The progress of data transmission technology over the Internet has spread a variety of realistic contents. The realistic contents have evolved from simple to interactive and immersive ones. One of such applcations is multi-view video requires encoders and decoders as many as the number of cameras. In this paper, to solve for these shortcomings, we propose a multi-view video system with a single encoder and a single decoder. In the encoding step, a compressed bitstream of multi-view video is generated by video mixing and compression by a single encoder. The decoding step is composed of a decoder and a scheduler controlling the decoding process. The scheduler assigns fair decoding and playback to each view sequence. The proposed method has been performed on various test sequences. Experimental results show that the proposed method is feasible to the processing of the multi-view video.

韓國의 交通行政體制에 關한 硏究

金萬培 건국대학교 1991 대학원 학술논문집 Vol.33 No.-

I studied on the organizational development of the Ministry of Transport the future. Generally speaking, The transportation administration system goal of governments typically invoke irrefutable good concepts such as mobility and the need for comprehensive, integrated, efficient, safe, equitable, environmentally-sound and energy-saving transport system. Also, Transportation administration functions and organizations very according to mode level of government. Common to all modes are function such as system planning and programming, design and construction, operations, maintenance, coordination with other modes regulation, funding and grantsmanship, and research and development. Transportation generally contributes directly about one-tenth of the value-added in most economics. Indirectly, However, its contribution is much greater since, in the extreme, virtually all of the gross national product(GNP)is dependent on transportation. Thus the improvement transportation is basic to natinal economic growth and plays a central role in the broader development procoss(involving aspects such as political and social integration as well as purely public welfare services). But, In the recent years new problems has placed on old concerns-concern with the impacts on neighborhoods air and noise pollution, and the energy-consumption characteristics of alternative transportation. In particular, Urban transport problem is provided by the seven-element, so-called, accidents, parking difficulties, traffic management, environmental impact, difficulties for pedestriants, peak hour crowding on public transport and off-peak inadequancy of public transport, and so on. There are indications that these problems have a bad situation in Korea. If the transportation administration system cannot keep up with this problems and isses in demand for transportation in Korea, It risks becoming a drag or a bottleneck to national development and everyone's life. Therefore, the purpose of this treatise is to shed some light on social isses or dilemmas in transportation administration system in korea, especially point out the dispersion of this relation system, then not cope with the situation of transportation. The definition of the transportation administration system can be the maximization of transportation supply capability and control the minimization dysfunction. From this point of view, the flexibility of response of the transportation organization system must be preserved so as to avoid economic demage caused by unnessary or inappropriate cutback in transport operation or development in an effect to reorganize the ministry of transport in korea. In conclusion, I proposed that the improvement of the Korea's transportation organization system reorganize as soon as possible to assure the coordinated, effective administration of transportation programs, to facilitate the development and improvement of coordinated transportation service, to develop national transportation policies and programs conducive to the provision of fast, safe, efficient and convienient transportation, to stimulate technological advances, research and inevitablely development in transportation, and inevitablely considerate "continuing, comprehensive, coordinated", socalled "3C", planning in transportation planning process, and to develop the nationed transportation policies and programs to accomplish those objectives with full and appropriate consideration of the needs of the public, users, carries, industry, labor, and the national economic development.

지방산화 촉진인자인 활성산소종 (Hydrogen peroxide, Superoxide, Hydroxyl radical)과 Iron sources 들이 고혈압 치료제로 사용되고 있는 한약재료추출물들과의 반응효과를 in vitro 상에서 검토한 결과 oil emulsion 상태에서 활성산소종은 OH, H₂O₂, KO₂ 순으로 지방산화 촉진작용이 나타났으며, 한약재료추출물 자체도 산화반응을 어느정도 촉진시키는 경향이었다. 한약재료추출물의 활성산소 포집능은 KO₂에 비해 H₂O₂와 OH은 나타내지 않는 경향이었다. 그러나, 전반적으로 지방산화를 촉진시키는 ?? ion binding 능력은 추출물 모두 탁월하였다. ?? ion의 함량은 도인, 솔잎에 비해 단삼, 당귀미가 높은 수치를 나타내었으며, total iron 함량 역시 같은 경향이었다. 항산화작용을 하는 ascorbic acid 함량은 솔잎이 26.97ppm으로 가장 높은 함량을 나타내었으며, 단삼과 당귀미는 19.74, 22.14ppm으로 유사하며, 도인이 5.50ppm으로 낮은 값을 나타내었다.(P<0.05). 전자공여능은 솔잎, 단삼이 각각 79.54%,77.11%로 도인, 당귀미보다 높게 나타났고, SOD 유사활성측정에서는 도인이 0.16으로 가장 낮은 흡광도 수치를 나타내어, pyrogallol의 자동산화를 억제하는 SOD 유사활성이 다른 추출물에 비해 높은 것으로 나타났다(P<0.05). 아질산염소거작용은 pH에 따라 소거능이 다르게 나타났으며, 솔잎과 당귀미가 pH 1.2에서 각각 99.8%, 98.6%의 강한 소거능을 나타내었고, pH의 증가에 따라 전반적으로 감소하는 경향이었으며, 특히, pH6.0에서는 단삼과 도인의 경우 아질산염 소거작용이 나타나지 않았다. 이상의 결과로 한약재료 추출물 4종의 기능성은 솔잎 추출물이 가장 우수한 것으로 사료된다. This study was carried out to investigate the effects of herb extracts on lipid oxidation and free radical reaction in iron sources reacted with active oxygen species. The results were summarized as follow; The catalytic effects of active oxygen on lipid oxidation in oil emulsion tended to be showed OH, H₂O₂ and KO₂ in order. At the same time, herb extracts itself were tended to be showed a little catalytic effects. Active oxygen scavenging ability of herb extracts didn't show, but herb extracts played role as a strong chelating agents to bind iron ion if ?? ion exist in oil emulsion. The content of ?? ion Salvia miltiorrhiza Bge, and also, the content of total iron was the same persica Stokes and Pinus strobus. And also, the content of total iron was the same tendancy. The content of ascorbic acid of Pinus strobus showed the highest amounts as 26.97ppm among all herb extracts, but Salvia miltiorrhiza Bge., Angelica gigas Nakai and Prunus persica Stokes were 19.74ppm, 22.14ppm and 5.50ppm, respectively(P<0.05). Electron donating ability of Pinus strobus and Salvia miltiorrhiza Bge. were 79.54% and 77.11%, respectively, which was showed higher content than those of Prunus persica Stokes and Angelica gigas Nakai. The SOD-like activity of Prunus persica Stokes was showed optical density(O.D.) 0.16, compared to other berb extracts which means the most strong antioxidant reaction. The nitrite scavenging effects were tended to be different, depending on pH value as pH value was increased. They were decreased overall. Especially, they didn't show the nitrite scavenging effect in pH 6.0. In conculsion, the Pinus strobus extract among herb extracts were the most effective by evaluation as functional sources.

To study the relations of underground/surface-water exhaustion and excessive pumping, we have analyzed river, geological characteristics, recharge rate of rainfall and underground-water level. The ground water recharge rate from the SCS-CN analysis is 8.4%, and the recharge is computed in 6.4111 x 10^(5)㎥/y. This results mean that a big drawdown in observation holes may be occurred by excessive pumping. From in-situ hydraulic conductivity test, hydraulic conductivity in basement of the study area is calculated in 7.996 x 10^(-6)-2.067 x 10^(-6)m/sec. The underground/surface-water in the study area with small underground-water recharge rate will be exhausted by long time pumping.
