Objectives: To demonstrate effective diagnostic method and proper management of recurrent thyroid cancer through to compare treatment and surveillance of I131 scanning detected recurrence and clinically detected recurrence. Material and Methods: We retrospectively analyzed clinical information about 46 patients who has recurrent thyroid cancer of 298 patients who have been primarily operated due to thyroid cancer in PMC at the over 10 years between 1986 and 1995. We examine incidence of recurrence due to pathologic types, site of recurrence, disease free interval, detection method of recurrence, and also treatment and progression of recurrence. A patients in which the clinical examination was entirely negative and the I131 scan demonstrated either a new area of I131 uptake or an increased area of concentration, compared to the previous scan, was designated as a recurrence detected by I 131scan only. Recurrences that were obviously by physical examination or chest x-ray, etc were considered clinically detected recurrence, regardless of the the results of the thyroid scan. Results: Mean of disease tree interval(DFI) is 36months. When mean DFI of I131 scan detected recurrence is 28months, whereas mean DFI of clinically detected recurrence is 47months. In statiscal analysis, p-value is 0.043 as significantly. In progression of recurrent patient, NED is 28case, AWD is Sease, DOD is 13case. Among the 13case, scan detected recurrence is lease of 20 patients(5%), whereas clinically detected recurrence is l2case of 26 patient(46%). In statiscal analysis, p-value is 0.003 as significantly. Conclusion: Early detection of the recurrent thyroid cancer by I 131 scanning leads to good progress compare with detection by clinical examination. NED: No Evidence of Disease AWD : Alive With Disease DOD : Dead Of Disease DOC: Dead of Other Cause

최근 건설산업에서 관리에 대한 중요성이 증대됨에 따라 포괄적 건설관리에 대한 필요성이 요구되고 있다. 이에 따라 본 연구에서는 건축 설계업무능력 향상을 위한 설계업무 프로세스 개선방안을 제시하는 것을 주목적으로 하였다 제시되는 의사결정 정보 흐름을 중심으로 한 설계업무 프로세스 개선방안은 건축 설계 시 각 참여팀 간의 원활한 의사소통과 정보의 추적 뿐 아니라 전체 프로세스에 대한 관리를 원활하게 하기 위한 기초 자료가 될 것으로 기대된다. 따라서 본 연구의 결과로 제시한 개선방향은 다음의 세 가지 요소로 된다. (1) 세분화되고 명확한 업무 정의, (2) 정보흐름 중심의 업무 정의, (3) 설계관리에 대한 업무 강화. As management is becoming a focus of a construction industry, conprehensive construction management is needed. Thus a plan of improving a design work process for developing design work capacity is proposed. The plan of improving a design work process based on a information flow for decision makings is expected to be a good ground material of not only smooth communication among stakeholders and information tracing, but also effective management of whole process.
