Food allergies in rural areas

Introduction A food allergy is a group of symptoms occurring in the organism and resulting from consuming some food, where the problems are conditioned by immunological mechanisms. The symptoms may become apparent first in adulthood and they may be an initial manifestation of a latent allergy. Typical symptoms of a food allergy occur in different organs, thus not only in the digestive system, but also in the skin, respiratory system and circulatory system. Aim To assess the frequency of food allergy onset in rural areas of the Lublin region as well as to determine which factors induce such allergies. Material and methods A survey was conducted, involving the participation of 340 inhabitants of rural areas. The study monitored the knowledge and situation of the disease, concerning allergens, allergy symptoms, methods of treatment and opinions regarding such treatment. Results The analysis focused on 124 people with diagnosed allergies. Conclusions Introducing a diet did not result in a statistically significant difference regarding elimination of the symptoms, as compared to the patients who did not follow any diet. On the other hand, pharmacological treatment causes statistically worse results than using other methods or not being treated at all. The patients in whom allergy symptoms disappeared were more convinced about the positive character of their diet than those in whom the symptoms were not eliminated. The age when the allergy becomes evident does not affect its duration, yet it matters as to the time of its later elimination. The more symptoms were experienced by a patient, the longer the duration of the allergy was.

Multivariate analysis of textural properties of butternut squash during thermal treatment

In this paper, changes in the textural properties of butternut squash caused by thermal treatment in a convection steam oven with different levels of temperature, steam, and different process durations were considered. Textural properties of pumpkin pulp were measured in terms of five features (characteristics): hardness, chewiness, gumminess, springiness, and cohesiveness. Pearson’s correlation coefficients for measurements of the characteristics indicated significant linear relationships at a significance level of 0.05. This fact justified the use of multivariate statistical methods to explore the simultaneous impact of temperature, steam, and time on textural attributes of butternut squash. Shapiro–Wilk tests did not disprove the normality of four textural characteristics; namely, hardness, springiness, gumminess and chewiness. Based on the measurements of the four above normally distributed features, three-way multivariate analysis of variance with all double interactions between the factors proved their significant impact on textural properties of butternut squash pulp at a significance level of 0.05. Additionally, applied multivariate techniques such as canonical correlation analysis, principal component analysis, factor analysis, clustering analysis, and discriminant analysis explained relationships between the factors and characteristics under consideration.

ERP class tools in the strategy of production system management

Todays companies increasingly use a variety of systems and information technologies to make a better use of the firm capabilities and to optimize the business. The paper pays a special attention to the use of ERP tools as an effective support to the management of the production system. ERP is a tool that integrates all the processes in the organization by creating one general database. Basing on the database the efficient planning of the entire management of the company takes place. There are several firm resources which are being considered such as storage, inventory management, deliveries tracking, production planning, provision, sales, finance and accounting, customer 54 A. Dudziak, M. Stoma, L. Rydzak relationship and human resources management. The article also presents various strategies for ERP implementation.

Strategic importance of capital theory in the control of the production system

Paper presented the most important information about the various trends in capital theory and their critical analysis made from the perspective of the Polish School of Cybernetics achievements. The analyzes were carried out on examples of an isolated and real production systems. The functions of the subsystems of the production system and the possibilities of controlling its were described. There were two and only two ways to control the production system, and it was argued that the only controllable production factor in an isolated system was human labor.

Applying of CAAT’stechniques for making decisions in the certification process of QMS according to ISO9001: 2015

Due to the universal using of information technology in contemporary enterprises for data collection and processing, the paper focuses on presenting the areas and benefits of the one of the analytical tools supporting audit techniques -CAAT (Computer Assisted Audit Techniques). Particular attention has been pointed out to the use of CAAT techniques during carrying out audits in the certification process and, consequently, during making the decisions of the compliance, of the Quality Management System (QMS) with the requirements of ISO 9001:2015.
