David Gavid [3] proved that in many familiar cases the upper semi-finite topology on the set of closed subsets of a space is the largest topology making the coincidence function continuous, when the collection of functions is given the graph topology. Considering G-spaces and taking the coincidence set to consist of points where orbits coincidence, we obtain G-version of many of his results.

Contemporary space design has based on the framework of academic standards on a number of scientific propositions in order to find out correlation of human and environment and closely examine approaches of a normative design. However the contents are enormous and introductory and have limitation of application to practical business affairs so that we will have to understand them as a thinking to explain the design with,. Therefore this study is an experimental research making use of concrete design approaches applicable to the area of space design ad cinematic construction as a medium. The purpose and significance of it lies in examining its validity and contributing to the future development of space design. Accordingly this study conducted the research through a literature survey for the understanding of space perception in the cinema deduced the language of design concept according to it examined the basic unit of cinematic construction then analyzed the cases of practical architectural spaces. The findings of this study indicate that human's perception to space and the cinema is deduced as a common conceptual language characterized by the ideas of articulation scenery and timeness. These concepts are very organic and interdependent and can probably become a means for human to appropriately analyze an behavior attribute type of investigating environment with. Also in composing space the basic units of cinematic construction can be as instrument to be easily applied to practical affairs as they are correlated with the function of space and a constituent language to be reasonably designed.

The purpose of the study for this thesis is to look into the status and issues of government office buildings since the self-government policy through comparing and analyzing government office buildings, between domestically and to provide improvement plans of the citizen cultural space and with the self-government budget, enhance the utility and efficiency of the government office buildings and to take a role of a reference in the future when citizen cultural space is formed in the government office buildings. As the result of the study, the space planning characteristics of government office building's citizen cultural space in terms of cultural administration is as follows. First, percentage of room to strengthen the sense of community is small. Therefore, the place where residents can argue there is a need. Second, it is necessary to expand the venue and art collection that are missing in public government buildings. Third, since the lecture room for lack of civic education, it should be taken into account when making cultural space for the citizens. Fourth, thread observatory and souvenir shops, providing information is not enough, it is to be further expanded. Fifth, rented facility for public is hall be provided with a diversity.

This study examines for the making a deduction of architectural characteristics of high-rise business hotel's lower public space through analyzing the lobby space composition through Beijjng's 21 cases constructed from 1978 until 2008 in China. In the methods of analyzing process, We study the literatures, research reports and architectural drawings including the site survey. We hope to establish the principle in public space composition of Beijing's business hotels through analyzing the plan of these hotels. Finally, We find out the principles after researching as follows. Firstly, duration of business hotel construction was concentrated with the center of Beijing City especially central 5 Gu which will roll. To 1990's after that the high-rise hotel construction increased in order for the demand of the resort and the convention hotel to come to be many. The modem style was increased in hotel design of building's style. Secondly, the result which analyzes an 21 case study shows concourse style of public space composition is representative in lobby space of general 5 star business hotel in Beijing. And there are many upper composition style in sectional plan, modern style in lobby interior design. The third, the medium and small sized hotel have the plane which apply the public space efficiently.

Semi-supervised multi-view latent space learning is gaining considerable popularity recently in many machine learning applications due to the high cost and difficulty to obtain the large amount of label information of data. Although some semi-supervised multi-view latent space learning methods have been presented, there is still much space for improvement: 1) How to learn latent discriminant intact feature representations by employing data of multiple views; 2) How to exploit the manifold structure of both labeled and unlabeled point in the learned latent intact space effectively. To address the above issues, we propose an approach called semi-supervised multi-view manifold discriminant intact space learning ($SM^2DIS$) for image classification in this paper. $SM^2DIS$ aims to seek a manifold discriminant intact space for data of different views by making use of both the discriminant information of labeled data and the manifold structure of both labeled and unlabeled data. Experimental results on MNIST, COIL-20, Multi-PIE, and Caltech-101 databases demonstrate the effectiveness and robustness of our proposed approach.

The Korean Solar Radio Burst Locator (KSRBL) is a solar radio spectrograph observing the broad frequency range from 0.245 to 18 GHz with the capability of locating wideband gyrosynchrotron bursts. Due to the characteristics of a spiral feed, the beam center varies in a spiral pattern with frequency, making a modulation pattern over the wideband spectrum. After a calibration process, we obtained dynamic spectra consistent with the Nobeyama Radio Polarimeter (NoRP). We compared and analyzed the locations of bursts observed by KSRBL with results from the Nobeyama Radioheliograph (NoRH) and Atmospheric Imaging Assembly (AIA). As a result, we found that the KSRBL provides the ability to locate flaring sources on the Sun within around 2'.

In domestic construction industry, now demand for airport facilities, gymnastic facilities, mass meeting facilities, sales facilities is increasing. Because of this, demand for huge space is also increasing. In making huge space, existing PEB(Pre-Engineered Building) and Pipe Truss, As span is lager and larger, steel weight is increasing and hard to apply for large span. For solving this problem, Many program was proposed, and in that Space Frame was rising. But in domestic construction there are very rare practical use for Space Frame. In this study, we wish to introduce Space Frame that has several advantages in construction expense, construction time, constructibility and also with analyzing example for applying Space Frame, wish to investigate characteristic of Space Frame. Go forward better, through comparison of other different old method and basic character of Space Frame, confirm advantage of Space Frame that have infinite development possibility and revitalize the Space Frame in domestic study and further more wish to raise practical use for Space Frame.

Management decision-making based on artificial intelligence(AI) plays an important role in helping decision-makers. Business decision-making centered on AI is evaluated as a driving force for corporate growth. AI-based on accurate analysis techniques could support decision-makers in making high-quality decisions. This study proposes an effective decision-making method with the application of multi-label feature selection. In this regard, We present a CFS-BR (Correlation-based Feature Selection based on Binary Relevance approach) that reduces data sets in high-dimensional space. As a result of analyzing sample data and empirical data, CFS-BR can support efficient decision-making by selecting the best combination of meaningful attributes based on the Best-First algorithm. In addition, compared to the previous multi-label feature selection method, CFS-BR is useful for increasing the effectiveness of decision-making, as its accuracy is higher.
