This study examined the effects of reeducation of core basic nursing skills on competence, confidence and anxiety in nursing students. We collected the data from 176 2nd grade nursing students. Reeducation of core basic nursing skills was conducted from December 20th to 23rd, 2016. Data were analyzed by SPSS 21.0 program. As the result of reeducation, significant improvement was found in competence(t=-11.57, p<.001), confidence(t=-10.21, p<.001) and considerable decrease was recognized in anxiety(t=-4.76, p<.001). In conclusion, reeducation of core basic nursing skills can help students to improve their overall competence and confidence, and also to reduce their anxieties as they start their first clinical practice. Therefore we suggest that more systematic and continual reeducation of core basic nursing skills should be applied to each grade of nursing students who are facing their clinical practice in hospital

Given a prime number p and a natural number m not divisible by p, we propose the problem of finding the smallest number r₀ such that for r ≥ r₀, every group G of order p^rm has a non-trivial normal p-subgroup. We prove that we can explicitly calculate the number r₀ in the case where every group of order p^rm is solvable for all r, and we obtain the value of r₀ for a case where m is a product of two primes.

Purpose: The purpose of the study was to investigate the core competency and educational needs of paramedic students in disaster management. Methods: A self-reported questionnaire was completed by 207 paramedic students between June 1 and October 29, 2017. The study instrument included disaster preparedness (15 items), disaster management core competency (26 items), disaster education needs (26 items). Data were analyzed using t-test, ANOVA, and Duncan's multiple range test using IBM SPSS 24.0. Results: The students reported that only 13% had experienced or witnessed disasters; however, 95.2% would be willing to help in the event of a disaster. Their disaster preparedness was 1.84 points on a 3-point scale. We did see differences in disaster preparedness by background: hospital practice (F=5.352, p=.001); fire-fighting practice (F=8.994, p=.000). The students had a core competency of disaster management at 3.25 points on a 5-point scale with differences depending on major satisfaction (F=3.760, p=.006). The level of student demands for disaster education was 4.29 points. Conclusion: If variety of educational environments are provided for disaster-related learning and training, the core competency of disaster management for paramedic students will improve. The students will be available as disaster management experts in various fields, even after graduation.

Purpose: The purpose of this study was to evaluate the effects of Metaverse-based core nursing skill contents (CNSC) developed for undergraduate nursing students. Methods: A nonequivalent control group was sampled with a non-synchronized design. Seventy-two participants (experimental group 34, control group 38) were recruited from May to June 2022 in Gwangju metropolitan city. The CNSC consisted of scenarios of vital sign measurements, and subcutaneous injections (including blood sugar tests). The data were analyzed using SPSS version 25 for Windows. Results: At the completion of the CNSC, statistically differences were found between groups in knowledge of core nursing skills (t=6.20, p<.001), confidence in core nursing skills performance (t=5.71, p<.001), and clinical competency (t=3.32, p=.001). Conclusion: These results indicate that the CNSC developed for undergraduate nursing students is effective in improving knowledge of core nursing skills, confidence in core nursing skills performance, and clinical competency for nursing students.

Hydrophobic core variant of ubiquitin appeared to have partially folded structure at pH around 2. The intrinsic tryptophan fluorescence emission maximum of this ubiquitin variant at pH 2 showed slight blue shift compare to that of unfolded state, suggesting that some residual tertiary structures remain in this solvent condition. At the same solvent condition, this ubiquitin variant binds with hydrophobic dye, 8-anilinonaphthalene-1-sulfonic acid(AMS), which is known to bind to exposed hydrophobic surface. Furthermore, far-UV circular dichroic spectrum of this ubiquitin variant in the diminished pH was remarkably different from the far-UV CD spectrum of the native state or unfolded state. Based on the molar ellipticity at 220 nm, this ubiquitin variant at pH 2 appeared to have significant amount of secondary structures. All these observations suggest that this ubiquitin variant in the diminished solvent pH has loosely folded hydrophobic core with some secondary structures, which are key features of molten globule conformation. Since molten globule has long been considered as a protein folding intermediate, it is considered that this hydrophobic core variant ubiquitin will serve as a valuable model to study protein folding process.

This study investigates the main growth mechanism of InP during InP/ZnS reaction of quantum dots (QDs). The size of the InP core, considering a synthesis time of 1-30 min, increased from the initial 2.56 nm to 3.97 nm. As a result of applying the proposed particle growth model, the migration mechanism, with time index 7, was found to be the main reaction. In addition, after the removal of unreacted In and P precursors from bath, further InP growth (of up to 4.19 nm (5%)), was observed when ZnS was added. The full width at half maximum (FWHM) of the synthesized InP/ZnS quantum dots was found to be relatively uniform, measuring about 59 nm. However, kinetic growth mechanism provides limited information for InP / ZnS core shell QDs, because the surface state of InP changes with reaction time. Further study is necessary, in order to clearly determine the kinetic growth mechanism of InP / ZnS core shell QDs.

In this study, we investigate the optical properties of InP/ZnS core/shell quantum dots (QDs) by controlling the synthesis temperature of InP. The size of InP determined by the empirical formula tends to increase with temperature: the size of InP synthesized at $140^{\circ}C$ and $220^{\circ}C$ is 2.46 nm and 4.52 nm, respectively. However, the photoluminescence (PL) spectrum of InP is not observed because of the formation of defects on the InP surface. The growth of InP is observed during the deposition of the shell (ZnS) on the synthesized InP, which is ended up with green-red PL spectrum. We can adjust the PL spectrum and absorption spectrum of InP/ZnS by simply adjusting the core temperature. Thus, we conclude that there exists an optimum shell thickness for the QDs according to the size.

Purpose : The purpose of this study was to develop a core competency evaluation tool of the preceptors training new graduate nurses and to determine the validity of the developed instrument. Method : This study was conducted in 2 phases. In phase I, preceptor's core competency list was developed through literature review, focus group interview, and review by nursing directors and nurse managers. In phase II, 60 preceptors were evaluated with the developed instrument and categorized into excellent, good & poor core competency groups. For validation of the instrument, new graduates' clinical performance improvement and satisfaction with preceptor were compared between excellent and poor group. Result : The data were analyzed by SPSS P.C and the results were as follows. 1) Preceptor's core competencies were classified into three domains; Role model(10 items), Socialization facilitator(8 items), and Educator(16 items), and each item had four point system of "strongly agree" to "strongly disagree". Cronbach'${\alpha}$ of the instrument was.9416. 2) Comparison of clinical performance improvement and satisfaction with preceptor of the new graduates trained by excellent and poor preceptors revealed that new graduates' clinical performance improvement(p=.015) and satisfaction with the preceptor(p=.005) were significantly higher in the excellent core competency preceptor group than the poor core competency preceptor group. Conclusion : The validity of the preceptor's core competency evaluation tool developed in this study was confirmed. Therefore, this tool can be effectively utilized for education and evaluation of new graduates' preceptors in clinical settings.
