This research was carried out about the Bansu which surrounded the Sunggyungwan(成均館), national university in the Joseon Dynasty to get the main characteristics of the landscape at Korean traditional school campus by analyzing cultural meaning and historical origin. The earliest record about the Bansu was in "The Book of Odes(詩經)" as Bansu was the water flowing near the Ban palace(泮宮). But, in the following time, Bansu has become the symbol of the school which was built by the feudal lords and one of very important elements in the temple-school(廟學) landscape. The Bansu of Sunggyungwan at Joseon Dynasty was the streams flowing at the east and west of the school campus and get together at the south. Sunggyungwan was located in the sacred place which followed the special organization of Bansu at the beginning of the Joseon Dynasty. And, Bansu in Joseon Dynasty was influenced by the Bansu in Song Dynasty(宋), but it was different from the Bansu in Ming and Qing Dynasty which has been formulated as the halfround pond in front of the school. This research tried to find the reason why in the Josenon Dynasty the stream flowing around the school was regarded as the Bansu. Bansu was also regarded as an important element in the public school, Hyanggyo(鄕校) and the private Seowon(書院). According to this research, the streams which flows around the Seowon or the Hyanggyo were found as called Bansu. Water stream around the Hyanggyo and the Seowon in the Joseon Dynasty has to be reconsidered under the deep research on the organization of Ban-su.

This research was carried out to investigate the history and development process of the Bansu(泮水) which appeared uniquely at the Chinese 'temple-school(廟學)', Confucian schools as the common and necessary facility through the literature reviews and field surveys. The earliest record about the Bansu was shown in "The Book of Odes(詩經)". Originally Bansu was the water system which flowed near the 'Banpalace(泮宮)', but, in the following time, Bansu has become the symbol of the school which was built by the feudal lords and a very important element in the temple-school landscape. Temple-schools were started at Song(宋) Dynasty and at that time there was no certain form of Bansu, just the natural water course near the structure. Until Ming Dynasty, the "Picture of the Feudal lords' Ban-su" in the book "Samjedohoe(三才圖會)" that compiled by Wang-Xi(王圻), the form of Bansu was appeared to be transformed as the half-round pond. And the half-round pond as called Banji(泮池) of today's form was all rebuilt after Ming Dynasty. The half-moon pond appeared at the private houses, shrines, temples and villages were influenced by the book. From this research we can get the conclusions that Banji seemed one of the sacred one and used in the space arrangement formally for the various functions. This research has found the cultures of half-moon ponds which were used uniquely in China.

Background: The aortic arch replacement in an acute aortic dissection is technically demanding procedure that has a lot of postoperative morbidity and high mortality The authors have applied several techniques of aortic arch replacement to overcome the risks of the procedure. Therefore we analysed the results of these techniques. Material and Method: From March of 1996 to July of 2002, we performed 31 cases of the aortic arch replacement in the Stanford type A acute aortic dissection. There were 12 male and 19 female patient's with 59.6$\pm$9.4 years of mean age. Among them 18 cases were treated with the hemiarch replacement and 13 cases with the total arch replacement. We approached the aortic arch through median sternotomy in all but 3 cases of Clamshell incision and applied the deep hypothermic circulatory arrest with retrograde cerebral perfusion. The associated procedures were 2 Bentall's procedures, an axillobifemoral bypass, a femorofemoral bypass and a carotid artery bypass. Result: The postoperative morbidities were 8 acute renal failures, 3 CNS complications, 2 low cardiac output syndromes, 2 malpefusion syndromes, and 2 deep wound infections. There were 4 cases of early hospital mortality which were from an acute renal failure a postoperative bleeding, a low cardiac output syndrome, and a reperfusion syndrome. There were 3 cases of late hospital mortality which were from an acute renal failure, and 2 multiorgan failures. So the total mortality rate was 22.5%. There were 4 cases of late mortality after the discharge, which were form 2 cases of distal anastomotic rupture and 2 cases of intracranial hemorrhage. Conclusion: The hemiarch replacement has relatively shorter operative time and lower hospital mortality but higher late mortality than the total arch replacement. The total arch replacement needs more technically demanding procedure.
