    This paper proposes a concept of the task-oriented software synergy (TOSS) as a novel control method for anthropomorphic hands and a control system of multi-fingered hand that realizes TOSS. TOSS is able to perform various tasks with fewer inputs than conventional synergy by switching synergy for each task. By comparing TOSS with the conventional synergy, we show that TOSS gained higher contribution rate than the conventional synergy for writing task and smaller error of joint angle due to the effect of dimensional reduction. Moreover, we verified through physics simulation that the success rate of a task using TOSS with a few principal components is higher than conventional synergy based method. These results show that TOSS can properly perform various tasks with fewer inputs.

    The purpose of this study was to clarify the development pattern of batting imagery in youth baseball players. One hundred thirty-eight young baseball players (6–14 years old) were divided into 4 age groups. Tee and toss batting with a stationary tee stand and toss machine were used in the batting trials. In addition, the participants did an imagery task of hitting the optimal point of a ball where they wanted to impact it. To clarify the difference between the image trial and actual batting (tee and toss), the absolute error distance (AED) was calculated by subtracting the impact distance of the image trial from that of the actual batting. Two-way analysis of variance (4 age groups × tee and toss images) revealed that the AED was significantly lower in the 11- to 12-year-old players than in the 6- to 8-year-old players (p < 0.001). The relationships between the tee and toss images showed a significant correlation in all 4 groups (6–8 years old: r = 0.445, 9–10 years old: r = 0.495, 11–12 years old: r = 0.589, and 13–14 years old: r = 0.804; all groups: p < 0.001) and that tee and toss batting imagery appears unchanged as age increases. However, batting imagery seems to develop around 11-12 years old, and at the age group of 13-14 years old players are able to impact the same position on the bat regardless of the batting trials.

    We consider the distributed setting of N autonomous mobile robots that operate in Look-Compute-Move (LCM) cycles and communicate with other robots using colored lights (the robots with lights model. This model assumes obstructed visibility where a robot cannot see another robot if a third robot is positioned between them on the straight line connecting them. In this paper, we consider robot movements to be on a grid (integer plane) of unbounded size. In any given step a robot positioned at a grid point can move only to an adjacent grid point to its north, south, east or west. The grid setting naturally discretizes the 2-dimensional plane and finds applications in many real-life robotic systems. The Complete Visibility problem is to reposition N autonomous robots (starting at arbitrary, but distinct, initial positions) so that, on termination, each robot is visible to all others. The objective in this problem is to simultaneously minimize (or provide trade-off between) two fundamental performance metrics: (i) time to solve Complete Visibility and (ii) area occupied by the solution. We also consider the number of distinct colors used by each robot light. We provide the first O(max{D,N})-time algorithm for Complete Visibility in the asynchronous setting, where D is the diameter of the initial configuration. The area occupied by the final configuration is O(N^2); both the time and area are optimal. The time is randomized if no symmetry breaking mechanism is available for the robots. The number of colors used in our algorithm depends on whether leader election is required or not: (i) 17 colors if leader election is not required and (ii) 32 colors if leader election is required.

    This paper proposes a concept of the task-oriented software synergy (TOSS) for anthropomorphic hands and designs a control system of multi-fingered hand that realizes TOSS. By using TOSS, we can perform various tasks with fewer principal components than those of conventional synergies by switching synergy corresponding to each task. We show that TOSS can be realized with lower approximation error and higher contribution rate than the conventional synergy for a given task. Moreover, we verified through physics simulation that an adverse effect of dimensionality reduction is smaller than conventional synergy. These results show that, by using TOSS, we can properly perform various tasks with fewer inputs.

    The present study was conducted to analyze the visual behavior of volleyball players using a wearable camera, instead of the expensive eye trackers that have been employed to date. The position of the player's forehead, i.e. the direction of the line of sight, was estimated approximately from the images recorded by the camera (pilot studies 1 and 2). We then examined differences in the player's gaze shift patterns, ball pursuit time and initial spiker fixation when blocking the volleyball, as a function of experience in playing volleyball (main study). The results from pilot studies 1 and 2 indicated that the ball pursuit time from just after release of the ball by the setter and the time taken to fix on the spiker, i.e. the time between the blocker's eyes leaving the ball and shifting to the spiker, was measured as accurately by the wearable camera as by using an eye tracker. The main study indicated that gaze shift pattern was separable into “gaze shift” (volleyball players, 100% and general sports players, 47.8%) and “ball pursuit” types (general sports players, 52.2%) indicative of skills based differences. However, there was no detectable difference in the time when players shifted their sight from the ball, or in the time when they saw the spiker, according to skills based on prior volleyball experience. In conclusion, the present findings indicate that it is possible to estimate visual behavior during blocking tasks in volleyball using a less expensive wearable camera, rather than an expensive eye tracker.

    Crystals of allocinnamic acid having a melting point of 68 °C are monoclinic: space group P21/n with a = 10.157(4), b = 9.798(2), c = 15.770(4) Å, β = 91.35(3)°, and Z = 8. The structure was solved by direct method and refined to a final R value of 0.059 for 3832 reflections [I > 3σ(I)]. There are two independent molecules (A, B) in the asymmetric unit. The two molecules are hydrogen bonded through carboxylic acid groups [O1A···O2B 2.643(5) Å, O2A···O1B 2.629(5) Å]. Geometric differences between the two molecules are found in the torsion angle around the C(phenyl)–C(olefin) bond and the olefinic C=C bond length. In the high-resolution solid-state 13C NMR spectra resonances for the C2, C3, and C4 carbons are observed as doublet features in accordance with the conformational variations observed in X-ray crystallography.

    In the present paper the author tried to clarify the structure of volley-ball class from the viewpoints of form and teaching of skills of volley-ball. The data were collected by the use of V.T.R. in volley-ball classes for the first grade at A and B Senior High Schools for 8 school hours. And then they have been arranged by a Series of Time (i.e. Barnes's Motion and Time Study) to make clear (1) What basic elements the structure of volley-ball class consists of, and (2) through what exercises each skill of volley-ball is taught and how each skill is synthetically taught in actual class. The results are as follows : 1) At A High School, skills of volley-ball are analyzed into various basic one, and system-attired. and then synthesized so that students may obtain and develop each skill systematically through 8 school hours On the other hand, at B High School, such basic skills are repeatedly taught and exercised hot separately but organically. 2 ) The ways of the exercises of skills are considerably different in both schools. Especially at A School, skills are taught through the process of concentration and development so that students may master them automatically. 3) Judging from (1) and (2), the ways of the exercises of each skill which may be thought of as a mail object in each class, and the number how many times students play it are different. It is more remarkable that at B School 'toss' and 'attack' are not taught at all through 8 school hours. 4) The game was performed several times as a final part of volley-ball class at the sixth, seventh, all eight periods at both schools. But as a game may be thought of as the place where the students can estimate themselves whether or not they could sufficiently obtain skills of volley-ball, and where teachers themselves can reflect on the method of their teaching and exercises, it is very important for developing the skills of the students to decide when the game should be performed in the unit of volley-ball.

    A considerable amount of studies on the volleyball skills has been reported. However, the informations on the method of kinematographic analysis are quite scarce. Although the literature such as Ishiguro, Yamamoto, Takahashi, Miura, and Kawai are serving as the source of information in this particular area, the accumulated results may be still insufficient. Especially on the passing and spiking motions which should be one of the most fundamental skills in volleyball, there is no information available based upon kinesiological analysis. While players move unconsciously of their forms, it is of no practical use to give instructions about the body movements to hem while playing. Johnson insists that at least four factors are necessary to take into consideration as the variables of skills of an exercise, namely speed, accuracy, form and adaptability, upon an analysis of woodcutter contests. The present report intends to analyze the components in passing, tossing, and spiking in the sport of volleyball by use of kinematographic analysis, and to obtain some useful in formations in objectively instructing basic skills of volleyball.

    Background: Methylated catechin, one of the active ingredients in green tea, has been reported to ameliorate allergic reactions. We evaluated the efficacy of ‘Benifuuki' green tea, which contains O-methylated epigallocatechin-3-O-[3-O-methyl] gallate (O-methylated EGCG), in alleviating Japanese cedar pollinosis (JCP).
    Methods: The study was a double-blind, randomized, placebo-controlled trial. The subjects with JCP were randomly assigned to drink 700ml of ‘Benifuuki' green tea containing O-methylated EGCG or ‘Yabukita' green tea (not containing O-methylated EGCG) as a placebo every day from December 2007 through March 2008, which includes the pollen season. The primary outcome was the area under the curve (AUC) of symptom scores during the peak pollen season.
    Results: Fifty-one adults with JCP participated in the study. Twenty-six subjects were assigned to ‘Benifuuki' and 25 to ‘Yabukita'. The AUC of symptom score during the peak pollen season in the ‘Benifuuki' group was significantly smaller than in the ‘Yabukita' group for each of runny nose, itchy eyes, tearing, total nasal symptom score, total ocular symptom score, nasal symptom-medication score and ocular symptom-medication score. The total QOL-related questionnaire score for one week in the peak pollen season was significantly better in the ‘Benifuuki' group. Increase in the peripheral eosinophil count in response to pollen exposure was suppressed in the ‘Benifuuki' group. No adverse events were reported in either group.
    Conclusions: ‘Benifuuki' green tea containing a large amount of O-methylated EGCG reduced the symptoms of JCP and has potential as a complementary/alternative medicine for treating seasonal allergic rhinitis.

    Background: Recent studies have examined the effects of intranasal corticosteroids (INSs) in relieving the ocular symptoms of seasonal allergic rhinoconjunctivitis (SAR) and perennial allergic rhinitis. However, because most of these studies were based on subjective assessments by patients, the associated factors and mechanism of action are unknown.
    Methods: A single-center, randomized, double-blind, parallel-group study was carried out in which patients with SAR were randomly assigned to an INS mometasone furoate nasal spray (MFNS) group or to a placebo group and treated once daily for 4 weeks. Substance P concentrations in tears were measured, ocular and nasal symptoms were recorded by patients in an allergy diary, and findings were recorded by an ophthalmologist.
    Results: There was no significant difference between treatment groups in the mean change from baseline of substance P concentration in tears after 4 weeks of treatment, but the mean change tended to increase in the placebo group and tended to decrease in the MFNS group (P = 0.089). All ocular and nasal symptom scores, except eye tearing, were significantly lower in the MFNS group than in the placebo group. Furthermore, substance P concentrations were strongly correlated with ocular and nasal symptom scores.
    Conclusions: In patients with SAR, INSs tend to decrease the substance P concentration in tears, which is correlated with the severity of ocular and nasal symptoms.

    Background: Fluticasone furoate nasal spray (FFNS) is a glucocorticoid developed for the treatment of allergic rhinitis (AR). This is the first randomized clinical trial to assess the efficacy and safety of FFNS in Japanese children with perennial AR (PAR).
    Methods: In this multicentre, randomized, double-blind, placebo-controlled, parallel-group, phase III study, 261 children aged 6 to <15 years were treated with FFNS 55μg, once daily or placebo for two weeks. Nasal and ocular symptoms were rated by parents/guardians/patients in the patient daily diary. The primary endpoint was the mean change from baseline in the three total nasal symptom score (3TNSS). In addition, rhinoscopic findings were rated by the investigators as an efficacy measure. As a safety measure, adverse events and clinical chemistry and hematology were evaluated.
    Results: Mean change from baseline over the entire treatment period in 3TNSS was greater in the FFNS 55μg group compared with placebo, and the difference was statistically significant (p < 0.001). Significant improvements in rhinoscopic findings of swelling of inferior turbinate mucosa and quantity of nasal discharge were also observed. The total ocular symptom score (TOSS) was reduced significantly in the FFNS 55μg group, compared with placebo, in the second week in a subgroup of patients with baseline TOSS > 0. The incidence of adverse events was similar between FFNS 55μg (18%) and placebo (19%).
    Conclusions: Two-week treatment with FFNS 55μg, once daily is effective and tolerable in Japanese children aged 6 to <15 years with PAR.
