The purpose this study was to estimate effects of EPOC and TG/fatty acid cycling on warm water immersion of immediately after exercise. To elucidate the role of fatty metabolism, a sequence of five experiments was performed. Seven physically active, male subjects volunteered to participate in the presented study. The mean values for age, body mass and hight were 25±1.52 yr, 79.2±9.52kg, 177.2±4.62cm, respectively. After giving consent, participant visited the laboratory on six occasion: 1) 30min of treadmill exercise VO2max 55% and a further 60min recovery, 2) 30min partial body warm water immersion in a 39℃ and a further 60min recovery, 3) 30min whole body warm water immersion in a 39℃ and a further 60min recovery, 4) 30min of treadmill exercise VO2mas 55% and in 30min partial body warm water immersion in a 39℃, 5) 30min of treadmill exercise VO2max 55% and in 30min whole body warm water immersion in a 39℃. When compared by recover period within repeat on the base of changes of subjects average body temperature, not effective interactions among repeat. However, partial and whole body warm water immersion immediately after exercise shows it as the best effective exercise for VO2max 55%, partial and whole body warm water immersion. When compared by recover period within repeat on the base of changes of subjects EPOC, effective interactions among repeat(p<.05). Partial and whole body warm water immersion immediately after exercise shows it as the best effective exercise for VO2mas 55%, partial and whole body warm water immersion. The catecholamines concentration was significantly higher partial and whole body warm water immersion than exercise of VO2max 55%(p<.05). The TG concentration and free fatty acid was significantly higher partial and whole body warm water immersion immediately after exercise than exercise of VO2max 55% than Partial and whole body warm water immersion(p<.05). Based on the facts that we have discussed above, human metabolism is increased by both exercise and conditions of immersion and partial and whole body warm water immersion immediately after exercise than exercise of VO2maw 55% shows it as better effective treatment for increasing TG/Fatty acid cycling activation. Due to extremely heavy stress complained by subjects during whole body immersion, it is thought that more researches on it should be required.

사용자 중심의 Identity 관리 기술은 기존에 사이트에서 관리하던 사용자 Identity 를 사용자가 직접 제어할 수 있도록 해주는 기술이다. 본 논문에서는 사용자 중심의 Identity 관리 기술 중 하나인 전자 ID 지갑을 소개하고 전자 ID 지갑의 주요 서비스인 Identity 공유 및 동기화 기술을 설명한다. 그리고 Identity 공유 시 필요한 링크 계약을 설명한다.
이동 멀티캐스트에서 기밀성을 제공하기 위한 키관리 방법
노종혁(Jong-Hyuk Roh),진승헌(Seung-Hun Jin),이균하(Kyoon-Ha Lee) 한국정보보호학회 2006 정보보호학회논문지 Vol.16 No.1
이동 멀티캐스트 환경에서 다수의 이동 호스트가 안전하고 효율적인 멀티캐스트를 실현하기 위해서는 호스트의 이동성 및 무선 영역의 특성을 반영하는 키관리 방법이 요구된다. 본 논문에서는 이동 네트워크 구조를 반영한 KlMM과 WSMM을 제안한다. 호스트의 이동에 따른 핸드오프와 그룹 멤버쉽 변화로 인한 키갱신을 처리하는 키 관리 구조 및 프로토콜을 설명하고, 실험을 통하여 데이터 전송, 멤버의 가입, 멤버의 탈퇴, 핸드오프 등으로 인해 발생하는 지연 시간을 서로 비교하여 각 방법의 장단점을 분석한다. For successfullly deploying many multicast service in the mobile environment, security infrastructures must be developed that manage the keys needed to provide access control to content. In this paper, we propose two methods for designing the key management scheme for the mobile multicast environment. The proposed schemes match the key management tree to the mobile multicast environment for localizing the delivery of the rekeying messages, reducing the communication costs, and solving the handoff problem in wireless region.
