Purpose. To estimate the probability of a change in the calculated IOL after microinvasive vitrectomy 25G in patients with operated macular rupture. Methods. A retrospective analysis of patients operated on for a macular rupture with a diameter from 400 microns to 1000 microns was performed. The exclusion criteria were: the axial length of the eye is less than 22.0 mm and more than 26.0 mm, recurrence of previously operated macular ruptures, the presence of concomitant ocular pathology that can affect the final postoperative result (macular degeneration, glaucoma, diabetic and postocclusive retinopathy), the presence of previously performed surgical interventions on the retina. The study involved 64 eyes, of which 34,37 % (22 eyes) with a native lens; 14,06 % (9 eyes) with artifacia before vitrectomy; 6,25 % (4 eyes) vitrectomy with cataract phacoemulsification and IOL implantation and 45,31 % (29 eyes) cataract phacoemulsification with IOL implantation was performed within 4–9 months after primary vitrectomy. These patients were the study group. The comparison parameters are best corrected visual acuity, K1, K2, Ave. K1, Ave. K2, Axis, Ave. K2-K1, axial length of the eye, Ave. axial length of the eye, as well as calculated models of IOL and implantable after vitreoretinal surgery. Results. The change in the optical strength of the IOL occurred in 44,82 %. The change in the IOL model is 37,93 %. The change in the optical strength and model of the IOL is 20,68 %. The change in the optical strength of the previous IOL model is 24,1%. The change in the strong axis of more than 20 ° with the previous IOL parameters is 13,79 %. Only in 27,58 % there were no changes in the calculation of IOL. Conclusion. An individual approach to the calculation and selection of intraocular lenses in patients with vitreoretinal pathology allows implantation of all types of IOLs with maximum patient satisfaction with the functional result.

Purpose. To determine the effectiveness of the anatomical and functional results of treatment of refractory diabetic macular edema after removal of the inner limiting membrane using the latest generation anti-VEGF drug. Material and methods. We examined 6 patients with 1st type and 2nd type diabetes mellitus. The average age of the subjects was 47.45 ± 27.15 years. Of these, there were 4 women and 2 men. 1st type diabetes mellitus was detected in 2 people, in other patients — 2nd type. 3 patients had previously undergone pan-retinal photocoagulation (from 1st to 2nd stages). All patients received intravitreal injections (anti-VEGF) of Eylea (4–5 injections) during the last year. According to the optical coherence tomogram (OCT), macular edema was recorded, recurring on average after 1.36 ± 0.85 months. All patients underwent surgical treatment. In the presence of lens opacity, surgical treatment was started with phacoemulsification of cataracts. A microinvasive subtotal vitrectomy was performed with the removal of the posterior layers of the vitreous body and proliferative membranes fixed to the retina. The removal of the inner boundary membrane was performed after its staining in the size of two to three diameters of the optic disc without any tamponade. After 2 months, two patients had an increase in retinal thickness in the fovea. These patients received one injection of Vabismo. Results. The compared groups did not differ in morphofunctional characteristics. In the postoperative period, there was a tendency to increase visual acuity and decrease retinal thickness, regression of hard exudates in 4 patients. In 2 patients, an increase in retinal thickness in the fovea was noted after 2 months. After intravitreal injection of the latest generation anti-VEGF drug (Vabismo), these patients also showed an increase in visual acuity, regression of solid exudates and a decrease in retinal thickness. Conclusion. Microinvasive subtotal vitrectomy with removal of the inner limiting membrane in combination with intravitreal injection of the latest generation anti-VEGF drug (Vabismo) is an effective method of treating refractory diabetic macular edema.

Electronic Structure Methods for Simulating Flavin’s Spectroscopy and Photophysics: Comparison of Multi-Reference, Single-Reference, and TD-DFT Methods
Authors: Kabir Mohammad Pabel , Ghosh Paulami , Gozem Samer
Published: June 2024

The use of flavins and flavoproteins in photocatalytic, sensing, and biotechnological applications has led to a growing interest in computationally modeling the excited state electronic structure and photophysics of flavin. However, there is limited consensus regarding which computational methods are appropriate for modeling flavin’s photophysics. We compare the energies of low-lying excited states of flavin computed with time-dependent density functional theory (TD-DFT), equation of motion coupled cluster (EOM-EE-CCSD), scaled opposite-spin configuration interaction (SOS-CIS(D)), multiconfiguration pair-density functional theory (MC-PDFT), and several multi-reference perturbation theory (MR-PT2) methods. In the first part, we focus on excitation energies of the first singlet excited state (S1) of five different redox and protonation states of flavin, with the goal of finding a suitable active space for MR-PT2 calculations. In the second part, we construct two sets of one-dimensional potential energy surfaces connecting the S0 and S1 equilibrium geometries (S0–S1 path) and the S1 (π,π*) and S2 (n,π*) equilibrium geometries (S1–S2 path). The first path therefore follows a Franck-Condon active mode of flavin while the second path maps crossings points between low-lying singlet and triplet states in flavin. We discuss the similarities and differences in the TD-DFT, EOM-EE-CCSD, SOS-CIS(D), MC-PDFT and MR-PT2 energy profiles along these paths. We find that (TD-)DFT methods are suitable for applications such as simulating the spectra of flavins but are inconsistent with several other methods when used for some geometry optimizations and when describing the energetics of dark (n,π*) states. MR-PT2 methods show promise for the simulation of flavin’s low-lying excited states, but the selection of orbitals for the active space and in the number of roots used for state averaging must be done carefully to avoid artefacts. Some properties, such as the intersystem crossing geometry and energy between the S1 (π,π*) and T2 (n,π*) states, may require additional benchmarking before they can be determined quantitatively.
Unlocking the chemistry of graphene: the impact of charge carrier concentration on molecular adsorption on graphene
Authors: Szary Maciej J.
Published: June 2024

Both intentional and unintentional doping of graphene is a common occurrence, as its carrier concentration can be modulated through various mechanisms. While extensively explored in electronics for achieving desirable conductivity, other aspects of doping remain largely untapped, presenting opportunities for further innovation. This study demonstrates that carrier concentration serves as a powerful and selective tool for modulating the interaction between molecular adsorbates and graphene. The effects are tunable and evident for both n-type and p-type doping, with low-to-medium modulation at doping levels of ±1012 e/cm2 , and substantial enhancements, with interaction strength increases exceeding 150% and hundreds of meV, at doping levels of ±1013 e/cm2 . These effects are also molecule-specific, with significant enhancements for species such as water (H2O), ammonia (NH3), and aluminum chloride (AlCl3 ), while having minimal impact on species like hydrogen (H2 ). This finding not only elucidates the fundamental chemical behavior of graphene but also provides a versatile method to tailor its surface chemistry for applications in sensors, catalysis, and electronic devices. The insights from this research pave the way for advanced material design strategies, leveraging the tunable nature of graphene’s properties to optimize its interaction with various molecular species.

Cotylenins (CNs) are bioactive fungal diterpene glycosides that exhibits stabilizing activity on 14-3-3 protein-protein interactions (PPIs), which has significant therapeutic potential. Despite its importance, the biosynthetic pathway of CNs have remained unclear. Here, we report the identification of the biosynthetic gene cluster and elucidation of the biosynthetic pathway of CNs. Our investigation reveals the roles of glycosyltransferase, methyltransferase, and prenyltransferase enzymes in the assemble and modification of the glycoside moiety, as well as the multifunctional oxidation activity of the P450 enzyme CtyA. We also demonstrate the synthesis of an active unnatural CN derivative through combinatorial biosynthesis, showcasing the potential of pathway enzymes as catalytic tools to expand the structural diversity of the diterpene glycosides. Additionally, we highlight the stabilization effects of pathway intermediates on 14-3-3 PPIs, providing insights into the evolutionary optimization of bioactivity within the biosynthetic pathway. These findings pave the way for future efforts to achieve the production Cotylenin A and related compounds with enhanced bioactivity through synthetic biology or semisynthesis.

Gusher syndrome is a rather rare condition complicating surgical interventions on the stapes. It is characterized by profuse effusion of perilymphatic fluid from the vestibule into the lumen of the tympanic cavity during fenestration or removal of the foot plate of the stapes and rapid filling of the volume of the tympanic cavity and the external auditory canal with perilymph. This is due to increased pressure of perilymph fluid in the inner ear cavity in some developmental anomalies. Preoperative diagnosis of gusher syndrome can be difficult when the CT scan does not show any abnormalities in the anatomy of the inner ear canal and inner ear structures. The rarity of this phenomenon greatly complicates the procedure of its study, as well as the development of optimal schemes of therapeutic and diagnostic tactics in a real clinical situation. A clinical case of a combination of congenital isolated middle ear developmental anomaly and gusher syndrome is studied. A patient with suspected otosclerosis underwent stapedoplasty at Saint-Petersburg Research Institute of Ear, Throat, Nose and Speech. During the operation, abundant perilymphorrhea "Gusher" symptom was obtained, as well as thickening of the stapes legs and thin tendon of the stirrup muscle were revealed. The postoperative diagnosis was changed from otosclerosis to congenital isolated anomaly of middle ear development (isolated ankylosis of the stapes), gusher syndrome. The tactics of management of a patient with otosclerosis and isolated middle ear anomaly are similar. CT of temporal bones and virtual CT endoscopy should become the standard of examination of patients before surgical treatment. The use of cartilage and supracartilage is a safe way to stop perilymphorrhea in patients with gusher syndrome.

Published: June 2024

Visando subsidiar o professor para trabalhar tópicos de física moderna no ensino médio, apresentamos e avaliamos dois documentários sobre física quântica: o episódio “Salto Quântico”, da série “A Fábrica do Cosmos”, e o episódio “O Pesadelo de Einstein”, da série “Os Segredos da Física Quântica”. Para não restringir a análise a uma única leitura, realizamos uma breve pesquisa qualitativa junto a quatro licenciandos em física, buscando uma caracterização potencialmente útil para o professor desejoso em trabalhar o assunto na educação básica. Apesar de serem documentários de boa qualidade, apresentados por físicos atuantes na área, apontamos que podem levar a compreensões inadequadas caso o professor não esteja atento em como trabalhar os assuntos junto aos estudantes. A partir das respostas dos licenciandos a um questionário, sugerimos que esses recursos audiovisuais podem auxiliar o professor no trabalho do tema em turmas do ensino médio.

Published: June 2024

This study explores the role of perceived change in job demands and resources and socio-demographic characteristics in teacher well-being during the Covid-19 pandemic. We used data from over three thousand Croatian school teachers with at least three years of service. We performed path analysis to test the proposed relationships of socio-demographics (gender, school level and years of service) and perceived change in job demands and resources (work demands, the frequency of student difficulties and the quality of professional cooperation) with teacher well-being (job satisfaction, stress and work-life balance). The effects of the socio-demographic variables on the measures of well-being varied from non-existent to small. The model fitted the data well. However, the parameter values indicated a modest contribution of socio-demographics and perceived change in job demands and resources in explaining teacher well-being during the Covid-19 pandemic. Teachers reported relatively high job satisfaction, low levels of stress, and medium levels of work-life balance. In addition, their experiences of stress and work-life balance were not considerably affected by the perceived increases in job demands. Our results suggest that teachers demonstrated resilience in adapting to challenging circumstances. This capacity should be continuously nurtured in their professional development programmes.

Authors: Jennifer Miller , Jillian Skelton , Madison Bibbs
Published: June 2024

This qualitative case study explored the experiences of Historically Black College or University (HBCU) students taking online courses during the initial stages of the COVID-19 pandemic. The purpose of this study was to better understand students' perceptions of the influence of the four sources of academic self-efficacy on their academic performance during this period of exclusive online learning. Participants (n = 13) were female students enrolled full-time in an undergraduate degree program at a small HBCU in the southeastern United States. All participants confirmed that they had been taking courses exclusively online due to COVID restrictions in 2020, with no in-person courses for at least six months prior to data collection. Four themes emerged: Mastery Experiences for online students requires self-regulation and independent learning skills with dynamic instruction and constructive feedback, effective Vicarious Experiences were student-directed extracurricular multi-modality interactions with peers, effective Verbal Persuasion for online students was the rapport with instructors, Physiological State for online students was their ability to manage competing demands and distractions. Each theme provided insights for college administration, faculty, and students into developing strategies for enhancing the online learning experience for undergraduate college students by intentionally informing their sense of academic self-efficacy which is strongly related to academic performance in the online classroom.

Several Rock Art sites were discovered and partially studied in southern Thailand, especially in Phang Nga Bay. Fewer are known further south, in the coastal area along the Lanta Bay and in the Trang and Satun provinces. This article provides preliminary results of surveys conducted in 2021 on caves located in the coastal zone and offshore in Lanta Bay as part of the Thai French Archaeological Mission that focuses on the maritime landscape and exchange networks. The project is done in collaboration with communities in Ko Lanta, amongst which are the indigenous maritime people called “Urak Lawoi.” This participatory approach shed new light on the potential rock art traditions this region possesses, and on the relationship between landscape and rock Art. The rock art may correspond to landmarks for navigation, especially along exchange routes linking the bay to Phang Nga, Phuket, Krabi,Trang, Satun, and Malaysia, and/or form part of rituals undertaken during successive sequences of use by various local and foreign groups. This project also focuses on the special relationship between local groups, and especially the Urak Lawoi, developed with hills and caves, in particular on islands. ภาค้ใต้ขีองปัระเทศิไทยมีีการค้้นพบัแล่ะศิ่กษาแหล่่งศิิล่ปัะบันหินหล่ายแห่ง พบัว่าสี่วนใหญ่อย้่ในบัริเวณอ่าวพังงา จังหวัดพังงา สี่วนทางใต้ตามีแนวชี่ายฝัั่􀅩งอ่าวลั่นตา จังหวัดกระบัี􀄙 ล่งไปัจนถ้ำ่งจังหวัดตรังแล่ะสีต้ล่ ยังมีีรายงานค้้นพบั แหล่่งค้่อนขี้างน้อย ในบัทค้วามีนี􀄚 จ่งได้นำาเสีนอผู้ล่ลั่พธ์เบัื􀄚องต้น จากการสีำารวจบัริเวณอ่าวลั่นตา ใน พ.ศิ. 2564 เปั็น สี่วนหน􀄙่งขีองโค้รงการโบัราณค้ดีไทย-ฝั่ร􀄙งั เศิสี ซึ่ง􀄙่ มีุ่งเน้นเพ􀄙อื ศิก่ ษาภ้มีิทัศิน์ทางทะเล่แล่ะเค้รือขี่ายการแล่กเปัลี่􀄙ยนทางทะเล่ในแถ้ำบัทะเล่อันดามีัน ด้วยวิธีการมีีสี่วนร่วมีกบัั ชีุ่มีชี่นกลุ่มีต่าง ๆ ในพ􀄚นื ที􀄙เกาะลั่นตา โดยเฉพาะชี่าวอ้รักล่าโวยจทำาให้ทราบัถ้ำ่งค้วามีสีัมีพันธ์ระหว่า ภ้มีิทัศิน์กับัวัฒนธรรมีศิิล่ปัะบันหินในพ􀄚นื ที􀄙 โดยพบัว่าแหล่่งศิิล่ปัะบันหินมีักปัรากฏ อย่้บันเกาะที􀄙มีีตาำ แหน่งที􀄙ต􀄚งั ท􀄙มีี ีค้วามีสีอดค้ล่้องกบัั การเปั็นจุดสีังเกตในการเดินเรือทางทะเล่ แล่ะอย้่ในเสี้นทางแล่ก เปัลี่􀄙ยนทางทะเล่ที􀄙สีามีารถ้ำเชีื่􀄙อมีต่อไปัยังอ่าวพังงา ภ้เก็ต กระบัี􀄙 ตรัง สีต้ล่ แล่ะปัระเทศิมีาเล่เซึี่ย แล่ะมีักปัรากฏอย้่ตามี เกาะที􀄙มีีการใชี่้พ􀄚นื ที􀄙ในการปัระกอบัพิธีกรรมีขีองกลุ่มีต่าง ๆ ท􀄚งั ภายในแล่ะภายนอก อีกทั􀄚งพบัว่าภ้มีิทัศิน์ร้ปัแบับัต่าง ๆ เชี่่น ถ้ำ้ำา หรือเนินเขีาบันเกาะ มีีค้วามีสีัมีพันธ์กับัชี่าวอ้รักล่าโวยจ ในด้านวิถ้ำีชีี่วิตแล่ะค้วามีเชีื่􀄙อที􀄙มีีต่อสีถ้ำานที􀄙ต่าง ๆ ในอ่าวลั่นตาด้วยเชี่่นกัน

Higher education initiatives can contribute to the Sustainable Development Goals (SDG) by funding long-term learning programs that support students' personal, social, and professional development in the workplace. Therefore, this study aimed to investigate the role of sustainable professional as a dependent variable between sustainable social and personal aspects within higher education programs. The empirical study outlined sustainable professional, social, and personal development elements as well as measurement and structural models. The data were collected using a cross-sectional methodology. Subsequently, surveys were conducted and analyzed using the Analysis of Moment Structure (AMOS) 24.0 program. The samples included 754 students from three faculties at Universitas Muhammadiyah Purwokerto, Indonesia, specializing in teachers training and education, business and economics, and pharmacy. The results supported the hypothesis that autonomous personal training and sustainable social communication can improve students' professional learning. The urge to educate students could prompt teachers to engage in more professional activities. Therefore, even in a world where changes are both inevitable and impossible to predict, higher education programs can sustain or improve teachers' performances.

Published: June 2024

This study was a preliminary phase of an ongoing PhD investigation focusing on incorporating Indigenous Knowledge into Creative Arts education in specific rural schools. The paper examined teachers' perceptions on the proposed initiative, aiming to identify obstacles to the indigenisation process and explore potential strategies to overcome these challenges. Despite the South African curriculum's emphasis on appreciating Indigenous Knowledge Systems, Creative Arts teachers often rely on Eurocentric textbook content and approaches. The study, based on Social Judgment Theory, involved nine purposefully chosen teachers from the intermediate and senior phase of these schools. The theory posits that people's tendency to accept or reject new information exists on a continuum. The study aimed at elucidating the various factors and processes influencing individuals' diverse perceptions and reactions to the same information or concerns. The research employed a qualitative method collecting data through semistructured interviews supplemented by informal conversations. To analyse the gathered data, a thematic approach was applied, involving thorough reading and coding processes to identify and categorise themes. The findings revealed insufficiency of resources and infrastructure, incongruity between the content knowledge and the learners' contextual knowledge and inadequate skills and knowledge among indigenous teachers. The researcher advocates for the integration of the knowledge, skills, and participation of the school and community members, to collectively provide relevant information for the comprehensive growth of learners in their cultural understanding and identity.

Mathematics lecturers face various difficulties in implementing effective distance learning such as the lecturer's motivation in an online class. This research aims to explore the challenges encountered by lecturers when implementing effective distance learning. A qualitative case study approach was used to explore issues regarding effective distance learning in Higher Education Institutions (HEIs). Eight mathematics lecturers from three different institutions were chosen to be the participants using purposive sampling. The participants consisted of five lecturers from Kolej Matrikulasi Negeri Sembilan (KMNS), two lecturers from Kolej Matrikulasi Pulau Pinang (KMPP), and one lecturer from Universiti Kebangsaan Malaysia (UKM). The research data was collected through semi-structured interviews followed by field notes. Thematic analysis techniques were used to identify the constructs, themes and patterns present using the NVivo software. The interview findings highlighted six main themes, specifically the students' engagement and motivation, lack of communication, lack of immediate feedback, difficulty when demonstrating and in visualisation, developing the learning materials and limited internet connectivity. Lecturers may consider incorporating engaging activities to keep students interested throughout the lesson. Additionally, backup plans should be developed to address issues related to internet connectivity, which can disrupt the teaching and learning process.

Технологический суверенитет и развитие технологий в критической информационной инфраструктуре являются важнейшими вопросами в текущей геополитической ситуации. Переход на российское программное обеспечение в топливно-энергетическом комплексе требует определения области наиболее высокой зависимости от импорта и приоритетных направлений сосредоточения усилий государственно-частного партнерства. Вместе с тем в настоящее время во всех отраслях промышленности, и в частности в топливно-энергетическом комплексе, не внедрена единая методология расчета локализации программного обеспечения. Выбор методик для расчета остается за компанией или органами власти и подходы к расчету импортной составляющей не являются унифицированными. В связи с этим отсутствует единая сравнительная база и возможность корректной оценки уровня импортозамещения программного обеспечения компаниями. В статье представлен обзор нормативно-правовых документов в части требований по внедрению российского программного обеспечения. Выявлены проблемные аспекты определения российского программного обеспечения. Предложена методика расчета уровня локализации программного обеспечения, отличающаяся от принятых в России как по количеству критериев, так и по итоговому расчету: разработанная методика включает наибольшее количество метрик и критериев и дает наиболее корректный результат. Отличительной особенностью методики является ориентированность на цепь создания стоимости программного обеспечения.

Technological sovereignty and the development of technologies in critical information infrastructure are the most important issues in the current geopolitical situation.
