Background: Extracorporeal membrane oxygenation (ECMO) is an intervention for severe heart and lung failure; however, it poses the risk of complications, including gastrointestinal bleeding (GIB). Comprehensive analyses of GIB in patients undergoing ECMO are limited, and its impact on clinical outcomes remains unclear. Methods: This retrospective study included 484 patients who received venovenous and venoarterial ECMO between January 2015 and December 2022. Data collected included patient characteristics, laboratory results, GIB details, and interventions. Statistical analyses were performed to identify risk factors and assess the outcomes. Results: GIB occurred in 44 of 484 patients (9.1%) who received ECMO. Multivariable analysis revealed that older age (odds ratio [OR], 1.04; 95% confidence interval [CI], 1.01-1.06; p=0.0130) and need to change the ECMO mode (OR, 3.74; 95% CI, 1.75-7.96; p=0.0006) were significant risk factors for GIB, whereas no association was found with antiplatelet or systemic anticoagulation therapies during ECMO management. Half of the patients with GIB (22/44, 50%) underwent intervention, with endoscopy as the primary modality (19/22, 86.4%). Patients who underwent ECMO and developed GIB had higher rates of mortality (40/44 [90.9%] vs. 262/440 [59.5%]) and ECMO weaning failure (38/44 [86.4%] vs. 208/440 [47.3%]). Conclusion: GIB in patients undergoing ECMO is associated with adverse outcomes, including increased risks of mortality and weaning failure. Even in seemingly uncomplicated cases, it is crucial to avoid underestimating the significance of GIB.

Purpose: This study aims to compare and analysis job stress, patient safety culture, and patient safety management activities of nurses in comprehensive nursing care service wards and general wards. Methods: Through an online survey conducted on nurses with more than three months of working experience at five general hospitals in the metropolitan area, 156 participants's data were used for 𝜒²-test, t-test, ANOVA using SPSS ver. 26.0. Result: There were no significant differences in the nurses' job stress and patient safety management activities between the comprehensive nursing care service wards and general wards. However, the patient safety culture of nurses in the comprehensive nursing care service ward was significantly lower than that of general ward. Conclusion: Patient safety culture should be promoted through continuous regular patient safety education, training, and organizational support to increase patient safety management activities. Additionally, institutional programs should be prepared to reduce job stress of nurses at the frontline of patient safety.

Purpose: Early sexual intercourse is associated with poor health outcomes in adolescents. It is known that sexual intercourse coincides with other health risk behaviors such as smoking, drinking, and using drugs. The purpose of this study is to identify the relationships between sexual intercourse and health risk behaviors among Korean and US adolescents using nationally representative data. Methods: Data were collected from the 2011 Korea Youth Risk Behavior Web-based Survey (29,676 students) and 2011 Youth Risk Behavior Surveillance System (10,135 high school students). Logistic regression analysis was performed. Results: In Korea, students who had sexual intercourse accounted for 7.0% in total. Among these, 9.7% were male and 4.2% were female students. In the US, a total of 51.3% students had sexual intercourse, and the proportion of the US male (49.3%) and female (53.4%) students who had sexual intercourse was similar. Korean and US students who experienced sexual intercourse were more likely to smoke, drink alcohol, and use drugs. Conclusion: Since the results of this study show the relationships between sexual intercourse and health risk behaviors, it is necessary to develop comprehensive sex education programs with effective strategies to reduce health risk behaviors in adolescents.

The high sensitivity C-reactive protein (hs-CRP) as one of the typical acute phase reactants is used for predictive factor of the cardiovascular disease and diabetes mellitus. In addition, there are claims that must be included as factors of metabolic syndrome. This research examined the relationship between the concentration of hs-CRP in blood and risk factors of the metabolic syndrome by gender, and the rates of metabolic syndrome depending on the hs-CRP level based on the general public who took the comprehensive medical check-up at Chonbuk National University Hospital in the Jeonbuk province. The subjects aged 17-87 years were participated, and 2,000 people were included as the final subjects except the persons with more than 10 mg/L of the hs-CRP of blood level. The hs-CRP concentrations increased according to the number of risk factors of metabolic syndrome in both men and women. In regards to the risk ratio of metabolic syndrome based on hs-CRP level in blood according to gender, the risk ratio increased by 3.07 times in male and 4.55 times in female intermediate risk group and 3.60 times in male and 6.15 times in female high risk group compared to hs-CRP low risk group. As a result, there was a proportional relation between hs-CRP level and the occurrence of metabolic syndrome, and it occurs more frequently among women than men.

One of the most effective methods to consistently ensure the safety of a tap water supply can be achieved by application of a comprehensive risk assessment and risk management approach for drinking water supply systems. This approach can be termed water safety plans(WSP) which recommended by WHO(world health organization) and IWA(international water association). For the introduction of WSP into Korea, 150 hazards were identified all steps in drinking water supply from catchment to consumer and risk assessment tool based on frequency and consequence of hazards were developed. Then, developed risk assessment tool by this research was implemented at a water treatment plant($Q=25,000m^3/d$) to verify its applicability, and several amendments were recommended; classification of water source should be changed from groundwater to stream to strengthen water quality monitoring contaminants and frequencies; installation of aquarium to monitor intrusion of toxic substances into raw water; relocation or new installation on-line water quality analyzers for efficient water quality monitoring; change of chlorination chemical from solid phase($Ca(OCl)_2$) to liquid phase(NaOCl) to improve soundness of chlorination. It was also meaningful to propose hazards and risk assessment tool appropriate for Korea drinking water supply systems through this research which has been inconsistent among water treatment authorities.

PURPOSE: This study examined the prevalence and specific risk factors in males aged 40-49 years with the coexistence of age-related loss of skeletal muscle mass and obesity (CALSMO). METHODS: The current study analyzed the data obtained from a cross-sectional study involving a sample of 1,218 men who resided in the community and fell within the age range of 40 to 49 years. Multiple risk factors were examined: age, height, weight, body mass index, waist circumference, skeletal muscle mass index, smoking and drinking habits, systolic and diastolic blood pressure, fasting glucose levels, and triglyceride and cholesterol levels. All data were analyzed via complex sampling analysis. RESULTS: The coexistence of age-related loss of skeletal muscle mass and obesity in males was 2.94% (95% CI: 2.06-4.17). The clinical risk factors were low height, high weight, body mass index, waist circumference, skeletal muscle index, systolic blood pressure, diastolic blood pressure, and fast glucose (p < .05). CONCLUSION: The study identifies the prevalence and risk factors for CALSMO among adults in the community. These findings contribute to the existing literature on CALSMO and highlight potential risk factors associated with CALSMO development in males aged 40-49 years.

기후변화로 이상강우 발생이 증가하고 있으며, 매년 폭우로 인한 피해 강도와 규모가 커지고 있는 실정이다. 또한, 폭우의 발생 빈도가 잦아지면서 폭우가 연속적으로 발생하는 경우도 많아지고, 이로 인해 도심지역에서는 전에는 없던 큰 침수 피해가 발생하고 있다. 하천과 해안 인근 지역이 불투수 지역일 경우에 강우강도가 높아질수록 최대 흐름이 급격히 높아지기 때문에 유역특성을 고려한 종합적인 침수위험도 평가가 필요하다. 본 연구에서는 지하철 역사의 침수방지 대책으로 평가요소에 대한 점수를 부여하여 침수위험도 평가를 분석하였다. 종합적인 평가 지수를 고려한 침수 위험도 평가 과정을 거쳐 과거 침수가 발생한 유동인구 및 교통량이 많은 5개의 도시철도역에 대한 침수 위험도 평가를 실시하였다. 이를 종합적으로 분석하여 침수위험 등급(1~4등급)을 설정함으로써 위험등급에 맞는 침수대책을 수립해야 할 것으로 판단된다.
