The main scope of this study is to define such system of space composition factor to diversify the interior space of the apartment housing. Staring from the space analysis, identification of the design factors, characters of the anthropometry for the dwelling behavior, and analyzed dimensions of the interior furniture from the market data have uniformly integrated to engage with such system for innovation and diversification of the space design method. The elements of the composition factors are as follows: 1. Structural elements - $\circled1$Bearing wall $\circled2$Ceiling $\circled3$Floor $\circled4$Structural column 2. furniture elements - $\circled1$Fixed furniture $\circled2$Movable furniture $\circled3$Non-bearing wall $\circled4$F1exible wall $\circled5$Void & Solid 3. Finished material elements - $\circled1$Structural material $\circled2$Doub1e shell $\circled3$Color & Tone $\circled4$Lighting system For the design system selected space in restricted in 3way directional axis X,Y,Z to form its volume and direction of the space composition factors. X-axis is stands for horizontal length of the factor, Y-axis is for the space depth, and lastly, Z-axis is for the hieghts of the space based on anthropometris.

The purpose of this study is to derive system design factors and to analyze user needs of university library for design of user-centered information retrieval system. The result of this study can be summarized as follows: First, the concept of 'users-centered' in digital environment where the supporting role of intermediaries is growing bigger than before in the interaction with remote information retrieval system can be defined as the new concept of 'expansion of knowledge'. Second, 6 kinds of system design factors derived for user-centered information retrieval system design of the university libraries. Third, The user needs that examined and analyzed through the questionnaires made by user-centered approach according to the design factors should be considered for system design.

Although there has been substantial research on the squeal noise for the automotive brake system, robust design issues with respect to control factors equivalent to design variables in optimization, noise factors due to system uncertainties, and signal factors designed to accommodate a user-adjustable setting still need to be addressed. For the purpose, the robust design applied to the disk brake system has been investigated by DOE (Design of Experiments) based Taguchi analysis with dynamic characteristics. The specific goal of this methodology is to identify a design with linear signal-response relationship, and variability minimization. The finite element models of the disk brake assembly have been constructed, and the squeal noise problems have been solved by complex eigenvalue analysis. As the practical robust design to reduce the brake squeal noise, material properties of pad, disk, and backplate, thickness and geometry of pad are selected as control factors, material properties of pad and disk, and the contact stiffness have been considered as noise factors, and friction coefficient between pad and disk is chosen as a signal factor. Through the DOE based robust design, the signal-to-noise ratio and the sensitivity for each orthogonal array experiment have been analyzed. Also, it has been proved that the proposed robust design is effective and adequate to reduce the brake squeal noise.

Navigation system is regarded as the interface border line between the Intelligent Transportation Systems (ITS) and the driver as the prospective information provider of the ATIS (Advanced Traveler Information System). Following theory, if the navigation system appropriately designed and utilized, that can maximize the transport efficiency, contribute to improvements of the environments and road safety. To accomplish these dinds of objectives of the navigation system use, human factors plays an important roles specially focused on the driver's safety, performance and system usability. Because the effectiveness of the system depends on the acceptance of the system, and the extent to which the system conforms to driver physical and cognitive limitations and capabilities. Therefore, the ergonomic design vaniables must be seriously selected and reflected in early design step for more effective and appreciate product design. As the first step of this aim, this study selected and categorized the human factors design variables of the navigation system.

Human factors principles and evaluation methodologies are applied to design the MMIS of the KNGR. Human factors issues identified from the previous MMIS design of a nuclear power plant are considered in the development of the HFEPP. To manage human factors issues in the MMIS design of the KNGR, a conceptual Human Factors Issue Tracking System (HFITS) is also considered.

The Taguchi method was applied to investigate the effect of design factors on the performance of the shutdown cooling heat exchanger in the SMART-P. This method provided the simulation matrix for the KDESCENT program and an efficient tool for analyzing the simulation results. Levels of the design factors were selected by the effectiveness-NTU method. From 18 runs with the KDESCENT program, it was found that the performance of the system was greatly influenced by the inlet temperature at the shell side and the mass flow rate of the reactor coolant at the tube side. After applying the Taguchi method, we identified the important design factor that should be controlled and designed carefully. This method provides an efficient way to estimate the influence of each design factor on a system performance.

In this study, it was developed to the design program optimization the design factors of the carbon dioxide fire extinguishing system on the basis of design theory for the carbon dioxide fire extinguishing system, national emergency management agency (NEMA) notice No. 2012-11, KS B 6261 and steepest descent method of optimization. The design program was developed to C++ compiler based on established the logic and algorithms and was to operate on the Windows operating system. The optimization of design factors for the carbon dioxide fire extinguishing system are minimized subject to constraint on agent flow rate, emission time and design variables (pipe size etc.). It was verified to the design program performance for test system, and it was provided to the foundation for optimal design in fire fighting field. Also, it is considered to improve the efficiency of the fire extinguishing system and to maximize of fire suppression as the construction of the carbon dioxide extinguishing system based on the optimal design factors.

The purpose of this study is to examine the effect of value systems and social self-concept on the appearance management behavior and clothing benefits according to gender. The data were collected via a self-administered questionnaire from 453 male and female college students in Jecheon and analyzed by factor analysis, correlation analysis, multiple regression, and t-test. The results of this study were as follows: 1. Value systems and clothing benefits classified into four factors respectively. 2. There existed significant differences according to gender in value system factors, social self-concept, appearance management behaviors and clothing benefit factors. 3. There existed correlations between value system factors and social self-concept. For male students, four factors of value system were correlated with social self-concept. But only one factor(pursuit of peaceful and secure life) was correlated with social self-concept for female students. 4. In male and female students, appearance management behaviors and clothing benefits were influenced by various value system factors and social self-concept.
