On Shen Pao-Chen¡¦s Thought Applied in the Model of Glolocalization for Taiwan ¡V The Responses of the Late Qing Dynasty¡¦s ¡§Westernization Movement¡¨ to the Globalization within the Process of the Capitalism

Lee, Tung-shun 11 September 2007 (has links)
As the late period of Qing Dynasty, there was a great event of ¡§ Botan Village Issue¡¨ Which happened in Taiwan, Shen Pao-Chen, the Imperial Commissioner who had been sent to take charge of Taiwan in 1874 & manage the defense to prevent the occupation of Taiwan by Japan, was impressed With the necessity of managing great reforms and infrastructures, including establishing new counties, civilizing the savage aborigines, moving governor to Taiwan, abolishing prohibition, reinforcing military administration, building shrines for Cheng Chen-Kung, and improving morale. In view of all Shen Pao-Ching¡¦s life, he was really a Pioneer ahead of his time for Taiwan¡¦s modernization. Aleader of nation must be with a certain spirit of adventure when his nation encounters heavy risk. Therefore, the spirit is what we can learn form him; he had established so mush infrastructure and reforms for Taiwan. All of things done by late Qing dynasty (Self-strengthening movement ) on Taiwan in process of globalization, social changes, the responses of the localization, and the transformation of ¡§ Glolocalization¡¨, which were rather mature and successful and it is able a key turning point in late Qing¡¦s policy for Taiwan.

No. of bitstreams: 1 Alcione Matos de Abreu.pdf: 2227189 bytes, checksum: f73eb32bdd92709cccf5f1c0b4627d4d (MD5) Previous issue date: 2012 / Universidade Federal Fluminense. Escola de Enfermagem Aurora de Afonso Costa / Este estudo teve os objetivos de avaliar os resultados clínicos e evolutivos do processo de reparo teci-dual em pacientes com úlcera venosa em uso da terapia compressiva inelástica (Bota de Unna) em comparação ao uso da terapia compressiva elástica (atadura elástica); e, analisar se existe variação significativa na área da úlcera ao longo de 13 semanas de tratamento nos dois grupos. Metodologia: Trata-se de um estudo clínico experimental randomizado e controlado, aberto, prospectivo, com abor-dagem quantitativa, realizado em um hospital universitário. A amostra foi de 18 pacientes, acompa-nhados por 13 semanas. Para alocação aleatória foi realizada uma lista através do software Biostat 5.0 que realizou o sorteio dos participantes em um dos grupos, onde metade destes utilizaram como trata-mento para as úlceras venosas a Bota de Unna, e a outra metade a atadura elástica. Todos os voluntá-rios atenderam aos critérios de inclusão. Este estudo foi aprovado pelo Comitê de Ética em Pesquisa da Faculdade de Medicina, sob o protocolo nº 327/2010 e CAAE:0252.0.258-000-10, os termos de consentimento e fotografia encontram-se de acordo com as Resoluções 196/96. A coleta de dados foi realizada durante seis meses, pela enfermeira pesquisadora e por uma bolsista de iniciação científica. Os dados foram analisados no SPSS 14.0 Windows, através de estatística descritiva e inferencial, e apresentados na forma de tabelas, quadros e gráficos. Entre os pesquisados, pôde-se identificar que (61,1%) eram homens e adultos, moradores de Niterói /RJ (66,6%) e com baixo grau de escolaridade (55,5%). Em relação às características clínicas das úlceras, encontrou-se que no grupo B, úlceras mais exsudativas, com maior tempo de evolução e maiores áreas. Já o Grupo A apresentou o maior numero de úlceras com presença no leito com tecido de hipergranulação e ou desvitalizado e destacou-se como a terapia compressiva mais confortável. O uso da Bota de Unna macerou as bordas das úlceras e a Gaze Petrolatum® levou a formação de crostas perilesional. Em relação a redução da área das úlceras venosas, pelo teste de ANOVA de Friedman, observou-se que existe queda significativa, ao nível de 5%, na área da úlcera apenas no grupo B (p < 0,0001) ao longo de todo o tratamento, mas pode-se dizer, que existe uma tendência do grupo A apresentar queda na área da lesão (p = 0,06), após a 5ª consulta. Conclui-se que a Bota de Unna apresentou melhor resultado em úlceras venosas com áreas superiores a 10 cm² e o uso da Gaze Petrolatum® com a atadura elástica em úlceras venosas inferiores a 10 cm². / This study aimed to evaluate clinical and evolutionist results of the process of tissues repairing in pa-tients with venous ulcer using the compressive inelastic (Unna Boot) comparing the usage of compres-sive elastic therapy (elastic bandage) and analyzing if there is a meaningful variation in the ulcer area with 13 weeks of treatment in both groups. Methodology: Concerning in a experimental, randomized and controlled, opened, prospective study with quantitative approach in a College Hospital. A sample of 18 patients was monitoring for 13 weeks. It was achieved a list of two groups in randomized draw by Biostat 5.0 software where half of participants used as therapy Unna Boot in venous ulcer and the other half of them used the elastic bandage one. All volunteers followed the inclusion criteria. This study was approved by The Committee of Ethics in research of Medical College; under the protocol number no 327/2010 and CAAE: 0252.0.258-000-10, terms of authorization and photography are in agreement to the resolutions 196/96. The data collection was done for six months by researcher nurse and a scholarship student of scientific study. Such data were analyzed in SAS 6.11, through descrip-tive and inferential statistic and performed in tables, squares and graphs. Among participants could identify that (61%) were adult male; inhabitants from Niteroi/RJ (66,6%) with a low degree of educa-tion (55,5%). Regarding to the ulcer clinical characteristics in Unna Boot group was found ulcers with more exsudation, with longer evolution time and larger areas. In elastic bandage group, a great number of ulcers with hyper-granulation and or desvitalization tissue on the bed was remarkable as the most comfortable compressive therapy. The usage of Unna Boot softened the ulcer borders and in the Petro-latum® Gaze took as a result a formation of a scab around the lesion. In relation to the reduction of venous ulcer area due to the ANOVA Friedman Test, analyzed that there is a meaningful decrease to the level of 5%, in the ulcer area in group B (p<0,0001) along of all the treatment, but there is a ten-dency of group A in performing a reduction in the affected area after the 5th consultation. Concluding that the Unna Boot performed better/satisfactory results in venous ulcer with area superior to 3.93 in². and the usage of Petrolatum® Gaze with elastic bandage in venous ulcer was inferior to 3.93 in².

Border Crossing Modeling and Analysis: A Non-Stationary Dynamic Reallocation Methodology For Terminating Queueing Systems

Moya, Hiram 2012 August 1900 (has links)
The United States international land boundary is a volatile, security intense area. In 2010, the combined trade was $918 billion within North American nations, with 80% transported by commercial trucks. Over 50 million commercial vehicles cross the Texas/Mexico border every year, not including private vehicles and pedestrian traffic, between Brownsville and El Paso, Texas, through one of over 25 major border crossings called "ports of entry" (POE). Recently, securing our southwest border from terrorist interventions, undocumented immigrants, and the illegal flow of drugs and guns has dominated the need to efficiently and effectively process people, goods and traffic. Increasing security and inspection requirements are seriously affecting transit times. Each POE is configured as a multi-commodity, prioritized queueing network which rarely, if ever, operates in steady-state. Therefore, the problem is about finding a balance between a reduction of wait time and its variance, POE operation costs, and the sustainment of a security level. The contribution of the dissertation is three-fold. The first uses queueing theory on the border crossing process to develop a methodology that decreases border wait times without increasing costs or affecting security procedures. The outcome is the development of the Dynamic Reallocation Methodology (DRM). Currently at the POE, inspection stations are fixed and can only inspect one truck type, FAST or Non-FAST program participant. The methodology proposes moveable servers that once a threshold is met, can be switched to service the other type of truck. Particular emphasis is given to inspection (service) times under time-varying arrivals (demands). The second contribution is an analytical model of the POE, to analyze the effects of the DRM. First assuming a Markovian service time, DRM benefits are evaluated. However, field data and other research suggest a general distribution for service time. Therefore, a Coxian k-phased approximation is implemented. The DRM is analyzed under this new baseline using expected number in the system, and cycle times. A variance reduction procedure is also proposed and evaluated under DRM. Results show that queue length and wait time is reduced 10 to 33% depending on load, while increasing FAST wait time by less than three minutes.
