In knowledge-based enterprises, the main capital is knowledge, and it is necessary to benefit from this capital by having knowledgeable employees who are lifelong learners. However, traditional learning approaches do not meet the needs of these enterprises. Based on this, the aim of the present study was to provide a suitable learning framework for knowledge-based enterprises. In order to achieve this goal, the meta-synthesis qualitative method of selection and in-depth analysis of the subject literature were employed based on the seven steps of Sandolowski and Barso. By reviewing the literature, 250 identified sources were analyzed using meta-synthesis method. The results indicated that the components of extra-organizational environment, organizational environment, the essence of knowledge-based enterprises and learning approaches are important aspects of the learning framework of knowledge-based enterprises. Each of these components included sub-components that affect learning in knowledge-based enterprises; therefore, considering the sub-components in the turbulent extra-organizational environment, the organizational environment is affected by the emphasis on agile structure, open culture, collaborative culture, organic job design and independent work space. The essence of knowledge-based enterprises was formed around the orientations including expertise, innovation, team, learning, communication and knowledge. Finally, the three learning approaches of interest in knowledge-based enterprises included experiential learning, self-directed learning, and collaborative learning, which in the literature were the most suitable for this kind of enterprises. Therefore, it can be concluded that paying attention to the identified components along with its sub-components could play an important role in formulating a suitable learning framework for knowledge-based enterprises.

Investigation on snake robots for pipe inspection purposes has been the subject of various papers. In this paper, we explore a unique type of snake robot that utilizes spherical modules. Ensuring proper contact between the robot and the pipe walls is crucial for successful climbing. If the normal force is too low, the friction force will not be enough for the robot to ascend, while excessive normal force can increase energy consumption. Therefore, it's necessary to investigate the robot's ability to move on sloped surfaces to ensure its practicality. In this paper, we present a new method for adjusting the robot's behavior on different surface slopes, which has been instrumental in optimizing its locomotion on sloped surfaces. Additionally, we have tested a novel torque control method to avoid boundary condition violations with promising results. The results of simulations conducted in MATLAB and Simulink have been validated by comparing them to existing experimental data. The simulations indicate that an excessive value of parameters in the proposed method can increase the generated torque by up to 295%.

The purpose of this study is to investigate the pathology of the internships of teachers accepted through the employment test. The present study was conducted as a qualitative method. The statistical population of the study consisted of teachers who were admitted to the recruitment test in 1397. In this regard, 12 interns were interviewed, and the results of the interviews were analyzed through content analysis method. Adoption of school interns, lack of qualified and capable guidance teachers, limited apprenticeships in urban and mono-elementary schools, lack of proper planning and poor supervision by tutors and teachers, lack of executive facilities and no paid work as weaknesses and increase self-esteem and stress reduction in class management and familiarity with Describe the power of school and class as the strengths of the courses. Overall, the findings of the study emphasized the weaknesses in the implementation of internships and on the other hand, the familiarity with the teaching profession.

The present study compared management styles in types of boy regular, public sample, non-profit and gifted high schools based on view of teachers in Tehran.This research is functional in terms of goal and descriptive – survey in terms of data collection method. . The statistical population included all secondary school teachers (regular, non-profit, gifted and sample public) in Tehran boys in the 2012-2013 school years. According to the Morgan Table, 165 public high school teachers, 201 non-profit high school teachers, 28 gifted high school teachers and 73 public sample were selected as a sample. The Clustered and Classified sampling methods were used in this study and the research instrument was questionnaire that its validity and reliability were acceptable. For data analysis, descriptive statistics (such as diagrams, frequency, percentage, mean) and inferential statistics(one-way analysis of variance test, LSD post hoc test, one sample T test and chi-square test were used. in general, the following results were obtained: 1-There are Significant difference in the usage of relationship-oriented and task-oriented management styles in the public, non-profit, public sample and gifted high schools. 2-There is no significant relationship between management styles and the type of schools. 3-there are no significant differences between dominant styles of management in the public, public sample , gifted Schools but there are significant differences in the non-profit schools so that the average relationship-oriented style is more than task-oriented style.

The purpose of this study is to identify the impact of staff training on empowerment of human resources. The study is applicable in terms of goal and descriptive-survey in terms of data gathering. The population are included all employees who have a high school degree and Considered to have participated in the training period, which are based on data obtained from 200 according to Morgan table, 76 people studied for sampling. Then the questionnaires were randomly distributed among the selected samples. The data-gathering tool is validated questionnaire, which has acceptable validity and reliability. For data analysis, descriptive and inferential statistical methods were used. The data were analyzed through independent T test, one sample Ttest, ANOVA, and Fridman test. Findings showed that employee training has a positive and significant impact on empowerment of human resources and stafftraining on empowerment dimensions (clear objectives ,ethical behavior, enhancing mood ,promoting team work and creating a healthy work environment) has asignificant effect. However, it is unaffected on constructive communication and the spirit of participation. In addition, some factors such as age, education, work experience and organizational capacity will affect the attitude of workers but type of educational course has no effect on employee's attitude towards education effect on empowerment of human resources. Finally, prioritizing the impact of staff training on empowerment show that promoting the moral has the highest degree, and the lowest one is dedicated to communication.

One of the most important and underlying marital problems in couples is marital disillusionment. The purpose of this study was to evaluate the validity and factor structure of the scale of the Marital Disillusionment Scale.
A sample of 188 teachers was selected with convenience sampling of students of Karaj. To calculate the convergent and divergent validity, attitudes toward infidelity scale, Kensas marital satisfaction scale, attachment styles & marital forgiveness were used. In order to assess the first order confirmatory factor of the marital disillusionment scale, the weighted lowest squares (WLS) and to assess the adequacy of the model to the data, the parameters of RMR, RMSEA, CFI, AGFI, GFI, c2, c2/df, and Dc2 were used.
Factor structure of the marital disillusionment scale was confirmed with using confirmatory factor analysis. Cronbach’s alpha and retest coefficients were 92.0 and 85.0 respectively. Correlation analysis showed that the marital disillusionment scale has a significant positive correlation with attitudes toward infidelity (p‍ First-order factor structure of "marital disillusionment scale" showed better fitness with the observed data. Confirmatory factor structure, reliability and validity of the marital disillusionment scale for research applications and clinical diagnoses were acceptable.
