Electrical resistivity tomography (ERT) is a traditional and representative geophysical method for determining the resistivity distributions of surrounding soil and rock volumes. Depth resolution profiles and sensitivity distribution sections of the resistivities with respect to various electrode configurations are calculated and investigated using numerical model data. Shallow vertical resolution decreases in the order of Wenner, Schlumberger, and dipole-dipole arrays. A high investigable depth in homogeneous medium is calculated to be 0.11-0.19 times the active electrode spacing, but is counterbalanced by a low vertical resolution. For the application of ERT depth resolution profiles and sensitivity distributions, we provide subsurface structure models for two types of land-creping failure (planar and curved), subvertical fracture, and weathered layer over felsic and mafic igneous rocks. The dipole-dipole configuration appears to be most effective for mapping land-creeping failure planes (especially for curved planes), whereas the Wenner array gives the best resolution of soil horizons and shallow structures in the weathered zone.

Fabry disease (FD) is an X-linked lysosomal storage disorder. It is caused by mutations in the α-galactosidase A gene, which results in deficient or absent activity of α-galactosidase A (α-Gal A). This leads to a progressive accumulation of globotriaosylceramide (Gb3) in various tissues. Manifestations of Fabry disease include serious and progressive impairment of renal and cardiac function. In addition, patients experience pain, gastrointestinal disturbance, transient ischaemic attacks, and strokes. Additional effects on the skin, eyes, ears, lungs, and bones are often seen. Reduced life expectancy and deadly consequences are being caused by cardiac involvement. Chaperone therapy or enzyme replacement therapy (ERT) are two disease-specific treatments for FD. Thus, early detection of FD is critical for decreasing morbidity and mortality. Globotriaosysphingosine (lyso-Gb3) for identifying atypical FD variants and highly sensitive troponin T (hsTNT) for detecting cardiac involvement are both significant diagnostic indicators. This review aimed to offer a basic resource for the early diagnosis and update on the diagnosis of having FD. We will also provide a general diagnostic algorithm and information on ERT and its accompanying treatments.

Microcracks that consist of quarry planes of granite are an essential factor affecting the long-term behavior of granite. In this paper, fine-grained granite distributed in the Tsukuba area of Japan was selected and microcracks were measured by using scanline method. In addition, a new relaxation testing equipment was developed to carry out stress relaxation test under water-saturated triaxial condition. Based on the relaxation test results with the initial stress level of 75%, the axial stress is decreased by 39%-49% just after the start of the tests, and the totally relaxed stress is 10∼24 MPa in 190 ERT (Elapsed relaxation time, hour). In addition, the relaxed stress is increased with the density of cracks which are parallel to axial load direction.

Art deco means decorative form on the base of cubism which has widely spread from 1910's to 1930's. Also it pursued the rational & functional design even than deecoration of art nouvear, and colorful combination of fauvism. The analytical study on design included occurrence, developing process and formative features expressed in the art deco fashion. The changes of the art deco style, it referred to the fashion illustration which was the Graphic-s of Ert in 19 century. Besides analysised activity designer in the art deco style, at the same time considered fashion design as comparable analysis. Paul Poiret, a representative french designer, contributed to the clothing culture which accepted oriental influence and it was all the fashion enough to call the originator of present fashion. He did away with the corset, relaxed the waistline, and freed the body from clothing constrictions of almost a hundred years. Since 1914, because of industry of woman clothing that art deco represent concern of one's Chanel's perennial rival in the firmanent of parisian high fashion was the Italian designers, Elsa Schiaparelli, Schiaparelli's originalily was profoundly influenced by the avant-garde art of the time ; Da da and Surealism were principal soures of new ideas. It apply the style to geometrical or abstract form impressed straight and smooth line on suitable technic. Such inflection of art deco heralded a close collaboration between the artist-jeweller and the fashion industry. Especially, jewelry designers were fond of juxtaposing transparent faceted stoned which reflected the light, with matt stones, which offered rare or unconventional contrasts through their opacity. Consequently, art deco will exert value of utility for the progressive fashion & jewel CAD through continuous research.

Bed-soils can be used to help plants to overcome unfavorable conditions of soils, especially hydraulic properties of soils. This study was conducted to evaluate the effect of organic and inorganic raw materials on saturated hydraulic conductivity ($K_s$) of bed-soils. Perlite and bottom ash, which are inorganic materials, increased more $K_s$ of bed-soils than coco peat, an organic material. However, vermiculite, an inorganic material, increased less than coco peat. Saturated hydraulic conductivity of bed-soil mixed with fine vermiculite ($0.14{\pm}0.02mh^{-1}$) was much lower than one containing coarse vermiculite ($0.85{\pm}0.21mh^{-1}$). Such effect was more apparent when pressure was added on bed-soils containing fine vermiculite ($0.07{\pm}0.01mh^{-1}$), probably reflecting the decrease in pore size with the expansion of vermiculite wetted. Compacting decreased more $K_s$ in the bed-soils containing coco peat or vermiculite than other mixtures. Those results suggest that perlite and bottom ash in bed-soils play an important role in improving saturated hydraulic conductivity but vermiculite in bed-soils may suppress the improvement of saturated hydraulic conductivity with the decrease of its size and with the increase of compacting pressure.

This study aims to find out the growth characteristics of riparian plants on the artificial floating islands (AFI). Three types of experiments were performed. The vegetation growth were compared by the plant-supporting materials; natural cotton mat, coir mat on the AFI or in the water, and natural soil at the waterfront. Major findings are; 1. The survival rate of riparian plants was 100% on both coir-mat and cotton-matislands, which implies that we may substitute cheaper cotton for expensive coir-mat. 2. Both natural cotton mat and coir mat were good for the growth of plants. Especially, the natural cotton mat was good for Sparganium stoloniferum and Miscanthus sacchariflorus, and the coir mat was good for Typha latifolia. 3. The growth rate of stem and root showed difference between the stem-removed plants and stem-remaining plants. As a whole, the growth rate of stem-removed plants was bigger than the one of stem-remaining plants. 4. The growth rate of plants showed difference between those grown on the AFI and those grown in the water. The growth rate of plant on the AFI was bigger than the one in the water. 5. The growth rate of plants on the AFI was bigger than the one on the natural soil at the waterfront.

Remote sensing data has been widely used in the estimation of crop yields by employing statistical methods such as regression model. Machine learning, which is an efficient empirical method for classification and prediction, is another approach to crop yield estimation. This paper described the corn yield estimation in Iowa State using four machine learning approaches such as SVM (Support Vector Machine), RF (Random Forest), ERT (Extremely Randomized Trees) and DL (Deep Learning). Also, comparisons of the validation statistics among them were presented. To examine the seasonal sensitivities of the corn yields, three period groups were set up: (1) MJJAS (May to September), (2) JA (July and August) and (3) OC (optimal combination of month). In overall, the DL method showed the highest accuracies in terms of the correlation coefficient for the three period groups. The accuracies were relatively favorable in the OC group, which indicates the optimal combination of month can be significant in statistical modeling of crop yields. The differences between our predictions and USDA (United States Department of Agriculture) statistics were about 6-8 %, which shows the machine learning approaches can be a viable option for crop yield modeling. In particular, the DL showed more stable results by overcoming the overfitting problem of generic machine learning methods.

The purpose of this study is to examine the medicalizing process of menopanse with literature review, and then is to explore the knowledge of 'menopausal syndrome' critically, focused on four critics on the biomedical model which were suggested by Mishler. Although menopause is a natural biological phenomenon, the view of many medical researchers and practitioners is that menopause is a disease. After synthetic estrogen was developel in 1938, physicians did agree on two basic assumptions : menopausal women should be managed by physicians, and medical intervention should be given. Menopouse was defined as a deficiency disease (estrogen difficiency) by Wilson in 60's and is redefined as a cause of disease(for example, osteoporosis, heart disease) at the present. But the other view of non-medical researcher is that 'menopausal syndrome' as a disease is constructed medically. It was reported that Only hot flush and sweating of physical symptoms experienced by menopausal women, were associated with menopause. Symptoms of menopausal syndrome are also related with symptons of aging. So, it cann't conclude that menopausal syndrome is resulted from menopause, and it cann't be only explained that menopausal syndrome is related causally to estrogen deficiency, and only treatment by ERT or HRT is best relevant. It cann't assume that menopausal syndrome is a common phenomenon to all menopause women, because culture affected on women's experience of menopause.

Even though there is no doubt that ERP(Enterprise Resource Planing) system is a prevailing solution for integrating corporate information, many companies still hesitate adopting ERP system because of a great deal of cost including maintenance cost. In special, unless consulting knowledge that is infused into process reengineering phase or adequately embedded in customized ERP system is upgraded on time, then we cannot guarantee the optimality of system performance. Hence, this paper aims to construct an ERP system that adapts itself to environmental changes that are issued by database and users. To do so, we adopt intelligent agent technology and Petri net theory. The agents autonomously cooperate each other to investigate databases and to find any exceptional changes and analyze how the changes will affect ERP performance. The dynamics of the agents are represented as Petri nets. The newly proposed ERP system is to make corresponding BPR processes maintain optimality. To show the feasibility of the proposed ERP maintenance system, logistics component is described as an illustrative example.
