The Welfare Organization plays a crucial role in empowering its clients by providing opportunities for creating employment. Creating employment for people with disabilities is a key focus for the organization, as well as a priority for governments' social and welfare policies. Professional empowerment of people with disabilities involves gaining society's trust in their abilities, which is the ultimate goal of this process. This study aims to assess the effectiveness of the programs and activities of the General Welfare Department of Kermanshah province in establishing sustainable employment opportunities for people with disabilities.

This research used a qualitative approach for content analysis. The study included experts, managers, and clients, and in-depth interviews were conducted to collect information. The samples were purposefully selected.

The research findings revealed several factors that have impacted the effectiveness of welfare department programs and activities. These include centralized planning, programs not addressing the needs of the disabled, incorrect diagnosis of needy clients, lack of organizational cohesion in first step, providing facilities based on the needs, insufficient funds in second step, discrimination in service provision, inadequate cooperation from other organizations, lack of supervision over loan payments, and financial problems faced by clients in third step.

 The examination of experts, managers, and clients' statements and content suggests that the General Welfare Office's programs and activities have a moderately effective impact on creating sustainable employment.

Magnetic nanoparticles have attracted a lot of attention due to their unique chemical and physical properties and their use in medical applications such as hyperthermia. In this research, copper ferrite nanoparticles were synthesized by combustion gel-sol method. The synthesized samples were studied by X-ray diffraction (XRD), Fourier transform infrared (FTIR) spectroscopy, nitrogen adsorption and desorption test (BET), energy dispersive spectroscopy (EDS), scanning electron microscopy (FESEM) and vibrational sample magnetometry (VSM). The average crystal size was about 25 ± 8 nm and its specific surface area was about 2.59±0.20 m2/g. Morphology and shape of nanoparticles were spherical and the average size of copper ferrite nanoparticles was about 96 ± 10 nm. Copper ferrite has ferromagnetic properties and saturation magnet was obtained at about 29.28 emu/g. the release of ibuprofen from these nanoparticles was investigated. Cytotoxicity of the nanoparticles on HT29 cancer cells was evaluated. CuFe2O4 copper ferrite nanoparticles were also analyzed by hypothermia method. The results showed a rise in temperature to about 42 ° C and a specific adsorption rate of 9.62 W/g.

Nowadays due to the existence of the economic and geological uncertainties and the increasing use of scenario-based project evaluation in the design of open-pit mines, it is necessary to find an exact algorithm that can determine the ultimate pit limit in a short period of time. Determining the ultimate pit limit is an important optimization problem that is solved to define what will be eventually extracted from the ground, and directly impacts the mining costs, revenue, choosing mining equipment, and approximation of surface infrastructures outside the pit. This problem is solved in order to maximize the non-discounted profit under the precedence relation (access) constraints. In this paper, the Highest-Level Push-Relabel (HI-PR) implementation of the push–relabel algorithm is discussed and applied in order to solve the ultimate pit limit optimization problem. HI-PR uses the highest-label selection rule, global update, and gap heuristics to reduce the computations. The proposed algorithm is implemented to solve the ultimate pit limit for the nine real-life benchmark case study publicly available on the Minelib website. The results obtained show that the HI-PR algorithm can reach the optimum solution in a less computational time than the currently implemented algorithms. For the largest dataset, which includes 112687 blocks and 3,035,483 constraints, the average solution time in 100 runs of the algorithm is 4 s, while IBM CPLEX, as an exact solver, could not find any feasible solution in 24 hours. This speeding-up capability can significantly improve the current challenges in the real-time mine planning and reconciliation, where fast and reliable solutions are required.

An entrepreneurial city is a unified system, consisting of different elements designed and predicted accurately, and they work correctly together. There are two ways to identify these elements: the first way is the identification of elements based on entrepreneurs' and experts' ideas. Although this way gives precious information, because of not been tested in practice, it needs trial and error to achieve a successful entrepreneurial ecosystem. The other way is designing entrepreneurial ecosystem elements based on successful world ecosystems, and then, localizing the designed ecosystem according to every region's needs. Although this method needs some modifications over time, as is based on successful experiences, it may need less trial and error. This study aims to achieve entrepreneurial ecosystem elements by using the second approach. After selecting the four best entrepreneurial cities (Silicon Valley, New York, London, and Boston), the entrepreneurial ecosystem of these cities is studied through documentary study and qualitative content analysis. Then the elements are studied by a comparative study with the Boolean algebra method. Finally, two groups of elements are identified: the necessary components: economic and industrial architecture, culture, pioneer universities, entrepreneurship, and innovative governance; and contributing components: city infrastructure, pioneer organizations, and networking. In the next step, to rank the identified components, the TOPSIS method is used. Among contributing components, city infrastructure had the top score. All necessary components had the same score. This model can be used as a basis for designing an entrepreneurial city but may need localization for each region's needs.

Business model, how to production value, absorb customer, explain the structure of make money and cost, and all business on the way of this structure will be disparate and find identity. Now a day’s ،designing of the business model have known applicable in the four level: the product or services level, business unit level, company level and industry level. Whereas cities is the main center of economic activities, developing a business model is important. Add a new layer with name of the "urban layer" to the literature on the business model is the goal of this study. This research is of exploratory (qualitative) type and qualitative data were collected from the research method and with the method of data collection and documentary information as well as in-depth expert interviews. The nature of the research is inductive and the information obtained was analyzed by systematic review method, content analysis and logical analysis through MAXQDA software. The results show that the complex space of urban management, the need for economic policy and the facilitation of business affairs in the city, have necessitated the development of a business model for cities. In this study, after review and analysis, the dimensions of the extraction model and the relationships between them were explained, and finally the urban business model was designed.

Human resources are the backbone of the health system, and quality of work life is an important factor in maintaining and enhancing staff. In this study, we tried to identify and prioritize the effective factors in improving the quality of work life of employees. In order to adjust the factors derived from the sources and references related to the subject with the status of the organization under study, a consensus of experts was obtained in the form of a decision-making team (experts) comprising ten senior, middle, operational and hospital experts. Next, the importance of each of the components and indices was determined using AHP fuzzy group. The inconsistency for all tables was less than 0.1. After this step, the "assessment of the status quo" and the "ability to improve" were completed by the decision group. The face and content validity of this questionnaire were confirmed. Findings were analyzed using IPA-G-FGAHP method. In this study, 4 components and 20 indicators were evaluated. After determining the weight of these elements on the one hand and calculating their gap from the desired position on the other hand, by calculating the balanced gap, the priority of improvement was determined. Based on the findings, indicators of the existence of the insurance and pension system, equality and fairness of rights and benefits, health care and occupational safety benefits were ranked first to fourth, and suggestions were made.

Porous asphalt has a high proportion of air voids, which is a cause of low filler and grains, and higher coarseness. The benefits of this type of grain are decreased surface reflection, lower noise pollution, reduced splash and driving problems in rainy humid weather, and a greater skid resistance. This is clearly a very important consideration in accident reduction and improvement of road safety and integrity. However, conversely some mechanical features are degraded, such as the rutting resistance, which can be considered to be a weakness of this type of asphalt mixture. Based on previous studies, porous asphalt has been shown to have a low strength against rutting. There has been a wide range of studies conducted on using geotextiles in asphalt layers, but despite this its role in increasing the resistance to permanent deformation in porous asphalt has not yet been proved. In this research study, the effect of using geotextiles in the case of permanent deformation of porous asphalt samples was examined by applying the wheel track machine. It was observed at different temperatures and both dry and saturated conditions that geotextile-reinforced porous asphalt mixture can tolerate more loading cycles, with a decrease in the depth of the rutting.
