A method for modeling task, activity and workload of various human-implemented processes. The said illuminated object including all kind of seasonal lighting, regular light fixture, track light, desktop light, battery operated light which has more than one piece of light-units or LED-units. The computing system retrieves the target model and elements of the target model. For this method, there is provided a cell for infrared absorption spectroscopy measurement thereof is carried out to thereby identify the concentration of silanol groups in the silicon compound. The compound used as an active ingredient in the pharmaceutical composition of the present invention suppresses VEGF-induced angiogenic responses without cytotoxicity at a low concentration by inhibiting the expression of an anti-angiogenic factor, and thus remarkably improves the safety of a drug.
