Purpose: One of the main organizational planning is human resource planning. The purpose of this study was to design a model for the implementation of human resource strategies in the field of health. Methodology: The combined research method and research design were also of the type of mixed exploratory research design. In the qualitative section, using the method of "samples contain rich information" with 20 heads of medical universities and senior managers of the Ministry of Health and Medical Education, using the Delphi method and using semi-structured questionnaires; Was interviewed. In the quantitative part of the research, a researcher-made questionnaire with multi-stage relative stratified sampling method was distributed among 334 senior and middle managers of the country's medical universities and the data were used by exploratory and confirmatory factor analysis. Analyzed with SPSS and AMOS software. Findings: The results indicate that "human resource strategies" have six dimensions: 1. Human resource provision, 2. Training, 3. Performance evaluation, 4. Development and improvement, 5. Service reward and 6. Participation And "strategy implementation" has three dimensions and nine components as described: a- Structural dimension (1. structure of the implementing organization, 2. Capacities, 3. Resources), b- Environmental dimension (4. Macro environment, 5. Intermediate environment 6. Execution environment) and c- Behavioral dimension (7. Performers 'behavior, 8. Target community behavior and 9. Developers' behavior). The results of the quantitative section showed that the impact of all dimensions of human resource strategies on the structural, environmental and behavioral dimensions of strategy implementation was confirmed. Conclusion: Special attention to human resources, especially in organizations providing health services and health in the community as the most vital element of organizational success and creating a sustainable competitive advantage is always important in management.

Purpose: Epistemology as one of the philosophical foundations in the field of education can play an important role in blended learning, ie using more than one method, strategy and technique for learning. Therefore, the present study was conducted with the aim of designing and validation the epistemological model in blended learning Methodology: The present study was applied from type of qualitative-quantitative. The population of the qualitative section was the documents related to epistemology and blended learning in the years 1990 to 2020 which 80 books, 60 dissertations and 60 articles were selected by purposive sampling method and in addition, included experts in the field of philosophy of education and distance learning which based on the principle of theoretical saturation number of 10 people of them were selected by purposive sampling method. The population of the quantitative section were faculty members and doctoral students of the department of philosophy of education and distance learning of Payame Noor University in 2020-2021 years which based on Krejcie and Morgan's table number of 200 people of them were selected by stratified random sampling method with using the teacher and student ratio. The tool of the qualitative section was the recording of books, dissertations and articles and interviews with experts, and the tool of the quantitative section was a researcher-made questionnaire whose psychometric indicators were confirmed. Data were analyzed by coding method in MAXQDA software and exploratory factor analysis and one-sample t-test in SPSS software. Findings: Findings showed that the epistemological model in blended learning had 60 subcategories in 9 categories including purpose, evaluation, educational correction, content, teaching method, teacher, learner, media and cognitive presence that its model was drawn. Also, validation of model indicated that the factor load of all 6 questions related to validation of model was higher than 0.30, their validity was higher than 0.50 and their reliability was higher than 0.70. In addition, the mean of all 6 questions was higher than the hypothetical mean of the population (P<0.001). Conclusion: The findings showed that the designed model for epistemology in blended learning had good validity. Therefore, curriculum specialists and planners can use this model along with other models to improve blended learning
