Looking at the history of humanity, it can be observed that change can manifest itself in several different forms. The first of these is the change that took place due to the basic necessities of humanity such as food and shelter in the early ages, and then, as a result of meeting these basic needs, change can be found in the pages of history due to the need for enrichment. When viewed in the context of needs, it can be seen that the human being, whose basic necessities are met, now feels endless needs together with relatively wealth, and changes have taken place in order to provide quality life and comfort accordingly. These and similar examples can be increased, many forms of change can be mentioned, and the common point of all these is that every change brings with it absolute harmony. It is necessary to specify the adaptation of human to nature at the beginning, the harmony of the communities with each other in the social and economic context in the later change processes, and finally, the adaptation to the lifestyle in a way that will transform nature in order to provide comfort. Therefore, every change creates systemic changes in social, economic, political and ultimately health areas. In recent history, it can be said that scientific knowledge has also led the change, so that the change and subsequent adaptation took place in a shorter time compared to its previous forms. In today’s world, where borders are removed and the mobility of goods and services increases as well as the interaction of different social forms with each other through industrial and technological changes, which can be characterized as the outputs of accelerated change and adaptation processes, every system is almost globalized and in harmony with each other. Due to this globalization, in addition to the ordinary natural forms of change, obligatory and negative forms such as pandemic epidemics can also be encountered, and such an experience can cause a change by deeply shaking all macro-scale social, political and economic systems, from the comfortable life of the individual. Despite all these negativities experienced at this point, developments in the fields of technology and industrialization, which are the outputs of previous changes, can come into play in the form of natural selection and a new adaptation process between man and nature can begin. As can be seen, change manifests itself in different forms throughout history and an inevitable adaptation process can be mentioned depending on these changes. The most natural way for people to follow all these positive-negative change processes is to reach the academic studies made by valuable scientists. The most natural way for people to follow all these positive-negative change processes is to reach the academic studies made by valuable scientists. For this reason, this book with the theme of “Change & Adaptation” and similar academic studies; It is thought that it is very important for the readers to define and evaluate the processes of change experienced scientifically correctly. Because, within the scope of this international study, besides including the works of valuable scientists from different parts of the world, the themes of change and harmony; from consumer trends to health system, from art to cybersecurity, from education to marketing, from family businesses to accounting auditing. We would like to thank all the authors who contributed with their academic studies by writing chapters to this international study, with the belief that the valuable information of the authors will be beneficial to the readers
