  • The government is in progress the traditional retail market redevelopment and remodeling due to atrophy of the traditional retail market in accordant to opening of the circulation market and changing of the consuming patterns. However, it seemed that primitive project was limited to the environment improvement scope. As the shopping environment which is comfortable to the consumers is provided and the design which considers a traditional retail market specific quality is applied from business plan early. It will be useful for the management normalization of traditional retail market actually. The spatial factors were analyzed as follows. 1. The circulation of consumer should be secured to make boundary line of the pass way. 2. The display booth should be standardized for the security of sight. 3. The signage panel should be consolidated in according to the plan. 4. The street vendor's handcart and tent should be arranged for circulations and the vision line.

  • The authors have performed operations on vascular system of 108 cases from 1972 through 1979, and analyzed the diseases, surgical procedures and results. They were 1. Arterial system; 45 cases P.D.A. : 20 Occlusive diseases : 13 Coarctation of aorta : 4 Aneurysm : 4 A-V fistula : 2 Trauma : 2 2. Venous system; 6 cases Esophageal varix : 4 S.V.C. syndrome : 1 Varicose vein : 1 3. Arteriovenous shunt for hemodialysis; 57 cases Of the arterial diseases, the worst results came from Burger`s disease. For the bleeding esophageal varices, we have performed ligations of varices or collateral circulations rather than emergency splenorenal shunt with good results. External A-V shunt for hemodialysis had much more complications than the A-V fistula.

  • This project has been designed for people to experience and understand the process, importance and benefit of coal fire plants. As the biggest and first typical Korean fire plant using coal, Boryeong fire plant has had important roll for the Korean industries. Even so, people has had wrong prejudice for the fire plant in terms of environmental protection. To do these kind of rolls, this museum has been designed with theme, "Boryeong fire plant mating symbiotic relationship between nature, human and technologies." The space was zoned with five major themes: i. circulation of energy in nature, ii. electric power and eco-fire plant, iii. future energy, iv roll for future of environment, v. Korea as the leading energy industry. The design has been developed focused on spatial experiences to make 'Design Sequence' with linear circulations haying several important destinations. The interior has been finished with minimal color and materials projected by big sized movie and various LED movie system. Concept of appordance has been used to make interactive experiences between exhibits and visitors.

  • The purpose of this study is to find the variation of sedimentation patterns after Saemangeum reclamation. Residual flow after Saemangeum reclamation was calculated prognostically from the observed water temperature and salinity data in May 1992 by the Marine Development Institute of Gunsan National University and wind data which were obtained from spring 1969 through winter 1977 by the Kunsan Meteorological Observatory. Three dimensional movements of injected particles due to currents, turbulence and sinking velocity are tracked by the Euler-Lagrange method. When suspended sediments with the size of soil grain of 30 ㎛ are injected in the Sinsi drainage sluice, their dispersion range of sediment is around Gogunsan islands. When suspended sediments with the size of soil grain of 200 ㎛ are injected in the Garyeok drainage sluice, their dispersion range of sediment was around the Garyeok drainage sluice and Byeonsan coastal area.

  • Objectives : The paper seeks to provide a study on Bianque's Pulse Diagnosis in the contexts of Huangdi Neijing's Maijing and Nanjing. Methods : The paper provides a comparison of sentences regarding Bianque's Pulse Diagnosis discovered in Neijing, Maijing, and Nanjing. Results & Conclusions: 1. Bianque's Pulse Diagnosis was given birth through stages in accoradnce with the development of Pyobonjin, Maeggujin, Gyeongmaeghyjin, and Meridian Theory. 2. It seems that Neijing filled in Sambuguhujin and In-yeongbuyangmaegjin because they were not discovered in Canggong's Records of Diagnosis. 3. Bianque's Pulse Diagnosis diagnosed death using Osaegjin. Underneath each sentence within each biography regarding Meridian, there existed Pulse dead Hou. 4. Bianque's Pulse Diagnosis quantified the operation and length of pulse in time. The concept of small net was added which led to the establishment of Fifty circulations, Yeongwi theory, Meridians circulation, and chongu's boundary.

  • The complexity of the papermaking system accelerates interactions between a large number of variables involved. The process operation, therefore, is subject to frequent perturbations by disturbance. Dynamic modelling is a useful tool for characterizing the transient behavior and selecting the best control strategies to reject disturbances. In this study we developed a dynamic simulation model of a fine paper production process, which consists of stock preparation, wire sections, white water circulations, and broke system. It focused on dynamic simulation in its role for developing control strategies and studying control loop dynamics related to filler loading for ash control. The results emphasized the importance of filler-loading position and length of control loop for rapid ash control and process stabilization.

  • This is a report of a. case in which a long narrow segment coarctation of the aorta was successfully corrected with Teflon graft. The patient was 30 year old man with hypertensive symptoms that occurred 7 years prior to operation. Blood pressure measured 230/110 mmHg in the arms and 110/80 mmHg in the legs. Pulses were strongly tensive in radial artery, but very weak in femoral artery and even absent in dorsal pedis artery. Final preoperative diagnosis was made by aortography which showed a long narrow segment between aortic arch and descending thoracic aorta and highly developed collateral circulations. A long hypoplastic narrow segment was located proximal to the ligament arteriosus, and diaphragmatic stenosis of the aorta was located just distal to the ligamentum arteriosus. After prosthetic correction of the coarctation of the aorta, blood pressure were measured 130/ 80 mmHg in the arms and 150/100 mmHg in the legs. Peripheral pulses were palpated normally, and the postoperative course was uneventful.

  • Transposition of the great arteries is one of the commonest forms of severe congenital heart disease and produces severe cyanosis threatening survival from the day of birth. Anatomical anomalies which the aorta arises from the infundibulum of the right ventricle and the pulmonary artery arises from the outflow tract of the left ventricle make the deranged circulation. Survival is possible only if additional anomalies are present which allow mixing of the pulmonary and systemic circulations. Preoperative diagnosis as TGA was taken on the 15 day old female via the preoperative examination and the right cordioangiography. As palliative treatment for cyanosis, Blalock-Hanlon operation was performed in this patient. The results were good as 54 mmHg changed from 27 mmHg of $PO_2$ in aorta, but sudden cardiac arrest was developed in postoperative 12 hours. In order to confirm the cause of death and the cardiac anomalies, autopsy was performed on the date of death. The diagnosis of the autopsy showed; [1] Transposition of the Great Arteries. [2] Patent Ductus Arteriosus. [3] Patent Foramen Ovale. [4] Ventricular Septal Defect, 2 Muscular Type. [5] Double Ureter, Right. [6] Artificial Atrial Septal Defect. [7] Total Collapse of the left lung and Intraparenchymal hemorrhage of right lung.

  • The CHF phenomenon has been investigated for water flow under forced and natural circulation modes with vertical round tubes at low pressure and low flow condition. Experiments have been performed by using three different test sections for mass fluxes below 400 kg/㎡s under near atmospheric pressure. The experimental data for forced and natural circulation are compared with each other. To predict the flow rate at the two-phase region our test condition has been analyzed by RELAP5/MOD3 because the local two-phase condition inside the stainless steel tube cannot be directly measured. To predict the CHF with accuracy we have to consider the parameters at the single-phase region as well as the flow behavior at the two-phase region.

  • 본 연구는 대전 지역에 소재하고 있는 15개 공공도서관을 대상으로 DEA 모형을 사용하여 2008년도 공공도서관의 상대적 효율성을 분석하고 이어서 최근 3년간의 추세변화를 분석하였다. 투입요소로는 직원수, 면적, 장서수가 사용되었으며 산출요소로는 이용책수와 이용자수가 사용되었다. 연구결과, 기술효율성 값의 추세변화를 분석해 보면 3년간 지속적으로 효율성이 개선되었으며, 기술효율성의 개선은 순수 기술효율성과 규모 효율성 둘 다의 개선에 있었다.
