概要: In this paper, a low-cost and safe non-thermal food processing technology is presented for shockwave nonthermal food pro cessing. Unlike the conventional system, the proposed system employs multiple large output capacitors with low withstand voltage characteristics to generate underwater shockwaves, where the multiple output capacitors are charged at low voltage. For this reason, safe and low-cost non-thermal food processing is achieved by the proposed system. To confirm the feasibility of the proposed technique, some experiments are conducted on the experimental prototype of the proposed system. The experimental results demonstrate that the proposed system with a 3300 μF capacitor can process apples at the output voltage 865 V. 続きを見る

概要: The Silicon Nitride (Si₃N₄) has drawn much attention as electrical substate materials for power module. One of the facto rs that decrease the thermal conductivity of Si3N4 is phonon scattering caused by the lattice oxygen. Yttrium disilicide (YSi₂) is expected to act as an effective oxygen getter that would actively remove impurity oxygen contained in the raw materials and further added during processing. It was found that the addition of YSi₂ significantly inhibited the phase transformation and densification, which would suggest that YSi₂ effectively acted as an oxygen getter to decrease the SiO₂ content, and hence the amount of the liquid phase. Although the thermal conductivities of gas-pressure sintered Si₃N₄ were improved with increasing the amount of YSi₂, those of reaction-bonded Si₃N₄ were significantly deteriorated due to their much smaller grain size. 続きを見る

概要: The techniques to assemble cells into desired integrated shapes, that is known as 'tissue engineering', is important for regenerative therapies. Especially, anisotropic structure formation is key for many applications. Here, anisotropic nanocomposite hydrogel film that consist of liquid crystalline fluorohectorite nanosheets and poly(N-isopropylacrylamide) (pNIPAm) was investigated as the cell culture medium. Melanoma cells cultured on a glass plate or a polystyrene plate possessed spherical shape with the size of around 10 ȝm, which is generally found for melanoma cells. In contrast, the melanoma cells cultured on the pNIPAm and FHT/pNIPAm composite hydrogels possessed elongated shapes with the length of more than 50 ȝm, indicating strong adhesion to the gel. Based on the present results, future development of a facile tissue engineering technique for anisotropic cell assembly is expected. 続きを見る

概要: Using an injector with a lift sensor, the needle valve openings during injection were measured. Injection with different maximum needle valve openings was achieved by varying the injection signal to injector. A laser 2-focus velocimeter (L2F) was used for measurements of velocity and size of droplets inside diesel sprays intermittently injected into the atmosphere by using 8-hole injector nozzle. The diameter of the nozzle orifice was 0.125mm. The rail pressure was set at 40 MPa. Measurement plane was located at 7 mm downstream from the nozzle exit. The spray image was taken by the high-speed camera, and the spray width was evaluated by using spray image. The spray width at low maximum needle valve opening was wider than those at high maximum needle valve opening. Droplet velocity is lower and droplet size is smaller at low than at high maximum needle valve opening. Radial distances of measurement position were nondimensionalized by maximum spray width. The effect of the maximum needle valve opening on droplet velocity and size were small at the spray periphery. 続きを見る

概要: Generally, flexible steel plates are transported by rollers. However, the contact between the roller and steel plate degrades the surface quality. One of the solutions to the problems is the non-contact transport system by magnetic levitation using electromagnetic force. However, flexible steel plate is easy to fall by deflection. Therefore, in this paper, magnetic levitation system by changing direction of flexible steel plate was proposed for decreasing the deflection of steel plate. Moreover, characteristics of attractive force for flexible steel plate was investigated by magnetic field analysis. The results suggested that flexible steel plate is levitated by realizable coil current condition. 続きを見る

概要: In this study, we implemented a ultra-realistic Japanese traditional craft system using mixed reality technology. By using this system, the user can place any traditional craft object on the MR space. When placing a traditional craft object in MR space, the user marks spherical pointers by using the HandRay function. This calculates the center coordinates, distance, and placement angle between the two markers. Furthermore, the traditional craft object is placed in the MR space by calculating the coordinates and distance from the floor to the upper part of the door frame. In the future, in order to realize communication between users and traditional craft dealers, we aim to realize a MR space sharing function by multi-users. 続きを見る

概要: This paper studies robotic insertion planning for board-like objects as an assembly primitive motion. Assembly of industrial parts in mass production is a bottleneck for factory automation because such a complicated and combined task requires robots to handle various parts, including deformable objects. In addition, synthesizing these primitive motions for assembly and other supplemental equipment is essential, for example, parts feeding and work transfer. This paper briefly summarizes the trend of robotic assembly research and competitions. It also introduces our perception and planning method for the insertion task by a robotic manipulator and a depth camera. 続きを見る

概要: The diameters of sheep gut handled should be measured using image processing at factories. However the appearance of the sheep gut to be measured changes depending on the water flowing inside the intestine. Therefore, we checked the tendency of the visual diameter to change due to flowing water and found that the smaller the actual diameter of the sheep intestine, the greater the shrinkage of the visual diameter. Comparing the estimated diameter with the actual measurement, the RMSE was 0.95 mm, achieving the accuracy goal of 1 mm. Therefore, we concluded that it was effective for practical use. 続きを見る

概要: The first session of the 117th Congress (2021-2022) was a year of significant change for supply chain security in two ways. The supply chain security community made progress on the revision of NIST SP 800-161, the basic document in the area of supply chain security, and on the rapid development of key policies in response to major security incidents, such as the Colonial Pipeline incident and the Log4j vulnerability incident. On the other hand, there have been the following room to do. The Cybersecurity Maturity Model Certification (CMMC), a framework for mandatory information security measures for contractors in the Department of Defense, was temporarily suspended. And a bill that would establish a new information sharing framework between the public and private sectors regarding security incidents did not reach an agreement. Those may indicate the difficulty of making information security management mandatory, which was originally based on the voluntary approach. 続きを見る

概要: Orono-shima Island is a remote Island in the Tsushima Strait, it is 4.3km around. Since ancient times, it has been a landmark when crossing from the Korean Peninsula to Japanese archipelago via Tsushima Island and Iki Island. However, large-scale ruins and burial mounds are not known on Orono-shima Island until now. The author has conducted various surveys of Koro Island and found the possibility that this island was an important island in ancient times. As a result of ground survey, the author discovered a topography like keyhole tomb which is a characteristic Japanese burial mound, on the northern cape of the island. It could be up to 150m in size, one of the largest around Kyusyu Island. There is no burial mound comparable to this on a remote island in Japan. Therefore, we created a 3D image using a drone Laser and hand Laser surveying of this terrain and we compared the results with another keyhole tomb. We asked archaeologists to judge the results. He stated that this could be considered an artificial structure and that excavation would eventually be necessary. Therefore, we investigated in detail the sites that could be candidates for excavation. In addition, we analyzed the image of infrared radiation of Orono-shima Island took by Landsat8. In conclusion, it was speculated that this topography was the prototype of the oldest type of keyhole cairn tomb in Japan. The topography of the northern part of Orono-shima could be regaining the missing link between the cairn on the Korean Peninsula of the first century and the oldest type of keyhole cairn tomb in Japan of the third century. 続きを見る

概要: This paper investigates why local councils do not improve the women’s working environment. One of the reasons is that th ere is a low percentage of women local councilors. In order to evaluate the working environment, we introduced an indicator which reflects (1) the availability of childcare facilities, (2) the availability of breastfeeding rooms, and (3) the implementation of sexual harassment training. The indicator revealed that the percentage of women councilors in the municipalities with populations of more than 500,000 and populations from 100,000 to 300,000 positively affected their working environment. The low percentage of women in councils is hindering the improvement of the working environment and is also related to the lack of improvement of the women’s working environment in society. 続きを見る

概要: The functional category T in a clause undergoes feature inheritance of ϕ-features from C in the system of complementizer .This feature inheritance bears by-products, and one of them is complementizer agreement observed in many languages,especially in West Germanic languages. The ϕ-features in T that are inherited from C percolate up from T to C, which is caused by requirements of the principle called “Percolation” applicable in istributed Morphology, a grammatical level between Narrow Syntax and PF Interface. Some cross-linguistic variations of this complementizer agreement depend on the interaction among the principle Percolation and the hierarchy of the ϕ-features. Features other than ϕ-features, i.e. tense feature and mood feature, also undergo feature inheritance from C to T, and feature percolation of the features in T inherited from C occurs due to requirements of the principle Percolation. 続きを見る

概要: Collagen is one of the proteins that compose the bones and skin of mammls and fish, and is sensitive to heating. Heatden atured collagen, called gelatin, is also widely used as a raw material for pharmaceuticals, cosmetics, and foods. In this study, a new extraction method was developed to increase the efficiency of gelatin extraction from hard fish scales. When the fish scales were crushed for 2min and then pocessed under vacuum at 40℃ and-30 kPa in dilute hydrochloric acid, gelatin could be extacted in 64.8% yield. This results suggest an innovative method to extract gelatin from hard tissues such as fish scales with convenient and less acid. 続きを見る

概要: Inorganic nanosheet/polyurethane nanocomposite elastomers were synthesized in the form of thin films. To synthesize the composite film, layered clay mineral fluorohectorite was first exfoliated into single-layer nanosheets in N,N-dimethylformamide/water mixture added with the prepolymer, isocyanate-terminated low-molecular-weight poly(ethylene oxide). The mixture was then contacted with the solution of four-functional crosslinker molecule, triethylenetetramine, resulting in the formation of urethane bonds that crosslink the prepolymers. The obtained composite elastomer films showed largely improved mechanical property compared to the elastomer without the nanosheets. The composite elastomer film will be applicable in many fields such as dielectric elastomer generator. 続きを見る

概要: The boronic acids are significant functional groups for design of chemical sensors for sugar recognition, because they are known to form ester with diols. In this study, we report a research on responses to uncharged sweet substances using a lipid polymer membrane consisting of tetradodecylammonium bromide (TDAB) as a lipid, dioctyl phenylphosphonate (DOPP) as a plasticizer and 3-nitrophenylboronic acid (3-NPBA) as a sugar recognition site. This sensor showed positive changes in membrane potentials to uncharged sugars such as monosaccharides and sugar alcohols, while no response to disaccharides such as sucrose or sucralose. Moreover, the sensor response has a positive correlation with the concentration of boric acid (0-5%). The results revealed that the phenylboronic acid derivative could be a useful functional substance in a lipid polymer membrane of a potentiometric sweetness sensor for detecting electrically neutral sugars. 続きを見る

概要: Typhoon №19(Asian name is Hagibis), which hit Japan in 2019, left large scars in various parts of Japan. Japanese people had been plagued by flood disaster since ancient times, it has recorded the height of floods and tsunamis in various ways on land. Since the early 17th century, it is often indicated by stone or stake monuments of flood water level marks, but in ancient times, there was a possibility to inform the height of flood level by building a shrine. Research has also begun to match the location of old shrines and temples with data on floods and tsunamis.In general, it is thought that more than 1,100 years have passed since the founding of the old shrines called "Shikinaisya", and it is likely to be used for such data. However, Morita shrine which is "Shikinaisya" was greatly damaged by 2019 flood. We considered what kind of shrine was suitable for data use from the example of Morita Shrine or others. In addition, we considered the appropriateness of flood hazard maps from the records of ancient shrines which was swept away. As a result, it was found that some of the candidates for the ancient shrine indicated the level of flooding, some shrines were washed away many times and they were considered to have been rebuilt or changed their place. And the expected flood area of the current hazard map was almost agreed with the records of the ancient shrine where the buildings were washed away. 続きを見る

概要: Recently, it has become clear that there are two clades in Liobagrus reinii, which can reasonably be judged as separate species. In this study, we attempted to clarify the differences in distribution and habitat of the two clades of Liobagrus reinii in the Gonokawa and the Ota River Systems by using environmental DNA analysis metabarcoding. In the Gonokawa River System, the number of the present sites and environmental DNA concentrations of clade 1 were higher than those of clade 2. In the Ota River System, the number of the present sites and environmental DNA concentrations of clade 2 were higher than those of clade 1. In both river systems, clade 1 tended to be found at lower elevations and clade 2 at higher elevations. 続きを見る

概要: The cartography analysis in syntax has dealt with wide range of syntactic phenomena. The functional categories in the le ft peripheral area of the cartography have their own discourse function. Based on the cartography analysis, this paper shows the possibility of occurrence of a projection called “MoodP” above FinP in the left periphery of clauses. MoodP bears the function of expressing speaker’s mood or modality concerning uncertainty, presupposition, command, advice, exclamation, remorse,disappointment, agreement, tense, negation, etc. These features concerning mood or modality in MoodP undergo feature inheritance from MoodP to T. Complementizer agreement is one of the by-products of the feature inheritance. The ϕ- features in T that are inherited from MoodP percolate up from T to Fin, which is caused by requirement of the Optimality Theoretic constraint called “Percolation” in Distributed Morphology. 続きを見る

概要: The supercritical carbon dioxide (scCO2) for the impregnation and deposition of metal nanoparticles are effective for uniformly decorating and impregnating porous materials. In this work, Cu-Ru bimetallic nanoparticles were successfully immobilized in the mesopores of hierarchical porous SiO2 by using scCO2-acetone solution. STEM-EDX mapping measurements demonstrated that Cu and Ru atoms were homogeneously scattered in mesopores of hierarchical porous SiO2. The resulting Cu-Ru@SiO2 exhibited high activity. The catalytic activity of bimetallic Cu-Ru@SiO2 for CO oxidation was higher than that of monometallic Cu@SiO2, Ru@SiO2 and Rh@SiO2. 続きを見る

概要: A laser 2-focus velocimeter (L2F) was used for measurements of velocity and size of droplets inside diesel sprays intermittently injected into the atmosphere by using 8-hole injector nozzle. The diameter of the nozzle orifice was 0.125mm. The rail pressure was set at 60 MPa, and the injection quantity was set at 4mm3/injection. Measurement plane was located at 10 mm downstream from the nozzle exit. The spray image was taken by the high-speed camera, and the spray width was evaluated by using spray image. The spray width was large at the early period of injection duration. The size of droplets was small at the time when the spray width was large. It became clear that there was a negative correlation between the spray width and the size of droplets. 続きを見る

The Kraepelin-task is a calculation task of addition of a one-digit number to another for a definite period of time and subjects are asked to answer it as many and correctly as possible. The result implies that longer viewing distance would decrease wrong answers and improve accuracy of calculation, and it also implies that longer viewing distance would alleviate an amount of increase of physiological fatigue added during the calculation and make physical fatigue less severe except on eyes. 続きを見る

概要: We proposed the new digital filter algorithm for reduced noise of electrocardiogram (ECG) derived from the head. The proposed algorithm is based on the estimation technique of noise from one beat of ECG during exercise. The estimated noise is updated by 50% of noise derived from the latest beat and 50% of the noise derived from accumulated beat. The updated noise is devoted to ECG for detection of R-peak in next beat. In 3 healthy male participants, stationary state and 40, 50 W loads exercise using cycle ergometer for 30 seconds was performed, respectively. The results indicate that noise of ECG derived from head is decreased. In conclusion, these findings suggested that the proposed adaptive filter might be practical signal processing for reduced noise of ECG derived from head. 続きを見る

概要: There are many river crossing structures not only in developed countries but also developing countries because of irrigated agriculture. On the other hand, the number of fishways for river ecosystem conservation is not good enough in many countries, and tentative fishways, such as siphon system pipe-type fishways, will play an important role in these countries. When tentative fishways are installed in rivers, of course, fishway technologies are important for their good works, however, regional inhabitant conditions around the weirs are also the critical situation in order to operate these fishways effectively. This paper focuses and views regional inhabitant conditions for tentative fishways with their cases at two rivers in Indonesia. 続きを見る

概要: Orono-Island is a remote island in the Sea of Genkai. The author conducted an environmental survey of Orono- Island.The research was ecology investigations for wild birds and endangered plant species. The studies developed from these research lead to some unknown history of Orono-Island. It was relationship between Kuroda domain and Orono-Island. The second conclusion is that Onogoro-Island was Orono-Island. Onogoro-Island was the first land created by the creation gods which first appeared in Japanese mythology. Because the birou(Livistona chinensis) used by the ancient emperor for the ritual were on Orono-Island. It was thought to be related to solar rituals and the distribution of native birou (Livistona chinensis) around Kyushu-Island. In addition, The place name and shrine of Kyushu Island which comes out in the myth were also related to Orono-Island. Further, conclusions of first one and second one must were correlated. Kuroda Narikiyo visited Orono-Island because he thought that Orono-Island was Onogoro-Island of the Japanese myth, and so he wanted brought back a characteristic plant. 続きを見る

概要: This paper deals with the extra-vocalizations and episodes as political rhetoric in Japanese political interviews and wi ll show how they used them. The quotation of extra-vocalizations and episodes is assumed to be a characteristic of politicians’ unique way of speaking and is used to obtain the attention of the audience and increase their persuasiveness. Four interviews were used to analyze the use of rhetoric in 110 responses, with 33 (30.0%) quoting extra-vocalizations and 16 (14.5%) talking about the episode. The analysis revealed that regard to the quoting extra-vocalizations, the ruling party members use it as a reinforcement of their statements, while opposition members use it as a contrast of the hostile statements. Analysis results showed that when talking about an episode, there are those that simply talk about their own experiences and contribute to a smooth interview and those that quote and critique others’ statements at the same time as the episode. By revealing the way political rhetoric is used, viewers will be able to carefully listen to the politicians’ story without being misled by political rhetoric. 続きを見る

概要: We introduced a liquid helium-free cryostat for studying quantum mechanical electron transports in semiconductors or topological insulators. This cryostat can cool the samples down to 1.5 K and is equipped with 14 T superconducting magnet. The resistance standard originating from the conductance quantization was accurately measured by the quantum Hall effect measurement in a Si-modulation-doped AlGaAs/GaAs single heterostructure, in which high-mobility two-dimensional electron channel was formed. In addition, diamagnetic levitation of bismuth was successively observed. Further enhancement of our study is expected using this cryostat system. 続きを見る

概要: In this study, supercapacitor electrodes were synthesized from crab shells, which account for about 30,000 tons of the seafood caught every year in Japan. Although many studies have reported using an electric furnace, in this research, the crab shell materials were carbonized and activated in a microwave oven. The aim of this research was to investigate the performance of a supercapacitor when the crab shell materials are carbonized and activated with microwaves. Electrodes were prepared from the obtained activated carbon, and these capacitances were measured by the cyclic voltammetry method and the internal resistances were measured by the alternating current impedance method. The results of this study indicate that capacitance increased in proportion to time and wattage of microwave oven. 続きを見る

概要: The high-pressure fuel generator was developed for the generation of high-pressure fuel spray. When the target pressures of common rail at the high-pressure fuel generator were set at 60, 80, 100 and 120 MPa, and the mean pressures of actual pressure of common rail were 60.04, 80.04, 100.10 and 119.85MPa respectively. Moreover, the measurement system, that is, a laser 2-focus velocimeter (L2F) was developed for the evaluation of breakup of droplet inside the diesel fuel spray. The L2F has a micro-scale measuring volume which consisted of two foci. The focal diameter was about 3 μm, and the distance between two foci was 20 μm. The velocity and size of droplets inside the spray can be measured by using L2F. The maximum data sampling rate of the L2F system was markedly high as 15 MHz. 続きを見る

For the accurate measurement of void fraction using this method, it is essential to identify the cause of havingthe a negative value of void fraction. The experimental result of a single bubble through the nozzle showed that the void fraction becomes negative when the bubble contacts with one electrode and do not contact with the other electrode, whilst the void fraction correctly becomes positive when it contacts with the both electrodes or do not contact with the both. 続きを見る

Infrared spectra confirmed the successful modification of MCM-41 with the ssDNA via 4 synthetic steps. To close the pore gate, the surface ssDNA was hybridized with linker ssDNA having complementary base sequence on both ends. The pore gate was then opened again by hybridization with the ssDNA having complementary base sequence only on one end and BHQ-1(fluorescence quencher) on the other end. The gate opening process was confirmed by observing the fluorescence quenching of the FAM on the surface-modified ssDNA caused by the BHQ-1. 続きを見る

概要: Congenital heart disease such as Ventricular septal defect (VSD), Hypoplastic left heart syndrome (HLHS) and Single Ventricle (SV) have malformations and dysfunctions in the cardiovascular system. In particular, HLHS and SV have a high risk of death due to severe symptoms such as breathing disorder, hyperhidrosis, suckling disorder and cyanosis after birth. Therefore, surgical treatment is immediately considered. To reduce pulmonary vascular resistance, BT shunt or bilateral pulmonary artery banding is performed after birth. In this procedure, a tape of a vascular graft made of ePTFE is wrapped around a blood vessel to control blood flow toward the lungs. In this study, the ultra-small crip with automatic adjustment of banding diameter by wireless communication for blood vessel banding is considered. In this paper, a numerical analysis model of blood vessel and a tape of a vascular graft for blood vessel banding using Finite Element Method is investigated. 続きを見る

概要: Recently we developed a novel optical detection system that allowed real-time in-situ simultaneous monitoring of dissolved oxygen and materials movements at a vicinity of micrometers from an aquatic plant by combining deflection of a probe beam and fluorescence quenching. In the detection system, dissolved oxygen (DO)-quenched fluorescence was monitored, and then DO concentration was calculated from the DO-quenched fluorescence intensity by an algorithm based on fitting calculations of quadric equations in software of Origin. Here, an improved algorithm based on fitting calculations of cubic equations in the most widely used Microsoft Excel was proposed. The algorithm contained Excel macros of adjusting monitoring time between DO and temperature sensor software and digital multimeter controlling software, deleting large noise of fluorescence intensity monitoring, and fitting calculation of cubic equations. Also, fixing aquatic plants was improved. Results showed that the algorithm in the Microsoft Excel gave good results for monitoring of DO at vicinities of aquatic plants. 続きを見る

概要: Coaxial probe reflectometry is a powerful method to evaluate complex permittivity of materials in broadband microwave fr equency range. This method requires reference materials, and then water is typically used because of its easy availability and high dielectric constant. However, water is no longer used below 0 °C since it freezes. In this paper, some of optical crystals, KRS-5 and sapphire, are proposed as alternative reference materials to water. These materials have high and frequency independent dielectric constant in microwave frequency range. A fixture to install a disc-shaped crystal to the probe was also developed. The performance of using these optical crystals as references was evaluated by measuring ethanol and compared to conventional method. The result reveals KRS-5 and sapphire can be actually used as reference materials with comparable accuracy to water. 続きを見る

概要: Interactive Evolutionary Computation (IEC) is well known approach searching good solutions for each user in terms of finding good graphics, sounds, and music pieces. This study aims to propose IEC with multiple users for creating fragrance. The fragrances are composed of several aroma sources; therefore, target of the proposed method is to optimize intensity of each source aroma. While the general IEC searches good solutions for each of the users, the proposed method can search good or optimal solution between the users by changing good solutions between the users during the search. In this study, a concrete system was constructed to show a fundamental efficiency of the proposed method. 続きを見る

概要: This IoT faucet including sensor nodes has been developed to monitor the usage of the indoor faucets. The usage logs of the IoT faucets in kitchens and bathrooms can be used to determine if residents are safe. As the IoT faucet is an indirect activity monitoring system, the advantage is that the effort of both the watcher and the watched person is reduced. This paper is a preliminary discussion of our efforts through trial and error to install the IoT faucets as part of an activity monitoring system. As an experimental result, the usage of the IoT faucet was detected and the activity could be estimated under the condition that the difference between the room temperature and the water temperature of the IoT faucet was more than 0.6 degrees Celsius. 続きを見る

概要: Various natural disasters such as earthquakes, typhoons, and heavy rains occur every year in Japan. When a natural disaster occurs, each local government establishes disaster response headquarters and makes efforts for disaster response. However, since a large amount of information is gathered at the disaster response headquarters, it is difficult to quickly organize and share these pieces of information. Therefore, we developed a public assistance system to support quick disaster response by utilizing past disaster response records. The public assistance system supports a quick grasp of past disaster response information by using a full text retrieving engine. 続きを見る

概要: Our research group has established a technique to make three-dimensional cell constructs using only cells. The cell constructs are made using spheroids consisting of only cells. The quality of the spheroids is important as it is necessary to provide reproducible spheroids. Therefore, it is necessary to morphologically evaluate spheroids non-invasively. The quality of spheroids was evaluated regarding area, diameter, and circularity. However, the concentration distribution of the spheroids had not previously been visualized. This study aimed to visualize the cell distribution inside spheroids using pseudo-color display processing. By applying pseudo-color processing to the grayscale spheroid images, we succeeded in visually grasping cell distribution and shape. In the future, we will actually observe inside the spheroid and aim to further improve the accuracy by correlating with the specific conditions. 続きを見る

概要: Along with the development of non-invasive techniques for the high accuracy measurement of blood pressure on the finger, the investigation of finger pulse volume (PV) variability has been attracted considerable interest. Modified normalized pulse volume (mNPV) has the potential to be a practical index for the determination method of mean arterial pressure (MAP) based on the volume clamp method due to its very sensitive to vasoconstrictor stimuli on the finger. However, MAP derived by mNPV has not yet been investigated. Therefore, we compared MAP measured by sphygmomanometer as a reference, with MAP derived by the PV and mNPV using the developed prototype system during baseline in ten young subjects. The results gave mean differences in Bland-Altman plots between the measured MAP and MAP derived by PV and mNPV of 1.86 ± 6.49 (standard deviation) and -2.54 ± 8.12, respectively. mNPV is discussed in terms of the availability for determination of MAP based on VCM. In conclusion, mNPV is a valid approach, which might be useful for the calibration index of MAP derived by PV. 続きを見る

概要: The freehand 3D ultrasound is useful technique to acquire 3D ultrasound volume using a conventional 2D ultrasound transducer. The technique constructs 3D volume using 2D image and positional information. Meanwhile, it has two technical issues to widely apply in clinical setting. Firstly, position sensor is expensive and needs to prepare for use. Another is high computational cost in volume construction. To address the issue, orientation measurement by a low-cost inertial measurement sensor and highspeed volume construction using parallel computing technology by a graphics processing unit were proposed. In this study, the potential of this approach is investigated and 3D volume reconstruction was demonstrated. 続きを見る

概要: In this research, in order to realize the IoT -DRR, we first verify the debris flow reaches the river way and flows down, in the case of a river blocked by earth and sand once, after the water accumulates and collapses at a stretch and a bore occurs or when a steep wave rises due to a sudden rise in water level due to the release of the dam. The time step of observation for the conventional water level sensor is not suitable, because it cannot capture the rapid bore phenomena, we propose a system to replace the conventional water level sensor and prediction system. After that, we also propose a system to inform the warning with network of the river bed and height of terminals and sensors. These advantage is already certified for patent in Japan. 続きを見る

概要: Second space exposure experiment “TANPOPO 2” on the International Space Station was planned for study of origin of life. Authors were tried to synthesis peptides those are condensation products of amino acids, because peptides syntheses are the most important step for the producing proteins on the primitive Earth before the first life aperance. Although, in our preliminary experiments in the first space exposure experiment “TANPOPO”, authors found dialanine that is a dipeptide from amino acid, alanine, the experimental result was not enough to conclude peptide formed in the space. Therefore, precise experiments were planned in the “TANPOPO2”. Stable isotope labeled alanine was used for preventing the biological contamination, three different patterns of amino acids were chosen to conclude wide variety peptides formation. In this experiment, thin film formation apparatus using vaporization of amino acids, spectrometry of vacuum ultraviolet adsorption were prepared for the space experiment. And the space exposure experiment was started from August, 2019. 続きを見る

概要: The purpose of this study is to discern the relationship between spatial accuracy, timing accuracy, and bat control and hitting accuracy for elite collegiate baseball batters. Nine college baseball batters performed three tasks. The first task was hitting a fastball thrown by a pitching machine (HPT). The second task was observing a pitching machine’s fastball and indicating the location (OPT). The third task was hitting a ball on a baseball tee (TBT). The subjects’ performance in hitting accuracy was defined by their success rate in the HPT. The distribution of the point of ball-bat impact in the TBT represented the subjects’ ability in the bat control. The fluctuations in the location in pitcher-to-catcher direction between the HPT and the TBT represented the subjects’ temporal accuracy. The subjects’ spatial accuracy was defined by their performance in the OPT. Although they were able to control their bat swings to hit a ball within the effective impact area most of the time in the Tee Ball Task, timing and spatial components of their performance indicated larger errors and lower precision. Our results suggest that the perceptual skills involved in baseball hitting are the main reason why batters fail to hit a ball accurately. 続きを見る

概要: The functional categories in the left peripheral area of the cartography have their own discourse function. Force in the left peripheral field activates as a force marker. However, this paper shows that Fin in the left peripheral field can operate as a force marker and a verb moves up to there due to inheritance of [+attract] feature from Force to Fin. The framework presented here provides a straightforward account of V1, V2 phenomena in Germanic languages. English shows cyclic demise of V-to-C and V-to-T movement in its history. A set of puzzles concerning the patterns of the phenomena is explained as a consequence of the analysis which admits gradual demise of verb attraction to Fin. Furthermore, this paper addresses the possibility of occurrence of MoodP between ForceP and FinP in the right periphery of clauses as well as in the left periphery of them. MoodP bears the function of speaker’s mood of utterance and interacts with Force in attracting verbs to Fin. The demise of Kakari-musubi in Japanese is closely related to the loss of verb movement to Fin. 続きを見る

概要: This paper addresses cross-linguistic variation and diachronic change of complementizer-trace chain in the embedded clauses, deriving the distributional properties from interaction among empirically well-motivated constraints in Optimality Theory (OT) that we propose and their hierarchy. The constraints concern restriction on head, economy of representation, and semantic interpretation. In line with OT, the constraints are stratified according to the descriptions of grammatical structures. The interactions of the pivotal constraints determine the occurrence of (null-) complementizers. Furthermore, the constraint interactions and their different hierarchy can provide a unified account for the cross-linguistic variation concerning the occurrence of complementizer-trace chain and its diachronic change in the history of English. 続きを見る

概要: The cartography analysis in syntax has dealt with wide range of syntactic phenomena. The functional categories in the le ft peripheral area of the cartography have their own discourse function. Based on the cartography analysis, this paper shows the possibility of occurrence of MoodP above FinP in the left periphery of clauses. MoodP bears the function of speaker’s mood of utterance concerning uncertainty. The uncertainty appears as a null category in the head position of MoodP. This category always occurs in interrogative sentences and licenses negative polarity items in those sentences by binding them. Conditional clauses also bear this null category in MoodP because they imply uncertainty concerning the truth value of thier propostion. The null category, bearing uncertainty, can license negative polarity items in the conditional clauses as well. This null category hypothesis can be applied to other syntactic phenomena which are closely related to licensing negative polarity items. 続きを見る

概要: This paper reveals that Japanese National Diet members including coalition parties’ members and opposition parties’ memb ers, local level politicians, and nonpoliticians provide different type of information during televised political interviews. The study at the center of this paper indicates that different types of questions by interviewers result in different type of information from interviewees. In modern post-truth politics, it is crucial for politicians to provide information to the general public. In particular, it is important of decision-makers to transfer high-quality information to voters and other citizens. The results of this study show that coalition parties’ members and nonpoliticians tend to provide more technical information during political interviews. Additionally, interrogative-word questions, those that start with the words “what,” “why,” “who,” “when,” “where,” or “how” are most likely to elicit technical information from interviewees. The study suggests that broadcast political interviews can provide useful information for voters especially during election campaigns. 続きを見る

概要: For any integer n≧3, let G be the maximal planar graph with n vertices and m=3n−6 edges, and, T1 and T2 be any two trees with n−1 vertices and n−2 edges each other. If G contains T1 and T2 then we define the following subgraphs G′ and G″ of G as follows. Let G′ be a graph obtained by deleting edges of T1 and T2. Furthermore, let G″ be a graph obtained by deleting isolate vertices of G′. In this paper, we consider the problem to determine whether there is a maximal planar graph G such that T1 and T2 are contained in G and G″ is simple and connected subgraph with n−2 edges obtained from G, in the 3≦n≦7 case. As a conclusion, we can obtain that the answer of the problem is “yes”. In this paper, we discuss the detail of our consideration as the following ⑴ and ⑵. ⑴ If n=7, T1 and T2 are star type trees as table 3.8 described below, and G is the maximal planar with 7 vertices and 15 edges as table 4.6 described below, then G can not contain T1 and T2 in the same time. ⑵ Otherwise, G can contain T1 and T2, and G″ which is simple and connected subgraph with n−2 edges obtained from G. 続きを見る

Force in the left peripheral field activates as force marker. However, this paper shows that Fin in the left peripheral field can operate as force marker and a verb moves up to there due to the force specification. It has been argued that V2 is related to feature specification in C (e.g.+F) and V-to-T movement is dependent on richness of inflection and tense. The framework presented here provides a straightforward account of V1, V2 phenomena in Germanic languages. English shows cyclic demise of V-to-C and V-to-T movement in its history.

A review of research on brand marketing as well as that on organizational psychology and the identity theory indicated that a corporate brand might be able to attract and orient customer contact employees to their organization. Further, certain processes at work enable individuals to incorporate elements of their organizational identity into their collective self. The mechanism of these processes can be explained by social identity, self-categorization, and self-regulation theories.

概要: Recently, the number of students who read the newspaper has been decreasing even though an increasing number of students access online news obtained through major research engines. With reference to newspapers in education, research on the use of electronic newspapers in order to adapt to the present situation is necessary. In the present paper, users’ perception and evaluation of articles in community-based electronic newspapers is examined. An online questionnaire survey was conducted for the users of KAHOKU Shimpo, which has a regional community in the area of Tohoku in Japan. Results showed that there are common criteria for users to evaluate articles of both online and paper. The result of users’ evaluation of top-shared articles indicated that users’ evaluations are not necessarily correspond to the general result of “share” by means of online communication. 続きを見る

概要: There are a lot of weirs for irrigation at rivers in Sumatra Island, Indonesia.
