Knowledge is the axis of value creation in today's organizations. Knowledge management as a strategic capital of an organization is considered the most important organizational advantage. On the other hand, the importance of sharing the experiences of librarians to each other in order to perform their professional duties, shows the role of knowledge transfer and sharing methods among librarians. These days, improving the performance of the organization is a response from an organization to face the challenges that arise from the rapid global transformations. From the organization's point of view, this challenge includes responding to the needs of customers and providing goods or services with a high degree of efficiency and in an efficient and effective manner. From the perspective of organizational members, this challenge includes improving the quality of work life. So that the organization is a pleasant and satisfying place for work and effort.This paper examines the state of knowledge sharing among managers and librarians of public libraries in the city of Ahvaz. Every organization has its own culture, which is influenced by the culture of the organization's people. In this research, it has tried to measure the effect of culture on knowledge sharing in the form of components such as competition, motivation, support, cooperation, trust, etc.Research questions are:What is the culture of knowledge sharing among the employees (librarians and managers) of Ahvaz public libraries?What are the different methods of sharing knowledge among the employees (librarians and managers) of public libraries in Ahvaz?What is the status of information and communication technologies for sharing knowledge among public libraries in Ahvaz.

Literature Review:

Literature review shows that there is a positive and significant relationship between organizational culture and knowledge sharing in many studies. For example, a study by Burnette (2017) aims to explore the nature of tacit knowledge (TK) sharing among library colleagues, with a focus on the characteristics of TK and contextual factors such as organizational culture or the mentor/mentee relationship. Three thematic areas emerged. First are the influence of organizational culture and the importance of trust in knowledge sharing behavior. Second, the value of teamwork and the significance of mentor/mentee roles surface as significant drivers of TK exchange. Last but not least is a better understanding of the nature of TK, as it relates to types of knowledge and characterizations of experience and expertise.

This is an applied research and has been done by survey. The statistical population was all employees (managers and librarians) of public libraries in Ahvaz City and the implementation time was 2022. A researcher-made questionnaire was used to collect data, and the content validity of the questionnaire was obtained by experts' opinion and its reliability using Cronbach's alpha (0.90) and dividing it into two halves (0.85). In analyzing the questionnaire data, descriptive statistics techniques were used for demographics, and techniques such as one-sample t-test and Friedman's rank average test were used for the questionnaire's inferential questions.

In terms of the components of sharing culture, the competition between employees for sharing knowledge with the highest average (3.16) has the best status, and the managers' motivation to share knowledge with other libraries is the lowest with an average of 2.70. Also, the state of knowledge sharing in terms of different methods of knowledge sharing shows that the most favorable state is related to courses and workshops with an average of 3.55, followed by the enterprise resource planning (ERP) with 3.51, as well as the quality of personal communication and informal among librarians with an average of 3.26. The findings show the status of knowledge sharing and communication technology from the point of view of the managers and librarians of public libraries in the city. For instance, while training courses and workshops and personal and informal communication between librarians, as well as administrative automation are good, other things such as employee performance and the culture of knowledge sharing are less favorable. Cases were found where there was a lack of awareness of the importance of knowledge sharing and a lack of organizational support.

The results of the current research show that information and communication technology and then knowledge-sharing methods are in a more suitable situation than the categories of employee behavior and knowledge-sharing culture. According to the findings regarding the knowledge-sharing methods, where Friedman's test was used, the highest average rating was given to the method of sharing and exchanging knowledge from courses and workshops with an average rating of 9.63 with a deviation of 0.78. The next ranks were administrative automation system with an average rank of 9.43 and personal and informal communication between librarians with an average rank of 8.46. Finally, the knowledge management system with an average rating of 5.36, publications and bulletins with an average rating of 5.30, and public libraries with an average rating of 4.67, have the lowest average, which should be used by examining the problem of the degree of its solution.Overall, this study shows there is a need to improve information technology and the culture of knowledge sharing.

Recognition of hand writing on paper, on display or on air is an important challenge in computer vision. Air-writing recocognition is especially difficult due to three dimentionality of space. In this research work the aim is recognizing persian digits which are written in air in front of a Kineckt sensor using a fingertip and the sensor can detect the digit using its depth image. For hand and fingertip segmentation we use K-means algorithm. To extract the features we use a novel method called slope variation detection, and to classify the features Hidden Markov Models (HMM) is used. Recognition rate of Persian digits using a local database with 10 times mutual validation is 96%. This novel method was compared with some other similar methods in the literature . The results confirm relative priority of the proposed method.

By progression of sedentary life style in societies, increased obesity related metabolic disorders such as metabolic syndrome, insulin resistance and diabetes. Metabolic syndrome as a precursor of other chronic diseases targeted for special consideration as a worldwide public health challenge. Metabolic syndrome accompanied with a collection of risk factors like abdominal obesity, glucose, triglycerides levels, blood pressure and HDL deficiency. Etiology of metabolic syndrome is a complex and that is caused by the interaction of genetic and environmental factors. Due to lack of studies on military personnel, this study, investigated prevalence of metabolic syndrome in four age group among air guard personnel.
Methods and Materials: This cross-sectional study was conducted in 2015. During the study, Fasting glucose levels, blood lipids, weight, height, body mass index, waist circumference and blood pressure were measured between 1, 000 air guard officers that referred to annual health monitoring program. Then, the prevalence of metabolic syndrome was assayed with two International Diabetes Federation (IDF) and Adult Treatment Panel III (ATPIII) criteria.
The data show that12 participants (1.2%) were under high blood pressure, and 56 (6/5%) were at risk for high blood pressure. Due to High levels of body mass index and waist circumference, 5 (0.5%) of officers were at risk of diabetes. Abnormal triglycerides and cholesterol were measured in 411 (41.1%) and 100 (10%) participants respectively. Serum HDL levels, body mass index and waist circumference was determined, and the results show that in 110 cases (11%) and 29 (9/2%) 110 (11%) respectively positive to metabolic syndrome risk. Finally, according to IDF criteria, 44 patients (4.4%) and ATPIII criteria, 32 cases (3.2 %) were identified as metabolic syndrome
Discussion and Despite the relatively high prevalence of metabolic syndrome in our country, The results show that incidence of metabolic syndrome risk factors among the officers of air guard is in low levels which may related to, military lifestyle. Due to the link between metabolic syndrome and other complications, the three golden orders: increased physical activity, weight control, and diet are suggested for prevention. A comprehensive program to train susceptible cases and treatment strategies is recommended.

we aimed to assess the level of service quality in the central library science and culture using standard tools LibQual, examining the differences between user's expectations and the level of services received determined by the need to improve the service components and to prioritize the elements of a list view of the library. This study assessed the quality of library services based on user's expectations in three levels: minimum, maximum estimated and analyzed.
The study population consisted of 2250 members of the Central Library, Science and Culture, including doctoral students, graduate students, undergraduate students, faculty and employees. Given the sheer size and distribution of the study population, random stratified sampling was used. The sample of study includes 328 students.
Finding: Our findings indicated that the influence of the level of service received, the Central Library of Science and Culture, with a mean (33/7) is more than the other dimensions. But the library as a place was not able to meet user's needs and their expectations and with a mean (58/3) to have the lowest level of service received. According to user's perspective, information control (07/60%), service work component (21/26%) and the component library as a place (72/13 percent) were the main important component, respectively.
After testing the hypotheses, it was determined that in LibQual components there was a significant relationship between the user's highest and lowest expectations and the level service received. Also there was a significant difference among perspectives of doctoral students, graduate students, undergraduate students, faculty and employees in the lowest expectations", "the highest expectations" and "received services". Finally, the results obtained in the field and to improve the level of service quality in academic libraries, solutions and recommendations are presented.
