소방특별사법경찰제도의 효율적인 운영방안에 관한 연구

정현균,황의홍,최돈묵 한국방재학회 2019 한국방재학회논문집 Vol.19 No.3

2017년 소방청 통계를 분석해보면 최근 3년간 소방활동 방해사범은 528건으로 해마다 증가 추세에 있다. 그러나 일선 소방서는 현재 소방활동 방해사범을 적발하고 송치할 수 있는 수사 전담팀을 효율적으로 운영하지 못하고 있어 소방활동 방해사건이 발생하여도 현행범인으로 체포하는 과정을 경찰에 의존하는 등 적극적인 대응이 이루어지지 못하고 있는 것이 현실이다. 본 연구에서는 소방청 통계를 바탕으로 전국에서 화재·구조·구급·출동건수 1위 지역인 경기도 소방관서의 소방특별사법경찰 의 운영기준과 한계를 분석하고, 이에 대한 문제점과 해결방안을 제시하였다. According to the analysis of the National Emergency Management Agency's statistics in 2017, there have been 528 cases of interference in firefighting activities over the past three years, and has been increasing every year. However, since the fire department has not been able to efficiently operate a task force that can detect and transmit fire activities, it is not actively responding by relying on the police to arrest the suspect even if there is an obstruction of fire. Based on the statistics of the fire department, this study analyzed the operation standards and limitations of the fire department in Gyeonggi Province, which ranks first in the number of fires, rescues, and rescue operations in the whole country, and presented problems and solutions for them.

The purpose of this study was to present the clinical analysis of the results of lateral arm free flap for small sized and infected diabetic foot ulcer around toes. From May 2006 to December 2007, Seven patients were included in our study. Average age was 52.8 years, six were males and one was female. All had infected diabetic foot ulcer and had exposures of bone or tendon structures. Ulcers were located around great toe in four patients, 4th toe in one and 5th toe in two. Three patients had osteomyelitis of metatarsal or phalanx. After appropriate control of infection by serial wound debridement and intravenous antibiotics, lateral arm flap was applied to cover remained soft tissue defects. Posterior radial collateral artery of lateral arm flap was reanastomosed to dorsalis pedis artery of recipient foot by end to side technique in all cases in order to preserve already compromised artery of diabetic foot. All flaps were designed over lateral epicondyle to get longer pedicle and averaged pedicle length was 8 cm. Two cases were used as a sensate flap to achieve protective sensation of foot. All flaps survived and provided satisfactory coverage of soft tissue defects on diabetc foot ulcers. All patients could achieve full weight-bearing ambulation. No patients has had recurrence of infection, ulceration and further toe amputations. There were three complications, a delayed wound healing of flap with surrounding tissue, a partial peripheral loss of flap and a numbness of forearm below donor site. All patients were satisfied with their clinical results, especially preserving their toes and could return to the previous activity levels. Lateral arm free flap could be recommend for infected diabetic foot ulcers around toes, to preserve toes, coverage of soft tissue defect and control of infection with low donor site morbidity.

The purpose of this study was to present the clinical result of anterolateral thigh free flap for pretibial soft tissue lesion after chronic tibia osteomyelitis. From December 2006 to September 2008, Five patients were included in our study. 4 of 5 were superficial or localized types of chronic tibia osteomyelitis, based on the classification of Cierny and Mader. Average age at the surgery was 45 years, three were males and two were females. All had a history of chronic tibia osteomyelitis and subsequent pretbial soft tissue lesions coming from previous operations or pus drainage. Pretibial soft tissue defects included small ulcers, fibrotic, bruisable soft tissue and small bony exposures, but not large-sized bony exposures nor active pus discharge. After complete debridement of large sized pretibial soft tissue lesions and decortication of anterior tibial cortical dead bone, anterolateral thigh free flap was applied to cover remained large pretibial soft tissue defect and to prevent the recurrence of infection. All flaps survived and provided satisfactory coverage of soft tissue defect on pretibial region for 16 months' mean follow up period. No patients has had recurrence of osteomyelitis. Anterolateral thigh free flap could be recommend for large sized pretibial soft tissue defect of supreficial or localized types of chronic tibia osteomyelitis after through debridement.

Study Design: A prospective study. Objectives: To evaluate the effectiveness of ultrasound guidance in caudal epidural block and sonographic feature of sacral hiatus. Summary of Literature Review: High success rate of ultrasound-guided regional nerve block has been reported and recently, ultrasound-guided nerve block in spinal field has been introduced. Materials and Methods: Ultrasound-guided caudal epidural block was performed in 48 patients with radiating pain to leg. Patient was placed in the prone position and sonographic image of sacral hiatus was obtained using linear probe. After measuring the intercornual distance, thickness of sacrococcygeal membrane and depth of sacral canal in transverse view, then the probe was rotated 90° to obtain the longitudinal view of the sacral hiatus. Under ultrasound guidance, a 21-gauge needle was inserted into the sacral hiatus in parallel with sacrum base. After contrast dye injection, needle placement was checked by the fluoroscopy and then medication was injected into the caudal epidural space. We investigated the change of radiating pain after caudal epidural block using visual analogue scale(VAS). Results: The intercornual distance was mean 16.4±2.3mm, thickness of sacrococcygeal membrane was mean 2.8±0.9mm and depth of sacral hiatus was mean 2.6±0.9mm. There was 97.9% success rate of the caudal epidural block under ultrasound guidance. The mean VAS for radiating pain was improved from 7.5±0.7 before the block to 2.8±1.5 after the block. Conclusions: Ultrasound-guided caudal epidural block seems to provide good anatomical landmark of sacral hiatus and an effective tool with high success. 연구 계획: 전향적 연구. 목적: 미추경막외 차단술에서 초음파 유도의 유효성과 천추 열공의 초음파적 특성을 알아보고자 하였다. 선행문헌의 요약: 국소신경차단술 시 초음파를 이용하여 높은 성공률이 보고되고 있으며 최근 척추 분야에서도 초음파를 이용한 신경차단술이 소개되고 있다. 대상 및 방법: 하지 방사통을 호소하는 48명의 환자를 대상으로 초음파 유도하 경막외 차단술을 시행하였다. 환자를 복와위 자세로 눕힌 후 선형 탐지자를 이용하여 천추 열공 부위의 초음파 영상을 확인하였다. 가로축상 화면을 통해 두 천골 뿔간의 거리, 천-미추막의 두께 및 천추관의 깊이를 측정한후 탐지자를 90도 회전시켜 미추관의 중앙 시상 초음파 영상을 확인하고 초음파 유도 하에 21G 바늘을 미추관의 바닥면과 평행하게 삽입하여 바늘이천-미추막을 통과하는 것을 확인하였다. 그 후 조영제를 주입한 후 방사선투시검사로 주사침의 위치와 천추관내 경막외 조영 소견을 확인하고 칵테일동통주사를 미추경막외 공간에 주입하였다. 미추경막외 차단술의 동통 변화를 시각통증척도를 이용하여 임상적 평가를 하였다. 결과: 천추 열공의 초음파상 해부학적 두 천골 뿔간 거리는 평균 16.4±2.3mm , 천-미추막의 두께는 평균 2.8±0.9mm, 천추관의 깊이는 2.6±0.9mm 이었다. 초음파 유도 하 미추경막외 차단술은 48예 중 47예에서 바늘이 성공적으로 삽입되어 97.9%의 성공률을 보였다. 초음파 유도 하 미추경막외 차단술 후 동통의 변화는 시술 전 평균 VAS 7.5±0.7에서 차단술 후 VAS 2.8±1.5으로 호전된 결과를 보였다. 결론: 초음파를 이용할 시 천추 열공의 해부학적 표지 확인이 용이하였으며, 미추경막외 차단술에 초음파 유도하 시술은 바늘 위치의 높은 성공률이 보장되는 유효한 술식으로 사료된다.

Recent projects for transferring Public Office buildings and estimation of appropriate construction expense are highly important for both government and construction firms. Moreover, estimation and management of construction expense can be regarded as extremely important duties for effective execution of a national budget as nation’s finance is invested in the Public office building projects progressed by the government. To progress one project for Public office building, not only the organization demanding the project but also an investment screening organization, a budget-managing organization, a feasibility assessment institution and many other related organizations participate in the project and a lot of decisions arisen from the project operation are made on the basis of construction expenses calculated for relevant stages. And estimation of rational construction expense is also critical for designers in order to create design within the fixed budget simultaneously with securing the quality and efficiency of structures to the maximum. Therefore this research suggested an improvement process to analyze problems in current construction expense management process and to administer the construction expenses effectively.
