Tapeng Bay is the second largest lagoon in Taiwan. The biological and ecological environments are an autotrophic system and are influenced by seasonal variability, terrestrial pollutant inputs and the exchange rates with seawater. There¡¦re intense oyster culture and fish farming activities in the bay before July, 2002. The oyster was the most important spineless member in the lagoon. They would filtrate microplankton and detritus; they would also excrete nutrient and consume dissolved oxygen. Therefore, oyster played a very crucial role in the Tapeng Bay. This study combines the biological responses of the oysters with the complicated interaction among microplankton, nutrient, detritus and dissolved oxygen to establish the relationship of dynamical mechanisms between variables by applying the system dynamics simulation software STELLA. Model results clearly reveal that the oysters are the main species of filtration. The factors which affect the biomass of oysters include microplankton concentration, temperature and individual mass; the connection between oysters and other biological variables is closely tied. The study has also shown that the removing of oysters may cause significant increases of plankton and detritus during the eutrophication condition. Although the simulated water quality variables show higher than those obtained from sampling experiments in the literatures, the trend corresponds well with the relative studies. Despite the fact that oysters excrete much nutrient and nutrient is mostly taken up by microplankton, the condition of nutrient limitation has never happened, which is in correspondence with the result. In the sensitivity analysis, the parameters of oyster filtration rate and the autotroph nitrogen to carbon ratio are important factors which have influence on oysters biomass, and the concentration of microplankton and ammonium. Oyster excretion rate and the proportion of oyster feces and pseudofeces also have significant influences on the concentration of ammonium. The oyster culture racks in the Bay have already been torn down, but the Bay is still eutrophic. This is a clear indication of the importance of the oysters in the lagoon. Properly culture some oysters in the area where exist high concentrations of microplankton or organic input. By applying the oyster abundant filtration, planktons and suspended solids, mostly detritus and organic matters, can probably be controlled and the water quality in the bay can thus be improved. Although the STELLA has its limitation on broader applications, the model developed by this study can be combined with the features of social or economic fields. A decision supporting system can be developed for the management of ecological environment policies.

The objective of the submitted thesis is to work out the financial analysis of the selected business subject. In the first part of the thesis, time aspects of the financial analysis are examined. Time aspect comparison consists in values developement in particular ratio indices within 5 years term. In the following part of the thesis, financial models of plant and livestock production are introduced, using simulation programme Stella. In these kinds of production, development of monthly income and cost balance is observed. On the basis of financial analysis, particular measures for the improvement of the economic condition in the selected company are proposed.

Stella Jones Gallery: An Organizational Analysis and Suggested Marketing Plan is based on my internship as Managing Director of Stella Jones Gallery. The internship report will focus on 1. Analyzing the organizational structure and cultures of Stella Jones Gallery as it relates to the internship and 2. Creating a marketing plan to support, expose, and expand the mission of the organization. Because of the report's objectives, the internship report has been segmented into the following sections: Part I: Organizational Analysis Stella Jones Gallery's organizational structure and culture will be analyzed to determine the effectiveness and efficiency of its methods and practices. Through the analysis, a description and evaluation of my internship as Managing Director will be provided to discuss the overall effectiveness of the position. It will also discuss the position's contribution to the strengths and weaknesses of the organization. This section will be immediately followed by suggestions in management and staffing as well as ways in which the organization can redefine and strengthen its organizational culture. Part II: Suggested Marketing Plan At the time of the internship, Stella Jones Gallery had been in existence for three and a half years and is emerging as one of the leading African-American galleries in the southeast region of the United States. The gallery has been very fortunate to have reviews in highly regarded magazines such as Art Business News, Art and Antiques, and the International Review of African-American Art. It has not, however, established a strategic marketing plan to propel the gallery to the forefront of the commercial arts industry. The marketing plan created will suggest ways the gallery can capitalize on the medial attention it has received. Secondly, it will illustrate how the gallery can promote and establish its product within the commercial arts industry and non-profit sector of the visual arts. Finally, it offers ways in which the gallery can forge ahead of its competition by offering on-line as well as curatorial and educational services. The issues addressed and suggestions made are to help Stella Jones Gallery reach its potential as a leading art organization. In conclusion, this report will note any changes or improvements made in the gallery's management practices, staff, and marketing strategies as a result of the suggestions offered.
