Real-time(RT) object-oriented(00) distributed computing is a form of RT distributed computing realized with a distributed computer system structured in the form of an object network. Several approached proposed in recent years for extending the conventional object structuring scheme to suit RT applications, are briefly reviewed. Then the approach named the TMO(Time-triggered Message-triggered Object) structuring scheme was formulated with the goal of instigating a quantum productivity jump in the design of distributed time triggered simulation. The TMO scheme is intended to facilitate the pursuit of a new paradigm in designing distributed time triggered simulation which is to realize real-time computing with a common and general design style that does not alienate the main-stream computing industry and yet to allow system engineers to confidently produce certifiable distributed time triggered simulation for safety-critical applications. The TMO structuring scheme is a syntactically simple but semantically powerful extension of the conventional object structuring approached and as such, its support tools can be based on various well-established 00 programming languages such as C++ and on ubiquitous commercial RT operating system kernels. The Scheme enables a great reduction of the designers efforts in guaranteeing timely service capabilities of application systems.

교통수요관리(travel demand management)는 통행수요를 적절히 제어함으로서 교통혼잡을 최소화시키려는 목적으로 시행되는 제반 교통정책이라 할 수 있다. 교통수요를 적절히 관리하기 위해서는 먼저, 정책목표를 설정하고 이를 달성할 수 있는 최적의 정책변수들을 찾아야 하는데, 현재 이에 대한 연구는 미흡한 실정이다. 이런 측면에서 본 연구는 설정된 정책목표를 달성하기 위한 교통수요관리모형과 이를 풀기 위한 알고리듬을 제시한다. 교통수요관리모형은 2가지로 개발되는데, 첫 번째 모형은, 기점과 종점간 평균 통행시간을 대상으로 목표치를 설정한 후 이 목표치를 달성하기 위한 적정 통행수요를 구하는 문제이며, 두 번째 모형은 혼잡이 심한 특정한 지역을 대상으로 해당지역에 포함된 링크의 교통량/용량비가 일정한 목표수준을 유지되도록 하는 최적 통행수요를 구하는 문제이다. 간단한 예제 교통망을 대상으로 본 연구에서 제시한 모형들을 평가한다.

지금까지 테스트 데이터를 자동으로 생성하기 위한 대부분의 연구는 프로그램에 포인터가 존재하지 않는 경우만을 대상으로 하였다. 최근에 포인터가 있는 경우에도 테스트 데이터를 자동으로 생성할 수 있는 방법들이 제안되었지만 테스트할 프로그램 경로를 완전하게 명시해야 하는 경로 기반 방법이거나 프로그램을 실제 실행해야 하는 방법들이다. 이 논문에서는 프로그램 경로를 완전하게 명시하지 않아도 포인터가 있는 프로그램에 대하여 테스트 데이터를 생성할 수 있는 새로운 방법을 제안한다. 제안된 방법은 테스트 데이터 생성 문제를SAT(SATisfiability) 문제로 변환하고 SAT 해결도구를 이용하여 자동으로 테스트 데이터를 생성하는 정적 방법이다. 이를 위해 프로그램을 1차 관계 논리 언어인 Alloy로 변환하고 Alloy 분석기를 통하여 테스트 데이터를 생성한다.

Administrative city has been developed step by step aiming to being a public transport-oriented new city. In spite of its primary goal, administrative city is dominated by car-oriented tansportaion system because the supply of public transportation has not been adequately and timely performed. In this study, we investigate the current situation related to (public) transportation use in administrative city. Also, we examine the issues of traffic system through a survey on residents' consciousness about public transportation use. Additionally, the analysis of demand elasticity according to the change of the conditions of using public transportation and passenger car is conducted for passenger car users. As a result, it is analyzed that as the neighborhood is more stabilized after the completion of development the resistance to the abandonment of passenger car is higher when the tide demand control method is introduced. Therefore, it is concluded that pre-emptive public transportation supply and the management of car demand management are necessary for the activation of public transportation in Administrative city.

In the cases of the major cities, high poverty rate of the elderly, immature pension policies, and insufficient market conditions, policies and services for the employment of the elderly decrease the desire for the job participation. It is time to prevent the problems of the elderly, and induce the reachable seniors to participate in social activities. This research provides the location-based, customized job-search service for the elderly in order to actively support the participation in the economic activities of the elderly. The goal of SSJS(Smart Senior Job Search) is to provide the individual elderly with the customized position. It prints the appropriate positions near user location based on the residential area, job classification, and the physical condition, and provides the mash-up of the selectable job range in the unit distance based on the map. This customized service, which enables the seniors to select the type of the jobs based on their physical, mental and life conditions of the seniors, supports the participation in economic activities of the elderly people, and contribute to the expansion of the social job positions for the elderly and the equalization of the local development.

This study attempts to apply process drama in teaching Korean speaking. For that goal, the first part of the study introduces the main features of process drama exploring the possible use of teaching Korean speaking, and the second part presents a concrete example of developing a unit of the Sejong intermediate Korean conversation coursebook which was designed using a process drama method. Process drama is a process-oriented drama activity which progresses only with the teacher and students' spontaneous participation. With its unique meaning-oriented interaction paradigm, it has been suggested as an effective way of teaching and learning a foreign language. Since it emphasizes students' spontaneity, cooperation, and authentic communication, it commonly provides plenty of opportunities for students to interact in a meaningful context. Despite its effectiveness in teaching speaking, it has rarely been used in KFL contexts. Considering the limited opportunities to practice speaking in KFL classrooms, using a communication-rich activity such as process drama would be an optimal solution. This study, therefore, examines possible application of process drama in teaching Korean speaking, and introduces sample speaking materials designed for KFL intermediate learners.

병행성(concurrency)과 객체지향 패러다임을 통합하는 문제가 여러 해 동안 많은 사람들의 목표가 되어 왔다. 병행 프로그래밍과 객체지향 프로그래밍 기법을 결합한 병행 객체지향 프로그래밍 언어는 병행 응용 프로그램을 개발하는데 여러 가지 이점을 얻을 수 있다. 그러나 병행성과 상속성은 서로 충돌하는 특성을 가지기 때문에 캡슐화를 심각하게 파괴하지 않고는 동시에 사용하는 것이 어렵게 된다. 이러한 상속변칙 현상은 응용성을 제한하게 되고, 동기화가 발생하는 모든 문제를 처리하지 못하게 된다. 본 논문에서는 상속성과 객체 기반의 병행성 사이의 충돌 현상 해결에 행위 기술 방정식을 도입하였다. 그 결과, 여러 가지 상속 변칙 문제를 해결할 수 있고 메소드의 재정의가 불필요하게 되었다. 따라서 동기화와 함수 코드의 재사용을 인하여 유연성을 가진 병행성 모델을 제공할 수 있다.
