Objective: Knowledge is an asset that increases when others share it, and its sharing and dissemination leads to synergy and growth of individual and collective knowledge. In fact, the dissemination of knowledge is the process of communication between two or more people, which includes the transfer and acquisition of knowledge. In knowledge dissemination, the focus is on human capital and interpersonal interactions. In recent years, the expansion of social media has had a significant impact on the ease of spreading knowledge among people. Social media are central members of internet communities that have many possibilities to create interpersonal communication and transfer information and dissemination knowledge. Today, social networks have become a valuable platform to facilitate knowledge sharing and communication, not only at a personal or individual level, but also for organizations. However, despite the significant and rapid growth of research in this field, few attempts have been made to systematically review and synthesize the findings of previous reviews and evaluate the current state of research on the use of social networks in knowledge dissemination. The main purpose of this paper is to provide a better understanding and review the current state of research on the use of social networks for knowledge dissemination.Methodology: In this research, a systematic literature review method has been used to collect and review studies by following a predefined review method, integrating automatic and manual search strategies, in order to cover all related research articles published in this period of time. Systematic search according to keywords reached 253 research outputs, and finally 37 research outputs matching the criteria were determined for in-depth analysis.Findings: After the data analysis process, the results from the selected preliminary studies show a clear and comprehensive overview of current research that focuses on knowledge dissemination through social networks and identify three main activities of social network use, which include the processes of knowledge seeking, knowledge dissemination and social interaction. In addition, factors including accessibility, authenticity, and permanence make social networks a space for knowledge dissemination in all fields. The findings of this study show that organizational conditions, lack of leadership, costs of knowledge compilation, fear of losing the power of knowledge and lack of personal benefit are among the challenges of knowledge dissemination in social networks.Conclusion: The results of this study show that social networks for implementing knowledge sharing are related to different forms of behavior and have the potential to overcome the challenges associated with its use.

Background: The current advances in radiotherapy (RT) have improved the outcome of breast cancer (BC) patients. Despite its therapeutic benefits, the iatrogenic toxicities of RT and its impact on BC survivors are still debated, and further evaluations should be considered. This study aims to assess the rate of subclinical hypothyroidism and hypoparathyroidism among BC patients who were exposed to therapeutic radiation. Methods: Seventy females undergoing RT for BC were enrolled in this cross-sectional study. Laboratory assessment of thyroid stimulating hormone (TSH), free thyroxine (fT4), and free triiodothyronine (fT3) levels was obtained to evaluate thyroid function. The parathyroid function was evaluated by measuring serum levels of Calcium (Ca), Phosphorus (P), and parathyroid hormone (PTH) at baseline, six and 12 months after RT. Results: The mean age of patients was 54.3±6.4 years. We found no cases of hypothyroidism before radiotherapy. However, nine patients developed hypothyroidism in the six months after radiotherapy (one clinical and eight subclinical, 13% in total), and six patients were identified with hypothyroidism in the 12 months after radiotherapy (one clinical and five subclinical, 8.7% in total). Significant relationships were observed in the hypothyroidism rate at both six months (p = 0.003) and 12 months (p = 0.028) after RT compared with the baseline. There was no case of hypoparathyroidism before and after RT. Conclusion: In summary, we found that thyroid and parathyroid dysfunction after RT are relatively common findings among women with BC. It is a treatable source of morbidity in patients undergoing RT. Therefore, routine thyroid function monitoring should be recommended to improve the quality of life in BC survivors.

Contexte : Les progrès réalisés en radiothérapie ont amélioré le sort des patientes atteintes de cancer du sein. Malgré ses avantages thérapeutiques, la radiothérapie a des effets toxiques iatrogènes et des répercussions sur les survivantes du cancer du sein qui font toujours l’objet de débats, et qui méritent qu’on s’y attarde. La présente étude vise à évaluer les taux d’hypothyroïdie infraclinique et d’hypo­parathyroïdie chez les patientes atteintes de cancer du sein ayant reçu de la radiothérapie. Méthodologie : Pour l’étude, de type transversal, on a recruté 70 femmes sous radiothérapie pour traiter un cancer du sein. La fonction thyroïdienne a été évaluée par un examen de laboratoire mesurant les taux de thyréostimuline (TSH), de thyroxine libre (T4) et de triiodothyronine libre (T3). La fonction parathyroïdienne a été évaluée par mesure des taux sériques de calcium (Ca), de phosphore (P) et d’hormone parathyroïdienne (PTH) avant le traitement, puis 6 mois et 12 mois après la radiothérapie. Résultats : L’âge moyen des patientes était de 54,3 ± 6,4 ans. Aucun cas d’hypothyroïdie n’a été décelé avant la radiothérapie. Cependant, une hypothyroïdie est apparue chez 9 patientes dans les 6 mois suivant la radiothérapie (1 cas clinique et 8 cas infracliniques, donc 13 % au total), et on a diagnostiqué une hypothyroïdie à 6 patientes dans les 12 mois après la radiothérapie (1 cas clinique et 5 cas infracliniques, donc 8,7 % au total). Des relations significatives ont été observées dans les taux d’hypothyroïdie entre les mesures prises 6 mois (p = 0,003) et 12 mois (p = 0,028) après la radiothérapie et les mesures de départ. On n’a constaté aucun cas d’hypoparathyroïdie avant ou après le traitement. Conclusion : En résumé, on observe que le dysfonctionnement thyroïdien et parathyroïdien après la radiothérapie est relativement fréquent chez les femmes atteintes de cancer du sein. Il s’agit d’une cause de morbidité traitable. Par conséquent, un contrôle systématique de la fonction thyroïdienne est à recommander pour améliorer la qualité de vie des survivantes de cancer du sein.

Objective: The current research seeks to identify and analyze the most important trust-building factors affecting the sharing of organizational knowledge in the field of knowledge management to provide the basis for proper management and proper planning for managers of organizations.Methodology: The present research was conducted using the methods of Systematic Review and Delphi. The participating experts in Delphi were selected by purposive sampling. The selected experts were professors of information and knowledge science, sociology, and management in university with scientific and research experience in knowledge management and organizational trust. In order to analyze the data, frequency distribution, mean, agreement coefficient, one-sample t-test, and Friedman ranking were used.Findings: The research findings showed that the trust-building factors affecting knowledge sharing could be categorized into six general dimensions, including organizational trust factor, mental norm, and attitude towards knowledge sharing, external motivation, internal motivation, and organizational support. Among the effective factors from the point of view of experts, the factor of organizational trust, with a total Mean of 4.86, has the most impact, and external motivation, with a total Mean of 4.14, has the least impact on knowledge sharing. The effects of the factors on the components of knowledge sharing also showed that the effect of organizational trust on the intention to share knowledge, with an average of 4.91 and a consensus index of 1.9, has the highest average and value of the consensus index, Vice versa, the effect of the external motivation factor on the component Knowledge sharing behavior has the lowest value with an average of 4.09 and a consensus index equal to 1.38. Also, the factor prioritization index results showed that the organizational trust factor has the first rank with a Mean rating of 4.45. After that, the factor of internal motivation and attitude to knowledge sharing with a similar Mean rank equal to 3.77 in the second rank, the factor of organizational support with a Mean rank equal to 3.50 in the third rank, the Mental norm factor with a Mean rank equal to It ranks fourth with 23.3 and external motivation factor ranks fifth with a Mean rating of 2.27.Conclusion: The results showed that for efficient knowledge sharing and creating a dynamic platform, the attention and appropriate policy of managers and knowledge management professionals to improve the culture of knowledge sharing among different organization departments seems necessary. In this regard, organizations are suggested to facilitate employee knowledge-sharing by strengthening trust-building factors and motivational stimuli.

Background: “JD is imminent and likely paradoxical reactions against self perceived threat to keep of self in modification for elimination of the opponent mentally or physically”. Assailants’ attention is "a data directive system with quantifying less hot cognition and the least of data collections in the fight-or-flight response”; victims’ attention "a data directive system with quantifying more hot cognition and the most data collections in the fight-or-flight response”. We compare explicit and implicit evaluations of the JDAS. Method: We selected 1089 participants for neutral facial patterns normalization, normal finds participants, and neuropsychological doing tasks with quota, convenience, and Poisson samplings, respectively. Samples are collected in three Iran’s provinces. 100 subjects participated with an analogue method to normalize 400 neutral pictures in likeness of Iranians and attractiveness of faces. 989 subjects carried out Millon Clinical Multiaxial Inventory (MCMI II) to find normal participants for the third step. 100 subjects did tasks to compare and evaluate JDAS agents. Results: Participants evaluated 400 pictures to determine 120 attractiveness of faces and likeness of Iranian pictures using an analogue method. The results showed: In explicit assessments, only "I" sense of self showed significant differences among general participants, though it was less severe. General implicit assessments indicated significant differences among the senses of self related to nationality, denomination, and "I," respectively. Guilty implicit assessments revealed significant differences among three senses of self: nationality, denomination, and "I," respectively. Both explicit and implicit assessments of the JDAS for victim and assailant agents showed significant differences. Conclusions: Threatening information against self agents strengthens endangered parts of the self. Normal criminals exhibit less empathy towards victims. Denomination, nationality, and "I" self agents are found to be independent self agents. It highlights the complexity of self-identity, revealing socially, and roles of social and cognitive factors in shaping attitudes towards JD.

Software evolution and continuous changes make maintenance difficult, reducing the quality of software structure and architecture. To cope with this challenge, re-modularization is used to promote the modular structure of software system by the re-grouping of software elements. In this paper, the proposed method recognizes various dependencies in terms of an objective function unlike what has been stated in some other methods. In this method, a search-based many-objective fitness function is proposed to formulate re-modularization as an optimization problem. The results of the proposed method have been compared to the effects of four other methods based on MQ and NED. The results show the proposed method improved re-modularization remarkably compared to others in terms of both MQ and NED criteria especially for smaller software. Therefore, the proposed method can be effective in redefining real-world applications.

Introduction: IUI or injection of washed sperm into the uterine cavity is one of the assisted reproductive techniques that has been widely used in the treatment of infertility. This study was performed with aim to evaluate the effect of intrauterine injection of granulocyte stimulating factor (G-CSF) on the success rate of IUI in patients referred to the infertility center of Ardabil University of Medical Sciences.Methods: This clinical trial study was performed in 2019-2020 on 100 women with primary infertility referred to the Infertility Center of Ardabil University of Medical Sciences for IUI. The subjects were randomly divided into intervention and control groups each with 50 women. To stimulate ovulation for the women in two groups, clomiphene citrate was administered from the third to the fifth day of menstruation at a dose of 50-100 mg daily for five days and gonadotropin ampoules were administered with dose 150 mg at days 7 and 9 and after reaching to at least one follicle with 20 ml diameter, HCG was injected for the final maturation of the oocyte. In the intervention group, in addition to previous procedures on the day of HCG injection, 100 micrograms of G-CSF was injected intrauterine with IUI catheter, and then IUI was performed 36 hours later. Collected data were analyzed by SPSS (version 25). P

IntroductionThe emergence of the web facilitated the retrieval of information. This made libraries as one of the most important centers of information considering the web for the information retrieval process. However, the fast change of the web leads to the transformation of library functions. The semantic web is an opportunity for libraries to change their functions. Linked data as a method in the semantic web can make a major change in library functions. It can improve the discoverability, visibility, and interoperability of the resources. For example, all libraries use authority controls for organizing their information. But using authority controls in a traditional way can be challenging. Therefore, using the web can help libraries tackle these potential challenges and problems. Transforming authority data into linked data which seems an innovative and faster way for finding the resources can be a step forward for libraries and users. This paper aims to design a framework for transforming the National Library of Iran Subject Headings into linked data and publish them on the web. Literature ReviewDesigning and proposing a framework for linking the data was the topic of some research papers. Linking the university data (Behkamal et al., 2011) linking and visualizing medicine information (Sekhavati, Farahi, & Jalali, 2011) web objects (Hosseini, 2020), table data (Mulwad et al., 2010), Industrial Data (Graube et al.,2012), and government data (Villazón-Terraza, Vilches-Blázquez, Corcho, & Gómez-Pérez, 2011; Mulwad, Finin, & Joshi, 2011) were the topics for some reviewed studies. The results of their studies indicated that in general, linked data could improve information retrieval. Implementing a linked data method in library data was discussed in some papers. Kar & Das (2020) designed a methodology for linking bibliographic information in a digital repository. Similarly, Ryan et al. (2015) examined the linking of place names in a dataset, transferring them into RDF and linking them with other similar datasets. Summers, et al (2008) provide a methodology for transferring subject headings into linked data. their results showed that transferring LCSH into SKOS affects information retrieval. The linking and publishing National Library of Iran data were also investigated by Eslami & Vaghefzadeh (2013). Fathian Dastgerdi et al (2020) tried to make a pattern for linking data in library systems. They examined the components which are needed for implementing the linked data method in library systems. Their result showed that using linked data in library systems affects the visibility of bibliographic metadata. Based on the reviewed studies, many international papers discussed publishing library linked data in theoretical and practical ways. Whereas studies done in Iran focusing on linked data mostly developed patterns and models for linking data (e.g., Fathian Dastgerrdi; 2020). Few Persian studies were done for publishing bibliographic data (e.g., Eslami & Vaghefzadeh, 2013; Sekhavati, 2011). Although there is a significant number of papers discussing linked data, the technical aspect for publishing and linking library data was rarely examined. To fill this gap, this study aims to develop a framework for publishing National Library of Iran subject headings which is unlike Fathian Dastgerdi et al., (2020) paper considers the technical tools and aspects and unlike Sekhavati’s (2011) paper examines the Persian subject headings. MethodologyThis research is an applied study that utilizes a library method for designing a publishing framework. Linked data was implemented to ensure the possibility of publishing the research data. First, Persian subject headings which are represented in Iran MARC format were obtained in Marc XML files From the National Library of Iran. Then the method for transferring and publishing the data was applied. Results The framework developed in this research collected National Library of Iran subject headings randomly. The selected data were first cleaned by Microsoft Excel and MarcEdit. In the next step, cleaned data were converted into RDF Using OpenRefine. The study’s project was imported to Open Refine software, linked with external datasets, and saved in a triple store. Finally, the linked subject headings were displayed through the Skosmos interface.DiscussionPublishing library data as linked data is an example of utilizing Web 3 in library systems. National libraries worldwide have tried linking their data including subject headings with other datasets. However, there remains a gap in publishing linked Persian subject headings and to the best of the authors' knowledge it seems that no paper has pointed to technical aspects of implementing Persian subject headings. ConclusionThe current paper has transformed the Persian subject headings into a linked dataset in an RDF turtle format. Then, it visualized the linked data in the Skosmos interface. But there can be some limitations to this study. Using OpenRefine was reported successfully in this paper, but it seems that there may be a problem in data with larger sizes. In conclusion, since this framework improve the retrieval of authority data in this research, it can be used for publishing National library of Iran subject headings.

Abstract Background Chronic Kidney Disease (CKD) patients often require long-term care, and while Hemodialysis (HD) is the standard treatment, Comprehensive Conservative Care (CCC) is gaining popularity as an alternative. Economic evaluations comparing their cost-effectiveness are crucial. This study aims to perform a cost-utility analysis comparing HD and CCC using the EQ-5D-5L and ICECAP-O instruments to assessing healthcare interventions in CKD patients. Methods This short-term economic evaluation involved 183 participants (105 HD, 76 CCC) and collected data on demographics, comorbidities, laboratory results, treatment costs, and HRQoL measured by ICECAP-O and EQ-5D-5L. Incremental Cost-Effectiveness Ratios (ICERs) and Net Monetary Benefit (NMB) were calculated separately for each instrument, and Probabilistic Sensitivity Analysis (PSA) assessed uncertainty. Results CCC demonstrated significantly lower costs (mean difference $8,544.52) compared to HD. Both EQ-5D-5L and ICECAP-O indicated higher Quality-Adjusted Life Years (QALYs) for both groups, but the difference was not statistically significant (p > 0.05). CCC dominated HD in terms of HRQoL measures, with ICERs of -$141,742.67 (EQ-5D-5L) and -$4,272.26 (ICECAP-O). NMB was positive for CCC and negative for HD, highlighting its economic feasibility. Conclusion CCC proves a preferable and more cost-effective treatment option than HD for CKD patients aged 65 and above, regardless of the quality-of-life measure used for QALY calculations. Both EQ-5D-5L and ICECAP-O showed similar results in cost-utility analysis.

Background: “Justified Death Attitude (JDA) is imminent and likely paradoxical behavior against self threat to keep of self in modification for elimination of the opponent mentally or physically”the first author defined. The former studies have indicated that Justified Death Attitude Scale (JDAS) has both validity and reliability of the young majority society Shia, but we do not know whether or not it is a valid or reliable scale of minority societies Sunni, Assyrian and the old generation. If it has, can the scale discriminate between the JDA and the poll? Objectives: It is a cross-sectional study to evaluate development of JDAS comprehensively because different generations, multi ethnicities, and social variables affect attitude and cognition persistently. Method: 744 participants (368 male and 376 female) were selected through the convenience sampling method in Tehran, Ilam, Khoram Abad, and Sanandaj. The participants were of the following demographic properties: 528 adult and 216 older adult participants; 538 Shia, 108 Sunni, and 98 Assyrian participants; 460 normal and 284 abnormal participants. Participants carried out the General Health Questionnaire-12 (GHQ-12) and JDAS. 115 answer sheets were cancelled (less than 5%). Results: A Pearson product-moment correlation coefficient, binomial tests, Chi square tests, and Jonckheere-Terpstra tests are performed to analyze the data. Multiethnic studies indicate that JDAS is a valid scale for adult and older adult participants and Shia, Sunni, and Assyrian participants (p>0.05). Meanwhile, attitude and polls are two different phenomena in the collision between capital punishment, the kind of death penalties, the agreement of euthanasia, and kind of euthanasia %61, %57, %56, and %61, respectively, because of different propositional and associative processes. The Chi-square indicates that gender, generations, ethnics, and sanity influence polls significantly. In line with the ethnic model of JDA, ethnics influence legal and medical subscales significantly according to Jonckheere-Terpstra tests. Conclusion: The bases of polls and attitude are conformity and self, respectively. So, the poll coefficient of error is very high to assess social ideas. Although you could find some similarities between polls and attitude, they are different phenomena principally.

Background: Justified Death Attitude (JDA) is a new term about one’s agreement with killing someone else. Previous studies have shown the Justified Death Attitude Scale (JDAS) is valid and reliable. We also know that some variables like major and gender are associated with JDA, but we do not know how gender, ethnics, generation, and sanity differently would affect JDA. Objectives: This was a cross-sectional study to evaluate the effect of ethnics, generation, gender, and sanity on the attitude of the people about justified death. Method: In 2022, 744 participants, including 368 male and 376 female participants were selected through convenience sampling method in Tehran, Ilam, Khorramabad, and Sanandaj. Participants were stratified according to age (528 adults, 216 older adults), religion (538 Shiite, 108 Sunni, and 98 Assyrian participants), and sanity status (460 normal and 284 participants with possible mental illness). Participants filled out General Health Questionnnair-12 (GHQ 12) and Justified Death Attitude Scale (JDAS). Results: Older, Shiite, and Sunni participants agreed more with death penalties, but younger and Assyrian participants disagreed more with death penalties. Furthermore, young, Assyrian agreed more often with euthanasia. Different generations think significantly differently about the type and severity of execution and euthanasia. Conclusion: The more diverse the sociocultural background, the more different is the attitude about justified death. That might be due to dissimilar crystallization of sense of self in different socio-cultural backgrounds and through different cognitive processes.

Background: Helicobacter pylori infection is a major risk factor for gastric cancer in Iran, but the impact of socioeconomic factors on its prevalence is poorly understood. This study aimed to assess the socioeconomic inequalities and risk factors associated with H. pylori infection in Iran. Methods: This cross-sectional study was conducted based on the PERSIAN cohort study. A total of 20460 individuals aged 35 to 70 years in Ardabil, Iran were included in the study. H. pylori infection was determined based on stool tests and clinical records. Multilevel logistic regression models with random intercepts at household and community levels were used to identify risk factors associated with H. pylori prevalence. The concentration index (CIn) and concentration curve (CC) were employed to assess socioeconomic-related inequality. Results: In this study, 70.4% (CI 69.6–71.0) of the participants were infected with H. pylori, with a higher prevalence in women (71.2%) than men (69.6%). Age (OR: 1.37, CI: 1.17-1.61), sex (OR: 1.20, CI: 1.12-1.28), level of education (OR: 1.33, CI: 1.17-1.49), cardiac disease (OR: 1.32, CI:1.18-1.46), and BMI groups (OR: 2.49, CI: 1.11-5.58) were significantly associated with H. pylori infection based on the multivariable logistic regression. The results of the CIn and CC indicated that H. pylori were more prevalent among economically disadvantaged groups (CIn: -0.1065; [-0.1374 to -0.0755]). Conclusion: The prevalence of H. pylori in Iran is higher than in other developing countries, and significant socioeconomic inequality exists between the poor and the rich. To reduce the rate of gastric cancer, socio-economic and demographic factors, especially the poor and people with low levels of education, should be considered.

Regression testing reduction is an essential phase in software testing. In this step, the redundant and unnecessary cases are eliminated, whereas software accuracy and performance are not degraded. So far, various researches have been proposed in regression testing reduction field. The main challenge in this area is to provide a method that maintain fault-detection capability while reducing test suites. In this paper, a new test suite reduction technique is proposed based on data mining. In this method, in addition to test suite reduction, its fault-detection capability is preserved using both clustering and classification. In this approach, regression test cases are reduced using a bi-criteria data mining-based method in two levels. In each level, the different and useful coverage criteria and clustering algorithms are used to establish a better compromise between test suite size and the ability of reduced test suite fault detection. The results of the proposed method have been compared to the effects of five other methods based on PSTR and PFDL. The experiments show the efficiency of the proposed method in the test suite reduction in maintaining its capability in fault detection.

Background and Objective: Anal fissure can be associated with trauma caused by passing hard stools or prolonged diarrhea. The present study aimed to determine the effectiveness of topical hydrocortisone in the treatment of anal fissures in patients under medical treatment referred to Fatemi Hospital and Kausar Clinic of Ardabil Medical Sciences, Ardabil, Iran, in 2019. Materials and Methods: In this clinical trial study, 200 patients with anal fissures were randomly divided into two groups. The intervention group was treated with diltiazem gel, psyllium powder, lactulose syrup, and hydrocortisone topical ointment. Hydrocortisone ointment was not used in the control group. Results: The mean scores of initial pain were 8.06±0.7 and 7.79±1.02 in the intervention and control groups, respectively. The mean pain at the end of the first week was 2.5±1.06 in the intervention group and 3.34±0.89 in the control group. Pain reduction was significantly higher in the intervention group than in the control group in the first week of treatment. Two weeks later, the pain was 1.46±0.7 in the intervention group and 1.86±0.74 in the control group. There was a significant difference between the two groups in the first and second weeks of treatment. Conclusion: The therapeutic combination of a topical corticosteroid with a calcium channel blocker at the beginning of treatment for chronic fissures during the first week of treatment led to a faster response in the form of pain reduction

Background and purpose: Antibacterial properties of restorative materials are of great advantage as they control the progression of tooth decay. The use of self-adhesive composite materials has some benefits such as easier application and reduced treatment time. Because the antibacterial properties of restorative materials can play an important role in preventing secondary decay, especially in cervical restorations, this study was designed to evaluate the in vitro antibacterial activity of self-adhesive flowable composite against Streptococcus mutans. Materials and methods: An in vitro study was performed using 9 discs for each composite and glass ionomer group. The discs were prepared in three groups: micro-hybrid flowable composite samples, self-adhesive flowable composite samples, and self-curing glass ionomer samples. Direct contact test was used to compare the antibacterial properties of the discs. Data collection was done by direct contact test and visual counting of grown bacterial colonies. Data were recorded in a checklist developed according to the objectives of the study and analyzed using One-way ANOVA and Independent T-test in SPSS V22. Results: Findings showed that the antibacterial effect of glass ionomer was greater than that of flowable micro-hybrid composite and self-adhesive flowable composite. Also, a significant difference was observed between the antimicrobial activity of flowable microhybrid composite and self-adhesive flowable composite against Streptococcus mutans (P

Background: Good health requires healthy eating. However, individuals with eating disorders, such as anorexia nervosa, require treatment to modify their dietary behaviours and prevent health complications. There is no consensus on the best treatment practices and treatment outcomes are usually poor. While normalising eating behaviour is a cornerstone in treatment, few studies have focused on eating and food-related obstacles to treatment. Objective: The aim of the study was to investigate clinicians’ perceived food-related obstacles to treatment of eating disorders (EDs). Design: Qualitative focus group discussions were conducted with clinicians involved in eating disorder treatment to get an understanding of their perceptions and beliefs regarding food and eating among eating disorder patients. Thematic analysis was used to find common patterns in the collected material. Results: From the thematic analysis the following five themes were identified: (1) ideas about healthy and unhealthy food, (2) calculating with calories, (3) taste, texture, and temperature as an excuse, (4) the problems with hidden ingredients and (5) the challenges of extra food. Discussion: All identified themes showed not only connections to each other but also some overlap. All themes were associated with a requirement of control, where food may be perceived as a threat, with the effects of food consumption resulting in a perceived net loss, rather than a gain. This mindset can greatly influence decision making. Conclusions: The results of this study are based on experience and practical knowledge that could improve future ED treatments by enhancing our understanding the challenges certain foods pose for patients. The results may also help to improve dietary plans by including and explaining challenges for patients at different stages of treatment. Future studies could further investigate the causes and best treatment practices for people suffering from EDs and other eating disturbances.

Background: Women often have many reproductive health problems in developing countries. Economic and social factors play a vital role in health outcomes. This study aimed-predict women’s reproductive health from socio-economic status in Ardabil City, Iran in 2020. Methods: A cross-sectional study was conducted based on a prospective cohort study in Ardabil in March 2020. Out of 9,000 eligible participants (35-70 years old and living in Ardabil), 368 women were included in the study with systematic random sampling. A checklist was used-collect all patient information from the Ardabil Persian Cohort study. Data were analyzed using descriptive statistics, logistic regression, and multivariate regression analysis. The significance level was 5%. Data were examined using statistical SPSS software, version 21. Results: The results showed a significant statistical relationship between socio-economic status and women’s reproductive health (P

Introduction and Objectives: Nowadays, it is essential to use narrow diameter implants in reduced bone thickness. Due to controversies in previous research, the present study was conducted to evaluate the success rate of narrow diameter implants (2.4 mm and 3 mm) in a single tooth in the anterior region after one year of loading.Materials and Methods: In this historical cohort study, groups under investigation included patients who received single-tooth implants in the anterior edentulous segment without bone graft [40 patients with implants 2.4 mm in diameter (IMTEC, USA) and 3 mm in diameter (MILO, USA), n=20]. During the follow-up period of one year, bone resorption, pain, numbness, mobility, esthetic, peri-implant radiolucency, probing depth, and gingival index were evaluated. The Fisher’s exact test and T-test were used to analyze aesthetic scores while the Mann-Whitney test and the Wilcoxon Signed Ranks Test were employed to compare gingival index values.Results: In this research, no discernible bone resorption, peri-implant radiolucency, pain, and numbness was found, and only in five implants, prostheses lacked esthetic, according to pink esthetic scores. The total survival rate and success rates were 100% and 98.3% respectively.Conclusion: Within the limitationS of this study, narrow diameter implants replacing the anterior teeth (for proper case selection and ideal occlusion) is a successful treatment plan with a high survival and success rate.

The primary breakup of a planar liquid jet is explored via direct numericalsimulation (DNS) of the incompressible Navier-Stokes equation with level-setand volume-of-fluid interface capturing methods. PDFs of the local radius ofcurvature and the local cross-flow displacement of the liquid-gas interface areevaluated over wide ranges of the Reynolds number ($Re$), Weber number ($We$),density ratio and viscosity ratio. The temporal cascade of liquid-structurelength scales and the spread rate of the liquid jet during primary atomizationare analyzed. The formation rate of different surface structures, e.g. lobes,ligaments and droplets, are compared for different flow conditions and areexplained in terms of the vortex dynamics in each atomization domain that weidentified recently. With increasing $We$, the average radius of curvature ofthe surface decreases, the number of small droplets increases, and the cascadeand the surface area growth occur at faster rates. The spray angle is mainlyaffected by $Re$ and density ratio, and is larger at higher $We$, at higherdensity ratios, and also at lower $Re$. The change in the spray spread rateversus $Re$ is attributed to the angle of ligaments stretching from the jetcore, which increases as $Re$ decreases. Gas viscosity has negligible effect onboth the droplet-size distribution and the spray angle. Increasing thewavelength-to-sheet-thickness ratio, however, increases the spray angle and thestructure cascade rate, while decreasing the droplet size. The smallest lengthscale is determined more by surface tension and liquid inertia than by theliquid viscosity, while gas inertia and liquid surface tension are the keyparameters in determining the spray angle.

Background. This experimental study sought to assess the biocompatibility of Resil, an experimental epoxy resin-based sealer, in comparison with AH26 and AH-Plus sealers in rats. Methods. Twelve male Wistar rats weighing 400 to 500 grams were evaluated in this experimental study. Four polyethylene tubes containing Resil, AH-Plus, AH26 sealers, and an empty tube were implanted subcutaneously in rats. The degree of inflammation, type of inflammatory cells present, foreign body reaction, quality of connective tissue, and presence of fibrotic capsule were evaluated histopathologically at 7 and 30 days after implanting the tubes to assess the biocompatibility of sealers. Data were analyzed using the Chi-square test. Results. At 7 days, the degree of inflammation in Resil group was almost similar to AH26 group, and 66.7% of rats showed moderate inflammation. AH-Plus group showed less inflammation than Resil and AH26 (50% of rats showed low degree of inflammation), At 30 days, the inflammatory status of all groups was the same, and 83.3% of rats showed very low degree of inflammation. The inflammatory response during the experiment decreased from day 7 to day 30 in all groups. The neutrophil count (P=0.00), fibrotic capsule (P=0.01) and the amount of granulation tissue (P=0.05) significantly decreased from day 7 to day 30 in Resil group. Conclusion. Resil sealer showed appropriate biocompatibility at 7 and 30 days after subcutaneous implantation in rats, comparable to AH26 and AH-Plus. Clinical studies are required to confirm these results.

The purpose of this applied research is to design the ontology of military history domain of the Iran-Iraq war, in order to represent the sources of this domain. No specialized tools such as thesaurus or ontology have been designed to organize information in the Iran-Iraq war domain. To meet the information needs of researchers in this domain, we need representation of concepts in this domain; And since ontology is currently the most accurate tool available, this tool has been designed in this research. In this study, the content analysis method and domain analysis approach were used to extract the concepts and relationships between them; and Noy and McGuinness (2001) seven-way method were used to design ontology in a manual process. The research community is all written sources in the category of military history of the Iran-Iraq war. Sampling was done purposefully and 18 volumes of books from the category of military history of the Iran-Iraq war, available in the specialized library of the Hozeh Honari, were selected to analyze and extract key concepts and relations. After the initial study and extraction of key concepts and relationships, in order to confirm the accuracy of the extracted items, the opinion of military experts in this domain was applied in the research and the final approval of the experts was received; and Protégé 5.5.0 software was used to formalize these concepts. Finally, the ontology of the military history of the Iran-Iraq war was designed, with 880 axiom, 54 classes, 76 Individuals, 32 object property, 24 data type property, and 2 annotation data type properties. The main classes of this ontology include: military strategy with 11 subclasses, military operations with 11 subclasses, commanders with 5 subclasses, military organization with 17 subclasses, and war support with 5 subclasses. Designed ontology, in addition to representing concepts and semantic relationships in the domain of military history of the Iran-Iraq war, can also be used to improve information retrieval in the process of organizing and Query expansion in storage and retrieval systems. This representation provides an overview of the military history of the Iran-Iraq war to researchers and scholars, and can also be used as a tool for organizing war resources.

BackgroundEating disorders and obesity are serious health problems with poor treatment outcomes and high relapse rates despite well-established treatments. Several studies have suggested that virtual reality technology could enhance the current treatment outcomes and could be used as an adjunctive tool in their treatment. ObjectiveThis study aims to investigate the differences between eating virtual and real-life meals and test the hypothesis that eating a virtual meal can reduce hunger among healthy women. MethodsThe study included 20 healthy women and used a randomized crossover design. The participants were asked to eat 1 introduction meal, 2 real meals, and 2 virtual meals, all containing real or virtual meatballs and potatoes. The real meals were eaten on a plate that had been placed on a scale that communicated with analytical software on a computer. The virtual meals were eaten in a room where participants were seated on a real chair in front of a real table and fitted with the virtual reality equipment. The eating behavior for both the real and virtual meals was filmed. Hunger was measured before and after the meals using questionnaires. ResultsThere was a significant difference in hunger from baseline to after the real meal (mean difference=61.8, P

Abstract Introduction The aim of the present study was to explore and determine the association between BMI and socio-economic factors in Iran. Methods Adults aged 35 to 70 (n = 20,460) were included from Ardabil Non-Communicable Disease (ArNCD) cohort study. BMI was calculated as kg/m2. Principal Component Analysis (PCA) was used to determine the socio-economic quintiles. Multivariate linear regression was performed to analyze the association of BMI as dependent variable with explanatory variables, Additionally, decomposition analyzing conducted to identify factors that explained wealth-related inequality in obesity. Results The prevalence of overweight and obese people was 83.7% (41.4% overweight and 42.5% obese) wherein the highest frequency of obese people belonged to the age group of 45 to 49 years old (19.9%) and to the illiterate people (33.1%). The results of multivariate linear regression model showed that age, being female, marriage, lower education level, having chronic disease, alcohol use, and higher socioeconomic level positively associated with obesity. The results of the decomposition model showed that the most important variables affecting socioeconomic inequality in higher BMI level were socioeconomic status (75.8%), being women (5.6%), education level (− 4.1%), and having chronic disease (2.4%). Conclusion BMI showed significant association with socio-economic status, where richest people had significantly higher BMI than poorest group. Considering the direct role of high BMI in non-communicable diseases, new policies are needed to be developed and implemented by means of diet intervention and increased physical activity to control the BMI in the population of Iran.

Abstract Background Electrocardiogram (ECG) interpretation is a core clinical skill that helps to rapid diagnosis of potentially life-threatening diseases. Misinterpretation of the electrocardiogram can lead to inappropriate clinical decisions with adverse outcomes. The main aim of this survey was to assess the competency of electrocardiogram interpretation and related factors among healthcare professionals and students of Ardabil University of Medical Sciences. Methods This descriptive cross-sectional study included 323 staff and students of Ardabil University of Medical Sciences in northwestern Iran. Data were collected randomly from November to January 1400 using the Badell-Coll ECG Interpretation Competency Questionnaire and analyzed using SPSS V.14. Statistical analysis included descriptive statistics, independent t-test, ANOVA, Pearson correlation coefficient and multiple linear regression. Results The results showed that the mean and standard deviation of electrocardiogram interpretation competency of health professional staff and students was 5.13 ± 2.25 (maximum score = 10). The large number of participants wasn’t able to identify normal sinus rhythm (n = 251, 77.3%), acute myocardial infarction (n = 206, 63.8%) and pathological Q waves (n = 201, 62.2%). The results of multiple linear regression showed that the variables of education level, self-assessment of electrocardiogram interpretation competence, work experience, and type of hospital were able to predict the competence of ECG interpretation in participants. Conclusions Our findings showed that the participants’ level of electrocardiogram interpretation competency was low. Hence, regular, standard training and education are recommended. Also, managers and educators of the health system should consider the role of positive self-assessment and exposure to ECG interpretation in improving the competence of staff and students to interpret ECG.

Purpose: Health-promoting schools have been associated with improvements in the health status of students globally. This study is a secondary analysis study assessing Iranian HPSs. Design/methodology/approach: This was a cross-sectional study on routinely collected data using an external audit 63-item checklist, which was utilized to evaluate 440 HPSs between 2014 and 2017. The mean score for each of the checklists' components was calculated. Nonparametric tests were conducted to investigate the association between the presence of a school caregiver, students' educational level and the school's score. Findings: While the number of five- and four-star schools increased significantly, one- to three-star schools declined. Providing clinical and counseling services had negative growth. Despite the steady growth of the staff's health, this category still had the lowest score among; on the contrary, physical activity had the highest score in 2017. The presence of a full-time school caregiver and middle schools were both significantly correlated with achieving higher scores (p < 0.005). Originality/value: It seems that in addition to developing school facilities to promote physical activities, measures should be taken to promote access to counseling services, considering health issues of students and staff and finally increasing the number of full-time school caregiver.

Objectives The incidence of cardiovascular disease (CVD) mortality is increasing in developing countries. This study aimed to decompose the socioeconomic inequality of CVD in Iran. Methods This cross-sectional population-based study was conducted on 20 519 adults who enrolled in the Ardabil Non-Communicable Disease cohort study. Principal component analysis and multivariable logistic regression were used, respectively, to estimate socioeconomic status and to describe the relationships between CVD prevalence and the explanatory variables. The relative concentration index, concentration curve, and Blinder-Oaxaca decomposition model were used to measure and decompose the socioeconomic inequality. Results The overall age-adjusted prevalence of CVD was 8.4% in northwest Iran. Multivariable logistic regression showed that older adults, overweight or obese adults, and people with hypertension and diabetes were more likely to have CVD. Moreover, people with low economic status were 38% more likely to have CVD than people with high economic status. The prevalence of CVD was mainly concentrated among the poor (concentration index, −0.077: 95% confidence interval, −0.103 to −0.060), and 78.66% of the gap between the poorest and richest groups was attributed to differences in the distribution of the explanatory variables included in the model. Conclusions The most important factors affecting inequality in CVD were old age, chronic illness (hypertension and diabetes), marital status, and socioeconomic status. This study documented stark inequality in the prevalence of CVD, wherein the poor were more affected than the rich. Therefore, it is necessary to implement policies to monitor, screen, and control CVD in poor people living in northwest Iran.

Background: By explaining the reasons for non-compliance with the protocols of the National Anti-coronavirus Headquarters, we can help respond better, make better decisions, and control the risks and outcomes of coronavirus in the future. This study aimed to explain the reasons for the public’s non-compliance with the National Anti-coronavirus Headquarters measures from the perspective of academics. Materials and Methods: The present qualitative study uses a contractual content analysis approach. The study participants were 19 professors and experts of the University of Medical Sciences with the necessary and sufficient information and experience on the subject. A purposive sampling method with maximum diversity in characteristics such as age, gender, education, the field of study, and work experience was used to select the participants. The study data were obtained through semi-structured interviews until data saturation and analyzed simultaneously. Results: From the content analysis of the interviews, 5 main themes and 7 subthemes emerged: 1) normalization and simplification of coronavirus risk with 5 subthemes of learning weakness, inconsistency in received information, misperception of coronavirus, perceived harms due to the observance of protocols, and the impracticality of some policies and approvals of the National Anti-coronavirus Headquarters, 2) weak communication, trust and low acceptance of the people by the procedures of the Anti-coronavirus Headquarters, 3) lack of sufficient motivation in people to comply with, 4) family-cultural conditions with two subthemes of the emotionality of Iranian families and the received cultural sediments, and 5) weakness in supervision and compassion in the use of force. Conclusion: The study results showed that from the point of view of academics, there are reasons for people not observing the recommendations of the National Anti-coronavirus Headquarters, which leads to more ineffective control of coronavirus and consequently human, economic, and social damages to the country. Given the importance of coronavirus control in promoting community health and prevention of this disease and its dangers, further understanding of the reasons for non-compliance with the procedures and recommendations of the National Anti-coronavirus Headquarters to plan and carry out effective interventions seem necessary.

Temporal instabilities of a planar liquid jet are studied using direct numerical simulation (DNS) of the incompressible Navier–Stokes equations with level-set (LS) and volume-of-fluid (VoF) surface tracking methods. $\unicode[STIX]{x1D706}_{2}$ contours are used to relate the vortex dynamics to the surface dynamics at different stages of the jet breakup – namely, lobe formation, lobe perforation, ligament formation, stretching and tearing. Three distinct breakup mechanisms are identified in the primary breakup, which are well categorized on the parameter space of gas Weber number ($We_{g}$) versus liquid Reynolds number ($Re_{l}$). These mechanisms are analysed here from a vortex dynamics perspective. Vortex dynamics explains the hairpin formation, and the interaction between the hairpins and the Kelvin–Helmholtz (KH) roller explains the perforation of the lobes, which is attributed to the streamwise overlapping of two oppositely oriented hairpin vortices on top and bottom of the lobe. The formation of corrugations on the lobe front edge at high $Re_{l}$ is also related to the location and structure of the hairpins with respect to the KH vortex. The lobe perforation and corrugation formation are inhibited at low $Re_{l}$ and low $We_{g}$ due to the high surface tension and viscous forces, which damp the small-scale corrugations and resist hole formation. Streamwise vorticity generation – resulting in three-dimensional instabilities – is mainly caused by vortex stretching and baroclinic torque at high and low density ratios, respectively. Generation of streamwise vortices and their interaction with spanwise vortices produce the liquid structures seen at various flow conditions. Understanding the liquid sheet breakup and the related vortex dynamics are crucial for controlling the droplet-size distribution in primary atomization.

The conflict between form and meaning is not a new phenomenon, especially in the translation of sacred texts . The Quran's fusion of style and content, as well as the unparalleled quality of its structure, have made its translation an arduous task for translators. The aim of this descriptive study was to investigate the adjustments to form and meaning in three translations of Az Zariyat surah (by Arberry, Pickthall, and Shakir). The English and Arabic versions of this surah were contrasted based on the semantic and structural adjustments applied by Nida and Taber in the translation of the Bible. The results revealed that more than three-quarters of the adjustments were concerned with semantic adjustments, with lexical expansions being the most common. Furthermore, structural adjustments and reductions were made to a lesser extent compared to other modifications. Translators mostly chose to stick to the source text, describing only ambiguous or abstract words in the source text and avoiding significant reductions. This behavior can be explained by the sensitivity of the Quranic verses and the translators' willingness to remain faithful to the original text . The adjustment framework introduced in the present study may offer promising avenues for tackling the dilemmas in the way of rendering the style and content of the Quranic verses.
