Assessment of Social Distance between Customers in Urban Hypermarket during COVID-19 Pandemic by Simulation Approach

Introduction: Social distance is important for reducing the spread of the new COVID-19 pandemic, especially in public places. In addition, urban stores are one of the crowded places where observing social distance is considered necessary. Therefore, the present study aimed to evaluate the social distance between customers in urban stores during the outbreak of the COVID-19 pandemic using a simulation method. Materials and methods: Research data were collected from the closed-circuit television footage of a store from a hypermarket in Iran, and then customers’ social distance was analyzed through their movement behaviors by two modes of 1 and 2-meter distance using software similar to the Pathfinder simulator. Further parts of the urban store required corrections considering the first scenario and the two-meter distance between people compared to the second scenario and the one-meter distance between them. Results: Based on simulation results, dense areas were identified in different sections of the hypermarket, namely, places where the shelves distance was 1 meter to 2 meters. More precisely, this research provided a method for evaluating different parts of the store in terms of population density regarding maintaining social distance. Conclusion: several suggestions were presented to stores for maintaining social distance based on research findings

Analysis of correlation between estradiol and fracture of femur neck

Osteoporosis is a major public health challenge all over the world. Estrogen hormone was cited amongst other hormones to be an efficient hormone for the production and maintenance of bone density. This study was designed with the purpose of evaluating and analyzing the estradiol effect on fractures of femur neck in the Iranian society. This study evaluated men over 50 years of age suffering with mild trauma (falling off the same level height or lower) and with a fracture on their femur neck. Also, their serum level of estradiol was measured with an ELISA method. Using this procedure, the patients were assigned into groups with either normal estradiol serum level (10pg/ml and higher) or with lower than normal level (lower than 10 pg/ml). A control group including 50-year-old and older men without hip fracture, or its history, was chosen to access their estradiol serum level. Data collected from these two groups were statistically compared. A total of 120 patients were evaluated (60 in the control and 60 in the test group). The mean age of patients in the control and test groups were 67.9±10.22 and 69.5±8.84 years, respectively (p=0.376). Smoker patients’ percentages in the control and test groups were 35% and 31.7%, respectively (p=0.699). On the basis of the serum estradiol level, patients’ percentages with low estradiol level in control and test groups were 10% and 16.7%, respectively (p=0.283). The only significant factor in predicting serum estradiol level was smoking. In conclusion, in this study it was observed that fractures of the femoral neck following a mild trauma were not correlated to low level of serum estradiol

Evaluation of sensitivity and the specificity of Canadian CT head rule and New Orleans criteria in patients with head injury

BackgroundMillions of people around the world are annually under emergency investigation due to severe head injuries. Computed tomography (CT) scans is a diagnostic procedure that can be done for most people. AimsThis study is aimed to evaluate the sensitivity and the specificity of Canadian and New Orleans criteria in determining the rate of head injury.Methods To obtain the relationship between clinical symptoms and CT scan results, the required information was obtained by filling out the records and physical examination in the emergency department and the results from the patients were statistically analysed. Data needed to complete the questionnaire was collected from patient, the patient, their concomitant examination, and the information in their medical records. The raw data from the questionnaire was analysed using SPSS version 17 software. In this study, after obtaining the CT scan results, the individuals were classified into two clinical criteria, New Orleans and Canadian, and their sensitivity and specificity were analysed using ROC curve analysis.Results ROC curve analysis data showed that the sensitivity and specificity of New Orleans criteria are 31 per cent and 69 per cent, respectively, and the sensitivity and specificity of Canadian criteria are 76 per cent and 74 per cent, respectively. Data shows that the Canadian curve has a significant difference compared to basic state (P-Value < 0.05).ConclusionDespite abnormal CT scan results in patients with head trauma, there is a significant relationship between headache and a combination of symptoms in patients. The results can be used in decision-making on involved in performing a CT scan. ROC curve analysis also showed that the Canadian criterion has higher sensitivity and specificity for the diagnosis of severe head trauma compared to New Orleans criteria

The Relationship between Clinical Findings of Shoulder Joint with Bone Damage of Shoulder Joint in Patients with Isolated Shoulder Blunt Trauma

BACKGROUND: Due to the prevalence of shoulder injuries among athletes and other people and the prevalence of radiography for these injuries, there are still no valid criteria for indication of doing shoulder radiography. AIM: This study aimed to examine the relationship between some signs and clinical examinations of the shoulder with shoulder bone injuries and the need for radiography. METHODS: This is a cross-sectional study. All patients aged 18-70 years who referred to the emergency ward of Imam Reza and Hasheminejad Hospital in the year 2014 due to blunt trauma and had criteria for entering the study and lacking exclusion criteria were included in the study process. Data on clinical symptoms, radiographic results, and final diagnosis were extracted from the patients' records through a questionnaire and analysed statistically. RESULTS: There was a significant relationship between the clinical signs of patients Existence of ecchymosis in the shoulder fractures with glenoid and humerus fractures (p = 0.029, p = 0.004 respectively). There was also a significant relationship between clavicle fracture and limitation in shoulder rotation and abduction (p = 0.000 and p = 0.001 respectively). Other clinical symptoms did not show any significant relationship with radiographs indicative of the problem requiring specific treatment. CONCLUSION: Although it is possible to define critters based on clinical symptoms that reduce the need for unnecessary radiographs that the does not reliably help inpatient treatment, but finding these critters to indicate the performance of the graphs in shoulder injuries requires further studies with the higher population and more clinical variables

A Survey on Applying the Golden ratio in Product Packaging and its Effect on Consumers’ buying behavior

Packaging is one of the most effective marketing instruments in selling most of the products, in particular the consuming products. Due to the fact that most purchases particularly in department and chain stores are performed randomly and without a previous programming, packaging has a key role in attracting buyers and their selling products. A package with a charming and elegant design can be very effective in attracting the customers' attention. Different factors like color, shape, structure and such as these are important in packaging attractiveness. Another affective factor of packaging attractiveness is its design with the golden ratio. The golden ratio (1.618) is obtained by dividing the rectangle's length to its width. This ratio is found abundantly in nature and some historical buildings. The present study aims to investigate the effect of golden ratio on the packaging attractiveness and buyers' attraction. To reach this aim, some packages were modeled using golden ratio and a linear planning and were placed besides the packages without golden ratio. Then 400 individuals of Tehran consumers' views were collected. Findings showed that the package designed using golden ratio seems to be attractive. Meanwhile, the results showed that gender and age don't have any effect on the selection of packaging with golden ratio
