- چکیده:
- چکیده انگلیسی: Although many attempts have been made in presenting systematic models for design processes, most projects have been implemented by non-systematic methods, which seems that too much emphasis on the description of the final project (product) and the lack of attention to the design process are to be blamed for this. In this paper, a specific pattern of design scenario formation in the framework of a research-oriented design process will be discussed. Therefore, the aim of this study is to develop a model that can be used in research-based design processes. In the present study, conceptual structures are extracted in the theoretical frameworks for each stage of the design scenario formation process by reviewing the literature of the subject, and then these conceptual structures are placed next to each other and presented in the form of a systematic process called research-oriented design process. The process presented in this paper is the result of the experience gained during 5 years of teaching an architectural design (2), which includes three milestones: 1) Design protocol 2) Subconcepts and 3) Design scenario. This scenario is precisely coordinated and aligned with the design protocol; it also reveals behaviors that require a design response, explains clearly the scenario of the details of the activities and the elements that make up the spaces. This makes the subject more transparent in the minds of designers and details of the design for each stage should be determined.

- چکیده:
- چکیده انگلیسی: Statement of the Problem: Adequate compressive strength is an important characteristic for an ideal liner.
Purpose: This study aimed to assess the compressive strength of several commonly used liners.
Materials and Method: This in vitro, experimental study evaluated 120 samples fabricated of Dycal, Calcimol LC, Vitrebond, Activa Bioactive, and TheraCal LC (n=24) liners according to the manufacturers’ instructions. The samples were fabricated using a cylindrical stainless steel mold with 6±0.1 mm height and 4±0.1 mm internal diameter. Half of the samples in each group (n=12) underwent compressive strength test immediately after completion of their primary setting while the other half (n=12) underwent compressive strength test after 24 h. During this period, the samples were immersed in deionized water (grade 3) and incubated at 37±1°C and 100% humidity for 24 h. The compressive strength was measured using a universal testing machine. Data were analyzed using two-way ANOVA followed by Tukey’s post-hoc test.
Results: The compressive strength of the five liners was significantly different (p < 0.05). Calcimol LC showed maximum compressive strength both immediately after setting and after 24 h. The compressive strength at 24 h was significantly higher than the primary compressive strength in all groups (p < 0.05).
Conclusion: Within the limitations of this study, it seems that Calcimol LC, Activa Bioactive Liner, and TheraCal LC have adequate compressive strength and can be used alone to provide adequate support for the restorative materials.- انتشار مقاله: 13-11-1398
