Our research group have been conducting simulation studies for analyzing arrhythmia such as sick sinus syndrome, atrial fibrillation, ventricular tachycardia and fibrillation using multi-scale heart models with personal computer and supercomputer. One purpose of our simulation studies is to stratify the arrhythmic risk non-invasively using computer simulation. Recent study has shown that conduction delay around the right ventricular outflow tract is one of the mechanisms to induce ventricular arrhythmias such as Brugada syndrome. Our findings from computer simulation suggest that our model may be useful to stratify the arrhythmic risk in the Brugada syndrome. In this symposium, we will present our simulation scheme and recent progresses. In addition, we would like to discuss our future prospect and the possibility of computer simulation.

高齢者は,老化に伴い筋肉が減少しサルコペニアといわれる状態になりやすく,また種々の機能低下をきたしフレイルに陥りやすい。特に歯科領域では嚥下機能低下,味覚・嗅覚の低下,歯を含めた口腔機能低下などのために食事摂取量が減り,そのうえに他の疾患の合併なども加わり,栄養不良を示す患者が多い。また,逆に栄養不良は嚥下障害を含めた口腔機能の低下をきたすという悪循環に陥る(フレイルサイクル)。高齢者のフレイルでは認知症や転倒などの頻度が高くなり,寝たきりの原因になる可能性が高い。フレイルによる悪循環を断ち切るためにも歯科の役割は大きい。

Empathy is a multi-dimensional concept with emotional and cognitive components. The Interpersonal Reactivity Index (IRI) is a multi-dimensional scale of empathic traits. Although some researchers have attempted to translate the IRI into Japanese, these translated scales had limitations with content and construct validity, and measurement invariance. We therefore attempt to overcome these limitations by developing a new Japanese version of the IRI (IRI-J). We used three approaches to assess the validity and measurement invariance of the IRI-J. In Study 1, content validity was tested using back-translation, and construct validity was confirmed through a comprehensive investigation of a web-based survey using six other scales. Results indicate that the factor structure of the IRI-J was equivalent to that of the original version, and that the IRI-J had adequate reliability and construct validity. In Study 2, measurement invariance by gender was confirmed using data from four web-based surveys. These results suggest that the factor model of IRI-J for each gender is equivalent. The present study thus provides an improved measure of empathic traits for the Japanese population.

Sulfur-added vanadium pentoxide (S-V2O5) powder prepared using our method was applied to the cathode active material used in magnesium rechargeable batteries. The preparation of S-V2O5 from a sulfur and vanadium pentoxide mixture was done with low-temperature plasma generated using carbon felt and 2.45-GHz microwave (CF-MWP). The S-V2O5 structure was investigated using XRD, XPS, Raman spectroscopy, and DRS-FTIR. Results revealed that the S-V2O5 particle surface contains sulfur atoms and that its structure is amorphous, like xerogel, although the bulk preserved the same structure as that of V2O5 crystal. Charge-discharge tests for S-V2O5 showed exceedingly high specific capacity of 300 mAhg−1, which far surpasses that of V2O5 (160 mAhg−1). The cycle performance of S-V2O5 (300 mAhg−1 after 20 cycles) was also more stable than that of V2O5 (70 mAhg−1 after first cycle). Moreover, the discharge voltage and the specific capacity did not degrade under any discharge rate condition from C/2 to C/10.

Bust silhouette is one of several very important aesthetic points in the appeal of a women’s body, and it is also well known that an attractive silhouette is influenced by both inner and outer garments. Some odd protrusions can appear in outerwear because of the underlying brassiere, in particular, in spring-into-autumn apparel. As a result, many young Japanese women experience discomfort related to this silhouette. Thus we investigated the relationship between the brassiere and the bust silhouette in knit shirt. The experimental results are as follows: (1) unnatural protrusions result from four causes: the seam, the cup line, the trim lace, and the malformed top part of the brassiere, (2) seamless cup type brassiere makes a contribution to a beautiful bust silhouette, and (3) characteristics of the half-cup type brassiere which produces the worst bust silhouette in knit shirt are the total angle of cup top (BθU + BθL) ≤ 155°, the curved height of the under-cup line (BBL) ≤ 6 mm, and the compression recovery (RC) ≤ 50%.

This special issue focuses on research in the field of security and strategic culture in international relations.The first point in creating this issue is the concepts stated in the title and the need to address it. The approach of elucidating the nature of foreign policy decision-making process from the perspective of security and strategic culture hasn't yet been established in Japan. In particular there is a paucity of conceptual debate. Hence, the primary objective of compiling this special issue is to mark the beginning of research in this field in Japan.The second point is the historical timeline of security and strategic culture studies. Is it possible to explain the relationship between cultural studies and actual strategic diplomatic choices and behavior? It is evident from the existing research that this question is difficult to verify. However this does not mean that cultural studies in this field are not required. The importance of cultural approaches involving values and ideals has steadily increased in the Post Cold War era. While the cultural approach is not a necessary and sufficient condition for strategic diplomatic choices and behavior, its significance as necessary condition is undeniable. Despite that, there is hardly any full-fledged research in Japan in this field.Given the above context, this special issue is an attempt to shed light on the trends in research and interests in the field of security and strategic culture in Japan. A majority of the arguments in this issue are aimed at revealing diplomatic behavior that stems from history, culture and values. This can be thought of as a result of progress in the field of area studies. This issue contains examples from the United States, China, Eastern Europe and England. The next argument is a case study of strategic culture which looks into the influence strategic culture has on leaders. You find papers on Iran and England, mainly the Tony Blair dministration. The third argument focuses on the changes in values and world view among the citizens brought about by the changes in the global environment in the Post Cold War era. You find is some discussions of changes in Germany and France from a cultural and value perspective. Lastly this issue also features a paper characterized by a comparative study in attitudes towards intelligence in England and the United States and discussing the position of Japan within the above framework.

The most important safety problem concerning the LMFBR is related to core component damage caused by molten fuel coolant interaction. This problem has been reviewed under the items of out-of-pile test, in-pile test and analytical models. The elements of the physical geometry relevant to the out-of-pile test are shocktube, tank, jet injection, mixing and fuel pin. The major difficulty is to melt the large amount required of fuel (10kg). The in-pile test facilities operative today are TREAT, ETR, CABRI and HFR. Almost all the analytical models are based on the Cho-Wright model.

It is believed that the success of the goalkeeper (GK) in saving difficult shots by diving is a key factor in soccer because it can influence the outcome of the game to a large extent. However, the most appropriate way to exert force during the diving motion according to the course of the shot from either leg is still unclear. Therefore, the purpose of this study was to clarify the fundamental mechanism of a GK's diving motion according to the height and distance of the shot. We performed an experiment in which 11 university GKs participated. They were asked to dive toward balls set at 3 different heights located a short or a long distance from the GK. By examining the GKs' diving motions, we calculated the ground reaction force (GRF), joint angular velocity, and joint torque. The results indicated that the magnitude of the GRF under both legs and the direction of the GRF under the ball-side (BS) leg differed with the ball height. We also found that a higher dive by the GKs corresponded to a larger counter-movement of the contralateral-side (CS) leg and a higher stopping power of the BS leg in order to increase the vertical velocity, and more exertion of extension torques at the hip and foot for takeoff compared to those in lower dives. Furthermore, a lower dive of the GKs corresponded to a larger angular impulse of the BS hip adduction after the BS leg touched the ground. These findings suggest that during the takeoff part of the diving motion of a GK, depending on the ball height, the CS leg controls the magnitude of power and the BS leg controls both the magnitude and the direction of power in order for the GK to dive directly towards the ball.
