본 연구는 애니메이션 스튜디오 비욘드 프로시니움이 제작, 발표한 단편애니메이션 에서 사용된 공간 디자인을 연구의 대상으로 하고 있다. 애니메이션을 위한 공간 디자인은 작품 속에서 연기자(캐릭터)가 연기를 통해 작품의 이야기를 전달하기 위한 장(Playground)이라는 기본적인 기능이 있고 나아가 작품의 시간적, 공간적 배경을 설명하거나 작품속의 은유나 상징체계를 시각적으로 표현해주는 장치적인 기능이 있다. 이 같은 기능을 충족시키는 디자인 결과를 얻기 위해 본론에서는 개념적 측면으로 시나리오의 은유와 상징적 의미체계를 공간 디자인에 적용하는 경우를 분석하였다. 제작적인 측면으로는 캐릭터와 소품, 카메라를 통해 잡힌 화면 구성과 이 같은 요소들의 움직임에 따른 동선을 복합적으로 고려하는 방법에 대하여 살펴보았다. 애니메이션제작을 위한 공간디자이너는 깊이 있고 복합적인 사고를 할 수 있어야 하며 이를 실질적으로 구현 할 수 있는 기술적인 소양이 필요하다.

This paper proposes an effective method on the DFILS(Design for Integrated Logistics Support) in ammunition development applying QFD(Quality Function Deployment) method. The goal of this research is to define the Design for ILS approach at the start of the ammunition development and to yield a set of reusable requirements. Based on 000mm High-Explosive(Warship ammunition) development work, a QFD software tool, CUPID, was used to analyze and define the field force's requirements. Additionally, a set of reusable requirements are identified and defined for use during the Design for ILS development phase in the next-generation ammunition development process. These set of requirements that consider both the priority and importance of the VOC(Voice of Customer) will contribute to the early phase of the ammunition development to implement the Design for ILS specialty engineering effort.

The diffusion of fuzzy logic techniques into real applications requires specific software supports which save development time and reduce the programming effort. But we has been lack of a tool devoted to support the design of fuzzy controllers. In this paper, on the basis of the general fuzzy set and .alpha.-cut set decomposition of fuzzy sets, a set of fuzzy reasoning tool(FRT) devoted to support the design of fuzzy dontroller for servo systems is developed. The major features of this tool are: 1) It supports users to analyze fuzzy ingerence status based on input deta and expected results by three-D graphic display. 2) It supports users to prepare input data and expected result. 3) It supports users to tuned scaling factor of membership functions, rules and fuzzy inference. The paper shows how the suggested design tools are suitable to give a consistent answer to the tuning of fuzzy control system. This FRT is expected to exert good performance and devoted to support which the design of fuzzy controller is illustrated in the servo systems.

Weight reduction for automobile components has been sought to achieve fuel efficiency and energy conservation. There are two approaches in reducing their weights. One is by using material lighter than steel, and the other is by redesigning their structures. The latter has been performed by adopting hydroforming, tailor weled blank, optimization, etc. In this research, the kriging approximation method and simulated annealing algorithm are applied to the design of a front door made by TWB (Tailor Welded Blank) technology. The design variables are set up as the thicknesses of parts and the positions of parting lines. A thickness set considered as a design variable of each part is not arbitrarily determined but selected from standard products, so it is a discrete set. This research presents the discrete and continuous structural optimization method for an automotive door design.

An efficient and robust algorithm to compute the exact Voronoi diagram of a circle set is presented. The circles are located in a two dimensional Euclidean space, the radii of the circles are non-negative and not necessarily equal, and the circles are allowed to intersect each other. The idea of the algorithm is to use the topology of the point set Voronoi diagram as a seed so that the correct topology of the circle set Voronoi diagram can be obtained through a number of edge flipping operations. Then, the geometries of the Voronoi edges of the circle set Voronoi diagram are computed. In particular, this paper discusses the topological aspect of the algorithm, and the following paper discusses the geometrical aspect. The main advantages of the proposed algorithm are in its robustness, speed, and the simplicity in its concept as well as implementation. Since the algorithm is based on the result of the point set Voronoi diagram and the flipping operation is the only topological operation, the algorithm is always as stable as the Voronoi diagram construction algorithm of a point set.

Diesel generator sets with resilient mounts often experience resonances by major excitations which come from diesel engine and their foundation with rigid body modes. Because their natural frequency is determined by moment of inertia and stiffness of resilient mount vibration problems are resolved by changing location and stiffness of resilient mounts. But the calculated natural frequencies are inaccurate due to uncertainty of the inertia and mount stiffness. So this result can be useless on the design stage. In this paper, the stiffness of mount is evaluated on result from mount stiffness test in laboratory and generator set vibration test and a simple calculation method for moment of inertia is proposed. Based on these data, the procedure to select optimized mount stiffness and location on the design stage is set up.

A structural modification of baseframe is an effective method to avoid resonance in marine diesel generator (D/G) set which consists of diesel engine, generator and baseframe. However the reinforcement with thick plates or additional parts to increase the natural frequency can be less effective because of increased weight. Especially fine control of target mode based on the experience is difficult because the weight and interference of system have to be considered. In this paper, the design optimization of baseframe was performed to reduce the resonant vibration using a gradient descent method. The design parameters such as thickness, shape and location of baseframe parts are optimized to increase the torsional natural frequency of D/G set. From the actual test, the new designed baseframe reduced the vibration level in resonance by 55% without any increase of weight and interference. interference.

Architectural design work depends on information made from earlier phases such as feasibility study, planning, and conceptual design. This design guideline information includes design objectives, requirements, and constraints made by decision-making, and has great influence on various works of latter phases of design process. Despite of this cognition, however, the lack of design guideline information management still remains as one among the critical issues in design area. Design tools with design guideline information do not also address the issue of interoperability throughout the life-cycle of buildings. The purpose of this research is to propose a method for design guideline information management by using the IFC technology and IFC Property set (Pset) extension mechanism. The method comprises defining and mapping the practically used design guideline items and extensible IFC data model, and includes the management of relationships that exist between design guideline information and design model in the IFC data model.

린은 고객이 정하는 가치를 정의하고 가치의 흐름에 방해되는 불필요하고 낭비되는 요소를 없애는 과정을 기본으로 하는 경영철학이다. 생산관리에서 출발한 린이라는 경영철학은 건설 산업에서“린 건설”이라는 이름으로 건설단계에서 시작되었으며 이제는 생산성 향상을 효과적으로 이룰 수 있는 설계단계로의 확장이 필요한 시점이다. 현재 국내의 구조설계업무방식은 순차적 공학 개념의 Point-based Design 방식으로 설계자의 경험과 판단에 의존하여 초기 설계안을 결정하고 이후 상세설계를 진행하는 과정으로 설계업무가 진행되었다. 이에 반해 동시공학 개념의 Set-based Design 방식은 전체 프로젝트 관점에서 낭비요소를 없애고 프로젝트 생산성 향상을 위해 다양한 설계안을 제한된 범위 내에서 바로 선택하지 않고 더 확실한 정보가 나올 때까지 설계안의 선택을 유보하여 합리적이고 경제적인 설계안을 결정하는 린 기반의 설계 프로세스이다. 본 연구에서는 전통적인 구조설계방식에 대해 SBD방식을 도입하고, SBD프로세스의 의사결정기법으로 계층화분석법(AHP)을 적용하여, 후행업무단계들에 대한 사전 고려로 프로젝트 전체 관점에서의 낭비를 최소화하고 생산성을 향상할 수 있는 설계 방법론을 제안하고 하고자 한다. 이를 위해 PBD와 SBD방식에 대한 분석 및 의사결정방안을 모색하였고, 제안된 SBD프로세스의 사례연구를 통해 실무에서의 활용방안을 제시하였다.

Let X be a finite set of elements that we shall call points. Let I be a set called an indexing set. A mapping $B : I \longrightarrow P(X)$ is called a family of blocks on X. For each $i \in I, B(i)$ is also written as $B_i$. We always assume $$\mid$B_i$\mid$ \geq 2$ for each $i \in I$.
