Retention of CPR knowledge was assessed in a group of 86 police officers who participated in first aid and emergency rescue program on February, 2001 and 3 months later. Police officers were taken written test about CPR knowledge by American Heart Association Guidelines 2000 and competence level. Data were analyzed by Frequency, Percentage, Mean, paired t-test using SPSS program. The results for this study were as follows ; 1. In the post-test, the highest question was a rechecking time of circulation sign(98.8%), the lowest was a check for signs of circulation(17.4%), in 3months later, the highest question was a chest compression(94.2%), the lowest was a check for signs of circulation(1.2%), and a retention of CPR knowledge was a 71.7%. In 3months later, knowledge level was decreased compared to that of post-test(t=-9.09, p=.000). 2. In 3months later, the competence level was decreased compared to that of post-test(t=3.09, p=.003).

Objectives : The objective of this study is to assess the prevalence and risk factors of metabolic syndrome (MS) among inpatients with schizophrenia, and to compare with general population. Methods : Nine hundreds seventy inpatients were included to assess the prevalence of MS from two mental hospitals in Yong-in city. Assessment of MS was performed based on modified American Heart Association criteria with abdominal obesity threshold of 90cm for men, 85cm for women. Comparative analysis was performed using age- and gender matched sample from Korea Health and Nutritional Examination Survey III. For evaluating risk factors, analysis included 766 inpatients taking consistent medications at least for 30 days. Results : The prevalence of MS of inpatients with schizophrenia was 26.2%, in females it was 33.2%, compared to 20.2% in males(p < 0.001). Compared to general population, the prevalence of MS was significantly lower in male and higher in female patients. In terms of criteria prevalence, who met abdominal circumference criterion were more prevalent in patient group(p < 0.001). After multivariate analysis, female gender and old age remained as risk factors of MS. Conclusions : The prevalence of MS of inpatients with schizophrenia was 26.2% and significantly low compared to general population. Female gender and old age were risk factors of MS.

Purpose: This study was done to examine the effects and retention of the American Heart Association (AHA)'s basic cardiac life support (BLS) training on knowledge and skills of nursing college students. Method: The study was a one group pretest-posttest experimental design. The sample included 41 junior nursing students from D college who participated in an AHA BLS course for healthcare providers in K hospital from January 18 to June 7, 2010. The instruction was based on ‘BLS knowledge and skills'. The data were analyzed with paired t-test using the SPSS/PC 12.0 win. Result: First, knowledge (t=-7.648, p=.000) and skills (t=-12.988, p=.000) were significantly increased immediately after BLS training. Second, knowledge (t=4.098, p=.000) and skills (t=50.350, p=.000) of BLS after 4 months was significantly decreased compared to right after BLS training. Conclusion: Knowledge and skills were decreased 4 months after BLS training. Therefore, retraining in BLS is required within 4 months. To maintain the knowledge and skills of BLS, appropriate renewal time and retraining programs are needed.

Purpose: The study was done to identify variations in Nurses' CPR knowledge, attitude and performance before and after BLS Education. Method: This study was designed to evaluate the differences in Nurses' CPR knowledge, attitude and performance. For the study we selected 167 nurses working in Daegu K University hospital. The study group was given a test before (pre test) and after (post test) BLS education. The BLS education was given by two BLS instructors certified by the American Heart Association, using a DVD and manikin. Result: The results showed a statistically significant difference the nurse's knowledge, belief, emotion and performance but there was no significant difference in their behavior after BLS education. CPR knowledge and performance was higher among emergency room nurses compared to surgical ward nurses. Conclusion: CPR education has shown to have a positive effect on nurses' attitudes towards CPR. It also improved their related knowledge and performance. Therefore, cardiopulmonary education should be given continuously, and different steps of CPR education programs need to be developed in order to fill the knowledge deficiency gap.

As social media are emerging as essential communication channels for corporates in all areas, luxury jewelry brands have implemented enhanced strategies for brand story videos by creating brand channels on YouTube. In this study, a comparative analysis of the videos made available by Cartier and Tiffany&Co. on their YouTube Brand Channels was conducted, with the aim of identifying their strategic characteristics. The research method encompassed, both literature review and empirical investigations. A quantitative analysis was conducted by means of the 'HEART' model, a type of luxury jewelry brand story, and the following common strategic elements were identified. First, in their brand story videos both brands focus primarily on 'theme'. Second, 'relationship' and 'artisanship' are emphasized in addition to 'theme'. Third, the videos incorporate high level aesthetics to stimulate the fantasies and dreams of their audiences. The strategic differences between the brands are as follows. : First, 'artisanship' is given the greatest significance along with 'theme' in Cartier videos, while 'relationship' has prime significance in Tiffany&Co. videos. Second, a difference between a European approach and an American approach towards luxury brand building is evident, with Cartier hosting exhibitions while Tiffany&Co. provides gala videos instead.

Purpose: This study was undertaken to examine the effects regarding reeducation of cardiopulmonary resuscitation on persistence of nursing students' knowledge, performance, and self-efficacy. Methods: The research design for this study was a repeated experimental design featuring 35 female nursing students. Participants were educated using the standardized cardiopulmonary resuscitation protocol from the American Heart Association. Three months after the initial education, participants received reeducation about cardiopulmonary resuscitation. Knowledge and self-efficacy were measured before the initial education. Knowledge, performance, and self-efficacy were measured immediately after the initial education, 3 months later, and 6 months later. Collected data were analyzed using PASW Statistics 18.0. Results: Knowledge and self-efficacy significantly increased immediately after the initial education; knowledge, performance, and self-efficacy significantly decreased 3 months afterwards. No further decrease occurred until 3 months after reeducation. Conclusion: These results suggest that the duration between initial education and reeducation was insufficient, although the effects of cardiopulmonary resuscitation education were maintained 3 months after reeducation.

Purpose: The purpose of this study was to determine the effectiveness of hands-only CPR education according to the American Heart Association (2015) guideline for undergraduates with severe visual impairment, to provide basic data for expanding the subject of hands-only CPR education among the visually impaired. Methods: Twenty-one students attending four universities in C Province, aged 19 years or older, were enrolled in this study. These students had severe visual impairment and no other disabilities and have never received hands-only CPR education. This study data were collected from December 1, 2017 to January 11, 2018. The accuracy of the participants' technique was measured using Brayden Pro CPR manikin. The data were analyzed using SPSS version 24.0. Results: Hands-only CPR education was effective in increasing confidence and accuracy of chest compression among undergraduates with severe visual impairment. Conclusion: These findings suggest that individuals with severe visual impairment should be given more educational opportunities. Additionally, subsequent studies should develop equipment that helps increase accuracy by using video aids with commentary or other auditory components for the visually impaired.

Purpose: Blunt cardiac injuries (BCI) have a wide clinical spectrum, ranging from asymptomatic myocardial contusion to cardiac rupture and death. BCIs rarely require surgical intervention, but can be rapidly fatal, requiring prompt evaluation and surgical treatment in some cases. The aim of this study was to identify potential factors associated with in-hospital mortality after surgery in patients with BCI. Methods: The medical records of 15 patients who had undergone emergency cardiac surgery for BCI between January 2014 and August 2020 were retrospectively reviewed. We included trauma patients older than 18 years admitted to Regional Trauma Center, Gachon University Gil Medical Center during the study period. Clinical and laboratory variables were compared between survivors and non-survivors. Results: Non-survivors showed a significantly higher Injury Severity Score (p=0.001) and Abbreviated Injury Scale in the chest region (p=0.001) than survivors. American Association for the Surgery of Trauma-Organ Injury Scale Grade V injuries were significantly more common in non-survivors than in survivors (p=0.031). Non-survivors had significantly more preoperative packed red blood cell (PRBC) transfusions (p=0.019) and were significantly more likely to experience preoperative cardiac arrest (p=0.001) than survivors. Initial pH (p=0.010), lactate (p=0.026), and base excess (BE; p=0.026) levels showed significant differences between the two groups. Conclusions: Initial pH, lactate, BE, ventricular injury, the amount of preoperative PRBC transfusions, and preoperative cardiac arrest were potential predictors of in-hospital mortality.

Background: Fractional exhaled nitric oxide (FeNO) is regarded as a potential biomarker for identifying eosinophilic inflammation. We aimed to evaluate the clinical implication of FeNO and its influence on inhaled corticosteroids (ICS) prescription rate in Korean chronic obstructive pulmonary disease (COPD) patients. Methods: FeNO level and its association with clinical features were analyzed. Changes in the prescription rate of ICS before and after FeNO measurement were identified. Results: A total of 160 COPD patients were divided into increased (≥25 parts per billion [ppb], n=74) and normal (<25 ppb, n=86) FeNO groups according to the recommendations from the American Thoracic Society. Compared with the normal FeNO group, the adjusted odds ratio for having history of asthma without wheezing and with wheezing in the increased FeNO group were 2.96 (95% confidence interval [CI], 1.40-6.29) and 4.24 (95% CI, 1.37-13.08), respectively. Only 21 out of 74 patients (28.4%) with increased FeNO prescribed ICS-containing inhaler and 18 of 86 patients (20.9%) with normal FeNO were given ICS-containing inhaler. Previous exacerbation, asthma, and wheezing were the major factors to maintain ICS at normal FeNO level and not to initiate ICS at increased FeNO level. Conclusion: Increased FeNO was associated with the history of asthma irrespective of wheezing. However, FeNO seemed to play a subsidiary role in the use of ICS-containing inhalers in real-world clinics, which was determined with prior exacerbation and clinical features suggesting Th2 inflammation.

The purpose of the present review is to give an overview of the association between alcohol intake and the risk of developing cancer. Two large-scale expert reports; the World Cancer Research Fund (WCRF)/American Institute of Cancer Research (AICR) report from 2007, including its continuous update project, and the International Agency for Research of Cancer (IARC) monograph from 2012 have extensively reviewed this association in the last decade. We summarize and compare their findings, as well as relate these to the public health impact, with a particular focus on region-specific drinking patterns and disease tendencies. Our findings show that alcohol intake is strongly linked to the risk of developing cancers of the oral cavity, pharynx, larynx, oesophagus, colorectum (in men), and female breast. The two expert reports diverge on the evidence for an association with liver cancer and colorectal cancer in women, which the IARC grades as convincing, but the WCRF/AICR as probable. Despite these discrepancies, there does, however, not seem to be any doubt, that the Population Attributable Fraction of alcohol in relation to cancer is large. As alcohol intake varies largely worldwide, so does, however, also the Population Attributable Fractions, ranging from 10% in Europe to almost 0% in countries where alcohol use is banned. Given the World Health Organization's prediction, that alcohol intake is increasing, especially in low- and middle-income countries, and steadily high in high-income countries, the need for preventive efforts to curb the number of alcohol-related cancers seems growing, as well as the need for taking a region- and gender-specific approach in both future campaigns as well as future research. The review acknowledges the potential beneficial effects of small doses of alcohol in relation to ischaemic heart disease, but a discussion of this lies without the scope of the present study.
