It is estimated that 499 million new cases of curable STIs occur every year. The existence of more than one million reported cases of STIs annually in Iran shows that addressing this issue must be a priority for Iranian health authorities. While recognition of the importance of gender issues to reproductive health (RH) programs has grown significantly in the past several years, major challenges remain in implementing gender-sensitive programs. Gender mainstreaming in Iranian reproductive health program is a relatively new issue, so this study aims to explore gender sensitive STIs/HIV/AIDS prevention policies. Method: This study employed a qualitative research design. Participants were health managers, health policy makers and reproductive health providers. They were selected purposefully and then continued by snowball sampling method. 43 semi-structured in-depth interviews with 37 key informants were done. All the interviews were recorded and transcribed. The data were analyzed by content analysis method. Trustworthiness of the data was achieved by using credibility, trans-ferability and conformability. Results: Key informants clearly explained the gender sensitive STIs/ HIV/AIDS prevention policies in three main categories: 1) advocacy, 2) collaboration between different sectors and 3) community empowerment to gender sensitive STIs/HIV/AIDS prevention programs. Conclusion: Changing gender neural STIs/HIV/AIDS prevention policy to more complete gender sensitive policy needs advocacy, collaboration of sectors and community empowerment.展开更多

This research aims to elucidate the process of policy implementation at the national and regional levels, and to explain the obstacles of policy implementation. The method was qualitative study. The stakeholders were 88 people. The data were collected by in-depth interview and coded by a computer program. The policy was transferred from the national AIDS committee to the Department of Disease Control (DDC) and provincial level. This process was lacking budget support. The provincial AIDS committee was monitored by the provincial health office, cooperating with the central level. The major role was to transfer the policy to the school, Local Administration Organization (LAO) and associated organization. The activity was funded by provincial, global funds, and outside sources. In the community, the core activities were AIDS knowledge, establishing core youth groups, and building the network of AIDS. The obstacle at the national level was changing the policy process from one with a budget to one without budget. In the area of practice, the AIDS problem and the effects of the risk behavior in youth groups were slightly concerned.展开更多

The methodology consisted in surveys, focus groups and Delphi method to assess teachers’, students’ and parents’ dietary habits, followed by an intervention for parents, and a participative nutritional education intervention with information and communication technologies applied to teachers, with the purpose to transfer nutritional knowledge and habits to school children and their families. Qualitative results were measured in all the phases of the project with positive results, and quantitative results demonstrated significant changes in food knowledge and healthy dietary habits in parents, teachers and students, compared with the control groups, without changes in students’ nutritional status during the short period of the intervention. With the results, an integral school nutrition education model in healthy eating was developed with children, parents, teachers and support for school management. This model should be applied in the educational sector to address the problem of unhealthy diet and childhood obesity that affects Chile and the world.展开更多

The prevention policy promotes the major role of forest layout, for which it is necessary to build appropriate facilities such as reducing ignition and fire propagation risks near the borders of roads and tracks, creating forest tracks to allow firefighters to move safely through the forest during a fire, creating fuel breaks in order to divide up forests and limit the propagation of fire. Land-clearing along a forest track consists in creating discontinuity between the herbaceous stratum and the tree stratum by eliminating the shrubby stratum and cutting tree crowns. It avoids fire propagation by convection, and enables firefighters to deal with the fire in safety. The main difficulty for forest officers is to identify an optimized method to select appropriate tracks to clear, because it is impossible to clear all the tracks each year. Remote sensing tools would seem to be particularly useful for obtaining the best strategic and economic overview of forest tracks at departmental scale. This theme “land-clearing evaluation method” was selected as a target application for the images derived from the new Pleiades sensors: products and services required by end users. The objective of this work is to assess the real potentiality of such Very High Spatial Resolution (VHSR) imagery for land-clearing management. The methodology used consists in image classification and spatial analysis in order to extract land-clearing quality, and also evaluation of land-clearing quality based on field questionnaires validated through interactions with firefighters and rangers. The development of this methodology and its application to QuickBird images-used as Pleiades data simulations-successfully showed that VHSR Imagery is useful for preventing fire risk. It seems to be a good perspective for providing operational mapping services to help land-clearing management.展开更多

Policy initiatives aimed at eliminating stigma and discrimination of affected people would enable them to access health and social services, practice safe behaviors and thereby protect public health. However, this response was characterized by tensions between differing perceptions of public health and human rights and, with the advent of effective treatments, between those who regarded behavioral and biomedical interventions as competing, if not mutually exclusive, approaches. A central theme in all of these elements has been control: control of the virus, control of the behaviors of people affected, control of policy and control of rights. HIV infection is both a cause and a consequence of human rights abuses, but for many people these two aspects are compounded into the same lived predicament; a predicament over which many feel they should have control. The test-and-treat debates at the 2010 IAS Conference demonstrated this as presenters and participants openly clashed over proposals to implement what many see as coercive measures in settings where viral transmission and the public health/human rights collaboration might both be regarded as now "out of control". This paper will explore issues of control in the international HIV response and how authority, in the forms of law and justice, is contested in that response.展开更多

Many maintenance models have been developed for WTs’ maintenance planning, suchas corrective, preventive, and predictive maintenance. Due to communities’ dependence on WTs for electricityneeds, preventive maintenance is the most widely used method for maintenance scheduling. The downside tousing this approach is that preventive maintenance (PM) is often done in fixed intervals, which is inefficient. In thispaper, a more detailed maintenance plan for a 2 MW WT has been developed. The paper’s focus is to minimize aWT’s maintenance cost based on a WT’s reliability model. This study uses a two-layer optimization framework:Fibonacci and genetic algorithm. The first layer in the optimization method (Fibonacci) finds the optimal numberof PM required for the system. In the second layer, the optimal times for preventative maintenance and optimalcomponents to maintain have been determined to minimize maintenance costs. The Monte Carlo simulationestimates WT component failure times using their lifetime distributions from the reliability model. The estimatedfailure times are then used to determine the overall corrective and PM costs during the system’s lifetime. Finally,an optimal PM schedule is proposed for a 2 MW WT using the presented method. The method used in this papercan be expanded to a wind farm or similar engineering systems.展开更多

Assume that PM is perfect for unit 1 and only mechanical service for unit 2 in the model. PM activity is randomly performed according to a dynamic PM plan distributed in each implementation period. A replacement is determined based on the competing results of unplanned and planned replacements. The unplanned replacement is trigged by a catastrophic failure of unit 2, and the planned replacement is executed when the PM number reaches the threshold N. Through modeling and analysis, a solution algorithm for an optimal implementation period and the PM number is given, and optimal process and parametric sensitivity are provided by a numerical example. Results show that the implementation period should be decreased as soon as possible under the condition of meeting the needs of practice, which can increase mean operating time and decrease the long-run cost rate.展开更多

The aim of this paper is to provide an update on the new knowledge about OAE and to propose recommendations to the World Health Organization how to address this public health problem.Main text During the 2nd International Workshop on OAE held on 19-21 September, 2023, in Antwerp, Belgium, participants recognised OAE as a substantial yet neglected public health problem, particularly in areas of sub-Saharan Africa where onchocerciasis remains hyperendemic. Evidence from prospective population-based studies suggest that strengthening onchocerciasis elimination efforts leads to a significant reduction of OAE incidence. There is a need to validate an OAE case definition to estimate the burden of disease and identify onchocerciasis-endemic areas requiring intensification of onchocerciasis elimination programmes and integration of epilepsy care. It is expected that raising awareness about OAE will boost the population uptake of ivermectin. The implementation of a community-based epilepsy treatment programme offering free anti-seizure medications (ASMs) has shown high effectiveness in reducing the frequency of seizures and improving the overall quality of life of people with epilepsy.Conclusions To reduce OAE burden, enhanced collaboration between onchocerciasis and mental health programmes at community, national, and international levels is required. Urgent efforts are needed to ensure the uninterrupted provision of free ASMs in onchocerciasis-endemic areas. Furthermore, OAE should be included in the quantification of the onchocerciasis disease burden.展开更多
