서천읍성 축조 이전의 서천군 치소

서정석(Jeong Seog Seo) 충청남도역사문화연구원 2022 충청학과 충청문화 Vol.33 No.1

여말 선초에 평지의 읍성이 출현한 것은 다 아는 사실이다. 다만 그러한 평지의 읍성이 출현하기 이전에 각 군현(郡縣)의 치소성이 어떠한형태로 있었는지가 관건이다. 여기에 대해서는 크게 두 견해가 있다. 하나는 나지막한 구릉이나 산봉 위에 산성의 형태로 있었다는 견해고, 다른 하나는 성벽만 축조하지 않았을 뿐 여말 선초의 읍성과 같이 평지에자리하고 있었다는 견해다. 서천읍성이 현재의 자리에 축조된 것은 조선 세종 때다. 그렇다면 세종 때 서천읍성이 축조되기 이전의 서천군 치소는 어디에 있었을까. 이에 대해서 신증동국여지승람에는 영취산(靈鷲山) 정상부에 고읍성(古邑城)이 있다고 되어 있다. 실제로 영취산 정상부에는 현재 남산성(南山城)이 자리하고 있다. 따라서 이 남산성이 서천읍성이 축조되기이전의 서천군 치소성(治所城)으로 비정된다. 다만, 산성이 자리한 산봉(山峰)은 해발 140m에 이르는 만큼 치소를 구성하던 관아시설은 남산기슭에 자리하고, 남산성 안에는 창고시설만이 자리하고 있었던 것이아닌가 한다. Eupseong(邑城) was appeared to be Late Goryo and Early Chosun. Butwe don’t know Gunhyeon(郡縣)’s Chisoseong(治所城) that appeared previuos flatland Eupseong(邑城). We have tow opinion about it. One is sanseong that is a hill or a peak. The other is flatland that is Eupseong late Goryo and Early Chosun. Seocheoneupseong was constructed in Sejong. Where is located in Seo-cheongun Chiso previous Seocheoneupseong. Seocheongun Goeupseong was located in peak of Yungchuisan in Seocheon. The present there is Nam-sanseong(南山城) locate in Yungchuisan. So we are guessing Seocheongun Goeupseong is Namsanseong. But we are guessing government office is not in it. Only Seocheongun warehouse was located in there.

High capacity optical transmission and network system in these days are mainly based on WDM(Wavelength Division Multiplexing) technologies. Photonic switching that cope with these high capacity WDM signals also should be operated in WDM domain. Therefore, optical buffer that are indispensible for photonic switching have to be a WDM structure. In this paper, we discuss various WDM optical buffers in terms of their structure, function, and specific features. More over, we introduce novel ultra high capacity WDM output buffer and WDM output shared buffer with analysis.

This paper deals with the flexural behaviors and design method of R.C beams strengthened by carbon fiber sheets. The behaviors of strengthened beams which were preloaded are compared with that of a beam which was not preloaded. The structural behaviors of strengthened beams are compared with flexural theory and current codes. According to the results, it is shown that strengthening of damaged beams is structurally efficient and that the strength of the strengthened beams are improved. The composite action between concrete and CFS are preserved after strengthening regardness of preloading. And, it is shown that the behavior of strengthened beams follow simple laws of mechanics and can be predicted by codes.

This study is aimed to identify the property and condition of the bond of mortar in accordance with the kind of surface by extracting the optional mixing of mortar and the ratio of water to cement in the execution of spray coat work. The conclusion was summarized as follow. In case the ratio of water to cement mortar is 45 percent, its good strength of bond can not be expected as the workability required of the execution of spray coat works is not assured. In case of the mortar with the ratio of cement to sand of 1:2, the higher the ratio of water to cement becomes, the lower the strength of its bond becomes. But, in case that the ratio of cement to sand is 1 to 3, the higher the ratio of water to cement becomes, the stronger the strength of its bond becomes. The bond strength of spray-coated mortar in accordance with kind of surface materials was shown to be in orders of the cement brick surface. concrete surface using plywood form, and concrete surface using steel form.

The purpose of this study is to present data on the optimum planning and construction of aluminum curtain wall to apply high-rise buildings for improving planning and construction by performance test of aluminum curtain wall. From the results of study, the conclusion can be summarized follow. Air leakage can be diminished 3.5∼4 times in quantity and leak of water can be prevented by sticking the mullion and the silling part of sash with adhesive tape and vinyl. The leak of water through weep whole can be prevented by making the first seal and secondary membrane sheet on the contacting part of aluminum and other materials, planning the hole to cross each other in case of flowing backward of water by wind. It id identified as increasing structural steadiness by reforming projection window hand strike, reinforcing mullion fastener, reinforcing heat-treated mullion aluminum sash heat, and reinforcing bolt and nut of mullion and fastener by welding.

This paper deals with the flexural behaviors and design method of R.C beams strengthened by steel plates. The behaviors of strengthened beams which were preloaded are compared with that of a beam which was not. The structural behaviors of strengthened beams are compared with codes of strength design method. According to the results, it is shown that strengthening of damaged beams is structurally efficient and that the performance of stiffness and strength of the strengthened beams are improved. The composite action between concrete and steel plates are preserved. And it is shown that the behavior of strengthened beams follow simple laws of mechanics and can be predicted by codes on strength design method.

Background and Objectives: Two hundred cases of the open heart surgery due to congenital and acquired heart disease were done using the cardiopulmonary bypass in the Department of Thoracic and Cardiovascular surgery, Chosun University Hospital from November, 1980 to June, 2001. Material and Methods: The number of congenital heart disease was 132 cases. 68 cases were acquired heart disease. 'The age of the congenital heart disease was from 22 days to 45 years. In the acquired heart disease, the age was from 14 to 72 years. Result: Congenital heart disease consisted of 113 congenital acyanotic heart disease, 19 congenital cyanotic heart disease. Corrective operation was done for congenital heart disease with 4. 5 % operative mortality. Of 68 cases acquired heart disease, 44 patients were valvular heart disease, 3 cardiac tumors, 9 ischemic heart diseases, 12 aortic dissections and etc. The operative mortality was 13%. Conclusion: The postoperative complications were appeared in 68 cases and the complications were wound infection, occipital alopecia, low cardiac output syndrome, arrhythmia, septicemia etc. The mortality after open heart surgery was 15 cases and the causes of death were low cardiac output syndrome, septicemia, respiratory failure and left ventricle rupture.

Pulmonary blastoma is a very rare primary neoplasm of the lung. We experienced a case of pulmonary blastoma in a 40 years old man. The mediobasal segmentectomy of the right lower lobe was performed. The patient was discharge on the postoperative days 6. There is no evidence of recurrence or metastasis on followup study during 7 months period after operation.

Background: Diaphragmatic rupture may occur from blunt or penetrating thoracoabdominal trauma, which may be undiagnosed initially in the acute trauma, work-up and may remain unrecognized. Delayed traumatic diaphragmatic rupture is reported with increasing frequency and is associated with high morbidity and mortality. The purpose of this study was to present our experience and found out early diagnostic method, clinical presentation and management. Matehals and Methods: From March 1998 to February 2004, the 6 patients of delayed diaphragmatic rupture in our hospital were operated. We reviewed the diagnostic interval, symptom, diagnostic method, operative method and complication. Resutt: They were 3 men and 3 women. Mean age was 56.8:t15.8 years(range 29-69). Most common symptom was dyspnea. Delayed diaphragmatic rupture was right-sided in 4 patients, left-sided in 2. The average operative interval of delayed diaphragmatic rupture was 18.8 months(range 5-48). The diagnosis was chest x-ray and thoracic CT. Operative approach were only thorax in 4 patients and both thorax and abdomen in 2. Postoperative complication were observed in 4 patients, and the overall mortality was none. Conclusion: The delayed case of traumatic diaphragmatic rupture tends to be overlooked without suspicion, In all patients with thoracoabdominal blunt injury a rupture of the diaphragm must be suspected. With a high suspicion, a thorough physical examination and diagnostic method is recommended in order to avoid early or late complications.
