Transact SQL :: HierarchyID - How To Give A Column Name For Node Path

I just started learning HierarchyID and copied the the following code from [URL] .... and Chapter 7 Hierarchical Data and the Relational Database of the book "Programming Microsoft SQL Server 2012", written by L. G. Lobel and A. J. Brust (Published by Microsoft Press):

-- shcHierarchyid_1.sql
-- 19 August 2015 13:15 PM

USE master
GO
IF EXISTS(SELECT name FROM sys.databases WHERE name = 'shcDB')
DROP DATABASE shcDB
GO
CREATE DATABASE shcDB
GO

[Code] ....

I executed the code in my Microsoft SQL Server 2012 Management Studio (SSMS2012).  It worked nicely. But, I don't understand the following 2 things:

#1: In the Results, I got:          

(No column name)     Position    Title
                1       /          CEO
                2 /1/         0x58      Purchase Manager
                3      /1/1/         0x5AC0 Purchase Executive
                4      /2/             0x68       Sales Manager
                5 /2/1/         0x6AC0  Sales Executive

I don't know how to give a column name for the /, /1/, /1/1/, /2/, /2/1/ (NodePath (?) I guessed). How I can give a column name to that column.

#2:   The book lists "USE master  GO .....".  I wonder whether I can do the "hierarchyid" thing in the private database I created!!??  Whether I can do the "hierarchyid" thing in the private database or not.
