The human body becomes vulnerable to various diseases due to deterioration in structure and function as it ages. In particular, changes in brain structure weaken the immune system against diseases such as vascular and metabolic neuropsychiatric diseases. In this study, we used a magnetic resonance imaging technique that allows non-invasive observation of brain structures and measurement of how the volumes of the brain, gray matter, white matter, and subcortical regions changes with aging in women aged 65 to 85 years. As a result of our investigation, we observed a significant linear decrease in subcortical regions with age. These results suggest that the changes due to aging in the brain structure area are closely related to neuropsychiatric diseases in old age, and can provide information in understanding the vulnerability of the brain in old age.

It is important to prevent progression of mild cognitive impairment (MCI) to Alzheimer's disease or other dementia. This study was conducted to investigate cognitive-based intervention and its effectiveness for the older patients with MCI through systematic review. Data search was conducted in September 2020, using the Korea Research Information Service (Riss) and KoreaMed. After selection of literatures according to the predefined inclusion criteria, a total of 12 articles were included. It is revealed that the cognitive-based intervention for the older adults with MCI was found to have a positive effect on the various factors including cognitive function, depression, physical health status, quality of life, and communication. However, it is difficult to draw a definite conclusion due to the various intervention strategies and instruments used. Thus, based on the results of this study, we suggest more studies to verify the effectiveness of such programs.

This study was conducted to identify the mental health and quality of life of cardiovascular disease patients by their activities restriction through the second analysis of the 7th KNHANES collected from 2016 to 2018. The subjects of this study were 521 adults with angina or myocardial infarction who had no missing variables among 24,269 subjects. The difference between mental health and quality of life according to the activity restriction was analyzed by Chi-square method and the effect of mental health and quality of life by activity restriction by Logistic regression method using the SAS 9.4 version. The results of the analysis showed that the stress level, the depression for the last two weeks and suicide thought level was high when there was activity restriction, which had a significant effect on mental health. Mobility, selfcare and usual activities were disrupted, and pain/inconvenience and anxiety/depression increased when there was activity restriction, which also showed a significant effect on quality of life. Therefore, it is suggested that the development and operation of effective physical activity promotion program to minimize activity restriction is necessary to improve mental health and quality of life of cardiovascular patients.

Furniture is an essential element in the area of human residence, and the necessity of system furniture suitable for the pursuit of unity in design, which clearly distinguishes the various and flexible arrangements and characteristics of space, is gradually expanding. The elderly population in Korea currently exceeds 15%, and is expected to be close to 40% by 2050. An increasing number of elderly generations are showing different behavioral patterns, such as sharing information, health care, and seeking independence from children. In order to maintain an independent daily life, a stable living environment has become essential, but as a result of a study that safety accidents caused by households increase due to a decrease in cognitive ability and physical ability, the need for a suitable household has increased. Therefore, the biological changes and characteristics of the elderly were investigated, and the concept definition, scope and limitations of system households were studied. In addition, by grasping the changes in the home appliance market and trends in the home appliance market, the design direction of system furniture required by the elderly was presented.

This study aims to develop a patient-specific radiation exposure dose prediction model based on anthropometric data that can be easily measurable during CT examination, and to be used as basic data for DRL setting and radiation dose management system in the future. In addition, among the machine learning algorithms, the most suitable model for predicting exposure doses is presented. The data used in this study were chest CT scan data, and a data set was constructed based on the data including the patient's anthropometric data. In the pre-processing and sample selection of the data, out of the total number of samples of 250 samples, only chest CT scans were performed without using a contrast agent, and 110 samples including height and weight variables were extracted. Of the 110 samples extracted, 66% was used as a training set, and the remaining 44% were used as a test set for verification. The exposure dose was predicted through random forest, linear regression analysis, and SVM algorithm using Orange version 3.26.0, an open software as a machine learning algorithm. Results Algorithm model prediction accuracy was R^2 0.840 for random forest, R^2 0.969 for linear regression analysis, and R^2 0.189 for SVM. As a result of verifying the prediction rate of the algorithm model, the random forest is the highest with R^2 0.986 of the random forest, R^2 0.973 of the linear regression analysis, and R^2 of 0.204 of the SVM, indicating that the model has the best predictive power.

Elementary schools in Korea need to create an environment for integrated education and transform into school facilities that are central to the local community. This study assessed the level of universal design application in the physical environment of elementary schools based on the seven principles of universal design in order to create an environment in which all users, including elementary school students, can access and use school facilities equally. For this aim, field research was conducted on 243 elementary schools, and facilities with low application level were analyzed. As a result of the analysis, in order to apply the principle of 'flexibility in use', the rotating handle on the side of the toilet, which is used by the wheelchair user in the way the toilet is accessed, must be installed in a top-to-bottom rotational manner. In order to improve the applicability of the 'low physical effort' principle, it is necessary to select land and apply the plan from the beginning of the design.

The study aim was to analyze research trends related to the effect of a forest healing program on humans. We analyzed 120 articles by focusing on "Journal information," "Characteristics of study participants," "Program characteristics," "Experimental design," and "Measurement indices." The numbers of papers published in the fields of agriculture and maritime were highest, and the numbers have increased since 1996 when the first paper was published. Many papers have targeted both sex (males and females), middle age, and healthy people. The programs were mainly conducted for multiple times in a forest welfare facility, and exercise therapy, psychotherapy, and plant therapy were primarily administered. Most studies compared experimental and control groups with < 30 participants, and mainly used self-reported surveys. The present study results are expected to be used as basic data for the development of forest healing programs and to expand related research in the future.
