Influence of Nurses' Work Environment, Organizational Commitment, and Nursing Professionalism on Turnover Intention of Nurses in Long Term Care Hospitals / 간호행정학회지

PURPOSE: The study was undertaken to investigate influence of nurses' work environment, organizational commitment, and nursing professionalism on turnover intention of nurses working in long term care hospitals. METHODS: The study was cross-sectional study. Participants were 199 nurses working in one of 7 long term care hospitals. Data were collected from May 1 to June 30, 2016 and analysed using two stage hierarchial regression analysis with SPSS 22.0. RESULTS: There was a statistically significant difference in turnover intention according to age (F=6.23, p < .001), present work career (t=−2.11, p=.036), frequency of night duty (t=−3.53, p=.001), and present position (t=−4.07, p < .001). The significant predictors of turnover intention were attachment (β=−0.29, p=.005), nursing professionalism (β=−.21, p=.030), identification (β=−.21, p=.014), continuance (β=−.19, p=.008), collegial nurse-physician relations (β=−.16, p=.039), and originality of nursing (β=.16, p=.014). These factors explained 50.4% of the variance. CONCLUSION: The results suggest that several points need to be considered in order to reduce turnover intention in long term care hospital nurses. These points include building work environments to improve collegial nurse-physician relations, promoting recognition of nurses' organizational commitment, nursing professionalism and the political efforts of organizations supporting nursing originality.

Application of DNA chip techniques for Yq microdeletion analysis in infertile males

Our aim was to apply DNA chip technology as a diagnostic tool in infertility research and clinics. Six loci, including a sex-determining region on the Y chromosome and five sequence-tagged sites in azoospermia-factor regions were investigated in infertile male patients. Our method produced a sensitive signal, which showed the presence or absence of the STS regions on the Y chromosome. The results from 93 patients with non- obstructive azoospermia, oligoathenoteratozoospermia, or oligozoospermia were identical when analyzed with either the DNA chip technique or conventional PCR-gel electrophoresis. We have demonstrated its application in the molecular diagnosis of male infertility. This system provides an economic and high-throughput method for detecting the deletion of genomic DNA sequences of large groups of infertile patients, and a completely new approach to male infertility screening. The application of DNA chip technology to identify Yq deletions can also facilitate our understanding of male infertility.
