Purpose: The purpose of the study was to explore how hospital nurses decide to quit working as professional nurses using the grounded theory method. Method: The data was collected by individual in-depth interviews with 12 hospital nurses who recently resigned from work and it was analyzed using 'constant comparative analysis.' Result: The core category that emerged was "in search of new balance with self, work, and family". Three stages were identified: 1) "unconditionally accepting the working situation of itself," 2) "weighing advantages and disadvantages of working as a hospital nurse", and 3) "redesigning a future". Each stage contains three major strategies. The major strategies of the first stage are "maintaining a learning attitude", "enduring physical burnout," and "enduring unfair interpersonal relationships". The second stage contains "identifying advantages of working", "identifying disadvan- tages of working, and "comparing the advantages with the disadvantages". Lastly, the third stage includes "reassessing the aim of life", "beginning to construct an alternative life", and "deciding to quit working at a certain point". Conclusion: The results of the study will help nursing administrators in designing and implementing an effective turnover prevention program for nurses by understanding more deeply the process of turnover phenomenon among hospital nurses.
Cerenkov-idler configuration 광 매개증폭에서의 0° 체렌코프 복사각도 효과
서정식(Zung-Shik Suh) 대한전자공학회 2014 전자공학회논문지 Vol.51 No.1
평판 도파로에서 Cerenkov-idler configuration 형태의 광학적 매개증폭에 대해서 결합모드 이론을 적용하여 결합모드 방정식을 유도하고, 이 방정식의 근사해를 펌핑광의 고갈(depletion)이 없는 경우에 대해서 구한다. 이 근사해로부터 발생되는 idler의 체렌코프 복사각이 0°도에 접근할 때 signal의 이득이 크게 향상될 수 있음을 보여주고 수치적 예를 보인다. Optical parametric amplification has been analyzed for the Cerenkov-idler configuration in planar waveguides. The coupled-mode theory is employed for the analysis. The coupled-mode equations are derived and the approximate analytic solution is obtained for no pump depletion. From the analytic solution, it is shown that the signal power gain can be enhanced as the Cerenkov radiation angle of the idler approaches to zero. The numerical example is also shown for the effect of the Cerenkov radiation angle approaching zero.

Effects of methanol extract of Terminalia chebula on antibacterial activity and the generation of superoxide radical in Bacillus subtilis, as well as on syncytium formation and cytopathic activity in virus-infected baby hamster kidney cells were examined. The extract effectively inhibited syncytium formation in a concentration-dependent manner, and infectious virus production was markedly reduced. However, glycoprotein synthesis was not affected. These results collectively indicate that methanol extract of T. chebula potentially inhibit glycosylation by acting as a suppressor of intracellular glycosylation trafficking.

The condition of transverse phase-matching in Cerenkov-type optical second-harmonic generation in anisotropic slab waveguides is analyzed and at this case second-harmonic power and conversion efficiency are obtained analytically by solving directly the inhomogeneous wave equations which involve the nonlinear polarization.
