본 연구는 오늘날의 혼합현실 기술이 갑자기 등장한 것이 아니라 20세기 영상예술과 인터랙티브 아트에서 그 본격적인 단초를 찾아볼 수 있음을 탐구하고자 한다. 먼저 사진예술의 경우 평면에 입체를 표현하고 현실과 가상의 이미지를 혼합하여 혼합현실을 드러낸다. 포토그램은 2차원 평면이미지와 3차원 입체감을 동시에 느끼게 하였고, 포토몽타주는 다양한 사진을 결합하여 현실과 가상을 혼합하였다. 다음으로 영화에서는 오브제와 CG를 활용하여 가상과 현실을 결합하려 시도했다. 초기영화는 필름과 실물 오브제를 합성하였고, 컴퓨터 기술이 발전함에 따라 실사 이미지 위에 오브제 CG를 혼합하다가 배경 CG의 합성으로 나아갔다. 마지막으로 원격현전예술은 현실과 가상, 주체와 객체의 경계를 허물어 혼합현실의 새로운 가능성을 시도했다. 현실 속의 가상공간과 가상속의 현실공간을 오가거나 원거리 참여자의 원격제어로 혼합현실을 재현한다. 앞으로 혼합현실의 발전을 위해서 영상예술과 인터랙티브 아트의 참조는 더욱 필요할 것이다.

The first purpose of this paper is to study contact CR submanifolds of Sasakian manifolds and investigate some properties concernig with ${\phi}$-holomorphic bisectional curvature. The second purpose is to show an existence theorem of mixed foliate proper contact CR submanifolds in the standard Sasakian space form $E^{2m+1}$(-3) with constant ${\phi}$-sectional curvature -3.

We introduce two iterative algorithms for finding a common element of the set of fixed points of an asymptotically k-strict pseudo-contraction and the set of solutions of a mixed equilibrium problem in a Hilbert space. We obtain some weak and strong convergence theorems by using the proposed iterative algorithms. Our results extend and improve the corresponding results of Tada and Takahashi [16] and Kim and Xu [8, 9].

Low spatial resolution remote sensing (RS) data (LSRD) are promising in agricultural monitoring activities due to their high temporal resolution, but under such a spatial resolution, mixing in a pixel is a common problem. In this study, a numerical experiment was conducted to explore a mixed pixel problem in agriculture using a combined RSsimulation model SWAP (Soil-Water-Atmosphere -Plant) and a Genetic Algorithm (GA) approach. Results of the experiments showed that it is highly possible to address the mixed pixel problem with LSRD.

Under the dual pressure of population growth and land shortage, threedimensional development is the inevitable choice for cities in China. In such a scenario, a mixed-use complex has considerable potential in its realization and research. Based on space syntax and the three-dimensional visibility graph analysis, this paper describes the spatial and functional layout of the Shanghai Super Brand Mall and studies the relationship between spatial visibility and user behaviour through linear regression analysis and correlation analysis. This paper studies three different types of user behaviour, namely, path selection, staying selection, and store selection, and finds that spatial visibility and accessibility have different effects on user behaviour depending on the type and purpose of the activity. This paper reveals the influence of spatial and functional layout on user behaviour and puts forward the corresponding design strategy under the three-dimensional environment.

Mixed Use Area (Multifaceted Integration) is getting increasingly demanded since it has several merits such as preventing CBD from being emptied during night time, making daily life comfortable and utilizing the land more efficiently. However, the characteristic of Mixed Use Area -as advantages of it-, which is that it combines residence, retail, office, cultural, entertainment facilities altogether could be regarded as a weakness when it is viewed from each functions' original purposes such as residential and retail areas'. Accordingly, it is needed to do basic research and develop design guidelines of the Mixed Use Area to prepare its another take-off. The purpose of this research is to study theoretical background of Mixed Use Area's birth, understand its status quo by examining examples overseas and presented possible standardized ways of developing it.

To meet the demand of higher handling capacity, a mixed-flow submersible deep well pump was designed and tested. The main hydraulic components are made of plastics, which is free of erosion, light-weight, and environment-friendly. To simplify plastic molding process, and to improve productivity, an axial-radial guide vane was proposed. To clarify its effect on the performance, a radial guide vane and a space guide vane are developed as well. By comparison, the efficiency of the pump equipped with the axial-radial guide vane is higher than the radial guide vane and is lower than the space guide vane, and its high efficiency range is wide. The static pressure recovery of the axial guide vane is a bit lower than the space guide vane, but it is much larger than the radial guide vane. Taking the cost and molding complexity into consideration, the axial-radial guide vane is much economic, promoting its popularity for the moderate and high specific speed submersible deep well pumps.

The purpose of this research was to find out the preferences in HMUBs for living space in respondents' later life. For this purpose, this research was conducted by social survey research using a questionnaire for those who lived in an urban area around Seoul. The data was collected from November to December, 2005. The results of this research were as follows. Firstly, respondents agreed with living in high rise mixed use buildings in their later life because of convenience. Willingness to move into HMUBs was positive. Concerning preferred physical features, residents preferred living in either lower floors or higher floors because of safety or fine views. Regarding the usage of common space and facilities, they wanted to use them with other generations and preferred 2 bedroom type unit located in a suburban area. Secondly, the preference for living in a HMUB in later life was higher in women respondents than in men. Thirdly, the preference for living in a HMUB in later life was higher in upper floors than lower floors according to property and asset value. As a conclusion, the development of HMUB housing for older people has a bright prospect for urban residents in Korea.

The purpose of this study was testing the attitude differences on common space management between expecting residents and residents in high rise mixed-use residential buildings(MURB). Research method was social survey with questionnaire from 176 residents and 67 expecting residents by snow balling sampling. Research results were 1)residents want mostly 'convenience', but expecting residents want mostly 'amenity' from MURB environment 2)residents and expecting residents showed statistically significant attitude differences on willingly to pay, amount to pay and paying method about common spaces & facilities. 3)above two groups showed statistically significant difference on opening the common spaces & facilities to the community. 4)residents showed higher than expecting residents on impact degree of common spaces & facilities to neighborhood intimacy. 5)most of residents and expecting residents had an idea of 1-2 hour per week volunteer service at common spaces & facilities. Conclusively, survey on expecting residents's opinion might be needed to enhance the usability of common spaces and facilities in MURB. After the residents moving in, periodical evaluation about usability of each spaces & facilities needed to remodel common spaces.

The city means not only a geographical area as a role of the spatial boundary, but also a socio-economic place to communicate with each area. It requires various functions to get the income and economic-activities. But city has a limitation of a available land to provide the required functions and a sufficient space to supply the urban activity. Therefore, the development trend of city has not been to spread to the horizontal area any more and considered the vertical area. In addition, various functions put into a massive building because many people want to solve the daily requirements without spending time and cost in outer area. In this paper, it aimed at classifying the mixed-use building into function, circulation, relation according to the public and private space and the building shape to provide the design information such as land area, functional complex, accessibility, etc.. The classification of the mixed-use buildings is divided into four areas. The data are collected with foreign countries in Japan, Europe and US. Results of the study are as follows; First, the commercial function is mainly centered with other functions. Second, after studied the development scale, accessibility, building form, the commercial and residential area overwhelmly share at the total area.
