Published: December 2021

Learning is a process of student interaction with teachers and learning resources in a learning environment. The article clearly states that learning is a process of interaction between teachers (educators) and students (students). During this pandemic, all learning processes are carried out remotely. Because face-to-face learning in class cannot be carried out as a result of the highly contagious corona virus outbreak. The selection of the right learning media must pay attention to and adjust the needs of the subject matter so that the media functions as a tool that can increase understanding and interest in learning. Zooming presentation learning media is one of the newest applications that has a fresh, unique, attractive appearance and has sophistication in zooming in and out and can combine videos, images and animations. With this community service, it is hoped that it can help the problems of teachers at Darul Faizin High School regarding online learning problems. So that this socialization can be a solution in providing learning materials to students.

Published: December 2021

Electricity is needed by the community because it is easily converted into other forms of energy. Electricity is very useful but at the same time dangerous for humans if they do not have the knowledge, understanding and skills about it. This training was carried out with the aim of providing knowledge about electrical hazards and skills in electrical installation for residents of RW 15, Ciwaruga Village, Parongpong District. With the materials and methods and approaches applied, the training can run smoothly and work well. This success is shown by the active participation and high enthusiasm of the participants during the training and the high level of absorption of the training materials delivered. This is reflected in the increase in knowledge and skills in terms of making good installations as indicated by the increase in the value of the final test results (posttest). In addition, this paper can also be used as a reference for parties who will carry out similar or other activities related to electrical installations.
Analysis of the dynamics of IPO transactions in the banking sector
Authors: Belyaev V. A.
Published: December 2021

IPO (initial public offering) is a widespread financing instrument in the world, however, the scientific community pays little attention to the dynamics of IPOs in the banking sector. Theaimof the study is to critically analyze the dynamics of IPO transactions of credit institutions on the horizon from January 1, 2000, to December 31, 2020. The researchmethodologyincludes analytical methods for collecting and processing information, comparative and graphical analysis of the database collected by the author and consisting of 305 IPOs of banks from 2000 to 2020. The study compares the dynamics of IPO transactions of credit institutions from developed and developing countries, identifies characteristics inherent in each market, and explains the differences in market dynamics. The study reveals clustering in the IPO market of credit institutions and compares clustering with the general market of initial public offerings. It is shown that lending institutions around the world have actively attracted funds through IPO, having placed their shares for a total of $ 218 billion. The bulk of the funds were attracted by banks from emerging markets, primarily from China. During this period, there were 3 IPO waves on the banking IPO market, characterized by a significant increase in placement volumes and profitability on the first day of trading. This clustering in the IPO market of credit institutions was not typical only for the banking sector but coincided with the global growth in the number of transactions and IPO yields. The authorconcludesthat the placement of shares of credit institutions during the hot market period is the most promising in terms of the volume and dynamics of raising funds; the IPO market of credit institutions retains high growth potential, primarily in Asia and the CIS.
New risk measures for variance distortion and catastrophic financial risk measures
Authors: Minasyan V. B.
Published: December 2021

In recent years, expectation distortion risk measures have been widely used in financial and insurance applications due to their attractive properties. The author introduced two new classes of financial risk measures “VaR raised to the power of t” and “ES raised to the power of t” in his works and also investigated the issue of the belonging of these risk measures to the class of risk measures of expectation distortion, and described the corresponding distortion functions. The aim of this study is to introduce a new concept of variance distortion risk measures, which opens up a significant area for investigating the properties of these risk measures that may be useful in applications. The paper proposes a method of finding new variance distortion risk measures that can be used to acquire risk measures with special properties. As a result of the study, it was found that the class of risk measures of variance distortion includes risk measures that are in a certain way related to “VaR raised to the power of t” and “ES raised to the power of t” measures. The article describes the composite method for constructing new variance distortion functions and corresponding distortion risk measures. This method is used to build a large set of examples of variance distortion risk measures that can be used in assessing certain financial risks of a catastrophic nature. The author concludes that the study of the variance distortion risk measures introduced in this paper can be used both for the development of theoretical risk management methods and in the practice of business risk management in assessing unlikely risks of high catastrophe.

Authors: Ataniyazov J. X. , Shirinova S. S.
Published: December 2021

This article examines the conditions for the formation of financial and industrial groups in Uzbekistan and the participation of commercial banks in their activities. The purpose of the study is to formulate recommendations for creating the necessary conditions for the formation and organization of the activities of financial and industrial groups. The authors used the following research methods: grouping, abstraction, comparative analysis, structural analysis, and scientific forecasting. This article also describes the role of financial and industrial groups in the development of the economy and assesses the possibility of creating financial and industrial groups with the participation of commercial banks. In addition, the features and prospects for the creation of financial and industrial groups in Uzbekistan have been identified. The authors conclude that there are the following grounds for the formation of financial and industrial groups with the participation of commercial banks in Uzbekistan: the volume of commercial bank loans allocated to the real sector of the economy is increasing, there is a great need for financial resources to modernize production, as well as technical and technological re-equipment of enterprises. The formation of financial and industrial groups in the national economy will lead to the sustainable development of the industrial sector, ensuring the stability of the financial and banking system and increasing the competitiveness of the national economy.
Priority development areas as a tool for enterprises support in Russian monotowns
Authors: Beleva S. G. , Veterinarov V. V. , Kozlyakov G. S. , Suchkova O. V.
Published: December 2021

This paper aims to estimate the effectiveness of the Priority Development Areas (PDA) program in Russian monotowns at the firm level. Using data from the SPARK-Interfax database on Russian companies in 2014–2018, the authors estimate the effect of the PDA residency on the firms’ revenue growth in monotowns in Russia. The authors test two hypotheses. First, the status of the PDA resident is obtained by firms that have been successful in previous periods. Second, the PDA resident status does not have a positive effect on firm growth. To measure the treatment effect, the authors use the nearest neighbor propensity score matching method, which allows drawing conclusions about causality, as opposed to the ordinary least squares (OLS) method. The regressions consider the firm size, industry, and geographic location of the city. According to the results of the study, both hypotheses are confirmed. Resident status is determined by the gains in the company’s revenue for the two previous periods (the coefficients are significant in all specifications at the 5% level). The influence of residency on the firm’s revenue growth is neglected (becomes insignificant) when comparing enterprises with the same pre-2015 trends. Thus, the authors conclude that the success of the PDA program in Russian monotowns in terms of business support is questionable. The findings of the study are valid for enterprises established before 2015.
From X to Y: Anatomy of a Constructional Pattern
Authors: Valenzuela Javier
Published: December 2021

Compositionality is undoubtedly one of the hardest problems in linguistics. In decoding theories, the speaker occupies a leading role, having to carefully choose the form that better encodes the meaning to be communicated. In contrast, in inferential theories, the burden is shifted from speaker to hearer: linguistic information typically underspecifies meaning and the hearer must make a number of inferences to bridge the gap between what is said and what is meant. In this article, I argue that constructional meaning can aid the process of sentence meaning formation by providing a scaffold that can help the hearer with the construal operations. Constructions, by providing an additional layer of meaning, constrain the range of possible meanings activated by words thereby reducing the combinatorial explosion when several words are joined together. This process is examined here by analysing the meanings associated with the grammatical construction [from X to Y], which is connected to a polysemy network of related senses, using examples extracted from a multimodal corpus. A preliminary analysis of the gesturing behaviour associated with the different senses proposed is also included, which can be seen to contribute to the characterisation of the different senses of the polysemy network.
A Comparison of Two Genres: Lexical Bundles in the Discourse of Applied Linguistics
Authors: Gholaminejad Razieh
Published: December 2021

The present article is a corpus-based descriptive/comparative study of lexical bundles (LBs) in two university genres: textbooks (TBs) and research articles (RAs) on applied linguistics. It aims to identify the LBs used in the two genres, compare them on the basis of their functional type and frequency and explore how they are related to genre. To this end, four-word LBs were identified in two corpora drawn from applied linguistics TBs and RAs. The comparative analysis revealed that there are interesting differences between the two genres in terms of discourse functions: the occurrence of LBs in the TBs was lower than in the RAs; attitudinal/modality LBs occurred more frequently in the TBs than in the RAs; epistemic LBs occurred more frequently in the RAs than in the TBs; discourse organizers occurred more frequently in the RAs than in the TBs; and time, place and text reference LBs occurred almost twice as frequently in the RAs. The findings build on research into the variations of genres in terms of the use and functions of LBs in discipline-specific corpora.
The Double-Headed Arrow of Trauma: The Morally Traumatised Perpetrator in Martin Amis’s Time’s Arrow
Authors: Roldán-Sevillano Laura
Published: December 2021

Martin Amis’s Time’s Arrow (1991) gave rise to much controversy when it came out, for this novella revolves around a traumatised Nazi doctor exiled in the US whose life is narrated in a disorienting reverse chronology by what would seem to be his own dissociated conscience. Despite the abundant academic publications on this experimental narrative, such as those that read it as a posttraumatic stress disorder (PTSD) piece of fiction, the origin of the protagonist’s damaged psyche and the diverse symptoms he suffers from have not yet been explored from the viewpoint of perpetrator trauma, a moral-related syndrome distinct from PTSD that affects victimisers haunted by remorse. Drawing on trauma theory and the recently developed concepts of perpetration-induced traumatic stress (PITS) and moral injury, this article aims to contribute to the scholarly conversation on Amis’s novella by arguing that its narrative voice, backwards temporality, intertextuality and recurrent motifs perform the perpetrator/protagonist’s moral-based trauma provoked by an acute sense of shameful guilt and the fear of being discovered. The article concludes by suggesting that, through this staggering work, Amis gives readers not only an opportunity to actively remember and reflect on the Nazi genocide but also an insight into trauma from an unusual but necessary perspective.
"You": A Girl amidst Images and Sounds of Adult Violence in Joyce Carol Oates’s Rape: A Love Story
Authors: Cortés Vieco Francisco José
Published: December 2021

Teena Maguire and her child, Bethie, are brutally attacked and beaten by a mob of violent young men in a park at night. While the mother is gang raped and nearly killed, the daughter is both the witness and the victim of physical and psychological violence. Through its innovative second-person narration, Joyce Carol Oates’s novella Rape: A Love Story (2004) contributes to her sustained interest in family relationships, violence, crime and justice. However, rather than focusing on the victim of the rape, Oates writes a coming-of-age story that explores the daughter’s trauma, posttraumatic stress disorder and fight for survival, a struggle that coincides with the girl’s critical passage from childhood to adulthood. During the months after the assault, Bethie’s innocence is also repeatedly violated by the aggressors’ intrusion into her life and the hostility of the community in the town of Niagara Falls and its social institutions, such as police, school, media, healthcare and the judicial system. Unable to cling to girlhood or to find maternal protection, her forced witnessing of her mother’s gang rape compels Bethie to mature too early while experiencing her first love for a man.

Published: December 2021

Web analytics technologies provide opportunities for organisations to obtain information about users visiting their websites in order to understand and optimise web usage. Use of such technologies often leads to issues related to data privacy and potential lock-in to specific suppliers and proprietary technologies. Use of open source software (OSS) for web analytics can create conditions for avoiding issues related to data privacy and lock-in, and thereby provides opportunities for a long-term sustainable solution for organisations both in the public and private sectors. The paper characterises use of and engagement with OSS projects for web analytics. Specifically, we contribute a characterisation of use of OSS licensed web analytics technologies in Swedish government authorities, and a characterisation of organisational engagement with the Matomo OSS project for web analytics.
Teaching and learning during the Covid-19 pandemic: University students’ perspective on phase 3
Authors: Zucchermaglio Cristina , Alby Francesca , Marino Filomena
Published: December 2021

Whereas there is a growing body of research focusing on the university educational activities during the first phase of the Covid-19 pandemic that started abruptly in the spring 2020, the next phase (August-December 2020) is still quite under-studied. Throughout this phase, Sapienza, as many other Italian universities, implemented a teaching approach by combining in-person and remote attendance for many of the lessons. As a result of this arrangement, a quote of students (with the professor) was physically in the classroom, whereas the other students were connected in streaming. The present work explores the students’ perspective on benefits and problems of such a new technological choreography and educational arrangement. Their suggestions may contribute to plan new post-pandemic blended scenarios.
The Treatises Named after the Prophet Muhammad ("Great Manshur and "Little Manshur") in Medieval Armenian Bibliography
Authors: Mkrtumyan Gayane
Published: December 2021

The present article discusses the treaties known in the Armenian medieval bibliography by the name of the Prophet Mohammad ("Great" Manshur and "Little Manshur”). It is pointed out that the above-mentioned treaties were given to the Armenians during the Arab invasions in Armenia at the end of the 7th century and at the beginning of the 8th century, but they are considered in the context of the tradition of different treaties named after the Prophet Muhammad given to the Armenians and other Christian nations. In the following centuries, the terms of the above-mentioned treaties were laid down as a basis in similar covenants in the name of the Prophet Muhammad, with the new privilege - expecting the Muslim authorities to protect their rights from possible encroachments.
İHVÂN-I SAFÂ’NIN BİLGİ ANLAYIŞININ DİN EĞİTİMİ ALANINDAKİ İZDÜŞÜMLERİ
Authors: GEÇİOĞLU Şeyma , YÜRÜK Tuğrul
Published: December 2021

İnsan, kendini tanımaya ve kendi dışındaki varlıkları bilmeye çabalayan bir varlık türü olarak, bilgiye konu olan önce kendisi ve kendi türü ile ve daha sonra da kendi dışındaki nesnelerle değişik şekillerde ilişkiye girerek farklı bilgiler edinmektedir. Bu nedenle bilgi konusu insanın var oluşundan bu yana önemini korumakta, bilginin kaynağı, oluşumu, hakikati vb. meseleler çoğu düşünürün ilgisini çekmektedir.
Bilgiye, insana ve evrene ilişkin değerlendirmelere belirli dönemlerde belirli bakış açıları egemen olmaktadır. Toplumda egemen olan “inanç ve değerler” değiştiğinde insanın evrene, bilgiye bakış açısı da değişmektedir ve yeni paradigmalar ortaya çıkmaktadır. Bu paradigmalar da aynı şekilde bilimsel alanda yapılan çalışmaları etkilemekte ve her bilimsel disiplinin kendi yapısına göre bir bilgi anlayışı, diğer adıyla bir epistemolojisi var olmaktadır. Genelde Eğitim, özelde Din Eğitimi de bunlar arasındadır. Epistemoloji, Din Eğitimi Biliminin en önemli boyutlarından birini oluşturur. Çünkü eğitimin öğrenme ile öğrenmenin ise bilgi ile şekillendiği, bu ilişkinin sonunda ise öğrenen bireyin bilgi edindiği söylenebilir. Bu noktada bilgiye yaklaşımın din eğitimi anlayışlarına yansımaları, araştırılması gereken bir konu olarak ortaya çıkmaktadır.
Her toplumda bilginin, kültürün ve değerlerin oluşmasına katkıda bulunan insanlar veya topluluklar bulunduğu ve onların toplumun düşünce hayatını şekillendirip düzenlediği söylenebilir. Eğitim faaliyetleri de oluşan bu yapının üretilmesi ve bir sonraki nesle aktarılmasında önemli bir araç olarak işlev görür. Bu anlamda İhvân-ı Safâ da İslam toplumunda ortaya çıkan bilginin üretilmesi ve bir sonraki nesle aktarılmasında rol oynayan önemli bir gruptur. Bu bağlamdan hareketle bu çalışmanın konusu bilgi anlayışının eğitim ve din eğitimi alanına etkisini İhvân-ı Safâ’da bunun nasıl tezahür ettiği örneğinden hareketle incelemektir. Böylece bilgi anlayışının farklılaşmasının din eğitimine etkisi ortaya konulmaya çalışılacaktır. Bu çerçevede öncelikle bilgi olgusu ele alınmış ve bilginin Nesnelci ve Yapılandırmacı yaklaşımlar özelinde eğitime/din eğitimine etkisi incelenmiştir. Buradan hareketle bilgi hakkındaki farklı yaklaşımların eğitimi-öğretimi şekillendirdiği görülmüştür. Daha sonra İhvân-ı Safâ’nın bilgi anlayışı üzerinde durulmuş ve bu anlayış çerçevesinde yaptıkları eğitim/din eğitimi, Nesnelci ve Yapılandırmacı yaklaşımlar bağlamında değerlendirilmiştir. Buna göre İhvân-ı Safâ’nın felsefesinde insanın merkezde olduğu, bilgi konusunda eklektik bir yapıya sahip oldukları, bilgi kaynaklarını duyu, akıl, burhan, vahiy ve ilham olarak kabul ettikleri tespit edilmiştir. İhvân-ı Safâ’nın eğitim felsefesine öğrenme ve öğretme durumları açısından bakıldığında hem Nesnelci hem de Yapılandırmacı niteliklerle benzerliklere sahip olduğu, bununla birlikte Nesnelci yaklaşımla olan benzerliklerin daha ağır bastığı tespit edilmiştir. Son kısımda ise çıkarılan sonuçlardan faydalanılarak birtakım önerilerde bulunulmuştur.

Authors: Lie Carrissa Shannon , Pranata Yohanes Kristian
Published: December 2021

This research to understand management Right which defined in the Government Regulation No. 18 of 2021 Article 1 No. 3 as the State’s ownership right in which a part of the authorization is given to the Management Right holder. The type of research was juridical normative law research, which was a research that emphasizes in written documents as the main law resources, such as regulations, court decisions, law theories, and scholar’s opinions. There were 2 (two) approaches used to support this research. The first one was statute approach, which was done by analyzing all the related regulations and others that were related to currently law issues. One of the authorities that the holder has is to hand in parts of the Management Right land to a third party and/or cooperating with a third party. If the land is used by a third party, then a Land Right has to be given on the land for the third party’s basis to utilize and/or use the land. The handing of Land Rights to a third party must be done with the holder’s agreement. Therefore, the third party uses the land with the right on a certain land that is initiated on the Management Right land. The main issue that will be discussed is what types of land rights that can be given on the lands. This research is a law research with a normative law research method. Besides that, this research uses statute approach and conceptual approach. The conclusion is the land rights that can be given on the land are Building Rights on Land and Land Use Rights.

Published: December 2021

Objective: First tarsometatarsal joint (TMTJ) arthrodesis, also known as Lapidus, is a surgical procedure used to treat severe hallux valgus, associated hypermobility of the first ray, and/or osteoarthritis of the first TMTJ. Despite the high satisfaction rate and high corrective power, this technique is not without complications. This study aimed to report the complications of first TMTJ arthrodesis. Methods: This is a case series of 16 patients treated with first TMTJ arthrodesis. Patients were evaluated based on foot radiographs, clinical alignment of the hallux, and signs and symptoms. Results: Eight patients had either major or minor complications. Three patients had recurrent deformity (1 with associated nonunion), 2 had delayed union, 2 had hardware loosening (1 with associated nonunion), and 1 had wound dehiscence. Conclusion: First TMTJ arthrodesis requires greater care in choosing the surgical technique for the treatment of hallux valgus. In addition, some points should be considered to minimize complications as much as possible. We believe that data are still scarce to provide a concrete basis.

Concept, etiology, and pathomechanics of hallux rigidus
Authors: Monteagudo de la Rosa Manuel , Viladot-Pericé Ramón
Published: December 2021

There is a continuous anatomical, functional and pathomechanical roadmap from functional hallux limitus to hallux rigidus. Although many etiologies for hallux rigidus have been studied it is very probable that it has a primary origin with less-than-ideal movement when we are born. Upon a restricted range of motion, symptoms may arise depending on the amount of work and how compensatory mechanisms work around the first metatarsophalangeal joint. Changes occurring at the joint that allow the transition from a sliding movement mechanism (physiological) to a rolling mechanism (pathological) may trigger anatomical and functional changes resulting in pain and dysfunction. Any surgical technique that is able to restore the sliding mechanism to the first metatarsophalangeal joint will have a positive impact on pain and function in a patient with a symptomatic functional hallux limitus/rigidus.

One versus two adjacent interdigital neuroma excision: a patient outcome study
Authors: Benjamin Kefilwe Boineelo , Saragas Nikiforos , Ferrão Paulo
Published: December 2021

Objective: We aimed to evaluate patient satisfaction after surgery for both single and two adjacent neuromas. Methods: We reviewed the data of patients treated operatively for interdigital neuromas between 2003 and 2016. We interviewed them and administered the Self-Reported Foot and Ankle Score questionnaire. Patient scores were then analyzed categorically, and variation between groups was assessed. Results: Sixty-two patients were available for review. Thirty-one patients had a single interdigital neuroma excised and 31 had two adjacente interdigital neuromas excised. Twenty-eight of the 31 (90%) patients with a single neuroma had good or excellent results while 23 (74.2%) of those with adjacent neuromas had similar outcomes. One patient with a single neuroma had a poor result while four patients with adjacent neuromas had poor results. The mean score was 41 (excellent) for patients with a single interdigital neuroma and 37 (good) for those with adjacent neuromas (p=0.473). The majority of patients in both groups would undergo surgery again. Conclusion: We found no statistically significant difference in outcomes of patients who undergo surgery for either single or two adjacent interdigital neuromas. General patient satisfaction is good and/or excellent post excision. Level of Evidence II; Prognostic Studies; Retrospective Study.

Published: December 2021

Introduction: Hallux rigidus (HR) is a frequent pathological condition of the foot, responsible for marked functional impairment. Metatarsal-phalangeal arthrodesis is an excellent treatment alternative for advanced stages of the disease, usually performed as an open surgery. Forefoot arthroscopy had its greatest development in the last decade, with a progressive expansion of indications, yielding encouraging results. Objective: To present the clinical and radiographic results of patients undergoing arthroscopic metatarsal-phalangeal arthrodesis of the hallux, depicting the technique and reporting complications. Methods: This study involves a series of cases, we operated 9 patients (10 feet), all with advanced HR (grades 3 and 4 - Coughlin-Shurnas). The patients underwent an arthroscopic procedure through two dorsal portals, small joints instruments. We assessed the results using the AOFAS functional score and the visual analogue pain scale. The radiographic parameters we used to analyze were the metatarsal-phalangeal angulation in the anteroposterior (pre- and postoperative) and lateral (post-operative) views, and we measured the radius shortening. Conclusion: Arthroscopic metatarsal-phalangeal arthrodesis is an excellent treatment option in advanced stages of hallux rigidus, with minimal disruption and providing excellent results, in addition to a low incidence of complications.

Can the European Union’s Market Liberalism Ensure Energy Security in a Time of ‘Economic Nationalism’?
Authors: McGowan Francis
Published: December 2021

The EU’s higher profile in energy policy matters is arguably due to the increased importance of market liberalisation as a policy objective over the last twenty years. Given the EU’s own competences in the internal market and competition policy, the European Commission has accordingly been able to play a more active role in energy policy-making. Moreover it has been active in extending this approach to its energy relations with its neighbours as manifest in the Energy Charter Treaty, the European Energy Community Treaty and bilateral agreements with third countries. The European Commission has been keen to assert the centrality of market liberalisation to its future energy policy and energy diplomacy, notwithstanding the changes that have taken place in energy markets. Given that there appears to be an increased interest in ‘national champions’ amongst both energy exporting countries and at least some EU member states, how far can the EU sustain a strategy of market liberalisation? The article will place current policy dilemmas (and the EU’s role) in the context of a shifting energy policy agenda – essentially from a supply security ‘economic nationalism’ to market liberalism and back again. It then considers how EU policy is adapting to these circumstances and assesses the effectiveness of this response.

O objetivo deste artigo foi descrever as características clínicas e demográficas de pessoas com deficiência atendidas em uma clínica-escola de Odontologia do Nordeste brasileiro, relacionando estes perfis às necessidades acumuladas e aos tratamentos realizados no período de março a julho de 2019. Tratou-se de um estudo de análise de banco de dados no qual foram avaliados os prontuários em relação a sexo, idade, diagnóstico médico, uso de medicamentos, motivo da consulta e tratamentos realizados. Foi utilizada uma amostra de conveniência de 55 prontuários, referentes aos indivíduos em atendimento neste período. Os testes Qui-quadrado e exato de Fisher foram utilizados para verificar associação entre as variáveis estudadas. Foi adotado o intervalo de confiança de 95% e a margem de erro de 5%. Verificou-se que a maioria dos pacientes era do sexo masculino (52,7%) e possuía entre 20 e 59 anos (54,5%). As patologias de base de maior prevalência foram as doenças sistêmicas (34,5%) e deficiência intelectual (32,7%). Em relação às medicações, 80% faziam uso contínuo de algum fármaco. A respeito das consultas odontológicas, a procura de 60% da amostra foi por motivo de dor e os procedimentos mais realizados, os restauradores (63,6%). Além disso, a estabilização física e sedação medicamentosa foram amplamente utilizadas nos pacientes com deficiência intelectual. O atendimento odontológico incluiu pacientes com diversas necessidades especiais e, apesar da clínica-escola em questão priorizar a conduta preventiva, a maior parte dos procedimentos executados foi curativo, podendo estar relacionado com a procura tardia pelo tratamento odontológico e dificuldades de acesso.

Considerando-se a importância e necessidade de um ensino odontológico integrado e da propagação do conhecimento sobre a assistência a pacientes que vivem com o HIV/Aids, o curso de graduação em Odontologia da Universidade de Montes Claros (Unimontes) dispõe de uma disciplina específica para o atendimento desses pacientes, a Clínica Integrada IV. O objetivo deste trabalho é relatar a história e a experiência da disciplina Clínica Integrada IV, desde a sua implantação na grade curricular. A disciplina apresenta como objetivo principal propiciar ao acadêmico o conhecimento multidisciplinar e de um planejamento integral do paciente. O atendimento clínico é realizado a partir de um protocolo idealizado pelos professores e constantemente atualizado conforme a literatura. A avaliação odontológica do paciente com HIV/Aids, na Clínica Integrada IV, inclui a investigação da história de infecções oportunistas, de tendência à hemorragia, presença de doenças cardiovasculares, diabetes e hepatites, uso de medicamentos, além da interpretação de exame de sangue recente. É necessário frisar que as normas de biossegurança do atendimento odontológico são preconizadas igualmente para todos os indivíduos, entretanto ainda há uma estigmatização do tratamento odontológico dos indivíduos com o HIV/Aids. Desta forma, uma disciplina com atendimento a pacientes sabidamente soropositivos oportuniza o acadêmico a ter o contato com esse público durante a sua graduação e a desenvolver o conhecimento necessário para se prestar uma assistência específica e com qualidade.
Estágio curricular supervisionado

O estágio curricular obrigatório desenvolvido pelos cursos de Odontologia é o elemento mais estratégico para a efetivação do Sistema Único de Saúde (SUS) como ordenador da formação de cirurgiões-dentistas. No presente estudo busca-se aprofundar a reflexão sobre a origem das limitações ao desenvolvimento do estágio no SUS e o papel de diferentes instituições e atores nessas dificuldades. Também procura avaliar as limitações e desafios impostos a essa orientação educacional considerando a hegemonia da odontologia de mercado na formação, a qual se expressa no papel pedagógico central atribuído ao procedimento odontológico individual em detrimento do que preconiza a saúde bucal coletiva. Trata-se de ensaio teórico, em que se identificam avanços nessas atividades, obtidos ao se colocar o SUS como campo de estágio essencial para a formação profissional, analisando-os à luz da Constituição Federal, das Diretrizes Curriculares Nacionais dos cursos de graduação em Odontologia e de iniciativas desencadeadas pelos Ministérios da Educação e da Saúde. A análise reconhece o estágio curricular como um elemento potencialmente estruturante do SUS e identifica fatores que o favorecem e que a ele se contrapõem, no próprio SUS, na academia e nos movimentos empresariais. Para isso, deve efetivar parceria com os serviços públicos de saúde, contribuir com o planejamento e gestão de suas atividades, proporcionar formação aos preceptores e pessoal auxiliar envolvidos, além de prover articulação com o controle social. Todos os docentes deveriam ser atores estratégicos dos estágios a partir de sua vinculação de modo permanente a alguma ação ou serviço do SUS, em seus diferentes graus de complexidade, independentemente dos componentes curriculares aos quais está vinculado. Esse desafio transcende os processos tradicionais de formação uma vez que mais do que as estratégias pedagógicas, para essa conquista é mister que o Estado brasileiro, efetivamente, cumpra seu papel no fortalecimento do SUS.

Black gram (Vigna mungo (L.) Hepper) is one of the most important pulse crops in daily diets. However, black gram production and post-harvest preservation are still tedious due to the losses caused by the storage pest bruchine, Callosobruchus maculatus (F.), both quantitatively and qualitatively.   Hence, the present study involves the utilization of the multivariate analysis by effectively understanding variation among the genotypes based on their level of bruchine infestation. The multivariate studies indicated that the traits viz., the total number of adult emergence (AE), seed damage % (SD) and seed weight loss % (SWL) had more variation and with more significant correlation among them.  Also, these traits are the most influential principal component traits governing 88% of the variation among genotypes. The divergence analysis showed that the genotype TU 68 found in cluster II would have the potential to create the variation for bruchine infestation among the black gram genotypes involved in the study.  As it has scored lesser adult emergence (AE) (7 adults), seed damage % (SD) (14 %) and seed weight loss % (SWL) (17.79 %)  than the other genotypes. It shows the resistant nature of the genotype against bruchine beetles. Hence, TU 68 could be utilized in the future hybridization programme as a donor for bruchine resistance.

An invasive pest, fall armyworm, Spodoptera frugiperda (J.E.Smith) (Lepidoptera: Noctuidae) attacks maize at every stage of development, from seedling emergence up to cob formation. Early instar larvae were seen mostly on leaves of maize with characteristics pin or shot hole symptoms. Later instar larvae were confined to deep whorls, leaving typically ragged like appearance and fed on the reproductive stage of the crop especially tassels and developing cobs resulting in quality and quantity loss of maize produce. The effect of commercially available Bacillus thuringiensis subsp. kurstaki product, Dipel® against the second instar larvae of Fall Armyworm (FAW )was not promising under laboratory conditions. Hence, an effort was made to add an adjuvant along with B. thuringiensis to increase the virulence of commercially available B. thuringiensis.The Laboratory bioassays with B. thuringiensis and seven chemical additives ( T1- Bt + Boric acid, T2- Bt + Zinc oxide, T3- Bt + Sodium nitrate, T4- Bt + Peptone, T5- Bt + Urea, T6- Bt + EDTA, T7- Bt + Citric acid & T8-  Bt alone T9- Control) were tested against second instar larvae of Spodoptera frugiperda larvae. The results showed that B. thuringiensis plus sodium nitrate (T3) promoted maximum mortality 82.2 per cent with a minimum LC50 value of 54.620 mg/l. Sodium nitrate boosted B. thuringiensis activity at a concentration of 0.05 per cent by 2.128-fold than B. thuringiensis alone. Overall, sodium nitrate improved the efficacy of B. thuringiensis spray at the maximum level followed by boric acid, urea, EDTA and peptone.

Aedes aegypti management is a global concern due to the absence of medication and effective vaccines. The pesticide-mediated health hazards and rising insecticide resistance in mosquitoes have aggravated the issues. As graphene Oxide (GO)- based nanoformulations are considered a novel mosquito management strategy; the present investigation evaluated the efficacy of GO-based nanoformulations conjugated with malathion (ML) and endosulphan (EN) against Ae. aegypti. The GO was synthesised by Hummers’ method and was confirmed by UV-visible spectral analysis. The GO-ML and GO-EN binary mixtures (1:1 and 1:2) were assayed for toxic potential against mosquito larvae as per WHO protocol and the dead larvae were scrutinized for morphological deformations/abnormalities. The contact irritancy potential of GO nanoformulations was also evaluated against adult Ae. aegypti. The UV-visible spectrum of GO showed a narrow and high peak at ~300 nm corresponding to an n-π* plasmon peak. The GO-insecticide binary mixtures augmented the ML and EN toxicity by 80.43% and 6.43-fold, respectively. The GO-ML mixture-exposed larvae revealed cuticular deposition of black soot while larvae exposed to GO-EN exhibited disintegrated gut viscera. GO-insecticide combinations increased flights in Ae. aegypti denoting irritant potential. The effectual toxic, abrasive and irritant activity of GO-insecticide nanoformulations recommends developing graphene-based toxicants for mosquito management
