Abstract: A telework effect prediction apparatus (100) includes a storage unit (110) for storing a telework effect prediction model (111) for predicting a degree of effectiveness of teleworking based on a congestion degree of a commuting route and a cooperative work amount of a user, an acquisition unit (120) for acquiring a predicted value of the congestion degree of the commuting route of a specific user on a designated date, a calculation unit (130) for calculating a cooperative work amount from a work schedule of the specific user on the designated date, a prediction unit (140) for predicting the degree of effectiveness of the teleworking from the acquired predicted value and the calculated cooperative work amount by using the telework effect prediction model; and an output unit (150) for outputting information based on the predicted degree of effectiveness.

Abstract: A method of manufacturing cold rolled steel sheets for extra deep drawing is disclosed, which comprises the steps of:melting and continuously casting a steel material containing not more than 0.0060% of C, 0.01 to less than 0.10% of Mn, 0.005-0.10% of Al, Ti corresponding to Ti(%) of the following equation (1) when an effective Ti amount expressed by Ti* in the formula (1) satisfies the following inequality (2), and optionally, 0.005.about.0.2% in total of at least one of Cu, Ni and Cr to obtain a cast slab;hot rolling the cast slab immediately or after the slab is heated at a temperature of 900.degree.-1,150.degree.
