<abstract><title style='display:none'>Abstract</title>Billions of people in the world are at risk of getting unsafe food. There is an urgent need to improve efficiency and effectiveness of food supply chains. The global population is expected to reach at least 9 billion by the year 2050, requiring up to 70% more food than nowadays and demanding food production and distribution to become much more sustainable. Today, food safety is a worldwide concern due to a number of food safety scandals. As supply chains become more globalized and complex, the ability to track and trace products from fork to farm becomes more difficult but remains equally important. Good traceability may minimize the production and distribution of unsafe or poor quality products. It allows targeting the product affected by a food safety problem, minimizing disruption to trade and any potential public health risks. The objective of this paper is therefore to conduct a comprehensive analysis of traceability methods and technologies in food supply chains.</abstract>

The competitive and turbulent environment generates the need to use various techniques to determine the level of product quality. In this aim, it is necessary to determine the direction of improvement attributes and function of the product based on customer requirements, which are usually uncertain. Therefore, the aim of the article is to propose the technique to improve the product quality by precisely determine the customers’ requirements and the importance of the quality parameters for the current attributes of the product. This technique is a combination of methods i.e.: the QFD method (Quality Function Deployment) with the GRA method (Grey Relational Analysis). Using the QFD method, customer requirements were translated into technical features of the product. In turn, using the GRA method the imprecise customers’ requirements were reduced and the importance of quality parameters was determined in a more accurate way. A test of a combination of the QFD and GRA methods for the household vacuum cleaner was made. The originality of the article is ensuring a precise study of the current attributes of the product from the point of customer satisfaction.

Intermodal transport has been one of the most supported forms of transport in the programs of EU transport policy and national conceptions of the policy. The effects of this support is still limited. By 2030 it is expected to improve the competitive position of intermodal transport in mature markets with innovation and technological progress and organizational. Intermodal transport market in Poland is a young market, which is characterized by a small, but steady growth. An increase in this type of transport in the overall transport of goods, but the share of intermodal transport performance in freight transport performance in Poland amounts to less than 5 % (the highest percentage of intermodal freight services characterized by foreign shipowners FTP sea - about 14 %). In this article, the author analyzes the current conditions shaping the intermodal transport market, and defines the areas in which it is necessary to implement changes and innovations that enable the sustainable development of the intermodal market in Poland. The strategic objective of the development of intermodal transport in Poland is to create favorable conditions for the technical, legal, organizational, economic and financial implications for the dynamic development of the intermodal transport system, so that their share of rail transport in 2020 reached the average level of the European Union in 2000, such as 10-15 % in terms of tonnage. (Tomasz Szmid 2012) The condition of the available infrastructure and various instruments, including financial ones, ensuring increased availability of intermodal services are also of decisive importance.

Since 1997, when the Kyoto Protocol was signed, the era of renewable energy has begun. Due to the growth of its share in the total energy production and consumption, the world community is making efforts towards the transition to sustainable development. Developed and developing countries have significantly increased production and consumption of renewable energy in absolute terms trying to join this initiative. The purpose of this work is to study the impact of changes in the share of total production and consumption of renewable energy on the economic growth and CO2 emissions. Secondary data of the World Bank, the countries that invest the most in renewable energy (the USA, China, the European Union) is used and a comparison with Ukraine, Russian Federation and general global indicators covering the period 1990-2015 is made. Modeling of the influence of the share of production and consumption of renewable energy sources in the total volume in the studied countries on the level of economic growth and CO2 emissions using economic and mathematical modeling is carried out. Linear regression models of the studied countries and the world are estimated. The hypothesis on a link between economic growth and development of renewable energy has been confirmed. The results reveal that depending on the country under the research the level and nature of the impact of increasing the share of production and consumption of renewable energy on economic growth differs significantly and depends on a number of political and economic factors.

Analysis of the Problem of Staff Allocation to Work Stations

<abstract><title style='display:none'>Abstract</title>The organization of space and working conditions is very important in terms of its effectiveness. Each professional work determines activities that support occupational safety and health at the workplace. Lack of proper working conditions but also the time of exposure to dangerous, burdensome or harmful factors has an impact on the effectiveness of the work performed. Lack of balance between work and leisure in turn results in a decrease in work efficiency. The scientific and didactic work of academic teachers is related to the occurrence of diversified occupational hazards with particular emphasis on those that are the cause of musculoskeletal disorders. In this elaboration, the research, analysis and evaluation of the work effectiveness of academic teachers have been carried out. A questionnaire and a direct interview have been used as a research method. In addition, the pain intensity in individual parts of the body has been assessed in the last 12 months depending on the age of research and teaching staff using the NMQ questionnaire (Nordic Musculoskeletal Questionnaire).
