Task was changed by little but problem stays active. 
I have code below this is responsible to display records of user with ID 164, but as you can see I have added ID of user manually into code. So it displays for everyone records from this user. 
But I want to add variable on 
line 6 where is written 
164 which will display 
ID of user who is viewing this module, so he will see own records and not users with ID 164. 
if($params->get('view_what', 'all') == 'author')
{
	$query = $db->getQuery(TRUE);
	$query->select('id');
	$query->from('#__js_res_record');
	$query->where('user_id = 164');
	$query->where('published = 1');
	$query->where('hidden = 0');
	$query->where('section_id = ' . $params->get('section_id'));
	$db->setQuery($query);
	$ids = $db->loadColumn();
	if(empty($ids))
	{
		return;
	}
	$params->set('view_what', 'all');
}
