The purpose of this study is to identify the relationship between Internet of thins . on organizational performance by considering intermediate role of knowledge creation.
This is a descriptive-correlational study. This is a descriptive-correlational study in the statistical society of Tehran's Mehr Bank, consisting of 1050 people. The sample size of 284 people was selected using a simple random sampling method. Using a questionnaire it placed. The internet questionnaire was collected. (Azzuri et al., 2010) and the performance questionnaire (Shamei et al., 2012), and the creation of knowledge derived from (Bijongo et al. 2003, 23).
Finding: The findings of the study indicate that there is a significant relationship between the relationship of the Internet of things on organizational performance by considering intermediate role of knowledge creation in the Mehr bank of the province of Tehran.
The expansion of the services of the Bank of the Eghtesad to the Internet of Things increases and improves performance

Purpose of the present paper was to identify prolific and influential researchers in digital library domain in Iran. It tries to determine the extent of research collaborations of the scientific community of Iranian digital libraries (DLs) domain in scientific conferences and journals.
This is a scientometrics applied study. In this regard, Social Network Analysis (SNA) methods were used to analyze and visualize the co-authorship structure. The statistical population of this research includes all researchers affiliated with Iranian institutions which wrote at least one Persian or English languages paper up to 2016 in the DLs domain. Microsoft Excel, RavarMatrix and UCINet softwares has been utilized to analyze the collected data. Also, NodeXL and VOSviewer softwares were applied in order to mapping the co-authorship networks.
Findings: Researchers productivity is not in agreement with Lotka's Law; In addition, the findings showed international collaboration that the low level and dominant authorship pattern in DLs domain papers is a two-author model. Overall and by taking into account the average rating of all scientific production and SNA indicators, respectively Mehdi Alipour-hafezi, Yaghoub Norouzi, Saeed Rezaei Sharifabadi are Iranian key actors in the DLs domain.
Co-authorship network of DLs domain in Iran, seems to exhibit “scale-free” network properties and the very low density of the network also indicates the inadequate maturity of the researcher's social structure; However, still the Milgram's six degrees of separation theory is verificatied about this community and the utilization of the term “small world network” it's permissible.

Research social networks having capacities such as communication and dissemination, have drawn the attention of researchers. It seems that new means are required to assess studies published on this medium.
Research This research, using the Altmetrics method, investigates the compatibility of RG score with citation indexes. To collect data, the names of all faculty members of the University of Tehran’s College of Engineering were searched in ResearchGate. It revealed that 231 of them are members of ResearchGate and have RG score. Next, the members’ h-index was searched in the Web of Science, Scopus and GoogleScholar to assess the alignment between the RG score with these three indexes. Spearman’s rank correlation coefficient test was used for the assessment.
Findings: According to the research findings, the correlation between the h-index taken from Web of Science and the RG score is 0.844, while the correlation between the h-index taken from Scopus and the RG score is 0.859 and the correlation between the h-index taken from GoogleScholar and the RG score is 0.820.
Hence, there is a meaningful statistical correlation between RG score and h-index. The highest correlation is seen between the h-index taken from Scopus and RG score. Therefore, RG score can be used as a complementary criterion for assessing researchers’ scientific activities.

The purpose of current research. Was to investigation the librarians’ usage of library software capabilities network, search, and circulation in Ahvaz special libraries.
Research was applied in terms of its aim and analytical survey of the method. The survey population included the total 74 librarians in Ahvaz special libraries; due to limited number of librarians, no sampling was applied. Data gathering instruments wre a questionnaire based on Davoodzadeh Salestani (2003) and Oliaeinejad (2012) questionnaires. And for data analysis, independent t test, one way ANOVA, Pearson and SPSS 22 software were used.
Findings: The findings showed that libraries mostly use the library software capabilities in network, searching and circulation. As a whole, the network capabilities and circulation services were used the most; and searching in terms of average use of library software capabilities, was used the least. Analysis of demographic characteristics showed that gender, years of service and field of study had no significant difference on the usage of library software capabilities by librarians. But from age point of view was significant.
As a whole librarian have a good ability in using network and circulation of library software's capabilities. However, in searching it is necessary to inform and teach librarians about the capabilities of the software; also, the library software designers need to evaluate and redesign the software to match the librarians’ needs.

Purpose of this research is to investigate information technology's infrastructure for implementing knowledge management in the audiovisual archives of IRIB inQom . The reason for selecting the place is reliance and dependence of tasks to the information and specific knowledge.
The method of the research is Analytical Survey. Measurement tool in the research is an organized questionnaire consists of 34 questions which were tested by Cronbachsalpha 0/849. The data in statistical tables and charts have been appropriate to describe the data Keregsi and Morgan determine by 127 persons and data selective is on the basis of accidental measures. The data analysis has done by SPSS software and single specific T-test is used.
Findings: The results of the research showed that characters such as knowledge Creation and implementation are suitable with the medium of 17/5 and 18/4 respectively. The recorded compilation is in the medium level of 15/5 knowledge tranfer is less suitable by the medium of 14/1 and totally the technology infrastructure for knowledge management in the audiovisual archives of is with the high rate of 46/4approperiate.
The results of the research showed that there is meaningful relation between the technology's infrastructure and General knowledge management Model (creation, recording, transfer and implementation) for using knowledge management in the archive of.

The aim of this study is to investigate factors which influence the articles be retracted.
This study was an applied study and survey. It used scientometric method and content analysis approach. All of 109 items of Iranian retracted articles between 1997 -2017 were retrieved in Scopus to be analyze in Scopus, Google scholar, and Research gate.
According to the current study, number of retracted articles did not scale up or down in a significant pattern and the pattern rate of retractions just depends on the quality of the articles and they cannot be expunged from the search cycles. Some altmetrics indicators such as reads and citations in research gate showed the effect of retracted articles on the authors and their way of research, so they cannot be remove from the scientific resources even if we retract them.
Moreover, most of articles are retracted because of authors’ faults or invalid Functions in reviewing stages. Medicine is the main subject which has the most retracted articles and Physics and astronomy, Computer science, and Earth and energy sciences have the list number of retracted articles. So, publishers can concentrate on these subject areas to know the possibility of retractions
