The method developed to analyze the components of cigarette odors is capable of quantitatively evaluating lingering odor using a simple procedure. The odor intensity is then estimated by condensing the gas evaporated from curtain material previously exposed to cigarette odors and subsequently analyzing the gas with gas chromatograph mass spectrometry. The lingering odor has been confirmed to contain aldehyde, olefin, heterocyclic and heteroaromatic compounds. After confirming the linear correlation between the logarithm of vinyl pyridine concentration and the six-level odor intensity, a simplified method of estimating the intensity of lingering odors has become possible by using the vinyl pyridine concentration.
This study focused on the odors in elder care environments, as odors are one of the most important issues in long-term care environments. The aim of this report is to clarify the actual condition of home care and how caregivers evaluate the care environment.To achieve this, we conducted a questionnaire survey of caregivers living together with the elderly who use long-term care insurance.The results were as follows 1. More than 70% of the elderly are over 80 years old, and 28% are certified as care level 4 or 5, which means that they require substantial care or support in daily life. A total of 52% of the caregivers take care of the elderly without any support from other family members.2. Irrespective of the care level, home care of the elderly is a burden to the caregiver. Over 60% of the caregivers think that it is difficult to contact their friends, maintain their social life and invite people home.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
