The purpose of this study was to investigate the mediating role of dimensions of spiritual intelligence in the relationship between mindfulness and expressed emotion in the caregivers of epileptic patients. Materials and Methods: This was a descriptive cross-sectional study. The study sample consisted of 90 epileptic patients and their caregivers that were selected by convenience sampling method and responded to the expressed emotion, Kentucky Mindfulness Skills, and Spiritual Intelligence questionnaires. The hypothesis of the research was investigated by hierarchical regression analysis using the proposed steps of Baron and Kenny. Results: The hierarchical multiple regression analysis showed that in the first step, mindfulness (beta=-0.39) can predict expressed emotion. In the second step, mindfulness (beta=-0.28) and only the ability to deal with problems dimension of spiritual intelligence (beta=-0.27) predict expressed emotion. Due to the decrease of the beta value of mindfulness in the second stage compared to the first stage, the partial mediating role of the ability to deal with problems in the relationship between mindfulness and the expressed emotion is confirmed. Conclusion: Mindfulness is associated with the expressed emotion of caregivers of patients with epilepsy, and the ability to deal with problems as one of the dimensions of spiritual intelligence plays a mediating role. Therefore, it is suggested to pay more attention to psychological training in promoting the mindfulness and spiritual intelligence of caregivers of epileptic patients.s
摘要本研究旨在探讨精神智力各维度在癫痫患者照护者正念与情绪表达关系中的中介作用。材料和方法:这是一项描述性横断面研究。本研究以90名癫痫患者及其护理人员为研究对象,采用方便抽样法进行情绪表达、肯塔基正念技能和精神智力问卷调查。采用Baron和Kenny提出的步骤,对研究假设进行了层次回归分析。结果:层次多元回归分析显示,在第一步,正念(beta=-0.39)可以预测情绪表达。在第二步中,正念(beta=-0.28)和只有处理问题的能力的精神智力维度(beta=-0.27)预测表达的情绪。由于第二阶段正念的beta值较第一阶段有所下降,因此,在正念与情绪表达的关系中,处理问题能力的部分中介作用得到了证实。结论:正念与癫痫患者照顾者的情绪表达相关,处理问题的能力作为精神智力的一个维度起中介作用。因此,建议加强心理训练,提高癫痫患者照顾者的正念和精神智力

1. COVID-19 2. Physical Dis tancing 3. Quarantine Introduction: Covid-19 pandemic has created a worldwide emergency that poses a devas tating threat to mental health, economic, and social indicators. Social dis tancing and quarantine have seriously damaged social relations. The quarantine can lead to socio-economic problems, such as long-term unemployment, job losses, and declining family incomes in many countries. Declining social relations and changing economic conditions can lead to serious crises, particularly psychological issues, in metropolitan areas. Hence, it is necessary to look at these aspects that have received less attention. Materials and Methods: In this s tudy, the socio-economic aspects of COVID-19 disease in Tehran collected from 200,000 citizens based on qualitative indicators in the form of a ques tionnaire, and then the data were analyzed. Results: The results of this project showed that people’s responses are very different depending on the type of job (private, government, informal, and self-employment). The type of employment relationship is decisive in answering ques tions, such as job loss during and after the corona pandemics, living standards, and reduced cos ts of luxury goods. Conclusion: In order to reduce the social risks, non-governmental organizations and the government should prepare and implement programs to ensure job security, create a desire to save, produce s tructured job opportunities, and develop skills.s ABSTRACT Article Info:

1. Seizures 2. Electroencephalography 3. Passive Cutaneous Anaphylaxis Introduction: Electroencephalography (EEG) is the mos t commonly used method to s tudy the function of the brain. This s tudy represents a computerized model for dis tinguishing between epileptic and healthy subjects using EEG signals with relatively high accuracy. Materials and Methods: The EEG database used in this s tudy was obtained from the data available in Andrzejak. This dataset consis ts of 5 EEG sets (designated as A to E), each containing 100 EEG sections. Collections A and B comprised EEG signals that have been taken from 5 healthy volunteers. The C and D sets referred to EEGs from patients with focal epilepsy (without ictal recordings) and the E set was derived from a patient with ictal recording. Support vector machines were used after applying principal components analysis or linear discriminant analysis over the features of the signals. MATLAB has been used to implement and tes t the proposed classification algorithm. To evaluate the proposed method, the confusion matrix, overall success rate, ROC, and the AUC of each class were extracted. K-fold cross-validation technique was used to validate the results. Results: The overall success rate achieved in this s tudy was above 82%. Dimension reduction algorithms can improve its accuracy and speed. Conclusion: It is helpful to be able to predict the occurrence of a seizure early and accurately. Using the computerized model represented in this s tudy could accomplish this goal.l ABSTRACT Article Info:
