  • Korean government has developed the 1st version of the National ITS Architecture in 1999 and utilized it as the framework for ITS planning, design, and standardization. The National Architecture now needs to be revised to accommodate environmental changes in ITS market and advancement of ITS core technologies. This study evaluates the current version of the architecture and suggests the directions for revision for a new national ITS architecture. The two most popular methodologies for architecture development-the process-oriented approach and the object-oriented approach-were reviewed, and the process-oriented approach was selected for new architecture development. The concept of the national architecture was then newly defined based on evaluation of the existing architecture. The new National ITS Architecture is suggested to be composed of ITS user services, logical architecture, physical architecture, and project architecture. This study must be followed by actual architecture development efforts and supporting policy actions for successful deployment of the new National ITS Architecture.

  • The study employs the conceptual framework of the strategic success paradigm developed by Ansoff (1990). The strategic success paradigm denotes that optimal performance will be attained when the level of environmental turbulence is aligned with the strategic aggressiveness and organizational capability. Based on the paradigm, authors developed the concept of IT (information technology) aggressiveness (IT aggressiveness henceforth) and capability (IT capability henceforth). In order to clarify the different concept of IT aggressiveness and capability, the author brought the concept of IT architecture. The difference of capability and architecture lies in the depth of technical considerations. Where capability refers attitudinal aspects of managers, architecture emphasizes technical capacity of the organization as a whole. The study validated the need for alignment among IT architecture, environmental turbulence and IT aggressiveness. The imbalance between IT strategy and IT architecture (such as a higher level of IT aggressiveness but a lower level of IT architecture, or vice versa) has a marginal contribution to the organizational IT performance. The alignment among organizational environmental turbulence, IT aggressiveness, and IT architecture resulted in an optimal level of IT performance especially in a turbulent environment.

  • 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.

  • The purpose of this paper is to evaluate environmental friendliness for facilities of national park to improve naturalness of national park. We have evaluated environmental friendliness of the facilities in Chirisan national park in terms of resource conservation and environmental integration, which are consisted of 9 and 8 evaluation indicators, respectively. Environmental friendliness of the small facilities was not good due to not using locally obtained materials and natural material, and that of large and complex facilities was bad in the field of excessive damage during construction, inadequate maintenance, use of natural material, locally obtained material, environmental integration with surroundings. In evaluating environmental attributes, new facilities is better than the older ones. The small facilities appeared to be worse than those of the complex, and the large facilities are the worst in terms of environmental friendliness. In general, environmental friendliness turned out to be lower in the light of the facilities in the clustered area than those of the facilities of the other area. In the future, It is required that criteria for evaluating environmental friendliness of natural park facilities is established.

  • In this Study, indicators for the evaluation of environmental amenity were determined through the investigation of the resident's consciousness in all thirty one cities and counties of Kyonggi. Also, environmental amenity that the resident feel in terms of recognition level was evaluated and based on the determined environmental indicators, environmental amenity for the physical environmental situation was evaluated. By analyzing the results, basic data for the planning of the future environmental management were prepared. The results of this study can be summarized as follows First, the developed indicators for the evaluation of environmental amenity consist of four intermediate evaluation items and fifteen individual evaluation items, and fifty four evaluation standards in total . Two to five evaluation standards were determined for the respective individual evaluation items. Second, using the developed indicators, the evaluation of environmental amenity were implemented based on both resident's consciousness and statistical data. Third, by analyzing the difference between two evaluation results, future research plan was proposed.

  • In the optimized structure sizing, the optimization methods are inserted in this context in order to obtain satisfactory solutions, which can provide more economical structures, besides allowing the consideration of the factors related to the environmental impacts in the structural design. This work proposes a mathematical model for the optimization of steel-concrete composite beams aiming to minimize the monetary cost and the environmental impact, using the Harmonic Search optimization method. Discrete variables were the dimensions of the steel profiles and the thickness of the collaborating slab of the composite steel-concrete beam. The proposed model was implemented in Fortran programming language and based on improvements in the structure of the optimization method proposed by Medeiros and Kripka (2017). To prove the effectiveness and applicability of the model, as well as the Harmonic Search method, analyzes were performed with different configurations of steel-concrete composite beams, in order to provide guidelines that make the use of these systems more streamlined. In general, the Harmonic Search optimization method has proved to be efficient in the search for the optimized solutions, as well as important considerations on the optimization of the monetary and environmental costs of steel-concrete composite beams were obtained from the developed examples.

  • Environmental Impact Assessment(EIA) is developing as a tool for environmentally sound and sustainable development in Korea. For more effective implementation of it, we try to apply Environmental Information System (EIS) to EIA process. EIS is composed of geographic and attribute data related to environment and Geographic Information System(GIS), and it will be applied to scoping, prediction, and alternative assessment, etc. in EIA. This study focuses on application of geographic data using GIS in suitability analysis of alternative assessment. We use TIN, buffering, and overlaying in GIS functions.
