Preface

According to the long-term plan accepted by the Editorial Board, at the end of September 2012 we present to our readers the 32nd issue of the Polish Journal of Commodity Science. According to the ministry requirements we have established theme editors and the statistical editor for our journal. Continuing efforts to widen the group of our readers we present some papers in English version. As before, regardless the language of the original publication, each paper contains a wide summary in both Polish and English. The summaries of all the works published one can find on our webpage http://www.tpj.pr.radom.pl. Just before the summer holidays Polish commodity science suffered a serious loss. In the last days of May 2012 Marzena Ucherek, professor of UEK, elected deputy dean of the Faculty of Commodity Science (University of Economics in Kraków), passed away. The remembrance was prepared by prof. Małgorzata Lisińska-Kuśnierz. A series of 10 articles of the current is opened by Szymusiak's work. It is a review of the methodology of selected neuroimaging techniques. The author pays attention to the great practical importance of techniques involving the use of neuroimaging in marketing research and discusses the most important results described in the literature. In this work special attention was paid to neuromarketing, especially to those which empirically confirmed the impact of price and product quality on customer satisfaction. The paper provides an introduction to a series of problems in the field of neuromarketing presented in the recent book by Professor Szymusiak entitled "Neurobiological techniques used in business" recently published by the University of Economics in Poznań. In the consecutive work Wolniak deals with the issue of system approach to management. The author discussed the issue of self-assessment in quality management systems. The results obtained via a factor analysis of the self-assessment of pro-client orientation were presented. Application of factor analysis helped to reduce the number of self-assessment factors of quality management system to the three factors, such as identification and measuring of customer satisfaction, the resources necessary to meet the needs of the customer as well as the customer identification and communication needs within the organization. In the next paper Giemza wonders whether prestigious business awarded to the company for the quality of previous activities affect its level of functioning. This work concerns three organizations that won the Małopolska Quality Award. The author concludes that the impact of this award depends mainly on the profile of the company activity. There was no such effect for service companies, while the prize had an impact on the further development of the manufacturing companies. The issue of security in maritime transport sea is the subject of the article by Popek. So far, she used to put attention to the problem of liquefaction of bulk commodities, mainly sulphide ore concentrates, during transport by sea. This time the author discusses the issue of self-heating of raw materials in maritime transport. The evaluation of the ability of sulphide ore concentrates to self-heating and the physico-chemical characteristics of processes occurring in such charges was made. It was found that information on concentration of elemental sulfur contained in the concentrates of sulfide ores could be a good practical indicator describing susceptibility of the sulphide ore concentrates to self-heating. The ecological safety of textiles is the subject of the next article. Koszewska discusses the opportunities for development of biodegradable fiber materials on the Polish market. In her opinion, these materials constitute a practical response to the growing problem of environmental pollution by postconsumer waste textiles. The author believes that the introduction of environmentally-friendly, biodegradable polymers have a good chance for wide application in the Polish textile and clothing industry. In the consecutive paper Pawłowa analyzes the main systematic problems of clothing quality. Some aspects of the leather and textile production processes are discussed in the context of relationship: structure - the comfort of use. The author presents the determinants of the quality of clothing and footwear. The most important of them are: the quality of materials, innovative technological processes, design and solutions applied in development of new models of shoes and clothing. Cierpiszewski and Korzeniowski in their article assessed the individual packages for grain and milling products in retail. The authors investigated the extent to which they met their packaging functions. Protective, informative, practical, environmental and marketing functions were analyzed. It was found that packaging of grain and milling products well met the first four of these functions, while the ecological function received distinctly lower scores. The assessment of the freshness of the trade salmonids is presented in the paper by Zapletal et al. On the basis of the research carried out in Krakow retail outlets it was stated that the freshness of the fish offered for sale depended on the season - the worst was recorded during summer. It was also found that the most effective methods for the detection of bad meat were: organoleptic tests, assessment of the water filtrate extract from the meat and the indication of the total number of bacteria. Pietraszewska-Pająk focuses on changes in determinants of honey quality during storage. The author discusses the results of research on the effect of storage conditions on the color of heather and rape honey. It was found that heather honey is more susceptible to color changes than rape honey stored in the same conditions. The last article is devoted to quality of waste water generated in the food industry. Żmudzinski presented the results of research on the applicability of photocatalytic processes to improve water quality on the example of model sludge systems containing sucrose. The thirty second issue of our quarterly is closed by the column „TPJ announcements". It contains information on periodic international conference „Current Trends in Commodity Science" organized every two years by the Faculty of Commodity Science, Poznań University of Economics. This year's edition will take place in September, in Mikorzyn near Konin.

 I wish you a nice reading.
