In this paper, we propose a method that measures quality of digital correlator. Quality of digital correlator in field of image composition of radio astronomy have as important position for acquisition of radio wave image with high precision. Digital correlator should have wide bandwidth and high precision to study on deep space. Digital correlator, therefore, should be designed to have high speed processing and high precision. But, real time measurement of quality of digital correlator using acquisition data is difficult to compare accuracy of result because digital correlator should process a large quantity of data with high speed. Measurement method of quality, also, has intricate implementation of experiment equipment. this paper present methods that compose experiment equipment without external installation easily and verify quality of digital correlator perfectly.

The quality of building space program is a key to measure how the building performance satisfies its owner and users. However assuring its efficiency requires reliable criteria that reflect high level experience knowledge in the field. This study suggests a plan to gauge the level of building space performance using expert knowledge, which has not been utilized well enough but should play a critical role. In order to setup an expert system measuring level of the space program, we firstly optimized the space areas to the best case in a knowledgebase and use them as criteria to judge the quality of the spaces extracted from BIM model. We found the experimental results show us a promising way of measuring a relative quality of the space programs.

Product characteristic approach and hedonic method were explained and applied to demand behavior of housing for 360 households sampled from four districts of Seoul. Th major findings are: 1) Housing prices are determined by housing characteristics, i.e., basic structure, interior space, interior quality, and neighborhood quality. 2) as income increase , the demand for basic structure, interior space, interior of quality, and neighbor hood quality increases. As compared to the counties that have advanced housing financial systems, income elasticity form housing characteristics was low. 3) householder's educational level has insignificant effects on the demand for neighborhood quality. 4) the housing need of family is different to a family life cycle. In the first stage, the increase of income enhances the demand for basic structure. interior space, and interior quality, but inversed with neighborhood quality. In the second and third stages, the demand for basic structure, interior space, and interior quality increases as the income increases. 5) It is predicted that the larger the family size, the more housing space is required. But in the low-income group, an increase in family size results in a decrease in the demand for interior space because expenses for food and education are indispensable ones. In the middle -income group the demand for interior space, interior quality increases as the family size increases, In the high-income group, the larger the family size the more interior quality is demanded. As mentioned above, the demand for housing is derived form characteristics and the demand behavior far housing characteristics is varied with individual household's characteristics. Therefore, the fact that different housing needs according to various income groups should be considered in housing policy.

Purpose: We research on the efficient response surface methodology(RSM) design to develop a design space in Quality by Design(QbD). We propose practical designs for the successful construction of the design space in QbD by allowing different number of replicates at the box points, star points, and the center point in the rotatable central composite design(CCD). Methods: The fraction of design space(FDS) plot is used to compare designs efficiency. The FDS plot shows the fraction of the design space over which the relative standard error of predicted mean response lies below a given value. We search for practical designs whose minimal half-width of the tolerance interval per a standard deviation is less than 4.5 at 0.8 fraction of the design space. Results: The practical designs for the number of factors between two and five are listed. One of the designs in the list could be chosen depending on the experimental budget restriction. Conclusion: The designs with box points replications are more efficient than those with the star points replication. The sequential method to establish a design space is illustrated with the simulated data based on the two examples in RSM.

Accessibility of urban green space, as an important index of evaluating the service level of urban green space, not only shows the resident's access to green space, but also reflects the environment quality of urban living. Since the quantity, area and space distribution of the patches in urban green space directly affect the function of urban green space and the quality of urban environment, the research on the accessibility of urban green space holds great significance to improve the service of urban green space and the living environment quality. Based on GIS software, this research uses the road network and the population distribution data of Nanjing's city proper to conduct quantitative analysis of the accessibility of park green space and the convenience for residents to travel under different forms of transportation. After the case analysis, the author tests the application of road network in studying the accessibility of urban park green space and proposes a GIS-based method to study the accessibility and the rational layout of urban green space.

This research tried to observe transition quality of unit plan for public space Korea public operated house since the 1950s. Plane of public-operated house had continually accommodated lifestyle change until present from the late 1950s. "Frontward 3 urface unit 3LDK'composition plans become settle by the representative plane after the 1990s. The process that with special quality change of public space the relation is deep. it is proposed consequently to analyze the space special quality change of the public operated house unit plan style.

본 연구를 통해 레스토랑의 식공간 매력성(attractiveness)이 고객들의 레스토랑 평가에 어떻게 영향을 미치게 되는지를 실험 연구 방법에 의해서 규명하고, 동시에 소비자 행동에 영향을 미치는 구매 위험 지각과 감성 강도가 레스토랑 평가에 대한 식공간 매력성의 효과를 어떻게 조절하는지를 확인하였다. 한편, 종속 변수를 레스토랑의 예상된 서비스 품질과 이용 의도로 설정하고 식공간 연출의 효과를 파악하고자 하였다. 연구결과를 요약하면 다음과 같다. 첫째, 매력적으로 연출된 식공간은 매력적이지 못한 식공간에 비해 레스토랑 고객들의 예상된 서비스 품질에 대한 긍정적인 평가를 유도하고, 또한 이용 의도를 증가시켰다. 둘째, 연출된 식공간의 매력성은 저(低)위험 지각의 구매 상황보다 고(高)위험 지각의 구매 상황에서 레스토랑 고객들의 예상된 서비스 품질과 이용 의도에 대해 보다 큰 영향을 미쳤다. 셋째, 연출된 식공간의 매력성은 감성 강도가 낮은 고객보다 높은 고객의 예상된 서비스 품질과 이용의도에 대해 보다 큰 영향을 주어 개인 특성 변수인 감성 강도의 조절 효과가 밝혀졌다.
