TV Broadcasting is an undeniable cultural medium. TV Broadcasting Station needs a long-term perspective that suits cultural media and an aggressive cultural and artistic program development strategy that matches rapidly changing culture and technology. Of course, production staff should be composed of experts in the field as well as cultural artists. This paper is researching the promotion strategy of TV Arts programs by substituting the three keywords - the U.S., the public broadcasting station(TV) and Arts programs. And through case studies and analyses of PBS TV's "Art in the 21st Century" series, the way the public TV broadcasting station shares cultural arts with viewers is extracted. It raises the question of how the U.S. TV public broadcaster's cultural and artistic programs are different from South KOREA's. Through the above research, let's find a clue to the future direction of how the new media, now represented as Korea's blacklist, should recognize, foster, educate and strategize Fine Arts.

The abdominal tumors in children are different from those of adult. These tumors are the third most common one, preceded by leukemia and brain tumors, in children under 15 years. X-ray examination is the most important method among diagnostic approaches. The role of diagnostic imaging is to identify the precise anatomic location and extent of pathologic process with the minimal number of imaging procedures. 23 cases of abdominal tumors were reviewed in respect of age incidence, site of origin, radiologic findings. The results are briefly summarized as follows : 1. Neuroblastoma was the most common(6 cases) and wi1m's tumor(5 cases), choledocal cyst(4 cases), ovarian mass(3 cases), hydronephrosis(2 cases), were descending order in frequency. 2. The most common site was retroperitoneum(60%). Kidney was the single most common site of origin. 3. Radiologic findings. The most common findings of plain radiography was ill defined soft tissue mass and this method was helpful in the presence of calcification especially in neuroblastoma. Ultrasonographic pattern was anechoic(cystic), echoic or mixed pattern, but this method provide less precise anatomical details, nevertheless ultrasonography wes paticullary useful imaging modality for the pediatric abdominal tumors. IVP findings were renal displacement, caliceopelvic system distortion or nonvisualization of kidney, these information was helpful in determining the location of tumors. CT scan showed homogenous or inhomogenous, cystic or solid, mass with their anatomic location. 4. Ultrasonography was the most widely used specific diagnostic method, but had limited value in detecting the anatomic location of tumors. CT scan was superior to ultrasound for determining the extent of tumors.

Background: Generally, it is difficult to differentiate uterine malignant mixed M$\ddot{u}$ llerian tumor(MMMT) from endometrial carcinom in radiological and clinical aspects. Our purpose is to investigate MR findings that distinguishes MMMT from endometrial carcinoma. Materials and Methods: We retrogradely evaluated the magnetic resonance imaging findings of pathologically proven 5 cases of malignant mixed M$\ddot{u}$llerian tumor(MMMT) and 14 endometrial carcinomas to know the differential points of these two tumors originating in the endometrial cavity. The size of the mass, presence or absence of myometrial or uterine cervical invasion, growth pattern of the mass, signal intensity and degree and pattern of contrast enhancement were analyzed and compared. Results: The length of the long axis of the MMMT was 1.5-9.0cm(average, 5.7cm) but that of the endometrial carcinoma was 0.5-6.0cm(average, 2.5cm). Invasion of uterine cervix which was found in 3 MMMT cases, dilated the endometrial cavity and the lumen of the uterine cervix and showed the pattern of growing into the external os. Invasion of uterine cervix was found in only one case of endometrial carcinoma. The presence or absence of myometrial invasion, the signal intensity and homogeneity on T1- and T2-weighted images, and the degree and patterns of contrast enhancement showed no significant difference. Conclusion: Any specific finding to differentiate MMMT from endometrial carcinoma was not ascertained. However, MMMT can be suspected if the size of the endometrial mass is greater than 5cm and if the mass dilates the enocervical canal and invades the uterine cervix.

We evaluated the results of sequential SPECT dual-isotope imaging with Tl-201 and Tc-99m MIBI in 24 patients. all of whom also had coronary angiography within the past one month. Coronary angiography showed that 12 patients had no CAD, 4 patients had one-vessel CAD, 7 patients had two-vessel CAD and 1 patient had three-vessel CAD. Serial studies of resting Tl-201 and dipyridamole stress Tc-99m MIBI were completed within 2 hours. When more than 50% of coronary artery narrowing was considered significant, the overall sensitivity and specificity of CAD detection were 91.7%. The sensitivity of CAD detection in patients with one-vessel and multi-vessel diseases was 75% and 100%. respectively. Therefore, sequential dual-isotope SPECT demonstrated high sensitivity and specificity for CAD detection. In conclusion, sequential dual-isotope imaging is feasible and can be completed in a short time and may therefore enhance laboratory throughput and patient convenience.

GPS location information storage included in the HD black box is using a unique manner for each manufacturer does not have a specific standard. In this paper, in order to overcome the limitations of the storage space and thereby the image quality according to store GPS position information deteriorate to solve the problems that cause, we propose the location information concealment method included in the HDTV video content using a essential hidden region. HDTV video content is a Border Extender of 8 lines in the frame to the bottom of the compression will be required. This was inserted into the image of a gray scale used in block form in order to space the current position information is concealed to prevent image degradation. The proposed method was confirmed using real HD black box, there are more difficult to interpret the format of the ASCII code re-edit the location information when the compression effect disappears with the existing security zones added. Therefore, the proposed method is suitable for location-based services, such as Facebook or Youtube videos.

By employing in-depth interviews with a total of 14 television producers, the study seeks to investigate how the use of documentary background music has changed in the rapidly evolving media technology. This study reveals two major findings. First, the use of traditional compositional background music in TV documentary has been decreased for the last 20 years, while library music with various sound sources has been more likely to be used due to its artistic value, its digitalized formats, and its convenience. Second, the popularity of the library music use has changed the cooperative relationship between TV documentary producers and music directors, and their views on background music. Overall, compared to the past, the new media technology (e.g., much easier, faster editing process and communication through e-mails) has helped to come up with the current trend of using more library music. This trend however implies that the dependency of library music only may lose the unique value of television documentary as a work of creative art and eventually downgrade the quality of the programs. Further practical implications are discussed.

Unilateral absence of a pulmonary artery (UAPA) is a rare congenital anomaly that is frequently associated with other cardiovascular anomalies first reported by Fraentzel in 1968. Most patients who have no associated cardiac anomalies have only minor or absent symptoms. We experienced a case of isolated UAPA in a young female presenting hemoptysis. The chest radiograph showed a small left lung volume and high resolutional CT of chest showed multiple subpleural nodules and centrilobular nodules in parenchyma. The video-assisted thoracoscopic biopsy revealed diffuse dilated vessels in visceral pleura. The pulmonary angiogram confirmed the absence of the left main pulmonary artery.

본 논문에서는 MPEG2비디오 스트림에서 직접 얻을 수 있는 정보들을 활용하여 카메라의 움직임을 추정하여 이를 기반으로 하여 움직이는 객체를 추정하고자 한다. 이를 위해, 먼저 MPEG2의 움직임 벡터는 압축의 효율성 때문에 움직임의 예측이 순서적이지 못한데, 예측 프레임들의 속성을 이용하여 이를 광 플로우(Optical Flow)를 갖는 움직임 벡터(Motion Vector)로 변환하였다. 그리고 이러한 벡터들을 이용하여 카메라의 기본적인 움직임인 팬(Fan), 틸트(Tilt). 줌(Zoom) 등을 정의하였다. 이를 위하여 팬, 틸트-줌 카메라 모델의 매개변수와 같은 의미의 $\Delta$x, $\Delta$y, $\alpha$값을 정의하고자 움직임 벡터 성분의 Hough변환을 이용하여 $\Delta$x, $\Delta$y, $\alpha$값들을 구하였다. 또한 이러한 카메라 움직임(Camera Operation)은 시간적으로 연속적으로 발생하는 특징을 이용하여 각 프레임마다 구한 카메라의 움직임을 보정하였다. 마지막으로 움직이는 객체의 추정은 우선 사용자가 원하는 객체를 바운딩박스 형태로 정의한 후 카메라 움직임이 보정된 객체의 움직임 벡터를 한 GOF(Group of Pictures) 단위로 면적 기여도에 따라 누적하여 객체를 추적하고 해석하였으며 DCT 질감 정보를 이용하여 객체의 영역을 재설정 하였다. 물론 압축된 MFEG2비디오에서 얻을 수 있는 정보들은 최대 블록 단위이므로 객체의 정의도 블록단위 이상의 객체로 제한하였다. 제안된 방법은 비디오 스트림에서 직접 정보를 얻음으로써 계산속도의 향상은 물론 카메라의 움직임특성과 움직이는 객체의 추적들을 활용하여 기존의 내용기반의 검색 및 분석에도 많이 응용될 수 있다. 이러한 개발 기술들은 압축된 데이터의 검색 및 분석에 유용하게 사용되리라고 기대되며 , 특히 검색 툴이나 비디오 편집 툴 또는 교통량 감시 시스템, 혹은 무인 감시시스템 등에서 압축된 영상의 저장과 빠른 분석을 요구시 필요하리라고 기대된다.
