Platform thinking specialized libraries are no longer just a place to exchange resources and information. They are a center where human interactions create value, and researchers, faculty members, librarians, and managers are the main treasures of these centers, who will exchange the produced values with their awareness and knowledge. To carry out this research, the work steps were defined in two steps. In the first stage, by using the document study method, related documents were analyzed and the criteria related to platform libraries were identified. In the second step, using the Delphi technique, the necessity of implementing a platform library in specialized libraries was evaluated. According to the conducted surveys, the need to change the approach of specialized libraries from traditional to a platform will cause the development and effectiveness of their services. In a specialized platform library, the library is assumed to be a multi-faceted platform that, under the pretext of its services and products, creates a network among stakeholders, including managers, employees, experts, researchers, faculty members, and users. Therefore, addressing an aspect of specialized library services in a new context is of special importance that has not been addressed so far.

Metaverse is a 3D and all-digital world through which users can create their own digital avatars. Metaverse technology is closely related to and uses Virtual Reality(VR), Augmented Reality(AR), Mixed Reality(MR) and Artificial Intelligence(AI) technologies. The applications of Metaverse in veterinary medicine and animal husbandry include: virtual visit of animals by a veterinarian, veterinary education, veterinary surgery, communication with other cooperating veterinarians for help or consultation during surgery, animal feeding and lactation, familiarization with the anatomy of the animal body, use From 3D images to measure animal health and animal disease, facilitate finding veins, more accurate diagnosis, understanding animal emotions and behavior, and evaluating emotional states in animals. Among the benefits of Metaverse, we can mention innovation in health care, facilitating the interaction of information, facilitating disease diagnosis, the feeling of being in the real environment, and ease of storing and retrieving disease information. Among the disadvantages of metaverse, we can point out that it requires advanced digital technologies, high cost, strict control, instability and demeaning. Over time, the problems and disadvantages of Metaverse will decrease and its use will expand in various fields of livestock and veterinary medicine.

The article purpose is to identify the actors and stakeholders of a knowledge-based education system in the field of agriculture and also to explain their convergence in the context of a conceptual network model in order to establish a knowledge-based education system in the agriculture sector of Iran based on the fundamental principles of knowledge management. The findings of the literature review show that the theoretical and operational plans of knowledge management in the field of agricultural education and extension have not addressed the stakeholders of a knowledge-based system and the way of communication between them. This descriptive-analytical research based on a practical point of view explains the method of the identification and networking between actors and stakeholders of a knowledge-based educational system based on the concepts of knowledge management. In the sense that the results of this research can be used in the creation of knowledge management systems in the education sector in the field of agriculture. The fundamental achievement of this study is to present a conceptual model in networking actors and stakeholders in their convergence to create the flow of data, information and knowledge between content producers and consumers in an educational system based on knowledge management.

Intelligent systems in their fields focus on interaction with users and changes and dynamics of social and physical environments. Today's smart systems and robots are independent equipment that can understand their surroundings and pursue specific goals. Despite the fact that this technology is still in its infancy, it has yielded significant results such as fundamental applications related to the new concept of precision agriculture. Several developments have contributed to the emergence and then growth in the field of intelligent agricultural devices, including: the rapid increase in computing power in recent years (in terms of speed and storage capacity), the emergence of electronic components and rich sets of sensors, most of which are relatively inexpensive, and the spread of global positioning systems such as GPS. Although in our country, due to the special conditions of agriculture, such as the small size of the land and the weak economic power of farmers,but in order to use from the many benefits of smart agricultural mechanization and increase optimal production with minimal losses, the familiarity of agricultural managers and operators with these intelligent systems and the sciences related to them should be included in the development-application programs of agricultural research institutes.

In this project, 931, 932 and 933 hybrid cottonseeds were used. ‎This project was carried out on an area of 30 hectares. NDVI index is always helpful in assessing ‎plant health on farm. The most important reason for this capability is that the changes in this index ‎are consistent with the physiology of the plant and in simple terms with the changes in pigments and ‎staygreen of the plant cover. According to the trend of changes in NDVI index, hybrid cotton 933 ‎had the best greenness during the growing period. The variety 933 is the oldest figure in this study. ‎On the other hand, 931, which has the lowest NDVI, is the earliest figure. As the results show, the ‎yield of cotton transplanting was significantly differences by cotton seed planting method. ‎Transplanting yield is more than twice that of cottonseeds in November, especially for cultivar 931. ‎As expected, the highest yield was observed in transplanting 931 and the lowest yield was taken in ‎‎933 seed treatment. With help of NDVI index in September, it is possible to comment on the early ‎maturity of cotton cultivars.‎

This article is about the importance of intellectual property in knowledge-based development and the most important reasons for Iran's membership in international treaties related to intellectual property and copyright. The views of possible opponents of membership in these conventions and negligence in the implementation of national laws have also been analyzed.Among the important questions is whether the hypothetical and claimed "interests or benefits" of the opponents are based on the legal, human, religious, and universal "rights" of consumers or producers of information or not? Are there better solutions to protect the "interests or benefits" and "rights" of all people and society as much as possible?In this article, it was argued that the continuation of the current policies of the government in the field of intellectual property is in conflict with human rights at the national and global level; It is also illegitimate and against religious documents; It is in conflict with reason and logic; It is in conflict with the interests/ benefits of people in Iran; And it is contrary to national and global experiences. It is also against the interests/ benefits of information consumers. It was also argued that the interaction and simultaneity of some technical and social changes, especially in the information, communication and publishing industry, has caused disruption in the national market of production and consumption of knowledge and non-knowledge goods and services under the pretext of Iran's non-membership in these treaties; and the whole society will face big challenges
