Recent Development of Information Technology in Japanese Banks

2005-04Although Japanese banks have suffered from huge non-performing loans since the burst of the bubble, they have invested as much as possible in information technology. However, due to the shortage of available funds, each bank has felt that its investment was not high enough to compete with leading U.S. and European banks. This is one important reason why major Japanese banks have been merging with each other in recent years. Information technology has now become a key issue in the Japanese banking business. This chapter discusses the recent development of information technology in Japanese banks in detail. The section titled THE CHANGE IN THE BUSINESS MODEL provides a brief explanation of the current Japanese banking environment. In THE STEADY PROGRESS OF NEW INFORMATION TECHNOLOGY IN FINANCIAL INSTITUTIONS, we discuss how Japanese financial institutions, mainly banks, have dealt with new information technology. The section on INTERNET BANKING provides a detailed discussion of new Internet banks and the Internet banking services of existing banks. As information investment has an external effect, the market will fail without government assistance. Therefore, in GOVERNMENT EFFORTS: E-JAPAN STRATEGY, we explain what the Japanese government has done in terms of IT usage in financial services. Finally, the CONCLUSION section concludes this chapter.departmental bulletin pape

Convection by small temperature difference in a rotating cylindrical vessel

鉛直方向の中心軸周りに回転する円筒容器の中に現れる水平方向温度差が小さい場合の液体の流れを調べた．これまでに，同心円状の2つの円筒を用いたいくつかの実験的検討が行われてきた．今回の実験では，円筒容器とその外側の両方に水が入っており，円筒容器内の水は側壁から加熱または冷却される．アクリル製の円筒容器は半径97mm で，水面には取り外し可能な蓋を設置する．流れの可視化には，アルミ粉懸濁法を用いた．その結果，現れる流動パターンと傾圧不安定波は，テイラー数と熱ロスビー数の関係から，波数に関する共通点があるが，「ドリフト」や「ヴァシレーション」がないこと，波数が3以上の流動パターンの形態などの違いがある．We investigated the flow of the liquid that appears in a cylindrical vessel rotating about its vertical center axis with small horizontal temperature gradient. Several experimental investigations using two concentric cylinders have been carried out. In the present experiment, water fills both cylindrical vessel and its outside. Water in the cylindrical vessel is heated or chilled from the sidewall. The cylindrical vessel made of acryl is with a radius of 97 mm, and has a removable lid on water surface. We visualized the flow by the aluminum-powder suspension method. It was found that the flow patterns and the baroclinic waves have common points concerning wave number on the basis of the relationship of Taylor number and thermal Rossby number. There are some differences such as the absents of 'drift' and 'vacillation' and wave patterns with wave numbers more than 3.application/pdfdepartmental bulletin pape

Empirical cumulative distribution of birth year for patients with H1N1 (blue) and H3N2 (red), from the NCBI dataset, in the United States, between 1995 and 2008.

<p>The significant statistical dissimilarity between the distribution for the year of birth (P(MW) = 2.04E-24 and P(KS) = 1.13E-35) hints to an existing immunity against one of the subtypes in different age groups, possibly carried over from a previous pandemic.</p

Empirical cumulative distribution of ages for patients with H1N1 (blue) and H3N2 (red), from the NCBI dataset in United States and Oceania combined, between 2000 and 2007.

<p>The low probabilities computed via Mann-Whitney (P(MN)) and Kolmogorov-Smirnov (P(KS)) further confirm the results shown in <a href="http://www.plosone.org/article/info:doi/10.1371/journal.pone.0006832#pone-0006832-g002" target="_blank">Fig. 2</a>.</p

Empirical cumulative distribution of ages for patients with H1N1 (blue) and H3N2 (red), from the NCBI dataset, in the United States, between 1995 and 2008 (left) and Oceania, between 2000 and 2007 (right).

<p>Complementary to the results from New York State (<a href="http://www.plosone.org/article/info:doi/10.1371/journal.pone.0006832#pone-0006832-g001" target="_blank">Fig. 1</a>), the low probabilities computed via Mann-Whitney (P(MN)) and Kolmogorov-Smirnov (P(KS)) tests show a significant difference between the distributions, which is spatially and temporally consistent.</p

The studied datasets from New York State and the NCBI.

<p>a: the median age.</p><p>b: the birth year of the oldest person.</p><p>c: number of counts.</p>*<p>Probabilities computed for Mann-Whitney (P(MN)) and Kolmogorov-Smirnov (P(KS)) tests.</p

Empirical cumulative distribution of ages for patients with H1N1 (blue) and H3N2 (red), from the NCBI dataset, in United States during the influenza seasons of 2006–2007 (left) and 2007–2008 (right).

<p>The significantly low probabilities computed via Mann-Whitney (P(MN)) and Kolmogorov-Smirnov (P(KS)) tests during separate influenza seasons show the consistency in our results among sub-portions of the data and refute the possibility that the previous statistical results are due to a unique season.</p
