RUDE: Fusing Rules and Deep Learning for High-Speed Drone Path Planning
Authors: Zheng Yan , Li Yanran , Zhang Yanan , Lian Shixi , Wen Yongming , Yu Yue
Published: January 2025

This paper focuses on the problem of emergency restricted zone avoidance for high-speed drones. Existing path planning methods struggle with inefficiency due to large search spaces, slow convergence rates, and difficulties in path planning for high-speed drones. To overcome these challenges, we propose a novel approach that integrates rules with deep learning. This hybrid approach simplifies decision-making by converting temporal decisions into a limited set of middle way-points, significantly reducing the complexity of both the state and solution search space. Additionally, rules are employed to prevent aimless exploration within the solution space. To enhance the algorithm performance, we introduce a situation prediction model, which is trained to capture the relationship between way-points and flight outcomes, such as restricted zone encounters and energy consumption. Experimental results demonstrate notable improvements over purely rule-based methods, with high success rates in avoiding restricted zones and maintaining sufficient kinetic energy to reach the goal.

Authors: Li Qi  , Kamaruddin Norshaliza , Gong Xun , Peng Chen
Published: January 2025

This paper introduces a novel deep learning framework and integrates symbolic genetic programming (SGP) to predict cross-sectional stock return rankings. The data of this framework covers more than 4,600 Chinese listed stocks and Japan from 2014 to 2022 for comparison. Leveraging the S&P Dataset for both countries, the hybrid model absorbs the algorithm of data augmentation and novel DNN framework. The research showcases substantial enhancements in Rank IC by 588.03% in China and 194.27% in Japan, respectively. Moreover, a simple rule-based investment strategy based on the application of the SGPLSTM model in China achieved an annualized return of 22.35% exceeding the index (CSI 300) and 16.26% compared to CSI 500 index in China, respectively, and surpasses the N225 index by 4.56% and the TPX index by 5.10% in Japan. These results fully demonstrate that SGP combined with the LSTM model can greatly improve the precision and accuracy of cross-sectional stock selection and also provide very valuable guidance to financial analysts, fund managers and traders.

Published: January 2025

Hikikomori syndrome is no more a Japanese phenomenon as it has been rapidly spreading across the globe, especially in South Asian countries. Among those individuals who tend to confine themselves within the walls of their homes, internet addiction has turned out to be a major component further fueling the isolation. Objectives: To explore the association between internet addiction and Hikikomori symptoms and to assess gender differences in Hikikomori symptoms and internet addiction. Method: This cross-sectional research study assessed 318 individuals attending a private university in Lahore. The participants for this study were selected through a non-probability purposive sampling technique and included 23% men and 75% females, and 1.6% selected '3'(rather not say) while two respondents did not provide gender information. Structured measures with well-established psychometric features were used to collect data. Results: Participants who felt socially isolated and lacked emotional support might have stronger internet addiction (p<0.05). Meanwhile, there weren't big differences between men and women in how isolated they feel (p>0.05), but men scored significantly higher than women on the socialization and emotional support domain (p<0.05). Men also tended to be more addicted to the internet than women (p<0.01) in the present study. However, demographic variables when correlated with Hikikomori and internet addiction, showed varying patterns of association. Conclusions: It was concluded that findings provided significant insights into internet addiction and socialization, isolation and emotional support dimensions of hikikomori syndrome in young adults in Lahore.
Breaking Barriers in Mental Health: Novel Targets and Therapies for Depression and Anxiety
Authors: Bashir Muhammad Irfan
Published: January 2025

Depression and anxiety are among the most prevalent mental health disorders, posing significant challenges to individuals and society. Despite the widespread use of selective serotonin reuptake inhibitors (SSRIs) and serotonin-norepinephrine reuptake inhibitors (SNRIs), many patients fail to achieve full remission or encounter debilitating side effects. This underscores an urgent need for innovative therapeutic approaches that go beyond traditional monoaminergic systems, targeting new pathways and mechanisms involved in these complex disorders.
Recent advances have highlighted promising therapeutic targets, including the glutamatergic system. Ketamine, an NMDA receptor antagonist, has demonstrated rapid and sustained improvements in mood, inspiring the development of drugs that modulate glutamate transmission. Other systems, such as neuropeptides like oxytocin and vasopressin, are gaining attention for their roles in emotional regulation, while the endocannabinoid system offers potential for regulating mood and stress response [1].
Another recent study have shown that ketamine may offer significant benefits for individuals with psychiatric conditions such as treatment-resistant bipolar depression. Evidence suggests that even a single dose of intranasal ketamine can produce swift antidepressant effects, offering an alternative option for patients unresponsive to standard treatments [2]
These novel approaches bring significant challenges with them. The safety profile of new agents must be rigorously evaluated to avoid unintended consequences, and regulatory barriers can delay the availability of innovative therapies. Moreover, the heterogeneity of depression and anxiety, influenced by genetic, environmental, and social factors, highlights the need for personalised medicine. Future research must prioritise understanding these differences to optimise treatment outcomes for diverse populations.
The exploration of novel targets and drugs signals a paradigm shift in the treatment of depression and anxiety, moving away from a one-size-fits-all approach toward tailored interventions. These advancements bring renewed hope to millions of patients worldwide, promising more effective, rapid, and sustainable relief. With ongoing research and careful clinical translation, these innovative therapies have the potential to transform mental health care in the coming decades.

Published: January 2025

This study examines the awareness and implementation of the gender-responsive basic education policy (GRBEP) in public secondary schools in Cabuyao City, Philippines. Additionally, this research aims to identify areas for improvement in GRBEP implementation and practice within public secondary schools in Cabuyao City, ultimately contributing to the development of a roadmap for optimization of improvement plan. Utilizing a quantitative, descriptive, and correlational research design, we assessed GRBEP integration through a two-part questionnaire administered to 380 students and 280 employees (teaching and non-teaching staff).
The questionnaire evaluated their awareness and implementation of GRBEP principles across six key areas: learner development, curriculum standards, learning delivery, learning environment, learning resources, and assessment. Statistical analysis, including mean, standard deviation, Mann Whitney U test for significant differences, and Spearman Rho for correlation, was conducted. The findings reveal a significant relationship between the level of awareness and the level of GRBEP implementation among students and employees. Thus, when students and employees were more aware on GRBEP, the policy is well implemented.

Electronic crimes, such as cyberbullying are major contributors to workplace harassment in Pakistan, affecting the mental and physical health of victims. Such crimes create a toxic work environment, reducing productivity. Harassment in Pakistan is a societal issue that, with its deep-rooted cultural, institutional, and legislative difficulties, is ever-prevalent. This has not only undermined the self-respect and well-being of victims but also has caused deep physio-psychological effects. Individuals of workplace harassment experience a series of physical as well as psychological symptoms such as anxiety, stress-related disorders, depression, and weakened self-esteem leading to declined job satisfaction, increased absenteeism, and lower performance causing great challenges for individuals and organizations. The socio-cultural perspective of Pakistan, with its gender norms and ordered structures, worsens the problem, especially for women and downgraded groups. The harassment incidents are usually underreported due to social humiliation, insufficient support systems, and fear of revenge. Also, lack of training and awareness on workplace conduct and the rights of workers cause a culture of liberty for criminals. To address the harassment challenges, Pakistan has taken legislative initiatives like the Protection Against Harassment of Women at the Workplace Act, of 2010. The Act supports handling complaints and sets out punishments for culprits of harassment. However, despite the legislative measures, and awareness programs the effective execution/implementation of laws remained a major challenge due to which harassment is rapidly prevailing in Pakistani society, particularly targeting women and poor people populations. Most organizations lack the essential infrastructure and/or commitment to completely obey these guidelines. Therefore, there is a need for continuous training and education to nurture a workplace culture that upholds equality and respect. Supporting networks for the victims and cybercrime awareness campaigns can play an important role in inspiring more individuals to come forward for justice. Enhancing the capacity of institutions to implement these laws, promoting gender-sensitive training, and fostering an inclusive workplace culture is crucial for mitigating the physio-psychological impacts of harassment and ensuring a safe and equitable work environment for all employees. Existing legislation addresses cybercrime and harassment, but stronger policies are needed to protect workers better. This paper explores the impact of electronic crimes on workplace harassment and legislative efforts to address these issues.

The jump in journal impact factors during this pandemic
Authors: Zou Qiang , Ni Ming
Published: January 2025

Background: Due to the impact of coronavirus disease 2019 (COVID-19), a significant number of COVID-related papers have been published. The journal citation report (JCR) of Web of Science, released in June 2022 and 2023, demonstrated that the journal impact factors (JIFs) of biomedical journals have increased substantially. Methods: This study examined two traditional multidisciplinary journals (Science and Nature) and four medical journals (The Journal of the American Medical Association [JAMA], The Lancet [LANCET], The New England Journal of Medicine [NEJM], and British Medical Journal [BMJ]). The influence of COVID-related papers on JIFs was analyzed using bibliometric methods. Results: The proportion of citations in 2021 to items published in 2020 was notably high, with five journals exceeding 50%. Similarly, the proportion of citations in 2022 to items published in 2020 and the proportion of citations in 2022 to items published in 2021 remained high, although exhibiting a gradual downward trend. Conclusion: The JIFs of the four medical journals were higher than those of the top traditional multidisciplinary journals Science and Nature by a wide margin. This discrepancy could be attributed to the larger denominators (citable items) in the JIF calculations for Science and Nature or other factors. However, in terms of average citations per paper, there was no evidence that Science and Nature performed worse than the medical journals. Emerging hot topics, such as COVID-19, tend to elevate JIFs considerably. However, it is important to adopt a rational perspective on these surges. The publication of scientific and technological papers should prioritize advancing human knowledge through academic exchange rather than focusing solely on JIFs values.

Authors: Адамів М. Є. , Ганас В. С.
Published: January 2025

В сучасних умовах гострого дефіциту фінансового забезпечення діяльності вітчизняних суб’єктів господарювання управління різними видами фінансових ресурсів набуває особливої актуальності, оскільки дає змогу забезпечити оптимальне співвідношення власних, позичених та залучених ресурсів на засадах їх ефективного формування та використання. Метою дослідження є конкретизація процесу управління фінансовими ресурсами підприємства на основі побудови уніфікованої послідовності його ключових етапів та розкриття змістової структури кожного такого етапу. Для досягнення мети дослідження було застосовано процесно-структурований підхід до управління, який за інноваційним принципом поєднує різні підходи до управління і таким чином розширює процесний підхід шляхом обґрунтування змістової структури кожного етапу управлінського процесу. Для виконання конкретних завдань дослідження було використано такі методи, як групування та узагальнення, морфологічного аналізу, процесний підхід, структурної декомпозиції. У цілях дослідження фінансові ресурси систематизовано за джерелами їхнього формування на власні, позичені та залучені. Встановлено, що управління фінансовими ресурсами є цілеспрямованою діяльністю, яка передбачає ідентифікування, оптимальне накопичення та ефективне використання власних, залучених і позичених фінансових ресурсів для забезпечення потреб виробничо-господарської діяльності підприємства та досягнення його позитивного й стабільного фінансового стану. Управління фінансовими ресурсами підприємства на основі імплементації процесно-структурованого підходу слід розглядати як конкретну функцію менеджменту, яка реалізовується відповідно до класичної послідовності управління (виконання функцій управління, формування методів управління та розроблення управлінських рішень), однак кожен її етап характеризується конкретною змістовою структурою відповідно до специфіки діяльності підприємства. Дослідження має теоретичний характер, оскільки розкриває методологічні засади побудови процесу управління фінансовими ресурсами на підприємствах із обґрунтуванням змістової структури кожного етапу управлінського процесу. Практична цінність одержаних результатів дослідження полягає у можливості використання керівниками підприємств запропонованої послідовності управління фінансовими ресурсами для удосконалення їхніх існуючих управлінських механізмів на засадах забезпечення цілісності та завершеності. Представникам апарату управління слід врахувати, що при незмінній послідовності етапів процесу управління фінансовими ресурсами їхня змістова структура може змінюватись залежно від специфіки діяльності підприємства, що вимагає врахування та аналізування чинників внутрішнього та зовнішнього середовища.
The Sociological Explanations of Mental Health: Insights from Goffman, Foucault, and Giddens
Authors: Alharbi Najwa
Published: January 2025

The sociological perspective on mental health is essential for understanding the characteristics of individuals with mental illness, the underlying causes, and potential remedies. However, there is a lack of Arabic studies that explore the definitions of mental health and illness through the lens of contemporary social theorists such as Goffman, Foucault, and Giddens. Various theorists have proposed differing explanations of mental illness from sociological viewpoints. This study aims to provide a theoretical framework for understanding definitions and responses to mental health from these sociological perspectives. Specifically, the paper analyzes the views of different philosophers regarding mental health and illness, focusing on the insights of contemporary theorists like Goffman, Foucault, and Giddens. The findings indicate that these theorists offer valuable perspectives on mental health. Each utilizes distinct theories to illustrate mental health issues causes, treatment, and consequences. For instance, Goffman employs the theory of stigma, Foucault focuses on the theory of social power, and Giddens discusses the theory of structuration. Moreover, all three theorists agree that mental illness is influenced by social factors, including social stigma, societal perceptions, social roles, and norms, as well as individuals' social and economic status.

The rapid depletion of global resources and the increasing challenges associated with waste management have underscored the importance of the circular economy—a framework designed to balance resource utilization, align production with consumption, and effectively address waste-related issues. Within this context, social complementary factors in waste management are crucial for overcoming these significant challenges. This study investigates the current state of solid waste management within the circular economy, with a particular focus on socio-cultural and behavioral dynamics, as well as the socio-technical implications of these processes. The research aims to elucidate the influence of socio-cultural dynamics on waste management practices. A comprehensive search of the Web of Science (WoS) database, using the keyword “solid waste management” up to August 10, 2024, yielded 33,247 relevant studies. To extract key themes from this extensive body of literature, Latent Dirichlet Allocation (LDA) topic modeling was applied. Subsequently, BERT-based deep learning methods were employed for text classification to identify which socio-cultural dynamics are most emphasized in the selected studies. The model achieved an overall accuracy of 87.5% in predicting the dominant topics. The findings from this study provide significant insights into the socio-cultural factors influencing waste management practices within the circular economy. By identifying these dynamics, the research contributes to a deeper understanding of how social and cultural factors can be leveraged to enhance the effectiveness of waste management strategies.

Coffee is a superior plantation commodity playing an important role in Indonesian economic growth, as a contributor to income and provider of employment. The handling process of coffee, particularly at roasting stage, has a significant impact on the quality of the final product. The Research Center for Appropriate Technology, National Research and Innovation Agency, has developed fluid-type roasting machine with a capacity of 750 grams (g) and fueled by LPG (liquefied petroleum gas). Therefore, this research aimed to determine the characteristics of robusta roasted coffee through performance tests of fluid-type roasting machine. Performance tests were carried out to determine the static characteristics of temperature sensor and ensure accurate provision as well as consistent readings in effectively controlling roasting process. Some of the characteristics that were determined included moisture content by thermogravimetric method, color, texture, caffeine, and microscopic analysis. The results showed that fluid-type roasting machine had a high-temperature sensor accuracy of 1.3% and repeatability of 0.69. The physical and chemical analysis showed that roasting temperature significantly affected the characteristics of roasted coffee beans. Additionally, higher temperature caused an increase in cracking of coffee beans, ash content, texture, caffeine content, and darker color, along with lower moisture content.

Maintaining soil sustainability to increase and sustain land productivity can be achieved by minimizing synthetic fertilizers and maximizing organic fertilizers and biofertilizers, especially in suboptimal lands. Therefore, this study aimed to determine the effects of organic fertilizers and biofertilizers with reduced NPK (Nitrogen, Phosphate, Potassium) dosage on increasing rice yield in tidal swamp areas in Tebas Sungai Village, West Kalimantan. The procedures were carried out using a complete randomized block design, with several treatments consisting of 175 kg ha-1 NPK as a control (P0), 130 kg ha-1 NPK + 1.5 tons ha-1 cow manure (P1), 130 kg ha-1 NPK + 3.0 tons ha-1 cow manure (P2), and 130 kg ha-1 NPK + 25 kg ha-1 biofertilizers (P3). Based on assessment, the study area was then categorized as C overflow type. The results showed that the combination of NPK synthetic fertilizers with cow manure led to a 15.1%, 25%, 5.6%, and 5.4% increase in total tillers, total grains per panicle, weight of 1000 grains, and rice yield, respectively. In addition, the use of NPK fertilizers with biofertilizers increased total tillers, total grains per panicle, weight of 1000 grains, and rice yield by 24.6%, 56%, 7.7%, and 18%, respectively, compared to only NPK fertilizers. Based on these results, improving rice performance in tidal swamp areas could be achieved by integrating organic or biofertilizers with synthetic fertilizers.

Recycling is important for achieving environmentally sustainable products and waste reduction. The trend has led to the addition of reinforcement to recycling process to ensure the effective usage of wasted papers. Therefore, this study was conducted to determine the effect of using cellulose nanofiber (CNF) synthesized from kapok fibers as reinforcement in recycled papers. CNF was applied at different concentrations of 2, 4, 6, 8, and 10% of recycled paper production and the analysis was conducted by testing tensile index, density, and brightness. Moreover, X-ray diffraction (XRD), Fourier Transform Infrared Spectroscopy (FTIR), and UV-Vis analysis were used to determine the characteristics of the paper. The results showed that CNF addition influenced tensile index, brightness, and density of recycled papers. This was observed from an increase in tensile strength by up to 76.32% and density at approximately 0.58 g/cm3 for 10% CNF addition. Meanwhile, the brightness level was reduced due to the compact nature of paper produced. The trend led to the conclusion that the addition of CNF could impact the characteristics of recycled papers.

High levels of ferritin and adherence to low iron chelation are associated with the incidence of dyslipidemia. This process potentially causes some harmful effects, such as atherosclerosis. However, the correlation between ferritin level and lipid profile in thalassemia is still widely varied. The aim of this research was conducted to study the relationship between ferritin level and lipid profile. This research was a cross-sectional study involving 35 patients aged 5-18 years, diagnosed with transfusion-dependent thalassemia at Dr Soetomo General Hospital, Surabaya, Indonesia in November 2022. The sample was chosen by a consecutive non-randomized sampling technique. Patients previously diagnosed with dyslipidemia, diabetes mellitus type 1 and 2, metabolic syndrome, and having a history of anti-dyslipidemia medication and corticosteroids were excluded. Data were obtained from the medical record. Subsequently, the blood sample was drawn before the patients received any blood transfusion and examined for ferritin, total cholesterol, LDL, HDL, Triglyceride, apoA, and apoB levels. The data was analysed descriptively and the correlation between ferritin level and lipid profile was analysed statistically using Spearman, Pearson, and Chi-Square. According to the statistical analysis, a significant correlation was found between ferritin and LDL level (p = 0.013; coefficient correlation = 0.414), and total cholesterol (p = 0.006; coefficient correlation = 0.457). Meanwhile, ferritin level was not significantly related to high-density lipoprotein (p = 0.283), triglyceride (p = 0.131), apolipoprotein A (p = 0.83), apolipoprotein B (p = 0.26). Ferritin level was correlated significantly to LDL and total cholesterol level.

A new device for enhancing the physicochemical properties of diesel fuel to improve the combustion process and the operational and environmental performance of diesel power plants (DPP) of agricultural machinery (AM). During regular operation, DPP indicators are decreased due to various factors including the formation of carbon deposits on the surfaces of parts, causing AM to no longer meet efficiency and environmental standards. The conducted analysis of the AM operation showed that the thermal stress of the parts is increased as a result of forming carbon deposits in the combustion chamber of the DPP. To address this issue, the proposal is to utilize a technical liquid (water) that will be directed to the combustion chamber of the DPP. This process will effectively clean the surface of the carbon deposits and prevent their future formation through the microwave action of the steam-air mixture prepared in the intake manifold. For this purpose, a device has been developed to be installed on board the SHT, integrated into the standard fuel system, allowing the preparation of watered diesel fuel. As a result of complex dynamic processing, a highly dispersed emulsion is prepared from diesel fuel and water, the combustion of which in the combustion chamber of the DSU allows for the complete removal of the formed carbon deposit. The findings show that utilizing the developed device will improve the operational and environmental performance of the DSU, increase the capacity of old equipment by up to 15%, reduce specific fuel consumption by up to 18%, and the soot content in the exhaust gases by up to 14%.
