In this study, electrically conductive materials composed of carboxylated polypyrrole (PPy(COOH)) andnontoxic oligosaccharide molecules (cyclodextrin, CD) were prepared and incorporated intobiocompatible hydrogels for use as versatile sensors. The major component, carboxylated polypyrrolenanotubes (PPy(COOH) NTs) were fabricated using microemulsion polymerization and a critical sensingmedium CD molecule was introduced via a simple surface engineering method. The resulting PPy(COOH)-CD NT hybrid complexes were incorporated into a hydrogel matrix for biocompatibleapplications. Consequently, a convenient sensor geometry was constructed by mounting the hydrogelon a gold micropattern for the detection of toxic substances. The feasibility of the produced sensor systemwas demonstrated, and the sensor performance was measured extensively using electrical measure-ments. It was found that the sensor could detect a model compound (methyl paraben, MPRB) atconcentration as low as 1 nM. This study provides useful information for future research activities inrelevantfields.

Aim(s): There is a lack of research that has produced results on the relationship between nursing college students' nursing process performance, critical thinking disposition, and nursing information literacy competency. This study seeks to understand the impact of nursing college students' critical thinking disposition and nursing information literacy competency on nursing process performance. Method(s): The subjects of study are 180 students from the Department of Nursing at K University in E providence. Data collection took place from 17 August to 2 September 2020. The research tools used critical thinking disposition, NILC-N (Nursing Information Literacy Competency) tools, and nursing process performance tools. The collected data analysis used the SPSS/WIN 25.0 program, using technical statistics and Independent t-test, ANOVA, Pearson’s correlation coefficient method. Result(s): Critical thinking disposition is whether or not nursing courses are completed (121.79±16.28 vs 119.31±21.52, t=.842, p=.028) showed a difference depending on. Nursing information literacy competency differed between the first and second groups(83.93±16.15) and the third and fourth grade groups(99.04±12.18). Nursing information literacy competency differed depending on whether or not clinical practice was experienced(99.12±12.09 vs 83.65±16.09, t=7.177, p=.047) and Completion of nursing informatics course (65.78±9.57 vs 49.48±16.38, t=5.501, p=.015) showed differences. The study subjects’ nursing process performance showed a positive correlation between critical thinking disposition(r=.413, p<.001) and nursing information literacy competency(r=.769, p<.001). Conclusion(s): It was confirmed that the impact on nursing college students’ ability to nursing process performance was critical thinking disposition and nursing information literacy competency. In order to improve nursing college students' nursing process performance, it is necessary to develop educational programs that can foster nursing information literacy competency and critical thinking levels.
