At university, except seminars and practicum, it is traditional for professors to lecture to students in a large hall. Such lectures make it difficult to foster student intellectual independence and cooperation. This is one reason why graduates can’t quickly adapt to company practices. To improve this situation, the authors introduced group learning in information management courses. New data in the field of information management increased the difficulty of adaptation to the change. A group of 3 to 5 learners made a presentation for the subjects of each week’s lecture. For this, students collected, analyzed and discussed the latest data. Furthermore, students were responsible for presenting questions from the class with answers. For a lecture targeted at more than 100 students, having students experience a form of information management by devising their own plan and creating work teams seemed to offer real educational benefits. This paper discusses the effectiveness and problems of this method with our experiments.

It is proposed to apply the “City Planning” concept for reconstructing complicated enterprise systems. However, considering current IT environment of utilizing commercial software packages, it is effective to start with designing an integrated infrastructure framework as the first phase of City Planning. This paper aims at proposing “EII Meta-model” as the integration framework that can optimize the overall enterprise systems from the City Planning point of view after examining the requirements of information infrastructure of e-business systems.

EII Meta-model consists of “Integrated Information Infrastrucfure Map”, “Service Framework” and “IT Scenario”. The Integrated Information Infrastructure Map is the structured scheme which combines the processes to select and decide applicable IT and to deploy them with maintaining and operating functions of the information systems. The Service framework is a set of procedures to decide and evaluate the service-level. And the IT scenario is a migration scenario that the Integrated Information Infrastructure Map can follow the change of business and IT environment.

Finally, we illustrate the case of information system for an online securities company, which is characterized by rapid change of business environment and applicable technologies, and demonstrate applicability and effectiveness of EII Meta-model.

This paper discusses the differentiation factors among the players in the B2C Internet businesses.

In the field of Behavioral Decision Theory in Accounting, many researchers have debated issue of sequential information processing by accounting professionals. Some researches insist that the results of previous studies are inconsistent. This paper presents two re-interpretations to these studies by considering the causes of inconsistency. From this consideration, it appears that the results of previous studies are theoretically consistent. Further, the examination in this paper raises a new problem about the method of previous studies. It is pointed out that two factors 1) ceiling effects and 2) levels of confidence cause the problem. In addition, the necessity of verifying about two proposed factors is insisted.
