Authors: Jondri Jondri , Indwiarti Indwiarti , Puspandari Dyas
Published: December 2023

Retweets are a way to spread information on Twitter. A tweet is affected by several features which determine whether a tweet will be retweeted or not. In this research, we discuss the features that influence the spread of a tweet. These features are user-based, time-based and content-based. User-based features are related to the user who tweeted, time-based features are related to when the tweet was uploaded, while content-based features are features related to the content of the tweet. The classifier used to predict whether a tweet will be retweeted is Multi Layer Perceptron (MLP) and MLP which is optimized by the swarm intelligence algorithm. In this research, data from Indonesian Twitter users with the hashtag FIFA U-20 was used. The results of this research show that the most influential feature in determining whether a tweet will be retweeted or not is the content-based feature. Furthermore, it was found that the MLP optimized with the swarm intelligence algorithm had better performance compared to the MLP.

„A najprzód Najwyższemu Stwórcy za wszystkie dobrodziejstwa składam dzięki...” Duchowieństwo eparchii przemyskiej wobec Boga i religii w świetle testamentów 1817–1827
Authors: Lecyk William
Published: December 2023

Artykuł odnosi się do religijności duchowieństwa greckokatolickiego z terenu eparchii przemyskiej. Analizę oparto na testamentach duchownych z lat 1817–1827 z zasobu Archiwum Państwowego w Przemyślu. Elementy religijne występują najczęściej w formie inwokacji dewocyjnej, krótkiej refleksji, będącej pozostałością staropolskiej arengi, w dyspozycjach pogrzebowych oraz w postaci motywu „sądu boskiego” i błogosławieństwa. Analiza wykazała, że wspomniane elementy nie są powszechne w badanych testamentach, a treść z reguły ograniczona. Autor stara się odpowiedzieć na pytanie, jakie są powody tego zjawiska oraz co analizowane testamenty przekazują na temat religijności tej grupy społecznej.

(Nie)męscy bohaterowie? Portret ojca i syna w "Pokorze" Szczepana Twardocha
Authors: Niesporek-Klanowska Katarzyna
Published: December 2023

Szkic jest próbą przyjrzenia się portretom dwóch, głównych bohaterów Pokory Szczepana Twardocha (2020). Przez opis doświadczeń Aloisa, czytelnik dobrze poznaje postać jego ojca – Antona, który ma destrukcyjny wpływ na życie syna i jest winien większości jego traum – ran dzieciństwa. Młody Pokora, wychowując się w patriarchalnym domu i społeczeństwie, przyzwyczaja się do hegemonii ojca, jego gniewu i przemocowych zachowań. Nauczony ponad wszystko pokory, idzie z nią dalej w świat i przenosi ją do swojego młodzieńczego i dorosłego życia, co objawia się m.in. w niemożności własnej obrony, w trudnych relacjach z kobietami, w problemach z tożsamością i męskością. Próba podjęcia przez Aloisa jakiejkolwiek zmiany w swoim życiu, kończy się zazwyczaj jego ponownym upadkiem i upokorzeniem.
„Prometeusz wasz polski”. O doświadczeniu wolności i niewoli w pismach Waleriana Łukasińskiego
Authors: Ziołowicz Agnieszka
Published: December 2023

Artykuł zawiera interpretację pism Waleriana Łukasińskiego, które powstały podczas jego pobytu w więzieniu w Szlisselburgu.  W centrum rozważań znajduje sie kluczowe dla autora doświadczenie wolności i niewoli. Jest ono rozpatrywane w kontekście biografii Łukasińskiego, dziewiętnastowiecznej literatury więziennej (Silvio Pellico), a także przez pryzmat ówczesnych losów polskiej zbiorowości i sposobów ich rozumienia (czasy napoleońskie, Kongres Wiedeński, funkcjonowanie Królestwa Polskiego, powstanie listopadowe, powstanie styczniowe, stosunki polsko-rosyjskie). Ważnym punktem odniesienia jest postrzeganie wolności w wieku XIX, zwłaszcza w dwóch aspektach: wolności politycznej (niepodległość narodowa, wolność społeczna, wolność obywatelska, wolność osobista) i wolności pozapolitycznej, wewnetrznej (przede wszystkim chrześcijańska wolność duchowa). W świetle przedstawionych analiz bohater artykułu okazuje się postacią o cechach prometejskich.

Published: December 2023

In this issue, our contributors share their thoughts, ideas, and doubts, describing how they and their library teams have worked hard during the recent crisis years to develop, improve, or find effective models of operation to prepare for high-level negative events and minimise catastrophic consequences. Knowledge management is definitely about university libraries, which have shifted their role from accessing and managing information to accessing, sharing and managing knowledge. The papers describe the library experience of knowledge management in times of crisis as a combination of information, communication and human resource management. The crisis experience is considered in the context of the conference "University Library at a new stage of social communications development" 2023 as the experience gained in the working library environment of universities around the world, created in the rapidly changing, chaotic and often dangerous for people's health and life conditions of large-scale crisis events. By illustrating the challenges, surprises, and rewards we face in library and information science in different countries, we hope that the articles in this issue will provide us all with the motivation to keep going in a difficult period. At the very least, these articles will help readers to appreciate how our understanding of higher education librarianship continues to evolve in times of crisis.
Applicability of Solution-Focused Brief Counseling in Turkish Culture: A Contextual Perspective
Authors: ÖZER İsa Özgür
Published: December 2023

This article focuses on the applicability of solution-oriented brief counseling in Turkish culture. To this end, I discuss the theoretical framework and therapeutic process of solution-focused counseling and the predispositions of counselors to provide solution-focused counseling from a contextual perspective. An important implication from this investigation is that traits such as authoritativeness, approval for power inequalities, and external locus of control may harm the applicability of this approach in Turkey. However, it is possible to say that the solution-oriented approach is compatible with the Turkish people in many ways. In this respect, solution-focused counselors may need different methods to work more harmoniously with Turkish clients. In conclusion, considering the cultural features of Turkish society, I make recommendations about what these methods might be and how solution-focused counseling adapted better.

Oral microbiome-driven virulence factors: A novel approach to pancreatic cancer diagnosis
Authors: Zeng Xuemin , Ren Dapeng , Liu Ran , Zhang Qiang , Yan Xiao , Yuan Xiao
Published: December 2023

Pancreatic ductal adenocarcinoma (PDAC) is a highly aggressive malignancy, often associated with a poor prognosis for patients. One of the major challenges in managing PDAC is the difficulty in early diagnosis, owing to the limited and invasive nature of current diagnostic methods. Recent studies have identified the oral microbiome as a potential source of non-invasive biomarkers for diseases, including PDAC. In this study, we focused on leveraging the differential expression of virulence factors (VFs) encoded by the oral microbiome to create a diagnostic tool for PDAC. We observed a higher alpha diversity in VF categories among PDAC patients compared to healthy controls. We then identified a panel of VF categories that were significantly upregulated in PDAC patients, these being associated with bacterial adherence, exoenzyme production, and nutritional/metabolic processes. Moreover, Streptococcus-derived VFs were notably enriched in PDAC patients. We developed a diagnostic model using random forest analysis based on the levels of these VFs. The model's diagnostic accuracy was evaluated using receiver operating characteristic (ROC) curve analysis, with an area under the curve (AUC) of 0.88, indicating high accuracy in differentiating PDAC patients from healthy controls. Our findings suggest that VFs encoded by the oral microbiome hold potential as diagnostic tools for PDAC, offering a non-invasive approach that could significantly enhance early detection and prognosis, ultimately leading to improved patient outcomes.

There are numerous parking supervision and random booking procedures that regulate parking operations. Travel time to the parking slot and walking time inside the terminus can still be dropped if the parker can book a precise parking spot instead of an arbitrary one. This is achieved by our proposal, called sPark which is an app-based parking method that includes indoor navigation facility i.e., an app for parking with indoor navigation facility. sPark’s sharing system will rapidly book the optimal parking slots for parkers and advise them on the best feasible entrances for practice. Also, parkers will find the briefest path to their target using our proposed app’s navigation technique, saving them a lot of time roaming to the building. Different parking methods like sPark (our proposed), non-directed and directed methods (existing) are designed and assessed. The designed and assessed simulation outcomes of sPark indicate an important decrease in the overall driving time by 30% to 60% as compared to the non-directed method which is an existing method. Additionally, the resource sharing module in our scheme i.e., an app for parking with indoor navigation facility called sPark has revealed a 9.99% decrease in driving time in comparison to directed methods (existing) that feature interior cruising and direction only.

The interaction of a liquid with the surrounding air produces unstable waves that disintegrate the liquid into droplets, which is known as liquid atomization. The common internal flow of a liquid atomization nozzle experiences a single-phase flow but might turn into a multiphase flow with the existence of cavitation. Cavitation in internal flow has gotten a lot of attention because of the positive and negative consequences it can have depending on the application. One such advantageous result is that cavitation has been used to promote the atomization of liquid jets by causing gas bubbles in the atmosphere to collapse. Most of the past research on cavitation has focused on the exit orifice’s constant cross-section area. The current study investigates the effect of throat location and geometry on cavitation characteristics. Filtered water was used as the simulation fluid. The high-speed shadowgraph technique was applied to record the images of the internal flow patterns. The placement of the throat was discovered to have a substantial impact on the status of the cavitation. Cavitation began at the inlet of the throat when the throat was placed at the uppermost part of the exit orifice. However, when the throat is placed in the middle of the exit orifice, the cavitation begins at the end of the throat. Four cavitation regimes were identified, namely developing, mixed, super and sudden expansion cavitation. Furthermore, it was found that the discharge coefficient depends on the cavitation’s state and length, except when the cavitation is in the supercavitation regime.

TN2.0 is a web application that adopt the yield-after-spillage (YAS) convention to identify the optimum rainwater tank size. It is found that for a house of size 86.86 m2, the optimum tank size is 2 m3 with water-saving and storage efficiency values of 51% and 63.2% respectively. Additionally, the performance of the optimum tank size of 2 m3 was further examined under different water demand. It was found that a 2 m3 tank was still able to save water up to 42.1% for a family of 10 persons. Meanwhile, the storage efficiency shows a little increment from 63.2% to 67.8%.

The problem of constructing a HIL simulation stand for researching a technological process using programmable logic controller (PLC) "Baget" is described in this article. Issues of modeling technological processes are currently extremely relevant, since modeling is a mandatory stage in the automated process control systems development. An adequate model of the technological process allows debugging and verification of automated process control system algorithms without using real equipment, reducing financial costs and the probability of emergency situations. The HIL modeling method involves partial use of real equipment as part of the model. The inclusion of standard components of the original object in the model does not require detailed mathematical model and at the same time provides a more complete correspondence to the original. Due to using a computer from the original object, the stand software operates under conditions close to the real technological process, which improves the quality of the simulation results. The HIL modeling stand includes the following components: control computer of automated process control system; programmable logic controller PLC "Baget"; simulation computer. The stand for the basic element of an automated process control system allows to speed up the process of prototyping and debugging even in the case of complex systems, because it will be easier to build the entire system from correctly functioning elements. Another advantage of this approach is that the stand is not tied to a specific type of technological process or to a narrow area of production — the stand allows the use of ready-made models, the development of new models, and the inclusion of various function libraries. The simplicity of the stand design with this approach is combined with a full range of functionality. By connecting additional software, you can create more complicated and detaild model. This stand is also capable of serving both for debugging PLC algorithms and as a simulator for maintenance personnel of a real control object, because the stand operator can simulate failures and errors of standard equipment, emergency situations at the control object. Using C and JavaScript programming languages for development ensures portability and ease of expanding the capabilities of the modeling software. The development of complex systems based on HIL modeling allows saving resources and effectively solving assigned problems, therefore the proposed approach to building stands will be in demand in the process of developing an automated process control system based on the PLC "Baget".

The article discusses the mechanism for updating the built-in software (firmware) in distributions of the Linux operating system (OS). Considering the import "substitution strategy" in Russia proposed in technology sector and the active transition to this OS, including in solutions related to the digitalization of the energy sector, the problem of additional control over the firmware update process, incl. in used domestic distributions (AstraLinux, AltLinux). At the moment most popular mechanism of automatic firmware update is Linux Vendor Firmware Service (LVFS), article includes brief description of its update process. Using software developed for complete monitoring LVFS metadata were found multiply inconsistencies of current scheme of firmware update — deleting of files from index, replacement of already uploaded images with same id. Also basing on client agent metadata it is possible to organize targeted substitution of binary images transferred by service directly to hardware bypassing built-in monitoring tools. Finally it is concluded that there are potential vulnerabilities in this mechanism and a solution is proposed in the form of organizing own service with additional layer for verification of "firmware" during process of its distribution. If scheme with additional security layer over base of popular and well proved by practice LVFS will be successful it can be used in industrial applications with including in future in appropriate standards as reference model.

A szociális robotok térnyerésével az emberekkel folytatott interakciók gördülékenyebbé tétele kulcsfontosságúvá válik. Az emberi kommunikáció fontos aspektusa az érzelmek, mint belső állapotok viselkedésben megjelenő kifejezése, melyek felismerése, és mesterségesen generált, helyzetnek megfelelő érzelemkifejezések mutatása a robotok számára is nagy jelentőséggel bír. Az emberi érzelmek kutatása, definiálása és modellezése a pszichológia, etológia és más kapcsolódó diszciplínák területéről kilépve a robotikával fonódik össze. Jelen cikkünkben az ember-robot interakciós kutatásokban használt elterjedt érzelemfelismerési és -kifejezési módszereket, illetve ezek szakirodalmi hátterét foglaljuk össze.

В статье представлены результаты технологического и функционального анализа костяных пронизок ранней стадии верхнего палеолита из слоя 11 в центральном зале Денисовой пещеры, расположенной на северо-западе Алтая. Эти изделия являются одной из наиболее массовых категорий украшений начала верхнего палеолита в материалах пещеры. Реконструирована технологическая последовательность производства бусин-пронизок, включавшая несколько стадий — подбор заготовки, обработку строганием, изготовление преформы способом усечения эпифизов, нанесение на преформу орнамента, нанесение разметки для разделения преформы на короткие трубочки, ее деление с помощью пиления или резания, фрагментацию по надрезам, удаление губчатого вещества и выравнивание мест надрезов. С учетом отсутствия заготовок и диагностичных отходов производства в технологическом контексте комплекса высказано предположение об изготовлении цилиндрических бусин за пределами изученного участка центрального зала пещеры. На основе трасологического анализа на украшениях выявлены следы износа, вызванного контактом предметов с одеждой или кожей человека, а также их крепления на нитке или тонком ремешке. Пронизки широко использовались верхнепалеолитическими обитателями пещеры в качестве элементов украшения одежды, личных нательных ожерелий и, вероятно, браслетов. Установлено, что наибольшее сходство алтайские бусины-пронизки имеют с ориньякскими изделиями из близких по возрасту, но территориально значительно удаленных комплексов Западной, Центральной и Восточной Европы.

На ранненеолитическом памятнике Ракушечный Яр (Нижнее Подонье) были найдены свидетельства последовательного заселения прибрежной зоны в VI тыс. до н.э. Анализ фаунистических остатков, специфический орудийный набор, ограниченные технологические контексты позволили сделать заключение о сезонном узконаправленном характере стоянки на ранних этапах ее существования. В статье представлены результаты изучения костяных изделий из слоев 23-11 раскопа I на памятнике Ракушечный Яр и определено их место в контексте костяных индустрий синхронных археологических культур. Для коллекции характерно доминирование острий. Несмотря на разнообразие их морфологии, отмечается схожесть в видах использованных заготовок и методах изготовления. Кроме острий представлены два роговых шпателеобразных орудия и два изделия со скошенным краем из рога благородного оленя и кости. Ограниченный типологический и функциональный набор подчеркивает специфику хозяйственной деятельности на данном поселении, которой он и был во многом обусловлен. Трасологический анализ позволил выделить устойчивые серии орудий для работы с кожей, грубыми растительными материалами (возможно, для плетения корзин). Шпателеобразные изделия, скорее всего, использовались для работы по минеральным материалам, например, для обработки поверхности сосудов. Некоторые общие аналогии данной костяной индустрии могут быть прослежены в комплексах Северного Прикаспия и Нижнего Поволжья. Наиболее близкие типологические и технологические аналогии обнаруживаются в материалах закавказского неолита (Араташен-Шулавери-Шомутепе), традиции которого могли быть унаследованы от культур Леванта и Загроса.
