One of the major problems in poplar cultivation is the existence of low-yielding poplar species and their traditional cultivation, which reduce wood production per unit area. To identify the most productive and adaptable clones to local climate and introduce them for mass wood production, ten clones of open-crown poplar based on the Randomized Complete Block Design (RCBD) with three replicates and planting spacing (4m × 4m), were selected and evaluated in Khorramabad Agricultural Garden Station for five years (2012-2015). Analysis of variance showed that the year and clone factors had a significant effect on height, diameter and volume increment. The mean comparisons showed that the highest (1.56 m) and lowest (0.77 m) of height increment belonged to Populus euramericana455 clone and Populus x interamericanes clone respectively. Also, the Populus euramericana455 clone had the maximum diameter increment (9.95cm) and Populus x interamericanes clone had the minimum (6/95) diameter increment. The Populus euramericana455 and Populus x interamericanes clones had the highest (8.85 cm) and lowest (1.16 cm) of volume increment in the fifth year respectively. In terms of pest resistance and wood production, Populus deltoides 63/10, Populus deltoids and Populus x costanzo had a better conditions.

Physical activity is one of the most important components of life. The aim of this study was to evaluate the physical activity level of primary school students in Bushehr in 1398. 

In this cross-sectional descriptive-analytical study, the research population included all elementary school students in Bushehr. Four hundred and six students were selected using multi-stage random sampling. The Physical Activity Questionnaire for Children, which is a valid and reliable scale, was used to collect the data. Independent t test, one-way analysis of variance, Pearson correlation coefficient and multiple linear regression model were used for data analysis. Data was analyzed using the SPSS software version 20. 

The mean score of physical activity was 3.27±0.84. There was a significant relationship between demographic factors (parents’ education level, participant’s education level and BMI) and physical activity. Students whose parents had higher levels of education were more likely to engage in physical activity and people who were obese had less physical activity. 

The studentschr('39') physical activity was moderate. Given that there is a direct link between physical inactivity and increased prevalence of overweight and obesity, it is important to pay attention to the lifestyle of people, especially children and adolescents who are in the learning age. Therefore, more attention should be paid to improving the level of physical activity in students through education and building a culture.

Accurate and timely determination of body temperature as one of the vital signs of the body is the key to diagnosis and treatment. Temporal artery thermometer is one of the new tools for measuring body temperature that is still unknown regarding for its accuracy and reliability. Therefore, this study aimed at comparing the specificity and sensitivity of two methods of body temperature measurement by electric subroutine thermometer and digital temporal artery in comparison with nasopharyngeal thermometer in adult patients.

This descriptive-analytical and cross-sectional study was performed on 200 adult patients over 17 years old admitted to the ICU of Shohadaye Khalije Fars Hospital, Bushehr, Iran in 2015. The samples were selected by convenience sampling method. For all samples, body temperature was measured and recorded using three methods, including nasopharyngeal (gold standard), axillary, and temporal arterial methods. Data were analyzed by SPSS 20 and STATA 11 software using Pearson correlation coefficient, chi-square test and ROC curve.

The sensitivity, specificity, and accuracy of the temporal artery method with fever threshold of 37.7°C were 94.0%, 85.0% and 86.5%, respectively, and showed a good agreement between the axillary and temporal artery methods with a kappa coefficient of 0.67.

Body temperature measurement by temporal artery method is precise, fast, comfortable and safe for patients in comparison with nasopharyngeal and axillary methods and the best threshold for fever in this method is 37.7°C.

  Communication skills are the foundation of clinical capabilities in healthcare providers. The process of delivering bad news is one of the most challenging aspects of clinical communication in health care, which has subtle psychological details. The present study aimed to assess the knowledge of nursing students regarding the conveying of bad news to patients and their companions in the hospitals affiliated to Bushehr University of Medical Sciences, Iran. This cross-sectional, descriptive-analytical study was conducted in 2017 in order to assess the knowledge of nursing students at Bushehr University of Medical Sciences regarding the delivery of bad news to patients and their companions. Data were collected using a valid and reliable researcher-made questionnaire. Data analysis was performed in SPSS version 18 using descriptive and analytical statistics. The nursing students had moderate to high knowledge of delivering bad news to patients. In addition, significant associations were observed between the knowledge level, passing the courses of nursing ethics and professional communication (P=0.011), and academic year of education (P=0.037), so that the students who had passed the courses and were in inferior academic years had higher knowledge levels in this regard. However, no significant correlation was observed between the knowledge level, gender (P=0.550), and interest in the academic discipline (P=0.546). Adequate knowledge of professional ethics and effective communication is an advantage for healthcare providers. Based on the obtained results, presenting additional courses on professional ethics and communication skills in nursing education, as well as related training programs, by medical education authorities could lead to better outcomes in this regard.
