Published: July 2024

Purpose: The aim of the study was to assess cervical cancer screening practice and factors associated with cervical cancer screening among women in Kitale Municipality.
Methodology: A cross-sectional study using stratified simple sampling to select a sample of 422 women aged 30-69 years old was adopted. A Structured questionnaire was used to collect data. Data entry and coding was done in SPSS v20. Subsequent content analysis was used to descriptively summarize and compute proportions, mean and standard deviation in reporting    socio-demographic data. To test the association between dependent and independent variables, Chi-square was used while Multiple Logistic Regression analysis was used to generate adjusted odds ratios of association. Data was presented in form of tables and figures.
Findings: Findings suggest that 76% (321) knew about cervical cancer screening. Results revealed that only 27% (114) had ever gone for cervical cancer screening. There was a crude significant association between awareness of cervical cancer risk factors and screening (OR=1.08, p=0.000). Awareness therefore encouraged screening. Unawareness of cervical cancer risk factors & screening tests available, low socio-economic status and socio-demographic factors were associated with low screening practice.  In conclusion, this study found that there was modest awareness about cervical cancer but low screening practice among women in this Municipality.
Unique Contribution to Theory, Practice and Policy: The study recommends scale up for cervical cancer awareness and screening campaigns by stakeholders. The current study has added knowledge that will be used by stakeholders advocating for cervical cancer awareness and screening that will aid in uptake important in early detection and treatment of cervical cancer cases, and hence reducing case morbidity and mortality.

Salah satu transformasi dan inovasi yang diperkenalkan oleh Mendikbudristek Bapak Nadiem Makarim adalah penggunaan Aplikasi Platform Merdeka Mengajar (PMM), yang bertujuan untuk memberikan dukungan kepada guru dan kepala sekolah dalam pengelolaan pembelajaran serta peningkatan kinerja di lingkungan sekolah. Tujuan dari penelitian ini adalah untuk mengetahui dan menganalisis Implementasi pengelolaan kinerja guru dan kepala sekolah melalui Aplikasi PMM serta faktor penghambat Implementasi pengelolaan kinerja guru dan kepala sekolah melalui Aplikasi PMM di Kabupaten Serdang Bedagai. Penelitian ini menggunakan penelitian deskriptif kualitatif dengan jenis studi kasus. Teknik pengumpulan data yang digunakan dalam penelitian ini adalah wawancara dan menggunakan kuesioner sebagai instrument penelitian. Untuk menganalisis proses implementasi aplikasi PMM dalam pengelolaan kinerja guru dan kepala sekolah di Kabupaten Serdang Bedagai, peneliti menggunakan teori Charles O. Jones, yaitu: organisasi, interpretasi dan aplikasi. Dari hasil penelitian diperoleh data mengenai upaya sosialisasi program sudah berjalan dengan baik ditandai dengan pelaksanaan pendampingan secara serentak dan merata dengan koordinasi dari Dinas Pendidikan Provinsi, Cabang Dinas, Dinas Pendidikan Kabupaten dan BBGP serta melalui tim pendampingan pengisian RHK yang dibentuk oleh BBGP yang berasal dari guru penggerak. Aplikasi PMM memberikan kemudahan dalam penyusunan RHK dan lebih efisien karena lebih terintegrasi, selaras dengan kegiatan pembelajaran di sekolah dan peningkatan kompetensi pendidikan. Namun pemahaman guru terkait perencanaan RHK masih kurang karena program ini masih baru dan belum terbiasa dengan aplikasi PMM.  Kendala yang menjadi faktor penghambat yang dihadapi ada pada akses internet yang terbatas atau tidak stabil dan pemahaman guru yang masih kurang dalam pengelolaan kinerja melalui aplikasi PMM.

Published: July 2024

Introduction

The relationship between the intestinal microbiota, metabolites and inflammatory bowel disease (IBD) development is still being sought. We aimed to assess whether the gut microbiome and serum metabolic profile are consistent with a diagnosis of Crohn’s disease (CD) or ulcerative colitis (UC) in children with newly diagnosed disease.

Material and methods

Bacterial abundance in fecal samples was evaluated using a 16S rRNA DNA-based test in treatment-naive children with IBD (n=18) and healthy controls (n=10). Metabolic fingerprinting of serum samples of the same individuals was estimated using liquid chromatography coupled with mass spectrometry.

Results

It was not possible to discriminate between CD and UC patients based on the gut microbiota profiles, but surprisingly, on the Principal Component Analysis (PCA) model we observed a spontaneous separation of IBD patients into two groups, independently of IBD type. Then, serum metabolic profiles of these two microbiota-based groups of IBD patients were compared using orthogonal partial least squares discriminant analysis (OPLS-DA) modelling. Good quality models were obtained based on serum metabolomics data collected in positive and negative ion mode data. In total, 12 metabolites significantly discriminating these groups were identified.

Conclusions

Based on microbiota profiling a grouping of IBD patients, unrelated to the IBD type, was noted. These two groups also have specific serum metabolic profiles. Further studies are needed to assess whether IBD patients, depending on their gut microbiota and serum metabolite composition, require different treatments and if that impacts disease outcomes.

La población asturiana creció durante el siglo XVIII, sin embargo, algunas zonas de su territorio siguieron una tendencia muy diferente. Este es el caso de la Comarca Oscos-Eo, cuya población descendió en este periodo, experimentando un comportamiento demográfico que pareció ser compartido por distintas zonas del occidente asturiano en esta época. En este trabajo, a través de diversas fuentes (censos de población, libros parroquiales y padrones de moneda forera), se realiza un pormenorizado estudio sobre el comportamiento de la población de la comarca, intentando establecer las causas, y las fases de su descenso y estancamiento, a finales de la Edad Moderna.
Los centuriones auxiliares y sus funciones. Una aproximación por medio de la epigrafía del norte de África
Authors: Ortiz de Bruguera Jorge
Published: July 2024

Este trabajo pretende servir para mejorar el estado de los conocimientos sobre los centuriones auxiliares, mucho menos estudiados que sus homólogos de las legiones. La herramienta para lograrlo son aquellas inscripciones, procedentes del norte de África, que muestran a estos suboficiales asumiendo mandos extraordinarios o, simplemente, fuera de su campamento. Esta decisión se debe a que la información contenida en estos testimonios, sobre el verdadero alcance de las funciones y la autoridad de estos centuriones de los auxilia, resulta imprescindible para comprender qué grado de similitud se dio entre ellos y los centuriones de las legiones.

Published: July 2024

Using short stories has proven effective in second language learning and teaching. This study investigated the students’ perceptions of the use of short stories and their English proficiency. It was intended to identify the students’ benefits from using short stories and the challenges they encountered, as well as solutions to address them. The study targeted 1050 first-year students at the University of Rwanda, College of Business and Economics. The sample size was 222 students from the departments of Business and Information Technology (BIT) and Applied Statistics. This study was supported by the constructivism theory. The study adopted a descriptive approach, and data were collected through a questionnaire and focus group interviews. The questionnaire yielded quantitative data, whereas the focus group interviews generated qualitative data. Findings revealed that using short stories enabled students to develop the English language's four macro-skills, namely listening (94.6%), speaking (95.5%), reading (98.2%), and writing (95.9%). The findings also disclosed that short stories helped to increase students’ vocabulary (98.2%). However, the findings indicated that students had difficulties grasping conveyed messages because of limited vocabulary, spelling difficulties, and little knowledge of English tenses, and that they lacked confidence to present their stories in front of colleagues. They could overcome these challenges, though, by looking up the meanings of new words and scaffolding each other’s learning. The study concluded that short stories might be useful language materials and recommended them as adequate materials to mediate second language learning.
Upper-atmosphere responses to the 2022 Hunga Tonga–Hunga Ha′apai volcanic eruption via acoustic gravity waves and air–sea interaction

Published: July 2024

Abstract. A multi-group of strong atmospheric waves (wave packet nos. 1–5) over China associated with the 2022 Hunga Tonga–Hunga Ha′apai (HTHH) volcano eruptions were observed in the mesopause region using a ground-based airglow imager network. The horizontal phase speed of wave packet nos. 1 and 2 is approximately 309 and 236 m s−1, respectively, which is consistent with Lamb wave L0 mode and L1 mode from theoretical predictions. The amplitude of the Lamb wave L1 mode is larger than that of the L0 mode. The wave fronts of Lamb wave L0 and L1 below the lower thermosphere are vertical, while the wave fronts of L0 mode tilt forward above the lower atmosphere, exhibiting internal wave characteristics which show good agreement with the theoretical results. Two types of tsunamis were simulated; one type of tsunami is induced by the atmospheric-pressure wave (TIAPW), and the other type of tsunami is directly induced by the Tonga volcano eruption (TITVE). From backward ray-tracing analysis, the TIAPW and TITVE were likely the sources of wave packet nos. 3 and 4–5, respectively. The scale of tsunamis near the coast is very consistent with the atmospheric AGWs observed by the airglow network. The atmospheric gravity waves (AGWs) triggered by TITVE propagate nearly 3000 km inland with the support of a duct. The atmospheric-pressure wave can directly affect the upper atmosphere and can also be coupled with the upper atmosphere through the indirect way of generating a tsunami and, subsequently, tsunami-generating AGWs, which will provide a new understanding of the coupling between ocean and atmosphere.
Why did ozone concentrations remain high during Shanghai's static management? A statistical and radical-chemistry perspective
Authors: Zhu Jian , Wang Shanshan , Gu Chuanqi , Jiang Zhiwen , Zhang Sanbao , Xue Ruibin , Yan Yuhao , Zhou Bin
Published: July 2024

Abstract. During the period of April and May 2022, Shanghai implemented city-wide static management measures to control the spread of the Omicron variant. Compared to the lockdown in early 2020, the static management in 2022 occurred during the high-ozone season and lasted for a longer duration. It can be considered a “large-scale field experiment” to study the response of ambient ozone levels to emission reductions. During this period, we conducted comprehensive observations at Fudan University, Jiangwan Campus, in the northeast corner of Shanghai. Similar experiments were also conducted during the same period in 2020 and 2021. Despite the significant reduction of approximately 30 % in VOCs and around 50 % in NO2 due to static management in 2022, the average ozone level increased by nearly 23 % compared to 2020 and 2021. This suggests that the reduction in ozone precursors and other pollutants did not lead to a corresponding decrease in ozone concentrations as expected. Cluster analysis of diurnal patterns of ozone concentration revealed four distinct types of diurnal ozone variations. Cluster 3 and cluster 4, with high ozone levels, experienced significant increases in their shares during static management, ultimately leading to an overall increase in average ozone levels in 2022. According to the observation-based model (OBM) simulation analysis, the average peak concentrations of OH, HO2, and RO2 in 2022 were estimated to be 5.1×106, 4.7×108, and 2.6×108 molec.cm-3, respectively, representing an increase of about 30 % compared to the levels in 2020 and 2021. Although HONO photolysis was the main contributor to the primary source of ROx radicals, the radical-cycling process remained dominant for the overall production of ROx radicals. Due to a significant decrease in NO2 concentration relative to VOCs, the average VOC / NO2 ratio increased from 1.6 in 2020 to 3.0 in 2022, which is also reflected in the radical cycling. The ratio of OH radical propagation (OH + VOCs) to termination (OH + NO2) was 2.37, higher than 1.18 in 2020 and 1.78 in 2021, indicating that the different reduction proportions of precursors led to a higher VOC / NO2 ratio, strengthening the radical cycling. The differential reduction in precursor VOCs and NO2 levels due to static management is the underlying cause of the increase in ozone concentration in Shanghai.
Measurement report: Analysis of aerosol optical depth variation at Zhongshan Station in Antarctica

Published: July 2024

Abstract. Our understanding of aerosol optical depth (AOD) in Antarctica remains limited due to the scarcity of ground observation stations and limited daylight days. Utilizing data from the CE318-T photometer spanning from January 2020 to April 2023 at Zhongshan Station, we analysed the seasonal, monthly, and diurnal variations in AOD and Ångström exponent (AE). AOD median values increased from spring (0.033) to winter (0.115), while AE peaked during summer (1.010) and autumn (1.034), declining in winter (0.381), indicating a transition in dominant aerosol particle size from fine to coarse mode between summer and winter. Monthly mean AOD variation closely paralleled the proportion of AE<1, suggesting fluctuations in coarse mode particle proportions drive AOD variation. Increases in AOD during spring and winter correlated with decreases in fine mode fraction, while increases during summer and winter related to fine mode particle growth and aging. We observed a peak in AOD (~0.06) at 14:00 local time at Zhongshan Station, possibly associated with a slight decrease in boundary layer height (BLH). Additionally, higher (lower) wind speeds corresponded to lower (higher) AOD values, indicating the diffusion (accumulation) effect. The temperature and AOD showed an insignificant positive correlation between (R = 0.22, p = 0.40), relative humidity exhibited a significant negative correlation with AOD (R = -0.59, p = 0.02). Backward trajectory analysis revealed that coarse particles from the ocean predominantly contributed to high AOD daily mean values in summer, while fine particles on low AOD days originated mainly from the air mass over the Antarctic Plateau.
Impact of reservoir evaporation on future water availability in north-eastern Brazil: a multi-scenario assessment
Authors: Rodrigues Gláuber Pontes , Brosinsky Arlena , Rodrigues Ítalo Sampaio , Mamede George Leite , de Araújo José Carlos
Published: July 2024

Abstract. The potential effects of climatic changes on water resources are crucial to be assessed, particularly in dry regions such as north-east Brazil (1 million km2), where water supply is highly reliant on open-water reservoirs. This study analyses the impact of evaporation (by the Penman method) on water availability for four scenarios based on two regional climatic models (Eta-CanESM2 and Eta-MIROC5) using the Representative Concentration Pathways (RCPs) 4.5 and 8.5. We compared the water availability in the period of 2071–2100 with that of the historical period (1961–2005). The scenarios derived from the Eta-CanESM2 model indicate an increase in the dry-season evaporative rate (2 % and 6 %, respectively) by the end of the century. Unlike the above scenarios, the ones derived from the Eta-MIROC5 model both show a change in the dry-season evaporative rate of −2 %. Consequently, for a 90 % reliability level, the expected reservoir capacity to supply water with high reliability is reduced by 80 %. It is reasonable to state that both patterns of future evaporation in the reservoirs may prove to be plausible. Because model-based projections of climate impact on water resources can be quite divergent, it is necessary to develop adaptations that do not need quantitative projections of changes in hydrological variables but rather ranges of projected values. Our analysis shows how open-water reservoirs might be impacted by climate change in dry regions. These findings complement a body of knowledge on the estimation of water availability in a changing climate and provide new data on and insights into water management in reservoir-dependent drylands.
Semi-Analytical Methodology for Fretting Wear Evaluation of the Pitch Bearing Raceways Under Operative and Non-Operative Periods
Authors: Cubillas David , Olave Mireia , Llavori Iñigo , Ulacia Ibai , Larrañaga Jon , Zurutuza Aitor , Lopez Arkaitz
Published: July 2024

Abstract. Current methodologies for the evaluation of fretting in pitch bearing raceways only consider damage induced by oscillating control movements. However, pitch bearings can remain static for long operative and non-operative periods, and previous works have shown that load fluctuations cause fretting damage due the small movements and deformations at the contact. In this work a semi-analytical methodology is presented and an analysis of the fretting phenomenon in pitch bearing raceways under both productive and non-productive periods of static pitch control is accomplished. The analysis is performed following the energy-based wear model and the calculation of a total 30 times series of 10 minutes of duration concerning winds speeds from 3 m/s to 25 m/s. As result, critical locations, and critical times, defined as the maximum allowable time in the same position before the damage is developed, are presented for the different wind speeds. Additionally, a cumulative method is proposed for simplified calculations of variable winds.

Published: July 2024

O objetivo deste artigo é identificar o papel das mulheres no planejamento das celebrações religiosas e práticas tradicionais realizadas no assentamento Jatobá em Cáceres-MT. No caso estudado, a festa foi organizada para arrecadar fundos para a ampliação da igreja do Assentamento Jatobá. Homens e mulheres dos assentamentos vizinhos, como Corixo e Sapicuá, também participaram tanto do planejamento quanto do consumo durante o evento, auxiliando na arrecadação de fundos. O estudo qualitativo foi realizado por meio de entrevistas e pesquisa bibliográfica. Observou-se que, embora as mulheres estivessem presentes o tempo todo e a principal organizadora fosse uma mulher, os homens ainda mantinham um papel de protagonismo na festa religiosa. Contudo, ficou claro que, sem a dedicação e o esforço dessas mulheres, a festa não teria acontecido, reafirmando a importância de reconhecer e valorizar suas contribuições. O envolvimento das mulheres em diversas áreas da festa não apenas assegura o sucesso das celebrações, mas também fortalece os laços comunitários e promove um ambiente solidário e colaborativo.

Optimization of UAV formation positioning accuracy based on double circle crossing method
Authors: Xie Yuchen
Published: July 2024

This paper delves into the optimization of positioning accuracy for Unmanned Aerial Vehicles (UAVs) in a circular formation. The study commences by establishing a polar coordinate system leveraging the positions of two reference UAVs, FY00 and FY01, whose locations are presumed to be stable and error-free. Utilizing the triangulation method within this coordinate system, we determine the positions of the remaining UAVs based on the direction information received from signal transmissions. Under the premise that positional deviations are confined to a range of ±5°, we employ an exhaustive method to discern the correlation between interval numbers and direction information. This approach facilitates the precise positioning of UAVs, despite minor location discrepancies. Subsequently, an iterative adjustment scheme is introduced to refine the distribution of UAVs along a circular path. Through a series of iterative computations, the UAVs are adjusted to achieve an even distribution, with the positioning error maintained within an acceptable margin of approximately 3 meters. The methodology integrates mathematical modeling with computational simulations, demonstrating the efficacy of the double circle crossing method in enhancing the accuracy of UAV formation positioning. The paper concludes with the validation of the proposed models through Matlab simulations, confirming the potential for practical application in optimizing UAV formation positioning tasks.
