  • '테크노 골리앗'이라고 불리는 최홍만이 이종격투기 선수로 전향한 것을 계기로 현실세계에서는 이제야 하나의 문화상품으로 자리잡고 있는 이종격투기가 게임 계에서는 오래전부터 인기잘르로 각광받고 있다. 오락실에서 <철권>, <버추얼파이터>, <킹 오브 파이터 시리즈> 등은 골수팬들을 양산했으며, 온라인게임에서도 이종격투기 게임의 열기는 이어지고 있다. 이미 윈디소프트<겟엠프드>, YNK코리아의 <이지파이터즈>가 있으며, 지금 소개하는 그래텍의 <잼파이터>도 이종격투기를 소재로 한 게임이다. 포스트 겟앰프트도러 당당히 도전장을 내민 잼파이터에 대해서 살펴본다.

  • Using the two-dimensional hydrocode HI-DYNA2D, a calculation on the explosive selding of dissimilar plates(Steel Titanium) was made for the pressure, temperature, velocity and impact ingles adjacent to the collision point during the welding process. The FEM result indicates that optimal stand-off distance of initially parallel set-up is 3-5mm for various values of the explosive thickness. The calculation shows that when the explosive thickness is around 30mm, the temperature of welding point which is strongly related to the metallic jet formation is 2, 000-3, 500K for the given stand-off distance.

  • This paper studied on a theoretical approach to predict structural performances and weight -reduction rates of hybrid bodyshells in case that the material of underframe structure is substituted. To choose other light-weight materials to be substituted for the original underframe material, compressive, bending and twisting deformations are considered under constant stiffness and strength conditions, which derive some new weight-reduction indices from a structural performance point of view. Next, these weight-reduction indices were verified using the finite element analyses of some simplified examples. It is shown that the derived indices to estimate the weight-reduction can be utilized as a good criterion for material substitution of the underframe at a basic design stage.
