An ellipse framework for precise iris edge detection

Iris segmentation is the principal task of Iris based biometric identification systems. Always the low contrast between pupil and iris always affects on accuracy of detecting boundary between them. In order to increasing using a difference function and a factor matrix. We also enhance the technique to detect the pupil and iris as ellipse instead of circle. Experiments show that the proposed technique can segment the iris region and pupil region precisely. Based on our result, 99.34% of eyes have been segmented accurately in 1.24s averagely

Lower Urinary Tract Symptoms in Patients with COVID-19: Results of a Cross-sectional Study

Objective: We aimed to investigate the effect of severe acute respiratory syndrome-coronavirus-2 infection on lower urinary tract function using validated questionnaires in patients with patients. Materials and Methods: This descriptive cross-sectional study was conducted according to the inclusion and exclusion criteria on 709 patients with Coronavirus disease-2019 (COVID-19) on an outpatient basis from September 2020 to May 2021 in Kerman’s health centers. After signing the consent form and completing the demographic information, the International Consultation on Incontinence Questionnaire male Lower Urinary Tract Symptoms Modules and International Consultation on Incontinence Questionnaire Female Lower Urinary Tract Symptoms questionnaires were completed. Finally, the data were analyzed using the SPSS version 26 software. Results: Patients with COVID-19 (n=709) (365 questionnaires related to women and 344 questionnaires related to men) were examined on an outpatient basis. In general, 42.2% of women and 45.6% of men with COVID-19 had nocturia. The frequency of urination per day was higher than normal in 23% of women and 40.4% of men. In addition, 15% of women complained of a sense of urinary urgency while urinating, and 13.7% and 20% of men complained of straining and hesitancy in urinating, respectively. Similar to the males, the common symptoms in women were nocturia and increased daily frequency. In addition, with increasing age, lower urinary tract symptoms (LUTS) became common in COVID-19 patients. Conclusion: The results of our investigation imply that people with COVID-19 may acquire or experience de novo LUTS, particularly storage symptoms. All symptoms were more in people over 50 years old than in those younger. COVID-19 infection should be investigated in any patient presenting with LUTS during the current pandemic. Further research is needed to clarify the exact pathophysiology of this correlation

Comparison of behavioral problems between the children with one schizophrenic parent and children with healthy parents

Introduction: The quality of relationship between children and parents in the early years of life is one of the most effective factors in the mental growth of the children. A parent being affected by schizophrenia may have very deep effects on the mental growth of the children. This study aimed to compare the behavioral problems in the children with one schizophrenic parent and children with healthy parents. Material and methods: This descriptive study was performed in Zahedan, Iran in 2014-2015. The behavioral problems of 60 children with a schizophrenic parent were compared to that of 60 children with healthy parents. The Child Behavior Checklist (CBCL) was used to evaluate the two groups. Results: The comparison of the CBCL score between two groups showed a significant difference (P < 0.005). Moreover, the CBCL score of primary school girls (P = 0.03) and boys (P = 0.04) was significantly different between the two groups. No significant difference was reported between the two groups regarding the CBCL score of teenage girls (P = 0.09) and teenage boys (P = 0.09). Conclusions: Our findings can be regarded as evidence supporting the effect of psychotic disorders, such as schizophrenia in parents on the behavioral problems of children

Iris segmentation and normalization approach

Iris is a desirable biometric representation of an individual for security-related applications. However the iris segmentation and normalization process is challenging due to the presence of eye lashes that occlude the iris, the dilation of pupils due to different light illumination and several other uncontrolled factors. In this work, we enhanced Daugman method to locate the iris and normalized it from polar to Cartesian coordinate. Iris is located by using a variable parameter binning approach. The algorithm is tested using iris images from CASIA database and MMU database. The percentage detection on MMU iris database is 99% and that of CASIA is 98%. Our approach is feasible to produce an iris template for identity identification and biometric watermarking application

Secure multi party computation algorithm based on infinite product series

Nowadays, data mining has been extremely interested; because of its ability to give the companies a better view for strategic decisions. In case of, contribution of several companies for a shared data mining, there is a big problem: confidentially of data. Here, the companies are avoided passing their data to the miner directly. The best solution is applying a cryptographic tools named as Multi Party Computation (MPC). In this paper, we represent a secure MPC algorithm for online transactions, where the clients' information, especially joint time and public keys are not clear. The algorithm emerges the excessively useful response time. The mathematic demonstration also ensures the privacy of clients' data

Assessment of mothers’ behavior in preventing febrile convulsion in their children in Arak City: an application of Health Belief Model

Introduction:Febrile convulsion constitutes the most common neurologic disorder, as well as the most common type of convulsion, in children under 6 years of 6. Considering the crucial role of mothers in controlling the disease, as well as the troubling nature of the disease itself, we conducted the present study to assess the behavior of mothers in Arak city regarding prevention of febrile convulsion based on the Health Belief Model.Material and Methods:This is a cross-sectional study on 100 mothers with children under two years of age, referring to healthcare centers in Arak. Data were collected using a questionnaire based on the Health Belief Model (perceived susceptibility, severity, benefits and barriers, and cues to action) and a checklist of mothers’ function in preventing febrile convulsion in their children.Results:The findings of the present study indicated that mothers with poor function had significantly higher levels of perceived barriers compared to others. Moreover, function was significantly lower for illiterate mothers or those with elementary education compared to others. In addition, mothers with lower education and poor function had lower levels of perceived susceptibility (p<0.05).Conclusion:Since most mothers in our study functioned poorly in preventing febrile convulsion, which may be improved with increased awareness, and perceived susceptibility, severity and benefits and decreased perceived barriers, it is recommendable to consider an elaborate educational program based on the Health Belief Model for mothers in order to enhance their children’s health
