The purpose of this study is to discuss the current status and limitations of convergence education in universities and to explore new possibilities of engineering convergence education by analyzing characteristics and cases of self - design semesters as convergence education. As a result of this study, it was found that the education for fostering convergence ability is insufficient for the viewpoint of education. The types of convergence education could be classified into three categories. However, the concept and paradigm of convergence education has not been established precisely because it is made in a 'top-down' manner by the government. In addition, there was a limit of the lack of a foundation to operate the convergence education. However, A university's self-design semester, it shows the possibility of cultivating the overall convergence ability by giving autonomy and subjectivity to learners and through the acquisition of contextual knowledge and the ability of collaboration.

본 논문에서는 현직 초·중등 교사의 인공지능 융합교육 역량 강화 및 소양 함양을 위한 인공지능 소양교육 프로그램을 개발하고 이를 적용하여 인공지능 융합교육 관심도에 미치는 영향을 검증하였다. 검사도구는 Hall et al.(1979)의 관심중심수용모형을 기반으로 George, Hall & Stiegelbauer(2006)이 개발한 관심단계 설문 척도를 사용하였다. 인공지능 소양교육 프로그램 적용 전, 후 인공지능 융합교육에 대한 관심도를 분석한 결과, 프로그램 적용 전, 후 모두 비사용자의 유형이 나타났으나 전반적인 관심도는 적용 전에 비해 상승하였다. 인공지능 소양 교육 프로그램의 만족도 결과를 분석한 결과 대부분의 영역에서 만족한다는 응답이 도출되었으나, 인공지능과 산업의 융합 및 적용 사례에 대해서는 다소 만족도가 떨어지는 경향이 나타났다.

In this paper, we establish the convergence of semigroups that are strongly continuous on (0, $\infty$). By using Laplace transform theory, we show some properties of semigroups and the convergence result.

A local convergence result is provided for the continuous analog of Newton's method in a Banach space setting. The radius of convergence is larger, the error bounds tighter, and under the same or weaker hypotheses than before [12].

This paper deals with the model of natural sciences and engineering's convergence education. Recently, convergence education's necessary is needed since the most of new products are designed and produced based on the convergence technology. But our country's education system is keeping existing education process. This make industrial world undurable to employ the current graduated students. Also in view of educational world, they have no proper convergence education model for their students. In this paper, to solve the non-existing convergence education model, we derive the a few convergence education model and list up their model each. This result will be helpful for the introducer of the convergence education system.

This study researches the application methods of Wearable Technology (WT) realizing the convergence of Design and Electronics that could broaden the fashion expression boundaries to correspond to current convergence trends. For this, students in the Department of Fashion design and the Department of Electronics conducted an oriented convergence-design-workshop. The initial step of the workshop, included a lecture on WT including existing cases and brainstorming. As a result, two types of concepts; 'Light' using the lighting technology and 'Complex' using transforming and lighting technologies together were generated. Designers created garments that did not externally expose digital devices and engineers then configured basic systems with the minimum size of the devices applying. At the development stage, designers constructed internal structures of garments which do not influence the comfort situation and activities of those wearing the garments. Engineers then adjusted and finished the fashion prototypes' whole WT systems drawing on designers' guidelines. As the result of this study's workshop, the fashion prototypes were extracted by collaboration according to WT concepts; therefore, there could be the promising potential to broaden fashion expression boundaries through the application of WT.

The rate of convergence for an almost surely convergent series $S_n={\Sigma^n}_{i-1}X_i$ of independent random variables is studied in this paper. More specifically, when S$_{n}$ converges almost surely to a random variable S, the tail series $T_n{\equiv}$ S - S_{n-1} = {\Sigma^\infty}_{i-n} X_i$ is a well-defined sequence of random variables with T$_{n}$ $\rightarrow$ 0 almost surely. Conditions are provided so that for a given positive sequence {$b_n, n {\geq$ 1}, the limit law sup$_{\kappa}\geqn | T_{\kappa}|/b_n \rightarrow$ 0 holds. This result generalizes a result of Nam and Rosalsky [4].

We discuss complete convergence of weighted sums for arrays of ø-mixing random variables. As application, we obtain the complete convergence of moving average processes for ø-mixing random variables. The result of Baum and Katz (1965) as well as the result of Li et al. (1992) on iid case are extended to ø-mixing setting.

Virtual reality applications in Head-Mounted Displays require high frame rates and low latency rendering techniques. Ray tracing offers many benefits, such as high-quality image generation, but has not been utilized due to lower performance than rasterization. But that can obtain good result combined with gaze-tracking technology and human visual system's operation principle. In this paper, we propose a method to optimize the foveated sampling map and to maintain the visual quality through the fast voronoi nearest interpolation. The proposed method further reduces the computational cost that has been improved by the previous foveated sampling. It also smoothes the voronoi boundary using adaptive sibson interpolation, which was not possible in real-time. As a result, the proposed method can render real-time high-quality images with low visual difference.
