The structural design process of the buildings consists of several design phases, which perform the simple calculation and the decision mailing to be with designers judgement, recursively. In this paper, the information that created during the design phases and used for generating the rational design result is called intermediate information. The intermediate information as well as the structural design results must be managed together in order to develop an integrated system for computer aided structural design. This paper presents the research for the object modeling concepts and the formal object model according to them for the systematic management of not only structural design results but also intermediate information.

In the present paper we propose a new method of intermediate view reconstruction between stereo images using belief propagation_based stereo matching. Intermediate view reconstruction is an important step for multiview 3D display. Many previous paper about intermediate view reconstruction using depth information to synthesize interview though stereo matching were proposed. But depth information is different to estimated accurately. In the present paper, in order to obtain accurate depth information, belief propagation_based stereo matching was used.

PARO, a power-aware routing optimization mechanism, is proposed in [1] to minimize the transmission power needed to forward packets between wireless devices in ad hoc network. The mechanism works by redirecting the route to pass through one or more intermediate nodes on behalf on source-destination pairs, then reducing the end-to-end transmission power. This paper will show an extension of this model and provide an analysis of the geometrical area lying between source and destination in which the intermediate node elects to perform redirection. The duration the intermediate node stays in that area is also computed.

This paper presents the effects of depth map quantization for multiview intermediate image generation using depth image-based rendering (DIBR). DIBR synthesizes multiple virtual views of a 3D scene from a 2D image and its associated depth map. However, it needs precise depth information in order to generate reliable and accurate intermediate view images for use in multiview 3D display systems. Previous work has extensively studied the pre-processing of the depth map, but little is known about depth map quantization. In this paper, we conduct an experiment to estimate the depth map quantization that affords acceptable image quality to generate DIBR-based multiview intermediate images. The experiment uses computer-generated 3D scenes, in which the multiview images captured directly from the scene are compared to the multiview intermediate images constructed by DIBR with a number of quantized depth maps. The results showed that there was no significant effect on depth map quantization from 16-bit to 7-bit (and more specifically 96-scale) on DIBR. Hence, a depth map above 7-bit is needed to maintain sufficient image quality for a DIBR-based multiview 3D system.

최근 안경을 쓰지 않고 3차원 입체 영상을 볼 수 있는 무안경식 3차원 디스플레이 중에서 DIBR(Depth-Image-Based Rendering) 기반의 중간 영상을 생성하는 연구가 많이 진행되고 있다. DIBR 기반의 중간 영상 생성 방법은 정확한 깊이 정보를 요구하기 때문에 기존의 연구에서는 고가의 깊이 카메라를 활용하였다. 본 연구에서는 마이크로소프트사의 키넥트 센서를 이용한 실사 영상과 깊이 영상을 기반으로 다시점 중간 영상을 생성할 수 있는 시뮬레이션 프로그램을 개발하였다. 이 시뮬레이션은 키넥트(Kinect)를 활용한 저해상도의 깊이 영상으로부터 자연스러운 다시점 영상을 획득하는 것을 목적으로 하며, 이를 위해 생성된 영상의 품질을 평가할 수 있는 기능을 통합적으로 제공한다. 본 논문에서는 이러한 시뮬레이션 프로그램의 시스템 구조와 구현에 대해서 설명한다.

본 연구는 에너지 및 환경경제학에서 기초 데이터로 많이 활용되는 산업연관표에서 특정 부문이 하부 부문들로 분리되는 경우 새로운 산업연관표를 추계하는 과정을 제시하였다. 보편적으로 산업연관표 추계에 이용되는 RAS 방법은 새로운 산업연관표의 부문별 생산액, 중간투입계, 중간수요계의 정보를 반드시 필요로 하지만, 많은 경우에 부문별 중간수요계 정보를 확보하기 어렵다는 문제가 있다. 본 연구는 특정 부문이 하부 부문들로 분리되는 상황에서 부문별 중간수요계 정보를 사용하지 않고도 새로운 산업연관표를 추계할 수 있는 과정을 제시하였다. 핵심 아이디어는 분리 후 산업연관표의 많은 원소들의 값이 분리 전 산업연관표의 원소들 값과 같다는 점과 분리 후 부문들의 원소 합이 분리 전 부문의 원소 값과 같다는 점이다. 중간수요계 정보 대신에 이들 정보를 이용해서 부문 분리 후의 산업연관표에 대한 중간거래행렬이나 투입계수행렬을 추계하는 과정을 제시하였다. 소규모 시뮬레이션 결과, 본 연구가 제시한 과정은 투입계수행렬의 경우 평균 약 11.23%의 추정 오차를 가지며 이것은 중간수요계 정보를 활용하는 RAS의 11.30%의 평균 추정 오차보다 작은 것으로 나타났다. 그러나 여러 선행연구들에서 추가 정보를 활용하는 것이 활용하지 않는 것보다 추정 성과를 항상 향상시키지 않는 것으로 나타났기 때문에, 본 연구의 방법을 현실에 적용하기 위해서는 다양한 시뮬레이션 연구가 필요하다고 판단된다.

In this paper, we present an algorithm for synthesizing intermediate views from a stereoscopic pair of images. Syntheses of intermediate images allows one to realize a more comfortable the 3D display system. The proposed method is based on block matching, which is not ordinarily used. The contour information is used for a block decision. In order to find an equivalent (or corresponding) block, there are two steps: "matching of contour-to-original image" and "matching of contour-to-contour image" methods. "Matching of contour-to-contour image" uses both left and right contour images. This block matching method allows us to find the corresponding block in spite of different block sizes. Experimental results illustrate the performance of the proposed technique and we obtained a high quality image of more than 31 dB PSNR.image of more than 31 dB PSNR.

The revitalization of e-business via Internet brings big changes to the postal business, and leads to a tremendous increase of heavy and large sized postal mails with continuing growth of home delivery business. Thus, even though the number of intermediate storages for mail delivery that mailmen use for picking up mails in the middle of mail delivery has been being increased, it has still many problems such as insufficient number and size of the storages as well as avoidance of mail keeping of trust agents. It is necessary that safety of mail keeping, seamless mail delivery, and individual parcel pick-up process reestablishment should be made through an improved counter plan for the problems described previously. This study presents the efficient and right operational plan for the intermediate storage for mail delivery with providing the number and size of intermediate storages per mail delivery sequence according to four different types of post offices.
