Assessing caregiver burden: the role of assistive devices and identification of assistive device needs.

Purpose: There is insufficient information on whether the use of assistive devices is associated with a lower burden on caregivers of individuals with disabilities. This study was conducted (1) to examine how care recipient-level factors, caregiver-level factors, and the use of assistive devices were associated with caregiver burden, and (2) to investigate the assistive device needs of caregivers.

Materials And Methods: This cross-sectional descriptive study used surveys.

Longitudinal trends and predictors of limitations in activities of daily living in community-dwelling older adults: evidence from the KLoSA study.

Background: As life expectancy increases, the number of older adults with functional limitations is also increasing. Functional limitations are associated with adverse health outcomes such as reduced independence, diminished quality of life (QoL), and disability. Therefore, identifying which activities of daily living (ADLs) are limiting and understanding the influencing factors are crucial for developing tailored interventions.

Validation of the Korean version of the Summated Xerostomia Inventory among older adults residing in nursing homes.

Background: Xerostomia is commonly experienced by older individuals. We sought to develop and evaluate the reliability and validity of the Korean version of the Summated Xerostomia Inventory (K-SXI) among older adults residing in long-term care facilities (LTCFs) in Korea.

Methods: In this secondary data analysis study using cross-sectional data, a cross-cultural adaptation process was conducted for the Korean version before data collection.

Changes in instrumental activities daily living limitations and their associated factors according to gender in community-residing older adults: A longitudinal cohort study.

Background: Increases in dependence among older adults cause increases in care needs and social care burden. Instrumental activities of daily living (IADL) are often used to assess the independence of older adults residing in communities. Various factors affect IADL limitations, but few studies confirm gender differences in IADL limitations in older adults.

Factors Associated With Functional Limitations in Daily Living Among Older Adults in Korea: A Cross-Sectional Study.

This paper assesses the relationship between demographics, health parameters, and functional limitations among older adults in Korea, including limitations in activities of daily living (ADLs) and instrumental activities of daily living (IADLs). We analyzed data from the Korean Longitudinal Study of Aging survey in 2020 and included only participants aged 65 and older. Multinomial logistic regression models were conducted to evaluate the factors that predicted functional limitations.

Comparison of Beef Palatability Characteristics between and Muscles from Different Grades during Postmortem Aging.

The objectives of this study was to compare palatability changes of the (LT) and (VL) muscles of Hanwoo steers from different beef quality grades (1 and 1) during 28 d of wet-aging in order to improve the utilization of the VL muscle as a steak. The VL muscle showed a higher collagen content and a lower intramuscular fat content than the LT muscle (p<0.05).

Associations of Heat-Shock Protein Expression with Meat Quality and Sensory Quality Characteristics in Highly Marbled Muscle from Hanwoo Steers Categorized by Warner-Bratzler Shear Force Value.

The influence of heat-shock protein (HSP) concentrations at 45 min and 24 h postmortem on meat quality and sensory quality characteristics of muscle from highly marbled Hanwoo steers (beef marbling standard grade 6-8) was investigated. Muscle samples were segregated into three groups based on Warner-Bratzler shear force (WBSF) value. The low group exhibited a lower WBSF value compared to the medium and high groups (37.

Comparison of Marbling Fleck Characteristics and Objective Tenderness Parameters with Different Marbling Coarseness within Muscle of High-marbled Hanwoo Steer.

It is important to understand how marbling traits and tenderness differ among beef steaks from the carcass grading site and other regions within the (LT) muscle, as these characteristics are closely associated with consumer acceptability and willingness to purchase. Thus, the aim of this study was to compare the marbling fleck traits and objective tenderness parameters in the groups classified by the coarseness index (CI) of marbling fleck (high and low groups) at the carcass grading site (13 thoracic vertebra; 13T) and three different locations (13T, 9T, and 6T) within the LT muscle from well-marbled (marbling score 7 to 9) Hanwoo steer. Image analysis showed that the longitudinal locations had a significant effect on marbling fleck traits.

Application of the remote microphone method to active noise control in a mobile phone.

Mobile phones are used in a variety of situations where environmental noise may interfere with the ability of the near-end user to communicate with the far-end user. To overcome this problem, it might be possible to use active noise control technology to reduce the noise experienced by the near-end user. This paper initially demonstrates that when an active noise control system is used in a practical mobile phone configuration to minimise the noise measured by an error microphone mounted on the mobile phone, the attenuation achieved at the user's ear depends strongly on the position of the source generating the acoustic interference.

Fear of falling and its predictors among community-living older adults in Korea.

Objectives: To explore the prevalence and predicting factors of fear of falling (FOF) among community-living older adults in Korea.

Methods: Secondary data analysis of the 2011 Korean National Elderly Living Conditions and Welfare Desire Survey was used. Logistic regression analysis was conducted to examine the predictors of FOF.

Comparative analysis of cognitive tasks for modeling mental workload with electroencephalogram.

Previous electroencephalogram (EEG) studies have shown that cognitive workload can be estimated by using several types of cognitive tasks. In this study, we attempted to characterize cognitive tasks that have been used to manipulate workload for generating classification models. We carried out a comparative analysis between two representative types of working memory tasks: the n-back task and the mental arithmetic task.

A review on the computational methods for emotional state estimation from the human EEG.

A growing number of affective computing researches recently developed a computer system that can recognize an emotional state of the human user to establish affective human-computer interactions. Various measures have been used to estimate emotional states, including self-report, startle response, behavioral response, autonomic measurement, and neurophysiologic measurement. Among them, inferring emotional states from electroencephalography (EEG) has received considerable attention as EEG could directly reflect emotional states with relatively low costs and simplicity.

Classification and identification of recorded and synthesized impact sounds by practiced listeners, musicians, and nonmusicians.

Three experiments were conducted to test the viability of a low-parameter modal model for synthesizing impact sounds to be used in commercial and psychoacoustic research. The model was constrained to have four physically based parameters dictating the amplitude, frequency, and decay of modes. The values of these parameters were selected by ear to roughly match the recordings of ten different resonant objects suspended by hand and struck with different mallets.

Children's detection of pure-tone signals: informational masking with contralateral maskers.

When normal-hearing adults and children are required to detect a 1000-Hz tone in a random-frequency multitone masker, masking is often observed in excess of that predicted by traditional auditory filter models. The excess masking is called informational masking. Though individual differences in the effect are large, the amount of informational masking is typically much greater in young children than in adults [Oh et al.

One factor underlies individual differences in auditory informational masking within and across age groups.

Masked threshold for a pure-tone signal can be substantially elevated whenever the listener is uncertain about the spectral or temporal properties of the masker, an effect referred to as auditory informational masking. Individual differences in the effect are large, with young children being most susceptible. When masker uncertainty is introduced by randomizing the frequencies of a multitone masker on each presentation, the function relating a child's pure-tone signal threshold to the number of masker components is found to be substantially elevated above that of most adults.
