Teaching physics, as any other natural science, is directed to laying the foundations of the science first, followed by further building up of specific knowledge, irrespective of the level at which the subject is taught. The process invariably involves overlapping of previous and new knowledge, on one hand, and knowledge overlap from subjects marginal to physics (mathematics, chemistry, biology), on the other.
It is known from physics that interference may occur under certain conditions, when two mechanical oscillations overlap, i.e. a picture in which sites with interference minima and maxima can be observed. The condition required is that the sources must be coherent, i.e. must have identical frequency.
The theory of this purely physical process can be successfully applied in physical text analysis, with the purpose of following the interference within the subject itself, as well as among subjects marginal to physics.
Keywords: interference, physics, text.

The assessment of the engineering education with the help of an ergonomic approach is one possible and necessary method for feedback in the Assesment and Maintanance of the Quality of Education System. (AMQES).
From the research with an ergonomic control card of the basic factors of the engineering training can be concluded:
- there exists motivation and satisfaction from the choice of the engineering profession among the students;
- the training of the UCTM students in terms of theory is “very good” for 45 % of the interviewed students, and for their specialised training a “very good” assesment give 20%. The practical training is a weak part in the training – 52 % assess it as “unsatisfactory”.
The students make relatively great but bearable efforts for their training. The students’ health is a factor that has to be taken in mind together with the success in the education.
Keywords: quality of education, Assesment and Maintanance of the Quality of Education System. (AMQES), ergonomic approach, ergonomic control card.

The change of market conditions brought to the changing of accents in marketing. There is a necessity of proceeding from the marketing with orientation “inside- out” to marketing with orientation “outside- in” that submits an accent not only on the product, but on the individual relations with the customers, too. In the article, the external and internal factors are under consideration, that have influence on the business success. Beside the customer satisfaction, we discuss other strategy approaches such as economical, technological, contractual binding and binding of customers with a trust and a commitment. We present in the article, by way of example activities of different instrumental fields, measures which can be used within the framework of instrumental implementation of customer binding strategy.
Keywords: customer satisfaction, economical, technological, contractual binding and binding of customers with a trust and a commitment.

Firm culture finds its application in the management of people in the production process and engineers need an appropriate training. In this connection the future engineer-technologists for the chemical and metallurgical production of the University of Chemical Technology and Metallurgy master the theoretical background and practical skills of firm culture. A level of their preparation, both theoretical and practical, is evaluated by setting on everybody a specific observation in real surroundings. This task consisted of two stages. The first practical task required eight factors for increasing of labour productivity to be arranged according to their significance. The objective the second practical task was to concede a possibility to the students to investigate and to analyse the firm culture of their own university.

The article presents the advantages of a collateral evaluation through a combination of an examination and a didactic test.
Analyzed are the types of control and the essential qualities of the examination, the didactic test and the combination of these methods, including via internet. The examination and the didactic test are explored separately, determining their benefits and shortcomings.
A well motivated conclusion is drawn to the fact that the combination of an examination and a test considerably reduces the disadvantages of each method of evaluation. The presence of a "person" behind the test ultimately raises the interest of those being assessed while the results of the test maintain the perception of security during an examination. The formation of a combined assessment eliminates or reduces the disadvantages of the evaluation process conducted solely by means of an examination or a test. The article concludes that the disadvantages of each method of evaluation - either test or examination - may be significantly diminished when they are used to form a collateral assessment while their advantages are well maintained.
The authors devise an exemplary methodology for executing control over the learning process using these two methods in a combination.
Keywords: didactic test, examination, collateral assessment.

The proposed system for check-up and control of Bulgarian language knowledge is a complex of tests and written examinations, based on the school material studied throughout the preparatory course in Bulgarian language for foreign language students. The system is coordinated with the changed nationality of the students at the Medical University of Plovdiv during the last years /mostly from Turkey/, which requires new methodical priorities.
The different level and time of mastering the language make necessary the complex use of tests and written examinations more frequently.
The system includes four tests and four written examinations for the First Semester and two tests and two written examinations for the Second Semester. The test – written examination ratio is made on the “levels’ gradation” principle. The tasks are divided into groups depending on the studied grammatical categories. The greater control frequency gives the opportunity for a more effective check-up of the acquired skills on a phonetic, lexical, morphological and syntactic level, as well as the command of the literary language norm. The attained results allow a well-timed interference of the teacher in cases of insufficient acquirement of the amount of knowledge, as well as overcoming some frequently noticed mistakes.
The principle of structuring the tests and the written examinations is different – at the tests a higher level of orientation is activated and at the written examinations a check-up of systematics and consistency is required.
The proposed system for check-up and control of Bulgarian language knowledge at the preparatory course of foreign language teaching is open to continuous enrichments and renovations.
Keywords: test, written examination, control, check-up, grammatical categories.

Everyone must possess physical and psychological endurance to perform certain activities in the tense atmosphere of everyday life. The situation of the students is the same – many of them not only study but they also work to make their living. Their health and workability is important condition for success and realization in the future profession. That is why the teaching staff of the Department of Physical Education and Sports at the UCTM have pointed their efforts in that direction – they try to improve the general physical condition and to have positive influence on their phyche. Regular participation in sports classes helps decreasing mental stress and develops striving to improve the personal qualities. The students acquire the mentioned components of sports training as well as basic theoretical knowledge and technical and tactical skills of practiced sports discipline.
There has been established a purpose to search students ideas for improving the teaching process of physical education with using an inquiry and to perform comparative analysis with the results of former years.
We can say that the time for increasing the number of sports classes at University and particularly at the UCTM has come. That is because students need more movement and ways to keep their health. The established approach will have social part – attracting more young people to sports and not to negative habits – smoking, drinking alcohol and taking drugs. The sports facilities of the University should also be improved with some up–to–date constructions for preventing injuries, increasing the satisfactory effect of sports classes and establishing hygiene habits of students.

The research paper examines the opportunities to have foreign students studying Bulgarian get acquainted with narrative literature. Interpretation of the text is based on an attempt to identify the explicit meanings of the three communication planes (according to the classification of O.-Slavinska - Saparev), as well as to establish the hierarchy of their levels.
This method allows the students to broaden their perceptions of the symbolic nature of the text, as well as to master and develop decoding techniques. Furthermore, in the process of their own individual interpretation students can get involved into the other proofs of the de-multiplicative nature of fictional discourse.
The research is based on authors and literary pieces with considerable differences in their intentions according to the principle "differentiation between character-donator - narrator - implicit author".
Keywords: interpretation, de-multiplication, narrator, implicit author, intention.

Thermodynamics is an abstract field of theoretical physics and naturally foreign students have difficulties in learning it.
Bioenergetics, which deals with the energy exchange between organisms and the environment, requires gradual progression into the theory of thermodynamics.
The aim of the is to offer a methodological elaboration on the topic. By combining the knowledge in physics, chemistry and biology already accumulated, and the intuitive notions of temperature, heat, work and energy, the students from the preparatory course get acquainted with the basic concepts, principles and regularities of thermodynamics, without going further into their theoretical explanations and mathematical deductions. Thus the students can use the to understand and learn the physical, chemical, biophysical, biochemical and physiological processes studied in the preclinical departments of the Medical Universities in Bulgaria.

Thermoelectric phenomena find application in measuring temperature and in transforming heat into electricity. The absolute thermoelectric power of a metal can be obtained experimentally. Recently, a method proposed by Prof. Brodowsky permits its estimation from data of the electronic structure. In the present paper this method, together with quantum mechanical data for the electronic density of yttrium published by the group of Prof. Papakostantopoulos is used for the estimation of the temperature dependence of the thermopower of yttrium.. The calculated values are compared with the experimental data in the paper of Prof. Vedernikov. It is shown that in a definite temperature range a good coincidence is observed, which can be treated as a proof for the application of the method used.
Keywords: thermoelectric power, yttrium

The synonymy and repetition have their own place in all styles. To a great extent their using frequency depends on the particularities of the style. Their participation in written literature is less dependant on the topic of discussion.
The research is actually a comparison between the use of synonymy repetition as lexical forms in different texts associated with medicine. We come from the idea that the synonyms are a device for diversifying and/or enriching the expressing form, for achieving great expression. The repetition usually minimizes the quibble and reduces the possibility for various interpretations of the written text. In this direction certain reciprocity, character is defined predominantly from the written style, is presumed in the use of both forms in the framework of a text.
Five products with similar volume of the following styles are examined: artistic, publicistic, scientific, informative, scientific-study. Quantatively a certain extent of use of synonymy and repetition is determined. The received data are statistically processed using the methods of variation analysis and the results are carefully studied. Certain differences in the frequency of use of synonyms and repetition in a style as well as in various styles are determined. The synonymy is most widely spread in the scientific style, and repetition – in artistic one.
On the background of peculiarities, typical for medical topics an attempt for explaining the registered interstyle and differences is made.
Keywords: synonymy, repetition, style, medical topics.
