körében
Authors: Kéri Anita
Published: October 2023

A felsőoktatási marketing az elmúlt években széles körben kutatott
területté vált. A fokozódó verseny miatt kulcsfontosságú, hogy hatékony
marketingeszközökkel célozzák meg a külföldi hallgatókat a felsőoktatási
intézmények. Az online marketing eszközök központi szerepet játszanak a
külföldi hallgatók bevonzásában, megtartásában és igényeinek
kielégítésében. Jelen szakirodalmi áttekintés célja, hogy feltárja, hogyan
jelenik meg a vizuális észlelés az online marketingben és azon belül is a
felsőoktatási szektorban, különös tekintettel az intézmények
közösségi-média, valamint honlap felületeire. A kutatás abban az értelemben
újszerű, hogy a felsőoktatási marketing területén marketinggel, valamint a
hallgatók vizuális észlelésével kapcsolatos kutatások elenyészők, így jelen
szakirodalmi feltárás betekintést nyújt a külföldi hallgatók online
felsőoktatási marketingjének megítélésébe.
Fenntarthatóság oktatása hackathon módszertannal
Authors: Putzer Petra
Published: October 2023

A hackathon mint módszertan rendkívül intenzív kurzusélményt tesz
lehetővé, folyamatos munka és gyakorlati központú szemlélet vonzó terméket
jelent a hallgatók számára, akik probléma-megoldó, kommunikációs és
csoportmunkához kapcsolódó készségeiket és képességeiket is fejleszthetik.
Mindennek alapja pedig miért ne lehetne akár a fenntarthatóság. A tanulmány
azt vizsgálja, hogy mérhető-e fejlődés a hallgatók fenntarthatósággal
kapcsolatos tudásában és az ahhoz való hozzáállásában, s ily módon arra
keresi a választ, hogy a hackathon megfelelő oktatási módszertant
jelenthet-e a fenntarthatóság témakör oktatása esetében. Ez utóbbi a
hackathon során alkalmazott nemzetközi Sulitest lekérdezésen keresztül
kerül mérésére, amelyet a Sulitest Association nonprofit szervezet gondoz.
A teszt két alkalommal mér (pre és post) elsősorban a tudást elemeket méri
kiegészítve attitűd állításokkal. A tesztek eredményei alapján a hackathon
önmagában nem feltétlenül hatékony módszer a fenntarthatósággal kapcsolatos
ismeretek bővítésére, viszont fontos szerepe van az attitűdformálásban és
az egyéni szerepvállalás fontosságának felismerésében, amely aztán a
rendszerszintű változáshoz vezethet. Az eredmények alapján a hackathonok
szerepe elsősorban a saját szerep tudatosítása, a rendszerben és a
rendszerszintű változásban való gondolkozás elősegítése lehet a
fenntarthatóság kapcsán.
Miniaturisation of the

Daphnia magna immobilisation assay for the reliabletesting of low volume samples
Authors: Küster Eberhard , Addo George Gyan , Aulhorn Silke , Kühnel Dana
Published: October 2023

International standard test guidelines for the ecotoxicological characterisation of various substances use organisms like algae, daphnids and fish embryos. These guidelines use relatively high volumes of water for the process of testing. However, for various samples such as extracts from environmental monitoring or leachates from microplastic aging experiments, the amount of available sample volume is limited. Using the exposure volumes as recommended in test guidelines would not allow to test a range of different concentrations or to repeat tests. Lower media volumes would allow the testing of more samples (more concentrations per sample, more test repetitions for statistical robustness) but it may also decrease the possible number of organisms tested in the same volume. Here, we aimed at reducing the test volumes in the acute daphnia assay without impacting animals’ sensitivity towards toxicants. A literature review on existing miniaturisation approaches was used as a starting point. Subsequently, assays employing conventional as well as reduced test volumes were compared for 15 selected test substances with a diverse spectrum of lipophilicity. Results showed that there are differences in EC
50 between the two approaches, but that these differences were overall only within a range of a factor of two to three. Further, by retrieving EC50 values for the genus Daphnia and 15 test substances from the US EPA database, we demonstrated that our results are well inline with the general differences in sensitivities.
Voces de la niñez sobre violencia del narcotráfico en Morelos, México
Authors: González-Arellano Margarita , Ruíz-Sánchez Joel
Published: October 2023

Este artículo presenta los resultados del análisis a una muestra de 47 dibujos y 43 relatos producidos por niños y niñas en contextos de violencia del narcotráfico para conocer qué experiencias y saberes configuran cotidianamente, lo anterior desde un marco de complejidad de las violencias, de reconocimiento de la niñez como sujetos sociales, donde se recurre al dibujo y al relato como dispositivos de enunciación y visualidad. Se entrevistaron a 14 participantes, de 7 a 12 años, quienes testimoniaron sobre espacios significativos, sus miedos y el futuro. La información fue procesada mediante un análisis relacional de frases-imágenes y sistematizada en una cartografía testimonial. Los hallazgos muestran que los participantes enfrentaron balaceras y asesinatos de familiares, amigos, vecinos; tienen miedo a ser secuestrados e imaginan un futuro esperanzador. Se concluye que la violencia del narcotráfico afecta significativamente sus espacios cotidianos, íntimos y sociales, y los vínculos afectivos que establecen en sus relaciones intersubjetivas.

Tujerodni invazivni hrošč semenar Megabruchidius dorsalis (Chrysomelidae) živi v Sloveniji
Authors: Horvat Eva , Šajna Nina
Published: October 2023

The Asian seed beetle Megabruchidius dorsalis, which develops inside the seeds of native Gleditsia species, was first recorded in Europe in Italy in 1989. In Slovenia, it was first recorded in Maribor in 2017. Its presence was confirmed in 15 other European countries. In the new range, the seed beetle switched to two new hosts from North America, the honey locust (Gleditsia triacanthos) and the Kentucky coffeetree (Gymnocladus dioicus) both related to the Asian Gleditsia species. Mature G. triacanthos and Gy. dioicus seed pods were collected from the ground at locations in the central and the northeastern parts of Slovenia to investigate the presence of M. dorsalis outside the first described locations in Maribor. Seed pods were kept in bags under constant conditions in laboratory. Exit holes of seed pods and seeds typical of M. dorsalis were found at 36 locations (97%), while alive or dead M. dorsalis beetles were recorded at 26 locations (70%).

Overlooked and Invisible: A Profile of the Japanese Educated Working Poor
Authors: Stiefenhofer Pascal
Published: October 2023

Expanding the work proposed by Murakami et al. (2011), we seek to discover and profile a subset of the Japanese working poor, namely those who are educated to degree level. Using data from the Japanese Household Panel Survey, we build up a profile into the educated working poor, and show they have significantly lower self-reported levels of income satisfaction and life satisfaction. Further, we explore the extent to which geographical factors play a key role in explaining the newly identified educated working poor, and find that there are significant spatial differences in the poor rate, and that job location, occupation, and firm size is significantly different for the educated working poor compared to the working poor.
The fibroblast growth factor–Klotho axis at molecular level
Authors: Sun Fuqiang , Liang Panpan , Wang Bo , Liu Wenbo
Published: October 2023

Klotho is a recently discovered protein that has positive effects on all systems of the body, for example, regulating calcium and phosphorus metabolism, protecting nerves, delaying aging and so on. Fibroblast growth factors (FGFs) are a group of polypeptides that function throughout the body by binding with cell surface FGF receptors (FGFRs). Endocrine FGFs require Klotho as a co-receptor for FGFRs. There is increasing evidence that Klotho participates in calcium and phosphorus regulation and metabolic regulation via the FGF–Klotho axis. Moreover, soluble Klotho can function as a separate hormone to regulate homeostasis on various ion channels and carrier channels on the cell surface. This review mainly explains the molecular basis of the membrane signaling mechanism of Klotho.

Objectives

Numerous studies have proven the potential of cytokeratin 19 fragment 21-1 (CYFRA 21-1) detection in the (early) diagnosis and treatment monitoring of non-small cell lung cancer (NSCLC). Conventional immunoassays for CYFRA 21-1 quantification are however prone to interferences and lack diagnostic sensitivity and standardization. Liquid chromatography-tandem mass spectrometry (LC-MS/MS) is an emerging approach based on a different, often superior, detection principle, which may improve the clinical applicability of CYFRA 21-1 in cancer diagnostics. Therefore, we developed and validated a protein precipitation, immunoaffinity (IA) LC-MS/MS assay for quantitative analysis of serum CYFRA 21-1.

Methods

Selective sample preparation was performed using ammonium sulfate (AS) precipitation, IA purification, tryptic digestion and LC-MS/MS quantification using a signature peptide and isotopically labeled internal standard. The workflow was optimized and validated according to EMA guidelines and results were compared to a conventional immunoassay.

Results

Significant interference effects were seen during IA purification, which were sufficiently solved by performing AS precipitation prior to IA purification. A linear calibration curve was obtained in the range of 1.0–100 ng/mL (R2=0.98). Accuracy and precision were well within acceptance criteria. In sera of patients suspected of lung cancer, the method showed good correlation with the immunoassay.

Conclusions

A robust AS precipitation-IA LC-MS/MS assay for the quantification of serum CYFRA 21-1 was developed. With this assay, the clinically added value of LC-MS/MS-based detection over immunoassays can be further explored.
Study on discrete degenerate Bell distributions with two parameters
Authors: Kim Taekyun , Kim Dae San , Kim Hye Kyung
Published: October 2023

Recently, Freud and Rodriguez proposed a new counting process which is called the Bell–Touchard process and based on the Bell–Touchard probability distribution. This process was developed to solve the problem of rare events hypothesis which is one of the limitations of the Poisson process. In this paper, we consider the discrete degenerate Bell distributions and the degenerate Bell process which are “degenerate versions” of the Bell–Touchard probability distributions and the Bell–Touchard process, respectively. We investigate several properties of the degenerate Bell distribution. We introduce the degenerate Bell process by giving two equivalent definitions and show one method of constructing a new infinite family of degenerate Bell process out of a given infinite family of degenerate Bell process.
Cathepsin L-mediated EGFR cleavage affects intracellular signalling pathways in cancer

Published: October 2023

Proteolytic activity in the tumour microenvironment is an important factor in cancer development since it can also affect intracellular signalling pathways via positive feedback loops that result in either increased tumour growth or resistance to anticancer mechanisms. In this study, we demonstrated extracellular cathepsin L-mediated cleavage of epidermal growth factor receptor (EGFR) and identified the cleavage site in the extracellular domain after R224. To further evaluate the relevance of this cleavage, we cloned and expressed a truncated version of EGFR, starting at G225, in HeLa cells. We confirmed the constitutive activation of the truncated protein in the absence of ligand binding and determined possible changes in intracellular signalling. Furthermore, we determined the effect of truncated EGFR protein expression on HeLa cell viability and response to the EGFR inhibitors, tyrosine kinase inhibitor (TKI) erlotinib and monoclonal antibody (mAb) cetuximab. Our data reveal the nuclear localization and phosphorylation of EGFR and signal trancducer and activator of transcription 3 (STAT3) in cells that express the truncated EGFR protein and suggest that these phenomena cause resistance to EGFR inhibitors.
Introducing VR personas: an immersive and easy-to-use tool for understanding users
Authors: Maruhn Philipp , Prasch Lorenz , Gerhardinger Florian , Häfner Sophia
Published: October 2023

Personas have been established as an indispensable tool in software and product development. They continuously accompany the development process and seek to build empathy and establish an emotional relationship between developers and users. However, this does not always succeed, with the reasons for failure often lying in the personas themselves. If they do not have a sufficient level of detail or do not reflect everyday people, they lose credibility and therefore their purpose of representing the user. Poor communication of personas is another reason they are quickly forgotten. In this paper, we present a new approach to experiencing personas beyond traditional means such as posters or slides. With the help of virtual reality, we create immersive, three-dimensional personas that can be visited in their own living room. The basis of the implementation is a comprehensive dataset, containing aggregated data from over 8000 detailed face-to-face interviews. We base the layout of the apartment, the furniture, and the characters themselves on the archetypal characteristics of their corresponding user group. In the future, we plan to validate whether this approach can be successful in creating a deeper and more sustainable connection between personas and developers and designers.
Melting mechanisms in corotating twin-screw extrusion: a critical review
Authors: Vergnes Bruno
Published: October 2023

Corotating twin-screw extrusion is widely used for many applications in mixing and compounding. While the flow conditions in the different screw elements are now well known and accurately modeled, the melting mechanisms, i.e. the transition between solid and molten polymer, are much less understood and are still the subject of debates. In this review paper, experimental observations from the literature are first presented and commented, followed by the proposed theoretical approaches. It will be concluded that a satisfactory model considering the different mechanisms involved in the melting step has yet to be elaborated, unlike what exists for the single screw extrusion.
Simplified REGINN-IT method in Banach spaces for nonlinear ill-posed operator equations
Authors: Mahale Pallavi , Shaikh Farheen M.
Published: October 2023

In 2021, Z. Fu, Y. Chen and B. Han introduced an inexact Newton regularization (REGINN-IT) using an idea involving the non-stationary iterated Tikhonov regularization scheme for solving nonlinear ill-posed operator equations.
In this paper, we suggest a simplified version of the REGINN-IT scheme by using the Bregman distance, duality mapping and a suitable parameter choice strategy to produce an approximate solution.
The method is comprised of inner and outer iteration steps.
The outer iterates are stopped by a Morozov-type stopping rule, while the inner iterate is executed by making use of the non-stationary iterated Tikhonov scheme.
We have studied convergence of the proposed method under some standard assumptions and utilizing tools from convex analysis.
The novelty of the method is that it requires computation of the Fréchet derivative only at an initial guess of an exact solution and hence can be identified as more efficient compared to the method given by Z. Fu, Y. Chen and B. Han.
Further, in the last section of the paper, we discuss test examples to inspect the proficiency of the method.
All-dielectric metaoptics for the compact generation of double-ring perfect vector beams
Authors: Vogliardi Andrea , Ruffato Gianluca , Bonaldo Daniele , Dal Zilio Simone , Romanato Filippo
Published: October 2023

Perfect vortices, whose ring profile is independent of the topological charge, play a key role in telecommunications and particle micro-manipulation. In this work, we report the compact generation of a new kind of double-ring perfect vortices, called double-ring perfect vector beams, by exploiting dual-functional silicon metaoptics. In particular, we develop and test a new paradigm to generate those beams with the possibility of selecting different topological charges between the two rings. The generated beams are characterized through a filtering method, proving that the two rings have a vectorial nature with the same magnitude and either the same or different topological charges. Their unique properties suggest promising applications for optical tweezing and manipulation of low refractive-index particles, trapping of cold atoms, and high-capacity communications.
Mathematical analysis of the transmission dynamics of viral infection with effective control policies via fractional derivative

Published: October 2023

It is well known that viral infections have a high impact on public health in multiple ways, including disease burden, outbreaks and pandemic, economic consequences, emergency response, strain on healthcare systems, psychological and social effects, and the importance of vaccination. Mathematical models of viral infections help policymakers and researchers to understand how diseases can spread, predict the potential impact of interventions, and make informed decisions to control and manage outbreaks. In this work, we formulate a mathematical model for the transmission dynamics of COVID-19 in the framework of a fractional derivative. For the analysis of the recommended model, the fundamental concepts and results are presented. For the validity of the model, we have proven that the solutions of the recommended model are positive and bounded. The qualitative and quantitative analyses of the proposed dynamics have been carried out in this research work. To ensure the existence and uniqueness of the proposed COVID-19 dynamics, we employ fixed-point theorems such as Schaefer and Banach. In addition to this, we establish stability results for the system of COVID-19 infection through mathematical skills. To assess the influence of input parameters on the proposed dynamics of the infection, we analyzed the solution pathways using the Laplace Adomian decomposition approach. Moreover, we performed different simulations to conceptualize the role of input parameters on the dynamics of the infection. These simulations provide visualizations of key factors and aid public health officials in implementing effective measures to control the spread of the virus.

Published: October 2023

In this work, Raphanus caudatus (radish pod) leaves biomass was used as an adsorbent for the removal of crystal violet (CV) and Rhodamine B (RhB) dye from water medium. Adsorption process was performed by changing different adsorption factors such as adsorbent dose, agitation time, adsorbate concentration, pH and temperature to get maximum removal of dyes. It was observed that R. caudatus leaves biomass showed 48.7 and 19.0 mg/g value of adsorption capacity for CV and RhB dyes, respectively. High adsorption capacity value for CV was observed due to its less complex structure and small sized molecules as compared to the RhB dye molecules. Dyes removal process followed pseudo second order with the values of regression factor (R
2) found as 0.999 and 0.998 for CV and RhB, respectively. Values of R
2 were found as 0.999 and 0.998 for the removal of CV and RhB respectively while following the Langmuir adsorption isotherm model. It illustrates the single layered dye molecules adsorption over the homogeneous surface of the adsorbent. Value of enthalpy (ΔH°) was found as 11.983 and 12.28 kJ/mol for CV and RhB, respectively. It indicates endothermic nature of the process along with the increased entropy at the surface of the adsorbent during the process. Increase of salt concentration in adsorption medium caused the decreased percentage removal of dyes. Reported adsorbent also showed potential for the removal of toxic dyes from industrial wastewater.

A minőségi oktatás nélkülözhetetlen a társadalmi fejlődéshez
Authors: Farkas Éva
Published: October 2023

Az oktatás színvonala döntő hatással van az egész társadalom minőségére és kutatások széles köre bizonyítja, hogy az oktatás minősége ok-okozati összefüggésben áll a gazdasági és társadalmi fejlődéssel. A magasabb végzettségi és műveltségi szint nem csak a jobb foglalkoztatottsági és jövedelmi viszonyokkal mutat szoros összefüggést, de pozitív hatással van a várható élettartamra, az egészségi állapotra, az életminőségre és a szubjektív jóllétre, valamint csökkenti a szegénység és a társadalmi leszakadás kockázatát. Az oktatásba való befektetés tehát az oktatáson kívüli szakpolitikai területek céljainak hatékonyabb megvalósítása szempontjából is előnyökkel jár.

Miközben a legnagyobb kihívást az emberek továbbképzése és felzárkóztatása jelenti a gyorsan változó munkaköri készségigényekhez, azzal a ténnyel is szembesülni kell, hogy a felnőttek jelentős része súlyos alapkompetenciahiánnyal küzd, ami nemcsak a foglalkoztathatóságukat korlátozza, hanem az információkhoz és a tanuláshoz való hozzáférésüket, és a mindennapi életük hatékony menedzselésének képességét is. A halmozódó kihívásokra leghatékonyabban az oktatás minőségének növelésével lehet válaszolni.

A tanulmány a képzettség és az egyéni, társadalmi, és munkaerő-piaci boldogulás közötti összefüggések elemzésével igyekszik felhívni a figyelmet a tanulás és a minőségi oktatás jelentőségére, illetve annak egyre nyilvánvalóbb hiányára.
Ahol zsarnokság van – Illyés Gyula: Kegyenc (1963)
Authors: N. Horváth Béla
Published: October 2023

Az itt közlendő tanulmány az Illyés Gyula életművét bemutató (készülő) nagymonográfia egyik rövid részlete. Illyés az „új fogalmú hazafiság” bemutatásának szándékával az ötvenes években több darabot írt. Ezek a kor „forradalmi romantikájának” jegyében keletkeztek, s művészi gyengeségeik a politikai kényszereknek is tulajdoníthatók. A hatvanas évek eleji darabok a hatalom moralitásának/immoralitásának kérdéseit taglalják. Elsősorban a Kegyenc. A szöveg nem a legsikerültebb Illyés-mű, de kisebb dramaturgiai hiányosságai ellenére is pontosan és hűen adja vissza a zsarnokság mindent behálózó, az embert személyes létében is tönkretevő rendszerét, természetét. Illeszkedik az életmű ember és a hatalom kérdéseiről szóló emblematikus szövegeihez.
A tanulóközpontú iskola, a kompetenciák fejlesztése és a játékos, tapasztalati matematikatanulás: elméleti megalapozás
Authors: Klein Sándor , Kiss Julianna , Nemeskéri Zsolt , Zádori Iván
Published: October 2023

A Pécsi Tudományegyetem munkatársaiként évtizedek óta törekszünk arra, hogy a tanárok minél sikeresebben járuljanak hozzá tanulóik legfontosabb kompetenciáinak fejlesztéséhez. Dolgozatunkban három olyan témát emeltünk ki (egy-egy neves pszichológushoz kapcsolódóan), amelyekkel a jövőben is intenzíven foglalkozni szeretnénk:

A személyközpontú megközelítés Carl Rogers munkássága alapján az elmúlt hatvan évben világszerte befolyásolja a segítő foglalkozásúak szemléletmódját. A 80-as években a szegedi Juhász Gyula Tanárképző Főiskoláról indulva kezdtünk hozzá elterjesztéséhez, amit a pécsi tanárok továbbképzésével folytattunk. 

John Raven pszichokibernetikai szemlélete arra mutat rá, hogy a pedagógia olyan komplex rendszer, amelyben a bonyolult kölcsönhatások miatt egy-egy tényező pozitív változása akár káros is lehet az összteljesítményre. Az egyetem, amikor díszdoktorrá avatta John Ravent, azt is ki akarta ezzel fejezni, hogy fokozottan építeni akarunk munkásságára a tanárképzésben. 

Dienes Zoltán Pál a játékos, tapasztalati, felfedező matematikatanulás/ matematika-tanítás világszerte legizgalmasabbnak tartott alakja. Életének utolsó éveiben ő is egyetemünk díszdoktora lett, és mi felvállaltuk, hogy játékos taneszközeit eljuttattjuk a magyar iskolákba. A „Dienes módszer” – reményeink szerint – mindenkivel megkedvelteti ezt a ma még sok diák számára idegen, szorongáskeltő tantárgyat.

A tanulmányban bemutatott irányzatok további komoly erőfeszítések esetén elősegíthetik, hogy pedagógiai gyakorlatunk gyerekközpontúbb és egyben eredményesebb legyen.

Park Un's ‘philosophy of self-cultivation’: Focusing on the System of Thought in 'Gyukmongpyeon'
Authors:   Institute of Korean Cultural Studies Yeungnam University, Song Hoyoung
Published: October 2023

This article examines the system of thought concerning Park Un's philosophy of self-cultivation, based on one of his two main works, Gyukmongpyeon.
Park Un was a representative scholar of Neo-Confucianism from the Gyeongbuk Seonsan region during the middle period of the Joseon Dynasty. He gained widespread recognition for his filial devotion to his parents. He studied under Park Young along with the Kim brothers, Kim Chwiseong and Kim Chwimun, contributing to the nationwide prominence of the Songdang school of thought. However, following the last wishes of his father, Park Jongwon, who had witnessed the tyrannical rule of King Yeonsan and the political chaos during King Jungjong's reign, he did not pursue a career in government. Instead, he stayed in his hometown, dedicated himself to scholarly pursuits, and worked to pass down his academic achievements to future generations. He also gained fame as a great scholar of his time through interactions and academic discussions with contemporary scholars like Lee Eonjeok and Lee Hwang.
At the age of 50 (in 1542), Park Un compiled Gyukmongpyeon by selecting various sayings from the Cheng-Zhu school of Confucianism centered around Cheng Yi and Zhu Xi, focusing on ‘Geo Gyeong Gung Ri’. ‘Geo Gyeong’ refers to a self-cultivation method that targets the heart-mind to foster virtue, while ‘Gung Ri’ refers to a study method targeting principles to explore all things and expand knowledge. These two elements collectively indicate the self-cultivation philosophy of the Cheng-Zhu school that needs to be integrated to prevent the human mind from falling into desire.
Lee Yulgok wrote in the postscript of Gyukmongpyeon: “Only after reading Master Park Un's Gyukmongpyeon did I realize how deep his research into the self-cultivation theory of the Cheng-Zhu school was, and how diligently he had studied. Had that not been the case, the sentences he selected could not have been so precise and heartfelt.
Although we can't meet t he v arious masters o f the C heng-Zhu s chool today, Park Un has gathered all their beneficial teachings left for future generations. The grace he has bestowed upon future scholars is indeed immense.” Through compiling Gyukmongpyeon, Park Un not only succinctly and clearly organized the self-cultivation philosophy of previous sages but also significantly contributed to the scholarly activities of future generations.
A Study on the Cause of Individualization in Korean Society: Focusing on the Division of Labor of E. Durkheim and K. Marx
Authors:   Institute of Korean Cultural Studies Yeungnam University, Ahn Do Hun
Published: October 2023

In this study, I tried to identify the cause of the post-social individualization phenomenon in Korean society, focusing on the theory of the division of labor of E. Durkheim and K. Marx. The results of the study are as follows. First, The interdependence of the division of labor creates social solidarity. According to E. Durkheim, the interdependent nature of the division of labor is strengthened by its development, creating social solidarity. Second, The relationship between division of labor and interdependence is not inevitable. This is because, as K. Marx pointed out, the division of labor can also create completely unequal dependencies. Third, The weakening or extinction of the interdependence of the division of labor leads to the phenomenon of post-social individualization. In a situation where the interdependence of division of labor has disappeared or weakened and the possibility of social solidarity is slim, people have no choice but to find their own way to live. The phenomenon of post-social individualization in Korean society came about in this way.

Published: October 2023

From the time the ‘Local Autonomy System’ began in earnest to today, each local government has made various efforts to create unique local cultural contents and spread positive local culture. This is not irrelevant to the perception that not only the local economy should be revitalized, but also the local people themselves should improve their living conditions and lifestyles, become subjects, organically relate to local life, and form a cultural identity of the region. However, even considering the modifier of region, local cultural contents that do not meet the needs of local residents and visitors will be shunned. Therefore, local governments need to establish the direction of local culture and local cultural content, continue to discover and utilize local cultural resources, and make efforts to preserve them.
Therefore, researchers want to develop a unique point of “value life” in the history of the Korean Catholic Church to explore sustainable use of the religious a nd c ultural heritage of t he C atholic Andong Diocese, called the “Duratbaemi Diocese”, and propose the planning direction of the content.
This study is of academic and social value in that it is the first study to deal with the content of the religious and cultural heritage of the Catholic Diocese of Andong, which has not been discussed so far.

Embryogenesis is highly dependent on maternally loaded materials, particularly those used for energy production. Different environmental conditions and genetic backgrounds shape embryogenesis. The robustness of embryogenesis in response to extrinsic and intrinsic changes remains incompletely understood. By analyzing the levels of two major nutrients, glycogen and neutral lipids, we discovered stage‐dependent usage of these two nutrients along with mitochondrial morphology changes during Caenorhabditis elegans embryogenesis. ATGL, the rate‐limiting lipase in cellular lipolysis, is expressed and required in the hypodermis to regulate mitochondrial function and support embryogenesis. The embryonic lethality of atgl‐1 mutants can be suppressed by reducing sinh‐1/age‐1‐akt signaling, likely through modulating glucose metabolism to maintain sustainable glucose consumption. The embryonic lethality of atgl‐1(xd314) is also affected by parental nutrition. Parental glucose and oleic acid supplements promote glycogen storage in atgl‐1(xd314) embryos to compensate for the impaired lipolysis. The rescue by parental vitamin B12 supplement is likely through enhancing mitochondrial function in atgl‐1 mutants. These findings reveal that metabolic plasticity contributes to the robustness of C. elegans embryogenesis.

Published: October 2023

This paper generalizes Razumikhin-type theorem and Krasovskii stability theorem of impulsive stochastic delay systems. By proposing uniformly stable function (USF) in the form of impulse as a new tool, some properties about USF and some novel pth moment decay theorems are derived. Based on these new theorems, the stability theorems of impulsive stochastic linear delay system are acquired via the Razumikhin method and the Krasovskii method. The obtained results enhance the elasticity of the impulsive gain by comparing the previous results. Finally, numerical examples are given to demonstrate the effectiveness of theoretical results.

Authors: Našlėnaitė Eberhardt Vaida
Published: October 2023

This article exposes some linguodidactic issues concerning teaching Lithuanian as a foreign language. Before discussing the study of multilingual students in section 3, the following theoretical premises are examined in sections 1 and 2: intercomprehension, language and multilingual awareness, L3 acquisition, experience with CLIL. The recordings of dialogues with the multilingual students show them to be aware language learners with a very specific and diverse theoretical motivation. One informant used a very traditional and grammar-oriented method for learning several languages. The main task for the teacher was to suggest a universal common learning plan and methods for the multilingual group in order to achieve the next language proficiency level and to improve students’ missingskills in language comprehension and speaking.
Substrate Specificity of Bacillus megaterium UСM B-5710 Keratinase
Authors: Avdiyuk K.V. , Varbanets L.D.
Published: October 2023

The specifics of the processing of livestock and poultry products is that in the process of obtaining the main marketable products, about half the feedstock at various stages of the technological process turns into waste that pollutes the environment. These by-products contain large amounts of the hard-to-digest keratin protein. The use of specific enzymes capable of degrading this protein helps not only to reduce the negative anthropogenic impact on nature but also to obtain valuable hydrolysates that can be used as a fertilizer for plants or a feed additive. The aim of this work was to study the ability of Bacillus megaterium UCM B-5710 to split various keratin-containing substrates: black and white chicken feathers, white turkey feathers, parrot feathers of various colors, sheep wool, pig bristles, and baby hair and nails. Methods. The culture was grown under conditions of submerged cultivation at 40 °C, with a nutrient medium stirring rate of 201 rpm for 6 days. For growth, a basic nutrient medium containing 0.5% defatted chicken feathers or other keratin-containing substrates as sole sources of carbon and nitrogen were used. Keratinase activity was assessed by UV absorption at 280 nm of hydrolysis products of keratin-containing raw materials. Protein was determined by the Lowry method, caseinolytic (total proteolytic) activity was determined by the Anson method modified by Petrova, and amino acid content was determined by the ninhydrin method. The degree of hydrolysis of the substrates was evaluated by the ratio of the initial and final weight of the substrate. Results. It was shown that the synthesis of keratinase by the culture of B. megaterium UCM B-5710 begins from the 6th hour of cultivation. The level of protein and proteolytic activity and the content of amino acids increased throughout the entire period of culture growth. The supernatant of the culture liquid of B. megaterium UCM B-5710 was most effective in splitting white chicken’s and turkey’s feathers, a little slower — feathers of black chicken and blue parrots, as well as wool of white sheep. According to the degree of splitting, the substrates used can be arranged in the following order: white turkey feathers > white chicken feathers > black chicken feathers > blue parrot feathers > white sheep wool > baby nails > pig bristle > baby hair. The study of the effect of feather color on the resistance to decomposition showed that black, blue, and red feathers are more resistant, which coincides with the literature data. Conclusions. B. megaterium UCM B-5710 produces keratinase capable of splitting both α- and β-keratins, however, with different efficiencies and rates.
Filipenses 2,5-11

Não há dúvidas de que ao cristão foi outorgado o dever de apresentar ao mundo o porquê do cristianismo ser a Revelação de Deus. Entretanto, nos últimos anos, na tentativa de estabelecer um discurso narrativo consubstanciado, a apologética cristã parece ter ficado presa dentro de estruturas argumentativas extremamente racionalistas. Se por um lado, esse esforço trouxe alguns bons resultados; por outro lado, ao ignorar a potência de outras possibilidades argumentativas, este tipo de apologética acabou também gerando certa resistência entre as pessoas não cristãs. A fim de alcançar a todos, neste texto apresentamos uma “nova” proposta para a defesa da fé cristã no espaço público. A partir do texto de Fl 2,5-11 são retirados princípios existenciais ancorados no ensino da imitatio Christi para uma apologética mais encarnacional dentro do espaço-tempo. Acreditamos que o hino cristológico forneça substrato consistente para uma defesa da fé muito mais rica e orgânica, tendo uma maior semelhança com a vida, morte e ressurreição de Jesus Cristo.

Published: October 2023

The magnetic properties of Mn-Zn ferrites depend strongly on the microstructure, chemical and phase composition. In this paper the effect of synthesis and sintering conditions on the structure, phase composition and properties of Mn-Zn ferrites is investigated. The specimens for the study were obtained by pressureless sintering. The magnetic properties were measured on a B-H analyzer. The structure was investigated by XRD and SEM. Materials with an average grain size of 2.2 μm were obtained by sintering at a temperature of 1265 °C. It was found that an increase in the synthesis temperature from 700 to 1000 °C promotes the growth of the initial magnetic permeability of these materials from 1100 to 1370. The rapid cooling of the powders synthesized at 1000 °C allows maintaining a high content of the spinel phase. In the structure of materials obtained by sintering powders with initially high spinel content at 1300 °C, grains of abnormally large size are formed. This leads to an increase in the initial permeability, magnetic induction at Hm = 1200 A/m, f = 10 kHz and magnetic losses at high frequencies (up to 500 kHz). A material with fine-grained structure was obtained by using air at the heating stage of pressureless sintering. This contributed to the reduction of magnetic losses without a significant decrease in Bm.
