How to use non static field in static member?

I have an Event manger with static members. The static members will update scores, sound and such.
The problem is I need to update the text of UI text field which is public only. Of course this will throw an non static member error. How do I get around this?

public class EventManager : MonoBehaviour {

        public delegate void DieAction(GameObject obj);
	    public static event DieAction OnDie;
        public Text score;
        public static int scoreCount = 0;

        public static void DieDispatch(GameObject obj)
	   {

		if (obj.tag == "coin")
		{
           
                  //play sound, add score etc....
                 score.text = "SCORE:" + scoreCount.ToString();

		}


		if (OnDie != null)
		{
           
                    //event for anybody subscribing
			OnDie(obj);

		}

	}

}

Look into the Singleton design pattern.
