Given a table image and a set of target cells, your task is to identify their positions. Represent each cell's location as JSON in the format {'value': '<cell value>', 'location': (row number, column number)}, with both row and column number begin from 1.
Refer to the values below:
CELL VALUE 1: 'World Junior Championships';
CELL VALUE 2: '5th';
CELL VALUE 3: 'release';

If a cell does not exist in the table, denote its location as 'DOES NOT EXIST'. 

The coordinates of target cells are listed below.
CELL LOCATION 1: {'value': 'World Junior Championships', 'location': (7, 1)}
CELL LOCATION 2: {'value': '5th', 'location': (5, 3)}
CELL LOCATION 3: {'value': 'release', 'location': 'DOES NOT EXIST'}
