Recent Software education topic is GUI programing language 'Scratch' and the open source computing platform plus microcontroller boards 'Arduino'. S4A means a program that controls the Arduino to the scratch. In this paper, development for education content that using S4A and combination the Arduino sensors. and we developed the game in the form of training content by using a variety of tools.

In this paper, we develop a vibration system which can generate diverse vibration effects in realtime by analyzing signals from the sound output of PC. This system is able to detect the occurrences of particular sounds in order to generate corresponding pre-programmed vibration patterns. It contributes to the improvement of the reality and the immersiveness of games and virtual reality applications. In addition, its advantage is to easily add vibration features to applications which were originally developed without consideration for vibration. Our system consists of an external DSP board for signal processing and a vibration pad which can be put on wrists. It is superior to other sound-driven vibration devices because its DSP board can detect more diverse sounds, has higher performance and does not interfere with PC. Also the wrist-wearable vibration pad is able to generate more realistic vibration than other mouse or joystick type devices.

Information present condition is using situation board by manual processing that is consisted of ship arrangement plan and letterpress and magnet etc. in Pyeongtaekhang's deep-sea fishing vessel company. Study that mark open sea far from land ship information of underway 37 ships that is accepted in every time in internet web application environment that is based on Ubiquitous Network in PC that is linked to internet. 3 through practical use of RIA of Flash technology base compose Digital Dash-Board in width grid structure only and do ship sailing addition that is operating in 6 oceans and latitude, hardness indication as well as various informations to do visual display do. Emphasized in dynamic Web Application construction because can heighten the convenience to operator and user, and take advantage of real time data.

Air hockey robots are machine vision systems that allow users to play hockey balls through the camera. The position detection of the hockey ball is realized by using the color information of the ball using OpenCV library. It senses the position of the hockey ball, predicts its trajectory, and sends the result to the ARM Cortex-M board. The ARM Cortex-M board controls a 2- Axis Cartesian Coordinate Robot to run an air hockey game. Depending on the strategy of the air hockey robot, it can operate in defensive, offensive, defensive and offensive mode. In this paper, we describe a vision system development and trajectory prediction system and propose a new method to control a biaxial orthogonal robot in an air hockey game.

Presidential archives have higher historical value than other public documentaries. It is a reliable documentary reflecting aspects of contemporary life and has high value and availability in the education field. This study suggests how to intensify the role as an intelligence service of presidential archives and how to develop the utilized-Presidential Archives mobile education contents in G-learning environments to lead the positive awareness on Presidential archives. After suggesting the 7 levels methods about the development of mobile education contents using presidential archives in G-learning environments, This study shows the case of the applied educational contents on the subject of $5^{th}$ grade at the elementary school. 7 levels methods include pre-planning, pre-design, selecting presidential records, presidential records story-telling, making the storyboard, implementing a game, sharing and assess.

Based on revised 2015 curriculum, diversified SW education methods for elementary school students are researched, developed and applied. However, as most of SW education is based on English text, its coding process may be difficult for low graders of elementary school who are not familiar with English and Math. Under this situation, Kodu game lab based 'icon card board' by which coding could be learnt with ease through game and icon was developed and story activity, coding activity and collaboration activity (SCC) strategy based 17th session SW curriculum was applied and verified. As a result of research, in terms of satisfaction of students for SW class, students more than 86% recognized such class positively and a significant effect was obtained from students' interest level and learning model for coding.

This paper describes our experience to design and implementation of a collaborative system framework that allows to develop certain collaborative applications such as 3D animation, computer game, and industrial design. The collaborative system enables users, who located in geographically long distance, to do collaborative work in a single virtual space. The proposed system basically consists of client and server system. The goal of proposed system is to support scalability, portability, and platform independent. In order to achieve these, the server is implemented in Java platform and is adopted to the hybrid architecture which takes the advantages both in centralized and decentralized collaborative system. We construct the server base on its functional characteristics so called User Manager Server (UMS), Session Manager Server (SMS), and Information Server (IS), The UMS manages the users who are taking part in the collaborative operations. The SMS supports the conferencing in the proposed system. The IS provides the connection methods among the UMSs. For user's convenience, we implement the client using Visual C++ in Windows. We also expend the functions of 3D Studio Max to distributed environment by means of the plug-in module, and facilitate the chatting and white board functions as well.

In this study, we carried out a survey on the degree of recognition for the brand of the Korea Institute of Geoscience and Mineral Resources (KIGAM) to contribute to reestablishing the status and role of KIGAM as an institution that people proud of by effectively delivering KIGAM's various research activities and achievements to people. About 49.9% of external publics recognized that there was relevance between research achievements of geo-technology and national brand. On the contribution of research achievements of geo-technology to promoting Korea's power of science and technology, 42.3% gave positive answers. On research achievements of mineral resources technology, just 14.4% replied they saw such results. As alternatives to promote the degree of recognition for brand, we suggested development of beneficial message, operation of brand management committee, promotion of involvement of research achievements of mineral resources technology about people-friendly subjects, development and distribution of "board game for education on mineral resources technology" for youths, activation of location PR, activation of online Q&A bulletin board, finding out star researchers, and president's PI activities.
