In this paper, we will introduce the general concepts of generalized multiobjective game, generalized weight Nash equilibria and generalized Pareto equilibria. Next using the fixed point theorems due to Idzik [5] and Kim-Tan [6] , we shall prove the existence theorems of generalized weight Nash equilibria under general hypotheses. And as applications of generalized weight Nash equilibria, we shall prove the existence of generalized Pareto equilibria in non-compact generalized multiobjective game.

Microoptics has become the key technology in liquid crystal display systems due to its capabilities of miniaturization and design flexibility. We successfully demonstrate five different microoptical components for enhancing the image quality, providing better functions, increasing light efficiency, and generating 3D images in LCD applications.

본 논문에서는 해커의 불법적인 공격으로부터 전산망을 안전하게 보호하기 위하여 Trusted Information System에서 발표한 공개 버전인 TIS Firewall Toolkit의 방화벽 시스템 구조와 구성요소를 분석하였고 그리고 구축방법에 대하여 기술하였다. 또한 툴킷에서 제공하는 관리 지원 도구인 Port scanner, network subnet ping manager, reporting도구 등을 분석하였다. 본 논문에서 기술한 TIS 툴킷을 이용한다면, 상용 방화벽 시스템을 구축하기 전에 , 보다 쉽게 기관의 보안 정책 개발과 전산망 보호 기술을 확보할 수 있다.

In this paper, we consider the oscillation of the second-order neutral difference equation Δ²(x/sub n/ - px/sub n-r/) + q/sub n/f(x/sub n/ - σ/sub n/) = 0 as well as the oscillatory behavior of the corresponding ordinary difference equation Δ²z/sub n/ + q/sub n/f(R(n,λ)z/sub n/) = 0

In this paper, we are mainly concerned with the classification of nonscillatory solutions for the higher order difference equation and some existence results for some kinds of nonoscillatory solutions.

For a transcendental entire function f(z) with zero order, the purpose of this article is to study the value distributions of q-difference polynomial $f(qz)-a(f(z))^n$ and $f(q_1z)f(q_2z){\cdots}f(q_mz)-a(f(z))^n$. The property of entire solution of a certain q-difference equation is also considered.

Let [$n$] = {1, 2, ${\ldots}$, $n$} be ordered in the standard way. The order-preserving full transformation semigroup ${\mathcal{O}}_n$ is the set of all order-preserving singular full transformations on [$n$] under composition. For this semigroup we describe maximal subsemibands, maximal regular subsemibands, locally maximal regular subsemibands, and completely obtain their classification.

In this paper, we study delayed high-order Cohen-Grossberg neural networks with reaction-diffusion terms and Neumann boundary conditions. By using inequality techniques and constructing Lyapunov functional method, some sufficient conditions are given to ensure the existence and convergence of the periodic oscillatory solution. Finally, an example is given to verify the theoretical analysis.
