• Enhancing CanSat Mission Safety: An Autogyro-Based Landing Solution

  Villacorta, Lalo; Chunga, Fabrizio; Aquino, Giovanni; Salvador, César D. (Springer Science and Business Media Deutschland GmbH, 2025-01-01)

  This paper presents an autogyro system for the safe landing of a class of compact satellites in miniature called CanSat. The proposal ensures the safe landing with fragile payloads by protecting the essential electrical and mechanical systems. The proposed autogyro system, consisting of six blades, is designed to reduce the impact force at ground by means of generating a passive lift force during descent that decelerates the CanSat in free fall. In addition, a decoupling mechanism, activated via telemetry, allows for the separation of primary and secondary payloads during descent, facilitating the deployment of the autogyro system. The methodology of this paper encompasses the autogyro design, its construction, its integration with a CanSat, its validation through data colection in free fall, and the analysis of results. Free-fall experiments were conducted from drones and buildings in close to wind-free conditions. The results showed that the optimal deployment of the autogyro system reduced the descent speed and protected the payload. The maximum deceleration registered during free fall was 4.94 ms-2 in 0.37 s. Future research may explore improvements in blade design and testing in various environmental conditions by means of sensing additional degrees of freedom during the free-fall dynamics.

  Vu, Oanh Thi Kim; Alonso, Abel Duarte; Carrillo, Brendali; Velasquez, Santiago; Buitrago Solis, María Alejandra; Nayak, Naresh P.; Nguyen, Chuyen; Cáceres Gutiérrez, Juan Pablo; Gonzalez Alandia, Britney Esther; Nguyen, Ngan Mai (Taylor and Francis Ltd., 2025-01-01)

  This research contributes to a deeper empirical and conceptual understanding of coffee tourism development. By using a qualitative cross-national approach encompassing five coffee producing nations and guided by the dynamic capabilities framework, this study examines the potential, capitalisation and further consolidation of coffee tourism. The experiences of coffee firm leaders were gathered through semi-structured open-ended interviews; the qualitative analysis uncovered 12 overarching dimensions and helped craft a conceptual framework, with implications for understanding coffee tourism development from a practitioner and conceptual perspective. For instance, coffee tourism's potential is mainly explained by the visitor-centred and firm-centred dimensions, while the individual firm and upstream supply-chain capitalisation dimensions illuminate capitalisation demonstrations. The findings also exhibited relationships with the dynamic capabilities framework. Among these, educational experiences elucidate coffee tourism's potential (sensing) the capitalization of financial gains (seizing) while working alongside the government underlines further tourism development (reconfiguring). Various differences were also noted between countries and regions.

  The role of social media influencers and eWOM in driving purchase intention: insights from SMEs in the gamarra cluster

  Medina, Franco; Lodeiros-Zubiria, Manuel Luis (Cogent OA, 2025-01-01)

  This study examines the influence of social media influencers (SMI) and electronic word-of-mouth (eWOM) on purchase intention (PI) within small and medium-sized enterprises (SMEs) agglomerated in the Gamarra textile cluster in Lima, Peru. Grounded in cluster theory and source credibility theory, the research aims to understand how these digital marketing strategies shape cluster-level brand trust (BT) and consumer brand engagement (CBE), ultimately influencing customer purchase decisions in one of the clustered SEMs. Data were collected via an online survey of 395 followers who engage with influencers frequently posting content related to the cluster. Using partial least squares structural equation modelling (PLS-SEM), the study confirms that both SMI and eWOM positively affect BT and CBE, although SMI has a stronger impact on CBE than eWOM. Additionally, CBE was found to be a more significant driver of PI than BT, reinforcing its role as a key construct in digital marketing effectiveness. The findings contribute theoretically by extending the application of source credibility and cluster theories to the context of agglomerated SMEs using shared branding. Practically, the study suggests that cluster managers should prioritise influencer-based strategies to build engagement and trust, especially when marketing budgets are limited. These insights offer actionable guidance for SMEs seeking to compete more effectively through clustering digital branding initiatives.

• Prevalence and exploration of HIV pre-exposure prophylaxis awareness in men who have sex with men aged 18–29 years in Lima, Peru, during 2021: A mixed methods study

  Tofeño, Diego; Uypan, Diana; Torres-Slimming, Paola (Elsevier B.V., 2025-07-01)

  Introduction: Pre-exposure prophylaxis (PrEP) is a therapeutic scheme that has shown effectiveness in reducing the risk of HIV infection through sexual contact. PrEP has been used in various countries globally and in Latin America as a public health measure. In Peru, the greatest increase in HIV incidence in recent years has occurred in the age group of 20–29 years and 15–19 years, this being an important range to be able to implement prevention measures. Objectives: To determine the prevalence of awareness of HIV PrEP and to explore the knowledge and attitudes regarding its use among men who have sex with men (MSM) aged 18–29 years in Lima, Peru. Methods: Explanatory sequential mixed method study whose central component is quantitative. A survey (non-probabilistic descriptive cross-sectional) and a virtual interview (phenomenological approach) were used for data collection. Results: Of 100 seronegative MSM surveyed, 49 % were aware of PrEP. In the qualitative component, it was found that most participants obtained information casually through their social networks. It was also found that they had significant concern about the adverse effects of PrEP, which was mentioned as a barrier to its use. Conclusion: Almost half of MSM are aware of the existence of PrEP, a medication that helps prevent HIV. However, it is important to find more reliable sources of information about PrEP because the fear of adverse effects and ignorance about it are limitations to its consumption.

• Comparison of Seismic Performance Levels of Five-Story Limited Ductility and Confined Masonry Structures, Lima, Perú

  Bendezu Romero, Lenin Miguel; Pabón, Deivy Hernández; Rufino, Yedsem Nuñez; Lazo, Malena Alessandra Serrano (Avestia Publishing, 2025-01-01)

  This study evaluates the seismic behavior of a five-story multifamily building by comparing two structural systems: Limited Ductility Walls (LDW) and Confined Masonry Walls (CMW). The structural models were developed using Estera 3D software, and the analysis was carried out exclusively through nonlinear static analysis (pushover). Four levels of seismic demand were considered: frequent, occasional, design, and maximum earthquakes. Both systems achieved the same structural performance levels according to code-based criteria: full operation for the frequent earthquake; operation with minor damage for the occasional and design earthquakes; and life safety for the maximum earthquake. However, quantitative results show better performance for the LDW system. For the design earthquake, the LDW system exhibited a maximum base shear of 1141.36 tons and a top-level displacement of 7.098 cm, while the CMW system reached 2371.63 tons and 2.9696 cm, respectively. In terms of spectral acceleration, LDW registered 935.20 gal compared to 1098 gal for CMW. For the maximum earthquake, the LDW system reached a displacement of 10.68 cm and a base shear of 1272.15 tons, whereas the CMW system reached 8.0686 cm and 2291.71 tons. These results indicate that, although both systems meet the established performance objectives, the LDW system demonstrates more efficient structural behavior and greater energy dissipation capacity under severe seismic events.

• Procedure to Ensure On-Time Delivery of Materials in Multifamily Housing Construction Projects Using Just-In-Time and Kitting In Small Construction

  De la Cruz Valdivieso, Alfredo Félix; Albornoz, Kelvin Eli Salinas; Roman, Karem Ulloa (Avestia Publishing, 2025-01-01)

  Construction companies are responsible for purchasing materials for the execution of construction projects, which consist of different stages; however, many times the materials do not arrive on time at the construction site. The material supply process is important within construction projects as it directly impacts the budget and schedule of the work. However, one of the most influential factors causing the delay in the delivery of material is the lack of a logistics plan for the supply of material in small companies. However, this leads to delays in the progress and delivery of the work. For this reason, this research focuses on ensuring the delivery time of construction materials in small construction companies for multi-family housing construction projects, specifically in the supply of materials through the use of the Just in Time and Kitting methodology, applying the use of an ERP. In this research, the following methodology is followed: (A) registration and analysis of information through expert judgment, (B) determination of the conventional material supply process in small construction companies, (C) development of the new supply process and (D) implementation of the new material supply process using the JIT and Kitting methodology. Finally, the result is a reduction in the delivery time of materials in the supply process, the metric being the average delivery time. In addition, a better management of the material supply process is obtained, in the logistics part. And the perception of the participants improved with the implementation of the new process. It is mainly concluded that the methodology used allows to ensure the delivery time of material, thus reducing the time in said process.

  Bazán, Darwin; Díaz, Leonardo; Ulloa, Karem (Avestia Publishing, 2025-01-01)

  In multifamily project construction, specialty subcontracting is common, but monitoring subcontractors, especially during finishing, presents significant challenges due to manual methods that are time consuming, make it difficult to detect deviations, and result in cost overruns and delays. This research proposes an automated monitoring procedure using a BIM model that integrates tools such as Revit, Navisworks, MS Project and Trimble Connect. The methodology includes four stages: analysis of information through surveys, identification of the traditional procedure in three companies, development of the new automated approach and validation in a pilot project. The results show a 42.4% reduction in daily monitoring time for subcontractors and a 41.4% reduction for technical personnel, in addition to improved access to real-time information. This optimizes coordination, reduces errors and ensures compliance with deadlines, significantly improving resource management in multifamily projects.

• Comparison of the FEMA P-154 Methodology with Seismic Analysis in the “Galería Tradición” of Cercado de Lima

  Lenin Bendezú, R.; Morales, Andre; Andrade, Carlos; Serrano, Malena (Avestia Publishing, 2025-01-01)

  The seismic vulnerability of buildings with considerable age represents a crucial challenge for urban resilience in a historic city like Lima. In this research, a sample of 30 publicly accessible galleries within the Cercado de Lima was evaluated. These structures were built with now-obsolete structural systems and are subject to deteriorated conditions. The FEMA P-154 methodology was applied to conduct rapid visual inspections and to classify the structures according to their level of seismic vulnerability based on the score established by the format. Additionally, a gallery with a critical FEMA score was selected for structural modeling in ETABS using previously scaled historical seismic records, following the guidelines of the E.030 Seismic Design Code. A Schmidt hammer test was also conducted to estimate the concrete strength of the selected building. The results show that more than one-third of the buildings exhibit high vulnerability and that the drifts obtained in the dynamic analysis exceed the limits established by the E.030 code. The FEMA P-154 methodology proved to be an effective tool for prioritizing structural interventions in urban contexts with limited resources.

• Damage States and Seismic Performance Levels of a Three-Story Confined Masonry Structure, Lima, Peru

  Lenin, Bendezu R.; Piero, Gomez R.; Jerico, Yshtay P.; Malena, Serrano L. (Avestia Publishing, 2025-01-01)

  This research addresses the issue of self-construction in the district of Lurigancho-Chosica, using the Asociación Pro Vivienda Paz y Desarrollo San Pedro y San Pablo as a case study. In this area, structural deficiencies are identified due to the use of non-standard materials and the absence of technical design. As a solution, the design of a three-story confined masonry dwelling is proposed, complying with the Peruvian National Building Code (RNE). Field data was collected from 15 representative homes using data collection forms to identify the number of projected floors and typical lot dimensions (240 m2). Based on this, a three-level confined masonry dwelling was designed, applying habitability and structural safety criteria according to standards A.020, E.030, and E.070 of the RNE. The structural design was carried out through a linear static analysis using ETABS software, determining dimensions and reinforcement of main elements. Then, the nonlinear behavior of the structure was evaluated using STERA 3D software, applying a nonlinear time-history dynamic analysis with seismic records scaled to the design spectrum (Standard E.030) using a seismic reduction factor R = 1. From the obtained interstory drifts, structural damage levels were classified according to the criteria of Zavala et al. [1], allowing the estimation of the dwelling's seismic vulnerability. Finally, structural plans were developed. The proposed design complies with current regulations and demonstrates good structural performance under severe earthquakes, representing a safe and technically reliable solution to the deficiencies observed in the self-construction context of the study area.

• Sleep Quality and Cardiovascular Adaptation in Health Sciences University Students

  Ortega-Contreras, Aruna Marcela; Caycho-Infantes, Maria Jazmin; Sánchez-Huamash, Claudia María (Universidad del Rosario, 2025-05-01)

  Introduction: It is important to have a good cardiovascular adaptation; sleep quality influences the autonomic system, affecting heart rate and blood pressure. The evidence about the relationship between both variables is still insufficient; its measurement is diverse, as are the results. The objective was to evaluate the association between sleep quality and cardiovascular adaptation in health sciences university students. Methods: Cross-sectional and analytical observational study, carried out on 106 students from the Faculty of a private university in Lima (Peru). The Pittsburgh Sleep Quality Index (psqi) was applied to evaluate the sleep quality, the Ruffier-Dickson Test to assess the cardiovascular adaptation, the Alcohol Use Disorders Identification Test (audit) to identify the risk of alcoholism, and the International Physical Activity Questionnaire (ipaq) to determine the physical activity. Results: 75.5 % of participants had poor sleep quality, and 26.4 % had inefficient or poor cardiovascular adaptation. The prevalence of inefficient or poor cardiovascular adaptation in those with poor sleep quality was 1.66 times higher than the prevalence of inefficient or poor cardiovascular adaptation in those with good sleep quality, but this difference was not statistically significant (pr = 1.66; p = 0.321). Conclusions: No association was found between sleep quality and cardiovascular adaptation in health sciences university students.
• Determining the potential of gastronomy tourism development in Vietnam through the dynamic capabilities lens

  Alonso, Abel Duarte; Vu, Oanh Thi Kim; Tran, Luong Ngoc; Carrillo, Brendali; Nayak, Naresh P. (Taylor and Francis Ltd., 2025-01-01)

  The purpose of this research was to examine Vietnam’s gastronomic resources as development tools to become a gastronomy tourism destination. Integrating the underpinnings of the dynamic capabilities approach, which predicates sensing opportunities, seizing them and reconfiguring, the study gathered the experiences of 35 executive chefs through semi-structured open-ended interviews. The ensuing analysis generated 12 dimensions and a conceptual framework. For instance, sensing is symbolised by internal, external, chef, and industry-related triggers, emphasising the nation’s gastronomic traditions, its growing international recognition, and chefs’ trailblazing role. The ‘enticing palates’ and ‘pre-empting potential’ dimensions are key seizing representations, the first underlying the distinctiveness of Vietnamese gastronomy and the second its extensive repertoire. Finally, reconfiguring is reflected by ‘banking on uniqueness’, which stresses maintaining a gastronomic identity while ‘championing the home-grown’ the involvement of gastronomy ‘gatekeepers’. The resultant framework provides an in-depth guide, enhancing the practical and conceptual understanding of gastronomy tourism’s development.

  This study examines the relationship between teachers' empathetic communication and their academic performance, focusing on two dimensions: empathetic concern and perspective taking. The main objective was to determine if there is a positive and significant relationship between empathetic communication and teaching performance in the university context. A descriptive correlational design was employed to analyze data collected from 364 students from private universities in Lima. Twenty-four items of empathetic communication and 23 of teaching performance were evaluated using a Likert scale survey. As a result, Spearman correlation analyses revealed a positive and significant correlation between empathetic communication and teaching performance (r = 0.211, P < 0.01). Furthermore, positive, and significant correlations were found between empathetic concern (r = 0.279, P < 0.01) and perspective taking (r = 0.166, P < 0.01) with teaching performance. It is concluded that empathetic communication is positively associated with teaching performance, highlighting the importance of developing empathetic communication skills in teachers to enhance their effectiveness in the classroom. However, caution is advised to balance empathy to avoid potential biases or deviations in teaching. It is recommended to focus teacher training programs on strengthening these social skills to optimize the teaching learning process.

  Bazán Lavanda, Eduardo; Camones Huerta, José; Raraz Rivera, Cecilia; Vásquez Ramírez, Nikole; Ayala Díaz, Pedro; Cruzado Grau, Carlos; Novoa Millones, Luis; Rodríguez Hurtado, Diana (Colegio Medico del Peru, 2025-04-01)

  Background: Obstructive Sleep Apnea (OSA) is often undiagnosed in heart failure (HF) patients. Early identification using affordable sleep studies could improve patient outcomes in resource-limited clinical settings like Peru. The objective was to determine the frequency of OSA in hospitalized HF patients using respiratory polygraphy (RP) (Sleep Study Type III). Materials and methods: A cross-sectional study was conducted. We included patients >18 years, hospitalized with exacerbated HF, and a STOP-BANG score ≥ 3. Enrolled patients underwent overnight RP using ApneaLink Air™. Data collected included clinical parameters, the Epworth Sleepiness Scale, and echocardiography results. Statistical analysis was carried out using R Studio. Results: Of 46 enrolled patients, 39 underwent successful RP; 84.61% were diagnosed with OSA. Patients exhibited a mean Apnea-Hypopnea Index (AHI) of 14.41 ± 10.08/h with mild (51.28%), moderate (25.64%), and severe (7.69%) cases. Symptoms associated with OSA included a lack of restorative sleep and concentration problems. RP data showed a mean minimum SpO2% of 76.85 ± 9.99% and an Oxygen Desaturation Index (ODI) of 20.01 ± 10.66. Correlation analysis indicated a strong positive correlation between AHI and ODI (r = 0.73, p < 0.001) and a moderate negative correlation between AHI and LVEF (r =-0.64, p = 0.056). Conclusion: This study reveals a high frequency of previously undiagnosed OSA among hospitalized heart failure patients in our institution, indicating the importance of active screening in this high-risk population.

• Use of BIM 4D Models to Improve the Dynamism of Construction Layout Planning in the Structural Stage of Multifamily Housing in Metropolitan Lima

  Huacre, Yhoel; Saldaña, Adalberto; Ulloa, Karem (Springer Science and Business Media Deutschland GmbH, 2025-01-01)

  Multifamily housing projects are developed in different stages of construction, each of which requires a specific site layout. This construction layout is a fundamental tool for planning the physical distribution of temporary installations at the worksite, ensuring order that does not disrupt workflows and maintains productivity. However, one of the main causes of inadequate layout planning is the poor dynamic analysis resulting from using a static layout, traditionally represented in AutoCAD drawings. For this reason, this research focuses on improving the dynamism of site layout planning in multifamily housing projects in Metropolitan Lima; specifically, in the structural stage, using 4D BIM models. The methodology used in this study is developed through the following steps: Analysis of the information gathered from the interviews and surveys conducted with experts; Determination of the traditional site layout process of the three evaluated projects; Development of the 4D BIM model; and Implementation of the model in the selected project. Finally, the implementation of the proposed 4D BIM model in the project results in a significant improvement of the dynamism in the temporary works planning, since it allows visualizing the relocations of temporary facilities during the project simulation and allows detecting temporary interferences. In addition, a more exhaustive analysis of the relocations of the temporary facilities on the job site is achieved, which facilitates better planning of the site layout.

• Procedure to Improve the Confidence in the Selection of Design Equipment Subcontractors by Implementing Set Based Design (SBD) and Choosing by Advantages (CBA) Methodologies in Multifamily Building Projects

  Celestino Romero, Milagros; Llontop, Grecia Gonzales; Román, Karem Ulloa (Springer Science and Business Media Deutschland GmbH, 2025-01-01)

  The selection process of design team subcontractors by real estate companies is crucial in construction projects, directly affecting the quality and efficiency of the final results. However, the lack of time to evaluate potential subcontractors can lead to inadequate selection and negatively impact the project development. This study proposes an innovative approach to improve confidence in the selection processes of design team subcontractors in multifamily building projects by implementing Set Based Design (SBD) and Choosing by Advantages (CBA) methodologies. These methodologies, supported by Excel Macros programming and data visualization in Power BI, aim to automate and optimize the selection process, reducing human intervention. The study follows these steps: (1) information registration and analysis by experts, (2) determination of the conventional subcontract selection process in the evaluated projects, (3) development of a new selection process based on SBD and CBA, and (4) implementation of this new process through Excel Macros programming applying SBD and CBA. The integration of SBD and CBA seeks to improve the transparency, reliability, and efficiency of the process, facilitating faster and more informed decisions. The results of the study show a 36% improvement in the confidence index, demonstrating the efficiency of the selection process. These findings support the automation of the selection process and highlight its contribution to a more accurate and efficient selection of subcontractors.
