Title: Information processing program, information processing method, and information processing apparatus
Inventor: MAEDA TAKAAKI
IPC: G06F16/383
Filed: 2020-02-17
Abstract: To enable a shared file which a user should access to be presented to the user.SOLUTION: An information processing apparatus detects a state of access to shared file shared by a plurality of users in a group, and determines, based on the access state, which shared file each of users having a shared folder list 160 including the shared file should access. The information processing apparatus generates the shared folder list 160 including display of presence of the shared file the user should access and presents it to the user. For example, if a user opens the shared folder list 160, the information processing apparatus determines, based on the number of accesses to the shared file and so on, that a newly created shared file 162a and a shared file 162b updated a predetermined number of times or more are shared files to access. The information processing apparatus additionally displays an access candidate folder 161 in the shared folder list 160 and expressly presents presence of the shared files 162a and 162b to the user.SELECTED DRAWING: Figure 7

Abstract: To perform stable measurement with high sensitivity when sensing an object to be sensed in sample liquid based on the oscillation frequency of a piezoelectric vibrator.SOLUTION: A core member 71 is disposed on one side of a piezoelectric piece of a sensing sensor and a piezoelectric vibrator before supplied with sample liquid is oscillated to measure the oscillation frequency. Next, the sample liquid is supplied to one side of the piezoelectric piece having the core member disposed thereon, and while maintaining the state in which the sample liquid is attracted around the core member due to the surface tension acting between the sample liquid and the core member, the sample liquid is dried and removed. After the sample liquid is dried and removed in this way, the piezoelectric vibrator is oscillated to measure the oscillation frequency. Based on the frequency difference between the oscillation frequency before the sample liquid is supplied and the oscillation frequency after the sample liquid is dried and removed, the adsorption of an object to be sensed onto an adsorption region formed on the piezoelectric piece is sensed.SELECTED DRAWING: Figure 5
