  • Objectives: Slip and fall accidents in the workplace are one of the top causes of work related fatalities and injuries. Previous studies have indicated that fall risk was related to postural and dynamic stability. However, the usage of this theoretical relationship was limited by laboratory based measuring instruments. The current study proposed a new method for stability assessment by use of inertial measurement units (IMUs). Methods: Accelerations at different body parts were recorded by the IMUs. Postural and local dynamic stability was assessed from these measures and compared with that computed from the traditional method. Results: The results demonstrated: 1) significant differences between fall prone and healthy groups in IMU assessed dynamic stability; and 2) better power of discrimination with multi stability index assessed by IMUs. Conclusion: The findings can be utilized in the design of a portable screening or monitoring tool for fall risk assessment in various industrial settings.

  • Mombasa is the principle port of Kenya, serving inland countries in Eastern and central Africa. Mombasa port has undergone a massive infrastructure upgrade and dredging works with an expectation that more vessels and large post Panamax ships will be able to enter Mombasa port. Therefore, it is vital to carry out a marine traffic risk assessment in order to quantify the degree of navigation safety needed in the Mombasa approach channel and also to evaluate the navigation risk imposed on transit traffic by local ferry traffic. In this paper, a marine traffic risk assessment is carried out using the IWRAP mk2, Environmental Stress (ES) model, and the PARK model. Risk assessment results show that Likoni area has an unacceptable stress/risk ranking at 20.7% by the ES model and 38.89% by the PARK model. The IWRAP mk2 model shows that the crossing area has the highest risk of crossing collision and the area at the entrance to the inner channel has a high risk of grounding. The conclusions derived from this study will provide the basis for proposing the most effective countermeasure to improve navigation safety in the Mombasa approach channel.

  • Mombasa is the principle port of Kenya, serving hinter countries in Eastern and central Africa. Mombasa port has undergone a massive infrastructure upgrade and dredging works with an expectation that more vessels and large post Panamax ships will be able to call at Mombasa port. Therefore, it is vital to carry out a marine traffic risk assessment so as to quantify the degree of navigation safety on Mombasa approach channel and also to evaluate navigation risk imposed on transit traffic by local ferry traffic. In this paper marine traffic risk assessment is carried out using IWRAP mk2, Environmental Stress model, and PARK model. Risk assessment results show that Likoni area has unacceptable stress/ risk ranking at 20.7% on ES model and 38.89% by PARK model.

  • Background: Workplace violence (WPV) against healthcare workers (HCWs) employed in psychiatric inpatient wards is a serious occupational issue that involves both staff and patients; the consequences of WPV may include increased service costs and lower standards of care. The purpose of this review was to evaluate which topics have been focused on in the literature and which are new in approaching the concern of patient violence against HCWs employed in psychiatric inpatient wards, in the past 20 years. Methods: We searched for publications in PubMed and Web of Science using selected keywords. Each article was reviewed and categorized into one or more of the following four categories based on its subject matter: risk assessment, risk management, occurrence rates, and physical/nonphysical consequences. Results: Our search resulted in a total of 64 publications that matched our inclusion criteria. The topics discussed, in order of frequency (from highest to lowest), were as follows: "risk assessment," "risk management," "occurrence rates," and "physical/nonphysical consequences." Schizophrenia, young age, alcohol use, drug misuse, a history of violence, and hostile-dominant interpersonal styles were found to be the predictors of patients' violence. Conclusion: Risk assessment of violence by patients appeared the way to effectively minimize the occurrence of WPV and, consequently, to better protect mental HCWs. We found paucity of data regarding psychologic sequelae of WPV. According to these findings, we suggest the need to better investigate the psychologic consequences of WPV, with the aim of checking the effective interventions to assist HCW victims of violence and to prevent psychologic illness.

  • 영국은 2004년 국가재난관리법(Civil Contingencies Act 2004)을 통하여 "Emergency"라는 결과중심의 단일 재난개념을 확립하고 있으며, 이를 통하여 유형과 관계없이 다양한 위험에 대비/대응할 수 있는 시스템을 구축하고 있다. 역사적으로 볼 때는, 평시 재난관리체계와 민방위 체계가 서로 합쳐져 오늘날의 통합형 재난관리체계(Integrated Emergency Management)로 이어진 것이다. 영국의 재난관리체계는 지역단위에서의 대비 및 대응을 원칙으로 하고 있으며, 이를 위하여 각 대응기관 간의 상호협력과 정보공유를 강조하고 있다. 또한 지역사회 및 영국 전체에서 재난위험성을 진단하고 평가하는 제도, 즉 지역사회 위험목록(Community Risk Register) 및 국가위험목록(National Risk Register) 제도가 잘 구축되어 있으며, 그 평가결과 역시 국민들에게 공개되어 있다. 본 연구에서는 이러한 재난위험성 평가 제도를 비롯하여 영국 재난관리체계의 전체 특징 및 특히 최근 변화를 종합적으로 살펴보고, 이를 바탕으로 우리나라의 재난관리체계가 나갈 방향에 대한 정책적 함의를 도출하고자 하였다. 본 연구에서는 (1) (영국에서 기이 이루어진) 완전 통합형 재난관리체계의 도입 그리고 이에 따른 민방위 조직의 발전적 해체 및 단일 재난개념의 사용, (2) 경찰을 비롯한 각 긴급대응기관 간 상호운용성(Inter-operability) 확보를 위한 법제도 개선, (3) (영국의 지역사회 위험목록 및 국가위험목록과 같은) 지역 및 국가단위의 재난위험성을 평가할 수 있는 제도의 도입이라는 세 가지 정책적 함의를 제시해보았다.

  • 본해상교량 프로젝트의 설계단계에서 선박충돌 문제는 주로 교량 하부구조의 단면 결정에 관여하게 되며, 위험도 평가와 충돌 시뮬레이션 등을 통해 설계를 수행하게 된다. 선박의 충돌위험은 다양한 확률모델에 의해 평가되며 대체로 AASHTO Guide(2009)의 Method II와 유사하다. 그러나 해당기준에서 사용되는 일부 요소는 내륙수로에 국한되어 있거나 지역적인 요인이 강하여 설계자의 판단이 요구되므로 관련 기준이나 연구결과 등을 참고하여 결정해야 한다. 본 연구에서는 2010년 선박운항데이터를 사용하여 인천대교에 대한 위험도평가를 수행하고 기존 하부구조 및 방호구조물에 대한 위험도 및 내충돌 성능을 검토하였다. 그리고 AASHTO Guide의 Method II를 기준으로 하여 위험도평가에 필요한 요소들의 추정 방법과 적용 사례, 관련 연구결과에 대한 고찰을 수행하였다. 이로부터 위험도평가에 필요한 요소들의 적절한 가변영역을 정의하고 해당 구간에 대한 민감도 분석을 수행하였으며 설계단계에서 설계자가 주의하여 적용해야 하거나 지역적인 데이터의 직접 분석이 필요한 요소들이 확인되었다. 이번 연구는 해상교량에 대한 선박충돌을 고려한 설계시 위험도 분석과 관련하여 기본적인 참고자료가 될 것으로 판단된다.

  • The Istanbul Strait is one of the important waterways in the world. And its southern entrance has a highly congested local traffic. Till now there are several studies regarding how the Istanbul Strait is dangerous to navigate and how those dangers can be mitigated. But there is no study regarding local traffic which is posing great collision risk. In a certain traffic area, marine traffic safety assessment parameters are traffic volume, frequency of collision avoidance maneuver, traffic density, traffic flow and potential encounter, In this paper local traffic volume, traffic flow and potential encounter number of local traffic vessels and possibility of collision are investigated in order to find degree of danger at the southern entrance of the Istanbul Strait. Finally by utilizing those, risky areas are determined for southern entrance of the Istanbul Strait. Results have been compared to a previous study regarding risk analysis at congested areas of the Istanbul Strait (Aydogdu, 2006) and consistency of the results were presented.

  • This study aims to recognize damage indicators of typhoon and to develop damage function's indicators, using information derived from the actual loss of typhoon Maemi. As typhoons engender significant financial damage all over the world, governments and insurance companies, local or global, develop hurricane risk assessment models and use it in quantifying, avoiding, mitigating, or transferring the risks. For the reason, it is crucial to understand the importance of the risk assessment model for typhoons, and the importance of reflecting local vulnerabilities for more advanced evaluation. Although much previous research on the economic losses associated with natural disasters has identified the risk indicators that are indispensable, more comprehensive research addressing the relationship between vulnerability and economic loss are still called for. Hence this study utilizes and analyzes the actual loss record of the typhoon Maemi provided by insurance companies to fill such gaps. In this study, natural disaster indicators and basic building information indicators are used in order to generate the vulnerability functions; and the results and indicators suggest a practical approach to create the vulnerability functions for insurance companies and administrative tasks, while reflecting the financial loss and local vulnerability of the actual buildings.

  • The increasing variation in climatic conditions under climate change directly influences plant-microbe interactions. To account for as many variables as possible that may play critical roles in such interactions, the use of an integrated modeling approach is necessary. Here, we report for the first time a local impact assessment and adaptation study of future epidemics of kiwifruit bacterial blossom blight (KBB) in Jeonnam province, Korea, using an integrated modeling approach. This study included a series of models that integrated both the phenological responses of kiwifruit and the epidemiological responses of KBB to climatic factors with a 1 km resolution, under the RCP8.5 climate change scenario. Our results indicate that the area suitable for kiwifruit cultivation in Jeonnam province will increase and that the flowering date of kiwifruit will occur increasingly earlier, mainly due to the warming climate. Future epidemics of KBB during the predicted flowering periods were estimated using the Pss-KBB Risk Model over the predicted suitable cultivation regions, and we found location-specific, periodic outbreaks of KBB in the province through 2100. Here, we further suggest a potential, scientifically-informed, long-term adaptation strategy using a cultivar of kiwifruit with a different maturity period to relieve the pressures of future KBB risk. Our results clearly show one of the possible options for a local impact assessment and adaptation study using multiple models in an integrated way.
