유니세프(UNICEF)의 아동친화도시 조성사업(Child Friendly Cities Initiative, CFCI)이 특정 지방자치단체의 특수정책에서 지방자치단체의 보편적 정책으로 전환되는 현 시점에서 도시의 대표적인 공공공간인 도시공원의 아동친화환경에 관한 전반적인 진단과 점검이 필요하다. 그러나 대부분의 공원 관련 아동친화환경 사업은 어린이에 집중되어 있고, 현재 공원의 아동친화성을 평가할 수 있는 기준도 구축되어 있지 않다. 이러한 문제의식을 바탕으로 본 연구는 18세 미만의 아동과 지역주민이 모두 이용하는 근린공원을 대상으로 연구자 현장조사, 이용자 설문조사, 청소년참여 워크숍의 방법을 통해 아동친화환경을 분석하였다. 본 논문에서 파악한 아동친화도시 근린공원의 문제점은 다음과 같다. 첫째, 불분명한 아동의 개념과 정의로 인해 정책의 집행과 그 수혜의 대상이 일관되게 실행되지 않고 있다. 둘째, 근린공원은 아동을 위한 공공공간으로 인지되거나 활용되지 못하고 있다. 셋째, 근린공원에서는 청소년에 대한 고려가 매우 부족하다. 넷째, 공원 내 시설뿐만 아니라, 접근성과 공원 주변의 아동친화성이 미흡하다. 이러한 측면을 고려하여 추후 공원 관련 정책 개발에 있어 청소년을 포함한 소외 연령층에 대한 고려를 구체화한다면 아동친화도시 공공공간의 아동친화성 향상과 아동의 보편적인 권리 향상에 이바지할 수 있을 것이다.

In Ubiquitous era. architecture is not the old building adapting ubiquitous technology. In order to take the role as new architectural paradigm in space, environment and technology, it has to develop technology continuously and experimental architecture at the same time. it must have co-evolution of architectural field and others through organic network. by that, the evolution of space will be in the way that combines space which is responded to human emotion and user-centric human-friendly. It will be the new paradigm of Ubiquitous digital space. Digital technology resulted in a change to a society as well as to the life of human and its way of thinking. Due to those changes, new terms or concepts come out and a new meaning is added to the conventional concepts. This aims to examine type of spatial contexts for interaction design experience. This study is performed through Literature research for theory by interactive space and case studies for construction elements to design. The range of case study is limited to interaction space in addition of interactive elements and user interface. And analysis conclusion is show the many type, First, Interactive space has special purpose for make a interaction by intelligent elements.(sensor, program, algorithm, New-technology) Second, Interactive space was cooperation with various professional for space purpose. Third. Interactive space is self-develop by algorithm, program, sensor network and that is harmonize with user. finally. Interaction space is show the temper elements about allness, metastatic, activeness, liquidity, relationship. That was written by ecological theory.

Recently, a direct data-driven synthesis of a proportional integral derivative(PID) controller for a linear time-invariant(LTI) plant was presented in [1]. The authors showed that a complete set of PID controllers achieving robust performance and stability can be calculated directly from frequency response(FR) data without an identified transfer function model. However, it is not convenient to use this method because it requires complicated numerical algorithms to find specific frequencies which are solutions of an identical equation. The method also requires determination of the boundary of the controller's parameters from a finite set of FR data. In this paper, we present the development of a user-friendly Matlab toolbox based on the method in [1]. This toolbox allows us to obtain a complete three-dimensional(3-D) graphical solution of PID controllers that meet multiple design objectives. Several examples are given to demonstrate the use of the toolbox.

Multidisciplinary Design Optimization (MDO) is an optimization technique considering simultaneously multiple disciplines such as dynamics, mechanics, structural analysis, thermal and fluid analysis and electromagnetic analysis. A software system enabling multidisciplinary design optimization is called MDO framework. An MDO framework provides an integrated and automated design environment that increases product quality and reliability, and decreases design cycle time and cost. The MDO framework also works as a common collaborative workspace for design experts on multiple disciplines. In this paper, we present the architecture for an MDO framework along with the requirement analysis for the framework. The requirement analysis has been performed through interviews of design experts in industry and thus we claim that it reflects the real needs in industry. The requirements include integrated design environment, friendly user interface, highly extensible open architecture, distributed design environment, application program interface, and efficient data management to handle massive design data. The resultant MDO framework is datasever-oriented and designed around a centralized data server for extensible and effective data exchange in a distributed design environment among multiple design tools and software.

A design for the front section of an excavator requires kinematic and kinetic mechanism consideration for several configurations. Key parameters for an appropriate configuration can be obtained through a mechanical verification and numerical formulation with a design expert's know-how. In this paper, we propose a knowledge-based system with an expert-shell(CATIA) and Visual Basic to assist for the design of the front section of an excavator. The designers can achieve more efficient design through a CAD model, implemented design knowledge, and a user friendly interface. The implemented design knowledge is retrieved through the whole design process from an early design stage to a detailed design stage based on the multiple levels of abstraction scheme.
