The purpose of this study was to examine how the length of saccadic reaction times (SRTs) affect the timing error of coincident responses. Three male subjects each participated in four kinds of tasks consisting of eight blocks of 30 trials. In the beginning, the subjects kept gazing at a fixation point on the right side of a computer monitor. When a target began to move horizontally from a starting point (near or on the fixation point) to left at a constant velocity, they made a saccadic eye movement to pursuit it as quickly and accurately as possible. After then, they pressed a push button at the moment they supposed that the target just arrived at a given point through a masking zone making it invisible. Four visual stimulus patterns consisted of two fuzzy vision conditions and two clear vision conditions. Fuzzy vision strategies make low state of focused visual attention by separating a viewpoint, from a visual target, with making it blurry and/or double imaged, and have possibility to evoke the express saccade easily. The repeated-measured two way ANOVA was employed to analyze SRTs and the absolute and constant errors of anticipated responses to the four tasks. As a result, the fuzzy vision task showed saccades with extremely short reaction times, small absolute errors, and stable constant errors close to zero. Such a fuzzy vision strategy, in contrast with a clear vision strategy, would improve motor performance in high-speed ball games.

The world economy has entered the Globalization Age by expansion of international trade and innovative changes of transportation technology. In this situation, strategic alliance has been spreading as an important business strategy for survival. In this paper, by classifying in complementary position, assets and finance, regionality. mutual reliability, purpose identity for the selection of the partner, it was studied. Through strategic alliance, shipping companies do not need the additional capital to increase thephysical assets such as vessel capacity. The purpose of alliance can be summarized as follows : broadening of service area, cost reduction through vessel sharing, realization of rationalized shipping service by terminal and equipment or facilities sharing. Strategic alliances are generally more formal agreements than consortia and impose long term and far reaching obligations on their members. Each alliance group concentrates on not only increase of slot capacity in the trunk routes but also the development of the feeder routes one around the newly rising region. For the successful alliance, each shipping company should have its unique and complementary competitiveness as a core competence.
