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.

퍼지 선형계획법은 불확실성하에서의 문제들을 해결하는데 유용한 의사결정 모형이다. 본 연구에서는 목적함수 값이 퍼지수이고 우변 상수도 퍼지수인 융합 등식 제약식을 갖는 퍼지 선형계획법 문제를 다룬다. 연구의 목적은 퍼지 해를 정의하고 그것을 구하는 절차를 모색하는 것이다. 목적함수 값에 대한 소속 함수로 부분 선형함수를, 제약식의 소속 함수로는 사다리꼴 함수를 도입한다. 사다리꼴 함수는 구간별 선형 함수 들로 나누어 나타낼 수 있다. 따라서 모든 소속 함수들을 선형식 들로 대체함으로써 퍼지 선형계획 모형을 Zimmermann의 대칭 선형 모형으로 바꿀 수 있다. 여기에 최대-최소 기준을 적용하여 일반 선형계획법 문제를 도출해 내고, 이 문제의 최적해로부터 원 문제의 퍼지 해를 얻게 된다. 본 논문에서는 사다리꼴 소속 함수에 대해 살펴보았는데 앞으로는 오목 부분 선형함수와 같은 좀 더 일반화된 소속 함수에 대한 연구가 필요하다.

이 연구에서는 주어진 공장의 공간에 여러 개의 직사각형 형태 부서의 위치를 할당하고 문헌에 있는 다른 설비배치 기법과 비교하고자 한다. 이 연구는 초기 설비배치가 주어졌을 때 물류비용을 최소화하는 개선적 접근방법을 제시하였다. 기존의 문헌에 있는 접근 방법과 같이 이 연구에서 제시된 접근 방법도 하나의 설비배치에서 부서를 교환하여 더 좋은 해를 찾고자 하였으며, 물류비용을 개선하는 자기발견적 절차를 적용하였다. 수직적 교환, 수평적 교환, 통합 절차 및 분리 절차를 통해 더 좋은 해를 발견할 가능성을 높이고 크기가 같은 설비의 경우에는 설비 배치의 회전도 가능하게 하였다. 그러나 CRAFT와 달리 이 연구에서 제시되는 알고리즘은 설비 형태의 왜곡이 일어나지 않고 직사각형을 유지하는 좋은 해를 제공한다. 또한 Tabu 탐색기법을 활용하여 지역적인 최적해에서 전체 최적해를 찾아가고자 하였다. 문헌에 있는 25개의 설비배치 문제에 대하여 다른 접근 방법과 비교한 결과 제시된 접근방법이 설비의 수가 많을 때 훨씬 더 좋은 해를 제공하는 것으로 나타났다.
