Many cities in developed countries are showing their unique urban image reflecting their own culture, history, and aesthetic tastes. Especially color, one of the major design elements, has greater impact than other visual factors to form an unique urban characteristic. Despite the long history and cultural background, Seoul as a capital city of Korea does not have been successful to show an unique city image with the perspective of color. As a leading city of design, Seoul is trying to make its own urban identity through the symbolic environmental color, 'Seoul Color'. The purpose of this study is to identify the perception on the Seoul Color established by Seoul City among design practitioners and to suggest strategies for implementing the 'Seoul Color' in various fields of environmental design to set up un unique urban image of Seoul City. For this purpose, questionnaire survey was used and 77 questionnaires were analysed. Although most of the respondents did not know the 'Seoul Color', they recognized the importance of it as a major tool of building an unique urban identity of Seoul City. Respondents recognized the representing color image of Seoul as gray. Therefore, it shows a need for environmental policy to make an eco-friendly and lively city image of Seoul instead of current monotonous image. Also in order to make a unique urban image of Seoul city, 'Seoul Color' should be applied to the shape of landscape of Seoul differently. In addition, many strategies including advertisement, education, making up obvious goals for using the 'Seoul Color', and so on were suggested as conclusion.

The objective of this study were to identify the state of re. cognition and attitude of residents in Seoul city about air environment and to identify factors affecting attitude toward air environment. Study object was residents in Seoul city sampled by multistage random proportional sampling. Sample size was 0.0067%(500 persons) of total residents in Seoul city. The results were divided into two parts: (1) descriptive results of recognition and attitude toward air environment, (2) results of factor analysis to classify categories of attitudes toward air environment and regression analysis to identify factors affecting attitude toward air environment. Most of resident in Seoul city recognized that air environment in Seoul city was highly polluted and was not satisfactory. Experience of damage of air pollution was reported in about 70% of residents in Seoul city. More than 60% of residents in Seoul city had concern about air environment. Attitude toward air environment were classified into four categories using factor analysis: Necessity of intervention of local government for air environment conservation, Participation of residents and enterprises for air environment conservation, Optimistic attitude about air pollution, Preference of economy. Factors affecting the above attitudes were knowledge about air pollution, knowledge about policies and institutions related air environment conservation, concern about air environment, educational level, subjective assessment of air environment, sex, marital status. In conclusion this study suggested providing information of air environment in Seoul city to the residents and to educating residents for making positive attitude about air environment conservation.

The smart city is one of the most promising, prominent, and challenging applications of the Internet of Things (IoT). Smart cities rely on everything connected to each other. This in turn depends heavily on technology. Technology literacy is essential to transform a city into a smart, connected, sustainable, and resilient city where information is not only available but can also be found. The smart city vision combines emerging technologies such as edge computing, blockchain, artificial intelligence, etc. to create a sustainable ecosystem by dramatically reducing latency, bandwidth usage, and power consumption of smart devices running various applications. In this research, we present a comprehensive survey of emerging technologies for a sustainable smart city network. We discuss the requirements and challenges for a sustainable network and the role of heterogeneous integrated technologies in providing smart city solutions. We also discuss different network architectures from a security perspective to create an ecosystem. Finally, we discuss the open issues and challenges of the smart city network and provide suitable recommendations to resolve them.

The aim of this paper is to explore the formation of the Seoul-focused network city for technological commercialization compared with Seoul as a mega city. The growth of Seoul and subsequently, the Seoul metropolitan region as a mega city and mega region has led the uneven regional development in Korea since the 1960s. To reduce a huge gap between the Seoul metropolitan and the non-metropolitan region, the concept of network city can be suggested in terms of the functional and spatial division of labor. More specifically, such division of labour throughout the formation of the Seoul-focused network city concentrates on technological commercialization which is deeply concerned with R&BD (research and business development). For this network city, there are 4 axes such as the axis of South-North Korean cooperation (the axis of R&BD for complex technologies), that of the expansion of a mega city (that of R&BD for green growth technology), that of the linkage of small and medium-sized cites (that of R&BD for life science and technology) and that of megalopolis (that of R&BD for basic technology) with regards to the axis of urban development and technological specialization. It shall be argued that the formation of Seoul-focused network city can be an alternative to the contemporary uneven regional development between the Seoul metropolitan and non-metropolitan region in Korea.

A new speed improvement method for quantitative superimposed EMG signal analysis to diagnose the neuromuscular dysfunction is described. The improvement is achieved through the use of efficient software and hardware signal processing techniques. The software approch is composed of the MANDF filter and HRWA algorithm which provides the optimal set and time delays of-selected templates. The hardware employs a TMS32OC25 DSP chip to execute the intensive calculation part. The purposed method is verified through a simulation with real templates which are obtained from needle EMG. As a results, the proposed method provides an overall speed improvement of 32-40 times.

A digital city model represents a 3D environment of a city with various city object information such as 3D building model, road, and land cover. Usually, at least two satellite images with some image overlap are necessary and a complex satellite-related computation needs to be carried out to create a city model. This is an expensive technique, because it requires many resources and excessive computational cost. The authors propose a methodology to create a digital city model including 3D building model and land cover information from a single high resolution satellite image. The approach consists of image pan-sharpening, shadow recovery, building occlusion restoration, building model extraction, and land cover classification. We create a digital city model using a single KOMPSAT-2 image and review the result.

The motivation for transforming the Seoul City Hall plaza into place for pedestrians was prompted by the 2002 World cup event. This place has diverse time layers ranging from the Yi-dynasty to the present. Around city hall, diverse cultural assets and distinctive architecture are scattered. The place is a kind of melting pot that represents different times and cultures in the city. Transforming place for cars into place for citizens suggest several implications in city making policy such as high priority for pedestrians in urban design and enhancement of the public open spaces through downtown remodelling. Our plan is to propose the idea of Media plaza. One of the characteristics of Seoul now can be summarized as Media because the W industry and infrastructure are well developed in the city. ´Seoul Media Plaza´ adopts high-tech infrastructures such as RGB color post, multi box, I-Gate, etc as design materials. Three concepts of the plan are ´evolutionary plan´, ´flexible plan´, and ´participatory plan´. First, the plan will embrace the future changes of external conditions. Second, the plan should be flexible to accomodate the diverse activities in the plaza. Another special aspect of the plan is a kind of open plan. The ground surface of the plaza will be changed in its pattern and shape by citizen participation. Finally, the ´Seoul Media Plaza´ attempts to represent the spirit of Seoul and to connect the past, the present and the future while promoting citizen participation.
