First, we discuss about requirements for humanoid robots of Japan. Here, Japanese dance is one of important Japanese cultures. Also, there are many people unfamiliar with Japanese dance in other countries. If they hope to learn Japanese dance, it is very important to instruct such people in Japanese dance. There have been several studies about the system for imitating human dances by using a robot. In this paper, we discuss the availability of robots for the instruction of Japanese dance. Typically, a classical Japanese dance is composed with fluent motions. Therefore, a robot needs to shift the center of gravity smoothly in Japanese dancing. In such a case, we found that ‘Suri-Ashi’ motion was effective. In this study, we focused on the realization of ‘Suri-Ashi’ motion. We researched about ‘Suri-Ashi’ motion from various points. Especially, we investigated points for implementing ‘Suri-Ashi’ motion to a miniature humanoid robot. Finally, we carried out experiments of dexterous motions in Japanese dancing by using a miniature humanoid robot.

The gastrointestinal motility effects of endogenous incretin hormones enhanced by dipeptidyl peptidase-IV (DPP-IV) inhibitors have not yet been sufficiently investigated. The aim of this study was to determine whether single pre-prandial sitagliptin, the DPP-IV inhibitor, administration might have an effect on the rate of liquid gastric emptying using the 13C-acetic acid breath test. Methods Ten healthy male volunteers participated in this randomized, two-way crossover study. The subjects fasted for overnight and were randomly assigned to receive 50 mg sitagliptin 2 hours before ingestion of the liquid test meal (200 kcal per 200 mL, containing 100 mg 13C-acetate) or the test meal alone. Under both conditions, breath samples were collected for 150 minutes following the meal. Liquid gastric emptying was estimated by the values of the following parameters: the time required for 50% emptying of the labeled meal (T1/2), the analog to the scintigraphy lag time for 10% emptying of the labeled meal (Tlag), the gastric emptying coefficient and the regression-estimated constants (β and k), calculated by using the 13CO2 breath excretion curve using the conventional formulae. The parameters between the 2 test conditions were compared statistically. Results No significant differences in the calculated parameters, including T1/2, Tlag, gastric emptying coefficient or β and k, were observed between the 2 test conditions. Conclusions The present study revealed that single-dose sitagliptin intake had no significant influence on the rate of liquid gastric emptying in asymptomatic volunteers.

Background/Aims The administration of liquid nutrients to patients is often accompanied by complications such as gastroesophageal reflux. To prevent gastroesophageal reflux, high-viscosity liquid meals are used widely, however, it still remains controversial whether high-viscosity liquid meals have any effect on the rate of gastric emptying. The present study was conducted with the aim of determining whether high-viscosity liquid meals had any effect on the rate of gastric emptying and mosapride might accelerate the rate of gastric emptying of high-viscosity liquid meals. Methods Six healthy male volunteers underwent 3 tests at intervals of > 1 week. After fasting for > 8 hours, each subject received one of three test meals (liquid meal only, high-viscosity liquid meal [liquid meal plus pectin] only, or high-viscosity liquid meal 30 minutes after intake of mosapride). A 13C-acetic acid breath test was performed, which monitored the rate of gastric emptying for 4 hours. Using the Oridion Research Software (β version), breath test parameters were calculated. The study parameters were examined for all the 3 test conditions and compared using the Freidman test. Results Gastric emptying was significantly delayed following intake of a high-viscosity liquid meal alone as compared with a liquid meal alone; however, intake of mosapride prior to a high-viscosity liquid meal was associated with a significantly accelerated rate of gastric emptying as compared with a high-viscosity liquid meal alone. Conclusions This study showed that high-viscosity liquid meals delayed gastric emptying: however, mosapride recovered the delayed rate of gastric emptying by high-viscosity liquid meals.

Although the mutually complementary network of wired and wireless was studied as an object for home houses and the result was got, adaptation evaluation was tried for it to small-scale buildings, such as a school building, this time. Consequently, it found out that the mutually complementary network of wired and wireless had the possibility of adaptation also at a small-scale building. In the home house, the performance of a mutually complementary network obtained 96.0% by the case of 70.0% of wired-communications performances, and 80.2% of wireless-communications performances. However, it becomes 70.6% and a communication performance is bad at a small-scale building. As the countermeasure, it found out utilizing the wireless-communications function of a stairs part positively this time.

Purpose: Few reports have been made on the therapeutic effects as well as pathological features of an antithrombin preparation in patients diagnosed with septic disseminated intravascular coagulation (DIC) by the diagnostic criteria for acute DIC. Materials and Methods: A total of 88 sepsis patients who had received inpatient hospital care during the period from January 2000 through December 2008 were divided into two groups, an antithrombin group and a non-antithrombin group, to study the outcomes. Furthermore, the relationship between sepsis-related factors and DIC in 44 patients was studied. Results: The antithrombin group contained 34 patients, and the non-antithrombin group contained 54 patients. The outcomes were significantly better in the antithrombin group. The levels of protein C were low in DIC patients. Conclusion: Our results suggest that early administration of antithrombin might improve outcomes of septic DIC patients in the diagnostic criteria for Japanese Association for Acute Medicine acute DIC.
