| <Abstract>
For better evaluation of hazardous area affected by the slope failures as well as landslides, the web-based Slope Stability Evaluation model (SSE-web) has been constructed. In the SSE-web, the relationship between the gpast slope failuresh and the gcausal factors (i.e., satellite remote sensing data, geographical information)h are constructed. The SSE-web consists of the following systems; i) Pre-processing system, ii)Analysis system, iii)Post-processing system, and iv)Information providing and management system. The functions for making the causal factors belong to the pre-processing system. Through the analysis system, the factor analysis could be carried out on the slope stability evaluation. The post-processing system supports the editorial works on the slope stability evaluation maps as well as the analysis results. Furthermore, the post-processing system assumes a role to provide and manage those data sets. The system designs on the SSE-web might be a good guide for constructing the related system of spatial-data integration and analysis under the internet-environment.

| <Abstract>
A service for providing spatial information is recently increasing. This service is easily
used by a personal computer or a mobile phone. It is important that a digital map has a lot of
attributes on the spatial service. However, making attributes of digital maps requires a great deal of
time and money. Therefore, it is difficult to define attributes of spatial data and to produce these values.
The purpose of this research is to develop a system that can automatically produce and update attributes
of the digital map by searching on Web pages. Moreover, a function for searching spatial information
with a keyword of natural language is implemented.

In this paper, a Pavement Management Accounting System application (in brief, PMAS application) is
presented to control the life cycle costs of road pavement. The aim of the PMAS application is to provide the decision
makers with the planning information regarding repair strategies and the accounting information on the asset values
for the efficient asset management of road pavement. By comparing alternative accounting schemes, the authors
conclude that the maintenance accounting is the best accounting scheme for the efficient asset management of road
pavement. The PMAS for the asset management is constructed by applying the maintenance accounting scheme. The
validity of the PMAS presented in this paper is investigated through case studies conducted for Mie Prefecture in
Japan.

| <Abstract>
Recently, CALS/EC is rapidly being promoted with the development of information
technology. CALS/EC aims at an increase in efficiency of business by carrying out information
exchange, cooperation, sharing, and reuse for digital results in the process of the life cycle of
investigation, planning, design, construction, and maintenance management in public works. In
CALS/EC, attention is being focused on utilization of 3D information for CAD or GIS. In order to
promote CALS/EC in the future, it is very important to utilize 3D information. The purpose of this
present research is to undertake reference investigation about practical utilization of 3D information in
the construction industry. Moreover, the present condition of practical utilization of 3D information in
the construction industry was analyzed.

| <Abstract>
The objective of this study is to propose a new method to simulate the granular flow with
Cellular Automata (CA). First, it is demonstrated through the preparatory numerical experiment that
Moorefs neighborhood is reasonable as a basic rule to realize the effect of gravity. However, the rule in
which only the effect of gravity is taken into consideration is not satisfactory. Then, the effect of
friction between the grains and between the grain and wall is combined into the rule. Rice grains are
used in the experiment of granular flow. The results of experiment of granular flow are compared with
the simulation by the method proposed in this study.

Collaborative and intelligent construction means production system that rationalizes
construction by applying information technology to utilize a great variety of information. This paper
presents pre-survey, framework of representation being possible to utilize data, general framework of processing data
and managing information to assess construction profile, and development of prototype of construction information
management system, which are included in study on framework of construction profile to support the collaborative
and intelligent construction system.
