Abstract: A radiation measurement value (instantaneous measurement value) expressed by a digital value is displayed in a numeral display area of a display unit of a survey meter. A current value marker that moves in a sliding manner in the horizontal direction in accordance with the radiation measurement value is displayed in a marker display area. A history marker is displayed accompanying that current value marker. The history marker is a marker that shows the direction of change (increasing direction, decreasing direction) and extent of change of the measurement value from the past until now, and is displayed on one of one side and the other side, or both, of the current value marker. The length of the history marker shows the amount of change of the measurement value within a fixed time in the past.

Abstract: The present disclosure describes a method capable of easily and rapidly inspecting the susceptibility of bacteria or fungi to an antimicrobial drug. The inspection method of the present disclosure is a method for inspecting susceptibility of bacteria or fungi to an antimicrobial drug using a micro-device having flow channels, including: incubating a mixture of the antimicrobial drug and a suspension to be inspected in the flow channels of the micro-device; and detecting bacteria or fungi derived from the suspension to be inspected in an observation area of the flow channels of the micro-device. The detecting step can be performed by detecting an increase or decrease in the number of or a change in shape of bacteria or fungi derived from the suspension to be inspected in the observation area by a microscope or the like.

Abstract: A first calculation unit calculates a moving average (dose rate) using a relatively long averaging period (T). A second calculation unit calculates an integrated value (dose rate) using a relatively short time constant (?). In a state in which the moving average is displayed, an alarm determination unit identifies a dose abnormality on the basis of the integrated value. Within a measurement start period, a display switching determination unit identifies a constant dose rate state on the basis of the integrated value. A restoration determination unit identifies the restoration of a dose rate on the basis of the integrated value. If a dose rate is displayed using a large degree of smoothing, sudden increases, and the like, in the dose rate can be identified quickly.

Abstract: The present invention provides a novel method capable of easily and rapidly inspecting the susceptibility of bacteria or fungi to an antimicrobial drug and an inspection system for use in the method. The inspection method of the present invention is a method for inspecting susceptibility of bacteria or fungi to an antimicrobial drug using a micro-device having a flow channel, including: an incubating step of incubating a mixture of the antimicrobial drug and a bacterial suspension to be inspected in the flow channel of the micro-device; and a detecting step of detecting bacteria or fungi derived from the bacterial suspension to be inspected in an observation area of the flow channel of the micro-device. The detecting step can be performed by detecting an increase or decrease in the number of or a change in shape of bacteria or fungi derived from the bacterial suspension to be inspected in the observation area by a microscope or the like.

Abstract: L-Cysteine is produced by culturing a microorganism having an ability to produce L-cysteine and modified so that expression of emrAB, emrKY, yojIH, acrEF, bcr, or cusA gene should be enhanced in a medium to produce and accumulate L-cysteine in the medium and collecting the L-cysteine from the medium. Genes coding for novel L-cysteine-excreting proteins are identified, and utilized for breeding of L-cysteine-producing microorganism to provide a novel method of producing L-cysteine.
