Down-town community is an essential element for ESSD. But the population of down-town has been decreased since 1990's. Therefore this study is about how to improve the down-town residential tendency through the civic research, examination of related policies and legal system. And the result is as follows. First, Taegu has lots of problems as a residential space, that are caused by bad residential environment. They also, however, represent the validity of arrangement of down-town community and we could find the possibility for development. Second, Japan perceived the importance of down-town community and a great deal of effort was done to save residential space with various programs. But it is ignored in Korea for economic reason. Therefore we need to change our view of Down-town residence. Third, the role of government, people and specialist are important for the improvement of Down-town community. 1) The central government and ask its responsibility. 2) The local government makes the best use of present laws and is required of management with elasticity in favor of the regional character. And it need to set the future image and aim of the city. The aim should be the one that meets the practical need of down-town community and suitable programs need to be activated. 3) Generally, the citizens who are living in a region know it's problems the best. So the citizens themselves can advertise their Down-town community and participate to solve its problems 4) Down-town community requires a differential policy from general residence. Thus the professional have duty for the development of proper know-hows for Down-town community.

Purpose: The Korean government has implemented a Barrier Free Certification System since 2008 to create a secure and convenient environment for the socially disadvantaged. The drastic increase in the number of BF-certification facilities is expected due to the revision of the system and increasing the number of certification institutions. An analysis of individual evaluation items needs to be made for the BF-Certification with public confidence. Method: Korean standard, International Standard(ISO/FDIS 21542, 2011), German Standard(DIN 18040-1, 2010), Austrian Standard(${\ddot{O}}NORM$ B 1600, 2017) and Swiss Standard(Norm SIA 500 / SN 521 500, 2009) were investigated and analyzed. A comprehensive improvement plan is proposed by comparing details of the aforementioned standards and the evaluation items of BF-Certification. Results: Many problems arise in applying existing Barrier-free standards due to changes in population structure, environmental change and the use of powered wheelchairs. International standards are being improved to solve these problems. The korean standards also require improving of the Barrier Free Law and Certification System, which reflect these trends. In korean cases, standards such as the size of the doors (width and height), the Unobstructed Manoeuvring Space and Clear Space at the Latch side of the Door are required to improve standards in accordance with international standards. In addition, the expression of laws and evaluation items of BF-Certification should be clearly defined. And the application of visual contrast standards for the enhancement of perceptions presented in international standards should be considered. Implication: Barrier Free related legal standards and evaluation items of BF-Certification that are used in Korea are required to be revised in consideration of social and environmental changes. Comprehensive improvements should be made through detailed review.

Power demand has continuously increased with technological and economical development. The load density is also growing in the center of downtown area. In particular, underground facilities have been increased on the purpose of the prevention of urban disasters and pedestrian environment improvement. Based on this situation, the underground space in urban surroundings has gradually decreased because of the limited space. The ampacity of buried cables is affected by various factors such as cable size, soil thermal resistance, burial depth and filling material. The thermal capacity of the facilities is determined by the absorb heat surrounding the cable and the soil. The maximum operating temperature of cable is the highest temperature when the insulator of cable is not damaged in the case of high enough temperature. In this paper, the most effective cabling configuration is suggested using the duct array adjustment. It was also considered to increase the number of cable line. This underground distribution system was simulated by using ETAP(Electrical Transient Analysis Program).

First phoneme queries are important functionalities that provide an improvement in the usability of interfaces that produce errors frequently due to their restricted input environment, such as in navigators and mobile devices. In this paper, we propose a time-space efficient data structure for Korean first phoneme queries that disassembles Korean strings in a phoneme-wise manner, rearranges them into circular strings, and finally, indexes them using the extended Burrows-Wheeler Transform. We also demonstrate that our proposed method can process more types of query using less space than previous methods. We also show it can improve the search time when the query length is shorter and the proportion of first phonemes is higher.

Emergent computing paradigms such as genetic algorithms have found increased use in problems in engineering design. These computational tools have been shown to be applicable in the solution of generically difficult design optimization problems characterized by nonconvexities in the design space and the presence of discrete and integer design variables. Another aspect of these computational paradigms that have been lumped under the bread subject category of soft computing, is the domain of artificial intelligence, knowledge-based expert system, and machine learning. The paper explores a machine learning paradigm referred to as teaming classifier systems to construct the high-quality global function approximations between the design variables and a response function for subsequent use in design optimization. A classifier system is a machine teaming system which learns syntactically simple string rules, called classifiers for guiding the system's performance in an arbitrary environment. The capability of a learning classifier system facilitates the adaptive selection of the optimal number of training data according to the noise and multimodality in the design space of interest. The present study used the polynomial based response surface as global function approximation tools and showed its effectiveness in the improvement on the approximation performance.
