The purpose of this study was to examine within-subject differences in bat-swing trajectory between intentional hitting towards the same field and towards the opposite field. 19 industrial league baseball batters and 16 collegiate baseball batters performed same-field hitting (SH) and opposite-field hitting (OH). The movement of the bat during the swing was recorded with two high-speed cameras (1000 fps) for 3D analysis. At the instant of ball impact, the striking surface of the bat faced towards the same field in SH and towards the opposite field in OH. The bat-head trajectory immediately before impact was directed obliquely upward in SH, whereas it was directed obliquely downward in OH. Throughout the swing, the projection angle of the bat on the vertical plane was greater in OH than in SH, and the ratio of the translational component of the bat-head speed to the resultant bat-head speed was significantly greater in OH than in SH. These results suggest that the characteristics of the bat swing in OH provide a suitable impact condition to drive the ball towards the opposite field, as evidence has demonstrated that (1) a batted ball is likely to travel towards the opposite field when the lower half of the ball is hit by a vertically inclined bat, and (2) the striking surface of the bat is unlikely to turn to face towards the same field when the contribution to the resultant bat-head speed is generated more by the translational component of the bathead speed than by the rotational component.

Although a causal relationship has been suggested between Team Identification and Place Attachment, it may be necessary to verify the existence of the parameters between them. In this research, "The rise of Team Identification is accompanied by the rise in the evaluation of the social environment of the community, and leads to the rise of Place Attachment," was aimed at the hypothesis to be verified.    As a result of the two-way analysis of variance based on data from three longitudinal surveys, we determined that Team Identification ascending group significantly increased both Place Attachment and the bonds of the community as compared to the non-ascending group, and it was suggested that the evaluation of the social environment of the community rose in the ascending group. It can be said that the hypothesis was supported, considering the fact that "regional attachment influence structure" was confirmed in Imabari-City, the area of survey on this study.

性的嗜好により経肛門的異物挿入で直腸穿孔となった症例を経験した。症例1,64歳男性。以前よりホースを肛門に挿入する自慰行為を行っていた。受傷当日も,ホースを使用した自慰行為を施行していたが,行為後より腹痛を認め,経過観察するも症状悪化したため近医へ救急搬送された。近医で処置困難と診断され当院へ紹介となった。精査にて直腸穿孔を認め,ホースによる直腸穿孔と診断し,緊急開腹術を施行した。症例2,75歳男性。友人に肛門へソーセージを挿入された。その後,ソーセージの排泄は認めず,腹痛増悪したため近医を受診された。イレウスと診断され,当院紹介受診。精査にてソーセージによる直腸穿孔と診断し,緊急開腹術を施行した。性的行為による経肛門的直腸異物挿入での直腸穿孔はまれであるため若干の文献的考察を加え報告する。

Seen from the perspective of cultural interaction, Myōken was originally therepresentative deity of esoteric Buddhism; however, it is believed that under the infl uence of multiple gods, this deity underwent a change. For example, Zhenwu, as the god Zhenzhai Lingfu, blended and fused with Myōken. Because of this syncretism, a Zhenwu-type Myōken appears in fi gures, such as the Chiba Myōken. In other examples, however, Myōken assumes a form close to the Daishōgun, and a number of diverse images have been preserved. This diversity of the Myōken god suggests that it should beconsidered a composite of multiple gods.
