In architecture, Sensibility is the most basic thing in the environmental cognition. Emotion is the phychological or cognitive phenomenon of sensory changes. A cross-causal relationship is formed between the two, and they have a consensus in contact with humans and environment. Sensibility ever to serve as bundle and cognize as mutual superposition. Humans unconsciously perceive through the synesthesia that integrated all the senses. In this study, it has been identified as a result of the study, the architectural design through the sense must be design to the multisensory experience of the emotional design. Depending on the times change, it can know that the gradual changes based on the anthropocentric sense and sensibility. Emotional design in architecture shall ensure that a variety of experience through the multisensory. In this emotional design, multisensory design (or various sensory function) -visual & tactory or visual & auditory etc.- is required beyond the limitation of conventional visual concenturated. Therefore, In order to achieve the demands of the modern social objectives of sympathy or empathy for the human-centered design sensibility, the visual perception as well as a variety of sensory must be recognized that a combination of cognitive and functional. And the application of multisensory design is required to aim the synesthesia cognition.

The layer technique is to produce many memorable scenes by generating layers of new experiences on the existing ones as it is adding the cognitive layers on to the visually seen landscape. Its need is high for places whose landscape itself influences perception, value or expression and which determines the spatial and quality standards. The existing floor plan-based design methods have failed to be useful in generating complex visual experiences. In order to maximize the aesthetical landscape experiences in landscape planning, cognitive layers are needed which complement the input of adequate cognitive elements and the inter-element relationships. Here, layers are utilized to change the arrangement of the landscape elements and coordinate the cognitive flow so that the images could be connected and imagination could occur. A case in point is Anhyun Village in Gochang where physically distinctive layers are additionally set to make a visual experience enriching. The new landscape layers discover the fact that it provides diversity in experiencing the village landscape and forming the sense of beauty and that it is deeply immersed into the daily life of the village. Meanwhile, Guwau Village in Taebaek is an example showing the usefulness of various-layer setting in landscape planning in setting effective circulation planning. That is, the bottom line is the spacing-starting where and making it stay where for a few seconds, and the visual layers. It is also critical to encourage inducing circulation so that layers of the senses stimulating five senses could intervene. Lastly, Mulgeon-ri in Namhae is a case which directly made a parallel of the physical layers of the landscape composition and the cognitive layers of the landscape experience. Artificial landscape planning is mostly about manipulating of visual traits that people feel beautiful, but the layer technique is linked to how to make experiences enriching and renewed.

This paper proposes architecture of a cognitive radio engine platform and the allowable frequency channel reasoning method that enables acquisition of the allowable channels for the military tactical network environment. The current military tactical wireless communication system is increasing need to secure a supplementary radio frequency to ensure that multiple wireless networks for different military wireless devices coexist, so that tactical wireless communication between the same or different systems can be operated effectively. This paper presents the allowable frequency channel reasoning method based on cognitive radio engine for realizing DSA(Dynamic Spectrum Access) as an optimal available frequency channel. To this end, a case-based allowable frequency channel reasoning method for cognitive radio devices is proposed through modeling of primary user's traffic status and calculation of channel occupancy probability. Also through the simulation of the performance analysis, changing rate of collision probability between the primary users' occupancy channel and the available channel acquisition information that can be used by the cognitive radio device was analysed.

Radio frequency (RF) subsampling can be used by radio receivers to directly down-convert and digitize RF signals. A goal of a cognitive radio/software defined ratio (CR/SDR) receiver design is to place the analog-to-digital converter (ADC) as near the antenna as possible. Based on this, a band-pass sampling (BPS) frontend for CR/SDR is proposed and verified. We present a receiver architecture based second-order BPS and signal processing techniques for a digital RF frontend. This paper is focused on the benefits of the second-order BPS architecture in spectrum sensing over a wide frequency band range and in multiband receiving without modification of the RF hardware. Methods to manipulate the spectra are described, and reconstruction filter designs are provided. On the basis of this concept, second-order BPS frontends for CR/SDR systems are designed and verified using a hardware platform.

The purpose of this study is to understand underlying principle to form the U-type folk house in the northwestern part of Kangwha Island by viewpoint of inner residents. It is found that many factors other than climate are coincidentally affecting the shape of house; Resident's fixed thought like following geomancer' suggestion, seeking fortune, and locating house enclosed low site; Economic reason of uniting one house with two buildings and making small type by used timber from dismantled house; Centralizing life with small courtyard by reason of family type change from extended to nuclear; Influence from L or ㅁ type of upper class building at Seoul area. The method is thick description of culture with ethnographic method from cognitive anthropology: Observing the form and restoring residents' life with open-ended deep interview.

This study intends to analyze the relationships between images of arboreta or botanical gardens and the policy supports related to carrying capacity. For this purpose, a questionnaire survey was distributed to 723 public sites nationwide. The results consisting of an exploratory factor analysis, a confirmatory factor analysis, a correlation analysis, and a structural equation method showed that the images of the arboretum or botanical gardens contained 3 factors: cognitive, affective and shape factors. The cognitive factors greatly affected the policy support related to carrying capacity. The policymakers of the arboretum or botanical gardens can consider cognitive elements of images as important aspects in the planning and management factors to improve the support of visitors related to the policies of carrying capacity for sustainable use.

Cultural-historical places, due to their strong symbolic sense of place shared in various people, have important impacts on people's cognitive and emotional reactions. Especially, the visual characteristics of surrounding areas of cultural -historical places directly influence the way the places are perceived, because they function as a visual background of the places. This study examined how the visual characteristics of surrounding landscape of cultural-historical places nfluenced the perception of the places. The visual characteristics of the surrounding landscape was minipulated by a computer simulation in the two aspects; quality and scale. The quality of the simulated landscape was divided by two kinds : natural and artificial . The scale of the simulated landscape was classified by three kinds : 1/3 of the middle ground, 2/3, and 3/3. Specifically, in each photo simulation, simulated natural or artificial background was introduced up to 1/3, 2/3 or the full height of historic monument. After a computer simulation, people's cognitive and emotional reactions to the simulated slides were investigated. The results showed that the quality of surrounding landscape have a great impact on all the cognitive and emotional reactions investigated. On the vontrary, the scale of surrounding landscape was found to habve an impact on partial reactions, such as all the emotions, part of the cognitions, and visiting preference only. The results revealed that the visual characteristics of surrounding landscape should be considered as the crucial elements in planning of cultural-historical places. Based on the study results, several suggestions were made for the landscape planning and conservation for cultural-historical places and historic cities.

This study intends to analyze the characteristics of imageability elements of the tourism space using the spatial cognitive mapping method. For this purpose, this study selects Nami Island as a study site and collects spatial cognitive maps or sketches of the study area focused on tourists in their 20s and 30s after they visit the site. The results of frequency analysis on imageability elements of Nami Island show that paths, landmarks, and edges are more frequently cognized to tourists in their 20s and 30s than districts and nodes. This study determines a new imageability element of the tourism space, "moving objects," such as or bikes or animals. Tourism planners or landscape designers can consider these useful imageability elements as important planning factors in order to improve and clarify the images of tourism spaces.

The first attempt in architectural design theory to consider the perceptual and metaphysical dimension separately with a fully modern scientific manner, which exist in contrast to the Renaissance idea, was Claude Perrault, who emphasized the cognitive factors as an important scientific human issue in building design in 1683 in his book "Ordonnance". Even today many elaborated works to reveal the mysterious design processes based on a set of rational approaches have been introduced since the Design Method movement in 1960's. Their pioneering and challenging efforts to rationalize design process have been mostly rely on the cultural issues whether it takes a qualitative or quantitative stance. On the other hand, however, today's computer generated free form architecture seems not to be aware of those lessons learned from the past and, therefore, this study conducted an extensive research through exploring on morphological building forms with cultural issues to fill up the missing and/or lacking characteristics of today trend in building design.

Nowadays, with progresses in robotic science, the design and implementation of a mechanism for human-robot interaction with a low workload is inevitable. One notable challenge in this field is the interaction between a single human and a group of robots. Therefore, we propose a new comprehensive framework for single-human multiple-robot remote interaction that can form an efficient intelligent adaptive interaction (IAI). Our interaction system can thoroughly adapt itself to changes in interaction context and user states. Some advantages of our devised IAI framework are lower workload, higher level of situation awareness, and efficient interaction. In this paper, we introduce a new IAI architecture as our comprehensive mechanism. In order to practically examine the architecture, we implemented our proposed IAI to control a group of unmanned aerial vehicles (UAVs) under different scenarios. The results show that our devised IAI framework can effectively reduce human workload and the level of situation awareness, and concurrently foster the mission completion percentage of the UAVs.
