This study investigated the risk factors of hypertension among individuals under and over 65 years of age. A total of 6,152 participants were analyzed using the 6th Korean Longitudinal Study of Aging. The collected data were analyzed by Chi-square tests and logistic regression using SPSS 23. The results showed that the subjective health status, diabetes, heart disease, and degree of obesity according to BMI were risk factors affecting hypertension in individuals both under and over age 65. In adults under age 65, chronic lung disease, digestive disease, and drinking were risk factors affecting hypertension. In elderly over age 65, region, arthritis and rheumatic disease, smoking, and cognitive function were risk factors affecting hypertension. There is a need for chronic disease management in Korea due to rapid aging. In particular, it is important to analyze for effective management age-related risk factors affecting steadily increasing hypertension with age. Therefore, it is necessary to manage chronic disease management through social welfare improvement and welfare plans for the elderly, as well as personal management.

This paper designs and implements a smart care system for the senior citizen who lives alone. Recently, as the level of living has increased due to the rapid improvement of medicine, living standard and environment, the proportion of the elderly population is increasing. In addition, the proportion of the elderly living alone, which is increasing with the aging society, suggests that the provision of services such as the elder care system and emergency notification is becoming an important issue. However, since the existing emergency notification technology analyzes fixed CCTV images, it is difficult to monitor in the blind spot of CCTV and to move to a place where the camera is not installed. There is a problem that it can not be performed. Therefore, in this paper, we design and develop a smart care system that utilizes robot and object tracking technology that can move in real time to overcome these shortcomings. This enables real-time monitoring regardless of the location, and prompts for assistance in case of an emergency, so that it can provide convenience to cares and assistants.

The purpose of this study was to analyze the claim data of Health Insurance Review & Assessment Service to determine what factors affected the length of stay in patients aged 65 and older and undergoing total knee arthroplasty due to the principal diagnosis of gonarthrosis by the type of medical institutions. As a result of making an analysis, gender, age, medical security type, severity, residential area and the number of sickbeds were identified as the factors that influenced the length of stay in each type of medical institutions. At this point in time when an increase in the elderly population triggered by population aging and another subsequent increase in medical expenses put a heavy strain on household and national economy, it's necessary to consider how to shorten the length of stay and how to ensure the efficient management of sickbeds based on the findings of this study. In addition, this study is of significance in that it could be used as basic data on quality life-care for elderly patients by the introduction of a systematic management system geared toward lessening patient burden for medical expenses.

As the world becomes an aging society due to a decrease in the birth rate and an increase in life expectancy, a system for health management of the elderly population is needed. Among them, various studies on occupancy and activity types are being conducted for smart home care services for indoor health management. In this paper, we propose a random forest model that classifies activity type as well as occupancy status through indoor temperature and humidity, CO2, fine dust values and UWB radar positioning for smart home care service. The experiment measures indoor environment and occupant positioning data at 2-second intervals using three sensors that measure indoor temperature and humidity, CO2, and fine dust and two UWB radars. The measured data is divided into 80% training set data and 20% test set data after correcting outliers and missing values, and the random forest model is applied to evaluate the list of important variables, accuracy, sensitivity, and specificity.

최근 우리나라는 유례를 찾아볼 수 없을 정도로 고령화 진행속도가 빠른 나라로 공적 연금재정과 연금제도의 지속가능성에 대한 관심이 증가하고 있는 상황이다. 따라서 사회보장제도 개혁에 성공한 국가로 잘 알려진 스웨덴 사례를 통해 사학연금제도의 유지 및 장기적 재정안정화에 시사하는 바를 찾고자 한다. 스웨덴 정부는 인구고령화에 따른 위험에 상대적으로 안전한 '명목확정기여(Notional Defined Contribution)'방식을 도입하여, 개인의 연금계좌에 연금보험료를 적립하여 수급시점에 본인이 부담한 보험료 상당액을 연금으로 돌려받을 수 있도록 운영하고 있다. 또한 경제상황이 예상 수준보다 침체되고 연금 재정수지가 악화될 경우 이와 연계하여 자동으로 연금가입자의 부담금을 높이고, 지출되는 급여액을 감소시키는 '자동재정균형장치(Automatic Balancing System)'를 도입하였다. 상기와 같이 기여와 급여를 명확하게 연계시키는 스웨덴의 명목확정기여 방식의 연금제도는 장기적 재정안정은 물론이고 안정적인 연금 급여를 제공한다고 평가되고 있다. 스웨덴은 연금개혁 후 확정기여(DC)제도로 전환하여 장기적인 제도 안정성을 추구하지만 사학연금은 확정급여(DB)제도를 유지하면서 급여수준의 하향조정과 보험료율을 점진적으로 상향시켜 재정안정성을 확보하는 것이 가장 큰 차이점이다. 스웨덴의 연금제도와 같이 공적연금의 틀을 유지하면서 사적연금의 장점을 최대로 수용한 명목확정기여 방식의 연금제도를 도입한다면 급격한 재정부담 없이 장기적으로 지속가능한 연금재정 안정화에 기여할 수 있을 것이다. 일견 스웨덴의 정치, 경제상황 및 문화적 특성 차이로 인해 스웨덴의 연금제도 방식을 획일적으로 사학연금제도에 적용하는 것은 불가능하다. 경제상황을 고려한 기여와 급여의 연계 강화를 개혁의 기본방향으로 설정한 스웨덴의 사례를 벤치마킹하여 사학연금 또한 거시경제상황과 조화를 이루는 제도개선 및 자동안정장치를 마련해 보는 것도 고려해 봄직 하다. 지속적으로 스웨덴 및 연금제도 선진 국가들의 연금개혁안을 재검토하여 사학연금제도에 현실적으로 적용할 수 있는 방안과 시사점들을 찾는 노력이 필요할 것이다.

There are countless possibilities lying ahead of us, and while predicting the future may be challenging, it does not render the act of forecasting meaningless. Predicting various possibilities allows us to be flexible in coping with unforeseen circumstances. This study was conducted to explore extreme events (X-events) in the population sector in South Korea. To achieve this, focus group interviews were conducted with 32 emergency planning officers in government and public services. Based on these interviews, significant research findings were derived, indicating that population issues such as population decline and aging could have substantial impacts on various fields, including the economy and national defense. With this study as a catalyst, we anticipate a more active discussion and discourse on X-events that could occur in our society.

This study developed a cognitive impairment predictive model as one of the screening tests for preventing dementia in the elderly by using Automated Machine Learning(AutoML). We used 'Wearable lifelog data for high-risk dementia patients' of National Information Society Agency, then conducted using PyCaret 3.0.0 in the Google Colaboratory environment. This study analysis steps are as follows; first, selecting five models demonstrating excellent classification performance for the model development and lifelog data analysis. Next, using ensemble learning to integrate these models and assess their performance. It was found that Voting Classifier, Gradient Boosting Classifier, Extreme Gradient Boosting, Light Gradient Boosting Machine, Extra Trees Classifier, and Random Forest Classifier model showed high predictive performance in that order. This study findings, furthermore, emphasized on the the crucial importance of 'Average respiration per minute during sleep' and 'Average heart rate per minute during sleep' as the most critical feature variables for accurate predictions. Finally, these study results suggest that consideration of the possibility of using machine learning and lifelog as a means to more effectively manage and prevent cognitive impairment in the elderly.

The purpose of this study was to propose and estimate the architectural planning of general hospital in Korea, for the aged society in the near future. Average life expectancy of Koreans has been lengthened and the percentage of the aged populations is expected to be increased sharply. Therefore, the social problems for the aged occur in various levels, especially in healthcare facilities and medical system due to the weak health conditions of the aged. These problems will become more serious in the near future. However, the architectural planning of general hospital in Korea has not been prepared for the aged society yet. The results of this study were as follows the ward of general hospital should be divided into acute and geriatric wards because of the characteristics of geriatric diseases.

2007년 한국인의 평균 수명은 78.5세(여성 82세, 남성 75세)로 나타났다. 의학의 발달은 세계적으로 노인인구를 증가시키고 있고 이미 우리나라도 유엔이 분류한 고령화 사회로 진입했다. 단순히 얼마나 오래 살았느냐를 나타내는 지표인 '평균수명'보다 건강하게 얼마나 살았느냐를 나타내는 지표인 '건강수명'이 더 중시되는 시대가 된 것이다. 건강수명 중에서도 '눈의 건강'은 젊게 사는 인생의 중요한 잣대이며 이에 따라 나이가 들면서 생기는 증상 중 하나인 노안에 대한 관심도 높아지게 됐다. 여기서 한 가지 주목할 점은 평균수명이 늘어나도 노안이 찾아 오는 시기는 45세에서 오히려 내려가고 있다는 점이다. 대개 45세 전후가 보편적이나 이전에 비해 30대 후반에 노안이 찾아오는 경우가 늘어나고 있는 것이 현실이다. 노안은 가까운 거리의 물체가 잘 보이지 않는 증상으로 노인들에게 흔히 나타나는 증상 중 하나였으나 최근엔 30대 후반에도 빈번하게 나타나고 있으니 적절한 관리와 주의가 요망된다. 그렇다면 노안의 증상과 치료방법에는 어떠한 것들이 있는지 알아보자.
