This study aimed to investigate the correlation between instrumental activities of daily living (IADL), depression, electronic device utilization (EDU) and life satisfaction in older adults and to evaluate the dual mediating effect of EDU and life satisfaction on the relationship between IADL and depression. A secondary data analysis of the 2020 Korean Elderly Survey was carried out with 9906 older adults. The dual mediating effect was analyzed using model 6 of PROCESS Macro for SPSS v. 4.1 (New York, NY, USA). EDU (B = −0.010, 95% CI [0.007, 0.013]) and life satisfaction (B = 0.071, 95% CI [0.064, 0.079]) each had a mediating effect on the relationship between IADL and depression in older adults, and in particular, these two variables were shown to dual mediate (B = 0.017, 95% CI [0.015, 0.019]). This study confirmed that life satisfaction can be increased and depression decreased by improving the ability to use electronic devices to combat the limitations in daily functioning due to aging. It is necessary to establish a strategy to increase EDU as a part of the intervention methods for managing depression in older adults.

There is a need to comprehend dental accidents accurately, and construct patient-safety-system in order to prevent consistently increasing dental accident or dispute. This study is aimed to provide basic data for an efficient counterplain by looking through and classifying already occurred dental accidents from an angle of patient safety. Recently, the number of dispute on dental implant was the highest according to rapid growth of dental implant. As a result of classifying dental accidents by International Classification for Patient Safety (ICPS), it is confirmed that cause of accident is different by each type of dental treatment. It is expected to help preventing and managing dental disputes properly by studying actual state of dental disputes in perspective of patient safety. Effort to reduce dental accidents and activity to pursue patient safety have thread in connection. I believe that financial profits of dental clinic and improvement of quality in dental treatment can be achieved through these efforts.
