Chia-Ming Wang and His Popular Culture Trilogy
No full text王嘉明「常民三部曲」 中文摘要 台灣莎士比亞的妹妹們的劇團導演王嘉明系列作品「常民三部曲」，取材自台灣常民流行文化，將「十年」一代視為其創作概念，歸納整理一九七零、八零、九零三個世代區間台灣娛樂產業與民生文化的大事件，推出作品分別為首部曲八零年代《麥可傑克森》、二部曲《李小龍的阿砸一聲》、三部曲《SMAP X SMAP》。三部作品依台灣社會發展進程的文化實況，展現各自獨立迥異的表演形式與語言風格：《麥可傑可森》以模仿八零年代知名人士與重現經典節目串聯的尾牙綜藝秀形式，以美國流行天王麥可傑克森歌曲作為貫穿，呈現戒嚴到解嚴的民間心理活動；《李小龍的阿砸一聲》為六代神話家族故事，透過社會符碼的挪用與新詮，書寫富含浪漫色彩的國族寓言；《SMAP X SMAP》處理九零年代日劇風潮，透過日劇十一話外加特別篇SP的演出結構，配合王嘉明自創的日台語混雜的新語言，在觀眾面前呈現電視電影影像由拍攝到後製的商品製造過程，玩弄影像虛構與真實界限的兩面關係。 「常民三部曲」為王嘉明作品中至今唯一的系列創作，有利於研究者對於創作者個人的創作動機與歷史觀作整體觀察。本論文試圖以台灣七零、八零、九零三個世代的時代特色與三部作品相互參照，討論王嘉明在史實與戲劇間穿梭的編導手法。Chia-Ming, Wang and His Popular Culture Trilogy Abstract Chia-Ming Wang, the director of Shakespeare’s Wild Sisters Group, based his theatre series Popular Culture Trilogy on Taiwanese everyday life. Using “decade” as the main creative concept, Chia-Ming’s Trilogy divides Taiwan’s modern history into three parts, 1970s, 1980, and 1990s. The first episode Michael Jackson-Back to the 80’s focuses on entertainment and parody, trying to reproduce the mentality of Taiwan society from the period of martial law to the period after lifting the martial law. The second episode Bruce Lee-Welcome to the 70’s is a mythological fable dealing with nationality imagination. The third episode SMAP X SMAP-In love with the 90’s ironically plays the duality between image and theatre. Bearing the structure commonly seen in Japanese drama, SMAP X SMAP-in love with the 90’s uses a new kind of spoken language mixed with both Taiwanese and Japanese, sometimes together with English, forcing the audience to rely on subtitles to understand the meaning of the performance. Popular Culture Trilogy is the only series of Chia-Ming, Wang so far, which provides a great opportunity for those interested in Chia-Ming’s works to look into his idea about history, directing style and creation concepts. The article aims at discussing the connections between Taiwan historical facts and the trilogy of theatre works, and provides plenty of personal views about the important director of Taiwanese modern theatre

Abstract
The commercialization of sport is not only a key factor to accustom the modern sport to the society, but also a outcome of the capitalistic society. In the same way, the modern Olympic Games played a major paradigm within the sport or society and intended to pursue the commercial benefits. The aims of the study were to analyze the social structure of the sport commercialization within the modern Olympics.
Using the methodology of structural functionalism, documentary analysis, and synchronic and diachronic analysis the study would discuss the structural relationships among organization, politics, economy and culture of sport commercialization in the modern Olympics. The results of the study are concluded as follows:
1. Three stages of the development of the modern Olympics’ sport commercialization were identified as embryonic stage (1896~1972), growth stage (1973~1984), and maturity stage (1985~).
2. The organizational, political, economical, and cultural power have reciprocally predominated the structural relationship of the modern Olympics’ sport commercialization, and have changed the needs of the related organizations of International Olympic Committee, thus have driven the revolution of sport commercialization.
3. The strengths of the modern Olympics’ sport commercialization were not only to help the development of the host community, but also to push the development of global sport forward.
4. The modern Olympics’ sport commercialization should pay attention to the problems about political hegemony of sport, over-commercialization of sport, sport class, and annoyance of sport organization.
Keywords: the Olympic Games, the commercialization of sport
Mechanical Properties, Slip and Nucleation of the 1999 Chia-Yi Earthquake: the Question of Static Stress Influence from the 1999 Chi-Chi Earthquake
No full textWe investigate the effects of static stress transfer from the 1999 Chi-Chi Taiwan earthquake to the subsequent Chia-Yi earthquake by using Coulomb failure assumptions. Our results provide substantive evidence that changes in normal stress unclamped the Chia-Yi rupture surface but that changes in shear stress discouraged the Chia-Yi earthquake. Combining these two counter effects, we determine that the Chia-Yi earthquake could have been activated by the Chi-Chi earthquake provided that there was an increase in Coulomb failure stress of less than 0.2 bars on the grounds that a friction coefficient of 0.7 ≤ μ ≤ 0.75 and a Skempton’s coefficient of 0.75 ≤ β ≤ 0.85 are very feasible mechanical conditions. Equally important, we find a poor correlation between the changes in Coulomb failure stress from the Chi-Chi earthquake and the slip amplitudes of the Chia-Yi earthquake, which implies that fault heterogeneity could have very well reduced the effects of the changes in static stress caused by the Chi-Chi earthquake. Beyond this, the concentration of transient stress at the rupture front of the Chia-Yi earthquake was evidently large enough to have overcome the influence of fault heterogeneity and to have dominated slip amplitude there
Emprego da tecnologia supercrítica para a valorização do resíduo de semente de chia (Salvia hispanica)
Full text linkDissertação (mestrado) - Universidade Federal de Santa Catarina, Centro Tecnológico, Programa de Pós-Graduação em Engenharia de Alimentos, Florianópolis, 2014.A chia (Salvia hispanica) é uma planta cultivada nas Américas do Sul e Central, cuja semente é fonte de antioxidantes naturais e ácidos graxos essenciais. O presente estudo avaliou a obtenção de extratos de torta de chia, subproduto proveniente da extração do óleo de chia. Foram aplicadas as técnicas a baixa pressão como extração em Soxhlet (SOX), ultrassom (US) e maceração (MAC) utilizando etanol (EtOH), hexano (Hex) e acetato de etila (EtOAc) como solventes, a fim de comparar com o processo de extração supercrítica (ESC). As operações de ESC foram realizadas com pressões de 150 bar a 300 bar e temperaturas de 40 °C e 50 °C empregando o CO2 como solvente. Também foi realizada a aplicação de EtOH e EtOAc como cossolventes no processo de ESC em concentrações de 2,5 até 7,5 %. O processo de extração supercrítica sequencial (ESC-S) foi estudado, o qual possui duas etapas de extração, com uma despressurização rápida do sistema entre a primeira e a segunda etapa. A construção da curva cinética e modelagem matemática de processos de ESC e ESC-S foram executadas, além da estimativa de custos de manufatura da instalação de uma unidade industrial de ESC. Todos os extratos obtidos foram submetidos a análises de atividade antioxidante (método ABTS), teor de fenólicos totais (TFT), perfil de ácidos graxos e atividade antimicrobiana. Nas extrações a baixa pressão, os maiores rendimentos foram obtidos utilizando SOX com EtOH (15,4 ± 0,4 %). Nas ESC com CO2 puro, a pressão de 300 bar permitiu alcançar rendimentos de até 10,6 ± 0,2 %, na maior temperatura estudada. A utilização de cossolvente causou aumento no rendimento de extração (11,3 ± 0,1% utilizando EtOH a 7,5%). Os extratos obtidos em extrações a baixa pressão com EtOH e EtOAc obtiveram os melhores valores de TFT e atividade antioxidante. A utilização de cossolvente afetou positivamente os resultados de TFT e atividade antioxidante dos extratos de ESC. O perfil de ácidos graxos dos extratos confirmou altos teores de ácido linoleico e a-linolênico em todos os extratos testados. Extratos obtidos pelas diferentes técnicas mostraram atividade antimicrobiana contra B. cereus. A ESC-S com despressurização rápida teve efeito positivo com relação ao rendimento, onde foi atingido rendimento de 8,7 ± 0,2%, estatisticamente igual ao rendimento obtido em ESC na mesma condição, porém reduzindo o tempo de extração pela metade. A realização da segunda etapa de ESC-S utilizando EtOH 7,5% ocasionou um aumento no TFT dos extratos obtidos. O modelo que melhor se ajustou as curvas experimentais foi o modelo de Martínez et al. (2003). Segundo o modelo de Sovová (1994), para os processos de ESC e primeira etapa de ESC-S, o mecanismo de convecção foi mais representativo. Na segunda etapa de ESC-S o mecanismo de difusão também mostrou representatividade. A ESC-S quando realizada até a etapa de despressurização (ESC-Desp) mostrou ser um processo economicamente viável e lucrativo para aplicação em escala industrial, com valores de extrato competitivos com os valores de mercado, gerando extratos de alta qualidade em um menor tempo de processo.Abstract : Chia (Salvia hispanica) is a plant cultivated in South and Central America, whose the seed is a source of natural antioxidants and essential fatty acids. The present study evaluated the extracts attainment from chia seed cake, which is a byproduct from chia seed oil extraction process. It were applied low-pressure techniques, like Soxhlet extraction (SOX), ultrasound assisted extraction (US) and maceration (MAC) using ethanol (EtOH), hexane (Hex) and ethyl acetate (EtOAc) and as solvents with the objective of comparing with the high pressure process, performed by supercritical fluid extraction (SFE). SFE were performed at pressures from 150 to 300 bar and temperatures of 40 °C and 50 °C, using CO2 as solvent. It was also performed an application of EtOH and EtOAc as cosolvents on SFE process, using concentrations from 2.5 to 7.5%. A sequential supercritical fluid extraction (S-SFE) process was studied, wich includes two steps of extraction, with a fast depressurization of the system between the first and the second step of extraction. The kinetic extraction curves of SFE and S-SFE processes were built and mathematical models adjusted the experimental data. It were also performed an estimative of manufacturing costs from installing a supercritical fluid extraction industrial unit. All extracts was submitted to antioxidant analysis (ABTS method), total phenolics content (TPC), fatty acids profile and antimicrobial analysis. Among low-pressure extraction, the highest yield was achieved using SOX with EtOH (15.4 ± 0.4 %). Among the SFE assays using pure CO2, the pressure of 300 bar allowed to achieve yields up to 10.6 ± 0.2 %, in the highest tested temperature. The use of a cosolvent caused increase in yield (11.3 ± 0.1% using EtOH 7,5%). Extracts obtained by lowpressure techniques using EtOH and EtOAc showed the best values of TPC and antioxidant activity. The using of a cosolvent affected in a positive way the results of TPC and antioxidant activity of SFE extracts. The fatty acids profile of the extracts confirmed the high content of linoleic and a-linolenic acids in all tested extracts. Extracts obtained by different techniques showed antimicrobial activity against B. cereus. SSFE process with fast depressurization caused a positive effect in yield, achieving a yield of 8.7 ± 0.2%, statiscally equal to the yield obtained by SFE using the same condition, but reducing the extraction time by half. The performance of the S-SFE second step using EtOH 7.5% caused an increase in the TPC of the obtained extracts. Martínez et al (2003) was the model which best-adjusted experimental data. According to Sovová s model (1994), in S-SFE first step and SFE processes, the convection mechanism was more representative. In the S-SFE second step, the diffusion mechanism showed to be representative. S-SFE process, when realized until the depressurization step (SFE-Desp), showed to be an economically viable and profitable process on an industrial scale application, with values of extract competitive with market values, generating high quality extracts in a shorter process time
