The purpose of this study is to clarify the concept of the frail elderly and to obtain theoretical evidence. The research method was conducted using the basic principles for conceptual analysis of Walker and Avant(2005). As a Result of a review of the literature about how to utilize the concept of a frail elderly, frail elderly might be in the intermediate state of health and disease. They can be defined as physically vulnerable in the sarcopenia, inflammation, insulin resistance, and preceding advanced disease, lead to hospitalization, falls, disability, and death. The attributes were physiological, psychological, and socio-environmental and economic factors, so they had multidimensional factors. They were required the assist daily living of another person. Also, their attributes had decreased the amount of recovery time and degree, and exhaustion. The attributes of frail elderly consisted of these facts: dynamic process, multidimensional factors, dependency, vulnerability. The frail elderly was a dynamic process that involves the possibility of change to health and disease, and include physical, mental, cognitive, and social environmental factors. In addition, the frail elderly was difficulty in daily life, physical vulnerability and difficulty in adaption. In conclusion, frail elderly as defined by the results of this study will contribute to the foundation of health care systems, including community visiting nursing to understand the level of frail elderly and systemic management to do not go into long term care.

The coronavirus disease 2019 pandemic has been continuously spreading throughout the world. As of July 15, 2021, there have been more than 188 million confirmed cases and more than 4.06 million deaths. Although the incidence of severe infections is relatively low in children and adolescents compared to adults, a complication called multisystem inflammatory syndrome in children (MIS-C) may occur in some cases at approximately 2-6 weeks after severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2) infection. MIS-C can be seen in patients of various ages, from young infants to adolescents, and may present with diverse clinical manifestations. While fever present in a great majority of patients, symptoms suggesting the involvement of the digestive or nervous system and the skin and mucous membranes (Kawasaki disease-like symptoms) also appear in many cases. Cardiac involvement may also be observed, including left ventricular dysfunction, myocarditis, coronary artery dilatation, and coronary aneurysm. In some cases, hypotension or shock can occur, and mechanical ventilation or treatment in the intensive care unit may be necessary. Fortunately, recovery is generally reported after appropriate treatment. MIS-C is a rare but important complication of SARS-CoV-2 infection in children and adolescents. As such, it is important to recognize the clinical symptoms and provide appropriate treatment at an early stage. In this review, the epidemiology, clinical symptoms, suggested pathophysiology, diagnostic approach, and treatment of MIS-C will be discussed.

Objective : The objective of this study was to present the components of frailty by organizing the definitions of frail elderly and analyzing the tools used to screen them. Methods : This study searched for articles at involved frailty screening assessments in the elderly. Databases including CINAHL, Embase, Medline Complete, and PubMed were searched. The search terms were "assess" AND "frailty" AND "screening" AND ("frail elderly" OR "elderly"). Results : A total of 539 articles were identified by the search and 11 articles were selected. Frailty occurs due to the depressed function of multidimensional factors, and a frail elderly person is defined as one at high risk of health degeneration, functional impairment, and occurrence of disability, and having a high level of threat to life. Seven tools were selected from 11 articles. The most frequently used tool was the frailty phenotype, which was used in five articles (45.4%). The identified components of frailty were physical, activity participation, nutrition, psychological, social, overall health, and age. Conclusion : The results confirmed the definition and components of frailty. This study is expected to contribute to the future development of standardized evaluation tools for screening frail elderly individuals and intervention programs for the management of the frail elderly.

Purpose: The aim of the present study was to investigate toilet terms and pictograms recognized by elders living in Seoul and Incheon. Method: Data were collected from 308 elders by individual interviews using questionnaires. Result: As for the name of places for elimination, those elders responded Hwajangsil 88.3%, followed by Byeonso 49.3% and Dwitgan 44.4%. Most elders preferred Hwajangsil as the term indicating the place for elimination. The mean age of the group preferred Bunso was significantly higher than that of the group preferred Hwajangsil, whereas educational level was higher in the latter group. Of the 256 respondents, 55% preferred the pictogram of international toilet sign, while 34.8% preferred the pictogram of toilet stool. Those with no formal education tended to prefer the pictogram of toilet stool. Conclusion: The term Hwajangsil is suggested for indicating toilet for elders in general. Other terms familiar with residents need to be investigated in the facilities for elders and those terms should be used in combination with Hwajangsil. English toilet signs alone are not recommended for elders. Simple pictograms of toilet stool is suggested for elders with low educational level. Toilet signs for elders need to include both terms and pictograms.

Learning efficiency can be maximized by careful matching of text features to expected reader features (i.e., linguistic and cognitive abilities, and background knowledge). The present study aims to explore whether this systematic principle is reflected in the development of science textbooks. The current study examined science textbook texts on 20 measures provided by Auto-Kohesion, a Korean language analysis tool. In addition to surface-level features (basic counts, word-related measures, syntactic complexity measures) which have been commonly used in previous text analysis studies, the present study included cohesion-related features as well (noun overlap ratios, connectives, pronouns). The main findings demonstrate that the surface measures (e.g., word and sentence length, word frequency) overall increased in complexity with grade levels, whereas the majority of the other measures, particularly cohesion-related measures, did not systematically vary across grade levels. The current results suggest that students of lower grades are expected to experience learning difficulties and lowered motivation due to the challenging texts. Textbooks are also not likely to be suitable for students of higher grades to develop the ability to process difficulty level texts required for higher education. The current study suggests that various text-related features including cohesion-related measures need to be carefully considered in the process of textbook development.

This study was undertaken to determine the degree of quality of life, and factors influencing osteoarthritis in hypertensive elderly 65 years or older patients, using data from the 7th National Health and Nutrition Survey 2018. Totally, 843 subjects were included from a national sample. The SPSS WIN 26.0 program was used to analyze complex samples by applying the Rao-Scott chi-square test, t-test, and multiple regression analysis. Results indicate that quality of life of the hypertensive group with osteoarthritis is significantly lower than the group with only hypertension (t=5.07, p<0.001). Factors affecting the decrease in quality of life of the hypertensive group were age, subjective health status, and activity restrictions, and the explanatory power was 46.1% (F=12.33, p<0.001). In the hypertensive group with osteoarthritis, the effective factors included gender, cohabitation status, economic activity, subjective health status, activity restriction, body mass index, sleep time, stress perception, and depression, and the explanatory power was 44.6% (F=99.82, p<0.001). Subsequent studies showed that in order to improve the quality of life of hypertensive seniors, intervention programs are required to actively accommodate health conditions and minimize activity restrictions. In addition, for the elderly with osteoarthritis and hypertension, it is necessary to include exercise and nutrition education for body mass index management, and the development and intervention of multidisciplinary participation programs to strengthen mental health.

This study was conducted to identify the factors affecting the quality of life of women over 10 years after menopause using data from 2014 to 2019 of the National Health and Nutrition Examination Survey. The subjects were 6,330. The data were analyzed by frequency analysis, t-test and multiple regression analysis using SPSS 25. As a result of the study, the factors affecting the health-related quality of life of women 10 years after menopause were age(F=30.625, p<.001), educational level(F=20.106, p<.001), perceived health status(F=187.925, p<.001, activity limitation(t=201.051, p<.001), arthritis(t=91.131, p<.001), osteoporosis(t=4.709, p=.030), hand grip strength(t=22.151, p<.001), perceived stress(F=32.775, p<.001), and depression(t=20.117, p<.001). The factors accounted for 35.1%(F=110.393, p<.001). In order to improve the quality of life of postmenopausal women, it is necessary to continuously evaluate and improve the factors affecting the quality of life from the early menopause.

Depression is a psychiatric disorder characterized by depressed mood, anhedonia, fatigue, and altered cognitive function, leading to a decline in daily functioning. In addition, depression is a serious and common mental illness not only in an individual's life but also in society, so it must be actively treated. Autophagy is involved in the pathophysiological mechanism of mental illness. According to a recent study, it is known that autophagy-induced apoptosis affects neuroplasticity and causes depression and that antidepressants regulate autophagy. Autophagy is a catabolic process that degradation and removes unnecessary organelles or proteins through a lysosome. And, it is essential for maintaining cellular homeostasis. Autophagy is activated in stress conditions, and depression is a stress-related disease. Stress causes damage to cellular homeostasis. Recently, although the role of autophagy mechanisms in neurons has been investigated, the autophagy of depression has not been fully studied. This review highlights the new evidence for the involvement of autophagy in the pathophysiological mechanisms and treatment of depression. To highlight the evidence, we present results from clinical and preclinical studies showing that autophagy is associated with depression. Understanding the relevance of autophagy to depression and the limitations of research suggest that autophagy regulation may provide a new direction for antidepressant development.

The traffic vulnerable, including elderly pedestrians, have a relatively low walking speed and slow cognitive response time due to reduced physical ability. Although a smart crossing system has been developed and operated to improve problem, it is difficult to operate a signal that reflects the appropriate walking speed for each pedestrian. In this study, a neural network model and a multiple regression model-based traversing speed estimation model were developed using image information collected in an area with a high percentage of traffic vulnerability. to support the provision of optimal walking signals according to real-time traffic weakness. actual traffic data collected from the urban traffic network of Paju-si, Gyeonggi-do were used. The performance of the model was evaluated through seven selected indicators, including correlation coefficient and mean absolute error. The multiple linear regression model had a correlation coefficient of 0.652 and 0.182; the neural network model had a correlation coefficient of 0.823 and 0.105. The neural network model showed higher predictive power.

Background: Due to the rapid aging of the South Korean population, neurological diseases such as dementia are increasing. Many studies have reported that the incidence of dementia is associated with environmental factors along with age. Objectives: This study analyzed the association between cognitive function and ten heavy metals in the body: arsenic, aluminum, chromium, manganese, cobalt, nickel, iron, copper, zinc, and lead. Methods: From 2018 to 2019, a total of 120 participants who suffered from cognitive impairment were recruited for this study. Blood and urine samples were collected and analyzed for heavy metal concentrations using an inductively coupled plasma mass spectrometer. Demographic information was obtained through face-to-face questionnaires completed by a trained investigator. Cognitive function was evaluated with the Korean version of the Mini-Mental State Examination and the Korean version of the Boston Name Waiting Test. The associations between cognitive function scores and heavy metal concentrations were analyzed using multiple logistic regression analysis. Results: The average age of the 120 participants was 72.7 years, and 69.2% were female. The mean of the MMSE-K and K-BNT scores were 22.9 and 37.9, respectively. The geometric mean of aluminum (Al) was 8.42 ㎍/L. MMSE-K was associated with iron (Fe), but the significance was removed in the logistic regression based on 24 points. K-BNT was significantly associated with aluminum and the odds ratio for K-BNT above 38 decreased by 45% as the aluminum concentration increased. Conclusions: The association between aluminum and the K-BNT score indicated that aluminum is associated with language-related cognitive decline. Based on this result, further study will be conducted by considering co-exposure effects of heavy metals including aluminum.
