Having taken actions for 2 years, Net Neutrality User Forum has realized Net Neutrality as a international issue of future Internet. Although the Internet design principle (layering, module, IP protocol) has enabled the end users to communicate each other without any additional permission or interference, in the reality, the end users have been tracked by both companies and governments, and the communications could be blocked, or restricted by surveillance devices, such as DPI, which could change the whole Internet design principle. Given that the Internet is a large community of the equal end-users based on end-to-end principle, it's essentially the issues of the whole Internet users, rather than of one nation, and we should focus on developing the transparent and participatory ways in Internet governance. The current Internet governance discussion have taken placed in ICANN, IGF, etc., in bottom-up processes of multistakeholderism to reflect the views of end-users. However there have been the controversial issues in Internet Governance, such as the position of government as a stakeholder, global north-south problem, transparency, so we have faced the debate on the new or evolving frame of Internet governance.

Squash & Stretch principle is playing an essential principle for animation action. The application of this principle gives the illusion of weight and volume to an animation character, and makes it possible that an animation action be the smooth and soft by escaping from the stiffness and rigidity. If an action of human or object on animation is expressed like a real world, it seems to be unnatural. Any action without Squash & Stretch will look rigid, uninteresting and not alive. It can be applied to movement of all objects, characters' actions, dialogues and facial expressions with a basic rule of mass, volume and gravity. Any action will not be well expressed without this principle. To be a good animation action, it should be deeply applied in 3D animation, not only 2D animation. Thus, a systemic analysis of Squash & Stretch principle is required.

Frei Otto, who is called to be the father of the ecological architecture, has shaped a peculiar architectural form style. In distance from the formalistic persistence to the modernist form canon and the postmodern tendencies to the self-representation of architects, Frei Otto has taken a more fundamentalistic position. Through the interdisciplinary researches on the self-organizing processes in the nature and the technical world Frei Otto could reason with architects, engineers, biologists, historians and philosophers the principle and structure of the natural construction that is applicable to the morphological research and the architectural construction research. In the middle of his architectural and scientific works is the idea of 'the natural construction' situated, and the basic principle and instrument of this 'Die Prinzip der Selbstbildung, The Principle of Self-making'. Founding himself on this principle, Frei Otto seeks after the new architectural form that is light, natural, flexible and variable by reasoning the typical formation process which refers to the common denominator of the self-making processes in the nature, the technique and the architecture. Despite his architecture is to be called to the anonymous, his architectural vision is headed toward the rationalistic form in accord with the natural laws. This study is purposed to elucidate the constellation to which his scientific attempts belong and the theoretical and methodological foundations of his architecture of 'the natural construction'.

When the existing polder levee was constructed, the river's numerical analysis decided the bank raise by applying the planned flood stage or by using the result from the sectional 1st dimensional numerical analysis. But, it was presented that there is a limitation in the 1st dimensional value analysis when the structure like the polder levee obstructs the special shaped running water flow. Therefore, in order to verify the numerical value applicability when the polder levee is constructed, this report compared each other through the 1st and 2nd dimensional numerical analysis and the mathematical principle model laboratory. In case of the polder levee construction through the numerical analysis and the mathematical principle model laboratory, it was decided that there was no big problem in the 1st dimensional numerical analysis applied design, considering the uncertainty of mathematical principle analysis though the first dimensional numerical analysis was calculated a little bigger than the second. But, after construction, it was found that the water level deviation of the 1st, 2nd occurred biggest at the place where the flow was divided into two. Also, as a result of comparing the 1st, 2nd dimensional numerical analysis with the mathematical principle model laboratory, it was confirmed that the 1st numerical analysis applied design decreased the modal safety largely, as the left side water level was calculated smaller more than 0.5m in case of the 1st dimensional numerical analysis.

In contemporary society, Labyrinth and maze are used with the same meaning. They are also used by translating various meanings. But labyrinth and maze are exactly different meaning. The purpose of this study is to inquire about difference for understanding essential meaning between labyrinth and maze. First of all, this study is to grasp composition principles and the characteristics of space through example of labyrinth and maze from ancient to contemporary, prescribe about essential meaning between labyrinth and maze and examine contemporary architecture which is fit for essential meaning. As compositional Principle in labyrinth and maze applied to comtemporary architecture, the labyrinth are centrality, property of one-sideness, determinable space, on the contrary the maze are out of centrality, property of multi-sideness, indeterminable space. Finally, The aim of this paper is analyze exhibition space that suit to the characteristics of composition principle and find the characteristics in labyrinth and maze. Examples of exhibition space are Aldo Van Eyck's 'Sculpture Pavilion', Kazuyo Sejima's '21st Century Museum of Contemporary Art', Ben van berkel's'Museum Het Valkhof'. These research we studied the visitor's circulation and the architectural structure in exhibition space with the spatial characteristics and the compositional principle in labyrinth and maze.

In order to develop a medium voltage class gas circuit breaker by our own technology, we designed and manufactured the model interrupters using the hybrid arc extinguishing principle which adopts the thermal expansion principle in the large current region and the arc rotation principle by permanent magnet in the small current region. As the results of the first year research out of three years' research period, the main design parameters such as the volume of thermal expansion chamber, the distance between fixed contact and nozzle, the length of nozzle throat, the nozzle expansion angle and the magnitude of permanent magnet etc. have been determined. 4 types of model interrupters have been designed and manufactured considering the main design parameters. The 25kA short-circuit test and capacitive current breaking test have been performed for the model interrupters and the test results analyzed to improve the model interupters.

As the software development cycles is getting shorter, the software reusability is emphasized accordingly. Specifically, the design reusability is being recognized as one of the most important factor to increase the software quality and productivity and make the maintenance cost down. Two essential abilities are needed to improve the design reusability. One is the identification of the reusable objects, and the other is the organization of the relationships among the objects. However, the existing methods using such as a grammatical analysis, a scenario matching and a unit of design problems(design pattern) have not been proposed proper principles to identify the reusable objects on the basis of the abstraction which is the core of the object-oriented concept. In this paper, we will offer the Two-Pass abstraction principle based in the abstraction concept.

The purpose of this study is to analyze the facility standards of the elderly welfare facilities applying the seven principles of the universal design. The facility standards of the elderly welfare facilities were limited to the provisions of the "Enforcement Regulation of the Elderly Welfare Act". There are few legal regulations applying the universal design in the construction of the elderly welfare facilities. The facility standards are set only with the minimum requirements such as securing the safety of the user, securing the space area, functional convenience, and risk prevention. However, the contents of the regulations are limited to the minimum standards for functional convenience and safety required for living. In conclusion, in the elderly welfare facilities, the notion of universal design, which considers not only the elderly, but also service providers, employees, and general visitors, should be considered.
