'Voluntary activities' domain in public libraries is a very important and expanding topic; so that many librarians are exploring new ways to use and retain volunteers. The main purpose of this study was to determine the effective factors on preservation and maintenance of volunteer working in libraries affiliated with Astan Quds Razavi.

This applied research was conducted by survey method. The statistical population includes 200 volunteers working in the libraries of Astan Quds Razavi, which with the Cochran's formula, 131 people were determined as the sample size. A simple random sampling method was used to select the sample size of the research. The data collection tool is a researcher-made questionnaire. The model used in tool design is a three-branch model that has three main components: structural factors, behavioral factors and underlying damages. The validity of the tool was done with the opinion of information science and knowledge experts and librarians with voluntaries staff and the internal coordination of the questionnaire items with Cronbach's alpha coefficient was confirmed.

Research findings showed that among the sub-components related to structural factors, the sub-component of organizational structure had a higher priority and at the end was the service compensation system. Among the components of the behavioral factors, the sub-component of the motivational system had more priority for the volunteers, and then the organizational culture and the characteristics of the managers had the next priorities. From volunteers's point of view, behavioral factors are more important than the other two factors, and from this approach, structural factors are ranked last. It was also found that there is a positive and significant relationship between all sub-components related to structural factors and behavioral factors. Also, a positive and significant relationship was observed between the three investigated factors.

The impact and relationship of all organizational factors on the maintenance of volunteers, shows that the respective managers should have a comprehensive view on the issue of management of volunteer forces to be able to use their maximum capacity in Astan Quds libraries. In the organizational structure, attention should be paid to the determination of their position and role, while removing the strict rules on the employment of volunteer's forces. The incentive system also plays an important role in attracting and keeping volunteers, which should be taken into consideration. In order to attract and retain volunteers, managers should take measures to strengthen the sense of belonging among volunteers and optimize their capacities; otherwise, the human force that can be effective in reducing the various costs of the organization will stop volunteering after some time.

TDue to the increasing significance of natural gas in the global energy portfolio and also Iran being the holder of second most natural gas reserves in the world the importance of managing the production and consumption of natural gas is an apparent fact Therefore underground gas storage USG technology as a tool of gas reservoir management could play a considerable role in the future of the gas industry in Iran Nevertheless the growing trend of attaining key technologies in this field has experienced a standstill In order to analyze and plan the development of this technology there is a need to discover the roots of the problems and failures which hinder this development and also to analyze them This paper aims to provide a framework for analyzing such problems using the approach of technological innovation systems Furthermore the effect of contextual and environmental factors on the development of this technology has been discussed Finally using the structural equation modelling method the relationship between contextual structural and functional factors of the technological innovation system of USG has been tested In the end it is determined that contextual factors directly and also indirectly affect the performance of the mentioned system by influencing structural factors to the extent that the intensity of effects on functions caused by contextual factors is greater than that of structural problems

This paper aims to determine the influence of contextual factors on information seeking behavior. This survey investigates search tactics used and users’ perceptions of the search results on the Web by postgraduate students at Kerman University of Medical Sciences. This study was conducted through a mixed method. Thirty postgraduate students voluntarily participated. The study was carried out in the first semester of the academic year 2012-2013. The data was gathered using two questionnaires and log files recorded with Camtasia Studio software. The findings indicated more than half of the participants (53.3 percent) used Google, short queries were more used than long queries, advanced search options were used rarely (23 percent), and the participants view few search result pages. According to the results, the contextual factors significantly influenced the search time, search tactics (including querying and navigating) and users’ perceptions of the search results (including ease of use, usefulness, satisfaction and relevance judgment). Navigating tactic was primarily used by the participants. Among different aspects of users’ perceptions of the search results, ease of use and relevance judgments were significantly different based on the contextual factors, whereas scanning, extracting, and confidence were less affected by the contextual factors. The findings suggest practical implications for information retrieval systems designers that can design of systems with better user interface in order to meet the needs of users with different knowledge and skills, in this way it leads in promotion of search process and improvement of search results quality.

The current study aimed to identify the effective aspects and factors on knowledge culture. It further strived to present a model for explaining the relationship between knowledge culture and effectiveness of knowledge management procedures in a knowledge-based organization. The study used a mixture of library and documentary studies، and exploratory mixed methods. First، the literature was reviewed to extract the effective aspects and factors on knowledge culture and the conceptual model was developed. Then، a questionnaire which was validated through eliciting the comments of experts and examining the status of knowledge management in the organization was distributed to the researchers who were randomly selected to be included in the sample. The collected data were examined through AMOS and SPSS software. The possible relationship between the components of the model was investigated through posing five hypotheses and correlational coefficient test. The results of structural equation modeling demonstrated a significant positive relationship between contextual factors and aspects of knowledge culture and between knowledge culture and the knowledge management effectiveness. Evaluating the variables of the conceptual model revealed that staff members’ characteristics، information technology and job characteristics would make a significant positive impact on knowledge creation and knowledge sharing. However، these factors had no significant influence on knowledge cooperation and knowledge learning.
