도성은 왕권이 존재하는 것뿐만 아니라 왕권을 지지하는 지배계층이 모여 거주하는 곳이다. 그리고 중앙집권적 통일지배를 실현하기 위한 정치 의례의 장으로서 전근대 동아시아 세계에 공통적으로 건설되었다. 그 기원은 중국에서 유래하며, 일본은 율령제(律令制)를 바탕으로 하는 천황제 고대국가가 실현되는 7세기 말 '藤原京(후지와라쿄)'에서 처음으로 지상에 출현한다. 7세기 말부터 거의 1세기 간 복도제(複都制)가 채택되었기에 '등원경(藤原京)' 이후 도성은 여러 곳에 건설되었고, 때로는 천도되었다. 그러나 8세기 말 '長岡京(나가오카쿄)'에서는 복도제(複都制)를 지양했고, '平安京(헤이안쿄)'에 도읍을 정한 이후, 중세 근세를 거쳐 근대에 이르기까지 헤이안쿄-교토에는 1100년에 걸쳐 왕권이 지속적으로 존재하여 지금의 '京都市'(교토시)에 이르게 된다. '등원경(藤原京)'가 고대 일본 최초의 도성이었다면, '평안경(平安京)'는 마지막 도성임과 동시에 중세 도시로 변모해 가는 전환점에 위치하고 있다. '등원경(藤原京)'이래 남북축선에 대한 선대칭 구조를 의식해 도성이 축조 되었고, '평안경(平安京)'에서는 이러한 구조가 가장 강하게 표현되었지만, 9세기 초 천황과 관인들의 의식 정무의 동선이나 좌석 배치에 있어서 동서방향이 채용되게 되었고, 이에 더해 9세기 말에는 천황의 거소가 도성의 축선에서 벗어나게 된다. 또한 10세기 중반 경 '平安宮(헤이안큐)'에서는 '內裏(다이리)'를 중심으로 한 잦은 화재가 발생해 천황은 궁외로 거소를 옮기게 되었다. 이후 천황이 궁 바깥에 거주하는 것이 일반화 되었고, '평안궁(平安宮)'는 의식을 행하는 장소로서 한정적으로 유지 수리가 될 뿐이었으나 결국에는 그것마저 어려워져 폐쇄에 이르게 된다. 한편 귀족의 저택도 7세기 이래의 남북축선에 대해서 동서의 선대칭 구조로 부터, '寢殿造(신덴즈쿠리)'라고 불리는 건물배치도 공간구성도 비대칭인 건물양식이 주류를 이루어 갔다. 이상과 같이 일본의 고대 도성의 특징을 잘 가지고 있었던 최후의 도성 '평안경(平安京)'는 남북을 축선으로 하는 선대칭 구조가 가장 뚜렷하게 나타났으나, 9세기 '평안궁(平安宮)'의 변화를 시작으로 11~12세기에 크게 변모해갔다. 이처럼 고대국가의 도성이 가지고 있었던 남북을 축으로 하는 구조를 버리고 동서방향으로 동선을 취한 움직임은 고대국가의 이념을 탈피하여 다음 시대로 전환하는 중요한 한 걸음이었다고 생각된다.

A Science DeMilitarized Zone (DMZ) is an optimized network technology tailored to research data nature. The Science DMZ guarantees end-to-end network performance by forming a closed research network without redundant networking and security devices for the authorized researchers. Data Transfer Node (DTN) is an essential component for the high performance and security of the Science DMZ, since only transfer functions of research data are allowed to the DTN without any security- and performance-threatening functions such as commercial internet service. Current Science DMZ requires per-user DTN server installation which turns out a scalability limitation of the networks in terms of management overhead, entry barrier of the user, and networks-wise CAPEX. In order to relax the aforementioned scalability issues, this paper suggests a centralized DTN design where end users in a group can share the centralized DTN. We evaluate the effectiveness of the suggested sharable DTN design by comparing CAPEX against to that of current design with respect to the diverse network load and the state-of-the-art computing machine.

In order to respond to the demand for flexible operation of thermal power generation, development of natural sliding pressure operation that minimizes throttle loss by opening the turbine control valve 100% and maximize power generation efficiency in conjunction with ESS in order to quickly respond to fluctuations in the system frequency is required. The logic development of natural sliding pressure operation with ESS was developed to modify the existing logic at the power plant's top-level control logic such as the unit master, the boiler master and the turbine master. Cooperative control algorithms that complement the advantages and disadvantages of ESS operation (quick response, limited capacity) and power plant operation (slow response, continuous operation) not only improve efficiency when applied to actual power plants, but also respond quickly and flexibly to load demands to ensure system stability.

Malrotation and midgut volvulus are surgical emergencies that commonly occur within the first month of life. The classic symptom is acute bilious vomiting, while nonspecific symptoms such as recurrent abdominal pain may be present in older children. Malrotation can be associated with duodenal obstruction caused by an abnormal peritoneal fibrous band or congenital anomalies, such as an annular pancreas or a preduodenal portal vein. Volvulus can lead to bowel ischemia and a life-threatening condition, thus prompt and accurate diagnosis is crucial. Diagnosis can be made through upper gastrointestinal series, ultrasonography, and CT, with ultrasonography being preferred as a screening tool due to its rapid and accurate diagnosis, without radiation exposure, in children. This pictorial essay discusses the key imaging findings and diagnostic approaches for malrotation and midgut volvulus, as well as diagnostic pitfalls based on actual cases.

Oshii Mamoru attempts to project the perception of reality about his own modern world as it is through animation. The precedent studies on Oshii Mamoru put their focus on the point that his works have a tendency to represent the devastation of reality as the image of 'a ruin.' In addition, they gave an impression that Oshii Mamoru's animation has gradually developed to expose the 'realistic taste[beauty]' from the design perspective. However, this study is going to put its focus on the point that Mamoru's works were created as an attempt at finding the subversive possibility of the suppressed modern world under the modern capitalism in the aspect of 'everyday life' of the modern world. First, for its analytical purpose, this study intends to do that by dividing the work into the three layers such as space, body and everyday life. In Chapter II, this study, in relation with the issue of 'space' representation, analyzed the space in into the modern, mechanical, compactly capitalized space and also the space just like a closed circuit having the nature of 'repetition.' In Chapter III, this analyzed that suggests the body moving freely between a human named 'Kildren' and the inhuman from the aspect of character's body, through which Mamoru represents the capitalized, reified body of the modern world. In addition, this analyzed the extreme anxiety facing the body into the reflection of the phenomena of 'anxiety' and 'placelessness' consequent on the labor flexibility of the modern world. In Chapter IV, this study, on the basis of the analysis of layers of space & body, analyzed that the 'everyday life' of the modern world was represented in the respects of 'memory' and 'habit', and in the aspects of Mise-en-Sc$\grave{e}$ne, design and direction. In Chapter V, this rooted out the fact that Mamoru suggested the attempt at 'appropriation' based on his perception of reality about such a modern world. Such a finding includes unearthing the fact that Oshii Mamoru's work is raising a question about how to desert and appropriate the modern space. In conclusion of Chapter VI, this drew the conclusion that Oshii Mamoru's work represented the layer of 'everyday life' while dealing with the post-modern themes shown by the existing modern SF genre, provided the 'window' through which people can perceive the 'modern world radically by recommending an attempt at 'appropriation', and blazed a trail in a new realm of creation for animations.

In this study, auto-calibration method for water quality model was compared and analyzed using QUAL2Kw, which can estimate the optimum parameters through the integration of genetic algorithm and QUAL2K. The QUAL2Kw was applied to the Sum River which is greatly affected by the pollution loads of Wonju city. Two auto-calibration methods were examined: single parameter application for the whole river reach and separate parameter application for each reach of multiple reaches. The analysis about CV(RMSE) and fitness of the GA show that the separate parameter auto-calibration method is better than the single parameter method in the degree of precision. Thus the separate parameter auto-calibration method is applied to the water quality modelling of this study. The calibrated QUAL2Kw was used for the three scenarios for the water quality management of the Sum River, and the water quality impact on the river was analyzed. In scenario 1, which improve the effluent water quality of Wonju WWTP, BOD and TP concentrations of the Sum River 4-1 station which is representative one of Mid-Watershed, are decreased 17.7% and 29.1%, respectively. And immediately after joining the Wonjucheon, BOD and TP concentrations are decreased 50.4% and 40.5%, respectively. In scenario 2, Wonju water supply intake is closed and multi-regional water supply, which come from other watershed except the Sum River, is provided. The Sum River water quality in scenario 2 is slightly improved as the flow of the river is increased. Immediately after joining the Wonjucheon, BOD and TP concentrations are decreased 0.18mg/L and 0.0063mg/L, respectively. In scenario 3, the water quality management alternatives of scenario 1 and 2 are planned simultaneously, the Sum River water quality is slightly more improved than scenario 1. Water quality prediction of the three scenarios indicates that effluent water quality improvement of Wonju WWTP is the most efficient alternative in water quality management of the Sum River. Particularly the Sum River water quality immediately after joining the Wonjucheon is greatly improved. When Wonju water supply intake is closed and multi-regional water supply is provided, the Sum River water quality is slightly improved.

Purpose: We divided the children diagnosed with intususception into three different age groups and compared the clinical symptoms and treatment outcomes in order to analysis diagnosis and treatment of Intusussception. Methods: A retrospective chart review was established of 159 patients diagnosed with intussuception who had been admitted to Department of Pediatrics and General Surgery, Bundang CHA hospital from January, 2000 to May, 2004. We divided the patients into three groups, according to their age. Those who were under five months of age (group I; 21 patients), those between 5~11 months of age (group II; 61 patients), and those older than 11 months of age (group III; 77 patients). Then we compared the age, sex, seasonal distribution of occurrence, the cause, the clinical features, radiologic review, the type of intusussception, surgical methods, recurrence rate and treatment outcomes, among these three groups. Results: On comparing the clinical symptoms and signs among the three groups, the most common major clinical symptom and sign was irritabiltity in all three groups. Vomiting with irritability was statistically more common in group I (p<0.05) and bloody stool was most frequent in group III. The average time taken until a diagnosis was made after the symptom onset was, 21 hours in group I, 20 hours in group II and 22 hours in group III. Which showed no significant difference. But there was a higher rate of delayed diagnosis in group I, which took over 48 hours until the diagnosis was made (group I; 23.8%, group II; 4.9%, group III; 7.8%). Simple abdominal X-rays showed more frequent instances of intestinal obstruction in group I (p<0.05). The primary treatment done was barium enema which showed a failure rate of 52.4% in group I, 26.2% in group II and 14.3% in group III. Showing the highest failure rate in group I. Conclusion: The youngest group had vague symptoms which lead to delayed diagnosis and more frequent surgical procedures. As so, we advocate the importance of further evaluation and close observation, considering intussusception in children with symptoms of irritability and vomiting, especially in the early infant group.

Mainland China is under different conditions both socially and politically than other countries, so there is a lack of practical researches on cartoon characters. With a profound interest, the researcher has selected a character that is realistic and loved by many Chinese. The subject of the study is "Shan Mao Series." Out of 16 seasons, the most famous one is the Chronicle of Shan Mao's Wander. I analyzed the character thoroughly, dealing with the beginning of the character, the process of character development, and a reality shown in the chronicle, etc. on chapter II, and the character's image component on chapter III. Chinese modern cartoons were affected by a situational anxiety because of foreign powers and war. Thus satire cartoons went in fads among the public. The epitome of a typical cartoon was the Shan Mao Series. From 1935, when the character was first created, to now it has eaten into Chinese people's hearts. It's because the story happens during a war period and it deals with a playful, humorous main character's life and these facts show the hidden side of the unfair social system. Most of readers prefer a smart, playful, righteous, and brave character. Shan means three and mao, hair in Chinese, so Shan Mao is a child who has three hair. The character is not just a simple cartoon character; it has developed into a national figure among many Chinese. The reason why the researcher has chosen the series created by Zhang Leping, the author of the cartoon, is because a good cartoon, good animation, and even good movie stimulate the feelings that we get from our surroundings. The character which is created in China seems very unique and bizarre but there is a sense of friendliness. Also its character image and scenes make people laugh and it has become a typical symbol of a modern cartoon in China.

본 실험에서는 부력 조건이 달라질 때 단공방류구에서 정체수역으로 수평방류되는 부력제트의 거동을 규명하였다. LIF (Laser Induced Fluorescence) 시스템을 이용하여 수행하였는데, LIF 시스템은 고해상도의 이미지를 취득할 수 있어 데이터의 정확도가 높으며, 동시에 한 평면상의 농도장을 일시에 측정할 수 있는 장점이 있는 기술이다. LIF 시스템은 크게 세부분으로 구성되어 있는데 방출시스템, 포착시스템, 처리시스템이 그것이다. 실험 조건을 고려해서 온수를 이용하여 주변수와의 밀도차를 재현하였으며, LIF 시스템의 추적입자로 형광염료 Rhodamine B를 사용하였다. 또한, 실험 데이터 취득과정에서 필요한 검정과정을 수행하였는데, LIF 시스템에서 검정과정은 레이저 입사광의 강도가 불균등한 분포를 가지는 점과 주변수의 매질에 의한 근의 감쇠가 발생하는 문제를 해결하기 위한 것이다. LIF 시스템은 부력제트의 농도장을 매우 정밀하게 측정할 수 있는데, 방류밀도 Froude 수가 변함에 따라 측정된 순간이미지를 통해 제트의 진화과정을 상세하고 가시적으로 확인할 수 있었다. 검정과정을 거친 농도 종단면에서 중심선의 연장선이 LIF 시스템에 의해 측정된 순간이미지의 중심선 궤적과 거의 일치하는 것도 알 수 있었다. 또한 LIF 시스템을 통해서 취득된 단일수평부력제트의 궤적과 중심선 희석률을 기존의 상용모형인 VISJET과 CORMIX1에 의해 예측된 결과와 비교$\cdot$분석한 결과, 제트 중심선 궤적의 경우, LIF 시스템을 이용한 측정값은 대체로 VISJET 모형의 결과와 일치하는 것으로 밝혀졌다. 중심선 희석률의 경우, LIF 측정값은 대체로 CORMIX1 모형, Cederwall(1968)의 경험식과 일치하는 경향을 보였다.0\%$일 때가 밸브를 $60\%$와 $80\%$ 개폐시켰을 때보다 $0.3kg/cm^2,\;0.29kg/cm^2$ 낮게 나타나 밸브를 전체 개방 했을 때 관로내의 수압이 상수설계기준에 적합한 수압을 유지함을 알 수 있다. 상수관로 설계 기준에서는 관로내 수압을 $1.5\~4.0kg/cm^2$으로 나타내고 있는데 $6kg/cm^2$보다 과수압을 나타내는 경우가 $100\%$로 밸브를 개방하였을 때보다 $60\%,\;80\%$ 개방하였을 때가 더 빈번히 발생하고 있으므로 대상지역의 밸브 개폐는 $100\%$ 개방하는 것이 선계기준에 적합한 것으로 나타났다. 밸브 개폐에 따른 수압 변화를 모의한 결과 밸브 개폐도를 적절히 유지하여 필요수량의 확보 및 누수방지대책에 활용할 수 있을 것으로 판단된다.8R(mm)(r^2=0.84)$로 지수적으로 증가하는 경향을 나타내었다. 유거수량은 토성별로 양토를 1.0으로 기준할 때 사양토가 0.86으로 가장 작았고, 식양토 1.09, 식토 1.15로 평가되어 침투수에 비해 토성별 차이가 크게 나타났다. 이는 토성이 세립질일 수록 유거수의 저항이 작기 때문으로 생각된다. 경사에 따라서는 경사도가 증가할수록 증가하였으며 $10\% 경사일 때를 기준으로 $Ro(mm)=Ro_{10}{\times}0.797{\times}e^{-0.021s(\%)}$로 나타났다.천성 승모판 폐쇄 부전등을 초래하는 심각한 선천성 심질환이다. 그러나 진단 즉시 직접 좌관상동맥-대동맥 이식술로 수술적 교정을 해줌으로써 좋은 성적을 기대할 수 있음을 보여주었다.특히

Urban design claiming the notion of 'Sustainability', which inevitably includes ecological complexity, is normally geared towards the reflection of environmentally-friendly technical guidelines in the existing planning process. Although physical planning should be combined with economic, social, cultural, environmental issues, and policies, it is conducted conventionally as the sum of the closed sectoral approaches of planning. To overcome this limit, Design Charrette was invented for sustainable urban design or community design, which should consider the complexity of diverse issues. This design process unveils complicated and divergent problems and a variety of stakeholders participate in the integrated design simultaneously and cooperatively. Because Design Charrette must also be a process of agreement, it is used for sustainable community design. The aim of this study was to introduce Design Charrette as an alternative of Korean sustainable urban design, which is regarded as 'making guidelines related to green principles'. For such a purposes, the definition and differentiation of Design Charrette will be explained with an analysis of the introduction background, benefit and procedure. The contents, system and process of Design Charrette will be analyzed through case studies in Canada, where this method of design is widespread. In the last part, the implementation system (the comprehensive system of organization / content and direction of planning / process and output) will be deduced after concentrated analysis of one respected case, 'Sensitive Urban Infill Charrette' of the City of Surrey. This implementation system will be a crucial reference to develop Korean Design Charrette.
