ENDOTHELIAL DYSFUNCTION AS A MARKER OF VENOUS THROMBOEMBOLISM RISK IN PATIENTS WITH ACUTE CALCULOUS CHOLECYSTITIS
Authors: Zhylinsky A. , Pavlyshyn A.
Published: February 2025

Thromboembolic complications are a significant issue in modern medicine, being one of the leading causes of mortality and disability. Their prevalence in the general population ranges from 0.15 % to 2.1 %, with a mortality rate reaching 2.1-6.2 %. An analysis was conducted on the diagnosis and treatment of 300 patients who underwent laparoscopic surgery for gallstone disease at the Regional Center for Elective Surgery and Transplantology of Rivne Regional Clinical Hospital named after Y. Semenyuk between 2019 and Patients were divided into two groups: Group I included 162 patients (54%) who received prophylaxis for venous thrombosis after laparoscopic cholecystectomy according to approved thromboprophylaxis protocols, and Group II comprised 138 patients (46 %) who underwent prophylaxis based on a newly developed algorithm during the study. Minimal risk (0 points) was observed in 57 cases (19 %), low risk (1–2 points) in 204 cases (68 %), moderate risk (3-4 points) in 31 cases (10.3 %), and high risk (≥5 points) in 8 cases (2.7 %). Patients stratified according to J. Caprini's model exhibited differences in von Willebrand factor levels. In the control group, post-laparoscopic cholecystectomy (LCE) values ranged from 104.2±3.3 (p<0.05) to 122.9±3.2 (p<0.05) in patients with acute calculous cholecystitis, and from 287.4±3.1 (p<0.05) to 291.4±3.2 (p<0.05) in those with acute cholecystitis and varicose vein disease. The total blood oxyproline level in patients with connective tissue dysplasia exceeded normal values by 42.13 %. This finding indicates possible excessive collagen synthesis and/or insufficient degradation, potentially associated with pathological changes in connective tissue.
STRUCTURE AND METABOLISM OF THE SKIN IN IODINE DEFICIENCY COMBINED WITH GOITROGEN CONSUMPTION
Authors: Honcharuk V. , Popadynets O.
Published: February 2025

Iodine deficiency, combined with the consumption of natural  goitrogens, such as soy and peanuts, which inhibit thyroid peroxidase activity, disrupts thyroid hormone synthesis. The disruption, in turn, results in structural and metabolic imbalances within the body. These conditions frequently occur due to the combination of endemic factors and specific dietary habits. Skin manifestations are among the earliest indicators of thyroid imbalance. However, scientific evidence on the sequential development of morpho-functional skin changes in iodine deficiency combined with goitrogen consumption remains limited, particularly concerning age-related characteristics and skin types (thin or thick). Therefore, this study aimed to examine the structural and metabolic changes in the back and paw skin of experimental animals throughout the progressive development of iodine deficiency combined with goitrogen consumption in postnatal ontogenesis. The experiment was conducted on 50 white non-pedigree rats, including 25 sexually immature animals (3-5 months old) and 25 sexually mature animals (6-8 months old). Eleven animals from each age group constituted the control group (Group 1). In contrast, 14 animals from each age group were allocated to the experimental groups (Groups 2 and 3) and exposed to iodine deficiency combined with soy and peanut consumption.
Tissue samples were collected on days 60 and 90 of the experiment. The research material included depilated skin from the back and metatarsal pads, their homogenates, and blood and urine samples. Morphological, morphometric, and biochemical analyses were conducted using statistical data processing. The study revealed alterations in the epidermal structure and keratinization processes. In the back skin of immature animals, the epidermal thickness on day 60 of the experiment was 3.1 % below the age norm (p˂0.001), and by day 90, it decreased to 5.5 % (p˂0.001). In mature animals, the epidermis was thinned by 1 % and 2.5 % (p˂0.01) on days 60 and 90, respectively. In the paw skin, the epidermis slightly thickened over the observation periods in mature animals, whereas in immature animals, it thinned by 6.5 % by day 90 (p˂0.001). In the edematous dermis, the volumetric density of collagen and elastic fibers changed according to changes in hydroxyproline and elastase content. Thus, the induced condition, validated by a significant reduction in urinary iodine concentration, disrupted thyroid homeostasis, resulting in morpho-functional changes in both thin and thick skin across all experimental animal groups.
ANATOMICAL FEATURES OF THE PERINEUM IN THE FETAL PERIOD OF ONTOGENESIS
Authors: Proniaiev V. , Tsyhykalo O.
Published: February 2025

The perineum is an area located between the muscular structures of the gluteal and femoral regions. Thus, the perineum externally resembles the shape of a rhombus and has the following borders: in front it is surrounded by the  pubic symphysis, branches of the pubic and sciatic bones; behind – by the lower edges of the gluteus maximus muscles, the coccyx and the sacrotuberous ligament. On the sides – by the sciatic tubercles of the sciatic bones. The conditional line, which passes between the two gluteal tubercles and lies on the tendon center of the perineum, divides the rhomboid section of the perineum into two triangles: the anterior urogenital and posterior excretory triangles.
Purpose: to determine the features of the morphogenesis of the muscular-fascial elements of the male perineum, the projection-syntopic and topographic-anatomical relationships of its structures during the fetal period of human development. Material and methods. 30 preparations of fetuses aged from 14 to 37 weeks of intrauterine development (IUD) (86.0-358.0 mm. parieto-coccygeal length) (TCL) were used. For a comprehensive study of the muscles of the superficial and deep group, fascial structures and spaces of the perineum, a series of sagittal sections of the perineum section along the midline were performed.
Results of our own research. One of the most important questions that scientists face when examining the deep perineum is whether the upper fascia of the urogenital diaphragm exists as a separate, discrete fascial structure, or whether it arises indirectly through the fusion of connective tissue sheets of neighboring structures.
Thus, we have found that the upper fascia of the urogenital diaphragm is not a discrete, separate fascial unit, but is partially formed by part of the connective tissue fibers of the prostate capsule and is a continuation of the lower fascia of the pelvic diaphragm, which covers the levator ani muscle from below.
Conclusions. 1. we found that the muscle fibers of the posterior part of the bulbospongiosus muscle are intertwined with the fibers of the perineal body, and the anterior part, covering the bulb of the penis, passes into the area of the cavernous bodies and intertwines with the fibers of the gluteal-cavernous muscles. 2. Additional attachments of the erectile elements and muscle fibers of the bulbospongiosus muscle to the perineal membrane were found. 3. It was noted that in addition to its own circular fibers, the external urethral sphincter muscle receives additional fibers from the deep transverse muscle of the perineum. 4. The upper fascia of the urogenital diaphragm is partially created at the expense of part of the connective tissue fibers of the prostate capsule and is a continuation of the lower fascia of the pelvic diaphragm.
Theyyam as a Ritualistic Catharsis: Cultural Trauma, Collective Memory, and Socio-Religious Subversion in Kerala
Authors: A R Mekhana
Published: February 2025

This paper examines the folk ritual of Theyyam in Kerala as a site of collective trauma, cultural memory, and social protest. Drawing from interdisciplinary perspectives—including anthropology, psychoanalysis, trauma studies, and postcolonial theory—this study argues that Theyyam functions as a cathartic and therapeutic medium for historically marginalized lower-caste communities in Kerala. The performance of Theyyam not only reenacts past injustices but also allows for a temporary inversion of social hierarchy, thereby enabling the oppressed to embody divine agency. This study explores how the ritual serves as a socio-political critique, a site of communal healing, and a mechanism for intergenerational trauma processing. By integrating insights from Cathy Caruth’s trauma theory, Johan Galtung’s structural violence framework, and Pierre Bourdieu’s concept of social capital, this paper situates Theyyam within the broader discourse of cultural resistance and resilience.
Distortion Behaviour Analysis of Additively Manufactured Inconel 718 using Numerical Computation
Authors: Mat Muhd Faiz
Published: February 2025

Metal Additive Manufacturing (MAM) is a rapidly growing technology
that has the potential to revolutionize the manufacturing industry. One
of the current MAM processes is direct energy deposition (DED), which
uses layer-by-layer deposition to design for part consolidation and
minimize materials wastage. However, repeated heating and cooling of
the DED process often exhibit distortions in AM components, leading to
premature failure. The study presents the numerical computation
analysis of the thermally induced distortion of additively manufactured
Inconel 718 on SS316 substrate utilizing the DED process with the help
of numerical computation software Simufact Welding. The geometry
design of the Inconel 718 component and SS316 substrate is designed to
establish a deeper understanding of the LMD process’s distortion
behaviour. The simulation results show that the distortions increase with
the number of layers, and the distortion rate varies along the deposition
height. Deformation of the substrate at nodes S3 and S5 increased
linearly in each of the deposited layers, but the rate decreased at nodes
S1 and S2 during the last four layers suggesting temperature uniformity
between the substrate and the deposited material.
Position Tracking Control of an Electromechanical Hip-KneeAnkle-Foot Orthosis
Authors: Abd Kadir Zulkiffli
Published: February 2025

The walking ability of the elderly is a major global health concern. Most
of the elderly experience walking difficulties such as decreased walking
speed and loss of balance as well as coordination. To address this issue,
a mechanical orthosis called the hip-knee-ankle-foot orthosis (HKAFO)
has been designed to assist elderly individuals and hospital patients in
performing therapeutic treatments. However, the existing standard
HKAFOs have several limitations including high energy consumption
and overloading of the hip and lower limb joints during walking
activities. Therefore, this study aims to enhance the standard HKAFO
by developing an electromechanical HKAFO (EM-HKAFO). The study
involves developing a two-degree-of-freedom mathematical model of a
double pendulum using Lagrange formulation to represent the HKAFO
structure and evaluate the kinematic motions of the lower limbs. The
performance of the proposed walking aid is evaluated using an actual
instrumented EM-HKAFO focusing on its effectiveness in achieving a
desired walking angle of 25º. The result indicates that the difference
between simulation and experimental data is within an acceptable error
range of 14%. Overall, this study contributes to the advancement of
mobility aids and enhances the quality of life for elderly individuals and
patients in need.
The Effect of Poly(butylene adipate-co-terephthalate) (PBAT)/ Oil Palm Frond (OPF) Composite with Palm Stearin as Compatibiliser
Authors: Subuki Istikamah
Published: February 2025

The chemical composition of palm stearin (PS), with its highly saturated
fats and triglycerides, makes it a potential candidate to serve as a
compatibilizer. This study investigated the effect of PS as a
compatibiliser on the thermal and mechanical properties of
poly(butylene adipate-co-terephthalate) (PBAT)/oil palm frond (OPF)
composites. In this paper, a biodegradable composite was prepared by
blending the PBAT with OPF as a filler, where it was subsequently
mixed with PS as a compatibiliser. A mixture of PBAT, OPF, and PS
was melted using an internal mixer at 160 ℃ and 60 rpm for 12 minutes.
The various formulations were then subjected to torque evaluation and
thermal and mechanical analysis to characterise the samples. The torque
analysis indicated that the PBAT was compatible with 30 wt.% OPF.
The chemical bond between PS, PBAT, and OPF is responsible for the
decrease in the melting point and degradation temperature of the
PBAT/OPF composite with increasing PS concentration. The presence
of PS in the PBAT-OPF composite improved its flowability and
moulding process. Accordingly, the tensile strength and ductility
showed improvement with the addition of 7.5% PS in the
PBAT70/OPF30 composite. Meanwhile, the addition of PS resulted in a
decrease in Young's modulus. The results indicated the suitability of the
PS as a compatibiliser for the PBAT/OPF composite.
Direct Integration Mode Superposition: A Simple Method for Dynamic Analysis of Submerged Floating Tunnel (SFT)
Authors: Akma Jamiatul
Published: February 2025

This article describes the use of simple methods to analyze the dynamic
behavior of large-dimensional structures, such as submerged floating
tunnels (SFT). Using this method the calculation process becomes
simple and inexpensive because the solution can be obtained
analytically. Based on the superposition mode method, it is possible to
directly integrate the Euler-Bernoulli beam theory model, which is
called the Direct Integration-Mode Superposition Method (DI-MSM).
Using Hamilton's principle, the equation of motion in the EulerBernoulli Beam model is modified into the Equation of forced damped
vibration. The solution of the equation is obtained by direct integration
to obtain the displacement and natural frequency. Evaluation of the
effectiveness of this method was confirmed by solutions using FEM as
validated with previous studies. This method is simpler to be applied in
analyzing other structures, especially continuous structures with large
dimensions, which if using the FEM method will require relatively large
computational costs and longer time.
Enhanced diagnosis and monitoring of broken rotor bar faults in induction motors using a combined ceemdan-mlp approach
Authors: Cherif Bilal Djamal Eddine , Rahali Hilal , Seninete Sara
Published: February 2025

This paper presents a novel approach for diagnosing and monitoring Broken Rotor Bar (BRB) faults in induction motors through vibration signal analysis. The method integrates advanced signal processing techniques such as the Hilbert Huang Transform (HHT) with machine learning methods, specifically Multilayer Perceptron (MLP). The study initiates with an HHT application to identify fault-related harmonics, achieved through complete Empirical Ensemble Mode Decomposition with Adaptive Noise (CEEMDAN) of the vibration signal (Vx), producing intrinsic mode functions (IMFs). A statistical analysis, employing correlation coefficients (CC), facilitates the selection of relevant IMFs indicative of BRB faults. IMFs with CC values equal to or greater than 0.2, notably IMF1, IMF2, IMF3, and IMF4, appear informative. Following IMF selection, signal reconstruction ensues by incorporating these useful IMFs. After rebuilding the signal, we use global thresholding based on a statistical analysis that includes Root Mean Square (RMS) and Energy Coefficient (EC) calculations. The Signal Reconstruction Denoising (SRD) meets the criteria for selection. Spectral envelope analysis of SRD is then employed for BRB fault detection. The subsequent phase employs a Multi-Layer Perceptron (MLP) for BRB localization. Features utilized for training the MLP model include EC and various frequency components ( fvb–, fvb+, 2fvb–, 2fvb+, 4fvb–, 4fvb+, 6fvb–, 6fvb+, 8fvb–, and 8fvb+). Results from MLP demonstrate exceptional performance, achieving a classification rate of 99.99%. The proposed CEEMDAN-MLP method exhibits robust efficiency, validated by experimental results, and offers promising prospects for BRB fault diagnosis and monitoring in induction motors.
Alternative to laser vibrometers: a non-contact vibration measurement based on enhanced laser speckle pattern and stroboscopic sampling
Authors: Yildiz Ibrahim
Published: February 2025

This research introduces a novel technique for non-contact vibration measurement: the laser speckle stroboscope. Non-contact vibration measurement always yields superior results compared to contact methods as it does not impose any sensor load on the system, making it crucial for sensitive systems. Non-contact measurement techniques are also employed to assess vibrations in extreme temperatures and chemical environments where conventional sensors are prone to damage. This system, built with a laser, lenses, and a photodiode, offers significant improvements in precision compared to traditional stroboscopes. Conventional stroboscopes struggle to accurately measure linear vibrations, while high-precision alternatives like Laser Doppler Vibrometers (LDVs), are expensive. This study attempts to address the limitations associated with laser vibrometers. The laser speckle stroboscope addresses these limitations with a compact and cost-effective design. The system works by creating a laser-generated speckle pattern on the vibrating surface. The pattern is then sampled using a stroboscopic method in which the sampling period is synchronized with the vibration frequency. Rigorous testing confirmed the system’s effectiveness. The focused laser beam precisely captured the rotational movements. For linear vibrations, the system detected deviations as low as 3 Hz for specific frequencies. The rotational measurements showed a maximum deviation of 2 Hz for two out of four tested speeds. These results were validated using an external laser vibrometer, proving the system’s reliability.

Authors: Machado Silvestre Sales , Santos Márcio Achtschin , Menezes João Paulo Calembo Batista , Ferreira Anelisa de Carvalho
Published: February 2025

Objective: The objective of this study is to identify the existing limitations for the adoption of the Internet of Things (IoT) in the management of socio-environmental disaster risks in urban areas.
 
Theoretical Framework: The article examines the importance of using IoT technology in urban territorial management and in the context of socio-environmental risks, in line with the paradigm of resilient cities. The text also establishes a connection between the Internet of Things and Actor-Network Theory, particularly regarding the formation of associative and hybrid processes between human and non-human agents.
 
Method: The methodology adopted for this research includes a qualitative approach and bibliographic study, complemented by secondary and interpretative analysis of documentary data. In a second phase, these documents and regulations were compared with the results of previous research.
 
Results and Discussion: The findings revealed that the challenge or barrier to the effective implementation of this technology in the most vulnerable areas is not only related to budgetary, structural, and regulatory issues but also stems from a deficit in data governance and information and communication technologies suited to each context. Overcoming this obstacle depends on intersectoral planning, as well as the creation of sociotechnical and associative networks, without underestimating the human factor and participation in decision-making.
 
Research Implications: The research is relevant to academic discussions on disruptive technologies and their practical application in urban territorial management.
 
Originality/Value: It addresses a topic still underexplored in the literature and practice of urban and environmental management, despite its applicability in climate change studies and resilient cities.

Authors: Li Dongmei , Cruz Idalia , Sorkhabi Sharareh , Foley Patricia L. , Wagner Julie , Bellanti Joseph A.
Published: February 2025

Background: Allergen immunotherapy (AIT) is the most effective treatment for atopic allergic diseases, aiming to induce regulatory T cells (Treg) that modify the immune response to specific allergens, which leads to long-term tolerance and reduced symptoms. Enhancing Treg
activity is crucial for improving immunotherapy outcomes. In a previous murine model study, we examined the effects of a synthetic methylated DNA oligodeoxynucleotide (ODN) from the Bl-T2 m5C motif of Bifidobacterium longum subsp. infantis. The ODN that contains the methylated
BI-T2 m5C motif (methylated ODNA) sequence conjugated with ovalbumin induced Treg production, whereas ODN that contains the unmethylated BI-T2 m5C motif (unmethylated ODNB) induced proinflammatory responses, which demonstrated the potential of methylated ODNs for AIT. Objective:
In building on these results, this study explored the effects of methylated and nonmethylated DNA motifs from B. longum subsp. infantis on inflammation and Treg induction, while investigating the dose-response relationships of methylated Cytosine-phosphate-Guanine (CpG) ODNs
for optimal Treg stimulation in clinical applications. Methods: Serum levels of IL-17A, IL-4, IL-10, and transforming growth factor beta (TGF-β) were measured by enzyme linked immunosorbent assay (ELISA), and flow cytometry assessed splenic Treg populations in BALB/c
mice receiving graded doses of methylated or unmethylated ODNs. Mice were immunized intraperitoneally with a single 100-μg dose (plan A) or multiple 25 μg (plan B) or 100 μg (plan C) doses. Calf thymic DNA served as a positive control, with phosphate-buffered saline solution and alum
as negative controls. Results: Methylated ODNs significantly increased CD25+FOXP3+ Tregs compared with unmethylated ODNs and controls. Plan A (100 μg) elevated serum IL-10, which indicated effective Treg induction, whereas plan B (four 25 μg
doses) did not activate Tregs. Plan C (multiple 100 μg doses) reduced Treg responses, which highlighted a critical dosing threshold for optimal Treg induction. Conclusion: This study demonstrated the potential of methylated DNA motifs as therapeutic agents in AIT. The
dose-response relationships of methylated CpG ODNs from B. longum pave the way for clinical applications that target Treg activity in allergic diseases.

Science and the Tatshenshini Controversy
Authors: Bell Anne
Published: February 2025

One of the more celebrated conservation success stories in recent Canadian tory was the protection of the British Columbian portion of the Tatshenshini watershed. Plans to mine a copper deposit at Windy Craggy Mountain, near one of the river's tributaries, were brought to an abrupt halt after the provincial government decided to set the area aside as a Class A Provincial Park in June, 1993. The decision was the result of intensive lobbying efforts on the part of groups and individuals who feared the impacts of mining on wildlife and on a place unmarred by roads, dams and industrial development.

Caveat Manipulator
Authors: Fromme Tres
Published: February 2025

Geographic Information Systems (GIS) have, within the last few years, engaged the interests of academics and professionals in the many fields- cartography, geography, computer remote sensing, and among others-at whose intersection GIS emerges. An acknowledged limited survey of the writings and issues indicates that much of the material concentrates on methods, technologies, and applications. The dominant tone of the research and work is positivistic and rareified, as if GIS existed outside of any social situation. Writers enthusiastically concern themselves with data models, (hard/soft)ware issues, and quantifiable results and measures.

Biology as Religion
Authors: Bavington Dean
Published: February 2025

I recently attended a lecture at Acadia University given by a biologist from McGill University who had been sitting on the Canadian panel looking into reproductive technologies. During the lecture, he continually downplayed the risks associated with reproductive technologies and dismissed all critics of the new technology as bio-luddites. It was his belief that many Canadians were afraid of biotechnology because they had not been properly trained in the field. He repeatedly stated the need for early education in genetics for the Canadian population so that they would be better prepared to make decisions around the emerging biotechnologies. He called for "basic genetic principles" to be taught to children in grade four, ensuring that they would grow up with realistic notions of what the technology could accomplish.

Published: February 2025

Simulasi merupakan suatu proses merancang model matematis dari sistem yang nyata dengan cara melakukan percobaan terhadap model menggunakan komputer. Pada penelitian ini simulasi untuk memodelkan kasus perkembangan cashless society karena adanya keterbatasan ketersediaan data asli. Pemodelan simulasi dilakukan berdasarkan hasil analisis data asli yang menggunakan analisis jalur semiparametrik truncated spline. Data asli yang digunakan merupakan hasil kuesioner dengan responden sebanyak 100 nasabah bank pengguna m-banking. Perkembangan cashless society merupakan topik yang menarik untuk diteliti karena di Indonesia sendiri terdapat perubahan kebiasaan masyarakat dalam bertransaksi menggunakan non-tunai semenjak mewabahnya virus COVID-19. Hasil penelitian menunjukkan bahwa skenario model yang dapat dijadikan acuan untuk pengambilan keputusan terkait perkembangan cashless society adalah kombinasi model semiparametrik truncated spline berordo linier dengan dua titik knot di mana hanya terdapat satu hubungan nonparametrik pada model. Hasil penelitian dijadikan acuan oleh pemerintah terkhusus pihak bank untuk mendukung perkembangan cashless society.
 
Abstract
Simulation is a process of designing a mathematical model of a real system by conducting experiments on the model using a computer. In this study, a simulation is used to model the case of the development of a cashless society due to the limited availability of original data. Simulation modeling was carried out based on the results of original data analysis using truncated spline semiparametric  path analysis.The original data used was the result of a questionnaire with respondents of 100 bank customers using m-banking. The development of a cashless society is an interesting topic to study because in Indonesia itself there has been a change in people's habits in transacting using non-cash since the outbreak of the COVID-19 virus. The results show that the model scenario that can be used as a reference for decision-making related to the development  of a cashless society is a combination of a semiparametric truncated spline model of a linear order with two knots where there is only one nonparametric relationship in the model. The results of the research are used as a reference by the government, especially the bank to support the development of a cashless society.

Abstract
Time respone efficiency is key in the implementation of Geographic Information Systems (GIS) across various applications such as navigation, mapping, and location search. This research compares the time respone efficiency of the euclidean, haversine, and manhattan formulas in conducting data searches across different radius variations. The methodology involves the collection and analysis of data generated from implementing these three formulas within a GIS. The data analyzed includes the time taken to complete data search queries across varying radii. Statistical analysis reveals that the manhattan formula achieves a 6.75% increase in time efficiency compared to euclidean, while haversine and euclidean collects 68.8% more data compared to manhattan, showing distinct time respone characteristics dependent on the radius used. It was found that the choice of method depends on the specific priorities of each application. This study provides insights into the advantages and disadvantages of each method in the context of time respone in GIS, offering valuable information for GIS application development, particularly in selecting the most effective distance calculation method according to the specific needs of the application.
