In environmental studies, decisions are often made on the analytical data indicating certain contaminants as being 'detected' or 'non-detectible.' Since detection limits are analytical method specific, one has to first review the concepts and definitions associated with analytical method systems and specifications. In this study, the experimental analytical values for a series of low level standards (for an ionic species) were used as an example to estimate two different method detection limits (MDL). The scores of EPA's MDL and Pallesen's MDL determined by real analytical scores are 0.0575 and 0.0561 mg/L, respectively for our nitrate data. These scores determined by two different MDL models are roughly similar, while there are apparent differences between two methods with respect to statistical and systematical procedure. However, determination of MDL for one's laboratory provides some practical applications which helps to assure one's regulating authorities that one's measured scores are accurate.

One of the most frequent issues in tunnel excavation is the collapse of rock blocks and the dropping of rock fragments from the tunnel face. The tunnel face can be reinforced using a number of techniques. One of the most popular and affordable solutions is the use of face longitudinal dowels, which has benefits including high strength, flexibility, and ease of cutting. In order to examine the reinforced face, this work shows the longitudinal deformation profile and ground response curve for a tunnel face. This approach is based on assumptions made during the analysis phase of problem solving. By knowing the tunnel face response and dowel behavior, the interaction of two elements can be solved. The rock element equation derived from the rock bolt method is combined with the dowel differential equation to solve the reinforced ground response curve (GRC). With a straightforward and accurate analytical equation, the new differential equation produces the reinforced displacement of the tunnel face at each stage of excavation. With simple equations and a less involved computational process, this approach offers quick and accurate solutions. The FLAC3D simulation has been compared with the suggested analytical approach. A logical error is apparent from the discrepancies between the two solutions. Each component of the equation's effect has also been described.

'Transference phenomenon' is considered as a essential feature in psychotherapy as well as psychoanalysis. But there is much difference in conceptual and methodological issues for 'transference phenomenon' among various psychoanalytical schools. In general, the depth psychological studies for 'transference phenomenon' are mainly from the psychoanalytical view of point but relatively sparse from the analytical psychological view of point which has more holistic and deeper understanding for human psyche. So this article was intended for a comprehensive review of 'transference phenomenon' from the perspective of analytical psychology and tried to make an understanding for its meaning. To begin with, the concept of 'transference phenomenon' was investigated from the view before Jung and after Jung, with Jung's view in the center. Then it was made clear that 'transference phenomenon' from the perspective of analytical psychology could be understood by several characteristic aspects. It was suggested that a careful study on the symbolic meaning of the woodcuts' pictures in Rosarium Philosophorum including a proper interpretation of its posterior part to which Jung didn't refer in "The Psychology of The Transference" be devoted to the genuine understanding of 'transference phenomenon' from the perspective of analytical psychology afterwards.

An eigen-analysis of the coherency matrix provides the polarimetric scattering mechanisms with the matrix characterizing parameters. In this paper, the coherency matrices of deciduous and coniferous vegetation are calculated using the analytical method. The Generalized Rayleigh-Gans approximation is used to model backscattering from distributed coniferous and deciduous leaves. The characteristics of eigen-parameters of simulated coherency matrix for deciduous and coniferous leaves with respect to the leaf shapes and orientations are illustrated.

Design reflects the time and cultural trends and thus can have different symbolic significance and functions depending on the perspective. While this is evident, corporations still insist that designers achieve viewers' complete understanding and satisfaction in their designs. Also, they refuse to accept the designers' interpretation on the grounds that they are subjective and incomplete interpretations even when in fact they are of superior intellectual standard. This problem is also found among the designers dealing with the clients. Thus, as long as all they are willing to accept is the fallibility of each other, the clash between designers and users is inevitable. To solve these problems, we need to have more objective and logical framework for achieving collective understanding on the interpretation of designs and symbols from the very stage of their development. The graphic design is a tangible product that represents the cultural phenomenon and needs to be interpreted as visual symbols. This makes the graphic design a semiological subject. Thus, a semiological approach will enable more analytical interpretations of polysemy of visual symbols. In this light, this study seeks to apply a semiological approach to suggest criteria for interpreting graphic designs as symbols. The criteria will serve as a useful tool for rational evaluation as well as strategic design development.

Shim Dae-Yoon's ChunChuSaJeonSokJeon presented a new direction of the study about ChunChu in Chosun dynasty. It broke the rigid frame for the study about ChunChu in Chosun dynasty and was an experimental challenge trying to interpret ChunChu based on the view of Post-Neo-Confucian. This study is to identify the nature of the Shim Dae-Yoon's interpretation about ChunChu based on the view of Post-Neo-Confucian and to analyze his analytical methodology. Shim Dae-Yoon's interpretation about ChunChu, first of all, newly identified its nature beyond existing Confucian approach. Second, it attempted to approach to the true nature of ChunChu criticizing existing Confucian interpretation as well as differentiating its interpretation methodology. In this approach, Shim Dae-Yoon highlighted the realistic value of ChunChu focusing on the objectivity as a record instead of the absoluteness as a classical text. His study about ChunChu can be evaluated as a significant role in the intellectual history setting up a Post-Neo-Confucian foundation for the study about ChunChu though it failed to structure a complete theoretical frame.

This study intends to understand the visual experience of architectural space generated by users' movement based on the interpretation of visual properties. An analytic theory of Isovist is suggested for the objective and comparable measurement for such visual experience, and a computer program for the analysis has been proposed as well. By using the analytical theory and computer program, eight houses designed by Adolf Loos and Le Corbusler are analyzed for the purpose of understanding the visual characteristics of the Modern Architecture and the contemporaries. The result shows that, while the architectural space of Loos emphasizes personal privacy as for being livable spaces, the architectural space of Corbusier emphasizes users' movement as for including diverse visual arrays. These commensurable results exhibit that the analytical tool and research frame suggested in this study can be a competitive tool for such analysis.

An image analysis was used for the interpretation of microstructures of ferrous metal artifacts. For the purposes, various microstructural features such as average grain size, phase area, shape factor, and composition of the inclusions, were parameterized for the information about manufacturing techniques such as casting, heating and tempering. The carbon content was determined through the evaluation of the amount of pearlite phase. As the amount of pearlite phase increased the shape factor also increased. Grain size was relatively smaller in trans-section than in cross-section. The manufacturing direction was trans-sectional because the orientation of inclusions was elongated lengthwise. All inclusions was of silicate groups and the manufacturing temperature was estimated up to $1450^{\circ}C$.

A new analytical model which can discribe the relationship between the bridging stress and the crack opening displacement was proposed to investigate the microstructural effect on the R-curve behavior in a polycrystalline alumina. The crack opening displacement according to the distance behind the stationary crack tip was measured using in-situ fracture technique in an SEM, and then used for a fitting procedure to obtain the distribution of bridging stress. The current model and an empirical power law relation were introduced into the fitting procedure. The results indicated that the bridging stress function and R-curve computed by the current model were consistent with those computed by the power law relation. The microstructural factor, e.g., the distribution of grain size, was also found to be closely related to the bridging stress. Thus, this model explained well the interaction effect between the distribution of bridging stress and the local-fracture-controlling microstructure, providing important information for the systematic interpretation of microfracture mechanism including R-curve behavior of a monolithic alumina.

In this article, the performance of the THC analyzer was inspected using two different span gases of methane ($CH_4$) and propane ($C_3H_8$). To explore the effect of standard gas selection, MicroFID system was tested by the following procedures. Initially, the system is spanned by propane gas of 60 ppm (or 180 ppmC). The system is then run against methane standards prepared at 5 different concentrations of 200, 250, 300, 400, and 500 ppm. According to the suggestion of the KMOE's test procedure to use multiplying a factor of 3 (for propane), the resulting THC values derived by methane standards were systematically biased with ~500% error relative to true value. This paper discusses the interpretation procedures to obtain the least biased THC values for a given span set-up.
