Apartment buildings are becoming taller and more densely populated with the advancements in science and the development of cities, Consequently, various amenities and safety facilities are being developed to improve the quality of life for residents. However, according to statistics, the number of casualties in apartments accounts for a high proportion of accidents, and the leading cause of the casualties is smoke emitted from fires while sleeping at night. Although it is best to install separate indoor facilities in apartments to minimize smoke damages to occupants, it is useful to minimize the smoke damages by utilizing the installed facilities while reducing the financial burden of occupants. Based on the review, the heat exchanger ventilation system and the kitchen collective exhaust system were selected, and the feasibility of these systems was verified through fire simulation. From the verification results, the available safe egress time improved by 27, 30, and 35 s on the 25th, 35th, 50th floors, respectively.

The purpose of this study was to investigate the factors influencing suicidal ideation among the elderly over 60 years old living in the community centered on sleep and depression. A total of 210 elderly people living in a metropolitan city were surveyed about suicidal ideation, sleep pattern (sleep time, quality of sleep) and depression. Data analysis showed that 14.3% of the subjects were seniors with a high suicidal ideation, 23.3% were sleeping less than 5 hours, 17.6% were poor sleep quality, and 33.3% were depressed. According to multiple logistic regression analysis, the factors influencing suicidal ideation were identified as depression (OR=6.889, 95% CI=2.679-17.712), sleep quality (OR=3.770, 95% CI=1.469-9.679), and gender (OR=3.080, 95% CI=1.266-7.491). These three factors accounted for 31.6% of suicidal ideation variables. Based on the results of this study, it is suggested that reducing the depression and improving the quality of sleep in consideration of gender should be an essential strategy for the elderly in the community to reduce the suicidal ideation.

This study aimed to investigate the association of lifestyle with the copy number of periodontal pathogens. This retrospective study collected electronic health records of 102 subjects with periodontitis, including reports of bacterial genetic tests and lifestyle questionnaires. The five pathogens were analyzed as follows: Porphyromonas gingivalis, Tannerella forsythia, Treponema denticola, Prevotella intermedia, and Fusobacterium nucleatum. The lifestyle questionnaire included age, sex, oral hygiene management, smoking, drinking, exercise, dietary, snacks, water intake, and sleeping time. An independent t-test or ANOVA was performed to compare the copy number of periodontal pathogens according to lifestyle (α=0.05). The copy numbers of P. gingivalis and F. nucleatum were significantly higher than those of other strains. The copy number of T. forsythia in patients who exercised was 54% lower than in those who did not (p=0.009). Other lifestyle factors did not affect the number of bacteria. Exercise habits among the lifestyles showed a association with the number of specific oral bacteria. This result suggests that a lifestyle questionnaire is essential in clinical situation and necessary to prevent and treat the periodontal disease effectively.

Objectives: To compare the vital sign stability and cost of two commonly used sedatives, midazolam (MDZ) and dexmedetomidine (DEX). Patients and Methods: This retrospective study targeted patients who underwent mandibular third molar extractions under intravenous sedation using MDZ or DEX. The predictor variable was the type of sedative used. The primary outcome variables were vital signs (heart rate and blood pressure), vital sign outliers, and cost of the sedatives. A vital sign outlier was defined as a 30% or more change in vital signs during sedation; the fewer changes, the higher the vital sign stability. The secondary outcome variables included the observer's assessment of alertness/sedation scale, level of amnesia, patient satisfaction, and bispectral index score. Covariates were sex, age, body mass index, sleeping time, dental anxiety score, and Pederson scale. Descriptive statistics were computed including propensity score matching (PSM). The P-value was set at 0.05. Results: The study enrolled 185 patients, 103 in the MDZ group and 82 in the DEX group. Based on the data after PSM, the two samples had similar baseline covariates. The sedative effect of both agents was satisfactory. Heart rate outliers were more common with MDZ than with DEX (49.3% vs 22.7%, P=0.001). Heart rate was higher with MDZ (P=0.000). The cost was higher for DEX than for MDZ (29.27±0.00 USD vs 0.37±0.04 USD, P=0.000). Conclusion: DEX showed more vital sign stability, while MDZ was more economical. These results could be used as a reference to guide clinicians during sedative selection.
