Published: November 2023

Working life is as essential and indispensable as private life for people. Paying equal attention to work and private life is the way to balance these living spaces. Work-private life balance is essential both for the uninterrupted functioning of organizations and for the employees to continue their private life healthily. This study aims to reveal school administrators’ views on work- private life balance. Of qualitative research methods, a phenomenological research design was used to examine the subject in-depth, obtain rich findings, and understand the phenomenon better. The study participants comprised 50 school administrators, 19 females and 31 males, selected using purposeful and snowball sampling methods from 275 public high school administrators working in four central districts of Mersin in the 2021-2022 academic year. All the data were collected through face-to-face interviews and divided into codes, categories, and subcategories using content analysis. At the end of the analysis, the findings relating to five themes were created considering the literature. Although the work- private life balance was taken into account when asking questions to study participants, it was discovered that school administrators working in public high schools experienced a work- private life imbalance.

Authors: Chiwala Beatrice , Jacobs Choolwe , Makasa Mpundu , Silumbwe Adam , Wamunyima Monde Mercy , Zulu Joseph  Mumba
Published: November 2023

Introduction Several interventions have been implemented to improve access for all to safely managed sanitation in sub-Saharan Africa (SSA) since the beginning of the Sustainable Development Goals in September 2015. However, consolidated evidence on how such interventions worked or not worked remains limited. The proposed systematic review aims to synthesis evidence on how, why and under which circumstances the implementation of such sanitation interventions in SSA succeeded or failed so as to draw lessons for any future similar interventions. Methodology A systematic review protocol was designed and registered in PROSPERO – registration number CRD42023468109. Literature searches will be conducted in multiple electronic databases (from 2015 to 2023), including PubMed, Embase, CINAHL, Scopus, African Journal Online and Google scholar. Gray literature from ProQuest and Theses Global (PQTD) will also be searched. Other databases to be searched will be from IRIS- (WHO Digital Publications), United Nation Children Emergency Fund (UNICEF) and World Bank. Keyword searches will be used to identify articles. Peer-reviewed full text articles written in English and documenting how, why and in which contexts sanitation interventions improve access to safely managed sanitation will be considered eligible for inclusion. Two reviewers will independently screen eligible titles, abstracts and full articles with the third reviewer to help resolve any disputes. Assessment risk of bias in included studies will be appraised using the appropriate Critical Appraisal Skills Programme (CASP) checklist for systematic review and disputes will be resolved through discussion and consensus. The narrative and thematic synthesis of findings will be conducted. Discussion Understanding how and why certain sanitation interventions contribute to safely managed sanitation in SSA could guide program implementers on how to design interventions that contribute to the attainment of Sustainable Development Goal number 6.2 of universal access for all to adequate and equitable sanitation. The review will further compliment the limited studies that focus only on sanitation in SSA.

The development of the world of technology that is happening more rapidly now makes access to the digital world more wide open and easier. However, not everyone can easily and understand how to use this access, especially related to the use of digital finance in the world of Micro, Small and Medium Enterprises (MSMEs) due to low public education. Lack of information and knowledge on how to use and utilize digital finance makes some entrepreneurs use it. MSME business owners must continue to play a role in supervising, bookkeeping and recording stock entry and exit, recording sales and payments is still done manually by most MSMEs in Balikpapan City. With the increasingly rapid developments in the digital world, MSME business actors are expected to be able to innovate all MSME activities in a Management Information System (MIS) as the aim of business development with technological transformation and speed of service in handling customers and business management. This study aims to examine the effect of digital financial literacy on the performance of MSMEs with a research approach using the questionnaire method for MSMEs in Balikpapan City. Multiple regression analysis was applied to test the effect of digital financial literacy on MSME performance by controlling for manager profiles and the special characteristics of MSME. The research results prove that Digital financial literacy has a positive and significant effect on the performance of MSMEs. Managers/owners with digital financial literacy skills understand financial concepts related to business, debt, savings, insurance, and investment in the digital era which ensures good performance of their business.

Introduction

In Hungary, the HUN-VE 3 study determined the comparative effectiveness of various primary and booster vaccination strategies during the Delta COVID-19 wave. That study included more than 8 million 18-100-year-old individuals from the beginning of the pandemic. Immunocompromised (IC) individuals have increased risk for COVID-19 and disease course might be more severe in them. In this study, we wished to estimate the risk of SARS-CoV-2 infection and COVID-19 related death in IC individuals compared to healthy ones and the effectiveness of the BNT162b2 vaccine by reassessing HUN-VE 3 data.

Patients and methods

Among the 8,087,988 individuals undergoing follow-up from the onset of the pandemic in the HUN-VE 3 cohort, we selected all the 263,116 patients with a diagnosis corresponding with IC and 6,128,518 controls from the second wave, before vaccinations started. The IC state was defined as two occurrences of corresponding ICD-10 codes in outpatient or inpatient claims data since 1 January, 2013. The control group included patients without chronic diseases. The data about vaccination, SARS-CoV-2 infection and COVID-19 related death were obtained from the National Public Health Center (NPHC) during the Delta wave. Cases of SARS-CoV-2 infection were reported on a daily basis using a centralized system via the National Public Health Center (NPHC).

Results

Out of the 263,116 IC patients 12,055 patients (4.58%) and out of the 6,128,518 healthy controls 202,163 (3.30%) acquired SARS-CoV-2 infection. Altogether 436 IC patients and 2141 healthy controls died in relation to COVID-19. The crude incidence rate ratio (IRR) of SARS-CoV-2 infection was 1.40 (95%CI: 1.37-1.42) comparing IC patients to healthy controls. The crude mortality rate ratio was 4.75 (95%CI: 4.28-5.27). With respect to SARS-CoV-2 infection, interestingly, the BNT162b2 vaccine was more effective in IC patients compared to controls. Primary vaccine effectiveness (VE) was higher in IC patients compared to controls and the booster restored VE after waning. VE regarding COVID-19 related death was less in IC patients compared to healthy individuals. Booster vaccination increased VE against COVID-19-related death in both IC patients and healthy controls.

Conclusion

There is increased risk of SARS-CoV-2 infection and COVID-19 related mortality in IC patient. Moreover, booster vaccination using BNT162b2 might restore impaired VE in these individuals.
Dietary patterns in relation with nutritional outcomes and associated factors among adolescents: implications for context-specific dietary intervention for the Agrarian Community, Northwest Ethiopia
Authors: Agedew Eskezyiaw , Abebe Zeweter , Ayelign Abebe
Published: November 2023

Introduction

Dietary pattern analysis allows us to characterize the dietary intakes of individuals rather than nutrient intake data and strongly predicts disease risks. The relationship between food intake and adolescents’ nutritional health is not well understood yet. Therefore, this study aimed to generate evidence for context-specific dietary intervention for adolescents.

Objective

This study aimed to determine dietary patterns and their relationship with nutritional outcomes and identify the contributing factors among adolescents in the Agrarian Community of Northwest Ethiopia.

Methods

A cross-sectional survey was conducted among 622 randomly selected adolescents. Dietary data were collected over a 1-week recall period using the Food Frequency Questionnaire (FFQ). After testing the basic assumptions, an exploratory factor analysis was conducted to determine the dietary patterns. Anthropometric data on weight and height were collected to determine the nutritional status using WHO Anthroplus 2010 software. A chi-square test was conducted to evaluate the effect of different dietary patterns on nutritional outcomes. A multivariable binary logistic regression model was used to identify factors affecting the dietary patterns of adolescents.

Result

Three types of dietary patterns, namely, traditional, mixed, and animal-source foods with traditional alcoholic beverage consumption were identified. These dietary patterns explain 58.64% of the variance in adolescent diet in the study setting. The burden of stunting was 15.12% vs. 11.21, 19.40% vs. 6.94, and 8.36% vs.17.97% among adolescents with lower traditional, mixed, and higher animal sources with alcoholic dietary pattern consumption habits, respectively (value of p <0.05). Adolescents who resided in low-land agroecology (AOR = 2.44; 95% CL: 1.24, 4.81) and had access to animal-source foods (AOR = 1.64; 95% CI: 1.04, 2.60) were associated with lower consumption of traditional dietary patterns. Similarly, adolescents who resided in low-land (AOR = 1.80; 95% CI: 1.18, 2.74) had formal education (AOR = 2.38; 95% CI: 1.35, 4.19) and had poor nutrition knowledge (AOR = 2.83; 95% CL: 1.55, 5.19) were associated with lower consumption of mixed dietary patterns. Moreover, adolescents residing in the high-land (AOR = 2.50; 95% CI: 1.37, 4.56) and being female (AOR =1.87; 95% CI: 1.27, 2.74) were significant factors associated with lower consumption of animal-sourced foods with traditional alcoholic beverage consumption patterns.

Conclusion

Multidimensional modifiable factors were explored that could be targeted for public health interventions for the identified dietary patterns. Integrated and multifaceted dietary intervention approaches are needed to promote healthy diets and discourage the consumption of unhealthy diets to reduce undernutrition in the study area and similar settings.
Guidelines for assessment of affect-related constructs
Authors: Williams David M. , Rhodes Ryan E.
Published: November 2023

Research on affect-related constructs as determinants of health behavior is increasing. The Affect and Health Behavior Framework (AHBF) provides a schematic structure to label, organize, and integrate affect-related constructs. To further facilitate research and theory development in health behavior science, the purpose of the present paper is to provide a critical review and guidelines for assessment of the affect-related constructs in the AHBF. The paper is organized based on the categories of constructs in the AHBF: Affective response to health behavior, incidental affect, affect processing, and affectively charged motivation. Future research should work toward parsing constructs where possible as well as identifying overlap. Researchers are advised to consider conceptual underpinnings and methodological nuances when assessing affect-related constructs in order to build a cumulative science of affective determinants of health behavior.

Published: November 2023

Mycoplasma gallisepticum (MG) is recognized as a principal causative agent of avian chronic respiratory disease, inflicting substantial economic losses upon the poultry industry. However, the extensive use of conventional antibiotics has resulted in the emergence of drug resistance and various challenges in their clinical application. Consequently, there is an urgent need to identify effective therapeutic agents for the prevention and treatment of mycoplasma-induced respiratory disease in avian species. AMP-activated protein kinase (AMPK) holds significant importance as a regulator of cellular energy metabolism and possesses the capacity to exert an anti-inflammatory effect by virtue of its downstream protein, SIRT1. This pathway has shown promise in counteracting the inflammatory responses triggered by pathogenic infections, thus providing a novel target for studying infectious inflammation. Quercetin possesses anti-inflammatory activity and has garnered attention as a potential alternative to antibiotics. However, there exists a gap in knowledge concerning the impact of this activation on MG-induced inflammatory damage. To address this knowledge gap, we employed AlphaFold2 prediction, molecular docking, and kinetic simulation methods to perform a systematic analysis. As expected, we found that both quercetin and the AMPK activator AICAR activate the chicken AMPKγ1 subunit in a similar manner, which was further validated at the cellular level. Our project aims to unravel the underlying mechanisms of quercetin’s action as an agonist of AMPK against the inflammatory damage induced by MG infection. Accordingly, we evaluated the effects of quercetin on the prevention and treatment of air sac injury, lung morphology, immunohistochemistry, AMPK/SIRT1/NF-κB pathway activity, and inflammatory factors in MG-infected chickens. The results confirmed that quercetin effectively inhibits the secretion of pro-inflammatory cytokines such as IL-1β, TNF-α, and IL-6, leading to improved respiratory inflammation injury. Furthermore, quercetin was shown to enhance the levels of phosphorylated AMPK and SIRT1 while reducing the levels of phosphorylated P65 and pro-inflammatory factors. In conclusion, our study identifies the AMPK cascade signaling pathway as a novel cellular mediator responsible for quercetin’s ability to counter MG-induced inflammatory damage. This finding highlights the potential significance of this pathway as an important target for anti-inflammatory drug research in the context of avian respiratory diseases.

The objective of the present study was to develop PTF-loaded solid lipid nanoparticles (PTF-SLNs) and investigate their efficacy in treating lung cancer. The PTF-SLNs were prepared by the thin film hydration method and verified by FTIR and TEM. Their physicochemical properties were characterized by particle size, polydispersity index (PDI), zeta potential, entrapment efficiency (EE), drug loading (DL), etc. Then, the pharmacodynamic studies of PTF-SLNs were performed on Lewis lung cancer cells and tumor-bearing mice. Finally, the safety studies were assessed by organ index, serum biochemical indicators, and histopathological changes. The PTF-SLNs were characterized by around 50 nm sphere nanoparticles, sustained ideal stability, and controlled drug release effects. The pharmacodynamic evaluation results showed that PTF-SLNs had stronger anti-tumor efficacy than PTF. An in vitro study revealed a more obvious cytotoxicity and apoptosis effect. The IC 50 values of PTF and PTF-SLNs were 67.43 μg/mL and 20.74 μg/mL, respectively. An in vivo study showed that the tumor inhibition rates of 2 g/kg PTF and 0.4 g/kg PTF-SLNs were 59.97% and 64.55%, respectively. The safety preliminary study indicated that PTF-SLNs improve the damage of PTF to normal organs to a certain extent. This study provides a nanoparticle delivery system with phenolic herbal extract to improve anti-tumor efficacy in lung cancer.
Improved Gorilla Troops Optimizer-Based Fuzzy PD-(1+PI) Controller for Frequency Regulation of Smart Grid under Symmetry and Cyber Attacks
Authors: Pachaiyappan Rajivgandhi , Arasan Elankurisil , Chandrasekaran Kannan
Published: November 2023

In a smart grid (SG) system with load uncertainties and the integration of variable solar and wind energies, an effective frequency control strategy is necessary for generation and load balancing. Cyberattacks are emerging threats, and SG systems are typical cyber-attack targets. This work suggests an improved gorilla troops optimizer (iGTO)-based fuzzy PD-(1+PI) (FPD-(1+PI)) structure for the frequency control of an SG system. The SG contains a diesel engine generator (DEG), renewable sources like wind turbine generators(WTGs), solar photovoltaic (PV), and storage elements such as flywheel energy storage systems (FESSs) and battery energy storage systems (BESSs) in conjunction with electric vehicles (EVs). Initially, the dominance of the projected iGTO over the gorilla troops optimizer (GTO) and some recently suggested optimization algorithms are demonstrated by considering benchmark test functions. In the next step, a traditional PID controller is used, and the efficacy of the GTO method is compared with that of the GTO, particle swarm optimization (PSO), and genetic algorithm (GA) methods. In the next stage, the superiority of the proposed FPD-(1+PI) structure over fuzzy PID (FPID) and PID structures is demonstrated under various symmetry operating conditions as well as under different cyberattacks, leading to a denial of service (DoS) and delay in signal transmission.

Temporary clipping (TC) of the parent artery is a standard procedure in cerebral aneurysm surgery. According to a number of studies, TC lasting up to 5 minutes is safe in terms of the development of ischemic complications. In cases where a longer TC is required, it is recommended to alternate vessel shutdown with periods of reperfusion, which allows the procedure to be repeated many times without the risk of ischemia. The article presents a review of current scientific publications on TC in cerebral aneurysm surgery, showing that this is a very unpredictable procedure in terms of the development of complications, even when performed within the recommended time parameters. There are cases of ischemia with TC lasting less than 5 minutes and the opposite situation, when TC lasting more than 10–20 minutes does not lead to the development of complications. The review also presents current ideas on how to improve the safety of TC, including the use of intraoperative neurophysiological monitoring.

Authors: Leal Tyfane Sara Silva , Lima Verde Giselle Maria Ferreira
Published: November 2023

Introdução: O procedimento de clareamento dentário é altamente requisitado em consultórios odontológicos. No entanto, estudos sobre o assunto indicam que podem ocorrer efeitos colaterais durante ou após o tratamento, como a sensibilidade dentária. Tendo isso em vista, este estudo se propõe a explorar o impacto do clareamento dental na sensibilidade dentinária, um tema de grande relevância na odontologia estética. O procedimento de clareamento dental apresenta tanto vantagens quanto desvantagens, e uma das preocupações mais comuns é a sensibilidade que pode ser causada. Objetivo: Essa pesquisa tem como objetivo analisar e compreender os efeitos do clareamento dental na sensibilidade dentinária. Para entender melhor este fenômeno, foi realizada uma revisão de literatura abrangente, consultando bases de dados como PubMed, SCIELO, BVS. Os descritores utilizados para a busca foram clareamento, sensibilidade dentinária e adversidades causadas pelo clareamento. Os critérios de inclusão para os estudos foram: artigos em língua portuguesa e inglesa, publicados entre os anos de 2018 e 2023. Foram selecionados 10 estudos que abordavam os descritores supracitados. Foram excluídos aqueles que não abordavam esses temas, artigos incompletos e resumos. Os estudos selecionados foram organizados em sequência cronológica (de 2018 a 2023) para uma análise descritiva. Resultados: Foram achados ao todo 111 artigos, excluídos 21 duplicados e selecionados 90 para o levantamento. Conclusão: Se conclui que a melhor maneira de evitar a sensibilidade dentária é através de uma anamnese criteriosa e um exame clínico minucioso, levando em consideração a limitação individual de cada paciente. Além disso, recomenda-se utilizar agentes clareadores com menor concentração de peróxido e reduzir o tempo de contato com o esmalte.
COMPOSIÇÃO CORPORAL, AGILIDADE E POTÊNCIA DE MMII DE CRIANÇAS: UMA MOSTRA DA NOSSA INCOMPETÊNCIA EM CUIDAR DE DELAS
Authors: Vilela Junior Guanis de Barros , Passos Ricardo Pablo
Published: November 2023

Introdução: Crianças vivenciam um acelerado processo maturacional e de desenvolvimento das capacidades e habilidades físicas que serão cruciais para o resto de suas vidas. As crianças de hoje, com sobrepeso ou obesas, são vítimas de pais, professores, gestores públicos, pois é deles a responsabilidade de ofertar a elas melhores condições para uma vida saudável. Objetivos: 1) refletir sobre a falta de competência do adultos em cuidar das crianças; 2) avaliar a composição corporal, agilidade e potência de membros inferiores (MMII) de crianças de 6 a 9 anos. Métodos: amostra composta por 184 crianças de ambos os sexos, alunos de duas escolas públicas situadas na região central da cidade de Campinas. Foi utilizado o protocolo de dobras cutâneas tricipital e escapular utilizadas no protocolo de Lohman que utiliza idade e estatura das crianças. Foi utilizado o teste Shuttle Run para avaliar a agilidade e o teste de salto em altura para avaliar a potência de MMII, em ambos, as crianças, fizeram familiarização recreativa uma semana antes da coleta de dados. A pesquisa foi aprovada pelo Comitê de Ética em Pesquisa da instituição e os pais ou responsáveis pelas crianças leram e assinaram o Termo de Consentimento Livre e Esclarecido TCLE. Foi realizado teste de normalidade dos dados para eventual uso de testes paramétricos, sendo que em todos eles foi adotada p<0,50. Resultados: entre as crianças de 6 e 8 anos, ambos os sexos, não foram encontradas diferenças significantes para o percentual de gordura corporal (%G), relação cintura quadril (RCQ), índice de massa corporal (IMC), teste de agilidade e teste de potência de MMII. No grupo de 7 anos de idade foi encontrada diferença significante entre meninas e meninos, apenas no teste de saltar e alcançar (sig.= 0,019) e intervalo de confiança IC (-0,22; -0,02). No grupo de 9 anos foram encontradas diferenças significantes para %G com p=0,025 e IC de (-4,3; -0,30); para o teste Shuttle Run com p=0,000 e IC (0,21; 0,41) e para o teste de saltar e alcançar com p=0,02 e IC de (-0,25; -0,06). Isso permite concluir que essas crianças se encontram dentro dos limites antropométricos considerados adequados para as faixas etárias analisadas. Outro aspecto relevante é a fragilidade e/ou interesses escusos dos adultos que sistematicamente maltratam nossas crianças, ofertando a elas comida de qualidade ruim e privando-as de realizar mais atividade física.

This unique work assesses the diplomatic, commercial and political consequences of the conflicting interests of the British imperial government and colonial Trinidad on Venezuela. Imperial interests predominated and the British turned a blind eye to the use of Trinidad by opponents of Venezuelan regimes as a base for the overthrow of Venezuelan governments. The island colony played an important role in the politics of destabilization in Venezuela. The scholarship is based on a variety of primary sources, particularly the British Foreign Office and the Colonial Office as well as Venezuelan and US archives.

Published: November 2023

Using deep near-infrared Keck/MOSFIRE observations, we analyze the rest-optical spectra of eight star-forming galaxies in the COSMOS and GOODS-N fields. We reach integration times of ∼10 hr in the deepest bands, pushing the limits on current ground-based observational capabilities. The targets fall into two redshift bins, of five galaxies at z ∼ 1.7 and three galaxies at z ∼ 2.5, and were selected as likely to yield significant auroral-line detections. Even with long integration times, detection of the auroral lines remains challenging. We stack the spectra together into subsets based on redshift, improving the signal-to-noise ratio on the [O iii]λ4364 auroral emission line and, in turn, enabling a direct measurement of the oxygen abundance for each stack. We compare these measurements to commonly employed strong-line ratios alongside measurements from the literature. We find that the stacks fall within the distribution of z > 1 literature measurements, but a larger sample size is needed to robustly constrain the relationships between strong-line ratios and oxygen abundance at high redshift. We additionally report detections of [O i]λ6302 for nine individual galaxies and composite spectra of 21 targets in the MOSFIRE pointings. We plot their line ratios on the [O iii]λ5008/Hβ versus [O i]λ6302/Hα diagnostic diagram, comparing our targets to local galaxies and H ii regions. We find that the [O i]/Hα ratios in our sample of galaxies are consistent with being produced in gas ionized by α-enhanced massive stars, as has been previously inferred for rapidly forming galaxies at early cosmic times.

We present deep upper limits from the 2014 Murchison Widefield Array Phase I observing season, with a particular emphasis on identifying the spectral fingerprints of extremely faint radio frequency interference (RFI) contamination in the 21 cm power spectra (PS). After meticulous RFI excision involving a combination of the SSINS RFI flagger and a series of PS-based jackknife tests, our lowest upper limit on the Epoch of Reionization (EoR) 21 cm PS signal is Δ2 ≤ 1.61 × 104 mK2 at k = 0.258h Mpc−1 at a redshift of 7.1 using 14.7 hr of data. By leveraging our understanding of how even fainter RFI is likely to contaminate the EoR PS, we are able to identify ultrafaint RFI signals in the cylindrical PS. Surprisingly this signature is most obvious in PS formed with less than 1 hr of data, but is potentially subdominant to other systematics in multiple-hour integrations. Since the total RFI budget in a PS detection is quite strict, this nontrivial integration behavior suggests a need to more realistically model coherently integrated ultrafaint RFI in PS measurements so that its potential contribution to a future detection can be diagnosed.

O artigo tem como objetivo investigar o processo de constituição do imaginário da docência em Geografia a fim de analisar as fontes da permanência de um ensino tradicional e empirista deste componente curricular no espaço escolar. Para tanto, fundamenta-se nos conceitos de memória e identidade com o fito de problematizar as representações que os professores possuem acerca da profissão, da Geografia e do processo educativo. Representações estas que se originam desde as suas vivências na condição de aluno na escola e que influenciam o seu fazer pedagógico. O caminho metodológico envolve uma revisão bibliográfica centrada nos seguintes eixos basilares: memória, identidade, imaginário e ensino de Geografia. Adotou-se a abordagem (auto)biográfica em Educação como lente analítica para o estudo do imaginário da docência em Geografia, visto que concebe o percurso de vida como um percurso formativo que atua sobre a identidade pessoal e profissional. Portanto, evidencia-se que as memórias, sobretudo do itinerário de formação escolar, produzem um imaginário sobre o ser professor de Geografia que é pouco abalado ao longo da formação inicial docente e alimenta o processo identitário e os saberes e fazeres destes sujeitos na vida e na profissão, o que contribui para a naturalização de práticas empiristas nas posturas docentes.

Memory and teacher identity: a way to understand the teaching Geography
Abstract
This article aims to investigate the process of formation of the imaginary of geography teaching in order to analyze the sources of persistence of traditional and empiricist teaching of this subject at school. To this end, it is based on concepts of memory and identity with the purpose of problematizing representations that teachers have about the profession, geography, and the educational process. These representations originate from their own experiences as students in school and impact on their pedagogical practice. The methodological approach consists of a literature review focused on the following fundamental axes: memory, identity, imaginary and geography teaching. The (auto)biographical approach in Education was adopted as an analytical lens for studying the imaginary of geography teaching, since it conceives one’s life path as an educational pathway that acts on their professional and personal identity. Therefore, it is shown that memories, especially from the school education, create an imaginary of being a geography teacher, which is relatively unaffected throughout the initial teaching training and fuels these individuals’ identity process and their knowledge and practices in life and profession, contributing to the naturalization of empiricist practices in teachers’ attitudes.

Abstract. Efforts to monitor the emissions and absorptions of atmospheric carbon dioxide (CO2) over the globe and to understand their varying regional patterns with greater accuracy have intensified in recent years. This study evaluates the performance of a new model coupling, ICO, built around the Laboratoire de Météorologie Dynamique atmospheric general circulation model (LMDZ) for simulating CO2 transport. ICO utilizes the new icosahedral hydrostatic dynamical core called Dynamico running on an unstructured grid, which enables potential improvements in spatial resolution at the Equator while removing artificial distortions and numerical filters at the poles. Comparisons with a reference configuration using a structured latitude-longitude grid reveal that ICO well captures seasonal variations in CO2 concentrations at surface stations. While not significantly enhancing the capture of complex seasonal patterns, ICO maintains comparable accuracy. Both configurations exhibit similar vertical CO2 concentration profiles and display a consistent bias in the lower stratosphere relative to observational data. ICO demonstrates advantages in computational efficiency and storage, thanks to its reduced cell count per level and a homogeneous grid structure. It holds promise for future developments, including with the LMDZ offline model and associated inversion system, which contribute to the Copernicus Atmosphere Monitoring Service. Overall, the ICO configuration showcases the efficacy of utilizing an unstructured grid for the physics, and the capability of Dynamico in accurately simulating CO2 transport. This study emphasizes the importance of advanced modeling approaches and high-resolution innovative grids in enhancing our understanding of the global carbon cycle and refining climate models.
Altitudinal Control of Isotopic Composition and Application in Understanding Hydrologic Processes in the mid Merced River Catchment, Sierra Nevada, California, USA

Abstract. Mountain snowpack has been declining and more precipitation has fallen as rainfall than snowfall, particularly in the US West. Isotopic composition in stream water, springs, groundwater, and precipitation was examined to understand the impact of declining snowpack on hydrologic processes in the mid Merced River catchment (1,873 km2), Sierra Nevada, California, USA. Mean isotopic values in small tributaries (catchment area < 122 km2), rock glacier outflows and groundwater from 2005–2008 were strongly correlated with mean catchment elevation (R2 = 0.96 for δ2H, n = 16, p < 0.001), with an average isotopic lapse rate of -1.9 ‰/100 m for δ2H and -0.22 ‰/100 m for δ18O in meteoric water. The lapse rate did not change much over seasons and was not strongly affected by isotopic fractionation. A catchment-characteristic isotopic value was thus established for each sub-catchment based on the relation between isotopic composition and the mean catchment elevation to elucidate hydrometeorologic and hydrologic processes. Compared to Tenaya Creek without water falls, flow and flow duration of Yosemite Creek are much more sensitive to temperature increase due to a strong evaporation effect caused by waterfalls, suggesting possible prolonged dry-up period of Yosemite Falls in the future. Groundwater in the Yosemite Valley (~900–1,200 m) was recharged primarily from the upper snow-rain transition zone (2,000–2,500 m), suggesting its strong vulnerability to shift in snow-rain ratio. The information gained from this study helps advance our understanding of hydrologic responses to climate change in snowmelt-fed river systems.
ANALYZING THE CONNECTION BETWEEN GYMNAST'S STATURE AND MEDAL PERFORMANCE ON APPARATUSES IN MEN'S ARTISTIC GYMNASTICS
Authors: Bagci Emre
Published: November 2023

In order to achieve success in sports, certain physical fitness characteristics are necessary. This study aims to determine whether a relationship exists between the height of male gymnasts who have won medals in the World Championships and Olympic Games in Artistic Gymnastics, and the apparatus on which they achieved those medals. Competitions in Men’s Artistic Gymnastics at World Championships and Olympic Games are held in six apparatuses for individuals: floor exercise, pommel horse, rings, vault, parallel bars and horizontal bar. Each apparatus follows specific rules for evaluating gymnastics routines. Airborne acrobatics dominate on floor and vault, while support holds prominence on pommel horse and parallel bars, and hanging manoeuvres characterize rings and the high bar.  While a gymnast’s body height influences all forms of gymnastics, the question remains: who can rise to the top on each apparatus?
Within the scope of the research, the results between the years from 2009 to 2021 were examined. In this context, data from three Olympic Games (2012, 2016 and 2020) and nine World Championships (2009, 2010, 2011, 2013, 2014, 2015, 2017, 2018 and 2019) were used. The heights (251 sets of data) of the gymnasts who won medals in these competitions were evaluated.
While the shortest of the medal-winning gymnasts was 150cm tall (floor exercise and pommel horse) and the tallest 183cm (floor exercise and horizontal bar), the average height of the medal-winning gymnasts was 164.67cm (± 6.12). There is statistically significant difference between the heights of the gymnasts who won medals on apparatuses (p<0.05).

The purpose of the study was twofold: (a) to examine the impact of various finger placements and utilization on the quality, control, and overall efficiency of handstand performance, and (b) to investigate potential gender differences in relation to these factors. Thirty-one young competitive gymnasts (15 males; age: 12.60 ± 2.08, and 16 females; age: 13.31 ± 2.21) participated in this study. A portable posturographic digital platform was used to record hand area (cm²), maximal pressure (kPa), CoP (center of hand pressure) sway area (mm²), CoP linear distance displacement (mm) and CoP velocity. Derived data were analyzed in an integrated software module (Foot Checker, version 4.0). The intra-class correlation coefficient and the coefficient of variation supported the reliability of the measurements. One-way MANOVA showed better balance control for all gymnasts for the handstand with flat palms and joined and fully stretched fingers, followed by that of flat palms and wide open and fully stretched fingers, and wide flat palms and open and flexed fingers. Results from one-way MANOVA indicated no differences between males and females in age, training age, body mass, height, and body mass index. With control for the effects of age, training age, personal characteristics and hand area of support in place, females had better balance control compared to males based on differences in CoP sway area, CoP linear distance displacement, and CoP velocity. Despite the study's limitations, the findings contribute to the existing literature on balance control techniques in handstands in relation to gender differences. The study provides recommendations for more effective training for coaches and suggests avenues for future research.

Ülkemizde, teknolojik gelişmelere bağlı olarak 1950’lerin sonlarından günümüze kadar farklı ölçeklerde birçok topografik harita üretilmiş ve hizmete sunulmuştur. Bu çalışmada, 1992-1993 yıllarında analog imkanlar çerçevesinde üretilmiş 1:25.000 ölçekli topografik haritalardan elde edilen yükseklik değerleri ile haritacılık sektöründeki teknolojik gelişmelere paralel olarak yakın geçmişte (2009-2010) dijital imkanlarla üretilen topografik haritalardan elde edilen yükseklik değerleri üç farklı arazi örtüsü tipi (ziraat, parçalı orman ve orman) üzerinden CORS-GPS kullanılarak elde edilmiş yersel referans verilerine (ziraat formundaki çalışma sahasında 615 adet, parçalı orman formundaki sahada 3688 adet ve orman sahasında 1739 adet) dayalı olarak karşılaştırılmıştır. Karşılaştırmalarda, raster verilerin doğrudan kullanıldığı iki yöntem (Kesilmiş pafta (KP) ve Tam pafta (TP) yöntemleri) ve yeniden örnekleme ile elde edilen raster verilerin kullanıldığı iki yöntem (10 m mekansal çözünürlükle yeniden örnekleme (R10) ve 30 m mekansal çözünürlükle yeniden örnekleme (R30) yöntemleri) olmak üzere dört farklı raster yüzey modelinden elde edilen yükseklik değerlerinden yararlanılmıştır. Çalışma sonuçları, dijitalleşmenin topografik haritaların yükseklik hassasiyetleri üzerinde olumlu katkılar sağladığını göstermiştir. Analog ve dijital teknikle üretilen haritalar arasındaki yükseklik hassasiyetlerindeki farklılık ziraat arazi örtüsü tipinde oldukça belirgin iken, parçalı orman ve orman alanlarında dijitalleşme ile hassasiyet artışının daha düşük seviyelerde kaldığı belirlenmiştir. Ayrıca, raster veri üretiminde yeniden örnekleme yoluna gidilerek yükseklik değerleri tahmininde daha başarılı sonuçlar elde edilebileceği sonucuna ulaşılmıştır.
