미디어아트는 20세기 중반이후 기술 발전과 컴퓨터의 등장으로 빠르게 발전하고 있다. 1960년대에는 "사운드아트"의 개념이 등장하면서 노이즈를 비롯한 다양한 사운드의 활용가능성이 부각되어 왔다. 영화, 설치예술 등의 작품에서 이미지와 사운드는 상호보완적으로 다양한 형태로 결합한다. 이 중 미디어 퍼포먼스는 사운드와 비주얼의 결합양상 중 전시형태를 벗어나 공연으로서의 사운드 비주얼리제이션을 추구하며 현장성과 즉흥성이 특징이다, 도시 건물 외벽의 커다란 스크린을 활용한 미디어파사드는 오늘날 산업체의 광고 뿐 아니라 미디어아트분야에서도 활발히 활용되고 있다. 본 연구에서는 이러한 연장선상에서 사운드아트의 유형을 분류하고, 박순영 이수진의 "Ta!(打-他) for realtime audio and video"를 사운드 비주얼리제이션의 공간적 확장을 통한 미디어 퍼포먼스 측면에서 분석 연구한다. Media art has rapidly developed through the technical development and the introduction of digital technology since mid-twentieth century. In 1960s, the notion of sound art emerged with the various methods of sound utilizing noise. Sound and image mingles together in various forms of art such as films and installations. Among them we focus on media performance which searches for sound visualization as a performance beyond the exhibition style, having on-site and improvisational features. Media facades use big screens in the outside of the buildings and are used not only for advertisements but also for live public media art thesedays. In this regards, we classifies sound arts into four categories and introduce"Ta!(打-他) for realtime audio and video" by Soon-young Park and Suzin Rhee, as an example for latest forms of sound arts which is a media performance through the spatial expansion of the sound visualization.

The economic impact on the environment and human health caused by conventional chemical intensive agriculture is causing scientist to re-assess the development of agricultural systems. Pesticides and processed chemical fertilizers have been shown to becausing environmental disruption which will nudermine the resource base on which agriculture production depends. The rise of sustainale agriculture, integrated pest management, organic agriculture, and other forms of alternative agriculture are a result of varmers and researchers searching for new solutions to the problem of food production which does not endanger the all important agriculture are a result of farmers and researchers endanger the all important agriculture resource base. Organic agriculture is one approach which has been developing more quickly in recent years with increasing consumer purchasing power. Organic agriculture has shown itself to be sa or more profitable, and in many cases as productive as conventional agricultural methods on some crops. Further development of organic agriculture, and low-input agriculture will require further modification of policies which overwhelmingly support high imput, chemical intensive agriculture.

Mixed hardware and software implementation is common in the design of digital systems such as communication systems, DSP applications, and embedded control systems. In general, software is easy to modify, maintain, and upgrade, though it is slow compared to hardware. On the other hand, hardware can be made faster than software but the cost for all hardware solution is usually too high. A design issue raised in designing such systems is to find the point in between all hardware solution and all software solution to improve the performance as much as possible at a minimum hardware cost. The hardware software codesign methodology enables us to design mixed hardware and software systems with optimum performance and cost. There are several different style of codesign, depending on what assumptions are made about the specification and the components and what elements of the system are synthesized. We introduced hardware software partitioning, which map a behavioral specification onto a hardware architecture consisting of a CPU and multiple ASICs. In this paper, we propose a partitioning algorithm for hardware software codesign. The new algorithm exploits the urgency that resides in the system to improve the performance maximally at a minimum hardware cost with low complexity of partitioning algorithm. The key of the new algorithm is the concept of node's probability that can run in parallel with each other candidate node in both hardware software distribution graph but, it may hardly be delayed. We calculate the cost function and select the node with max value and because, we can get low cost system and satisfy the constraints with low algorithm complexity. At present, this algorithm is incomplete. To obtain better results, it is necessary to introduce a communication model between hardware and software part, variety of Basic Scheduling Block's size, and so on.

Embedded systems typically consist of application specific hardware parts and programmable parts,i.e processors like DSPs, core processors or ASIPs. In comparison to the hardware parts, the software parts can be developed and modified each easier. Thus software is less expensive in terms of costs and development time. Hardware however, provides better performance. For this reason, a system designer's goal is a system which fulfills all performance constraints by using as few as possible hardware. Hardware/Software codesign deals with the problem of designing embedded systems. This paper describe an improved approach in hardware/software partitioning. The approach is based on backtracking method to solve the partitioning problem. Because our algorithm use dynamic search order, pruning function, this algorithm will be more faster than simulated annealing for finding optimal partitioning.

무화과의 암면 양액재배를 통하여 시설재배의 가능성을 검토하고 배지종류 및 품종에 따른 과실생육 및 수량을 검토하여 우리나라 기후에 가장 알맞는 품종을 선발하고 육성을 도모하기 위하여 수행하였다. 봉래시 품종을 4종류의 배지(펄라이트, 코코피트, 암면슬라브 및 입상암면)에 재식하고, 또한 '마쓰이도후인', '봉래시', '화이트제노아' 및 '브라운터어키' 품종을 본엽 4∼5매인 5월 17일에 암면슬라브에 각각 15주씩 정식하여 생장반응과 총수량 등을 조사한바 배지종류에 따른 봉래시 품종의 생장반응은 암면과 입상암면 배지에서 초장, 엽수, 엽장 및 측지수가 다른 배지보다 높게 나타나 이들 두가지 배지의 이용 가능성이 컸고, 암면을 사용하여 재배한 경우 초기 생장은 봉래시 품종이 좋았으나 과실의 수량면에서 단위면적당 총수량과 주당 평균수량은 마쓰이도후인>브라운터어키>봉래시, 화이트제노아 순으로 많았고, 과실 한개당 평균무게, 과장 및 과폭은 브라운터어키 품종이 가장 높았다. 우리나라 남부지역에서 시설내 양액재배에 가장 적당한 품종은 마쓰이도후인 품종과 브라운터어키 품종으로 추천되었다. This experiment was carried out to know the effect of cultivars and substrates on the growth and development of fig tree (Ficus carica L.) grown in hydroponics. Four cultivars ; Masui Dauphine, Bongraeshi, White Genoa and Brown Turkey, were used and four substrates, perlite, cocopeat, rockwool and granular rockwool were employed. Every cultivars cutted into 20cm with two buds on 27th, of February and then inserted into fockwool cube for root initiation, Every fifteen cuttings were transplanted on 17th of May in each substrate. Among cultivars 'Bongraeshi' showed highest growth in terms of plant height, number of leaves and shoots, and leaf length in the both rockwool and granular rockwool. Total yields per square meter and average yields per plant were higher in the order of Masui Dauphine > Brown Turkey > Bongraesh and White Genoa. Brown Turkey showed the heavier frjuit weight and larger fruit length and width than those of the other cultivars. Consequently, optimum cultivars and substradtes for hydroponics were recommended as Masui Dauphine and Brown Turkey, and rockwool and granular rockwool. However further trials would be followed as to the nutrient concentration, composition and solution managemint for improving fruit yield and quality of fig tree during growing period.

삼일열 말라리아는 국내에서 재유행하고 있는 감염질환으로, 일반적으로 양성의 임상경과를 거친다. 저자들은 특이한 질병력이 없이 건강하였던 젊은 성인이 국내에서 삼일열 말라리아에 걸린 후 다기관기능부전과 폐출혈으로 사망한 증례를 경험하였다. 환자의 중증 임상경과를 설명할 만한 특이한 인자가 발견되지 않았다. Vivax malaria is a re-emerging infectious disease in Korea with cumulating 19,416 cases as of December 2003 since 1993. Vivax malaria is generally a benign disease with few severe complications. Even in the worldwide literature, there are only small number of case reports on severe complications. We experienced a fatal vivax malaria in a previously healthy young adult with severe multi-organ failure and fatal massive pulmonary hemorrhage. The patient presented with abdominal pain and shock. There were splenic hemorrhage, disseminated intravascular coagulation, oliguric acute renal failure requiring dialysis, and pulmonary hemorrhage leading the patient finally to death. The initial parasitemia was 2,046/μL. Thin smear and PCR revealed only Plasmodium Vivax. There was no explainable cause of death except for the only serological suggestion of Mycoplasma pneumoniae infection without correlating clinical evidence. This is a first case of fatal vivax malaria in Korea since its re-emergence in 1993. Further case monitoring is needed to define whether this is a index case or an isolated one.

Superior mesenteric artery (SMA) syndrome is a rare entity characterized by external compression of the third portion of the duodenum by the SMA, resulting in proximal duodenal obstruction. SMA syndrome is manifesting with nausea, anorexia, epigastric pain, bilious vomiting, and postprandial discomfort severe weight loss in catabolic states, external and intra-abdominal compression, mesenteric tension or postoperative states can lead to SMA syndrome. A 36-year-old man developed sudden-onset epigastric pain, bilious vomiting. He was diagnosed with hyperthyroidism 8 months ago and he was treated with antithyroid drugs for 6 months, but he stopped taking the medicine 2 months ago. Abdominal computed tomography revealed typical findings of SMA syndrome. His symptoms subsided shortly after treatment of hyperthyroidism including antithyroid drugs, beta blocker therapy. Then he took radio-iodine treatment. He has taken synthyroid as hypothyroidism after radio-iodine therapy and maintained euthyroid state.

The backside gettering phenomena of OSFs which are generated at the Si-SiO₂interface during the oxidation is observed. After the backside boron diffusion at 1200℃ for 120min, the OSFs' density on the Si(100) front surface is reduced from 10?cm-²to about 20cm-²or below. In addition to, the rate of decrease of the OSFs' density is deduced experimentally as a function of the boron diffusion time and temperature.
