KINEMATIC STUDY ON SEOI-NAGE, TECHNIQUE COMPARISON OF PLAYERS WITH OR WITHOUT ELBOW JOINT INJURIES

The purpose of this study is to clarify how to apply Seoi-nage to reduce the occurrence of injuries in elbow joints. Five participators were male college judo athletes, one as the Uke (receiver) and other four as Tori(Thrower), two of them with pain in elbow and other two without pain. The result shows that the players without pain in elbow flexed the elbow joints greatly and lifts the Uke by not bend the hip joint too much. Two considerations about the players(Tori) with pain in elbow. 1) The movement of Nagekomi in elbow joints was different from the Uchikomi. Therefore, it assumed that great load put on his elbow joints. 2) Hip joint bends after contacting with Uke and the upper body bends and throw with the power of the arm. In conclusion, the player who uses less strength of the lower extremities instead of the strength of upper body, which might cause injury

BIOMECHANICAL STUDY OF SEOI-NAGE IN JUDO - INFLUENCE OF ELBOW\u27S PAIN ON MOTION -

The aim of this study is to clarify Seoi-nage technique for reducing injuries in elbow joints. Uchikomi and Nagekomi were used as the trials. Two judo athletes with pain in elbow and three athletes without pain in elbow were instructed to perform the Seoi-nage as Tori. Strain gauge sensors were set in a judo cloth to measure the force applied by Tsurite (hand grasping the Eri). The results were observed as the follows: i) The athletes without pain applied a large force towards the throwing direction by the internal-rotation of shoulder. ii)In athlete with pain, the force direction was not towards throwing direction, but towards the left rotating side. The group without pain had an ideal movement of applyingSeoi-nage. On the other hand, thegroup with pain did not apply kuzushi, but generate force to throw the Uke by putting flexing the trunk with external-rotation position of the shoulder

Low dose RAI ablation

Outpatient ablation therapy with low-dose radioactive iodine (RAI) is applied to non-low-risk papillary thyroid cancer patients due to a chronic shortage of inpatient RAI treatment wards in Japan. We used the maximum dosage available for outpatient therapy of 30 mCi of RAI for ablation and diagnostic (Dx) whole-body scintigraphy (WBS). This study aimed to examine the significance of the second dose of 30 mCi. DxWBS was performed 6 months after ablation, and assessment of success or failure was performed 12 months after ablation. A second WBS was performed in the remaining RAI accumulation cases in the neck on DxWBS. The criteria for successful ablation was negative cervical accumulation on WBS, thyroid stimulating hormone-suppressed thyroglobulin (sup-Tg) below 1.0 ng / mL, and no increase in thyroglobulin antibody (TgAb) level. At the time of DxWBS, 35 / 68 cases met the successful criteria, and 45 cases achieved success at assessment. Sup-Tg values decreased significantly after ablation and decreased further after DxWBS in successful ablation cases, whereas those were not changed in ablation failure cases. Findings indicated that RAI used in DxWBS had therapeutic effects. It makes sense to use 30 mCi for DxWBS, given the current difficulty of inpatient ablation therapy with high-dose RAI

Developing a Learning Material to Understand and Explore Solar Eclipses as a STEM Topic

We propose a learning material for high-school students to understand the mechanism of solar eclipses and explore them from various viewpoints as a STEM topic. The purpose of this material is not to predict solar eclipses accurately, but the prediction error is small, which may provide the students the value of our material. In the next Course of Study, a new subject called the explorations in Math and Science will be launched. We expect that our material can be used there.本研究は，JSPS科研費JP17H00820の助成を受けたものである

CRADA No. NFE-10-02715 Assessment of AFA Stainless Steels for Tube Products in Chemical Processing and Energy Production Applications

Oak Ridge National Laboratory (ORNL) and Carpenter Technology Corporation (Carpenter) participated in an in-kind cost share cooperative research and development agreement (CRADA) effort under the auspices of the Energy Efficiency and Renewable Energy (EERE) Technology Maturation Program to assess material properties of several potential AFA family grades and explore the feasibility of producing alumina-forming austenitic (AFA) stainless steels in tubular form needed for many power generation and chemical process applications. Carpenter's Research Laboratory successfully vacuum melted 30 lb heats of seven candidate AFA alloy compositions representing a wide range of alloy content and intended application temperatures. These compositions were evaluated by ORNL and Carpenter R&D for microstructure, tensile properties, creep properties, and oxidation resistance. In parallel, additional work was directed toward an initial tube manufacture demonstration of a baseline AFA alloy. Carpenter successfully manufactured a 10,000 lb production heat and delivered appropriate billets to a partner for extrusion evaluation. Tube product was successfully manufactured from the baseline AFA alloy, indicating good potential for commercially produced AFA tubular form material
