This paper deals with AI education service that enables developers who have completed basic programming education to program in C/C++ language in order to learn big data and artificial intelligence. In addition, a customized development environment configuration system according to the development environment and how the user implements and tests artificial intelligence are explained. And also it has a function to check the effect on artificial intelligence through manipulation of various internal parameters. It is expected that it will be possible to develop artificial intelligence education services without language restrictions through networks in the future.

The purpose of this study was to verify the usefulness of the Mathcad program as a tool for the studying and teaching the sport biomechanics. A projectile motion was analyzed because it is the one of the most popular motion in sports activities. A 3 dimensional CG data for the high jump bar clear phase was used to calculate the initial velocity vector of the CG. Linear regression function and other functions such as cubic spline and derivative of Mathcad were used to calculate this vector. Finally, the approach angle to the bar and peak jump height was calculated. Programming in Mathcad was relatively easy compare to traditional computer language such as Fortran and C, because of the unique documentation method of Mathcad. Additionally the 2 and 3 dimensional graph function was very easy and useful to describe the mechanical data. If the use of Mathcad program is more popular in the field of sport biomechanics, it could greatly contribute to overcome the limit of research caused by the lack of proper programming ability.

본 연구에서는 21세기 지식정보사회에 학생들의 창의력 향상을 위하여 MSRDS에서 제공하는 에디터인 VPL(Visual Programming Language)를 이용한 로봇 프로그래밍 학습이 창의력에 미치는 효과를 연구하였다. VPL은 로봇 애플리케이션 개발을 프로그래머가 아닌 학생들도 쉽게 사용할 수 있도록 MSRDS에서 제공하는 프로그램이며, 이를 시뮬레이션과 연결시켜 로봇 하드웨어가 없이 손쉽게 학습을 할 수 있게 하였다. 이를 위하여 VPL에서 사용하는 기본 Activity를 이용하여 프로그래밍의 구문을 자연스럽게 학습할 수 있는 수업 내용을 개발하였으며, 연구 대상은 충청남도 B군에 위치한 B공고 3학년의 컴퓨터응용관련 학과 1개반을 대상으로 C언어를 이용한 기존의 마이크로 장비 프로그래밍 수업과 VPL을 이용한 로봇 프로그래밍 수업을 상호 비교하려고 한다. 이 연구에서는 VPL을 통하여 손 쉽게 프로그래밍을 하고 흥미가 유발되어 자신이 생각한 대로 로봇의 동작을 구현하는 과정에서 자연스럽게 문제해결능력이 신장된 것을 확인하고자 한다.

ZigBee is a technology that is being rapidly developed since its power consumption is low and the stability of its communication is high. However, documented data which is coded using conventional programming languages such as C or assembly programming language would not be able to fulfill the various requirements upon application development by ZigBee. Unified Modelling Languge (UML) could be one of the alternatives to solve this problem. UML provides a variety of diagrams by which the results of the software development can be presented visually and by which the developers can communicate more spontaneously. This paper shows the results of an ongoing study into the application of model-driven methods for ZigBee Application. Also, this paper shows that this approach is feasible by comparing memory usage, latency, and power consumption of UML modelling code with those of handwritten code.

GRAFCET is the program language for a sequential control and utilized in the description of sequence of a process. This study is to implement GRAFCET editor and compiler for personnel computer. The GRAFCET editor module is developed to use as menu-driven method based on the graphic screen and the graphic symbol. So, users can use it interactively. The GRAFCET compiler module analyzes the already drawed GRAFCET diagram, then translates it to Z80 assembly code. After generating Z80 machine code from assembly code, we can send the outputed machine code file to Z80 one-board computer through RS232C. We have developed the GRAFCET programming tool to utilize under IBM PC/AT with the VGA monitor, and it may be contribute to low cost automation system.

In this paper, we implemented the Android NDK porting application with Eclipse(JDK) ADT and TinyOS 2.0. TinyOS and Cygwin are component based embedded system and an Open-source basis for interfacing with sensor application from H-mote. Cygwin is a collection of tools for using the Linux environment for commercially released with x86 32 bit and 64 bit versions of Windows. TinyOS-2. x is a component based embedded OS by UC Berkeley and is an Open-source OS designed for interfacing the sensor application with specific C-language. The results of Android porting experiment are described to show the improvement of sensor interfacing functionality under the PXA320 embedded RTOS platform. We will further more develop the software programming of Android porting under Embedded platform and enhance the functionality of the Android SDK with mobile gaming and kernel programming under sensor interfacing activity.

This paper compares the Java program environments and NDK program environments in the Android system. This paper experiments that how much is the performance enhancement in the NDK C programming of the Android system. I program sum of 1 to n for Java program and NDK C program. I experiment whether the influence an effect on a performance by changing n value. In experiment, NDK C program is over 50% performance enhancement than Java program.

It is possible to increase integrated thinking and problem solving ability ultimately through STEAM education. This study developed STEAM model to apply to subjects and scratch knowledge education that sixth grade students in elementary schools can learn each subject through STEAM learning by applying scratch programming and it was applied and analyzed during regular classes and afterschool classes for sixth grade students. As a result, it was possible that about 70% of sixth grade students, the subject of model application were able to do STEAM learning initiatively by applying scratch program. Other 30% of the students were able to do STEAM learning partially through scratch. As for the achievement assessment of STEAM learning, it was evaluated that most of the students for the evaluation subjects got satisfactory achievement level by getting overall average 7.83 out of ten. Thus, it is considered that STEAM learning model by applying scratch is very superior that applying existing programming language such as C, BASIC etc.

Manufacturing Message Specification (MMS) is designed as a communication standard protocol, ISO/IEC 9506, on factory automation for messaging between heterogeneous programmable unit controller, PLC, NC, Robot, of different vendors on the networks. MMS is also a standard protocol of OSI reference model application layer, In this paper, we show an implementation of MMS over TCP/IP using ANSI-C programming language on the unix environment, and make java classification using java native interface (NJI) with MMS library. The use of java classification provides a basic environment ot overcome a difficult programming with different MMS application programming interface (MMS-I) which requires a siklled programming technique of graphic user interface (GUI). In this paper, we implement a MMS application program of the automated assembly model for printed circuit board based on WWW which shows the operation, control and monitoring of real manufacturing device (RMD) with web browser providing users for consistent user interface.
