Hakone volcano is situated at the northern tip of the Izu-Mariana volcanic arc in eastern Japan, and area that is both tectonically and volcanically active. Fumarolic activity is observed a.t post-caldera cone volcanoes within the caldera, and the northern extension of the Kita-Izu fault, the source of a M7.3 earthquake in 1930 (Kita-Izu earthquake), traverses the southern part of the caldera. Although there is no historical record of eruptive activity, many intense earthquake swarms have been reported since 1786 within the caldera. In this study, literature on earthquake swarms in 1917, 1920, 1933-35, 1943, 1944, 1953, 1959-60 are re-examined to reveal detailed development of the activity, seismic intensity and the epicentral region of these events. Two epicentral regions are recognized; the central cones region (1), and the southern part of the caldera (2). Earthquake swarms in (1) are often accompanied by rumblings and the main shock is not distinct; successive earthquakes are felt almost continuously during the peak of activity. On the other hand, earthquake swarms in (2) are rarely accompanied by rumblings and have obvious sequence of foreshocks, a mainshock and aftershocks. The largest earthquakes in the swarms in (2) are larger than those in (1). The two epicentral regions are both on the northern extension of the Kita-Izu fault system. Differences in the style of earthquake swarm activity in regions (1) and (2) may be due to differences of the geology and the source depth. Correspondence between fumarolic activity in the solfataras at central cone volcanoes and seismic activity was not observed except for the 1933-35 swarm. Most of the earthquake swarms at Hakone volcano are therefore probably tectonic earthquakes on the Kita-Izu fault system rather than being related to hydrothermal or magmatic activity within the caldera. Earthquake swarms at Hakone appear to have been rare before 1917, and except for 1786, no historical records exist even though one of the most important highways in Japanese history passed across the volcano. An interpretation that attributes the earthquake swarms since 1917 to foreshocks and aftershocks of the 1930 Kita-Izu earthquake would broadly explain the frequency of earthquake swarms at Hakone volcano since the early twentieth century.

近年、サービス指向アーキテクチャ(SOA)が、新しいソフトウェアアーキテクチャとして注目されているが、SOAに基づいたサービスおよびビジネスモデル設計に関する方法論はいまだ確立されているとは言い難い。本稿では、SOAアプリケーション設計のためのUML拡張およびその適用プロセスを提案し、実例とともに、現状の課題を提示する。Service-Oriented Architecture (SOA) is emerging in the area of software architecture. This paper provides a concept of development process, reference architecture and a new UML profile for SOA systems development and integration. The proposed development process allows system architect to cooperate with business analysts by leveraging the UML. SOA profile allows developer to model SOA system including interactions of services and business process that orchestrates services. This paper demonstrates how to use the proposed profile, and discusses issues remaining in the area of SOA.

Sports business attracts customers by players`skill, speed, and the favorite teams `victory.But in BC League, customers have been attractedby the relationships built between BCLeague and customers, and the relationshipsexpand the circle of customers.In this paper, the relationships built with customersin BC League would be promoted by"Shikake" and "Ba no Settei".And finally, the Author is proposing that"Shikake" and "Ba no Settei" would be necessaryin order to breed the strong relationshipswith customers and also breed Customer Ownership.("Shikake" which means a device topromote the relationships, and "Ba no Settei"which means the setting of the opportunityand the place to promote the relationships.)

Many disadvantaged youth in the United States are suffering not only from an academic achievement gap, but also from a profound civic empowerment gap- a widespread marginalization of those youth from civic engagement. Those who are in the low socioeconomic status are much less likely to be civically or politically engaged. The purpose of this study is to explore the significance and possibility of school-based citizenship education to empower youth in poverty and to overcome the civic empowerment gap. Specifically, a case of an urban school which has implemented Public Achievement is investigated. Public Achievement is a grass-roots, project-based citizenship education program, in which teams of young people discuss and solve problems in schools, neighborhoods, or broader communities. Poor neighborhoods tend to shape a hidden curriculum that instills powerlessness in youth and keeps them away from civic engagement. Schools, on the one hand, may reproduce and reinforce the disempowering hidden curriculum in the surrounding community; by not providing adequate civic learning opportunities, schools would send a message to students that they are not expected as productive citizens. On the other hand, the case in this study also suggests the strong possibility of school-based citizenship education; by providing an authentic civic learning opportunity like Public Achievement, schools may be able to empower students, teachers and community members by showing "the world they have never seen", and thus transform the hidden curriculum. Since most poor neighborhoods have many obstacles and very few resources to combat civic empowerment gap, it is significant that schools in such neighborhoods actively promote school-based citizenship education.
