Efficient Privacy Protection in Radio Frequency Identification Systems
Yuan Yang,이태석(Tae-seok Lee),XiaoYi Lu,인호(Hoh In),박명순(Myong-Soon Park) 한국정보과학회 2005 한국정보과학회 학술발표논문집 Vol.32 No.2
In today’ s hyper-competitive business environment, Radio Frequency Identification (RFID) technology is expected to enhance the operation efficiency of supplying chain management in both manufactures and retail industries. However, the widespread deployment of RFID tags may create new threats to user privacy, due to the powerful tracking capability of the tags. Many authentication protocols for RFID have been proposed. They are helpful preventing passersby being scanned to determine what articles they are carrying. However, most of them would not prevent the bigger physical tracking problem of RFID, especially when being tracked by the “constellation” of products they carry. We proposed this RFID scheme to prevent these tracking problems.

This study aimed to examine the effect of the ease of the transaction, the consumer interest, and the level of system security against acts of fraud on online shopping. Ease of transaction is measured from the transaction speed, high accuracy, high volume transaction, highly correlated, and ease of access are high. Measurement of consumer interests is including motivation, perception, learning, and memory. System security level measured from the privacy, integrity, autentication, availability, and access control.Sample selection is done by using purposive sampling method. The research data were collected from students of the Faculty of Economics, University of Trisakti. The samples used were 100 accounting students from semesters 1 to 9. The analysis technique used is multiple regression in SPSS version 23. The results showed that the factors such as the ease of transactions, consumer interest, and the security level of the system is partially measured by the transaction speed, high accuracy, high volume transaction are highly correlated. Meanwhile, ease of access is high, motivation, perception, learning and memory does not have a significant effect on the action of cheating but the privacy, integrity, autentication, availability. The access control can influence the actions of fraud significantly. Influence ease of transactions, consumer interest, and the security level of positive and significant impact on fraud actions simultaneously.

A FEEDBACK-DRIVEN BUBBLE G24.136+00.436: A POSSIBLE SITE OF TRIGGERED STAR FORMATION
Liu, Hong-Li,Wu, Yuefang,Li, JinZeng,Yuan, Jing-Hua,Liu, Tie,Dong, Xiaoyi IOP Publishing 2015 The Astrophysical journal Vol.798 No.1
<P>We present a multi-wavelength study of the IR bubble G24.136+00.436. The J = 1-0 observations of (CO)-C-12, (CO)-C-13, and (CO)-O-18 were carried out with the Purple Mountain Observatory 13.7 m telescope. Molecular gas with a velocity of 94.8 km s(-1) is found prominently in the southeast of the bubble, shaped as a shell with a total mass of similar to 2 x 10(4) M-circle dot. It was likely assembled during the expansion of the bubble. The expanding shell consists of six dense cores, whose dense (a few of 10(3) cm(-3)) and massive (a few of 10(3) M-circle dot) characteristics coupled with the broad linewidths (>2.5 km s(-1)) suggest that they are promising sites for forming high-mass stars or clusters. This could be further consolidated by the detection of compact H II regions in Cores A and E. We tentatively identified and classified 63 candidate young stellar objects (YSOs) based on the Spitzer and UKIDSS data. They are found to be dominantly distributed in regions with strong molecular gas emission, indicative of active star formation, especially in the shell. The H II region inside the bubble is mainly ionized by a similar to O8V star(s), of the dynamical age of similar to 1.6 Myr. The enhanced number of candidate YSOs and secondary star formation in the shell as well as the timescales involved, indicate a possible scenario for triggering star formation, signified by the 'collect and collapse' process.</P>

Background Quantification of mRNAs in gonads and other tissues at the early critical development stage of sex differentiation may help to provide a global view of regulatory mechanisms underlying sex differentiation. We have recently reported the transcriptomic profiling of fugu gonad associated with sex differentiation. Objectives This study attempted to identify the genes in the brain that are involved in gonadal differentiation and development. Methods In this study, a transcriptomic scan of potential candidate genes involved in sex differentiation was conducted in the brains of fugu larvae at 30 and 40 dah (morphological gonadal sex differentiation had not yet occurred). The dimorphic expression patterns of several candidate genes were verified using quantitative PCR. Results A total of 28.24 Gb of clean reads were obtained and 22,337 genes were identified in the brains of fugu larvae. These included 1008 novel genes that provide abundant data for functional analysis of sex differentiation. 229 genes were identified in the 30 dah larvae that were abundant in the XY brain and 21 that were abundant in the XX brain. In the 40 dah larvae, 325 genes were identified abundant in the XY brain and 174 were identified abundant in the XX brain. Conclusion This is the first investigation into the transcriptome of the fugu larvae brain at the early sex differentiation stage. The results obtained here will enhance the understanding of molecular mechanisms that underly fugu sex differentiation.
