The approach is to implement primary prevention and secondary prevention activity to increase knowledge and skills of the clients and their families of how to prevent and control type 2 diabetes through a wellness program in the clinic. The practicum began January 2015 and ended April 2015. 53 food bank recipients (non-diabetic and diabetic) were recruited. A quasi-experimental study design, pre-test/posttest, was used for the study. The impact of the program targeted diverse audience, high risk ethnic groups, and improved knowledge, awareness, management, and positive behavioral change. The study implication for public health promotion specialists is to narrow venues targeting the most vulnerable populations to promote and reduce type 2 diabetes.展开更多

Compared with the standard dynamic programming algorithm, this method restricts the searching range during layer matching. It can not only avoid possible mismatching between sample and target layer, but also reduce the time spent on layer correlation. The result of applying the improved methods on the data processed by standard method before indicates that the improved one is more effective and timesaving for the multi-well correlation system than conventional dynamic programming algorithm.展开更多

Usually the wells placement problem is tackled through the combined efforts of many teams using conventional approaches, which include gathering seismic data, conducting real-time surveys, and performing production interpretations in order to define the sweet spots. This work considers one formulation of the wells placement problem in heterogeneous reservoirs with constraints on inter-well spacing. The performance of three different types of algorithms for optimizing the well placement problem is compared. These three techniques are: genetic algorithm, simulated annealing, and mixed integer programming (IP). Example case studies show that integer programming is the best approach in terms of reaching the global optimum. However, in many cases, the other approaches can often reach a close to optimal solution with much more computational efficiency.展开更多

A popular approach to WPP is Genetic Algorithms (GA). Alternatively, WPP has been approached in the literature through Mathematical Optimization. Here, we conduct a computational study of both methods and compare their solutions and performance. Our results indicate that, while GA can provide near-optimal solutions to instances of WPP, typically Mathematical Optimization provides better solutions within less computational time.展开更多

As such, there is a necessity to engage adolescents in planning and decision-making processes that will affect their future health. This paper describes the need for more innovative and transversal actions, starting from the utility of a multidisciplinary and systemic approach to health. One way in which this can be achieved is by shifting adolescent health programs (AHPs) from a clinically oriented to an education-based model. In particular, AHPs need to consider a personalized and systemic approach to the well-being of adolescents in order to potentiate their strengths and improve weaknesses, enhancing self-esteem, empowerment, and resilience. This is in line with the complexity of human physiology and psychology, as well as scientific evidence showing that several factors significantly influence health status including lifestyle, social context, emotional experiences, and cognitive skills, as demonstrated by the AVATAR Project (“A new purpose for promotion and eVAluation of healTh and well-being Among healthy teenageRs”). This project—which provides a new framework for AHPs—was carried out in Italy and enrolled healthy students as subjects, and aimed to promote well-being in adolescents using a systemic and multistake-holder approach that involved creating a network composed of the different figures and environments around adolescents and moving toward a more school-based and student-centered approach to adolescent health education.展开更多
