Modular construction has benefits such as short construction duration and high productivity owing to the production in factory and owing tosimultaneous on-site work. However, rework occurs in modular construction and the rework affects the efficiency of modular construction. The almost of causes of rework are exist in design process. To reduce the cause of rework, the information flow of the design processshould be managed and the plan to reduce rework should be included. However, the modular construction has complex process because ofimpeded unit production so it is hard to manage the information flow in design process. Moreover, when the plan to reduce rework isincluded, the design process will be more complicated. Therefore, the objective of this research is to suggest the design process including therework reduction plan and to alleviate the complexity of design process by using Dependency Structure Matrix(DSM). By using DSM, theiteration and feedback in design process is reduced and it can be expected that rework in modular project can be reduced by using suggesteddesign process. 재시공은 모듈러 건축의 효율에 영향을 미치며, 대부분의 재시공 원인은 설계단계의 정보흐름의 오류로 인하여 발생한다. 재시공 감소를 위해서는 설계단계에서의 관리가 요구된다. 하지만 모듈러 건축 프로세스의 복잡성으로 인해 설계단계에서의 정보관리가 어려우며, 재시공감소를 위한 계획을 반영할 경우 복잡성을 증가하게 된다. 따라서 본 연구에서는 재시공을 줄이기 위한 계획을 포함한 설계프로세스를 제시하며, DSM을 활용하여 정보흐름의 복잡성을 감소하였다. 본 연구결과를 활용하여 모듈러 건축의 재시공을 줄일 수 있을 것으로 예상된다.
국내 주택시장 참여자의 거래의사 결정과정 및 시장 파급효과의 동태적 분석 - 금융위기 이후의 주택시장 침체원인 및 주택정책을 중심으로 -

2008년 글로벌 금융위기 이후 국내의 주택시장은 침체기를 겪고 있으며 이에 따라 주택가격의 하락, 임대주택가격의 상승등과 같은 주택시장의 문제점이 발생하였다. 주택시장의 정상화를 위해 정부에서는 다양한 주택정책을 발표하였으나 주택시장은 아직 회복세를 보이지 않고 있다. 따라서 본 연구는 주택시장의 침체 원인 분석하기 위해 주택 시장의 주요 참여자인 주택공급자와 주택 수요자를 기존의 수요 공급 원리에 의해서 분석하며 이들의 거래의사에 영향을 미치는 심리적 요인을 행동경제학 이론을 바탕으로 분석한다. 이의 분석 결과를 바탕으로 시스템다이내믹스 시뮬레이션 방법론을 사용하여 발표된 정책의 실효성을 검증한 결과 정책의 입안 기간에 따라 주택 거래량과 주택담보대출 총액이 영향을 받는 것으로 나타났다. After 2008 global financial crisis, Korean housing market has experienced stagnation. So it caused housing market problems like housing price reduction, rising rent cost and so on. For housing market normalization government announced policies but Korean housing market didn't recover from stagnation. So, to understand why Korean housing market couldn't overcome the recession and why the policies didn't be effective, this research analyzed housing market participants (home owner, housing demand) based on the law of supply and demand and the psychological effect on their transaction intention based on behavioral economics(behavioral finance). Based on the analysis this research tested the effectiveness of announced policies using System Dynamics. The result showed that the amount of transaction and mortgage loan was influenced by the length of time to draft policies.
OSC를 적용한 도심지 소규모 공공주택 공급 활성화를 위한 사업모델 - 다필지 분산형 소규모 공공주택 통합발주방안을 중심으로 -

Public housing providers are planning to supply using small-scale urban sites. However, the efficiency of the project is expected to decrease due to civil complaints during construction. In the OSC project, most of the construction work are conducted in a factory. Therefore, OSC can improve the efficiency of the project and also minimizes the impact on the environment. However, the supply method requires that the small construction company should have experience and knowledge of the OSC. In this study, the business model based on the integrated implementation of dispersed small-scale public housing construction projects was suggested to assist the small construction companies in accumulating OSC experience and to improve the efficiency of OSC project. Through applying the model, it is expected that the small construction company will be facilitated in accumulating the experience and knowledge of OSC and the small-scale OSC projects will be activated by the improved efficiency.

N/A Clinical observation was performed of 229 cases of acute cholecystitis who admitted to Department of Internal Medicine Korea University Hospital for 5 years from Jan. 1980 to Dec. 1984. The following results were obtained: 1) The total number of cases of acute cholecystitis was 229 which was 0.46% of total admission cases during the same period. 2) The age incidence was the highest in 6th decade. The ratio of male and female was 1: 1.3. 3) On admission the most common clinical symptom was pain in the R.U.Q. and epigastrium(75.5%), the remainders were fever(40.2%), chill(36.2%), indigestion (34.1%), and nausea with vomiting(28.0%) in order of frequency. 4) The most common physical finding was tenderness on the R.U.Q ((81. 2%), and the remainders were tenderness on the epigastrium(33. 6%), jaundice(27.l%), and fever with palpable liver(23.6%) in order of frequency. 5) Laboratory examination showed leukocytosis(45.4%), elevated E.S.R. (91.0%), elevated alkaline phosphatase(55.9%), and elevated serum total bilirubin(36.9%). 6) On the radiological examinations the gallstones were presented in 9.3% by plain abdomen. On the sonographic examination of abdomen gallbladder stones were noted in 54.2% common bile duct stone in 15.O%, and intrahepatic duct stone in 6.0% 7) The 46.3% percent were improved by the medical conservative treatment. The 49.8% percent were improved by the surgical treatment and the 1.7percent was expired. 8) The complications of acute cholecystitis were 3. 1 percent.

Tuberculosis of the pancreas is a rare disorder, little reported in the literature. It may not develop primarily within the pancreas, and may occur secondary to a focus elsewhere in the body. A 50-year-old woman presented with weight loss, epigastric pain and palpable abdominal mass. A diagnosi of inoperab]e carcinoma of the panceas was made after radiologic evaluation. But tubercu- losis of the pancreas was confirmed by sono guided fine needle aspiration biopsy. Completely recovery resulted following the admmistration of antituberculous chemotherapy.
