Abstract: The present disclosure proposes a system for detecting a foreign material adhering to or a scratch formed on a bevel at an edge of a semiconductor wafer in order to detect the foreign material or defect on the bevel without using a reference image and including a learning device (905) that outputs information on the foreign material adhering to or the scratch formed on the bevel as a learning result, in which the learning device performs learning in advance by using image data acquired by an image acquisition tool and the information on the foreign material or the scratch on the bevel included in the image data, and the foreign material or the scratch is detected by inputting the image data obtained by the image acquisition tool to the learning device (refer to FIG. 9).

Abstract: An object of the present disclosure is to provide a defect classification device capable of easily grasping an appropriate recipe update timing of an imaging device when classification accuracy for classifying defects existing on a semiconductor wafer is decreased. The defect classification device according to the present disclosure calculates classification accuracy by further acquiring a result of a manual classification for defects spanning a plurality of classification spaces as a result of an automatic classification, and comparing the result of the automatic classification with the result of the manual classification (see FIG. 5).

Abstract: A method for preparing serum and a serum preparation apparatus is provided that can give a large amount of serum with high culture efficiency regardless of freshness of blood used. In a method for preparing serum from blood containing at least platelets, a platelet processing step is provided in which platelet membrane in the blood is destroyed. After the platelet processing step, a deposition step for depositing thermolabile protein in blood and a removal step for removing the thermolabile protein, which has been deposited in the deposition step, are preferably provided.

Abstract: The present invention provides a separation container capable of preventing contamination with unnecessary components and efficiently separating a separation subject.

Abstract: The present invention provides a method for controlling the proliferation and differentiation of cord blood-derived hematopoietic stem cells with excellent safety when proliferating them by culturing. The hematopoietic stem cells are inoculated into a medium containing a sonicated liquid component of cord blood. The proliferation and differentiation of the cord blood hematopoietic stem cells can be inhibited in the presence of the sonicated liquid component of cord blood. On the contrary, the proliferation of cord blood hematopoietic stem cells can be accelerated by inoculating the hematopoietic stem cells into a medium containing a non-sonicated liquid component of cord blood. Thus, according to the present invention, by using serum derived from cord blood, it is possible to regulate the inhibition of the proliferation and differentiation of cord blood hematopoietic stem cells and the acceleration of the proliferation of the same as desired.

Abstract: A process for producing a porous body with different physical properties in desired regions is provided by pore forming treatment, not by bonding two or more materials made porous beforehand, with, for example, an adhesive. Raw materials are prepared, each of which contains a polymer and a raw material preparation solvent. At least two types of the raw materials having different compositions are prepared. Thereafter, the respective raw materials are frozen into desired shapes to form frozen bodies thereof. The frozen bodies thus formed are brought into contact with each other to form an assembly thereof, the assembly is exposed to a condition under which the frozen bodies begin to melt, and the assembly is then freeze-dried. Thus, a porous body having regions different in physical properties can be obtained. Such a porous body can be used as, for example, an adhesion inhibitory material or a scaffold for a cell culture.

Abstract: A separation container that can prevent the contamination with unnecessary components is provided. A separation container 1 for separating a separation subject from a sample by causing the separation subject to gather on the bottom thereof by centrifugation includes a container main body 11 and a dividing portion. The container main body 11 is a tubular container elongated in the axial direction with an upper end thereof being open and a lower end thereof being the bottom. The dividing portion has a partition 12 formed along the axial direction of the container main body, and an inner space of the container main body 11 is divided into a sample supply chamber 14 and a separation subject discharge chamber 15 by the partition 12. The sample supply chamber 14 and the separation subject discharge chamber 15 communicate with each other via a through hole 13 formed in a lower portion of the partition 12.

Abstract: A method of indirectly determining D/P creatinine for easily judging a peritoneal function is provided that does not require blood sampling or multiple recoveries of dialysis effluent. The method includes preparing a dialysis effluent obtained by peritoneal dialysis, measuring at least one protein marker selected from the group consisting of prealbumin, haptoglobin, alpha 1-microglobulin, C4, and total protein that are contained in the dialysis effluent, and determining D/P creatinine indirectly from the correlation equation that represents the relationship between the marker concentration and the D/P creatinine value that has been prepared beforehand. Furthermore, the PET category is determined indirectly from the D/P creatinine, which has been determined indirectly, based on the known reference value.
