Рассмотрены вопросы конструирования модульного биофильтра для очистки воздуха, загрязненного ароматическими углеводородами. Технология очистки воздуха методом биофильтрации была отработана ранее на пилотной установке. В результате анализа различных конструкций биофильтров и учитывая большую требуемую производительность по воздуху промышленной установки (70 000 м3/ч), для разработки был принят вариант с отдельными модульными биофильтрами в полной заводской готовности в виде утепленных контейнеров с размерами, позволяющими осуществлять их доставку на площадку монтажа обычным транспортом. Требуемая производительность установки набирается параллельным соединением необходимого количества единичных аппаратов. Для выявления возможных недостатков конструкции был изготовлен и испытан полномасштабный биофильтр. Выявленные негативные факторы устранены в проекте промышленного модульного биофильтра.

The issues of designing a modular biofilter for cleaning air polluted with aromatic hydrocarbons are considered. The technology of air cleaning using biofiltration was tested earlier at a pilot plant. Basing on the analysis of various biofilter designs and taking into account the high required air capacity of the industrial unit (70,000 m3/h), an option was adopted with prefabricated separate modular biofilters in the form of heat-insulated containers with dimensions providing for the delivery to the assembly platform by regular transport. The required capacity is achieved by parallel connection of the required number of individual apparatus. To identify possible design flaws, a full-scale biofilter was fabricated and tested. The identified negative factors were eliminated in the industrial modular biofilter project.

В соответствии с разрабатываемой на протяжении многих лет экологической программой по снижению негативного воздействия на водные ресурсы, металлургический завод запустил современный комплекс очистки промышленно-ливневых стоков сложного состава. Наибольшие трудности связаны с наличием в промышленно-ливневых сточных водах нефтепродуктов и тяжелых металлов, причем требования по удалению тяжелых металлов очень жесткие, прежде всего по содержанию меди, в очищенной воде оно не должно превышать 0,001 мг/дм3. Для оценки эффективности работы действующих очистных сооружений и принятия мер по их реконструкции специалистами металлургического завода были проведены научно-исследовательские изыскания по выбору оптимальной аппаратурно-технологической схемы очистки. После проведения пилотных испытаний были отвергнуты ранее предложенные схемы и разработана новая, которая должна удовлетворять всем требованиям. Созданный комплекс был запущен в постоянную эксплуатацию с достижением необходимых показателей очистки. Впервые в промышленном масштабе для очистки стоков от тяжелых металлов применена динамическая система умягчения (ДСУ) с колоннами диаметром 1800 мм.

In line with the environmental program being developed over many years to reduce the negative impact on water resources, the steelworks launched modern facilities for the treatment of industrial storm water of a complex composition. The greatest difficulties are associated with the presence of oil products and heavy metals in industrial storm water provided that the requirements for the removal of heavy metals are very stringent, primarily regarding the copper concentration, i.e. it should not exceed 0.001 mg/dm3 in the effluent. To estimate the efficiency of the existing treatment facilities and take measures for their upgrade, the experts of the steelworks carried out some research work to select the optimal equipment and technological treatment scheme. After the pilot tests, the previously proposed schemes were rejected and a new one was developed that should meet all the requirements. The newly designed facilities were put into constant operation with the required treatment efficiency achieved. For the first time a dynamic softening system (DSS) with columns 1800 mm in diameter was used on an industrial scale to remove heavy metals from wastewater.

Institutional gardens are special green spaces offering different functional and ecological benefits that can effectively support the well-being of urban residents. However, the role of institutional green spaces has changed throughout history, within various socio-political systems, and there have been many historical examples of the public use of institutional gardens. Today, institutional gardens are considered part of urban green infrastructure, but due to restricted public access – differing from completely private to semi-public use – we cannot state that they are essential open spaces for regular residential recreation. Continuously increasing urban density prompted new ideas in this field, which are worth analysing in detail. The article aims to give a general overview of the main historical examples of the public use of institutional green spaces, and the ideologies and the social or environmental factors affecting the functional change. After that, the authors – based on a literature review and professional experience – overview the current characteristics of the various types of institution gardens, then investigate the opportunities to open them for public use. Finally, the challenges of public use are systematically analysed. A case study analysis is presented on how educational green spaces could contribute to climate adaptation. The case study also aims to show that there is great potential in systematic thinking and reconsidering the role of institutional gardens in urban green infrastructure.
Egy budapesti turisztikai célpont, a Hármashatár-hegy felemelkedése és ambivalens fejlődése
Authors: Csemez Attila
Published: July 2024

A Budai-hegyek város-közeli vonulatainak turisztikai fejlesztésében jelentős különbségek voltak. Az eltérő kialakítás okai között az erdősült hegyekkel szomszédos város-részek jellege, a városi közlekedési hálózatok kiépítése,a domborzati adottságok, a turisztikai vonzáspontokat jelentő objektumok és az erdőállományok egyaránt szerepelnek. A Széchenyi-hegytől Hűvösvölgyig terjedő erdőkben a kirándulók már a 19. század végén megjelentek. A Mátyás-hegytől a Csúcs-hegyig terjedő hegyvonulat esetében az első turisztikai fejlesztési lépésekre csak az 1930-as évektől került sor. Az Árpád-pihenőt 1929-ben, a Hármashatár-hegyi turistaházat 1932-ben, a vitorlázó repülőtér pilótaotthonát és a hangárokat 1940-ben avatták.A II. világháborút követően a Hármashatár-hegy csúcsától északra fekvő vitorlázó-repülőtéri bázis honvédségi kezelésbe került, a déli oldalon pedig „zavaró-állomást” építettek. Lezárt katonai területek ölelésében a látogatók elevenem érezték jól magukat, amit a csúcsra vezető jelzett turistautak áthelyezése tovább fokozott. A Hármashatár-hegy csúcsán felállított antenna-erdő látványa sem voltvonzó a turisták számára. A taposási terhelésre érzékeny sziklagyepeket a H autóbusszal érkező tömegek a virágok szedésével, a piknikezéssel és a téli ródlizással jelentősen károsították. Az MHSZ gyakorló pálya kiépítésével 1973-ban a Hármashatár-hegy nyugati lankáján a növényzetet maradandóan károsították. A vegetációt a sárkányrepülősök, majd a siklóernyősök a starthelyeken tönkretették.A turisztikai szempontból mostoha viszonyokon a Pilisi Parkerdőgazdaság Zrt. jóvoltából a Hármashatár-hegyen folyamatosan sikerült javítani: 2016-ban átadták a Guckler Károly-kilátót, az egykori lezárt területen megnyitották a turistaházat, és a látogatók fogadására büfét nyitottak. A 495 m magas csúcs közelében az antennák látványa,az MHSZ pálya és a kerítések maradványai azonban még eltüntetésre várnak.
A víz megjelenése a XIX. századi tájképi kertekben a kataszteri térképek tükrében
Authors: Gyurasza Miklós , Sárospataki Máté
Published: July 2024

A mai Magyarország területére eső tájképi kertek egyértelműen leolvashatók a Habsburg Birodalom kataszteri térképlapjairól. Jóllehet, ezek a térképek egy kiragadott, szűk időintervallum állapotát rögzítik, mégis nagyon jó áttekintést nyújtanak a XIX. század második felében létezett kertekről. A víz tájképi kerti alkalmazásának jelentőségét alátámasztja, hogy közel 40%-a az akkor térképen rögzített parkoknak rendelkezett olyan jelentős vízarchitektúrával vagy természetes vízzel, amelyet érdemesnek tartottak ábrázolni. Kutatásunk eredményeképpen fény derült arra, hogy a magyarországi tájképi kertek egy adott időszakában milyen szerepet kapott a víz, milyen megjelenési formái voltak, és a parkok elrendezésében hol kaptak helyet, valamint a vizes elemet adó tájképi kertek milyen– vármegyék szerinti – eloszlásban jelentek meg.
Cesare Cases e la didattica della letteratura
Authors: Santarone Donatello
Published: July 2024

The essay examines a 1979 text by Cesare Cases in which the great Germanist argues, through ironic and pungent prose, against the technocratic approach to the analysis and teaching of literature. In this approach Cases sees the literary equivalent of the division of labour and the fragmentation of the subject, which are the foundation of the capitalist mode of production. From a theoretical methodological point of view, the essay underlines the importance that have for Cases Marxist historicism, the Hegelian-Marxian and Lukácsian category of “totality”, as an “attempt to reconnect the particular to the universal”, but always accompanied by a solid critical-philological foundation.
Forme della paralisi, forme dell’impegno: una lettura stilistica della Giornata d’uno scrutatore di Italo Calvino
Authors: Martinengo Margherita
Published: July 2024

The article presents a stylistic analysis of Italo Calvino’s La giornata d’uno scrutatore. It first explores the characteristics of the narrator (autobiographical matrix, relationship with the protagonist) and the function of parentheses, undoubtedly the most typical stylistic element of the work. The analysis highlights how La giornata d’uno scrutatore is supported by a binary and symmetrical principle, which affects both the content and the form of the narrative discourse; this principle is interpreted as a certification of the failure and of the impossibility of interpreting reality according to a dialectical (triadic) mechanism. The work finally follows the protagonist’s development. Amerigo Ormea initially appears to be stuck in a state of paralysis, but in the end, the only one among the protagonists of the Cronache degli anni Cinquanta, he becomes capable of defining a space, albeit limited, in which reason and ethically oriented action exist, opposing (aware of the limitations of his own action) the practice of electoral fraud at the “Cottolengo”.
«Qualcosa che non ho mai dimenticato»: Fortini lettore di Virgilio
Authors: Gigliotti Maria Teresa
Published: July 2024

The article analyses some Virgilian memories found in the poetic work of Franco Fortini, which act both at a para-textual level and at a deeper level, involving the structure of some compositions. The analysis uses the mechanisms of allusive art, which is based on the agreement between author and reader; it also highlights the vitality of Latin tradition in the poetry of Fortini. The references to famous Virgil’s verses, finally, can be found in the translation of John Milton’s Lycidas, included in the Ladro di ciliege e altre versioni di poesia (1982), an evidence of the intertextuality of the poem.
Kariera uczonego i tworzenie idei w warunkach fundamentalnych zmian strukturalnych. O Leonie Petrażyckim raz jeszcze
Authors: Dębska Hanna
Published: July 2024

This paper proposes an approach to scientific biography from the perspective of Pierre Bourdieu’s theoretical project. The choice of Leon Petrażycki (1867–1931), a philosopher and sociologist of law, who might be called an icon of the philosophy of law in Poland, results from the fact that his trajectory gives an insight into the interesting processes taking place in the scientific field, as well as in other social fields at the turn of the century up to the 1930s. Thus, L. Petrażycki is a ‘special case of what is possible’, a ‘product’ of the era. An era marked, on the one hand, by strong geopolitical divisions, corresponding to unequal flows of ideas between national scientific fields, on the other hand, characterized by high fluidity of the boundaries of social fields (science, journalism, politics), between which (up to a certain point) L. Petrażycki adroitly ‘moves’. Petrażycki’s trajectory is also interesting research-wise, as it reveals the influence of social structures on scientific positions occupied and positions takings in discourse. Furthermore, it shows how scientific failure is sublimated. Therefore, the article complements previous perspectives and is programmatic in that it can inspire similar endeavours in the future.

Navigating Lives: The Impact of Men’s Gulf Migration on “Left-Behind” Women in India’s Changing Landscape
Authors: Naz Shabista
Published: July 2024

Indians are the largest expatriate population in Western Asia, with a diaspora of around 8.5 million people, as a result of the movement of unskilled and semi-skilled work force from India, mainly to the Gulf region. This trend, which began in the 1970s following the discovery of oil, has had a transformative effect on the social fabric of both the migrant households and their families left behind in India. Several studies have examined male migration and role of family structures in changing the lives of “left-behind” women. This chapter aims to contribute to the existing literature by exploring the role of socio-economic change, particularly digital advancement and technology, in shaping the agency and autonomy of the women who were left behind. By incorporating the current aspects of technological advancement, a comprehensive understanding of the experiences of these left-behind women can be achieved. Drawing on existing studies, this chapter aims to critically analyse the effects of male migration on family dynamics and to underscore the significance of technology in reshaping the lives of left-behind women. Migration patterns from across India will be examined to provide a comprehensive view of the phenomenon.
Diaspora Bonds in the MENA Region: A Financial Insight
Authors: Nayak Nilanjana
Published: July 2024

A diaspora bond is a type of financial vehicle issued by a country to tap into the financial resources of its citizens living abroad, known as a diaspora. Patriotism is the principal motivation for the diaspora bond issue. These bonds are intended to encourage members of the diaspora to invest in their countries’ development projects, infrastructure, or other economic initiatives. This helps the country raise capital and develop while fostering a connection between the diaspora and their country of origin. Today, it is possible for immigrants to remain connected with their native countries and give back to their motherland. The emigration of skilled people is a loss for a country, but, on the other hand, skilled migration is an opportunity to receive remittances, trade, investment projects and new knowledge for a country. Some countries in the MENA region are pursuing government policies to develop links with their overseas citizens and encourage them to return or to use their knowledge and financial support for the development of their country.
Roots of Identity: Unpacking Memories in Indian and Pakistani Diasporas in the UAE
Authors: Mathur Sakshi , Mittal Shalini
Published: July 2024

This chapter presents an in-depth analysis of the very complicated interplay of memory and identity formation applicable to the specific population of the Indian and Pakistani diasporas in the United Arab Emirates (UAE). The UAE has one of the largest expatriate populations in the world, and Indians and Pakistanis hold the biggest diasporic communities amongst them. They are also one of the most culturally diverse expatriate communities in the UAE, having brought with them a rich melting pot of traditions, narratives, food, culture and memories that provide a structure to their sense of self in the foreign land. This chapter explores various theoretical frameworks in order to understand the factors that contribute to the formation of hyphenated identity in the diasporic community. The theories also help examine the role of individual and collective memory in shaping the self-perception of diasporic populations in a multicultural society like the UAE. A small section of the chapter also explores the historical context of the Indian and Pakistani diaspora in the UAE. Their shared historical memories still impact the integration process of both communities in the host country. Although this process of integration is fairly seamless, it comes with its own challenges.
The Price of Care: Sociality and Intermediary Networks of Kerala Migrant Care Workers in Israel
Authors: Koshy Sharon Susan
Published: July 2024

This study contextualises the intricate dynamics between intermediate networks and societal ties among migrant care workers from Kerala in Israel. The study sheds light on the larger concerns within the global care economy and emphasises the need for just changes to protect migrant workers’ rights and wellbeing by exposing a complex interaction of power, belonging and exploitation. In spite of regulations, illegal placement fees persist, due to a variety of complex reasons, including government complicity and lack of a bilateral agreement between India and Israel. International social networks are crucial in offering support, a sense of belonging, the circulation of information, and addressing mental health among migrant care workers. Additionally, these networks impart legitimacy to hiring procedures, thus shaping the power dynamics and obfuscating the distinction between ethical and exploitative behaviour. Malayali migrant care workers utilise community-building activities and weekend get-togethers as spaces to negotiate their cultural freedom and practise and recreate a sense of belonging in foreign lands.

Authors: Naha Alik
Published: July 2024

This abstract delves into the influential role played by the Indian diaspora in shaping India’s bilateral ties with the Middle East. As a critical demographic dispersed across various countries in the region, the Indian diaspora has emerged as a crucial bridge between India and Middle Eastern countries, fostering cultural, economic and political exchanges. The Indian diaspora’s historical presence in the Middle East has deep-rooted connections, dating back to centuries of trade, cultural exchange, and migration. Leveraging their cultural affinities and linguistic ties, the diaspora has facilitated seamless interactions between India and the Middle East, acting as agents of cultural diplomacy and mutual understanding. Economically, the Indian diaspora’s contributions have been significant, with their diverse skill sets and entrepreneurial spirit propelling growth in various sectors. Remittances from the diaspora play a vital role in India’s economy, bolstering trade and investment between India and Middle Eastern countries. Politically, the Indian diaspora’s active engagement in the political landscapes of their host countries and India has served to strengthen ties between governments. Lobbying efforts and advocacy for shared interests have contributed to enhanced diplomatic relations, facilitating cooperation on regional and global issues.

The article describes the results of thermodynamic modeling of the quasi-equilibrium state of water- ethanol mixtures, indicating that the associate composition determines the fire and explosion hazard. The binding role of water, which determines the ability of ethanol to evaporate from its aqueous solution, is also considered. The reasons for the absence of ethanol vapor in the gas phase have been clarified, which explains the non-flammability of low-concentrated water-ethanol solutions
MATHEMATICAL METHODS AND ALGORITHMS FOR ENCODING AND IDENTIFYING POLYMERIC PACKAGING MATERIALS TO PROTECT MULTI-ASSORTMENT PRODUCTS FROM COUNTERFEITING BASED ON LUMINOPHORES USING MOBILE DEVICES

To protect a wide range of products from counterfeit¬ing, two methods and algorithms have been proposed for encoding (formation of a reference electronic digital signature) and identification (assessing the authenticity) of packaging polymeric materials. El¬ements of protection are particles of luminophores that are randomly introduced into the polymeric ma¬terial during its production. Encoding and identi¬fication are carried out using mobile devices. The method for estimating the angles of triangles makes it possible to generate a digital signature based on processing an image (photograph) of a package with a unique arrangement of luminophore particles obtained from a mobile device camera, taking into account its angle of inclination relative to the package and image distortion. The digital signature of the package includes the values of the largest angles of a given number of triangles with the max¬imum area, built according to the brightest points (images of luminophore particles) in the image of the package. The method for estimating the decay time of a luminophore glow makes it possible to generate a digital signature based on processing a video recording of the glow obtained after exci¬tation of luminescence by light from a mobile device flashlight. The digital signature of the package in¬cludes the glow decay time values, unique for each type of luminophore and obtained from the decay curve of the glow intensity for three specified glow levels. At the encoding stage, the generated digital signature is saved as a reference for this package. At the identification stage, as a result of compar¬ing the generated digital signature of the package being checked with the reference digital signature, a conclusion is made about the authenticity or fal¬sification. Methods and algorithms are implemented in the form of a mobile software package, adjusted to various types of polymeric packaging and lumino¬phores, models of mobile devices, and requirements for identification accuracy. Testing of the software package using examples of coding and identification of rigid packaging films based on polyvinyl chloride using an iPhone smartphone has confirmed the opera¬bility of the algorithms. The developed methods and algorithms make it possible to reduce the number of counterfeit products (primarily pharmaceuticals), as well as reduce the costs of implementing product protection against counterfeiting due to the absence of the need to use additional expensive hardware

Published: July 2024

Tremor is the most common hyperkinesis. There is evidence that tremor often occurs in the event of a disturbance in the integrative activity of the central nervous system involving structures that relate to non-specific brain systems. The analysis of own and available in the literature clinical and experimental data on the effect on tremorogenesis of the vegetative system was carried out. Pathogenetically justified ways of correction were evaluated. In experimental studies, the participation of monoaminergic neurotransmitters in both tremorogenesis and autonomic dysfunctions has been revealed and confirmed. Our research and analysis of literary sources make it possible, in addition to diagnosis, to assess the balance of vegetative support, which improves adequate therapy.

Markers of inflammation in degenerative-dystrophic changes of the cervical spine
Authors: Khramtsov Denys , Vorokhta Yurii , Kalashnikov Valerii
Published: July 2024

The purpose of the study was to evaluate the dynamics of inflammatory markers in patients with degenerative-dystrophic diseases of the cervical spine accompanied by chronic pain syndrome. 94 patients with chronic cervicalgia aged from 20 to 70 years were examined. Women predominated among those examined (59 or 62.8 %). The average age of the patients was 57.6 ± 2.1 years. An analysis of the intensity of the pain syndrome in dynamics according to VAS, functional indicators according to the NPAD and NDI scales was carried out. In addition, the content of interleukin-6 and tumor necrosis factor in the blood, as well as the content of cortisol in saliva, were evaluated by the method of solid-phase enzyme immunoassay. All patients complained of long-term pain in the neck, which had the character of cervicocranialgia in 23 (24.5 %) patients, cervicobrachialgia in 31 (33.0 %) patients, cervicothoracic pain in 14 (14.9 %), isolated cervicalgia in 26 (14.9 %) patients. Pain intensity at the time of application was 6.8 ± 0.3 points. The score for NPAD was 65.5 ± 3.7 points, for NDI — 34.5 ± 1.1 points. All patients had pain in the neck, including 62 (66.0 %) — unilateral, and limitation of neck movements. In 37 (39.4 %) patients, the pain was mainly in the left half of the neck, in 25 (26.6 %) — in the right half. In 31 (33.0 %) neck pain was accompanied by pain in the shoulder girdle or upper limbs. Goniometric evaluation of the volume of neck movements revealed its decrease in all planes, more pronounced in the transverse plane. The cortisol content in the patients’ saliva was 6.5 ± 0.1 ng/ml, the IL-6 and TNF levels were 15.5 ± 0.8 and 8.6 pg/ ml, respectively. Correlation analysis showed a significant relationship between the degree of movement limitation, pain intensity and levels of pro-inflammatory cytokines and cortisol With chronic cervical pain, the cytokine cascade is activated, which leads to an increase in the levels of IL-6 and TNF to 15.5 ± 0.8 and 8.6 pg/ml, respectively, as well as cortisol to 6.5 ± 0,1 ng/ml. The degree of severity of clinical manifestations correlates with the content of cytokines and cortisol. The severity of the inflammatory reaction in chronic cervical pain should be taken into account when choosing therapy and rehabilitation measures.

The role of liquid phase microextraction in plant and animal food analysis
Authors: Kokosa John M.
Published: July 2024

Food samples require extensive sample preparations for instrumental analyses due to the complex matrices involved. Food safety regulatory agencies also require sample preparation procedures that are accurate, sensitive, robust, and, above all, fast, to handle the requirements for determining the safety of the massive amounts of foods and food products needed for human, pet and livestock consumption. There is also an inseparable interconnection between environmental, agricultural, forensic, cosmetic and industrial analytical chemistry involved in this requirement, and advances in analytical methodology are simultaneously applicable to all of these realms. As a response to these needs, the quick, easy, cheap, effective, rugged, and safe (QuEChERS) method was developed to provide multiclass analysis of agricultural products, and remains the basis for regulatory procedures for large scale analyses of food samples containing a wide variety of possible contaminants. However, since QuEChERS does not enhance analyte concentrations during sample preparation of these complex samples, the methodology also requires very expensive, very sensitive final analytical instrumentation, requiring highly trained personnel and continual maintenance. Smaller regulatory and field laboratories may also need sample preparation procedures for only a limited number of specific pesticides, metals, polycyclic aromatic hydrocarbons (PAHs) or other contaminants, requiring much less expensive and labor-intensive preparations and instrumentation. This is the role of liquid phase microextraction (LPME) in food sample preparation and analysis. LPME, individually or in combination with other sample preparation procedures, such as QuEChERS or traditional techniques such as solid phase extraction (SPE), can meet the requirements for sensitive and accurate analyses of specific analytes found in complex matrices, providing not only cleanup, but concentration of sample extracts, allowing the use of greener, less expensive and low maintenance final determination analytical instrumentation. Crucial review and application publications are tabulated to allow analysts easier access to appropriate publications to use this information for developing new or improved and greener validated methods for plant and animal food analyses.
Exploring the impact of immune response on tumor heterogeneity through mathematical modeling
Authors: Gautam Diksha , Kumar Sanjeev , Sharma Rashmi , Dixit Deepshikha
Published: July 2024

Aim: This article presents an investigation into various mathematical models for cell population growth, including tumor cells, and their dynamics.
Methods: We classify the models into five categories: exponential, logistic, time-tested, heterogeneous, and immunology. Mathematical modeling provides insights into the development of tumors over time and how their proliferation rate becomes more dangerous. To explore the impact of immune response on tumor heterogeneity, we develop a reaction-diffusion model of tumor growth that incorporates tumor-immune interactions and a mechanism for tumor mutation and clonal expansion. We use numerical simulations to investigate how variation in immune response affects tumor heterogeneity.
Results: Our findings show that a stronger immune response leads to greater homogeneity in the tumor population, which suggests that enhancing immune response could reduce tumor heterogeneity and improve treatment outcomes.
Conclusions: These results have important implications for the development of therapeutic strategies targeting the immune system to combat tumor heterogeneity.

Published: July 2024

This study focuses on researching the use of innovative technological teaching resources to improve the development of English speaking skills, recognizing that traditional methods have shown limitations in fully involving students in the learning process. This can result in sub-optimal levels of participation and achievement, indicating the importance of exploring and developing technological tools that address these challenges and encourage more effective and attractive learning. In this context, a mixed methodology was implemented that combined qualitative and quantitative approaches, allowing a thorough analysis of the situation. The results revealed a widespread interest in the use of technology for learning English, although differences were observed in the availability of technological resources among educational institutions. In addition, the need for student-centred pedagogy and the importance of adequate training for teachers in the effective use of technology were highlighted.
El Currículo Integrado: Perspectivas y Desafíos para su Implementación en las Escuelas Normales Superiores en Colombia
Authors: Jáuregui Mora Sandra Zulay
Published: July 2024

Este artículo de revisión bibliográfica examina las perspectivas y los desafíos en cuanto a la implementación del currículo integrado en las Escuelas Normales Superiores (ENS) de Colombia. Se identifican algunas características y particularidades de este enfoque curricular y su incidencia en la calidad del proceso formativo de maestros. La revisión destaca las metodologías recurrentes empleadas en los estudios y las ventajas de una educación integrada holística y contextualizada. Sin embargo, se reconocen ciertos retos significativos, como la resistencia al cambio respecto a las estructuras académicas tradicionales. Además, se señala la necesidad de investigaciones futuras debido a la ausencia de estudios específicos sobre el currículo integrado en las ENS en Colombia. Se proporcionan fundamentos teóricos y prácticos para la toma de decisiones en la construcción de políticas institucionales sobre currículo integrado y diseño de estrategias que fortalecen la formación de docentes en las ENS. Se concluye que los enfoques transversales e interdisciplinarios son importantes en la integración curricular pues estos permean el currículo en sus tres niveles de concreción: macro, meso y microcurrículo.
Actualización en Anemia de Fanconi: Bases Genéticas, Características Clínicas, Diagnóstico y Tratamiento
Authors: Ruiz Rodríguez Adriana , Quiroz Ruiz Diana
Published: July 2024

La anemia de Fanconi es un trastorno hereditario autosómico recesivo, poco frecuente. Se asocia con al menos 22 genes y produce fragilidad cromosómica, lo que implica defectos en la reparación del ADN, que a su vez conlleva a la aparición de tumores sólidos y hematológicos, principalmente leucemia mieloide aguda. El estándar de oro para el diagnóstico es la prueba de fragilidad cromosómica donde se observan anomalías después de ser expuesto a diepoxibutano o a la mitomicina C. El tratamiento comúnmente utilizado es el trasplante de médula ósea, sin embargo, este se asocia con la aparición de otros tumores, por lo que ahora se estudian terapias génicas.

Published: July 2024

Breast cancer accounts for approximately 16.6% of 396,914 cases of cancer and is one of the most fatal and common diseases among women. Treatment of breast cancer mostly has side effects, but the incidence of drug side effects does not always appear because the target drug does not selectively act on the target action. The aim of this study was to find a picture of post-chemotherapy treatment in breast cancer chemotherapy patients participating in the National Health Insurance at RSUD Yogyakarta. Observational method: Retrospective collection of data obtained from patients’ medical records. The subjects included patients with breast cancer at RSUD Yogyakarta who met the inclusion criteria for the primary diagnosis of breast cancer and received chemotherapy medication during the period of 2020. The univariate analysis showed the distribution of frequency and percentage of respondent characteristics, including age, gender, number of patients, single and combination chemotherapy drugs, generic and commercial drugs, and single or combination post-chemotherapy medications. The results were obtained from 72 patients who underwent 4 periods of chemotherapy. The most frequently used chemotherapy regimens for each period were the period 1 combination of Brexel, Epirubicin, Carboplatin. Period 2 combination of the Brexel and Zometa regimes. Periode 3 combination brexel, epirubicine, and carboplatin. The most widely used combination of post-chemotherapy drugs in periods 1-4 was the combination of Ranitidine and Ondansetron.

Pembentukan hukum merupakan fungsi ketatanegaraan yang dilakukan oleh badan eksekutif, legislatif, dan yudikatif untuk membentuk hukum, baik yang tertulis maupun tidak tertulis. Dengan menggunakan metode analisis, eksplorasi, penjelasan, dan pemaparan. Dalam konteks ini, penting untuk merancang suatu skenario politik perundang-undangan nasional yang berorientasi pada pemahaman konsep sistem hukum nasional. Tujuannya adalah untuk mewujudkan negara hukum yang adil, demokratis, serta berintikan keadilan dan kebenaran yang mengabdi kepada kepentingan rakyat dan bangsa. Selain itu, pembentukan hukum juga dipengaruhi oleh konfigurasi politik yang melatarbelakanginya, di mana hukum berperan sebagai sarana kekuasaan politik dominan. Dengan demikian, pemahaman tentang politik hukum dan hubungannya dengan pembentukan hukum sangat penting dalam konteks pembangunan hukum yang responsif dan berkeadilan.
