  • This research suggested the mathematical model (forward kinematics method) to provide the reference points of driver space more easily and accurately in designing the package layout of vehicle interiors. For this purpose, the lengths of body segments of drivers and various joint angles occurred while were used. The length data between joints for the mathematical model were extracted from $SAFEWORK^{\circed{R}}$ as well as 95th percentile male and 5th percentile female body dimensions were utilized. In addition, the angles of body segments were applied on its diverse values within proper ranges in order to compare them each other. the mathematical model in this study was based on the concept of converting polar coordinate system to Cartesian coordinate system so that reference points of driver space were acquired in Cartesian coordinate system after using the segment lengths of drivers and the joint angles of driving postures as an input of polar coordinate system. It is expected that reference points of driver space obtained from this research are helpful to the study on package layout that is appropriate for physical characteristics of drivers.

  • This paper has focused on comprehending the interior designs and characteristics of modern department stores in Korea by looking into the birth and changes of those built under the Japanese Forced Occupation Period. The first modem department stores including Mitsukoshi, Georgia and Hwashin Department Stores began to appear in Korea under the Japanese Colonial Rule. They considered a variety of architectural elements like construction planning, shop arrangement, path of customer movement and interior design. The interior of modem department stores aimed to pursue the so-called modernization movement, but failed to fully contain the unique characteristics of the times in that particular period. Modem department stores took on new western styles prevailed in Korea and were characterized by the eclecticism in which various architectural forms exist together. In other words, their interiors implied a sign of the times in the confusing and corrupt world then. Especially those modern department stores were designed, repaired and extended by foreign designers who were ignorant of the history of Korean architecture. What is worse, their further remodelling practices made big mistakes by considering only functional and economical aspects and giving a back seat to the architectural and historical value of existing modern department stores. Therefore, we should make more efforts to study and conserve the fundamentals of modem architectures like modem department stores in order to have better understanding of the aesthetic value of indoor space and facilitating smooth communication between past and present.

  • The purpose of this study is to draw out the features of expressions about Nature in Korean interior design, because the Nature has been being very important theme in the interior space. So, the 68 cases of domestic famous interior designers' works during last ten years were selected from authorized design magazines like as INTERIORS, MARU and so on. And next, the cases were analysed in according to interior image style, design elements used for effect of Nature and the direction of expression(directly or indirectly), As the results, composite expressions with a few elements were found in modern, hi-tech, elegant, minimal and casual styles, while direct expressions with many elements were found in natural and ethnic styles. And main elements for effect of Nature were trees and stones. Among many elements, water and stones became more important elements after 2000 than before. In the meantime the use of composite expressions was being increased and so appeared even in natural and ethnic styles.

  • Recently, the assisted living facilities for the elderly are increasing due to the facts, such as rapid increasing ratio of old people, rising incomes and the changing concepts towards family relationship. For the elderly, there is a need to re-examine how environment can incorporate design concepts which enhance accessibility and adaptability. For this survey each seven cases in Korean & American facilities were examined and also 120 copies of a questionnaire for the elderly who are above 60 were analysed. This survey revealed that; 1. The consciousness of the majority elderly was favorably aware of the assisted living facilities for the elderly by a social phenomenon. 2. At a response of the scale for the living unit, majority subjects preferred to live in size of 16${\sim}$20 pyung. 3. Subjects preferred not only clean and modern atmosphere, but also medical area and fitness room, design considerations for these points are needed. 4. Enough spaces for their hobbies and social activities, which are important factors for smooth understanding, communication and psychological remedy effect for the elderly should be provided in the facilities for the elderly. 5.Korean facilities were lack of accessibility, safety and adaptability, thus it is very important to select the suitable materials for the safety and lighting plans with regard to their physical and mental qualities.

  • Human factors engineering design guidelines for main control rooms(MCR) in nuclear power plants(NPP) have been applied to optimize human-machine interface(HMI) between operators and their equipment on the basis of physical, physiological and cognitive aspects. However, the HMI design for MCR is not found to be sufficient to maximize operators' performance since the operators in the MCR experience excessive stress due to the environmental factors such as inappropriate interiors and illumination. Therefore, well-designed environment of the MCR may be equally important to improve human performance in the MCR. The objectives of the study are two-fold: (1) to propose an interior design of SHIN-KORI 1 2 for pleasant and comfortable working environments, and (2) to design indirect lighting system to enhance visibility and productivity. The human factors engineering checklists were developed to examine whether or not the proposed human-environment design for SHIN-KORI 1 2 satisfies the regulations and guidelines presented by NUREG-0700 Revision 1. The implications of the human-environment design are discussed in detail.

  • This study included three experiments to evaluate in-vehicle exposures to PM10 and CO: 1) evaluation of in-passenger car exposures, 2) evaluation of in-public bus exposures, and 3) simultaneous evaluation of in-passenger car and in -university bus exposures. The tests of four factors (transportation mode, passenger-car type, commute period, and commute season were focused. A total of 40 actual passenger car commuters, 20 public bus commuters, and four university buses were recruited or surveyed. The same commuters ware participated in both the summer and winter studied. Two factory such as transportation mode and passenger-car type were found to have little effect on the in-vehicle levels of PM10 and CO. Commute period was found to have little effect on the in-vehicle CO levels. Conversely, the other factor, commuting season was found to influence on the in-vehicle levels of PM10 and CO. The present study also confirmed that under the Korean commute conditions, vehicle interiors are an important microenvironment for exposure to PM10 and CO. This was supported by finding that the in-vehicle Air levels were much higher than ambient air levels reported by several previous studies. The mean in -vehicle PM10 concentrations were 114 and 103$\mu\textrm{g}$/m$^3$for passenger cars and public buses, respectively. For CO, the mean in-vehicle concentrations were 2.9 and 2.6 ppm for passenger cars and public louses, respectively.

  • The purpose of this study is to analyze the relationship between the personality type and the residential evaluation & remodeling preference in interior finishes and floor layouts. The subjects of this investigation were collected through questionnaire from two hundred and twelve adult residents who live in Seoul, Korea. By using the rotated component matrix of varimax method & the one way anova method of spss for windows Rel. 11.0 in my former study, there are analyzed several significances in eight personality types; E(extraversion), I(introversion), S(sensing), N(intuition), T(thinking), F(feeling), J(judging) and P(perceiving) in MBTI (Myers Briggs Type Indicator). This study shows that actual floor plans, remodeling preference plans & interior finishes materials of each personality type was analyzed several significances by Chi-Square. As results, during consulting the client in the residential projects, personality test may take precedence over everything else, and then designer can consider it for hidden client needs in the residential interiors & remodelings. Designers might understand the nature of personality in order to design wisely for clients. This method will allow the designer & consultant to more fully understand clients' preference.

  • The phase changes, nitride precipitation and hardness variations of 14%Cr-6.7Ni-0.65Mo-0.26Nb-0.05V-0.03C super martensitic stainless steel were investigated after nitrogen permeation heat treatment at a temperature range between $1050^{\circ}C$ and $1150^{\circ}C$. The nitrogen-permeated surface layer was transformed into austenite. The rectangular type NbN, NbCrN precipitates and fine round type precipitate were coexisted in the surface austenite layer, while the interior region that was free from nitrogen permeation kept the martensitic phase. The hardness of surface austenite showed 280 Hv, while the interior region of martensite phase represented 340 Hv. When tempering the nitrogen-permeated steel at $450^{\circ}C$, a maximum hardness of 433 Hv was appeared, probably this is attributed to the secondary hardening effect of the precipitates. The nitrogen concentration decreased gradually with increasing depth below the surface after showing a maximum of 0.3% at the outmost surface. The strong affinity between nitrogen and Cr enabled the substitutional element Cr to move from interiors to the surface when nitrogen diffuse form surface to the interior. Corrosion resistance of nitrogen permeated steel was superior to that of solution-anneaed steel in the solution of 1N $H_2SO_4$.

  • The diffusion and partition coefficients of polyurethane foam (PUF) are estimated using a microbalance experiment and small chamber test. The microbalance is used to measure sorption/desorption kinetics and equilibrium data. When the diffusion condition is controlled in the chamber of the sample, interactions between volatile organic compounds (VOCs) and PUF can lead to the estimation of a relatively homogenous rate of mass transfer in the interiors and surfaces of PUF. The estimates of the material/air partition coefficient (K) and the material-phase diffusion coefficient (D) are shown to be independent of the concentrations of VOCs. This approach, if applied to a diffusion-controlled or physically-based model, can facilitate more precise prediction of their source/sink behavior. Although further research and more rigorous validation is needed, an emission model applied with the diffusion and partition coefficients from this research holds promise for the improvement of reliability in predicting the behavior of VOCs emitted from porous building materials by D and K.
