Published: April 2023

Introduction and Aim: Cellular oxidative stress is responsible for various human diseases. Dietary antioxidant supplements from natural plants have good potential to reduce increased oxidative stress thus protecting from further medical complications. Genus Mucuna is well known for its promising health benefits. A common species of Mucuna, M. pruriens is being used for oxidative stress related diseases treatment. However, many species of this genus are not scientifically explored for their health-related beneficial properties. In the present study, we have made effort to investigate secondary metabolites composition and antioxidant potential in a Mucuna species namely M. sanjappae. In this work, we tried to understand superior system for secondary metabolites (total phenolics and flavonoids content) extraction and antioxidant activity in M. sanjappae seeds was demonstrated.
 
Methodology: Four different solvents viz., water, methanol, ethanol, and acetone in combination with four different extraction conditions (static, shaking, microwave and sonication) each with three different times have been studied. Total 48 extract samples were generated which were used for total phenolics, total flavonoids content along with antioxidant activity (DPPH, DMPD and FRAP) determination. Further major phenolics were identified using HPLC system.
 
Results: Water showed highest TPC and TFC level during microwave method for 120 seconds (81.627±0.728 mg GAE g-1 and 648.06±4.37 mg RUE g-1 respectively). The highest antioxidant activity was also found in M. sanjappae seeds extracted in water. RP-HPLC quantification of phenolics revealed tannic acid and gallic acid as predominant compounds. Correlation analysis indicated that the antioxidant of different extracted samples demonstrated a good positive relationship with TPC and TFC.
 
Conclusion: Present attempt indicated that, simple solvent water along with microwave method can be used for maximum antioxidants extraction from M. sanjappae seeds. This Mucuna species may be further studied to exploit as a natural antioxidant source in medicine and food etc.

Authors: Sikdar Sima , Sikdar (nee Bhakta) Mausumi
Published: April 2023

Recently, silver nanoparticles (AgNPs) hold a centre stage in the vast arena of research in nanomedicine. Biological methods of synthesis of nanoparticles are being adopted to avoid the use of chemicals that are toxic and hazardous and used in chemical synthetic methods. The choice of the plant extracts used for the synthesis of AgNPs is based on their phytochemicals and pharmaceutical properties. Another importance of the phytosynthesis method is that it is simple, easy, fast, reliable and cost effective. The phytochemical components of the herbal extracts not only cause reduction of Ag+1 to Ag0, but also increase the biological activities of the nanoparticles. This article briefly describes the research on green synthesis of AgNPs using Indian medicinal plant extracts. We aim to provide a systemic depth of information regarding the effect of various reaction factors during the synthesis of AgNPs such as the concentration of silver salt and phytoextract, light intensity, time, temperature, pH of the reaction mixture.  The characterizations of nanoparticles are done by X-ray diffraction, ultraviolet- visible spectroscopy, Fourier-transform infrared spectra, transmission electron microscopy, dynamic light scattering and zeta potential analysis. The phytochemicals and pharmaceutical activities present in the plant extracts are also reported here. The articles from 2011 to 2022 were selected and studied in detail to get in-depth knowledge about the phytosynthesis of AgNPs and their biological activities.

Authors: Abdul Hussein Jabbar Maryam , Khidhair Hussain Zainab
Published: April 2023

Introduction and Aim: Obesity and overweight refers to excessive buildup of fat in the body. Arthritis is a group of medical disorders associated with obesity and being overweight. Obesity associated with rheumatoid arthritis is more pronounced in women.  In this study, we aimed to evaluate some physiological and hematological parameters in obese women with arthritis.
 
Materials and Methods: This study included 90 women aged between 18 and 68 years. The women were divided into three groups based on their BMI as Obese (n=30), Obese+RA (n=30) and normal lean women as controls (n=30). Blood drawn from each participant was tested for their complete blood tests, lipid profiles, C-reactive protein reaction and presence of rheumatoid factor. Data was subjected to statistical analysis.
 
Results: Our study revealed the mean +SE for age, WHR and BMI to be elevated in women in the obese as well as Obese+RA groups and to be significantly higher in comparison to women in the control group. Except for HDL, all the other lipid parameters were seen elevated in the obese and Obese+RA group and showed significant difference from the control group. Similarly, among the complete blood count indices only ESR, WBC and PLT were found to be significantly elevated in obese and Obese+RA groups. The prevalence percentage for CRP and RF was seen to be highest in individuals belonging to the Obese+RA group.
 
Conclusion: Obese women as well as obese women with RA have elevated hematological and physiological parameters when compared to lean women.

Published: April 2023

Introduction and Aim: Breast cancer is the most prevalent sex-based malignancy worldwide. Nolvadex is commonly used as first-line therapy for patients with breast cancer. However, studies have indicated that long-term usage of this medicine can result in nephrotoxicity, which can damage kidney tissues. So, the aim of this research was to examine what happened to the serum levels of urea, uric acid, and creatinine when the drug was given to rats in a range of different doses.
 
Materials and Methods: Male Wistar rats (n=40) were randomly divided into four groups (n=10 each). The physiological solution (normal saline, 0.9%) was given to the control group (G1). Rats in Groups 2, 3, and 4 received Nolvadex at dosages of 30, 40, and 50 mg/kg of body weight four times weekly for a total of 10 weeks. At the end of the experimental period blood drawn from these animals were checked for serum concentrations of urea, uric acid, and creatinine. The animals were sacrificed and their kidneys subjected to histopathological examination. Data obtained was subjected to statistical analysis.
 
Results: The levels of urea, uric acid, and creatinine that were discovered in the experimental groups were all determined to be significantly higher than the levels that were discovered in the control group. In the experimental group that was given Nolvadex, an infiltration of inflammatory cells, blood congestion, pyknic and necrotic nuclei in the glomerulus, substantial epithelial deterioration in the renal tubules, and an altered renal tissue architecture were detected.
 
Conclusion: Serum levels of urea, uric acid and creatinine levels increased when experimental rats were administered with varying concentration of the drug Nolvadex. Its administration caused alteration to the architecture of renal tissue.

Published: April 2023

To increase the traction properties of a wheeled power vehicle, one of the classic solutions is to implement the entire weight load that falls on its propellers. The most rational and applied method in tractor construction is the 4K4 wheel formula, which allows the maximum weight of the tractor to be realized in the coupling. This is especially true when performing transport work in conditions where the implementation of traction properties largely depends on the condition of the base on which the movement takes place. When moving a transport unit on a horizontal surface, various additional methods of increasing traction properties are also known and widely used, often used of which are the installation of additional loads and increasing the contact area of the mover with the base on which the power vehicle moves (twin wheels, half-track, etc.). At the same time, when performing transport operations on roads with a significant longitudinal slope (ascent or descent) these methods of increasing the coupling weight are not always effective due to the unstable nature of the movement. This article presents experimental studies to improve the longitudinal stability of a tractor-transport unit (TTA) by using an original towing-distributing device, which allows simultaneously adjusting the longitudinal stability of the energy vehicle by redistributing the coupling weight inherent in the design characteristics in the tractor-transport unit system during its movement.

El objetivo fue realizar un análisis socioeconómico de las unidades de producción campesina (UPC) de la Reserva de la Biosfera Sierra de Huautla, Morelos (REBIOSH). Se realizó una tipología de UPC con los datos proporcionados del Censo Nacional Agropecuario en las 31 comunidades de la REBIOSH, para ello, se realizó un análisis de clúster y se aplicó estadística descriptiva para caracterizar cada uno de los grupos encontrados. La fase de campo consistió en entrevistas semiestructuradas aplicadas a 18 jefes de las UPC en seis comunidades de la REBIOSH. Se utilizó el estudio de caso para la obtención de información. Para el análisis socioeconómico se realizaron los cálculos microeconómicos propuestos por la metodología del diagnóstico agrario. Posteriormente se calcularon los umbrales de reposición económica que fueron, el salario mínimo de la región, línea de pobreza extrema por ingresos y línea de pobreza por ingresos. Se encontraron cinco grupos, diferenciados por la cantidad de ganado disponible como elemento principal. Los grupos I y II no rebasaron ninguno de los umbrales, el Grupo III solamente logró alcanzar el salario mínimo, y los grupos IV y V superaron estos tres umbrales. Se concluye que la ganadería es un elemento que potencia el ingreso familiar y de esa manera se superan los umbrales de pobreza, por tanto, los sistemas agroforestales son un elemento para lograr superar la pobreza en que viven las comunidades de la REBIOSH.

Global Shifts and Local Actors
Authors: Van Nederveen Meerkerk Elise , Boter Corinne , Carmichael Sarah , Frederick Katharine
Published: April 2023

The location of major textile manufacturing centres has shifted several times over the past 250 years, from Asia to Europe and the us, then back to Asia. Mainstream explanations for these shifts take a macro-approach and hence oversimplify the mechanisms behind them. We investigate these mechanisms at the micro-level of the household to gain a deeper understanding of the relocations of textile production worldwide. We do so by studying Dutch and Javanese households’ productive and consumptive behaviour in the period 1820-1940, when colonial relations between these two regions played an important role. We show that households’ labour allocation, livelihood strategies, and consumption preferences are crucial to understand the interaction between global shifts and local actors.
Influence of Participative Leadership Style on Public Health Service Delivery in County Governments in the Western Kenya Region

Published: April 2023

Poor health service delivery has been linked to the devolution of health services, with some health workers walking off the job due to inadequate pay and unsafe working conditions. This research aimed at establishing the influence of participative leadership style on public health service delivery by county governments in the Western Kenya region. Taking a positivist approach, the study was anchored on participative leadership theory. Descriptive survey and causal-comparative research designs were adopted with a target population of 966 personnel consisting of the CECMs, Chief Officers, Directors, and County Nursing Officer for Health, Medical Superintendents, Hospital Administrator, Human Resource Officer, Head of Pharmacy, Head of Nursing, Health Records Information Officer, Head of Laboratory, Head of Clinical Services and number of patients admitted, treated and discharged drawn from all four counties of Bungoma, Busia, Kakamega, and Vihiga. Primary data was collected using both structured questionnaires and interview schedules. Qualitative data was analysed by content analysis while quantitative data was analysed using both descriptive and inferential statistics. The SPSS Software version 26 was used for statistical analysis which was both descriptive whereby frequencies, percentages, means, and standard deviation were clearly shown in the form of both tables, models and charts. The hypothesis tested for significance of the study at 5% significance level. From the results, the beta value for participative leadership from the regression model was 0.777 at p<0.05. Participative leadership explains 60.4% (R2 =0.604) of the variance in public health service delivery. Therefore, the hypothesis was rejected. The study recommends establishing transparent and straightforward policies and procedures for managing human resources, which are essential for promoting productivity, equity, and workplace peace. In order to improve service delivery, the report suggests that county governments implement methods to promote collaborative decision-making. Consultation is a necessary part of the decision making process. In this regard, as many of the perspectives of workers who are directly affected by the decision as are feasible should be considered.
Quantifying the seasonal variations and regional transport of PM2.5 in the Yangtze River Delta region, China: Characteristics, sources, and health risks

Abstract. Given the increasing complexity of the chemical composition of PM2.5, identifying and quantitatively assessing the contributions of pollution sources has played an important role in formulating policies to control particle pollution. This study provides a comprehensive assessment between PM2.5 chemical characteristics, sources, and health risks based on sampling data conducted over one year (March 2018 to February 2019) in Nanjing. Results show that PM2.5 exhibits a distinct variation across different seasons, which is primarily driven by emissions, meteorological conditions, and chemical conversion of gaseous pollutants. First, the chemical mass reconstruction shows that secondary inorganic aerosols (SIA, 62.5 %) and carbonaceous aerosols (21.3 %) contributed most to the PM2.5 mass. The increasing oxidation rates of SO2 and NO2 from summer to winter indicate that the secondary transformation of gaseous pollutants is strongly positively correlated with relative humidity. Second, the positive matrix factorization (PMF) method shows that identified PM2.5 sources include SIA (42.5 %), coal combustion (CC, 22.4 %), industry source (IS, 17.3 %), vehicle emission (VE, 10.7 %), fugitive dust (FD, 5.8 %) and other sources (1.3 %). The Hybrid Single Particle Lagrangian Integrated Trajectory (HYSPLIT) model and the concentration-weighted trajectory (CWT) analysis are used to further explore different spatial distributions and regional transport of sources. High emissions (10-11 μg·m−3) of SIA and CC distribute in Nanjing and central China in winter. Moderate emissions (8-9 μg·m−3) of IS and VE are potentially located in the north of Jiangsu, Anhui, and Jiangxi. The PM2.5 pollution from long-range transport is attenuated by meteorological conditions and ocean air masses. Finally, the health risk assessment indicates that the carcinogenic and non-carcinogenic risks of toxic elements (Cr, As, Ni, Mn, V, and Pb) mainly come from IS, VE, and CC, which are within the tolerance or acceptable level. Although the main source of pollution in Nanjing is SIA at present, we should pay more attention to the health burden of vehicle emissions, coal combustion, and industrial processes.
On the importance to consider the cloud dependence in parameterizing the albedo of snow on sea ice
Authors: Foth Lara , Dorn Wolfgang , Rinke Annette , Jäkel Evelyn , Niehaus Hannah
Published: April 2023

Abstract. The impact of a revised snow surface albedo parameterization, which explicitly considers the cloud dependence of the snow albedo, is evaluated in simulations of a coupled regional climate model of the Arctic. The revised snow surface albedo parameterization leads to a more realistic simulation of the variability of the surface albedo during the snow melt period in late May and June. In particular, the reproduction of lower albedo values under cloud-free/broken-cloud conditions during the snow melt period represents a major improvement and results in an earlier disappearance of the snow cover and an earlier onset of sea-ice melt. In this way, the consideration of the cloud dependence of the snow albedo results in an amplification of the two-stage snow-albedo/ice-albedo feedback in the model. This finds expression in additional loss of sea-ice volume of more than 1000 km3 and additional reduction of summer sea-ice extent of around 250,000 km2 during one melting period, with accumulating magnitude of the overall changes in subsequent years.
Extremely Warm European Summers driven by Sub-Decadal North Atlantic Heat Inertia
Authors: Hellmich Lara , Suarez-Gutierrez Laura , Matei Daniela , Müller Wolfgang A.
Published: April 2023

Abstract. The internal variability of European summer temperatures has been linked to various mechanisms on seasonal to sub- and multi-decadal timescales. We find that sub-decadal time scales dominate summer temperature variability over large parts of the continent, and the mechanisms controlling such sub-decadal variations remain unexplored. Extremely warm summers occurring in sub-decadal periods when abnormally warm summer temperatures conglomerate are controlled by a strengthening of the subtropical gyre, an increase of heat transport, and an accumulation of heat content several years prior to an extremely warm European summer, thereby affecting ocean-atmosphere heat fluxes during extreme summers. This leads to a weakening and northward displacement of the jet stream and increased probability of atmospheric blocking over Scandinavia. Our findings link the occurrence of extremely warm European summers to the inertia of the North Atlantic, whose potential to improve the predictability of extremely warm summers several years ahead is of great societal interest, especially in a warming climate.

Abstract. An innovative tool for modelling specific flood volume was presented, which can be applied to assess the need for stormwater network modernisation as well as for advanced flood risk assessment. Field measurements for a catchment area in Kielce, Poland were used to apply the model and demonstrate its usefulness. This model extends the capabilities of recently developed statistical and/or machine learning hydrodynamic models developed from multiple runs of the U.S. EPA’s Storm Water Management Model (SWMM) model. The extensions enable inclusion of: 1) characteristics of the catchment, and its stormwater network, calibrated model parameters expressing catchment retention and the capacity of the sewer system, (2) extended sensitivity analysis and (3) risk analysis. Sensitivity coefficients of calibrated model parameters include correction coefficients for percentage area, flow path, depth of storage, impervious area, Manning roughness coefficients for impervious areas, and Manning roughness coefficients for sewer channels. Sensitivity coefficients were determined with regard to rainfall intensity and characteristics of the catchment and stormwater network. Extended sensitivity analysis enabled an evaluation of the variability of the specific flood volume and sensitivity coefficients within a catchment, in order to identify the most vulnerable areas threatened by flooding, Thus, the model can be used to identify areas particularly susceptible to stormwater network failure and the sections of the network where corrective actions should be taken to reduce the probability of system failure. The developed simulator to determine a specific flood volume represents an alternative approach to the SWMM model that, unlike current approaches, is calibratable with limited topological data availability, therefore generates a lower cost due to the less amount and specificity of data required.

Correlations between the amount of precipitation in the Lena and Yana river basins in winter and the ice coverage of the Laptev and East Siberian seas near the New Siberian Islands in the spring-summer period are studied based on the GLORYS12v.1 and ERA5 global reanalyses and archival meteorological data. A statistically significant correlation (with a confidence level of at least 0.95) was established in the certain parts of the study area. The Yana basin winter precipitation was found to have the highest correlation with the ice coverage in May. The correlation between the Lena basin precipitation and the ice coverage in July is lower, but also significant. During the other months, no significant correlations were revealed. The established facts may be of practical use for long-range forecasting of ice conditions near the New Siberian Islands at the beginning of the summer navigation along the Northern Sea Route.

Published: April 2023

The purpose of this article is to make a legal and economic balance of the corporate types provided for in the Civil Code after twenty years of its approval by law 10.406/2002. In order to reach the objective, the research started with an economic explanation revealing the process by which agents choose a certain form of structure admitted by the legal system to maximize their own interests. Next, the types of society were dealt with, having as an epistemological cut the personified corporate types and the residual liability of the partners. Finally, there was the issue of the revocation of the Limited Liability Individual Company and the problem of its revocation in law 14.195/2021 and by law 14.382/2022. To reach the scope, the research sought to carry out a bibliographic review on the subject, as well as using a quantitative methodology, through the analysis of statistical data extracted from official sources. The research converges to demonstrate that societies are instruments that stimulate entrepreneurial initiative and actively contribute to the country’s economic development. In a predictive character, through an economic rationality, there is a need to discontinue types that do not ensure the protection of private investment, as is the case of simple partnerships, in collective name, limited partnership and limited partnership by shares, as well as the creation of a general part of corporate law applicable to business companies.

The growing use of artificial intelligence in the most diverse segments of society sparks the debate about the risks to fundamental rights involved in the use of technology. Simultaneously, the scientific uncertainties that hang over the functioning of algorithms are raised as obstacles to the regulation of technology. In this context, this article uses a legal-dogmatic methodology to explore the hypothesis that the precautionary principle, already consolidated in other branches of law, is also an alternative to risk mitigation in the use of artificial intelligence systems.
Feminización de personajes masculinos en dos montajes contemporáneos de tragedias griegas: el Prometeo de Carme Portaceli y el Creonte de Miguel del Arco
Authors: Cuevas Caballero Marta
Published: April 2023

En la Antigüedad clásica, donde el teatro era un ámbito masculino, se producía un desdoblamiento de género: un dramaturgo varón escribía un personaje femenino, con un discurso convencionalizado para reflejar, desde una perspectiva masculina, la idea de la feminidad imperante en la sociedad. Dicho personaje era luego interpretado por un actor varón, que abrazaba la contradicción de que dicho personaje femenino proyectara una visión negativa de la sociedad patriarcal. En este artículo se analiza un montaje de estética contemporánea, Prometeo (2010) de Carme Portaceli, y otro de ambientación atemporal, Antígona (2015) de Miguel del Arco. Se estudia, en particular, la transgresión de las convenciones dramáticas sobre género en la tragedia griega, y la transformación dramatúrgica de personajes masculinos en personajes femeninos, para observar qué sucede en la actualidad, y qué se quiere transmitir desde el escenario, cuando hay mujeres interpretando papeles tradicionalmente masculinos. Puede usarse esta perspectiva de género para actualizar la tragedia introduciendo una lente feminista reivindicativa, como en Prometeo, o se puede feminizar el personaje para reformular, como en Antígona, el conflicto de género, subrayando otros.
New evidence for the dating of Palladas and Eutolmius Scholasticus Illustris
Authors: Benelli Luca
Published: April 2023

Kevin Wilkinson has identified clues in the text of epigrams by Palladas which in his view enable us to date this poet to the age of Constantine, earlier than had previously been assumed. He seeks to prove this new chronology with the help of a papyrus (P. Ct. YBR inv. 4000) which he attributes to Palladas. Scholars however have challenged the attribution of the papyrus and refuted Wilkinson’s new chronology for Palladas. More recently, Wilkinson tried to defend his hypothesis with the help of an epigram by Palladas (AP 6.85), which supposedly mentions a Roman military-administrative title (-πριλάριος) that was abolished at the start of the fourth century CE. The present article will propose a new interpretation for AP 6.85: departing from Wilkinson’s arguments about -πριλάριος, it will be demonstrated that Gordioprilarios is in fact the early fourth century military saint Gordius, mentioned for the first time in a homily (nr. 18) of 370-378 CE by St Basil, and that the Timothy of the epigram is the Alexandrian patriarch of ca. 381-385 CE. It may thus be inferred that Palladas was still alive after 370 CE. The article will also demonstrate that the AP-poet Eutolmius Scholasticus Illustris is in fact Flavius Eutolmius Tatianus.
Días de vino y vasos: mujeres y fiesta en la cer´ámica ática de figuras rojas
Authors: Díez Platas Fátima
Published: April 2023

Esta contribución pretende proponer una mirada interpretativa a las escenas representadas en el conjunto de estamnos áticos de figuras rojas de mediados del siglo V a. C. que se encuadran dentro de los conocidos  como “vasos de las Leneas”.  La lectura que se propone tiene en cuenta los análisis y las interpretaciones del grupo de vasos realizados desde el primer trabajo de Frickenhaus (1912) que estableció el corpus de estudio e introdujo la debatida cuestión de la identificación de las escenas como representación de la fiesta ateniense de las Leneas. Dejando de lado el debate de la identificación concreta de la fiesta en la puesta en escena figurativa de un conjunto de imágenes de indudable corte dionisiaco  e identificable tono ciudadano, la propuesta interpretativa se centra en los protagonistas de las escenas -los vasos y las mujeres-, en la relación entre los elementos figurativos y en el modo de representación y narración visual para intentar desentrañar un tipo de escena dionisiaca encuadrada en una clase determinada de vasos con unos destinatarios concretos.
Michael Field's Paratextual Poetics: Portraying a Protomodernist Sappho
Authors: Cantillo Lucuara Mayron Estefan
Published: April 2023

This article offers an innovative perspective on Katharine Bradley and Edith Cooper’s Long Ago (1889), their Sapphic volume of verse published under the Michael Field pseudonym. Rather than propounding new interpretations of the lyrics in the collection, I focus on its paratextual apparatus –from the cover and the frontispiece to the endnotes or appendix– with the aim of unveiling a significant aspect that has been overlooked by most critics: the fact that, in its rich paratextuality, Long Ago possesses an effective illocutionary force that seduces the reader, pre-establishes a clear interpretive framework, and activates an innovative dialogue with the past. This paratextual dialogue, I conclude, results in a protomodernist reworking of Sappho as an enigmatic, unstable, and radically open (para)textual figure –one that is always ready to be made new.

Método: se presenta un estudio piloto de diseño correlacional trasversal elaborado en dos fases: 1) creación del cuestionario del miedo a la recurrencia del cáncer (CMRC) y de la Escala General del Miedo a la Recurrencia del Cáncer (EGMRC); 2) evaluación de sus propiedades psicométricas. Resultados: para la elaboración de los cuestionarios se utilizó el acuerdo entre expertos medido por la V de Aiken. El CMRC queda finalmente configurado con 8 ítems que se responden con una escala tipo Likert de 0-4 y un Alfa de Cronbach de 0,85. La EGMRC de una sola pregunta que se responde con una escala de 0-100 correlaciona hasta un 0,84 con el CMRC. Se utilizó una muestra de 50 mujeres supervivientes de cáncer ginecológico seleccionadas en el Hospital Universitario Clínico San Carlos de Madrid. Ambas escalas correlacionan con el nivel de ansiedad de las pacientes y la función emocional de calidad de vida. No se hallan correlaciones con los niveles de depresión. Conclusiones: El CMRC y la EGMRC son dos instrumentos que pueden ser válidos para la evaluación del miedo a la recurrencia del cáncer en pacientes supervivientes de cáncer ginecológico.

Mục tiêu: Xác định nồng độ magiê (Mg) huyết tương và đánh giá mối liên quan giữa nồng độ Mg huyết tương với bệnh cảnh lâm sàng ở bệnh nhân nhiễm khuẩn huyết. Đối tượng và phương pháp: Nghiên cứu mô tả tiến cứu trên 125 bệnh nhân nhiễm khuẩn huyết điều trị tại Bệnh viện Trung ương Quân đội 108 từ tháng 11/2019 đến tháng 02/2021. Nồng độ Mg huyết tương được đo tại thời điểm vào viện (Mg1) và tại thời điểm ngày 3 (Mg3) sau vào viện, theo dõi sống sót và tử vong 30 ngày. Kết quả: Tỷ lệ thiếu Mg1 là 48,8%. Nồng độ Mg1 và Mg3 tương ứng là 0,70 (0,6-0,81) và 0,75 (0,65-0,85)mmol/L, p=0,001. Điểm SOFA ở nhóm thiếu Mg1 cao hơn nhóm không thiếu (8,48 ± 4,06 điểm và 6,8 ± 3,92 điểm, p<0,05). Nồng độ Mg1 ở nhóm sốc thấp hơn nhóm không sốc (0,65 (0,57-0,73) mmol/L và 0,75 (0,67-0,87) mmol/L, p<0,001). Không có sự khác biệt về nồng độ Mg1 giữa nhóm thở máy và nhóm không thở máy, giữa nhóm suy thận và không suy thận, giữa nhóm suy gan và không suy gan, giữa nhóm tử vong 30 ngày và nhóm sống. Kết luận: Thiếu Mg1 hay gặp ở bệnh nhân nhiễm khuẩn huyết. Nồng độ Mg1 thấp hơn Mg3. Nhóm thiếu Mg1 có điểm SOFA cao hơn nhóm không thiếu. Nhóm sốc nhiễm khuẩn có nồng độ Mg1 thấp hơn nhóm không sốc. Không có sự khác biệt nồng độ Mg1 giữa nhóm tử vong và nhóm sống 30 ngày.
Impacts of microaggressions and neo-racism on international students' sense of belonging
Authors:   University of Massachusetts Lowell, McVickar Allyson
Published: April 2023

This study explored international student sense of belonging within three state universities in New England and found a concurrent theme of microaggressions and neo-racism on their campuses that has affected their sense of belonging. Despite trends in the international higher education literature that have historically investigated ways to improve the academic experiences and engagement of international students, the findings indicate less attention has been paid to the sense of belonging felt by these students, particularly how microaggressions and neo-racism affect their sense of belonging. Microaggressions, or subtle verbal or nonverbal insults directed towards people of color, often unconsciously (Solorzano et al., 2000), were a common experience of international student participants and frequently mentioned in communications with faculty, domestic students, and staff participants. Suggestions for best practices in fostering international student sense of belonging for higher education professionals and practitioners are also discussed.
Türkiye’de Fitness Dergi Reklamlarında İnsan Bedeninin Sunumu

Published: April 2023

Günümüzde birçok şey tüketim metasına dönüşmektedir. İnsan bedeni bu dönüşümden etkilenerek, tüketim aracına dönüşen bir boyut kazanmaktadır. Özellikle reklamlar, “arzulanan” insan bedeni imgeleri oluşturulmak maksadıyla kullanılmaktadır. Nitekim fitness dergi reklamlarının temel vaadini oluşturan unsur, arzulanan, fit ve sağlıklı bir bedene kavuşma gerekliliğidir. Çalışmanın temel amacı Türkiye’de yayın yapan fitness dergilerindeki reklamlarda insan bedeni tasvirlerinin nasıl gerçekleştiğini gözler önüne sermektir. Çalışmanın ana çerçevesini Erving Goffman’ın “Gender Advertisements” (1976) isimli eserinde geliştirdiği ve reklamlardaki cinsiyet rollerini betimlediği araştırması oluşturmaktadır. Literatürde insan bedeninin sunumu ile ilgili yapılan diğer araştırmalarda kullanılan ölçütler sentezlenerek yeni bir çözümleme tablosu elde edilmiştir ve bu doğrultuda içerik analizi gerçekleştirilmiştir. Reklamlar, tarama modelleri içerisinden genel tarama yönteminin bir alt basamağı olan “Kesitsel Araştırmalar Yöntemi” ile belirlenmiştir. Çalışmadan elde edilen bulgular sonucunda Lebre’nin (2005) çalışmasında olduğu gibi erkeklerin kaslı ve esnek bir şekilde betimlendiği görülmektedir. Bunun yanı sıra Bell ile Milic’in (2002), Goffman’ın teorisinin geçerli olduğuna dair sonuçlara yer verdikleri araştırma ile benzer bulgulara da ulaşılmıştır. Ayrıca bulgular Belknap ile Leonard II’in (1991) Goffman’ın cinsiyet rollerine yönelik oluşturduğu altı kategori çerçevesinde incelediği araştırma ile bazı konularda uyuşmaktadır. Buna göre kadınların baktığı yön ile ilgili tespit edilen sonuçlar, Bell ile Milic’in bulguları ile örtüşürken, Goffman’ın bulguları ile uyuşmamaktadır.

Published: April 2023

Günümüzde yaşanan yoğun rekabet ortamında sürdürülebilirlik çalışmaları, markaların rakiplerinden farklılaşabilmesini sağlamada büyük önem kazanmıştır. Sürdürülebilirlik faaliyetlerinin başarısının, kurumsal sosyal sorumluluk ve yenilikçilik uygulamalarının kullanılmasıyla doğrudan ilgili olduğu görülmektedir. Tekstil ve hazır giyim sektöründe faaliyet gösteren markaların da son zamanlarda sürdürülebilirlik, yenilikçilik ve kurumsal sosyal sorumluluk gibi faaliyetlere daha fazla önem verdiği görülmektedir. Markaların yapmış oldukları bu faaliyetlere yönelik tüketicilerin algı ve yaklaşımlarını tespit etmek bu çalışmanın temel motivasyonunu oluşturmaktadır. Bu çalışmada, markaların sürdürülebilirlik çerçevesinde yaptığı faaliyetlerin, işletmelere sağladığı faydalar irdelenmiş olup tüketici perspektifinden algılanan kurumsal sosyal sorumluluğun ve algılanan yenilikçiliğin marka imajına, marka imajının da davranışsal niyet üzerindeki etkilerinin ne yönde olduğu araştırılmıştır. Bu bağlamda Ankara’da bulunan bir üniversitede öğrenim gören öğrencilere anket uygulanarak saha araştırması yapılmıştır. Araştırma modelinde yer alan değişkenler için korelasyon ve regresyon analizlerinden yararlanılmıştır. Araştırma sonucunda tüketicilerin sürdürülebilir giyim markalarından algıladığı kurumsal sosyal sorumluluğun ve yenilikçiliğin marka imajına, marka imajın ise davranışsal niyet üzerine pozitif etkisi olduğu tespit edilmiştir.

Published: April 2023

This study analyzes the differences in importance and implementation level for the detailed tasks of the fourth(2018-2022) basic plan for lifelong education promotion. To this end, a needs analysis has been conducted targeting 19 persons involved in lifelong education for 44 detailed tasks within the basic plan. For the analysis, the t-test, Borich need assessment model, and Hershkowitz's criticality function were used. As a result of the analysis, 13 policy tasks had high levels of both importance and implementation (e.g. support for career-interrupted women, expansion of support for literacy education to all citizens who wish). Eight policy tasks were recognized as highly important, but the actual implementation is low (e.g., support for career planning consulting during the transition period of life, securing investment in lifelong education at the national level), while 13 tasks rated low at the important level, but the level of implementation is high (e.g. the elderly customized learning support, expansion of learning support for multi-cultural families) with 10 tasks with low levels of importance and implementation (e.g. expansion of paid study leave system, development and utilization of learning ability diagnosis tools for adults). Based on this, we identified policies that should be given more attention in terms of implementation in the 5th Basic Plan, and discussed tasks that should be considered when establishing the future 6th Basic Plan. We also provided implications for the future.
Local Government Response to the COVID-19 Pandemic in Bangladesh: Challenges and the Way Forward
Authors: Chowdhury Mahtab Uddin , Shaoun Saharin Priya
Published: April 2023

COVID-19, as an emerging catastrophe, posed unprecedented challenges with global socio-economic, political, and policy ramifications. Being a densely populated country, Bangladesh has seen the effects of the pandemic since March 2020. As a democratic republic, the local government system (LGS) is expected to play a significant role in governance to deal with this immeasurable crisis requiring a comprehensive governmental action plan. This research aims to investigate the country's local government system during the pandemic. Generally, the government struggled immensely to cope with the challenges it had to face. As an integral part of the state structure, LGS also faced numerous challenges for various reasons, including financial, political and policy limitations in tackling the crisis. The study found an absence of cooperation, coordination, and communication between the central government and local bodies. There were also difficulties with transparency and accountability that needed to be addressed correctly. Under these circumstances, the study will aim to demonstrate the country's local government responses to the pandemic. The research will follow a qualitative approach using secondary data and case study-based analysis.
