KLASYFIKACJA DZIESIĘTNA W BIBLIOGRAFII POLSKIEJ. HISTORIA I STAN WSPÓŁCZESNY
Authors: MATCZUK ALICJA
Published: January 2021

Teza/cel – Celem artykułu jest próba przedstawienia zagadnienia stosowania klasyfikacji dziesiętnej w bibliografii polskiej w perspektywie historycznej i współczesnej. Zaprezentowane zostały fazy rozwojowe zachodzące na tym polu w kontekście zmian organizacyjnych i postępu technologicznego. Metoda – Zastosowano metodę: porównawczą, historyczną oraz analizy i krytyki piśmiennictwa. Wyniki/Wnioski – Badanie pozwoliło na wyróżnienie w historycznym rozwoju stosowania klasyfikacji dziesiętnej w bibliografii polskiej czterech okresów. Okres pierwszy, od początku XX w. do 1939 r. – rozwojem i promocją UKD oraz jej użytkowaniem w praktyce bibliograficznej zajmował się Instytut Bibliograficzny Towarzystwa Biblioteki Publicznej w Warszawie, następnie – ośrodki kształcenia bibliotekarzy i stowarzyszenia naukowo-techniczne, stosując klasyfikację w spisach bibliograficznych o charakterze oświatowym i technicznym. Okres drugi, od zakończenia II wojny światowej do połowy lat 60. XX w. – symbole UKD wprowadziła bieżąca bibliografia narodowa („Przewodnik Bibliograficzny”), bibliografia księgarska oraz przeglądy dokumentacyjne, które wykorzystywały klasyfikację również do prezentacji piśmiennictwa. Okres trzeci, od poł. lat 60. XX w. do końca lat 90. XX w. – proces kurczenia się zasięgu stosowania klasyfikacji na skutek rozwoju zautomatyzowanych systemów oraz powstania SINTO, w których UKD została pominięta w zestawie języków wyszukiwawczych; wyjątek stanowiło przyjęcie układu dziesiętnego w „Przewodniku Bibliograficznym” (wymóg międzynarodowy). Okres czwarty, od 2000 r. do dziś – układ według głównych działów UKD wprowadziła Biblioteka Narodowa do pozostałych członów polskiej bieżącej bibliografii narodowej. Bibliografie udostępnione są w formacie PDF. Wyszukiwanie za pomocą symbolu UKD oferują regionalne i lokalne bazy bibliograficzne stosujące program PATRON.

Teza/cel – Celem artykułu jest przeanalizowanie wpływu, jaki pandemia już wywarła na społeczną funkcję książki w dwóch perspektywach: podmiotów związanych z rynkiem książki oraz bibliotek. Metody badań – W artykule wykorzystano metodę analizy źródeł, tj. raportów i doniesień na bieżąco przedstawiających sytuację instytucji książki do połowy kwietnia 2020 r. Wyniki i wnioski – Na tej podstawie podjęto próbę wskazania trendów zmian, jednocześnie zastrzegając, że dogłębne omówienie długofalowych skutków pandemii będzie możliwe po upływie dłuższego czasu. Wśród tych zmian wymieniono m.in. działania prawne i finansowe, wspierające sektor książki. W ujęciu społecznym zwłaszcza wspólnototwórcza funkcja książki, jej udział w budowaniu relacji wewnątrz grup i społeczności, wydaje się być najbardziej zagrożona.

Fredholm eigenvalues and quasiconformal geometry of polygons
Authors: Krushkal Samuel
Published: January 2021

An important open problem in geometric complex analysis is to establish algorithms for the explicit determination of the basic curvilinear and analytic functionals intrinsically connected with conformal and quasiconformal maps, such as their Teichmüller and Grunsky norms, Fredholm eigenvalues, and the quasireflection coefficient. This is important also for the potential theory but has not been solved even for convex polygons. This case has intrinsic interest in view of the connection of polygons with the geometry of the universal Teichmüller space and approximation theory.
This survey extends our previous survey of 2005 and presents the newapproaches and recent essential progress in this field of geometric complex analysis and potential theory, having various important applications. Another new topic concerns quasireflections across finite collections of quasiintervals (to which the notion of Fredholm eigenvalues also can be extended).

Asymptotic estimates for the best uniform approximations of classes of convolution of periodic functions of high smoothness
Authors: Serdyuk Anatolii , Sokolenko Igor
Published: January 2021

We find two-sided estimates for the best uniform approximations of classes of convolutions of $2\pi$-periodic functions from a unit ball of the space $L_p, 1 \le p <\infty,$ with fixed kernels such that the moduli of their Fourier coefficients satisfy the condition $\sum\limits_{k=n+1}^\infty\psi(k)<\psi(n).$ In the case of $\sum\limits_{k=n+1}^\infty\psi(k)=o(1)\psi(n),$ the obtained estimates become the asymptotic equalities.
On nonhomeomorphic mappings with the inverse Poletsky inequality
Authors: Sevost'yanov Evgeny , Skvortsov Serhii , Dovhopiatyi Oleksandr
Published: January 2021

As known, the modulus method is one of the most powerful research tools in the theory of mappings. Distortion of modulus has an important role in the study of conformal and quasiconformal mappings, mappings with bounded and finite distortion, mappings with finite length distortion, etc. In particular, an important fact is the lower distortion of the modulus under mappings. Such relations are called inverse Poletsky inequalities and are one of the main objects of our study. The use of these inequalities is fully justified by the fact that the inverse inequality of Poletsky is a direct (upper) inequality for the inverse mappings, if there exist. If the mapping has a bounded distortion, then the corresponding majorant in inverse Poletsky inequality is equal to the product of the maximum multiplicity of the mapping on its dilatation. For more general classes of mappings, a similar majorant is equal to the sum of the values of outer dilatations over all preimages of the fixed point. It the class of quasiconformal mappings there is no significance between the inverse and direct inequalities of Poletsky, since the upper distortion of the modulus implies the corresponding below distortion and vice versa. The situation significantly changes for mappings with unbounded characteristics, for which the corresponding fact does not hold. The most important case investigated in this paper refers to the situation when the mappings have an unbounded dilatation. The article investigates the local and boundary behavior of mappings with branching that satisfy the inverse inequality of Poletsky with some integrable majorant. It is proved that mappings of this type are logarithmically Holder continuous at each inner point of the domain. Note that the Holder continuity is slightly weaker than the classical Holder continuity, which holds for quasiconformal mappings. Simple examples show that mappings of finite distortion are not Lipschitz continuous even under bounded dilatation. Another subject of research of the article is boundary behavior of mappings. In particular, a continuous extension of the mappings with the inverse Poletsky inequality is obtained. In addition, we obtained the conditions under which the families of these mappings are equicontinuous inside and at the boundary of the domain. Several cases are considered: when the preimage of a fixed continuum under mappings is separated from the boundary, and when the mappings satisfy normalization conditions. The text contains a significant number of examples that demonstrate the novelty and content of the results. In particular, examples of mappings with branching that satisfy the inverse Poletsky inequality, have unbounded characteristics, and for which the statements of the basic theorems are satisfied, are given.

Importancia de la gestión regional del saneamiento: el paradigma del Estado de Santa Catarina en el uso del subsidio cruzado
Authors: Victor Marcos Haneron , Santa María Bessy Castillo
Published: January 2021

Este artículo pretende demonstrar la importancia del subsidio cruzado para la gestión de los servicios de saneamiento y la implementación de políticas públicas relacionadas, permitido por la administración regional. Tratase de un modelo – mayoritariamente aplicado en Brasil – que se encuentra amenazado por privatizaciones y municipalizaciones de sistemas superavitarios, además por la falta de una percepción legislativa para una revisión de la titularidad, que en Brasil es deferida a los municipios en regla general (la excepción de regiones metropolitanas y aglomerados urbanos sigue sin reglamentación). Investigación metodológica de enfoque cualitativo, paradigma socio crítico y estudio de caso, que pasa por el escenario internacional con soportes de autores como Bel (2019), Borja-Vega y Kloeve (2018), Helm (2019), y sustentada por paradigmas sudamericanos presentados por Bonifaz Fernández y Montoya (2013), Casa (2013), y Ceppi (2014), además de los nacionales como Paludo y Borba (2014), Borja (2014), Cruz y Ramos (2016), Souza y Costa (2016) y Brown et al. (2016). En conclusión la quiebra del modelo solidario de subsidio entre ciudades ya es una realidad brasileña, especialmente en el Estado de Santa Catarina (Brasil), y que los ejemplos locales de privatización no han evidenciado éxito diferencial, exigiendo un reposicionamiento estratégico del mismo para que la universalidad del acceso a los servicios de saneamiento, con modicidad tarifaria, sea una realidad tangible.

The Socio-Political Enigma: The State
Authors: Onder Izzettin
Published: January 2021

The state is a multifaceted administrative-political organization that has various functions in different economic systems. Therefore, a simple definition for the state cannot be given in the face of its different role in different economic systems as well as the polymorphic  nature it displays to fulfill its capital accumulation function in capitalism. Confined to its role in the capitalist system, two main functions of the state can be discerned: contribution to capital accumulation and legitimization of the system. That the state needs tax revenue to perform its duties makes it necessary for the state to favor capital to foster economic activity. However, the process of capital accumulation gives rise to “public nuisance” and social harm to some groups in the society. To have a peaceful society and secure a social and political system, the second function of the state takes over the job of putting some measures in effect to legitimize the system. Thus, the state is burdened by two opposing and mutually exclusive public functions that are badly needed in capitalism to have a relatively healthy society. Therefore, the state appears as if it is an enigma in terms of its various functions in different systems and polymorphic nature, especially in capitalism.

Küresel bir salgına dönüşen Covid-19 virüsü yalnızca sağlık krizi değil, ekonomik ve politik krizlere de dönüşmektedir. Küreselleşme seviyesi salgını küresel salgın (pandemi) haline hızla getirmiştir. Covid-19 virüsü, II. Dünya Savaşı’ndan sonra yaşanan en büyük küresel ekonomik krize dönüşme tehlikesini beraberinde getirmiştir. Salgınla mücadelede oluşturulacak politikalar, ülkelerin ekonomik süreçlerini çok önemli oranda etkileyecektir.

Salgının ekonomik etkisini daha ayrıntılı incelemek, ekonomi politikası için önemli bir referans olacaktır. Bu çalışmanın amacı, Covid-19 virüsünün Mersin’de 2020 yılının Nisan ve Mayıs aylarında hanelerin ekonomik etkilerini incelemektir. Bu çalışmada internet ortamında 1058 hane ile anket yapıldı. Ankete Katılanların %40’ını (421 hane) Mersin’de yaşayan haneler oluşmaktadır. Aynı zamanda toplam 55 farklı ilden katılımı sağlandığı için Mersin ilinin diğer illerle karşılaştırma imkânı sağlamaktadır.

Yapılan analiz sonucu, Mersin ilinde Covid-19 sonrası hanelerin %55,1’inde gelir kaybı olduğu belirtilmiştir. Covid-19 öncesi Mersin’de geniş işsizlik oranı yaklaşık %23 olarak hesaplanırken, Covid-19 sonrası bu oran %33,3’e yükselmiştir. Mersin ilindeki Covid-19 sonrası işsizlik artışı ankete katılan diğer iller ortalamasından daha yüksek olmuştur. Pandemi ile birlikte, istidamın önemli oranda yükünü taşıyan KOBİ’lerle ilgili yeni ekonomik paketlerin açıklanması işsizlikle mücadelede ciddi destek olacaktır. Bu desteklerin, özellikle istihdam yükünü artıracak sektör ve bölgelere göre farklılaşması, pandemi sonrası ülkede resesyon riskini de azaltabilir.

Bu çalışmada Türkiye Denizcilik İşletmeleri Genel Arşivi’nde bulunan Şirket-i Hayriye’nin Hasköy Tersanesi çalışanlarına ait 1929-1944 yıllarını içeren “mezuniyet” ve “hasta” defterlerindeki verilerden yararlanarak tersane işçilerinin en çok maruz kaldıkları hastalıklar ve bunlardan en çok hangi meslek mensuplarının etkilendikleri; meslekler ve hastalıklar arasındaki ilişki tespit edilmeye çalışılmıştır. Bu hastalıkların hangilerinin “meslek” hastalığı olarak değerlendirilebileceği üzerinde de durulmuştur. Hastalıklar yanı sıra Hasköy Tersanesi çalışanlarının iş kazalarına da uğradığı bilinmektedir. Bu bağlamda hangi meslek grubundan olan işçilerin daha çok iş kazalarına uğradıklarına da bakılmaktadır. Hastalıklar ve iş kazalarının yanı sıra Şirket-i Hayriye’nin iş yeri hekimliği uygulamasına da dikkat çekilmeye çalışılmıştır.
Using MLT To Estimate Corruption Patterns From The BEEPS
Authors: Shemetev Alexander
Published: January 2021

The paper describes the opportunity for using machine learning technologies (MLT) for estimating corruption by clustering. We used the enhanced BEEPS data (The Business Environment and Enterprise Performance Survey (European Bank for Reconstruction and Development, 2014)). It contains 1672 variables and 59619 observations produced by well-respected agencies like Nielsen for the European Bank of Reconstruction and Development. The analysis of different indicators with the MLT allows us to cluster the countries by the types of potential corruption patterns. We suggested this method could overcome the shortcomings of the classical survey surveillance approach because we can estimate countries with some distortion or insufficiencies in the data (for example, when the business units may want to lie about the corruption due to some reasons). This gives us an additional measurement that can be used for analyzing the true corruption field. This can be useful for business units, scientific people, and policymakers for analyzing the patterns of corruption in different countries.
INFRARED THERMOMETRY OF PARATHYROID GLANDS DURING THYROIDECTOMY FROM THE POSITION OF PREDICTING THE DEVELOPMENT OF POSTOPERATIVE HYPOPARATHYROIDISM

Objective: to study the results of intraoperative infrared thermometry parathyroid glands to assess their functional status after performing thyroidectomy with the position of predicting the development of postoperative hypoparathyroidism. Materials and methods. The work was a prospective controlled study, which included 54 patients after thyroidectomy performed for benign thyroid diseases. The average of 50.4 ± 3.8 years. Indications for surgical treatment: in 19 patients - nodular non-toxic goiter with compression of the organs of the neck; in 17 - nodular toxic goiter; in 18 - Graves disease. From the study were excluded patients with a relapse after previously completed surgery. For intraoperative thermometry we used a infrared thermometer CEM®ThermoDianostics (production of JSC «CEM-technology»). The thermometry was performed sequentially, starting from the top right and finishing with the left lower parathyroid gland after thyroidectomy. For the initial level compare temperatures were taken temperature thyroid tissue. Results. When conducting the thermometry of thyroid tissue before the start of mobilization, the average level of temperature was 36.5[35; 37.5]°C. the Average temperature of the parathyroid glands was on average 2±0,5°C lower than this figure. When comparing the performance of intraoperative determination of PTH level with the data of thermometry it turned out that the decrease in the average temperature of the parathyroid glands less than 2°C, led to significant disruption of their function, which is confirmed by the results of intraoperative determination of PTH, and decrease in temperature by more than 2.5 - 3°C was a prognostic factor of postoperative hypocalcemia, which was registered in 4 patients.

Introduction: Among the specific complications of operations on the organs of the neck, the main place is occupied by a violation of the mobility of the vocal cords. Thanks to the introduction of non-invasive methods for recording a signal from the vocal folds using intraoperative neuromonitoring (IONM), it became possible to assess the preservation of the laryngeal nerves, to avoid the development of bilateral paresis of the vocal cords, by assessing the preservation of nerves during the operation. Objective: to develop a methodology for the implementation of intraoperative neuromonitoring during video endosurgical operations on thyroid gland. Materials and methods: On the basis of the surgical department No. 1 of the Central Clinical Hospital, Administrative departments of the President of the Russian Federation, Clinic of Faculty Surgery and Oncology, Saratov State Medical University V.I. Razumovsky” during May 2013-April 2020, 412 patients with various pathologies of the thyroid glands underwent videoendosurgical interventions. Results: We performed the following surgical interventions for thyroidectomy - 112, hemithyroidectomy - 145, subtotal resection - 47 cases. The volume of the thyroid gland was from 17 to 200 ml. At the same time, we try to adhere to a certain algorithm of actions, taking into account the fact that during the operation, irritation of the laryngeal nerves can cause a variety of problems that will give an incorrect answer to these reasons: anesthesiology factors, incorrect operation of the active electrode, technical errors of the operation itself. Conclusions: Intraoperative neuromonitoring for videoendoscopic interventions provides the ability to visualize all anatomical structures incomparable with open operations, reduces the risks of trauma to the laryngeal nerves, allows you to monitor the signal in real time, improves the quality of intraoperative navigation and the safety of surgical intervention.
