Chinease-Korean Cultural Map, which is an electronic cultural map that shows Chinese-Korean culture on maps, is planned as the first step to development Asian Electronic Cultural Map. Chinese-Korean have their unique cultural characteristics same as other small tribes. Small tribes shows same typical cultural characteristics of Asian, and that characteristics are very important factors for understanding the whole Asian culture. This paper proposes a logical and standardized development methodology for construction of Electronic Cultural Map. The methodology consists of 6 steps; information analysis, keyword extraction, keyword clustering, map element extraction, prototype design, and map development. We used and evaluated the methodology during prototype design and development steps for the optimal functions. To generate the base maps for Chinese-Korean Cultural Map, we use Google Earth and KML(Keyhole Markup Language) for standardized and easy development.

Purpose: Practical training in pediatric nursing gives students the opportunity to apply nursing knowledge to children in a realistic clinical context. Clinical practice faculty (CPF) and clinical nursing instructor (CNI) have played important roles in the pediatric nursing practicum. This study was conducted to develop a protocol to guide clinical practicum in pediatric nursing. Methods: A service design methodology was employed between August 2020 and May 2021 at four universities and four hospitals in South Korea. The participants were five CPFs, five CNIs, five nursing college graduates, and 60 nursing students. The service design process had four phases: discovery, definition, development, and delivery. Data were collected through self-report questionnaires, in-depth interviews, and observations. The data were analyzed using content analysis and descriptive statistics. Results: The participants reported needs for providing concrete guidance and explanation, nursing practice experience, and a link between school and the clinical field. A protocol was developed to fulfill the participants' needs. The protocol comprised detailed information, teaching methodology, and partnership to guide students in the pediatric nursing practicum. Conclusion: The protocol developed in this study can be used to provide guidance for students' clinical practice in the field of pediatric nursing.

This study focused on the development of simulation methodology and design optimization for the DBR(Distributed Bragg Reflectors) structures, which are commonly used in manufacturing optical films and the key components of LED chip and LCD inspection equipments. From the multi-layer simulation, the following results are obtained. First, the wavelength(nm) vs. reflectance(%) can be calculated in the DBR structures that $TiO_2$ and $SiO_2$ thin films are stacked alternately. As a results, it is suggested that highly efficient DBR structures can be designed and manufactured using simulation methodology.

This paper presents a review on getting a Weighted Multi-Objective Optimization (WMO) of Tuned Mass Damper (TMD) parameters based on Response Surface Methodology (RSM) coupled central composite design and Weighted Desirability Function (WDF) to attenuate the earthquake vibration of a jacket supported Offshore Wind Turbine (OWT). To optimize the parameters (stiffness and damping coefficient) of damper, the frequency ratio and damping ratio were considered as a design variable and the top displacement and frequency response were considered as objective functions. The optimization has been carried out under only El Centro earthquake results and after obtained the optimal parameters, more two earthquakes (California and Northridge) has been performed to investigate the performance of optimal damper. The obtained results also compared with the different conventional TMD's designed by Den Hartog's, Sadek et al.'s and Warburton's method. From the results, it was found that the optimal TMD based on RSM shows better response than the conventional damper. It is concluded that the proposed response model offers an efficient approach regarding the TMD optimization.

This paper is about our experience of developing a context-aware exhibit guide system called MyGuide by applying Simtext development methodology. In particular, we introduce some issues to be considered in development process, the way that we solved them, and other things related to context. In requirements elicitation phase, we reduced the complexity of requirements by separating business logic requirements and context-awareness related requirements. After that, we modeled context, and designed software architecture, classes, and database in sequence during design phase. We considered system requirements and context modeling issues for context modeling because it influences class and database design.

Recently, design for additive manufacturing (DfAM) technology has become a prominent design methodology for exploiting 3D printing, which leads the Fourth Industrial Revolution. When manufactured by the 3D printing method, it is possible to produce several shapes compared to the conventional casting or cutting process. DfAM-as a newly-proposed design methodology-can be used to specially design products with various shapes to apply functional requirements. Topology optimization verifies load paths to determine the draft design, and a shape-optimized design with objective functions for weight reduction enables efficient lightweight product design. In this study, by using these two DfAM technologies, a lightweight and optimal design is constructed for a node part of a vehicle body with a space frame designed for a lightweight vehicle. DfAM methodologies for concept design and detailed design, and the associated results, are presented. Finally, the product was additively manufactured, a fatigue performance test was performed, and the design reliability was verified.

A systematic methodology for efficient implementation of processor arrays from regular iterative algorithms is proposed. One of the modern parallel processing array architectures is the Systolic arrays and we use it for processor arrays on this paper. On designing the systolic arrays, there are plenty of mapping functions which satisfy necessary conditions for its implementation to the time-space domain. In this paper, we sue a few conditions to reduce the total number of computable mapping functions efficiently. As a results of applying this methodology, efficient designs of systolic arrays could be done with considerable saving on design time and efforts.
