All creatures are living in the space and time. As the space and time are prior to experience, they are preconditions for an incident to happen and preconditions for each other to coexist as well. Therefore, time can be recognized through the change of space and the space can be understood by the passage of time. In western philosophy, the space was understood as an object, place, interval, mind and etc. In oriental philosophy, even though one space is just a part of bigger space, the space may represent the universal space, and the various spaces are no more than a space. The space itself doesn't have any color, form, beginning and end, or liu-he(六合). However, it is the biggest concept that we can find everywhere. In order to understand the space, we need to find our position by expressing subjective positions like above and below, left and right, before and after, and objective positions like high and low, east and west, south and north. In oriental philosophy, the sun is the standard point in finding position; its front side is south, the backside is north, the left side is east, the right side is west, the upper side is south and the lower side north. Based on the finding position which is stated above and by taking each characteristics of he-luo-xi-wen(河洛羲文) and interrelations among them, the space can be modeled. Followings are the results obtained from this study: Tian doesn't fill in west and north. Di doesn't fill in east and south. Tian-dao(天道) turns to left, and Di-dao(地道) turns to right. There is no direct way to get to Dui-chong-fang without passing by Zhong-gong(中宮). The solid figure of eighty-one Bian-ju(變局) and sixty-four Gua-tu(卦圖).

In the Digital Convergence era, the center of social networking is moving into on-line space. This means also that space for public is moving into the on-line space. Along with this, spaces in commercial area, offered as attraction factors, are taking a role as a public space. So, this paper defines these spaces mentioned above as public space and the like. Liberal and affluent communication of Digital Convergence has caused in new spatial cognitions such like, constant social space, flowing space, temporary space, and multiple space. This means the hybridization of on-line and off-line space and the advent of public convergent space. However, it is on-line-centered convergence and has positive effects and negative effects on relationship. This paper suggests the optimization of public convergent space to solve the problems and make better a public space for relationship. For achieving this, social disclosure is grasped as the common way to start relationship both off-line and on-line, and it is proved that social disclosure has three characters such as self-presentation, corporeality, and subjectivity. Subsequently, the differences of the roles of off-line and on-line space are separated by each individual character. These are self-presentation of performance vs. storytelling, corporeality of embodiment vs. disembodiment, and self-subjectivity vs. inter-subjectivity. By recognizing that there are multilevel spectrums between the formers and the latters, this paper presents the direction of the spatial configuration of public convergent space which offers the right of manipulation of self-disclosure. It will be used for presenting the prototype of public convergent space.

The purpose of this study is to look for an environmental design method based on open narrative structure, and to promote various experiences and interpretations of space through user's engagements. That is to say, the designer does not lead specific events through separate Boning but using the continuous open composition users are provided with margins for their imaginations. Spatial formulation through open narrative structure gives us various thoughts and it plays an important role in making a sequential space. Like an abstract painting, it is a complex story making or arranging a montage of images containing stories that elicit the reader's engagement through diverse interpretations. Like this, open composition exists in an ambiguous state and it is possible to interpret unfinished‘evolving work’within it. Utilizing open narrative structure, this study attempts to apply the idea of sequencing and open composition in the case of designing Arirang Culture Park. Open composition should induce various engagements by users and could be a medium which organically connects nature, culture and people. The spatial strategies of‘ambiguity’ and‘transparency’are like a bundle of complex and heterogeneous factors. Finally, the study focuses on the ‘integration’of the main ideas that compose multilayered space. ‘Voidness’and‘thickening’are also used for spatial strategies in open narrative structure. As alternative plans for undecided programs of the space, the voidness can be a strategic design program with flexibility about changes of futures. Also, thickening can be a strategic design program for functional reinforcement of the space, for the dramatic effects and for the generation of incidental events. Although both voidness and thickening seem paradoxical, we can see they are similar in the way that both focus on various spatial uses and by how they do not function as one-to-one correspondence, but as multiple correspondences. Therefore, open narrative structure is possible to apply in designing space and it can be an alternative design strategy for inducing multiple interpretations of space.

Cave on the Moon is considered as the most appropriate place for human to live during the frontier lunar exploration. While the lava flows, the outer crust gets cooled and solidified. Then, the empty space is remained inside after lava flow stops. Such empty space is called the lava caves. Those lava tubes on the Earth are formed mostly by volcanic activity. However, the lava tubes on satellite like Moon and planet like Mars without volcanic activity are mostly formed by the lava flow inside of the crater made by large meteorite impact. Some part of lava tube with collapsed ceiling appears as the entrance of the cave. Such area looks like a deep crater so called a pit crater. Four large pit craters with diameter of > 60 m and depth of > 40 m are found without difficulty from Kaguya and LRO mission image archives. However, those are too deep to use as easily accessible human frontier base. Therefore, now we are going to identify some smaller lunar caves with accessible entrances using LRO camera images of 0.5 m/pixel resolution. Earth's lava caves and their entrances are well photographed by surface and aerial camera in immense volume. Thus, if the image data are sorted and archived well, those images can be used in comparison with the less distinct lunar cave and entrance images due to its smaller size. Then, we can identify the regions on the Moon where there exist caves with accessible entrances. The database will be also useful in modeling geomorphology for lunar and Martian caves for future artificial intelligence investigation of the caves in any size.

From modernism to post-modernism, the practice in the design field often reduced the complexity of environment and to remove variety. However, contemporary ideas of space have been changed. The current thought premise is that the environment is mutable and is evolving according to inner and outer forces and elements. Therefore, leading designers recognize that the environment is complex in itself while anticipating a new theory explaining on-going trends. The idea of fold formulated by Gilles Deleuze can provide a theoretical base for new environmental design in constrat to current design practices. The fold is a hybrid by accommodating complex relations within an object. It carries a dynamic world view through continual process and yields a topological space against absolute space like Euclid geometry. The characteristics of the fold can be paraphrased as rhizome, stratification and smooth space. Rhizome forms a non-hierarchial connection like networking in internet space. Stratification is a kind of superimposition of autonomous potential layers within a single object. Smooth space is a free space and event oriented space keeping non-linear form. This study tried to incorporate the idea of fold to environmental design methods and design process in order to make space which can correspond with complex environment and topological form. In the design process adapted to fold theory, rhizome analysis accepts the complexity of environment and stratification strategy embraces the possibility of accidental use. As a result, the designed park carries a monadic image and produces an ambiguous space. Lastly, smooth space makes topological space unlike Euclid geometry and is free space comosed by the user themselves. Transporting the idea of fold into environmental design could be an alterative way for indeterminate and flexible design to accept new identity of place. Therefore, this study accepts the concept of incidental morphogenesis to make space based on the complexity of environment. The designed space based on the idea of fold searches to create free event space determined by user rather than designated by designer.

The purpose of this study is to understand the architectural space of Gwolnaegaksa (闕內各司), the Government office in the palace, in the early Joseon Dynasty. The Royal palace can be divided into three parts, political space for king, living space for king and his family and government office. So first, we should to understand the characteristics of each space in the Royal Palace. Up to now we have looked at the architectural space of Gwolnaegaksa in Gyeongbokgung (景福宮), one of the Royal Palace, the result of this study is as followings. There were not many Gwolnaegaksas in the early days in Gyeongbokgung. After King Sejong, some office buildings were established in that palace. King's closest guards, like as Seonjeonkwan (宣傳官), Gyumsabok (兼司僕), Naegeumwi (內禁衛) had been on duty in Sajeongjeon Haengrang (思政殿 行廊), a kind of servants' quarters. Bincheong (賓廳), a conference room of high-ranking government officials was situated in Geungjeon Haengrang (勤政殿 行廊). There were also barracks of other palace guards in Geungjeon Haengrang. Gyeongyeoncheong (經筵廳), a place to prepare and wait, was built separately from Geungjeon Haengrang Layout drawings of Gyeongbokgung painted since the 18th century were different from document in some parts. The arrangement of the Gwolnaegaksa was assumed like as the Fig. 9.

The purpose of this research is to obtain an empirically-based understanding of the attitudes of those children and mothers living in three different housing types : detached houses. row houses / villa and apartments. The subjects are 547 elementary school children in the fourth, fifth and sixth grades and their mothers in four different residential areas, Seoul. Followings are the result of this research. 1) Mothers put the first priority on the convenience of the dwelling space from the educational point of view, and they make complaints about their present dwelling space, in particular, children's play and storage space and the size of children's room. 2) They care a lot about the size of housing and, if the size of the housing is held constant, the mothers living in the apartments have more complain about. 3) The difference in the way children and mothers regard their dwelling space is great. The mothers would like to draw a clear line between rest space and play space. They would like to see their children play in their rooms, but children want to make use of the whole space of their housing for play. 4) Mothers think that the children's rooms should be used primarily for study while children think that their rooms have multiple uses such as studying, resting, and playing.

We provide semilocal convergence theorems for Newton-like methods in Banach space using outer and generalized inverses. In contrast to earlier results we use hypotheses on the second instead of the first Frechet-derivative. This way our Newton-Kantorovich hypotheses differ from earlier ones. Our results can be used to solve undetermined systems, nonlinear least square problems and ill-posed nonlinear operator equations.
