Most siblings of childhood cancer patients (SCCP) report not only post-traumatic stress but also daily stresses due to changes in their daily lives. The purpose of this study was to develop a stress scale for SCCP and to examine the validity and reliability of the scale. Based on conceptual analysis, 40 preliminary items were selected. After its content validity was determined by six experts, 37 items were chosen. For the psychometric testing, 125 SCCPs, aged 11-16, were surveyed. Through item analysis and exploratory factor analysis for construct validity, 27 items explained 61.2% of the variance, and they were categorized into six factors. Criterion validity was confirmed by examining the overall correlation with standard instruments according to the age group. Reliability was evaluated using Cronbach's alpha (0.91) and test-retest correlation (r = 0.597). This self-administered questionnaire with a 4-point Likert-type scale may be useful in clarifying and measuring stress levels in SCCPs.

Structural superlubricity (SSL), a state of ultralow friction and no wear between two solid surfaces in contact, offers a fundamental solution for reducing friction and wear. Recent studies find that the edge pinning of SSL contact dominates the friction. However, its nature remains mysterious due to the lack of direct characterizations on atomic scale.

Nanoporous metals have unique potentials for energy applications with a high surface area despite the percolating structure. Yet, a highly corrosive environment is required for the synthesis of porous metals with conventional dealloying methods, limiting the large-scale fabrication of porous structures for reactive metals. In this study, we synthesize a highly reactive Mg nanoporous system through a facile organic solution-based approach without any harsh etching.
