Smartphone Use Guidance Experiences of Parents of Elementary School Students / 정신간호학회지

Purpose@#The purpose of this study was to understand smartphone use guidance experiences of parents elementary school students. @*Methods@#Qualitative data were collected from 10 parents of elementary school students through individual in-depth interview from January 2022 to February 2022. Collected data were analyzed using the Colaizzi’s phenomenological method. @*Results@#The following four categories were derived from in-depth interviews: ‘Ambivalence on children's smartphone use’, ‘Limitations of guidance competence’, ‘Strategy for guidance’, and ‘New insights and challenges’. @*Conclusion@#This study confirmed that parents of elementary school students were experiencing insight and growth in the process of constantly thinking, trying new strategies, and struggling while guiding their children’s smartphone use. Parental education on elementary school students' smartphone use guidance should include comprehensive contents that could check awareness and principles of useful smartphone use and enable effective guidance tailored to the child's developmental characteristics.

Experiences of Spouses of Patients with Hematologic Malignancies: Finding a Way to Get Out of the Endless Tunnel

PURPOSE: This study was to explore experiences of spouses with hematologic malignancy patients. The main question was "What are experiences of spouses whose husband or wife was diagnosed with hematologic malignancy?". METHODS: Participants for this study were 12 spouses. Data were collected through individual in-depth unstructured interviews with participants from Feb, 2014 to June, 2015 and analyzed using Strauss and Corbin's grounded theory methodology RESULTS: A core category was 'Finding a way to get out of the endless tunnel'. The process is 1) Shock, 2) Confusion, 3) Struggle, 4) Living with the disease, 5) Maturation within the disease. The contextual conditions were 'Responsibility for patient', 'Fear of spouseless future'. The intervening conditions were 'Having support', 'Having closer marital relationship', Keeping patient's disease repressed. Finally, Participants reached 'Circling around the disease', 'Finding personal growth'. CONCLUSION: The results of this study could help understand the experiences of spouses of hematologic malignancy patients. The emerged process of their experiences gives a framework to develop strategies to help spouses to overcome disease.

Effect of Attractor Construction Methods to Fractal Dimension for Heart Sound Analysis / 대한의료정보학회지

Strange attractor can be constructed from time series data such as heart sound. In the areas of the recognition and diagnosis of abnormal heart sounds, signal presentation method is very useful because good features can be detected from good presentation. This paper examines efficiency in diagnosing abnormal heart sounds of the two different methods for constructing attractor. Nine different heart sounds from typical clinical conditions were used for this study. The first method was constructing attractors using original heart sounds, and the second was modifying the original sounds by autocorrelation and they were then applied to the orignal sounds as to cross correlation checks. Attractors could be constructed using signals generated by these methods, and values of fractal dimensions would then be calculated which has been a well known method to measure characteristics of attractors. The results showed that the second method appeared to provide more efficient way to correctly classify abnormal heart sounds.
