Background: Quantitative evaluation of renal cortical echogenicity (RCE) has been tried and developed in human and veterinary medicine. Objectives: The objective of this study was to propose a method for evaluating RCE quantitatively and intuitively, and to determine associations between ultrasonographic renal structural distinction and estimated glomerular filtration rate (eGFR) in canine chronic kidney disease (CKD). Methods: Data were collected on 63 dogs, including 27 with normal kidney function and 36 CKD patients. Symmetric dimethylarginine and creatinine concentrations were measured for calculating eGFR. RCE was evaluated as 3 grades on ultrasonography images according to the distinction between the renal cortex and outer medulla. The RCE grade of each kidney was measured. Results: There was a significant difference in eGFR between the group normal and CKD (p < 0.001). As mean of RCE grades (the mean values of each right and left kidney's RCE grade) increases, the proportion of group CKD among the patients in each grade increases (p < 0.001). Also, severity of RCE (classified as "high" if any right or left kidney evaluated as RCE grade 3, "low" otherwise) and eGFR is good indicator for predicting group CKD (p < 0.001). Conclusions: The degree of distinction between the renal cortex and the outer medulla is closely related to renal function including eGFR and the RCE grade defined in this study can be used as a method of objectively evaluating RCE.

Recently, as film has been admitted as the artistic merit and higher value-added business, the past studies on film have been lively carried on various fields. Especially, the film business is thought to be value-added business and has explored the causes of influencing spectators. However, there are no researches enough to explain what induces the choice and diffusion of the film. The film is not only hedonic products but also typical example of experiential products. So how to process film formation plays important roles in explaining the procedures of forming preference on the film and the movies spread more widely. But the great part of study of films has been concentrated on exploring hedonic factors of influencing spectator's choice. Until now there is not enough study for the relationship between experiential information processing and film preference. To explain film's preference, our study focuses on preference fluency and processing fluency that can provide an insight for our question about the relationship. In this article, to explain the procedures of processing experiential information and forming preference on the film, our study focuses on finding the relationship between film's processing fluency and film's preference fluency and explores the factors that affect film's processing fluency. To achieve the goal of this study, we distinguish factors of film's conceptual fluency from factors of film's perceptual fluency and explore the paths from the factors to film's preference fluency. The factors which have effects on perceptual fluency are hypothesized to be distinction of image expression, distinction of sound expression, correspondence between actors' image and their role. The factors which have effect on conceptual fluency are supposed to be well-organized story, suitability of lines expression. The experiments in which students were sampled at 'C' university were conducted in 2010 (december). Data collection was proceeded through questionnaires. We test the hypothesized model by using structural equation modeling(Amos 17.0). The fit indices for the model are as follows : x²=416.266(df=213, p=0.00), GFI=0.855, AGFI=0.812, RMSEA =0.069, IFI=O.925, CFI=0.920, TLI=0.905. According to the guidelines, there is evidence that our measurement model fits data. The results of empirical study are as follows. The path from film's perceptual fluency to film's preference fluency is supported(estimate: 0.223, C.R: 2.641). The path from film's conceptual fluency to film's preference fluency is supported(estimate: 0.397, C.R: 4.863). The path from distinction of image expression to film's perceptual fluency is not supported(estimate: 0.113, C.R: 1.665). The path from distinction of sound expression to film's perceptual fluency is supported (estimate: 0.190, C.R: 2.042). The path from correspondence between actors' image and their role to film's perceptual fluency is supported(estimate: 0.686, C.R: 5.566). The path from well-organized story to film's conceptual fluency is supported(estimate: 0.396, C.R: 4.023). The path from suitability of lines expression to film's conceptual fluency is supported(estimate: 0.536, C.R: 5.441). Concludingly, our study explored the influencing factors of film's processing fluency inducing film's Preference fluency. First, film's perceptual fluency and film's conceptual fluency have positive effects on film's preference fluency. Second, distinction of image expression is not significant on film's perceptual fluency, but distinction of sound expression and image's correspondence of actors' image and their role have positive effects on film's perceptual fluency. Lastly, well-organized story and suitability of lines expression have positive effects on film's conceptual fluency.

Herbal medicines have been used since ancient times as medicines to treat and relieve the symptoms of many different human diseases. However, so far, relatively few herbal medicines have been evaluated scientifically to prove their safety, potential benefits and effectiveness. This study was conducted to provide the groundwork for improving the current registration regulations for herbal medicines in distinction from synthetic medicines. The study was performed based on the literature research and individual interviews with 5 experts who had extensive experience in registration of herbal medicines. When compared with synthetic drugs, herbal medicines exhibit some marked differences, namely the active principles are frequently unknown, standardization, stability and quality control are not easy, they are usually mixtures of complex compounds. Second, the current regulations for herbal medicines are reviewed by comparison of foreign regulation systems like the one in China. The regulation requirements of herbal medicine in China are in distinction from synthetic drugs. The authors conclude that new registration requirements for the herbal medicines should be changed as follows; the toxicity and efficacy data should be submitted as mixed herbal preparation and the documents and other research on the reproduction and generation toxicity need to be shown for the proof of reproduction and generation toxicity, if needed.

The cytological distinction of carcinoma cells from reactive mesothelial cells in serous effusions nay be difficult or imposslble based on morphology alone, especially In specimens containing reactive mesothelial cells which form glandular or ball- or papillary-shaped conglomerates or which mimic malignant nuclear features. Calretinin is a newly reported immunocytochemical marker for mesothelial cells, which can potentially be utilized for facilitating this distinction. This study evaluated the usefulness of calretinin for the discrimination between reactive mesothelial and metastatic carcinoma cells in serous effusion. Immunocytochemical staining was undertaken on 33 benign reactive and 87 malignant serous effusion specimens with histologically confirmed diagnoses. The specimens including smears and cell blocks were stained with polyclonal antibody to calretinin by labelled streptavidin-biotin method. The positive expression of calretinin was noted In 32(97.0%) of 33 benign reactive effusions and 9(10.3%) of 87 malignant effusions. The sensitivity and specificity of the calretinin immunostaining for reactive mesothelial cells was 97.0% and 89.7%, respectively. In conclusion, calretinin is a useful marker for distinguishing between reactive mesothelial cells and carcinoma cells in serous effusions.

In order to provide a better understanding about the phenomenon of KM assimilation, this study attempts to conceptually develop and empirically compare two different models: (1) the first model, which considers the KM process as the flow of knowledge that plays an intervening role between knowledge stocks (i.e., knowledge worker, technical knowledge infrastructure, external knowledge linkage, knowledge strategy, and internal knowledge climate) and the level of KM assimilation; and (2) the second model is a simple direct effect formulation without any distinction between knowledge stock and flow. These two models were then tested and compared using the responses of 187 Korean organizations that had already implemented enterprise-wide KM systems. The findings indicate that the two models are useful in explaining successful KM assimilation. However, the first causal model with the distinction between knowledge stock and flow assesses the effectiveness of KM more accurately than the second model without the distinction. Interestingly, the KM process was shown to be the most critical factor for the proliferation of KM activities across an organization. The findings of this study are expected to serve not only as early groundwork for researchers hoping to understand KM and its effective assimilation in organizations, but should also provide practitioners with guidelines as to how they can enhance their KM assimilation level so as to improve their organizational performance.

The present thesis examines the correlation of VOT and F0 in the three-way distinction of Korean obstruents, conducting production and perception tests. In the production test, one female native speaker of Korean with a Seoul dialect (the author) recorded 15 repetitions of a monosyllabic word list including /ka, kha, k*a, pa, pha, p*a, ta, tha, t*a, ca, cha, c*a/ in random order, VOT and F0 of the following vowels were measured, and the result was significant for the three-way distinction with a strong correlation between VOT and F0, and also in the VOT-F0 plot, no overlapping among the domains was observed. As for the perception test, I manipulated the data recorded in the production test, heightening or lowering their F0 values. In all, 14 subjects (seven males and seven females) participated in the identification test. The result was as follows: the fortis stimuli were not influenced by F0 changes, and the VOT and F0 values at the lenis-aspirated boundary were negatively correlated. From these results I concluded the following: 1) VOT and F0 can distinguish the three domains of Korean obstruents without overlapping; 2) the fortis perception does not need F0 as its acoustic cue; and 3) VOT and F0 in the distinction between the lenis and aspirated are in the phonetic trading relation[2].

There are two methods to make a distinction of deterioration of high-speed railway track. One is that an administrator checks for each attribute value of track induction data represented in graph and determines whether maintenance is needed or not. The other is that an administrator checks for monthly trend of attribute value of the corresponding section and determines whether maintenance is needed or not. But these methods have a weak point that it takes longer times to make decisions as the amount of track induction data increases. As a field of artificial intelligence, the method that a computer makes a distinction of deterioration of high-speed railway track automatically is based on machine learning. Types of machine learning algorism are classified into four type: supervised learning, unsupervised learning, semi-supervised learning, and reinforcement learning. This research uses supervised learning that analogizes a separating function form training data. The method suggested in this research uses SVM classifier which is a main type of supervised learning and shows higher efficiency binary classification problem. and it grasps the difference between two groups of data and makes a distinction of deterioration of high-speed railway track.

This study analyzes how social environment influenced underclothes and characteristic which underclothes have is associated with the outer garment and the underclothes in the Middle Ages. As a result, 1 can get the next conclusion First, throughout the Middle Ages, body was involved with the sense of same and sin influenced by the religious austerity. This mentality was applied to the underclothes. As underclothes are not generally revealed, it is recognized to be not important but inefficient. Second, in the late Middle Ages, as the outer garment reveal the body line, the underclothes are affected by it. So men's and women's distinction in the outer garment is applied to the underclothes. In the second quarter of the 14C, class distinction and sexual attraction certainly present on the outer garment but are not applied to the underclothes. The conceptions that underclothes might express the spirit of the changing times, in sympathy with the outer garment, did not enter the medieval mind. Third, the function to protect the body is emphasized the underclothing in the Middle Ages, whereas it was important to identify rank sign in the history of underclothes. Throughout the Middle Ages the underclothing of both sexes is emphasized utilitarian in (unction rather than class distinction and sexual attraction. But women exposed their body line in thin chemise to represent sexual attraction in the late Middle Ages.
