The present invention provides a configuration to improve a heat-radiating effect of an optical subassembly having a co-axial package and a plurality of lead pins arranged in an arrayed shape. This invention also provides the materials to protect the viability of the lactic acid producing bacteria in lyophilized form and the method to prepare the composition. The apparatus further includes an air moving unit configured to draw air from the interior space of the wall into the apparatus, and a sensor configured to monitor and sample the air quality in the interior space of the wall. A date comparing unit 65, when the age of the subject is confirmed to be within a first range by an age confirmation unit 64, acquires a time difference between the capture dates of the target image data and the similar image data and compares the time difference with a second range.
