Brain Machine Interface(BMI)is an interface for machine control using the activity information of the brain. It enables users to operate the machine with only their thought,so it indicates possibility of supporting life of people who has Amyotrophic Lateral Sclerosis(ALS).In case of applying BMI to the machine that substitutes the body movement like an artificial arm,it is desirable to control the machine by motor imagery matched the movement.However,there is little information about discrimination of some kind of motions with a part of body as hand or foot.The purpose of this study is to develop BMI for supporting hand motion.In this paper,we tried to discriminate the difference between an opening action and a grasping action with the right hand of the subjects by using Electroencephalogram(EEG)signal which occurs at the time of their motion imagery.As the result of analysis,it was confirmed that the average discrimination accuracy is 68.7%.

In recent years, formation control has attracted considerable interest among control engineers. As one of the formation control methods, we deal with the leader-following formation navigation (LFFN). The LFFN is defined that a human operator or an autonomous leader robot forms a queue of robots to guide multiple followers. The followers pass along the leader's trajectory with the same motion as the leader. When the leader passes along a safe route to avoid obstacles, the followers also pass along similar safe trajectory. However, using by the LFFN in real environment, it is necessary to consider a movement in three-dimensional space such as multi-storey car park and grade separation.In this paper, we proposed a method to extend the movement in three-dimensional space and the movement is demonstrated by a simulation with the proposal method. As a result, the simulation of three-dimensional extension by LFFN was confirmed.

The purpose of this study was to examine how various kinds of refreshments have effects on a concentration of brain activities determined by the NIRS. After the subjects performed mental-arithmetic for 10 minutes, they took a rest at a specified method and repeated mental-arithmetic for 5 minutes. We designated the three rest methods as follows:1. taking a deep breath,2. listening to a subject's favorite song, 3. listening to a classical music determined by examiners. In cases of taking deep breathing and listening to a classical music, there was the relaxation and subjects kept the concentration. Although the relaxation effect of the listening to a favorite song was the largest, the intensity of concentration was different by a subject, that is, the effect should be different by the music chosen by the subjects.

Several types of systems for disaster communications and networks have been studied to comprehend damage situations immediately in a heavy disaster. We have, however, been confronted with difficult issues to deploy the system actually in society, and it has not been raveled yet. To promote deployment of such a disaster resilience system, we have carried out an experimental study in the project-based learning program (PBL) of National Institute of Technology, Hakodate College (HNCT). Examining wireless mesh-networks called NerveNet, which was developed by the National Institute of Information and Communications Technology (NICT), we set up the wireless networks experimentally in HNCT. Reviewing the requirements of local governments on disaster damage assessment, we propose an impetus model to deploy the disaster system in society by exploiting a regular educational program, PBL. This paper shows a testbed of wireless mesh-networks, which is configured with NerveNet and implementing required functions in web application forms.

Recently, to reduce the inconvenience caused by authentication operations in portable terminals such as smartphones, various authentication methods based on behavior characteristics have been studied. We proposed authentication method which identified individuals based on walking motions measured by wearable sensors such as acceleration sensors, and can be implemented on a smartphone (as smartphones are equipped with sensors). In the many case of multimodal biometrics authentication with machine learning, the common classifier for all users is generated. One of the reasons for this is that these authentication systems are installed into the equipment shared by users, such as the server computer. This server computer identifies the all authorized persons and the non-authorized persons. However, each smartphone is occupied by each user and is not shared by the multiple users. Therefore, the classifier to each user for fusing the features can be generated for each user in their smartphones. The purpose of this paper is to reveal the influence by generating the individual classifier for each user and a common classifier for all users. We evaluated the authentication accuracy by employing both the classifiers generation methods.

The purpose of this study was to remove phosphate from the rivers flowing into Onuma Lake by the water clarifier sludge. The water clarifier sludge showed the capacity to absorb phosphate of 362mg/m³ by a soil-filled column testing. Adsorption ability of phosphate was also confirmed in a field testing using biotope. However, the adsorption ability of phosphate could not be estimated due to mixing of a soil at the bottom of biotope into the water clarifier sludge.

Antifungal activity of Fukurofunori (Gloiopeltis furcata) was examined using one of potato scab pathogens, Streptomyces scabiei. Fukurofunori was extracted with acetone at room temperature for a week, and its solution was tested as antifungal samples. As a result, the minimum inhibitory concentration (MIC) value of the extractives showed about 160 ppm against Streptomyces scabiei. By gas chromatography / mass spectroscopy (GC/MS), it was suggested that antifungal components were fatty acids, such as 14:0, 16:0, 18:0 and 18:1.

Antioxidant activity of extracts from Sugi (Cryptomeria japonica) bark was examined by using 2,2-Diphenyl-1-picrylhydrazyl (DPPH) radical-scavenging method. As a result, 70% acetone extract of Sugi bark was 1629 μmol/g ± 107. And they were fractionated into three layers, i.e., hexane, ethyl acetate (EtOAc) and pure water. Among them, the EtOAc-soluble fraction showed 2950 μmol/g ± 210, which showed an activity equivalent to that of rosemary extract. In addition, these solutions were separated aqueous layer and the EtOAc layer using column chromatography. As a result, 50% acetone elution department of the aqueous layer showed 5122 μmol/g ± 141, 70% acetone elution department of the EtOAc layer showed 6879 μmol/g ± 120, which was found to increase about 3〜4 than that before the fractionation.

As the homeroom teacher, the author¹ conducted a three-day-interview with a first-year student named "A," who failed "General English I." The interview was held in the spring break in March 2015 after the completion of the first year (April 2014-February 2015), as the break between fiscal school years allowed the teacher and student to optimally utilize the time for the supplement. Through the interview, A's learning mind about English was reflected upon to analyze his English proficiency and his English learning mind, and to design tangible action plans to support him in the following year's English class, which was to be taught by the author. During the interview, A's habit of holding a pencil causing postural stress was observed. Through his oral reading performance, his English pronunciation was evaluated as above average. Through the interview, three aspects were reflected upon; (1) A's English studying history, (2) A's learning attitude toward English in our school, and (3) A's learning mind. From an analysis of the reflections and observations about A, it was observed that the reason why only A had failed "General English I" was not his lack of proficiency in English but his fixed mindsets for English study.

Full mold casting method, using a model such as foamed polyethylene, is a casting technique to manufacture a cast product having the same shape as the model shape. This casting method is a kind of evaporative model casting process, and is widely used. In Hakodate College, it has been adopted to manufacture aluminum nameplates during student practice. In this casting process, in order to obtain a stable cast product, it is necessary to supply a constant melted metal flow, into the foam model that was embedded into dry sand. This paper shows two methods for the constant inflow of melted aluminum amount in the full-mold process, which are setting a pouring guide and increasing burying distance of a foamed plastic model. Also, this paper reports the practice results of applying these methods to the student casting practice.
