Abstract: A curable resin composition comprises: (I) 100 parts by weight of a curable resin; (II) 10 to 1200 parts by weight of an inorganic filler; and (III) 1 to 100 parts by weight of an organic filler having an elastic modulus of 1 to 2000 (MPa) and an average particle diameter of 0.01 to 10 ?m, wherein a content weight ratio of the components (II) and (III) is 1 to 41.

Abstract: According to an embodiment, an instructor support system has a plant simulation device used for plant operation training, an instructor support device, a dialog display device, a video device, and an operator position detection means that picks up an image of an operator with an operation detection video camera and carries out image processing for the image. The instructor support device has an operator position judgment means that judges an operator position in accordance with the information received from the operator position detection means, an operator information saving means that records a corresponding table between an ID code and an operator name, an operator name display data generation means, and an operation history display screen that shows the generated operator name display data to an instructor.
