The economical situation at agricultural industry has been changed rapidly in Korea for the last 40 years. The population in farming area decreased sharply and the labor demand increased dramatically. The portion of the old and women has been increased. The farm size, and farm rural wage have been increased. Those were the driving forces of the mechanization in agricultural industry. The Agricu...

Debates over the effects of technological change on work continue to generate a wide and confusing array of findings. One reason for the lack of consensus is that empirical research based on large samples has yet to adequately address the core issue: the relationship, if any, between the level of mechanization and the characteristics of work. This relationship is explored using data from the 19...

This study aims to evaluate mechanization quality and quantity for improvement purposes. Northern Ahwaz including five districts with a total area of 286,800 hectares was selected for evaluation. The current potentials for scientific mechanization and suitable production methods in the study area were identified within the framework of a field study. In addition to a holistic study of the area ...

The mechanization of mathematics refers to the use of computers to find, or to help find, mathematical proofs. Turing showed that a complete reduction of mathematics to computation is not possible, but nevertheless the art and science of automated deduction has made progress. This paper describes some of the history and surveys the state of the art.

agricultural mechanization is a method for transiting from traditional agriculture towards industrial and sustainable one. due to the limitation of natural resources and increasing population we need to have economical production of agricultural crops. for reaching this destination; agricultural mechanization has a remarkable role. so it is necessary to have an extensive view for mechanization,...

Increasing the production rate and minimizing the related costs, while optimizing the safety measures, are nowadays’ most important tasks in the mining industry. To these ends, mechanization of mines could be applied, which can result in significant cost reductions and higher levels of profitability for underground mines. The potential of a coal mine mechanization depends on some important fact...
