MAC Protocols for mmWave Communication: A Comparative Survey
Authors: Tarafder Pulok , Choi Wooyeol
Published: May 2022

With the increase in the number of connected devices, to facilitate more users with high-speed transfer rate and enormous bandwidth, millimeter-wave (mmWave) technology has become one of the promising research sectors in both industry and academia. Owing to the advancements in 5G communication, traditional physical (PHY) layer-based solutions are becoming obsolete. Resource allocation, interference management, anti-blockage, and deafness are crucial problems needing resolution for designing modern mmWave communication network architectures. Consequently, comparatively new approaches such as medium access control (MAC) protocol-based utilization can help meet the advancement requirements. A MAC layer accesses channels and prepares the data frames for transmission to all connected devices, which is even more significant in very high frequency bands, i.e., in the mmWave spectrum. Moreover, different MAC protocols have their unique limitations and characteristics. In this survey, to deal with the above challenges and address the limitations revolving around the MAC layers of mmWave communication systems, we investigated the existing state-of-the-art MAC protocols, related surveys, and solutions available for mmWave frequency. Moreover, we performed a categorized qualitative comparison of the state-of-the-art protocols and finally examined the probable approaches to alleviate the critical challenges in future research.

Published: May 2022

Acoustic detection technology is a new method for early monitoring of wood-boring pests, and the effective denoising methods are the premise of acoustic detection in forests. This paper used sensors to record Semanotus bifasciatus larval feeding sounds and various environmental noises, and two kinds of sounds were mixed to obtain the noisy feeding sounds with controllable noise intensity. Then, the time domain denoising models and frequency domain denoising models were designed, and the denoising effects were compared using the metrics of a signal-to-noise ratio (SNR), a segment signal-noise ratio (SegSNR), and log spectral distance (LSD). In the experiments, the average SNR increment could achieve 17.53 dB and 11.10 dB using the in the test data using the time domain features and frequency domain features, respectively. The average SegSNR increment achieved 18.59 dB and 12.04 dB, respectively, and the average LSD between pure feeding sounds and denoised feeding sounds were 0.85 dB and 0.84 dB, respectively. The experimental results demonstrated that the denoising models based on artificial intelligence were effective methods for S. bifasciatus larval feeding sounds, and the overall denoising effect was more significant, especially at low SNRs. In view of that, the denoising models using time domain features were more suitable for the forest area and quarantine environment with complex noise types and large noise interference.

Published: May 2022

Long Term Evolution-Metro (LTE-M), as a special communication system for train control, has strict requirements on adjacent channel interference (ACI). According to the 3rd Generation Partnership Project (3GPP) protocol of the European Telecommunications Standards Institute (ETSI) standards, this paper presents the required isolation degree for LTE-M systems to resist ACI. Aiming at the scenario of leaky cable transmission and antenna transmission adopted by the underground LTE-M system of the subway, the isolation degree required for LTE-M system deployment is deduced by combining the channel description with the principle of ACI. For the coexistence of a LTE-M system and an adjacent cellular system in a subway ground scenario, the Monte-Carlo (MC) method is used to simulate several conceivable scenarios of the LTE-M system and the adjacent frequency cellular system. In addition, the throughput loss of the LTE-M system is estimated by considering signal to interference plus noise ratio (SINR). Simulation results demonstrate that adjacent frequency user equipment (UE) has negligible small interference with the LTE-M underground system when using the leaky cable radiation pattern, whereas for the LTE-M ground system, the main interference comes from the adjacent frequency UE to the LTE-M base station (BS). Finally, interference avoidance solutions are presented, which can be utilized as a reference in the design and deployment of LTE-M systems in the rail transit environment.

Published: May 2022

The relationship between human capital and innovative performance in service companies has been studied in countries with fast-growing economies and knowledge-intensive companies, but little evidence exists in other contexts. The research examined the relationship between human capital variables and the innovative performance of Ecuadorian service companies. The methodology is quantitative. It is a non-experimental, cross-sectional investigation, and data from Ecuador from the national survey of innovation activities 2015 were used. A bivariate probit regression was performed. The results indicate that the variable training in innovation activities is positively related to service innovation, but not to process innovation, because service innovation requires a greater development of skills and abilities than process innovation in these activities. Company workers and the variable workers with higher education are positively related to process innovation, but not to service innovation. The research contributes to the gap in the literature on the relationship between human capital variables and innovative performance and provides empirical evidence of the relationship in developing countries where evidence is scarce. The research has practical implications for managers and administrators of service companies: Increasing training in innovation activities can increase the potential for service innovation and increasing workers with higher education increases the innovative potential in the processes in these companies. The originality of this study is that it presents evidence of this relationship in a developing country that has companies in a different context such as scarcity of qualified human resources, low level of R&D investment, and companies with a medium level of knowledge complexity, since the evidence focuses on companies in developed countries and knowledge-intensive companies.
Inframammary Fold Banking of the Non-Dominant Superficial Epigastric Vein (SIEV) in Unilateral Autologous Breast Reconstruction: A Simple and Helpful Backup Option for Revision Surgery
Authors: Hirche Christoph , Kneser Ulrich , Fischer Sebastian
Published: May 2022

Free flaps from the lower abdomen represent the workhorses of modern autologous, microvascular breast reconstruction. Rare signs of venous congestion often become evident during the primary index operation, but a secondary shift of the initially dominant drainage of the DIEV system to the SIEV system with consequent malperfusion is a feared, rare event requiring urgent decision, and complex skill using vein grafts and additional anastomosis to restore a sufficient venous outflow. For secondary anastomosis of the SIEV, especially in stacked flaps, a vein graft to the DIEV or retrograde IMV may be necessary, but this requires an additional donor site, thus prolonging procedure time during the emergency operation and resulting in additional scars of the graft’s donor site. We report on a versatile, easy technique of scheduled inframammary fold banking of the dissected, flushed, and clipped non-dominant superficial epigastric vein (SIEV) in unilateral autologous breast reconstruction during the index operation. The banked graft may service as an easy and convenient accessible vein graft in the rare event of secondary shifting of the initial dominant drainage of the DIEV to the SIEV system with the need for urgent re-operation. We retrospectively evaluated the management and outcome of all suitable patients receiving autologous breast reconstruction with a unilateral abdominal DIEP or MS-Tram flap accompanied by banking of the SIEV in the breast pocket between 2017 and 2020 in the present study. In two out of 42 patients (4.8%) receiving autologous breast reconstruction with an abdominal DIEP or MS-TRAM flap with banking of the SIEV in the breast pocket, secondary malperfusion of the flap with progressive venous congestion occurred during the first 48 h perioperatively, between 2 and 37 (mean: 19.5) hours after skin closure. In both cases malperfusion was due to secondary SIEV system dominance, and the banked vein was used as an interpositional graft to the retrograde IMV (case 1) or the DIEV (case 2). Revision surgery lasted between 95 and 121 (mean: 108) minutes without the need for further vein graft harvesting, and further healing was uneventful. Based on the limited cases, inframammary fold banking of the non-dominant SIEV is a versatile, beneficial, and feasible concept with scarce additional dissection time and can be done in all unilateral breast reconstructions to have a reliable graft for emergency re-exploration. It is a useful approach in the context of spare part surgery and tissue banking to safeguard against the rare instance of venous congestion and need for an interpositional graft.
A Dialectics of Ecology and Design in the Reform of Contemporary Landscapes
Authors: Pasini Roberto
Published: May 2022

In the face of the impending crisis of the biosphere, the debate in the design disciplines has been attracted to the disciplinary precincts of ecology and its dynamics, while the notion of landscape continuum tends to englobe that of territory. The intention to contaminate traditional land transformation approaches with sustainable approaches derived from landscape ecology has been recorded. At the same time, a particular focus on the study of the metabolism of territorial entities has emerged beside the traditional interest in the study of their morphology. This paper tackles the theme of the special issue on ‘Constructed Natures: Shaping Ecologies through Landscape Design’ by adopting the recurrent method of human sciences, via discursive analysis of literature and case-studies. First, the paper characterizes the origins and reasons for the ecological crisis. Secondly, we review the recently growing interest developed in the landscape design disciplines for the ecological/metabolic aspects vis-à-vis the traditional focus on morphological/compositive aspects. Finally, we review three case-studies representative of distinct contemporary approaches to landscape reform responding in distinct manners to the impending ecological crisis. The compared analysis of the case-studies identifies strengths and weaknesses of the different approaches. The paper’s conclusions summarize the profile of a virtuous approach to the reform landscape apparatuses and draw possible lines of further research and experimentation in the field of landscape design and its relationship to ecology.
Simulating PM2.5 Concentrations during New Year in Cuenca, Ecuador: Effects of Advancing the Time of Burning Activities
Authors: Parra René , Saud Claudia , Espinoza Claudia
Published: May 2022

Fine particulate matter (PM2.5) is dangerous to human health. At midnight on 31 December, in Ecuadorian cities, people burn puppets and fireworks, emitting high amounts of PM2.5. On 1 January 2022, concentrations between 27.3 and 40.6 µg m−3 (maximum mean over 24 h) were measured in Cuenca, an Andean city located in southern Ecuador; these are higher than 15 µg m−3, the current World Health Organization guideline. We estimated the corresponding PM2.5 emissions and used them as an input to the Weather Research and Forecasting with Chemistry (WRF-Chem 3.2) model to simulate the change in PM2.5 concentrations, assuming these emissions started at 18:00 LT or 21:00 LT on 31 December 2021. On average, PM2.5 concentrations decreased by 51.4% and 33.2%. Similar modeling exercises were completed for 2016 to 2021, providing mean decreases between 21.4% and 61.0% if emissions started at 18:00 LT. Lower mean reductions, between 2.3% and 40.7%, or even local increases, were computed for emissions beginning at 21:00 LT. Reductions occurred through better atmospheric conditions to disperse PM2.5 compared to midnight. Advancing the burning time can help reduce the health effects of PM2.5 emissions on 31 December.
Partnerships for Private Transit Investment—The History and Practice of Private Transit Infrastructure with a Case Study in Perth, Australia
Authors: Davies-Slate Sebastian , Newman Peter
Published: May 2022

Urban transit planning is going through a transition to greater private investment in many parts of the world and is now on the agenda in Australia. After showing examples of private investment in transit globally, the paper focuses on historical case studies of private rail investment in Western Australia. These case studies mirror the historical experience in rapidly growing railway cities in Europe, North America, and Asia (particularly Japan), and also the land grant railways that facilitated settlement in North America. The Western Australian experience is noteworthy for the small but rapidly growing populations of the settlements involved, suggesting that growth, rather than size, is the key to successfully raising funding for railways through land development. The paper shows through the history of transport, with particular reference to Perth, that the practice of private infrastructure provision can provide lessons for how to enable this again. It suggests that new partnerships with private transport investment as set out in the Federal Government City Deal process, should create many more opportunities to improve the future of cities through once again integrating transit, land development, and private finance.

Healthcare workers are at high risk of influenza virus infection as well as of transmitting the infection to vulnerable patients who may be at high risk of severe illness. The aim of this cross-sectional study was to investigate the prevalence and related factors of influenza vaccination coverage (2020–2021flu season), among members of the Athens Medical Association in Greece. This survey employed secondary analysis data from a questionnaire-based dataset on COVID-19 vaccination coverage and associated factors from surveyed doctors, registered within the largest medical association in Greece. All members were invited to participate in the anonymous online questionnaire-based survey over the period of 25 February to 13 March 2021. Finally, 1993 physicians (60% males; 40% females) participated in the study. Influenza vaccination coverage was estimated at 76%. Logistic regression analysis demonstrated that older age (OR = 1.02; 95% C.I. = 1.01–1.03), history of COVID-19 vaccination (OR = 2.71; 95% C.I. = 2.07–3.56) and perception that vaccines in general are safe (OR = 16.49; 95% C.I. = 4.51–60.25) were found to be independently associated factors with the likelihood of influenza vaccination coverage. Public health authorities should maximize efforts and undertake additional actions in order to increase the percentage of physicians/health care workers (HCWs) being immunized against influenza. The current COVID-19 pandemic offers an opportunity to focus on tailored initiatives and interventions aiming to improve the influenza vaccination coverage of HCWs in a spirit of synergy and cooperation.

The purpose of this study was to evaluate the efficacy and safety of the Moderna-1273 mRNA vaccine for SARS-CoV-2 in patients with immune-mediated diseases under different treatments. Anti-trimeric spike protein antibodies were tested in 287 patients with rheumatic or autoimmune diseases (10% receiving mycophenolate mofetil, 15% low-dose glucocorticoids, 21% methotrexate, and 58% biologic/targeted synthetic drugs) at baseline and in 219 (76%) 4 weeks after the second Moderna-1273 mRNA vaccine dose. Family members or caretakers were enrolled as the controls. The neutralizing serum activity against SARS-CoV-2-G614, alpha, and beta variants in vitro and the cytotoxic T cell response to SARS-CoV-2 peptides were determined in a subgroup of patients and controls. Anti-SARS-CoV-2 antibody development, i.e., seroconversion, was observed in 69% of the mycophenolate-treated patients compared to 100% of both the patients taking other treatments and the controls (p < 0.0001). A dose-dependent impairment of the humoral response was observed in the mycophenolate-treated patients. A daily dose of >1 g at vaccination was a significant risk factor for non-seroconversion (ROC AUC 0.89, 95% CI 0.80–98, p < 0.0001). Moreover, in the seroconverted patients, a daily dose of >1 g of mycophenolate was associated with significantly lower anti-SARS-CoV-2 antibody titers, showing slightly reduced neutralizing serum activity but a comparable cytotoxic response compared to other immunosuppressants. In non-seroconverted patients treated with mycophenolate at a daily dose of >1 g, the cytotoxic activity elicited by viral peptides was also impaired. Mycophenolate treatment affects the Moderna-1273 mRNA vaccine immunogenicity in a dose-dependent manner, independent of rheumatological disease.

Adolescents can develop a severe form of Coronavirus disease 2019 (COVID-19), especially with underlying comorbidities. No study has examined the efficacy or effectiveness of inactivated COVID-19 vaccines in adolescents. This single-center, prospective cohort study was performed to evaluate the safety and effectiveness of an inactivated COVID-19 vaccine in adolescents using the immunobridging approach at Chulabhorn Hospital. The key eligibility criterion was a healthy clinical condition or stable pre-existing comorbidity. The anti-receptor-binding domain (anti-RBD) antibody concentration at 4 weeks after dose 2 of the vaccine was compared between participants aged 12 to 17 years and those aged 18 to 30 years. Safety profiles included adverse events within 7 days after each dose of the vaccine and any adverse events through 1 month after dose 2 of the vaccine. In the adolescent and adult cohorts, the geometric mean concentration of anti-RBD antibody was 102.9 binding antibody unit (BAU)/mL (95% CI, 91.0–116.4) and 36.9 BAU/mL (95% CI, 30.9–44.0), respectively. The geometric mean ratio of the adolescent cohort was 2.79 (95% CI, 2.25–3.46, p < 0.0001) compared with the adult cohort, meeting the non-inferiority criterion. The reactogenicity was slightly lower in the adolescent than in the adult cohort. No serious adverse events occurred. The inactivated COVID-19 vaccine appears safe and effective in adolescents.

Respiratory syncytial virus (RSV) is an important pathogen that causes acute respiratory tract infections in children. To understand the epidemiological and clinical characteristics of RSV in children, we analyzed the RSV diagnostic testing results from the 2014–2018 surveillance of acute respiratory infections in China. Among children aged <5 years, RSV incidence during 2014–2018 was 17.3% (3449/19,898), and 89.1% of RSV-positive individuals were inpatients. Children aged < 6 months had a high proportion in RSV infected individual (n = 1234; 35.8%). The highest RSV detection rate was in winter, RSV-A and RSV-B co-circulated year-round and jointly prevailed in 2015–2016. Cough was the common symptom of RSV infection 93.2% (3216/3449). Compared with older children, those aged <6 months were more likely to show breathing difficulty or lung rale that further developed into bronchopneumonia (p < 0.001). The symptoms such as cough, running nose, and diarrhea had significant differences between the RSV-A and RSV-B groups. The rate of RSV co-detection with other viruses or bacteria was 35.4%. Those coinfected with other viruses had a significantly higher incidence of fever, whereas those coinfected with bacteria had higher incidences of breathing difficulty and severe pneumonia. Our findings highlight the need for accumulating epidemiological information for the prevention and control of RSV.

Published: May 2022

A preventive vaccination program is in operation in Poland. There are mandatory vaccinations for Polish residents under the age of 19 years. The law provides for financial penalties for parents who refuse to vaccinate their children. The aim of this study was to describe the attitudes of Polish residents aged 15–39 years to mandatory preventive vaccination and the level of acceptance for legal and financial sanctions for refusing mandatory vaccination of children. Materials and Methods: A face-to-face questionnaire-based study of a representative sample of 1560 residents of Poland aged 15–39 years. Data was collected in the fourth quarter of 2021. Results: In the study group, 51.5% of the respondents believed that preventive vaccination should be mandatory, and parents should have the right to decide only about additional vaccinations. Multivariate analyses (logistic regression) revealed a significant association between acceptance of mandatory vaccination and the following factors: positive COVID-19 vaccination status, self-declared religiosity, and having children. Of the 1560 respondents, 25.3% declared support for legal or financial sanctions for those refusing to vaccinate their children. In this group (n = 394), the highest percentage of respondents (59.4%) supported sanctions in the form of refusal to admit an unvaccinated child to a nursery or kindergarten. Conclusions: Despite preventive (mandatory) vaccination programs having been in operation in Poland since the 1960′s, only a little over 50% of adolescent Poles and young adults accept the vaccine mandate. Only 25% of this group declare their support for sanctions for refusing mandatory vaccination of children.

Longitudinal data comparing SARS-CoV-2 serology in individuals following infection and vaccination over 12 months are limited. This study compared the magnitude, decay, and variability in serum IgG, IgA, and neutralizing activity induced by natural infection (n = 218) or mRNA vaccination in SARS-CoV-2 naïve (n = 143) or experienced (n = 122) individuals over time using enzyme-linked immunosorbent assays and an in vitro virus neutralization assay. Serological responses were found to be highly variable after natural infection compared with vaccination but durable through 12 months. Antibody levels in vaccinated, SARS-CoV-2 naïve individuals peaked by 1 month then declined through 9 months, culminating in non-detectable SARS-CoV-2-specific serum IgA. Individuals with both infection and vaccination showed SARS-CoV-2-specific IgG and IgA levels that were more robust and slower to decline than the other groups; neutralizing activity remained highest in this group at 9 months past vaccination. These data reinforce the benefit of vaccination after SARS-CoV-2 recovery.

In the article the authors considered the criminal law norm enshrined in Article 145 of the Criminal Code of the Russian Federation, including for its compliance with international legislation on the protection of persons with family obligations. They note that, firstly, contrary to the proclaimed norms of international law, neither the basic law of our state nor st. 145 of the Criminal Code of the Russian Federation mention as injured fathers with children under 3 years of age. Secondly, the disposition itself of article 145 of the Criminal Code of the Russian Federation is defective due to the indication as a victim, along with a pregnant woman and a woman with not a single child, namely children under 3 years old. Thirdly, the authors note the softness of the sanctions of the norm in question compared, for example, with Art. 136 of the Criminal Code, which establishes a ban on discrimination on various grounds.

The library is a center of knowledge that must be managed properly and correctly in an educational institution. SLBN 1 Linggo Sari Baganti is a school where all kinds of activities get more attention from the government, one of which is through the library. various assistance, facilities and infrastructure in the form of a collection of books are always provided. However, the operation of the library at SLBN 1 Linggo Sari Baganti is currently still managed in a conventional way. Starting from the data collection process to borrowing books is still done manually. Causing activities to be slow, inefficient and errors tend to be repeated frequently. So the Design of a Library Information System at SLBN 1 Linggo Sari Baganti Using Visual Basic 2010 Programming Language and Supported by Mysql Database is the right solution to overcome these problems. The results of the evaluation of the library system that has been designed show that the library system has features of computerized automation of data processing, transactions and the creation of important reports that have made it easier for librarians to manage the library.

La retórica en cuestión
Authors: Garayalde Nicolás
Published: May 2022

Este ensayo se origina en una lectura del libro Barthes en cuestión, que incluye un artículo de Paul de Man a propósito del pensamiento barthesiano y otro de Judith Podlubne a propósito de la lectura demaniana de Barthes. A partir de allí, procuro continuar pensando las tensiones entre Barthes y de Man a partir de la siguiente hipótesis: la historia de la teoría literaria es la historia de una auto-impugnación de sus fundamentos ante al reconocimiento de la falta de correspondencia entre el signo y la cosa; reconocimiento que abrió camino a una incesante interacción entre la teoría de la lectura y el retorno de la retórica —abandonada en el siglo XIX—. En este marco, las diferencias entre Barthes y de Man se basan en las diferentes modalidades de retórica que asumen (de la elocutio, en uno; de los tropos, en el otro) y sus consecuentes críticas (una crítica como literatura, en uno; una epistemología negativa de la lectura, en el otro).
Computational Evaluation of the Effect of Build Orientation on Thermal Behavior and in-situ Martensite Decomposition for Laser Powder-Bed Fusion (LPBF) Process
Authors: YILDIZ Ayşe Kübra , MOLLAMAHMUTOGLU Mehmet , YILMAZ Oğuzhan
Published: May 2022

Laser powder bed fusion (LPBF), which is an additive manufacturing method, is a thermo-mechanical process in which instantaneously varying heat flow rates occur by moving a high-intensity laser beam. The high temperatures and cooling rates that occur throughout the process result in microstructures with brittle behavior. The microstructure and mechanical properties may be improved by controlling the cooling rates in the layers via build orientation. Since the process is on a microscale, it requires planning as it does not allow instant intervention. Therefore, numerical analysis can be helpful to determine the effect of different build orientations. In this study, the effect of different build orientations was emphasized. For this purpose, successive layers resulting in narrowing and expanding cross-sectional areas were investigated with a detailed thermal approach. Also, a martensite decomposition case, as a result of changing the build orientation for a geometry, was presented numerically. As a result, it is shown that build orientation has an effect on the heat distribution within the part. Some benefits of expanding the cross-sectional area have been determined. Specifically, it is found that the build orientation may also enable local martensite decomposition, contributing to a lamellar microstructure.

Cadmium, tin, iron, copper, and zinc in tea, rice, and liver samples, and standard reference materials (IRMM 804 Rice Flour, GBW 10010 Rice, Bovine Liver1577c and GBW 07605 Tea Leaves) were determined by using electrothermal and flame atomic absorption spectrometries. Cd and Sn in sample solutions were determined with electrothermal atomic absorption spectrometry by using palladium (Pd) as a matrix modifier. Pyrolysis and atomization temperatures and pyrolysis times of Cd and Sn in sample solutions were optimized in the absence or presence of Pd. Pyrolysis temperatures of Cd and Sn found in the presence of Pd were 800°C and 1200°C, respectively. Iron, Cu, and Zn in samples were determined by flame atomic absorption spectrometry. The accuracy and precision of the method were validated by determining elements in standard reference materials. Limits of detection for Sn, Cd, Fe, Cu, and Zn were found as 0.66, 0.26, 2.0, 1.9, and 1.2 μg/L, respectively. Concentrations of elements found in samples were compared with maximum values reported by World Health Organization (WHO) and other studies.

“Durante nuestra gestión al frente del Ministerio de Agricultura y Desarrollo Rural (agosto de 2002-febrero de 2005), adoptamos como máxima prioridad las tareas que desde el campo resultaba imperativo adelantar, bajo el principio de la anticipación, a fin de enfrentar con eficacia y oportunamente las ostensibles secuelas del cambio climático global, tomando el mejor provecho posible de la dotación de los recursos naturales del país. Una iniciativa que, de haberse puesto en plena marcha, habría sido la más importante contribución de Colombia a los compromisos asumidos en el seno del acuerdo de París de 2015. La idea central se concretó en un minucioso plan orientado al renacimiento de la Orioquia Alta de Colombia, basado en su conversión en un gran sumidero de gases de efecto invernadero, bajo las regulaciones de la Organización de Naciones Unidas, y conectado con el mercado internacional de certificados de reducción de sus emisiones”.

Rudiments of contemporary fantasy in Madame d'Aulnoy's fairy tales
Authors: Ribeiro Filho Paulo César
Published: May 2022

Sabe-se que a literatura de fantasia contemporânea carrega consigo filamentos narrativos provenientes do antigo e longevo arcabouço temático dos contos de fadas tradicionais e demais contos maravilhosos; personagens e motes advindos dessa profícua tradição literária têm sido comumente refigurados e reaproveitados na atualidade. O objetivo do presente artigo é lançar reflexões teóricas e analíticas acerca de uma nova hipótese interpretativa: a de que uma série de rudimentos estruturais da fantasia contemporânea estariam presentes nos contos de fadas literários de Marie-Catherine Le Jumel de Barneville, a Madame d’Aulnoy (1650?-1705), cunhadora do termo “conto de fadas” e autora do primeiro conto de fadas literário de que se tem notícia. Para cotejar tal possibilidade, conjuga-se as contribuições teóricas de Bottigheimer (2019), Mendlesohn (2008) e Matangrano (2021) em contraponto com os postulados de Todorov (1973) sobre a estrutura narratológica do conto de fadas. Pretende-se, além de demonstrar a pertinência da referida hipótese, lançar luzes sobre a obra ainda pouco conhecida de Madame d’Aulnoy (sobretudo para os leitores de língua portuguesa), bem como sobre a contística feérica de autoria feminina do século XVII francês.
