The recent development in robot field shows that service robot which interacts with human and provides specific service to human has been researched continually. Especially, robot for human welfare becomes the center of public concern. At present time, guide robot is priority field of general welfare robot and helps the blind keep safe path when he walks outdoor. In this paper, guide robot provides not only collision avoidance but also the best walking direction and velocity to blind people while recognizing environment information from various kinds of sensors. In addition, it is able to provide the most safe path planing on behalf of blind people. 최근 로봇 개발의 현황을 살펴보면 인간과 로봇이 공존하면서 인간이 로봇으로부터 서비스를 받을 수 있는 로봇의 개발이 지속적으로 증가하는 추세다. 그 중에서도 특히 관심을 끌고 있는 것은 복지 로봇에 관한 연구이다. 현재 가장 일반화되어 있는 복지 로봇은 시각 장애인의 주행을 도와주는 안내 로봇이며 장애물을 인식하여 안전한 경로를 제공하는 것을 목적으로 한다. 본 논문에서는 장애물 충돌회피의 기능뿐만 다양한 센서를 장착하여 환경 정보를 파악하여 사용자에게 가장 안전한 이동 방향과 이동 속도를 제시한다. 또한 지도 정보를 이용하여 사용자에게 가장 친숙하고 안전한 주행 경로를 선택하는 안내 로봇을 제시한다.
도서관에서의 상용고객우대제도(FFP: Frequent Flyer Program) 도입

다양한 판매촉진수단들이 기업들에 의해 활용되고 있었으며 그중의 하나인 단골고객보상(Continuity Program) 즉 상용고객우대제도(FFP: Frequent Flyer Program)를 도서관에 도입하고자 하였으며, 이 제도를 통해 도서관은 상용고객을 확보하고, 지속적으로 이들과 우호적인 관계를 유지하여 새로운 신규고객을 유인하는 수단으로 활용하여야 할 것이다.

UIP theory has been quoted as a theoretical framework to explain globalization process of the small and medium sized enterprise, new venture, and a big company. However, because of the environmental change, such as, development of the Internet and decreasing the meaning of national territory, the traditional theories have some difficulties to explain current globalization phenomena. So, the new theoretical perspectives, such as International New Venture(INV) theory and Born-Global firm, are emerged to explain current globalization, instead of traditional theories. The purpose of this study is to investigate the globalization phenomena of Busan-Kyongnam regional firms with the comparison between traditional theoretical perspective(UIP) and new theoretical perspective(INV). For a empirical study, questionnaire survey was used, and 207 copies are used for analysis. The analytical results show that some important factors which affect significantly to the globalization speed of firms, are exposed. These factors are technological level of firms, global orientation of top management teams, support from home country, and psychic distance to target market.

Purpose: In surgical treatment of the medial orbital wall fractures, restoring the original position of the orbital wall is difficult in some cases. Under such condition, the orbital wall is often reconstructed with synthetic material, without bony reduction, which is considered to be the conventional reconstruction. The purpose of this study is to compare the outcomes of anatomical reconstruction, which restores the bony wall to the anatomical position, from that of the conventional reduction in the isolated medial orbital wall fractures. Methods: Thirty patients, who underwent reconstruction surgery for the isolated medial orbital wall fractures from March 2007 to August 2011, were reviewed retrospectively. The surgical outcomes of two groups, the conventional reconstruction group (15 patients) and the anatomical reconstruction group (15 patients), were studied in 2 measurements, a one day before and 6 months after the surgery. The changes of orbital volume were calculated by the images from a computed tomography scan and enophthalmos was measured by a Hertel exophthalmometer. Results: The orbital volume ratio was decreased by an average of 1.05% in the conventional reconstruction group, while in the anatomical reconstruction group, the ratio decreased by 5.90% (p<0.05). The changes in the Hertel scale were 0.20 mm in the conventional reconstruction group, and 0.70 mm in the anatomical reconstruction group. However, the difference in the Hertel scale was statistically insignificant (p>0.05). Conclusion: In conclusion, the anatomical reconstruction technique of the isolated medial orbital wall fracture results in a better outcome than that of the conventional reconstruction, in terms of restoring of the original orbital volume and anatomic position. Thus, it can be considered as a useful method for the isolated medial orbital wall fractures.
