An automorphism group of a graph is said to be $s$-regular if it acts regularly on the set of $s$-arcs in the graph. A graph is $s$-regular if its full automorphism group is $s$-regular. In the present paper, all $s$-regular cubic graphs of order $10p^3$ are classified for each $s{\geq}1$ and each prime $p$.

무선 ATM의 MAC 프로토콜은 독립적으로 분산되어 있는 이동 단말기들을 대상으로 ATM이 추구하는 진정한 의미의 통계적 다중화 기능을 무선 매체를 통해 확장하는 역할을 한다. 이와 같은 매체 접근 제어 프로토콜을 통해서만 멀티미디어 서비스 특성에 따라 동적으로 변하는 대역 요구 사항과 지연 시간 및 셀 손실 등의 서비스 품질을 동시에 만족시킬 수 있으며, 이동 단말기들이 채널을 공평하면서도 효율적으로 사용할 수 있는 접속 환경을 제공할 수 있다. 따라서, 이와 관련한 유럽의 ACTS 프로젝트 및 제외국에서의 기술 개발 사례와 ATM Forum WATM-WG에서의 표준화 동향을 분석하여 향후 무선 ATM 구현에 필요한 요소 기술로서의 매체 접근 제어 방식의 설계 및 구현 방안에 대해서 고찰함으로써 향후 연구 방향을 제시하고자 한다.

Microglial cell is a monocyte involved in the brain, which acts for a primary immune reaction and phagocytosis. Microglia has also been considered to have a great role in AD pathogenesis due to its intact inflammatory and phagocytic responses against foreign invaders. In the study, we tried to investigate the modulation of activation of microglia using Rg1, a class of ginsenoside from red ginseng. which are known to protect neuron cells. (omitted)

A H$\_$.inf./ contro theory was applied to motor speed control of two-mass system to get controller which acts effectively with control object including uncertainties. The H$\_$.inf./ control problem was composed and solved. After that, numerical simulation were executed to confirm ability of the controller which compared with PI controller.

An agent is a computer program that acts autonomously on a computer system. A mobile agent is not bound to the system where it begins execution. It has an ability to transport itself from on e system in a network to another. Mobile agent system solve the network traffic problem. Moreover, the agent may utilize the object services of the destination agent system. In this study the mobile agent system is introduced to support security service.

In this paper, we introduce the software and hardware of the measuring system for performances of traction and braking in KTX(Korea Train eXpress). The measuring system focuses on the verification of the performance and acquisition of test data. The software controls the hardware of the measuring system, performs the analysis and calculation of measurement data and acts as interface between users and the hardware. For this purpose, three programs, such as a measuring program, a back-up program and a post-processing program, have developed.

In rock mass, great many discontinuity exists that is caused to various factors of formation. But these are parted to some groups by specific category, so called these as discontinuity set. This discontinuity set has unique special characteristics in original rock mass, but for the moment, differ the special quality if external force such as digging etc. acts, specially, change of stress condition. Also, geometrical relation change between discontinuity orientation and direction of excavation various characteristic is seen. Therefore, we introduce here the useful chart that can do specification these relation.

The need for the effective flame retardant finishing for synthetic fiber Is required. This paper is focussed on the analysis of physical properties of nylon 6 fabric treated with tris(2-chloroethyl) phosphate(TCEP) in comparision with the untreated fabric. In order to evaluate the flame retardance effect, limiting oxygen index and burn rate were determined. Above 20% add-on of TCEP on nylon 6 fabric, reasonable flame retardancy was observed. Thermal stability of the treated nylon 6 fabric was evaluated by TGA. It seems that TCEP acts via a condensed phase mechanism. Tenacity and moisture regain of the treated fabrics were not changed and washfastness of those was excellent.
