Authors: Chauhan Yashodhra , Abhichandani Roshni , Malik Saurabh
Published: August 2023

Background: Gestational diabetes mellitus increases the risk of perinatal complications and chronic diabetes in the mother and child, and early detection and treatment could improve perinatal and long-term outcomes in GDM women and their offspring. Several criteria have been proposed for diagnosing GDM, but there is no universal consensus regarding the most accurate and feasible test acceptable to every sociodemographic region. This study was undertaken to evaluate the single-step non-fasting 75 gm Diabetes in Pregnancy Study Group of India (DIPSI) criteria of GDM performed during early (16-20 weeks) mid-(24-28 weeks) late-pregnancy (32-36 weeks), compared with the two-step fasting 100 gm glucose challenge through the ACOG recommended Carpenter Coustan criteria.
Methods: It was a prospective study analyzing a cohort of pregnant women from the 16th week of gestation till the 36thth week, excluding previously known diabetic patients. All study participants were screened for GDM three times using the DIPSI criteria (between 16-20 weeks, 20-24 weeks and 32-36 weeks) and once using the 2-step ACOG criteria between 24-28 weeks.
Results: The study includes 200 participants with a mean age of 27.14% of women were diagnosed with GDM based on the 2-step ACOG recommended criteria. The sensitivity, specificity and accuracy of DIPSI criteria during 16-20 weeks were 25%, 99.4% and 78.6%, respectively; during 20-24 weeks, sensitivity was 96.4%, specificity was 95.9%, and accuracy was 96.07%. The sensitivity, specificity and accuracy of DIPSI criteria during 32-36 weeks were 96.4%, 94.8% and 95.2%, respectively.
Conclusions: DIPSI criteria is highly sensitive and specific and can accurately detect GDM between 24-28 weeks; it lacks sensitivity and is inaccurate in detecting GDM between 16-20 weeks of gestation. However, as these parameters are similar at 32-36 weeks, high-risk patients for GDM could be considered for rescreening during the third trimester.

Authors: Bindal Jyoti , Dubey Renu
Published: August 2023

Background: Menopause is universal phenomena which has adverse effect on health of women. The vaginal cytology by maturation value is an inexpensive mean to evaluate hormonal influence in women. Objective was to diagnose atrophic by vaginal pH and vaginal maturation value in peri and post-menopausal women symptomatic as well as asymptomatic.
Methods: This study conducted on 100 peri and post-menopausal women who attended in Department of Obstetrics & Gynaecology, Kamla Raja Hospital, and G.R. Medical College Gwalior from August 2015 to August 2016. They were divided into three groups: Group A (Cases) - subjects having VMV < 64 with or without symptoms, Group B (Suspects) - Symptomatic subjects with VMV > 64 and Group C (Controls) - Asymptomatic subjects with VMV > 64.
Results: The detection rate of vaginitis in total 100 peri and post-menopausal women in this study was 36% while detection rate in symptomatic peri and postmenopausal women was 36/65 i.e., 55.38%. To our surprise 13/35 (37.14%) had VMV < 64 (mild estrogen deficiency) in control group (asymptomatic postmenopausal women). They became true cases as VMV was taken as gold standard for diagnosis of vaginitis. It means that detection rate of vaginitis in asymptomatic peri and post-menopausal women were 37.14%.
Conclusions: There is a lack of awareness of symptoms and signs among both in population and physicians for early detection of vaginitis.

Published: August 2023

Sleep is a vital factor that regulates the physiology of the body in various aspects. During pregnancy, sleep problems are common. Sleep deprivation has been suggested by previous research to be associated with more adverse birth outcomes that impact both maternal and foetal outcomes. The purpose of this review is to analyse the current evidence regarding the effects of sleep deprivation during pregnancy. Quantitative studies were included and for this review, Google Scholar, PubMed and CINAHL were used to perform a literature search. A total of 38 articles were chosen for this review. Sleep deprivation may increase the risk of adverse birth outcomes in female residents due to long work hours. The initial approach to treating sleep disturbances during pregnancy is non-pharmacological. Sleep position is a major component that influences sleep quality and pregnancy outcome. Poor sleep hygiene during pregnancy can lead to a worsening of the mother, especially in the third trimester, which can have an impact on the outcome of the pregnancy. Maintaining good sleep hygiene is crucial. It has been proven by research that several non-pharmacological measures can enhance the circadian cycle. Further research with longitudinal study designs is required to examine the effect of sleep deprivation on adverse effects on the mother and foetus. Furthermore, additional research is needed to confirm the impact of sleep deprivation on the postpartum period.

A elevação artificial é feita quando o índice de produtividade de um poço se encontra baixo, visando a melhoria de escoamento de um fluido do reservatório até a superfície é aplicado um método que melhor se enquadre para a elevação das pressões neste poço, consequentemente fazendo o fluido escoar. O método de elevação artificial denominado Bombeio por Cavidade Progressiva (BCP) é o segundo mais utilizado no Brasil, isso porque é o mais indicado para a produção de óleos bastante viscosos. Nele se faz presente um motor elétrico, o qual promove a rotação para o funcionamento do sistema como um todo. Dessa forma, a implantação de energia eólica surge como o gerador de energia para esse sistema que contribui para redução de custos operacionais. Com isso, o objetivo desse estudo é avaliar o comportamento dessa inserção de energia através do software System Advisor Model.
Tuna Bulgar Devleti’nin Ticaret Politikası
Authors: TOLAN Öner
Published: August 2023

Bulgarlar, VII. yüzyılın ilk yarısında Karadeniz’in kuzey bozkırlarında Kubrat Han liderliğinde bağımsız bir devlet kurmayı başarmışlardı. Ancak kurucusunun ölümü üzerine zaafa uğrayan bu devlet kısa sürede siyasi varlığını yitirdi. Asparuh Han, kendisine bağlı boylarla birlikte Aşağı Tuna boylarına gelerek 681 yılında bir devlet kurmayı başardı. Asparuh’tan sonra gelen Tervel Han’ın başarılı idaresi döneminde devletin temelleri sağlamlaşırken hemen sonrasında yaşanan fetret dönemi merkezi otoriteyi ciddi oranda sarstı. VIII. yüzyılın sonlarında yeniden toparlanan devlet Kurum Han ile birlikte gücünün doruğuna ulaştı. IX. yüzyıl ortalarında Hıristiyan Slav bir devlet haline gelen Bulgar Devleti, Symeon döneminde siyasi gücünün ikinci zirve noktasına ulaştı. Ancak ondan sonra gelen idareciler aynı başarılı yönetimi sergileyemediler. Bulgarlar, Tuna boylarına ilk geldikleri zamandan itibaren yeni yurtlarının ekonomik potansiyelini oldukça yerinde bir biçimde değerlendirmişler ve bir takım ekonomik faaliyetlere girişmişlerdir. Bu alanda ziraat ve ticaret ilk sırada yer almıştır. Nitekim kuruluşun tamamlamasının ardından ikinci hükümdar Tervel Han döneminden itibaren aktif bir ticaret politikası uygulandığını görmekteyiz. Bu çalışmanın amacı belirtilen tarihler arasında hüküm sürmüş olan Tuna Bulgar Devleti’nin hükümdarları tarafından sürdürülen ticaret politikasının esaslarını tespit etmektir. Buna bağlı olarak, ayrı bir çalışmanın konusu olabilecek olan Bulgarlarda ticari faaliyetler konusuna girilmeyecek ve sadece devletin ekonominin bu alanına yönelik takip ettiği siyaset tespit edilmeye çalışılacaktır.

In recent times, there has been a huge demand for protein sources in a developing country such as Nigeria due to its rapidly increasing population. Poultry, from which varieties of protein sources can be derived, offers one of the major solutions to this problem. Therefore, the need for poultry farmers to put in place measures to ensure a well-controlled and conducive environment to rear birds for maximum production and efficiency arises. This work designed and developed a microcontroller-based automated regulating system to manage poultry operations effectively. The major components employed in developing the embedded system include DHT 11 sensor, Arduino UNO microcontroller with ATMEGA 328P IC chip, MQ 135 sensor, float switch, Infrared (IR) proximity sensor, buzzer, lighting (DC) bulb, 60 W AC bulb, and exhaust fans. Using relevant design models and equations, circuit designs were implemented around the Arduino UNO microcontroller, the main element of the system's control unit. A performance test was conducted on the developed system. The test results revealed that all the embedded system's key units, including power supply, lighting, sensing, display, water, and feed level control units, were fully functional, and the overall system performance was satisfactory. Apart from being suitable and efficient for small-scale farmers to rear poultry birds, the developed automated poultry regulating system could be extended to train agricultural students on the basic rudiments such as feed, water, and environmental conditions requirements in poultry bird rearing.

Authors: Subriadi Apol Pribadi , Baturohmah Habi
Published: August 2023

Changes in lifestyle have a significant impact on the development of IT services, especially transportation. Consumers easily order vehicles anywhere and anytime. Electronic word of mouth (eWOM) assists consumer decisions, but the information conveyed is less consistent and creates distrust. The COVID-19 pandemic causes company revenue to decline, even though implementation is said to be successful if it gets positive feedback and increases productivity. So, this study aims to determine the factors influencing purchase intention and customer behavior during the pandemic on ride-hailing application loyalty. The data used is 17 informants of Go-Jek, Grab, and Maxim application users. Using ewom with phenomenological qualitative methods analyzes user perceptions based on application experience. Data were analyzed using Atlas.ti software. The results show that the ewom theory is still relevant in the era of social media, especially during the pandemic. The main findings show customer loyalty consists of information quality; reviews; costs, trust; subjective norms; sentiment, emotion; satisfaction; and service quality. The new findings show the lack of influence of sentiments on customer behavior towards ride-hailing use. This study uses industry-level objects so that future research can focus on one company and evaluate the sentiment-emotion factor after the pandemic to get detailed results so that it can fully represent the existing phenomenon.

Published: August 2023

This study examines disaster response effectiveness. This workshop was preceded by a case scenario featuring an explosion in a heavily populated Kuala Lumpur City, Malaysia, produced by the researchers. The agencies involved used this case scenario as a storyline to implement the response. The coordination efforts undertaken by each agency can be seen. It is plain to see the efforts of collaboration that each agency has been putting forth. Focus group discussion served as one forum for debating the course of action taken; at the same time, the action taken by each agency involved should align with the roles and responsibilities outlined. During the workshop, it was revealed that it assisted researchers in better understanding agencies' disaster response process in identifying shortcomings, determining gaps, and improving on the processes already in place for disaster response. However, it was noted that the success of implementing SP&S lies in the involvement and participation of each agency. Therefore, it can be concluded that communication and coordination between agencies are very important in the success of an operation, not only during SP&S but also during disaster response.

Published: August 2023

Water is essential in our daily life for life purposes and other activities. Significant water quality degradation due to natural factors and human activities can harm human health and ecosystems. Therefore, water quality monitoring is always necessary for public health and a good ecosystem. This study focuses on assessing river water quality in Terengganu involving several parameters and the location of water monitoring stations along the Terengganu River, which is linked to the second-largest dam in Malaysia. This study uses multivariate analysis such as Principal Component Analysis (PCA) and Agglomerative Hierarchical Clustering (AHC) to assess water quality in the Terengganu River. PCA investigates the origin of each parameter that contributes to river pollution. Before AHC, WQI categorized monitoring stations based on different river pollution zones. The AHC method groups all water monitoring stations based on the level of river pollution zones. Then, this study was continued with the Fuzzy Decision-Making Experiment and Evaluation Laboratory (FDEMATEL) to determine the relationship between river pollution factors. The PCA results yielded five significant factors that accounted for 55.33% of the total variance. AHC classifies three clustered areas: low, medium, and high pollution. Criterion (agricultural and irrigation run-off) is the main causal relationship from FDEMATEL. The results of this study help reveal important information about river water quality in Terengganu to control pollution sources, thus helping to maintain the health of the local population and ecosystem.

Published: August 2023

Open-source programs have gained popularity due to their decentralized, quick development cycles and accessibility to everyone. Program understanding is vital for open-source software developers to modify or improve the code. However, one problem open-source developers face is the difficulty in understanding the programs as the program grows large and becomes complex. The current program understanding tool is inefficient because it only supports one programming language, while open-source programs are written in various languages. This paper discusses a new program understanding technique that facilitates multi-language program understanding. The proposed technique helps developers to understand open-source programs by supporting two unique features: multimedia and additional comments. We carried out this study in four stages. First, we examined available tools and techniques in software understanding to identify their strengths and weaknesses. Second, we proposed a new technique. Third, we designed a new tool to implement the new technique. Lastly, we evaluated the tool using a survey. We invited twenty users, including students and programmers, to use the system and ask for their feedback. The evaluation of the proposed techniques shows that the respondents have a positive perception as they agree that the technique helped them better understand the program. The multimedia support and an additional comment provided by the tool significantly improve user understanding of the program. For future work, we would like to explore the possibility of utilizing some machine-learning techniques to enhance the process of program understanding.

This study aimed to design and implement a subsurface irrigation system using porous emitters of various materials such as bubblegum, flannel, cotton, and spandex. It was carried out using descriptive methods, namely designing, measuring, observing, calculating, and analyzing data quantitatively. The results showed that the soil conductivity ranges from 1.0 to 3.01 cm3/hour, and the flannel material transmitter has a maximum hydraulic conductivity of 4.681 cm/hour. The largest and smallest porous irrigation discharges were found in flannel and bubblegum materials, with values of 2.4 l/hour and 0.59 l/hour, respectively. Emitter flannel had the best absorption capacity of 1.9348 l/hour, and the growth of porous emitter plants had the highest values of 228.6 cm, 158, 133, and 92 for height, leaves, flowers, and fruit. The daily water requirement in the vegetative phase was 112.15 ml/day, and the flowering stage continued to increase by 211.95 ml/day, while the fruiting stage was 176.63 ml/day. Tomato water requirement decreased to 156.96 ml/day at the ripening stage, and irrigation application one day after the vegetative, flowering, fruiting, and vegetative stages required 118.33 ml/day, 141.30 ml/day, 194.28 ml /day, and 264.93 mm/day, respectively. Furthermore, subsurface irrigation produced flannel optimally to meet the needs of plant growth, had no surface runoff and water loss due to percolation, with efficient use of water, and can reduce or prevent salinization.

Partial Leader Optimizer
Authors: Kusuma Purba Daru , Hasibuan Faisal Candrasyah
Published: August 2023

A new swarm intelligence-based metaheuristic optimizer, namely Partial Leader Optimizer (PLO), is presented. PLO contains several autonomous agents that represent the solution. The best solution represents collective intelligence, i.e., the leader. PLO has distinct mechanics in finding the acceptable solution during the given iteration. Every agent moves to a specified target in every iteration. Two options can be chosen to determine the target. First, the target is calculated by pushing the virtual best solution away from the corresponding agent. Second, the target is randomly chosen within the solution space. This target selection is conducted stochastically based on the threshold that is set manually before the iteration. Then, several candidates are generated between the target and the agent's current location. The distance between adjacent candidates is the same. The agent moves to the best candidate and updates the best solution. Simulation is implemented to observe and analyze the PLOâ€™s performance. The well-known 23 benchmark functions are used as the optimization problems. In this simulation, PLO is benchmarked with marine predator algorithm (MPA), particle swarm optimization (PSO), average subtraction-based optimizer (ASBO), slime mold algorithm (SMA), and pelican optimization algorithm (POA). The result shows that PLO is competitive compared to these algorithms, especially in solving fixed-dimension multimodal functions. PLO is better than PSO, MPA, SMA, ASBO, and POA in optimizing 22, 19, 18, 9, and 20 functions out of 23, respectively.

Published: August 2023

Peanut (Arachis hypogaea L.) is one of the leading commodities in Indonesia that are consistently growing with high demand. However, its productivity in the current state is relatively few, thus causing dependency on imported products. Developing new varieties is one of the many solutions to these problems. Lurik peanuts are superior local varieties to any other peanuts in terms of productivity and disease resistance. Seed with the purple pattern is this cultivar's special characteristic and main attraction. This study aimed to identify and verify the activity of transposon genes in the seed pattern of Lurik peanuts. This research method was carried out by gene detection and sequencing analysis using PCR-AhMITEs (Arachis hypogaea Miniature Inverted Transposable Elements). The study used the Garuda variety as a comparison due to the absence of seed patterns, and it is a superior variety widely cultivated in Indonesia. Four types of primers used in this study were AhMITE1, AhTE0357, AhTE0391, and AhTE1317. The results revealed that the four primers had a linear relationship that could distinguish Lurik peanuts and Garuda peanuts based on the presence of transposon genes. The sequencing results confirmed that the detected genes were transposons from peanuts, located on chromosome 5 (Arahy.5), chromosome 9 (Arahy.9), chromosome 14 (Arahy.14), and chromosome 19 (Arahy.19). Based on the results of the study, the pattern on Lurik peanuts is an expression of the transposon gene activity.

Electromagnetic damper has been given special attention by many researchers and thus is among the important research areas in vibration system. This paper examines electromagnetic damper effect through simulation and experimental study. A vibration test rig incorporating a simple electromagnetic damper is designed and tested to examine the impact of electromagnetic force.The vibration system test rig can be operated as free vibration as well as a forced vibration system. In the simulation phase, the MATLAB model of the electromagnetic damper system is developed, considering its dynamic behavior. This simulation allows for the evaluation of the damper's effectiveness in reducing vibration amplitudes and settling times. Subsequently, an experimental setup is constructed to validate the simulation results. One of the key findings of this research is the comparison of different materials used as the outer cylinder of the electromagnetic damper system. The results indicate that aluminum exhibits a superior damping coefficient value of 2.8 kgs-1 compared to Nylon, which has a damping coefficient of 1.9 kgs-1. This observation highlights the significant impact of the damper's material choice on the vibration system's amplitude and settling time. The implementation of aluminum as the outer cylinder results in reduced amplitudes and quicker settling times in the vibration system. The combination of simulation and experimental studies enhances the understanding of the electromagnetic force's influence and validates the findings. The comparison of different materials for the damper's outer cylinder underscores the importance of material selection in achieving optimal damping coefficients and improved vibration system performance.

Published: August 2023

This study examined the effect of borax pentahydrate on alkali-activated very high-calcium fly ash (VHCF)-based geopolymer concrete. The VHCF obtained from the Pangkalan Susu power plant, Langkat, North Sumatra Indonesia had 25% CaO and was classified as C-class fly ash according to the new ASTM C618-19. It was activated using an alkali solution produced using Na2SiO3 and NaOH at a ratio of 1.5. Moreover, borax pentahydrate was used due to its high-calcium content, and the setting time, compressive strength, split tensile strength, and flexural strength were investigated. It was discovered from the results that the geopolymer paste had a flash final setting time. The findings showed that the initial setting time was 5 minutes while the final was 25 minutes. The addition of 12% borax pentahydrate was observed to have prolonged the setting time from 25 minutes to 80 minutes. Furthermore, the compressive strength of the concrete after 28 days was 50 MPa using NaOH 8 M and 2% borax pentahydrate while the split tensile strength was 4.7 MPa and the flexural strength was 4.53 MPa. This implies the borax pentahydrate is capable of acting as a retarder to prolong the setting time but has the ability to reduce the compressive, flexural, and split tensile strengths.

Published: August 2023

The traditional approach to weight measurement, which measures each sheep individually, is time-consuming, and sometimes, human error triggers other issues, such as data validation, sheep classification, etc. Most farmers or breeders nowadays still manage their livestock traditionally, which is inefficient. We proposed that the Livestock Live Monitoring System is designed to collect measured data in real-time and display data in graphics; these models combine Bluetooth Low Energy as a wearable sensor to identify animals and Smart Weight Measurement to deliver weight and health data to the cloud system. This system aims to measure livestock and store the data in the server application so livestock monitoring can be done in real-time and remotely. The technology used in this system is ESP32, Load Cell, Bluetooth Low Energy, and Message Queue Telemetry Transport Protocol. Wearable devices act as an identification tag for livestock, and a smart weight scale is used to weigh the livestock and integrate it with the system. Two sheep are used as experiment objects, and their measured weight is compared to their weight when measured traditionally using a conventional scale. Based on the experiment, the weight data measured using the system has an accuracy of 99.82% for sheep number 1 and 99.17% for sheep number 2. This proposed system provides many benefits, including real-time livestock monitoring, cost efficiency, and an efficient feeding system for sheep using weight data.

COVIDâ€“19 is a new type of ailment caused by the strenuous acute respiratory syndrome, namely SARSâ€“CoV-2, also frequently wellâ€“known as the Coronavirus. An early tendency of COVIDâ€“19 for some sufferers can cause no symptoms at all as no experience is referred to as asymptomatic confirmation cases, yet these sufferers can still transmit COVIDâ€“19 to other people. Therefore, the authors developed a program using Machine Learning that sustains data to be analyzed based on the input served under the proposed methods of Convolutional Neural Networkâ€“Support Vector Machine (CNNSVM) and Convolutional Neural Networkâ€“Random Forest(CNNRF), along with several optimizers to be compared. Convolutional Neural Networks is a deep learning algorithm that can train large data sets with millions of parameters and has attracted attention in various fields that are commonly used for the classification and detection of Convolution in Neural Networks. In amalgamation with Support Vector Machines, a technique that uses two vectors to form a dividing line or side and fairly high accuracy,y random forests classification. In the manner of image data obtained from ChestXâ€“ray images of people with COVIDâ€“19 from the Italian Society of Medical and Interventional Radiology (SIRM), a total of 1750 observations consisting of 1000 data for COVIDÂ¬â€“19 images and 750 data for non-COVIDâ€“19 images. This research aims to determine which optimizer is better for analyzing COVIDâ€“19 ChestXâ€“ray images by evaluating both methods. Hopefully, both methods can provide higher accuracy for future studies with wider databases to provide better results for analyzing different ailments.
Multidimensional Poverty Across Agroecology in Occidental Mindoro, Philippines
Authors: Herpacio Charles Allen L. , Irham Irham
Published: August 2023

Poverty in the context of rural farming is site-specific. The differences in natural resource endowment and availability of social services across Agroecology shape farming households' well-being. In the Philippines, there is a scant supply of comparative studies on the multidimensional poverty situation across different farming systems. This study aimed to close this knowledge gap by assessing the multidimensional poverty and its determinants across upland, lowland, and coastal farming areas in Occidental Mindoro, Philippines. Using the Alkire-Foster methodology, data from 210 randomly selected farming households revealed that five of seven households are multidimensionally poor. The coastal area registered the highest Multidimensional Poverty Index at 0.41, where most households are deprived of education, decent housing, clean fuel source, paved access road, and farmland. Also, the analysis exposed the poverty dominance of indigenous farming households over non-indigenous migrant households. For all the Agroecology, the households' lack of education and incapacity to take on economic opportunities and secure productive assets limits them from investing in things that improve their living conditions. Estimates of binary logistic regression showed that non-indigenous farming households with female and educated householders, fewer dependents, larger agricultural holdings, access to formal credits, and non-farm business are significantly less likely to fall into poverty. The local government and concerned development organizations may consider investing in social protection programs that improve access to formal education, spur on-farm and non-farm livelihood opportunities, and enhance public infrastructure services to reduce multidimensional poverty in Occidental Mindoro.

El presente artículo hace parte de los resultados obtenidos en una investigación cualitativa que se desarrolla en el Doctorado Interinstitucional de Educación de la Universidad Distrital Francisco José de Caldas y que se lleva a cabo en dos comunidades culturalmente diferenciadas. Específicamente se hace referencia a aspectos abordados en observaciones, entrevistas y grupos focales que se hicieron en dos instituciones educativas publicas de Colombia, una urbana y otra rural, y en las comunidades a las que pertenecen dichas instituciones, con el ánimo de posteriormente identificar, reconocer y establecer conocimientos locales tradicionales en torno a la alimentación, buscar rescatarlos (si es el caso) y así poder configurar corpus de conocimientos (que incluyan los conocimientos locales tradicionales) que puedan ser enseñados en las clases de ciencias a estudiantes de primaria. Se evidencia que en una de las instituciones y su comunidad existe un mayor arraigo de los conocimientos locales tradicionales, aunque con el pasar del tiempo y las generaciones estos se han ido perdiendo.
ANÁLISIS CUALITATIVO DE TESIS RELACIONADAS CON LA EDUCACIÓN AMBIENTAL DE LA MAESTRÍA EN DOCENCIA PARA LA EDUCACIÓN MEDIA SUPERIOR DE LA UNAM (MADEMS

Published: August 2023

El presente artículo se deriva de la investigación del grupo latinoamericano EArte que se desarrolla como parte del Colectivo de Investigadores en Educación Ambiental Superior en América Latina y Caribe (EArte-ALyC) en donde la UNAM es entidad participante. Se centra en el análisis de 19 tesis relacionadas con la educación ambiental que se realizaron en el periodo de 1976 a 2019, en el Programa de la Maestría en Docencia para la Educación Media Superior de la Universidad Nacional Autónoma de México (MADEMS-UNAM). Para darle contexto a la investigación se exponen brevemente los principales problemas que enfrenta la Educación Media Superior en México y se describe dicho programa.

Dentro de los hallazgos de la investigación se encuentra que el plan de estudios de este programa carece de un espacio curricular destinado para la enseñanza de la Educación Ambiental, sin embargo, la mayoría de las tesis estudiadas abordan temáticas ambientales y la implementación de estrategias educativas para su enseñanza, por lo que se observa que los conceptos vinculados con este campo se derivan de uno de los contenidos de la maestría, es decir, el desarrollo sustentable.

Por lo tanto, se concluye que es necesario que en este programa se refuerce la formación profunda sobre la Educación Ambiental para un mayor impacto en las acciones educativas.

Com base numa pesquisa qualitativa de cunho etnográfico, procuramos por meio da entrevista narrativa e observação participante coletar informações sobre o saber local inerente ao processo de produção do óleo a partir da polpa da semente de mafurra na comunidade de Canda, na Província de Inhambane em Moçambique. Por outro lado, procuramos analisar as referidas informações a luz dos pressupostos êmicos, éticos e dialéticos da etnomodelagem proposta por Rosa e Orey (2012), das reflexões sobre os saberes locais e o ensino de química feitas por Francisco (2004), com o intuito de delinear possibilidades da sua apropriação para os saberes escolares tendo como base os conteúdos de química do ensino secundário geral em Moçambique. Da análise feita, constatamos que no processo de produção de óleo de mafurra evidenciam-se  conceitos químicos relacionados às propriedades químicas e físicas como a densidade, temperaturas de ebulição e fusão, as propriedades dos materiais cerâmicos utilizados para a fabricação e conservação das bebidas e dos alimentos, quanto à sua condutibilidade, temperaturas de ebulição, solubilidade, a sua constituição, as transformações envolvidas na produção do material, a distinção entre tipos de misturas e os respectivos os métodos de separação, entre outros, que podem ser abordados no ensino de química em Moçambique.

From Starved Rock to Cancer Alley: Simulated Violence and Representational Collapse in the American West
Authors: Wöll Steffen
Published: August 2023

The Louisiana Purchase created a complex landscape of cultures and ethnicities located at the peripheries of the Early Republic. Some feared that it would threaten (White) American identity while others imagined the frontier as a clean slate on which the nation could reform its core values. Throughout the nineteenth century, axiomatic regeneration through (violent) experiences dominated peripheral-yet-central discourses of the American space. Shedding new light on the role of representation in the placemaking of the West, this article interweaves a reading of James Hall’s “The Pioneer” with experiences recovered from travelogues and diaries, as well as their embodiments in material culture. I argue that violence was not only a hallmark of settler colonialism but also a crucial narrative device that bridged the gaps between reality and fiction as well as center and margin. These dynamics, the article suggests, regularly culminated in representational excesses of conspicuous and consumable spectacles of violence.

O objetico é avaliar o perfil clínico, epidemiológico e quais foram as condutas médicas em pacientes com nódulos mamários palpáveis no exame físico em uma clínica no Sul de Santa Catarina. Trata-se de um estudo observacional descritivo, de coleta de dados secundários, com abordagem quantitativa, avaliando prontuários de pacientes com nódulos palpáveis no exame físico em uma clínica no Sul de Santa Catarina. Os dados coletados foram: sociodemográficos como idade e escolaridade, além de fatores ginecológicos, como menarca e uso de anticoncepcionais. Tem-se como resultados que a idade média da população estudada foi de 40,13 anos. A prevalência de nódulos mamários palpáveis foi de 5,97%; 60,8% das mulheres negavam histórico de neoplasia familiar; 56,7% não possuíam sintomas mamários no momento da consulta e 52,5% tinham duas ou mais gestações. Em relação a conduta médica, 50,8% foi solicitado ultrassonografia e 35,8% tinham como localização principal do nódulo o quadrante superior externo esquerdo da mama. Conclui-se que o perfil clínico das pacientes foi de mulheres com média de idade de 40,13 anos, sem histórico de neoplasias, com ausência de sintomas mamários, sendo o ultrassom o método de imagem mais utilizado. A partir dos dados deste estudo é possível traçar estratégias para abordagem preventiva de mulheres com perfil semelhante.
O ACADÊMICO EM SEU ESTÁGIO NÃO OBRIGATÓRIO: AS NARRATIVAS DAS CRIANÇAS COM DEFICIÊNCIA SOBRE SUA ATUAÇÃO NA ESCOLA

Published: August 2023

Este estudo foi realizado com a intenção de conhecer as reflexões das crianças com deficiência sobre seus estagiários com um olhar sobre o estágio não obrigatório. Esta pesquisa é de característica qualitativa e com o modelo de entrevista semiestruturado. A pesquisa foi realizada com quatro alunos que possuem deficiência matriculados no quinto ano de escolas da rede de ensino público municipal de Criciúma - SC. A pesquisa conta com embasamento teórico de alguns autores como: Pimenta e Lima (2012), Demschinski (2020) e Siqueira; Cunha; Glat e Silva (2012). Assim, podemos observar através desta pesquisa que o estágio não obrigatório é tão importante para a formação do acadêmico quanto para a formação das crianças com deficiência. Entretanto, ainda possuem muitos percalços que tornam o estágio irregular e desvalorizam o trabalho realizado pelo acadêmico estagiário.

PALAVRAS CHAVE: Inclusão. Estágio não obrigatório. Crianças com deficiência.
A BASE NACIONAL COMUM CURRICULAR E O NOVO ENSINO MÉDIO: NATURALIZANDO DESIGUALDADES
Authors: Machado Damila , Mueller Rafael Rodrigo
Published: August 2023

O presente artigo busca investigar quais são os impactos provocados pela lei nº 13.415/2017, a qual alterou a lei de diretrizes e bases nº 9.394/96 e instituiu a reforma do novo ensino médio. Entende-se portanto como fundamental, decifrar quais são as implicações que a nova reforma pode produzir na etapa do ensino médio na escola pública, compreendendo esta etapa como uma das mais disputadas pelas políticas de viés neoliberal. A pesquisa possui cunho qualitativo e os procedimentos utilizados para a realização deste trabalho foram de caráter documental e bibliográfico. Dessa forma, a origem da investigação presente está circunscrita aos documentos oficiais, tendo como amparo a Base Nacional Comum Curricular de 2018, a Lei Nº 13.415/2017, o Plano Nacional de Educação (PNE), instaurado pela Lei Nº 13.005/2014 (que estabelece as metas que pretende cumprir com vencimento a cada dez anos, no campo da educacional), além das Diretrizes Curriculares Nacionais para o Ensino Médio (DCNEM). As políticas na esfera educacional que são direcionadas pelos organismos internacionais naturalizam as desigualdades no cenário educacional, e, portanto, torna-se importante construir uma proposta que seja diametralmente oposta, pensada numa formação humana que atenda a todos, e não apenas a uma parcela da sociedade.

The effect of adenoidectomy on pulmonary function in children: prospective controlled study
Authors: YAGIZ AGAYAROV Ozlem , ALİYEVA Aynur , KOCAHAN Sayad
Published: August 2023

Objectives: Adenotonsillar hypertrophy (AH) is a prevalent condition in children that can cause significant complications if left untreated. In this study, we investigated the impact of adenoidectomy on pulmonary function tests (PFTs) and explored the relationship between spirometric parameters in affected children. By evaluating these factors, we can better understand the post-surgical outcomes and the potential benefits of surgical intervention.
Methods: The present study utilized a prospective controlled design to conduct a before and after clinical trial involving 23 children diagnosed with upper airway obstruction resulting from AH. Five specific spirometric parameters were selected to evaluate pulmonary function before and 1-3 months following the adenoidectomy procedure. Additionally, adenoid grade scores and gender differences were recorded for each patient to assess their effect on the lung.
Results: Peak expiratory flow (PEF) (p = 0.002), the first second of expiration (FEV1) (p < 0.001), and the ratio of FEV1/FVC (p = 0.001) significantly increased postoperatively. However, no significant correlations were found between the forced vital capacity (FVC) (p = 0.39) and mid-expiratory forced expiratory flow (FEF25-75) (p = 0.2). Rising of the FVC, PEF, FEV1, and FEV1/FVC was observed in AH grade III patients compared to AH grade IV patients following the surgical intervention, in comparison to the preoperative baseline, especially statistical significance was FEV (p = 0.047), indicating a noteworthy change in lung function.
Conclusions: These findings emphasize the beneficial effects of adenoidectomy on PFTs and highlight that adenoidectomy positively affects the upper and lower airways.
