Abstract: The information processing apparatus includes a display. The information processing apparatus accepts user operations via a GUI (graphical user interface) displayed on the display. When the service ends, the forgotten item notification screen is displayed on the display. In the forgotten item notification screen, a forgotten item reminder unit is provided for reminding a user who left behind a reminder target item, including the property of the user used in connection with the service. An individual reminder section is provided in a forgotten item reminder unit, to give an individual reminder to prevent the occurrence of leaving behind of each reminder target item, for a first-type item for which retrieval cannot be detected and a second-type item for which retrieval can be detected but which has not been retrieved, from among the reminder target items.

Abstract: The information processing apparatus includes a display. The information processing apparatus accepts user operations via a GUI (graphical user interface) displayed on the display. The operation screen is displayed on the display. On the operation screen, an operation guidance portion, including a message for providing operation guidance to the user, and a plurality of operation keys for accepting user operations are displayed. A part of the operation guidance portion is colored in a first color, the operation keys which are the first type of operation key are colored in the first color, and the operation keys which are the second type of operation key are not colored in the first color.

Abstract: A method for preparing foreign protein in yeast using an expression recombinant DNA comprising DNA encoding the serum albumin signal peptide adjacent to DNA encoding the foreign protein is disclosed.

Abstract: Novel signal peptides capable of functioning in yeasts have the amino acid sequence:Met-A.sub.1 -A.sub.2 -X-B-C-D-E-Fwherein A.sub.1 is a peptide chain composed of 1-3 amino acids each selected from the group consisting of Arg, Ser, Lys and His, A.sub.2 is a peptide chain composed of 1-3 amino acids, X is a peptide chain composed of 8-10 hydrophobic amino acids, B is Pro or Ser, C is Gly or Pro, D Cys, Ala, Leu, Ser, Thr and Val, E is Trp or Gln and F is Ala or Gly. DNA sequences coding for these signal peptides can be used for the secretory expression of heterologous proteins in yeasts.

Abstract: Alkaline protease which has leucine or isoleucine in the place of valine at the amino acid number 40 of wild type alkaline protease, a gene encoding the amino acid sequence of alkaline protease which has the substitution as described above, a recombinant DNA comprising said gene, a method of producing the above described alkaline protease, and a DNA fragment used for the expression of a gene.
