A method of managing system health is provided. The method includes calculating a reconstruction missing value with respect to the second domain data, determining a degree of degradation of the system on the basis of the reconstruction missing value, predicting a second remaining useful life (RUL) prediction value {tilde over (y)} of the system on the basis of the second domain data, based on a result of the determination of the degree of degradation, optimizing a degradation compensation function on the basis of a distribution of a first RUL prediction value y of the system predicted based on the first domain data in a pre-learning process of the diagnosis model, and predicting a final RUL prediction value {tilde over (y)}' obtained by compensating for the second RUL prediction value {tilde over (y)}, by using the optimized degradation compensation function.

A mixed reality content providing apparatus is disclosed. The mixed reality content providing apparatus may recognize an OOI included in a 360-degree VR image to generate metadata of the OOI and may provide a user with mixed reality content where the metadata is overlaid on the 360-degree VR image.
