Keen attention has been directed at "smart tourism cities" due to its role of solving urban problems arising from modern tourism development. However, some local governments are making huge investments in developing uniform tourism apps without specific directions or guidelines for the transformation of smart tourism cities. Accordingly, this study aims to develop a standardized and objective smart tourism competitiveness index and evaluate the competitiveness rankings of various cities around the world. The index comprises the five subindices of attractiveness, accessibility, digitalization readiness, sustainability, and co-partnership. The analysis results have shown that Singapore is the most competitive smart tourism city, followed by Amsterdam, New York City, Seoul and Barcelona, with Ho Chi Minh and Bangkok being relegated to the bottom of competitiveness rankings. We expect that this index can be employed as a global standard for continuously and systematically monitoring smart tourism city-related projects in the future.

This study attempts to introduce the methodology for accounting real-time population distribution in the urban areas. For the purpose, we utilize the media user's time-space information from the media users' media diaries in the media panel survey databases. We analyze the space-time population rate for each activity space related with everyday urban lifes. Seoul has been selected as a case study area, since space-time information are relatively rich there, and thus the comparisons are available. The space-time population rates have been verified by the comparative analysis with the T-card results. We propose a real time population measurement method by combination of the space-time population rate with geographical data. The real time population of each activity space at each dong in Seoul has been calculated by multiplying the space-time population rates to the numbers of employer of three categories of activity spaces(residential, working, and commercial). By utilizing GIS, we visualize the results of two time points (3AM and 3PM) and then analyze the spacio-temporal characteristics of real time population distribution in Seoul. The Day time population distribution pattern shows strong relationships with the distribution of business and commercial activities, while the night time population distribution pattern can be explained by resident population distribution almost perfectly.

경제적인 풍요가 어느정도 이루어지면서 깨끗한 도시환경속에서 삶을 누리고자 하는 욕구도 증가되었다. 이를 반영하듯이 최근들어 환경에 대한 시민들의 관심이 어느때 보다 더욱 커져만 가고 있다. 이와 더불어 도시계획적 흐름도 물적계획에서 비물적계획인 인간중심 위주의 가치관으로 전환되고 있으며, 공원녹지체계의 정립, 도시경관관리방안, 자전거도로의 도입, 보행자도로의 계획과 설계, 대중교통의 활성화 등 많은 환경친화적 프로젝트들이 수행되어져 왔다. 본 연구에서도 기존의 주요 보행자공간으로 다루어져 온 보도공간에 대하여 조사연구하였으며, 도심의 외곽에 위치하고는 있지만 대구시의 남북을 관통하는 주요간선도로변에 접해 있고 보행량에 비해 보도가 지나치게 넓어 비효율적인 토지이용을 보이는 보도공간을 대상으로 하였다. 특히 도심의 외곽지 보도에 관한 연구는 통행량이 많은 도심지의 상업지나 주택지의 보도에 밀려 상대적으로 소홀히 다루어져 왔다. 이 가운데 대표성과 보편성을 가지는 곳으로 선정하여 연구를 수행한 결과 기존의 단순목적 보도공간을 4개의 공간 즉 보행자공간, 자전거도로공간, 차단 및 가로시설공간, 녹지 및 편익공간으로 재구성하였다. 이는 적은 비용과 노력으로 보행의 순기능인 쾌적성과 안전성을 보다 강화시켜나갈 수 있었다. 매연과 소음이 없고 도시민의 건강성를 확보한다는 이유로 여러 선진국에서는 수 년전부터 각광을 받고 있는 것이 보행교통과 자전거교통의 개념인 녹색교통이다. 이러한 녹색교통은 공해감소의 편익도 있지만 무엇보다 매력적인 도시환경의 창출과 인간중심적이라는 가치관에 그 의의가 있겠다.

기후변화로 인해 전 세계적으로 홍수로 인한 피해 발생 빈도와 규모가 증가하고 있다. 인구 및 사회기반시설이 밀집되어 있는 도시에서 침수가 발생할 경우 피해 규모가 막대하여 사전에 침수를 예측하고 원인을 분석하여 예방하려는 노력이 중요하다. 본 연구에서는 고해상도 물리 기반 도시 침수 모형인 H12 모형을 이용하여 과거 침수 사상을 재현하고 발생 원인을 분석하였다. 대전광역시 서구 A 아파트 인근의 도시 유역에서는 2020년 7월 30일 새벽 발생한 집중호우로 차량 78대와 아파트 2개 동이 침수되고, 사망 1명, 이재민 56명의 피해가 발생한 바 있다. 고해상도 도시침수 모의를 통해 재해 발생 원인을 분석한 결과, 좁고 긴 유역의 형상과 유역 하류에 위치한 침수 발생 지역의 낮은 지형이 복합적으로 작용하고, 폭우로 인해 상류로부터 급속히 발생한 유출이 배수가 취약한 하류 저지대에 저류되며 발생한 내수침수 재해로 분석되었다. 또한, 침수 재해 발생 이후 설치된 침수방어벽의 홍수 방어 효과를 고해상도 모의를 통해 분석하였다. 침수방어벽 지점에 고해상도 지표면 입력자료를 수정하여 모의한 결과, 침수방어벽 설치 후 침수 지역 수심이 낮아진 것을 확인하여 침수 저감 효과를 평가하였다. 본 연구에서는 초고해상도 물리기반 모형을 이용하여 정량적으로 침수 원인 분석이 가능함을 확인하였으며, 추후 침수지역의 배수구용량 산정 등 침수 대안 수립에 활용할 수 있을 것으로 예상된다.

City's inhabitants should be able to utilize a variety of urban infrastructures and public facilities in a way of possessing the convenience, amenity, and safety of urban life. Most of the city government, however has established a policy for making and providing urban park facilities based on a very simple quantitative criteria rather than the qualitative criteria such as appropriateness, utility, accessibility, equity so far. Especially in the case of urban neighborhood parks, the usefulness to the inhabitant and accessibility to the parks may be questionable. In this study, we intended to analyze the spatial equity and distribution characteristics of urban neighborhood parks and to select several potential facility sites required in the study area using GIS's spatial analysis functions. Finally this study analyzes the possible location of an urban neighborhood park in terms of objective criteria and AHP techniques.

In a situation where population decline is intensifying, the decline of local mid-small sized cities is emerging as a social problem. The decline will increase the difficulty of supplying demand-based living services. Therefore, increasing accessibility to living services is important for quality of life. With this background, the purpose of this study is to derive living zones that can use high-order services in metropolitan cities through high-speed railway. To this end, the behaviors of residents in mid-small sized cities were investigated through a questionnaire, and living zones and vulnerable areas were derived through a GIS analysis. The results of the study are summarized as follows. First, most of the residents had experience using cultural, medical, shopping, and educational services in metropolitan cities. Second, the time required to visit a metropolitan city for the use of higher-order services was about 2 hours, and the desired time was about 50 minutes. Third, when accessibility is improved, the willingness to use the higher-order service of the metropolitan city is high. Fourth, many regions have been derived as living zones where services of metropolitan cities can be used through high-speed rail. Lastly, the major vulnerable areas were found to be the northern area of the Gangwon region, the northern area of the Yeongnam region, the west coast of Chungnam, and the border area of Jeonnam and Gyeongnam.

The purpose of this study was to investigate the educational needs targeted at city dwellers with hope of migration to mountain areas. 80 city dwellers participating in the education program operated by Korea Forestry Promotion Institute were selected. Results showed that city dwellers had higher preference for the education including medium scale(20-40 persons)and the type of camp with field experience. Real experiences and knowledge and understanding of migration to rural area are the most important element of the qualifications of the program teachers. In the contents of education, city dwellers wanted the teaching programs about 'how to have forest land', 'how to produce the forest products', 'field experience' and 'forest tourism' and so on. In other words, city dwellers who wanted to move to mountain areas were interested in basic things for living. In addition, it will need to investigate people who have real experiences migrating to mountain areas and then it is necessary to discuss educational needs and supporting system helping people can settle in mountain areas.

This study has observed 12 parks (20 spots) in Seoul to know the number of users, gender, age groups for the units of 30 minutes from 06:00AM till 10:00PM. According to the systematic characteristic of the surveyed outdoor exercise place, the details of their users during the summer time were analyzed from the objective viewpoint. Major results of analysis are as follows: Firstly, in case of the riverside of the Han River 07:00AM marked a mini peak and 21:00PM reached the peak, and in case of sub-stream neighborhoods, 21:00PM showed only one peak. On the other hand, in case of neighborhood parks (including pocket park) no peak time was noticeable. Secondly, in case of the riverside of the Han River and the neighborhoods of sub-streams, people used the exercise equipment remarkably at night, and in case of neighborhood parks people used the exercise equipment a little bit more in the morning than in the afternoon. Thirdly, in case of nights in summer the riverside of the Han River was preferred by men, while the neighborhoods of sub-streams were preferred by women and the neighborhood parks showed no difference in the number of users among men and women. Fourthly, differently from men, women do not regard the exercise so seriously as men and their purpose of using outdoor exercise place is to use their leisure time mostly with their family members or neighbors, and women prefer light and comfortable exercises. Fifthly, in summer even those who like to exercise a lot like to exercise in the morning to avoid summer heat. Therefore, provision of shades in summer is very important.

The rapid increase in the number of climate disasters combined with the scale of change and the diversification of natural disasters require a radical solution. In particular, the urban space is more complex, therefore we need to establish measures for disaster response and how to react to damaged infrastructure based on the phenomenon of an increase in the urban population and the impermeable layer being extended. The social problems related to the economic burden of land purchase and the securing of a disaster prevention system can be solved simultaneously by introducing the park system for disaster reduction into the public land of the green space in the city. The local government has recently adapted diverse systems of disaster mitigation and carried out pioneer projects according to the guidelines for the construction of the urban park for disaster prevention published by the Ministry of Land, Infrastructure and Transport. The purpose of this study is to propose a composition model for neighborhood parks to prevent disaster through urban green spaces which has the functions of water management and biotope conservation. The result of this study will contribute to utilize the climate change adaptation model for living area neighborhood parks in the existing urban structure.

Applying the construct of country image this study examined city image for Daegu in Korea. Study 1 measured the city image for Daegu and Seoul, identified the city image dimensions, and compared the images of the two cities. Study 2 confirmed the city image dimensions and examined the Daegu image by residency and demographic characteristics of respondents in Daegu and Seoul regions. The study extracted 4 dimensions of city image including economy, people, conservatism, and development capability. High conservatism and low economic prosper represented the image of Daegu while the opposite did of Seoul. Regardless of residency, single and Young respondents with high income and education had negative images for Daegu, and residents in Daegu rather than in Seoul had more negative images.
