국내 건설시장 개방과 건설경기 침체에 따른 과당경쟁, 급속한 정보기술의 발달과 시시각각 변화하는 동태적인 사회 환경 등이 건설 환경을 급속하게 변화시키고 있으며, 이에 따라 건설사업에서의 리스크 또한 현저하게 증가하고 있다. 또한, 이러한 리스크를 다루는 리스크 관리가 사업의 성패와 부가가치 결정에 커다란 영향을 주고 있어 건설사업에서의 리스크 관리가 철실히 필요한 시점이다. 본 연구에서는 국내개발사업 사전기획단계에서의 제한된 정보를 이용하여 효과적으로 리스크를 관리 할 수 있도록 주요 리스크 인자 식별 및 분류를 통해 통계적 기법으로 중요도를 분석하고, 기획단계별 주요 리스크 인자를 분류하여 기존의 경험에 의존한 직관적이고 주관적인 리스크 관리를 보다 객관적으로 수행할 수 있도록 하는 기초를 마련하였다. The construction market is diversely changing because social environmental factors are rapidly transforming. Therefore, Construction projects are becoming complex and diverse. Furthermore, the risk being inherent in construction projects are increasing, and now people are considering about the risk management of construction projects in successfully handling the risk factor. The purpose of this study is first to comprehend the preparation of basic references for objective and systematic identification, categorization, and analysis of risk. Secondly it is to find the principle elements within the risk factors identified and categorized around planning process. Finally it is to manage objectively on the planning process, which forms a lot of uncertainty, in order to accentuate the importance about the risk of pre-planning process stage

추후 관찰이 가능하였던 26례의 환자들이 평균 9개월의 짧은 생존기간을 보이는 것으로 보아 환자들에게 고통을 적게 주고 효과적인 비용의 검사를, 즉 흉부 방사선 사진, 복부 초음파, 흉부 전산화 단층 촬영, 복부-골반 전산화 단층 촬영, 기관지 내시경, 소화기 내시경 등의 순서로 진단적 접근을 시도하는 것이 원발병소를 찾는데 도움이 될 것으로 사료된다. We carried out a prospective study of the effectiveness of a diagnostic strategy in thirty consecutively seen patients who had skeletal metastasis. The diagnostic strategy consisted of the recording of a medical history, physical examination, routine laboratory analysis, plain radiography of the involved bone and chest, whole-body technetium-99m-phosphonate bone scintigraphy, abdominal ultrasound, computed tomography of the chest, abdomen and pelvis, fiberbronchoscopy and fibergastroscopy. After this evaluation, a biopsy of the most accessible osseous lesion was done in twenty four patients. On the basis of the our diagnostic strategy, we were able to identify the primary site of the malignant tumor in nineteen patients(63%). The laboratory values were non-specific in all patients. The history and physical examination revealed the occult primary site of the malignant tumor in one patient(3.3%) who had carcinoma of the breast. Plain radiographs of the chest established the diagnosis of carcinoma of the lung in three patients(9.9%). Computed tomography of the chest identified an additional three primary carcinoma of the lung(9.9%). Fiberbronchoscopy identified an additional one primary carcinoma of the lung(3.3%). Abdominal ultrasound established the diagnosis in three patients(9.9%). Computed tomography of the abdomen and pelvis established the diagnosis in four patients(13.2%). Fibergastroscopy established the diagnosis in two patients(6.6%). Examination of the biopsy tissue established the diagnosis in one patient(3.3%). So we recommend to perform plain radiographs of chest, abdominal ultrasound, chest C-T, abdomino-pelvic C-T, fiber-bronchoscopy, fibergastroscopy sequentially.

Malignant tumor of the pelvic bone has nonspecific symptom and it is not easily detected by physical examination or by radiologic study in early stage, because of its anatomical characteristics. Associated with their variety of disease entity, the treatment of malignant pelvic bone tumor is a problematic point. We have analysed 36 cases of malignant pelvic bone tumors diagnosed at the Severance hospital from 1968 to 1993 to provide a reference for diagnosis and treatment of the malignant pelvic bone tumors. We found that the chondrosarcoma(27.8%) and the osteogenic sarcoma(27.8%) were the most common type of pelvic bone malignancy, and then, in the order of incidence, there were Ewing's sarcoma(16.7%), malignant fibrous histiocytoma(11.1%). There were differences of the age distribution among each diseases and the average age was Ewing's sarcoma 20.5, osteogenic sarcoma 27.2, chondrosarcoma 40.0, malignant fibrous histiocytoma 64.8, respectively. Three of the 5 patients with low grade tumors survived(60%), whereas 3 of the 17 patients with high grade tumors survived(18%). The survival rate of the low grade malignant group was 60%, the high grade was 18%.

신규호,박홍준,김종민,한수봉,강응식,Shin, Kyoo-Ho,Park, Hong-Jun,Kim, Jong-Min,Hahn, Soo-Bong,Kang, Eung-Shick 대한근골격종양학회 2000 대한골관절종양학회지 Vol.6 No.2

목적 : 족부 및 족관절에 발생하는 종양은 다른 부위에 비해 그 발생 빈도가 낮으며, 특히 악성 종양은 매우 드물고 양성 종양으로 간과되는 경우도 있어 족부 및 족관절에 발생한 종양의 임상 양상에 대해 알아보고자 하였다. 대상 및 방법 : 1989년부터 1998년까지 10년 동안 족부 종양으로 진단받은 72명을 대상으로 조사를 시행하였다. 결과 : 남자가 40예, 여자가 32예였다. 양성 종양이 53예(74%)로, 연부 조직 종양이 30예, 골 종양이 23예였다. 악성 종양은 19예(26%)였으며, 연부조직 종양이 17예, 원발성 골종양이 1예, 전이성 골종양이 1예였다. 양성 종양은 연부 조직에서는 섬유종이, 골종양에서는 골연골종이 가장 많았다. 악성 종양은 악성 흑색종이 7예로 가장 많았다. 호발 부위는 양성종양의 경우 족지부, 악성 종양의 경우 발 뒤꿈치 부위였다. 악성 종양 19예 중 국소 재발은 3예, 원격 전이는 8예에서 발생하였다. 결론 : 악성 종양이 26%였으며 원격 전이가 42%로 높았다. 따라서, 족부 종양의 경우 악성의 가능성을 염두에 두고, 치료 시에 병리학적인 확진이 필수적이라 하겠다. Purpose : Tumors of the foot and ankle are uncommon compared with those arising in the other sites, and the malignant tumors are rare. We analyzed the data of patients who have been diagnosed as having a tumor of the foot and ankle. Materials and Methods : Between 1989 and 1998, we treated 72 patients and analyzed on their clinical characteristics retrospectively. Results : Fifty-three cases were benign. Included are 30 cases of soft tissue tumor and 23 cases of bone tumor. Malignant tumor was in 19 cases (26%), including 17 cases of soft tissue tumor, one cases of metastatic tumor. The most common benign tumor was fibroma in soft tissue and osteochondroma in bone. Malignant melanoma was the most common malignant tumor of the foot (7 cases). The predilection site for benign tumors was around toes while for the malignant tumor mostly arises in the heel. Among 19 malignant tumors, local recurrence developed in 3 cases and the distant metastasis occurred in 8 cases. Conclusion : The ratio of malignant tumor and metastasis was high. Therefore, when we faced with a tumor of the foot and ankle, the histopathologic confirmation is essential through biopsy before the definite initial treatment.

Alveolar soft part sarcoma, named by Christopherson in 1952, is a very rare soft tissue sarcoma. It reportedly accounts for 0.5 to 1.0% of all soft tissue sarcoma and no established treatment principle assists it. The relative lack of symptoms makes it easily overlooked and consequently early diagnosis is frequently impossible. Often, the metastasis to the lung or the brain is the first manifestation of the disease. In some cases wide excision is not performed because it is misdiagnosed as a benign tumor. Authors experienced 7 cases of alveolar soft part sarcoma in 20 years and found the ultimate prognosis grave and the treatment not promising. Therefore, the authors recommend the following; 1. Early diagnosis and early treatment are important for successful management of alveolar soft part sarcoma. 2. Preoperative incisional biopsy is necessary for pathologic diagnosis. 3. The recommended treatment modality is a combination of wide excision, chemotherapy and radiotherapy.

Metastatic cancer is the most common tumor of the skeleton. The prevalence of pathologic fracture may increase as patient survival is prolonged by improved cancer therapy. With recent advances in orthopaedic procedure and medical management of terminal cancer patients, it is generally agreed that aggressive treatment should be undertaken for patient with pathologic fracture secondary to metastatic disease, and a team approach should be utilized. The authors have reviewed twenty cases of pathologic fracture of the long bone due to metastatic tumor treated in the Department of Orthopedic Surgery, Yonsei University College of Medicine, from April 1989 to April 1994 and the following results were obtained. 1. The mean age at surgery was 58.4 years (ranged from 24years to 86years) and among 20 cases, 10 cases were male and the others were female. 2. The most frequent site of pathologic fracture in long bone is femur(15 cases, 75%), and followed by humerus(4 cases, 20%), tibia(1 case). 3. The frequently encountered primary tumors that metastases to long bone are those of the lung(7 cases, 35%), breast(4 cases, 20%), and prostate(2 cases, 10%). 4. The operative procedure was performed by resection of the tumor mass extensively, and we used polymethylmetacrylate for filling the dead space after resection, in all cases. 5. The mean survival period after operation is 9.2 months(ranged from 1 month to 4 years and 9 month). 6. The results of postoperative pain relief status were graded as fair to excellent in 17 cases(85%).

신규호,조용진,Shin, Kyoo-Ho,Cho, Yong-Jin 대한근골격종양학회 2012 대한골관절종양학회지 Vol.18 No.1

골내 결절종은 양성 낭종으로서 주로 관절 근처의 연골하골에 위치하며 점액성으로 변화된 섬유성 조직으로 구성되어 있다. 골내 결절종은 다양한 골격 부위에서 보고되고 있으며 경골 및 대퇴부의 원위부 등에서는 비교적 흔하게 발견되지만, 견갑골의 관절와에 위치한 골내 결절종 증례는 매우 드물며, 문헌 조사상 국외에서 14개 증례만 찾아볼 수 있다. 이에 본 교실에서는 견갑골의 관절와 골내 결절종에 대한 2예를 경험하여 문헌 고찰과 함께 보고하고자 한다. Intraosseous ganglion is a benign cystic lesion. It is composed of fibrous tissue with mucoid changes located in the subchondral bone adjacent to a joint. Intraosseous ganglion has been reported in various skeletal sites and most commonly in the lower end of the tibia and femur. However reports of intraosseous ganglion of the glenoid are rare, with only 14 cases in the literature. We repot 2 cases of intraosseous ganglion of the glenoid with literature reviews.

The heat and smoke which generated by subway under fire is one of the most harmful factor in air tighten underground station. To prevent this, Trackway Exhaust System(TES) can be used. The heat released from the train running in the tunnel raises the temperature at the platform and the trackway, and thus proper ventilation system is required for comfortable underground environment. When the fire is occurred, TES is operated as smoke exhaust mode from normal ventilation mode. In the present study, the subway station which is one of the line number 9 in Seoul subway is modeled, and fired situation is simulated with several ventilation mode of ventilation system in trackway. For this simulation whole station is modeled. Non steady state 3D simulation which considered train under fire is entering to the station is performed. Temperature and smoke distribution in platform and trackway are compared. To represent heat by fire, heat flux was given to the fired carriage, also to describe smoke by fire, concentration of CO is represented. As the result of present study, temperature and smoke distribution is different as the method of ventilation in trackway and platform is changed. In over side of trackway, the fan must be operated as exhaust mode for efficient elimination of heat and smoke, and supply mode of fan operation in under side shows better distribution of heat and smoke. The ventilation system which is changed from ventilation mode to exhaust mode can be applied to control heat and smoke under fire.
