This paper tries to explain how the Japanese postwar export promotion system worked and what kind of roles JETRO played in this system. Two case studies of JETRO's successful export promotion activities were also introduced. The paper also points out the themes to be solved by the TPO (Trade Promotion Organizations). Finally the paper shows four advices for Latin American Export Promotion Agencies, based upon JETRO's postwar experiences.

This paper describes a knowledge model for a configuration problem in the do-main of traffic control. The goal of this model is to help traffic engineers in the dynamic selection of a set of messages to be presented to drivers on variable message signals. This selection is done in a real-time context using data recorded by traffic detectors on motorways. The system follows an advanced knowledge-based solution that implements two abstract problem solving methods according to a model-based approach recently proposed in the knowledge engineering field. Finally, the paper presents a discussion about the advantages and drawbacks found for this problem as a consequence of the applied knowledge modeling ap-proach.

The broadcast service spreads a message m among all processes of the system, such that each process eventually delivers m. A basic broadcast service does not impose any delivery guarantee in a system with failures. Fault-tolerant broadcast is a fundamental problem in distributed systems that adds certainty in the delivery of messages when crashes can happen in the system. Traditionally, the fault-tolerant broadcast service has been studied in classical distributed systems when each process has a unique identity (eponymous system). In this paper we study the fault-tolerant broadcast service in anonymous systems, that is, in systems where all processes are indistinguishable.
