In order to reduce the damage of life and property caused by an automobile accident, we should design new car models and safety standard with reference to the data analysis and in-depth investigation of the accident. In-depth research and analysis of the current world other than the police investigation team (GIDAS, iGLAD, NHTSA, etc.) and collect in-depth data. Going to develop a safety policy to make it much safer cars based on this data. However, the country still does not have the advantage of KIDAS data Safety Policy Direction. In KNCAP tests, there is nothing in order to protect far side passengers even if far side impact causes approximately 50% injured people. Based on DBs like KIDAS (Korean In-Depth Accident Study) and GIDAS, far side passengers got injured as much as near side passengers did. So as to protect far side passengers, KNCAP has to change the test method of side crashes. In this study, injury severities to compare with ES-2, World SID and Thor dummies and the movements of far and near side passengers, SLED TEST was used.
FPGA를 이용한 ARM9 호환 마이크로프로세서 설계 및 구현

최근 고성능, 고효율 마이크로프로세서에 대한 요구가 증가함에 따라, 새로운 구현기법들에 대한 연구가 활발히 진행되고 있다. 본 논문에서는 고성능, 고효율 마이크로프로세서의 연구에서 필요한 연구 기반을 제공하기 위해 마이크로프로세서를 구현하였다. 본 논문에서 구현한 마이크로프로세서는 5단계의 파이프라인으로 구성되어있고, ARM9의 전체 명령어 중 75%를 구현하였다. 이러한 마이크로프로세서는 QuartusⅡ를 이용하여 합성한 결과 5,243개의 논리소자가 사용되었고 실험에 사용되는 FPGA 보드에서는 최대 50㎒로 동작한다. 또한, 마이크로프로세서 외에도 주파수 합성기, 메모리, 타이머, 비동기화송?수신기 등과 같은 주변장치를 함께 구성 여러 가지 테스트 프로그램 등을 통해 마이크로프로세서와 주변장치의 동작을 검증하였다. 본 논문의 목적은 FPGA 특성에 맞는 마이크로프로세서의 구현 기술의 축적을 통해 에뮬레이션을 이용한 다중코어 연구의 기반을 마련하는 것이다. With the recently increased demand on the high performance and efficiency microprocessor, there have been many studies on new implementation methodologies. In this paper, we implemented a microprocessor to provide the basis for studies on high performance and efficiency microprocessor. The implemented microprocessor consists of five-stage pipeline, which accounts for 75% of all ARM9 instruction. When this microprocessor was synthesized using QuartusⅡ, 5,243 logic elements were used. The microprocessor operates at up to 50㎒ on the FPGA board used in our experiment. In addition to the microprocessor, peripheral devices such as frequency synthesizers, memories, timers and non-synchronized transmitters/receivers were also configured. The operations of the microprocessor and peripheral devices were verified through various test programs. The purpose of this study is to provide basis for study on multi-core microprocessor using emulation by accumulating microprocessor implementation technologies regarding characteristics of FPGA.

The purpose of this study is to find the continuance intention to use for reCAPTCHA technology which has information security and social contributions (decrypting archives) according to the user's pro-social level. In this research, reCAPTCHA technique generally gives users to information security and decrypting archives. However, as a result of preliminary survey, most users were not even aware of information security and social contributions (decrypting archives) functions. Therefore, in this research, we will measure with two kinds of focus. The first is the assumption that there will be also a difference in the continuance use depending pro-social level of the user of information technology, second we explain only the function of information security to the first group as well as decrypting archives to the second group. Generally, pro-social means that degree of understanding and supporting to the other people's interest, actions, needs, help, and care. In this research, we assume that if users have a low level of others care, they might evaluate that reCAPTCHA technology's social contributions is low. While they have a high level of others care, they recognize reCAPTCHA technology's social contribution is high and then they tend to use this technology continuously. Through this research, we finally find the most efficient way to increase the degree of continuance use of information technology.

블로그는 정보 공유와 관계 형성의 유력한 미디어로 인정되고 있다. 그러나 기존의 기술수용 모델은 블로그와 같은 관계 지향적인 정보시스템에 대한 수용성을 설명하는 데 적합한지 증명되지 않은 상태이다. 따라서 본 연구의 목적은 블로그 사용에 영향 주는 요인을 규명하는 것이다. 이것을 위해 유력한 포털사이트인 네이버 블로거들을 대상으로 인지된 유용성, 인지된 격려와 실제사용의 인과 관계를 대중적 자기 인식, 자기노출과 텔레프레즌스를 변수로 검증하였다. 그 결과, 대중적 자기인식과 자기노출은 인지된 유용성과 인지된 격려의 유의미한 요인으로 보여지고 인지된 유용성과 인지된 격려는 블로그의 실제사용에 유의미한 영향을 주는 것으로 보여졌다. Recently, blogging has been regarded as a promising media for information sharing and relationship building. However, it is not quite sure if the technology acceptance model could be completely adopted also in relationship-based system such as blog. Hence, the purpose of this paper is to identify the factors affecting the usage of blogs. To do so, content analysis methodology is applied to extract meaningful factors affecting the usage of blogs in the opinions of the bloggers in a Korean portal site : Naver. We investigates the causal relationship among three factors ; perceived usefulness, perceived encouragement, and actual use in blogging. Moreover, public self-consciousness, self disclosure and telepresence are also considered as the determinants. The results show that public selfconsciousness and self disclosure are significant elements affecting perceived usefulness and perceived encouragement, while perceived usefulness and perceived encouragement both affecting the actual use of blogs.
