We looked at how the damping qualities of epoxy composites changed when different amounts of graphite nanoplatelets (GNP) were added, from 0% to 6% by weight. A mix of free and forced vibration tests helped us find the key GNP content that makes the damper ability better the most. We also created a Representative Volume Element (RVE) model to guess how the alloys would behave mechanically and checked these models against testing data. An Artificial Neural Network (ANN) was also used to guess how these compounds would react to motion. With proper hyperparameter tweaking, the ANN model showed good correlation (R²=0.98) with actual data, indicating its ability to predict complex material behavior. Combining these methods shows how GNPs impact epoxy composite mechanical properties and how machine learning might improve material design. We show how adding GNPs to epoxy composites may considerably reduce vibration. These materials may be used in industries that value vibration damping.

Recently, Modeling and Simulation, which have been received attention in various in dustries such as national defence, eduction and entertainment, have been researched, and related applications have been developed actively. Especially, it is focused on the to chnology of a virtual reality and a virtual simulation which represents the implementation technology for the simulation education related to the e-Learning industry. However, a solution is needed to fulfill the lack of technology and research about standardize d data elements which could be applied to virtual simulation technologies in common. Therefore, this article suggests the virtual simulation data elements to increase the educational effect of a virtual simulation and interoperability of data among LMS through reference to korean and international standards and the result of related area analysis. In other words, this article aims to define the expression of data element and to propose the guideline elements in the virtual simulation scope.

본 논문은 공과대학에서 요소설계 과목에 문제중심학습(PBL : Problem-Based Learning) 활용을 위하여 PBL 문제를 개발하여 수업에 적용하고 PBL 효과를 확인하는데 목적을 두었다. 현대 산업사회에서는 협동 학습 능력, 자율적인 학습능력, 통합지식 활용 능력, 창의 문제해결 능력을 갖춘 인재를 필요로 하고 있다. 대학은 사회에서 요구하는 인재를 양성하기 위해 학습자들에게 문제해결능력 향상과 협동학습의 기회를 제공해 주어야 한다. PBL 활동은 이러한 실천을 위한 적합한 학습 방법이다. 연구대상은 요소설계에 해당하는 '공학설계 1'교과목을 수강한 H대학 2학년 학생 32명이었으며, PBL수업은 15주에 5개의 PBL문제를 적용하였다. 학생들은 주어진 문제의 PBL 활동이 끝날 때마다 성찰일지를 작성하여 제출하였으며, 5번째 PBL문제의 활동이 끝난 후에 강의 평가지를 작성하였다. 연구 결과는 학습내용에 대한 이해(71.87%), 협동학습에 대한 이해(87.5%), 실제적 경험, 문제해결력(90.63%), 프리젠테이션 스킬(96.87%), 자기주도적 학습 능력, 자신감(96.87%)과 같은 다양한 PBL의 효과를 경험한 것으로 나타났다. 학생들은 이 PBL 학습 활동은 현대 산업사회에서 요구하는 미래의 유능한 엔지니어로서의 전문성을 기를 수 있는 중요한 방법이라고 인식하였다.

The purpose of this study is to analyze the traits on the cognitive and affective learning style of university students. CALSIU(The Cognitive & Affective Learning Style Inventory for University School Students) by Kim, E. J. was modified for applying to university students and performed with 399 university students from three universities in Daejeon and Chungnam. Statistical analysis done in this study were ANOVA and Scheffe's test. Findings of the study are as follows : First, the students with high academic achievements have intuitive perception type, whole processing type, and deep storage & recall type. Secondly, the students with low academic achievement have strong non-academic learning type. Third, interaction attitude of affective learning styles is the important element to determine their academic achievement. The students with independent type get high academic achievements. Therefore, instructor should consider the learning styles of students, and it should be used to improve their teaching & learning strategy for better academic achievements of university students.

The purpose of this study is to develop the Public Practice Center's teaching-learning model by applying blended learning strategies which is complementary to the expected problems such as expansion of the educational object and diversity of the curriculum to maximize the educational effect and to analyze activation types of the Practical Practice Center to expand the Public Practice Center's function and role by studying the document. Blended Learning Strategies are established in consideration of the following eight (8) factors ; learning environment, learning purpose, learning contents, learning time, learning place, learning type, learning media, type of interaction. It is redesigned and amended to the KEDI's individual confirmation instruction model for skill learning (1975) which is considered to be effective in the filed of education by applying features, educational contents of the Public Practice Center's teaching and merit of Blended Learning Strategies simultaneous. This model is composed of six (6) steps as shown below; 1. Understanding on the purpose and orientation 2. Observation for demonstration of fundamental skill 3. Ex on-line learning 4. Acquirement of element skill 5. Confirmation for acquirement of fundamental skill 6. After on-line learning. Further to this, this model is designed so that the above eight factors will be applied to the students effectively and the merit of e-learning and off-line practice will be mixed to the learner's expectation and satisfaction.

구성주의교육은 현대지식기반 사회에서 학교교육의 중요한 목표이다. 구성주의는 학습자의 사회적 학교생활을 통해서 지식의 구성이 개인적, 주관적으로 이루어진다고 주장한다. 학습자의 창의성을 바탕으로 하는 지식의 개인적, 주관적 구성은 오늘날 학교교육의 목표를 학습자중심교육으로 발전시키고 있다. 본 연구는 구성주의교육의 원리와 특성을 규명하고, 구성주의교육의 구현요소로서 학교도서관활용수업의 개념과 특성을 살펴보고자 한다. 학교도서관활용수업은 최근 학교현장에서 관심을 받고 있으나 아직은 충분한 단계로 발전하지 못하고 있다. 본 연구에서는 학교도서관활용수업의 범위와 단계를 조사하고 구성주의교육에서 적용될 수 있는 일반적인 특징을 제시하고자 한다. 구성주의교육은 학습자의 실제적(authentic)경험과 체험을 중시하는 학습환경의 조성을 강조하며, 자료중심교육을 바탕으로 하는 토의학습, 문제 중심학습, 프로젝트학습 등의 학습방법이 효과적이다. 학교도서관은 학교의 정보자료센터로서 자료중심교육의 필수적 요소이며, 학교도서관활용수업은 가장 효과적인 자료중심교육의 방법이다.

Above all, the ability to solve problems must be emphasized as a basic skill of mathematics, but it is neglected when we teach. In this study, learning task means ［same meaning］ ［same form］ ［same technique］, so I tried to extend mathematical scholastic ability of the students as an extensional problem solving that is a basic element of mathematics. The purpose of this study is the investigation of level type learning, using the basic learning elements to extend thinking ability. From the constructed hypothesis as follows and then implement it. I selected basic learning elements from an analyzed textbook and then task learning material was created for each level type learning. The problem solving ability will be extended through the level type learning of the small group, using the level type learning task material. The conclusions this study are as follows. The level type learning in small group learning, using and making level type learning material, having basic learning elements in analysed text are. Basic learning content is understood clearly and deeply, so, fundamentally, it is effective in achieving the problem solving in mathematics. It is an effective method to achieve the meta-cognitive faculty because achieved the expected method of solving problems and resulted in the true learning of content.

This research aimed for revealing social interaction-based environmental learning elements at the natural history museum. First, we carried out a survey of the perceptual change about 'the environment' concept. It was for confirming whether environmental learning occurred in visiting. Second, we found environmental learning elements through analyzing dialogues among small group members during looking around the museum. Social interaction-based environmental learning elements were classified into five; knowledge, affection, value, skill, behaviour. Each environmental learning element included several sub-elements, so we revealed totally 9 environmental learning sub-elements. By results, we said characteristics and possibility of the natural history museum as an informal environmental educational institution. It is meaningful for extending areas of environmental education.

In this paper, we notice the fact that a human learning process is characterized by a process under a natural language environment, and discuss an approach of learning based on indirect linguistic instructions. An instruction is interpreted through some meaning elements and each trend. Fuzzy evaluation rule are constructed for the searched meaning elements of the given instruction, and the performance of a system to be learned is improved by the evaluation rules. In this paper, we propose a framework of learning based on indirect linguistic instruction based learning using fuzzy theory: FULLINS(FUzzy-Learning based on Linguistic IN-Struction). The validity of FULLINS is shown by applying it to helicopter flight control.
