The concept of ‘Open Space’ is conceived to be very valuable subject of interest in developing modern settlement system. In Korea, many new and old residential sites have been developed or renewed to fulfil the housing demands. And such trends seem to continue for the time being. What is more, the requirments for more comfortable residential environments, that is deeply concerned with ‘Open Space’, inorease gradually. As a basis for designing more efficent residential environments to fit Korean morden life style, self - grown, traditional and agricultural villages are studied. This study is concenturated on the Open Space System with its socio - cultural and physical backgrounds. For this, data and materials are some widely collected and are analysed focused on the systems and structures of ‘Open Spaee’. Some results from this study are summarized as follow ; 1. It is assumed that the number of houses per village is around 60, and that its area reaches to the radious of 3-4km. 2. ‘POONGSU’is a generally adopted theory based on natural elements like mountians, waters, and orientations when locating villages and composing their spatial structures. As a result of this, the basic structures of villages and Open Space are defined. 3. Circulation system is integrated to the hierachyal order system ; that is, Passing Road \longrightarrowEntry Road\longrightarrowCentral Read\longrightarrowDisperse and Access Road. 4. The natural and agricultural land uses are overlapped with diverse outdoor activities - religious services, play and recreation, relaxation, etc - without any physical modification. 5. At each villages, several artificial and spot - like green facilities are found. And distinctive functions, meanings, and locationalities are given to each of them. On that, they become a visual and psychological centers of each village. 6. In addition to its basic function of circulation, Central Road takes the sence of place for outdoor activities. Because of this charactor, it plays an important role of activating the village life and binding the various Open Space elements.

The subject of this research is to analyze the design characteristics of outdoor spaces in Good Design awarded apartment complexes in the past decade. The results are as follows. First, the overall outdoor space design theme, one of the conceptual elements, is focused on both 'nature' and 'story of various subject' that are similar to each other. Second, the case study object with the visual openness, which is secured between apartment blocks, is shown frequently in case box-shaped apartment blocks are arranged in a row. However, in case of Y-shaped block arrangement, the visual openness secured within an apartment complex is considered more important. Third, according to the result of circulation/ inner path element, the most frequently appeared inner path form is a grid pattern with straight path emphasis. While apartment complexes with the parking lot on the ground are only 3 out of 18 cases, it with circulation path for vehicle on the ground level are over 61%. Fourthly, the design characteristic of social space of physical outdoor design appears to be 'central link facility type'. In this case, the central community facilities are more likely to be combined with various functions, such as green, water, and social connection. Fifthly, in case of natural space, most of the apartment cases are shown over 45% green area ratio with wide green and water space provision. Especially, the differentiation is to provide the space where can stimulate a resident's participation.

We present the results of high-resolution (R ≥ 30,000) optical and near-infrared spectroscopic monitoring observations of a FU Orionis-type object, 2MASS J06593158-0405277. We have monitored 2MASS J06593158-0405277 with the Bohyunsan Optical Echelle Spectrograph (BOES) and the Immersion GRating INfrared Spectrograph (IGRINS) since December 2014. Various features produced by wind, disk, and outflow/jet were detected. The wind features varied over time and disappeared about a year after the outburst occurred. The double-peaked line profiles were detected in the optical and near-infrared, and the line widths decrease with increasing wavelength. The disk features in the optical spectra are fit well with G2-type or G5-type stellar spectra convolved with a disk rotational profile of about 45 km s^-1, which corresponds to a disk radius of about 71 R_⊙for a central mass of 0.75 M_⊙. Disk features in near-infrared spectra are fit well with a K1-type stellar spectrum convolved with a disk rotational profile of about 35 km s^-1, which corresponds to a disk radius of about 117 R_⊙ for a central mass of 0.75 M_⊙. We also detected [S II] and H2 emission lines, which are rarely found in FUors but are usually found in the earlier stage of young stellar objects. Therefore, we suggest that 2MASS J06593158-0405277 is in the relatively earlier part of Class II stage.

In this paper, some new fixed point theorems for condensing mappings are established based on a well known result of Petryshyn. We use several Leray-Schauder type conditions to prove new fixed point results. We also obtain generalizations of Altman's theorem and Petryshyn's theorem as well.

In this paper, we obtain that every biharmonic non-degenerate hypersurfaces in semi-Euclidean space $E^5_s$ with constant scalar curvature of diagonal shape operator has zero mean curvature.

In this study we analyzed and interpreted the phenomenologlcal characteristics and meanings of water space in religious architecture through field studies and phenomenologlcal approaches, focusing on the religious architecture Introducing water space in contemporary architecture. The phenomenological experience elements of the research ate light, time, place and context. As the results of this study, first, light as a phenomenological element not only induces a contrast and change between light and the shadow in architectural space and various changes of light in inner space, but also operates as an element which expresses building features outward with time. Second, time as a phenomenological perception experience makes us feel changes of the environment and physical properties and experience space visually and physically. The continuity of time shows the change of a day, night and daytime and seasons. Third, water space makes the sense of place more remarkable, connected closely with surrounding nature In outer space, and creates a new space. Fourth, water space is a contextual element which harmonizes with surrounding environment by connecting surrounding natural environment with architectural space. Fifth, water space in religious architecture is a symbolic and central element, and emphasizes the atmosphere of architectural space. In addition, it makes the people who experience water space perceive the place by triggering sensitive response.

Aldo Van Eyck and Herman Hertzberger explained 'In-between space' as an intermediate space between opposite elements such as whole and parts, inside and outside, open and close, central and decentral. From this idea, the meaning of 'in-between space' has developed and applied to works of Bernard Tschumi and Sou Fujimoto. In this study, the meaning of 'in-between space' was compared and analyzed based on two architects' works to reveal the design approach in terms of 'in-between space' Final Wooden House, N House, and Serpentine Gallery Pavilion among Sou Fujimoto's work were selected and Le Fresnoy, Lerner Student Center, and Acropolis Museum among Bernard Tschumi's work were selected to analyze. To understand their design approach, their works were compared and analyzed in architectural attitude, tools, construction style and the approach, concept, theme, relation, direction of in-between space. As a result, Sou Fujimoto uses 'in-between space' as a nebulous approach as intermediate space between opposite elements. For Bernard Tschumi, 'in-between space' is also an intermediate space to emphasize and make a tension between opposite elements. It is a method of solving the contradiction condition between old city environment and new architecture.
