When the nucleic-acid base sequence of A, C, G, and T (or U) is determined by interpreting fluorescent-light intensity waveform data acquired by measuring nucleic-acid fragments, it is desirable to determine, with a high-accuracy, the base sequence at a location at which the data interpretation is difficult. In order to accomplish this object, the data interpretation is performed by making reference to information acquired by performing the statistical processing to plural pieces of fluorescent-light intensity waveform data corresponding to already-known base sequences. This method allows the determination of the nucleic-acid base sequence at the above-described location.

There is provided a process analysis method capable of clustering of executed processes and extraction of similar processes. A process analysis method of the present invention converts the similarity between processes into a numeric value as a metric by including a process matrix transformand a metric calculationfor process recordsmade up of a series of records of rendered service of at least three elements of the time of service, the type of service, and the quantity of service. This enables the calculation of the similarity between processes as a metric from information of only a series of records of rendered services. Accordingly, it becomes possible to cluster the executed processes and to extract similar processes based on the metric herein calculated.

It was difficult for previous health management support systems to grasp daily health condition quantitatively through using comprehensive indexes of personal health conditions, optimize advice as healthcare guidance, and show its expected effect in a favorable way. The disclosed method and system implement the following: estimating a predicted period of healthy life expectancy of each person who underwent health screening from health screening report data obtained through the health screening report data entry step, wherein healthy life expectancy prediction data is used that is prepared as basic data for predicting healthy life expectancy from a diversity of health screening report data. The predicted period of healthy life expectancy and related information for each person are displayed by display means or printed out by printing means.

In a place where the personal authentication is requested, if there occurs an emergency, e.g., an authenticatee is forced to unlock a key under threat against the authenticatee's will, there is provided an urgency report system that has lowered both a danger of an authentication apparatus's false operation and a risk of being detected from those around the authenticatee. In the personal authentication technology based on a finger-vein authentication, the employment of the following methods makes it possible to enter a rescue mode and to issue an urgency report: Actively deforming the finger-vein pattern in captured image, pushing a switch, which becomes a trigger for starting the authentication, longer than a predetermined time, or using a rotational motion of the finger.

In a bacteriological examination system, an expected range of drug sensitivity is calculated from the results of statistics of data acquired at past drug sensitivity tests. Testing panels accommodating drugs of different densities (ex. increasing by increments) covers the calculated expected range are selected for testing. An average-per-sample value of drug sensitivities of bacteria that reside in a hospital and an average-per-sample value of drug sensitivities of bacteria that reside in a limited region are preserved separately in a results-of-test database. A difference between statistical values of drug sensitivities of one bacterial species in a bacterial classification group residing in a hospital to an object drug and statistical values of drug sensitivities of the bacterial species residing in a limited region is calculated. The difference then is divided by the average-per-same value in the limited region. An average-per-bacterial species value is then obtained by averaging the difference-division values of the involved species to obtain a drug fastness index relative to the object drug.

A health checkup supporting method, apparatus and computer readable recording medium for predicting a checkup receiver's risk of suffering from a disease. The method and apparatus include inputting checkup receiver information indicating information showing the possibility of affecting the incidence of a disease obtained with respect to a checkup receiver who has received a health checkup, and finding a value of a risk of the checkup receiver's suffering from the disease based on the inputted checkup receiver information and risk parameters obtained from a ratio of the past checkup receivers' suffering from the disease. The checkup receiver information includes results of at least one of a clinical examination and results of a genetic examination conducted with respect to the checkup receiver.

An annotation command data for annotating a displayed image is in the form of an original data block having a first data area holding an initial state for the displayed image and a second data area holding one or more commands and a starting time point of execution for each of the commands. Execution of each command is started at its associated starting time point of execution. For editing of the annotation command data, the original data block may be divided to produce therefrom plural secondary data blocks each having an initial state, a part of the one or more commands and a starting time point of execution for each of the part of the commands, so that one of the secondary data blocks is deleted, or a new data block having an initial state, one or more commands and starting time point of execution therefor is inserted between the secondary data blocks.

In a health checkup supporting method for predicting a health checkup receiver's risk of suffering from a disease, steps are provided to input checkup receiver information indicating the possibilities of a disease being contracted by a checkup receiver and to obtain a risk value indicating a degree of the checkup receiver's possible incidence of the disease based on inputted checkup receiver information and a risk parameter obtained from the ratio of past disease patients.

Recognizable data storage apparatus stores an image feature parameter of an object and its classification result for those objects for which said classification results are evaluated as having high reliability and recognizable and for which a classification result is outputted by first pattern recognition apparatus, and recognition suspension data storage apparatus stores an image feature parameter for those objects for which said classification results are evaluated as having low reliability and as being suspended from recognition. Pattern recognition method constitution apparatus constructs second pattern recognition apparatus on the basis of the classification result stored in the recognizable data storage apparatus, and re-classification is conducted for those objects recognition of which is to be suspended. A neural network, for example, is used for the second pattern recognition apparatus. Wrong classification of objects due to an individual difference can be reduced and automated pattern recognition having high accuracy without depending on an individual difference can be accomplished.

A logical operation circuit in which wiring as generally performed between transistors is made unnecessary to improve reliability, stability and integration degree of a logical circuit using a tunnel phenomenon, for example, a single-electron tunnel phenomenon, or a flight phenomenon of a particle group. Conducting materials are arranged in a two-dimensional plane or three-dimensional space in the logical circuit. When two conducting materials are arranged to be nearest each other, the two conducting materials are connected, for example, by a single-electron tunnel phenomenon. When two conducting materials are arranged to be not nearest, there is no connection between the conducting materials by the tunnel phenomenon. Propagation of electrons is controlled by changing the arrangement. Further, because particles which have entered input regions move toward different flight directions respectively from a branch region on the basis of the property that two particles cannot enter simultaneously within an effective scatter distance by repulsive interaction between particles, flight of particles is controlled so as to enter or not branched particles into an observation region to thereby construct a wiringless logical operation circuit.

Wiringless logical operation circuits

A silicon wafer having a tungsten and/or molybdenum film formed on its surface is heat-treated in hydrogen containing water vapor. Thus, silicon can be selectively oxidized without substantially oxidizing tungsten and/or molybdenum.
