Authors:   Korean Society of Nursing Research, Lee Han Yi , Moon Woo Jong
Published: June 2024

Purpose : This study explores the influence of children’s happiness on their grit for successful growth and development, while investigating the moderating role of positive parenting attitudes. It aims to provide insights into children's mental health and internal development. Methods : The analysis employs secondary data from the 11th (2018) Panel Study of Korean Children. Participants' socio-demographic characteristics, children's grit, positive parenting attitudes, and variables associated with children's happiness were extracted. Descriptive statistics, correlation analyses, and hierarchical regression were employed to assess the moderating effect. Results : A positive correlation was found between parenting attitudes of both parents and the children's happiness and grit. Adding interaction terms of positive parenting attitudes and a child's happiness to the relationship between happiness and grit increased the explanatory power from 28.5% to 29.1%. Positive parenting attitudes have a moderating effect. Conclusion : To enhance children’s grit, interventions must address individual happiness and promote positive parenting attitudes. Prioritizing children's psychological well-being is crucial, highlighting the importance of cultivating positive parenting approaches. Tailored interventions for child well-being and parenting attitudes are essential.

Introduction: Endometrial cancer is the most prevalent cancer in women, and heavy metals, including cadmium, are among the factors associated with cancer development. Therefore, this study aimed to investigate the relationship between cadmium exposure and the risk of endometrial cancer using a systematic review and meta-analysis. Materials and Methods: In this systematic review and meta-analysis, which was conducted by the PRISMA guidelines, several databases, including PubMed, Scopus, Web of Science, Cochrane, and Google Scholar search engine, were searched without time restrictions until August 8, 2023. Data analysis was performed using STATA 14 software, and statistical significance was considered at P < 0.05. Results: The results of the analysis of six studies involving a total of 160,043 women (2282 in the case group and 157761 in the control group) showed that cadmium exposure had no significant effect on the risk of endometrial cancer development (OR: 1.02, 95% CI: 0.92-1.13). Furthermore, there was no statistically significant association between menopause and the risk of endometrial cancer development (OR: 3.91, 95% CI: 0.50–30.73). Additionally, there was no statistically significant association between body mass index >25 kg/m2 and the risk of endometrial cancer development (OR: 1.04, 95% CI: 0.86–1.26), with smoking and the risk of endometrial cancer development (OR: 0.91, 95% CI: 0.61–1.36) too. Furthermore, there was no statistically significant association between hormone therapy and the risk of endometrial cancer development (OR: 0.81, 95% CI: 0.63–1.04) as well. Conclusion: Our study demonstrated that cadmium exposure is not associated with an increased risk of endometrial cancer. However, further research in this area is recommended due to the limited number of studies available. Registration: This study has been compiled based on the PRISMA checklist, and its protocol was registered on the PROSPERO (ID: CRD42023462640).
A prospective study to assess the clinicopathological and prognostic value of BRAF V600E mutation in metastatic colorectal cancer
Authors: Aboulfadl Mona Taher , ELwakeel Hisham , Mostafa Mohamed , Shakweer Marwa , Elghamry Wesam
Published: June 2024

Introduction: BRAF is a protein kinase downstream of RAS in the RAS-RAF-MEK-ERK kinase pathway, the prevalence of BRAF mutation might be underestimated, while it is considered a major negative prognostic marker and is associated with resistance to standard chemotherapeutic regimens in metastatic colorectal cancer (mCRC) patients, justifying a personalized therapeutic approach in BRAF-mutated mCRC patients. Given this poor outcome in patients with BRAF-mutated mCRC, optimizing therapy is an important goal. Objectives: This study aimed to study BRAF mutation in patients with metastatic CRC and its association with clinicopathological factors and survival outcomes. Patients and Methods: This prospective study included 55 patients with histologically proven CRC with metastatic disease, either radiologically or pathologically proven. BRAFV600E mutation analysis was performed using the polymerase chain reaction (PCR) and reverse hybridization method on formalin-fixed and paraffin-embedded extracted DNA samples. Results: In our study, 55 patients were enrolled. The mean age was 49.5 years with male predominance. Among patients enrolled in the study, 54 were evaluated for survival over one year. The median progression-free survival (PFS) was 11.167 months, and the median overall survival (OS) was 34.5 months. BRAF V600E mutation was detected in 9.1% of patients and all of them presented with synchronous metastasis, with statistical significance (P = 0.0339). No significant difference was observed in clinicopathological factors, PFS, or OS between BRAF-mutant and wild-type patients. Only 48 patients were evaluated for their response to first-line therapy; it was found that most patients who did not receive targeted therapy had progressive disease with a statistical significance of P = 0.0450. A median PFS of 19.2 months was also noted with statistical significance (P = 0.0121). Conclusion: The BRAFV600E mutation is associated with more aggressive features, but no association with PFS or OS was found. Chemotherapy with the addition of targeted therapy has an impact on PFS. Further investigations are therefore warranted and the inclusion of BRAF-mutated mCRC patients in clinical trials needs to be encouraged.
Lupus-associated collapsing glomerulopathy; a current data
Authors: Ansari Narges , Salesi Mansour
Published: June 2024

Collapsing glomerulopathy is a rare but severe form of glomerular injury that can be accompanying by SLE (systemic lupus erythematosus). The pathogenesis of collapsing glomerulopathy in lupus is not well understood, and the treatment options are limited. The treatment of collapsing glomerulopathy in lupus is challenging. Immunosuppressive therapy with corticosteroids and cytotoxic agents is the mainstay of treatment. However, the response to therapy is often poor, and many patients progress to end-stage renal disease despite treatment. The use of newer agents such as rituximab and belimumab may offer additional options for the treatment of collapsing glomerulopathy in lupus. Further studies are required to better detect the underlying mechanisms of collapsing glomerulopathy in lupus and to develop more effective therapies for this condition.

Introduction: Statins reduce the cancer risk; however, non-Hodgkin lymphoma (NHL) evidence remains controversial. Therefore, we aimed to evaluate the relationship between statin consumption and NHL risk using a systematic review and meta-analysis. Materials and Methods: In this systematic review and meta-analysis, international databases, including Scopus, PubMed, Web of Science, Cochrane, and Google Scholar search engines, were searched without a time limit up to September 21, 2023. Data analysis was performed using STATA 14 software, and the significance level was considered P<0.05. Results: The results of combining 13 studies (9 case-control studies and 4 cohort studies) with a total sample size of 1142 740 subjects showed that statin consumption could reduce NHL risk by 22% (RR: 0.78; 95% CI: 0.69, 0.88). Statin consumption in cohort studies reduced NHL risk by 14% (RR: 0.86; 95% CI: 0.77, 0.95), but in case-control studies, it reduced NHL risk by 26% (RR: 0.74; 95% CI: 0.62, 0.90). Furthermore, statin consumption reduced diffuse large B-cell lymphoma risk by 24% (RR: 0.76; 95% CI: 0.67, 0.87) and marginal zone risk by 26% (RR: 0.74; 95% CI: 0.59, 0.93). However, it did not affect reducing the risk of chronic lymphocytic leukemia/small lymphocytic lymphoma (RR: 0.94; 95% CI: 0.85, 1.05), follicular (RR: 0.96; 95% CI: 0.83, 1.10), plasma cell neoplasms (RR: 0.97; 95% CI: 0.70, 1.33), T cell lymphoma (RR: 0.81; 95% CI: 0.55, 1.19) and B cell lymphoma (RR: 0.94; 95% CI: 0.44, 2.01). Conclusion: Statin consumption significantly reduced the risk of NHL, diffuse large B-cell lymphoma, and marginal zone but did not affect other NHL types.

Authors: Kushnarevych Andrii
Published: June 2024

Loyalty programs have long served as valuable tools for customer engagement and retention. Today, with the increasing availability of customer data, new methods for analysis and program optimization are becoming a necessity. Artificial Intelligence (AI) has also been a topic of high relevance in recent years, and its connection with loyalty programs has not been researched and discussed enough to date. In this paper we aim to explore the emerging topic of AI data analysis in the context of loyalty programs. We examine various applications of AI data analysis in loyalty programs, including personalized rewards and incentives, customer segmentation and targeting and fraud detection and risk management. Covering these possible applications of AI data analysis provides a general understanding of AI data analysis functioning and its integration into loyalty programs. The provided information also serves as a good basis for understanding how AI data analysis functions and may be applied in various fields. In our paper we look at the outcomes of AI data analysis applications in loyalty programs from the point of view of a customer who is using those programs as well as from the point of view of the brand who manages them. By analyzing the identified points, we then highlight the benefits and challenges of using AI data analysis in loyalty programs. Key research gaps are also presented, emphasizing the need for further research on the topic, with particular attention given to problems such as ethical considerations, data privacy concerns, and the transparency of AI models. The main goal of our article is to provide readers with complex information on the topic of AI data analysis usage in loyalty programs and the ways this technology may benefit customers and the brand in the selected context. The article is theoretical-empirical and is based on external information from trustworthy sources, both digital and printed, completed with our own research outcomes.
Teaching Research in an Employability-Focused Undergraduate Curriculum
Authors: Rich Martin
Published: June 2024

Employability has emerged as a key part of many universities’ strategies, with initiatives to integrate work with employers, and input from professional careers advisers, into course material.  This is especially relevant for business and management courses, and particularly at the undergraduate level offers some scope for courses to be differentiated through the nature of the interaction which they provide with employers. Undergraduate students are expected to learn some research techniques and to demonstrate an ability to carry out a measure of independent inquiry as part of their studies.  Superficially these research techniques can appear to represent a very different facet of academic study from employability, and be seen as training in purely academic techniques.  This paper explores the potential to build connections between research and employability and to harness students’ knowledge of research methods when working on practical business issues. This paper is based on experience of developing a series of projects which students in their final year of an undergraduate degree can carry out in partnership with employers.  These projects are on a smaller scale than independent projects that students have worked on in the past and allow for more focused aims and more structured supervision than other student research projects.  While the original motivation was to increase the structure and certainty for students their final year the approach has evolved to be aligned with the university’s policies around practical experience and employer engagement.  Therefore the project, while not mandatory for students, is positioned as one of a number of possible ways to gain practical experience, with the expectation that students will take up at least one of these options so that they will graduate with this experience. Setting up these projects has depended on collaboration between academics, careers advisors, and others involved with employer engagement including the team working with alumni.  The approach has been implemented across a range of business, management, and finance degrees and has proved effective in creating a connection between independent research and employability.

Authors: Cauchick-Miguel Paulo , Kohlbeck Eloiza , Tavares de Sousa Zomer Thayla
Published: June 2024

In the evolving field of Production Engineering, the robustness of case-based research plays a crucial role in theory development and practical application. Recognizing this criticality, this paper delves into a systematic examination of methodological rigor in Production Engineering case research, scrutinizing a significant corpus of research to discern patterns and practices in methodological execution. This work seeks to shed light on the prevailing trends and identify potential avenues for strengthening the methodological foundations of case study research within the Production Engineering domain. The search was based on case studies from select publications in the Scielo database, a relevant Brazilian source that make available journal articles published in journals in various areas of knowledge. The analysis delineates a framework of four quality criteria – construct validity, internal and external validity, and reliability – to augment methodological rigour. The findings reveal a critical need for a more explicit engagement with these criteria in research design, data collection, and analysis. The research highlights strategies to fortify rigour and, by extension, the quality of case-based research, paving the way for more robust theoretical contributions in Production Engineering. This work in progress not only considers the recent landscape of case-based research but also provides actionable insights to refine future research methodologies, ultimately fostering a paradigm of excellence in qualitative research. The enhancement of methodological rigour in Production Engineering case-based research within the scientific community in a developing country is of paramount importance. As scholars strive to amplify their voices in the international arena, the meticulous application of robust research methodologies becomes critical. It serves not only to fortify the validity and reliability of findings but also to ensure the reproducibility of research. Enhancing methodological rigour aids in building a legacy of credibility and trust in the Brazilian scholarship that can contribute significantly to both regional and global advancements in Production Engineering.
Heuristics in Labor Management: An Application of Modified Camel Algorithm
Authors: Demiral Mehmet Fatih
Published: June 2024

Modified Camel Algorithm (MCA) is a challenging algorithm applied to engineering problems in 2016, 2019, and 2021. MCA can be implemented to the field of business, economics, labor management, and science compared to the other techniques. The pure MCA solves optimization problems effectively and quite fast in literature. To develop and apply the mathematical model in labor management using the modified camel algorithm, it was combined with popular heuristics, such as constructive heuristic (MC), and then improved with local searches, for instance 2-opt, 3-opt, and k-opt. The suggested hybrid algorithms are tested under proper parameters. In the experimental study, random model datasets, and suitable parameters are used via uniform distribution. The experimental outcomes are given as best, average, std. deviation and CPU time for sample datasets with proper parameters. In short, the suggested hybrid metaheuristics find reasonable solutions of labor management in acceptable CPU time for all random datasets.

Religious iconography and topography in the garden art of Early Modern Europe.
Sources, interpretation, cultural context.
Authors:   Russian State University for the
            Humanities, Sokolov B. M.
Published: June 2024

The paper analyzes gardens and landscapes of the Renaissance, Mannerism and
Baroque with particular attention to moral themes and Christian symbols. I follow the
devel-opment of moral topography in the gardens by examples of Villa Hadriana, Villa
d’Este in Tivoli, Versailles, Tsarskoye Selo, Désert de Retz, Sanspareil, Regaleira. The
two types of gar-dens are identified: architectural (Castelo Branco, Bom Jesus do Monte
in Braga) and land-scaping (Bomarzo, Cetinale, Esztergom, Buçaco, Kuks, Valsanzibio).
The paper then turns to “sacred mountains” created in the foothills of Italian Alps as a
symbolic barrier at the bor-der of Protestant lands. The interplay of gardens themselves
and their descriptions, such as in “The Path of Purification”, the treatise by Francesco
de’ Vieri on Pratolino, 1587 and in the inscriptions in Valsanzibio, is also discussed.
Further in the paper I wonder about how moral programs of gardens can be studied and
incorporated in the history of ideas and religiosity. The work is based on the materials
of author’s travels and is illustrated with his photographs. Translations into Russian

Modelling And System Identification For Real Systems
Authors:   ,   Cork Institute of Technology, Murphy Karolyn
Published: June 2024

"The field of system identification and process parameter estimation is an area that has developed rapidly during the past few decades. The approach to the system identification problem can be influenced by many different aspects which include the specific purpose of the identification. In this thesis, system identification for the purpose of controller design is the central theme. Initially, the work will focus on a number of approaches to real system identification. Particular attention will be made to the classical non-parametric techniques and the more modern parametric estimation techniques using both open- and closed-loop real-time data. A voltage controlled dc motor plant will be used to help benchmark the various techniques. The work will then progress to the area of control relevant identification, which aims at achieving optimal control performance for a given system. The inter-relation between system identification and controller design is examined. Results from the dc motor plant will show that it is beneficial to use a number of controller design techniques to determine the best closed-loop response and hence the most suitable combination of model and controller. The knowledge gained and lessons learnt from the motor plant will then be applied to the main target of the work which is system identification and control of a pilot-scale milk pasteurisation plant. A comparison between non-parametric identification and both open- and closed-loop parametric identification methods will show that the non-parametric transient step response technique produces the most accurate and the simplest model. Also highlighted is that reduced plant model complexity produces significant improvements in both open- and closed-loop performance. Cascade feedback control simulations are also performed as a further addition to the single feedback control of the pasteurisation. Results show vast improvements in the overall control of the plant and the plant output performance."
Development Of A Low Jitter Multiplying Delay Locked Loop
Authors:   ,   Cork Institute of Technology, Kennedy Ian
Published: June 2024

"The clock generator is a critical component in high-speed wireline communication systems. The clocks in these systems mark time at precise regular intervals. Any deviation of the clock edges from these ideal time points is called jitter and it degrades the overall integrity of the communication system. This thesis looks at both phase locked loops (PLLs) and delay locked loops (DLLs) and their ability to provide these precise clocks. Expressions for the thermal noise-induced jitter in both the PLL and DLL are compared. From this, the DLL is shown to possess the potential for better jitter performance. However, to realise the potential of the DLL, another source of jitter peculiar to the DLL has to be reduced. This jitter in DLLs is caused by Static Phase Offset (SPO). The thesis details the causes of SPO and describes a number of good design practices for reducing it. It then describes an input and feedback clock phase interpolation technique which reduces SPO by half. Finally a novel chopping technique is used to essentially eliminate SPO resulting in a DLL which is ideal for high-speed wireline communication systems. Some of this work was published at the lEE Irish Signals and Systems Conference, which took place at Queens University Belfast, in June 2004."
Evaluation Of The Host Range Of Polyvalent Staphylococcal Bacteriophages To Control Mrsa (staphylococcus Aureus) From Irish Hospitals
Authors:   ,   Cork Institute of Technology, Elbreki Mohamed
Published: June 2024

This study describes firstly, the assembly of a collection of a varied spectrum of staphylococci which can be used to test the efficacy of bacteriophages for the biocontrol of problematic members of this genus. The collection assembled includes a variety of multi-antibiotic resistant MRSA (methicillin resistant S. aureus) strains, hVRSA (hetero vancomycin resistant S. aureus), VRSA and also teicoplenin resistant isolates. It also included a broad range of species of coagulase-negative {non-aureus) staphylococci including S. caprea, S. haemolyticus, S. saprophyticus, S. epidermidis, S. chromogenes, S. capitis, S. hominins and S. hyicus. All strains were characterized by morphology on Baird Parker, coagulase, antibiotic resistance profile (using twelve antibiotics) and Random Amplified Polymorphic DNA (RAPD) profiles. Secondly the study succeeds in bringing together and characterizing a group of phages, which successfully eliminate various members of the staphylococci assembled. These are phage CSl, phage DW2 and phage K. It was verified that phage K has an unusually broad host range in that its specificity extends beyond S. aureus to include many other species. In the course of the study, it was shown that certain MRSA strains exhibited a high degree of insensitivity against phage K. A natural method was therefore devised whereby the host range of phage K could be broadened to successfully form clear plaques on these insensitive strains. This was based on the principle of classical phage DNA modification to circumvent restriction activity in the insensitive MRSA strains. It was shown that when phage K was modified to become capable of plaque formation on one previously-insensitive strain, it could also lyse a significant number of additional MRSA strains. Finally, phage K was incorporated into a model hand-wash solution where it was repeatedly evaluated for its efficacy in reducing S. aureus numbers on human skin. Application of the hand wash conclusively resulted in a 90% reduction in number of S. aureus on human skin. This latter application may well have beneficial uses in hospitals.
Assessing the Role of Nature in Emergent Reading and Writing Activities in the Early Childhood Curriculum: A Study of Turkish Educational Practices
Authors: Yiğit Gençten Vahide , Aydemir Filiz
Published: June 2024

This study aims to examine how and to what extent nature is used in reading and writing activities in the early childhood curriculum in Türkiye. Using a document analysis method, the authors analyzed curriculum documents and activity plans from a preschool program and two activity books, identifying a total of 12 activities related to nature-based learning and emergent literacy. These activities were analyzed in terms of the development areas they supported, the types of activities, materials used, and themes covered. Our investigation into emergent reading-writing activities that utilized nature as a support or main subject yielded compelling findings. The curriculum documents showed that nature-based emergent reading-writing activities offer a wealth of potential for fostering young children's cognitive, linguistic, socio-emotional, psychomotor, and self-regulation skills. These activities are often integrative in nature, incorporating emergent reading-writing with other domains such as mathematics, language, art, and more. Our analysis of the curriculum documents also indicated that nature-based emergent reading-writing activities commonly employ a diverse array of materials, including both natural and unnatural resources. Moreover, we found that such activities frequently encompass a broad spectrum of vocabulary and concepts. These encompass a wide range of subjects, ranging from seasonal phenomena such as winter to societal issues such as human rights and citizenship to scientific concepts like reproduction and fermentation.

Designing a Cost-Efficient Belt-Driven 3D-Printed Syringe Pump
Authors: Ağır İsmail
Published: June 2024

In biotechnology, biomedicine, and bioengineering research, precise liquid transfer and control are essential. Laboratories depend on diverse pumps and fluid control systems, with syringe pumps emerging as a preferred option due to their compatibility with biological fluids. Due to the high cost and limited customization options in existing commercial syringe pumps, researchers have begun designing their own custom devices, utilizing the expanding 3D printing technology and open-source electronics. Nevertheless, 3D-printed pumps often integrate metal components such as lead screws and rods to create linear drives, leading to heightened costs and increased overall weight. Furthermore, lead screws can introduce backlash errors, affecting precision due to play between the threads of the nut. In this study, a 3D-printed syringe pump design is introduced based on the belt drive method, with a focus on minimizing the incorporation of metal components. Not only is cost reduction achieved by new design, but it also results in a lighter syringe pump while minimizing backlash errors. A sensitivity below 10 microliters, a cost of less than $41, and a weight under 250 grams were achieved by the newly designed pump. The effort to develop a 3D-printed custom syringe pump, which reduces reliance on external sources, particularly in constrained environments, is strengthened by the reduction of dependency on metal parts and the increased utilization of 3D printed components.

Dabei findet insofern die Heterogenität der Kinder Berücksichtigung, als diese ermuntert werden, sowohl eigenen Fragestellungen nachzugehen als auch sich an Frageimpulsen anderer zu orientieren. Weiterhin wird in der ISSU-Werkstatt eine Balance zwischen angeleitetem Experimentieren und freiem Explorieren geschaffen und das Lernen als aktive Wissenskonstruktion gefördert. Der Beitrag erörtert am Beispiel des Inhalts „Klima und Klimawandel“, wie die Kompetenzerweiterung von Studierenden in der ISSU-Werkstatt sowohl praxisnah als auch handlungsorientiert unterstützt werden kann.

Efectos de los créditos a la contratación en el mercado laboral argentino
Authors:   , Menduiña María Azul
Published: June 2024

Este trabajo evalúa el impacto de una política de créditos para la contratación implementada en Argentina en 2014, sobre distintos resultados laborales de las empresas. La reforma estableció subsidios diferenciados en las contribuciones patronales a pagar por los nuevos empleados, según el tamaño que las empresas tenían en una fecha previa al anuncio de la política. De esta forma, la medida introdujo una variación exógena en las contribuciones que las empresas debían abonar. Específicamente, los beneficios fiscales fueron considerablemente mayores para las empresas de menor tamaño. Utilizando un enfoque dinámico de diferencias en diferencias y datos administrativos, se analizan los efectos de esta intervención. Los hallazgos revelan un aumento significativo de 3,32 p.p. en las tasas de crecimiento del empleo para las pequeñas empresas en comparación con las medianas, sostenido durante varios años posteriores a la reforma. No se encontraron efectos significativos sobre los salarios. Finalmente, la política incentivó la formalización, generando un incremento de 0,40 p.p. en la probabilidad de contratar formalmente empleados previamente categorizados como monotributistas.
Key Factors Affecting Sustainable Economic Growth in the New Normal Era: An Empirical Analysis of Country Data
Authors:   Korea Trade Research Association, Jun Zhao Jun Zhao , Lee Seo-Young
Published: June 2024

Purpose - The global economy has entered a new normal era since the financial crisis of 2007 and 2008. In fact, advanced countries and those emerging have been faced with low growth, low interest rates, low prices, high unemployment, increased government debt, and stricter regulations. Nonetheless, some countries have achieved sustainable economic growth. We attempted to identify factors influencing sustainable economic growth in this era by empirically testing a model with data regarding economic indicators in 25 countries.
Design/Methodology - For this empirical test, a panel model was set with nine economic variables for 14 advanced and 11 emerging countries. We conducted both a panel unit root test and a cointegration test in order to measure the stationarity of the data. The results of these tests presented that there have been long-term balanced relationships among the variables. We also conducted another empirical analysis through the fixed effects model and random effects model, and performed a Hausman test to confirm that the fixed effects model was more valid.
Findings - Empirical evidence using the fixed effects model showed that the consumption level, capital formation, openness of international trade, urbanization, and innovation ability were significant in promoting the economic development of developed countries, whereas population has a negative impact on the economic development of these countries. In emerging economies, capital formation and education level had a positive effect on sustainable economic growth. Population, openness to international trade, urbanization, and industrial structure had negative impacts on sustainable economic growth. This research contained a certain level of originality in the sense that we analyzed the effects of critical economic indicators on the sustainable economic growth in representative countries that have developed economically in the new normal era.
Originality/value - Few studies focus on the inf luencing factors of sustainable economic development in a specific country. We may provide important implications for economic policy makers that want to grow their economies sustainably. We also may enrich a theoretical and practical basis on economic development.

Introduction: Since 2024, Russian R 2.1.10.3968-23, Guidelines for assessing health risks from exposure to chemical environmental pollutants, have been in effect, which opens up new opportunities for analyzing adverse human health effects of environmental factors.
Objective: To justify temporary deviations in drinking water quality taking into account new scientific evidence and using the methodology of human health risk assessment.
Materials and methods: For the current study, we selected 214 results of water quality testing before supply to the urban distribution system for the years 2019–2022. The statistical analysis was conducted in Microsoft Excel using descriptive statistical techniques. Temporary deviations were justified for indicators which median values exceeded hygienic standards. Risk assessment was conducted according to both cancelled and updated Guidelines and included substances with established reference doses and carcinogenic potency factors. We calculated carcinogenic risks, non-carcinogenic hazard coefficients and indices using standard exposure factors.
Results: The statistical analysis showed that median levels of boron and magnesium exceeded hygienic standards. According to the results of health risk assessment, values of carcinogenic and non-carcinogenic risks were at an acceptable level. Unacceptable levels were mainly determined for the exposure to arsenic, the concentration of which can be taken as zero in accordance with the new guidelines. Boron exposure did not significantly contribute to risk levels, while for magnesium the reference dose is absent.
Discussion: Questions are raised related to the lack of reference doses for certain chemicals and exclusion of some pollutants from the analysis.
Conclusion: The health risk assessment values calculated in accordance with the updated guidelines are within the acceptable range, indicating that there is no threat to health. This finding supports the establishment of temporary deviations for boron and magnesium.
Rola rodziny i przedszkola w kształtowaniu kompetencji społecznych dzieci w wieku przedszkolnym

Published: June 2024

Celem artykułu jest wskazanie znaczenia kompetencji społecznych oraz potrzeby ich rozwijania u dzieci w wieku przedszkolnym. Celem jest również ukazanie roli i zadań rodziców i nauczycieli przedszkola w kształtowaniu u dzieci tych kompetencji. Przedmiotem analizy uczyniono wybrane definicje kompetencji społecznych oraz zapisy Podstawy Programowej Wychowania Przedszkolnego, a także dwie funkcje rodziny - wychowawczą i socjalizacyjną, które są szczególnie istotne dla rozwoju kompetencji społecznych dzieci. Problem badawczy dotyczy tego, jaka jest rola i zadania rodziców i nauczycieli przedszkoli w kształtowaniu kompetencji społecznych  dzieci w wieku przedszkolnym.  W celu uzyskania odpowiedzi na ten problem przeprowadzono analizę wybranych tekstów psychologiczno-pedagogicznych, stosując metodę desk research. Człowiek jest istotą społeczną, dla prawidłowego rozwoju i efektywnego funkcjonowania powinien nawiązywać właściwe relacje z innymi ludźmi. Dotyczy to również najmłodszego pokolenia. Rozwijanie kompetencji emocjonalnych i społecznych, a zwłaszcza kompetencji interpersonalnych, może pomóc dzieciom w nawiązywaniu satysfakcjonujących relacji z rówieśnikami oraz zmniejszyć ryzyko występowania zachowań niepożądanych. Największą odpowiedzialność za wychowanie i uspołecznianie dzieci ponoszą ich rodzice. W realizacji funkcji wychowawczej i socjalizacyjnej powinno ich wspierać przedszkole, dlatego tak istotna jest  współpraca rodziców i nauczycieli przedszkoli.

Published: June 2024

Badania polskie i międzynarodowe wykazują poważne zmiany w zachowaniu i samopoczuciu dzieci, młodzieży i dorosłych po okresie pandemii oraz w związku z narastającą presją sprostania oczekiwaniom współczesnego świata. Niezbędne staje się wprowadzenie na każdym etapie edukacji programów mających na celu systematyczne wzmacnianie odporności emocjonalnej uczniów i nauczycieli w szybko zmieniającej się rzeczywistości, w celu zachowania zdrowia oraz ukształtowania umiejętności lepszego radzenia sobie w sytuacjach kryzysowych. Celem artykułu jest przedstawienie wyników części badań międzykulturowych dotyczących kompetencji w zakresie społeczno-emocjonalnego uczenia się (Social and Emotional Learning, SEL), polskich przyszłych nauczycieli pedagogiki przedszkolnej i wczesnoszkolnej. Główny problem badawczy ujęto w pytaniu: Z jakich kompetencji SEL, Twoim zdaniem, powinni korzystać nauczyciele, aby skutecznie uczyć swoich uczniów? Zastosowano podejście oparte na teorii ugruntowanej z wykorzystaniem oprogramowania NVivo do wspomaganej komputerowo analizy danych. Narzędzie badawcze stanowił kwestionariusz ankiety do badań jakościowych opracowany przez międzynarodową sieć badawczą CASEL (The Collaborative for Academic, Social, and Emotional Learning, casel.org). Przeprowadzone analizy dowiodły potrzeby, ale też możliwości systemowego rozwijania kompetencji zarówno intrapersonalnych, jak i interpersonalnych przyszłych nauczycieli w zakresie SEL jako podstawy nauczania tych umiejętności.
Nauczyciel – nieformalny przywódca edukacyjny. Style przywódcze a style kierowania zespołem klasowym preferowane przez nauczycieli edukacji wczesnoszkolnej szkół ogólnodostępnych i integracyjnych – komunikat z badań
Authors: Skibska Joanna
Published: June 2024

Nauczyciel jest nieformalnym przywódcą edukacyjnym, bowiem o jego roli decydują właściwości i efektywność działania. Jako lider planuje proces uczenia się i wyzwala w uczniach ich potencjał oraz wywiera wpływ i  uczestniczy w kształtowaniu relacji rówieśniczych. Celem badań było wskazanie stylów przywódczych preferowanych przez badanych nauczycieli edukacji wczesnoszkolnej oraz ich uwarunkowań a także zbadanie korelacji pomiędzy stylami przywódczymi a stylami kierowania zespołem klasowym preferowanymi przez badanych nauczycieli szkół ogólnodostępnych i integracyjnych.
Przeprowadzone badania wskazują, że nauczyciele edukacji wczesnoszkolnej zdecydowanie preferowali styl przywództwa autokratycznego, w którym lider – nauczyciel – nieformalny przywódca  skupia się przede wszystkim na zadaniu wykonywanym podczas zajęć i jego weryfikacji. Z kolei jeśli chodzi o style kierowania zespołem klasowym to badani nauczyciele szkół ogólnodostępnych preferowali perswadujący styl kierowania zespołem a nauczyciele szkół integracyjnych styl kierujący oraz uczestniczący.
To co wynika z przeprowadzonych badań to fakt, że badani nauczyciele edukacji wczesnoszkolnej bez względu na staż pracy, stopnień awansu zawodowego oraz rodzaj szkoły – ogólnodostępnej czy integracyjnej, przede wszystkim skupiali się na zadaniu, natomiast potrzeby uczniów nie były istotne w tym procesie. Zastanawia również pewna prawidłowość, że badani nauczyciele edukacji wczesnoszkolnej, którzy nie ukończyli studiów podyplomowych oraz kursów, warsztatów i szkoleń preferowali zintegrowany styl przywództwa, który w równym stopniu nastawiony jest na zadanie i ucznia, co było charakterystyczne dla badanych nauczycieli szkół integracyjnych.
W obu badanych grupach nauczycieli stwierdzono występowanie istotnej statystycznie zależności pomiędzy preferowanymi stylami przywództwa a stylami kierowania zespołem klasowym
