As architecture is designed for humans to live in based on practicality, what one experiences within such spaces is important. Such experiences are not felt only by appreciating the structure's appearance, but involve physical presence inside the space and the deepening of the individuals relationship with the space through the body's sensory perception. However, in modern times there is a much greater tendency to rely on superficial experiences by way of images or tastes rather than more meaningful human participation, while the standardization of the object universe is gradually erasing the uniqueness of experience. In light of this, the restoration of emotional and sensory spatial experiences through the design of sensory spaces can be regarded as an important task in modern spatial design. This study contemplated the meaning of emotional spatial experiences through a phenomenological understanding of such experiences, and analyzed the meaning and main factors in the creation of spatial atmosphere as a phenomenon of spatial experience. In addition, we highlighted the fact that spatial atmosphere can be applied as space design methodology by devising methods of expression through an analysis of actual examples. O.F. Bollnow's space theory and the spatial design of Peter Zumthor were the subjects of this analysis. The spatial atmosphere analyzed using Bullnow's theory is a phenomenon in which both the human and space are connected and the ensuing spatial experience embodies the emotions of both. This spatial atmosphere can be understood as a condition in which the human and space are fused together. Furthermore, coincidental/accidental meeting, mediums using potential objects, reorganization of the center due to autonomous boundaries, as well as the three temporalities were identified as the main factors in the creation of spatial atmosphere. Based on this analysis, through the identification of methods of expression for spatial atmosphere in Zumthor's spaces.

Power control is widely used to reduce co-channel interference in wireless networks and guarantee the signal-to-interference plus noise ratio (SINR) of ongoing connections. This technique is also effective for wireless body area networks (WBANs). Although achieving satisfactory SINR is important for WBAN users, they may not be willing to achieve it at arbitrarily high power levels since power is a scarce resource in WBANs. Besides, for WBANs with different purposes, the QoS requirements and concern about the power consumption may be different. This motivates us to formulate the power control problem using the concepts from microeconomics and game theory. In this paper, the QoS objective is viewed as a utility function, which represents the degree of user satisfaction, while the power consumption is viewed as a cost function. The power control problem consequently becomes a non-cooperative multiplayer game, in which each player tries to maximize its net utility, i.e., the utility minus the cost. Within this framework, we investigate the Nash equilibrium existence and uniqueness in the game and derive the best response solution to reach the Nash equilibrium. To obtain the optimal transmission power in a distributed way, we further propose a utility-based and QoS-aware power control algorithm (UQoS-PCA). Tunable cost coefficient in UQoS-PCA enables this scheme to be flexible to satisfy diverse service requirements. Simulation results show the convergence and effectiveness of the proposed scheme as well as improvements over existing algorithm.

본 연구는 경제지리학의 인식론적 접근방법과 지역을 기반으로 연구를 전개하는 지리학의 존재론에서 그 접근방법을 살펴보고, 이를 바탕으로 우리나라 경제지리학의 체계화를 시도하는 것을 목적으로 한다. 1956년부터 시작된 한국의 경제지리학 연구는 그 동안 학문의 독자성이나 연구 접근방법의 체계화에 대한 논의가 없이 선진국 학문의 발달 속에서 이루어져 왔다고 할 수 있다. 그래서 접근방법의 체계화를 위한 인식론과 존재론의 축을 기준으로 신고전경제파, 지리적 정치경제파, 지역구조파, 지방자치단체 경제파로 나누어 체계화를 구축했다. 이러한 경제지리학의 체계화에 경제활동의 주요 이론인 세계시스템론이나 조절이론, 네트워크론, 제도주의 등도 내적으로 포섭해 가면서 지적 변화를 추구해 나아가야 할 것이다.

The contents of this study are as follows. First, an academic understanding has been achieved by exploring the theoretical concept "allegory", and a new theoretical approached methodology has been sought. Second, an analysis-index of fashion illustration cases has been suggested based on the allegory theory of Craig Owens. Third, in order to draw the characteristics of fashion illustration as viewed from the allegorical viewpoint and find out its feasibility, the case studies has been referred and the internal significance, external significance that combines different characteristics has been extracted. In regards to this study method, literature studies and case studies has been done in parallel with each other. This study was done in the following sequence: the establishment of the study system, the drawing of the allegory-associated concepts and the discovering the characteristics of aesthetic expressions. The results of this study on the expression characteristics of fashion illustration as viewed from the allegorical viewpoint of Craig Owens are as follows. First, the borrowing of image, which is a characteristic of allegory, contains the meaning of uncertainty in the fashion illustration as it expresses the image-synthesis and forms a completely different meaning as the fixed meaning is dissolved and it is utilized as a photo-montage technique. Second, the inference of pictogram is the mixture of linguistic medium and visual medium. Fashion illustration utilizes the characters and transmits the fashion information visually and immanently. It has the characteristic of making the information into pictograms and the internal significances of mutual-text with communication function. Third, the uniqueness of location in the fashion illustration has the special nature of utilized mediums as it is used for advertising or publicizing. The fashion illustration from the viewpoint of allegory has the impermanency of existing only for a limited time and reflects the coincidence that gives the meaning of utilized location according to the season trend. Fourth, the cross-breeding is expressed as the mixture of various materials in the fashion illustration. The expressions made by the mixture of media, such as the use of computer graphic programs mixed together with various materials showed the trend of diversity and genre dissolution.

This study examines the characteristics of Paul Smith's fashion from the viewpoint of Habitus. To this end, on the theory of Bourdieu's Habitus concept and theory of the field, we derive the attributes of fashion and fashion designers and Habitus that appeared in fashion from the viewpoint of Habitus. Based on this, the tendency of Paul Smith's Habitus tendency has been examined and how it is expressed in fashion design and store production has been investigated. The scope of the study is from 1977 to the present, and it covers Paul Smith's menswear and stores. Research methods are literature research and visual data analysis. The results of the study are as follows. The characteristics of Habitus' tendency in Paul Smith are childlike imagination and humor, vigorous curiosity and observation, paranoid collection and memos, and British tradition and craftsmanship. Paul Smith's Habitus propensity reflects the following features in fashion design and store direction. First, a unique mix of wit or list structure, second, respect for uniqueness and discrimination with respect for the local image, and third, the new male image was presented to contribute to the diversification of consumers, and fourth, sensitivity and emotion reflecting his Habitus propensity. It is a friendly space for communication. As a result of analyzing and applying to Paul Smith, it was found that the special Habitus characteristics possessed by designers in fashion are important and impart a great influence.

The Attention Restoration Theory (ART) developed by Kaplan and Kaplan proposes that effortful directed attention required in normal life can be fatigued. Restoration can occur in a setting that has restorative qualities. The restorative quality described by the ART involves four concepts: being away, fascination extent, and compatibility. The purpose of this study was to investigate how the restorative quality of landscape influenced the preferences and satisfaction of visitors to an heritage landscape. Four kinds of heritage landscapes of Kyongju were used as environmental surrogates and 150 americans participated in the study. Hartig et al.'s Revised Perceived Restorativeness Scale (RPRS) was used as the psychological measure for the restorative quality, along with other measurement constructs such as cultural uniqueness and novelty. The results showed that RPRS was a reliable measurement tool for assessing the restorative quality of artificial landscapes. Factor analysis identified three valid factors: escape-fascination compatibility, anti-extent. Among the three factors, only two, escape-fascination and compatibility, were found to have important effects on visiting preference and satisfaction. Specifically, higher levels of preference and satisfaction were associated with higher levels of escape-fascination and compatibility. The results indicate that the restorative quality has a high possibility to be used as a frame of reference for assessing various types of landscapes, from natural to artificial. It was also proposed that restorative quality could better explain the experience of the landscape strongly related to specific purpose or motivation.

In this study the meaning of well-being and welfare of home has been analyzed and a new direction in which home economics should advance has been suggested, This study not only would help the characteristics of home economics be properly understood and its displinary position take its own place but also a conceptual analysis which might be uncommon in the studies of learned circles of Korean home economics would be a basis for establishing the uniqueness of the discipline named by home economics. Based on the critical theory of Habermas it has been demonstrated that well-being and welfare of home have been emphasized unfairly in the physical and technical aspects and such a partial pursuit of positivism and purposive rationality of scientific technology has resulted in the situation that home would be gradually encroached and controlled by the social system pursuing purposive rationality. As an alternative to overcome this kind of problems communicative rationality that has em hasis on the process of intersubjective understanding and agreement has been focused. The meaning of well-being and welfare of home has been established through the classification of family life actions in to technical action practical action and emancipatory action, And the characteristics of them have been examined and ideal directionns of each element have been discussed.

탄소나노튜브는 기계적 성질이 매우 뛰어나기 때문에 앞으로 많이 이용될 수 있는 신소재이지만 작은 크기와 특별한 성질 때문에 해석에 어려움이 있으며, 분자 동역학이나 범함수 이론을 이용한 전자시뮬레이션은 계산이 어렵고 시간이 오래 걸리는 단점이 있다. 이러한 단점을 극복하기 위하여 원자 사이에 작용하는 힘을 구조 부재로 치환하는 방법을 사용할 수 있다. 본 연구에서는 0.1nm 길이의 탄성 보를 사용하여 나노튜브를 구성하는 원자 사이의 힘을 묘사하고 선형 압축거동을 해석하였다. 선형 거동은 기존의 다른 방법을 사용한 결과와 잘 일치하였으며, 보 요소의 특성이 적절하게 정해질 경우 비선형 거동의 연구에도 이용될 수 있을 것이다.
