Influence of Multiple Reflows and Surface Finishes on Solder Joint Resistivity
Authors: Dzivy Daniel , Pietrikova Alena , Vrublevskaya Olga , Shikun Marina A.
Published: December 2023

The main purpose of this paper is the analysis of the electrical resistivity of solder joints depending on various surface finishes and on the number of reflow processes. The electrical resistivity was determined after 1, 2, 3, 5 and 6 reflow cycles as a replacement for the basic accelerated aging test. In this article, various surface finishes are compared by measuring electrical resistivity of solder joints between two soldering pads. The influence of standard surface finishes (ENIG, Lead HASL, Lead-free HASL, Cu, ImSn) with the new developed surface finish based on SnAg7 is also compared. Measurements show that the electrical resistivity is dependent on surface finish type and the thickness of the solder joint. The results prove that the new developed surface finish based on SnAg7 is stable against multiple reflows and comparable to the surface finish based on Au. The new developed surface finish based on SnAg7 can be recommended as a replacement for other conventional surface finishes.

Design and Evaluation of a Magnetoelastic Tensile Force Sensor
Authors: Gans Šimon , Molnár Ján
Published: December 2023

This paper introduces the basic theory behind magnetoelastic sensors which are based on the change of magnetic properties (permeability) due to mechanical stress (Villari effect). A well-known magnetoelastic sensor, the Pressductor, is described. A simulation model of a sensor is created, described, and evaluated by computing the static transfer characteristic of RMS secondary coil voltage change due to tensile stress. A real sensor is then manufactured from a polycrystalline transformer sheet and experimentally tested by using a tensile load created by water weight. The simulation and experiment show similar behavior but are not completely identical which is most likely since some material properties were taken from literature rather than from experimental measurements, like the magnetostriction coefficient and initial magnetic susceptibility.
The Influence of Climatic Conditions on the Dynamic Ampacity of Overhead Power Lines
Authors: Beňa Ľubomír , Kolcun Michal , Tailor Rikin
Published: December 2023

The constantly growing demand for electricity demands both on the installed power of energy sources and on the transmission capabilities of electrical networks. Considering the fact that increasing the transmission capabilities of electrical networks by building new lines is a time and financially demanding process, network operators strive to use the transmission capacities of existing lines as much as possible. One of the possibilities of this maximum use of existing capacities is the application of the calculation of the dynamic ampacity of the lines, when the operators of electric networks know how to determine the maximum load capacity of the lines depending on the current climatic conditions. The presented publication presents a methodology for determining the dynamic ampacity of overhead power lines under different climatic conditions with the subsequent application of this methodology to a specific conductor used in the implementation of overhead transmission lines.

Published: December 2023

The global trend of digital transformation is not reserved for those sectors and businesses that are highly dependent on information technology (IT) solutions, but even for those traditional energy companies that still need to pass the long way to maximize green energy, automation and full trajectory of modernizing energy distribution. In energy distribution system Public Enterprise Electric Utility of Bosnia and Herzegovina (PE EP B&H), only around sixteen percent of meters are part of Advanced Metering Management (AMM) system and their data is ready to be used for different data analysis using business intelligence, while data collection from other meters is still done manually, and those one will probably not be replaced as long as they are operable. Main problem that PE EP B&H experienced in digitalization of meter reading data was to overcome readings that meter readers collected and wrote on paper lists.

Based on the reference state, an analysis of energy consumption and energy savings due to the increase in the number of EVs in the future was performed. The main goal of this paper is to provide predictable data on the number of EVs expected in the future, according to models from the EU. These data can be used when planning the development of the network for electric cars, mainly charging stations. An analysis of the current state of the number and locations of charging stations for electric vehicles (EVs) was made.
Aerovalved Pulse Combustor for Enhancing Efficiency and Sustainability of Fossil Energy Conversion
Authors: Smajević Izet , Hanjalić Kemal
Published: December 2023

The paper actualizes earlier research in developing a pulse combustion technique for enhancing the efficacy of utility and industrial boilers and furnaces. Some unpublished results of the experimental investigation of self-sustained pulsating combustion of a gas fuel in an aerovalved pulse combustor (PC) are presented. Relationships have been established between all important design and operating parameters and the combustion characteristics. It was demonstrated that a well-designed pulse combustor can operate efficiently in a stable self-pumping regime in a wide range of operating conditions with the loading from 20% to 100% of the maximum power. While a PC can operate autonomously as a gas burner, the present focus is on their use for mitigating slug and ash deposits on heating surfaces of coal- or biomass fired power and industrial boilers, thus providing an alternative to the proven detonation pulse (DPC) or other techniques for on-line cleaning of heating surfaces during the operation of power and industrial boilers.

Study aim: The aim of the present study was to determine the effect of 8 days of water-only fasting and physical exercise on somatic variables, lipid profile, insulin resistance and cardiovascular function in middle-aged men.

Material and methods: Body weight, body composition, lipid profile, serum concentrations of insulin, glucose, β-hydroxybutyrate (β-HB), heart rate (HR), blood pressure and the homeostasis model assessment of insulin resistance (HOMA-IR) were determined in 16 apparently healthy men at rest and after aerobic exercise. This test procedure was also repeated after 8 days of water-only fasting.

Results: Fasting intervention resulted in a reduction in body weight and fat mass (p < 0.001). The simultaneous effect of fasting and exercise resulted in significant changes in lipid profile, carbohydrate metabolism and cardiovascular function. Post hoc analyses showed that the reductions in insulin and glucose concentrations as well as the HOMA-IR index were caused by the fasting, and changes in the lipid profile and cardiovascular function were caused by the exercise test.

Conclusion: The combined use of fasting and physical effort resulted in an optimal effect on health indicators of the surveyed men.
Mathematical Connection is at the Heart of Mathematical Creativity
Authors: Bicer Ali , Bicer Aysenur , Capraro Mary , Lee Yujin
Published: December 2023

Although teaching mathematics for creativity has been advocated by many researchers, it has not been widely adopted by many teachers because of two reasons: 1) researchers emphasized and investigated mathematical creativity in terms of product dimension by looking at what students have at the end of problem-solving or -posing activities, but they neglected the creative processes students use during mathematics classrooms, and 2) creativity is an abstract construct and it is hard for teachers to interpret what it means for students to be creative in mathematics without further guidance. These can be eliminated by employing techniques of mathematical connections as tools because using mathematical connections can help teachers make sense of how to promote the creative processes of students in mathematics. Because making mathematical connections is a process of linking ideas in mathematics to other ideas and this is a creative act for students to take to achieve creative ideas in mathematics, using the strategies of making mathematical connections has the potential for teachers to understand what it means for students to be creative in mathematics and what it means to teach mathematics for creativity. This paper has two aims to 1) illustrate strategies for making mathematical connections that can also help students’ creative processes in mathematics, and 2) investigate the relationship among general mathematical ability, mathematical creative ability, and mathematical connection ability by reviewing theoretical explanations of these constructs and several predictors (e.g., inductive/deductive ability, quantitative ability) that are important for these constructs. This paper does not only provide examples and techniques of mathematical connection that can be used to foster creative processes of students in mathematics, but also suggests a potential model depicting the relationship among mathematical creativity, mathematical ability, and mathematical connection considering previously suggested theoretical models. It is important to note that the hypothesized model (see Figure 4) suggested in the present paper is not tested through statistical analyses and it is suggested that future research be conducted to show the relationship among the constructs (mathematical connection, mathematical creativity, mathematical ability, and spatial reasoning ability).
Experimental Study on the Mechanical Properties of Green Lightweight Cement Composite Modified by Nano Additives
Authors: Du Yiying , Korjakins Aleksandrs
Published: December 2023

Cement materials have been commonly used in the building and construction industries. However, the process of cement manufacture has long been connected with high consumption of energy and adverse environmental impacts. In this study, in order to produce innovative green cement material that consumes lower energy, resources and is more eco-friendly, industrial waste by-product fly ash cenosphere (FAC) has been utilized as lightweight aggregate to replace cement by 73.3 %. Most research regarding lightweight cement materials with FAC has mainly paid attention to the influence of FAC and the reinforcement via fibre materials, but very few studies have been devoted to the incorporation of nano additives. Therefore, 0.05 %, 0.15 %, 0.45 % of carbon nanotubes (CNTs) and 0.2 %, and 1.0 % of nano silica (NS) were used to modify lightweight cement composite (LWCC). Experiments including flexural strength test, compressive strength test, and thermogravimetric analysis were performed to evaluate the mechanical behaviours and the hydration process of the produced LWCC. Based on the experimental outcomes, incorporating CNTs and NS can effectively contribute to enhancing both flexural and compressive strength, and facilitate cement hydration reaction.
Acquisition of Spanish Temporal Adverbials by Multilingual Estonian Learners
Authors: Mombiela Virginia Rapún , Tramallino Carolina Paola
Published: December 2023

This article focuses on the temporal structures used by multilingual Estonian students when expressing the hour in Spanish. Learning linguistic structures related to time is crucial in the early stages of foreign language acquisition. However, these structures can be complex and vary across languages, as they are highly idiosyncratic in terms of vocabulary and syntax. This study concentrates on the difficulties Estonian students face with Spanish time adverbials, specifically prepositions and articles. The paper aims to answer several research questions related to the repertoire of temporal expressions in the students' interlanguage, the difficulty posed by typological differences between their native language and Spanish, the influence of English, and the impact of English proficiency on Spanish production. The analysis of a corpus of interlanguage texts from Estonian students is conducted to identify idiosyncratic structures and patterns, distinguishing them from standard structures. The findings reveal that the use of articles improves with higher proficiency levels, while the use of prepositions remains challenging. Furthermore, the study explores the influence of English and Estonian on the students' Spanish production and highlights the importance of crosslinguistic reflection and attention to functional words for enhanced accuracy and fluency. The article concludes by emphasizing the significance of language proficiency levels and crosslinguistic influence in third language acquisition and suggesting areas for further research.
Airfoil Tonal Noise Prediction Using Urans
Authors: Klimczyk Witold , Sieradzki Adam
Published: December 2023

To examine the feasibility of the laminar boundary layer (LBL), vortex shedding (VS) tonal noise modelling using unsteady Reynolds-averaged Navier–Stokes (URANS) was investigated for the non-symmetric S834 airfoil. A transition SST turbulence model was used to model the laminar-turbulent transition and its vital influence on the laminar bubble and hydrodynamic instabilities generation. The influence of turbulence on the unsteady vortex patterns was investigated. Hence, the hybrid aeroacoustic analysis with Lighthill analogy was conducted to obtain the acoustic pressure field. The approach allowed us to model hydrodynamic instabilities and the resulting VS tonal noise. The frequency of VS matched the experimental data, giving the same 1/3 octave tonal peak only for a limited freestream turbulence regime. The simplification of the present method did not allow us to model the aeroacoustic feedback loop, and resulted in lack of instabilities for higher freestream turbulence.

Authors: Feronika Feronika , Osawa Takahiro , Merit I Nyoman
Published: December 2023

The Ayung Watershed is one of the watersheds with mountainous and hilly landscapes with potential landslides. This study aims to determine the potential level of landslide susceptibility and its effect on agricultural land use in the Ayung watershed. The method used to determine the potential for landslides is a weighting/scoring method by overlapping the parameters causing landslides, namely rainfall, slope, land use, landform, geological structure, and soil type. Determining the effect of landslide potential on agricultural land is done by overlapping the landslide potential map with land use. The data used includes BMKG monthly rainfall for 2015-2019, the slope of DEMNAS data for 2020, geological structure and landform 1:25,000 scale RBI map data for 2019, land use using Sentinel 2A data for 2020, and soil types in the form of spatial planning maps Province of Bali 1:25,000 scale in 2019. The results showed that landslides in the Ayung watershed were categorized as low potential to high potential. Classes with no landslide potential are widespread in the upstream and downstream areas of the watershed, covering an area of ??18,976.01 ha (60%), the low potential category covering 5,877.78 ha (19%), the medium potential category covering an area of ??3,208.76 ha (10%) and the low potential category covering an area of ??3,208.76 ha (10%) spread over the upstream and central parts of the watershed covering an area of ??3,528.55 ha (11%). The effect of landslides on agricultural land has a category from no potential to high potential. The category with no potential is widespread in the upstream watershed area of ??13,268.57 ha (66%), the low potential category is 3,268.57 ha (16%), the medium potential category is 1,782.31 ha (9%), and the high category is spread in the upstream and the middle of the watershed area of ??1,707.28 ha (9%).

Published: December 2023

Urbanization has an impact on increasing the number of residents in urban areas. This increase has led to increasing problems faced by urban communities such as increased traffic jams, air pollution, employment problems and other problems that tend to cause urban society's aggressiveness and stress to increase. One way to reduce stress is to do activities in open green spaces (RTH). This research was conducted to analyze the quality of open green space in Denpasar City, calculate the stress level of the people in Denpasar City, analyze the relationship between the quality of open green space and the stress level of the people of Denpasar City. This research was conducted by collecting information about the quality of open green space through observation and questionnaires at Sewaka Dharma City Park, Puputan Badung Field (I Gusti Ngurah Made Agung), and Niti Mandala Renon Field. The total number of respondents taken was 210 respondents. The stress value is measured using the perceived stress scale score (PSS-10). The results showed that the community had a moderate stress level with an average PSS score of 20.96. As many as 86% of respondents stated that the open green space in Denpasar was clean, 80% of respondents stated that the air quality in open green space was cool, 56% of respondents stated that the placement of vegetation was comfortable, 41% of respondents stated that the smell of waste in open green space was not disturbing, and 60% of respondents stated that the conditions of the facilities in open green space were good. The quality of open green space has a real relationship to the stress level of the people of Denpasar City (p value = 0.037). This research is expected to provide information to the government and the public regarding the use and maintenance of city parks.

RETRIEVAL OF SURFACE CURRENT FROM HIMAWARI-8 SEA SURFACE TEMPERATURE DATA AND PARTICLE IMAGE VELOCIMETRY METHOD
Authors: Wati Kadek Setiya , Osawa Takahiro , Astawa Karang I Wayan Gede
Published: December 2023

As human activity occurs at the surface, which is influenced by surface currents, understanding surface currents is crucial. Ocean currents are not solely caused by wind, but also of other factors, such as sea surface temperature. To obtain surface current data, BMKG used HF radar installed in several places, including Flores Sea. This location is significant because it has large ports and heavy crossing traffic. This study aims to analyse surface current data retrieve from Himawari-8 SST data by applied PIV algorithm. Using the PIV algorithm, a cross-correlation plane is generated by comparing two identically sized interrogation windows obtained from successive images. On 5 December 2022 in the Flores Sea, Himawari-8 SST data was employed to estimate sea surface currents every 10 minutes. Surface current motion varies widely from image to image. Western areas are dominated by westward currents, while central and eastern areas are dominated by eastward currents during daylight hours, and westward currents during the night. Synoptic wind affects surface current movement during those hours. Validation with observational data from the Labuan Bajo HF radar shows that the V component current estimation is better than the U component current estimation. This is particularly prevalent in the south and in areas close to the KAWA radar HF location.

OIL SPILL SIMULATION IN THE BALI STRAIT USING THE GNOME AND FVCOM MODELS ON EASTERLY SEASON
Authors: Putu Hadi Wiguna Pande , Hendrawan I Gede , Osawa Takahiro
Published: December 2023

Among several forms of marine pollution, oil damages coastal ecosystems. Repeated reports of oil contamination in the marine environment can partly load with major shipping lines. The Ketapang-Gilimanuk crossing over the Bali Strait is Indonesia's second busiest ferry port after Merak-Bakauheni. The most congested shipping routes can carry a significant risk of environmental damage from an oil spill. Oil spill trajectory modelling is carried out to reduce the impact of this possible disaster. Therefore, the use of modelling to ascertain the route of the oil spill was considered. The oil leak path is simulated using the GNOME model. Two oil spill scenarios were used as input models. The chosen location is around the Ketapang Gilimanuk crossing, as well as the time of the easterly season. An ocean HF radar stationed in the Bali Strait verifies the accuracy of the current marine data generated by FVCOM. To see the pattern of the oil spill trajectory based on a ten days simulation, we combined the latest data from FVCOM with GNOME. To determine the ability of the model to predict the flow and trajectory of oil spills in the Bali Strait, this study try to analyze and interpret the oil spill trajectory from model and then validate the model results with satellite imagery.

Blooms of Raphidiopsis raciborskii (Woloszynska) Aguilera & AL. 2018 in Semiarid Reservoirs: An Approach Integrated Bayesian
Authors: Nery Janiele França , Nery Gleydson Kleyton Moura , Ferreira Weruska Brasileiro , Da Costa Batista Fabiane Rabelo
Published: December 2023

Objective: This study aims to determine which environmental factors are the most important in explaining the variation in the abundance of Raphidiopsis raciborskii in semi-arid reservoirs using Bayesian networks.
 
Method/design/approach: To compile the database, a search for articles was carried out on the Scielo and Scopus platforms. Only articles that reported the occurrence of R. raciborskii were considered. After reading, 3 works were selected, which presented values of water transparency (m), water temperature (ºC), pH, electrical conductivity (µS/cm), dissolved oxygen (mg/L), ammonium concentrations (µg/ L), SRP (reactive soluble phosphorus) (µg/L), total phosphorus (µg/L), cyanobacterial density (cel/mL) and Raphidiopsis raciborskii (cel/L). Using these data, a Bayesian network was built to analyze the sensitivity of bloom development to different environmental factors, considering three risk categories (low, medium and high) based on cell abundance.
 
Results and conclusion: Water transparency and reservoir volume were the most important variables for predicting blooms in semiarid systems. Regardless of the storage capacity of the reservoirs and complexity of interactions between the variables, the proposed Bayesian network proved to be a useful tool for: exploring the interactions between volume oscillation in reservoirs with nutrients and temperature simultaneously. thus constituting a potential tool for management and management of water resources in the semi-arid region.
 
Research implications: The Bayseian network constitutes a potential tool for the management of water resources in the semi-arid region.
 
Originality/Value: The originality of this research resides in the proposed use of Bayesian networks as a predictability tool for the management of water resources in the treatment of cyanobacterial blooms, especially for the cosmopolitan and highly resistant species R. raciborskii.

Solution Algorithm for the Routing Problem in Capacitated and Periodic Arcs Applied to Hydroelectric Plant Monitoring
Authors: Da Silva Fausto Pinheiro , Wilhelm Volmir Eugenio , Sandmann André
Published: December 2023

Objective: The present work presents a linear model capable of optimizing the routes that a reader takes to make measurements of the auscultation instruments installed in a hydroelectric plant.
 
Theoretical framework: Tirkolaee's work was a reference for solving the problem of determining the best routes, serving as one of the bases of this work, as in this article, in addition to being concerned with solving the PCARP, we sought to minimize the number of vehicles needed to carry out the task. But he doesn't work with a predefined frequency like in Chu or with multiple tasks like in Cleverson. Since Cleverson is a generalization of Chu's work, as the edge has different demands, that is, different tasks. These tasks would be reading the auscultation instruments, that is, reading the Thermometer, Pendulum, Seismograph and Piezometer. But it differs from this, as it does not aim to reduce the number of vehicles.
 
Method: Develop a model that can take into consideration the following characteristics: one must choose which of the combinations of days of the week will be used to perform each of the reader's tasks; determine which of the readers will read route y that contains gallery x and which instruments will be read; the reader will necessarily have to pass once performing the task, however he may have to pass the edge without performing any task to maintain the continuous flow; readers may not be qualified to perform all tasks, as they do not have knowledge of how to use the device that reads a given instrument; the reader will have to leave the deposit, which is represented by the vertex “0” and return to it at the end of the day; the time to travel the path to the warehouse, take instrument readings and return to it cannot exceed the reading worker's working hours per day;
 
Results and conclusion: The result points to an improvement of 81% in relation to the reduction in distances covered by vehicles in all instances tested using AS, in 76% of instances tested with AS the solution without subcycle was achieved in less time, as well as a decrease in number of vehicles needed to meet the same demands of 66% when we analyze the maximum number of vehicles used in a day and 66% when we add the total number of vehicles used in the period.
 
Implications of the research: Model that can be applied both in determining the best route for the reader and in other real situations, such as analyzing equipment measurement routes within an industry and in garbage collection.
 
Originality/value: The Solution Algorithm, in addition to the linear model, brings originality to its construction and compilation, as the algorithm constitutes a way to find a feasible solution. With the solution algorithm it is possible to find a feasible solution that determines the shortest distance and together with the smallest number of surveyors needed to carry out the work, which ends up taking less time to carry out all inspections.

Reworking the Brochure of Radya Pustaka Museum Surakarta: The Rhetorical One to Attract Locals
Authors: Khrisna Dyah Ayu Nila , Budiharjo Bayu , Dewi Ida Kusuma
Published: December 2023

Background:

Increasing touristsâ€™ interest to visit museums can be accomplished through various promotional strategies. However, the Radya Pustaka Museum brochure falls short of successfully informing potential visitors about the museum's potency.

Methodology:

The brochure of Radya Pustaka Museum was first studied. Four locals were asked to review the brochure for naturalness and clarity. An open questionnaire was used, in which the respondents marked the expressions they perceived were unnatural or difficult to comprehend. In using content analysis, the primary data were gathered from the Indonesian descriptive texts in the brochure.

Findings:

Some of the information in the previous brochure of the Radya Pustaka museum was vague and confusing. Grammar mistakes, the frequent use of local cultural words, and overly complex sentences are all factors that contribute to this problem. To begin, all the grammatical errors and typos must be fixed. The museum's name should no longer be miswritten. Capitalization should also be considered when writing names and address forms. Additionally, each sentence must start with a subject.

Conclusion:

The proposed new concept brochure of the Radya Pustaka Museum in Surakarta is projected to increase the locals' interest in having a museum that they are eager to visit. The Appraisal theory was discovered to be useful in assisting the museum with these efforts because it is conceptually similar to rhetorical devices that effectively produce a promotional medium or message to engage the locals in embracing the museum.

Originality:

This study attempts to get the picture of the link between rhetorical strategies and Appraisal resources, as never been previously done, and make the best use of them to attract localsâ€™ desire in visiting Radya Pustaka Museum. Due to the small number of studies looking into rhetorical tactics in brochures, this research also intends to fill the gap to shed more light on how the strategies can serve as valuable resources in making intended effects more impactful in communication using brochures.
Family Surveillance: Understanding Parental Monitoring, Reciprocal Practices, and Digital Resilience
Authors: Mols Anouk , Pereira Campos Jorge , Pridmore Jason
Published: December 2023

Parents who grew up without digital monitoring have a plethora of parental monitoring opportunities at their disposal. While they can engage in surveillance practices to safeguard their children, they also have to balance freedom against control. This research is based on in-depth interviews with eleven early adolescents and eleven parents to investigate everyday negotiations of parental monitoring. Parental monitoring is presented as a form of lateral surveillance because it entails parents engaging in surveillance practices to monitor their children. The results indicate that some parents are motivated to use digital monitoring tools to safeguard and guide their children, while others refrain from surveillance practices to prioritise freedom and trust. The most common forms of surveillance are location tracking and the monitoring of digital behaviour and screen time. Moreover, we provide unique insights into the use of student tracking systems as an impactful form of control. Early adolescents negotiate these parental monitoring practices, with responses ranging from acceptance to active forms of resistance. Some children also monitor their parents, showcasing a reciprocal form of lateral surveillance. In all families, monitoring practices are negotiated in open conversations that also foster digital resilience. This study shows that the concepts of parental monitoring and lateral surveillance fall short in grasping the reciprocal character of monitoring and the power dynamics in parent-child relations. We therefore propose that monitoring practices in families can best be understood as family surveillance, providing a novel concept to understand how surveillance is embedded in contemporary media practices among interconnected family members.
Costs, Inconvenience, or Civil Rights? Investigating Determinants of Public Support for Surveillance
Authors: Antoine Lukas
Published: December 2023

As a response to security threats, governments around the globe, albeit in different magnitude, have implemented measures of mass surveillance interfering with individual rights. Regardless of prominent (normative) debates on surveillance and security, studies examining individual attitudes and factors explaining them are relatively scarce. While people in general prefer living in a secure environment, I argue that it is not only the imminent trade-off between security concerns and protecting one’s privacy and freedom that ultimately persuades citizens to support surveillance measures.

Musculoskeletal disorders pose a substantial health risk to employees in various professions worldwide, particularly those in healthcare settings. While prior research has predominantly focused on musculoskeletal issues among nurses, limited attention has been given to doctors across different specialties, including surgeons. Surgeons face unique challenges, combining intense mental focus, precision in movements, and varying physical demands. This systematic review aimed to explore the epidemiology, causes, and management of musculoskeletal disorders among surgeons and healthcare workers. PubMed/Medline and Embase were used as data sources, and articles published in English from 2010 to 2023 were reviewed following PRISMA guidelines. The analysis included seven articles, primarily employing surveys and national database analyses. The findings revealed a high prevalence of musculoskeletal symptoms among healthcare workers, particularly surgeons, who experienced significant rates of shoulder, back, and neck complaints. Physical risk factors, including constrained postures and repetitive motions, were identified as significant predictors of musculoskeletal problems. Holistic treatment approaches that consider the patient\'s lifestyle, preferences, mental health, and concurrent conditions were emphasized. Conservative therapy, assistive technology, psychiatric counseling, and coping skills were recognized as beneficial interventions. The study underscores the importance of understanding and managing musculoskeletal disorders in healthcare workers, contributing to improved evaluation and management strategies in the future. Surgeons, in particular, require attention to their unique work.
