An Instruction Set Extension to Support Software-Based Masking
Authors: Gao Si , Großschädl Johann , Marshall Ben , Page Dan , Pham Thinh , Regazzoni Francesco
Published: August 2021

In both hardware and software, masking can represent an effective means of hardening an implementation against side-channel attack vectors such as Differential Power Analysis (DPA). Focusing on software, however, the use of masking can present various challenges: specifically, it often 1) requires significant effort to translate any theoretical security properties into practice, and, even then, 2) imposes a significant overhead in terms of efficiency. To address both challenges, this paper explores the use of an Instruction Set Extension (ISE) to support masking in software-based implementations of a range of (symmetric) cryptographic kernels including AES: we design, implement, and evaluate such an ISE, using RISC-V as the base ISA. Our ISE-supported first-order masked implementation of AES, for example, is an order of magnitude more efficient than a software-only alternative with respect to both execution latency and memory footprint; this renders it comparable to an unmasked implementation using the same metrics, but also first-order secure.
Revealing the Weakness of Addition Chain Based Masked SBox Implementations
Authors: Ming Jingdian , Li Huizhong , Zhou Yongbin , Cheng Wei , Qiao Zehua
Published: August 2021

Addition chain is a well-known approach for implementing higher-order masked SBoxes. However, this approach induces more computations of intermediate monomials over F2n, which in turn leak more information related to the sensitive variables and may decrease its side-channel resistance consequently. In this paper, we introduce a new notion named polygon degree to measure the resistance of monomial computations. With the help of this notion, we select several typical addition chain implementations with the strongest or the weakest resistance. In practical experiments based on an ARM Cortex-M4 architecture, we collect power and electromagnetic traces in consideration of different noise levels. The results show that the resistance of the weakest masked SBox implementation is close to that of an unprotected implementation, while the strongest one can also be broken with fewer than 1,500 traces due to extra leakages. Moreover, we study the resistance of addition chain implementations against profiled attacks. We find that some monomials with smaller output size leak more information than the SBox output. The work by Duc et al. at JOC 2019 showed that for a balanced function, the smaller the output size is, the less information is leaked. Thus, our attacks demonstrate that this property of balanced functions does not apply to unbalanced functions.
Structural Attack (and Repair) of Diffused-Input-Blocked-Output White-Box Cryptography
Authors: Carlet Claude , Guilley Sylvain , Mesnager Sihem
Published: August 2021

In some practical enciphering frameworks, operational constraints may require that a secret key be embedded into the cryptographic algorithm. Such implementations are referred to as White-Box Cryptography (WBC). One technique consists of the algorithm’s tabulation specialized for its key, followed by obfuscating the resulting tables. The obfuscation consists of the application of invertible diffusion and confusion layers at the interface between tables so that the analysis of input/output does not provide exploitable information about the concealed key material.Several such protections have been proposed in the past and already cryptanalyzed thanks to a complete WBC scheme analysis. In this article, we study a particular pattern for local protection (which can be leveraged for robust WBC); we formalize it as DIBO (for Diffused-Input-Blocked-Output). This notion has been explored (albeit without having been nicknamed DIBO) in previous works. However, we notice that guidelines to adequately select the invertible diffusion ∅and the blocked bijections B were missing. Therefore, all choices for ∅ and B were assumed as suitable. Actually, we show that most configurations can be attacked, and we even give mathematical proof for the attack. The cryptanalysis tool is the number of zeros in a Walsh-Hadamard spectrum. This “spectral distinguisher” improves on top of the previously known one (Sasdrich, Moradi, Güneysu, at FSE 2016). However, we show that such an attack does not work always (even if it works most of the time).Therefore, on the defense side, we give a straightforward rationale for the WBC implementations to be secure against such spectral attacks: the random diffusion part ∅ shall be selected such that the rank of each restriction to bytes is full. In AES’s case, this seldom happens if ∅ is selected at random as a linear bijection of F322. Thus, specific care shall be taken. Notice that the entropy of the resulting ∅ (suitable for WBC against spectral attacks) is still sufficient to design acceptable WBC schemes.
Batching CSIDH Group Actions using AVX-512

Published: August 2021

Commutative Supersingular Isogeny Diffie-Hellman (or CSIDH for short) is a recently-proposed post-quantum key establishment scheme that belongs to the family of isogeny-based cryptosystems. The CSIDH protocol is based on the action of an ideal class group on a set of supersingular elliptic curves and comes with some very attractive features, e.g. the ability to serve as a “drop-in” replacement for the standard elliptic curve Diffie-Hellman protocol. Unfortunately, the execution time of CSIDH is prohibitively high for many real-world applications, mainly due to the enormous computational cost of the underlying group action. Consequently, there is a strong demand for optimizations that increase the efficiency of the class group action evaluation, which is not only important for CSIDH, but also for related cryptosystems like the signature schemes CSI-FiSh and SeaSign. In this paper, we explore how the AVX-512 vector extensions (incl. AVX-512F and AVX-512IFMA) can be utilized to optimize constant-time evaluation of the CSIDH-512 class group action with the goal of, respectively, maximizing throughput and minimizing latency. We introduce different approaches for batching group actions and computing them in SIMD fashion on modern Intel processors. In particular, we present a hybrid batching technique that, when combined with optimized (8 × 1)-way prime-field arithmetic, increases the throughput by a factor of 3.64 compared to a state-of-the-art (non-vectorized) x64 implementation. On the other hand, vectorization in a 2-way fashion aimed to reduce latency makes our AVX-512 implementation of the group action evaluation about 1.54 times faster than the state-of-the-art. To the best of our knowledge, this paper is the first to demonstrate the high potential of using vector instructions to increase the throughput (resp. decrease the latency) of constant-time CSIDH.

Estudo comparativo da resistência de união metal/resina entre duas técnicas de colagem de tubos ortodônticos
Authors: Carpio Eduardo Efraín Vivanco , Alessio Junior Luiz Eduardo
Published: August 2021

Inúmeros estudos demonstram que os adesivos têm excelente união ao esmalte, portanto o objetivo deste estudo é avaliar a união na interface entre o metal do tubo ortodôntico e a resina. Neste estudo da resistência ao cisalhamento será utilizado resina Transbond XT 3M™ em 40 tubos ortodônticos para molares inferiores simples slot 0.022”, que serão divididos em dois grupos: 20 tubos ortodônticos para o Grupo Controle (GC) e 20 tubos ortodônticos para o Grupo Experimental (GP). No GC será adicionado uma camada de resina de cimentação ortodôntica de 1mm, seguido de fotopolimerização com 0 mm de distância por 10 segundos para evitar a contração máxima da resina, mais 20 segundos de fotopolimerização contínuo, usando uma lâmpada de 700 MW, e uma segunda camada de 2 mm retangular à forma da base do tubo ortodôntico para a aplicação do teste de cisalhamento. Para o Grupo Experimental (GP), a malha metálica da base do tubo foi condicionada com a aplicação de micro abrasão com jato de óxido de alumínio de 50 mícron, por 8 segundos a uma distância de 2 a 3 mm através da superfície da malha do tubo, a uma pressão de ar de 90 Pa, controlado por um barômetro de ar comprimido. Logo após foi realizada a remoção das impurezas do óxido de alumínio usando uma seringa de ar e água da unidade odontológica. Na superfície limpa foi aplicado o sistema Primer Adesivo Transbond XT™ com fotopolimerização por 10 segundos com luz LED contínua a 0mm, em seguida foi colocada a resina Transbond XT™ em 3 camadas de 1 mm, com 10 segundos de fotopolimerização a 0 mm. Todos os corpos de prova foram marcados e levados para a máquina de testes universal onde a força será aplicada à superfície da resina presa à malha do tubo ortodôntico, a uma distância de 0.8 mm da malha. São valores numéricos, portanto, o Teste t de Student para amostras independentes foi selecionado. Com base nos resultados obtidos, afirma-se que o Grupo Controle GC e o Grupo Experimental com o condicionamento de jato de óxido de alumínio às bases dos tubos ortodônticos, não apresentam diferença estatisticamente significante.

Tratamiento ortodóntico de agenesia bilateral de incisivos laterales superiores mediante mecánica de cierre de espacios: autoevaluación de satisfacción estética
Authors: Ron Toledo Andrea Verónica , Sobrinho Luís Gonzaga do Amaral , Cruz Emerson Flamarion da
Published: August 2021

El papel preponderante de la estética, y específicamente de los dientes, obligan a que los tratamientos ortodontico sean cada vez más estables y satisfactorios, no sólo desde el punto de vista funcional como lo juzga el profesional, sino también de satisfacción personal y autoimagen que es la forma como se auto percibe el mismo paciente. Proporcionar a los pacientes que sufren de Agenesia bilateral de incisivos laterales superiores, tratamientos multidisciplinarios que alcancen estos objetivos es fundamentais. El cierre de espacios evita la instalación de prótesis os implantes para la rehabilitación de los mismos, logrando finalizar los tratamientos integralmente sin importar que los pacientes no hayan terminado aún su crecimiento y desarrollo facial, alcanzando con esta alternativa resultados estéticos muy satisfactorios a lo largo de los años.  Se colectaron en Quito - Ecuador datos de 36 pacientes que habían finalizado sus tratamientos mediante mecánica de cierre de espacios. 19 hombres y 17 mujeres entre adolescentes y adultos, se autoevaluaron a través de una encuesta. Las variables a considerar fueron: edad, sexo, nivel de satisfacción, tiempo transcurrido desde la finalización del tratamiento, y si se realizaron tratamientos estéticos adicionales. Los test de hipótesis muestran que el 65% está muy satisfecho con los resultados obtenidos, el 44% terminó su tratamiento hace más de 3 años, y que el 67% no se realizó ningún tratamiento adicional. Se concluye por tanto que esta mecánica es altamente satisfactoria en esta muestra.

An Investigation on the Preference Approach in Experiencing Open and Distance Learning Methods
Authors: Binti Md Nujid Masyitah , Ain Tholibon Duratul
Published: August 2021

Open and distance learning (ODL) has become an alternative in teaching and learning (T&L) while the COVID-19 pandemic crisis struck the world globally in December 2019. However, the preferred tool and platform to be chosen in the transition period among students remain uncertain. The purpose of this study was to assess and investigate the effect of T&L preference techniques and technologies chosen by employing ODL in universities during the pandemic. This research adopted a descriptive approach and a quantitative survey was used to collect the necessary data. The questionnaire consisted of 14 questions and was separated into two parts: demographic information and undergraduate students' preference towards online class technology during the COVID-19 pandemic. Four themes and 16 sub-themes were identified in the set of questions in the survey. The results of the analysis revealed that ODL is the preferred method with WhatsApp social media platform as the medium for communication between educators and learners. Educators might consider devoting additional attention to improving teaching and learning practices in open and distance learning in choosing the right approaches and platform to be used through online and offline classes.
How Can You See in the Dark Part II Mapping
Authors: Francis Sherese
Published: August 2021

Part of my current Blue(s)Print poetic practice, this piece was written after attending a friend's Nichiren Buddhism conference and then later attending Betty’s Daughter Arts Collaborative’s black/water: The Digital Ceremony. The shape of the poem's maps are inspired by the Angaria Delphinus shell I received recently, thinking about the connections to the Delphi Oracles, Sibyls, and Mami Wata priestesses. I want this piece to represent the Sux within language and history, and that language can be a meditative, spiritual guide and gate opener to the vast history and connections of the diaspora. Is what we think of as lost really lost or just transformed and in constant motion?
Waterbearer: A Reading From the Book of...
Authors: Collier-Mercado Constance
Published: August 2021

In the following piece, I examine the relationship between color and water (Baby Suggs and Beloved) in Toni Morrison's novel, Beloved, as a type of synesthetic coping mechanism meant to disrupt the encroaching normalization of an anti-Black world postslavery.

Early in the text I posit two questions:
What if Baby Suggs’ appetites shifted, not as some kind of woeful trauma response but as a very deliberate solution to the problem of a world where everyone else’s senses lie askew?

What if Beloved likewise rose up from the water, not as a vengeful haunting but a haintful reminder for those living who had lost their way?

Building upon this theory, I expand its reach to establish a continued relationship to water and the sensory which Black people have inherited today as our own surreal legacy - one which requires a constant mental reorientation toward freedom. In constructing my thesis, I reference Beloved but also several other critical works of Uction, nonUction, poetry, visual art, Ulm, and sound, each framed as meditation on a particular color and liturgical text ("a reading from the book of... ") to create a mixed media ekphrasis that mimics the surreal in both citation and physical form. The Unished product can be described, at its simplest, as a braided creative nonUction essay or, at its most complex, as a hybrid blend of cultural commentary, personal essay, poetry, and scholarly article.

LOS INFORMES DE EVALUACIÓN DE IMPACTO DE GÉNERO (IEIG) COMO GARANTÍA DEL GENDER MAINSTREAMING Y SU INCIDENCIA EN LA NORMATIVA Y JURISPRUDENCIA ESPAÑOLA
Authors: GIL RUIZ JUANA MARÍA
Published: August 2021

Este trabajo parte de la obligada y necesaria incorporación de la
perspectiva de género como corriente principal (gender mainstreaming) en el ordenamiento
jurídico y político, como exigen los compromisos internacionales y europeos.
En este sentido, se repara en los Informes de Evaluación del Impacto de Género,
y en su incidencia en la normativa y jurisprudencia española, en tanto que se
consideran legalmente instrumentos básicos de la política de igualdad inter-géneros.
El análisis de la jurisprudencia contencioso-administrativa de los Tribunales pluripersonales
respecto a su fiscalización constata que su teórica efectividad es más
que decepcionante, y que se legitima, a través de un procedimiento vacuo de perspectiva
de género, la adopción de medidas legislativas, administrativas y/o políticas
que perpetuarán la discriminación aunque travestida, ahora, de transversalidad.

Lan honen nahitaezko eta behar-beharrezko abiapuntua da generoaren
ikuspegia ildo nagusitzat sartzea ordenamendu juridiko eta politikoan
(gender mainstreaming), nazioarteko konpromisoek eta europar konpromisoek
eskatzen duten moduan. Alde horretatik, genero-eraginaren ebaluazioari buruzko
txostenak hartzen dira aztergai, bai eta txosten horiek Espainiako araudian eta jurisprudentzian
izan duten eragina ere, generoen arteko berdintasunerako politiken
oinarrizko tresnatzat jotzen baitituzte legeek. Kide anitzeko auzitegiek administrazioarekiko
auzien arloan emandako jurisprudentzia analizatuz gero, egiaztatuko
dugu zein etsigarria den txosten horien eraginkortasun teorikoa, eta, gainera, nola
legitimatzen duten, genero ikuspegirik gabeko prozedura baten bitartez, diskriminazioa
iraunarazten duten neurriak ezartzea legegintzaren, administrazioaren eta/
edo politikaren arloetan, nahiz eta zeharkakotasunaren itxurapean izan.

This paper originates from the required and necessary
incorporation of the gender perspective into the judicial and political systems
(gender mainstreaming), as stated in international and European commitments. In
this sense, existing gender impact assessment reports are taken into consideration
as well as their implications on the Spanish legal system and jurisprudence, insofar
as they are legally regarded as basic instruments for the development of intergender
equality policies. An analysis of the administrative litigation jurisprudence
of the pluripersonal courts shows that its effectiveness in theory is more than
disappointing. Moreover, it legitimises, through a procedure empty of gender
perspective, the adoption of legislative, administrative and/or political measures
which perpetuate the discrimination, whilst disguised as being gender transversal.

erosketa publiko berritzailea.

This work studies the innovative public purchase as an expression
of how public administrations pledge to innovation as a key element for
their competitiveness, efficacy and efficiency and for guaranteeing the provision
of more sustainable and of a greater quality public services, which allow a deeper
involvement by the public sector when implementing policies regarding the Research,
Development and Innovation. This analysis starts from considering the innovative
public purchase as a new tool that comes to complete and complement
to those techniques for boosting and promoting the innovation as granting public
subsidies, setting fiscal incentives, access to new sources of funding and the development
of joint technological initiatives between the public and private sector.
EL DERECHO A LA CONSULTA DE LOS PUEBLOS INDÍGENAS. NATURALEZA, ELEMENTOS Y PROCEDIMIENTOS PARA SU APLICACIÓN EN EL ESTADO
Authors: MARTÍNEZ DE BRINGAS ASIER
Published: August 2021

El siguiente texto propone hacer un acercamiento a la naturaleza
normativa de la consulta, teniendo en cuenta las características con la que
la misma se expresa, tratando de delimitar su contenido, de dar expresión a algunos
de sus elementos problemáticos, conflictivos, cuyos límites y dimensiones
no han sido todavía expresados ni atendidos con suficiente rigor normativo.
También trataremos de desarrollar un procedimiento para la comprensión, sistematización
y aplicación de la Consulta en diferentes contextos; de dar medida de
cada uno de los elementos que la componen, llamando la atención sobre la complejidad
intrínseca que los mismos encierran debido al grado de abstracción con
el que han sido recogidos en algunos textos normativos, así como por la multiplicidad
y complejidad de los actores en conflicto que implican.

Testu honen asmoa kontsultaren arau-izaerara hurbilketa bat
egitea da, eta, horretarako, kontsultaren ezaugarriak hartzen ditu kontuan, kontsultaren
edukia zedarritzen saiatzen da, eta alderdi arazotsu eta gatazkatsuenak
azaltzen, kontsultaren mugak eta dimentsioak ez baitira oraindik arauetan behar
besteko zehaztasunez azaldu eta aztertu. Halaber, kontsulta testuinguru desberdinetan
ulertzeko, sistematizatzeko eta aplikatzeko prozedura bat lantzen eta
konsultaren elementu bakoitza azaltzen saiatuko gara. Elementu horien berezko
konplexutasuna nabarmenduko dugu, kontuan izanik arau-testu batzuetan duten
abstrakzio-maila eta gatazkan dauden aktoreen aniztasuna eta konplexutasuna.

The following text proposes to make an approach to the normative
nature of the consultation, taking into account the characteristics with which
it is expressed, trying to define its content, to give expression to some of the
problematic elements, conflicting, the boundaries and dimensions have not yet
been addressed with sufficiently rigor. Also try to develop a process for understanding,
systematization and application of the Consultation in different contexts
as to give each of the elements that compose it, drawing attention to the
inherent complexity that they contain because of the degree of abstraction which
have been collected in some legal texts well as the multiplicity and complexity of
actors involved in conflict.
Az EU–Mercosur és az EU–Vietnám szabadkereskedelmi egyezmények magyar hatása
Authors: Kutasi Gábor
Published: August 2021

Az EU szabadkereskedelmi megállapodást kötött Vietnámmal és a Mercosur integrációval. Az EU egészére is minimális növekedési hatást gyakorol, míg a magyar gazdaságra ennyi sem várható, hiszen utóbbi esetében a két kereskedelmi térség súlya ezrelékben mérhető. Mégis, túlmutatva a közvetlen GDP hatásokon, lehetősége van Magyarországnak pozitív összegű kimenetet kialakítani az egyezményekből. Az elemzés a két térséggel folytatott kereskedelem strukturális elemzésén keresztül rámutat a versenyképességi előnyökre, az iparágon belüli kereskedelem elemzésével pedig feltárja a globális értékláncokba való integráltság elmélyítésének lehetőségét az egyezményeken keresztül. A kereskedelmi egyezmények növekedési hatását felmérő empirikus irodalomelemzésen keresztül beazonosításra kerülnek az a magyar ágazatok, amelyek esetében a kölcsönös kereskedelmi forgalom bővíthető. Mindezek alapján megfogalmazható, hogy mit tud tenni a kereskedelempolitika a két egyezményben rejlő lehetőségek kiaknázására.

Para os alunos com transtornos globais do desenvolvimento a educação Inclusiva se torna um grande desafio da sociedade. Se desenvolvendo na década de 70, a educação inclusiva abrange muito além da pessoa com deficiência envolve muito mais que a pessoa com deficiência, gira em torno da família, da escola e a sociedade. Por seguinte, este ponto do que se refere o estudo: a inclusão de alunos com deficiência na classe regular. Com esta investigação, procura-se avaliar as situações interativas que estes educandos firma com seus docentes e colegas nas salas de aula do ensino regular. Sendo assim, se viabiliza avaliar como se dá a introdução desses alunos no que se refere da classe convencional, quando no tocante a maior parte dos alunos, sequer apresenta tais necessidades especiais. O estudo no geral fica orientado para a reflexão dessas condições que atuam no fato de não existir uma uniformidade na forma de ensinar, com resultado para a expressão de ideias abrindo um diálogo original, notoriamente porque escola/professores não estão preparados para atender este público.

The objective of this paper is to presents new design on assistive smart glasses for visually impaired. The objective is to assist in multiple daily tasks using the advantage of wearable design format. The proposed method is a camera based assistive text reading to help to blind in person in reading the text present on the text labels, printed notes and products in their own respective languages. It combines the concept of Optical Character Recognition (OCR), text to Speech Synthesizer (TTS) and translator in Raspberry pi. Optical character recognition (OCR) is the identification of printed characters using photoelectric devices and computer software. It converts images of typed, handwritten or printed text into machine encoded text from scanned document or from subtitle text superimposed on an image. Text-to-Speech conversion is a method that scans and reads any language letters and numbers that are in the image using OCR technique and then translates it into any desired language and at last it gives audio output of the translated text. The audio output is heard through the raspberry pi's audio jack using speakers or earphones.

The main aim of our work is to achieve low power, high speed design goals. The proposed hybrid adder is designed to meet the requirements of high output swing and minimum power. Performance of hybrid FA in terms of delay, power, and driving capability is largely dependent on the performance of XOR-XNOR circuit. In hybrid FAs maximum power is consumed by XOR-XNOR circuit. In this paper 10T XOR-XNOR is proposed, which provide good driving capabilities and full swing output simultaneously without using any external inverter. The performance of the proposed circuit is measured by simulating it in cadence virtuoso environment using 90-nm CMOS technology. This circuit outperforms its counterparts showing power delay product is reduced than that of available XOR-XNOR modules. Four different full adder designs are proposed utilizing 10T XOR-XNOR, sum and carry modules. The proposed FAs provide improvement in terms of PDP than that of other architectures. To evaluate the performance of proposed full adder circuit, we embedded it in a 4-bit and 8-bit cascaded full adder. Among all FAs two of the proposed FAs provide the best performance for a higher number of bits.

Objectives: Hepatitis B virus (HBV) is a major public health problem worldwide. The prevalence of HBV is dependent on the modes of transmission. Chronic hepatitis B (CHB) infection can progress to liver cirrhosis and hepatocellular carcinoma. Oman is regarded as an intermediate endemic region and has had a neonatal vaccine against HBV since 1990. However, little research has been conducted regarding risk factors for HBV transmission. Our study aimed to identify the prevalence of major risk factors for acquiring HBV in Oman. Methods: We conducted a retrospective chart review of all adult Omani patients diagnosed with CHB at two tertiary hospitals in Oman, Sultan Qaboos University Hospital and Armed Forces Hospital, between February 2009 and July 2013. The prevalence of major risk factors was identified by interviewing CHB patients using a standard questionnaire during their follow-up visits to the hepatology clinic at both hospitals. The risk factor frequency was stratified by age, gender, and educational level. Results: A total of 274 patients were interviewed; 52.2% of the participants were males. The median age for men was 35.9 years and 35.1 years for women, with 75.5% aged 20–39 years old. The antenatal screening was the most common means of identifying HBV infection in females, and pre-blood donation screening was the most common in males. Intra-familial contact with HBV infected persons and behavioral risks such as body piercing (females) and barber shaving (males) were more common than nosocomial risk factors. Knowledge about HBV infection was scarce among our participants. More than half of the participants had a positive family history of HBV infection. There was a significant association between HBV infection and age groups, and educational levels (p < 0.050 and p < 0.001, respectively). Among those who were infected due to intrafamilial contact or behavioral risk, there was a significant difference between the two sexes (p < 0.020) and between the three age groups (< 23, 23–28, >28) of HBV positive mothers (33.3%, 14.3%, and 6.6%, respectively; p < 0.050). There was also a statistically significant difference among different educational levels (p < 0.050). Conclusions: Direct contact of infected individuals within a family and exposure to high-risk behaviors such as piercing and barber shaving are the main reported risk factors for HBV infection in Omani patients. Reducing the vertical and horizontal transmission of HBV in Oman could be improved by implementing routine antenatal screening of pregnant women and a greater focus on contact screening, respectively.
Proposições para um Método Fenomenológico Hermenêutico para a Pesquisa de Campo
Authors: Frota Ana Maria Monte Coelho , Dutra Elza Maria Socorro
Published: August 2021

Este artigo trata de reflexões acerca da construção de um método de pesquisa em psicologia inspirado na filosofia de Martin Heidegger. Para tanto, inicia discutindo sobre a fenomenologia. Em seguida, debruça-se sobre Heidegger, discutindo brevemente alguns elementos de sua ontologia, sempre no sentido de aproximação de um caminho possível de pesquisa fenomenológica que se oriente nessa direção. Finalmente, apresenta o círculo hermenêutico, tal qual proposto por Heidegger, sugerindo possíveis caminhos de pesquisa fenomenológica com inspiração heideggeriana. Mais do que apresentar um modelo de pesquisa, procura abrir discussões geradoras de novas reflexões.
