The geotextile have been used in filtration and drainage for over 30 years in many applications of civil and environmental projects. Geotextile tube is compound technology of filtration and drainage property of geotextile. Geotextile have been used for various types of containers, such as small hand-filled sandbags, 3-dimensional fabric forms for concrete paste, large soil and aggregate filled geotextile gabion, prefabricated hydraulically filled containers, and other innovative systems involving containment of soils using geotextile. They are hydraulically filled with dredged materials. It have been applied in coastal protection and scour protection, dewatering method of slurry, and isolation of contaminated material. Recently, geotextile tube technology is no longer alternative construction technique but suitable desired solution. This paper presents the behavior of geotextile tube composite structure by 2-D limit equilibrium and plane strain analysis. 2-D limit equilibrium analysis was performed to evaluate the stability of geotextile tube composite structure for the lateral load and also the plane strain analysis was conducted to determine the design and construction factors. Based on the results of this paper, the three types of geotextile tube composite structure is stable. And the optimum tensile strength of geotextile is 151kN/m and maximum pumping pressure is 22.7kN/m.

The problem of software reuse is dealt in two approaches. One is to build a new software by composing of the built-in components, and the other is to reuse architectural patterns that most of software system is generally composed of. Although the two approaches are important in design of software architecture, we could find outstanding difference in what kind of building blocks they use. The component based software design makes uses of building blocks whose contents are filled in by someone, on the other hand, the architectural pattern based software design is not interested in the contents of building blocks, but in the framework for building blocks including relationship of the building blocks. The paper purposes to find architectural patterns which are commonly found in diverse applications and help software architects reuse them in the software design process. We refine the architectural styles which is the well-known concept for software architecture design, and refine them as architectural components or templates which can be parts of software architecture.

The geotextile tube shall be sewen with geotextile longitudinally in the shape of hose and it shall be filled hydraulically through filling ports at the proper intervals to construct structure. Geotextile container shall be sewen after spreading of geotextile on the split barge and sealed shut after the filling soil, and then moved and positioned at the required position. And the geotextile container passes through the bottom of barge by opening split barge and drops to the seabed to form structure. This structure for the ${\bigcirc}{\bigcirc}$ project, UAE and we would propose that geotextile containment for core material of power plant breakwater to be constructed for lower bunds with containers up to -4.0m and do upper parts with the structures of tube up to 0.0m. For the application of proposed geotextile containment, review on stability of breakwaters and design consideration were adopted. The evaluation on stability of geotextile containment was classified by 3 items, internal design consideration for material selection, reviews on stability for individual and global structure. In this research, the geothermal analysis was performed to estimate the geothermal behavior of central breakwater. Central breakwater is located boundary of intake and outfall channel, it is mean that the central breakwater is thermal boundary of intake low temperature sea water and outfall high temperature sea water. Therefore, it is required to be designed a low permeability to ensure no mix of intake and outfall waters.

In Processing many operations based on distributed environment, it is very important to support the reliability of resources. Providers of resources generally adapt the structure of server-replication to support the reliability of services. Tn server side, it maintains replicas. duplicated server objects. In the structure of this replication, service of stable replica is very important. Therefore the structure to diagnosis the fault of such replica is required. In this Paper, we suggested an effective PUSH fault management algorithm based on PUSH monitoring style of CORBAto overcome weak points of the PULL monitoring style of the replication management system in the distributed object system. Outcomes of the suggested PUSH fault monitoring style were better than other system. We confirmed valuable result in the workloads and timeout-rates.

CBD를 지원하는 소프트웨어 개발기법이 최근 많은 관심과 함께 도입되면서 이를 효과적으로 운용할 수 있는 아키텍처기반의 조립 및 활용분야가 활발히 연구되고 있다. 특히, C2(Chiron-2) 스타일 아키텍처는 GUI를 지원하기 위한 메시지방식의 컴포넌트 조합기법이라는 점에서 많은 관심을 받고 있다. 그러나, 서버측 컴포넌트 모델인 EJB(Enterprise Java Beans)의 경우 쓰레드를 포함할 수 없으며, 직접적인 메소드를 호출하는 방식으로 이하여 GUI 기반 메시지 방식에서는 수정이 불가피하다. 따라서, 본 논문에서는 C2 스타일 아키텍처에 EJB 컴포넌트를 적용할 수 있는 기법을 제안하고자한다. 즉 디자인패턴 중 구조패턴의 하나인 Adapter패턴을 이용하여 EJB 컴포넌트를 C2 프레임워크에 적용할 수 있는 컴포넌트 쓰레드로 생성 및 운영하였다. 이를 위하여, J2EE 1.2.1과 J2SDK1.3환경에서 구현 및 실행하였다.

Black/white comic rendering is one of the researches in the field of non-photorealistic rendering(NPR). Black/white comics have been produced manually as yet. But these previous systems require lots of time and manual work. So we propose the COmics Rendering system on VIdeo Stream (CORVIS) which transforms video streams into black/white comic cuts. Stylized font, one of comic representations, can be used to express onomatopoeic words and mimetic dialogue exaggeratively. But current comic generation systems do not provide enough effects of stylized font. This paper proposes a model for stylized fonts to express various effects. Effects of stylized fonts we proposed include geometric deformations. Thus we could represent stylized fonts on the still cut of movies and the background texture on a cuts of plain black/white comics. The final quality of our system produced is good enough to compare with manual black/white comics.

This writing presents a structural methodology that conceptualize' Fransis Ford Coppola's perspective and adaptation style of his screenplay derived from the author Mario Puzo's original novel "The Godfather". This paper is divided into two different stages: The first stage, namely the "formal stage", encapsulates the analysis of narration and exploring the effects of structural transformations, such as deleting, creating and modifying from the novel to the screenplay. The second stage, entitled "semantic stage", is concerned with ascertaining the difference between the structure itself and the adapter's perspective on the original novel. The opening sequence of will be used as a case study to explore these issues in examining its adaptation style specifically while also offering a template for adapting a screenplay from a novel.

Time series forecasting refers to predicting future time information based on past time information. Accurately predicting future information is crucial because it is used for establishing strategies or making policy decisions in various fields. Recently, a transformer model has been mainly studied for a time series prediction model. However, the existing transformer model has a limitation in that it has an auto-regressive structure in which the output result is input again when the prediction sequence is output. This limitation causes a problem in that accuracy is lowered when predicting a distant time point. This paper proposes a sequential decoding model focusing on the style transformation technique to handle these problems and make more precise time series forecasting. The proposed model has a structure in which the contents of past data are extracted from the transformer-encoder and reflected in the style-based decoder to generate the predictive sequence. Unlike the decoder structure of the conventional auto-regressive transformer, this structure has the advantage of being able to more accurately predict information from a distant view because the prediction sequence is output all at once. As a result of conducting a prediction experiment with various time series datasets with different data characteristics, it was shown that the model presented in this paper has better prediction accuracy than other existing time series prediction models.

Geotextile has been used for various types of containers, such as small hand-filled sandbags, 3-dimensional fabric forms for concrete paste, large soil and aggregate filled geotextile gabion, prefabricated hydraulically filled containers. They are hydraulically filled with dredged materials and have been applied in coastal protection and scour protection, dewatering method of slurry, temporary working platform for bridge construction, temporary embankment for spill way dam construction. Recently, geotextile tube technology is no longer alternative construction technique but suitable desired solution. The paper presents the stability behavior of geotextile tube composite structure by 2-D limit equilibrium and slope stability analysis. 2-D limit equilibrium analysis was performed to evaluate the stability of geotextile tube composite structure to the lateral earth pressure and also transient seepage and stability analysis were conducted to determine the pore pressure distribution by tide variation and slope stability. Based on the results of this paper, the three types of geotextile tube composite structure is stable and also slope stability of overall geotextile tube composite structures is stable with the variation of tidal conditions.
