CAD (Computer-Aided Design) 시스템은 보다 정확한 공학적 분석과 보다 많은 설계 대안을 고려하므로 설계의 질을 증가시킨다. 이러한 과정 중에 수행되는 최적화에는 다양한 탐색 기법들이 사용되고 있다. 그레이팅 설계를 자동화하는 AutoCAD 기반 시스템인 GDS(Grating automatic Drawing System)에서도 다양한 탐색 기법들이 최적화를 위해 사용되고 있다. 실제 그레이팅의 설계 공정에 있어서, 그레이팅은 특정 제약 조건과 우선순위에 맞추어 배치되어야한다. 그러나 현 GDS는 이러한 조건을 만족하는 최적 해를 찾는 것을 보장하지 않는다. 그러므로 본 논문에서는 그레이팅 배치에서 준수해야할 제약 조건과 우선순위를 만족하는 최적 해를 찾기 위한 하용 가능한 $A^{*}$ 알고리즘을 GDS에 적용하며, 시뮬레이션을 통하여 균등 비용 탐색과 상대적인 효율성을 평가한다.

현재 웹 서비스에서 사용하고 있는 키워드 기반 검색은 syntactic한 정보만을 제공한다. 웹 서비스의 이러한 단점을 보안하고자 시멘틱 웹 기술이 제안되고 있다. DQL 검색 시스템은 검색 결과의 질을 향상시키기 위해서 시멘틱 웹 기반의 검색 시스템 중지 하나다. 시멘틱 검색은 입력된 질의들을 통해서 사용자가 원하는 정보와 의미가 일치하는 결과를 얻어내는 것이다. 본 논문은 시스템을 이용하는 각 사용자에 따라 검색되는 결과들에 우선순위를 적용하는 DQL 검색 시스템을 제안하고 다음 3가지 부분에 중점을 두어 시스템을 설계하였다. 첫째, 각 사용자들의 성향을 검색 결과에 반영하기 위해 개인화 프로파일과 온톨로지를 생성하는 개인화 온톨로지 생성기를 설계한다. 둘째. 검색 정확도틀 논이기 위해 검색 대상에 되는 정보들의 숙성과 관계를 추론해주는 검색 엔진을 설계한다. 마지막으로 DQL 검색 시스템의 사용 효율성을 높이기 위해 사용자가 입력한 키워드를 DQL로 자동 변환하는 DQL 컨버터를 설계한다.

This paper proposes a design for testability (DFT) and testability analysis method for register-transfer level (RTL) circuits. The proposed method executes testability analysis - controllability and observability - on the RTL circuit and determines the insertion points to enhance the testability. Then with the associated priority based on the testability, we insert only a few of the test multiplexers resulting in minimized area overhead. Experimental results shows a higher fault coverage and a shorter test generation time than the scan method. Also, the proposed method takes a shorter test application time required.

This paper is focused on the medical CRM system design for a hospital custom management. CRM systems provides information and seminars to whom are necessity. For this, priority retrieval and similarity retrieval are able to be in the personnel order and the regional. The customer receives the message which sends out from the hospital, The hospital manages the message which reveals a participation intention in the seminar at real-time. The hospital grasps the participation degree of the seminar where the customer will participate and manages the patients who participate to the seminar actively, and when the next seminar will be hold, we designed the system able to provide the service as early as possible.

Bridge structures are properly designed in accordance with the design specifications with required safety margin. However, due to the heavy vehicle traffic and environmental attacks, bridge often requires repairs and the deteriorated one should be replaced or rehabilitated. In this paper, a prior ranking algorithm is proposed to assist a decision making process in bridge management at network level. Based on the literature survey for the existing studuies, two important factors which affect the decision making procedure for bridge management at network level are identified. These factors are implemented into the algorithm as a load carrying capacity function and traffic function, respectively.

Traditional Pub/Sub(Publish/Subscribe) Systems search all subscriptions that match an incoming event by broker(i.e. it is not considering the accuracy of matching between an incoming event and subscriptions and only consider that an event either matches a subscription or not). However, subscriptions that match an event may have priority, therefore, we need priority Pub/Sub system. In this paper, we define what the accuracy means in order to prioritize among subscriptions and propose the Priority Retrieval Technique based on accuracy that able to search subscriptions. The Priority Retrieval Technique is based on IS-Lists. We can search the results ordered by accuracy.

The various services that a broadband integrated services digital network (B-ISDN) carries, have a wide range of delay, delay jitter and cell loss probability requirements. Design of appropriate control schemes for B-ISDN is an extremely important and challenging problem. In this paper, we proposed multiplexing algorithm with both delay and loss priorities in order to satisfy the diverse requirements. For the implementation of cell lose priority, we assumed that voice cells are generated as non-discardable(i.e., high priority) and discardable (i.e., low priotity)cells. The low priority voice cell may be discarded inside the network if congestion occurs. The cell dropping scheme is shown to reduce cell losses as well as delays for both voice and data. Such a load shedding scheme is expected to improve significantly utilization of B-ISDN.

This paper proposes a standard method for linking data between the U-City Integrated Urban Management Platform and u-service systems through systemization of event identification and standardization of event priority. By applying the proposed method, the incoming events to the Management Platform are listed and processed according to their priority of urgency. The application of the systemized event ID and standardized event priority enables prompt counter-measures against urban emergencies and disasters, which improves the efficiency of business processes by reducing the time and cost to complete required actions.

The format of game play varies depending on the priority of game design components by genre. In this study, in order to quantitatively derive the priority of game design components by genre, 6 game design components and 6 genres were extracted through prior research on game design components and genres, and then the research model was designed, and priorities were derived through AHP. Feedback system in action games, story in adventure games, mechanics in role-playing games, mechanics in simulation games, feedback system in table games, and mechanics in puzzle games were highly prioritized.

최근 HTML5, AJAX(Asynchronous JavaScript XML) 등으로 구현된 웹 애플리케이션이 널리 이용됨에 따라 웹 애플리케이션에 존재하는 취약점을 악용하는 공격 사례가 증가하고 있다. 웹 애플리케이션의 안전한 개발과 유지보수를 위해, 설계/구현 단계에서의 취약점 완화를 통한 예방, 그리고 운영 단계에서의 공격 탐지 및 대응이 필요하다. 더불어, 위험한 취약점들 및 공격 패턴들을 분석하고 우선순위를 부여하여, 웹 애플리케이션 개발 단계 및 운영 단계에서 심각한 취약점과 공격들을 우선 고려해야 한다. 본 논문에서는 OWASP Top 10과 CWE(Common Weakness Enumeration)를 연동시켜 CAPEC(Common Attack Pattern Enumeration and Classification)에서 웹 관련 주요 공격 패턴을 선별하고 순위화하였다. CWE는 취약점 예방에 도움을 주며, 순위화된 공격 패턴은 웹 애플리케이션에서 주요 공격들을 효율적으로 방어할 수 있게 하여 준다.
