The environment is composed of at least two components, the natural and the human-made one. Nonetheless, the environment is being used to connote the natural environment. Moreover, even though the components of environment exist in a mutual relationship as a mechanism, it is rare to study the components of environment and their system as a mechanism. With such an implication, this paper aims to identify the components of environment and their system. The components of environment can be categorized by two criteria. One is the subject of creating environment, and the other is the visuality of environment. The former categorizes the environment into the natural and the human-made one, and the latter into physical and nonphysical one. Integrating the two criteria into a framework, the environment can be categorized into the natural, the human-made physical, and the human-made nonphysical environment. The three categories of environment exist interrelatedly in a mechanism being characterized as a mutual impact. The mechanism may be called the environmental system. The environmental system can be analyzed in terms of two dimensions. One is a human-inclusive system. The other is a human-centered system. The former is a framework that includes humans as a component of environment. The latter is a framework that humans are the subject of the environment, and the others surrounding human life are the object of the environment. The former is defined as a circular system of material and energy, while the latter is defined as a mutual subjective-objective system.

The purpose of this study is to clarify the actual condition of real certification schools of environment-friendly architecture per ecological environment elements through extracting ecological environment elements which is possible to analyze in quantity certification standards of environment friendly architecture. As the method of this study, firstly, certification as an examination on certification system of environment-friendly architecture, summary of certification system of environment-friendly architecture and eco-school pilot model project, ecological environment elements which is possible for quantitative analysis of ecological environment certification standards were extracted. Secondly, actual condition of ecological environment elements per school grade by collecting actual data of certification schools environment-friendly architecture were analyzed. As a result, total 35 environment-friendly school facilities are clarified that the average composition ratio of ecological area ratio is 23.0% in case of this certification regardless of school grade and region.

The PEM(Personal Environment Module) system is an individual air conditioning system developed in order to improve thermal comfort in office buildings. In this study, thermal characteristics of a PEM system have measured experimentally and compared with UFAC(Under Floor hir Conditioning) system in the EC(Environment Chamber) constructed in KIER. Results showed that the PEM system was better than UFAC system for thermal comfort and energy conservation.

MMOPRG는 게임의 장르적 특성상 플레이어가 게임월드(Game World)의 환경에 매우 큰 영향을 받는다. 따라서 게임월드에 구현되어진 물리적환경은 게이머에게 사실감과 몰입감을 주는 중요한 요소이다. 또한 구현된 물리적 환경이 게임 플레이에 영향을 주는 게임 시스템은 게임 플레이어에게 더 많은 사실감과 몰입감을 줄 수 있다. 본 연구에서는 현재 서비스되고 있는 MMORPG를 중심으로 어떠한 지구환경요소가 구현 되었고, 구현된 지구환경요소가 게임 플레이에 어떠한 영향을 주는 게임시스템이 구현되고 있는지 현황을 조사하였다. 지구환경을 시뮬레이션한 게임 시스템 즉, EESS(Simulative System of Earth Environment)를 디자인하기 위해서는 어떠한 문제점이 있는지 알아보았고, EESS를 좀더 쉬운 방법으로 접근하기 위해서 게임 월드에 구현된 환경의 대기상태, 풍향, 풍속, 일기현상 등의 상태정보를 처리하는 시스템인 '환경정보시스템(Environment Information System)' 개발을 보완기술로 모색하였다.

In Korean agriculture, an automatic environment control system for greenhouse is essential to save labor and to increase the quality of products. The existing environment monitoring systems have weighed on greenhouse growers and researchers because of their high cost and difficult applications. Many sensors are widely used for monitoring the greenhouse environment, but most of commercial sensors are expensive and not suitable for use in greenhouses. Thus , the development of an environment monitoring system for exclusive use in greenhouses is essential . The objective of this study was to develop modular environment monitoring systems, which are low-cost , reliable and easy -to -use. The results showed that the sensors for indoor and outdoor environments and nutrient solution had the ranges and accuracies appropriate for use in greenhouses. Also the modular environment systems developed showed a satisfactory performance in terms of stability and reliability in the measurement and acquisition of the greenhouse environment data.

The purpose of this study is to examine the actual condition of environment conscious logistics system which is essential to make material recycling economic society. Environment conscious logistics management which meant simply recycle is tend to promote material reduction, reuse and recycling. We have made case studies about advanced environment conscious logistics system. To examine korean companies' environment conscious logistics system, we made survey form which is consist of 81 questionnaires in Korea between 2003 and 2005. And we have analyzed the survey responses. As a result of this study, we propose the way of constructing environment conscious logistics system in Korea.

The temperature control system which is using liquid and gaseous nitrogen has been known as the most economical system to simulate space temperature condition due to relatively not expansive price of the liquid nitrogen (less than 0.2 USD per liter). And, among these systems, the closed loop system which circulates compressed nitrogen gas come from sprayed liquid nitrogen by blower and makes a target temperature with heat from an electrical heater and flow rate of liquid nitrogen is prevail all over the world. But, this complete closed loop system requires expansive equipments such as blower, heater, and liquid nitrogen injector, and special maintenance on the system. Therefore, KARI is developing efficient and simple open loop system which utilizes liquid and gaseous nitrogen with eliminating a special blower and other expansive units. In this study, this open loop system with more efficiency and flexibility will be designed and introduced.

This paper presents an embodiment of design integration framework corresponding to changes in the latest manufacturing environment. The embodied system is named by 'WEB-KBE System' because it supports a product design with a KBE technique based on web environment. The final purpose of the work is to implement a web-based integration design environment with a KBE technique to support non-skillful designers. The framework of the system Is designed to support necessary items in user-centric design environment. Two case studies were applied to the WEB-KBE system to evaluate the efficiency, flexibility, extensibility, and reusability of the system. The examples are [1] CART integration design environment construction and (2) Exhaust Duct Saddle Support integration design environment construction. In the former case, it took a period of 8 months for modeling and implementation of the WEB-KBE prototype system. However, with the high extensibility and reusability of WEB-KBE system, the second case required only a period of one month for modeling and implementation of the system. We conclude that the presented WEB-KBE system can bring fair effects on implementing a knowledge based design environment in aspect of time and expense.
