The purpose of this paper is to set forth an analytical method for determining and discovering a user's behavioral characteristics within an electronic mail environment based on a genetic algorithm. This analysis method consists of the following: a behavioral simulation which simulates individual use within a particular electronic mail environment model, and a process which evaluates user-behavior and selects suitable behavioral characteristics based on the simulation results. By repeating both the behavioral simulation and selection process of behavioral characteristics, we are thus able to compile a distribution-pattern of characteristic suitable to optimal 'initial stated' of particular electronic mail environments. The following two implications emerged from simulations: this analysis method can discover a distribution of user characteristics corresponding to the condition or 'initial state' of the environment is fixed, behavioral characteristics of users exhibited wide variance. Thus, as a result, this analytical method can be seen as a more accurate way to determine both the 'cost to' and ' effectiveness of' a given system for users as a materialization factor within an electronic mail environment. Finally, this method can also suggest management criteria for effective electronic mail environments.

This paper shows an empirical research of information systems between local government and private companies. Because we compare the two organizations with each having different purposes, as a research framework we used the ElS(Excellent Information System) model which has been built upon case studies of private companies. The EIS model presents the information systems in four types customer / resident satisfaction, business process improvement & re-engineering, enterprise transformation, and symbiosis with society & environment, respectively. Each of the organizational information systems introduced here belongs to one of these types. To exemplify or verify of the EIS model, we conducted a survey research at local government and private companies. The data from the questionnaire are analyzed, by factor analysis. In this analysis, we discovered four factors at work in both the public and private sectors. And the factors from both sectors are interpreted in the same perception level, but the reference structure differs from each other. We investigated the qualitative differences between the information system of the local government and private companies from these structural differences.

In today's environment, the rate at which individuals and, organizations learn may be the only sustainable competitive advantage. The challenge, then, is to discover new management tools and methods to accelerate organizational learning. In this paper, (1) the author clarifies the theoretical meaning of the learning organization using his new double-loop learning model, and (2) claims that simulation can prove to be a powerful tool to create a learning organization through facilitating systems thinking. Simulation can overcome the dilemma of learning from experience and the difficulties of creating shared mental models, and facilitate organizational learning.

In view of the characteristics of contemporary conceptual data modeling and of the limitations of the conventional form design method, this paper proposes a 'conceptual form' model as a new model for the basis of the form design theory. This model possesses an algebraic architecture which analyses database access paths, data presentation structures, and effective form structures.

It is very important for the decision making in the management, management consulting and etc. to evaluate a corporation from a long-term point of view, and to present strategic plans concerned with the product-market strategy. However, corporation evaluation systems which have been developed can not analyze qualitative factors enough which have great influence upon the future of corporations, and can not present above strategic plans. Therefore, we developed a prototype of corporation evaluation support system which presents strategic plans. In this study, corporations are evaluated from a point of view of both quantitative and qualitative factors, and furthermore from a macro point of view, for example corporation life cycles and etc. Our system can effectively support users' decision making using many kinds of graphical user-interface and a distributed and cooperative processing.
