Background/Objectives: The purpose of this study was to provide basic data for preparing an appropriate and correct dietary supplement management program by examining the correlation between hypertension and dietary supplements intake. Methods/Statistical analysis: Using the 2019 KNHANES VIII-1 data, the prevalence of hypertension and the intake of dietary supplements for 2 weeks in the past year were statistically analyzed by age, sex, house income and education level. Findings: High blood pressure was the highest with ' Yes ' at 18.9%, and ' No ' at 1.0%. A person with a ‘yes’ of hypertension took dietary supplements for at least 2 weeks in the past year (58.6%). Improvements/Applications: Based on this study, we intend to use it as a guideline for follow-up studies on the High Blood Pressure and whether dietary supplements are consumed according to the guidelines of education on the recognition of the benefits and harms of diseases.

Background: Confirmed coronavirus disease 2019 (COVID-19) patients sometimes require emergency surgery, but protecting healthcare workers and other patients from infection is a high priority. This report describes two cases where surgeries were performed in a hospital without a negative-pressure operating room. Case: Two patients diagnosed with COVID-19 required emergency surgery in a negative-pressure isolation room. Two operating rooms were designated an operating room and an anteroom, and the central air conditioning system was turned off. The disinfection exhaust fan of the operating room was used to create a negative-pressure environment (–1.0 Pa). Conclusions: Performing surgery on COVID-19 patients remains challenging in hospitals not specialized for infection. It is necessary to share experiences between hospitals, and changing the pressure inside the operating room from positive to negative pressure with a simple maneuver is a good option for protection.

The purpose of this study is to investigate the efficiency of safety awareness of VR experience programs for marine safety and the participants’ re-participating behavior. This would emphasize the need for maritime safety experience education, and contribute to preparing basic data for diversification of maritime safety VR contents. From June to August 2021, five of maritime safety experience facilities were visited to target users of VR programs. A total of 350 data were collected using the convenient sampling method, and 295 data were finally used for data analysis. As a result, VR experience for maritime safety had a positive effect on the participants' maritime safety awareness and re-participation behavior. This study could be meaningful in terms of highlighting the need to develop safety programs, and to expand education in South Korea, where three sides are the sea. In addition, this study emphasized the necessity of producing and operating various contents and programs based on VR.

Background/Objectives: This study aims to present basic data for developing an intervention strategy to prevent safety accidents in medical institutions of Korea. Methods/Statistical analysis: Data collection was conducted for 197 health workers at four hospitals in 2021. Data analysis was performed using frequency, percentage, independent t-test, ANOVA, Scheffe's test, Pearson's correlation, and multiple regression. Findings: The educational background (p<.051), work experience (p<.05), and salary level (p<.05) were found to have a significant effect on the awareness, and the explanatory power was 10.5%. The educational background (p<.001), work experience (p<.05), and salary level (p<.05) had a significant effect on the knowledge and the explanatory power was 13.8%. Improvements/Applications: In the future, it is necessary to develop an intervention program to increase the awareness level and response knowledge of safety accidents among medical institution workers, and repeated studies are needed to identify factors that affect this.

Background/Objectives: This study is a qualitative study that attempted to explore the experiences of nursing students participating in the learning community in the COVID-19 situation through the content analysis method. Methods/Statistical analysis: Data collection was conducted for 10 nursing students in 2021 The data analysis of this study was analyzed using content analysis based on the recorded data of the in-depth interview and the transcribed data. Findings: Four categories and eighteen sub-area themes were derived from the research question. Students' online learning community activities were classified into the stages of planning, implementation, evaluation, and reflection. Improvements/Applications: In the future, it is necessary to develop the online learning community program based on active interaction and verifying the effectiveness.
