  • Limbs and supporting structures of an organism experience a full weight of its own when it lands from water, because neutral buoyancy in the aquatic habitat will be no longer available in the terrestrial world. Metamorphosis of anuran amphibians presents 8 good research model to examine how this transition from non-loading to weight-loading affects development of motor capacity at the time of their first emergence on land. Our video analysis of the transitional anurans, Rana catesbeiana, at Gosner stage 46 (the stage of complete transformation) demonstrated that the take-off speed increased 1.23-fold after the first six hours of weight-loading on the wet ground. It did not increase further during the following three days of loading, and was close to the level of mature frogs with different body mass. During development of larvae in deep water with no chance of landing through metamorphosis, both tension and power of a hindlimb anti-gravity muscle increased 5-fold between stages 37 and n. However, the muscle contractility increased more rapidly when the larvas could access the wet ground by their natural landing behavior after stages 41-42. Muscle power, one of major factors affecting locomotory speed, was 1.29-fold greater in the loaded than in the non-loaded larvae at the transitional stage. Thus, weight-loading had a potentially significant effect on the elevation of motor capacity, with a similar extent of increment in locomotory speed and muscle power during the last stages of metamorphosis. Such a motor adjustment of the froglets in a relatively short transitional period would be important for effective ecological interactions and survival in their inexperienced terrestrial life.

  • In Alvar Aalto's designs, important factors of complex building designs including Wolfsburg cultural center are that they insinuate how to develop each architectural type and how to combine them in a building. The humane and physical background studies, and wholistic and systematic approaches are adopted to fulfill research purposes. Comparison with other buildings are necessary to reveal true meaning of this building. The result of analysis show characteristics of Wolfsburg cultural center as follows; hybrid composition of mass and elevation, spatial effect using level difference and light, massing variation of roof, and creating space for various activities. Wolfsburg cultural center designed in late 1950s has greatly affected Aalto's later works through various architectural experiments because it is the first cultural complex project that combined various architectural types. Especially library in the cultural center has shown transitional characteristics to famous fan-type libraries of 1960s while maintained features about Viipuri library. Wolfsburg cultural center act as an another type which present new principles of clustering, massing and exterior design. Its true meaning lies in forming a humanizing place beyond spatial configuration.

  • The purpose of this study was to examine how the interface between "place of work" and "place of living" in the housing sphere has changed, and to understand its social background. During the korean modernization period, changes in economic structure toward industry has an influence on many aspects of modem life in addition to occupations. The traditional mixing of heterogeneous activities in the home-such as between reproduction and household affairs, first changed into a coexistence of two spaces with different functions within the boundaries of home, and finally into a spatial separation between functions in an urban dimension. As a result of this process, the primary role of the modem home is as a place for relaxation without work. One important kind of home, in which a retail shop is integrated with it, was researched as a transitional form. Its spatial layout showed a various combined usage of both spaces. In conclusion, changes in relevant macro-social aspects are very concretely reflected m the function and spatial organization of the home.

  • Purpose: The purpose of this qualitative study was to explore the transition experiences of the elderly from long-term care hospitals to their homes. Methods: The participants were eight elderly medicaid beneficiaries, who had been the subjects from the community care project in Korea. The data were collected with one-on-one interviews from April to November in 2020, and analyzed by phenomenological steps. Results: The seven themes derived in this study were 'Space to escape', 'Reliable supporter opened the way to discharge', 'Comfortable life at home', 'Obstacles to independent life', 'Struggling to live alone', 'Fence for community life', and 'Energizing in daily life' Conclusion: The results revealed the positive aspects of Community Care program in Korea. However, it is suggested that active communication between hospitals and community care institutions, and improvement of home environment to live in the community before discharge should be required. And system revision is needed to adjust activity in their home and support health problems of the elderly in the early stage of discharge. The results of this study can be referred to as the foundation of transitional care for the elderly.

  • This study aims to analyze chlidcare philosophy and the architectural characteristics of communal childcare cooperative nurseries(parent cooperative childcare facilities), and also to examine their mutual relationship. The communal childcare cooperative is an ideal childcare method to break away from employee-supported childcare system and cooperatively solve childcare problems in the family community system. The child-rearing philosophy of the communal childcare can bring spontaneous and creative development amidst 'daily life' and 'play' by switching from knowledge and skill-oriented education and puts an emphasis on physical environments in child's growth. The features of architecture related the childcare philosophy derived from this study are as follows: the way of participation and self-help, the extension of spatial scope and focuses on outside space, architecture of house-like residence rather than educational facility, spatial 'overlapping' focusing on transitional space and multi-purpose space rather than spatial partitions, the pursuit of creativity through play is realized in the incompletion and unspecification of space evolving over time.

  • Fossil galaxy cluster has a dominant central elliptical galaxy (${\Delta}M12$ >2 in 0.5Rvir) embedded in highly relaxed X-ray halo, which indicates dynamically stable and passively evolved system. These features are expected as a final stage of the cluster evolution in the hierarchical structure formation paradigm. It is known that Abell 2261(A2261 hereafter) is classified as a fossil cluster, but has unusual features such as a high central X-ray entropy (i.e., non-cool core system), which is not expected in normal fossil clusters. We perform a kinematic study with a spectroscopic data of 589 galaxies in the A2261 field. We define cluster member galaxies using the caustic method and discover a new second bright galaxy at ~1.5 Rvir (nearly the splash-back region). It implies the current fossil state of the cluster can break in the near future. In addition, with three independent substructure finding methods, we find that A2261 has many substructures within 3 Mpc from the center of the cluster. These findings support that A2261 is not in a dynamically stable state. We argue that A2261 is in a transitional phase of dynamical evolution of the galaxy cluster and maybe previously defined fossil cluster does not mean the final stage of the evolution of galaxy clusters.

  • Recently, a lower levels space has turned into a mediating space where people can experience urban spaces directly and it has revitalized communication between the city and company and also it has changed itself newly. In addition, this space which is connecting interior and exterior spaces of company's buildings can attract people living in the downtown as shock-absorbing and transitional space and it is getting more important part in urban context these days. Through case studies of corporate office space planning characteristics derived lower levels and to provide direction for the lower levels of the corporate office space planning purposes of the present study. Therefore, I establish the concept of the public good corporate office space and transition space, the concept of transition through the first Theoretical Methods. I investigate the properties of the transition area is used as the target for completion of the current construction culture destination since 2000, winning the corporate office, I have been talking about the characteristics of the corporate office along the lower part of the last PPS assessment criteria to apply to the building. PPS by applying an assessment factor can be derived for building enterprise case studies and analysis of the results the following conclusions about the use of publicity and transition space. First, lower levels of corporate office space had been applied to the use and activity in a very important project characteristics. Second, corporate office space, lower levels of access and linkages are important. Finally, in terms of public characteristics transition space is a important characteristic for low-rise space of headquarter buildings.

  • The purpose of this study was to explore the learning effects in elementary school students who participated in a geological field trip conducted under the theme 'minerals and rocks', focusing on novelty space. A total of 10 sixth-grade students participated in this program held at a public elementary school in Seoul as part of after-school club activities. Students observed mineral and rock samples in a classroom and outdoor learning environment. The authors collected activity papers (texts, drawing), researchers' participation notes, video and audio recordings containing the study participants' activities, and post-interview data To analyze the learning effects in the cognitive domain of students, the observation analysis framework for rock classification of Remmen and Frøyland (2020) and the rock description analysis framework of Oh (2020) were used. Additionally, to explore the learning effects of psychological and geographic areas, students' drawings, texts, discourses, and interview data were inductively analyzed. The results showed that the students demonstrated 'everyday' and 'transitional' observations in the classroom learning environment, while in the outdoor learning environment (school playground, community-based activities), they demonstrated 'transitional' and 'scientific' observations. Moreover, as the scientific observation stage progressed, more types of descriptive words for rocks were used. In terms of psychological and geographic aspects, students showed their selection of places to explore familiar outdoor learning environments, positive perceptions of outdoor learning, and aesthetic appreciation. Finally, this study not only discussed novelty space as a tool for analyzing students' learning effects but also suggested the need for an academic approach considering new learning environments, such as learning through virtual field trips.

  • In order to understand the configuration of magnetic field producing a solar penumbral microjet that was recently discovered by Hinode, we performed a magnetohydrodynamic simulation reproducing a dynamic process of how that configuration is formed in a modeled solar penumbral region. A horizontal magnetic flux tube representing a penumbral filament is placed in a stratified atmosphere containing the background magnetic field that is directed in a relatively vertical direction. Between the flux tube and the background field there forms the intermediate region in which the magnetic field has a transitional configuration, and the simulation shows that in the intermediate region magnetic reconnection occurs to produce a clear jet- like structure as suggested by observations. The result that a continuous distribution of magnetic field in three-dimensional space gives birth to the intermediate region producing a jet presents a new view about the mechanism of a penumbral microjet, compared to a simplistic view that two field lines, one of which represents a penumbral filament and the other the background field, interact together to produce a jet. We also discuss the role of the intermediate region in protecting the structure of a penumbral filament subject to microjets.

  • In his non-hierarchical approach to art making, Robert Irwin questions how art is made. In the process, he seems to come down on both sides of the Modernism versus Postmodernism debate. Insofar as he wants to advance the avant garde tenets of modern art, he can be thought of as a modernist. But insofar as he denies Modernism's claims for transcendental status, he can be thought of as a postmodernist. Irwin's light and space environments, in particular, are conditioned by their basic attachments to their surroundings. They reveal the commonplace, but largely overlooked, richness of visual perception. By encouraging his viewers to open their eyes, Irwin wants them to engage in an act of looking, one that manipulates the basic syntax of seeing. This paper discusses Irwin's contributions to the art of his time (basically the transitional period between Abstract Expressionism and Minimalism) using as an example a light and space environment he created as the backdrop for the "First National Symposium on Habitability." This work was later reprised in 1980 as an independent installation. These works are examined to show how Irwin's art displaces modernist notions of authoritative (and authoritarian) quality with postmodernist ideas of direct (and demotic) value.
