INTRODUÇÃO: A avaliação sistemática das experiências das mulheres durante o parto representa uma importante estratégia para viabilizar melhorias na atenção à saúde materna e neonatal. OBJETIVOS: Adaptar o Childbirth Experience Questionnaire (CEQ) para o contexto brasileiro e determinar as propriedades psicométricas da versão em português (do Brasil), denominada CEQ-2BR. MÉTODOS: Estudo transversal com 225 puérperas recrutadas através das redes sociais. Após o consentimento informado, as participantes preencheram um formulário eletrônico, que incluía a versão preliminar da CEQ-2BR. O tratamento dos dados foi realizado através dos pacotes estatísticos SPSS e AMOS 26. A confiabilidade do CEQ-2BR foi avaliada usando o coeficiente alfa de Cronbach. Para medidas paramétricas utilizou-se o Qui-quadrado de Pearson e o T de Student e, nas medidas não-paramétricas, U de Mann Whitney. A magnitude dos coeficientes de correlação foi classificada segundo os critérios de Cohen. RESULTADOS: O CEQ-2BR demonstrou boa consistência interna para “autocapacidade”, “suporte profissional”, “segurança percebida” e “participação”, tendo sido verificado que a avaliação negativa da experiência de parto aumenta em 1,9% e 2,1%, a sintomatologia ansiosa e depressiva pós-parto, respectivamente. CONCLUSÃO: O CEQ-2BR é uma medida válida e confiável sobre experiência de parto na população brasileira, apresenta propriedades psicométricas satisfatórias, sendo recomendado inclusive para multíparas. Houve correlação entre níveis altos de ansiedade pré-natal com experiência negativa de parto. A experiência negativa de parto explica parte das sintomatologias de ansiedade e depressão pós-parto.
Diatom isotope sample preparation for palaeoenvironmental research v1
Authors: Swann George
Published: November 2022

Diatom isotopes are increasingly used in palaeoenvironmental studies in both lacustrine and marine settings, enabling the reconstruction of a range of variables including temperature, precipitation, salinity, glacial discharge, carbon dynamics and biogeochemical cycling. This protocol details an optimised methodology for extracting diatoms for isotope analysis from sediment samples, using a range of chemical and density separation techniques that minimise sample loss and avoids the need for expensive equipment. Whilst designed for the extraction of diatoms for oxygen, silicon and carbon isotope analysis, additional stages are outlined for the analysis of other isotopes that are of increasing interest to the palaeo community (e.g., boron and zinc). The protocol also includes procedures for assessing sample purity, to ensure that analysed samples produce robust palaeoenvironmental reconstruction. Overall, the method aims to improve the quality of palaeoenvironmental research derived from diatom isotope analyses, by maximising sample purity and the efficiency of the extraction process.

This protocol designed to assess the COVID-19 booster vaccine acceptance and identify the multi-dimensional potential factors influencing booster dose acceptance among the people in Bangladesh.Bangladeshi people of age 18 years and above were the participants for this analysis. To confirm the study reliability and rationalize the research objectives, we have collected the data from eight divisions in Bangladesh. An anonymous, multi-items, and closed-ended questionnaire was adopted from the theoretical analysis of the recent literature's on topic. A quantitative approach was used to analyze data from randomly selected people between August 2022─September 2022, which resulted in the participation of 607 respondents. As the response variable of the study, we measured willingness to uptake a booster vaccine and the responses were measured as a binary variable (1=Yes, 0=No). Binary logistic regression was employed to assess the study objectives. p<0.05 was considered the significant cut-point value. A face-to-face data collection denied the acceptance of incomplete survey response, thus, no missing data received.

Diakhir tahun 2019 terjadi kejadian yang mengejutkan seluruh penduduk dunia, yaitu menyebarnya virus baru pnemunia corona (COVID-19) dengan sangat cepat ke seluruh dunia. Di beberapa negara yang terdampak COVID-19, seperti China, Inggris, Italia, Spanyol, Prancis, , Malaysia dan Filiphina telah menerapkan status lockdown secara menyeluruh. Studi ini ingin mengembalikan analisa lockdown atau tidak, berdasarkan dasar-dasar  teori ekonomi yang dikembangkan, agar analisa yang dilakukan oleh para pengambil kebijakan lebih mendasar dan fundamental. Penelitian ini masih sangat awal, karena wabah baru terjadi di akhir 2019 sehingga metodologi yang dilakukan adalah dengan metode kualitatif berupa literature review. Perdebatan terhadap kebijakan dikotomi antara lockdown atau tidak lockdown sangatlah menyesatkan jika tidak direncanakan secara hati-hati. Kebijakan lockdown ini hanya merupakan kebijakan “antara” dalam mencegah virus COVID-19 lebih meluas penyebarannya.

For a Muslim society, a mosque is very important as a place for worshipping the god as well as for social activities. Mosque has a variety of functions including ensuring a better understanding of Islam in the society and ensuring unity among the local community, including the non-muslim community. Therefore, it is important for any development of a mosque to take into account the sustainability aspect of the building which has great impacts on social, environmental, and economic factors. The objective of this study is to complete an initial study that discusses the sustainability of heritage mosques in the Malacca City Center. One of the main focuses is the green approaches. The study is still in its early stage, where a case study investigation was completed on two oldest mosques in Melaka City, namely, Kampung Hulu Mosque and Kampung Kling Mosque. This initial study focuses on the roles of the mosques on the locals in the aspects of social, environmental and economic. This study also discusses the history and architecture of the mosques. The findings of the study show that the Kampung Hulu Mosque and the Kampung Kling Mosque should be used as examples of a sustainable religious building that covers all aspects, namely economic, social and environmental aspects. This study reveals the sustainability approach of the mosques, and it also proves the role of the mosque is very important in community development. The sustainable design of these heritage mosques can be used as an example and guide to the construction of modern mosques.

Daylighting plays a crucial role in making the lecture room comfortable, particularly in terms of vision. Additionally, by lowering reliance on artificial lighting, it eases the load of electricity use. However, windows made of transparent glass let most of the sunlight inside, which degrades the visual clarity and causes glare. Therefore, strategies for limiting daylighting entry are crucial to solving the issue. One of the techniques is the use of window overhangs, including egg-crate, horizontal, and vertical forms. However, the utilisation of solely horizontal types of overhang is the exclusive subject of this study. In this study, the lighting in existing lecture room was analysed, and the impact of projections on the quality of lighting in lecture room was also looked at. This study employed the lecture room at the Faculty of Engineering and Built Environment (FKAB) known as the Seminar Room as a case study. The space is typically utilised for giving lectures as part of educational activities. Field measurements and simulations with Sefaira software were the methods employed for data collecting. By contrasting data from the simulations and field observations, the simulation software was also validated. According to the study, lecture room in the FKAB Administration Building are less successful when using a single horizontal window overhang. It is possible to contribute to a more sustainable building design with better daylight discoveries, especially for learning and teaching, by researching the most efficient horizontal projection ratio.
La técnica en la pintura contemporánea. ¿Una cuestión de género?
Authors: Andrés Fernández María Isabel
Published: November 2022

Hasta el S XIX, la exclusión de las mujeres de la enseñanza académica oficial de las bellas artes, al mismo tiempo que se les reservaba la práctica de técnicas artesanales y aptas para el entorno doméstico, provocó que ciertas técnicas y estilos pasaran a ser consideradas como más propios de un género o de otro. Diferentes corrientes artísticas feministas han reivindicado o negado la existencia de una particular sensibilidad femenina más afín a determinados medios y estilos. Este artículo parte de la hipótesis de que en el contexto occidental contemporáneo la educación y el entorno cultural son más determinantes en el estilo y técnica de un artista que una supuesta predisposición biológica ligada al género. Para comprobar esta hipótesis, se analiza el uso de la técnica de la acuarela en la obra de Marlene Dumas y de la pintura al óleo en Jenny Saville, comparando su producción con la de otros artistas varones de similares características.

It is proved that the introduction of the postnonclassical concept of point into scientific circulation will allow a deeper understanding of the essence of Genesis, change science and civilization as a whole. It was revealed that the point is, of course, an infinite fractal of the universe and space. It has been established that the external connections of the point form the physical cosmos, and the internal ones form the extraphysical reality. An interpretation of the geometric concepts of the structural elements of space is given (the complex point Kantors axiom, 1872). A new version of the concept of friedmons is presented. New ideas about space and time, the form and structure of the universe have been developed. The mechanism of entry of mankind into the world of four dimensions is revealed.
RECORDING THE FACTS: HENRY DE LA BECHE’S MAPS AS DATA REPOSITORIES
Authors: CLARY RENEE M.
Published: November 2022

As a young man, Henry Thomas De la Beche (1796–1855) participated in geology within elite gentlemanly societies. On field excursions—within England and beyond—he examined the natural landscape and recorded his observations in both narratives and illustrations. The origin of De la Beche’s geologic maps can be traced to 1821, when he mapped coastal France from St. Vaast to Fecamp; in 1822 he mapped south Pembrokeshire, Wales, using the recently published Ordnance maps (1:63,360). Of utmost importance to De la Beche was an accurate recording of factual observations in graphic form so that the maps would represent useful data in the future. De la Beche continued mapping in Jamaica (1824) and Devon’s Tor and Babbacombe bays (1827). In 1832, while mapping Devonshire, De la Beche’s personal finances worsened. He successfully petitioned the government to continue his mapping projects, proposing that his completed maps would be of national practical utility. Following the completed Devonshire maps, De la Beche leveraged the project to continue mapping other parts of the country. He became the first director of what would eventually develop into the British Geological Survey. In this position, De la Beche influenced mapping techniques while insisting upon consistency of results. Several men learned geological surveying under De la Beche and brought his methods to other countries. Since De la Beche selectively documented the geology he deemed important to observe, his geological maps serve as graphic data repositories of observations recorded during their construction. His surveying techniques also have enduring influence.
Tensor Network Model of Logistics System
Authors: Petrov A.E.
Published: November 2022

The goal is to create a network model of logistics that ensures the distribution of product flows from producers to consumers in conditions of growing volumes of information, changing economic ties. To create a model, a tensor method of calculating processes is used when changing the structure of network models of technical and economic systems, including decomposition and calculation in parts. The network is considered as a tensor, the projections of which are various connections of branches. The coordinates in the network space are closed and open paths. When changing the network structure, a new solution is obtained using a path transformation matrix. As a result, for the first time, a network model of logistics was created with branches of producers, consumers (determine the basis of open paths) and routes (determine the basis of closed paths). The resistances of the branches set the tariffs for the storage and transportation of products. The product flows of producers and consumers are set by voltage sources that create part of the distribution of flows along routes. To supplement up to full product flows, voltage sources are introduced in the branches of the routes, which give additional currents. For routes in excess of the number of open paths, the values of the complement currents should be selected. The sum of currents from all sources gives the values of product flows from suppliers to consumers, solving the logistics task. The network model is used to calculate product flows along routes without iterations, the cost of transportation, as well as to transform the solution when routes, tariffs, supply and demand change, using algorithms of the tensor method of dual networks.
On the Experience of Developing a Mobile Complex for Recording the Brain Electrical Activity on the Meringue of Dry Electrode Technology
Authors: Yuryev G.A. , Kuravsky L.S. , Yuryeva N.E.
Published: November 2022

The technology of creating a mobile complex for registration of the brain electrical activity, for recording an electroencephalographic signal with one channel, is considered. Previously, technological problems associated with insufficient sensitivity and selectivity in the sense of signal-to-noise ratio did not allow the use of electroencephalographic activity recording systems based on the so-called dry electrodes in practical applications. At the same time, even with a small number of leads, such signals, when recorded, for example, from the visual cortex localized in the occipital region of the brain can be extremely informative in the context of the operator activity analysis and other types of human activity, in which arbitrary control of attention plays an essential role. This paper considers the experience of creating a mobile autonomous complex for recording such signals for the tasks of monitoring the characteristics of the operator's activities in scientific applications. The design features of such a device, created based on Node MCU technology, which is gaining wide distribution in embedded systems, proprietary narrowband amplifiers of the electric signal and dry electrodes created by industry in the last decade, are described. Some examples of practical application of such a complex are given. The most promising directions for the development of technology are discussed.

Results of Shoulder Adhesive Capsulitis Treatment With the Use of Platelet Rich Plasma and Nucleotide Drugs: A Comparative Study
Authors: Lychagin Alexey V. , Bogatov Viktor B. , Tselishcheva Evgeniya Yu. , Muzychenkov Alexey V.
Published: November 2022

Background. Intra-articular injections of autologous platelet-rich plasma (PRP), which is a natural biological stimulant and affects various parts of the regenerative process, are often used in the treatment of adhesive capsulitis. Another line of using the reparative potential of biopolymers is the application of polynucleotides (PN), which, due to their effect on fibroblasts, are able to stimulate regeneration processes during adhesive capsulitis.
Aim of study. To evaluate the clinical efficacy of intra-articular injections of autologous platelet-rich plasma and a polynucleotide-based drug in the complex therapy of shoulder adhesive capsulitis, depending on the stage of the disease.
Methods. Performed prospective cohort study included 42 patients aged 47 to 60 years with the diagnosis of adhesive capsulitis. The duration of the disease varied from 3 months to 5 years. The patients were divided into 2 groups depending on the stage of the disease at the time of the treatment: 24 patients with the first stage of the disease (group AC1) and 18 patients with the second stage (AC2). Each group was divided into 2 subgroups of patients. In subgroups either PRP or PN were administered. The results were assessed 1 week, 1 month, 3 months after the start of the treatment. Evaluation of pain management efficacy was carried out using the visual-analog scale (VAS). The change in the quality of life of patients and the function of the shoulder joint were defined using the DASH questionnaire for assessing the function of the upper limb and the Simple Shoulder Test (SST).
Results. The use of PRP made it possible to achieve pain relief regardless of the stage of the disease. Patients of the AC1 group had a progressive pain syndrome attenuation from 80 to 45 points according to the VAS scale during the first 7 days after the start of the treatment. On the contrary, patients of the AC2 group had a slight pain increase by the end of the 1st week, that was associated with growing physical activity of patients. In the group of patients treated with PN, all experienced pain regression after the first injection. 20% of patients had pain relief within 24-36 hours after the start of the treatment., Increased joint pain was registered in 2 (10%) patients, which passed spontaneously during the first day. Pain syndrome intensity decreased in patients with both stages of the disease. According to the VAS, it decreased from 90-80 to 65 points after the first injection within 4 days in the AC1 group. Patients of the AC2 group did not notice significant effect after the first injection. The second injection reduced the pain to 65-70 points.
Conclusion. The effectiveness of PN-based drugs had no statistically significant difference from that of PRP, but their effect was achieved faster.
Comparative Biomechanical Analysis of Ankle Arthrodesis Techniques: Experimental Study
Authors: Khominets Vladimir V. , Mikhailov Sergey V. , Zhumagaziev Sayan E. , Shchukin Alexey V. , Ivanov Dmitry V.
Published: November 2022

Background. Despite the existing significant number of various techniques for ankle arthrodesis, a number of authors point to certain technical difficulties of these operations, the loss of the talus and tibia position during ankylosing, nonunion. The problem of the ankle arthrodesis technique improving requires new solutions.
The aim of the study was to compare the stability of various fixation systems in ankle arthrodesis by the finite element method.
Methods. The finite element method was used to evaluate the biomechanical characteristics of three variants of ankle arthrodesis systems: three cancellous screws, the originally designed plate combined with two cancellous screws, when the screw in the proximal plates hole is cortical, and the same plate combined with two cancellous screws, when the screw in the proximal plates hole with angular stability. The stresses and strains under the application of various types of loads are studied.
Results. In the anterior plate ankle fixation model combined with two cancellous screws and a proximal cortical screw, the implants and the talus experienced the least stresses compared to the other two models. Thus, the maximum equivalent stress in implants in the second variant was 68-124 MPa, in the first variant 92-147 MPa, in the third variant 130-331 MPa. The equivalent stress in the talus in the second version of fixation ranged from 20 to 46 MPa, in the first and third versions 28-58 MPa and 47-65 MPa, respectively. The indicators of maximum contact pressure at the border of the tibia and talus turned out to be the highest in the first variant compared to the other two models (34 MPa, 31 MPa and 31 MPa, respectively).
Conclusions. Among the studied ankle fixation systems for arthrodesis, an anterior plate combined with two cancellous screws and a proximal cortical screw is the most preferable in terms of biomechanics.
Two-Dimensional Empirical Rupture Simulation: Examples and Applications to Seismic Hazard for the Kaikōura Region, New Zealand
Authors: Walsh Ethan , Stahl Tim , Howell Andrew , Robinson Tom
Published: November 2022

Multifault earthquakes present a significant challenge to seismic hazard assessment. Historical surface rupturing earthquakes provide empirical constraints on the physical variables that control rupture length and the occurrence of multifault earthquakes. Here, we develop a rupture simulation that uses relationships derived from surface rupture databases to characterize different rupture pathways initiating on a seed fault. This empirical rupture simulator uses step distance, number of steps, angular change, and kinematic change variables to compute a combined co-rupture probability for all fault section connections within 10 km of the seed fault and subsequent active ends of the propagating rupture. Ruptures end when all possible active ends fail to pass to the next section and the next iteration begins. We applied our model to two seed faults in the region of the 2016 Kaikōura (New Zealand) earthquake and compared the results to independent constraints on paleoseismic magnitude, rupture segmentation, and global estimates of rupture complexity. Rupture set characteristics change dramatically based on seed fault location and indicate some support for geologically defined rupture segmentation. Length-based magnitudes generally agree with those estimated from paleoseismic single-event displacements. Our preferred model reproduces total trace complexity of historical earthquake catalogs and rarely generates events involving faults that ruptured in the Kaikōura earthquake. This approach may be useful for filtering or weighting scenarios in earthquake rupture forecasts. Alternatively, it could be used as a straightforward tool for directly estimating maximum likely magnitudes. Further developments incorporating slip rate-based seeding might allow results to be compared with other established methods of rupture simulation.

Se evaluó la eficiencia del biodigestor estándar de 600 litros, así como la adición de 1 litro, 10 litros y 100 litros de consorcios microbianos denominados probióticos sobre 13 muestras de agua residual domestica rural tratada en biodigestores en el Anexo Santeño perteneciente al Sector el Carmen del distrito de Tumán. Luego de la activación de los probióticos se adicionó determinadas concentraciones de los microorganismos. la microbiológica se determinó al inicio del experimento y transcurridas 24, 48 y 96 horas. En la calidad Microbiológica se determinaron las concentraciones de Coliformes Termotolerantes por la técnica del NMP/100mL, Se concluyó que 1. El biodigestor estándar no realiza un tratamiento eficiente en la calidad microbiológica del agua residual domestica rural, debido a que el valor del NMP ≥ 2400/100mL de las coliformes termotolerantes se encuentran por encima de los límites máximos permisibles fijados por el DS 004-2017-MINAM. 2. El efecto más notable es la adición de 100 litros de consorcios microbianos denominados probióticos, permitió obtener agua residual domestica de mejor calidad microbiológica, logró reducir las coliformes termotolerantes hasta NMP=150/100mL, valor que se encuentra por debajo de los Límites Máximos permisibles según el DS 004-2017-MINAM. 3. El tiempo de infiltración para el
descenso de 1 cm de lámina de agua es de 5 minutos, clasificándose según la norma I.S.020 (tanques sépticos) en un terreno de clase media.

El presente trabajo aborda el estado del arte y el piloto realizado en la ciudad de Bogotá con la ayuda de la fundación “Una Mirada al Cielo”, como una primera fase de un macroproyecto dentro del cual tiene como uno de sus objetivos establecer estrategias para la creación de escenarios de paz en mujeres víctimas del conflicto armado en Colombia. Mediante una tecnología mixta se logra establecer que dentro de la categoría de análisis de construcción de paz se debe incluir la justicia transicional, emprendimiento, mientras que la categoría de las afectaciones en las mujeres a partir del conflicto armado se debe incluir: el Proyecto de vida, la salud, la familia, las relaciones de género e Impunidad. En cuanto a la prueba piloto permite identificar que el 60% de las mujeres encuestadas son madres cabeza de familia, el 75% son emprendedoras, quienes desarrollan estos proyectos por: necesidad de obtener ingresos extra, desempleo y crecer profesionalmente. Es así como el emprendimiento puede ser una alternativa articulada a políticas y estrategias para el fomento del trabajo con enfoque de género, como un aporte a la construcción de escenarios de paz y al logro de algunos de los Objetivos de Desarrollo Sostenible como el cinco (5): Igualdad de Género, el ocho (8): Trabajo Decente y Crecimiento Económico y el dieciséis (16): Paz, Justicia e Instituciones Sólidas, entre otros.

No se busca inferenciar con la muestra por ser este estudio de nivel exploratorio. El método fue observacional, con enfoque cualitativo, el muestreo fue por bola de nieve, la variable investigada fue las actitudes sociales que se divide en actitudes sociales adaptativas y no adaptativas; y se hizo análisis categórico con gráficos, mapas conceptuales y tablas, como lo fue en parte con el software de Atlas.ti para hacer las nubes de palabras. Como actitudes sociales adaptativas tenemos que los entrevistados conocieron información del COVID-19 para aplicarlo y cuidarse, se cumplió el uso de mascarilla y el distanciamiento social en el vecindario, la gente se proyectó con ideas para su economía y su familia, y los valores morales practicados fueron solidaridad, respeto y paciencia en el hogar. Como resultados también se obtuvo que las actitudes sociales no adaptativas consistieron que los entrevistados utilizaron más el smartphone y las redes sociales como deshumanización en el hogar y vecindario, y se cree que no se vivió con tranquilidad, alegría y felicidad en la familia.
