Abstract: The aim of this work is to put forward a methodology to evaluate the oscillatory stability of a power electric system (PES) analyzing the low-frequency oscillatory modes (LFOM) through the processing of synchrophasor measurements Phasor Measurement Units (PMU) of ambient data. The proposed methodology, based on spectral and pseudo-energy analyses and on parametric methods of Canonical Correlation Analysis and Yule-Walker, estimates the LFOM, whose frequency and damping characteristics provide critical information to PES operators to carry out preventive or emergency control actions. The proposed methodology was applied to synthetic measurements for its tuning and to characterize its range and accuracy, and to PMU records of the Ecuadorian power transmission system, successfully identifying the 0.4 Hz inter-area mode of the Ecuador-Colombia interconnection. The contributions of this work are aimed at evaluating the oscillatory stability of the PES through automatic computational tool that processes PMU signals of ambient type data.

ABSTRACT Introduction/framework/objectives: The use of this equipment is increasingly common in various professional sectors and for longer periods, whether within a work shift or throughout life. Thus, their interaction with workers' health becomes increasingly relevant, resulting in the need to research what has been described on this topic. This review aims to summarize the most relevant information published, so that professionals in the Health and Safety teams have more tools to guide the matter and so that the workers themselves better understand what could be at stake and are more receptive to protective measures that may be proposed. Methodology: This is a Bibliographic Review, initiated through research carried out in april of 2023, in the databases “CINALH plus with full text, Medline with full text, Database of Abstracts of Reviews of Effects, Cochrane Central Register of Controlled Trials, Cochrane Database of Systematic Reviews, Cochrane Methodology Register, Nursing and Allied Health Collection: comprehensive, MedicLatina and RCAAP”. Content: Acoustic shock can be secondary to an intense and unexpected noise and its prevalence can vary between 13 and 22%; however, it is a complex and controversial concept. It is eventually characterized by otalgia, tinnitus, vertigo, a burning sensation near the ear and anxiety. Acoustic shocks can cause cochlear trauma. The use of Headsets does not seem to cause more fatigue than noise from other sources, as long as it is of the same intensity. Most Call Centers operators work in an open space, with colleagues, which increases exposure to noise. The higher this is, the higher the eqquipment is placed. Susceptibility to hearing loss presents individual variability and interaction with some comorbidities (such as smoking, high blood pressure, diabetes and dyslipidemia); as well as gender and age. Most of these operators listen well; even if they report difficulty in perceiving words with ambient noise and tinnitus. Discussion and Conclusions: Although it is quite common for Call Centers workers to mention, during Occupational Medicine consultations, complaints that they associate with overall noise (especially that produced by Headsets); in reality, the bibliography on the topic is scarce and not very robust. Even so, it describes some very brief instructions to try to minimize the damage and enhance the well-being, satisfaction and productivity of professionals who use this type of equipment. It would be interesting to investigate the subject a little better, better understand the national panorama and publicize this in scientific publications.

RESUMO Introdução/enquadramento/objetivos: O uso deste equipamento é cada vez mais frequente em diversos setores profissionais e por períodos mais prolongados, quer dentro de um turno de trabalho, quer ao longo da vida. Assim, a interação destes com a saúde dos trabalhadores fica cada vez mais relevante, surgindo a necessidade de pesquisar o que se tem descrito sobre este tema. Esta revisão pretende resumir o que de mais pertinente se publicou, de forma que os profissionais das equipas de Saúde e Segurança tenham mais ferramentas para orientar o assunto e para que os próprios trabalhadores percebam melhor o que poderá estar em causa e estejam mais recetivos a medidas de proteção eventualmente propostas. Metodologia: Trata-se de uma Revisão Bibliográfica, iniciada através de uma pesquisa realizada em abril de 2023 nas bases de dados “CINALH plus with full text, Medline with full text, Database of Abstracts of Reviews of Effects, Cochrane Central Register of Controlled Trials, Cochrane Database of Systematic Reviews, Cochrane Methodology Register, Nursing and Allied Health Collection: comprehensive, MedicLatina e RCAAP”. Conteúdo: O choque acústico pode ser secundário a um ruido intenso e inesperado e a sua prevalência pode variar entre 13 a 22%; contudo, trata-se de um conceito complexo e controverso. Carateriza-se eventualmente por otalgia, zumbido, vertigem, sensação de queimadura próxima ao ouvido e ansiedade. Os choques acústicos podem causar trauma coclear. O uso de Headsets não parece causar mais fadiga que ruido com outras origens, desde que com a mesma intensidade. A maioria dos operadores de Call Center trabalha em espaço aberto, com colegas, o que potencia a exposição ao ruído. Quanto mais elevado este for, mais alto é colocado o som do equipamento, para conseguir ouvir a chamada. A suscetibilidade à perda de audição apresenta variabilidade individual e interação com algumas comorbidades (como tabagismo, hipertensão arterial, diabetes e dislipidemia); bem como sexo e idade. A maioria dos operadores de Call Center ouve bem; apesar de mencionarem dificuldade em perceber as palavras com o ruído ambiente e zumbido. Discussão e Conclusões: Ainda que seja bastante frequente estes trabalhadores referirem, durante as consultas de Medicina do Trabalho, queixas que associam ao ruido global (com destaque pelo produzido pelos Headsets); na realidade, a bibliografia sobre o tema é escassa e pouco robusta. Ainda assim, nela estão descritas algumas indicações muito sumárias para tentar minorar os danos e potenciar o bem-estar, satisfação e produtividade dos profissionais que usam este tipo de equipamento. Seria interessante investigar um pouco melhor o assunto, perceber melhor o panorama nacional e divulgar tal em publicações científicas.

Abstract The present research work was carried out in Zaruma´s underground workings, a city located in the province of El Oro in the southwest of Ecuador. Zaruma is a city that has been exploited since the 1500's, the urban center sits on a swarm of veins enriched with gold, the antitechnical exploitation has caused the appearance of sinkholes on the surface of the city, with the emergency that occurred in December 2021, partial remediation was carried out corresponding to the filling of the galleries and construction of plugs in order to avoid collapses in the urban area, for the execution of the remediation work required manpower, workers who entered the s underground galleries in which carbon monoxide (CO) was detected, the objective was evaluated the health effects based on the levels of exposure to carbon monoxide. The research methodology is a non-experimental, cross-sectional, descriptive study, with a sample of fifteen workers operating inside the mine, carbon monoxide measurements were taken in the mine workings and symptomatology interviews were applied to the workers taking aspects of age and time of exposure. The results describe that the operators presented symptoms: headaches, nausea, fatigue, weakness; the severity of the symptoms is a function of time and CO concentration. It´s concluded that exposure to CO in high concentrations for a period of time causes intoxication, with headache being the most frequent symptom.

Abstract The treatment of ST-segment elevation myocardial infarction has barriers depending on the geographic region. Primary coronary angioplasty is the treatment of choice, if it is performed on time and by experienced operators. However, when it is not available, the administration of fibrinolysis and referral for rescue angioplasty, in case of negative reperfusion, is the best strategy. In the same way, coronary angioplasty, as part of a pharmacoinvasive strategy, is the best alternative when there is positive reperfusion. The development of infarct treatment networks increases the number of patients reperfused within the recommended times and improves outcomes. In Latin America, national myocardial infarction treatment programs should focus on improving outcomes, and long-term success depends on working toward defined goals and enhancing functionality, therefore programs should develop capacity to measure their performance. The following document discusses all of these alternatives and suggests opportunities for improvement.

Resumen El tratamiento del infarto agudo de miocardio con elevación del segmento ST tiene barreras dependiendo de la región geográfica. La angioplastia coronaria primaria es el tratamiento de elección, siempre y cuando sea realizada dentro de tiempo y por operadores experimentados. Sin embargo, cuando no está disponible, la administración de fibrinólisis y el envío para angioplastia de rescate, en caso de reperfusión negativa, es la mejor estrategia. De la misma manera, la angioplastia coronaria, como parte de una estrategia farmacoinvasiva, es la mejor alternativa cuando hay reperfusión positiva. El desarrollo de redes de tratamiento del infarto aumenta el número de pacientes reperfundidos dentro de los tiempos recomendados y mejora los desenlaces. En América Latina, los programas nacionales para el tratamiento del infarto deben centrarse en mejorar los resultados y el éxito a largo plazo depende de trabajar hacia objetivos definidos y obtener métricas de rendimiento, por lo tanto, estos deben desarrollar métricas para cuantificar su desempeño. El siguiente documento discute todas estas alternativas y sugiere oportunidades de mejora.

Abstract This article describes the actors, the negotiation-process and exchanges take place in judicial corruption. From a theoretical proposal in which the dynamics surround corruption scandals are different depending on the place that the court has in the Judicial Branch, in the empirical analysis the paper describes how this social phenomenon works. For this purpose, the paper focusses in an extensive study of the Ecuadorian judicial system, one of the most corrupt in Latin America, through one 121 in-depth interviews with justice operators. The findings show the existence of organized groups that promote the illegitimate exchange of resources for judicial decisions and that are not only made up of judges and prosecutors but also of lawyers who play as brokers between the citizenship and judicial actors.

Resumen Este artículo tiene como objetivo describir a los actores, los procesos de negociación y la naturaleza de los intercambios que se producen en los casos de corrupción judicial. A partir de una propuesta teórica en la que se diferencian las dinámicas que rodean a los escándalos de corrupción en función del lugar que ocupa el tribunal en la pirámide del Poder Judicial, en la parte empírica se detalla cómo opera dicho fenómeno social. Para el efecto, se recurre al estudio extensivo del sistema judicial ecuatoriano, uno de los más corruptos de América Latina, a través de 121 entrevistas en profundidad con operadores de la justicia. Los hallazgos dan cuenta de la existencia de grupos organizados que fomentan el intercambio ilegítimo de recursos por decisiones judiciales y que no se encuentran conformados únicamente por jueces y fiscales, sino también por abogados que actúan como intermediarios entre las demandas de los usuarios del servicio y los funcionarios judiciales.

Klipspruit Colliery is experiencing coal losses, which leads to a negative impact on coal production and subsequently loss in revenue. This study aimed to identify the possible causes of coal losses in the No. 4 upper and lower seams. The objectives were to identify potential sources of coal losses through a literature survey, to identify areas where the coal losses occurred, to determine factors affecting coal losses, and to identify the most cost-effective methods to reduce coal losses. Highwall losses, top-of-coal losses, and coal edge losses were identified as the major areas of coal loss at Klipspruit. These losses were mostly attributed to the drilling and blasting practises of the pre-split, interburden waste, and the coal seams. Recommendations include re-visiting the current pre-split design and the tolerances adopted for the interburden and coal seam drilling and blasting design. It is furthermore recommended that Klipspruit implement a continuous improvement plan for the drilling and blasting and refresher training for the blasting crew and operators.

We present a framework for solving the problem of functional compatibility between process control equipment in control centres at underground mines and operator capabilities. The equipment incorporates displays of current ventilation, gas, and fire hazard data, status of alarm and early warning systems, a voice communication subsystem, and facilities for recording and printing of data and reports. The layout of the existing control panel is compared with a recommended design. The basic principles of ergonomic design and arrangement of the controls and indicators, as well as ease of use, type of operations carried out with these controls, and operators' viewing angles are discussed. The objective is to improve the usability of control panels, display boards, and graphic screens so as to enhance the functioning of control centres and optimize control of technological processes in coal mines.

Resumen Introducción: La tasa de cesáreas es importante para cualquier centro de atención hospitalaria. Es un indicador de calidad utilizado en muchas publicaciones y, aunque no es una estadística vital, se ha reconocido como un indicador de la calidad de atención. Objetivo: Conocer la tasa de cesáreas en una institución utilizando los grupos de Robson. Métodos: Estudio retrospectivo de bases de datos de la maternidad. Se consideraron las variables de paridad, cesárea anterior, trabajo de parto, inducción, para poder clasificar la población según los grupos de Robson. El análisis consideró los nacimientos desde octubre del 2014 hasta junio del 2021. Resultados: Se observó una tasa de 27,9% en el periodo de estudio. El grupo 5 de Robson, que considera pacientes con una o más tasa de cesáreas, mostró una elevada tasa (68%), contribuyó con el 36% de todas las cesáreas, siendo solamente el 15% de la población. El grupo 3, de multíparas con trabajo de parto espontáneo, tuvo una tasa del 1,8%, contribuyó al 0,4% de las cesáreas, siendo el 20% de la población de estudio. Se encontró una correlación significativa entre uso de parto instrumental y menor tasa de cesáreas, al realizar análisis por operador (Spearman rho: –0,45; IC95%: –0,788 a –0,0190; p = 0,043). Conclusión: La tasa de cesáreas observada fue 27,9%, y las pacientes con cesárea anterior son un grupo donde pueden concentrarse mayores esfuerzos para bajar la tasa global. Entre los operadores, los usuarios de parto instrumental tuvieron menor proporción cesáreas.

Abstract Introduction: The cesarean section rate is important for any hospital care center. It is a quality indicator used in many publications, and although not a vital statistic, it has been recognized as an indicator of the quality of care. Objective:: To know the cesarean section rate in an institution using Robson groups. Methods: Retrospective study of maternity databases. The variables of parity, previous cesarean section, labor, induction was considered in order to classify the population according to Robson groups. The analysis considered births from October 2014 to June 2021. Results: A rate of 27.9% was observed in the study period. Robson’s group 5, which considers patients with one or more rate of cesarean sections, showed a high rate (68%), contributing to 36% of all cesarean sections, being only 15% of the population. Group 3, multiparas with spontaneous labor, had a rate of 1.8%, contributing to 0.4% of cesarean sections, making up 20% of the study population. A significant correlation was found between the use of instrumental delivery and a lower rate of cesarean sections, when analyzing by operator (Spearman rho: –0.45; IC95%: –0.788 to –0.0190; p = 0.043). Conclusion: The observed cesarean section rate was 27.9%, and patients with a previous cesarean section are a group where greater efforts can be concentrated to lower the overall rate. Among the operators, users of instrumental delivery had a lower proportion of cesarean sections.

Abstract The present paper is dedicated to the study of a first-order differential inclusion driven by time and state-dependent maximal monotone operators with integral perturbation, in the context of Hilbert spaces. Based on a fixed point method, we derive a new existence theorem for this class of differential inclusions. Then, we investigate an optimal control problem subject to such a class, by considering control maps acting in the state of the operators and the integral perturbation.

Resumen El presente artículo está dedicado al estudio de una inclusión diferencial de primer orden impulsada por operadores monótonos maximales dependiendo del tiempo y del estado con una perturbación integral, en el contexto de espacios de Hilbert. En base a un método de punto fijo, derivamos un nuevo teorema de existencia para esta clase de inclusiones diferenciales. A continuación investigamos un problema de control óptimo sujeto a dicha clase, considerando funciones de control actuando en el estado de los operadores y de la perturbación integral

As real-time air quality monitoring becomes more prevalent in US underground mines, it is important to provide the highest data reliability with the fewest possible sensors. Real-time sensors remain costly, and these costs are not exclusively financial; the time required to install, calibrate, and maintain real-time sensors poses a large barrier to widespread implementation. Current atmospheric monitoring systems typically rely on displaying point-specific values. This requires operators to infer real-time airborne contamination distributions. Monitoring and control software utilizing mine ventilation network (MVN) solvers has been implemented in limited cases because of their ability to simulate ventilation systems quickly, but these solvers use a one-dimensional representation of the mine, limiting spatial resolution of estimated distributions. Computational fluid dynamics (CFD) has likewise been considered as a means to improve spatial resolution, but processing times prevent its use as a basis for monitoring and control. For the real-time monitoring of airborne contamination distributions, we propose a spatial interpolation method that can estimate the distribution of airborne contaminants in near-real time. This method provides a middle ground between fast processing times and increased spatial resolution. With the use of a pathfinding algorithm and optimization through absolute percentage error minimization, this method outperforms spatial interpolation with a Euclidean distance. By providing contamination distribution information to operators, this method and its derivatives stand to outperform current atmospheric monitoring systems.

A methodology for building pragmatic physics-based models is here adapted to predict the erosion of ladle linings in the steel industry, in order to support operators when deciding whether the lining can be used safely for another heat. A defective lining may allow 140 t of molten steel to spill, with disastrous consequences for workers and plant. The adopted work flow for the development, challenges faced, and some model results are presented. One key learning outcome is that model development should allow time for maturing the process understanding, as well as for many iterations by 'questions-responses and actions' at various stages in the model development. Good interaction between the development team and industry case owner is an important success factor. Combining or extending the model with the use of machine learning and cognition-related methods, such as knowledge graphs and self-adaptive algorithms, is discussed.
