  • It was said that the epigastric region was the outbreak region of chest bind on Shanghanlon. But successive medical men annotated the epigastric region as the chest, which caused the misunderstanding that chest bind was a chest trouble. However Youzaijing, a medical man in Qing dynasty, presented that the epigastric region meant stomach and the middle of stomach did intestines, comparing Dachengqi-tang with Daxianxiong-tang. This view agreed with Huatuo's six-region-transmutation theory. Taojiean and Zhangjingyue also criticized on the six-meridian-transmutation theory, proposing that the change of cold damage didn't go by the fixed rules. This reflected the oriental medical pathologic view that pathogen invaded and advanced to the weak region by the relations between healthy qi and pathogen, and it criticized on the doctrinarian interpretation of Shanghanlon as Neijing. Huatuo insisted that stomach was the final stage of cold damage by presenting that theory. And this theory became a philological basis on Youzaijing's pathologic view.

  • 본 연구는 수도권과 경상권의 비교분석을 통하여 국내 생산자서비스업체의 네트워크 특성을 규명하고, 이런 지역별 특성을 반영한 정책적 시사점을 제시하고자 한다. 지역 간 비교 분석을 위하여 과학기술정책연구원에서 2006년 실시한 서비스 부문 기술혁신조사 결과를 활용하였다. 고객 네트워크의 분석 결과 경상권의 경우 수도권에 비해 서비스를 공급하는 지리적 범위가 제한되어 있으며, 주요 고객 유형은 수도권과 경상권에서 큰 차이가 없었다. 지식 정보 네트워크의 경우 수도권 업체들은 혁신활동을 위한 지식 정보 원천으로 비공식적 인맥 네트워크가 가장 중요한 반면 경상권 업체들은 공급업체가 가장 중요한 지식 정보 원천으로 분석되었다. 또한 경상권 업체들은 수도권에서 혁신 활동을 위한 지식 정보를 얻는 경우가 상당수 있는 것으로 나타났다. 사회 네트워크 기법으로 수도권과 경상권의 지식 정보 네트워크를 분석한 결과 모두 연결성이 낮고 행위자간 분절이 심한 것으로 나타났다. 지역별로 실정에 맞는 생산자서비스 산업을 육성하려면, 수도권은 앞으로 세계적인 생산자서비스의 네트워크에 연결될 수 있도록 지원하고 경상권의 경우는 지역 산업과의 연계를 강화할 수 있는 경영서비스 등에 전략적인 지원이 필요할 것으로 판단된다.

  • Recently, Fire watching and dangerous substances monitoring system has been being developed to enhance various fire related security. It is generally assumed that fire flame extraction plays a very important role on this monitoring system. In this study, we propose the fire flame extraction method of Non-Residential Facilities based on core object extraction in image. A core object is defined as a comparatively large object at center of the image. First of all, an input image and its decreased resolution image are segmented. Segmented regions are classified as the outer or the inner region. The outer region is adjacent to boundaries of the image and the rest is not. Then core object regions and core background regions are selected from the inner region and the outer region, respectively. Core object regions are the representative regions for the object and are selected by using the information about the region size and location. Each inner region is classified into foreground or background region by comparing its values of a color histogram intersection of the inner region against the core object region and the core background region. Finally, the extracted core object region is determined as fire flame object in the image. Through experiments, we find that to provide a basic measures can respond effectively and quickly to fire in non-residential facilities.

  • Comparing with the large containment, the gas can not flow freely within the local compartment due to the small volume of the compartment in case of serious accident, which affects the hydrogen flow distribution, and it will determines the location where high concentration occurs in compartment. In this paper, hydrogen distribution and possible hydrogen risk in the vessel under the different conditions are investigated. The results show that when the initial gas momentum is increased, the ability of gas enters into the upper region of the vessel will be strengthened, and the hydrogen volume fraction in the upper region of the vessel is higher. Comparing with horizontal source direction, when source direction is vertically towards upper space, hydrogen is more likely to accumulate in the upper region of the vessel. With the increasing of steam mass flow, the dilution effect of steam on the hydrogen volume fraction will be strengthened, while the pressure in the vessel is also increased. When steam flow is decreased, the hydrogen explosion risk is higher in the vessel. The experiment data can provide technical support for the validation of the CFD software and the mitigation of hydrogen risk in the containment compartment.

  • Since containment building is the major shielding structure to ensure safety of nuclear power plant, the structural behavior and ultimate pressure capacity of containments must be studied in depth. This paper addresses ambiguous issue of determining free-field position for liner failure by suggesting an expanded free-field region and comparing internal pressure capacities obtained by test data, conservative assumption and suggested free-field region. For this purpose, a practical approach to determine the free-field position for the evaluation of liner tearing is carried out. The maximum principal strain histories versus internal pressure capacities among different free-field positions at various azimuths and elevations are compared with those at the equipment hatch as a conservative assumption. The comparison shows that there are considerable differences in the internal pressure capacity at liner failure within the expanded free-field region compared to the vicinity of the equipment hatch. Additionally, this study proposes an approximate correlation with conservative factors by considering the expanded free-field ranges and material characteristics to determine realistic failure criteria for liner. The applicability of the proposed correlation is demonstrated by comparing the internal pressure capacities of full-scale containment buildings following liner failure criteria according to RG 1.216 and an approximate correlation.

  • In general, the informations of the inner image that user interested in are limited to a special domain. In this paper, as using Wavelet Transform for dividing image into high frequency and low frequency, We can separate foreground including many data. After calculating object boundary of separated part, We extract special features using Color Coherence Vector. According to results of this experiment, the method of comparing data extracting foreground features is more effective than comparing data extracting features of entire image when we extract the image user interested in.

  • Most existing salient object detection algorithms commonly employed segmentation techniques to eliminate background noise and reduce computation by treating each segment as a processing unit. However, individual small segments provide little information about global contents. Such schemes have limited capability on modeling global perceptual phenomena. In this paper, a novel salient object detection algorithm is proposed based on region merging. An adaptive-based merging scheme is developed to reassemble regions based on their color dissimilarities. The merging strategy can be described as that a region R is merged with its adjacent region Q if Q has the lowest dissimilarity with Q among all Q's adjacent regions. To guide the merging process, superpixels that located at the boundary of the image are treated as the seeds. However, it is possible for a boundary in the input image to be occupied by the foreground object. To avoid this case, we optimize the boundary influences by locating and eliminating erroneous boundaries before the region merging. We show that even though three simple region saliency measurements are adopted for each region, encouraging performance can be obtained. Experiments on four benchmark datasets including MSRA-B, SOD, SED and iCoSeg show the proposed method results in uniform object enhancement and achieve state-of-the-art performance by comparing with nine existing methods.

  • In this paper, we propose a visual inspection algorithm to detect can print-errors by using multi-camera and image valuing algorithm. The features of the algorithm are to use four cameras that are arranged with 90$^{\circ}$ between each other and to adopt a synthesized image model which represents whole surface of a can. Using the model, detection process is straight forward, namely it is comparing a partial region of the can to a specific region of the model where is previously marked.
