This paper presents an economic analysis for the travel aids service system for visually handicapped persons through RFID (Radio Frequency Identification). This research estimates both cost and economic effect of the service. By using input-output analysis technique, three kinds of repercussion effects - domestic production, value added, and workers induced by the travel aids service - are also calculated. To evaluate the profitability of the service, we investigate the procedures through which the service has an effect on the interested parties and develop formulas describing the procedures. The benefit of the service have been generally obtained by measuring the willingness to pay (WTP). This paper, however, obtains the monetary value of benefit by estimating the parameters of the formulas, so that a close improvement of the service may be possible with the result of the economic analysis.

In this paper, we discussed a methodology for education of German as a foreign language. In order to see how grammar and a function of communication should be linked, we investigated the way how grammar is dealt with in a chapter teaching “showing the way” as a communicational situation in 8 different highschool textbooks. To maximize the efficiency of teaching a specific grammar factor, we tried to establish which one should be linked to this communicational situation. Two conditions are necessary for this. Firstly, typical sentences for “showing the way” should be expressed by the grammar factor. Secondly, the grammar part associated with the expressions used for the communication situation should be more closely related to this one than any other communication situation. We concluded that the most efficient grammar factors that can be associated with the communication situation, “showing the way” are dative preposition and imperative, and that imperative can also be effectively associated with other communication situations such as “birthday and invitation”, and “health and treatment”.

The purpose of this study is to evaluate the effectiveness of the way-finding system on the facility management in the general hospitals. For this purpose, visiting survey and questionnaire study are carried out for four general hospitals. Based on the results, way-finding system such as sign board is a essential element for patient satisfaction as well as facility management.
