A study of peripheral text volume and sentence readability

Bulletin of the Faculty of Education, Yamaguchi University Volume 72

注視点の周辺文字量が文の理解度と読書速度に与える影響について検討した。視力をもとに実験参加者を２つの群に分けたところ、理解度テストの得点において、低視力者に比べ高視力者の得点が高くなった一方、読書速度においては視力による差が見られなかった。高視力者は理解度を高めるために読書速度を落としていた、あるいは、低視力者は読書速度を上げる代わりに理解度を低下させていたことが考えられる。また、読書量をもとに実験参加者を２つの群に分けたところ、画面に３～４行ずつ提示した文章では、読書量が少ない者は多い者に比べ、主観的な理解度を高く回答した。読書量が多い者はどの提示形態も同程度文字を捉えることができた。一方、読書量が少ない者は、画面全体に全文提示している文章では文字を的確に捉えることが難しいため、空白によって集中して文を読むことができた文章をより理解できたように感じたことが考えられる。

Effect of jump rope training on the Stretch-Shortening cycle ability in university track and field athletes and untrained students

Bulletin of the Faculty of Education, Yamaguchi University Volume 72

大学陸上競技選手と一般学生を対象として、多回旋跳びを段階的に増やした４週間の縄跳びトレーニングが伸張－短縮サイクル（SSC）運動遂行能力と走跳能力に及ぼす影響を検討した。陸上選手は通常のトレーニングのみ行わせる群と、それに加えて縄跳びトレーニングを行わせる群に分けた。縄跳びはできる限り短い接地時間で行わせた。縄跳びトレーニングによって、陸上選手では最大連続跳躍（RJ）の跳躍高/接地時間の値（RJ-index値）および走跳種目の記録に変化はなかったが、同じ縄跳びトレーニングを行わせた一般学生ではRJ-index値と立ち幅跳びの記録が向上した。個人値を用いた検討の結果、90回/分の１回旋跳びでは２回旋跳びに比べて接地時間は長い傾向があったが跳躍高は高く、RJ-index値は同程度であった。縄跳びトレーニングによって陸上選手では効果はないが、一般学生のSSC運動遂行能力は向上する可能性があること、また、リズムが約90回/分の短い接地時間での１回旋跳びは多回旋跳びとともにSSC運動遂行能力を高めるトレーニング手段となる可能性が示唆された。

Machine learning algorithm in J-BMS RC version and its effectiveness

Memoirs of the faculty of engineering, Yamaguchi university Volume 73 Issue 1

The Japanese Bridge Management System (J-BMS) RC version consists of the following three subsystems: (1) a bridge maintenance database system (J-BMS DB), (2) a concrete bridge rating expert system (RC-BREX) and (3) a maintenance plan optimization system (MPOS). Especially, in this paper, the RC-BREX system for deteriorating concrete bridges is described based on how to construct from a hierarchical neural network in order to carry out fuzzy inference and machine learning by using the neural network with the back-propagation method. Furthermore, the comparisons between diagnostic results by bridge experts and those of the proposed system are presented so as to demonstrate the validity of the system’s learning capability by using the training set for machine learning which obtained from inspection on actual in-service bridges and questionnaire surveys by bridge experts.

Independence and transparency of Taiwan’s nuclear regulatory bodies

Yamaguchi journal of economics, business administrations & laws Volume 71 Issue 1-2

Taiwan has not yet been singed the “Convention on Nuclear Safety; CNS” that was adopted by the International Atomic Energy Agency （IAEA） in 1994. However, if these international activities help promote nuclear safety, Taiwan must participate in it and fulfill its related obligations. Therefore, despite Taiwan being a non-member state to the CNS, it is required by the Convention to act as a member state to meet all the requirements addressed in the CNS. Ensuring the public trust of nuclear safety regulations in the most important policy issue for the location, operation, waste disposal and off-commissioning of nuclear power plants, etc. As part of an international comparison of nuclear safety regulatory bodies in the East Asian region, this note organizes and evaluates the independence and transparency of Taiwan’s regulatory bodies.

A macroeconomic model in which the bank determine the loan interest rate and the deposit interest rate

Yamaguchi journal of economics, business administrations & laws Volume 71 Issue 1-2

The purpose of this paper is to present a macroeconomic model, in which the bank determine the loan interest rate and the deposit interest rate by assuming the loan demand curve and the deposit supply curve. The bank adjusts the loan interest rate and the deposit interest rate while observing the difference between the assumed demand for loan and the actual demand for loan.
