케이크 여과에서 케이크에 대한 정의가 아직 마련되어 있지 않다. 특히 침전된 플럭(floc)의 여과에서는 케이크를 전혀 정의하지 못하였다. 본 연구에서는 '여과-투과(filtration-permeation)' 실험을 사용하여 모든 경우의 케이크를 명확히 정의하였다. 이 케이크의 정의에 대한 고찰을 통해 케이크 여과에 의해 이룩될 수 있는 케이크 함수량의 한계에 대한 연구를 수행하였다. 여과에 의해 형성된 케이크의 수분 함량을 줄이기 위한 압착조작(expression) 과정을 '고액분리 통합이론'으로 계산하고 실제 압착조작 데이터와 비교하였다. 여과와 압착조작 전체를 분석하여, 압착의 중요성을 검토했다. 그리고 회분식으로 조작되는 필터 프레스의 케이크 배출과 세척시간을 포함하여 가장 효율적인 조작조건을 계산하는 방법을 제안하였다.

We confirm the validity of the analytic expression for the temperature of the Joule heated nano-wire [C.-Y. You et al. Appl. Phys. Lett. 89, 222513 (2006)] with finite element method. The temperature of the Joule heated nano-wire is essential information for the research of the current induced domain wall movement. The analytic expression includes an adjustable parameter which must be determined. Since the physical origin of the adjustable parameter is simplification of the heat source profile, the validity of the analytic expression must be examined for wide range of the nano-wire structure. By comparison with this analytic expression with the results of full numerical finite element method, the adjustable parameter has been determined. The numerically confirmed adjustable parameter values are in the range of 0.60$\sim$0.69, which is well matched with the theoretically expected one. Furthermore, it is found that the adjustable parameter is a slow varying function of the nano-wire geometry. Based on this numerical confirmation, we can apply the analytic expression for the wide range of the nano-wire geometry with proper adjustable parameters.

Background: Maspin expression is a potential prognostic factor for various malignancies but its relation with gallbladder cancer is unknown and needs to be investigated needs to be investigated. We therefore here focused on maspin mRNA expression in normal, gall stone disease and gallbladder cancer subjects, with particular attention to prognostic importance in individuals with malignancies. Materials and Methods: This study was carried out at the Department of Surgical Gastroenterology, King George's Medical University, Lucknow, India. Gallbladder samples from normal (n=25), gall stone disease (n=25) and cancer patients (n=38) were analysed for maspin mRNA expression by semi-quantitative reverse transcriptase PCR and quantitative real time PCR. Statistical analysis was carried out using the Students t test or ANOVA. Survival analysis was conducted according to the Kaplan-Meier method and correlations were assessed using the Pearson correlation method. p<0.05 was considered statistically significant. Results: Significant increase (p=0.028) in expression of maspin mRNA was observed in gallbladder cancer as compared to gall stone disease, whereas no expression was found in normal tissues. Significant correlation (Pearson's coefficient(r)=-0.798, p<0.0001) was observed between relative quantification of maspin mRNA and survival of cancer patients after surgery, with significantly shorter (p=0.002) survival in patients having relative quantification >1.5 as compared to those having relative quantification <1.5. Similarly, significant differences in patient survival for maspin mRNA expression was observed for stage II (p=0.025) and III (p=0.011) cancer. Conclusions: Higher expression of maspin mRNA in gallbladder cancer has prognostic significance for stage II and III cancer, which needs to be investigated further.

본 논문에서는 캐릭터 애니메이션의 효율적인 동작 제어를 위하여 익스프레션을 이용한 애니메이션을 제작하였다. 익스프레션을 이용한 애니메이션은 움직임의 표현에 있어서, 자연스러운 애니메이션을 좀더 쉽고 유용하게 표현하기 위한 방법으로 캐릭터의 동작 제어점들을 분석하여 익스프레션에서 애니메이션을 제어할 수 있는 요소를 찾아 그 식에 사용하였으며, 이것을 토대로 캐릭터의 동작을 자동적으로 제어하는 애니메이션을 구현하였다. 익스프레션에 의한 애니메이션은 간편한 조작으로 자연스럽고 현실적인 움직임을 생성할 수 있다는 익스프레션의 효율성이 장점으로 나타났지만, 애니메이터에 의한 키 프레임 방식에 의한 애니메이션보다는 어색함을 보였다.

We present a latent variable model-based approach to the analysis of gene expression patterns, coupled with topographic clustering. Aspect model, a latent variable model for dyadic data, is applied to extract latent patterns underlying complex variations of gene expression levels. Then a topographic clustering is performed to find coherent groups of genes, based on the extracted latent patterns as well as individual gene expression behaviors. Applied to cell cycle­regulated genes of the yeast Saccharomyces cerevisiae, the proposed method could discover biologically meaningful patterns related with characteristic expression behavior in particular cell cycle phases. In addition, the display of the variation in the composition of these latent patterns on the cluster map provided more facilitated interpretation of the resulting cluster structure. From this, we argue that latent variable models, coupled with topographic clustering, are a promising tool for explorative analysis of gene expression data.

A convolutional neural network (CNN) has been widely used in facial expression recognition (FER) because it can automatically learn discriminative appearance features from an expression image. To make full use of its discriminating capability, this paper suggests a simple but effective method for CNN based FER. Specifically, instead of an original expression image that contains facial appearance only, the expression image with facial geometry visualization is used as input to CNN. In this way, geometric and appearance features could be simultaneously learned, making CNN more discriminative for FER. A simple CNN extension is also presented in this paper, aiming to utilize geometric expression change derived from an expression image sequence. Experimental results on two public datasets (CK+ and MMI) show that CNN using facial geometry visualization clearly outperforms the conventional CNN using facial appearance only.

Tradition is defined as cultural qualities of a regional social group a race, which is transmitted from generation to generation through history. Its contents include human behavior as well as the outcomes from the human behavior and a culture is materialized by means of fullfil fundamental aspiration, in order to co-exist human being and society.This research has considered an architectural space which both show a Korean traditional architecture and modern architectural space, incliding Korean nature under a sort of cultural expression.Also, expressive qualities which are shown within a space as a medium, there is more consideration of method to embody Korean nature into an interior space.There is a subject related to traditional expression of what the real essence of tradition is. In addition, it is a matter of what the method of expression is in order to accomodate, inherit and express the pulse of tradition.

This study investigated the relationship between musical understanding and expression, the purpose of music education. It also intended to present the theoretical basis of integrated early childhood music education by examining into the necessity of it as a method to help young children with musical understanding and expression. The results of the study showed that either of the understanding and expression of music should be necessary and there is a mutual promotional relationship between them. It was found out that real musical understanding can be formed not by mechanical skill, but when the relationship between notes is understood with various experiences. Therefore an integrated early childhood music education became necessary as a principle of educational method to help young children with musical understanding and musical expression. Concretely it was found out to be necessary in terms of the characteristics, interest and concern of young children, the use and development of multi intelligence and the translation of the same knowledge into the same level.
