This study explores the acceptance of different wood coverages on building facades with the aim of optimization of materials, and in turn improving overall sustainability. It firstly develops the principal physical variables and evaluation criteria; then, test models are created using an orthogonal design experiment; finally, two evaluation methods are used to comprehensively test acceptance, based on a questionnaire and an eye-tracking study. The results show that: (1) The effects of the amount of wood coverage and the wood patterns are significant, whereas the effect of material combinations is insignificant. (2) The acceptance of building facades is at the highest level when the amount of wood coverage is 65%. (3) The amounts of wood coverage for facades in the range of 35% to 50% are effective when designing the facade of wood buildings, in order to implement the dual targets of saving wood and higher acceptance.

Structural Behaviors

A fabricated mobile scaffold has various components, including vertical members, horizontal members, braces, work plates, and castor wheels. In Korea, the structural performance of each member must be validated based on member-level structural safety criteria; this means that rigorous evaluation methods are required to secure the system-level structural safety of the fabricated mobile scaffold. To suggest rational system-level structural safety criteria and effective evaluation methods, the characteristics of the structural behaviors of the assembled structure must be investigated first. Unlike other temporary equipment, it is a product that requires convenience of use and ease of movement. Therefore, to secure the safety and usability of the structure, it is necessary to evaluate the ultimate behavior of a mobile scaffold fabricated with various material and structural types. In an experimental study, the ultimate mode and load-bearing capacity were investigated, and the appropriateness of the required performance of the mobile scaffold was reviewed. Three types of experimental test models with different materials (steel and aluminum) and stories (single-story and three-story erection) were selected and examined for vertical loads. Based on the experimental results, the ultimate behavior characteristics of the fabricated mobile scaffold were analyzed, and the ultimate load was identified.

This chapter examines the literature on evaluation methods within e-learning with respect to their applicability to evaluate e-portfolio systems within higher education as evaluation criteria for reviewing e-portfolio provisions do not currently exist in the literature. The appr­oach taken is to initiate two extensive literature searches and reviews. The first search was undertaken in 2009 involved reviewing over 600 articles by abstract dating from 1995 to 2010 to develop evaluation criteria suitable for Blackboard LMS e-portfolio systems evaluation. The second search undertaken in 2013 involved extending the search criteria to include further terminology and databases and returned over 4107 articles, which were read by title and abstract dating from 2009 to 2013, in order to systematically map evaluation methods used within e-learning to assess their quality and applicability for evaluating e-portfolio systems. The implications of the research undertaken provide a starting-point for further research into the development of robust e-portfolio evaluation models and frameworks. The lack of evidence uncovered in the 2009 and 2013 searches of the literature justify the need for further research into the design, development, and testing of evaluation methods for the evaluation of e-portfolio systems.

This chapter describes the evaluation methods conducted for a digital heritage system, called ARCO (Augmented Representation of Cultural Objects), which examines the tools and methods used for its evaluation. The case study describes the knowledge acquired from several user requirement assessments, and further describes how to use this specific knowledge to provide a general framework for a holistic virtual museum evaluation. This approach will facilitate designers to determine the flaws of virtual museum environments, fill the gap between the technologies they use and those the users prefer and improve them in order to provide interactive and engaging virtual museums. The proposed model used not only quantitative, but also qualitative evaluation methods, and it is based on the extensive evaluations of the ARCO system by simple end-users, usability experts and domain experts. The main evaluation criteria were usability, presence, and learning.

Image Segmentation Evaluation

Image segmentation consists of subdividing an image into its constituent parts and extracting those parts of interest (objects). Due to its importance in image analysis, many research works have been conducted for this process. After 40 years of development, a large number of image (and video) segmentation techniques have been proposed and utilized in various applications (Zhang, 2006). With many algorithms developed, some efforts have been spent also on their evaluation, and these efforts have resulted around 100 evaluation papers that can be found in literature for the last century. Several studies have been made in the past in attempt to characterize these existing evaluation methods (Zhang, 1993; Zhang, 1996; Zhang 2001). Segmentation evaluation methods can be classified into analytical methods and empirical methods (Zhang, 1996). The analysis methods treat the algorithms for segmentation directly by examining the principle of algorithms while the empirical methods judge the segmented image (according to predefined criteria or comparing to reference image) so as to indirectly assess the performance of algorithms. Empirical evaluation is practically more effective and usable than analysis evaluation (Zhang, 1996). Recent advancements for segmentation evaluation are mainly made by the development of empirical evaluation techniques. After providing a list of evaluation criteria and methods proposed in the last century as background, this article will provide a summary of the recent (in 21st century) research works for empirical evaluation of image segmentation. These new research works are classified into three groups: (1) those based on existing techniques, (2) those made with modifications of existing techniques, and (3) those that used dissimilar ideas than that of existing techniques. A comparison of these evaluation methods is made before going to the future trends and conclusion.

Association rule is an important model in data mining. It describes the relationship between predicates in transactions, makes the expression of knowledge hidden in data more specific and clear. While the developing and applying of remote sensing technology and automatic data collection tools in recent decades, tremendous amounts of spatial and non-spatial data have been collected and stored in large spatial database, so association rules mining from spatial database becomes a significant research area with extensive applications. How to find effective, reliable and interesting association rules from vast information for helping people analyze and make decision has become a significant issue. Evaluation methods measure spatial association rules with evaluation criteria. On the basis of analyzing the existing evaluation criteria, this paper improved the novelty evaluation method, built a spatial knowledge base, and proposed a new evaluation process based on the support-confidence evaluation system. Finally, the feasibility of the new evaluation process was validated by an experiment with real-world geographical spatial data.

Morphological Criteria

A rapidly growing development of tissue engineering promotes the increasing interest in the obtainment of various decellularizedtissues and organs. Minimal quality evaluation criteria of obtained tissue engineered constructions have been previously specified. In the discussionpaper the group of authors considers the morphological methods of matrix evaluation applied by various researchers on the model of heart decellularization. The analysis of modern literature and the authors’ own researches have shown that morphological evaluation of decellularization quality has to be complex and should consist of several stages which include both basic and additional evaluation methods.
