E-learning plays a key enabling role in knowledge management for individuals, schools, and enterprises. Nevertheless, the lack of standards in content and learning management systems (LMSs) makes the reusability and interoperability of learning resources infeasible. The emergence of the SCORM specification has shed light on the standardization of(More)
Four new endiandric acid analogues, tsangibeilin C (1), tsangibeilin D (2), tricyclotsangibeilin (3) and endiandric acid M (4), one new lignan, beilschminol B (5) and two new sesquiterpenes, (+)-5-hydroxybarbatenal (6) and (4R,5R)-4,5-dihydroxycaryophyll-8(13)-ene (7), together with four known compounds (8-11), were isolated from the roots of Beilschmiedia(More)
Since the emergence of the SCORM specification, e-learning has received more and more attentions in recent years. It plays the key-enabling role in knowledge management for individual, schools, and enterprises. The most salient features of SCORM come from its goal, namely, reusability, accessibility, interoperability, and durability. One of the underlying(More)
Fractionation of an EtOAc-soluble fraction of the solid fermentate of an endophytic fungus, Lachnum abnorme Mont. BCRC 09F0006, derived from the endemic plant, Ardisia cornudentata Mez. (Myrsinaceae), resulted in the isolation of three new chromones, lachnochromonins D-F (1-3), one novel compound, lachabnormic acid (4), along with nine known compounds(More)
Two new triterpenoids, 2α,3β-dihydroxyolean-11,13(18)-dien-19β,28-olide (1) and 3β,5β-dihydroxyglutinol (2), together with eight known compounds (3-10) were isolated from the roots of Rhaphiolepis indica var. tashiroi (Rosaceae). The structures of 1-10 were determined by spectroscopic techniques. Among these isolates, 2α,3β-dihydroxyolean-13(18)-en-28-oic(More)
The emergence of the SCORM specification has shed a light toward standardization of e-learning which makes the reusability and interoperability of learning resources feasible. However, the existing SCORM-compliant asset model is oversimplified ; only few asset types are defined. On the other hand, W3C's declarative-style SMIL is becoming prevalent in(More)
