This study was carried out in a car factory at workplaces in various states of activity. The measurements of substances enlisted as carcinogenic found at workplaces in some departments in 1995-1997 was carried out as well as the evaluation of microclimatic conditions and the evaluation of sick absenteism in the whole factory. Analysis of results revealed that microclimates in the rooms in the studied departments did not exceed permissible hygienic standards, except for some workplaces in the suspension springs department and the tool room. The analysis of exposure to particular/specific factors in 1995-1997 enlisted among carcinogenic substances did not reveal any toxicological health hazard. Sick absenteism in the whole factory and studied departments in the analyzed period varied. The prevailing group of diseases were diseases of the respiratory system. Morbidity from cancer was low.
The goal of solving relationships in the system „human – machine – environment“ is reaching the optimal functionality of the system at minimal costs so that well-being, health protection and safety of human at work may be maintained. In this article is introduced a simple model which can be utilised at optimisation of work position as well as workplace as a whole. The solution is proposed so that it may respect the basic ergonomic criteria.
The process of dismantling the design process is a complex set of overlapping activities which require knowledge and individual approach designer. article discusses trends in the design of the dismantling process, based on the knowledge base for designing of the assembly processes.
Agritourism is a chance in view of attractive for municipal population, healthy and relatively cheap rest. First of all it constitutes an additional earnings source for agricultural farms as well as development of infrastructure of country region. The development of agritourism is one of the ways to improve countryside areas. It helps local communities to get additional income. The most important aim is also to create new work places and diminish unemployment. It is also a chance for small farms to develop and keep production. The aim of this article is to evaluate the development of the agritourism and its influence on the transformation in agriculture and rural areas in the Bytów district.
The aim of the research was to estimate personnel knowledge of hygiene practices assurance in the catering industry. The research was conducted in a form of a questionnaire among 200 employees of hotel catering establishments. Over 20% of the respondents were uncertain as to the existence of the HACCP system at their workplace, which may mean that there are not enough HACCP system trainings and that the system does not function properly. The questions concerning the personnel hygiene were answered correctly by most respondents (about 90%). Different answers were given to the question about how often protective clothing should be changed (only 60% of correct answers). The staff’s knowledge about ensuring proper hand hygiene was sufficient. The respondents found the part about technological processing most difficult. Many of them were not familiar with correct rules of thawing food (11 persons claimed that thawing food in hot running water is the right method). They knew that thawed meat cannot be frozen for the second time, but 1 of them said it can be kept in cold storage for 5 days after thawing. They were not able to define the safe shelf life dishes. They knew the basic rules of GHP and had no difficulties with answering questions about hygiene assurance in a catering establishment. On the basis of the conducted research it can be stated that the know-how of the hotel catering staff is not fully satisfactory, especially their understanding of the correctness of food processing. The hygiene employee trainings should be introduced to explain the concepts, principles and idea of GHP, GMP and HACCP systems, and their implementation should be controlled afterwards. Only the personnel’s full understanding of hygiene principles guarantees the proper quality of the catering service.
Efficiency of L-carnitine endogenous biosynthesis in humans depends on the presence of cofactors of numerous enzymatic reactions. Among others, the role of cofactor is played by vitamin C and vitamin B6. The objective of our study was to evaluate the influence of vitamins C and B6 stores on plasma carnitine level in healthy humans. The examined group consisted of 52 healthy volunteers. Total (TC) and free (FC) carnitine, ascorbic acid (AA) in plasma and indices of vitamin B6 in plasma and in erythrocytes were determined. Mean TC was 52.2 ± 10.7 mmol/1 and FC 44.4 ± 9.5 mmol/1. Mean AA was 0.4 ± 0.3 mg/dl. In 40% of examined group AA levels were out of the reference range. B6 indices in plasma and erythrocytes were 1.21 ± 0.23 and 1.42 ± 0.33, respectively. Vitamin C and vitamin B6 did not influence carnitine plasma levels, that confirms the marginal role of endogenous biosynthesis in the carnitine balance in healthy subjects. Moreover, a significant distribution of vitamin C deficiency was found in the evaluated population.
