In order to solve the complicated problems faced by the spread of diversified information devices and changes in the user environment in recent years, the importance of training creative talent as well as the need for interdisciplinary convergent approach have emerged. As a future technology development project, convergence education with the design sector for training creative talent in the IT field is also urgent. In this study, we recognized the importance and problems of the convergent approach between IT and design sector by examining the convergence theory and cases with a focus on effective creativity development and sought a new direction for convergence education in the future by investigating the awareness on the convergent approach of college students and analyzing the results. This will be able to have significance as a basic study for discovering creative and innovative convergent talent in the IT and design sector in the future and strengthening basic competence.

The purpose of this research was to analyze the convergent approaches for creativity in elementary mathematics textbooks in Korean and the united States. Convergent approaches have emphasized since NCTM(2000) consistently includes 'connections' as an important factor in mathematics curriculum and KOFAC(Korea Foundation for the Advancement of Science & Creativity) initiated the STEAM(Science, Technology, Engineering, Arts, and Mathematics) in mathematics and science education. For this research, two elementary mathematics textbooks were analyzed focused on their contexts and contents: Korean National Elementary Mathematics Textbooks and Navigations in Numbers, Data, and Space. In both textbooks, it was not easy to find so called the convergent approach in a real sense, but they use some contexts for connections between mathematical concepts and real world phenomena. For the enhancement of convergent approaches in mathematics education, we need to have a broader sense in the convergent approaches and develop various meaningful materials.

The Reed-Muller code is one of the efficient algorithms for multiple bit error correction, however, its high-computation requirement inherent in the decoding process prohibits its use in practical applications. To solve this problem, this paper proposes a graphics processing unit (GPU)-based parallel error control approach using Reed-Muller R(r, m) coding for real-time wireless communication systems. GPU offers a high-throughput parallel computing platform that can achieve the desired high-performance decoding by exploiting massive parallelism inherent in the algorithm. In addition, we compare the performance of the GPU-based approach with the equivalent sequential approach that runs on the traditional CPU. The experimental results indicate that the proposed GPU-based approach exceedingly outperforms the sequential approach in terms of execution time, yielding over 70× speedup.

Purpose This study aims to develop a job model for data convergent talents to meet the rapidly changing demands of the data industry. To create a job model, we first define and categorize data convergent talents with balanced competencies in data technology and domain knowledge, and then develop a job model by investigating job areas, scope, activities, and competencies. Design/methodology/approach The research is conducted using the following procedures and methodology. First, we conduct a current status survey on data talent demand, data talent policies, data talent programs, and curricula at home and abroad; second, we collect opinions on the jobs and competencies required for data convergent talents and curricula for talent development through in-depth interview with experts; and third, we present the job areas and job activities of data convergent talents derived from the previous status survey and expert opinions based on the National Competency Standards(NCS). Findings The research findings indicate that there are total of six job roles for data convergent talents, including data scientist, data planner, data architect, data developer, data engineer, and data analyst. It was observed that each of these roles requires the development of common competencies within their respective fields, followed by a need for further specialization into specific competencies within each professional domain.

Customary way of thinking may be the most major stumbling block to creative thinking in basic design education in the information and network era. The basic design education was used to be based on personal experience or subjective ideas, but these days, the role of divergent thinking and convergent thinking which provide the basis of creative techniques has been closely examined. Going beyond a divergent thinking and directly starting a convergent thinking means bypassing the design process of the existing basic design education. Though preceding studies considered various creative techniques apart from divergent thinking and convergent thinking, this study presumed that complementing the most typical methods of divergent thinking and convergent thinking may result in the same basic design education effect. So, what approach must be used to the design? The way of thinking needs to change. For that, we try to apply the mapping to basic design education. It must encompass interactive thinking which includes immaterial elements and communication. Divergent thinking can begin with the accurate understanding of current state, and the created current state resolves the design process that needs to be a certain thing. The purpose of this study was to present the method for applying the mapping techniques to basic design education based on divergent and convergent thinking which provides the basis of creative ideas.

A hologram projects a 3 dimensional video as same as a real subject and it is made by principles of holography. Many researches about holographic technology have been developed. Studies for visualization of 3D videos, holographic storages, and optical media have proceeded mostly in engineering. It is hard to find any researches about the convergent system from the viewpoint of interactive elements and motion graphic design such as this paper's concept. Most studies of augmented reality have been developed in the domain of technology and education but the field of content production. AR has been convergent with various fields and media, so it is time to make an active progress in the study of convergent content development. The goal of this study is to develop cultural contents and create new values through the convergence of holography and AR. The purpose of this paper is to propose the way of developing the convergent type of cultural contents and construct the production system by the new approach to users using the convergence technology of holography and augmented reality.

Participatory Design (PD) community recognized that identification of use case scenarios describing possible uses of the future system is beneficial for users to identify their system requirements. However, brainstorming is a typical methodology for users to create use case scenarios during PD session, which heavily depend on the people skill and experiences of the analysts. The objective of this study is to develop a theoretical framework for automatic generation of requirement scenarios. Automatically generated scenarios serves as a menu of the possible user requirements from which user group can start to generate ideas about their requirements. The convergent approach taken here is novel in that the generated scenarios describe system requirements as well as the business process requirements in which the system operates. A context-sensitive grammar is used to generate the context relevant requirement scenarios.

The fuzzy linear programming(FLP) is the useful approach to many real world problems under uncertainty. This paper deals with a FLP whose objective value is fuzzy. And the right hand sides of convergent equality constraints are fuzzy numbers. We assume that the membership function of the objective value is piecewise linear and those of the right hand side are trapezoidal. Each of these trapezoidal functions can be algebraically replaced with three linear functions. Then the FLP problem is transformed into the Zimmermann's symmetric model. The fuzzy solution based on the max-min rule can be obtained by solving the crisp linear programming problem derived from the symmetric model. A numerical example has illustrated our approach. The application of our approach to the inconsistent linear system can enable generate us to get define the useful and flexible inexact solutions within acceptable tolerance. Further research is required to generalize the membership function.

This study develops an approach to assign numbers of facilities (rectangular shape) in a given plant and compares the test results by proposed approach with those by approaches in the literature. An improvement approach is proposed to minimize material handling cost given initial layout. Like popular heuristic approaches, the developed heuristic approach employs interchange routine to improve material handling cost in current layout. Horizontal interchange and vertical interchange procedures are applied to obtain better solution. Also, it is possible to rotate facility layout when the sizes of both facilities are same. However, the proposed approach generates good solutions without shape distortion. That means the shape of facilities remains rectangle in the final solution. In addition, the improve approach can find global optimal solution from local optimal solution by applying Tabu search technique. Based on 25 test problems in the literature, we obtained better solutions than other facility layout approaches in the literature when there are many facilities.
