Invariant quadratic operator associated with Linear Canonical Transformations
Authors: Ranaivoson Ravo Tokiniaina , Andriambololona Raoelina , Hanitriarivo Rakotoson
Published: February 2021

The main purpose of this work is to identify the general quadratic operator which is invariant under the action of Linear Canonical Transformations (LCTs). LCTs are known in signal processing and optics as the transformations which generalize certain useful integral transforms. In quantum theory, they can be identified as the linear transformations which keep invariant the canonical commutation relations characterizing the coordinates and momenta operators. In this paper, LCTs corresponding to a general pseudo-Euclidian space are considered. Explicit calculations are performed for the monodimensional case to identify the corresponding LCT invariant operator then multidimensional generalizations of the obtained results are deduced. It was noticed that the introduction of a variance-covariance matrix, of coordinate and momenta operators, and a pseudo-orthogonal representation of LCTs facilitate the identification of the invariant quadratic operator. According to the calculations carried out, the LCT invariant operator is a second order polynomial of the coordinates and momenta operators. The coefficients of this polynomial depend on the mean values and the statistical variances-covariances of these coordinates and momenta operators themselves. The eigenstates of the LCT invariant operator are also identified with it and some of the main possible applications of the obtained results are discussed.

Introduction:

The aim of this study was to determine the relationship between blood glucose level and preoperative anxiety and postoperative pain in children undergoing adenotonsillectomy.
Material and methods

In this cross-sectional study 156 children undergoing adenotonsillectomy involved. Patients’ blood glucose levels were measured at different times. In order to assess the anxiety and restlessness of children, the Anxiety Scale of m-YPAS (Modified Yale Preoperative Anxiety Scale) was used. To evaluate the children’s postoperative pain, VAS (visual analog scale) was used before feeding after the surgery.
Results

Mean of patients’ blood glucose levels was (92.63 ± 9.33) 15 minutes before the surgery, (87.26 ± 8.32) 15 minutes after the surgery and (85.17 ± 1.3) before feeding after the surgery. The results showed no significant correlation between mean anxiety score and mean blood glucose level at different times. There was a significant correlation between mean pain score and blood glucose level measured 15 minutes after the surgery (p-value = 0.004) but showed no significant correlation 15 minutes before the surgery (p-value = 0.29) and also before feeding after the surgery (p-value = 0.240).
Conclusion

According to our results, since there was only a significant correlation between mean pain score and blood glucose level measured 15 minutes after the surgery (not between the other different times) and over time, due to the body's natural analgesic mechanisms this effect is reduced, it can be concluded that it is not rational to advise hyperglycemic solutions and serums containing glucose in children undergoing adenotonsillectomy.

ObjectiveThe Coronavirus Disease 2019 (COVID-19) pandemic continues to threaten the physical and mental health of people across the world. This study aimed to understand the psychological impact of this disease on adolescents with major depressive disorder (MDD) at one month after the start of the outbreak in China.MethodsUsing the Children's Impact of Event Scale (CRIES-13) questionnaire, we investigated the occurrence of posttraumatic stress disorder (PTSD) in two groups of adolescents: MDD patients who were in stable condition with antidepressant therapy and healthy controls. Total scores and factor subscores were compared between the two groups and subgroups stratified by sex and school grade. Logistic regression was used to identify variables associated with high total CRIES-13 scores.ResultsCompared to controls (n = 107), the MDD group (n = 90) had higher total CRIES-13 scores and a higher proportion with a total score ≥ 30. They also had a lower intrusion subscore and a higher arousal subscore. In the MDD group, males and females did not differ significantly in total CRIES-13 scores or factor subscores, but junior high school students had higher avoidance subscores than senior high school students. Logistic regression showed high total CRIES-13 scores to be associated with MDD and the experience of “flashbacks” or avoidance of traumatic memories associated with COVID-19.ConclusionsIt is crucial to understand the psychological impact of COVID-19 on adolescents with MDD in China, especially females and junior high school students. Long-term monitoring of adolescents with a history of mental illness is required to further understand these impacts.Trial registrationChiCTR, ChiCTR2000033402, Registered 31 May 2020, http://www.chictr.org.cn/index.aspx

Published: February 2021

BackgroundIn 2014, the terrorist militant group the Islamic State of Iraq and Syria (ISIS) took over one-third of Iraq. This study measured the rate of posttraumatic stress disorder (PTSD) among Iraqi internally displaced persons (IDPs) and examined associated demographic and traumatic risk factors and comorbid psychiatric symptoms.MethodsA cross-sectional survey was carried out in April-June 2015 at the Khanke camp, northern Iraq. Trauma exposure and PTSD were measured by the Harvard Trauma Questionnaire (Iraqi version), and psychiatric comorbidity was measured by the General Health Questionnaire (GHQ-28).ResultsOf 822 adult IDPs, 33.8% screened positive for PTSD. Associated factors included exposure to a high number of traumatic events, unmet basic needs and having witnessed the destruction of residential or religious areas. Being a widow was the only linked demographic factor (OR = 14.56, 95% CI: 2.93–72.27). The mean scores of anxiety/insomnia and somatic symptoms were above the average cutoff means (M = 3.74, SD = 1.98, R = 0–7 and M = 3.69, SD = 2.14, R = 0–7, respectively) among the IDPs with PTSD.ConclusionsHigh traumatic exposure, specifically unmet basic needs and having witnessed destruction, was an important predictor of PTSD among IDPs. Psychiatric comorbidity was high among those with PTSD. Anxiety, insomnia and somatic symptoms were strongly associated with PTSD. These findings are important for mental health planning for IDPs in camps.Clinical trial registrationNot applicable.

Authors: Liu Keyun , Sun Jia , Shao Lingling , He Hongwei , Liu Qinglin , Li Youxiang , Ge Huijian
Published: February 2021

Background and purpose: We investigated whether periodontal diseases, specifically, periodontitis and gingivitis, could be risk factors of the incidence of intracranial aneurysms (IAs).Methods: We performed a case–control study to compare the differences in the periodontal disease parameters of 281 cases that were divided into the IAs group and non-IAs group. All cases underwent complete radiographic examination for IAs and examination for periodontal health. Results: Comparing with those in the non-IAs group, the cases in the IAs group were older (53.95 ± 8.56 vs 47.79 ± 12.33, p < 0.001) and had a higher incidence of hypertension (76 vs 34, p = 0.006). Univariate logistic regression analysis revealed that age (>50 years) and hypertension were predictive risk factors of aneurysm formation (odds ratio [OR] 1.047, 95% confidence interval [95%CI] 1.022–1.073, p < 0.001 and OR 2.047, 95%CI 1.232–3.401, p = 0.006). In addition, univariate and multivariate logistic regression analyses showed that the parameters of periodontal diseases, including gingival index, plaque index, clinical attachment loss, and alveolar bone loss, were significantly associated with the occurrence of IAs (all p < 0.05). For further statistical investigation, the parameters of periodontal diseases were divided into four layers based on the quartered data. Poorer periodontal health condition (especially gingival index＞1.1 and plaque index＞1.5) had the correlation with IAs formation (p＝0.007 and p＜0.001). Conclusion: Severe gingivitis or periodontitis combining with hypertension, are significantly associated with the incidence of IAs.
Does the gap between health workers’ expectations and the realities of implementing a Performance-Based Financing project in Mali create frustration?

Published: February 2021

Background: Performance-Based Financing (PBF), an innovative health financing initiative, was recently implemented in Mali. PBF aims to improve quality of care by motivating health workers. The purpose of this research was to identify and understand how health workers’ expectations related to their experiences of the first cycle of payment of PBF subsidies, and how this experience affected their motivation and sentiments towards the intervention. We pose the research question, “how does the process of PBF subsidies impact the motivation of health workers in Mali?”Methods: We adopted a qualitative approach using multiple case studies. We chose three district hospitals (DH 1, 2 and 3) in three health districts (district 1, 2 and 3) among the ten in the Koulikoro region. Our cases correspond to the three DHs. We followed the principle of data source triangulation; we used 53 semi-directive interviews conducted with health workers (to follow the principle of saturuation), field notes, and documents relating to the distribution grids of subsidies for each DH. We analyzed data in a mixed deductive and inductive manner.Results: The results show that the PBF subsidies led to health workers feeling more motivated to perform their tasks overall. Beyond financial motivation, this was primarily due to PBF allowing them to work more efficiently. However, respondents perceived a discrepancy between the efforts made and the subsidies received. The fact that their expectations were not met led to a sense of frustration and disappointment. Similarly, the way in which the subsidies were distributed and the lack of transparency in the distribution process led to feelings of unfairness among the vast majority of respondents. The results show that frustrations can build up in the early days of the intervention.Conclusion: The PBF implementation in Mali left health workers frustrated. The short overall implementation period did not allow actors to adjust their initial expectations and motivational responses, neither positive nor negative. This underlines how short-term interventions might not just lack impact, but instil negative sentiments likely to carry on into the future.
La fixation du loyer contesté : une jurisprudence à bout de souffle ?

Published: February 2021

L’auteur donne son point de vue propos d’un arrêt du tribunal fédéral qui a suscité beaucoup d’interrogations de la part des spécialistes du droit du bail à loyer. En raison de la baisse constante des taux des intérêts hypothécaires, nos juges suprêmes abandonnent leurs vieilles jurisprudences de 1994 et 1986 sur la réévaluation des fonds propres et sur le taux d’intérêt qu’il convient d'appliquer à ces derniers dans le calcul de rendement au sens de l’art. 269 CO. De l’avis de Lachat ces revirements de jurisprudence ne convainquent pas et souffrent d’un manque de motivation. L’auteur invite milieux concernés à s’asseoir autour d'une table de négociations, sous les auspices des autorités politiques, et à trouver des solutions à inscrire dans l’ordonnance (OBLF) d’application des art. 253 à 273c CO.

Published: February 2021

This literature review aimed to describe the opportunities and challenges of integrating the Learning Management System (LMS) in mathematics learning, especially in terms of the non-technical aspects. Because many LMS platforms which can be integrated into learning process, this review only discusses the three LMS platforms which are common, namely Moodle, Edmodo, and Schoology. This review was conducted with the method as proposed by Templier and Paré (2015), in which the literature materials consisted of journal articles, proceedings, and official websites of LMS. The results of this review showed that integrating the LMS in mathematics learning indicated opportunities in terms of the positive impact which can be obtained from integrating the LMS. On the other hand, the identified challenges were about how mathematics content or materials were organized through integrating the LMS, providing feedback, and maximizing the online discussion facility provided by LMS. Therefore, to obtain the positive impact from integrating the LMS into mathematics learning, teachers should pay attention to these three challenges.

Published: February 2021

Las/os enfermeras/os desarrollan una actividad laboral centrada en el cuidado de los otros. Esta labor es fuente de satisfacción, pero también ha implicado niveles importantes de fatiga y deterioro en su calidad de vida. El propósito del presente estudio fue establecer los predictores de calidad de vida relacionada a la compasión en enfermeras/os de hospitales públicos de La Paz y El Alto, Bolivia. Para ello se consideraron como predictores la sobrecarga del cuidador, el burnout y características sociolaborales. Participaron 500 enfermeras/os de cuatro hospitales, de los cuales 82,4 % fueron mujeres, con un rango de edad de entre 21 y 61 años. Se utilizó un diseño no-experimental de tipo descriptivo y correlacional, y de corte transversal. Se encontró que el factor de burnout de agotamiento emocional, la sobrecarga del cuidador y el hecho de tener hijos predicen negativamente la calidad de vida relacionada a la compasión. Además, se observó una correlación negativa del agotamiento emocional con la edad y los años de experiencia laboral. Se discute sobre la necesidad de otorgar mejores condiciones laborales que alivien el desgaste, faciliten la interacción trabajo-familia y promuevan una mejor calidad de vida en enfermeras/os.

Published: February 2021

La cifra de personas que presentan o han presentado alguna conducta suicida ha aumentado significativamente en Colombia desde el año 2014 al 2019, convirtiendo la conducta suicida en una problemática de salud pública; sin embargo, es un concepto amplio, que abarca diferentes tipos de conductas, por esto es necesario establecer un protocolo de atención para estandarizar las acciones del terapeuta o personas que se desempeñan en los servicios prestadores de salud. El presente artículo tiene como objetivo describir cómo se realizó el diseño y la validación de un protocolo de atención psicológica para atención en ideación suicida de los consultantes que asisten a un centro de atención psicológica de una institución universitaria de la ciudad de Bogotá. Se realizó un estudio cuantitativo, de tipo instrumental, el cual implicó: a) el diseño de la ruta de atención, situaciones que activan el protocolo y el módulo de atención en crisis; b) la participación de 10 jueces expertos con el fin de realizar la validación por contenido de todos los componentes del protocolo de atención psicológica. Los resultados arrojaron que el diseño es pertinente, suficiente y relevante para la problemática que se buscó abordar.
Efecto de las experiencias adversas durante la niñez sobre la actividad electroencefalográfica en reposo
Authors: Sereno Torres Liliana Camila , Camelo Roa Sandra Milena
Published: February 2021

El progresivo interés en estudiar los efectos negativos en la fisiología y estructura cerebral producto de las experiencias adversas durante la niñez (EAN) ha propiciado el análisis de registros psicofisiológicos por medio de la electroencefalografía (EEG) en estados de reposo. Por tanto, el objetivo de este estudio permitió realizar una revisión sistemática basada en la metodología PRISMA para identificar las investigaciones adelantadas en los últimos 30 años. Para ello se utilizaron cuatro bases de datos: Scopus, PubMed, EBSCO y Redalyc; y dos listas de términos referentes a los tipos de EAN prevalentes en Colombia y al EEG en reposo. Inicialmente, se encontraron 21 556 artículos que contaron con los términos de búsqueda; se excluyeron 21 545 estudios que no cumplían con los criterios, y, finalmente, se seleccionaron 11 artículos de texto completo. Los resultados sugieren que la actividad de las bandas alfa α frontales derechas predicen mayor respuesta emocional a estímulos negativos, y mayor probabilidad de presentar problemas afectivos; contrario a la actividad electroencefalográfica en estas mismas bandas en regiones frontales izquierdas. Se espera que este estudio promueva investigaciones relacionadas con el análisis de perfiles electroencefalográficos y favorezca el avance de procesos terapéuticos más precisos y eficaces en la intervención del trauma.
Understanding equity repurchase motives for different firm set-up: Indian evidence
Authors: Bhama Vandana
Published: February 2021

Corporates express their intention to reward shareholders during repurchase announcements by maximizing their wealth. However, most empirical research finds that stocks’ performance is poor when repurchase announcements are made, and there are no significant abnormal returns. In the Indian context, the present study examines firms’ real intention behind repurchase decisions. The sample comprises 132 firms listed on the Bombay Stock Exchange (BSE) from 2012 to 2018. A Tobit regression model has been used on different firm set-up. The empirical results reveal that low stock valuation is the prominent reason for buybacks among corporates. Firms prefer repurchases to provide abnormal returns to the investors; however, the Indian market does not react much positively to the repurchases, and this might be the reason for less encouraging buybacks in the Indian market. Further, the tender offer is the most preferred mode to open market repurchases. In the case of service firms, undervaluation, low earnings, and low debt ratios are the contributing factors impacting repurchases. Firms with low dividend intend to have more buybacks to reduce their tax burden.

Published: February 2021

Implementing performance management systems, including the KPI (Key Performance Indicators) system, at the university level faces many difficulties. The study aims to determine the problems of formation and implementation of the system of KPIs at the HEIs (higher education institutions) level based on the case study. Methodologically the study is based on the analysis of the case of the KPI system implementation at Vasyl’ Stus Donetsk National University (Ukraine) using a 3-year project survey of managers and employees of structural units about self-analysis of deviations and perception of each performance indicator. The essential subjective factor – irrational participants’ behavior – is demonstrated, reflected in their resistance, fear, and lack of acceptance of innovations in assessment processes, which needs to delineate tools for effective KPI system implementation (reduction of its negative influence and growth of the personnel loyalty). The main organizational obstacles that reduce such a measurement system’s efficiency are incomprehensibility, difficulty of evaluation, non-influence or independency of indicators from the efforts of respondents, poor communication, and motivation to achieve them. The analysis results allowed providing the recommendations that could contribute to the formation of reflexive and active management culture in the strategic management system and a culture of productive dialogue through vertically and horizontally management interaction.

Authors: Bokings Surya Hidayat , Nurmandi Achmad , Loilatu Mohammad Jafar
Published: February 2021

The research focuses on using social media (Twitter) as a medium for public transportation services (Bus Rapid Transit - BRT) in Semarang and Jakarta. The research uses Nvivo 12 Plus as a tool in qualitative research methods. The results show that the function regarding Twitter accounts of BRT in Semarang and Jakarta has several differences. The difference is based on information integration services, interaction information and transparency, and adaptive and responsive information services. In conclusion, the information integration on Twitter accounts of BRT in Semarang and Jakarta services works well, but a more dominant function is found in BRT in Jakarta. The Twitter account of BRT in Jakarta provides more information on transportation routes, such as the number of routes and fleets. BRT in Jakarta is a responsive account, responding to questions or mentions given by its users. The high level of activity makes the BRT Jakarta account more active. Moreover, the form of information conveyed by the Twitter account of BRT Semarang has its characteristics because it shows more the character of the region (Central Java).
Spatially Filtered Ridge Regression Modeling to Find Out the Rice Production Factors in East Java, Indonesia
Authors: Islami Vita Dewi , Fitriani Rahma , Pramoedyo Henny
Published: February 2021

The research aims to model rice production in East Java using the Spatially Filtered Ridge Regression (SFRR) method and ensure that all violations of assumptions are resolved by knowing the direct and indirect effect of predictor variables. The data are secondary data sourced from the publication of Badan Pusat Statistik containing provincial food crop agriculture statistics in East Java and the 2018 publication of Dinas Pertanian Jawa Timur (literally translated as Agriculture Department of East Java). The data analysis process is done by RStudio and ArcMap 10.3 software. In the research, the observation unit is 38 regencies or cities in East Java. The analysis results show that SFRR with queen contiguity weighting can overcome spatial autocorrelation and multicollinearity in rice production data in East Java. As for the established model, the variables of rice field area, urea fertilizer, Phonska fertilizer, SP-36 fertilizer, and tractor have a significant effect on rice production. However, ZA fertilizer has no significant effect on rice production. Then, a large comparison of direct and indirect impacts for each predictor variable is also generated. Generally, direct impacts are greater than indirect impacts.
Comparative Advantage of Using Bio-pesticides in Indian Agro-ecosystems

Published: February 2021

The use of unsustainable levels of plant protection chemicals and fertilizershas resulted in a steady decline in soil quality and crop productivity the world over. To combat this decline, agricultural practices must evolve to meet the growing global demand for food without irreversibly damaging the world’s natural resources.Biopesticides have tremendous potential to bring sustainability to agriculture and environmental safety.This article is part of a larger study conducted in India by the authors at theUniversité de Montréal with the support of Mitacs and Earth Alive Clean Technologies. In this research, farmers, manufacturers or suppliers of biopesticides, and R&D scientistswere interviewed, and their responses demonstratethe advantages of applyingmicrobial biopesticidesto field crops. Participants reported a15-30% increase in yields and crop production after the application ofbiopesticides, with better quality and quantity of fruits, grains, and tubers with a longer shelf life. Moreover, while the risk of croploss is high (60-70%) with chemicallygrown crops, this risk is reduced to 33% on average when crops are grown using biopesticides. The risk of crop loss is thus considerably reducedby the use ofbiopesticides.Yet, despite their positive impact on the health of humans, soil,ecosystems, andfriendly invertebrates,biopesticides face significant challenges and competition vis-à-vis synthetic pesticides for a variety of reasons. The development of biopesticides must overcome the problems of improper formulations, short shelf life, delayed action, and high market costs, as well as a variety oflegal/registration issues.

Published: February 2021

O presente artigo inicia apresentando a trajetória das Universidades desde o surgimento no período medieval, com a criação de uma comunidade de scolares; passando pelo fenômeno da nacionalização, com a consequente perda do seu caráter inicial influenciado pelas escolas de ofício e posteriormente pela ordem eclesiástica e imperial; abordando nesse bojo o processo de estatização a partir da revolução francesa. A universidade brasileira, fortemente influenciada até a década de 1970 pelo modelo europeu, foi impactada pelas premissas das reformas educacionais e objetivos delineados para uma estrutura integradora entre ensino e pesquisa, que ocorreu de forma mais efetiva a partir da década de 1980, movimento apresentado juntamente com as iniciativas de internacionalização da universidade. Por último, são elencadas as estratégias para o desenvolvimento de um projeto de internacionalização das universidades brasileiras no século XXI sob a premissa de que para conceber a cooperação internacional, como parte integrante das missões institucionais, cabe às universidades a criação de mecanismos e estruturas apropriadas para promover a internacionalização como um dos pressupostos indicativos desse direcionamento.
Estudo relacional entre gênero e rendimento escolar de alunos do Ensino Fundamental e Médio de Brasília-Brasil
Authors: Sanches Eder Angelo , Ulloa Oscar
Published: February 2021

Este estudo se propõe descobrir relações entre gênero e rendimento escolar, composto em especial por valores de metas acadêmicas (3 fatores psicossociais não-cognitivos), de uma amostra de alunos de 11 a 17 anos inseridos na rede de ensino fundamental II e médio de Brasília-DF, capital do Brasil. A pesquisa se inscreveu em uma perspectiva motivacional, que se sustenta em um desenho transversal descritivo e correlacional com metodologia qualitativa e quantitativa. Se aplicou o Questionário de Metas Acadêmicas de Hayamizu e Weiner (1991). Descreveu-se e aplicou, empiricamente, a um grupo de alunos dos gêneros masculino e feminino. Foi possível demonstrar que não existiram correlações entre as variáveis devido à normalidade estatística da amostra. No entanto, os resultados da descrição fazem supor impactos positivos em metas de aprendizagem e metas de obtenção, pelo alto nível de pontuação obtido na descrição da amostra e pela consistência dos dados, e impactos negativos em metas de reforço social. O fato mais chamativo foi a contradição encontrada com os resultados obtidos por Cominetti e Ruiz (1997), que se baseiam em sustentar que o fator gênero ajuda a modular as relações com o rendimento escolar. Esta pesquisa contribui cientificamente com novos elementos às literaturas sobre o assunto.

Published: February 2021

São problemáticas que envolvem currículo, gênero e livros didáticos que tomamos como interesse de investigação neste artigo. Analisamos aqui como a categoria gênero é construída nos critérios de inclusão ou exclusão em editais do Programa Nacional do Livro Didático. Algumas vezes, gênero é abarcado em critérios de cidadania ou Direitos Humanos. Outras, vem explicitamente associado à mulher e relacionado ao que é construído sobre feminino e masculino. Para empreender as análises, observamos os documentos legais reguladores do PNLD, além dos editais do período de 2006 a 2020, disponíveis para consulta eletrônica. Com as análises, percebemos o caráter geral e pouco característico dos itens avaliativos sobre questões de diversidade de gênero, que, além de estar em reduzidos itens, compartilham espaço com outras categorias analíticas, como raças e etnias. Tal avaliação, a depender do posicionamento político em relação à temática, acarreta, portanto, em silenciamentos ou aprisionamentos de gênero nas coleções de LD.
Budizm’in Misyon Anlayışının Temelleri
Authors: Kaya Murat
Published: February 2021

Budizm misyoner bir dindir. Onun misyon anlayışı, Buda tarafından belirlenmiş, ondan sonraki misyon faaliyetleri de Buda’nın uygulamaları doğrultusunda gerçekleşmiştir. Budizm’in misyon faaliyetleri başlangıçta Hindistan ile sınırlı kalmış, uzun bir bekleyiş ve gelişim sürecinden sonra Hindistan dışına çıkmıştır. Keşişlerin yoğun gayretleri sayesinde önemli başarılar elde eden Budizm, gittiği ülkelerde dini, siyasi ve sosyal yapıyı derinden etkilemiştir. Kapsayıcı bir yaklaşımı benimseyen Budizm, karşılaştığı dinleri bünyesine katarak büyümüştür. Bu yaklaşımı sebebiyle, miladi bin yılına gelindiğinde, Asya’nın birçok ülkesine yayılmış bir din haline gelmiştir. Bu özellikleri nedeniyle bu çalışmada, Budizm’in misyon anlayışı ele alınmıştır. Çalışma, Budizm’in öğretileri, ortaya çıkışı ve misyon anlayışı olmak üzere üç bölüme ayrılmış; sonuç olarak devlet yöneticilerine hitap, esnek öğreti ve manastır hayatının Budizm’in misyon anlayışının temellerini oluşturduğu düşüncesine varılmıştır.

Published: February 2021

The study investigated the extent of relationship of the agriculture industry concentration and growth of Philippine agriculture. Specifically, it determined the key agriculture sub-sectors in each region in the Philippines and investigated the regional industry concentration and economic performance nexus. The objectives were achieved using secondary data for the 16 regions in the Philippines. Location Quotient (LQ) and correlation analysis were used as tools to make sense of the data. Results show a number of key industries in each region which from the assumptions of the LQ formed the economic base of the region. The findings show non-significant correlation between regional industry concentration and the GVA for agriculture. This suggested for further investigation of the concentration or diversity relationship to economic performance.

Dopamine is an important neurotransmitter belonging to the catecholamine family, which acts on the central nervous system. This catecholamine plays a key role in regulating a variety of functions, such as motor and cognitive functions. This class of neurotransmitters is important for normal neurophysiology and is also the target of a broad spectrum of therapeutic and illicit agents. Evaluating the interaction of these neurotransmitters, in particular, dopamine with water molecules, is crucial for a better understanding of the conformational preferences of dopamine in solution, which consequently assists in the design of new drugs for the treatment of diseases associated with a malfunction of the system, and direct measurement, which is particularly essential for early warning of certain diseases. In this sense, the objective of this work is to examine the effects of aqueous solvation on the geometric and electronic parameters of dopamine using Car-Parrinelo Molecular Dynamics. The Car-Parrinello Molecular Dynamics simulation was performed using the CPMD program package (Version 4.1). The results indicate that dopamine interact swith several water molecules, with the formation of hydrogen bonds. In particular, there are two hydrogen bonds (H5···Owf and N3···Hwd) with an infinite residence time that strongly suggests the protonation of these groups.

Published: February 2021

Background

Patients can struggle to make good use of psychotherapy owing to deficits in awareness, and digital technologies that support awareness are at a premium. Currently, when patients participate in cognitive analytic therapy (CAT), the technology supporting relational awareness work involves completion of paper-based worksheets as between-session tasks.

Objective

We aimed to design, with therapists and patients, a prototype digital mobile app. This was to help patients better engage in the “recognition” phase of the CAT treatment model by providing an unobtrusive means for practicing relational awareness with dynamic feedback on progress.

Methods

A national online survey was conducted with CAT therapists (n=50) to determine readiness for adoption of a mobile app in clinical practice and to identify core content, functionality, and potential barriers to adoption. A prototype mobile app based on data and existing paper-based worksheets was built. Initial face-to-face user testing of the prototype system was completed with three therapists and three CAT expatients.

Results

Among the therapists surveyed, 72% (36/50) reported not currently using any digital tools during CAT. However, the potential value of a mobile app to support patient awareness was widely endorsed. Areas of therapist concern were data security, data governance, and equality of access. These concerns were mirrored during subsequent user testing by CAT therapists. Expatients generated additional user specifications on the design, functionality, and usability of the app. Results from both streams were integrated to produce five key changes for the reiteration of the app.

Conclusions

The user-centered design process has enabled a prototype CAT-App to be developed to enhance the relational awareness work of CAT. This means that patients can now practice relational awareness in a much more unobtrusive manner and with ongoing dynamic feedback of progress. Testing the acceptability and feasibility of this technological innovation in clinical practice is the next stage in the research process, which has since been conducted and has been submitted. The important challenges of data protection and governance must be navigated in order to ensure implementation and adoption if the CAT-App is found to be acceptable and clinically effective.
Consumer-Based Activity Trackers as a Tool for Physical Activity Monitoring in Epidemiological Studies During the COVID-19 Pandemic: Development and Usability Study (Preprint)
Authors: Henriksen André , Johannessen Erlend , Hartvigsen Gunnar , Grimsgaard Sameline , Hopstock Laila Arnesdatter
Published: February 2021

BACKGROUND

Consumer-based physical activity trackers have increased in popularity. The widespread use of these devices and the long-term nature of the recorded data provides a valuable source of physical activity data for epidemiological research. The challenges include the large heterogeneity between activity tracker models in terms of available data types, the accuracy of recorded data, and how this data can be shared between different providers and third-party systems.

OBJECTIVE

The aim of this study is to develop a system to record data on physical activity from different providers of consumer-based activity trackers and to examine its usability as a tool for physical activity monitoring in epidemiological research. The longitudinal nature of the data and the concurrent pandemic outbreak allowed us to show how the system can be used for surveillance of physical activity levels before, during, and after a COVID-19 lockdown.

METHODS

We developed a system (mSpider) for automatic recording of data on physical activity from participants wearing activity trackers from Apple, Fitbit, Garmin, Oura, Polar, Samsung, and Withings, as well as trackers storing data in Google Fit and Apple Health. To test the system throughout development, we recruited 35 volunteers to wear a provided activity tracker from early 2019 and onward. In addition, we recruited 113 participants with privately owned activity trackers worn before, during, and after the COVID-19 lockdown in Norway. We examined monthly changes in the number of steps, minutes of moderate-to-vigorous physical activity, and activity energy expenditure between 2019 and 2020 using bar plots and two-sided paired sample t tests and Wilcoxon signed-rank tests.

RESULTS

Compared to March 2019, there was a significant reduction in mean step count and mean activity energy expenditure during the March 2020 lockdown period. The reduction in steps and activity energy expenditure was temporary, and the following monthly comparisons showed no significant change between 2019 and 2020. A small significant increase in moderate-to-vigorous physical activity was observed for several monthly comparisons after the lockdown period and when comparing March-December 2019 with March-December 2020.

CONCLUSIONS

mSpider is a working prototype currently able to record physical activity data from providers of consumer-based activity trackers. The system was successfully used to examine changes in physical activity levels during the COVID-19 period.
Comparison of anti-microbial efficacy of Calcipex and Metapex in endodontic treatment of chronic apical periodontitis (Preprint)

Published: February 2021

BACKGROUND

Various intracanal medicaments have been used in cases of chronic apical periodontitis for appropriate disinfection of the root canal system to eliminate microbes specially from the inaccessible areas. Caclcium Hydroxide (CH) is the most common intracanal medicament available in various forms, but its effectiveness with or without iodoform using microbial culture is unknown.

OBJECTIVE

To compare the anti-microbial efficacy of Calcipex and Metapex in endodontic treatment of teeth presenting with chronic apical periodontitis

METHODS

60 single rooted teeth of patients with diagnosis of chronic apical periodontitis were selected and the canals were debrided chemo-mechanically. The patients were randomized into two groups: Calcipex and Metapex. The first sample (S1) for bacterial culture was taken before placement of intracanal medicament and the second sample (S2) was taken after 7 days, before final obturation from the canal and sent to lab for culture. Colony Forming Unit (CFU) will be evaluated.
Paired t-test will be used to assess difference bet¬ween antimicrobial efficacies within the group of medicaments. Independent sample t-test will be used to assess antimicrobial efficacies between groups. Level of significance will be kept at 0.05.

RESULTS

The results wil be shared upon completion of study.

CONCLUSIONS

There is no risk involved in this study as the study is based on routine procedure of endodontic treatment. It will be a benefit for future patients which will help us to decide which intracanal medicament is more effective to use in infected canals.

Validation of the Withings ScanWatch as a Wrist-Worn Reflective Pulse Oximeter: Prospective Interventional Clinical Study (Preprint)
Authors: Kirszenblat Romain , Edouard Paul
Published: February 2021

BACKGROUND

A decrease in the level of pulse oxygen saturation as measured by pulse oximetry (SpO2) is an indicator of hypoxemia that may occur in various respiratory diseases, such as chronic obstructive pulmonary disease (COPD), sleep apnea syndrome, and COVID-19. Currently, no mass-market wrist-worn SpO2 monitor meets the medical standards for pulse oximeters.

OBJECTIVE

The main objective of this monocentric and prospective clinical study with single-blind analysis was to test and validate the accuracy of the reflective pulse oximeter function of the Withings ScanWatch to measure SpO2 levels at different stages of hypoxia. The secondary objective was to confirm the safety of this device when used as intended.

METHODS

To achieve these objectives, we included 14 healthy participants aged 23-39 years in the study, and we induced several stable plateaus of arterial oxygen saturation (SaO2) ranging from 100%-70% to mimic nonhypoxic conditions and then mild, moderate, and severe hypoxic conditions. We measured the SpO2 level with a Withings ScanWatch on each participant’s wrist and the SaO2 from blood samples with a co-oximeter, the ABL90 hemoximeter (Radiometer Medical ApS).

RESULTS

After removal of the inconclusive measurements, we obtained 275 and 244 conclusive measurements with the two ScanWatches on the participants’ right and left wrists, respectively, evenly distributed among the 3 predetermined SpO2 groups: SpO2≤80%, 80%<SpO2≤90%, and 90%<SpO2. We found a strong association and a high level of agreement between the measurements collected from the devices, with high Pearson correlation coefficients of r=0.944 and r=0.954 on the correlation plots, low Pearson correlation coefficients of r=0.083 (P=.17) and r=0.23 (P=.001) on Bland-Altman plots, biases of 0.98% (95% CI 0.65-1.32) and 1.56% (95% CI 1.24-1.87), and root mean square errors of 2.97% and 3.00% from the participants’ right and left hands, respectively.

CONCLUSIONS

In conclusion, the Withings ScanWatch is able to measure SpO2 levels with adequate accuracy at a clinical grade. No undesirable effects or adverse events were reported during the study.
