  • This study was performed to investigate the awareness of Namak Eco-city, a willingness to move to an ecological city and their related variables. Data was collected through a questionnaire survey given to 491 residents who live in Mokpo, Kwangju and Muan in Chollanam Province. The awareness of Namak Eco-city was medium level and half of the respondents were not aware of that. Multiple regression analysis was conducted to estimate the effects of the variables on the awareness of Namak Eco-city. The most significant variable was the awareness of taco-city. Thirty eight percent of the respondents were willing to move to Namak Eco-City. Two variables were related with willingness to move to the city. Those who were aware of an Eco-city and had more commuting-oriented housing value had more willingness to move to the city.

  • Paris hasn't experienced such excitement since the huge changes brought about by Baron Haussmann in the 19th century. Paris Rive Gauche project, started in 1991, is the largest urban project in city ever since, it represents about 1% of Paris territory. It takes place on a workshops, factories and warehouses area that prospered along the Seine river and the railways in the 19th century. Originally planned as a business quarter, Paris Rive Gauche, developed by SEMAPA for the City of Paris, fosters urban diversity through housing, offices, public facilities, shops, creating a stimulating neighbourhood where 18,000 residents, 30,000 students as well as 60,000 employees will soon croth paths. This project's main principles are urban and social diversity, deployment of public facilites, the development of new university campus inside the city, promotion of industrial patrimony and connecting the old 13th distict to the river and the opposite side. Half of the project is going to be built on a concrete slab that covers the railway tracks which is one of the major performances of this long-term project. This concrete slab represents the new level of the City, about 6 to 8 meters above the railway tracks. We distinguish three families of buildings on the cover : Classic buildings; Bridges buildings and Connection buildings, these last guarantee the linkage between old and new level of the City.

  • This study measures whether people who are expected to live in the new city of Namak are environmentally and ecologically aware, and it investigates which variables are related to their willingness to move to an ecological city. This study investigated the environmental cognition of inhabitants in Chollanam Province; it focused particularly on ecologically -oriented values, environmental knowledge, environmental management behavior, and the awareness of an ecological city. For the purposes of this study, 500 inhabitants from Mokpo, Kwangju and Muan who are expected to live in a new city of Namak were surveyed. Awareness of the ecological city was at medium level; half of the respondents were not aware of an ecological city. Multiple regression analysis was conducted to estimate the effects of the variables on the awareness of the ecological city. The most significant variable was environmental knowledge. Next, experience in environmental education and homeownership affected awareness. Half of the respondents were willing to move to an ecological city. Among all of the variables, seven variables were significantly related to the willingness to move to an ecological city.

  • The dispersion of recycled particulates in the complex coastal terrain containing Kangnung city, Korea was investigated using a three-dimensional non-hydrostatic numerical model and lagrangian particle model (or random walk model). The results show that particulates at the surface of the city that float to the top of thermal internal boundary layer (TIBL) are then transported along the eastern slope of the mountains with the passage of sea breeze and nearly reach the top of the mountains. Those particulates then disperse eastward at this upper level over the coastal sea and finally spread out over the open sea. Total suspended particulate (TSP) concentration near the surface of Kangnung city is very low. At night, synoptic scale westerly winds intensify due to the combined effect of the synoptic scale wind and land breeze descending the eastern slope of the mountains toward the coast and further seaward. This increase in speed causes development of internal gravity waves and a hydraulic jump up to a height of about 1km above the surface over the city. Particulate matter near the top of the mountains also descends the eastern slope of the mountains during the day, reaching the central city area and merges near the surface inside the nocturnal surface inversion layer (NSIL) with a maximum ground level concentration of TSP occurring at 0300 LST. Some particulates were dispersed following the propagation area of internal gravity waves and others in the NSIL are transported eastward to the coastal sea surface, aided by the land breeze. The following morning, particulates dispersed over the coastal sea from the previous night, tend to return to the coastal city of Kangnung with the sea breeze, developing a recycling process and combine with emitted surface particulates during the morning. These processes result in much higher TSP concentration. In the late morning, those particulates float to the top of the TIBL by the intrusion of the sea breeze and the ground level TSP concentration in the city subsequently decreases.

  • 글로벌 스마트도시 추진 동향을 기반으로 2018년 '4차산업혁명위원회'는 국내 스마트도시 정책의 방향과 관련하여 '지속가능성'과 '사람중심'을 핵심 키워드로 선정하였다. 이에 따라 국내 스마트도시사업 추진단계별로 적극적인 시민중심의 혁신 방법론인 리빙랩 프로그램을 적용하고 있다. 스마트도시는 리빙랩을 통해 시민이 중심이 되어 지역문제를 발굴하고, 공공·전문가와 함께 시민의 니즈(Needs)를 반영한 해결방안 도출을 통해 지속가능한 도시문제 해결방안 및 지역발전 방안을 마련하고 있다. 그러나 상대적으로 오랜 시간 운영된 도시재생사업과 비교할 때 스마트도시사업의 시민참여는 그 수준이나 지속가능성에서 상당한 차이가 있는 것으로 나타났다. 이에 본 연구는 2018년부터 2019년까지 추진된 스마트도시사업에서 수행한 리빙랩 프로그램 사례를 대상으로 도시재생사업 단계별 시민참여 특성과의 비교 분석과 Arnstein의 '참여의 사다리' 모형을 기준으로 한 시민참여 활동 수준진단을 수행하였다. 진단결과, 스마트도시사업에서 수행된 리빙랩에 나타난 시민참여 활동은 스마트도시서비스의 선정이나 해결책 구성 등에 상대적으로 높은 수준의 권한을 기반으로 지역주민의 수요에 맞는 스마트도시서비스를 선택하고 지역에 맞는 서비스의 기술수준이 결정되는 데 큰 영향을 보이고 있었다. 그러나 스마트도시 구축사업만을 위한 단발성 성격의 시민참여단 모집으로 사업 종료 후 에는 대부분의 시민참여활동이 중단되고 있었다. 이에 반해 도시재생사업의 시민참여 활동은 지역공동체 중심으로 사업 계획 단계부터 사업 종료 후 운영단계까지 지속적인 운영·관리 방안이 도출되고 있었다. 본 연구는 이와 같은 도시재생사업과 스마트도시사업간의 시민참여의 특성 비교와 수준진단을 통해 보다 지속가능한 스마트도시 구현을 위한 시민참여활성화 방안을 제시하였다.

  • 전화선을 이용한 대화는 쉽게 도청되므로 개인의 비밀을 보장할 수 없다. 본 논문에서는 비밀이 보장되는 안전한 통신을 위한 비화기(scrambler)설계 및 실시간 구현을 제안하였다. 특히 동기 신호가 요구되지 않는 비화기 시스템을 설계함으로써 송신단의 동기 신호 첨가 하드웨어와 수신단의 동기 신호 검출 하드웨어가 필요없게 되므로 하드웨어적인 복잡성을 줄여 실시간 구현의 용이함을 얻었으며, 비화기 시스템에 새로운 이득 요소(gain factor)를 첨가하여 비화된 신호가 암호해독에 대한 안전성을 갖도록 하였다.

  • A Technology Roadmap (TRM) is extensively used as a tool to manage activities of researching and developing technologies and products that can help a business achieve its goals. However, most of past studies on TRMs have limited themselves to developing in a single product or a single industry level. Few research studies have examined how TRM are used for convergence products and services for future development. The aim of this chapter is to introduce a TRM development methodology for u-City technologies and to consider its possible application at the R&D program level in Korea. This research suggests ways to develop a TRM in u-City development by segmenting u-City technologies, projecting TRM for each technology and designing TRM templates for evaluating both current and future technologies. In addition, the study further highlights to prioritize which technology is favorable for the implementation based on its economic feasibility and technological maturity.

  • The purpose of this paper was developing a development density control model for urban growth management, using system dynamics modeling. The density control model was developed to see how urban growth, transition, and decay occur depending on the interaction among population, houses, industry structure, land and urban infrastructure such as road, water supply, and sewage treatment facilities. Suggesting adequate level of development density control using the model was another purpose of this paper. The model was applied to An'yang city to estimate the maximum number of population, industry structures, houses, and cars that can be adequately sustained with the current An'yang city's infrastructur capacity. The computer simulation results shows that the city is overpopulated by some 90,000 people. To reduce the population to the adequate level that the current urban infrastructure can sustain, the current city regulation on floor area ratio are needed to be strengthened at least 20 to 35%.
