Представленная эколого-экономическая оценка земель сельскохозяйственного назначения Республики Тыва разработана с учетом теоретических основ экономической оценки стоимости земель и методов стоимостной оценки экологически значимых факторов. По сельскохозяйственному и природно-экономическому районированию Восточно-Сибирского региона, Республика Тыва отнесена к степной овцеводческо-скотоводческой зоне. В целях более рационального размещения и научно-обоснованной специализации сельскохозяйственного производства территория Тувы разделена на 4 сельскохозяйственные зоны [1]. Сельскохозяйственные угодья района исследования входят в Центральную сельскохозяйственную зону преимущественно земледельческую подтайгу, животноводческо-зерновую степь, и в Западную сельскохозяйственную зону преимущественно животноводческо-зерновую. Это наиболее крупные, освоенные и густонаселенные части республики, где сосредоточена большая часть пахотных земель, 2/3 сенокосов и пастбищ, более 80% населения республики. Территории сельхозугодий находятся в пределах сухостепной, степной и лесостепной природно-климатических зон. Климат отличается наибольшей степени аридности. Основными типами почв на пахотных землях являются каштановые супесчаные почвы, подверженные ветровой эрозии – 60 %, черноземы – 23 % и аллювиальные дерновые почвы – 15 %. Выполненная оценка показывает, что общий ущерб от деградации почв для Центральной и Западной сельскохозяйственных зон республики оценивается более 3,5 млрд. рублей, что составляет около трети стоимости земель, относящихся к сельскохозяйственным угодьям республики. Выявлено снижение стоимости земель за период 2012 по 2022 гг. для Тандинского района – 54,1 % и Чеди-Хольского района – 47,2 %, что связано с деградацией почв.

Tourism is an important activity in urban development because it is able to increase economic factors that affect income increases, increase business and employment levels and reduce poverty, as well as one of the leading sectors that become income for the government. The success of tourism is easy to observe if there is an increase in the number of tourists who come from year to year. Location is a factor that greatly affects the increase in the number of tourists because a good location can increase the value of decisions in visiting tourist objects. This shows that the better the location, the higher the value of tourists' decisions in visiting tourist objects. Attractions have 4 development aspects in it which are called 4A aspects consisting of attractions, amenities, accessibility, and additional services. These aspects become benchmarks in seeing the offer of the location of a tourist attraction. The research was conducted with the aim of determining the location of the tourist attraction in Singkawang City based on the 4A aspect of the tourist attraction. This study uses a quantitative approach that uses spatial syntactic analysis to assess accessibility, and scores to generate findings. From the analysis, the results show that the tourist attraction in Singkawang City has sufficient value within the limits of possibilities and facilities that can be accessed at the tourist attraction.

Along with the development of the times, human life is also changing, the pattern of life and activities in every job that requires the community, especially big cities to be ready in prime condition. In carrying out daily activities, humans tend to use brain functions more than muscles, so humans are more likely to be lazy to spend more energy. This causes many people to experience obesity, stress, physically unhealthy etc. The purpose of the fitness center is to provide comfort with sports facilities provided for the community. The activities in the form of a gym, aerobics, yoga, swimming, jogging and several other sports that aim to train muscles and reduce weight, make the ideal body as desired. In planning a fitness center as a place for exercise and sports, the design must be in the form of a building with a large space. The application of green open space in the building can be applied to the garden in the building, with wide openings in each room so as to be able to take advantage of the ventilation sanded with vegetation to make the room feel comfortable and cool. This application is suitable for sports areas, because when doing sportsactivities the body requires smooth oxygen circulation. Destroyed ventilation with vegetation is also able to provide health for the body while exercising.

Exploring the possibilities of transhumanistic risk management
Authors: Vorontsova Yu. V. , Gil Martínez M. A.
Published: February 2023

The article considers the actual reflection of the transhumanistic concept in various fields of scientific knowledge. This concept has recently aroused genuine interest both because of its direction and because of its own contradictions. The discussion that has unfolded around this concept allows to evaluate all the pros and cons of the implementation of the transhumanist idea, which requires improving the physical condition of a person through the use of the most advanced technologies, among which biotechnology occupies an important place. Their use generates contextual social, economic and political problems. In this regard, it is necessary to investigate the process of emergence and development of transhumanistic risks, as well as the possibility of managing them on the basis of both traditional and original tools, taking into account the specifics of the transhumanistic approach. In the article, the authors present a study of the formation of transhumanistic risks associated with the creation and use of artificial intelligence, as well as the possibility of risk management in the transhumanistic space. The threat is increasing due to the growing globalization, interconnectedness and the speed of change in the world. These trends are generally useful, but present new challenges, including new types of transhumanistic risks associated with the use of artificial intelligence. It is more difficult to predict them than any other known risks. Conceptual options for assessing the situation developing in the transhumanistic space together represent a new vector transhumanistic risk management theory and practice development.
New sanctions of the European Union and United States against Russia and their impact on Tajikistan’s socio-economic development
Authors: Rakhmonov A. Kh.
Published: February 2023

The article examines the socio-economic relationship between Tajikistan and Russia, the new European Union and USA sanctions against Russia and their impact on the economy and well-being of Tajikistan, and the role of Society for Worldwide Interbank Financial Telecommunication (SWIFT) in Russian and Tajik banks, including the disconnection of SWIFT from Russian banks and its impact on remittances of migrant workers in Tajikistan. Attention is paid to Tajikistan’s crisis management policy. After gaining independence, Tajikistan’s economy suffered greatly from the civil war in the republic. Russia is one of the main donors to Tajikistan’s economy. There are countries that are more connected to Russia than Tajikistan, but it is difficult to find a country that could compete with Tajikistan in terms of dependence on Russia. Almost all sectors of Tajikistan’s economy depend on Russia: Tajikistan is a donor country for migrant workers, and remittances from migrant workers play an important role in Tajikistan’s economy. Only, at the expense of money transfers of Tajik labor migrants, the banking sector of Tajikistan is supported. Over the years of independence, Tajikistan has not taken its economy out of the influence of Russia. The dependence of the Tajik economy on Russia manifested itself in the very first days of the conflict actions on the territory of Ukraine in February 2022. After the statement of Western countries on the introduction of new sanctions to restrict the access of some Russian banks to the SWIFT, the problems of the financial intermediation market of Tajikistan were exposed. An unprecedented package of sanctions by Western countries due to the situation with Ukraine has already led to a number of problems inside Tajikistan. European Union and USA sanctions against Russia have also had a strong impact on all sectors of Tajikistan’s economy, from food prices to the banking sector. The aim of the article is to assess the role of the new European Union and USA sanctions against Russia in connection with the conflict in Ukraine and their impact on the economy and welfare of Tajikistan.
Review of global and Russian trends in the hydrogen energy development
Authors: Vechkinzova E. A. , Steblyakova L. P. , Sumarokova E. V.
Published: February 2023

In the article, based on a comparative analysis and analytical generalization of publications, program and regulatory documents from different countries, the authors consider the prospects for the development of the hydrogen market. Most publications are currently focused on the technical and technological aspects of hydrogen energy, solving the problem of increasing the efficiency of methods for the production, transportation, distribution and storage of hydrogen fuel. In all countries of the world, the technology for the production of highly environmentally friendly “green” hydrogen is at an early stage, which makes it highly dependent on government initiatives to develop hydrogen projects and government funding of both scientific research in this area and ongoing projects. Peaks of interest in the field of hydrogen energy are associated with changes in the fossil energy markets, which makes the development of this technology unsustainable. Many countries are ready to invest in the development of hydrogen energy, and, given the growth in demand for hydrogen, are ready to export it at an affordable price. The results of the study indicate that the trends in the development of hydrogen energy in Russia are fundamentally aligned with global trends. At the same time, the high resource and scientific and technological potential allows Russia to fully focus its strategy on its implementation, not only developing the domestic market, but also acting as an exporter of hydrogen and expanding international cooperation in this area.

Authors: Bonyani A. J.
Published: February 2023

The article is devoted to the analysis of scientific approaches to the staff motivation and incentive systems in contemporary conditions. The dynamically developing world poses ever new challenges for mankind. They can be solved only with professionally formed human capital. Therefore, the author presents in the article an analysis of the existing types and forms of personnel motivation and incentive systems, and also highlights the factors of the modern world that dictate the introduction of new tools and methods for motivating employees of enterprises. Such factors are digitalisation processes that require the acquisition of new competencies in this area not only for specialists and management personnel, but also for workers involved in the production of tangible products and the provision of services. Another equally important factor is the crises (financial, political, pandemic, military actions, etc.), which have occurred several times over the past twenty years, and under these conditions, managers and business leaders are forced to change approaches and make changes to existing employees’ motivation systems. The conducted research can be reflected in the development of systems for motivating and stimulating personnel in modern conditions.

Published: February 2023

BACKGROUND: Emergence of new pathogenic viruses along with adaptive potential of RNA viruses has become a major public health concern. Hence it becomes even more important to explore and evaluate the antiviral properties of nanocomposites which is an ever-evolving field of medical biology. METHODS: In this study, series of metal/metal oxide (Ag/NiO : NiO, AN-5%, AN-10% and AN-15%) and ternary metal oxide nanocomposites (Ag2O/NiO/ZnO : N/Z, A/N/Z-1, A/N/Z-2 and A/N/Z-3) have been synthesized and characterized. Cellular uptake of nanocomposites was confirmed by ICP-MS. RESULTS: Intriguingly, molecular docking of metal oxides in the active site of nsP3 validated the binding of nanocomposites to chikungunya virus replication protein nsP3. In-vitro antiviral potential of nanocomposites were tested by performing plaque reduction assay, cytopathic effect (CPE) analysis and qRT-PCR. The nanocomposites showed significant reduction in virus titre. Half-maximal inhibitory concentration (IC50) for A/N/Z-3 and AN-5% were determined to be 2.828 and 3.277 g/mL, respectively. CPE observation and qRT-PCR results were consistent with the data obtained from plaque reduction assay for A/N/Z-3 and AN-5%. CONCLUSION: These results, have opened new avenues for development of nanocomposites based antiviral therapies.

Published: February 2023

The direct catalytic hydrocarbylation of readily available amino acids with halohydrocarbons is one of the most straightforward methods leading to disubstituted non-proteinogenic amino acid compounds. However, all the re-ported methodologies depend on N-protected amino acids as starting materials. Herein, we report on three highly efficient aldehyde-catalyzed direct hydrocarbylations of N-unprotected amino acid esters with aryl-, allyl-, and benzyl halides. By promoting a simple chiral BINOL-aldehyde catalyst or combining catalysts of a chiral aldehyde and Lewis acid ZnCl2, the asymmetric arylation, allylation, and benzylation of amino acid esters with the corresponding halohydrocarbons proceed smoothly, producing disubstituted amino acids in moderate-to-high yields and good-to-excellent enantioselectivities. The asymmetric arylation reaction can be applied in the formal synthesis of the clinical candidate compound (+)-AG-041R. Based on the results given by control experiments, three reaction models are proposed to illustrate the stereoselective-control outcomes.

Two novel -extended amine/carbonyl-based multi-resonance thermally activated delayed fluorescence (MR-TADF) emitters have been designed and synthesized. The two emitters are isomeric, comprised of nine fused rings and show green-yellow emission. Sym-DiDiKTa and Asym-DiDiKTa possess tert-butyl groups distributed in a symmetrical and asymmetrical fashion, respectively, which significantly impact the single-crystal packing structure. The two compounds possess similar singlet-triplet energy gaps, EST, of around 0.23 eV, narrowband emission characterized by a full width half maximum, FWHM, of 29 nm and a photoluminescence quantum yield, PL, of 70% and 53% for the symmetric and asymmetric counterparts, respectively, in toluene. Investigation in OLEDs demonstrated that the devices with Sym-DiDiKTa and Asym-DiDiKTa displayed electroluminescence maxima of 543 and 544 nm, and maximum external quantum efficiencies (EQEmax) of 9.8% and 10.5%, respectively. The maximum EQE was further improved to 19.9% by employing a hyperfluorescence strategy. We further present the first example of a neutral MR-TADF emitter incorporated in a LEC device where Sym-DiDiKTa acts as the emitter. The LEC shows a EL at 551 nm and FWHM of 60 nm with luminance of 300 cd/m2 and a fast turn-on time of less than 2 s to 100 cd/m2.

Desarrollamos el marco teórico que justifica la pertinencia de este enfoque en base a la naturaleza compleja y ecosistémica de la ciudad. También mostramos una guía práctica de recursos y herramientas básicas a utilizar para aplicar dichas metodologías a proyectos de carácter público: la mediación, los sistemas de compartición de datos, y los laboratorios urbanos o cívicos.
Enmarcada en el anterior marco teórico-práctico, proponemos una proto-metodología de diseño urbano ágil y lean start-up en 4 etapas que acompañamos de varios ejemplos o casos prácticos de proyectos de diseño de espacios y servicios públicos. Aunque cada uno de los ejemplos ilustran sólo de manera parcial el uso de los recursos, herramientas y proto-metodología propuestos, el conjunto muestra el camino para seguir investigando en pos de una metodología evolutiva aplicable al diseño urbano digital.
Una aproximación al conductor cautivo en el contexto de la ciudad de los 15 minutos. Astigarraga como caso de estudio
Authors: Gortazar-Balerdi Ander , Markusiewicz Jacek
Published: February 2023

Uno de los mayores retos de la ciudad contemporánea en relación con la transición energética es el de la movilidad sostenible, un tema atravesado, entre otros aspectos, por la dicotomía centro-periferia(s). Este artículo expone el caso de estudio de un proyecto llevado a cabo por los autores en su ejercicio profesional, a través del despacho RAZ: el análisis de los hábitos de movilidad relacionados con el trabajo asalariado en el municipio de Astigarraga, en Gipuzkoa, en el contexto de la redacción de su plan de movilidad urbana sostenible. El caso de estudio es una muestra de las dificultades inherentes a las dinámicas de movilidad metropolitanas contemporáneas, y ayuda a dibujar el perfil de conductor cautivo del automóvil privado. El análisis se llevó a cabo utilizando metodologías basadas en el análisis, la visualización y/o la simulación de datos, ayudando a ilustrar las oportunidades que nos brindan este tipo de metodologías también en el campo de la movilidad sostenible.
Cartas entre Alejandro Herrero y Félix Candela: amistad, arquitectura y técnicas constructivas
Authors: Rodrigues de Oliveira Silvana
Published: February 2023

Los arquitectos Alejandro Herrero Ayllón y Félix Candela Outeriño consolidan una gran amistad durante sus estudios en la Escuela Superior de Arquitectura de Madrid (promoción de 1935); comparten diferentes actividades, viajes de estudios, y redactan juntos apuntes de Resistencia de Materiales. Tras los avatares de la Guerra Civil Española, logran esquivar el supuesto control de la época prolongando esta amistad a través de una extensa relación epistolar. A partir de la metodología de estudio contrastado de fuentes primarias, este artículo ahonda en esos epistolarios de gran riqueza autobiográfica –custodiados en el Archivo Municipal de Huelva y en la Library Archive at Columbia University (New York)–, donde describen sus vidas, arquitecturas, técnicas constructivas, primeras conferencias y artículos, apoyándose mutuamente. Exiliado en México, Candela realiza sus primeras experiencias estructurales con las que logrará un gran reconocimiento internacional. Por otro lado, Herrero, en su retiro en Huelva, construye sus primeros proyectos de viviendas sociales y aldeas, integradas en el lugar y ajustadas a la difícil realidad española; más tarde, proyectará edificios relevantes que serán incluidos en el Docomomo Ibérico. Documentos todos que exponen contextos históricos que condicionan sus vidas y arquitecturas, aportando nuevas miradas.

Del modelado al modelo. Conversación con Laia Grau Balagueró
Authors: Martínez-Díez Pablo , Santamaría-Varas Mar , García-Pérez Sergio
Published: February 2023

Para cerrar esta reflexión temática en torno al uso de datos y metodologías que nos ayudan a describir, descubrir, predecir o simular lo urbano se entrevistó a Laia Grau Balagueró. Su visión, como gerente de urbanismo de la ciudad de Barcelona y con una trayectoria larga ligada a la administración pública y la libre actividad profesional como arquitecta, permite reconocer los retos y las oportunidades que la disciplina urbanística —y el planeamiento en particular—, tiene en relación con la transferencia de este conocimiento a las políticas públicas que definirán el modelo urbano de nuestras ciudades.

Published: February 2023

The concept of superquadratic functions of several variables with general kernels in the setting of time scales play a fundamental role in mathematical analysis. In this article, we derive some new results related to Hardy-type inequalities through Jensen inequality for multivariate superquadratic functions on time scales.
Using Stimulus Material to Explore How Supervisors and Candidates Clarify Expectations During the Research Supervision Process in England
Authors: Everitt Julia , Blackburn Carolyn
Published: February 2023

Aim/Purpose: This study examined the perceptions of doctoral supervisors and candidates around how expectations for doctoral supervision are clarified, and the strategies used.

Background: Clarifying expectations is recommended in supervisor and candidate handbooks, supervisor training and recognition programme. Formal strategies have been adopted as a blanket approach by some departments, faculties, or universities but little research explores supervisor and candidate perceptions of this practice or available strategies.

Methodology: Semi-structured interviews using stimulus material were held with nine supervisors and nine doctoral candidates from a university in England which adopts a team supervision model. Supervisor and candidate dyads were not used.

Contribution: This study can be used to consider the process of clarifying expectations. A smorgasbord or selection of strategies is presented, for practice.

Findings: Six supervisors were clarifying expectations at the beginning using an informal discussion, although some supervisors used multiple strategies. Candidates did not recall their expectations being clarified. Some supervisors and candidates believed that expectations did not need to be clarified and there were concerns about formal strategies. Team supervision had a positive and negative influence. Four candidates wanted expectations clarifying but the different starting points and power issues suggested that supervisors need to create the space for regular discussions as part of a working alliance.

Recommendations for Practitioners: The stimulus material or smorgasbord of strategies can encourage dialogue between supervisors and candidates to enable them to discuss and select appropriate strategies, from the full range available.

Recommendation for Researchers: Researchers might want to undertake their own studies using stimulus material. The smorgasbord could be used in practice and research undertaken to see how it could be further developed.

Impact on Society: Supervisors and candidates using the smorgasbord and the idea of the working alliance can assist to have ongoing conversations about expectations.

Future Research: Researchers could conduct studies in other universities to see if similar findings are discovered. Future research could be undertaken where institutions have adopted a formal approach.
Kitâbu’l-‘Ayn ve Kitâbu’l-Cîm’de n-f-s (ن ف س) kökü ve türevleri
Authors: ARSLAN İclal
Published: February 2023

Birçok disiplinde önemli bir yere sahip olan nefs (نَفْسٌ) kavramının zengin bir anlam yelpazesi vardır. Nefs kelimesinin sözlük anlamlarının klasik Arap dili sözlükleri perspektifinde etraflıca ortaya konulması, farklı disiplinlerdeki terim anlamlarının netleşmesine ve gereği gibi anlaşılmasına yarar sağlayacaktır. Bu açıdan nefs hakkında yapılacak yeni çalışmalara referans niteliği taşıyacak şekilde n-f-s (ن ف س) kökünün klasik sözlükler yardımıyla etimolojisinin yapılması büyük önem arz etmektedir. Bu çalışmada ilk sistematik kapsamlı sözlük kabul edilen Kitâbu’l-‘Ayn ile sözcüklerin, kökün ilk harfine göre alfabetik olarak sıralanmış olduğu Kitâbu’l-Cîm tercih edilmiştir. İlk aşamada bu sözlüklerdeki n-f-s kök malumatı etraflıca incelenmiştir. Sonrasında nefs kelimesi, çoğulları olan enfus (أَنْفُسٌ) ve nufûs (نُفُوسٌ) kelimeleriyle birlikte ele alınmıştır. Ayrıca nefs kelimesinin manalarında belirleyici olduğu düşünülen fiil vezinlerine değinilmiş, nefs ve nefes (نَفَسٌ) kelimeleri arasındaki ilintiye işaret edilerek sözlükler arasındaki anlam farklılıkları tespit edilmiştir. Böylelikle bu iki klasik sözlükten istifade edilerek “nefs” ve “nefes” kelimeleri için temel bir çerçeve ortaya konulmuştur. Çalışma sırasında bu iki klasik sözlükteki manalar; âyet, hadis-i şerif, Arap şiiri ve deyimsel ifadelerden oluşan şahidlerle desteklenmiştir. Anlamların tespitinde bilhassa kelimelerin Türkçeye aktarılmasında titizliğiyle meşhur olan el-Okyânûsu’l-Basît, diğer bir adıyla Kâmûs Tercümesi’nden istifade edilmiştir. Böylece el-Halîl b. Ahmed’in de dediği gibi birden fazla anlama sahip olan nefsin kavram alanını ortaya koyulmuştur. Yapılan çalışma sonunda görülmüştür ki, nefs kelimesinin sözlük anlamları birbirinden farklı olsa da, fiil formundaki anlamları alt alta sıralandığında, aralarında bazı ortak noktalar bulunmaktadır. Bu makalede amaç, n-f-s (ن ف س) kökünün sözcük anlamıyla ilgili bütün detayları ortaya koymaya çalışmak ve anlam sürecindeki gelişim seyrini ilk döneme ait zikredilen bu iki sözlük yardımıyla tespit edebilmektir.
Sanatsal ürünlerin farklı bir dile aktarımında dikkat edilecek hususlar: Wilhelm Busch’un klasiği Max ve Moritz
Authors: YALÇINKAYA AKÇİT Betül
Published: February 2023

Retorik bir yapının ve etkileyici bir dilin ön planda olduğu edebi metinlerin çevirisinde dikkat edilmesi gereken hususlar diğer metin türlerine göre daha fazladır. Zira söz konusu olan bir yazarın belirli ölçütler belirleyerek oluşturduğu bir metindir. Bu noktada yazarın hangi edebi türü seçtiği, hangi dönemde yazdığı, mesajını nasıl anlatmak istediği gibi belirleyici hususlar bulunmaktadır. Aynı zamanda dil kullanımı, seçilen kelimeler ve biçemsel özellikler de çeviri sürecini zorlaştıran noktalardır. Bundan dolayı çeviri sürecinin üç aşaması olan analiz, transfer ve sentez sürecinde yürütülen yöntem olgusal ve teknik metin çeviri süreçlerinden ayrılmaktadır. Edebi bir eserin çevirisi sadece kelime ve cümle yapısından yola çıkılarak yapılan bir transferden ibaret olmayıp birçok edebi unsurun bir araya geldiği bir süreçtir. Tüm bu sebeplerden dolayı bir edebi metni farklı bir dil ailesine mensup olan başka bir dile hiçbir kayba uğratmadan aktarmak mümkün değildir. Ancak eşdeğerlik konusuna dikkat edildiği takdirde kaynak metne çok yakın bir metin oluşturmak mümkündür. Eşdeğerlik konusunda ise özellikle W. Koller’in belirlediği kriterler üzerinde durmakta fayda vardır. Bahsi geçen eşdeğerlik kriterleri anlamsal, sözdizimsel, fonetik/fonolojik, morfolojik, pragmatik, stilistik, ortografik, iletişimsel ve işlevsel vb. boyuttadır. Bu çalışmada bir Alman klasiği olan Wilhelm Busch’un Max und Moritz adlı eseri ve Türkçe çevirisi Max ve Moritz incelenmiş ve söz konusu olan eşdeğerlik yönleriyle değerlendirilmiştir. Nesrin Çatak tarafından Türkçeye çevrilmiş olan eser, bir prolog ve epilog ile yedi epizottan oluşmaktadır. Çalışmada her bir başlık sayılan bakış açılarıyla incelenmiştir. Bu bağlamda kaynak metni belirleyen dilsel ve yapısal öğelerin hedef dile aktarımı tartışılmış ve bir çeviri eleştirisi yapılmıştır.
Çeviri ve Felsefe Meselesinin Derrida ve Zhuangzi Örneği Üzerinden Yeniden Yorumlanması
Authors: TARAKCIOĞLU Aslı Özlem , KOÇ YEL Elif Özge
Published: February 2023

Kaynak metnin analizinden hedef metnin oluşumuna giden yolda çeviri, felsefi söylemlerden faydalanır. Ancak çeviri ve felsefe ilişkisinin incelenmesi ve söz konusu ilişkinin “çeviri felsefesi” olarak adlandırılması oldukça yenidir. Çalışmada, öncelikle çeviri ve felsefe ilişkisinin gelişimi genel olarak resmedilmiştir. Esasen çeviri ve felsefe ilişkisinin sözcüklerin muğlaklığı noktasında birleştiği ekseriyetle gözlemlenmiştir. Bu nedenle, çevirinin ve felsefenin kesiştiği ve etkileştiği noktalardan birisi olan dile ve sözcüklere duyulan güvensizlik, çeviri felsefesi meselesinin sorunsallaştırılmasında yeniden yorumlanmıştır. Bu doğrultuda, Batı felsefesinden, çevirinin felsefi bir sorun olduğuna değinen Jacques Derrida’nın “pharmakon” örneği ele alınmıştır. Doğu felsefesinden ise Antik Çin felsefesi olan Daoizm’in (Taoizm-道) önde gelen filozoflarından Zhuangzi (莊子 MÖ 269- 386) tarafından ortaya atılan semantik güvensizlik üzerinden çıkarımlar yapılmıştır.
