Kefir is one of the oldest traditional fermented milk products, while it is very popular in Russia. Kefir contains mineral components, vitamins, essential amino acids, as well as several varieties of probiotic bacteria, which is so useful for health and important for nutrition. The purpose of the research was to evaluate the quality of kefir produced by the Center for the Protection of Rights (the village of Nizhnaya Sanarka, Troitsky district, Chelyabinsk region). Kefir 2.5 and 3.2 % fat content were used as an object of research. It was found that the samples of the drink under study were packed in clean, sealed bags of polymer film and in white bottles made of polyethylene terephthalate. The marking of the investigated kefir samples was incomplete (there was no sign «degree», the sign «To protect from sunlight», etc.) or incorrect (distorted terminology, numerical value of regulated quality indicators, etc.), and often - difficult to read, which violates the requirements of the state standard 51074-2003, the Technical Regulations of the Customs Union 022/2011 and 005/2011. In kefir 2.5 % fat, an excessively liquid consistency, an empty, unexpressed taste, a low acidity is detected, which indicates its immaturity and the inconsistency of quality with the current standards. The quality of kefir 3.2 % fat content complied with the requirements of the normative documents the state standard 31454-2012, the Technical Regulations of the Customs Union 033/2013. Such toxic elements as cadmium and lead in the samples of kefir were absent. According to Article 3 of the Federal Law No. 29 of 02.01.2000 «On the quality and safety of food products’ yogurt produced by the «Center for the Protection of Rights’ was recognized as improper implementation in retail trade.

Beef ageing is a technique used by meat technologists, retailers, and restaurateurs to intensify flavor and improve tenderness due to the natural enzymatic processes occurring in meat postmortem. There is a widespread consensus that meat should age to achieve desirable palatability and tenderness. However, taking into account obvious advantages and disadvantages it is questionable which technique of meat ageing is to be selected. The paper presents two techniques of beef ageing (dry and wet) and their effect on the final sensory quality of meat, weight losses, and microbiological status. On the one hand, dry ageing primarily augments the flavor of meat. On the other hand, wet ageing notably increases the meat tenderness. Unfortunately, dry ageing of unpacked beef (or beef cuts) is a process which requires specific temperatures, relative humidity, airflow, and high standards of hygienic conditions. In contrast, wet ageing of meat in a vacuum bag does not require such circumstances (with the exception of temperature). Moreover, wet ageing can further amplify the effect of dry ageing, thus creating an additional benefit. The main advantages of this combination are the constrained weight loss of beef and a substantial reduction in the risk of contamination. Although the dry beef ageing process is extremely time-consuming, requires particular attention and professional knowledge, it turns out that a narrow group of consumers is prepared to pay a premium for the properly manufactured final productthat stands out in terms of a unique taste profile. Furthermore, such a product is nutritious and completely safe from the health point of view (the lack of pathogenic microorganisms and mycotoxins as well as relatively low level of biogenic amines) when good hygienic and manufacturing practices (temperature, humidity, air-flow, careful treatment) are respected.

Online panels (OPs) are an important form of web-based data collection, as illustrated by their widespread use. In the classical sense, a panel is a longitudinal study in which the same information is collected from the same individuals at different points in time. In contrast to that, an OP has come to denote a pool of registered people who have agreed to occasionally take part in web-based studies. Thus with OPs, the traditional understanding of a panel as a longitudinal study is broadened because an OP can be employed as a sampling source for both longitudinal and cross-sectional studies. This article gives an overview of the current state of use of OPs. It discusses what OPs are, what type of OPs there are, how OPs work from a technological point of view, and what their advantages and disadvantages are. The article reviews the current body of methodological findings on doing research with OPs. Based on this evidence, recommendations are given as to how the quality of data that are collected in OPs can be augmented.

The article is focused on studies of domestic and foreign scientists concerning the aesthetic properties of landscapes. Different methodological approaches of analysis and description of the visual quality of landscapes are presented. The world experience in the application of methods to assess the landscape attractiveness of territories when arranging of recreational zones was studied. The analysis of different types of landscapes, their aesthetic advantages and disadvantages, as well as characteristics from the point of view of the arrangements of recreational areas was carried out. The relation between natural features of the area, its aesthetic parameters and the demand degree among vacationers was revealed. The features of the natural framework of the Belgorod region were determined; characteristic of regional landscape features, affecting the emotional perception of landscapes (chalk outcrops, wetlands of riverine lands, etc.) were identified. The assessment of the aesthetic attractiveness of landscapes is carried out using the territories of the Valuysky municipal district as an example. The localization of the areas with the greatest aesthetic attractiveness was determined and the promising territories for the development of recreational zones were identified. The compositional structure of the gully-like landscape was analyzed as one of the characteristic features for this region as a whole. Recommendations on the application of the assessment method for aesthetic of landscape attractiveness, taking into account regional characteristics the Belgorod region as an example were proposed.

The paper characterises a class of problems for packing boxes in the container. It presents the current state of knowledge in this area and distinguishes evolutionary algorithms, as the most promising in the search for quasi-optimal loading conditions. The method proposed in the paper focuses on certain criteria important from a practical point of view, which in a formalised manner have not been included so far in the solving-problems models. Apart from the traditional consideration of the problem of three-dimensional space loading maximisation, the proposed method considers the deviation of the loaded container weight centre from its symmetry planes and the availability of packages during unloading. New elements in the described method are: the applied criteria, penalty function, way of coding the container loading state in the evolutionary algorithm and fast crossover and mutations operators dedicated to the adopted coding. It was observed that the evolution in the developed algorithm occurs properly, that is seeking to minimise the criteria. The article also includes a calculation example showing the effect of the method with the discussion of the results indicating the advantages and disadvantages of the proposed solution. The performance of the algorithm has been considered in the context of time necessary to obtain the acceptable solution and quality of the obtained solution. It was found that the algorithm in its current form is a strong base for its further improvement.

The problems of higher university education are not only urgent but, it can be asserted, that due to many reasons they are getting sharper. The dynamism of labour market and always changing society require flexible, innovative and creative lifelong learning possibilities; higher education institutions do not limit themselves to primary preparation of specialists, the possibilities ought to be found for the development of specialists and professionals, for specialisation change, for the development of personal abilities and for expansion of high level professional competences. Continuing education at universities is becoming more and more urgent in the Strategic priorities of European education. It is necessary to seek for high scientific activity and high study level and for the results acknowledged on an international level. On the other hand, the competition among universities is evidently getting stronger both on national and international levels. Very often blind orientation only to a consumer (a student), only to service provision to him, make the quality of studies and at the same time the quality of acquirable education worse. The solution of any problem requires reliable and adequate information. The researches, regarding university students’ opinions on higher education problems do not lose their urgency. On the contrary, in this way rather objective primary information about processes taking place in this sector is obtained. The empiric research (N=544), carried out in January-February 2012, showed that student opinions on higher university education are controversial, in fact. Having carried out content analysis on the respondents’ expressed positions, considerable advantages and disadvantages of university studies were discerned. Education acquisition and good study quality are pointed out as the most important university education advantages. These positions have relatively the biggest weight among all categories defining the advantages. Self-realisation and career possibilities occupy the middle position in the advantage category scale. Their weight fluctuates in the interval of 10-20 percent. Communication possibilities and study management are not regarded as considerable advantages. It has been stated, that a considerable shortage of university education is study quality. One third of the respondents gave the biggest weight to that category. It can be asserted, that study quality and conditions for practical ability formation in the study process worry the respondents most. Evaluating study quality, the respondents most often express dissatisfaction with the overloading of the study content: a lot of insignificant subjects must be studied, too many unnecessary lectures, inexpedient lectures, poor lectures, worthless; a lot of unnecessary study programmes and so on. A part of respondents accentuate dissatisfaction with the teachers’ work: poor competence of some teachers, unfair student evaluation, the requirements raised are too high. It can be asserted, that university studies are more often understood as experience process, during which theoretical and practical knowledge are integrated and on this basis professional experience is acquired and professionalism is mastered. Key words: survey, empiric research, qualitative analysis, university education.

The article presents a model, which includes the list of consumer qualities for evaluation of technical level of washing machines using developed scoring system for each characteristics and parameters weight coefficients. The evaluation of washing machines according to developed model is performed and recommendations for improving of quality level of washing machines in technical field are given. Evaluation of safety, functionality and reliability of appliance is a base for quality evaluation of household appliances. This topic is actual because the normative documents regulate the requirements for the product, but there is no methods, needed for evaluation of product from technical point of view. Novelty of the topic is that developed methodic allow to evaluate technical level of appliance, to define advantages and disadvantages of produced products based on weighting factors of parameters, calculated according to consumer properties and technical characteristics. The authors of this article defined following tasks: to develop registers of consumer properties with detailed nomenclature of indicators for evaluation of technical level according to normative documentation, to calculate weighting factors of parameters for each level of consumer properties, to define measurement method of each parameter, to develop evaluation model for technical properties and scale for evaluation. The developed method was used in production of household appliances (washing machines). During evaluation process, a number of models were evaluated and the products with low technical level were identified. The developed method gives an opportunity for production firms to analyze quality of products from point of view of safety, functionality and reliability and to define parameters, which are needed to be improved.

Loss Of Autonomy

Background: The rapid increase in the number of older people with loss of autonomy and requiring human support, medical services, and adapted accommodation is a challenge in many countries. Beside institutions for older people, foster care families may offer an interesting innovative and affordable alternative that should to be evaluated. As the place of living has a major impact on the quality of life, our objective was to compare the perceptions and experience of older adults depending on the type of accommodation in which they live in.Methods: This study was based on a mixed method approach, with a quantitative assessment and a qualitative study with semi-structured interviews conducted with older people living in two different types of institutions: medico-social institution and foster care families. We explored the perceptions and the quality of life of the participants.Results: Institutionalization, chosen or not, can represent a trauma for older people as it disrupts their personal habits. Participants described medico-social institutions as an institutional framework supported by a strict professional team and rules, as impersonal structures (i.e., somewhat neutral), and as offering a very present, prepared, and respected reception protocol on the first day of arrival, which remained marked in memories. On the other hand, foster care families were considered as more spontaneous and family-oriented structures relying on internal and negotiable rules, offering personalized and close support in the face of loss of autonomy, but in which the reception protocol on the first day of arrival was almost absent.Conclusions: Foster care families and medico-social institutions presented different advantages and disadvantages from the point of view of the participants. This can help health policy makers to rethink the way seniors are housed by taking into consideration their perception and quality of life.
