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 left 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 appearsasa null category in the head position of MoodP. Thiscategory alwaysoccursin interrogative sentencesand licensesnegative polarity itemsin those sentencesby 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 itemsin the conditional clausesaswell. 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’ members, 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: The purpose of this research is to demonstrate to what degree lexical information, visual information, and English-Japanese translation contribute to the English learners’ understanding of cross-culture in the framework of Relevance Theory. We construct two types of questionnaire asking 38 English learners about their existing knowledge of “How pure maple syrup is made,” and about how much they understand its production process at the four stages. We conclude that lexical information, visual information, and English-Japanese translation make positive influences on learners’ cross-cultural understanding by satisfying the Communicative Principle of Relevance. 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

概要: Interactive Evolutionary Computation (IEC) is an attractive method that searches media contents suited to each user’s preference and feelings. However, shortage of evaluation time caused of human user’s fatigue remains as a severe problem. A previous study proposed Continuous Evaluation-based IEC which makes the continuous evaluation task over several days. This study conducted an experiment for searching parameters of good voice for each user based on the idea of Continuous Evaluation-based IEC. Creation of voice was performed by using a free software UTAU. Experimental results showed successful increase in fitness values. 続きを見る

概要: The enzyme-food contained abundant functional ingredients, i.e., polyphenols, dietary fiber, and indigestible dextrin. The enzyme-food indicated high antioxidant activity and suppression of AGE (glycated protein) formation, which is thought to be responsible for the pathogenesis of various lifestyle diseases. The feeding of enzyme-food in rats suggested that the possibilities of body fat reduction, improvement of bowel movements, and improvement of carbohydrate and lipid metabolism. So the products commonly called ‘enzyme-foods’ may be beneficial for health maintenance because of functional ingredients, not food-enzyme, contained in them. 続きを見る

概要: In a non-thermal food processing system utilizing underwater shockwaves, there is a possibility that copper electrodes dissolved in water has a bad influence on human bodies. However, as far as the authors know, the water contamination of the non-thermal food processing system has not been investigated in past studies. For this reason, in this paper, we discuss the copper contamination in the non-thermal food processing system. To evaluate the copper contamination, we conducted the experiments using a water examination device for 100 samples. The experiment revealed that the copper concentration in the water of the pressure vessel was 0.33 mg/L at 17.5 degrees Celsius. 続きを見る

概要: To achieve the high quality graphene by molecular beam epitaxy (MBE), we previously obtained the suggestions that appropriate interaction between growth material and substrate is needed for the epitaxial growth of the graphene although inert surface is favorable for the substrates. Thus, we investigated MBE growth of graphene on the buffer layer (SiC(0001) 6√3x6√3R30°), whose atomic arrangement is the same as the graphene although its interaction is expected to be stronger than that of graphene because some carbon atoms of the buffer layer bond with underlying Si atoms and form electric dipoles by the charge inhomogeneity. Then, we achieved the epitaxial growth of graphene and the mobility value of 194cm2/V•s was obtained. This value is the highest value for the MBE-grown graphene. 続きを見る

概要: Randomness tests included in NIST test tool are not independent each other, i.e., the distributions followed by p-value of each test item are not independent. Even if each test item has no problem, the fact makes it difficult to derive the significance level of the test tool as whole items or to introduce a rational criterion for results of the tool. In this paper, we propose a method to solve this problem. The method transforms the distribution followed by each test item’s p-value to the standard normal distribution and assumes that the joint distribution after transformation is a multidimensional normal distribution. Diagonalizing to the joint distribution, the distribution of each test item's p-vale becomes independent each other. In addition, we evaluate this method numerically. 続きを見る

Using reservoir computing approach, which now becomes a popular tool in machine learning field, we estimated cross-prediction errors between different segments of time-series. These errors are considered as a measure of non-similarities between different segments. Then, multidimensional scaling was used to obtain a reduced representation of relational patterns among segments. 続きを見る

In our previous work, we have evaluated the network performance of our Message Suppression (MS) method for Vehicular DTN. In this paper, we consider a threshold-based adaptive method for MS in Vehicular DTN. We use delay and replicated bundle message as evaluation metrics. From the simulation results, we observe that our proposed method decreases the replicated bundle messages. 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. 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 set of puzzles concerning the patterns of the phonoma is explained as a consequence of the analysis which admits gradual loss of verb attraction to Fin. 続きを見る

Legislative reforms are spreading in Japan based on the situation within the prefectures,and bring about positive results encouraging citizen’s participation. Local legislative reforms should be advanced based on the awareness that these are means and not the goal. Local legislatures, as representative bodies, are expected to form better decentralization in cooperation with their residents. 続きを見る

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.Finally,the importance of human development programs for customer contact employees has been discussed. 続きを見る

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: Accurate estimation method of the vibration response for a mechanical system using Molecular dynamics method (MD) is considered. This study focuses on the MD modeling for estimating energy dissipation in Manganese-based alloys under vibration. The phenomenon of energy dissipation in metal is caused by internal friction. In manganese-based alloys such as M2052 alloy, internal friction occurs by the formation of twins in the material under external force. In this paper, the result of experimental modal analysis for obtaining values of natural frequency and damping ratio of M2052 plate is reported. In addition, the development of a large-scale MD simulator for estimating of displacement and velocity of atoms in pure Manganese single crystals under a very low temperature is investigated. 続きを見る

概要: Hall measurement is useful to investigate basic electronic properties of semiconductor wafers. Since the invention of the strong permanent magnets, Hall measurement systems using permanent magnets have been commercially available. However, these systems include too many functions and therefore are too expensive for single laboratory use. We propose here a very simple Hall measurement system with a neodymium permanent magnet at low cost. Using this system, electron density and mobility in a Si-doped AlGaAs/GaAs single heterostructure were measured. Obtained results are comparable to those found by using the commercially available system. 続きを見る

概要: In this research, the authors propose an extension to information diffusion game with revealed users’ preferences. An information diffusion game consists of a set of external players (interested parties), and a network of users (vertices). Our approach differs from the literature in two aspects: first, unlike the cancelled-out assumption in Alon et al. (1), each vertex has its own preference regarding the information released by the players, and will take the most preferred one. Second, instead of selecting only one vertex as the seed at the initial stage, the players are allowed for a more general strategy, i.e., multiple selections.Two experimental studies on the existence of pure Nash equilibria with this novel algorithm are conducted by an application called IDG (Information Diffusion Game) simulator, which is developed in Python. 続きを見る

概要: The piezoelectric air pump is a thin, compact, real silent, non-vibration, and lightweight. In this study, we developed the blood pressure (BP) monitoring system, based on the finger volume-oscillometric method, using the piezoelectric air pump. Firstly, Pumping characteristics were experimentally investigated. Secondly, the simultaneous BP measurement was performed for one healthy male (age: 22 years old) using the electronic sphygmomanometer and the prototype system. A load pressure over 200 mmHg for BP measurement were achieved with an applied voltage of 15 Vpp and a driving frequency of 23.8 kHz ~ 24.2 kHz. The 4.989 mmHg/s pressurizing speed was controllable by the pulse frequency and delay time. Mean blood pressure and systolic blood pressure were achievable in the finger photoplethysmogram with the cuff. Future work will focus on improvement of the control method for the linear load pressure increasing and the calibration pressure sensor for the high accuracy BP measurement. In conclusion, these findings suggest that it is possible to measure BP with real silent and non-vibration using a piezoelectric air pump in the finger. 続きを見る

概要: The aim of this study is to compare the heart rate (HR) derived from electrocardiogram (ECG) with the pulse rate (PR) derived from the green light ear photo-plethysmogram (PPG) using an earphone. We developed a compact device that the PPG sensor comprising a green LED and phototransistor was embedded in the earphone. The weight of device was 8.8 g. In 10 subjects, simultaneous measurements of ECG, and green light (525 nm) PPG from the front of tragus were made at the following treadmill speeds: 0, 2, 4, 6, 8 km/h. During walking (2, 4 km/h), the results showed that the PR derived from the green light PPG from the ear significantly related to HR derived from ECG (r = 0.98). In addition, the limit of agreement in Bland-Altman plots between these indices were ± 3.95 (1.96 SD) bpm. In conclusion, these findings suggest that the green light ear PPG using earphone might be practical measurement for monitoring HR during walking. 続きを見る

The Kansei retrieval agent model imitates the sensitivity of each user by optimization of fuzzy reasoning parameters. Previous studies have verified optimization of fuzzy rules of fuzzy inference and learned user evaluation criteria. Therefore, in this research, considering long-term use of this system, we verify the optimization performance of the Kansei retrieval agent model when many data are presented to users by numerical simulation. As a result, it is shown that the proposed method is effective from the viewpoint of user evaluation criteria learning. 続きを見る

概要: Faced with a shortage of the certifying physician of laparoscopic surgery, more effective training environment has been expected by the advising doctors. This study proposes the training system, which comprises one desktop computer, a web camera, and two lab-made forceps control devices. In order to make the fundamental training program of this system, both the forceps operation and the camera image while a skilled surgeon sutured the enteric canal model were recorded. The system gives a trainee the virtual experience of suturing the enteric canal model in a training. This paper introduces the system structure and the functions of the training system. 続きを見る

概要: Electrical discharges within lubricating films were investigated using a high-speed camera. Such discharges are typically observed in camera images as white flashes, or “white points”. These white points sometimes generate black pits, or “black points”, and some black points may allow electric current to flow. This paper presentssix patterns of white and black points, and compare the mpedances around the white and black points. 続きを見る

概要: A novel optical detection system was developed to achieve real-time and simultaneous monitoring of dissolved oxygen (DO) quenched-fluorescence and materials movement induced-beam deflection at a vicinity of an aquatic plant surface. A laser beam of 470 nm was passed through the vicinity of the aquatic plant in a culture dish filled with a culture solution containing 10-6 M fluorescent Tris (2, 2'-bipyridyl) ruthenium (II) chloride. Deflection of the laser beam and fluorescence excited by the laser were recorded simultaneously. Experimental results showed that only a little ruthenium complex might be adsorbed on the aquatic plant. Also, romoving DO for obtaining fluorescence intensity without DO was studied. It was demonstrated that the optical detection system could be used for real-time in situ monitoring of the DO-quenched fluorescence and materilas movement-induced beam deflection at the same time. 続きを見る

概要: Normally dielectric relaxation amplitudes are increased with decreasing temperature. However, some host-guest systems, such as hydrated proteins and hydrated porous media, exhibit anomalous temperature dependence where relaxation amplitude is decreased with decreasing temperature. In order to explain this anomalous dependence, I developed simplified model which consists of polar guests and a host with numerous connecting sites on its surface. Dielectric relaxation amplitude calculated from the model exhibits Onsager type normal temperature dependence in high temperature regime and Arrhenius type anomalous temperature dependence in low temperature regime. According from this model, the anomalous temperature dependence is explained as antiparallel dipolar-dipolar correlation intermediated via host. 続きを見る

概要: This paper focuses on the design method for improving efficiency of switched reluctance generator (SRG) and has a detailed discussion. It also contains the details of corresponding theories and simulation. In order to improving the efficiency of SRG, the existing SRG is analyzed with a finite element method software ANSYS, and the inductance data is obtained for various conditions. The six kinds of inductance curve’s shapes have been considered based on the inductance data of existing SRG. And a nonlinear simulation model using look-up table is made to calculate the efficiency of SRG for different inductance curve’s shapes. The inductance curve’s shape which can make the SRG having the highest efficiency is identified as a target inductance curve’s shape for the future detailed optimization design. 続きを見る

概要: When designing a power electronics equipment such as rectifiers and inverters, it is indispensable to calculate power loss of power semiconductors for estimation of power conversion efficiency, which influences mounting and cooling design of the equipment. In this paper, new approach for power loss calculation of power semiconductors based on Impulse Model is proposed. Proposed method is achieved by MATLAB-Simulink, and then the precision of the method is compared with that of a conventional loss calculation way. As a result, it is proved that the proposed method is practical. 続きを見る

概要: There is a consensus in public health professionals that prevention of long-term care in community-dwelling older people is one of the most urgent national issues in the modern aging society. Previous studies suggest that daily physical activity in midlife and old age can be helpful to prevent many disieases including diabetes, metabolic syndrome, some types of cancers, cardiovascular diseases, and dementia. Because these diseases are considered as potentioal etiologies of long-term care, daily physical activity is also expected to reduce the risk for long-term care, and thus, serve as a modifiable protective factor useful in the primary prevention of long-term care. However, knowledge regarding effective exercise regimen for the prevention of long-tem care has been still limited. The present research project was performed in the 2015-2016 academic years as a part of on-going examination for pursuing the effective exercise regimen. The specific aim of the present project was to compare changes in the circulating level of biomarkers associated with the preventive effects of exerise for long-term care in middle-aged and older men during two modarate exercise formats. This paper provides a brief summary for the project. 続きを見る
