The applications of reinforced composites and heterogeneous solid materials have been widely developed in different fields of aerospace and mechanical engineering. In this research, the necessity of using non-destructive methods in identifying possible damages in composite materials is pointed out. In addition, the acoustic emission method is described and compared with other non-destructive evaluation methods. It is stated that acoustic emission is a dynamic diagnosis method which can instantly show discontinuities in a structure under tension. The nature of acoustic emission signals is mentioned as an electrical signal. Finally, it is concluded that the best method to check the delamination and fiber damage in composite laminates is the acoustic emission method.

In this paper, we introduce a path hyperoperation associated with a hypergraph,which is an extension of the Corsini’s hyperoperation.We investigate some related properties and study relations betweenthe path hyperoperation and hypergraph theory.

This research aimed to study the effect of virtual social networks on self-care of the users concerning COVID-19.

This survey research was conducted from April to June 2020. The study sample included social network users (WhatsApp, Instagram and Telegram) in Hormozgan province who were selected by convenience sampling. The measuring instrument was an online questionnaire extracted from Dorthea E. Orem’s self-care model, Gerbner's cultivation theory and Kaplan and Haenlein's media-richness-theory. Modeling was carried out using SPSS 28 and Amos 26 software.

The results of explanation and modeling in the present research not only indicate a significant and direct relationship between the independent variables of Presence and interaction in the social networks and user orientation to the type of social network with the dependent variable of users concerning COVID-19 self-care (p<0.0009), but also, 45% of changes in COVID-19 self-care variable was covered by a set of social networking indices. Structural equation modelling in the self-care variable also showed that independent variables; Presence and interaction in the social networks and user orientation to the type of social network had the highest and lowest effects on the psychological support dimension with a standard coefficient of 0.99 and the dimension of awareness and attention to COVID-19 effects and outcomes with a standard coefficient of 0.95, respectively.

As a result, we suggest that health officials and disease control and prevention centers use the potential of social networks such as WhatsApp and Instagram in self-care of users concerning COVID-19.

Ethical decision making in NGOs has a positive impact on the economy, industry and society. This research aims to explain the native model of moral decision-making in NGOs.

The present research method is applied in a quantitative cross-sectional study for the purpose of applied research, in terms of exploratory (qualitative and quantitative) data, and in terms of the nature of the qualitative aspect of the data of the Foundation. The statistical population is the qualitative section of human resource managers and experts who were identified by targeted sampling method. In the small part, 306 employees of Saman were selected by census method. In the qualitative section, data was analyzed by open, axial and selective coding. In the quantitative section, descriptive statistics such as descriptive tables, statistical characteristics, charts and factor analysis were used.

The results indicate that the process of moral decision-making in non-governmental organizations in the underlying circumstances influences interpersonal factors, context, organizational factors, in interventional situations, transactional and religious factors in interactions and actions of individuals.  The results of the confirmatory factor analysis indicated good fit of the model and the veracity of the design of the relationship.

The findings indicated that the dimensions identified for the model of ethical decision making are dimensions such as religious, individual-personality, interpersonal, organizational and transorganization. In the quantitative section, the AGFA, GFI, RMSEA and Khidou indicators also indicate that the dimensions identified support a concept called moral decision.

Soundscape analysis, using acoustic indices, provides researchers with valuable ecological information to assess biodiversity, species behavior, and noise pollution. In this study,  to analyze biophonies and anthrophony in six urban parks in  Isfahan city in spring, six acoustic indices, including Acoustic complexity index (ACI), Acoustic Diversity Index (ADI), Acoustic Evenness Index (AEI), and Bioacoustic Index (BI), Normalized Difference Soundscape Index (NDSI) and Entropy Index (H) were used and quantified using  Seewave Package in R software. In the next step, using ANOVA test, we evaluated the significance of difference between values of the indices among the six parks. We also calculated the degree of correlation between pairs of the indices among and within the parks using Tukey test. According to the results of ANOVA and Tukey tests, the highest values of BI, NDSI, ACI, ADI, AEI and H indices were obtained for Sofeh Park with values of 51.63, 0.99, 2267, 1.46, 0.89 and 0.82, respectively and the lowest values of the these indices were also calculated for Mahmoud-Abad (16.56 and - 0.49), Isargaran (1787) and Bagh-Ghadir (0.05, 0.67 and 0.41) Parks. Among the indices, the most significant difference was calculated for the two indices of ADI and NDSI and between the Sofeh and Mahmoud-Abad Parks, indicating the effect of factors such as edge effect and birds diversity on these indices. Based on the results, it can be concluded that NDSI and BI indices are suitable tools for evaluating ecosystem quality and can be used in green space management and urban biodiversity assessment.

Propose: Generalized anxiety disorder (GAD) is one of the most common psychiatric disorders. So far, no study has examined their respiratory system changes. The purpose of this study was to compare the respiratory pattern indices of healthy individuals and individuals with generalized anxiety disorder.

  In the current cross-sectional study, 16 patients with clinical diagnosis of generalized anxiety disorder (GAD) with referral to a psychiatrist were compared with 16 matched healthy individuals. The information of the respiratory system was collected using a chronograph and spirometery. The Pulmonary function tests recorded were FVC, FEV1, FEV1/FVC end-tidal CO2 pressure and respiratory rate were measured using Capnograph. The Nijmegen questionnaire was used to quantify hyperventilation complaints.

The results of this study showed that anxiety patients had significantly lower levels of FEV1 and FEV1% in comparison with healthy subjects. Exhaled carbon dioxide and respiratory rate were significantly different between the two groups The Niggins questionnaire score was significantly higher in the group of anxiety patients than in the healthy subjects.

Respiratory pattern in people with generalized anxiety disorder was changed by respiratory volume, increased respiratory rate and decreased CO2. The current findings suggest that assessment of respiratory system in GAD patients can be effective in the early diagnosis and treatment process of breathing problems in physiotherapy centers.

Space is the core of how social and cultural events take place. Also, the relationship between activity and space is more comprehensible in the existing relationships between spaces and the relationships between audiences and social interactions than can be defined individually in the characteristics of space. This study tries to get acquainted with the graph theory and the basics of Space Syntex plugin and by explaining its mathematical relations evaluate the architecture of the Qajar period and the relationship between the companionship of spaces in a sample of Isfahan Qajar houses (Jangjouyan House)

The research method of the study is a descriptive-analytical, sci-tech anaysis with a case study strategy, for which the definitions of “Grasshopper” and” Space Syntax” are used to quantify it. The present study introduces the value of control in space, which implies the adaptability of space as one of the indicators of flexibility.

As the most permeable space, the yard has the highest ability to create spatial coherence and the highest level of control over other spaces, and on the other hand, the service spaces have the least amount of flexibility.

The courtyard positioning in the middle layers and its relationship with the intermediate spaces including the corridors, stairs, and partitions create a significant role for it, leading to its flexibility in the spatial configuration, while the location of yards in the primary layers in the contemporary homes has declined in its importance and this role has been transferred to other spaces.

The purpose of this study is to identify and classify the dimensions and components of the employee engagement for indigenous and authentic knowledge in accordance with the Holy Quran guidelines and the translation of Sharif al-Mizan's interpretation.

In this study, using the MAXQDA 11 software, the 20-volume interpretation of al-Mizan in the use of the NOOR Comprehensive Software was reviewed and coded.

In this context, more than 284 primary topics were identified which reduced to 104 after final refinement. Primary themes were grouped into 29 main themes and then organized in the form of 8 organizer themes. The 8 organizer themes were categorized as two general themes of individual and organizational engagement.

From the Qur'an's point of view, engagement refers to the individual aspect and pays particular attention to the nature of man; therefore, paying attention to one's belief system and nurturing it according to human nature leads to the formation of one's inner beliefs and desires in order to reach the Lord's satisfaction and one's happiness and engagement.

Patient’s awareness about their rights in addition to increase the service quality and health care and reduce medical expenses (cost), can cause the medical staff also take responsibility of protection of patients’ rights. Therefore, this investigation was conducted in order to determine awareness from patient right patent and its consideration (observance) from hospitalized patients’ viewpoint.

This cross-sectional study was conducted through available sampling on 384 hospitalized patients referred to Zahedan Medical University hospitals in 1390. Information collecting tolls were including: demographic information check list and two questionnaires regard patients awareness and observance about patient right patent. Data were analyzed by Pearson’s test of correlation, two-sample t-test and one-way ANOVA, and Through SPSS software version 16.0.

Results showed that average score of patients awareness about their rights patent was 6.48 (SD=1.3) (in weak level) and average of observance of right patent from patients viewpoint was 6.28 (SD=1.02) (in adverse level). Also analysis of the seventh realms related to awareness and patient’s right patent observance showed that minimum and maximum average score were related to objection and complaint right (0.15±0.85 and 0.25±0.05) and awareness right and get information (2.1±0.55 and 2.8±0.68), respectively. There was a significant relationship between awareness of patients about their rights and patient’s right patent observance (P<0.05).

According to the obtained results, it is necessary that hospitals managers must adopt some measures to make qualifications in order to awareness of patients about their rights and execution of the laws related to observance of patient’s rights.

In 2012 methyl mercury toxicosis rapidly caused affected cattle enable to move, recumbent and even moribund in this intoxication. Pathological findings were hyalinization and fibrinoid necrosis of the meningeal and brain parenchyma vasculatures, degeneration and necrosis of the nerve cells including the cerebellar purkinji cells,hemorrhages within leptomeninges and Virchow Robin spaces due to vascular damages, brain edema and toxic nephritis characterized by coagulative necrosis and degenerative changes of the cells lining of proximal tubules of the kidney. In this engagement the amount of methyl mercury in the fixed brain tissue, kidney and liver of moribund slaughtered cattle were 0.07, 0.03 and 0.02 ppm respectively. In addition, the amount of methyl mercury of rice straw, the main food of the two affected sections of the herd, was 0.9 ppm. Considering clinical symptoms and histopathological findings in the brain and kidney and toxicological examination, the heavy pregnant cattle and low milk producing cows which consumed much more contaminated rice straw had methyl mercury intoxication. Due to lack of mercury binders, it was not possible to treat the intoxicated animals. Nevertheless, it is necessary to consider the three following advices; -animals should not reach to mercury polluted feed staffs, 2-as soon as new cases diagnosed, they should be treated with charcoal, an astringent and complimentary treatments including liquid therapy and injection of anti-oxidants (Vitamin C, Vitamin E and Selenium).

Background and

Ôstomatitis or oral mucositis is one of the prevalent problems in under chemotherapy patients that resulted in complications such as pain, infection, malaise and Ïncreased length of hospital stay. Ôral hygiene and application of an appropriate mouthwash are only ways for prevention of these problems. The goal of this study is assess the effect of chamomile mouthwash to prevent of ostomatitis in children under chemotherapy.

Ïn this quasi-experimental-double blinded study 52 under chemotherapy childs were randomly assigned in two study and control groups. Patients in study group taught that after chemotherapy, brush their teeth and dilute 30 drops of chamomile mouthwash in 20ml water, then troll it in mouth for 1 minute, and then outpour it and dont eat anything for an hour. This performs three times a day for 14 days. Patients mouth were examined on days 7 and 14 and then their ostomatitis recorded according to WHÔ scale.

Result indicated that incidence of ostomatitis in study group after 7 days was 42.3% and in control group was 76.9% (P≤0.01).Çonclusion: Prevention of ostomatitis in the under chemotherapy children cause better accept ion of treatment in children. Çhamomile can be use as a suitable mouthwash to prevent ostomatitis in under chemotherapy children and resulted in improving nutrition and satisfaction of child and parents.

The prevalence rates of symptoms of asthma, allergic rhinitis and eczema which are common disorders of children vary widely in different areas. The aim of the study was to estimate the prevalence and severity of allergic disorders among Ahvazian children by ISAAC protocol in 2006-7. Subjects and The descriptive study was conducted on primary (6-7 years) and guidance (13-14 years) schoolchildren who were randomly selected among Ahvaz schools by cluster sampling method. Data were collected using phase I standardized International study of asthma and Allergy in child hoos (ISAAC) questionnaire which was completed by schoolchildren itself or by the parent of each child. Data were analyzed by SPSS-15 and using Chi-square test. The prevalence of symptoms of asthma, allergic rhinitis and eczema were 14.1%, 18.2% and 8.4% respectively. Sex difference was not significant, while by educational level guidance students showed significant higher prevalence for asthma and allergies

The interest of using geo-materials as an ordinance barrier has provided the motivation for studying projectile penetration into soil covered concrete targets for many decades. Protection of sensitive concrete structures against projectile penetration is usually accomplished by using soil layers. One of the main problems is how to estimate and determine the thickness of the covered material and at the same time calculate the crater depth of the concrete when subjected to high velocity projectiles.The aim of this paper is to determine the crater depth of an ogive-nose shape steel projectile penetrating into a concrete target covered with soil. To achieve this objective spherical cavity expansion theory is employed and an analytical model for penetration depth is developed. Also, penetration process into soil covered target is simulated using LS- DYNA capabilities. The results of the simulation and analytical formula are compared and a good agreement is recorded.
