Introduction

KGSYS (Korean Graduate students SYStem research group ) is a non-official research group by Korean Ph.D students in Computer Science and Electronic Engineering at University of Maryland, interested in researche areas relevent to System, Network and Network Security.

Group readings and seminars about various fields in System, Network and Network Security has been conducted under the name of KGSYS since 2002.

The group has been developed from a small reading group by three Ph.D students in Dept. of Computer Science at Univ of Maryland in 2002. They started with the book "TCP/IP Illustrated Vol 2" by Wright Stevens and agreed to keep the collaboration in researches.

Administrative Information

ARTICLE SELECTION PROCESS

 - 5 distinct Articles from "IEEE Communications Mag" will be voluntarily 
   selected by members' own favor, every 2 issues per meeting in reverse 
   order of issue ( present to past )

 - When attendants are less then 5, some members select two articles 
   while others select one to make 5 articles.

 - Selections should be distinct and a first-come-first-served basis.

ARTICLE SELECTION CRITERIA

 - Exclude short editorials or book reviews of 1-2 pages

 - There is no restriction about the topic. The purpose of the meeting
   is to overview the research trend in various areas.

 - At the meeting, each attendant presents his selection for 15-20 min 
   per article. Total expected time is 2 hours excluding pizza fest.

 - Any other presentation of Article/Topic/Introduction from any other 
   source is welcome if it is reported for the selection.
   ( eg, Yeo is considering MPLS to present in near future )

ETC
