Automatic detection of vehicles in front is an integral component of many advanced driver-assistance system, such as collision mitigation, automatic cruise control, and automatic head-lamp dimming. Regardless day and night, tail-lights play an important role in vehicle detecting and status recognizing of driving in front. However, some drivers do not know the status of the tail-lights of vehicles. Thus, it is required for drivers to inform status of tail-lights automatically. In this paper, a recognition method of status of tail-lights based on video processing and recognition technology is proposed. Background estimation, optical flow and Euclidean distance is used to detect vehicles entering tollgate. Then saliency map is used to detect tail-lights and recognize their status in the Lab color coordinates. As results of experiments of using tollgate videos, it is shown that the proposed method can be used to inform status of tail-lights.

Radio frequency identification (RFID) is an important and essential components of ubiquitous computing, with the development of wireless communication technologies and mobile computing environment. Recently, RFID becomes the mainstream application that helps fast handling and uniquely identifying the physical objects. It utilizes the electromagnetic energy for data transmission from a tag to a reader in the presence of arbitrary interference and noise. In order to employ the portable mobile RFID reader, a tag-collision problem between two or more adjacent tags should be considered. In this paper, we present the operation of RFID system in which numerous tags are present in the interrogation zone of a single reader at the same time. Since there may exist a number of tagged objects in the narrow area, multiple RFID tags may interfere each other, caused to degrade the data reliability and efficiency of the RFID system. In order to suppress interference signals from multiple neighboring tags, we present an application of Gold code for RFID communication system, which uses spread spectrum technique. In this RFID system, data bits are spreaded in each tags with the unique Gold code and the spreaded data bits are despreaded in the reader with the same Gold code. The performance analysis of the considered RFID anti-collision system is illustrated via computer simulation examples.

Since a NAND-flash memory is able to store mass data in a small sized chip and consumes low power, it is exploited on various hand-held devices, such as a smart phone and a sensor node, etc. To process efficiently mass data stored in the flash memory, it is required to use an index. However, since the write operation of the flash memory is slower than the read operation and an overwrite operation is not supported, the usage of existing index schemes degrades the performance of the index. In this paper, we survey the previous researches of index schemes for the flash memory and classify the researches by the methods to solve problems. We also present the performance factor to be considered when we design the index scheme on the flash memory.

The medical world has predicted that in 2020, the numbers of senile dementia patients in Korea will be more than 600,000. Currently, the distributions of dementia patients according to ages are 3% in the 70s, 23% between 85-89 years, and 58% over 95 years; further, it should be noted that the incidence rates sharply increase with age. Dementia, dubbed "disease of the 21st century", affects not only the patient but also the lives of the patient`s family, decreases the family`s quality of life, and sometimes accompanies enough burden and pain to destroy some families, and it is sometimes noted to cause significant problems in the society. This study was conducted at a dementia prevention center at a university by enrolling senior patients participating in the dementia prevention center program. The study aimed to actively develop dementia prevention programs and train specialized workforce for dementia prevention.
