IFGT 의 실증적인 lower bound 에 관한 분석
김경옥,이재욱 한국경영과학회 2010 한국경영과학회 학술대회논문집 Vol.2010 No.6
지난 몇 십 년간 저장되고 있는 정보량은 폭발적으로 증가하였다. 이와 함께 빠르고 효과적으로 이들을 분석하는 알고리즘의 필요성이 같이 증가하고 있다. 하지만 지금까지 개발된 커널머신은 사용하는 데이터의 수가 증가하면 매우 많은 계산 비용을 요하여 대용량 데이터에 적용하기에 어려움이 따른다. 이 점을 개선하기 위해 개발된 IFGT 는 계산 시간이 O(MN)이 아니라 O(N+M)을 따라 증가하기 때문에 대용량 데이터를 상대적으로 빠르게 처리할 수 있다. 본 발표에서는 데이터의 차원과 개수에 따른 IFGT 계산 시간의 lower bound 를 실증적으로 알아보고 다른 방법과 비교하여 데이터의 특성에 따라 어느 방법으로 계산하는 것이 적합한지 제시하고자 한다.

현대사회는 산업화로 인해 다양한 재해를 접하게 되고, 그 피해를 최소화하기 위해 많은 연구가 이루어지고 있다. 재난의 예방을 위해서는 위험 상황에 대한 정확한 판단과, 그 상황 발생에 즉각적인 대처가 가능한 시스템의 개발이 필요하다. 현재 유비쿼터스 환경하의 상황정보시스템에 대한 다양한 연구들이 진행되고 있다. 그러나 다중 상황에 대한 모니터링 및 처리가 가능한 시스템에 대한 연구가 미흡하며, 이로 인해 다중상황에 대한 신속한 대처가 이루어지지 않고 있다. 본 논문에서는 다중상황의 처리를 위해 각종 센서로부터 데이터를 취득하여 시간 마킹 처리 후 데이터베이스에 저장하고, 사용자의 요구에 따라 추상화된 Context를 사용자에게 제공할 수 있는 다중상황 처리를 위한 RFID/USN 미들웨어를 시스템을 설계한다. Modern society encounters various accidents due to industrialization and numbers of studies are going on to minimize damage from accidents. For prevention of accidents, it is necessary to design a system that helps making accurate judgment in emergency cases and is able to instantly manage each contingency. Various studies are currently going on contingency information system under ubiquitous environment. However, there have not been sufficient studies on the system that is able to monitor and process multiple contingencies and thus we still have difficulties in coping with multiple contingencies promptly. This study designs a RFID/USN middleware system for multiple contingencies control that receives data from various kinds of sensors and saves data after time marking thus is able to provide conjectured context when requested.

This study analyzes Donggaechaek(洞契) and Chibuchaek(置簿冊) in the region of Yuchi, Jangheunggun, Jeonlanamdo and inquires into the background, purpose, structure, component and finances of Yuchi Donggae. The founding dates of Yuchi Donggae are not sure. According to the existing documents and oral materials, it is estimated to be about Imran. After being founded, Yuchi Dongaae repeats operation and suspension several times. In the early 19th century, it is restored by the request of people. After that, Yuchi Donggae is operated in the colony of Japan, suspended in the Korean War and then restored in 1953 so continues till now. The material value of Yuchi Donggae is regarded as the important data for restoring the history and culture of Yuchi region because Yuchi Donggae reflects the experience of people in the Korean War, the process of restoration of the village after the war and all the social circumstances happened in that village. Yuchi Donggae is composed of Gaewon(a member of a credit union) and Imwon(an official). The head of a household who lives in the village can be Gaewon. The conditions for joining which is called as "Myunghajeon(名下錢)" or "Hohajeon(戶下錢)" are to pay 3 seung to 5 seung or 500 whan to 1,500 whan. One who moves into another village or doesn't join the meeting without any reason or the missing are dismissed from membership. Yuchi Donggae is run by Yusa(有司)). Jeonjoyusa(正組有司) who cares for grain, Jeonyusa(錢有司) for money and Gangsinyusa for a religious service take a role as Gaejang(a chief), Bugaejang(a vice-chief), Chongmu(a manager), Gansa(secretary-general) and Gomun(a counselor). Gaejang is selected by the state of virtue and scholarship. Other Imwon under Gaejang are elected by votes. The term of Imwon is 1 year and the reappointment is possible. And the finance of Donggae is made up by an entrance fee of Gaewon; a rental fee of products of the village such as a field, a forest land a fish-farm a sunshade and tableware; and loan-sharking. The function of Yuchi Donggae varies according to the flow of an age. Before the Korean War, Donggae gives Importance on the mutual aid and the inheritance of virtues of Yeossihyangyak(呂氏鄕約). In the colony of Japan, Donggae supports the fund for education to help a patriotic movement and a cultivation. In 1950s, it concentrates an effort on solving the urgent problems directly aaer the war. As a result, the structure of Hyangchon(a county village) in Yuchi region is made up of Sangpogae(喪布契), Sanlimgae(山林係), Chinmokgae(親睦契) and Whasugae(花樹契) besides in 1960s. As Hyangchon gets more stabilized in 1570s and 1980s, Yuchi Donggae considers the public welfare for villagers. Donggak which is the resting place of villagers, the place for the old, a bank, a waterway and a medical office are built. As the construction of Tamjindam and the state of rural exodus lead to the depression of Yuchi Donggae in 1990s, Gaewon performs the times-and∼seasons custom and the ceremony selecting the holiday such as Yudu(流頭), Chilseok(七夕) and Baekjung(百中), promotes the compromise and well-being of villagers and strengthens the structure and function of Yuchi Donggae.
