Disappearance of vernacular character in rural residences: An assessment of residents’ requirements for rural residential façades and environments in Suzhou, Jiangsu, China
Authors: Yao Sucheng , Budthimedhee Kanjanee
Published: January 2025

This study, framed within the context of the Harmonious and Beautiful Countryside policy, focuses on optimizing the living environment of rural housing by addressing the loss of diverse heritage in rural architecture and landscapes. Through fieldwork and importance-performance analysis methods, the research investigates the façades and environments of rural houses in Suzhou, Jiangsu, China. By incorporating the “vernacular” evaluation factors identified in previous studies, this study adopts a user-centered perspective to provide practical insights into rural cultural landscapes, thereby augmenting existing literature. The study reconstructs elements of rural residences and their environments to enhance residents’ comprehension and yield more objective evaluation outcomes. Analysis reveals that both native and non-native residents share similar views on the importance and performance of various factors. Environmental quality and building functionality emerge as top priorities for residents, while Suzhou’s efforts to preserve traditional architectural esthetics are notably effective. However, field observations also highlight urbanization’s impact on rural housing, such as the use of non-native materials that compromise traditional rural architectural styles. To tackle these challenges, this study proposes the following strategies for rural regeneration: (i) permit integration of new materials, technologies, and spatial configurations with traditional rural architecture; (ii) incorporate historical context, cultural continuity, traditional materials, and lifestyle needs into building renovations; and (iii) establish a dynamic regulatory mechanism for rural residential architecture to aid residents in optimizing their buildings and surroundings. These strategies aim to mitigate the effects of excessive urbanization and provide a user-centered approach for future research on rural cultural landscapes.
Machine Learning in Cybersecurity: Proactive Threat Detection and Response
Authors: - Sai Krishna Adabala
Published: January 2025

The rise in the complexity and number of cyber threats calls for sophisticated solutions surpassing conventional post-incident strategies. Machine learning (ML) has emerged as a transformative tool in cybersecurity, enabling organizations to recognize, predict, and mitigate potential threats effectively. This article examines how various ML algorithms enhance cybersecurity practices through real-time anomaly detection, virus identification, and the recognition of abnormal user behavior, thereby significantly bolstering threat management capabilities. We highlight several real-world use cases that demonstrate the successful application of ML in improving threat detection and response times across different sectors. However, the integration of ML in cybersecurity is accompanied by challenges, including data leakage, adversarial attacks, and the need for high-quality labeled datasets, which can hinder its effectiveness. Furthermore, we discuss prospects in this rapidly evolving field, such as the development of explainable artificial intelligence (XAI) and federated learning, which promise to enhance transparency and foster collaboration among security teams. Ultimately, this article argues that ML-based solutions provide proactive strategies for confronting contemporary threats and empower organizations to shift from reactive to anticipatory defense mechanisms. This enables them to neutralize potential vulnerabilities before they can be exploited.

Published: January 2025

This research focuses on the legal protection for honorary teachers whose rights are not fulfilled in private schools. Honorary teachers, often employed on a non-permanent basis, are vulnerable to not receiving their entitled rights, such as salaries, social security, and other benefits. Despite their significant role in the education system, particularly in private institutions, the lack of legal protection often leads to exploitation and adverse working conditions.
The aim of this study is to examine the legal framework governing the rights of honorary teachers in Indonesia, with a specific focus on private schools. It explores the extent to which these teachers are protected under Indonesian labor laws and educational regulations, particularly the Education Law and the Labor Law. This study also investigates the challenges honorary teachers face in asserting their rights and the mechanisms available for them to seek redress.
Using a qualitative approach, the research analyzes case studies, legal documents, and interviews with both teachers and school administrators to understand the situation. The findings highlight gaps in the enforcement of legal protections, with many teachers unaware of their rights or too vulnerable to challenge non-compliance.
This study concludes that honorary teachers in private schools require stronger legal protections to ensure their rights are fulfilled. Recommendations include improved awareness programs for both teachers and administrators, the strengthening of legal frameworks, and better enforcement mechanisms to prevent the exploitation of these educators. Legal reform and policy adjustments are necessary to provide honorary teachers with adequate protection, promoting fair and just working conditions in the education sector.

Neutron Capture Therapy (NCT) — highly selective method of binary radiotherapy of malignancies, which is based on physical phenomenon of thermal neutron radiation capture by atoms’ nuclei. Currently only 10B mediated NCT, known as boron neutron capture therapy (BNCT), is used in clinical practice. Boronophenylalanine — a modified amino acid is most widely used as 10B carrier. Despite of more than 70-years history of BCNT clinical application and promising results of curing patients with different tumors, this method of treatment is still under research and development. The most urgent issue is studying and prediction of radiation effects of healthy and tumor tissues after BNCT application. This task can be solved in experiments involving animals. The review contains results of BNCT studies both in laboratory animals with different tumor models and veterinary practice. Induced and transplanted models of central nervous system, oral cavity as well as subcutaneous and metastatic models are considered in the review. Obtained results of the studies show possible high antitumor efficacy of BPA mediated BNCT and fundamentally different mechanisms of BNCT effect on tumor and healthy tissues comparing to other known types of radiotherapy. Many issues still require addition research with modern methods of studies, such as in vivo preclinical imaging.

Study on the Improvement of Regulatory Systems and Policy Convergence for Genome-Edited Products: A Policy Approach to Harmonization of International Standards
Authors:   Taegu Science University Defense Security Institute, Kim Mi Sook
Published: January 2025

This study examines the policy approach to improve the regulatory system of Korea for genetically edited organisms and foods using new technologies and to harmonize international standards. To this end, the policy approach was discussed focusing on the regulatory measures of GMOs based on the regulatory systems of major countries and the policy convergence theory. The analysis results showed that there could be significant differences when applying ex post facto regulations such as GMO labeling, traceability, crop registration, and license renewal. In particular, the regulatory system for genetically modified foods and foods using new technologies is inadequate due to intermittent food safety accidents in the food safety regulatory science field in Korea. In addition, it was confirmed that domestic regulations are not consistent with international standards and are facing problems such as trade barriers. As a result, important policy implications were derived for improving the regulatory system of Korea for genetically edited organisms and foods using new technologies, including restoring and increasing consumer trust, reorganizing the regulatory system and ensuring consistency with international standards, fostering experts in the field of regulatory science, and strengthening research capacity.

This study analyzed the effects of a 15-week exercise program on Kookmin Physical Fitness 100 (KPF100) test results, focusing on pre- and post-changes. The participants consisted of 30 students enrolled in the Department of Noncommissioned Officer (NCO) Studies at P University, located in Gyeongbuk. They were divided into an experimental group (15 students: 11 males, 4 females) and a control group (15 students: 9 males, 6 females). A T-test was conducted for the analysis. First, the indicators of physical composition, such as height and weight, showed no statistically significant differences between pre- and post-measurements in both the experimental and control groups (p > .05). Second, in the experimental group, both left-hand and right-hand grip strength (muscular strength) showed significant improvements between pre- and post-measurements (p < .001). Third, sit-and-reach (flexibility) significantly improved in the experimental group (p < .01). Fourth, cross sit-ups (muscular endurance) showed significant improvements in the experimental group (p < .01). Fifth, the number of shuttle runs and VO2Max (cardiopulmonary endurance) significantly improved in the experimental group (p < .01). Sixth, the 10m 4-round shuttle run (agility) showed significant improvements in the experimental group (p < .05). Finally, the standing long jump (explosive power) demonstrated statistically significant differences in the post-measurements between the experimental and control groups (p < .05), but neither group showed significant pre- to post-changes. Overall, the KPF100 results revealed significant improvements across all eight fitness indicators in the experimental group, while no significant changes were observed in the control group. These findings confirm that the 15-week exercise program had a positive impact on the participants' physical fitness.

Authors:   Taegu Science University Defense Security Institute, Oh Seo Hyeon , Han Seong Min , Kim Mi Jung
Published: January 2025

This study analyzed the impact of social stigma on the resilience of out-of-school youth and examined whether self-esteem, family support, and prosocial characteristics of peer groups have moderating effects. A survey was conducted with 320 out-of-school youth from youth support centers in Gyeongsangbuk-do, Daegu, Gangwon-do, Jeollanam-do, and Seoul, targeting those aged 9 to 24. After excluding invalid responses, data from 300 participants were analyzed using SPSS 25.0 and SPSS Process Macro. The results revealed a negative relationship between social stigma and resilience, indicating that higher levels of social stigma correlate with lower resilience. Self-esteem, family support, and prosocial peer group characteristics showed significant moderating effects in mitigating the negative impact of social stigma, while friend support and adult support did not exhibit meaningful moderating effects. Based on these findings, the study highlights the need for interventions that strengthen self-esteem, family support, and peer group connections among out-of-school youth, along with policies to reduce social stigma.

Multifractal Analysis on Ozone Depletion and Climate Change: The Time Series Approaches
Authors: M. Meenakshi  , A. Gowrisankar
Published: January 2025

The ozone layer has acted as the planet’s natural sunscreen, protecting people, plants, and animals from harmful ultraviolet rays. The Antarctic ozone hole was first announced in a paper by the British Antarctic Survey’s Joe Farman, Brian Gardiner, and Jonathan Shanklin in 1985. Many investigations are still conducting to determine the connection between ozone depletion and climate change. This research study investigates the impact of the ozone layer’s depletion at the Antarctic pole on global climate change data such as temperature and precipitation, after the year 1985 through a fractal dimension, Multifractal Detrended Fluctuation Analysis (MFDFA), and standard correlation coefficient. For this, the research work has analyzed 45 years of climate change variables such as global monthly temperature anomaly, global monthly precipitation anomaly, and Southern Hemisphere minimum ozone time series data from 1979 to 2023. The fractal dimension of the time series is obtained by rescaled range analysis, which is used to identify the fractality of the time series and long-range correlations and persistence. To study the multifractality of these fractal time series, MFDFA procedure has been applied. By applying MFDFA to these time series data, this research has identified significant multifractal characteristics, indicating complex dynamics and long-range correlations, and identified potential nonlinear patterns. This research provides valuable insights into the complex dynamics of time series data, as revealed by the calculated exponent values and MFDFA spectrum. The strong correlation observed between the exponent values of temperature anomalies, and precipitation anomalies, with ozone depletion time series provides compelling evidence for the significant impact of ozone depletion on climate change. These results highlight the potential of multifractality for understanding the intricate mechanisms underlying climate change.

Authors: Achulu Mercy , Ndungu Perpetual , Kamau Luna , Gichuki Paul M
Published: January 2025

Background: Physical integrity and insecticidal efficacy of long-lasting insecticide-treated nets (LLINs) is influenced by the handling practices during use. This was an evaluation of Yorkool® pyrethroid-based LLINs after 12 months of use to determine the washing and drying practices, physical conditions and bio-efficacy. Methods: This was a cross-sectional household survey in an area where rectangular Yorkool® a pyrethroid LLINs were distributed during national mass net distribution campaign in 2021. Questionnaires were used for data collection and bioassay tests were done from thirty randomly selected nets.  Results:  262 household heads were interviewed with their mean age being 46.9 years (SD 17.4 years) and level of education was mainly primary (70.2%). Most households (71.8%) had 1 to 2 sleeping spaces. The households had a total 468 LLINs with 95.1% having been washed at least once. About three-quarters (74.4%) of the LLINs had been washed using local bar soap, with 99.6 % having not been scrubbed on hard surface during washing and 72.1% were dried under a shade. Those evaluated for physical integrity and had at least one hole made up 77.8% of the nets and 57.2% were too torn and requiring replacement. Bio-efficacy test recorded a mean KD of 92% after 1 hour, and mean mortality of 86% after 24 hours. The nets that passed the WHO efficacy cut off for mortality (≥80%) after 24 hours were 83.3% and 70% passed the KD (≥95%) cut off after 1 hour. Conclusions: While more than a half of the Yorkool® LLINs needed replacement due to poor physical integrity after one year of use in the households, the bio-efficacy of the LLINs was relatively high with the mortality on vectors meeting the WHO threshold

Published: January 2025

Cardiovascular diseases, particularly ischemic heart disease (IHD), are the leading cause of mortality globally, accounting for 16% of deaths. Effective management of ischemic cardiomyopathy (ICM) is crucial, as outlined in the latest European Society of Cardiology (ESC) guidelines for chronic coronary syndrome (CCS). The guidelines emphasize a structured approach comprising four key steps: a general clinical evaluation to exclude non-cardiac causes, cardiac examination, and likelihood estimation using echocardiography, diagnostic testing such as stress echocardiography and coronary CT angiography, and treatment involving lifestyle changes and medication, alongside potential revascularization. The review underscores the importance of coronary angiography and functional assessments in diagnosing ischemic heart failure (IHF) and guiding treatment strategies. Non-invasive imaging techniques, including stress echocardiography and myocardial perfusion scintigraphy, are valuable for assessing ischemia and myocardial viability while reducing unnecessary invasive procedures. Coronary CT angiography is also examined for its procedural advantages and risks. A comparative analysis of diagnostic modalities highlights the strengths and limitations of each technique, emphasizing the need for individualized approaches based on patient characteristics. The ESC 2024 guidelines advocate for a patient-centered imaging strategy based on the likelihood of coronary artery disease (CAD) while addressing the economic and environmental impacts of imaging practices. Overall, implementing these guidelines and leveraging diverse imaging modalities can optimize management strategies for IHD, ultimately improving patient outcomes.

Published: January 2025

Nowadays, Manufacturing and automotive industries have begun to employ renewable resources as a result of public awareness and rigorous legal requirements relating to the usage of polymers. This study has focused on employing Snake Grass (SG) fiber as reinforcement in Aegle Marmelos with Epoxy blended hybrid matrix (AME), since natural fiber reinforced composites provide a significant role in the development of lightweight structural components. The primary study investigated the effects of fibre length and fibre volume percentage on the mechanical properties of snake grass fibre. Based on the test results, the composite with a 15 mm fibre length and a volume percentage of 20% SG fiber has better mechanical qualities. Finally, mechanical and dynamic mechanical properties are used to assess the impact of Aegle marmelos with Epoxy blended hybrid matrix addition into the snake grass fibre composite. The inclusion of natural fiber with epoxy matrix and natural (Aegle marmelos) filler increased composite characteristics due to their synergistic effect. This enhances the adhesion and stress transmission uniformity between the reinforcements. The morphology of the fiber surface is assessed using micrographs acquired with a scanning electron microscope.

Published: January 2025

This study explores the potential development of an agricultural communications program at the [Institution]. It aims to understand the current knowledge of and interest in the discipline among Ontarian agriculture students and industry professionals, and the perceived importance and employability of hypothetical program graduates, contributing to the Sustainable Development Goal of quality education. Using a qualitative descriptive case study approach, focus groups with 18 students and six industry professionals were conducted. Data were collected through open-ended questions, analyzed using open coding and thematic analysis, and triangulated with demographic surveys. The findings reveal a general lack of understanding of agricultural communications among Ontarian students, who nonetheless recognize the field's potential to bridge gaps between producers and consumers, particularly through social media and diverse job opportunities. Industry professionals emphasized the growing importance of storytelling, crisis communication, and the need for poly-skilled graduates capable of addressing varied communication needs within the agricultural sector. Both stakeholder groups expressed interest in an agricultural communications academic program. Recommendations include engaging broader industry support for the program, integrating agricultural communications training across existing agricultural disciplines at the [Institution], and continuing research to refine curriculum development.
Precursor sticking coefficient determination from indented deposits fabricated by electron beam induced deposition
Authors: Kuprava Alexander , Huth Michael
Published: January 2025

A fast simulation approach for focused electron beam induced deposition (FEBID) numerically solves the diffusion–reaction equation (continuum model) of the precursor surface on the growing nanostructure in conjunction with a Monte Carlo simulation for electron transport in the growing deposit. An important requirement in this regard is to have access to a methodology that can be used to systematically determine the values for the set of precursor parameters needed for this model. In this work we introduce such a method to derive the precursor sticking coefficient as one member of the precursor parameter set. The method is based on the analysis of the different growth regimes in FEBID, in particular the diffusion-enhanced growth regime in the center region of an intentionally defocused electron beam. We employ the method to determine the precursor sticking coefficient for bis(benzene)chromium, Cr(C6H6)2, and trimethyl(methylcyclopentadienyl)platinum(IV), Me3CpPtMe, and find a value of about 10−2 for both precursors, which is substantially smaller than the sticking coefficients previously assumed for Me3CpPtMe (1.0). Furthermore, depositions performed at different substrate temperatures indicate a temperature dependence of the sticking coefficient.

Published: January 2025

Osteoporosis management in post-menopausal women focuses on fracture prevention, with denosumab as a key therapeutic option. Despite its proven efficacy in reducing fracture risk and increasing bone mineral density (BMD) over 10 years, its long-term impact remains uncertain. We evaluated the literature on its efficacy and safety beyond the initial decade. Clinical trials and real-world studies confirm denosumab’s sustained efficacy, especially in lumbar spine BMD, with hip BMD stabilizing. Concerns about adverse events (AEs) like hypocalcemia and osteonecrosis of the jaw necessitate vigilant monitoring. Risks of atypical femoral fractures and malignancies also require attention, despite unclear links to treatment duration. Clinical guidelines for denosumab beyond 10 years are limited, emphasizing the need for careful monitoring. In certain scenarios, such as advanced chronic kidney disease, prolonged denosumab may be required to balance AE risks with fracture prevention benefits. Denosumab shows potential for long-term efficacy in augmenting BMD; however, monitoring for AEs is crucial to guide clinical decision-making effectively.

The Customer Order Scheduling (COS) problem involves organizing a set of orders, each characterized by a release time, a due date, and a processing time, with the objective of minimizing the costs associated with delivery delays. This study introduces an innovative approach, the Streamline COS, which integrates order scheduling optimization with improved resource utilization and a reduction in production inefficiencies. We present a model aimed at minimizing an objective function that encompasses delay penalties and the optimization of resource usage. Additionally, we introduce an optimized COS algorithm, named SCOS (Streamline COS), designed to find the optimal solution. The efficacy of this approach is validated through experiments with several datasets of varying sizes and instances, demonstrating that the Streamline COS method significantly enhances resource management, reduces delays, and optimizes order scheduling, while offering flexible priority management. This approach provides a practical and effective solution to complex scheduling problems and opens new research avenues, particularly in integrating dynamic constraints and leveraging optimization and machine learning techniques for further performance improvements.

Trihalomethanes are a group of chemical compounds that can contaminate drinking water. THMs are formed when the chlorine used to disinfect the water reacts with the natural organic matter present in the water. Mainly, their formation depends on pH, free residual chlorine, water temperature, and the concentration of natural organic matter.The objective of this work is to determine the impact of certain physicochemical parameters on the formation of trihalomethanes in the drinking water supplying the city of Sidi Bel Abbes.Physicochemical analyses of drinking water from three distribution networks supplying the city of Sidi Bel Abbes revealed that the pH values are around 7 and the temperature does not exceed 20°C. The analysis of organic matter in the collected samples shows variable results between areas, with organic matter concentrations in area 1 being slightly higher than those in area 2. The average concentrations of organic matter recorded in area 3 are lower compared to those in the other two sampling areas. Our results show that the free residual chlorine in the network directly contributes to the formation of disinfection by-products. This study aims to enhance knowledge of the spatio-temporal formation of trihalomethanes in drinking water distribution reservoirs.

We present the results from a detailed analysis of our time-series spectroscopic observations and the Transiting Exoplanet Survey Satellite (TESS) photometric data of the eclipsing binary V389 Cas. The radial velocities (RVs) of the primary and faint secondary components were obtained from a total of 61 high-resolution spectra made between 2016 and 2019. The disentangling spectra were used to determine the effective temperature and projected rotational velocity of the primary star based on the χ

Carbon-rich Wolf–Rayet (WR) binaries are a prominent source of carbonaceous dust that contribute to the dust budget of galaxies. The “textbook” example of an episodic dust-producing WR binary, WR 140 (HD 193793), provides us with an ideal laboratory for investigating the dust physics and kinematics in an extreme environment. This study is among the first to utilize two separate JWST observations, from Cycle 1 ERS (2022 July) and Cycle 2 (2023 September), to measure WR 140’s dust kinematics and confirm its morphology. To measure the proper motions and projected velocities of the dust shells, we performed a novel point-spread function (PSF) subtraction to reduce the effects of the bright diffraction spikes and carefully aligned the Cycle 2 to the Cycle 1 images. At 7.7 μm, through the bright feature common to 16 dust shells (C1), we find an average dust shell proper motion of 390  ±  29 mas yr−1, which equates to a projected velocity of 2714  ±  188 km s−1 at a distance of 1.64 kpc. Our measured speeds are constant across all visible shells and consistent with previously reported dust expansion velocities. Our observations not only prove that these dusty shells are astrophysical (i.e., not associated with any PSF artifact) and originate from WR 140, but also confirm the “clumpy” morphology of the dust shells, in which identifiable substructures within certain shells persist for at least 14 months from one cycle to the next. These results support the hypothesis that clumping in the wind collision region is required for dust production in WR binaries.

We use in situ measurements from the first 19 encounters of Parker Solar Probe and the most recent five encounters of Solar Orbiter to study the evolution of the turbulent sonic Mach number M

t
(the ratio of the amplitude of velocity fluctuations to the sound speed) with radial distance and its relationship to density fluctuations. We focus on the near-Sun region with radial distances ranging from about 11 to 80 R
⊙. Our results show that (1) the turbulent sonic Mach number M

t
gradually moves toward larger values as it approaches the Sun, until at least 11 R
⊙, where M

t
is much larger than the previously observed value of 0.1 at and above 0.3 au; (2) transonic turbulence with M

t
 ∼ 1 is observed in situ for the first time and is found mostly near the Alfvén critical surface; (3) Alfvén Mach number of the bulk flow M
A shows a strong correlation with the plasma beta, indicating that most of the observed sub-Alfvénic intervals correspond to a low-beta plasma; (4) the scaling relation between density fluctuations and M

t
gradually changes from a linear scaling at larger radial distances to a quadratic scaling at smaller radial distances; and (5) transonic turbulence is more compressible than subsonic turbulence, with enhanced density fluctuations and slightly flatter spectra than subsonic turbulence. A systematic understanding of compressible turbulence near the Sun is necessary for future solar wind modeling efforts.
Exploring the $ q $-analogue of Fibonacci sequence spaces associated with $ c $ and $ c_0 $

Published: January 2025

We have proposed a $ q $-analogue $ c(\mathcal{F}(q)) $ and $ c_0(\mathcal{F}(q)) $ of Fibonacci sequence spaces, where $\mathcal{F}(q) = (f^q_{km})$ denotes a $ q $-Fibonacci matrix defined in the following manner:

   \begin{document}$ f^q_{km} = \begin{cases} q^{m+1} \frac{f_{m+1}(q)}{f_{k+3}(q) - 1}, & \text{if } 0 \leq m \leq k, \\ 0, & \text{if } m > k, \end{cases} $\end{document}

for all $ k, m \in \mathbb{Z}^+_0 $, where $(f_k(q))$ denotes a sequence of $ q $-Fibonacci numbers. We developed a Schauder basis and determined several important duals ($ \alpha $-, $ \beta $-, $ \gamma $-) of the aforesaid constructed spaces $ c(\mathcal{F}(q)) $ and $ c_0(\mathcal{F}(q)) $. Additionally, we examined certain characterization results for the matrix class $(\mathfrak{U}, \mathfrak{V})$, where $\mathfrak{U} \in \{c(\mathcal{F}(q)), c_0(\mathcal{F}(q))\}$ and $\mathfrak{V} \in \{\ell_{\infty}, c, c_0, \ell_1\}$. Essential conditions for the compactness of the matrix operators on the space $ c_0(\mathcal{F}(q)) $ via the Hausdorff measure of noncompactness (Hmnc) were presented.
