As we enter a super-aged society, studies are being conducted to reduce complications and deaths caused by falls in elderly adults. Research is being conducted on interventions for preventing falls in the elderly, wearable devices for detecting falls, and methods for improving the performance of fall detection algorithms. Wearable devices for detecting falls of the elderly generally use gyro sensors. In addition, to improve the performance of the fall detection algorithm, an artificial intelligence algorithm is applied to the x, y, z coordinate data collected from the gyro sensor. In this paper, we develop a wearable device that uses a gyro sensor, body temperature, and heart rate sensor for health management as well as fall detection for the elderly. In addition, we develop a fall detection and health management system that works with wearable devices and a guardian's mobile app to improve the performance of the fall detection algorithm and provide health information to guardians.

This study was performed to analyze health problems in older adults in a comprehensive manner, including usual living habits, nutritional status, and society psychological factors. Research was conducted by a structured questionnaire by interviews with a test group of 316 people over the age of 65 from April 2012 to August 2012. Elderly people's dietary intake was assessed using NSI (Nutrition Screening Initiative) by the 24-hour retrospective method, and elderly people's feeling of helplessness and sense of belonging were assessed using the measuring device. Material analysis, descriptive statistics, and regression analysis were performed using SPSS. Elderly people with increased age showed higher chances of being in the high-risk and undernourished group. Elderly with high NSI showed low intake of fat, protein, fibrin, vitamin C, E, $B_1$, $B_2$, Niacin, K, Fe, Zn, and Cu than those with low NSI. Findings from this comparative analysis indicate that elderly with better nutritional status showed a lower feeling of helplessness than those with poor nutritional status. Overall, elderly people consumed a b road variety of foods, and social emotional stability of elderly people increased at optimal dietary levels.

The purpose of this study were to analyse of craniofacial shape by 3D and to develope of head models for Korean adults with gender and age groups. The 3D measurement technique adapted in this study was a novel approach compared that the same technique has been commonly used in measuring human bodies. The data and the model of head analysis can be used as a basic reference in developing various head related items such as hat, helmet, gas mask, ear phone, and etc. In this study, heads of 836 Korean adults were measured in 3D, analyzed by statistical methods, and modelized in 3D by gender and age groups. From the basic statistical data analysis, vertex-tragion and the length between the pupils were the longest in their twenties for both men and women, and grew shorter in elderly groups. In all categories, a significant difference appeared between men and women in their 20's, but the differences were less noticeable in elderly groups. Compared to the one size standard head model of the Korea Occupational Safety and Health Agency, the above three-dimensional standard head model would provide a more through fit because gender and age groups were sub-divided and analyzed in 3D.

PURPOSE: The respiratory function and range of joint mobility deteriorate due to aging, respectively, and the respiratory function may be related to the range of joint mobility. To the best of the authors' knowledge, there has been little research on how the deterioration of the range of joint mobility caused by aging is related directly to the respiratory function. This study investigated the relationship between the respiratory function and the range of joint motion in the cervical and lumbar regions of older adults. METHODS: Thirty-two older adults participated in the study. The forced vital capacity (peak expiratory flow: PEF and forced expiratory volume in 1 second: FEV1) and the range of cervical joint motion were assessed in all subjects. The results were analyzed using the Pearson's correlation coefficient. RESULTS: The respiratory function moderately correlated with age. A moderate correlation was observed between FEV1 and right cervical lateral flexion. PEF was moderately correlated with the lumbar lateral flexion. In addition, FEV1 correlated strongly with lumbar lateral flexion. CONCLUSION: The respiratory function was correlated with the cervical and lumbar lateral flexion. Therefore, rehabilitation of the respiratory function should involve improving the limited range of motion of the joints, and a stretching program is needed for older adults.

The changes in the corpus callosum (CC) with age and gender remain largely subject to dispute, which might come from the different strategies for analyzing the size and shape of CC. We have investigated this issue by measuring some variables reflecting the spatial orientation of CC on magnetic resonance imaging in Koreans, which minimize individual variances in the brain. The subjects were composed of young adults in their twenties (51 male, 59 female) and elderly adults in their sixties and seventies (60 male, 71 female). The total area of CC, length and height of CC, the central angle and the four angles suggested by Oka et al. were measured. The whole area and the central angle of CC were not significantly affected by age and gender. The height and length of CC were significantly greater in elderly people. The angle connecting genu, upper notch of pons and splenium was significantly larger in the elderly group. Furthermore, all four angles were significantly different between male and female subjects. These results confirm that the spatial orientation of CC is influenced by age and gender.

This study examined household food insecurity and the associations of food insecurity with socioeconomic conditions, food behaviors, and nutrient intakes among 458 older adults(mean age=$73.2{\pm}4.5$) from 5 clusters of low-income areas in Seoul, Korea. Using an adapted version of the USDA short form household food insecurity scale, 63.4% of the households were food insecure(40.7% for food insecure without hunger and 22.7% for food insecure with hunger). The proportion of household was lower on the items measured more severe level of food insecurity. Food insecurity was linearly and negatively associated with food expenditure, food secured period and the degree of nutrition management skills, health status and depression. Food secure older adults had mere of energy and other nutrients from animal resources(riboflavin and animal protein, fat and calcium), but less of carbohydrates than those from the food insecure households. These results suggest household food insecurity measures used in this study was valid as well as food insecurity was prevalent and an important indicator of nutrition well-being among low income elderly persons.

Computerized cognitive training utilized to enhance cognitive function in dementia patients enables them to autonomously execute and acquire tasks while obtaining prompt and precise feedback on their performance. We are designed to highlight the efficacy and clinical relevance of computerized cognitive training programs as therapies for elderly adults with mild dementia. In accordance with the Cochrane Handbook for Systematic Reviews of Interventions, we conducted a review of pertinent literature across various databases, including the Korean Information Service System, Research Information Sharing Service, National Assembly Digital Library, DBpia, and PubMed, encompassing research from 2003 to 2023. Utilizing rigorous inclusion and exclusion criteria, we examined a final sample of 12 research. The data indicated that following computerized cognitive training interventions for senior adults with mild dementia, ADAS-Cog exhibited the most substantial effect size (g=-1.400), succeeded by MMSE (g=0.631), DRS (g=0.522), BNT (g=0.335), and GDS (g=-0.304), ranked by intervention efficacy. The findings allow us to assert that computerized cognitive training programs significantly enhance cognitive function, alleviate depressive symptoms, and improve language abilities in elderly individuals with mild dementia.

The purpose of this study was to analyze the mass media's news framing on the elderly leisure. For this, researchers collected news articles from daily newspapers such as Chosun Ilbo, Hankyoreh, Kyunghyang Shinmun, and analysed the news framing of them through text-analytic approach. Total of 153 news the about elderly leisure between 1990 and 2010 were used for frame analysis. The Frame analyses were divided by formal frame and content frame. The formal frame was formed by deduction based on the classification method of Iyergar(1991) and the content frame was formed by induction according to the analysis of overall themes and titles of news. The main result could be summarized as follows: First, the analysis of formal frame showed that the episodic frame was predominantly high which focused on specific event or occurrences about elderly leisure. Second, it was found by content frame analysis that elderly leisure's facilities, health, serious leisure, policy frame were main subjects of news framing.

Objectives: This study aims to examine factors affecting depression of Older Adults by using the data of the elderly survey conducted by the Korea Institute of Health and Social Affairs in 2020. Methods: The total sample was 4,777 people aged over 65 years old. In this study, sociodemographic variables, information devices'use behavior and discomfort variables were input to examine the effect on depression. The data was analyzed with t²-test, ANOVA and hierarchical regression by SPSS statistic program. Results: First, use behavior and discomfort of information devices and depression were significantly different by sociodemographic variables(sex, age, level of education, marital status). Secondly, regression analysis showed that age and level of education affected an influence on depression in Model 1, which analyzed only sociodemographic variables. However, Model 2, which analyzed devices' use behavior and discomfort variables at the same time, showed that they affected depression. Conclusions: It was suggested to develop customized health education and mental health promotion were needed to reduce depression in the elderly.
