ISOLASI DAN KARAKTERISASI JAMUR SELULOLITIK DARI TANAH PERKEBUNAN TEBU DESA GUNUNG WARAS KABUPATEN WAY KANAN
Authors: Rony Setiawan  , Sumardi
Published: August 2024

Sugarcane production is increasing, but waste in sugarcane plantations is also increasing, in the form of unwanted leaves and residual sugarcane stalks, which have a high cellulose content. To handle this organic waste, biodegradation agents in the form of cellulolytic fungi can be used, so it is necessary to screen cellulolytic fungi that can thrive and adapt to the sugarcane plantation environment. Organic particles, or litter, become a place of life for microorganisms such as fungi, bacteria, and other organisms. The purpose of this study was to identify the types of cellulolytic fungi found in sugarcane plantation soil in Gunung Waras Village, Way Kanan Regency, examine the effect of temperature and pH fluctuations on these fungi, and test their pathogenicity to plants. This study produced two fungal isolates that have the ability to degrade cellulose, namely Cunninghamella sp. and Trichoderma sp., with cellulolytic indexes of 0.754 and 0.403, respectively. Both isolates were tolerant of several pH variations, and there were no significant differences at the 95% confidence interval in the mean mycelial biomass at pH 3, 5, and 7. They could grow well at 25°C but not at 45°C

Purple sweet potatoes (Ipomoea batatas) have captured the attention of nutritionists and food enthusiasts alike for their rich anthocyanin content, contributing to their vibrant hue and potential health benefits. However, purple sweet potato is not as popular as the orange and white varieties because of the high anthocyanin content, which may cause the purple sweet potato to taste less sweet than the other varieties. The purple sweet potato, known as Lembayung, has a high anthocyanin content (3.19-7.05 mg/100g) and tastes less sweet than other commercial varieties. Enhancing its’ sweetness will make it even more acceptable to the consumer while being a healthy starch substitute. Biofertilizer is a low cost and renewable source of plant nutrients that supplements chemical fertiliser. They have a symbiosis relationship with plant roots, where they break down nutrients in the soil for easy absorption and change of sugar from plant roots. This study was carried out to determine the effects of biofertiliser with chemical fertiliser application on quality (sweetness) and yield of Lembayung planted in mineral soil. The experiment was laid out in a Randomized Complete Block Design (RCBD) with three replications. The treatment involving combination of biofertiliser with chemical fertiliser and application of processed chicken dung as a basal fertiliser resulted in the highest sweetness with total sugar and SSC (Soluble solid content) of sweet potatoes. Studies conducted in MARDI reveal that biofertiliser application on the 2nd and 4th week after planting combined with chemical fertiliser application on the 3rd, 5th and 8th week after planting can improve the sweetness and yield of Lembayung sweet potatoes planted in mineral soil. This was demonstrated by increased total sugar in Lembayung tubers by up to 123.8% compared to sweet potato plants fertilised only with chemical fertilisers.

Cekaman Logam Berat Cromium Terhadap Tanaman
Authors: Suharjo Muhammad Hendrawan , Ernawati Rika , . Nurkhamim
Published: August 2024

Logam berat adalah unsur logam dengan berat/ massa atom tinggi. Dalam kajian lingkungan logam dikategorikan menjadi logam berat jika memilki berat jenis lebih besar dari 5 g/ml. Secara umum logam berat sudah bersifat racun pada konsentrasi yang rendah bagi tumbuhan, hewan dan manusia.  Logam berat dapat bersumber pada aktivitas alam (geogenic) dan aktivitas manusia (anthropogenic). Secara alami magma gunung api mengandung logam berat, demikian juga berbagai batuan juga mengandung logam berat. Sumber logam berat yang berasal dari aktivitas manusia antara lain gas buangan kenderaan bermotor, pertambangan, industri elektronika dan kimia, pestisida, pupuk dan lain-lain. Fakta yang ada menunjukkan bahwa masuknya logam berat ke tanah/ lingkungan terutama akibat aktivitas manusia. Masuknya logam berat ke lingkungan tidak serta merta meracuni makhluk hidup akan tetapi logam berat baru meracuni jika masuk ke dalam sistem metabolisme makhluk hidup dan melampaui ambang batas. Ambang batas untuk setiap jenis logam berat dan makhluk hidup berbeda.  Mekanisme tanaman dalam mengahdapi logam berat dapat dilakukan dengan berbagai cara tergantung jenis tanaman yaitu melalui  fitoekstrasi dan fitokelatin. Fitoekstraksi adalah salah satu bentuk fitoremediasi dimana tanaman melalui akar tanaman menyerap pencemar (logam berat) dari larutan tanah dan diakumulasi di batang dan daun (bagian tanaman yang dapat dipanen). Fitoekstraksi biasa digunakan untuk memulihkan tanah tercemar khususnya logam berat seperti Pb. Tanaman yang memiliki kemampuan untuk menyerap logam berat dalam jumlah yang lebih banyak disebut tanaman hyperaccumulator (hiperakumulator). Tanaman hiperakumulator adalah tanaman yang mampu mengakumulasi logam berat pada jaringan tanam dan bagian yang dapat dipanen yang berada diatas tanah pada kisaran 0,1 – 1% dari berat keringnya.

The Lecture Building of the Faculty of Engineering, Mulawaran University is located on Jalan Sambaliung and is a newly operating lecture building, this building provides parking space for two-wheeled and four-wheeled vehicles. Judging from the condition of the two-wheeled parking area, it looks uncomfortable because there are several entry and exit lanes that are quite narrow, so if the atmosphere is busy and there are two vehicles that meet from two opposite directions, they have to yield to each other. The method applied in this study is to use quantitative and qualitative methods by conducting a site survey to determine conditions in the field and distributing Likert-scale questionnaires to determine the user's comfort level.The results of the analysis obtained by the measurements in the parking area are many that are not in accordance with the Decree of the Director General of Land Transportation No. 272 ​​of 1996 concerning Technical Guidelines for the Implementation of Parking Facilities, there are only a few points that comply with the standards. Convenience in the parking area is somewhat uncomfortable even though the parking area capacity is sufficient and the parking area distance to the campus building is close, but some students stated that they had difficulty getting out, driving and placing their vehicles, the size of the circulation path was narrow, the security in the parking area was not good and there is no CCTV. The parking area is clean but at certain times it smells bad, there is lighting in the form of garden lights even though the lights are not bright and there are signs or markings even though some of the markings have faded.

Background: Infectious diseases continue to wreak havoc around the world causing directly or indirectly 17 million deaths per year. The present study was carried out to evaluate the in vitro antibacterial activity of the methanol extracts from the root of Sarcocephalus latifolius and from the leaves of Acacia siberiana, and their ability to potentiate the action of antibiotics against multidrug-resistant (MDR) Staphylococcus aureus. Methods: The antibacterial assays were performed using the broth microdilution method, and the extracts were screened for phytochemicals using standard qualitative methods. The effect of Sarcocephalus latifolius root extract on the functioning of H+/ATPases proton pumps of ATCC25923 Staphylococcus aureus was determined using a standard qualitative method. Results: The extracts of Sarcocephalus latifolius and Acacia siberiana had minimum inhibitory concentrations (MIC) ranging from 16 to 1024 µg/mL and 32 to 1024 µg/mL, respectively, with action spectra of 93.75% and 87.5% against the 16 strains of Staphylococcus aureus tested. The S. latifolius root extract contained alkaloids, phenols, and terpenoids as the main classes of secondary metabolites. In contrast, the A. siberiana leaf extract contained phenols and terpenoids as the major classes of secondary metabolites. The S. latifolius extract enhanced the activity of penicillin against 100% of the isolates tested. On the other hand, the A. siberiana extract enhanced the activity of Cefixime against 85.71% of the isolates tested with a 128-fold increase in activity. Conclusion: The results obtained in this study provide significant data that could potentially support the use of Sarcocephalus latifolius and Acacia siberiana in combating bacterial infections caused by multidrug-resistant Gram-positive Staphylococcus aureus.
Influence of temperature on the residual shear strength of landslide soil: role of the clay fraction
Authors: Dhakal Om , Loche Marco , Dahal Ranjan , Scaringi Gianvito
Published: August 2024

The shear strength is a fundamental parameter of soil that controls the occurrence and propagation of landslides. In pure clays, it depends on temperature according to the mineralogy, stress history, and hydro-mechanical boundary conditions. Landslide soils, however, are typically very heterogeneous and have a variable content of fines. The sensitivity of the residual shear strength of low-plasticity soil to temperature, in particular, is poorly understood, leaving significant uncertainties on the potential role of thermal forcing in landslides. We conducted ring-shear experiments on remoulded low-plasticity soil samples from the Melamchi catchment in central Nepal, where a large disaster occurred in 2021, with fifteen simultaneous landslides along the river corridor and a destructive flood. We performed the experiments in water-saturated conditions under representative normal stress values (50-100-150 kPa) and a constant rate of shearing (0.1 mm/min). During each test, we controlled the temperature and performed a heating-cooling cycle (20-50-20◦33 C) with the shearing ongoing. To evaluate the role of the clay fraction (grain size <0.002 mm), we obtained specimens from the same soil samples by retaining the finest portion under three different cutoff grain sizes (0.125, 0.063, and 0.020 mm). The collected data were analysed statistically, using variance and skewness to evaluate the goodness of interpretation. A t-test was also implemented to exclude data close to the experimental uncertainty, delineating the experiment’s significance at a 68% confidence interval (1σ). Our results revealed a decreased residual shear strength upon heating (thermal weakening), with the magnitude of this weakening correlating with the specimen’s clay fraction and normal stress. Notably, a response to heating only emerged in specimens with a clay fraction of at least 10% and higher clay fraction and normal stress were conducive to greater weakening. Yet, the observed effect was relatively small, corresponding to a decrease in friction angle of just ∼1◦. This suggests a minor role of temperature in the response of sheared low-plasticity soil; however, more experiments are needed, covering the wide range of mineral compositions of clayey soils, to understand the role of temperature in the shearing process and formulate robust empirical laws to quantify thermal effects.
The Neural Mechanisms of Race Priming in American Politics
Authors: Gonzalez Frank , Haas Ingrid Johnsen
Published: August 2024

What are the psychological mechanisms of racial “dog whistles” in American politics? Literature on race priming in American politics argues when race is primed implicitly, racial biases influence political evaluations, but when race is made salient, individuals can use controlled processing to inhibit automatic biases and abide by egalitarian norms. However, the neural mechanisms underlying these processes have yet to be examined directly. In a 2x2 within-groups experiment using functional Magnetic Resonance Imaging (fMRI), we examine these neural mechanisms. We find brain areas associated with conflict detection, evaluative processing, and controlled processing are more active when race is primed explicitly rather than implicitly, as expected, although we do not find substantial brain activation associated with automatic responses to be more active during implicit than explicit primes. Results are discussed in terms of understanding how racial cues influence political evaluations while considering America’s everchanging racial norms.
Attention Capture by Action Effects are Driven by Prediction Error Minimization
Authors: Kumar Neeraj , Sunny Meera
Published: August 2024

Previously, we showed that stimuli that are considered as action-effects are processed with priority (Kumar, Manjaly & Sunny, 2015). We considered the role of common-coding mechanisms in driving this effect. However, recent studies suggest that these effects may follow the principles laid out by the predictive coding framework. In the present study, we explore how predictions about various parameters involved in action-effect monitoring (location, SOA, contingency) modulate attention capture by an action effect. In five experiments we investigate the effects of uncertainty associated with these characteristics in driving attention capture. Specifically, a reliable prediction error driven by controlled irregularity seems critical for automatic processing of action effects. Moreover, in case of high regularity or high irregularity the visual system uses minimal information from the environment and hence attention control appears to be top-down. The findings present robust evidence supporting the role of predictive coding mechanisms in driving automatic processing of visual information.
Risk and protective factors for burnout among parents of children with complex care needs: Parents’ perspectives
Authors: Patty Nathalie , van Meeteren Karen , Minke  , Ketelaar Marjolijn , Schuengel Carlo , Willemen Agnes M.
Published: August 2024

Background: Parental burnout has been proposed as resulting from a persistent imbalance between stress-enhancing factors (demands/ risk factors) and stress-alleviating factors (resources/ protective factors). Parents of children with complex care needs (CCN) face this imbalance more often than parents in general. To address this, we need to know which factors are considered as risk and protective for burnout from the perspectives of parents of children with CCN. To facilitate targeted interventions, this study sought to explore both risk and protective factors associated with burnout as perceived by parents of children with CCN.Methods: We conducted semi-structured interviews with 38 parents, who recognized or identified themselves with burnout-related thoughts and feelings. Parents were selected for maximal variation, based on parental, child, and family characteristics. The data was analyzed through inductive thematic analysis.Results: Fifteen themes, divided in three categories were identified: 1) ‘the parent’ encompassing factors intrinsic to the parent, such as emotional factors and internal drivers, and physical health; 2) ‘the environment interacting with the parent’ including organization of care, social support, and socio-economic factors; and 3) ‘the sum of all factors’ – themes underscoring the collective impact of the context including the caregiving and parental responsibility, and the perception of no option but to endure. Most factors were identified as both risk and protective factors, underscoring the dynamic nature of burnout.Conclusion: Participating parents ascribed burnout to unique combinations of risk and protective factors. Notably, these factors extended beyond the personal sphere to encompass societal structures that current conceptual models for dealing with burnout often ignore. From the perspective of parents, broad multisystem approaches to address parental burnout would likely appear most relevant.
The impact of engagement metrics overwhelms the influence of online disinhibition
Authors: Ruohan Wen
Published: August 2024

Clicking on paralinguistic digital affordances such as Like and Dislike on social media has become an important channel for social engagement. The present study examined the influence of online disinhibition and engagement metrics on Internet users’ attitude expressions via clicking Like and Dislike. Initially, a preliminary study was conducted, wherein participants engaged with a fictitious thread and clicked Like or Dislike on each post. We recorded the Likes and Dislikes each post received, which served as engagement metrics. In Study 1, an updated thread was introduced, displaying these metrics alongside the Like and Dislike buttons. The results indicated that engagement metrics had a significant impact on attitude expressions, while online disinhibition had no significant direct or moderating effects. Study 2 explored scenarios with these metrics reversed, again finding that the influence of online disinhibition remained insignificant. The study concludes with a discussion on the limitations of applying online disinhibition theory to online behavior.
Applying the Relevance Realization Theory of Cognitive Function to Moral Decision-Making Across Adulthood
Authors: Kara-Yakoubian Mane
Published: August 2024

One of the markers of human cognitive agency is the capacity for moral cognition. Across a range of societies, older adults are perceived as more moral than younger adults. Interestingly, research shows that compared to younger adults, older adults are more likely to endorse deontological (as opposed to utilitarian) ethics. This age difference has been explained in terms of cognitive decline and socioemotional shifts. In this paper, I consider the Exploration-Exploitation (EE) model of aging, as well as the Relevance Realization (RR) framework, in explaining moral decision-making phenomena across younger and older adults. My analysis reveals that in older age, the mechanisms underlying moral decision-making gravitate toward efficiency-based processing more generally, as opposed to exploitation-based processing more specifically, thereby lending support in favour of the RR framework over the EE model of aging. I conclude that in light of the explanatory breadth offered by RR, the opponency of exploration-exploitation alone, a trade-off relationship subsumed by RR, is at times necessary but insufficient in explaining age differences in response to sacrificial moral dilemmas. Accordingly, I suggest that augmenting EE with RR could expand both its theoretical precision and explanatory power, while ameliorating its possible theoretical blind spots. I conclude by discussing the empirical limitations of the RR framework and proposing potential empirical avenues for future research on RR in the context of moral decision-making.
Frequency-dependent selection in the English spelling system across 1000 years of history
Authors: Carr Jon W , Rastle Kathleen
Published: August 2024

English orthography has largely been left to evolve freely across its thousand-year history with little top-down design or reform. Yet modern English spelling has become standardized, even if its standardized spellings are sometimes internally inconsistent. The relative freedom with which English orthography has been allowed to evolve makes it an interesting test-case for exploring whether spelling standardization might arise through a process of positive frequency-dependent selection. To maximize the chance of being understood, it pays for a writer to adopt spelling variants that occur with higher frequency, leading to those forms becoming increasingly entrenched. To evaluate this possibility, we assembled a diachronic dataset of English spelling variation, SpellEng, which we make freely available. SpellEng reports on the frequency of 112,080 spelling variants (across 32,264 lemmata) over the entire history of the English language. We use this dataset along with a model of frequency-dependent selection to estimate the extent to which English standardization can be explained by such a process. Our findings suggest that the past 1000 years of English spelling have been characterized by both positive and negative frequency-dependent selection. We discuss how linguistic dynamics and external events have shaped these periods of stability and change.
A Study of the Dyadic Associations of Self-Compassion on Sexual Satisfaction and Dissatisfaction: Evidence of Differential Associations
Authors: Loveless Courtney , Quinn-Nilas Christopher
Published: August 2024

Recent research has supported the positive effects of self-compassion for couples’ relationships; however, these efforts have only recently been applied to couples’ sexuality. Although there is some evidence supporting the associations between self-compassion and sexual satisfaction when satisfaction is conceptualized unidimensionally, it is unclear if and to what degree those associations are different for satisfaction and dissatisfaction when these constructs are assessed separately. The aim of this study was to understand the associations between self-compassion separately for sexual satisfaction and sexual dissatisfaction for romantic partner dyads. A sample of 230 married midlife Canadian couples participated in an online survey. Findings from distinguishable Actor Partner Interdependence Models indicated that women and men with higher levels of self-compassion reported more sexual satisfaction and less sexual dissatisfaction but the effects were stronger for satisfaction than dissatisfaction. Only men’s self-compassion affected women’s sexual dissatisfaction, but not vice versa. Findings are discussed in terms of their relevance to societal attitudes and application to sex and couples’ therapy.
A computational analysis of lexical elaboration across languages
Authors: Khishigsuren Temuulen , Regier Terry , Vylomova Ekaterina , Kemp Charles
Published: August 2024

Claims about lexical elaboration (e.g. Mongolian has many horse-related terms) are widespread in the scholarly and popular literature. Here we introduce BILA, a dataset including 1606 bilingual dictionaries, and show how it can be used to study lexical elaboration at scale. We first validate our approach by showing that it confirms 146 out of 163 previous claims from the literature. We then identify previously unreported examples of lexical elaboration, and analyze how lexical elaboration relates to ecological and cultural variables. Claims about lexical elaboration are sometimes dismissed as either obvious or fanciful, but our work suggests that large-scale computational approaches to the topic can produce non-obvious and well-grounded insights about language and culture.

Student's Perception towards ICT Use in Government and Non- Government Schools of Surkhet District
Authors: Acharya Gobinda Prasad
Published: August 2024

This article delves into students' perceptions of Information and Communication Technology (ICT) use in government and non-government schools in Surkhet District. The main objective of the article is to explore the perception of students towards the use of ICT in government and non-government school in Surkhet district. In this article, a mixture of article methods is used including both quantitative and qualitative approaches. All the secondary level students in 18 schools of Surkhet district was the population of the article. Among the students of 18 schools, 424 were selected as sample. Questionnaires were used as the source for the data collection. The article used the statistical tools like Regression analysis to find out the perception of the students towards ICT use in schools. Data collected from both school types revealed demographic distributions and attitudes toward ICT. Government school respondents were primarily aged 12-13, while non-government schools had more respondents across all age groups. Males were the majority in both. The regression model analyzing students' perception of ICT use displayed a moderately strong positive correlation (R = 0.610), with 37.2 percent variance explained by factors like Access to Personal Device, Digital Literacy, Access to School IT Resources, and ICT Integration in Curriculum. Constructs showed good reliability and validity, affirming measurement accuracy. Results highlighted the positive impact of examined factors on ICT use, underlining the significance of resource access, digital literacy, and curriculum integration. Non-government schools had higher mean scores in computer and internet skills, possibly due to infrastructure or resource differences. Notable disparities existed between government and non-government schools in combined school and home ICT use and confidence levels, with gender differences also noted, warranting further exploration or intervention. The article underscores the need for improving access to resources, enhancing digital literacy, and integrating ICT in curricula to positively influence students' perceptions and use of ICT.

Authors: Halim Irwanto , Berlianto Margaretha Pink
Published: August 2024

In the dynamic telecommunications sector, customer retention is of paramount importance for companies like First Media in Indonesia, given the rapid technological advancements and increasing demand for high-quality services. This study explores the factors influencing customer retention, including service encounter communication, internet service quality, service convenience, perceived value, customer satisfaction, and brand love. Service encounter communication, service convenience, and internet service quality are examined in relation to their effect on perceived value, customer satisfaction, and customer retention. A comprehensive survey was conducted using Google Forms, with 49 indicators distributed across these variables, and data analysis was performed using Partial Least Squares - Structural Equation Modeling (PLS-SEM). The results indicate that service encounter communication has a positive and significant effect on perceived value, customer satisfaction, and customer retention. Service convenience positively affects customer satisfaction but does not affect perceived value or customer retention. Internet service quality has a positive influence on perceived value. Perceived value enhances customer satisfaction, leading to improved customer retention and brand love, which in turn positively influences customer retention. This study provides valuable insights for First Media to enhance customer retention and satisfaction. However, it has limitations in terms of variable selection and testing, suggesting opportunities for future research to explore additional factors contributing to customer retention and brand management.

Are Canadian Voting System Reform “Trade-Offs” Really Trade-Offs? Operationalizing Voting System Values and Assessing the Evidence
Authors: Pilon Dennis M.
Published: August 2024

Le débat entourant la réforme du mode de scrutin au Canada est présenté comme un choix entre des valeurs opposées, mais tout aussi valables, qui sont incarnées ou produites par divers systèmes de scrutin, généralement représentés comme des compromis. L’élément central d'un tel discours, c'est que le choix retenu, quel qu'il soit, entraînera inévitablement des avantages tout autant que des coûts (p. ex, des résultats plus proportionnels, mais une moins grande représentation locale, ou des majorités plus stables au pouvoir, mais une moins grande compétition entre les partis). Pourtant, ce qui frappe à l'examen de cette approche, c'est le peu d'opérationnalisation de ces revendications fondées sur la valeur et le manque de données probantes pour les corroborer. Puisque le débat public sur les choix politiques produit de meilleurs résultats en présence d'une source immédiate de données probantes, qui aide les participants à évaluer les revendications contradictoires, ainsi que les avantages et les coûts potentiels, l'absence de soutien empirique à ces échanges est profondément problématique. Pour remédier à ce déficit d'information, le présent article cherche à opérationnaliser la signification concrète des valeurs alléguées en appui aux divers modes de scrutin possibles dans le débat canadien, et ce, en quatre volets : la complexité du scrutin, la stabilité du gouvernement, la représentation locale et le principe de responsabilité représentative, puis explore les données comparatives sur leur fonctionnement et leurs conséquences afin d'en évaluer la légitimité.

Purpose: To assess vitamin D, folate, vitamin B12, and iron status in Old Order Anabaptist (OOA) pregnant/postpartum women.

Methods: Blood was analyzed for plasma 25 hydroxy vitamin D (25(OH)D), red blood cell (RBC) folate, serum vitamin B12, and iron status indicators. Dietary intakes (food and supplements) from 3-day estimated records were compared to Dietary Reference Intakes and Canada’s Food Guide (2007).

Results: Fifty women participated in this descriptive cross-sectional study. Concentrations of 25(OH)D were low (<50 nmol/L for 20% and < 75 nmol/L for 63%); 42% had total vitamin D intakes < estimated average requirement (EAR). All women had RBC folate above the 1360 mmol/L cut-off. Nineteen percent had folate intakes upper limit. One woman had low serum vitamin B12 (<148 pmol/L); serum vitamin B12 was high (>652 pmol/L) for 24%. None had vitamin B12 intakes <EAR; intakes were high compared to the recommended dietary intake. One woman had low hemoglobin; 13% had ferritin <15 μg/L. Thirteen percent had total iron intake <EAR.

Conclusions: Overall, dietary intake and serum micronutrient status of OOA pregnant and postpartum women in our study were similar to those reported in previous studies of Canadian women. While some women had low intakes of vitamin D and iron, most had high intakes of folate and vitamin B12. These findings provide guidance to ensure appropriate dietary and supplement intakes in this potentially vulnerable and rarely studied population.

Erratic weather, such as intense heat followed by heavy rain, is causing air pollution in the sky of Jakarta. According to the SNI 03-6389-2011, which deals with energy conservation in building envelopes, the overall thermal transfer value (OTTV) for walls should not exceed 35 W/m2. This study aims to analyze OTTV in Class T and Class S. Class S uses clear glass, while Class T has a shading device in the form of a sunglass sticker. The method used involves calculating the total outer wall area, glass area, window-to-wall ratio (WWR), solar factor value, and then obtaining the OTTV. The results of the study show that the WWR value for Class T was 0.5, while for Class S it was 0.4. The OTTV value in Class T is 58.74 W/m2, whereas the OTTV in Class S is 70.64 W/m2. Despite both classrooms not meeting the SNI requirements, the classrooms using shading devices have OTTV values closer to the SNI standard.
Роль візантійської освітньої моделі у формуванні раціоналістичної лінії в українському освітньому просторі періоду ранньої історії
Authors: Антонюк Галина
Published: August 2024

The article traces the birth of rationalist ideas in the Ukrainian school in the era of early history, namely during the formation of the Kyiv state (X-XI centuries). It is noted that the Byzantine school (IV-VII, and later – X-XII centuries) represented the reception of the classical Hellenic paideia as a unity of content and form and in its main features preserves its functioning in modern educational systems. It is emphasized that the borrowing of the Byzantine model in the field of national education and training was not a simple and unambiguous phenomenon, but a contradictory one, it felt the strong influence of the Slavic pagan culture, which did not know the school as a social institution and did not perceive it as a necessity. The dominant form was home schooling, which met the social needs of the time. The introduction of Christianity as the state religion led to the need for educated people to serve the needs of the state apparatus, which at a certain stage led to the emergence of a school for the systematic organization of education and knowledge transfer. The domestic elite school of the period of the princely era was oriented to the Byzantine educational model, which provided for the introduction of the "seven liberal sciences" (subjects of the trivium and quadrivium) into the Ukrainian education with the introduction into the curriculum of the relevant scientific knowledge that was taught in the educational institutions of the time, which subsequently created a formal basis for the establishment of a rationalist line in Ukrainian education, as a source for the formation and establishment of the ideology of the Enlightenment, the clear manifestation of which is observed in the period of the XVII-XVIII centuries.
Transvenous embolization of a carotid-cavernous fistula via the inferior ophthalmic vein: illustrative case
Authors: Liang Buqing , Moskalik Anzhela D , Taylor Maritza N , Waldau Ben
Published: August 2024

BACKGROUND

A 49-year-old woman with a history of hypertension presented to the emergency department with right eye redness, proptosis, orbital fullness, and blurry vision. She had initially been diagnosed with an orbital pseudotumor, and the symptoms worsened over a course of steroids. Computed tomography angiography raised concern for a carotid-cavernous fistula (CCF), which was subsequently confirmed by digital subtraction angiography.

OBSERVATIONS

She underwent fistula coil embolization via the internal maxillary artery and inferior ophthalmic vein (IOV). At the 2-month follow-up, she reported complete resolution of diplopia, orbital fullness, and proptosis. An ophthalmology examination revealed normal visual fields bilaterally.

LESSONS

CCF embolization is rarely performed through the IOV, with only 5 reported cases in the literature. This case demonstrates that the procedure can be easily performed if the anatomy is favorable over the superior ophthalmic vein, with the illustration of good cosmetic outcomes.
