Published: August 2022

Methicillin-resistant Staphylococcus aureus is a pathogen responsible for skin and wound infections, pneumonia, and bloodstream infections. Serious attention is needed because Methicillin-resistant S. aureus is also resistant to many other commonly used antibiotics. This study explores the potential of vinyl halogenated fatty acids as antibacterial agents. Specifically, the total synthesis of vinyl halogenated fatty acids was performed to investigate their antibacterial activity against clinical isolates of methicillin-resistant S. aureus. The novel synthesis of the vinyl halogenated fatty acids was carried out by treating either 2-dodecynoic acid or 2-hexadecynoic acid with an allyl halide and 5 mol% of bis(benzonitrile)palladium (II) chloride as catalyst. Our results demonstrate that vinyl halogenated fatty acids displayed significant antibacterial activity against clinical isolates of methicillin-resistant S. aureus and low cytotoxicity against eukaryotic Vero Cells. Moreover, it was demonstrated that vinyl brominated fatty acids could disrupt the S. aureus plasma membrane and inhibit the expression of the norB gene.

Background. Maintaining good mental health among Emergency Department healthcare workers (ED HCW) is paramount to well-functioning healthcare. We measured mental health and COVID-19 symptoms in ED HCW at a COVID-19 epicenter. Methods. A cross-sectional, convenience sample of adult (>18 years) ED HCW in Brooklyn, New York, USA, who were employed at >50% of a full-time effort, was surveyed September–December, 2020 with reference period March-May 2020. An anonymous email-distributed survey assessed gender, age, race, healthcare worker status (clinical versus non-clinical), SARS-CoV-2 testing, number of people to talk to, COVID-19-related home problems, mental health care interruption during COVID-19, loneliness, and survey date. Outcomes included symptoms of depression, psychological distress, perceived stress, post-traumatic stress disorder (PTSD), anxiety, and resilience measured using validated scales. Results. Of 774 HCW, 247 (31.9%) responded (mean age 38.2±10.8 years; 59.4% White; 52.5% men; 80.1% clinical; 61.6% SARS-CoV-2 tested). Average mental health scores were significantly higher among clinical vs non-clinical HCW (P’s<0.0001-0.019). The proportion reporting a clinically-relevant psychological distress symptom burden was higher among clinical vs non-clinical HCW (35.8% vs 13.8%, p=0.019); and suggested for depression (53.9% clinical vs 35.7% non-clinical, p=0.072); perceived stress (63.6% clinical vs 44.8% non-clinical, p=0.053); and PTSD (18.2% clinical vs 3.6% non-clinical, p=0.064). Compared to non-clinical staff, Medical Doctors and Doctors of Osteopathy reported 4.8-fold higher multivariable-adjusted odds of clinically-relevant perceived stress (95%CI 1.8-12.9, p=0.002); Emergency Medical Technicians reported 15.5-fold higher multivariable-adjusted odds of clinically-relevant PTSD (95%CI 1.6-150.4, p=0.018). Increasing age, number of COVID-19-related home problems and people to talk to, loneliness and mental health care interruption were adversely associated with mental health; being male and SARS-CoV-2 testing were beneficial. Conclusions. COVID-19-related mental health burden was high among ED HCW in Brooklyn. Mental health support services are essential for ED HCW.

Published: August 2022

Immunocompromised cancer patients are at significant risk of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection. A method to identify those patients at highest risk is needed so that prophylactic measures may be employed. Serum antibodies to SARS-CoV-2 spike protein are important markers of protection against COVID-19 disease. We evaluated total and neutralizing antibody levels pre and post third booster vaccine and compared responses among different cancer-bearing and healthy veterans. This as a prospective, single site, comparative cohort observational trial. The setting was the West Palm Beach VA Medical Center cancer center. All veterans received a third SARS-CoV-2 mRNA booster. The main outcomes were anti-SARS-CoV-2 spike IgG and neutralizing antibodies to wild-type, and B.1.617, BA1, BA2, and BA4/5 variants were measured. Disease type and therapy, COVID-19 infection, and anti-CD20 antibody treatments were documented. The third mRNA vaccine booster increased the mean blood anti-spike IgG five-fold. The second anti-spike level was equal or greater than the first in 129/140 veterans. All the groups except the myeloma group, had post-booster antibody levels significantly higher than pre-booster with 4-fold, 12-fold, 4-fold, 6-fold and 3.5-fold increases for the control, solid tumor, CLL, B cell lymphoma and all B cell malignancy cohorts. The myeloma set showed only a non-significant 1.7-fold increase. Recently anti-CD20 antibody-treated patients were shown to have approximately 200-fold less anti-S IgG production after vaccine booster than other patients. There was a 2.5-fold enhancement of wild-type virus mean neutralizing antibodies after a third mRNA booster and mean neutralization of Delta and Omicron variants increased 2.2, 6.5, 7.7, and 6.2-fold versus pre-boost levels. B cell malignancies failed to show increased post-booster neutralization. The third SARS CoV-2 booster increased total anti-spike IgG and neutralizing antibodies for most subjects. Veterans with B cell malignancies particularly myeloma and those receiving anti-CD20 monoclonal antibodies had the weakest humoral responses. Neutralizing antibody responses to Omicron variants were less than for wild-type virus. A subset of patients without humoral immunity post-booster should be considered for prophylactic antibody or close monitoring.
Transcatheter Intracerebral Laser Photobiomodulation Therapy Reduces Dementia and Cognitive Impairment in Patients with Various Stages of Alzheimer's disease
Authors: Maksimovich Ivan
Published: August 2022

Background: Alzheimer's disease (AD) is the leading neurodegenerative disease associated with dementia and cognitive impairment. A major achievement in AD treatment was the use of lasers with low output power of the red or near-infrared spectral region, which was named Photobiomodulation Therapy (PBMT). Aims: This study investigates the effect of PBMT on regression of dementia and cognitive impairment among patients with various AD stages. Methods: For the study, 97 patients with previously diagnosed AD, aged 34-80 (mean age 67.5), 34 (35.05%) men, 63 (64.95%) women, were selected. According to AD severity, the patients were subdivided: preclinical stage TDR-0 - 10 (10.31%), mild stage TDR-1 - 28 (28.87%), moderately severe stage TDR-2 - 42 (43.30%), severe stage TDR-3 - 17 (17.52%). Test Group - 48 (49.48%) patients, 17 (35.42%) men, 31 (54.58%) women, underwent Transcatheter Intracerebral Laser Photobiomodulation Therapy (PBMT). Control Group - 49 (50.32%) patients, 16 (32.65%) men, 33 (67.35%) women, underwent conservative treatment with Memantine and Rivastigmine. Results: Test Group. Due to angiogenesis and neurogenesis stimulation with Transcatheter Intracerebral Laser Photobiomodulation Therapy (PBMT), all the patients had an improvement in cerebral blood supply and microcirculation and a decrease in cerebral involutive changes. Consequently, all the patients showed reduced dementia and improved cognitive abilities. The vast majority of the patients began to correspond to the group of a milder AD stage. Control Group. No persistent expressed positive dynamics. Partial improvement was obtained only among patients with early AD stages. Conclusion: Transcatheter Intracerebral Laser Photobiomodulation Therapy (PBMT) is an effective, physiologically based method of stimulating cerebral angiogenesis and neurogenesis. As a result of such a complex impact, patients with various AD stages have cerebral capillary collateral revascularization, their tissue metabolism improves, and regenerative processes develop in the cerebral tissue. Tissue regeneration leads to an increase in the volume of the temporal and frontoparietal sections. Clinically, this leads to a stable decrease in dementia level, cognitive functions restoration, and improved quality of patients’ life. The resulting clinical effect lasts for many years. Conservative treatment with Memantine and Rivastigmine is not effective enough.

Published: August 2022

Introduction: Molecular hydrogen (H2) has emerged as a therapeutic medical gas that exerts multiple functions. H2 inhalation has been approved as safe, and some clinical studies showed that it effectively improved conditions of patients with a variety of disorders such as stroke, heart infarction, chronic obstructive pulmonary disease, cancer, and COVID-19. Urinary and fecal incontinences are unavoidable symptoms of advanced Alzheimer's disease (AD) dementia. In particular, fecal incontinence increases the level of confusion for patients and caretakers suffer from increased workloads. Materials and Methods: To assess the integrity of the neurons related to AD, the bundles of neurons passing through the hippocampus were visualized by modified diffusion tensor imaging (DTI) technology using advanced magnetic resonance imaging (MRI) Results: A 79-year-old woman with advanced AD continued to inhale 3% H2 gas containing 21% oxygen twice daily for 1 hour and maintained clinical observations for 2 years. After the long period of inhalation of H2 gas, the patient went to the bathroom by herself for adequate excretion. She remained to be able to go to the bathroom for her bowel movements in time, afterwards. After the long-term inhalation of H2 gas, her MRI of the brain to generate DTI images with an anisotropic (FA) value of 0.2 (FA = 0.2) showed improved integrity of the hippocampal neurons along with these clinical improvements. Conclusion: This case report casts the question on the current understanding that the advanced and severe AD patients will never improve.

Authors: Ferraz Lisa , Fernandes Andreia , Faustino Ana , Carvalho Simão , Pacheco Adriana , Neves Ana
Published: August 2022

Background: Although dobutamine stress echocardiography (DSE) has a high specificity, there is still a subset of patients with false positive tests (FP); whether these results have prognostic value remains unclear. Aims: To identify the clinical and echocardiographic predictors of FP on DSE and to evaluate the prognostic impact of FP on DSE. Methods: Retrospective study of 355 consecutive patients who underwent DSE for ischemia assessment over a one-year period: 134 (37,7%) women, 70,3 ± 0,57 years. Demographics, risk factors, clinical and laboratorial parameters and DSE variables were evaluated. Patients were divided into 2 groups regarding the presence (FP+) or the absence (FP0) of a FP result on DSE and a comparative analysis was performed to characterize the groups and identify potencial predictors of FP results. Patients were followed for 2 years to assess acute myocardial infarction, hospitalization for acute heart failure (HF) and mortality. Results: The FP rate was 4,5%. Comparing to FP0, patients in group FP+ were younger, baseline wall motion abnormalities were more frequent, had higher mean blood pressure values at rest and at peak stage and more often hypertensive response. There were no significant differences regarding previous coronary artery disease, medication or complete left bundle branch block. By multivariate analysis, only mean blood pressure values at rest (OR 0,01; 95%CI 0,005-0,02; p=0,003) and at peak stage (OR 0,02; 95%CI 0,000-0,004; p=0,003) were independent predictors of FP. During follow-up was observed: acute myocardial infarction (FP+: 12,5% vs FP0: 1,8%, p=0,046), HF (FP+: 6,3% vs FP0: 11,5%, p=0,44) and mortality (FP+: 6,3% vs FP0: 6,2%, p=0,65). After adjustment for age, sex and comorbidities, there were no diferences between the groups regarding HF and mortality, but the group FP+ mantained a higher rate of acute myocardial infarction (OR 0,21; 95%CI 0,065-0,354; p=0,005). Conclusion: A FP result on DSE was associated with higher mean blood pressure values during the test and with higher rates of acute myocardial infarction during follow-up. This result on DSE should therefore be faced as a risk marker for ischemic events and can identify patients that may benefit from aggressive risk factor control and careful clinical follow-up.

Published: August 2022

There is an under-addressed need to help patients who experience mild-to-moderate COVID-19 symptoms or are asymptomatic, to manage their disease at home. While no approved COVID-19 medical treatments exist for these patients, home-based self-management is crucial because it has the potential to relieve patients’ symptom burden and provide concrete actions that help mitigate anxiety, isolation and loss of personal control associated with the disease. Existing resources often provide a deluge of information, which may not be readily actionable by patients. Additionally, existing resources focus primarily on managing severe symptoms. A 4R COVID-19 toolkit was developed to address the unmet need for patients with mild or moderate COVID-19 symptoms based on expert discussions and a literature review. The toolkit applies the principles of the previously developed 4R Oncology Model of providing patients with a project plan for the course of their COVID-19 care, information on self-management of mild to moderate symptoms, and criteria for contacting their medical provider. The toolkit was developed with support from Genentech; it is not intended to substitute for the medical advice of a healthcare provider. The 4R COVID-19 toolkit continues to be improved as updated information is available via patient and clinician feedback, literature, and expert guidance. A copy of the current toolkit is attached to this paper for use and adaptation by care providers, practices, and institutions.
U.S. COVID-19 Policy: Politics Trump Science
Authors: Lepkowsky Charles
Published: August 2022

In response to COVID-19, many industrialized nations have utilized intentional, consistent strategies with demonstrated efficacy for containment of the pandemic. However, United States COVID-19 policies have been inconsistent with virology and epidemiology data. As the politics surrounding the pandemic have become increasingly contentious, they have all but neutralized efforts to contain it. The lack of media attention to the high rate of long COVID (now estimated at 20%) and the growing list of long-term health consequences (with an increasing list of neurological complications) is also a significant factor contributing to the public's misunderstanding of the disease, and poor compliance with safety protocols. Consequently, COVID-19 remains relatively uncontained in the US, which now has the dubious distinction of the highest number of COVID fatalities in world. Recommendations are made for the intentional use in the US of consistent strategies with demonstrated efficacy for pandemic containment.
Modelling the Spread of SARS-CoV2 and its variants. Comparison with Real Data. Relations that have to be Satisfied to Achieve the Total Regression of the SARS-CoV2 Infection.

Published: August 2022

A severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) ap- peared in the Chinese region of Wuhan at the end of 2019. Since then, the virus spread to other countries, including most of Europe and USA. This work provides an overview on deterministic and stochastic models that have previously been proposed by us to study the transmission dy- namics of the Coronavirus Disease 2019 (COVID-19) in Europe and USA. Briefly, we describe realistic deterministic and stochastic models for the evolution of the COVID-19 pandemic, subject to the lockdown and quar- antine measures, which take into account the time-delay for recovery or death processes. Realistic dynamic equations for the entire process are derived by adopting the so-called kinetic-type reactions approach. The lockdown and the quarantine measures are modelled by some kind of in- hibitor reactions where susceptible and infected individuals can be trapped into inactive states. The dynamics for the recovered people is obtained by accounting people who are only traced back to hospitalised infected people. To model the role of the Hospitals we take inspiration from the Michaelis-Menten’s enzyme-substrate reaction model (the so-called MM reaction) where the enzyme is associated to the available hospital beds, the substrate to the infected people, and the product to the recovered peo- ple, respectively. In other words, everything happens as if the hospitals beds act as a catalyser in the hospital recovery process. The statistical properties of the models, in particular the relevant correlation functions and the probability density functions, have duly been evaluated. We val- idate our theoretical predictions with a large series of experimental data for Italy, Germany, France, Belgium and United States, and we also compare data for Italy and Belgium with the theoretical predictions of the logistic model. We have found that our predictions are in good agreement with the real world since the onset of COVID 19, contrary to the logistics model that only applies in the first days of the pandemic. In the final part of the work, we can find the (theoretical) relationships that should be satisfied to obtain the disappearance of the virus (corresponding to a value of the effective reproduction number of the infection lower than 1).

Published: August 2022

This study examines mathematics achievement for freshmen in engineering colleges pre and post COVID-19 pandemic. For this purpose, we have compared various aspects after converting these 3 results into 100 points which were the diagnostic assessment results that conducted immediately after the admission, the mid-term and final exam results from the 1st semester at the provincial university in 2019 and 2021.
The findings are as follow; first of all, we were able to confirm the decline in scholastic ability in mathematics in 2021 as a result of the comparison in the diagnostic assessment before and after COVID-19. However, there was no statistically significant score gap on the midterm exam. On the other hand, a result of the final exam confirmed to have statistically significant higher points of post COVID-19 than pre. Secondly, according to the comparison outcome of the mathematics achievement that classified into the upper and lower-level groups using the diagnostic assessment, the final exam results declined at a statistically significant rate more than mid-term exam results for both upper-level group pre and post COVID-19. For the lower group, the final exam results had statistically significant growth compared to the mid-term in 2019, while there was no statistically significant difference in 2021. Finally, the upper groups’ aggregate results of mid & final exam were also compared, then the mathematics achievement was higher in post COVID-19 than before. And the lower groups comparison was not statistically significant gap. In conclusion, we found that online classes aggravated the gap between the upper and lower level groups in mathematics achievement. Furthermore, this indicate that the teaching methods for mathematics achievement is respectively, the online classes for upper groups, the face-to-face classes for lower groups.

Published: August 2022

The aims of this study are to derive the characteristics of a village education community operating system and to categorize its type through analyzing the system of City “A”. In order to achieve the purpose of this study, the village education community operating system of City A is analyzed, and the characteristics of the operating system are drawn by applying an analysis framework utilizing Hoy and Miskel's school social system model for the village education community operating system. As a result, the characteristics of the operating system of the village education community in City A are derived as environmental characteristics and operational characteristics, and is categorized based on the derived characteristics from the Pulppuri-Network-Modification. The action plans are as follows: firstly, it is suggested that sharing information is preceded to lay a foundation for the village education community. Secondly, personal motivation, learning culture, consultative group, and leadership must be harmonized in order to continue the operating system. Thirdly, it is important to focus on the interaction of the operating system within the relationship, rather than quantifying the characteristics of the region. This study is significant in that it recognizes the importance of the local environmental characteristics for the operation of the village education community and suggests implications for the operation of the village education community.

Published: August 2022

This study analyzed perception pattern of elementary school pre-service teachers’ response to conflict. The conclusions of this study based on the summary of the research results are as follows.
First pre-primary elementary school teachers show the same recognition pattern as: ‘compromise ❯ avoidance ❯ integration ❯ compliance ❯ competition’.
Second, looking at the perception pattern according to gender, female students are ‘less competitive’, ‘more compliant’, and ‘more evasive’ than mail students. On the other hand, they are ‘more compromising’ and ‘more integrated’.
Third, looking at the recognition pattern according to the question, there are significant differences in ‘compliance’ and ‘integration’, ‘competition’ and ‘avoidance’, ‘avoidance’ and ‘compromise’, and ‘competition’ and ‘avoidance’. Of the meaningful questions, four (15, 14, 11, 6) were based on ‘avoidance’, and one (21) was based on compromise and integration.

Published: August 2022

Introdução: O internamento do recém-nascido implica uma fonte contínua de stress para os pais. Ao adotar medidas de apoio individualizadas e em parceria com os pais, o enfermeiro potencia o desenvolvimento harmonioso e competente do recém-nascido, favorecendo o desenvolvimento das competências parentais. Materiais e métodos: Estudo quantitativo, tipo descritivo simples, com recurso à aplicação da Escala de Apoio dos Enfermeiros aos Pais, cuja validação de conteúdo para a população portuguesa, foi efetuada por Sandra Valadão em 2012. A amostra foi constituída por 100 pais de recém-nascidos internados numa Unidade de Cuidados Intensivos Neonatais de um Hospital do Norte de Portugal. Resultados: A avaliação média dos quatro domínios apresentou um resultado de 4,67. Dos quatro domínios que constituem a Escala, os pais demonstraram maior satisfação relativamente ao domínio instrumental com uma média de 4,75, seguido do domínio apreciativo com 4,73. Os domínios emocional e informativo, obtiveram resultados mais baixos, de 4,59e 4,58 respetivamente. Discussão: Os resultados obtidos vão de encontro aos resultados de Valadão de 2012, em que o domínio instrumental também foi o que obteve um maior resultado, seguido dos domínios cognitivo/apreciativo, emocional e informativo e também estão em concordância com o estudo de Tran et al. de 2009. No entanto, o domínio emocional foi o que obteve menor resultado, não indo ao encontro dos nossos resultados. Conclusão: A satisfação dos pais em relação aos cuidados de enfermagem prestados aos seus filhos é elevada, existindo áreas passíveis de melhoria de que são exemplo a comunicação estabelecida e a informação fornecida.

Published: August 2022

DC circuit breaker is the core equipment for the safe and stable operation of DC transmission system. In order to design a DC circuit breaker with low cost and current limiting function, a capacitor converter DC circuit breaker with current limiting function is proposed in this paper. The topology uses capacitance to replace IGBT to realize the switching of circuit state, which greatly reduces the number of IGBT, moreover, through the use of current limiting branch, the peak value and rate of current are restrained, the requirements of energy absorption capacity of lightning arrester are reduced, the fault cut-off time is shortened, and the cost and technical difficulty are greatly reduced. In this paper, the working principle of the extracted topology is studied and analyzed in stages, and then the parameters are designed. Finally, the system simulation model is built by using PSCAD software to verify the simulation model. Compared with the typical circuit breaker design scheme, the rationality and superiority of the proposed scheme are proved.

Authors: Yildirim Muhammed
Published: August 2022

Technological developments have led to the emergence of different platforms. Social media platforms are one of the most used platforms recently. In this study, a text-based study was conducted on fake news sharing about COVID-19 in online social networks with Shallow Learning (SL) and Deep Learning (DL) methods. In order to classify the news in the dataset, the news in the dataset is converted into a format that can be understood by the machines in the preprocessing step. In the study, the glove method was used for word representation. The document matrix obtained using the glove method was classified with the proposed hybrid model. In the proposed hybrid model, LSTM and CNN structures are used together. In addition, different Shallow Learning methods accepted in the literature were used to compare the performances of the proposed model, and the results were obtained and these results were compared with the proposed model. Among these models, the most successful results were obtained in the proposed hybrid model. When the performance evaluation metrics obtained are examined, it is obvious that the proposed model can be used to solve many other social media and network problems related to COVID-19.
IoT Based Indoor and Outdoor Localization Framework with WI-FI Fingerprinting Based on Scalable Resnet Models
Authors: Akhtar Muhammad Shoaib , Feng Tao
Published: August 2022

A scalable indoor localization technique is a vital technology for future large-scale location-aware services covering a complex of multi-story buildings. Our research on the usage of ResNet for scalable building/floor categorization and floor-level position estimation based on Wi-Fi fingerprinting is presented in this publication. Building and floor-level coordinates are estimated using our new ResNet architecture, which utilizes a stacked autoencoder to reduce feature space and a feed-forward classifier to classify multiple labels of building/floor/location. This architecture is the foundation for our multi-building and multi-floor indoor localization system based on Wi-Fi fingerprinting. On the Jaume I University (UJI) campus in Spain, we test the accuracy of building/floor estimation and floor-level coordinates estimation for three buildings with four or five stories each. ResNet-based indoor localization using a single ResNet has been proven to be feasible, with results that are close to the state of the art. One ResNet is all that is needed in order for the proposed indoor localization system based on Wi-Fi fingerprinting to function at levels close to the current state of the art, allowing it to be implemented with less complexity and less energy consumption on mobile devices.
La instalación de las fake-news como herramienta de hegemonía política en las audiencias salvadoreñas
Authors: Carballo Willian , Marroquín Parducci Amparo
Published: August 2022

Este texto es producto de una investigación de audiencias comparada realizada en 2019, antes de la pandemia, y en 2020, en plena cuarentena por COVID-19, en El Salvador. Los resultados muestran cómo, si bien los salvadoreños son capaces de nombrar que las noticias falsas −o intencionadamente falseadas− circulan en los medios de comunicación y en las redes sociales, al momento de juzgar la información estos construyen su estrategia de análisis de manera emocional y a partir de las herramientas que la vida cotidiana les proporciona. Este funcionamiento permite a las fake news no solo diseminarse, sino construir una importante hegemonía comunicacional y ponerla al servicio de intereses políticos particulares.

Los derechos étnicos en la Constitución Política colombiana de 1991: avances y desafíos en el contexto del conflicto armado
Authors: Palacios Valencia Yennesit
Published: August 2022

Desde la época de la conquista, comunidades afrodescendientes y pueblos indígenas fueron cosificadas y despojadas de sus derechos. En efecto, hasta la Constitución de 1886 eran considerados “no personas”, pero con el advenimiento del proceso constituyente, en 1991, estos grupos étnicos son reconocidos como sujetos de protección especial. Por tanto, la pretensión es reflexionar sobre los avances en el reconocimiento a los derechos étnicos en la Constitución de 1991, desde una perspectiva transversal y multidisciplinaria, integrando al estudio el contexto jurídico político que atravesó el Estado colombiano con la proliferación del conflicto armado. Epistemológicamente el estudio se fundamenta en los estudios poscoloniales para sustentar cómo pese a los avances constitucionales, raza y pobreza, estos se entrecruzan para explicar una de las secuelas arraigadas desde la conquista.
La fundamentalidad del derecho al disentimiento informado en la dispensación de las actividades sanitarias en Colombia
Authors: Puentes Araujo Mónica Alexandra
Published: August 2022

El disentimiento informado es una manifestación jurídica de oposición a cualquier tipo de terapia o aplicación de tecnología sanitaria, que en no pocas ocasiones es evadido o eludido por los agentes sanitarios, produciendo un quiebre en los derechos de los pacientes. El objetivo de este trabajo, es evidenciar que el disentimiento sanitario es un derecho fundamental, el cual, debe ser protegido y respetado tanto por el Estado como por los particulares. Para el abordaje tanto del problema como del objetivo principal, se utilizará el método descriptivo, mediante una revisión del estado de cosas, a partir de las consideraciones que ha diseñado el tribunal Constitucional Colombiano al respecto, con fundamento en la carta política de 1991. A partir de los hallazgos, se llegará a la inevitable conclusión consistente en que el disentimiento informado es un derecho fundamental que encuentra sus cimientos en la dignidad humana, la autonomía de la voluntad, el libre desarrollo de la personalidad, la integridad personal, el derecho a la información, la salud y la vida entre otros.
Modelos normativos de privacidad en las ciudades inteligentes

Published: August 2022

Las ciudades inteligentes se presentan como el futuro del desarrollo urbano, utilizando sensores, tecnologías IoT, macrodatos y servicios en nube para mejorar el nivel de vida de los ciudadanos. En este tipo de entorno los datos personales de los ciudadanos son uno de los engranajes fundamentales que permite el correcto funcionamiento de la ciudad. Aunado a esto, la empresa privada juega un rol importante en la administración de la ciudad y los datos de los ciudadanos. Sin embargo, los modelos normativos de privacidad, con su énfasis en un consentimiento informado, no están diseñados para atender los desafíos de una ciudad completamente conectada. Este artículo se enfoca en los desafíos inherentes a los modelos de privacidad tradicionales en el contexto de las ciudades inteligentes.
Repertório docente para a abordagem histórico-investigativa: um exemplo com o efeito Seebeck
Authors: Pinto José Antonio Ferreira , Santos Vinicius , Silva Ana Paula Bispo da
Published: August 2022

Este artigo teve como objetivos apresentar e discutir a construção do repertório docente por um futuro professor para a utilização da abordagem histórico-investigativa. Para isso, partiu-se do pressuposto de que a abordagem histórico-investigativa apresenta potencialidades para a melhoria do ensino de ciências ao permitir a construção de um ambiente investigativo em sala de aula, ao mesmo tempo em que oferece discussões sobre o processo de aquisição do conhecimento científico em uma perspectiva histórica. Durante a elaboração de seu trabalho de conclusão de curso em Licenciatura em Física, um futuro professor relatou em seu diário apontamentos e reflexões acerca da tentativa de reprodução de um experimento histórico e sua adaptação para uma possível sala de aula. O experimento histórico escolhido foi o correspondente ao efeito Seebeck, para o qual já havia literatura em português para consulta. Analisando seu diário à luz da concepção de reflexão crítica de Brookfield (2017), conseguiu-se identificar os três tipos de assunção no seu processo reflexivo: paradigmático, prescritivo e causal. Concluiu-se que propor e vivenciar um processo investigativo, durante sua formação inicial, auxiliou o futuro professor no desenvolvimento de habilidades e reflexões críticas, esperadas para compor o perfil de um profissional que tenha a intenção de implementar a abordagem histórico-investigativa em sala de aula.Teaching repertoire to historical-investigative approach: an example with the Seebeck’s effectThis article aimed to present and discuss the construction of the teaching repertoire by a future teacher for the use of the historical-investigative approach. For this, it was assumed that the historical-investigative approach has the potential for improving science teaching, because it allows the construction of an investigative environment in the classroom and offers discussions on the process of historically acquiring scientific knowledge. During the elaboration of his final work for the conclusion of the undergraduate course in Physics, the future teacher reported in his diary notes and reflections about the attempt to reproduce a historical experiment and its adaptation to a possible lesson plan. The historical experiment chosen was the Seebeck’s effect, for which there was already literature for consultation. Analyzing his diary in light of Brookfield’s (2017) conception of critical reflection, it was possible to identify the three types of assumption in his reflective process: paradigmatic, prescriptive, and causal. Thus, it was concluded that proposing and experiencing an investigative process, during the initial training, helped him to develop skills and critical reflections, which is expected to compose the profile of a professional who intends to implement the historicalinvestigative approach in the classroom.Keywords: Science teaching; Historical-investigative approach; Teaching repertoire.
Apertura y bidimensionalidad. El sentido ontológico de la verdad en Ser y tiempo
Authors: Domergue Tomás
Published: August 2022

Como es sabido, a lo largo de Ser y tiempo Heidegger distingue entre un sentido óntico (Entdecken) y un sentido ontológico (Erschlossenheit) de la verdad. Mientras que el primero consiste en la verdad en tanto modo en que el Dasein puede ser respecto de los entes, el segundo, por su parte, corresponde al modo en que el Dasein abre y comprende el ser de aquellos. En el presente trabajo nos enfocaremos en desarrollar la particularidad fenomenológica del segundo y su relación respecto al primero. En un primer momento, reconstruiremos la carac-terización que Heidegger hace de la verdad ontológic. Luego, nos serviremos de la asimetría entre ambos para preguntarnos por el problema de la normatividad, allí presupuesto.
La individuación spinozista bajo el prisma deleuziano: por una ética de las cantidades intensivas
Authors: Heffesse Solange
Published: August 2022

El presente trabajo pretende reconstruir la teoría de la individuación spinozista tal como Deleuze la presenta en sus obras acerca de Spinoza, vinculándola con la ontología deleuziana que se encuentra en Diferencia y repetición (su obra ontológica capital), con el fin de realizar una lectura crítica de los equívocos que se producen en torno a la noción spinozista-deleuziana de alegría. Estos últimos ocurren, por ejemplo, cuando se otorga un peso excesivo a la sucesión de las etapas en el camino de aprendizaje que conduce a la salvación spinozista, por lo que todo el planteo se reduce a una carrera finalista y acumulativa en pos de una maximización de la alegría, acumulación de pasiones alegres que es tomada como un fin en sí mismo. Considero que agrietar la presentación de “el Spinoza de Deleuze” es una de las vías que tornan posible destacar y profundizar en la pregunta por el lugar de la negatividad en la filosofía deleuziana. Esto, a su vez, nos permitirá desligarla de lecturas que pretenden hacer de ella un aliado ideológico del neoliberalismo, contribuyendo, en cambio, a la formulación de una ética de las cantidades intensivas –siendo esta la propuesta ética de Diferencia y repetición.
Hacia el origen de la intencionalidad. La búsqueda de una primigeneidad en Husserl, Henry y Marion
Authors: Marenghi Claudio
Published: August 2022

La correlación intencional de la conciencia con el mundo es el tema central de la fenomenología. Edmund Husserl ha intentado fundar esta correlación a partir de la explicitación de un curso vital previo de carácter pasivo que se orienta teleológicamente hacia actividades intencionales. En esta misma tarea, Michel Henry ha acentuado el polo de la inmanencia de la correlación, fundando la intencionalidad de la conciencia en la vida carnal afectiva. Por su parte, Jean-Luc Marion ha enfatizado el polo de la trascendencia de la correlación y ha descentrado la intencionalidad de la conciencia, atendiendo a la saturación de los fenómenos. En este trabajo nos proponemos recorrer sucintamente los tres caminos señalados en búsqueda del proto-fenómeno originario de la experiencia, intentando contrastar las propuestas y vislumbrar eventuales convergencias.
Temáticas heideggerianas en El ser y la nada de Jean-Paul Sartre
Authors: Vinolo Stéphane
Published: August 2022

La filosofía de Sartre es en gran parte heredera de la ontología de Heidegger. De hecho, es para salir de una lectura idealista de la obra de Husserl que Sartre se orientó hacía la ontología heideggeriana con el fin de establecer una ontología fenomenológica. Sin embargo, el autor muestra que, sobre los conceptos fundamentales que marcan el cruce entre ambos autores (la nada, la angustia, la muerte y la finitud), Sartre resignifica constantemente los aportes heideggerianos, lo que permite entender la ruptura fundamental entre ambos autores, ruptura según la cual, cuando la filosofía de Heidegger es una filosofía de la finitud y de la muerte, aquella de Sartre es una filosofía del infinito y de la vida.
Translation, adaptation, and validation of the Copenhagen Burnout Inventory for the Peruvian version
Authors: Hernández Breña Wilson , Burneo Andrea , Cassaretto Mónica
Published: August 2022

The goal is to adapt and analyze the psychometric properties of the Copenhagen Burnout Inventory (CBI) in workers of the national domestic violence helpline (Peru). Two measurements were taken in the same population (n=160). Translation-back translation was applied. Internal consistency was assessed with Cronbach’s alpha, corrected Item-Total Correlation and omega coefficient. Test-retest was performed in the second measurement. Convergent validity was examined with Pearson correlations with the Secondary Traumatic Stress Scale, the Perceived Stress Scale, and the Fear of Covid-19 Scale. Confirmatory Factor Analysis confirmed that the three-correlated factor model has the best fit. Regarding reliability, adequate coefficients were found (alpha: >.82, omega: >.91 and intraclass correlation: > .66). The CBI scales are correlated with the Secondary Traumatic Stress Scale, the Perceived Stress Scale, and the Fear of Covid-19 Scale, and they are also significantly associated with self-reported health status, but only work-related burnout is associated with self-reported workload. As a result, the CBI shows excellent psychometric properties.

Las tecnologías digitales han generado en los adolescentes nuevos modos de comunicación, tanto saludables como disfuncionales. El objetivo del estudio fue identificar usos frecuentes de las redes virtuales y estrategias de afrontamiento frente a usos agresivos. Participaron 243 estudiantes de contexto vulnerable de S. M. Tucumán (Argentina). Más del 70% informó usos saludables, 14% se reconoció con comportamientos de ciberagresión y 23% como cibervíctimas. Un análisis de Anova y Bonferroni mostró que este grupo refería el uso de estrategias de estilo improductivo como Autoinculparse, Hacerse ilusiones, Falta de afrontamiento, Reservarlo para sí, Preocuparse y Reducción de la tensión. Los datos confirman mayor vulnerabilidad psicológica de los adolescentes víctimas de ciberagresión para responder a situaciones de estrés.
Mediación en la enseñanza de adición y sustracción en Perú y Colombia
Authors: Santana Espitia Ana Cristina , Herrera Rojas Aura Nidia , Fajardo Santamaría Jesús Armando
Published: August 2022

Este estudio indaga tres facetas de la mediación docente: a) La sensibilidad a las necesidades del estudiante con dificultad (dificultad percibida), b) La manera de disponer actividades y experiencias que fomenten el aprendizaje y, c) La capacidad para instituir tareas con diversos niveles de complejidad (dificultad instituida). Se aplicó el Instrumento para Evaluación de Dificultad Instituida en Situaciones de Adición y Sustracción (DISAS) (Santana y Herrera, 2017) a 20 docentes peruanos y 20 docentes colombianos de 1º a 5º grado de básica primaria, quienes describieron su manera de orientar a estudiantes con dificultad para sumar y restar. Los resultados obtenidos sugieren que el entorno cultural es importante para la organización de la actividad del maestro al enseñar estas operaciones.
A visual way to represent content validity and item properties

The purpose of this instrumental study was to show how to conduct an RStudio process to obtain a content validity visual representation through the alluvial function of the ggplot2 package to Condom Use Self-Efficacy Scale (This paper explains the stages to analyze content validity using a visual representation of an interrater agreement and item – factor belonging and focused mainly on qualitative aspects to evaluate the judge’s behavior and items’ weight. Furthermore, the paper discusses classical criteria to obtain content validity and its representation. The visual representation used shows high relevance to present the qualitative data associated with the content validity analysis since it allows to visualize in a differential way the weight of the dimensions in each item, the content validity coefficient in the set of dimensions, and the behavior of the judges in the overall evaluation of the scale.
Los valores como base cognitiva del autoritarismo y la dominancia
Authors: Zubieta Elena M. , Sosa Fernanda M.
Published: August 2022

El sexismo, la xenofobia o la homofobia responden a valores y creencias sobre la desigualdad entre los grupos. Con el propósito de analizar la relación del Autoritarismo de Derecha (RWA) y la Orientación a la Dominancia Social (SDO) con los Valores (Schwartz, 1992), se realizó un estudio explicativo, no experimental transversal, sobre una muestra intencional compuesta por 407 estudiantes universitarios (58.5% mujeres; media de edad de 23.69 años). Los hallazgos ratifican al RWA y la SDO como constructos conservadores estructurados en función del poder y en valores opuestos a relaciones intergrupales no agresivas, ratificando la disposición al prejuicio generalizado. También, configuraciones diferenciales apoyan la idea del Modelo Dual de Procesamiento sobre la naturaleza multidimensional del prejuicio (Duckitt y Sibley, 2010).
