강선중(Kang Seon-Jung) 인천대학교 인천학연구원 2006 인천학연구 Vol.5 No.-
Among 5camps scattered in Ganghwa, Weol-got camp is planned to be restored in the future. The fundamental problem is that the names of the building and structurebuildings and subsidiary facilities in light of military affairs-which constitute the place aren’ manifest even though the camp is restored. I would make a comparative study of the pictures of ancient books and relative records, and represent materials for the right restoration of Weol-got Camp by doing various field studies under the present conditions that there aren’ extant remains of the structure. In case of Weol-got Camp, it went through the process of comparative analysis of diverse old maps. However, the contents of ‘ap of gang-wha’ owned by possession of Seoul National University, are regarded as concrete, and the restoration plan based on them is considered to be fine. Contrary to other maps, that one has marks of concrete names of the structures and constructions. In comparing the shapes of the constructions in ancient pictures with the extant remains, we see that they are mostly right although those of ancient pictures were presented relatively in brief. The contents of the study are the changes(history) of Weol-got Fort, and the construction and the scope of the camp, and the presentation of the direction for the restoration in consideration of the relationship between the fort and the camp. First, I would grasp the building activities around the domain of Weol-got Camp through the historical changes of extant Weol-got Fort and Yeon-mi pavilion, and extinct the site of hwang-heong etc, and infer the constructions in the camp and grasp their names and scope. And I would also grasp the building method and the structures(fortress wall battlement lot building site) of the fort which started to be restored and investigated for excavation recently in connection with Gang-wha exterior castle. There was Yeon-mi pavilion founded in the Go-ryeo Dynasty before Weol-got Camp lay at Weol-got district, and there was the site of hwang-heong with Yeon-mi pavilion when the camp was founded under that pavilion. Weol-got Camp was built after the formation of the camp. Therefore, the extant remains of the structures in this area are mostly facilities relative to Weol-got Fort. The names of the structures that constitute the camp weren’ recorded in documentary records, but we can know them by the old maps. Camps as national relics had official residence, inner dwelling house, servants house, warehouse, threespan gate, and fort or rest was located nearby. Similarly, in case of Weol-got Camp there were official residence, inner dwelling house, servants house, salt storehouse and storehouse as warehouses inside of the camp, and three-span gate and small gate as adjunct gate were set up. We can examine the building method of the camp and the fort one by one because the base of the fortress wall, the shape of the battlement, the supplementary building method around entrance lot, the shape of the battlement etc, were exposed in the process of investigation for excavating fortunately. These remains of the structures in the field are very essential materials for restoration operations. Jo-hae tower, Gang-wha exterior castle, water gate and weol-got should be restored with Weol-got Camp. They are considered to add a locational meaning in this area as national defense remains. And it is believed that the mid-17C when Weolgot fort was founded is the right time because setting up the time is also important in restoration operations. I repeat that the important thing in the restoration of the remains is the human historical study based on philological materials must go side by side with the engineering study of the technical approach. The sooner that study is done in the early stage of the plan, the more perfect restoration of remains is achieved with wisdom of many fields.

일측 폐색성 및 역류성 수신증에서 술전 상대적 신기능의 의미
한상원,강선중,권민중,김대중,최승강,이택,Han Sang-Won,Kang Seon-Jung,Kwon Min-Jung,Kim Dae-Joong,Choi Seung-Kang,Lee Tack 대한소아신장학회 1999 Childhood kidney diseases Vol.3 No.2
목적 : 신생아 시기에 일측성 수신증의 자연경과는 여러 요인들에 의해 변화되는데, 그중에서도 술전의 신기능은 일측 뿐 아니라 양측성 수신증의 초기 치료 지침을 세우는데 매우 중요한 의미를 가진다. 따라서 저자들은 일측성 수신증(폐색과 역류)을 가진 환아에서 환측신의 치료전과 후 상대적 신기능의 변화를 관찰하여 수신증의 예후에 미치는 영향을 관찰하고자 하였다. 방법 : 1992년 3월부터 1997년 2월까지 수술적으로 교정한 수신증 환자 393명(폐색성 108, 역류성 285)중 술후에 합병증 없이 치료가 끝나고 수술전후에 자료가 충실한 81명(폐색성 35, 역류성 46)을 대상으로 하였다. 환자들의 평균 나이는 폐색 환자에서 2.62(0.02-15)세, 역류 환자에서 3.14(0.5-15)세였으며, 평균 추적관찰 기간은 2.01(0.25-4)년이었다. 상대적 신기능은 폐색 환자에서 $^{99m}Tc-DTPA$(31명)와 $MAG_3$(4명) scan으로 술전과 술후 3개월에, 역류 환자에서는 DMSA scan(46명)으로 술전과 술후 6개월에 측정하였다. 분석은 폐색과 역류성 수신증의 두군에서 각각 술전후의 신기능 변화를 관찰하였으며, 가장 큰 영향을 미치는 인자를 찾고자 하였다. 통계는 student t-test를 사용하였고 p value는 0.05이하일 때 유의한 차이가 있는 것으로 간주하였다. 결과 : 1. 폐색성 수신증: 전체 평균적으로 수술전 37.69%(3.5-50)이었던 신기능이 수술후 40.15%(4-55)로 호전되었다. 세부적으로 살펴보면 수술전 신기능이 20에서 40%까지였던 신이 20%이하나 40%이상이었던 신에서 보다 통계적으로 의미있게 술후 신기능이 호전되었다. 2. 역류성 수신증: 전체 평균적으로 수술전 34.27%(3-49)이었던 신기능이 수술후 33.61%(3-49)로 통계적으로 의미있는 호전을 보이지 않았다. 역류에서는 술후 신기능이 통계적으로 의의있는 변화를 보이는 어떤 술전 신기능의 값도 발견할 수 없었다. 결론 : 신우요관 이행부 폐색에 의한 수신증에서는 술전 신기능이 20에서 40%사이의 신에서 신기능의 증가를 기대하고 수술을 시행할 수 있으리라 생각되지만, 실제 기준이 되는 수치에 대한 것은 더 연구가 필요하리라 생각된다. 방광요관역류에서는 술후 신기능의 증가를 보이지 않아 수술의 목적은 신기능의 증가를 위한 것보다도 술전 기능을 유지하거나 제어되지않는 요로감염등과 같은 증상의 치유를 위해 치료방법으로 선택해야 한다. Purpose: The information on the change of the relative renal function after operation is essential to set the initial treatment plan in unilateral hydronephrosis. So we analyzed the preoperative and postoperative relative renal function, and observed the functional changes by operation and reliability of the various factors in those changes. Materials and Methods: A retrospective trial was done of 81 patients, 35 ureteropelvic junction(UPJ) obstruction and 46 vesicoureteral reflux(VUR), among 393 patients undergoing operations at our institution from March. 1992 to February. 1997. The patients who had infravesical abnormalities, abnormal contralateral kidney and insufficient research data were excluded. We determined the relative renal functions using DTPA and MAG3 scan in UPJ obstruction and DMSA scan in VUR. The mean observation period after operation was 2.01(0.25-4) years. Results: A. UPJ Obstruction 1. The relative renal function was improved significantly after operation(P=0.0007). 2. The kidneys which have preoperative functions between 20% and 40% improved significantly in relative renal function comparing to the kidneys of the other functions(P=0.0046). B. VUR 1. The renal functions didn't improve significantly after operation(P>0.05). 2. There was no significant factor affecting the prognosis in renal functions. Conclusions: 1. The kidneys with UPJ Obstruction show the difference in functional improvement after operation according to the degree of the preoperative renal function, but more investigations about the exact value are needed. 2. In VUR there was no difference between preoperative and postoperative functions, the theoretical basis on objectives of the operation could be the symptoms or factors except the operation.

Three dimensional turbulent flows are numerically simulated in the inlet duct for heat recovery steam generator. The present study is aimed to analyze the effect of a variation in turbulent flow pattern by the change of roof angle in the transition duct. The finite volume based Navier-Stokes equations with unstructured grids are solved to make clear the flow dynamic phenomena. Reviews are made on with the data of path lines, velocity vectors, dynamic pressure, residuals for numerical convergence and so on. The k-epsilon, k-omega and reynolds stress are used for the generation of turbulence. Two types of roof angle are applied with and without the swirl in the duct. Turbulent flow patterns could be investigated for the optimum duct design based on the computational results.
