  • Effect of Pd addition on crystal structures of two nickel silicides, NiSi and $NiSi_2$, is investigated by using an ab initio calculation. A Pd atom substitutes a Ni and Si site, respectively, to evaluate the preferable site between them. Pd prefers Ni site to Si site in NiSi, while it prefers Si site to Ni site in $NiSi_2$. The calculated total energy also indicates that the Pd substitution to Si site stabilizes the $NiSi_2$ structure. This calculated data matches well with the experimental data obtained from Atom probe.

  • The professional duties of librarians and other information workers involve a generalized body of both theoretical and practical knowledge (the so-called, 'common core') which is a n.0, pplicable worldwide without regard to national boundaries, levels of economic and technical development or cultural context. The current study is an attempt to validate and su n.0, pport this common core concept through a detailed examination of its important role in the sound development of library and information science both as a learned subject and as a profession. Following an initial overview of generally agreed upon core areas in the education and training of librarians and information specialists, with particular attention to the manifold social changes rapidly being effected by computers and communication technology, the focus shifts to the proliferation of academic homes for information science education and its implications for core areas in information science. Of note here is the relationship between information science as a broadly accepted social science discipline and the evolving core curriculum in library schools. To this regard the fact that the popularization of computers and communication technology is increasingly blurring the once-sharp differences between traditional librarians and information specialists naturally favors common core concept. Major figures in library and information science education such as Shera, Saracevic and Foskette su n.0, pport this concept and have already identified its theoretical infrastructure. Finally, UNESCO and IFLA are also stressing the common core cure curriculum for library and information science both as guidelines for the Third World and as a means to achieve universally accepted academic standards. In conclusion, the search for a comprehensive common core curriculum in library and information science education is still in the elementary stages. The task of identifying the components of this common core is among the most crucial responsibilities facing today's educators and professionals for the successful elaboration of a common core would enable us to attain three highly desirable professional goals: 1) To determine the basic concepts and principles of library and information science. 2) To serve as the base for further professional education and specialized research. 3) To offer enhanced o n.0, pportunities for integrated library and information science education programs by providing a genuine two-way communication channel between the library and information science professions.

  • Due to the development of information communication technology, educational environment has undergone much change and various types of teaching and learning methods based on information communication technology has been suggested. Recently, remote education using the internet are also spreading. However, in current classrooms, students are asked to do an teacher-centered assignment, which they are required to collect and report some information using the internet. This method does not help students use the advantages of learning using the internet, which stimulate students-students interaction and teacher-students interaction.Thus, this study focused on the problem-based learning system based on video communication technology. The researcher designed the problem-based learning system based on video communication technology and applied the system to classes at elementary school. The results were analyzed in terms of students-students interaction and teacher-students interaction in the internet. This research found that the problem-based learning system stimulates teacher and students communication and has positive effects on students' attitude and interest in learning. This research proposes that the traditional teacher-centered teaching method can be supplemented with cyber space learning, which has the merit of problem-based learning model.

  • The importance of software in the engineering field is increasing day by day, so the utilization and understanding of the simulation software in the engineering design stage has become the core competence of the engineer. This study presents a new software education method for multiple systems in the field of mechanical engineering using a workflow execution environment as a sub-module of a computational platform (called EDISON platform) that can incorporate in-house software tools developed by many simulation tool developers. It can execute not only individual software tools such as fluid flow, structure, optimal design, but also conduct connective executions of multiple software tools. Based on this simulation environment, a methodology was proposed that can be applied to convergence types of engineering educations. By properly using this methodology, it is expected that beginning engineers could encourage their specialties understanding the big pictures of the analysis processes.

  • In this study, we applied the long short-term memory (LSTM) model to classify the cryptocurrency price time series. We collected historic cryptocurrency price time series data and preprocessed them in order to make them clean for use as train and target data. After such preprocessing, the price time series data were systematically encoded into the three-dimensional price tensor representing the past price changes of cryptocurrencies. We also presented our LSTM model structure as well as how to use such price tensor as input data of the LSTM model. In particular, a grid search-based k-fold cross-validation technique was applied to find the most suitable LSTM model parameters. Lastly, through the comparison of the f1-score values, our study showed that the LSTM model outperforms the gradient boosting model, a general machine learning model known to have relatively good prediction performance, for the time series classification of the cryptocurrency price trend. With the LSTM model, we got a performance improvement of about 7% compared to using the GB model.

  • Trajectory prediction is an essential element for driving autonomous vehicles, and various trajectory prediction models have emerged with the development of deep learning technology. Convolutional neural network (CNN) is the most commonly used neural network architecture for extracting the features of visual images, and the latest models exhibit high performances. This study was conducted to identify an efficient CNN backbone model among the components of deep learning models for trajectory prediction. We changed the existing CNN backbone network of multiple-trajectory prediction models used as feature extractors to various state-of-the-art CNN models. The experiment was conducted using nuScenes, which is a dataset used for the development of autonomous vehicles. The results of each model were compared using frequently used evaluation metrics for trajectory prediction. Analyzing the impact of the backbone can improve the performance of the trajectory prediction task. Investigating the influence of the backbone on multiple deep learning models can be a future challenge.

  • In this paper, the abdominal-deformation measurement scheme is conducted on a shape-flexible mannequin using the DIC technique in a stereo-vision system. Firstly, during the integer-pixel displacement search, a novel fractal dimension based on an adaptive-ellipse subset area is developed to track an integer pixel between the reference and deformed images. Secondly, at the subpixel registration, a new mutual-learning adaptive particle swarm optimization (MLADPSO) algorithm is employed to locate the subpixel precisely. Dynamic adjustments of the particle flight velocities that are according to the deformation extent of each interest point are utilized for enhancing the accuracy of the subpixel registration. A test is performed on the abdominal-deformation measurement of the shape-flexible mannequin. The experiment results indicate that under the guarantee of its measurement accuracy without the cause of any loss, the time-consumption of the proposed scheme is significantly more efficient than that of the conventional method, particularly in the case of a large number of interest points.
