With recent advances in wireless communication and low-power miniaturized biomedical sensor and semiconductor technologies, wireless body area networks (WBAN) has become an integral part of the disaster aid system. Wearable vital sign sensors can track patients' status and location, thus enhancing disaster rescue efficiency. In the past few years, most of the literatures in the area of disaster aid system based on WBAN have focused on issues concerning wireless sensor design, sensor miniaturization, energy efficiency and communication protocols. In this paper, we will give an overview of disaster aid, discuss about the types of network communication as well as outline related issues. We will emphasize on analyzing six key issues in employing the disaster aid system. Finally, we will also highlight some of the challenges that still need to be addressed in the future in order to help the disaster aid system be truly and widely accepted by the public.

Designed by star architect of Moshes Safdie, Raffles City Chongqing includes a total of 6 mega high-rise towers 250 to 380 m tall, a sky conservatory, a 5-storey high shopping mall and a 3-storey basement car parking. Located at the confluence of the Yangtze and Jailing Rivers, the site for the project is imbued with a significance that is immediately symbolic, both as a sign of Chongqing's important past and as a vivid indicator of the city's thriving present and future. The design for the project to be situated at this gateway takes as its governing idea the image of powerful sails upon the water. The outer facades of the project's eight towers - the transparent surfaces that will face the water to the north - are meant to recall a fleet of ancient Chinese ships, with their huge rectangles of white canvas filled by the wind. This is a $1.13million\;m^2$ mega scale integrated project of office, retail, hotel, service residence and high-end residence with the transportation hub and traffic circulation at various levels of the project. This paper presents the multi-dimensional hybrid design, engineering and construction of this mega scale project. The innovations and the cutting-edge technology used in this project are introduced and discussed benchmarking the design and construction of the skyscraper cluster in a major city like Chongqing of China.

The purposes of this study are two folds: a) to introduce conjoint choice model to research the choice behavior of theme park users, and b) to suggest the strategies to strengthen the competitiveness of theme parks. The major four theme parks in Seoul metropolitan areas were selected as study areas. A leading polling agency was employed to select 432 respondents by probability sampling and to conduct face-to-face interview. Both alternative generating and choice set generating fractional factorial design were conducted simultaneously to meet the necessary and sufficient conditions for calibration of the conjoint choice model. Dummy coding was used to represent the attribute levels, and the alternative-specific model was calibrated. The goodness-of-fit of the model was quite satisfactory($\rho$$^2$=0.47950), and most parameters values had to expected sign and magnitude. Car was preferred transport mode to shuttle bus for visiting theme parks ; however the most ideal attribute levels only were estimated significantly. Most attribute levels of shuttle bus were estimated significantly except the Dream Land, which is the least attractive park among study areas. Simulation results showed that the shuttle bus was a mode worth providing to switch the current car dominant visiting pattern of theme parks, which will be one the effective strategies to attract more patrons, especially for potential users adjacent to parks. Several ideals were suggested for future researches, in terms of utilization of more general utility function and new base alternative, and inclusion of more salient attributes such as constraints in the model.

Purpose : The purpose of this study was to evaluate the effects of mirror movements(MM) on upper extremity's function and measure the change of MM on stroke patients depending on the elapse of time. Methods : Sixteen stroke patients with MM and Sixteen stroke patients without MM were recruited for this study. Intended movements and MM were measured by two dynanometers of MP150 system(BIOPAC System Inc., Santa Barbara, U.S.A). The upper extremity's motor function was measured using manual function test(MFT), Fugl-Meyer assesment(FMA). Results : The change rates of upper extremity's motor function test showed significant group differences in FMA but not in MFT between the patients with MM and without MM from the first test to the second test. In each group motor function generally more increased. The magnitudes of MM decreased from the first test to the second test. Conclusion : These results indicate that stroke patients with MM have a significant motor deficit. But motor deficit could be recovered by spontaneous recovery or treatments and a clinical sign of MM was improved. In the future, we suggest that studies of assessments of MM after rehabilitation and treatment interventions of MM on stroke patients.

Clearing trace of symbol which was gone with a series of pre-modern architecture history since the modern architecture (pursuing true nature from tradition which is repeated and imitated unconsciously). That is, What is the course of deconstruction? In the early part of the 20th century, We still accept the necessity of decoration in spite of its existence at one time being threaten. This means, even though symbolism in architecture has relative importance by situation of Times, it plays an important role to add the past to current style through 'Symbol'. The history of Times, a carrier which reflects Present on New Futures, makes memory by gathering data but we can not amplify our historical imagination with only data. Data is a past memory and evidence but we can not substitute that for historical experience. And it is difficult for future generations who don't live through that history to change their historical recognition with recollecting memories. They have to draw history with data but it is very limited in itself. However, They can collect historical memory through symbol in architecture. In this study, We pay attention to the symbolism of a memorial hall architecture. So We'll analyze dichotomy concept of Barthes's signifiant and signifie, visual sign and course of symbolic meaning on basis of Daniel Libeskind's Jewish Museum.

Virtual reality (VR) and augmented reality (AR) technologies can interact intuitively using virtual 3D images. Information signs on buildings that are frequently used by the public play a very important role in conveying information. However, the current information sign has different understanding and interpretation, and it is difficult to communicate quickly and intuitively for interaction. The purpose of this study is to increase the efficiency of information signing through information provision using mobile augmented reality. The InfoAR app not only guides you to the destination of the building, but also acts as a marker for the logo image. The logo image created based on the feature points recognizes the information of the destination. It is converted to AR through a mobile app, allowing users to easily find their destination by obtaining specific information. In addition, it presents interactions that can enlarge, reduce, move, and rotate information about virtual objects augmented through a function called AR. In the future, if user convenience and usability of the interface are added, research is conducted, and the level of completion is improved, such as using VR contents and promotions and business cards, it is expected that highly useful contents will be produced.

In this study, the structure model including the role of servicescape focusing on service participation and customer experience in theme park service is demonstrated empirically. The servicescape construct of theme park service includes three factors such as ambient atmosphere, functionality and layout, and sign, symbols etc. Customer service participation includes suggestion, passion and citizenship. And the emotional and convenience factors are included to customer experience. As an analysis result of examining the 241 respondents of university students, some implications were described. Customer satisfaction is greatly influenced by customer's participation in theme park service, and customer's participation has a significant effect on improving customer satisfaction by inducing customer experiences. It is desirable to consider servicescape priority in order of signs and symbols, ambient atmosphere, functionality and layout factor. The customer's participation in service is a passion for participation, citizenship, and suggesting for problems or improvements. Therefore, participants in planning and designing servicescape in the future, including IT services, should be creative in the direction of inducing various participations of customers and creating positive experiences for customers. In order to apply these findings to the composition of servicescape, the participation of various experts is required. Also, the expertise and competences of various fields must be gathered for each issues, and a more creative and scientific approach is required.

The coastal and offshore fishery to manage from a fishery permit system in our country at present seems to be a sign of lots problem, which are illegal fishing, a permit rent, non fishing vessel the purpose of vessel reduction, fishery compensation, tax exemption oil, the excessive occurrence of administrative cost due to differences during a period of a fishery permit. All the readjustment system for the permit has suggested an effective solution for a fishery permit management, the maintenance of a fishery order(the prevention of illegal fishery), the prevention of unused fishery, the entrance of new vessel in coastal fishery and it's system has prevent this problems in ahead. This paper has estimated an prevention convenience for an illegal spill of the tax exemption oil, actual effects of vessel reduction, the conservation of fishery resource for the future value and carried out an economic analysis to estimate compliance cost for the system introduction. Also, this study have analyzed throughly the coastal fishery situation and catched lots of issues on the management for the permit system. Especially, the problems improving the readjustment introduction for the permit have estimated the social and economic effects quantitatively and qualitatively with a calculated technique to classify various scenarios. This paper has judged correctly the term of validity for the permit to shorten as a result of the estimation and it will be to take the net convenience cost 1,655thousand million won. The results of this study have expect to provide a basic data to introduce the readjustment system for the permit.
