No full textDepressive and Anxiety Symptoms in Women with Threatened Abortion: A Case-Control Study
No full textBackground: Threatened abortion (TA) is associated with adverse pregnancy outcomes. Despite the attention paidto the adverse outcomes of obstetrics, only a few studies have been conducted on the psychological status of womenwith threatened abortion. This study aimed to compare the symptoms of depression and anxiety in women with TAand those without threatened abortion.Materials and Methods: In a case-control study, 136 women with TA (the case group) and 136 women without TA(the control group), were matched with the case group in terms of gestational age, education level, age, and numberof pregnancies, were examined from Obstetric clinics of Babol University of Medical Sciences. Demographic informationand pregnancy history were obtained from all participants. Additionally, the women filled out the BSI-18questionnaire. Statistical analysis was performed using SPSS version 22 software.Results: The results showed that in women with threatened abortion, the likelihood of experiencing depressionsymptoms was 1.9 times higher [odds ratio (OR)=1.91, 95% confidence interval (CI)=1.13-3.23, P=0.015], anxietysymptoms were 1.8 times higher (OR=1.83, 95% CI=1.08-3.10, P=0.024), and somatization was 2.6 times higher(OR=2.65, 95% CI=1.61-4.37, P<0.001) compared to pregnant women without threatened abortion. Additionally, inwomen with threatened abortion, the risk of psychological distress was 3.3 times higher (OR=3.30, 95% CI=1.96-5.56, P<0.001) than in women without threatened abortion.Conclusion: This study suggests that gynecologists, midwives, and healthcare providers, in addition to providingmedical care for women threatened with abortion, should identify women at risk of experiencing symptoms of depressionand anxiety. Providing appropriate psychological support should be prioritized in the management of women withthreatened abortion
Wearing your destination: Making tourism experience accessible for people with travel hesitation by using smart glasses
No full textAbstract
This quantitative study is probably one of the primary efforts for offering a potential solution for people with short- and long-term travel hesitation through the lense of Self-Efficacy and Learned Helplessness Theories as well as Technology Acceptance Model (TAM). In this study, travel hesitation is divided to two segments of permanent and temporary. Permanent travel hesitation includes age restrictions, visual, hearing, body impairment, Autism, and any types of disabilities. Furthermore, temporary travel hesitation includes traveling cost, having a new-born, having any types of phobias, being afraid of COVID-19 or any other COVID variants, and having no desires and interest for travel.
The purpose of this study is to offer a solution for people with travel hesitations, and it includes three research questions. The data were collected from 344 sample size through Amazon Mechanical Turk (MTurk) in December 2021. The collected data were analysed through SmartPlS 3.0 software using PLS algorithm and bootstrapping techniques. This research findings verified that people with travel hesitation had willingness to use smart glasses for their travel purposes and also people’s intention to travel physically to a destination after trying smart glasses was increased.Embargo status: Restricted until 09/2027.

Prevalence and Factors related of psychiatric symptoms in low risk pregnancy
No full textBackground: Psychiatric disorders are associated with poor pregnancy outcomes both for mother and child. This study aimed to determine the prevalence and related demographic risk factors of psychiatric symptoms among the pregnant women in Babol City. Methods: This cross-sectional study was conducted in five private and public obstetrics clinics of Babol city. During routine appointments of prenatal care, 176 pregnant women filled in three questionnaires including; sociodemographic questionnaire, Edinburg Prenatal Depression Scale (EPDS), and Symptom Checklist-25 (SCL-25). Wilcoxon test, Spearman correlation, and multivariate logistic regression tests were used to interpret the data. Results: The prevalence of depressive disorders was 15.4 for Edinburg scores ≥13.  The overall rate of maternal psychiatric symptoms (global severity index or GSI scores ≥ 1.75) was 48.5. The prevalence of psychiatric symptoms was high; for 25 somatization, 258 anxiety, obsession-compulsion disorders or OCD 6.4, 8.8 interpersonal sensitivity, 5.3 phobia, 7.6 paranoid ideation, and 1.2 psychoticism. Multivariate logistic regression revealed that pregnant women with history of abortion in previous pregnancy were at risk of depressive symptoms more (β=3.18, CI 1.28-7.93, p=0.01) than those without history of abortion. Also, the only demographic factor related to psychiatric symptoms was the age of pregnant women; younger age was associated with higher symptom levels for GSI ((r=-0.17). Conclusion: The high prevalence of psychiatric symptoms, especially depressive symptoms, in pregnant women highlights the need for continued research on screening, identifying the risk factors, and developing effective treatments for mental disorders in pregnant women
A Critique and study of a narrative of the Fatimids of Egypt and the Ismaili based on the story of Bustan-e-Khayal (Based on historical sources)
No full textStories and tales as an important part of popular culture are the connection between people now and the past that transmits cultural and doctrinal principles from one generation to another. Based on the approaches of modern historiography and the narrative context of historical narratives, some stories also contain historical contexts that are useful to study alongside historical sources. The myth of Bustan-e-Khayal is a folk tale based on the history of the Fatimid caliphs of Egypt and the Ismaili Shiites, which begins based on historical events that took place during. The author has brought these historical figures into the realm of myth, attributing imaginary stories to them. This article follows the presence of the Ismaili religion and the Fatimid caliphs in this story and critiques it based on historical sources and narratives in a descriptive-analytical manner. The findings of this study and their critique indicate the empirical confirmation of some of the author's narrations Based on the historical and doctrinal sources of this political and religious sect, but in some cases, there were differences. The extraordinary face that the author presents of some of the Fatimid caliphs was very close to the aspect of the sanctity and divinity of these caliphs, which has been confirmed by the testimony of historical narrator
Effects of vegetation density, arrangement, and morphology on flow structure under ice-covered condition
No full textAquatic vegetation appears very often in rivers and floodplains, which significantly affects the flow structure. On the other hand, a common feature of cold regions is the presence of river ice on water surfaces. Ice cover imposes an additional boundary layer on water surface which leads to significant change in flow structure and bed deformation. It also causes a decreasing trend of velocity profile near the cover. Because of vegetation’s positive impacts on water quality, habitat, and channel stability, researchers now advocate replanting and restoring projects in rivers, especially in agricultural waterways, floodways, and emergency spillways. The expansion of vegetation in fluvial systems may worsen the flood impact since highly dense vegetation in a channel reduces its flow capacity due to the increase in flow resistance and decrease in the channel width. Therefore, an accurate and critical assessment of the vegetation density and distribution pattern through reduction of bulk velocity is crucial in sustainable restoration projects. To the author's knowledge, no studies have been conducted to investigate the impacts of both ice cover and vegetation on flow resistance and channel bed deformation. It is thus necessary to examine the connection between vegetation and ice covers thoroughly in order to guarantee successful restoration projects. Most of research projects on submerged vegetation have been done in small-scale laboratory flume and specifically under the open channel flow condition. Besides, most of reported research uses uniform sediment which is not an appropriate representative of natural river systems. In the present study, deflected and non-bending model vegetation elements arranged in both square and staggered configurations with different density in the channel bed with three different non-uniform sands under different cover conditions of water surface including open channel flow and ice-covered flow conditions were used. In order to simulate the ice cover condition, smooth and rough ice covers made of Styrofoam panels were created to investigate the impacts of ice cover roughness on channel bed deformation. To represent non-uniform sediment condition, three different bed materials with median particle size (D50) of 0.50 mm, 0.60 mm, 0.98 mm were used. Results showed that the most significant variable influencing the depth of scour holes under ice-covered flow conditions is the ratio of the ice cover roughness to the bed roughness and in open channel flow conditions, the flow Froude number is determining. In the conducted experiments, it was consistently observed that the maximum scour depths occurred at the upstream, front face of the vegetation elements. It was found that the scour holes were deeper and longer under ice-covered flow. In the presence of vegetation in the bed under ice-covered flow conditions, the velocity profiles exhibit a distinct pattern characterized by two peak
values. The study revealed an inverse relationship between canopy density and the dimensions of the wake zone. As the spacing distance between deflected vegetation elements decreases, the streamwise velocity experiences significant retardation slightly below the inflection point. With a sparser vegetation canopy, the inflectional region tends to diminish or disappear. Furthermore, the study observed that the inflection point was not observed in non-bending vegetation. Additionally, velocity profiles showed more pronounced inflection points in the case of a staggered arrangement of vegetation elements compared to a square arrangement. Results of this study will provide vital information for river management, channel restoration, and rehabilitation of fluvial environments through understanding the effect of various vegetation densities, arrangement patterns and morphology, as well as the revitalization of cold-weather river ecosystems

A Psychosocial Risk Assessment Tool to Predict Postnatal Depression in Women with Complicated Pregnancy
No full textIntroduction: Few studies have reported the role of psychosocial risk factors by a validated scale in predicting mental disorders in women with a complicated pregnancy. This study investigated the role of a psychosocial risk assessment tool in the prediction of postnatal depression in women with a complicated pregnancy. Methods: A prospective study was performed on pregnant women with complicated pregnancies from December, 2019, to June, 2020. A total of 125 pregnant women filled the Antenatal Risk Questionnaire (ANRQ), Edinburgh Postnatal Depression Scale (EPDS), and Brief Symptom Inventory 53 items (BSI-53). Also, the patients completed EPDS for 6 weeks postpartum. An expert mental specialist conducted the interviews based on the DSM-5. Results: More than half of the women with complicated pregnancies were diagnosed to have at least one mental disorder. The mean risk scores of ANRQ, including the childhood social support from the respondent’s mother, history of mental illness, perceived level of support available postpartum, significant life events in the past 12 months, and personality traits with high anxiety, were higher in women with mental disorders than those without mental disorders. The results emphasized that the total score of ANRQ was the strongest positive predictor for postnatal depression score of EPDS (β = 0.569, p=<0.001), total score of BSI-53 (β = 0.666 p=<0.001), and GSI (β = 0.237, p=0.019). Conclusion: The study proposes that the use of a validated psychosocial risk assessment tool alongside a psychological screening tool, like EPDS, is reliable for the prediction of mental disorders and help women with complicated pregnancy at risk for the prevention of depression at antenatal visits
Architectural Photovoltaic Applications: Lessons Learnt and Perceptions from Architects
No full textResearchers have reported that despite technological development in photovoltaic technology and substantial cost reduction, there is still a narrow interest in architectural photovoltaic applications (APA). Lack of interest is correlated to various bottlenecks, and one of them is a lack of knowledge among architects on the possibilities and approaches to adopt APA. In response to the issues mentioned, the aim of the research presented was collecting qualitative and quantitative information from architects as lessons learned and perceptions in regards to APA. In total, 30 architects with and without experience of using photovoltaics (PV) were invited and interviewed. They were asked about their experience, design and decision-making process with PV, their understanding of integration, and the decisive factors to use APA. The results showed apparent differences between the experiences and perceptions, and they highlighted the lessons learned from realized projects. The analysis of the visual implication of PV integration shows that, to the eyes of architects, integration of PV into architecture does not depend on the PV product used, but instead, that when PV is part of the design concept and design process, the outcome is seen as a meaningful integration.Climate Design and SustainabilityBuilding Product Innovatio
Psychometric Characteristics of the Wish to Be Dead Scale (WDS) in Iranian Psychiatric Outpatients
No full textThe Wish to be Dead Scale (WDS) was administered to a convenience sample of 200 Iranian psychiatric outpatients. Using a Principal Component Analysis, two factors were identified, labeled Lack of purpose in life (F1), and Lack of interest in living (F2). The WDS had good reliability and significant positive correlations with scores on the Beck Suicide Ideation Scale and with other measures of mental ill-health. This study provides evidence of the usefulness of the WDS for assessing psychiatric patients. © 2016 The Author(s
