소프트웨어 프로덕트 라인 공학은 공통성과 가변성 식별을 통해 소프트웨어 재사용을 극대화 시키는 접근방법으로 이를 지원하는 도구에 대한 연구가 다수 진행되고 있다. 하지만 기존의 도구는 특성 다이어그램만을 지원하고 있고, 특성구성 정보를 이용한 프로덕트의 조립을 수행하지 못하고 있다. 따라서 본 연구에서는 소프트웨어 개발자에게 공통적 언어인 UML을 이용하여 특성모델을 표현하고 특성구성에 따라 조립을 수행하는 특성모델링 지원도구를 제안한다. 이러한 UML 기반의 특성모델링 지원도구를 통하여 보다 쉽게 특성모델링과 프로덕트 조립을 수행할 수 있다.

최근 많은 건축가들이 파라메트릭 디자인 도구에 관심을 가지고 형태에 대한 다양한 실험을 하고 있는 것과는 달리, 구조 엔지니어들은 이에 적절하게 대응하지 못하고 있다. 현재 파라메트릭 모델과 구조해석 프로그램사이의 자료교환을 가능하게 하는 인터페이스가 없는 것이 주된 원인이다. 따라서 구조 엔지니어들도 자유롭게 파라메트릭 방법론의 장점을 활용한 모델을 생성하고, 그것을 구조해석에 바로 사용할 수 있도록 하는 일이 오늘날 구조계가 당면한 과제이다. 본 연구에서는 파라메트릭 모델로부터 구조해석 모델을 자동으로 생성하는 인터페이스의 실무 적용가능성을 살펴보기 위하여, 파라메트릭 디자인 도구의 특성과 확장성을 검토하고, 라이노를 기반으로 하는 구조해석 모델 생성 플러그인을 개발하였다.

SMIL(Synchronized Multimedia Integration Language)은 멀티미디어 객체들의 시간적, 공간적 배열이 가능한 XML기반의 언어로서 웹브라우저상에서 효과적인 멀티미디어 표현을 가능하게 한다. 기존의 교육시스템에서는 멀티미디어컨텐츠의 동기화표현이 불가능하거나 별도의 클라이언트 어플리케이션이 필요하다. 본 논문에서는 멀티미디어 통합 언어인 SMIL의 메타모델을 분석하고 적용한 교육컨텐츠의 개발을 제안하고, 별도의 플러그인이나 어플리케이션이 필요없이 브라우저상에서 표현가능한 멀티미디어 교육컨텐츠를 설계하였다.

Garment modeling and simulation is now one of the important elements in broad range of digital contents. Though there have been recent products on garment simulation, general users do not know well enough how to design a virtual costume that meets some requirements about its specific clothing pattern. In particular, Hanbok - the Korean traditional costume - has many different characteristics against western ones in the aspect of its pattern design and of draping. This paper presents a knowledge-driven approach for virtual Hanbok modeling without knowing how to make real Hanbok. First, parameterized knowledge for several fabric types art solicited using visual similarity assessment from simulated and real cloth. Secondly, based on the analysis of designer's knowledge, we defined multi-level adjustment processes of Hanbok measurements with regard to body shape features for different virtual actors. An experimental system is developed as the form of a Maya plug-in and the result shows the applicability of the proposed method.

Existing tools using in the standard e-learning contents authoring were used a method to provide users contents template produced in advance. In order to use resources of the template in a common web-based authoring tool, there is problem to overcome. If the resource of template is inserted within the contents on the authoring tool, the deformation of the template by the user's input that may occur during the edit process cannot be controlled. In this paper, we propose an effective maintenance method to prevent deformation of the resource of template inserted into any WYSIWYG-based HTML authoring tool by user's discretion. We added a template plug-in that can create the IMS-QTI standard resource in tynyMCE the web-based open source editor of representative examples. And the plug-in for tinyMCE was realized as a module of directly respond to the action of limited user input. So, in response to the action of user's input, the structure of the template can be sustained possibly.

To solve big problem in high energy physics or bioinformatics, it needs a large number of computing resources. But it hard to be provided by one grid environment. While user can submit each job by using it's own user interface in each grid environment, it may need many cost and efforts to manage several hundred jobs conserved in each grid environment separately. In this paper, to solve this problem we develop Ganga's Gridway backend and InterGrid backend. Therefore as we provide the same grid user interface between different grid environments. We developed a Gridway backend module that provide users with access to globus-based grid resources as well. We have also developed an InterGrid backend that allows users to submit jobs that have access to both glite-based resources and globus-based resources. In order to demonstrate the practicality of the new backend plugin modules, we have integrated the AutoDock application used by WISDOM project into Ganga as a new built-in application plugin for Ganga. And we preformed interoperability experiment between PRAGMA grid based on Globus and EGEE grid based on gLite.

After the end of the service of Internet Explorer, the use of ActiveX ended, and the Non-ActiveX policy spread. HTML5 is used as a standard protocol for web pages established based on the Non-ActiveX policy. HTML5, developed in the W3C(World Wide Web Consortium), provides a better web application experience through API, with various elements and properties added to the browser without plug-in. However, new security vulnerabilities have been discovered from newly added technologies, and these vulnerabilities have widened the scope of attacks. There is a lack of research to find possible security vulnerabilities in HTML5-applied websites. This paper proposes a model for detecting tags and attributes with web vulnerabilities by detecting and analyzing security vulnerabilities in web pages of public institutions where plug-ins have been removed within the last five years. If the proposed model is applied to the web page, it can analyze the compliance and vulnerabilities of the web page to date even after the plug-in is removed, providing reliable web services. And it is expected to help prevent financial and physical problems caused by hacking damage.

몰입도가 높은 가시화 기법 중 하나인 입체 영상은 차세대 미디어의 표준으로 최근 크게 주목 받고 있다. 그러나 일반 2차원 영상과는 달리 입체 영상은 3차원의 기하정보가 존재해야만 영상을 생성하는 것이 가능하다. 따라서 3차원의 기하정보가 존재하지 않는 2차원 영상을 이용한 입체 영상의 저작은 매우 어려운 문제이다. 본 논문은 영상 기반 모델링 기법을 활용하여 단안 영상으로부터 입체 영상을 생성하기 위한 입체 영상 저작 도구를 제안한다. 이를 위해 입력된 영상에서 사영 기하 정보를 사용하여 깊이 정보를 추론함으로써 3차원 환경을 구성하는 전역 깊이 정보 추출 방법과 영상 내에 존재하는 사물의 정확한 깊이 정보로 수정하기 위한 부분 깊이 정보 수정 방법을 제안한다. 또한, 추출한 깊이 정보로부터 몰입감이 높은 입체 영상의 시점을 결정하기 위한 대화식 입체 영상 미리 보기 기능을 제안한다. 본 논문에서 제안한 기법은 2차원 영상 저작 도구인 포토샵의 플러그인으로 구현함으로써 범용성을 높였다.

In this paper, we propose a keyboard security method that is based on a subclassing. This method doesn't need an additional hardware and can be applied to Web browsers that do not support ActiveX controls. As the users of Web browsers such as Firefox, Safari, Chrome etc. are increased, it is more required to have the keyboard security methods that are based on software and don't use ActiveX controls. Thus we developed the user mode keyboard security method that is based on a subclassing with plugins. Our method doesn't need an additional hardware module and is interoperable with general kernel mode security programs.

In this paper, component sizing and analysis of the novel plug-in hybrid electric vehicle powertrain configuration is conducted. Newly proposed powertrain configuration in prior study has an internal combustion engine and two electric motors. To optimize component size of the vehicle system and reduction gear ratio, component sizing methodology is proposed and conducted. Required power for vehicle's dynamic performance is calculated to decide minimum power requirement of powertrain component combination. Component size of engine and electric motor are optimized using vehicle simulation to maximize fuel economy performance. Optimized powertrain configuration and vehicle simulation results present validation of newly proposed vehicle system.
