Purpose : The purpose of this study was to investigate the effect of the perceived nursing work environment (NWE) on person-centered critical care nursing (PCCN) practices among nurses in intensive care units (ICUs). Methods : A cross-sectional research design was adopted for this study; participants were 126 ICU nurses working in five hospitals in B city. From December 2018 to February 2019, a survey questionnaire on NWE and PCCN were conducted. The collected data were analyzed with a multiple hierarchical regression analysis. Results : The mean score for NWE was $2.98{\pm}0.39$. Among the factors, basic work system was the highest ($3.39{\pm}0.41$), followed by leadership of the head nurse ($3.31{\pm}0.55$), interpersonal relationships ($2.77{\pm}0.62$), and institutional support ($2.58{\pm}0.52$). The mean score for PCCN was $3.52{\pm}0.46$. Among the factors, comfort was the highest ($3.77{\pm}0.62$), followed by respect ($3.55{\pm}0.56$), compassion ($3.43{\pm}0.60$), and individuality ($3.38{\pm}0.56$). The interpersonal relationship (${\beta}=.31$, p=.001) and the number of patients per shift (${\beta}=-.23$, p=.005) had a significant effect on PCCN, accounting for 25.9% of the total variance. Conclusion : These results suggest that it is necessary to enhance the relationship-oriented culture and reduce the workload of nurses in order to improve the quality of nursing care in ICUs.

This paper dealt with investigating the number of minimal spanning ladders originated from ladder game and their properties as well as the related computational thinking aspects. The author modified the filtering techniques to enhance Mathematica project where a new type of graph was generated based on the algorithm using a generator of firstly found minimal spanning graph by repeatedly applying independent ladder operator to a subsequence of ladder sequence. The newly produced YC graphs had recursive and hierarchical graph structures and showed the properties of edge-symmetric. As the computational complexity increased the author divided the whole search space into the each floor of the newly generated minimal spanning graphs for the (5, 10) YC graph and the higher (6, 15) YC graph. It turned out that the computational thinking capabilities such as data visualization, abstraction, and parallel computing with Mathematica contributed to enumerating the new YC graphs in order to investigate their structures and properties.

In this study, we have look through the national progress of computer science education in South Korea and analyzed the main subjects and contents of each period. We suggests the ways to evolve the current computer science education in terms of class hours for computer science education, hierarchical instructions, and the limitation of current national curriculum. In South Korea, it has been leaded the computer science education in the world since the it was promoted in earnest since 1995. Based on the recently revised national curriculum, South Korean government are taking efforts to nurture a leader through computer science education in terms of the students' future skills. However, it should be promoted to strengthen the ability of not only problem-solving ability through programming education, but also balanced computing and digital literacy through enhancing the ICT skills. In order to improve the curriculum of computer science education in elementary school of South Korea, a sufficient class hours of computer science education should be secured first.

In this paper, we introduce a technique to detect the video forgery by using the regularity that occurs in the video compression process. The proposed method uses the hierarchical regularity lost by the video double compression and the frame deletion. In order to extract such irregularities, the depth information of CU and TU, which are basic units of HEVC, is used. For improving performance, we make a depth map of CU and TU using local information, and then create input data by grouping them in GoP units. We made a decision whether or not the video is double-compressed and forged by using a general three-dimensional convolutional neural network. Experimental results show that it is more effective to detect whether or not the video is forged compared with the results using the existing machine learning algorithm.

Purpose: This study investigated the effects of nursing organizational culture and self-leadership on job satisfaction for nurses working in the comprehensive nursing care service ward in public hospitals. Methods: The participants were 138 nurses working in Gyeonggi-do medical center. The collected data were analyzed using descriptive statistics, t-test, ANOVA, Pearson's correlation coefficients, and regression analysis with SPSS/WIN 23.0. Results: Factors affecting job satisfaction were innovation-oriented culture (${\beta}=.29$, p<.001), want to work in this department (${\beta}=-.25$, p<.001), the cognitive strategy of self-leadership (${\beta}=.23$, p=.002), hierarchical-oriented culture (${\beta}=-.21$, p=.002), and marital status (${\beta}=.18$, p=.005). These factors accounted for 42.0% of the variability in job satisfaction. Conclusion: In order to improve the job satisfaction of nurses in the comprehensive nursing care service ward in public hospitals, institutional-level efforts should be made to encourage an innovation-oriented culture and avoid a hierarchy-oriented culture. In addition, education and program development are needed to improve the cognitive strategy of self-leadership.
