Improved efficiency in the use of natural resources, pragmatic production systems and environmental sustainability, justified by the need for improved land use systems and increased productivity, are discussed in the context of Asian integrated systems, diversification, and issues of sustainability. The importance of these are reflected by serious inadequate animal protein production throughout Asia, where available supplies cannot match current and projected human requirements up to 2050. Among the ruminant production systems, integrated tree crops-ruminant production systems are grossly underestimated and merit emphasis and expansion. As an example, integrated oil palm- based system is an important pathway for integration with ruminants (buffaloes, cattle, goats and sheep), and provides the entry point for development. The importance and benefits of integrated systems are discussed, involving animals with annual and perennial tree crops, integration with aquaculture, the significance of crop-animal interactions, stratification of the systems, production options, improved use of forages and legumes, potential for enhanced productivity, implications for improved livelihoods of the rural poor and the stability of farm households. The advances in research and development in South East Asia highlight demonstrable increased productivity from animals and meat offtakes, value addition to the oil palm crop, sustainable development, and distinct economic impacts. The results from 12 out of a total of 24 case studies concerning oil palm over the past three decades showed increased yield of 0.49-3.52 mt of fresh fruit bunches (FFB)/ha/yr; increased income by about 30%; savings in weeding costs by 47- 60% equivalent to 21-62 RM/ha/yr; and an internal rate of return of 19% based on actual field data. The results provide important socio-economic benefits for resource-poor small farmers. Potential increased offtakes and additional income exist with the integration of goats. Additionally, the potential for carbon sequestration with tree crops is an advantage. The reasons for low adoption of the syatems are poor awareness of the potential of integrated systems, resistance by the crop- oriented plantation sector, and inadequate technology application. Promoting wider expansion and adoption of the systems in the future is linked directly with coherent policy, institutional commitment, increased investments, private sector involvement, and a stimulus package of incentives.

소프트웨어의 통합환경을 구축하기 위해 통합 프로젝트 지원한경(IPSE: Integrated Project Support Environ-ment)을 구축할 때에는 2가지의 문제가 발생한다. 첫째는 도구의 밀도에 관한 문제이다. 여러 가능을 하나로 통합하는 조립 과정을 거친 도구들의 인터페이스에 관한 문제와 도구의 일 부 기능을 다른 도구와 함께 사용하는 경우 닫혀진 인터페이스로 인해 이용이 곤란해지는 경우가 발생할 수 있다는 점이다. 둘째는 프 로세스에 관한 자료를 수집할 때 발생할수 있는 문제이다. 개발 프로세스를 향상시키 기 위해 이를 측정하려고 할 때 도구를 사용하여 개발된 것이 아니기 때문에 측정이 곤란하다는 점이다. 본 연구에서는 이와 같은 문제를 해결하기 위해 도구를 정밀도화 하고 프로세스 정보를 취득하기 위한 기구를 추가할 필요성을 기술하고 문제해결을 위한 분석과 설계 방안을 모색하였다. 그리고 도구의 결합도와 응집도 및 통합적합성 에 대한 메트릭스를 제안하였다. 끝으로 본 연구결과에 기초하여 환경을 구축하는 경우에 일어날 수 있는 문제점에 대한 고찰과 평가를 하였다.

Nowadays major shipbuilding companies are trying to expand their business not only to shipbuilding but to offshore projects as well. DSME is one of them. DSME is trying to set up a flexible design and construction environment for shipbuilding and offshore construction in a single shipyard. The shipbuilding and offshore projects, however, have their unique technology but they need to be designed and constructed in one site. To support this new requirement, DSME has developed an integrated CAD system for ship and offshore projects. In this integrated design environment, the designers can design commercial ships and offshore projects in a flexible manner. Concurrent design is very important for ship and offshore design. As compared to the complexity of the product, the design period is quite short. In effect, the design system for the ship and offshore project has to support concurrent design. One essential point of concurrent design environment is a product model based design system. DSME has developed and implemented the 3D product model concurrent design environment based on Tribon M3. Tribon is a widely used CAD system in shipbuilding area that is developed by Tribon Solutions. DSME has both customized the Tribon system and developed in-house application systems to support its own design and production procedures. All the design objects are modeled in one common database to support concurrent design and accurate production. The major in-house development focused on the modeling automation and automatic drawing generation. During the drawing generation process many of the additional production information are also extracted from the 3D product model. In addition, several applications and functionalities have been developed to apply the shipbuilding based Tribon M3 system to offshore projects. The development of shape nesting, tubular connection, isometric drawing, grating nesting systems are the typical.

This paper describes a newly developed simulation environment for analysis and design of a plasma processing chamber based on first principles including complicated physical and chemical interactions of plasma, fluid dynamics of neutrals, and transport phenomena of particles. Capabilities of our simulator, named VIP-SEPCAD (Virtual Integrated Prototyping Simulation Environment for Plasma Chamber Analysis and Design), are demonstrated through a two dimensional simulation of an oxygen plasma chamber. VIP-SEPCAD can provide plasma properties such as spatiotemporal profiles of plasma density and potential, electron temperature, ion flux and energy, etc. By coupling neutral and particle transport models with a three moment plasma model, VIP-SEPCAD can also predict spatiotemporal profiles of chemically reactive species and particles exist in plasma.

Increasing use of embedded systems has made many improvements on hardware development for specific purpose. Hardware changes are more expensive and harder to implement rather than software changes. Developers need tools to do design and testing of new hardware. Many simulation tools have been made to mimic the hardware and allow developer to test programs on top of new hardware. Virtual Development Environment for Embedded Software (VDEES) is one of the alternatives available. It provides an open source based platform and an Integrated Development Environment (IDE) that can be used to build and testing newly made component, faster and at low-cost.

Under 'The Design Street' Project, one of the urban environment improvement projects of Seoul, the facilities on the street have been greatly varied in terms of design. In addition, the municipal authority has pushed each district to develop its own identity based on the integrated design of the city. This study was aimed to propose a design which could solve the current problem in street furniture in terms of environmental improvement through an analysis on current street conditions in "Y" District as a part of Seoul Design Street Project. It has attempted to propose 11 street furnitures based on the basic strategy of 'Soft City' which has been promoted by Seoul City in accordance with the Seoul Public Facility Guidelines as 1. Airy Design, 2. Integrated Design, 3. Collaborative Design and 4. Sustainable Design. Among them, for the total design in Seoul six facilities - kiosk, manhole, traffic signal controller, public phone, road sign and waste receptacle were proposed by Seoul City have been accepted. For local differentiation, on the contrary, five items - planter bench, bollard, lifter, bike rack and fence have been newly designed and proposed. Furthermore, it is essential to carry out systematic supervision and continuous management on the detail design and construction of current regional design development projects.

데이터 동기화를 위한 표준 프로토콜인 SyncML은 현재 주소록, 일정 관리와 같은 다양한 응용 서비스 타입에 대한 클라이언트 디바이스와 서버간 동기화를 지원한다. 비록 표준 프로토콜은 제정되었지만, SyncML 응용 서비스 개발자들은 자 응용 서비스의 구체적인 로직을 구현하기 위해서 많은 개발 시간과 노력을 들여야 한다. 본 연구에서는 SyncML 서버 개발자들이 응용 서비스를 신속 정확하게 구현할 수 있도록 SDE(Service Development Environment)라는 통합 개발 환경을 설계하고 구현하였다. SDE는 Sync Library와 SEG(Sync Engine Generator) 툴로 구성된다. 또한 본 연구 결과의 실용성을 입증하기 위해 SDE를 이용하여 SyncML 서버를 구현하였으며, 여러 가지 동기화 시험과 성능평가론 수행하였다. 본 연구가 SyncML 개발자들이 모바일 응용 서버를 개발하거나 응용 서비스를 추가하는데 보다 쉽고 효과적으로 완수하도록 지원할 것으로 기대된다.
