Document Management and Tracking System for Emergency Response Headquarters

One problem faced by an emergency response headquarters is that emergency response procedures are not adequately documented. This lack of documentation is a major problem in testing preparedness for future emergencies. However, it is difficult to document an emergency response while actually responding to an event. The authors have attempted to resolve this issue by building a content management system with a focus on documentation created during emergency responses and on documentation that can be printed out and attached.

A proposal of P2P content retrieval system using access-based grouping technique

In recent years, the diversification and ubiquitousness of information is rapidly advancing due to the development of the information and communication technology. As for the usage of the information, the attention of sharing of information using P2P network rises, and it is becoming to be used in many fields. The distributed hash table (DHT) is one of the typical overlay networks on P2P. However, there is a problem of lacking of flexibility in the retrieval on DHT. In this paper, to improve the convenience of the content access, we propose an efficient content access method based on the grouping technique of the contents using the content access history and frequency and the evaluation of grouping efficiency (precision, recall) is performed by the simple simulation.

Program Learning Using Static Information and Dynamic Program Execution Slices

Nowadays, we can easily obtain a copy of practically any used program in our open source community for learning. However, the reality is that the level of such practically used programs is often complex and of such a large scale so that it is not as easy to understand them as one might expect. We believe that we do need some kind of environment to help the learner read and understand programs. Learning programs is necessary for other reasons such as program maintenance, reuse of programs. In this research, we built a model to use for program understanding. Using it, we examined possible ways of supporting program learning. Based on that, the objective of this paper is to present our efforts at developing a program learning environment, which helps narrow down the scope of a program to facilitate reading and understanding it while finding the differences of such dynamic information, as found in the program execution history, and also provide an environment in which the learner can use static information. We evaluate the efficiency of the proposed program learning environment through experiments.
