The international casino game industry has adopted G2S (game to systems) protocol for the future communication standards between slot machines and gaming hosts. G2S protocol uses the internet protocols and XML message format. Not simply G2S protocol replaces the SAS protocol currently in use but with many limitations, but provides diverse application and business chances to the casino industry. In this paper, we introduce the overview of technical features of G2S system, and describe our design and implementation experience of core G2S protocol engine for slot machine devices. The G2S engine provides key protocol stack of G2S (HTTP, XML, and SOAP) and runtime services, using open source softwares and custom classes. The protocol compatibility of the implemented G2S engine is confirmed against an openG2S host software contributed by IGT. Also the measured memory size and perfroamcne is compact enough for typical slot machine hardware specification.

The consumer"s choice options for beer are broaden by importing of foreign beers freely in recent domestic beer market. Especially, young university students are understanding to select various beer in contrast with seniors, but there"s no report about their preference and criteria of selection for beer in spite of them being major consumer of beer. This study derive the Kansei structure and Kansei words for beer by EGM(Evaluation Grid Method), and analysis of preference and evaluation of each beer are carried out by SD(Semantic Differential) method which used Kansei words as a question. The result of this study will be expected to contribute the development of beer moving the consumer.
