A smart home system improves the elderly's quality of life by monitoring and analyzing their movements and health conditions with better health-care and social support services. Therefore, there has been an effort to adopt a smart home system for the independently living elderly. However, to the best of our knowledge, no study has investigated the usability of a smart home system on actual independently living elderly housing in long-term settings. Thus, this study aims to demonstrate the usability of a smart home system on independently living elders in living lab conditions. The BLE smart band and the BLE receiver were chosen for the smart home system to monitor the movement of the participants in their homes as well as to monitor the heart rates, step counts, sleep index. Nine independent living elderly from the senior welfare center in Kimjae participated in this living lab demonstration experiment for ten months. This demonstration experiment confirmed the effectiveness of low-cost and easily adoptable IoT-based BLE sensor sets on independent living elders and discussed the troubles and limitations of the experiment. By grasping the pros and cons of IoT-based BLE sensor sets, this study seeks to improve the accessibility and usability of smart home systems for the elderly population in independent living arrangements.

Objectives: This study evaluated the effectiveness of Sayeok-san for treating insomnia. Methods: We conducted a search using keywords, such as "Sayeoksan", "Si-ni-san", and "insomnia" in eight databases (CNKI, Wanfang, Pubmed, Embase, Cochrane, NDSL, OASIS, RISS) on July 17, 2012. There was no limit placed on the publication period of the papers, and we used Cochrane's risk of bias tool to assess their quality. Meta-analysis was classified according to the outcome measurements, such as total effective rate and PSQI. Results: Nine RCTs were selected. Meta-analysis showed that the treatment group, which used Sayeok-san, had a higher total effective rate than did the control group that used only Western medicine. The treatment group also had a lower average of PSQI and TSS (TCM symptom score) than did the control group. Conclusion: This study suggests that Sayeok-san is effective in treating insomnia. However, these findings should be interpreted cautiously due to unknown or high risk of bias of the included trials.

Objectives : The purpose of this study is to report a case of erythematotelangiectatic type rosacea and peripheral facial palsy improved by Korean medicine treatment with Soshioho-tang gagambang. Methods : The patient visited our clinic due to facial flushing and peripheral facial palsy symptoms. Based on Sanghallon provision, we treated this case with Soshiho-tang gagambang. The result of treatment was evaluated by Visual Analogue Scale(VAS), Dermatology Life Quality Index(DLQI) and House-Brackmann Grading System(HBGS). Results : After 12 days of taking Soshiho-tang gagambang, VAS of rosacea was decreased from 9 to 4 and DLQI was decreased from 22 to 5. After treatment, rosacea with facial flushing was improved and HBGS was reduced from 3 to 1. Conclusions : This study shows the possibility of taking Soshiho-tang gagambang for erythematotelangiectatic type rosacea and peripheral facial palsy derived from stress, fatigue and sleep disturbance according to Sanghallon provision.

Purpose: This study aims to identify gender-based differences in factors related to smartphone overdependence among middle school students. Methods: The subjects of the study were middle school students who participated in the 16th Korea Youth Risk Behavior Survey (2020). Frequency analysis, the Rao-Scott χ² test, and multiple logistic regression were performed using SPSS 27.0. Results: Identified risk factors were grade level, self-reported health, self-reported happiness, loneliness, smoking, drinking, poor sleep quality, physical activity, and generalized anxiety disorder, which were commonly found in all participants. Additionally, stress was found related only in boys, while the residential area and depression showed associations only in girls. In particular, the more severe was the level of generalized anxiety disorder, the higher was the risk ratio of the high-risk group, compared to the potential-risk group. Conclusion: Based on the findings of the study, a customized strategy that considers gender differences should be developed in order to prevent smartphone overdependence in middle school students.

Purpose: The purpose of this research is to identify factors affecting suicidal ideation of the low-income elderly. Methods: The study subjects were lowest-income(basic living allowance) and lower-income elders who were registered for home visiting services at five District Health Centers in Seoul. Interview data were collected from 280 elders and analyzed. Using SPSS/WIN 21, $x^2$-test and t-test were conducted to analyze the relationship between the subjects' characteristics and their suicidal ideation, and logistic regression was done to identify factors affecting suicidal ideation. Results: Of the subjects, 48.6% had suicidal ideation for the last one year. Self-evaluated psychological status, quality of sleep, depression, and loneliness were affecting factors to the subjects' suicidal ideation. Conclusion: Psychological and social factors are strongly related to the suicidal ideation of the elderly who are living alone in metropolitan areas. Therefore, home visiting services should supply physical, psychological and social cares continuously to the low-income elderly, especially those who live alone in metropolitan areas.

Atopic dermatitis (AD) is a chronic and relapsing inflammatory disease that affects 1%-20% of people worldwide. Despite affecting many people, AD current treatments, such as corticosteroids and calcineurin inhibitors, have not only harmful secondary effects but are also often ineffective. Therefore, natural nontoxic compounds are on high demand for developing new effective AD treatments. Panax ginseng Meyer has been used traditionally for its promising healing and restorative properties to treat many diseases including skin disorders, reason why in this review we want to explore the research performed with AD and P. ginseng as well as determining its potential for new drug development. Previous researches have shown that P. ginseng has positive effects in AD patients such as lower eczema area and severity index, transepidermal water loss, and immunoglobulin E levels and better quality of sleep. In vivo animal models, as well, have shown positive results to P. ginseng and derived ginsenosides, such as the decrease of transepidermal water loss, immunoglobulin E levels in serum, allergy-related cytokines, and downregulation of NF-κB, MAPK, and Ikaros pathways. All of these previous data suggest that P. ginseng and its derived ginsenosides are undoubtedly a nontoxic effective option to treat AD.
