디자인 요소에서 레이아웃은 전체 정보 구조를 결정하는 중요한 요소로서 정보의 배치, 연결, 구분을 비롯해 사용자의 행동유도 및 정보 인지 등의 구조적 기능을 포함하고 있다. 최근 웹 인터페이스 디자인의 레이아웃은 전통적 Z레이아웃 개념에서 점차 F레이아웃으로 변화되다가 최근에는 Z레이아웃의 변형인 분할레이아웃 형태로 점차 변화되어가고 있다. 그러나 이런 변화 이유에 대한 객관적 근거가 부족하다고 할 수 있다. 따라서 F레이아웃과 Z레이아웃 사이에서 기능적 차이가 사용자 경험에 어떠한 영향을 미치는지에 대한 연구가 필요하다고 할 수 있다. 본 연구에서는 웹사이트의 제품설명 웹페이지를 중심으로 F레이아웃과 Z레이아웃 웹사이트에 대한 사용자 테스트를 진행하여 유형별 레이아웃이 사용자 경험에 미치는 영향을 조사하였다. 실험 결과 F레이아웃보다 Z레이아웃을 기반으로 한 분할 레이아웃에서 사용자가 느끼는 호감도가 큰 것으로 나타났다. 또한 효율성, 접근성, 몰입성 등 Z레이아웃에서 사용자의 호의적인 태도를 형성하는데 더 유리한 것으로 나타났다. 본 연구의 결과는 Z레이아웃을 기반으로 한 분할레이아웃으로 변화되어가는 웹디자인 추세와 일치하는 것으로서 사용자 평가를 통해 효과적인 웹디자인 레이아웃의 객관적인 근거를 제시하였다.

A computer-assisted desktop is developed for layout design of a concrete gravity dam on the basis of safety and economy. Using a set of regression equations, a dam layout is proposed. With reference to the regression equations and relevant input data, overall dam dimensions are determined by satisfying the stability criteria jointly under usual, unusual, and extreme loading conditions with the desired hydraulic conformity. Among several feasible alternatives, the program enables a designer to select the optimum layout, which corresponds to the minimum total cost of the structure. The method is applied to a case study to examine dimensions of proposed alternatives and to compare them with those of an existing dam.

There are many challenges in manufacturing system for new factory construction. Although factories produce same product, the layout of each factory may be different. The body shop in an automotive factory is a typical flow line with assembly, but the layout concept of the line varies among factories. In this paper, two types of layouts in the body shops of automotive factories, one for layered build and the other for modular build, are compared using simulation study. The simulation experiments indicate that the modular build layout is better than the layered build layout with respect to production rate. The effects of various failure distributions on the throughputs are also investigated, and some insights are suggested regarding the layout concept.

CAM은 RAM이나 PLA 처럼 규칙적인 구조를 갖고 있으므로 CAM 자동설계 프로그램을 제작하기 용이하다. 본 프로그램은 CIF 형태로 그 결과가 출력되고 수정 작업이나 결과를 화면에 보기 위해 IBM/PC 상에서 디스플레이 프로그램을 개발하였다. CIF 파저는 YACC와 LEX로 제작하였고, 플롯팅을 위해서는 ROLAND XY 플롯터를 사용하였다. 위의 과정을 하나의 메뉴안에서 선택에 따라 수행하도록 Full-Down 메뉴를 사용하여 종합하였다.

In this study we conduct the optimal spot-weld layout design of vehicle body structure considering dynamic stiffness and side impact. We conduct both linear static analysis and nonlinear analysis with a baseline model to verify the process. 13 design variables will be selected for the effect analysis. Then, topology optimization is conducted to each selected design variable. The design constraints are formulated to improve the dynamic stiffness and side impact performance. Objective function is to set the density of weld component. Optimal spot-weld layout design are compared with the baseline model to show the improvement.

본 연구에서는 그라운드 구조법을 이용하여 콘크리트 구조형태의 최적화에 대한 수치 실험을 하였다. 마이크로 격자 모델은 단위 셀의 집합체로 구성되었다. 해석 과정은 각 부재의 응답계를 강성에 피드백 시켜서 유한요소해석을 반복하였다. 이 해석의 반복을 통하여, 트러스 모델은 수리적 최적화 수법이 아니라 국소적인 응력 상태를 이용하여 위상적인 구조 형태와 구조적 형상을 표현하였다. 격자 트러스 모델을 여러 예제에 적용하여 형상 배치 문제를 해석하는데 성공하였다.

This study is aimed to look into the craftsmanship non-educated constructors in Korean-style secondary stations(Gong-So) of Naepo region which is located in the northwestern Chungcheongnam-do. Although the area was persecuted as one of three cradles of Korean Catholicism, Catholic activities flourished there. The 13 cases of Korean-style secondary stations were selected through a survey report list about modern cultural assets of Chungcheongnam-do published in december 2004. This study examined the methods of plan layout and framework of Gong-So to look into craftsmanship of non-educated constructors, the results are as follows; The methods of plan layout are divided into three types according to existence and arrangement of inner column(Nae-Ju); 'Layout with Nae-Ju' is considered as the primary form of Korean-style Gong-So with using regular Nae-Ju. 'Layout with the different position of the center between Nae-Ju and exterior column(Oe-Ju)' and 'layout without Nae-Ju' is appeared in Korean-style Gong-So which is important to assembly and alter function. The methods of framework are appeared variously according to different plan layout for securing worship space. The unusal beam(Chung-Ryang) is used to solve different spans of altar and narthex. When space was formed widely without Nae-Ju, diagonal members and M letter type rafters are used, they are influenced by the technique of western wooden roof truss.

This paper presents a method for designing layout on the yard and evaluating alternative designs of the layout by applying simulation. The method is based on the concepts of the conventional port container terminal with a perpendicular yard layout. In general, yard design of the container terminal is consists of the two major parts. One is to divide yard area between the number of sections and the number of runs and the other is to decide the number of equipment that is the yard truck and yard crane. In the past days, this design was depended on the experience of the terminal operator and the structure of the conventional terminal layout because it is a very complex decision problem. In this paper we suggest the method of yard design as a conceptual procedure and estimate the efficiency of the container crane and the optimal the number of equipment using the simulation. Numerical examples are provided in order to illustrate the conceptual procedure. As the example, the suggested method and simulation are applied to the virtual container terminal with a perpendicular yard layout. In the results, the number of sections and runs on yard area, the number of yard truck per container crane and the number of yard crane per run are decided. In additional, the traffic among blocks on yard layout is estimated in terms of rate.

Self Organizing Map (SOM) is a neural network that is effective in classifying patterns that form the feature map by extracting characteristics of the input data. In this study, we propose an algorithm to determine the cell formation and the machine layout within the cell for the cell formation problem with operation sequence using the SOM. In the proposed algorithm, the output layer of the SOM is a one-dimensional structure, and the SOM is applied to the parts and the machine in two steps. The initial cell is formed when the formed clusters is grouped largely by the utilization of the machine within the cell. At this stage, machine cell are formed. The next step is to create a flow matrix of the all machine that calculates the frequency of consecutive forward movement for the machine. The machine layout order in each machine cell is determined based on this flow matrix so that the machine operation sequence is most reflected. The final step is to optimize the overall machine and parts to increase machine layout efficiency. As a result, the final cell is formed and the machine layout within the cell is determined. The proposed algorithm was tested on well-known cell formation problems with operation sequence shown in previous papers. The proposed algorithm has better performance than the other algorithms.

The objective of optimization is to present a design process that minimizes the total material consumption while satisfying current codes and specifications. In the research an optimization formulation for RC shear wall structures is proposed. And based on conceptual design methodology, an optimization process is investigated. Then optimal design techniques and specific explanations are introduced for residential buildings with shear wall structure, especially for that with a rectangular layout. An example of 30-story building is presented to illustrate the effectiveness of the proposed optimal design process. Furthermore, the influence of aspect ratio on the concrete consumption and the steel consumption of the superstructure are analyzed for this typical RC shear wall structure; and their relations are obtained by regressive analysis. Finally, the optimal material consumption is suggested for the residential building with RC shear wall structure and with rectangular layout. The relation and the data suggested can be used for guiding the design of similar RC shear wall structures.
