Reliability of Commercial Voice Assistants’ Responses to Health-Related Questions in Noncommunicable Disease Management: Factorial Experiment Assessing Response Rate and Source of Information
Authors: Bérubé Caterina , Kovacs Zsolt Ferenc , Fleisch Elgar , Kowatsch Tobias 
Published: November 2021

Background
Noncommunicable diseases (NCDs) constitute a burden on public health. These are best controlled through self-management practices, such as self-information. Fostering patients’ access to health-related information through efficient and accessible channels, such as commercial voice assistants (VAs), may support the patients’ ability to make health-related decisions and manage their chronic conditions.

Objective
This study aims to evaluate the reliability of the most common VAs (ie, Amazon Alexa, Apple Siri, and Google Assistant) in responding to questions about management of the main NCD.

Methods
We generated health-related questions based on frequently asked questions from health organization, government, medical nonprofit, and other recognized health-related websites about conditions associated with Alzheimer’s disease (AD), lung cancer (LCA), chronic obstructive pulmonary disease, diabetes mellitus (DM), cardiovascular disease, chronic kidney disease (CKD), and cerebrovascular accident (CVA). We then validated them with practicing medical specialists, selecting the 10 most frequent ones. Given the low average frequency of the AD-related questions, we excluded such questions. This resulted in a pool of 60 questions. We submitted the selected questions to VAs in a 3×3×6 fractional factorial design experiment with 3 developers (ie, Amazon, Apple, and Google), 3 modalities (ie, voice only, voice and display, display only), and 6 diseases. We assessed the rate of error-free voice responses and classified the web sources based on previous research (ie, expert, commercial, crowdsourced, or not stated).

Results
Google showed the highest total response rate, followed by Amazon and Apple. Moreover, although Amazon and Apple showed a comparable response rate in both voice-and-display and voice-only modalities, Google showed a slightly higher response rate in voice only. The same pattern was observed for the rate of expert sources. When considering the response and expert source rate across diseases, we observed that although Google remained comparable, with a slight advantage for LCA and CKD, both Amazon and Apple showed the highest response rate for LCA. However, both Google and Apple showed most often expert sources for CVA, while Amazon did so for DM.

Conclusions
Google showed the highest response rate and the highest rate of expert sources, leading to the conclusion that Google Assistant would be the most reliable tool in responding to questions about NCD management. However, the rate of expert sources differed across diseases. We urge health organizations to collaborate with Google, Amazon, and Apple to allow their VAs to consistently provide reliable answers to health-related questions on NCD management across the different diseases.

Authors: Economides Marcos , Bolton Heather , Male Rhian , Cavanagh Kate 
Published: November 2021

Background
There is growing interest in digital platforms as a means of implementing scalable, accessible, and cost-effective mental health interventions in the workplace. However, little is known about the efficacy of such interventions when delivered to employee groups.

Objective
This study aims to evaluate the feasibility and preliminary efficacy of a digital mental health platform for the workplace, which incorporates evidence-based practices such as cognitive behavioral therapy and acceptance and commitment therapy. A total of 3 brief, unguided interventions designed to address stress, anxiety, and resilience, respectively, are evaluated. The primary aim is to determine the feasibility of the study methods and interventions in preparation for a definitive randomized controlled trial.

Methods
The study used a fully remote, parallel, multi-arm, external pilot randomized controlled trial, with 3 intervention arms and a no-intervention control group. Participants were working adults representative of the general UK population with respect to age, sex, and ethnicity who were recruited from a web-based participant platform. Primary outcomes included objective and self-report measures of feasibility, acceptability, engagement, transferability, relevance, and negative effects. Secondary outcomes included 4 self-report measures of mental health and well-being, completed at baseline (time point 0 [t0]), postintervention (time point 1 [t1]), and the 1-month follow-up (time point 2 [t2]). Secondary outcomes were analyzed via linear mixed-effects models using intention-to-treat principles. Preregistered criteria for progression to a definitive trial were evaluated.

Results
Data were collected between January and March of 2021. A total of 383 working adult participants meeting trial eligibility were randomized, of whom 356 (93%) were retained at t2. Objective engagement data showed that 67.8% (196/289) of participants randomized to an intervention arm completed their intervention. Overall, 87.1% (203/233) of participants reported being satisfied or very satisfied with their intervention and rated the quality of their intervention as good or excellent. All intervention groups reported significantly greater improvements than the control group on at least one secondary outcome at t1, with between-group Hedges g effect sizes for the pooled interventions ranging from 0.25 (95% CI 0.05-0.46) to 0.43 (95% CI 0.23-0.64). All the improvements were maintained at t2.

Conclusions
The study methods were feasible, and all preregistered criteria for progression to a definitive trial were met. Several minor protocol amendments were noted. Preliminary efficacy findings suggest that the study interventions may result in improved mental health outcomes when offered to working adults.

Published: November 2021

Se evaluó la actividad de biodegradación de microrganismos en la recuperación de suelos contaminados por hidrocarburos. Se usaron dos concentraciones de hidrocarburos totales de petróleo (TPH) iniciales: 4,7 % y 6.5% a los cuales se aplicó microorganismos degradadores de hidrocarburos (MDH) y microorganismos degradadores de fenoles (MDF). Se empleó diseño experimental factorial 2x2 con dos repeticiones, los tratamientos fueron T1: Suelo con TPH 4,7% + MDH, T2: Suelo con TPH 4,7% + MDH/MDF, T4: Suelo con TPH 6,5% + MDH, T5: Suelo con TPH 6,5% + MDH/MDF y dos testigos T3: Suelo con TPH 4,7% y T6: Suelo con TPH 6,5% sin aplicación de MD. La cantidad de microorganismos aplicada por tratamiento correspondió con la relación de 0,3% en peso del suelo a remediar. A cada uno se agregó suplemento nutricional tripo1ifosfato de sodio y urea 46%. La unidad experimental fueron bandejas plásticas con capacidad de 10 kg c/u de suelo contaminado. Los bioensayos se llevaron a cabo durante 62 días. Los resultados mostraron que el porcentaje de remoción fue mayor en T1: Suelo con TPH 4,7% + MDH y T4: Suelo con TPH 6,5% + MDH con 68% y 66% respectivamente. La utilización de la mezcla Degradador de hidrocarburos (MDH) + Degradador de Fenoles (MDF) en cuanto a % de remoción fue mayor para T2: Suelo con TPH 4,7% + MDH/MDF con un 65%. La prueba LSD Fisher (0.05) determinó diferencias significativas para concentraciones de hidrocarburos A (4,51) y B (6,51) con promedios de 1,60 TPH y 2,52 TPH respectivamente, lo que significa, a menor concentración inicial de TPH, mayor eficiencia de los microorganismos biodegradadores aplicados.

Published: November 2021

Timber harvesting is an activity in producing wood to supply the lumber industry. However, timber harvesting brought consequences such as decreasing carbon sequestration potential of natural forests. This study aimed to determine the reduction in the potential for carbon sequestration due to timber harvesting in natural forests. Data were collected using non-destructive methods through stand inventory before felling for all tree species, cruising results report, and tree distribution maps. Biomass was calculated using the existing allometric, and carbon stocks were calculated using the Intergovernmental Panel on Climate Change method. The results showed that there were 238 trees (65.29 m3) of stands in the study area (6 ha) based on stand inventory before felling. Potential biomass and carbon storage before trees felling were 16.12 ton ha-1 and 7.58 ton ha-1, respectively. Potential biomass and carbon storage after tree felling were 5.15 ton ha-1 and 2.42 ton ha-1, respectively. Carbon absorption before and after tree felling is 28.37 ton CO2eq ha-1 and 4.44 ton CO2eq ha-1, respectively. Carbon emissions during tree felling was 18.93 ton CO2eq ha-1 (81.00%). The application of environmentally friendly wood harvesting shall be carried out appropriately to minimize a decrease in carbon absorption from timber harvesting.

Loquat (Eriobotrya japonica) has a great potential to be cultivated as a fruit crop in North Sumatra. In order to cultivate loquat, the availability of high-quality seedlings is becoming an essential factor. This research was aimed to determine the response of loquat’s seed, stem, and shoot cutting on various types of medium. The seed, stem, and shoots cutting of loquat were collected from North Sumatra. Three types of medium, i.e., humus + roasted rice husk (1:1), raw rice husk + sand (1:1), and humus + raw rice husk (1:1), were used during the experiment in Cibodas Botanical Garden. The results show that the highest percentage of seed germination on the 10th week after the plantation was humus + roasted rice husk (91.18%) and followed by humus + raw rice husk (77.78%) and raw rice husk + sand (69.44%). The combination of humus + roasted rice husk gave a significant effect on plant high (9.178a cm), the number of leaves (5.51a), length of leaves (8.36a), and width of leaves (3.78a) on the 12th week after plantation. Moreover, there were no significant differences between shoot cutting and stem cutting propagation on parameters survival rate and the number of buds.

Cibodas Botanic Gardens (CBG) shall keep performing botanical exploration and ex situ conservation as part of the effort to rescue tropical montane rainforest plants, which tend to decrease in their natural habitat. Pasir Banteng and Pasir Pogor, Mount Gede Pangrango, were selected due to the potential threat and limited information on plants collected from these sites. The objectives of this study were to collect valuable plants, which have a conservation value and explore their potential usefulness. The study has begun by establishing a list of collectible plants. Then, the field activities were conducted by a plant collection explorative method along the hiking route, from 750 to 1,500 m asl, low-mid mountain as height as CBG, with no specific sampling point (found and collected). These plants have field treatment, were delivered to CBG, and would later be maintained in the garden. The study has obtained 31 species collected from Pasir Banteng and 20 species from Pasir Pogor. There were 35 families, with Orchidaceae being the most collectible. Some crucial findings were nine species included as least concern (LC) and a species as endangered (EN), based on their conservation status. At least six new species were identified as the garden enrichment of the CBG. In addition, at least fifteen species have potential utilization as construction materials, 29 species as ornamental plants, twelve species as medicinal plants, and some plants possessing multi-utilization. The results were significant in adding the collection’s richness and enhancing the conservation value of the plants conserved by CBG. It was also contributed to describing the plant species information of these sites.

Long jack (Eurycoma longifolia) is a medicinal plant that has become a common target for exploitation, leading to a population decline in natural forests. This study aimed to determine the stand structure and regeneration status of E. longifolia tree habitat in Batang Lubu Sutam Forest, Padang Lawas, North Sumatra. The research was performed through vegetation analysis using a purposive sampling technique with a randomized sample plot based on the presence of E. longifolia. A total of 181 plots were established in this study. The results showed that the horizontal structure of tree species in the research area had an inverted J-shape pattern, indicating that the number of trees decreased as the diameter increased. The vertical structure showed that all strata were found in the research location, dominated by stratum C. This condition indicated that the forest was in good condition. The regeneration status of 48 species in the location showed different categories. Thirty species (62.50%) were classified as good regeneration, ten species (18.75%) as new regeneration, and four species (8.30%) as poor and no regeneration. The high proportion of trees with good regeneration showed that the forest community could survive despite environmental or anthropogenic stress.

THE MORPHOMETRIC RESEARCH IN OF THE SPORT
Authors: Karatieieva S. , Slobodian O. , Honchar H. , Penzay S. , Karatieieva A. 
Published: November 2021

The main problem in training athletes is adequate selection and sports affiliation. Solving the problems of selection involves the creation of a model of the athlete of this sport, a certain set of characteristics that determine athletic performance. This requires anthropometric assessment, morphometric and biometric data to track physical and physiological parameters, information to assess performance and recovery in sports, modification of training regimes to prevent injuries, provide guidance on regulating the use of technologies that used in professional sports, as well as to research and make recommendations for the proper collection, storage and exchange of the health information. One of the important problems of modern morphology is the study of the transformations that occur in the body under the influence of various factors. This problem has acquired particular importance in connection with the development of sports. High sports performance associated with significant loads on the athlete's body encourage scientists, doctors, coaches to search for the physiological reserves of the body and search for optimal modes during training. From this point of view, the study of the transformations that take place in individual organs, systems and in the body as a whole, under the influence of physical loads of varying intensity and nature, is relevant and is of great practical importance. Studies have shown changes in the basic physiological and biochemical parameters in athletes, such as adaptation of the muscular, cardiovascular, and respiratory systems, the nature of muscle energy supply, and tissue metabolism processes. There are also scientific studies that reflect structural changes that appear in the body under the influence of physical exertion. The level of results in modern sports is so great that in order to achieve them, athletes need to have appropriate morphological and functional data, as well as excellent physical and mental abilities. Therefore, the main problem of training athletes is adequate selection and sports orientation. Solving the selection problems involves the creation of a model of an athlete of a given specialization, that is, a certain set of features that determine sports performance. The set of features and the order in which they are listed is different for different sports. In the conditions of sports selection, such morphological characteristics as total body dimensions (length), body proportions, body mass composition are taken into account.

O programa Ensino Médio com Mediação Tecnológica (EMMTEC) foi desenvolvido para atender ao alunado residente nas áreas de floresta, agropecuária, ribeirinha, pesqueira, extrativista, quilombola e indígena de todos os municípios rondonienses. O programa teve início em 2016, com o 1º ano do Ensino Médio, prevendo implementação gradual dos demais anos. O EMMTEC possui características similares aos cursos de modalidade da Educação a Distância: as aulas são regidas por professores ministrantes, em Porto Velho, e transmitidas em tempo real para as escolas polo. Nesse contexo, a presente pesquisa – que tem caráter empírico e descritivo, com abordagem qualitativa - foi realizada entre julho de 2017 e março de 2018, objetivando analisar em que medida a formação docente dos professores ministrantes do EMMTEC garante o desenvolvimento dos aspectos metodológicos, tecnológicos e de autonomia. Apresenta-se, aqui, o recorte da pesquisa no que tange aos aspectos metodológicos. Como instrumento de coleta de dados, empregou-se a entrevista semiestruturada. Para a análise dos dados, utilizou-se a técnica categorial temática de análise de conteúdo. Os sujeitos foram escolhidos aleatoriamente, preservando-se a identidade. Os resultados apontam que os professores tiveram uma formação centrada no desempenho em estúdio de gravação, excluindo-se os aspectos metodológicos pertinentes ao ensino com mediação tecnológica, em contraposição ao que é preconizado pelos pesquisadores da área.

Published: November 2021

O artigo analisa o processo de implantação e de consolidação das políticas de accountability na educação pública cearense, refletindo acerca das relações estabelecidas entre governo estadual e municipais neste processo. Apresenta as principais políticas de accountability adotadas no estado. Resulta de revisão bibliográfica acerca da temática proposta e da análise de documentos legais e normativos da política educacional cearense. Numa perspectiva gerencialista da gestão por resultados, o governo do estado do Ceará implantou políticas que articulam medidas de avaliação externa em larga escala, de responsabilização e de prestação de contas que envolvem as redes estadual e municipais de ensino. Tem atuado como regulador e avaliador da educação municipal por meio da implantação de um regime de colaboração “sob condicionalidades” (FREITAS, 2007), orientado para o alcance metas e o pagamento de bonificações.
