Ensuring the integrity of a country's infrastructure is necessary to protect surrounding communities in case of disaster. Embankment dam systems across the US are an essential component of infrastructure, referred to as lifeline structures. Embankment dams are crucial to the survival of life and if these structures were to fail, it is imperative that states be prepared. Southern California is particularly concerned with the stability of embankment dams due to the frequent seismic activity that occurs in the state. The purpose of this study was to create a numerical model of an existing embankment dam simulated under seismic loads using previously recorded data. The embankment dam that was studied in Los Angeles, California was outfitted with accelerometers provided by the California Strong Motion Instrumentation Program that have recorded strong motion data for decades and was processed by the Center for Engineering Strong Motion Data to be used in future engineering applications. The accelerometer data was then used to verify the numerical model that was created using finite element modeling software RS2. The results from this study showed Puddingstone Dam's simulated response was consistent with that experienced during previous earthquakes and therefore validated the predicted behavior from the numerical model. The study also identified areas of weakness and instability on the dam that posed the greatest risk for its failure. Following this study, the numerical model can now be used to predict the dam's response to future earthquakes, develop plans for its remediation, and for emergency response in case of disaster.

This paper examines the Chinese government's response to four epidemic crises, including COVID-19, and analyzes the similarities and differences in these responses. It argues that while the Chinese government learned from previous epidemics and improved its handling of subsequent outbreaks, a significant variation occurred during the COVID-19 pandemic, which had a detrimental impact globally. Existing scholarly research on China's epidemic responses has often been limited in scope, focusing on individual crises and neglecting the central-local government relationship in crisis decision-making. By adopting a comprehensive approach, this paper delves into the nuanced dynamics of China's responses to these epidemics. It highlights the variations in responses, attributing them to the Chinese government's fear of undermined legitimacy and its consideration of its international image. The government's recognition of the importance of public perception and trust, both domestically and globally, has shaped its crisis management strategies. Through a detailed analysis of these factors, this paper contributes to a deeper understanding of the variations observed in China's epidemic responses. It emphasizes the significance of the central-local government relationship and the government's international image in determining its actions during epidemics. Recognizing these factors can provide policymakers and researchers with insights to shape future epidemic response strategies and foster effective global health governance.

Climate change, rapid urbanization, and population concentration have led to a higher frequency and magnitude of disasters in the world. Recently, the occurrence of large-scale complex disasters, which are caused by a combination of natural disasters, man-made disasters, and social disasters, is increasing. In Korea, there are many case studies of damage prediction and response technology development for individual natural disasters, such as earthquakes, floods, and typhoons. On the other hand, the system basis for the efficient response and management of large-scale complex disasters is insufficient. Therefore, this study examined the representative cases of natural, social disasters, and related cases of domestic disaster response management systems. In addition, this paper proposes ways to improve the legal system for complex disaster management policies and establish a cooperation system between the ministries for an efficient response.

The actual complaint handling response of the company serves as an important success factor for the company to reduce defection rate of customers who have complaints. In this regard, this study sought to divide the company's complaint handling response into substantial compensation, favorable employee behavior and organizational procedures, empirically verify the effects of the customer's justice perception on trust and satisfaction, and thus to present the importance of the company's actual response. To this end, the data obtained from a survey of 210 customers who filed complaints directly to the company was analyzed using SPSS and AMOS. The research results can be summarized as follows. The compensation for customers with complaints has a significant effect on justice, and the favorable employee behavior also has a significant effect on justice. In addition, the organization procedures about handling complaints have a significant effect on justice. Especially the justice as justice perception was found to affect the future behaviors of customers such as trust and satisfaction. Based on these findings, this study presented implications and suggested future research.

Background: As prevention of coronavirus disease 2019 (COVID-19) transmission in healthcare settings has become a critical component in its effective management, COVID-19 specific infection prevention and control (IPC) guidelines were developed and implemented by numerous countries. Although largely based on the current evidence-base, guidelines show much heterogeneity, as they are influenced by respective health system capacities, epidemiological risk, and socioeconomic status. This study aims to analyze the variations and concurrences of these guidelines to draw policy implications for COVID-19 response and future guidelines development. Methods: The contents of the COVID-19 IPC guidelines were analyzed using the categories and codes developed based on "World Health Organization guidelines on core components." Data analysis involved reviewing, appraising and synthesizing data from guidelines, which were then arranged into categories and codes. Selection of countries was based on the country income level, availability of COVID-19 specific IPC guideline developed at a national or district level. Results: The guidelines particularly agreed on IPC measures regarding application of standard precautions and providing information to patients and visitors, monitoring and audit of IPC activities and staff illnesses, and management of built environment/equipments. The guidelines showed considerable differences in certain components, such as workplace safety measures and criteria for discontinuation of precautions. Several guidelines also contained unique features which enabled a more systematic response to COVID-19. Conclusion: The guidelines generally complied with the current evidence-based COVID-19 management but also revealed variances stemming from differences in local health system capacity. Several unique features should be considered for benchmark in future guidelines development.

An integrated platform for garment drape simulation system has been developed. In this system, garment patterns from conventional two-dimensional CAD systems can be assembled into a three-dimensional garment on a parametrically resizable realistic human body model. A fast and robust particle-based physical calculation engine has been developed for garment shape generation. Then a series of geometric and graphical techniques were applied to create realistic impressions on simulated garments. This system can be used as the rapid prototyping tool for garments in the future quick-response system.

The different result and response of the earthquakes, occurred consecutively at China and Japan in May and June. respectively, is suggestive of the importance of preparedness against earthquake disaster. We learned lesson, although indirect, that the earthquake early warning. earthquake-resistant design, and people's concepts on earthquake can greatly reduce the earthquake hazards. The more preparedness we have in present, the less hazards we will experience for future.
