The quality of life, frailty, economic activity, and other indicators are crucial for assessing older adults' overall well-being and health status. A comprehensive evaluation using this information helps predict the health status of older adults. This study aims to apply and compare machine learning-based prediction models for comprehensive health indicators of community-dwelling older adults. Utilizing data from 4,652 individuals provided by the Aging Research Panel, we assessed various machine learning techniques to fit the predictor variables. Our findings reveal that the LightGBM Regression model performed the best, with an RMSE of 5.082 and an MSE of 25.83. The Gradient Boosting model best predicted current health status, with an RMSE of 0.588 and an R-Square of 0.456. Additionally, the Random Forest model showed strong performance in predicting economic activity participation among older adults. These machine learning-based models offer valuable insights for evaluating health status and predicting economic activity participation, highlighting the importance of employing diverse methodologies for comprehensive predictions.

The purpose of this study was to identify the factors influencing vocational training participation among individuals aged 65 and older in order to enhance their employability. According to the research findings, the educational background and economic activity status of the elderly significantly impact their participation in vocational training. It was confirmed that economic activity and vocational training are closely related to the capacity development and increased employability of the elderly. Moreover, a considerable number of elderly individuals express a continued desire to work, and this group tends to participate more in vocational training. This underscores the importance of promoting vocational training among the elderly and developing suitable models, which holds significant policy implications. Logistic regression analysis revealed that gender, education, economic activity, desire to work, and pension income affect participation in vocational training. This highlights the necessity of formulating specific strategies in government support policies, particularly for those with lower educational backgrounds. Additionally, the study emphasizes the importance of approaches that encourage vocational training participation, especially among those with lower pension income.

The purpose of this study was to examine the mediating effect of self-efficacy in the relationship between perceived family function and depression in the elderly. A self-reported questionnaire was conducted from July 1, 2019 to July 31, 2019, and 296 copies were used for data analysis. For data analysis, frequency analysis, descriptive statistics, and correlation analysis were performed, and a structural equation model was used to verify the effectiveness of parameters. Results, as the main results, first, family function and self-efficacy of the elderly were found to have a negative effect on depression, and it was confirmed that family function had a positive effect on self-efficacy. Second, it was confirmed that there is a mediating effect of self-efficacy between family function and depression in the elderly. Social interventions for improving self-efficacy in the elderly are suggested to be developed in order to reduce depression in the context. A further discussion on this has been presented.

The study attempted a comprehensive assessment of factors affecting health-related quality of life in the young-old and old-old. Data from the Community Health Survey for 5 years from 2015 to 2019 were analyzed. Research Results Health-related quality of life appears to be higher in the elderly than in the late-stage elderly, and various factors such as age, education level, household income, presence or absence of economic activity, presence or absence of moderate physical activity, stress or presence, and subjective health level Has been found to affect health-related quality of life. In particular, good or bad subjective health and subjective oral health had the greatest influence. In terms of the household type, the quality of life was high in young-old adults living in a three-generation household and old-old adults living in a one-generation household. Considering these characteristics, public policy programs should be developed and implemented to help the elderly with successful aging by improving their quality of life.

With a continuous and steep increase in life expectancies, Korean society is expected to enter the aged society by year 2020. And as the number of elderly increases, the burden of medical and health care expenses for them becomes greater in every developed society. Hence, the preventive approach for chronic degenerative diseases remains to be the best solution for the above-mentioned problem and warranting optimal nutrition would be one of the most important approaches. We performed a nutrition survey on 585 older adults of 50 years of age and older, residing in 3 metropolitan areas including Daejun, Daeku and Kwangju. Anthropometry, including body composition analysis based on the bioelectrical impedance analysis using InBody 3.0 and dietary intake survey by semi-quantitative flood frequency questionnaires, were used in collecting data. As one of the most important factors affecting the health and nutritional status of the elderly, we focused on living arrangements. Analyses were performed on the data from 550 subjects only, after excluding statistical outliers. Three hundred and sixty-eight of them(66.9%) were female and the number of elderly(65 years of age and older) was 485. According to the statistical analyses, the female elderly were more vulnerable to malnutrition than the male elderly. And the older they befame, the less adequate they were in nutrient intake. In addition to this, the elderly living alone showed the poorest patterns of nutrient intake and anthropometry. Although the exact effect of living alone could differ among different sex-age groups, the fact that the elderly living alone is vulnerable to malnutrition would remain concrete. This raises the utmost necessity of nutrition intervention to be devised and directed to the targeted population, namely the living-alone elderly from the government level. The intervention may include nutrition education, nutrition counseling and support In forms of meal service by networking the efforts of central as well as local governments to ensure the good health of the Korean elderly.

Objectives: Much attention has been paid to sleep apnea syndrome (SAS) in the elderly because of its high prevalence. It is expected that SAS in the elderly has both similarities and differences compared to SAS in the young or middle-aged populations. The aim of this study was to elucidate the characteristics and consequences of SAS in the elderly. Methods: In this study we included 210 young or middle-aged adults between 23 and 59 years (20 women and 190 men) and 65 older adults between 60 and 83 years of age (16 women and 49 men). Respiratory disturbance indices (RDIs) of the study subjects were more than 5 in an overnight polysomnography. They completed the Epworth Sleepiness Scale (ESS) and Pittsburgh Sleep Quality Index (PSQI). Informations about body mass index (BMI), neck, waist, and hip measurements, and blood pressure were obtained. Results: No difference was observed between older adults with SAS (older SAS) and adults aged under 60 with SAS (SAS aged under 60) in RDI, apnea index, % time of oxygen saturation less than 90%, and PSQI. Obstructive apnea index and oxygen desaturation index (ODI) were lower in older SAS. Compared to SAS aged under 60, lowest oxygen saturation and central apnea index were higher in older SAS, but they were statistically not significant. BMI and neck circumference were significantly lower in older SAS compared to SAS aged under 60. Diastolic blood pressure was lower in older SAS compared to SAS aged under 60 with no difference in systolic blood pressure. Older SAS showed lower scores in ESS than SAS aged under 60. Significant correlation was observed between RDI and BMI in SAS aged under 60, but not in the case of older SAS. The relationships between RDI and neck circumference, systolic and diastolic pressure, and ESS were similar. Conclusions: The elderly with SAS were not over-weight and there was no relationship between body weight and the severity of SAS. Also, the behavioral and cardiovascular effects of SAS were not marked in the elderly, which might be partly explained by decreased ODI and relatively higher lowest oxygen saturation in older SAS. The normal aging process, aside from increased body weight, might contribute to the development of SAS in the elderly with modest complications.

This study was performed to test the socioemotional selectivity theory (SST) with Korean adults. According to SST, perceiving their life as limited, people are motivated to enhance their mood by regulating their mood in such a way to maximize the positive emotions and weaken the negative ones. Being founded on the dialectical constructs which assume the positive and negative sides of emotional experience coexist, Korean adults were supposed to be less motivated to maximize positive emotions and weaken negative emotions. Thus the elderly koreans might regulate emotions not in the direction of maximizing the positive emotions and weakening the negative ones, but in the direction of not being highly aroused. 166 youth, middle-aged, and elderly were asked to rate the frequencies of 31 positive and negative emotions they had experienced during the last month. In addition, they were asked to judge whether they weaken / adapt / maximize their emotions after experiencing positive and negative events. The elderly experienced less positive emotions as well as negative emotions than youth. Youth experienced emotions of high arousal more often than those of low arousal, but the elderly experienced emotions of high arousal less often. The responses of weakening their negative emotions and their positive emotions were largest in the elderly group. On the other hand, the response of maximizing their positive emotions were largest in the youth group. These results show that the elderly maintains emotional stability by weakening both positive and negative emotions of high arousal.

This study aimed to understand the meaning and essence of the experience of bodily change in young-old adults. van Manen's hermeneutic phenomenological method was utilized. Study participants were 11 elderly who 65 to 74 residing in J city. Data were collected from in-depth individual interviews with the participants from July to September 2016. The essential themes were identified regarding the experience of bodily change in young-old adults: 'self-pity about perceived aging', 'myself projected onto others', 'wants to hold on passing of the time', and 'priority on wellbeing than appearance'. The present findings can be used as important basic data for the development of nursing interventions and improving quality of life for young-old adults.
