본 연구는 임상간호사의 간호전문직관과 임상의사결정능력 간의 관계에서 비판적 사고성향과 핵심간호술 수행자신감의 이중매개효과를 검증하여 임상의사결정능력 향상을 위한 기초자료로 활용하기 위해 실시한 서술적 조사연구이다. 연구대상자는 일 지역의 종합병원 임상간호사 173명이며, 2023년 9월 15일～10월 13일까지 자료수집을 하였다. 자료분석은 SPSS/AMOS 23.0 프로그램을 이용하여 연구변인들 간의 인과적 관계 분석과 부트스트래핑 추정방식으로 매개효과를 검증하였으며, t-test, ANOVA, Scheffe’s test, Pearson's correlation coefficient, hierarchical regression을 실시하였다. 연구결과, 첫째, 임 상간호사의 간호전문직관, 임상의사결정능력, 비판적 사고성향과 핵심간호술 수행자신감 간의 인과모형의 적합성은 타당하게 성립하였다. 둘째, 간호전문직관에서 임상의사결정능력에 대한 영향관계에서 비판적 사 고성향은 부분매개효과를 나타냈다. 셋째, 이중매개효과를 검증한 결과, 비판적 사고성향의 간접효과가 비 판적 사고성향과 핵심간호술 수행자신감의 간접효과보다 크게 나타나 이중매개효과보다는 단일매개 효과 가 큰 것으로 나타났다. 따라서 임상간호사들의 높은 간호전문직관의 함양은 임상의사결정능력을 향상시킬 수 있으며, 특히, 비판적 사고성향을 강화시키는 것이 더 효율적임을 검증하였다.

Recently, Free-Form and Irregular Shape high-rise buildings are constructed by IT technology development. Tilted shaped high-rise building which is one of Irregular shape high-rise buildings can cause lateral displacement by gravity load and lateral load due to tilted elevation shape. Therefore, it is necessary to review the behavior and structural aspects of the Tilted shape high-rise building by gravity load. In this paper, the dynamic characteristics of a tilted structure with a dual-core were analyzed with the core location as a design variable, and response behavior, vulnerable members, and vulnerable layers to earthquake loads were analyzed. As a result of the analysis, as the location of the core moved in an tilted direction, the eccentric distance and eccentric load decreased, reducing the axial force of the vertical members. However, the location of the core had little effect on the response.

Two different emitting compounds, 1-[1,1;3,1]Terphenyl-5-yl-6-(10-[1,1;3,1]terphenyl-5-ylanthracen-9-yl)-pyrene (TP-AP-TP) and Poly-phenylene vinylene derivative (PDY 132) were used to white OLED device. By incorporating adjacent blue and yellow emitting layers in a multi-layered structure, highly efficient white emission has been attained. The device was fabricated with a hybrid configuration structure: ITO/PEDOT (40 nm)/PDY-132 (8∼50 nm)/NPB (10 nm)/TP-AP-TP (30 nm)/Alq3 (20 nm)/LiF (1 nm)/Al (200 nm). After fixing TP-AP-TP thickness of 30 nm by evaporation, PDY-132 thickness varied with 8, 15, 35, and 50 nm by spin coating in device. The luminance efficiency of the white devices at 10 mA/cm2 were 2.93 cd/A∼6.55 cd/A. One of white devices showed 6.55 cd/A and white color of (0.290, 0.331).

In this study, shaking table test has been carried out for the dual frame passive control system for seismic performance verification of the proposed system. The proposed system was separated into two independent frameworks that are strength resistant core and frame structure by connecting to the damper. Moreover, the seismic performance improvement of the proposed system has been verified by comparing and analyzing the experimental results of the proposed system with an existing core system. As a result of the shaking table test, acceleration and displacement responses of dual-frame vibration control system are decreased than those of the existing strength resistant type core system. In the case of the core system, while the damage was concentrated on the column of first floor, the damage of the dual system was dispersed in each layer. The damage also was concentrated on the damper, almost no damage occurs to the structural members. It has been emphasized that installed dampers in the proposed dual system reduce the input energy of whole structure by absorbing seismic input energy, which leads overall system damage to be reduced.
