This paper reviews diverse IP mobility and fast handover mechanisms for seamless Internet services. Especially, fast handover mechanisms for the Proxy Mobile IPv6( PMIPv6) are categorized according to their approaches. Then, a new fast handover PMIPv6(FH-PMIPv6) mechanism is proposed using only L3 signaling message exchange. In the proposed FH-PMIPv6 mechanism, only local mobility anchor(LMA) exchanges L3 signaling messages with mobility access gateways(MAGs) for the fast handover operation. That is, inter-MAG signalling messages are not required for the fast handover operation. Therefore, unlike existing fast handover mechanisms, two relevant neighbouring MAGs need not set up the security association(SA) to protect fast handover related signaling messages and share SA related information. Moreover, the L3 triggering message is defined newly by standard ICMPv6 to trigger promptly the proposed mechanism. Analysis and comparison of the handover latency are performed for the proposed mechanism and existing mechanisms, which shows that the proposed FH-PMIPv6 mechanism has the favorable performance.

기존의 MIPv6는 오랜 시간동안의 핸드오버로 인하여 많은 패킷 손실 및 오랜 세션 단절을 야기시킨다. 이러한 문제점들을 향상시키기 위하여 Fast handover for Mobile IPv6(FMIPv6) 프로토콜이 개발되었지만 여전히 터널링에 기반한 라우팅 방법은 패킷 순서 어긋남 문제로 인하여 성능이 하락하는 문제를 야기한다. 최근 모바일 단말에서의 이동성 관리 부하를 줄여주기 위하여, 네트워크 이동성 기반인 Proxy Mobile IPv6(PMIPv6)가 제안되었다. PMIPv6는 모바일 단말에서 수행하던 이동성 관리를 네트워크 에이전트에서 해줌으로서 단말의 부하를 줄이고 이동성 관리 지연 시간을 줄일 수 있다. 본 논문에서는 PMIPv6에서 안정되고 향상된 최적화 라우팅 기술이 접목된 빠른 핸드오버 방법인 Fast Proxy Mobile IPv6(EF-PMIPv6) 제안한다. 제안한 EF-PMIPv6는 고속의 IAPP 기술 및 ND 기법을 이용하여 기존의 MIPv6와 PMIPv6 기법에 비하여 고속의 핸드오버를 지원해 줄 수 있다. 또한 수식분석을 통하여 제안한 방법의 향상된 점을 보여준다. 분석에 있어서는 다양한 파라미터들을 이용하여 제안한 방법과 기존의 방법들에 있어서 핸드오버 지연시간을 비교하였다.

3-dimensional magnetic resonance cholangiopancreatography (MRCP) images reconstructed using the maximum intensity projection technique were analyzed qualitatively in patients diagnosed with pancreatobiliary diseases to determine their diagnostic utility. Single shot fast spin echo (SSFSE), fast spin echo (FSE) and 3-dimensional reconstructive images were acquired from 20 patients diagnosed histologically with pancreatobiliary diseases using a 3.0T MR scanner. According to qualitative analysis, the fast spin echo images and 3-dimensional reconstructed images of the hepatic duct, gall bladder and common bile duct had a higher signal to noise ratio (SNR) than the single shot fast spin echo images. Fast spin echo images and 3-dimensional reconstructed images did not show any differences. The contrast to noise ratio of the hepatic duct, gallbladder and common bile duct on the fast spin echo images and 3-dimensional reconstructed images was higher than that of the single shot fast spin echo images. The fast spin echo images and 3-dimensional reconstructed images showed similar quality.

The purpose of this study is to identify the antecedents of consumers' decision postponement on purchasing fast fashion brands. Ongoing search behavior, overchoice confusion, and similarity confusion were considered as antecedents. It was hypothesized that ongoing search behavior influences decision postponement both directly and indirectly through overchoice confusion and similarity confusion. Data were gathered by surveying university students in Seoul, using convenience sampling. Three hundred five questionnaires were used in the statistical analysis, which were exploratory factor analysis using SPSS and confirmatory factor analysis and path analysis using AMOS. Factor analysis proved that ongoing search behavior, overchoice confusion, similarity confusion, and decision postponement were uni-dimensions. Tests of the hypothesized path proved that ongoing search behavior influences decision postponement indirectly through overchoice confusion. In addition, similarity confusion influences decision postponement. The results suggest some confusion reduction strategies for marketers of fast fashion brands. Suggestions for future study are also discussed.

There are electric double layer capacitance, polarization resistance and solution resistance in the interface between electrode and solution. Electrode process could be evaluated by the electrical impedance analysis. The necessities of the electrochemical cell analysis with high speed impedance analyzer are followings: minimization of the effects of electric stimulation on electrochemical cell and the concentration of reactive materials, and optimization of impedance signal resolution. This paper represents the design criteria for the selection and stimulation to develop fast impedance analyzer prototype for a electrochemical cell. It was suggested that the design of 470k sample/s sampling rate, 13 bit ABC resolution, and 140ms recording time is required for high speed impedance analysis system in frequency range between dc and 10kHz.

In this paper, we propose a fast encoding algorithm for scalable video encoding without compromising coding performance. Through analysis on multiple motion estimation processes performed at the enhancement layer, we show redundant motion estimations and suggest the condition under which the redundant ones can efficiently be determined without additional memory. Based on the condition, the redundant motion estimation processes are excluded in the proposed algorithm. Simulation results show that the proposed algorithm is faster than the conventional fast encoding method without performance degradation and additional memory.
