Purpose. To investigate the influence of the axial length of the eyes with hypermetropia on the average ganglion cell-inner plexiform layer (GCIPL) thickness and to develop methods for correcting this effect. Material and methods. The study involved 183 patients (183 eyes) over the age of 40 years, 48 patients (48 eyes) with hypermetropia (axial length <22 mm) and 139 healthy subjects (139 eyes) of the same sex and age with axial length 22.5–24.5 mm (control group). Part of the control group (80 people) was examined earlier. Optical coherence tomography was performed on a Cirrus HD-OCT device (Carl Zeiss Meditec). Results. The average GCIPL thickness in the main group was 83.42±6.50 (from 71 to 99) µм and was higher than in the control group, where it was 80.39±5.91 (from 68 to 98) µm (p=0.004). In the control group normative data for the average GCIPL thickness were determined. For eyes with the axial length 20–22 mm corrections for calculating the equivalent average GCIPL thickness in emmetropic eyes have been developed, allowing comparison with the normative data. Conclusion. An original technique for assessing the average GCIPL thickness in patients with hypermetropia with axial length 20–22 mm, adapted to the Cirrus HD-OCT device, was developed. For this device, the normative database of healthy persons with emmetropia at the age of 41–80 years has been supplemented.

Purpose. To study the relationship between choroidal and retinal hemodynamics of the eyes in retinal vein occlusion (RVO) in young women to determine the features of their clinical course. Material and methods. The main group included 15 women (15 eyes), whose age ranged from 35 to 45 years, averaging 39.7±4.0 years. 20 somatically healthy women of comparable age were included in the control group. In addition to standard examination methods, all women underwent a comprehensive study of chorioretinal hemodynamics. The linear velocity of blood flow (LVBF) in the posterior short ciliary arteries (PSCA) was evaluated using a multifunctional ultrasound diagnostic device Logiq e (General Electric, USA). Macular blood flow features were studied using an optical coherence tomograph in angiography mode RTVue-100 (Optovue, Inc., USA). A comparative analysis of the studied indicators between the groups was carried out. Results. The results of the study revealed the presence of an interrelated statistically significant decrease in choroidal and retinal hemodynamics in young women with RVO relative to the group of healthy women (p<0.001). Conclusion. Taking into account the revealed direct relationship between choroidal and retinal hemodynamics in women with acute respiratory infections, we consider it appropriate and necessary to perform a simultaneous comprehensive study of various components of the hemodynamics of the posterior segment of the eye in the presence of this pathology: LVBF in the PSCA by color Doppler mapping and macular blood flow by OCT in angiography mode. These data can significantly expand the diagnostic capabilities of identifying the severity of the clinical course of acute respiratory infections and help predict the possible formation of neovascularization.

Purpose. To analyze an algorithm for infectious screening of cadaver corneal donors during corneal processing at the Eye Tissue Bank (ETB) of The Fyodorov Eye Microsurgery Federal State Institution and compare it with the European Eye Bank Association (EEBA) data from 2011 through 2015. Material and methods. Data analysis were done using the ETB in-house donor data registry and EEBA annual directory forms. The extracted data included the number of received eye globes, rates of inconclusive and serological tests for human immunodeficiency virus (type 1 and 2), Hepatitis B and C viruses, and Syphilis. Results. During the analyzed period 3479 eye globes were delivered in the ETB for the processing. Hemolysis caused exclusion for 13.9% (n=486) of corneas in the ETB. In opposite, the EEBA data demonstrated far lower rates of inconclusive tests. The positive serology tests lead to canceling 19.4% (n=676) of the incoming corneas in the ETB. Overall, the rates of positive tests were far higher in comparison with EEBA data. At the ETB, positive serological tests for HIV (type 1 and 2) and Syphilis had low variability annually, while the rates of Hepatitis B increased in 2015. Predomination of Hepatitis C was also noted. Often enough, the blood samples were multiply-infected. Conclusion. Overall, the positive serology and hemolysis were the major contraindications and led to exclusion 33.4% (n=1162) of incoming corneas in the ETB. Serological tests rates for indicated infections were higher in the ETB with predomination of Hepatitis C. An algorithm for infectious screening at the Eye Tissue Bank (ETB) of The S.

Introduction. The review presents the current data on the methods of surgical treatment of the initial stages of keratoconus in children, the possible manifestation of keratoconus as one of the symptoms of undifferentiated connective tissue dysplasia, as well as possible methods of prevention of the disease progression. Purpose. To present current literature data regarding surgical treatment of the initial stages of progressive keratoconus in children. Material and methods. For the review the literature sources were searched through the abstract databases PubMed and Scopus for the period up to and including 2022 using the following key words: ICRS, corneal collagen crosslinking, Keratoconus, connective tissue dysplasia. A total of 51 articles relevant to the review topic were selected. Results. Numerous studies have confirmed the effectiveness of timely surgery for the initial stages of keratoconus in improving the anatomical and functional outcomes of treatment of various diseases. However, even timely and perfectly performed surgery for progressive keratoconus may have different consequences depending on the degree of connective tissue dysplasia. Conclusion. The performed analysis of the literature allows to claim that keratoconus in children should be considered as a pathology related to the disturbance of structures and organization of collagen matrix of the whole body. It is also necessary to note that treatment tactics should be determined individually and be based on the age and values of comprehensive special examination of each particular child.

The article examines the issues of improving the accounting and control of payments to employees. It is determined that the problems of organization of the system of accounting and control of payments to employees are currently the most important for the economic activity of each business entity. This is relevant in connection with the transition of domestic accounting regulations to IFRS. It is proved that further unification of accounting according to national and international standards is inevitable and necessary. It has been argued that over the past few years, due to the unprecedented uncertainty caused by COVID-19, businesses have faced new challenges that have exposed business process weaknesses, declining demand and declining productivity. In such times, it is important to increase productivity and prepare the team to operate in the world of VUCO. The biggest driver of growth and at the same time a challenge is the digital transformation of business. Digitized online accounting tools will make the business industry more automated, accurate in detail and numbers, accessible to data, will be able to create more reliable data through automation, more secure storage through cloud storage. It is substantiated that a properly organized system of internal control is a kind of guarantor of achieving strategic and tactical goals of the organization. It is advisable to develop a Standard for internal control over the status of payments to employees in terms of deductions from wages, which will: establish effective control by specialists; to carry out examination of internal local acts of the enterprise for compliance with current legislation; take appropriate measures to prevent errors in calculations.

Published: June 2022

The article examines the impact of operational leverage on the process of forming the pricing policy of the enterprise. Approaches to the interpretation of the concept of "operational leverage" of domestic and foreign scientists are analyzed, their comparative characteristics are given. The key aspects of operational leverage are highlighted, including: impact; control mechanism; the relationship between profit and output; the relationship between cost structure and operating profit; share of fixed costs; assessment of pricing policy; pricing. It is determined that foreign scientists consider operational leverage in accordance with its impact on pricing and pricing policy. While domestic scientists examine from the standpoint of its impact on key indicators of financial and economic activities, including sales, sales revenue and operating profit. It is determined that due to the use of operational leverage the company is able to monitor the cost structure and make management decisions about the optimal price level of its products. A study of the main stages of pricing policy development identify six ones: the choice of target policy, demand assessment, cost analysis, analysis of competitors' prices, choice of pricing method, pricing, evaluation of the effectiveness of pricing policy. It is determined that the calculation of operating leverage should be carried out at the stage of cost analysis in order to determine their optimal structure in accordance with the resources, capabilities and potential of the enterprise. It was found that the level of operating leverage, which characterizes the ratio of fixed and variable costs in their structure, can reflect the optimal price and ability of the company to cover them and, if necessary, influence management decisions on sales and cost structure.

Published: June 2022

This scientific article is devoted to the shortcomings of the legal regulation of the status and organization of the work of public authorities and local governments in the context of military and postwar reconstruction of infrastructure. The urgency of this problem is that the current legal framework of Ukraine, which regulates the military and postwar reconstruction of the state, contains a large number of inaccuracies and needs to be comprehensively updated. The few Ukrainian scientific works that were designed to at least partially address the issue of infrastructure reconstruction within the state do not cover most of the aspects that arise in the process of this reconstruction. The proposed article aims to offer their own ideas for improving the regulatory framework of Ukraine, which should regulate the process of restoring damaged and destroyed state infrastructure. To this end, the article examines the legal framework governing the status and organization of public authorities and local governments. Further in the scientific work it is noted that the renewal of the current legal framework for the reconstruction of infrastructure should take place exclusively in accordance with the plans for the integration of the national legal framework into the European legal space. Taking into account all these factors, the authors of the article summarized that the only comprehensive way to regulate the process of reconstruction of Ukraine is to create a Plan for reconstruction of damaged infrastructure during martial law and in the reconstruction period and its subsequent legal consolidation. This plan should include changes at the state level (Ministry of Infrastructure of Ukraine, Cabinet of Ministers of Ukraine, committees in the Verkhovna Rada of Ukraine), changes at the local level (military and military-civil administrations, local and regional councils, status of (united) territorial communities) , as well as certain additional changes (creation of certain commissions and subdivisions). A separate list of the most important provisions that must be set out in the reconstruction plan was presented separately.

Published: June 2022

The article is devoted to the issue of theoretical and legal review of steps to establish the Bureau of Economic Security of Ukraine as a subject for the protection of the national economy. It is emphasized that, given the novelty and, consequently, the lack of research on a wide range of issues regarding the existing legal status of the institution, the focus should be on the historical aspect. It is seen that the application of this approach will contribute to the completeness and comprehensiveness of the study and the meaningful disclosure of many problematic vectors of the functioning of the analyzed subject. In order to facilitate the logic of the research material, a conditional starting point was identified, which became a real "impetus" for the implementation of measures to establish a new body to protect the national economy (ratification of the Association Agreement between Ukraine and the European Union). Energy and their Member States, on the other hand, dated June 27, 2014 (hereinafter referred to as the Association Agreement between Ukraine and the EU). It is proposed to represent this gradation as follows: 1) the period from the moment of ratification of the Association Agreement of Ukraine with the EU dated June 27, 2014 until the beginning of implementation of measures to establish and launch the Bureau of Economic Security of Ukraine (September 16, 2014 – July 2, 2020); 2) the period from the beginning of the implementation of measures for the creation and launch of the research subject to the present (02.07.2020 – present). The first stage focused on draft legislative acts, which, according to the authors, were to form the legal basis for the activities of the institution, as well as a comparative description of the latter. Within the framework of the second stage research, the documents (drafts and normative legal acts) that form the basis of the work of the Bureau of Economic Security of Ukraine were considered and analyzed.

Information support of structural units of law enforcement agencies in current rapid development, changes in current legislation of Ukraine and modern globalization processes is one of the main factors and aspects of the proper functioning of the system as a holistic phenomenon. The existence of an extensive structure of information distribution and rules of use and disposal makes it necessary for proper doctrinal, legislative and practical settlement of this issue, as it affects not only the quality of local government, but also matters of national importance. Thus, the European Court of Human Rights has repeatedly noted the concept of privacy encompasses the physical and psychological integrity of the individual. Therefore, it may include various aspects of the physical and social self-identification of a person, which is a good reason to believe that real access to confidential information about individuals law enforcement agencies have an objective obligation and a single procedure for maintaining confidential information - no, that is urgent issues and problems in the development of modern society.
MODERN TRENDS OF COLLABORATION OF UKRAINE AND EU AT THE CONTEXT OF ENSURING OF FOREIGN ECONOMIC SECURITY
Authors:   Educational and Scientific Institute of Public Administration and Civil Service of Taras Shevchenko National University of Kyiv, Ivanova Viktoriia
Published: June 2022

The article examines modern trends of development of Ukraine's foreign economic activity as an important component of foreign economic security. The Law of Ukraine "On National Security" defines the fundamental national interests of Ukraine, through which the idea of foreign economic security of the state, because sovereignty and territorial integrity, economic development, close cooperation with European countries and organizations are possible through the development and implementation of effective public mechanisms in the fild of foreign economic security. It is noted that foreign economic activity is the basis for export-import operations, purchase and sale of goods and services, filling the budget, realization of national interests, ensuring economic security and more. It is established that Ukraine is an active participant in international economic activity. As of the beginning of 2022, Ukraine carried out trade operations with more than 170 countries. In 2021, compared to 2020, imports of goods increased by 34% to $72.84 billion, and exports - by 38.4%, to $68.07 billion. At the same time, in 2021 the export of Ukrainian goods and services to the EU reached $26.8 billion. The volume of imports of 27 EU countries to Ukraine amounted to $28.9 billion. The EU is Ukraine's main trading partner at the present stage. The article points out that as a result of hostilities there have been significant changes in Ukraine's foreign economic activity. Analysis of this impact on foreign economic security can be divided into the following groups of problems: the inability to carry out production; difficulties in ensuring the sale of goods; financial problems; difficulties in communications, investment and social projects. It is noted that in support of Ukraine, the European Union is lifting trade restrictions on Ukrainian exports. The abolition of customs duties applies to exports of industrial products, fruits and vegetables from Ukraine, as well as anti- dumping duties on steel imports. Thus, the European Union is trying to support Ukraine's economic system, create conditions for at least minimal development and economic activity.
Cellular Exposure to Chloroacetanilide Herbicides Induces Distinct Protein Destabilization Profiles
Authors: Quanrud Guy , Balamurugan Sunil , Canizal Carolina , Genereux Joseph
Published: June 2022

Herbicides in the popular chloroacetanilide class harbor a potent electrophilic moiety, which can damage proteins through nucleophilic substitution. In general, damaged proteins are subject to misfolding. Accumulation of misfolded proteins compromises cellular integrity by disrupting cellular proteostasis networks, which can further destabilize the cellular proteome. While direct conjugation targets can be discovered through affinity-based protein profiling, there are few approaches to probe how cellular exposure to toxicants impacts the stability of the proteome. We apply a quantitative proteomics methodology to identify chloroacetanilide-destabilized proteins in HEK293T cells based on their binding to the H31Q mutant of the human Hsp40 chaperone DNAJB8. We find that brief cellular exposure to the chloroacetanilides acetochlor, alachlor, and propachlor induces misfolding of dozens of cellular proteins. These herbicides feature distinct but overlapping profiles of protein destabilization, highly concentrated in proteins with reactive cysteine residues. Propachlor induces a general increase in protein aggregation, and selectively targets GAPDH and PARK7, leading to a decrease in their cellular activities. GAPDH is primarily modified by direct conjugation of propachlor at a catalytic cysteine residue, leading to global destabilization of the protein. The Hsp40 affinity strategy is an effective technique to profile cellular proteins that are destabilized by cellular toxin exposure. Raw proteomics data is available through the PRIDE Archive at PXD030635.

Published: June 2022

Efficient CO2 capture is indispensable for achieving a carbon-neutral society while maintaining a high quality of life. Since the discovery that ionic liquids (ILs) can absorb CO2, various solvents composed of molecular ions have been developed and their CO2 solubility has been studied. However, it is challenging to optimize these materials to realize targeted properties as the number of candidate ion combinations for designing novel ILs is of the order of 1018. In this study, electronic- structure informatics was applied as an interdisciplinary approach to quantum chemistry calculations, and combined with machine learning to search 402,114 IL candidates to identify those with better CO2 solubility than known materials. Guided by the machine-learning results, trihexyl(tetradecyl)phosphonium perfluorooctanesulfonate was synthesized and it was experimentally confirmed that this IL has higher CO2 solubility than trihexyl(tetradecyl)phosphonium bis(trifluoromethanesulfonyl)amide, which is the previous best IL for CO2 absorption. The method developed in this study could be transferable to gas-absorbing liquids in general, such as deep eutectic solvents (hydrogen-bonded mixed organic solvents in a broad sense), which also have numerous practical applications. Therefore, we believe that our method for developing functional liquids will significantly contribute to the development of a carbon-neutral society.

Published: June 2022

Social media as a forum for communication and information, has a major contribution in its role in distributing and or transmitting information related to news related to social phenomena, one of which is government policies. Due to its nature as a communication medium, it creates space for the public to comment and express their aspirations on issues related to certain policies. This writing aims to describe the phenomenon of social criticism on social media platforms in the perspective of hyperpersonal communication. The advantage of hyperpersonal communication is how to deliver messages without being bound by space and time, causing an opportunity to plan the message to be conveyed. With this advantage, users can be wiser in using social media, choosing the right channel, and time to compose and distribute message content before deciding to respond to social issues or problems resulting from government policies.Keywords : Social Criticism, Policy, Social Media, Hyperpersonal Communication
Feminismos, memoria y resistencia en América Latina. Tomo 2. Narrar para no olvidar: memoria y movimientos de mujeres y feministas
Authors: Romero García Velvet , Calderón Cisneros Araceli
Published: June 2022

El presente tomo tiene el objetivo de poner en diálogo diversos enfoques sobre la relación entre las memorias y las resistencias protagonizadas por movimientos de mujeres y feministas de Abya Yala a través de experiencias de mujeres de Argentina, Chile, Brasil, México, Nicaragua, Perú, Colombia, El Salvador y Honduras. El libro permite pensar en una suerte de memoria continental generizada a través de cuatro hilos conductores. Uno de estos hilos es la lucha de las madres de personas desaparecidas, pues existe en América Latina una genealogía del activismo de madres cuyos hijos e hijas han sido desaparecidos o asesinados, que incluye a grupos como: las Madres de Plaza de Mayo, en Argentina; las madres y padres de los normalistas de Ayotzinapa, en México, y los familiares de víctimas de brutalidad policial racializada en Estados Unidos. También hacen parte de esta genealogía los casos documentados en los tres primeros capítulos de este libro: las madres de personas mapuches víctimas de desaparición durante la dictadura en Chile; las madres que lideran diversos colectivos emergentes de buscadores en Guanajuato, México, y la Asociación de Madres de Abril, en Nicaragua.

O uso de drenos verticais em depósitos de solos moles promove a aceleração dos recalques por meio da drenagem da água, reduzindo o volume de vazios, aumentando a resistência ao cisalhamento do solo e melhorando a capacidade de suporte. São elementos constituídos por materiais sintéticos que são cravados verticalmente no terreno, dispostos em malha. Este artigo avalia a aplicabilidade de drenos verticais como solução para acelerar os recalques de um aterro construído sobre solos moles, localizado em Recife, Pernambuco. Foram definidas as necessidades do projeto (profundidade dos drenos, tempo e grau de adensamento) e determinada as grandezas geométricas dos geodrenos (diâmetro equivalente, diâmetro de influência, diâmetro da área amolgada), espaçamento entre os geodrenos e quantidade total de geodrenos necessários para um determinado tempo de adensamento. Optou-se pela avaliação para dois tipos de drenos distintos o CX1000 da TDM Brasil e 1S 20.2 da Maccaferri do Brasil, que se diferenciam geometricamente pela espessura da seção transversal. Obteve-se para ambos os casos o comprimento total necessário para cada um dos drenos e os custos estimados. Os resultados obtidos mostraram redução de até 89 anos, se comparado com a situação sem o uso dos drenos, o que possibilitou que as deformações desejadas ocorressem em até 5 anos, tornando evidente a eficiência no uso deste material.

Vertical drains as solution to accelerate the settlement of embankment on soft soil
Abstract
The use of vertical drains in soft soil deposits promotes the acceleration of settlements through the drainage of water, reducing the void volume increasing the shear strenght of the soil and improving the support capacity. They are elements made of synthetic materials that are driven vertically into the ground, arranged in mesh. This article evaluates the applicability of vertical drains as a solution to accelerate the settlement of an embankment on soft soil deposit located in Recife, Pernambuco. The parameters of the project were defined (depth of drains, time and degree of consolidation) and the geometrical quantities of the geodrains were determined (equivalent diameter, diameter of influence, diameter of the dented area), spacing between the geodrains and the total amount of geodrain drains needed to a certain consolidation time. We opted for the evaluation for two different types of drains, the CX1000 from TDM Brasil and 1S 20.2 from Maccaferri do Brasil, which differ geometrically by the thickness of the cross section. For both cases, the total length required for each of the drains was obtained and the estimated cost. The results obtained showed a reduction of up to 89 years, when compared to the situation without the use of drains, which allowed the desired deformations to occur in up to 5 years, making evident the efficiency in the use of this material.

One of the most important discoveries in the field of deep learning in recent years is the Generative Adversarial Networks (GAN). It offers great convenience and flexibility for image-to-image conversion processes. This study aims to obtain thermal images from visible band colour images by using Pix2Pix Network, which is a Conditionally Generative Adversarial Network (cGAN). For this purpose, a data set has been prepared by taking facial images at different angles in the visible and infrared bands. By applying image processing methods on this created dataset, pixel-by-pixel matching process was performed. Synthetic thermal face images were obtained thanks to this learning network fed with facial images consisting of visible and long wavelength infrared image (LWIR) pairs. In the generator and discriminator deep networks of the Pix2Pix GAN, Batch Normalization and Instance Normalization methods are applied and their effects on the outputs are examined. The same process has also been tested on the Google Maps dataset and thus its effects on different datasets has been demonstrated. Similarity values between synthetic outputs and real images of both studies has been calculated with several image quality metrics. The performance of this generated model in creating the details in the infrared band is also given in the conclusion section.

Shopping carts are essential parts used in shopping. There are differences between shopping carts used today. The most prominent of these differences is that some carts have only the front two free rolling wheels, the rear two wheels are fixed rolling wheels, and some carts have four free rolling wheels. In this study, the effects of this difference in shopping carts on joints of the human body under different conditions were simulated using analysis software and the results were compared. As a result, it has been determined that European style shopping carts with four free rolling wheels need more force when going straight than other type of shopping carts with two free rolling wheels and need less force in case of rotation. In addition, when these forces are applied on the human model and gravity is neglected, it has been determined that the reaction of the joints is close to each other.

Pektinazlar, pektik polimerdeki glikozidik bağların hidrolizini katalizleyen enzim ailesinin genel bir adıdır. Bu çalışmada Bacillus pumilus bakterisinin kesikli bir biyoreaktörde pektinaz grubu enzimlerden endo-pektinaz, ekzo-pektinaz ve pektin liyaz üretimi üzerine karıştırma ve hava akış hızlarının etkileri araştırılmıştır. Ayrıca oksijen tüketim hızı ve sıvı faz hacimsel kütle transfer katsayısının değişimi ve karıştırma için güç sayısının hesabı da yapılmıştır. Bacillus pumilus bakterisinin pektinaz grubu enzimlerin üretimi için optimum karıştırma hızı değerinin 300 rpm olduğu tayin edilmiştir. Hava akış hızının enzim aktivite değerlerine etkisinin incelendiği deneylerde en yüksek enzim aktivite değerleri 0.1 vvm’ de elde edilmiştir. 300 rpm karıştırma hızında ve 0.1 vvm hava akış hızında en yüksek pektin liyaz aktivitesi 66. saatte 19.5, ekzo-pektinaz aktivitesi 28. saatte 10.69, endo-pektinaz aktivitesi 66. saatte 102.13 U mL-1 olarak kaydedilmiştir. Sıvı faz hacimsel oksijen transfer katsayısı değeri karıştırma hızının artmasıyla artmıştır. 300 rpm karıştırma hızında en yüksek kLa değeri 26. saatte 0.1524 s-1, 400 rpm’ de 60. saatte 0.2623 s-1 olarak kaydedilmiştir. Üstel üreme bölgesinde oksijen tüketim hızı zamanla artmış, üstel üreme bölgesinden sonra ise azalmıştır. Karıştırma hızı arttırıldığında ise oksijen tüketim hızında azalma meydana gelmiştir. Optimum 300 rpm’ de, sisteme havalandırmanın yapıldığı durumda ki güç değeri Pg= 1.95 W olarak bulunmuştur.

Cumhuriyet Dönemindeki spor faaliyetlerinin temelleri Osmanlı Devleti’nin son dönemine kadar uzanmaktadır. Türkiye Cumhuriyeti Devleti’nde de spora önem verilmiş ve sağlam kafa sağlam vücutta bulunur şiarıyla spor politikaları etkinlik
kazanmıştır. Atatürk, bir sporcuda yalnızca fiziksel güç ve yetenek aramamış, bu özellikler ile birlikte iyi ahlak ve zekânın da bulunmasını istemiştir. Öyle ki: “Ben sporcunun zeki, çevik ve aynı zamanda ahlaklı olanını severim”
sözüyle ile spora ve sporcuya verdiği önemi dile getirmiştir. 1932 yılında kurulan Halkevleri, milli kültürün gelişimi, inkılapların etkisinin hissedilmesi ve topluma yerleşmesini amaç edinen çeşitli şubelerde hizmet verirken;
Türk sporuna hizmeti de büyük ve önemli bir görev edinmiştir. Maraş’ta bilinen ilk spor kulübü ise 1920 yılında kurulan İdman Yurdu olmuştur. 1925 yılında şehir merkezinde; Kalespor, Ahırdağspor ve Feneryoluspor kurulmuştur. Ancak
şehirde spor faaliyetleri için alan yetersiz kalmıştır. Daha sonra halkevinin kuruluşuyla, sportif faaliyetler ve takımlar genel olarak halkevinin spor şubesine bağlanmıştır. Gaziantep’te spora yönelik faaliyetler oldukça eskiye
dayanmaktadır. Cumhuriyet Dönemi’nde ise Gaziantep’te ilk spor örgütü 1927 yılında kurulmuştur. Mahalli kuruluşlar olarak faaliyet gösteren bu dönemdeki çeşitli spor kulüpleri, kendi aralarında sportif aktiviteler düzenlerken ayrıca
çevre il ve ilçelerin spor kulüpleri ile özel maçlar da düzenlemişlerdir. 24 Haziran 1932 tarihinde Gaziantep Halkevinin açılması ile şehrin spor kulüplerinin yönetimi Halkevi Spor Şubesi bünyesine verilmiştir. Bu çalışmada Erken
Cumhuriyet Döneminde (1923-1950) Gaziantep ve Maraş’ta spor hayatı ele alınırken Halkevi Spor Şubesi tarafından gerçekleştirilen spor faaliyetlerine de yer verilmiştir
Glacial Morphology of Mount Süphan

Süphan Dağı, kuzeydoğu-güneybatı yönünde dizilerek Ağrı'dan Nemrut'a kadar uzanan Doğu Anadolu'nun genç volkanları arasında yer alır ve 4058 metreye ulaşan yüksekliği ile Türkiye'nin tüm dorukları içinde üçüncü, volkan konileri içinde
ise Ağrı’dan sonra ikinci sırada gelir. Van Gölü’nün hemen kuzeyinde yer alan Süphan Dağı’nın güneybatısında Bitlis’in Adilcevaz, doğusunda Van’ın Erciş, kuzeyinde Ağrı’nın Patnos ve kuzeybatısında da Muş’un Malazgirt ilçesi bulunur.
Dağın batı, güney ve doğu yamaçları Adilcevaz, kuzey yamaçları Patnos ve kuzeybatı kısımları da Malazgirt ilçesi içerisinde kalır. Bu araştırmada, Harita Genel Komutanlığı’nın 1/35.000 ölçekli stereoskopik hava fotoğrafları ve
beş yıl süren arazi gözlemlerinden yararlanılarak, Süphan Dağı’nın ayrıntılı jeomorfoloji haritası hazırlanmıştır. Böylece başta turizm planlaması olmak üzere, kır yerleşmeleri ve yaylacılık gibi konuları kapsayan dağ yönetiminin
temelleri oluşturulmuştur. Sonuç olarak günümüzden yaklaşık 18-20 bin yıl önce gerçekleşmiş olan son glasiyalin son evresi esnasında Süphan, kuzeyde 3100, güneyde ise 3300 metrelerden itibaren kalıcı karlarla kaplanmış ve yakın
yıllara (1940-1950’liler) kadar Ağrı’da olduğu gibi bir külah buzulla örtülmüştür. Bu buzullardan çıkan diller kuzeyde 2650-2700 metrelere, güneyde ise 2950-3000 metrelere kadar sarkmışlardır. Bakı koşulları yanında yağış getiren
sistemlerin hep batıdan geliyor olmaları nedeniyle buzul kalınlıklarının en fazla olduğu kısımları, kuzey yamacın batı bölümleri ile kuzeybatı yamaçlar oluştururken, doğu yamaç, yağış gölgesinde kaldığı için buzul kalınlıklarının
en az olduğu yamaç olmuştur. Fakat genel olarak Türkiye’nin az yağışlı ve karasal iç bölgelerinde yer alan Süphan gibi yüksek volkanik dağlar üzerindeki buzullar, yeterli kar yağışıyla beslenemedikleri için ne yeteri kadar kalınlaşabilmişler,
ne de fazlaca hareketli olabilmişlerdir. Bu nedenle hem Kuaterner kalıcı kar sınırı alçalması kenar dağlara göre, 500 metre gibi düşük bir düzeyde kalmış, hem de buzul dilleri, içinden çıktıkları sirklerden aşağılara doğru en fazla
1,5-2 kilometre kadar sarkabilmişlerdir.
