R은 통계 계산과 그래픽을 위해 다양한 기능을 제공하는 언어 및 환경이다. R은 다양한 장점을 제공하지만, 대량의 자료 처리에 대한 고려가 되어 있지 않아서 사용자들이 불편을 겪고 있다. 이 논문에서는, 이러한 대량의 자료 처리 문제를 어떤 방법으로 해결할 수 있으며, 어떠한 추가적인 사항을 생각할 수 있는지 서술하고자 한다.

The web ontology language(OWL) has been used by ontology designers to construct ontology. In order to derive hidden information(concept subsumption, concept satisfiability and realization) of OWL ontology, a number of OWL reasoners have been introduced. But most reasoners simply report these information without process for any arbitrary entailment and unsatisfiable concept derived from a OWL ontologies. In this paper, we propose Minimum Expression Axiom Set(MEXS) detection and storing for debugging unsatisfiable concepts in ontology. In order to detect MEXS, we need to find axiom to cause inconsistency in ontology. Therefore, our work focused on two key aspects: given a inconsistency ontology, identifying the roots of axioms to occur unsatisfiable and derived axioms from among them; and extracting MEXS. Our results can be applicable to all application, which is at the basis of the description logic.

In this study, the picture book reviews shown in Korean periodicals were analyzed to provide the developmental foundation for picture book reviews and expand the professional area of librarians as the producers of book review. Through the literature research and the Delphi Technique the desirable standard of book reviews was suggested, the contents in domestic book review mediums were analyzed for the rightness of describing based on the standard of the book review and henceforward the way of development was suggested. The result from analysis of book review showed that the outstanding book reviews should be more produced based on the desirable standard of book review and the evaluative statements should be developed more than the descriptive statements. Depending on the mediums the contents of the book review were different by the book reviewers' occupations, so the book reviewers should develop their professional knowledges in literature and art. Because the longer book review made the outstanding book review with the rightness of the desirable standard of book review, the certain quantity of book review should be needed and the role of librarians as the book reviewers should be further extended.

This study aimed to identify factors that influence depression in juvenile offenders. A cross-sectional study design was used. The participants were 275 juvenile offenders from D city. The collected data were analyzed using t-test, ANOVA, Pearson's correlation coefficients, and multiple regression with the SPSS/WIN 20.0 program. Of the participants, 32.4% and 52.0% were in the clinical group for ADHD and depression, respectively. ADHD symptoms and self-esteem were significantly correlated with depression. The final model showed that depression among juvenile offenders was significantly influenced by perceived health status, ADHD symptoms, and self-esteem. These variables accounted for 37% of the variance of depression.

This study is a descriptive research study to understand the relationship between sedation, delirium, and fall of people with mental illness taking psychiatric drugs. From March10, 2019 to November 10, 2019, four psychiatric nurses were evaluated on 149 people with mental illness in two psychiatric hospitals located in D city. The collected data were analyzed using descriptive statistics, t-test, ANOVA, and Pearson's correlation coefficient using SPSS 22.0. Sedation and delirium(r=.587, p=<.001), sedation and fall(r=.273, p=.001), delirium and fall(r=.390, p=<.001)were all significant positive correlation. This study identified the degree of sedation, fall, and delirium of patients taking psychiatric drugs and confirmed the relationship between sedation, fall, and delirium of people with mental illness. It is thought that it will be able to provide basic data to prevent falls and delirium that may occur when taking psychiatric drugs and to prepare a nursing intervention strategy.

This study was conducted to identify the relationships among critical thinking disposition, professional self-concept and satisfaction of clinical practice in nursing students. The participants were 212 nursing students in Gyeonggy Province. Data was collected from June 1 to 12, 2015 using self-report questionnaires and analyzed through descriptive statistics, t-test, ANOVA and Pearson correlation coefficient with SPSS/win. 21.0. Critical thinking disposition, professional self-concept and satisfaction of clinical practice averaged 3.61(out of 5), 2.94(4), and 3.54(5), respectively. Significant positive correlations between critical thinking disposition and professional self-concept, satisfaction of clinical practice and professional self-concept were found, Therefore it is necessary to strengthen critical thinking and professional self-concept and improve satisfaction of clinical practice through effective educational program.

The purpose of this study was to identify the relationship of career-related stress, commitment to a career choice and career decision self-efficacy of college students. The participants were 293 college students in P city. Data were collected by using self-report questionnaires from May 6 to 29, 2015. Data were analyzed with descriptive statistics, t-test, ANOVA, Pearson,s correlation coefficient and Hierarchical regression analysis by SPSS/WIN 23.0 program. The career-related stress was negatively correlated with commitment to a career choice (r=-.731, p<.001) and career decision self-efficacy(r=-.449, p<.001). The influencing factors of career-related stress were grade(${\beta}$=.99, p<.017) and commitment to a career choice(${\beta}$=-.707, p<.001). This study concludes that it is necessary to develop education program to improve commitment to a career choice and career decision self-efficacy.

In this paper, we propose a new feature matching algorithm which is robust to the viewpoint change by using the FAST(Features from Accelerated Segment Test) feature detector and the SIFT(Scale Invariant Feature Transform) feature descriptor. The original FAST algorithm unnecessarily results in many feature points along the edges in the image. To solve this problem, we apply the principal curvatures for refining it. We use the SIFT descriptor to describe the extracted feature points and calculate the homography matrix through the RANSAC(RANdom SAmple Consensus) with the matching pairs obtained from the two different viewpoint images. To make feature matching robust to the viewpoint change, we classify the matching pairs by calculating the Euclidean distance between the transformed coordinates by the homography transformation with feature points in the reference image and the coordinates of the feature points in the different viewpoint image. Through the experimental results, it is shown that the proposed algorithm has better performance than the conventional feature matching algorithms even though it has much less computational load.

In conventional thermodynamics, energy is regarded as a physical quantity transferring from one system to another, but in present study, the real energy is regarded as a physical quantity coming out from one interaction and absorbing into another interaction between two systems. To reconstruct thermodynamics with such a point of view, available work is distinguished from half work in conventional work concepts, and a special space named reversible world is proposed in which every process is reversible and the only measurable quantity is available work and just the equality between the intensities of two systems can be verified. As results, thermodynamic laws are arranged into two principles in the reversible world-conservations of energy elements and conservation of available energy. It means the exsistences of state properties corresponding to transferring energy elements and the available work. The former are extensive properties and the later is named potential work which is a property of the composite system and a kind of mathematical distance. The conventional available energy (exergy) and internal energy can be explained as the special cases of potential work, and the conventional first law of thermodynamics can be derived from the principle of the conservation of available energy. With these new concepts, the description of thermodynamic processes is more comprehensive. The second law of thermodynamics is no longer needed in the reversible world.
