Digital twins are digital replicas of objects and systems in the real world. These digital replicas in a virtual environment can be connected with smart sensors and a variety of analyses, and simulations of real-time data from these sensors enable effective the operation, rapid feedback, and future predictions of real world phenomena. Until now, digital twins have been adopted and used mainly in the field of manufacturing, especially for smart factories. As digital twins are expected to be useful not only for productivity improvement but also for social problem solving, it is predicted that they will be extended to other fields such as those of transportation and cities. Digital twins will especially help realize smart cities through real-time monitoring, operation, and predictions using virtual digital twin cities. This paper summarizes the trends in digital twins for smart cities, the concept of digital twins, their application to smart cities, the strategies of various countries, and the development status of companies.

The rapid development of economy in China at the expense of consuming huge amount of energy and resources, water resource in particular, which has resulted in the production and discharge of increasing amount of wastewater to the water environment. In order to effectively control the increasing water pollution trend, the State Council has stipulated that all the cities with population over 500,000 should reach wastewater treatment rate of 60% by 2005, and all the cities should reach the rate of 60% by 2010, of which Capital Beijing and all the province capital cities and important tourism cities should reach 70% then. By the end of 2005, of the 661 cities in China, 393 have built and operated municipal wastewater treatments with a total number of 790 sets, total treatment capacity of $80.91{\times}106m^3/d$ and total treatment rate of > 48%. Other 73 cities have started the construction of municipal wastewater treatment plants, and other 168 cities have started to prepare, planning and design of wastewater treatment plants. Most of municipal wastewater treatment plants in big cities in China operate normally and perform well with good quality of effluent in terms of wastewater treatment train, but the sewage sludge treatment is usually poor with big problems. It has been found that the small scale WWTPs using activated sludge process in the towns are usually operated and maintained abnormally because of lack of fund, skilled operators and energy. It is therefore suggested that the small scale MWWTPs in small cities and towns adopt appropriate technologies, of which the most available ones are multi-stage ponds, constructed wetlands and the combination of them for further purification and reuse of treated wastewater.

The purpose of this paper is to analyze the location, population growth. and cargo concentration of Korean port-cities. In the location theory, Sommer (1976) and McGee (1967) models are newly introduced, as are the Rimmer (1967), Bird (1965), Hoyle (1981) models. which were already introduced in previous studies from Korea. Analysis of population growth in the Korean port-cities is conducted using data from 1966 to 1998. Rimmer and Hoyle's concentration models are used to measure cargo concentration from 1966 to 2000. The main results of this paper are as follows: First, Korean ports are concentrated on the East Sea, the Southern Sea, and the West Sea. Their locations are closely related with the hinterland. the inland city, and growth of port-cities. In considering the foreign countrys' cases, Korean port-cities are similar to the models of Bird and Hoyle. Second, the populations of Ulsan and Pohang grew at the fastest rate in 1966-1998, while the port cities in the Honam and Jeiu region grew at much lower ratios. Most port cities are located near large industrial complexes. Third the growth rates of Gwangyang, Daesan, Pohang, Pyungtaeg, and Samchunpo increased, while those of Busan. Mukho, Masan, Mogpo, Yeosu, and Sokcho declined. Of particular note, the growth rate of Busan remained negative after the late 1980s. Fourth. empirical results using the Rimmer (1967) model indicate that Gwangyang, Daesan, Pyungtag, and Pohang have shown the concentration. But the deconcentration was shown from the Busan, Mukho, Janghang, Gunsan, Mogpo, Yeosu, Masan, Sokcho. and Jeju. Fifth, the concentration of ports located in West coast region has shown the mixed results between concentration and deconcentration except the concentration of early 1970s and 1990s. The concentration of ports located in East coast region has shown the concentration before the middle of 1980s. And deconcentration after the middle of 1980s have appeared. The Southern coast region has shown the continuous deconcentration except the partial concentration of early 1986. and 1991. Planners of Korean ports should find out the factors of concentration and deconcentration of each ports and should determine factors such as investment priority level. size and scope in order to ensure the balanced development of regional ports and port-cities.

도시환경디자인에서의 간판의 역할은 상점을 알려주는 기능적인 면도 있지만 그 지역의 전반적인 분위기를 조성해주는 심미적인 면이 크다고 볼 수 있다. 간판이 도시환경에 미치는 영향은 크며 도시의 이미지를 결정한다. 도시환경의 구체적인 목표는 인간의 쾌적성을 확보하는 것이며 인간은 아름답고 쾌적한 도시환경에서 보다 질 높은 삶을 살기를 갈망하며 추구한다. 그러나 현재 서울을 비롯한 우리나라 도시는 난립된 광고물과 간판이 주변 환경과 조화를 이루지 못하고 있는 실정이며 도시환경의 질을 떨어뜨리고 시민들에게 시각적 불쾌감을 주는 공해요인으로 대두되고 있다. 이러한 문제점을 해결하고자 서울시와 동경도의 간판관리를 비교분석하여 서울시 간판관리의 문제점을 모색하여 보다 체계적으로 간판관리가 될 수 있도록 하고 간판 개선 방안을 모색하기 위한 기초 자료가 되도록 한다.

최근 산업도시 성장 이후 탈산업화 시대에 전개되는 새로운 도시화에 대한 논의가 포스트모던 도시, 소비도시 등으로 다양하게 전개된다. 도시화의 단계적 접근에서는 인구 변화와 이동에 기초하여 거대도시는 도시화의 후기 단계인 재도시화를 경험하고 있으며, 이러한 도시화 단계는 시차를 두고 점진적으로 하위 규모 도시에서 나타날 것으로 추정된다. 그러나 산업 재구조화는 인구 규모만으로는 포착되지 않는 새로운 도시화 특성을 유발할 것으로, 본 연구는 한국 대도시의 도시화 특성을 이동, 통근 인구 그리고 이들의 지리적, 사회적 특성에 기초하여 검토하였다. 대도시별 도시화 경험은 다르게 나타나는데, 서울은 단계적 도시화 과정을 거치지만, 다른 대도시들은 산업도시와 탈산업도시로의 전이에서 다양한 모습을 드러낸다. 특히, 지방 대도시의 경우 산업 기반의 교외화가 이루어졌으나 중심 도시의 편리한 주거, 생활 환경으로 중심 도시에 거주하며 주변으로 역통근하는 인구가 늘고 중장년층의 경제활동 가구가 대도시로 유입되며 주거 기능이 새로운 도시의 역할로 확대되는데, 이는 한국 대도시의 새로운 도시화 특성이라 하겠다.

The difference between presentation of cities in the European modern drama and its counterpart the American modern drama denotes and comes from two very different images of cities. While the European modern drama presented cities that were desolate and fantastic to certain measure, the American modern drama presented the images of actual cities that can be identified by the spectators and readers. Although one cannot 'actually' identify any actual representation of cities in both the European and the American dramas, the images of cities can be discerned in the dialogues of the characters in the plays themselves. In this perspective the images of cities that are represented in any work of modern drama are actually represented through metaphors and connotations. The images in this instance rests and can only be identified within the boundaries of psychology. The dialogues are means through which the author communicates with the spectators. Because drama is above all categorized as being a work of text before representation, deciphering drama also falls in to same cadre as any other literary texts. Through the means of 'decontextualisation' the reader/spectator identifies with the associated images that the text proposes.

Rapid economic development in Korea caused functions of city functions such as concentration of population, deterioration of the quality of living environment and traffic congestion. Korean cities have lost their identity becausr they are merged functionally and physically with neighboring cities, forming one mesa-city. Unified shape and disorganized streets of cities often cause confusion among foreigners and visitors. It is very difficult for them to find their image in strange cities. It is, however, important to correctly analyze the image and meaning of cities for understanding its identity. The purpose of this study is to develop a method to analyze the city image by focusing on some of the main cities in Korea. For this purpose, the adjective questionnaire and multi-dimension scaling (MDS) are applied to the analysis of city image. Image analysis graph by MDS can visually present the general and integrate images. The results of this study are summarized as follows: The important factors for interpretation of city image are historical and industrial character. Seoul, Taegu and Pusan have industrial and complex city images. Kongju has historical city image, while Changwon has a modern image. Chuncheon belongs to a soft and small image. Each city has an alternative solution against a negative image, according to the image analysis graph.

The purpose of this study is to classify the cities on sustainability assessment score studied in advance using cluster analysis, to present efficient management and policy direction based on analysis of sustainability index in 45 cities of all over Gyeongsangnam and Gyeongsangbuk-do. According to the results of cluster analysis, 45 cities were classed into 4 clusters by "livable-welfare city", "environmental -ecological city", "scientific-technological city", and "industrial-economic city". The livable-welfare cities must keep superior environmental sustainability, promote small and medium sized business on regional characteristic. The environmental-ecological cities have to change agriculture into future environmental industry such as ecotourism, bio-industry and landscape agriculture. The scientific-technological cities are going to need support of government scale such as income enlargement of citizen and stable job security. Finally, the industrial-economic cities must increase environmental management plants and improve quality of life through securing green spaces, maintaining public peace and applying UIS because of low quality of environment and life.
