도시화, 산업화, 기후 변화 등으로 인해 자연재난의 발생 횟수 및 피해규모가 증가하고 있다. 재난이 발생하게 되면 도시의 기능이 저하되고, 복구하기 위해서는 오랜 시간이 필요하다. 특히 교통시스템은 도시의 핵심 기반시설로서 재난에 대응하기 위한 계획이 필요하다, 이로 인해 재난에 효과적으로 대응하기 위해 재난 분야에서는 Resilience 개념의 중요성이 부각되고 있고 Resilience를 분석하기 위해 다양한 개념들이 사용되지만 개념 간의 차이를 명확하게 구분하는 것이 어려운 실정이다. 본 연구에서는 Resilience에 대한 정량적 분석에 초점을 맞추어 재난 발생 전 사전투자에 대한 Robustness와 재난 발생 후 복구에 대한 Rapidity를 이용하여 도로망의 Resilience를 정량적으로 평가하였다. Resilience에 대한 정량적 효과 분석을 통해 의사결정시 새로운 판단지표를 제시하였고 이는 도로 사업에 대한 타당성 평가 등에 있어서 새로운 관점을 제시할 수 있을 것으로 보인다.

차량과 인프라 간의 V2X 무선통신이 가능한 커넥티드(connected) 환경에서 위험 상황을 사전에 회피하기 위한 선제적 교통관리전략 수립이 요구된다. 자율차와 비자율차의 안전한 도로주행을 위한 거동제어 및 의사결정을 지원하는 교통정보 제공은 인프라 협력 환경에서 현실화 될 수 있다. 따라서 본 연구의 목적은 커넥티드 환경에서 자율 및 비자율 차량이 혼재된 교통류 관리를 위한 인프라 협력형 선제적 차로변경지원 정보 제공 전략(Proactive LanechangE Assistant Strategy for Automated iNnovative Transportation, PLEASANT)을 개발하고 평가하는 것이다. PLEASANT는 전방 교통사고, 고장차량, 낙하물과 같은 돌발상황 발생 시 상류부에서 진입하는 차량의 사전 차로변경을 유도하기 위한 교통정보를 제공 및 공유하는 방안이다. 본 연구에서 제안한 전략은 주행-교통 시뮬레이션 연계 기반의 방법론을 통해 평가되었다. 주행 시뮬레이션은 자율 및 비자율 차량추종 상황에서 후행 비자율차의 주행행태를 분석하기 위하여 활용되었다. 주행 시뮬레이션으로부터 도출된 비자율차의 주행특성은 교통 시뮬레이션에 반영되었다. 교통 시뮬레이션은 교통정보를 제공받는 차량의 거동을 구현함으로써 PLEASANT의 효과평가를 목적으로 사용되었다. 커넥티드 환경에서 PLEASANT 적용 시 이동성 및 안전성은 최대 각각 약 75%와 21% 증대되는 것으로 도출되었다. 본 연구에서 개발한 PLEASANT는 자율차와 비자율차의 운전자에게 가용한 차로변경 수행 시간을 충분히 제공하여 혼잡상황을 예방할 수 있을 것으로 기대된다.
在车辆和基础设施之间可以进行V2X无线通信的connected环境中，为了事先回避危险状况，需要树立先发制人的交通管理战略。为了自律车和非自律车的安全道路行驶，提供行动控制及决策支持的交通信息，可以在基础设施合作环境中成为现实。因此，本研究的目的是开发和评价在网络环境中自律和非自律车辆混合的交通类管理的基础设施协作型先发性车道变更支援信息提供战略(Proactive LanechangE Assistant Strategy for Automated iNnovative Transportation, PLEASANT)。PLEASANT是在发生前方交通事故、故障车辆、坠落物等突发状况时，为引导从上游进入的车辆提前变更车道，提供并共享交通信息的方案。本研究提出的战略是通过基于行驶-交通模拟连接的方法论进行评价的。行驶模拟实验被用于分析后行非自动率车在自主和非自动率车辆追踪情况下的行驶形态。从行驶模拟得出的非比例车的行驶特性反映在了交通模拟中。交通模拟实验的目的是评估PLEASANT的效果，以体现车辆接受交通信息的行为。在网络环境中使用PLEASANT时，移动性和安全性分别提高了75%和21%。本研究开发的PLEASANT为自由车和非自由车的司机提供了充分的变更可用车道的时间，可以预防混乱状况。

Objective People take anti-thrombotic agents due to many medical conditions. The aim of this study was to determine whether the use of these drugs affects the likelihood of surgery in patients with chronic subdural hematoma (CSH), with consideration of other factors. Methods This study analyzed clinical and radiological data of 348 patients who were diagnosed with CSH between January 2011 and December 2021. In total, 254 patients were included. We investigated clinical and radiological findings to identify factors that were associated with the likelihood of surgery in CSH. Results Initial Glasgow coma scale (GCS) and radiological factors, such as hematoma thickness, density type, midline shifting, and laterality, were significantly related to the likelihood of surgery (P<0.05). The use of anti-thrombotic drugs in patients with trauma (P=0.043) or chronic alcoholism (P=0.018) was associated with the likelihood of surgery. The use of anti-thrombotic drugs was associated with the density type (P=0.037) of computed tomography scans, but head trauma was not significantly related to the likelihood of surgery. The use of anti-thrombotic drugs was significantly related to the recurrence of CSH (P=0.021). Conclusion This study reported that the initial GCS and several radiological factors were significantly associated with the likelihood of surgery in CSH. Especially in patients taking anti-thrombotic drugs, head trauma or chronic alcoholism was significantly associated with the likelihood of surgery. Close monitoring of these patients is suggested.

Objective The incidence of chronic subdural hematoma (CSDH) and its peak age of occurrence are increasing with the rapid progression of population aging. Surgical treatment for symptomatic CSDH has shown favorable clinical outcomes (>80%). Since some recent reports have described unfavorable outcomes of surgical treatment of CSDH in older patients, we evaluated the functional outcomes of CSDH in older patients. Methods We retrospectively analyzed the functional outcomes of CSDH patients aged >60 years who underwent burr-hole surgery between January 2017 and December 2021. Using the modified Rankin scale (mRS), we analyzed the functional outcomes of burr surgery and investigated the factors affecting the surgical outcomes. Results In total, 172 patients (115 men and 57 women) were analyzed for the functional outcomes of surgery. Functional outcomes improved in 120 patients (69.8%) and worsened in 52 patients (30.2%). Age (P=0.046), preoperative mRS (P=0.002), and the presence of underlying disease (P=0.025) were factors affecting the postoperative functional status. Conclusion The decision regarding surgical treatment of CSDH in older patients should be made carefully, considering their preoperative functional status and underlying disease.

Objective We conducted a retrospective study involving 348 patients with suspected chronic subdural hematoma who underwent burr-hole trephination. The primary objective was to examine the relationship between the postoperative subdural drainage catheter's position and the recurrence rate. Methods In a retrospective study conducted at Ewha Womans University Mokdong Hospital between September 2020 and August 2023, patients diagnosed with chronic subdural hematoma underwent surgical intervention. We defined the recurrence of chronic subdural hematoma as an increase in the volume of subdural fluid on the treated side compared to the volume measured just before the computed tomography scan was performed. Results The recurrence rates were not significantly different between these 2 groups (20.3% vs. 20.5%, P=0.594). Additionally, there was no significant difference in mean age (74.9 vs. 75.8 years, P=0.733), male-to-female ratio (3.29 vs. 3.25, P=0.478), or maximum depth (13.5 mm vs. 12.7 mm, P=0.323) between the 2 groups. Conclusion There was no significant difference in the recurrence rates between the 2 groups. This suggests that the location of the burr-hole trephination and the subdural catheter tip location might have had no significant impact on patientsâ prognosis. In order to reduce the recurrence rate of chronic subdural hematoma, making efforts to minimize other factors like subdural air collection is important.

目的对348例疑似慢性硬膜下血肿患者行钻孔穿刺治疗进行回顾性研究。主要目的是探讨术后硬膜下引流管放置位置与复发率的关系。方法2020年9月至2023年8月在梨花女子大学木洞医院进行回顾性研究，诊断为慢性硬膜下血肿的患者接受手术干预。我们将慢性硬膜下血肿复发定义为治疗侧硬膜下积液量较计算机断层扫描前测量的体积增加。结果两组患者复发率差异无统计学意义(20.3% vs. 20.5%， P=0.594)。此外，两组患者的平均年龄(74.9比75.8岁，P=0.733)、男女比(3.29比3.25,P=0.478)和最大深度(13.5 mm比12.7 mm, P=0.323)均无显著差异。结论两组患者的复发率差异无统计学意义。提示钻孔穿甲术的位置和硬膜下导尿管尖端的位置可能对患者的预后没有显著影响。为了降低慢性硬膜下血肿的复发率，努力减少其他因素如硬膜下空气收集是很重要的。关键词:慢性硬膜下血肿;导管尖端位置;复发率
{"title":"Postoperative recurrence rates in chronic subdural hematoma patients who underwent burr-hole trephination with parietal or occipital drainage compared to frontal drainage","authors":"Jae Hwan Tae, Myung-Hyun Kim, Young Goo Kim, Sung-Kyun Hwang","doi":"10.51638/jksgn.2023.00101","DOIUrl":"https://doi.org/10.51638/jksgn.2023.00101","url":null,"abstract":"Objective We conducted a retrospective study involving 348 patients with suspected chronic subdural hematoma who underwent burr-hole trephination. The primary objective was to examine the relationship between the postoperative subdural drainage catheter's position and the recurrence rate. Methods In a retrospective study conducted at Ewha Womans University Mokdong Hospital between September 2020 and August 2023, patients diagnosed with chronic subdural hematoma underwent surgical intervention. We defined the recurrence of chronic subdural hematoma as an increase in the volume of subdural fluid on the treated side compared to the volume measured just before the computed tomography scan was performed. Results The recurrence rates were not significantly different between these 2 groups (20.3% vs. 20.5%, P=0.594). Additionally, there was no significant difference in mean age (74.9 vs. 75.8 years, P=0.733), male-to-female ratio (3.29 vs. 3.25, P=0.478), or maximum depth (13.5 mm vs. 12.7 mm, P=0.323) between the 2 groups. Conclusion There was no significant difference in the recurrence rates between the 2 groups. This suggests that the location of the burr-hole trephination and the subdural catheter tip location might have had no significant impact on patientsâ prognosis. In order to reduce the recurrence rate of chronic subdural hematoma, making efforts to minimize other factors like subdural air collection is important.
