A mounting structure of a door basket for a refrigerator is provided. According to this technique, the dummy patterns can be placed up to the area near the boundary BL between the element forming region DA and dummy region FA by placing the first dummy pattern DP1 of relatively wider area and the second dummy pattern DP2 of relatively small area in the dummy region FA. Other embodiments may generate a baseline hash of the contents of the boot locations at a first point of time and a hash snapshot of the boot locations at a second point of time, and compare the baseline hash and hash snapshot where any difference between the two hash values constitutes evidence of a resident bootkit. The browser application further presents content provided by one of the local library files via the user interface in response to the recognition of one of the local library file markup tags in the document. Both links may be simultaneously used.
