A Review of South African Consumer Awareness of Fast-Fashion and Sustainable Practices in the Textile and Clothing Industry
Authors: Mollel-Matodzi Nailejileji , Mastamet-Mason Anne
Published: December 2024

The global textile and clothing industry is one of the main contributors to socio-environmental harm through fast-fashion practices. Sustainable fashion practices by the textile and clothing industry and consumers can reduce socio-environmental harm. Over the past 12 years, academic research has steadily increased on South African consumers’ knowledge regarding fast fashion and sustainability in the textile and clothing industry. The objective of this paper is twofold: first, to synthesize South African consumers’ awareness of the socio-environmental impacts of fast-fashion practices, and second, to synthesize their awareness of sustainable fashion practices. This research employed narrative and systematic review methodologies to identify and analyze relevant data. Understanding consumers’ knowledge regarding fast and sustainable fashion can guide policymakers and stakeholders in the textile and clothing industry in developing targeted interventions to foster sustainable practices among consumers, thereby promoting sustainable consumption and production patterns. This review paper found partial awareness and misconception among consumers of the socio-environmental harm caused by fast-fashion practices. Furthermore, although consumers know of various sustainable fashion practices, their awareness level is limited. This study recommends that future research use diverse representative participants to capture a broader range of perspectives and provide a more comprehensive understanding of consumer knowledge. The study further recommends research that focuses on consumer misconceptions about fast-fashion and sustainable fashion practices among consumers. Collaboration between the government, the textile and clothing industry, higher education, and marketing agencies to create continuous interactive knowledge dissemination to consumers through various platforms is essential.

This study aimed to examine the lingual data of speech on Facebook posts, alleged to have resulted in defamation and to describe the case handling process by the police in Banyumas City, Central Java Province, Indonesia. The data was collected through documents handed over by the police. The data was analyzed qualitatively within the framework of forensic linguistic theory. The main findings of the study are that there were six linguistic aspects on the Facebook posts suspected to contain a defamation case under study, namely dialectology, forensic phonetics, forensic language style, language structure analysis, discourse analysis, and authorship. Additionally, the case handling process underwent seven steps, i.e. delivery of application letter from the police to head of linguists’ office, delivery of assignment letter to appointed linguists by head of linguists’ office, linguists’ documents examination by the police, data collection from the police, forensic linguistic data analysis, review session of analysis results, and submission of final results to the police. This study suggests that upholders of law and linguists should work hand in hand in the interest of justice and that linguists build their understanding of law issues within this multidisciplinary practice, while at the same time, upholders of law benefit from the experience of linguists as expert witness.
Green Finance Adoption Using Planned Behaviour Theory: The Case of Vietnam
Authors: Dang Quang N.
Published: December 2024

This paper examines the motivation of firms in Vietnam to access green finance as opposed to traditional finance. It aims to identify the intentions behind accessing green finance and develop a model of factors influencing these intentions. The research addresses the limited participation of smaller economies like Vietnam in the global green finance market, despite an increasing demand for sustainable development. A successful green transformation requires substantial capital, and a well-structured financial market is crucial for this effort. Therefore, this study seeks to understand what drives firms in developing economies to adopt green finance. The research is based on a survey of 50 Vietnamese firms across various industries. Using pre-structured questions, it applies the Planned Behavior Theory (PBT) to create a model explaining the intention to adopt green finance. Factor analysis and logistic regression are employed to identify the main factors influencing these intentions. Results show that a positive attitude toward green finance, due to benefits like enhanced reputation and reduced financing costs, significantly affects firms' intentions to adopt green finance. Internal stakeholders, such as employees and shareholders, are key motivators, while external pressures may serve as obstacles. Interestingly, the availability of finance sources and stakeholder support did not emerge as significant predictors. The study suggests that policymakers should develop supportive regulations and that firms should engage internal stakeholders and increase awareness of green finance's benefits to promote its broader adoption in emerging economies like Vietnam.
Antyrosyjskie działania grupy Anonymous jako element kultury hakerskiej w kontekście agresji Rosji na Ukrainę
Authors: Myślak Dominika Agata , Plewik Kinga
Published: December 2024

Celem artykułu jest przybliżenie kultury hakerskiej i zobrazowanie antywojennych, a także antyputinowskich działań grupy Anonymous. Działania te pojawiły się po napaści Rosji na Ukrainę 24 lutego 2022 roku. Szybko przybrały na intensywności, równolegle do eskalacji wojennego barbarzyństwa, którego źródło było i wciąż pozostaje na Kremlu. Autorki starają się pokazać, że niekorzystny wizerunek cyberprzestępców, do jakich zalicza się zazwyczaj także grupę Anonymous, załamuje się, gdy bierze się pod uwagę fakt, iż ich aktywność w Sieci miała również pozytywny wymiar etyczny. W początkowym okresie ukraińsko-rosyjskiego konfliktu zbrojnego członkowie tej międzynarodowej społeczności postawili sobie za zadanie przeprowadzenie akcji uświadamiających obywateli Federacji Rosyjskiej o rzeczywistych pobudkach wywołania wojny przez Władimira Putina w Ukrainie i o jej przerażających skutkach. Materiał źródłowy i zarazem analityczny stanowiły informacje zamieszczone na specjalistycznym portalu „Komputer Świat”.

Autor przybliża jedyny tomik poetycki Jadwigi Żenczykowskiej Wiersze, który ukazał się w 2002 roku. Został wydany pośmiertnie w Szczytnie, w mieście, do którego Kresowiaczka trafiła w 1945 roku po kilkunastu latach tułaczki wywołanej przewrotem bolszewickim (1917) i utratą wielkiego majątku ziemskiego w Aleksandrówce pod Kijowem. Ta nauczycielka języka polskiego i rosyjskiego w polskich szkołach powszechnych, podstawowych oraz średnich pozostawiła po sobie niezwykłe liryczne wspomnienia, mające bardzo często konkretnych adresatów z najbliższego i dalszego jej otoczenia. W tym sensie Wiersze Jadwigi Żenczykowskiej posiadają nie tylko oryginalne walory literackie i są dalekie od amatorskiego wierszoklectwa, ale odznaczają się ponadto sporą wartością realioznawczą, zwłaszcza powojenną, i związaną z egzystencją w nowej dla niej małej ojczyźnie – w mazurskim Szczytnie. Wiersze są intymną podróżą autorki od dziecięctwa po lata dojrzałe, zatopioną w śpiewnych wersach i tanecznych rytmach, w których wyczuwa się wołyńskie aromaty, smutek i zarazem radość z powodu przymusowego przesiedlenia.

Authors: Owen Rhiannon K , van Oppen James D , Lyons Jane , Akbari Ashley , Davies Gareth , Torabi Fatemeh , Abrams Keith R , Lyons Ronan A
Published: December 2024

Background

The COVID-19 pandemic resulted in increased mortality directly and indirectly associated with COVID-19.

Aim

To assess the impact of the COVID-19 pandemic on all-cause and disease-specific mortality and explore potential health inequalities associated with area-level deprivation in Wales.

Methods

Two population-based cohort studies were derived from multi-sourced, linked demographic, administrative and electronic health record data from 2016 to 2019 (n = 3,113,319) and 2020 to 2022 (n = 3,571,471). Data were analysed using generalised linear models adjusting for age, sex, area-level deprivation and time at risk.

Results

COVID-19 deaths peaked in January 2021 (54.9/100,000 person-months, 95% confidence interval (CI): 52.4–57.5). The pandemic indirectly affected deaths, with higher than expected maximum relative mortality rates (RR) related to cancer (RR: 1.24, 95% CI: 1.13–1.36), infectious diseases (excluding respiratory infections) (RR: 2.09, 95% CI: 1.27– 3.43), circulatory system (RR: 1.41, 95% CI: 1.28–1.56), trauma (RR: 2.04, 95% CI: 1.57– 2.65), digestive system (RR: 1.54, 95% CI: 1.25–1.91), nervous system (RR: 1.63; 95% CI: 1.34–2.00) and mental and behavioural disorders (RR: 1.85, 95% CI: 1.58–2.16). Mortality associated with respiratory diseases (unrelated to COVID-19) were lower than expected (minimum RR: 0.52, 95% CI: 0.45–0.60). All-cause mortality was lower in least deprived communities compared with most deprived (RR: 0.61, 95% CI: 0.60–0.62), and the magnitude of this effect increased during the pandemic.

Conclusions

All-cause and disease-specific mortality directly and indirectly associated with COVID-19 increased during the COVID-19 pandemic. Socioeconomic disparities were exacerbated during this time.

Published: December 2024

TikTok Shop is a trending buying and selling platform because it is highly favoured by consumers, in its journey TikTok Shop is suspected of predatory pricing. This research aims to discuss the impact of predatory pricing (TikTok Shop), how Islamic economics views the practice of predatory pricing, and the role of the government in predatory pricing. This research uses descriptive qualitative methods and library research. The impact of TikTok Shop's predatory pricing is to reduce competition. TikTok Shop gains a dominant position, this creates unfair competition that can damage local businesses that have survived for years. Islam regulates muamalah activities, which must pay attention to the following: Prohibition of monopoly and price manipulation, Islamic economic principles encourage healthy and fair competition in the market. Islam teaches that fair competition encourages innovation, product quality, and better choices for customers. Islam encourages fair and healthy competition in the market as a means to improve the quality of products and services. Unfair price forecasting that exploits market weaknesses or disadvantages small competitors may be considered a violation of social justice principles. The government is taking a firm stance on TikTok Shop, which is suspected of violating MOT PMSE by offering products at very low prices, both from big brands and imported products, which can defeat local MSMEs in market competition

Authors: Teplickaya L. , Goncharov M. , Semenova E. , Chernyakov D. , Shatunova S. , Kalaeva E.
Published: December 2024

The work investigated the optimization of nutrient media and in vitro cultivation conditions of the lichen E. prunastri. A study of the growth and development of the culture under controlled conditions revealed a number of patterns at the morphometric and biochemical level. To select optimal conditions for in vitro cultivation of natural isolates, it was adopted to use various variants of the Murashige-Skoog nutrient medium with the addition of alcohol extracts or aqueous decoctions of bark from plants on which the lichen grows naturally (oak, apple, sloe, pear). The growth parameters of E. prunastri isolates have been established. The influence of cultivation conditions on the development of lichen in vitro and the production of biologically active pharmacologically valuable substances was studied. The viability and level of biomass accumulation of E. prunastri isolates from various natural habitats on Hoagland’s medium varied significantly (3–13 times), which indicates the need to select a highly active producer. The size of lichen cells when grown in vitro in a liquid nutrient medium is higher than in natural conditions (by 20.0–38.5 %%). It has been shown that the best medium for the accumulation of biomass and biologically active compounds (lichen acids, chlorophyll) is the Murashige-Skoog variant with the addition of apple bark decoction when grown in diffused light
(1000–1500 lux) with a 16-hour photoperiod, temperature 18+1oC and humidity 90+5 %. The chemical analysis of the raw materials of cultivated and wild-growing lichen, as well as the resinoid (thick extract) based on it, indicates a similar qualitative and quantitative composition, which indicates the prospects of the biotechnology for their production. A comparative assessment of natural isolates of E. prunastri and determination of the possibilities of their cultivation in vitro in connection with the development of innovative lichen technology significantly expands the understanding of the biotechnological aspects of obtaining the “oak moss” resinoid (thick Evernia extract) for use in the perfumery, cosmetics, food and pharmaceutical industries as an odor fixer, aromatic and pigment flavoring agent, a source of biologically active pharmacologically effective compounds.

Authors: Yuferev V. , Pogodina S.
Published: December 2024

Aim. The analysis of physiological features and reserves of cardiovascular system of professional sportswomen of pre-involutive (37–45 years) and reproductive (16–26 years) age ranges.
Materials and methods. We examined highly qualified sportswomen who do not take oral contraceptives, with an average duration of the menstrual cycle 28–30 days (representatives of long distances in running and swimming) pre-involutive (37–45 years, n=18) and reproductive (16–26 years, n=32) periods. Carried out ELISA analysis of the content of gonadotropic and sex hormones, in vitro immunochromatographic test for ovulation, the analysis of heart rate variability, analysis of reogram Central hemodynamics, Bicycle test speed-increasing load, the statistical analysis of the data.
Results. Physiologically justified functional ability of the cardiovascular system of women of the pre-involutive period to adapt to strenuous physical activity in professional sports. In the pre-revolutionary period of sportswomen relative decrease in activity of the central and autonomous mechanisms of regulation of a heart rhythm, formation of the most favorable period of autonomous regulation from 20 to 22 days that can be considered as a regulatory reserve is established. At the same time, the reserves of cardiac and vascular links in achieving a high functional level of the cardiovascular system are relatively reduced, and the tension is more pronounced in the vascular link.
Conclusion. In professional sportswomen 37–45 years in the second half of the anovulatory menstrual cycle, physiological features of the manifestation of reserve and compensatory effects at the level of regulatory, cardiac and hemodynamic links of the cardiovascular system were determined, which must be taken into account in dosing high-intensity loads. In professional athletes aged 37–45 years, a relative decrease in the activity of the central and autonomous mechanisms of heart rate regulation and the formation of the most favorable period of autonomous regulation of the cardiovascular system from day 20 to 22 from the beginning of the AMC was established, which allows this period to be considered potential for the manifestation of regulatory reserves at such an advanced age. Regulatory shifts in athletes aged 37–45 years in the periods of AMC are similar in quality to shifts in cardio-hemodynamics. At the same time, the reserves of the cardiac and vascular links in achieving a high functional level of cardiovascular system are relatively reduced, and stress is more pronounced in the vascular link, which must be taken into account when dosing high-intensity physical exertion. The effects of stress on the functions of the CCC in athletes aged 37–45 years are reflected at the level of systemic organization, which is manifested by the relatively high rigidity of systemic relationships. The main indicator correlating with IN during the AMC is the VLF component reflecting.
SYNTHESIS OF SELENIUM NANOPARTICLES STABILIZED WITH POLYVINYLPYRROLIDONE
Authors: Panov D.
Published: December 2024

In recent years, there has been an increase in publications devoted to the creation of new materials based on self-organized nanostructured composites of specified sizes and maintaining their stability for a long time. Nanosystems based on nanoselenium are of particular interest, as it is vital for humans and animals. However, in many regions of Russia, selenium deficiency is observed in agricultural soils. The least toxic and bioavailable is nanoscale selenium. Currently, the most widely used methods of chemical reduction of selenium ions in solutions using ascorbic acid, glucose, dithiourea and sulfur-containing amino acids. And high-molecular compounds are used as stabilizers, both natural (alginate, chitosan, arabinogalactan) and synthetic (polyethylene glycol, polyvinyl alcohol, polyvinylpyrrolidone). The aim of this work was the synthesis of self-organized selenium nanoparticles in a polyvinylpyrrolidone (PVP) matrix with different molecular weights. To establish the effect of the ratio of selenium–PVP components on the formation process, spectral and structural-morphological characteristics of selenium nanocomposites, as well as on their aggregative resistance to the environment.
Selenium nanoparticles were obtained by chemical reduction of sodium selenite with L-cysteine, in the presence of PVP grade «Kollidon® 30» (K-30) and grade «Kollidon® 90 F» (K-90). The viscometric method was used to determine the medium-viscosity molecular weights of two PVP samples (grades K-30 and K-90). The control of the aggregate stability of the obtained selenium nanoparticles was carried out by spectrophotometric and potentiometric methods.
As a result of this work, new bioactive systems based on selenium nanoparticles and a nonionic polymer – polyvinylpyrrolidone with different molecular weights were synthesized. The formation of selenium nanoparticles in the zero-valence state in aqueous solutions of PVP, which are sufficiently stable for 4–5 weeks, has been established by UV spectroscopy. It was found that the concentration and molecular weight of PVP do not significantly affect the structure and size of selenium nanoparticles, but affect the aggregate stability and «lifetime» of nanosystems.

Studi kalayakan bisnis berfungsi untuk menganalisis apakah bisnis yang akan kita bangun layak atau tidak, dan aspek utama yang harus terpikirkan selain aspek-aspek lainnya ketika akan memulai bisnis adalah perihal aspek hukum. Penyuluhan hukum ini bertujuan untuk mengedukasi masyarakat terkait aspek hukum dalam bisnis. Perlu diketahui, aspek hukum terkait izin usaha tidak hanya berlaku untuk bisnis yang besar saja, tetapi pemerintah mewajibkan semua jenis bisnis untuk memiliki izin usaha tidak kerkecuali bisnis UMKM juga wajib memiliki IUMK (Izin Usaha Mikro Kecil), hal ini dipertegas oleh gerakan pemerintah dengan menetapkan Peraturan Presiden Nomor 98 tahun 2014 Tentang Perizinan Untuk Usaha Mikro Dan Kecil yang bertujuan untuk memberikan kepastian hukum dan sarana pemberdayaan bagi Pelaku Usaha Mikro dan Kecil (PUMK) dalam mengembangkan usahanya. Kegiatan penyuluhan ini dilaksanakan karena sebagian besar pelaku UMKM di Distrik Hubikiak belum sepenuhnya mengenal dengan baik regulasi bisnis yang diatur dalam perundang-undangan. Hal ini dapat menghambat perkembangan bisnis UMKM dan bahkan memunculkan potensi pelanggaran hukum. Penyuluhan ini merupakan bentuk pengamalan Tri Dharma Perguruan Tinggi sekaligus dukungan terhadap pekerjaan layak dan pertumbuhan ekonomi. Pemahaman legalitas ini sangat penting bagi pelaku UMKM. Diharapkan hal ini juga dapat memberikan kepercayaan kepada pelanggan, mitra bisnis, dan investor bahwa bisnis pelaku UMKM tersebut dijalankan dengan integritas dan sesuai dengan standar yang ditetapkan. Lebih lanjut, legalitas usaha dan izin edar dapat melindungi hak-hak bisnis, pemilik, dan konsumen.

Published: December 2024

El moldeo por inyección es un proceso en el que se producen dispositivos plásticos. Sin embargo, al fabricar estos productos se pueden observar defectos tales como: disparos cortos, marcas de flujo, de hundimiento, de quemaduras, rebabas, líneas de soldadura, deformaciones o pieza incompleta, etc. Para evitar estos defectos se deben considerar todos los parámetros y cantidades físicas asociadas al proceso, así como la fenomenología llevada a cabo como: la generación del polímero fundido, flujo y transporte del mismo hasta la conformación del producto que toma lugar en la cavidad del molde. En este trabajo se obtuvieron vasos de polipropileno (PP) utilizando un molde de colada fría en una máquina de inyección Krauss-Maffei (KM) modelo CX 80-380. Los parámetros de inyección se ajustaron de acuerdo a la posibilidad de lograr altos índices de reproducibilidad con la menor cantidad de defectos, haciendo cálculos en parámetros fundamentales como fuerza de cierre, temperatura, así como el tiempo total en la inyección.

En este estudio, se elaboraron películas poliméricas de alcohol polivinílico (PVA) con complejo mononuclear de europio. Para la preparación del complejo mononuclear se empleó óxido de europio, se usaron dos rutas de síntesis preparando cloruro y nitrato de europio. Posteriormente, las disoluciones de estos precursores se combinaron con benzoato de sodio para formar los complejos. Estas rutas permitieron elucidar diferencias en la intensidad luminiscente de los polvos de compuestos mononucleares y las películas poliméricas de PVA. Mediante la espectroscopía FT-IR se identificaron los grupos funcionales y la interacción entre el ion metálico y los ligandos, confirmando la formación de complejos. Las micrografías SEM revelaron diferencias significativas en la morfología de los polvos obtenidos, siendo las partículas sintetizadas a partir del nitrato más homogéneas que las obtenidas con el cloruro. El análisis de difracción de rayos X mostró un ordenamiento estructural en los complejos, confirmando la cristalinidad. Por último, los estudios de luminiscencia revelaron una mayor intensidad luminiscente en los complejos sintetizados por la ruta del nitrato, destacando las transiciones características del ion Eu³⁺, con una mejor dispersión y emisión en los recubrimientos de PVA comparados con los polvos.

Published: December 2024

This research used a mixed-methods descriptive survey approach, where we examined the responses of 47 children in Grade 3 to numbers and operations problems. In this study, we jointly addressed one objective: (1) determining children's challenges in solving addition/subtraction and number-related problems. The problems included 14 items, each comprising 1 to 7 tasks and required participants to answer in one-on-one interview form to identify their problem-solving difficulties. In this study, we qualitatively classified and provided descriptions for the problems encountered accordingly, and we quantitatively analysed the correct and incorrect responses using only descriptive statistics. One of the key findings that stood out was that almost 50% of the children faced difficulties in comprehending and applying number concepts and skills. They exhibited challenges, such as limited knowledge in recalling basic addition/subtraction facts and expressing numbers in multiple ways. While children were observed to have the potential to address problems, they encountered greater obstacles when performing additions and subtractions. Nevertheless, their struggles with numerical problems indicated an underlying incapacity to solve arithmetic operations accurately. The implication is that most children at the start of Grade 3 did not understand number concepts and strategies for solving addition and subtraction problems and required guidance to perform the tasks.

Modern contraceptives, such as implants, coils, injections, and pills, are methods that interfere with normal ovulation and fertilization processes to prevent conception. These contraceptives play a crucial role in reproductive health and positively impact women's well-being. However, there is global concern about their underutilization. It is against this background that this study sought to investigate the utilization of modern contraceptives among women of reproductive age in Turkana County. The specific objective of this study was to find out how health care system affects the access and utilization of modern contraceptives among women in Turkana Central Sub-County. The systematic sampling method was employed to select study participants, and quantitative data was collected through questionnaires. The Statistical Package for Social Sciences (SPSS) version 20.0 was used to analyze descriptive data and produce frequency tables, graphs, and pie charts. Chi-Square tests with a 95% confidence interval and a 0.05 margin of error were used to establish correlations between research variables. The findings of this study indicate that the healthcare system, such as accessibility to healthcare facilities, the availability of family planning services, healthcare workers' attitudes, and service hours, were crucial in determining the use of contraceptives.
UNSTEADY SURFACE PRESSURE CHARACTERIZATION OF THE BASE PRESSURE REGION OF A HEAVY GOODS VEHICLE
Authors: Gatto Alvin
Published: December 2024

This paper presents an experimental investigation into the time-dependent aerodynamics within the base region of a representative heavy goods vehicle. The work conduced is surface-based, and involved using multiple, customized dynamic pressure sensors for both aligned and mis-aligned flow configurations. Uniquely, the methodology adopted allowed high resolution, detailed interrogation of this region and the presentation of several new insights. Among the most significant are the detailed characterization and quantification of the degree of flow-misalignment necessary to prompt development of a complex vortex/wake structure reported previously. Once developed, this structure dominated the upper-windward quadrant of the base region with measured unsteady surface loads up to 2-3 times greater than that observed under nominal flow conditions. Presented spectral information also showed evidence of both Strouhal-based vortex shedding within the wider base-pressure region as well as more localized regions containing higher spectral contributions centered broadly at several multiples of the primary shedding frequency.

Published: December 2024

Agrobiodiversity is critical to agroecosystem health, and a key source of agrobiodiversity is farmers’ varieties. Reintegration of these resources into agroecosystems requires improving their knowledge base, including the creation of crop models. One underutilized farmers’ variety is Loka Pere, a local banana (Musa spp.) found in Adolang and Adolang Dhua villages, Majene Regency, West Sulawesi. The purpose of this study was to create a simple growth model simulating Loka Pere’s growth response to soil macronutrient concentrations across three traditional growth environments. Soil samples were collected and analyzed for Ntot, Corg, C:N, pH, Pav, Kexc, Naexc, Caexc, Mgexc, and CEC. Plants were measured for pseudostem circumference at the plant base and 1 meter height, plant height, and hands per bunch at three growth phases. Principal component analysis was used to define a productivity index. Multiple linear regression models and non-linear generalized additive models were fit utilizing soil parameters as input variables and growth parameters individually as response variables. Growth models varied in goodness of fit (R2 = 0.11 to 0.69). The most important soil variables for Loka Pere growth were Ntot, Caexc, and CEC, and the most important soil variables for yield were pH, CEC, and Pav. The growth responses of Loka Pere to the availability of certain nutrients differed from responses found in studies on other varieties.

Drought stress is one of the biggest challenges in rice production, requiring effective fertilization strategies to improve plant resilience. This study evaluated the effect of ammonium sulfate ((NH₄)₂SO₄) and Chromolaena odorata (Cho) fertilization on early growth and physiological responses of rice (Oryza sativa L. cv. Inpago 11) under field capacity (100% WFC) and drought stress (50% WFC) conditions. Experiments were conducted using a divided plot design with three fertilizer treatments control, (NH₄)₂SO₄, and (NH₄)₂SO₄ + Cho) and two levels of water availability. Results showed that at 100% WFC, (NH₄)₂SO₄ + Cho fertilization significantly increased maximum growth potential (48.09%), vigour index (29.77%), and growth speed (16.60%.etmal-1 ) compared to the control. Total chlorophyll and carotenoid contents also increased by 50% and 63.8% in the (NH₄)₂SO₄ + Cho treatment compared to the control. At 50% WFC, differences between treatments became insignificant for most parameters, but proline accumulation increased by 62.5% in the (NH₄)₂SO₄ + Cho treatment compared to the control. This study shows that the combination of (NH₄)₂SO₄ + Cho effectively improves early growth and physiological resilience of rice under optimal conditions, but its effectiveness is reduced under drought stress, emphasizing the importance of adaptive fertilization strategies to water availability.

Published: December 2024

Osmanlı İmparatorluğu’nun son döneminden itibaren İstanbul’da ilkokul düzeyinde okullaşmada hızlı bir artış gerçekleşmiştir. Özellikle Cumhuriyet ile beraber gerçekleştirilen reformlar çerçevesinde Cumhuriyetin ilk yıllarından itibaren yeni eğitim sistemine uygun okullar inşa edilmeye başlamıştır. Bu okulların çoğu Maarif Vekaleti tarafından hazırlanan “tip projelere” göre yapılmıştır. Ülkenin birçok şehrinde inşa edilmeye başlanan bu yapılar, son dönem Osmanlı ve erken Cumhuriyet Dönemi mimarlığında etkin olan Birinci Ulusal Mimarlık üslubunda (1908-1930) tasarlanmıştır. Bu yapılardan biri de eski Beyazıt İlkokulu’dur. 1923 yılında inşa edilen yapı Erken Cumhuriyet Dönemi ilkokullarına bir örnektir. Bu makalede; günümüzde İstanbul Üniversitesi Mimarlık Fakültesi Dekanlık binası olarak kullanılan eski Beyazıt İlkokulu’nun tarihi ve mimari özellikleri incelenecektir. Birinci Ulusal Mimarlık Dönemi tip proje okullarından biri olan yapının cephe özellikleri ve planı bakımından değerlendirilmesi amaçlanmaktadır. “İlk Mektep”, “Beyazıt Zükür İptidai’si (Erkek İlkokul’u)” ve “5. İlk Mektep” gibi isimlerle de anılan yapı inşa edildiği dönemin mimari üslubunu koruyarak özgün eğitim işlevini devam ettirmekte olup İstanbul’da Eski Saray (Saray-ı Atik) alanındaki Birinci Ulusal Mimarlık Dönemi eğitim yapılarının ilk örneklerinden olması nedeniyle önemlidir.
