Authors: Silva Agnaldo Plácido da , Plácido Eloá Jessica Mendes dos Santos , Moraes Walber Breno de Souza
Published: October 2020

La miiasis se considera una infestación por dermatozoonosis causada por la infestación de larvas dipteranas en tejidos u órganos, que ponen sus óvulos en humanos o animales, que durante un cierto período se alimentan de tejidos vivos o muertos del huésped la aparición de miiasis en la cavidad oral puede considerarse algo raro. Este tipo de enfermedad afecta con mayor frecuencia a personas de bajo nivel socioeconómico, inmunocomprometidos, ancianos postrados en cama y con trastornos psiquiátricos. Debido a su gran potencial destructivo, una prevención y tratamiento oportuno e importante adecuado, también hay poco conocimiento del profesional dental para el diagnóstico y tratamiento de dicha patología, por esta razón, el presente estudio informa de un caso clínico de miiasis oral en una persona de edad avanzada postrada en cama con antecedentes de lesión de neoplasia laríngea/glotal maligna, presentando debilidad física y mental y falta inadecuada de seno de la lengua. El diagnóstico se estableció clínicamente sobre la base de la observación del sangrado de la lengua, el desprendimiento de tejidos y la presencia de larvas que se encontraban entre la segunda y tercera etapas de desarrollo. El tratamiento se inició como hospitalización del paciente para la desbridación de tejidos necróticos y la eliminación de larvas y prescripción de ivermectina. Los pacientes postrados en cama con debilidad física y metálica constituyen un grupo de riesgo para la miiasis oral, y es de gran importancia guiar a los cuidadores y familiares en relación con el cuidado dental con el fin de prevenir esta patología. Sin embargo, la falta de consenso sobre el mejor enfoque terapéutico para los casos de miiasis oral se tomó como conducta terapéutica para la enfermedad la eliminación mecánica de larvas y la institución de uso oral de ivermectina.
THEORETICAL RESEARCH OF THE RECIPE OF SUPPLEMENTARY MATERIAL OF TECHNOLOGICAL PURPOSE FOR ENSURING ECOLOGICAL BEZ-PEPYKHYRA VYROPYRA
Authors: Varlamov Y. , Kotukh V. , Palyeyeva K.
Published: October 2020

In the manufacture (repair) of products of transport pipeline systems, auxiliary materials are widely used, which play the role of lubricants, cooling, cleaning and other substances. Special requirements are imposed on the composition of such substances, which are developed in accordance with the technological instructions, since they are, as a rule, chemically active, surfactants of organic and inorganic origin. Therefore, not only the quality of processing of structural elements of transport pipeline systems, but also the environmental safety of the techno-logical process of their manufacture (repair) depends on the composition and mass fraction of ingredients in these substances. Of particular importance in solving problems on this problem belongs to the theory of predicting the formation of the composition of effective auxiliary materials, assessed by technological, economic, sanitary and hygienic and other indicators that are directly related to the formulation of these materials.
The theoretical foundations and methods for creating auxiliary materials for technological purposes in the practice of specialized enterprises are implemented using the example of a simplified technological scheme. Ac-cording to this scheme, the action of each source of deviations (errors in the composition of the auxiliary material) is evaluated separately, and the other sources are “off,” that is, the principle of superposition is implemented. For a qualitative reflection of the technological uniformity of any two constituent ingredients in terms of their influ-ence coefficients, the concept of "intersection" is used, and all possible intersections between pairs of constituents form a square matrix of intersections of dimensions. The level of effective homogeneity, which predetermines the quality of the auxiliary material for technological purposes, depends on two groups of indicators that equally affect this effective homogeneity. Thus, any variant of the formulation of an auxiliary material consisting of groups of constituents with the maximum level of objective closure always corresponds to a certain variant of an ordered series of ingredients.

Keywords: auxiliary material, transport pipeline systems, error, quality, reliability, environmental safety, manufacturing, repair.

Authors: Talikowska Milena , Ball Stephen , Rose Dan , Bailey Paul , Brink Deon , Stewart Karen , Doyle Matthew , Davids Lauren , Finn Judith
Published: October 2020

Introduction

High quality cardiopulmonary resuscitation (CPR) improves survival from cardiac arrest, yet CPR quality is often suboptimal, even among trained rescuers. St John Western Australia sought to gather anonymous baseline data on CPR performance by paramedics and ambulance officers in a simulation setting.

Methods

In a cross-sectional study, participants performed 2 minutes of CPR on a manikin. CPR quality was recorded and compared to recommended standards. Comparisons were also made between women and men.

Results

The final cohort comprised 1320 participants; 56% paramedics, 20% transport officers and 18% volunteer emergency medical technicians and emergency medical assistants. More than half achieved an overall score of 90% or greater. The median compression score was 96% (IQR 83–99%) while the median ventilation score was 94% (76–99%). Participants achieved the recommended chest compression fraction of ≥60% in 98% of cases. More than half of participants had 99% or more of their compressions reach a depth of ≥50 mm. Two-thirds (68%) recorded a mean compression rate in the range 100–120 compressions per minute. Although there were significant differences in the percentage of compressions deep enough (p<0.01) and the 2-minute mean compression depth (p<0.01) between men and women, the effect size was small. However, men were less likely than women to fully release pressure on the chest after compressions (p<0.01).

Conclusion

This study provides useful baseline data about CPR quality in a manikin model. Participants achieved relatively high scores for most CPR quality metrics and complied with CPR guidelines in the majority of cases.

Authors: Alrawili Khaled Saleh , Osman Kamisah , Almuntasheri Saeed
Published: October 2020

Encouraging students’ higher-order thinking skills (HOTs) has become an ultimate objective for several education programmes. Being a significant domain of scaffolding strategies, HOTs has been considered as a concern that should persistently be at the vanguard of reform agenda of science. The present research aims to examine the effect of scaffolding strategies on HOTs of middle school science students in the context of Saudi Arabia. To carry out the research aim, quasi-experimental design has been applied based on multiple-choice questions comprising 20 questions all distributed on four skills, namely, application, analysis, evaluation and creation. The total population of the research was 84 grade 9 students who all sat for both pre-test and post-test. Convenient sampling was chosen as a sampling method that typically suits both the experimental group (42 students) and the control group (42 students). After collection, data were analysed using both descriptive analysis, mean and standard deviation, and inferential statistics including t-test, one-way analysis of variance (ANOVA) and multivariate ANOVA. The effect of scaffolding strategies on the four skills was found to be significant (p <.01). The present research can contribute to the enhancement of students’ HOTs, provided that scaffolding strategies are applied in science classes and, from a research perspective, will be a reference for researchers who are interested in scaffolding strategies in the context of either Saudi Arabia or other countries. Keywords: higher-order thinking skills, Saudi Arabia, scaffolding strategies, science education
STEM EMBEDDED IN THE DUJIANGYAN IRRIGATION SYSTEM: A DESCRIPTIVE - INTERPRETIVE ANALYSIS TO DESIGN STEM COURSE
Authors: Hong Jon-Chao , Ye Jian-Hong , Ho Ya-Jiuan , Wang Ya-Jun
Published: October 2020

STEM (science, technology, engineering, and mathematics) education is recognized as the world’s top education program. However, few STEM programs have been designed based on cultural-historical events. To explore this issue, the present study drew on the cultural-historical activity theory and the content analysis method by adopting the descriptive-interpretative approach to explore the STEM content of the Dujiangyan Irrigation System (DIS) in present-day Sichuan, China. As early as 2,275 years ago during the Warring States period, Li Bing, the governor of Shu Shire in the Qin state, implicitly implemented the STEM concept when building the irrigation system. The results of this study indicate that the DIS incorporates Science (e.g., the hydraulic principle), Technology (e.g., making a large cobblestone Bamboo-Cage for building Fish Mouth), Engineering (e.g., water-level measurement) and Mathematics (e.g., Calculation of sand discharge). Adopting an educational pedagogy proposed by UNESCO which emphasized learning concepts from daily life, the present study draws on a cultural-historical event to inform STEM learning. The method and results of this study can be applied in the design of STEM programs based on other cultural-historical events from around the world. Keywords: cultural-historical activity theory, Dujiangyan, hydraulic engineering, interdisciplinary knowledge, STEM
ANALYTIC APPROACH OF RESPONSE PATTERN OF DIAGNOSTIC TEST ITEMS IN EVALUATING STUDENTS’ CONCEPTUAL UNDERSTANDING OF CHARACTERISTICS OF PARTICLE OF MATTER
Authors: Laliyo Lukman Abdul Rauf , Tangio Julhim S. , Sumintono Bambang , Jahja Mohamad , Panigooro Citra
Published: October 2020

This research aimed to evaluate the students’ conceptual understanding and to diagnose the students’ preconceptions in elaborating the particle characteristics of matter by development of diagnostic instrument as well as Rasch model response pattern analysis approach. Data were acquired by 25 multiple-choice written test items distributed to 987 students in North Sulawesi, Indonesia. Analysis on diagnostic test items response pattern was conducted in three steps: 1) conversion of raw score to a homogenous interval unit and effectiveness analysis of measurement instruments; 2) measurement of disparity of students’ conceptual understanding; and 3) diagnosis of students’ preconception by estimation of item response pattern. The result generated information on the diagnostic and summative measurement on students’ conceptual understanding in elaborating the topic; information also acts as empirical evidence on the measurement’s reliability and validity. Moreover, the result discovered a significant disparity between students’ conceptual understanding based on their educational level. It was found that the distractor item response pattern tended to be consistent, indicating a certain tendency of resistant preconception pattern. The findings are expected to be a recommendation for future researchers and educational practitioners that integrate diagnostic and summative measurement with Rasch model in evaluating conceptual understanding and diagnosing misconception. Keywords: conceptual understanding, item response, particle of matter, Rasch model

Palkansaajajärjestöjen koulutustoiminnan kehityksen ja lähtökohtien tarkastelua
Authors: Tuomisto Jukka
Published: October 2020

Artikkelissa tarkastellaan palkansaajajärjestöjen (SAK, TVK, STTK ja Akava) koulutustoimintaa ja sen kehitystä. Näiden järjestöjen kasvun myötä ovat myös niiden vaikutusmahdollisuudet yhteiskunnan koko koulutusjärjestelmään lisääntyneet. Samalla niiden oma koulutustoiminta on laajentunut. Erityisesti 1970-luku oli tässä suhteessa voimakasta kasvun kautta. Palkansaajajärjestöjen koulutustoiminta on muodostunut yhä keskeisemmäksi aikuiskasvatuksen osa-alueeksi. Toiminnan lähtökohtia ja kehityspiirteitä ei juurikaan ole tarkasteltu kokonaisvaltaisesti. Artikkeli pyrkii osaltaan poistamaan tätä puutetta.

Published: October 2020

Este artigo mostra o experimento do Ground Penetrating Radar (GPR) aplicado no rio Aturiaí (Augusto Corrêa, Pará, Brasil), que é um dos mais importantes da bacia hidrográfica do município de Augusto Corrêa. Este rio tem um comprimento de 15 km e uma largura que varia entre 8 m e mais de 200 m na foz, com profundidade entre 0,8-1 m na cabeceira, 1,2-1,5 m na parte média e 1,6-2 m na foz. Durante o período seco, a salinidade é mais alta e com valores entre 0,05 (parte interna) e 30,9 (foz), bem próximos da salinidade oceânica. O rio atravessa o manguezal na planície costeira Bragantina e deságua no estuário do rio Caeté. Os resultados mostram que com a antena de frequência de 200 MHz, o GPR consegue obter registros (radargramas) da subsuperfície do rio, com mais de 3 m de profundidade, atingindo a sequência transgressiva basal (S1), sendo constituída por areias e lamas de origem marinha/estuarina na base (3-6 m). A granulometria dos sedimentos revela que a areia é a principal classe dominante (58%) nos fundos do rio, e o tamanho das partículas diminui da montante à foz. Avaliou-se a performance do GPR na detecção dos estratos do subfundo do rio Aturiaí, durante um ciclo sazonal, com salinidade alta e baixa.

Published: October 2020

The PSE (Pale, Soft and Exudative) swine meat is an anomaly that produces great economic losses in the swine industry and products because proteins lose their functionality, affecting the ability of water retention, binding, and emulsification of meat. Due to the importance of quality control of carcasses, the determination of the pH parameter is necessary to perform the classification of the product in: normal; PSE; and DFD (Dark, Firm, and Dry). In this sense, the purpose of the work was to perform the evaluation of pH values after 45 minutes of bleeding (pH45) and function of the distance from farms to a slaughterhouse and calculate the indicator of Meat PSE in swine carcasses. The experiment was carried out in a large plant, under the supervision of the Federal Inspection Service (SIF). A total of 725 carcasses were used, separated into lots and the transport distance from the farms to the slaughterhouse ranged from 25 to 427 km. For the evaluation of the incidence of PSE, pH45 was measured by a direct method, and the management of pre-slaughter animals was standardized for all lots, except for rest time. The animals transported for shorter distances (25 and 65 km) presented 11% indicative of PSE meat, a fact that shows that the stress response is higher when the animals are subjected to short transport distances compared to longer distances (320, 340, and 427 km).

Published: October 2020

Leptospirosis is one of the most widespread zoonosis in the world. In humans, the disease is responsible for more than a million cases annually. The purpose of this study was to assess human seroprevalence to leptospirosis in a rural community of southernmost Brazil. Furthermore, we assess possible epidemiological cues associated with seroprevalence. A total of 216 individuals were enrolled in the study. With an overall seroprevalence of 21.3% (n=46), to at least one of the 12 antigens tested. Seroreactivity was associated with 13 of the investigated cues, including those associated with the individuals, their behavior, environment, domestic animals, and synanthropic rodents. While seroprevalence was not particularly high when compared to other studies in similar populations, some of the risk factors associated with the disease are easy to circumvent, and indications for policymakers and future studies are made within.

Published: October 2020

Este artigo resulta de uma pesquisa de mestrado que analisou o movimento formativo de professores dos anos iniciais, sobre diferentes significados de frações e suas relações com o ensino em formação docente. Promoveu-se um espaço de formação de professores dos anos iniciais do Ensino Fundamental de escolas públicas a partir de um curso de extensão, para investigar, discutir e explorar conhecimentos sobre o conceito de frações e seus diferentes significados e práticas pedagógicas e, onde foram produzidos os dados,  por meio de filmagens, imagens, gravações audiovisuais, relatos escritos e gravados, fórum de discussões, narrativas e questionários inicial e final dando a esta pesquisa uma característica qualitativa. O objetivo deste artigo é investigar o processo formativo ao tratarem no coletivo a ideia de fração como parte-todo a partir da parte e, identificar cenas que indicaram apropriações desse conceito desses professores cursistas. O estudo está embasado nos pressupostos da Teoria Histórico-Cultural e se aproxima do Materialismo Histórico Dialético como método de pesquisa e do movimento logico histórico do conceito como base de aprendizagem e do trabalho de ensinar do professor. Investigamos o movimento formativo daquele coletivo sobre a composição do inteiro a partir da parte identificamos cenas que comprovaram que houve apropriação ou ampliação de conhecimento sobre as diferentes possibilidades de composição desse inteiro conhecida a parte. Concluímos que a fração parte-todo, mesmo sendo uma das ideias citadas em estudos como a mais praticada e conhecida por professores, precisa ser abordada de distintas maneiras e necessita ser discutida em formação continuada.
Analyze the Attentive & Bypass Bias: Mock Vignette Checks in Survey Experiments
Authors: Kane John V. , Velez Yamil R. , Barabas Jason
Published: October 2020

Respondent inattentiveness threatens to undermine experimental studies. In response, researchers incorporate measures of attentiveness into their analyses, yet often in a way that risks introducing post-treatment bias. We propose a design-based technique—mock vignettes (MVs)—to overcome these interrelated challenges. MVs feature content substantively similar to that of experimental vignettes in political science, and are followed by factual questions (mock vignette checks [MVCs]) that gauge respondents’ attentiveness to the MV. Crucially, the same MV is viewed by all respondents prior to the experiment. Across five separate studies, we find that MVC performance is significantly associated with (1) stronger treatment effects, and 2) other common measures of attentiveness. Researchers can therefore use MVC performance to re-estimate treatment effects, allowing for hypothesis tests that are more robust to respondent inattentiveness and yet also safeguarded against post-treatment bias. Lastly, our study offers researchers a set of empirically-validated MVs for their own experiments.

Published: October 2020

This paper presents a hypothesis that can explain why similar essential amino acids requirements have been conserved among all heterotrophic eukaryotes. In an analysis of a food composition table, the first principal component of the amino acid compositions of daily foods was found to separate essential and non-essential amino acids. Regarding all foods from eukaryotes, this finding indicate that all eukaryotes have common components rich in essential amino acids. Previous studies have indicated that yeast, a eukaryote, can use its cytoplasmic components as a primary source of amino acids by autophagy, and all terrestrial organism cells showed similar amino acid compositions. If all eukaryotic cells depend on their cytoplasmic components as primary amino acid sources and if all eukaryotes maintain them rich in essential amino acids, it would be reasonable for heterotrophic eukaryotes to have lost the need to synthesize amino acids that are already stored inside their cells.

In the application of the brain-computer interface, feature extraction is an important part of Electroencephalography (EEG) signal classification. Using sparse modeling to extract EEG signal features is a common approach. However, the features extracted by common sparse decomposition methods are only of analytical meaning, and cannot relate to actual EEG waveforms, especially event-related potential waveforms. In this article, we propose a feature extraction method based on a self-organizing map of sparse dictionary atoms, which can aggregate event-related potential waveforms scattered inside an over-complete sparse dictionary into the code book of neurons in the self-organizing map network. Then, the cosine similarity between the EEG signal sample and the code vector is used as the classification feature. Compared with traditional feature extraction methods based on sparse decomposition, the classification features obtained by this method have more intuitive electrophysiological meaning. The experiment conducted on a public auditory event-related potential (ERP) brain-computer interface dataset showed that, after the self-organized mapping of dictionary atoms, the neurons’ code vectors in the self-organized mapping network were remarkably similar to the ERP waveform obtained after superposition and averaging. The feature extracted by the proposed method used a smaller amount of data to obtain classification accuracy comparable to the traditional method.

Aircraft and engine technology have continuously evolved since their introduction and significant improvement has been made in fuel efficiency, emissions, and noise reduction. One of the major issues that the aviation industry is facing today is pollution around the airports, which has an effect both on human health and on the climate. Although noise emissions do not have a direct impact on climate, variations in departure and arrival procedures influence both CO2 and non-CO2 emissions. In addition, design choices made to curb noise might increase CO2 and vice versa. Thus, multidisciplinary modeling is required for the assessment of these interdependencies for new aircraft and flight procedures. A particular aspect that has received little attention is the quantification of the extent to which early design choices influence the trades of CO2, NOx, and noise. In this study, a single aisle thrust class turbofan engine is optimized for minimum installed SFC (Specific Fuel Consumption). The installed SFC metric includes the effect of engine nacelle drag and engine weight. Close to optimal cycles are then studied to establish how variation in engine cycle parameters trade with noise certification and LTO (Landing and Take-Off) emissions. It is demonstrated that around the optimum a relatively large variation in cycle parameters is allowed with only a modest effect on the installed SFC metric. This freedom in choosing cycle parameters allows the designer to trade noise and emissions. Around the optimal point of a state-of-the-art single aisle thrust class propulsion system, a 1.7 dB reduction in cumulative noise and a 12% reduction in EINOx could be accomplished with a 0.5% penalty in installed SFC.
Opioid-Induced Immunomodulation: Consequences for the Experimental Coxsackievirus B3-Induced Myocarditis Model
Authors: Pappritz Kathleen , Van Linthout Sophie
Published: October 2020

Myocarditis is an inflammatory disorder of the heart predominantly caused by infectious agents. Since more than sixty years, the Coxsackievirus B3 (CVB3)-induced myocarditis mouse model is the experimental model used to investigate viral myocarditis. The pathogenesis of viral myocarditis is conceptually a multiphase process, initiated by the infection of cardiomyocytes, followed by activation of the immune system, and resulting in myocardial fibrosis and left ventricular dysfunction. In parallel to the direct infection of the heart, CVB3 replicates in lymphatic organs such as the pancreas. Due to infection of the pancreas, the model of experimental CVB3-induced myocarditis is estimated as a severe burden for the challenged animals. Application of analgesics in frame of the animal welfare act (European directive 2010/63/EU) is more and more becoming a matter of debate. For this purpose, we summarized published studies for 13 different opioids and discussed their potential impact on CVB3-induced myocarditis. In addition, with this summary we also want to provide guidance for researchers beyond the myocarditis field to estimate the impact of opioids on the immune system for their specific model. In the literature, both immunosuppressive as well as immune-activating effects of opioids have been described, but examinations in experimental CVB3-induced myocarditis have still not been reported so far. Based on the existing publications, administration of opioids in experimental CVB3-induced myocarditis might result in more severe disease progression, including higher mortality, or a less pronounced myocarditis model, failing to be used for the establishment of new treatment options. Taken together, the applicability of opioids in experimental CVB3-induced myocarditis and in inflammatory models in general needs to be carefully evaluated and further investigated.

The stop signal task has been used to quantify the human inhibitory control. The inter-subject and intra-subject variability was investigated under the inhibition of human response with a realistic environmental scenario. In present study, we used a battleground scenario where a sniper-scope picture was the background, a target picture was a go signal, and a nontarget picture was a stop signal. The task instructions were to respond on the target image and inhibit the response if a nontarget image appeared. This scenario produced a threatening situation and endorsed the evaluation of how subject’s response inhibition manifests in a real situation. In this study, 32 channels of electroencephalography (EEG) signals were collected from 20 participants during successful stop (response inhibition) and failed stop (response) trials. These EEG signals were used to predict two possible outcomes: successful stop or failed stop. The inter-subject variability (between-subjects) and intra-subject variability (within-subjects) affect the performance of participants in the classification system. The EEG signals of successful stop versus failed stop trials were classified using quadratic discriminant analysis (QDA) and linear discriminant analysis (LDA) (i.e., parametric) and K-nearest neighbor classifier (KNNC) and Parzen density-based (PARZEN) (i.e., nonparametric) under inter- and intra-subject variability. The EEG activities were found to increase during response inhibition in the frontal cortex (F3 and F4), presupplementary motor area (C3 and C4), parietal lobe (P3 and P4), and occipital (O1 and O2) lobe. Therefore, power spectral density (PSD) of EEG signals (1-50Hz) in F3, F4, C3, C4, P3, P4, O1, and O2 electrodes were measured in successful stop and failed stop trials. The PSD of the EEG signals was used as the feature input for the classifiers. Our proposed method shows an intra-subject classification accuracy of 97.61% for subject 15 with QDA classifier in C3 (left motor cortex) and an overall inter-subject classification accuracy of 71.66% ± 9.81% with the KNNC classifier in F3 (left frontal lobe). These results display how inter-subject and intra-subject variability affects the performance of the classification system. These findings can be used effectively to improve the psychopathology of attention deficit hyperactivity disorder (ADHD), obsessive-compulsive disorder (OCD), schizophrenia, and suicidality.

Dystonia is a heterogeneous group of hyperkinetic movement disorders. The unifying descriptor of dystonia is the motor manifestation, characterized by continuous or intermittent contractions of muscles that cause abnormal movements and postures. Additionally, there are psychiatric, cognitive, and sensory alterations that are possible or putative non-motor manifestations of dystonia. The pathophysiology of dystonia is incompletely understood. A better understanding of dystonia pathophysiology is highly relevant in the amelioration of significant disability associated with motor and non-motor manifestations of dystonia. Recently, diminished olfaction was found to be a potential non-motor manifestation that may worsen the situation of subjects with dystonia. Yet, this finding may also shed light into dystonia pathophysiology and yield novel treatment options. This article aims to provide background information on dystonia and the current understanding of its pathophysiology, including the key structures involved, namely, the basal ganglia, cerebellum, and sensorimotor cortex. Additionally, involvement of these structures in the chemical senses are reviewed to provide an overview on how olfactory (and gustatory) deficits may occur in dystonia. Finally, we describe the present findings on altered chemical senses in dystonia and discuss directions of research on olfactory dysfunction as a marker in dystonia.

Pediatric surveillance through screening procedures is needed to detect warning signs of risk for Autism Spectrum Disorder under 24 months of age and to promote early diagnosis and treatment. The main purpose of this study is to extend the literature regarding the psychometric properties of two screening tools, the First Year Inventory (FYI) and the Quantitative-CHecklist for Autism in Toddler (Q-CHAT), testing their criterion validity. They were administered during a three-wave approach involving the general population. At T1, 657 children were tested with the FYI and 36 of them were found to be at risk. At T2, 545 were tested with the Q-CHAT and 29 of them were found to be at risk. At T3, 12 out of the 36 children with a high score on the FYI and 11 out of the 29 children with a high score on the Q-CHAT were compared to 15 typically developing children. The criterion validity was tested considering the severity of the autistic symptoms, emotional/behavioral problems, and limited global functioning as criteria. Accuracy parameters were also calculated. Furthermore, we investigated which dimension of each questionnaire better predicted the aforementioned criterion. The results corroborated the hypotheses and confirmed the criterion validity of FYI and Q-CHAT.
Privacy-Preserving and Efficient Public Key Encryption with Keyword Search Based on CP-ABE in Cloud

Published: October 2020

In the area of searchable encryption, public key encryption with keyword search (PEKS) has been a critically important and promising technique which provides secure search over encrypted data in cloud computing. PEKS can protect user data privacy without affecting the usage of the data stored in the untrusted cloud server environment. However, most of the existing PEKS schemes concentrate on data users’ rich search functionalities, regardless of their search permission. Attribute-based encryption technology is a good method to solve the security issues, which provides fine-grained access control to the encrypted data. In this paper, we propose a privacy-preserving and efficient public key encryption with keyword search scheme by using the ciphertext-policy attribute-based encryption (CP-ABE) technique to support both fine-grained access control and keyword search over encrypted data simultaneously. We formalize the security definition, and prove that our scheme achieves selective indistinguishability security against an adaptive chosen keyword attack. Finally, we present the performance analysis in terms of theoretical analysis and experimental analysis, and demonstrate the efficiency of our scheme.
