  • Two-level factorial designs are popular in industry due to their simplicity, efficiency, graphical interpretation, and flexibility in sequential experimentation. However, experimenters are often frustrated when they have factors with more than two levels. There have been some works on design of experiments with two- and four-level factors, which mostly deal with qualitative four-level factors. This paper discusses differences between qualitative and quantitative four-level factors. Optimal designs are provided for some designs with four-level quantitative and two-level factors.

  • Most design practices have not taken advantage of the advanced theories in the modern fracture mechanics and finite element analysis due to complexity of analysis as well as the large quantity of vaguely defined parameters in actual designs. This paper considers fatigue problems in bridge structures using effective analytical and design tools from the field of qualitative constraint reasoning. A set of software modules was developed for fatigue analysis ,and evaluation, which is easily applicable in engineering practices of bridge designers. The software modules integrate techniques in the field of knowledge representation and qualitative reasoning, into the conventional fatigue analysis. The techniques enable the use complex analysis formulations to tackle practical problems with uncertainties, and present the design outcome in two-dimensional design space. Appropriate engineering assumptions and judgments in carrying out these procedures, often the most difficult part for practicing engineers, can be partially produced by using qualitative reasoning to define the trends and ranges, interval constraint analysis to derive the controlling parameters, as well as design space to account for practical experience. This paper depicts a way of complex analysis to practical engineering designs with qualitative reasoning.

  • There is currently a focus on usability of interactive computer software. Previous research in software ergonomics has indicated the importance of evaluating the usability of software user interfaces. Software developers, interface designers or human foctors engineers often confront the task of comparative evaluation among systems, versions or interface designs. This study presents a structured model for comparative evaluation of user interface designs using usability criteria and measures. The proposed model consists of twomain phases : the prescreening phase ad the evaluation phase. The first phase involves expert judgment-based approach with qualitative criteria. The prescreening phase uses absolute measurement analytic hierarchy process to filter possible altermative interfaces to a reasonable subset. The second phase involves user-based approach such as usability testing, with quantitative criteria. The objective of the evaluation phase is to evaluate a subset of altermatives using objective measures. A set of criteria and measures for evaluating the usability of computer software designs is presented. The proposed model provides practitioners with a structured approach to select the best interface based on usability criteria and measures.

  • Purpose: The purpose of this study was to compare similarities and differences in research trends for community health nursing between Korea and Japan. Methods: Comparison was made in terms of research design, data collection and sampling method, and key concepts from community health nursing research by literature review. We analyzed original articles from representative Journals covering community health nursing research from 2004 to 2008. Results: We found that research design was quite different between the two countries. Quantitative research design was dominant in Korea, while qualitative and qualitative research designs were used equally in Japan. In particular, outcome research was found only in Korean papers. Conclusion: Based on the comparison, the following recommendations are suggested related to the strengths and weaknesses of research concepts and methods observed in each country. It is suggested that future collaboration should be undertaken especially to improve the diversity of research design and method. More diverse research designs should be used in both countries. Particularly in today‘s aged society, evidence-based research and outcome research are needed for community health nursing in both countries.

  • This paper proposes the newly developed a classification scheme for Management of Technology (MOT) research, by analyzing research papers published in major academic journals of MOT. To refine our proposed classification, we conducted a contents analysis after collecting 696 papers published in 11 major international journals and 2 representative domestic journals including Journal of Korean Technology Innovation Society, from 2006 to 2012. Our findings show that this classification scheme is composed of total 8 methodologies within each research design such as conceptual qualitative, empirical qualitative, conceptual quantitative, and conceptual quantitative researches. In addition, we provide research reviews based on characteristics between 1) domestic and foreign researchers, 2) domestic and international journals, and 3) different major domestic journals as follows. Firstly, the underlying trends of research design and methodologies in MOT research are concentrated in empirical studies regardless of the origin of researchers and journals. However, the proportion of theoretical discussion in the international journals is higher than that of theoretical discussion in the domestic journals. Secondly, there are many more empirical qualitative researches and archival researches written in the Journal of Korean Technology Innovation Society, whereas the proportion of empirical quantitative research and conceptual research published in the Journal of Technology Innovation is higher than that. From the results, this paper will contribute to choosing research designs and methodologies more suitable to research purpose for future MOT researchers and provide the direction for concrete systematic approach on research designs and methodologies.

  • The historicism and romanticism of John Galliano's designs are rivaled only by the spectacular and theatrical nature of his fashion shows; romantic silhouette, the complexity of the cut and, of course, the painstaking attention to historical detail. Galliano's approach is very much that of a British designer in that he absorbs wildly diverging historical and cultural elements to invent new hybridizations of the contemporary. Galliano started his career as part of the wildly uninhibited avant-garde London design scene. His designs were twisted and artfully torn, weired and also beautiful. The purpose of this study is to investigate the Comic Expression depicted on John Galliano's works by borrowing the Comic. The Comic or the Comedy is a kind of art form that signifies exciting effects, and so, is a means of raising a laugh. The similar concepts of the Comic already were depicted by means of transformation and distortion of form, satire, fantastic pastiche and reversion of substances on Cubism, Dada, Surrealism, Pop Art and Postmodernism. Therefore, John Galliano selected the quixotic expressional methods to seek for having playful fun. The aesthetics of the Comic is the beauty based on quantitative or qualitative contradiction between expectations and realizations. That is, the Comic is characterized by getting rid of stress through laugh with clarifying a subject of contradiction. This study found that John Galliano's designs are expressed the quixotic comic on Historical image, Exotic image and Primitive image to make a complaint against the social evils.
