   Nanotechnology involved tinkering to make important materials at atomic levels, manipulating and modifying substances 1, 00, 000 times smaller than a strand of human hair. It is expected that nanotechnology will revolutionize society as well as science. It involves one billionth of a meter of technology. The term (NANO) has been derived from the Greek word (Dwarf)[1].Nanotechnology is foreseen to significant influence science, economy and everyday life in twenty one century and it may become one of the driving forces to the next industrial revolution. Nanoparticles of Silver have many useful applications included spectrally selective coating for solar energy absorption and intercalation material for electrical batteries, as optical receptors

A new approach to the problem of full automation of production is considered. It is shown that along with technical issues, one of the main places among the issues of full automation of production is occupied by social issues, since full automation radically changes the structure of labor resources. The novel division of labor in the process of life activity led to the formation of new organizational solutions that also affected the automation environment. This is primarily due to the fact that along with individuals inventing and implementing automatic devices, a certain number of workers, who were freed from routine work by automats and had to be organized in a new way in the work of the team, appeared. The subsequent era of the industrial revolution is associated not only with the development of new types of energy, but also with the formation of new organizational solutions in production. It is reasonable to imagine the development of fully automated production as a process of transition to a state in which individuals who consume products simultaneously change its structure. The driving forces behind the development of fully automated production are individuals who have been freed from routine work as a result of automation and have been given the opportunity to realize their creative abilities. Taking into account the effect of the «universal law of the elevation of needs», it is necessary to consider the appropriate and most effective form of the structure of fully automated production as a permanently changing matrix containing a changing set of individual customers and a changing set of automation tools. Familiarity with the new approach to the problem of full automation will help enterprise designers to better understand the composition of tasks for the reconstruction of production.

In the era of Industrial Revolution 4.0, many companies are using social medias as one of their promotional tools, especially Instagram. The aim of this research is to investigate the influence of Instagram advertising and consumer perception on purchase intention in local building material stores. As this research is using a quantitative approach, the data are collected using questionnaires. The population of this research is the customers who have done several purchases and have followed the stores’ Instagram accounts. Out of the whole population, a number 100 respondents are selected through a purposive sampling technique. The collected data are processed using a SmartPLS program, with the results of no significant influence between Instagram advertising and purchase intention. However, the Instagram advertising has a significant influence on purchase intention through customer perception as the Instagram advertising has a significant influence on customer perception. Therefore, customer perception acts as the intervening variable in this research.
