  • DNA 컴퓨팅은 분자 수준(molecular level)에서 연산을 수행한다. 따라서 일반적인 실리콘 기반의 컴퓨터에서와는 달리, 순차적인 연산 제어를 보장하기 어렵다는 특징이 있다. 그러나 DNA 컴퓨팅은 화학반응에 기초한 연산이기 때문에, 실험자가 의도한 연산을 많은 수의 분자에 동시에 적용할 수 있으므로 실리콘 기반의 컴퓨터와는 비교할 수 없는 병렬 연산을 구현할 수 있다. 병렬 연산을 구현하고자 할 때, 일반적으로 연산에 사용하는 모든 DNA 분자들을 대상으로 연산을 구현할 수도 있다. 그러나 전체가 아닌 일부의 분자들을 상대로 연산을 수행하는 것 역시 가능하며 이 때 자연스러운 방법으로 사용할 수 있는 방법이 배깅(Bagging)이나 부스팅(Boosting)과 같은 앙상블(ensemble) 계열의 학습 방법이다. 일반적인 부스팅과 달리 가중치를 부여하는 것이 아니라 특정 학습자(learner)를 나타내는 분자들을 증폭한다면 가중치를 분자의 양으로 표현하는 것이 가능하므로 분자 수준에서 앙상블 계열의 학습을 구현하는 것이 가능하다. 본 논문에서는 앙상블 계열의 학습 방법 중 특히 부스팅의 효과를 DNA 컴퓨팅에 응용하고자 할 때, 어떤 방법이 가능하며, 표현 과정에서 고려해야 할 사항은 어떠한 것들이 있는지 고려하고자 한다. 본 논문에서는 규모를 사전에 한정할 수 없는 진화 가능한 그래프 구조(evolutionary graph structure)를 학습할 수 있는 방법을 찾아보고자 한다. 진화 가능한 그래프 구조는 기존의 DNA 컴퓨팅 방법으로는 학습할 수 없는 문제이다. 그러나 조합 가능한 수를 사전에 정의할 수 없기 때문에 분자의 수에 상관없이 동일한 연산 시간에 문제를 해결할 수 있는 DNA 컴퓨팅의 장정을 가장 잘 발휘할 수 있는 문제이기도 하다.개별 태스크의 특성에 따른 성능 조절과 태스크의 변화에 따른 빠른 반응을 자랑으로 한다. 본 논문에선 TIB 알고리즘을 리눅스 커널에 구현하여 성능을 평가하였고 그 결과 리눅스에서 사용되는 기존 인터벌 기반의 알고리즘들에 비해 좋은 전력 절감 효과를 얻을 수 있었다.과는 한식 외식업체들이 고객들의 재구매 의도를 높이기 위해서는 한식 외식업체의 서비스요인, 식음료요인, 이벤트 요인 등을 강화함으로써 전반적인 종사원 서비스 품질과 식음료품질을 높이는 전략을 취해야 한다는 것을 시사해주고 있다. 본 연구는 대구 경북소재 한식 외식업체만을 대상으로 하여 연구를 실시하여 연구의 일반화와 한식 외식업체를 이용하는 이용 고객들이 한식 외식업체를 재방문하는 재구매 의도가 발생하는데 있어 발생하는 과정을 설명하는 종단적 연구를 실시하지 못한 한계점을 가지고 있다.아직 산업 디자인이 품질경쟁력에 크게 영향을 미치는 성숙단계에 이르지 못하였음을 의미한다. (2) 제품 디자인에게 영향을 끼치는 유의적인 변수는 연구개발력, 연구개발투자 수준, 혁신활동 수준(5S, TPM, 6Sigma 운동, QC 등)이며, 제품 디자인은 우선 품질경쟁력을 높여 간접적으로 고객만족과 고객 충성을 유발하는 것으로 추정되었다. 상기의 분석결과로부터, 본 연구는 다음과 같은 정책적 함의를 도출하였다. 첫째, 신상품 개발과 혁신을 위한 포괄적인 연구개발 프로젝트를 품질 경쟁력의 주요 결정요인(제품의 기본성능, 신뢰성, 수명(내구성) 및 제품 디자인)과 연계하여 추진해야 할 것이다. 둘째, 기업은 디자인 경영 마인드 제고와 디자인 전문인력 양성을, 대학은 디자인 현장 업무를 통하여 창의력 증진과 기획 및 마케팅 능력 교육을, 정부는 디자인 기술개발 및 디자인 교육지원의 강화를 통하여 각각 디자인 경쟁력$\righta

  • Robots evolve from tools to information media since they generates information by interacting with human. As studies on robot-aided education are still in a starting phase, attempts need to be made to use robots for educational purposes and to investigate the effects of the use. It was showed that robot-aided learning was friendlier than other media assisted learning, and especially effective for motivating children. We developed the prototype robot Jenny that can help teachers as a educational media in class(i.e. as a T.A. robot, it can present robot contents on its chest to screen and explain about it when teacher asks). is a schoolmate for 5th or 6th grade children or an elder schoolmate for the rest. We performed the field trial at an elementary school. We carried out 9 classes for three subjects(english, korean, music) with -students in $4th{\sim}5th$ grade. They thought Jenny who was 13 years old as an elder schoolmate in 6th grade. Also, a significant difference was found in the interest and concentration of experimental groups from controlled groups.

  • Today, SNS exists as the most influential medium. A variety of designs are being produced in the context of numerous SNS marketing designs and the increasing exposure of ads to SNS and portal sites. Recognizing the current status of sns advertising design, which is heating up more than a decade ago, we will study strategies to introduce an important part of education to be conducted in universities and the current way in which it is used and produced. Modern SNS marketing designs include promotional posters, card news, and banner ads, and are evolving into various forms and content that are combined with advertisements. In communicating or sharing information, the importance of real-time advertising product work and the saving of caustic costs are important. This requires a diversification of university education, as well as a change in quality and speed of production. When the graduates of SNS Design Production Education Development Plan and design work were carried out, they conducted a study on the education section where real-time work is possible to proceed to the industrial field. Through this research, we would like to consider the development of SNS marketing design personnel and the practical implications of training methods.

  • We have examined the perception of teachers and students in elementary schools toward the frontier science and analyzed corresponding contents in science textbooks in Korea and the U. S. in order to promote a good guidance for the frontier science education. We prepared separate questionnaires for teachers and children, respectively, and analyzed the responses obtained from 244 teachers and 1,000 students in five elementary schools. For the analysis of how to introduce the frontier science, we investigated textbooks such as Science, Society and Practical Arts of Korean elementary school, and an American science textbook published by Scott Foresman. This study revealed that teachers are well aware of the importance of the frontier science, however, they are inactive in conducting the subject in class rooms because of their insufficient scientific knowledge and poor environment for teaching. It has been found that children had strong interest in the frontier science, however, opportunities to learn the topic are not properly provided. The frontier science m the American science textbook turned out to be more systematically introduced than that in Korean ones.

  • Analogy, based on a similarity, is to infer the properties of the similar object from properties of an object. It can be a very useful thinking tool for learning mathematical patterns and laws, noticing on relational properties among various situations. The purpose of this study, when manipulating hint condition, figure and table conditions and the amount of original learning by using algebra word problems, is to verify the effects of analogical transfer in solving equivalent, isomorphic and similar problems according to the similarity of source problems and target ones. Five study questions were set up for the above purpose. It was 354 first grade students of S and G middle schools in Seoul that were experimented for this study. The data was processed by MANOVA analysis of statistical program, SPSS 10.0. The results of this studies would indicate that most of the students would be poor at solving isomorphic and similar problems in the performance of analogical transfer according to the similarity of source and target problems. Hints, figure and table conditions did not facilitate the analogical transfer. Merely, on the condition that amount of teaming was increased, analogical transfer of the students was facilitated. Therefore, it is necessary to have students do much more analogical problem-solving experience to improve their analogical reasoning ability through the instruction program development in the educational fields.

  • In this paper, we propose a method to solve the difficulties in constructing an environment capable of practical training on the theoretical contents of robot control field. We make a two-wheeled mobile robot with Segway structure using LEGO block. In order to demonstrate the validity of using the developed robot as a practical application of advanced control theory of robotics education such as dynamic system and nonlinear system, the robot takes a stable posture while balancing the change of gravity during running. The results of the experiment are shown. By presenting the results, the robots made using the LEGO block are used for practical training of advanced control theory of robotics. It can be used as a tool.

  • Recently, for the preservation and transmission of cultural heritage, various researches and content development based on technologies such as virtual reality, augmented reality, and extended reality, which are the core technologies of the 4th industrial revolution era, are being conducted. Intangible cultural heritage is variable, unlike tangible cultural heritage, so it changes greatly depending on time and space, and as a result, it is in danger of being discontinued due to the aging and death of the inheritors. In this study, the current status and cases of related realistic content production were collected and analyzed, focusing on statistical data, intangible cultural heritage training centers through search portals, and platform cases. As a result of the analysis, it was found that overall, there were very few cases of use in content and transfer education using intangible cultural heritage. Through this study, we will consider ways to revitalize the effective transfer education of intangible cultural heritage that is on the verge of being cut off from transmission.

  • Convergence technology stimulating participation sharing openness to the public of web 2.0 such as Open-API, Mash-Up, Syndication gives diversity to education field. The convergence in education field means the revolution toward education 2.0 and new education reflecting web 2.0 stream is called 'education 2.0'. Education environment can be the space of social network intimately linked between learners, educators and educational organization. Network technology developed in ontology language makes it possible to educate semantically which understands privatized education service and connection. Especially, filtering system by the reputation system of Amazon and the collective intelligence of Wikipedia are the best samples. Education area can adopt actively because learners as educational main body can broaden their role of participation and communicate bilaterally in the equal position. In this paper, new network architecture in contents linkage is introduced and researched for utilization and analysis of the architecture for web 2.0 technology and educational contents are to be converged. Education 2.0 service utilizing convergence technology and network architecture for realizing education 2.0 is introduced and analyzed so that the research could be a preceding research to the education 2.0 platform foundation.
