90년대 이후 새로운 소프트웨어 개발 방법론으로 객체 지향 방법론이 새로운 패러다임으로 등장한 후 최근에는 컴포넌트 기반 개발 방법 등이 소개되어 다양한 분산 컴포넌트 기술이 태동되었다. 분산 컴퓨팅 환경 하에서의 컴포넌트 기술은 정보 시스템 구축 시 구성요소의 모듈화를 용이하게 하고 인터페이스를 통한 컴포넌트 재사용 성을 가능하게 하여 소프트웨어 생산성 향상에 크게 기여하였다. 본 연구에서는 OMG에 의해 제안된 표준 분산모델로서 코바 프레임워크를 기반으로 정보구조 모델링 방법론을 이용하여 컴포넌트를 구성하고 컴포넌트의 추출을 돕기 위한 컴포넌트 저장소 명세서, 분산 어플리케이션 개발 프로세스 절차를 제안 하고자 한다.

This paper proposes a structure based on a production method of concept art focused on the player's experience through a module by using the game aesthetics of the MDA framework. And also a partially automated process established in concept art production by using the 'Adobe Color image color extraction' as a tool in the work production process. This paper proposed a work process of not just a personal expression but a systematic molding expression to use, and this could see as the various possibilities of game concept art productions.

프로세스의 소형화 및 집적화 와 임베디드 운영체제의 발달은 PDA, 세룰러폰 둥의 이동 기기의 이용을 대중화 시켰고 공간적 제약성의 극복을 가능하게 하였다. 이러한 기반 인프라의 확산은 가상환경 내에서 존재하던 서비스들을 사용자의 공간에서도 사용가능하게 함으로써, 컴퓨팅 환경이 더 이상 컴퓨터 중심이 아니라 사용자의 편리성을 극대화 시키는 사용자 중심의 패러다임의 전환을 의미하고, 이를 유비쿼터스 컴퓨팅으로 정의한다. 여기서 주목해야 할 것은 이러한 편리한 인프라들의 신뢰성 및 안전의 보장이다. 인터넷 뱅킹이나 모바일 비즈니스 등의 작업 수행에서 개인이나 기관의 기밀 정보의 유출이나 해킹으로 인한 문제점들은 이미 드러난 상태이며, 기존의 보안 서비스로는 유동적이고 사용자에 따라 변화가 많은 유비쿼터스 환경의 효율적 관리가 힘들다는 사실을 보여 주고 있다. 본 논문에서는 이러한 점을 고려하여 사용자의 주변 요소들을 반영이 가능하도록 정책과 기능성을 구분하여 설계된 계층적 보안 모델을 기반으로, 효율적인 건한 접근 관리를 위해 설계된 사용자 역할 기반의 권한 프로토콜을 제시한다. 이는 유비쿼터스 환경의 특징을 고려하여 유연성 과 확장성의 특징을 갖는다. 이를 기반으로 이동 디바이스와 데스크 탑 간의 신뢰성 있는 서비스 이용을 고려하여 디자인한 보안 모듈 제시한다.

It had been longer that the design mock-up was made mainly in order to test products. These days, it seems to be main stream that the working mockup is done because designers consider not only the design but also usability. In this study, the modular hardware toolkit, complimentary with Adobe Flash, was developed so that it solves the problem, the electronic hardware which the designers should struggle to make by themselves. This result thing could help the time of the design process to be short and contribute to make robust system rapidly.

A variety of services for mobile payments by the activation of FinTech have been developed. Various payment methods were developed, and an authentication method was developed to improve the reliability of the payment. On the other hand, when mobile easy payment services are used, they have weak security because the authentication by phone number. Therefore, this paper proposes a technique for increasing the reliability of the authentication process using the unique device ID of the mobile device to improve the authentication process based on the telephone number. The core research contents are the architecture and process for the authentication of mobile payments based on the mobile device ID. The mobile payment architecture consists of a mobile device, authentication service, and mobile payment application. The mobile device consists of mobile device ID and phone number, and the authentication server consists of authentication module and encryption module. The mobile payment service consists of a pre-authentication module and decryption module. The process of mobile payment service is processed by the encrypted authentication information (device ID, phone number, and authentication number) among mobile devices, authentication server, and mobile payment application. The mobile device sends the telephone number and the device ID to the authentication server and the authentication server authenticates the user through an authentication process and encryption process. The mobile payment application performs the pre-authentication process by decrypting the received authentication number. This paper reports a difference that can prevent the risk of leakage of the authentication number in existing payment services through the authentication process of the authentication server and the pre-authentication process of the mobile payment service of this paper.

The Test and Evaluation (T&E) system became more important due to its advancement and complexity of the weapon system. Time and cost saving T&E related studies are in progress mainly with advanced countries. By utilizing the Modeling and Simulation (M&S) technology recently, we may save time and money. Also, overcome security and safety limitations. There are many M&S based research activities in South Korea but it is way behind of the system that some countries already have developed. i.e.; United States. This area of study requires new way of developing strategies in the T&E system of Korea. This study is to design the Operational T&E system for weapon systems based on modeling of processes. And we modeled the processes of operational performance evaluation through utilizing resources and performance modules of weapon systems and combined it with the simulation engine for 3D visualization. Through this, we propose the Operational T&E system for weapon systems based on modeling of processes that represent operational performances visually.

Mass Customization combines the advantages of mass production and customization. Mass customization has been praised as an innovative approach that would result in changes in business paradigm. However, there is no consensus on the concept of mass customization, but only a generally accepted framework exists to explain successful practices. Prior cases in mass customization are those of the small-medium sized or Internet-based companies. We in this paper explore the mass customization cases of market-leading manufacturers. Although those traditional organizations may be not for swift change, the cases of those companies are important because they target mass markets. Lampel and Mintzberg[35] proposed a continuum of strategies ranging from pure standardization to pure customization. This study investigates mass customization strategies of three companies. In this paper, the cases of cosmetics and sports shoe can be described as tailored customization, and the household appliances case can be classified as customized standardization. These three cases are compared with each other from the customers' decoupling point. Findings and implications of this research are discussed.

In intra-process isolation, file descriptors work as another attack vector from the memory corruption attacks. The attacker can read or write by corrupting file descriptors so they can escape the isolation. In this paper, we propose new lightweight capability-based access control system on file descriptor using ARM's hardware extension, PA(Pointer Authentication). Our system was implemented on Linux kernel module, only shows 5% overhead to control the access on the file descriptor.

This paper focuses on the development of a supporting S/W tool for the automated design of an automotive press trim die. To define the die design process based on automation, we analyze the press die design process of the current industry and group repetitive works in the 3D modeling process. The proposed system consists of two modules, namely the template models of the trim steel parts and UI function for their auto-positioning. Four kinds of template models are developed to adapt to various situations and the rules of the interaction formula which are used for checking and correcting the directions of the datum point, datum curve, datum plane are implemented to eliminate errors. The system was developed using CATIA Knowledgeware, CAA(CATIA SDK) and Visual C++, in order for it to function as a plug-in module of CATIA V5, which is one of the major 3D CAD systems in the manufacturing industry. The developed system was tested by applying it to various panels of current automobiles and the results showed that it reduces the time-cost by 74% compared to the traditional method.
