Background and Aim : The Prevalence of AIDS is increasing in the World. To prevent, most scientists believe in public education. It seems that the quality of learning extensively depends on the quality of education. Since teaching method is one of the most important factors, we decided to compare the effect of three methods on the level of knowledge abut AIDS among high school students in Gorgan, northern Iran.

Materials and Methods: This pre-excremental study was carried out on 88 randomly selected junior high school students in Gorgan, Iran. The subjects were asked to fill out the questionnaire before and after the two-week treatment. The data were analyzes by t-test and Tooki Test.

Results: There was no significant different between control and pre and pamphlet group. While in both lecture group and combined group (lecture and pamphlet), the difference was significant .Using Tooki test, the difference between control and lecture group and between control and combined group was significant (P<0.05).

Conclusions: In order to increase the student's knowledge about AIDS, According lecture method accompanying with pamphlet is one of the best procedures.

Background and Aim: Homogeneity and Oneness is the feature of abstracting. These can't be achieved, without adherence to guidelines and international standards. The purpose of this study is evaluation of compliance abstracts of Persian-language journals of Tehran University of Medical Sciences, with ISO 214 & Vancouver's group guideline, in year 2009.

Materials and Methods: Survey-descriptive method was adapted. The study sample included all full-text journal Reviews in English Persian language belonging to Tehran University of Medical Sciences. These journals were significant in TUMS website to date (30/2/2009). Total 100 abstracts from the latest issue of the journal articles for instance, were randomly selected. The data collected through two control lists separately, reflecting the standards of ISO 214 and instructions group in Vancouver for abstract writing. The data were analyzed by software and statistical techniques.

Results: The average overall rate of compliance with ISO standards Review is 85/37 percent (SD 24/93 percent), and group instructions Vancouver is 84/44 percent (SD 24/36). Review of the "express findings" had the most and the "sub results presented" had minimum compliance with ISO standards. The "keyword existence" and "noted the findings" had the most and the "being derived from the headings keywords subject had "minimum compliance with the instructions in Vancouver group.

Discussion and Conclusion: The abstract compliance with ISO 214 and Vancouver instruction was desirable. More comply from ISO 214 in "results presented" and Vancouver group instruction in, keywords subject in medicine seems to be required.

Background and Aim: Despite the information regarding CAD risk factors, there isn't agreement between the relation of this risk factors and coronary artery diseases. This study was done for determination of related factors with vessels involved in coronary artery angiography.

Materials and Methods: In this descriptive and analytical study, 2390 patients' .were selected via census sampling from Kosar Angiography center in the Golestan province. Data gathering form included data such as age, gender, body mass index (BMI), blood pressure, diabetes, smoking and opiates addiction history. Vessels involved were determined by angiography. Data analysis was done with one way ANOVAs and logistic regression using SPSS 16 soft ware.

Results: Mean and standard deviation of patient's age was 57.9±10. 58.2 percent of them were male. There were significant correlations between age, gender and BMI with numbers of vessels involved. Male gender(OR=1.329), hypertension (OR=1.25) and diabetes(OR=1.20) increased the probability of more than one vessels involvement. Regression analysis showed there were no significant correlations between age, BMI, smoking and opiates addiction history with more than one vessels involvement.

Conclusion: Our finding confirmed that male gender, hypertension and diabetes are the main risk factors in involvement of more than one vessel.

 Background and Aim: Personal Information Management (PIM) is a novel approach comprising three interactive parts of information resources, dimensions, and tools. The main aim of this study was to determine the degree of Tehran University of Medical Sciences (TUMS) management and information science students’ familiarity with PIM process.

 Materials and Methods: The present work is a qualitative-applied study and the population includes 145 TUMS management and medical information students in 2012. The subjects were randomly selected and the data were finally obtained from 73 persons through semi-structured interviews. The data collection tool was a questionnaire with 10 open-ended questions classified based on the conceptual framework  of interviews. The questions were about how to acquire, organize, maintain, and retrieve information. To analyse the interviews, the qualititative data analysis software Nvivo 8 was employed.  

 Results: According to the obtained results, 51% (37 persons) of interviewed persons have applied methods and tools in order to organize and maintain information and have had exclusive methods to retrieve information. The most frequent worries were the information storage 49% (35 persons) and acquiring information 29% (21 persons).

 Conclusion: It is noteworthy to say that the PIM approach is not very popular among university students, and many of them acquire, maintain, and organize their personal information inappropriately in spite of their need for the method. Therefore, educating the students and promoting their performance can result in the improvement of main PIM-related problems.
