The Corona virus has revealed a state of human weakness in facing it, and it has also revealed the absence of attention on the part of countries in the science of crisis management and the absence of strategic planning, and the weakness of strategic leaders in most countries of the world, and that the spread of this virus in the way we lived will inevitably affect the future of the world, and that the world is beyond Corona will inevitably not be the same as it was before Corona, and since the crisis is complex and intertwined, so its treatment must be a comprehensive and integrated treatment among the countries of the whole world, and the research aims to highlight the potential for the strategic leadership's contribution to managing the Corona crisis, and the research is talking about the future vision of a post-world Corona. Study design: Study design of article is descriptive study Results: This study found that leaders at the strategic level must develop insight, wisdom, and the ability to think outside the box and they must be able to relate and synthesize ideas, and that strategic leaders must have the ability to consciously sense opportunities that are distant - opportunities that are not clear to others -, and it includes Identifying such opportunities, the ability to explore and see what is unfamiliar, through a comprehensive view of the system, and this view must be reflected in their willingness to evaluate ideas in terms of their value to the system, not just their function, and to envision the features of the strategic leadership of the post-Covid-19 world.

Indoor environmental conditions in classrooms affect students' health and academic performance. studies have proven that the quality of the indoor environment is important in classrooms. Indoor environmental quality (IEQ) is represented in achieving thermal comfort, indoor air quality, visual comfort, as well as acoustic comfort. The research aims to determine the extent to which the shape and orientation of the classroom in Egypt affect the quality of its internal environment, and the thermal performance, as well as achieving good ventilation for the classroom. The research conducted an environmental simulation for the classroom in Cairo, Alexandria, and Aswan using the environmental simulation program Design Builder. To study the extent to which the design, shape and orientation of classroom openings in accordance with the design standards of the Educational Building Authority affect thermal comfort and air velocity in the classroom in selected study areas in Egypt. The model has been calibrated via field measurements in a standard classroom.The research found that the expected percentage of dissatisfaction (PPD) inside the classroom in Aswan is higher than the PPD for the classroom in Cairo by a rate exceedingly 40%. The predicted mean vote (PMV) for the classroom in Cairo is the best during the school months, as its ranges from zero to less than (+1 and -1). The classroom with the southern orientation in Alexandria represents the lowest in (PPD) in the school months from (December to May), as decreases by 20% compared to the classrooms in the other directions in Alexandria

Due to the increase in population and movement between cities, the number of flyovers has increased to facilitate the move between different areas in cities that led to high car traffic. As a result, carbon emissions and pollution have increased, affecting the air temperature and quality in urban areas. Therefore, this paper studies how to improve the environmental performance under the flyovers in cities. The research’s aim can be fulfilled through biophilic design that works on the vitality of urbanization and integration with nature, as it promotes green infrastructure. This paper deals with the study of flyovers, their characteristics, and the necessary criteria for obtaining effective areas below them, biophilic design for urbanization, and the principles and criteria for its use to improve environmental performance under the areas of flyovers, with an analysis of examples of effective handling of flyovers. The paper focuses on a case study at the areas under the flyovers in Alexandria Square in Tanta city and its analysis before and after the biophilic treatment using the environmental simulation program Envi-met. The proposed design can reduce the value of PMV by about 35% from its current state during the hours of solar presence to achieve thermal satisfaction.

This study aims to describe the implementation of character education at the madrasahs and integrated Islamic schools, namely at: SDIT Al-Ghazali, MIN 1 Palangka Raya, SMP-IT Al-Ghazali, MTsN 1 Palangka Raya, SMA-IT Hasanka and MAN Kapuas. The principals, teachers, parents and students were the research informants. Data were collected through participant observation, in-depth interview, and documentary study. The triangulation was used to check the trustworthiness of the data. The results showed that the implementation of discipline was by giving rewards and punishments according to school rules; honesty by using the Kantin Kejujuran and some CCTV, while hard work by using school assignments, group study and student work. Supporting and inhibiting factors include teachers, parents, students and the school environment. This finding confirms that schools have their own ways in applying character education based on each of their vision, need and condition. Any future research can be more directed at implementing character in Islamic madrasahs/schools, families, and communities so that they are able to provide role models and scientific treasures in this issue, considering that character is very important, especially in this age of character crisis among students.

Wind energy represents one of the most important renewable energy resources that can support electrical power systems. Behaviour of wind turbines following contingencies may deteriorate system stability. This requires an extensive analysis of the possible effect of wind energy on the entire power system performance. This paper investigates the effect of wind energy on power system dynamic response. This is achieved by replacing conventional generators gradually by wind turbine (WT). Also, the optimal location of WT has been determined by checking influence on steady state operation. In addition, the effect on total fuel cost is considered to determine the optimal location of WT. The IEEE 30-bus system is used during the study. The results indicate that the system stability is enhanced in most cases with integrating wind energy into power system. The results can provide a scope for future planning and expansion in electric power systems.

This paper introduces a method to improve the performance of power systems using demand side management to overcome the problems of increasing load demand. Defining suitable demand reduction levels can cause a significant enhancement for the entire network. Therefore, the sensitivity factors related to each load centre are defined to rank the load centres according to their priority. According to these factors, the best required load reduction can be obtained at each load centre. The recommended reduction level has to ensure overcoming the problems associated with the voltage profile and transmission lines overloading due to the increase in load demand. The IEEE 30 bus system is used to highlight the demand-side management strategy under different loading conditions. Some simulation results are introduced to show the importance of considering the sensitivity of load centres when defining the reduction levels at each load centre. The recommended demand side management is compared with the load shedding technique as an emergency action to avoid the problems of line violation and to keep the system stable and secure. According to the obtained results, considerable improvement is achieved in the voltage profile, the network efficiency and power loss without the need for the load shedding. These results encourage the implementation of the introduced technique considering sensitivity of load centres in smart grid environment
