The purpose of this paper is to study a framework on building and continuing consumer trust in mobile travel and tourism content (M-TTC). Trust development life cycle in e-commerce is a trust-oriented building flow of online consumer. Travel information and content in mobile commerce is a initiative and immature step in the ubiquitous era. Travel and tourism industry is information intensive and network business between the bricks and clicks, the public and private, and the virtual and physical. A framework of travel and tourism content in m-commerce based on Siau and Shen (2003) and in perspective of information cities by Ferguson, et al. (2004) proposes conceptual components to build information and content for continuous consumer trust. The main results of the paper by focus group research methodology focus on building a conceptual m-trust model of mobile content in travel and tourism industry. Additionally, it shows what the important factor is and how the trustworthy improves continuously to the public, mobile vendors, and technological aspects.

Recently, the apartment building has been constructed in large quantities to provide housings due to the gravitation of population towards large cities. However, we're faced with a critical problem of deterioration of our dwelling environment caused by the trend toward high-rise apartment which could be an obstruction in obtaining sufficient sunlight. Therefore, there have been several legislative actions against infringement on the right of sunshine. In the building law, sunshine hours and the minimal separated distance between apartments are regulated as the criteria for the site planning, However, the minimal separated distance was defined without consideration of the parameters like building orientation and thermal effect of the sunshine hours in the site planning for the apartment building. In this study, the sunshine hours and heating energy during the underheated season for various arrangements in site planning are carefully considered and analyzed.

In this study, it is quantitatively analyzed for thermal Characteristics of isolation-heat paint which has been supplied to a domestic market through experiments and simulations. In the case of experiment using the container box, it shows 8% decrease on cooling energy consumption in a summer season, but shows increase on heating energy consumption. As a result, the analysis has found increase of energy consumption. As a result of holding simulations with meteorological data of domestic major cities, it shows an increase of energy consumption in domestic condition, and it is hard to expect an energy saving from the isolation-heat paint unless greater air-conditioning load.

This study is to analyse probability distribution characteristics of water supply demand. Two cities located near Seoul were selected as study areas. In this study, two probalility distribution types were tested using the K-S(Kolmogorov-Smirnov) method. The K-S method was used to prove the goodness of the selected distribution type. And also, the goodness of maximum day demand to average day demand ratio which was obtained by field data was tested. Conclusions are as follows. 1.Bothl normal distribution type and lognormal distribution type are appropriate as the probalility distribution type for the water supply demand. 2. The probability distribution characteristics can be used to test the goodness of the maximum day to average day demand ratio.

The many cities are changing in the city form where the person and nature are mixed. Namely, the government invests many expense in tree field of distance space for the change in the green city. In this paper, we design and implement a tree growth management system using PDA built in 13.56MHz RFID reader and CBD(Component Based Development) for ubiquitous computing environments. Our system provides history management to increase business efficiency for location coordinate of tree and history information of tree which using RFID, the RFlD tag is attaching the new tree and that is inputting GPS location information in PDA and provides tree information of tree by location coordinate to history management. Finally, we show from a performance analysis that our system achieves about 85% average tree read rate of RFID under test scenario environments.

This short paper is about the background, progress, achievement as well as the direction of Urban Regeneration (UR) Policy since 2013 in Korea. The UR in Korea has been recognized and initiated late compared to UK, Japan as well as many other countries that have achieved economic growth earlier than Korea. In 2013, the Special Law on UR established and the UR project has begun in earnest. However, there are still a number of pending issues required to be resolved for the regeneration of declining cities. After reviewing the background of UR in Korea, we would go through the progress and achievement of UR and then we look at the follow-up measures required to be resolved in short period as well as longer term for successful UR.

Purpose: The purpose of this study was to identify the needs of hospice care in families of the hospitalized patients with terminal cancer. Method: The data were collected from April to July, 2008. The participants were 100 family caregivers of hospitalized terminal patients with cancer recruited from two general hospitals in 2 cities in Korea. Needs of hospice care were measured using the 'Needs Assessment Instrument for Hospice Care in Families of the Patients with Cancer'. Results: The mean of needs score was 76.6, which meant degree of the needs was very high. Among the categories of the needs, the mean of category 'emotional care' was the highest. There were significant differences in the needs of hospice care according to sex and type of present therapy. Conclusion: Health care providers in hospital and hospice facilities must assess the needs of families as well as the patients in order to meet their specific needs. Additionally, they need to have deeper understanding of the need of emotional care and to apply emotional care to hopice patients and their families.

This paper aims to draw out the practical lessons for City Brand as aspect of urban spatial by urban regeneration project in Korea. Image of the City and City Brand is the most important element for the competitiveness of modern cities. This paper discusses the guide line or strategy of City Brand, its current status in Korea. It also examines the present Urban Regeneration in Korea, identifies the problems encountered in implementation, and suggests the solutions for strengthening urban competitiveness such as a City Brand. Also it emphasized that well planned invisible and physical environments, including story and land-mark facilities, are also crucial in making City Brand more attractive and competitive.

There is a proverb in Korea "Don't chase after another." It can be a right proverb in sometimes. However, usually it doesn't fit in these various society, information knowledge society. Modern society requires convergence technology. IBS (Intelligent Building System) requires knowledge of architecture field, electric field, communication field, and computation field. ITS (Intelligent Transport Systems) which is constructing in many cities requires various knowledge as engineering works, electricity, computation, communication and transportation. In the case of u-City, it requires technology of many fields as architecture, electricity, communication, engineering works, transportation, and computation. Anyone who wants to participate in u-City should study and acquire knowledge in various field. Otherwise, it must be failed because of lack of communication like as the Tower of Babel. U-City is not a portion of one field. Therefore, engineers in many fields should cooperate with each other to make u-city as the best product in the world.

Various aspects of the air quality problems caused by ambient particles in and around the city of Seoul are discussed. First, the trend of the air quality in Seoul over time is investigated along with the types and quantities of energy consumption in Seoul. It was found that the general air quality in Seoul has improved over the last twenty years because of a change in the primary fuel used in Korea. However, the visibility in Seoul, a representation of the ambient particle concentration, is still worse than in other cities in Korea. In the air around Seoul, secondary particle generation might be as important as particles directly emitted from within the city or transported from outside.
