Participation in community gathering place and social capital
Community gathering places participation was positively associated with nine social capital indicators; frequency of meeting friends (B: 0.55), number of friends seen within a month (B: 0.49), number of community organizations (B: 0.28-0.55), norms of reciprocity (B: 0.18), and attachment (B: 0.15); all results showed p1
Social disconnection and suicide mortality among Japanese older adults
Avoidance of not only depressive symptoms, but also social disconnection including eating alone, is useful in suicide prevention among older adults
Does social participation foster social support among the older population in Japan? A three-year follow-up study from the Japan gerontological evaluation study
Whether social participation has generated new, healthier social support is unclear.•We prospectively examined whether social participation fosters social support.•Social support was dose-responsive to the number of types of social participation.•Social support was fostered by participating in some type of group at any frequency.•Support to encourage social participation may be effective to enhance social support
Home-Based Frailty Prevention Program for Older Women Participants of Kayoi-No-Ba during the Covid-19 Pandemic
This study presents a single-arm intervention that aimed to determine the feasibility of a three-month home-based exercise program to prevent the progression of frailty during COVID-19. We recruited four groups of Kayoi-no-ba, or community salons for frailty prevention, and a total of 69 community-dwelling older women who belonged to one of the Kayoi-no-ba in a preliminary study for a follow-up study. The intervention program was developed on the…
Association between Increasing Social Capital and Decreasing Prevalence of Smoking at the Municipality Level
As smoking cessation is crucial for both individual and public health, this study aimed to elucidate the association between changes in social capital and in terms of smoking at the level of municipal units in Japan. Using repeated cross-sectional data from the Japan Gerontological Evaluation Study, we analyzed data from adults aged 65 years or older from 69 municipal units that participated in two survey waves. We received valid responses from 9…
Suggesting Indicators of Age-Friendly City
Ascertaining progress in building age-friendly cities (AFCs) requires community diagnostic indicators. This study examines the relationship between social participation and happiness at the municipal level. The data from the Japan Gerontological Evaluation Study (JAGES) from 2013, 2016, and 2019, comprising 442,079 older people from 289 municipalities, are used. We also employ linear mixed-effects models to evaluate the association between social…
Association between community-level social capital and frailty onset among older adults
BACKGROUND: Little is known about the prospective association between community-level social capital and individual-level frailty onset. Therefore, this study aimed to examine the impact of community-level social capital on frailty onset among older adults using 3-year longitudinal data. METHODS: This prospective cohort study recruited non-institutionalised older adults from the Japan Gerontological Evaluation Study, established in 2013 and robus…
Non-destructive in-situ classification of sandstones used in the Angkor monuments of Cambodia using a portable X-ray fluorescence analyzer and magnetic susceptibility meter
The Angkor monuments were built between the 9th and 15th centuries using gray to yellowish brown sandstone, red sandstone, and greywacke, which are petrologically classified as feldspathic arenite, quartz arenite, and feldspathic to lithic wacke, respectively. Gray to yellowish brown sandstone was generally used in all of the Angkor monument temples. Red sandstone was used as the main building material in the Banteay Srei temple but was also occa…
The Sandstone Quarries of the Angkor Monuments in the Southeastern Foothills of Kulen Mountain
The Angkor monuments in Cambodia were designated as a UNESCO World Heritage Cultural Site and consist of Buddhist or Hindu temples built mainly of sandstone and laterite. We surveyed the area around a 2 km east-west bank in Kulen Mountain’s southeastern foothills for Angkor’s sandstone quarries and confirmed 145 locations. Because the magnetic susceptibilities and size of sandstone blocks at Angkor changed systematically over time, we measured th…
Intensity of community-based programs by long-term care insurers and the likelihood of frailty
The World Health Organization (WHO) argues that governments can postpone declining capacity of older adults by providing sufficient support. Yet, to our knowledge, no study has focused on the role of local governments for realizing healthy ageing. This study examined the association between the intensity of community-based programs for frailty postponement by long-term care insurers (as municipalities) and the likelihood of frailty. We analyzed r…
Change in Municipality-Level Health-Related Social Capital and Depressive Symptoms
Prevalence of depressive symptoms is lower in communities with greater social capital (SC). However, it is unclear whether a prevalence of depressive symptoms will decrease in communities where SC has increased. We investigated the relationship between the changes in municipality-level SC and depressive symptoms by using 5-year repeated cross-sectional data from the Japan Gerontological Evaluation Study. In 2010 and 2016, self-reported questionna…
Regional Differences in the Chemical Composition of Cuneiform Clay Tablets
To elucidate regional differences in the chemical composition of cuneiform clay tablets originating from Iraq and Turkey, chemical analysis was conducted using portable X-ray fluorescence analyzers. The analysis included clay tablets from the 21 areas of Ur, Larsa, Lagash, Uruk, Umma, Adab, Drehem, Nippur, Kish, Borsippa, Dilbat, Babylon, Sippar, Nusi, Nimrud, Nineveh, Tell Brak, Tell Halaf, Boghazkoy, Kultepe, and Alalakh, currently stored in th…
Blackening of the Surfaces of Mesopotamian Clay Tablets Due to Manganese Precipitation
Blackening was observed on the surfaces of Mesopotamian clay tablets from Umma, Dilbat, Larsa, Ur, Babylon, Uruk, Sippar, and Nippur produced between the Third Dynasty of Ur and the Early Achaemenid Dynasty. Portable X-ray fluorescence analysis revealed that manganese was concentrated on the blackened surfaces. Rod-shaped materials with a length of 100 - 200 nm and a width of 30 nm were observed using a field emission scanning electron microscope…
