In construction management the estimation procedure of construction expanses follows a series of submission phases: production of drawings, the assessment report, and the expanse report. In South Korea, it is a widely known issue that the expanse report only includes the net expanses at each construction phase and part, which makes it difficult to trace detailed basis from the records. This issue with inefficient record management should pose a number of problems, which result from discontinuation of construction record, unproductiveness for reproduction of records at each construction and submission phases for construction management, and failure to perform fair management among the contracting parties. Thus, the amendment in which the assessment report and the quantity estimation report reflect common codes to share throughout types of construction, space, and parts should be applied into practices so as to model production of acceptable reports and record.

MPEG II 비디오 스트림과 오디오 AC-3 스트림, 자막 스트림에 지역 코든 복제 방지 메뉴 등을 프로그램 하여 하나의 스트림으로 만들고, 시나리오에 따라 속성, 명령 및 작동을 부여하여 최종 디스크 이미지(DVD)를 만드는 과정을 오소링(Authoring)이라고 한다. 이러한 오소링(Authoring) 툴들은 다양하게 출시되어 있는데, 간단한 타이틀을 만드는 보급형부터 전문적인 영화 타이틀을 만드는 고급형까지 용도에 따라 선택하여 쓸 수 있다. 본 논문에서는 일반적인 IEEE 1394포트를 이용하여 영상과 음향을 컴퓨터로 캡처(Capture)해서 DVD를 만드는 오소링(Authoring) 과정을 일반인들이 Desktop PC로써 가장 많이 사용하고 있는 Window체계의 PC와 OSX 체계의 Macintosh를 중심으로 비교, 분석하고자 한다.

The color appearance of a yarn-dyed woven fabric depends on the color of the yarn as well as on the weave structure. Predicting the final color appearance or formulating the recipe is a difficult task, considering the interference of colored yarns and structure variations. In a modern fabric design process, the intended color appearance is attained through a digital color methodology based on numerous color data and color mixing recipes (i.e., color prediction models, accumulated in CAD systems). For successful color reproduction, accurate color prediction models should be devised and equipped for the systems. In this study, the final colors of yarn-dyed woven fabrics were predicted using six geometric-color mixing models (i.e., simple K/S model, log K/S model, D-G model, S-N model, modified S-N model, and W-O model). The color differences between the measured and the predicted colors were calculated to evaluate the accuracy of various color models used for different weave structures. The log K/S model, D-G model, and W-O model were found to be more accurate in color prediction of the woven fabrics used. Among these three models, the W-O model was found to be the best one as it gave the least color difference between the measured and the predicted colors.

This study was conducted to construct the soil bin system and associated microcomputer-based data acquisition system which is to be used for the effective evaluation of wheel performance. The soil bin system consists of four main parts; soil bin, carriage drive system, test carriage and soil processing carriage. The test carriage was constructed to measure the five performance parameters of testing wheels; pulling forte, motion resistance, sinkage and rotational speed of test wheel, and speed of test carriage. The test wheel is powered by a hydraulic system up to 8 ps. Soil processing carriage was designed to provide uniform test soil condition across the toil bin, and reproduction of soil conditions found satisfiable. The data acquisition system consists of APPLE II PLUS microcomputer, strain amplifier, I/O interface, A/D converter, digital counter and various transducers. It takes about 0.86 seconds to measure a set of performance parameters and store on the floppy disk simultaneously. Series of experiment showed that this system can be used effectively for evaluating the wheel performance associated with soil.

높은 동적 범위(HDR) 영상는 일반적인 표준 디지털 영상에서 허용하는 것보다 훨씬 높은 동적 범위를 처리하는 디지털 영상 처리 기법이다. 이러한 HDR 영상에 대한 사실적 디스플레이를 위한 톤 매핑이 많이 연구되고 있다. 그러나 화면 휘도 분석을 위한 HDR 영상의 과학적 시각화는 주목을 받지 못하고 있다. 본 논문에서는 HDR 영상에서 색상 정보의 재생과 시각화를 위한 접근 방법을 제시한다. 색상 시각화 함수들을 구현하고, HDR 영상의 일반적인 평가요소에 따라 시각화 효율성에 대해 평가한다.

Shaking tables are devices for testing structures or structural components models with a wide range of synthetic ground motions or real recorded earthquakes. They are essential tools in earthquake engineering research since they simulate the effects of the true inertial forces on the test specimens. The destructive earthquakes that occurred at the north part of Algeria during the period of 1954-2003 resulted in an initiative from the Algerian authorities for the construction of a shaking simulator at the National Earthquake Engineering Research Center, CGS. The acceleration tracking performance and specifically the inability of the earthquake simulator to accurately replicate the input signal can be considered as the main challenge during shaking table test. The objective of this study is to validate the uni-axial sinusoidal performances curves and to assess the accuracy and fidelity in signal reproduction using the advanced adaptive control techniques incorporated into the MTS Digital controller and software of the CGS shaking table. A set of shake table tests using harmonic and earthquake acceleration records as reference/commanded signals were performed for four test configurations: bare table, 60 t rigid mass and two 20 t elastic specimens with natural frequencies of 5 Hz and 10 Hz.

In the apparel industry, the technology has been advanced rapidly. The use of 3D scanning systems fur the capture and measurement of human body is becoming common place. Three dimensional digital image can be used for design, inspection, reproduction of physical objects. The purpose of this study is to develop a method that drafts men's basic bodice pattern from scanned 3D body surface shape data. In order to pursue this purpose the researchers developed pattern drafting algorithm. The 3D scanner used in this study was Cyberware Whole Body Scanner WB-4. The bodice pattern drafting algorithm from 3D body surface shape data developed in this study is as follows. First, convert geometric 3D body surface data to 3D polygonal mesh data. Second, develop algorithm to lay out 3D polygonal patches onto a plane using Auto Lisp program. The polygon meshes are coplanar, and the individual mesh is continuously in contact with next one The bodice front surface shape data in polygonal patches form was lined up in bust and waist levels. The back bodice was drafted by lining up the polygonal mesh in scapula, chest, and waist levels. in the drafts, gaps between polygons were formed into the darts.

디지털 워터마크 기법은 음악, 영상, 동영상에 대한 저작권과 재산권의 보호 및 인증, 데이터 손실 여부 판단, 복사 방지 및 추적 등을 목적으로 한 사후 재산권의 보호 기술로 제안되었다. 본 연구에서는 워터마크의 기하학적인 왜곡에 대한 공격에 견고하게 하도록 영상의 전 처리 과정을 거친다. 그리고 선택된 기하학적인 불변 점을 골라 여러가지 영상처리에 강인하며 일정 기간 압축 저장되는 영상에서도 워터마킹이 유지되도록 워터 쉐드(watershed) 분할 기법을 이용한 의료 영상 보안 알고리즘을 제안한다. 본 논문에서 제안한 워터마킹 알고리즘은 의료 영상에 대한 RST공격, JPEG 압축 공격 그리고 필터링 공격보다 강인함을 확인하였다.

본 논문은 가상현실(Virtual Reality)속 입체 공간에서 동양화 중 '산수화'를 표현할 수 있는 방법에 대해 연구한 결과이다. 그림 속으로 들어가 교감하며 감상하는 동양화의 특성과 가상현실이라는 매체가 가진 '몰입성'의 유사점을 중심으로 동양화의 대표적인 특징 세 가지(여백, 시점, 그림자)를 정리하고, 디지털 콘텐츠 속에서 구현하는 과정을 연구했다. 자연스러운 수묵기법의 표현을 위해 산, 나무 텍스쳐를 제작했고 콘텐츠 환경으로 여백, 그림자를 표현했으며, 동선 스토리텔링으로 시점을 재현했다. 단순히 동양화의 표현유형을 적용시킨 콘텐츠가 아닌, 체험자가 실시간으로 시점을 변환하며 감상 할 수 있는 차별화된 콘텐츠라는 점에 의의를 둔다.

Ryuseo(類書) is a type of traditional books and seems like today's encyclopedia. For compilation of this book, the contents with good ideas and the improvement in method of editing are very important. The process of development, basic form, reception and transformation, the method of succession in today were investigated with the traditional Ryuseo through this study. In Korea, the publishing of this book in the beginning was just republishing of Chinese Ryuseo. During the reign of king Sunjo of Chosun dynasty, Ryuseo for Korean, "Daedongeunbugunok(大東韻府群玉)" was published. Also the basic form of Ryuseo had to be changed in this period. Kimyuk increased practical use of this book by summarizing "Samunryuchui(事文類聚)". The first complete Korean Ryuseo was "Kosachalyo(故事撮要)" that was published in 1554, king Myungjong. In the book was included contents about diplomacy and daily life by Eosukkwun. In 1771, king Youngjo, "Kosashinseo(故事新書)" was published. It had more information about actual life than Kosachalyo. Ryuseo should be considered with two things when it is read by modern readers. One is the development of material for study and another is to ensure the readers. So Ryuseo could be a good basic material for developing contents of internet. Reproduction of this book by new one should be considered with increasing its function. Because reforming classical material by digital one is necessary for daily life in today.
