İndirim Marketlerinde Kadın İstihdamı: Aile Bakkalından Satış Temsilcisine
Authors: Kayaalp Özcan Pelin , Yüce Yasemin
Published: July 2024

İndirim marketlerinin çok hızlı bir şekilde her sokak başında açılması ve kadınların bu marketlerde çalışan olarak görünür olması, bu alanın çalışma ilişkileri bağlamında, özellikle kadınlar için nasıl gözüktüğünü düşündürmektedir. İndirim marketlerine kadın çalışanların gözüyle bakmayı hedefleyen bu çalışma, hizmet sektörü içerisindeki kadın çalışma hayatını marketlerdeki boyutuyla tartışmaya açmaktadır. Buradan hareketle araştırmada, indirim marketi çalışanı kadınlarla yapılan derinlemesine görüşmeler ışığında, kadınların burada ne tür çalışma koşullarını deneyimledikleri ve bir kadın olarak market çalışanı olmanın ne anlama geldiği sorularına cevap aranmıştır. Farklı indirim marketlerinde en az 6 aydır çalışan 15 kadınla yapılan görüşmeler sonucunda, dev kurumsal firmaların kayıtlı çalışanları olarak kadınların “esnek” çalışma örüntülerine benzeyen bir anlayış ve çalışma biçimi gösterdikleri tespit edilmiştir. Yapılan işin tanımsızlığı (herkes her işi her an yapar), çalışma saatleri konusundaki esneklik (iş bitmeden paydos yapılmaz) ve değişken çalışma ortamı (her mağazanın kendine özgü bir işleyişi var) markette çalışmayı betimlemektedir. Özellikle kadın çalışanlardan güleryüz ve müşteri ilişkilerinde başarı beklenmektedir. Bu durum kadının duygusal emeğini market işinde en önemli kazanma aracına dönüştürmektedir. Dahası, aile içi geleneksel ilişki biçimlerinin ve rollerinin markete aktarımı neden marketlerde kadın sayısının arttığını açıklamakta ve aynı zamanda zincir marketlerin kadınların toplumsal cinsiyete dayalı rollerinden nasıl yararlandıklarını göstermektedir.
Memlûk Sultanı Eşref Halil b. Kalavun’un Rumkale’yi Fethi (1292)
Authors: Gökhan İlyas
Published: July 2024

Bu makalede Memlûk Sultanı Eşref Halil’in 1292’de Rumkale’yi fethi konu edinilmiştir. Rumkale, Güneydoğu Anadolu Bölgesinde Fırat’ın batısında, Gaziantep’in Nizip ve Yavuzeli ilçeleri arasında olup, günümüzde turistik ve ören yeridir. İlkçağ’da kurulduğu bilinen Rumkale Bizans İmparatorluğu’nun Güneydoğu Anadolu’da en önemli kalelerinden biriydi. Stratejik ve coğrafi konumu ile öne çıkan Rumkale, Malazgirt Savaşı sonrası Ermenilerin eline geçmiştir. Daha sonra Urfa Haçlı kontluğuna bağlanan kale 1148’de yeniden Ermenilerin eline geçmiş ve onların Katolikosluk merkezi olmuştur. Anadolu’da yaşayan Ermenilerin önemli bir kısmı burada bulunan Ermeni ruhani liderine bağlanmışlardır. Rumkale’ye Süryaniler de yerleşmiş olup burada bir patrikleri vardı. Moğolların Anadolu’yu işgali sürecinde Rumkale Ermenileri Moğollara tabi olmuşlardır. Burada yaşayan Ermeniler Moğollarla ittifak yaparak Birecik ve Halep gibi Memlûk kentlerine saldırılar yapmışlardır. Bu yüzden Memlûkler Rumkale’yi ele geçirmişlerdir. Bu çalışmada Memlûk dönemin ana kaynakları ve araştırma eserlerinden faydalanılarak Rumkale’nin fethi detaylı şekilde incelenmiştir. Ayrıca kalenin stratejik konumu ve fiziki durumu güncel eserlerden istifade edilerek de ortaya konmuştur.

Authors: Alkaç Erkan
Published: July 2024

The Cappadocia Güray Museum is a private institution housing a diverse array of archaeological artifacts spanning different historical periods. Among the museum's inventory are three amphora stamps, all originating from the island of Rhodes. Eponyms and fabricant names have been identified on these stamps. The names of Ἀρχοκράτης II and Ἀρχοκράτης have been determined in the eponym stamps. It is stated that Ἀρχοκράτης II served c. 185 BC and Ἀλεξίμαχος c. 150 – c. 147 BC in the eponym. The fabricant’s stamp also belongs to Ὄλυμπος I. The stamps on amphorae with both handles preserved are important for determining the activity period of this fabricant. The years of service of the eponyms associated with Ὄλυμπος I indicate that the fabricant produced amphorae between c. 185 – c. 174/172 BC. In the stamp where the name of Ἀρχοκράτης II is determined as the eponym, the month name Δάλιος and the rose symbol are seen. In the stamp where the name of the eponym Ἀλεξίμαχος is identified, there is Πάναμος as the month name. There is a burning torch on the stamp, where the fabricant’s name is Ὄλυμπος I.
Anlama İki Farklı Yaklaşım: Frege’de Anlamın Nesnelliği ve Dummett’ta Anlamın Kamusallığı Üzerine
Authors: Türkmen Birlik Pınar
Published: July 2024

Dil felsefesinin temel sorusu, dilsel anlamın doğası sorunudur. Bu bakımdan dil felsefelerinin, bir anlam teorisiyle taçlandırılmaları son derece değerlidir. Anlam teorilerinin temel olarak ortaya koymayı amaçladıkları şey, belli bir dil içindeki ifadelerin anlamlarının sistematik bir şekilde tanımlanmasıdır. Çalışmamız da anlam konusuna yönelteceği ilgi kapsamında, yirminci yüzyıl dil felsefesi üzerinde önemli etkilere sahip olan Frege ile onun önemli ölçüde etkilediği düşünürlerden ve kendisinin, belki de en önemli yorumcularından biri olan Dummett’ın ortaya koyduğu anlam teorilerinin örtüşen yönlerinden çok birbirlerinden ayrıldıkları bir yönü mercek altına alacaktır. Birbirlerinden ayrılan ve çalışmamıza konu olan bu yön elbette ki Frege’nin ortaya koyduğu anlam teorisinde anlama yüklenen “nesnel” karakter ve Dummett’ın anlamın kullanım olduğu yönündeki görüşünü yansıtan anlamın “kamusallığı” düşünceleridir. Çalışmamız boyunca, bu iki düşünürün, anlamın nesnelliği ve kamusallığına dair düşünceleri üzerinde yoğunlaşırken, ayrıca Dummett’ın ortaya koyacağı anlam teorisinin hangi yönlerden Fregeci bir karakter sergilediğini ve onun doğruluk koşullu teorileri hangi hususlarda eksik bularak bu teorinin ayrıca kamusallık gereksinimlerini karşılaması gereken bir teori de olması gerektiğini düşünmüş olmasının nedenlerini de art alanda görmeye çalışacağız.

Authors: Karadağ Murat
Published: July 2024

Bu çalışma, Türkiye’de modernleşme ve ulusal kimlik inşası sürecinde tiyatronun nasıl bir dönüşüm geçirdiğini ve erken Cumhuriyet döneminde egemen ideolojinin tiyatro alanına nasıl yansıdığını ele almaktadır. Tanzimat döneminden itibaren Batı’dan getirilen fikirler ve teknolojilerle birlikte bir toplumsal dönüşüm süreci başlamıştır ve tiyatro bu dönüşüm sürecinin bir parçası olmuştur. Cumhuriyetin kuruluşu ise bir kültür devrimine sahne olmuş, çağdaşlaşma ve millileşme eksenli kültür politikası bağlamında tiyatro, Batı kültürüne entegre olmanın ve ulusal bilinci güçlendirmenin bir aracı olarak kullanılmıştır. Çalışmanın amacı, söz konusu süreçte tiyatronun ideolojik işlevini hem kültür politikası çerçevesindeki uygulamalar hem de dönem içerisinde yazılan ve sahneye konan piyeslerin konuları üzerinden anlamaktır. Bu amaçla konuya ilişkin literatür üzerinden hem tiyatronun erken Cumhuriyet dönemindeki kurumsallaşma sürecinin ideolojik boyutları hem de dönemin piyeslerinde egemen siyasal ideolojinin nasıl yansıma bulduğu değerlendirilmiştir. Çalışma, tiyatro alanındaki dönüşümlerde Cumhuriyetin altı ilkesinin (cumhuriyetçilik, milliyetçilik, halkçılık, devletçilik, laiklik, inkılapçılık) ideolojik bir çerçeve oluşturduğunu ve alanın biçimlenmesinde önemli bir role sahip olduğunu ortaya koymaktadır
Ultraprecision photonic thermometry with nonadiabatically modulated coupled resonances
Authors: Weng Wenle , Luiten Andre N.
Published: July 2024

Sensing minute temperature fluctuations is of key importance to many cutting-edge industrial and scientific applications. While recent developments in microphotonic thermometers have achieved unmatched sensitivity, the wide adoption of these sensors is hindered by their limited dynamic range as well as the complex design. Here, we present a coupled-resonance-based scheme that utilizes a single-laser-driven optical microresonator to enable self-referenced thermometry with unprecedented simplicity. The thermometry complexity is further reduced by applying nonadiabatic modulation to the coupled resonances, which not only eliminates the need for external modulation but also yields a record-setting few-nanokelvin resolution. To highlight the applicability and the versatility of the developed thermometers, state-of-the-art microresonator applications including laser frequency stabilization and robust nonlinear frequency conversion are demonstrated over a wide range of operating temperatures. Being compatible with existing photonic integrated circuit building blocks, this easy-to-use, high-performance thermometry approach may be implemented extensively in compact optical and photonic systems.

Community-wide distribution of azithromycin, otherwise known as mass drug administration (MDA), is a component of the World Health Organization-endorsed SAFE strategy for the elimination of trachoma as a public health problem. In the Republic of South Sudan, 2.9 million people are known to live in areas that are known to require interventions and warrant MDA. This study estimated the total costs and cost per person treated during MDA in two counties, Kapoeta North and Kapoeta East, in South Sudan. MDA was conducted in Kapoeta North and Kapoeta East counties from October 2020 to January 2021. Following training and community sensitization, a core team, consisting of a height measurer, a drug dispenser, and a data recorder, delivered the intervention. A detailed costing database was developed in Microsoft Excel. An ingredients approach was used to capture all financial and economic costs incurred from a payer perspective. Primary outcomes included the total cost of MDA in each county and the cost per person treated in each county. In Kapoeta North, 58,226 people were treated at a financial cost of $71,350 USD. This corresponds to a unit cost of $1.22 per person treated. The total economic cost of the intervention was $99,036, at a unit cost of $1.70 per person treated. In Kapoeta East, 156,092 people were treated at a total financial cost of $168,404. This corresponds to a unit cost of $1.08 per person treated. The total economic cost of the intervention was $243,205, at a unit cost of $1.56 per person treated. The study highlights the cost variation for MDA implementation across two counties of South Sudan. As the South Sudan trachoma program expands, this information will be valuable for program planning.
Assessment of tuberculosis transmission probability in three Thai prisons based on five dynamic models

Published: July 2024

This study aimed to assess and compare the probability of tuberculosis (TB) transmission based on five dynamic models: the Wells–Riley equation, two Rudnick & Milton-proposed models based on air changes per hour (ACH) and liters per second per person (L/s/p), the model proposed by Issarow et al, and the Applied Susceptible-Exposed-Infected-Recovered (SEIR) TB transmission model. This study also aimed to determine the impact of model parameters on such probabilities in three Thai prisons. A cross-sectional study was conducted using data from 985 prison cells. The TB transmission probability for each cell was calculated using parameters relevant to the specific model formula, and the magnitude of the model agreement was examined by Spearman’s rank correlation and Bland–Altman plot. Subsequently, a multiple linear regression analysis was conducted to investigate the influence of each model parameter on the estimated probability. Results revealed that the median (Quartiles 1 and 3) of TB transmission probability among these cells was 0.052 (0.017, 0.180). Compared with the pioneered Wells–Riley’s model, the remaining models projected discrepant TB transmission probability from less to more commensurate to the degree of model modification from the pioneered model as follows: Rudnick & Milton (ACH), Issarow et al., and Rudnick & Milton (L/s/p), and the applied SEIR models. The ventilation rate and number of infectious TB patients in each cell or zone had the greatest impact on the estimated TB transmission probability in most models. Additionally, the number of inmates in each cell, the area per person in square meters, and the inmate turnover rate were identified as high-impact parameters in the applied SEIR model. All stakeholders must urgently address these influential parameters to reduce TB transmission in prisons. Moreover, further studies are required to determine their relative validity in accurately predicting TB incidence in prison settings.
“Community strengthening through citizen monitoring of water quality: A systematic review”
Authors: Dominguez-Rendón Edith , Villada-Canela Mariana , Muñoz-Pizza Dalia Marcela
Published: July 2024

Citizen participation in decision-making is a fundamental democratic pillar of democracy. However, the degree of citizen involvement and recognition by governmental institutions may be conditioned by the level of competence and knowledge demonstrated. Therefore, carrying out collective projects can contribute to strengthening citizen engagement in water management issues. Nonetheless, there is limited knowledge about the various types of citizen engagement and the practices that have facilitated greater inclusion in decision-making regarding water resources. This study aims to identify and analyze practices that strengthen water community organizations through citizen monitoring-based involvement. A systematic literature review was conducted using the PRISMA method. The research was guided by the following questions: What are the differences in the level of citizen involvement and the degree of transformation facilitated by citizen monitoring of water quality (CMWQ) between the global North and South? What practices strengthen community organizations in decision-making based on CMWQ? Moreover, what challenges do community water organization structures community water organization structures face when based on CMWQ? A total of 161 publications were identified for the analysis of critical themes. After applying the eligibility criteria, 33 documents were selected for content analysis. The reviewed monitoring exercises indicate that the highest level of citizen organization achieved by participants is commonly recognized as “Water Committees”. One practice that strengthens these committees is the generation of collaboration agreements among different types of allies, based on a shared objective. However, in the Global South and at the institutional level, there is still resistance to water quality data generated by citizen monitors, especially in regions with large-scale open-pit mining projects. To sustain the efforts of community figures, monitoring programs with public funding need to be established, and public policies supporting these initiatives at the institutional level must be implemented.
Identifying facilitators and barriers to the uptake of medication for opioid use disorder in Washington, DC: A community-engaged concept mapping approach

Published: July 2024

Introduction

Opioid overdose is a major public health challenge. We aimed to understand facilitators and barriers to engagement in medication for opioid use disorder (MOUD) among persons with OUD in Washington, DC.

Methods

We used a cross-sectional mixed-methods concept mapping approach to explore MOUD engagement between 2021–2022. Community members at-large generated 70 unique statements in response to the focus prompt: “What makes medication for opioid use disorder like buprenorphine (also known as Suboxone or Subutex) difficult to start or keep using?” Persons with OUD (n = 23) and service providers (n = 34) sorted and rated these statements by theme and importance. Data were analyzed with multidimensional scaling and hierarchical cluster analysis, producing thematic cluster maps. Results were validated by our community advisory board.

Results

Seven themes emerged in response to the focus prompt: availability and accessibility; hopelessness and fear; unmet basic needs; characteristics of treatment programs; understanding and awareness of treatment; personal motivations, attitudes, and beliefs; and easier to use drugs. “Availability and accessibility,” “hopelessness and fear,” and “basic needs not being met” were the top three identified barriers to MOUD among consumers and providers; however, the order of these priorities differed between consumers and providers. There was a notable lack of communication and programming to address misconceptions about MOUD’s efficacy, side effects, and cost. Stigma underscored many of the statements, showcasing its continued presence in clinical and social spaces.

Conclusions

This study distinguishes itself from other research on MOUD delivery and barriers by centering on community members and their lived experiences. Findings emphasize the need to expand access to treatment, dismantle stigma associated with substance use and MOUD, and address underlying circumstances that contribute to the profound sense of hopelessness and fear among persons with OUD–all of which will require collective action from consumers, providers, and the public.
Cross-linguistic syntactic priming as rational expectation for syntactic repetition in the bilingual environment
Authors: Xu Kexin , Zeng Tao
Published: July 2024

Recent research suggests that syntactic priming in language comprehension—the facilitated processing of repeated syntactic structures—arises from the expectation for syntactic repetition due to rational adaptation to the linguistic environment. To further evaluate the generalizability of this expectation adaptation account in cross-linguistic syntactic priming and explore the influence of second language (L2) proficiency, we conducted a self-paced reading study with Chinese L2 learners of English by utilizing the sentential complement-direct object (SC-DO) ambiguity. The results showed that participants exposed to clusters of SC structures subsequently processed repetitions of this structure more rapidly (i.e., larger priming effects) than those exposed to the same number of SC structures but spaced in time, despite the prime and target being in two different languages (Chinese and English). Furthermore, this difference in priming strength was more pronounced for participants with higher L2 (English) proficiency. These findings demonstrate that cross-linguistic syntactic priming is consistent with the expectation for syntactic repetition that rationally adapts to syntactic clustering properties in surrounding bilingual environments, and such adaptation is enhanced as L2 proficiency increases. Taken together, our study extends the expectation adaptation account to cross-linguistic syntactic priming and integrates the role of L2 proficiency, which can shed new light on the mechanisms underlying syntactic priming, bilingual shared syntactic representations and expectation-based sentence processing.
Massive stocking of chum salmon (Oncorhynchus keta) fry fattens non-native brown trout (Salmo trutta) in Hokkaido, Japan

Published: July 2024

In Japan, stocked chum salmon (Oncorhynchus keta) fry may have become the perfect prey for non-native brown trout (Salmo trutta), which are popular targets of anglers. If this is the case, fry stocking which is intended to boost commercial fishing may be helping to sustain the populations of an invasive predator. We used dietary and biochemical analyses to examine whether brown trout quickly restore their nutritional status following wintertime declines by preying upon chum salmon fry that are stocked in spring. We targeted six rivers in Hokkaido, Japan, three with fry stocking and three without. Changes in brown trout condition factor, triglyceride contents in muscle and serum, serum insulin-like growth factor-1 (IGF-1; an indicator of short-term growth), and docosahexaenoic acid (DHA; an essential fatty acid abundant in fish) content in muscle were examined between before stocking and during the stocking period in the six rivers. Dietary analysis showed that brown trout preyed on fry during the stocking period in all stocked rivers. Their nutritional status tended to be higher during the stocking period than before stocking in stocked rivers, but not in unstocked rivers. These results suggest that the massive stocking of chum salmon fry provides brown trout with the perfect prey to quickly restore their nutritional status and fuel increased growth; this may therefore be a controversial issue among stakeholders.
Battle Royale, brands and the experiential video game economy
Authors: Burroughs Benjamin , Slaney Malcolm
Published: July 2024

This article explores how the Battle Royale (BR) format in video games positions game users within unique articulations of play, where fully formed narratives in each game conjoin players and brands within the BR format. This game mechanic has allowed game developers to tell customized and interactive stories while also enabling companies to forge branded experiences within these games. Fortnite, Apex Legends and Call of Duty: Warzone are three of the most popular BR titles analysed through an autoethnographic approach in this work. These games have developed story worlds and unique characteristics within their playable maps where players forge affective ties through gameplay and develop a sense of ownership. Understanding how and why BR games create these experiences is vital to an emergent experiential gaming economy manifesting in branded, experiential digital spaces. BR games curate branded experiences for their players, whether through gameplay or in-game events, cultivating a gaming format that has influenced the emergence of a branded experiential mode of gameplay.

Authors: Torrieri Rocio , Elgart Jorge Federico , Gagliardino Juan José
Published: July 2024

Introducción. En personas con alto riesgo de desarrollar diabetes, la ingesta de alimentos y calorías tiene influencia en su calidad de vida y sobre la posible evolución a diabetes. Por ello, el objetivo fue describir y estimar el consumo de energía y nutrientes, y su adecuación a los requerimientos nutricionales, en personas con Prediabetes (PreD).
Metodología. Estudio observacional descriptivo transversal sobre un grupo de personas adultas de La Plata con PreD a las que se les midió la ingesta de calorías y nutrientes por día, a partir del registro alimentario NutriQuid. Se realizó su análisis descriptivo y verificó indicadores de ingesta alimentaria, para luego comparar su adecuación a las recomendaciones nutricionales.
Resultados. Se evaluaron 115 personas con PreD, de las cuales el 69,3% presentaba obesidad. La mediana de ingesta calórica fue de 2.046,3 kcal/día, valor superior a la recomendada, con una distribución de 40,4% carbohidratos, 19,3% proteínas y 38,3% de grasas. Asimismo, sólo el 18,3% de los participantes presentó un consumo adecuado de fibra, el 29,6% un consumo adecuado de grasas saturadas y el 42,6% un consumo adecuado de colesterol.
Conclusión. Nuestro estudio muestra que las personas con PreD presentan un consumo alto de calorías, grasas totales, grasas saturadas y colesterol en comparación a las recomendaciones, lo cual determina un consumo desbalanceado de macronutrientes, y bajo en fibra. Esto podría predisponer al desarrollo diabetes tipo 2, síndrome metabólico, y aumentar el riesgo cardiovascular.

Published: July 2024

Biofertilizers symbolize a promising and eco-friendly approach to increasing agricultural productivity while reducing the hazardous environmental impact of chemical fertilizers. Biofertilizers are compounds containing living microorganisms or their byproducts that, when applied to soil, enhance nutrient uptake and promote plant growth. These biological agents include nitrogen-fixing bacteria, mycorrhizal fungi, and phosphate-solubilizing microorganisms. Biofertilizers are well recognized for their composition, cost-effectiveness, and environment-friendly nature. These are safe substitutes for hazardous synthetic fertilizers. They contribute to soil health and biodiversity conservation by enriching the soil with beneficial microorganisms. This review provides an overview of biofertilizers, their significance in modern agriculture, and their potential to promote sustainable farming practices.

Authors: Haider Abdul Ali Al-Shawi Noor , Ebrahiminejad Zhaleh , Asgary Somayeh
Published: July 2024

In this research, a three-component composite was synthesized by using carbon nanotube as the background phase. Iron oxide phase with high magnetization and low coercivity (with particle size of 200 nm) has been coated on the carbon nanotubes. Then, the silver nanoparticles were coated on a conductive and magnetized substrate by an ultrasonic method. Semiconductor photocatalys is a favorable route for the degradation of organic pollutants. Ultraviolet–visible spectrophotometry has been used to investigate the photocatalytic properties of synthesized nanocomposite and control of their dye degradation on methyl blue, methyl orange and methyl red. The obtained nanocomposite is easily collected due to its magnetic property and does not pose a risk to environmental waters. The dye degradation degree has been compared for the produced nanocomposite. The experimental results confirmed that methyl red shows the greatest amount of degradation within 1 h, which was about 90 %, methyl orange shows about 80 %, and methyl blue shows the lowest degradation, around 60 %.

Published: July 2024

Objectives

Pseudohypoparathyroidism (PHP) comprises a cluster of heterogeneous diseases characterized by hypocalcemia and hyperphosphatemia due to parathyroid hormone (PTH) resistance. PHP type 1B (PHP1B) is caused by heterozygous maternal deletions within GNAS or STX16. STX16 exon 2–6 deletion is commonly observed in autosomal dominant (AD)-PHP1B, while sporadic PHP1B commonly results from methylation abnormalities of maternal differentially methylated regions and remains unclear at the molecular level.

Case presentation

A 39-year-old male patient with PHP1B, who had his first seizure at 15 years of age, presented to our hospital. The methylation-specific multiplex ligation-dependent probe amplification results showed a half-reduced copy number of STX16 exon 5–7 and loss of methylation at GNAS exon A/B. His mother also had a half-reduced copy number of STX16 exon 5–7 but with normal methylation of GNAS. His father has a normal copy number of STX16 and normal methylation of GNAS.

Conclusions

For the recognition and early diagnosis of this kind of disease, here we report the clinical symptoms, auxiliary examinations, genetic testing characteristics, and treatment of the patient.

Published: July 2024

Objectives

Fetal cleft lip is a common congenital defect. Considering the delicacy and difficulty of observing fetal lips, we have utilized deep learning technology to develop a new model aimed at quickly and accurately assessing the development of fetal lips during prenatal examinations. This model can detect ultrasound images of the fetal lips and classify them, aiming to provide a more objective prediction for the development of fetal lips.

Methods

This study included 632 pregnant women in their mid-pregnancy stage, who underwent ultrasound examinations of the fetal lips, collecting both normal and abnormal fetal lip ultrasound images. To improve the accuracy of the detection and classification of fetal lips, we proposed and validated the Yolov5-ECA model.

Results

The experimental results show that, compared with the currently popular 10 models, our model achieved the best results in the detection and classification of fetal lips. In terms of the detection of fetal lips, the mean average precision (mAP) at 0.5 and mAP at 0.5:0.95 were 0.920 and 0.630, respectively. In the classification of fetal lip ultrasound images, the accuracy reached 0.925.

Conclusions

The deep learning algorithm has accuracy consistent with manual evaluation in the detection and classification process of fetal lips. This automated recognition technology can provide a powerful tool for inexperienced young doctors, helping them to accurately conduct examinations and diagnoses of fetal lips.

Data suggests an increasing trend in the detection of autism spectrum disorder (ASD) in our country and abroad. Families raising children with this multifaceted, lifelong disorder face significant challenges in communication breakdown and maintaining social relationships, which make it difficult for ASD individuals and their families to successfully function and thrive in society. This article presents mothers’ experiences and sources of stress. A qualitative research approach was adopted to show the subjects’ experiences. Data was collected using focus groups, with open-ended, non-restrictive responses to questions according to the researcher’s intended areas of assessment. The results show a number of generalised semantic spaces related to the child’s own appearance and behaviour, fear of the future and the internalisation of negative attitudes, as well as to the challenges of social services and infrastructure and mothers’ professional activities.

Published: July 2024

Laboratory and pilot scale pretreatment processes were assessed for empty fruit bunch (EFB) at different morphologies using anhydrous ammonia pretreatment (AAP). The AAP was used to deconstruct the complex structure of EFB through physical and chemical reaction to promote efficient conversion of the carbohydrates to monomeric sugars. Different morphologies of EFB samples used were unpressed EFB (UE), pressed EFB (PE), pressed and shredded EFB (PES), and lastly pressed, shredded and ground EFB (PESG). The APP process was optimized using a 1.0 L laboratory scale reactor and further scaled up to a 22 L pressure vessel (AAPB). AAP-PESG contained 76.2%, and AAP-PES contained 75.5% of structural carbohydrates, showing no significant difference. AAP-UE showed the lowest glucan conversion of 28%. The optimal laboratory conditions adopted were 135 °C, 30 min, moist to dry EFB loading of 2:1, and ammonia to dry EFB loading of 1:1. Glucan conversion of AAP-PES were 87%, 80%, and 62% at 1%, 3%, and 6% glucan loadings, respectively. The AAP-PES detected acetamide concentration at 7.3 mg/g, while AAPB-PES was only at 4.4 mg/g. Chemical composition, Fourier transform infrared spectroscopy, Brunauer Emmett Teller surface area, and scanning electron microscopy supported the assessment of AAP and AAPB processes.

Psoriasis is a common chronic, immune-mediated, systemic inflammatory disease, with a special predilection for the skin and joints. Approximately one third of patients with psoriasis will have associated psoriatic arthritis and it usually begins with the skin lesions, evolving to articular manifestations. Since psoriatic arthritis could present with permanent articular damage with chronic pain and disability, it is important to seek for early diagnosis. We will talk about our recent experience with rheumatological ultrasound, studying a small and selected group of patients, along with an important literature review.
Analysis of quality indicators for brake pads made of cast iron and multicomponent composite materials
Authors: Sirenko К.A. , Mazur V.L.
Published: July 2024

The properties and performance characteristics of railway brake pads made of cast iron and a multicomponent composite material (rubber-asbestos and asbestos-free rubber mixtures) are considered. Approaches to assessing the force, friction coefficient, and thermal conductivity of brake pads made of different materials in the contact zone with the wheels of railway rolling stock are analysed. The quality indicators of brake pads of different types made of cast iron, composite rubber compound, and composite material with cast iron inserts are compared. It is shown that the coefficients of friction of cast iron pads on the wheel surface are 1.5...2.0 times lower than the coefficients of friction of pads made of composite rubber compound. The main disadvantage of brake pads made of composite rubber compound is the low thermal conductivity of this friction material and, as a result, insufficient heat removal from the contact area between the pad and the wheel of the vehicle. The above fully applies to composite pads with cast iron inserts, which do not help the unsatisfactory situation with heat removal from the friction zone between the pad and the wheels. The dependences of the thermal conductivity coefficient of cast iron with lamellar graphite on its hardness, degree of eutecticity, and carbon equivalent of its chemical composition are considered. It is emphasised that the technical specifications for brake pads made of composite material do not comply with the legislation of Ukraine, since they do not regulate the percentage of rubber compound components and their chemical composition. The standards for cast iron brake pads fully meet the legal requirements for their construction. Foundries in Ukraine have modern equipment and are prepared to manufacture cast iron pads of improved quality, in particular by making them from alloyed and partially graphitised cast iron.

Published: July 2024

У науковому дослідженні описано простий і легкодоступний синтез нанокристалів сульфіду купрума-стібія. Зразки були синтезовані сольвотермічним методом з використанням ряду речовин (мідь, сурма та елементарна сірка). В експериментах використовували антимонілтартрат калію як джерело сурми, а розчин сульфату етилендіаміну – як вихідна речовина сульфіду. Синтез наночастинок Cu3SbS4 здійснювали шляхом регулювання мольного співвідношення сірки до міді та контролю об'ємних співвідношень розчинника і органічного середовища (етиленгліколь + поліетиленгліколь). Процес проводили за температур 383–393 К протягом 12 годин і синтезували наночастинки тіостибіату купруму з виходом 85 %. Властивості отриманих наночастинок досліджували методами фізико-хімічного аналізу – ТГА, РФА, ТЕМ, EDS.
La evaluación del Aprendizaje Basado en Juegos en contextos informales mediante ciencia de datos
Authors: Rubio-Campillo Xavier , Marín-Rubio Kevin , Corral-Vázquez Celia
Published: July 2024

The emergence of digital Game-Based Learning (GBL) has sparked interest in assessing its efficacy. This assessment needs to consider the complex mix of narrative and interactivity typical of video games, which makes it difficult to evaluate to what extent a video game achieves its stated learning objectives. This challenge is exponentially increased when gaming sessions happen spontaneously in informal contexts, without any supervision by educators or the option to assess the players’ prior knowledge and skills. This work presents a methodology for analyzing GBL experiences based on data science and the data collection functionalities offered by current game development platforms. This strategy is applied to the analysis of a social media simulator designed to promote information literacy within the video game Julia: A Science Journey. The system collected data on 436 sessions from 112 unique players over six months. The records included information on replayability, identification of fake news, and reaction times. The results suggest that players become more adept and swifter at identifying fake news through repeated games. Success in identifying misinformation is also related to the topic, with hoaxes related to scientific content being more easily recognized than those associated with political controversies.

Impacto familiar del diagnóstico de muerte inminente
Authors: Díaz Victoria , Ruiz Mario , Flórez Carla , Urrea Yenny , Córdoba Verónica , Arbeláez Cristian , Rodríguez David
Published: July 2024

El presente artículo analiza cómo ante la aparición de una enfermedad oncológica en fase avanzada, la historia familiar y las lógicas de la relación favorecen u obstaculizan el manejo de la información sobre la enfermedad, la expresión de las emociones y el acompañamiento al enfermo. La información de las familias fue recolectada a través de entrevistas semiestructuradas a nueve grupos familiares y a cinco enfermos; e interpretada mediante análisis de contenido. Los resultados sugieren que familias con una comunicación veraz del diagnóstico y el pronóstico constituyen vínculos de soporte mutuo y mayor flexibilidad en los roles. Contrariamente, familias con dificultades en la comunicación presentan problemáticas en la interacción entre sus integrantes y en el acompañamiento del enfermo.

Dilemas bioéticos asociados a la farmacodependencia en etapa crónica
Authors: Ávila Navarrete Viviana Carmenza
Published: July 2024

El presente artículo ofrece un análisis acerca de algunos dilemas bioéticos que se presentan al realizar abordajes e intervenciones en relación a la farmacodependencia crónica, los cuales se originan en la comprensión de lo humano al no asumir la visión del hombre como una unidad integrada. Se parte de los principios de la ética personalista y del reconocimiento sobre los emergentes patrones derivados del placer inscritos en el uso de sustancias psicoactivas y el impacto como enfermedad, pasando por el acercamiento a un Otro como persona-humana y una mirada prudente sobre el terapeuta, culminando con un llamado a la formación profesional e interdisciplinar para forjar modificaciones en la manera de pensar e instaurar aportes profundos acerca de la vida misma.

Authors: Andrade Rodríguez Luis Gerardo , Landero Hernández René
Published: July 2024

El conflicto trabajo-familia ha sido estudiado desde las últimas décadas al reconocerse el impacto negativo que tiene el trabajo sobre la familia y viceversa. Dicho conflicto se considera un riesgo psicosocial que perjudica tanto a trabajadores como a organizaciones. Los trabajadores afectados presentan síntomas de malestar físico y psicológico como fatiga, ansiedad, depresión y estrés. Por su parte, las organizaciones se ven afectadas por consecuencias como el absentismo, el bajo rendimiento y la deserción de los empleados. La investigación reconoce la necesidad de la búsqueda de conciliación entre la vida laboral y familiar. Asimismo, el conflicto trabajo-familia forma parte de la teoría de ajuste, la cual estudia los motivos de conflicto y conciliación entre el trabajo y la familia.
