Abstract

ABSTRACT Introduction: The increase in life expectancy makes the cognitive abilities of the elderly important. The need for a rapid diagnosis of cognitive impairment renders the currently available instruments inadequate. Standardization of the use of voice analysis for cognitive assessment is required for quick diagnosis. Aim: To determine the relationship between voice components and cognitive impairment in the elderly. Methods: A descriptive and analytical cross-sectional study was conducted on elderly individuals over 60 years old who did not have visual or hearing impairments. Cognitive assessment using MoCA-INA was performed on 107 elderly individuals who met the inclusion criteria and were categorized into normal and cognitively impaired groups. Results: The majority of the study respondents were aged 61-70 years (57.9%), not frail (93.5%), had multimorbidity (60.74%), had a habit of exercising (66.4%), and had a formant frequency 1 (F1) of the vowel /e/ <500.9 Hz (50.5%). Univariate analysis showed that F1 of the vowel /e/ had very high variability (107041.294), and the compare means analysis showed a significant relationship (p=0.034). Discussion: Most of the elderly in this study did not have cognitive impairment. There was a relationship between F1 of the vowel /e/ and cognitive impairment at a MoCA-INA cut-off score of 22. There was no relationship between age, exercise habits, multimorbidity, fundamental frequency of the vowels /a/ and /e/, amplitude of the vowels /a/ and /e/, F1 and F2 of the vowel /a/, and F2 of the vowel /e/. Keywords: cognitive impairment, elderly, formant 1 (F1), voice analysis

Abstract

Photography studios often require various lighting arrangements for different photo and video shooting themes. Lighting in a studio environment is critical to producing high-quality images and videos. However, conventional lighting sources, such as lamps or other lighting equipment, are often inflexible to reposition according to the photographer’s desired thematic setup. Manual lighting adjustments can be time-consuming, mainly when automated positioning features are unavailable. This inefficiency hampers the photo and video shooting process. In the community service program discussed in this article, the team from the Mechanical Engineering Department at Atma Jaya Catholic University of Indonesia developed a motorized stepper-based lighting system with railing to address the inefficiencies in studio lighting adjustments. The team partnered with Kolaborasi Berkat Kreasindo (KBK) studio. The developed lighting system can be controlled remotely, eliminating the need for direct manual adjustments. This solution has assisted the partner studio in enhancing the lighting setups for photography sessions.
