plagiarism is one of the new phenomena in the academic environment in Iran, which includes different dimensions and types. So, its recognition and rooting are the problems of this research. Therefore, the main goal of the current research is to investigate the context and institutional and individual factors affecting the formation of plagiarism in Iran and provide policy solutions by decision-makers.

The current research method is descriptive qualitative. The statistical population of the research includes 15 university experts who were selected by judgment and snowball method. The data collection tool is a researcher-made questionnaire, which was completed during three stages (in a round-trip way) of indexing using the Delphi technique, and the validation of the conceptual model of the research was done using experts' opinions.

The findings of the research showed that the factors affecting the occurrence of plagiarism in universities in Iran include two categories of individual and systemic components and 21 indicators related to these components. Individual factors related to the inherent personality characteristics of students such as lack of ideas, inability to manage time, lack of guilt, lack of some skills, and also some deficiencies in professors such as insufficient knowledge, lack of motivation among students, etc. Systemic or institutional factors are mostly due to incomplete and insufficient laws of universities, inappropriate training of these centers, and lack of attention to plagiarism and plagiarism.

In the end, based on both individual and systemic effective components, practical solutions have been presented to deal with plagiarism in universities.

Errors in data collection and failure to pay attention to data that is noisy in the collection process for any reason cause problems in data-based analysis and, as a result, wrong decision-making. Therefore, solving the problem of missing or noisy data before processing and analysis is of vital importance in analytical systems. The purpose of this paper is to provide a method to identify noisy data, outliers, and missing data and provide a suitable solution for these data.

This study is applied research. Data mining techniques including binning smoothing and regression models have been used to identify and replace outlier and noisy data.

The results of the tests performed in the real environment related to the data of social networks show the proper performance of the proposed method. It has also been shown that the proposed method has higher accuracy compared to the methods of binning smoothing, average and linear regression. So that for the data related to the tweet section, the mean squared error obtained for the proposed method was equal to 0.04, the binning smoothing method was equal to 0.38, the linear regression method was equal to 0.05 and the average method was equal to 0.06.

The method presented in this article can initially identify outlier data through one-third and two-thirds normal, and then replace the outlier data with a linear regression model, which results in improving the performance of using and processing information and improving human-information interaction

The present study was conducted by explaining the internal norm of Davis's technology acceptance model in online health information search among Iranian students to provide a local model.

The current research is descriptive and was carried out using a survey method. The research community is the students of Ahvaz Jundishapur University of Medical Sciences at all levels of study. A sample of 358 people voluntarily participated in the research by stratified random sampling. The research tool was a researcher-made questionnaire with 20 questions, which after validation, Cronbach's alpha was 0/933 Obtained. The findings were analyzed with SPSS and AMOS software and using descriptive statistical tests, exploratory factor analysis, and other related tests.

The findings of the exploratory factor analysis led to a four-factor model regarding students' online search for health information. The first factor: is the user's intention to search for health information online, the second factor: is the usefulness of using the Internet to receive health information, the third factor: is the ease of using the Internet to receive health information, and the fourth factor is the user's attitude towards the online search for health information. These four factors explain 66.983% of the changes related to the online search of health information among students.

The findings of the research indicate the approval of the Davis technology acceptance model for use in research in the field of health information among Iranian students. Therefore, it can be used in other research in this field among students with the assurance of confirming the internal norm.

Information literacy is the ability to identify and critically evaluate information to solve problems in a specific field. The use of this procedure in the environment of universities and for students depends on their awareness of the many angles of information measurement in this field.

this study was to investigate the information literacy status of students and teachers of the Farhangian University of Kurdistan Province From six perspectives: information review, information source recognition, information dissemination, information recognition, flexibility, and information search. This research is practical and of a survey type and was carried out between January and March 2022. The study population consisted of all students of Farhangian University of Kurdistan Province in the academic year 2021-2022, which numbered over 1500 people. Using random sampling, 350 student-teachers were selected as a statistical sample. The data collection tool was a researcher-made 66-item information literacy questionnaire based on a 3-point Likert scale. The reliability of the questionnaire was 86% using Cronbach's alpha method. And for its validity, the views of university professors were used. Multivariate analysis of variance, one-way analysis of variance, and Pearson torque correlation coefficient test was used to analyze the data using SPSS software.

The results showed that there is a significant relationship between the components of information literacy of male and female student teachers (P = 0.0001). Therefore, in this study, gender has a small effect on the components of information literacy. Also, there is no significant difference between information literacy in its 6 components and the different educational disciplines of Farhangian University (P> 0.05). Finally, there is no significant relationship between information literacy in its 6 components and the age of Farhangian University students and teachers. Therefore, the information literacy situation of the students of the Farhangian University of Kurdistan is at an Intermediate level.

Information literacy is the set of skills and qualifications needed in the information society for teachers, therefore, by considering factors such as review, knowledge of sources, dissemination, recognition, flexibility, and search for information, it can be enriched. Building information literacy skills.

As mission-oriented organizations, research institutes have the task of answering community questions in specialized areas, and should therefore be able to effectively present their outputs to their target users. Achieving such a goal requires the proper use of information architecture principles to properly organize the information platform in which the research institutes interact with their audiences. Therefore, reviewing and evaluating the information architecture of Research Institutes’ websites as their main communication platform with their users is of particular importance. The purpose of this study is to evaluate the Iranian Research Institute for Information Science and Technology’s website based on information architecture.

The research method is based on content analysis and case evaluation and is done using direct observations and checklists in March 2022. In this regard, first the components of the information environment, ie the context, content, and user of the website are identified. Then, we check the information architecture subsystems of the website using checklists based on the components of the information environment. The organization system checklist contains 14 main questions, the labeling system checklist contains 32 main questions, the navigation system checklist contains 20 main questions, and finally, the search system checklist contains 41 main questions. The checklists were prepared using the library research method and approved by an expert panel. Excel software is used to collect and analyze data.

Users of the Iranian Research Institute for Information Science and Technology’s website can be categorized into four groups: researchers and students, science and technology policymakers, librarians and informants, and educational and research institutions. The main content of this website includes reports, books, articles, research projects, information systems, scientific events, training courses, laboratories, and collaborative services. The context of the website is based on service development and delivery in the areas of knowledge management, scientific and technological information management, dissemination of information science and technology, supporting science and technology policymakers, Publicizing the use of information technology, cooperating with universities and research institutes, and supporting research in the field of information science and technology. The results of the checklists indicate the score of this website for the organization system, the labeling system, the navigation system, and the search system as 67.6%, 68.4%, 65.4%, and 34.8%, respectively.

The status of the Iranian Research Institute for Information Science and Technology’s website is assessed as good in terms of the organization system, the labeling system, and the navigation system, and poor in terms of the search system. The use of an audience-oriented organization plan in the website organization system, the use of index labels in the form of unique entities in the website labeling system, and the use of a main navigation bar with an integrated and similar design in the website navigation system are among the strengths of the website information architecture design. On the other hand, according to the research findings, to improve the search system, it is necessary to pay attention to features such as “correcting spelling errors in the input query”, “highlighting the input query in the retrieved results”, “adding logical operators to the search system”, “searching metadata”, “sorting results in alphabetical and chronological order”, and “adding search filters such as subject and year”.

A thorough understanding of the drivers and inhabitants to the study can provide the basis for effective planning to improve the study. The aim of this study was to investigate the driving and inhibitory factors affecting the tendency of Iranian knowledge and information science PhD students towards study.

This research was conducted with a qualitative approach and using content analysis method. The data collection tool was an in-depth semi-structured interview. The interviews were conducted through face-to-face visits, telephone calls, e-mails, sending and receiving audio files and conversations on social media. PhD students in knowledge and information science at state universities, Payame-Nour Universities, and Islamic Azad Universities form the research community, and 33 people were selected as the research sample using targeted sampling.

The results show that four factors of "professor", "compulsion", "personal promotion" and "interest" were the driving factors among doctoral students and seven factors were "professor", "family". "Access problems", "ambiguous future", "problems and weaknesses of the educational system", "growth of the spirit of need to study" and "non-participation in teaching" have been identified as deterrents factors.

The drivers and inhabitants of the study are very intertwined and interrelated. Some of these factors affect others and are in some way the cause and effect of each other. To strengthen effective factors and reduce barriers to study, it requires more effort from professors and programmers at the macro level, libraries and librarians, politicians, and more effort and planning from doctoral students themselves. It is necessary for the education system and the education system in universities to get out of the monolithic system and to be the speaker of unity. In this way, students are less likely to study and research until there are fundamental changes in teaching methods and curriculum content in the education system. For the first time, this study examines the most important factors and barriers to the advancement of PhD students in information science, and the results provide qualitative factors for the context of the research community. And it can be used in planning and policy making for the doctoral program of the field. Since no research has been done in this field so far, the present study can be considered as a new research in this field.
