In the recent years, with a purpose to provide visual and psychological stability to patients and hospital users, Affordance design theory based on perceptual psychological thought has been applied as hospital design. In the past, hospital service design was focused on but Affordance design theory focuses on the patients' experience and methodological research on . The characteristics of the application of Affordance design in the case of patients' experience and service point is as follows:- Firstly, Affordance design is applied when the objective of the patient's experience and the functionality of the object are combined. In other words, affordance design is a condition that arises when encounter between service contact point and patients' experience takes place. Secondly, In the field of Hospital service design, Affordance concepts in and its application can be divided on the functions of experience, cognition and sense following the application of Affordance concepts in Hospital service design. Thirdly, Affordance design method sets meaning of the action received through information provided by morphological features. The condition and surrounding has to be designed in a way that it can induce active behavior of the patient. This study has significance as it has been studied from the perspectives of Affordance theory of design psychology in addition to the physical environment of the hospital, the point of interaction between the hospital and patient, along with the elements of experience design. This study proposes the necessity of analytical study in the field of service design implementation considering various stakeholders in the service contact points of small and medium hospitals in Korea. Furthermore, study of the application of Affordance design can be complemented by reflecting the size of hospitals, the characteristics of specialties, and the specific service environment of each hospital can also be conducted.

This paper presents the procedure for the optimal design of a PSC-I girder bridge considering life cycle cost (LCC). The load carrying capacity curves for the concrete deck, PSC-I girder and $\pi$-type pier were derived and used for the estimate of service lives. Total life cycle cost for the service life was calculated as sum of initial cost, damage cost, maintenance cost, repair and rehabilitation cost, user cost, and disposal cost. The advanced First Order Second Moment method was used to estimate the damage cost. The optimization method was applied to the design of PSC-I girder bridge. The objective function was set to the annual cost, which is defined by dividing the total life cycle cost by the service life, and constraints were formulated on the basis of Korean Standards. The optimal design was performed for various service lives and the effects of design factors were investigated.

This study applies the Delphi method to design services with convergence characteristics in the financial sector. In designing a service robot for practical deployment that can support and replace bank teller, the opinions and judgments of various expert groups were extracted and a consensus process was made through feedback. A total of six dimensions and thirty service elements were derived over three rounds. Coefficient of Variation and content validity were used to verify the suitability and reliability of the selected service elements. As a result, the essential service element of robots was interaction with customers, followed by basic and professional financial services. Based on these service factors, we proposed two types of service models. support mode to assist employees during business hours and alternative mode on behalf of employees outside business hours. It is hoped that this study will use the Delphi technique in the design of IT convergence services.

A Product-Service Systems (PSS) is composed of service and product element to provide values for relevant stakeholders. A typical service interaction involves providers and receivers, and respective values are provided in a social interaction. In cases, more than one providers are interacting with a receiver. In others, service interaction is happening in a public manner where social issues amang peer receivers are important. When service channel is supported by physical touchpoints, receivers would interact with products, which may interact with providers. Thus, in PSS, a various kinds of interactions occur in diverse social contexts. A simple representation method for social contexts is introduced where service providers, receivers and products are represented as nodes and interaction between them are represented as directed edges. Social context of several PSS examples are described with this. In booth designing and operating PSS, social context representations could be used in analyzing and comparing key aspects of social interaction types to retrieve similar cases to exploit related interaction design strategies and operation know-hows.

A fiber spool with ultra-low vibration sensitivity has been demonstrated for the ultra-narrow-linewidth fiber-stabilized laser by the multi-object orthogonal experimental design method, which can achieve the optimization object and analysis of influence levels without extensive computation. According to a test of 4 levels and 4 factors, an L₁₆ (4⁴) orthogonal table is established to design orthogonal experiments. The vibration sensitivities along the axial and radial directions and the normalized sums of the vibration sensitivities are determined as single objects and comprehensive objects, respectively. We adopt the range analysis of object values to obtain the influence levels of the four design parameters on the single objects and the comprehensive object. The optimal parameter combinations are determined by both methods of comprehensive balance and evaluation. Based on the corresponding fractional frequency stability of ultra-narrow-linewidth fiber-stabilized lasers, we obtain the final optimal parameter combination A3B1C2D1, which can achieve the fiber spool with vibration sensitivities of 10^-12/g magnitude. This work is the first time to use an orthogonal experimental design method to optimize the vibration sensitivities of fiber spools, providing an approach to design the fiber spool with ultra-low vibration sensitivity.

Compared to the significant approach of project-based learning research, a data-driven design project-based learning has not reached a meaningful consensus regarding the most valid and reliable method for assessing design creativity. This article proposes an advanced information data-interactive learning system for creative design using a service design process that combines a design thinking. We propose a service framework to improve the convergence design process between students and advanced information data analysis, allowing students to participate actively in the data visualization and research using patent data. Solving a design problem by discovery and interpretation process, the Advanced information-interactive learning framework allows the students to verify the creative idea values or to ideate new factors and the associated various feasible solutions. The student can perform the patent data according to a business intelligence platform. Most of the new ideas for solving design projects are evaluated through complete patent data analysis and visualization in the beginning of the service design process. In this article, we propose to adapt advanced information data to educate the service design process, allowing the students to evaluate their own idea and define the problems iteratively until satisfaction. Quantitative evaluation results have shown that the advanced information data-driven learning system approach can improve the design project - based learning results in terms of design creativity. Our findings can contribute to data-driven project-based learning for advanced information data that play a crucial role in convergence design in related standards and other smart educational fields that are linked.
