The objective of this research was to study the degradation and biological characteristics of the three-dimensional porous composite scaffold made of poly(lactic-co-glycolic acid)/nanofluorhydroxyapatite microsphere using sintering method for potential bone tissue engineering. Our previous experimental results demonstrated that poly(lactic-co-glycolic acid)/nanofluorhydroxyapatite composite scaffold with a ratio of 4:1 sintered at 90ºC for 2 h has the greatest mechanical properties and a proper pore structure for bone repair applications. The weight loss percentage of both poly(lactic-co-glycolic acid)/nano-fluorhydroxyapatite and poly(lactic-co-glycolic

International Financial Reporting Standards (IFRS) are global, identical, high-quality and comprehensive standards for financial reporting that have been developed by the International Accounting Standards Board (IASB). The objective of the current study is to represent a model for the implementation of the International Financial Reporting Standards in Iran. This study is an applied research and can be considered a qualitative research. A survey is applied in this regard. The statistical population of the study consisted of members of the accounting faculty of universities, financial managers, and boards of directors of companies listed on the Tehran Stock Exchange and the Iran Fara Stock Exchange. In this study, the snowball sampling method was used. In this research, 15 experts were initially selected as the initial research sample, then 25 people were added to the initial research volume, and 40 people were selected as the final sample. Based on the results of the interpretive structural model, cultural factors are the prerequisites for all factors that affect the adoption and dissemination of International Financial Reporting Standards (IFRS), and the cost and benefits of applying IFRS have the same greater impact on the adoption and dissemination of these standards.
