A Study on Oral Health Care System Designing for the Middle-Aged Based on SAPAD-PCA

Objective: In this paper, we paid attention to the oral health care for the middle-aged, reorganized and consolidated the resource of all related parties, and improved the experience of the oral treatment to the middle-aged. As a result, we could improve the level of their oral health. Methods: We analyzed the mapping of activities, objects and meanings with the theory framework of Semiotics Approach of Product Architecture Design (SAPAD). Then we obtained the meaning clusters through the method of cluster analysis. We introduced the method of Principal Component Analysis (PCA) to analyze the meaning clusters quantitatively and calculate information contribution rates so that we could get the core meaning clusters. Result: We finished the mapping of meanings and objects by analyzing the relationships between them which were behind those core meaning clusters. Then we achieved the user’s key behaviors and found their real needs. With this step, we succeed in the improvement of experience about the oral health care service system for the middle-aged. Conclusion: We studied the treatment process of oral treatment for the middle-aged by combining the SAPAD framework and PCA method, which we researched about users’ behaviors deeply and found their key needs by the quantitative method. So we could think about problems and solve them more objectively and comprehensively. From the aspect of methods, we had perfected the SAPAD framework and had some creation. Finally, we made use of the SAPAD-PCA model to the oral health care service system for the middle-aged and provided a new solution to the improvement of their oral health.
