Object and purpose of research. The object of study is small waterplane area twin hull (SWATH) ships whose main advantage is their excellent seaworthiness. The purpose of this work is to demonstrate the broad capabilities of such vessels. Materials and methods. The knowledge from foreign literature along with the author’s data are employed. Comparison methods focus on the main specific features of the technology for different fields of application. Main results. Brief review of the SWATH background is given highlighting the main trends of development. Common features and differences of each SWATH type is identified. The revealed merits and disadvantages, design details point to a broad range of possible applications. Conclusion. SWATH architecture may provide a considerable improvement in seaworthiness of small and medium displacement vessels. SWATH is an economically viable option for all types of marine vessels with a relatively large deck area, so-called capacity carriers, like passenger, research, ro-ro, naval ships, etc. For more efficient application it is recommended that alternative SWATH projects should be developed at an early design of vessels for the above missions.

Due to a common intellectual heritage, journalism and political science share a number of common features, for instance their object of study, sources, and methods. Consequently, the two professions can engage in a fruitful partnership and in fact often do benefit from one another both in terms of teaching and research. For instance political scientists often use journalistic articles as source of information on a given matter, and journalists often cite political scientists as sources for their articles. At the same time the two professions have their distinct identities that sometimes makes their relationship difficult. However, as in any well functioning partnership there must be differences and  individuality or it won’t work!

The article examines the socio-economic causes of the outcome of the Spanish Civil War (1936-1936), which, as opposed to the Russian Civil War, resulted in the victory of the “Whites”. Choice of Spain as the object of comparison with Russia is justified not only by similarity of civil wars occurred in the two countries in the XX century, but also by a large number of common features in their history. Based on statistical data on the changes in economic well-being of different strata of Spanish population during several decades before the civil war, the authors formulate the hypothesis according to which the increase of real incomes of Spaniards engaged in agriculture is “responsible” for their conservative political sympathies. As a result, contrary to the situation in Russia, where the peasantry did not support the Whites, in Spain the peasants’ position predetermined the outcome of the confrontation resulting in the victory of the Spanish analogue of the Whites. According to the authors, the possibility of stable increase of Spanish peasants’ incomes was caused by the nation’s non-involvement in World War I and also by more limited, compared to Russia and some other countries, spending on creation of heavy (primarily military-related) industry in Spain.

This research is motivated by the lack of interest of teachers in the use of props in the process of learning mathematics in elementary school. In accordance with the demands of the curriculum in 2013 and supported by the developed learning theory, learning mathematics is abstract object of study, students need an intermediary that props math-ematics, so that students can more easily understand the concepts that will be pre-sented, and in the end it can deliver students to solve mathematical problems, not only that proposed by the teacher but also the problems in life. The purpose of this study was to determine the interest of prospective elementary teachers on the use of props mathematics after getting lectures media and elementary mathematics learning model. By knowing the interest of prospective elementary teachers will be developed further realization of the state of the subject being studied. The method used is descriptive research, then the instruments used were questionnaires and interviews. The results of this study stated that the interest of prospective elementary teachers on the use of props after attending lectures media and elementary mathematics learning model is high over-all with a percentage of 76.70%.Keywords : Interest, Props Mathematics

Psychology and sociology share a common object of study, human behaviour, but from different perspectives. Sociologists have focused on macro variables, such as social structure, education, gender, age, race, etc., while psychology has focused on micro variables such as individual personality and behaviours, beliefs, empathy, listening, etc. Despite the importance of interpersonal relationship skills, they depend on the community or social context in which communication takes place, and by themselves may have little relevance in the consultation. The purely psychological analysis of the doctor-patient relationship often leads to an idyllic vision, with the patient-centred consultation as the greatest exponent, which rarely occurs in real life. The purely sociological or community / social analysis of the doctor-patient relationship leads to a negative view of the consultation, which is always shown as problematic. But, the psychological system in the doctor-patient relationship cannot be neglected, and its study is of importance, at least as an intermediate mechanism that is created through socio-community relations. Although the same social causes are behind the doctor-patient relationship, when acting on psychological factors in the consultation, they act as an optical prism scattering socio-community relations that affect the doctor and the patient, giving rise to a beam of different colors of doctor-patient relationship. In doctor-patient relationship there is a modality of psychotherapy, where attitudes, thoughts and behaviour of the patient, can be change, as well as it can be extended on the way of understanding and therefore changing, his social context. Because of the distance between socio-community relations and the form of doctor-patient relations is growing in complex societies, under these conditions, the sociological factor gives the important place to the psychological factor. Given these difficulties of the doctor-patient relationship one may ask how general medical practice can persist with the usual model of doctor-patient relationship. Pain and the desire to relieve them are the basic reasons for the patient and the doctor, and they do not disappear due to the contradictions of the doctor-patient relationship. In this way, the confrontation between sociological and psychological vision is replaced by an alliance of both currents, and each of them takes on meaning only in the general vision.
