Abstract
Background and Aim: The production of science is the key element of program to achieve sustainable development. Currently, the most important characteristic to produce knowledge is the number of document indexed from scientific journals in databases that do bibliometry and Scientometrics study. The aim of this study is evaluation of scientific production of Iranian medical domain based on the document indexed form scientific journal in chosen database, between 2005-2009.
Materials and Methods: Analytical- descriptive method and bibliometry analytic was adapted. The study population includes all scientific journals that was published in English and indexed in WOS and Scopus until of the time of this study. Data collection tool was check list that was made by researchers & complete by referring and direct observation in WOS and Scopus databases. Data was analyzed by SPSS and other statistical methods.
Results: Showed that from 44 journals title that studied, 18 titles was indexed in WOS and 20 titles was indexed in Scopus. The number of records and citation, according to the review with passing year, has been rising. Maximum number of documents and citations are related to the final years. Number of records in the Scopus database is more than WOS, but the differences in not significant (P- value = 0/186).
Discussion and Concoction: Journals visibility in the medical science filed in review databases in not desirable. Less than 50 percent of scientific journals were indexed in databases. Between the years studied, the scientific production of medical area of the country has been growing but to reach the proper situation, more effort is required.

Abstract
Background and Aim: Using Hirsch index as an important tool to describe the scientific outputs of researchers has caused some authors to increase their self-imposed parameters, increase, citing themselves. Therefore it is necessary to consider the effect of self-citation on Hirsch index for every author to have better measuring on the quality of researchers scientific production.
Materials and Methods: This research is descriptive method of citation analysis in general and specifically self-citation analysis. The study, are Iranian prolific authors in the field of medicine that have at least 30 documents indexed in Web of Science database between 2004 to 2006. Citations following up was studied till December 2010 Results was analysis using Excel software version 2007.
Results: The average self-citation observed between prolific authors in medical field was 25/89 percent. Hirsch index for 30/77 percent of authors had changed considerably. The authors rating scheme based on Hirsch index was done after removing self - citation so that 38/46 percent of authors decreased to lower level.
Conclusion: Considering that 10 to 30 percent of self-citation can be normal and justified, the status of self-citatin of Iranian prolific authors in medical field is desirable. Also, lower rates of self - citation of these authors doesnot affect Hirsch index.

Abstract
Background and Aim: Self-citation, as one of the limitations of citation analysis, unusually affects the ranking of journals. This study aims to evaluate the degree of relationship between self-citation and immediacy index correlation of Iranian medical journals indexed in Scopus Citation Index between 2005 and 2009.
Materials and Methods: The method of the study is survey-descriptive in which citation analysis is used. The study included all Iran-based English medical journals indexed in Scopus database up to May 2009. The control list was prepared and its validity was confirmed. Data were collected by referring to Scopus website and publication review resources, and analyzed by statistical software and appropriate methods.
Results: The findings showed that self-citation rate of journals was 29.64 percent, which comprised 14.43 percent of the total number of citations. There was a significant relationship (at the level of 0.01) between self-citation rate and immediacy index of journals (p = 0.591). Besides, Pearson correlation coefficient showed a significant relationship between the number of journals' articles and the journals' immediacy indexes excluding self-citation during the years of study.
Conclusion: Self-citation has a direct effect on journals' immediacy index that is, an increase in the rate of self-citation causes an artificial increase in the journals' immediacy index. On the other hand, immediacy index is affected by the number of journal articles. Therefore, the reduction or elimination of self-citation seems to be necessary for the journals and can put them in their right place.

Abstract
Background and Aim: In many countries, hospitals have triple ownership (governmental or public, for-profit, and not-for-profit). Numerous studies have been performed in order to investigate the differences among these hospitals in accordance to expenditures, presentation of uncompensated therapeutic services, number of outgoing patients and other measurement devices of hospital performance. The aim of this research was to investigate the role of ownership on total Factors Productivity changes in Qazvin`s selected hospitals.
Materials and Methods: Descriptive-analytic study was conducted in three periods of time from 2005 to 2007 in 8 selected hospitals of Qazvin. Inclusion criteria included the active beds and the value of intermediate consumptions in hospitals.The exclusion criteria included the total number of inpatient and surgical operations. Data collection tool, was researcher-designed checklist. Data were analyzed using DEAP 2/1 software and ANOVA, HSD and TUKEY tests.
Results: There was a significant difference between the mean productivity of three hospital groups due to the existence of various ownership(p=%012), Also a significant difference was observed between the mean of technological efficiency of the three groups of hospitals(p=%006), No significant differences was found between the mean of technical efficiency of the three groups of hospitals(p=%23).
Conclusion: Cause of the variation in total factor productivity in private hospitals, is due to their suitable production technology which is always improved. But in respect to their efficiency promotion and optimization of production and products, there was no distinguishing difference with other hospitals.

Abstract
Background and Aim: Materials and methods, as one of the most important
parts of a paper, introduces its scientific value. This study aims to investigate the
methodological quality of publications of Tehran University of Medical Sciences
(TUMS) indexed in PubMed.
Materials and Methods: In this descriptive, cross-sectional study, 400
articles affiliated to Tehran University of Medical Sciences and indexed in
PubMed until the end of 2012 were investigated. The type, purpose and subject
matter of all these articles were recorded in a checklist.
Results: The most frequently published reports were cross-sectional studies
(41.3%), followed by case-control studies (14.5%), case reports (14.3%), clinical
trials (13%), narrative reviews (4.8%), animal studies (3.3%), quantitative studies
(2.8%), quasi-experimental studies (2%), cohort studies (1.8%), case series (1%),
meta-analysis (1%), and systematic reviews (0.5%). When the articles were
classified according to National Library of Medicine (NLM) classification, most
papers were about musculoskeletal system (8.5%). Over half of the articles were
therapeutic (52.8%), followed by diagnostic (24.8%), prevention (12.3%),
prognostic (7.8%), and etiologic (2.5%). School of Medicine, Hazrate Rasoule
Akram hospital, and Endocrinology & Metabolism Research Institutes had the
highest number of articles among TUMS faculties, hospitals, and research centers.

Abstract
Background & Aim: Because of extension of health services and comprehensive receivers, the need for health services management is inevitable. Despite the availability of health care services, people do not embrace the full range of these services. This study was conducted to determine the reasons for unwillingness to use health care services presented to age group under 9 years from perspective of health workers in Qom province, during 2013.
Materials and Methods: This cross-sectional study was done to evaluate the perspective of health personals about services that presented to population with age group less than 9 years. This study was done with a questionnaire as a matrix evaluation of health services. Data were analyzed by Spss 15 Software. Chi square test were used for the evaluation of the hypothesis.
Results: The main reasons for the lack of interest to receive the health care services from perspective of health workers were: lack of health knowledge in recipients of services, inadequate information, poor methods of health care delivery, quality of health care and unsuitable access to health care.
Conclusion: To encourage people to get the health care services provided at health centers in Qom province should hold training meetings, to enhance the knowledge of health care recipients. About presentation of services and methods of service delivery in health centers, we should give enough knowledge to people. Also we should try to promote the level of services, while people motivate to get the services.

Abstract
Background and Aim: In the recent years the number of science research health journals has increased in Iran. These journals should be based on the standards and criteria required in international indexing database. The aim of this study was to determine the adaptation rate of structural requirements on the Iranian medical journals with the criteria of indexing based on Scopus indexing database.
Materials and Methods: This study was a descriptive-applied study done using bibliometric methods. The statistical population was all of the science research journals in health ministry on 2014. The data collection tool was the inventory control extracted from Scopus database. The data was collected and analyzed by SPSS20 software and descriptive statistics methods.
Results: The results showed that more than half of the biomedical journals were not based on the international editing statements and also, participation of the members of international editing committee was very low. The mean of international editing committee members was 83.3% and all of them were in Iran besides, participation of non Iranian authors was very low in these journals, with a participation rate of only 5.79%.
Conclusion: The Iranian medical journals did not follow the expected criteria in Scopus indexing database in a satisfaction level. Adaptation to the expected criteria can facilitate the entering and indexing procedures for these health journals in Scopus indexing database.

Abstract
Background and Aim: In this study, in order to increase the visibility of articles in Scopus journals of Tehran University of Medical Sciences (TUMS), selective dissemination of information (SDI) service was presented and its impact on some citation indices was investigated.
Materials and Methods: This is a semi-experimental study of two groups (pretest-posttest design with a control group). In this study, TUMS Scopus indexed journals (20 titles) were randomly divided into test and control groups and their citation indices were assessed. Then, the SDI services for test group journals were designed based on PubMed's Alert system and presented to the university's top researchers for one year. Finally, the citation indices of the journals of test and control groups were reassessed and compared. For data analysis, independent t-test, paired t-test and, covariance analysis were used.
Results: Comparison of mean citations as well as SJR, SNIP and CiteScore indices before and after the intervention showed no significant difference between the test and control groups. But the average CiteScore in both groups after the intervention was significantly higher than the average before the intervention.
Conclusion: The results showed that the provision of the aformentioned services in the time period defined in this study had no significant effect on the citation indices. However, the valuable experiences gained in this study will undoubtedly be applicable to future research as well as services to researchers, librarians, and journal managers.

Abstract
Background and Aim: Currently, utilizing different nutritional indicators to investigate the association between diet and various diseases is considered in previous studies, which is related with some chronic diseases. However, no studies have studied the connection between the indicators with the rate of metabolism at rest (RMR). Therefore, the present study aimed to determine the relationship between dietary index and insulin load with resting metabolic rate (RMR) in overweight and obese women
Materials and Methods: A total of 280 healthy overweight and obese women (aged 18-50 years) who were referred to community health centers of Tehran University of medical sciences were included. In this study anthropometrics measurements such as weight, height, waist circumference, waist to hip ratio, body mass index, fat percentage, and fat-free mass were evaluated for every participant. Data on dietary intakes were collected using 147 semi-quantitative food frequency questionnaire (FFQ). DII and DIL were calculated using food insulin index values published earlier. To assess the RMR, indirect calorimetry was used.
Results: Mean age of study participants was 36.4±8.38 years. Although a significant association was seen between DII and RMR in a crude model (P=0.04); adjusting for different confounders made this significant relationship between DII and RMR insignificant. In addition, the dietary insulin index had no significant relationship with the amount of RMR/kg (p=0.63) and RMR/FFM (p=0.73).
Conclusions: Based on the results of this cross-sectional study, it seems that the insulin index and insulin load of the diet are not associated to the rate of resting metabolism. However, due to the limitations of this study, findings can only confirm or reject the hypothesis under further studies. It is also necessary to determine the role of dietary insulin indicators on human health, especially with a Study Prospective Design
