Authors: Cabezas Sebastian , Hegedűs György , Bencs Péter 
Published: April 2023

AbstractThe aim of the paper is to supply updated air convective coefficients by means of three empirical correlations set forth by Zukauskas, Churchill and Hilpert for cylindrical bodies in cross-flow. In this study, low Reynolds numbers and air velocities within the range of were considered, hence, sundry values of convective coefficients were obtained and applied in a lumped heat capacity model. Finite element analysis simulations were implemented, exhibiting good conformity based on these correlations. The findings show that among the three methodologies, Zukauskas's correlation presents minimum standard deviation and the maximum standard deviation is presented by Hilpert's correlation , Churchill correlation presents a standard deviation of . The results are reliable and can therefore be used for analyzing heat convection.

Published: April 2023

It is an important research area to define the bioactivities of plant fractions and to create appropriate utilization areas for them. Although Cotinus coggygria, which is widely used in folk medicine, which grows from Europe to the center of China, has a wide variety of bioactivities, there is limited information about its influence on the immune system.The anti-proliferative effects of Cotinus coggygria extract on stimulated peripheral blood mononuclear cells (PBMC) were determined by CFSE dilution method. The effects of the extract on peripheral blood T and natural killer (NK) cells were followed by their proliferative responses. Annexin V / PI staining method was used to evaluate the apoptotic effects of the extract on PBMCs. The effects of the extracts on expression levels of IL-1?, IL-2, IL-4 and IL-10 genes were investigated.Effect of Cotinus coggygria on the proliferation of T cells and NK cell subsets were decreased in a dose dependent manner. Anti-proliferative effect of Cotinus coggygria extract on stimulated PBMCs was not directly related to its apoptotic properties, it also changes the cytokine genes expression on PBMCs. Our study suggests that Cotinus coggygria methanol extract, whose anti-inflammatory effects have not been investigated yet, may be a pioneer in the identification of new molecules with anti-inflammatory properties and the development of related therapies.
Effect of operating conditions of mine monorail locomotives on the durability of drive wheel polymeric rims
Authors: Arefiev E. M. , Ryabko K. A. 
Published: April 2023

An increase in the rate of coal mining and a reduction of its prime cost can be ensured by comprehensive mechanization and automation of the system of mine auxiliary transport through the widespread introduction of overhead monorail tracks. The potential use of mine monorail tracks are conditioned by the following factors: low payload ratio of the train; reduction of the mine workings cross-section area due to transfer of auxiliary transport to the upper part of the workings; high operational safety; as well as the possibility of dismantling the track in the unused sections and subsequently installing it in new mine workings. The use of rubberized rollers in the drives of mine monorail locomotives enables the coefficient of adhesion of the wheel with the monorail to be increased. It also reduces dynamic loads and the noise level during operation. The purpose of this research is to assess the durability of polymeric rims of drive wheels for mine monorail locomotives, taking into account their operating conditions. Stress distribution over the contact area of the wheel rim with the monorail was determined, enabling the development of measures to increase the service life of drive wheels of mine monorail locomotives to be developed. It was established that the effect of the monorail track deformation has no significant impact on the durability of drive wheel rims of mine monorail locomotives. A mathematical model was obtained to determine the durability of drive wheel polymeric rims, taking into account the maximum dynamic forces arising during the contact of drive wheels with the monorail. The durability of wheel polymeric rims of mine monorail locomotives was assessed in accordance with the Bailey criterion with regard to the maximum values of dynamic contact loads arising during the monorail train movement. It was also established that an increase in the carriage mass from 20 to 47 kN leads to 32 % less durability of a monorail locomotive drive wheel rim (from 8700 to 5900 hours).
The intraoperative surgical context.
Authors: Salazar Ángela María 
Published: April 2023

Objective. To interpret the experience of being unconscious or alert from a group of patients during the surgical act and appreciations from the members of the nursing team on the same context.
Methodology. Qualitative study focusing on grounded theory. Information was collected through a) observation and b) interviews to 20 patients, 19 nursing aides, and 8 nursing professionals who work in level II surgical centers in Valle de Aburrá, Colombia.
Results. From being aware of everything to being at the mercy of another, during el intraoperative, the patient goes through different states of conscience, which means being subjected to total care. Instead, for the nursing personnel the same context implies different behavior going between two environments: the “scenario” –when in front of the patient awake, which involves measured and diplomatic behavior; or, “behind the scenes” – with the person under the effects of anesthesia – the behavior is more free and uninhibited.
Conclusion. The intraoperative surgical context is different for patients and for the nursing team. However, it is necessary to bear in mind that they are caring for a human being who requires respect, dignified treatment, and that care must be promoted under an ethical perspective.

Published: April 2023

Objective. Children’s health perception through creative drawing language the identification of external factors perceived as negative or positive to health by children.
Methodology. A descriptive study that describes the analysis of the expressive language of drawings and written comments. The sample consisted of 130 children in 3rd and 4th classes from four randomly selected schools, in the region of Central Portugal Continental (Coimbra district). The study was conducted during the first semester of 2011. The data collection was performed by means of Rodrigues’ drawing/writing sheet. This sheet is divided in 4 areas (2 of them to draw what children consider good for health and the other 2 to write the content or message of the drawings). The themes expressed are classified based on the priority areas for the promotion of healthy lifestyles.
Results. children value healthy food, physical activity, mental health, prevention of inappropriate substance consumption and health and environment. The drawings and comments show links between diet and physical exercise, and between mental health and interpersonal relationships.
Conclusion. Drawings and comments facilitate health professionals understanding of children’s perception of health positive and negative factors. The results of the study allow planning intervention strategies in school health from infant perception.

Authors: Osorio Galeano Sandra Patricia , Pulgarín Torres Ángela María , Restrepo Suarez Yolanda , Segura Cardona Ángela María 
Published: April 2023

Objective. To establish the relationship between Acute Respiratory Infection (ARI) and the practices and knowledge the child caregiver has.
Methodology. Case-control study in which cases were children hospitalized for ARI, and controls children hospitalized for other conditions. Interviews were applied to the children’s caregivers to investigate their level of knowledge and practices related to ARI.
Results. 24 cases and 24 controls were studied. The caregiver profile in both groups were women, mother of the child, housekeeper, high school level of education, members of the contributive regimen, and from socioeconomic status 2 and higher. The cases group caregivers had a lower proportion of proper IRA knowledge than controls (Cases=4.2% and controls=8.2%). Knowledge about when to consult as an emergency was proper in the 75.0% of the caregivers in the case group versus 66.7% in the control group. In the actions taken when the child has IRA, what caregivers in the control group do better is the proper management of fever, other actions had fair and poor proper management proportions.
Conclusion. Caregivers Knowledge and practices were inadequate, the necessity to implement and reinforce educative actions in the community is shown.

Authors: Ferreira Maria de Lourdes Silva Marques , Peron Giaxa Thais Erika 
Published: April 2023

Objective. To identify reasons why women look for early health care attention at the end of pregnancy.
Methodology. Qualitative study based in socio-existential phenomenology proposed by Al­fred Schütz. Nine pregnant women who consulted to the maternity service without being in real labor were interviewed.
Results. The following analysis categories emerged: Having different symptoms or signals from the ones they had felt or been informed about, not being able to identify real labor, fear to fetal complications for being close to the probable labor date, feeling calmer when being seen by professionals of the institution, lack of problem solving by other services of the health institution, fearing out of hospital delivery, imitating real labor, looking for tranquility in the idealization of labor and mo­difying behaviors to guarantee attention.
Conclusion. Women are insecure and fear because of a fragmented health care, where they do not perceive themselves linked to the prenatal control program anymore, and at the same time they don’t find the health care assistance they want.

International trends in nursing care
Authors: Salazar Maya Ángela María 
Published: April 2023

Nursing care international trends, which are changing in an unexpected pace internationally, are discussed in the article. Aging, urbanization and globalization consequences accelerate the propagation of transmissible diseases worldwide, and increase the load of chronic and degenerative diseases. Health care systems contexts, every time more complex, are concerned about increases in the sanitary expenses, disparity in the health care attention and short stance hospitalization. Health care users in the future will be mostly over 65 years old, with multisystem and chronic diagnosis, with more knowledge about health, disease and the score systems of health care providers. Nursing, health care team axis will be characterized by professionals’ scarcity in a highly technological context, in which care will be based on the interpersonal multi paradigm relationship of scientific research, with a real tendency to standard care. As a discipline, nursing will keep strengthening its body knowledge. Nursing autonomy will be of great transcendence, developing own responsibilities and assuring care management.

Authors: Rodríguez Gázquez María de los Ángeles 
Published: April 2023

Siendo la misión de Investigación y Educación en Enfermería “la divulgación de conocimientos científicos y técnicos referidos a la salud, la enfermedad y a los procesos que se relacionan con éstas, a la práctica de enfermería, y otras disciplinas de las áreas de la salud y afines”, es un compromiso que seamos el canal de intercambio de conocimientos y experiencias que en los ámbitos nacio- nal e internacional está produciendo nuestra disciplina. Para cumplir con ello, debemos enfrentar todos los días el reto de atraer a los autores para que escriban en nues tras páginas.
Por otra parte, lo que los investigadores miran cuando quieren publicar un artículo es que la Revista sea afín al área del tema y que les pueda brindar la mayor difusión a su trabajo. Un indicador muy utilizado actualmente a nivel mundial para la evaluación de la visibilidad de las revistas es el Factor de Impacto (FI), que viene siendo publicado anualmente desde 1975 por la compañía Thomson Reuters en el Journal Citation Reports® (JCR). Este indicador mide el número de veces que un artículo promedio de una revista es citado en un año en particular; a más alto FI se supone que es mayor la difusión del conocimiento.

Authors: Morales Amalia María , Schmidt Riovalle Jacqueline , García García Inmaculada 
Published: April 2023

Objective. To determine the knowledge of the Andalusian “Legislation of Rights and Guarantees of the Dignity of Individuals during the Death Process” and perception of the formation on attention to terminally ill patients by students of health sciences at Universidad de Granada, Spain.
Methodology. Cross-sectional descriptive study, conducted in 2010, with the participation of 572 students from the Nursing, Physical Therapy, and Occupational Therapy careers of the Faculty of Health Sciences at Universidad de Granada. A questionnaire including 19 variables was used. The data gathered was analyzed with the SPSS 15.0 program.
Results. Half of the participants know of this Legislation. A total of 86.7% of the students did not know that the limitation of the therapeutic effort is a legal practice throughout Spain; 97.9% did not know either that the limitation of vital support measures is a legal practice. 64.2% of the students feel capable of addressing this issue with terminally ill patients and their families. 83.3% of those surveyed report not having sufficient knowledge to provide information about the “Living testament”. Nursing students have greater knowledge of the Legislation studied; likewise, those who took the Palliative Care course obtained better results than students who did not.
Conclusion. Students do not have adequate knowledge of the Andalusian legislation of dignified death. Although the participants do not feel prepared academically to deal with these types of patients, they do consider themselves capable of doing so.
