무선채널에서는 잡음, 페이딩, 간섭 등에 의해 정보 손실이 발생된다. 이로 인한 오류발생은 무시할 수 있는 정도가 아니다. 양질의 음성 및 데이터 서비스를 제공하기 위해서는 통신 시스템에서 발생하는 비트 오류를 정정하는 기술이 꼭 필요하다. 이에 2세대 표준이면서 3세대 이동통신에서 사용되는 터보코드의 기본이 되는 비터비 디코더를 저면적으로 직접 구현했다. In the wireless channel, Information loss are generated by Noise, fading, and interference. The resulting error is not a negligible. It is necessary technology to correct a bit error to provide High-quality voice and data services in the communication system. Thus, Viterbi Decoder that G2 standard and code were derived Turbo code used in 3G mobile communications are directly implement as low area.

ACC Stop & Go is a full range adaptive cruise control system, which operates from 0㎞/h to 180㎞/h speed range. ACC Stop & Go system uses 77㎓ radar sensor to detect forward objects. Radar sensor detects the distance and the relative velocity of forward objects, and it decides target acceleration or deceleration values. The goal of this study is to develop hardware-in-loop simulator for applications of ACC Stop & Go system such as control algorithm development, fail management development and system verification and validation. The developed HIL simulator consists of a real time operating system, a sensor emulator, a test bench, and operation software. Especially this simulator needs not only a vehicle model, but a radar sensor model also. The radar sensor model enables the detection of forward objects, so that the distance and the relative velocity from forward object can be calculated in mathematical method. The test bench of simulator uses real vehicle’s driver seat and 3 dimensional graphic animation program, so it makes more realistic environment to testers. To verify this simulator’s performance, simulation results are compared with real field test results.

In this study, The control Logic is developed for assisting driver"s maneuver at urgent steering to avoid an obstacle at front. The start point of control is decided by driver"s intention. For appropriate steering assist torque to avoid the sudden obstacle target yaw rate is created through lane recognition of Camera Sensor and the relative distance from forward vehicle with Radar Sensor. Yaw moment is created to follow the target yaw rate as mentioned through steering torque of MDPS and differential braking with ESC module. Lastly, actual vehicle test is performed to verify it.

The active chassis control systems have been developed with vehicle electronic technology by achieving operating convenience and guaranteeing the stability of the vehicle. However, each controller has been optimized to meet its object according as developing each controller. In this paper, two integrated control logics - one that integrates Electronic Stability Control and Active Geometry Control Suspension and the other that integrates Electronic Stability Control and Active Front Steering - have been developed. The main control target of both logics is vehicle dynamics control under critical situations. The two logics were tested under various driving conditions in a reliable simulation environment and their synergetic effects were investigated. The results indicate that the proposed logics can yield better vehicle performance than the cases when the individual chassis control modules work without any integration scheme.

본 연구의 목적은 우리 조상들이 생활 속에서 향유해온 문학인 설화 중,교육 활동을 통해 교육적 효과를 거두는 이야기인 교육성취담의 서사 전개 양상을 분석해보고 그 특징과 의미를 밝혀봄으로써 설화의 전승 집단인 우리 조상들의 교육관에 대해서 규명해보는 것이다. 먼저 많은 설화 중에서 교육이 직접적인 소재가 되고,인간을 인간답게 만드는 긍정적인 변화활동이라 할 수 있는 교육의 정의에 부합할 수 있는 설화를 추출해 보았다. 그리고 교육을 통해 긍정적인 성취를 이루는 이야기 몇 편을 뽑아 보았다. 다음으로 이들 이야기의 서사단락을 구분하고 그 전개 양상을 분석해 보았다. 그리고 이들을 첫째,긍정적인 스승의 모습,둘째,교육방법 변화에 의한 성공,셋째,바람직한 의식 변화 등으로 묶어서 ‘교육성취담’으로 유형화하였다. 그리고 이들 이야기들이 지니는 특징과 의미를 밝혀 보았다. 그 결과 교육성취담은 여러 지역에서 전승되면서 실제 인물이 등장하는 등의 개연적인 이야기로 구성되어 긍정적인 인간 형성,스승에 대한 끝없는 신뢰,교육 자체의 중요성 강조 등의 의미를 담고 있음을 밝힐 수 있었다. 이러한 연구를 통해 ‘교육성취담’은 스승에 대해 끊임없는 신뢰를 바탕으로 교육을 통해 긍정적인 인간이 형성될 수 있다는 설화의 전승 집단인 우리 조상들의 긍정적인 교육관이 반영되었음을 확인할 수 있었다. The goal of this study is to look into educational achievement story in the folktales which has material of 'education activity' among the folktales, the literature that our ancestor has enjoyed in their lives and to seek out of the peculiarity and the meaning and how our ancestor considered about 'education' through looking into the descriptive development phases of those folktales. First of all, I tried to abstract some narratives that corresponds to the justice of education which can be said positive transformation makes human being as human and has direct writing material of education. As a consequence, I could introduce several tales that have related with education directly. And I examined the development aspect with classification in description paragraph_wise of those tales. As a results, firstly positive character of teacher, secondly success by the transformation of educational mariner and thirdly advisable change of awareness and through all of them I could materialize 'educational achievement story'. For next, I analyzed those narratives's meanings and peculiarities. I could find out several result as first, positive human formation, second, unlimited trust on a teacher, and third, meaning of emphasis for importance of education itself and so on. By such a result, I could confirm that educational narratives were reflected our ancestor's spirit that a positive man can be formed by putting education itself which is based on the unlimited trust in the teacher as the object.
