Purpose: The usefulness of mechanical bowel preparation (MBP) in colon surgery was recently challenged by many multicenter clinical trials and meta-analyses. The objectives of this study were to investigate current national opinions about MBP and prophylactic antibiotics (PA) and to provide preliminary data for developing future Korean guidelines for MBP and PA administration in colorectal surgery. Methods: A questionnaire was mailed to 129 colorectal specialists. The questionnaires addressed the characteristics of the hospital, the MBP methods, and the uses of oral and intravenous antibiotics. Results: A total of 73 questionnaires (56.6%) were returned. First, in regard to MBP methods, most surgeons (97.3%) used MBP for a mean of 1.36 days. Most surgeons (98.6%) implemented whole bowel irrigation and used polyethylene glycol (83.3%). Oral antibiotic use was indicated in over half (52.1%) of the responses, the average number of preoperative doses was three, and the mean time of administration was 24.2 hours prior to the operation. Finally, the majority of responders stated that they used intravenous antibiotics (95.9%). The responses demonstrated that second-generation cephalosporin-based regimens were most commonly prescribed, and 75% of the surgeons administered these regimens until three days after the operation. Conclusion: The results indicate that most surgeons used MBP and intravenous antibiotics and that half of them administered oral PA in colorectal surgery preparations. The study recommends that the current Korean guidelines should be adapted to adequately reflect the medical status in Korea, to consider the medical environment of the various hospitals, and to establish more accurate and relevant guidelines.

Leakage sensing and detection system for special waterworks pipe is developed and applied in the field with RTD-2000 equipment. RTD-2000 is the pulse reflection type leakage-distance calculation system of embedded devices. This RTD-2000 have to be placed at proper location for the effective leakage monitoring and construction cost. In this paper, pipe networks selection technique and install-location selection algorithm is proposed for efficient leakage sensing pipe network construction. Also construction information including DB model for the effective leakage location finding system management algorithm is proposed. Finally, proposed algorithm and network selection technique's effectiveness is verified through the actual site application.

The concern with management of underground facility has been growing for the last several years. As several researchhave been made on management for waterworks pipe using TDR technology. In contemporary, development of ITtechnology in all areas of a large ripple effect technology is the Augmented Reality(AR). Also, various facility managementsystems using AR technology are studied and developed with the advancement of the smart device. AR is essentialtechnology for the implementation of facility management system, which has GPS, camera and sensor of smart device. Andit manages data of underground facility with pipe-networks segment DB effectively and provides practical effectiveness ofentire monitoring system through GPS receiving module and sensor network communication on AR. In conclusion, thispaper proposed facility database for AR-based management system using SQLite. Proposed database is tested through thesystem simulation.

인구증가와 발전으로 도시 집중화 현상에 따라 수도의 수요증가가 가속화되는 상태이다. 특히 물 부족현상 및 수질악화로 인한 수원확보도 어려워지고 있는 실정이다. 누수로 인한 막대한 손실을 줄이고자 컴퓨터와 인터넷을 이용하여 누수가 발생할 경우, 누수 여부를 판단하고 중앙 모니터링 센터에서 관리할 수 있는 시스템이 필요하다. 본 논문에서는 누수감지관과 TDR을 이용한 원격 상수도관망 누수 감지 시스템을 제안하였다. 유효성을 입증하기 위해 300mm 3-레이어 강관으로 파이로트 시스템을 구축하여 시뮬레이션 하였다. Demand of water is increased according to city centralism phenomenon in population and development. In this progress, guarantee of enough water is important factor for water supply policy. For the detection of exact water leakage point, an epochal sensing technique using computer and internet is required, so, the water pipe having sensing wire and sensing technology using TDR(Time Domain Reflectometer), is proposed in this paper. For the prove of effectiveness of this system, pilot system using 300mm 3-layer coated steel pipe is made and tested.
