Purpose: The planning and design of hospital generally requires the participation and consultation of skilled experts since it has more complex space program than any other buildings. Therefore, the BIM systems for the planning of hospital have been tried continuously. The purpose of this study is to identify the precondition for space Program validation of healthcare architecture based on BIM, which is recently receiving wide attention. Method: For this study, United States, Australia and Finland's guidelines were analyzed among the description space program validation system in 14 overseas BIM Guidelines. And the propose precondition that can be applied to healthcare architecture from among these description of space program validation items, target, process etc for General building. Result: 1) spatial program validation is the following four evaluation phase. Step 1: Standard setting phase Step 2: BIM model accuracy assessment phase Step 3: space validation phase Step 4: Performance evaluation phase 2) The standards for the building elements at Standards Setting stage is considered to the standards for the architectural elements of General building. 3) Healthcare Architecture Area calculation method is considered to be reasonable that borrowing the area calculation standard of general architecture according to the UIA of international standards. However, Be proposed of measuring method that reflect the efficiency of the design process step-by-step area calculation method. The performance assessment indicators of reflect the Hospital uniqueness have to developed. And the research needs to be carried out continuously according to the purpose for healthcare architecture of feature-oriented. Implications: In this paper like to understanding that precondition of space program validation considering the BIM. As a result, understanding to condition about step of the evaluation, the evaluation standards. Is expected to keep the focus on the development of performance indicators that reflect the uniqueness of the hospital for the efficient evaluation of the Hospital building.

White-light scanning interferometry (WLI) and phase shifting interferometry (PSI) are increasingly used for surface topography measurements, particularly for areal measurements. In this paper, we compare surface profiling results obtained from above two optical methods with those obtained from stylus instruments. For moderately rough surfaces ($Ra{\approx}500\;nm$), roughness measurements obtained with WLI and the stylus method seem to provide close agreement on the same roughness samples. For surface roughness measurements in the 50 nm to 300 nm range of Ra, discrepancies between WLI and the stylus method are observed. In some cases the discrepancy is as large as 109% of the value obtained with the stylus method. By contrast, the PSI results are in good agreement with those of the stylus technique.

This study aims on finding a direction of desirable space organization of future elementary school in Korea by analyzing current status of space organization of elementary school in Japan. In this study comparison and analysis of curriculum of Korea and Japan, facility standards on national level and standards of national subsidy, current status of number of schools and students, transition of changes in facility area of elementary school for last 10 years are included. In Korea and Japan each 7 elementary schools which were constructed after 2007 and are good in space organization and school planning are selected. The comparison and analysis of satisfaction level on physical educational conditions and facilities such as current status of space organization and how to use them are conducted in this study. The contents of analyzing space organization are 'entry and placement, outdoor space', 'space program' and 'phase structure and organization of unit space'.

Purpose: The purpose of this study is to suggest a proper plan about the exterior space of elementary school in Korea through analyzing the various factors of the exterior spaces in foreign elementary school case. because the foreign cases have diversified eco-friendly certification standards on the elementary school unlike Korean cases. Method: First, we review the recent eco-friendly research trends of elementary schools and the external space characteristics of elementary schools that are currently being studied through related literary surveys, And we review the korean criteria factor for eco-friendly certification, we draw the types of exterior space thorough analysis framework, using the korean criteria factor. Second, the foreign cases of the elementary school were chosen, and then some planning data such as architecture scheme, design concepts and drawings will be collected. So the data were analysed and then the characteristics of physical setting and eco-friendly certification standards will be drawn. Third, We analyzed the characteristics and factor of physical and eco-friendly of exterior space through the drawn types. Result: The various physical settings are appeared physical environment. when we analyzed certification factors at korean eco-friendly standards, the suggestion and guide about the eco-friendly elements than the numerical goals were treated importantly in Korea.

In order to evaluate the performance of phone camera lenses, we have developed equipment for measuring the modulation transfer function(MTF) for small size lenses. The equipment is composed of an an image analyzer, object generator, and a lens mount. The object generator is rotated for on and off-axis measurement. The lens mount is of horizontal type and tiltable for precise alignment to the optical axis. After the initial alignment process, the measurement is done within 10 seconds automatically

The purpose of this study is to be suggested the primary data when housing research related the disabled and the enactment are needed. For the purpose, this study compares the Housing Laws, such as state of legislation, composition and detailed standards in domestic and international. The scope of study is limited each space in 7 types, entrance, corridor, living room, bedroom, bathroom, kitchen, and balcony, then, laws related on each space are compared and analyzed. In addition, comparison of the foreign's Housing laws are focused on Switzerland, Germany, United States of America, and Japan where have systematic and organized Housing laws by in each space. This study were processed as follows: First, domestic and foreign laws are examined throughout state of legislation, composition, detailed standards, and types of the disabled. Then, housing laws that applied institutionally in each country are compared. Finally, similarities and differences of specific standards are analyzed by comparison on space in each country.

Our previous study used a bar-type reference mirror to measure the relative distance to the target surface. The target measurement accuracy was required to $1{\mu}m$ PV for aspheric optical surface up to 1m in diameter. Earlier system suffers from the reference surface deformation when the measuring part moves. In order to reduce the deformation, measuring part and the reference part separated from each order in the new design. This system utilizes a kinematic support assembly using invar flexure to minimize the reference surface deformation under gravity and vibration. The surface deformation requirement of reference mirror is defined as of $0.2{\mu}m$ under gravity and 40Hz vibration. The finite element results, shows reference mirror deformation of $0.164{\mu}m$. The first resonance mode was computed to analysis 46.05Hz for reference part and 43.44Hz for measuring part. Thesis satisfies the frequency requirement.
