Abstract
Purpose
Our objective was to quantitatively investigate metamorphopsia in patients who had undergone pars plana vitrectomy for rhegmatogenous retinal detachment at the Department of Ophthalmology of the University of Szeged. We aimed to compare our findings with perioperative clinical data, and in particular the patients' optical coherence tomography (OCT) results.
Materials/Methods
Our study is a retrospective analysis of data from 23 patients who had undergone surgery for retinal detachment. We evaluated best corrected visual acuity (BCVA), metamorphopsia (MM) using M-CHARTS, and macular morphological abnormalities using OCT images in patients who attended regular follow-up visits 1–6 months after the surgery.
Results
The mean preoperative BCVA of the patients was 0.4, while the mean postoperative BCVA was 0.6, indicating a significant improvement (P = 0.03). We observed a negative correlation between preoperative BCVA and postoperative MM (Pearson's r = −0.27), indicating that lower preoperative BCVA was associated with higher postoperative MM. Additionally, we noted a strong trend between disintegration of the ellipsoid zone (EZ), abnormality of the external limiting membrane (ELM), and MM (P = 0.051 and 0.072 respectively).
Conclusions
While no significant correlation was found between MM and specific perioperative factors, we observed a notable trend between EZ disintegrity and MM, as well as abnormal ELM and MM. This trend is anticipated to become significant with higher numbers of patients.

Csónak alakú fibulák Érd és Százhalombatta kora vaskori lelőhelyeiről
Abstract
The primary aim of this study is to present some Early Iron Age brooches found at Érd-Hosszúföldek, including an attempt to clarify some of the cultural connections of the area. The pair of boat-shaped fibulae connected by a chain, the three-footed vessels, and the ribbed cysts indicate a complex and widespread connection network in the period.
Abstract
The aim of our research is to fill the research gap on how successful businesses have been affected by the challenges posed by COVID-19 regarding the resilience and adaptability of firms. Since 2016, the Budapest Stock Exchange (BSE), with the collaboration of EY, selects a number of unlisted companies (BSE50) per year that have Hungarian roots and are considered successful based on their operations and ability to increase sales. We examined the impact of COVID-19 on profitability, liquidity, indebtedness and change in turnover or EBITDA based on four years (2018–2021) of financial data from 252 non-financial, unlisted companies. In addition to the descriptive statistics, a two-sample asymptotic z-test was used to compare the periods before and during COVID-19. We divided the BSE50 companies into Dynamics and Laggards based on the change in turnover between 2019 and 2020. The Dynamics of the pandemic have emerged from the challenging period of COVID-19 as real champions, taking advantage of their low level of indebtedness by making efficient use of loan possibilities. Even the Laggards were able to rebalance and consolidate their financial position by the second year of the pandemic. Our study is novel because we used data on Hungarian, non-financial, unlisted companies with successful management to examine the impact of COVID-19 on hard-hit firms as well as on firms in the winning branch.

A caricaturistic portrait of Ovid from Brigetio (Komárom/Szőny, Hungary)
Ovidius karikaturisztikus portréja Brigetióból (Komárom/Szőny)
Abstract
In 2015 a preventive excavation was carried out preceding the laying of an optical cable in close vicinity to the legionary fortress of Brigetio. An otherwise regular Roman terracotta roof tile was found during the excavation, with the image of a bearded man and the inscribed name of Ovidius Naso. The depiction of the poet leans more towards caricature rather than a realistic portrait, but since we do not know of any ancient representations of Ovid, it is of great importance and fits well into the series of other graffiti on roof tiles from Pannonia.
Abstract
In emerging economies, social entrepreneurship is becoming more widely recognized as a means of optimizing societal value. Examining the impact of emotional intelligence on students' intentions to pursue social entrepreneurship is the primary goal of this research project. The university students in Bangladesh were the study's target population. An online survey with self-administered questions was created to gather data from 334 Bangladeshi students. This study is exploratory and quantitative in nature. For this study purpose non-probability random sampling and convenience methods were applied to collect the data. Reliability was considered to be measured with a Cronbach's alpha (α) value of 0.70 or above. The study found the reliability of the constructs like self-awareness (α = 0.868), self-management (α = 0.895), social awareness (α = 0.867), relationship management (α = 0.948), and social entrepreneurial intention (0.864). The model was evaluated and the hypotheses were confirmed using SPSS v26.0 at the 5% significance level. Furthermore, this study's findings show 0.678 percent, or 67.8%, of the variance in Social Entrepreneurial Intention, which is valuable for the body of knowledge in this field of study. These findings could help academics, community organizations, non-governmental organizations, government, and civil society develop successful policies and initiatives to support students' plans to grow their social entrepreneurship in Bangladesh.
Abstract
Enterprises prioritizing social issues over profit maximization can lead to value co-creation, especially in marginalized and unprivileged communities. In this regard, this paper explores underlying theoretical mechanisms that tie digitalization and value co-creation together for social entrepreneurship's development. The article aims to identify how digitalization enables value co-creation for social enterprises. We conduct multiple case studies, have 11 in-depth face-to-face interviews with social entrepreneurs from Azerbaijan and synthesize the findings from primary and secondary data. As a result, we reveal that digitalization enables value co-creation for social entrepreneurship through a new phenomenon, which we call Data-driven Social Co-creation (DSC), and its subcategories such as efficiency, resource mobilization, feedback loops and data utilization. Finally, we recommend the DSC framework which shows the relationship between digitalization and value co-creation in social entrepreneurship, and which is the main theoretical contribution to the social entrepreneurship literature. Additionally, we provide a research agenda on the respective research field.
Abstract
Although the entrepreneurial gender gap is decreasing in European economies, the obstacles faced by women entrepreneurs remain numerous and often differ from those encountered by men. The COVID-19 pandemic, and then the energy crisis, have made it even harder for women entrepreneurs to sustain their businesses and have added to the challenges of work and private life. Women entrepreneurs, among many others, had to face how to survive crises and adjust their businesses to new circumstances to become more resilient, remain competitive and sustainable in times of crises, and in particular to improve their digital skills. A new insight is crucial for more efficient entrepreneurial development for women. A cross-country research helps to identify the needs of women entrepreneurs and provide a solid basis for the development of tailor-made activities focusing on innovative and practical solutions to support the up-skilling and resilience of women entrepreneurs. Through a survey conducted with 608 women entrepreneurs from seven European countries, our basic question was how women entrepreneurs managed to get through and become resilient in times of crises. The focus of our analysis is digitalization: did the rapid digital transition help women entrepreneurs become resilient during turbulent times? Did the practicing of digitalization-based resilience strategies (including remote work, online sales and similar approaches) improve women entrepreneurs' operational efficiency and strength?
Ein Hortfund aus der Koszider-Periode im Bükk Gebirge
Mittelbronzezeitliche Metallfunde von Dédestapolcsány-Verebce-bérc
A bronze hoard from the Koszider period in the Bükk Mountains: Middle Bronze Age metal finds from Dédestapolcsány-Verebce-bérc
Absztrakt
A tanulmány Dédestapolcsány-Verebce-bérc lelőhelyen az elmúlt évek intenzív kutatásai során előkerült középső bronzkor végi bronztárgyakat ismerteti, és ezek tükrében támpontokat ad a Bükk hegység középső bronzkori használatát illetően. 2022-ben négy gombos végű bronzsarlóból álló koszideri korú depó került elő fémkeresős lelőhely-felderítés során, és feltehetően ehhez az együtteshez tartozott egy szórványként talált sarkított peremesbalta is. A lelőhelyről két további szórványlelet, egy peremesbalta és egy spiráltekercsben végződő karperec töredéke ismert még ebből a korszakból.
Abstract
This study analyzed the impact of storing Golden Delicious apples at 3 °C with a relative humidity of 85 ± 5% in two environments, namely a darkroom (D03) and a lightroom (L03), on the fruit quality. The research evaluated weight loss (Δm) and color metrics (a*, b*, L*, ΔE, C*, hue angle). The number of apples used for each storage was 12. Weight loss was calculated by measuring the changes in mass during storage. Color differences (ΔE), chroma (C*), and hue angle were determined based on the L*a*b* scale values. Apples stored at 3 °C in D03 experienced a minimal percentage of weight loss of 7.02%. The results indicated that compared to the D03 storage, the L03 storage had a more significant increase in Δm and color variation. The non-destructive method of measuring color characteristics facilitates the assessment of the storage conditions for Golden Delicious apples.
