URBAN VOIDS AS POTENTIOAL RESOURCES FOR THE CITY DEVELOPMENT
Recently, many cities suffer from urban development problems due to rapid urbanization, population growth and economic crisis which affect quality of life in the city. On the other hand there are many urban voids in these cities that formed because of many natural, historical, and economic factors. These unused urban voids introduce complicated negative impacts on the communities and the urban fabric that it exists in. Despite of the negative effect of the urban voids on the city, it provides great opportunities for urban development and considered as potential resources for redevelopment the city. It can achieve by utilizing the urban voids by programs of reuse that integrated with the development objectives of the city. The research aims to understand the meaning of urban voids and its formations and highlight the importance of the urban voids as potential resources for development the city. The research also determines the urban voids values which are identified as; environmental value, social value, economic value, historical cultural value and aesthetic value. Also, through the theoretical study and the lessons learned from analysis international examples, the research develops a framework to help planners and designers to improve the ways of re-using urban voids to maximize their utilization. The research concludes that the urban voids should be well managed to maximize its effectiveness and decrease any negative effect. In addition, effective re-use of urban voids requires integrate these voids as a part of the urban fabric and cooperation between all stakeholders who involved in the development process.

THE CONCEPT OF SMART CITY AS A DRIVER FOR THE URBAN TRANSFORMATION OF EGYPTIAN CITIES TOWARDS SUSTAINABILITY: OPPORTUNITIES AND CHALLENGES
At the next decade, an expected urban acceleration will occur in Egypt. The urban population will be increased by 34% more than 2006 ratio. Demographic pressures, rapid urbanization lead to more issues. While cities are growing rapidly in population, their development model is quite different from the Sustainable model. Egypt's 2030 vision for sustainable development has defined the future of Egyptian cities. The urban economy would be grown in more competitive and diversified manner. Therefore, an urban transformation should be taking place to induce the desired sustainable urban development. Our urban areas are in an urgent need for an advanced governance that is able to improve the socio-economical and environmental sustainability. At recent decades, policy-makers and academics, either in developed or developing countries, have focused on smart city concept. ICT addresses challenges and problems related to resource management, sustainable development, climate change, quality of life and improved performance of the city as a whole. This route will present the concept of the Smart City as a radical solution to many urban issues. Such concept is considerd as a revolution in the design and management of urban areas. This paper developped guidelines to manage the urban transformation of Egyptian cities with the drive of Smart City concept to help decision-makers and city managers to prioritize and to develop strategies to achieve the smart and sustainable development of existing Egyptian cities. The study depended on the inductive approach to define the concept of smart sustainable city and related information and concepts. literature review as well as a case study analysis were the methodology to reveal success's factors of urban transformation towards smartness to achieve the desired sustainable urban development. To deduce most important opportunities and challenges as well as to conclud guidelinese, the mental syllogistic reasoning approach was used. The study concluded that urban transition of Egyptian cities towards smartness is possible but its roadmap has many obstacles and challenges. The efforts of all decision makers, governors. academics and stakeholders have to be integrated to suggest and embrace our own initiative smart sustainable city as a prompt and costly-effective solution towards sustainability. This critical situation demand a self evolution and reconstructuring for municiplities - the key actor. municiplities have to launch smart applications and encourage the participation of all stakholders, in developing goals, priorities, plans, policies, strategies and actions. Municiplities have to look for ingenious ideas to financ the smart city’s intiatives.

COMPARATIVE ANALYSES OF COMPUTATIONAL IMPLEMENTATIONS FOR HEALTHCARE BUILDING DESIGN
Recently, the automation of architectural design process has been focused specifically in Healthcare buildings (HCB) for easier implementation and faster feedback. Hence, a great evolution of Computational Implementations (CIs) were appeared and studied for early stages of design process of HCB, such as generating design solutions, evaluation of design solutions or others to provide helpful tools for designers. This paper provides comparative analyses of a set of CIs that can be applied on different architectural design stages in HCB, these stages includes: a) architectural programming and topological diagram, b) generating design alternatives and c) evaluation of design solutions. The focused CIs in this study have been classified to computational tools, computational algorithms, computational approaches and hybrid methods; they are compared using a set of criteria with various evaluation methods. This comparative analysis helps designers to determine the appropriate CI or CIs’ combinations for each main early stage of HCB design, and also the possibilities of connecting two of the studied CIs in a framework to get wider outcomes were studied. The main study findings are the capabilities, limitation and features of each CI, in addition to the best selections in each early stage for different HCB design cases. Also, possible connections between different CIs were discussed on simple examples as a fruitful outcome of analyzing CIs’ combinations.

PROCESSES OF ACHIEVING URBAN RESILINCE ACCORDING TO MANUSCRIPTS OF THE UNITED NATIONS
The rate of urban expanding in countries of the world is vast increasing causing many risks and unexpected changes to the cities and urban systems. Accordingly, the interests in designing, planning and managing Cities had increased to cope with the challenges and promote the ability of urban systems to survive, adapt and growth. Urban resilience and the ability to withstand are the main factors of this conversion. As the urban resilience is unseparated part of “sustainable urban development” in the environmental, economical and social fields, so the United Nations has taken the burden of widely publishing the concept of “urban resilience and the ability to withstand “,it signed agreements and organized series of programs and conferences like Sendai. Due to the steady increase in the urbanism projects in Egypt is without resilient planning and management. So the research aims to take advantage of the United Nations indicators that applied the concept of urban resilience in urban development strategies to enhance the resilience of Egyptian cities.The research was based on the construction of a comprehensive theoretical framework through the review and study of literature on the subject of urban resilience and the ability to withstand through the United Nations theses and the organizations that follow their approach and support urban resilience, then the research analyze some experiments that included the concept of resilience in the planning and management of urban development at all levels. In an attempt to devise processes within which to achive urban resilience includes the overall results of the search and recommendations that can be relied upon in the case of Egyptian cities.The study aims to formulate processes for taking advantage of the United Nations indicators that applied the concept of urban resilience to enhance the resilience of Egyptian cities by integrating the basic aspects of urban resilience in the planning and management of cities to cope with the challenges and promote the resilience of urban systems and increase their ability to survive, adapt and growth whatever the type of chronic pressures and severe shocks it faces.

TECHNOLOGY DEVELOPMENT AND IMPLEMENTATION OF CONSTRUCTION IN THE DIGITAL AGE
The role of Digital Computer Aided Design (CAD) has been demonstrated by its ability to create three-dimensional forms of buildings and to analyze how this building is implemented, thus helping architects to design diversity and innovation and providing them with the ideas and possibilities they dreamed of before the digital age. Leads to the emerge of new methods of design that are more liberal and developing, as well as the emerge of new theories that control the sources of creativity of architects such as Parametric Designs, Algorithms Designs and other theories Modern. Because of this development process, the Computer Aided Manufacturing (CAM) has been used as an outlet for architects to implement and manufacture these infinite creativities, allowing them to construct vari-ous building elements such as cladding and structural elements in a digital manner using appropriate software and machines. The use of digital processing in architecture is a relatively recent phenome-non. As for the raise of modern programs and their expansion as well as the evolution of manufac-turing methods than ever before, Digital manufacturing comes to bridge the gap between design and implementation. Digital manufacturing used to produce and build fully complex Buildings. At this research we will deal with the strategies and processes for digital manufacturing, its uses, and final-ly the technologies and devices used in it. Also, we will deal with its importance in non-traditional projects and thus the impossibilities of implementing them in a traditional way. Showing that this process depends on computer -based system to allow digitally controlled translation of data from the design process to the manufacturing process, allowing the architect unlimited creative space that cannot be envisioned or manufactured in traditional ways. Thus, digital manufacturing became one of the most important possibilities that the architect had to arm to produce distinctive buildings.

THE CASE STUDY OF TAL AL-AKRAB (AL-SAYEDA ZEINAB PARTERRE)
The development of human behavior patterns is an important social aspect that contributes in finding solutions to many of the problems caused by slums, and each slum area has some of the values and characteristics that distinguish it from other regions, since it is possible to maximize those values and exploit them optimally In solving their problems, and although there are some positive behaviors, there are also some negative behaviors among slum dwellers which need to know their reasons of existence and the relentless attempt to help the inhabitants of these areas to overcome them, and work to develop their positive behaviors, which contributes significantly in Overcoming many of the problems caused by the phenomenon of slums.The aim of this research is to analyze study and compare one of the existing slums, and one of the new areas created for slum dwellers, to extract the underlying human values, both positive and negative, in order to maximize interest and avoid negatives when creating new areas for them. This is known as the approach of modifying behavior that will be mentioned in the approaches dealing with the slums and to achieve their psychological and social needs, in parallel with the environmental and physical needs.

EFFECT OF DIFFERENT WINDOWS’ GLAZING TYPES ON ENERGY CONSUMPTION OF A RESIDENTIAL BUILDING IN A HOT-ARID CLIMATE “Case Study: Residential Building in New Cairo City”
The increasing energy consumption of residential buildings in Egypt which reached about 42% of total energy consumption in latest energy statistics, affirms the need for energy conscious design of buildings. Many researches aim at guiding new buildings design to be energy-efficient, however, retrofitting existing buildings can result in significant reductions in energy consumption. This paper outlined different window glass types led to a reduction in cooling loads via the building envelope for the existing building. This paper aims to evaluate the effect of changing windows glass types to reduce energy consumption in the hot arid climate of greater Cairo. The energy analysis carried out by employing advanced simulation via DesignBuilder software for a residential building located in Cairo; this case study analyzed the performance of seven different window glass types in a residential building façade in the different cardinal orientations. The model was validated by taking a field measurement to measure and quantify the temperature of a selected room taken within three consecutive days in May and June 2019 and compared to the simulation tool results, the average error percentage was 2.15%. The results of the simulation showed that changing glass type can reduce energy consumption by up to 18.8%, indicating the significance of energy efficient retrofitting of existing residential buildings.

ROLE OF GEOGRAPHIC INFORMATION SYSTEMS (GIS) IN LOCATING THE MOST SUITABLE SITES FOR HAZARDOUS MEDICAL WASTE DUMPSTERS (CASE STUDY: SOHAG CITY)
Hazardous medical waste is a very serious source on human health and environmental system،for its highly hazardous chemicals، organic، and radiant content. The disposal process of hazardous medical waste is carried out in several stages: collection، sorting، storage، transportation and treatment، and ending with the final safe disposal. The final disposal phase is an important stage from these stages. The landfill or burial is one of the most important methods of waste final disposal process. This is done by using waste dumpsters with specific specifications prepared for this purpose. It is important in this regard to determine the location of sanitary dumpsters، which need to determine their places accurately، in a way that does not adversely affect the environment، and provide adequate safety means، by using scientific methods as a substitute for the traditional means of self-experience and decision-makers experience. From here the study importance in Sohag city،where Sohag is one of the areas that suffer from medical waste management and disposal problem in accordance with the principles and standards of health and safety the public، Where the reliance on the means of burning only for the final disposal of tit at the complex of incinerators in (Kawther) area، Sohag city، which is not contain any sites for the burial of hazardous medical waste.

ROLE OF THE TECHNIQUE OF RECONSTRUCTION IN THE PRESERVATION OF THE HERITAGE BUILDINGS
The technique of reconstruction for the demolished parts of heritage buildings is considered as one of the most important issues in the field of preservation. The technique of reconstruction concerns either with the collapsed or destroyed parts of the building or with missed ones in times not far away.Generally, the reconstruction process is the reassembling of the heritage building parts and reconfiguration thereof, wholly or partially, for the purpose of restoration of the original shape of the building. The technique of the reconstruction process is mostly associated with the disasters which may occur to the heritage buildings and cause the destruction thereof, wholly or partially, such as the earthquakes, floods, fires and wars. Such process shall be carried out depending on intensive studies and accurate documents of the building shape and details.The research discusses the technique of reconstruction in the preservation of the heritage buildings, through an analytical descriptive presentation to practical models clarifying the research idea and explanation thereof. The research had discussed several points, the most important ones thereof being the values and standards distinguishing the heritage buildings and the different techniques for preservation of such buildings, and then the research touched on the nature and patterns of the operations for reconstruction of the heritage buildings and the rules and determinants governing them, in addition to, the different trends thereof, by taking practical examples illustrating the techniques of the patterns of the operations for reconstruction of the heritage buildingsThis research is concluded by presenting the most important results achieved which are summed up in that the process for reconstruction of the demolished or collapsed heritage and historical buildings represent the only available means to be resorted to, due to, the collapse of parts of the building in a manner that lets no other option exists there, and it is the optimum technique which ensures continuity of the heritage buildings survival in the architectural and technical details thereof. The reconstruction process must be conducted depending on specialized studies and accurate documents showing the building shape and its different details whenever possible.

THE FUTUER OF URBAN GROWTH IN EGYPT ASSESSMENT OF CURRENT TRENDS AND FORGING NEW APPROACHES FOR SUSTAINABLE DEVELOPMENT
Since the seventies of the last century, Egypt has taken serious steps towards adopting the policy of establishing new cities to alleviate the encroachments on agricultural lands and to re-distribute the population on the desert lands adjacent to the valley, and then the homogeneous re-distribution of the population over the entire area of the country to achieve economic, social and security objectives. This policy has gone through four phases or generations of new cities of various types (independent, satellite and twin cities), but for economic, social and implementation reasons, this policy has not been able to achieve its full objectives. As a result the greater Cairo became a huge urban agglomerate with internal trips of more than 100 km length, making its service facilities and networks is too difficult, and worsened its environment, and pollution rates have increased to unprecedented rates, However, the urban area of the country has not increased by more than 3% in five decades and its population and urban densities- in the Nile valley and its surroundings- has doubled, while most of the European countries are establishing small and medium urban communities with a population of between 10000 and 50,000 and between 50000 and 500000, which can be free from mechanical movement, which preserves the environment and reduces pollution rates, as the problems and challenges faced by mega cities than the small and medium communities, Thus, the research concludes that the future of the Egyptian urban sprawl should adopt the policy of distribution of small and medium urban settlements on the axes of regional roads and consider them as axes of development to redistribute the homogeneous population over the entire country rather than the too long agglomeration and the mega cities.

DESIGN PATTERNS FOR MIDDLE-INCOME CONTEMPORARY DWELLINGS IN IBB CITY- YEMEN
As a result of the great changes witnessed in Yemen in general and the city of Ibb especially since the establishment of Yemeni unity in from 1990 to 2018, from the economic, political, social, cultural and intellectual aspects, due to the migration from the rural to the urban area and the resulting increase in the need for housing construction, and in the absence of laws, legislation and awareness community, in Ibb city emerged New design patterns in residential buildings for middle-income people due to those changes.This paper studies the changes in design patterns of residential buildings in Ibb and monitored them to benefit from them in the modern housing sector by the cultural and economic structure of society and meet the new and contemporary functional needs of the population. The paper adopts the descriptive documentary approach to track residential patterns in traditional and modern housing before and after the revolution of 26 September 1962 until the end of the twentieth century, and then conducting a field study of the contemporary residential buildings for middle - income people in Ibb and extracting the changes that occurred in the design patterns of the housing units of this category. The research found that there are four design patterns for residential buildings in the city of Ibb, they are results of the economic level of the population and cultural, functional and social disparities, which contributes to the assimilation of housing-related institutions and architects of the changes in design patterns of buildings Which were produced by economic, cultural, intellectual and political changes, which in turn contribute to the improvement of the residential environment of this category, by responding effectively to the trends of the population and their potential in order to meet their housing needs, The paper concludes with a set of findings and recommendations that contribute to the production of housing that meets the needs of middle-income population category, linked to the past related to the present and future and appropriate to the reality of the population and their potential and trends.
