Purpose of this study is identifying the status of situation of security and protection of resources and equipment in Shahid Beheshti University Libraries.

applied research is conducted with survey method. Information gathered and analyzed from libraries’ managers of Shahid University.

The results showed that the most stolen equipment and supplies were, pages, images and maps in the books, and most preparations used to protect and preserve the library collections the care and conservation of building libraries against all types of thefts during the hours the holidays.

The status of the security of resources and equipment against theft in central library and the document center and attached centers in Shahid Beheshti University is good. Of course by revising the regulations of the security issues of each library seems necessary and should be updated.

 To compare the application of econometric methods in the economic valuation of central library services.

 Conditional valuation with the stated priority technique and econometric methods such as linear regression, logistics, probit, and Hackman have been used. The statistical population of central library users, which was selected using the sampling method, cluster, two-stage, 10 libraries, and the sample size was calculated using the Michelle-Carson formula at the level of 85% of 854 people. The data collection tool was a two-dimensional researcher-made questionnaire with 40 questions that had face validity and reliability with Cronbach's alpha of 0.83.

 In examining the effectiveness of each variable, the amount of change in the predicted probabilities of the dependent variable of the model (willingness to pay users) per unit of change in the variable (while the other variables are constant) showed that between the explanatory variables There is no correlation used in the models so that the two-to-two correlation coefficient of any of the independent variables was not more than 54%.

 Demographic and individual factors are more effective than other factors on people's willingness to pay. Based on the weighted elasticity of the income variable, if other factors are constant, a 1% increase in respondents' income increases the probability of accepting the proposed amount by more than 70%. No significant difference was observed in the results of logit and linear probit methods. Hackmann's two-step method, although it can differentiate between the factors affecting the acceptance of willingness to pay and the factors affecting the amount, in general, the willingness to pay was less than the other two methods.

the objective of this research is to identify the common threats and vulnerabilities in IoT and offering security policies to cope with them.

the methodology of this research is applied based on its objective, and descriptive-surveying based on data collection. The statistical population includes all exerts and professors of IoT in universities of Tehran with 50 members. The sampling method was convenience non-random. The sample volume detected was similar to the statistical population. The research tool was the researcher-made questionnaire from the systematic study of thematic literature. The validity of the questionnaires was obtained by referring to the experts of the IoT field. The reliability of the tool was 0.88 using Cronbach’s alpha coefficient for the questionnaire. Data was analyzed using descriptive and inferential statistics by SPSS software.

Although various standards have been developed in the field of security and confidentiality in IoT, the security needs of IoT and even its risks have not been still identified and analyzed. In addition, it needs confidentiality mechanisms, accuracy, authentication, and access control precisely. According to the findings of the tests of this research, vulnerabilities can be classified and cited in 21 groups.

the results of tests show that various experts based on their landscapes and activity fields determined a varied set of security policies to cope with Internet threats in the IoT field. However, the most important security policies against the security threats in IoT include mutual and efficient authentication, access control, secure architecture configuration, encryption of communications and data, chronology, and monitoring by concluding the provided ideas.

Performance assessment of Tehran Municipality Cultural and Artistic Organization libraries using Balanced Scorecard

The population of this study are included whole of staffs and managers and also users in the Tehran municipality Cultural and artistic Organization libraries and also 214 the users and 165 permanent staffs and 96 people through the managers. The data are collected through a researcher semi-structure questionnaire which is done by Ms. Nabizade and it’s titled “Evaluation of performance the general office Information in National library I.R. of Iran respect to Balanced Scorecard” then the data analysis and interpretation and it is used one way T-test for testing the questions.

The results show that the operation of the Tehran municipality Cultural and artistic Organization libraries through three perspectives which are the customer and the internal process and financial balanced through one other perspectives which are the growth and learning imbalanced.

Performance is balanced in the three perspectives of "internal processes", "customer satisfaction" and "financial" and in the perspective of "growth and learning" is unbalanced.

The aim of this study was to investigate the role of intellectual capital in attracting knowledge and organizational performance in the Cultural and Artistic Organization of Tehran Municipality.

The present study is descriptive-correlational in terms of the type of research method and applied in terms of purpose. Cronbach's alpha method was used. Cronbach's alpha coefficient with 0.91 for intellectual capital, 0.92 for knowledge acquisition and 0.86 for organizational performance indicates the high reliability of the questionnaires. Academic experts as well as managers of the studied community have been used. Descriptive and inferential statistics have been used to analyze the data. In descriptive statistics, information was provided (frequency, percentage, abundance percentage). In inferential statistics, correlation coefficient and Pearson test were used. The data were analyzed by SPSS software version 23.

In the present study, it was found that 33% of the employees of the organization have the highest level of work experience between 5 to 10 years and in terms of education level, the highest level with 54% frequency in master's degree and 63% frequency indicates the predominance of men. Regarding women in the municipality's cultural and artistic organization, the first to fourth hypotheses of this study are also confirmed.

It showed that the relationship between intellectual capital on knowledge absorption, the relationship between knowledge absorption on organizational performance and the relationship between intellectual capital on organizational performance, had a significant relationship. Also, other results of this study indicate that knowledge acquisition has very little effect on organizational performance as a moderating variable compared to intellectual capital.

This paper describes the emerging semantic-social concepts in digital libraries and explores the potential use of semantic web technologies.

The present study is a qualitative and analytical-explanatory one that uses Michel Foucault's theoretical (paleontological) contexts to evaluate changes in the semantic web domain.

The present study, after examining the challenges of semantic web implementation and access to semantic tools and services, demonstrates the benefits of applying standards (RDA and RDF), and thus provides a brief classification of tools and services. Semantic services are provided. In addition, a checklist has been suggested to further evaluate semantic tools, services, and projects.

Given that digital libraries will hold a huge amount of future data, As a result, the use of semantic web standards and technologies in digital libraries offers a new level of flexibility, interaction, interoperability and knowledge sharing and enhances their capabilities, so it is necessary to use from semantic web standards and tools. In semantic web a framework will be presented that every subject can be defined according to its special features, also these subjects among a net of communications have a possibility of adding a new or related meaning. Through semantic web, social semantic digital libraries will present a new level of capabilities, increasing cooperation& mutual communication, and sharing knowledge.

 This study aims to "study the behavior of Open Access among faculty members of universities of Ahvaz base on Ajzen and Fishbein model" is done.

 The method of causal modeling or structural equation model. A sample of 298 faculty members of universities in Ahvaz of public universities, Azad and Payamnour universities. Data were collected using a questionnaire based on the Ajzen model. The confirmatory factor analysis and structural equation modeling to assess the structural model was used based on the Diagram of LISREL software. 

 The results of the structural equation model is the relationships established in the form of beliefs and attitudes of behavior, attitude and behavioral intention and behavior, subjective norms normative beliefs, subjective norms with intention, intention, and behavior, beliefs controlled by controlling the behavior guidance By controlling behavior directed by intention and behavior, beliefs, behaviors and beliefs controlled, behavioral beliefs and normative beliefs, normative beliefs and beliefs controlled. The poor fit of the model was assessed at the beginning but after some relation to proposed changes to the software achieved a good fit. Compared to the Ajzen model, 4 relationships have been found.

Planned Behavior Pattern is a reliable model for planning and guiding the behaviors of audiences, students, and faculty members toward the use of electronic database services.
