Milan Kundera is one of the most influential writers in contemporary world literature. In his novels, there are many symbolic metaphors related to numbers, dreams, and animals. Combing through the plots of Kundera’s novels, we can discover that among all the numbers, seven and twenty are used most frequently. These two numbers have rich metaphorical meanings. Besides, there are many other digital metaphors in Kundera’s novels, including 6, 4, etc. Apart from number symbols, Kundera has also inserted various kinds of dream symbols in his artistic creation. For Kundera, dreams are not just an individual’s physical and psychological activities, but also a continuation and supplement of real life. It can be concluded that dream narration is a perfect medium for the author to express his philosophical ideology. In addition, dream symbols also serve as an important medium for Kundera to demonstrate narrative skills and present important themes. In Kundera’s novels, animal symbols are integrated with the plots, revealing the personal traits of the relevant characters, and mirroring their spiritual world at the same time. Besides, Kundera also expressed his ecological ethics through the narration of animals’ death. In conclusion, the metaphorical meanings of different symbols in Kundera’s novels play an active role in highlighting the themes, revealing the inner thoughts of the characters, showing the special features of the characters, and expressing the author’s philosophical thoughts. These symbols help Kundera to break the limitations of time and space, which has become an important part of his polyphonic art. What’s more, Kundera has also tried to expand the original metaphorical meanings of these symbols to create some new poetic meanings.

In the former 20 years, professional identity has arisen as a different study domain in the area of language instruction and education. Educators’ professional identity frames educators’ explanation of their functions, academic changes, and alterations in syllabi, class exercises, utilization of approaches and strategies, and their connection to other problems in the academic setting. Also, well-being is one of the elements in which its influence and connection with identity are noted in various studies. However, their roles in professional development have not been examined; hence, this review of literature aimed to investigate the role of these constructs in professional development which is regarded as a noteworthy aspect of teacher quality. In a nutshell, some implications are proposed for the scholastic stakeholders.

Objective Diabetes is a global public health concern. Management of diabetes depends on successful implementation of strategies to alleviate decline in executive functions (EFs), a characteristic of diabetes progression. In this review, we describe recent research on the relationship between diabetes and EF, summarize the existing evidence, and put forward future research directions and applications. Methods Herein, we provide an overview of recent studies, to elucidate the relationship between DM and EF. We identified new screening objectives, management tools, and intervention targets for diabetes management. We also discuss the implications for clinical practice. Results In both types 1 and 2 diabetes mellitus (DM), hyperglycemia substantially impairs EF in people of all age groups and ethnicities. Hypoglycemia can similarly impair EF. Interestingly, a decline in EF contributes to DM progression. Glucose dysregulation and EF decline exacerbate each other in a vicious cycle: poor blood glucose control, impaired EF, diabetes management task failure, then back to poor blood glucose control. Many pathophysiological indexes (e.g., obesity, metabolic index, inflammatory and immune factors), neuropsychological indexes (e.g., compliance, eating habits, physical exercise, sleep, and depression), and genetic factors are changed by this pathological interaction between DM and EF. These changes can provide insight into the pathophysiological mechanisms of diabetes-related EF decline. Conclusion Further studies, including large-scale prospective and randomized controlled trials, are needed to elucidate the mechanism of the interaction between diabetes and EF and to develop novel strategies for breaking this cycle.
