Enfermedad periodontal en latinoamerica: enfoque regional y estrategia sanitaria
Authors: Gutiérrez Romero Fabiola , Padilla-Avalos César-Augusto , Marroquín Soto Consuelo
Published: December 2022

La periodontitis es una enfermedad crónica de tipo no transmisible, caracterizada por ser inflamatoria, infecciosa y multifactorial. Es una de las enfermedades más prevalentes en cavidad oral hasta el punto de ser considerada una epidemia. Esta condición se puede prevenir y tratar; sin embargo, las medidas sanitarias siguen siendo insuficientes para lograr un control efectivo en la práctica clínica. La progresión de la periodontitis se basa en la presencia de un microbioma disbiótico que desencadena una respuesta inflamatoria del huésped, lo cual se traduce clínicamente en la pérdida del tejido de soporte dental y provoca su pérdida. Cabe destacar la importancia del conocimiento sobre la relación existente entre la enfermedad periodontal y la salud sistémica, la bidireccionalidad y la necesidad del manejo multidisciplinario. La periodontitis representa un problema para la salud pública de los países de Latinoamérica y es responsabilidad que los estados gubernamentales, así como de todo el personal sanitario, ejecutar estrategias de salud con el fin de reducir el impacto de la enfermedad en las poblaciones más vulnerables. El objetivo del presente ensayo es analizar los factores por los cuales la enfermedad periodontal sigue siendo altamente prevalente y, así mismo, promover la prevención de la enfermedad y medidas de control.

‚Mi ricordo′, ‚je me souviens′: ich erinnere mich
Authors: Gerstenberg Annette , Pagenstecher Cord
Published: December 2022

Im interdisziplinären Spannungsfeld zwischen Geschichtswissenschaft und Linguistik werden in diesem Beitrag Oral History-Interviews als zentrale Ressource beider Fächer ausgewertet. Die Fallstudie untersucht die Sprache des Erinnerns in italienischen und französischen lebensgeschichtlichen Interviews des Archivs Zwangsarbeit 1939-1945 und des LangAge-Korpus. In fünf Arbeitsschritten setzt sie die in der Oral History-Forschung etablierte Herangehensweise, Hypo­thesen aus den Daten heraus zu entwickeln, mit korpuslinguistischen Methoden um. So werden die Vorkommen der Personalpronomina wir und ich verglichen, und Schlüsselwörter (Keywords) und häufige Wortkombinationen (N-Gramme) er­mittelt. Diese quantitativen Analysen werden durch die exemplarische Analyse häufiger Wendungen wie ‘ich erinnere mich’ oder ‘in einem bestimmten Moment’ vertieft. Dabei werden der biographische Zugang der Oral History und das geschichts­­wissenschaftliche Kontextwissen mit den Ergebnissen der korpus­linguistischen Analyse zusammengeführt. Als problematisch erweisen sich dabei unterschiedliche Transkriptionsstandards zwischen Oral History und Linguistik. Die neue Forschungs­umgebung Oral-History.Digital unterstützt in Zukunft solche sammlungs­­über­greifenden und doch quellennahen Analysen lebensgeschichtlicher Interviews.
Do menu costs lead to hysteresis in aggregate output? The experiences of some agent-based simulations
Authors: Váry Miklós
Published: December 2022

The transitory shock of the financial crisis of 2008 pushed most economies to permanently lower-level growth paths than those prevalent before the crisis, which can be considered as a manifestation of hysteresis. It is well known that some fixed adjustment costs lead to hysteresis in aggregate output. This paper investigates within an agent-based model, whether the fixed costs of price adjustment (menu costs) lead to the same result. Hysteresis emerges in some simple variants of the model independently of firms being assumed boundedly or perfectly rational, but these model variants fit to the empirical data poorly. The model's empirical performance can be improved by assuming that firms are hit by idiosyncratic productivity shocks, but these shocks eliminate hysteresis generated by menu costs. However, hysteresis survives even in their presence, if it is generated by demand-supply interactions, i.e., positive feedbacks from the output gap to potential output. Our conclusion is that if one would like menu costs to serve as an at least as relevant explanation for the hysteretic dynamics of aggregate output as demand-supply interactions, one has to find an alternative assumption to replace idiosyncratic productivity shocks as a mechanism to assure good empirical fit for the model.
Primary schoolboys’ embodied relationships in the classroom
Authors: Katila Julia , Niemi Kreeta
Published: December 2022

Interpersonal touch is crucial for establishing interpersonal bonds. Drawing on the framework of haptic sociality, this study explores the interactional emergence of embodied relationships among second-grade schoolboys as part of ongoing classroom activity. Focussing on forms of body-to-body behaviour that occur during classroom activities, we describe four different types of touch occurring between the boys – supporting, nudging, wrestling and grooming – and how they are collaboratively accomplished, how they change from one type to another, and how they are deployed as embodied negotiation withing a continuously unfolding embodied relationship. Complementing previous studies on embodied relationships among schoolgirls, our study focuses on the haptic social life of schoolboys.

To analyze the outcomes of severe acute kidney injury in patients with paraquat ingestion. This retrospective analysis of case records was done in our institute, a tertiary care government teaching hospital, over a period of 4 years. Of the total 1310 acute paraquat poisonings during this period, severe acute kidney injury (AKI), referred for nephrology management was observed in 60 patients. Common symptoms at presentation include vomiting, oral ulcers, and abdominal pain. Oliguric AKI was present in 26%. Need for renal replacement therapy was observed in 95% of the cases. Mortality was observed in 38 of the 60 patients (68%). Factors associated with mortality on Cox regression analysis include amount of consumption. Estimated duration of survival on analysis curves was 8 days in 50% after admission and 15 days after consumption in 50%. Paraquat poisoning is associated with grave outcomes of morbidity and mortality. Severity of AKI is significant in this poisoning. Amount of consumption, latency of referral play a major role in outcomes.

Authors: Isidoro Fabiana Goulart Rabelo , Côrtes Maria da Conceição Juste Werneck , Ferreira Fabiane Ribeiro , D’Assunção Alexandra Dias Moreira , Gontijo Eliane Dias
Published: December 2022

Resumo: Introdução: A educação interprofissional (EIP) procura desenvolver habilidades colaborativas dos profissionais de saúde para a melhoria do cuidado ao paciente. Objetivo: Essa revisão explora as estratégias educacionais não pontuais utilizadas na formação interprofissional, na graduação em saúde, identificando seus potenciais e suas fragilidades. Método: A busca incluiu artigos publicados nas bases de dados BVS (LILACS), Cochrane, CINAHL, Embase e MEDLINE. Definiu-se a questão de pesquisa pelo anagrama PICO: selecionaram-se estudos que incluíssem, pelo menos, dois cursos de graduação em saúde, sendo um deles de Medicina, e que relatassem estratégia educacional mínima de 15 horas e sua avaliação. Resumos publicados em congressos, opiniões, editoriais e revisões sistemáticas foram excluídos. Resultado: Avaliaram-se 28 estudos publicados entre 2005 e 2019, sendo 31% no último biênio. Prevaleceram a simulação (36%) ou o uso de métodos combinados (29%) na avaliação de atitudes dos alunos, a compreensão dos papéis dos profissionais de saúde, o trabalho em equipe, a comunicação e o conhecimento em resposta à intervenções de EIP. Predominaram estudos nos domínios: papéis e responsabilidades (75%) e trabalho em equipe (64%). A abordagem de valores e ética (32%) e de comunicação (28%) foi menos frequente. Dos artigos, 18 (64%) apresentavam dois ou mais objetivos e seis (18%) buscavam estudar, em conjunto, os quatro domínios da EIP. Entre as intervenções utilizadas como estratégias de ensino, 36% (dez estudos) eram de simulação; 29% (oito), métodos combinados; 18% (cinco), prática clínica (trabalho colaborativo em unidades ambulatoriais ou enfermarias); 14% (quatro), observação direta (shadowing); 11%, aprendizagem baseada em problemas; e dois, aprendizado on-line (e-learning) e workshop. A qualidade geral dos estudos incluídos foi baixa, atendendo de dois a cinco dos seis critérios de qualidade. O cegamento do avaliador não foi citado em 25 publicações. O trabalho colaborativo em cenários reais é descrito como o mais eficiente. Conclusão: A EIP vem sendo incorporada ao processo de formação na saúde, e múltiplas estratégias focadas em resultados e baseadas em competências otimizam a construção de relações efetivas e o desenvolvimento de habilidades para a prática colaborativa. A fragilidade dos artigos aponta que a EIP de estudantes ainda constitui grande desafio para as instituições formadoras.

Interrogative particles in polar questions: the view from Finnish and Turkish
Authors: Gonzalez Aurore
Published: December 2022

The strategy used for forming polar questions varies across languages. While in some languages, polar questions are formed using a raising intonation, in others, polar questions are formed using an interrogative particle. This paper focuses on a type of interrogative particles which has not received much attention in the semantic literature. I call these particles polar interrogative particles. On the empirical side, I identify the signature properties of polar interrogative particles, and show that we need to draw a distinction between (at least) three types of interrogative particles cross-linguistically. On the theoretical side, I develop a full-fledged semantic analysis of these particles and of the questions where ther occur. The proposed account contributes to a better understanding of the source of presuppositions in questions and their projection behavior, and of the interaction between different sets of alternatives (namely, question and focus alternatives).
Prioritising Command-and-Control Over Collaborative Governance: The Role of the Information Regulator Under the Protection of Personal Information Act
Authors: Bronstein Victoria
Published: December 2022

Although the Protection of Personal Information Act 4 of 2013 (POPIA) wholeheartedly adopts the command-and-control features of the EU General Data Protection Regulation (GDPR), POPIA does not include many of the collaborative governance mechanisms in the GDPR. POPIA dilutes the accountability requirements in the GDPR. It rarely requires responsible parties to generate or keep documentation and there is no equivalent of European Data Protection Impact Assessments in the South African Act. This affects the regulation of automated processing that involves profiling. The European system of certifications is also not included in POPIA. POPIA includes a system of codes of conduct but even they have a more peremptory nature. The absence of collaborative governance mechanisms in POPIA constitutes a missed opportunity to build a culture of enhanced data protection in South Africa. The Information Regulator has the task of giving many exemptions and prior-approvals under the Act. The newly constituted Information Regulator will find itself exposed as it faces a particularly difficult mandate.
From isolation to constellation: Narrative focalisation in current technology disclosures
Authors: Sancho Guinda Carmen
Published: December 2022

In this article, I explore focalisation in the mediated account of universitytechnology disclosures, a relatively recent digital genre for science andtechnology commercialisation and institutional promotion through onlinedissemination and outreach. Born in academic settings, this genre is still in-themakingand highly susceptible to discursive hybridity. My study draws on aneclectic framework that combines the principles of Netnography with NarrativeInquiry, (Critical) Genre and Multimodal Analysis, and Positioning Theory toexamine the teller’s role and the telling practices contained in two types ofinterrelated documents published by the Universidad Politécnica de Madrid onits webpage: the institution’s current Technologies Portfolio and a series of salient inhouseinnovative technologies/projects rendered in comic-book format, both intheir English version.

The scrutiny of the 134 samples of the Portfolio and of the 12 instances ofcomic-books reveals how the hybridity generated by digital affordancesinfluences narrative and, along with it, promotional strategies. I lay specialemphasis on the concept of ‘narrative focalisation’ and attempt to answer thefamous Goffmanian question “Who is speaking?”, making the point that genrenetworking is a way of telling and ultimately of institutional branding.
Chemical composition of Artemesia herba-alba essential oil and its larvicidal and pupicidal effects against Culex pipiens (Diptera; Culicidae)
Authors: Abdelali Salma , Souttou Karim , Kacimi-Elhassani Mohamed , Aissaoui Lynda , Bendachou Hamid
Published: December 2022

Artemisia herba-alba Asso (A. herba-alba) (Asteraceae) is widely used in herbal medicine as it is a mine of natural molecules such as davanone, which is an interesting product on the international market. The present research proposes a method for controlling the late larval (L4) and pupal stages of Culex pipiens based on the essential oil of A. herba-alba. The aerial part of this plant was extracted by hydrodistillation and then analyzed by gas chromatography coupled with mass spectrometry (CPG/SM) to determine its chemical composition. Three concentrations (1, 5 and 10 μl/ml) were prepared and directly tested on larvae (L4) and pupae under laboratory conditions to measure LC50, LC90, LT50, and LT90 values. The yield obtained in this study was 1.5%. Further, the analysis showed that the oil of A. herba-alba is a davanone chemotype that consists mainly of davanone (48.8%). The efficiency of this essential oil for toxicological parameters (LC50 and LC90) were 3.278 μl/ml and 7.573 μl/ml for larvae, and 1.213 μl/ml and 2.288 μl/ml for pupae. This study indicates that the essential oil of A. herba-alba has toxic properties for Cx. pipiens larvae and pupae. These results are encouraging and open up exciting and promising horizons for its application in the production of bioinsecticides.
Factores psicosociales asociados a la reincidencia de intentos de suicidio en pacientes con enfermedad mental atendidos en el Hospital Mental de Antioquia, Colombia, 2014-2016
Authors: Velásquez Vélez Angie Vanessa , Medina Tamayo Marisol , Pérez Villegas Isabel Cristina , Trujillo Orrego Natalia
Published: December 2022

Objetivo: Este estudio buscó analizar el comportamiento de factores psicosociales (características sociodemográficas, diagnóstico principal, método de intento, cognición y comportamiento) en relación con el número de intentos de suicidio en pacientes con diagnóstico de enfermedad mental, atendidos en el Hospital Mental de Antioquia, entre los años 2014 y 2016, además de evaluar la relación asociativa de dichos factores en la reincidencia por intento.
Metodología: Estudio de corte transversal, que analiza, en 248 personas con diagnóstico de afecciones mentales, la asociación mencionada. Para ello, se describe, primero, el perfil sociodemográfico y clínico; luego, se construye un modelo de regresión logística multivariada, para evaluar la asociación de factores psicosociales con el riesgo de reincidencia por intento.
Resultados: La población se caracterizó, principalmente, por ser joven (12-20 años) y de género femenino (62,9 %), siendo la reincidencia del 40 %. Entre los hallazgos de mayor relevancia se informa que se presenta una mayor proporción de consumo de sustancias  psicoactivas y bajo apoyo familiar/social en pacientes con cuatro episodios respecto a quienes tuvieron un intento. Los predictores explicativos del riesgo de reincidencia por intento de suicidio fueron el trastorno depresivo recurrente, escaso seguimiento psiquiátrico y el uso de métodos de menor letalidad (corte de muñecas).
Conclusión: Los resultados son claves en el marco de la prevención del suicidio, en tanto identifican factores que contribuyen al aumento del número de intentos y su reincidencia, y coincide con la ventana temporal de inicio de vigilancia del evento en el sistema colombiano.

Globally, large reserves of low grade or lignite coal are available. Low-ranking coal contains high mineral content, moisture content, and low calorific value. The major problem in coal is sulphur and ash When used for combustion, this type of coal imposes harmful impacts on the environment. It results in the production of greenhouse gases and ash, which are hazardous for the environment and human health. Usually, the demineralization and desulphurization process is used to remove the minerals matters before its use in industrial processes such as combustion, carbonization, gasification and liquefication. Which are harmful to the environment if combusted untreated. Therefore, the number of upgrading technology is being used to reduce the mineral matters from coal and save the environment. The current paper reviews the potential of demineralization and desulphurization processes to enhance the usability of lignite coal. Moreover, it focuses on preserving the high-grade coal which is already depleted in abundance.

This paper presents the analysis of coefficient of thermal expansion (CTE) of solder ball on a ball grid array (BGA) through digital image correlation (DIC) technique. The assessment of thermal mechanical properties of semiconductor component is a main challenge due to the sensitivity of micro-scale components to heat. However, the CTE analysis of BGA is significant to address the issues of thermal mismatch strains which lead to failure. Meanwhile, the measurement of solder ball heat expansion is in microscale and heated conditions where the traditional method of strain measurements is ineffective. In this analysis, a micro DIC system was used to measure the strain value of solder balls when it was subjected to temperature loading in a heating stage. The actual temperature of the solder ball was measured using a thermocouple inside the heating stage to ensure uniformity of the temperature. The measured strain during the specific temperature was obtained and plotted for CTE using linear analysis. The average value of CTE for the measured solder ball was 27.33 × 106 / oC. The results indicated that the measurement was close to the reference value of solder ball CTE. This analysis provides a reliable analysis of BGA using a developed DIC method.

Rainwater Harvesting System (RWHS) is a collection and storage of rainwater for future use and have many benefits related to the economy, environment, technology, and society. Malaysia is well positioned to harvest rainwater because of number of rainy days in Malaysia is high and average of rainfall amount 2500 mm annually. Because of the effects of the topography of Peninsular Malaysia, rainfall distribution varies significantly. Thus, rainfall data analysis for rainwater harvesting potential should be made based on local climate and influences from the monsoon. The objective of this study was to analyse the rainfall data for rainwater harvesting potential in Politeknik Ungku Omar (PUO). To simplify analysis, rainfall distribution is discussed within two monsoons which is Southwest monsoon and Northeast monsoon while rainfall trend is determined under the year 2000 to 2019. The result indicates that PUO will be potential for RWHS regarding to high number of rainfalls event and increasing trend in annual rainfall amount in that area. Further research is clearly needed to investigate the roof size and water consumption to increase the effectiveness of the RWHS.

Sago palm is the oldest tropical plant that has been explored to get starch. However, untreated sago waste is often disposed to the nearest river, and it will contribute to the environmental problem. Since it still has a high content of starch, namely amylose and amylopectin, it has the potential to be turned into other high value-added products such as poultry feed, bioassay, and substrate in laccase production. However, before it can be converted, it must be dried to the desired moisture level. Its chemical-physical properties must be evaluated before it can be applied to ensure its composition fulfils the substrate specification for other usages. After it has undergone the drying process via the fluidized bed dryer, the analysis of its chemical-physical properties, determination of its moisture content, fat content and solubility in a distilled water must be performed. The results showed the final moisture content of samples were MCf=9.2-10.9 w/w% that fulfil the minimum specification; MCf≤12 w/w%. In addition, the fat content of samples was <1%, and the water solubility increased at a higher temperature. This occurred due to the gelatinization process when the water bath temperature exceeded 60oC. Besides, it was determined that the optimum drying temperature was achieved at T=106.6oC with the optimum drying time was t=56 minutes, and the optimal temperature of the water bath was at T=60oC. These optimal conditions are very crucial and should be considered as the sago pith tends to be retrograded.

Ultrasonic horn is utilized in order to enhance the amplitude of vibration transmitted by the transducer in an ultrasonic machining system. It plays a vital role in vibration amplification to a magnitude suitable for efficient machining of materials. Ultrasonic machining system has to operate at a frequency of at least . Therefore, horn may be subjected to high magnitude of stresses leading to failure. Mechanical horn is designed to get optimum vibration amplification while keeping stresses in acceptable limits. In this research an ultrasonic compound horn was designed with through cutout of uniform diameter. The performance of ultrasonic horn was observed by varying the cutout diameter by modelling horns of four different materials: titanium, aluminum, steel and stainless steel respectively. Modal analysis was performed for computing modal frequencies in the axial direction, whereas harmonic analysis was carried out in order to determine vibration amplitude, stresses and factor of safety. The effect of varying frequency ratio on vibration magnification, stresses, and factor of safety were also investigated. The axial modal frequency was observed to increase, whereas amplitude of vibration and stresses were observed to decrease by increasing the cutout size. Titanium was found to be the most suitable material for ultrasonic horns, because it provided up to 159.4 % more amplitude of vibration and 3 times higher safety factor thus operating life as compared to other materials.

At the current stage of the development of linguistics, the triple scientific interest is updated towards the theory of the comparison of languages, towards the theory of translation and towards intercultural communication as a consequence of the cardinal changes in the political and cultural life of the society. The important place in translation theory is occupied by grammatical problems. To make the correct grammatical transformations, the translator/interpreter must thoroughly know the similar and distinctive features between the original language and the language of the translation, which is the object of comparative grammar. In general, the grammatical categories adequately reflect the conceptual framework of the world, manifesting its basic invariants. In grammatical categories there are several differences that are the cause of semantic differences in consequence of specific worldviews and particular linguistic world pictures. For example, when comparing the categories and grammatical forms of the Spanish and Ukrainian languages, there is a lot of difference between the number and gender of the suative noun. In addition, in the Spanish language there is the category of determination/indeterminacy that is manifested in the presence/absence of the article, while in the Ukrainian language there is the grammatical case in the noun. The most significant differences between the two languages analyzed are observed in the grammatical categories of the verb, particularly in aspect, tense, mood and voice.

The public complaints about health are on the rise as a result of mobile phone usage. Limits on the radiation strength emitted by these devices have already been recommended by standard bodies such as The Federal Communication Commission (FCC) of the United States and the International Commission on Non-Ionizing Radiation Protection (ICNIRP) to safeguard public from excessive exposure to electromagnetic fields. Some recent research have found that long-duration use of calls on mobile phones increases the incidence of health hazards and has negative consequences. After survey the research on investigation of specific absorption rate (SAR) in the human head is becoming increasingly essential. In proposed work, Investigations were done on how human head model and electromagnetic source interacted. The goal of this work is to demonstrate that the one layer head model is not a good model rather appear to be unreliable to evaluate SAR since genuine human skull tissue is not modelled in the same way. But investigation of SAR in six layers (Brain, CSF, Dura, Bone, Fat and Skin) human head appears better and reliable. Affection to the six layered human head may be dominant when exposed to electromagnetic (EM) fields.

Compressive Sensing Scheme for image reconstruction presented in this paper is depending on a combination of Orthogonal Matching Search and a 13/19 triplet half band filter bank (THFB) which is resulting from 1/2-band polynomial. Here, the consideration is made for 13/19 triplet half band wavelet filter sets. The half-band polynomial is applied which is generalized and used to receive the required frequency response. The image reconstruction is done later based on this. The designed triplet wavelet filters give a sparse image which is used for the input image. Gaussian probability density function and the Orthogonal Matching Pursuit (OMP) are presented for reconstructing the image. The results and observations demonstrate that the compressive sensing by using OMP and designed wavelet filters offers good result for performance as compared to the existing wavelet filters.
