The main goal of this research was to review the works that dealt with the effects of strength training in unstable conditions. A transparent survey covered 24 papers that were not older than 10 years. The sample of respondents are young and middle age groups due to similar abilities. Out of 24 papers: 16 papers were with one group in the experiment, 6 papers were with two groups in the experiment and 2 with three groups in the experiment. After the involvement of the musculature: 9 papers treated pectoral musculature, in 10 papers the involvement of the muscles of the lower limbs was processed, 6 papers dealt with the aspect of engaging the back musculature and the same abdomen, 8 papers treated chest musculature and two papers included shoulder musculature in their research. There was no difference in the degrees of promotion on the basis of gender in the articles. The statistical effect of exercise on unstable substrates was expressed in 13 studies, there were no statistically significant effects in 7 studies, while the same effect of the effects achieved by strength exercises on unstable and stable surfaces was found in 4 papers. The work done primarily suggests a positive effect of exercise on unstable substrates in untrained individuals.

Automated vehicles (AV) have the potential to benefit our society. Providing explanations is one approach to facilitating AV trust by decreasing uncertainty about automated decision-making. However, it is not clear whether explanations are equally beneficial for drivers across age groups in terms of trust and anxiety. To examine this, we conducted a mixed-design experiment with 40 participants divided into three age groups (i.e., younger, middle-age, and older). Participants were presented with: (1) no explanation, or (2) explanation given before or (3) after the AV took action, or (4) explanation along with a request for permission to take action. Results highlight both commonalities and differences between age groups. These results have important implications in designing AV explanations and promoting trust.

Surveillance of injury patterns and comparisons among different age groups help develop a better understanding of recent injury trends and early prevention. This study conducted a national surveillance of injury by age group. Data were collected retrospectively from Emergency Department-Based Injury In-Depth Surveillance (EDIIS) in South Korea, between January 2011 and December 2017. Patients were divided into the following four groups by age: Group 1–18 to 34 years, Group 2–35 to 49 years, Group 3–50 to 64 years, and Group 4—≥65 years. A total of 1,221,746 patients were included in the study. Findings revealed that, each year, the injury rate increased in the population aged ≥65 years. The place and mechanism of injury in Group 3 were similar to those in younger age groups, while injury outcomes and injured body parts were similar to those in Group 4. Further, hospital admission rate, ICU admission rate, hospital death, traumatic brain injury, and injury severity increased with an increase in age. In our study, each age group showed diverse characteristics pertaining to the mechanism, place, time, and outcomes of injuries. Interestingly, Group 3, which represented the late middle age, exhibited increased vulnerability to injury, and emerged as a gray zone between the young and old age groups. Therefore, different injury prevention methods are needed for each age group. Specifically, early prevention methods need to be implemented from the late middle age to improve the old age group’s injury outcomes.

ObjectivesExamine compliance with personal protective measures in communities for the prevention and control of local transmission of the COVID-19, and explore indicators for such behavioural compliance.DesignCross-sectional design with a self-selecting sample. Data collected in February 2020.SettingCommunity dwellers in China.Participants2956 participants aged 16 and above completed the study and were included in the analysis.Outcome measuresNationwide COVID-19 survey. Demographics and self-reported compliance with four personal protective measures—home quarantine, mask-wearing, temperature-taking and hand-sanitising were collected. Outbreak severity and timeliness of personal protection order were obtained from the China Center for Disease Control and Prevention website. Logistic regression models were employed to examine the association between demographic and social indicators and behavioural compliance.ResultsCompliance with home quarantine was only associated with gender (men, OR=0.61 (0.51–0.73), inverse association) but no other indicators. In contrast, men had higher compliance with mask-wearing (OR=1.79 (1.49–2.16)) and temperature-taking (OR=1.27 (1.05–1.53)). Compared with younger adults (≤20 years), the middle-age groups (31–40 and 41–50 years of age) were more compliant with all protective behaviours, except for home quarantine (OR=0.71 (0.54–0.93) and 0.67 (0.46–0.97), respectively).ConclusionMale gender was associated with lower compliance with home quarantine yet higher compliance with mask-wearing and temperature-taking. The middle-age participants (31–50 years) had lower compliance with home quarantine but higher with other measures. These findings may be supported by the economic considerations and the long-inherited Confucian values among Chinese. In light of the ongoing COVID-19 pandemic, public health authorities should tailor policy implementation to disparities in psychosocial indicators.

Abstract -The presence of information asymmetry increases transaction costs and reduces liquidity, and reduces the quality of investment decisions taken by investors. So that in turn it weakens the overall function of the market. Accounting disclosure plays a role in mobilizing information from management and investors so as to reduce information asymmetry. In addition, it is hoped that the presence of a concentration of investor ownership can carry out internal monitoring of the company so as to reduce information asymmetry. On the other hand, institutional investors have many incentives to access company information for their trading purposes due to the conflict of interest between outside investors and the board of directors. This study aims to determine the effect of disclosure quality and ownership structure on information asymmetry in companies listed on the Jakrta Islamic Index (JII) during the 2015-2019 period. Based on the results of panel data analysis of the Fixed Effect Model (FEM), it was found that institutional ownership had a significant positive effect on information asymmetry, while the quality of disclosure and ownership concentration did not have a statistical effect on information asymmetry.

Abstract Background Self-rated health (SRH) is widely used by health institutions due to its validity, reliability, predicted power for mortality and morbidity and simplicity of collection. However, limited research has been conducted to measure the health and explore the determinants of SRH among managers, especially in petroleum enterprises in China. The purpose of this study was to measure the overall health and identify the determinants of SRH among managers in petroleum production enterprises in China. We committed to provide evidence to improve managers’ health status by exploring the determinants of SRH.Methods From March 2017 to December 2018, 417 managers participated and were categorized into different gender and age groups. The effective rate was 84.2%. The scores for physical, mental and social health subscales were converted to binary categorical variables, and univariate and multivariate logistic regression analyses were used to identify the determinants of SRH.Results The mean scores for SRH measurement scale (MS) dimensions ranged from 65.69 ± 18.13 (mean ± SD) for positive emotion (M2) to 91.81 ± 15.18 for daily physical activities (B2). The findings showed that lower-income and medium-managerial-level managers in the 41- to 50-year-old age group and lower-income male participants were more likely to be of poor mental health, while lower-income managers in the middle age groups and middle-aged female managers tended to report poor social health.Conclusions This study is the first in the Chinese energy industry to report on SRH and its determinants among managers stratified by age and gender. We found that income and managerial level are the main determinants among the managers, especially for those of middle age. Psychological counseling and a harmonious and mutually supportive working environment can contribute to addressing the special needs of managers in Chinese petroleum-producing enterprises.

Green banking is different from traditional banking, as green banking focus on promoting environment friendly banking. Green banking is also known as ethical banking. This paper attempts to analyze the adoption of green banking products among customers with different age groups. ANOVA and post hoc tests are applied for analyzing the objectives. This paper finding explains that there is significant difference in the usage of green banking products across various age groups individuals, as young generation is more inclined towards green banking products than middle age and senior age groups. Therefore, more awareness is need to be created among the middle and senior age groups individuals.

<p><em>There are two different researches has been explain in this article. There is common idea of those two researches (Svence, Mihailova, Bebre, 2014)- does age as correlate statistical significant differ scores of mindfulness, wisdom and coherence.</em></p><p><em>The aim of the first research (Svence, Mihailova, 2014) is to make theoretical and practical analysis of correllations between sense of coherence, mindfulness and wellbeing among 25-45 year old women, as also make qualitative analysis in order to explore one of the sense of coherence categories – meaningfulness. Reserach has shown that there exists positive correlation between wellbeing and sense of coherence and between wellbeing and mindfulness, as aslo it has been shown that higher scores of sense of meaning in life is related to higher scores of wellbeing, yet there are nearly no research where the correlations between mindfulness and sense of coherece and/or meaningfulness would be explored. Yet there are enough research where the realaton of these concepts with other concepts such as self-efficacy, anxiety, stressreactivity is confirmed. Considering the above mentioned it is valuable to explore relations between sense of coherence, mindfulness and wellbeing. </em></p><p><em>Principal question of the research was to investigate if there is an association between sense of coherence, mindfulness and wellbeing, as also to make qualitative and quantitative analysis and acquire the broader understanding of this association. There were 36 participants in the research who were asked to fill three questionnaires via internet and to particiapate in the interview. Quantative methods were used in the research (Fife Facet Mindfulness Questionnaire, Orientation to Life Questionnaire to measure sense of coherence, Scales of Psychological Well-Being), as well as statistical methods (Pearson correlation) and qualitative method (content analysis of narratives). </em></p><p><em>Quantitative analysis confirmed the question of the research, since there were significant positive correlations discovered between all three concepts – sense of coherence, mindfulness and wellbeing. Content analysis of narratives was made and several typical content units were discovered whish are related to age appropriate meaningful life tasks, and to the processes of sense of coherence. Therefore the associatio between meaningfulness and other sense of coherence components was confirmed. </em></p><p><em>There is other research (Svence, Bebre,2014) about wisdom and meaningfulness scores- how they  correlates and differes in different age subgroups in adulthood.</em></p><p><em>There are some results show- scores of wisdom and meaningfulness are not significant differ in different age groups- early adulthood (20-35), middle age (40-55)  mathematical statistical significant, but differences has been finded about wisdom in early adulthood and middle age – according scores – wisdom is more higher in middle age as in early adulthood.</em></p><p> </p>

For the benefit of a younger audience, the cherry can be further enhanced by freeing it from the fruit group and allowing it to become part of the world of desserts and special treats. On the contrary, the localisms, traditions, and seasonality which characterize much of the national production can be further emphasized for the middle age and the “differently young” age groups, especially for the domestic market. Common to these diverse strategies is the need for high performance varieties linked to a structured sales season and non-destructive sorting with the use of the latest technologies to guarantee what the English-speaking world calls “consistent quality” and what we could rename “quality that lives up to our promises.”

The effects of gait speed and step length on the required coefficient of friction (COF) confound the investigation of age-related differences in required COF. The goals of this study were to investigate whether age differences in required COF during self-selected gait persist when experimentally-controlling speed and step length, and to determine the independent effects of speed and step length on required COF. Ten young and 10 older healthy adults performed gait trials under five gait conditions: self-selected, slow and fast speeds without controlling step length, and slow and fast speeds while controlling step length. During self-selected gait, older adults walked with shorter step lengths and exhibited a lower required COF. Older adults also exhibited a lower required COF when walking at a controlled speed without controlling step length. When both age groups walked with the same speed and step length, no age difference in required COF was found. Thus, speed and step length can have a large influence on studies investigating age-related differences in required COF. It was also found that speed and step length have independent and opposite effects on required COF, with step length having a strong positive effect on required COF, and speed having a weaker negative effect.
