Through advanced computer technology, our physical environment became a flexible and liquid space that is a multi-functional space structure, hetero-alliance, formless, interactivity. We attempt to interpretate Deleuze's Other geometry as a space designer. Hence first, the aim of this study is to define the meaning of the Other and Other geometry. Second, to extract keywords out of the Other geometry to analyze the work. Third, to analyze the work using the space formative languages(blob, blurring, distortion, folding, layering, lightness, nesting, repetition, shear, transparency, twisting, unfolding, warping, waving, and weaving). The 13 works were selected which have been issued after year 2000 with the focus on liquid space studies. The methods of this study are literature research and contents analysis. The results of the analysis were as follows. First, the source is the Other who is a hidden potentials in the surrounding environment, and this source has the capability of making it part of reality anytime. Other geometry means it is a theory that is comprised of various lines that with the kind of experiences that one has in life. Second, the key words that were extracted from the theory of Deleuze's Other geometry were of (1)hetero-alliance(reflected in a sculptured shape or a fluid abstract form), (2)dis-form(by speculating the user's movements, and combining space elements with external forces), (3)interactivity (information was exchanged real time between the user and his environment where the space took on a sensory institution). Finally, after studying the works using the space formative languages, we found that blob, warping, waving were used externally, and repetition, warping and waving for mostly used internally.

In composite materials technology, the fiber-reinforced polymers (FRP) have opened up new horizons in infrastructural engineering field for strengthening existing structures and components of structure. The Carbon fiber reinforced polymer (CFRP) sheets are well suited for RC columns to this application because of their high strength to weight ratio, good fatigue properties and excellent resistance to corrosion. The main focus of present experimental work is to investigate effect of shapes on axial behavior of CFRP wrapped RC columns having same cross-sectional area and slenderness ratio. The CFRP volumetric ratio and percentage of steel are also adopted constant for all the test specimens. A total of 18 RC columns with slenderness ratio four were cast. Nine columns were control and the rest of nine columns were strengthened with one layer of CFRP wrap having 35 mm of corner radius. Columns confined with CFRP wrap were designed using IS: 456:2000 and ACI 440.2R.08 provisions. All the test specimens were loaded for axial compression up to failure and failure pattern for each shaped column was investigated. All the experimental results were compared with analytical values calculated as per the ACI-440.2R-08 code. The test results clearly demonstrated that the axial behavior of CFRP confined RC columns is affected with the change in shapes. The axial deformation is higher in CFRP wrapped RC circular column as compared to square and rectangular columns. Stress-strain behaviour revealed that the yield strength gained from CFRP confinement was significant for circular columns as compare to square and rectangular columns. This behaviour may be credited due to effect of shape on lateral deformation in case of CFRP wrapped circular columns at effective confinement action.

This research analyzed acceptability of local public enterprise management assessment targeting Chungcheongnam-do direct management enterprises. To do this, this research analyzed influence with acceptability of local public enterprise management assessment by composing the area with 5 aspects related to local public enterprise management assessment. More differentiated strategy is required to operate management assessment efficiently, since direct management enterprises have different shape from other public enterprises in respect of organizational structure. In case of water and sewage, it tends to be difficult to return the result of management assessment to the local government organization, so that managers' interest and effort is necessarily required. Also, responsible person's professionalism is required to raise achievement of direct management enterprise through management assessment, politic management plan for this is necessary. Above all, the structure of incentive for management assessment result is difficult in making intended effect as other public enterprises. Therefore, differentiation of compensation system for assessment result is required.

In America, where obesity rate ranks no.1 in the world, the plus size market is rapidly expanding with various American brands adding plus size lines in a way to diversify their products. As obesity is expanding throughout the younger generation, the necessity to develop products according to different characteristics of body shape that can fulfill the needs of young plus size consumers is being emphasized. In this study of young plus size, our focus is on providing wider spectrum of design choices for consumers by analyzing different body shapes, categorizing them, and then identifying the differences of design among them. More specifically, the object of this study is to analyze the elements that differentiate the designs from each other by virtually trying out the same item on avatars of various body shapes. Thus, we can identify the elements that needs to be differentiated according to different body shapes after implementing virtual fitting program on plus size shapes that are rather difficult considering the reality of domestic fashion companies. In this way, we are able to provide fundamental data for American plus size fashion market and design development for Korean fashion companies that are under way of entering or planning to enter the American market. Furthermore, this will demonstrate the actual details of the designs that will eventually help the development of specialized product for the globalization of Korean fashion industry.

Korea Microlensing Telescope Network (KMTNet) is one of powerful tools for investigating primordial objects in the inner solar system in that it covers a large area of the sky ($2{\times}2$ degree2) with a high observational cadence. The Deep Ecliptic Patrol of the Southern sky (DEEP-South) survey has been scanning the southern sky using KMTNet for non-bulge time (45 full nights per year) [1] since 2015 for examining color, albedo, rotation, and shape of the solar system bodies. Since 2017 January, we have launched a new collaborative group between Korea Astronomy and Space Science Institute (KASI) and Seoul National University (SNU) with support from KASI to reinforce mutual collaboration among these institutes and further to enhance human resources development by utilizing the KMTNet/DEEP-South data. In particular, we focus on the detection of comets and asteroids spontaneously scanned in the DEEP-South for (1) investigating the secular changes in comet's activities and (2) analyzing precovery and recovery images of objects in the NASA's NEOWISE survey region. In this presentation, we will describe our scientific objectives and current status on using KMTNet data, which includes updating the accuracy of the world coordinate system (WCS) information, finding algorithm of solar system bodies in the image, and doing non-sidereal photometry.

A cleaning blade is an attachment installed in the toner cartridge of a laser printer for removing the residual toner from an organic photo-conductive drum. There have been many studies on the performance and life of the rubber blade. We focus on optimally designing the blade shape parameters to minimize the maximum stress of the blade while satisfying design constraints on the cleaning performance and part interference. The blade is optimally designed using a design of experiments, meta-models and an optimization algorithm implemented in PIAnO (process integration, automation, and optimization), a commercial PIDO (process integration and design optimization) tool. We integrate the CAE tools necessary for the structural analysis of the cleaning blade, automate the analysis procedure, and optimize the solution using PIAnO. We decreased the maximum stress by 32.6% in comparison with that of the initial design.

Dynamic aeroelastic behavior of structurally nonlinear Joined Wings is presented. Three configurations, two characterized by a different location of the joint and one presenting a direct connection between the two wings (SensorCraft-like layout) are investigated. The snap-divergence is studied from a dynamic perspective in order to assess the real response of the configuration. The investigations also focus on the flutter occurrence (critical state) and postcritical phenomena. Limit Cycle Oscillations (LCOs) are observed, possibly followed by a loss of periodicity of the solution as speed is further increased. In some cases, it is also possible to ascertain the presence of period doubling (flip-) bifurcations. Differences between flutter (Hopf's bifurcation) speed evaluated with linear and nonlinear analyses are discussed in depth in order to understand if a linear (and thus computationally less intense) representation provides an acceptable estimate of the instability properties. Both frequency- and time-domain approaches are compared. Moreover, aerodynamic solvers based on the potential flow are critically examined. In particular, it is assessed in what measure more sophisticated aerodynamic and interface models impact the aeroelastic predictions. When the use of the tools gives different results, a physical interpretation of the leading mechanism generating the mismatch is provided. In particular, for PrandtlPlane-like configurations the aeroelastic response is very sensitive to the wake's shape. As a consequence, it is suggested that a more sophisticate modeling of the wake positively impacts the reliability of aerodynamic and aeroelastic analysis. For SensorCraft-like configurations some LCOs are characterized by a non-synchronous motion of the inner and outer portion of the lower wing: the wing's tip exhibits a small oscillation during the descending or ascending phase, whereas the mid-span station describes a sinusoidal-like trajectory in the time-domain.

Clothes enhance visual images through the interaction between space and background of the wearer. The influence of background is important as that of the clothes when the observer understands the images. We look at fashion pictures used as important as that various backgrounds are presented depending on the image of the clothes. The clothing the model wears in the pictures takes on shape and space which supports the clothes. The background interact to from the whole image. The background has an important influence on the delivery of image for the clothes. However when the clothes are presented in the background there are some cases that all or parts of clothes can be shown. We must consider the composition ratio of the clothes and background which influences the whole image of the clothing. These interactions and influences on the whole image in regards to clothing background and the ratio will be the focus of this study. clothing was Modern Mannish Casual, Feminine, Ground was decided artificial setting 1 natural setting 1, indoor setting 1, artificial setting 2, natural setting 2, indoor setting 2, Percentage of Clothing was 80% , 140%, 200%,.

Importance of appearance as a means of self-expression and communication is increasing in modern society even for men. And appearance has become an significant factor affecting men's quality of life. The main objectives of this study were to develop an instrument measuring appearance related quality of life(ARQoL), and examine the body factors influencing ARQoL. The ARQoL instrument was developed from in-depth interviews, focus group interviews, and literature review, and were revised through two pre-tests. The final questionnaire was administered through on-line survey with 440 men. Quota sampling was used based on age and body size. The results indicated that high ARQoL group showed significantly higher satisfaction on body factors including face, weight, shape, body proportion, hair, and overall impression than low ARQoL group. There was no significant difference in terms of satisfaction on height between two groups. Factor analysis showed that ARQoL consists of four factors - physical, economic, psychological and social factors. Overall impression was the most important body factor affecting all four factors of ARQoL and has very strong influence especially on economic ARQoL. BMI was also a significant factor affecting physical, economic and social ARQoL except psychological factor of ARQoL. Face had significant influence only on economic and psychological aspects of ARQoL.

Opposed to following the contours of the human body, the voluminous enlargement in costume, which characterizes the distinguished enlargement in space rather than the contour of human body, mean the enlargement aspect involving the vertical protrusion and the expansion of shape and volume as well as the extension of length. The costume enlargement as a different method of expression is a symbol showing a meaning of something and an aesthetic expression containing man's will. This voluminous enlargement of costume, as an aesthetic expression, has different formative characteristicsand immanent meanings according to ideals and thoughts as well as social and cultural background of each age Accordingly, the aesthetic consciousness also differaccording to the change of the times. To study the aesthetic consciousness of costume's voluminous enlargement, focous had been given to milieus that show comparatively conspicuous voluminous enlargement Periods that have been subjected to this study include costumes of the ancient Egypt, the Gothic period in the Middle age, the Renaissance, the Baroque Rococo of the recent times, and the modern era (Empire, Romantic, Art Nouveau. etc) With focus given to the principle of design obtained through this study were used to analyze the aesthetic characteristics, Futhermore, based on the spirit of the times and the socio-cultural symbolism, research on immanent meanings, as supported by objectivity and universal validity, was also made, the enlargement beauty of costume had been placed under the aesthetic category and, by interpreting the analogies of presented in aesthetic consciousness, the true nature of the voluminous enlargement in costume had been traced. To Conclude, the aesthetic consciousness of the voluminous enlargement of the costumes in history was found to have following characteristics: (l) Metaphorical (2) Unlooked-for irregularity (3) feeling of satisfaction driven by self-enlargement (4) Dignified sublimity (5) Symbol of wealth and class (6) Ceremonial dignity (7) Tradition of the nobility (8) Aesthetic ornament (9) Ideal contour of the body
