The purpose of this study is to draw the digital design curriculum in architectural design studio. For this study, works using digital design process in professional and academic projects were investigated. Digital design curriculum is consisted of 3 steps; fundamental, intensive and advanced courses. The fundamental course acquires capability for raising architectural thought through digital media. The intensive course acquires capability for raising architectural design process. Finally, the advanced course acquires capability for raising synthesis design works and professional abilities in architectural design. It is also a urgent need of unified roadmap about digital design curriculum for architectural design education in Korea.

Digital forensics refers to finding electronic evidences related to crimes. As cyber crimes are increasing daily, digital forensics for finding electronic evidences is also becoming important. At present, various aspects of digital forensics have being researched including the overall process model and analysis techniques such as network forensics, system forensics and database forensics for digital forensics. Regarding database forensics, only analysis techniques dependent on specific vendors have been suggested. And general process models and analysis techniques which can be used in various databases have not been studied. This paper proposes an integrated process model and analysis technique for database forensics. The proposed database forensics model (DFM) allows us to solve problems and analyze databases according to the situation and purpose, and to use a standard model and techniques for various database analyses. In order to test our model(DFM), we applied it to various database analyses. And we confirmed the results of our experiment that it can be applicable to acquisition in the scene as well as analysis of data relationships.

This study presents the plans to derive quality items for develop the data quality standard for ensuring the quality of 3D building geospatial data in NDT(National Digital Twin). This paper is organized as follows. The first section briefly examines various factors that impact the quality of 3D geospatial data, and proposes the role and necessity of the data quality standard as a means of addressing the data errors properly and also meeting the minimum requirements of stakeholders. The second section analyzes the relationship between the standards - building data model for NDT and ISO 19157: Geospatial data quality - in order to consider directly relevant standards. Finally, we suggest three plans on developing NDT data quality standard: (1) the scope for evaluating data quality, (2) additional quality elements(geometric integrity, geometric fidelity, positional accuracy and semantic classification accuracy), and (3) NDT data quality items model based on ISO 19157. The plans reveled through the study would contribute to establish a way for the national standard on NDT data quality as well as the other standards associated with NDT over the coming years.

잔향시간이 긴 실내의 전달함수의 모델링에 있어서 , 일반적인 플 밴드 MA 모델에 기초한 적응 필터를 이용한 경우에는, 많은 필터 차수를 필요로 하고 적응 시간이 길어지는 문제점이 있다. 본 논문에서는 필터 차수를 감소시키고 수렴 특성을 향사시키기 위해서, 각 입출력 신호를 몇 개의 주파수 대역으로 나우어서 각각의 주파수 대역에 대새서 적응 처리 과정을 행하는 서브밴드 MA 모델을 이용한 적응디지털 필터 처리 방법을 제안한다. 컴퓨터 시뮬레이션 서브밴드MA 모델을 이용한 디지털 적응 필터 처리과정의 유효성을 나타냈었다.

This is the study for system model of digital contents quality assurence. We develope a lot of digital contents which are games, mobile contents, e-learnning contents etc. The most of case that contents have to think about export to abord. Unfortunatly we still not to much think about digital contents quality. This paper propose the system model of digital contents quality assurence base on the process lifecycle for prepare international competation.

유비쿼터스 환경은 조직의 구조와 개인의 행위를 변화시킬 뿐만 아니라 기업의 경쟁 패러다임 자체를 변화시킬 것으로 전망하고 있다. 또한 유비쿼터스 컴퓨팅의 기술이 경영경제, 행정, 교육, 문화, 의료등 사회 전반에 걸쳐 도입되고 있으며, 이에 따른 비즈니스 모델에 대한 중요성이 증대되고 있다. 기술에 관련된 RFID, USN, 표준화, 보안등에 대한 연구가 활발히 이루어지고 있으나, 비즈니스 모델에 관련된 연구는 미흡한 실정이다. 본 연구에서는 유비쿼터스 컴퓨팅에 대해 알아보고 비즈니스 모델 사례 검토를 통해 유비쿼터스 컴퓨팅 시대의 비즈니스 모델과 발전 방향 및 혁신 전략을 제시하고자 한다.

This paper describes a study on the digital watermarking algorithm which is used to confirm the copyright protection of digital audio data. The digital audio watermarking algorithm based on psychoacoustic model is used for the inaudibility of the watermark data. The psychoacoustic model which is a key algorithm in MP3 audio compression is analyzed by MATLAB simulation, and is applied to digital audio watermark insertion.

본 논문에서는 불확실성을 포함할지도 모르는 비선형 시스템의 추적 제어에 효과적인 퍼지모델기반 제어기에 대한 지능형 디지털 재설계 기법을 제안한다. TS 퍼지모델은 불확실 비선형 시스템의 퍼지모델링에 적용되었다. 안정화와 추적을 위한 퍼지모델기반 제어기를 설계하기 위해 확장 병렬 분산 보상 기법이 이용되었다. 설계된 연속시간 제어기는 지능형 디지털 재설계 기법을 이용해 등가의 이산시간 제어기로 변환되었다. 본 논문에서 제안한 지능형 디지털 재설계방법은 전형적인 단일 링크 유연 로봇 시스템에 적용하여 그 응용 가능성과 효용성을 입증한다.

The purpose of this study is to present some basic information essential for planning long-term preservation of digital audio files, which have been collected through 'Cultural Archetypes Digitization Project' by the Korea Culture & Content Agency. Needs and limitations of digitization of audio resources for their long-term preservation, digital audio archiving models(OAIS Reference Model and AHDS Model), some technical principles for audio digitization and preservation, preservation metadata and storing media for digital audio files were discussed. Compliance to the requisites listed in Audit Checklist for the Certification of Trusted Digital Repositories of RLG & NARA was suggested. It was also recommended to review the appropriateness of collaborating on digital preservation project with other institutions.
