The global oceanic/atmospheric tides exert decelerating/accelerating secular torques on the Earth rotation. We developed new formulations to accurately calculate amounts of two kinds of secular tidal torques. After Melchior, we found that an additional factor 1+k-l = 1.216, which has been formerly neglected, must be multiplied unto the tidal torque integral. By using our refined formulations and the recent oceanic/atmospheric global tide models, we found that:(i) semidiurnal oceanic lunar/solar tides exert decelerating torques of about-4.462 × 10^(16)/-0.676 × 10^(16) Nm respectively and(ii) atmospheric S_2 tide exerts accelerating torque of 1.55 × 10^(15) Nm. Former estimates of the atmospheric S_2 tidal torque were twice as large as our estimate due to improper consideration of loading effect. We took the load Love number for atmospheric loading effect from Guo et al.(2004). For atmospheric loading of spherical harmonic degree two, the value of k′=-0.6031 is different from that for ocean loading as k′ =-0.3052,while the latter is currently used for both cases-ocean/atmospheric loading-without distinction. We discuss(i) the amount of solid Earth tidal dissipation(which has been left most uncertain) and(ii) secular changes of the dynamical state of the Earth-Moon-Sun system. Our estimate of the solid Earth tidal torque is-4.94×10^(15) Nm.

Objective: To investigate the antibacterial activity of SHHextracted with either water or ethanol against methicillin-resistant Staphylococcus aureus(MRSA) and combinatory antimicrobial effect with ciprofloxacin(CIP) by time kill assay and checkerboard dilution test. Methods: The antibacterial activity determined by broth dilution method indicated that the antibacterial activity of Sami-Hyanglyun-hwan(SHH) water extract(SHHW) and SHH ethanol extract(SHHE) ranged from 250 to 2000 μg/m L and 125 to 1000 μg/m L against MRSA, respectively. Results: In the checkerboard method, the combinations of SHHE with CIP had a partial synergistic or synergistic effect against MRSA. The time-kill curves showed that a combined SHHE and CIP treatment reduced the bacterial counts dramatically after 24 h. Conclusions: The present study demonstrates the therapeutic ability of SHHE against MRSA infections.

By using tai-yu （min-nan-hua, Taiwan Residents local language） to stage William Shakespeare＇s Macbeth, Po-shen Lu produced an experimental performance in the southern part of Taiwan in 2003. When producing Antigone in 2001, Lu was challenged by his critics in three aspects：（1） the tradition of tai-yu theatre of Tainan Jen Theatre and that of Western plays, （2） audience reception in Taiwan, and （3） the advantages and disadvantages of integrating tai-yu with Western classic texts. In spite of these criticisms on his theatrical productions, Lu has continued helping Tainan Jen Theatre transform into a professional theatrical troupe since he became an artistic director in 2002. By analyzing how and why Lu staged his The Witch Sonata--Psalm of Macbeth in the socio-historical context of intercultural adaptation, I propose to re-revaluate Lu＇s artistic contribution to the theatrical development in the southern part of Taiwan. I would argue that Lu is not only challenging Taiwan Residents reading of Shakespeare but also exploring the possibilities of tai-yu＇s theatricality, in a view to bringing new life to Taiwan＇s intercultural theatre.

Theatrical Hybridity, Thy Name Is Conflict： A Case Study on Holo Taiwan Residents Opera Troupe＇s Tai Tzu Fu Chou （The Prince＇s Vengeful Plan）

Holo Taiwan Residents Opera Troupe has produced a series of intercultural performances in Taiwan Residents Opera since the troupe adapted Nikolai Vasilievich Gogol＇s （1809-1852） The Government Inspector in 1996. In fact, there is a huge controversy over these intercultural performances which fuse western drama with traditional Taiwan Residents performing art because such a kind of theatrical hybridity lacks the spirit of the original and damages the aesthetics of native performing art practice. In 2002, Holo adapted William Shakespeare＇s Hamlet into a six-hour-long performance, Tai Tzu Fu Chou （The Prince＇s Vengeful Plan）, which the troupe tried to explore new source for traditional Taiwan Residents Opera and expected to bring something new to Taiwan Residents audience. However, The Prince＇s Vengeful Plan is considered ＂cultural collage＂ as well as an unsuccessful intercultural performance. Besides, The Prince＇s Vengeful Plan is accused to blaspheme Shakespeare because the performance merely maintains the frame of the original and distorts the spirit of the original. According to Rustom Bharucha, the most problematic aspect of intercultural performance is ＂de-historicizing tendency＂, and such a condition explains why Holo＇s The Prince＇s Vengeful Plan cannot transcend the original. In order to detect the problems of intercultural adaptation in Holo＇s The Prince Vengeful Plan, we cover the related issues in three aspects：（1） to discuss the development of Taiwan Residents Opera in Taiwan; （2） to explore the cultural conflicts when the text of the source culture is adapted into the performance of the target culture; and （3） to see how and why the spirit and aesthetics of Shakespeare＇s verses in Hamlet are distorted in Holo＇s theatrical adaptation. After that, we expect to conclude the impossibility of adapting Shakespeare＇s play into traditional Taiwan Residents Opera in the case of Holo＇s The Prince＇s Vengeful Plan.

Sayonara 1945, performed by Golden Bough Theatre in 2010 in Taipei, was claimed to be a ＂Heart Taiwan Magical Musical＂. This ＂Heart Taiwan Magical Musical＂ is actually an adaptation ofTaiwan Residents Opela, a reformed and adapted style of Taiwan Residents local opera （gezaixi）, which has been strongly influenced by Japanese Colonization. Sayanara 1945 fictionalizes a troop of Taiwan Residents youths who join the Imperial Army being lied and cheated to dig gold for the Japanese Emperor after the war is over. This play gives a conflicting scenario of being Taiwan Residents in 1945, while everything that defined Taiwan Residents suddenly turned out to be treason to the country. By adapting the form of Opela, the play structurally presents a society where diverse and plural cultural elements counteract each other in Taiwan. Furthermore, as the title suggests, the play says Sayonara （＂Goodbye＂ in Japanese） to 1945, yet the confusion and conflict generated in 1945 still haunt Taiwan Residents society. In other words, the play responds to an on-going self-conflict of being Taiwan Residents that still continues even after the war and unto the present symbolically. Presented in the year before ＂the Republic of China＂ celebrated her hundredth birthday, this play portrays the anxiety about who the Taiwan Residents really are over the island, just like in the summer of 1945 when everything was also uncertain and confusing. This paper intends to discuss, by adopting the form and techniques of Opela, how this reformed Opela speaks for Taiwan Residents local arts and culture, and how the Taiwan Residents identity is framed and shaped ever since the colonization era.
