Introduction:
Previous studies have shown that bioactive glass (BG) can enhance the formation of hydroxyapatite under simulated body fluid (SBF) conditions when combined with mineral trioxide aggregate (MTA). This study aims to assess the impact of BG-supplemented MTA on the biocompatibility and mineralization potential of dental pulp stem cells (DPSCs).
Methods:
We prepared ProRoot MTA (MTA) and MTA supplemented with 2% and 4% BG. Five passages of DPSCs were utilized for the experiments. The DPSCs were subjected to various tests to determine their morphology, viability, cell migration, and adhesion assay. Additionally, mineralization ability was assessed through SBF immersion treatment, alkaline phosphatase (ALP) activity test, Alizarin red S (ARS) staining, and real-time quantitative polymerase chain reaction (RT-qPCR) analysis.
Results:
The biocompatibility of BG-supplemented MTA was found to be comparable to that of conventional MTA, as demonstrated by the cell counting kit-8 (CCK-8) assay, cell migration, adhesion assays, and cell morphology on cement surfaces. Under SBF treatment, MTA supplemented with BG, particularly at a concentration of 4%, exhibited higher mineralization potential than conventional MTA in the ALP activity assay. This was supported by denser ARS staining, increased ALP activity, and higher expression of dentin sialophosphoprotein (DSPP), ALP, and bone morphogenetic protein-2 (BMP-2) in the SBF-treated MTABG group.
Conclusion:
Our study revealed that the biocompatibility of BG-supplemented MTA is similar to that of conventional MTA. Additionally, under SBF treatment, BG-supplemented MTA displayed enhanced mineralization potential, indicating that BG supplementation can augment the mineralization capabilities of MTA.
A Brand-New Algorithm for Mapping Algal Biomass in Lakes
Authors: Yu Zhengyang , Ma Ronghua , Hu Minqi , Xue Kun , Cao Zhigang , Xiong Junfeng
Published: January 2025

Column-integrated algal biomass has been recognized as a more logical proxy for the evaluation of lake eutrophication. Here, an algorithm with a 3-step framework is put forward for algal biomass mapping in 3 lakes of China (Lake Hongze, Lake Taihu, and Lake Chaohu). It can be summarized in step 1: inversion of surface chlorophyll a (Chl
a
), step 2: inversion of diffuse attenuation coefficient of the photosynthetic active radiation [
K
d
(PAR)], and step 3: estimation of algal biomass with a pretrained generalized additive model. The proposed algorithm outperforms the result-oriented and process-oriented methods in terms of accuracy in 3 lakes (the root mean square error [RMSE] values for datasets of Lake Hongze, Lake Taihu, and Lake Chaohu were 5.09, 8.21, and 3.90 mg/m
2
, respectively). Validated with match-up satellite data, the algorithm generates acceptable results (RMSE = 5.69 mg/m
2
, mean absolute percentage error = 30.9%,
N
= 16). Another important discovery is that the extremum of algal biomass of the entire lake (B
tot
) does not always coincide with that of total surface Chl
a
. For example, the maximum total surface Chl
a
was recorded in 2016, whereas the maximum B
tot
of Lake Hongze was observed in 2020. For Lake Taihu, 3 peaks of B
tot
appearing in 2017, 2019, and 2021, respectively, did not coincide with those of total surface Chl
a
. For Lake Chaohu, the interannual B
tot
followed a bimodal pattern that differed from the pattern of interannual total surface Chl
a
. The proposed algorithm plays an indispensable role in broadening the horizon for algal biomass inversion.

The Artificial Hero – The Ethical Dilemma of Portraying an Anti-Hero in an Audiovisual Product
Authors: Kvetanová Zuzana , Voleková Katarína
Published: January 2025

The present scientific study focuses on the evaluation of the ethical dilemma or the media image of an artificially created heroic character, namely the person of a serial killer in a modern criminal audiovisual product. Specifically, it is a reflection on the modes of depiction of the killer in the chosen research material – the episodic work Dahmer – Monster: The Jeffrey Dahmer Story (Brennan & Murphy, 2022). The theoretical background of the study is represented by the definitions of the key terms, namely the terms archetype, stereotype, artificial hero (anti-hero), violence or the genre of crime, whose meaning becomes crucial in the context of the issue under study. The mapping and at the same time a detailed description of the ways of presenting the anti-heroic character (the killer) in the chosen (popular) audiovisual product is the essence of the subsequent case study. Moreover, in the context of the issue we have addressed, we believe that the creators of the aforementioned media product are largely working with the values and features of mainstream (episodic) works, which from our point of view is the main determinant of the success of the pertracted work, but at the same time it is a significant ethical dilemma in correlation with the nature of the anti-heroic character. With the intention of answering the given premise, qualitative content analysis or narrative analysis and characteristic logical-conceptual procedures are used. Thus, the aim of this study is to extend the existing knowledge concerning the question of the position of the artificial hero (serial killer) in the audiovisual crime work in the form of a theoretical-empirical reflection.

Participative Culture in AI Models: Case Study of Stable Diffusion
Authors: Novanská Škripcová Lucia
Published: January 2025

Until recently, participatory culture was an area that was mainly manifested in media products, fandom products and, logically, in culture. However, with the advent of AI models, especially text-to-image, this statement is no longer valid. Of all the models for generating imagery, the best example is Stability AI’s Stable Diffusion, which, unlike others, is open-source. This means that it is possible to train custom datasets in each base model to generate only specific content. These datasets are created and trained by users, who then aggregate them on selected platforms, where they make their creations available for other users to work with, try out, and share their images. They evaluate each other, advise each other on how they arrived at a given result, etc. Effectively creating a participatory culture based on knowledge and experience sharing. Given this characteristic, it is possible to produce creative and imaginative products, but the result can also be harmful content, e.g. not suitable for minors or for sensitive audiences, such as sexually explicit content or violent and gore content. In this article I try to cover as many aspects of participatory culture in AI models as possible, with detailed consideration of Stable Diffusion and its positive and negative attributes.

Authors: Vadkertiová Andrea , Černá Jana
Published: January 2025

Although the history of cryptocurrencies is very short, these digital assets have revolutionised many areas, including marketing communications. Cryptocurrencies are also proving to have a significant impact on innovations in marketing communications. Companies that enable cryptocurrency payments are becoming a symbol of progress and innovation. Despite the relatively short period of use, there are now a large number of cryptocurrencies that differ in their utility, size of market capitalisation or the existence of their own network or platforms. What they have in common is that the possibility of using them to trade goods and services has a significant impact on the image of companies, predominantly among technologically oriented customers. The paper discusses the development and latest knowledge about cryptocurrencies as well as emerging trends in the context of marketing communication in the crypto market. The use of cryptocurrencies is an ever-expanding trend and its forecasts in conjunction with modern marketing communications for the future are very optimistic.

Published: January 2025

This research aims to explore the portrayal of artificial intelligence (AI) characters in film through theoretical reflection and narrative analysis. By examining five films selected from a list of top AI-centered movies, we aim to identify recurring archetypes, personality traits, and values associated with AI characters. The study’s primary goal is to construct a comprehensive profile of AI protagonists, informed by established theoretical frameworks and narrative structures. Our analysis focuses on categorizing these characters according to archetypes, traits, and values to address the following research questions: What archetypes are most commonly attributed to AI characters in modern media? What traits define these AI personas? What values are prioritized by AI characters within these narratives? Additionally, the study explores how these portrayals reflect societal attitudes towards AI, including the hopes, fears, and ethical considerations surrounding its integration into daily life. We also examine the evolution of AI representations, considering how technological advancements and cultural shifts influence cinematic depictions. By situating our findings within broader media and cultural studies, we aim to provide insights into the role of storytelling in shaping public understanding of AI. Ultimately, this work contributes to ongoing debates about the intersection of technology, ethics and creativity, and offers a diverse perspective on how artificial intelligence is represented and reimagined in film.

Authors: Zábojník Rastislav , Hromada Viktor
Published: January 2025

Generative artificial intelligence (AI) is increasingly integrated into higher education, offering advanced opportunities for personalized learning and tailored approaches that address students’ specific needs. This study examines the influence of generative AI on the education of Generation Z, emphasizing its role in fostering critical thinking, its psychological implications, and its potential to transform traditional pedagogical methods. Employing a methodological framework of systematic literature review and critical analysis of national and international studies, the findings reveal that generative AI can significantly enhance student motivation and engagement. Personalized content delivery facilitates learning and supports the successful completion of complex academic tasks, promoting the development of analytical and metacognitive skills necessary for navigating intricate information landscapes. However, over-reliance on AI risks diminishing students’ independent problem-solving abilities, underscoring the need for balanced integration of this technology in educational practices. The study further highlights challenges such as digital overload, which may adversely affect mental health, and reduced social competence due to decreased human interaction. In response, a strategic implementation of generative AI is recommended, designed to optimize its benefits while mitigating risks to students’ social and emotional development. Generative AI should be leveraged as a supportive tool to enhance the educational experience, with a strong focus on ethical standards and holistic student growth. Its effective integration should address technical, cognitive, social, and emotional dimensions of learning, contributing to the sustainable development of students in the digital era.
A Study on the Causes of Social Inequality in North Korea: Focusing on the Placement of High School Graduates into Rural Areas
Authors:   Public Policy Research Institute, Korea University, Oum Hyun-suk
Published: January 2025

The purpose of this study is to analyze the placement of high school graduates in rural areas during the Kim Jong Un era from the perspective of social inequality and class immobility. The findings of this study reveal that the policy of occupational inheritance and regional origin fixation not only restricts opportunities for career choice but also perpetuates social inequality across generations. The results indicate that North Korea's repeated approaches to addressing rural issues from the past to the present have led to an increasing number of young people turning away from rural areas. As these vacancies are filled by high school graduates and orphans, social inequality is further exacerbated. This study is significant in that it explores the history of rural mobilization and placement of high school graduates in North Korea, as well as the issues of inequality arising in this process.

Authors:   Public Policy Research Institute, Korea University, Kim Chang-hwan , Jee Hyo-keun
Published: January 2025

Kim Jong-un ascended to power after the death of Kim Jong-il on December 17, 2011. Since then, he has faced numerous challenges and threats. Despite this difficult environment, the Kim Jong-un regime has not only endured but has also become more resilient, maintaining a high level of stability.
This study aims to analyze the durability of the Kim Jong-un regime. To achieve this, Kim Jong-un's political leadership over the power elite is established as a new analytical framework. In this study, the dependent variable is the change in the durability of the Kim Jong-un regime, while the independent variable is Kim Jong-un's political leadership in relation to the power elite. The parameters are defined by evaluating Kim Jong-un's political leadership, with crisis management ability and regime stability serving as the evaluation criteria. Consequently, a new analytical framework is employed to examine the impact of Kim Jong-un's political leadership tendencies and the evolving attitudes of the power elite on North Korean society as a whole, particularly focusing on changes in the durability of the Kim Jong-un regime following the Eighth Party Congress.
As a result of the study, the durability of the Kim Jong-un regime has gradually strengthened over time compared to its initial period in power. Notably, following the 8th Party Congress, the regime has maintained a stable and increasingly robust state of resilience.
Rola Rosji jako wiodącego kraju ZSRR podczas II wojny światowej w świetle podręczników radzieckich. Część I
Authors: Żukowska Maria
Published: January 2025

Analiza radzieckich podręczników do historii z okresu powojennego do czasów pierestrojki Gorbaczowa stanowi kluczowy obszar badawczy, dotyczący wpływu treści edukacyjnych na kształtowanie świadomości historycznej. W tych wydaniach Wielka Wojna Ojczyźniana jest prezentowana jako monumentalne wydarzenie w historii ludzkości, ukazując jej charakter jako walki sprawiedliwej i wyzwoleńczej. Zwraca się uwagę na podkreślanie przewagi oraz zalet ustroju socjalistycznego, a także na wzrost międzynarodowej pozycji Związku Radzieckiego. Jednakże, mimo patriotycznego ducha kształtowanego wśród uczniów analiza wykazuje, że „szkolna” historia wojny była pełna przemilczeń, eufemizmów i ograniczeń. Elementy te były celowo stosowane w celu promowania wyższości systemu radzieckiego. Taka selektywna prezentacja mogła kształtować jednostronne przekonania i zniekształcać obraz historii, co miało wpływ na świadomość historyczną społeczeństwa radzieckiego.
Forearm vein pattern recognition using features from visible and NIR images
Authors: Choraś Ryszard S.
Published: January 2025

Forearm vein recognition is one of many available methods used for identification. However, forearm veins can be considered more secure compared to other biometric traits because the veins are inside the human body and therefore not easily manipulated. Veins possess several properties that make a good biometric feature for personal identification: 1) they are difficult to damage and modify; 2) they are difficult to simulate using a fake template; and 3) vein information can represent the liveness of person. Features were extracted from each pair of visible and NIR images. For the visible images, feature extraction was done using the Gabor filter. For the NIR forearm images, a crossing number was used to extract properties of the veins e.g. bifurcation. We present the results of the recognition of forearm veins patterns that show the suitability of the method for biometric identification purposes.

Authors: Telnov Anatoliy
Published: January 2025

Introduction. In the modern conditions of health care development, the creation of a quality management system in medical organizations is the basis for ensuring the effectiveness of modern medicine. In Ukraine, the quality of medical care is a criterion for the health care system. Improving the quality of medical services is one of the most urgent problems, as stated in the Concept of quality management of medical care in the field of health care in Ukraine. Ensuring the quality of medical services is the basis of the national policy in the field of health care. The creation of certain medical technologies has significantly improved the quality of medical care, changed the course of many diseases that were previously considered incurable. At the same time, for the effective management of the quality of medical services, the implementation of ISO 9001 standards is necessary, the basis of which is orientation to the consumer of services. This will make it possible for medical institutions to provide better services and guarantees to consumers regarding the satisfaction of their needs.
Purpose of the article is to conducting a marketing analysis of consumers regarding their receipt of preventive medical services in the conditions of the development of the modern health care system in Ukraine, taking into account the requirements of international quality standards.
Method (methodology). The methods of system analysis, classification and comparative analysis, marketing analysis of consumers are used for the research.
Results. The experience of undergoing a medical examination during the 2020 was analyzed among respondents who underwent a medical examination for preventive purposes and performed fluorography, electrocardiogram, visited doctors (dentist, urologist, gynecologist), did mammography and passed cytology tests. A tendency to decrease visits to doctors was identified and its reasons were analyzed. The state of passing a medical examination at a urologist and gynecologist was studied, depending on the level of education of the respondents. The experience of undergoing a medical examination by male and female urologists and gynecologists over the course of a year is characterized based on the assessment of respondents' attitudes. Based on the obtained results of the marketing analysis of consumers, the need for a mandatory medical examination is substantiated in order to prevent diseases in the future for the population and avoid many incurable diseases. It is argued that effective management of a medical organization is impossible without ensuring the quality of medical services, which necessitates the introduction of modern quality management systems based on international quality standards ISO 9000 in medical institutions.
Carbon dioxide sequestration and oxygen production in miscanthus plantations
Authors: Hayda Yuriy , Fuchylo Yaroslav , Brych Vasyl , Haida Taras , Borysiak Olena , Shuvar Antin
Published: January 2025

Introduction. Giant Miscanthus (Miscanthus giganteus J.M. Greef & Deuter ex Hodkinson and Renvoize) is widely used in many countries as an important bioenergy crop for producing various types of solid biofuels. Miscanthus plantations, which can yield significant amounts of phytomass, can also serve as a source of other environmental services, such as sequestering carbon dioxide, thereby contributing to climate change mitigation, and producing certain volumes of oxygen necessary for the survival of other living organisms.
Objective. The aim of the study is to determine the carbon sequestration volumes and oxygen production on Miscanthus plantations, as well as to develop models of their age-related dynamics.
Method. Carbon Stock was assessed using the IPCC (Intergovernmental Panel on Climate Change) methodology, which involves multiplying the value of absolutely dry biomass by the carbon concentration (CF), accepted as 0.50. To determine the oxygen productivity of Miscanthus, methodological approaches based on determining two indicators were used: the absolutely dry state of phytomass and the mass of oxygen produced during photosynthesis in the formation of absolutely dry organic matter.
Results. Using data on the solid biofuel output depending on the yield of giant Miscanthus stems and the percentage of dry matter in the harvested biomass, and converting it into phytomass stock, we determined the carbon sequestration capacity of the aboveground phytomass of giant Miscanthus and its oxygen productivity, presented in nomogram format. Depending on the yield of green Miscanthus stems (with 50% moisture content), the carbon sequestration volumes per hectare of plantation may vary from 1.25 to 12.5 t/ha, and the oxygen production volumes from 3.0 to 30.0 t/ha. The dynamic model of Miscanthus' carbon sequestration capacity shows that annual carbon sequestration volumes increase at a decreasing rate from a one-year plantation (approximately 2 t/ha) to 8-10 years (about 9 t/ha), then decline over the next five years to 7 t/ha. Carbon dioxide sequestration in the aboveground phytomass of Miscanthus is short-term; thus, the carbon balance in the atmosphere can be more significantly influenced by carbon sequestration in the underground phytomass of Miscanthus as well as in soil organic matter.

Authors: Sladkevičius Petras , Jakubauskienė Marija
Published: January 2025

Įvadas ir tikslas. Šiuolaikinė visuomenės sveikata re­miasi „vienos sveikatos“ paradigma, grindžiama inte­graliu požiūriu į žmonių ir gyvūnų sveikatą, augalus bei juos supančios aplinkos tarpusavio sąsajas. Bitininkai, prisidėdami ne tik prie bičių išsaugojimo, bet ir tiesiogiai dalyvaudami sveikatos stiprinimui skirtų bičių produktų gavyboje, propaguodami apiterapiją, atspindi „vienos sveikatos“ koncepto integralumą. Bitininkavimas pasi­žymi intensyvesniais ryšiais su gamta, unikalia gyven­sena ir geresne subjektyviai vertinama sveikata. Tyrimo tikslas – įvertinti Lietuvos bitininkų pasitenkinimą gy­venimu bei su juo susijusius sveikatos ir gyvensenos rodiklius.

Medžiaga ir metodai. 2023 metų lapkričio – 2024 metų vasario mėnesiais buvo atliktas paplitimo tyrimas tarp Lietuvos bitininkų. Tyrimo imtį sudarė reprezentatyvi 369 bitininkų kohorta. Tyrimo duomenų rinkimui tai­kytas mišrus duomenų rinkimo būdas (e-apklausa ir spausdintos anketos). Tyrimo priemonė buvo sudaryta iš trijų dalių anoniminės anketos, kuri apima sociode­mografinius kintamuosius, klausimus apie sveikatą ir gyvensenos veiksnius bei pasitenkinimą gyvenimu (tai­kytas Pasitenkinimo gyvenimu klausimynas, Cronbach alpha=0,893). Duomenų analizė atlikta naudojant IBM SPSS 29,0. Buvo vertinami dažniai, 95% pasikliautiniai intervalai, chi-kvadratas, Mann–Whitney U, Kruskal– Wallis testai ir daugianarė regresinė analizė buvo naudota duomenų analizei.

Rezultatai. Tyrime dalyvavo 73% (n=270) vyrų ir 27% (n=99) moterų. Vidutinis tyrimo dalyvių amžius 57,8 me­tai (SN=14,4). 77,8% tyrimo dalyvių būdingas aukštas, 14,9% − vidutinis ir 7,3% žemas pasitenkinimo gyve­nimu lygis. Sudaryti trys statistiškai reikšmingi daugiana­rės regresijos modeliai tarp trijų amžiaus grupių atskleidė, jog pasitenkinimas gyvenimu buvo susijęs su skirtingais sveikatos rodikliais. Remiantis sudarytu regresijos mo­deliu (=0,37, F=11,87, p<0,001), jaunesnių nei 50 metų bitininkų grupėje aukštą pasitenkinimą gyvenimu lėmė geras savo sveikatos vertinimas (β=0,214, p=0,031), mažesnis kūno masės indeksas (β=-0,210, p=0,016) bei mažesnis rūkymo dažnis (β=-0,237, p=0,005). 50-74 metų bitininkų grupei sudarytas modelis (=0,25, F=11,89, p<0,001) parodė, kad subjektyvusis dantų ir dantenų bū­klės vertinimas (β=0,259, p<0,001), rūkymo dažnis (β=- 0,209, p<0,001) bei jaustas fizinis skausmas (β=-0,193, p=0,003) buvo susiję su pasitenkinimu gyvenimu. 75 metų ir vyresnių tiriamųjų modelis (=0,33, F=10,22, p<0,001) patvirtino, jog geresnė subjektyviai vertinama sveikata (β=0,366, p=0,012) bei silpnesnis jaučiamas fizinis skausmas (β= -0,131, p=0,027) lėmė didesnį pa­sitenkinimą gyvenimu.

Išvados. Didžioji dalis Lietuvos bitininkų savo sveikatą vertino gerai arba labai gerai. Kas penktas bitininkas rūkė, daugiau nei pusė turėjo antsvorio arba buvo nutukę. Daugumos bitininkų pasitenkinimo gyvenimu lygis buvo aukštas. Jį lėmė geresnė sveikatos, dantų ir dantenų bū­klė, jaustas silpnesnis fizinis skausmas, mažesnis rūkymo dažnis bei mažesnis kūno masės indeksas.

Futbolininkų fizinis pasirengimas ir traumų rizika pri­klauso nuo intensyviai dirbančių raumenų energijos apykaitos. MCT1 (monokarboksilazės transporterį 1 ko­duojantis genas (angl. Monocarboxylate Transporter 1), polimorfizmas rs1049434 (c.1470T>A, p.Glu490Asp), reguliuojantis laktato apykaitos pokyčius sportuojant, gali lemti futbolo žaidėjų raumeninio audinio savybes. Šio tyrimo tikslas buvo išanalizuoti ir įvertinti Lietuvos profesionalių futbolininkų ir jų pogrupių pagal aikštelėje užimamą poziciją, genetinį fizinio pasirengimo ir traumų rizikos profilį, remiantis MCT1 rs1049434 polimorfizmu. Tyrimas apėmė 150 vyriškos lyties Lietuvos profesiona­lių futbolo žaidėjų ir 150 profesionaliai nesportuojančių vyrų. Tiriamųjų genotipavimas atliktas taikant tikro laiko polimerazės grandininės reakcijos metodą. Statistinė duo­menų analizė atlikta naudojant R Commander įrangą (v.2.8-0). Nustatyta, kad tarp futbolininkų MCT1 TT ge­notipas dažnesnis nei kontrolinėje vyrų grupėje (45,33% vs 34,00%, p = 0,039). Taip pat genotipų dažniai reikš­mingai skyrėsi tarp futbolininkų pogrupių pagal aikštėje užimamą poziciją: gynėjai, puolėjai ir saugai pasižymėjo panašiu TT genotipo dažniu (45-50%), o tarp vartininkų vyrauja heterozigotinis TA genotipas. Be to, MCT1 T alelis ir TT genotipas pasižymi apsauginiu nuo traumų poveikiu (ŠS = 0,216, PI 0,068 – 0,683, p = 0,009). Lie­tuvos profesionaliems futbolo žaidėjams nustatytas pa­lankus aerobiniam ir anaerobiniam pajėgumui MCT1 TT genotipas, susijęs ir su mažesne sportinių traumų rizika.
MOKYKLŲ VADOVŲ POŽIŪRIS Į NEGALIĄ TURINČIŲ VAIKŲ ĮTRAUKIMĄ Į BENDROJO UGDYMO PROGRAMAS VYKDANČIAS MOKYKLAS: VERTINIMAS PAGAL VADOVŲ BEI MOKYKLŲ CHARAKTERISTIKAS

Įtraukusis ugdymas yra šiuolaikinės švietimo sistemos prioritetas, kuriuo siekiama užtikrinti lygiavertį ugdymą visiems vaikams. Ugdymo įstaigų vadovų požiūris yra labai svarbus sėkmingo įtraukiojo ugdymo veiksnys.

Tyrimo tikslas. Atsižvelgiant į socialines ir demografi­nes vadovų bei mokyklų, kurioms jie vadovauja, cha­rakteristikas, įvertinti mokyklų vadovų požiūrį į negalią turinčių vaikų įtraukimą į bendrojo ugdymo programas vykdančias mokyklas.

Medžiaga ir metodai. Anketą užpildė 115 Vilniaus aps­krities bendrojo ugdymo programas įgyvendinančių mo­kyklų vadovų. Atsižvelgiant į socialines ir demografines vadovų bei mokyklų, kurioms jie vadovauja, charakte­ristikas, nagrinėtas respondentų pasiskirstymas atsakant į klausimą apie tai, ar visi negalią turintys vaikai, res­pondentų nuomone, turėtų mokytis bendrojo ugdymo programas vykdančiose mokyklose.

Rezultatai. Pusė respondentų (50,9 proc.) nesutiko su teiginiu, kad „visi negalią turintys vaikai turėtų mokytis bendrojo ugdymo programas vykdančiose mokyklose“. Dažniau su šiuo teiginiu nesutiko magistro arba mokslų daktaro laipsnį turintys ugdymo įstaigų vadovai (38,3 proc. prieš 12,2 proc., p<0,05). Pagal kitas nagrinėtas vadovų bei mokyklų charakteristikas (vadovų lytį, amžių, vadovavimo ir darbo švietimo srityje stažą, savivaldybę, kurioje veikia mokykla, ugdomąją kalbą mokykloje, mokyklos vietą, tipą, pavaldumą, mokinių, mokytojų, mokytojų padėjėjų ir negalią turinčių mokinių skaičių) reikšmingo nuomonės šiuo klausimu skirtumo nebuvo nustatyta (p>0,05).

Išvados. Kas antras Vilniaus apskrities bendrojo ugdymo programas įgyvendinančių mokyklų vadovas nepritaria, kad visi negalią turintys mokiniai turėtų mokytis ben­drojo ugdymo programas vykdančiose mokyklose. Nors aukštesnio lygio išsilavinimą įgiję mokyklų vadovai visų negalią turinčių mokinių ugdymui bendrojo ugdymo pro­gramas įgyvendinančiose mokyklose nepritaria dažniau, vadovų požiūris šiuo klausimu visų kitų nagrinėtų soci­alinių ir demografinių veiksnių atžvilgiu, įskaitant mo­kytojams tenkantį darbo krūvį, yra panašus.

Tyrimu siekta nustatyti mokinių, sergančių lėtinėmis ne­infekcinėmis ligomis, savirūpos proceso organizavimo ugdymo įstaigose ypatumus. Atliktas momentinis papli­timo tyrimas, kurio metu anoniminės anketinės apklausos būdu 2024 m. vasario mėnesį apklausti 85 tėvai, kurių vaikams buvo organizuojamas savirūpos procesas ben­drojo ugdymo įstaigose. Apskaičiuoti 95 proc. pasikliau­tiniai intervalai (PI). Pasiskirstymo skirtumams nustatyti buvo panaudotas Pearson chi kvadrato testas. Skirtumas laikomas statistiškai reikšmingu, kai p≤0,05. Nustatyta, kad 56,5 proc. tiriamųjų žinojo, kas yra mokinio savi­rūpa. 49,4 proc. apie savirūpos proceso organizavimą sužinojo iš mokykloje dirbančių visuomenės sveikatos specialistų, 57,6 proc. respondentų manė, kad savirū­pos procesas palengvina mokinio dalyvavimą ugdymo procese. Kas ketvirtas (25,9 proc.) apklaustasis savirū­pos proceso organizavimo metu susidūrė su sunkumais. Daugiausia tiriamųjų (31,8 proc.) nurodė šiuos sunku­mus: neaiški savirūpos plano forma, kurią sunku pildyti, netikslios gydytojų rekomendacijos bei mokytojų ir kitų mokykloje dirbančių specialistų pirmosios pagalbos žinių trūkumas. 47,1 proc. respondentų nurodė, kad informa­cijos apie savirūpos procesą jiems pakanka, o 73,5 proc. apklaustųjų manė, kad savirūpos procesą reikia tobulinti. Daugiausia tėvų (51,6 proc.) manė, kad savirūpos pro­cesą padėtų patobulinti informacijos sklaidos apie gali­mybę mokyklose teikti savirūpos pagalbą mokiniams, sergantiems lėtinėmis neinfekcinėmis ligomis, didinimas ir gerinimas bei visuomenės sveikatos specialistų ir kitų mokyklos darbuotojų kompetencijų plėtra.

Pristatomas 37 metų moters, 6 metus sergančios lėtiniu autoimuniniu tiroiditu ir hipotireoze, atvejis, kai, siek­dama pagerinti tiroidito valdymą, pacientė savarankiškai laikėsi mitybos intervencijos, nutraukdama kviečių, vė­liau ir glitimo turinčių produktų bei pieno ir jo produktų vartojimą, taip pat laikėsi papildomų gydytojo gastroente­rologo rekomenduotų mitybos pokyčių. Dviejų metų lai­kotarpiu, kol buvo taikoma mitybos intervencija, pacientė nejautė bendros savijautos ar virškinimo trakto simptomų pagerėjimo, skydliaukės veiklos rodikliai (tireotropinis hormonas ir laisvas tiroksinas) ir skydliaukės antikūnai reikšmingai nekito, tačiau sumažėjo laisvo trijodtironino rodiklis. Skyrus kombinuotą gydymą levotiroksinu ir trijodtironinu, bendra būklė pagerėjo, tačiau išliko var­ginantys virškinimo trakto simptomai. Atvejo analizė parodė, kad sergant autoimuniniu tiroiditu ir hipotireoze, būtina nuolat stebėti visus skydliaukės veiklos rodiklius, ypač jei pacientai turi dietos ribojimų ar serga virškinimo trakto ligomis, o visavertė mityba, turinti pakankamą bal­tymų, mikroelementų ir vitaminų kiekį, yra labai svarbi tinkamai skydliaukės veiklai užtikrinti.

Slaugytojai dažnai yra pirmoji grandis, su kuria susiduria pacientai, atvykę į Priėmimo-skubiosios pagalbos skyrių, todėl svarbu, kad slaugytojai būtų kultūriškai kompeten­tingi, kad pacientams būtų suteiktos kokybiškos sveika­tos priežiūros paslaugos nepaisant jų tautybės, rasės bei įvairių socialinių ar kultūrinių veiksnių. Didėjant kitų kultūrų pacientų srautams ir kultūrinės kompetencijos reikšmingumui, susiduriama su slaugytojų kultūrinės kompetencijos iššūkiais. Tyrimo tikslas – nustatyti slau­gytojų kultūrinę kompetenciją ir iššūkius, bendraujant su kitų kultūrų pacientais Priėmimo-skubiosios pagal­bos skyriuje.

Tyrimo medžiaga ir metodai. 2024 m. vasario-kovo mė­nesiais buvo atliktas kiekybinis tyrimas taikant anoni­minę apklausą. Tyrimui atlikti buvo naudojama Slaugy­tojų kultūrinės kompetencijos skalės lietuviškoji versija, kurią sudarė keturios dalys: kultūrinio sąmoningumo skalė, kultūrinių žinių skalė, kultūrinio jautrumo skalė ir kultūrinių įgūdžių skalė. Gautas Vilniaus universiteto Medicinos fakulteto Mokslinių tyrimų etikos komisijos pritarimas (Nr. 150000-KT – 326), tyrimo priemonės autorių sutikimas. Apklausa buvo vykdoma X ir Y li­goninėse, išdalinant spausdintines anketas Priėmimo-skubiosios pagalbos skyriuje dirbantiems slaugytojams. Tyrime dalyvavo 125 slaugytojai, sutikę dalyvauti ty­rime. Tyrimo duomenų statistinei analizei atlikti naudota „SPSS 21.0“ programa.

Tyrimo rezultatai. Slaugytojų kultūrinės kompetencijos balas buvo 138,4 balo iš 205. Aukščiausi balai buvo kul­tūrinio sąmoningumo poskalės (3,85±0,632), o žemiausi − kultūrinių įgūdžių poskalės (3,09±1,087). Dažniausia problema, su kuria susidūrė slaugytojai, teikdami pas­laugas kitų kultūrų pacientams, buvo kalbos barjeras (69 proc.), o didžiausios kliūtys kilo bendraujant su Europos šalių pacientais (26 proc.).

Išvados. Slaugytojų kultūrinė kompetencija vertinama kaip vidutinio lygio. Dažniausias iššūkis teikiant svei­katos priežiūros paslaugas kitų kultūrų pacientams buvo kalbos barjeras, o daugiausia bendravimo kliūčių kilo su Europos šalių pacientais.
