The Prevalence of Substance Abuse in Students of Hamadan University
Nahid Mohamadi,Fatemeh Shobeiri,Hossein Mahgoob
Zahedan Journal of Research in Medical Sciences , 2012,
Abstract: Background: Substance abuse refers to a maladaptive pattern of use of a substance. The purpose of this study was to determine the prevalence of substance abuse in hostel boys in Hamadan medical university, 2008. Materials and Method: This research was a descriptive cross-sectional study. The method of sample was census report study and sample number was 430. The research objective data was gathered thorough questionnaire. Data processing and statistical analysis were performed using SPSS software, version 15.0.Results: Outcome showed that the majority of samples were 20 years old (21.9%), non married (92.8%), the number of family member were six members (21.9%), and they are the first children (85.4%).Also outcome showed that 27% of students did not consume any drug, and majority of light material drug abuse was narcotic (44.77%), cigarette (28.4%), alcohol (20.19%) and heavy material was opium (5.25%), hashish (4.1%), ecstasy (1.64%) and others (1.13%). Narcotic was in the first rank and cigarette was in the last. Conclusion: The screening of drug abuse and promoting primary prevention programs at the university were recommended

Pajouhan Scientific Journal , 2013,
Abstract: Introduction: The professional ethics in the medical field is an important concept. Understanding of EMS with professional ethic provide better services and to minimum professional stress. The group discussion method in the teaching of professional ethics is efficiency. The authors benefited of the method to evaluate the awareness of the ethical issues based on training classes.Material and Methods: The study was Cross - sectional. The study population included all of the students of EMS in the final year. Number of samples was 30 and method of sampling was the census method. After of expression course plan pre test was taken and after the end of class final examination was taken. Rate of knowledge of student was assessed after 3 semesters and data obtained were analyzed by software SPSS 16.Results: Rate of knowledge of students before teaching were 97% weak and 3% moderate. The scores of Students was between 20-14 and the mean of was 16.58. Results after 3 terms were this: The average student score 24/69, most samples (80%) have a high awareness and 20% had poor knowledge.Conclusion: The ministry of health policy is edification prior knowledge. The students' awareness of duty was high (80%), in the legal field was very weak and in some areas, such as respect, altruism was moderate.
Throughput Maximizing Frequency and Power Scheduling for Wireless Ad-Hoc Networks in the Low-SINR Regime  [PDF]
Nahid Saberi
Wireless Engineering and Technology (WET) , 2012, DOI: 10.4236/wet.2012.33017
Abstract: We study the problem of frequency and power allocation and scheduling at a time-slotted cognitive ad-hoc wireless network, where cognitive nodes share a number of frequency bands and frequency reuse is allowed. In such a network the throughput maximization problem generally results in a mixed zero-one nonlinear non-convex problem. Interestingly, in the low-SINR regime, the power allocation policy that maximizes the total throughput follows an “on/off” strategy with maximum power usage in the “on” state. In this paper we show that the on/off strategy in the low-SINR regime is also optimal with respect to throughput when scheduling users over time and frequency subject to minimum SINR requirements. We show that these additional constraints will not change the optimum strategy, but may affect the set of “on” or “off” transmitters. Also we present an approach that transforms the mixed zero-one nonlinear problem to an equivalent mixed zero-one linear problem at the expense of extra variables.
How to Approach to an Autistic Child? Pediatrician’s View
Mahmod Mohamadi
Iranian Journal of Pediatrics , 2003,
Abstract: After about two centuries from the famous monograph written by Jean-Marc Gaspard (French physician) and about six decades after the first descriptions of autism published by Dr. Leo Kanner, autistic children have a yet unexplored, strange world full of mysteries not only for the parents but also for the physicians involved in the management of these children. The mean age of diagnosis of a child with autistic spectrum disorder is as late as six years even in well-developed European countries. Pediatricians are the first who visit these children and they are also actively involved in their health care. What is the actual role of a pediatrician in a logical and practical approach to the problem? And also how could we promote early diagnosis? In the following review article, I am going to answer these questions, mainly by introducing a new checklist for early diagnosis as well as a guide for further requesting paraclinical examinations for the children with autistic spectrum disorders.
ANATOMICAL STUDIES OF THE VAGUS NERVE AND ITS BRANCHES TO THE STOMACH
Youssef Mohamadi
Acta Medica Iranica , 1980,
Abstract: 1. The oesophageal plexus is in the structure and arrangement"nof its larger branches constant."n·2 . Two trunks arise from the oesophageal plexus, the . anterior vagal trunk and the posterior vagal trunk;"neach trunk contains fibers of both left and right vagi nerves."n3. These vagal trunks in the majority of instances pass through the oesophageal opening of the diaphragm each in the form of the or two sterns."n4. Anterior and posterior gastric plexuses mayor may not be present: the one may be pr e s ent , the other"nabsent. If present. their formation is limited to the branches destined for the supply of the stomach."n5. The manner of distribution of the vagal branches is"nin the main constant."n6. The main gastric branches lie in the neighborhood of the lesser curature."n7. The anterior vagal trunk supplies the anterior surface of the stomach as far as the pyloric antrum; it does not supply the pyloric canal and sphincter through those branches which lie along the lesser curvature. This statement holds good for the posterior vagal trunk and the posterior aspect of the stomach."n8. The pyeloric canal, sphincter, and first stage of the duodenum receive their nerve supply from above, receiving twigs from the vagal branches to the liver."n9. Sympathetic fibers derived from the coeliac plexus reach all regions of the stomach. Twigs may be seen to unite with and run with vagal twigs.

Application of Genetic Algorithm for the Bin Packing Problem with a New Representation Scheme
N. Mohamadi
Mathematical Sciences Quarterly Journal , 2010,
Abstract: The Bin Packing Problem (BPP) is to find the minimum number of binsneeded to pack a given set of objects of known sizes so that they donot exceed the capacity of each bin. This problem is known to beNP-Hard [5]; hence many heuristic procedures for its solution havebeen suggested. In this paper we propose a new representation schemeand solve the problem by a Genetic Algorithm. Limited computationalresults show the efficiency of this scheme.

Abstract: This paper presents a framework of iterative methods for finding specific common fixed points of a nonexpansive self-mappings semigroup in a Banach space. We prove, with appropriate conditions, the strong convergence to the solution of some variational inequalities.
