The Impact

Noise can have many harmful effects on the recipients, however people exposed to noise on a long-term and regular basis can get used to it, even if the permissible levels are exceeded. In cities, green areas and park systems are provided to create a climate for rest and relaxation. Spa parks are a special kind of such park systems, which – in addition to the above-mentioned features – support therapies offered by spa facilities located there. On the one hand, patients and visitors appreciate various social and entertainment events held there, but – on the other – a multitude of sounds associated with them may reduce the comfort of their stay. The aim of this paper is to analyse the relationship between the results of noise measurements and the human perception of noise within the impact zone. The examined area is a spa park in the health resort district of Inowrocław, where seasonal measurements (taken in summer and winter) provided a basis for the determination of the connection between the measured values of equivalent sound level and the noise level perceived by surveyed people. A statistical analysis was performed to take into account the correlation between the obtained measurement results and the human perception of noise. It shows some differences in the perception of heard sounds. The results allow an evaluation of the soundscape of the analysed area.

Pig Husbandry

The widely fluctuating operating conditions in pig husbandry, due to climatic and biological changes (changes in temperature and air flowrate between day and night, as well as between summer and winter, increasing animal mass during the fattening process, etc.) exert a significant influence on the amount of actual odour emission. The project presented here comprised the measurement of seasonal (fattening course), daytime-related, and short-term (feeding) dynamic effects of odour release, as well as the identification of potential factors which influence the amount of odour emitted. In parallel with “classic” olfactometry, an electronic odour sensor with a chemosensor array of ten metal oxide sensors was employed. The highest odour emissions are measured on hot summer days, while the lowest emissions were determined on cold winter days. On the one hand, the sensor signals of the electronic odour sensor exhibited considerable differences on days with large volume flow alterations. On the other hand, continuous measurement with the electronic odour sensor allowed changes in the gas- and odorant composition of the exhaust air during feeding times to be shown. From the measurement results, recommendations for odour sampling, the consideration of seasonal odour emission fluctuations, and the use of electronic odour sensors for the evaluation of odour emissions have been derived.

The Impact

This paper presents results of an ongoing project which aims to develop a purpose-built platform for using smart phones as alternative to sound level meters for citizen-science based environment noise assessment. In order to manage and control environmental noise effectively, the extent of the problem must first be quantified. Across the world, strategic noise maps are used to assess the impact of environmental noise in cities. Traditionally, these maps are developed using predictive techniques, but some authors have advocated the use of noise measurements to develop more reliable and robust noise maps. If adopted correctly, smartphones have the capability to revolutionize the manner in which environmental noise assessments are performed. The development of smartphone technology, and its impact on environmental noise studies, has recently begun to receive attention in the academic literature. Recent research has assessed the capability of existing smartphone applications (apps) to be utilized as an alternative low-cost solution to traditional noise monitoring. Results show that the accuracy of current noise measurement apps varies widely relative to pre-specified reference levels. The high degree of measurement variability associated with such apps renders their robustness questionable in their current state. Further work is required to assess how smartphones with mobile apps may be used in the field and what limitations may be associated with their use. To over come the above issues, this project is developing a platform specifically for citizen science noise assessment. The platform consists of a smartphone app that acquires a sound signal and transfers the data to a server via a web based API for post processing purposes. This then returns key information to the user, as well as logging the data for use in a massive noise mapping study. The structure of the proposed platform maintains a clear separation between client (phone) and server. This approach will allow implementation of future open source client side apps for both Android and iOS operating systems.

The article presents results of the evaluation of urban noise levels from the road transport. Over the period 2012-2016 there was recorded an annual gain in the proportion of results of noise measurements failing to meet standards. In the daytime, evening and night time in residential areas of the city there are systematically recorded excesses of maximum permissible levels of equivalent and maximum sound levels. The highest levels of sound were recorded during the daytime: the equivalent sound level reaches 81 dBA, maximum sound level - 94 dBA. The impact of the noise of this level on the human body is characterized by a high likelihood of the development of non-specific effects (up to 0.98 units) and is evaluated as most high level. The probability (risk) for the making complaints by residents amounts up to 0.75 units (an extremely dangerous risk level), the development of hearing loss - 0.17 units (risk causing fear). High health risk indices from the impact of transport noise were established to be characteristic of cardiovascular diseases. In particular, as the age (probable duration of the exposure time) increases from 30 to 50 years, the level of risk is estimated as average (the risk ranges from 0.08 to 0.34 units), from 55 to 65 years - as high (from 0, 36 to 0.59), from 70 to 85 - as extreme (from 0.68 to 1.00). Theoretically there were substantiated measures for noise protection in the urban environment, including the architectural and planning techniques to protect the population from the traffic noise.

The paper presents the results of measurements for one hundred and ten scaffolds located in five cities in different parts of Poland. Measurements were made between April of 2016 and October of 2017. The environmental tests performed on scaffoldings were focused mainly on the sound level. The parameters on which we base our analysis are the value of C-weighted peak sound levels and daily noise exposure level. The noise that affects construction workers on scaffolding may influence the behaviour of workers and increase the risk of accidents. And at the same time, noise exposure laws facilitate identification of high noise-emitting activities and provide effective preventive measures that reduce noise pollution and improve work environments. The analyses carried out confirmed the qualitatively expected dependencies, and allowed us to quantify the impact of noise to which scaffolding workers are exposed. In summary, noise measurements on scaffoldings can be a valuable aid in improving working conditions. The analysis of research results allows understanding hazards related to noise in an accessible way. They provide the opportunity to modify the professional environment so that it is more employee-friendly and does not expose them to problems occurring in a noisy work environment.

Introduction. UNESCOs adoption of the Convention “Concerning the Protection of the World Cultural and Natural Heritage” of 1972 led to the discussion on the issues of mutual influence and interdependence of humankind and nature and human perception of the environment and his own ecological niche. As a result of these discussions, the term “cultural landscape” came into use, and became part of the world cultural heritage. Methods and materials. This study is based on the combination of the general, special historical and cultural methods. The central place among them was occupied by the comparative, analytical, historical-genetic, comparative analysis methods and some methods of historical cultural studies. Analysis. The evolution of the cultural landscape took place throughout human history and is a unique blend of not only human development. It also reflects, on the one hand, national culture and mentality, and on the other, shows the influence of natural factors on their development. It also helps to understand the mentality of various ethnic groups, similarities and differences in their perception of the world and attitude. The development of the cultural landscape concept has become an integral part of the Anthropocene theory, based on the teachings of V.I. Vernadsky, about the impact and intersection of the geo-, bio- and noosphere in the fate of humankind. Results. The article considers the development of the “cultural landscape” theory mainly in English and American historiography which conclusively demonstrates how natural factors impact on changes in culture of the same ethnos. Through historiographic studies and comparisons, it becomes possible to trace the importance of preserving and studying the cultural landscapes of the past and present, in order to understand ourselves and be responsible to the world around us.

In this work, an experimental study about the hydrodynamic tonal noise in an industrial centrifugal pump with seven blades has been carried out. Noise measurements on the casing surface have been made for different flow rates with constant shaft speed. The experiment explains that in the frequency domain, the noise of centrifugal pump can be categorized in to two parts. First, as was expected, those frequencies which sound level of them is related to the flow rate and second, those ones that the sound level of them is constant and related to the pump structure. The experiment determines that the frequencies at the second type are so few, and they have correlation with BPF fluctuations. Also with deep notification, it can be considered that these special frequencies, lead or lag due to the speed fluctuations which produced by flow rate changes in nearly constant shaft speed.

In this paper, we propose to assess the efficiency scoretechniques of 10 Tunisian commercial banks for the period cover 1990 to 2018. The local banking landscape was marked, during the period studied, by significant changes following the adoption by the Tunisian government, of various financial liberalization measures as well as the period of the subprime crisis and then the revolution of 2011. Given studying the technical efficiency levels achieved by Tunisian commercial banks, we propose a non-parametric method, the approach DEA, data envelopment analysis, on the one hand, and the determination of the variables explaining the level of performance on the other. Our results allow us to conclude that the banks which obtained the best average efficiency scores are: Amen Bank (100%) and Arab Tunisian Bank (98.9%). Whereas, other banks are considered inefficient. To study the impact of banking performance indicators, a variable that measures the crisis, Equity, total assets, and total liabilities on the efficiency scores calculated by the DEA methodology, return on assets (ROA) and return on equity (ROE), we used an ECM error correction model in panel data. The results show the positive impacts of these indicators on banking performance in Tunisia.

The Impact

For the determination of characteristics of LQ ofpatients with cystic fibrosis (CF) and evaluation of the efficacy of the management there was used Health Utilities Index (HUI) questionnaire. The study involved 99 CF patients at the age of from 5 to 18 years. The comparison group - 102 conditionally healthy peers of the same age. All children underwent to a comprehensive medical examination and treatment. LQ assessment was carried with the aid of the HUI questionnaire. CF patients were found to have a significant decline in overall LQ in 84,8% of cases in comparison with their healthy peers. Analysis of the «way of life cohort» showed the fall in multiattribute utility indices in children at the age of 6.12 and 16 years. There was also noted a pronounced decline of indices on attributes: «pain» in 55,6%, «emotions» - in 65,6% and the «self-care» - in 20,2% of cases. Factors significantly affecting on LQ of CF patients were established to be: the presence of homozygous or heterozygous delta F508 mutation, disturbances of the respiratory function and malnutrition, which contributed to a decrease as in the overall index as well in specific aspects of LQ. Against the background of the management during the one hospitalization there was noted the positive dynamics due to the gain in the index of the emotional background. A similar situation was revealed after 6 months in re-hospitalization. Pronounced positive dynamics was noted after the management of patients with severe course of the disease, the worst values of radiological indices and a decline in FEV1 indices. The authors believe the study of LQ of CF patients to be important not only for the evaluation of the impact of the disease on the patient’s LQ, but also for the determination of the efficacy of the management.
