Today, organizations use modern tools and methods to identify problems, find appropriate solutions, and make fundamental decisions, and this is the distinguishing feature of organizations and their promotion. The category of knowledge management is one of these solutions. This research first examines the concepts and capabilities of knowledge management, then the enablers of knowledge management, which include organizational culture, information technology, organizational structure, and human resources, are examined. In the following, the steps of the organizational knowledge management process are presented and the way of influencing this process on the organizational performance is investigated. The obtained results indicate that organizations should carry out a knowledge needs assessment with the participation of managers, experts and elites of different fields, and based on them, determine the knowledge goals of the organization and formulate appropriate strategies to achieve the goals and also improve the organizational performance. At the end, suggestions are made for improving performance and achieving goals for organizations.

This article aims to present a new method of knowledge retrieval through an intelligent interactive system using the Fibonacci classical sequence in developing a knowledge management system. An intelligent interactive system is necessary for retrieving practical information related to user questions. This interactive system can be designed by relying on a computer program (software agent, or bot) to simulate an intelligent conversation. Bots are used as intelligent virtual assistants to simulate conversations in exchanging information and knowledge. The way to develop chatbots is to use Frequently Asked Questions (FAQ) to record questions and answers. This interactive virtual assistant between man and machine can achieve stable and acceptable intelligence in answering questions through innovative methods such as using the Fibonacci sequence. Such algorithms are specifically designed to predict the user's expected question from the database or information with the least complexity and matching the user's needs. Such knowledge-based systems can be used in specialized organizations such as Agricultural Research, Education and Extension Organizations in order to exchange information and knowledge for their employees and users. In addition, the creation of intelligent interactive systems can play an important role in providing appropriate answers to farmers' questions in agricultural sector of Iran.

Precision agriculture is an agricultural management strategy that aims to increase productivity and optimize production by collecting, processing and evaluating data. Achieving the highest profit is the main goal of production for the farmer, using accurate data and analysis can provide more yield and subsequently more profit. The main goal of precision agriculture is to achieve sustainable agriculture through reducing the use of chemical fertilizers and as a result reducing environmental pollution. The tools used to collect data in this technique include remote sensing with satellites, the use of drones, sensors, and robotics. Despite many advantages, the application of this type of agriculture has not yet received attention in Iran. Although the infrastructure of using this method in Iran is somewhat available; But the low level of farmers' knowledge and the small farms are two main problems in precision agriculture, so investment in it is slow. Increasing the farmers’ knowledge, merging agricultural lands and encouraging investment in agriculture are three important solutions in the transition from traditional agriculture to modern agriculture. In this article, an attempt has been made to pay more attention to the precision agriculture and introducing it as possible to the farmers and users.

Accurate determination of land boundaries is a vital step in identifying land use and planning for its management. For cropland, this mapping allows farmers and agribusinesses to better estimate land area for effective use of agricultural inputs, such as seeds, pesticides, fertilizers and other resources, and to optimize production and post-production activities. With these interpretations, identifying the precise edges of a crop field determines the success of a program developed using computer vision and machine vision tools. According to the experiments, the Canny detector performs better than other traditional detectors, therefore, in this article, it has been tried to present new methods to improve the performance of the Canny detector by using two meta-heuristic algorithms of ant colony and thermal simulator. To evaluate the proposed methods, we have used three evaluation criteria: MSE, PSNR, and SSIM. The results show that the meta-heuristic algorithms used have made the Canny detector more optimal. When we used the ant colony algorithm, the edges were shown well, and when we used the simulated annealing algorithm, in addition to the edges, the image texture was also preserved.

The purpose of this research is to investigate the current status of articles of Iranian universities and institutions in the field of vaccine in the ISI Web of Science international citation database based on quantitative and qualitative scientometric indicators.

In this study, scientometric methods and citation analysis were used.

The findings of the research show that 1781 articles with at least one author's organizational affiliation related to Iranian universities and institutions are indexed in this database. Razi Vaccine and Serum Research Institute is the most cited with an average of 12.88 citations per article and also has the lowest author self-citation among universities and institutions with 2.5%. Iranian writers had the most co-authorship and international collaboration with their counterparts from the United States, Germany and England, respectively.

Because most Iranian articles are published in Q3 and Q4 journals with a low impact factor, the average citation of Iranian articles in the field of vaccine is much lower than the global average and the average of other countries. In terms of co-authoring and international collaboration, Iranian researchers, same as other countries, have collaborated the most with their counterparts from America, Germany, England and Canada.

Information concealment is one of the most important reasons for the occurrence of incorrect economic, social, political and cultural phenomena in Iran. Its opposite is information transparency or free access to information, which is an efficient mechanism to reduce some anomalies. Both secrecy and transparency depend on the quality of access to information.The best mechanisms to reduce errors and increase the use of successful experiences are the organization of government records, and access to information. The quality of decision-making depends on information.The approval of the bill on information transparency and free access to government information by Iran’s Parliament can be considered as a reaction to reduce economic, political, social and cultural anomalies, as well as emphasizing development based on transparency and justice.I am going to introduce government/ public documents and some mechanisms to organize information and make them accessible; Depository library and information center and its goals and duties according to “the Law of Publication and Free Access to information” is another topic. It is recommended that the task of depository, information organization and services related to this law should be included in the executive regulations and the goals and duties of all libraries in Iran.
