Authors: Kanagasabai Lenin
Published: September 2024

In this paper Atlantic blue marlin (ABM) optimization algorithm, Boops optimization (BO) algorithm, Chironex fleckeri Search Optimization (CSO) algorithm, General practitioner -Sick person (PS) optimization algorithm are applied for solving factual power loss reduction problem. The regular actions of Atlantic blue marlin are emulated to design the Atlantic blue marlin (ABM) optimization algorithm and populace in the examination space is capriciously stimulated.  Boops optimization (BO) algorithm is designed by imitating the actions of Boops. Boops possess the obliging stalking physiognomies. As a cluster they stalk the quarry by forming the key and subordinate clusters CSO is based on the drive and search behaviour of Chironex fleckeri.  Obviously Chironex fleckeri will exploit the limbs to paralyze the pray by injecting the rancour. In real time world a General practitioner will treat the Sick person with various procedures and it has been imitated to model the Projected PS algorithm.  In general people will be inoculated and then with respect to disorder and disease- medical treatment will be given by medicines. Inoculation, medicine and operation are the procedures have been considered as the phases of the projected PS algorithm.  Atlantic blue marlin (ABM) optimization algorithm, Boops optimization (BO) algorithm, Chironex fleckeri Search Optimization (CSO) algorithm, General practitioner -Sick person (PS) optimization algorithm validated in IEEE 57, 300 systems and 220 KV network.  Factual power loss lessening, power divergence restraining, and power constancy index amplification has been attained.

Authors: Wulandari Sri , Formen Ali
Published: September 2024

This study investigates the implementation of Integrative Holistic Early Childhood Development (IHECD) in Mimika Baru Sub-district, focusing on four kindergartens: TK Negeri 1 Mimika, TK Kartika VI-31, TK Advent Timika, and TK Ceria Cerdas. Utilizing IFAS (Internal Strategic Factor Analysis Summary) and EFAS (External Strategic Factor Analysis Summary), the research aims to evaluate the current conditions and recommend strategies for optimizing IHECD. An evaluative study method was employed, involving questionnaires and focus group discussions to gather data on internal factors such as leadership, educator quality, and infrastructure, as well as external factors including government support and community involvement. The findings reveal that all institutions have more strengths than weaknesses and more opportunities than threats, placing them in quadrant I of the SWOT matrix, which indicates strong positions with significant growth potential. Despite these strengths, challenges such as inadequate infrastructure and insufficient health and safety measures were identified. The study underscores the need for tailored strategies to address these issues, suggesting that policymakers and stakeholders enhance support and resources to improve IHECD implementation. By focusing on strengthening internal capabilities and leveraging external opportunities, the overall quality of early childhood development services can be elevated, contributing to better educational outcomes and human resource development in the region. Furthermore, the research recommends a growth strategy for these institutions to maximize their strengths and opportunities. Future research should explore diverse settings, including rural areas, and consider longitudinal approaches to assess the long-term impact of recommended strategies. This comprehensive approach will ensure that all children in the Mimika Baru Sub-district have access to quality early childhood development services.
Understanding Anxiety among Students Who Memorize the Qur'an
Authors: Naufalita Naufalita , Sari Ratna
Published: September 2024

Anxiety may be experienced by all groups, including students who memorize the Qur’an.  This research aims to explore the types of anxiety experienced by students who memorize the Qur'an, identify the factors that contribute to it, and examine the efforts made by supervisors to address it. The study used a qualitative approach, with data collected through observation and interviews, and analyzed using the Miles and Huberman model. The results showed that students experienced both reality-based and moral-based anxiety. Environmental factors were found to contribute to anxiety, and institutional support was found to be lacking. While the vice principal made no efforts to address anxiety among students, the tahfiz extracurricular participants used self-control, asking for help, and muroja’ah as strategies to cope. This study identifies several types of anxiety and variables that contribute to it while emphasizing the importance of institutional support in resolving mental health issues. Practical consequences of this research include the development of customized treatments for students, training for educators on identifying anxiety and establishing extensive support systems within educational institutions.

Consent and Resistance: Indonesian Corona-Inspired Islamic Music in the Wake of the COVID-19 Pandemic
Authors: Lestari Febriyanti
Published: September 2024

The COVID-19 pandemic sparked the production of corona-inspired Islamic music in Indonesia. Interestingly, against the backdrop of chaos and uncertainty, the genre appears to have transcended mere value-added entertainment and can be viewed as a tool that operates with or against power. Using Stuart Hall's concept of culture and power, this study aims to examine how popular culture such as this is utilized by the elites and the ordinary. This is qualitative research using content analysis, and the data were taken from the lyrics and live performances of Bimbo with their song “Corona” and Audul Marom rebana group with “Sirahku Mumet Sirahmu Piye.” This research found that corona-inspired Islamic music is not just an aesthetic call to surrender to God in the face of crisis. Instead, it acts as a vehicle for cultural adaptation by authorities and a platform for expressing dissent among the ordinary. Bimbo’s “Corona” and its involvement in the government-sponsored fundraising concerts exemplify efforts to mitigate public distrust during the pandemic. In contrast, the “Sirahku Mumet Sirahmu Piye” reproduced and popularized by a local rebana group from Demak echoes the plight of the lower classes, articulating the economic burden of the commoners due to COVID-19 measures.

El narcopopulismo como élite ilegal, pero legítima, en América Latina
Authors: Wilches Tinjacá Jaime Andrés , Guerrero Sierra Hugo Fernando , Salamanca López Mario Esteban
Published: September 2024

El populismo ha sido identificado como un discurso influyente en la reconfiguración de la división élites vs. pueblo en América Latina. No obstante, el ascenso de expresiones populistas también ha significado la emulación de dichas prácticas en organizaciones narcotraficantes (narcopopulismo) que aprovechan su presencia en territorios mediados por violencia, inequidad y corrupción estatal. El objetivo del artículo es identificar los programas narrativos del narcopopulismo para afianzarse como un referente elitario para competir con populistas. El método de investigación se trabaja desde la semiótica del discurso político y la construcción de cuatro programas narrativos que se sustentan en un corpus de 116 discursos populistas y 113 narcopopulistas. Los resultados muestran que populistas y narcopopulistas disponen de repertorios discursivos para enfrentar escenarios de confrontación de sus objetivos, con inclinación hacia acuerdos implícitos y de cooperación en los que no se atacan intereses del contradictor, pues supone un gasto de recursos económicos, humanos y logísticos que ponen en riesgo la legitimidad de los programas narrativos en los sectores poblacionales donde tienen influencia. La discusión sugiere que populistas y narcopopulistas terminan convertidos en élites emergentes que luchan por representar la desconfianza social frente al sistema económico y político, y de ahí que se derive la necesidad de reformular categorías para el análisis de élites en América Latina.
Producing Knowledge for Socio-Ecological Transformation in Central Asia? A Humbling Experiment in Re-Cognizing Rivers
Authors: Féaux de la Croix Jeanne
Published: September 2024

As the deepening climate crisis shows, our greatest scientific challenge is to turn abstract understanding into doing. This means that the classic divide in research between ‘basic’, ‘applied’ and ‘outreach’ phases no longer adequately serve the need for transformative social learning. What can this kind of transformation look like in a world region such as Central Asia, with its own distinct legacies of environmental and social flourishing and suffering? What are the consequences of Central Asia’s particular forms of structural opportunity and violence around knowledge-creation? This paper discusses transdisciplinary research models in light of real collaborations on the banks of the Naryn and Syr Darya rivers. I examine the strengths and weaknesses of research with a wide range of actors in Central Asia such as irrigation specialists, artists and social scientist. Drawing on this experience, the paper analyses how broad regional trends in activism and scholarship intersect with global developments in knowledge-production methods and economies.
Structural detachment influences the shale gas preservation in the Wufeng-Longmaxi Formation, Northern Guizhou Province
Authors: Shi Sheng , Wang Ganlu , Mou Yuliang , Wei Xiangfeng
Published: September 2024

In order to reveal the restriction in shale gas enrichment of the Wufeng-Longmaxi Formation in the northern Guizhou province, the influence model of detachment layer was established through field geological investigation, core observation, logging, sample analysis, and geological background data. The response relationship between the detachment layer and the shale gas enrichment model in different structural formats was analyzed. The results show that the thickness of the Wufeng-Longmaxi Formation’s detachment layer is influenced by the conditions near the fault zones and mineralogical characteristics. The lithofacies of the detachment layer shows mainly a combination of clay-rich shale facies. This indicates that lithofacies type is one of the main factors influencing the variation in slip layer thickness. The detachment layer exhibits distinct well logging response characteristics and is influenced by nitrogen enrichment. The development of detachment fractures allows atmospheric nitrogen to infiltrate shale gas. It leads to poor gas saturation in the shale gas. In addition, the overall tectonic deformation in the northern Guizhou province was found to gradually intensify from Northwest to Southeast, and there were two tectonic models: a slot-shift tape transition belt and a spacer type deformation belt. The influence of decollements on shale gas preservation was barely found in the northern Guizhou province. It is mainly controlled by buried depth of the target layer, conditions of the cover layer, structural type, and deformation intensity.
Geospatial modeling of wildfire susceptibility on a national scale in Montenegro: A comparative evaluation of F-AHP and FR methodologies

Published: September 2024

Wildfires pose a significant ecological, environmental, and socioeconomic challenge in southeastern Europe. The preservation of wildlands is not only essential but also a foremost priority for Montenegro, a country recognized as the world’s first ecological state. Consequently, the development of optimal methodologies and models is of paramount importance to enhance fire protection measures. With this objective in mind, this study strives to create a wildfire susceptibility model on a national scale for Montenegro. The study employed seven natural and anthropogenic causative criteria: vegetation type; aspect; slope; elevation; climate classification; distance from road; and population. The modeling process integrates both natural and anthropogenic causal criteria, employing the Fuzzy Analytic Hierarchy Process (F-AHP) and Frequency Ratio (FR) within geoinformatics environment. The outcomes of the F-AHP model reveal that 72.84% of the total area is categorized as having high to very high susceptibility. Conversely, based on the FR model, only 29.07% of the area falls within these susceptibility levels. In terms of validation, the area under curvature values indicates good performance of the F-AHP model. In contrast, the FR model demonstrates poor performance. These novel findings, pertaining to Montenegro at a national scale, offer valuable insights for preemptive wildfire safeguarding efforts. Moreover, the methodologies employed, with necessary modifications, hold potential for application in geographically diverse regions.

Bildsamkeit, Vervollkommnung und Optimierung
Authors: Dederich Markus , Zirfas Jörg
Published: September 2024

Historisch erscheint die Umstellung der Semantik von Vollkommenheit als Optimum menschlicher Entwicklung auf Perfektionierung bzw. Vervollkommnung im 16. und 17. Jahrhundert bedeutsam. Infolgedessen wurde die Vervollkommnung von der (absoluten) Vollkommenheit gelöst bzw. die Vollkommenheit selbst als entwicklungsfähig bzw. steigerbar angesehen. Wenn in den aktuellen Debatten weder von einer Vollkommenheit des Menschen noch von seiner Vollendung die Rede ist, ist das auch ein Indiz dafür, dass ein integrales Ziel menschlichen Lebens nicht mehr vorstellbar erscheint. Genau dieser Verlust macht die Figur der Optimierung attraktiv, bietet diese doch eine irgendwie geartete Orientierung. Zwei pädagogische Grundbegriffe sind mit dieser Orientierung verbunden: Bildsamkeit und Vervollkommnung. Bildsamkeit kann ganz allgemein als eine dem Menschen zugeschriebene Fähigkeit verstanden werden, Fähigkeiten auszubilden und zu entwickeln, zu lernen und sich mit pädagogischer Unterstützung und im Austausch mit der natürlichen, sozialen und kulturellen Welt zu bilden. Auf der anderen Seite verweist der Begriff der Vervollkommnungsfähigkeit darauf, dass das Konzept der Bildsamkeit mit einem Telos versehen werden muss, auf das diese hin entwickelt werden soll. Unter den Bedingungen der Moderne geraten Bildsamkeit und Vervollkommnung in den Sog eines entgrenzten Optimierungsmodells, das in seinen extremen Spielarten über den Menschen hinausweist.
A Subcortical Model for Auditory Forward Masking with Efferent Control of Cochlear Gain
Authors: Maxwell Braden N. , Farhadi Afagh , Brennan Marc A. , Svec Adam , Carney Laurel H.
Published: September 2024

Previous physiological and psychophysical studies have explored whether feedback to the cochlea from the efferent system influences forward masking. The present work proposes that the limited growth-of-masking (GOM) observed in auditory nerve (AN) fibers may have been misunderstood; namely, that this limitation may be due to the influence of anesthesia on the efferent system. Building on the premise that the unanesthetized AN may exhibit GOM similar to more central nuclei, the present computational modeling study demonstrates that feedback from the medial olivocochlear (MOC) efferents may contribute to GOM observed physiologically in onset-type neurons in both the cochlear nucleus and inferior colliculus (IC). Additionally, the computational model of MOC efferents used here generates a decrease in masking with longer masker-signal delays similar to that observed in IC physiology and in psychophysical studies. An advantage of this explanation over alternative physiological explanations (e.g., that forward masking requires inhibition from the superior paraolivary nucleus) is that this theory can explain forward masking observed in the brainstem, early in the ascending pathway. For explaining psychoacoustic results, one strength of this model is that it can account for the lack of elevation in thresholds observed when masker level is randomly varied from interval-to-interval, a result that is difficult to explain using the conventional temporal window model of psychophysical forward masking. Future directions for evaluating the efferent mechanism as a contributing mechanism for psychoacoustic results are discussed.

Çalışmamızda Afyonkarahisar’da rastgele 20 farklı marketten alınan fındık örnekleri aflatoksin B1 (AFB1), aflatoksin B2 (AFB2), aflatoksin G1 (AFG1), aflatoksin G2 (AFG2, toplam aflatoksin (AF) ve okratoksin A (OTA) içerikleri bakımından Yüksek Performanslı Sıvı Kromotografisi (HPLC) ile incelenmiştir. Ayrıca örneklerdeki fungal kontaminasyonu belirlemek amacıyla, fungus izolasyonu yapılarak genus seviyesinde sınıflandırılmaları gerçekleştirilmiştir. Elde edilen sonuçlara göre iki lokalite dışında kalan tüm bölgelerdeki fındık örneklerinden fungus izole edilmiştir. Aflatoksin taramalarında merkez 5. örneklem alanında 1.8070 ng/ml AFG1 en yüksek aflatoksin miktarı olarak bulunmuştur. Elde edilen veriler değerlendirildiğinde tespit edilen aflatoksin miktarları Türk Gıda Kodeksi sınırlarını aşmamıştır. Dolayısıyla yapılan çalışma ile fındık örneklerinde yüksek potansiyel bir risk tespit edilmemiştir. Ancak potansiyel risk değerlendirmesinin yapılabilmesi için; az miktarlarda aflatoksin ve okratoksin varlığının çeşitli gıdalarla vücuda alınarak uzun vadede karaciğerde birikme ihtimali açısından da değerlendirilmesi gerekmekte olup, bu çalışma ileri çalışmalar için bir temel oluşturmaktadır. Ayrıca daha önce bu konuda Afyonkarahisar’da yapılmış herhangi bir çalışma bulunmamaktadır.
Internationale Handelskonflikte: eine verhaltensökonomische Analyse

Globale Handelskonflikte erschweren den Außenhandel und werden von Staaten zur Durchsetzung ihrer wirtschaftspolitischen Interessen genutzt. Für exportorientierte Volkswirtschaften wie Deutschland ist dieses Verhalten besonders schädlich. Die Europäische Union reagiert darauf mit einer sogenannten De-Risking-Strategie, die protektionistisches Verhalten sanktioniert. Dieser Beitrag untersucht die Auswirkungen dieser Strategie aus einer verhaltensökonomischen Perspektive.

Ramírez Luengo, José Luis y García Aranda, María Ángeles (2023). Construyendo la lengua de hoy: nuevos estudios sobre el español del siglo XIX. Madrid: Visor Libros
Authors: Kosteva Kristina
Published: September 2024

Los estudios diacrónicos sobre la lengua española cuentan con épocas bien estudiadas —sobre las que existe una abundante bibliografía, como es el caso del Siglo de Oro— y otros períodos que son desatendidos por los investigadores. Una escasez que va acrecentándose sobre todo si nos acercamos al español moderno o contemporáneo (Buzek y Šinková, 2015, p. 7). A este respecto, un caso prototípico es el siglo xix, que —con la excepción de algunos acercamientos al léxico y otros muy parciales a la historia externa— constituye todavía un auténtico hueco en blanco sobre el que queda mucho por investigar (Ramírez Luengo, 2012, p. 7).

Insulin resistance is thought to be a key pathophysiologic indicator underlying type 2 diabetes mellitus. Nevertheless, its pathophysiology is complex and remains uncertain. Myokines such as myonectin and irisin produced by muscle tissue were shown to impact the sensitivity to insulin and could play an essential role in the etiology of insulin resistance. Apelin and Elabela are endogenous peptide ligands of the angiotensin II protein J receptor (APJ) that are actively involved in the control of lipid and glucose metabolism, implying a vital role in the management of metabolic conditions like type 2 diabetes. In this review, the data on the level of myonectin, irisin, apelin-13 and Elabela in patients with type 2 diabetes mellitus were analyzed. Keywords: apelin-13, Elabela, insulin resistance, irisin, myonectin, type 2 diabetes mellitus

Sex hormones play a leading role in the sexual dimorphism of mitochondrial dysfunction and oxidative stress that are associated with Metabolic Syndrome (MetS) and considered as possible causes of cardiovascular disease. The aim of the work was to determine mitochondrial respiration and redox homeostasis in the heart mitochondria of high-fructose diet-fed (НFD) rats depending on sex. MetS was induced in Wistar rats by 8 weeks intake of fructose (200 g/l) with drinking water. The experiment was performed on 30 rats divided into five groups: control males, control females, HFD-fed males, HFD- fed females with intact ovaries, ovariectomized HFD-fed females. Heart mitochondria were isolated and indicators of redox homeostasis as well as mitochondrial oxygen consumption rate were determined. Heart mitochondria of intact female rats were characterized by a lower intensity of lipid peroxidation, a higher activity of antioxidant defense system and state 3 respiration in comparison with control males. HFD was shown to induce more expressed oxidative stress due to significant inhibition of enzymatic and non-enzymatic components of antioxidant defese and more pronounced dysregulation of mitochondrial respiration in the heart mitochondria of ovariectomized females as compared to males. This data may partially explain the greater cardiovascular risk in women with low estrogen sufficiency and justify the necessity of new sex-specific prevention and treatment of cardiovascular risk approaches. Keywords: antioxidant defense system, heart mitochondria, mitochondrial respiration, oxidative stress, rats, sex differences

Spexin (SPX) is a newly discovered brain adipokine implicated in various homeostatic functions including metabolism, energy balance, endocrine processes and growth hormone (GH) production in particular. At the same time, the growth-promoting effects of GH are influenced by Insulin-like growth factor-1 (IGF‑1) and vitamin D3. The aim of this study was to investigate the possible involvement of SPX in growth hormone deficiency (GHD) in children. The research involved 90 children (40 with growth hormone deficiency and 50 healthy controls aged 5-14). Serum levels of GH, IGF and vitamin D3 were tested using a chemiluminescent immunoassay, that of SPX – by Elabscience ELISA Kit. The results revealed that children with GHD had significantly higher SPX levels compared to the control group. No significant difference in IGF-1 and vitamin D3 levels between patients and control groups was observed. In the GHD group, we found a significant negative correlation between SPX and GH levels; at the same time, there was no correlation between SPX and D3 levels. These findings suggest that the changes in SPX levels may contribute to growth hormone deficiency. Keywords: growth hormone deficiency, IGf-1, Iraqi children, spexin, vitamin D3

Calixarenes are macrocyclic compounds, the biochemical effects of which are actively studied. In this study we synthesized thiacalix[4]arene chalcone amides С-1191 and С-1192, which have a sulfur atom in their structure and different spatial arrangement of chalcone amide groups, and studied their effect on myometrium functioning. Experiments were conducted with the use of rat uterine smooth muscles preparations, isolated myometrial mitochondria and permeabilized myometrial cells. The relative value of mitochondria membrane potential (Δψ) was assayed with a voltage-sensitive fluorescent probe TMRM. The spontaneous contractive activity was studied by tenzometric method followed by mechanokinetic analysis. It was shown that C-1191 and C-1192 induced mitochondria hyperpolarization and increased the basal tension of myometrium smooth muscle preparation. Thiacalix[4]arene С-1191 did not change the uterine cycle, but increased the force, velocity and impulse parameters of muscle contractive activity. On the contrary, С-1192 modified the uterine cycle considerably, increased the total efficiency of the myometrium spontaneous contractive activity and decreased the force, time and impulse parameters. It is concluded that changes in the mechanokinetic parameters of myometrial contractile activity induced by С-1191 and С-1192 are determined by the functional activity of mitochondria.

The micro- and macromorphological characteristics of seeds of species of the genera Spergula and Spergularia in the flora of Ukraine were studied in order to identify new diagnostic characters useful for solving taxonomic issues. The ultrastructure of the seed surface was studied using a scanning electron microscope. Seeds of some species of these genera are similar in appearance (especially with a wide wing — Spergula morisonii and Spergularia marina), which can be one of the confirmations of the close taxonomic affinity of these genera. The results of our study showed that the ultrastructure patterns of the surface of seeds of Spergula and Spergularia species differ among themselves within these genera but for some species can be used as diagnostic characters for their identification. The data obtained confirm the results of our previous research on the taxonomic status of some representatives of the studied taxa (Fedoronchuk, 2023). In particular, taking into account the similarity of seed ultrastructure and other characteristics that have been proposed previously, we consider Spergula vulgaris a synonym of Spergula arvensis subsp. arvensis, S. vernalis — a synonym of S. morisonii, Spergularia media — a synonym of Spergularia marina, and Spergularia salina — a synonym of Spergularia marina. Differences in the surface ultrastructure of Spergula sativa and Spergula arvensis subsp. arvensis, which is consistent with our understanding of the taxon (Fedoronchuk, 2023) as Spergula arvensis subsp. sativa, as well as between Spergula maxima and Spergula arvensis subsp. arvensis, accordingly we propose — Spergula arvensis subsp. maxima. Compiled descriptions of the surface ultrastructure of seeds of Spergula and Spergularia species collected in the territory of Ukraine can be used as a model for assessing the possible variability of the morphological characters of these species in other regions of the world.

A Birodalom visszavág – A természetben bekövetkező egyes változások hatása a turizmusra
Authors: Péter Erzsébet , Kaszás Nikoletta , Németh Kornél
Published: September 2024

Az ökoturizmus egyensúlyának fenntartása lényeges, többek között azon kérdések megválaszolásában, hogy vajon síelhetnek-e még az unokáink, és meddig láthatunk ép korallzátonyokat, vagy élvezhetjük egy közeli erdő békés nyugalmát. A fogyasztók mértékletességgel vagy időszakos lezárásokkal adhatnak időt a természetnek a megújulásra. Jelen cikk másodlagos adatelemzéssel arra keresi a választ, hogyan reagál a környezet a nemzetközi és a hazai turizmusra, milyen lépéseket tehet az ember, hogy a biodiverzitás helyreálljon, valamint a természeti folyamatok milyen hatással vannak a természetet fogyasztó turizmusra. A turista döntése általában összetett információelemzési és értékelési folyamat eredménye. A szabadidős turizmus bizonyos szegmenseiben az utazás bekövetkeztét és célját meghatározhatják olyan „last minute” tényezők, mint a pillanatnyi időjárás vagy az elkövetkező néhány napra vonatkozó meteorológiai előrejelzés. A klíma mint külső tényező globális változása alapvetően átalakíthatja a nemzetközi turisztikai piac keresleti és kínálati jellemzőit. A turizmus egyszerre okozója és elszenvedője a természetben bekövetkező változásoknak. Az ember által előidézett negatív externáliákra a természet is reagál, helyenként visszavág – éghajlati és domborzati változásokkal, járványokkal, természeti katasztrófákkal, illetve az állat- és növényvilág átrendeződésével, amelyek átrajzolják a turisztikai térképeket is.
A környezetvédelmi jogi normák és a zöldre festés a turizmusban – A greenwashing jelenség és szabályozási háttere
Authors: Kundi Viktória , Ernszt Ildikó
Published: September 2024

A környezet védelme mind a vállalkozások, mind a fogyasztók számára központi jelentőségű kérdéssé vált. Így napjainkban a vállalati kommunikáció egyik fontos eleme, hogy felhívják a figyelmet termékeik, szolgáltatásaik készítésének környezetet óvó, fenntartható aspektusaira. A vállalatok azonban profitorientáltak, céljuk a fogyasztók megnyerése, és nem riadnak vissza attól, hogy zöldbe burkolt, sokszor teljesen üres frázisokat segítségül hívva tegyenek szert több utasra, nagyobb bevételre.

Cikkünk célja, hogy bemutassa ezt a jelenséget a turizmus területén, és rávilágítson a „zöldre festés” szabályozási hátterének nehézségeire, miközben rövid áttekintést is adunk a környezetvédelmi tárgyú normák és kezdeményezések tekintetében.
Környezetbiztonsági kihívások a városi turizmusban

Published: September 2024

A városok szerepe kiemelkedő mind a kultúra, mind a gazdasági élet és a népesség koncentrációjának szempontjából, és egy város mint lakóhely, munkahely, szolgáltatási központ, közlekedési csomópont, befektetési célpont, rendezvényhelyszín és mint desztináció különösen érdekes a környezetbiztonság szemszögéből is. A városi turizmus vendégköre sokrétű, az üzleti utazók és a kulturális turisták mellett a barát- és rokonlátogatások, valamint a helyi lakosság általi szabadidős fogyasztás is jellemző. A városi desztinációk népszerűségének növekedésével a túlturizmus környezetre és életminőségre gyakorolt negatív hatásai is megjelenhetnek. Jelen tanulmány a városi turizmus sajátos környezetbiztonsági aspektusait, kihívásait és jó gyakorlatait vizsgálja hazai és nemzetközi példákon keresztül.
Back to the Wild Frontier(s): Osek, Waṅhal and the Nature of the 18th-Century Music Catalog
Authors: Hosar Halvor K.
Published: September 2024

The sizeable music collection from the Osek monastery has previously been interpreted in light of a catalog that was updated 1754–c1802. The completion of a modern catalog allows for a reappraisal of the history of the institution. Previous research has explained the lack of updates in the catalog during the years 1778–1802 with a decline in musical activity following the reforms of Joseph II. The collection, however, suggests that Jan Jakob Trautzl, regens chori since 1783, began his tenure by acquiring sacred works by Johann Baptist Waṅhal which rank among the largest and most ambitious from the era. There is also evidence of local adaptations of masses into polychoral and polyorchestral arrangements. Except for a possible low point during the years 1787–1789, the reforms thus seem to have had limited effect. The failure to accurately represent the collection in the catalog suggests the necessity for a new paradigm for reading such documents. One may preliminarily consider catalogs' limited potential for additions and emendations and understand them as tools for music professionals rather than librarians. In this view there is nothing surprising about lacunae, but the inclusion of a work becomes a sign of intent from the cataloger.
Instrumentale Melodieanfänge und ihr Verhältnis zur Form am Beispiel historischer und gegenwärtiger ungarischer Tanzmelodien
Authors: Tari Lujza
Published: September 2024

The aim of this study is to analyze the beginning of different dance tunes in connection with variously performed dance tunes. The purpose of this paper is also to draw attention to the need for micro-analysis, which has been neglected for a long time in instrumental folk music research, in order to better understand instrumental musical melody creation. The selected musical examples come from different (partly historical) eras and different geographical areas of Western Transdanubian and Transylvanian Hungarian folk music collections. Typical starting elements (fifth-forth changes, direction of moving of scales, etc.) are related to dance music with different names. The analysis ignores the evolution of tempo and variation throughout the piece, as well as the ensemble's “Primas” ornamentation, timbre, harmonies and unique solutions of the accompaniment. At the same time, the author paid attention to the form and structure of the entire piece in addition to the beginnings of the melody. The study was written in honor of the 100th birthday of Walter Deutsch, the creator of modern Austrian ethnomusicology.

OBJECTIVE: To report an adolescent patient who was diagnosed with Acute lymphoblastic leukemia (ALL) after completing Ewing sarcoma (ES) therapy.
CASE: A 14 years old girl complained of left crusis tumor since 4 months before hospitalized. Tumor biopsy showed a round cell tumor, as well as immunohistochemistry which showed a positive CD99, consistent with ES. The patient had received 14 cycles chemotherapy for 7 months with regimens vincristine 1.5 mg/m2, cyclophosfamide 1200 mg/m2, dactinomycin 0.5 mg/m2, and doxorubicin 30 mg/m2. Between chemotherapy, patient also was given granulocyte colony-stimulating factor several times. Pasien also undergo 31 times radiation therapy with total 31x1.8 Gy (55.8 Gy). Two months after last chemotherapy for Ewing sarcoma, she was admitted again with prolonged fever, and pallor.Laboratorium showed leukocytosis (88.86x103uL), monocytosis (41%), severe neutropenia (0.39x103uL), severe normochromic normocytic anemia (4,3 g/dL), severe thrombocytopenia (4x103uL), reticulocytopenia (0,46%), with lymphoblast in peripheral blood smear. Bone marrow aspiration result showed lymphoblast infiltration 60% with heterogen morphology, no cluster cell non hematopoetic in bone marrow, consisten with acute lymphoblastic leukemia (ALL-L2) suspected secondary malignancy from Ewing’s Sarcoma. Patient underwent chemotherapy for high risk ALL at induction phase with combination of vincristin, daunorubicin, L-asparginase, metotrexate high dose, prednison, and 6-mercaptopurine. After completing induction phase, the patient’s condition get worsening and later died.
CONCLUSION: ES survivors are at significant risk for secondary malignancies. Leukimia is one of which the most common secondary malignancies. Young children are particularly susceptible to the mutagenic effects of both chemotherapy and radiotherapy, as proven by several studies.
Peran Epigallocatechin-3-gallate (EGCG) dalam Menghambat Perkembangan Fibrosis Pleura, Ekspresi SCUBE3, dan Transforming Growth Factror-β (TGF-β) pada Pasien Empiema: sebuah tinjauan pustaka

Empyema in the lungs can cause pulmonary fibrosis which can cause restrictions in the movement of the lung parenchyma. Epigallocatechin-3-gallate (EGCG) is the most active polyphenolic compound in gambier leaves (Uncaria gambir Roxb), which is known to inhibit the occurrence of pulmonary fibrosis due to empyema. This literature review discusses the role of EGCG in inhibiting the development of pleural fibrosis in empyema patients.
EGCG prevents bleomycin-induced increase in ROS formation, reverses the decrease in antioxidant status, and increases Nrf2 activity. EGCG also reduces inflammatory markers such as NF-κB, TNFα, IL-1β, and MPO activity levels and reduces histological signs of inflammation and lung injury. EGCG lowers hydroxyproline and glycoconjugates, products of collagen metabolism, reduces matrix-degrading lysosomal hydrolases and improves ultrastructural changes in the lungs. EGCG also exerts antifibrotic activity by suppressing the expression of TGF-β and the SCUBE3 gene.
The EGCG compound inhibits the development of pulmonary fibrosis in empyema through antioxidant and antifibrotic activities by suppressing SUBE3 and TGF-β gene expression.
 
Empiema pada paru dapat menyebabkan terjadinya fibrosis paru yang dapat menyebabkan restriksi pada pergerakan parenkim paru. Epigallocatechin-3-gallate (EGCG) adalah senyawa polifenol paling aktif dalam daun gambir (Uncaria gambir Roxb) yang diketahui dapat menghambat terjadinya fibrosis paru akibat empiema. Tinjauan pustaka ini membahas mengenai peran EGCG dalam menghambat perkembangan fibrosis pleura pada pasien empiema.
EGCG mencegah peningkatan pembentukan ROS yang diinduksi bleomisin, mengembalikan penurunan status antioksidan, dan meningkatkan aktivitas Nrf2. EGCG juga mengurangi penanda peradangan seperti tingkat aktivitas NF-κB, TNFα, IL-1β dan MPO serta mengurangi tanda-tanda histologis peradangan dan cedera paru-paru. EGCG menurunkan kadar hidroksiprolin dan glikokonjugat, produk metabolisme kolagen, mengurangi hidrolase lisosom yang menurunkan matriks, dan memperbaiki perubahan ultrastruktur di paru-paru. EGCG juga melakukan aktivitas antifibrotik dengan menekan ekspresi TGF-β dan gen SCUBE3.
Senyawa EGCG mampu menghambat perkembangan fibrosis paru pada empiema melalui aktivitas antioksidan dan antifibrotik dengan menekan ekspresi gen SUBE3 dan TGF-β.
