In order to construct an efficient monitoring system for major port cities in Korea, the first step to build and manage related laws and institutional infrastructure with strengthen the cooperation of the relevant agencies, regional port authorities, and port corporations. Second, for the management of air pollutants emitted by ports, a management system should be established through systematic inventory source inventory and real-time monitoring system. Third, active countermeasures should be established to reduce the emission of air pollutants by sources such as ships, harbor equipment, and trucks. This will improve the air quality of major port cities and move them to clean port cities.

Ever since the industrial revolution, large cities have become a field of new lifestyle and urbanization, causing climate change and environmental pollution. As a result, countermeasures for revolving these problems is needed. In addition, large cities in the information age have become a space where each nation executes its public policy to express the competitiveness of each city. In this study, countermeasures for the environmental crises caused by urbanization as well as the sustainable spatial designs for the cities are investigated as a new source of urban competitiveness, and the environmental aesthetics for designing public space is considered. The purpose of this study is to suggest a direction for sustainable designs and planning that is applicable to public space. According to the definition of sustainability, the items of the spatial implementation of ecological, economical and social sustainability are categorized. Based on this categorization, the sustainable designs of public space are classified into five types, and a comprehensive analysis of good public spaces from previous literature is conducted. The concepts of design and three elements--public space, sustainability, and their instrumental meanings, are integrated in this study. The significance of this study lies in the actual application of the classification to the planning and design of sustainable public space in cities, rather than being a conceptual classification.

Since the atmospheric clearness index is main factor for evaluating atmosphere environment, it is necessary to estimate its characteristics all over the major cities in Korea Peninsula. We have begun collecting clearness index data since 1982 at 16 different cities in South Korea and estimated using empirical forecasting models at 21 different stations over the North Korea from 1982 to 2006. This considerable effort has been made for constructing a standard value from measured data at each city. The new clearness data for global-dimming analysis will be extensively used by evaluating atmospheric environment as well as by solar PV application system designer or users. From the results, we can conclude that 1) Yearly mean 63.5 % of the atmospheric clearness index was evaluated for clear day all over the 37 cities in Korea Peninsula, 2) Clear day's atmospheric clearness index of spring and summer were 64.6 % and 64.8 %, and for fall and winter their values were 63.3 % and 61.3% respectively in Korea Peninsula.

This paper analyzes the existing transportation systems of Nigeria and Korea and proposes a new railway and roadway design for Nigerian cities. The research findings and feasibility study revealed that the state of Nigeria's transportation system was critical as was its market segment, infrastructural deficit and financial requirement needed to implement a smart transportation system. The dilapidation of the existing infrastructure coupled with poor maintenance culture and limited public transport services has hindered the economic growth of Nigeria and its cities. A case study of Korea and Japan shows some possible solutions to Nigeria transportation challenges. Analytical and descriptive methods were used to critically assess the infrastructural challenges, movement, and convenience. The study proposed the design of a new intercity railroad and roadway across Abuja, Enugu, Lagos and Port Harcourt cities. The proposed designs have been established to be an innovative solution with advanced benefits over the current system. The implementation of the proposed designs is estimated to cost about US$(77,832,027,719) across the study areas. Thus, the discussion, conclusion, and recommendations given present a proposal to the Nigerian government on the possibility of solving the Nigerian intercity railroad and roadway transportation challenges across Abuja, Enugu, Lagos and Port Harcourt cities through smart designs.

The intent of this paper is to identify key actors of a sustainable Smart City and define metrics that will allow assessment and better management of Sustainable Smart Cities. The paper is organized in two major segments. The first segment reviews the definition, six components, six action items of Smart Cities. It describes briefly a sample Smart City project and presents a selection of different dimensions along which Smart Cities are ranked and the rankings. The segment also discusses the technology architecture of a Smart City and then examines the definition and components of an innovation platform. The second presents the original contributions of the paper. It first introduces the dynamics created seven key actors of a Smart City ecosystem and describes their existing and potential contributions. It then defines Innopreneurship platform and presents a triple bottom line based quality metric to evaluate such a platform. This segment also discusses reengineering an economy and suggests a Smart City's Innovation Platform Score. The actions to be taken by the key actors of a Smart City in order to make it a Sustainable Smart City are described in several subsections. We hope these concepts and metrics will be a good starting point and will be refined over time by others.

The purpose of this study is to analyze the learning tendency of rural residents participating in lifelong education. The analysis data were analyzed using a polynomial model for 3,685 people using raw materials from a lifetime education survey. According to the analysis, participants in rural residents prefer small study groups. They were also approached on a practical level, such as life-help or self-realization. And the participating education programs were highly involved in vocational non-formal education. Based on the workings of personal backgrounds, participation of people with lower income and lower educational backgrounds is more active than in urban areas. In addition, the effect of improving the quality of life through lifelong education was shown in the order of big cities, small cities, rural areas. These results suggest that ways to improve the quality of life through lifelong education are not suitable as a means to maintain rural population.

Recently, the importance of competitive cities has emerged, and many cities around the world are striving to gain competitiveness. Domestic cities are also enhancing their competitiveness by taking advantage of the city's uniqueness and locality with strategies differentiated from other cities, and interest in city brands is increasing. This study seeks to enhance the city brand by improving the landscape elements of the airport, a representative international entrance. Through Instagram's hashtag function, it aims to derive elements of landscape preferred by airport users and to find ways to enhance Busan's city brand based on them.

Rapid urbanization has fostered development of modern cities. Although Conventional zoning played its role to control urban development, it also segregated land uses and created homogeneous development pattern. Mega cities with satellite bed towns has not shown their unique identity and characters. In order to develop comprehensive approach which may bring social and physical enhancement can be difficult to achieve by considering city as a two dimensions. On contrary, extensive analysis and proposals require an approach which can perceive city with three dimensions. Form-Based Codes (FBCs) are appeared as an alternative to conventional zoning with different design process and principles. FBCs approach urban place with three dimension and giving priority to form rather than land use. The purpose of this study was to analyze the necessity of FBCs and its concept, components and how this would change urban characteristics in the aspects of architectural design through analysis on 4 case studies for zoning codes of US cities. Through comparison of components in Form-Based Codes of 4 different cases, this study can show the reasons for differences in application of Form-Based Codes and how detailed components would play a role to establish better urban environments.

Modern cities have been clustered with spaces defined by specific functions, while standardized with well-defined areas. The monopoly of the function reduces the publicity of the space and hinders people's daily communication. Street also be overwhelmed by the function of being a "passage", traditional streets were losing their liminality. In fact, the street was a place of meeting, a place of events, and a place of freedom to broaden the choices of behavior. The freedom to stop or walk on one'sits own, be attracted by unforeseen events that are available on traditional streets, has become rare on the streets of big cities. Life has become dull and monotonous, too, through the modelling of the street system. Cities have become grim as communities are cut off and fragmented. In today's big cities, public attention to the liminality of the traditional streets need to be aroused so that people could gather freely and have a festival time.

This study evaluated the importance between the major indicators of living SOC in small and medium cities. AHP layer analysis was performed on a group of experts and their importance and priorities were evaluated. The results of the assessment are as follows: First, the village(walking) living zone was considered relatively more important than the local hub(vehicle) living zone. Second, the importance of health care in the local hub(vehicle) living area was assessed to be the most important in the comprehensive evaluation. Third, medical care, care, education and convenience in the village(walking) living area were ranked second, third, fourth and fifth, respectively. Fourth, the relative importance of physical education, learning, physical education, learning, relaxation, culture and village(walking) living areas in the local hub(vehicle) living areas were valued low. It is necessary to seek living SOC policies and directions in consideration of the special nature of urban social structure in small and medium-sized cities in Korea.
