In this article, I identified many points of commonness and differences at)feared in the fraction units of three conspicuous textbooks -McLellan, MiC and Korea. After that, 1 evaluated these results with reference to more general didactics on which each text-book is based. A background theory of Mc-Lellan's textbook was Dewey's experientialism, and that of MiC was Freudenthal's realistic mathematics education. Through this study, I have reached the fact that these three textbooks could not exhibit the phenomenological wholeness of fraction. Driven by measuring number model which is very abstractive, McLellan's text-book is disregarding the lower level context. MiC textbook, driven by real context, is ignoring higher level model which is close to rational number concept. From an excess of formulation and practice of algorithm, Korea's textbook is overlooking the real context. It is necessary that a textbook which would display the phenomenological wholeness of fraction is developed.

Global(mega) event has increased throughout the 1990s, with the biggest surge occurring in the Asia-Pacific region. Along with this upward trend, competition for more desirable tourists is also surging, so destinations cannot be complacent (Getz, 1997). Event is appearing as the powerful method in the fierce competition around the industry. International events like 99 Hanam Environment Expo have been held annually in Korea since 1991 in which the local government system started. The main roles of event are to enhance the image of communities and attract tourists (Kotler and Haider and Rein, 1993), to strengthen destination attractiveness as drawing power (Mill and Morrison, 1985), and so on. Focused on the destination image, the research (Sirakaya and Sheppard and McLellan, 1997) about the effect of perceived safety at a potential vacation destination showed that destination marketers, travel agents, and hospitality industry members should be concerned with improving their images when such images are negative with regard to safety. Event industry in Korea does not seriously recognize the importance of the safety management against accidents known for tarnishing the destination images. Moreover few safety standards or studies for event industry can be found. This paper investigated the safety factors considered by visitors of 99 Hanam Environment Expo and analyzed the correlation between the safety factors and the demographic characteristics of the visitors.
