This paper puts emphasis on the necessity of discussing positionality in qualitative research methods, especially ethnography. Evaluating a qualitative study requires the reader to get information about the researcher's positionality with respect to their various social identities (like gender, race, class, ethnicity, ability, geographical location etc and with their intentions for doing the fieldwork, their feelings and emotions, and their relationships with the informants. This paper ties to analyze eight published papers and one book based on qualitative and ethnographic studies in the Iranian society. It examines the harms and consequences of failure in discussing a researcher's positionality by applying a critical ethnographic and reflexive approach. Indeed, the paper analyzes the writers' use of language, their reasoning for doing the research and the reflexive discussion of their positionality while doing the research and later in writing a research report. It argues that not observing the reflective approach in research and concealing the researcher's positionality deprives the reader of the possibility of identifying possible bias. The paper also discusses two other consequences that are more recognizable in academic writing in Iran: "Self-heroism" display of research. Consequently, instead of clarifying their intentions and understanding the field and its relations, researchers solve problems and offer quick solutions.

Admitted neonates in neonatal intensive care units undergo painful, invasive procedures that can have serious consequences. Nurses have a crucial role in pain management. However, studies have shown that their knowledge and attitude in pain management are not acceptable. The present study was done to study the impact of virtual education in pain management on the nurses working in neonatal intensive care units affiliated with Shiraz University of Medical Sciences.

In this quasi-experimental study, 60 nurses completed knowledge and attitude questionnaires on the neonates’ pain management. Then, they were educated through two virtual education sessions through Adobe Connect. The questionnaires were completed again 8 and 30 days after the educational session. The data was analyzed using SPPSS 21 software through the Bonferroni Test.

There was a significant difference between the mean score of knowledge before (17.48±3.14), one week after (19.37±3.63), and the educational intervention (p<0.001). However, the difference between the mean score of knowledge one week and one month after (19.42±3.41) the intervention was not significant (p=0.998). There was no significant difference between the mean attitude score before (52.78±4.62) and one week after the intervention (52.93±4.58; p=0.096). However, this significantly differed after one month (53.45±4.48; p=0.043).

Virtual education increases nurses' knowledge about pain management in one week; however, it changes their attitude in one month.

The birth of a premature neonate and separation from the family due to hospitalization in the neonatal intensive care unit lead to tension in the parents, especially the mother. The aim of the present study was to determine the correlation between general health and self-efficacy of mothers with premature neonates admitted to the hospitals affiliated to Shiraz University of Medical Sciences.

This descriptive-correlational study was performed on 100 mothers whose premature neonates were hospitalized in NICUs of Hafez, Namazi and Hazrat Zeinab hospitals in Shiraz City in 2018.
Data were collected through demographic, self-efficacy and general health questionnaires and analyzed by SPSS 25 software. The correlation between general health and self-efficacy of mothers was measured using Pearson correlation test.

The mean scores of mothers’ self-efficacy and general health were 63.60±13.17 and 28.13±16.96, respectively. 50% of the mothers had no general health problem. 31%, 11% and 8% of the mothers suffered from mild, moderate and sever levels of general health problem. The correlation between the mean scores of general health (r=-0.903) and its subscales with the mean score of mothers' self-efficacy was inverse and significant (p<0.001).

There is an inverse correlation between mothers' self-efficacy and their general health. Therefore, with the increase of physical problems, anxiety, social isolation and depression, their self-efficacy decreases.

Safety behavior improves the level of safety and health of employees, the general public and the environment. The aim of this study was to determine the mediating role of burnout in the relationship between perceived stress, work and family conflict and emotional intelligence with the safety behavior of health and treatment staffs in Mahabad.

The present study was a modeling of structural equations that examined 200 patients of health and treatment staffs in Mahabad city, selected by random sampling method. Safety behavior, perceived stress, work and family conflict, burnout, and emotional intelligence questionnaires were used to collect data. Data analysis was performed using descriptive and inferential statistics (structural equation modeling method) with Smart-PLS3.2.9 and SPSS-25 software and Bootstrap test.

The findings indicated a fitting of structural model of the research and also the negative and significant relationships of perceived stress, work-life conflict and burnout with safety behavior, as well as a positive and significant relationship of emotional intelligence with safety behavior. The results also showed that burnout plays a mediating role in the relationship between perceived stress, emotional intelligence and work-life conflict with the safety behavior of health and treatment staffs.

The present study showed that perceived stress, work-life conflict and emotional intelligence are able to predict the safety behaviors of health and treatment staffs. It seems that the management system of the organization can improve the safety level of its staffs by optimally managing these important factors.

Social competence is one of the determining criteria for establishing interactions. Health-promoting lifestyle components are related to the studentschr('39') academic performance and quality of life. On the other hand, the ability of academic adjustment can increase the efficiency and academic adequacy of students. The present study aimed to survey the relationship between health-promoting lifestyle and social competence with the meditative role of academic adjustment among the students of Mazandaran University of Medical Sciences.

This cross-sectional analytical study was conducted on 320 students of Mazandaran University of Medical Sciences in the 2020-2021 academic year. . Data collection was performed using stratified proportional sampling method. Flener social competence, Walker health promoting-lifestyle, and Baker and Siryk’s academic adjustment questionnaires were used to collect data. To analyze the data, statistical methods of path analysis and correlation coefficients were utilized by SPSS version 16 and LISREL software’s.

The results of path analysis showed a significant relationship between health-promoting lifestyle and academic adjustment (t=4.24, ß=0.34), health-promoting lifestyle and social competence (t=5.60, ß=0.41), as well as academic adjustment and social competence (t=4.38, ß=0.28; P<0.01).

Regarding the role of a health-promoting lifestyle in increasing academic adjustment and social competence, building positive health beliefs and informing individuals about their effects is also of great important.

In this study, AgI-ZnO/chitosan nanocomposite was synthesized and then was coated on 2×40×200 glass plates under UVA irradiation for the removal of toluene from air streams. The AgI-ZnO/chitosan Nanocomposite was characterized using XRD, SEM, FTIR and BET techniques. The analyses showed Zn and Ag were added to the composite structure with weight percentages of 32.02 and 7.31, respectively. The results confirmed that the AgI-ZnO/chitosan nanocomposite was successfully synthetized. According to the results, the photocatalytic process was able to remove 74.6% of toluene at an air flow rate of 1 L/min after 3.3 min. Also, by increasing the passing flow rate from 0.3 to 1.5 L/min through the photocatalytic reactor, the process efficiency for toluene removal increased. The toluene removal efficiency decreased with increasing relative humidity with respect to time. Moreover, increasing relative humidity decreased the photocatalyst capacity for the removal of the target pollutants. The results implied that the initial toluene concentration in the inlet stream played a key role on the photocatalysis of toluene and by further increase in the pollutant concentration higher than 20 ppm, its performance decreased dramatically. Therefore, the proposed process can be used and an effective technique for the removal of toluene from the polluted air stream under UV irradiation and increasing temperature up to 60 °C could increase its performance.

Hydrolysis protein is obtained by breaking the protein into peptides by enzymatic or chemical reactions. In conditions of freezing, compounds with low molecular weight have fatty oxidation and protein degradation, which is associated with bad odor and taste, and affects the qualitative characteristics of the tissue, so if it can be added by adding hydrolysis protein, surimi result will be better at refrigeration and fresh temperatures. This study aimed to investigate the effect of hydrolysis shrimp on chemical, microbial and tissue changes of surimi silver carp (Hypophthalmichthys molitrix).

Silver carp was converted to bone-free meat by a bone-like machine with a diameter of 2 mm. The non-bulging meat was then washed three times with cold water. The volume of water consumed was 4 times the weight of the meat at each time (ratio 4: 1). In the third step, 0.2% sodium chloride was added. In the final dewatering stage, after pressing the meat on the hand of the fish, a heavy weighing pad was placed on the meat grinder for 10 to 15 minutes to completely remove the water. To prepare hydrolysis shrimp, 250 grams of honeydew taken from Hanijan, peeled and boiled, were hydrolyzed by the alkaline enzyme. Hydrolyzed shrimp was added to surimi at 0.5, 1 and 2% control levels. To carry out this research, for 15 days, refrigerated temperature was measured by measuring microbial load (TVC), biochemical parameters, and texture and color measurements.

The results showed that the hydrolysis protein had inhibitory effects on microbial growth, and in none days, the amount of microbial load did not exceed the permitted limit (107 Log cfu / g) and the microbial load on day zero compared with day 15, in Treatments were significantly increased, but this increase was lower in hydrolyzed protein treatments, especially at 2% level compared to lower levels and control. pH increasing trend during all treatments. Frequency of free fatty acids (FFA) showed a significant difference between different treatments (P <0.05). The highest value of this parameter was observed with respect to day zero to day 15 and in control treatment (4.25 ± 0.03%). In all treatments, peroxide levels did not exceed the permitted level (20-10 mg / kg). In control treatments, and 0.5% of volatile fatty acids increased from (0.4 ± 0.004) to (4.25 ± 0.03%) at the end of the period, while in other treatments this increase was slower. The lowest TBA was measured in 2% treatment. The highest value of this parameter was measured from day zero to day 15 and in control treatment (4.44 ± 0.54 mg malondialdehyde in kilograms). The amount of volatile nitrogen (TVN) showed a significant difference between treatments (P <0.05). The lowest value of this parameter was zero in day 0 and the highest value of this parameter was significant with respect to day zero, to day 15 and control (63.85 ± 1.5 mg/ 100 g sample). Protein hydrolysis also affected surimi's tissue properties. In the results of the color analysis, the brightness parameters (L) and redness (b) decreased and the jaundice parameter (a) increased.

Based on the results, 2% treatment of hydrolysis shrimp could retain surimi's silver carp for up to 12 days.

Evaluation in higher education has been the focus of curriculum development in recent decades to improve the quality of curricula. Comparing existing programs with similar programs at the world's top universities with a comparative approach is one of the methods used in evaluating programs. The purpose of this study was to compare the Master of Nursing Management curriculum in Iran with UC Davis University of California.

This descriptive-comparative study was carried out in 2018, data were collected by searching the internet with the key words of nursing, nursing education, curriculum, California UC Davis and Iran, and using Bereday’s four-stage model: description, interpretation, juxta position and comparison were analyzed.

Both programs showed similar approaches to theoretical and clinical teaching, except that peer learning, distance learning, and preceptorship were found at Yves Davis University. The job duties mentioned for graduates in the MA and US Davis Master's Degree Programs also indicate that the "Management- Leadership" tasks are similar in both programs, but given the educational content, the Iranian program was more practical and its main focus is management, leadership, and policymaking in clinical settings. While at UC Davis University, nurses are prepared for leadership roles in the care system and faculty at colleges and specialist nurses in community.

Iranian universities have paid more attention to the practical and clinical aspects of MSc in Nursing Management and its main purpose is to train the Executive Specialists. It seems that incorporating training units into the course content, considering the clinical nature of the curriculum, is effective in enhancing students' ability

Tay–Sachs is a rare autosomal recessive and neurological disease caused by the accumulation of glycosphingolipid within cell lysosomes. Ganglioside accumulation is caused by a mutation in the beta-hexosaminidase (HEXA) gene and this mutation is reduced by HEXA. The study was to determine and report two cases of TS in a family confirmed by measuring the activity of beta hexosaminidase-A.

The first case was a 3-year-old girl whose developmental growth was approximately normal until she was 9 months old, after which she developed recurrence and had symptoms of swallowing problems, abnormal eye movements, distraction, irritability and growth retardation. On examination of the patient's eye, bilateral reddish-gray spots were observed. In the evaluation of the patient's blood sample, a defect in the activity of beta hexosaminidase-A was reported and accordingly the diagnosis of Tay–Sachs was confirmed, hence the child died at the age of three. The second case was a 1-year-old boy whose development was normal until 6 months of age, after which his development and growth delayed and had apparent symptoms including distraction, irritability, respiratory problems, muscle weakness and lack of limb control, constipation, deafness, mental retardation and finally regression evolved. On examination of the patient's eye, bilateral reddish-gray stains were observed. In evaluation of blood samples, deficiency in the activity of beta-hexosaminidase-A was reported and accordingly the diagnosis of Tay–Sachs was confirmed.

 In children with developmental disabilities, who may develop symptoms of progressive weakness, loss of motor skills, increased motor responsiveness, irritability, blindness and hearing loss, seizures and persistent red cherry spots in the eye after a period of time. the diagnosis of Tay–Sachs should be considered.

This study purpose was to determine the mediating role of academic motivations component in the relationship between perceived social support and educational justice with students’ academic burnout.

Method was correlational and statistic population included all students of Islamic Azad University Tehran center and Tehran east branches and Islamic Azad University, Tehran Medical Branch in 2016-2017 first semester with the quantity of 83834 people which through them in a multi-stage random sampling method, in the first stage, 3 universities, from each university 3 colleges and 3 class from each of college, were randomly selected, and finally from departments of Accounting, Psychology, Microbiology, Social Sciences, and genetic engineering, 410 people were selected based on Guadagnoli & Velicer's offer (1998) and the number of parameters. The study tool included Academic Burnout Questionnaire by Berso 1997; Academic Motivation Scale by Vallerand, Pelletier, Blais, Briere, Senecal, et al. (1992); Educational Justice Questionnaire by Golparvar (2010); and Multidimensional Scale of Perceived Social Support by Zimet, Dahlen, Zimet, & Farley (1998). After removal of 40 distortion questionnaires and four outliers, the data were analyzed by structural equation modeling.

The result showed that the indirect path between educational justice with academic burnout (β= -0.121, P= 0.002) and perceived social support with academic burnout (β= -0.253, P= 0.001) is negative and significant.

It is imperative that all students have enough facilities and support in the educational environment to provide their potential for the growth and prosperity of talent to find the motive for their efforts in order to achieve their goals.

Cervical carcinoma is the second most common cancer among women worldwide. In the Middle East it is the most common malignancy in women. Prognostic utility of squamous cell carcinoma antigen (SCCAg) for cervical cancer, and its correlation with pathologic grading has been demonstrated in several studies. However, no such study has been performed in Iran. The aim of the present study was to investigate the frequency of SCCAg and its correlation with histological stage and grade of tumor in blood samples from cervical cancer patients.

Patients referred to the oncology center of Qhaem hospital in Mashad, during a three-year period, from 1382-1385, were included in the study. Previously untreated patients, and subjects in whom no other parts of body were involved with squamous cell carcinomas, were selected. Pretreatment serum SCCAg levels were measured by RIA.

52 patients qualified for the study. The average age of patients was 52.9 years. The most common presenting sign was bleeding (94.1%). 35 patients (64.8%) were in stage II 26 patients (48%) had grade 1 tumor. 29 patients (55.7%) had positive levels for SCCAg with the average of 15.37 ng/ml and median of 10 ng/ml. According to primary evaluations, there was a significant difference in the level of serum SCCAg with size, stage, grade of tumor and lymph node metastases.

SCCAg was positive in a high percentage of patients with cervical squamos cell carcinoma. It may be regarded as a tumor marker in this cancer.

Hydatidosis is a parasitic infection mostly in found in the liver and lung due to echinococus species. But occurrence in other locations is possible. Purpose of this report is to describe a case of bilateral Hydatid cyst in ovaries. Clinical findings with this uncommon location are poorly specific and diagnosis required histologic examination after surgical removal. Imaging and serology is useful to differentiate Hydatid cyst from benign and malignant tumors. This obligatory to examine lung and liver as the main sites of cyst when you are being faced with unusual location of Hydatid cyst especially in endemic area such as Iran. Our patients was a 35 years old woman with history of 4-month abdominal pain in left and right lower quadran. Sonography showed two cysts in adenexal lesions after surgical removal, they were sent to pathology lab. Hydatic cyst membrane was seen in histologic examination of two cystic masses.
