Localization of the Porion Landmark in Orthodontics: A Comparison of the Efficiency of NEMO-Ceph 2020 Software between Inexperienced and Expert Operators

2023 , Loaiza Martinez, Daniela , Llerena-Velasquez S.A. , Gallegos J. , Ferrando R.

This study discusses the utility of the NEMO-Ceph 2020 software in localizing the cephalometric landmark known as the Porion point (Po) and the Frankfurt plane in orthodontics. It highlights the challenges in locating the Porion point due to anatomical variations and external factors. The use of radiographs as a diagnostic method is mentioned, along with the need for new tools to aid in locating the Porion landmark. The study employed a database of 179 teleradiographs from the "UCAM DENTAL"database, processed using NEMO-Ceph 2020® software. Inexperienced operators (4th and 5th-year dentistry students) and an expert operator participated. Linear measurements and angular differences were analyzed using the software. Results revealed discrepancies in the Porion point's location among operators, with mean discrepancies of 2.42 mm (X-axis) and 2.23 mm (Y-axis). The mean discrepancy between Porion points was 2.47 mm, and with the Frankfurt point was 2.44 mm. No statistically significant correlation existed between discrepancies in the X and Y axes. The study concluded that there was a significant difference in Porion point location between inexperienced operators and the expert, and that NEMO-Ceph 2020® software required expert operators for accurate localization of cephalometric landmarks and could not predict the point independently. © 2023 IEEE.

Methodological strategy for asynchronous learning mathematical operations with real numbers

2022 , Espinosa-Pinos C.A. , Nunez-Torres M.G. , Jordan-Buenano N. , Jordan-Buenano C.

Consolidating the skills to use concepts, properties, and procedures based on algorithms or heuristics and analysis to solve challenging situations is of great importance for students in their learning. This article aims to propose a methodological strategy based on adaptive learning to facilitate the solution of combined operations with real numbers in eighth-grade students of basic general education. The mixed method uses questionnaires applied to students and teachers to collect data. The diagnosis determines that students do not master the basic competencies to work basic operations with real numbers. The teachers agree with the need to apply innovative strategies that promote learning in mathematics. It is concluded that it is imperative to update the planning of content with activities that help motivate students to learn mathematics, considering that not everyone learns at the same pace. © 2022 IEEE.

The intervention of Brain Gym in the mathematical abilities of high-school students: A pilot study

2023 , Ramos-Galarza C. , Aymacaña-Villacreses C. , Cruz-Cárdenas J.

Introduction: The learning process of Mathematics is a challenge in Latin America; therefore, it is of vital importance to conduct actions that improve the performance in this science. Methods: This article is reporting on quasi-experimental research, where, through the use of Brain Gym, the objective is to improve: the definition of rational numbers, problem-solving ability, mathematical order relationships, and equivalent fractions. We worked with 67 students between 12 and 14 years old, organized into an experimental group (n = 35) and a control group (no participation group; n = 32). Results: We made pre and post-test measurements and found that the control group students improved in their problem-solving ability F(1,65) = 8.76, p = 0.04, η2 = 0.12 and equivalent fractions F(1,65) = 4.54, p = 0.03, η2 = 0.06. Discussion: In conclusion, the importance of applying innovative processes to improve the teaching and learning of Mathematics can be affirmed. It is important to note that both the control and experimental groups improved their learning, however, the experimental group did so to a greater extent than the students in the control group, who received a traditional educational process, and they did learn, but not at the level of the experimental group.

A comprehensive study of Ecuadorian adult patients with a mild and moderate presentation of COViD-19

2023 , González Andrade, Fabricio , Carrero Y.

Aim To characterize non-hospitalized patients with mild and moderate clinical presentation. Methods We performed an epidemiological, observational, descriptive, and cross-sectional study carried out in Ecuador, with 1,447 participants between 18 and 66 years, non-hospitalized, with a molecular RT-PCR test for SARS-CoV2. We analyzed demographic characteristics according to sex, age group, clinical findings, behavior after diagnosis, family and social behavior, sequelae, clinical evolution, type of exposure, and personal history. Results The sample analyzed had a mean age of 37 years (95% CI 18–66), women 713 individuals (49.27%), men 733 individuals (50.66%). Age group distribution was 18–30 years, 524 individuals (36.29%), 31–45, 538 individuals (37.26), and more of 45 years, 382 individuals (26.46%). 1416 individuals were mestizos (97.99%). According to the province of residence from Pichincha were 1019 patients (70.52%), followed by Imbabura, 93 patients (6.44%), and the others 335 (23.15%) patients come from all over the country. In women, the most common findings were fever >38C (54.40%), sputum (27.43%) and hypoxia (16.32%); HTN (5.75%) and hypercholesterolemia (3.69%). Men were more prevalent in all other findings. Comorbidities were more prevalent in all those over 45 years of age. COVID-19 antibodies test was positive in 416 patients (28.85%). Neuropsychiatric symptoms such as sleep disorders, generalized anxiety disorder, depressed mood, and chronic fatigue were more prevalent in men than women. Still, generalized anxiety disorder and chronic fatigue were more common in individuals of 31 to 45 years. 868 patients (60.07%) were in contact with a known infected person, 318 patients (22.02%) were health workers, and 782 patients (57.63%) were informed about work exposure. 545 patients (37.72%) were overweight, primarily women 310 (42.29%). 609 patients (42.65%) showed symptoms after the acute period, and 331 individuals (23.49%) reported some sequelae. Conclusion The epidemiological and clinical behavior of hospitalized and critical patients differs greatly from ambulatory or mild or moderate symptoms. It is essential to highlight those non-hospitalized patients constitute the predominant population of patients, hence the importance of adequate management that would directly affect the development of complicated forms and, consequently, the collapse of healthcare centers. It is vitally important to open more investigations that compare hospitalized and outpatient patients to have a clearer picture of the epidemic. Copyright: © 2023 González-Andrade, Carrero.

Validation of a Scale of Labor Skills in Crisis Situations

2023 , Guerra Guerra, Paulina

All organizations can have a crisis time, in recent years, some factors such as the pandemic, political and economic problems have shown that workers need to develop skills to manage new dynamics and create employment strategies. "The organization must have a good performance that is oriented towards the vision, mission, goals and objectives of the organization. For this we need qualified human resources, because good training and other supportive social spaces are needed to improve the quality of human resources"[1]. One of the key challenges for government organizations today is to deliver performance effectively and efficiently. Therefore, the purpose of this study is to validate the work skills scale in times of crisis, which can be used to find out the knowledge, skills, abilities and attitudes of employees to manage staff training in the future. Currently, only a few instruments allow measuring work skills during a crisis, this instrument measures orientation to results in different situations, building relationships, vision and foresight, decision-making, creativity, resilience, emotional intelligence, social networks in each question. This study validates the Competencies for Working in Crisis as a new psychometric tool. The scale was validated after collecting data from 401 SME (small and medium-sized enterprises) employees from different provinces in the Ecuador. It is a descriptive study, non-experimental and longitudinal. Factor structure, reliability and validity measures were also examined using SPSS-21 statistical procedure. Finally, for the analysis of internal consistency, Cronbach's Alpha coefficients were calculated with values (.78), which is considered acceptable [2]. © 2023 IEEE.

Body Composition Evaluation using Bioelectrical Impedance and its Impact on Academic Performance of Nursing Students

2023 , Romero Riaño, Paola , Camaño Carball, Lilian , Yánez-Rueda H. , Buele, Jorge

In the past, nutritional assessment relied on manual measurements that did not allow for the differentiation of body composition components. With technological advancements, the introduction of bioelectrical impedance has provided a more specific approach to obtaining results. This study aims to utilize this innovative method to assess the connection between body composition and academic performance in nursing students. The research focused on a representative sample of 89 participants, utilizing bioelectrical impedance to measure the primary bioelements of the human body. Strong and significant correlations were observed between height and weight, height and muscle mass, and muscle mass and weight. A moderate correlation was found between weight and fat, as well as significant weak correlations between age and fat, and between fat and body mass index. Additionally, a significant weak negative correlation was observed between height and fat. Of the participants, 42.2% of women and 48% of men were classified as overweight. However, the statistical analysis did not reveal significant correlations between academic performance and variables such as weight, muscle mass, fat, and body mass index. Based on this information, it was concluded that most students had a body mass index within the normal range, and no direct relationship between body composition and academic performance was identified. Continuous monitoring of overweight students using this technology is recommended to promote healthy nutritional practices. © 2023 IEEE.
