Authors: Лопушинський І. П. , Дурман О. Л. , Чушак А. В.
Published: April 2023

У статті проаналізовано основні виклики, що постали перед вищою освітою України внаслідок широкомасштабного вторгнення Російської Федерації до України, які насамперед пов’язані із знищенням інфраструктури закладів вищої освіти (далі – ЗВО), втратою кадрового потенціалу, скороченням фінансування вищої освіти, відтоком українських та іноземних студентів із ЗВО, забезпеченням академічної доброчесності в ЗВО в умовах воєнного стану. Висвітлено, що з початком воєнної агресії Російської Федерації проти України система освіти України, як і всієї країни, функціонує в екстремальних умовах. Особливістю цього періоду є необхідність поєднання важливих завдань, які сягають минулого і потребують свого логічного завершення, з реальними завданнями, зумовленими війною, і завданнями, які визначатимуть подальший розвиток системи вищої освіти. Зосереджена увага на тому, що перспективи трансформації системи вищої освіти не обмежено лише напрямками цифровізації, хоча апробація та широке впровадження сучасних методів навчання з використанням інформаційних технологій є досить актуальними. Також потребують пильної уваги розвиток неформальної та інформальної вищої освіти, а також створення механізмів визнання її результатів у системі формальної вищої освіти. Розглянуто актуальні проблеми, що загострилися та виникли в системі вищої освіти України в умовах стрімкого наростання встановлених викликів. Виявлено, що першочергової уваги потребують проблемні питання в галузі вищої освіти, спричинені війною, а найбільшим викликом для системи освіти є створення безпечних умов усім учасникам освітнього процесу. Окреслено досягнення цілей, які передбачають виконання низки конкретних завдань щодо інтеграції ЗВО до світового освітньо-наукового простору та забезпечення їх фінансової автономії ЗВО. Щодо перспектив подальшого розвитку наголошено на необхідності створення підґрунтя всеохопної трансформації для дальшого розвитку фахової передвищої та вищої освіти. Наведено можливості, які може отримати вища освіта України для свого розвитку навіть за таких складних умов.

Authors: Красномовець В. А. , Трачук А. М.
Published: April 2023

У статті проведено аналіз та обґрунтовано суть поняття «тренд» у його трактуванні та прояву у туристичній сфері. Проаналізовано теоретичні підходи різних вчених до розуміння поняття «тренд» в площині туристичної діяльності та запропоновано авторське визначення даного поняття під яким пропонуємо розуміти «певне явище чи подію, що користується значним попитом у споживачів, є переважним напрямком у туризмі та є системо утворюючим у даному періоді часу». Узагальнено основні чинники, що впливають на формування трендів у туризмі та рівні формування та реалізації трендів у туризмі, що дозволяє більш предметно охарактеризувати існуючі тренди у туристичній галузі та згрупувати їх за предметними областями їх реалізації. Визначено чинники, що впливають на формування трендів у туризмі, які охарактеризовано за шістьма напрямами: економічні, соціальні, політичні, демографічні, технічні та глобалізаційні. Охарактеризовано рівні формування та реалізації трендів у туризмі, які пропонуємо характеризувати як мегатренд, макро- та мікротренд. Детально проаналізовано особливості формування трендів на макро- та мікрорівнях. Визначено, що на категоризацію трендів у туризмі вплив мають також такі чотири загальні тенденції (тренди) розвитку суспільства як: транспорт та логістика, профільні сфери для окремих видів туризму, стиль життя населення та маркетинг територій. Обґрунтовано основні інструменти - методи прогнозування трендів в туризмі. З’ясовано, що в галузі туризму найбільш відповідними для прогнозування є метод екстраполяції простого ковзного середнього за даними лише останніх кількох періодів, або метод експоненційного згладжування, де замість простого середнього більшу вагу мають недавні дані, а менший – давніші, методи декомпозиції та інші.
АГРОПРОМИСЛОВА ІНТЕГРАЦІЯ – ВАЖЛИВИЙ ЧИННИК ІНВЕСТИЦІЙНОЇ ПРИВАБЛИВОСТІ СІЛЬСЬКОГО ГОСПОДАРСТВА
Authors: Карнаушенко А. С. , Гребенюк Н. В. , Петренко В. С.
Published: April 2023

Сільське господарство належить до провідних галузей АПК, ефективність розвитку якої визначає економічну та продовольчу безпеку України. Вихід сільськогосподарської галузі з кризи, яка охопила її ще в кінці минулого століття, вбачається в необхідності формування сприятливого інвестиційного клімату. Політична нестабільність держави та правова незахищеність вкладів інвестора не сприяють активізації інвестиційного ринку. Важливою умовою підвищення ефективності інвестиційної діяльності у сільському господарстві є його кооперація та інтеграція з переробною та харчовою галузями, потужними, як вітчизняними так і іноземними, виробничо-переробними об’єднаннями, які здатні залучати великі інвестиційні кошти, спрямовуючи їх на виконання інноваційно-інвестиційних проектів і програм. Аграрно-промислова інтеграція є однією з основних форм інтенсифікації сільського господарства та переробної і харчової промисловості, методом покращення їх інвестиційної привабливості, поглиблення виробничих зв’язків та економіко-фінансових відносин між окремими учасниками об’єднання. Ефективне функціонування регіональних і міжрегіональних кластерів призведе до раціонального розподілу праці в межах окремих регіонів, створенню додаткових робочих місць, прискоренню темпів розвитку наукоємких технологій в сільському господарстві, раціональному використанню природних ресурсів. Для прискорення процесу кластеризації необхідно внести відповідні корективи в державну і регіональну економічну політику, розробити спеціальні загальнодержавні і регіональні програми, більш активно проводити наукові дослідження в різних регіонах України з метою скорочення термінів вирішення цієї проблеми. Аграрно-промислова інтеграція – це інноваційний напрям розвитку аграрних та переробних підприємств. Вона повинна охоплювати не тільки великі суб’єкти господарської діяльності, а й особисті селянські господарства, що дозволить більш ефективно використовувати природний та людський потенціал, спільну інфраструктуру, нові технології, сприятиме покращенню інвестиційного клімату в АПК.
La influencia de la inteligencia emocional sobre el síndrome burnout: una revisión sistemática
Authors: Soriano-Sánchez José-Gabriel , Jiménez-Vázquez David
Published: April 2023

Emotional intelligence consists of the individual's ability to intuit and understand one's own feelings, allowing him/her to give a positive response to the various problems arising from emotions or feelings, while burnout is a state of fatigue or frustration, caused by the dedication to a cause, way of life or relationship, generating chronic work stress. However, a good level of emotional intelligence seems to have a positive influence on the person.  Therefore, the aim of the present study was to analyze the relationship between emotional intelligence and burnout. After searching for scientific articles in international databases such as PsycINFO, Psicodoc, PubMed (MEDLINE), Scielo, Scopus, Sciencie Direct and Web of Science, as well as in the national electronic resource Dialnet, a total of 89 scientific articles were obtained which, after applying the established inclusion criteria, left 12 articles for review. The results of the studies included a sample size of 2.298 individuals from different fields, showing the relationship between both constructs. In conclusion, higher levels of emotional intelligence are related to lower burnout scores. Therefore, emotional intelligence is considered a protective variable against work-related stress that, consequently, develops the promotion of leadership, academic and professional engagement and personal well-being.

The UN project “17 Sustainable Development Goals” pursues the goal of a guaranteed solution to the problem of hunger, providing clean water and the like for the entire population of the Earth. The brief terms of this project (only 15 years) reinforce the responsibility of the main team, namely engineers. The qualification of any engineer will increase if he/she acquires additional knowledge in other technical areas in addition to the main profession. A compulsory educational program called “Engineering Literacy” (EL) is offered. It is planned that the EL will describe the main sectors of modern engineering. The same format is provided for the description of each technical sector under the heading, for example, the Space Industry Section, or the Nuclear Energy Section, or the Construction Sector Section, etc. The difficulty of each of the sections should be at the level of a high school graduate. Other requirements for each section are discussed in more detail in the article. As a demonstration, the article presents a preliminary short version of the Section “Nuclear Energy. Lessons from the past to avoid mistakes in the future”.
Obtaining colloidal silicon dioxide (Sio2) from quartz
Authors: Schwarzman L. Y. , Bazhenov E. V.
Published: April 2023

Colloidal amorphous silica is a product based on micronized silicon dioxide (SiO2) powder. The product is in large demand on the market due to its outstanding adsorption properties. It is widely known as AEROSIL®. The AEROSIL® technology is based on the use of silicon tetrachloride (SiCl4) as a raw material component, which determines the cost, energy and environmental assessments of the process. One of the ways to improve these technical and economic assessments is to find solutions that eliminate the use of SiCl4 from the process of producing micronized quartz powder. As an alternative technology, we consider plasma processes for the production of nano-powders of silica according to a scheme that eliminates the need to produce SiCl4. In the proposed scheme, amorphous silicon dioxide is produced using a technology with direct use of a natural source of silicon – quartzite. The technology is realized by a sequence of technological operations of activation of quartzite particles and deep energy-efficient purification of quartz at the molecular level, which allows to obtain ultrafine amorphous silica of high purity. Performing technological operations at low temperatures and without energy consumption for melting materials, complete regeneration of reagents allows us to meet the requirements of cost-effectiveness, energy efficiency and environmental friendliness of production.
Efficiency comparison of mixture formulations in the stabilisation/solidification of the loess silt contaminated with zinc in terms of mechanical properties
Authors: Lal Agnieszka , Fronczyk Joanna , Franus Małgorzata
Published: April 2023

The effectiveness of various types of binders in stabilizing/solidifying (S/S) contaminated soils is strongly dependent on the type of soil and contaminants present. The literature abounds with studies of stabilisation/solidification of clayey soils, which provides a background for initial assumptions in design of the method application for contamination of this type of soil. However, studies on the stabilisation/solidification of loess silt contaminated with heavy metals are not available. Filling this deficiency is important in order to ensure the rapid adoption of the most effective remedies in case of contamination and their immediate implementation in the subsoil. This paper has enabled the determination of the most effective mixture among the examined for the remediation of loess silt contaminated with zinc in terms of compressive strength. Strengths were determined with the implementation of 30% Portland cement (2.63 MPa), 30% of fly ash-cement mixture (2.21 MPa), an incinerated sewage sludge ash-cement mixture (0.93 MPa) and mixtures in which cement was replaced by an MgO activator (0.18 MPa for fly ash and 0.63 MPa for incinerated sewage sludge ash). In addition, the determination of strength was carried out for samples containing a mixture of fly ash, activator and cement (0.26 MPa) and incinerated sewage sludge ash, activator and cement (0.26 MPa), with weight ratios of 5:4:1 respectively. In summary, fly ash and cement in a 2:1 ratio can be considered the most effective binding mix in terms of unconfined compressive strength increase.

Characterizing the Force-Motion Tradeoff in Body-Powered Transmission Design
Authors: Abbott Michael , Stuart Hannah
Published: April 2023

Upper-limb prosthesis users continue to reject devices despite continued research efforts. Today, the passive topology of body-powered prehensors, which physically transmits grasp force and position data between user and device, results in improved performance over myoelectric alternatives. However, the loads and postures on the user's body also result in discomfort, fatigue, and worsened grasp force control. Despite the long history and everyday adoption of body-powered prehensors in society, the measurement of how specific body loads and postures affect grasp performance and user experience has yet to be systematically studied. In this work, we present a body-powered prosthesis emulator to independently change required input forces and motions to study the positive and negative effects provided by the inherent haptic feedback. Using a simulated grasping task, we collect functional and qualitative data from 15 participants using a shoulder harness interface. Outcomes show that reducing input loads and excursions to below 24 N and 45 mm, respectively, significantly reduces negative outcomes, but further reductions beyond those thresholds produce limited benefit. Coupling load and excursion, as is the case in real passive body-powered transmissions, demonstrates the importance of the force-motion tradeoff within the tested range of transmission ratios from 0.5:1 to 2:1. The purpose of this study is to inform future prehensor designs that leverage the transparency of body-power to deliver high functionality while mitigating user discomfort.

Authors: Jamaluddin Triwidyastuti , Narottama Bhaskara , Shin Soo Young
Published: April 2023

In this paper, an unsupervised federated quantum generative adversarial network (UF-QGAN) is proposed to handle optimization issues in wireless communications. The proposed UF-QGAN considers unsupervised learning so that it could work without labelling for the training dataset. By adopting the federated framework, the computational load could be distributed between the cloud and edge. As a representative example, the proposed UF-QGAN is applied for non-orthogonal multiple access (NOMA). Achievable sum rate and complexity are investigated for the performance measure. Simulation results show that the UF-QGAN, which not requires data labeling, achieved a similar achievable sum rate compared to the supervised learning scheme.

Published: April 2023

The small-scale prosumers' decentralized cooperation and aggregation in energy communities are essential to increase renewable energy penetration and to ensure a successful energy transition. Despite their potential small-scale prosumers are not motivated to participate in local energy value chains due to a lack of trust and decentralized cooperation models for capturing local sustainability preferences, most innovation efforts are focused on financial incentives that are anyway very low. In this paper, we propose a solution for prosumers’ decentralized coordination using a cooperative game on top of a blockchain overlay by considering their complementary energy-related features and flexibility for self-sufficient energy communities. We define a governance model based on cooperative games and blockchain-sharing mechanisms reinforce the prosumers' trust to support the decentralized self-organization in coalitions to balance the renewable generation and demand. Self-enforcing smart contracts are used for the blockchain integration of the governance model to allow the decentralized creation and management of prosumers’ coalitions for optimized payoff distribution towards self-sufficiency and using tokens capturing the beyond-financial community level exchanges. The evaluation results show our solution's effectiveness in enabling prosumers to cooperate and create self-sufficient coalitions in a decentralized fashion with low gas consumption and transactional time overhead.

Published: April 2023

As a high-impact pedagogical practice, study abroad is frequently utilized as an internationalization strategy to build post-secondary students’ global competence, but the impact of faculty-led short-term study abroad may vary widely across outcomes of interest. An understanding of student learning outcomes is especially needed now as COVID-19 begins to shift from pandemic to endemic and universities restart international initiatives. This systematic review synthesized and mapped evidence on global competence outcomes of short-term study abroad for undergraduate and graduate students. Studies (n=92) reported a total of 215 outcomes representing the three global competence domains of knowledge (41.4% of all outcomes), attitudes (38.1%), and skills (20.5%). Data sources used to assess global competence outcomes included self-administered surveys (40.1% of assessments), student journals (24.9%), and qualitative interviews (13.6%). While findings from this sample of studies offer evidence of positive impact of short-term study abroad on students’ global competence, the substantive and methodological evidence gaps identified can help to build conceptual clarity and guide design of future assessment approaches.
Abstract in Spanish
Como práctica pedagógica de alto impacto, estudiar en el extranjero se utiliza con frecuencia como una estrategia de internacionalización para desarrollar la competencia global de los estudiantes postsecundarios, pero el impacto de los estudios a corto plazo dirigidos por profesores en el extranjero puede variar ampliamente según los resultados de interés. La comprensión de los resultados de aprendizaje de los estudiantes es especialmente necesaria hoy en día que COVID-19 comienza a cambiar de pandemia a endémica y las universidades reinician las iniciativas internacionales. Esta revisión sistemática sintetizó y mapeó la evidencia sobre los resultados de competencia global de los estudios a corto plazo en el extranjero para estudiantes de pregrado y posgrado. Los estudios (n = 92) informaron un total de 215 resultados que representan los tres dominios de competencia global de conocimiento (41,4% de todos los resultados), actitudes (38,1%) y habilidades (20,5%). Las fuentes de datos utilizadas para evaluar los resultados de competencia global incluyeron encuestas autoadministradas (40,1% de las evaluaciones), revistas estudiantiles (24,9%) y entrevistas cualitativas (13,6%). Mientras los hallazgos de esta muestra de estudios ofrecen evidencia del impacto positivo de los estudios a corto plazo en el extranjero en la competencia global de los estudiantes, las brechas de evidencia sustantiva y metodológica identificadas pueden ayudar a construir claridad conceptual y guiar el diseño de futuros enfoques de evaluación.

Published: April 2023

The analysis of the hydrochemical regime of the rivers feeding the irrigated territories of agricultural land in the river basin is essential to develop scientifically based recommendations on the rational use of water and land resources. Anthropogenic influence on water and land resources in the basins of the rivers inevitably affects the change of surface water quality. A new method is proposed for analyzing the hydrochemical regime of the rivers based on three-dimensional (3-D) modeling of the Spatio-temporal distribution of water mineralization along the length of the main river. This method allows to analyze the flow of pollutants into the river, identify the main causes of pollution, and the formation of the hydrochemical regime of rivers.

This article presents the results of research on the development of new patterns of crepe fabrics for dress from natural silk and technology of their production. Today, the deep processing of cocoon raw materials, production of finished silk products, and development of new and in-demand fabric structures is an urgent and important problem. Crepe fabric - crepe de Chine consists of interwoven warp and weft yarn, which is produced by plain weaving. The structure of this fabric has long been known and its range is quite limited. In order to expand the assortment of crepe fabrics made from natural silk, their new structures have been developed, where the fabric contains warp threads of low twist right or left twist direction in 2 and/or 3 folds twisted into one low twist thread are taken as warp threads. A technological chain has been developed for the production of a new structure of dressing crepe fabric, technological parameters for rewinding, crushing, twisting of threads and the development of a new fabric structure on a loom, as well as requirements for the processes themselves. The results can be applied at the enterprises of the silk industry.

The main factor in growing high-quality crops is the rational use of mineral fertilizers, stimulants, and defoliants. It is worth noting that an agrotechnical event as defoliation plays an important role for the high-quality harvesting of raw cotton in a short time. In the presence of defoliants, cotton leaves effectively improve air circulation among the cotton rows, and in the forward direction, sunlight is detected and yield increase by 1.5- 2.0 c/ha due to accelerated ripening. In the following study, the mutual influence of the components in two water systems has been studied in a wide temperature and concentration range; the formation of a new phase of the compound (С6 Н5 O7 )2 Са3 ∙4H2 O, which is identified by chemical and physical-chemical methods of analysis has been established. The results of the studied systems show the possibility to obtain a liquid defoliant with physiological activity based on calcium chlorate and ammonium citrate, dimonoetanolamine citrate. The method of obtaining a new defoliant will be used in the chemical industry, as well as the obtained defoliants in agricultural cotton growing.

In the diagnosis and early detection of Glaucoma and diabetic retinopathy, when delicate vasculature grows in the retina, precise identification and localization of the border optic disc are highly significant. This research provides an automated method to localize and detect the optic disc. The proposed method uses the clustering methodology to locate the optic disc region. Fuzzy C Mean and Density Based Scan (DB Scan) clustering approach is evaluated on the publicly accessible DRIVE, diaretdb1, diaretdb0, and databases, which were created to aid comparative investigations on optic disc localization and detection in retinal images. With Diaretdb0 and Drive DB, the DB Scan clustering approach obtained an accuracy of 94.11% and 81.18%, respectively, which is better than the Fuzzy C mean, and it performs DB scan better for the DiaretDB1 dataset.
The role of fatty acids in disturbance of energy processes in the early placenta with cytomegalovirus infection
Authors: Dovzhikova I. V. , Ishutina N. A. , Andrievskaya I. A. , Dorofienko N. N.
Published: April 2023

Introduction. Cytomegalovirus (CMV) infection directly and indirectly can cause placental dysfunction. One of the reasons for its development may be a deficiency of energy supply due to changes in the level of fatty acids (FA) – the main sources of energy in the cell.

Aim. Analysis of the fatty acids concentration and causes of its changes in the placenta during exacerbation of CMV infection in the first trimester of pregnancy.

Materials and methods. Biosamples (venous blood, epithelium from the inner surface of the cheek, mucous membrane of the cervical canal, villous chorion) of 32 CMV-seropositive women with an exacerbation of CMV infection in the first trimester of pregnancy (main group) and 30 CMV-seronegative women (control group) were studied. Exacerbation of CMV infection was diagnosed by ELISA to detect IgM and IgG with avidity of 65% or more, PCR to detect CMV DNA. The profile and relative concentration of individual FA in villous chorion lipid extracts were studied by gas-liquid chromatography. The activity of pyruvate dehydrogenase, succinate dehydrogenase, NADP-dependent malate dehydrogenase, and glucose-6-phosphate dehydrogenase was determined by a histochemical method on sections of freshly frozen villous chorion tissues.

Results. In the main group placentas, the concentration of medium-chain saturated fatty acids was statistically significantly lower: capric by 50%, lauric by 51%, unsaturated myristoleic by 44%; long-chain unsaturated acids: palmitoleic, oleic, linoleic and α-linolenic fatty acids by 52%, 55%, 57% and 64%, respectively; of polyunsaturated fatty acids with a very long chain: eicosapentaenoic and docosahexaenoic by 44% and 41%, respectively. The activity of enzymes: succinate dehydrogenase, pyruvate dehydrogenase, NADP-dependent malate dehydrogenase and glucose-6-phosphate dehydrogenase decreased.

Conclusion. Thus, we found a decrease in energy supply in the placenta during exacerbation of chronic CMV infection in the first trimester of pregnancy. Disorders of placental energy metabolism can cause placental insufficiency, which has adverse consequences for fetal development.

Пестициды, изобретенные в первой половине ХХ-го века и широко внедренные в сельское хозяйство всех стран, производивших продукты питания, в послевоенный период существенно воздействуют как на окружающую среду, накапливаясь в воде и почве, так и передаваясь по пищевым цепям, концентрируясь в них, так и непосредственно на здоровье людей, поскольку они также потребляют продукты питания, произведенные с использованием пестицидов на загрязненной пестицидами почве. Почвенная микрофлора обусловливает плодородие почв и влияет в положительном смысле на условия вегетации растений, поэтому данная тема представляется нам актуальной в настоящее время. В последнее время все большее значение приобретают микробиологические способы очищения почв от различных пестицидов. Не менее актуальным является подбор пестицидов, способных быстро разрушаться в почве и существенно влиять на снижение загрязнения окружающей среды.

C’est le sujet d’actualité ultra présent sur tous les réseaux sociaux et dans la presse : ChatGPT. Si on analyse avec l’outil Google Trends la recherche sur le moteur de recherche de « ChatGPT » dans le monde, les résultats sont impressionnants. En effet, d’un point de vue méthodologie, l’outil Google Trends précise que « Les résultats reflètent la proportion de recherches portant sur un mot clé donné dans une région et pour une période spécifique, par rapport à la région où le taux d'utilisation de ce mot clé est le plus élevé (valeur de 100). Ainsi, une valeur de 50 signifie que le mot clé a été utilisé moitié moins souvent dans la région concernée, et une valeur de 0 signifie que les données pour ce mot clé sont insuffisantes ». Cet outil conversationnel basé sur une IA capable de générer du contenu écrit de qualité est très présent aussi dans les médias car il fascine autant qu’il effraie et qu’il suscite de polémiques (massification des plagiats, détournements à des fins malveillantes, sécurité et confidentialité des données, etc.).

Authors: Davis Molly
Published: April 2023

This report presents the results of vegetation monitoring efforts in 2022 at Scotts Bluff National Monument (SCBL) by the Northern Great Plains Inventory and Monitoring Network (NGPN) and Fire Ecology Program (NGPFire). NGPN began vegetation monitoring at SCBL in 2011, and this was the twelfth year of combined monitoring efforts between NGPN and NGPFire at SCBL. NGPN did not visit SCBL in 2020 or 2021 due to travel restrictions during the COVID-19 pandemic. However, NGPFire was able to do vegetation monitoring at SCBL during these two years. Crew members from NGPN visited eight long-term monitoring plots to collect data on the plant communities at SCBL. This work is part of a long-term monitoring effort designed to provide a better understanding of the condition of the vegetation community and how it changes over time. NGPN staff measured species richness, herb-layer height, native and non-native species abundance, ground cover, and site disturbance at each of the plots. In plots where woody species were present, tree regeneration, tall shrub density, tree density, and woody fuel loads were also measured. The NGPFire crew visited an additional seven plots in the Eagle Rock and North Platte burn units to better understand the effects of prescribed fire on vegetation. The NGPFire crew measured herb-layer height, native and non-native species abundance, ground cover, and site disturbance at each of the plots. The NGPFire crew conducted one prescribed fire in 2022, in the Eagle Rock burn unit, on April 25, 2022. In 2022, the monitoring crews identified 73 unique plant species in 15 monitoring plots. Of those species, 12 were exotic species. Two species considered rare in Nebraska were observed in the plots, including spotted fritillary, Fritillaria atropurpurea. At every plot except for two, the absolute cover of native species was greater than the absolute cover of exotic species. Monitoring crews collected tree regeneration data in three plots and found one species of seedling (chokecherry) and one species of adult tree (Rocky Mountain juniper). Ground disturbances, observed in fourteen of the fifteen plots, included animal use, prescribed fire, erosion, and soil disturbance
