공동작업을 위한 어플리케이션 공유는 분산되어 있는 개발도구와 어플리케이션을 공유하여 다수의 참여자가 환경적으로 제약받지 않고 공동 개발할 수 있도록 한다. 그러나 CVE(Collaborative Virtual Environment)에 기존의 어플리케이션 공유방식을 적용하기에는 기존 방식의 3차원이라는 공간적인 요소를 고려하지 않고 자유스런 상호작용을 방해한다는 문제점을 가지고 된다. 이 연구에서는 이러한 문제점들을 해결하여 CVE(에서 효과적으로 어플리케이션을 공유하기 위한 3차원 가상환경에서 공동작업을 위한 어플리케이션 공유 시스템을 설계하였다. 설계된 시스템은 어플리케이션 공유 관리기와 그룹 관리자와 통신 관리자로 구성하였다. 시스템은 참여자 사이트로 이동하는 에이전트에 의해 가상 환경에서 참여자의 어플리케이션에 대한 3차원상의 이벤트를 감지할 수 있고 스케줄링에 의해 참여자간의 충돌을 해결할 수 있다. 다라서 설계한 가상환경 공동작업을 위한 어플리케이션 공유 시스템은 가상환경을 위한 ,CSCW응용 개발 시, 기존 윈도우 어플리케이션을 3차원 가상환경에서 쉽게 공동 사용할 수 있도록 함으로써 효율적인 공동 작업을 지원하고 기존 어플리케이션 소프트웨어의 재사용성을 높일 수 있다.

This study was conducted to test the effect of residual Al on plankton community after dissolved air flotation (DAF) application. Growth rate of phytoplankton after DAF application ($0.37day^{-1}$) was about 2 times lower than that before DAF application ($0.70day^{-1}$). Under the condition of addition of nitrogen and phosphorus without light, growth rate phytoplankton in treatment without residual Al increased in difference with showing the negative growth rate in treatment with residual Al. Under the condition of light without addition of nutrient, growth rate of phytoplankton was no noticeable difference between the before and after DAF application. The relatively high settling rate (0.47 m/day) was observed in treatment after DAF application. Although the abundance of rotifer decreased, the abundance of copepod and cladoceran such as Daphnia galeata, Diaphanosoma sp. and Bosmina longirostris with relative higher grazing was no noticeable difference between the before and after DAF application. In the treatments before and after DAF application with zooplankton, growth rate of phytoplankton was $0.41{\pm}0.08day^{-1}$, $0.20{\pm}0.03day^{-1}$, respectively. This difference was in treatment after DAF application similar with those in treatments before and after DAF application without zooplankton. Those indicate that the filter-feeding effect of zooplankton on phytoplankton community may be not changed by residual Al after the DAF application. These results suggest that residual Al after DAF application be to improve water quality by inhibition of growth rate as well as increasing settling rate of phytoplankton.

최근 가상화 기술은 데스크탑 환경에서 모바일 플랫폼 환경으로 그 자리를 옮겨 개인과 기업, 그리고 학계 등 안전하지 않은 보안 환경과, 여러 사람들의 공유하는 팀 환경에서 많은 변화를 가져오고 있다. 이 환경에서 대표적인 것은 Vmware의 MVP솔루션들과 Enterproid의 Divide이다. 하지만 이러한 모바일 가상화 기술환경에서 또다른 이슈가 되고 있는 것은 한정된 자원과 성능상의 제약들인데 그것을 어플리케이션 가상화 기술로 모바일 플랫폼의 약점을 개선하려는 방안으로서 대두되고 있다. 본 논문에서는 기존에 제안되었던 로컬 기반 데스크탑용 어플리케이션 가상화 구조를 안드로이드 환경으로 가져와 데스크탑 환경 어플리케이션 가상화의 한계점인 사용자 영역구분, 프로그램 실행시 생기던 할당 자원증가를 안드로이드 어플리케이션 가상화 런처를 통해 개선하였다.

The current network environment is composed of heterogeneous H/W and S/W resources. Integrating CSCW applications in such heterogeneous environments is highly complex. This paper describes the design and implementation of ASS (application sharing server) which supprot sharing of a single application between different operating systems. The ASS supports cooperative work among user group using its own window system (X-windwo or MS-windwos). We adopted improved managing heavy-weight data. ASS also provides development environment for vaious groupware application.

Recently, it has been known that it need to be solved export marketing on expanding export of Small Business Commodity. Therefore, the purpose of this paper is to analyse on expanding export of Small Business Commodity through e-Trading Application in Industrie 4.0. This study deals with the terms of three connection success factors on expanding export of Small Business Commodity through e-Trading Application in Industrie 4.0 which are a firm's subjective factors, a industrial environment factors, and a governmental policy factors. According to analysis results of the three success factors, a firm's subjective factors(4.13 score) are scored at the most ones of the three success factors, to be compared with a industrial environment factors(3.89 score), with a government policy factors(3.72 score). Therefore, first of all, it is important to expanding export of Small Business Commodity through e-Trading Application in Industrie 4.0 through as follows, a firm's subjective factors : (1) to procure concentrated market strategy and real market capacity, (2) to procure speedy satisfaction of customer needs and confidence, (3) to procure ability of export marketing through e-Trading Application, (4) to enhance export expanding strategy coincided in Industrie 4.0. And, the next, we have to expanding export of Small Business Commodity through e-Trading Application in Industrie 4.0 through considering a industrial environment factors and a government policy factors.

The offline verification of state of charge estimation, power estimation, fault diagnosis and emergency control of battery management system (BMS) is one of the key technologies in the field of electric vehicle battery system. It is difficult to test and verify the battery management system software in the early stage, especially for algorithms such as system state estimation, emergency control and so on. This article carried out the virtual environment modeling for verification of battery management system. According to the input/output parameters of battery management system, virtual environment is determined to run the battery management system. With the integration of the developed BMS model and the external model, the virtual environment model has been established for battery management system in the vehicle's working environment. Through the virtual environment model, the effectiveness of software algorithm of BMS was verified, such as battery state parameters estimation, power estimation, fault diagnosis, charge and discharge management, etc.

본 논문에서는 동적으로 변하는 그리드 자원이 그리드 컴퓨팅 환경에 자동적으로 참여할 수 있는 미들웨어 시스템인 AGE(Automatic Grid Environments)를 소개하고자 한다. 기존의 시스템에서는 그리드 환경을 구축하기 위하여 각각의 그리드 노드들에 미리 필요한 미들웨어를 다운받아 환경을 설정하여야 하였지만, AGE는 노드가 그리드 환경에 참여하기 위하여 미들웨어를 자동적으로 설치하고 실행하는 기능을 제공한다. 또한 그리드 작업을 실행하기 위하여 필요한 응용프로그램을 사전에 설치하지 않고, 각 그리드 노드에서 실행될 때 다운로드받아 설치 및 실행되는 환경을 제공한다. 즉, 사용자는 그리드 환경의 구축에서부터 작업의 실행 및 구축된 그리드 환경을 제거하는 등의 모든 처리과정을 편리하게 이용할 수 있다.

This study focused on the analysis of residential satisfaction and environment awareness depending on the environment-friendly level on the outdoor space of the housing complexes. The purpose of this study is to present basic materials of the environment-friendly outdoor space planning of housing complexes. The major findings of the study are as follows. First, the results of the comparative analysis of the satisfaction of the outdoor space of apartment complexes show that the complexes with the most application of environment-friendly elements had higher residential satisfaction. But there was no meaningful statistical difference between the complexes with the higher level of application of the environment-friendly elements and the complexes with medium level of application. Secondly, according to a comparative analysis, the overall residential satisfaction of the apartment complexes was the same as the residential satisfaction of the outdoor space. Thirdly, the results of the correlative analysis of residential satisfaction and environmental awareness showed that the satisfaction of the apartment complexes decreases as the awareness of the environment-friendly apartment complex increases. The results of this study can be used as basic materials for environment-friendly outdoor space planning of apartment complexes.

The natural environment of the modern society does not simply reflect damage, but is a complex and grave reality that threatens the Earth. To solve this problem, various aspects related to the natural environment have been explored around the world, and a number of studies are ongoing to balance the development and preservation of the natural environment in Korea. However, no clear category exists for the natural environment and the related terms are ambiguous, rendering the overall evaluation system is in efficient. Therefore, the present study attempted to set the scope of application of a comprehensive evaluation system based on terms similar to the natural environment, concepts of the natural environment viewed from a value-based perspective and a capacitive perspective. In addition, by examining the concept of ecosystem services, a conceptual model for efficient application of the evaluation system of the natural environment through the association between categories of the natural environment is presented to derive implications for practical operation in the future.
