In the hospital environment, the complexity of the building configuration causes wayfinding difficulties for hospital users. This results in s tress, anxiety, discomfort, loss of time, and missed appointments. This research es tablishes the critical factors that influence the ease of wayfinding in a hospital environment with consideration for the design sys tems. The s tudy was carried out at Jos University Teaching Hospital, Plateau S tate, Nigeria. Also, a descriptive research design was employed with a survey ques tionnaire for data collection, adminis tered on outpatients on a sample size of 96 respondents (48 males and 48 females), using a simple random sampling technique. Findings from factor analysis and multiple regressions showed that some factors have a high influence on the ease of wayfinding in the hospital environment concerning their loadings at significance value. These factors include landmarks, crowdedness in the circulation spaces, circulation intersection (nodes), and visual access. The s tudy recommends that local landmarks should be designed to be visible from a dis tance at decision-making points in the hospital during wayfinding. Furthermore, circulation intersections (nodes or junctions) should be dis tinctive with directional signs and should have visible cues to reduce wayfinding errors at such decision points. This implies that spatial and visual factors should be considered in hospital wayfinding designs.

Various researches have introduced methods to use daylight in office buildings in the Middle Eas t zone, but none of them have ever considered the use of plant leaf arrangement, called phyllotaxis, as a comprehensive solution for harves ting daylight. The idea of the Phyllotaxis Tower has been raised for several years but the main ques tion of this research is whether using the phyllotaxis model is capable of exploiting daylight in high-rise buildings or not. So, in response to this ques tion, the main aim of the research was set to evaluate daylight efficiency in high-rise office buildings by presenting an exemplary and phyllotaxis-inspired design. The research method is encompassed several s teps including, s tudying the literature on the subject firs tly, then modeling a prototype building based on the Biomimicry Problem-Based approach, and eventually computer simulation to evaluate the performance of the proposed building. The results show that office units can get daylight illuminance of 500 lux at 50% of operating time per year in addition to proper performance on four single days of different seasons of the year. Furthermore, the sample building obtained label B of energy consumption from S tandard No. 14254 presented by the Ins titute of S tandards and Indus trial Research of Iran, which has been compared with the energy label of 45 office buildings in the same location and same climate conditions, based on the figures are defined on the aforementioned s tandard and has the bes t performance among them.

 One of the mos t important principles in the formation of Iranian-Islamic cities is the principle of unity. Observing the principle of unity in the physical-social space of his torical neighborhoods has led to the organization and integration of them. A review of s tudies on this issue indicates that the principle of unity in the scale of urban neighborhoods has been less considered. The main ques tion of the s tudy is how and with what factors and criteria was the principle of unity formed in the physical space of Sarshoor neighborhood, Mashhad city? This s tudy is his torical and analytical research. The research process is divided into two main s tages. In the firs t s tage, it is attempted to determine how the spatial s tructure of the Sarshoor neighborhood was before the extensive physical-spatial interventions taken in the contemporary era. In the second s tage, the factors and criteria related to the principle of unity are determined on the maps and photos of the neighborhood in an exploratory way and using the relevant graphical analysis. The results show that in the his torical neighborhood of Sarshoor, a set of factors in a complex and close relationship with each other, have been effective in unifying the physical space of the neighborhood. Factors including "connectivity and continuity", "centrality", "hierarchy", "coordination", "interconnectedness" and "semantic unity" have been effective in realizing the principle of unity in the neighborhood by creating various qualities in different dimensions of physical space of the neighborhood.

More than eight hundred years ago, before the invention of digital tools, Muslim builders had achieved the creative vision and aes thetic complexity required for the production of Muqarnas: an architectural device that connects surface ornament to divine concepts. This research adopts a qualitative, comparative, and critical use of architectural source material to cons truct an alternative unders tanding of Muqarnas within a documented his tory of architectural allegories and theories. The paper follows the argument that in the absence of figurative depiction in Islamic art, geometry assumes greater symbolic power, which manifes ts itself in ornament, s tructure, and space. In this sys tem, Muqarnas uses complex geometry to connect wall surfaces to spacious volumes. In the metamorphosis of two-dimensional planes to three-dimensional space, Muqarnas occupies the in-between space that connects the two worlds in a smooth and parametric process of transition. Thus, Muqarnas operates similarly to the folds of Baroque architecture and expresses, in a manneris t, yet geometric manner, the connection between the two realms of body and soul. However, unlike the Deleuzian model of Baroque sacris ty, light does not enter from below; from the realm of the body and the senses, but rather it shines from above; from the realm of the soul and divine concepts. From this point of view, Muqarnas becomes a significant phenomenon in architecture being a symbolic, ornamental, and parametric architectural device that simultaneously alludes to the allegories of the Platonic tradition, the Deleuzian concept of fold/unfold, and to recent theories of Parametricism.

The urban landscape is an objective-subjective nature that plays a significant role in the perception of collective spaces by the audience. This is possible only by s timulating the perceptual potentials of users and inducing behavioral patterns to users of a space. This s tudy inves tigates the role of urban landscaping in the perception of collective spaces using perceptual potentials. This research is descriptive-analytical and, in terms of purpose, is applied. A ques tionnaire did data collection, and for data analysis, Spearman and Friedman's s tatis tical tes ts were used in SPSS software. A case s tudy is the third square of Tehranpars, where the target community has also been selected as users of this space. In the data collected from the sample group, the highes t level of correlation between the sub-components of objective aes thetics is the composition and color indices with a correlation coefficient of .857. Among the sub-components of subjective aes thetics, the penumbra indices and physical cohesion with a correlation coefficient of 0.690 have the highes t level. In addition to the relationship between the proposed indices, the priority of these indices is ranked based on the Friedman tes t, and it is observed that the indices of composition (7.98), readability (5.89), and physical coherence (5.76) have the highes t priority among the ranking of indices in terms of the s tatis tical population. These data-driven priorities can identify design priorities and help take adequate s teps to create a vitality urban space.
