A Study on the developmental tendency and strategy of Free Trade Zone ----Taking Kaohsiung Port for Example

Wu, Jeng-yang 31 January 2008 (has links)
Develop rapidly day by day along with economic trade system in the world, our country continuously looks for economic trade system and the way of improvement of system, with this promote our country is in the global economic trade system of competition ability. The region in Taiwan belongs to an island type nation in Pacific Asia region, it mainly trades contacts and import and export homework to still regard sea transportation conveyance as principle, and past results of the port homework and operation role also seem to be more important. Continuously developing in newly arisen port in all countries now is rising, how face port to quickly change and circulating of each industry trade, will be the main topic that promotes our country competitive advantage. Ports run by private capitals is now the world trend. This research summed up the future development of every international business port in Taiwan, and took Kaohsiung port as an example to explore the effects and achievements after the implementation of free trade zone. Because the policy of free trade zone has been implemented for a period of time in the neighbor countries of Pacific Asia, this study aimed to explore the definition of free trade zone as well as compare the similarities and differences of its implementation in other free trade zones in the world. According to the characteristics of free trade zone establishment, this research also analyzed the superiority and inferiority which Kaohsiung port encountered at the moment. Related strategies and suggestions were provided to enhance Kaohsiung port¡¦s competitiveness in Pacific Asia region based on the implementation and outcome of Kaohsiung Free Trade Zone. The findings were discussed and draw a conclusion as follows: 1) Kaohsiung port zone should develop the character of outside custom inside territory and create re-export business due to its limit interior region. 2) Accelerate to develop outside port zone, and set up value-added logistics port. 3) Cultivate professional sales managements; enhance effects on attracting and spreading business iii 4) Promote One-stop Window (Customer Service) to circulate goods freely inside the zone.

Developmental and reproductive regulation of NR5A genes in teleosts

Hofsten, Jonas von January 2004 (has links)
<p>In mammals sex chromosomes direct and initiate the development of male and female gonads and subsequently secondary sex characteristics. In most vertebrates each individual is pre-destined to either become male or female. The process by which this genetic decision is carried out takes place during the embryonic development and involves a wide range of genes. The <i>fushi tarazu</i> factor-1 (FTZ-F1) is a nuclear receptor and transcription factor, which in mammals has proven to be essential for gonad development and directs the differentiation of testicular Sertoli cells. A mammalian FTZ-F1 homologue subtype, steroidogenic factor-1 (SF-1), is a member of the nuclear receptor 5A1 (NR5A1) group and regulate several enzymes involved in steroid hormone synthesis. It also regulates the expression of the gonadotropin releasing hormone receptor GnRHr and the β-subunit of the luteinizing hormone (LH), indicating that it functions at all levels of the reproductive axis. Another mammalian FTZ-F1 subtype, NR5A2, is in contrast to SF-1, not linked to steroidogenesis or sex determination. Rather, NR5A2 is involved in cholesterol metabolism and bile acid synthesis in liver. Hormones and environmental factors such as temperature and pH can influence teleost development and reproductive traits, rendering them vulnerable to pollutants and climate changes. Very little is known about teleost FTZ-F1 expression, regulation and function. In this thesis, expression patterns of four zebrafish FTZ-F1 genes (ff1a, b, c and d) and two Arctic char genes (acFF1α and β) were studied during development, displaying complex embryonic expression patterns. Ff1a expression was in part congruent with expression of both mammalian NR5A1 and NR5A2 genes but also displayed novel expression domains. The complexity of the expression pattern of ff1a led to the conclusion that the gene may be involved in several developmental processes, including gonad development, which also was indicated by its transcriptional regulation via Sox9a. Two ff1a homologues were also cloned in Arctic char and were shown to be involved in the reproductive cycle, as the expression displayed seasonal cyclicity and preceded that of the down stream steroidogenic genes StAR and CYP11A. High levels were correlated to elevated plasma levels of 11-ketotestosterone (11KT) in males and 17β-estradiol (E2) in females respectively. Treatment with 11KT did not affect FTZ-F1 expression directly but was indicated to alter expression of CYP11A and 3β-hydroxysteroid dehydrogenase. E2 treatment was indicated to down-regulate the expression of testicular FTZ-F1, which may contribute to the feminising effect previously observed in E2 treated salmonids. Ff1d is a novel FTZ-F1 gene, expressed in pituitary and interrenal cells during development, suggesting steroidogenic functions. In adult testis and ovary ff1d was co-expressed with anti-Mullerian hormone (AMH), a gene connected to sex determination in mammals and previously not characterised in teleost fish. The co-expression between ff1d and AMH was found in Sertoli and granulosa cells, which is congruent with the co-expression of mammalian SF-1 and AMH. This suggests that ff1d and AMH may have similar functions in teleost sex differentiation and reproduction, as their mammalian homologues. In conclusion, this study present data that connects members of the teleost FTZ-F1 family to reproduction, cholesterol metabolism and sex determination and differentiation.</p>
