One of the most lethal forms of mediastinitis is descending necrotizing mediastinitis, in which infection arising from the oropharynx spreads to the mediastinum. Despite the development of computed tomographic scanning to aid in the early diagnosis of mediastinitis, the past 30 years, in large part because of continued dependence on transcervical mediastinal drainage, Although transcervical drainage is usually effective in the treatment of acute mediastinitis due to a cervical esophageal perforation, these approach in the patient with descending necrotizing mediastinitis fails to provide adequate drainage and pre-disposes to sepsis and a poor outcome. In addition to cervical drainage, aggressive, early mediastinal exploration - debridement and drainage through a subxiphoid incision or thoracotomy - is advocated to salvage the patient with descending necrotizing mediastinitis.

We experienced a case of traumatic aneurysm of descending thoracic aorta by an automobile accident. The patient was 23-year-old-male with a traumatic aortic aneurysm [6x12cm] on the descending thoracic aorta just distal to the origin of the left subclavian artery. Exposure was obtained through a left posterolateral thoracotomy incision in the fourth intercostal space and then partial femoro-femoral cardiopulmonary bypass was established.After aortic cross- clamping, the aneurysmal sac was opened and repaired with interposition of Dacron vascular graft and aortic cross-clamping period lasted for 100 minutes. Postoperative bleeding and vocal cord paralysis were complicated, but bleeding was controlled by reoperation and vocal cord paralysis was improved. Follow up was continued for 14months and postoperative course was uneventful.

Takayasu`s arteritis is one of chronic inflammatory disease characteristically involving the aorta and it`s major branches. We experienced two surgical cases of Takayasu`s arteritis associated with the stenosis of the descending thoracic aorta. One case was 15 year-old girl and she was admitted because of dyspnea on exertion for 12 months. Aortogram showed the stenosis of the descending thoracic aorta from just below left subclavian artery to the 9th thoracic vetebra. The other case was 10 year-old girl and she was admitted because of URI and hypertension. Aortogram showed narrowing of right innominate artery, but developed collateral circulation, and the stenosis of the descending thoracic aorta near the 9th thoracic vertebra. In each case, bypass graft from the ascending aorta to the abdominal aorta just above the inferior mesenteric artery was performed with satisfactory result.

Purpose: The purpose of this study was to compare the pathway of COP and plantar foot pressure and to determine the correlation between plantar regions during the ascending and descending of a ramp. Methods: Fifteen healthy adults who had no musculoskeletal problems participated in our study. They were asked to walk on a level surface and on an ascending and descending ramp in their bare feet. Pathway of COP and plantar foot pressures were recorded using the Matscan system (Tekscan, Boston, USA). For pressure measurements, the plantar foot surface was divided into seven regions: two toe regions, three forefoot regions, a midfoot region, and a heel region. To determine whether there was a statistically significant difference between pathway of COP and plantar foot pressures during walking, we used repeated measuremes ANOVA. Results: In comparison to results for a level walking, pathway of COP while ascending a ramp had a tendency to be shifted medially in the forefoot and became longer till the big toe. Pathway of COP while descending a ramp also was shifted medially, but ended in the forefoot. Plantar foot pressure of the second and third metatarsal head and the fourth and fifth metatarsal heads was significantly decreased while descending the ramp. Conclusion: These results indicated that plantar foot pressure is changed while ascending and descending a ramp and demonstrated that ramp walking can affect the structure and function of the foot. Therefore, gait environment is associated with significant changes in foot characteristics, which contribute to altered plantar loading patterns during gait.

The purpose of this study is to establish design guidelines for waterscape facilities of healing gardens in psychiatric hospitals. Data were collected through simulation and interview. The subjects included schizophrenic (n=42) and alcoholic (n=41) inpatients as well as medical staff personnel (n=40) at Maeumsarang Hospital. The results of this study are as follows: It was revealed that for all three groups the first preference was a natural flowing waterscape, and the second preference was a natural descending waterscape. The schizophrenic subjects had a greater preference for a static artificial waterscape and a descending artificial multistory waterscape than the other two groups. The alcoholic subjects preferred an ascending natural multistory waterscape. The analysis on the preference towards an ascending type and a descending type from the perspective of naturalness and complexity. Complexity had a greater influence than naturalness in the ascending waterscapes, and naturalness had more influence than complexity in the descending style waterscapes. Therefore, these factors need to be taken into consideration when designing either ascending or descending waterscape facilities. In general, the subjects preferred natural, dynamic and descending waterscapes to the artificial, static and ascending variety.

This study aims to investigate the effects of ankle foot orthosis(AFO) on the activities of tibialis anterior(TA), soleus(Sol), rectus femoris(RF) and biceps femoris(BF) during stairs descending. The activities of TA, Sol, RF and BF were initially measured while descending 4 stairs without using AFO. The activities of the same muscles were then measured again while descending 4 stairs while using AFO. Wilcoxon signed-rank tests were used to analyze the results in order to examine the differences between the with using AFO and without using AFO. Although the activities of TA, Sol and RF were relatively lower while using AFO than without using AFO, only the differences in Sol and RF activities were significant(p<0.05). The activity of BF was relatively higher while using AFO compared to the activity of BF observed without using AFO. However, difference was not significant(p>0.05). Conclusion of this study was observed since AFO's ground reaction force absorption during stairs descending reduced the need to use So and RF that is related to shock absorption. BF activity was increased with AFO than without during standing forward to correct the trunk stability.

Recently, a new concept of a one-touch descending lifeline has been proposed to address the drawbacks of the conventional descending lifeline, which can be easily installed and quickly evacuated in the case of a fire emergency. All separate parts for escape are initially mounted in a box, and the link-type support is spread out of the window by pushing the handle attached to the box. In this study, the proposed double square linkage mechanism was redesigned, and its safety is verified by determining an appropriate moment of inertia of the link through finite element analysis using Abaqus. The shape and assembling method of the reel and speed controller were also modified such that the safety belt was simultaneously unfolded with link-type support. Finally, the feasibility of the proposed one-touch all-in-one descending lifeline was confirmed through fabrication.

A 42-year-old Marfan female had a chronic dissection of the descending aorta[Type B and the aneurysmal expansion of the descending aorta caused compression of the trachea resulting in respiratory distress which mimicked bronchial asthma. The patient has been successfully managed by resection and replacement of the aneurysm in the descending aorta. The operation could be done without the aid of the partial cardiopumonary bypass. As the patient had been prepared by unilateral axillo-bifemoral by-pass using prosthetic graft 8mm in diameter 10days prior to the main operation.
