We aimed to provide evidences for developing non-pharmacological intervention in older adults with Mild Cognitive Impairment(MCI) by integrated literature review. The final 16 papers were selected as a result of an integrated literature analysis. All of them are focused on strengthening cognitive activities, while Korean studies have often merged emotional activities such as music therapy and laughter therapy rather than physical activities such as exercise therapy, international studies have combined physical activities rather than emotional activities. The effects of non-pharmacological intervention differed according to the outcome variables. The primary variables were cognitive function and depression, and secondary variables were found to have effects on physical function, activities of daily living (ADL), and self-efficacy. This study contributes to a multidisciplinary approach that can be applied in the clinical field through the development of various non-pharmaceutical intervention for the prevention of dementia in the older adults with MCI.

The purpose of this study was to identify health literacy among elderly and to investigate the relationships between healthy literacy and health status. A cross-sectional study was conducted with a sample of 158 participants between July and December 2019. The linguistic and functional health literacy (using the KHLAT and NVS) and self-rated physical and mental health were assessed. Above third of elderly have difficulties reading and understanding linguistic and functional health literacy. There were significant differences in health literacy according to residence, spouse, living together, educational level, occupation, monthly income, and number of diagnosed disease. Linguistic and functional health literacy and self-rated physical and mental health are closely related. Sociodemographic and disease related factors such as residence, educational level, monthly income, and multi-morbidity need to be considered when developing educational programs to improve health literacy. It could be possible to promote health status by improving the health literacy through individualized convergent educational program.

This study was conducted to determine which factors would predict metabolic syndrome (MetS) perception and exercise by applying a machine learning classifier, or Extreme Gradient Boosting algorithm (XGBoost) from July 2014 to December 2015. Data were obtained from the Korean Community Health Survey (KCHS), representing different community-dwelling Korean adults 19 years and older, from 2009 to 2013. The dataset includes 370,430 adults. Outcomes were categorized as follows based on the perception of MetS and physical activity (PA): Stage 1 (no perception, no PA), Stage 2 (perception, no PA), and Stage 3 (perception, PA). Features common to all questionnaires for the last 5 years were selected for modeling. Overall, there were 161 features, categorical except for age and the visual analogue scale (EQ-VAS). We used the Extreme Boosting algorithm in R programming for a model to predict factors and achieved prediction accuracy in 0.735 submissions. The top 10 predictive factors in Stage 3 were: age, education level, attempt to control weight, EQ mobility, nutrition label checks, private health insurance, EQ-5D usual activities, anti-smoking advertising, EQ-VAS, education in health centers for diabetes, and dental care. In conclusion, the results showed that XGBoost can be used to identify factors influencing disease prevention and management using healthcare bigdata.

Mitochondrial biogenesis-a process that leads to an increment in the number and density of mitochondria, improves physical performance and body health by enhancing exercise capacity. In the present study, we investigated the stimulatory effect of Ashitaba and red ginseng complex (ARC) on exercise capacity in L6 skeletal muscle cells and mice. In L6 skeletal muscle cells, ARC increased the mitochondrial contents and ATP production by activating AMP-activated protein kinase (AMPK), sirtuin 1 (SIRT1), and peroxisome proliferator-activated receptor gamma coactivator-1 alpha (PGC-$1{\alpha}$) and up-regulating the mRNA expression of nuclear respiratory factor-1 (NRF-1) and mitochondrial transcription factor A (TFAM). In the animal experiments, mice treated with ARC showed an increment in exercise capacity as compared with mice treated with Ashitaba extract or red ginseng extract alone. These studies indicate that ARC might serve as a potential natural candidate for enhancing exercise capacity by stimulation of mitochondrial biogenesis.

Age related decrease of muscle strength, balance, and gait abilities bring about physical inactivity in the elderly. Virtual reality (VR) training has been used successfully to rehabilitate functional balance and mobility in elderly subjects. This study was aimed at determining the effect of VR-based exercise programs by using a video game on the muscle strength, balance, and gait abilities in the elderly. 48 old people were randomly divided into two groups; VR-group (men: 11, women: 14, age: 68.42yrs) and control group (men: 10, women: 13, age: 67.58yrs). VR-group performed an exercise program twice a week for 8 weeks and control group had no intervention. The VR-based exercise program was composed of warm up(10 mins), VR-program(40 mins), and cool down(10mins). It was performed by playstation eyetoy play that provided visual and auditory feedback as well as movements of the upper and lower extremities. Muscle strengths of the knee and ankle were measured using manual muscle tester. Static balance was estimated using computerized posturography. Dynamic balance was measured by Timed up and go test (TUG), Functional reach test (FRT). 10m walk test and 6-min walk test were used to assess gait abilities. After the completion of the VR-exercise program, muscle strength, balance, and gait abilities were improved significantly (p<0.05). In conclusion, the VR-based exercise program showed improvement on the muscle strength, balance, and gait ability in the elderly. This exercise program is both effective and interesting for this age group.

Currently, Korea is changing into an ultra-aging society, and office workers retire at the age of 49.5 on average from their main jobs, and the national pension is delayed from 62 years old to 65 years old by 2034, so research is needed to prepare for the aging of office workers after retirement. The purpose of this study is to examine the factors affecting the intention to start a business after retirement and the mediating effect of another sense of success expectation on life after retirement, targeting office workers nationwide. Changes in individual attitudes and systematic institutional support are needed to prepare for a sustainable job until the age of 100 after retirement, that is, a start-up utilizing wisdom and experience in work life. As a result of the study, the ability to perform the goal as job performance, economic preparation for retirement preparation, preparation for external relations, and future anxiety have a positive effect on the entrepreneurial will, and the ability to use new technologies as job performance, and physical preparation for retirement. Preparation and preparation for internal relations were found to have no effect. In the influencing relationship between preparation for external relations and the will of start-up, and future anxiety and will of start-up, another sense of success was confirmed to have a partial mediation effect. In the relationship between economic preparation and willingness to start a business, the effect of complete mediation was confirmed. In order to increase the will to start a business after retirement, it was confirmed that another sense of expectation for success was an important variable. Introducing a government-sponsored education system in the company to reduce the government's financial burden due to super-aging and achieve corporate growth through employee training while potential founders, office workers, are employed, and entrepreneurship and goals for the three life goals of office workers By introducing a performance improvement program, we were able to get implications that would be a solution to the growth of individuals and businesses and reducing the government's financial burden.

This study was understood the risk mechanism of falls in the elderly and reviewed previous research data to see if the principle of Pilates rehabilitation exercise could have a positive effect on balance ability and postural stabilization in the elderly, and the purpose of this study is to present literature-based data on the fall prevention effect of rehabilitation Pilates exercise. First, the rehabilitation Pilates exercise makes it available for strengthening the center of the body to stabilize the spine and pelvis and stimulates the nerve root, thereby having an effect on the balance and the joint stabilization. Second, a proprioceptive sensory impairment and a musculoskeletal degenerative disease due to aging increase the loss of balance ability and the instability in posture maintenance, thereby coming to raise the risk of a fall damage caused by the difficulty in performing motor functions and by the gait disturbance. Third, the rehabilitation Pilates exercise leads to improving the core muscle strength in older adults, resulting in being capable of expecting the betterment in the balance and the reaction time motor function. And there is a positive impact on the improvement in body imbalance and on the stability in movement involved in the fall prevention, resulting in being able to suggest the possibility of likely contributing to a reduction in a fall risk rate. In conclusion, the rehabilitation Pilates as the elderly exercise program showed effects on the improvement in the body's muscular strength, on the upgrade in a sense of balance, and on the stabilization of core. Thus, it was considered to diminish the risk factors for a fall damage caused by musculoskeletal degeneration and to be capable of preventing a serious disorder of activity due to a chronic senile disease.

Purpose: The purposes of this study was to identify the health status, health-related life habits, activities of daily living and biophysical index of the elderly in Korea and Japan respectively, and to compare the Korean elderly with those of the Japanese elderly. Method: Two hundred ninety five elderly from Korea and 325 elderly from Japan, aged over 65 years were conveniently recruited from welfare centers in both countries. Health status, health-related life habits, and activities of daily living were assessed by self-report questionnaires. BMI, lean body mass, body fat, body fat rate, muscle area of limbs and grip strength were measured for biophysical indices. Descriptive statistics, non paired t-test and Chi-square test were used to describe and to compare the levels of these variables. Results: The mean scores on frequencies of Korean and Japanese elders' chronic diseases were 2.9 and 0.8. The mean scores on activities of daily living were 9.8 and 12.4 respectively. The Korean elderly had higher mean scores of BMI, and body fat rate than The Japanese elderly, and showed lower mean scores of muscle areas of the lower extremities and grip strength. Hypertension was the most prevalent disease in the both groups. Conclusion: Significant differences in several variables of health status, health-related life habits, activities of daily living and biophysical index were noted between the Korean and Japanese elderly.
