The reliability optimization process in earthquake engineering requires that the expected present value of the total cost is minimized, including the initial cost as well as the damage costs caused by earthquakes, which include indirect costs. One of these costs is concerned with how much society is willing to invest for preserving human life. Ethical principles, on which to base the assessment of this cost, are presented and discussed in this work. Individual and social values are analyzed. Finally, an optimal seismic design coefficient with the results obtained is calculated for a site with low seismicity.

In the process of quantifying optimum seismic design parameters, the losses implying the failure of the system must be assessed. Intangibles such as human lives may lie among indirect losses. In this paper, we propose a model to calculate the value of the investment that society should be willing to make for saving lives. In order to do this, we analyze both individual and social problems. However, special treatment is given to the individual problem where the value of the life of a human being is inferred by what the person should be willing to pay or willing to accept to reduce the risk of dying. Due to the use of utility curves in the calculation of this kind of intangible, we pay special attention to shape and requirement conditions of these curves. We also pay attention when personal impact and legacies or bequests are considered in utility curves. The results are shown through some applications, especially in the computation of optimum seismic design coefficients at a low seismicity site.

Introduction: Breast cancer represents a pathology that generates catastrophic impact and has recently increased its incidence and survival due to timely diagnosis and treatment. Therefore, improving the quality of life of cancer survivors has become a priority, offering reconstructive procedures that reduce complications, costs, hospital stay, and optimize resources. Material and methods: 264 patients reconstructed with autologous tissue (TRAM flap and latissimus dorsi) and alloplastic (breast tissue expander—breast implant and direct breast implant) were included. Variables such as demographic, anthropometric, and histologic type were collected. Results: 62% were reconstructed through the use of alloplastics and 38% with autologous tissue. The risk factors related to a greater probability of immediate postoperative complications (surgical site infection, surgical wound dehiscence and reconstruction failure) were obesity (OR: 2.1, CI: 1.5 - 2.7), preoperative radiation (OR: 1.89, CI: 1.75 - 1.92), arterial hypertension (OR: 1.2), Diabetes Mellitus (OR: 1.78) and smoking (OR: 1.31). Conclusions: The reconstructive process is complex and influenced by patient factors, surgeon experience and the hospital center. However, when choosing the reconstructive strategy, risk factors present in each patient must be considered, since radiation and obesity present a greater probability of postoperative complications.
