This study is performed to improve the elevation design of schools by the tools of color. Color is a very powerful design tool, one that is capable of altering the perception of a building or a space. The present form and material of elevations of schools are very monotonous and uniform. Therefore students do not have attachment for schools. And also in neighborhood, schools do not function as a good landmark. This study aims to develop good sample of exterior color design for schools and verify the guideline of color design for schools which was went ahead of this study. Through the survey of color preference and color image preference of the students of Seoul High School, the attitude of students to color were considered in design. The exterior color design for Seoul High School was realized. The result of this study suggests that the exterior color design can improve the image and plasticity of present schools. But within the monotonous character of present elevation, the effect of color design will be limited. Therefore to make a effective project, exterior color design should be accompanied with the alteration of elevation to make a plastic element of elevation.

With rapid economic development in Korea, interests in interior design have increased gradually. However, interior design markets were poorly evaluated from 2015 Korean Consumer Evaluation. It is necessary to identify what kinds of problems, defects, and consumer claims have arisen during interior design planning and construction procedures. Therefore the purpose of this study is to investigate claims and disputes in interior design project procedures and to find out when defects or claims take place in those procedures in order to reduce claims or defects. Email questionnaires were distributed to KOSID members (professional interior designers) using Google Survey. In addition, a focus group interview was conducted. A total of 54 responses were collected and analyzed using SPSS 19. As a result, in an agreement stage, alteration in materials is the major source of claim. More than a half of respondents addressed time shortage for programming and planning. During the construction stage, approximately 31% respondents experienced client dissatisfaction with materials and finishes. The reason for project completion delay was due to claims during construction. The claims most frequently appealed by clients were related to painting. The satisfaction with project quality is positively related to the quality and contents of design documents including design drawings and specifications. Regulations and communication with clients are important issues to reduce the gaps between interior designers and clients/ consumers.

The rapid growth of economy improves not only the life quality of people in this modern society but also standards of value in connection with how those people would spend money as they engage in various leisure and cultural activities. That being the case, hotels are currently changing into places of new concepts depending on those new lifestyles of these people, and in those new places, people can entertain and experience as enjoying cultures. The marketing collaboration of the hotels with brands can be used as a more inclusive way to enhance brand images. In addition, as having infinite possibilities of the collaboration's being able to create a new-concept space with an identity of a brand included, this collaboration makes it possible for the design hotels to decorate their interior spaces differently from those of other hotels. In the light of that, the brand collaboration is basically divided into three groups which are the fashion collaboration, the technique collaboration and the designer collaboration, and the brand collaboration is also able to express the interior spaces of the design hotels as working on those six components, such as reproduction, events, alteration, messages, culture and image. After all, through the brand collaboration marketing, this thesis expects an interior design of a new-concept design hotel which would play a role as a complex cultural space.

This study introduces a general reliability-based, performance-based design framework to design frames regarding their uncertainties and user-defined design goals. The Iterative-R method extracted from the main framework can designate a proper R (i.e., response modification factor) satisfying the design goal regarding target reliability index and pre-defined probability of collapse. The proposed methodology is based on FEMA P-695 and can be used for all systems that FEMA P-695 applies. To exemplify the method, multiple three-dimensional, four-story steel special moment-resisting frames are considered. Closed-form relationships are fitted between frames' responses and the modeling parameters. Those fits are used to construct limit state functions to apply reliability analysis methods for design safety assessment and the selection of proper R. The frameworks' unique feature is to consider arbitrarily defined probability density functions of frames' modeling parameters with an insignificant analysis burden. This characteristic enables the alteration in those parameters' distributions to meet the design goal. Furthermore, with sensitivity analysis, the most impactful parameters are identifiable for possible improvements to meet the design goal. In the studied examples, it is revealed that a proper R for frames with different levels of uncertainties could be significantly different from suggested values in design codes, alarming the importance of considering the stochastic behavior of elements' nonlinear behavior.

It is essential to construct on efficient material flow system for the successful introduction of automated manufacturing systems. Automated Guided Vehicle System(AGVS) ploys a significant role more and more in modern manufacturing environments, because of the flexibility and the precision they offer. However, as the size and the complexity of systems increase, the problems of dispatching, routing and scheduling of AGVs became complicated due to their independent and asynchronous demands. In this paper, we review relevant papers, and provide a new and more efficient method for partitioning the AGV system by introducing the concept of Central Path. This method named Central Path design has advantages, since each partitioned workstation group is served by one AGV and the material handling between groups is performed by special AGV that is used for the Central Path. Therefore the congestion problems never occur. Furthermore Central Path Design has a high flexibility for alteration and extension of system. Finally, we demonstrate its efficiency using simulation.

Process gases with vapor or liquid phase as well as gas phase may experience alteration in itself or be contaminated in the fluid pipe to the process chamber. And thus it result in as particles or defects on the substrates in semiconductor, LCD, LED manufacturing. Purifiers and filters are used for control of contamination. However, none of detection device is available in the delivery line. In this paper, we propose simple device with lighting and sensing in order to predict contamination of the fluid or the tube wall. For some general purpose gases, it showed constant voltage output regardless of the flow rates. But, the smoke and the moisture in the air lowered the figure due to its concentration. Numerical values for several solid and liquid media were obtained. And, the operating temperature tendency was investigated.

In 1923, El. Lissitzky designed ‘Proun Raum’ to realize his spatial experiment in paintings that are called 'Proun'. For this, Lissitzky taken Pome 'element' to construct his imaginary space that combine time with space. Especially, Quadrangle make an important role by the reason of its potential energy. In other words, alteration of its four corners turn Quadrangle to rectangle or square, etc, and describe some force, motion and location as itself. Analyzing 'Proun' and 'A and Pangeometry' that describes his spatial concept, spatial characteristics of 'Proun Raum' are comprehended, and the significance of spatial construction method in 'Proun Raum' are summarized as follows; occurrence of spectator's visual guide by elements, secession of afterimage, do-construction of the border.
