Hemophilia is a rare X-linked recessive bleeding disease caused by a deficiency of blood factors VIII and IX for hemophilia A and B, respectively. Intracranial hemorrhage (ICH) is the most serious event in hemophilia patients and results in high rates of mortality and disability, especially in younger children, even though it occurs only 1-4% of this population. However, approximately 20-30% of hemophilia is sporadic and cannot be diagnosed at the time of ICH onset. Herein, we present two cases of intracranial hemorrhage in children with hemophilia without family history. Case 1 involved a seven-day-old neonate with severe hemophilia A. He was born via normal vaginal delivery at 37 weeks and 5 days. His Apgar score was 9 at 1 minute and 10 at 5 minutes. He was sufficiently healthy to be discharged home on day 5, but was brought to the emergency room on day 7 for nausea and a feeding disorder. His anterior fontanelle was bulging and a CT scan revealed a right subdural hematoma with a midline shift. He underwent surgical treatment for hematoma with craniotomy. The surgery was successful; however, a postoperative blood examination revealed high APTT. We initiated factor VIII and IX concentrate and fresh frozen plasma (FFP) infusion postoperatively, until severe hemophilia A was diagnosed. At the seven-year follow-up, he could walk independently, but exhibited moderate left hemiparesis and severe developmental delay. Case 2 involved a three-month-old infant with severe hemophilia B. He was born by caesarean section at 39 weeks and 3 days and was raised without any difficulties. At the age of 3 months, he was brought to the emergency room for vomiting and lethargy. He had right moderate hemiparesis, and a CT scan revealed a left intracerebral hematoma spreading from the frontal to the temporal lobe, with ventricular perforation. We suspected hemophilia due to a prolonged APTT, and he was administered FFP before the ventricular reservoir placement. The surgery was successful, and we continued infusing FFP for 8 days until we obtained factor IX concentrate. At the 1-year and 1-month follow-up, his right hemiparesis had recovered, but exhibited mild developmental delay. When a child has ICH, spontaneous ICH caused by coagulopathies such as hemophilia should be suspected, as well as an accidental head trauma or abuse. In the event of emergency surgery when coagulation factor concentrate cannot be prepared immediately, FFP may be used for perioperative coagulation management. [ABSTRACT FROM AUTHOR]

Grinding is a unit operation to reduce particle size by milling, and recently the demands for such operations have been increasing more and more. Computer simulation is effective in optimizing the grinding process and designing equipment, and the number of studies is increasing. To predict grinding results quickly with a low calculation load, it is useful to output the impact energy obtained from ball-only calculations as an indicator of grinding. We introduce how simulation can be used in grinding process analysis, including examples of reproducing ball behavior, predicting grinding results such as particle size distribution, and analyzing mechanochemical effects.

As harassment, such as power harassment and sexual harassment, in competitive sports has become a serious social problem in Japan in recent years, there is a need to develop educational approaches to protect the integrity of athletes. This study developed educational materials to promote awareness of harassment issues among top athletes and verify the effectiveness of these materials. To help athletes understand their behavior more objectively and to be more aware of what might be perceived as harassment, teaching materials on "sexual harassment" and "power harassment" situations were developed to educate them on perception differences. Then, a training session was conducted with top athletes to evaluate the teaching materials, and pre- and post-questionnaire surveys were conducted for individual and group events. This analysis revealed significant differences in the mean scores for "awareness of sexual harassment and power harassment" in both individual and group events. In addition, significant differences were found in "relevance of sexual harassment and power harassment to oneself" in the individual category. This suggests that these materials had raised athletes' awareness of the parties involved in harassment issues. [ABSTRACT FROM AUTHOR]

Phytoseiid mite species were surveyed on garden and wild plants in an experimental field in Japan. The above-ground part of the plants were collected from the field, and dried in the laboratory to collect phytoseiid mites from the plant-parts. When the plant-parts were dried on the bean leaflets rearing Thrips tabaci larvae, phytoseiid mites on the plant-parts moved to and remained on the leaflets during two-day treatment. Populations of Typhlodromips sessor and Neoseiulus makuwa were established when fed on T. tabaci. Then, the life history parameters of both species were examined in the laboratory. In comparison with the data from previous studies, the daily oviposition of both species was similar to that of Amblyseius eharai, Neoseiulus barkeri, and Neoseiulus cucumeris, and the survival rate during the development of both species was similar to that of N. barkeri. The mode of reproduction of T. sessor was confirmed by the experiment as parthenogenetic thelytokous reproduction. [ABSTRACT FROM AUTHOR]

The pressure measurement using a fiber optic prove hydrophone (FOPH) and the observation with a high-speed video camera have been conducted simultaneously to investigate the collapse of a laser-induced bubble near a rigid wall and the corresponding shockwave generation due to the bubble collapse. Prior to the experiment of the bubble collapse near a rigid wall, the experiment of a laser-induced bubble in infinite water has been conducted to check the applicability of the FOPH to the pressure measurement. The directivity of FOPH is evaluated by controlling a directional angle to the spherical shockwave and a distance from a collapsing bubble. The peak pressure Pmax obtained at each θ was normalized by the peak pressure Pomax obtained at θ = 0, and the calibration formula was obtained. Also, the peak pressure of the shockwave decays in proportion to the -1st power of the distance, which shows the characteristic of a spherical wave propagation. In the experiment of the collapse of a laser-induced bubble near a rigid wall, the bubbles collapse accompanying with the translation toward the wall. Then, the micro-jet penetrates the bubble surface toward the wall. By introducing a stand-off parameter γ, the peak pressure by the first collapse was evaluated. Due to the calibration of the directional angle and the distance, the peak value of the pressure of the shockwave takes a local minimum when γ is around 1. [ABSTRACT FROM AUTHOR]

In this study, the effects of two instructions, which suggested different levels of precision, namely, tell me roughly or exactly on recalling events were examined. The sample comprised 62 and 58 first-grade and fourth-grade children, respectively and 60 undergraduates. They were asked to recall a text describing a school sports day with one of the instructions that were given separately as a between-subject factor in study 1 and consecutively as a within-subject factor, which would enable the participants to compare the two instructions, in study 2. The results of study 1 revealed that the participants reported more coarse information for important units when employing exactly whereas they were more inclined to withhold unimportant information when employing roughly. In study 2, they provided verbatim information for important units when exactly was used and withheld relatively important information when roughly was used; however, children found this difficult. These results suggest that individuals regulate the level of precision depending on the context. The implications for forensic interviews are discussed. [ABSTRACT FROM AUTHOR]

It is well known that sports mouthguards(MG)are useful for the oral protection of contact sports participants. Soft-tissue injuries, broken teeth, bone fractures and brain concussions are all reduced in wearers of mouthguards participating in sports that involve impacts between players and/or sporting implements. For such purposes, the most important physical properties of the materials of sports mouthguards are the shock absorption characteristics for impact force. Sometimes, however, the designs of sports mouthguards can also be effective for avoiding oral injuries. A newly designed air-space type mouthguard(air MG)was developed for this purpose. Three types of air MG with air-spaces of 1.0, 2.0 and 3.0mm were designed, and seven specimens of each were made. A handmade steel ball-drop test apparatus was used to measure the shock absorption capacity. The best performance in reducing impact force was shown by the 3.0mm air-space specimen. The next experiment evaluated the efficacy of airducts of different diameters. Both the 1.0mm and 2.0mm air-spaces with a 5.0mm diameter air-duct showed good performance in reducing impact force (Tukey-Kramer test, p< 0.05). The results of these tests suggested that the air MG may be useful for reducing impact force. However, further study is needed for clinical applications. [ABSTRACT FROM AUTHOR]

Ball motions in a planetary ball mill with liquid media were simulated using the DEM. The distributions of ball impact energy were calculated from the simulation. Then，the cumulative value of the impact energy (E) and median of the impact energy at one collision (e1/2) were calculated. Grinding tests were examined and relationships between particle sizes and the specific impact energy multiplied by grinding time (Ewt*) were evaluated. At higher acceleration， particle sizes of ground powders decreased faster. However, from the viewpoint of the impact energy，the energy efficiency got worse. With increase of ball sizes, e1/2 increased but the number of collisions decreased. As results, using the smaller balls，particle sizes decreased faster and the energy efficiency was also better. The amount ofEwt required to obtain 0.5 pm mean diameter (Ewt*(0.5 pm)) was calculated for each test condition. The fitting curve was applied for the relation of Ewt*(0.5vs e1/2.

A new method to determine both the coefficients of particle and rolling friction in distinct element method (DEM) was proposed. The coefficients are two of the most important parameters which have great effect on particle behavior in DEM. However, it is difficult to determine the values of the coefficients, which is applicable to multiple behaviors, from an experiment. We proposed the method to determine the two coefficients uniquely so that two indicators correspond to experimental results. As the indicators of static and dynamic behaviors, the angle of repose and the discharge flow rate were adopted, respectively. The values of the coefficients which can represent both static and dynamic behaviors of particles were determined by means of the method. The particle behavior in a rotating drum at three different rotational speed was simulated by using the determined coefficients in order to verify the applicability of them to dynamic behavior of particles under various conditions. The simulated behaviors for spherical particles corresponded to the experimental ones. The determined coefficients by means of the proposed method could be applied to the behavior of spherical particles at all of the rotational speeds. On the other hand, the simulated behaviors for irregularly shaped particles did not correspond to the experimental ones, in particular at higher rotational speed. It would be because the rolling friction of irregularly shaped particles depends on the particle velocity in a rotating drum. [ABSTRACT FROM AUTHOR]
