Smartphone, Ultrabook and Tablet PC put close the distance between human and computer device. But there are many users who can't use that Personal Digital Assistant efficiently. They need to improve its operability. Intelligent agent system has been attracting attention to solve such a problem. In order to develop intelligent agent system, it is necessary to improve the recognition rate of a text conversation for these users. In this paper, we propose a mathematical model for estimating the sentence patterns from the word order of conversation text (in Japanese). We use Hidden Markov Model (HMM) to affiliated labeling for estimating the sentence patterns from the word order of Japanese conversation text. A sentence is composed of a sequence of attributes and basic components as subject, verb, and adjective. Thus we can infer stochastically word order of basic components from pattern of postpositional in the text. We are trying to affiliate labeling Japanese conversation text using HMM. In this study, Two models, the model containing both the sentence which does not contain a subject, and the sentence containing a subject, and the model of only the sentence which does not contain a subject, were prepared, and comparative experiments were conducted.

Main purpose of our study is to develop an Android application that can support crippled person to communicate with others using the smartphone. Crippled person who cannot communicate by oral use computers or mobile phones to communicate with others. Many of them use a mobile phone which Autoscan mounted and has an external switch such as the touch sensor, not a general one. However, for reasons that stop production of this special terminal, it is very difficult for them to buy it nowadays. Therefore, the smartphone has been mentioned as a candidate for an alternative terminal. But maintenance of accessibility is not sufficient yet. We have developed a software keyboard which has Autoscan and one touch input system that can be entered easily by them. In this article, we have selected the Japanese as the main language for the input system and have developed some software keyboards. We tested this developed Android application. In the paper, we also show formulas for the index of ease of input in order to examine the results of the experiment. Taking into the results of these experiments, we have examined the settings for building an environment friendly according to the user input. We would like to extend the functionality of the software keyboard and consider the requirement of features for futures studies.

Medication compliance of long-term drug therapy outpatients is poor because of low-frequency visit of the patients to clinic and dispensing pharmacy. This is also because that their subjective symptoms are not straightforward. Recently a crane truck driver who has epilepsy hit and killed six of children in an accident. A crane truck driver is epilepsy patient and forgetting to take medicine is suspected to be cause of the accident. In this research, we design support system for long-term medication patients to improve medication compliance, for use in dispensing pharmacy. In the proposed system, the patient operate simulation of own symptom implemented on computer, corresponding to the medication status such as "took" or "not took" drug, every dosing time. The patient has subjective symptom by seeing change in his symptom through the simulation on the computer. The status of the patient medication is sent to the computer of pharmacist in the dispensing pharmacy, pharmacist in charge watch the status of his patient medication status. The pharmacist can utilize the medication status report for drug administration guidance when the patient visits to the clinic and the dispensing pharmacy next time. Through using of the proposed system, the patient improves his medication compliance and adherence.

Recently, the research of the cognitive function of the brain has been developed and applied to the cognitive rehabilitation frequently. Attention process training has been introduced as cognitive rehabilitation for the improvement of the attention function that is the base of the cognitive function. And Modified attention process training (M-APT) has been used as a Japanese version usefully. The reports say M-APT has improved not only the attention function, but also the motivation and the social extroversion. The author performed the activation training of the attention function of the cerebrovascular disease patients, and examined what influence the improvement of attention function gave to the language function, communication skills and the intelligent function. The author examined the cards classification problem in M-APT on eight cerebrovascular disease patients (four men and four women), and trail making test-A 'B, standard language test of aphasia, the communication ADL test and mini-mental state examination were performed before and behind the cards classification problem. The results of each evaluation of the cards classification problem were analyzed in statistics. As a result, the attention function, the language function and communication skills have improved respectively before and after the attention activation training. The attention function is a base of all the cognitive ones. The improvement of the attention function has a great influence on the language function and communication skills were suggested. It is necessary to examine more cases and devise the research method furthermore.

According to the auditory filter theory, it has been known that the basilar membrane of the cochlea in the inner ear is, for example, modeled as 24-channel filter array. Because the passing bandwidths of the nonlinear filters dynamically vary in response to an input sound or vibration, there is room for verification on our proposed acoustic model, in which a waveform with an one-octave passband is reconstructed by the linkage of sinusoidal curves between successive extrema. In this study for 1-h speech and music recordings, we have evaluated the effects of spectral bandwidths, interpolation curves, and the least-squares estimation of extrema, using the normalized squared-error between an original waveform and the reconstruction. Firstly, the difference errors for an one-octave waveform remain at less than 1.2 percent, compared with the narrower filtered waveforms. Secondly, the error of the sinusoidal interpolation is the least among other five methods with transcendental functions, in agreement with our previous studies in terms of the subjective score as well as the objective quantification with event-related potentials. Thirdly, the original waveform is identical to the reconstruction with the extremal estimation below 1,280 Hz, and moreover with leveling minima below mere 160 Hz, suggesting the conservation of the sound quality despite ambiguity in shape.

The present study considers a fuzzy color system in which three membership functions are constructed on the color triangle. This system can process a fuzzy input to a color triangular system and output the center of gravity of three weights associated with respective grades. Three input fuzzy sets (red, green, and blue) are applied to the color triangle relationship. By treating three attributes of redness, greenness, and blueness on the color triangle, a target color can be easily obtained as the center of gravity of the output fuzzy set. In the present paper, 0% triangle is consisted of three lines of 0% redness, 0% greenness, and 0% blueness of the attributes. The colors on 0% triangle map into the right corner of tone triangle (on chroma C or near C). As compare the inference results for fuzzy inputs with those for crisp inputs, move to W (white region). The input-output relationship is shown by redness and chromaticness. The inference outputs for crisp inputs and for fuzzy inputs are roughly similar in this case. However at 0% triangle inference outputs are obviously different. Those for crisp inputs show vertically linear.

HIV virus grows early after infection. After HIV virus grows to some extent they are suppressed by the action of the immune system. However, the immune system cannot annihilate HIV virus, they explosively grow finally through long incubation period (about 10 years). However, no one knows the cause of such specific behavior of HIV virus. Various mathematical models have been proposed. But all models couldn't explain the behavior. We think that passing over macrophages caused their failures. In this paper, we propose a mathematical model taking the macrophage into account. As a result we succeed in reproducing the specific behavior of HIV virus.

This paper shows the pitchfork bifurcation arising in the Fisher-Kolmogorov(F-K) equation with the theta logistic model in the context of the dynamical systems. Studies of the F-K equation have mainly focused on the travelling waves so far. In the original paper of Fisher, p(the frequency of the mutant gene) and q(the frequency of its parent allelomorph) are presented by such a differential equation as a diffusion equation with the logistic model. We consider the theta logistic model on the F-K equation. Using the multi-scale analysis, the pitchfork bifurcation occurs when the sign of the growth rate of the theta logistic mode changes from minus to plus.

In recent years, development of interactive artificial intelligence is remarkable, but there are few models that can be human-like conversation yet. Emotional element is mentioned as one of the causes. To prevent this problem, discovery and analysis of emotion contained in the document is a very important issue. There is Plutchik emotion model that as one method to analyze the feelings. That sees emotions as consists of a combination of eight primary emotions. In this study, we try to introduce Plutchik emotion model into the conversation system. For emotion analysis of text using an emotion model, the emotion value must be given to the words that are the smallest unit of text. But, it put a lot of labor to obtain it with set out a questionnaire. In this study, we constructed the lexical network from a sentence of interpretation of a word, for the purpose of determining the emotion values about a lot more words from the basis words. As a result, we obtained lexical network with the nodes of about 500,000 that consist of two links of the same orientation link and the reverse orientation link.

In the consciousness studies of recent years, scientific and logical approaches on clarifying consciousness have become the object of analysis and the problems resulting from it have been systematically studied. One of the major problems scientists have faced is: How is it possible to ensure the objectivity that transcends the paradox that the object a researcher studies encompasses the researcher himself/herself? In this paper, I will clarify the difference between the viewpoint brought about by the conventional human thought patterns and the completely new viewpoint that is based on the system: Simultaneous Existence with Dual Structure. In addition, I will introduce some examples in which the structure observed by the new viewpoint not only induces the unification of a person's ego and the world the person sees (the extinction of ego through the unification of subject and object), but also transforms the world the person sees. Furthermore, I will present an assumption that the unification of a person's ego and the world the person sees represents the emergence of consciousness and that the observation as a result of understanding the structure of the emerging consciousness brings about the quantization of consciousness in the macro domain. Lastly, we will mention the possibility of social reproduction brought about by the quantization of consciousness.

To do the human body damage evaluation when the wheelchair failed, HIC and AIS at the fall were examined. When HIC installed it with 2120 and AIS6, the side fall of the wheelchair was HIC340, and AIS2 in the helmet non-installation for the bicycle. A rear fall of the wheelchair was unrelated to the presence of the bicycle helmet and 9 or less was AISO in HIC. Because the cause collides with ground on the tip of the handgrip part of the wheelchair the head and is decoupled. When the helmet for the bicycle was installed when there was personally an impact on the head like the side fall, it was understood that impacts decreased up to about 1/4 compared with non-installing it. As a result of this experiment, it has been understood to have to install the protector that absorbs the impact such as the bicycle helmets in the wheelchair boarding.

Micro movement of the center in the brain and deformation of the skull due to hitting is calculated precisely without approximation from the acceleration data of 7 experiments of backwards falling down. The experiment has been done in JARI, and acceleration data are taken on the head, chest, pelvis and also neck (force) using a dummy robot, which simulates a human body. As a result, the whole picture of the falling and hitting becomes clear. It is shown that (1) the postures of falling are classified into 2 types, i.e., nearly same time hitting or delayed hitting of the pelvis. (2) Accelerations of the head are classified into 2parts, i.e., head's decelerating period and hitting on the floor. (3) The depth are from 2〜3 mm, which indicates the deformation of the skull is around 2mm. On the other hand, the height range from I cm to 7cm, depend on the falling posture. (4) The inclined angle of the face has been calculated.
