Abutment-Bar Structure Connection Geometry: An Important Design Parameter for Implant-Supported Bar-Retained Overdentures With Cantilever Extension
Authors: Akgün Gökçen , Kayacan Ramazan
Published: February 2023

When extended distally due to higher loading in the posterior region, implant-supported bar-retained overdentures with cantilever bar extension exhibit greater bending moments on the implants closest to the cantilever bar and increased stresses in the overdenture components. In this study, a new abutment-bar structure connection was introduced to minimize undesired bending moments and reduce the resulting stresses by increasing the rotational mobility of the bar structure on the abutments. Copings of the bar structure were modified to have 2 spherical surfaces, sharing the same center, located at the centroid of the top surface of the coping screw head. The new connection design was applied to a 4 implant-supported mandibular overdenture to create a modified overdenture. Both the classical and modified models had bar structures with cantilever extensions in the first and second molar areas and were analyzed for deformation and stress distribution using finite element analysis, which was also conducted for both the overdenture models without cantilever bar extensions. Real-scale prototypes of both models with cantilever extensions were manufactured, assembled on implants embedded in polyurethane blocks, and subjected to fatigue testing. Both models' implants were subjected to pullout testing. The new connection design increased the rotational mobility of the bar structure, minimized the bending moment effects, and reduced the stress levels in the peri-implant bone and overdenture components, whether cantilevered or not. Our results verify the effects of rotational mobility of the bar structure on the abutments and validate the importance of the abutment-bar connection geometry as a design parameter.

In this article the author shows selected economic views of Jan Bobrzyński, conservative statesman and ideologist from the interwar years. In further part of the article some reason of economic crisis, named by Bobrzyński, are being listed (e.g. interventionism, state management, violation of private property). The author shows also economic objectivity, pointed by Bobrzyński as the way to the modernization of Poland. In the conclusion, the author stresses that Jan Bobrzyński’s opinion on II Rzeczpospolitej economic system aren’t good effort of connecting liberalism with catholic church’ social doctrine. Jan Bobrzyński was trying to find the golden mean between hypertrophy of individualism unit and the socialist supremacy of the state. In his opinion, Cracow conservative school created an optimal model, growing the unit’s individualism in the name of common good.
EFFECT OF CATALYZER ON PRIMARY COMBUSTION AND MECHANICAL PROPERTIES OF HIGHLY METALIZED FUEL-RICH PROPELLANTS
Authors: Ramakrishnan Murugesan , Chakravarthy Satyanarayanan R. , Kandasamy Jayaraman , Sarathi Ramanujam
Published: February 2023

Highly metalized fuel-rich propellants containing 40-50% nano-micro aluminum and the catalyzed compositions comprise ultra-fine iron oxide (UFIO) content of 0.3-2.0% were considered. Primary combustion features and mechanical properties of these propellants were investigated for water ramjet propulsion applications. These propellants exhibit almost 70% burning rate enhancement at all the tested pressures with UFIO catalyzed ones as compared with uncatalyzed compositions. Simultaneously, the burning rate pressure exponent of these UFIO catalyzed propellants was considerably reduced. The quenched agglomerates from the primary combustion exhibit over wider size ranges from few microns to few millimeters, which are of several times larger as compared with parent Al particles. The number density effect of Al particles causing the agglomeration at the burning surface outweighs the particle size and catalyzer effect in these highly aluminized propellant compositions. The crack free propellant grain structure was achieved by optimizing the molding pressure range and the rate of compaction. Addition of UFIO increased the compressive strength marginally whereas it reduced the elastic properties of the propellant grain marginally.
A mixed formulation of limit analysis for seismic slope stability
Authors: Nguyen H. C.
Published: February 2023

This paper presents a mixed formulation based on the node-based smoothed finite-element method for estimating seismic slope stability. The final form of Hellinger–Reissner is cast as the min–max optimisation problem with conic constraints. Solving the second-order cone programming directly determines both master fields, stress and displacement. It is shown from the numerical results that the stability numbers obtained are almost equal to the exact collapse loads for the relatively flat slopes. Moreover, the effects of the dilation angle on the seismic stability number are studied by incorporating a simple iterative technique in the algorithm cast as max-min programming, arriving at the observation that both the static and the seismic stability numbers are susceptible to the dilation angle. Although the magnitude of the seismic stability number largely depends on the vertical seismic acceleration for a broad range of typical slope angles, the seismic stability number for the relatively flat slopes in cohesive-frictional soils is likely independent of the seismic acceleration in the vertical direction.
Use of unmanned aerial vehicles for delivering prohibited items to correctional institutions and possible ways to combat them
Authors:   Kuzbass Institute of the Federal Penitentiary Service of Russia, Filipiev Roman A.
Published: February 2023

Prohibited items and substances have been smuggled into correctional institutions since their inception and will be smuggled as long as these institutions continue to function. Technological progress sets ever new challenges for restricted access facilities, including the institutions of the RF Federal Penitentiary Service. In recent years, penitentiary institutions have recorded dozens of attempts to deliver prohibited items (drugs, mobile devices, alcohol, etc.) by unmanned aerial vehicles to a closed area. Currently, the Federal Penitentiary Service of Russia is developing and implementing equipment that will allow detecting and blocking drones, quadrocopters and other unmanned aerial vehicles near correctional facilities and pre-trial detention centers. Protection against the quadcopter's unwanted penetration into the restricted access area is to take control over it and land it in a designated place. When an unmanned aerial vehicle (UAV) approaches the territory of the correctional facility, the detection system is triggered, it determines the UAV's unique identification number and then proceeds to seize control over it. At any time of the day and regardless of weather and other conditions, excluding the influence of the human factor, the protection system is able to independently detect the UAV and land it in a designated place. The system is able to intercept it not only when it is trying to cross the perimeter, but also when it is approaching a restricted access facility at a distance of several hundred meters. The fight against small-sized quadrocopters has long been massive; there are dozens of ready-made solutions for protecting any objects, including correctional facilities. One of these solutions may be a perimeter security radar complex: the control of airspace over a facility and its adjacent territory with the help of radar stations is a traditional way of detecting air targets.
Компетентностный подход к системе образования в рамках обучающей системы pick
Authors: Каширская Е.В. , Хархурин А.В.
Published: February 2023

Вопрос становления и оценки гибких компетенций не теряет своей актуальности, несмотря на значительное число научных разработок по данной тематике. На практике учителя и сами учащиеся все еще сталкиваются с трудностями совмещения в едином учебном процессе двух векторов развития. С одной стороны, важна образовательная деятельность, нацеленная на освоение конкретных предметных знаний. С другой стороны — возможность развивать и отслеживать уровень прогресса в формировании значимых личностных и когнитивных навыков, связанных с коммуникативными аспектами, креативностью, гибкостью ума и критическим мышлением. В статье представлен компетентностный подход к системе образования в рамках новой обучающей системы «Ключи к полилингвальному, межкультурному и творческому образованию» (Plurilingual Intercultural Creative Keys; PICK). Это авторский подход к решению актуальной задачи формирования значимых гибких компетенций у детей и подростков. Проведен подробный теоретический анализ трех значимых компетенций — полилингвальной, межкультурной и креативной — через описание составляющих их знаний, навыков, личностных и деятельностных установок. Актуальность выбора именно этих трех компетенций определяется как практическими аспектами современной жизни, связанными с глобализацией, мультикультурализмом и нестабильностью, так и результатами эмпирических исследований, проводимых на протяжении последних 20 лет, которые доказали влияние многоязычной и межкультурной практики на формирование определенных когнитивных функций и личностных качеств, лежащих в основе творчества. Результатом исследований стала концепция полилингвальной креативности, где языковые и творческие практики рассматриваются как с позиции личности, включенной в эту деятельность, так и с позиции социокультурного контекста ее реализации.
Восьминедельная практика медитации осознанности в контексте развития саморегуляции
Authors: Халутина Ю.А.
Published: February 2023

В статье представлены результаты исследования влияния систематического восьминедельного опыта практики медитации осознанности на характеристики саморегуляции. Мы предположили, что ее эффекты могут быть различными: систематический медитативный опыт связан с улучшением эмоционального состояния, с повышением продуктивных и снижением непродуктивных форм рефлексии, а также с развитием навыков самоконтроля и саморегуляции. Для проверки этих гипотез было проведено исследование с предварительным и повторным замером: перед началом курса и в конце восьмой недели. Использование для анализа качественных и количественных методов исследования позволяет говорить о реализации его смешанного дизайна (embedded mixed-methods) с количественной основой. Участниками исследования выступили ученики восьминедельной онлайн-программы обучения осознанной медитации: 61 респондент (47 женщин, 14 мужчин) в возрасте от 21 до 52 лет (M = 35.31, SD = 7.57). Полученные результаты позволяют говорить о том, что прохождение восьминедельной программы осознанной медитации связано с разносторонней трансформацией системы самоконтроля и саморегуляции, что проявляется в развитии навыков самомотивации, саморелаксации, когнитивного самоконтроля, концентрации, ориентации на действие при неудаче, интеграции противоречий, в развитии осознанности и гармонии, в улучшении эмоционального состояния, а также в снижении непродуктивных форм рефлексии. Результаты качественного анализа согласуются с количественными, позволяют показать, какие изменения в себе к концу курса отмечают сами респонденты, и открывают поле новых возможных переменных для будущих исследований. В целом, полученные данные указывают на развитие контакта с настоящим моментом и возрастание гибкости в процессе саморегуляции.

Apparent Diffusion Coefficient Measurement of Myelofibrosis in Mouse Tibia v1
Authors: L Chenevert Thomas
Published: February 2023

The goal of this Co-Clinical Imaging Research Program (CIRP) pre-clinical imaging protocol (PIP) is to provide detailed description of key steps used to achieve a stated level of technical repeatability (precision) embodied in “Claims”, for MRI measurement of apparent diffusion coefficient (ADC) in tibia bone marrow of myelofibrosis mouse models. This pre-clinical imaging procedure document will be referred to as a “profile” and adheres to a PIP MRI template provided in: https://www.protocols.io/workspaces/pre-clinical-imaging-protocols. This profile details procedures for ADC measurement from diffusion weighted imaging (DWI) acquisition and image processing in MF mouse tibia to achieve stated performance claims. Tibia bone marrow composition in MF mouse models has gradation going from proximal to distil ends of the tibia, therefore separate claims are made for volume of interest (VOI) analysis of ADC maps for each of three distinct sections along the length of the tibia (see Figure 1): Section 1 (proximal)º VOI (~4-5mm3) within 9mm of proximal end of tibia Section 2 (transition)º VOI (~0.4-0.5mm3) from 10 to 12mm of proximal end of tibia Section 3 (distil)º VOI (~0.1-0.2mm3) from 13 to 14mm of proximal end of tibia Claim 1:A measured change in the mean ADC in Section 1 VOI of MF mouse model tibia that exceeds ±0.037µm2/ms indicates a true biological change has occurred in the tibia bone marrow with 95% confidence. Claim 2:A measured change in the mean ADC in Section 2 VOI of MF mouse model tibia that exceeds ±0.087µm2/ms indicates a true biological change has occurred in the tibia bone marrow with 95% confidence Claim 3:A measured change in the mean ADC in Section 3 VOI of MF mouse model tibia that exceeds ±0.030µm2/ms indicates a true biological change has occurred in the tibia bone marrow with 95% confidence
Christopher Alexander As An Architectural Thinker
Authors: Samalavičius Almantas
Published: February 2023

In this commentary the author discusses why Christopher Alexander remains on the margins of contemporary architectural discourse despite his original, important, and lasting contributions to the field. Being a somewhat controversial figure in architecture and architectural theory, Alexander has occupied the status of a seminal albeit not always adequately understood and interpreted author. The rejection and misinterpretation of his ideas are due to multiple reasons, including his refusal to act and write as a standard scholar and his lack of interest in appealing to his professional community. While his attitude perhaps explains the neglect of his intellectual legacy, it does not justify it. A reconsideration of his legacy could benefit from rethinking his intellectual identity. This commentary suggests that Alexander should be approached as an original architectural thinker rather than a standard architectural academic. Thus, he could be comparable to other renowned figures of the modern era, including such influential yet often misunderstood social thinkers as Ivan Illich or Jacques Ellul.
Botulinum neurotoxin is both poison and medicine: botulinum therapy and iatrogenic botulism
Authors: Nikiforov Vladimir V.
Published: February 2023

Botulinum neurotoxin is the most potent poison known worldwide. Over the past two centuries, its structure and functions have been studied in detail, and obtained in its pure form. Knowledge of the mechanisms of action of botulinum neurotoxin has determined two directions of its possible use: negative, as a biological (toxin) weapon, and positive, as an agent that eliminates pathological muscle hypertonicity and neuropathic pain and can be used for aesthetic purposes (beauty injections).
The lecture presents the chronological development of both directions and provides a detailed analysis of the various uses of botulinum neurotoxin as a medical and cosmetic treatment. Particular attention is paid to the side effects of botulinum therapy and ways to overcome them.
Factors limiting the motor rehabilitation of elderly disabled persons with lower limb loss
Authors: Kramer Irina V. , Khokhlova Olga I. , Vasilchenko Elena M.
Published: February 2023

Background. Amputation of a limb leads to significant changes in a person's life, since mobility restrictions affect the ability to perform daily tasks and professional duties.
Aim. To identify factors that negatively affect the results of motor rehabilitation of elderly disabled people with lower limb loss.
Material and methods. Data on patients with postamputation lower limb defects, who were divided into two groups, were analyzed. The first group (comparison group) included patients aged 60 years and younger 171 people, including 141 men and 30 women; the second group (main group) consisted of patients over 60 years of age 260 people, including 207 men and 53 women. Patients of the second group with a satisfactory result of rehabilitation were included in subgroup 2A, with an unsatisfactory result in subgroup 2B. The influence of gender, age, level of mobility, cognitive abilities, daily activity, level of amputation, presence of concomitant diseases, body mass index, duration of the post-amputation period on the result of rehabilitation in the second group were assessed. Statistical analysis used the 2 test, the MannWhitney U test for independent groups, and binary logistic regression.
Results. The indicators of mobility before prosthetics in elderly people with disabilities did not differ significantly from those in people under the age of 60, however, by the end of the rehabilitation course, the optimal level of mobility in the room (without using a wheelchair) was reached by 75.4% of the comparison group and only by 52.7% of the main group (ꭓ2=22.59, р 0.001). Further analysis showed that at the age of over 66.5 years, the risk of obtaining an unsatisfactory result of motor rehabilitation is 2.3 times higher (p=0.006) than at the age of 6066.5 years. In older women, this risk is 2.7 times higher than in men of the same age (p=0.014). With a body mass index of more than 28.5 kg/m2, the risk increases by 3.2 times (p=0.001), and with a duration of the post-amputation period at the time of primary prosthetics of more than 1 year, it increases by 2.6 times (p=0.008) compared with lower values of these indicators in elderly people with disabilities.
Conclusion. The factors associated with the unsatisfactory result of motor rehabilitation of elderly disabled people with lower limb loss are: age over 66.5 years, female sex, body mass index over 28.5 kg/m2, duration of the post-amputation period at the time of primary prosthesis over 1 year.
Exploring Teaching Experience in Distance Learning during COVID-19: A Qualitative Case Study
Authors:   the Ministry of Education, Oman, Ambusaidi Abdullah , Abri Maimoona H. Al
Published: February 2023

This study sought to explore the awareness of teachers in K-12 during the pandemic about several aspects of online learning: instructional strategies, motivational factors for students, and the application of Universal Design for Learning (UDL) to lesson plans produced by teachers. This exploratory case study used a focus-group discussion and an evaluation form with a sample of thirty (N=30) teachers. The results showed that the teachers were unaware of some of the instructional strategies for online learning. The teachers and their students were not sufficiently prepared or qualified for the emergency transition to online learning. The results suggest that it is important to prepare professional development for teachers about instructional strategies and learning theories for online learning and blended learning.
Soviet Subsidy and Voluntarism: The Economic Anomalies of Revolutionary Cuba
Authors: Sovilla Bruno
Published: February 2023

The article analyzes the Cuban economy from 960 until the fall of the Soviet Union. It shows that after abolishing private ownership of the means of production at the beginning of the revolutionary period, Cuba could not establish a planning system because of Fidel Castro’s widespread intervention. The economic consequences were grave. Only the enormous economic aid received from the Soviet Union ensured the survival of the Cuban revolution and the implementation of the System of Direction and Planning of the Economy (SDPE), which was successively dismantled during the rectification process. What happened in Cuba during this period seems to have been an endemic problem of its political system, in which there was no effective counterweight to the comandante en jefe, on whom all major political and economic decisions depended. That problem was the main reason for Cuba’s poor economic performance.
Organization of Customs Procedures in the Grand Duchy of Lithuania in the Second Half of the 18th Century
Authors: Kiturko Irina
Published: February 2023

The article analyzes the process of developing and improving the customs procedure in the second half of the 18th century in the Grand Duchy of Lithuania. The author notes that during this period the customs service of the Grand Duchy of Lithuania in the framework of the general reform of the state apparatus was built on the principles of bureaucracy and became one of the most perfect state structures, a special institute in the system of the executive power. This contributed to the improvement, expansion and development of customs documentation and the entire customs administration in the GDL. The article describes different types of customs documents, highlights the process of their unification through the introduction of common rules for registering customs procedures in the second half of the 18th century. It also emphasizes the importance of customs documents as a source for studying the economic history of the Grand Duchy of Lithuania.
“Between Past and Future”: Discussions on Politics of Memory in Russia and Belarus
Authors: Vorobieva Olga
Published: February 2023

The article presents a comparative analysis of the politics of memory in Belarus and Russia. The main periods of its transformation in 1990—2010s are specified. The question about the strategy of interaction between the main actors of memory policy is posed. The perspectives of memory studies development, related to the question about the future, which is very rarely raised in modern studies, although it is fundamental for all actors, are outlined. Another important gap in contemporary memory studies seems to be the question of practices of commemoration, which form not only national and local communities, but also decentralized affective relations of a new type. The authors advocate the thesis that the key role in contemporary Russian and Belarusian memory politics is played by the restriction of presentistic subordination of past and future to pragmatic interests of the present.

Pulmonary vascular resistance/systemic vascular resistance (PVR/SVR) ratio changes after sildenafil therapy in uncorrected congenital heart disease-associated pulmonary arterial hypertension
Authors: Rahmawati Evita Devi Noor , Gharini Putrika Prastuti Ratna , Hartopo Anggoro Budi , Dinarti Lucia Kris , Anggrahini Dyah Wulan
Published: February 2023

Pulmonary vascular resistance (PVR) to systemic vascular resistance (SVR) ratio is a prognostic predictor in congenital heart disease (CHD)-associated pulmonary arterial hypertension (PAH) after defect correction. Sildenafil, widely used as a PAH drug, can decrease PVR with minimal or without changes in SVR, resulting in decreased PVR/SVR ratio after treatment. However, there is limited evidence that PVR/SVR ratio reduced after sildenafil therapy in uncorrected CHD-associated PAH patients. This study aimed to investigate the decreasing of the PVR/SVR ratio after ≥ 1-year oral sildenafil therapy in adult uncorrected CHD-associated PAH. A total of 30 uncorrectable CHD-associated PAH subjects derived from the COHARD-PH registry were included in this study. Right heart catheterization (RHC) was performed during the first visit and further evaluations were conducted after ≥1-year oral sildenafil therapy. The PVR/SVR ratio at the baseline and after the evaluation was collected. The primary outcome of this study was the changes in PVR/SVR ratio from baseline to evaluated RHC. Characteristic analysis of subjects with decreased PVR or PVR/SVR ratio was perforemd as the secondary outcome. The mean PVR and SVR were not different from baseline and evaluated RHC (15.98± 10.67 vs. 18.38±13.93 WU, p=0.206 and 36.65±13.99 vs. 39.34±15.46 WU, p=0.262). There was no significant difference in the baseline PVR/SVR ratio and the evaluated PVR/SVR ratio after ≥1-year sildenafil therapy (0.48 ±0.32 vs. 0.49±0.36; p=0.882). As much as 15 subjects (50%) experienced decreased PVR/SVR ratio. However, there was no significant difference in the characteristics, including age, Eisenmenger syndrome, type of shunts, baseline PVR, PAH-specific treatment, and baseline NT-proBNP level (p>0.05). In conclusion, sildenafil therapy does not change PVR/SVR ratio in adults with uncorrected CHD-associated PAH.

Obstructive sleep apnea (OSA) is a common chronic disorder that decreases the quality of life of patients. It is an underdiagnosed medical condition in Nigeria. This study aimed to describe the clinical presentations and validate the sleep apnea screening questionnaires with a home sleep study for the diagnosis of patients with suspected OSA seen in Lagos. This was a descriptive cross sectional study carried out on adult patients with suspicion of OSA referred to the Respiratory Clinic of Lagos State University Teaching Hospital. A proforma was used to obtain information and also data from home polysomnography was obtained for each patient. We selected 22 patients. The commonest presentations include snoring (20 or 90.9%), daytime somnolence (16 or 72.7%) and choking while sleeping (12 or 54.5%). The commonest comorbidities were hypertension (16 or 72.7%) and obesity (6 or 27.3%). The STOP-Bang  score identified more patients with a high clinical probability for OSA than the Epworth score (20 and 12 patients respectively). Polysomnography showed evidence of sleep apnea in most suspected patients with severity ranging from mild, to moderate to severe disease (3 or 13.6%, 3 or 13.6%, and 10 or 45.5% respectively). The use of combined Epworth and STOP-Bang questionnaires combination is great tool in identifying patients with suspected cases of OSA based on clinical presentations that will eventually benefit in a resource-limited environment like Lagos. There should be increased awareness of the use of this readily available and cheap questionnaire among physicians in Lagos for ease of OSAS diagnosis for many patients.
The effect of appropriate antibiotic use on the length of hospital stay in deep neck abscess (DNA) patients
Authors: Palupi Hesti Dyah , Wulandari Dian Paramita , Trihandoko Feri
Published: February 2023

Deep neck abscess (DNA) is an emergency in the otorhinolaryngology head and neck surgery field due to the formation of abscesses in the potential space between the deep neck fasciae. It is typically caused by the expansion of infection from various sources, including the teeth, mouth, throat, paranasal sinuses, middle ear, and neck. The increase of DNA cases needs for improvement of patient management especially when the patients have comorbidities which lead to an extended length of treatment. The study aimed to evaluate the appropriateness of empirical antibiotics given according to culture results and any comorbid factors that affect the length of hospital stay (LOHS). It was case-control observational study involving 44 cases of DNA patients who treated at Dr. Sardjito General Hospital Yogyakarta in the period of January 2018 to December 2020. The patients were divided into two groups with 22 patients in each group. The first group was the DNA patients with > 7 d LOHS and the second one was those with ≤ 7 d.  No significantly relationship was observed between variables evaluated included the appropriate antibiotic use  (p=0.546). However, dental caries (DC) was significantly related with the LOHS (p=0.015). In conclusion, there is no relationship between the appropriate antibiotic use and the LOHS. However, the DC is risk factor that influence the LOHS in patients with DNA.
Petroleum potential of the Lower Devonian reservoirs on the Chernyshev Swell (Timan-Pechora Petroleum Province)
Authors: Nechaev M. , Maydl T. , Kotik I.
Published: February 2023

The Chernyshev Swell is one of the poorly studied and promising areas for the hydrocarbon (HC) exploration in the north of the Timan-Pechora Petroleum Province. Lower Devonian carbonate deposits as part of the Middle Ordovician-Lower Devonian petroleum complex are considered as a priority object for the HC exploration. The study of the Lower Devonian deposits in well core and outcrop showed that the reservoirs were represented mainly by fractured-cavern-pore and cavern-fractured dolomites. The porosity of the rocks reaches 9.3 % with a predominance values in the range of 0.5–1.5%. The permeability values up to 1.0×10–15 m2 are predominant, less often in the range of 1–10×10–15 m2. Such filtration and capacitive properties characterize them as low-capacity and low-permeable reservoirs. The best properties of reservoirs are associated with facies of carbonate shallows, small biostomes and biogerms. The petroleum source rocks are contained in the clay-carbonate unit of the Ovinparma Formation. The OM richest rocks (Corg — 1.08–1.88%) are characterized by the values of (S1+S2) generation potential — 2.18–8.65 mg HC/g rock and hydrogen index HI — 153–432 mg HC/g Corg, which classifies them as medium petroleum source rocks. Thus, the presence of reservoirs, petroleum source rocks and overlapping by the Upper Devonian regional seal is a favorable condition for the formation of HC deposits in the Lower Devonian.
Beyond “Learning Loss:” Literacy Teacher Noticing in a Post-Pandemic World
Authors: Aukerman Maren , Aiello Liam
Published: February 2023

A resounding emphasis on learning loss has pervaded popular discourse and academic research as children return to in-person instruction after COVID-related schooling interruptions, most notably including remote schooling. This paper examines how this emphasis links to persistent deficit-oriented views of children as lacking literacy and language. It proposes an expanded, anti-deficit conception of teacher noticing based upon four domains that deserve more visibility especially at this time in the literacy classroom: children’s emotions, children’s funds of knowledge, children’s relationships, and children’s purposes. It provides examples of how teachers might adopt deliberate noticing practices that attend to these domains.
Understanding Children’s Drawings as Sociomaterial Assemblages of Voice during Pandemic Times
Authors: Burke Anne
Published: February 2023

During the COVID-19 pandemic, schools transitioned to online learning. Utilizing sociomaterial assemblages and visual methods alongside interviews to prompt children’s voices, we collected drawings from primary students at two Eastern Canadian schools to achieve a multimodal understanding of children’s online learning experiences. Younger children’s drawings reflected the issues with technology and lack of socialization, while older children’s depicted their enjoyment with online learning with the agency afforded by learning from home. We found that pedagogical creativity and innovation were essential to successful online learning. This research demonstrates the efficacy of a sociomaterial perspective on children’s drawings for eliciting children’s agentic voices.
O uso da indicação geográfica na proteção e na apropriação do patrimônio cultural agroalimentar
Authors: Peralta Patricia Pereira
Published: February 2023

O patrimônio agroalimentar, aqui considerado patrimônio cultural imaterial, possui valor para as comunidades que o detêm e para o mercado. Por possuir valor mercadológico, tal patrimônio demanda alguma forma de proteção que permita a sua apropriação. Os Direitos de Propriedade Intelectual (DPI), constituídos para proteger as criações do espírito, vem sendo considerados como um sistema passível de garantir proteção ao patrimônio agroalimentar. O objetivo deste texto é discutir a possibilidade de uso dos DPI, especialmente, das indicações geográficas (IG), como forma de apropriação do patrimônio agroalimentar a partir de uma revisão teórica e da observação de dois casos de patrimônio imaterial: o ofício das panelas de Goiabeiras e os modos de fazer os queijos do Serro e da Canastra.

Authors: Aji Wahyu Trisno
Published: February 2023

The existence of women is treated differently from the existence of the opposite sex, namely men. This differentiation occurs since time immemorial where humans have recognized themselves as the most conscious species. Humans called women themselves are treated like objects. Women must be subordinate to men, and men must dominate women. However, over time, this view has become worthy of a revolution. The view that considers women as second humans must be removed. Women are also human and demand the same rights as men as human beings too. In this article, it will be explained how women should be equal to the roles of men. Feminism is a form of how women fight for themselves to face the rise of patriarchal ideology. Women are also human beings who can also become leaders; this is a revolutionary view of feminism to fight the ideology that subordinates women.
Gender Dan Politik Dalam Perspektif Hadist

Published: February 2023

Artikel ini menjelaskan pandangan hadis tentang kepemimpinan perempuan khususnya dalam bidang politik. Tema utama dalam artikel ini adalah penelusuran dan pemaknaan hadis terkait kepemimpinan perempuan yang menyatakan bahwa "Suatu kaum tidak akan beruntung, jika dipimpin oleh seorang wanita”. Dari penelusuran sanad, hadis ini berkualitas shahih, namun dari segi matan pemahaman hadis ini bersifat lokal atau temporal dan tidak bersifat universal. Hadis ini disampaikan sebagai respon pengangkatan putri Kisra, seorang perempuan yang secara sosial tidak mendapatkan legitimasi dari masyarakat, sehingga pemaknaan dari hadis ini adalah kepimpinan dalam politik dapat diemban oleh siapa saja dengan syarat memiliki kebijaksanaan, pendidikan dan leadership yang baik.

Al-Qur’an sebagai sumber ajaran umat Islam, di dalamnya berisi petunjuk menuju ke arah kehidupan yang lebih baik, tinggal bagaimana manusia memanfaatkannya. Menanggalkan nilai-nilai yang ada di dalamnya berarti menanti datangnya masa kehancuran. Sebaliknya kembali kepada Quran berarti mendambakan ketenangan lahir dan batin, karena ajaran yang terdapat dalam Quran berisi kedamaian. Agar terbentuk pribadi yang mulia, hendaknya penanaman akhlak terhadap anak digalakkan sejak dini dengan cara menanamkan nilai pendidikan akhalak yang terkandung dalam Quran,  karena  pembentukannya  akan  lebih  mudah  dibanding setelah anak tersebut menginjak dewasa.

ABSTRACT

Background: Intravenous glucocorticoids pulses administration is the main therapeutic option in the treatment of Graves’ orbitopathy. Such therapy could relate to the multiple adverse effects. The aim of the study is evaluation the influence of intravenous methylprednisolone (IVMP) pulse therapy on the heart rhythm (HR) changes in patients with active, moderate-to-severe Graves’ Orbitopathy (GO).

Methods: We studied 20 patients with moderate-to-severe GO. All patients received 12 IVMP pulses (6x500 mg plus 6x250mg) at equal time intervals in a weekly schedule. We performed Holter ECG monitoring for 3 consecutive days (the day before, the day of IVMP and day after IVMP) to monitor HR and arrhythmias. We compared changes in HR between these 3 days and set time interval when the alteration was significant. This evaluation was performed during the 1st, 6th and 12th IVMP pulse.

Results: Increased HR, in comparison with the day before, was registered on the day of IVMP administration. The most significant increase in HR started 5 hours (h) after a pulse administration and lasted 12 h. There were no significant differences in HR between the day before and the day after IVMP. We did not notice any major adverse cardiac events including severe arrhythmias.

Conclusions: IVMP therapy is associated with increased HR, that occurs a few hours after infusion, lasts several hours and is transient.

Efficient utilization of radio resources in wireless networks is crucial and has been investigated extensively. This letter considers a wireless relay network where multiple user pairs conduct bidirectional communications via multiple relays based on orthogonal frequency-division multiplexing (OFDM) transmission. The joint optimization of channel and relay assignment, including subcarrier pairing, subcarrier allocation as well as relay selection, for total throughput maximization is formulated as a combinatorial optimization problem. Using a graph theoretical approach, we solve the problem optimally in polynomial time by transforming it into a maximum weighted bipartite matching (MWBM) problem. Simulation studies are carried out to evaluate the network total throughput versus transmit power per node and the number of relay nodes

Development of K-Ras independence may explain failure of targeted therapy for pancreatic cancer (PC). In this paper active N as well as K-Ras was shown in all human cell lines tested. In a cell line dependent on mutant K-Ras, it was shown that depleting K-Ras reduced total Ras activity, while cell lines described as independent had no significant decline in total Ras activity. Knockdown of N-Ras showed it had an important role in controlling the relative level of oxidative metabolism but only K-Ras depletion caused a decrease in G2 cyclins, proteasome inhibition reversed this and other targets of APC/c were also decreased by K-Ras depletion. K-Ras depletion did not cause an increase in ubiquitinated G2 cyclins but instead caused exit from G2 phase to slow relative to completion of S-phase, suggesting mutant K-Ras may inhibit APC/c prior to anaphase but stabilizes G2 cyclins independently of this. We propose that during tumorigenesis, cancer cells expressing wild type N-Ras protein are selected because the protein protects cancer cells from the deleterious effects of cell cycle independent induction of cyclins by mutant K-Ras. Mutation independence results when N-Ras activity becomes adequate to drive cell division even in cells where K-Ras is inhibited. Keywords: Pancreatic Ductal Adenocarcinoma, K-Ras, N-Ras, G2 cyclins.
A Predictive Model of Community Disaster Resilience based on Social Identity Influences
Authors: Cvetković Vladimir M.
Published: February 2023

The territory of Serbia is vulnerable to various types of natural and man-made disasters. The risk is not equal across the entire territory, depending on the type of hazard and the expected potential for damage. So far, the level of community disaster resilience has not been determined in Serbia. There are no scientific preconditions for its improvement to reduce the future material and intangible consequences of disasters. Regarding that, the project’s main objective is to develop and validate a predictive model of community disaster resilience based on social identity influences through an investigation impact of social identity indicators on the level of community disaster resilience in Serbia. The project is based on the upcoming research on whether the level of community disaster resilience can be predicted based on social identity indicators, how social identity indicators affect different dimensions of community disaster resilience, and how disasters shape social identity. The project is based on multimethod research in which quantitative (face-to-face interviews in 40 of the 191 municipalities), and qualitative (semi-structured interviews) research methodology will be applied. A developed predictive model with an index of community disaster resilience in Serbia will empower the creation of preconditions for designing public policies, strategies and procedures for improving resilience and reducing the consequences of disasters on people and their property and enhancing citizens’ security. The project will encourage the prediction of community disaster resilience based on social identity indicators, improving disaster foresight and preparing to limit disaster losses. Based on the development of analytical frameworks for understanding community disaster resilience and social identity in disasters, essential preconditions for designing innovative information systems will be created to enable local communities to increase their level of resilience.
Entrepreneurial Learning, Entrepreneurial Inspiration, and Incubation Resources on Higher Vocational Students' Entrepreneurial Intentions: Evidence from China
Authors: Liu Wen , Miao Zhenlong
Published: February 2023

To reveal the influence of variables such as entrepreneurial learning, entrepreneurial inspiration, and incubation resources on students' entrepreneurial intentions in vocational colleges, this study took vocational colleges in Zhejiang Province, a province with a strong entrepreneurial climate in China, as an example. The study used a questionnaire to obtain data, and 614 valid questionnaires were collected from seven vocational colleges. The study divided entrepreneurship education into three dimensions: entrepreneurial learning, entrepreneurial inspiration, and incubation resources, and used structural equation modeling to investigate the influence of entrepreneurship education on entrepreneurial intentions while introducing entrepreneurial efficacy as a mediating variable to examine the influence mechanism of entrepreneurship education on entrepreneurial intentions of higher education students. The results showed that entrepreneurial learning, entrepreneurial inspiration, incubation resources, and entrepreneurial efficacy were all significantly and positively correlated with entrepreneurial intentions and that entrepreneurial efficacy mediated between the two dimensions of entrepreneurship education (entrepreneurial learning and entrepreneurial inspiration) and entrepreneurial intentions. Therefore, to enhance the effectiveness of entrepreneurship education in vocational institutions, we should stimulate students' sense of entrepreneurial efficacy, strengthen their entrepreneurial learning and inspire them to start their businesses. In turn, university incubation resources can be developed and utilized to enhance students' entrepreneurial confidence and intentions.
Traceable Spectral Radiation Model of Radiation Thermometry
Authors: Mlačnik Vid , Pušnik Igor
Published: February 2023

Despite great technical capabilities, the theory of non-contact temperature measurement is usually not fully applicable to the use of measuring instruments in practice. While black body calibrations are in practice well established and easy to accomplish, this calibration protocol is never fully applicable to measurements of real objects under real conditions. Currently, the best approximation to real world radiation thermometry is grey body radiation thermometry, which is supported by most measuring instruments to date. Nevertheless, the metrological requirements necessitate traceability, therefore real body radiation thermometry is required for temperature measurements of real bodies. This article documents the current state of temperature calculation algorithms for radiation-thermometers and the creation of a traceable model for radiation thermometry of real bodies that uses a digital twin model of the system of measurement to compensate for the loss of data, caused by spectral integration, which occurs when thermal radiation is absorbed on the active surface of the sensor. To solve this problem, a hybrid model with variable scalar inputs is proposed, in which the scalar input parameters are calculated to correspond to the system of measurement. The method for calculating the effective parameters is proposed and verified with the theoretical model of non-contact thermometry. The sum of effective instrumental parameters is presented for different temperatures to show that the rule of radiation thermometry of grey bodies, according to which the sum of instrumental emissivity and instrumental reflectivity equals to 1, does not hold in radiation thermometry for real bodies. Using the derived models of radiation thermometry, the uncertainty of radiation thermometry due to the uncertainty of spectral emissivity is analysed by simulated measurements along the temperature ranges of various radiation thermometers, enabling traceable non-contact temperature measurements with known measurement uncertainty under any known conditions.
