ABSTRACT

BACKGROUND: Different modalities of quarantines were one of the main measures implemented worldwide to avoid the spread of SARS-CoV2 virus. AIM: To analyze and compare retrospectively the implementation of the Step- to-Step plan devised by the Chilean Ministry of Health during the pandemic. To propose a decision-making path based on an artificial intelligence fuzzy system to determine confinements in specific territories. MATERIAL AND METHODS: The Step-to-Step Plan threshold values such hospital network capacity, epidemic spreading, testing and contact tracing capability were modeled using fuzzy numbers and fuzzy rule-based systems. RESULTS: Ministry of Health's decision-making opportuneness were unrelated with the Step-to-Step Plan indicators for deconfinement. Such disagreements undermined epidemiological indicators. CONCLUSIONS: Using an artificial intelligence system could improve decision-making transparency, emergency governance, and risk communication to the population.

ABSTRACT

Recording of peripheral pulse serves as a very important and essential non-invasive tool used widely by doctors for the diagnosis of various diseases. The morphology of pulse is seen to vary as a function of time in a given individual and also from individual to individual. There are many variations in morphological patterns of peripheral pulse in different disease conditions, which lead to difficulty in accurate diagnosis. The peripheral pulse waveforms are extracted from radial arteries as time series data using a peripheral pulse analyzer which is designed on the principle of impedance plethysmography. It was first introduced by Nyober in the mid-nineteen hundreds and ameliorated further by Kubicek. It involves the recording of the instantaneous blood volume by the measurement of electrical impedance as a function of time. Therefore, the study of peripheral pulse morphology has gained much attention in the past few years among researchers. Physiological variability is one of the recent investigations added during the last two decades for the objective assessment of autonomic function and the assessment of prognosis in severe sicknesses namely myocardial infarction, diabetic neuropathy, etc. In addition to heart rate variability studied worldwide, few researchers have studied blood pressure variability and peripheral blood flow variability. In this computer era, artificial intelligence and machine learning techniques have become more important day-by- day, and different types of algorithms were used for the identification of hidden patterns from plethysmographic observations on the radial pulse such as support vector machine as well as crisp and fuzzy clustering. Eight patterns were classified with a yield of 80%–90% and helped with the diagnosis of disorders such as myocardial infarction, pulmonary tuberculosis, coronary artery disorders, cirrhosis of the liver, and bronchial asthma. This paper briefly describes the use of machine learning techniques for the classification of peripheral pulse morphologies.

ABSTRACT

Feature extraction methods and classifier selection are two critical steps in heart sound classification. To capture the pathological features of heart sound signals, this paper introduces a feature extraction method that combines mel-frequency cepstral coefficients (MFCC) and power spectral density (PSD). Unlike conventional classifiers, the adaptive neuro-fuzzy inference system (ANFIS) was chosen as the classifier for this study. In terms of experimental design, we compared different PSDs across various time intervals and frequency ranges, selecting the characteristics with the most effective classification outcomes. We compared four statistical properties, including mean PSD, standard deviation PSD, variance PSD, and median PSD. Through experimental comparisons, we found that combining the features of median PSD and MFCC with heart sound systolic period of 100-300 Hz yielded the best results. The accuracy, precision, sensitivity, specificity, and F1 score were determined to be 96.50%, 99.27%, 93.35%, 99.60%, and 96.35%, respectively. These results demonstrate the algorithm's significant potential for aiding in the diagnosis of congenital heart disease.

ABSTRACT

Background Grassroots center for disease control and prevention (CDC) staff undertake intensive work of disease prevention and control, and may be susceptible to occupational stress, anxiety, depression, and other health problems. Objective To understand the current situation of occupational stress, anxiety, and depression among grassroots CDC staff, and to identify potential risk factor configurations for occupational stress, anxiety, and depression using fuzzy set qualitative comparative analysis (fsQCA), so as to provide a basis for effective intervention. Methods The staff working in county/district-level CDCs in Hebei Province were the target population of the current study. Stratified random cluster sampling method was used to select 1860 staff members of the target population. A questionnaire of general situation, Job Content Scale, 7-item Generalized Anxiety Disorder Scale, and Patient Health Questionnaire-9 were used. Risk factor configurations associated with health outcomes of interest were identified by fsQCA3.0 software. Results The positive rates of occupational stress, anxiety, and depression were 42.69%, 44.25%, and 47.96%, respectively. Marital status was a necessary condition for occupational stress, anxiety, and depression in the grassroots CDC staff (the necessity values were 0.911, 0.939, and 0.933, respectively). There were two types of risk factor configurations for occupational stress: "self-improvement" and "disease burden"; the risk factor configurations for anxiety were "disease burden" and "economic-disease burden"; while the risk factor configurations for depression were "disease burden", "economic-disease burden", and "self-improvement". The overall consistency scores of occupational stress, anxiety, and depression were 0.941, 0.820, and 0.774, respectively. Regarding outstanding components, "self-improvement" included pressure of job requirements and promotion, "disease burden" included impact of chronic illness on psychological state, and "economic-disease burden" included not only impact of chronic illness but also financial support for CDC staff. Conclusion All positive rates of occupational stress, anxiety, and depression are high among grassroots CDC staff in Hebei Province. Occupational stress, anxiety, and depression of grassroots CDC staff are the results of multiple influencing factors, so targeted intervention measures should be formulated.

ABSTRACT

Abstract: Microgrids (MD) is a new technology to improve efficiency, resilience, and reliability in the electricity sector. MD are most likely to have a clean energy generation, but the increase of microgrids with this kind of generation brings new challenges for energy management (EMS), especially concerning load uncertainties and variation of energy generation. In this context, this study has the main objective to propose a method of how to attend this matter, verifying the difference between the day before and real-time. The EMS proposed analyses the MD in real-time, calculating the deviation between dispatched and what was predicted to happen in the operation point in a three-dimensional analysis approach, considering renewable energy generation, battery State of Charge (SOC) and load curve. The system categorized the deviation in three possible quantities (small, medium, or high) and it acts accordingly. For the Next Operation Point predictor are used an artificial neural network (ANN) methodology. For the Decision Support System, it's used a fuzzy logic system to adjust the next operation point, and it uses a mixed-integer linear programming (MILP) approach when the deviation is too high, and the dispatched operation is unfeasible. Simulations with real data and information of a pilot project of MD are carried out to test and validate the proposed method. Results show that the methodology used to attend the matters of uncertainties and variation of energy generation. A reduction of operational cost is observed in the simulations.

ABSTRACT

It was pointed out in Opinions on Promoting the Inheritance, Innovation and Development of Traditional Chinese Medicine issued by the State Council in 2019 that 100 varieties of traditional Chinese medicine(TCM) with unique curative effects should be screened out within about three years. Due to the multi-component and multi-target mechanisms of TCM varieties, it is difficult to directly and simply evaluate their multi-dimensional clinical value using methods applicable to chemical or biological agents. The heterogeneity of outcomes for similar TCM makes it difficult to determine the advantages of similar products. The fuzzy comprehensive evaluation method that is developed on the basis of core outcome set and fuzzy mathematics for clinical efficacy evaluation of TCM may solve these problems. This study developed a fuzzy comprehensive evaluation model for the clinical efficacy evaluation of Chinese patent me-dicines for coronary heart disease and angina pectoris, and selected the previous normative studies with complete or incomplete data for verifying the model application. The results showed that original studies with complete data failed to evaluate and compare the comprehensive efficacy of different interventions. The original research only mentioned the advantages and disadvantages of different interventions in different aspects. The comprehensive clinical efficacy of three different interventions obtained through fuzzy comprehensive evaluation was all graded as level Ⅱ. The original research with incomplete data drew the same conclusions as the fuzzy comprehensive evaluation, and the results of fuzzy comprehensive evaluation can provide more comprehensive information. Therefore, the fuzzy comprehensive evaluation shows the products with overall advantages of clinical efficacy, which may become a feasible method for the screening of TCM.

ABSTRACT

RESUMEN La lógica difusa trata de copiar la forma en que los humanos toman decisiones. Específicamente en el área médica, se utiliza desde hace varios años en estudios aplicados a áreas como: ingeniería biomédica, sistemas expertos, modelos epidemiológicos y sistemas diagnósticos. Se confeccionó un cuestionario para medir la calidad de vida relacionada con la salud oral en adolescentes cubanos; se utilizó la lógica difusa en el proceso de validación por expertos, mediante el software PROCESA_CE (2013). En el nivel de concordancia de los expertos se rechazó la hipótesis nula de que no existe comunidad de preferencia entre ellos, para un nivel de significación de 0,01; esto garantizó, con un 99% de confiabilidad, que es posible hacer valoraciones a partir del consenso de estos expertos. Además, se corroboró la existencia de un consenso de 5 en todos los ítems.


ABSTRACT Fuzzy logic tries to copy the way humans make decisions. It has been used for several years, specifically in the medical field, in studies applied to areas such as biomedical engineering, expert systems, epidemiological models and diagnostic systems. A questionnaire was prepared to measure the quality of life related to oral health in Cuban adolescents; Fuzzy logic was used in the validation process based on expert criteria, using the PROCESA_CE (2013) software. According to expert agreements, the null hypothesis that there is no community of preference among them was rejected, for a significance level of 0.01; this guaranteed, with 99% reliability, that it is possible to make assessments based on their consensuses. In addition, the existence of a consensus of five in all items was corroborated.

ABSTRACT

ABSTRACT With the continuous improvement of people's material living standards, public health and national fitness has become a social topic, and has been widely concerned by the public, in terms of the traditional physical education and impact of the concept of health. This not only needs the school to carry on the multi-directional adjustment to the physical education teaching, but also needs the physical education teacher to respond positively to this in order to adapt to the development needs of the times and society. This study uses the analytic hierarchy process (AHP) to construct the professionalization model of physical education teachers in Colleges and Universities, and makes decision on the index weight of the model through fuzzy comprehensive evaluation. The results show that the weight of the first-class indicators of P.E. Teachers' professionalization model from large to small is ability > quality > knowledge, and the consistency ratio (CR) of the model indicators is less than 0.1, and the fuzzy score of the model is 85 points. Therefore, the model of P.E. Teachers' professionalization constructed in this study has consistent indicators and shows good applicability. This does not only provide the basis for the professional development evaluation of College PE teachers, but also provides research ideas for the development of the sports industry from the perspective of public health.


RESUMO Com a melhoria contínua dos padrões de vida materiais das pessoas, a saúde pública e a saúde nacional tornaram-se um tema social, e tem sido amplamente discutido pelo público, em termos de educação física tradicional e impacto do conceito de saúde, que depende não só da escola para continuar o ajuste multidirecional para o ensino de educação física, mas também precisa do professor de educação física para dar uma resposta positiva a isso, a fim de se adaptar às necessidades de desenvolvimento dos tempos e da sociedade. Este estudo utiliza o processo hierárquico analítico (AHP) para construir o modelo de profissionalização dos professores de educação física em faculdades e universidades, e toma uma decisão sobre o peso do índice do modelo através de uma avaliação abrangente. Os resultados mostram que o peso dos indicadores de primeira classe do modelo de profissionalização dos professores de grande para pequeno é a capacidade > qualidade > conhecimento, e a razão de consistência dos indicadores do modelo é menor que 0.1, e a pontuação difusa do modelo é 85 pontos. Assim, o modelo de profissionalização dos professores de educação física, construído neste estudo, tem boa consistência de indicadores e mostra boa aplicabilidade. Isto não só proporciona a base para a avaliação do desenvolvimento profissional dos professores universitários de educação física, mas também fornece ideias de investigação para o desenvolvimento da indústria desportiva sob a perspectiva da saúde pública.


RESUMEN Con la mejora continua del nivel de vida material de las personas, la salud pública y la buena condición física nacional se han convertido en un tema social, y han sido motivo de una amplia preocupación en la población, con respecto a la educación física tradicional y su impacto en el concepto de salud. Esto no solo necesita que la escuela lleve a cabo el ajuste multidireccional de la enseñanza de educación física, sino también que el docente de educación física responda positivamente para adaptarse a las necesidades de desarrollo de los tiempos y la sociedad. Este estudio utiliza el proceso de jerarquía analítica (PJA) para construir el modelo de profesionalización de los docentes de educación física en los colegios y universidades, y analiza el peso del índice del modelo a través de una evaluación integral difusa. Los resultados muestran el peso de los indicadores de primera clase del modelo de profesionalización de los docentes, de mayor a menor, es capacidad> calidad> conocimiento, y el índice de consistencia (IC) de los indicadores del modelo es menor a 0.1, y la puntuación difusa del modelo es de 85 puntos. Por tanto, el modelo de profesionalización docente construido en este estudio tiene indicadores consistentes y muestra buena aplicabilidad. Esto no solo proporciona la base para la evaluación del desarrollo profesional de los profesores de educación física universitaria, sino que también ofrece ideas de investigación para el desarrollo de la industria del deporte desde la perspectiva de la salud pública.

ABSTRACT

Abstract This paper aims to evaluate the perception of residents of a rural quilombola community, about the impacts of distributed energy generation (DG) on the social, economic and environmental dimensions. The main challenge of the proposed model was to quantify the main perceptions of the target population of the research, as well as maintain the coherence of the specifications of the sustainability parameters. Diffuse modeling allows the transformation of linguistic variables into numerical values, the disadvantage is the dependence of the specialist to construct the rules. The methodology used was the application of a semi-structured questionnaire, and the results were used as a reference to build the discourse domain of the input variables of the Fuzzy inference system, which generated an index of 54.1% classified in the category partially sustainable. Specifically, the economic and social dimensions obtained an index of 46.7% and the environmental dimension of 69%. From the perspective of the perception of the respondents, the variables with the greatest impact were: landscape change (LCH) 92%, environmental awareness (EA) and reduction of global warming (GW) with values of both 69%. The variable of the most prominent economic dimension was: cost of the system with a value of 69%. In the social dimension, the variables with the greatest impact were: Community Acceptability (AC), Expansion of the support network (ESN) with values of 69%. The proposed model allowed us to interpret the respondents' perception, and can be used to generate effective actions that solve the identified demands.

ABSTRACT

Abstract The proficiency of image processing is of extreme importance in perceiving and collecting information from the images, which includes the process of changing or interpreting existing images. In medical image processing, imaging with more accuracy plays a crucial role in better diagnosis or for the posterior analysis of treatment. Magnetic Resonance Imaging (MRI) is a medicinal creative tool for studying the internal structures and functionalities of human brain, knee, heart, liver, etc. Typical MR scans are essential now for better diagnosis but, limited resolution that is often inadequate for extracting detailed and reliable information. So, for the super resolution (SR) of MR brain images concepts of compressive sensing (CS) & fuzzy logical rules to improve data quality are proposed in this paper. Usually, reconstruction of an SR image is the formation of high resolution (HR) image which is obtained from one or few low resolution (LR) images. In the proposed method, with the help of compressive sensing a very limited number of images are considered even though it's a challenging task and fuzzy logical rules for a specific membership function are applied to improve the resolution of the image. To assess the performance of the proposal, different metrics are evaluated and achieved better results.

ABSTRACT

OBJECTIVE@#By optimizing the extreme learning machine network with particle swarm optimization, we established a syndrome classification and prediction model for primary liver cancer (PLC), classified and predicted the syndrome diagnosis of medical record data for PLC and compared and analyzed the prediction results with different algorithms and the clinical diagnosis results. This paper provides modern technical support for clinical diagnosis and treatment, and improves the objectivity, accuracy and rigor of the classification of traditional Chinese medicine (TCM) syndromes.@*METHODS@#From three top-level TCM hospitals in Nanchang, 10,602 electronic medical records from patients with PLC were collected, dating from January 2009 to May 2020. We removed the electronic medical records of 542 cases of syndromes and adopted the cross-validation method in the remaining 10,060 electronic medical records, which were randomly divided into a training set and a test set. Based on fuzzy mathematics theory, we quantified the syndrome-related factors of TCM symptoms and signs, and information from the TCM four diagnostic methods. Next, using an extreme learning machine network with particle swarm optimization, we constructed a neural network syndrome classification and prediction model that used "TCM symptoms + signs + tongue diagnosis information + pulse diagnosis information" as input, and PLC syndrome as output. This approach was used to mine the nonlinear relationship between clinical data in electronic medical records and different syndrome types. The accuracy rate of classification was used to compare this model to other machine learning classification models.@*RESULTS@#The classification accuracy rate of the model developed here was 86.26%. The classification accuracy rates of models using support vector machine and Bayesian networks were 82.79% and 85.84%, respectively. The classification accuracy rates of the models for all syndromes in this paper were between 82.15% and 93.82%.@*CONCLUSION@#Compared with the case of data processed using traditional binary inputs, the experiment shows that the medical record data processed by fuzzy mathematics was more accurate, and closer to clinical findings. In addition, the model developed here was more refined, more accurate, and quicker than other classification models. This model provides reliable diagnosis for clinical treatment of PLC and a method to study of the rules of syndrome differentiation and treatment in TCM.

ABSTRACT

Objective:To propose a method of image similarity measurement based on structure information and intuitionistic fuzzy set and measure the similarity between CT image and CBCT image of radiotherapy plan positioning, aiming to objectively measure the setup errors.Methods:A total of four pre-registration images of a nasopharyngeal carcinoma patient on the cross-sectional and sagittal planes and a pelvic tumor patient on the cross-sectional and coronal planes were randomly selected. Five methods were used to quantify the setup errors, including correlation coefficient, mean square error, image joint entropy, mutual information and similarity measure method.Results:All five methods could describe the deviation to a certain extent. Compared with other methods, the similarity measure method showed a stronger upward trend with the increase of errors. After normalization, the results of five types of error increase on the cross-sectional plane of the nasopharyngeal carcinoma patient were 0.553, 0.683, 1.055, 1.995, 5.151, and 1.171, 1.618, 1.962, 1.790, 3.572 on the sagittal plane, respectively. The results of other methods were between 0 and 2 after normalization, and the results of different errors of the same method slightly changed. In addition, the method was more sensitive to the soft tissue errors.Conclusions:The image similarity measurement method based on structure information and intuitionistic fuzzy set is more consistent with human eye perception than the existing evaluation methods. The errors between bone markers and soft tissues can be objectively quantified to certain extent. The soft tissue deviation reflected by the setup errors is of significance for individualized precision radiotherapy.
