Objectives: This study examined the nutritional status according to frailty status in the elderly at home. Methods: The participants were a total of 76 elderly at home living in Seo-gu, Gwangju, Korea. The nutritional status and frailty status were analyzed using the Nutrition Quotient for Elderly (NQ-E) and the Korean version of the Fatigue, Resistance, Ambulation, Illnesses and Loss of weight Scale (K-FRAIL), respectively. Results: The distribution of frailty status was robust (17.1%), pre-frailty (38.2%) and frailty (44.7%), and its distribution was significantly different in genders, age groups and the number of medications. The mean NQ-E score was 47.0 for total subjects, indicating a low grade. The scores of balance, diversity and dietary behavior factors were within the low grade, while the score of the moderation factor was within the medium-high grade. According to the frailty status, pre-frailty and frailty showed significantly higher scores for sugar-added beverages intake in the moderation constructs than robust. Robust showed significantly higher scores for the exercise hours and perception level for one's health than pre-frailty and frailty. Conclusions: These results suggest that nutrition status is associated with frailty status. Regular nutrition education and visiting nutrition service should be established to improve the balance and diversity of food intake and improve the dietary behavior of the elderly at home.

Purpose: Since coronavirus disease 2019 (COVID-19) spread around the world, non-face-to-face services have emerged as the new normal. The functioning of children with developmental disabilities and cerebral palsy improves when parents, therapists, and institutions cooperate. We aimed to investigate the difficult environment of pediatric physical therapy caused by COVID-19, and grasp parents' perceptions of home exercise programs. We intend to design home exercise programs for pediatric treatment in the future and create a non-face-to-face pediatric rehabilitation service system based on our findings. Methods: The first survey was conducted on 30 parents who had children with cerebral palsy and developmental disabilities. It was produced after consultation with relevant experts and discussion with the research team, based on a survey conducted in a previous study. The second survey was produced by revising and supplementing the opinions of parents who completed the first survey and consulting experts. Thereafter, an online survey was conducted on 118 parents who had children with cerebral palsy and developmental disabilities. Results: 61.01 % of the parents reported that they were anxious or afraid for their children to be treated for infectious diseases. 83.90 % of the parents reported that the role of parents had increased. 50.00 % of the parents complained of a lack of skill. 85.59 % of the parents reported that they needed a home exercise program provided by the organization. As a non-face-to-face exercise management method, 35.59 % of the parents wanted a real-time video recording electronically mailed to them, and 34.75 % wanted real-time education using video conferencing programs such as zoom. Conclusion: The threat of COVID-19 has further emphasized the importance of social cooperation and management, leading organizations to enter a new era of non-face-to-face rehabilitation services. It is necessary to collect and systematize related studies to reflect more diverse opinions and improve the perceptions of therapists and parents.

As infrastructure ages and traffic load increases, serious public concerns have arisen for the well-being of bridges. The current health monitoring practice focuses on large-scale bridges rather than short span bridges. However, it is critical that more attention should be given to these behind-the-scene bridges. The relevant information about the construction methods and as-built properties are most likely missing. Additionally, since the condition of a bridge has unavoidably changed during service, due to weathering and deterioration, the material properties and boundary conditions would also have changed since its construction. Therefore, it is not appropriate to continue using the design values of the bridge parameters when undertaking any analysis to evaluate bridge performance. It is imperative to update the model, using finite element (FE) analysis to reflect the current structural condition. In this study, a FE model is established to simulate a concrete culvert bridge in New South Wales, Australia. That model, however, contains a number of parameter uncertainties that would compromise the accuracy of analytical results. The model is therefore updated with a neural network (NN) optimisation algorithm incorporating Monte Carlo (MC) simulation to minimise the uncertainties in parameters. The modal frequency and strain responses produced by the updated FE model are compared with the frequency and strain values on-site measured by sensors. The outcome indicates that the NN model updating incorporating MC simulation is a feasible and robust optimisation method for updating numerical models so as to minimise the difference between numerical models and their real-world counterparts.

Early detection of mild cognitive impairment can help prevent the progression of dementia. The purpose of this study was to design and validate a machine learning model that automatically differential diagnosed patients with mild cognitive impairment and identified cognitive decline characteristics compared to a control group with normal cognition using resting-state quantitative electroencephalogram (qEEG) with eyes closed. In the first step, a rectified signal was obtained through a preprocessing process that receives a quantitative EEG signal as an input and removes noise through a filter and independent component analysis (ICA). Frequency analysis and non-linear features were extracted from the rectified signal, and the 3067 extracted features were used as input of a linear support vector machine (SVM), a representative algorithm among machine learning algorithms, and classified into mild cognitive impairment patients and normal cognitive adults. As a result of classification analysis of 58 normal cognitive group and 80 patients in mild cognitive impairment, the accuracy of SVM was 86.2%. In patients with mild cognitive impairment, alpha band power was decreased in the frontal lobe, and high beta band power was increased in the frontal lobe compared to the normal cognitive group. Also, the gamma band power of the occipital-parietal lobe was decreased in mild cognitive impairment. These results represented that quantitative EEG can be used as a meaningful biomarker to discriminate cognitive decline.

Objectives: The purpose of this study is to analyze the effectiveness of Guibi-tang that are used for postpartum depression. Methods: We searched on five databases [Korean studies Information Service (KISS), Oriental medicine advanced searching integrated system (OASIS), The Cochrane Library, PubMed, and China national knowledge infrastructure (CNKI)] with keywords for Postpartum depression (English, Korean, and Chinese) and evaluated the risk of bias. Meta-analysis was performed on the selected studies. Results: 8 potentially relevant articles were retrieved for further evaluation. There was evidence that Guibi-tang compared with Western medicine was significantly higher rate in total effect rate (RR 1.20, 95% CI 1.04, 1.39, p=0.01). Also, the combined therapeutic effects of Guibi-tang and Psychological intervention compared with Psychological intervention were statistically significant in total effect rate (RR 1.14, 95% CI 1.05, 1.24, p=0.002). And they showed improvement on scores of HAMD (Hamilton depression scale, HAMD) and SF-36 (36-Item short form health survey, SF-36). Conclusion: Guibi-tang appears to be more effective compared to Western medicine in the treatment of postpartum depression. The combination Guibi-tang and Psychological intervention was more effective than psychological intervention alone treated for postpartum depression. However, since unclear risk of bias, the result of this study should be considered carefully. Further clinical trials should be carried out in order to academical clinical progress regarding treatment of Postpartum Depression.
