조영란,박상훈,김만배 강원대학교 정보통신연구소 2003 정보통신논문지 Vol.7 No.-

In this paper, we propose new stereoscopic video conversion methodology that converts two-dimensional(2-D) MPEG-4 video to stereoscopic video. In MPEG-4, each image is composed of background object and primary object. In the first step of the conversion methodology, the camera motion type is determined for stereo image generation. For this, motion vectors of background object are utilized. In the second step, the object-based stereo image generation is accomplished. The background object makes use of a current image and a delayed image for its stereo image generation. On the other hand, the primary object uses a current image and its horizontally-shifted version to avoid the possible vertical parallax that could happen. Furthermore, URFA(Uncovered Region Filling Algorithm) is applied in the uncovered region which might be created after the stereo image generation of a primary object. In our experiment, we convert MPEG-4 test video to stereoscopic video based upon our proposed methodology and analyze its results.

For the study of the effect of DNCB on hair growth of the mouse, previously sensitized with DNCB C_(57) black mice were divided into normal group, control group, 0.025% DNCB applied group, 0.05% DNCB applied group, and 0.0875% DNCB applied group. In each DNCB applied group, 0.025% DNCB solution(two times a day), 0.05% DNCB solution(one time a day) and 0.0875% NDCB solution (once on two days) were applied for the sake of applying total 350㎍ DNCB for 7 days from telogen 0 day to telogen 6th day and compared with acetone applied control group. The result were as follows; 1. In contrast to the control group, the thickness of epidermis and dermis was increased significantly (p<0.01) in DNCB applied groups. 2. In 0.0875% DNCB applied group, the thickness of epidermis was increased significantly(p<0.01) compared with other DNCB applied groups. 3. The thickness of dermis in 0.025% DNCB applied group was increased significantly(p<0.01) compared with 0.0875% DNCB applied group. 4. The number of follicles & diameter of hair of all the DNCB applied groups were greater than that of control group significantly(p<0.01). 5. The number of hair follicles of 0.025% DNCB applied group was greater than that of 0.0875% DNCB applied group significantly(p<0.01). Accordingy, it can be concluded that the hair growth will bew promoted by DNCB, and that the growth promoting effect of 0.025% DNCB applied group (two times a day) will be greater than of 0.0875% DNCB applied group (one on two day).

김혜란 ( Hye Ran Kim ),이만균 ( Man Gyoon Lee ),성순창 ( Soon Chang Sung ) 한국스포츠정책과학원(구 한국스포츠개발원) 2007 체육과학연구 Vol.18 No.4

본 연구는 크게 두 가지의 과제로 구성되어 있다. 제 1과제에서는 중년 남성 마라톤 동호인 45명과 운동습관이 없는 일반인 30명을 대상으로 체격 및 체력수준을 비교하였다. 측정항목은 신장, 체중, 신체질량지수, 체지방률, 1200m달리기, 윗몸일으키기, 팔굽혀펴기, 앉아 윗몸앞으로굽히기, 제자리멀리뛰기, 그리고 50m달리기였다. 제 2과제에서는 중년 남성 마라톤 동호인 15명과 운동습관이 없는 일반인 8명을 대상으로 최대산소섭취량, 젖산역치 수준에서의 산소섭취량, 젖산역치 수준에서의 심박수, 1초 강제 호기량, 그리고 혈액변인을 비교하였다. 두 집단의 데이터를 비교하여 분석한 결과를 요약하면 다음과 같다. 1. 마라톤 동호인과 일반인의 체격을 비교한 결과 체중, 신체질량지수, 가슴 피부두겹 두께, 복부와 대퇴 피부두겹 두께, 그리고 체지방률은 마라톤 동호인이 일반인에 비해 유의하게 낮게 나타났다. 2. 마라톤 동호인과 일반인의 체력을 비교한 결과 윗몸일으키기, 팔굽혀펴기, 앉아윗몸앞으로굽히기, 제자리멀리뛰기, 50m달리기, 그리고 1200m달리기 모두 마라톤 동호인이 일반인에 비해 유의하게 높은 것으로 나타났다. 3. 마라톤 동호인과 일반인의 호흡순환계 변인을 비교한 결과는 최대산소섭취량, 최대심박수, 그리고 VO2LT에서 유의한 차이가 나타났다. 그러나 HR(LT), FEV1.0은 유의한 차이가 나타나지 않았다. 4. 마라톤 동호인과 일반인의 대사관련 변인을 비교한 결과 TG, 그리고 HDL-C는 유의한 차이가 나타났으나, 혈중 글루코스, 인슐린, FFA, TC, 그리고 LDL-C에서는 유의한 차이가 나타나지 않았다. 이상의 결과를 종합해 볼 때, 마라톤 동호인이 일반인에 비해 높은 체력 및 건강수준을 갖고 있는 것으로 나타나 마라톤 동호회 활동이 건강 유지 및 증진, 노화의 지연에 긍정적인 효과가 있을 것으로 판단 되어 진다. 따라서 일반인들이 건강한 삶을 위해 마라톤 동호회의 활동에 적극적으로 참여하기 위한 다양한 방법이 강구되어야 할 것으로 사료된다. The purposes of the study were twofold. The first study was designed to compare physical fitness between 45 marathon club participants(MCP) and 30 general individuals(GI) who have not participated in any systematic exercise training before. Test items in the first study included the standing height, body weight, body mass index, percent body fat, 1200m run/walk, sit-up, push up, sit-and-reach, standing long jump, and 50m dash. The second study was designed to compare maximal oxygen consumption, maximal heart rate, oxygen consumption at lactate threshold(VO2LT), heart rate at lactate threshold(HR(LT)), forced expiratory volume in one second(FEV1.0), and blood variables between 15 MCP and eight GI. All data obtained in the two studies were analyzed by independent-t test and the results were as follows: 1) The body weight, body mass index, chest thickness, abdomen thickness, anterior thigh thickness, and percent body fat of MCP were significantly lower than them of GI. 2) Sit-up, push up, sit-and-reach, standing long jump, 50m dash, and 1200m run/walk of MCP were significantly superior than them of GI. 3) There were significant differenced in maximal oxygen consumption, maximal heart rate, and VO2LT between the two groups. However, there was not significant difference in HR(LT), and FEV1.0 between the two groups. 4) There were significant differences in TG, and HDL-C between the two groups, whereas no significant difference was found in blood glucose, insulin, free fatty acid, TC, and LDL-C between the two groups. The aforementioned results indicated that MCP had higher level of physical fitness than them of GI, concluding that the activities in the marathon club could enhance health and physical fitness and prevent aging. The efforts should put for the general individuals into participate sports club activities.

MPEG-21 DIA에서의 3차원 입체 영상의 적응

백운학,조영란,김만배 강원대학교 정보통신연구소 2003 정보통신논문지 Vol.7 No.-

The vision for MPEG-21 is to define a multimedia framework to enable transparent and augmented use of multimedia resources across a wide range of networks and devices used by different communities. DIA (Digital Item Adaptation) is one of main MPEG-21 parts. DIA being composed of both resource adaptation and descriptor adaptation enables digital items (multimedia resources) to be adapted to users terminal capability and preference. In this parer, we present MPEG-21 descriptions for 3D stereoscopic video conversion. Our description tools provide a functionality of description of user characteristics and terminal capabilities. In particular, the description of users display presentation preferences supports 3D stereoscopic conversion of 2D video (2D-to-3D video conversion) as well as 2D conversion of 3D stereoscopic video (3D-to-2D video conversion) so that users can view either 2D or 3D stereoscopic video they prefer. Furthermore, we investigate the effects of the type of parallax, the range of depth, and the maximum interval of a delayed frame on the perception of 3D depth. The syntax of the descriptions and their elements is represented in XML (eXtensible Markup Language) schema, and their feasibility is examined and verified in our experiments, where MPEG test sequences are adopted for 2D-to-3D video conversion. On the contrary, ordinary stereoscopic test video is used for 3D-to-2D video conversion.

MPEG-21 표준의 구현을 위한 Testbed 구축

1990년대 후반부터 다양한 디지털 통신망을 이용하여 멀티미디어 컨텐츠 서비스가 가능하게 되었다. 하지만, 멀티미디어 컨텐츠의 전달 및 이용을 위한 기반 구조들의 독자적 발전 및 다양한 통합적 관리 체계 시스템으로 인해, 멀티미디어 컨텐츠 표현 방식의 호환성 문제, 혼재하는 네트워크 전달 방식과 단말 방식의 호환성 문제 등의 잠재적인 문제점이 발생한다. 이런 문제의 대안으로 현재 존재하는 기술 및 기반 구조들 사이의 연동을 통한 큰 프레임워크인 MPEG-21이 진행 중이다. 본 논문에서는 현재 표준화 작업이 진행 중인 MPEG-21을 기반으로 하는 Testbed를 제안한다. Testbed는 server, client, DIA(Digital Item Adaptation)의 세 모듈로 구성된다. Server의 역할은 멀티미디어 컨텐츠를 Digital Item(DI)으로 생성하고, client가 DI를 요구할 경우 DIA 모듈을 통해서 변환된 DI를 client에게 제공한다. DIA 모듈은 server에서 동작되며 client로부터 요청된 DI를 분석하고 client로부터 전송된 환경 정보를 이용하여 client 환경에 적합하게 변환된(adapted) DI를 생성하는 것이 주 기능이다. Client는 server에 저장되어 있는 DI를 선택하고 user preference, terminal capability 등의 필요한 정보를 server로 전송한다. Testbed에서는 스포츠 경기의 동영상, 정지 영상, 경기 내용, 역사를 기록한 파일 등의 DI를 이용한다. 표현 언어는 XML이며, HTTP 기반의 Web 환경에서 구동되도록 설계된다.

Gastrointestinal stromal tumor (GIST) is the most common non-epithelial neoplasm arising in the gastrointestinal tract, but this tumor is rarely seen in association with type l neurofibromatosis (NFl) Generally, the majority of GISTs are isolated neoplasm and they are sporadically found in the stomach, but the GISTs in NFl patients are usually multiple and usually found in the small intestine. We report a case of multiple GISTs in the jejunum of a 63-year-old woman diagnosed as NFl accompanied by complication of gastrointestinal bleeding, In this case, Patient had multiple cafe-au lait spots and neurofibroma on skin and had freckling on axilla and groin, and then, we made a diagnosis of NFl. Gastrointestinal bleeding is controlled by resection of multiple GISTs. Generally, only 3-5% of all gastrointestinal bleeding comes from the small bowel. Causes of small intestinal bleeding are angiodysplasia, neoplasm, NSAIDs induced ulcer etc. but, If patients have NFl accompanied by complication of gastrointestinal bleeding, GISTs on small bowel must be considered.

Review : Epidemiology of Hepatocellular Carcinoma in the Asia-Pacific Region

( Ran Xu Zhu ),( Wai Kay Seto ),( Ching Lung Lai ),( Man Fung Yuen ) 대한간학회 2016 Gut and Liver Vol.10 No.3

Hepatocellular carcinoma (HCC) is the predominant primary liver cancer in many countries and is the third most common cause of cancer-related death in the Asia-Pacific region. The incidence of HCC is higher in men and in those over 40 years old. In the Asia-Pacific region, chronic hepatitis B virus and hepatitis C virus infections are the main etiological agents; in particular, chronic hepatitis B infection (CHB) is still the major cause in all Asia-Pacific countries except for Japan. Over the past two decades, the incidence of HCC has remained stable in countries in the region except for Singapore and Hong Kong, where the incidence for both sexes is currently decreasing. Chronic hepatitis C infection (CHC) is an important cause of HCC in Japan, representing 70% of HCCs. Over the past several decades, the prevalence of CHC has been increasing in many Asia-Pacific countries, including Australia, New Zealand, and India. Despite advancements in treatment, HCC is still an important health problem because of the associated substantial mortality. An effective surveillance program could offer early diagnosis and hence better treatment options. Antiviral treatment for both CHB and CHC is effective in reducing the incidence of HCC.
