Large complex buildings have been constructed to make every work effectively in large cities. The large complex building which features a large number of occupants and complex circulation makes it difficult to complete the emergency egress In some cases in which the fire generates the products of combustion, the smoke causes the reduction of the visibility and this may have a decisive effect on egress time. The smoke flowing through the stair case can’t be ignored by the evacuee in the high rise building. Because of this, the smoke control system is required by law. However, the smoke control system can’t work properly under the condition of that the fire doors are opened. Therefore, this paper is focusing on the assessment for smoke concentration by analyzing on the egress time when the smoke flows through the stair case. 96 subjects participated in this egress drill and the visibility was limited by the fog machine in order to simulate conditions in case of fire. As a result, the descent speeds in normal and smoke layer decrease by 31% and 55% for each as 0.92㎧ and 0.59㎧. Furthermore, it was found that the evacuation speed decreases as the extinction coefficient increases and the evacuation speed at the minimum extinction coefficient was 0.7㎧.

Hip ankylosis can be caused by the sequela of septic arthritis, osteoarthritis, tuberculous arthritis and hip joint arthrodesis from treatment of severe arthritis in young patients. It is known that an unilateral fused hip results in an unusual change of gait pattern, followed by other joint problems. However, no pre-vious study has examined the assessment of gait pattern precisely through clinical and quantitative gait laboratory data. The purposes of this study were to evaluate the gait pattern of patients with unilateral hip ankylosis, objectively and quantitatively, and to determine how the gait pattern affects other joints. We evaluated the relationship between the quantitative gait data obtained from 30 patients with unilat-eral hip ankylosis who did not show any limitation of motion in the contralateral hip, and the data from 20 normal controls. We also assessed the statistical relationship among the data of other joints, such as the opposite hip of the fused hip and both knees. Compared to normal controls the results of this study demonstrated that the gait pattern of the patients was slow, asymmetrical, arrythymic and the patients showed increased upward-downward pelvic tilt, obliquity, rotation, continuous flexion and overload of the knee on fused hip, excessive motion and stress of the hip of the sound side(p<0.05). The correlations that were obtained among the gait data were presented with excessive motion and stress of the lumbar area, the hip on the sound side and the knee on the fused side. These affects caused the clinical problems such as pain, and limitation of motion of the low back, the hip on contralateral side and the knee on ipsi-lateral side. Finally, through the gait analysis of the patients with unilateral hip ankylosis, we found that unilateral hip fusion can affect other joints adversely. These findings suggest that the surgeon needs to use care when performing unilateral hip fusion in young patients. In conclusion, as compared with the gait pattern of the controls, we recognized that the patients with unilateral hip ankylosis appeared to have a different gait pattern by the quantitative gait laborato-ry data, and this gait pattern could cause clinical problems of other joints.

The bone infection after hip arthroplasty which can bring a catastrophic results to the patient has been problem due to the difficulties in the diagnosis and treatment. To solve this problem, infectionspecific WBC scan has been developed. Recently "Tc-HMPAO(Technetium-99m hexamethylpropylene-amineoxime)-WBC scan was introduced and have been adopted for detection of infection. However the diagnostic value and possible problem have not been proved yet. The authors attempted to find out the diagnostic value and limitation of " Tc-HMPAO-WBC scan in the infection after hip arthroplasty. Twenty-five patients, who underwent " Tc-HMPAO-WBC scan from October 1994 to February 1997 in Asan Medical Center, were analysed. Through comparing the results of " Tc-HMPAO-WBC scan with operative, microbiologic, radiologic and clinical findings, we have reached the following conclusions. 1. ""Tc-HMPAO-WBC scan was very sensitive to the detection of bone infection after hip arthroplasty. 2. The delayed imaging decreased the false negative rate, but the problem of detection of subacute or chronic infection should be studied. 3. The false positive rate was relatively low, and when we combine Tc-MDP bone scan with Tc-HMPAO-WBC scan, probably the false positive rate will be decreased more than now. 4. Single Photon Emission Computed Tomography(SPECT) could help to localize the infection focus and detect the low activity of infection.

The purpose of this study is to draw for characteristics of crowd movement in a corridor. Generally, a corridor determines the number of floating population who moves to other places. Therefore, to solve the congestion caused by specific area such as exit door, the study of crowd movement in corridor is needed. In this study, to inquire the relationship between the number of participant with crowd, density and flow, a full-scale experiment has been done in acorridor which has 1.2m width. The result was that crowd speed decreased as increasing the number of participants. For that crowd speed, the head-participant speed in front of crowd was predominated for crowd speed. Also the modified equation for crowd density-crowd speed suggested through measured crowd density and speed.

이수호(Soo-Ho Lee),조수현(Su-Hyun Cho),남태석(Tae-Seok Nam) 대한정형외과학회 2004 대한정형외과학회지 Vol.39 No.6

목적: 금속-금속 관절면에서의 논쟁의 초점인 금속 이온 유리가 실재하는지와 골두의 직경이 큰 금속-금속 관절면 고관절 표면치환술(hip resurfacing arthroplasty)과 상대적으로 작은 전치환술(total hip arthroplasty)에서 유리 정도에 차이가 있는지 알아보고자 하였다. 대상 및 방법: 본원에서 1998년 6월부터 2003년 4월까지 수술 후 추시 중 금속 이온 농도 측정이 가능하였던 금속-금속 관절면 고관절 표면치환술(평균 골두 직경 47.1 ㎜) 42예와 전치환술(골두 직경 28㎜) 39예에서 나이, 체중 및 수술 후 검사 기간이 조화되는 환자, 각 21예를 대상으로 혈중 코발트와 크롬 이온 농도를 비교하였다. 정상 대조군은 세라믹-세라믹 관절면 고관절 전치환술을 시행받은 환자로 하였다. 금속 이용 농도는 환자의 혈청을 희석하여 유도 결합 플라즈마 질량 분석기(inductively-coupled plasma mass spectrometry, Agilent 4500, Rhode Island, USA)로 측정하였다. 결과: 혈중 코발트와 크롬 모두 금속-금속 관절면 양군에서 대조군에 비하여 증가된 소견을 보였다. 또한 금속-금속 관절면 양군간의 비교에서는 표면치환술군이 전치환술군에 비해 혈중 코발트는 증가된 소견을 보였으나(p=0.025), 크롬은 통계적인 차이를 보이지 않았다(p=0.50l). 결론: 금속-금속 관절면의 사용시 금속 이온의 유리는 실재하며, 큰 골두 직경을 사용하는 표면치환술에서 더 높은 코발트 농도를 보였다. 그러나 이의 임상적 의의는 장기적인 추시가 필요하다고 생각된다. Purpose: To verify that the metal-on-metal (MOM) surfaces produce metal ions and to ascertain the differences between large and small femoral head diameters with regard to the release of metal ions. Materials and Methods: Forty two cases of MOM hip resurfacing arthroplasty (mean head diameter: 47.1 ㎜) and 39 cases of conventional total hip replacement arthroplasty (head diameter: 28 ㎜) were performed at our hospital from June 1998 to April 2003. All the cases were followed-up using the serum cobalt and chromium ion levels. The serum cobalt and chromium ion levels were compared in the 21 cases in each group, which were matched by age, weight and follow-up period. The control group involved 21 patients who had undergone an alumina-alumina total hip arthroplasty. The patient's serum metal ion concentration was measured from the serum, which had been separated from the whole blood and diluted using inductively-coupled plasma mass spectrometry (Agilent 4500, Rhode Island, USA). Results: All MOM bearing implants produced higher serum levels of cobalt and chromium ions than the control. The serum concentration of cobalt with MOM resurfacing was higher than that observed with a 28 ㎜ MOM total hip arthroplasty (p=0.025), but the chromium levels were not significantly different (p=0.501). Conclusion: The MOM bearing implants in this study produced elevated serum levels of cobalt and chromium ions. In addition, large diameter heads resulted in greater systemic exposure of cobalt ions than the small diameter heads. However, a long-term follow-up will be needed to determine the clinical significance.

이수호 ( Soo Ho Lee ),백동훈 ( Dong Hoon Baek ),강석중 ( Seok Joong Kang ),조수현 ( Su Hyun Cho ) 대한고관절학회 2005 Hip and Pelvis Vol.17 No.4

목적: 고관절 자체의 동통 뿐만 아니라 인접 관절의 동통, 강직에 의한 고도의 기능적 제약 등도 적응증이 되는 강직성 고관절의 전치환술로의 전환에 있어 술후 임상적 결과에 영향을 미치는 예후인자들을 분석하여 수술 여부의 결정 등에 도움을 주고자 하였다. 대상 및 방법: 46명, 53고관절을 대상으로 하였으며 추시 기간은 평균 3년 4개월이었다. 예후 인자로 강직의 종류, 강직 시기 및 강직 기간, 외전근의 발달 정도, 선행 질환, 하지 부동의 정도, 삽입물의 종류, 대전자 절골술의 시행 여부 등을 분석 대상으로 하였다. 이에 따른 임상적 결과로 수술 전후의 Harris 고관절 점수(동통, 보행, 활동도), 고관절 운동범위 및 인접 관절의 동통 완화도 등을 후향적으로 조사하여 예후 인자로서 의미 있는 변수가 무엇인지를 통계학적으로 분석하였다. 결과: 골성 강직보다 고도의 섬유성 강직이, 외과적 강직보다 자발적 강직이, 15세 이전보다 이후에 발생한 강직이 Harris 고관절 점수와 인접 관절 동통 완화도에서 보다 의미 있는 호전을 보였으며, 외전근의 강한 수축력이 Harris 고관절 점수 중 특히 보행에 중요한 예후인자로 나타났다. 결론: 강직성 고관절에 관절 가동성을 부여하는 전치환술로의 전환에서는 예후 인자를 미리 파악하여 환자의 요구에 응하는 것이 중요하다고 사료된다. Purpose: To analyze the prognostic factors influencing clinical outcomes and to aid the surgeon`s decision making concerning conversion of ankylosed hip to total hip arthroplasty (THA). Materials & Methods: Forty-six patients (53 hips) with a mean follow-up duration of 3 years 4 months were studied. Prognostic factors including type of ankylosis, age at fusion, abductor development, fusion duration, preceding diseases, leg length discrepancy, implant type, and trochanteric osteotomy were analyzed. Clinical results were evaluated retrospectively using Harris hip score (HHS; pain, gait, activity), pain scale of adjacent joints, and range of motion. Results: Favorable prognosis factors were severe fibrous ankylosis, spontaneous ankylosis, and age at fusion over 15 years. Unfavorable factors were bony ankylosis, surgical ankylosis, and age at fusion under 15 years in HHS and pain scale of adjacent joints. Strong contraction of the abductor muscle was also an important prognosis factor in HHS, especially in gait. Conclusion: In conversion of ankylosed hip to THA, it is important to recognize the possible prognostic factors and to meet the patient`s various demands and needs.
