Diagnosis with Chest X-Rays and other forms of medical images has soared to new heights as an alternative Covid-19, pneumonia, TB infection detector. Radiographic images, primarily X-Rays images play massive roles in assisting radiologists to detect and analyses severe medical conditions. Computer-Aided Diagnosis (CAD) systems are used successfully to detect diseases such as tuberculosis, pneumonia, covid-19 and other common diseases from chest X-ray images. The main objective of this study is to develop a model capable of detecting multiple diseases from chest X-rays, with the aim of assisting radiologists and other healthcare providers in making more informed and timely diagnoses. The proposed framework includes four main steps to identify various clinical states such as analysis of the chest X-Ray image dataset and dataset preprocessing, feature extraction, classification with machine and deep learning classifiers and building an ensemble method that can aid in the diagnosis of various diseases using image processing and artificial intelligence algorithms to quickly and accurately identify COVID-19, pneumonia, TB and other diseases from X-Rays to stop the rapid transmission of the virus. The authors obtained a training accuracy of 98% to 100% across all models.

As part of the studies conducted to investigate the career development of high school students. In this study, the researchers are interested in investigating the field of study aspired by students' higher school and associated contextual factors. Finding may be useful to design programs appropriate to help students in their vocational development. Participants were randomly selected from students' high school following their study in Azilal city Morocco. 75 students responded to the questionnaire, our sample consists of 24 men and 51 females with an average age of 17.91±1.09. Data collected were analyzed using descriptive and inferential statistical tests by SPSS 26.00 software. The results show the post-secondary education courses preferred by students and a significant rate of undecided. Results show that educational aspirations are formed based on students' interests and academic performance, and regional and international labor market conditions are also considered. The finding provides sociological information on the context of the shaping of educational aspirations in higher school.

 

Keywords: higher school, contextual factors, educational aspiration, field of study.

The administration at the municipal level and its management are the first governmental instance that receives and attends to the needs of the citizens, so it provides elements that should allow people to have a better quality of life, the present research establishes the objective of determining if the management elements evaluated in the municipalities and selects those that can present an alignment with the development of the population based on the Human Development Index results, present a positive relationship, for which a concurrent mixed methodology is used, which involves quantitative information obtained from statistics of official sources, and is analyzed with Spearman's rho statistic using the SPSS statistical program and, complementarily, the qualitative aspects are approached based on semi-structured interviews with management personnel of municipal administrations, researchers and academics from institutions of higher education, as well as state level officials with activities in municipal aspects. The main findings indicate that although there are correlations with average levels between economic development and income and health indexes, they are not notable in the well-being and improvement of citizens' conditions. The contributions of the interviews show that although the processes related to municipal planning, the alignment of public policies and the establishment of mechanisms for citizen participation have improved, the municipalities present challenges in terms of improving the well-being of the population.

 

Keywords: municipal management, human development, evaluation.

Radicalism is often associated with violent ideas and is considered to be a breeding ground for terrorism. This is because radicalism is an attitude that seeks a complete overhaul of established values and norms and often resorts to violence to achieve its goals. Meanwhile, some view counter-radicalism efforts as an authoritarian approach by the government and contrary to international human rights. The government is not targeting critical ideas but rather those inciting hatred, hostility and violence, leading to terror. In Indonesia, countering radicalism cannot rely solely on repressive measures, but preventive strategies should be implemented by identifying its perpetrators. This includes addressing radicalism in cyberspace, such as social media, where hate speech and incitement are often spread. Therefore, it is essential to have a rigorous assessment process to identify and evaluate potentially radical actions. This process measures the level of exposure to radicalism among those propagating radical content on social media, which determines whether they will attend a deradicalization Islamic boarding school or face the criminal justice system. In conclusion, this study ensures that measurable action is taken against the spread of radicalism on social media.

 

Keywords: assessment, radicalism, concept of countering, social media, Indonesia.

The viable system model (VSM) is a conceptual framework for analyzing and designing complex organizations, which was developed by Stafford Beer in the 1970s. It is based on the idea that every organization is a system composed of a set of interconnected subsystems that must work together effectively to achieve its goals. One of the key scientific novelties of using the VSM in technological issues is its emphasis on adaptability and resilience. The VSM recognizes that organizations must be able to adapt to changing environments and circumstances in order to survive and thrive, and that this requires a flexible and responsive organizational structure that is capable of learning and adapting over time. By using the VSM to design and manage their technological systems, organizations can create more adaptive and resilient systems that are better able to respond to changing technological and market conditions. The current dynamics of the market push companies to look for ways to improve their competitive position by relying on instruments that facilitate the effective acquisition, processing, and analysis of large amounts of data from different and dispersed sources; in response to this need, various tools for research and information processing have emerged. One of them is the technological observatories that appeared in the nineties. They are considered tools that assist in the design of strategies, the decision-making of companies, and the development of public policies. The following research aims to characterize a technological observatory for MSMEs in Mexico based on the model of viable systems (VSM); its intelligence area is validated through a prospective model for the next five years using the I Think 8.0 software. The methodological strategy is based on the mixed sequential explanatory method; in the first instance, a quantitative analysis is carried out on the structure, processes, human resources, and innovation of twenty technological observatories of the business sector that operate worldwide, after which a qualitative analysis was elaborated established in thematic axes on the opinion of experts in areas of public policy,  technologies, knowledge transfer, education, both contributions supported to generate an overview of the current state of technological observatories in Mexico and worldwide, then obtain the necessary inputs to develop the proposed model. As a result, an observatory model was obtained for MSMEs with good profitability and permanence over time, thanks to their anticipated strategies based on the perspective regarding their management.

 

Keywords: MSMEs, observatory, foresight, viable systems, competitiveness.
