In massed start bicycle races, riding in a group to avoid air resistance is profitable for racing cyclist to save their energy consumption. In this study, we estimated cyclists' power output and analyzed the relationship to the group size in a national championship of track cycling points race. The results show that the average velocity of the group increased as the number of riders in a group increased to some extent, but the average velocity of the large group decresed as the size of the group increased. These results suggest that the small groups are formed by cyclists intended to raise the pace and, on the other hand, the large groups are formed to save energy cunsumption by cyclists intended not to raise the pace.

<p>The present study investigated the features of the motivation at return to work in EY (Early Years) through the comparison of the UK & Japan, which had opposite direction in a recent policy reform of EY settings. I set the Five groups of 43 returners (13 Nursery Returners & 5 Other occupations Returners in Japan, 5 Nursery Returners, 6 Other occupations Returners, & 14 Returner applicants in England) and collected interview data. The text mining analysis of each group and compared with them chiefly focused on the words that co-occurred with 'Work', and got to 3 findings about the features of Japanese EY returners; 1. Their priority was their own children, the same as Japanese returners in other occupations. 2. They had an ambivalent attitude for their EY qualification. 3. The ratio of the negative relations between "work/working" and "I/myself" was higher. These tendencies regarded as the relation with the lower-leveled professionalism, and a poorer employment practice in part-time working in Japan EY facilities.</p>

Objectives We investigated the 5-year disease-related mortality risk, including that associated with neoplasms, mental/behavioral/neurodevelopmental disorders, and diseases of the circulatory system and respiratory system,in ambulatory frail Japanese older adults.Methods We retrospectively analyzed long-term care and health insurance claims data in this cohort study performed between April 2012 and March 2017. The primary outcome was mortality, and the secondary outcome was care-need level decline. Risk factors were determined based on the International Statistical Classification of Disease and Related Health Problems, 10th Revision codes, hospitalization, and institutionalization. The study included 1,239 ambulatory frail older adults newly certified as needing Support-Level care at baseline (April 2012-March 2013) across three Japanese municipalities.Results Of the 1,239 participants, 454 (36.6%) died. Neoplasms (hazard ratio [HR] 2.69, 95% confidence interval [CI] 1.97-3.68) or respiratory system diseases (HR 1.62, 95%CI 1.26-2.08) were independently associated with mortality. Mental/behavioral/neurodevelopmental disorders (HR 1.39, 95%CI 1.17-1.66) or diseases of the respiratory system(HR 86, 95%CI 75-99) were independently associated with care-need level decline.Conclusions This study suggests that neoplasms or respiratory system diseases were associated with a high mortality risk and that mental/behavioral/neurodevelopmental disorders were associated with care-need level decline among ambulatory frail older adults. Optimal disease management and effective long-term care are important to delay the onset of these events in older adults certified as needing Support-Level care.

We, the Society for the Research of Modern Culture of Kobe, have been studying the cultural formation of the port city of Kobe from various aspects. In this paper( which will form the first part of our whole research) we deliver a report on the trend of movies, theater, performing arts, fine arts and photography in the city, by scrutinizing a series of articles, Zassô-en, written by the Kobe correspondents, in the newspaper Kobe Furoku, Osaka Asahi Shimbun, issued in 1923. Through the Zassô-en articles we can see not only various incidents reported by the correspondents but also their love for their hometown, which encouraged them to plan and carry out diverse cultural and artistic events in the town. We can also find the trend of the picture houses and moviegoers in Shinkaichi, Kobe, in those days, especially the way the entrepreneurs attracted people. Concerning the theater, the articles tell us that the things gladly accepted then were comedy and Shinkokugeki.

Potential games form a class of non-cooperative games where the convergent of unilateral improvement dynamics is guaranteed in many practical cases. The potential game approach has been applied to a wide range of wireless network problems, particularly to a variety of channel assignment problems. In this paper, the properties of potential games are introduced, and games in wireless networks that have been proven to be potential games are comprehensively discussed.

This paper describes a design method of a friction reducer device using a loading cam to suppress unstable vibration. Nonlinear simulation and energy analysis of numerical solutions demonstrates that destabilization is caused by the large phase difference between the slipping velocity in the translation direction and that in the rotation direction. It was found that similarly unstable vibration occurs in various structures using wedge rollers with translational and rotational motion. The analytical equation could be simplified by focusing on the motion factor that affects the slip velocity of the power transmission surface, which is the factor of vibration. Consequently, the design method for suppressing vibration could be expressed by a mathematical formula. This equation is validated by using the results of experiments conducted in the previous work of the current authors. Furthermore, from this equation, we proposed that vibration could be suppressed by the parameter balance of the power transmission device without using damping. The power transmission surface slips when a quick torque is input and damping is used. The proposed design can handle a quick torque response and reduce the weight of the reducer. Specifically, the shape of the wedge roller is made lighter, so that the moment of inertia of the roller is not lowered, or the wedge roller is set as a small roller.

This clinical study was conducted to investigate the safety and effect of D-psicose on postprandial blood glucose levels in adult men and women, including borderline diabetes patients. A randomized double-blind placebo-controlled crossover experiment of single ingestion was conducted on 26 subjects who consumed zero or 5 g of D-psicose in tea with a standard meal. The blood glucose levels at fasting and 30, 60, 90, and 120 min after the meal were compared. The blood glucose level was significantly lower 30 and 60 min after the meal with D-psicose (p<0.01, p<0.05), and a significant decrease was also shown in the area under the curve (p<0.01). The results suggest that D-psicose had an effect to suppress the postprandial blood glucose elevation mainly in borderline diabetes cases. A randomized double-blind placebo-controlled parallel-group experiment of long-term ingestion was conducted on 17 normal subjects who took 5 g of D-psicose or D-glucose with meals three times a day for 12 continuous weeks. Neither any abnormal effects nor clinical problems caused by the continuous ingestion of D-psicose were found.

RTK-RAS-MAPK systems are major signaling pathways for cell fate decisions. Among the several RTK species, it is known that the transient activation of ERK (MAPK) stimulates cell proliferation, whereas its sustained activation induces cell differentiation. In both instances however, RAS activation is transient, suggesting that the strict temporal regulation of its activity is critical in normal cells. RAS on the cytoplasmic side of the plasma membrane is activated by SOS through the recruitment of GRB2/SOS complex to the RTKs that are phosphorylated after stimulation with growth factors. The adaptor protein GRB2 recognizes phospho-RTKs both directly and indirectly via another adaptor protein, SHC. We here studied the regulation of GRB2 recruitment under the SHC pathway using single-molecule imaging and fluorescence correlation spectroscopy in living cells. We stimulated MCF7 cells with a differentiation factor, heregulin, and observed the translocation, complex formation, and phosphorylation of cell signaling molecules including GRB2 and SHC. Our results suggest a biphasic regulation of the GRB2/SOS-RAS pathway by SHC: At the early stage (<10 min) of stimulation, SHC increased the amplitude of RAS activity by increasing the association sites for the GRB2/SOS complex on the plasma membrane. At the later stage however, SHC suppressed RAS activation and sequestered GRB2 molecules from the membrane through the complex formation in the cytoplasm. The latter mechanism functions additively to other mechanisms of negative feedback regulation of RAS from MEK and/or ERK to complete the transient activation dynamics of RAS.

Diabetes mellitus (DM) is associated with an increased incidence of cardiovascular events and an elevated prevalence of sarcopenia. However, the relationship between cardiovascular events and sarcopenia in patients with DM remains unclear. This study examined this relationship and investigated the predictors of cardiovascular events in this population.This study enrolled 161 patients with DM and no history of cardiovascular diseases who were admitted to our hospital for the treatment of DM between September 2012 and December 2015. Patients were divided into sarcopenia and non-sarcopenia groups, and were followed until March 2019. The primary endpoint was major adverse cardiovascular events (MACE).The mean age was 65.9 ± 1.8 years old and the mean follow-up period was 4.1 ± 0.8 years. The log-rank test indicated that MACE differed significantly between the two groups (P < 0.0001). Multivariate Cox hazard analysis identified the cardio-ankle vascular index (CAVI) and handgrip strength as independent predictors of MACE (hazard ratio [HR] = 1.18, P = 0.039; and HR = 0.70, P = 0.016, respectively).Handgrip strength is an indicator of sarcopenia in diabetic patients, and together with CAVI it was independently associated with the incidence of MACE. This suggests that the handgrip strength test might be useful in the management of patients with DM at high risk of cardiovascular outcomes.

Population loss, the movement of young and middle aged people into occupations outside of agriculture, and the aging of LPG workers had been conspicuous in the rural areas of southwest Thuringia in former East Germany even before reunification. Aging of agricultural workers and acquisition of side jobs by members of farm households, processes similar to those occurring in West Germany and other industrial countries, had already begun. We investigated the employment situation in one particular village close to the former east-west border. Here, some young people were able to continue in their old occupations in the East even after reunification, while those who lost their jobs looked for employment in Bavaria, in former West Germany. They too often found occupations in which they could use their previously learned skills. The local LPG, on the other hand, was turned into a cooperative, which rehired for the most part young skilled workers, while the older generation was let go and went into retirement. There are now only two independent farms and one farmer who has rented his land out to a Bavarian lessee; all other land is rented by the local cooperative. In spite of the political changes the occupational structure of the area, agriculture with subsidiary employment-multiple job-holding farming-remains basically unaltered. We suggest that the equal division inheritance system, leading to small scale farms, and the existence of traditional manufacturing industries, etc., conditions that distinguish this region from the North of former East Germany, have sustained this structure. The location, close to the former border and resulting employment opportunities in the West, that became available with reunification, probably provide significant support for it. The rural area of southwestern Thuringia should thus be understood as having a character which is markedly distinct from that of the North of former East Germany.
