Development of a racing video game using the smartphone as a steering wheel(International Institute of Informatics and Systemics, IIIS, 2022-01-01)Uno de los géneros más populares de videojuegos han sido los de carreras. Aquí hay una fuerte demanda por controladores con diseño de timón que hacen de la experiencia de juego más inmersiva y entretenida. No obstante, estos controladores suelen ser caros y no todos los jugadores pueden adquirirlos. En el afán de encontrar una alternativa más accesible que ofrezca la misma inmersión a los jugadores de este género se implementó SmartDrive, un videojuego de carreras para Android programado en Unity 3D. SmartDrive utiliza dos smartphones Android 5.0 o superior conectados vía un hotspot WiFi, uno se usa como pantalla del juego y otro como un timón gracias a sus sensores de movimiento. La validación contó con 30 participantes que jugaron y brindaron sus valoraciones mediante una encuesta. Los resultados finales destacaron la aceptación de SmartDrive en los participantes al ofrecer una experiencia inmersiva con una mecánica de juego novedosa e intuitiva, e implementada con recursos más económicos. Este estudio mostró el potencial de SmartDrive como una alternativa accesible y sin perder el grado de entretenimiento.Acceso abierto

Anxiety and mental health in the face of COVID-19(Elsevier Espana S.L.U, 2022-10-01)En estos últimos años el mundo estuvo en una situación crítica generada por la pandemia de la COVID-19, la cual afectó en muchos aspectos a la sociedad, tanto en lo económico como en la salud física, paralelamente trajo consigo la pérdida de vidas humanas, repercutiendo negativamente en la población en general1. A raíz de los primeros casos de SARS-CoV-2 detectados en el mundo, los distintos gobiernos optaron por medidas de prevención para contrarrestar la expansión de este virus, sin embargo, lo que no se pudo prever fue el efecto que tuvo en la salud mental. Como sabemos, la enfermedad provocó diferentes cambios en la sociedad, causando incertidumbre en las personas, por ende, el bienestar emocional se vio afectado2. En la población adolescente, la afectación emocional principal se debió a problemas familiares, baja autoestima, la muerte de un pariente, por disfunción familiar o por la pobreza en la que viven., Asimismo, el aislamiento social influyó en la salud mental de estos jóvenes3. Los problemas como el estrés postraumático, los trastornos afectivos y la atención con ansiedad, afectan tanto a los varones como a las mujeres. En algunos casos los hombres externalizan su estrés con actos de violencia, mientras que las adolescentes lo reprimen. En consecuencia, se deben de brindar alternativas o medidas que ayuden a afrontar el estrés producido por la cuarentena. En ese sentido, es válido seguir las siguientes recomendaciones: primero, un cambio en la alimentación a base de proteínas y carbohidratos, asimismo, actividades deportivas y ejercicios de relajación como la RMP de Jacobson; segundo, la comunicación con familiares cercanos que permitan tener una sostenibilidad emocional, con ayuda profesional y las escuelas de padres; tercero, las entidades educativas y universitarias deben realizar investigaciones que permitan identificar los problemas de ansiedad y de salud mental en los adolescentes mediante instrumentos como el MINI-KID, la escala orientada al DSM del Child Behavior Checklist (CBCL), entre otros; finalmente, el uso de las TIC para el tratamiento de la ansiedad con la finalidad de reemplazar a los medios de comunicación tradicionales (televisión y radio)4,5. En conclusión, se infiere que en situaciones de fallecimiento de un pariente, pobreza o problemas familiares, los jóvenes que reciben charlas y orientaciones logran mejorar su autorreconocimiento y, por ende, su autoestima. Por lo tanto, la salud mental está vinculada con el bienestar emocional, la satisfacción por la vida, y el poder resolver problemas.Acceso abierto

Poverty, Household Structure and Consumption of Foods Away from Home in Peru in 2019: A Cross-Sectional Study(MDPI, 2022-09-01)The aim of this study was to evaluate the probability of buying food away from home according to the type of household using the logit model, as well as the sociodemographic characteristics of the heads of household, and how much income expenditure represents. A cross-sectional study was carried out using the National Household Survey (ENAHO) 2019 database. After joining the database, the household type variables were created. To calculate the probability with the “logit” model of purchase, the variables—family size, income, types of household, and total expenditure—were selected as a measure of the purchasing power of the family. A statistically significant association (p < 0.05) was found between the probability of consumption and the variables: age of household members, predominance, nuclear without children–married, nuclear with children–cohabitant, nuclear with children–widowed, nuclear with children–separated, extended, compounded, poor not extreme, and not poor. The bulk of families was represented by nuclear families (61.97%). The highest expenditure in the CFAH was for families defined as composite with a yearly average of USD 1652.89 (equivalent to PEN 5520.67). Observing the expenditure on food consumed outside the home through the composition of households can allow a better approach to offer educational measures. This information can be helpful to developers of educational issues.Acceso abierto

Brandalism and social protest: interactions and digital identities around vandal advertising(Universidad de Chile, 2022-01-01)Brandalism or subvertising refers to the advertising discourse that adopts anti-consumerism positions to make a social critique. Considering the context of social protest during the pandemic, we investigated discourses forms of brandalism through the digital platform Facebook. Therefore, this article analyzes the interactions of political consumers in relation to the themes of brandalism of the Malditos Publicistas account on Facebook (@Malditospublicistas) in the context of the protests against the government of Manuel Merino during 2020, in Peru. Based on the case study from a sociosemiotic perspective, we identified thematic axes comprised in the ethical-political relationship of the brandalist discourse, as well as digital interactions that we categorized as "lurkers", "spectators", "activists", and "publishers". The results indicate a greater participation of lurkers and publishers reactive to ethical discourses than activists who favor the political agency of the discourse.Acceso abierto

Virtual tools in distance education: university satisfaction regarding its application as part of teaching strategies(Institute of Advanced Engineering and Science, 2022-11-01)When virtual education was implemented in Peru, the limitations of teachers in technological management were evident. For this reason, the research seeks to analyze the perception of university satisfaction regarding the use of virtual teacher tools as part of teaching strategies, in order to improve virtual teaching-learning, achieving student motivation and facilitating this meaningful learning through the use of virtual tools. The method used according to the investigative approach is qualitative, according to its scope it is descriptive and correlational. During the development of the research, it was identified that the satisfaction regarding the use of virtual tools by the teacher is focused on the critical, constructive and positive attitude towards virtual tools and in the acquittal of students' questions regarding the use of virtual tools. On the other hand, the indicator that is related to low student satisfaction focuses on the low diversity of methodological strategies used for the development of virtual learning sessions. Likewise, the Chi-square test shows the significant relationship between the perception of the teacher's competences regarding the use of virtual tools and the perception of the quality of the teaching offered to students during distance education.Acceso abierto

Evaluation of the learning management system and its relationship in the perception of engineering students(Institute of Advanced Engineering and Science, 2022-12-01)The objective of this study was to identify the results of the learning management system (LMS) functionality, and its relationship in the perception of electronic engineering students. The results serve as a basis for continuous improvement for the higher institution, because these systems are tools that have the purpose of improving the performance and retention of the student in the virtual teaching-learning process. Initially, the reliability of the data collected was determined using Cronbach's Alpha, obtaining a consistency coefficient of 0.868. After processing the data in the SPSS software, using the 5-level Likert scale, it was determined that the indicators that present a better perception are related to the design and ease of navigation. However, 21.4% do not fully agree with the functionality, due to the technical problems presented when downloading the study material. The effect generated by the optimal functionality of the LMS is 70.87% satisfaction in students. The Chi square test validated the cause-effect relationship, with a significance of 0.000, between the functionality of the LMS, on the perception of the students. It determined that the indicators with a greater relationship refer to design, availability (connectivity) and ease of communication and interaction with the teacher and their peers.Acceso abierto

Sentiment analysis through twitter as a mechanism for assessing university satisfaction(Institute of Advanced Engineering and Science, 2022-10-01)Currently, the data generated in the university environment related to the perception of satisfaction is generated through surveys with categorical response questions defined on a Likert scale, with factors already defined to be evaluated, applied once per academic semester, which generates very biased information. This leads us to wonder why this survey is applied only once and why it only asks about some factors. The objective of the article is to demonstrate the feasibility of a proposal to determine the degree of perception of student satisfaction through the use of data science and natural language processing (NLP), supported by the social network twitter, as an element of data collection. As a result of the application of this proposal based on data science, it was possible to determine the level of student satisfaction, being 57.27%, through sentiment analysis using the Python library "NLTK"; Thus, it was also possible to extract texts linked to the relevant factors of teaching performance to achieve student satisfaction, through the term frequency and inverse document frequency (TF-IDF) approach, these being those linked to the use of tools of simulation in the virtual learning process.Acceso abierto

An application of Six Sigma DMAIRC model: case study of a manufacturing organisation(Inderscience Publishers, 2022-01-01)Global competition extends several challenges to micro, small and medium enterprises (MSMEs) organisations. There is an increasing need for these firms to adopt strategies for productivity improvement. Six Sigma is a data driven methodology supported by statistical, mathematical and managerial techniques for improving the bottom line effectively. In this paper, an application of DMAIRC model of Six Sigma is presented in context to a quality improvement initiative in an MSME organisation. DMAIRC is an effective alternative to linear DMAIC model, as it provides opportunity to review results and diagnose additional improvements. The additional improvements are checked for feasibility and implemented through additional improvement cycles. The study also demonstrates integration of the quality management techniques such as Pareto analysis, cause and effect analysis, current reality tree, design of experiments, and integrated AHP-TOPSIS in the DMAIRC model stages. The paper provides a roadmap for real life applications of Six Sigma methodology following the DMAIRC model.Acceso restringido temporalmente

The expulsion of the different. Discipline, sanitation, and illness in “Lorenzita” by Manuel Atanasio Fuentes(Universidad Catolica Silva Henriquez, 2022-07-01)The article analyzes “Lorenzita” (1898) by Manuel Atanasio Fuentes, a text that can be considered as the first literary manifestation that addresses the issue of sexual dissidence in Peru. An attempt is made to show that this text shows the rejection of the leadership élites regarding the body of the homosexual, which is considered a sick and abject body. This position is related to the disciplining and sanitation practices that this élite develops against the identities that it is thought should not be included in the modernization projects of the Peruvian nation at the end of the 19th century.

FoMO, Facebook Addiction, and Loneliness as Determinants of Phubbing in University Students from Lima(Pontificia Universidad Catolica de Chile, 2022-01-01)Phubbing is a communication disturbance that consists in snubbing the company of another person by paying attention to one’s mobile phone. It is common in young people and has implications for the quality of social interaction. The aim of the study was to determine the relationship between Fear of Missing Out (FoMO), Facebook addiction, feelings of loneliness, age, and phubbing. Using convenience sampling, 209 students from a private university in Lima, Peru, were selected. Their ages ranged from 17 to 37 years, with a mean age of 21.28 years (SD = 3.42). Most were women (64.1%). The study adopted an explanatory design. The Phubbing Scale, the FoMO Scale, the Bergen Facebook Addiction Scale, and the Jong Gierveld Loneliness Scale were administered. The data were analyzed through Pearson’s linear correlation coefficients and a linear regression model, which showed that FoMO and Facebook addiction have direct effects on phubbing; that age has indirect effects on its variance; and that loneliness does not significantly explain this behavior.Acceso abierto

What Drives Abdominal Obesity in Peru? A Multilevel Analysis Approach Using a Nationally Representative Survey(NLM (Medline), 2022-08-19)Abdominal obesity (AO) is a serious public health threat due to its increasing prevalence and effect on the development of various non-communicable diseases. A multilevel analysis of the 2019 Demographic and Family Health Survey (ENDES in Spanish) using the Latin American Diabetes Association (ALAD in Spanish) cut-off points was carried out to evaluate the individual and contextual factors associated with AO in Peru. A total of 30,585 individuals 18 years and older were included in the analysis. The prevalence of AO among Peruvians in 2019 was 56.5%. Individuals of older age (aOR 4.64; 95% CI: 3.95-5.45), women (aOR 2.74; 95% CI: 2.33-3.23), individuals with a higher wealth index (aOR 2.81; 95% CI: 2.40-3.30) and having only secondary education (aOR 1.45; 95% CI: 1.21-1.75) showed increased odds of presenting AO compared to their peers. At a contextual level, only the Human Development Index (aOR 1.59; 95% CI: 1.17-2.16) was associated with the development of AO. A high Human Development Index is the contextual factor most associated with AO. It is necessary to formulate and implement new public health policies focused on these associated factors in order to reduce the prevalence of OA and prevent the excessive burden of associated noncommunicable diseases.Acceso abierto

Stress and Anxiety Reduction Effects of a Reiki Program During the COVID-19 Pandemic Among Employees in Lima, Peru(Lippincott Williams and Wilkins, 2022-09-01)Evidence has been found of how the coronavirus disease-2019 (COVID-19) pandemic has increased stress and anxiety indicators. Against this background, the present research aims to determine the effect of a distance Reiki intervention program on stress and anxiety during the period of isolation due to COVID-19 among people working in the city of Lima, Peru. The related hypothesis was that distance Reiki would generate a reduction in stress and anxiety levels. It was a quasiexperimental design with pre- and posttests, with nonprobabilistic purposive sampling. In total, 28 employees participated (12 in the experimental group and 16 in the control group). As part of the method, the following instruments were used: the EPGE, IDARE, and Coronavirus Anxiety Scale (CAS). There was a large decrease in the distress parameter (Cohen's d = 1.006), as well as in the state anxiety parameter (d = 1.678) and a large increase in eustress (d = 0.921). Similarly, there was an overall reduction in the trait anxiety parameter (d = 0.373) in all cases as compared with the control group. Coronavirus anxiety showed no major impact. These results provide initial evidence on the effects of distance Reiki among Peruvians and provide the basis for promoting this cost-effective therapy, generating a practical and social contribution.Acceso restringido temporalmente

The psychosocial impact of dental aesthetics and experiencing discrimination at a Peruvian public hospital among outpatients(Public Library of Science, 2022-08-01)Aim To evaluate the association between outpatient's perceived psychosocial impact of dental aesthetics and experiencing discrimination at a Peruvian public hospital. Material and methods Cross-sectional study in a Peruvian public hospital, where 207 outpatients (18-30 years old) were surveyed. We asked participants about self-reported experiences of discrimination in the last six months at a Peruvian public hospital using a question from the Peruvian National Household Survey on Living Conditions and Poverty (ENAHO) 2017. We also measured the perceived psychosocial impact of dental aesthetics with the Psychosocial Impact of Dental Aesthetics Questionnaire (PIDAQ). Additionally, we evaluated age, sex, ethnicity, education, income, and reason for being discriminated against. Association was assessed with Poisson regression using a robust estimator of variance and reporting prevalence ratios with 95% confidence intervals in crude and adjusted models. Results About two out of every five participants having experienced discrimination at a Peruvian public hospital in the last six months. On our adjusted estimates, we found discrimination to be positively associated with two components of the psychosocial impact of dental aesthetics, which were social impact (PR 1.02, 95% CI 1.00-1.04) and the psychological impact (PR 1.07, 95% CI 1.04-1.10). Conversely, dental self-confidence (PR 0.96, 95% CI 0.93- 0.98) was negatively associated with discrimination. Conclusions The perceived psychosocial impact of dental aesthetics is associated with experiencing discrimination among outpatients from a Peruvian public hospital. We advocate for structural changes to address discrimination in healthcare spaces by corresponding governmental authorities.Acceso abierto
