آرزو غمگسار

One of the most important infrastructures for the development and progress of countries is scientific outputs and targeted research to meet the needs of society and reduce the disease burden. The aim of this study was to determine the relationship between the number of scientific outputs indexed in PubMed, related to ten diseases with the highest mortality rate in Iran and the burden of each disease in 2000-2017.

In this applied study with a scientometric approach, firstly, the data on ten diseases with the highest mortality rates, in order of rank, in Iran were obtained from the University of Washington's Institute for Health Metrics and Evaluation. Next, two health indicators, the number of lost years due to disability or death and disability caused by diseases and injuries related to each disease was extracted from the relevant site. Afterwards, using the controlled terms as the subject of the mesh, the related words with their synonyms in each disease were documented and then searched. Descriptive statistics was used to calculate the descriptive indicators and Pearson correlation test was applied to determine the relationship between the variables.

The findings showed that as the years progressed towards the present time, the number of scientific outputs related to ten diseases with the highest mortality rate in Iran increased, but it was relatively fewer in some diseases such as maternal and neonatal disorders, chronic respiratory diseases, transportation injuries and unintentional injuries. There was no relationship between the number of articles in the studied time periods and variables of disease burden. The trend of changes in the number of scientific outputs in ten diseases with the highest mortality rate in Iran and burden of each disease was not the same.

Although health researchers have done numerous quantitative researches, many of them have not been solved the problem, and it seems that the researches have not been guided in the right direction. Problem-based research is not designed. Grant allocations have not been based on the facts at the universities and research centers. Professional management of academic research must be created to meet the real needs of the community. Moreover, medical universities can perform their research based on these priority topics.

Back ground and Aim: Digital libraries provide suitable substrates for use in the field of electronic information resources. Obtain and introduce of electronic resources to targets may be challenging for operators. Thus, the objective of this study is to determine awareness, use and Satisfaction of dental assistants of Iranian Medical Digital Library.
This is a descriptive study conducted among 267 dental assistants at Tehran, Shahid Beheshti and Shahed Universities of Medical Sciences used census to recruit participants used a self-designed questionnaire to collect data. Validity of the study instrument was investigated by faculty members in Medical Information Sciences and its reliability was assessed by Cronbach's alpha of.88.
180 (80%) of dental assistants were aware of Iranian Medical Digital Library. A majority of respondents used it from home and the library of college. Most of them used Iranian Medical Digital Library for their research work. The largest number of them studied 1-2 resources per week. The level of satisfaction was moderate.
Level of awareness from Iranian Medical Digital Library was suitable. Educational courses in clinical dentistry could be accelerate to achievement of articles and digital sources. Also, encourage students to use these resources for those did not aware and use them. Level of usage and satisfaction were lower than moderate.

Scholars of different fields need open-access and subscribed electronic resources to access scientific information. However, with the increasing growth of electronic resources and the replacement of printed materials with digital collections, the way we access these resources has changed significantly. Thus, the objective of this study was to assess how dental assistants at Tehran Universities of Medical Sciences, Shahid Beheshti Universities of Medical Sciences, and Shahed Universities of Medical Sciences access and use electronic resources.
This was a descriptive-analytical study. The statistic population consisted of 267 dental assistants at the abovementioned universities. The data collection tool was a researcher-designed questionnaire. The validity of the questionnaire was confirmed by faculty members in the field of Medical Librarianship and Information Sciences and its reliability was approved using Cronbach's alpha (α = 0.88). The collected data were analyzed using one-way ANOVA and Kruskal-Wallis test.
ScienceDirect and PubMed were the most used electronic resources among subscribed and open-access databases, respectively. Participants most often used the subscribed resources which were available at work or home. The respondents reported low internet speed as their most important barrier to accessing information.
Dental assistants used subscribed resources which were available at work or university more than others in order to access the full text of subscribed electronic resources. Improving technology and Internet broadband infrastructures would also help decrease the limitations and problems in accessing required information.

Considering the elements of knowledge management (availability, creation, and transfer of knowledge) is very important in digital libraries websites and makes the performance better. So this paper aim to identify the knowledge management criteria in Iranian selected digital library's websites and study of observance scale
The research method was descriptive survey and from applied research type. Data collecting has been based on check list according with K-ACT model (Knowledge- Access Creation Transfer). The population of this study was 7 digital library websites, including Noor, Payame noor, Islamic Parliament, Tebyan, DID, National Digital Library of Iran and Astan Quds Razavi that were selected based on accessibility.
This research findings showed that use of knowledge management criteria in the selected digital libraries websites is moderate and the access to website criteria is highest and lowest is online participation criteria. Tebyan DL earned first rank among seven libraries with 56 percent compliance with the standards of knowledge management in the digital library's web sites.
Study of knowledge management criteria in the selected digital library websites has shown that these criteria has not been favorably applied that it stems from criteria incompatible with the principles, rules and standards. Due to these problems, designers of digital libraries can be effective in promoting these websites and enhance the quality of digital library services with aware of users’ needs and attention to use of these criteria.
