Authors: M. Arif Bakhtiar E. M. Arif Bakhtiar E. , Seno Aji Seno Aji
Published: December 2024

Madiun city has an adequate waste infrastructure with final processing system using controlled landfill system. The data of waste transported to the final landfill in Final Landfill Sites (FLS) Winongo in Madiun reaches approximately 60% of the total existing generated waste. If this number is reviewed from the Millennium Development Goals targets by 70% in 2015, the number is still lacking. One of the influencing factors is the number and location of Temporary Landfill Sites (TLS) which are not in accordance with the requirements. It is important to identify the locations of TLS so they can be used optimally to increase the volume of waste transported to the FLS. The purpose of this study is to assess the TLS location in Madiun, both in terms of technical aspects and public opinion polling as TLS users using geographic information system tools. The analysis technique in this study used quantitative analysis performed to analyze the quantitative data related to the location of TLS and also qualitative analysis as a tool used to analyze a variety of information based on spatial analysis. By examining the feasibility of zoning pattern, it can be seen that the viable deployment zoning model with the dominant influence is a distance factor of TLS to the center of waste generation. It can be viewed from the fact that several TLS locations which are far away from the waste transport route are categorized as feasible and moderate. Based on the analysis, from the 36 TLS locations in Madiun, there are 12 TLS locations which belong to â€œnot feasibleâ€ criteria, 12 TLS locations which belong to â€œmoderateâ€ criteria and 12 TLS locations which belong to â€œfeasibleâ€ criteria.

Published: December 2024

Several accidents occurred in bundle conductor overhead transmission lines due to large amplitude wind induced vibrations. In evaluating possible causes of these accidents and to develop appropriate counter measures, it is important to have a clear interpretation of the nature of vibrations which actually occurs in the field. This study is carried out to interpret large amplitude field measured wind induced vibrations based on gust response analysis of overhead transmission lines. Time average characteristics of field measured wind-induced vibrations have been discussed based on spectral analysis and time series acceleration. Eigenvalue analysis results of developed three dimensional finite element (FE) model of transmission lines has been discussed with dominant frequency of field measured response spectrum. Wind force has been modeled based on field measured characteristics of wind. Gust response of transmission lines has been evaluated by using developed finite element model of transmission lines and discussed with field measured vibrations. Results from field measured data analysis and eigenvalue analysis showed that cause of large amplitude vertical vibration does not happen due to resonance and galloping of transmission line-A. In case of transmission line-B, some events are found due to resonance and others events have a possibility of galloping as well as gust responses. Random peaks have been observed in time series acceleration which implies impulsive response and well confirmed with numerically obtained gust responses by using FE analysis. Suspension span are more prone in torsional response which are well confirmed with numerical results

Published: December 2024

Parametric study was conducted to assess the time-dependent effect of creep on longterm behaviour of prestressed concrete Integral Abutment Bridge (IAB). Varying backfill soil types (dense sand, loose sand, stiff clay, soft clay) were provided behind the bridge abutment and the interaction was modelled using linear springs. The effect of backfill soil type on the behaviour of the bridge was assessed through 75-year time-history numerical simulations using Finite Element Method. CEB-FIP 1990 creep model was used to analyse the linear viscoelastic behaviour of creep. The result of the long-term response prediction showed significant increase in bridge displacement due to creep. Displacement due to creep was found to be nearly five times displacement due to instantaneous loading and abutment bending moment increased by more than two times that of live and dead loads. There is marked difference in girder and abutment shears, abutment axial load and abutment moment as a result of variation of backfill soil. The Denser the backfill soil the lesser the magnitude of the reactions on the bridge abutment and girder indicating a favourable choice of compacted sandy soil behind integral bridge abutments.

Published: December 2024

Understanding the safety climate of the contractorâ€Ÿs organization with regard to safety and risk in the workplace will provide an overview of the current safety culture of that organization. The perceptions and attitudes of the workforce are the important factors in assessing the safety needs in order to facilitate workplace safety improvement. Safety performance may fail if the organization does not take into account these current attitudes and perceptions. The aim of this study is to examine the factors and assessment of safety climate in the contractorsâ€Ÿ organizations. This study is carried out through questionnaire survey to gauge employee attitudes and perceptions using several attitudes dimensions. The full employee attitude survey questionnaire was divided into two sections which consists of 49 statements. The responses of this study were quite encouraging with 60% participants responded. However, only 38 valid sets of questionnaires were subjected to analysis. The findings indicated that there were many factors and indicators of safety climate that had been found from the literature review. In fact, the numbers of factors required in the safety climate measurements, or which factors were the most effective were always subjected to argument. From the review of safety climate factors, the most frequently measured dimensions were related to management, safety systems and risk, followed by work pressure, competence and rules or procedures. On the assessment of the contractorsâ€Ÿ safety climate, the total average scores for all dimensions were in levels of satisfaction with a score ranging from 6.48 to 8.04. Also, all the safety climate dimensions showed scores in the satisfactory values with a score above six (6) for the system interfaces of the contractor organizations using the safety climate matrix. Hence, the contractorâ€Ÿs organizations surveyed had the positive safety climate toward safety in their workplace.

Authors: Rao M.V. Krishna , V.S.S. Kuma V.S.S. Kuma , Kumar P. Rathish
Published: December 2024

The construction industry is commented for its ineffectiveness in delivering outcomes such as time and cost overruns, low quality and productivity, and subsequent poor customer satisfaction. To improve the probability of success in construction projects, choosing a suitable contractor is one of the major decisions to be taken by the clients. The choice of a suitable contractor is a multi-criteria decision making (MCDM) process. This paper employs Multi Attribute Utility Theory (MAUT), considering the multiplicative form of utility function, for ranking the prequalified construction contractors. In the present work, fifteen performance assessment criteria covering contracting company attributes, experience record, past performance, performance potential, financial stability and project specific criteria are considered for contractor evaluation. A case study of multi-storeyed building construction for which four contractors submitted bids is considered to illustrate the applicability and effectiveness of multiplicative approach of MAUT to rank the prequalified contractors. The proposed MAUT decision making methodology can be extended to decision making in other sectors also.

Published: December 2024

Hybrid composite materials have found extensive applications in many areas such as in the medical field, aerospace, automobile and in the sport industry, between others. The effect of stacking sequence of glass/carbon fibers on the tensile behavior of the hybrid composites was investigated in this paper. Five groups of hybrid composite laminates were produced using various proportions of woven E-glass/carbon fibers reinforced epoxy matrix and subjected to tensile tests. The results showed that the hybrid laminations that consist of three layers of carbon and two layers of glass provided the best tensile properties. Group D showed the maximum force results (9255.7 N) and maximum tensile stress (382.7 Mpa). For three or less number of layers in the composites, when using carbon fiber layers more than glass fiber layers, the tensile strength was found similar. Otherwise, the tensile load increased with increasing number of layers. Moreover, for the tensile force and the stress of the hybrid composite samples that consisted of three or more layers, a significant effect of the stacking sequence was noticed.

Published: December 2024

In solid waste management, landfilling is still widely practiced because it is convenient and consumer friendly. Unfortunately, many landfill sites have closed and cause problem in managing the waste. The purpose of this study is to suggest suitable and potential sites for landfill in Johor Bahru area through mapping technique and database system. Analytical Hierarchy Process (AHP) is a method for analysis and supports decision where multiple and competing objectives are involved. Fifteen parameters were identified to use in AHP process. In this method, the process is divided into hierarchy before pair wise comparison was done and the result is prioritizing according to their weightage. The process is continued with weightage evaluation and its consistency. Landfill site selection process involved many spatial data and strenuous in handling it. Geographic Information System (GIS) can give significant help because it can potentially handle large volume of data that need to be evaluated and processed. The method used in GIS is digitizing, buffering and overlays. As a result in AHP, the most important criterion is river weighted 0.149 of all criteria and the least important criteria are distance to main road weighted 0.028 of other criteria. In GIS method, there are six parameters selected which are main road, plantation, residential area, swamp, grassland and river coverage. The findings identified two potential sites for landfill area because it satisfied all given requirements. Integration of GIS and AHP is suitable to be used in landfill site selection process because it will helps in locating new landfill site that is environmentally, economically and socially wise.

Published: December 2024

Ground deformation and settlement caused by underground construction and tunneling works are inevitably avoided. Nevertheless, the impact of it can always be minimized and improvised by investigating amount of volume loss occurred from past historic data. This paper explores the amount of volume loss, in relates with tunneling techniques, ground properties as well as tunnel geometry. Early study explained two phases of volume loss, which are immediate ground loss during tunneling and long term volume loss occurred over the time. Preceding research conducts to identify the range of volume loss, in percentage. As the range of proposed volume loss is not self-dependent, therefore, it is deemed important to understand and investigate the volume loss with close proximate to the local geological property and tunneling techniques. This paper concluded that there are significant impact of tunnel construction techniques, ground properties and tunnel geometric to the percentage of volume loss. With this, the outcome and recommendation of the study will provide future direction for further comprehensive and better justification for ground settlement analysis occurred, during tunnel excavation.

Published: December 2024

A massive flood event, which hit Kelantan in 2014, has contributed a major destruction particularly at Kuala Krai district. An alternative approach to overcome this flood episode is by constructing dams. In this study, two dams proposed at the upstream of Galas and Lebir river, near Kuala Krai. This paper aims to assess the implementation of the proposed dams which is a structural approach at the upstream area to reduce flood hazard in Kelantan using a hydrodynamic model. A coupled of 1D and 2D hydrodynamic model have been tested to simulate the occurrence of flood events in Kelantan due to the proposed dams. The Digital Terrain Model (DTM) has been generated by combining the data sources; i.e. from Airborne LiDAR and SRTM. The design of proposed dams were defined based on 50 years flood characteristics proposed by UPEN and simulated into the DTM with different magnitudes of flood. The flow hydrograph and water level for 25, 100 and 200-year return period are generated as input data for initial and boundary conditions. River cross-sections and hydrodynamic roughness value of Kelantan catchment area are also used in the model. The flood that has been observed is focused on Kuala Krai area before and after the construction of the proposed dams. The results of maximum velocity and water depth from the hydrodynamic modelling results are then generated to produce flood impulse and flood hazard maps. The results obtained from the preliminary study of the hydrodynamic modelling at Kuala Krai after the development of the proposed dams showed that no flood occurred at the downstream based on the streamflow input consideration.

Published: December 2024

This study will lead to the analysis of unsaturated soil using Bishopâ€™s Simplified method which is one method to analyse slope stability in method of slices. In this study, the original formula for Bishopâ€™s Simplified method of saturated soil were modified by adding the element of matric suction, together with unsaturated friction angle, which was applicable for the analysis of unsaturated soil. In this study, 0 kPa and 20 kPa of matric suctions were applied in the analysis for both methods. From the analysis, the result indicates that the factor of safety (FOS) value of Bishopâ€™s Simplified method was 8.82 % higher than Felleniusâ€™s method for 0 kPa suction, which means that the soil is in saturated condition. For 20 kPa of suction, the FOS of Bishop (1955) was 6.84 % higher than Fellenius (1936). It can be concluded that, the reason for the relative accuracy of the Bishopâ€™s Simplified method is that in considering only the vertical equilibrium of any slice, there is no need to account for the horizontal components of the inter-slice forces.

Published: December 2024

During the last two decades, new container ship generations had come into service, as a result of the huge growth of container trade. New container ships with larger dimensions may lead to the need to develop many of container terminals by either just deepening in front of quay walls or by deepening and replacing existing quay cranes with ones of higher capacities. In Port Said area there are several ports that need to keep pace with the tremendous progress in ship sizes. One of these ports is the Port Said East Port container terminal located on the Mediterranean Sea to the north of Egypt. The diaphragm wall which services as a berthing structure in this port is one of the deepest diaphragm wall structures built in soft clay, 62.5m deep below lowest astronomical tide (LAT). The existing water depth in the front of the quay wall is 18 m. This paper describes a finite element approach for analyzing the behavior of the quay wall under development scenarios using static calculation only. The finite element programs PLAXIS 2D Version 8.2 and PLAXIS 3D Version 1.6 have been used to analyze the performance of the structural elements, soil and the overall stability under deepening and the increase of crane wheels loads to accommodate the expected future ship sizes. The results showed that the diaphragm quay wall can resist safely 4 m deepening in front of the quay wall considering the existing crane loads. While, the results showed that width of cracks limitation will restrict increasing quay cranes loads.

Walking speed, a fundamental aspect of transportation, varies across individuals and is influenced by factors such as age, gender, and environmental conditions. This study focuses on pedestrian behavior, particularly walking speed, at bottlenecks in Larkin Sentral bus terminal in Johor Bahru, Malaysia. The country's lower average walking speed compared to other Asian nations underscores the need for efficient urban transportation planning. The objectives are to determine pedestrian walking speeds and explore the relationship between pedestrian attributes and walking speed. Data was collected using video recording at selected walkways during peak and non-peak hours. The analysis, conducted using Minitab software, reveals a mean walking speed of 0.80 m/s, influenced by factors such as age, gender, carrying bags, using phones, attire, and time. Correlation analysis indicates that time and phone usage significantly affect walking speed. This study contributes valuable insights for enhancing urban planning, emphasizing the impact of technology and time on pedestrian experiences at bus terminals. The implications for urban transportation planning are substantial, advocating for custom interventions in pedestrian-friendly designs at bus terminals. The study challenges assumptions, highlighting the need for nuanced understanding and further research to comprehend the complex dynamics shaping pedestrian behavior.

Transportation of sediment is a critical issue in riverine environments, particularly in meandering channels where flow dynamics are complex. However, information regarding erosion and deposition processes in meandering channels is still limited. Therefore, an experimental investigation on the influence of discharge variation on the morphodynamics of a meandering channel has been carried out. The experimental investigation was conducted at the Hydraulic and Hydrology Laboratory, UTM Johor Bahru. The study investigates the flow profiles and the morphological changes of inbank flow conditions represented by shallow and deep flow depths. The findings revealed that Manning’s n in a deep flow depth was 60.12% higher than a shallow flow depth. Moreover, velocity at the channel bend was increased by 8.3% to 14.6% compared to the crossover along the channel. This indicates that the geometrical planform plays a crucial part on the variability of velocity in the channel. Therefore, the outcomes of this study could provide more effective river management strategies to resolve erosion and deposition issues in river engineering studies.

Authors: Mohd. Kassim Amir Hashim , Fatt Choi Lim
Published: December 2024

In frequency analysis based on analytical method, there are quite a number of probability distributions to be used for quantile estimation. The selection of inappropriate one will lead to either overestimation or underestimation of the quantiles. Thus the identification and selection of the best fitting probability distribution should be given emphasis. The L-moment method offers advantages over the conventional method of moment and thus is more reliable in the distribution identification. The focus of this study is on the identification and selection of best fitting probability distribution, based on L-moment ratio parameters and L-moment ratio diagram. The results show that the GEV (Generalized Extreme Value) distribution fits quite well to data series at most of the homogeneous regions and rainfall intervals.

Published: December 2024

The strategy of developing Islamic tourism in the archipelagos through the Shariah-Compliant Homestay Model in Sabah (MHPS) requires a holistic, structured approach. Key strategies include improving homestay infrastructure, providing courses for homestay owners on Sharia compliance, effective digital marketing, local community collaboration, religiously oriented tourism packages, and active involvement of religious institutions. The use of technology, efficient management, periodic evaluation, and developing local skills are crucial aspects of this Sharia-compliant homestay model. This approach aims to create a tourism experience that aligns with Sharia principles, positioning MHPS in Sabah as an attractive destination for Islamic tourists within the archipelago and globally. The success of this model depends on stakeholder cooperation and commitment to the continuity of Islamic tourism. The research method employed includes in-depth interviews with 30 homestay operators in Sabah, literature review, and field observation. The study shows that while Islamic tourism potential in Sabah and the archipelago is high, Sharia-compliant accommodation remains limited. Therefore, a comprehensive development strategy is essential to promote MHPS as a viable accommodation option for Muslim tourists. This strategy should involve government, entrepreneurs, and local communities, ensuring elements like cleanliness, gender separation, and halal food standards. Moreover, a strong marketing strategy emphasizing Islamic values and natural beauty preservation is necessary. The findings of this study are intended to guide relevant parties in maximizing Islamic tourism potential in Sabah and the archipelago, particularly in Malaysia, Indonesia, Brunei Darussalam, and other Asian countries. MHPS development is anticipated to increase the influx of Muslim tourists from Asia and beyond, generating economic benefits for local communities.

Explorando la violencia de pareja: perspectivas desde la diversidad sexual y de género
Authors:   Universidad de Almería, Mellinas Sánchez Lucía
Published: December 2024

El fenómeno de la violencia en la pareja ha sido estudiado con asiduidad en los últimos años gracias, principalmente, al aumento de estudios en relación con el género. Son temas recurrentes en la literatura de los últimos diez años aquellos en relación con la violencia visible (directa) e invisible (estructural, cultural y económica) hacia lo femenino. Si bien se ha observado su presencia, incluso en publicaciones de gran impacto, parece existir una falta de investigación sobre violencia ejercida por mujeres, tanto en relaciones heterosexuales como homosexuales, y en general, un desinterés en el estudio de las dinámicas de parejas lésbicas o mujeres bisexuales. Se trataría de una violencia más invisible, silenciosa y enmascarada.Es por esto que vemos de crucial importancia realizar una comparativa entre la violencia ejercida dentro de la pareja, de tipo homosexual y heterosexual. Buscamos ver las diferencias en las experiencias entre personas con un rol de víctima, perpetrador o en situación bidireccional, teniendo una perspectiva sinérgica sobre la vulnerabilidad a la hora de evaluar cómo se configura el sistema sexo-género, los estereotipos y cómo este afecta a todos sus integrantes.Consideramos que la violencia de género es un problema de salud pública. Ignorar este problema o no distinguir entre la violencia de género y la doméstica puede tener graves consecuencias para las víctimas, tanto a nivel social como institucional.
Universal Momentum Distributions and Short-Range Nucleon Correlations
Authors: Rubtsova O. A. , Pomerantsev V. N.
Published: December 2024

The problem of constructing universal two-nucleon momentum distributions for main NN-configurations $$^{1}{{S}_{0}}$$ and $$^{3}{{S}_{1}}$$–$$^{3}{{D}_{1}}$$ used to describe short-range nucleon correlations in nuclei has been studied. A new method for calculating such distributions has been proposed, and their properties have been studied. As illustrations, calculations for several modern realistic NN potentials, including non-nucleon degrees of freedom, have been provided. A new characteristic that determines the ratio of the fractions of high-momentum components for spin-singlet and spin-triplet NN distributions at low energies, which can be useful for comparative evaluation of the isospin dependence of short-range correlations in calculations with different NN interaction potentials, has been proposed.
Sociocultural factors in filariasis in an endemic village
Authors: Panigrahi Sunil Kumar , Gautam Anuradha
Published: December 2024

This is a case report about a woman in her 50s who presented with pitting oedema in her left lower limb due to chronic filariasis. This case highlights a myriad of interdependent sociocultural factors that contribute to the persistence of filariasis despite good mass drug administration coverage. These factors include a lack of appropriate local self-governance, low health awareness, distrust in public healthcare services and cultural acceptance of cow dung as a holy or hygienic substance. Prohibitive costs and limited options for cleaner domestic fuels, coupled with the practice of using cow dung cakes as fuel, not only increase the chances of indoor air pollution but also positively influence mosquito breeding through accumulated indoor and outside dirty, stagnant water. An understanding of the complex community-specific sociocultural factors associated with filariasis should inform broader policies for filariasis elimination in India and other low- and middle-income countries.

Published: December 2024

Primary Ewing sarcoma of the kidney (ESK) is a rare and aggressive malignancy often misdiagnosed as renal cell carcinoma (RCC) due to non-specific radiological features. Accurate diagnosis requires histology, immunohistochemistry (IHC) and molecular studies. We report the case of a female in her 20s presenting with abdominal pain, haematuria and weight loss, initially diagnosed with RCC. Imaging revealed a large renal mass and pulmonary embolus. Mechanical thrombectomy (MT) was performed, and biopsy of the pulmonary thrombus confirmed metastatic ESK through IHC and next-generation sequencing, identifying theEWSR1–FLI1gene fusion. The patient was treated with neoadjuvant chemotherapy (NAC) and interventional procedures. This case highlights the importance of considering ESK in differential diagnoses of renal masses and the utility of MT in obtaining diagnostic tissue, which allowed for the timely initiation of NAC and improved clinical management.

The objective of this research is to investigate the initial value problem of a higher-order matrix-type nonlinear Schrödinger (NLS) equation with discrete spectrum as simple and double poles (simple and second-order zeros [Formula: see text] and second- and third-order zeros under [Formula: see text] under zero boundary conditions (ZBCs). Specifically, we not only consider the analyticity, symmetries and asymptotics of the Jost function, scattering and reflection coefficients in the process of direct scattering, but also residue conditions, norming constants, RH problem and the reconstruction formula in the process of inverse scattering. There exist some differences between it and the RH method in the study of vector and scalar equations, like the order of each pole of [Formula: see text] being less than or equal to the order of the zeros of [Formula: see text] (assuming [Formula: see text] is a second- or third-order zero of [Formula: see text] under [Formula: see text]), etc.

In this paper, we study the Schrödinger–Hirota equation in birefringent fibers incorporating cubic–quartic dispersion. The model studied comes with a cubic–quintic nonlinear structure. The governing model introduced in this study is novel and original, and the obtained solitons have not been reported before. The Schrödinger–Hirota equation is an important modified structure within the higher-order NLSE that garnered significant attention in the fields of mathematics and physics, especially in the context of the transmission of solitons in water waves and optical fibers. To investigate optical solitons for this model, three widely applied in various research studies are implemented for our governing model. These methods are the Unified Riccati expansion method, the addendum to Kudryashov’s method, and the addendum to the modified Sub-ODE method. A variety of solutions have emerged with this governing model, including bright, dark, singular solitons and the hybrid of these solitons. Also, Jacobi and Weierstrass doubly periodic-type solutions are recovered, which, with selected parameters, these solutions give solitons. Furthermore, for more illustration of the obtained solutions, a detailed discussion with a graphical presentation is presented.

TANGO2 deficiency disorder, a rare autosomal recessive genetic disorder characterised by biallelic loss‐of‐function variants in the TANGO2 gene, was first described in 2016. This disorder involves the transport and Golgi organisation homologue, impacting Golgi membrane redistribution into the endoplasmic reticulum. Clinically, affected individuals exhibit a multiorgan phenotype, with prominent neurological manifestations such as developmental delay and regression. Metabolic crises, triggered by minor infections or fasting, are a hallmark of the disorder. We present the case of a 5‐year‐old boy diagnosed with TANGO2 deficiency disorder who experienced a refractory‐to‐treatment ventricular arrhythmia storm. The patient’s clinical course was marked by rhabdomyolysis‐induced muscle pain, weakness and dark urine. Despite aggressive medical management during intercurrent illness, including hyperhydration, maintenance of normoglycemia and correction of electrolyte abnormalities, the patient’s condition deteriorated, leading to a life‐threatening ventricular arrhythmia storm. In a life‐saving therapeutic approach, the patient underwent a thoracoscopic left sympathectomy during extracorporeal membrane oxygenation (ECMO) support. Remarkably, this intervention resulted in the termination of the ventricular arrhythmia storm. The case underscores the challenges in managing TANGO2 deficiency disorder‐associated complications and highlights the potential role of innovative interventions, such as sympathectomy during ECMO, in critical and refractory cases. This case contributes to the understanding of the clinical spectrum of TANGO2 deficiency disorder and emphasises the need for further research into targeted therapies for this rare metabolic condition, where current treatment strategies focus on symptom management.

Published: December 2024

Background: Breastfeeding is vital for infant nutrition, bonding, and overall health. However, challenges can arise with the presence of tethered oral tissues, commonly known as labial (lip) tie or lingual (tongue) tie, otherwise known as ankyloglossia. This case study explores the differential resolution of breastfeeding symptoms in a one‐month‐old infant with both labial and lingual ties. It outlines the diagnostic process, surgical interventions, and postoperative care, emphasizing the importance of detailed characterization of symptom resolution associated with a lingual and labial frenectomy.

Case Presentation: The one‐month‐old male presented with 11 symptoms of feeding difficulties. Sequential surgical releases were performed for the labial and lingual ties, with a ranula also addressed. Detailed symptom assessments were conducted at one, two, and 4 weeks postsurgery, revealing differential responses to labial and lingual releases.

Results: The results show that 81.8% of symptoms resolved after labial and lingual surgeries, with some symptoms responding specifically to either labial or lingual release. The study suggests that surgical intervention can significantly improve breastfeeding outcomes, including for patients who may not have access to sufficient lactation counseling resources.

Conclusion: This single case study provides a valuable starting point for the exploration of which dysfunctional breastfeeding symptoms are associated with a labial tie versus lingual tie. Further research with larger samples is warranted to explore optimal treatment strategies for diverse parent–baby dyads experiencing breastfeeding difficulties, or whose access to lactation support services is limited.

The use of mobile devices has become pervasive in recent times, constituting an essential component of daily life. Mobile phones have enabled certain minorities to attain access to the Internet, news, and knowledge, thereby indicating their potential to reduce the digital divide experienced by ethnic groups and those from low socioeconomic backgrounds. This phenomenon has generated academic interest in the utilization of mobile devices to facilitate learning, as these devices merge the lines between computing and communications, giving access to both. The objective of this study is to ascertain the inclination of Peruvian higher education students to use mobile devices for learning. This will be achieved through the use of an anticipated model based on artificial neural networks (ANNs). ANNs are supervised machine learning techniques that imitate the organization and operation of the human brain to process data and render decisions. ANNs are computer systems that can learn from observation and experience, much like the human brain, and can subsequently use the acquired knowledge to recognize patterns and make predictions. The objective of this study is to assess the intention of Peruvian tertiary education students to employ mobile devices for learning by creating a predictive model that relies on ANNs. Among the main findings, it is evident that the ANN with optimal performance has 10 neurons within its hidden layer. Factors such as experience with virtual subjects, frequency of use, and coverage are crucial for the two intention variables. This enables directed prediction efforts towards the most significant variables identified by their importance.
