The muscarinic effects of carbachol were compared on the isolated ileums of guinea-pig, rat and rabbit to elucidate the underlying mechanism of species differences in sensitivity for carbachol. The ED$\_$50/ value estimated on the guinea-pig ileum was 4 to 6-fold lower than those obtained on the rat and rabbit ileums, but the K$\_$A/ values of carbachol determined by functional assays were almost identical with 12-l7 ${\mu}$M in all of three ileums. The competition data of carbachol for [$^3$H]QNB binding were best described by a two-site model yielding the Ki values of 0.4-0.6${\mu}$M and 12-16${\mu}$M for high(K$\_$H/) and low(K$\_$L/) affinity sites, respectively. The low affinity dissociation constants(K$\_$L/) of carbachol determined from receptor binding studies thus were not significantly different from the K$\_$A/ values estimated from functional studies. The percentage of receptor occupation that carbachol requires for half-maximal response was approximately 3 to 5-fold lower in guinea-pig compared to rat and rabbit whereas the density of muscarinic binding sites per gram of ileum measured by [$^3$H]QNB saturation isotherms was two-fold higher in guinea-pig than that in rat and rabbit. Therefore, the numbers of muscarinic receptors occupied at ED$\_$50/ values of carbachol were about two-fold lower in guinea-pig, suggesting two-fold greater intrinsic efficacy. These results indicate that the guinea-pig ileum has higher muscarinic receptor density and greater intrinsic efficacy for carbachol than the rat and rabbit ileums.

As the informationized society develops, for companies to be industrially competitive in global competition, innovation of business administration through informationization is a nation-wide task that must be driven. Small-to-mid size companies also tend to recognize the need for informationization and build the information systems, improving their informationization levels. To reduce errors in bringing in and running the information systems and increase efficiency In using them, the need for the standard and guide for informationization in small-to-mid size companies has increased. Accordingly, the national office of small and medium business administration has developed the informationized management system (IMS) certification standard in order to provide a national motive to secure the means for management innovation of small-to-mid size companies and have them recognize informationization as a business strategy. Now, there arises the need for the IMS certification standard, which was developed in early 2000, due to changes in environments of small-and-medium businesses and problems that have been revealed in field applications. In this research, we have examined the current situations of informationization in small-and-medium businesses that were revealed by the 2005 survey on the levels of informationization in small and medium business, have drawn the problems that have occurred in the process of applying the IMS in many small-to-mid size companies, have devised the measures against those problems, and have proposed a new IMS certification standard that reflects those measures. This research has proposed only the direction for development of the IMS certification standard. Future researches should deal with detailed items and criteria for evaluation and continuous improvement of them.

Purpose - The purpose of this study was to develop a motivation scale for participation sport tourism and to produce implications of potential use of MSPST for sport tourism distribution emphasizing the needs of sport tourists and the functions required to satisfy those needs. Research design, data, and methodology - The Motivation Scale for Participation Sport Tourism (MSPST) was developed in three stages. A literature review generated 8 dimensions with 42-items in the first stage. Second, an expert review phase refined the initial item pool, which resulted in 35 items. Result - Exploratory factor analysis was employed to produce an 8-factor, 28 item pool. The reduced version was confirmed via structural equation modeling, indicating an acceptable model of fit. The final MSPST consisted of 8 dimensions of motivation, including friendship, family, solitude, challenges, intrinsic, achievement, nature, and competition. Conclusions - The MSPST is a valid and reliable scale of tourists' motives for participating in sports. The results supported the suggested measures of motives associated with participation sport tourism regarding construct, convergent and discriminant validity. A body of knowledge about motives provides insights for policy-makers seeking to support distributional industries for sport tourism and finally to promote economy on both regional and national levels.

We reported the direct effect of intrinsic surface energy of dry adhesive material to the Van der Waals and capillary forces contributions of the total adhesion force in an artificial gecko-inspired adhesion system. To mimic the gecko foot we fabricated tilted nanohairy structures using both lithography and ion beam treatment. The nanohairy structures were replicated from Si wafer mold using UV curable polymeric materials. The control of nanohairs slanting angles was based on the uniform linear argon ion irradiation to the nanohairy polymeric surface. The surface energy was studied utilizing subsequent conventional oxygen ion treatment on the nanohairy structures which resulted in gradient surface energy. Our shear adhesion test results were found in good agreement with the accepted Van der Waals and capillary forces theory in the gecko adhesion system. Surface energy would give a direct impact to the effective Hamaker constant in Van der Waals force and the filling angle (${\varphi}$) of water meniscus in capillary force contributions of gecko inspired adhesion system. With the increasing surface energy, the effective Hamaker constant also increased but the filling angle decreased, resulting in a competition between the two forces. Using a simple mathematical model, we compared our experimental results to show the quantitative contributions of Van der Waals and capillary forces in a single adhesion system on both hydrophobic and hydrophilic surfaces. We found that the Van der Waals force contributes about 82.75% and 89.97% to the total adhesion force on hydrophilic and hydrophobic test surfaces, respectively, while the remaining contribution was occupied by capillary force. We also showed that it is possible to design ultrahigh dry adhesive with adhesion strength of more than 10 times higher than apparent gecko adhesion force by controlling the surface energy and the slanting angle induced-contact line of dry adhesive the materials.

The category killer that has been rapidly growing mainly in advanced countries since early 1990's, is a mew distribution model which aims for obtaining market controlling power by surpassing competing businesses in a specific area of products. The domestic situation of category killers is very different from that of advanced ones abroad since it has just been introduced into the Korean market. At the moment, there are only 10 or so companies operating in the market : Geopyung's , Taeheng's , Midopa's , of Sinsegye Department store, adn of Yerim International. The purpose of this study is to examine problems of domestic companies in the present market by analysing the operation status of category killers in domestic markets as well as foreign ones, and to suggest a counter-strategy of category killers for the distribution environment of the 21st century to improve the competitiveness of Korean distribution industry. The competitiveness of category killers lies above all in products lines. Category killers are equipped with the greatest number of products lines among those of competing businesses due to maximized product selections in an limited range. Another source of competitiveness may be found in balanced strategy positioning. That is to say, category killers are in a position where they can adjust policies towards any of the three purposes while aiming at them altogether : prices of discount stores, products range of specialty stores, and customer service level of department stores. It is also necessary for efficient store operation to use information technology such as electronic data interchange (EDI), electronic pose system(EPOS) and electronic funds transfer (EFTPOS). As for the cost structure, category killers can gain an advantage over other business since operating cost of various sections can be saved. There are, however, certain risks that category killers with strong competitiveness may influence on other businesses a great deal and even facilitate their decline. Yet it seems that the growth of category killers will be more viciously restrained by continuous challenges from other businesses. The distribution industry is supposed to develop through such competition and restraint.
