미래의 기업 환경은 유형 자산으로서의 물질적인 자산보다는 지적재산권 등의 무형 자산에 대한 중요성이 더욱 강조될 것이다. 지적재산권 중 특허의 가치를 통하여 기업의 성과가 변화함을 보인 많은 선진국의 사례 연구-Machluo(1958)으로부터 시작하여 Mansfield(1965), Beck. R(1976), Parker. J(1978), Rosegger. G(1980), Scherer. F(1980) 등 1990년 이후는 무수히 많음-는 미래 기업 경쟁력이 질적 가치가 우수한 특허를 얼마나 보유하고 이를 얼마나 효율적으로 관리하는가에 달려있음을 보여주고 있다. 본 연구는 국내 화학기업의 특허관리 유형을 5가지 특허 지표들-국내특허출원건수(relative patent applications), 국내특허등록건수(patent granted), 유효특허건수 (valid patents), 집중도(concentration of patents in subclass), 국제특허출원건수(overall international patent applications)-을 통하여 구분하였으며, 이들 변수를 가지고 군집화 하였을 때 각각에 해당하는 클러스터에서 기업성과에 차이가 나타나는지 알아보았다. 본 연구에서 특허를 기업성과와 관련시켜 설명한 점은 기술혁신 능력 내지는 기술경쟁력을 측정하는 척도로서 특허를 바라본 것이며, 특허의 전략적 관리와 활용이 독점적 시장 우위의 확립과 경제적 성과 향상, 통합적인 경쟁력 강화 측면에서 기업의 성공을 가져올 것으로 보기 때문이다.

The study was done with the hypothesis that internet users' evaluation of hotel web sites would be differed depending on the class, location, size, ownership, and guest type of hotels. The study found that location, guest type are loosing their strategical importances in the internet marketing. However, class, size, and ownership are still favorable marketing tools with the internet. The study also found that the location gap between metropolitan and local hotels is decreasing, and the chance of attracting potential customers will be evenly offered to the two type of hotels in the internet oriented business environment.

The question of how to make strategic alliances work successfully is becoming increasingly important as more and more firms regard cooperative relationships as a means of improving their competitive position. The objectives of this research are to determine whether certain liner shipping alliance forms are more successful than others, whether the relative importance of reasons for successful liner shipping alliance varies with the different reasons, and whether the relative importance of reasons for alliance success varies with the form liner shipping alliances. The research findings have shown that the majority of liner shipping alliance forms, utilised by respondents in this survey, experienced a relatively high level of success. However, success was shown to be dependent upon a variety of factors and the reasons for successful alliance varied with the form of alliances.

Purpose: This study are to analyze and to compare between pupillary size, reaction time, refractive error, corrected vision, dominant eye, static visual angle (SVA) and kinetic visual acuity (KVA) of male and female college students, to measure KVA of them in full correction and to identify changes of KVA by +0.50 D and -0.50 D spherical power addition respectively in full correction condition. Methods: KVA, SVA, pupillary size, reaction time, refractive error, corrected vision and dominant eye of 40 male and 40 female optical science students were measured by utilizing KOWA AS-4A, reaction time measurement program, subjective refractometer, and objective refractometer, and KVAs were measured when +0.50 D/-0.50 D were added in both eyes respectively. Results: Binocular KVA of whole subjects was $0.45{\pm}0.22$, and in monocular KVAs were $0.36{\pm}0.19$ for right eye and $0.34{\pm}0.19$ for left eye, and binocular KVA was significantly higher than monocular KVA. It appeared that the better SVA was, the better KVA was in significant way, and in terms of refractive error the less myopia amount was, the better KVA was, but it was not significant statistically. The lower astigmatism was, the slightly and significantly higher KVA was when dividing between equal or less than -1.00 D astigmatism group and over -1.00 D astigmatism group. In resulting from correction condition of refractive error KVAs were $0.45{\pm}0.22$ for full correction, $0.26{\pm}0.15$ for +0.50 D addition, $0.48{\pm}0.22$ for -0.50 D addition which indicates that KVA in over myopia correction was significantly the highest and followed by full correction and under correction. Similar findings were revealed in both male and female, and KVA of male was better than female in comparing between male and female. There was no significantly different KVA between dominant eye and non-dominant eye. Conclusions: Accordingly, it is concluded that KVA is related with far distance SVA, astigmatism amount, and refractive error amount except a dominant eye. Through this research, it was found that prescription for enhancing KVA is to make full correction or to overcorrect slightly myopia.

This study investigates how cultural differences between countries affect bilateral trade volumes, using Hofstede's cultural index that reflects nations' cultural characteristics. Empirical analyses of the impacts of Hofstede's five cultural characteristics on bilateral trade volumes are conducted either in each separate equation or simultaneously. Bilateral trade data of OECD countries plus China as of year 2010 is used for regression analysis on gravity model. Regression results from individual equation for each cultural index variable show tthe smaller the index gaps of power distances and uncertainty avoidance among countries, the larger bilateral trade volumes. On the contrary, the larger the index gaps of long-term orientation among countries, the larger bilateral trade volumes. If five Hofstede cultural indexes are regressed in a single equation, however, only variables of power distance and long-term orientation are significant. The analysis largely confirms that bilateral trade among countries with similar culture have much potrential to grow. It implies that policy actions for cultural proximity are very important for furthering bilateral trade.

Metabasites and metapelites in the Mungyong area were intruded by Cretaceous granites with radius of 4-8 km. As the distance from granite body increases, the mineral assemblage of metabasite changes from amphibole + plagioclase through amphibole + plagioclase + epidote to amphibole + plagioclase + epidote + chlorite. The compositional variations of amphibole and plagioclase according to the change of metamorphic grade and bulk rock compositions are very complex. Towards the Mungyong Cretaceous granite body, the mineral assemblage of metapelite changes from chlorite+ muscovite(ch1orite zone) through biotite + chlorite + muscovite(biotite zone) to andalusite+biotite + muscovite${\pm}$chlorite or cordierite+ biotite+ muscovite${\pm}$chlorite(cordierite zone). The estimated metamorphic conditions of cordierite zone are 480~$580^{\circ}C$ 1.5-3.3 kb. The theoretical study on the thermal metamorphism caused by the Cretaceous granite with radius longer than 4 km in the Mungyong area suggests the followings: The degree of metamorphism is mainly determined not by the size of granite body but by the temperature of granite intrusion; The country rocks within 2 km from Cretaceous granite have undergone metamorphism with temperature higher than $500^{\circ}C$, which is consistent with the petrological study in the Mungyong area. Mungyong Cretaceous granite caused a low P/T thermal metamorphism to the country rocks; the amphibolite facies metamorphism to the country rocks within 1-2 km from the granite body and the epidote-amphibolite and greenschist facies metamorphism to the country rocks within 2-5 km.

This paper compares the price strategies of Korean internet retailers against those of Korean traditional retailers in regard to books, CD\\`s, cosmetics, softwares, PC and peripherals, and electronic home appliances. The data shows that the average prices of books, CD\\`s, and cosmetics are cheaper in the internet market than in the traditional market when there is a large purchase. However, when there is a small purchase, the average prices of books and CD\\`s are more expensive in the internet market than in the traditional market. In other cases, the difference of the average prices in the two markets was negligible. When there is a large purchase, the dispersion of prices of books is smaller in the internee market than in the traditional market. In other cases, the dispersion of prices is smaller in the internet market than in the traditional market, but the difference was negligible to be statistically significant. The findings imply that internet retailers generally pursue a specialization strategy against traditional retailers by factors other than prices. Internee retailers seem to pursue price competition against traditional retailers only for large purchases in some cheap commodity industries. It is also found that the internet shopping-malls managed or owned by existing traditional retailers or manufactures are rare and are operated dependently on existing distribution channels. The findings also imply that the Internet market begins to be established only in some cheap commodity industries and the Internet market has yet to be generally established in Korea.
