ABSTRACT
AIM: To identify the effectiveness of a combined intervention of 25° upper body elevation and hand massage in patients undergoing radiofrequency catheter ablation. DESIGN: A quasi-experimental study using a non-equivalent control group pre-test-post-test design. METHODS: A total of 46 participants were assigned to an intervention group (N = 21) and a control group (N = 25). To test the effectiveness of the combined intervention, the major variables were low back pain and discomfort, including physical, psychological and environmental factors. RESULTS: The control group had low back pain, and the physical, psychological and environmental discomfort scores increased over time, whereas the experimental group showed low back pain, and the physical, psychological and environmental discomfort scores were statistically significantly decreased. The combined intervention can be applied in clinical practice not only in patients who have undergone radiofrequency catheter ablation but also in those who require an immobile position due to puncture of a femoral blood vessel.

PURPOSE: This study aimed to conduct a scoping review of studies on interventions for the prevention of safety accidents involving infants. METHODS: The scoping review method by Arksey and O'Malley was used to conduct an overview based on information spanning a wide range of fields. Multiple electronic databases, PubMed, CINAHL, RISS, and KISS, were searched for articles written in English or Korean published from 2012 to the present on safety accident prevention interventions. A total of 2,137 papers were found, and 20 papers were ultimately analyzed. RESULTS: Most studies were conducted in the United States (55.0%) and in the medical field (45.0%), and most were experimental studies (35.0%). The results were organized across five categories: 1) preventive precautions, 2) characteristics of children's developmental stages, 3) encouraging voluntary participation, 4) continuity of interventions, and 5) teaching methods. CONCLUSION: Safety accident prevention interventions should cover the establishment of a safe home environment, include voluntary participation, and provide routine follow-up interventions. Additionally, practical training and teaching methods that incorporate feedback rather than a lectureoriented approach should be adopted.
ABSTRACT
A new liquid chromatographic ligand exchange CSP has been prepared by covalently bonding (S)-N,N-carboxymethyl undecyl leucinol monosodium salt onto silica gel and employed in resolving various alpha-amino acids. The new CSP was quite good in resolving various a-amino acids and the resolution results were dependent on the type and content of organic modifier in the mobile phase. From these results, a chiral recognition model using a lipophilic interaction between the tethering alkyl group of the CSP and the substituent at the chiral center of alpha-amino acids was proposed. The liquid chromatographic resolution of alpha-amino acids on the new CSP was also found to be dependent on the Cu(II) concentration in the mobile phase and the column temperature.
