Published: January 2025

Previous studies have reported that students with Islamic studies backgrounds in Malaysia often exhibit low performance in the English language, which is associated with negative attitudes and low motivation to learn the language. Many of these students question the need to learn the language, making it essential to investigate whether this issue persists in the current era. Therefore, the present study aims to study the problems that these students face in learning English grammar and how it influences their language learning at the tertiary level. A questionnaire was specifically designed and distributed to 61 students from the Faculty of Islamic Studies of a public university in Malaysia before transferring the data into Statistical Package for the Social Sciences (SPPS) for analysis. The results from the questionnaire reveal that even at the tertiary level, students still struggle with learning English. They felt that learning English was difficult as they could not find similarities between English and any other languages they knew. Moreover, their negative perception of the language hindered them from putting effort into improving their proficiency. Hence, it is recommended for a specific module to be designed for this group that can cater to their needs towards learning English grammar efficiently, with the hope that it will also positively change their perception of the language.

Non-communicable diseases (NCDs), including cardiovascular diseases, diabetes, chronic respiratory diseases, and cancer, pose significant public health challenges globally and in Malaysia. The Orang Asli, an indigenous community in Malaysia, faces unique health challenges due to socioeconomic disparities and lifestyle changes. This scoping review synthesizes existing literature on the prevalence and determinants of NCDs among the Orang Asli, aiming to identify research gaps and inform public health strategies. We conducted a systematic search across databases including PubMed, Scopus, Google Scholar, and Web of Science, identifying 15 relevant studies from an initial pool of 573 records, following PRISMA guidelines. The review reveals significant variability in the prevalence of hypertension (3.3% to 57.2%), diabetes mellitus (0.8% to 25%), and dyslipidaemia (1.5% to 41.4%) among the Orang Asli. Other conditions such as gout and asthma were noted with prevalences of 2.7% and 0.4%, respectively. Factors associated with NCD prevalence include older age, female gender, lower education levels, poor dietary habits, physical inactivity, smoking, obesity, genetic predispositions, and the impacts of urbanization and modernization. Addressing the NCD burden requires multifaceted strategies, including culturally sensitive health promotion, improved healthcare access, and the preservation of traditional practices. This review underscores the urgent need for targeted interventions to mitigate the rising NCD burden in this vulnerable population.

Authors: Dalwadi Pragnesh
Published: January 2025

The Upanishads are philosophical texts written in India over 2,500 years ago that explore fundamental questions on the nature of existence and consciousness. Central ideas include the Atman (individual soul), Brahman (supreme reality), Samsara (rebirth) and moksha (liberation). Inquiring past exterior rituals, the Upanishads turn inward, examining the crux of the human self and its relation to the universe. Through discourses and metaphors, they describe achieving spiritual visions of unity with the divine ground of being by transcending ego boundaries. Recommending spiritual paths from knowledge to meditation, their visions of transcendent states of consciousness and non-duality between self and universe have deeply impacted Indian philosophy and understanding of who we are.

Authors: Jadeja Drashtiba , Singh Sonu , Tripathi Shivam
Published: January 2025

Background: Hypertension is a major global health challenge and a significant risk factor for cardiovascular diseases (CVDs). Stress and autonomic nervous system (ANS) dysfunction play critical roles in its etiology. Non-pharmacological approaches, such as pranayama techniques, are increasingly recognized for their potential to manage hypertension. This study evaluates the effects of Sheetali and Bhramari Pranayama on systolic and diastolic blood pressure among male police personnel, a high-stress occupational group. Method: The study included 50 male police personnel diagnosed with hypertension. Participants were assigned to a two-month intervention involving daily practice of Sheetali and Bhramari Pranayama under supervision. Blood pressure levels, including systolic (SBP) and diastolic (DBP), were recorded pre- and post-intervention. Data were analysed using paired t-tests to assess the impact of the intervention. Results: The findings showed a significant reduction in both SBP and DBP following the pranayama intervention. The mean SBP decreased from 145.318 mmHg (SD = 6.034) to 140.440 mmHg (SD = 6.188), with a t-value of 19.036 (p < 0.0001). Similarly, the mean DBP decreased from 88.68 mmHg (SD = 4.47) to 84.00 mmHg (SD = 4.70), with a t-value of 19.66 (p < 0.0001). These results highlight the effectiveness of Sheetali and Bhramari Pranayama in managing hypertension. Conclusions: Sheetali and Bhramari Pranayama significantly reduced systolic and diastolic blood pressure among hypertensive male police personnel. These techniques offer a simple, cost-effective, and non-pharmacological approach to managing hypertension, particularly in high-stress occupational groups. Integrating pranayama into workplace wellness programs could improve cardiovascular health and overall well-being in law enforcement personnel.

Extent of Climate Information Service as a Decision Support Tool to Climate Smart Agricultural Technology Use and Adoption in Ghana
Authors: Damba Tahidu Osman
Published: January 2025

Climate information services have been crucial in the quest to promote sustainable agricultural production. Access to information is a first step in addressing such a situation. In this context, getting information on events, actions, situations, or happenings that threaten the achievement of sustainable agriculture production is the top most priority. Climate information received by farmers is critical to farmers decision making and planning process in the agriculture sector specifically with productivity, food security, plant and soil health. Use and adoption of CSA technologies by farmers is largely influenced by inherent decisions based on climate information at all stages of production. Based on this, 679 farmers across 6 regions in Ghana, rainfall onset, first cessation, windstorm, humidity, drought spell and rainfall volume were identified as the CI required in order of importance out of nine (9). Out of all the farmers that accessed this information, about 72% had information on rainfall onset being the highest, followed by first-cessation with 47%. This top 2 is largely possible because of the heavily dependence of rainfall on agriculture and through farmer-to-farmer information sharing, and much focus on rain related information. CSA adoption, a little above one-fifth (22%) of the farmers adopted crop rotation. Pest and disease tolerant varieties were adopted by 15% of the farmers, with a close to equal adoption percentage across all three sampled groups. Minimum tillage was reported as a male-dominant CSA and was only adopted by less than one-fifth of the total respondents. Enhanced biopesticide use was male dominant. CIS proves to be a critical tool for decision making and hence influence CSA use and adoption. This therefore requires strong improvement in both content, strategy and approach to delivering tailor-made CI for farmers and other value chain actors.
An Enhancement of Honey Encryption Algorithm Applied in Online Patient Portals
Authors: Agustin Ryan James , Concha Jhack Rowlan
Published: January 2025

The Honey Encryption Algorithm is a novel encryption scheme designed to encrypt messages using low-entropy keys, such as passwords. When an incorrect key is used for decryption, it returns a honeyword—a fictitious message intended to mislead attackers into thinking they have accessed the correct data. However, in password-based authentication systems, a usability issue arises when legitimate users accidentally input their password in a way that results in a honeyword. This study addresses the problem of typo-safety in Honey Encryption Algorithm by employing Long Short-Term Memory (LSTM) models combined with Damerau-Levenshtein distance metric to generate honeywords that are less likely to be typed by legitimate users, while still being effective against adversarial attacks. The Enhanced Honey Encryption Algorithm achieved a typo rate of 29%, with only 4.57% of typos producing a honeyword candidate. In comparison, the original Honey Encryption Algorithm using a Take-a-Tail method had a 71% typo rate, with 27.71% of typos resulting in honeyword candidates. A password survey was conducted on 100 participants, asking them to re-enter 20 passwords under timed and environmental constraints for ecological validity. Both algorithms were tested using honeyword sets generated from a set of passwords sourced from the phpBB password list. The Enhanced Honey Encryption Algorithm’s 29% typo rate and 4.57% honeyword rate indicate a lower probability of legitimate users’ typos resulting in a honeyword, resulting in a significant improvement in usability in password-based authentication systems.

El análisis mineral foliar se utiliza para determinar el estado nutricional de las plantas en muchos cultivos, pero en cultivos de árboles, como el durazno (Prunus persica L.), tiene un valor limitado para determinar la fertilización correctiva durante la temporada de crecimiento y se emplea principalmente para establecer los requerimientos de fertilización al inicio de la temporada siguiente. En contraste, el análisis mineral floral proporciona una medida más actualizada del estado mineral del árbol, permitiendo una intervención más oportuna para prevenir o, al menos, mitigar una variedad de desórdenes fisiológicos que afectan el rendimiento y la calidad del fruto en la cosecha. Este estudio correlaciona el estado nutricional de flores y hojas con parámetros clave del fruto para determinar si el análisis floral puede utilizarse para el diagnóstico y corrección de deficiencias de nutrientes a mitad de temporada. Se evaluaron siete cultivares de durazno (Prunus persica L.): ‘Baby Gold 8’, ‘Autumn L’, ‘Catherin’, ‘Fairtime’, ‘Carnaval’, ‘Baby Gold 5’ y ‘Arkansas’ muestreados de forma aleatoria simple contemplado diez unidades de muestreo por cultivar. Se encontró un mayor número de relaciones significativas entre los nutrientes florales y los atributos de calidad del fruto en comparación con los nutrientes foliares. Se concluye que el análisis mineral floral tiene un buen potencial para el diagnóstico y ajuste nutricional a mitad de temporada en los siete cultivares de durazno estudiados.

Flexible Manipulators (FMs) provide a number of benefits, containing reduced weight due to the thinness of the robot’s linkages. Although the initial plan was to use actual robots’ flexibility or slenderness to their advantage, the complex dynamics of the systems piqued interest in using an experimental flexible manipulator as a testing ground for various modeling or control strategies. A review is essential for researchers who want to align their study objectives with those of the field because the literature is extensive and diverse. Due to the widespread usage of flexible manipulators in different mechatronic and robotic applications over the past few decades, many academics worldwide are now interested in researching this topic. Studies are categorized here according to the control and modeling technologies of flexible manipulators and methodologies. Review of recent works on analysis, modeling, mechanical vibration, control algorithms, gyroscope technology and applications, difficulties in managing flexible manipulators and their anticipated future, and the majority of the notable evolutionary and optimization algorithms, including Genetic Algorithm (GA), Differential Evolution (DE), and Fuzzy Logic (FL), as well as modification approaches and techniques, are discussed and underlined. This study examines many publications, thoroughly reviewing the analytical, mathematical, dynamical modeling, mechanical vibration control techniques and most of the notable evolutionary and optimization algorithmic approaches of Robotic Flexible Manipulator (RFM) structures.

The Sultan Mahmud Airport runway extension in 2008 resulted in coastal erosion along the Kuala Nerus shorelines. In response, different breakwater systems were constructed to mitigate erosion. Despite previous reports highlighting the effects of breakwaters on marine organisms, the local impact remains uncertain. Therefore, this study investigates the spatial impact of different breakwater systems on macrobenthos composition in the Kuala Nerus coastal area. Samplings were conducted at 12 substations across five main stations, covering sheltered and exposed areas. Results revealed 27,137 macrobenthos individuals, with groyne exhibiting the highest macrobenthos composition (8448.79 ± 2813.73 ind./m2). Gastropoda dominated (4971.01–41608.70 ind./m2), followed by Bivalvia (2927.54–12391.20 ind./m2) and Polychaeta (1000.00–4956.52 ind./m2). Macrobenthos compositions in the sheltered and exposed stations differed significantly (p < 0.05). The coastal area is predominantly sandy (30.68%–77.32%) with relatively stable total organic matter (TOM) and heavy metal concentrations. Current speed and significant wave height (Hs) are lower in sheltered stations, while bathymetry is deeper in exposed stations (up to 8 m). The macrobenthos assemblages are influenced by soft-bottom characteristics and food availability, with the hydrodynamic stress from the breakwater system governing these two primary factors.

Published: January 2025

Most dams constructed worldwide are zoned earth dams with cores of different materials. However, selecting the proper core material in an earth dam will reduce seepage and increase safety. Most of the available information on dam cores was extracted from laboratory experiments. In this study, cores of different materials used in three selected zoned dams of almost the same height were assessed based on acquired field data and numerical simulation. The selected dams are in Iraq and named Haditha Dam (designed with a compound core of compacted dolomite and asphaltic diaphragm), Hemrin Dams (designed with a hard clay core) and Khasa Chai Dam (designed with a silty clay core). The total water head and water flux through the core of each dam were simulated using a two-dimensional SEEP/W model. For high and low water depths in the reservoir of Hemrin Dam, the water flux ratios were found to be 140 and 50 times greater than that of Haditha Dam. For low water depth in the reservoirs of Hemrin and Khasa Chai Dams, the flux ratio was 17. Compared with the core of the Hadith Dam, the flux through the core of the Khasa Chai Dam was found to be triple. For studied core samples, the variation in fluxes can be related to the effect of both hydraulic conductivity and geometry of the dam core. The hydraulic conductivity is affected by the core material, while the hydraulic gradient is affected by both the core material and geometry.

Published: January 2025

Joint torque estimation is an essential aspect of the control architecture in assistive devices for rehabilitation and aiding movement impairments. Healthy adult torque trajectories serve as a baseline for controllers to determine the level of assistance required by patients, evaluate impaired motion, understand biomechanics, and design treatment plans. Currently, methods of torque estimation include inverse dynamics using gold standard motion capture systems, generic mathematical models based on joint torque-angle relationships, neuromusculoskeletal modelling using surface electromyography, and neural networks. As such, this review provides a focused overview of the recent and existing neural networks tailored for upper and lower limb joint torque estimation. Dataset preparation, data preprocessing, and evaluation metrics are presented along with a detailed description of the developed networks, which are classified by model architecture. It includes artificial neural networks (ANNs), convolution neural networks (CNNs), long short-term memory (LSTM) networks, and hybrid and alternate architectures such as wavelet or explainable convolution (XCM). The performance, benefits, and limitations of the models are discussed, highlighting CNNs and LSTMs as the current optimal models for time series prediction of joint torque. This is due to their ability to capture spatial and temporal dependencies in the data. Additionally, joint kinematics such as angles, angular velocities, and accelerations are considered optimal input parameters due to their ease of measurement using wearable sensors and integration with wearable assistive technology.
