Energy efficiency is vital to improve energy security, environmental and social sustainability, and economic performance. Improved energy efficiency also mitigates climate change by lowering greenhouse gas (GHG) emissions. Buildings are the single largest industrial consumer of energy and are therefore key to understanding and analyzing energy consumption patterns and the opportunities for saving energy at the district level in urban environments. This study focused on two representative boroughs in the major metropolitan area of Seoul, South Korea as a case study: Gandong-gu, a typical residential district, and Jung-gu, a typical commercial district. The sources of the energy supplied to the boroughs were determined and consumption patterns in different industry sectors in Seoul used to identify current patterns of energy consumption. The study analyzed the energy consumption patterns for five different building categories and four different sectors in the building using a bottom-up energy modeling approach. Electricity and gas consumption patterns were recorded for different building categories and monthly ambient temperatures in the two boroughs. Finally, a logarithmic equation was developed to describe the correlation between commercial activity and cooling energy intensity in Jung-gu, the commercial district. Based on these results, recommendations are made regarding the current energy consumption patterns at the district level and government energy policies are suggested to reduce energy consumption and, hence, greenhouse gas emissions, in both commercial and residential buildings.

The objective of this study was to genetically characterize isolates of Giardia duodenalis and to determine if zoonotic potential of G. duodenalis could be found in stray cats from urban and suburban environments in Guangzhou, China. Among 102 fresh fecal samples of stray cats, 30 samples were collected in Baiyun district (urban) and 72 in Conghua district (suburban). G. duodenalis specimens were examined using light microscopy, then the positive specimens were subjected to PCR amplification and subsequent sequencing at 4 loci such as glutamate dehydrogenase (gdh), triose phosphate isomerase (tpi), ${\beta}$-giardin (bg), and small subunit ribosomal RNA (18S rRNA) genes. The phylogenetic trees were constructed using obtained sequences by MEGA5.2 software. Results show that 9.8% (10/102) feline fecal samples were found to be positive by microscopy, 10% (3/30) in Baiyun district and 9.7% (7/72) in Conghua district. Among the 10 positive samples, 9 were single infection (8 isolates, assemblage A; 1 isolate, assemblage F) and 1 sample was mixed infection with assemblages A and C. Based on tpi, gdh, and bg genes, all sequences of assemblage A showed complete homology with AI except for 1 isolate (CHC83). These findings not only confirmed the occurrence of G. duodenalis in stray cats, but also showed that zoonotic assemblage A was found for the first time in stray cats living in urban and suburban environments in China.

In the present circumstance of exploring measures for sustainable development, finding and using planning elements of historical city is getting important as a urban planning tool. Thus this study aims to examine the characters of Korean traditional urban form through three periods, Josun, modern and contemporary eras. Three urban centers representing different characteristics were selected; historical center based on 14th century's traditional planning, modern period urban center, which is related with development of railway, and contemporary urban center of late 20th century. Analyse of urban tissue, composed with form and scale of street network, blocks and plots, shows that each urban center of Seoul has certain common attributes in terms of morphology in spite of the difference of formation and development period. However this historical urban forms are rarely applicated in the current urban planning, such as new-town planning or district unit plan. This shows the necessity of modification of urban regulation for preserving the identity of our city and pursuing sustainable development.

Objective of Urban regeneration is a recovery of urban utilities through a physical, environmental, cultural, industrial and economic regeneration. The current paradigm of urban regeneration is not a simple redevelopment as physical redevelopment or improvement. This study is proposed that value system management applied the benefit management, value system, Quality Function deployment for a value conflict of urban regeneration. There is a reason to conflict value that value system is unstructured. Because this study is proposed to establish the process of value system, and applied this process to Se-woon 4th area urban regeneration project. This study is analyzed to divide value system of urban regeneration program into city level, district level, zone level in district. An analysis of value system obtained through '2020 urban master plan', 'the downtown recreate a comprehensive plan', 'Se-woon New town plan'. It is proposed that value system management method through Between values correlation analysis and the order of priority deduction. These are obtained to use Delphi technique and Analytic Hierarchy Process(AHP)

The purpose of this study is to evaluate the urban land used by the Urban Land Use Information System (ULIS) which can supply the micro-level land usc information for the understanding of micro-level urban spatial structure and district-level planning and managements(such as urban design, redevelopment planning and district-level transportation planning, etc.). The study evaluates the current situation of urban land use database and suggests the prototype of urban land use database using GIS. The planning and management of post-modern city which has characterized by diversity and the mixture of land use, need more detail and quantitative information about land use. Recent redevelopment and reconstruction of existing physical condition are increasing the density of activity. It raises urban problems such as the shortage of infrastructure and traffic congestion, etc. In this process we need to construct information system which monitors current land use situation.

This paper analysis spatial correlation applying commercial activating factor and categories clusters among have homogeneity in garosu street which are rising commercial issue in residential district. Based on this research we can draw several implications. Firstly, Garosu street are forming unique space around fassion feature like clothes and food and Beverage stores are supporting main functions. secondly, in terms of utilization of semi-public space in individual buildings, main Street are using display goods and put product.Also restaurants and cafes are using public space as terrace seats. These results mean principal road emphasizes displaying and passing but inner road emphasizes taking a break and staying. Third, repetitive action between high rising vacancy and new building cause negative effects city decline and lossing identity. So residents and merchants should cooperate and make communities for sustainable district.

The purpose of this research is to analyze of biotope structure focused on the evaluation for the species and biotope preservation in the case of Soosung District in Daegu metropolitan city. We analyzed the structure of urban biotope, and investigated the disposition of space and several characteristics through the material collection relating to the existing urban ecological material and the field investigation. The results of this study were as follows; 1) The result of biotope type classification was divided into 17 biotope type groups and 90 biotope types belonging to them. 2) The biotope type of mixed forest(QD) has the highest rate in occupation area, 1.764ha and the biotope type of cultivation areas by vinyle-hothouse(KC) has the lowest rate, 0.3ha. 3) In the result of the first evaluation for the species and biotope preservation, biotope types such as QB, QI, PA, PB, NB and NC etc. possess great value. Particulary, these biotope types come from forest areas and transition zone. They have not appeared in the inner of cities. 4) The biotope types such as CA, NA, NB, ND and PB are proved to possess high value in the result of rarity and riskiness evaluation. There appear EE, MA, NB, QC and QD in IV grade which is impossible to have them regenerative. They usually have appeared in forest areas. 5) There emerge 3a biotope type that has the highest value in the result of the second evaluation such as CC, EE, KF, LD, MB, NC, PB, QB and QI etc. Most of them were presented into the large area of site size and were distributed in the forest areas intensively. So, it is certain that the space for the species and biotope preservation connected with residential district is scarce. 6) The detailed biotope plan must be made out specially continuously. It is about biotope spaces that are especially important for the species and biotope preservation from the result of this research. Also, the study on the detailed index settlement of the urban landscape plan based on the biotope map must be continued.

Nihombashi district, which is located in a heart of Tokyo Metropolitan area, has been flourished as a Japanese economic and cultural center since Tokyo was developed as a capital. Nihombashi district has still remained the Edo idea of stylishness since the government of Edo was established in 1603. During Edo period, population of Edo (former name of Tokyo) reached one million. Edo became one of big city around the world. Nihombashi district has been transformed as economical, financial and cultural center, along with modern transformation of Tokyo. During high economic growth (1955-1975), Nihombashi Bridge and River, which used to a symbol of Tokyo, have been covered with elevated highways. The river was polluted whereas the river does not have any relationship with people's daily activities. Since Japan has focused on environment concern in 80's, people and companies in Nihombashi district and Nihombashi River also requested to restore Nihombashi district and Nihombashi River. There are a lot of projects going on related to regenerate the river and the community, such as to remove highways covered with the river, restore river environment and run water navigation. This article mentioned to introduce the project of Nihombashi River and Nihombashi district that regenerate the community to capitalize history and geographic characteristics in Nihombashi district, to run water navigation through the river, and to review outcomes through various projects.
