Purpose: The purpose of this study was to determine the incidence of antral septa and the accuracy of panoramic radiograph in identifying maxillary sinus septa. In addition, when panoramic radiograph led to a false diagnosis of more than majority, we analyzed findings of the panoramic radiograph. Patients and methods: This study included 180 patients who were radiographically examined before the surgery was done using both panoramic and computerized tomographic radiographs(CT scan), Samsung Medical Center from April 2003 to March 2006, and examined the incidence of antral septa, the false diagnosis rate of panoramic radiograph, and radiographic characters in case of false diagnosis. Only those bone lamellae were considered as septa that showed a height of at least 3.0mm. It was thus possible to exclude the alveolar recess. One oral and maxillofacial surgeon(OMFS) determined the presence or absence of sinus septa in CT scan, and five OMFS determined the presence or absence of sinus septa in panoramic radiograph. Results: The septa were observed in 81 of 360 sinuses(22.5%). All septa were oriented in a buccopalatal plane. More or less greater prevalence was observed in the second molar region(38.2%) but no predominant location was found. Panoramic radiograph led to false diagnosed septa in 361 of 1800 cases(20.1%). In case of false diagnosis of more than majority, superimposed image on zygomatic process was 44.1%, faint image in the region not related to sinus lifting 26.5%, faint image in the region related to sinus lifting 17.6%, and misconception for superimposed image 11.8% Conclusion: In this study we could get clinico-anatomical information of septum in the maxillary sinus. Compared to CT scan, panoramic radiograph can not clearly differentiate the sinus septa, but we consider that panoramic radiograph may improve its usefulness if we take additional modified panoramic radiograph and clinical exam.

Since the interior shape of a pressure regulator is complex and the change of fluid resistance at each operation condition is rapid and big, the pressure regulator can become the major factor that causes big loss in pipelines. So the suitable pressure regulator modeling by each operation condition is important to obtain reliable results especially in small scale pipeline network analysis. And in order to prevent the condensation and freezing problems, it is needed to confirm both whether temperature recovery is achieved after passing by the pressure regulator's narrow neck and how much amount of low temperature area that can cause condensate accumulation is distributed by various PCV models at every inlet-outlet pressure ratio. In this research, the numerical model resembling P company pressure regulator that is used widely for high pressure range in commercial, is adopted as the base model of CFD analysis to investigate pressure regulator's flow characteristics at each pressure ratio. Additionally it is also introduced to examine pressure regulator's critical flow characteristics and possibility of condensation or freezing at each pressure ratio. Furthermore, the comparison between the results of CFD analysis and the results of analytic solution obtained by compressible fluid-dynamics theory is attempted to validate the results of CFD modeling in this study and to estimate the accuracy of theoretical approach at each pressure ratio too.

In this paper, the interesting moving objects tracking algorithm using color information on Multi-Video camera is proposed Moving objects are detected by using difference image method and integral projection method to background image and objects image only with hue area, after converting RGB color coordination of image which is input from multi-video camera into HSI color coordination. Hue information of the detected moving area are normalized by 24 steps from 0$^{\circ}$ to 360$^{\circ}$ It is used for the feature parameters of the moving objects that three normalization levels with the highest distribution and distance among three normalization levels after obtaining a hue distribution chart of the normalized moving objects. Moving objects identity among four cameras is distinguished with distribution of three normalization levels and distance among three normalization levels, and then the moving objects are tracked and surveilled. To examine propriety of the proposed method, four cameras are set up indoor difference places, humans are targeted for moving objects. As surveillance results of the interesting human, hue distribution chart variation of the detected Interesting human at each camera in under 10%, and it is confirmed that the interesting human is tracked and surveilled by using feature parameters at four cameras, automatically. 본 논문은 다중 비디오카메라에서 색 정보를 이용한 특정 이동물체 추적 이동물체 추적 알고리듬을 제안한다. 제안된 방법은 다중 비디오카메라로부터 입력되는 영상의 RGB 칼라 좌표계를 HSI 칼라 좌표계로 변환한 후, 영상의 색조 영역만을 가지고 배경영상과 물체가 존재하는 영상에서 차영상 기법과 가산투영 기법을 사용하여 이동물체를 검출한다. 검출된 이동물체 영역의 색조는 0도부터 360도 사이에서 24단계로 정규화 된다. 정규화된 이동물체의 색조 분포도를 구한 후, 가장 높은 분포를 갖는 3개의 정규화 레벨과 3개의 정규화 레벨 사이의 간격을 이동물체의 특징파라미터로 사용하였다. 각 카메라간의 이동물체 동일성 관별은 이동물체 특징파라미터를 가지고 판별하고, 추적 감시하였다. 제안된 방법의 타당성을 검토하기 위하여 실내에 각기 다른 장소에 4대의 카메라를 각각 설치하여 이동물체의 대상을 사람으로 놓고, 특정사람을 감시한 결과 각 카메라에서 검출된 특정사람의 색조분포도 변화는 10%내를 유지함을 보였고, 특징 파라미터로 4대의 카메라에서 특정사람이 자동 추적감시 됨을 확인하였다.

항만물류산업에서 EDI 활성화 모형개발

신창훈(Chang-Hoon Shin),김율성(Yul-Seong Kim) 한국항해항만학회 2005 한국항해항만학회지 Vol.29 No.10

중국 경제의 급성장으로 전세계 물동량이 동북아시아로 집중되어 부산항을 포함한 동북아시아 주요 항만간 경쟁이 점차 심각해지고 있다. 이에 동북아시아 항만들은 생산성과 더불어 항만의 서비스를 극대화하고자 하는 노력을 기울이고 있다. 항만이 제공하여야 할 서비스 중 가장 중요하게 부각되고 있는 항만물류정보 시스템구축 및 효율적 운영에 총력을 기울이고 있는 실정이다. 그러나 부산항의 경우, 이미 항만물류 정보시스템은 구축이 되어 있으나 EDI문서의 중복성과 시스템 연계성 부족 등의 문제점으로 인해 아직 활성화 되지 못하였다. 이에 본 연구에서는 부산항 항만물류산업에서 EDI의 활용도를 높이기 위한 전체적인 연구모형 도출과 항만물류업체를 업종별, 집단별로 구분하여 차별화된 활성화 모형을 도출하는 것을 목적으로 하고 있다. The rapid growth of economy in china leads to concentrate throughput volume of World to North East Asia. Ports in North East Asia have to cope with rapid of changes in environments. In order for a port to compete in the global market, it must provide proper productivity and promptly services of port. The system of information hold a key in port-logistic industries. Most ports make every effort to set up and operate the system of Information. Busan port already set up the system of port-logistic information such as Port-MIS, KROIS. But it is not activated yet because of problems of documentation duplication and system connectivity and so on. The purpose of this research is to make a model which can activate the system of port-logistic information. In addition, We suggest a definite and feasible model by group and types of port-logistic industry.
