The issues of generation, delivery, and processing of information which have been treated importantly in information design field have evolved along with the evolution of the humankind. In the modern society, the vast amount of, complex, and artificial forms of information such as big-data is accounted for the majority and claims of interest focusing on how to effectively design those kinds of information are being increased. This study explored the visualization methods applied with the natural objects as motives as one of the ways for users to easily get their perception and cognition to the information. Nature has long influenced on the human figural activities. The natural objects take the optimum visual shapes and provide the diverse inspiration and emotion to the designers in the various design fields such as product design, architecture design, and so on. Through the literature studies, we suggested the compositional principles of natural objects and the principles for observing and analysing natural objects as a principle to use the natural objects for information design domain. We, also, suggested the information design approach model which is inspired the natural objects by linking those two kinds of principles to the information design's visual realization factors and explored the possibilities of utilizing of the approach model by the case studies.

The purpose of this paper is to present the direction of emotional lighting design of a new concept suitable for the user's living environment based on the experiment and the result of the recognition of the cognitive effect of the color of the lighting on the user's sensibility. As a research method, we collected meaningful results of color temperature and emotion of light through literature research and experimented with users in their twenties. Based on this, we presented the design direction of emotional lighting. As a result, we designed emotional lighting that can transform the shape of the four joints freely to realize the user's demand. We also derive the color temperature of light that can be optimized for the user's work and environment, Concentration, mood, and relaxation. The result of this paper is meaningful and worthy of suggesting emotional lighting design with user - oriented new perspective, deviating from previous method of planning lighting.

This study was to identify HCl design factors for increasing information processing and attention for mentally retarded children. Several factors such as size, location, moving distance were varied for three experiments operated by the amount of information. The results showed that the larger size of target, the greater moving distance of target, and the less amount of information increased mentally retarded children's sensitivity. Also, when the target was displayed at upper left of computer screen, sensitivity of mentally retarded children was high, compared other locations of screen.

건물의 평면 디자인이나 도로의 디자인과 같은, 보행자를 고려해야 하는 디자인 혹은 그와 유사한 문제의 최적화를 위해서 군중 시뮬레이션이 필요한 경우가 있다. 이때 보행자 에이전트에 대한 모델이 필요하며 에이전트 디자인을 얼마나 신중하게 하느냐가 군중시뮬레이션의 결과에 많은 영향을 미친다. 기존의 보행자 모델은 에이전트로 하여금 이성적 행동을 하도록 하는 데에 초점이 맞추어져 있었다. 하지만 사람은 심리경향을 갖고 있으며, 이를 고려한 보행자 모델은 좀 더 현실과 가까운 군중 시뮬레이션이 가능하도록 해 준다. 본 논문에서는 MBTI(Myers-Briggs Type Indicator)의 척도 중 하나인 외향과 내향 척도를 기존의 보행자 모델에 적용시켰다. 외향과 내향을 하나의 변수로 보고 그에 따른 행동 패턴의 결정에 대한 함수를 만들었다. 그리고 이 모델을 사용하여 2 차원의 군중시뮬레이션을 해 보았다. 이 시뮬레이션은 출구를 가지고 있는 평면구조를 사용하여 위급한 상황일 때를 가정하여 에이전트들이 출구로 빠져나가도록 하는 것이다.

In this research it is concentrated first of all on the attempts to reconstruct the historical context of the idea for the space design based on the natural construction and to re-appropriate il critically to the present context. Sequentially in the areas of philosophy, biology, neuroscience, and architecture it has been variously discussed on the problems about the synthesis of biology and techniques. In the context of the consilience of biology and technique Werner Nachtigall, who has intended to shed light on the morphological principles in the natural construction, founded the 'Bionik', which is different from the bionics or the biomechanics that are oriented to the imitation of natural forms. The space design that is on the basis of the Bionik treats organisms as a functional whole. Therefore the Bionik space design follows two kinds of principle such as the principle of analogy and the principle of optimization. After all the understanding of the consilience of nature and technique for Nachtigall and Bionik designers tends toward the explication of the complex process in which the human perceptions, the environment, and the phenomenal techniques are united together, and this complex process is associated with the space design based on the Bionik.

The Sejong City was launched in July 2012 and was initially focused on the relocation of central administrative agencies, but it has been changing from an administrative city to a fourth industrial city since 2019 to a smart city and the implementation of Korea's New Deal in 2020. Identity design needs to be reevaluated accordingly. In particular, the web environment is also calling for an optimized identity design due to rapid changes in information technology such as various wearables and the Internet of Things. As the number of responsive web sites where information and communication technologies can be developed and optimized screens can be viewed increased, identity was intuitively communicated to users and designs were applied to make them more distinct and empathetic to other cities. Prior to the study, we looked at prior studies on the changing times in the web environment and the reactive web, and analyzed the identity design of the reactive web and applied minimalism characteristics step by step. Based on this, we surveyed experts and non-experts on the proposed survey by applying minimalist characteristics (simple, repeatability, and spatiality) of reactive identity and found that it was easily and intuitively recognizable in a small web environment such as mobile. Therefore, we hope that Sejong City's identity will continue to be studied in various ways and efficient management so that identity can be established in accordance with the changes of the times.

Regardless of the size, the role and meaning of the space required for human daily life are the same. Especially, as the spatial design is small and the size is small, the careful design and problem solving are needed to enable comfortable and convenient life even in a narrow space. The purpose of this study is to design a convergence model that utilizes the advantages of BIM, which can simulate actual design based on a new one-person housing space design plan optimized for one person. This study applied the BIM design technology to one-person housing 2D design, and the suitability examination and the space optimization design of the interior design were carried out. As a result of the study, utility of space improvement, consideration of housing environment, interference check, application of eco-friendly housing system, and MEP design item were derived. Therefore, BIM space design in interior space has been confirmed as a way to overcome limit and inefficiency of 2D design which is applied to actual space by various space design elements. Based on the results of this study, the One-person housing space model, which is applied to the study, is a pure creation designed based on various one-person housing of social and cultural peculiarities derived from previous research. This design example was applied to BIM technology to confirm the detailed and practical design possibility.
