Opis:
The assessment of teachers’ exposure to noise in primary schools was carried out on the basis of: questionnaire studies (covering 187 teachers in 3 schools), noise measurements at the teachers’ workplaces, measurements of the school rooms acoustic properties (reverberation time and speech transmission index STI in 72 classrooms), analysis of statistical data regarding hazards and occupational diseases in the education sector. The studies have shown that noise is the main factor of annoyance in the school environment. Over 50% of questioned teachers consider noise as annoying and near 40% as very annoying or unbearable. A-weighted equivalent continuous sound pressure levels measured in classrooms, teacher rooms and common rooms are in the range of 58–80 dB and they exceed 55 dB (criteria of noise annoyance). The most frequently reported subjective feelings and complaints (over 90%) are: growth of psychical and emotional tension, irritation, difficulties in concentrating, hoarseness, cough. Noise in schools is also a harmful factor. High A-weighted equivalent continuous sound pressure levels ranging from 80 to 85 dB, measured in corridors during pauses and in sports halls, can cause the risk of hearing damage among PE teachers and persons oversensitive to noise. The latter concerns both teachers and pupils. High background noise levels (55–65 dB) force teachers to raise their voice. It can lead to the development of an occupational disease – chronic voice disorders due to excessive vocal effort lasting for at least 15 years. In the education sector 785 new cases of this disease were reported only in 2008. Poor acoustics in classrooms (reverberation time ranging from 0.8 to 1.7 s, STI < 0.6 in 50% of classrooms) have an adverse influence on speech reception and make the teaching and learning processes difficult.

Opis:
Since March 11, 2020, the global community has faced the challenges of the COVID-19 pandemic. In response, numerous countries, including the Republic of Lithuania, mandated the wearing of face masks to curb the virus’s spread. Yet, a section of the Lithuanian populace resisted this move, voicing concerns about the inconvenience of mask-wearing and potential privacy infringements. These concerns endured, even amidst debates on the masks’ effectiveness. This article explores how the Lithuanian public responded to mask-wearing protocols during the pandemic. Survey analysis highlighted a troubling trend: many individuals dispose of face masks with their regular trash, often without proper packaging. Most masks are sourced from pharmacies or are provided by employers and are typically thrown away after just one day of use. The data underscores a significant knowledge gap in correct mask disposal, as a significant portion ends up mingled with general household waste, without proper containment. Moreover, many people keep used masks in pockets or bags. Notably, during the pandemic, an estimated 2 mln adult Lithuanians may have generated roughly 15.24 Mg of hazardous plastic waste through mask disposal.

The objective of this article is to show that project management practices present key success factors for implemented a Quality Management System (QMS) in Moroccan companies. In general, the organizations seem to look at the implementation of a quality management system as a project and they employ standard project management tools, albeit to a different extent and in different ways. Following a qualitative study in Morocco, the companies, whatever their sector of activity and size, use different practices in the framework of the project QMS. Information was collected from practicing managers. The data analysis shows that project management practices present a great opportunity for the successful implementation of QMS within Moroccan companies.

Opis:
Annoyance due to wind turbine noise is usually assessed on the basis of surveys conducted among people living in the vicinity of turbines or in the laboratory conditions. Due to the fact that the latter are very different from natural conditions, we propose a solution to reduce this difference. Prior to the surveys, 50 participants were asked to familiarize themselves with 5 environmental signals. They were informed about the annoyance rating assigned to each signal (obtained earlier in laboratory conditions), expressed as a number between 0 (not annoying signal) and 10 (extremely annoying signal). Participants were then presented with new environmental sounds and asked to rate the annoyance caused by each sound, in accordance with the previously learned method. The analysis of our results shows that the variability of answers given by respondents at their homes is similar to those obtained earlier in laboratory conditions.

Polish Panel Survey (POLPAN)
Opis:
Sociological, qualitative, biographical research is distinguished by its interest in the case. At the same time, this research seeks—often through case studies—to understand or explain supraindividual, repetitive phenomena which are, to some extent, general. In this article, we look at how cases are treated in biographical sociology. We present our own empirical experience, consisting in autobiographical narrative interviews with participants of a nationwide panel survey, who were randomly drawn to the panel many years ago. We show the possible consequences, both methodological and theoretical, of this way of selecting cases, quite unusual for biographical sociology. We wonder whether and to what extent the experience of the “ordinary person,” the Everyman, can be reflected in sociological works based on the biographical method.
Socjologiczne jakościowe badania biograficzne wyróżnia zainteresowanie przypadkiem. Jednocześnie dąży się w nich – często za pośrednictwem studium przypadku – do zrozumienia lub wyjaśnienia zjawisk ponadindywidualnych, powtarzalnych, do pewnego stopnia ogólnych. W artykule przyglądamy się sposobowi traktowania przypadków w socjologii biograficznej. Przedstawiamy własne doświadczenia empiryczne, polegające na przeprowadzeniu autobiograficznych wywiadów narracyjnych z uczestnikami ogólnopolskiego, panelowego badania surveyowego, którzy zostali do niego przed laty wylosowani. Pokazujemy, jakie konsekwencje – metodologiczne i teoretyczne – może mieć taki, nietypowy dla socjologii biograficznej, sposób doboru przypadków. Zastanawiamy się, czy i do jakiego stopnia doświadczenie „zwykłego człowieka”, everymana, może zostać odzwierciedlone w pracach socjologicznych opartych na metodzie biograficznej.

Opis:
In recent years, container ships have had to transport more and more goods due to constantly growing demand. Therefore, the container ships for carrying these goods are growing in size, while the harbors fall short in adapting to these changes. As a result, the berthing of these container ships in harbors has become more challenging for harbor pilots. In this work, we identify problems and risks with which pilots are confronted during the berthing process. First, we analyzed approximately 1500 accident reports from six different transportation safety authorities and identified their major causes. Second, we conducted an ethnographic study with harbor pilots in Hamburg to observe their actions. Third, we gained more specific insights on pilots environments and communications through an online survey of 30 harbor pilots from different European countries. We conclude our work with recommendations on how to reduce problems and risks during berthing of container vessels.

Objective: to evaluate knowledge about phytoestrogens among Polish menopausal women, and to assess their applicability and safety. Methods: The study included 300 women from the Wielkopolska Region, aged 40-60 years. The questionnaire was designed especially for the study. Crosstabulation tables and Perason’s chi-squared test was used for the statistical analysis. Results: 147 respondents continued to menstruate. Hormone Replacement Therapy was used by 69 subjects; 114 respondents, used phytoestrogens. The place of inhabitance influenced the reasons for not using phytoestrogens. Media, healthcare providers and personnel were the main source of information about phytoestrogens. Most of respondents perceived phytoestrogens as substances displaying a beneficial effect on health. 69% of the subjects reported positive effects of non-hormonal preparations for the relief of climacteric symptoms, mainly reduction in hot flushes and alleviation of joint pain. Conclusions: Our results support the postulate of efficacy and safety of phytoestrogen use to relieve climacteric symptoms. Both education and place of inhabitance appear to affect the opinions of the affected females about phytoestrogen use during menopause.

Objectives The development of allergic conditions is largely dependent on the interactions between genetic (individual genetic predisposition) and environmental factors (exposure to risk factors). The aim of this study was an attempt to assess the influence of selected elements of the hygiene theory in the development of allergic diseases such as allergic rhinitis and asthma. Material and Methods The study group consisted of 5518 women and 3868 men. The method that was used was the European Community Respiratory Health Survey II and International Study of Asthma and Allergies in Childhood questionnaire validated and adapted to Central and Eastern European conditions. The project was conducted in 8 urban areas (Gdańsk, Wrocław, Poznań, Katowice, Kraków, Lublin, Białystok, Warsaw) and 1 rural area (Krasnystaw county). This study had 2 stages; the first stage involved grouping the 22 500 respondents based on their questionnaire responses with the use of a Personal Digital Assistant (PDA); the second stage involved 7000 subjects, who underwent additional assessments: skin prick tests (birch, grasses/cereals, Dermatophagoides pteronyssinus and Dermatophagoides farinae, molds [set I: Botrytis cinerea, Cladosporium herbarum, Alternaria tenuis, Curvularia lunata, Fusarium moniliforme, Helminthosporium], molds [set II: Aspergillus fumigatus, Mucor mucedo, Penicillium notatum, Pullularia pullulans, Rhizopus nigricans, Serpula lacrymans], cat, dog, molds Cladosporium herbarum, Alternaria tenuis) and spirometry tests. Results The age at which children attend the nursery school is critical to the development of allergic diseases; in allergic rhinitis, the risk of an IgE-dependent reaction is 2 times higher in the second than in the first year of life (p = 0.00147, p < 0.05), while in asthma, having a large number of siblings increases the risk of developing obstructive disease by almost 6 times (p = 0.00316, p < 0.05).The age at which children attend the nursery school is critical to the development of allergic diseases; in allergic rhinitis, the risk of an IgE-dependent reaction is 2 times higher in the second than in the first year of life (p = 0.00147, p < 0.05), while in asthma, having a large number of siblings increases the risk of developing obstructive disease by almost 6 times (p = 0.00316, p < 0.05).

The problem of municipal waste management is one of the greatest challenges of the 21st century. Its solution requires the integrated involvement of central and local authorities as well as the public. For their actions to be fully effective, they must be accompanied by an increase in environmental awareness. The aim of the study was to assess the environmental awareness and knowledge of inhabitants of eastern Mazovia regarding municipal waste management. A survey study was carried out on a group of 262 individuals using a questionnaire. Analysis of the results showed that the surveyed inhabitants of eastern Mazovia were aware of problems associated with municipal waste management, but some of them were critical of the actions taken by central and municipal authorities to solve them. Their high level of environmental awareness and knowledge was evidenced by the fact that most of those surveyed were familiar with the principles of selective collection of municipal waste, including green and hazardous waste.

Opis:
The aim of a sample survey is to obtain high quality estimates of population parameters with low cost. The expected precision of estimates and the expected data collection cost are usually unknown making the choice of sampling design a complicated task. Analytical methods can not be used often because of the complexity of the sampling design or data collection process. The aim of this paper is to develop a mathematical framework to compare chosen sampling designs with respect to the expected precision of estimates and the data collection cost. As a result a framework is developed which employs artificial population data generation, survey sampling techniques, survey cost modelling, Monte Carlo simulation experiments and other techniques. The framework is applied to analyse the cost efficiency of the sampling design currently used for the Latvian Labour Force Survey.
