Failures of super large projects like IT Upgrade of Shinhan Financial Group can be a heavy blow not only to the company but even to the national economy. Research on the practices of risk management in those projects will provide invaluable lessons, enhancing capabilities and chances of successfully executing mission critical projects of the companies and the national economy as a whole. This paper analyzes the risk management of the Core Systems Reconstruction which was the most critical component of IT Upgrade. The analysis covers risk management plans, and identification and evolution, and control and monitoring of risk factors. This study confirms the major results of previous research on risk management in Korea. However, the analysis found as well some discrepancies of practices from the previous research results. This research also tracked the trajectories of evolution of risk factors and management. In particular, in depth analysis of control and monitoring is the first research in Korea on the "management" of risks in IT projects. The result of this research is expected to be a useful guide for theory development and practices of risk management in the future.

Objective: Egg consumption has been suggested to increase the risk of colorectal and some other cancers. The present study summarized and quantified the current evidence relating dietary intake of eggs and prostate cancer. Materials and methods: Literature searches were conducted to identify peer-reviewed manuscripts published up to July 2012. Twenty manuscripts from nine cohort studies and 11 case-control studies were identified. Summary risk estimates with 95% confidence intervals (CIs) were calculated for case-control and cohort studies separately. Results: Neither the case-control not the cohort studies showed any association of prostate cancer incidence with egg consumption (case-control studies: odds ratio 1.09, 95% CI 0.86-1.31; cohort studies: relative risk 0.97, 95% CI 0.97-1.07). The results were consistent in subgroup analysis. Furthermore, no association was observed between egg consumption and prostate cancer-specific mortality. Conclusions: Our analyses provided no evidence of a significant influence of egg consumption on prostate cancer incidence and mortality. However, more studies, particularly large prospective studies, are needed.

위험분석과 내부통제평가는 조직 내 자산을 보호하기 위한 여러 보안관리 활동들 중 핵심적인 사항이다. 위험분석은 보호가 필요한 영역을 식별하는데 사용되는 활동인 반면, 내부통제평가는 현재의 내부통제시스템이 자산보호에 있어 만족할 수준인지를 확인하는데 사용되는 활동이다. 위험분석은 일반적으로 비인가된 사람으로부터의 비인가된 접근에 그 초점을 두고 있으며 인가된 사람으로부터의 잠재위협에는 상대적으로 적은 관심만을 가졌다. 부정행위에 대한 관심이 증가하는 현 상황에서는, 이들 위협들 또한 적절히 다루어져야 한다. 본 논문은 이 두 가지 활동을 비교하고 그 차이점을 논하는 것을 목적으로 한다.

The automatic train control (ATC) system development project for the Automated Guideway Transit (AGT) system has high technical risk because the system is unmanned train control system using wireless technology which was unprecedented in train control industry of Korea. To overcome the technical risk during concept design phase of the ATC system development project, the integrated product team(IPT) carried out a reverse and reengineering process using a systems engineering design model. The generic systems engineering process is incorporated in the both reverse and reengineering process. As a result of the systems engineering effort, the IPT has built top layer systems engineering design model of the ATC subsystem. The purpose of this paper is to deliver the reverse and reengineering process which was used to develop the systems engineering design model of ATC system using a computer aided systems engineering tool. This study also shows that the model based reverse and reengineering process can reduce the technical risk by identifying the differences of requirement, functional and physical architecture between a reference system and a target system.

To understand biosafety's current situation in laboratory animal research and risk factors affecting occupational health. Compliance surveys were conducted by questionnaire via Questionnaire Star (an application app on the Internet) in Chinese. Thirty-nine anonymous questionnaires were collected. The surveyed institution has established 24 types of ABSL (Animal Biosafety Laboratory) and biosafety management organizations and systems equipped with safety equipment. Our study also suggests that the principal of the laboratory establishment fails to perform supervision and inspection responsibilities, the inappropriate design of the animal biosafety laboratory, non-standardized personnel training and health management, non-strict waste management, and insufficient emergency management. The administrative department and work units should address certain safety and occupational health risks in laboratory animal research. The author proposes control strategies based on organizational guarantee, personnel management, emergency management, etc., to help prevent risks and ensure occupational health. Due to regional limitations and small sample size, the results may not be generalisable to all parts of the world. However, some of the key common issuesmay also be present in other regions, sowe believe that this research still has some relevance.

Purpose: This study was to investigate the relations and odds ratio between hs-CRP and the risk factors of metabolic syndrome according to glucose intolerance and diabetes among the residents of a rural community. Methods: The subjects include 1,968 adults aged from 40 to 70 who were divided into four groups and a diabetes group according to glucose intolerance to compare the relations and risk ratio between hs-CRP and the risk factors of metabolic syndrome. Results: The results reveal that the greater the subjects' glucose intolerance was, the higher their hs-CRP became and the more risk factors of metabolic syndrome they had. The impaired glucose tolerance group showed 1.7 times higher blood pressure than the control group. The diabetes group showed a high odds ratio with 2.3 times higher blood pressure, 2.2 times higher abdominal obesity, and 2.4 times higherW/Ht than the control group. And the odds ratio increased significantly by 1.7 times in the hs-CRP intermediate risk group and 2.5 times in the high risk group compared with the control group. Conclusion: Considering the study results, it is very important to monitor abdominal obesity, blood pressure and the intermediate and high risk group of hs-CRP in order to reduce the contraction of cardiovascular diseases.

The Formal Safety Assessment (FSA) is a structured and systematic methodology developed by the IMO, aimed at assessing the risk of vessels and recommending the method to control intolerable risks, thereby enhancing maritime safety, including protection of life, health, the marine environment and property, by using risk analysis and cost-benefit assessment. While the FSA has mostly been applied to merchant vessels, it has rarely been applied to a DP vessel, which is one of the special purpose vessels in the offshore industry. Furthermore, most of the FSA has been conducted so far by using the Fault Tree Analysis tool, even though there are many other risk analysis tools. This study carried out the FSA for safe operation of DP vessels by using the Bayesian network, under which conditional probability was examined. This study determined the frequency and severity of DP LOP incidents reported to the IMCA from 2001 to 2010, and obtained the Risk Index by applying the Bayesian network. Then, the Risk Control Options (RCOs) were identified through an expert brainstorming and DP vessel simulations. This study recommends duplication of PRS, regardless of the DP class and PRS type and DP system specific training. Finally, this study verified that the Bayesian network and DP simulator can also serve as an effective tool for FSA implementation.

The main goal of a case-control study is to learn the association between various risk factors and a primary outcome (e.g., disease status). Particularly recently, it is also quite common to perform secondary analyses of the case-control data in order to understand certain associations between the risk factors of the primary outcome. It has been repeatedly documented with case-control data, association studies of the risk factors that ignore the case-control sampling scheme can produce highly biased estimates of the population effects. In this article, we review the issues of the naive secondary analyses that do not account for the biased sampling scheme, and also the various methods that have been proposed to account for the case-control ascertainment. We additionally compare the results of many of the discussed methods in an example examining the association of a particular genetic variant with smoking behavior, where the data were obtained from a lung cancer case-control study.

Cloud computing is a distributed computing model that has lot of drawbacks and faces difficulties. Many new innovative and emerging techniques take advantage of its features. In this paper, we explore the security threats to and Risk Assessments for cloud computing, attack mitigation frameworks, and the risk-based dynamic access control for cloud computing. Common security threats to cloud computing have been explored and these threats are addressed through acceptable measures via governance and effective risk management using a tailored Security Risk Approach. Most existing Threat and Risk Assessment (TRA) schemes for cloud services use a converse thinking approach to develop theoretical solutions for minimizing the risk of security breaches at a minimal cost. In our study, we propose an improved Attack-Defense Tree mechanism designated as iADTree, for solving the TRA problem in cloud computing environments.

Most software projects inevitably involve various types and degrees of uncertainty. Without proper risk assessment and coordination, software projects can easily run out of control and consume significant additional resource. Thus, risk management techniques are critical issues to information system researchers. Previous empirical studies of U.S. software firms support the adoption of development standardization and user requirement analysis techniques in risk-based software project management. Using data collected from software projects developed in Korea during 1999-2000, we conduct a comparative study to determine how risk management strategies impact software product and process performance in countries with dissimilar IT capabilities. In addition, we offer an alternative conceptualization of residual performance risk. We show that the use of residual performance risk as an intervening variable is inappropriate in IT developing countries like Korea where the role of late stage risk control remedies are critical. A revised model is proposed that generates more reliable empirical implications for Korean software projects.
