This study is a study on the building integrated method of Photovoltaic. It was analyzed into a basic installation condition and an integrated form in this study. And it was confirmed through the 3D simulation & drawing work of an integrated situation to the real domestic building. The Photovoltaic installation of the country to an optimal efficiency for the year must be installed to the due south with an angle of thirty degrees. And also a module spacing must be more than doubled from the bottom to the top of module to prevent from efficiency falling by a shadow of photovoltaic module in a roof setting of flat roof. If Photovoltaic module is an adequate material that is a basic requirement as a building's finishing material, it's not only an efficiency of alternation with an existing finishing material but also a building's design element.

High-Level Architecture(HLA)/Run-Time Infrastructure(RTI) are standards for distributed simulation systems and offer a technology to interconnect them and form one single simulation system. In defense domain, M&S is the only way to prove effectiveness of weapon systems except for Live Fire Testing (LFT). This paper focuses on guided missile simulations in weapon systems for engagement analyses and proposes the integrated flying vehicle model that is based on HLA/RTI. There are a lot of missiles in real world; therefore, we should develop each missile models in M&S in order to apply battlefield scenarios. To deal with the difficulties, in this paper, firstly, I classify these missiles into three models: ballastic, cruise, and surface-to-air missile models, and then I design each missile model and integrates them into a single model. This paper also offers a case study with my integrated flying vehicle model. At the conclusion, this paper presents contributions of this paper.

인터넷 서비스 가입자망은 다양한 멀티미디어 서비스를 제공하는 새로운 대안으로 제시되고 있는 망이지만 접속 방식에 따라서 여러 가지 형태와 특성을 가지고 있다. 접속 방식 별로 여러 가지의 이기종(異機種) 장비들이 배치되고 있으며, 전국적으로 분산된 가입자 망 장비 및 자원에 대한 효율적이며 집중적인 통합 관리를 위해서는 관리되는 장비의 종류에 무관한 일반적인 정보 모델인 단일화된 개념적/추상적 관리객체 모델이 요구된다. 본 논문은 인터넷 서비스 가입자망을 통합 관리하기 위한 추상적이며 논리적인 관리객체 모델을 제시하였다. 그리고 이를 기반으로 UML을 이용한 객체지향 방법론을 적용하여 가입자망인 DOCSIS 기반의 케이블데이터 서비스를 위한 가입자망과 VDSL서비스를 위한 가입자망에 대해 동일한 모델을 적용하여 하나의 통합된 가입자망을 관리할 수 있는 시스템을 설계하고 구현하였다.

This study is conducted with the aim of redefining the university-based lifelong education support system for developmental disabled. The research method consisted of procedures in parallel with literature analysis and expert meetings. As for the contents of the study, a composition system that recognized the problems and solutions of lifelong education for the developmental disabled based on universities was primarily presented. Through this, it was suggested that universities can form an academic foundation for the establishment of a lifelong education support system for the developmental disabled along with the convergence field. In addition, a structural model related to this was presented along with the aspect that universities could develop a curriculum for lifelong education for the developmental disabled according to the school foundation. Also, a composition system was suggested that universities can develop lifelong education curriculum for people with developmental disabilities to lead the cooperation of local related organizations such as welfare centers for the disabled and lifelong education centers for the developmentally disabled. As a result of the study, it was analyzed that leadership in the university-based lifelong education support system for developmental disabled can contribute to fostering professional manpower qualifications and establishing cooperation with local related organizations in an integrated composition system.

최근 웹 공격 기술의 발달로 인하여 기존 웹 로그 분석에 통한 공격 탐지 기술뿐만 아니라 웹 방화벽 로그, 웹 IDS 및 시스템 이벤트 로그 등과 같이 다수의 웹 관련 감사 자료를 이용하여 웹 시스템에 대한 공격 이벤트를 분석하고 비정상 행위를 탐지할 필요가 있다. 따라서 본 연구에서는 웹 서버에서 생성되는 IIS 웹 로그 정보와 웹 방화벽 및 웹 IDS 시스템에서 생성되는 이벤트 로그 정보 등을 이용하여 일차적으로 통합 로그를 생성하고 이를 이용하여 웹 공격을 탐지할 수 있는 시스템을 설계 및 구현하였다. 본 연구에서 제안한 시스템은 다중 웹 세션에 대한 분석 과정을 수행하고 웹 시스템 공격과 관련된 연관성을 분석하여 대용량의 웹 로그 및 웹 IDS/방화벽 정보를 대상으로 효율적 공격 탐지 기능을 제공하도록 하였다. 본 연구에서 제시한 시스템을 사용할 경우 능동적이고 효율적인 웹 로그 공격 이벤트 분석 및 웹 공격을 탐지할 수 있는 장점이 있다.

본 논문에서는 콘텐츠 적응화 서비스를 위해 필요한 프로파일들을 효율적으로 통합 관리 해주는 시스템을 제안한다. 콘텐츠 적응화 서비스 제공을 위해서 제안된 프로파일들은 다양한 서비스에서 이용되고 있다. 그러나 현재 프로파일들은 서비스에 따라 다르게 구성되기 때문에 상호 호환성이 부족하고 이로 인하여 통합 관리의 어려움을 가지고 있다. 또한 서비스 업체에 따라 별도로 프로파일을 운영함으로써 많은 운영비용을 소비하고 있다. 이와 같은 문제점을 해결하기 위해 다양한 종류의 프로파일을 통합하고 관리해주는 시스템이 필요하다. 제안된 프로파일 통합 관리 시스템은 프로파일 서비스 아키텍처와 기존 프로파일 연구를 기반으로 필요한 기능을 도출하였다. 프로파일 통합 관리 시스템은 CC/PP 명세를 준수하고 RDF 형태로 만들어진 프로파일을 지원하며, 프로파일 수신, 처리, 저장, 관리, 제공 기능 등을 지원한다. 또한 프로파일의 효율적인 운영을 위하여 메타데이터 구성 기법과 동적 기법을 적용하였다. 성능 평가 결과 프로파일 통합 관리 시스템에 제안된 기법들은 기존 기법에 비해 4% 향상된 결과를 나타냈다.

In this paper, we propose a fast code acquisition method that can reduce drastically the mean acquisition time of the direct sequence spread spectrum (DS-SS) system by using and integrated search and verification (ISV) scheme. The proposed method performs simultaneously the search and verification processes at every search cell, through storing sufficiently long signal samples enough to perform the verification process form the previously received samples. We analyze and acquisition performance in the case of Gaussian channel to evaluate theacquisition perfomrance of the proposed method. From the simple numericl analysis result, we have shown that the acquisition performance of the proposed method is better than that of the conventional serial search method, and the performance improvement becomes more prominent as the channel environment becomes degraded.

In designing and manufacturing a submarine, an expensive real mock up is usually built as a reference because of the spatial constraints of a submarine. This paper presents an integrated and automated design process for a submarine that uses a digital mock up. Various equipment libraries are built for feature based design. Using the developed digital mock up, this paper shows various ways to verify the design, including a space analysis to check for any interference between pieces of equipment and the hull and an ergonomic analysis using lifelike dummies to examine the work space and operability. As a part of the integrated design system, a design automation system was also developed to generate surface point data for the outer hull, pressure hull, casing, and sail. The whole process was applied to the design of a submarine for verification.
