The Tainan University of Technology, also known as Tainan Tech , is a private university serving approximately 10,000 students in the Tainan metropolitan area in southern Taiwan. The main campus sits in Yongkang District of Tainan. The school, founded in 1964 to provide professional training for women, opened its doors in 1965 as the Private Tainan Junior College of Home Economics. The school subsequently became the Tainan Women's College of Arts and Technology . Wikipedia.

Recently, a smart card based authentication and key agreement scheme preserving the user anonymity was proposed by Wang, Juang and Lei, that is designed to provide users with secure activities in ubiquitous computing environments. The authors proved that their scheme delivers important security properties and functionalities, such as without maintaining password/verification tables, freedom on password selection and alteration, mutual authentication, user anonymity, no time synchronization problem, key agreement implementation, forgery attack resistance and computation efficiency. However, we show that Wang et al.'s scheme has potential security flaws, which enable malicious attackers to counterfeit an application server to spoof the victim client and damage the security of session key and the property of user anonymity. In this paper, we propose an enhanced version of Wang et al.'s scheme to remedy these flaws. The proposed scheme not only ensures the merits of their scheme but also enhances the security of their scheme without raising any computation cost. Source

Cancer Treatment Reviews | Year: 2012

Cancer metastasis is the major cause of cancer-related death, and chemoprevention is defined as the use of natural or synthetic substances to prevent cancer formation or cancer progress. Evidence that phenolic compounds may have a potential inhibitory effect on cancer invasion and metastasis is increasingly being reported in the scientific literature. Curcumin, resveratrol, and their related derivatives are the most studied compounds in this topic so far; gallic acid, chlorogenic acid, caffeic acid, carnosol, capsaicin, 6-shogaol, 6-gingerol, and their corresponding derivatives are also suggested to be the active members of the phenolic family on anti-invasion and anti-metastasis. Because metastasis occurs through a multistep process, these bioactives might act on a variety of stages of the metastatic process to prevent tumor cells from metastasizing. This review summarizes the common protein targets and signaling pathways for the inhibition of invasion and metastasis as well as past publications on the in vitro and in vivo effects and molecular mechanisms of phenolic acids, monophenol, polyphenol, and their derivatives, except flavonoids, on cancer invasion and metastasis. Based on these data, we conclude that the daily consumption of natural dietary components that are rich in phenolics could be beneficial for the prevention of cancer metastasis. © 2011 Elsevier Ltd.

A novel model is presented to obtain exact energy spectrum, Landau levels (LLs) and wave functions in AA-stacking N-layer Graphene under the influence of perpendicular electric and magnetic fields. A particular unitary transformation to deal with the broken mirror symmetry caused by a perpendicular electric field can transform an AA-stacking N-layer graphene into N independent graphene-like layers. The exact energy spectrum of a graphene-like layer is equal to E= EMLG+ε, where EMLG is the energy spectrum of a monolayer graphene and ε is controlled by the magnitude of electric field and layer number. The associated wave functions are clearly specified. Such a method is applied to analytically study the combined effect of the vertical electric field and magnetic fields on LLs and wave functions in AA-stacking N-layer graphenes. An analytical formula of the gate-tuned LLs clearly exhibits the dependence of LLs on the number of layers, strength of gated field and magnetic fields. © 2013 Elsevier Ltd. All rights reserved.

Cancer and Metastasis Reviews | Year: 2012

Cancer metastasis refers to the spread of cancer cells from the primary neoplasm to distant sites, where secondary tumors are formed, and is the major cause of death from cancer. Natural phytochemicals containing phenolic compounds have been widely demonstrated to have the capability to prevent cancer metastasis. Among phenolic compounds, flavonoids are a very large subclass, and they are abundant in food and nutraceuticals. The number of reports demonstrating that flavonoids are an effective natural inhibitor of cancer invasion and metastasis is increasing in the scientific literature. Catechin derivatives, (-)-epigallocatechin-3-gallate, (-)-epigallocatechin, (-)-epicatechin-3-gallate, and (-)-epicatechin, are the most studied compounds in this topic so far; genistein/genistin, silibinin, quercetin, and anthocyanin have also been widely investigated for their inhibitory activities on invasion/metastasis. Other flavonoids in dietary vegetable foods that are responsible for anti-invasive and anti-metastatic activities of tumors include luteolin, apigenin, myricetin, tangeretin, kaempferol, glycitein, licoricidin, daidzein, and naringenin. To effectively overcome the metastatic cascade, including cell-cell attachment, tissue-barrier degradation, migration, invasion, cell-matrix adhesion, and angiogenesis, it is essential that a bioactive compound prevent tumor cells from metastasizing. This review summarizes the effects of flavonoids on the metastatic cascade and the related proteins, the in vitro anti-invasive activity of flavonoids against cancer cells, and the effects of flavonoids on anti-angiogenic and in vivo anti-metastatic models. The available scientific evidence indicates that flavonoids are a ubiquitous dietary phenolics subclass and exert extensive in vitro anti-invasive and in vivo anti-metastatic activities. © 2012 Springer Science+Business Media, LLC.

Although computer- and Internet-aided learning for hearing-impaired students has been a trend in the modern days, a few studies were done to examine their effectiveness in strengthening learning motivation and, in turn, enhancing learning efficiency. This study attempts to establish an interactive self-regulated learning environment and employs Attention, Relevance, Confidence, Satisfaction motivation model, hyperlink technology, modular concepts and online learning community to design teaching contents and presentation of teaching materials. An empirical study was conducted to examine the effects of hearing-impaired students learning motivation and cognitive attitude of learning environment. The results showed that interactive and self-regulated learning environment could effectively strengthen learning motivation and promote positive learning behaviour in hearing-impaired students. © 2013 John Wiley & Sons Ltd.
