Türkiye'de Başörtülü Kadının Medyadaki Temsili
Authors: Besinci Simsek Ebrar
Published: May 2024

Medyanın birey ve toplum üzerinde güçlü tesirinin olduğu, yasama, yürütme ve yargı organlarıyla birlikte adeta dördüncü bir güç olarak kabul edildiği bilinmektedir. Gelişen teknolojiyle birlikte medyanın etkinliği artmış, toplumsal yapı ve pratiklerin önemli bir sahasını oluşturmuştur. Buradan hareketle literatürde sıkça tartışılan bir konu da, toplumsal gerçeklikleri yansıtmada önemli bir aracı olan temsillerin medya tarafından ne kadar gerçekçi ve yeterli bir şekilde yansıtıldığı olmuştur. Bu bağlamda, çeşitli çalışmalarda televizyon gibi medya aygıtlarındaki temsillerle toplumsal gerçeklik arasındaki uyuşmazlıkların çok fazla tartışıldığı görülmüştür. Binaenaleyh Türk medyasında da geniş kitlelerin kısıtlı veya çarpıtılmış bir şekilde temsil edildiği veya hiç temsil edilmediği gözlemlenmiştir. Özellikle %99'u Müslüman olan ülkemizde dini ritüellere önem veren kesimlerin eksik veya yanlış temsil edildiği görülmektedir. Bu çalışma, geleneksel medyadaki başörtülü kadın temsili üzerine odaklanarak, medyanın toplumsal gerçekliği yeterince yansıtamadığı tezini araştırmayı amaçlamaktadır. Başörtülü kadının televizyondaki temsili, içerik analizi ve betimsel analiz yöntemi kullanılarak ele alınmıştır. Araştırma kapsamında ulusal çapta yayın yapan ana akım medyanın dizileri ve tematik haber kanallarının yayın akışları incelenmiştir. Ancak, temsillerin oranı yalnızca bir faktör değildir; ayrıca, temsil edilen gruplara biçilen saygı ve rol de önemlidir. Bu kapsamda Gerbner'in "ekme teorisi"nin çerçevesi çizilmiş ve elde edilen bulguların ardından, ortaya çıkan resmin sebepleri detaylı bir şekilde tartışılmıştır.
Las dos caras del Síndrome de Down en el discurso publicitario peruano
Authors:   , Coral Rios Gerson
Published: May 2024

La finalidad de esta investigación es analizar cómo perciben los docentes del nivel primario de colegios de Lima la representación de menores con Síndrome de Down entre los rangos de edades de 6 a 12 años en el discurso publicitario de la categoría escolar en la campaña “Todo Cambia Contigo” de la Sociedad Peruana de Síndrome de Down. Se utilizó una metodología de herramienta cualitativa basado en estudio de casos, empleando la técnica de entrevistas a profundidad. Se llevaron a cabo 17 entrevistas semiestructuradas a docentes de nivel primario de colegios de Lima que hayan tenido como mínimo una experiencia enseñando a un niño con Síndrome de Down. Como resultado, se observó que este tipo de campañas, no favorecen a la comunidad de niños con Síndrome de Down en el sector educativo, puesto que no reflejan la realidad de estos niños en la sociedad peruana, siendo estas campañas contraproducentes para las marcas. En este sentido, los hallazgos sirvieron como punto de inicio para tener un mejor conocimiento sobre la problemática de los prejuicios del Síndrome de Down y su realidad en la sociedad peruana en el sector educativo, para que de esta manera se apliquen estrategias publicitarias de una forma correcta en las campañas donde se quieran incluir a niños con Síndrome de Down y que su representación sea más real volviendo a la marca más genuina.

El objetivo de este estudio es “obtener cemento geopolímero para la elaboración de shotcrete a partir de la activación alcalina de relaves mineros”, con la finalidad de mejorar la resistencia a la compresión, el endurecimiento y la fluidez del shotcrete utilizado para el sostenimiento de labores subterráneas. Para ello, se emplearán activadores alcalinos como el silicato de sodio (Na₂SiO₃) e hidróxido de sodio (NaOH). De igual forma, para definir las características mecánicas que se obtienen en el shotcrete a partir de cementos geopoliméricos con concentraciones de NaOH de 12 y 15 molarity (M), se realizan ensayos estandarizados para definir las resistencias a compresión del hormigón proyectado sobre probetas cilíndricas. Los resultados alcanzados incluyen el potencial de cemento ecoeficiente con una resistencia a la compresión de hasta 19 MPa después de 28 días, hasta un 73% de reducción de emisiones de CO2 de la producción de cemento Portland, e incluyen alternativas sostenibles al uso de los relaves. Por lo tanto, se plantea desarrollar cementos geopoliméricos sostenibles utilizados como materiales para la producción de shotcrete proyectado con mejores propiedades.
Continuity vs. Discontinuity: A Case of Home Language and Literacy Socialization in Indonesia
Authors: Hamida Layli , Patria Aditya Nur , Reswari Girindra Putri Ardana
Published: May 2024

The present study explores the language and literacy socialization (LLS) of Indonesian children from low- to middle-income families. The Indonesian government has never truly involved home and family as the base for literacy socialization in its programs, affecting the nation-state's low rank in literacy proficiency. This paper aims to describe the LLS of low- to middle-income Indonesian families and examine how the language used by caregivers and parents stimulates the issue of continuity or discontinuity between home and school literacy practices. The study used an ethnographic approach in which the researchers observed the LLS events of 6 families in Surabaya, Indonesia. Conversations between caregivers/parents and children during literacy events were recorded. The findings suggest that every family has different patterns of literacy practices depending on their beliefs and culture at home and that parents' or caregivers' language and style of communication may facilitate or hinder children's access to literacy. Two socialization patterns were identified, including reference to past experience and collaborative negotiation of meaning. It is argued that not only the background of education but also caregivers' literacy culture and educational beliefs play a role in their strategy of language and literacy socialization at home.

Authors: Yıldırım Fatma
Published: May 2024

Tarihte insanlar çeşitli yollardan mülk edinmişlerdir. Bu yollardan biri de hibedir. Hibe karşılıksız vermek, bağışlamak anlamlarına gelmektedir. Kadın erkek fark etmeksizin ehliyet sahibi olan herkes malını ister aile içi akraba ister yabancı kişiler olsun istediği kişiye hibe edebilmektedir. Bütün toplumlarda hibe çeşitli isimler altında gerçekleşmiştir. Osmanlı Devleti’nde de hibe uygulamaları yaygın olarak görülmektedir. Hibeler genellikle Osmanlı şehirlerinde kadılar tarafından tutulan Şer’iyye sicillerine kaydedilmiştir. Burada da Osmanlı Devleti’nin bir şehri olan Ayıntâbda Hicri 1008,1009-1061/Miladi 1600-1650 tarihleri arasındaki hibe kayıtları incelenmiştir. Bu kayıtlarda hibelerin yapılma amaçlarından bahsedilmemektedir. İlgili kayıtlarda genellikle hibelerin kimden kime yapıldığı, hibe konusu, hibe edilen malın türü ile ilgili bilgiler yer almaktadır. Aynı zamanda yapılan bu hibelerin bazıları mirasçılar tarafından kabul görmediği için taraflar arasında davalaşmalar yaşanmasına neden olmuştur. Bu çalışmada XVII. yüzyılın ilk yarısındaki kayıtlardan hareketle Ayıntâb şehrindeki hibe uygulamaları hakkında bilgiler verilerek hibelerin tarafları, hibeden dönülüp dönülemeyeceği ve şehirde yapılan hibeler üzerine mahkemeye yansıyan davalaşmalar değerlendirilmeye çalışılacaktır.

Published: May 2024

Blockchain technology, which is impossible for people and businesses to ignore and brings great changes at the sectors where it is used, contributes to the solution of many problems at businesses. However, it has not been applied in the field of supply chain and logistics to the expected extent and there are the limited number of studies in the literature on this subject compared to other fields. In this context, the aim of the study is to explain blockchain technology in detail, to ensure that the technology is fully recognized, to create awareness on businesses by explaining its benefits with examples of use in supply chain and logistics activities, and to contribute to later researchers by identifying the gaps in the literature by analyzing the literature. As a result of the exploratory research, it was determined that blockchain technology contributes to the solution of many problems, especially reliability, cost, flexibility, delays, transparency, and low performance. Considering the result of the literature analysis, it has been concluded that academic studies on blockchain technology in the field of supply chain and logistics are not sufficient, and the number of these studies should be increased in order for the technology to be learned and used by more businesses in the relevant field.
Yalvaç Müzesi’nden Montanist Olarak Yorumlanan Bir Mezar Stelinin Yeniden Değerlendirilmesi
Authors: Özhanlı Mehmet , Kahraman Fatma
Published: May 2024

Çalışmaya konu olan mezar steli, Yalvaç Müzesi’nin bahçesinde sergilenmektedir. Stel, D. M. Robinson tarafından, 1924 yılında Yalvaç’ta bir evin merdiveni altında bulunmuş ve yayımlanmıştır. Alınlıklı, naiskos tipli mezar stelinin üzerinde, alınlıkta Medusa başı ve naiskosun içerisinde altıgen bir altlık üzerinde mezar sahibi olan kadının büstü betimlenmiştir. Yerel ustalar tarafından yapılmış olan steldeki kabartmalar, Antoninler Dönemi’nin sonlarına doğru ortaya çıkan saç modeli ve üslubuyla işlenmiştir. Yerel işçilik dikkate alınarak eser, Antoninler Hanedanlığı’nın Son Evresi’ne tarihlenmiştir. Stelin üzerindeki yazıtı yorumlayan D. M. Robinson, yazıtın son satırından yola çıkarak mezar sahibinin Montanist olduğunu iddia etmiştir. Montanizmle ilgili görüşler aktarıldıktan sonra çalışmaya konu olan eserin üzerindeki yazıtın Montanist bir ifade olup olmadığı tartışılmıştır. Yazıtta ve kabartmalarda Hristiyanlığı açıklayıcı ifadelerin bulunmamasından dolayı eserin pagan kültüre ait olduğu sonucuna varılmıştır. Antiokheia’nın Phrygia sınırında bulunması ve Phryg kültürü ile yoğrulmuş olmasından dolayı kent ve çevresinde Montanizmle ilgili verilerin ortaya çıkma ihtimali üzerine durulmuştur.

FCM-DETR: An Efficient End-to-End Fire Smoke and Human Detection based on Deformable DETR
Authors: Liang Tianyu , Zeng Guigen
Published: May 2024

Fire is a serious security threat that can lead to casualties, property damage, and environmental damage. However, despite the availability of object detection algorithms, challenges persist in detecting fires and smoke. These challenges include slow convergence speed, poor performance in detecting small targets, and high computational cost limiting deployments. In this paper, Fire smoke and human detection based on ConvNeXt and Mixed encoder (FCM-DETR), an end-to-end object detection algorithm based on Deformable DETR, is proposed. Firstly, we introduce ConvNeXt to take the place of Resnet, which greatly reduces the amount of computation and improves the ability to extract irregular flame features. Secondly, to effectively process multi-scale features, the original encoder is decoupled into two modules. Then Mixed encoder, an innovative encoder structure, is proposed, resulting in excellent performance of multi-scale fire and smoke features fusion. What can’t be overlooked is that the encoder block is compatible with any DETR-based models. Finally, the convergence speed is accelerated and the mean of average precision is improved by applying a novel loss function called Powerful IoU v2. The experimental results indicate that our model achieves the best detection accuracy compared to other models, with mAP reaching 66.7%, mAPs and Accuracyfire achieving impressive 50.2% and 98.05%, respectively.
Spatial Augmented Reality for Expanding the Reach of Individuals with Tremor beyond Their Physical Limits
Authors: Wang Kai , Wu Meng Jing , Sun Zhi , Huang Qun
Published: May 2024

Tremor is a prevalent neurological disorder characterized by involuntary shaking or trembling of body parts. This condition impairs fine motor skills and hand coordination to varying degrees and can even affect overall body mobility. As a result, tremors severely disrupt the daily lives and work of those affected, significantly limiting their physical activity space. This study developed an innovative Spatial Augmented Reality (SAR) system aimed at assisting individuals with tremor disorders to overcome their physical limitations and expand their range of activities. The system integrates eye-tracking and Internet of Things (IoT) technologies, enabling users to smoothly control objects in the real world through eye movements. It employs a virtual stabilization algorithm for stable interaction with objects in the real environment. The study comprehensively evaluated the system's performance through three experiments: 1) assessing the effectiveness of the virtual stabilization algorithm in enhancing the system's ability to assist individuals with tremors in stable and efficient interaction with remote objects; 2) evaluating the system's fluidity and stability in performing complex interactive tasks; 3) investigating the precision and efficiency of the system in remote interactions within complex physical environments. The results demonstrate that the system significantly improves the stability and efficiency of interactions between individuals with tremor and remote objects, reduces operational errors, and enhances the accuracy and communication efficiency of interactions.

Cassava Peel Chips as an Effort to Utilize Economic Value Waste in Keripik Selo Gedong MSME. Micro Small Medium Enterprise (MSME) Selo Gedong Chips has produced various chips, including cassava, banana, and bote. The obstacle is that cassava peel waste, which reaches 20% of the total cassava produced so far, has only been used as animal feed and has not been widely used for human consumption. Even though cassava peel still has the potential to be a healthy food because its fiber content is 15.20% (w/w). However, the high content of cyanide acid (HCN) (419.8 mg/kg) and its toxic nature is a weakness so it needs to be treated to reduce the toxicity. This activity aims to process cassava peel waste into cassava peel chips with economic value. To increase the selling value of the cassava peel chips, a cassava peel chip oil drainer was provided to increase the product's shelf life and attractive packaging was introduced for the cassava peel products. Based on the results of training in making cassava peel chips, soaking in salt for three days succeeded in reducing cyanide acid levels to a concentration suitable for consumption, namely 4.32 ppm. The formulations most preferred by the panelists were the balado flour and original flour formulations. One 80-gram package of cassava peel chips can be sold for IDR 6,500.00. Judging from the evaluation aspect, the enthusiasm of the training participants in making cassava peel chips has a high score. Apart from that, looking at the skill aspect, participants were able to produce cassava peel products that were safe to consume and crunchy with attractive packaging.

The use of Azolla microphylla (Azolla) as organic fertilizer or green manure is not yet known by the Farmer Group (FG) of Tani Mulyo 1 and Tani Mulyo 5. Moreover, dual system of Azolla is applied to organic rice cultivation. The dual system of Azolla uses Azolla as a fertilizer and as a deterrent to the growth of weeds that interfere with rice plants. This partnership program aims to increase partners' knowledge about the dual system of Azolla and assistance and direct practice of Azolla application on cultivated organic paddy fields. The stages include socialization, counseling, mentoring, practice of Azolla application, and monitoring-evaluation. The results showed that the participants' knowledge about Azolla before the activity was 25% very not know, 45% not know, and 15% know enough. There was an increase in participants' understanding after the activity, 65% know and 25% very know or increased up to 100% compared to before the activity. The results of participant satisfaction showed that 65% of participants were satisfied and 10% are very satisfied with the activities carried out. As many as 70% of the partners stated that they would apply the dual system of Azolla in organic rice cultivation. The increasing understanding and awareness of partners will affect the development of organic rice cultivation.

The demand for safe recreation conditions is growing every day. Therefore, hotels, lodges which acquire ecological characteristics, improving the interiors of the premises, the exterior of the territories, causing green areas and growing organic products, supporting the ideas of resource conservation and remediation of territories. The purpose of this article is to evaluate the most successful tourism eco-projects in Europe, to identify environmental criteria that attract vacationers and improve the quality of the environment, to evaluate the service, natural attraction and creativity of holiday destinations, to make a comparative description of hotels and resorts located in different natural areas. Service, proximity to nature and the satisfaction of visitors with interaction of nature, design of the exterior and interior, the availability of exclusive decor items, and non-standard leisure activities are the three important criteria for choosing a hotel or resort today. These three criteria were studied by the method of manual analysis of visitor reviews. Most often vacationers mention natural beauty, somewhat less often – service, and quite rarely – creativity in the design and organization of recreation. For the first time, the most successfully functioning ecological resorts in Europe are divided into groups by location and natural resources. The requirements for resorts that are popular among the visitors have been formed. The criteria of service, natural advantages and creativity in different groups are compared.
FEATURES OF RECEIVING THE GASOLINE FRACTION BY THERMAL PYROLYSIS OF POLYOLEFIN RAW MATERIALS
Authors: Shevchenko Kyrylo , Hryhorov Andrii
Published: May 2024

The article examines the peculiarities of the process of thermal pyrolysis of secondary polymer raw materials, aimed at obtaining a gasoline fraction - the basis for obtaining mixed or synthetic automobile gasoline. Based on the global experience of polymer processing, polyolefins represented by high-density polyethylene (HDLP) and polypropylene (PP) were chosen for the study. Thermal pyrolysis was carried out at atmospheric pressure (0.10-0.12 MPa) on a reactor-type laboratory installation with subsequent removal of the gasoline fraction (30-210 °C) from liquid pyrolysis products according to the ASTM D 86 method. It has been established that the temperature interval in which pyrolysis of polyolefin raw materials must be carried out is for HDLP - 400-430 °С (the maximum output of the gasoline fraction at 420 °С); for PP - 350-370 °C (maximum yield of gasoline fraction at 365 °C). By controlling the duration of thermal pyrolysis, it is possible to increase the yield of the gasoline fraction by an average of 15-17%, which must be taken into account during the industrial implementation and further operation of pyrolysis plants for polymer raw materials.
Increasing the temperature of the end of boiling of the gasoline fraction from 150 °С to 210 °С allows to increase its output by 9% (for HDLP) and by 12% (for PP). But at the same time, there is also an increase in the content of olefins in it (by 13-14%), which is a positive point from the point of view of resistance to detonation of the gasoline fraction, and a negative point - in view of its low chemical stability. The conducted studies showed that secondary polyolefin raw materials should be considered as an alternative to classic raw materials (oil and gas condensate), and the pyrolysis process as the main technological process for obtaining the gasoline fraction - the basis for obtaining commercial automobile gasoline. Prospective places for the implementation of this technology are both production sites of oil refineries and sites located in close proximity to places of accumulation of raw materials - ports, city landfills, special landfills.
Defining the Patient Acceptable Symptom State (PASS) for PROMIS After Total Ankle Replacement
Authors: Shaffrey Isabel , Nguyen Joseph , Conti Matthew , Cody Elizabeth , Ellis Scott , Demetracopoulos Constantine , Henry Jensen K.
Published: May 2024

Background:

Although patient-reported outcomes (PROs), such as the Patient-Reported Outcomes Measurement Information System (PROMIS), are a key element of evaluating success after total ankle replacement (TAR), many do not explicitly state a key factor of postoperative success: is the patient satisfied with their outcome after TAR? The patient acceptable symptom state (PASS) represents the symptom threshold beyond which patients consider themselves well. This study aimed to establish the PROMIS thresholds for the PASS in a primary cohort of TAR patients.

Methods:

This single-institution study included 127 primary TAR patients with preoperative and 2-year postoperative PROMIS scores. At 2 years postoperatively, patients answered 2 PASS anchor questions (Satisfaction, Delighted-Terrible scale) with Likert-scale responses. PASS thresholds with 95% confidence intervals (CIs) were calculated from PROMIS scores using an anchor-based method. Using a bootstrapping technique with 1,000 iterations, the Youden index was calculated to determine the best specificity and sensitivity coordinates to maximize their combination. Finally, preoperative variables associated with the likelihood of achieving the PASS were assessed.

Results:

There was a strong association between PASS thresholds and PROMIS domains, especially Pain Interference (PASS threshold of <56.0, area under the receiver operating characteristic curve [AUC] = 0.940), Pain Intensity (<48.4, AUC = 0.936), and Physical Function (>44.7, AUC = 0.883). The likelihood of achieving the PASS was not affected by age, race, gender, American Society of Anesthesiologists (ASA) class, body mass index, or severity of ankle deformity. Patients with worse preoperative Physical Function and Global Mental Health scores were less likely to meet the PASS threshold for Physical Function postoperatively (p = 0.028 and 0.041).

Conclusions:

The ability to reach the PASS after TAR was most strongly associated with postoperative PROMIS pain scores. However, PASS thresholds were generally poorer than population means. This demonstrates that patients do not need to reach normal pain or physical function levels to have an acceptable symptom state after TAR.

Patients with Hip Osteoarthritis Have a Higher Rate of Spinal Reoperation Following Lumbar Spinal Fusion
Authors: Mills Emily S. , Wang Jennifer C. , Richardson Mary K. , Alluri Ram K. , Hah Raymond J. , Cleary Ekaterina , Lau Edmund , Ong Kevin , Heckmann Nathanael D.
Published: May 2024

Background:

Lumbar spinal pathology is known to affect outcomes following total hip arthroplasty (THA). However, the effect of hip osteoarthritis (OA) on outcomes following lumbar fusion has not been well studied. The purpose of this study was to determine the association between hip OA and spinal reoperation following lumbar spinal fusion.

Methods:

The 5% Medicare Part B claims database was queried for all patients who underwent primary elective lumbar fusion from 2005 to 2019. Patients were divided into 2 groups: those who underwent elective THA within 1 year after primary lumbar fusion, indicating that they had severe hip OA at the time of lumbar fusion, and those who underwent lumbar fusion with no diagnosed hip OA and no THA during the study period. Exclusion criteria included THA as a result of trauma, revision THA or primary THA in the 5-year period before primary lumbar fusion, <65 years of age, and no enrollment in the database for 5 years before and 1 year after primary lumbar fusion. The primary outcome was spinal reoperation within 1, 3, and 5 years. Multivariable Cox regression was performed with age, sex, diabetes, heart disease, obesity, smoking status, osteoporosis, number of levels fused, use of posterior instrumentation, use of an interbody device, use of bone graft, and surgical approach as covariates.

Results:

Overall, 1,123 patients (63.4% female; 91.3% White; mean age, 76.8 ± 4.1 years) were included in the hip OA group and 8,893 patients (56.2% female; 91.3% White; mean age, 74.8 ± 4.9 years) were included in the control group. After multivariable analysis, patients with severe hip OA had significantly greater rates of revision surgery at 3 years (odds ratio [OR], 1.61; p < 0.001) and 5 years (OR, 1.87; p < 0.001) after the index lumbar fusion.

Conclusions:

Patients with severe hip OA at the time of primary lumbar fusion had a significantly increased risk of spinal reoperation at 3 and 5 years postoperatively. These data provide further evidence to support performing THA prior to lumbar fusion in the unsettled debate regarding which surgery should be prioritized for patients with simultaneous degenerative diseases of the hip and lumbar spine.

Level of Evidence:

Prognostic Level III. See Instructions for Authors for a complete description of levels of evidence.
Acceptance and uptake of vaccines against tetanus, influenza, pertussis, and COVID-19 among pregnant and postpartum women in low- and middle-income countries: a systematic review and meta-analysis protocol.
Authors: Ayouni Imen , Amponsah-Dacosta Edina , Noll Susanne , Kagina Benjamin M. , Muloiwa Rudzani
Published: May 2024

Background
Pregnant women, foetuses, and neonates are particularly vulnerable to vaccine-preventable diseases (VPDs). These VPDs are associated with high morbidity and mortality among expectant mothers and their foetuses and neonates. Vaccination during pregnancy can protect the expectant mother from VPDs to which she may be especially vulnerable while pregnant. In addition, the passive transfer of maternal neutralizing immunoglobulin G (IgG) and secretory immunoglobulin A (IgA) also protects the foetus against congenital infections and may further protect the neonate from infection during the first few months of life. Despite this, coverage of recommended maternal vaccines remains suboptimal globally, especially in resource-constrained settings. Determinants of vaccine acceptance and uptake are frequently understudied in low and middle-income countries (LMICs) and among specific groups such as pregnant and postpartum women. This proposed systematic review will assess the acceptance and uptake of vaccines against tetanus, influenza, pertussis, and COVID-19 vaccines among pregnant and postpartum women in LMICs.

A Boolean search strategy employing common and medical subject heading (MeSH) terms for tetanus, influenza, pertussis, and COVID-19 vaccines, as well as vaccine acceptance, hesitancy, together with uptake, pregnancy and postpartum, will be used to search electronic databases for relevant literature published between 2009 and 2023. Only studies conducted in LMICs that investigated determinants of acceptance, hesitancy and uptake of tetanus, influenza, pertussis, and COVID-19 vaccines among pregnant and postpartum women will be eligible for inclusion in the review. The quality and the risk of bias of all eligible full-text articles will be assessed using the Joanna Briggs Institute's (JBI) critical appraisal tools.
Discussion
This protocol proposes a systematic review and meta-analysis that aims to assess the uptake of maternal vaccines and to systematically appraise and quantify determinants of the acceptance and uptake of recommended vaccines during pregnancy and postpartum in LMICs. A better understanding of these factors and how they influence maternal vaccine decision-making will enable public health practitioners as well as global and national policymakers to design more effective interventions as we look towards expanding the scope and reach of maternal immunization programs.

In South Korea, sites that are not under the algae alert system yet frequently experience algal blooms are managed as designated algal observation sites. Chlorophyll-a is one of the key water quality parameters monitored at these sites. To investigate trends in chlorophyll-a, this study used water quality monitoring data from two representative algal observation sites in the Yeongsan River basin from January 2016 to December 2002. Based on the data, an exploratory data analysis was conducted to examine the distributional characteristics of each variable, after which an appropriate probability distribution was inferred to explain fluctuations in chlorophyll-a. Building on these data, three statistical models and four artificial intelligence-based algorithms for predicting chlorophyll-a were developed, and their levels of predictive performance were quantitatively compared. The more precise methods proposed in this study for predicting chlorophyll-a levels are expected to significantly aid in water quality management at various monitoring sites.

Soil loss is one of the major environmental concerns with significant negative implications on top soil loss, land degradation, waterbody sedimentation and agricultural productivity. These losses arise from the complex interaction of climatic, biophysical, and anthropogenic factors. This study aimed at assessing and predicting soil loss using the Revised Morgan-Morgan Finney (RMMF) model and CA-Markov chain analysis in the Upper Tana basin. The datasets used included: rainfall intensity, mean daily rainfall, total annual rainfall, land use land cover, canopy height, soil moisture content, soil bulk density, canopy cover fraction, fraction of rainfall not intercepted by canopy, ground cover fraction, root depth, soil surface cohesion, soil detachability factor, evapotranspiration and the digital elevation model. The GIS-based RMMF model was used to simulate soil losses for the years 2002, 2012 and 2022 while the CA-Markov was used for predicting soil loss for the year 2030. The findings revealed that total soil loss exhibited a decreasing trend between 2002 and 2012 from 30159416.72 t/ha to 28762653.24 t/ha and later increased in 2022 which showcased the highest recorded level of 43527091.89 t/ha with a mean of 14.838±32.55 t/ha, 14.400±32.11 t/ha and 21.063±29.87 t/ha respectively. By 2030, the very low soil loss is expected to have a higher coverage of 60.14% followed by the low at 36.77%, the moderate at 0.31%, the high at 0.12% and the very high class at 2.67% of the total area. The study concluded that the anthropogenic, biophysical and climatic factors each play a key role in soil loss.

Published: May 2024

Introduction
This review aims to assess the effect of oral administration of probiotics and/or prebiotics in children and women of reproductive age (WRA) to improve intestinal iron absorption, hemoglobin, and ferritin levels.
Methods
Randomized controlled trials from published literature on probiotics and or prebiotics for prevention or treatment of anemia as a supplement or fortification in children or WRA till Jan 31, 2023, were included. Studies on probiotics and prebiotics in patients with anemia due to other causes were excluded. Screening and data extraction was done using Distiller SR and meta-analysis was performed using Revman 5.4.1.
Results
Total 1925 records were identified from Pubmed, Embase, and Cochrane, of which 29 were included in the systematic review (14 supplementation and 15 fortification studies; 15 studies in children and 14 studies in WRA). The major interventions included galacto-oligosaccharide, inulin, heat-killed H61, Lactobacillus plantarum 299v, Lactobacillus reuteri, Lactobacillus acidophilus.
Meta-analysis of 9 studies (3 in WRA and 6 in children) showed that the use of prebiotics and/or probiotics was associated with little or no effect on hemoglobin as compared to control [Very low certainty of evidence]. Use of prebiotic and/or probiotic led to a significant increase in ferritin levels in WRA (mean increase 2.39 ng/ml, 95% CI 0.48-4.29, p=0.01, n=133) vs control (n=129) but not in children [Low certainty of evidence]. Administration of a prebiotic and/or probiotic along with oral iron was not associated with increased hemoglobin or ferritin vs administration of iron only (2 studies in WRA and children each) [Low to moderate certainty of evidence]. Use of prebiotics and/or probiotics was associated with 1.39% and 6.92% increase in fractional iron absorption in WRA when given alone or along with iron. However, iron absorption was not found to be increased in children [Low certainty of evidence].
Conclusion
There is some evidence to show that the use of prebiotics or probiotics (especially Lp299v and GOS) can improve iron absorption in women and children and lead to improvement in ferritin levels in women. However, the current evidence does not conclusively show the benefit of these interventions in improving hemoglobin levels in women and children.

This study aims to clarify the longitudinal flexural cracking characteristics in hogging moment regions, and propose the practical calculation method of cracking load and ultimate bearing capacity for steel-GFRP strips-UHPC composite deck structure. The longitudinal flexural behavior of two steel-GFRP strips-UHPC composite beams in the hogging moment regions are conducted through a three-point loading test method. Their failure modes and mechanism, cracks propagation and distribution characteristics are analyzed considering the influence of reinforcement ratio. Variation law of mid-span displacement, maximum crack width, strains and interface slip with load are discussed. Calculation method of cracking load and ultimate bending capacity of steel-GFRP strips-UHPC composite beams are proposed. The results show that with the increase of reinforcement ratio, the cracking load, ultimate bending capacity and interface slip value corresponding to the ultimate load are improved effectively. However, the development of cracks is inhibited, the crack width, average crack spacing and strain of reinforcement bars are reduced as the reinforcement ratio increased. The strain distribution along the height of mid-span section satisfies the plane cross-section assumption. Theoretical cracking load and ultimate bearing capacity of composite beams considering the tensile contribution of UHPC achieve good agreement with the experimental values.

In order to evaluate the allelopathic interference of different varieties of alfalfa on notorious weeds, the sensitivity of green foxtail and barnyardgrass to the extracts from the first, second, and three stubbles of six varieties were investigated through plate culture. The germination rate, seedling length, seedling fresh weight, root length, and root fresh weight of weeds were measured in this study to comprehensively elucidate allelopathic effects. The results suggested that: (1) The allelopathy of six alfalfa varieties tested showed obvious interspecific differences, the inhibition of Zhongmu No.3 on weeds was weaker than other cultivars. (2) The inhibitory effect of alfalfa extracts on green foxtail was enhanced with the increase of stubble times, while the differences between three stubble times on barnyardgrass were not clear, especially between the first and second stubbles. (3) Compared with barnyardgrass, green foxtail was generally more susceptible to the extracts. (4) The inhibitory effect of alfalfa extract on root was stronger than seedlings in the same weeds. The study may help to comprehensively reveal the allelopathic effect of different alfalfa varieties in the first three stubbles on green foxtail and barnyardgrass, providing scientific evidence for weed control based on natural plant extracts in the future.

Published: May 2024

Background

Cellular signals orchestrating synapse formation and neuronal network function remain poorly understood. To explore the critical signaling pathways in neurons and their influence on network development, pharmacological assays were employed to inhibit multiple signaling pathways in cultured neurons.

Methods

Immunofluorescence and western blotting are applied to identify the expression of synapse-related proteins within neurons. micro-electrode arrays (MEAs) are employed to study the developmental characteristics of neuronal networks. RNA sequencing is utilized to determine the gene expression profiles pertaining to multiple signaling pathways.

Results

Canonical c-jun N-terminal kinases (JNK) pathway is necessary for pre- and post-synaptic specializations, while phosphatidylinositide3-kinases (PI3K) is a key to postsynaptic specialization and affects the puncta sizes of presynaptic marker. Unexpectedly, pharmacological inhibition of JNK pathway significantly suppressed the mean firing rate (MFR), network burst frequency (NBF) and regularity of network firing after 4 weeks, but did not alter the synchrony of the network. During network development, PI3K pathway regulates the longer burst duration and lower network synchrony. Gene sets associated with neurodevelopmental processes and myelination was disturbed during restraining these signal pathways. Furthermore, inhibition of the PI3K signaling pathway obviously transformed voltage-gated ion channel activity, synaptic transmission and synaptic plasticity of neurons.

Conclusion

This study reveals that JNK and PI3K signaling pathways play different roles during synapse formation, and these signaling pathways have a lasting impact on the development of neuronal networks. Thus, this study provides further insights into the intracellular signaling pathways associated with synapse formation in the development of neuronal networks.
