This study defines the pipeline for digital fashion contents production using CLO 3D, a 3D fashion design software that supports virtual clothing visualization as a cutting-edge simulation technology for fashion, and vuforia, a mobile platform augmented reality (AR) development kit for creating AR applications. The proposed production pipeline is organized in a method to produce a virtual clothing model through CLO 3D software through works of patterns, sewing lines, textures, etc., and AR contents based on computer vision techniques using the functions and properties of vuforia development kits in the Unity engine development environment. In addition, we present application method that can be practically utilized from the perspective of practical users, such as fashion designers and directors, by creating a new type of AR digital fashion contents directly as a flow of the defined production pipeline.

As the ubiquitous paradigm that allows users to access the Internet anytime and anywhere is expanding, the expectation and interest of the Internet is increasing. As interest in the Internet has increased, interest in open source hardware has also increased. As a result, the maker, who is a creator who actually uses the digital production tools to create a product that he thought, is emerging as a new trend. As these makers shared how to make products, the 'maker movement', an open source manufacturing movement, spread. In the case of the domestic market, the government's policy support is also stimulating the maker movement. However, compared to developed countries, there is not enough awareness and environment of maker culture, and only open platform hardware and software are used without special education / development equipment or kit for maker.

본 논문에서는 자율신경망 중 ART2(Adaptive Resonance Theory 2)를 이용하여 지문의 매칭알고리즘에 적용하였다. 지문의 영상을 센서로부터 입력 받아, 전 처리와 후처리 과정을 거친 후 각각의 지문에 대한 특징값을 구하고, 지문 영상을 분류 및 매칭 할 수 있도록 하였다. 다음으로 제시한 알고리즘을 바탕으로 PC(Personal Computer) 없이 독립적으로 사용 할 수 있는 실시간 임베디드 지문 인식 시스템을 구현 하였다. 실시간 임베디드 지문 인식 시스템 설계에 있어 크기와 기능면을 고려해 메인 모듈의 프로세서로 최근 신호 처리에 많이 사용되고 있는 DSP(Digital Signal Processor)를 사용 하였으며, 지문을 입력 받기 위한 센서로는 반도체 지문 센서를 사용하였다. 메인 모듈과 센서를 가지고 간단한 디스플레이 및 통신 테스트를 위해 PIC Micro-Processor를 사용해 컨트롤 보드를 제작하여 간단한 인식 테스트를 하였다. 제작한 보드를 가지고 다양한 어플리케이션이 가능하나, 본 논문에서는 하드웨어나 소프트웨어 개발에 사용 가능한 RDK(Reference Design Kit)를 최종으로 구현하였다.

The main work of this paper are the manufacture of six degree of freedom industrial robot control hardware of 16 bit CPU and the development of five motion control software. The work would draw on KIT of Robotics Laboratory whose extensive experience in these areas; in particular the 68000 assembler and Modula-2 languages, and existing robot control systems. We found that this controller is good for the robot controller of PID types. But, for the use of self-tuning algorithms and real time calculations we need 32 bit CPU robot controller such as MC 68020 microprocessor.

As non-face-to-face activities have become commonplace, online video conferencing platforms have become popular collaboration tools. However, existing video conferencing platforms have a structure in which one side unilaterally exchanges information, potentially increase the fatigue of meeting participants. In this study, we designed a video conferencing platform utilizing virtual reality (VR), a metaverse technology, to enable various interactions. A virtual conferencing space and realistic VR video conferencing content authoring tool support system were designed using Meta's Oculus Quest 2 hardware, the Unity engine, and 3D Max software. With the Photon software development kit, voice recognition was designed to perform automatic text translation with the Watson application programming interface, allowing the online video conferencing participants to communicate smoothly even if using different languages. It is expected that the proposed video conferencing platform will enable conference participants to interact and improve their work efficiency.

The informatization of Korea is accompanied by the great growth of new strategic export industry, as of mobile phone or semiconductor LCD. Speaking to the situation of mobile phone, Motorola swept over the American domestic market in the beginning of 1990s, digital mobile communication as CDMA developed swiftly in Korea. In 1996, the first year's CDMA users of Samsung were merely one million, nevertheless, the world's sales in the first half of this year is up to 92 million. In this p aper I design 3D application based on J2ME and implement a freely removable 3D object which happened in a 3D scen e by receiving the keyboard response of mobile device with WTK (Wireless ToolKit) simulator. It contains benefits of improvement of relative speed and high-level functionality such as scene graph, keyframe animation, etc.

This paper describes the design and fabrication of magnetic levitation kits for use in the hands on experiments of automatic control, digital control and microprocessor applications in the division of mechatronics in Samcheok university. The kits are developed inspired by MIT's design, but it is designed on the digital basis, whereas MIT's is designed on the analog basis. As a result, the kits can be monitored and controlled on the analog and digital control techniques. Furthermore, the cost of kit components is comparable or lower to that of MIT design. And the kits can be controlled with magnetic hall sensors and/or infrared sensors, which provides more versatile experience on the use of sensors and signal filtering to the students. The design is fabricated and tested by authors and will be provided to the students as lab projects. The kits will be intentionally presented with a device that is poorly instrumented and poorly compensated. And the students are expected to analyze sensor signal and controller performance, and then, perform compensator design and signal filtering.
