Hg을 도핑한 무거운 페르미온 초전도체 $CeRhIn_5$의 압력에 따른 변화
서순범,주솔,박두선,Seo, S.,Ju, S.,Bauer, E.D.,Thompson, J.D.,Park, T. 한국초전도학회 2012 Progress in superconductivity Vol.14 No.1
The heavy-fermion compound $CeRhIn_5$ is a prototypical antiferromagnet where Ce 4f moments align antiferromagnetically below 3.8 K. When doped with Hg, the antiferromagnetic transition $T_N$ initially decreases, becomes flat, and increases again with further increasing Hg concentration. Here we report pressure effects on the electrical resistivity of a 0.45 % Hg-doped $CeRhIn_5$, where $T_N$ is 3.4 K and the magnetic structure is same as that of the undoped compound with Q=(1/2, 1/2, 0.298). With increasing pressure, $T_N$ is suppressed and a superconducting state emerges. The temperature dependence of the electrical resistivity near an optimal pressure shows a power-law behavior that deviates from a $T^2$ dependence, indicating presence of abundant quantum fluctuations near the optimal pressure.

Purpose: This study aimed to explore the relationship among score of theory course, score of practicum course and clinical practice ability by the course, Adult Health Nursing. Methods: A descriptive research was conducted using questionaries. Data were collected from September 25 to October 2, 2019. Participants were 67 nursing students at one university in Seoul on their junior year who have experienced clinical settings. The collected data were analyzed by t-test, ANOVA, Cohen’s Kappa, and Scheffe’s test using SPSS 25.0 version program. Results: Participants were given a quartile number from 1 to 4 respectively according to their scores of theory course those of practicum course. The total mean score of clinical practice ability was 3.61, with a perfect score of 5. The scores of theory course and practicum course showed slight correlation(Cohen’s Kappa=.168). However, significant correlation did not existed among score of theory course, score of practicum course and clinical practice ability. Conclusion: The result showed that score of theory course, score of practicum course and clinical practice ability have no significant correlation. However, its finding suggests the necessity of further research about various approach and new evaluation methods needed in order to improve nursing students’ competency.
