Towards Smart City: Influence of Air Pollution on the Local Community of the Zabrze City in Surveys and Field Research

Abstract

The results of the conducted pilot research indicated the basic local problems of the residents of Zabrze city. The purpose of the next research was to answer the question: how to improve the quality of life of residents in a city with significant air pollution. Activities aimed at this goal are inscribed in the idea of "smart city". The article presents the results of pilot measurements of air pollution with toxic gases in the Zabrze city in the Silesian agglomeration (Poland). Field studies at selected locations in the city concerned measurements of nitrogen dioxide, sulphur dioxide and carbon dioxide. The aim of these studies was to identify areas of the city with significant air pollution with toxic gases in order to plan further detailed research. Made measurements showed the appearance of the local problem of accumulation of pollutants in several areas of the city. The results obtained were compared with surveys conducted among residents of the Zabrze city. The aim of the survey was to examine the respondents' awareness of: the location of areas with noticeable air pollution and health problems resulting from air pollution in the place of residence. The article also presents a plan of possible actions for the city of Zabrze within the framework of the "smart city" idea to improve the quality of life of the local city community in conditions of increased emission of gas pollution in the city.

Technology for Intensive Poultry Production as a Source of Odour Emissions with Time-Varying Intensity

Abstract

The technology for intensive broiler breeding using deep litter method provides convenient conditions for production of odour substances inside the barn. As a consequence, there are relatively high odour emissions in the breeding area and its surrounding, which has significant impacts on the life quality of both people and animals. The amount of produced emissions increases in time because it is closely related to the amount of poultry droppings accumulated in litter inside the barn. This paper deals with changes in odour intensity depending on time measured since the beginning of broiler fattening. Odour intensity was measured by methods of dynamic olfactometry. The estimated values gradually increased from 45 ouE·m-3 to the highest value of 259 ouE·m-3, which was determined in the final fattening phase (broilers’ age 33 days). The calculated odour substances emission values were in range from 0.02 ouE·s-1·bird-1 at the beginning of fattening up to 0.10 ouE·s-1·bird-1 in the final fattening phase. Odour emissions increased five times during the fattening period.

Designing Functional Clothes for Persons with Locomotor Disabilities

Abstract

The life quality improvement issue is a problem of national and international interest. This acquires total different values when it is to refer to a series of disadvantaged categories, that is the persons with locomotor disabilities. It is an inevitable social responsibility to create equal opportunities for disabled people, to prevent any intentional or unintentional discrimination that they face and apply positive discrimination if necessary to improve their living standards and to let them have an equal share from social development as productive individuals of society.

A disability is any kind of restriction or inability to accomplish a certain activity, which belongs to the interval considered as “normal” for a human being. Disabilities are characterized by deficiencies or excesses in the activity or behaviour that is normally expected from a person; they can be temporary or permanent, reversible or irreversible, progressive or regressive. The physical disabilities that require the use of wheelchairs imply the manufacturing of special clothing products that meet certain needs at a functional and/or therapeutic level.

The study presents the main aspects involved in designing and developing textile products for this category of users. Therefore, the apparel that is specially designed for persons with disabilities has to: allow more freedom and independence when is being worn, correspond to the aesthetic point of view, offer psychological benefits and help to socially integrate the individual who wears it. In addition, clothes should not hinder the individual’s mobility and must allow the use of the chest and of the superior limbs to the maximum, they must be durable, have a low level of electrostatic charge, be absorbent and comfortable, present the so-called “rehabilitation functions”, and last but not least, be beneficial for the wearer both from a physical and psychological point of view.

The Manufacturing of Textile Products with Incorporated Electrodes

Abstract

One of the main causes of disabling deficits is neurological affections. Many times, the evolution of the condition leads to a diminution of the patient’s life quality. Functional electrical stimulation (FES) is part of the neurological rehabilitation process that comprises all the actions one can take in order to increase a patient’s integration and autonomy degree from a social and financial point of view. FES is a method based on substituting the commands that are usually transmitted by the nervous system with an electric impulse. The use of such a method on different body areas required the development of some adequate devices, starting with the stimulator itself and finishing with the way in which the stimulus is conveyed to the effectors. Textile materials that incorporate sensors and, mainly, the clothing products that have such components in their structure, have a high applicability potential; they can be used for preventing illnesses and for the rehabilitation of seniors, of people who are confined to bed, sportsmen, people who suffer from long-term illnesses, disabled people, thus diminishing the time one spends in the hospital. A possible solution for manufacturing incorporated textile electrodes consists in the insertion of some electro-conductive yarns onto textile surfaces by using a variety of technologies. The project approaches the use of knitting, a widespread textile technology. The incorporated knitted electrodes were accomplished by applying the knitting technology on single circular small diameter machines. Thus, we were able to obtain a variety of knitted articles as two-dimensional or three-dimensional tubular knitted fabric. Their dimensions, structures, and parameters correspond to the typo-dimensions of the human body and to the purpose for which the clothing product was designed. The knitted versions were tested by using a Microstim2v2 (PW = 300 μs, 40 Hz) neurostimulator for which the current intensity was adjusted to approx. 30 mA.

Operationalising Responsible Research and Innovation – tools for enterprises

Introduction Technological progress and radical innovation carry promise of a higher life quality but at the same time are inseparably connected with risks and uncertainties. Many inventions also raise critical ethical issues. Genetically modified organisms (including food), vaccinations (especially for children), shale gas drilling, gene editing, mass surveillance, nanotechnologies, robotics, brain-machine interface – these are just examples of controversial topics where hopes and fears collide in society. Supporters and opponents of particular scientific
