background: total and partial gastrectomy is commonly used to treat gastric carcinoma or other benign or malignant conditions of the stomach. laparoscopic-assisted distal gastrectomy is an alternative approach for treating mucosal gastric cancer. many investigators have assessed the safety, efficacy, and feasibility of this procedure.rnobjectives: the aim of present study is to compare the outc...

background: the recent developments in tissue doppler imaging (tdi) now more than ever permit the quantification of the myocardial function. in the current systems, tissue tracking or displacement curves are generated from color tissue doppler data through the instantaneous temporal integral of velocity-time curves. methods: the purpose of the present study was to assess regional myocardial dis...

background and aim: patients who receive hemodialysis need effective education in order to maintain their health. one of the effective methods for education is computer-assisted education. the aim of this study was to compare the impacts of computer-assisted multimedia education and traditional method on clinical parameters of patients receiving hemodialysis. methods: in this interventional stu...

Introduction: Treatment planning is the most important part of treatment. One of the important entries into treatment planning systems is the beam dose distribution data which maybe typically measured or calculated in a long time. This study aimed at shortening the time of dose calculations using artificial neural network (ANN) and finding the best method of training t...

objectives: the purpose of this study was to develop and test a new tool for radiographic densitometry by combining periapical films and aluminum step wedge. materials and methods: we reviewed 50 kodak e-speed intraoral films. an aluminum step wedge consisting of 16 steps was constructed. each step was 1mmx3mx10mm. the step wedge was exposed to varying exposure times, ranging from 0.05 second t...

The participation of users within AAL environments is increasing thanks to the capabilities of the current wearable devices. Furthermore, the significance of considering user's preferences, context conditions and device's capabilities help smart environments to personalize services and resources for them. Being aware of different characteristics of the entities participating in these situations...

The surface reconstruction problem for three-dimensional (3D) scattered point data derived from 3D range scanners has been investigated in fields such as computer graphics (CG) and computer-aided design (CAD) [1, 2]. By using an implicit function-based method, the surface reconstruction problem can be solved. However, it must be noted here that, for generation of an implicit function in general...

INTRODUCTION We have seen a rise in computer misuse at a global level and also the development of new policies and strategies to describe organized computer security attacks against the information society–these strategies are described as being “information warfare.” This is very different from the traditional view of attack against computers by the individual, determined hacker, a cyber warri...

This study aimed to investigate the effect of using vocabulary software on the vocabulary learning of Iranian EFL learners. Participants of the study were 54 intermediate-level students (23 males and 31 females) learning English as a foreign language in Mehr Institute in Izeh who were selected after taking the Nelson English Language Test as a proficiency test. They were randomly divided into t...
