Opis:
Telecommunication networks are ever more frequently relying on artificial intelligence and machine learning techniques to detect specific use patterns or potential errors and to take automated decisions when these are encountered. This concept requires that methods be employed to measure the level of quality of a given telecommunication service, i.e. to verify quality of service (QoS) metrics. In a broader context, methods assessing the entire user experience (quality of experience – QoE) are required as well. In this article, various approaches to assessing QoS, QoE and the related metrics are presented, with a view to implement these at an FTTH network operator in Poland. Since this article presents the architecture of the system used to analyze QoE performance based on a number of QoS metrics collected by the operator, we also provide a comprehensive introduction to the QoS and QoE metrics used herein.

Opis:
Interest in “quality of life” issues originated in the 1950s. The concept found applications in fields such as economics, social policy, medicine, sociology and psychology. Quality of life could perhaps also be an object of study for security sciences as well. Despite the continued popularity of this category, social scientists are yet to develop a commonly agreed upon definition of the concept. This paper constitutes an attempt at answering the question of whether the need for security is related to quality of life and whether it is valid to introduce a new conceptual category in the form of quality of life security. If so, then it is necessary to determine whether it is a measure that is subjective or objective. Human needs such as security and quality of life are what motivates human actions and activity. If one of the above needs is not being met, the individual become destabilised. The homogenisation and standardisation of scientific concepts would render it possible to compare data from an interdisciplinary point of view.

Opis:
This article presents the issues of quality research and improvement of logistics processes in the area of distribution of one of selected industrial enterprises. The case described concerns the producer of raw chemical materials, who acts as a supplier for industrial customers. The studied company, due to dynamic changes in product demand, very often outsources the distribution of raw materials to external transport companies. This solution results in limited supervision over commissioned processes, which may lead to increased probability of customer dissatisfaction. The article presents the results of the study of the quality of logistic processes implemented or commissioned in the examined enterprise. The assessment was based on the results of the customer satisfaction survey and the results of the analysis of received complaints regarding deliveries. Analysis of the causes of complaints allowed to identify the actions necessary to improve the quality of logistics processes. This article contains, among others, the criteria for the assessment of transport service providers and a set of recommendations to reduce the risks associated with logistics processes of deliveries.

Introduction: Profound hearing loss significantly affects the quality of life of deaf people as well as their families. Observation of the benefit from the use of cochlear implants in deaf patients allows to assess the success of treatment with this method and its impact on the quality of life of these patients. The aim of this study was to determine the quality of life in patient after the cochlear implantation in the material of Department of Phoniatrics and Audiology of the Medical University in Poznań. Material and methods: The study involved implanted patients who voluntarily joined to the project entitled "Observational study of the implanted patient (Cochlear-IROS)". It has a prospective character, it is an international and long-term study, covering the observation of patients up to three years after implantation. Standardized HUI and SSQ questionnaires were used. 70 patients were included in the analysis, the mean age at the time of the cochlear implantation was 47.6 years. In the research group there were 33 men and 37 women. In the whole group, the patients' age at implantation was at least 18 years, max. 80 years. Results: The results of the SSQ questionnaire, which deals with the self-assessment of hearing ability in everyday situations, indicate that in the subjective assessment of patients one year after surgery the speech hearing improved by 77%, spatial hearing by 84%, and the quality of hearing by 49%. The general quality of life before the first connection of the sound processor according to the HUI questionnaire, the patients rated at 0.49 (0-1 scale, where 0 - corresponds to the death condition and 1 - full health). After one year from the implantation, this rating increased to 0.56. Conclusions: The implantation of the cochlear implant significantly increases the patient's quality of life, its physical and emotional functioning. Statistically significant better self-assessment of patients mainly concerned hearing speech and spatial hearing - especially after 1 year of connecting the speech processor.

Opis:
Having a home has been cited as a principal good, both in economic and social terms. It plays a key role in human life. Having a home often determines other decisions, such as getting married, starting a family, and changing jobs. Research papers dealing with the question of home ownership or tenancy, as well as various publications issued by the government and non-government organisations, emphasise the problem of a housing deficit. However, the question of the quality of housing resources is raised less often. Living conditions are one of the research areas investigated in studies concerning the quality of life. The purpose of this article is to assess the quality of Poland’s housing resources at the regional level, using data from 2003 and 2016 and aided by Perkal’s synthetic indicator. According to this indicator, the Mazowieckie Voivodeship had the highest value (0.849), and the Warmińsko-Mazurskie Voivodeship the lowest one (-0.722).

Opis:
The concept of the quality of consumer products and services is fairly well defined. Although today quality of life, including quality of education and training, is a commonly discussed topic, one has to admit that the evaluation system of educational processes and the quality of work of educational institutions is surprisingly low. At the same time, the modernization processes in the system of universities forces basing development decisions , including funding, on achieved indicators of work effects of universities. Existing, domestic and international, external and internal quality assurance systems of university work have been criticized for arbitrariness, unilateralism (eg. the criteria exclusively on the results of teaching, or solely on the results of research), ambiguity of the methodology, unreliability of sources of used data, etc. This means that further inquiry to identify their strengths and weaknesses as well as the directions of their consolidation in the complex policy tool for scientific, educational and social decisions is necessary.

Opis:
TQM is a term associated mainly with ensuring the quality of production, where the emphasis is on quality in all parts of the production process. The introduction of TQM into the operation of a service company therefore seems to be more difficult. In the presented article we address the basic requirements for the introduction of TQM in a company providing road freight transport. The basic PDCA approach needs to be implemented in all processes of the actors involved in the supply chain. The article points out the fact that evaluating the quality of the provided service only on the basis of a single indicator, which is the monitoring of the number of complaints and claims, is not sufficient as evidence of the established TQM system. The customer requires evidence of long-term and serious monitoring. As part of this monitoring, it proposes the creation of an effective evaluation system for evaluating the quality of the external service provider. To determine the priority requirements of the customer, it is appropriate to apply several known simple evaluation methods. In the article, we applied the pairwise comparison method and the Saaty’s method to determine the order of importance of the quality criteria that we previously found in the customer survey: integrity of the consignment, compliance with the agreed delivery time and completeness of the shipment, including documents. We therefore recommend focusing on these criteria when providing TQM in the company.

Opis:
Mobile systems, by nature, have finite resources. Radio spectrum is limited, expensive and shared between many users and services. Mobile broadband networks must support multiple applications of voice, video and data on a single IP-based infrastructure. These converged services each have unique traffic holding and quality requirements. A positive user experience must be obtained through efficient partitioning of the available wireless network resources. The 3rd Generation Partnership Project (3GPP) has developed a comprehensive Quality of Service (QoS) parameter to address this problem. The regular control of service quality is critical for operators to ensure user Quality of Experience (QoE), establish new business models and monetize services. It enables operators to employ fair-use resource policies and maintain network performance during peak traffic times. Wireless mobile communication is tending towards an integrated system of Internet and telecommunication technologies, where mobile users move freely anytime and everywhere. They desire to communicate with any device using the best service available. In this paper QoS management issues in mobile communication are described. The authors present an insight into subscriber behavior and related factors that affect the QoE of mobile data services.

Opis:
The COVID-19 pandemic has significantly limited user mobility, not least among students. Remote learning had a particular impact on resource allocation in relation to using terrestrial cellular networks, especially 4G systems in urban agglomerations. This paper presents the results of a quality evaluation of an outdoor environment, carried out between 2019 and 2021 on the campus of a technical university. Annual studies are conducted using our own custom-built mobile application, installed on 50 mobile devices (i.e., smartphones) running Android OS. This study aims to determine the impact of reduced user mobility on access parameters in mobile networks, that is, both download and upload throughput as well as delay (ping), with a particular focus on serving base transceiver stations (BTSs). This research scenario involves long-term evolution (LTE) compatible user equipment (UE) that operates under four Polish mobile network operators (MNO), which includes roaming connections and the newly launched 5G standard.
