This study developed a sound art programming course using pure data to foster computational thinking and convergence of art and technology in college students who are non-computer majors. This paper presents an example of operating a curriculum that designed and developed a sound art-centered music programming subject using Pure Data, derives educational outcomes and improvement measures for classes, and presents a creative convergence education program of technology and art. It has a purpose. For the study, we looked at examples of educational programs that combine art and technology, as well as pure data and sound art, and based on this, we designed and developed a sound art programming course for non-majors. The curriculum was operated based on the developed subjects, and the results showed increased interest in programming through art and technology convergence classes, active class participation through autonomous choice, creation of a new perspective on art, improvement of computational thinking skills, collaboration and communication. The educational effect of ability enhancement was confirmed. We expect that this study will be able to present a new perspective on the convergence education of art and technology, including artistic diversity and understanding of new media according to the development of media.

This paper was written for the purpose of using as the theoretical basic data of judgment in the situation that there is a growing demand for intelligent design theory to be taught in public schools along with evolution theory. In order to verify the possibility that intelligent design theory, which has little empirical evidence unlike evolutionary theory, could be a scientific theory, what intelligence is and whether the trace of intelligence is actually found in nature was confirmed through literature. If intelligent elements, which are traces of intelligence in nature, are discovered empirically in nature, then intelligent design theory can be recognized as a scientific theory and can also be taught in public schools. The identity and traces of intelligence were found in relevant literature and the traces are found not only in various artificial products derived from human beings such as thinking, knowledge, and civilization, but also in all phenomena of nature. Based on these results, this paper provides a discussion on how the evolutionary theory and intelligent design theory should be handled in the field of school education, as well as how to resolve the conflicts between evolutionary theory and intelligent design theory.

Since aging population in Korea is rapidly progressing, the need for improving the life quality of the elderly has been increasing. Accordingly, in order to respond in a residential environment improvement and behavior change for the elderly, architecture design and construction methods have become converted into a modular construction method and various IT systems for the elderly have been proposed. Unlike current residential design techniques for the elderly in which architectural design techniques are performed separately with IT system design, the methodology for converging architectural design techniques with IT has not been discussed and proposed. Therefore, this paper extensively studies about requirements for converging architectural design techniques with IT such as elderly behavior, residential IT Service plan factor analysis, and residential modular construction method including IT services.

This paper design a role-based access control model that can resolves the complicated problems of access control requirements. In this paper, we designed an access control model which can control a permission making use up role-based access control, can guard the confidentiality, integrity and availability of information and can control illegal information flow. The designed access control model can protect resources from unauthorized accesses based on the role, multi-level security policies of security level, integrity level and ownership.

본 논문에서는 고속 저전력 곱셈기에 적합한 CPA(Carry Propagation Adder)부분의 ENMODL (Enhanced NORA MODL) 설계방식을 제안한다. ENMODL 설계방식은 반복성이 많은 CLA(Carry-Look-ahead Adder) 가산기와 같은 회로에서 많은 면적을 줄일 수 있고 동작 속도를 빠르게 할 수 있다. 따라서 본 논문에서는 저전력 고속 곱셈기에 적합한 CPA 부분을 ENMODL CLA 가산기로 설계했고 현대 0.6$\mu\textrm{m}$ 2-poly 3-metal 공정파라미터를 이용하여 HSPICE로 시뮬레이션 하여 회로의 성능을 확인하였다. 또한, CADENCE tool을 이용하여 16비트 곱셈기에 적합한 ENMODL CLA를 레이아웃 하여 칩 제작 중에 있다.

In this paper, a baseband module of the spread spectrum system with FPGA is designed. A spread spectrum system spreads the signal bandwidth necessary for information transmission. We focused on the design of FEC decoder, especially the convolutional code fo constraint length K=3, rate R=l/2, is designed. For the VHDL design the Xilinx Foundation 3.1 is used. As results, a spread spectrum modem with convolutional coding is designed and we have plan to apply this modem to short distances wireless communication.

각종 범용 컴퓨터 및 디지탈 신호처리에서 중요한 역할을 하는 16비트 정수형, 2의 보수 형태의 곱셈연산을 수행하기 위한 고속 승산기구조를 설계하고 시뮬레이션 하였다. 부분곱을 합하는 부분은 일반적으로 전체 곱셈기 처리 지연시간의 절반정도를 차지하므로 이 부분의 설계방법이 곱셈기의 궁극적인 속도향상에 직접적인 영향을 미친다. 부분곱의 개수를 줄이기 위하여 Booth encoder를 사용하였고, partial product(부분곱)의 덧셈시간을 줄이기 위하여 4:2 CSA(can save adder)와 3:2 CSA로 CSA tree를 구성 하였으며, 최종결과는 carry look- ahead tree로 얻어진다. Hyundai CMOS 0.35$\mu\textrm{m}$ 1-poly 4-metal 공정으로 layout하여 설계하였으며, 곱셈시간은 2.7ns(tipical case)이하로 측정되었다.

ATM networks with long-distance links, causing long propagation delays, may require virtual end system functions to provide ABR services. We survey several issues for implementing the control functions for ABR service in multiple VCs, required in the virtual ends, and propose a structure for implementation. In the proposed design, shared memory structure is used to control the cell emission of the multiple VCs for the ABR services in the virtual end systems.

In this paper we designed a simple 8-bit processor using HDL. The simple 13-bit processor has 19 instructions with three different addressing modes. The processor includes registers - IR, PC, SP, Y, MA, MD, AC, IN, OUT - and 256Kbyte memory. We examined the operation of the processor through simulation and then synthesized it on FPGA.

본 논문에서는 심도(Depth) 카메라로부터 실시간 획득한 RGBD 데이터에서 심도 정보 기반의 AAM(Active Appearance Models)과 나이 인식 알고리즘[1]을 통해 4 개의 AG(Age Group)으로 분류하는 실시간 얼굴 나이 인식 시스템(Real-time Facial Age Recognition System)을 설계한다. 기존의 AAM 을 이용한 실시간 얼굴 특징 추출은 평균 약 4.17%의 프레임 손실율을 보였으나, 심도 정보를 활용한 AAM 은 평균 약 0.43%의 프레임 손실율만을 보였다[5]. 본 논문에서는 심도 정보를 활용한 AAM과 병렬 처리 방법인 CUDA 를 결합하여 나이 특징을 추출하고, 실시간 시스템에 적용 가능하도록 나이 인식 알고리즘을 개선하여 실시간 나이 인식 시스템을 설계한다. 설계된 시스템은 1)머리 위치 추적, 2)얼굴 인식 및 특징점 추출, 3)나이 특징 추출, 4) 나이 특징 분석, 5) 나이 분류의 5 가지 단계를 통해 최종적으로 4 개의 AG 로 분류한다.
