(Background and Purpose)Surface spaces that embrace a range of environmental variables play a mediating role that directly connects with humans and enables continuous morphological change. Understanding the context and relations between spaces and surfaces and trends by theoretically studying holonic structure will provide a framework. This framework does not adhere to the outdated conception that drawing boundaries is a finishing material, and lays a foundation for understanding a ubiquitous surface that can respond to all environmental conditions. In this regard, this study analyzes “elements of relations” in terms of how designs can be created according to human expectations and environmental conditions. (Method) By understanding the quadrant elements of holons, surfaces can be seen to have physical functions that adapt to the demands and expanded language of roles, which can trigger social and cultural value. All types of holons can be formed and destroyed by certain relations, so understanding quadrant traits within these relations is crucial. As such, although a surface is an artificial system of cortical functions established by human needs, since surfaces are closely related to concepts and institutional change, they can evolve into open systems that can immediately respond to surroundings. By understanding quadrants, thus, surfaces can be regarded as organisms, or “live systems;” therefore, this study examines surfaces from the perspective of philosophers who questioned existence. This study classifies the elements of surfaces as live systems and analyzes module systems using an intelligent methodology that incorporates a variable, structural, expressive, and functional approach. In addition, this study attempts to understand the relative traits of surfaces by using the characteristics of intentional, behavioral, social, and cultural aspects that arise within quadrants. (Results) Six surface construction cases are analyzed using a module approach in terms of the virtual side and physical side, which exposes the hypothetical nature of shapes, including tectonics “knowledge” and “demonstration,” and the “interior side” and “exterior side” of holon quadrants. The results show, first, that surfaces with correlative characteristics play a connecting role. Surfaces that used to have single function now play the role of organic media with hypothetical and physical capabilities. Second, surfaces can easily accelerate change or restructuring using module systems; thus, surfaces have existing values as sensitizers, which can lead to lasting change. (Conclusions) By correlatively and contextually understanding the influence on each other, the potential value of a surface can be estimated. Surfaces are continuously involved in a process of physical change according to conditions. Based on this understanding, it is predicted that surfaces can gradually transform to open systems that can sensitively read the environment. By setting up a module system within a space structure that is difficult to keep up with temporality, the system can be design methodology with variability. In this regard, vitalization of surfaces using the module system can be expected.

Antarctica is important area in order to understand climate change. In addition, this area is complex region where indicate warming and cooling trend according to previous studies. Therefore, it is necessary to understand the long-term variability of Antarctic energy budget. Net radiation, one of energy budget factor, is affected by albedo, and albedo cause negative radiative forcing. It is necessary to analyze a relationship between albedo and net radiation in order to analyze relationship between two factors in Antarctic climate changes and ice-albedo feedback. In this study, we calculated net radiation using satellite data and performed an analysis of long-term variability of net radiation over Antarctica. In addition we analyzed correlation between albedo. As a results, net radiation indicates a negative value in land and positive value in ocean during study periods. As an annual changes, oceanic trend indicates an opposed to albedo. Time series pattern of net radiation is symmetrical with albedo. Correlation between the two factors indicate a negative correlation of -0.73 in the land and -0.32 in the ocean.
