We are sure that Abakanowicz positively assumes a position of members, which are represented the later modern fabric design. In sprite of his pervasive evaluation, we have doubt about his achievement because the preceding research is insufficient about argumentsuch as dependence on intuitive emotion study, conventional analysis of structure and insufficient inquiry of causa efficiens. We agree that basic structure of is dissipation. Though right and left symmetrical structure is similar, also that structure is different. We can't decide whether structure is unification structure, difference structure or mixture structure . We think that the time of confusing argument of his structure is changing period for disorganization trend. The result of this study confirm the research possibility about space organization with restructure analysis and verification for examining essence structure of sample text . The Thesis are concern that the different between paradigmatic appearances and syntagmatic, which exist . So, we can approach the meaning of system and find dominent point about constructional relationship on the works. The meaning of dominent point is understood about sexless trend or Androgyne, which are appeared Abakanowicz forth work period. The relationship structure which is mixed both issue show that inner issue of work is located the highest position. The paper presents confusing manufacture system, which are suggested man-woman sex and mixed meaning. The other result of this study are, 1. being known as Abakan algorism, Abakanowicz has new drafting idiom from his ancient belief. 2. we need to research the body texture of Abakanowicz with the trend of restructure of body study. 3. we need argue about gender study in relative with poster moderntheology related problem of sexlessness people and perfect sex-people.

The Chapel and Exhibition hall of Chul-du-san-Holy place are considered as the most important work of architect Lee Hee-Tai (1925-1980), and as a work representing Korean architecture in 1960's. What is the reason that these buildings can acquire such a remarkable estimation? This study tries to make clear this reason with an analytic method. These buildings are situated in singular site, in which small mountain comes up alongside with Han-river. Architect laid out the Chapel and Exhibition hall to the memory of 108 saints who died for their faith in this mountain, considering the specificity of the site, the direction of approach stair, and the formation of public space. Architect proposes an opposed composition of form for these two buildings. So the Exhibition hall is characterized by trabeated structure, centripetal force and Apollonian order. It has strictly proportioned facade, which is composed of two 15m-by-l5m squares and subdivided equally in three portions. The Chapel is charaterized by arcuated structure, centrifugal force, and Dionysosian sentiment. In this work, architect Lee Hee-Tai also expressed the locality of Korean architecture with the grammar of column-roof.

This paper presents a method to retarget a source motion to the rig-space parameter for a target character that can be equipped with a complex rig structure as used in traditional animation pipelines. Our solution allows the animators to edit the retargeted motion easily and intuitively as they can work with the same rig parameters that have been used for keyframe animation. To acheive this, we analyze the correspondence between the source motion space and the target rig-space, followed by performing non-linear optimization for the motion retargeting to target rig-space. We observed the general workflow practiced by animators and apply this process to the optimization step.

Pointing to the design requirement of prestressed space grid structure being the target cable force, the pretension scheme decision analysis method is studied when there's great difference between structural actual state and the analytical model. Based on recursive formulation of cable forces, the simulative recursive system for pretension process is established from the systematic viewpoint, including four kinds of parameters, i.e., system initial value (structural initial state), system input value (tensioning control force scheme), system state parameters (influence matrix of cable forces), system output value (pretension accomplishment). The system controllability depends on the system state parameters. Based on cable force observation values, the influence matrix for system state parameters can be calculated, making the system controllable. Next, the pretension scheme decision method based on cable force observation values can be formed on the basis of iterative calculation for recursive system. In this way, the tensioning control force scheme that can meet the design requirement when next cyclic supplemental tension finished is obtained. Engineering example analysis results show that the proposed method in this paper can reduce a lot of cyclic tensioning work and meanwhile the design requirement can be met.

This work proposes structure of spring backbone micro endoscope. For effective surgery in narrow and limited space, many manipulators are developing that different to existed structure. This device can move like elephant nose or snake unlike the existing robots. For this motion, a mechanism that uses spring backbone and wires has been developed. The new type endoscope that has Z axis motion for spring structure, therefore it has 3 degree of freedom, two rotations and one linear motion. And new kinematics for backbone structure is proposed using simple geographic analysis. The Jacobian and stiffness modeling are also derived. Exact actuator sizing is determined using stiffness model. Finally, the proposed kinematics are verified by simulation and experiments.

The procedure of design for reliability which consists of reliability analysis and Failure Modes and Effects Analysis(FMEA) is established and reliability assesment is performed for the nano-satellite air-launching rocket, Mirinae II. By means of using the reliability analysis result, the feasibility to insert the Mirinae II to the target orbit for given mission time under operating environment is assessed. During the reliability analysis process, the system is categorized by Work Breakdown Structure(WBS), and reliability structure is defined by both Reliability Block Diagram(RBD) and schematics of the system. FMEA is used to determine the risk priority number of components and parts. The target reliability is satisfied by changing the design of components and parts with high-risk, hence the design for reliability to put the satellite in to the target orbit safely has been performed.

Nowadays in building construction field, workers become aged and avoid dirty, difficult, and dangerous work. Above all, a person who is in charge of beam assembling work in high and narrow space just relies on safety belt. So these workers should be highly trained. This paper deals with a new locomotion robot that can take this in charge, which will be able to provide less labor costs, less time to build a building and safer environments for workers. The geometric features of steel structure in building construction were carefully analyzed and developed a locomotion mechanism optimized to it. The robot was designed to be rugged, strong, and fast rather than having excessive mobility. Feasibility of the developed robot was verified through experiments.
