Involutions of compact Riemannian 4-symmetric spaces
Let G/H be a compact 4-symmetric space of inner type such that the dimension
of the center Z(H) of H is at most one. In this paper we shall classify
involutions of G preserving H for the case where dim Z(H)=0, or H is a
centralizer of a toral subgroup of G.Comment: 39page
Detection of Hotspot for Korea Earthquake Data using Echelon Analysis and Seismic Wave Energy
Echelon analysis (Myers et al., 1997) is a method to investigate the phase-structure of spatial data systematically and objectively. This method is also useful to prospect the areas of interest in regional monitoring of a surface variable. The spatial scan statistic (Kulldorff, 1997) is a method of detection and inference for the zones of significantly high or low rates based on the likelihood ratio. These zones are called hotspots. The purpose of this paper is to detect the hotspot area for spatial data using echelon. We perform echelon analysis for Korea earthquake data. We use ESRI’s ArcGIS that is geographical
information system (GIS) software to make the meshed areas and get contiguity information of these areas. With this contiguity information on the meshed areas, we detect the hotspot area using echelon analysis and spatial scan statistics. In addition, we compare with the result of analysis based on the total of number of times simply and the seismic wave energy
A Survey Study of University Students’ Awareness on Social Contribution and Regional Cooperation
Recently, competition among universities has a whole new face, and emphasis is given toward interdependence and
interactive evolution between universities and regions. From this social perspective, universities should contribute to
regional development by serving the regional society using results of intellectual work, and it is necessary for
universities to accomplish social contribution and regional cooperation strategically. One of the most important parts in
strategic planning is that students participate in activities for social contribution and regional cooperation. This paper
presents a survey of the university students’ awareness on social contribution and regional cooperation using several
statistical methods and attempts to find factors which affect activities for social contribution and regional cooperation
using logistic regression analysis
Survey Study of Resident Awareness on Waste Final Disposal Site
As construction of final waste disposal site is essential recently, a problem where we should build it becomes important issue. However, public opposition occurs for the construction because the final waste disposal site has negative image such as pollution of various kinds, increase of traffic volume and noise by truck and bulldozer, and aggravation of living conditions. Public opposition is the most critical problem in constructing final waste disposal site. The source of public opposition has been characterized as NIMBY or not-in-my-yard. This paper presents a survey of the resident awareness on final waste disposal site, and attempts to find factors which affect the public opposition using logistic regression analysis and CART(classification and regression tree)

A feasibility study of the measurement of Higgs pair creation at a Photon Linear Collider
We studied the feasibility of the measurement of Higgs pair creation at a
Photon Linear Collider (PLC). From the sensitivity to the anomalous
self-coupling of the Higgs boson, the optimum collision energy
was found to be around 270 GeV for a Higgs mass of 120 GeV/. We found that
large backgrounds such as and
, can be suppressed if correct assignment of tracks to parent
partons is achieved and Higgs pair events can be observed with a statistical
significance of by operating the PLC for 5 years.Comment: 7 pages, 8 figures, 5 table
