모바일 환경에서 컴퓨터의 성능 향상으로 멀티미디어 플레이어에 대한 사용자 요구로 하나의 동영상 재생기(Media Player)에서 여러 개의 동영상을 동시에 실행시킬 수 있는 복수 동영상 재생기가 일반화 것으로 본다. 현재로는 단일 동영상 재생에서 사용한 방법을 그대로 사용한 복수 동영상 재생을 지원하는 제품이 나왔으나, 그로 인한 문제점은 해결하지 못하고 있다. 본 논문에서는 단일 동영상 재생에서 사용되어지는 방법들을 복수 동영상의 재생 시에 적용할 경우에 생기는 문제점들 즉, 복수 동영상 재생시의 깜빡임 현상, 재생 우선순위 처리 그리고 반투명 처리 문제와 여러 개의 동영상을 재생할 경우에 가장 큰 문제점으로 공간 연출 지원이 이루어지지 않는다는 점을 인식하고, 오버랩핑(overlapping)과 오버레이 (overlay)기법을 사용하는 복수 동영상의 공간 재생기를 설계 및 구현하였다.

Poultry products including meat and eggs constitute a major protein source in the American diet and disease - causing pathogens represent major challenges to the poultry industry. More than 95 % of pathogens enter the host through the mucosal surfaces of the respiratory, digestive and reproductive tracts and over the past few decades, the two main mechanisms used to control diseases have been the use of vaccines and antibiotics. However, in the poultry industry, there are mounting concerns over the ability of current vaccines to adequately protect against emerging hyper - virulent strains of pathogens and a lack of suitable, cost effective adjuvants. Thorough investigation of the immunogenetic responses involved in host-pathogen interactions will lead to the development of new and effective strategies for improving poultry health, food safety and the economic viability of the US poultry industry. In this paper, I describe the development of immunogenomic and proteomic tools to fundamentally determine and characterize the immunological mechanisms of the avian host to economically significant mucosal pathogens such as Eimeria. Recent completion of poultry genome sequencing and the development of several tissue-specific cDNA libraries in chickens are facilitating the rapid application of functional immunogenomics in the poultry disease research. Furthermore, research involving functional genomics, immunology and bioinformatics is providing novel insights into the processes of disease and immunity to microbial pathogens at mucosal surfaces. In this presentation, a new strategy of global gene expression using avian macrophage (AMM) to characterize the multiple pathways related to the variable immune responses of the host to Eimeria is described. This functional immunogenomics approach will increase current understanding of how mucosal immunity to infectious agents operates, and how it may be enhanced to enable the rational development of new and effective strategies against coccidiosis and other mucosal pathogens.

Objective : Neuralgic amyotrophy (NA) is a distinct clinical syndrome that is characterized by the acute onset of shoulder and arm pain, weakness, and sensory loss. The purpose of this study was to assess the clinical characteristics of NA and to determine appropriate diagnostic modalities. Methods : We reviewed the medical and radiologic records of 10 patients diagnosed with NA retrospectively. Neurophysiologic studies were performed in all patients and magnetic resonance neurography was performed in the last three patients. Results : A total of 10 patients were enrolled in our study. All patients had clinical findings compatible with NA. The most common clinical presentation was severe shoulder pain and weakness in seven patients (70%). Neurophysiologic study results were abnormal in all patients. Brachial plexus magnetic resonance neurography showed that the affected brachial plexus showed a thickened and hyper-intense trunk. All patients were managed conservatively with analgesics and physical therapy. The pain and paralysis of all patients improved clinically within 6 months of the initiation of treatment. Conclusion : NA is a rare disease but the symptoms of NA can mimic those of other diseases. Neurophysiologic studies and magnetic resonance neurography are extremely useful tools for the diagnosis of NA.

톡소카라증은 생간의 섭취 혹은 개의 분변으로 오염된 토양으로부터 인간에게 감염되어 호산구 증가증을 일으키는 기생충 질환으로 뇌, 눈, 폐, 간 등 다양한 장기에 증상을 일으킬 수 있다. 호산구 침윤이 일어난 장기에 따라 간 병변을 유발하거나 장벽 비후 및 복수의 증가로 나타나는 경우가 보고된 바 있으나 전신 림프절의 증대로 나타나는 것은 극히 드물다. 전신 림프절 증대로 나타난 톡소카라증은 현재까지 약 두 개의 증례 보고가 흉부와 경부, 서혜부에서 보고된 바 있다. 하지만 전신 림프절 증대로 인해 림프종으로 오인되었던 톡소카라증은 보고된 바 없어 이러한 드문 형태로 발현된 톡소카라증에 대해 증례 보고를 하고자 한다.

As a result of trying the various manufacturing methods considering the reality of manpower and equipments with this manual, the following standardized procedures and contents can be suggested. (1) Since tools presenting Rock-Drill data must formalize the order of explanation although explainers are different, it will be valid that it is configured by existing power point method rather than by web document type. Composition of contents are selected on the basis of defence card and survey and then 8 items including initial screen, peripheral conditions, mobilization route, general conditions, use and structure by floor, department of vehicle consideration in activities and end screen are included. (2) Making methods and cautions of data included and used in power point are as follows ; - It was most effective that objects of fire fighting and location of neighboring fire fighting water were expressed by electronic map and drawing of inner building was made by scanning it after paining general architecture drawing(plan by each floor) rather than using drawing tools of EXCEL program or CAD drawing. And it was helpful to simplify contents of architecture drawing to wall, stairs and gate in understanding them. - Photographing of video data should be taken to show available fire fighting facilities in fire, use of planned space and the whole inner structure of each floor from the inside of fire fighting buildings and to display play time between 10 sec. and 1 min, for obstacles to distance from adjacent buildings or passage of special vehicles and fire fighting water from the outside of the building. - File format of video data taken in this way is most suitable to use wmv(window media video) or asf(advanced streaming format) type in consideration of time required for export, screen quality, file capacity and play type in Rock-Drill through network. - Still screen(photo) is more effective to express the department of fire fighting vehicles or other equipments than using video. (3) In configuration work of power point, hyper link was used most and configured to see any part at any situation like web document and then uniformity of presentation order of power point was complemented. (4) In case of sales facilities with the area of $35.557m^2$, the time of 22 hours and 30 minutes for five days was taken with five persons. Therefore, when eight-hour works a day were calculated, the whole process of video work for Rock-Drill can be finished with three day works.
