The National Assessment of Educational Achievement has been conducted in the form of sampling assessment until 2007, but it was converted into sampling assessment one hundred percent working with relevant whole students in 2008. Therefore, the necessity of new study on the national assessment system of educational achievement was on the rise. The National Assessment System of Educational Achievement, which was implemented in this thesis was designed to analyze educational achievement status all over the province, total score and score frequency distribution per subject, item difficulty and item discrimination, degree of attraction of wrong answers, educational achievement per subject, gender, region, office of education, school, individual and status of students with high educational achievement.

본 논문에서는 다양한 캐리 전달 방식(carry propagation scheme)이 단일 가산기 설계를 위하여 복합적으로 사용되는 가산기 구조물 제안하며. 이를 통하여 보다 향상된 delay-area trade-off 점들을 갖는 설계공간을 생성한다. 제안된 구조의 가산기는 각기 다른 캐리전달 방식의 하부 가산기 블록들을 캐리 입/출력 신호를 선형으로 연결한 구조이며, 기존의 단일 캐리전달 방식의 가산기와 달리, 다양한 delay-area trade-off 특성을 갖는 여러 종류의 캐리전달 방식을 비트 수준에서 조합하여 사용함으로써 보다 섬세한 delay-area 설계공간을 생성해낼 수 있다. 그러나, 제안된 가산기 구조의 설계공간은 다양한 캐리전달 방식이 비트 수준에서 할당되므로, 할당가능한 설계 조합은 설계하고자 하는 가산기의 비트 폭과 고려하는 캐리전달 방식의 수에 비례하여 폭발적으로 증가하게 된다. 따라서, 제안된 가산기의 효율적이며, 자동화된 설계공간 탐색 방범이 요구된다. 본 논문에서는 이를 해결하기 위하여 정수 선형 프로그래밍 (Integer Linear Programming, ILP) 방법을 이용하여 제안한 가산기의 최적화 문제를 형식화함으로써 효과적인 설계공간의 탐색 방법을 제안하였다.

In this paper, we implemented the GenJTAG, a CAD tool, which generates a code of boundary scan circuit supporing a board level testing and d BIST(Built-In Self Test) written in verilog-HDL. A boundary scan circuit code that supports user's own BIST instructions is generated based on the informations from the users. Most CAD tools hardly allow users to add their own BIST instructions because the generated code described in gate-level. But the GenJTAG generates a behavioral boundary scan circuit code so users can easily make a change on the generated code.

The future battlefield operation concept does not focus on advanced and complete weapon systems, but requires a new battlefield operation concept that can effectively demonstrate offensive power by combining a large number of low-cost, miniaturized weapons. Recently, research on the autonomous application of major technologies that make up the mission control system is actively underway. However, since the mission control system is still dependent on the operator's operating ability when operating multiple robots, there are limitations to simply applying the automation technology of the existing mission control system. Therefore, we understand how changes in operator capabilities affect multi-robot operation and propose an adaptive mission control architecture design method that supports multi-robot integrated operation by adjusting the level of autonomy of the mission control system according to changes in operator capability.

Currently, in the design process of civil structures such as bridges, it is common to make final products by repeating the process of redesigning, if the initial design is found to not meet the standards after a structural review. This iterative process extends the design time, and causes inefficient consumption of engineering manpower, which should be put into higher-level design, on simple repetitive mechanical work. This problem can be resolved by automating the design process, but the external analysis program used in the design process has been the biggest obstacle to such automation. In this study, we constructed an AI-based automation system for the bridge design process, including an interface that could control both a reinforcement learning algorithm, and an external analysis program, to replace the repetitive tasks in the current design process. The prototype of the system built in this study was developed for a 2-span RC Rahmen bridge, which is one of the simplest bridge systems. In the future, it is expected that the developed interface system can be utilized as a basic technology for linking the latest AI with other types of bridge designs.

This study is to maximize the efficiency of university libraries' human resources management by determining the followings : the relationship between the level of information technology(1T) implement and the job satisfaction of the librarians, the main factors that affect job satisfaction, and how organizational characteristics and individual characteristics affect job satisfaction. Questionnaire was sent to 485 librarians from 27 universities chosen by stratified sampling and the methods of ANOVA, T-test, and correlation analysis were used. The results of the analysis are as follows. 1) there is a significant difference in the level of job satisfaction and the motivation factor according to the level of implementation of IT. 2) There is a relatively high correlation among the participation in decision making, the leadership in implementing the IT, the IT support of the CEO and job satisfaction. 3) There is a significant difference in job satisfaction by the level of computer skills, and a relatively high correlation is shown in the training experience while implementing the IT and job satisfaction.

Information system audit, by checking overall matters about constructing and managing information system, has to contribute to improvement of information system's quality and improving performance of projects. For this, an auditor has to present objective corroborative facts which back up result of audit and ways of improvement, but in reality, general(especially businessmen's) cognition is that audit is biased by way too subjective opinions. Local experience and theoretical research until now propose that tools of automating audit will be an active means of systematically collecting and proposing these objective evidences of audit. This research not only verified that in the field of audit, phenomenon of technology application can be explained and predicted by applying TAM, but it also contributed in extending theoretical base on information technology and audit by distinguishing several characteristics which appear in the process of the model's application and analysis.

This study attempts to investigate the IT utilization and e-business level of the small and medium companies in order to facilitate their e-commerce efforts. Results show that they have basic IT infrastructures such as internet and PC, but they use their IT resources mainly for office automations. Major problems with such low level of IT utilization are in their lack of manpower, skill, and fund. Considering above issues, web hosting service is believed as a good measure to alleviate their problems. Hence, this paper suggests that utilization of the web-based ASP can be a viable solution for the currently revealed issues. Also, development of creative IT application(business) cases and their advertizement can lead small and medium finns to more productive IT investments, which requires more diverse IT performance measurements such as BSC(balanced scorecard), other than traditional ROI.

급변하는 환경속에서 중소기업이 살아남기 위해서 필수적으로 요구되는 것이 정보기술이다. 특히 최근에 와서 인터넷의중요성과 활용이 증대되고 있다. 본 연구에서는 중소기업의 인터넷에 관한 실태분석을 통하여 활용방안을 제시하고자 하였다. 전국의 중소기업 126개 업체를 대상으로 설문지를 배포하고, 회수된 82부중 64부를 실제분석에 사용하였다. 분석결과 중소기업에서는 인터넷에 대한 필요성은 강하게 느끼고 있지만, 인지도는 그리 높지 않았고, 사용시간도 낮은 수준이었으며, 주로 활용하고 있는 업무는 마케팅 업무였고, 활용되는 분야는 검색과 전자우편이 주를 이루었다. 인터넷의 활용으로 달성할 수 있는 성과로는 중소기업의 신속한 기술정보 제공으로 나타났다. 실태분석을 통하여 중소기업이 취할 수 있는 활용방안은 의사소통의 원활화, 업무자동화, 경영전략 단계 등임을 확인 할 수 있었다. 이상과 같이 중소기업이 인터넷을 활용하고 있는 정도는 미약하지만, 강한 필요성을 느끼고 있고 정부차원의 지원을 통해 인터넷은 중소기업의 필수 불가결한 정보기술, 나아가서는 경쟁무기가 될 수 있을 것으로 기대된다.
