focused on changes in INR values after combining antibiotics in warfarin users.
Results: A total of 623 patients were enrolled in this study. Based on analysis of covariance (ANCOVA), the maximum INR values of the combinations were as follows: 2.72 for oxazolidinones, 2.86 for β-lactams, 2.86 for carbapenems, 2.91 for glycopeptides, 2.91 for macrolides, 3.77 for quinolones, 4.13 for sulfonamides, and 4.37 for antifungal agents. Pairwise comparisons revealed that quinolones, sulfonamides, and antifungal agents manifested the most substantial elevation in INR values when co-administered with warfarin. β-lactams, glycopeptides, oxazolidinones, macrolides, and carbapenems demonstrated a comparatively weaker impact on INR values.
Conclusions: Co-administration of warfarin with antibiotics led to an elevation in INR values in patients. Quinolones, sulfonamides, and antifungal agents had the most pronounced impact.
Effects of archipelago geo-environmental dynamics on phylogenetic tree shape
Authors: Vidal-Hosteng Amandine , Thébaud Christophe , Etienne Rampal S. , Aguilée Robin
Published: January 2025

In archipelagic environments, the successive emergence and submergence of islands induces variations of area, spatial structure and isolation. Here, we aim to understand how such geo-environmental dynamics, by inducing variations in migration, speciation and extinction over time, may impact phylogenetic patterns. We use a neutral, stochastic, individual-based model which simulates a community evolving in an archipelago where four islands emerge and submerge consecutively. We record each birth, death and migration event, allowing us to build the complete phylogeny at any time, from which we extract the phylogeny of extant species. We show that the rate of lineage accumulation and tree imbalance vary according to a hump-shaped curve, and we show that this is mainly due to variations in area and inter-island connectivity. We highlight that past abrupt changes, such as island emergence, may leave persistent imprints in the rate of lineage accumulation. We show that the spatial configuration of an archipelago modulates these effects: (i) enhancing inter-island connectivity results in more frequent inter-island speciation events, thus a faster accumulation of lineages, and in larger evolutionary radiations, thus highly imbalanced phylogenies ; (ii) increase in mainland connectivity brings ancestral lineages to the islands which slows down the rate of lineage accumulation and increases the species turnover allowing for more balanced phylogenies. Taking into account variations in the geo-environmental configuration of an archipelago is important to understand the shape of contemporary phylogenies. However, these effects have to be interpreted in the context of the spatial configuration of an archipelago.

Approximate Counting for Spin Systems in Sub-Quadratic Time
Authors: Anand Konrad , Feng Weiming , Freifeld Graham , Guo Heng , Wang Jiaheng
Published: January 2025

We present two randomised approximate counting algorithms with $\widetilde{O}(n^{2-c}/\varepsilon^2)$ running time for some constant $c>0$ and accuracy $\varepsilon$: (1) for the hard-core model with fugacity $\lambda$ on graphs with maximum degree $\Delta$ when $\lambda=O(\Delta^{-1.5-c_1})$ where $c_1=c/(2-2c)$; (2) for spin systems with strong spatial mixing (SSM) on planar graphs with quadratic growth, such as $\mathbb{Z}^2$. For the hard-core model, Weitz's algorithm (STOC, 2006) achieves sub-quadratic running time when correlation decays faster than the neighbourhood growth, namely when $\lambda = o(\Delta^{-2})$. Our first algorithm does not require this property and extends the range where sub-quadratic algorithms exist. Our second algorithm appears to be the first to achieve sub-quadratic running time up to the SSM threshold, albeit on a restricted family of graphs. It also extends to (not necessarily planar) graphs with polynomial growth, such as $\mathbb{Z}^d$, but with a running time of the form $\widetilde{O}\left(n^2\varepsilon^{-2}/2^{c(\log n)^{1/d}}\right)$ where $d$ is the exponent of the polynomial growth and $c>0$ is some constant.

Exploring the Nexus Between Urban Land Use/Land Cover (LULC) Changes and Urban Growth Analysis Using Geoinformatics in Tumkur City, India
Authors: Kumar A. Kishor , . Govindaraju , Rakesh C. J. , Lokanath S.
Published: January 2025

For the past several decades, Tumkur has been one of the fastest-developing cities in Karnataka. Hence, an assessment concerning the identification of LULC mutations and their intensity and urban sprawl in Tumkur City has been employed using cutting-edge Geospatial techniques. In this study, multi-temporal satellite imagery such as Landsat 5 (2000), Resourcesat-1 (2005, 2009 & 2012), and Sentinel-2A (2015 & 2020) were utilized to monitor historical LULC changes, land transformation, direction of urban growth and sprawl. The outcome of the change detection demonstrates that between 2000 and 2020, the built-up area expanded significantly, from 24.94 km2 to 60.59 km2. Consequently, the land transformation matrix analysis shows that substantial modifications in LULC have occurred over the period, with a rise in built-up areas and plantations and a decline in agricultural land, water bodies, and scrubland. Further, urban expansion analysis using UEII (Urban Expansion Intensity Index) revealed that most of the area is in the fast-paced stage of urban expansion. Moreover, two well-known indices; the Annual Urban Spatial Expansion Index (AUSEI) and the Annual Built-up Change Index (ABCI), show a significant positive correlation between them (R2 = 0.69) justifying the increased urban growth in the study area. Whereas, built-up density and the Annual Urban Spatial Expansion Index (AUSEI) show a negative correlation (R2 = 0.55) indicating the presence of compactness of the core of the city. Apart from the above analysis, urban sprawl was effectively interpreted using zones formed using Shannon entropy; NNE, ESE, and SSW have high urban sprawl due to National Highways, growth of Industries, and infrastructure activities developed by the government. Further, the present study’s findings will contribute to understanding land use dynamics, urban sprawl, urban growth analysis, and future projections, as well as provide crucial information for decision-making and urban planning processes, to the urban planner to support acceptable land use management and guiding plan for appropriate growth of urban areas.

Morphological Study of Nutrient Foramen of Left Human Clavicle in Male and Female
Authors: Islam Nazia Binte
Published: January 2025

Background: The clavicle demonstrates significant morphological variations between males and females, making it valuable for sex determination in forensic investigations. The nutrient foramen’s location and characteristics are crucial for surgical procedures, yet comprehensive morphometric data specific to certain populations remains limited.

Objectives: This study aimed to analyze the morphological variations in left clavicles, focusing on sexual dimorphism and nutrient foramen characteristics, to establish population-specific morphometric standards and enhance surgical and forensic applications.

Methods: A cross-sectional analytical study was conducted on 120 dry ossified left human clavicles (70 male, 50 female) using standardized measurement techniques. Measurements included basic morphometric parameters, angular measurements, curvature characteristics and nutrient foramen features. Data were analyzed using Student’s t-test, with statistical significance set at p≤0.05.

Results: Significant sexual dimorphism was observed in most parameters. Male clavicles showed greater mean length (136.83 ± 6.79 mm vs 128.36 ± 4.43 mm), midclavicular circumference (36.80 ± 1.60 mm vs 34.35 ± 1.89 mm) and weight (16.45 ± 2.76 g vs 12.86 ± 1.94 g) compared to females (p<0.001). Single nutrient foramina predominated in both sexes (92.86% males, 86% females), typically located on the posterior surface (90% males, 88% females) in the middle third of the clavicle (93% males, 92% females). While most parameters showed significant sexual differences, the robustness index and some articular surface measurements demonstrated no significant variation between sexes.

Conclusion: This study establishes comprehensive morphometric standards for the studied population, demonstrating significant sexual dimorphism in most parameters and consistent patterns in nutrient foramen characteristics. These findings provide valuable reference data for surgical procedures, forensic investigations and anthropological studies, while highlighting the importance of population-specific morphometric standards.
Role of TSH in Predicting Malignant Thyroid Tumours
Authors: Z Sajina
Published: January 2025

Background: Thyroid cancer,the most prevalent endocrine cancer is rising in number.Thyroid cancer can manifest mainly as dominant nodule or as a solitary nodule in a MNG. Researchers have observed thyroid nodules in 4-7% of the general population.Its very difficult to differentiate between benign and malignant thyroid swellings. There are several reliable indicators to identify thyroid nodules which are malignant. Recently, some studies have proposed a link between elevated Thyroid stimulating hormone levels, even within the normal range and the later identification of malignancy.

Aims and objective: to determine the predictive role of serm TSH in thyroid malignancies and to examine the association between serum TSH concentration and thyroid cancer.

Material and Methods: We included a total of 30 thyroid cancer cases in a retrospective investigation. We assessed serum TSH levels, pathology, age and sex. We analyzed the association between malignant thyroid tumours and serum TSH levels.

Result: The majority of thyroid malinancy patients in our study (16 out of 30) had serum TSH values which falls within the normal range but on the higher side.

Conclusion: Patients with higher serum TSH concentrations have an increased incidence of thyroid cancer which is attributed to the tropic impact of TSH on thyroid tissue, which promotes neoplasia and carcinogenesis. For patients with thyroid malignancies, the baseline blood TSH level can serve as a biochemical predictor of thyroid cancer. Upon diagnosis of thyroid cancer, a high serum TSH level could suggest a more aggressive and advanced stage of the disease. The terms thyroid gland, Thyroid-Stimulating Hormone (TSH) and cancer are pointing to a same direction.

Information and Communication Technology has become essential in our daily life. ICT provides great benefits in education as it enables interactive learning. The world has changed, and ICT brings a new way to conceive teaching and learning, providing access to online educational systems services. It is an innovative and creative way to help the educational area. When technology is integrated into class, the teaching and learning process become more accessible and dynamic. Part of the drive towards greater use of technology in education is aimed at modernizing schools and equipping the pupils of today with skills that will make them able to use such technology in the workplace once they leave school. Other stated goals have been to reduce teacher workload by making planning and resources available over the internet or to reduce bureaucracy by providing and exchanging information in electronic form. Perhaps the goal in promoting the use of ICT in schools has been to increase the effectiveness of teaching and improve pupils’ learning.  In this paper, a study regarding the use of ICT in education was made.

Since 2017, research has been conducted into the effects of (mono-)silicic acid (product: AB SiliFish®) on fish and shrimp.
The aim of the present study is to investigate the effects of stabilized silicic (sSA) on the growth, yield and survival of four fish species: Rohu, Catla, Tilapia
and Pangasius in 0.5 ha freshwater ponds for 240 to 360 days.
In addition, two forms of applications and two dosages were investigated: a. application of silicic acid to the pondwater and b. mixing the product with
fish feed using two dosages.
Water quality was monitored using physico-chemical analyses and the effects on other aquatic organisms, such as phytoplankton and zooplankton, were
analysed.
The results showed that growth, survival, feed utilisation and yield of all four fish species increased significantly with both application types, while mixing
the product with fish feed at a dosage of 2 ml/kg was higher compared to application in pond water.
Physicochemical parameters were also improved, while plankton abundance increased significantly.
It is concluded that SATA (Silicic Acid Technology for Aquaculture) significantly increased yields of many fish species compared to controls, as well as
water quality.
SATA has no negative effects on fish or water quality and is an environmentally friendly technology that reduces the carbon footprint.
