This paper describes new gestures on the Multi-touch table. The 2 new gestures with 3 fingers are used for minimizing of all windows that is already open and converting Aero mode. We also implement a FTIR (Frustrated Total Internal Reflection) Multi-touch table that consists of sheet of acrylic, infrared LEDs, camera and rear projector. The operation of proposed gestures is verified on the implemented Multi-touch table.

A new design method is proposed for a fuzzy PD controller. By analyzing phase plane characteristics we can build and optimize the rule base of fuzzy logic controller. Also, a new gain tuning method is used to improve performance in the transient and steady state. The improved performance of the new methodology is shown by an application to the design of control system with a highly nonlinear actuator.

Although it is difficult to predict the future engineers, including optical engineers, must do it on a regular basis. After all, what is the generation of a new optical design, but an attempt to predict what will be needed next year\ulcorner But optical engineers do not consult oracles or look into crystal balls, instead they look at past history, new research, and the trends in technology. This talk will use this approach to look at where optics will take us in this new century. (omitted)

In this paper the authors proposed a new anisotropic yield criterion for porous ductile materials. By using the proposed yield criterion and its flow rules a damage evolution of anisotropic sheet under biaxial tensile loading is investigated. A comparison of yield locus and damage evolution between the proposed yield criterion and experiments are carried out. the results are in good agreement.

A simple estimate of Feynman path-integration with general potential via its new definition is given and found to be very useful. This new method will help find the value of some Feynman path-integrals as precise as one wants.

Some new explicit bounds on the solutions to a class of new nonlinear retarded Volterra-Fredholm type integral inequalities in two independent variables are established, which can be used as effective tools in the study of certain integral equations. Some examples of application are also indicated.

A new marine sponge in the family Microcionidae, Ophlitaspongia yongjeongensis n. sp. is collected from Yongjeong-ri, Hyeongyeong-myeon, Muan-gun, Korea during 2005-2007. O. yongjeongensis n. sp. is closely related to O. reticulata in growth form (shape and color). However, the thick style and slender style of O. yongjeongensis n. sp. are larger than O. reticulata's (Bergquist and Fromont, 1988).

Two new marine sponges in genus Suberites, S. hataedoensis n. sp and S. waedoensis n. sp have been collected from Hataedo Island and Waedo Island, Korea during 2005-2006. S. hataedoensis n. sp. is similar to S. durissimus in the spicule composition and texture. However, they differ in growth form, skeleton and surface. S. waedoensis n. sp. is similar to S. japonicus in spicule composition and skeleton. However, they differ in growth form, surface and texture.

Chelonaplysilla supjiensis n. sp. belonging to family Darwinellidae was collected from Jejudo Island, Korea in 2008. C. supjiensis n. sp. is closely to C. noevus in surface structure and skeleton, but differ in surface, sandy reticulation mixed with many spicule detritus. This study is a new record of genus, family and order in Korea.
