Lifelines are essential infrastructures and facilities that are considered vital to the rescue effort and recovery of the affected community in the event of a natural disaster or emergency. The lifeline systems in a densely populated area, such as the Los Angeles basin, are very complex. The Northridge earthquake, which occurred in southern California on January 17, 1994, caused extensive damage to many of these lifeline facilities in the epicentral area. Effects of the damages were felt not only in the vicinity area of the earthquake but also in areas far from the earthquake site. This paper describes the earthquake damage to and performance of gas and water distribution and electric power and telecommunication systems. The impact of these failures on the overall system performance are presented. The significance and effect of the interdependency of life systems in an integrated urban environment are discussed. Lessons learned on system performance, seismic risk, and reliability of lifeline systems from the Canadian perspective are presented. Key words: earthquake damages, electric power, gas, lifelines, performance, risk, telecommunication, water.

On March 11, 2011, Tokyo Electric Power Company’s Fukushima Daiichi Nuclear Power Plant (NPP) was hit by a tsunami caused by the Tohoku-Pacific Ocean Earthquake, resulting in nuclear accidents in Units #1 to #4. With the aim of improving the safety of NPPs worldwide, we summarize the lessons that have been learned following a thorough analysis of the event and make specific proposals for improving the safety of such facilities. The author has been involved in investigating the causes of the accidents and developing countermeasures for other NPPs in Japan as a member of the Committee for the Investigation of Nuclear Safety of the Atomic Energy Society of Japan [1], an advisory meeting member of NISA with regard to technical lessons learned from the Fukushima Daiichi NPP accidents, and a Safety Evaluation Member of NISA for the other NPPs in Japan [2].

With the increased use of multisite evaluation and implementation studies in health care, our team of evaluators reflects on our evaluation of a large-scale multiyear geriatric and extended care program implementation. We share lessons from conducting multiple rounds of data collection, analyses, and reporting. We also identify some key factors that can facilitate or hinder multisite evaluation efforts involving programs with different models of implementation. This article strives to improve the quality of large-scale evaluations of health programs implementation. Knowledge gained from this complex evaluation will inform public health programs funders, implementers, and key program staff to better plan for, engage in, and benefit from effective complex evaluations to promote health in diverse settings.

The role of nuclear energy is to supply electric power on a stable basis to meet increasing demands, reduce carbon dioxide emissions, and maintain stable electric power costs while ensuring safety. The Fukushima accident taught us many lessons for creating safer nuclear power plants. Considering the design of systems, the areas of weakness at the Fukushima nuclear power plants can be divided into three categories: plant protection, electricity supply, and cooling of the nuclear fuel. In this paper, focusing on these three areas, the lessons learned are proposed and applied for pressurized heavy water reactors. Firstly, hard protection against external risks ensures the integrity of components and systems such that they can perform their original functions. Secondly, additional emergency power supply systems for electrical redundancy and diversity can improve the response capabilities for an accident by increasing the availability of active components. Thirdly, cooling for removing decay heat can be augmented by adopting diverse safety systems derived from other types of reactors. This study is expected to contribute to the safety enhancement of pressurized heavy water reactors by applying design changes based on the lessons learned from the Fukushima accident.
