서로 다른 두께를 가진 철/망간산화물 다층박막들을 펄스 레이저 증착기법으로 성장시켰다. 소각 입사 X-선 반사율 측정결과 뚜렷한 다층박막 Bragg peak들이 보임으로써 시료가 좋은 층상구조를 가지고 있음을 확인할 수 있었고, 이를 분석하여 정량적인 구조변수를 얻었다. 또한 MnO의 (111)면에 해당하는 X-선 회절 peak를 통해 망간산화물은 대부분 MnO 형태로 존재함을 알았다. 이러한 Mn+²의 자기적 특성을 알아보기 위해 XMCD를 측정하였으며, 계면근처에서 MnO의 자기모멘트는 Fe과는 반대방향으로 정렬하고 있음이 확인되었다. Fe/MnO multilayers with different bilayer thicknesses were grown by pulsed laser deposition method. Grazing incidence X-ray reflectivity results showed obvious multilayer Bragg peaks implying highly layered samples and, through their analysis, some structural parameters were quantitatively estimated. From the X-ray diffraction peak corresponding to MnO(111), Mn-oxide turned out to be dominantly MnO. To characterize the magnetic properties of Mn+², XMCD were carried out. Magnetic moments of MnO near interfaces were ordered in the opposite direction to those of Fe.

Purpose: The purpose of this study was to investigate clinical practice stress, academic self-efficacy, and career identity among undergraduate students in nursing practicum. Method: This study was a descriptive correlational design using the survey method. The study included 267 undergraduate students attending to 5 college in Seoul. The data was gathered from August 2014 to October 2014 and the data were analyzed using IBM SPSS statistics version 22.0 Program with descriptive statistics, t-test, analysis of variance with Scheffe test, and Pearson’s correlation coefficient. Results: Situational characteristics of Clinical Practice Stress(CPP) was significantly different with regards to task difficulties and efficacy self-confidence of academic self-efficacy(ASE) (r= .179, p= .003; r= .166, p= .006). Statistically significant positive relationship was founded between Personal characteristics of CPP and self-confidence of ASE (r= .239, p< .01). External regulators of CPP was significantly different according to self-confidence and task difficulties (r= .175, p= .003; r= .132, p= .028). The self-confidence and efficacy for self-confidence of ASE were a significantly correlated with Career Identity; The Career identity also was a significantly correlated with all sub-categories of CSS scale(r= -0.208, p< 0.01; r= -0.369, p< 0.01; r= -0.153, p< .011) Conclusion: This study showed positive statistical relationships associated with clinical practice stress, academic self-efficacy, and career identity as a preliminary evidence-based study for guiding education in nursing curriculum. Further research should be need for students’ future as a professional nurse.
