ABSTRACT Over the past 50 years since the first research in the field of urban Development implementation plans, there has been a noticeable absence of a comprehensive literature review on this topic in the global arena. This article provides a textual analysis related to the subject of urban Development implementation plans, to identify important and recurring themes alongside analyzing the relationships between authors, journals, and countries in this field. Along with the bibliographic analysis, documents related to the field of urban Development implementation plans were reviewed to identify influential indicators in their implementation. To this end, 456 scientific articles were extracted from the Scopus scientific database as of October 28th, 2022, and analyzed using scientometric software. These analyses include examining author keywords, country co-authorships, journal bibliographic coupling, and author co-citations. In this study, 74 final indicators were identified as the most recurrent indicators in this field. The bibliographic analysis also produced several noteworthy results. The United States is the most active country in this field, with a link strength of 40 and 176 articles. Berke, P. is the most influential author in this field, with a link strength of 1623 and 99 citations. Among the journals examined, "Land Use Policy" has the highest bibliographic coupling strength of 84, and the "Journal of the American Planning Association" has the highest number of documents related to this field, with 22 documents; finally, among the identified. Extended Abstract Introduction The implementation of urban Development Projects has been a neglected topic in public policy research, despite its critical importance in ensuring the success of such Projects. While there have been numerous studies on the factors that contribute to the success or failure of policy implementation, there has been a lack of systematic reviews on the subject of implementation as a whole. This study aims to address this gap in knowledge by providing a comprehensive overview of the implementation process of urban Development Projects. This study aims to address this gap in knowledge by providing a comprehensive overview of the implementation process of urban Development Projects. The study begins by collecting and categorizing existing research in the field, focusing on three main questions: -What are the key indicators for successful implementation? -What are urban journals and articles' current trends and performance? -How do countries and researchers collaborate in this area? The study also examines the relationships between authors, publishers, and different types of documents through bibliographic analysis. Ultimately, this study highlights the need for further research and a more structured approach to understanding the implementation process of urban Development Projects.   Methodology This study examined the literature related to implementation and evaluation plans in urban and land use planning. The authors used the Scopus database to extract and collect data, focusing on combining the keywords "implementation-plan" and "evaluation-plan" in the keywords, abstracts, and titles. Initially, 621 studies were extracted, but 456 articles were selected as the final database after filtering out non-article documents. The authors observed a general upward trend for studies from 1968 to 2022, with a significant increase in the slope of the trend from 2007. However, a slight decrease in studies was observed in 2021 and 2022, possibly due to the global pandemic and the emergence of new related topics. The authors used a four-stage process to analyze the bibliographic subject of the study, including simultaneous occurrence analysis, co-authorship analysis, bibliographic coupling analysis, co-citation analysis, content analysis, and thematic analysis. The authors identified the selected articles' research objectives, methodologies, findings, and main themes and sub-themes. Overall, this study provides a comprehensive analysis of the literature on implementation and evaluation plans in urban and land use planning.   Results and discussion This research aims to comprehensively analyze the implementation and execution of urban Development plans using bibliometrics and systematic analysis. The study considers evaluation as a crucial part of the implementation process and seeks to answer three fundamental questions. Firstly, it identifies effective indicators of implementation and execution globally. Secondly, it examines the trends and performances of new articles and urban journals. Thirdly, it investigates the pattern of cooperation among countries and researchers. The study identifies 74 general indicators that significantly impact the implementation process of urban plans. The results show that "performance evaluation," "effectiveness," "land use," "zonation," "participation," "program quality," and "implementation program" are critical indicators in this area. The study also highlights the importance of evaluation in the discussion of program implementation and its separability from the implementation process. Using the scientometric software VOSviewer, the study analyzed 68 keywords related to the bibliographic topic. "Program evaluation" obtained the first place, followed by "Program implementation" and "Program quality." The co-authorship analysis based on author items revealed that Berke, P. has the highest number of citations and link strength. Additionally, the study found that 72 countries have research in this field, with 22 countries having at least 5 citations that were clustered into 5 clusters by the software. The "land use policy" journal had the highest link strength, and the "Journal of the American planning association" had the highest number of documents related to this field. In conclusion, the study provides valuable insights for policymakers and researchers interested in urban Development planning. It comprehensively examines the implementation and execution of urban Development plans, identifies effective indicators, and investigates the pattern of cooperation among countries and researchers. The study highlights the importance of evaluation in the implementation process and its separability from the implementation process.   Conclusion The main goal of this research was to fill the gap in research on the implementation and execution of urban Development Projects in the field, as no systematic review of the topic has been conducted from a global perspective since the first research in this field about half a century ago. Only in some studies, such as those by Talen (1996), Oliveira & Pinho (2010), Rudolf & Grădinaru (2017), has the evaluation of implementation been systematically reviewed, or the systematic review of experiences in a specific urban area, such as the review of various experiences in the Beijing urban area (Chu, 2020). In this research, with the comprehensive approach that the evaluation of implementation is an integral part of the overall process of implementing and executing urban Development Projects, this process has been examined from the perspective of bibliometrics and systematic analysis of this field. The main difference of this research, which makes it completely new, is firstly having a comprehensive approach to the implementation field, where program evaluation is only an important part of its structure, and secondly, using the scientometric software VOSviewer for the first time in this field. In essence, the conclusive outcomes of this investigation were entirely novel and exhibited some partial congruences with antecedent studies in the domain of appraising and discerning indicators. Significantly, this research has conferred a systematic appraisal of the literature concerning the urban implementation and execution of Projects, which is an unprecedented contribution. It should be acknowledged that this is an initial survey of data intended to offer a comprehensive outlook on this scholarly field, and thus it is subject to certain limitations, such as its confinement to the Scopus database. As such, it is recommended that future research endeavors encompass an analysis of additional databases and undertake comparative evaluations of the results.

ABSTRACT With the expansion of inefficient tissues, "Urban regeneration" has been objectified as a solution for developing cities in different physical, social and economic dimensions. Despite the Development of the guidelines for urban regeneration Projects, these Projects in Iran still have challenges in the stage of realization and implementation. This article aims to identify the "challenges and causes of non-realization of urban regeneration Projects in Iran" and analyse the research conducted in this field with a qualitative approach. For this purpose, a meta-analysis of 23 articles in the field of problems of urban regeneration Projects in Iran was carried out. The challenges raised in the AtlasTI software were extracted with the help of open and axial coding. In the following, 100 codes were determined in the form of 10 groups or general categories. In the end, the obstacles to the realization of urban regeneration Projects in Iran were given. According to the obtained results, the weak presence of non-governmental organizations, the problems of preparing plans, institutional and management problems, and the weakness of participation are the four most important and frequent challenges in the research related to the realization of urban regeneration Projects in Iran Extended Abstract Introduction The trend of urban population growth and the expansion of inefficient urban fabrics along with the increasing immigrant population to the cities makes the planners think of filling the existing urban fabrics with excessive density and land use change, instead of the city horizontal Development with regard to the urban sustainable Development prism. Poor housing, low per capita services, lack of necessary infrastructure, low quality of life, economic stagnation and functional inefficiency, unorganized physical-spatial structure, high vulnerability to earthquakes, loss of social status, and various social problems exemplify the typical challenges of such deteriorated areas. Deterioration of the urban fabric has prompted the emergence of various urban Development policies among which regeneration as an overarching approach characterized by its economic, social, environmental, physical, ecological dimensions and components including quality of life, justice, revitalization and participation. This concept, as an urban Development policy, has been defined and applied in the vulnerable and deteriorated areas of cities in recent years. Started from physical reDevelopment in the Second World War and passing through policies concentrated on social and economic welfare, urban regeneration policies moved towards the participation of local residents and the creation of sustainable places in recent decades. However, taking into consideration the manifestation challenges of urban Development plans, in the existing literature, urban regeneration challenges have been less comprehensively investigated. This paper aims to identify the "challenges and causes of lack of urban regeneration plans manifestation in Iran" based on the review and analysis of the research conducted in this field with a qualitative approach in response to this question: "What are the challenges and obstacles to the manifestation of urban regeneration Projects in Iran?”   Methodology This research aims to identify "challenges and obstacles to the manifestation of urban regeneration Projects in Iran" through a meta-analysis of the research conducted in this field. Conducting a systematic search in Magiran, comprehensive humanities portal, and Google Scholar databases using the Boolean logic search used the keyword (challenges) AND key phrases (‘manifestation of plans’ AND ‘urban regeneration in Iran’) resulted in more than 70 Persian papers, 2 English papers, and 2 English theses. The reviewed studies included research and review papers, case study research, and the special issue of urban regeneration policy of Haft Shahr Journal. The geographical scope of the investigated studies covers the historical contexts of Iran, and metropolises such as Tehran, Tabriz, Shiraz, and Isfahan. Reviewing the abstracts, 23 studies were selected among which the research focusing on the different types of regeneration, and evaluation of urban regeneration indicators were excluded from the research process. To conduct meta-analysis after a comprehensive review of each study, open and focused coding of challenges was done through Atlas.ti software (version 8), and the obstacles to the manifestation of the plans were extracted. Coding process continued until the saturation was reached. Finally, the 115 codes obtained was reduced to 100 through integrating similar codes. Then, all the codes were categorized into 10 categories, and a comprehensive model of "challenges of manifestation of urban regeneration Projects in Iran" was presented.   Results and discussion Based on the conducted review, the recognized problems with emphasis on the different aspects of urban regeneration Projects are: 1) Weak presence of non-governmental organizations (18 codes); 2) Problems of preparing plans (17 codes); 3) Institutional and managerial problems (14 codes); 4) Weakness of participation (13 codes); 5) Duration and financial problems of urban regeneration plans (10 codes); 6) Problems of urban regeneration plans process (8 codes); 7) loss of identity of fabrics in the preparation of the plan (6 codes); 8) Lack of context-oriented approach (7 codes); 9) inefficient evaluation of plans (4 codes); 10) lack of social and specialized training for citizens and officials (3 codes). The lack of endogenous theory and insufficient knowledge of the environment and residents obstacle the manifestation of urban regeneration plans. Despite pretending the use of non-governmental organizations, the relevant law weaknesses, and the lack of belief in the effectiveness of it has led to disregard of the participation of non-governmental organizations in practice in the process of preparing and implementing Development plans resulting in an inadequate context for manifestation of urban regeneration plans. In addition, the government supervision on NGO’s in the way of achieving independence has also caused limitations for their interplay. In terms of the issues in the preparation of plans, more emphasis on the physical and economic dimensions and the purely physical view, and the lack of attention to the social and cultural consequences, along with the loss of the community identity, are the factors of the failure of the plans to achieve the expected results. The lack of coordination between programs and multiple decision-makers led to the institutional confrontation instead of interaction. In this regard, the necessity of an integrated and comprehensive approach to urban regeneration has been acknowledged in the reviewed studies. NGO’s can play an effective role in communicating with citizens, educating citizens and informing them. It is also necessary to have the participation of the private sector and other organizations involved in the field of urban Development in addition to public participation in all steps of preparation, implementation and occupation of Projects and Development plans. In the absence of a context-oriented approach in the preparation and implementation of urban regeneration plans in Iran with blind imitation of western models and the existence of limited urban infrastructure, following consequences are inevitable: uncertainty in terms of time, cost and site preparation before the implementation of the plan; lack of definition of urban regeneration plans in the different scales, neighborhood, region and city; and the uncertainty of the relationship between these plans and other urban Development plans. As such in the current inadequate conditions driving the process of preparing plans, the possibility of implementing new policies and plans, is low and the implemented plans like many other urban Development plans in Iran, are inefficient in the absence of the post occupancy evaluation.   Conclusion Based on the results, four priority challenges in the manifestation of urban regeneration plans in Iran include; the weak presence of non-governmental organizations, the problems of preparing plans, institutional and managerial issues, and the weakness of participation. "The weak presence of non-governmental organizations" has been mentioned as the first challenge in most reviewed studies (Ahmadifar et al., 2014). Regarding the "participation of citizens" even though in the set of laws and regulations of sustainable urban regeneration, promotion of citizenship culture, participation, and cooperation of local institutions are highlighted, the residents are not welcomed in practice. On the other hand, the lack of people's participation in the preparation and implementation of plans has made any urban regeneration actions fail or achieve to its partial goals. In this regard, the results of the previous comparative comparisons have shown that the lack of laws and regulations supporting participation in various fields is of the key factors (Nourian and Ariana, 2011, Shafie Dastjerdi and Sadeghi, 2016). The problems of preparing plans, institutional and managerial issues, ranked as the third and fourth issues in this study, have been emphasized in previous studies as well (Kalantari Khalil Abad et al., Pakro and Sattarzadeh, 2014, Izadi et al., 2019). Therefore, prioritizing the challenges raised by experts and determining operational strategies to solve them are issues that can be addressed in future studies.   Keywords Urban regeneration plans, manifestation, meta-analysis   Funding There is no funding support.   Authors’ Contribution All of the authors approved the content of the manuscript and agreed on all aspects of the work.   Conflict of Interest Authors declared no conflict of interest.

There is increasing demand for sophisticated software engineering processes in today's software systems. In this regard, however, there is a multitude of different processes and each has various advantages and disadvantages some of which relate to the problem domain or in the context of Development. Computer software Development processes have to pass through many scenarios to be completed. There are many ways to solve a single problem in software Development. Sometimes, in structural engineering, the developer is not able to decide which process will suit a particular problem. It can be said that selecting a suitable process is a big issue in structural process software engineering, and the problem of selecting a good candidate method is a big issue in structural process engineering. The solution of such kinds of problem can be found in the work to be done and the task to be performed by the operational process rather than by the process structure. This paper introduces the notion of process operationality and proposes ' process architecture' to represent this operationality. Thus, Structural Process Engineering (SPE) becomes Operational Process Engineering (OPE). Operationally close process architecture is selected, adapted, enhanced, and restricted as needed. The task of construction consists of putting together process features and structuring the new process.

The increasing trend of destruction of natural resources, soil erosion and the occurrence of destructive floods in the country, despite extensive watershed management measures during the past four decades, has increased the need to evaluate the effects of these plans and access statistics and information during the exploitation period. The present research has evaluated the effects of watershed management Projects on eight global Development indicators in the Natanz Urban, Hunejan Shahreza, Qale Qadam Semirom and Sibak Fereidounshahr watersheds. In this regard, after examining previous sources and researches, regarding the collection of information on watershed management plans and natural resources at the level of the mentioned watersheds in the period before and after implementation during the 20-year period from 1375 to 1395 in the form of questionnaires, face-to-face interviews, gathering information from relevant organizations and using satellite images, aerial photos and detailed reports of each watershed have been done; The results of the survey have shown that the implementation of watershed management Projects in general has a positive effect on global Development indicators and has increased the level of these indicators in such a way that these mechanisms have improved.

According to forecasts, the peak of Iran’, s electricity demand will reach at least 100, 000 MW in the next 10 years, while due to insufficient Development of power plant capacity, the maximum electricity demand of 60, 000 MW could be met in Iran annually. Lack of proper financing methods for power plant Development Projects was the main reason in this regard. In the present study, by evaluating the current method of financing power plant capacity Development and examining common tools and methods of financing power generation Projects in the world and according to Iran’, s economic conditions, the institution(s) providing financial resources as well as the needs and goals of the country’, s electricity industry, using crowd-funding method in the form of Energy Production and Efficiency Fund for the financing of Projects related to these two areas in Iran has been proposed. The results showed that the model presented in this paper, while maintaining the income from capital assets of the electricity industry and preventing the capital flight from the industry, would reduce the susceptibility of power plant Development Projects to national currency devaluation and thus reduce electricity supply costs for final subscribers. Based on the results, transition from the current financing model to the crowd-funding model aiming to separating capital costs from operating costs and maintaining financial resources from capital revenues of power plant Projects is proposed as one of the main policies of the electricity industry.

Following the extension in research area and difficulty in different phenomena's research, new necessity in research is generated. So, in each project of research has used different methods. Mixed method has granted opportunity to researchers to mix different dates and results in scientific framework that exploited of different methods (qualitative and quantitative methods). In this way, researchers can access the best solution for different problems and recognizing them. In this article, three movement of methodology (qualitative and quantitative and mixed methods) are mentioned and is studied the advantages of mixed method in small scale Projects. For example, rural Development Projects, specially rural tourism.
