Abstract
Background and Aim: Image, as a kind of information vehicle which can convey a large volume of information, is important especially in medicine field. Existence of different attributes of image features and various search algorithms in medical image retrieval systems and lack of an authority to evaluate the quality of retrieval systems, make a systematic review in medical image retrieval systems field necessary. The objective of this study was to conduct a systematic review of papers on medical image retrieval systems appeared between 2000 and 2011.
Method: The major scientific databases (Medline, Scopus, Webof Knowledge (ISI), and Google Scholar) were searched, using standard keywords in English between 2000 and 2011. All papers reviewed using standard critical assessment and grading and papers with more than half of the quality scores were considered as qualified to enter to the next stage. Then, the data in selected studies were extracted and classified.
Results: Eighty sixreviewed papers were classified into 3 categories. The first category introduced new medical image retrieval systems (40%) and the second category presented a new framework for the major medical image retrieval systems (45%) and the last category was about medical image retrieval systems evaluation (15%). However, the growth rate was increasing during the period and the most papers published in 2009. The CBIR systems were used more (66%) and then hybrid systems (20%) respectively.
Conclusion: Applying medical image retrieval systems with Decision Support Systems (DSS) and other information and computer technologies can help clinicians to present a better service and can help them in diagnosis as well. Meanwhile, these systems can be very useful in education and research, the medical image retrieval systems can be more successful if they are designed for a specific field and based on new and modern image features.

Methodology: This is an applied study in terms of purpose and in terms of method is qualitative research that have been done by systematic review method. For this purpose, articles have been obtained by searching databases of Springer, Emerald, ProQuest, Web of Science, Google Scholar, Science Direct, and Semantic Scholar.
Articles published between 2000 and 2021 have been scrutinized. The systematic review model of Kitchenham and Charter (2007) was surveyed. According to the inclusion criteria, 1296 articles have been extracted after initial refinement, and among them, 77 articles related to the subject have been identified by reviewing the titles of articles and entered the final review by reviewing the full text. In conclusion, 29 articles were chosen for final analysis. The Qualitative content- coding method was used for data analysis and qualitative analysis was performed by two coders. The agreement of the evaluators based on the formula of Miles and Haberman for the performed analyzes, 78.5 was obtained.
Findings: Based on the results of qualitative analysis, 74 basic, 13 organizing and 3 comprehensive themes of "digital services,” “digital library management" and "digital collection" have been identified, which in total define the application of data mining in digital libraries represented.
Conclusion: Using data mining techniques in digital libraries, a variety of information can be stored seamlessly in different classes so that the end user of the information could meet their information needs in the shortest possible time. On the other hand, libraries can provide more useful resources by analyzing their users' information interests, and this can be considered a turning point in situations where libraries are facing financial difficulties.

Abstract
Introduction
This study aimed to investigate and quantify the results of studies examining the relationship between leadership styles of managers and employee burnout. Burnout is a job-related phenomenon that can lead to mental disorders such as depression and an increased risk of suicide. It negatively impacts various professions and organizations, particularly in the social services and healthcare sectors. Managers' leadership styles play a crucial role in either reducing or increasing employee burnout.
Methods and Materoal
The research was conducted through a systematic review and meta-analysis, following the PRISMA guidelines. Studies related to leadership styles and burnout from 2000 to 2024 were reviewed.
To identify relevant studies, national and international databases were searched using related keywords. Nineteen selected studies, examining the relationship between various leadership styles (transformational, transactional, ethical, and spiritual) and burnout, were analyzed. The studies were conducted in different Iranian cities, including Khorramabad, Gilan, Tehran, Sanandaj, and Shiraz, with sample sizes ranging from 87 to 369 participants. The methodologies used included descriptive-correlational analysis and structural equation modeling, with common tools being leadership style questionnaires and the Maslach Burnout Inventory.
Resultss and Discussion
The meta-analysis findings revealed a moderate, significant negative relationship between managers' leadership styles and employee burnout (g = -0.35; 95% CI [-0.42, -0.28]). However, Galbraith and funnel plots indicated relatively high heterogeneity and publication bias in some studies. The meta-regression showed that sample size explained 16.17% of the heterogeneity between studies, while publication year and research location were not significant. Additionally, the cumulative plot demonstrated fluctuations in results over time, indicating a lack of stability. These findings suggest the need for more research to achieve stable and accurate conclusions.
Conclusion
The discussion and conclusion section highlights the importance of examining the relationship between leadership styles and burnout, given the prevalence of burnout and its negative effects on employee productivity and mental health. Evidence suggests that inappropriate leadership styles can lead to burnout. Managers with suitable leadership styles can prevent reduced performance and employee motivation. However, due to the heterogeneity of studies and methodological limitations, caution should be exercised when generalizing the results. Future research should use standardized scales, advanced statistical methods, and larger random samples to ensure more reliable outcomes.

Introduction
Blockchain technology was first introduced in 2008 as a peer-to-peer electronic payment system. This technology has since attracted widespread attention in the field of scientific research as well as industry. Blockchain has been examined from various aspects. For example, a body of research examines how blockchain's decentralized approach could completely disrupt current business models, financial systems, organizations, and civil governance. Arguably, the clearest evidence of the growth and pervasiveness of this technology is the combined blockchain market capitalization reaching more than 2.6 trillion cryptocurrencies in 2024. In addition, development activity has been steadily growing over the past decade, and numerous projects have been launched to improve the core design of the blockchain (Bitcoin) (such as Ethereum, Kava, and Solana blockchains, etc.). Several articles have systematically reviewed the studies conducted in the field of blockchain in the country using the meta-combination method, all of which focus on the review of foreign articles. Due to the growth and widespread use of blockchain technology in the country and the increase in the scope of domestic research related to it, a systematic review of the research conducted inside the country also seemed necessary. In this regard, the aim of this article is to systematically review internal articles in the blockchain field, focusing on the human-computer interaction (HCI) field of study.
Methods and Materoal
In this research, we have used the qualitative meta-method for a systematic review of blockchain research. A systematic review is a method of identifying, evaluating, and interpreting past research related to a research question, topic area, or phenomenon of interest. The focus of this review is to summarize the HCI literature on blockchain technology. We organized this literature review in four comprehensive steps, following the PRISMA systematic review protocol.
Resultss and Discussion
We found that the articles in our sample adopted one of the following two perspectives. They conducted their research either on blockchain technology (74 articles, 66%) or specifically on cryptocurrencies (37 articles, 34%). Articles related to blockchain technology mainly discuss the understanding of users' motivation, perceived risks and the application of this technology, and articles related to cryptocurrencies also deal more with the jurisprudential and legal aspects of cryptocurrencies and the analysis of transaction risks and user experience. Most empirical studies that deal with people evolve around cryptocurrency, while contributions to blockchain often lead to products or evaluations of financial and administrative systems.
After providing an overview of blockchain research in the HCI community, we present and discuss the salient themes that emerged from the literature review. We identified 4 main themes:

After providing an overview of blockchain research in the HCI community, we present and discuss the salient themes that emerged from the literature review. We identified 4 main themes:
- Decentralized economy and smart contracts (13 articles, 12%)
- Users' understanding and participation of blockchain technology and cryptocurrencies (48 articles, 43%)
- Application of blockchain technology in a specific field (34 articles, 31%)
- Jurisprudence and legal issues around blockchain and cryptocurrencies (16 articles, 14%).
Conclusion
After completing the systematic review of domestic articles, the most interesting point for us is the difference between domestic articles and international topics. As mentioned in some parts of the article, there are three general interests in the international research space that are less observed in domestic research. The first is issues related to the concept of trust in blockchain technologies. The second is the issues related to technical infrastructure and generally the way of socio-technical interactions in society, and the third is related to blockchain-based micro-projects such as Ethereum, Kava, Solana, etc., which are not considered in Iran.
The blockchain ecosystem has experienced rapid growth over the past decade. While until recently, Ethereum was the only widely used blockchain platform supporting decentralized applications, today several new blockchains (such as Solana, Kava, Polkadot, Terra, etc.) have been launched for decentralized applications. Many believe that this new generation of blockchains, which now offer instant transactions with low transaction fees, promises the third generation of the web. Web 1.0 allowed users to read (consume) content on the Internet. Web 2.0 added authoring options and the ability to generate content, thereby enabling rich interactive Internet applications. Powered by blockchain, Web 3.0 now adds the ability to own, create, and distribute digital assets. The first signs of this paradigm shift are the emergence of decentralized finance (DeFi) and non-fungible tokens (NFT), which so far account for more than two-thirds of transactions on the Ethereum blockchain and are driving user adoption of Ethereum. These topics and developments are being noticed by researchers all over the world, but we did not find any study in these fields inside the country. This issue is particularly important from the aspect that Web 3.0 challenges human interaction and cooperation on the Internet and, in a sense, mixes the human and technological space together.The need to pay attention to these research fields as well as the acceptance of interdisciplinary studies (specifically socio-technical studies) should be taken into account in order to open a gate for understanding the fast-paced global technological developments in the space of social studies and a field for presenting theories. To provide a new society in accordance with the socio-cultural context of Iranian society.
