This paper describes a fingerprint classification on the basis of feature points(whorl, core) and feature vector and uses a syntactic approach to identify the shape of flow line around the core. Fingerprint image is divided into 8 by 8 subregions and fingerprint region is separated from background. For each subregion of fingerprint region, the dominant ridge direction is obtained to use the slit window quantized in 8 direction and relaxation is performed to correct ridge direction code. Feature points(whorl, core, delta) are found from the ridge direction code. First classification procedure divides the types of fingerprint into 4 class based on whorl and cores. The shape of flow line around the core is obtained by tracing for the fingerprint which has one core or two core and is represented as string. If the string is acceptable by LR(1) parser, feature vector is obtained from feature points(whorl, core, delta) and the shape of flow line around the core. Feature vector is used hierarchically and linearly to classify fingerprint again. The experiment resulted in 97.3 percentages of sucessful classification for 71 fingerprint impressions.

Purpose: This study aimed to investigate basic data on preceptor's core competencies required for junior 119 paramedics to improve the quality of emergency care in the prehospital field. Methods: From February 23 to March 10, 2021, data were collected through structured mobile questionnaires from 163 paramedics working in Sejong, Daejeon, and Chung Nam fire stations. The data were analyzed using SPSS version 25.0. Results: The average score of core competencies for junior 119 paramedics accounted for the importance of core competency (3.92 points), level of competence (3.43 points), educational needs (3.65 points). Among them, the importance of a role model accounted for 4.02 points, the highest among the sub-areas. Additionally, there was a significant correlation (r=.686), which was the highest, between the importance and educational needs of core competency; therefore, higher the importance of core competency, higher are the educational needs. Conclusion: Preceptor's core competencies concern three domains: role model, socialization facilitation, and instructional design. It would be more effective for those with higher professionalism and professional self-development needs to be trained as a prehospital preceptor.

Different types of fingerprint detection algorithms that are based on extraction of minutiae points are prevalent in recent literature. In this paper, we propose a new algorithm to locate the virtual core point/centroid of an image. The Euclidean distance between the virtual core point and the minutiae points is taken as a random variable. The mean, variance, skewness, and kurtosis of the random variable are taken as the statistical parameters of the image to observe the similarities or dissimilarities among fingerprints from the same or different persons. Finally, we verified our observations with a moment parameter-based analysis of some previous works.

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.

Although each de Morgan algebra has not always fixed points(centers), it has always fixed cores, the natural extention of fixed points. Fixed cores, of they do not degenerate to fixed points, are Boolean algebras, It is also shown the necessary and sufficient condition a algebra to be a Kleene algebra(fuzzy algebra) is that it has just one fixed core.

This study was attempted to provide fundamental data in a disaster response education program by comparing the differences between students of the paramedic and nursing in ego-resilience, disaster-experience and core competencies of disaster response. The data is collected from March 2 to April 2, 2019, on a total of 358 students (196 paramedic students and 162 nursing students) based in Jeolla Province. The structured questionnaire were used as research tools and the collected data were analyzed by using the SPSS program as frequency, percentage, t-test, ANOVA and Pearson's correlation coefficient. The average score of total ego-resilience among the subjects was 86.97 out of 125 points. The number of paramedic students who experienced or witnessed the disaster situation in person was 11.2%, and the number of nursing students was 11.7%. The core competence of disaster response was 3.21% in paramedic students and 3.16% in nursing students. The ego-resilience of the paramedic and nursing students according to their general characteristics is statistically significant differences (t=2.797, p<.005) and the paramedic students has an average score of 3.52 points, which is higher than the nursing students (3.42 points). General characteristics and experience in disasters are statistically significant differences (t=2.797, p<.005), paramedic students had more disaster experiences (3.11 points) than nursing students (2.67 points). It indicated the static correlation relationship between ego-resilience, disaster experience and core competences of disaster response (p<.000). Through this study, the paramedic students were found to be more ego-resilience, more disaster experience and more critical capacity for disaster treatment than nursing students.

The elastic properties of core affect mechanical properties and deformation behaviours of the lightweight sandwich panel. The objective of the present paper is to estimate experimentally Young's and shear moduli of a core in internally structured boned (ISB) panel with woven metal as inner structures using the deflection theory of sandwich beam considered core stiffness. Three points bending experiments were performed to obtain force-deflection curves of the designed ISB panel in each material direction. The elastic and shear moduli of the core in each material direction were estimated from slopes and intercepts of relationships between compliance per the span length and square of the span length, respectively. The results of the estimation showed that the fabric technology of the woven metal affects the variation of the elastic properties in the core. Through the comparison of shear moduli and force-deflection curves of the proposed method and those without considering the core stiffness, it was shown that the core stiffness should be considered to estimate properly the Young's and shear moduli of ISB panels. Finally, the contribution ratio of bending and shear deflections of ISB panels to the total deflection was quantitatively examined.

Purpose: This study was to investigate the effect of nurses' core competencies and cognition of job competency of senior nurses on work performance. Methods: Three hundred two nurses participated in the study. The collected data were analyzed with SPSS/WIN 20.0. Frequency, t-test, ANOVA and stepwise multiple regression were utilized. Results: The level of nurses' core competencies was 3.65 (${\pm}.40$) points, cognition of job competency of senior nurses was 4.02 (${\pm}.60$) points, and work performance was 4.04 (${\pm}.55$) points. In accordance with the participant's general characteristics, work performance was found to be significant in their age, marital status, educational level, total clinical experience, length of time on the present ward, and their income. Cognition of job competency of senior nurses was found to be the most effective factor in work performance, followed by core competencies and total clinical experience, and these factors accounted for 63.4%. Conclusion: The study suggested that work performance was highly affected by the nurses' core competencies and cognition of job competency of senior nurses. Therefore, effective education programs are required to provide an appropriate experience to both entry-level and experienced nurses, as well as to help in enhancing nurses' and senior nurses competency at the same time.

The measure to encourage participation of ESCO business for companies with core technology may vary on the conditions of preference policy considerations. Accordingly, the three measures are can be suggested, evaluation points for incentives, loan allocated to a separate, and participation with consortium. This study recommends that the evaluation points for incentives is preferred in the ways. If the assumption that the allocation of large amounts of money, the amount of the loan allocated to a separate may be considered as suboptimal.
