This study is focused on the skill to prevent RIB (Rigid Inflatable Boat) from sinking. For better ability to prevent sinking, single hypalon tube is replaced by double TPU (Thermoplastic Polyurethane) tube that is excellent at frictional wear strength and oil-resisting qualities. High buoyant materials are arranged in empty spaces of ship so that ship's spare buoyancy is increased. And for restoration of stable position of ship, the self-righting system is installed. Aluminium alloy is used for increasing hull strength.

In general, gestures can be utilized in human-computer interaction area. Even though the acceleration information is most widely used for the detection of user’s intention, it is hard to use the information under the condition of zero or small variations of gesture velocity due to the inherent characteristics of the accelerometer. In this paper, a natural interaction method which does not require excessive gesture acceleration will be described. Taking advantages of the gravity, the system can generate various types of signals. Also, many problems such as initialization and draft error can be solved using restorative uprighting force of the system.

This is an quasi experimental study using nonequivalent pre-test post-test control design for the development of the CAI program and an analysis of its effects, for nursing college students to learn emergency patient triage. This program was developed from November, 2000 to middle of September, 2001 with the aid of curriculum design experts. The subjects of this study were 86 randomly sampled freshmen students of C nursing college in Ulsan. They were divided into 45 for the test group and 41 for the control group. The CAI program for the learning of the emergency patient triage has been developed on the basis of Merrill's Component display theory and Keller's ARCS theory and through the curriculum design process of Hannafin ＆ Peck. It has also been done with the use of Tool book 8.0, the multimedia righting tool. The experiment to verify the effect of the CAI program has been carried on from September, 20 to October, 8 2001. There were six hypotheses to accomplish the purpose of the study, and the analysis of the data was done with the use of SPSS/win program. As a result of this study, the author concluded that this CAI program is an effective mediation method to promote the learning accomplishment and learning motive for nursing college students. Therefore in the field of emergency nursing education, it would be possible to use this program as means for widening the possibility of self-learning and to promote individual learning of nursing college students.
