Serum brain-derived neurotrophic factor and macular perfusion in type 2 diabetes mellitus using optical coherence tomography angiography
Authors: Gamal El-Deen Asmaa Mohammed , Abd El-Hamid Samar Mohammed , Farrag Enas Ahmed
Published: March 2023

PURPOSE:

To investigate the relationship between serum brain-derived neurotrophic factor (BDNF) and changes in macular perfusion in different stages of diabetic retinopathy (DR) using optical coherence tomography angiography (OCTA).

MATERIALS AND METHODS:

The study was conducted on 72 eyes of people with type 2 diabetes mellitus (DM). They were divided into five groups based on their DR stage: no DR (nDR), mild and moderate nonproliferative DR, severe nonproliferative DR, active proliferative DR (aPDR), and stable PDR. The presence or absence of diabetic maculopathy was also used to categorize the cases. All patients underwent a complete history, ophthalmological examination, OCTA imaging, and evaluation of BDNF and glycated hemoglobin A1c levels.

RESULTS:

The mean blood BDNF levels in the aPDR group were considerably lower than those in the nDR group (P = 0.023). In comparison to eyes without maculopathy, eyes with maculopathy had considerably decreased mean blood BDNF levels (P = 0.0004). Comparing NPDR and PDR groups to nDR as well as NPDR and PDR, a substantial decrease in average and parafoveal vessel density (VD) of the retina and choriocapillaries was seen (P = 0.02). The Foveal Avascular Zone (FAZ) acircularity index and VD were found to be significantly impacted by deteriorating DR (P = 0.001 and 0.017, respectively). It was discovered that there is a positive correlation between BDNF and the FAZ fractal dimension (P = 0.03). In diabetic eyes, there was a statistically favorable correlation between BDNF levels and best corrected visual acuity (P = 0.002). Furthermore, there was a negative relationship between DM duration and BDNF (P = 0.021).

CONCLUSION:

Serum BDNF levels decreased with the progression of DR and in patients with maculopathy. BDNF was found to be related to macular perfusion, particularly in the fovea.

Published: March 2023

PurposeThe detection rate of early-stage lung cancer with ground-glass opacity (GGO) has increased, and stereotactic body radiotherapy (SBRT) has been suggested as an alternative to surgery in inoperable patients. However, reports on treatment results are limited. Therefore, we performed a retrospective study to investigate the clinical outcome after SBRT in patients with early-stage lung cancer with GGO-predominant tumor lesions at a single institution. Materials and MethodsThis study included 89 patients with 99 lesions who were treated with SBRT for lung cancer with GGO-predominant lesions that had a consolidation-to-tumor ratio of ≤0.5 at Asan Medical Center between July 2016 and July 2021. A median total dose of 56.0 Gy (range, 48.0–60.0) was delivered using 10.0–15.0 Gy per fraction. ResultsThe overall follow-up period for the study was median 33.0 months (range, 9.9 to 65.9 months). There was 100% local control with no recurrences in any of the 99 treated lesions. Three patients had regional recurrences outside of the radiation field, and three had distant metastasis. The 1-year, 3-year, and 5-year overall survival rates were 100.0%, 91.6%, and 82.8%, respectively. Univariate analysis revealed that advanced age and a low level of diffusing capacity of the lungs for carbon monoxide were significantly associated with overall survival. There were no patients with grade ≥3 toxicity. ConclusionSBRT is a safe and effective treatment for patients with GGO-predominant lung cancer lesions and is likely to be considered as an alternative to surgery.

Authors: Berecki Sándor , Gál Szilárd Sándor , Vaida Dan Lucian
Published: March 2023

In the Late Iron Age biritual cemetery from Fântânele-Dealul Iuşului / La Gâţa the remains of 43 individuals from 41 graves have been excavated to this day. The analysis of inhumation and cremation burials allowed for a paleodemographic study of this community settled on the fringes of the Celtic world. In addition to data on the sex and age or intravital body height of the deceased, pathological changes and epigenetic traits were also observed in some cases. Furthermore, analyses of the cremated human remains also brought to light different characteristics of burial habits, such as burning temperature or the rate of collection of the remains from the pyre.
Przeworsk tribes in the Western Ukrainian lands in the first centuries AD (according to the materials of funeral sites)
Authors: Vakulenko Liana V. , Didenko Serhiy V.
Published: March 2023

During the 1st-3rd centuries AD, waves of migrations repeatedly swept through the area of present-day western Ukraine. As evidenced by archaeological materials, migrations of Dacian and Przeworsk populations at the beginning of the 1st century AD and during the 2nd century led to the formation of the Lipitsa culture in this region, a cultural unit combining ethnic traits of both communities. Turbulent times of the Marcomannic Wars (166–180 AD) and a new wave of Przeworsk culture migration pushed the Lipitsa population out to Dacia. The distribution of archaeological sites from the late 2nd-3rd cent. AD shows that the Danube region was not the only direction of the Przeworsk tribes’ movement, as they also resettled and colonised new territories in the Volhynia, Podolia, and Polesia regions. Thus, the Przeworsk populations migrating to the western Ukraine in the first two centuries AD blended with the Dacian milieu, contributing to the creation of the Lipitsa culture. The Przeworsk populations of the second wave, which moved to the territory of Ukraine towards the end of the 2nd century and in the first half of the 3rd century AD, became the basis and a major component of a new cultural unit: the Chernyakhov culture of the Late Roman Period.
Blade from the Brona Pass
Authors: Mika Wojciech
Published: March 2023

Due to its landscape, dominated by hills reaching above 1000 m a.s.l., the southern part of the Western Beskids was long considered an area beyond the reach of prehistoric migrations. The small number of artefacts known from the area makes every new find significant. The article presents a stone artefact found on the Brona Pass in Beskid Żywiecki. It was made of a local raw material, quartzite sandstone. The discovery provides new evidence of the penetration of mountain landscapes by prehistoric communities.
“Tedious by Design.” Institutionalized Labor of Content Creators in the Game as a Service Model: The Path of Exile Case Study
Authors: Felczak Mateusz
Published: March 2023

This study investigates the work of content creators in relation to developers and fans, focusing on digital platforms in a case study of the video game Path of Exile which functions in the game as a service (GaaS) model. The analysis was based on in-depth, semi-structured interviews with a diverse group of aspiring content creators and on the assessment of data extracted from distribution, streaming, and social digital platforms. The institutionalized labor of content creators, which is subjugated to the live service model curated by the developers, could be characterized by the notions of transactional play, aspirational boredom, and gaming the markets. These three elements stand for the commodification of play time, substituting actual play with broadcasted footage, and actively shaping the in-game economy, respectively. The study acknowledges the rising importance of content creators as contributors to the financial well-being of a game employing the GaaS model, while raising awareness of the cultural, economic, ethical and health issues associated with it.
“Too Easy” or “Too Much”? (Re)imagining Protagonistic Enhancement through Machine Vision in Video Games
Authors: Solberg Ragnhild
Published: March 2023

This article explores how video games that valorize techno-masculine imaginaries of superhuman domination also present humans as depending on computational and non-human agencies to succeed. Through close readings of Call of Duty 4: Modern Warfare (Infinity Ward 2007) and Cyberpunk 2077 (CD Projekt Red 2020), I illustrate the close connection between machine vision and militarized visions of domination and agency. The analyses show how beyond-human vision enhances player characters and players, complicating the human-machine relationship in the process. Video games can build on and feed into anthropocentric and masculinist narratives. This article demonstrates how even when the technology appears to support these fantasies of human control, there are moments when it takes over or otherwise disrupts the god-like interventions of the human. By analyzing failures, glitches, and the consistent machine participation in the assemblage, I unpack explicit cases of machine agency as part of a broader assemblage, revealing a more complex power dynamics than those that are initially presented to the player. In doing so, this article demonstrates how the superhuman machine vision was never exclusively human to begin with. Understanding vision and agency as shared with machines both enables and complicates fantasies of dominance in video games.
Nowe media w strategiach komunikacyjnych polskich muzeów. Od Facebooka do TikToka
Authors: Gaweł Łukasz
Published: March 2023

New Media in Communication Strategies of Polish Museums. From Facebook to TikTok The changing world of digital media has had a huge impact on museum marketing strategies. To- day, it is virtually impossible to knowingly build the image of an institution without the use of social media. The analysis of the content posted on social media of Polish national museums will allow to define the nature of the relations built by these organizations with the social environment. However, another aspect of the presence of social media in museums is no less important: it is not only about information, marketing or image issues; social media are an important element of a consistent cre- ation of museums’ identity. A strong sense of self-identity is essential for museums not only to survive but also to thrive in an increasingly demanding world.
Frekwencja online – jak ją monitorować? Dotychczasowe praktyki publicznych muzeów w Polsce
Authors: Pluszyńska Anna

Monitoring of Online Audience. Previous Practices of Public Museums in Poland

A crisis situation – which the COVID-19 pandemic undoubtedly is – becomes an opportunity to shift the perspective and propose or even enforce new management solutions. The intensification of museum activities in the virtual world forces the need to ask again questions about audience segmentation, motivation and interaction (Noehrer et al. 2021). Although public cultural institutions (including museums) see the need for conducting audience research, in practice, they focus on counting attendance (Ćwikła et al. 2020). In addition, they are focusing on recipients visiting the buildings of the institution. Therefore, this article aims to answer the question of whether public museums in Poland monitor attendance during online events, on social media and on the website, and if so, what data are taken into account? Based on the interviews and questionnaires, I also tried to find out what are the difficulties in counting audience online. Finally, I make recommendations, including the need to create a measurement system in which different weights will be assigned to different types of audience engagement, including “active” indicators.
Cywilizacja jako proces część 2: Kryzys idei
Authors: Klimczyk Wojciech
Published: March 2023

Civilization as a Process: The Crisis of the Idea

The article presents the history of the notion of civilization at the stage of emerging civilizational pluralism. This presentation offers a critical reconstruction of civilizational essentialism, at least partially racist in character, which at the turn of the 20th century became the basic method for civilizational studies. In order to fully reveal the grounds upon which civilizational studies adopted “scientific” racism in the middle of the 19th century the text discusses the history of this research paradigm beginning from when the term “civilization” became prominent not only in moral but also historical and sociological analysis. On the one hand, this throws a clear light on the uncomfortable heritage of the discipline in terms of its mission to “civilize,” one that civilizational studies have faced until the present day. On the other, the article shows that the direction they chose in the times of social darwinism’s cultural triumph was not inevitable. In its shadow there have existed alternative civilizational studies with Norbert Elias as their early proponent. In order to develop them further one must not forget the history of the paradigm and hence this article is devoted to discovering the causes of the crisis in the colonial era of the Enlightenment idea of civilization, so important for Elias.

Weakly meet $s_{Z}$-continuity and $\delta_{Z}$-continuity
Authors: Hou Huijun , Li Qingguo
Published: March 2023

Based on the concept of weakly meet $s_{Z}$-continuouity put forward by Xu and Luo in \cite{qzm}, we further prove that if the subset system $Z$ satisfies certain conditions, a poset is $s_{Z}$-continuous if and only if it is weakly meet $s_{Z}$-continuous and $s_{Z}$-quasicontinuous, which improves a related result given by Ruan and Xu in \cite{sz}. Meanwhile, we provide a characterization for the poset to be weakly meet $s_{Z}$-continuous, that is, a poset with a lower hereditary $Z$-Scott topology is weakly meet $s_{Z}$-continuous if and only if it is locally weakly meet $s_{Z}$-continuous. In addition, we introduce a monad on the new category $\mathbf{POSET_{\delta}}$ and characterize its $Eilenberg$-$Moore$ algebras concretely.

One-step closure, weak one-step closure and meet continuity
Authors: Miao Hualin , Li Qingguo , Zhao Dongsheng
Published: March 2023

This paper studies the weak one-step closure and one-step closure properties concerning the structure of Scott closures. We deduce that every quasicontinuous domain has weak one-step closure and show that a quasicontinuous poset need not have weak one-step closure. We also constructed a non-continuous poset with one-step closure, which gives a negative answer to an open problem posed by Zou et al.. Finally, we investigate the relationship between weak one-step closure property and one-step closure property and prove that a poset has one-step closure if and only if it is meet continuous and has weak one-step closure.
The $d^{*}$-space
Authors: Chu Xiangping , Li Qingguo
Published: March 2023

In this paper, we introduce the concept of $d^{\ast}$-spaces. We find that strong $d$-spaces are $d^{\ast}$-spaces, but the converse does not hold. We give a characterization for a topological space to be a $d^{\ast}$-space. We prove that the retract of a $d^{\ast}$-space is a $d^{\ast}$-space. We obtain the result that for any $T_{0}$ space $X$ and $Y$, if the function space $TOP(X,Y)$ endowed with the Isbell topology is a $d^{\ast}$-space, then $Y$ is a $d^{\ast}$-space. We also show that for any $T_{0}$ space $X$, if the Smyth power space $Q_{v}(X)$ is a $d^{\ast}$-space, then $X$ is a $d^{\ast}$-space. Meanwhile, we give a counterexample to illustrate that conversely, for a $d^{\ast}$-space $X$, the Smyth power space $Q_{v}(X)$ may not be a $d^{\ast}$-space.

Representations of Domains via CF-approximation Spaces
Authors: Wu Guojun , Xu Luoshan
Published: March 2023

Representations of domains mean in a general way representing a domain as a suitable family endowed with set-inclusion order of some mathematical structures. In this paper, representations of domains via CF-approximation spaces are considered. Concepts of CF-approximation spaces and CF-closed sets are introduced. It is proved that the family of CF-closed sets in a CF-approximation space endowed with set-inclusion order is a continuous domain and that every continuous domain is isomorphic to the family of CF-closed sets of some CF-approximation space endowed with set-inclusion order. The concept of CF-approximable relations is introduced using a categorical approach, which later facilitates the proof that the category of CF-approximation spaces and CF-approximable relations is equivalent to that of continuous domains and Scott continuous maps.

Partial frames, their free frames and their congruence frames
Authors: Schauerte Anneliese , Frith John
Published: March 2023

The context of this work is that of partial frames; these are meet-semilattices where not all subsets need have joins. A selection function, S, specifies, for all meet-semilattices, certain subsets under consideration, which we call the ``designated'' ones; an S-frame then must have joins of (at least) all such subsets and binary meet must distribute over these. A small collection of axioms suffices to specify our selection functions; these axioms are sufficiently general to include as examples of partial frames, bounded distributive lattices, sigma-frames, kappa-frames and frames. We consider right and left adjoints of S-frame maps, as a prelude to the introduction of closed and open maps. Then we look at what might be an appropriate notion of Booleanness for partial frames. The obvious candidate is the condition that every element be complemented; this concept is indeed of interest, but we pose three further conditions which, in the frame setting, are all equivalent to it. However, in the context of partial frames, the four conditions are distinct. In investigating these, we make essential use of the free frame over a partial frame and the congruence frame of a partial frame. We compare congruences of a partial frame, technically called S-congruences, with the frame congruences of its free frame. We provide a natural transformation for the situation and also consider right adjoints of the frame maps in question. We characterize the case where the two congruence frames are isomorphic and provide examples which illuminate the possible different behaviour of the two. We conclude with a characterization of closedness and openness for the embedding of a partial frame into its free fame, and into its congruence frame.
PALM IDENTIFICATION

Published: March 2023

Multibiometrics can provide higher identification accuracy than single biometrics, so it is more suitable for some real-world personal identification applications that need high-standard security. Among various biometrics technologies, palmprint identification has received much attention because of its good performance. Combining the left and right palmprint images to perform multibiometrics is easy to implement and can obtain better results. However, previous studies did not explore this issue in depth. In this paper, we proposed a novel framework to perform multibiometrics by comprehensively combining the left and right palmprint images. This framework integrated three kinds of scores generated from the left and right palmprint images to perform matching score-level fusion. The first two kinds of scores were, respectively, generated from the left and right palmprint images and can be obtained by any palmprint identification method, whereas the third kind of score was obtained using a specialized algorithm proposed in this paper. As the proposed algorithm carefully takes the nature of the left and right palmprint images into account, it can properly exploit the similarity of the left and right palmprints of the same subject. Moreover, the proposed weighted fusion scheme allowed perfect identification performance to be obtained in comparison with previous palmprint identification methods.

Authors: Rupam Majumder  , Ahmed Hussain
Published: March 2023

The present study's goal was to identify measures and solutions in light of environmental information in corporate sustainability reporting practices in India. For this purpose, corporate sustainability report of 15 Indian Companies for the periods 2016-17 to 2019-2020 were checked and examined. 15 sample companies were selected following “Core &speaker; and Comprehensive Status” from the all-encompassing table of GRI as a pilot study. Based on disclosure check list of 32 environmental aspect parameter of GRI Standards 2016 and unweighted announcement index, the present study measures the consideration of GRI Standards revelation two together at the aggregate level and in respect of environment category of GRI standard. The result shows that in consideration of overall environment GRI Standard disclosures varies from 15.63% to 93.75%. The minimum revelation score of 15.63% is immeasurable. But the maximum announcement score is 93.75%. A mean disclosure score of 67.92% displays a comparatively moderate level of announcement. The study discloses a roomy alternative in consideration of environmental disclosure with range and standard deviation 78.13% and 22.66% respectively. On studies of research findings, the researcher concludes that there exists scope for improvement of environmental aspect reporting by Indian companies.

The set logistic parameters have a significant impact on industrial production, investment decisions and economic performance. The degree of detail also depends on the available information flows embedded in the batch production process from a logistical point of view. The established logistical parameters directly affect the flows themselves (material, personnel, information, technological, and waste disposal) along the entire production chain-from production to marketing- including their changing state in terms of technological features of the equipment and aggregates. It also affects the management and organizational structure.

The signal registration from distant objects is one of the major problems which concerns many scientists who work in the field of the space physics and the distant methods in the visible and the close infrared part of the optic spectre. For most of the systems which discover distant objects, a very small a priori probability for presence of a signal is characteristic and the a posteriori information becomes proportional to the likelihood ratio. To solve practical problems, the probability relation is conveniently presented by means of dividing the density to the discovery probability.

Significance of zinc deficiency correction for practical medicine: a review
Authors: Skalny A. V. , Sotnikova T. I. , Korobeynikova T. V. , Tinkov A. A.
Published: March 2023

Zinc deficiency is highly prevalent ranging from 10% to 30–40% of the population in developed and developing countries respectively. Low zinc level has been found to be associated with 0.7% of overall mortality and 1.0% of disability-adjusted life years (DALYs) worldwide. In turn, available research evidence has shown that zinc supplementation in its deficiency can reduce the risk of preterm birth, promote the physical development of children, and have certain protective effect against the components of the metabolic syndrome. A positive effect of zinc supplementation on recovery from pneumonia, diarrhea, and common cold has been reported. It is expected that the most pronounced effect of zinc supplementation may be observed in individuals with subclinical or severe zinc deficiency. Due to the high incidence of zinc deficiency, as well as its significant contribution to a wide range of pathologies, the correction of low zinc level may be considered as economically effective strategy. Thus, the results of the existing studies have demonstrated the efficiency of zinc intake for prophylaxis or as an adjuvant therapy of a wide range of pathologies.

Authors:   Tarakan Regional Hospital, Jakarta, Indonesia, Putri Hardianti , Yanuardani Melina Tiza ,   Tarakan Regional Hospital, Jakarta, Indonesia
Published: March 2023

Introduction: Burn patients deserve more attention because of their high morbidity and mortality rates. According to the World Health Organization, approximately 180.000 deaths per year are associated with burns. We aim to obtain the characteristics of burn patients at Tarakan Regional General Hospital Jakarta as a type A referral center hospital from 2018 to 2022 to examine patient trends, provide appropriate services for burn patients, and reduce the rate of poor quality of life caused by disability and death. Methods: A cross-sectional method with descriptive study was used. Medical records of patients with burns admitted to Tarakan regional general hospital Jakarta between January 2018 and September 2022 were evaluated. 191 burn patients were reviewed based on age, sex, total burn surface area, burn degrees, etiology, intervention, and discharge status. Results: The total number of burn patients at the Tarakan hospital Jakarta from 2018 - 2022 was 191, with an increase of 248% from 2018 to 2022. With a gender ratio of 1.03:1, 97 subjects were male, and 94 were female. Most patients have dominated with adults as much as 80.1%. The highest incidence of burns is due to gas explosions, with a total area of burn injury at 21-30% TBSA occurring at 40.84%, and most burns ensue in the second degree as much as 59.69%.

Tourism revenue is an important income component of the Turkish economy since the tourism revenue of Türkiye is ranked among the first fifteen countries in the World. Therefore, the analysis of the effects of tourism revenue of Türkiye on its economic stance is an active research area. This paper investigates the impact of the tourism revenue of Türkiye on the economic growth for the period of 2003-2022 using quarterly data. The causality relationship between the tourism revenue and the economic growth is ssanalysed as the first step employing the Granger causality tests. Then, the relative sensitivity of the economic growth dependent on the tourism income is computed in Python programming language. The result of the relative sensitivity analysis shows that the 1% increment in the tourism revenue leads to the 0.12% increment of the economic growth. The presented method can be applied for the analysis of the effect of the tourism revenue on the economic growth also for other countries.

Este estudo busca contribuir com a área de gestão analisando as relações de interação e cooperação entre os atores do APL de semijoias de Limeira/SP. O estudo se caracteriza como exploratório e descritivo utilizando as técnicas de entrevista semiestruturada junto ao órgão coordenador do APL e questionário para os diferentes atores, nas várias etapas do processo. Os resultados indicam que a cooperação e a interação entre os atores são de baixa intensidade, que por sua vez atuam em pequenos grupos de afinidades e não de forma ampla e sistêmica. Dentre os fatores que evidenciam esta atuação fragmentada, entre os atores, identifica-se a existência de forte concorrência e elevado nível de desconfiança entre as partes. No entanto, apesar destes fatores negativos, os atores reconhecem que a concentração, em uma localidade, de empresas que contemplam as etapas do processo de fabricação, possibilita ganhos operacionais e comerciais.
