Shared reflection activities for fostering academic emotion and attitude skills in information studies
In this study, we sought to clarify how activities for learning the content of peers’ self-reflections and self-assessments affect the development of Japanese high-school students’ academic emotion and attitude skills during a unit of Information I , a required course that explores information technology To that end, we proposed a cycle of reflection sharing and evaluation and practiced it throughout the unit. Learners in the experimental group participated in reflection-sharing activities with peers and learners in the control group did not share their reflections with peers . Their responses to LMS delivered pre- and post-practice questionnaires were read by instructors from quantitative, qualitative, and affective perspectives A comparison of the results suggests that shared self-reflection activities can effectively increase learners’ awareness of connection s between their learning and their lives, their interests, and their own improvements and transformations

FACTOR ANALYSIS OF SPRINT PHASES ON THE SPEED CURVE OF THE 100M DASH
Previous studies have indicated that the speed curve of the 100m dash consists of some distinct phases which can be used to analyze an athlete's performance. The purpose of this study was to introduce a method using a portable computer as a device for the measurement of sprint time and the illustration of the speed curve, and to clarify a simple model of sprint phases on the factor structure. Based on the data of 133 participants, principal factor solution was given to the correlation matrix, and varimax rotation was applied to simplify the factorial structure of sprint phases. Finally, two factors were extracted and interpreted. It is suggested that this method is useful for measurement and evaluation in the 100m dash, and that a simple model of sprint phases may be explained by these two factors. These findings are important in predicting the ability of 100m sprinters and in considering coaching methods in terms of technique, training, strategy, etc

Preparation and Characterization of Nitridation Layer on 4H SiC (0001) Surface by Direct Plasma Nitridation
A nitride layer was formed on a SiC surface by plasma nitridation using pure nitrogen as the reaction gas at the temperature from 800°C to 1400°C. The surface was characterized by XPS. The XPS measurement showed that an oxinitride layer was formed on the SiC surface by the plasma nitridation. The high process temperature seemed to be effective to activate the niridation reaction. A SiO2 film was deposited on the nitridation layer to form SiO2/nitride/SiC structure. The interface state density of the SiO2/nitride/SiC structure was lower than that of the SiO2/SiC structure. This suggested that the nitridation was effective to improve the interface property.ArticleMaterials Science Forum, Vols. 778-780, pp. 631-634 (2014)journal articl
Plasma Nitridation of 4H-SiC by Glow Discharge of N2/H2 Mixed Gases
The mixed gas of nitrogen and hydrogen was used for the plasma nitridation of SiC surface.A small amount of hydrogen was effective to activate the nitridation reaction and suppress the oxidationreaction. The interface properties were improved by using nitride layer as an interfacial bufferlayer of SiC MIS structure.ArticleMaterials Science Forum, Vols. 821-823, pp. 504-507 (2015)journal articl
