Blast severity data of 39 rice varieties at 11 sites in Korea from 1997 to 1999 were analyzed using AMMI model and pattern analysis. Genotype x Environment (G$\times$E) interaction sum of squares (SS) accounted for 12 % of the total SS. Eight genotype groups and seven location groups were identified based on blast reaction pattern. The data obtained from over 21 sites with 44 test varieties from 1981 to 1996 were also considered. These were compared with the 1997-1999 data using the G$\times$E analysis results. Majority of the variability in the Korean Rice Blast Nursery (KRBN) were attributable to variations due to genotypes. Variations of G$\times$E interaction were maintained though test sites were reduced from 21 to 11 sites. Broadly compatible biological discriminative varieties identified were Nagdongbyeo and Akibare while broadly incompatible biological discriminative varieties identified were Hangangchalbyeo and Seogwangbyeo. Key sites for future evaluation work could be selected from location groups. Each location group should be represented by the site with the strongest interaction pattern. Blast responses in Cheolwon, Gyehwa, Suwon, Iksan, and Icheon showed different patterns from other locations.

Objectives : Huangyuanyu's interpretation of the six channel diseases of the Shanghanlun were examined based on contents on the six channel qi metabolism theory in his works, Shanghanxuanjie, Shanghanshuoyi, and Sishengxinyuan. Methods : Contents related to the six channel qi metabolism theory in the Shanghanxuanjie, Shanghanshuoyi, and Sishengxinyuan were extracted and examined to identify a fundamental principle from the perspective of the six channel qi metabolism theory. Characteristics of each of the six channel diseases were organized. Results : Huang's understanding of the six channel diseases in the Shanghanlun could be summarized by the six channel. Its features could be explained as following. First, in examining the principles of the controlling qi[司氣] and constitutionally influenced transformation[從化], the rise and fall of the body's yang qi was emphasized. Second, center qi[中氣] was considered important, the taiyin Spleen being the key to life and death. Third, the pathology of 'earth dampness/water cold/wood stagnation' due to weakness of the center qi was suggested. Fourth, the principle of boosting-yang-suppressing-yin was emphasized in treatment, with criticism of the nurturing-yin-extinguishing-fire method. Conclusions : In understanding the six channel diseases in the Shanghanlun, Huangyuanyu focused on the body's yang qi and center qi based on key theories such as the 'five circuits and six qi' and 'six channel qi metabolism' theories. His perspective could be helpful in understanding Zhangzhongjing's work more comprehensively.

Data modelling and interpretation for structural health monitoring (SHM) field data are critical for evaluating structural performance and quantifying the vulnerability of infrastructure systems. In order to improve the data modelling accuracy, and extend the application range from data regression analysis to out-of-sample forecasting analysis, an improved most likely heteroscedastic Gaussian process (iMLHGP) methodology is proposed in this study by the incorporation of the outof-sample forecasting algorithm. The proposed iMLHGP method overcomes this limitation of constant variance of Gaussian process (GP), and can be used for estimating non-stationary typhoon-induced response statistics with high volatility. The first attempt at performing data regression and forecasting analysis on structural responses using the proposed iMLHGP method has been presented by applying it to real-world filed SHM data from an instrumented cable-stay bridge during typhoon events. Uncertainty quantification and correlation analysis were also carried out to investigate the influence of typhoons on bridge strain data. Results show that the iMLHGP method has high accuracy in both regression and out-of-sample forecasting. The iMLHGP framework takes both data heteroscedasticity and accurate analytical processing of noise variance (replace with a point estimation on the most likely value) into account to avoid the intensive computational effort. According to uncertainty quantification and correlation analysis results, the uncertainties of strain measurements are affected by both traffic and wind speed. The overall change of bridge strain is affected by temperature, and the local fluctuation is greatly affected by wind speed in typhoon conditions.

Purpose: This study reviewed what the location of death (LOD) means as an outcome and how to use LOD to assess end-of-life (EOL) care. This study also examined the reason why LOD is significant for the quality of EOL care. Methods: A literature review was performed, using LODs and home deaths as outcomes in the field of EOL care, and analyzed the findings associated with key fields in regards to LOD. Results: Palliative care research used LOD, in particular, hospital death (versus home death) as a significant outcome when examining cost savings, quality of life care, and patient and family preferences. Based on substantial evidence from previous research, home hospice or continuous palliative care in non-hospital settings (i.e. homes, nursing homes) have been designed and available for dying patients in developed countries. Conclusion: The LOD delivers practical significance as an outcome for diverse reasons. In-depth examination on LOD in South Korea is needed despite limitations to interpretation of its meaning in the country.

This paper reviews the relationships between diverse ecological design strategies and competing conceptions of ecological approach in place making. It focuses conceptual trends of what we categorize a building "green" and outlines a social constructive perspective on the development of sustainable architecture. This study classifies seven logics of ecological design-eco-technical, eco-aesthetical, eco-social, eco-medical, eco-renewable, eco-cultural, eco-central - which have their roots in competing philosophies of environmentalism. In my analysis of the logics concerning sustainable architecture, the adapted and incorporated technology from high-tech to low-tech levels is a key issue. These points lead us to propose a way that each logic configures the technological approaches and alternative visions of sustainable places. This paper discusses the implications of the competent nature of plural ecological design perspectives for architectural education, practice, and researches.

Genetic networks are a key to unraveling dynamic properties of biological processes and regulation of genes plays an essential role in dynamic behavior of the genetic networks. A popular characterization of regulation of the gene is a kinetic model. However, many kinetic parameters in the genetic regulation have not been available. To overcome this difficulty, in this report, state-space approach to modeling gene regulation is presented. Second-order systems are used to characterize gene regulation. Interpretation of coefficients in the second order systems as resistance, capacitance and inductance is studied. The mathematical methods for transient response analysis of gene regulation to external perturbation are investigated. Criterion for classifying gene into three categories: underdamped, overdamped and critical damped is discussed. The proposed models are applied to yeast cell cycle gene expression data.

Herbal medicine is the use of medicinal plants for prevention and treatment of diseases: it ranges from traditional and popular medicines of every country to the use of standardized and tritated herbal extracts. Generally cultural rootedness enduring and widespread use in a traditional medical system may indicate safety, but also efficacy of treatments, especially in herbal medicine where tradition is almost completely based on remedies containing active principles at very low and ultra low concentrations or relying on magical-energetic principles. The efficacy and safety assessments of medicines, whether modern or herbal, invariably encounter challenges or problems during the course of pre-clinical and clinical research. Some of the challenges in evidence-based herbal medicinal research are unique, and the researcher must be cognizant of them in order to safeguard the quality of the data obtained. Key challenges are: the quality of raw materials; appropriateness of biological/pharmacological activity assessment methodology, and data interpretation; standardization methodology; pharmacokinetics and bioavailability of active constituents and metabolites; clinical dosage formulation/production; and clinical study designs and outcome measures.

This study investigated the key role of sketches in creative fashion design by observing the cognitive process of idea development through a professional's design problem solving using the medium of hand sketching. The three-part semi-constrained design experiment with a professional designer, in which the participant designer was provided a source of inspiration image and asked to design a small collection of outfits, identified a fashion designer's idea development process as involving two phases of sketch processes: lateral and vertical transformation. Analysis of the video/audio recording and corresponding interviews validated lateral transformation in the designer's use of sketches to represent interpretation of the provided inspiration source. Through sketching, the designer transferred fuzzy ideas onto paper. Vertical transformation was observed through the designer's modification of previous ideas after reflecting on earlier sketches, with various ideas divided, manipulated, discarded, regrouped, and combined through sketching activities. The designer's sketching process is valuable design knowledge that facilitates the idea development process and ultimately triggers generation of creative ideas. Understanding it may benefit practitioners and educators.

Vibration-based structural identification has become an important tool for structural health monitoring and safety evaluation. However, various kinds of uncertainties (e.g., observation noise) involved in the field test data obstruct automation system identification for accurate and fast structural safety evaluation. A practical way including a data preprocessing procedure and a vector backward auto-regressive (VBAR) method has been investigated for practical bridge identification. The data preprocessing procedure serves to improve the data quality, which consists of multi-level uncertainty mitigation techniques. The VBAR method provides a determinative way to automatically distinguish structural modes from extraneous modes arising from uncertainty. Ambient test data of a cantilever beam is investigated to demonstrate how the proposed method automatically interprets vibration data for structural modal estimation. Especially, structural identification of a truss bridge using field test data is also performed to study the effectiveness of the proposed method for real bridge identification.
