This study aimed to propose early diagnosis and management of dementia, which is increasing in aging societies, and suggest commercial utilization strategies by leveraging digital healthcare technologies, particularly lifelog data collected from wearable devices. By introducing new approaches to dementia prevention and management, this study sought to contribute to the field of dementia prediction and prevention. The research utilized 12,184 pieces of lifelog information (sleep and activity data) and dementia diagnosis data collected from 174 individuals aged between 60 and 80, based on medical pathological diagnoses. During the research process, a multidimensional dataset including sleep and activity data was standardized, and various machine learning algorithms were analyzed, with the random forest model showing the highest ROC-AUC score, indicating superior performance. Furthermore, an ablation test was conducted to evaluate the impact of excluding variables related to sleep and activity on the model's predictive power, confirming that regular sleep and activity have a significant influence on dementia prevention. Lastly, by exploring the potential for commercial utilization strategies of the developed model, the study proposed new directions for the commercial spread of dementia prevention systems.

In Korea, the population is continuously decreasing due to the decrease in fertility rates. Military troops are continuously decreasing, but soldiers' suicide, mental health care and medicine prescriptions, and inadequate decisions are increasing. In other words, the mental health of the intestines is getting worse. The mental health of the soldiers is a personal problem, but it can also have a big impact on the troops. This is because accidents such as suicide, divorce, and military leave lead to the restriction of the combat power and the deterioration of fraud. Currently, domestic and foreign academics are studying mental health care plans using wearable devices. The Korean military can also use this to objectively measure the mental health of soldiers and use the accumulated big data to predict and measure various situations. In this study, this study suggests mental health care measures for military soldiers using wearable devices, and further research will be conducted smoothly to improve the mental health of our soldiers.
