Salk Institute for Biological studies is widely considered as architectural masterpiece of Louis Kahn's. Its iconic plaza with symmetrical concrete structures, overlooking the Pacific ocean in La Jolla, has been acclaimed as a facade to the sky. Little has been written on Kahn's achievements in the building system integration in order to bridge the gap between technology and design. This paper explores the technical issues, the design intents, and the major building systems to identify the Kahn's integration methods between building systems. The project is analysed into four major systems; structure, mechanical, envelope, and interior system. The integration methods of building systems are investigated in physical, visual, and functional aspects. The most distinguished cases of building system integration are the introduction of the interstitial floors between the laboratories and the creation of the smooth and warm materiality of exposed concrete walls. Kahn proposed open floor plans for the laboratories which are capable of easily adapting to changing needs. He also introduced the interstitial floors which are framed of the vierendeel truss systems and deliberately overlapped the structure systems with the mechanical systems such as ducts, water pipes, and electric conduits. The exposed concrete walls mixed with pozzolan ashes look very much like granite or limestone as the result of the physical and visual integration between structure, envelope, and interior systems.

The construction method of scaffolding structures is different from Mortise and Tenon and bucket arch structure of traditional large woodwork. It forms an independent construction system-fixing nodes with knots, a large number of diagonal braces are used to fix shelves and the structures mostly contain X-shape and triangular shape details. Simple ones include stalls, sheds, rain sheds, altars, lamp racks etc. But the scaffolding with larger scale and more complicated structure are modeled on archways, theatres and other buildings which are used in commercial and festival activities. At present, Macao, Hong Kong, Guangdong, Sichuan, Shanxi and other places in China have retained the custom of using scaffolding structures in important festival activities, but their uses, techniques and building types are slightly different from place to place. Due to building and demolishing at any time, the construction and service cycle is short. As a result, there are almost no physical objects left. We can only deduce the use and technical characteristics of ancient scaffolding skills through the colorful building styles that have been preserved with folk activities in various parts of China, the craftsmanship handed down from generation to generation by the scaffolding guild and artisans, and the description of cultural and historical materials and the mutual corroboration of visual materials.

제품에 대한 이미지 표현은 그것의 시각형상(visual image) 구조가 파악되어야 보다 객관적으로 기술할 수 있다. 시각 표현이라는 주관적 문제도 분석을 하지 않고서는 답변될 수 없고, 다루고자 하는 제품의 시각형상 전모가 밝혀져야 그 속에 담긴 디자이너의 사상적 배경도 추론해 낼 수 있는 것이다. 따라서 본 연구는 실내 주방용품 중에서 필립 스탁(Philippe Starck)이 디자인한 '레몬즙 짜개(Lemon Juice Squeezer)'를 대상으로 시각적 표현이 가지는 구조를 분석한 후, 그 제품의 특정 이미지가 어떻게 구성되어 있는지 기술한 것이다. 제품에 담긴 표현이 분석된다는 것은 제품의 구성성분을 밝혀 디자이너와 사용자간에 상호 이해의 폭을 증진시킬 수 있음을 의미한다. 연구방법으로는 햄비치(Hambidge, J) 교수의 'The Elements of Dynamic Symmetry'를 응용한 수리적 모델을 도입하여 레몬즙 짜개 이미지의 부분 내지 전체를 포괄하는 계열체(Paradigm) 분석을 시도하고, 제품공간 내에서 설정되는 범위를 정의해 주는 결합체(Syntagma) 분석을 행한 후, 이를 표기하는 기술은 김복영 교수 의 시각 기호 기술법을 따랐다. 결론적으로 본 연구는 향후 공간과 소품과의 관계, 제품과 사용자와의 관계, 오브제 자체의 조형 비평 내지는 분석이 감성적으로 흐를 수 있는 소지를 경계하는 차원에서, 그 대안으로 제품에 대한 시각형상의 구조와 성분분석을 수리적 모델을 통해 밝히고, 형식과 내용의 관계를 객관적으로 확인할 수 있는 분석예술학 방법을 제시하였다.

시각조사의 일은 대부분 숙련된 조사자에 의해 이루어지므로 시간이 경과 할수록 조사의 질은 감소한다. 그러므로 조사과정의 자동화가 요구되고 있으며, 실용적인 시각조사시스템을 위해서는 실시간에서의 데이터 처리능력, 다양한 입력물체에 대한 유연성 및 저렴한 시설비가 요구된다. 본 논문에서는 이러한 요구에 적합한 조사방법을 제안한다. 기존의 하드웨어 방식과는 달리 소프트웨어에 의해 조사데이터를 처리함으로써 조사시스템을 유연성 있게 하기 위하여 피라미드 데이터구조를 이용한 divide-and-conquer 기술과 간소화된 패턴 매칭방법을 결합한 시각조사 알고리즘을 제시한다. 이 방법에 의해 비교되는 패턴의 데이터 수를 감소시킬 수 있었고, 그 결과 조사속도를 줄일 수 있었다.

A high-efficiency and small-sized switched-mode line transformer (SMLT) is proposed in this study. The conventional structure of an adapter is composed of line transformer and rectifiers. This structure has a limit in miniaturizing due to low-frequency line transformer. Another structure is composed of power factor correction (PFC) and DC/DC converter. This structure has a limit in reducing volume due to two-stage structure. As the proposed SMLT is composed of an LLC resonant converter, a high-frequency transformer can be adopted to achieve isolation standards and size reduction. This proposed structure has different operation modes in accordance with line input voltage to overcome poor line regulation. In addition, the proposed SMLT is applied to the front of a conventional PFC converter, because the SMLT output voltage is restored to rectified sinusoidal wave by using a full-bridge rectifier in the secondary side. The design of the PFC converter is easy, because the SMLT output voltage is controlled as rectified sinusoidal wave. The validity of the proposed converter is proven through a 350 W prototype.

In this paper, we propose an efficient and effective selective protection scheme to SVC that exploit the propagation of protection effect by protecting significant frames that can give the maximum visual quality degradation. We model SVC dependency coding structure as a directed acyclic graph which is characterized with an estimated visual quality value as the attribute at each node. The estimated visual quality is calculated by using our model based on the proportions of intra- and inter-predicted MBs, amounts of residual, and estimated visual quality of reference frames. The proposed selective protection scheme traverses the graph to find optimal protection paths that can give maximum visual quality degradation. Experimental results show that the proposed selective protection scheme reduces the required number of frames to be protected by 46.02% compared to the whole protection scheme and 27.56% compared to the layered protection scheme.

The authors investigate influences of manipulator dynamics on and roles of kinesthetic sensation and visual sensation in a Human-Machine Cooperative System (HMCS). At first, the general structure and essential transfer functions of HMCSs are described based on the previous work. Then, after showing theoretical treatment of manipulator dynamics, this paper analyzes the influences on HMCSs in two cases: one is the control design focusing on tool dynamics and reaction force transfer function, and the other is that specifies maneuver transfer function and transfer function for object dynamics variation. In addition to conventional experiments only employing kinesthetic sensation, other experiments with both kinesthetic and visual sensations are performed to examine difference in the roles of these sensations and the validity of the design without the visual sensation.

The walls of art museums become the background of exhibits, and they form a unit space depending on the of each exhibit. In addition, the walls are configured and presented depending on the rhythm of space, or the structure of an axis. In this study, according to the axis composed for each unit space, the presentation methods of walls were classified as follows: The central type, the skewed type, the crossed type, the one-side corridor type, and the two-way corridor type. By analyzing visual configurations formed by the arrangement of each unit space, the value and the hierarchy of walls are discussed To analyze the classified types with the physical change of unit space, the factors of visual integration, connectivity, depth, and visual axis are compared, and various configurations of walls and space change are applied.

Visual trope is one of the important appealing methods of creativity to induce voluntary consumer participation. In many cases, it delivers a message using metaphors. To define the concepts of_metaphor, we investigated methods of expression and significance of metaphor itself and associated forms; in all: metaphor, analogy, catachresis, metonymy, and synecdoche. We also considered the structure of each form to propose a method of metricizing the metaphor Consequently, we found that the metaphor of a visual trope is a type of operation and development of codes. We suggested models for each form type and concept of metaphor through the evaluation of metaphor significance and case study. Metaphor significance forms mutually close relationships with codes of pragmatics, semantics, and syntax. We suggested a type of metrics or a guideline for an expression method and evaluation of a visual trope appropriate for a metaphor form type. Therefore and importantly, the following study presents unique, but manifold results that are also useful in the field of design.

스마트 미디어의 등장으로 짧고 빠르게 진행되는 영상 콘텐츠가 등장했고 관람의 조건도 산만한 환경과 짧은 시간에 복잡한 외부 상황으로 지각이 분산된 환경에서의 관람으로 변화했다. 이에 따라 스마트 미디어 영상은 인내심이 부족한 시청자의 시선을 잡아두면서 빠르게 의미전달을 어떻게 할 것인가를 고려하는 것이 중요하게 되었다. 작은 화면이라는 제약 과 빠르게 변화하는 이미지 정보는 장편 극영화의 경우와는 다른 지각적 수용과정을 염두에 두어야 하는 것이다. 우리의 시 지각은 받아들일 수 있는 시각적 정보가 한계가 있고 특히 움직이는 영상에서의 인지력은 더 부족하므로 스마트미디어 영상의 연출은 지각적 이해를 높일 수 있는 방식이 관건이 될 수 있다. 시각적 부담을 줄이면서도 이야기하고자 하는 바를 효과적으로 전달할 수 있게 하려면 UI Design에서 말하는 직관성과 행동 유도성을 영상에 적용하여 직관적인 영상 이해를 끌어내는 것도 하나의 방안이다. 클로즈업, 정면성과 3분할의 안정된 구도, 색채 등은 직관적 시각을 유도하는 '시각유도성'의 수단으로 적절하게 활용될 수 있다.
