Abstract: Disclosed is a positive electrode material for a lithium secondary battery. The positive electrode material includes a positive electrode active material formed of Li—[Mn—Ti]-M-O-based material including a transition metal (M) to enable reversible intercalation and deintercalation of lithium and molybdenum oxide. The positive electrode active material is coated with the molybdenum oxide to form a coating layer on a surface thereof.

Abstract: The present invention discloses a method for predicting the number of suicides using social information by considering more realistic factors such as the current environment where the individuals are frequently exposed to the social atmosphere and interact with each other with the development of the social media as well as the climate and economic conditions affecting suicides, modeling the regression analysis model by reflecting the social information such as the number of suicide-related postings posted in the social network services, the situation in which the suicide of the specific famous person is reported, and the like, and applying the social indicators such as the posting indicator, the specific person's suicide indicator, and the like to the regression analysis model to predict the number of suicides, and a device using the same.
