ÜRÜN TASARIMINDA KÜLTÜREL SÜRDÜRÜLEBİLİRLİK VE ÖZGÜN DEĞER
Authors: NAS Emine
Published: December 2022

Bireylerin yaşam döngüleri içinde kendiliğinden kazanılan alışkanlıklar olarak tanımlanan kültür, toplumun sosyal mirası olarak görülmektedir. Kültürel özellikler, geçmiş, güncel ve gelecek arasındaki ilişki ekseninde değişkenlik göstermekte ve buna bağlı olarak evirilmektedir. Toplumların sahip oldukları kültürel değerlerin yüksek etkileşimde olduğu en önemli alanlar içerisinde sanatsal yapı ve tasarım olgusu yer almaktadır. Ürün tasarım sürecinde kültürel bir özelliğin tasarıma entegrasyonu bir veya birden fazla bulgunun değerlendirilmesine bağlıdır. Seçilen kavramlar bir taraftan biçimsel bir özelliğe nitelik kazandırırken, diğer taraftan da biçime anlam yükleme vasfı üstlenir. Dolayısı ile tasarım sürecinde ürün kültürel bir anlatım ifadesine evirilmeye başlar. Bu değişim özgün tasarım gruplarının oluşması ve kümelenmesini sağlar. Kimi zaman bu süreç olumlu etkiler ile kültürün dinamik özelliklerini bir avantaj olarak yansıttığı gibi kimi zaman da ters orantıda bir görünüm sergiler. Bu süreçte tasarım yöntemi çok iyi planlanmalıdır. Ezberlenmiş kültürel kodların yeni oluşumlarının doğru okunup okunmayacağı da sürecin doğru yönetiminde belirleyici bir rol oynar. Burada devreye giren dürtü fark yaratma ve özgünlük tutkusudur. Çalışma nitel yöntem ile kurgulanmış olup, örneklem olasılığa dayalı olmayan biçimde araştırmacının kendi bilgi ve tecrübesine dayanarak belirlediği popülasyondan kasti olarak belirlenmiştir. Örneklem seçiminde kültürel özelliği bulunan unsurların güncel tasarımlardaki kullanım biçimlerinde görülen yeni durumlar ve sorunlar öncelikli kriterdir. Çalışmada; kültürel değerleri özgün görselleştirme, yorumlama, yenileme çerçevesinde gelişim gösteren bakış açılarını belirlemek ve sürdürülebilirlik anlayışı çerçevesinde özgün değeri olan tasarım ürünlerine karşı bilinç oluşturmak temel amaçlardır. Tasarım dünyasında özgün değer kavramı ayırt edici özelliğinin yanı sıra soyut derecelendirilmesi ile de tartışmaya açıktır. Seçici bir etkendir ve tercih edilme noktasında görünür özellikler taşır. Kolay ulaşılabilir olan kültürel ögeler etkili ve doğru kullanıldıkları taktirde orijinal fikirlerin temel kaynağı haline gelirler. “Kendi tarzını bulma”-“özgün değer yaratma” çabalarında bir ipucu niteliğinde olan kültür özellikler tasarım stillerinde zengin bir profilin oluşmasını yol açmıştır. Ancak özgünlük miti bu profil içerisinde her tasarım grubuna olumlu ivme ve avantaj sağlamamıştır. Gelenek ve yaratıcılık arasında sentezler kurulmaya başlanmış ve bu durum özgür ve özgün tasarımların şekillenmesini sağladığı gibi, sanatsal gelişim kaynaklarını ve onları oluşturan nedenlerin iyi araştırılıp sorgulaması gereğini de ortaya çıkartmıştır.

Bilgi ve iletişim teknolojilerinde (BİT) meydana gelen gelişmelerin günlük yaşantıya büyük etkisi olmuştur. Akıllı teknolojiler sadece insan yaşantısına değil kurumsal işleyişe de uyarlanmıştır. Dijitalizm ve kurum buluşması e-devlet platformları ile başlatılırken süreç içinde yeni platformlar devreye sokulmuştur. Özellikle Covid-19 salgını bireylerin bilgi erişimi konusundaki beklenti ve çabalarını arttırmıştır. Salgın sırasında eğitim, sağlık, iş yaşamı başta olmak üzere dijital platform ve akıllı teknoloji kullanımı büyük artış göstermiştir. Salgın süreci akıllı teknoloji kullanımı konusunda bireylerin-kurumların potansiyellerini ve becerileri ortaya çıkarmıştır. Pek çok kurum ve kişinin kısıtlamalar sırasında akıllı teknolojilere artan ilgisi halen sürmektedir. Salgın öncesinde başlayan ama salgınla öne çıkan konulardan biri ise çevre sorunlarının tespiti, izlenmesi, analizi ve çözüm üretilmesi olmuştur. Hava, su ve toprak üzerindeki insan kaynaklı tahribatın yol açtığı kirlilik acil tedbir alınması gereken kent sorunlarındandır. İklim değişikliği konusunda Birleşmiş Milletler (BM) öncülüğünde sürdürülen girişimlerin başarıya ulaşmasında yerel yönetimlerin ve yerel halkın büyük sorumluluğu bulunmaktadır. Bu sorumluluk artan kent nüfusuyla doğrudan ilişkilidir. Nüfus projeksiyonları açısından 2035 yılında metropollerde yaşayan insan sayısının dünya nüfusunun % 39'unu temsil eden 3,47 milyar kişiye ulaşacağı ve 15 yıl içinde yaklaşık 1 milyar insanın büyük kentlerde ikamet edeceği tahmin edilmektedir. BM, 2050 yılına kadar dünya nüfusunun % 68'inin kentsel alanlarda yaşayacağını öngörmektedir. Covid-19 salgınıyla elde edilen akıllı teknoloji deneyimlerinin çevre kirliliğiyle mücadelede kullanımı önem kazanmıştır. 28 Ocak 2021 tarihinde İzmir Büyükşehir Belediyesi tarafından erişime açılan “Açık veri platformu” içeriğinde akıllı teknoloji ve çevre buluşmasını sağlamaktadır. Çalışmamızın amacı artan çevre sorunlarıyla mücadele açısından akıllı teknoloji uygulamalarının katkısını ele almaktır. Literatür incelemesine dayalı tarama yöntemiyle gerçekleştirilen çalışmamızda açık veri platformu üzerinden gerçekleştirilen “akıllı çevre girişimleri” incelenmektedir. Bireylerin ve kurumların akıllı teknoloji konusunda gelişen yatkınlıkları ve talepleri temel motivasyonumuzu oluşturmuştur.

Technologies for creating nanocoatings with unique properties on polymeric materials are being actively developed and used in human activities. The possibilities of using such composite materials will depend on the physical and mechanical properties of the coatings. To determine the mechanical characteristics of nanocoatings on polymeric materials, there are used nanoindentation methods. The results of nanoindentation of a hard coating are significantly affected by a soft polymer substrate. On the other hand, there are various experimental methods and analytical models for determining the mechanical properties of materials at the macroscopic level. The use of these approaches would make it possible to obtain the values of the mechanical properties of nanocoatings, which could be used to calculate and analyze the stress-strain state of products with nanocoatings. In this study, we demonstrate the application of a three-point bending test to determine the elastic modulus of a carbonized nanolayer formed by high-energy nitrogen ion treatment of a polyurethane surface. By selecting the optimal thickness of the test samples, it is possible to create conditions for determining the modulus of elasticity of a nanolayer on a polymer substrate using a three-point bending test. We have obtained statistically significant differences between the values of the elastic modulus of untreated and plasma-treated samples. Using a composite beam model, the modulus of elasticity of the carbonized nanolayer was determined.

Diversity, quantitative development and distribution of phytoplankton species were investigated. The study area included southeastern part of the Ross Sea (near Roosevelt Island) (station 3), transect 1 along the 156°W (Ross Sea at Cape Colbeck), near Russkaya station (transect 2) along the 138°W and the Bransfield Strait (transect 3) in February-March 2020, based on the data of 65th Russian Antarctic Expedition. 49 algae taxa from 7 divisions with a predominance of diatoms were identified in the phytoplankton. The spatial distribution of phytoplankton was characterized by heterogeneity which is associated with currents in the study areas, ice conditions, climatic and thermohaline factors. Development of diatoms is typical to the entire studied area. The dominant species (more than 10% of the algae population) were representatives of the genera Fragilariopsis, Chaetoceros, Actinocyclus, Corethron and Phaeocystis. The highest phytoplankton abundance (up to 264×103 cells/l) were obtained for transect 2 stations.

The data on the flora of the port of Yamburg (67° 54' s. w., 74° 48' v. d.) on the Taz Peninsula, 148.5 km north of the Arctic Circle, in the Yamalo-Nenets Autonomous Okrug of the Tyumen Region are presented. The port area is about 4 hectares. The whole area is covered with sand. There is no continuous vegetation cover, it is very sparse. 42 species of vascular plants were found (28.07.2013). During 3 years of forwarding work in the Arctic (2012-2014), Poa lanata Scribn. et Merrt, Lathyrus quinquenervis (Miq.) Litv. ex Kom. and Lathyrus pilosus Cham. ´ L. quinquenervis (Miq.) Litv. ex Kom. were collected only in the port of Yamburg. It is established that these species are the result of repeated migrations. They are rare, so they have not been noted elsewhere. It is revealed that all other species are introduced from adjacent natural territories and are at different stages of the apophitization process. In the course of the conducted studies, it was noted that representatives of the Poaceae family (17 species) predominate, Fabaceae (5 species) are in second place, followed by Asteraceae and Polygonaceae (4 species each). The most widespread species were Artemisia tilesii, Crepis multicaulis, Tripleurospermum hookeri. There are only 3 drift species: Poa angustifolia, Puccinellia distans, Puccinellia hauptiana. The small number of species is explained by the northern location, a thick layer of sand and the weak role of river transport as a source of drift.

Functional activity of Lactobacillus spp. was evatuated under the influence of bacterial diamines. The dose-dependent effect of putrescine on growth characteristics of clinical strains has been established. Cadaverine at a concentration of 1 mmol/l in the culture medium significantly stimulated the accumulation of biomass of the tested strains. The results obtained confirm the destabilizing effect of bacterial amines agents on vaginal Lactobacillus spp. and thus their important direct role in weakening the biological protection of the vaginal microenvironment.

The article discusses the selection of optimal conditions for the lyophilization of poly- and monoclonal peroxidase conjugates used in the direct version of the enzyme immunoassay intended for the cholera toxin detection in Vibrio cholerae O1, O139 strains. Effective stabilizers included in protective media comprise 1 % sucrose, 1 % sodium thiosulfate, 0.5 % egg albumin, or 0.5 % bovine serum albumin. Their use increases the shelf life, increases stability, and contributes to the preservation of high sensitivity and specificity of poly- and monoclonal peroxidase conjugates. Evaluation of the serological activity of antitoxic conjugates in ELISA after lyophilization in a protective medium with stabilizers showed that it remains at the initial level. The results of testing lyophilized conjugates during storage allow us to speak about the possibility of their use for two years without changing the main indicators.

Value chain stress resilience and behavioral strategies of companies in Russian coal industry
Authors: Goosen Е. V. , Nikitenko S. M. , Klishin V. I. , Kagan E. S. , Patrakov Y. F.
Published: December 2022

Under the current conditions, the Russian coal industry is under unprecedented external pressure: it is both the imposed sanctions and the need to meet strict environmental requirements that inevitably lead to the closure of part of the enterprises, the collapse of value chains (VCs) in the coal and related industries. As a result, a complex restructuring of the industry is required. To carry it out successfully, a reliable criterion is needed to assess the prospects for the long-term development of both individual companies and VCs as a whole. From the authors’ point of view, the degree of stress resilience of VCs is the criterion needed.The article deals with the evaluation of the long-term development prospects of the coal industry based on the established stress resilience of VCs and the related strategies of coal companies’ behavior. The authors proposed an algorithm for assessing the stress resilience of VCs in the coal industry: a description of the aspects and typology of VCs in the Russian coal industry; an assessment of their current stress resilience; a description of the survival strategy of the companies included in the VCs; an assessment of the prospects for sustaining VCs under sanctions. Subsequently, this article presents theresults of the stress resilience assessment of 169 coal companies operating in 110 different VCs between 2010 and 2021.The authors created a typology of VCs in the coal industry, which makes it possible to identify three basic types of VCs in the domestic coal industry: two integrated – the captive market and the hierarchical market – and one non-integrated market. Analysis of companies operating from 2010 to 2021 showed that 90 out of 169 businesses (53%) operated as integrated companies (hierarchical and captive VCs), the remaining 79 were classified as market ones.For each type we measured overall stress resilience (βrescom), indicating the VC degree of recovery from shocks; robustness (βres), the VC ability to withstand (swallow) shocks; adaptability (βrec), the VC flexibility CDS and the ability to recover quickly after a shock. The analysis conducted by the authors showed that the stress resilience of key segments of the coal industry is low and tends to decrease and will only decrease in the long run. The research also found that systemically important companies are in the most difficult situation. They belong to the hierarchical VCs, especially the energyand coal companies, which are mainly focused on foreign markets. Their cooperative survival strategy does not even maintain the current level of stress resilience. Market and relational VCs are in a more favorable position. As a result, the authors conclude that part of the coal companies will inevitably close and for the other part a profound restructuring will be necessary, while the current survival strategies of the companies will not allow to solve this problem by themselves and an active participation of the state will be necessary.
Selection of Temperature regimes for conditioning and flotation of diamond-bearing kimberlite with compound collectors
Authors: Morozov V. V. , Kovalenko E. G. , Dvoichenkova G. P. , Chut-Dy V. A.
Published: December 2022

The condition for stable fixation of a collector on the surface of diamonds and their flotation is the use of collectors of the optimal fractional composition and the choice of the optimum temperature regime of the process. To determine the parameters of the diamond flotation regime, the regularities of the phase transitions of asphaltene-tar fractions at increasing temperature and diluting F-5 with technical diesel fraction were established. It was demonstrated that increasing the collector temperature leads to the transfer of asphaltenetar fractions to a dissolved and finely dispersed state. To an even greater extent, dissolving asphaltene-tar fractions is facilitated by the addition of medium- and low-molecular weight fractions of oil, for instance, a technical diesel fraction.It was revealed that the KM-10, KM-14, and KM-18 reagents, being compounds of F-5 fuel oil with technical diesel fraction (10–18 % DF), were characterized by optimal viscosity and ability to displace aqueous phase from a diamond surface, thus ensuring stable hydrophobization and high floatability of diamonds. The optimal temperature regime has been selected, which involved maintaining the temperature at the stage of conditioning with the collector at +30–40 °С, at which the maximum selective fixation of compound collectors on the diamond surface, characterized by the value of the limiting wetting angle, was achieved. The flotation tests have confirmed that the best results are achieved at a temperature of +30–40 °С at the conditioning stage and +14–24 °С at the flotation stage. At +24 °С, the best results were obtained for the relatively less diluted KM-10 and KM-14 fuel oils obtained by diluting F-5 fuel oil with a technical diesel fraction at the diluent volume fractions of 10 and 14 %. The diamond recovery achieved in the flotation tests was 3.8–4.5 % higher than when using the traditional collector, F-5 fuel oil. At +14 °С, the highly diluted fuel oil, KM-18 with a volume fraction of 18 % of the technical diesel fraction, demonstrated better collecting abilities.The optimal compositions of the collector and the regimes of feed preparation and flotation were tested at a foam separation unit. The tests showed that it is possible to increase diamond recovery into concentrate by 2.3–4.5 %. The recommendations are provided on the use of thermal conditioning in the foam separation cycle and maintaining the conditioning medium temperature at +30–40 °С and the foam separation temperature at +14–24 °С.

Investigation of automorphism group for code associated with optimal curve of genus three
Authors:   Immanuel Kant Baltic Federal University, Malygina E. S.
Published: December 2022

The main result of this paper is contained in two theorems. In the first theorem, it is proved that the mapping λ : ℒ(mP∞) → ℒ(mP∞) has the multiplicative property on the corresponding Riemann - Roch space associated with the divisor mP∞ which defines some algebraic-geometric code if the number of points of degree one in the function field of genus three optimal curve over finite field with a discriminant {-19, -43, -67, -163} has the lower bound 12m/(m-3). Using an explicit calculation with the valuations of the pole divisors of the images of the basis functions x, y, z in the function field of the curve via the mapping λ, we have proved that the automorphism group of the function field of our curve is a subgroup in the automorphism group of the corresponding algebraic-geometric code. In the second theorem, it is proved that if m≥ 4 and n > 12m/(m - 3), then the automorphism group of the function field of our curve is isomorphic to the automorphism group of the algebraic-geometric code n associated with divisors ∑ Pi и mP∞, where Pi are points of the degree one.

Published: December 2022

In this paper, we address the problem of intrusion detection for modern web applications and mobile applications with the cloud-based server side, using malicious content detection in JSON data, which is currently one of the most popular data serialization and exchange formats between client and server parts of an application. We propose a method for building a JSON model for the given set of JSON objects capable of detection of structure and type anomalies. The model is based on the models for basic data types inside JSON collection objects and schema model that generalizes objects’ structure in the collection. We performed experiments using modifications of objects’ structures and insertions of code injection attack vectors such as SQL injections, OS command injections, and JavaScript/HTML injections. The analysis showed statistical significance between the model’s predictions and the presence of anomalies in the data gathered from the real web applications’ traffic. The quality of the model’s predictions was measured using the Matthews correlation coefficient (MCC). The MCC values computed on the data were close to one which indicates the model’s high efficiency in solving the problem of anomaly detection in JSON objects.
Low power assignment of partial states of a parallel automaton

Published: December 2022

The problem of a low-power assignment of the partial states of a parallel automaton is considered. A method to solve that problem is suggested that provides minimizing the number of memory elements in the implementing circuit of the automaton and minimization of their switching activity. The problem is reduced to finding a minimal weighted cover of a graph with its complete bipartite sub-graphs (bi-cliques).
Median for an odd number of linear order relations and its use in group choice problems
Authors:   Moscow Aviation Institute, Nefedov Victor N.
Published: December 2022

We consider the problem of constructing a median for an odd set of linear order relations defined on a finite set A = {a1,a2,..., an}, which is also sought in the class of linear order relations. We arrive at a similar problem when considering some group choice problems. The distance between binary relations is the Hamming distance between their adjacency matrices. In the case under consideration, the binary relation ρ, which has the minimum total distance to the given set of binary relations, is the median for these relations and, moreover, is unique. However, this median is not always transitive (and in this case is neither linear order, nor even a quasi-order), and therefore cannot be taken as a solution to a given problem. However, the median ρ necessarily belongs to the set LA[n] (of linear asymmetric binary relations on A), to which, in particular, all linear orders on A also belong. Some properties of binary relations from LA[n] are investigated. The concepts of “almost optimal” and Δ-optimal relations are introduced, which are linear orders and, at the same time, exact solutions of the stated problem. Algorithms for finding them are given, based on the obtained statements about binary relations from LA[n] and having polynomial computational complexity. An equivalence relation on the set LA[n] is considered, which allows one to divide this set into equivalence classes, the number of which Kn is much less than the number of elements in LA[n]. For example, |LA[5] | = 1024, K5 = 12. Thus, each binary relation from LA[n] is equivalent to exactly one of the Kn representatives of the equivalence classes and, therefore, has its main properties. But then the study of a wide class of problems can be reduced to considering a relatively small set of them. The process of finding the specified set of equivalence class representatives is illustrated for n = 2,3,4, 5. A method for solving the problem posed is also given, using the representation of binary relations in the form of graphs (the method of selecting the minimum sets of contour representatives in the median ρ), which has exponential computational complexity.

Authors: Figueiredo Ana Carolina Carvalho , Novaes Jaqueline Zanetti , Santos Guilherme Henrique dos
Published: December 2022

As mudanças climáticas globais são uma realidade e o crescimento populacional nas áreas urbanas as potencializam, ampliando a ocorrência de fenômenos tais como inundações nas cidades. Neste contexto as infraestruturas verdes podem ser adotadas, proporcionando maior interação entre cidade e natureza e minimizando impactos relacionados às modificações no clima tanto na escala local quanto global, sobretudo em áreas muito adensadas como é o caso de municípios da Região Metropolitana de São Paulo. Na cidade de Santo André- SP, a Zona de Reestruturação Urbana foi estabelecida pelo Plano Diretor em 2004, apresentando diretrizes para requalificação da paisagem e controle ambiental, propondo a ocupação de terrenos subutilizados ou não utilizados, e onde estão localizadas áreas identificadas como de alto risco a inundações.  Considerando tais apontamentos, são objetivos deste trabalho apresentar mapeamentos de espaços dentro da Zona de Reestruturação Urbana de Santo André em áreas com alto risco de inundação, onde possam ser propostas infraestruturas verde-azul para minimizar impactos urbanos relacionados às mudanças climáticas; bem como o estudo do atual estado da arte sobre as discussões do clima e do meio ambiente na Região Metropolitana de São Paulo. Considerando os objetivos levantados, foram utilizadas as metodologias de pesquisas bibliográfica e documental, além de estudos de caso. Os resultados esperados incluíram, após os mapeamentos, propostas para a implantação de infraestrutura verde-azul nos espaços mapeados e indicação de que a região tratada na cidade possui potencial efetivo como suporte à adaptação climática e sustentabilidade urbana.

Published: December 2022

O uso massificado de materiais plásticos nas últimas décadas, especialmente as embalagens de uso único, tem originado diversos impactos ambientais devido a lenta degradação. Visando reduzir e, posteriormente, substituir os materiais plásticos não biodegradáveis, muitas pesquisas têm sido realizadas para o desenvolvimento de materiais biodegradáveis nas últimas décadas. O presente trabalho tem por objetivo desenvolver uma revisão integrativa da literatura, por meio de critérios previamente estabelecidos. Para a busca de potenciais estudos escolheu-se as bases de dados bibliográficas eletrônicas Science Direct (Elsevier), Scientific Electronic Library Online (Scielo) e Web of Science (Clarivate Analytics). Os termos de busca empregados foram Composting, Extruded, Starch-based foams, Biodegradable polymers e Biodegradable materials, e as pesquisas foram realizadas no Resumo ou abstract. Determinou-se que seriam utilizados apenas publicações em revista na forma de artigos científicos, compreendendo o período: 01/01/2010 a 31/12/2020. A escolha do termo de busca Composting and Starch-based foams e a escolha da a base de dados Scielo, mostraram-se não ser adequadas para o objetivo do presente trabalho, visto que não foram encontrados resultados durante a etapa de busca. As ferramentas de busca disponíveis na base de dados Web of Science proporcionaram uma pesquisa mais consistente, por permitir a adição de mais condicionantes na busca. A partir da síntese e análise de estudos elegíveis considerados no presente trabalho, as propriedades mecânicas, a adição de agentes de reforço e a biodegradabilidade dos materiais, são condicionantes que recebem grande protagonismo e estão diretamente interligadas.

Hinduism and Prosthodontic Treatment: A Review and a Clinical Report of a Hindu Menopausal Woman
Authors: Spyridon Stefos
Published: December 2022

Hinduism is one of the world’s most populous religions. A matter in everyday dentistry is the use of products and materials that could limit dental treatment options because of religion. Menopause is a specific and critical period in a woman’s life when dental restorations or other dental procedures are needed. Some menopausal women face difficulty when performing dental care due to restrictions concerning their religion or vomiting symptoms. Religion and a hypersensitive vomit reaction in menopause may prevent the dental provider from choosing extended or complicated dental, mainly prosthodontic, treatment plans including bone grafts and dental implants, and consequently, these parameters can affect menopausal women’s quality of life. The purpose of this article is to review the current literature and to report a case of a 60-year-old Hindu menopausal woman, partially edentulous with an exaggerated vomiting reaction, focusing on successful clinical management using a simple but effective table salt technique for the gag reflex and proper fixed and removable prostheses design, as also to discuss how Hinduism affects the dental treatment plan, especially prosthodontic, because some products and their consistency used in dental implants and prosthodontics, are usually not acceptable due to this religion, affecting also menopausal womens’ quality of life. Because of the shift of population globally, the scientific community faces patients of different religions, faiths, traditions, and beliefs, and has to adjust socially to new conditions.
CNS-invasive aspergillosis following ibrutinib therapy
Authors: Matthew Kurian , Eric Vick , Dipen Khanapara
Published: December 2022

Ibrutinib is Bruton’s tyrosine kinase inhibitor that now become the standard of care for the treatment of CLL (chronic lymphocytic leukemia) and other lymphoid cancers. With its increasing usage, oncologists must become more aware of their potential side effect profile. Ibrutinib is typically thought to be less immunosuppressive than standard immunotherapy; however, can still cause devastating side effects. We present a case of CNS-invasive aspergillosis in a patient with Waldenstrom’s macroglobulinemia being managed with ibrutinib. We hypothesize that treatment with ibrutinib can resemble those with X-gammaglobulinemia, thus putting our patient at risk of developing such an invasive fungal infection. Traditional risk factors for CNS-invasive aspergillosis include neutropenia, systemic glucocorticoid treatment, mastoidectomy, spinal anesthesia and paraspinal glucocorticoid injections. Oncologists need to weigh the risks and benefits of ibrutinib therapy in certain populations and more data in the future may suggest potentially adding empiric antifungal coverage with its usage.

Introduction: Lumbar pain syndrome (LPS) is defined as pain or discomfort localized between the edge of the twelfth rib and the lower gluteal region, with or without spread to the lower extremities, and, depending on the etiology and degree of symptomatology, can have negative consequences and be one of the main reasons for work disability and absenteeism worldwide. The aim of this study was to determine the impact of exercise therapy on the activities of daily living of a person with LPS.
Methods: This prospective, longitudinal, and randomized controlled trial was conducted from June 2014 to June 2016. It included 200 subjects with symptoms of LPS, both sexes, aged 30 to 50 years, sedentary and standing occupations, randomized and equally divided into two groups: Examined (n = 100) and the control group (n = 100). In this study, the Oswestry Low Back Pain Disability Questionnaire was used after clinical examination.
Results: The percentage of disability according to the Oswestry disability index at the first examination was 31.78 ± 14.11% in the participants of the test group and 38.74 ± 17.48% in the participants of the control group (p = 0.002). After the second examination, the percentage of disability was 6.64 ± 3.15% in the test group and 23.92 ± 14.84% in the control group (p = 0.001). At the end of the examination, the percentage of disability was 2.36 ± 0.78% in the subjects of the test group and 13.82 ± 11.25% in the subjects of the control group (p = 0.001). A statistically significant difference was found in all three examinations, and the reduction in the percentage of disability was greater in the study group, p < 0.05.
Conclusion: The research conducted showed that motion therapy procedures focused on achieving natural spinal mobility and improving trunk muscle strength are effective in reducing
La toponimia en la lexicografía hispanolatina de Nebrija
Authors: Peña Arce Jaime
Published: December 2022

Este trabajo profundiza en la presencia de la toponimia en los textos mayores de la lexicografía hispanolatina de Nebrija, el Diccionario (1492) y el Vocabulario (¿1495?), tanto desde un punto de vista cuantitativo (número de ejemplos) como cualitativo (elemento descrito y localización de este). El objetivo final es establecer una comparación entre ambas realidades que permita perfilar las características propias de cada una de dichas obras. Los resultados evidencian que en el Diccionario la presencia de topónimos es muy superior y que estos aluden, fundamentalmente, a espacios que guardan relación con la historia y la mitología grecolatinas.
