The present study was carried out to elucidate the potential of, chloroform extract of Pandanus (P.) fascicularis Lamk (Family-Pandanaceae) leaves on antinociceptive, behavioral study and anti-inflammatory effects using various animal models The dried, powdered leaves of, P. fascicularis were extracted successively with petroleum ether ($60\;-\;80^{\circ}C$) and chloroform in soxhlet apparatus. The chloroform extract (yield 21.6% w/w with respected to dry powdered plant material) was selected for all experimental procedure. Two models were employed to investigate the effects on nociception, the tail immersion and hot plate method in Swiss albino mice and anti inflammatory effect were investigated by employing the carrageenan induced rat paw edema test in. adult Wister albino rats. Behavioral study was investigated by elevated plus maze method in Swiss albino mice. Results were revealed that the PFCE was found significant antinociceptive effect (P < 0.001) at the dose levels of 100, 200 and 400 mg/kg, orally in mice and produced remarkable antiinflammatory effect (P < 0.001) at the same dose levels used in the rats. Behavioral study of the PFCE has no significant anxiolysis effect when used orally. It concludes that, PFCE possessed remarkable antinociceptive effect and anti-inflammatory effect but no anxiolytic effect on animal models.

The interactive advertisement is already on satellite and cable broadcasting hereafter the introduction of this system is concerned on terrestrial programs. This study is to research the effectiveness of interactive TV advertising focusing on factors of involvement and interaction. Study started for the effect measurement of interactive television advertisement. Interactive television advertisement has different concept than existing television advertisement. Thus, the effect also needs to examine in other methods. Study is mainly focusing on the characteristics of interactive and the experiments, which was based on existing data, for measurement of effect. In the experiments, the characteristics were categorized in a search time, a number of searched pages about interactive television advertisement. The research finds that the involvement of the audience increases when the interaction of advertising attitude, brand attitude, and purchase intentions also increases. And so, a successful interactive TV advertisement results in longer searching hours and greater it visits by the audience when the interaction factors are considered and increased. By study of consumer's characteristics and behavior, a new method of the effect measurement for interactive television advertisement is provided. The new method includes not only existing measurement elements of television advertisement which are attitude on advertising and brand, and customers' purpose, but also the features of interactive television advertisement, which are search time, a number of searched pages. Recently added features provides data of the effect on high/low groups and it contributes to the process of interactive television advertisement.

Recent developments in financial market liberalization and information technology are accelerating the interdependence of national stock markets. This study explores the information spillover effect of the US stock market on the overnight and daytime returns of the Korean stock market. We develop a profitable intra-day trading strategy based on the information spillover effect. Our study provides several important conclusions. First, an information spillover effect still exists from the overnight US stock market to the current Korean stock market. Second, Korean investors overreact to both good and bad news overnight from the US. Therefore, there are significant price reversals in the KOSPI 200 index futures prices from market open to market close. Third, the overreaction effect is different between weekdays and weekends. Finally, the suggested intra-day trading system based on the documented overreaction hypothesis is profitable.
