Abstract
The purpose of this research is to analysis the attention to the audience in interdisciplinary studies in the field of children’s literature and suggest criteria for future research. In order to achieve this goal, the position of the audience has been described and analyzed in the structural elements of the research, including: purpose, components, method, and sample. Using Synthesis Research, 38 interdisciplinary research papers, including scientific articles and senior and doctoral dissertations, were selected and then their research structural elements were extracted and analyzed in descriptive tables. Based on the findings, three main goals were considered in these studies: Frequency, Representation, and Component Comparison. The studied components also fall into three areas of knowledge: psychology and education, sociology and culture, and ethics and religion. the number of components in the field of psychology and education is more than the other two. The research methodology of all studies was a content analysis method, and the sample of all of them was the child books, which was determined according to five criteria: year of publication and age group, author's name or particular book, type of story, specific subject, and selected books. Among them, the first criterion has been most widely used. Finally this study outlines the critical areas of research on children’s literature and identifies areas of further research.

Abstract
In today's competitive world where innovation is a condition for the survival of any organization, it is important to know the level of innovation capacity of the organization's resources, which is related to organizational policy, technology transfer, life and competition of the organization. The main purpose of this research is to design a model to determine and predict the level of innovation of organizational resources. After reviewing the available sources and interviewing experts, using confirmatory factor analysis, 12 main indicators in the form of 3 dimensions were determined as input to the fuzzy inference system. Among the new modeling methods, fuzzy systems have a special place in various sciences. Neuro-adaptive fuzzy inference system (ANFIS) is a good way to solve nonlinear problems. This method is a combination of fuzzy inference and artificial neural network that uses the ability of both to model. Using three types of model design methods in the fuzzy system and comparing the results, the best result for presentation was determined. To evaluate the performance of the model, the parameters of squared mean square error (RMSE), relative error percentage (ε), mean absolute error (MAE) and coefficient of determination (R2) were used, which were 0.047, 1.02%, 0.046 and 989 / Is achieved and indicates the accuracy and reliability of the model. This research is applied in terms of purpose and survey type according to the data collection method. The output of this study is ANFIS.

Abstract
Aims: Attention-deficit/hyperactivity disorder affects approximately 5.3% of children globally, causing significant functional challenges. This study examined the relationship between parental stress-coping strategies and the quality of life in children with this disorder.
Instrument & Methods: In this cross-sectional analysis, 220 children with attention-deficit/hyperactivity disorder (aged 8 to 12 years) and their parents were selected from medical centers affiliated with Babol University of Medical Sciences in 2023. Diagnoses were confirmed by a child and adolescent psychiatrist using DSM-5 criteria. Parents completed the Coping Inventory for Stressful Situations-Short Form, while the children's quality of life was assessed using the Pediatric QoL Inventory.
Findings: Children rated their quality of life and its specific aspects higher than their parents did. A significant difference was observed only in the emotional coping strategy within the emotional functioning domain, where children in the high-quality-of-life group reported better scores (p=0.017). Other dimensions and coping strategies did not show statistically significant differences (p>0.05). Furthermore, from the parents' perspective, no significant associations were found between stress-coping strategies and their children's quality of life across any dimension (p>0.05).
Conclusion: Parental coping strategies, particularly those involving emotional support, play a key role in shaping the emotional experiences of children with ADHD.

Abstract
Production of double-stepped metal sheet parts is considered as a complex and difficult task in industries. The crankcase is such a complex double-stepped part for the automobile industry, which its production with traditional methods is associated with many problems. In this paper, the formability of this stepped part has been studied experimentally and by simulation using hydrodynamic deep-drawing with radial pressure. It is shown that the crankcase can be formed successfully in one step by the hydroforming process. Moreover, the effect of fluid pressure on the thickness distribution and die filling and the effect of geometric parameters such as punch corner radius and the height of the steps on the thinning, and also optimal shape design of the original blank were investigated. The study showed that choosing the correct forming pressure can improve formability and increase the amount of die filling. It is also illustrated that by increasing the punch corner radius, the maximum thinning is reduced and the thickness distribution is improved and by increasing the height of the steps, thinning in the wall of the first step and the punch corner radius increase and by decreasing the height of the steps, thinning position will be shifted toward the second step. Also, by optimizing the original blank, it has been concluded that the optimization of the shape of original blank has a major impact on the material flow and will delay the sheet rupture.
