Authors: Trishna Rajendra Gothe  , Prof. W. A Gavhane
Published: August 2024

A static synchronous compensator (STATCOM) is reviewed along with Multilevel inverter in this study, which uses another secluded design with standard three-stage voltage source inverters to staggered activity. The inverters are linked to a transformer with three free DC joins and an open-end winding plan. The inverters in this development will be connected in a fountain design. Besides multi-facet working, the framework is recognized by low important impeding voltages for switch evaluations, as the proposed STATCOM might apply twofold the DC capacitor voltage to the transformer windings. The proposed geography’s control framework advancement is likewise given. A few demonstrating and reasonable tests will be performed to assess the activity of the recommended geography and the presentation of the laid out control framework. Voltage regulation and maximum power transmission can be achieved via reactive power compensation in a power system. The reason for this audit article is to zero in on different elements of STATCOM, for example, various arrangements, regulation methods, the idea of new decreased switch count geographies, applications incorporating connection point with environmentally friendly power, engine drives, and Realities regulator

Assessing Human Impact on Air Quality with Bayesian Networks and IDW Interpolation
Authors: Durairaj Hema , Dharshini L Priya
Published: August 2024

As the explosion of the human population happens globally, meeting the demands for livelihood should also involve considerations for sustainability. Though there are several causes of global warming, air pollution makes a tremendous contribution to it. The Air Quality Index (AQI) measures how clean or polluted the air is in specific areas based on six major pollutants such as sulphur dioxide (SO2), nitrogen dioxide (NO2), ground-level ozone (O3), carbon monoxide (CO), and particulate matter (PM2.5 and PM10). There are six levels in the AQI, as "good," "satisfactory," "moderate," "poor," and "severe," that validate the score between 0-500. The implicit factor that affects the AQI is human movement within the environment. This research work involves real-time datasets collected from the TNPCB (Tamil Nadu Pollution Control Board) regarding Madurai’s AQI at three stations collected for the year 2021(during COVID-19 period). The Bayesian network exhibits the causal relationship between human movement and the Air Quality Index through probabilistic modelling. An IDW Interpolation chart is also visualized to conceptualize the human intervention (NIL, Partial and Complete) for the AQI value obtained in 3 stations.

Linkages with practice for higher-education curriculum innovation
Authors: Nampala Paul , Kalule Stephen W. , Mshenga Patience M. , Okello Daniel M. , Egeru Anthony , Ekwamu Adipala
Published: August 2024

This article is inspired by the debate on curriculum innovation for graduate training, emerging out of linkages between universities and agribusiness development actors, targeting entrepreneurial action and employability of graduates. Experiences from implementation of a three-year joint project are enriched by a desk review, stakeholder feedback and interpretative analysis of process documents during the development of the regional graduate curriculum on Agri-Enterprise Development for Egerton and Gulu Universities in Kenya and Uganda, respectively. The graduate curriculum at the two universities in East Africa integrated the approaches of roundtable engagement and research as well as value chain cluster mapping and development through interactive sharing with agribusiness development facilitators. Simultaneously, the two implementing universities showcased the feasibility of integrating community engagement and entrepreneurial skills into a new curriculum. They achieved this by adopting two training approaches from their previous, more limited curriculum, which lacked student entrepreneurial experiential learning. The outcome from the first cohort of students in the innovative programs demonstrates significant institutional change in teaching and learning approaches. These changes prioritize a blend of action research and theoretical exposure. At the university-wide level, a student-centered teaching and learning approach has been established, facilitated by models like Student Farm Attachment, Student Enterprise Scheme, and Student Community Engagement. Additionally, university-based research teams have honed their skills in community action research, leading to the identification of relevant challenges and plausible solutions. Furthermore, students’ skills sets have increasingly enhanced employability.

Strengthening linkages between universities and community development actors can enhance curriculum orientation toward problem-solving and entrepreneurial capacity building for young graduates. Purposeful engagement with communities by university faculty and students serves as a complementary extension approach and advisory service. Implementing an innovative curriculum has the potential to boost research uptake and foster innovation. This article demonstrates how university- industrial actors’ collaboration can be exploited for curriculum (re)design, review and up-dating for (a) enhanced relevance of universities to community needs and employability of graduates; and (b) improvements in the research uptake pathways that facilitate research-into-use for desired impacts at community level.
Plication or resection combined with antagonist recession in horizontal strabismus
Authors: AlSahaf Esra , AlShamlan Fatemah T
Published: August 2024

Background: Strengthening of extraocular muscles is a conventional procedure in the management of strabismus. Plication may be an alternative strengthening technique, and is less invasive than resection. This study compared plication and resection, each combined with antagonist muscle recession, in terms of success rates and changes in ocular deviation in the management of horizontal strabismus.
Methods: This retrospective study recruited individuals with horizontal strabismus who underwent plication (group I) or resection (group II) coupled with antagonist muscle recession. All participants underwent a detailed baseline eye and ocular motility evaluation. Demographic and clinical data were collected, including age, sex, type of preoperative strabismus (exotropia or esotropia), baseline visual acuity, mean follow-up duration, laterality of operated eye, surgical doses of correction (resection, plication, or recession) in millimeters, preoperative strabismus magnitude in prism diopters (PD), and postoperative strabismus magnitude in PD. Successful postoperative deviation was defined as less than or equal to 10 PD. At final follow-up, the success rates and degrees of change in angle of deviation were recorded.
Results: Forty-four patients were enrolled: 19 patients in group I (plication) and 25 patients in group II (resection). The groups had comparable ages, sex ratios, types of strabismus, and preoperative and postoperative angles of deviation (all P > 0.05). Despite comparable success rates between groups (73.7% in group I versus 64.0% in group II, P > 0.05), the difference (9.7%) was marginally close to the predefined clinically meaningful difference of 10%. In the esotropia subgroup, despite comparable alignment between the plication and resection groups (P > 0.05), the difference was clinically meaningful (17.3%), and both groups had higher success rates in the esotropia subtype than in the exotropia subtype. The rate of over- or undercorrection was not statistically or clinically different in the total and in each subtype of strabismus (all P > 0.05). Success rates for unilateral and bilateral cases were similar between groups (both P > 0.05). Changes in angle of deviation were similar for individuals with esotropia and exotropia between groups (both P > 0.05).
Conclusions: In esotropic and exotropic strabismus, plication and resection procedures combined with antagonist recession were similarly effective. However, further randomized, large-scale, longitudinal studies with clinical and subjective evaluations could provide practical evidence on the suitability of the plication procedure in managing various types of strabismus.

Authors: Babu KL Girish , Gururaj Hebbar Kavyashree
Published: August 2024

Aim: This study aimed determine the influence of the type of root canal instrumentation file systems and obturating materials on the success of pulpectomized teeth. Methods: Two hundred eighty-eight primary molars from children aged 4–7 years were selected and divided into three groups of 96 teeth each. In the first, second, and third groups, root canal instrumentation was performed using Kedo-SG pediatric rotary files (KS), HERO Shaper rotary files (HS), and manual Ni-Ti K-files (MF), respectively. Following instrumentation, these three groups were subdivided into three subgroups of 32 teeth each and obturated using zinc oxide eugenol, Endoflas®, and DiaPex Plus®. The quality of the root filling was assessed immediately and evaluated clinically and radiographically over two years. The Chi-Square Test was used to analyze the data, with the level of significance set at P<0.05. Results: The quality of obturation was superior in root canals instrumented with rotary file systems compared to manual files. No significant difference in obturation quality was noted among the obturating materials used. The clinical success rate after two years was 100%. Radiologically, success rates were 97% for Kedo-SG, 94% for HERO Shaper, and 89% for manual file systems. For obturating materials, the success rates were 90%, 96%, and 94% for zinc oxide eugenol, Endoflas®, and DiaPex Plus®, respectively. Conclusions: The success of pulpectomized teeth was not significantly influenced by the type of root canal instrumentation file systems or the choice of obturating materials.
Pediatric dentistry approach in a child with Aicardi-Goutières Syndrome type 2: A case report and literature review
Authors: Sözüöz Melis Arda , Aydın Varol Ezgi , Aksoy Merve
Published: August 2024

Aicardi-Goutières Syndrome is a rare autosomal recessive disorder characterized by a triad of partial or complete agenesis of the corpus callosum, infantile spasms, and chorioretinal lacunae. The condition predominantly affects females, as males often do not survive the embryonic period. Intellectual disability associated with the syndrome ranges from mild to moderate. There is limited information in the literature regarding the oral manifestations of this syndrome. This case report aims to provide insights into the development of primary dentition in patients with Aicardi-Goutières Syndrome and to raise awareness about the oral and dental health needs of these rare pediatric patients, particularly during early childhood. In this case report, it was observed that the primary teeth of a 2-year-5-month-old patient had not yet erupted. Notably, even at 3 years and 1 month old, the patient’s primary dentition remained incomplete despite continued monitoring during follow-up examinations. These patients often have limited ability to cooperate with dental treatments due to their intellectual disability, which complicates the process. Furthermore, due to the respiratory risks associated with the syndrome, dental treatments under general anesthesia are generally not preferred. In this context, maintaining the oral health of these patients and implementing preventive strategies, including topical fluoridation, along with appropriate oral hygiene instructions and dietary modifications, are crucial in managing patients with Aicardi-Goutières Syndrome. Pediatric dentists are responsible for educating families on these matters, and caregivers play a vital role in maintaining the oral health of these patients by collaborating closely with dental specialists.
Conservative aesthetic management of dental fluorosis using microabrasion with two different acidic compounds in pediatric patients: A report of two cases
Authors: Ahmad Nehal , Yunus Khan Saima , Sanjay Sharma Divya , Kumar Jindal Mahendra , Azam Imam , Atif Mohammad
Published: August 2024

Dental fluorosis is a subsurface hypomineralization condition, characterized by yellow to dark brown stains, with or without enamel porosity and pitting. Due to aesthetic concerns, children with discolored anterior teeth often experience negative impacts on their psychological, emotional, and social development. Treatment options include porcelain laminates or veneers, direct resin restorations, and crowns. However, these methods are invasive and require significant enamel reduction, making them unsuitable for children due to their enlarged pulp chambers. Microabrasion is the least invasive and safest treatment for children with fluorosis. This technique involves using a combination of 37% phosphoric acid gel with extra fine grain pumice, 18% hydrochloric acid in pumice, or 6.6% and 10% hydrochloric acid with silica carbide particles. The mixture is applied with a slowly rotating rubber cup to the areas of discoloration or white opacities. An additional benefit of microabrasion is that it leaves the enamel surface highly polished, reducing the growth of cariogenic bacteria and increasing resistance to demineralization. This case report describes two instances of dental fluorosis treated with microabrasion using different acidic compounds in two pediatric patients, resulting in clinically acceptable and aesthetically pleasing outcomes.

Relations between cyclones and ozone changes in the Arctic using data from satellite instruments and the MOSAiC ship campaign
Authors: Monsees Falco , Rozanov Alexei , Burrows John P. , Weber Mark , Rinke Annette , Jaiser Ralf , von der Gathen Peter
Published: August 2024

Abstract. Large-scale meteorological events (e.g. cyclones), referred to as synoptic events, strongly influence weather predictability but still cannot be fully characterised in the Arctic region because of the sparse coverage of measurements. Due to the fact that atmospheric dynamics in the lower stratosphere and troposphere influence the ozone field, one approach to analyse these events further is the use of space-borne measurements of ozone vertical distributions and total columns in addition to conventional parameters such as pressure or wind speed. In this study we investigate the link between cyclones and changes in stratospheric ozone by using a combination of unique measurements during the Multidisciplinary drifting Observatory for the Study of Arctic Climate (MOSAiC) ship expedition, ozone profile and total column observations by satellite instruments (OMPS-LP, TROPOMI), and ERA5 reanalysis data. The final goal of the study is to assess whether the satellite ozone data can be used to obtain information about cyclones and provide herewith an additional value in the assimilation by numerical weather prediction models. Three special cases during the MOSAiC expedition were selected and classified for the analysis. They are one “normal” cyclone, where a low surface pressure coincides with a minimum in tropopause height, and two “untypical” cyclones, where this is not observed. The influence of cyclone events on ozone in the upper-troposphere lower-stratosphere (UTLS) region was investigated, using the fact that both are correlated with tropopause height changes. The negative correlation between tropopause height from ERA5 and ozone columns was investigated in the Arctic region for the 3-month period from June to August 2020. This was done using total ozone columns and sub-columns from TROPOMI, OMPS-LP, and MOSAiC ozonesonde data. The greatest influence of tropopause height changes on ozone contour levels occurs at an altitude between 10 and 20 km. Moreover, the lowering of the 250 ppb ozonopause (at about 11 km altitude) below 9 km was used to detect cyclones using OMPS-LP ozone observations. The potential of this approach was demonstrated in two case studies where the boundaries of cyclones could be determined using ozone observations. The results of this study can help improve our understanding of the relationship between cyclones, tropopause height, and ozone in the Arctic and demonstrate the usability of satellite ozone data in addition to the conventional parameters for investigating cyclones in the Arctic.
Solar cycle signatures in lightning activity

Published: August 2024

Abstract. The cross-correlation between annual lightning frequency and solar activity and the heliospheric magnetic field (HMF) is examined on a global scale using corrected data from the World Wide Lightning Location Network (WWLLN) for the period 2009 to 2022. Relatively large regions with significant cross-correlation coefficients (p<0.05) between the yearly lightning rates and sunspot number (SSN) are found in eastern Africa, part of South America overlapping with the South Atlantic Anomaly, and the Indian Ocean and west coast of Australia. The main region that shows a significant correlation between lightning activity and the By component of the HMF and the magnetopause reconnection Kan–Lee electric field matches the South Atlantic Anomaly quite well. Also shown are areas that show a significant cross-correlation of lightning activity with the El Niño–Southern Oscillation index. Similar areas of significant cross-correlation are obtained if simulated thunder days are used instead of lightning counts. Possible mechanisms leading to the observed correlations and limitations of the current study are discussed. The findings of the present study do not support previous works indicating that cosmic ray intensity is in phase with the global occurrence of lightning, but they do not rule out the role of cosmic rays in lightning ignition in developed thunderclouds and the role of energetic particles precipitating from the magnetosphere in the significant correlation between lightning and the By component of the HMF (SSN) in the South Atlantic Anomaly.
Southwestward propagating quasi-biweekly oscillations over the South-West Indian Ocean during boreal winter: Characteristics and propagation mechanism
Authors: Ghatak Sambrita , Sukhatme Jai
Published: August 2024

Abstract. An analysis of outgoing longwave radiation (OLR) and winds over the South-West Indian Ocean (SWIO) yields regular, poleward propagating, large-scale, convectively coupled systems of alternating cyclonic and anticyclonic circulation with a quasi-biweekly period during boreal winter. Composites from 30 years (1980/81–2009/10) of OLR and reanalysis data show well-formed rotational gyres in the lower troposphere (700 hPa) that can be tracked from near the equator to almost 30° S appearing west of Sumatra and propagating towards Madagascar, i.e., with mean southwest propagation. The gyres show a marked northwest-southeast tilt, giving rise to a northeast-southwest oriented wavetrain. The scale of the gyres is about 30°–35°, their period is 14–18 days and they have a westward phase speed of approximately 3.5 ms-1. The group velocity of these wave packets is near-zero. In early stages, the gyres are associated with weak convection, but when they move poleward and cross 10° S, convective coupling is enhanced. Velocity fields and OLR indicate that the maxima of moist convective activity lies in the eastern sector of the gyres and a comparison between column-integrated moisture and OLR anomalies shows they are highly collocated, indicating the applicability of the moisture mode framework. A moisture budget reveals that once the gyres reach 10°–20° S, moistening is mainly due to northerlies in the eastern sector of the cyclonic gyre acting on the meridional gradient of background moisture, which eventually gives rise to anomalous convection in this region. This moistening process continues up to 30° S while the gyres traverse southwestward. Subsequently, background easterlies advect anomalous moisture and along with moistening via so-called 'column-processes', convection is observed to extend inside the gyre from the eastern side. A vorticity budget reveals that the β effect plays a leading role in the south-westward propagation, horizontal advection assists the westward movement of vorticity anomalies due to prevailing easterlies and moist coupling (via stretching) is important in reducing the speed of propagation of this mode. In fact, the relatively slow southwestward movement of the system is because moist coupling reduces the effect of β and horizontal advection terms. Moreover, as convection primarily takes place on the eastern side of the vortex, and somewhat inside the vortex too, it also follows a southwestward path along with the QBWO vortices.
Language-Based Nationalism: A Historical Analysis of Bengali Language Movement 1952
Authors: Hassan Ahmad
Published: August 2024

The paper examines the Bengali language movement in 1952 as the base of Bengali nationalism under the theoretical framework of language and nationalism. The idea of “one nation, one language”, in linguistically diverse regions like Pakistan, often results in the state’s oppressive policies to suppress the other languages and neglect the sentiments associated with them. Bengali language movement got its base right after the creation of Pakistan but gained its momentum in 1952. The state’s obvious response was suppression, resulting in converting the language movement into a nationalist ideology, which provided the base for the separation of East Pakistan in 1971. The paper qualitatively argues that the colonial impression of adopting one language as a national symbol resulted in making Urdu Pakistan’s national language; this colonial notion developed a sense of deprivation among the regional languages like Bengali with rich historical and cultural background, stemming from the idea of separate nationalism.
Los ratios financieros y su relación con la rentabilidad en una empresa de maquinaria pesada
Authors: Marchena Omar
Published: August 2024

El objetivo de la investigación es determinar la relación entre los indicadores financieros de actividad, liquidez y endeudamiento con la rentabilidad en una empresa del sector de venta y alquiler de maquinaria pesada. Para abordarlo, se lleva a cabo un estudio de caso en una empresa peruana. El enfoque utilizado es cuantitativo no experimental, basado en información secundaria (Estados Financieros) y con un diseño longitudinal (2015 a 2024). Según los resultados, la rentabilidad aproximada por el margen bruto y el margen neto se correlaciona positivamente con el promedio de ventas; mientras que los indicadores de liquidez (rotación de inventarios, período promedio de pago) se vinculan negativamente con diversos ratios de rentabilidad. Por último, la rentabilidad calculada como margen operativo no muestra relación estadísticamente significativa con ninguno de los indicadores de actividad, liquidez o endeudamiento. Los hallazgos son de utilidad para mejorar la rentabilidad de la empresa estudiada trabajando sobre los ratios que la afectan. Además, la investigación puede ser útil como modelo para la aplicación del análisis financiero para la toma de decisiones en diferentes organizaciones.

Authors: Jugón Mónica , Pastor Sandra , Raffaelli Pablo , Mastropierro Mariano , Frosinini Joana
Published: August 2024

Las empresas argentinas incorporan el tema del desarrollo sostenible en sus decisiones estratégicas por lo que resulta de interés analizar sus reportes y relevar lo que divulgan, en forma de definiciones y acciones. Por tal motivo, el objetivo del trabajo consiste en identificar si la divulgación que realizan las empresas sobre sostenibilidad en los reportes y/o memorias demuestra coherencia con lo que plantean a nivel estratégico, en dichos documentos. Para ello se hace un análisis de contenido cualitativo, exploratorio, descriptivo y reflexivo de los reportes de las once empresas argentinas adheridas al Pacto Global que participaron de su Programa Acelerador Sustainable Development Goals Ambition, en el año 2021. Con los resultados relevados se puede confirmar la consistencia y alineación de su accionar con las definiciones estratégicas sobre sostenibilidad. Además, es posible concluir que, dado el amplio campo de actuación que plantean, se pueden realizar estudios sobre materialidad, medición de impactos en la cadena de valor, entre otros.
Systematic Review of Bespoke Techniques of Software Fault Prediction: Machine Learning and Conventional Techniques
Authors: Tajinder Pal Singh
Published: August 2024

Software fault prediction is the practice of creating frameworks that software professionals are able to employ in the early stages of the software development life cycle to detect troubling constructs related to modules or classes. Several techniques have been suggested in the past for this purpose, the majority of which relied on lengthy mathematical models that did not appear to be suited for the current challenge. With technological advances, artificial intelligence (AI) modeling, also known as soft computing approaches, unlike conventional models, is gaining attention in research as it requires less processing and anticipates results quickly. In this paper, the author attempts to review conventional and machine learning techniques used previously for software fault prediction. For this review, data has been collected from various reputed library, such as IEEE Xplore. The present article has analyzed the various papers published from 2018 onward on the use of various conventional and non-conventional techniques. The extensive study’s analysis given in this article will be of great interest to academicians and professionals working in the field of software fault prediction in determining in which situations they need to apply which technique for the best results.

Niemeyer
Authors: Benoit Alexandre
Published: August 2024

Escrito como uma homenagem ao centenário do arquiteto Oscar Niemeyer, este texto procura se opor as interpretações ditas marxistas de que sua obra esta distante da realidade brasileira e que o seu sentido poético ficou aprisionado em uma modernidade apenas cabível na utopia desenvolvimentista dos anos 60. Procuro mostrar a partir de Marx e das vanguardas europeias como, na verdade, Niemeyer supera a utopia da técnica redentora do capitalismo (presente no discurso das vanguardas) desenvolvendo uma poética das formas livres cujo sentido se vincula diretamente às potencialidades do Brasil, como um país sem passado, onde como diz o próprio arquiteto, "tudo esta por se fazer", cujo destino é "construir hoje o passado de amanhã". Busco demonstrar ainda que mais do que nunca é necessário retomar a utopia grandiosa dos espaços de Niemeyer para se opor ao pragmatismo dos críticos ditos marxistas que contrários a Niemeyer apoiam ou legitimam ações conformistas (e catastróficas) de reformar a cidade capitalista em ruínas.

Uma leitura crítica dos conceitos de mundialização do capital e de regime de acumulação com predominância financeira
Authors: Klagsbrunn Victor Hugo
Published: August 2024

O termo globalização, pouco preciso mas largamente utilizado, merece certamente uma avaliação crítica. Na academia e entre a opinião pública, uma das críticas mais difundidas é a de François Chesnais, que propõe a utilização da expressão alternativa de mundialização do capital para descrever o capitalismo contemporâneo. Este seria atualmente caracterizado por um regime financeirizado de acumulação. Suas teses são desenvolvidas mencionando conceitos cunhados por Karl Marx e, por isso, os fundamentos teóricos e os conceitos utilizados por Chesnais são analisados, neste texto, criticamente à luz da teoria daquele autor. Conclui-se que a aplicação do instrumental desenvolvido por Chesnais leva a uma análise unilateral e formal do movimento do capital em sua fase pós-1980. Nela o capital financeiro surge como principal e único responsável pelo desenvolvimento do sistema, com um papel basicamente predador no capitalismo contemporâneo e deixando totalmente de lado a produção, fundamento do sistema capitalista, e sua relação contraditória com a esfera financeira.
Gramsci e Labriola
Authors: Vanzulli Marco
Published: August 2024

Trata-se nesse texto de ver mais uma vez qual foi a incidência do idealismo, do subjetivismo sobre o pensamento de Gramsci, através da comparação com Labriola, o primeiro teórico do marxismo italiano, ao qual o político sardo costuma ser desembaraçadamente assimilado. A obra do jovem Gramsci exibe uma relevante influência do neoidealismo italiano através da qual abre mão de uma concepção objetivista da história para ressaltar os aspectos voluntaristas e consciencialistas da própria ação histórica e revolucionária; a crítica do positivismo e do naturalismo torna-se em Gramsci recusa do objetivismo histórico tout court. Essa influência é só fortalecida pelo conhecimento do pensamento de Lenin, e permanece nas reflexões dos Quaderni del carcere. É, todavia, graças a essa base idealista que o pensamento político de Gramsci pode alcançar toda sua originalidade na teoria da hegemonia e da conquista da sociedade civil.

As respostas capitalista e socialista à crise ecológica
Authors: Wallis Victor
Published: August 2024

A acumulação capitalista choca-se frontalmente com as prioridades ecológicas. Os defensores e os praticantes do “capitalismo verde” procuram alcançar objetivos ambientalistas no interior de uma estrutura definida pelo mercado. Certos melhoramentos são possíveis por tais meios, porém apenas em restritos limites. Isso se aplica não apenas a medidas empresariais, mas também a políticas governamentais, na medida em que envolvem a atribuição de valor de troca a processos naturais. Alguns autores de esquerda conceberam tal abordagem como a única resposta politicamente viável para a crise atual. Este artigo critica essa concepção, e a seguir trata de três dimensões importantes de uma agenda ecológica que estão fora do alcance de estratégias mercadológicas: 1) questionar o crescimento e a inovação perpétuos e o aumento da produção de lixo; 2) acabar com o militarismo e o imperialismo; e 3) redefinir “a boa vida”. Ao final, expõem-se alguns exemplos de realizações ecológicas positivas em contextos socialistas.

Prolegômenos para uma ontologia do ser social
Authors: Lessa Sergio
Published: August 2024

No início dos anos de 1960, ao terminar o primeiro volume de sua Estética, Lukács decidiu redigir uma Ética. Era preciso, para conferir um fundamento materialista à ética, delimitar os fundamentos ontológicos do processo histórico de sua gênese e desenvolvimento a partir do trabalho – o que o levou a investigar os fundamentos da reprodução social. Essa investigação resultou no manuscrito intitulado Para uma ontologia do ser social, o qual foi debatido com seus discípulos em Budapeste. Desse debate, pouco sabemos – e a sua avaliação mais consistente é a apresentação de Nicolas Tertulian à edição italiana dos Prolegômenos (publicado como posfácio da edição brasileira dos Prolegômenos e, pela primeira vez em língua portuguesa, na Crítica Marxista n.3). Após esse debate, Lukács redigiu uma introdução, um prolegômeno, ao manuscrito já redigido. É este Prolegômenos a uma ontologia do ser social o texto publicado pela Editora Boitempo. Tal como a Ontologia, também esta obra ficou inacabada, sendo de mais difícil compreensão do que o texto que pretende introduzir. Por isso, talvez houvesse sido mais interessante iniciar a publicação do conjunto da ontologia lukácsiana pela Ontologia do ser social – mas isso, no longo prazo, não deverá ter grande importância.
