The purpose of this study is to understand the value of the book, To Kill a Mockingbird by Harper Lee as the most favored 'One Book' and the goals of the 'One Book, One City' programs which selected this particular book. A total of 86 'One Book' programs from 2001 through 2014 and 138 The Big Read programs from 2007 through 2015 selected To Kill a Mockingbird as 'One Book' to read. With this book, many communities discussed the sympathy toward the dignity of human being with such subjects as courage, justice, and integrity, and presented its value through book discussions, various programs and events.

The purpose of this study is to understand the current status of 'One Book, One City' community-wide reading campaign by analyzing the characteristics of the books selected during the past fifteen years. According to the lists of 'One Book, One City' Reading Promotions Projects' available from the website of the Library of Congress, the Center for the Books, a total of 1,037 books were selected by 2,220 'One Book' programs. Major findings are as follows: First, 278 books (26.8%) and 759 books (73.2%) were selected by more than two 'One Book' programs and one program, respectively; Second, three most popular books were To Kill a Mockingbird (chosen in 84 programs), Fahrenheit 451 (in 53 programs), and The Kite Runner (in 50 programs); Third, with the wide diffusion of 'One Book' campaigns, the selection of unique books by individual 'One Book' programs has increased, and the impact of the books selected by 'Seattle Reads' and 'One Book, One Chicago' has gradually decreased.

Until now, u-turn lane installation methods have been studied variously. But, There is no specific standard yet. This study ranges are commercial area in Incheon metropolitan city through field investigation and presents specific design standard for efficient operation of left turn using a field data through calculating relevant permitted u-turn lane length and minimum separation distance from the front intersection to starting point of permitted u-turn lane in urban signalized intersections in commercial area. Relevant permitted u-turn lane length is found to be 32m and minimum separation distances from the front intersection to starting point of permitted u-turn lanes are 72m, 40m, 24m in case of 1 left turn lane, 2 left turn lanes and 3 left turn lanes respectively. By comparing result values and field data, they had a large difference under the similar situations in their lengths. This result is caused of no specific standard about design of u-turn lanes. If results of this study applied to design of u-turn lanes, signalized intersections in urban commercial areas would be operated more safety and efficiently.

산업의 고도화로 인한 환경오염과 하천공간의 이용이 증가함에 따라 하천 상태에 대한 관심이 높아졌다. 그러나 하천의 상태에 대한 정보를 쉽고, 정확하게 찾아 볼 수 있는 콘텐츠가 부족하다. 본 논문은 U-City에서의 쾌적한 도시환경을 위한 서비스의 일환으로 하천 주변 환경의 오염에 대한 정보를 제공할 수있다. 하천의 구간별 하천수와 하천토양의 오염도를 측정하여, 수질환경기준에 따른 수질분석 결과를 시각화한다. 시각화는 전체 수질 및 토양에 관한 시각화와 각 오염물질의 변화량을 동시에 3차원으로 시각화하여, 직관적이고 정확한 정보를 제공받을 수 있다. 또한 인터넷 포털사이트의 지도 서비스와 연계하여 사용자들의 접근성을 높일 수 있다.

국내 유시티 개발에 있어서는 다양한 교통정보서비스들을 계획하고 구축하고 있다. 그러나 표준화된 서비스 모델이 제시되어 있지 않아서 서비스 내용이 중복되거나 각 서비스간 연계에 있어서 효율적으로 이루어지지 않고 있다. 본 연구에서는 기존 유시티 구축사례들을 중심으로 실시간 교통서비스들을 조사 분석하여 효과적인 실시간교통서비스 통합모델을 제시하였다. 아울러 그에 따른 장비선정 및 구축 가이드라인을 제안하였다. 이에 따라 추후 유시티를 구축할 때 표준화된 서비스 모델에 따라 비용효과 및 연계의 효율성을 기대할 수 있다.

Remote sensing image segmentation plays an important role in realizing intelligent city construction. The current mainstream segmentation networks effectively improve the segmentation effect of remote sensing images by deeply mining the rich texture and semantic features of images. But there are still some problems such as rough results of small target region segmentation and poor edge contour segmentation. To overcome these three challenges, we propose an improved semantic segmentation model, referred to as MRU-Net, which adopts the U-Net architecture as its backbone. Firstly, the convolutional layer is replaced by BasicBlock structure in U-Net network to extract features, then the activation function is replaced to reduce the computational load of model in the network. Secondly, a hybrid multi-scale recognition module is added in the encoder to improve the accuracy of image segmentation of small targets and edge parts. Finally, test on Massachusetts Buildings Dataset and WHU Dataset the experimental results show that compared with the original network the ACC, mIoU and F1 value are improved, and the imposed network shows good robustness and portability in different datasets.

This study aims to present the direction of development of a policy framework to solve the problems associated with Smart Cities. For this purpose, first, after investigating the development process of domestic smart cities, we examined various cases of smart city policies being established overseas. Second, we analyzed the existing research into smart cities, in order to understand the relationship between the major issues. Third, an expert interview was conducted based on the identified issues. Fourth, we presented the direction of development of a Smart City policy framework to solve the major problems associated with domestic and foreign smart cities. In the policy framework presented in this research, after subdividing the elements used for solving each problem, we linked them with the smart city components and selected matching executable agents to prepare solutions. Then, once the deliberation process of the National Smart City Committee and the Smart Urban Service Support Organization has been completed, the government will support it financially and politically. It also suggested that it is necessary to perform continuous information gathering and monitoring work, along with the construction of a control tower to strengthen the network effect between smart city related markets. This research has significance in that it presents the procedures required for efficiently responding to the problems arising in the smart city promotion process. It is expected that it will serve as the basis for establishing policies dealing with the development and advancement of domestic smart cities in the future.

The purpose of this study is to investigate how smart tourism is applied to hotels and residences using ICT in Korea. Smart tourism is similar often used as a concept such as u-tourism, e-tourism, and digital tourism but the most similar of ubiquitous. This is reflecting to the fact that the recent trend of tourism has been decreasing from the large scale to the individual but the customers demand has been increasing, so we have examined how the hotel and the residence are adapting this situation. As a results, hotels and residences in Korea are reflecting to improve work process and remodeling of customer service.

국내에서 2003년부터 이슈화 되기 시작한 유비쿼터스 컴퓨팅 관련 기술은 하나의 기술을 너머 새로운 패러다임으로 자리잡고 있다. 정보통신 분야 기술인 유비쿼터스 컴퓨팅 관련 기술은 초기의 원천기술 개발에서 발전되어 다양한 분야에 활용되기 위한 각종 연구가 진행 중이며, 특히 u-City를 필두로 하여 이를 건설 분야에 도입하기 위한 연구가 매우 활발하다. 그러나 대부분의 활용 연구는 이제 시작단계이며, 실제 관련분야 도입에는 아직 많은 시간이 필요할 것으로 예상된다. 본 연구에서는 이러한 연구에 선행되어야 할 센서 데이터 표준화에 대한 연구이며, 기존 국내외 각종 연구에서 제시된 이론적 연구를 실제 구현해 보았으며, 이를 통해 나타난 각종 문제점을 보완하여 새로운 데이터 표준화 방식을 제안하였다.
