In an immense market struggle, the only effective way to build a long-term competitive advantage is to provide a high level of quality. Offering quality to the market, the organization creates loyal consumers on the basis of which it achieves its profitability, growth and development. The research presented in this paper is aimed at determination of the impact of quality on improving business performance and customer satisfaction. Correlation analysis confirmed this influence on the basis of obtained statistically significant mutual relations between the analyzed variables. Quality was shown to have an impact on improving the business performance of the organization, primarily on profitability through the improvement of leadership and relationship management. The impact of quality on customer satisfaction was also confirmed, where the engagement of people and the management of mutual relations had the greatest impact on consumer confidence. The research confirmed that the training of employees in terms of quality had a statistically significant impact on improving customer satisfaction, if it is conducted in an efficient manner.

The development of science and technology introduces new approaches in plant breeding and various methods to increase plant productivity. One of the latest methods is the implementation of an environmentally friendly technique of using a pulsed low-frequency electromagnetic field (PEMP). The paper presents the results of the influence of the electromagnetic stimulation of soybean seeds on grain weight per plant, weight of 1,000 grains and grain yield in different agroecological conditions. In the three-year research, in the period from 2013 to 2015, the soybean variety Valjevka was used, grown with different amounts of fertilizers (control - without fertilization, 750 kg/ha and 1300 kg/ha). Before sowing, the seed was subjected to PEMP stimulation in variants: control - without stimulation and alternating magnetic field stimulation (PEMP) with induction of 30 mT and exposure time of 15 minutes. The average grain weight per plant during seed stimulation was 11.53% (12.09) higher than without PEMP (10.84). The weight of 1,000 grains with PEMP was 155.99 g, which was 2.06% higher than the weight of 1,000 grains of the variant without PEMP (152.83 g). The average soybean grain yield for all three years of research with seed stimulation was 4.85% higher (3,481.25 kg/ha) than without PEMP (3,320.14 kg/ha). Stimulation of seeds with PEMP has economic justification given the growth of soybean prices on the world stock market. The results show that the PEMP treatment of soybean seeds can significantly affect soybean grain yield and counteract side effects such as drought and lack of fertilizers.

Existing standards require welded joints with full penetration. It is considered that welded joints with complete penetration minimize the stress concentration in the root passage. However, there are numerous situations in the industry, in which the load-bearing capacity of the welded joint with partial penetration is satisfactory. If the tests of partially penetrated welds show satisfactory load capacity, the benefits compared to fully penetrated welds are reflected in lower costs, ie less time is required to prepare the joint, less additional material is needed, ie shorter time is required to make the welded joint. The paper presents the testing of butt welded joints of structural steel S355N, with partial penetration, achieved by the MAG welding in the overhead position (PD) in the protection of the gas mixture. The samples were welded with different welding parameters and with different joint preparation, and the tests were performed by non destructive methods (visual inspection, testing with penetrants and magnetic particles) and destructive methods - tension and bending tests, Vickers hardness testing.

Physical Culture, as a part of general culture, can be defined as a human activity, which, through its knowledge ABOUT and FOR physical exercise within its areas (physical education, sports and physical recreation), allows the transformation of personality from real to possible. Physical Education, as one of the areas of Physical Culture, is therefore a very important educational link. It is particularly important in anera characterized by fast technological advances and technicalism that is rapidly introducing people to virtual reality. Hence, we emphasize that Physical Education, with its knowledge ABOUT and FOR physical exercise, builds the basis for a healthy, active and long life in young people. This is possible due to the fact that Physical Education, based on the Theory of Theoanthropocentrism, sees physical exercise as a beneficial body activity necessary for man and stems from the relationship to a man as a person, not an individual. The increasingly present virtual reality is in complete harmony with the sedentary culture, increasingly dominant not only in Western civilization. This undoubtedly leads to "active" hypokinesia, the root of many disturbing changes and health problems. Anthropological research conducted in Serbia and AP Vojvodina have confirmed that the number of people who regularly engage in physical exercise is decreasing. That is why we point out the importance of Physical Education, which, with its knowledge of how and why to exercise, builds the awareness of the necessity for physical exercise, as well as of the possibility of seeing every physical activity as physical exercise.

Physical movement - an exercise, which springs from our being and returns to it as a gracious food, with its agon, that desire to compete with others but also with itself, helps a human being to become and remain a personality. This statement is confirmed by people who marked the 19th and 20th century. By their example and work, they not only testified the benefits of physical exercise, but also encouraged the formation of theoanthropocentrism, one of the theories of physical culture, at the end of the 20th century. Metropolitan Hadzi Sava Kosanovic, Bishop Rade, Bishop Nikolaj of Zica, Vasa Pelagic, Cedomir Milic, are just some of those who testified and encouraged others by their example not to forget about physical exercise and their body. Because in the union of body and soul sanctified by the Holy Spirit, that trinity survives only if all and each of them is taken care of, in specific. With examples of their attitude towards physical exercise and competition, which they only pointed out or others wrote about, we will lighten up a significant part of the history of physical culture.
