短跑道速滑起跑动作及肌电图分析

运用三台高速摄影机对三名优秀女子短道速度滑冰运动员起跑动作进行解析分析。研究表明：在起跑过程中股关节始终保持着外转位,在整个身体倾斜的状态下发挥着蹬冰力,臀中肌在这样的动作中起到了决定性的作用。在肌电图的解析中,利用足关节的屈曲动作既完成了移动身体重心又保持了身体前倾,在这样的状态下进行蹬冰的过程中,胫骨前肌起到了极其重要的作用。因此,对臀中肌及胫骨前肌,应采取积极的训练。     

The Usefulness of Saturated Salt Solution Embalming Method for Oral Surgical Skills Training: A New Cadaveric Training Model for Bone Harvesting

The purpose of this study was to assess the usefulness of saturated salt solution-embalmed cadavers for oral surgical skills training related to bone graft harvesting. Two half-day surgical skills training workshops were held at the Tokyo Medical University utilizing eight cadavers embalmed with the saturated salt solution. A total of 22 participants including oral surgeons, residents, and dentists attended the workshop. Surgical training consisted of six procedures related to intraoral and extraoral bone harvesting. The participants were surveyed to assess self-confidence levels for each surgical procedure before and after completion of each workshop. The Wilcoxon signed-rank test was used to compare the differences between each median score before and after the workshop. There were statistically significant increases in the self-assessed confidence scores in bone harvesting procedures for the zygomatic bone (P = 0.003), maxillary tuberosity (P = 0.002), and other sites (P < 0.001). The anatomical features of saturated salt solution-embalmed cadavers were also examined. The textures of the oral mucosa and skin were similar to those of living individuals. The structure of bone tissues was well-preserved and the hardness was realistic. Consequently, all procedures were performed with sufficient realism. The saturated salt solution method has a relatively low cost of preparation and storage, and almost no odor. The authors suggest that saturated salt solution-embalmed cadavers could provide a new model for oral surgical skills training in bone harvesting.     

教师发展(FD)的课题——日本的视角

本文以日本为例,系统研究了大学教师发展（FD）的背景、进展和课题。由于全球化、市场化以及知识化社会等背景,日本在80年代以后开始重视大学教师发展,推动FD制度化。教育质量保证是FD的基本原则。在21世纪,FD的理论和实践都有待于提高到新的阶段。这里不仅包括教师组织、课程、评价制度等要素的改善,还包括重新思考教学学术的问题。

A comparison of influence strategies utilized by managers in American and Japanese organizations

This study is a preliminary investigation of computer‐mediated communication (CMC) as a functional alternative to face‐to‐face communication. We examined the relationships between motives for using the Internet as a CMC channel and motives for face‐to‐face interactions as well as the influence of locus of control and communication apprehension as antecedents of face‐to‐face and mediated interactions. We surveyed a sample (N=132) of Internet users and tested the hypothesis that no differences exist between CMC and interpersonal communication motives (i.e., that they would be functional alternatives). We also used MANOVA and ANOVA procedures to see if main and interaction effects existed for high and low locus of control and high and low CMC apprehension respondents on interpersonal and media motives. Results indicated CMC Apprehension main effect differences for communication motives, and that use of the Internet as a communication channel is not perceived as a functional alternative to face‐to‐face communication.     

近代温州与台湾的航运关系

通过对海关报告、地方志、领事报告、新闻报道等史料的分析,探讨了台湾在清朝统治时期和日本占领时期与温州之间的航运和贸易情况.清代以来,温州利用帆船航海的便利,发展了与台湾的航运和贸易关系,其中以戎克船(清式中国帆船)为媒介的猪、米贸易在温-台贸易中占了相当大的比例.温州米产量不多,从米作丰富的台湾输入米谷以补充本地的不足.而台湾民众日常饮食结构中占有一定比例的猪肉则有较大一部分来自温州及附近地区.     

The competitive environment of academic productivity and the academic research enterprise in the case of Japan

This article deals with the various problems related to the given title from four sections. Section “Social function of the academic research enterprise (ARE)” focuses on three problems: Framework of the research on the ARE; Functions of the graduate school in the ARE; and Centers of learning and Japanese ARE. Section “Structure of ARE” discusses two problems: Structure of social stratification and the structure of ARE in the policy framework for the current ARE. Section “Social condition of ARE” argues over three problems: Social condition of the ARE; The effects of change of national policy on the ARE; and National government policy for the ARE in the postwar period. Section “The impacts of the national government policies on ARE” treats three problems: Trend of the recent national government policy on the ARE; Some unintended effects of the policies; and Discussion of proposals for reform. These discussions lead to concluding remarks.     

Construction of a Japanese Patent Database and a first look at Japanese patenting activities

A new comprehensive patent database based on patent applications filed with the Japanese Patent Office is described. We present the methodology for the construction of this database, the IIP Patent Database, its basic features and we discuss the recent history of patenting in Japan. We also compare citing-cited patterns of Japanese patents in this database with the citing-cited patterns for the same patents registered in the US, using OECD patent family information to identify US counterparts. We found similar patterns in the two countries, although citation is provided by patent examiners in Japan, while in the US a large share of citations is made by inventors.     

The role of corporate scientists in innovation

We conducted empirical analysis of the role of corporate scientists in Japanese pharmaceutical companies using data on published papers and patent applications. We found that scientists with the highest publication performance scores did not apply for a considerably greater number of patents than other researchers in their companies. Instead, we found that these “core scientists” had a positive effect on the number of patent applications filed by their co-authors. Our findings suggest that core scientists play an important role as central conduits for the in-flow of knowledge from outside their companies, thereby stimulating innovation.     

LQ preview state feedback with output regulation constraint

This paper addresses the output regulation problem for a class of preview control systems, and derives a state feedback law which suppresses the steady-state error caused by the excitation from polynomial or sinusoidal exogenous inputs. Recently, the output regulation condition for the broader class of distributed parameter systems is characterized via the operator regulator equation. We show that a solution of the operator regulator equation specialized to the preview control system is obtained by solving the matrix regulator equation, and provide the state feedback law which attenuates the transient error optimally with respect to an LQ (Linear Quadratic) performance index.
