An accreditation plan can improve an organizational facilities and services regarding patient care and provides quality improvement skills. In my case scenario, I conceptualized an idea about accreditation of private well-established health care setting. The Kurt Lewin's theory insights a framework of change at the accreditation level, which will be achieved by the application of the transformational leadership style. Transformational leadership style works as guider, motivator, collaborative and bind with sustain the change management mission. The accreditation requires an international standard of practices and high quality of patient care in an organization. The accreditation requirement is fulfilled in the context of organizational cultural and environmental values, beliefs and delivery of services. In the case scenario presented an idea by the reflection on its organizational change. The private health care organization had accreditation capabilities. All essential and standardized equipment and performing procedural guidelines and following protocols. Kurt Lewin's theory give directions to such these kind of organizations in the context of change at the level of accreditation.

The study of the localization of girls' secondary schools in Jeddah shows that the school map is both a diagnostic and perspective tool for school policies. It is also a tool for research, for measuring accessibility and thus for helping decision-makers in the education sector (Ministry of education, regional education directorates, etc.) insofar as it makes it possible to visualize the scenarios of educational facilities. Through the present study, we have developed a map showing the distribution of the girls' secondary schools in Jeddah. This map shows for some households a low accessibility to these schools. That has enabled us to propose facilities to reassure a certain equality of opportunity for access to secondary schools.

The performance of two R‐11‐charged integrated solar water heater collectors was investigated experimentally for forced and natural circulation water flows. The heat transfer from the refrigerant loop to the hot water storage tank took place through a condenser of novel design integrated within the collector frame. The effect of the condenser inclination on the system efficiency was remarkable for natural circulation water flow but had no significant effect for forced circulation flow. The difference in thermal response between the refrigerant and water loops caused buildup of stored energy in the condenser. This energy affected the buoyancy forces and generated flow pulsation that caused a harmonic‐like variation of the system efficiency. This effect vanished with forced water circulation flow. The system efficiency varied between 20 and 50% depending on the solar insolation.
