Technological advancements show themselves also in agricultural practices. As a natural result of this, modern agriculture's indispensable element tractor, has been effected positively from these advancements. As is known, tractors are indispensable power sources in agriculture. Efficiency of this power source is improved more with designs dependent on technological parameters. Certainly the ones that will improve humans' life quality among these designs are driver cabin designs. Driver cabin Systems were previously considered in terms of security, but now they are considered as environments of necessary comfort. These environments are thought in such a dimension that can contribute to tractor performance while providing the necessary ease of use to the driver in hard working conditions. In this paper, tractor design that maximizes the elements that one can expect from good life quality in scope of technological dimensions will be discussed with all aspects. Effective parameters in this design will be evaluated in quality-machine sense.

The concept of project management expresses an indispensable approach to imvestment projects. Time is often the most important factor in these projects. The artificial neural network is the paradigm of data processing, which is inspired by the one used by the biological brain, and it is used in numerous, different fields, among which is the project management. This research is oriented to application of artificial neural networks in managing time of investment project. The artificial neural networks are used to define the optimistic, the most probable and the pessimistic time in PERT method. The program package Matlab: Neural Network Toolbox is used in data simulation. The feed-forward backpropagation network is chosen.

This work presents the development and implementation methodology of technical support in IT1system operation. Methodology is developed and applied in realistic system (Information system of the Tax administration - DIS 2003), which is technically very complex and highly distributed. The results of IT system availability assessment and identification of the critical components are input parameters in the process of establishing of the technical support. The importance of technical support for achieving optimal IT system availability and IT service quality is assessed according to its operation during one year. The history of technical support system operation is a basis for further continuous improvement.

Presently, the most environmental pressure in Serbia comes from urban areas and associated industries,with collection, treatment and disposal all kinds of hazardous waste, non hazardous waste, and waste water being among the most challenging issues.There is an urgency to prevent further environmental degradation and to initiate new environmental and industrial management practices. Industrial systems reingeneering is one of possible solutions, from the authors stand point.

In order to motivate their group members to perform certain tasks, leaders use different leadership styles. These styles are based on leaders' backgrounds, knowledge, values, experiences, and expectations. The one-dimensional styles, used by many world leaders, are autocratic and democratic styles. These styles lie on the two opposite sides of the leadership spectrum. In order to precisely define the leadership styles on the spectrum between the autocratic leadership style and the democratic leadership style, leadership theory researchers use two dimensional matrices. The two-dimensional matrices define leadership styles on the basis of different parameters. By using these parameters, one can identify two-dimensional styles.

Every organization faces continuous quality improvement and needs to use an appropriate tools and techniques to achieve that. The basic requirements for success and solving the problems are use of quality tools which will guide you step by step to solve them. Contents of this paper try to use well known root cause identification tool with implementation at laboratory tensile test of reinforced steel, providing mechanical properties of metal specimen. Cause analysis tool are used when you want to discover the cause of a problem or situation or to gain desired results.
