Purpose: The purpose of this study was to find out the suicidal ideation rate of the elderly including individual and regional factors by sex. Methods: This is secondary analysis study that combines the data of the 2017 Community Health Survey with the e-indicator data set of the National Statistical Office, and a descriptive correlation study. Statistical analysis used hierarchical logistic regression by SAS 9.4. Results: The 11.5% of the elderly had suicidal ideation within the last year, and 18.4% in Chungnam is the highest. Individual characteristics include females, older people, lower education levels, no job or housewife, no spouse, less than seven hours of sleep per day on the average, low subjective health, high subjective stress, and the worse their economic conditions, the more they had suicide ideation. Considering regional characteristics, suicidal ideation tended to increase significantly as the number of hospital beds per 1,000 people and the rate of obesity was lower, the rate of stress perception was higher, and the odds value was small. When both individual and regional factors were considered, the model conformity of the suicidal ideation improved (ICC=0.0814). Conclusion: In order to lower the suicidal rate of the elderly, it seems that both individual and community factors need to be comprehensively approached from the stage of suicidal ideation in the community.

Purpose: This study aimed to explore the meaning of job experiences of fixed night shift nurses participating in a pilot project by a tertiary hospital, and to provide basic information for improving their night shift working environment. Methods: A descriptive qualitative study was conducted using individual interviews in September 2022. Three female nurses who worked fixed night shifts were recruited from a tertiary hospital. Data were analyzed using content analysis. Results: By analyzing the meaning of job experience as a fixed night shift nurse, four categories and nine subcategories were identified. The four categories of job experience of fixed night shift nurses were: expecting an improvement physical health due to predictable working hours, enjoying leisure time due to long off-duty hours, regretting for loosened relationships, and considering a successful settlement of fixed night shift nursing. Conclusion: As night shift work is essential for nurses to provide continuous nursing to patients, it is necessary to develop various strategies to improve the physical health of night shift nurses through fatigue management and good sleep quality, mental health through work-life harmony, and social health through intimate relationships between patients and coworkers.

Urban air mobility (UAM) is emerging as an innovative transportation solution for cities. However, the potential noise impact on urban life must be carefully examined. Continuous exposure to UAM noise, with its unique frequency characteristics and temporal variability, may adversely affect citizens' health by causing sleep disorders, cardiovascular disease, and cognitive impairmenet, particularly in children. NASA has formed a UAM Noise Working Group to study this issue comprehensively. In Korea, the Seoul Metropolitan Government's UAM demonstration project is expected to accelerate related research and development. Scientific analysis, including noise measurement, prediction modeling, and health impact assessment, must be prioritized. Measures to minimize noise should be established based on this evidence, such as optimizing flight modes, developing noise reduction technologies, and establishing new noise management standards. Transparency and social consensus are crucial throughout this process. Expert review and open communication with civil society are necessary to address related concerns. Sharing demonstration project results and providing opportunities to experience UAM noise through digital twin simulations can help address public concerns and build social consensus. Proactively and scientifically tackling noise issues is essential for the sustainable development and successful integration of UAM into daily life.

Objectives : The number of people in Mibyeong state that complain of physical and mental discomfort but without a clear medical diagnosis has rapidly increased, but the conventional medical system is insufficient to care for these people. By establishing an evaluation instrument for Mibyeong state, it will be possible to provide a research base for Mibyeong management system and expand the clinical area of integrative medicine. Methods : Mibyeong Index was designed to measure inconvenience and resilience of subject's complains including four physical symptoms (fatigue, pain, low sleep quality, indigestion) and mental distress include anxiety, anger, depression. A 21-item quality of healthy measure was developed and tested. We used results of a nation-wide stratified sampled adult data in Korea. Results and Conclusions : Mibyeong index had adequate internal consistency, Cronbach's alpha was 0.88 in general population(N=1,110). The correlation between establised quality of life questionnaires (including SF-12 and EQ-D5 VAS) and the Mibyeong index were from 0.468 to 0.493. The national promotion of advanced health for an aging society and original Mibyeong care technology based on traditional Korean medicine can be developed by a self-care system that enhancing health before suffering illness. We expect that this instrument could be contribute to health management of people in Mibyeong state.

Objectives: The purpose of this study was to understand health-promotion behaviors and to find factors associated with the behaviors among Korean-Chinese workers who live in Korea. Methods: The number of Korean-Chinese workers participated in this study was 187, and the sample was chosen using a convenient sampling method. To understand general characteristics, frequencies and percentages were utilized. To examine the seven categories of health-promotion behavior, their average scores were calculated. To explore factors related to health-promotion behaviors, a multiple stepwise regression analysis was performed. Independent variables used for the analysis were self-concept, social support, stress, perceived health status, and demographics. Results: The average score of the seven health-promotion behaviors was 2.35. Of the seven subcategories of health-promotion behaviors, the scores of rest/sleep and self-actualization were relatively higher; the scores of exercise and stress management were relatively lower. Of demographics and four factors of main interest (i.e., self-concept, social support, stress, perceived health status), education level, types of residence, social support, and perceived health status remained statistically significant. Among the four factors, social support had the greatest impact on health-promotion behaviors. Conclusions: This study has two suggestions. First, it is needed to develop strategies, which can help Korean-Chinese workers enhance levels of health-promotion behaviors regarding stress management and exercise. Second, considering the greatest effect of social support on health-promotion behavior, it is necessary to strengthen social support among Korean-Chinese workers.

Purpose: Chronic upper airway obstruction causes hypoxemic pulmonary vasoconstriction, which may lead to right ventricle (RV) dysfunction. Adenotonsillar hypertrophy (ATH) is the most common cause of upper airway obstruction in children. Therefore, we aimed to evaluate RV function in children with ATH. Methods: Twenty-one children (male/female, 15/6; mean age, $92.3{\pm}39.0$ months; age range, 4-15 years) with ATH and 21 healthy age- and gender-matched controls were included in this study. Tricuspid annular plane systolic excursion and RV myocardial performance index were measured by transthoracic echocardiography. Further, the plasma level of N-terminal of probrain natriuretic peptide (NT-proBNP), an indicator of RV function, was determined. Results: The snoring-tiredness during daytime-observed apnea-high blood pressure (STOP) questionnaire was completed by the patients' parents, and loud snoring was noted in the ATH group. The plasma NT-proBNP level was significantly higher in the ATH group than that in the controls ($66.44{\pm}37.63pg/mL$ vs. $27.85{\pm}8.89pg/mL$, P=0.001). The echocardiographic parameters were not significantly different between the groups. Conclusion: We were unable to confirm the significance of echocardiographic evidence of RV dysfunction in the management of children with ATH. However, the plasma NT-proBNP level was significantly higher in the ATH group than that in the control, suggesting that chronic airway obstruction in children may carry a risk for cardiac dysfunction. Therefore, more patients should be examined using transthoracic echocardiography. In addition, pediatricians and otolaryngologists should consider cardiologic aspects during the management of children with severe ATH.
