Because of the rapid industrialization and urbanization, urban dwellers are lack of opportunity to contact with nature, and hence alienated from it. In particular, primary school children who are very sensible to nature need more opportunities to learn nature by direct interactions with it. For this purpose, a movement for making and using ecological learning-place in play-ground within primary school. It has been found as a result of research on ecological learning-places in 7 primary schools in Daegu that such places, equipped with several ecological facilities, provide both pupils and local dwellers around schools with a place for ecological learning and for rest. But some of them have been left without care and hence can not be properly used, because of inappropriate site, insufficient facilities, and deficient programme for practical use. In conclusion, the paper reconfirms importance of ecological learning-place within grounds of primary school in terms of its educational, social and ecological effects, and suggests briefly some measures to encourage its construction and practical use.

Visual place recognition is widely researched area in robotics, as it is one of the elemental requirements for autonomous navigation, simultaneous localization and mapping for mobile robots. However, place recognition in changing environment is a challenging problem since a same place look different according to the time, weather, and seasons. This paper presents a feature extraction method using a deep convolutional auto-encoder to recognize places under severe appearance changes. Given database and query image sequences from different environments, the convolutional auto-encoder is trained to predict the images of the desired environment. The training process is performed by minimizing the loss function between the predicted image and the desired image. After finishing the training process, the encoding part of the structure transforms an input image to a low dimensional latent representation, and it can be used as a condition-invariant feature for recognizing places in changing environment. Experiments were conducted to prove the effective of the proposed method, and the results showed that our method outperformed than existing methods.

Previous U-Commerce researches have dealt with the business support systems for traditional commerce space such as real world shopping malls. This paper investigates U-Commerce business models in service space. The McDonald's Touch-Order case is analyzed from business model perspective and the Media-Embedded Place business model is introduced as a U-Commerce business model for value creation in service space. The media-embedded place business model attaches auto-identification tags to tables or billboards, triggers commercial transaction through the tags, and shares the revenues and the incentives among the place owners and commerce/content providers. This paper analyzes its scenario and applications and illustrates the profitability analysis using so-called 'tag evaluation model'.

Space in the past had characteristics of place which are required for specific behavior to be done as we recognized it easily. However, for space in modern times, the purpose, forms and behavior space has, have changed as tools comprising the space have changed. 'Virtual space' which has been a conversation topic recently is unspecific and changeable space whose forms and geological location are not defined clearly. In addition, behaviors caused by this virtual space in combination with real space are taking place. The nature of Flash Mob which is one of the typical behaviors which take place starting from virtual space to be connected with real space, is that it is intangible game culture whose forms and behaviors are not fixed, and it is not limited to a specific place. Besides, Flash Mob is characteristic of representing game culture in modern society, and its nature can be summarized as temporariness, non-placeness, anonymity, double-sidedness and so forth. Since events generally take place in every place when man is involved in space, it's possible to generally think events derived from interpersonal relationships between man and man. We are to study spatial characteristics of Flash Mob by analyzing features and cases of the Flash Mob by means of them.

The researches and discussion for regenerating the deprived urban residential areas are proceeding actively. But urban agriculture is regard as a simple tool for participation of resident and its value as primary industry is discussed in part. Now discussion about increasing the place capital is needed to overcome the existing urban development methods that maximizes the space capital as a new alternative. So this research is to give a theoretical basis for sustainable urban regeneration. It studies the place value improvement through urban agriculture which is applied creative industry convergence. For these, it indicates problems of the methods of existing urban development, reveal the strengths of urban agriculture applied creative industry convergence in the aspect of place value improvement, and suggests a new paradigm for urban regeneration.

Let K be a real function field over a real closed field F. Then there exists an F-place .phi.:K.rarw.F.cup.{.inf.}. This is Lang's Existence of Rational Place Theorem (6). There is an equivalent version of Lang's Theorem in (4). That is, if K is a function field over a field F, then, for any ordering P$_{0}$ on F which extends to K, there exists an F-place .phi.: K.rarw.F'.cup.{.inf.} where F' is a real closure of (F, P$_{0}$). In [2], Knebusch pointed out the converse of the version of Lang's Theorem is also true. By a valuation theoretic approach to Lang's Theorem, we have found out the following generalization of Lang and Knebusch's Theorem. Let K be an arbitrary extension field of a field F. then an ordering P$_{0}$ on F can be extended to an ordering P on K if there exists an F-place of K into some real closed field R containing F. Of course R$^{2}$.cap.F=P$_{0}$. The restriction K being a function field of F is vanished, though the codomain of the F-place is slightly varied. Therefore our theorem is a generalization of Lang and Knebusch's theorem.

The core of character and concept in an exhibition space of contemporary museum is that the place for relics and materials changes into the place for spectators, the static exhibition place changes into the dynamic exhibition place, and the place for learning naturally during amusement. In other words, it could convey the conceptual exhibition object which is not the material object called a relic, it could be a place where is to investigate, participate, experience and enjoy with easily method to general public, and ordinary people are supposed to experience with integrative the world of intellectual, cultural and artistic which is inconcionsly rising a dimensiov. In order to response positively the change of these exhibition concept itself, exhibition system will be established through the analysis of realistic exhibition objects with the visulatization of theme or thought of an exhibitiov. In process of conveying image, the effective and concrete exhibition method and technique should be measured in order to realize the communication between spectators and exhibition objects. The purpose of this study is to find the methodology which is enable to establish the exhibition theme and presentation system through the selection and analysis of exhibition objects in major cases of a musem of ecience and engneering, to find the process model till the methodology applies to the space scheme, and to find finally the designed indicators which is applicable to the progress of exhibition desigv.

The purpose of this study is to elicit the planning factors for the embodiment of sense of place in public library. This study analyzes qualitatively the good places where the children seek for and evaluate in children's library. The primary method of survey in this study is the caption evaluation. The survey is conducted in libraries of three types. In the caption evaluation, children take good places into photograph by themselves and are asked for reasons, features and physical characteristics for the pictures on good places. Through the study of the preceding studies, this study takes four analysis frames, Path, Occupancy Place, Edge and Mark. According to four analysis frames, the principal features, physical characteristics and the examples in libraries of domestic and foreign country are put in order. The meanings of this study are summarized as followings; presenting the method of user's positive evaluation, studying the sense of place in children's view point, and presenting the interrelation pattern for embodiment of the rich sense of place.
