Published: December 2021

O objetivo neste trabalho foi avaliar a influência do treinamento e da experiência do examinador no diagnóstico radiográfico de cáries proximais. Para isso, oitenta dentes hígidos ou portadores de lesões cariosas nas faces proximais foram selecionados para a montagem de phantoms, dos quais foram obtidas radiografias interproximais. Estas radiografias foram avaliadas quanto à presença de cáries, por três examinadores. O primeiro examinador realizou duas avaliações: uma antes de iniciar a disciplina de Radiologia, assistindo apenas a uma aula sobre diagnóstico de cáries (treinamento teórico), e outra após seis meses, quando concluiu a disciplina. O segundo examinador avaliou as radiografias apenas após ter cursado a disciplina. O terceiro foi um radiologista. Os dentes foram seccionados e analisados microscopicamente (padrão-ouro). Para cada avaliação foram determinados os índices de sensibilidade, especificidade e acurácia. O teste Kappa foi utilizado para avaliar a concordância intra e interexaminador. Os resultados indicaram que na avaliação inicial do primeiro examinador a sensibilidade foi 0,72 e a especificidade 0,25, indicando um alto número de respostas falso-positivas. Após o curso de Radiologia, os resultados foram semelhantes para os dois alunos. O especialista apresentou os maiores valores de especificidade (0,85) e acurácia (0,69). Os valores Kappa indicaram uma concordância variando de muito leve a moderada. Concluiu-se que a experiência do examinador influenciou no diagnóstico radiográfico da cárie dentária: com o aumento do conhecimento houve uma redução dos resultados falso-negativos e um aumento da acurácia.

O objetivo deste trabalho foi avaliar o potencial das fosfatases ácidas como biomarcadores da resposta tecidual ao implante de osso medular inorgânico bovino. Cápsulas de colágeno foram utilizadas como carreadores de partículas macro (1000 a 2000 μm) e microgranulares (200 a 600 μm) e implantados em subcutâneo de 60 ratos Wistar, divididos aleatoriamente em 3 grupos: Grupo I (cápsula de colágeno vazia), Grupo II (macrogranular) e Grupo III (microgranular). Decorridos 10, 20, 30 e 60 dias pós-cirúrgico, os animais foram mortos para a remoção do tecido reacional de onde se obteve o extrato. As atividades específi cas (AE) das fosfatases ácidas total (FAT), lisossomal (FAL) e a de baixo peso (FABMr) foram realizadas no pH 5,0 utilizando o p-nitrofenilfosfato como substrato, na presença de inibidores específi cos para cada enzima; a atividade tirosina (Tyr-P) fosfatase foi obtida nas mesmas condições utilizando a tirosina fosfato como substrato. No Grupo I observou-se que a atividade da FAT e FAL não variaram signifi cativamente ao longo dos períodos experimentais, entretanto ambas as enzimas apresentaram atividades signifi cativamente maior (p<0,05) no grupo II que no grupo III na maioria dos períodos avaliados. A FABMr no grupo I foi menor (p<0,001) que nos grupos II (aos 10 e 30 dias) e III (aos 10 dias), mas nos períodos de 20 e 60 dias a FABMr foi maior (p<0,001). A Tyr-P detectada nos períodos de 20 e 60 dias era cerca de 18 vezes maior que aos 10 e 30 dias. Concluiu-se que a atividade da fosfatase ácida total, e suas isoformas FAL, FABMr e Tyr-P é signifi cativamente modulada durante a resposta tecidual ao implante de osso medular inorgânico bovino, tanto em função do período como do tamanho da partícula.

O objetivo deste estudo foi avaliar a evolução do limiar de dor muscular, através da algometria de pressão (LDP) e palpação manual (PM), dos músculos masseter e temporal em 20 pacientes portadores de disfunção temporomandibular (DTM). Todos participantes apresentavam queixa de cefaléia por mais de 6 meses, com características de cefaléia tensional e foram avaliados antes e dois meses após receberem como terapêutica, uma placa oclusal. A intensidade da cefaléia foi avaliada pela escala analógica visual (EAV) e a freqüência, pelo relato do número de episódios de dor por semana. Os resultados evidenciaram redução estatisticamente signifi cante (p<0,05) para intensidade e freqüência das dores de cabeça. Houve elevação do limiar de dor a pressão (LDP) dos músculos temporal direito (p = 0,027), temporal esquerdo (p=0.004) e masseter esquerdo (p= 0,025). Não foi encontrada diferença estatisticamente signifi cante para palpação manual dos quatro músculos avaliados. A análise dos dados permitiu concluir que apesar da redução considerável da intensidade e freqüência dos episódios de cefaléia após utilização de placas oclusais, foram encontrados resultados diferentes quando avaliado o limiar de dor dos músculos masseter e temporal com a algometria de pressão e com palpação manual.

Published: December 2021

A ingestão crônica de álcool pode provocar alterações estruturais em vários tecidos, inclusive no tecido ósseo. O objetivo desse estudo foi avaliar o efeito da ingestão de álcool etílico sobre a morfometria de fêmures e tíbias em ratas. Foram utilizados quarenta animais (4 meses de idade) divididos em cinco grupos (n=8) conforme a dieta líquida administrada: água (Gc-controle), solução alcoólica a 10% (GA1), solução de sacarose a 13,5% (GI1), solução alcoólica a 20% (GA2), solução de sacarose a 27% (GI2). Os grupos GI1 e GI2 receberam dietas controladas com mesmo valor calórico dos grupos GA1 e GA2, respectivamente. Após oito semanas, os animais foram sacrificados e os fêmures e tíbias removidos. O peso úmido dos espécimes foi avaliado em balança analítica. O comprimento e diâmetros (ântero-posterior e médio-lateral) foram medidos com paquímetro digital. Após, foram realizadas radiografias na metade distal dos espécimes para determinar a localização do tecido ósseo trabecular. Nesta região, secções transversais (1 mm) foram obtidas, em local padronizado, a fim de avaliar o percentual médio da área óssea cortical e medular. A análise estatística (ANOVA) não revelou diferenças significativas (P>0,05) para comprimento, diâmetro médio-lateral, diâmetro ântero-posterior e valores percentuais de área óssea cortical e área óssea medular. Pode-se concluir que o consumo de álcool etílico a 10% (que correspondeu a 24,36% das calorias diárias da dieta) e 20% (que correspondeu a 40,10% das calorias diárias da dieta) durante oito semanas em ratas adultas jovens não promoveu alterações morfológicas nos ossos longos.

Published: December 2021

O objetivo deste estudo foi avaliar clinicamente a eficácia do tratamento de hipersensibilidade dentinária por meio do laser AsGaAl e Nd:YAG. Foram selecionados 14 pacientes (72 dentes) da clínica de Dentística da FOSJC–UNESP que apresentavam sensibilidade dentinária aos testes táctil e evaporativo. Os pacientes foram divididos aleatoriamente em dois grupos de sete indivíduos (36 dentes), de acordo com o tipo de tratamento: laser de baixa intensidade de AsGaAl (Three Light - Clean Line) e laser de alta intensidade de Nd:YAG (Pulse Master 600IQ - American Dental Technolo-gies). O laser AsGaAl foi ajustado em 50mW/2J, aplicado com contato, em 4 pontos na região cervical do dente: mesial, médio, distal da face vestibular e um ponto na face lingual. O laser Nd:YAG foi ajustado em 30mJ/10Hz, aplicado por varredura não contato, por 2min. Foram realizadas 4 aplicações, com intervalos de sete dias, e os pacientes atribuíam escores para os testes táctil e evaporativo realizados antes e depois da aplicação do laser. Os dados foram submetidos à análise de variância não paramétrica de Friedman e teste de comparação múltipla de Dunn (p<0,05), e demonstraram que ambos os grupos apresentaram diferença estatisticamente significante entre a condição inicial sem tratamento e a última aplicação do laser para os testes táctil e evaporativo. Concluiu-se que o laser de AsGaAl e o laser de Nd:YAG são efetivos no tratamento de hipersensibilidade dentinária e que não houve diferença significante entre os resultados obtidos entre o laser de AsGaAl e o laser de Nd:YAG.

Published: December 2021

Neste trabalho foi realizada uma análise, in vitro, da capacidade do anticorpo monoclonal (Acmo) 56G anti-Streptococcus mutans de impedir ou interferir na aderência e colonização de S.mutans (cepa GS5) à superfície de corpos de prova confeccionados com Resina Composta Híbrida TPH (Dentsply). Vinte corpos de prova foram preparados, desinfetados com gluconato de clorexidina ou esterilizados por radiação gama com cobalto 60 e incubados em tubos de ensaio contendo meio sacarosado e um inóculo de S. mutans. Metade dos corpos de prova constituiu o grupo tratado e, por isso, recebeu uma alíquota do Acmo; a outra metade destinou-se ao grupo controle. As películas bacterianas aderidas sobre as pastilhas de resina dos grupos tratado e controle foram quantificadas e comparadas através da dosagem de carboidratos e proteínas presentes nas mesmas, além da determinação do número de UFC/ml. Verificou-se que não havia diferença entre a desinfecção com clorexidina e a esterilização por radiação gama, e que o biofilme bacteriano formado na presença do Acmo não diferia daquele formado na sua ausência, tanto nas dosagens de carboidratos e proteínas (p=0,577 e p=0,705, respectivamente) quanto na microbiológica (p=0,488). Conclui-se que o Acmo 56G não foi efetivo na prevenção da colonização da superfície dos corpos de prova confeccionados em resina pelo S. mutans.

Published: December 2021

O propósito desta pesquisa consistiu em realizar estudo clínico-patológico de mixomas odontogênicos arquivados no Serviço de Anatomia Patológica do Departamento de Odontologia da Universidade Federal do Rio Grande do Norte. Ao todo, 14 casos de mixoma foram corados pela técnica de rotina da Hematoxilina e Eosina e examinados à microscopia de luz, descrevendo-se a presença de particularidades histopatológicas, como: áreas de intensa colagenização e remanescentes de epitélio odontogênico. Os dados clínicos referentes ao sexo e idade dos pacientes e localização anatômica das lesões foram obtidos em requisições de biópsias arquivadas. Evidenciou-se acometimento igualitário entre os sexos masculino e feminino. A média de idade dos pacientes ao diagnóstico foi de 33,07 anos, com o sexo masculino revelando valor médio superior (37,14 anos), em comparação com o feminino (29 anos). Em relação ao sítio anatômico, observouse predileção pela mandíbula (57,14 %), havendo maior acometimento da região posterior dos ossos gnáticos (64,29 %). Histologicamente, foram observadas áreas de intensa colagenização em meio ao estroma tumoral em 42,86% da amostra e 6 casos (42,86 %) revelavam ilhotas aparentemente inativas de epitélio odontogênico. Este estudo, apesar de concordar com os achados clínicos comumente relatados em análises retrospectivas de mixomas odontogênicos, descreve uma freqüência relativamente alta de áreas de intensa colagenização e remanescentes de epitélio odontogênico em meio à matriz extracelular destas neoplasias. Além disso, parâmetros para categorização do grau de colagenização da matriz extracelular de mixomas odontogênicos apresentam-se arbitrários e inconsistentes para classificação de mixomas e fibromixomas como entidades patológicas distintas.

Published: December 2021

Our purpose on the present paper was to verify the reproducibility, the variability and the reliability of the analysis of the dental age (DA) and to assess its relationship with the chronological age (CA). Fifty-three panoramic radiographs from 32 female and 21 male Brazilian children, with ages ranging between 120 and 131 months were submitted to the assessment of their DA according to the general14 and the sex-adjusted15 Standards for the Chronology of Dental Mineralization by four examiners. A high intra-observer and inter-observer reproducibility was found for both sexes. The DA obtained with the general standard was lower than the CA for male and female individuals. With the sex-adjusted standard, we observed that the female individuals tend to have the DA lower than the CA. However, when the values for the CA were subtracted from the values for the DA obtained with the adjusted table, only 13.09% of male individuals and 7.03% of female individuals had the DA out of the acceptable limit of ±12 months. When the CA values were subtracted from the DA values obtained with the general standard, 4.76% of male individuals and 12.5% of female individuals were above or below the acceptable limit of ±12 months. Although the results for the differences between the DA and the CA of some examiners were statistically significant, these differences are clinically irrelevant. The dentists do not need previous experience with the method, since it is based on comparisons of the radiographic images of the teeth with standards of mineralization stages. Based on the results, we concluded that the method is highly reproducible both for the comparisons of the results of one examiner and for the comparison of the results of a group of examiners. As expected, it is applicable to the Brazilian population. The Dental Professionals do not need previous experience with the method, since it is based on the comparison of the radiographic images of the teeth with the stages of dental mineralization.

O objetivo do trabalho foi avaliar a influência da dor e ansiedade sobre a freqüência cardíaca (FC) e pressão arterial (PA) de 275 voluntários em situações de urgências endodônticas, selecionados de forma aleatória, entre os pacientes que procuraram o serviço do Pronto Socorro Odontológico da Faculdade de Odontologia da Universidade Federal de Uberlândia (FOUFU). Os voluntários responderam a ficha de anamnese e a Escala de Ansiedade Dental de Corah ainda na sala de espera. A Escala de 11 Pontos em Caixa foi usada para avaliar a sensação dolorosa dos voluntários, em dois momentos: antes do atendimento, para determinar a dor com que chegaram para atendimento e, após o tratamento, para determinar se houve alteração na sensação dolorosa. A PA e FC foram avaliadas através de esfingnomanômetro com coluna de mercúrio, também em dois momentos; inicialmente, com o paciente na sala de espera e, imediatamente ao término do atendimento, com o objetivo de correlacionar o controle eficaz da dor com a variação dos parâmetros cardiovasculares avaliados. De acordo com os resultados obtidos concluímos que a dor e a ansiedade não foram capazes de alterar significativamente a pressão arterial e freqüência cardíaca.

Authors: Foad Ahmed Mohsen , Hamdy Amina , Abd el Fatah Ghada , Aboelfadl Ahmad
Published: December 2021

Objective: To evaluate the effect of different occlusal preparation designs and CAD/CAM materials on the fracture resistance of maxillary premolars endcrowns. Materials and Methods: sixty-four endodontically treated upper first premolars were randomly divided into four groups according to ceramic materials (Vita Enamic and IPS emax CAD) and occlusal preparation designs (Anatomical and horizontal butt joint). After teeth preparation, the restorations were all made by CAD/CAM system (Cerec MCXL). Half of each group had undergone cyclic fatigue testing of 105 cycles with 50N loading force at a frequency of 0.5Hz in a mechatronic chewing simulator machine, and then all samples were loaded to fracture using a universal testing machine with a cross head speed of 0.5mm/min recording the fracture resistance values in N . The specimens were measured and statistically analyzed using using three-way analyses of variance (ANOVA), followed by serial two-way and one-way ANOVAs at each level of the study. P-values were adjusted for multiple comparisons using BENFORRONI correction and the significance level was set at P ? 0.05 for all tests. Results: Vita Enamic endocrowns showed higher fracture resistance values than IPS e max specimens. Conclusions: Vita Enamic endocrowns with anatomical preparations were found to be more favourable restoring endodontically treated maxillary premolars. KEYWORDSEndocrowns; All-Ceramic; Fracture; Cyclic loading; CAD/CAM
On the 180th anniversary of Emil Theodor Kocher, a Swiss thyroid surgeon

Published: December 2021

August 25, 2021 marks the 180th anniversary of the birth of the renowned physician Emil Theodor Kocher. He was a man whose talent has manifested itself in various fields of medicine. Nowadays it is impossible to imagine a doctor who does not know the name of Kocher, because he is the author of many surgical methods and techniques that are still valid, despite advances in modern medicine. Furthermore, some of the instruments designed by Kocher are still used in surgery. In addition to the biography of Kocher, this article considers information about his work in the field of thyroidology, for which he received the Nobel Prize in 1909. Kocher has performed more than 5,000 thyroidectomies during his career. Thanks to the technique he developed, the mortality rate of that surgery decreased at least fortyfold. In those days there were not researches on functions of the thyroid gland, but Kocher noticed that total thyroidectomy leads to serious consequences. Therefore he refused to do such surgeries without invariable indications.

TextMix: using NLP and APIs to generate chunked sentence scramble tasks
Authors: Albertson Brendon
Published: December 2021

A Computer-Assisted Language Learning (CALL) application, TextMix, was developed as a proof-of-concept for applying Natural Language Processing (NLP) sentence chunking techniques to creating ‘sentence scramble’ learning tasks. TextMix addresses limitations of existing applications for creating sentence scrambles by using NLP to parse and scramble syntactic components of sentences, while connecting with Application Programming Interfaces (APIs) to provide repeated exposure to authentic sentences in the context of texts such as Wikipedia articles. In addition to identifying a novel application of NLP and APIs in CALL, this project highlights the need for teacher-friendly interfaces that prioritize pedagogically useful ways of chunking text.
Online translators for L2 writing: a comparison of student and teacher
perspectives
Authors: Alm Antonie , Watanabe Yuki
Published: December 2021

This short paper reports on the preliminary findings of a study into the
use of Online Translators (OTs) by university language students. Students of
Chinese, French, German, Japanese, and Spanish and their teachers responded
to comparative surveys on their respective use and evaluation of OTs for L2
writing in formal language learning contexts. Findings indicate that
teachers have little awareness of the range of strategies students apply
when using OTs as writing tools. Concerns of OT misuse for cheating or as a
replacement for language learning seem largely unfounded. Students, however,
perceive a lack of guidance for the appropriate use of OTs. Preliminary
findings suggest that teachers need to review their assumptions about
students’ OT practices and that both students and teachers would benefit
from technical and pedagogical OT training.

With the COVID-19 outbreak at the beginning of 2020, many language
teachers worldwide who were successfully implementing face-to-face teaching
had to abruptly switch to online education, which was not something they
were trained for or had experience with. Were they successful? The present
study asked students from Turkey (TUR), Poland (POL), the Republic of North
Macedonia (RNM), and Bosnia and Herzegovina (B&H) to evaluate their
teachers’ professional adaptation and success during the first emergency
online teaching semester. The results of the study showed that there were
important similarities in the ways students in the examined four countries
approached and evaluated the level of professionalism of their teachers in
the first COVID-19 period regarding their teachers’ computer literacy,
online teaching skills, creation of materials appropriate for online
teaching.
Effects of repeating after stimuli sounds during computer assisted HVPT
on Japanese learners’ perception and production of English
fricatives
Authors: Iino Atsushi , Wistner Brian
Published: December 2021

This study investigated the effects of using an online High Variability
Phonetic Training (HVPT) program for university students whose first
language is Japanese and who studied English as a foreign language. The
target sounds were English fricatives, which many of the participants felt
were challenging to distinguish and articulate. The training was conducted
for five weeks; each week consisted of three HVPT sessions. The training
process consisted of an initial explanation of how to articulate the sounds
followed by a video that showed the physical articulative movements. The
participants listened to stimuli sounds, produced the sounds after each
stimulus, and completed an identification task. Based on pre and posttests,
the perception performance of the participants improved significantly
through the HVPT training. Regarding production, a positive effect was found
for one phoneme, while no difference was found for the other. Questionnaire
results were generally positive but indicated the need for explicit
instruction for some of the fricatives that exhibited relatively lower
successful production and perception rates.

Promoting common ground building in L2 cross-cultural conversations
Authors: Mirzaei Maryam Sadat , Meshgi Kourosh , Nishida Toyoaki
Published: December 2021

Teaching culture out of context may not be the optimal approach, yet it could be achieved by immersive technologies. This study uses an immersive theme-based environment and focuses on cross-cultural interactions between learners of different cultures in goal-oriented scenarios. We collected interactions among learners with different cultural backgrounds and annotated common ground formation and conversation breakdowns in those interactions. Next, we recreated the scenarios in a 3D immersive environment using an in-house situation creation toolkit to enable experiencing the situation by using choices to navigate the conversation and observing the consequences. In case the conversation derails, we provide timely scaffolding by offering appropriate communication strategies to rebuild common ground. Learners can be the actors of the scenarios but can also be the observers by switching between roles and points of view. Preliminary experiments with 20 L2 learners of English from different cultures showed that practicing with immersive conversational game-play is effective for raising cultural awareness and learning to choose appropriate strategies for smooth interactions.

Cultural diversity is one of the global issue underlined by UN. Indonesia known as a very rich country has more than 300 ethnic cultures. One of them is Islamic architecture and cities that spread in the North Coast of Java. In the span of 6 centuries, we can still witness the existence of these works as living heritage that saves tangible and intangible culture. The role of the community is very significant which are take care, plan and develop  for the next generation. However, the changes that have occurred are caused by urbanization, and the shift in the political and economic map poses a threat to the sustainability of this legacy. The purpose of writing this article is to provide views on the importance of an approach to the process of preserving living cultural heritage by involving community participation in order to maintain the sustainability of cultural heritage. The locus in the North Coast of Java is based on the consideration that the cities in this region inherit the distinctive Islamic culture of the Coastal Java and its dynamics. The digital-legacy approach combines the use of information technology in this case is Web GIS for archiving artifact data. Meanwhile, the living heritage approach encourages community participation to play an active role with stakeholders on an ongoing basis in the preservation of artifacts. Kudus Kulon is an interesting and unique case with the Gusjigang community who have cared for Omah Joglo Pencu for almost three centuries. Architectural sustainability – Muslim cities include historical and cultural sustainability, function, and maintenance
Empoderamiento femenino y asociaciones productivas comunitarias: Una revisión sistemática de literatura

Published: December 2021

Pese a estar presente en diversas discusiones de las ciencias sociales y los estudios de género la promoción del empoderamiento femenino ha alcanzado un renovado protagonismo a partir de su inclusión en los Objetivos de Desarrollo del Milenio y de Desarrollo Sostenible. Dentro de las estrategias priorizadas para lograr este empoderamiento las agencias internacionales y gobierno nacionales han apostado por la generación de procesos asociativos en torno a actividades productivas. En este documento se presenta una revisión sistemática de literatura que tiene por objetivo analizar el impacto de pertenecer a asociaciones productivas rurales en las diferentes dimensiones del proceso de empoderamiento, a saber: recursos, agencia y resultados. Con este fin, se utiliza una metodología de revisión sistemática de literatura de cinco artículos cuantitativos y ocho artículos cualitativos. Para el caso de los cuantitativos, se presenta una organización basada en el componente del proceso de empoderamiento evaluado y se estima el tamaño del efecto estandarizado; para el caso de los cualitativos, se realiza un análisis de contenido de los hallazgos siguiendo la misma organización por dimensiones del proceso. Los resultados muestran que el impacto de la pertenencia a cooperativas ha sido estudiado de forma mayoritaria desde el enfoque de empoderamiento como agencia, entendida como toma de decisiones; y que, para este componente en particular, los tamaños de los efectos (d de Cohen) son significativos, aunque pequeños (δ=0,05; 0,22).

El objetivo de este trabajo fue determinar el carácter predictivo de la socialización organizacional y la salud mental positiva ocupacional sobre el compromiso organizacional en docentes de educación superior. Se contó con una muestra de 279 docentes de instituciones de educación superior que firmaron un consentimiento informado. El 54.5 % de los participantes eran mujeres, con una media de edad de 44.05 años (DE = 10.26). Los participantes respondieron el Inventario de Socialización Organizacional (ISO), el Cuestionario de Salud Mental Positiva Ocupacional (SMPO) y la Escala de Compromiso Organizacional (CO), y para el análisis de datos se aplicaron estadísticos descriptivos, un análisis de correlación y una regresión lineal múltiple con método de pasos sucesivos, ingresando por separado cada dimensión del compromiso organizacional como variable dependiente. Como resultado, se identificaron correlaciones de moderadas a débiles entre las variables de estudio, y se encontró que los modelos finales indican que las dimensiones de perspectivas de futuro y socioafectiva predicen en un 38 % el compromiso afectivo; que las perspectivas de futuro, la espiritualidad y la edad predicen en un 22.8 % el compromiso normativo; y que la dimensión perspectivas de futuro predice en un 9.2 % el compromiso de continuidad. Concluimos que las expectativas del docente sobre su desarrollo en la institución, así como sus interacciones a nivel socioafectivo y espiritual con el contexto laboral, son factores que influyen parcialmente en su vinculación con la organización educativa.

Aunque el consumo de marihuana es altamente prevalente entre universitarios de Argentina, poco se sabe respecto a los factores que permiten distinguir a los consumidores frecuentes de marihuana de quienes consumen esporádicamente. Por esta razón, en el presente trabajo se indagó sobre las posibles variaciones en los contextos de consumo, motivos de consumo, normas percibidas y estrategias conductuales de protección entre universitarios con consumo frecuente o esporádico de marihuana, y se analizó la utilidad de este conjunto de variables para distinguir entre estos los tipos de consumidores mencionados. Para ello, se contó con una muestra de 1083 estudiantes universitarios argentinos que completó una encuesta en línea sobre el consumo de sustancias. En particular, este trabajo se realizó con la submuestra que reportó consumir marihuana en los últimos 30 días (n = 158; 51.3 % mujeres). Dicha encuesta interrogaba sobre el consumo de marihuana y las consecuencias negativas asociadas, así como por motivos de consumo, normas sociales percibidas y estrategias conductuales de protección. Como resultado, los consumidores frecuentes presentaron mayor cantidad de consecuencias negativas (M = 4.92) que los consumidores esporádicos (M = 1.82; p ≤ .05), y se halló un perfil distintivo en un conjunto de variables. A nivel multivariado, los motivos de animación (or = 1.230; p ≤ .05), las estrategias conductuales de protección (or = .941; p ≤ .05), el consumo en solitario (or = 2.024; p ≤ .05) y el consumo en fiestas universitarias (or = 2.669; p ≤ .05) discriminaron significativamente entre ambas clases de consumidores. En general, los hallazgos revelaron subpoblaciones heterogéneas de consumidores de marihuana que difieren no solo en el consumo y sus consecuencias, sino también en los contextos de consumo y en un conjunto de variables relevantes. Estas subpoblaciones distintivas requieren de intervenciones diferentes y específicas.
Диалектна основа на Pastirska knigha (1848) от Андреа Канова. 1. Фонетика
Authors: Селимски Людвиг
Published: December 2021

Епископ А. Канова се е старал текстът му да е достъпен, разбираем не само за католиците в България – в него се явяват и консонантите в, ф и х, които липсват в диалекта на католиците. А ограничена (в 11 думи/16 форми) е появата на характерния за диалекта на католиците нов вокал ì на мястото на акцентирано è. За отбелязване е и появата на вокала е на мястото на а в наречието delèc ‘далеко’ и в прилагателното delecni ‘далечни’, както и на диалектната форма sе на мястото на книжовната sa ‘са’ (за 3 л. мн. ч., сег. вр.) на спомагат. глагол съм. Всички тези фонетични особености са безспорно свидетелство за това, че изследваният текст е изграден в основни линии върху диалекта на католиците.
Диалектни успоредици между славянския север и юг
Authors: Антонова-Василева Лучия
Published: December 2021

Докладът разглежда произношението на назални гласни като специфично фонетично явления, разпространено днес в южния и в северозападния дял на славянските езици. Разглеждат се примери за назализация в българските говори от различни части на българското езиково землище. Обсъждат се схващанията за произхода на назалите в славянските и в индоевропейските езици във връзка с въпроса за наличието на назализация в съседните на българските селища области, населени с носители на албански, арумънски и гръцки диалекти, в които са отбелязани фонетични явления, сходни със славянския назализъм.

The lipid and fatty acid profiles of 14 marine macroalgal species from the Madeira Archipelago, including two green (Ulvales and Dasycladales), three red (Corallinales, Bonnemaisoniales, and Ceramiales) and nine brown (Fucales, Dictyotales, and Sphacelariales) species were characterised in order to determine their potential use for animal and human nutrition. The total lipid content of species analysed was generally low, varying from 0.2 to 5.2% of dry weight. All species presented an omega 6/omega 3 (n-6/n-3) ratio lower than 10, as recommended by the World Health Organization for proper human health. Polyunsaturated fatty acids (PUFA), including linoleic acid and alpha-linolenic acid were exceptionally high in the green macroalga Ulva sp. Red macroalgae were rich in n-3 long-chain PUFA, particularly Asparagopsis taxiformis, which contained 6.6% of docosahexaenoic acid, and Halopithys incurva with 9.3% of eicosapentaenoic acid. Within Ochrophyta, Dictyota dichotoma is an interesting source of n-3 PUFA due to its high stearidonic acid proportion (8.0%). In addition, H. incurva contained a high proportion of both mono- and digalactosyldiacylglycerols. According to their lipid profiles, most macroalgae analysed might be considered of particular interest for their potential exploitation for human nutrition and livestock and aquaculture production.
Learning about reflective PPG for SpO2 determination using Machine Learning

Reflective Photoplethysmography (PPG) sensors are less obtrusive than transmissive sensors, but they present patient-dependent variations in the so-called “Ratio of Modulation” (R). Thus, the conventionally employed calibration curves for determining peripheral oxygen saturation ( SpO2) may report inaccurate values. In this paper, we study the possibility of overcoming these limitations through Machine Learning (ML). For that, we show the results of applying several algorithms and feature combinations to PPG data from a human hypoxia study. The study was performed on ten healthy subjects. Their target oxygen saturation was reduced in five steps from 98- 100% to 70-77% through an oral mask. Blood Gas Analysis (BGA) was performed five times for each saturation level to measure the arterial oxygen saturation. PPG data were acquired from a reflective pulse oximeter placed in the subjects’ ear canals. PPG signals were pre-processed, and several features in the frequency and temporal domain were calculated. For the ML algorithms’ input, we explored different combinations of the features. We trained and validated the algorithms with the data from seven patients, and we tested them on three. Finally, we performed leaveone- out cross-validation to ensure the universality of the methods. The results show a good agreement of the predictions with the BGA values for Linear Regression, k- Nearest Neighbors, Stochastic Gradient Descent, and Neural Network for all input feature combinations with an average RMSE in the range of 3%. However, the performance of the Linear Regression was not beaten by the Neural Network, even for overfitting with 2000 hidden layers. The combination of R calculated with a Fast-Fourier Transform and ACRMS.red/ACRMS.irsignificantly improved the results, reducing the RMSE by 25%. This work demonstrates that a straight-forward Linear Regression is capable of determining SpO2with reflective PPG independently of the subject if the ratio ACRMS.red/ACRMS.ir is considered simultaneously with the Ratio of Modulation.
