UNVEILING CONFORMITY AND DIFFERENTIATION THROUGH DERRIDA'S "DIFFERANCE"
Authors: Vasanathan R
Published: February 2024

This essay investigates the complex area of linguistic interpretation through the lens of Jacques Derrida's seminal concept of "difference." It begins a journey from the pursuit of static unity to the embrace of static difference, in the process illustrating the paradoxical space between conformity and personal choice. Language is dynamic, subject to contextual changes and influenced by historical contingencies. In the pursuit of fixed unity, a resistance mechanism is triggered, leading to a proliferation of differences instead of conforming to predetermined axes. This resistance mechanism embodied by "difference" paradoxically intensifies the inherent complexity and ambiguity of language. This forces individuals to oscillate between their initial intentions and unintended consequences, often ending up with a unique fit within their chosen interpretive framework. "Difference" challenges traditional notions of fixed similarity and illuminates the nuanced interplay between conformity and difference in the complex web of linguistic coding. Ultimately, this study unravels the problem of interpretation and reveals that harmony can emerge beyond the boundaries of traditional unity shaped by individual motives and interpretive choices.

Published: February 2024

Jeoit belirleme çalışmalarında 1 santimetre doğruluklu jeoit modeli oluşturmak ana hedeftir. Bu hedefin en hızlı ve en pratik şekilde çözülmesi bazı mühendislik problemlerinin çözülmesini kolaylaştırmaktadır. Bu nedenle jeoit belirmek için kullanılan yöntemler gün geçtikçe geliştirilmektedir. Stokes-Helmert yaklaşımı klasik jeoit modelleme seçeneklerinden biridir. Sınır değer probleminin çözümünde topoğrafya dikkatli bir şekilde ele alınmaz ise istenen hedefe ulaşmaya engeldir. Stokes-Helmert yaklaşımının son aşamasında PITE’nin (Birincil Dolaylı Topoğrafik Etki) hesabıyla kesin jeoit yüksekliği elde edilmektedir. Yoğunluk değişimi, PITE’nin hesabında ve dolayısıyla, jeoit yüksekliklerinde anlamlı farklılığa neden olur. Bu farkı görmek için bir sayısal yükseklik modeli ve kabuk yoğunluğu modelinden yararlanmak yeterlidir. Topoğrafyayı ilgilendiren yerbilimleri çalışmalarında yoğunluk değeri genelde ortalama 2.67 gr/cm³ alınır. Ancak bu değer bazı bölgelerde %20’lere yaklaşan farklılık gösterir. Yoğunluk değişimindeki böyle bir oran PITE hesabından bulunan değerleri desimetre mertebesinde etkiler. Bu çalışmada yoğunluk değişiminin PITE üzerindeki etkisi incelenecektir. Bu sayede ülkemizde santimetre doğruluklu jeoit belirleme çalışmalarına önemli bir katkı sağlanacaktır. PITE değerleri hesap noktasının yüksekliğine ve yoğunluğuna bağlıdır. Sayısal uygulama sonucunda değişken yoğunluklu PITE değerleri -43 cm ile -1 cm arasında değişirken, sabit yoğunluk kullanıldığında bu değerler -39 cm ile -10 cm arasındadır

Direito do mercado financeiro e de crédito
Authors: Pimenta Eduardo Goulart
Published: February 2024

O estudo do Direito Empresarial sempre passou, desde os tempos em que a disciplina era denominada Direito Comercial, pelo estudo dos Títulos de Crédito.

Baseada na apresentação e análise das normas sobre a Letra de Câmbio, Nota Promissória, Cheque e Duplicatas, a matéria tornou-se, com o tempo, objeto de crescentes críticas, ao fundamento de que se desconectava da realidade das transações envolvendo o uso do crédito.

É, de fato, inegável que os quatro modelos fundamentais sobre os quais a disciplina se apoiava caíram, em maior ou menor proporção, em desuso, o qual se aprofundou a partir da massificação das transações pela internet. Apesar disso, ainda é indispensável, para a boa compreensão da regulação jurídica das relações creditícias, o conhecimento de institutos como endosso, aval e protesto, os quais têm, ainda hoje, grande utilidade.

Conciliar a necessária abordagem destes temas, ainda caros ao estudo da disciplina, com questões decorrentes, em sua maioria, da já aludida massificação das transações pela internet, foi o ambicioso objetivo deste trabalho.

Desta forma, o texto procura apresentar e analisar institutos ligados à forma tradicional do tema e, em sequência, conciliá-los com questões atuais, como a disseminação de arranjos de pagamento, smart contracts, data science e financiamento participativo, entre outros.

Neste caminho, a abordagem se divide em dois grandes eixos, sendo um deles dedicado ao estudo do fornecimento de crédito com patrimônio próprio e o outro referente ao fornecimento de crédito realizado a partir de dinheiro captado, pelo fornecedor, no mercado.

‘Baekjeong’ Appeared in the Annals of the Joseon Dynasty: Focused on the Origin, Identity, and Assimilation Process
Authors:   The Association Of Korean Cultural And Historical Geographers, Lee Jeon , Lee Howook
Published: February 2024

Before the start of the Joseon Dynasty, nomads from various ethnicities entered the Korean Peninsula from the north. In the early Joseon Dynasty, the scattered inhabitants in the country, who were either the northern nomads or their descendants, began to be called Baekjeong. During the Joseon Dynasty, Baekjeong were primarily engaged in animal slaughter, leather manufacturing, crafting daily necessities from willow trees, and traveling to different villages to provide entertainment. To facilitate the integration of the Baekjeong with the natives, officials of the early Joseon Dynasty implemented several civilization policies, including allocating land for farming, registering them in the family register to encourage settlement, etc. Despite these efforts, Baekjeong were originally commoners but faced discrimination due to their status as outsiders in the early Joseon Dynasty, as they could not easily abandon their nomadic lifestyle. However, following the Imjinwaeran and the Byeongjahoran, the term Baekjeong underwent a change in meaning, evolving into a discriminatory label for individuals who no longer belonged to nomadic descent, but only worked in menial occupations such as slaughter and organic manufacturing, in a situation where they were completely assimilated with the native population. Baekjeong had the identity of northern nomads in the early Joseon Dynasty, but they played a significant role in shaping present-day Korean people through their assimilation with the native inhabitants of the Korean Peninsula.

Published: February 2024

The brand is the manufacturer's public persona, a barometer of the company's public standing, and a watershed moment in the company's overall business strategy. There's no getting around the fact that a product's brand serves as its identity; after all, it's what sets one firm apart from another. The protection of registered marks, however, is sometimes the source of intricate legal challenges that obscure the mark's true significance. The purpose of this research is to evaluate and analyze the legal protection of registered trademarks and to determine the reason of the termination of its protection using a normative juridical approach. The research uncovered a number of potential triggers for a brand's registration to be revoked, such as the end of the brand's validity period, a request for revocation by the brand's owner, ministerial initiative based on the recommendation of the brand appeal Commission, or a lawsuit filed by a third party. Once the trademark is registered, it is protected for a certain length of time that may be extended. Legal action, criminal prosecution, and administrative measures like trademark cancellation or registration rejection all serve as deterrents. Defending corporate identities through trademarks is crucial in today's period of intense global competition. This study delves deeply into the value of brands to manufacturers and the legal hurdles that must be overcome to ensure a brand's long-term viability in a competitive market. With this knowledge in hand, company stakeholders may take the necessary initiatives to establish a brand that will endure. Protecting your name and your ideas are essential.

This work is very strategic considering that the route is one of the accesses to national vital objects (obvitnas) of the Samarinda - Balikpapan Toll Road. In addition to providing comfort for road users, the path will be a storefront for Samarinda City. This path will be an access in and out of and to the Palaran Toll Gate. Previously, the two-lane road section was only used for one lane on the right side of the Palaran Main Stadium. The lane was partially destroyed, scrubbed and only became a parking office for trucks and containers. But considering that this road is a provincial road, the existing road conditions are considered unable to accommodate the capacity of vehicles going through this route. So it is necessary to rebuild and improve roads on the East Kalimantan Main Stadium Road Section at Sta. 1+644 – Sta. 3+405 to facilitate economic traffic and also avoid traffic accidents in the area. The methods used to obtain data are direct observation methods of activities that occur in the field and secondary data collection in the form of test result data, and work plan drawings. The purpose of writing this article is to find out the stages of implementation and supervision of cement concrete pavement road work, especially in ironing work.

В статье описана попытка идентификации пептидного состава экстракта простаты крупного рогатого скота, произведённого по технологии водно-уксусной экстракции с последующей тангенциальной ультрафильтрацией. Обнаружены белково-пептидные компоненты с известной функциональной активностью. Среди найденных фрагментов регуляторных белков был отобран, синтезирован и протестирован в трех биологических моделях новый, не описанный ранее пептид, являющийся фрагментом бычьего хемокина МСР-1. Показана способность пептида in vitro подавлять миграцию моноцитарных клеток и агрегацию тромбоцитов. По результатам проведенного анализа найденный пептидный фрагмент оценен как перспективный для создания синтетического аналога экстракта простаты, а также для терапии заболеваний аутоиммунной и псевдоаллергенной природы.

Персистенция вируса папилломы человека приводит к нарушению процессов пролиферации и дифференцировки многослойного плоского эпителия шейки матки с развитием цервикальных интраэпителиальных неоплазий и рака шейки матки. В процессе неопластической трансформации принимают участие гормональные факторы. Целью данного исследования являлась оценка влияния глицирризиновой кислоты на жизнеспособность клеток аденокарциномы шейки матки линии HeLa при разных концентрациях половых стероидных гормонов. Концентрация полумаксимального ингибирования жизнеспособности (IC50) глицирризиновой кислоты в отношении клеток аденокарциномы шейки матки линии HeLa составила 72,2 мкМ, в присутствии тестостерона (10 и 1 мкМ) IC50 глицирризиновой кислоты увеличилась на 13,4 и 17 %, в присутствии эстрадиола (10 и 1 мкМ) — уменьшилась на 1,8 и 11,8 %, в присутствии прогестерона (10 и 1 мкМ) — увеличилась на 8,7 и 8,6 %, соответственно. Таким образом, тестостерон и прогестерон в концентрациях 10 и 1 мкМ ослабляют, а эстрадиол в низкой концентрации (1 мкМ) усиливают антипролиферативное действие глицирризиновой кислоты.

Выполнены исследования по изучению изменений количественного содержания и специфической активности фермента гиалуронидазы после обработки ультразвуком растворов бовгиалуронидазы азоксимера. Объектами исследования являлись растворы готовой лекарственной формы бовгиалуронидазы азоксимера (препарат Лонгидаза® лиофилизат для приготовления раствора для инъекций, 3000 МЕ) и фармацевтической субстанции бовгиалуронидазы азоксимера (субстанция-лиофилизат Лонгидаза®). Цель работы — определение влияния ультразвука (УЗ) на стабильность бовгиалуронидазы азоксимера, определяемую на основании измерений количественного содержания и ферментативной активности вещества в растворе. Установлено, что ультразвук при интенсивности излучения 61,4 Вт/л при обработке в УЗ-излучателе не оказывает существенного влияния на количественное содержание фармацевтической субстанции бовгиалуронидазы азоксимера в растворе, при этом снижение ферментативной активности действующего вещества в растворе препарата Лонгидаза® после 20 и 30 мин УЗ-обработки было статистически значимым. В то же время после небулизации раствора бовгиалуронидазы азоксимера в меш-небулайзерах различных производителей результаты определения ферментативной активности действующего вещества, полученные биохимическим методом, значительно отличались (остаточная активность от 99,70 до 59,27 %) в зависимости от конструктивных особенностей небулайзеров и времени небулизации. Время небулизации менее 15 мин в наименьшей степени было сопряжено с риском значительной потери стабильности бовгиалуронидазы азоксимера.

Analysis of mythological structures in Valerii Shevchuk’s ballad novel “House on the Hill” (Dim na hori) in high school
Authors: Sydorenko Yuliia
Published: February 2024

The issue of studying Valerii Shevchuk’s ballad novel «House on the Hill» (Dim na hori) in secondary schools is addressed through an analysis of explicit mythological structures. The relevance of this study is justified by the author’s use of syncretic mythological imagery at various levels of literary material. This aspect needs to be taken into consideration when studying the ballad novel by students in the 11th grade. Methods and approaches for analysing explicitly expressed mythological structures are proposed. Various approaches for studying the functional role of mythological imagery in comprehending the narrative content, temporal and spatial organisation, imagery system, symbolism, ideological content, themes, issues, genre, and stylistic nature of Valerii Shevchuk’s ballad novel «House on the Hill» (Dim na hori) are outlined. The methodology for narrative-mythological analysis of the work involves the identification and in-depth examination of significant episodes with mythological imagery. This includes extracting mythical inserts, legends, fragments of mythic texts, and episodes featuring key mythologemes or symbols of mythological content. The methodology also includes establishing connections between these elements, determining their semantic significance, and analysing their artistic roles. The step-by-step approach of this work is aimed at developing students’ skills in textual analysis of the literary work. The specifics of applying narrative-mythological analysis to Valerii Shevchuk's ballad novel «House on the Hill» (Dim na hori) are detailed in a specially designed lesson for 11th-grade students. The educational activities of the students focus on analysing the key mythological structure (legends about the house on the hill), the biblical parable of the prodigal son, mythologemes-symbols (house, hill, road, woman), and establishing their connections with other layers of the work. This allows for a comprehensive understanding of the literary material and helps improve skills in critical reading and analytical-synthetic work with literary texts. Keywords: literature lessons, teaching methodology of literature, mythological imagery, explicit mythological structures, narrative-mythological analysis.
