Previous construction failure researches were focused on the utilization plan based on failure information and development of failure classification. However, it has limitation to set up the plan for prevention of construction failure due to the lack of the number of on-site staffs. In order to prevent effectively construction failure, a prevention plan should be established through quantitative evaluation of failure causes. The purpose of this study is to suggest the assessment method for selection Critical Management Factor(CMF) and to analyze the CMF on the apartment structural framework using FMEA(Failure Mode and Effective Analysis) which is one of the methods of quantitative evaluation. The element of risk evaluation separated degree of failure risk and prevention respectively. The assessment method for selection of CMF can be utilized for planning proactive solutions on the failure, and it can be also selected critical factors about each project phases, type of facility and construction work.

In order to encourage construction practitioners to acknowledge failures and disseminate the information, the failure information must be documented and accumulated with a well-structured format, which contains not only the fact and result but also the circumstance and cause of the failure. In the Korean construction industry, many failures are not explained clearly and often not even reported publicly, partly because due to the lack of understanding positive aspects of failures, which can improve construction practices as a result of learning from failures. The purpose of this study is to develop a web-based construction failure information system using the case-based reasoning techniques, which can systematically accumulate, manage, and share the valuable failure information using a structured failure cases database. It can be utilized for planning proactive solutions on future failures by searching the very similar past failure cases.

Although Construction Failure Information has been reported in literatures, reports of research, and etc., it Is difficult to utilize the information because the information classification does not exist. Therefore, this study investigated and analyzed literatures of domestic and abroad research Institutions and suggested the Construction Failure Information Classification(CFIC). The CFIC is composed of four classified items; facility general information, failure situation information, failure cause Information, and failure counterplan information. Each item is divided sub-items. Through CFIC, Construction Failure Information can be standardized and utilized for useful data to prevent recurrences of construction failure.

Although the disaster management of Korea such as mitigation of disasters, preparedness for them and recovery from them. It should be considered based on the failures of the disaster management and the past experimental knowledge, it is believed that the repetitive occurrence of similar disasters is caused by absence of learning of disaster management organizational. That is, non-learning of the management organs due to experimental errors indicates that the organization themselves are not able to adjust to environment and the same kinds of disasters may happen in the future. Therefore, this study identifies repetitive failures by analysing reasons of the failures in terms of organizational learning in order to prevent from repetition of similar failures, and presents suggestions on the policy of disaster management. For the purposes, it carries both bibliographical analysis and case analysis. this study targets Daegu Subway Fire in 2003.

According to COSO(2013) "Internal control is a process that is designed to provide reasonable assurance that a firm can achieve its objectives, where differing aspects of internal control can be partitioned into operating objectives, reporting objectives, and compliance objectives." Internal control over financial reporting(ICFR) is focus on reporting objectives and includes that provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use or disposition of the company's assets that could have a material effect on the financial statements. Thus, firms with weak ICFR have negative a effect on Firm value because those firms are great likelihood of misappropriation and inefficiency decision. In this regard, this study investigates the association of ICFR with the likelihood of firm failure. Specially, I measure the characteristic of ICFR as disclosures of material weaknesses and operating personnel of ICFR. I identify the likelihood of firm failure as going-concern opinion issued in audit report. As result, I find that a higher probability of firm failure is positively associated with the material weakness in ICFR also I find that a higher probability of firm failure is negatively associated with experience and qualified CPA of personnel in ICFR.

The construction failures can be decreased by continuously improving the construction process based upon the information of construction failures. Herein, the information of construction failures can be utilized as the key factor far identifying the ineffective process and providing the improved construction process that can prevent failures. The objective of this research is to suggest a model for improving construction process continuously by using the information of construction failures. An extended review and analysis of literatures related to the construction failure are performed to investigate the definition, type, cause, and lesson teamed of failure. This research also identifies that process modeling methodology and case-based reasoning are applicable to the construction process improvement, and then it suggests a framework of CIMCP(continuous improvement model of construction process based on the module of case-based reasoning such as case retrieval, case index, and case adaptation.

This paper introduces a new teehniquc for reducing the compulsory misses of software-managed TLBs by prefetching necessary TLB entries before being used. This technique is not inherently limited to specific applications. The key of this scheme is to perform the prefetch operations to update the TLB entries before first accesses so that TLB misses can be avoided. For the identifications of the prefctch pages, the new classification is introduced, which is based 0n the view of an object code execution. Then, the algorithms and the implementation technique arc described. Using a quantitative analysis, the proposed scheme is evaluated to prove that it is a useful technique for the perronnall~~ ~nhan~"ment of the S/W managed TLBs. in addition, it is discussed that reducing the miss rate by the prefeteh scheme reduces the total miss penalty and bus traffics in S/W-managed TLBs.

지난 연재를 통하여 정보시스템 프로젝트의 성공적인 관리를 위한 성공요인과 실패요인, 그리고 관리요소와 프로젝트 관리 프로세스에 대해 살펴보았고, 이제 우리는 과거의 실사례를 되짚어 읽어 봄을 통해 반면교사(反面敎辭)하는 기회를 가져보고자 한다. 본 고에서 제시된 사례들은 저자들이 실제 가까이에서 경험한 것들도 있고 이미 널리 알려진 사례들도 있으나, 지금까지 제시한 성공 및 실패요인과 관리요소, 그리고 프로세스 관점에 따라 재해석해 보는 기회를 가져보는 것도 의미가 있다고 하겠다.
