  • Modern corporations are changing their strategies from 4P-based marketing strategies which have been used for logic-based consumers in the past to perception-based marketing strategies which will be performed for current emotion-based consumers. Therefore, the importance of emotional marketing, which means the integrated strategies approaching consumers by combining logic-based marketing strategies and emotion-based design strategies, has been increased. However, existing researches have not tried to suggest the essence and research scope of design marketing and verify the applicability of each research sectors but only tried to apply some marketing tools in design process. Regarding this, this study suggests that the essence of design marketing has to be defined first then various and systematic academic reviews have been performed on each research sectors of it before design marketing tools are applied in design practices. In addition, this study suggests 3 research categories of design marketing based on traditional marketing. They are first, understanding consumer's decision making precess for design and next, introducing and applying various research tools ant last, applying various strategic tools for strategy-making based on situation understanding. Finally, this study suggests future research directions on 3 research categories mentioned above.

  • Risk-informed approach has been widely applied in the safety design, regulation, and operation of nuclear reactors. It has been commonly accepted that risk-informed design optimization should be used in the innovative reactor designs to make nuclear system highly safe and reliable. In spite of the risk-informed approach has been used in some advanced nuclear reactors designs, such as Westinghouse IRIS, Gen-IV sodium fast reactors and lead-based fast reactors, the process of risk-informed design of nuclear reactors is hardly to carry out when passive system reliability should be integrated in the framework. A practical method for new passive safety reactors based on probabilistic safety assessment (PSA) and passive system reliability analyze linking is proposed in this paper. New three-dimension frequency-consequence curve based on risk concept with three variables is used in this method. The proposed method has been applied to the determination optimization of design options selection in a 10 MWth lead-based research reactor(LR) to obtain one optimized system design in conceptual design stage, using the integrated reliability and probabilistic safety assessment program RiskA, and the computation resources and time consumption in this process was demonstrated reasonable and acceptable.

  • This research discusses user's context based design methodology for location-based AR contents design. A media contents regarding mobile service should be designed considering user's context in dynamic environment. In this regard, I would like to suggest user's context centered design method for augmented reality contents. There are two different research methods in conventional context-based design method. This research tries to totalize two methods. In this sense, this research investigated previous researches which make a new design method. And then, context-based design methods are compared and the pros of them are integrated so as to create a new context-based design method. This new methodology aims to be an effective design method of creating AR contents in the future.

  • This study analyzed the "research trends and the design processes" of the traditional patterns by examining the previous researches on the application of the traditional patterns. For this purpose, 96 studies which include master's and doctoral theses and research papers published in 8 Korean academic journals on Clothing from 2000 to 2010 were chosen. The findings of this study are as follows: First, when the previous researches on the application of the traditional patterns were classified according to their subject matter, they were classified into: research on clothing design, research on textile design, research on the design of cultural commodities, and research on mixed design. Second, the researches that were classified according to their subject matter were re-classified according to their year of publication. It was shown that the most active research was on the clothing design. The research on textile design, when compared with clothing design, alternated an increase and an decrease in every other year. Also, research on the design of cultural commodities were fewer than the research on clothing design or textile design although it is on the increase from 2008. Third, when classified according to the types of design, it was found that the designs based on a flora were most common. Fourth, in most cases, in the process of the designs, the designswere dispensed with the original form or were simplified. The choice of the tone of color, in most cases, were based on the concept selected by the designer. The most common method for the expression of the designs was based on the printing. Also, when it came to the presentation of the designs, the original work greatly outnumbered an imaginary work. Based on this study, it is hoped that there will be more active research on the application of the traditional designs which, in turn, can popularize the aesthetic beauty of Korea.

  • Purpose: Evidence-based design is the process of making design decisions based on reliable research to achieve the best results, so it is important to accumulate reliable evidence through research. Therefore, the purpose of this study is to present new evidence by applying the evidence-based design process to improve the digital signage for each room spaces in hospitals and verifying its effectiveness. Method: Through the 8-step process of evidence-based design, improved digital signage for each room spaces are installed. It conducted surveys and statistical analysis to prove hypotheses by linking design and research. Results: The hypotheses established in the study are: 1) improvement in the readability of digital signage is correlated with patient satisfaction; 2) Improving the intuitiveness of digital signage correlates with patient satisfaction; 3) Improving the sufficiency of digital signage correlates with patient satisfaction. As a result of satisfaction analysis and correlation analysis, all of the above hypotheses were proven. Implications: Although the hospital sign system is the element that patients rely on most intuitively in the long journey of reception, waiting, examination, and treatment, there is insufficient evidence to refer to or apply it when designing. It is necessary to expand future research to expand the evidence that can be applied to hospital sign design.

  • Tall building has some controversial aspects with low carbon city, but it is still a sensible choice for the metropolitan city. This paper aims to develop holistic urban design strategies to minimize impacts on the environment, increase energy efficiency and improve the quality of living in tall building communities by utilizing tall building characteristics. It puts forward the concept of integrated tall building-low carbon community design from the perspective of urban design, and summarizes five core strategies: Temporal state based on energy use, Complementary energy use state based on functions, Spatial state based on regional environment features, Transportation state based on low-carbon lifestyle and Waste utilization state based on tall building characteristics. It also applies the strategies to a practical project. The results show that the proposed urban design strategies are available approaches to mitigate the side effects of tall building on low carbon city.

  • A performance-based design (PBD) procedure, initially proposed for the seismic design of buildings, is tailored herein to the structural configurations commonly adopted in bridges. It aims at the efficient design of bridges for multiple performance levels (PLs), achieving control over a broad range of design parameters (i.e., strains, deformations, ductility factors) most of which are directly estimated at the design stage using advanced analysis tools (a special type of inelastic dynamic analysis). To evaluate the efficiency of the proposed design methodology, it is applied to an actual bridge that was previously designed using a different PBD method, namely displacement-based design accounting for higher mode effects, thus enabling comparison of the alternative PBD approaches. Assessment of the proposed method using nonlinear dynamic analysis for a set of spectrum-compatible motions, indicate that it results in satisfactory performance of the bridge. Comparison with the displacement-based method reveals significant cost reduction, albeit at the expense of increased computational effort.

  • Recently ship safety regulations are being reinforced to improve maritime safety and to prevent maritime pollution by International Maritime Organization. It means that the regulation is becoming more proactive rather than reactive. In the mean time, design philosophy is also moving from rule based design to performance and simulation based design. In this paper, a study on practical application of the damage safety assessment system is carried out. The damage stability and the survivability of a cargo ship that was designed based on current regulation is investigated using performance based design tools in order to improve the safety of the design and verify the performance of the developed damage safety assessment system. To do this, damage scenarios is established and the characteristics and geometry the cargo ship is modeled. A new design alternative is proposed with small change in the internal arrangement based on safety evaluation results of the current design.
