This is a study on methods for designers of furniture and products to generate and develop design concept in consideration of design and existing conditions of the space when they design street furniture. In particular, in case when they participate in a process of designing new space, this study aims to reveal methods generating strategic elements and basic ideas for designing street furniture through cases study of projects by understanding and analyzing concept of overall space design and by extracting artistic elements for deployment of specific designs. First, Design DNA, which decides overall flow of design concept of street furniture, is extracted through analyses of basic concepts of space design. Next, by applying 3V Design Process, alternatives of the concept generation are suggested through methods of storytelling and design language under the two approach methods of verbalization stage and visualization stage. Also its methods were explored through suggestion of designs by developing each idea of the respective concepts into specific design vocabulary.

Operational Concept Descriptions or Document(OCD) shall be developed to understand stakeholder's desire for to-be-delivered system. But there is little study on methodology of OCD generation and many developers do not understand importance of OCD in Korea. According to Nicole Roberts' industry(18 U.S. companies and organizations) survey, only 30% of system development projects had OCD, too. Researchers and developers have opposing views regarding the generation of an OCD. Many researchers believe that the development and use of operational concepts at the start of large projects is essential. Alternatively, developers may view the OCD as a burden to the development process rather than an enabler due to the extensive documentation requirement. In this paper a couple of OCD guidelines were investigated to clarify how to build a CONOPS effectively and what to include. Finally, OCD for rotorcraft based Personal Air Vehicle System(PAVS) was developed as a case study. In the future, a template for generating OCD appropriate to Korean environment could be proposed.

In Korea, we witness vivid evidences of changing trend in communication that insist the emergence of new networking architecture. To accommodate the changing trend and to hold current strong position in global IT industry, Korea have launched broadband convergence network (BcN) initiative. BcN vision for Korea is to be the first in the world to realize converged network infrastructure and ubiquitous service environment. In this paper, we have introduced the concept and the vision of BcN with a viewpoint of a new paradigm to prepare future-proof communication environment. And then, we have disclosed BcN research and development (R&D) activities including R&D philosophy, R&D phases, and key technologies required. Also, we have discussed current development issues in three technology branches including service and control technology, unified transport technology, and next-generation access technology.

Critical issues in the development targets for the future fast reactor(FR) cycle system, including sodium-cooled FR were to ensure safety assurance, efficient utilization of resources, reduction of environmental burden, assurance of nuclear non-proliferation, and economic competitiveness. A promising design concept of sodium-cooled fast reactor JSFR is proposed aiming at fully satisfaction of the development targets for the next generation nuclear energy system. A roadmap toward JSFR commercialization is described, to be followed up in a new framework of the Fast reactor Cycle Technology development(FaCT) Project launched in 2006.

A new waveform control technique has been developed for suppressing the spatter generation in the repelled transfer mode of high current $CO_2$ welding. Based on the spatters in repelled transfer, a waveform concept of concept was established in a way to drop the welding current to lower level right before the pendant weld drop detatchment so that the explosion force associating with drop detatchment was decreased. There were several variables to be controlled such as the moment of current drop, the base current and the time of retention at the base current. Either at lower base current or at longer retention time, the more instantaneous shot circuits were int개duced and thus the spatter generation rates were increased. With optimizing the control variables, the amount of spatter generated was decreased by about 30%.

본 연구는 제품 개발 단계에서 참여적 디자인 프로세스의 타당성을 검증하고, 이 과정에서 사용자의 적극적인 참여를 유도하기 위해 개발된 컨셉도출 툴킷과 참여적 디자인 워크숍의 효용성에 대해 재고해보는 데 목적이 있다. 이를 위해 유모차 디자인 사례를 선택하여, 컨셉도출 툴킷 (접착포 모형 유모차, 대여 코너를 위한 블록 배치 놀이)을 개발하고 세 차례의 워크샵을 통해서 디자인 개발을 하였다. 사례 연구를 통해서 참여적 디자인은 사용자의 적극적인 참여를 통해 사용 환경에 대한 보다 나은 이해를 제공하고, 디자이너의 선입견을 배제할 수 있도록 도와주며 디자인 팀의 간과할 수 있는 문제를 파악하게 해줄 수 있다는 점을 발견하였다. 또한 참여적 디자인 방법은 디자인 문제에 적합한 툴킷의 개발과 기획에 바탕을 두어야 한다는 점과 사용자들이 제시한 컨셉을 종합ㆍ분석해서 디자인에 적용하는 방법에 대한 필요성을 파악할 수 있었다.

In 1987, The Brundtland Report defined a sustainable development as the development that meets the needs of the present without compromising the ability of future generations to meet their own needs. This is the concept that we should cling to, to preserve natural resources of the present for the future generation. With this concept in mind, this paper criticized that the current waste management policy has been neglecting resource preservation aspect of waste management policy while giving too much emphasis on reducing waste generation. Thus, the purpose of this paper is to analyze how waste management policy can affect preservation of natural resources, and to investigate policy alternatives that can reduce both the volume of waste generated and the amount of natural resources that need to be consumed in the production process. The study was conducted based on the literature survey and system dynamics simulation. Borrowing Randers and Meadows's solid waste model with some modification of parameter and variables, this paper simulate several policy alternatives to figure out the most effective waste management policy set that can meet the need of the present without compromising the ability of the future generation to meet their own needs. Main concern was how to link waste management policy with resource management policy that can lead to minimization of waste generation and resource consumption.

지난 수년 동안 세대현상에 대한 관심이 증대하였다. 이와 같은 발전은 무엇보다 기존의 집단적 정체성의 형성에 영향을 미치는 요인들과 조건들이 변화하였기 때문이다. 그러나 세대에 대한 일반적 관심의 상승에도 불구하고 이에 대한 과학적 탐구는 일종의 저발전 상태에서 벗어나지 못하는 실정이다. 이는 무엇보다 개념 자체의 모호성과 다의성에 기인한다. 이 글의 목적은 세대개념에 내재된 다의성과 모호함을 개념의 사용맥락에 따라 분석적 구분을 통해 통제함으로써, 사회변동과 혁신을 파악할 수 있는 세대개념과 세대사회학의 위상을 재정립하는데 있다.
