スポーツ ビジョン ノ トクセイ ト オウヨウセイ

We examined the influence and characteristics of vision training on sports vision. In addition, using free throw of basketball competition as an indicator, we conducted the experimental study about the applicability of vision training to improving competition. The outline of the obtained knowledge is as follows. 1.The transition of the total score of the sports vision measurement showed a significantly higher value in the training group than value in the control group. 2.No significant sequential change both in the training group and the control group was observed in the coefficient of variation of the total score of the sports vision measurement. 3.When classifying the training group into the upper group or the lower group by the total score of the sports vision measurement, the upper group showed a significantly higher value in the salivary α−AMY activity value after the sports vision measurement. In addition, the sympathetic nervous system activity index based on heart rate variability during sports vision measurement also turned out to have a tendency to show high value. 4.When classifying the training group into the upper group or the lower group by the total score of the sports vision measurement, the upper group showed a significantly lower value in the coefficient of variation of salivary α−AMY activity value before and after the sports vision measurement. 5.It was suggested that the deviation of the shot in the anteroposterior and lateral directions can be reduced by the vision training for those who have inexperienced basketball competition. It was suggested that vision training improves sports vision, and also is useful for the athlete with low competition level to improve the competitive performance. In addition, it was inferred that sports vision might fluctua te reflecting the intrinsic influences such as sympathetic activation and degree of attention caused by the response to the stimulus

In this study, we examined usefulness of α−AMY activity value in saliva as a non−invasive stress marker in the enduring exercise. In experiment 1, nine high school students participated in the measurement of the day−to−day variation and diurnal variation of saliva α−AMY activity value at rest. In experiment 2, seven adult male athletes participated in the measurement of α−AMY activity value in saliva during gradually increased or decreased exercise test. In Experiment 3, two adult males of identical twins and fraternal twins who specialize in long−distance run, we verified the constitutional impact on α−AMY activity value change in saliva during gradually increased or decreased exercise test. Summaries of knowledge obtained from these experiments are as follows. 1．A day change of α−AMY activity value in saliva at rest showed transition reflecting circadian rhythm. 2．Diurnal change for four days of α−AMY activity value in saliva at rest didn’t show significant change. 3．A strongly positive correlation was observed between α−AMY activity value in saliva and heart rate in endurance exercise. 4．The α−AMY activity value in saliva during endurance exercise changed reflecting the exercise intensity, but large individual differences were also observed. 5．From the ups and downs of α−AMY activity value in saliva of identical twins during endurance exercise, constitutional influence was little suggested. From the above results, α−AMY activity value in saliva was suggested to be useful as a non−invasive stress marker in enduring exercise. However, the change is observed to correspond to individual differences, and personal factors such as physical condition and characteristics of the subject seem to be related to, which will be the future work to verify

As for the physically handicapped person due to spastic type cerebral palsy, the difference of detraining period was verified for the impact on the lower extremity muscle strength. The obtained results are as follows. 1．The knee joint muscular strength was significantly enhanced by the detraining of three months. 2．The hip joint muscular strength was not significantly enhanced by the detraining of three months. 3．The muscular strength of the knee joint and the hip joint was weakened by the detraining of six months. From these results, it is suggested that the detraining period may effect on the lower limb muscle strength. It is also suggested that the effect of detraining may depend on muscle contraction style. These findings are not necessarily corresponded to the results of the previous study that were conducted to healthy people as a subject of the research. Therefore, further study is expected

Y.: Multi-view video coding using reference picture selection for free-viewpoint video communication

Free-viewpoint video communication lets the user freely change his/her viewing position and viewing direction while downloading and streaming a video content. One key technology of this communication is multi-view video coding. We propose a coding method using the group of GOP (GoGOP) structure, which is capable of decoding a view in low delay. This capability is quite essential to a communication application because of limited computing power of a terminal. The proposed coding method uses the hierarchical reference picture memory and multiple disparity vector memory to improve coding efficiency. We also demonstrate the efficiency comparing with the method that encodes views separately. 1

Patient safety incident reports related to traditional Japanese Kampo medicines: medication errors and adverse drug events in a university hospital for a ten-year period

Abstract Background Kampo medicine is traditional Japanese medicine, which originated in ancient traditional Chinese medicine, but was introduced and developed uniquely in Japan. Today, Kampo medicines are integrated into the Japanese national health care system. Incident reporting systems are currently being widely used to collect information about patient safety incidents that occur in hospitals. However, no investigations have been conducted regarding patient safety incident reports related to Kampo medicines. The aim of this study was to survey and analyse incident reports related to Kampo medicines in a Japanese university hospital to improve future patient safety. Methods We selected incident reports related to Kampo medicines filed in Toyama University Hospital from May 2007 to April 2017, and investigated them in terms of medication errors and adverse drug events. Results Out of 21,324 total incident reports filed in the 10-year survey period, we discovered 108 Kampo medicine-related incident reports. However, five cases were redundantly reported; thus, the number of actual incidents was 103. Of those, 99 incidents were classified as medication errors (77 administration errors, 15 dispensing errors, and 7 prescribing errors), and four were adverse drug events, namely Kampo medicine-induced interstitial pneumonia. The Kampo medicine (crude drug) that was thought to induce interstitial pneumonia in all four cases was Scutellariae Radix, which is consistent with past reports. According to the incident severity classification system recommended by the National University Hospital Council of Japan, of the 99 medication errors, 10 incidents were classified as level 0 (an error occurred, but the patient was not affected) and 89 incidents were level 1 (an error occurred that affected the patient, but did not cause harm). Of the four adverse drug events, two incidents were classified as level 2 (patient was transiently harmed, but required no treatment), and two incidents were level 3b (patient was transiently harmed and required substantial treatment). Conclusions There are many patient safety issues related to Kampo medicines. Patient safety awareness should be raised to prevent medication errors, especially administration errors, and adverse drug events in Kampo medicine
