People hope to live a healthy and happy life achieving satisfaction by striking a good work-life balance. Therefore, there is a growing interest in well-aging which means living happily to a healthy old age without worry. This study identified important factors related to well-aging by analyzing news articles published in Korea. Using Python-based web crawling, 1,199 articles were collected on the news service of portal site Daum till November 2020, and 374 articles were selected which matched the subject of the study. The frequency analysis results of text mining showed keywords such as 'elderly', 'health', 'skin', 'well-aging', 'product', 'person', 'aging', 'female', 'domestic' and 'retirement' as important keywords. Besides, a social network analysis with 45 important keywords revealed strong connections in the order of 'skin-wrinkle', 'skin-aging' and 'old-health'. The result of the CONCOR analysis showed that 45 main keywords were composed of eight clusters of 'life and happiness', 'disease and death', 'nutrition and exercise', 'healing', 'health', and 'elderly services'.

Purpose : The purpose of this study was to investigate the effect of the sprinter and skater combined patterns on muscle contraction onset time and muscle activation of body stabilizing muscles. Method : Our study included young and healthy men in their 20s. The participants used the sprinter and skater combined patterns of the proprioceptive neuromuscular facilitation (PNF) methods to measure muscle activation and muscle contraction onset time of the trunk muscles. To measure muscle contraction onset time and muscle activation, electrodes were attached to the rectus abdominis (RA), external oblique (EO), internal oblique (IO), and erector spinalis (ES) regions. Significant differences were identified using a paired t-test and a one-way analysis of variance (ANOVA) analysis. Result : In the sprinter combined pattern, the muscle with the fastest onset time of contraction was the RES, and that with the slowest was the RRA (p<.001). In the skater combined pattern, the muscle with the fastest onset time of contraction was the LES, and that with the slowest was the LRA (p<.001). In the sprinter combined pattern, the REO and LIO presented medium muscle contraction onset times (p<.001). In the skater combined pattern, the LEO and RIO presented medium muscle contraction onset times (p<.001). Conclusions: Based on these results, these patterns could be used as exercise methods for the elderly with delayed proactive response speeds of the body stabilization methods due to imbalances in body stabilizing muscles or limbs movement.

Purpose: The purpose of this study was to determine the asymmetrical difference between the use of leg muscles on the surgical and non-surgical sides during initial lower extremity ergometer exercise after unilateral knee arthroplasty. Methods: Twelve elderly patients diagnosed with degenerative arthritis of the knee and who underwent unilateral arthroplasty were included in this study. The leg length of each subject was taken into account when setting the application distance of the lower extremity ergometer. The same pedal resistance, strength, and speed were used for all the subjects. The total angle of use of the ergometer (360°) was analyzed by dividing it into an extension section and a flexion section. Using a surface electromyography system, the activities of the muscles of the surgical and non-surgical sides were converted into maximal voluntary isometric contraction (MVIC) and analyzed using the paired t-test. Results: When the activities of the muscles on the surgical and non-surgical sides were compared, it was found that the rectus femoris and biceps femoris had significant differences in the flexion and extension sections (p < .05), and that the tibialis anterior significantly differed in the flexion section (p < .05). There was no significant difference in the extension section of the tibialis anterior muscle, or in the flexion and extension sections of the gastrocnemius (p >.05). Conclusion: The results of this study confirm that the rectus femoris, tibialis anterior, biceps femoris, and gastrocnemius on the surgical side act in an opposite manner to those on the non-surgical side during pedaling in the same section.

PURPOSE: Many studies have reported the improvement of cognition through physical activity among subject with dementia. This study aimed to whether the current studies supports that physical activity intervention is efficacious on cognitive performance in subject with dementia. METHODS: Two independent reviewers searched National assembly library, RISS, KISS (2005-2015) using the concepts of dementia, exercise, and physical activity. We included randomized controlled trials that examined the efficacy of physical activity in subject with dementia. A meta-analysis was performed to estimate the effect sizes cognition with CMA (Comprehensive Meta-Analysis, version 2.2.064) soft-ware program. Nine randomized controlled trials were included, providing data from 133 individuals and excluding those failing to criteria of this study. RESULTS: The meta-analysis showed that physical activity intervention had a rather small effect sizes of 0.36 (95% confidence interval 0.14-0.59) on cognition performance in subject with dementia. Outcome measurement were MMSE-K (Mini-mental state examination Korean version) and LOCTA (Loewenstein Occupational Therapy Cognitive Assessment). We found heterogeneous among studies and there was difference between the studies (Q = 19.63, d(f)=12, $I^2= 38.88$). CONCLUSION: The present analysis suggests that physical activity interventions have the low effect sizes on cognition performance in subject with dementia Further studies will be required to develop the various programs for improving the cognitive performance in subject with dementia.

The objective of this study is to develop a sizing system of fitness clothing that can properly accommodate various body sizes of Korean senior women. The sizing system of upper and lower fitness clothing was developed in the present study by selection of key variables, identification of size category candidates, and determination of an optimal sizing system. First, key anthropometric dimensions (stature and bust circumference for upper clothing and stature; waist circumference for lower clothing) were identified by factor analysis on the direct body measurements (n = 272) and 3D whole-body scan data (n = 271) of Korean senior women in Size Korea. Second, sizing system candidates based on the key dimensions of upper and lower clothing were explored using a grid method and an optimization method. Lastly, among the sizing system candidates, optimal sizing systems of upper and lower clothing were selected in terms of accommodation rate. Five size categories (short/small, short/medium, tall/small, tall/medium, and tall/large) were selected as the optimal sizing systems of upper and lower clothing with 89% and 78% of accommodation rate, respectively, for the Korean senior women. The anthropometric characteristics of the representative humans of the optimal size categories would be of use in the design of fitness compressive wear for the better fit and effectiveness of exercise and health of Korean senior women.
