Abstract
The author, as an examiner, feels that the number of really "interesting" papers that deserve the prizes has been decreasing. Good papers should excite readers with at least one of the following features. First, novelty of the topic: unexpected problems or surprising conclusions are an important feature of interesting papers. Second, useful results: practical usefulness is an important rationale of research in our Society. Even analysis of a single case will be useful if any new aspects, models or methods introduced are applicable to other similar cases and thus extend our understanding. Third, logical coherence: this does not only concern the logical completeness per Se, though indispensable in the natural science. Studies of subjects covering natural, human and social sciences, which are of interest for us, require sound logic in modeling phenomena involving both physical and social aspects and applying the model to the real world. In fact, many papers fail in meaningful combination of logic and usefulness. The author expects more effort of both authors and examiners to improve the quality of papers appearing in our Journal.
