Opis:
The observed collapse of demographic pyramid increases the tension on the social security systems, especially pensions. It implies a requirement to extend the retirement age. On the basis of Eurobarometer 65.1 we calculate difference between expected and preferred retirement age in Poland. Then we show the determinants of individual differences. Particular attention is paid to the problem of non-random missing observations.

Opis:
Varistors are commonly used elements which protect power supply networks against high-voltage surges or lightning. Therefore, quality and endurance of these elements is important to avoid losses when an expensive laboratory equipment would not be protected from random overvoltages. Additionally, excessive leakage currents generate serious costs due to high energy consumption. The paper presents shortly properties of varistors that comprized different ZnO grain types and can have various quality which changes continuously during exploitation (due to exposition to overheating and overvoltage pulses). Therefore, it is important to monitor varistors during their ageing (causing changes within their microstructures). A few methods of varistor property diagnosis were considered and compared with the methods currently applied in laboratory or industry applications. A new measurement (diagnostic) system that can monitor varistors during ageing and can be widely applied in power networks is presented. The proposed system fulfills requirements of the industrial customers which demand various methods for power line protection. The proposed system can be simply developed into a more advanced wireless diagnostic system of long power supply lines.

Opis:
Because of the growing operational age of nuclear power plants, the ageing management of structures, systems and components used in these plants is gaining an important role. Technical systems are subject to timedependent and operationally caused ageing phenomena with modifications of originally given characteristics and, thus, of relevance in terms of safety. Especially physical ageing is of importance. Therefore, a comprehensive ageing management is required. In the context of an integrated safety management it has to be shown how to integrate the safety related issues of ageing into probabilistic safety assessment (PSA). In particular the question is to be answered whether the effort for the execution of an ageing PSA is justified, in particular if the safety significant effects of ageing can be identified and quantitatively estimated. Method for prioritization of the components in the nuclear power plant considering implication of their ageing on safety of the nuclear power plant is presented. On the basis of an actual report on ageing management in German nuclear power plants and a literature survey, this paper tries to estimate the necessity and value for the introduction of an ageing PSA in Germany.

Opis:
Demographic changes seen in Europe represent the challenge for social protection system and for the job market. In most countries of European Union we can see a clear tendency to increase retirement age. In our country breaking the reluctance towards the attempts of increasing retirement age appears to be difficult, and only a small percentage of employees decide to continue their professional career after coming to retirement age. The aim of research was to deepen the diagnosis concerning the phenomenon of low professional activity of women being at retirement age by looking into intergeneration differenc- es. Results shows negative attitude to the idea of professional activity in the old age, which is motivated mainly by health problems, labor market conditions and women’s double burden.

Opis:
The aim of this study was to assess handgrip and 5 other types of force in 52 women and to determine if handgrip force reflected general upper limb force capabilities correlated with age. The women were divided into subgroups according to age: 20–25, 45–50 and 55–65 years. Maximum forces of the right upper limb were measured in 6 types of force activities. In most tests the values of force showed statistically significant differences between the 20–25 group and the groups aged 45–50 and 55–64 years. The results did not show any differences related to age or to force activities that involved the small muscles of the forearms and hands. Thus handgrip force cannot always be considered an indicator of total force capabilities.

Opis:
The aim of this paper is to make a quick overview of the literature concerning not only the variety of concepts of ageing and activities that older people may take in their free-time, but also the significance of intergenerational family relationships, especially the grandparents-grandchildren relationship. On this background authors’ own research on this topic is presented. The obtained results confirmed the hypothesis that younger grandparents are more vital and have more free-time activities than the older. Moreover, the findings indicate the importance of role that grandparents may play in grandchildren’s life (‘stabilizer’, ‘family national guard’, ‘arbiter’, ‘historian’) regardless of their age. It is also shown that with increasing age and declining social networks grows the need to maintain close contact with younger generations of the family.

Opis:
Introduction. The ageing society of Poland still experiences health-related problems and increasing difficulties in receiving medical care. The initiation of telemedicine programmes can change this situation for the better. The question arises whether telemedicine is a solution that the elderly are willing to accept and take advantage of in order to raise their quality of life. Objective. The aim of the research was an investigation of the quality of life and the course of ageing among the elderly Polish population, and their openness to the notion of telemedical services. Materials and method. A questionnaire-based study was conducted in 2015 on a sample group of 312 seniors. The respondents completed the Diener Satisfaction with Life Scale (SWLS) and the subscale of Health States from Fragebogen zur Lebenszufriedenheit (FLZ) by Fahrenberg et al. Each participant gave consent to take part in the research. Results. SWLS presents a relatively stable value in the subsequent decades of old age (60–69 years, M=21.93, SD=6.25; 70–79 years, M=21.70, SD=5.52; 80+yeasrs, M=21.38, SD=5.82). The health related quality of life (the FLZ subscale) varied in the analysed subgroups (F=7.783: p=0.000) and was related to comorbidity and polytherapy. A positive attitude towards telemedicine was expressed by 40% of those surveyed. However, the need of the seniors for telemedicalservices was limited and did not exceed the 10%. Conclusions. In Poland, in ageing there still dominates the experience of multiple ailments and polytherapy, something which justifies a search for new, easily accessible, and economically sound solutions for health care. Telemedicine is a promising solution, although there is a need for definite steps to be taken to increase the willingness among geriatric patients to take advantage of telemedicine.

Opis:
Basic notions of the ageing multistate systems safety analysis are introduced. The system components and the system multistate safety functions are defined. The mean values and variances of the multistate systems lifetimes in the safety state subsets and the mean values of their lifetimes in the particular safety states are defined. The multi-state system risk function and the moment of exceeding by the system the critical safety state are introduced. The exemplary safety structures of the multistate systems with ageing components are defined and their safety functions are determined. As a particular case, the safety functions of the considered multistate systems composed of components having exponential safety functions are determined. Applications of the proposed multistate system safety models to the evaluation and prediction of the safty characteristics of the exemplary series, parallel, “m out of n”, consecutive “m out of n: F”, series-parallel, parallel-series and “m out of l”-series systems are presented as well.

Competencies are a crucial factor of professional position and career development. The aim of this paper is the assessment of the competencies of people in late productive age using exploratory factor analysis. The second point is the critical review of the theory and practice on exploratory factor analysis. The empirical analysis is based on the Study of Human Capital data. The survey results confirm the necessity of the factor analysis in research in the area of human capital in the context of ageing. The constructed synthetic indicators allowed for a synthetic assessment of the competencies of Poles aged 50-59/64. The results of the conducted analysis confirm the large significance of all the 24 analysed competencies. The competencies of Poles aged 50-59/64 were decomposed into three groups: (1) soft competencies and physical fitness (2) computer skills and (3) availability and technical competencies.

Opis:
The results of investigations on the microstructure of T23 and T24 low-alloy steels as well as P91 and P92 high-chromium steels in the as-received condition and after 70.000 h annealing at 550-650°C are presented. The quantitative analysis of the existing precipitates was performed for representative images of microstructure. The statistical analysis of collected data allowed the parameters of a selected theoretical statistical distribution to be estimated. A forecast of average precipitate diameter and standard deviation of such a distribution for the time of 100,000 hours at 550 and 600°C for T23 and T24 steels and at 600 and 650°C for P91 and P92 steels was calculated. The obtained results of investigations have made it possible to compare changes in the microstructure of various steel grades due to long-term impact of elevated temperature. They have also confirmed the possibility of using, in evaluating the degradation degree of materials in use, the forecasting methods that derive from mathematical statistics, in particular the theory of stochastic processes and forecast by analogy methods. The presented approach allows the development of a forecast of precipitate diameter probability density under the microstructure instability conditions for selected steel grades. The assessment of material condition that takes into consideration, but is not limited to, the precipitate diameter measurement is useful as an assessment component in estimating the time of safe service of power unit elements working under creep conditions.

Opis:
The aging of population is largely caused by falling fertility. To find out how fertility affects the share of the elderly people in the population, four variants of the UN World Population Prospects 2010 for Poland and Europe were examined, as well as selected indicators of population aging. The relatively high fertility and comparatively short life expectancy in Poland until the end of 1980s explain why its population aged much more slowly than other populations in Europe. In the last two decades the share of the elderly people kept increasing, mostly because of the deep decline in the number of births. For almost a decade now Poland has been one of the demographically old countries, although the aging process is relatively less pronounced in Poland than in Italy or Germany. In the medium variant of the UN forecast Polish fertility will be growing for the next few decades, but its level will not be high enough to ensure the minimum population replacement. Only in the high variant its growth will lead to rates of population reproduction higher than the minimum level. This situation might take place as early as the first half of the 2020s. The analysis of particular indicators illustrating the progress of demographic aging leads to a conclusion that even high fertility will not rejuvenate the age structure of Polish population, but it may considerably slow down the process of its aging.

The article focuses on healthy longevity. The starting point is the assumption that a long and healthy life, much as it is genetically– and environmentally-dependent, is likewise related to one’s lifestyle. The text tries to indicate which elements of the lifestyle contribute to healthy longevity. To this end, the article reviews approaches and theoretical concepts on healthy ageing and provides empirical data gathered in longevity zones worldwide, called the Blue Zones by National Geographic researchers. Analysis confirmedK. Wisniewska-Roszkowska’s observations that a long and healthy life depends on a proper diet, physical activity and care for mental health. The author has suggested that the obe-sity index should be an indicator of ageing pathology.

Opis:
The ageing of societies has recently become one the most important phenomena shaping social policy in Poland and other developed countries. At the same time, it is becoming increasingly clear that ageing should not be perceived only in terms of threats. Silver economy, age management, and lifelong learning are the notions that become acknowledged by various labour market and social policy stakeholders. The rationale behind these ideas is to make the best use of the potential of people around the retirement, in line with the life cycle concept, but also of new social needs that arise with an increasing proportion of people aged 50+ in the society, and with considerably improving quality of their lives. The discussion presented in the article is limited to problems in extending working life of Poles. The aim of this paper is analysis of the factors influencing the extension of the working life in Poland, from an individual perspective, i.e. by looking at the reasons of individual decisions of people close to the retirement age. The article is both theoretical and empirical in nature, presenting a review of studies including the support for the economic activity of “older” workers, coupled with the outcomes of a statistical analysis carried out in the project „Equal opportunities in the labour market for people aged 50+”.
