본 논문은 비주얼 정보, 오디오 정보, 중력 센서 정보에 기반한 멀티 모달 응급상황 인식 시스템을 제안한다. 제안된 시스템은 비디오 처리 모듈, 오디오 처리 모듈, 중력 센서 처리 모듈, 멀티모달 통합 모듈로 구성된다. 비디오 처리 모듈과 오디오 처리 모듈 각각은 이동, 정지 기절 등의 동작을 인식하여 멀티모달 통합 모듈에 전달한다. 멀티 모달 통합 모듈은 전달된 정보로부터 응급 상황을 인식하고 오디오 채널을 통하여 사용자에게 질문을 하고 대답을 인식함으로써 응급 상황을 재확인한다. 실험결과 영상에서는 91.5%, 착용형 중력센서는 94% 인식률을 보였으나 이들을 통합하면 응급상황을 100% 인식하는 결과를 보였다.

This paper presents implementation of parallel processing system for image processing. The parallel processing system proposed consisted of 16 processing elements, and multi-access memory system, and interface modules. The multi-access memory system we introduced is made up of a memory module selection, a data routing module, and an address calculation and routing module.

In this paper, we evaluated performance of mobile exchange control part. Queueing network model is used for modeling of mobile exchange control part. We developed a call control processing and location registration scenartio which has a message exchange function between processors in mobile exchange control part. A network symbol are used the simulation models that are composed of the initialization module, message generation module, message routing module, message processing module, message generation module, HIPC network processing module, output analysis module. as a result of computer simulation, we obtain the processor utilization, the mean queue length, the mean waiting time of control part based on call processing and location registration capacity. The call processing and location registration capacity is referred by thenumber of call attempts in the mobile exchange and must be satisfied with the quality of service(delay time).

This paper aims to propose an emergency recognition system using multimodal information extracted by an image processing module, a voice processing module, and a gravity sensor processing module. Each processing module detects predefined events such as moving, stopping, fainting, and transfer them to the multimodal integration module. Multimodal integration module recognizes emergency situation by using the transferred events and rechecks it by asking the user some question and recognizing the answer. The experiment was conducted for a faint motion in the living room and bathroom. The results of the experiment show that the proposed system is robust than previous methods and effectively recognizes emergency situations at various situations.

User Identity Module(UIM) is widely deployed in GSM(Global System for Mobile communications), Known as SIM(Subscriber Identity Module). We can expect that UIM will be also available for ANSI based third generation systems. Removable User Identity Module(R-UIM) is UIM for ANSI based third generation systems and Universal Subscriber Identity Module(USIM) is UIM for GSM based third generation systems. This paper identifies differences between R-UIM and USIM and studies global roaming in IMT-2000 systems.

전화를 통해 인터넷 정보를 들을 수 있는 보이스 포탈(Voice Portal) 서비스가 인기를 얻고 있다. Voice Portal 서비스란 알고자 하는 정보를 Speech Recognition System에 음성으로 명령하면 전화를 통해 음성으로 원하는 정보를 듣는 서비스이다. Authentication의 절차를 수행하는 SMS (Short Message Service) 서버 Module, PSTN과 Database 서버사이의 Interface를 제공하는 CTI (Computer Telephony Integration) Module, CTI 서버와 WWW (World Wide Web) 사이의 Voice XML Module, 정보를 검색하기 위한 Searching Module들이 필요하다. 본 논문은 Speech Recognition technology를 기반으로 한 CTI Module 설계를 구현하였다. 또한 인정 방식으로 Random한 일회용 password를 기반으로 한 SMS Authentication을 택하므로 더욱 더 안정된 서비스 제공을 목적으로 하였다.

This paper presents a design of 1-channel active dry electrode module for EEG from one's forehead. The IA(instrumentation amplifier) circuit inside the module is based on the configuration sown on the paper MettingVanRijn et al. We analyze the IA circuit to find out the related equation, and then compare its simulated characteristic with the result obtained from the real active dry electrode circuit. With the active dry electrode and the wet(Ag/AgCI) electrode connected to the separated analog processing module on one's forehead at the same time, their real time and FFT outputs of EEG are examined for comparison. The active dry electrode module has advantages over the wet electrode and its analog processing module: 1) The size of the analog processing circuit of the active dry electrode module is smaller than that of existing EEG analog processing module; 2) the total cost required to make the proposed analog processing circuit is much lower than that of the existing circuit, since the designed circuit needs smaller parts; 3) the electrical characteristic is comparable to the general EEG analog processing module even if the designed module has simpler circuit configuration.

해커들은 공격당한 시스템에서 공격자의 흔적을 숨기는 많은 테크닉을 오랫동안 개발해 왔다. 자신의 모습을 감추고 보다 용이한 재침입을 위해, 최근의 백도어(Backdoor)는 커널(Kenel) 구조와 코드 자체를 변경할 수 있는 기능을 가지고 있어서, 우리는 더 이상 커널 자체를 신뢰할 수 없게 되었다. 이 논문에서는 LKM(Loadable Kernel Module) Rootkit에 대한 체계적인 분석을 통해 이에 대한 보다 향상된 대응책을 찾고자 한다.

WAVE(Wireless Access for Vehicular Environment) System is a communication technology to monitor system failure and vehicle functions and management services to prevent possible incidents of driving a vehicle. In this paper, we have designed and implemented the mutual message processing through parameter between WME management module that manages WAVE system and MLME that manages the upper layer MAC(Media Access Control) module. Also, in order to verify the validity, we have carried out experiments to compare the speed of data processing by dividing data of 1Mbyte, 2Mbyte, 3Mbyte into the packets of 2KByte and 4KByte. Experiments data processing speed of 2KByte packet were shown about 173.62ms in 1MByte, 2MByte about 352.61ms, 3MByte about 550.13ms and, data processing speed of 4KByte packet, 1MByte approximately 87.56ms, 2MByte about 177.94ms, 3MByte about 277.18ms. Therefore, in WAVE system, the mutual messages processing through the parameters between WME and MLME module can be utilized in the various service of ITS(Intelligent Transportation Systems) depending on the speed of data processing.
