  • The vulnerability of privacy in the Identity Management System (IMS) is the most pressing concern of ordinary users. Uncertainty about privacy keeps many users away from utilization of IMS. Therefore, this paper proposes an access-control oriented privacy model for IMS. The proposed model protects privacy using access control techniques with privacy policies in a single circle of trust. We address characteristics of the components of for the proposed model and describe access control procedures. After that, we show the architecture of privacy enforcement and XML-based schema for privacy policies.

  • This study analyzes the visage in fashion illustration based on the deconstructed visage of Francis Bacon's paintings as well as analyzes fashion illustration works since 2000. The deconstructed visages in Francis Bacon's paintings are classified as blurring, elimination, distortion and division. The expressive methods and meanings in fashion illustration (according to categorization) are as follow. Blurring shows an ambiguous visage organ by the sweeping of the brush, removal of a boundary among the visage, body and clothes, gradation of organic line like visage shapes, stretching of the a plat combined to visage and fragmentation of visage. It represents an uncertainty of the fashion theme and image interpretation, impossibility of figure by ambiguity, fantastic effect and the induction of the uncanny. Elimination shows the background color's painting of a photo-montage, overlap of a cutting of visage's part and background of a plat, elimination of the visage and the elimination of eyes, nose or lips. It represents a weakened identity, the reinforcement of anonymity, creation of a violent image, and uncanny unfamiliarity. Distortion shows a distorted visage by free drawing, and unconscious drawing line, fluid digital body, combination of an unconscious curve, and an eccentric combination of the accidental. It represents the relief of specialty about realistic existence, hypothetical immateriality and fantasy. Division shows overlapped visages with different angles, the weird combination of a plural visage and different species and a plural breakaway of direction, and the position of several organs. It represents motion by power's trace, non-territory of species, ambiguity and uncertainty and the uncanny.

  • The damped least-squares inversion has become a most popular method in finding the solution in geophysical problems. Generally, the least-squares inversion is to minimize the object function which consists of data misfits and model constraints. Although both the data misfit and the model constraint take an important part in the least-squares inversion, most of the studies are concentrated on what kind of model constraint is imposed and how to select an optimum regularization parameter. Despite that each datum is recommended to be weighted according to its uncertainty or error in the data acquisition, the uncertainty is usually not available. Thus, the data weighting matrix is inevitably regarded as the identity matrix in the inversion. We present a new inversion scheme, in which the data weighting matrix is automatically obtained from the analysis of the data resolution matrix and its spread function. This approach, named 'extended active constraint balancing (EACB)', assigns a great weighting on the datum having a high resolution and vice versa. We demonstrate that by applying EACB to a two-dimensional resistivity tomography problem, the EACB approach helps to enhance both the resolution and the stability of the inversion process.

  • Analysis of runoff is substantial for effective water management in the watershed. Runoff occurs by reaction of a watershed to the rainfall and has non-linearity and uncertainty due to the complex relation of weather and watershed factors. ANN (Artificial Neural Network), which learns from the data, is one of the machine learning technique known as a proper model to interpret non-linear data. The performance of ANN is affected by the ANN's structure, the number of hidden layer nodes, learning rate, and activation function. Especially, the activation function has a role to deliver the information entered and decides the way of making output. Therefore, It is important to apply appropriate activation functions according to the problem to solve. In this paper, ANN models were constructed to estimate runoff with different activation functions and each model was compared and evaluated. Sigmoid, Hyperbolic tangent, ReLU (Rectified Linear Unit), ELU (Exponential Linear Unit) functions were applied to the hidden layer, and Identity, ReLU, Softplus functions applied to the output layer. The statistical parameters including coefficient of determination, NSE (Nash and Sutcliffe Efficiency), NSEln (modified NSE), and PBIAS (Percent BIAS) were utilized to evaluate the ANN models. From the result, applications of Hyperbolic tangent function and ELU function to the hidden layer and Identity function to the output layer show competent performance rather than other functions which demonstrated the function selection in the ANN structure can affect the performance of ANN.

  • As a period of pluralism, today's museum architecture has been expanding social and cultural meaning. So, Various expressions are appearing in museum architecture. Accordingly, the museum must be very reproducible and comply with aesthetic requirements. At the same time, museum construction in urban design and features must satisfy professional requirements. SANAA is one of contemporary architects has been decisively deleted existing fixed and functional layout type of program through 'The new hierarchy'. Thus, the experience of the space will vary. Now, museum space is urgently needed than ever before crustal movements. Thus, this study aims to contribute an alternative to the museum space configuration according to the trend of the times through 'The new hierarchy' of SANAA. This paper is limited to the cases of the SANAA's museum architecture. We analyze the characteristics of representation on 'The new hierarchy' appear in the museum space configuration and then, examine the value of the spatial. SANAA's 'New Hierarchy' is going to set the cognitive boundary by expression targeting plane and the surface. It is completely different than the previous boundaries. Characteristics of the expression represents non-centrality, decentrally, non-oriented, uncertainty, non-territorialization, uniformity. It is steady that identity of Space, Human, Environment in Museum. They have a relationship each concept of Independence, autonomy, equality.

  • This paper treats with transitional development of medico-hygienical situation in district Yanbian along with the evolution in specific field of medicine. This work is particularly important in shaping TKM identity as TCM embraces Chao medicine asserting it as one included in TCM. This research deals with themes of migration of Chao minorities to this territory and their medico-hygienical situation. Lifted bans on immigration in late Qing dynasty with uncertainty of Korea(Chosun) triggered the immigration to this district. The flow was heavily strengthened under the influence of Westerners and Japanese imperialism into china which consequently provoked the ruin of Qing dynasty, the civil war between republicans and communist and the socio-political changes in Korea. As population growths, the establishment of hospitals and immigration of healthcare professionals were also increased. Though this district is located in Chinese mainland the influence of Japanese was also relevant which lead to medical practice reflection both sides. Mutual combination and influence of western(contemporary) medicine, TCM and TKM practices made the particularity of chao medicine.

  • The world is suffered from severe environmental problems such as climate change and global warming due to radical industrialization after the Industrial Revolution. With advancement of science and information technologies, national borders have become meaningless. In this global trend, movable exhibition shall be supposed to pursue "Local in Global." Thus, movable exhibition should get involved in an effort to find a cultural identity in the globalization and to better our position among the various cultures. As an alternative, movable exhibition can be established by combining biomimicry, which is biomimicry of life by imitating biological system, with Flexibility of movable space. By providing a hint to environmental problems and cultural uncertainty, this alternative will generate an advanced exhibition trend that is more environmental-friendly and more efficient. As a cumulative concept created by the nature for 3.8 billion years, biomimicry has evolved a lot more than the modern science. By catching this point, "A study on flexibility of movable exhibition through biomimicry notion" is providing a revolutionary paradigm stepping beyond the current exhibition trend, which pursues coexistence of human beings and the nature and, at the same time, introduces our culture.

  • This study uses a macro-viewpoint to investigate how female world leaders' clothing behaviors are different by nation and culture. This study conducted a comparative study on clothing behavior by cultural block in order to understand similarities and differences based on Hofstede's cultural dimensions theory. The findings are as follows. First, the clothing styles of female world leaders are categorized into classical suit style, national traditional style, and eclectic style. Second, classic suit style is more often found in countries characterized by high individualism, low power distance index, and low avoidance index. The style represents individual activity and rationality as well as trust towards women acting in men's roles. Third, a national traditional style is found in countries featuring high collectivism, high power distance index, and high uncertainty avoidance index. These countries share a culture that emphasizes harmony with the whole, rather than any one given part; consequently, clothing style represents a national identity (or the roles as a national member) rather than that of the individual level. Fourth, an eclectic clothing style is expressed in a mixture of classical suits and a national traditional style that depends on how much Eastern and Western cultures are reasonably compromised or Eastern tradition and Western culture coexist.

  • The purpose of this study is to investigate the symbolic meaning in body image and fashion style portrayed in Korea and American movies in aspects of sex, race, nature, and technology. The researcher analyzed movies in Korea and USA, and the results were as follows. In aspects of sex, movies portrayed new masculinity and femininity escaped from previous gender stereotypes, and the clothing styles characterized sex identity and sex roles. In aspects of race, more various races appeared in America movies than Korea's, and the appearance and stereotypes related with race were blurred by the globalization and the change of film market environments. In aspects of nature, Korea movie portrayed the human being as lyrical appearance in nature, and America movie expressed the human as a strong men conquering the nature in adventure movie or super human image combined with nature thing which endowed nature's superior characteristics to human body in fantasy and science fiction movies. In aspects of technology, the human bodies were described as cyborg, alien, or super human, which symbolized the do-identification in digital world, de-boundarization between human and machines, and the human's uncertainty.
