In recent years, marine natural products in drug development increasingly wide range of applications. Both Taiwan's geographical location and climate are creating a rich marine biodiversity. Hence there is needed to construct a marine natural product database which with Taiwan features. The goal of this study is to establish a Taiwan's marine natural product database, with preliminary collected Formosan soft coral diterpenoids natural products from Taiwan for drug development features. The database included normal physical and chemical properties of compounds and biological activity assay from literature. Key project for the database is to construct three-dimensional structure information for marine natural products. In this study, it was to build and to check the correct three-dimensional structure by use of computer simulation study comparing with nuclear magnetic resonance (NMR) spectroscopy information from literature. The identification of the folding errors in three-dimensional structure of various compound skeleton types by computer was also discussed. And there was also discussed the relationship between potential energy and three-dimensional structure of compounds by compare with computer simulated structure and NMR structure.

The Pliocene-Recent Muda formation is essentially undeformed in the West Natuna Basin, and excellent resolution of this interval on three-dimensional seismic data in Belida Field allows detailed interpretation of component fluvial-deltaic systems. Detailed interpretation of seismic time slice and seismic sections along with seismic facies analysis, horizon mapping, and extraction of seismic attributes provide the basis to construct a sequence stratigraphic framework and determine patterns for sediment dispersal and accumulation. The Muda interval contains five third-order sequences, with depositional environments confined to the shelf and consisting mainly of fluvial elements. Sequence boundaries (SB) apparently result from major sea level falls, since there was no tectonic uplift and the field underwent only regional slow subsidence during sedimentation of the study interval. Sea level fluctuation also caused changes in fluvial patterns. Analysis of changing channel patterns indicates that major systems tracts relate to specific channel patterns. The Lowstand Systems Tract (LST) is generally dominated by larger channel dimensions and low sinuosity channel patterns. The Transgressive Systems Tract (TST) typically contains relatively smaller channels with high sinuosity. Channels in the Highstand Systems Tract (HST) generally show moderate sinuosity channels and are intermediate in size, larger than TST channels but smaller than LST channels. Crossplots of stratigraphic position and channel morphology indicate that within the transition from LST-TST, channel dimensions (width and thickness) generally decrease and channel sinuosity generally increases. High sinuosity, meandering and anastomosing channels are generally found near the maximum flooding surface. Low sinuosity channels occur within the HST-SB-LST succession, with the exception of higher sinuosity meandering channels evolving inside valleys. Larger, lower sinuosity channels result from high gradient and high discharge associated with stream piracy. Smaller, high-sinuosity channels result from low gradient and small discharge. Extraction of seismic attributes such as RMS Amplitude and Average Reflection Strength show these depositional features in greater detail. In the Belida Field area, lowstand channels were found to comprise the greatest volume of sandstone bodies. Seismic delineation of the distribution and morphology of these channel systems provides critical input for reservoir modeling and volumetric analysis.

A three dimensional numerical model for a micro proton exchange membrane fuel cell was developed to simulate the concentration distribution of the fuel gas, and analyze the flow field and current field in the fuel cell. Finite control volume scheme with SIMPLEC algorithm was employed in the numerical method. Various operating conditions on the performance of the fuel cell were studied. It was shown that the concentration of oxygen at the cathode can strongly influence the cell performance. Increase the operating temperature and the pressure of the inlet gas can improve the performance of the fuel cell.
