Authors: Nosova M. A. , Volova L. T. , Sharov A. N. , Trunin D. A. , Postnikov M. A.
Published: June 2021

Relevance. Gingival recession is the apical migration of the gingival tissues associated with the exposure of the roots and alveolar bone loss. The prevalence of single recessions in people over 18 years old is 86.7% whereas multiple recessions, i.e. where all teeth are affected, amount up to 28.6%. High prevalence of the pathology necessitates improvement of the approach and tactic of multiple recession treatment in patients with different phenotypes. Nowadays, the use of autograft is the gold standard of multiple recession treatment. However, the technique has its drawbacks. The purpose of the present work was to assess the response to surgery and evaluate the final result of multiple recession treatment in one subject where the combination of autogenic and allogenic grafts was used in the same study design.

Materials and methods. The paper presents and describes a clinical case where auto- and allografts were used in one patient to treat multiple gingival recessions.

Results. All parameters of the gingival recession assessment showed comparable clinical benefit in all sites of autograft and allograft (dura mater) application. The root coverage was more than 80% around 13 teeth and less than 80% around 11 teeth.

Conclusion. The results of the autograft and allograft (dura mater) application were comparable, response to surgery was the same; besides, the allograft (dura mater) is attractive for combined and independent use during surgical treatment of multiple and especially full-mouth recessions.
The effective treatment of tooth sensitivity and adherence: two sides of the same coin
Authors: Iordanishvili A. K.
Published: June 2021

Relevance. Oral hygiene is of primary importance in the prevention and treatment of tooth sensitivity. Modern oral care products can significantly contribute to the treatment of tooth sensitivity and prevention of its recurrence. Aim – to assess the effectiveness of tooth sensitivity treatment, taking into account the adherence while using a new remineralizing gel manufactured in Russia.

Materials and methods. We evaluated the effectiveness of the tooth sensitivity treatment, satisfaction of 45 patients with the treatment and their adherence to the oral care routine. Group 1 used a special toothpaste ASEPTA "PLUS REMINERALIZATION" twice a day. Group 2 also applied a new remineralizing gel ASEPTA for two minutes after brushing.

Results. The treatment of tooth sensitivity was effective and ranged between 39.46% and 95.56% during the study. The effectiveness of tooth sensitivity treatment and satisfaction with oral care products were inversely associated with the patient adherence to the medical recommendations. Most patients partially (25% to 50%) adhered to the professional recommendations throughout the study.

Conclusion. The tested Russian oral care products effectively prevent tooth sensitivity. During the professional care visit, a dentist or a dental hygienist should pay more attention to increasing patient adherence to the recommendations of a dental professional.

Relevance. Currently, there are several basic techniques for the dental implant surface structuring. Laser treatment is an extremely promising technique for the surface structuring. This technology allows creating regular implant surface without using chemicals and in just one technological step. The purpose was to present study aimed to compare and evaluate in vivo the stability and osseointegration of dental implants with 2 different surfaces structured by ytterbium-doped pulsed fiber laser operating at 1064 nm.

Materials and methods. 60 dental implants were placed in the study. 2 types of dental implant surfaces, namely holes and parallel grooves, were created by the ytterbium laser operating at 1064 nm. A polished dental implant (without laser surface structuring) was also included in the experiment for comparison. The study was carried out on 15 laboratory animals (male rabbits, weight 3.5-4 kg). The implants were placed in the tibia. 4 implants with different surface types but of the same diameter and length were placed in each rabbit.

Results. Laboratory animals were sacrificed 1.5 and 3 months after the surgery. The stability of the implants was assessed by RFA (Resonance Frequency Analysis), based on the registration of resonance electromagnetic oscillations of the implant and the surrounding bone when they are exposed to the electromagnetic field (Osstell ISQ). Also, nondecalcified bone blocks were histologically examined using a confocal laser scanning microscope (Carl Zeiss LSM 780) and histomorphometry was performed (BIC-index: Bone-to-implant contact). Bone blocks were prepared according to a special technique: they were soaked and embedded into the plastic and synthetic resin. The obtained blocks were cut into sections, 40-50 µm thick, and stained with toluidine blue.

Conclusion. Laser surface structuring of the dental titanium implants is a promising technique. 59 in 60 (98.3%) implants were osseointegrated, there were no signs of inflammation in the bone tissue. The present results allow further studying of dental implants with various surface designs, structured by ytterbium laser.
Predictions of airborne noise between unit cabins by developing a cavity transfer matrix
Authors: Jung Jae-Deok , Hong Suk-Yoon , Song Jee-Hun , Kwon Hyun-Wung
Published: June 2021

The unit cabin has been used to construct internal ship space for improved efficiency and to reduce budgetary costs in shipbuilding. Because the cavity is placed between unit cabins, the noise of one room is transmitted through the sound insulating panel, the cavity, and the opposite
sound-insulating panel. In this study, by developing a transfer matrix of the cavity between structures, airborne noise between unit cabins was predicted. A sandwich panel, which is usually used in ships, was employed to construct a double panel, and the sound insulation performance was confirmed
by changing the thickness of the cavity. To improve the reliability of numerical results, they were compared with those from experiments conducted. The results showed that as the cavity size increases, the overall sound insulation performance improves. A parameter study was also conducted
on the density, Young's modulus, thickness, and thickness ratio of the core of the sandwich panel. To improve the sound insulation performance, increasing the density of the core is preferable to increasing the core thickness. The panel thickness ratio should be increased to avoid performance
degradation as a result of the resonance frequency.
Substitution of Fishmeal with Black Soldier Fly Hermetia illucens Linnaeus, 1758 Larvae in Finfish Aquaculture – A Review

Published: June 2021

The reliance of aquaculture feed industry on fishmeal has been challenged by ecological, economic, and ethical limitations leading fish nutritionists to look for viable alternatives, and conventional animal-based protein sources showed varying degrees of success in this regard. However, a non-conventional protein source, black soldier fly Hermetia illucens Linnaeus, 1758 larvae (BSFL), received due attention as a focal point in fish nutrition research. Though many studies were conducted on H. illucens as a potential protein source for fish, a comprehensive review is not available. Therefore, this article aims to review the existing literature on the use of BSFL as a fishmeal replacer in aquaculture. The nutrient composition of BSFL varied with the developmental stage and the composition of growing medium. High crude protein levels (40.4–56.2 %) and high crude fat levels (4.8–24.8 %) made BSFL suitable for high protein and high energy diet. Early prepupa was the best stage for harvesting, considering its high crude protein content and dry matter yield and less chitin content. Up to 100 % inclusion levels of BSFL meal were tested in a wide range of fish species. Most studies revealed that up to 50 % of fishmeal replacement would be possible without negative effects on the fish. Notable adverse effects were found beyond 50 % of fishmeal replacement, mainly due to high chitin levels in the pupal stage and high crude fat levels. Harvesting BSFL before the pupal stage and defattening made it possible to replace 100 % of fishmeal without adverse effects on fish.
On Possible Macro Consequences of Society Aging: Economic and Statistical Analysis on the Basis of National Transfer Accounts
Authors: Nazarova A. G.
Published: June 2021

The article discusses research results of socio-economic challenges in modern society using selected international statistics and presented in the format of National Transfer Accounts (NTA) as a follow-up to the author’s prior publications in the journal «Voprosy Statistiki» (Issues 4 and 11 of 2019; Issue 5 of 2020). Introduction to the article rationalizes the subject matter topicality both given the pressing problem of ageing of modern society and in connection with the necessity of practical adoption of National Transfer Accounts in the system of Russian statistics as a coherent derivation and elaboration of the System of National Accounts (SNA), expanding analytical capabilities of statistics. Going into the main part of the article, the author applies statistical methods to explore the key macroeconomic consequences of the global ageing of modern societies. The article provides evidence that macroeconomic challenges and risks to sustainable development emerge primarily in the countries featuring low birth rates, a high share of seniors, and significant levels of government support to the households. The author studies how shifts in the population age distribution translate into changes in consumer spending and incomes. The article presents and analyzes initial findings of the quantitative evaluation of these correlations based on historical data on healthcare expenditures and per capita labor income. The paper identifies the factors and the extent of their impact on how people choose the economic behavior model that ultimately determines the volume and structure of consumption in high inflation economies. Finally, the article lays down a number of conclusions to the following essence: (1) empirical estimates confirm the hypothesis that ageing society presents a heavier «economic burden» for the government finances rather than for the economy as a whole and (2) further advances in macro-statistic work (SNA core sections, National Transfer Accounts, satellite accounts within SNA) become increasingly important for expanding analytical capabilities required to seek for a more effective mechanism to build-up and utilize national resources in the face of population ageing.
Public Spending on Education and Economic Growth: Cross-Country Analysis
Authors: Kolosnitsyna M. G. , Ermolina Yu. E.
Published: June 2021

This paper aims to identify the relationship between public spending on education and GDP in two groups of countries: members and non-members of the OECD, based on statistical and econometric methods, including the methodology for international comparative analysis. The two selected groups of countries differ in their level of economic development: the OECD, the so-called ‘rich countries club’, and the second group, relatively low-income developing countries. The first part of the article deals with theoretical and information and methodological issues related to research on the relationship between educational development and economic growth, in particular the general theory of human capital investment, human capital in endogenous growth models, principles for empirical estimates of the relationship between education spending and economic growth. In the second part of the article, were tested the hypotheses concerning key factors of economic growth. The authors based them on studied theoretical sources, empirical works, and the proposed statistical base of empirical calculations. The paper substantiated the degree of impact of various factors using different groups of countries as an example. Based on panel data for 1995–2018, we estimate econometric models of the relationship between GDP and education expenditures, using time lags. The results confirm the positive impact of total education spending on GDP in the long term. However, the results differ for the two groups of countries. While in rich countries, investment in all levels of education has a positive impact on GDP, in poor countries, only primary education has a positive return, while spending on secondary and vocational education reduces GDP. This may be due to the lack of demand for high-level education in economies with poorly developed technologies and labor markets. As conclusions, the authors formulate proposals of a managerial and methodological nature regarding the need to consider the country’s development level in its educational policy and choose investment directions that are adequate to the current needs of the economy. In countries with a low level of development and a low level of education for the majority of the population, diverting public resources to finance professional education may slow economic growth in the short term. Conversely, increased coverage of mass primary education may contribute to rapid growth in the near future.
International Energy Reserves Accounting System: Harmonization of Statistical Information for SNA Purposes
Authors: Simonova M. D.
Published: June 2021

The article covers the study of several international and foreign information and methodological standards and documents on energy resources statistics. It also examines the possibilities of harmonizing energy resources statistics with the System of National Accounts (SNA). The relevance of the problems is determined by the need for further development of the Russian system of environmental-economic accounting and, in particular, of statistics on energy reserves, adaptation of international standards and best practices in this area in some foreign countries. International standards and foreign methodological documents are characterized in the context of ensuring international comparability of energy resources assessment and compilation of environmental-economic accounts for the SNA. Since the ongoing adaptation of environmental-economic accounting will be completed shortly, a compilation of Mineral and Energy Resource Accounts is also a vital activity of statistical offices. To adequately integrate them into the SNA, indicators of proven resources should be estimated in value terms. The implementation of these approaches will in turn lead to a statistically correct valuation of natural capital and the inclusion of these data in the SNA. However, prices for capital valuation can be applied, on the basis of the disaggregation of statistical indicators, exogenous extraction factor, as well as analysts' forecasts. The harmonization of statistical information on energy reserves on the conceptual basis of national accounting will ensure international comparability of the indicators under consideration as well as will promote to the ecological orientation of sustainable economic development and green growth both in Russia and abroad.
Neo-Latin poetry of Ukraine: literary and stylistic syncretism
Authors: Lastovets Mariia , Myronova Valentyna , Koshchii Oksana , Korolova Nataliia
Published: June 2021

The article considers the literary and stylistic peculiarities of Neo-Latin poetry in seventeenth to eighteenth-century Ukraine. Latin poetry of that time is marked by variability and diversity of genres, for it logically continued the classical traditions and at the same time was influenced by the aesthetics and poetics of the Baroque due to the interlingual contacts. The Latin language was supposed to be the main criterion of the high style in a poetry. As for the genre peculiarities, Neo-Latin poetry tended to panegyrics as the literature "fashion" of that epoch, when the poets expressed their gratitude and admiration to the philanthropists, whereas the elegic poems were the part of poetic courses to illustrate the genre. It explains the freedom and fantazy which are present in panegyric poetry and classical canon which served for writing elegies. The period of the seventeenth to the eighteenth century was an absolutely disparate one in both the political and social life of Ukraine. Rapid development of events, dramatically changing realia and values shaped very special attitudes to life with the contemporaries, in particular with Kyiv intellectual poets who wrote a significant number of works in Latin. Analysis of these works enables to characterize the development of the Latin language in Ukraine and consider Neo-Latin poetry of Ukraine as a part of the Western European literary and language unity.

a credencial para votar en México se ha consolidado como el documento de identificación oficial de las y los mexicanos. La necesidad material de contar con esta para efectos de identificación y la regulación electoral estricta sobre su expedición han generado demandas legales de ciudadanos en las cuales se advierte una opción judicial por la maximización de derechos. El itinerario garantista de la credencial para votar como documento de identificación se observa aún más porque los justiciables fueron personas en situación de vulnerabilidad. En este artículo se exponen tres asuntos, a saber, el de quien estaba en situación de calle y no cumplía los requisitos para la expedición de su credencial, de quienes incluso no podían expresar su voluntad para solicitar el trámite y de quien tenía suspendidos sus derechos político-electorales. Esos asuntos muestran cómo es posible leer la construcción de la democracia en México a partir de los derechos.

Published: June 2021

Eri silk is one of the wild silk varieties which are mainly available in the north-eastern areas of India. It exhibits goodmechanical and thermal resistance properties. In this concern, the present study focused to develop a bi-layer knittedstructure made from Eri silk yarn as one side(next to skin) and on another side bamboo yarn knitted fabric. Similarly,Tencel knitted fabric was used instead of bamboo. Twenty-four bi-layer knitted fabrics were developed and thenanalysed for its thermal comfort property. The air permeability, and wick-ability were found to be higher and the thermalresistance was found to be higher for bi-layer plated interlocked knitted fabric made out of Eri silk compared to bambooand Tencel.
The modern pollen–vegetation relationship in Jammu, India: a comparative appraisal
Authors: Quamar Md. Firoze , Tiwari Pooja , Thakur Biswajeet
Published: June 2021

An understanding of the relationship between modern pollen and vegetation is a prerequisite for reconstruction of vegetation and climate change from fossil pollen records. We conducted palynological studies of thirty-five surface soil samples from the Jammu region of India, which revealed that Pinus, among the conifers (regional needle-leaved taxa), is over-represented in the pollen assemblage due to its high production and effective dispersal of pollen. Other coniferous and broadleaved (regional and/or extra-regional) taxa have comparatively lower values in the pollen assemblages, similar to the representation of subtropical deciduous forest elements (regional), as well as shrubby (regional and/or extra-regional) taxa. This inconsistency in the pollen assemblage could be due to long-distance transport of the former by wind and/or water from the higher reaches of the Himalayas, and also because the latter have an entomogamous pollination syndrome and are not high pollen producers. The recovered pollen assemblage presents a distorted picture of the extant vegetation; hence, caution should be exercised in interpreting fossil pollen records from the study area. Principal component analysis (PCA) shows variability in the distribution of pollen from different sites in the Jammu region, perhaps the result of transport (by wind and/ or water), altitude and/or edaphic factors of the Himalayan terrain. The study should improve our understanding of the modern pollen-vegetation relationship and aid further calibration and interpretation of fossil pollen records.

Eighteen Apis dorsata Fabricius summer honey samples collected from Prayagraj District (Uttar Pradesh) during the summer season were analysed for pollen content. A total of 43 pollen types belonging to 26 plant families were found in these samples. Five of the 18 honey samples were found to be unifloral; 13 were multifloral. In terms of frequency, pollen of Syzygium cumini, Azadirachta indica and Coriandrum sativum were recorded as predominant pollen types, 11 pollen types as secondary pollen types, 23 as important minor pollen types, and 38 as minor pollen types. The Asteraceae family showed the highest frequency of occurrence. Four pollen types were recorded in more than 50% of the honey samples: Ageratum conyzoides, Bombax ceiba, Azadirachta indica and Syzygium cumini. Absolute pollen type counts per 10 g of honey samples ranged from group II to group V. The aim of determining and evaluating the pollen data was to infer the flora visited by the honeybees during the summer season in Prayagraj District. The findings were correlated with the pattern of vegetation in the vicinity of the bee hive sites during honey production. The study indicates that Prayagraj District has good potential for beekeeping ventures, due to the high diversity of nectar- and pollen-producing taxa during the summer season.
El comercio justo en la universidad ecuatoriana
Authors:   , Vinueza Luna Jenny Lolita
Published: June 2021

La temática del comercio justo (CJ) es importante para Ecuador; en la última década el gobierno del país ha diseñado políticas públicas que lo apoyan. El problema de la presente investigación es que no se conoce cuál es el involucramiento de la universidad en esta temática y cómo podría contribuir al estudio y el desarrollo de esta modalidad de comercio. El objetivo es analizar la posición de la universidad sobre la problemática del CJ en el Ecuador. Se aplicaron diversas metodologías, el tipo de investigación es de carácter descriptivo con un enfoque mixto: cualitativo y cuantitativo, como técnica de recolección de datos se analizaron fuentes secundarias: 8 leyes relacionadas al comercio justo y 51 planes estratégicos de las universidades ecuatorianas; se realizaron entrevistas semiestructuradas a 14 stakeholders del comercio justo en Ecuador; así también se entrevistó a 358 docentes de las universidades de Pichincha y a 78 decanos de las carreras afines al comercio justo en Ecuador. Como conclusión se establece que los planes estratégicos de las universidades no contemplan tácitamente aspectos de CJ y que los docentes no están familiarizados con la temática; se establece una “balcanización” de las políticas públicas debido a la competencia entre ministerios y no existe una relación fuerte entre la universidad ecuatoriana y los stakeholders del CJ.
Análisis crítico multimodal de grafitis lingüísticos en la comuna de Ñuñoa post 18-O
Authors: Rosillo Villena Juan
Published: June 2021

Este trabajo analiza nueve grafitis lingüísticos cuyas imágenes fueron fotografiadas en las Avenidas Irarrázaval y Vicuña Mackenna comuna de Ñuñoa, Santiago de Chile, entre diciembre de 2019 y julio de 2020 con el objeto de determinar de qué manera expresan los grafitis seleccionados el discurso opuesto a la dominancia social en el marco del estallido social del 18 de octubre de 2019. Aplicamos un modelo dinámico de tres dimensiones de análisis compuesto por: a) el discurso contrario a la dominancia social, b) el paisaje sociosemiótico urbano de Ñuñoa y, c) el debate sobre el Estado y la Constitución chilena. El análisis considera tres niveles de construcción de significados, a saber: textual, co-textual y contextual, con énfasis en las funciones cognitiva y poética del grafiti, abordados desde el Análisis Crítico del Discurso Multimodal. Los resultados indican que el discurso opuesto a la teoría de la dominancia social analizado se manifiesta por medio de críticas hacia el sistema económico y político imperante, desafío hacia la autoridad y cuestionamiento a la naturalización de la jerarquía social plasmados en el paisaje de una comuna de clase media-alta en el marco de las protestas nucleadas alrededor de diversos movimientos sociales a favor de una reforma constitucional.
Posible asociación entre el apoyo a formas menos democráticas de gobierno y el miedo al delito: investigación longitudinal en Brasil, periodos 1990-1998 y 2005-2014
Authors: Pereira Pontes Filho Raimundo , Almeida de Andrade Dornelles Tatiana
Published: June 2021

Mediante una investigación longitudinal con datos del instituto World Values Survey, el presente artículo busca confirmar las siguientes hipótesis: 1. Hay una asociación positiva entre el miedo del crimen o la sensación de inseguridad y el apoyo a formas menos democráticas de gobierno; y 2. Las tasas de confianza en las instituciones democráticas se comportan en una asociación negativa con las tasas de apoyo a formas menos democráticas de gobierno. Sin embargo, no solo se refutaron ambas hipótesis, sino que los datos mostraron que las premisas en sí mismas eran inconsistentes con la realidad.
Aspectos teóricos y metodológicos para el análisis de revistas digitales de cultura y literatura. Nuevas geografías en el contexto argentino
Authors: Vigna Diego
Published: June 2021

La presente investigación, inscripta en la línea de aportes metodológicos para el estudio de publicaciones periódicas dedicadas a la cultura y la literatura, parte de una interrogante cada vez más problematizado en diversos campos disciplinares: cómo leer una revista. Aquí nos abocamos a revistas digitales de Argentina, partiendo de la evidencia de que todo lo construido sobre la tradición nacional de publicaciones impresas ha sido interpelado por la presencia del soporte digital en red y sus formatos, rutinas y hábitos de publicación. En este sentido, nos abocamos a la relevancia del objeto revista en su nueva materialidad, a partir de proyectos que nacieron en el ecosistema digital. Tomamos cinco casos representativos de revistas vigentes dedicadas a la literatura y la crítica cultural (Paco, Anfibia, Carapachay, Atletas y Humo), para delimitar dimensiones de análisis entre aspectos internos y externos de cada medio.
On totally global solvability of evolutionary equation with unbounded operator
Authors: Chernov A.V.
Published: June 2021

Let $X$ be a Hilbert space, $U$ be a Banach space, $G\colon X\to X$ be a linear operator such that the operator $B_\lambda=\lambda I-G$ is maximal monotone with some (arbitrary given) $\lambda\in\mathbb{R}$. For the Cauchy problem associated with controlled semilinear evolutionary equation as follows
\[x^\prime(t)=Gx(t)+f\bigl( t,x(t),u(t)\bigr),\quad t\in[0;T];\quad x(0)=x_0\in X,\]
where $u=u(t)\colon[0;T]\to U$ is a control, $x(t)$ is unknown function with values in $X$, we prove the totally (with respect to a set of admissible controls) global solvability subject to global solvability of the Cauchy problem associated with some ordinary differential equation in the space $\mathbb{R}$. Solution $x$ is treated in weak sense and is sought in the space $\mathbb{C}_w\bigl([0;T];X\bigr)$ of weakly continuous functions. In fact, we generalize a similar result having been proved by the author formerly for the case of bounded operator $G$. The essence of this generalization consists in that postulated properties of the operator $B_\lambda$ give us the possibility to construct Yosida approximations for it by bounded linear operators and thus to extend required estimates from “bounded” to “unbounded” case. As examples, we consider initial boundary value problems associated with the heat equation and the wave equation.
Bursa Ataevler Mahallesi'nin LEED ND Kriterleri Kapsamında İncelenmesi
Authors: ÇOBANER Bilgen
Published: June 2021

Ülkemizde
kentlerin hızlı gelişmesi sonucu yaşanan göçler ve kaliteli yaşam alanları
talebi sonucu köhnemiş ya da  rantı
yüksek olan bölgelerde kentsel dönüşüm çalışmaları gözlenmektedir. Bursa kenti  yapılaşmanın en fazla olduğu büyük
şehirlerimizdendir.  Bursa Ataevler
Mahallesi 1980-90 yıllarında yapılmış olup üst ve üst-orta gelir gruplarına
hitap etmekteydi.  Kentin batı ve kuzey
yönlerinde gelişmesi üst gelir gruplarını yeni yerleşim alanlarına
yönlendirdi.  Ataevler Mahallesi kent
merkezine ve yeni yerleşim alanlarına toplu taşıma ve otomobillerle olan
ulaşımının kolay olması sebebiyle değerli bir alandır.  Bu sebeple kentsel dönüşüm sürecine
girmiştir.  Henüz tüm mahalle
dönüştürülmemiştir. Bu sebeple mahallenin kent için katkısı eski ve yeni
halleri ile birlikte incelenmiştir.Kente
bütüncül bir yaklaşım ile yaklaşılması gerekmektedir.  Aksi taktirde Ataevler Mahallesi örneği gibi
yeni yerleşim alanı olarak nitelendirebileceğimiz yerler bu şekilde kentsel
dönüşüm uygulamalarına maruz kalmaktadır. 
Bu sebeple sürdürülebilir mahalle tasarımları olması gerekmektedir.  Ülkemizde mahalleler için bir
sürdürülebilirlik kriteri bulunmamaktadır. 
Bu sebeple Amerika'da uygulanan LEED sürdürülebilirlik kriterleri
ülkemizde baz alınan en yaygın sertifika sistemidir. Ataevler Mahallesi de yarı
yeni yarı eski dokusu ile birlikte LEED Neighbourhood Development (LEED ND)
kriterleri kapsamında incelenmiştir. 
Kriterler bireysel yapı bazında değil, bütüncül bir mahalle olarak var
olan hali ile incelenmiştir. Araştırmada çalışma alanının incelenmesi, mahalle
ve kentsel sürdürülebilirliğin mahalle ölçeğindeki yeri gibi kavramlar
açıklanmıştır; LEED ND kriterleri incelenmiş ve konuyla ilgili kriterler
açıklanıp ele alınmıştır. Çalışma alanından elde edilen bilgiler LEED ND
kriterlerine göre incelenmiş ve mahallenin var olan durumunun bu
sertifikalandırma sistemine göre sürdürülebilir olup olmadığı sonucuna
varılmıştır.

Authors: SAVRUN Burak , MUTLU Hanifi Murat
Published: June 2021

Dünya
nüfusunun büyüme hızı ve bireylerin daha iyi yaşam arzusu, istihdam ve kalkınma
arayışları v.b. nedenler, insanları kırsal alanlardan kentsel alanlara göçe
teşvik etmekte; bunun bir sonucu olarak kentleşme ve kent nüfusu ciddi artış
eğilimi göstermektedir. Bu eğilim mevcut kentsel problemleri daha da karmaşık
hale getirmektedir. Kent lojistiği, kentlerin ekonomik ve sosyal gelişimini
desteklerken, kentsel alanlarda yük ve yolcu taşımacılığına bağlı trafik
sıkışıklığı, gürültü, hava kirliliği ve enerji tüketimi gibi sorunları
azaltmayı amaçlamaktadır. Bu çalışma, ISI Web of Science ve Scopus veri
tabanlarının çevrimiçi versiyonlarından ‘‘city logistics’’ anahtar kelimesi ile
çalışma başlıklarında aranan kitap, makale ve konferans bildiri çalışmalarının bibliyometrik
analizini yapmayı amaçlamaktadır. Son yıllarda sosyal bilimler alanında sıkça
kullanılan bir araştırma yöntemi olan bibliyometrik analiz, yayınların yazar ve
makale sayısı, yazar profili, yayın yeri bilgisi, yıl, makale konusu,
araştırmanın amacı ve kaynak kullanımı gibi temel belirgin kriterleri
incelemektedir. Bibliyometrik analiz sayesinde çalışma, kent lojistiği
alanındaki araştırma eğilimlerinin belirlenmesi, bu alandaki araştırmaların
çeşitli yönlerinin tanınması ve aynı zamanda alandaki boşlukları tespit ederek
ilerleyen süreçte yapılması planlanan çalışmalara katkı sağlamayı hedeflemektedir.

Kentsel dönüşüm uygulamaları ilk defa, kentsel büyümeler sonucunda, eski yapıların yıkılıp yeniden yapılmasışeklinde, 19. yüzyılda İngiltere’de ortaya çıkmıştır. Zaman içerisinde çeşitli formlara evrilen dönüşüm projelerindeartık sürdürülebilir kentler yaratılarak dönüşümün sadece fiziki değil aynı zamanda sosyo-ekonomik ve kültürelboyutları da dikkate alınmaktadır. Türkiye’de ise kentsel dönüşüm süreci, sanayileşme sonucu artan iç göç ilekentlerde çarpık ve planlamaya uygun olmayan gecekondu bölgelerinin oluşumuna neden olmuştur. 2012 tarihindeyürürlüğe giren 6306 sayılı Afet Riski Altındaki Alanların Dönüştürülmesi Kanunu ile bu dönüşüm, sadece fizikidönüşümden ibaret kalmıştır. Bu çalışmada amaçlanan husus, dönüşümün gerekli olduğu yerlerde; bölgede yaşayanhalkın da fikirleri alınarak, tarihi dokunun korunduğu, doğa ve çevreyle uyumlu yaşam konseptleri yaratmaya katkısağlamaktır. Çalışmada, İstanbul’un tarihi merkezlerinden olan Üsküdar’da bir gecekondu bölgesi olan Selamsızsemti, halkın sosyolojik yapısını da dikkate alarak sürdürülebilir kentler yaratma önerisi kapsamındadeğerlendirilmiştir. Bu çalışmada “Dünyada yenilebilir kentlerde yapılan uygulamalar ile Selamsız semtinin tarihiyapısını koruyarak, halkın da beklentilerinin karşılandığı, mutlu bir yaşam konsepti nasıl elde edebiliriz?” sorusunacevap aranmıştır.
