The international and domestic revenue keep growing constantly, and nowadays the international casino game industry is getting upgraded utilizing IT technology. In contrast, due to many constraints and limitations, Korean IT society has not paid attention to the casino IT area. Slot machine is one of popular gaming systems in the casino. In this paper, we present our design and implementation of protocol analysis system for SAS 6.0 protocol. Slot machine accounting system (SAS) is an international standards protocol and provides auditing, management, and additional service for slot machines. Our protocol analysis system design experience provide in-depth understanding on slot machine and its accounting requirement than a simple conceptual introduction of protocol. Also, the key difficulties of SAS protocol implementation and performance requirement is examined. Our system successfully works in small portable embedded system and showed its benefits, showing benefits for debugging and reverse-engineer a real work problem with commercial system. The engine of the analysis software will be the base of real SMIB (slot machine interface board) system for commercial use.

미취학 아동의 창의적 사고, 다양한 경험 기반의 학습 활동, 그리고 인성 및 감성 중심의 교육에 대한 욕구를 충족시켜줄 수 있는 새로운 교육 방식으로써 체감형 교육 방식의 보급이 활발해지고 있다. 체감형 학습은 사용자의 움직임이나 감각을 통해 디지털 교육 콘텐츠를 조작하는 인간-컴퓨터 인터랙션을 활용한 교육 방식이다. 그러나 사람의 움직임이나 목소리 같은 음성/영상 인식의 정확도가 높지 않아 실제 교육 시스템 적용에는 한계를 보인다. 이러한 한계점의 극복을 위해 인간과 서비스 콘텐츠 사이에 매개체를 두고 이를 통해 사람의 움직임을 가속도, 각속도와 같은 숫자 값으로 변환/전송하여 인터랙션 하는 매개 인터페이스 개념이 제안된다. 본 연구에서는, 교육 시스템의 대상인 미취학 아동의 행동을 관찰하고 프로토콜 분석을 통하여 사용자 중심의 매개 디바이스 디자인 요구사항을 제안한다. 분석 결과, 미취학 아동들은 물체를 조작하는 데 서툴고, 무의식적으로 물체를 만지작거리거나 기대는 행동을 보였다. 또한 물건을 사용할 때 그에 종속되어 행동의 부자연스러움을 보였다. 따라서 체감형 교육을 위한 매개 디바이스는 사용자의 익숙하지 않은 조작을 보조할 수 있어야 하며, 디바이스 사용 중에도 자연스러운 행동을 유지할 수 있도록 디자인되어야 한다.

This study was aimed to establish the evaluating protocol and standard assessment for genetically modified (GM) hot pepper and to find out a proper statistic method to analyze for equality of agricultural characters between GM and non-GM pepper lines. GM and non-GM hot pepper lines were cultivated in two GMO fields in the middle region of Korea and total of 52 agricultural characters were collected during the plant growing season for 4 years, 2007 to 2010. Levene’s test was conducted to confirm the homogeneity of raw data before statistic analysis. Two-way ANOVA in the multivariate tests and t-test were conducted to analyze 52 agricultural characters in order to find out the equality between H15 and P2377. From the statistical analysis through two-way ANOVA, 16 out of 16 plant growth traits, 9 out of 18 green fruit traits and 7 out of 18 red fruit traits among 4 years and 9 out of 16 plant growth traits, 4 out of 18 green fruit traits and 3 out of 18 red fruit traits between H15 and P2377 have shown the statistic differences. With the same raw data of 52 agricultural characters, t-test was also conducted. Based on the result from t-test, only 1 out of 16 plant growth traits, 2 out of 18 green fruit traits and 1 out of 18 red fruit traits have shown the differences between H15 and P2377, so that it was concluded that there is no statistic difference between H15 and P2377 in terms of agricultural characters. Also, the t-test is a proper statistic method to analyze each trait between GM and its control lines in order to evaluate agricultural characters.
