Artificial Neural Network and ESPRIT-TLS Combination-Based Approach for Fault Bearing Recognition in Induction Machines
Authors: Dore Pascal , Chakkor Saad , Baghouri Mostafa , El Oualkadi Ahmed
Published: May 2023

Several studies have been conducted in recent decades on the detection of bearing faults to develop methods for real-time monitoring. Faults are found in almost all electromechanical systems and the major cause of damage to machinery, resulting in serious accidents to humans and material environments. While methods such as MCSA (Motor Current Signature Analysis) and PCA (Principal Component Analysis) have been widely used for obtaining and analyzing the machine's stator current and reducing its dimensions and noise, they do not allow for easier detection and parameter estimation when a defect appears, and sometimes help from an expert is needed to explain the signals. In this paper, the use of ANN-GA (Artificial Neural Networks-Genetic Algorithm) is investigated in combination with the best variant of the ESPRIT (Estimation of Signal Parameters via Rotational Invariant Techniques) method applied on stator current signals for efficient real-time bearing fault detection, to avoid any help being required from experts. MATLAB simulations of these variants revealed that the TLS variant highly discriminates the fault. By using this variant to prepare the data in the search of the best ANN model, in combination with genetic algorithms (used for optimizing the search of ANN parameters), two architectures capable of discriminating this bearing fault in real time in time and frequency domain were obtained.
Simple and Fast Voltage Disturbance Detection and Voltage Reference Generation Approach for Dynamic Voltage Restorer (DVR) to Compensate Unbalanced Voltage Sag and Swell in Three-Phase System: Simulation and Experimental Testing
Authors: Thongsan Taweesak , Chatchanayuenyong Theerayuth
Published: May 2023

The dynamic voltage restorer (DVR) is an important device for coping with voltage sag, swell, and unbalance. However, it is a real-time mechanism and must operate as quickly as possible to protect the sensitive and critical load from supply-side voltage anomalies. Hence, fast detection of voltage disturbances and reference voltage generation is essential for the DVR. This paper proposes a simple and fast voltage disturbance detection approach based on a simple three-phase phasor diagram which is easy to implement. The controller employed for the DVR uses a sliding mode control, making the entire system robust and insensitive to system parameter variations. Three different scenarios are simulated according to arbitrarily imposed supply conditions, verified in laboratory tests using the DSP R&D controller board. The results demonstrate a simpler, faster voltage-anomaly detection process which is easier for implementation compared to the other methods in the literature. The best and worst detection times (DTs) of the proposed approach are 1 and 4 ms, respectively. It yields a rapid response, accurate compensation, and robustness in restoring the load voltage to its nominal value within two cycles.
Voltage Regulation in Excessive Penetration of Solar Rooftop Distribution System Using Battery Energy Storage System
Authors: Sokul Suwicha , Fangsuwannarak Thipwan , Chayakulkheeree Keerati
Published: May 2023

This paper presents the methodology and solutions for mitigating voltage variation under steady conditions caused by differing levels of PV penetration in low-voltage (LV) rural networks. The LV rural area of the Provincial Electricity Authority (PEA) North-East area 3 District of Thailand is used as a case study with load profiles from Geographic Information System (GIS) software. Moreover, rooftop PV power generation is calculated using recorded data on irradiation in Nakhon Ratchasima Province. DIgSILENT Power Factory software is used to simulate and analyze the quality of the proposed method by focusing on the voltage level at the end of the line or dead-end (DE) of the LV network. The results show overvoltage at the DE under the high rooftop PV penetration. The battery energy storage system (BESS) is applied to mitigate the problem of low quality. Meanwhile, the system is operated by examining load demand and rooftop PV power generation to define the state of charging and discharging conditions. The proposed method can be integrated into the algorithm of a rooftop PV system and BESS local control in the home energy management system (HEMS). The results show that the proposed method can reduce the voltage variation problem existing in the PEA standard while improving the voltage level at all DEs.

Published: May 2023

Manusia merupakan makhluk sosial yang membutuhkan interaksi dengan orang lain. Interaksi tersebut disebabkan oleh penyesuaian diri individu. Dalam rentang kehidupan manusia terdapat suatu masa yang di dalamnya manusia mengalami perubahan secara fisik, mental, maupun sosial. Masa tersebut adalah masa remaja. Pada masa remaja individu dihadapkan pada berbagai macam hal yang belum pernah dihadapi sebelumnya sehingga hal ini membutuhkan penyesuaian diri. Penyesuaian diri biasanya dipengaruhi oleh pola asuh orang tua pada individu. Ketika seseorang menempatkan dirinya sebagai orang tua biasanya ia akan merasa setiap hal yang ia inginkan adalah hal terbaik untuknya, sehingga membuat orang tua menerapkan beberapa aturan dalam hidup anak bahkan tanpa memberi anak ruang untuk berpendapat. Biasanya hal ini mengakibatkan orang tua bersikap otoriter pada anak. Penelitian ini bertujuan untuk melihat apakah terdapat hubungan antara pola asuh otoriter terhadap penyesuaian diri remaja. Responden dalam penelitian ini adalah sebanyak 80 orang yang berada pada usia remaja, metode pengumpulan data menggunakan angket/ kuesioner yang terdiri dari dua bagian, yaitu pada bagian ini berisi pernyataan yang nantinya digunakan untuk melihat bagaiamana pola asuh orang tua dna pada bagian dua terdapat pernyataan yang digunakan untuk melihat penyesuaian diri remaja. Data yang didapat diolah menggunakan SPSS dengan rumus korelasi product moment. Setelah dianalisis diperoleh nilai rhitung sebesar 0,05, sedangkan rtabel = 0,220. Sehingga 0,05 < 0,220 dan dinyatakan signifikan. Sehingga dapat disimpulkan bahwa terdapat hubungan pola asuh otoriter terhadap penyesuaian diri remaja.

Published: May 2023

Pakistani population is ranked number 3rd in the prevalence of diabetes after India and China. Its self-management has been considered a keystone for the care of the disease. It is imperative to take measures that can help diabetic patients to maintain self-management. Recent advancements in the field of information technology, such as digital applications, might help to create a platform for delivering and managing self-care interventions that would be easily accessible. Thus, this study was designed to evaluate the frequency of utilization of smartphone technology for self-care. A multi-centric, cross-sectional study was conducted. The results of the study showed that most patients use smartphones but only a few users were aware of health applications for self-care of diabetes. Most patients were using health applications for their self-management only when they are in need. In conclusion, most patients in Pakistan use smart phone but they do not utilise health care mobile applications appropriately due to the lack of awareness. Given the increasing number of patients it is essential to provide public health awareness regarding use of these applications so that patients can manage their glycaemic control at home with convenience. This will also reduce burden on health care system.

Published: May 2023

Unilateral multicystic dysplastic kidney (MCDK) is congenital anomaly which can be detected by ultrasound during antenatal period. The reported rate of MCDK ranges between 1 in 2,200 to 1 in 4,300 live births. This study was aimed to assess the determinants associated with the MCDK with follow-up until teens to evaluate the evolution of the disorder. This was an observational longitudinal study, involution degrees were observed following the baseline measurement of the size of the MCDK as documented on postnatal ultrasound, and long-term complications and renal function were also recorded.  A total of 350 patients were identified, while 90 patients fulfilled the criteria of the study and completed the study duration of 10 years. Out of which 19 (21.1%) patients reported involution of MCDK size during follow-up as complete and partial, 7 (7.7%) within first year of age, 5 (5.5%) during first 2 years and 7 (7.7%) within 4 years of age. Large-sized MCDK at the time of diagnosis is less likely to involute through the first decade of life. However, conventional treatment is rational with the absence of complications.

Desa Sanur Kauh merupakan salah satu icon wisata di Kota Denpasar yang memiliki potensi baik. Sanur memiliki pantai pasir putih, di pesisir pantai terintegrasi dengan akomodasi wisata, toko kerajinan (artshop/gallery), bar, restoran, villa, dan hotel bintang 1-5 bahkan internasional. Tentunya hal ini membuka peluang kerja bagi masyarakat setempat. Semakin banyak peluang yang dapat dikelola dengan baik tentunya akan berimbas pada pendapatan. Ketika individu memperoleh pendapatan dan memenuhi syarat administratif maka secara langsung akan menjadi Wajib Pajak. Pajak merupakan kewajiban yang tidak bisa dihindari dan bersifat memaksa. Tidak sedikit Wajib Pajak dilingkungan Desa Sanur Kauh yang masih belum memahami aspek perpajakan. Maka untuk meminimalisir pelanggaran pajak yang disebabkan oleh ketidaktahuan penting dilakukan edukasi dan pendampingan dari Perguruan Tinggi. Harapannya adalah membantu masyarakat untuk dapat memahami dan serta mampu secara mandiri dalam menghitung, menyetor, melapor kewajiban perpajakan. PKM ini dilaksanakan dengan memberikan edukasi memalui seminar dan pendampingan selama bulan Maret 2023 serta membuka bilik pelayanan selama 3 hari untuk membantu masyarakat setempat dalam hal pembuatan NPWP, pemadanan NPWP dan KTP, aktifasi EFIN dan pelaporan e-SPT Tahunan PPH Orang Pribadi. Dilaksanakan di Kantor Bendesa Desa Sanur Kauh. Namun hasilnya, kesadaran masyarakat masih sangat minim. Meskipun Aparatur Desa sudah sangat mendukung dengan melakukan berbagai sosialisasi kegiatan serta memberikan fasilitas pendukung pelaksanaan, tidak banyak Penduduk Desa Sanur yang mengikuti kegiatan, karena masih banyak warga sanur yang takut berurusan dengan pajak. Tanpa mereka ketahui bahwa memenuhi kewajiban perpajakan bukanlah opsi yang bisa mereka pilih. Namun kewajiban yang harus dipatuhi.
Model Pembelajaran Dengan Metode Team Teaching
Authors: TRISNANINGSIH Sri
Published: May 2023

Pelatihan dan pembelajaran “Team Teaching” bertujuan untuk membantu dosen dalam merencanakan dan melaksanakan proses pembelajaran dengan menggunakan metode team teaching. Metode team teaching dapat dibagi menjadi dua, yaitu team teaching penuh dan semi team teaching atau team planning. Dalam model team teaching penuh, perencanaan dan pelaksanaan pembelajaran dilaksanakan bersama-sama oleh anggota tim, sedangkan dalam semi team teaching, anggota tim membuat perencanaan bersama tetapi pelaksanaan mengajar dilakukan secara individual. Namun, hasil pengamatan di lokasi pelatihan menunjukkan bahwa sebagian besar dosen masih belum memahami proses pembelajaran dengan model team teaching. Proses pembelajaran yang menggunakan metode ini masih belum direncanakan dengan cermat dan belum dilaksanakan dengan komitmen yang tinggi. Oleh karena itu, pelatihan dan pembelajaran “Team Teaching” diharapkan dapat memberikan pemahaman yang lebih baik tentang metode pembelajaran ini, sehingga para dosen dapat merencanakan dan melaksanakan pembelajaran dengan lebih efektif. Dengan menggunakan model team teaching, dosen dapat meningkatkan kualitas pembelajaran dan menghasilkan hasil belajar yang lebih baik bagi mahasiswa. Selain itu, metode ini juga dapat membantu dosen dalam membagi tugas dan tanggung jawab dalam proses pembelajaran, sehingga dapat meningkatkan efisiensi waktu dan tenaga. Diharapkan hasil pelatihan dan pembelajaran ini dapat diimplementasikan dengan baik oleh para dosen dan membawa manfaat yang besar dalam proses pembelajaran di kampus.

The early K-type T-Tauri star, V1298 Tau (V = 10 mag, age ≈ 20–30 Myr) hosts four transiting planets with radii ranging from 4.9 to 9.6 R
⊕. The three inner planets have orbital periods of ≈8–24 days while the outer planet’s period is poorly constrained by single transits observed with K2 and the Transiting Exoplanet Survey Satellite (TESS). Planets b, c, and d are proto–sub-Neptunes that may be undergoing significant mass loss. Depending on the stellar activity and planet masses, they are expected to evolve into super-Earths/sub-Neptunes that bound the radius valley. Here we present results of a joint transit and radial velocity (RV) modeling analysis, which includes recently obtained TESS photometry and MAROON-X RV measurements. Assuming circular orbits, we obtain a low-significance (≈2σ) RV detection of planet c, implying a mass of

and a conservative 2σ upper limit of <39 M
⊕. For planets b and d, we derive 2σ upper limits of M
b < 159 M
⊕ and M
d < 41 M
⊕, respectively. For planet e, plausible discrete periods of P
e > 55.4 days are ruled out at the 3σ level while seven solutions with 43.3 < P
e/d < 55.4 are consistent with the most probable 46.768131 ± 000076 days solution within 3σ. Adopting the most probable solution yields a 2.6σ RV detection with a mass of 0.66 ± 0.26 M
Jup. Comparing the updated mass and radius constraints with planetary evolution and interior structure models shows that planets b, d, and e are consistent with predictions for young gas-rich planets and that planet c is consistent with having a water-rich core with a substantial (∼5% by mass) H2 envelope.

Using resolved optical stellar photometry from the Panchromatic Hubble Andromeda Treasury Triangulum Extended Region survey, we measured the star formation history near the position of 85 supernova remnants (SNRs) in M33. We constrained the progenitor masses for 60 of these SNRs, finding that the remaining 25 remnants had no local star formation in the last 56 Myr, consistent with core-collapse supernovae, making them potential Type Ia candidates. We then infer a progenitor mass distribution from the age distribution, assuming single star evolution. We find that the progenitor mass distribution is consistent with being drawn from a power law with an index of

Correlation between Emission-line Luminosity and Gamma-Ray Dominance in the Blazar 3C 279
Authors: Dmytriiev A. , Böttcher M. , Machipi T. O.
Published: May 2023

Despite numerous studies, the origin of the γ-ray emission from blazars is still debated, in particular whether it is produced by leptonic or hadronic processes. In this study, we are testing the leptonic scenario for the flat-spectrum radio quasar 3C 279, assuming that the γ-ray emission is generated by inverse Compton scattering of external target photons from the broad-line region (IC-BLR scenario). For this purpose we use a 10 yr data set of the source consisting of the optical spectroscopy data from the Steward Observatory blazar monitoring program and Fermi Large Area Telescope γ-ray data. We search for a possible correlation between the Compton dominance and the emission-line luminosity using the discrete correlation function analysis. As a result, we find no significant correlation between these two quantities at any time lag value, while the emission-line luminosity displays a moderate correlation with the γ-ray flux at a zero time lag. We also reveal that the optical synchrotron continuum flux shows a pronounced correlation with the γ-ray flux, and therefore we interpret these results within the leptonic IC-BLR scenario where the variations in Compton dominance are primarily induced by changes in the magnetic field, rather than in the emission-line luminosity.
A Radiative-convective Model for Terrestrial Planets with Self-consistent Patchy Clouds
Authors: Windsor James D. , Robinson Tyler D. , Kopparapu Ravi kumar , Young Amber V. , Trilling David E. , LLama Joe
Published: May 2023

Clouds are ubiquitous: they arise for every solar system planet that possesses an atmosphere and have also been suggested as a leading mechanism for obscuring spectral features in exoplanet observations. As exoplanet observations continue to improve, there is a need for efficient and general planetary climate models that appropriately handle the possible cloudy atmospheric environments that arise on these worlds. We generate a new 1D radiative-convective terrestrial planet climate model that self-consistently handles patchy clouds through a parameterized microphysical treatment of condensation and sedimentation processes. Our model is general enough to recreate Earth’s atmospheric radiative environment without overparameterization, while also maintaining a simple implementation that is applicable to a wide range of atmospheric compositions and physical planetary properties. We first validate this new 1D patchy-cloud radiative-convective climate model by comparing it to Earth thermal structure data and to existing climate and radiative-transfer tools. We produce partially clouded Earth-like climates with cloud structures that are representative of deep tropospheric convection and are adequate 1D representations of clouds within rocky planet atmospheres. After validation against Earth, we then use our partially clouded climate model and explore the potential climates of super-Earth exoplanets with secondary nitrogen-dominated atmospheres which we assume are abiotic. We also couple the partially clouded climate model to a full-physics, line-by-line radiative-transfer model and generate high-resolution spectra of simulated climates. These self-consistent climate-to-spectral models bridge the gap between climate modeling efforts and observational studies of rocky worlds.

Four major mucosal-associated chemokines, CCL25, CCL28, CXCL14, and CXCL17, play an important role in protecting mucosal surfaces from infectious pathogens. However, their role in protection against genital herpes remains to be fully explored. The CCL28 is a chemoattractant for the CCR10 receptor–expressing immune cells and is produced homeostatically in the human vaginal mucosa (VM). In this study, we investigated the role of the CCL28/CCR10 chemokine axis in mobilizing protective antiviral B and T cell subsets into the VM site of herpes infection. We report a significant increase in the frequencies of HSV-specific memory CCR10+CD44+CD8+ T cells, expressing high levels of CCR10, in herpes-infected asymptomatic (ASYMP) women compared with symptomatic women. Similarly, a significant increase in the CCL28 chemokine (a ligand of CCR10), was detected in the VM of herpes-infected ASYMP C57BL/6 mice, associated with the mobilization of high frequencies of HSV-specific effector memory CCR10+CD44+CD62L−CD8+ TEM cells and memory CCR10+B220+CD27+ B cells in the VM of HSV-infected ASYMP mice. Inversely, compared with wild-type C57BL/6 mice, the CCL28 knockout (CCL28−/−) mice (1) appeared to be more susceptible to intravaginal infection and reinfection with HSV type 2, and (2) exhibited a significant decrease in the frequencies of HSV-specific effector memory CCR10+CD44+CD62L−CD8+ TEM cells and of memory CD27+B220+ B cells in the infected VM. These findings suggest a critical role of the CCL28/CCR10 chemokine axis in the mobilization of antiviral memory B and T cells within the VM to protect against genital herpes infection and disease.

An otherwise healthy 32-year-old woman suffered from finger ischemia. An echocardiogram and CT scan revealed a mobile mass in the left ventricle that was attached to the anterior papillary muscle and did not involve the valve leaflets. The tumor was resected and histopathology confirmed it to be a papillary fibroelastoma. Our case emphasizes the significance of a comprehensive diagnostic workup for a peripheral ischemic lesion. This resulted in the discovery of an unusual intra-ventricular origin for a commonly benign tumor.
To study the effect of three different doses of dexmedetomidine as premedication on the incidence and severity of etomidate-induced myoclonus
Authors: Kaushal Ketki , Kumari Anita , Abbi Pooja , Gupta Ruchi
Published: May 2023

Background and Aims:

Etomidate, a carboxylated imidazole is a rapid-acting nonbarbiturate, nonopioid hypnotic agent that has unique hemodynamic stability, favorable toxic profile, and rapid recovery after a single dose. Myoclonus may occur when etomidate is used for induction of general anesthesia. We tested the hypothesis that premedication with different doses of dexmedetomidine reduces the incidence and severity of myoclonus as well as the side effects induced by etomidate.

Materials and Methods:

This prospective, randomized, double-blinded study was done on ninety patients undergoing elective surgical procedures who were randomly allocated into three groups for intravenous administration of premedication of 0.3 μg/kg (Group DL), 0.5 μg/kg (Group DM), and 1.0 μg/kg (Group DH) dexmedetomidine in 100 mL normal saline 10 min before induction of general anesthesia with 0.3 mg/kg etomidate. The primary outcome was to evaluate the incidence of etomidate-induced myoclonus, while the severity of etomidate-induced myoclonus and the incidence of adverse effects were taken as secondary outcomes.

Results:

The incidence of etomidate-induced myoclonus was reduced by 13.3% in Group DL, 36.7% in Group DM, and 56.7% in Group DH. The severity of myoclonus was significantly reduced in Group DH as compared to Group DL and DM (P = 0.001). Side effects such as bradycardia, hypotension, and nausea and vomiting were comparable among the three groups.

Conclusion:

Premedication with dexmedetomidine 1 μg/kg before induction of general anesthesia not only resulted in a 56.7% reduction in the incidence of etomidate-induced myoclonus but also reduced the severity of myoclonus, without inducing any significant adverse effects, as compared to other two doses.

Published: May 2023

O objetivo deste estudo foi analisar a percepção dos produtores de soja na região de Irati-PR, quanto aos custos transacionais que ocorrem na produção. A pesquisa se caracteriza como descritiva, bibliográfica, levantamento de dados e quantitativa. Os resultados obtidos apontam que os produtores de soja investigados se encontram mais atentos aos custos de transação. Nota-se que os agricultores identificaram a falha na falta de igualdade nas informações no momento de negociar, gerando dúvidas quanto aos direitos e deveres de ambas as partes em um contrato e, em consequência, a ocorrência do oportunismo. A falta de informações, quanto aos preços dos insumos, a compra de matéria-prima, as dúvidas, as incertezas que giram em torno dos contratos e as desigualdades nas informações, oneram ainda mais os custos de transação existentes na atividade agrícola de soja.

O setor hoteleiro, assim como o setor turístico, possui grande impacto na economia mundial. Sendo que o setor hoteleiro foi um dos principais atingidos no período pandêmico, este fato levantou o questionamento sobre o que viria a acontecer com os preços desses serviços, logo busca-se neste levantamento identificar qual o impacto nos preços dos meios de hospedagem turísticos diante da pandemia causada pelo COVID – 19, para tanto foi necessária uma investigação de cunho exploratória e descritiva com uma abordagem quantitativa e qualitativa. Como principal resultado verificou-se que houve uma variação dos preços durante esse período, no entanto, a proposta não é esgotar o tema, uma vez que todas as variáveis relacionadas ao impacto econômico e social da pandemia, relacionadas à formação de preços das redes de hotéis, ainda devem ser exploradas como sugestão de novas pesquisas nessa área.

Este estudo teve o objetivo de investigar as características de experimentos em Custos. Trata-se de um trabalho que, a partir de indicadores básicos de produção científica, de leis bibliométricas e de análise de especificidades dos experimentos levantou e mapeou as características de uma amostra de 11 artigos publicados em periódicos internacionais. Os resultados globais bibliométricos sugerem que as discussões do tema ficaram concentradas no período 1998-2016; os periódicos Accounting Review e Accounting Organizations and Society compõem o grupo núcleo (core) com publicações do tema; as principais palavras-chave são relacionadas a informações e julgamentos; a maior parte dos autores mais produtivos é vinculada a instituições dos países baixos. A análise de especificidades dos experimentos revelou que os trabalhos realizados implicam em manipulação das variáveis independentes e priorizam o desenho between-subjects. Os participantes selecionados são na sua grande maioria estudantes, sobretudo de pós-graduação. Não há temas de Custos que se repetem nos experimentos, sendo cada qual voltado à análise de uma dimensão específica dos custos, o que pode indicar a oportunidade de replicação de experimentos para aprofundar o conhecimento sobre a temática.

Authors: Finucci Curi Pablo , Sattler María Emilia , Matteoda Marcos Roberto
Published: May 2023

La enfermedad relacionada con IgG4 (ER-IgG4) se caracteriza por el compromiso fibrótico e infiltrado linfoplasmocitario con predominio de células IgG4 en uno o varios órganos. El fenotipo limitado a la cabeza y el cuello abarca el compromiso de las glándulas lagrimales y salivares, enfermedad orbitaria, paquimeningitis, hipofisitis, tiroiditis, mastoiditis y compromiso de senos paranasales. Las manifestaciones orbitarias pueden incluir proptosis uni o bilateral, miopatía cicatrizal de los músculos extraoculares, inflamación orbitaria y dolor que pueden simular a la oftalmopatía de Graves. La enfermedad oftálmica relacionada con IgG4 puede presentarse con compromiso de músculos extraoculares y de grasa orbitaria, y usualmente se confunde con afección orbitaria por enfermedad de Graves. Se presenta el caso de un varón de 58 años, con historia de exoftalmos bilateral de más de 15 años de evolución, en quien se arriba al diagnóstico de ER-IgG4 y cuya resonancia magnética de órbitas evidencia un patrón característico de compromiso de músculos extraoculares.

The Quilombola population has precarious living conditions and a risk of obesity. In addition, this population has been little studied in the health area, resulting in a gap in scientific evidence and a lack of policies to promote, protect, and restore health in Tocantins state. Objective: This study aimed to describe the Physical Activity Level (PAL) and body composition of a Quilombola community in the Tocantins state, Brazil. Methods: A cross-sectional study. We study 73 individuals between 10 and 81 years old. The instruments used were: Questionnaire on PAL and sedentary behavior and the International Physical Activity Questionnaire. Body composition was assessed by bioimpedance. The statistics analysis was performed using Stata software version 11.0. Results: Sedentary individuals were not found. Among children under 13 years old, 47.8% had a low PAL. The body composition, children and adolescents obtained better results 65.3% and 31.6% respectively. Conclusion: The children’s body fat indexes are within the recommendations (but the PAL is not). PAL of adolescents, adults, and the elderly is not sufficient to cause physiological adaptations in changing body fat levels. Although the Quilombola community maintains some cultural habits, complications of modern life regarding health are concerning, as they seem to be reaching these communities, leading to a lifestyle change, as observed in large cities.

La Diabetes Mellitus (DM) es un trastorno bioquímico común y generalizado que afecta a casi 400 millones de personas en todo el mundo. Es una enfermedad multiorgánica que produce graves complicaciones que pueden poner en peligro la vida. En situaciones de hipoglucemia, la capacidad de concentración y la intensidad de la actividad física pueden reducirse. Hay que establecer seminarios y actividades pedagógicas en las aulas, con la finalidad de evitar el riesgo entre el estudiantado de desarrollar esta enfermedad, que va en aumento cada vez más entre las personas sedentarias, con sobrepeso y hábitos alimentarios poco saludables. Esta investigación trata de establecer las características y factores a tener en cuenta para identificar un perfil de VOCs (Compuestos Orgánicos Volátiles) presentes en aire exhalado. Se ha llevado a cabo una revisión sistemática en base a la Declaración PRISMA por el método QUADAS-2 (Quality Assessment of Diagnostic Accuracy Studies 2). Se concluye que la principal ventaja de este enfoque muestra un método no invasivo que puede ayudar a mejorar la calidad de vida de las personas. Una estrategia prometedora para llevar a cabo el diagnóstico y seguimiento de esta enfermedad crónica. La práctica del deporte y la actividad física puede favorecer progresos a nivel terapéutico y preventivo obteniendo beneficios óptimos para la salud.

Abstract. Diabetes Mellitus (DM) is a common and widespread biochemical disorder that affects nearly 400 million people worldwide. It is a multiorgan disease that produces serious and lifethreatening complications. In situations of hypoglycaemia, the ability to concentrate and the intensity of physical activity may be reduced. It’s necessary to establish seminars and pedagogical activities in the classrooms, in order to avoid the risk among students of developing this disease, which is increasing more and more among sedentary people, overweight and unhealthy eating habits. This research tries to establish the characteristics and factors to take into account to identify a profile of VOCs (Volatile Organic Compounds) present in exhaled air. A systematic review has been carried out based on the PRISM Declaration by the QUADAS-2 (Quality Assessment of Diagnostic Accuracy Studies 2) method. It’s concluded that the main advantage of this approach shows a non invasive method that can help improve people’s quality of life. The practice of sport and physical activity can promote progress at a therapeutic and preventive level, obtaining optimal health benefits.

Los estereotipos de género corresponden a creencias de las características y de cómo se deben comportar hombres y mujeres, dando origen a los conceptos de masculinidad y femineidad. Los objetivos de la presente investigación fueron validar el Inventario de Roles Sexuales de Bem en estudiantes de diversas pedagogías de Chile y comparar los roles de género entre estudiantes de educación física y otras pedagogías. Para ello se aplicó el Inventario de Roles Sexuales de Bem a 351 estudiantes de 15 pedagogías de una universidad de Santiago de Chile. Los resultados muestran que el inventario es válido y confiable para ser aplicado en estudiantes de pedagogías. Los/as estudiantes presentan mayores puntajes de femineidad en la mayoría de las carreras evaluadas, con prevalencia de tipología indiferenciada y masculina en hombres, y andrógina e indiferenciada en mujeres. Los/as estudiantes de Educación Física poseen los niveles más altos de masculinidad entre todas las pedagogías. Se recomienda replicar esta investigación en otras universidades y en otras carreras.

Abstract. Gender stereotypes correspond to beliefs of characteristics and how men and women should behave, giving rise to the concepts of masculinity and femininity. The objectives of the present research were to validate the Bem Sexual Roles Inventory in students of various pedagogies in Chile and to compare gender roles between physical education students and other pedagogies. To this end, the Bem Sexual Roles Inventory was applied to 351 students of 15 pedagogies from a university in Santiago de Chile. The results show that the inventory is valid and reliable to be applied in students of pedagogies. Students have higher femineity scores in most of the evaluated careers, with prevalence of undifferentiated and masculine typology in men, and androgynous and undifferentiated in women. Physical Education students have the highest levels of masculinity among all pedagogies. It is recommended to replicate this research in other universities and other careers.
