Application of digital technologies: the case of virtual Masses(Associacao Iberica de Sistemas e Tecnologias de Informacao, 2024-01-01)In times of adversity, such as the recent COVID-19 pandemic, the bishops and priests of the Peruvian Catholic Church took on the task of transmitting Masses through digital environments. The aim of this study is to measure the reception that the transmission of the “virtual” Mass reached among the Catholic faithful of Lima and the evaluation of this experience. Its approach was quantitative with a correlational design. The online questionnaire “Experience of the Mass during the pandemic” was applied to identify the way in which 836 Catholic faithful from Lima have lived the experience of the transmission of “virtual” Masses. The findings showed that the use of technology and virtual media for religious practice is valued differently, with women being more religious than men. It was observed that young people have a greater understanding of the inequality between “face-to-face Mass” and “virtual Mass”.Acceso restringido temporalmente

Web Application for Early Cataract Detection Using a Deep Learning Cloud Service(Springer Science and Business Media Deutschland GmbH, 2024-01-01)Cataracts are a degenerative disease that causes opacity in the crystalline lens. They represent one of the leading causes of blindness worldwide, making early detection crucial to prevent severe damage to patients. Current studies on cataract detection face limitations, particularly due to the high cost of imaging devices and their limited accessibility for users. In this study, we propose a web application that utilizes a Deep Learning service to analyze fundus images and provide a cataract diagnosis. This application aims to assist healthcare personnel in medical centers lacking specialist ophthalmologists or facing limited resources for cataract diagnosis. We designed the physical architecture of the application using Azure services, enabling its deployment and operation in the cloud. Azure Custom Vision facilitated the training of our model with a dataset of 1446 fundus images, encompassing both cataract and non-cataract cases. Subsequently, we implemented the web application using React.js and Express.js technologies, integrating the Deep Learning model to perform diagnoses through the web interface. The results demonstrated that the model achieved sensitivity, specificity, precision, and accuracy levels exceeding 90%, showcasing that our proposed tool allows for reliable initial cataract diagnoses in patients without the need for high-cost equipment.Acceso restringido temporalmente

Mobile Application for Calorie Control Using Machine Learning(Springer Science and Business Media Deutschland GmbH, 2024-01-01)Overweight is a serious problem in Peru, and compliance with a healthy and balanced diet is essential for its management. Despite the existence of different types of diets and meal plans, people still find it difficult to comply with the treatment. Also, lack of access to adequate nutritional information and lack of follow-up in implementing a low-calorie diet can demotivate people and reduce the effectiveness of the process. To reduce this problem, a mobile application is presented that allows the control of the caloric intake of food, based on food suggestions using Machine Learning. For this purpose, the Support Vector Machine algorithm is applied to train a model that recommends personalized food to users according to their preferences. This is how the application allows users to easily access personalized food recommendations by analyzing their preferences and caloric needs individually. As a result, it has achieved a Percentage of Caloric Recommendation Satisfaction of 90.5%, a Percentage of Accepted Recommendations of 94.2%, and a Percentage of Usage Satisfaction of 92.6%. These results support its effectiveness and ease of use. It is expected that this proposal will have a positive impact on the fight against overweight in Peru.Acceso restringido temporalmente

Predictive Model for Accurate Horticultural Product Pricing Using Machine Learning(Springer Science and Business Media Deutschland GmbH, 2024-01-01)The trade of horticultural products is a crucial sector in the local economy of Lima, Peru. Microenterprises dedicated to this activity face various challenges, including demand volatility. This volatility can decrease the likelihood of generating profits and impact the stability of the business, primarily due to the challenges associated with adjusting selling prices. To address this issue, our proposal is based on implementing the XGBoost algorithm, which has the capability to handle heterogeneous data and variables of different types. This algorithm leverages historical data to provide accurate and up-to-date price recommendations for horticultural products. This, in turn, enables micro-entrepreneurs to make informed decisions when setting prices, thereby achieving expected benefits and enhancing their competitiveness. The integration of our project with microenterprises in Lima has the potential to mitigate the risk of economic losses by offering greater accuracy in predicting future market prices. Through the development of our project, we have achieved a high level of accuracy in forecasting future prices, reaching a minimum of 90% when compared to actual prices.Acceso restringido temporalmente

Abjection, gender violence and andean gothic in ‘Sangre coagulada’, by Mónica Ojeda(Eduem - Editora da Universidade Estadual de Maringa, 2024-01-01)The article analyzes ‘Coagulated blood’ (2020) by Mónica Ojeda. It is intended to demonstrate that in said text a complaint is presented against the violence suffered by women, but also, the capacity of the latter to face such violence. Ojeda tells the story of a disabled teenager, who was the victim of a sexual assault and is disowned by the rest of the town due to her strange behavior and because her grandmother performs abortions. In this context, the story shows how the adolescent, who is considered abject (Kristeva), develops the capacity for agency (Sen), thanks to the affidamento (Milan Women's Bookstore) that she achieves by living with her grandmother. By virtue of the above, La Ranita, as the girl is called, learns to face the people who try to attack her and her family. To tell the story, Mónica Ojeda appeals to andean gothic, an aesthetic that uses andean magical mythical references as a substrate.Acceso abierto

Process Architecture for the Integration of Outpatient, Hospitalization and Emergency Services in Level III Hospitals in Peru(Springer Science and Business Media Deutschland GmbH, 2024-01-01)Peru has a fragmented health system, which limits access to its health services because the people seeking medical services can only be treated in specified health centers that are determined by their health insurance. Additionally, this causes each health provider to count and manage their processes and information in an isolated and independent manner. In the Peruvian case, this generates an overload in public health services, since, of the 83.3% of insured nationwide, 73.1% belong to the public sector. Therefore, a process architecture is presented, based on the Zachman framework, that integrates the processes of health services (outpatient, hospitalization and emergencies), as well as an Information Technology (IT) process that supports them. The architecture aims to ensure that level III hospitals in Peru have standardized processes and information, as well as to guarantee their application regardless of the hospital regime. The processes were designed based on information from two Peruvian level III hospitals, belonging to the Sistema Integrado de Salud (SIS) and Seguro Social de Salud (EsSalud). A time simulation of the current processes and those proposed by the architecture, show an average improvement percentage of 69% in the outpatient process, 27% in emergencies and 7% in hospitalization. In addition, an expert judgment was made obtaining a very high assessment on the usefulness of the architecture.Acceso restringido temporalmente

Psychometric evidence of the Implicit Theories of Intelligence Scale (ITIS) in Peruvian university students(Centro Interamericano de Investigaciones Psicologicas y Ciencias Afines, 2024-01-01)Intelligence is a psychological attribute that has been related to academic performance (Ayoub et al., 2022) and creativity in university students (Sánchez-Cid et al., 2018). In this sense, Dweck et al. (1995) remarked the importance of self-theories or self-perception about one's own intellectual capacity and the belief of whether it can be modifiable, for the achievement and academic success in higher education students. According to Sternberg (1985) theories explaining intelligence have been organized into two categories: implicit and explicit. Implicit theories refer to particular and personal beliefs based on experience and explicit theories emphasize the biological component and the conception of multiple intelligences. In other words, implicit theories of intelligence constitute a self-perception about one's own intellectual capacities. In this regard, studies have demonstrated their importance in the educational field, as they are related to motivation, academic performance and general well-being; however, despite the fact that empirical evidence has demonstrated the importance of implicit theories of intelligence in the field of higher education (Costa & Faria, 2018), in Peru there is no valid and reliable measure to fill the existing knowledge gap on this subject. Therefore, the main purpose of this research was to analyze the psychometric evidence of the Implicit Theories of Intelligence Scale (ITIS) (Dweck, et al., 1999). The study is framed in an instrumental design, for which 1319 university students were selected, through a non-probabilistic sampling, with the average age of the participants being 20 years old, most of them being women (57.1 %). Initially, the ITIS statements were translated into Spanish, the relevance of the linguistic adaptation was reviewed through the back translation procedure recommended by the International Test Commission (2005). Then, the version translated into Spanish was applied on a sample of 319 participants with whose data the Exploratory Factor Analysis (EFA) was performed, the results showed that the translated version replicates the structure originally proposed by Dweck et al. (1995). Subsequently, on a sample of 1000 participants, this two-dimensional structure was corroborated in which the Entity Theory (ET) and the Incremental Theory (IT) were differentiated. A Confirmatory Factor Analysis (CFA) was carried out with the method of unweighted least squares with mean and variance adjusted (WLSMV). The results showed that of the three models tested (Model 1, original model; Model 2, with correlated errors; Model 3, reduced version) the second model in which errors are established between items 1 and 2 and 7 and 8 is the one with the best fit indices (CFI = .993; TLI = .987; RMSEA = .047 [.027 - .068]); also, its internal structure is solvent and invariant according to sex. On the same sample (n = 100), validity was analyzed in relation to other constructs and it was determined that the TE is negatively related to Consistency of Interest (CI), Academic Self-Efficacy (AA) and Dispositional Optimism (OD), while the TI is positively related to Perseverance Effort (PE), AA and OD. The reliability of the ITIS was determined by internal consistency, both factors reported optimal omegas coefficients (TE, ω = .786; TI, ω = .741); in addition, the measure showed temporal stability in its scores after two weeks with respect to the first application (CCI = .751 for TE and CCI = .761 for TI). In sum, the ITIS is a measure that presents adequate evidence of validity and reliability in Peruvian university students; its scores are consistent, interpretable and invariant according to sex.Acceso abierto
