오늘날 단백질 정보 분석은 HGP(Human Genome Project)이후 Post-genome 시대를 맞이하면서 매우 중요한 분야로 인식되고 있다. 이 단백질 정보를 이용하는 응용은 Discovery of Protein Structure/Function Relationships, Evolutionary Relationships, 3D Modeling 등 많은 분야에서 활용되어진다. 여러 가지 분야들 중에서 특히 단백질 구조 분석을 위한 많은 다양한 소프트웨어들이 출현되고 있다. 하지만 복잡하게 얽혀 있는 단백질들을 검증하기 위해서 Mass Spectrometry에서 발생되는 Peptide Masses의 정보들을 이용할 수 있다. 이에 본 논문에서는 Mass Spectrometry에서 생성된 Peptide Mass Map을 이용하여 기존의 단백질 Database에 있는 단백질들과 비교하는 자동화 단백질 검증 시스템 설계 및 구현에 관한 연구내용을 담고 있다. 이 시스템은 3-계층 중심으로 개발이 이루어지며 이 기종 시스템과의 원활한 통신 다중 계층의 환경에 있는 각 객체들간에 통신을 위해서 RMI 기반의 미들 웨어를 활용하기로 한다.

A method for mapping quantitative trait loci (QTL) was introduced incorporating the information of mixed progeny from complex pedigrees. The method consisted of two steps based on single marker analysis. The first step was to examine the marker-trait association with a mixed model considering common environmental effect and reversed QTL-marker linkage phase. The second step was to estimate QTL effects by a weighted least square analysis. A simulation study indicated that the method incorporating mixed progeny from multiple generations improved the accuracy of QTL detection. The influence of within-genotype variance and recombination rate on QTL analysis was further examined. Detecting a QTL with a large within-genotype variance was more difficult than with a small within-genotype variance. Most of the significant marker-QTL association was detectable when the recombination rate was less than 15%.

Design factors are very important and deterministic in determining the first impression of products and environment. The final 30 number of channel button were chosen as a design factors at the Audio Unit. Then, we made the 8 types of prototype. with combining the design factors for experiment. Subjects rated the SD(Semantic Differential) evaluation sheets which have the 30 adjectives after watching each prototype. With the evaluated values, we simulated to identify the relation between the design factors and the adjectives using Neural Network. As a results, we could abstract the affective adjectives on each 8 types. Therefore, this research suggested the possibilities that we can infer the optimal design factors and types using Neural Network, if adjectives were given.

Not all line or point features capable of being extracted by sonar sensors from cluttered home environments are useful for simultaneous localization and mapping (SLAM) due to their ambiguity because it is difficult to determine the correspondence of line or point features with previously registered feature. Confused line and point features in cluttered environments leads to poor SLAM performance. We introduce a sonar feature structure suitable for a cluttered environment and the extended Kalman filter (EKF)-based SLAM scheme. The reliable line feature is expressed by its end points and engaged togather in EKF SLAM to overcome the geometric limits and maintain the map consistency. Experimental results demonstrate the validity and robustness of the proposed method.

In this thesis, we analysed urban fires and developed the predictive mapping technique by using GIS and spatial statistics. It presented the correlation between the fire data of last 5 years ($2001{\sim}2005$) and the factor of civilization environment in Daegu city. We produced a model of fire hazard predictive map by analyzing uncertainty of fire with the quadrat analysis and the poisson distribution.

온톨로지 기반 분산 정보시스템 환경에서는 시스템들 간의 정보 공유을 위해 전문가에 의한 명시적 온톨로지 매핑(Explicit Mapping)을 통해 의미적 이질성(Semantic Heterogeneity)을 해결하고 있다. 하지만, 온톨로지 매핑의 고비용성 때문에 모든 정보시스템들 간의 매핑이 이루어지기 힘들다. 따라서, 본 논문에서는 이미 존재하는 온톨로지 매핑 정보들의 재사용을 통해 존재하지 않은 온톨로지 매핑 정보를 묵시적으로 예측하고자 한다. 본 논문에서는 이와 같은 분산 환경에서의 쿼리 전송을 통한 지식 검색에 있어서의 온톨로지 매핑을 기반으로 한 적절한 쿼리 변환 방법론을 소개하고자 한다.

This study proposes an effective algorithm that can simulate a lighting environment, especially an LED backlight unit, using the photon mapping method. For higher reliable simulation, we modeled spectral and optical characteristics of LEDs, light sources, and optical sheets. From rendered images, we confirmed that the proposed algorithm can effectively simulate the lighting distribution of LED backlight unit.

Multimedia interpretation describes a high level of ion of multimedia content like interrelations and coherencies. In this paper, we describe a multimedia interpretation component from human-centered perspective. In this context, we see the role of the multimedia interpretation component as a liaison between the psychological apparatuses and computer-based artifact. We emphasize this role of multimedia interpretation by outlining a mapping process of the psychological apparatuses and computer-based artifact. This mapping process needs to be transparent to its user so that effective human-centered systems can be achieved. This transparency will provide an immersive environment for the users and enable uninhibited interaction between the users and the artifact. Furthermore, we illustrate how the multimedia interpretation component can be utilized in the medical diagnosis and treatment support application.

Recently, various robots are being used for the purpose of structural inspection or safety diagnosis, and their needs are also rising rapidly. Among the structural inspection using robots, a lot of researches has recently been conducted on inspection of various facilities and structures using an unmanned aerial vehicle (UAV). However, since GNSS (Global Navigation Satellite System) signals cannot be received in an environment near or below structures, the operation of UAVs has been done manually. For a stable autonomous flight without GNSS signals, additional technologies are required. This paper proposes the autonomous flight system for structural inspection consisting of simultaneous localization and mapping (SLAM), path planning, and controls. The experiments were conducted on an actual large bridge to verify the feasibility of the system, and especially the performance of the proposed SLAM algorithm was compared through comparative analysis with the state-of-the-art algorithms.

In this paper, we designed, implemented, and verified the SLAM system that can be used on mobile devices. Mobile SLAM is composed of a stand-alone type that directly performs SLAM operation on a mobile device, and a mapping server type that additionally configures a mapping server based on FastAPI to perform SLAM operation on the server and transmits data for map visualization to a mobile device. The mobile SLAM system proposed in this paper is to mix the two types in order to make SLAM operation and map generation more efficient. The stand-alone type SLAM system was configured as an Android app by porting the OpenVSLAM library to the Unity engine, and the map generation and performance were evaluated on desktop PCs and mobile devices. The mobile SLAM system in this paper is an open source project, so it is expected to help develop AR contents based on SLAM in a mobile environment.
