تأثیر آموزش بر آگاهی و نگرش آرایشگران شهر بیرجند در زمینه ایدز در طی سالهای 1387-1386 (گزارش کوتاه)
Background and Objectives : With no cure or effective vaccine , education is the only means of controlling AIDS . Barbers and beauticians can play an effective role for preventing and controling disease. Therefore this study has been done to determine the knowledge and attitude of Birjand barbers and beauticians about AIDS. Materials and Methods : This quasi experimental (before-after study...
OBJECTIVES To determine whether digital signal processing (DSP) hearing aids produce conducted radio frequency interference that can affect the use of personal FM systems, to quantify the nature of any such interference, and to discuss practical remedies. DESIGN Sixteen DSP hearing aids were used. Measurements were made of the spectral characteristics of any conducted radio frequency interfer...
Background: AIDS, one of the most perilous infectious diseases which has killed lots of victims all over the world. Considering the fact that nowadays, this disease is incurable, the only way of challenging it, is prevention. Since student nurses are in continuous contact with these Patients. A survey is conducted to assess their knowledge and attitude towards HIV and AIDS. Objective: To deter...
Distributed System design is a highly complicated and non-trivial task. The problem is characterized by the need to design multi-threaded, multi-processor, and multi-media systems. Design frameworks such as Open Distributed Processing (ODP), the ITU/ISO standard, provide significant, theoretical, guidance and aids towards the provision of successful distributed system designs. The purpose of th...
We present a study about the use of current electronic travel aids to help blind people navigate through familiar and unfamiliar environments. We also discuss the main strengths and weaknesses of electronic travel aids and propose guidelines to design and use them adequately. We provide a proposal to develop and use traveling aids. As a result, this can be a first step towards defining major as...
