1. Introduction The university campus is the total physical environment, including all buildings, open spaces and landscape elements (Aydin and Ter, 2008). It is this combination of buildings and landscaped open spaces between buildings that functions as an organized whole with a distinctive identity (Gehl, 1987). Rapoport (2004) states that these environments are structured and composed of fixed (infrastructure and buildings), half-fixed (open spaces and their components) and non-fixed (users, user actions and vehicles) elements. Half-fixed open spaces and components are the important determinants of the environment’s influence on user attitudes (Aydin and Ter, 2008; Lefebvre, 1991; Abu-Ghazzeh, 1999; Dober, 2000). The design qualities of these open spaces are related to their spatial, social, cognitive and affective characteristics (Adedeji, Bello and Fadamiro, 2011; Adedeji and Fadamiro, 2012). The spatial characteristics are the design considerations and include accessibility in terms

of circulation systems, opportunities for spatial preferences, way-finding and location qualities (Helsper, Johnson, Johnson, Rubba and Steiner, 1990; Arenibafo, 2016; Heitor, Nascimento, Tomé and Medeiros, 2013; Payne, 2007; Muñoz, 2009; Ambler, Webb, Hummell, Robertson, and Bailey,
2. Statement of the Research Problem Designers of UCOS including UZGs are not fully acquainted with the performance of the spaces during their use. This leads to repetition of design mistakes and the university community using the spaces in ways that were only partially predicted (Watson and Thomson, 2005; Venkat, 2011; Cubukcu &Isitan, 2011). As a result, the satisfaction of the users that can enable the formulation of EBD framework as a feed-back process is grossly missing. 2.1 Research Questions, Objectives and Hypotheses Enhancing the performance of UZGs is contingent on users’ satisfaction. This study’s concern about users’ satisfaction is guided by the following questions: i What is the perception of quality and factors that underpin the users’ satisfaction with the UZGs? ii. What aspects of user satisfaction can inform design frameworks for UZGs? Accordingly, the study seeks to: i. Examine the perception of quality and factors influencing users’ satisfaction with the UZGs; and ii. Develop design policy framework for UZGs. To guide the study, the following hypotheses were formulated: HO 1 There is no significant difference in the perceptions of qualities of the UZGs among the Federal Universities in the study area. HO2 Perception of quality is not contingent upon satisfaction of the users with the UZGs in the study area.
data was used to identify the statuses of the users, evaluate their perception of quality of the open spaces, analyse the relationship between their statuses and perception of qualities, examine the factors influencing their satisfaction and develop policy framework for Zoological gardens in Federal Universities in South-west Nigeria.
4. Data Presentation and Analysis 4.1 Status of the users and perception of quality of the UZGs Table 1 reveals the status of the users of the UZGs. The users are disproportionately males (62.3%) than females (37.7%), mostly undergraduates (87.5%) in the active age bracket of 19-45years (91.5%). That all categories of users are adequately represented suggests the result should be adequate for generalization synthesis. Their perception of quality of the UZGs as shown in Table 2 are also reliable since they are well acquainted with the gardens and therefore their value-judgments can be upheld. Table 1.

4.2 Testing of Hypothesis HO 1 : There is no significant difference in the perceptions of qualities of the UZGs among the Federal Universities in the study area. A Kruskal-Wallis H test was conducted to determine if the perceptions of qualities of the Zoological gardens is significantly different among the six Federal Universities and the results are as shown in Table 3. A Kruskal-Wallis H test showed that there was a statistically significant difference in the perceptions of qualities of the UZGs among the six Federal Universities. The results as shown in Figure 2 and explained with chart in Figure 3 indicate that Chi square, χ^2 (df,

Only discipline (Cramer’s V=0.110, p=0.000<0.005) has significant impact at 95% confidence level. Table 4.

The use factors are extrinsic to the UZGs since they have to do with the users themselves on how they use the gardens. The four use factors are common period of use, common purpose of use, mode of pedestrian use and hindrances to use. Table 6 shows that common period of use and mode of pedestrian use do not have significance on the perception of quality of the UZG (Cramer’s V=0.087, p=0.005). Figure 4 shows that those who use the Zoological gardens for academic purposes had higher perceptions of their qualities than other users. Status of users Cramer’s V Value Approx. Sig.

Figure 4. Influence of common purpose of use on the perception of quality of zoological gardens in federal universities in the South-west Nigeria. Figure 5 shows that the perception of quality of Zoological gardens is influenced by the purpose of use. Those that use them for group academic, being alone and personal academic purpose perceive the gardens to be of higher quality than utilitarian and passive recreation. Figure 5. Influence of common purpose of use on the perception of quality of Zoological gardens in Federal Universities in South-west Nigeria. Furthermore, hindrances to use significantly influenced the perceptions of qualities of the UZGs at 0.01 (99%) confidence level as shown in Table 6. Figure 6 shows that inclement weather and lack of visual privacy accounts for perception of qualities. Figure 6.

The other intrinsic factors are social, spatial and affective factors. A Spearman’s rank-order correlation was run to determine the relationship between 1759 users’ satisfaction with four cognitive factors (coherence, legibility, complexity and mystery) and perceptions of qualities of the UZGs, both measured in ordinal scales. There were strong, positive correlations between satisfaction with the cognitive factors and perceptions of qualities of the UZGs which was statistically significant as follow: coherence: rs = .355, p = .000; complexity: rs = .349, p = .000; mystery: rs = .315, p = .000; and legibility: rs = .314, p = .000, in descending order, as shown in Table 7 and Figure 7.

Comfortableness 0.283 0. 3.5 Testing of Hypothesis Ho2: Influence of Satisfaction Factors on Perceptions of Quality Ordinal regression analysis was carried out to estimate the 30 intrinsic satisfaction factors (cognitive, social, spatial and affective factors) influencing the perception of quality of the UZGs. Accordingly, model fitting information and Pseudo R-Square were generated as shown in Table 8. The dependent variable which measures the perception of quality is the UZGs. UZGs is equal 1 if the respondent perceives the garden as poor, 2 as scanty, 3 as averagely set, 4 as well set and 5 as excellent. Since dependent/outcome variable is ordinal, and the satisfaction factors, SF (independent/predictors) are measured as ordinal variables (SF is equal 1 if the respondent is very unsatisfied with the performance of the open space based on the SF under consideration, 2 for unsatisfactory, 3 for fairly satisfactory, 4 for satisfactory and 5 for very satisfactory) the ordinal regression model is used to estimate the factors which influence satisfaction of the users. Only the 30 satisfaction factors that are intrinsic to the UZGs were included in the model. Use factors were excluded since they are extrinsic to the UZGs. The results in the Model indicate that as the ratings of the satisfaction factors increase, the perception of quality increases and the model is significant at the .01 level (99% confidence level). This is for Cox and Snell (theoretical maximum value of less than 1), Nagelkerke (adjusted version of the Cox and Snell R^2 to cover the full range from 0 to 1) and McFadden’s (based on the log-likelihood kernels for the intercept-only model and the full estimated model) Pseudo R^2 , since it is not possible to compute a single R^2 statistic that has all of the characteristics in the linear regression model for regression models based on ordinal data (Tjur, 2009). According to Cox and Snell Pseudo R^2 , Table 8 shows that the model predicts that the satisfaction factors, SF [Chi-square=3866.018, df=245, p=0.000, 2 Log Likelihood final=102.613] accounts for 95.0% of the variance in the perception of quality of UZGs. Table 9 shows the Parameter estimates (beta coefficients) of the intrinsic factors influencing users’ satisfaction. The estimates are based on scale models which depend on the main and interaction effects. Three intrinsic satisfaction factors are the best predictors of perception of quality as highlighted. Table 9 suggests that satisfaction with legibility (0.574) is the best predictor of perception of quality of Zoological gardens. This is followed consecutively by beautifulness (0.331) and walk-ability (0.325). Furthermore, satisfaction with social interaction space (0.434) is a better predictor of perception of quality, being the highest, than restfulness (0.423) and walk-ability (0.356) consecutively.

adjustments of existing UZGs for better users’ satisfaction. Contextually, the study was limited in scope to Federal Universities. Further work can be carried out inclusively and exclusively with other proprietorships of universities within and outside the South-west Nigeria. Such can be for comparative purposes or case studies and can include considerations like maintenance and management of UZGs. In term of methodological approach, since this work is limited to quantitative research design on cross- sectional basis, qualitative and/or mixed method paradigms that can also be longitudinal can be further engaged on different spatial scales. On the whole, the perception of quality is related to the satisfaction factors such that as the ratings of the satisfaction factors increase, the perception of quality increases. The satisfaction factors therefore account for the significant differences in the perceptions of qualities of the UZGs among the six Federal Universities in the study area. The satisfaction factors that account for the perceptions of qualities of UI Zoological should be programmed into the design of UCOS to avoid the misuse of spaces and best decisions to be taken during the design process.
