본 논문은 은행산업의 경쟁정도가 개별은행의 위험추구 성향에 미치는 영향을 파악하기 위한 실증분석을 수행하였다. 기존 연구에서 위험추구 성향을 나타내는 지표로 주로 사용하였던 고정이하여신비율은 위험을 사후적으로 반영하는 지표라는 점에서 한계점을 지니고 있는데 이에 본 연구에서는 위험을 사전적으로 측정하는 자산위험도를 새로운 위험추구의 지표로 제안하고 이를 이용하여 분석을 수행하였으며 그 결과 은행의 경쟁정도와 위험추구 성향 간에는 음의 관계가 존재함을 확인할 수 있었다. 한편 고정이하여신비율을 위험추구의 지표로 사용하여 동일한 분석을 수행한 경우에는 정반대의 결과가 나타나는 흥미로운 사실을 발견할 수 있었다. 즉 위험추구의 지표로 어떤 변수를 선택하는지에 따라 은행산업의 경쟁도와 위험추구의 관계는 정반대의 결과가 나타나고 있다는 것인데 이는 논리적으로 어떠한 지표가 은행의 위험추구 성향을 더 잘 나타낼 수 있는 것인가를 살펴봄으로써 해결할 수 있을 것이다. 자산위험도는 위험추구성향이라는 개념에 논리적으로 더욱 잘 부합하며 또한 위험추구성향 외의 요인에 의한 영향을 덜 받을 것이라는 측면에서 더 적절한 지표인 것으로 판단된다.

The hospital readmission rate has been widely used as an indicator of the quality of hospital care in many countries. However, the transferrability of this indicator that has been developed in a different health care system can be questioned. We reviewed what should be considered when using the risk-standardized readmission rate (RSRR) as a generic quality indicator in the Korean setting. We addressed the relationship between RSRR and the quality of hospital care, methodological aspects of RSRR, and use of RSRR for external purposes. These issues can influence the validity of the readmission rate as a generic quality indicator. Therefore RSRR should be used with care and further studies are needed to enhance the validity of the readmission rate indicator.

Community-based disaster preparedness approaches are increasingly important elements of vulnerability reduction and disaster strategies. They are associated with a policy trend that values the knowledge and capacities of local people. In this research, we describe the community diagnosis method and develop Flood Disaster Risk Reduction Index(FDRRI) for assessment of flood vulnerability. FDRRI is composed of four indicators such as Flood Exposure Indicator(FEI), Sensitivity Indicator(SI), Risk Reduction Indicator(RRI), and Community Preparedness Indicator(CPI). We anticipate to present the guideline for selection national preparedness projects and uplift community's preparedness capacity.

웹 어플리케이션의 작성에 많이 사용되는 ASP로 개발된 프로젝트에서 각 모듈의 위험수준을 분석할 수 있는 측정 도구를 개발하고 이 측정 도구를 실무에서 사용 중인 프로젝트에 적용하여 유용성을 보인다. 본 논문에서 개발된 측정 도구는 NASA의 GSFC에서 개발한 소프트웨어 산출물 품질 메트릭인 모듈위험수준 인디케이터(Indicator of the Module Risk Levels)를 사용한 것으로, 웹 어플리케이션의 위험수준을 파악하여 오류 가능성이 있는 위험한 모듈을 조기에 발견함으로서 유지보수성 향상에 기여하고자 한다.

The concept of improved performance indicators (PIs) for use in the KINS Safety Performance Indicator (SPI) program for reactor safety area is proposed in this paper. To achieve this, the recently developed PIs from the USNRC that use risk information were investigated, and a feasibility study for the application of these PIs in Korean NPPs was performed. The investigated PIs are Baseline Risk Index for Initiating Events (BRIIE), Unplanned Scrams with Complications (USwC), and Mitigating System Performance Index (MSPI). Moreover, the thresholds of the existing safety performance indicators of KINS were evaluated in consideration of the risk and regulatory response to different levels of licensee performance in the graded inspection program.

This paper develops a risk index based on an indicator of risk assessment in terms of coastal activity location and accident type. The risk index is derived from a formula which adds the consequence of failure to a vulnerability value, then subtracts the mitigation value. Specifically, the consequence of failure is the number of casualties in coastal activity locations. An indicator of vulnerability refers to coastal environment elements and social elements. A pointer of mitigation includes managerial and organizational elements that indicate the capabilities of coastal activities. A risk rating of coastal activity location is found from a risk matrix consisting of the accident location and type. The purpose of this study is to prevent accidents at coastal activity locations by allowing the Coastal police guard to monitor effectively and inform visitors of potential risks.

This study went beyond making an indicator simply based on theoretical arguments, and explored a wide spectrum of different types of perceptions about energy safety to make a concept of energy safety for the Korean society. The energy safety schemata of people can be divided into three types. Type1 is concern about multi-level risks-responsibility-centric, type2 is concern about security and personal burden-expertise-centric, and type3 is concern about health and personal burden-responsibility-centric. Questions were designed on the basis of the characteristics, differences and commonalities of the three types of perceptions, explored through the Q methodology, and Koreans' perception of nuclear safety was examined. Based on the results of this research the following components of trust in nuclear safety were derived, risk perception, responsibility, honesty, expertise and procedural justification. The items for specifically evaluating them were developed, and factor analysis was conducted, and as a result, the validity of each item was proven. The components of the nuclear safety trust indicator do not exist independently, but influence each other continuously through interactions. For this reason, rather than focusing on any one of them, laws and systems must be improved first so that they can move together in one big frame.

2015년 4월 개통한 호남고속철도 근처 노반의 침하 문제가 지속적으로 제기되고 있으며 이에 따라 호남고속철도 인근지역의 지반 안정성 또한 문제가 있을 수 있다. 위험지도를 제작하는데 있어서 지표 및 지표를 결정하는 인자를 선정하는 것은 매우 중요하다. 기존의 위험지표는 관측된 기간 중 가장 마지막 관측날을 기준으로한 최종 변위량으로 산정하는데 침하 원인과 지표의 거동을 분석하기 위해서는 시계열적인 지표변위를 확인해야한다. 또한 광범위한 지역의 경우 직접 수준측량을 실시하기에 경제적으로 비효율적이므로 SAR 영상을 이용해 지표변위를 관측하고자 하였다. 본 논문에서는 PS-InSAR기법을 이용해 시계열 지표변위를 관측하였으며 위험지표를 결정하기 위한 인자로 최종지표변위량, 누적지표변위량, 최소변위량과 최대변위량의 차를 이용해 각 인자로 위험도를 등급화하여 비교하였다. 그 결과 최종변위량의 위험도 등급과 각 인자 간 위험도 등급이 상이하였으며 위험지표를 결정하는데 있어 다양한 관점의 인자를 추가하는 것을 제안하였다. 이는 지반침하의 원인을 찾고 해결방안을 모색하는데 있어 중요한 연구가 될 것으로 기대한다.

Background: A comprehensive, traceable, and easy-to-understand radiation risk indicator is desired for radiological protection. The early-onset hypothesis could be used for this purpose. Materials and Methods: An indicator for early death (IED) was developed and calculated using the epidemiological dataset from the 14^th Report of the Life Span Study (LSS) of Hiroshima and Nagasaki. By clarifying the calculation process, IED for all-cause mortality was estimated. In addition, the characteristics of IED for solid cancer mortality and cardiovascular mortality as well as those of men and women, and their dependence on age at exposure were investigated for detailed analysis. Results and Discussion: The IED for all-cause mortality was estimated to be approximately 4 years for an acute radiation exposure of 1 Gy regardless of the fitting dose range. The cumulative death rate for all solid cancers also indicated the early-death tendency (approximately 7-10 years at 1 Gy). Although, there is a slight difference in the characteristics of the risk obtained from the LSS study and this study, it is considered that the IED in a unit of years can also be used to show the overall picture of risk due to radiation exposure. Conclusion: We developed and calculated the indicator for early death, IED, for the cumulative mortality rate of all causes of death, all solid cancers, and circulatory diseases. The quantitative values of IED were estimated to be 4 years for all causes of death, 7-10 years for all solid cancers. IED has an advantage for intuitively understanding the meaning of radiation risk since it can be obtained by a simple and traceable method.

The purpose of this paper is to highlight the impact of the performance of private wealth management (PWM) on the growth of retail banking in Indonesia. The variables used are bank's competitiveness, risk management, performance of private wealth management, and growth of retail banking business. The data were collected from 60 respondents from 32 banks over five months, from October 2018 to March 2019. Using partial least square path modeling, the analysis shows that the performance of private wealth management has an impact on the growth of retail banking sector in Indonesia. Bank competitiveness and risk management affect the performance of personal wealth management and have an impact on the growth of the retail banking business. Bank competitiveness is the variable that most influences the performance of private wealth management in Indonesia. This research found that market share is the most significant indicator of bank competitiveness. For risk management, significant indicators are the level of bank confidence, increased bank competitiveness, and the creation of new products. In the performance of the private wealth management variable, the most significant indicator is the revenue fee-based income. For the growth of retail banking business, a clear indicator is profit growth.
