This research aims to explain psychological well-being based on attachment to God and psychological well-being. Methods: Non-experimental research and its design were correlated. The statistical population included 328 students in Yasuj University. They were selected by multi-stage cluster sampling. After attending the classroom and obtaining satisfaction and providing the necessary explanations, a questionnaire was provided to them. From scales of attachment to God, Cricket Patrick, psychological well-being of Allen Watterman, and the feelings of shame and guilt of Tajni and Deiring. In this research, after collecting the data, using the questionnaire technique, the final data were extracted and analyzed using the software (Amos) version 24 (spss) version 18. Conclusion: Those who have a good attachment to God have a favorable psychological well-being. Also, analysis of the results showed that there is a positive and significant relationship between feeling of shame and sin with psychological well-being and attachment to God. Benjamin can be said that attachment to God and the feeling of shame and sin affects psychological well-being and mental health.

2011 The Journal of craniofacial surgery (Print)  
Özet Amaç: Paranazal sinuslar, allerjik hastalıklardan ve enfeksiyonlardan oldukça fazla etkilenen bölgeler olup bu bölgelerin morfolojik yapısının anlaşılması cerrahi olarak büyük önem arz etmektedir. Çalışmamızın amacı, bilgisayarlı tomografi (BT) kesitlerini kullanarak kadın ve erkek bireylerdeki sinus frontalis hacmini stereolojik olarak değerlendirmektir. Gereç ve Yöntem: Bu çalışma herhangi bir sinus frontalis hastalığı olmayan yaşları 20-60 arasında değişen 140 kişinin (70 erkek, 70
more » ... ) BT görüntüleri üzerinde yapıldı. Sinus frontalis hacimleri, koronal planda alınan kesitler üzerinde Cavalieri prensibi doğrultusunda planimetri metodu kullanılarak stereolojik olarak hesaplandı. Bulgular: Kadın ve erkek bireylerin verileri istatistiksel olarak karşılaştırıldığında, erkek bireylerin sinus frontalis hacimlerinin daha yüksek olduğu belirlendi. Kadınların sinus frontalis hacimleri ortalama olarak 4,04±1,84 cm 3 , erkeklerinki ise 7,02±2,78 cm 3 olarak bulundu. Tartışma: BT, manyetik rezonans ve üç boyutlu görüntüleme tekniklerinin kullanılmaya başlaması ile birlikte paranazal sinusların görüntülenmesinde de büyük ilerleme kaydedilmiştir. Çalışmamızda planimetri metodu kullanılarak erişkin bireylerdeki sinus frontalis hacimleri ölçülmüş ve erkek bireylerde belirgin olarak daha yüksek olarak saptanmıştır. Sinus frontalis yaygın asimetrik gelişim gösteren paranazal sinuslardan biri olduğu için hacminin araştırılması klinik olarak önem arz etmektedir. Sonuç olarak; sinus frontalis'in hacminin belirlenmesinin inflamatuar sinus hastalıkları, sinus frontalis travmaları ve endoskopik sinus cerrahisi açısından hekimlere önemli katkı sağlayacağı kanaatindeyiz. Abstract Aim: Paranasal sinuses are the anatomic regions that are frequently affected by allergic diseases and infections, thus it is substantial to comprehend the morphological structure of these regions for surgery. The aim of our study is to obtain stereological evaluation of frontal sinus volumes of female and male individuals by using computerized tomography (CT). Material and Method: This study assessed the CT images of 140 cases (70 male, 70 female) were at the age of 20 to 60 years and didn't have a disease of frontal sinus. Frontal sinus volumes were calculated stereologically on coronal plane sections by using planimetric method via Cavalieri principle. Results: When the data of male and female individuals were compared statistically; it was observed that frontal sinus volumes of men were larger. Average frontal sinus volume of women was 4,04 ±1,84 cm 3 and it was 7,02 ±2,78 cm 3 for men. Discussion: Significant advancement was obtained for paranasal sinus imaging by the use of CT, magnetic resonance imaging and three dimensional imaging techniques. In our study, frontal sinus volumes of adult individuals were measured by using planimetry method and it was detected significantly larger in men. Since frontal sinus is one of the paranasal sinuses that reveal asymmetrical development, it is clinically important to seek out its volume. In conclusion; we think that determination of the frontal sinus volume will make a major contribution to physicians for inflammatory sinus diseases, frontal sinus traumas and endoscopic sinus surgery.

The predictive role of aortic propagation velocity for coronary artery disease

Fereshteh Ghaderi, Hossein Samim, Faeze Keihanian, Seyed Ali Danesh Sani
2018 BMC Cardiovascular Disorders  
It is well recognized that cardio-vascular risk factors lead to histological and functional changes in aorta, and aortic stiffness is the best predictor of cardiovascular morbidity and mortality. In this study we evaluated the relation of a less evaluated echocardiographic parameter of aortic stiffness, aortic propagation velocity (APV) with the presence and severity of CAD. Methods: This cross sectional study was conducted from May 2015 to March 2016 in Imam Reza hospital, Mashhad, Iran.

Patients were divided into two sub-groups based on angiographic findings: patients with CAD (38 patients, 54.3%) and non-CAD (32 patients, 45.7%). Transthoracic echocardiography was performed using the conventional 2D and color M-Mode imaging. Aortic propagation velocity (APV), aortic strain (AS) and distensibility (AD) were measured. The presence and Severity of CAD (assessing by syntax score) and their relation with aortic stiffness indices were assessed. Results: Aortic strain (6.23 ± 1.93% versus 11.66 ± 4.86%, P < 0.0001), distensibility (2.46 ± 0.91 vs 5.57 ± 2.25 cm 2 dyn-110-3, P < 0.0001) and APV (48.63 ± 10.31 cm/sec vs 77.75 ± 9.97 cm/s, P < 0.0001) were significantly decreased in CAD group compared with non-CAD group. In our study, APV showed significant inverse relationship with CAD. Based on our results, APV less than 56 cm/sec could be used to predict CAD with sensitivity and specificity of 96.9 and 78.9% respectively. We also found an inverse correlation between APV and severity of CAD. Conclusion: Aortic strain, AD and APV (a less evaluated echocardiographic index) showed significant inverse correlation with presence and severity of CAD.

With the global outbreak of COVID-19 epidemic since early 2020, there has been considerable attention on CT-based diagnosis as an effective and reliable method. Recently, the advent of deep learning in medical diagnosis has been well proven. Convolutional Neural Networks (CNN) can be used to detect the COVID-19 infection imaging features in a chest CT scan. We introduce ai-corona, a radiologist-assistant deep learning framework for COVID-19 infection diagnosis using the chest CT scans. Method:
more » ... ur dataset comprises 2121 cases of axial spiral chest CT scans in three classes; COVID-19 abnormal, non COVID-19 abnormal, and normal, from which 1764 cases were used for training and 357 cases for validation. The training set was annotated using the reports of two experienced radiologists. The COVID-19 abnormal class validation set was annotated using the general consensus of a collective of criteria that indicate COVID-19 infection. Moreover, the validation sets for the non COVID-19 abnormal and the normal classes were annotated by a different experienced radiologist. ai-corona constitutes a CNN-based feature extractor conjoined with an average pooling and a fully-connected layer to classify a given chest CT scan into the three aforementioned classes. Results: We compare the diagnosis performance of ai-corona, radiologists, and model-assisted radiologists for six combinations of distinguishing between the three mentioned classes, including COVID-19 abnormal vs. others, COVID-19 abnormal vs. normal, COVID-19 abnormal vs. non COVID-19 abnormal, non COVID-19 abnormal vs. others, normal vs. others, and normal vs. abnormal. ai-corona achieves an AUC score of 0.989 (95% CI: 0.984, 0.994), 0.997 (95% CI: 0.995, 0.999), 0.986 (95% CI: 0.981, 0.991), 0.959 (95% CI: 0.944, 0.974), 0.978 (95% CI: 0.968, 0.988), and 0.961 (95% CI: 0.951, 0.971) in each combination, respectively. By employing Bayesian statistics to calculate the accuracies at a 95% confidence interval, ai-corona surpasses the radiologists in distinguishing between the COVID-19 abnormal class and the other two classes (especially the non COVID-19 abnormal class). Our results show that radiologists diagnostic performance improves when incorporating ai-coronas prediction. In addition, we also show that RT-PCRs diagnosis has a much lower sensitivity compared to all the other methods. Conclusion: ai-corona is a radiologist-assistant deep learning framework for fast and accurate COVID19 diagnosis in chest CT scans. Our results ascertain that our framework, as a reliable detection tool, also improves experts diagnosis performance and helps especially in diagnosing non-typical COVID-19 cases or non COVID-19 abnormal cases that manifest COVID-19 imaging features in chest CT scan. Our framework is available at:

Seropositivity of HCV in female was higher than male (14.1 % versus 10.4%, respectively) but the difference was not statistically significant (p = 0.52). No significant relationship was seen between Anti-HCV seroprevalence and demographic factors such as age, place of residence and marital status. The seroprevalence of co-infection with HBV and HCV in our study was higher than such reports from some colllltries (Italy); but it was in line with worldwide prevalence (> 10% ). A careful longitudinal evaluation of the viremia levels of both HBV!HCV viruses is essential for making a correct diagnosis and tailoring the appropriate therapeutic schedule in co-infected patients.

In our previous paper which was presented in ICFCC2009 Conference in Kuala Lumpur and published by IEEE Computer Society [1], we explained the structure of WEP as a first wireless security standard and discussed all its versions, problems and improvements. Now, we try to explain all of WPA versions and problems with the best solutions and finally make a comparison between WEP and WPA. Then we are in the next phase which is to explain the structure of last standard (WPA2) and we hope that we will publish a complete comparison among wireless security techniques in the near future and recommend a new proposal as a new protocol.

With doing this, search engines store each site's tables in their databases and implement their ranking results on them. Thus, accuracy of data in every table (and its being up-to-date) is ensured and no 404 result is shown in search results since, in fact, this data crawler crawls data entered by webmaster and the database stores whatever he wants to display. Keywords exclusive crawler, search engine, crawler, database 1.Introduction Searching is a daily activity of many people. Individuals deal with this task every day. The need to search enhances along with the increasing demand for more knowledge and information. Also, in computer science search and communication are among most important items so that they can be seen in most applications, programs and even on the web and Internet. Nowadays the Internet contains millions of information containing pages. Knowing a site's address users can connect it and use its resources and information. In order to reach this huge information resource human has began to increasingly use search engines. For this reason search engines repeat their crawling, ranking and indexing operations every day. [12] Among these daily operations crawling specifies the most basic function of a search engine. The biggest search engines of the world do this operation in offline mode (query is not accomplished while entering but it is already done) [16] and its optimization does not influence response received by the user but better results can be embedded in the database through optimization.

Hepatitis D virus (HDV) is a defective RNA virus dependent on hepatitis B virus (HBV) infection for its replication and expression. It is known that coexistent infection with HDV tends to aggravate the course of HBV-associated liver disease. This study was carried out to determine the seroprevalence of HDV among hepatitis B surface antigen (HBsAg)-positive individuals in the northeast part of Iran. 139 HBsAg-positive subjects detected from a population-based single stage cluster sampling in

Logistic regression was used to determine the relationship between independent variables and HDV seropositivity. Of 139 cases, 68 were males (48.9%) and 71 were females (51.1%). The mean age was 41.9 +/- 11.3 years (range, 25-64 years). Anti-HDV antibody was positive in 8 subjects (5.8%), with a female predominance (9.9% vs 1.5%, p=0.06; odds ratio, 7.32; 95% confidence interval, 0.87-61.23). No significant relationship was seen between anti-HDV seropositivity and demographic factors such as age, place of residence and marital status. These findings show that HDV infection is endemic in Golestan province (northeast) of Iran. Seroprevalence of anti-HDV in the present study was higher than in some previous studies from other parts of Iran. Our results suggest that the prevalence of HBV/HDV coinfection in Golestan province of Iran has increased during the last decade. Therefore, practitioners and health care managers should be made aware of the risk of dual infection with HBV and HDV.
