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.

Objectives: The main goals of this study were to assess the most significant morphological changes and acoustic measures for the ageing process of a professional opera singer’s voice. Design: This investigation included 58 healthy professional opera singers, who were compared with 42 young opera singers from the control group. Methods: All participants underwent a voice assessment protocol: ENT specialist examination and speech therapist evaluation. Acoustic parameters and subjective observations were obtained and analysed. R esults: Fundamental frequency (F0) level was distinctly decreased in the case of older female singers, but F0 in older male singers had stable levels in comparison to that in younger singers. Older singers were found not to have substantially different values of jitter than younger ones. Maximal phonation time (MPT) was longer in the older women’s group when compared to the younger singers, but not relatively different in the men’s group. Shimmer value presented no age-related change. Morphological changes seem to correlate with the age of subjects. C onclusions: The main characteristic of voice change with age was a decreased F0 level among older female professional singers and rather stable F0 levels in male singers. This study gives preliminary results on the ageing of voice in the population of professional opera singers.

In the second half of the 20th century, the history of European demography is associated with a pronounced and widespread process of ageing. The 21st century will have to cater to the needs of an elderly population in transformation. Portugal is also part of this process and in efforts to improve the quality of life of the elderly, a wide range of facilities, services and social responses have been established by a variety of promoters, targeting several social levels. This paper will analyze a specific segment directed at an exclusive niche of the elderly population, the Senior Residential Condominiums. This is a very recent segment of the housing market, with high levels of comfort, quality, sanitation, health, and recreation, essential to full well-being. The paper intends to characterize this real estate market niche so as to identify its distinctive features, the promoting agents and how they can contribute to residents' quality of life.

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.

Regulatory effect of CD25, an activation antigen the α subunit of interleukin 2 receptor (IL2R) on the activity of natural killer (NK) cells was studied in fifty elderly (57-70 years old) and fifty young people (19-35 years old). Cytotoxic NK activity was assessed by 51Cr release assay, the levels of interleukin 2 (IL2) and tumour necrosis factors α (TNFα) were measured using bioassays and expression of CD16 and CD25 proteins by flow cytometry. Low NK activity in the elderly was associated with decline of full health, lowered serum concentration of IL2 and increased production of TNFα during NK reaction. Inhibition of TNFα activity by anti-TNF monoclonal antibody suppressed exclusively NK activity of low NK responders. Moreover, stimulation in vitro of blood mononuclear cells, with TNFα induced in the elderly low NK responders a significantly higher increase of the CD25 expression on the surface of NK cells as compared with that in the elderly high responders. Since the CD25 molecule constitutes a subunit of the high affinity receptor, binding IL2 to immunocompetent cells, its increased expression on NK cells of low NK responders would enable them to bind even low amounts of the endogenous IL2 available in this group of the elderly. Thus, an overproduction of TNFα seems to be a mechanism compensating, in the non-fully healthy elderly, for the decreased IL2 production, promoting efficient cytotoxic reaction.

In this paper the influence of short and long term ageing processes on polymer dispersion in the polymer modified bitumen has been analyzed. The bitumen was modified by various amounts of SBS elastomers. Microstructural changes of polymer dispersion were tested using fluorescent microscopy. It has been shown that the phase separation of SBS modified binders is influenced by the base bitumen and the characteristics and content of the polymer. Correlations were sought between viscoelastic properties and microstructure after ageing. The results showed that it is essential to describe the microstructure of the polymer modified bitumen, especially the description phases, shapes and proportion of dispersed parts.

The aim of the study was to examine the health-related quality of life (HRQoL) of the elderly in Poland. Researcher investigated if differences between gender groups were influenced by other variables such as period of ageing („young-old” vr „old-old”) and place of residence (big city, small town, village). The study sample comprised 2565 elderly who were at least 60 years of age. The average age for men was 72,76 and for women 72,39. The health-related quality of life was evaluated using the Polish adaptation WHOQOL-BREF questionnaire. Respondents rated both quality of life and general health well. Nevertheless the health-related quality of life domains’ rating decreases with age. Women are commonly less satisfied with the WHOQOL-BREF domains. Men living in little towns declared not only a high level of quality of life, but their estimates in the early and late old age are similar. The diversity of health-related quality of life needs further investigation along with a number of more subjective indicators of individual experiencing one’s old age (e.g. sense of one’s time of life or the awareness of age-related changes).

Ciało we współczesnym społeczeństwie pełni rolę swoistej waluty, stając się cenionym dobrem. Promowane jest ciało młode – sprawne i zdrowe, stąd większość poszukiwań badawczych dotyczy młodych osób. Z uwagi jednak na starzenie się społeczeństw coraz więcej badaczy podejmuje problem doświadczania własnej cielesności w grupie osób w średnim i starszym wieku. Celem artykułu jest analiza badań poświęconych cielesności w grupie osób starszych i próba odpowiedzi na pytanie, na ile kult ciała dotyczy także tej grupy. Wyniki doniesień są często sprzeczne i trudno jednoznacznie wskazać, na ile zadowolenie z ciała zmienia się na przestrzeni życia, a także na ile zdrowie i sprawność fizyczna stają się ważniejsze niż atrakcyjny wygląd u osób starszych.

In modern society body plays significant role, thus becoming a great value. As young and healthy body is promoted, the majority of research explorations focuses on young people. However, due to ageing societies, more and more researchers investigate the problem of experiencing one’s body by middle-aged and elderly people. The main aim of this paper is to analyse the research on body in a group of elderly people. Also, the article attempts to answer the question as to what extent the cult of body can refer to this group. The results of research are often contradictory and it is difficult to clearly indicate how satisfaction with body changes across the life span and to what extent health and fitness become more important than looking attractive in elderly people.

A calibration procedure for quantitative determination of dibutylphthalate concentration in a double base propellant is established. The best results are obtained by dividing an absorption band, characteristic of the dibutylphthalate, by an absorption band characteristic of the double base mixture. The influence of the nitroglycerin concentration on the linear calibration curve is investigated and it is shown that a linear relationship can be obtained for different concentrations of nitroglycerin by multiplying the absorbance ratio by the nitrocellulose concentration. The developed analysis protocol is applied to characterize quantitatively the deterrent concentration profile of a flattened ball propellant. Since the measured profile in a given propellant grain is dependent of the orientation of the analysed cross-section, geometrical and concentration factors are used to eventually describe the profile perpendicularly to the grain surface. The validated experimental procedure is then applied to study the characteristic of the diffusion process of the deterrent throughout the grain by artificial ageing at different temperatures. From these results, diffusion coefficients and diffusion activation energy of 154 ± 15 kJ/mol have been obtained. Furthermore, a simulation program has been used to validate the used procedure for the calculation of the diffusion coefficient.

The paper focuses on the union formation in later life using SHARELIFE data from 13 European countries. First, it shows that proportion of single individuals aged 50-69 and the proportion of those who (re)partner vary significantly across European countries. The highest levels of (re)partnering were observed in Scandinavia and the lowest in Southern and Central Europe. Second, it shows that women are much less likely to enter a new coresidential union than men in all studied countries but the relative difference between men and women vary. The smallest difference was observed in Scandinavia and the Czech Republic, the largest in Southern Europe, Austria, and Switzerland. Third, repartnered individuals tend to be younger, more educated, and more likely divorced than widowed comparing to those who stay single.

Population ageing is one of the major challenges of modern Europe. In this context is worth to assessment the differences in the situation of women and men aged 50+ on the labour market. In the area of interest are primarily people aged 50-59/64, which are at this stage of life in which the situation on the labour market is particularly difficult. Paper was prepared mainly on the basis of the unpublished data developed within the project “Equalisation of Opportunities in the Labour Market for People Aged 50+”. The analysis was conducted with the application of basic descriptive statistics, as well as chi-squared test. Comparing income of women and men aged 50+, t-Student test and median test for independent samples, as well as one- and two-way analysis of variance were used.

The aim of this paper is to explore older in-migrants' experiences and perceptions of their spatial context at the neighbourhood level, the key aspects in their attachment to the neighbourhood, and the role of place in their experience of ageing. Our qualitative research was carried out in Newton Hall (United Kingdom). The findings show that older people can have a proactive role in terms of placemaking and their own wellbeing. However, the study also reveals that the condition of the spatial context can either support or hinder older people's sense of wellbeing.

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.

Senility is strongly associated with changes in body composition. Sarcopenic obesity (SO) consists of symptoms such as increased body fat mass and a reduction in muscle strength and/or mass. The review covered treatment methods and diagnostic criteria used in SO patients. Moreover, the impact of SO on the health of older people was reviewed. Papers from the Science Direct and PubMed databases were analysed. The following keywords were used: “sarcopenic obesity”, "diagnostic", "treatment", "elderly", and "physical therapy". The inclusion criteria encompassed research studies on SO in older people. To be precise, the review included papers from January 2015 to March 2020, and the review itself was carried out from March to April 2020. Out of over 1,200 SO articles, 18 met all inclusion and exclusion criteria. All of the chosen papers were divided into two main groups. The first group contained papers about SO’s impact on the health of older people. The second comprised works about SO treatment methods. The most commonly used SO diagnostic indicators were: BMI (25kg/m2-30kg/m2), BF% (27%-42%), SMI (x<24%-27%; SMI 0.789), and ALST (x<15.02 kg). SO was also assessed via the use of algorithms. Sarcopenic obesity is a common syndrome related to body composition in older people. Currently, SO patients can be effectively treated with aerobic and resistance training, whole-body electromyostimulations (WB-EMS), supplements, and psychological interventions. Due to the great impact of SO on people’s health, future studies should concentrate on systematising the diagnostic criteria for SO.

Purpose. Fatigue has been pointed as a fall risk in the elderly; however, the effects of prolonged gait on neuromuscular recruitment and on its pattern remain unknown. The aim of this study was to evaluate the effects of prolonged gait on neuromuscular recruitment levels and spatial-temporal gait variables. Methods. Eight healthy older women (age: 72.63 ± 6.55 years) walked at their preferred walking speed for twenty minutes on a treadmill. The Root Mean Square (RMS) from the vastus-lateralis, femoral biceps, tibialis anterior and lateral gastrocnemius muscles were determined at the first and last minute of the test during the moments of Heel Strike (HS), Terminal Stance and Terminal Swing (TS). In addition, coactivation in the knee and ankle as well as the stride cadence and length were measured in the test. The two RMS data (taken at the first and last minute) were compared by means of a Student's t-test. Results. Twenty minutes of walking induced fatigue in the subjects, as observed through an increase in RMS, notably during the HS and TS. Coactivation was also influenced by the prolonged gait test. The only gait phase where a risk of falling was enhanced was the HS. Nonetheless, subjects developed strategies to maintain a safe motor pattern, which was evidenced by an increase in stride length and a decrease in stride cadence. Conclusion. Tests lasting just twenty minutes on a treadmill were enough to induce fatigue in older adults. However, the level of fatigue was not enough to present a danger or fall risk to elderly individuals.
