  • The purpose of this study was to analyze the teachers' stages of concern and levels of use on STEAM of the 2009 elementary science curriculum and to support effective application according to the teachers' stages and levels. Therefore this study was conducted by the Concerns-Based Adoption Model (CBAM). The total number of 113 teachers participated in this study. The results of the study were as follows: First, most teachers were in the stage of awareness. Second, the results of the chi-square test showed that the stages were significantly different according to their positions, training experiences and final degrees (p<.05). Third, about half of teachers were in the level of orientation and preparation. The others were in the level of routine, integration and renewal. Fourth, the results of the chi-square test showed that the levels were significantly different with the categories of their gender, position, age, career in education, workplace and training experience (p<.05). Fifth, the correlation coefficient between stages of concern and levels of use (r=.59) was relatively high (p<.05). Based on these results, we suggested that the support of application should be provided according to the teachers' stages and levels.

  • This study discusses the meanings of nationality in information behaviour. In this study nationality was represented by citizenship and group personality(here, dependency) Surveys were conducted for data collection, and a questionnaire were completed by 331 participants(158 Korean students and 183 Japanese students). Simple frequency tests and chi-square tests were conducted to examine the proposed relation between citizenship and information behavior, that between dependency and information behavior. Also conducted was two-way ANOVA test to examine the relative significance of two independent variables(citizenship and dependency) in information behavior. The results of chi-square tests showed that both variables have statistically significant relationship with information behavior although the relationship was partially significant. And the results of ANOVA test showed that between the two variables, citizenship was more significant than dependency.

  • The performance of deep learning-based malware detection and classification models depends largely on how to construct a feature set to be applied to training. In this paper, we propose an approach to select the optimal feature set to maximize detection performance for CNN-based Android malware detection. The features to be included in the feature set were selected through the Chi-Square test algorithm, which is widely used for feature selection in machine learning and deep learning. To validate the proposed approach, the CNN model was trained using 36 characteristics selected for the CICANDMAL2017 dataset and then the malware detection performance was measured. As a result, 99.99% of Accuracy was achieved in binary classification and 98.55% in multiclass classification.

  • Infrastructure capacities are essential elements and one of the sustainable lines to drive economic growth. Infrastructure development, both physical and social, is vital to sector-wise economic development. However, there is limited evidence of how infrastructure development in certain sectors benefits the economy as a whole. This study explains the relationships between infrastructure and economic growth in selected middle-income Asian countries, highlighting the essential criteria to benefit from both physical and social infrastructure, as well as sectoral (agriculture, industry, and services) economic output. The research uses the data from 1990 to 2020 for empirical estimations. The study used Levin, Lin, & Chu test, ADF- Fischer chi- Square, and PP- Fischer Chi-Square to test unit root and to observe the stationary nature of the panel. Padroni and Kao cointegration is applied to check the cointegration among different panes. A Fully Modified OLS was employed for checking the association between physical and social infrastructure and economic growth. Results show that physical and social infrastructure negatively impact sectoral output in Asia's middle-income countries. Apart from infrastructure the per capita GDP growth, tax to GDP ratio, and population growth shows a simultaneous relation between infrastructure and sectoral economic growth.

  • A conceptual model represents an understanding of a system that is going to be developed, which in this research, a driving simulation software to study driver behavior at signalised intersections. Therefore, video observation was conducted to study driver compliance behaviour within the dilemma zone at signalised intersection, with regards to driver's distance from the stop line during yellow light interval. The video was analysed using Thematic Analysis and the data extracted from it was analysed using Chi-Square Independent Test. The Thematic Analysis revealed two major themes which were traffic situation and driver compliance behaviour. Traffic situation is defined as traffic surrounding the driver, such as no car in front and behind, car in front, and car behind. Meanwhile, the Chi-Square Test result indicates that within the dilemma zone, there was a significant relationship between driver compliance behaviour and driver's distance from the stop line during yellow light interval. The closer the drivers were to the stop line, the more likely they were going to comply. In contrast, drivers showed higher non-compliant behavior when further away from stop line. This finding could help in the development of conceptual model of driving simulation with purpose in studying driver behavior.
