Abstract: Provided is a program for a game where a plurality of ally characters and an enemy character are made to battle with each other, the program causing an electronic device to execute: determining whether the enemy is in a special-attack target state where the enemy becomes a target of a special attack; setting the allies disposed within a predetermined range of the enemy in the game field, in a state of being able to execute the special attack, if in the special-attack target state; allowing the allies to execute the special attack in the state of being able to execute the special attack; determining whether the executed special attack succeeded; increasing correction points when the special attack succeeded; decreasing the correction points according to a period during which the correction points are not increased; and correcting parameters associated with the allies when the correction points satisfy a correction condition.

Abstract: A steel having few alumina clusters prepared by casting liquid steel deoxidized with Al, with the addition of one or more rare-earth metals (REM) selected from the group of Ce, La, Pr and Nd in which: (a) The REM-oxide-content in oxide-based inclusions consisting mainly of alumina and REM-oxides is 0.5 to 15 mass % of said oxide-based inclusions, or (b) The mass ratio of total REM to total oxygen (T.O.), REM/T.O., in liquid steel is not less than 0.05 and not more than 0.5, in addition to (a), or (c) The total REM-content is not less than 0.1 ppm and less than 10 ppm and the dissolved-REM-content is less than 1 ppm.
