최근 초고속 인터넷, 모바일, 디지털 컨버전스 단계를 거치면서 유비쿼터스(Ubiquitous) 사회는 점차 가시화 되고 있다. 현재 일상적인 통신뿐만 아니라 경제 및 산업 분야로 다양하게 확산되고 있다. 특히 RFID와 네비게이션(Navigation) 시스템은 국내ㆍ외적으로 많은 분야에 사용되고 있으며 점점 발전하고 경제적?산업적으로 국가 경쟁력 향상에 도움을 줄 것이다. 하지만 이러한 RFID와 네바게이션의 활용 범위를 살펴보면 가장 일반적인 경우에 치중되어있다. 본 논문에서는 RFID와 네비게이션을 사용하여 개별화된 특성과 환경 상태 정보를 반영하고 그것을 사용하는 사용자들의 특성을 고려하여 변화하는 환경에 적응하기 쉬운 시스템을 제안하고 특정 환경에서 어떠한 정보가 이에 활용될 수 있는지를 정의한다. 또한 여러가지 정보를 이용하여 지능형 경로 탐색 및 안내 시스템을 위해 퍼지 로직과 TSP 개념을 적용한다. As it got through the step of super-high speed internet, mobile and digital convergence, the Ubiquitous Society is being attained gradually. Now, it is being variously spread not only the little ordinaries of communication but also fields of economy and industry. Specially, RFID and Navigation system are being used at home and foreign. These are prospected to give assistances that it brings along the competitive power of nation. But inflection range of RFID and Navigation is localized in the most simplest. This paper proposes system to reflect the individual and special quality using RFID and Navigation and to fit easily changing environment. And we studied to use what kind of information in the special environment. We used Fuzzy Logic and TSP for making the intelligence path searching and guiding system with more information.

<B>Purpose:</B> This study comparedthe effectiveness and safety of laparoscopic adrenalectomy with conventional open adrenalectomy for the treatment of pheochromocytoma. <B>Methods:</B> Medical records of 100 patients who underwent surgical removal of pheochromocytoma (open adrenalectomy, n=59; laparoscopic adrenalectomy, n=39) at Samsung Medical Center from June 1995 to August 2007 were retrospectively reviewed. <B>Results:</B> To draw an appropriate comparison, patients with a tumor less than 7 cm in size were evaluated (open adrenalectomy, n=23; laparoscopic adrenalectomy n=31). No statistically significant differences were evident according to age, gender and tumor size. The mean operating time was 158 min for the open surgery group and 114 minfor the laparoscopic group (P<0.01). The mean postoperative hospital stay was 10.4 days following open surgery and 5.6 days following laparoscopic surgery (P<0.01). The mean volume of the estimated blood loss for the laparoscopic surgery group (482 ml) was less than for the open surgery group (mean 229 ml) (P=0.06), and the time to first oral intake was 1.7 days after laparoscopic adrenalectomy and 3.5 days after open surgery (P<0.01). The frequency of using analgesics for postoperative pain after laparoscopic adrenalectomy was markedly lower than following conventional open adrenalectomy. There was no recurrence or complications during the follow-up periods (mean: 30 mon</B>ths). <B>Conclusion:</B> Laparoscopic adrenalectomy offers advantages of less postoperative pain, shorter operative time and a shorter hospital stay as compared with conventional open adrenalectomy. Laparoscopic adrenalectomy for treating pheochromocytoma is a minimally invasive alternative to conventional open adrenalectomy. <B>(Ko</B><B>rean J En</B><B>do</B><B>crine Surg 2008;8:106-111)</B>
