Investigating the determinants of ecological and carbon footprints. Evidence from high-income countries
Authors: Yousaf Hazrat , Amin Azka , Ameer Waqar , Akbar Muhammad
Published: July 2022

High-income countries have experienced rapid economic growth, urbanization, consumption of renewable and non-renewable energy, increased trade dependency, and the attainment and maintenance of higher living standards over the last four decades, while also experiencing an increasing trend in environmental degradation. These experiences have fueled our desire to learn more about the factors that influence the ecological footprint and carbon footprint of high-income countries. The purpose of the present study is to investigate the effects of natural resources, urbanization, GDP per capita, population, and fossil fuels on ecological and carbon footprint for 34 high-income countries over the period 2003–2015. Using the STIRPAT model, the results confirm the environmental Kuznets curve hypothesis in the case of total ecological footprint while the link between economic growth and carbon footprint is in U-shape. In terms of total ecological footprint determinants, population reduction as well as efficient urban design, are viable solutions. The findings support the positive and statistically significant influence of population, urbanization, and fossil fuels on total ecological footprint, as well as the negative impact of ecological efficiency. The findings of the carbon footprint suggest that reduction in coal and oil consumption, as well as increasing the use of gas as a source of energy, are all viable choices to mitigate carbon footprint. Furthermore, increasing ecological efficiency could be a viable policy option for reducing high-income countries' footprints.
Blowup and MLUH stability of time-space fractional reaction-diffusion equations
Authors: Gao Peng , Chen Pengyu
Published: July 2022

In this paper, we consider a class of nonlinear time-space fractional reaction-diffusion equations by transforming the time-space fractional reaction-diffusion equations into an abstract evolution equations in a fractional Sobolev space. Based on operator semigroup theory, the local uniqueness of mild solutions to the reaction-diffusion equations is obtained under the assumption that nonlinear function is locally Lipschitz continuous. On this basis, a blowup alternative result for unique saturated mild solutions is obtained. We further verify the Mittag-Leffler-Ulam-Hyers stability of the nonlinear time-space fractional reaction-diffusion equations.

Published: July 2022

Ultrahigh molecular weight polyethene (UHMWPE) is employed as a bearing material in a range of applications due to its improved elasticity, compatibility, and impact resistance, processing conditions for a suitable surface texture are necessary. Surface texture processing on microchannels using lasers is always associated with the effect of heat damage on the polymer specimen surface. This study aims to explore the use of polydimethylsiloxane (PDMS) and polyacrylic acid (PAA) in the form of liquid gel coatings in order to reduce heat damage to surfaces during the laser processing of ultrahigh molecular weight polyethene (UHMWPE). First, PDMS and PAA were coated on the surface of the UHMWPE material specimen, and then texturing was performed using a laser diode and cleaned using the ultrasonic method. Second, the dimensions and texture profiles of all the samples from this study were measured using a confocal microscope and open source software. In addition, the effect of adding liquid gel on the surface at 150 µm thickness and laser power parameters was determined. The results show that the PDMS and PAA liquid gel layers help regulate the dimensional bulge of the fabricated microchannels at laser powers below 6 watts, compared to those produced without the coating.
A novel analytical Aboodh residual power series method for solving linear and nonlinear time-fractional partial differential equations with variable coefficients
Authors: Liaqat Muhammad Imran , Etemad Sina , Rezapour Shahram , Park Choonkil
Published: July 2022

The goal of this research is to develop a novel analytic technique for obtaining the approximate and exact solutions of the Caputo time-fractional partial differential equations (PDEs) with variable coefficients. We call this technique as the Aboodh residual power series method (ARPSM), because it apply the Aboodh transform along with the residual power series method (RPSM). It is based on a new version of Taylor's series that generates a convergent series as a solution. Establishing the coefficients for a series, like the RPSM, necessitates the computation of the fractional derivatives each time. As ARPSM just requires the idea of an infinite limit, we simply need a few computations to get the coefficients. This technique solves nonlinear problems without the He's polynomials and Adomian polynomials, so the small size of computation of this technique is the strength of the scheme, which is an advantage over the homotopy perturbation method and the Adomian decomposition method. The absolute and relative errors of five linear and non-linear problems are numerically examined to determine the efficacy and accuracy of ARPSM for time-fractional PDEs with variable coefficients. In addition, numerical results are also compared with other methods such as the RPSM and the natural transform decomposition method (NTDM). Some graphs are also plotted for various values of fractional orders. The results show that our technique is easy to use, accurate, and effective. Mathematica software is used to calculate the numerical and symbolic quantities in the paper.

Published: July 2022

Under investigation in this paper is a reaction-diffusion system, which describes acid-mediated tumor growth. First, in view of Lie group analysis, infinitesimal generators of the considered system are presented. At the same time, some group invariant solutions are computed using reduced equations. In particular, we construct explicit solutions by applying the power-series method. Furthermore, the convergence of the solutions of the power-series is certificated. Finally, the stability behavior of the model can be understood by analyzing the solutions of different parameters.

Published: July 2022

Glucose management for people with type 2 diabetes mellitus is essential but challenging due to the multi-factored and chronic disease nature of diabetes. To control glucose levels in a safe range and lessen abnormal glucose variability efficiently and economically, an intelligent prediction of glucose is demanding. A glucose trajectory prediction system based on subcutaneous interstitial continuous glucose monitoring data and deep learning models for ensuing glucose trajectory was constructed, followed by the application of personalised prediction models on one participant with type 2 diabetes in a community. The predictive accuracy was then assessed by RMSE (root mean square error) using blood glucose data. Changes in glycaemic parameters of the participant before and after model intervention were also compared to examine the efficacy of this intelligence-aided health care. Individual Recurrent Neural Network model was developed on glucose data, with an average daily RMSE of 1.59 mmol/L in the application segment. In terms of the glucose variation, the mean glucose decreased by 0.66 mmol/L, and HBGI dropped from 12.99 × 102 to 9.17 × 102. However, the participant also had increased stress, especially in eating and social support. Our research presented a personalised care system for people with diabetes based on deep learning. The intelligence-aided health management system is promising to enhance the outcome of diabetic patients, but further research is also necessary to decrease stress in the intelligence-aided health management and investigate the stress impacts on diabetic patients.
An Integrated Intelligent Computation for Complex Problems in Engineering Management
Authors: Sheibani Kaveh
Published: July 2022

In recent years there has been a growth of interest in the development of systematic search methods for solving problems in operational research and artificial intelligence. This chapter introduces a new idea for the integration of approaches for hard combinatorial optimisation problems. The proposed methodology evaluates objects in a way that combines fuzzy reasoning with a greedy mechanism. In other words, a fuzzy solution space is exploited using greedy methods. This seems to be superior to the standard greedy version. The chapter consists of two main parts. The first part focuses on description of the theory and mathematics of the so-called fuzzy greedy evaluation concept. The second part demonstrates through computational experiments the effectiveness and efficiency of the proposed method for a number of complex problems in engineering management and beyond.

Published: July 2022

Increased agricultural activity is intended as intelligent agriculture or precision agriculture to be of critical importance. The fast growth of networking has resulted in IoT-based farm management systems. Increased agricultural activity is intended as intelligent agriculture or precision agriculture to be of critical importance. The established cloud-based platforms cannot cope with the huge quotas and diverse data provided by the connected IoT devices, which are based on conventional cloud models. It is important to get data processing closer to the origins of their output to reduce lag in aiding real-time decision-making based on the data generated. The adoption of fog-based models will solve this and will be discussed in this chapter. To ensure optimum bandwidth usage and low latency for real-time decision-making, an IoT-Fog farm management system may be more capable.
The Main Principles of Democracy and Its Role in Global Development
Authors: Chitadze Nika
Published: July 2022

Democracy is a political system based on the method of collective decision-making with the equal influence of participants on the outcome of the processor at its essential stages. Although this method is applicable to any social institution, today its most important application is the state, since it has a lot of power. In this case, the definition of democracy is usually narrowed down to one of the following: 1) The appointment of leaders by the people they govern is through fair and competitive elections. 2) The people are the only legitimate source of power. 3) Society exercises self-government for the common good and the satisfaction of common interests. People's government requires the provision of a number of rights for each member of society. A number of values are associated with modern democracy: legality, political and social equality, freedom, the right to self-determination, human rights, etc.
The Democratic Political Regime and Its Role in State Development
Authors: Kervalishvili Irakli
Published: July 2022

Political regime (fr. régime from lat. regimen – management, command, leadership) is a set of means and methods by which political power is exercised in the state. The political regime characterizes the models of appointing persons to managerial positions, exercising and transferring power, the role of violence in the political process, as well as the activities of political subjects: the level of political competition, the degree of closeness of political elites, the degree of participation of citizens in governance, institutional restrictions imposed on actors. Sometimes the concept of a political regime also includes the degree of political freedom in society and the observance of human rights. In the case of democracy, the following issues represent the main characteristics of a democratic political regime: 1) The appointment of leaders by the people they govern takes place through fair and competitive elections. 2) The people are the only legitimate source of power. 3) The society exercises self-government for the common good and satisfaction of common interests.

Published: July 2022

This chapter discusses pre-service teachers' views about the United Nations (UN) Convention on the Rights of the Child and how teachers perceive their connection to the educational context and their work. The authors argue that pre-service teachers' perceptions determine how successfully human rights education is implemented in practice. The data were collected from workshops and focus group discussions conducted with 82 primary school pre-service teachers in Northern Finland. The participants noted that children's rights are important and deeply connected to their work. However, they were insufficiently familiar with HRE concepts, and they were uncertain about whether it was acceptable to physically restrain children to protect them or others, as this could undermine a child's rights. To adhere to the principles in the UN Convention on the Rights of the Child, the topic must be included in the pre-service study syllabus, more clearly added to the curriculum, and implemented in teacher practice.
Rule of Law as a Basis for the Establishment of a Constitutional State
Authors: Kervalishvili Irakli
Published: July 2022

The term rule of law is closely related to both constitutionalism and the rule of law, and it refers to the political situation and not to any particular legal law. According to the rule of law, all people are subject to the law, including legislators, law enforcement, and judges. In this sense, it opposes tyranny or oligarchy, where rulers stand above the law. Lack of the rule of law can be found in both democracies and monarchies where laws are not taken into account. The rule of law is at stake where the government does not have the appropriate corrective mechanism to restore it.

Authors: Johnson Austin Saundra , Dickerson Darryl , Freeman Amy , Ainsworth Enrique (Rick) , Booth Womack Virginia
Published: July 2022

This chapter presents a comprehensive 50-year history of diversity in STEM interventions and lessons learned from diversity professionals in institutional university settings. Recommendations include developing professional identity, communities of practice, and formal credentialing of this specific skill set. Colleges of engineering have been leaders in the creation of effective STEM interventions, commonly called multicultural engineering programs (MEPs), with a focus on the graduation of African American, Hispanic, American Indians, and Alaska Native students. America's history sparked a movement of the adoption and the implementation of MEP offices at predominantly White institutions (PWIs). Institutionalizing such programs and activities became a challenge for MEP administrators over the years, which led to the forming of the National Association of Multicultural Engineering Program Advocates, Inc. (NAMEPA). This leading professional organization serves as a repository of best practices learned through the transferable MEP model to broaden the participation in all STEM fields.

The Digital Transformation of Education Amidst COVID-19
Authors: Currey Robert , George Babu
Published: July 2022

COVID-19 is a major inflection point in the civilizational development of the contemporary society as it passes through various phases of industrial revolutions. Pre-COVID-19, the technological realm was ready to trigger a major disruption, but the societal realm was putting pauses upon it. The wrath and fury that ensued as COVID-19 became a global pandemic in the span of a few months meant that there was no choice but to embrace the digital in all its ramifications. Certain industries underwent this transformation organically, albeit quickly. This chapter attempts to portray the digital transformation of education just before and during COVID-19 and then goes on to discuss how the cultural shift into the digital-dominant, post-COVID-19 world could lead to disruption in the educational industry, potentially displacing “old school” models with new technologies and practices.
Temporal Variation of Collaboration in a Collaborative Environment
Authors: Barhoun Rabie
Published: July 2022

In recent years, collaborative environments play a significant role in collaboration work. The keys element of these environments is the process of collaboration. The calculation of the collaboration does not depend on the current collaboration but also on the past-time collaboration value. The value of collaboration is affected by time-invariant factors, as well as time. The time factor is a crucial element in determining the value of collaboration. This chapter discusses the effect of time on collaboration value, which influences the variation over time of the level of reliability of a collaborative environment. The proposal is based on the ability to measure the temporal variation of the reliability of a collaborative environment. Existing collaborative environments do not take this measurement time into account to determine the level of reliability of the collaboration. The simulations show that the approach offers more flexibility in interpreting the decay of collaboration over time.
An Empirical Analysis of Code Smelling and Code Restructuring in Python
Authors: Vashisht Rohit
Published: July 2022

Code smellings are not bugs or errors; rather, they are a fundamental deviation in software design that lowers code quality. Code smells don't always mean the software won't work; it will still provide a result, but it can slow down processing, increase the risk of failure and errors, and make the programme more vulnerable to future flaws. The conceptual theory behind code smell and its various kinds are discussed in this chapter. Identifying and eradicating code smells is a time-consuming and endless process with no guarantee that the software will be smell-free. Also, because it's very hard to uncover and eliminate all smells by hand, adopting automated code review techniques that can detect smells becomes essential. Code refactoring is one method of restructuring written code to reduce the effects of bad code smell on generated software code. A novel three-phase code refactoring framework has been proposed in this study. The effectiveness of Python code smell detection using Pysmell tool and refactoring using the rope automation tool are also studied in this chapter.
Carpooling Solutions Using Machine Learning Tools
Authors: Pramanik Sabyasachi
Published: July 2022

If there isn't enough parking within a university's campus, it will take a long time to look for parking. If a university has a number of research stations that are geographically apart from one another, communication occurs between them and the main office using office cars, although occasionally leased vehicles are obtained from a travel agency. The cost of transportation will rise as a result. Similarly, all students who are not from the dormitory are day scholars who come from their homes. Every day they must drive a significant distance to go to the institution in rented automobiles. This chapter deals with the performance solutions in carpooling using machine learning techniques.

Authors: Millan-Guerrero Horacio Alain , Nuñez-Lopez Jose Antonio , Murrieta-Rico Fabian N. , Lindner Lars , Sergiyenko Oleg , Rodríguez-Quiñonez Julio C , Flores-Fuentes Wendy
Published: July 2022

In this chapter, the authors design, simulate, and implement an optimal controller for a rotary pendulum while addressing real-world phenomena. The controller, called linear-quadratic-regulator (LQR), minimizes a cost function based on weights that penalize the system's state error and controller effort. The control objective is to reach the desired system state in an optimal way. The rotary pendulum consists of a pendulum attached to a rotary arm actuated by a motor. It is a great system to design and analyze different types of controllers. This system is underactuated, nonlinear, sensitive to initial conditions, and has 2 DOF. This chapter's main contributions are the mathematical modeling of the system taking into account nonlinear friction, the characterization of the plant using measured data from the physical system using the nonlinear squares and the trust-region reflective algorithms, comparison of linear and nonlinear behaviors, and implementation on real hardware considering discrete phenomena while using hardware-provided tools such as position decoding and PWM generation.
Implementation and Analysis of Different POS Tagger in Khasi Language
Authors: Hynniewta Risanlang , Maji Arnab K. , Warjri Sunita
Published: July 2022

Part-of-speech tagging is a process of assigning each word of a sentence to a part of speech based on its context and definition. POS tagging is a prerequisite tool for many NLP tasks like word sense disambiguity, name entity information extraction, etc. Unfortunately, very little work has been done so far in this line for Khasi Language. The main difficulty lies with the unavailability of an annotated corpus. Hence, a small corpus is created which consists of 778 sentences with 34,873 words, out of which 3,942 are distinct words and a tagset of 52 tags. In this chapter, three methods for POS tagging, namely Brill's tagger, hidden Markov model (HMM)-based tagger, and bidirectional long short-term memory recurrent neural network (Bi-LSTM), have been implemented. Then a comparative analysis is performed, and it is observed that Bi-LSTM performs better in terms of accuracy.

The analysis of environmental DNA (eDNA) by high throughput sequencing (HTS) is proving to be a promising tool for freshwater fish biodiversity assessment in Europe within the Water Framework Directive (WFD, 2000/60/EC), especially for large rivers and lakes where current fish monitoring techniques have known shortcomings. These new biomonitoring methods based on eDNA show several advantages compared to classical morphological methods. The sampling procedures are easier and cheaper and eDNA metabarcoding is non-invasive and very sensitive, allowing for the detection of traces of DNA. However, eDNA metabarcoding methods need careful standardization to make the results of different surveys comparable. The aim of the EU project Eco-AlpsWater is to test and validate molecular biodiversity monitoring tools for aquatic ecosystems (i.e., eDNA metabarcoding) to improve the traditional WFD monitoring approaches in Alpine waterbodies. To this end, an inter-calibration test was performed using fish mock community samples containing either tissue-extracted DNA, eDNA collected from aquaculture tanks and eDNA samples collected from Lake Bourget (France). Samples were analysed using a DNA metabarcoding approach, relying on the amplification and HTS of a 12S rDNA marker, in two separate laboratories, to evaluate if different laboratory and bioinformatic protocols can provide a reliable and comparable description of the fish communities in both mock and natural samples. Our results highlight good replicability of the molecular laboratory protocols for HTS and good amplification success of selected primers, providing essential information concerning the taxonomic resolution of the 12S mitochondrial marker in describing the Alpine fish communities. Interestingly, different concentrations of species DNA in the mock samples were well represented by the relative DNA reads abundance. These tests confirm the reproducibility of eDNA metabarcoding analyses for the biomonitoring of freshwater fish inhabiting Alpine and peri-Alpine lakes and rivers.

Multiple factors control the growth of a child, including genetics, nutrition, and socioeconomic factors. Referral of tallboys who are otherwise well is very rare. However, sometimes, extraordinary tall stature for the age can be a cause of great concern to the parents. We report a case of an Omani child with a de novo mutation of NSD1 that led to his overgrowth and diagnosis of Sotos syndrome (SoS). This syndrome is a rare genetic disorder. Only two cases of genetically proven diagnosis were reported from the Middle East and North Africa region. Therefore, we describe a case and highlight the comorbidities associated with this condition, encouraging colleagues from the region to report their cases to understand better the phenotype–genotype and the natural history of this disorder in this part of the world.
Low‐clock‐speed time‐interleaved architecture for a polar delta–sigma modulator transmitter
Authors: Erfani Majd Nasser , Fani Rezvan
Published: July 2022

The polar delta–sigma modulator (DSM) transmitter architecture exhibits good coding efficiency and can be used for software‐defined radio applications. However, the necessity of high clock speed is one of the major drawbacks of using this transmitter architecture. This study proposes a low‐complexity time‐interleaved architecture for the polar DSM transmitter baseband part to reduce the clock speed requirement of the polar DSM transmitter using an upsampling technique. Simulations show that using the proposed four‐branch time‐interleaved polar DSM transmitter baseband part, the clock speed requirement of the transmitter is reduced by four times without degrading the signal‐to‐noise‐and‐distortion ratio.

This paper presents a new concept of a photovoltaic module. The increase in efficiency is obtained by using a three-dimensional form of flexible photovoltaic panels with an additional reflecting mirror. A flexible panel is distributed over the entire inner surface of the cylinder, while the mirror distributes the flux on its surface. The comparison of selected solutions for a mirror shape is realized with numerical simulations. The irradiance results for absorbed flux are discussed on the ground of possible improvements.

Efficient removal of methyl orange using magnesium oxide nanoparticles loaded onto activated carbon
Authors: Venkata Ratnam M. , Vangalapati Meena , Nagamalleswara Rao K. , Ramesh Chandra K.
Published: July 2022

ABSTRACT. In this work, an activated carbon composite made with magnesium oxide nanoparticles (MgONP-AC) was effectively utilized for methyl orange (MO) adsorption. The effect of pH (6-10), mass of MgONP-AC (0.1-0.3 g/L), initial MO concentration (10-30 mg/L), and temperature (283-323 K) on MO removal was investigated using a central rotatable composite experimental design based on the response surface technique (RSM) at an equilibrium agitation period of 60 min. The studies predicted the optimal MO removal of 98.99% at pH 7.68, MgONP-AC dosage of 0.24 g/L, and starting MO concentration of 15 mg/L, and temperature of 313 K. Furthermore, an artificial neural network (ANN) was utilized to simulate MO adsorption, and it properly predicted MO removal using mean squared error (MSE) and R2 for the testing data. The ANN predicts a maximum removal of 99.63% with ANN with R2 = 0.9926. The kinetic results suited the pseudo-second order kinetic equation, and the data from the equilibrium investigations corresponded well with the Langmuir isotherm (maximum uptake capacity qmax = 346 mg/g). Endothermic, spontaneous, and physical adsorption were discovered during the thermodynamic investigations.

Published: July 2022

Este artigo buscou analisar a Corrida Orientada e suas intersecções didáticas para auxiliar na interpretação e compreensão da linguagem cartográfica dos estudantes da escola básica. Desviando de binarismos impostos à Cartografia Escolar, marcada por uma espacialidade cartesiana, que entende o mapa como “representação da realidade”, optamos por uma abordagem pós-estrutural, notadamente pós-representacional que procura situar as experiências de estudantes (mapeadores) do ensino médio de uma escola parceira do subprojeto de Geografia do Programa Institucional de Bolsas de Iniciação à Docência (PIBID)  da Universidade Estadual de Feira de Santana (UEFS), como parte do processo de mapeamento, e o mapa como uma dimensão aberta, produto da compreensão e interpretação das experiências espaciais e sua interação semiótica, observados a partir dos acontecimentos forjados por negociações e intencionalidades espaciais diversas, expressos na dinâmica relacional de cada mapeador e seus pensamentos e imaginações espaciais.

INTERSECTIONS OF AN ORIENTED RACE IN THE (RE)CONSTRUCTION OF CARTOGRAPHIC KNOWLEDGE
Abstract
This article sought to analyze the Oriented Run and its didactic intersections to help in the interpretation and understanding of the cartographic language of two elementary school students. Deviating from the imposed binarisms of School Cartography, marked by a Cartesian spatiality, which understands the map as "representation of reality", we opted for a post-structural approach, markedly post-representational, that seeks to situate the experiences of students (mappers) of middle school of a partner school of the Geography subproject of the Institutional Program of Teaching Initiation Exchanges (PIBID) of the State University of Feira de Santana (UEFS), as part of the mapping process, and the map as an open dimension, product of understanding and interpretation the spatial experiences and their semiotic interaction, observed from two events forged by negotiations and diverse spatial intentions, expressed in the relational dynamics of each mapper and their spatial thoughts and imaginations.

Production and Feeding Patterns of Cattle in Manipur- Findings from Small Farmers
Authors: Singh Oinam Krishnadas
Published: July 2022

The purpose of this study was to examine the production and feeding patterns of cattle among the small farmers in the Thoubal district of Manipur. The findings revealed that, on average crossbred and local cow dairy farms maintained 1.60 and 1.25 milch animals, respectively. The investment percentage was found to be highest on milch animals followed by cattle shed and equipment for both the category of farm households which were ` 80756.82 for crossbred and ` 21506.75 for local cow, and the overall investment was ` 102263.57. On average milking crossbred cow was fed with 11.33 kg/day of dry fodder, 17.06 kg/day of green fodder, and 3.23 kg/day of concentrates, and for the local cow, it was 5.82 kg/day of dry fodder, 7.25 kg/day of green fodder, and 1.75 kg/day of concentrates, respectively. The average yield per crossbred cow was 9.50 liters/day, and that of the local cow was 1.60 liters/day. It can be concluded that training facilities by veterinary and extension workers on scientific knowledge and management techniques to the farmers for cattle farming should be encouraged. Improvements in cattle feeding patterns through green fodder cultivation are also encouraged, as farmers rely primarily on open grazing to feed their cattle’s. The government should also increase the availability of marketing and credit facilities, as the study area falls short in these areas.

Background: Excessive use of portable electronic devices causes neck flexion and the emergence of text neck syndrome (TNS). This study aims to explore the prevalence of TNS among medical students during the COVID-19 lockdown in Iraq.
Methods: A prospective cross-sectional web-based study was conducted from 1st to 20th March 2021 at the faculty of medicine, Diyala University, Iraq. A self-administered questionnaire was distributed among the medical students using Google Form through social media (WhatsApp group). The semi-structured questionnaire included the sociodemographic, the valid smartphone addiction scale-short version (SAS-SV), and the neck disability index (NDI). Univariate, bivariate, and multiple logistic regression were used to analyze the data. SPSS version 16. The statistical significance is considered at less than 0.05.
Results: Out of 273 medical students included in the study, 59.3% were males, unmarried (88.3%), and from the 1st year (21.6%). The mean age of students was 21.27 ± 1.74 years. The prevalence of text neck syndrome was 64.5%. About two-thirds (61.5%) of students were addicted to their smartphones and used them more than five h/daily (63.7%). Factors associated with neck disability were the students who did not warm up neck muscles before using the smartphone (OR = 8.796, 95% CI: 1.724 to 24.884), addicted to the smartphone (OR = 6.803, 95% CI: 3.455 to 13.397), experienced increase in daily hours using the smartphone during the COVID-19 related quarantine (OR = 5.370, 95% CI: 2.523 to 11.427), maintained smartphone use five hours and more daily (OR = 2.818, 95% CI: 1.422 to 5.587), had neck pain (OR = 2.876, 95% CI: 1.356 to 6.098), the female gender (OR = 2.756, 95% CI: 1.221 to 6.221), and those who did not have a frequent break when using the smartphone (OR = 2.693, 95% CI: 1.329 to 5.454).
Conclusion: In conclusion, the prevalence of neck disability was high among the surveyed medical students. Addiction and excessive smartphone use with a lack of attention to warm up the neck muscles before usage was the most prominent predictors of neck disability.
