급변하는 경영환경에 대처하기 위해 많은 조직들이 ERP(Enterprise Resource Planning) 시스템을 도입 활용하고 있다. 그러나 조직의 적극적인 시스템 도입 활용에도 불구하고 시스템에 대한 이해 부족으로 기대만큼의 성과를 얻지 못하는 경우가 많다. 본 연구에서는 ERP 사용성과에 영향을 미치는 요인을 지식 측면에서 접근하여 조직의 지식 흡수능력의 영향을 검증하였다. 또한 흡수능력 구성요소를 잠재역량과 동기 측면의 요소로 구분하여 이에 대한 선행요인으로서 인적자원관리의 영향을 실증적으로 검증하였다. Many organizations implement ERP(Enterprise Resource Planning) system to compete in the rapidly changing business environment. In contrast to legacy systems, ERP system is applied throughout the organization's work process. Organizations implementing the system expected remarkable improvement in business performance, however, despite aggressive investments, performance of the system was not achieved because of a lack of understanding about the system nature. In this study, the factors affecting ERP system performance was verified in terms of access to the knowledge such as absorptive capacity. Moreover, absorptive capacity was separated by factors in terms of potential competence and motivation, and the influence of human resource management system on absorptive capacity was verified empirically. The study results show that realized absorptive capacity directly affect ERP system performance. On the other hand, potential absorptive capacity indirectly affect ERP system performance through realized absorptive capacity. Potential absorptive capacity was affected by components of human resource management such as education, training and performance-oriented appraisal. Furthermore, performance-based compensation and information communication showed positive influence on realized absorptive capacity. These results presented factors affecting ERP system performance in knowledge context. At the same time, it showed that human resource management components are antecedents of absorptive capacity that implicates for better management. Based on these results, executives can recognize the importance of employees' potential competence related to knowledge and knowledge application based on motivation.

Partial resection of liver is the standard treatment modality in hepatocellular carcinoma(HCC). But the resection of liver is impossible in large HCC, especially with the cirrhotic liver. An alternative treatment for such patients would be orthotopic liver transplantation. We experienced a case of liver transplantation for HCC patient with far advanced disease. The patient had no clinical evidence of distant metastasis preoperatively. We did liver transplantation from a donor who was diagnosed as brain death due to traffic accident. The blood type was compatible and operation was finished successfully. Immunosuppressive treatment with cyclosporine was done and the recipient was known to have hepatitis B. Hepatitis B immune globulin was administered. Immediate postoperative recovery was uneventful but the failure in the of alpha-fetoprotein to normal level was observed. Multiple hot uptake of bone was detected on the bone scan during the follow up and the recipient was expired after 7 months. (Korean J Gastroenterol 1995;27:744 - 748)

최근 증기누설 감시 방법으로 카메라 이미지를 이용한 누설 검출 및 누설 위치 추정방법에 대해 연구되고 있다. 그러나 기존에 연구된 카메라 이미지를 이용한 증기누설 검출 방법들은 차영상 기법을 기반에 두고 있어서 모든 움직이는 물체가 누설로 검출되는 단점을 가지고 있다. 따라서 본 논문에서는 기존 카메라를 이용한 누설 검출 및 누설 위치 추정방법을 통해 취득한 누설 영역 및 추정된 누설 위치를 기반으로 누설 확산 및 누설 위치 변화율 분석 방법을 추가로 수행하여 누설 검출 시 이미지에 검출된 움직이는 물체중 실제 누설만 검출하는 방법을 제안하였으며 실험을 통하여 그 성능을 검증하였다. Recently, leakage detection and leakage location estimation methods using camera images have been studied as a method or monitoring steam leakage. However, the conventional leakage detection methods employing camera images are based on the differences in the captured images. These methods incorrectly detect all moving objects are detected as leakages. Therefore, in this paper, we propose a leakage detection method that utilizes both the leakage area and the estimated leakage location obtained by a conventional method. The proposed method performs leakage diffusion and leakage location rate of change analysis, thereby identifying only the actual leakage. Finally, the proposed method is verified experimentally.

플랜트 배관의 누설감시 시스템은 누설 유무 판단뿐만 아니라 누설의 위치를 신속히 파악하는 것 또한 매우 중요하다. 플랜트 배관의 누설 검출 방법에는 주로 AE(acoustic emission)센서, 마이크로폰어레이 그리고 카메라 영상을 이용한 방법들이 있다. 최근 광역감시 및 원거리감시의 이점이 있는 카메라 영상을 이용한 방법에 대한 연구가 진행되어 왔다. 하지만 기존 카메라 영상을 이용한 방법들은 누설 유무와 대략적인 누설의 위치를 판단하고 있으나 누설이 시작되는 정확한 위치 추정에 대한 연구는 아직 미흡한 상태이다. 따라서 본 논문에서는 카메라를 이용한 누설 검출 방법을 이용해 누설영역을 산출하고 누설 검출 결과를 분석하여 누설 위치를 추정하는 방법을 제안하였으며 실험을 통하여 성능을 평가하였다. It is important to have a pipeline leak-detection system that determines the presence of a leak and quickly identifies its location. Current leak detection methods use a acoustic emission sensors, microphone arrays, and camera images. Recently, many researchers have been focusing on using cameras for detecting leaks. The advantage of this method is that it can survey a wide area and monitor a pipeline over a long distance. However, conventional methods using camera monitoring are unable to target an exact leak location. In this paper, we propose a method of detecting leak locations using leak-detection results combined with multi-frame analysis. The proposed method is verified by experiment.

Given that household food security issues have become the concern of the Korean society, this study aimed to develop food security measures for the Korean population. Based on the literature reviews on previously developed food security measures, the 18-item US household food security survey module (US HFSSM) was adapted. The developed food security measures was assessed by qualitative validity method. It was evaluated and modified by face validity by expert focus groups belong to university, public health center, and government agencies and by cognitive interview by 40 subjects with low household income who live in an urban community and are participants in welfare programs of local districts. Then, it was reviewed and revised by the National Institute of the Korean Language and the advisory committee for nutrition survey of Korean National Health and Nutrition Examination Survey (KNHANES). The results showed that the developed questionnaire items were well adapted by expert focus groups and general subjects, showing the feasibility of measuring food security with the developed measures although there were discrepancies in some expressions of questionnaire items between experts focus groups and general subjects. The study to assess reliability and quantitative validity of the developed food security measures should be further needed to examine its application for KNHANES.
